[0018] [Figure 1]Design of the rAAV vector, CBA-mβgal-WPRE. Figure 1A shows a schematic diagram of the rAAV vector, CBA-mβgal-WPRE. Two inverted terminal repeats (ITRs) derived from AAV2 flank the vector at each end. The CBA promoter consists of a chimeric chicken beta-actin / rabbit beta-globin intron (CBA) followed by a cytomegalovirus immediate-early enhancer (CMV) fused to the chicken beta-actin promoter, mouse lysosomal acid beta-galactosidase cDNA (mβgal), a woodchuck hepatitis virus posttranscriptional regulatory element (WPRE), and two tandem poly(A) signals derived from bovine growth hormone (BGH) and SV40. This vector was then packaged into an AAVrh8 capsid. Figure 1B shows a recombinant AAV (rAAV) vector containing a transgene encoding hGLB1 under the control of the CBA promoter. [Figure 2] Figure 2 shows that intracranial injection of AAVrh8-mβgal into βgal- / - mice results in dose-dependent enzyme distribution. βgal expression in the brains of representative AAVrh8-injected animals and age-matched controls was analyzed by histochemical staining of 20 μm coronal brain sections with X-gal and counterstaining with Nuclear Fast Red at 2 weeks (4 × 10 vg) or 3 months (2.6 × 10 vg and 2.6 × 10 vg) after injection. Figures 2A-2B show 4 × 10 vg; Figures 2E-2F show 2.6 × 10 vg; Figures 2I-2J show 2.6 × 10 vg; Figures 2C-2D show naive βgal- / - mice; and Figures 2G-2H show naive βgal+ / - mice. Images represent N≥3 mice per group. [Figure 3]Figure 3 shows that βgal- / - mice intracranially injected with AAV retain significant motor function on the rotarod. Animals were assessed for motor function in an accelerating rotarod test (4-40 rpm over 5 min). The best score from three trials was recorded. Using a nonparametric, unpaired Student's t-test and Walsh correction, βgal- / - animals treated with a total dose of AAVrh8 vector (Figure 3A) 4 x 1010 vg; (Figure 3B) 2.6 x 1010 vg; and (Figure 3C) 2.6 x 109 retained significantly better motor function than naive βgal- / - controls at 6 months post-injection (P = 0.006, 0.0009, and 0.005, respectively). N = 3-15 animals per group at each time point, and N = 6-10 animals per group at 6 months post-treatment. [Figure 4] Figure 1 shows that βgal- / - mice intracranially injected with AAV achieve a significant lifespan extension. Kaplan-Meier survival curves for βgal- / - mice treated with intracranial AAVrh8. Using the log-rank (Mantel-Cox) test, mice treated with AAVrh8 vector at total doses of 4x1010vg, 2.6x1010vg, and 2.6x109vg all showed a significant (p=0.0004, p=0.002, p<0.0001, respectively) extension in lifespan compared to naive βgal- / - controls. Median survival was increased from naive βgal controls (245.5 days, N=13) to the 4x1010vg cohort (293.5 days, N=12), 2.6x1010vg cohort (349.0 days, N=13), and 2.6x109vg cohort (389.0 days, N=13). [Figure 5]Figure 5A shows that intracranial injection of AAV in βgal- / - mice results in abnormal filipin staining within the region of highest enzyme expression. Figure 5A shows a coronal section of the mouse brain stained with Xgal for the presence of βgal enzyme and counterstained with Nuclear Fast Red 12 weeks after injection of a representative βgal- / - mouse (knockout + AAV) bilaterally injected into the thalamus with 1 μl of AAVrh8-CBA-mβgal-WPRE (total dose of 2.6 × 10 vg). Figure 5B shows an untreated βgal- / - mouse (untreated knockout). Boxes indicate the location of images depicted in Figures 5C-5F. Flipin staining in adjacent brain sections from a βgal- / - animal treated with 2.6 × 10 vg of AAVrh8-CBA-mβgal-WPRE is shown in Figures 5C and 5E. Figures 5D and 5F show untreated βgal mice (untreated knockout). Images of filipinas taken at 10x magnification. Images represent N≧3 mice per group. [Figure 6] These figures show that lysosomal accumulation persists in the spinal cord of long-lived βgal- / - mice intracranially injected with AAV. Spinal cord sections cut at 20 μm were stained with filipin for GM1 ganglioside accumulation. All long-lived animals showed some amount of intraspinal clearance, but also contained areas where clearance did not occur. Figures 6A and 6B show data 621 days after injection of 4×1010 vg. Figures 6C and 6D show data 547 days after injection of 2.6×1010 vg. Figures 6E and 6F show data 495 days after injection of 2.6×109 vg. Figures 6G and 6H show generalized accumulation approximately 250 days after injection in naive βgal- / - mice. Images represent N≧2 mice per group. [Figure 7]Figure 7 shows that intracranial injection of AAV in βgal- / - mice results in morphological changes at the injection site in the thalamus. Intracranially injected βgal- / - mice were analyzed by H&E staining of 20 μm coronal brain sections 2 weeks (4 × 10 vg) or 3 months (2.6 × 10 vg and 2.6 × 10 vg) after injection. Shape changes within the injected area of ​​the thalamus: thick arrows indicate cellular infiltration into blood vessels, and thin arrows indicate inflammation. The left panel is a 10x magnification, and the right panel is a 40x magnification (from the area above the left panel). Shape changes and neuronal loss appear to be attenuated even with the lowest injected dose. Figures 7A and 7B show the 4 × 10 vg injection after 2 weeks of treatment. Figures 7E and 7F show the 2.6 × 10 vg injection after 3 months of treatment. Figures 7I and 7J show injections of 2.6 x 109 vg 3 months after treatment. Figures 7G and 7H show untreated naive βgal+ / - at the age of treated animals. Figures 7C and 7D show untreated naive βgal- / - at the age of treated animals. Figure 7K shows a cerebrum injected with AAVrh8-mβgal. Red arrows indicate the injection site in βgal animals and the location of the photographs shown in this figure. Scale bar represents 100 um. Images represent N > 3 mice per group. [Figure 8]Figure 8 shows that intracranial injection of AAV in βgal- / - mice results in morphological changes at the injection site within the deep cerebellar nuclei. Intracranial-injected βgal- / - mice were analyzed by H&E staining of 20 μm coronal brain sections 2 weeks (4 × 10 vg) or 3 months (2.6 × 10 vg and 2.6 × 10 vg) after injection. Morphological changes were observed within the injected area of ​​the DCN. The thick arrow indicates cellular infiltration into blood vessels. Arrows point to infiltration suspected to be phagocytic neurons. The left panel is a 10x magnification, and the right panel is a 40x magnification photograph (from the area depicted on the left panel). Shape changes and neuronal loss appear to be attenuated even with the lowest injected dose. Figures 8A and 8B show 4 × 10 vg injections 2 weeks after treatment. Figures 8E and 8F show injections of 2.6 x 10 vg 3 months after treatment. Figures 8I and 8J show injections of 2.6 x 10 vg 3 months after treatment. Figures 8G and 8H show untreated naive βgal+ / - mice at the age of treated animals. Figures 8C and 8D show injections into naive βgal- / - mice at the age of treated animals. Figure 8K shows a DCN injected with AAVrh8-mβgal. Arrows indicate the injection site in βgal animals and the location of the photographs shown in this figure. Scale bar represents 100 um. Images represent N > 3 mice per group. [Figure 9]Figure 9 shows that intracranial injection of AAV in βgal+ / − and βgal− / − mice results in abnormal filipin staining within the region of maximal expression of the enzyme. Sagittal sections of mouse brains stained with Xgal for the presence of βgal enzyme and counterstained with Nuclear Fast Red 10 weeks after injection of representative (Figure 9A) βgal+ / − mice (chimera + AAV) and (Figure 9B) βgal− / − mice (knockout + AAV), and (Figure 9C) untreated βgal− / − mice (untreated knockout), were injected with 1 μl of AAVrh8-CBA-mβgal-WPRE bilaterally into the thalamus at 1.7 × 1012 vg / μl, 2 μl into the ventricles, and 0.3 μl into the deep cerebellar nuclei. Boxes indicate the locations of images depicted in Figures 9D-9I. Filipin staining was positive within the region of maximal enzyme expression in both chimera and AAV-injected animals (Figures 9D, 9G, and 9J; βgal+ / −) and βgal− / − knockout and AAV-injected animals (Figures 9E, 9H, and 9K). Figures 9F, 9I, and 9L show that filipin content was unchanged in untreated βgal− / − mice (untreated knockout). Filipin staining on brain sections taken at 10x magnification. Images represent N≥3 mice per group. [Figure 10]These figures show that changes in vector design result in the presence of β-gal protein and / or reduced β-gal enzyme activity in β-gal mice. Figure 10A shows β-gal enzyme activity within the injected structures of 2 mm × 2 mm biopsy punches. Approximately 6 weeks after injection, 1 μl of AAVrh8 vector (3.4 × 10 vg, or 2.0 × 10 vg total dose for high-dose CB6 alone) or mock-treated PBS was injected bilaterally into the thalamus, as determined by 4-MU assay. Enzyme activity was normalized to protein concentration by Bradford reagent and is reported as nanomoles per hour per mg of protein. Error bars represent mean + SD, N = 3 per group. * indicates significant differences between β-gal + / - AAV (chimera + vector name) and untreated β-gal + / - (untreated chimera), or as indicated by a connecting line. P values ​​calculated using an unpaired multiple t-test (Holm-Sydac), where *=p<0.05, **=p<0.01, and ***=p<0.001. Figure 10B shows the presence of endogenous β-gal protein, as determined by Western blot, which appears at 67 kd, while expression of the transgene from the AAV vector appears as a higher-mass band. The loading control is actin, which appears at 42 kd. Western blots shown represent N=3 per run.

Number of vector genomes per diploid genome within the injected structure of a 2 mm x 2 mm biopsy punch when 1 μl of AAVrh8 vector (3.4 x 109 vg or 2.0 x 1010 vg total dose in high-dose CBA alone) was injected bilaterally into the thalamus of βgal+ / − mice (chimera + vector name), as determined by qPCR for SV40 polyA on the transgene. Samples were taken 6 weeks after injection. Error bars represent mean + SD, N = 3 per group. * indicates significant differences using an unpaired multiple t-test (Holm-Sydac), indicated by a connecting line, where * = p < 0.05, ** = p < 0.01, and *** = p < 0.001.

Figures 12B, 12E, 12H, 12K, 12N, and 12Q show filipin staining in parallel sections of the same animals in Figures 12A, 12D, 12G, 12J, 12M, and 12P.

Boxes represent the approximate locations of filipin and ToPro3 staining on brain sections taken at 20x magnification. Scale bar = 250 μm. Images represent N > 2 mice per group. [Figure 13]Figure 1 shows that clustering heat maps and Venn diagrams for all differentially expressed genes in βgal+ / − mice confirm transgene expression-dependent variation. Clustering heat maps and Venn diagrams for all differentially expressed genes were generated using data from 2mm x 2mm biopsy punches from the thalamus of βgal+ / − mice (chimera + vector name) injected with 1 μl of AAVrh8 vector (total dose of 3.4 x 109 vg) or mock-treated with PBS approximately 6 weeks after injection. Microarray results were determined using Affymetrix Mouse Gene 2.0 ST, N = 3 per group, P < 0.05, > 1.8-fold change.

[0023] Figure 1 shows that therapeutic treatment with AAVrh8 in the CNS of βgal- / - mice results in normalization of GM1 content when treated with a high dose of a low-expressing promoter. GM1 content was quantified by LC-MS / MS in the cerebrum, cerebellum + brainstem, or spinal cord of βgal- / -, untreated (untreated knockout), or untreated βgal+ / + (untreated wild-type) mice 6 weeks after injection of 1 μl of AAVrh8 vector (3.4 × 109 vg, or a total dose of 2.0 × 1010 vg for the high-dose CBA group only) into the thalamus bilaterally and 0.3 μl into the DCN. GM1 content is expressed as ng of GM1 per μg of protein. Values ​​represent mean + SD, N≧3 per group, * indicates significant difference of knockout+AAVrh8 versus knockout+PBS using a multiple t-test (Holm-Sydac) or significant difference indicated by a connecting line, where *=p<0.05, **=p<0.01, and ***=p<0.001. [Figure 19] FIG. 1 depicts the structure of the AAVrh8 vector. [Figure 20]FIG. 1 shows a vector map for 2140.8 pAAV-cb-mβgal. [Figure 21] FIG. 1 shows the structure of a monocistronic AAV vector encoding the HexA alpha and beta subunits. [Figure 22] Neuropathology in the monkey thalamus. Figure 22A shows mononuclear cell infiltration around blood vessels (arrows) and areas of necrosis (*) within the white matter. Figure 22B shows a cross section stained with Luxol Fast Blue, where the arrow highlights one large area of ​​necrosis, vascular proliferation, and white matter loss (note the pale color compared to the adjacent dark blue). Figure 22C shows a necrotic area (arrow) within the thalamus with vacuolization. Figure 22D shows an example of cellular infiltration into blood vessels within the thalamus (40x magnification). Similar neuropathology was also seen with the lowest dose (1 / 30) (Figure 22E). Figure 22F shows a normal thalamus in a PBS-injected animal (1x dose: Figures 22A-22D; 1 / 30 dose: Figure 22E; PBS injection: Figure 22F). [Figure 23] Figure 1 shows hexosaminidase activity in the CNS. Hex activity was measured in the thalamus and thoracic spinal cord of NHPs injected with different doses of a 1:1 formulation of AAVrh8 vectors encoding cynomolgus monkey Hex-alpha and cynomolgus monkey Hex-beta. Two artificial substrates, MUG and MUGS, were used in the biochemical assay. The first substrate is cleaved by all Hex isozymes (HexA, HexB, and HexS), whereas the latter is cleaved only by HexA and HexS isozymes. [Figure 24] (Figure 1) Pre-necropsy brain MRI revealing edema within the thalamus. Pre-necropsy thalamic edema (arrow) in an NHP injected with a 1 / 30th dose of a formulation of AAVrh8 vector encoding cynomolgus Hex-alpha and cynomolgus Hex-beta. No changes were observed in NHP injected with an empty transgene AAVrh8 vector. [Figure 25]Figure 25 shows protein expression in monkey thalamus. Hex-β staining (green) is shown proximal (FIG. 25A) and distal (FIG. 25B) to the injection site in the thalamus of a 1× dose animal. Hex-α staining (green) is shown proximal (FIG. 25C) and distal (FIG. 25D) to the injection site in the thalamus of a 1 / 30 dose animal. H&E staining is shown proximal (FIG. 25E) and distal (FIG. 25F) to the injection site in the thalamus of a 1 / 30 dose animal shown in FIGS. 25C-25D. Figure 25G shows an enlarged view of the boxed area in Figure 25E. Arrows indicate eosinophilic material within neurons. [Figure 26] Figure 26 presents a panel of new AAV vectors with a gradient of predicted HexA expression levels. Figure 26A shows the systematic removal of expression elements from the latest version (top) to its most basic form (bottom vector), which consists of ITR-flanked cDNA with a polyadenylation signal and no classical promoter elements, while Figure 26B shows ITR expression-based vectors that progressively incorporate more elements known to increase ITR-driven gene expression. Abbreviations: CMV Enh: cytomegalovirus immediate-early enhancer; CB: chicken beta-actin promoter; HexA / B: for each vector design, a pair of vectors carrying cynomolgus monkey HexA cDNA and cynomolgus monkey HexB cDNA is generated; pA: polyadenylation signal; ITR: AAV2 inverted terminal repeat; P1: promoter 1, which is thought to increase ITR-mediated gene expression approximately 10-fold; P2: promoter that is thought to increase ITR-mediated gene expression approximately 50-fold.

[Figure 29]Figure 29 shows the gradient of hexosaminidase activity in transiently transfected 293T cells. Hexosaminidase activity was measured in cell lysates 72 hours after transfection using artificial substrates, 4MUG (Figure 29A) and 4MUGS (Figure 29B), which are cleaved by all beta-hexosaminidase isoforms (HexA, HexB, and HexS) or only the alpha-subunit-containing isoforms (HexA, HexS), respectively. [Figure 30] Figure 1 shows the change in body weight over the one-month study period. Error bars represent 1 standard deviation. [Figure 31] Figure 31 shows that mouse brains expressing the highest levels of cynomolgus monkey Hex protein contain eosinophilic neurons. H&E staining indicates the presence of neurons containing eosinophil granules in the hippocampus and thalamus, which correlates with the expression level of cynomolgus monkey Hex (40x magnification).

[Figure 32] Figure 32 shows that expression of cynomolgus monkey Hexα in the brains of athymic nude mice varies among AAV vectors. Hexα staining (green) in the thalamus and hippocampus of mice from Group 1 (Figures 32A, 32K), Group 2 (Figures 32B, 32L), Group 3 (Figures 32C, 32M), Group 4 (Figures 32D, 32N), Group 5 (Figures 32E, 32O), Group 6 (Figures 32F, 32P), Group 7 (Figures 32G, 32Q), Group 8 (Figures 32H, 32R), Group 9 (Figures 32I, 32S), and Group 10 (Figures 32J, 32T) is shown; nuclei are counterstained with DAPI (blue). Arrows indicate enzyme-positive cells. [Figure 33]Figure 33A-33K shows that reduced expression of cynomolgus monkey Hex protein results in reduced microglial activation. Iba-1 staining indicates reduced inflammation in the hippocampus and thalamus in groups with reduced expression of cynomolgus monkey Hex protein (20x magnification).

[Figure 35] FIG. 1 shows new AAV vectors selected for further testing in non-human primates. [Figure 36] Figure 1 shows relative total Hex activity in athymic nude mice intracranially injected with AAV vectors encoding cynomolgus Hexα and cynomolgus Hexβ. Enzyme activity of HexB, HexA, and HexS in vitro (C1: olfactory bulb and first 3 mm coronal slice of cerebrum, C2: subsequent 2 mm coronal slice of cerebrum, C3: subsequent 3 mm coronal slice of cerebrum containing injection site, C4: subsequent 2 mm coronal slice of cerebrum, CRBL: cerebellum, BS: brainstem, SC: spinal cord) measured with MUG substrate and normalized to naive mice. [Figure 37]Figure 1 shows relative HexA and HexS activity in athymic nude mice intracranially injected with AAV vectors encoding cynomolgus Hexα and cynomolgus Hexβ. HexA and HexS enzyme activity in vitro (C1: olfactory bulb and first 3 mm coronal slice of cerebrum, C2: subsequent 2 mm coronal slice of cerebrum, C3: subsequent 3 mm coronal slice of cerebrum containing injection site, C4: subsequent 2 mm coronal slice of cerebrum, CRBL: cerebellum, BS: brainstem, SC: spinal cord) measured with MUGS substrate and normalized to naive mice. [Figure 38] Figure 38 shows MRI analysis of targeting and distribution after intraparenchymal injection. Figure 38A shows pre- and post-operative intracerebral MRI using different sequences. The AAVrh8 vector formulation contains 2 mM gadolinium to analyze the distribution of the injected solution using T1-weighted MRI; the gadolinium distribution volume (Gd-enhanced volume) in this animal was 1.67 mL. Figure 38B shows the distribution volume (Vd) and mean + SD for each NHP; the total injected volume (Vi) within the thalamus was 0.3 mL. [Figure 39] 1 shows brain MRI of NHPs injected with AAVrh8 over the course of the 90-day experiment. Arrows indicate areas of hyperintense signal within the thalamus in three NHPs. [Figure 40] Figure 40 shows intracerebral MRI hyperintensities detectable in the thalamus of some AAVrh8-injected NHPs 90 days after injection. One NHP in cohort 1 (Figure 40A) showed a large hyperintensity in the left thalamus at the 90-day imaging timepoint, which was undetectable at earlier imaging timepoints. Figure 40B shows an NHP in cohort 2 in which bilateral hyperintense signals were detected beginning at day 30 and remained unchanged through day 90. In Figure 40C, an NHP in cohort 3 showed a hyperintense signal in the left thalamus from days 30 to 90. [Figure 41]Biopsy sampling of coronal brain sections. Higher than normal hexosaminidase was measured in the right (R) or left (L) thalamus in dorsal (D) and ventral (V) samples. [Figure 42] FIG. 1 shows neuropathological findings in the brains of Cohort 1 NHPs, including intraneuronal accumulation of eosinophil granules, neurodegeneration, and neuronal erosion. [Figure 43] Figure 43 shows severe focal spongiosis with perivascular cellular infiltration in the left thalamus of one monkey injected with AAVrh8 within cohort 1. Figure 43A was taken at 4x magnification; Figure 43B was taken at 10x magnification. [Figure 44] Figure 44 shows observations of neuropathology in monkeys from Cohort 3. Neurodegeneration was rare in these monkeys (Figure 44A), although monkey 295709 showed evidence of perivascular lattice cells, likely related to the injection route (Figure 44B). [Figure 45] FIG. 1 shows the assessment of intraneuronal accumulation of eosinophilic material in the right and left thalamus of monkeys in cohorts 1 and 3. [Figure 46] FIG. 1 shows the assessment of neurodegeneration and necrosis in the right and left thalamus of monkeys in cohorts 1 and 3. [Figure 47] FIG. 1 shows the inflammation ratings in the right and left thalamus of monkeys in cohorts 1 and 3. [Figure 48]Figure 1 shows that intracranial injection of AAVrh8-cmHex vector results in increased Hex expression and reduced GM2 ganglioside content in the brains of Sandhoff mice. Six- to eight-week-old Sandhoff mice received intracranial injections of PBS (n=1; purple bar; n=1), AAVrh8-CBA-cmHex-W (green bar (A), n=3, 4.68 × 10 vg), AAVrh8-CBA-cmHex (orange bar (B), n=3, 4.68 × 10 vg), or AAVrh8-CB-I-cmHex (blue bar (C), 4.68 × 10 vg; C (5x dose): 2.34 × 10 vg; n=4) vectors. Brains were harvested 4 weeks after injection and sectioned into 2-3 mm coronal blocks as shown in the schematic above; vertical arrows indicate the injection sites. In Figures 48A-48C, total Hex enzyme activity (HexA, HexB, and HexS) was measured using an artificial substrate, MUG, and expressed as fold increase relative to wild-type levels (WT, black bars, n=1). An asterisk (*) represents an animal with no detectable Hex activity. Figures 48D and 48F are bar graphs of the qualitative LC-MS / MS used to measure GM2 ganglioside content. [Figure 49-1] 49A and 49B show structural renderings for the promoters described by the present disclosure. Figure 49A shows a structural rendering for the CB promoter, represented by SEQ ID NO:1. [Figure 49-2] Figure 49A shows a structural rendering of the promoters described by the present disclosure. Figure 49B shows a structural rendering of the CB(6)-I promoter, represented by SEQ ID NO:4. [Figure 49-3] Figure 49C shows a structural rendering for the promoters described by the present disclosure. Figure 49C shows a structural rendering for the P2-I promoter, represented by SEQ ID NO:5. [Figure 50] FIG. 1 shows a schematic representation of the dual promoter AAV9-Syn1-GFP-2×miRSO D1 / GFAP-2×miRSOD1-mCherry vector. [Figure 51]Figure 1 shows the transduction profile for the dual promoter AAV9-Syn1-GFP-2xmiRSOD1 / GFAP-2xmiRSOD1-mCherry after intrastriatal injection in adult SOD1G93A mice. The AAV9 vector contained GFP driven by the intraneuronal synapsin 1 promoter and mCherry driven by the astrocytic GFAP promoter. The shapes of GFP (green)- and mCherry (red)-expressing cells correspond to those of neurons and astrocytes, respectively. [Figure 52] This figure shows that human SOD1 mRNA levels are reduced in adult SOD1G93A mice after injection of the dual-promoter AAV9-Syn1-GFP-2×miRSO D1 / GFAP-2×miRSOD1-mCherry vector. The artificial microRNA (miR) targets human SOD1. After intravenous injection of 1×10 12 total vector genomes, a maximum 25% reduction in human SOD1 mRNA expression in the spinal cord was observed. After direct intrastriatal injection of 8×10 9 total vector genomes, a maximum 55% reduction in human SOD1 mRNA expression in the striatum was observed. [Figure 53]

[0049] Figure 53 shows that intracranial treatment with AAVrh8-mHEXA / B extends the lifespan of Sandhoff disease (SD) mice, resulting in the preservation of motor function. SD mice treated with 4.68 x 10 vg of AAVrh8-mHexA / B vector formulations via TH / ICV or TH / DCN delivery were assessed for performance in the (Figure 53A) reversal screen test, (Figure 53B) rotarod test, and (Figure 53C) wire hang test at 60, 120, and 180 days of age. Figure 53D shows Kaplan-Meier survival plots for SD mice treated intracranially with 4.68 x 10 vg of AAVrh8-mHexA / B, demonstrating that intracranial treatment in combination with bilateral intrathalamic (TH) injections, bilateral deep cerebellar nuclei (DCN) injections, or a single intracerebroventricular (ICV) injection results in comparable survival outcomes. [Figure 54]Figure 54A shows that intracranial AAVrh8-mHexA / B treatment in SD mice results in a dose-dependent extension of lifespan and improves motor function. Figure 54A shows Kaplan-Meier survival plots for a dose-escalation experiment of AAVrh8-mHexA / B injected intracranially via TH / ICV into 1-month-old SD mice. SD mice intracranially treated with 4.68 x 10 vg and 1.17 x 10 vg AAVrh8-mHexA / B vector formulations via TH / ICV delivery were assessed for performance in the (Figure 54B) reversal screen test, (Figure 54C) rotarod test, and (Figure 54D) wire-hanging test at 60, 120, and 180 days of age. [Figure 55] Figure 55: Intracranial delivery of AAVrh8-mHexA / B has minimal effect on motor performance in normal mice. The performance of heterozygous (HexB+ / −, HZ) mice treated with intracranial injection of 4.68×109 vg of AAVrh8-mHexA / B via TH / ICV or TH / DCN delivery was assessed at 60, 120, and 180 days of age in (Figure 55A) the reversal screen test, (Figure 55B) the rotarod test, and (Figure 55C) the wire-hanging test. [Figure 56] Figure 56 shows that intracranial delivery of AAVrh8-mHexA / B treatment reduces GM2 ganglioside accumulation and results in widespread hexosaminidase expression in the central nervous system of SD mice. SD mice were treated with 1.17 x 10 vg of AAVrh8-mHexA / B via TH / ICV injection, and neurochemistry was assessed at the same age as the humane endpoint for untreated SD mice. Using two artificial substrates: MUG (cleaved by HexA, HexB, and HexS isozymes) and MUGS substrate (cleaved by HexA and HexB isozymes), the cerebrum, cerebellum, and spinal cord were analyzed for (Figure 56A) GM2 ganglioside content and (Figure 56B) hexosaminidase activity. [Figure 57]Figures 57A and 57B show survival and biodistribution of AAV in SD cats after TH and ICV injections. Figure 57A shows that survival of untreated SD cats was 4.4±0.6 months. Figure 57B shows that the onset of clinical disease was delayed and clinical signs were alleviated in SD cats after AAV treatment. Figure 57C shows a crude image of the brain (left) indicating the location of the section. Figure 57C shows a coronal section of the right hemisphere of the brain and spinal cord in situ illustrating the location of the analysis. Figure 57D shows naphthol staining for histochemistry showing the distribution of Hex in normal cats, SD cats, and a representative SD cat treated with AAV. Figure 57E shows HexA enzyme activity in the brain and spinal cord of an SD cat. [Figure 58] Figure 58 shows biomarkers for the therapeutic efficacy of AAV-mediated gene therapy. Figure 58A shows 7T MRI of an SD cat brain, demonstrating increased gray and white matter intensity due to increased demyelination in the white matter and increased GM2 accumulation in the gray matter. Following TH / ICV delivery with AAV gene therapy, complete normalization of gray and white matter intensity is observed. Mild cortical atrophy is evident as the injection site in the thalamus is hyperintense. Figure 58B shows MR spectroscopy of an untreated SD cat, demonstrating increased N-acetylhexosamine, a toxic metabolite previously reported in SD patients. Following TH / ICV delivery with AAV gene therapy, this is completely normalized. Figure 58C shows an MR spectrum for a representative SD cat. Figure 58D shows HexA activity in cerebrospinal fluid (CSF) in an SD+AAV TH / ICV SD cat. Figures 58E and 58F show lactate dehydrogenase (Figure 58E) and aspartate aminotransferase (Figure 58F) levels in the CSF of normal (open circles), SD (filled circles), and SD+AAV TH / ICV cats (shaded circles). Figures 58G and 58H show serum antibody titers in SD+AAV TH / ICV cats 11-907 (Figure 58G) and 7-760 (Figure 58H). [Figure 59]Figure 59 shows the clinical therapeutic effect and biodistribution in SD+ intracisternal (CM) AAV cats. Figure 59A is a Kaplan-Meier curve showing a survival of 4.4 ± 0.6 months in untreated SD cats. SD cats treated with intracisternal AAV extended survival to 9.9 ± 0.5 months. Figure 59B is a clinical assessment score showing a rapid decline in untreated SD cats. In SD+AAV cats, decline was attenuated, with a prolonged plateau phenotype. Cats were euthanized due to visual and hearing loss as well as musculoskeletal abnormalities before loss of ambulation. The clinical assessment score was based on the following clinical signs: mild tremor, pronounced tremor, hindlimb weakness, drowsy gait, ataxia, accidental falls, limited ambulation, front leg spasms, hind leg spasms, and inability to walk. Normal score was 10, with 1 point subtracted for each symptom. Figure 59C shows a cat brain (left), with lines indicating the location of the brain cross-section, and the right hemisphere with the brain and spinal cord en bloc illustrating the location for biodistribution analysis. Figure 59D shows HexA activity in the brain and spinal cord of a SD+AAV long-term cat (MUGS). The thick line at 1 indicates normal levels. Figures 59E and 59F show HexA expression in various brain regions as measured by qPCR. [Figure 60] Figure 1 shows accumulation clearance in SD+AAV cisterna magna (CM) cats. Representative periodic acid-Schiff (PAS) staining for a normal cat (left), an SD cat (middle), and a cat chronically treated with SD+AAV CM. Normal cats exhibited darker PAS staining in the white matter of the cerebrum and cerebellum than in the gray matter, and the reverse was true for the spinal cord. SD cats exhibited darker PAS staining in the gray matter than in the white matter, with areas of loss of staining within the white matter (particularly evident in the spinal cord). SD+AAV cats treated by injection via the cisterna magna showed increased accumulation and demyelination in the cerebral cortex, with normalization in the cerebellum, brainstem, and spinal cord. [Figure 61]Figure 1 shows normalization of histopathology after AAV gene therapy. SD cats exhibit degenerated neurons in the microgyrus, DCN, and brainstem. Sixteen weeks after AAV gene therapy, SD cats showed normalized morphology in all of these regions, and in long-term AAV-treated animals, morphology was preserved, with the exception of Purkinje cell degeneration. Interestingly, within the dentate nucleus, a subset of neurons was found to contain grape-shaped eosinophilic inclusions (inset; scale bar: 5 μm). Scale bar: 10 μm. [Figure 62] Figure 62A shows biomarkers of disease progression and improvement in SD+AAV CM cats. Figure 62A is a 7T MRI of an SD cat showing cerebral cortical atrophy and hyperintense white and hypointense gray matter, consistent with white matter demyelination and lipid accumulation within the gray matter, compared to a normal cat. Intensity changes persisted in SD+AAV CM cats, but cortical atrophy improved. MR spectroscopy of the thalamus of an SD cat shows an increase in N-acetylhexosamine after 16 weeks of treatment, which is corrected by CM delivery of AAV. In one CM cat at the humane endpoint, NA Hex levels were further elevated. Figure 62B shows that myo-inositol (INS), a marker for gliosis, and glycerophosphocholine + phosphocholine (GPC + PCh), a marker for demyelination, also increased in SD+AAV CM cats. Figure 62C shows a representative MR spectrum. Figure 62D shows HexA in CSF in SD+AAV CM cats over time. Normal levels are indicated by dashed lines. Figures 62E-62H show aspartate aminotransferase (AST) activity, a marker of cytotoxicity, in CSF in normal cats (open circles), SD cats (filled circles), and SD+AAV CM cats (lightly filled circles). [Figure 63]Figure 63 shows that intracranial injection of the AAVrh8-CB-CI-mHexA / B vector reduces GM2 ganglioside accumulation in the CNS while increasing hexosaminidase activity, thereby improving survival in SD mice. SD mice received intracranial injections of the AAVrh8-CH-CI-mHexA / B vector at a total dose of 4.68 x 10 vg or 2.34 x 10 vg, or the original vector (4.68 x 10 vg), or PBS. Figure 63A shows the GM2 ganglioside content measured by LC-MS / MS 8 weeks after CNS injection. Figure 63B shows the hexosaminidase activity in the cerebrum measured using the MUG substrate 8 weeks after injection. The dashed line indicates the average activity of untreated wild-type animals. Results are shown as mean ± SD by Tukey's multiple comparison test; *(P≦0.05), **(P≦0.01), ***(P≦0.0001); n=4 for PBS, n=4 for original CBA-mHexA / B, n=6 for 2.34×1010 vg CB-CI-mHexA / B and 4.68×109 vg CB-CI-mHexA / B; nd (not detected). Figure 63C shows the survival and symptoms of SD mice (n=8) injected with 2.34×1010 vg AAVrh8-CB-CI-mHexA / B (study endpoint: 5 months). The median survival of untreated Sandhoff disease mice was 125.5 days (n=6). [Figure 64] Figure 64 shows that increasing the dose of AAVrh8-CB-CI-mHexA / B vector delivered to the CSF further reduces GM2 ganglioside accumulation in the spinal cord and cerebellum. SD mice were injected with 1.17×10 vg of AAVrh8-CB-CI-mHexA / B at increasing CSF doses (1.17×10 vg, 2.34×10 vg, 5.85×10 vg, and 5.5×10 vg) into the thalamus. Four weeks after injection, GM2 ganglioside content was measured in the spinal cord (Figure 64A) and cerebellum (Figure 64B) by LC-MS / MS. Results are shown as mean ± SD with Dunnett's multiple comparison test; *(P≦0.05), **(P≦0.01), ***(P≦0.0001), n=3.

(2) interfere with the promoter region's ability to direct transcription of the coding sequence; ) without interfering with the ability of the corresponding RNA transcript to be translated into protein. Thus, the resulting transcript is said to be operably linked to the desired target gene. The promoter region directs this DNA so that it can be translated into a protein or polypeptide. A promoter region is operably associated with a nucleic acid sequence if it is capable of effecting transcription of the sequence. Similarly, two or more coding regions may be linked together in a common promoter. These transcripts from the target gene are translated in frame into two or more transcripts. An operably linked protein is one that is operably linked when it is linked in a manner that results in expression of the protein. In some embodiments, the operably linked coding sequences encode a fusion protein.

Although activity was slightly reduced, the enzyme still spread throughout the structure. The low dose was 2.6 x 10 9 vg is widespread in both the cerebrum and cerebellum. The results showed that the α-glucan-containing α-glucan derivatives of α-glucan (Fig. 2I and 2J, respectively) reduced the risk of α-glucan-containing α-glucan (Fig. 2I and 2J, respectively).

[0159] AAV-treated animals retain motor function in a dose-dependent manner The motor function of AAVrh8-treated mice was assessed over time using the rotarod test. The results were evaluated using the AAVrh8-treated βgal - / - All cohorts were included in the 6 months of treatment. At the month later time point, untreated βgal - / - The results were significantly better than those of the control group (high use Quantity: 4×10 10 vg;p=0.006, medium dose: 2.6×10 10 vg;p=0.00 09, and low dose: 2.6 × 10 9 vg; p=0.005). Six months after treatment , N = 6-10 animals per group.

[0160] [Example 3] AAV treatment extends lifespan AAVrh8-treated βgal - / - Mice lifespan is significantly longer than that of naive βgal - / - Control and comparison The time to maturation was significantly prolonged (Fig. 4). - / - The median survival for controls was , 245.5 days (N=18), 4×10 10 For the vg cohort, 293. 5 days (N=12, p=0.0004), and 2.6 × 10 10 About the vg cohort was 349 days (N=13, p=0.002), and 2.6 × 10 9 Regarding the vg cohort For the control group, the mean mean was 389 days (N=12, p<0.0001).

[0161] GM1 ganglioside accumulation at the injection site and spinal cord of long-lived AAV-treated animals persist Lysosomal storage by filipin staining in the CNS of animals 3 months after injection Histological analysis of the amount of erythrocytes revealed no significant difference in the presence of the enzyme compared with Xgal staining at the same time point. In response to this, we found almost complete correction in the cerebrum and cerebellum (Figure 2). In contrast, filipin-positive cells were found only at the injection site or along the injection route. (Figures 5C and 5E).

[0162] βgal injected with AAVrh8 - / - Presence of filipin-positive cells in the mouse thalamus The present study showed that the maximum intensity of Xg in the brain, which is also a semiquantitative indicator of high β-gal enzyme activity, was This is surprising, since this is also the brain region that exhibits the most histochemical staining (Figure 5A, boxed). In the spinal cord of long-lived AAV-treated mice (495-612 days), lysosomal The effect on accumulation was observed in areas with very few remaining filipin-positive cells, and in areas with no treatment. Place βgal - / - The range of areas where no obvious changes were observed compared to the control was variable. (Figures 6A, 6D, 6F, and 6B, 6C, 6E, respectively).

[0163] [Example 4] Neuropathology at the injection site After early loss or 3 months after injection, animals were analyzed by hematoxylin / eosin (H&E) These animals showed dose-related changes in shape at the injection site. Two weeks after injection, βgal - / - +AAV4×1 0 10 vg was associated with cell infiltration into blood vessels and the appearance of inflammation (Figures 7A and 7B, respectively, indicated by thick arrows). Massive changes in the thalamus, such as vascular cellular infiltration, and clear Large phagocytic lesions in the DCN with extensive neuronal phagocytosis (thick arrows in Figure 8A and Figure 8B, respectively). Three months after treatment, the changes in the amount of βgal - / - +AAV2×10 10 v g also showed thalamic changes accompanied by cellular infiltration of blood vessels and inflammation (Fig. 7 E, 7F, thick and thin arrows). However, a dose of 2 × 10 10 vg βgal - / - + AAV resulted in only low-grade cell infiltration into blood vessels in the DCN (Fig. 8E, Taiya (See the symbol). 3 months after injection, the lowest dose representative animal, 2 × 10 9 vg βga l - / - In +AAV, only very slight inflammation was observed in the thalamus (Fig. 7J, This effect was not seen in the DCN (Fig. 8I, 8J). - / - Control (Figures 7C, 7D, and Figures 8C, 8D), or untreated βgal + / - Control (Fig. 7G, 7H, and Fig. 8G, 8H), neither cellular infiltration into blood vessels nor inflammation was observed. .

[0164] High levels of βgal induce unexpected responses within injected brain structures The paradoxical presence of filipin-positive cells at the injection site (Figures 5C and 5E) was due to the βgal - / - This may be the result of an unexpected response to AAV gene transfer in mice. To understand the phenomenon, normal, non-diseased β-gal + / - Littermates were injected with the AAVrh8 vector was injected intracranially. - / - Similar to the results in mice (Figures 5C and 5E), AA Vrh8 injected βgal + / - βgal staining in mice (Fig. 9D, 9G, 9J). There were also numerous filipin-positive cells within the brain regions with the highest intensity (FIGS. 9A and 9B). These results suggest that the presence of filipin-positive cells in the targeted brain structures is a key factor in the pathogenesis of AAV disease. This indicates an unexpected adverse response to certain aspects of gene transfer.

[0165] [Example 5] Enzyme activity, protein levels, and filipin-detection response of AAVrh8 capsid Validation of the AAVrh8 vector series to assess its contribution to To investigate the nature of unexpected responses at the injection site, we used the AAVrh8 vector. A series of vectors were designed (Table 1). Further vectors designed are shown in Figure 19. This AAVrh8 series will be referred to as "CBA-WPRE" from this section onwards. The transgene was inserted into the vector AAVrh8-CBA-mβgal-WPRE. The essence of this vector is the sequential removal of elements that affect the expression level of In "CBA", the woodchuck hepatitis virus post-transcriptional regulatory element (WPRE) is removed. Vector 3, "CBA-EI-WPRE", contains exactly the same bone structure as Vector 1. βgal protein, but carrying the E269Q mutation within the putative active site This vector encodes the . This vector allows for the determination of whether the observed response is caused by enzymatic activity. This study was designed to assess whether the effects of the β-glucan on the oxidative stress response were caused by the production of a protein. Vector 4, "CB6," contained mβgal cDNA but not in other vectors. This vector did not carry the WPRE or chimeric intron present. "Low-dose CB6" (same dose as all other vectors), and "High-dose CB6" (2.0 × 10 10 Two doses of vector 5, an "empty transgene" or "T.Empty" contained all the components of Vector 1 but not the mβgal cDNA. Missing A.

[0166] The newly constructed AAVrh8 vector was injected into the cells at a high dose (2.0 × 10 10 vg total dose In contrast, 1 μl per site was also injected, except for the CB6 vector, which Normal βgal + / - injected into the thalamus of mice (3.4 × 10 9 vg total dose Controls were injected with phosphate buffered saline (PBS). βgal + / - mice, and naive βgal + / - The enzyme activity in the thalamus was Sex and protein production were measured 6 weeks after injection of 4-methylumbelliferyl (4-MU) ) as measured by biochemical assays and Western blot (Figure 10).

[0167] [Table 1]

[0168] The CBA-WPRE vector is a naive βgal + / - Enzyme activity in the thalamus of mice (Fig. 10A), the highest enzyme activity and corresponding protein increase (Fig. 10B, Lane 1). The CBA vector + / - 224 times the level of βga This resulted in β1 activity, which was not observed with the CBA-WPRE vector. gal activity (Fig. 10A, p=0.001), and the protein product This resulted in a correspondingly clear decrease (Fig. 10B, lane 2). In the thalamus of vector-injected mice, βgal activity was significantly higher than in naive control mice. βgal activity (Fig. 10A), but the protein was The protein was expressed at a level comparable to that in the thalamus (Fig. 10B, lane 1). Therefore, the E269Q mutation impairs the enzyme activity but not the protein expression level. injection of the CB6 vector (low dose CB6) at the same dose as other vectors. 6) is βgal + / - βgal activity was 54-fold higher than in the control group (Fig. 4A). Accordingly, this results in lower amounts of protein than with other vectors. (Fig. 10B, lane 4). Injection of this vector at a high dose (high dose CB6) is βgal + / - This resulted in 420-fold higher β-gal activity than the levels induced by This was significantly higher than the β-gal activity in the low-dose CB6 cohort (Figure 1). 10A, 10B, p=0.03). β-gal activity levels within the high-dose CB6 cohort were significantly higher than those in the C The β-gal activity levels were comparable to those measured within the BA-WPRE cohort, and the protein levels The results were comparable for both the bell and the bell (Figures 10A and 10B, lane 1 compared with lane 5). The thalamus of animals injected with empty transgene vector (T.Empty) or PBS was compared with that of naive mice. Buβgal + / - Changes in β-gal activity or protein levels compared to levels in The vector genome coding region in the AAV-injected thalamus showed no expression (Fig. 10A, 10B). The number of peaks was 3.4 × 10 except for the T.Empty cohort. 9 injected with a total dose of vg , were shown to be comparable within most cohorts (Figure 11). As expected, 2.0 × 1 0 10 The high-dose CB6 cohort injected with CB6 showed a significant increase in vector genome copy number. The results showed that the α-glucan was significantly increased (Figure 11).

[0169] Filipin detection response correlates with protein levels βgal injected with AAVrh8 + / - mice, and control βgal + / - Mouse Brains were analyzed for β-gal enzyme activity by X-gal staining (Figs. 12A, 12D, 12E). G, 12J, 12M, 12P, 12S), the presence or absence of filipin-positive cells in the thalamus The presence of α-glucan was analyzed (Figures 12B, 12E, 12H, 12K, 12N, 12Q, and 12T). The thalamic regions with the greatest intensity of βgal staining (Figures 11A, 11D) were also CBA-WP RE- and CBA-injected animals also contained filipin-positive cells, but the latter Within the cohort, CBA-EI-WPR were clearly underrepresented (Fig. 11B, 11E). The thalamus in the E cohort contained numerous filipin-positive cells but no active β-gal enzyme. Similar filipin staining was not observed in the T-Empty control cells (Fig. 11K and 11J, respectively). This was also evident in the thalamus of the low-dose CB6 cohort (Fig. 11K, 11Q). observed within the CBA-WPRE and CBA-EI-WPRE cohorts The filipin staining was also highly used. The pattern was also observed within the thalamus of the CB6 cohort, and was consistent with that observed within the CBA-WPRE cohort. This is a mix of patterns expected and those observed within the low-dose CB6 cohort. These results suggest that abnormal filipin accumulation occurred at the injection site (Fig. 11H). This indicates that the expression level of the protein is correlated with its activity, but not with its enzyme activity.

[0170] Transcriptome changes in the injected thalamus were consistent with abnormalities detected by filipin. correlates with a positive response Microarray analysis was performed in the thalamus to assess physiological changes induced by gene transfer. We further characterized the tissue response to CBA-mβgal-WPRE. cohort, low-dose CB6 cohort, T.Empty cohort, and PBS-injected cohort The transcriptome changes (fold changes > 100%) for all analyzed samples were The difference between the low-dose CB6 sample and the control sample (1.8-fold, p<0.05) is shown in the heat map (Fig. 13A). The T.Empty and PBS samples clustered together, and were distinct from the CBA-WPRE samples. The number of genes with a >2-fold change in expression level was duplicated in the CBA-WPRE samples. The number of genes was significantly larger than in the CB6 and T.Empty samples, which had a small number of genes. (p<0.05) (Fig. 13B). Genes characteristic of activated microglia and reactive astrocytes (Table 2). None of the genes showed significant changes in the CB6 and T.Empty samples. Ta.

[0172] [Example 6] Therapeutic effects of different AAVrh8 vectors in GM1 gangliosidosis mice The above, βgal + / - Studies conducted in mice have shown that The reduction in protein expression reduces the pathological changes in transcription levels within the injected structures. We then determined the correlation between the ability of AAV vector design to target GM1 ganglionic acid and the ability to target GM1 ganglionic acid. Osidotic mice (βgal - / - ) led to differences in treatment outcomes We investigated the effects of βgal on the 6- to 8-week-old - / - AAV vectors were injected into mice into the thalamus (hematological Bilateral injections were given into the cerebellar nuclei (1 μl per side) and deep cerebellar nuclei (0.3 μl per side). Outcomes were measured approximately 6 weeks after the study. The study cohort consisted of 4.4 × 10 9 vg total dose CBA-WPRE, CB6 (low dose CB6), and empty transgene injected with vector, βgal - / - In addition, CB6 was added to the mice at 2.6 × 1 0 10 The total dose of βgal was 100 mg / kg (high dose CB6). - / - Animals and naive untreated βgal + / +The animals were used as controls. Assessment of βgal activity by MU assay (Fig. 14) showed that CBA-WPRE inhibited βgal activity in the brain. , 45-fold higher than wild-type levels (Fig. 14), whereas low-dose CB6 was 9-fold higher (Fig. 1 4), high dose CB6 showed a 30-fold increase in βga (Figure 14). l - / - The T.Empty and untreated cohorts of mice were not affected by any of the analyzed CNs. Even within the S region, there was no detectable β-gal activity (Fig. 14). The CBA-WPRE expression levels were 47-fold higher than the wild-type level (Fig. 14), and the low dose CB6 was 6-fold (Figure 14), and high-dose CB6 was 27-fold (Figure 14). Unfortunately, in the spinal cord, CBA-WPRE was only 50% of wild-type levels (Fig. 14). The high dose CB6 was 30% (Figure 14), and the low dose CB6 had no detectable activity. In all CNS tissues analyzed, high dose CB6 reduced β-gal activity and significantly higher than the same vector, low-dose CB6 (p<0.001). It was big.

[0173] The distribution pattern of β-gal in the brain, as confirmed by the histological dye X-gal (Fig. 15) was determined by the 4-Mu assay, and activity levels in the cerebrum or cerebellum plus brainstem were The CBA-WPRE vector increased the dark blue staining in the thalamus and DCN (Fig. 14). This resulted in widespread distribution of color and detectable enzyme activity throughout the brain. (Fig. 15A). In contrast, the low-dose CB6 cohort (Fig. 15B) showed intrathalamic and DC Intense staining was observed within the N, but no detectable levels were observed throughout the cerebrum, cerebellum, or brainstem. In high-dose CB6 animals, the brain distribution pattern of β-gal was low. The distribution pattern in the brain appeared more widespread in CB6 animals (Fig. 15C). As expected, the T.Empty cohort (Figure 15D) and naive βgal - / - In the mouse cohort (FIG. 15E), there was no evidence of increased βgal activity.

[0174] Histology for lysosomal accumulation in the brain and spinal cord using filipin staining The biological analysis (Fig. 16) confirmed the βgal activity (Fig. 14) and distribution pattern ( In CBA-WPRE-injected animals, the injection site and route were not significantly different. Near-complete clearance of accumulation was observed throughout the brain (Fig. 16), but not within the ventral hippocampus. , and filipin-positive cells were observed throughout the thalamus (Figure 16; row 1, column 4). Filipin-positive cells were detected in the anterior cingulate cortex, striatum, and brainstem (Fig. 16; respectively). row 2, columns 2, 5, and 7), suggesting a clear accumulation in the low-dose CB6 cohort. The effect of CB6 on the steroid hormone was considered to be low (Figure 16; row 2). The efficiency of the CB6 vector is extremely high, and the dissipation of lysosomal accumulation is widespread throughout the brain. As before, filipin-positive cells were detected in the ventral hippocampus and dorsal visual cortex (Fig. 16; row 3). Although it was present in the bed, it was low in CBA-WPRE (Figure 16; 3rd row, 1st, 4th The T.Empty cohort (Figure 16, row 4) showed a significant increase in lysosomal accumulation of βgal - / - No changes were observed compared to the untreated control (Figure 16; row 5).

[0175] The spinal cords of AAV-treated animals were also assessed for accumulation content by filipin staining. The spinal cord in BA-WPRE animals showed almost no accumulation in the cervical region, but the thoracic region Only the area where the CB6 activity was decreased was slightly reduced (Figures 17A-17B; arrows). The spinal cord in the control group showed almost no discernible reduction in accumulation compared to untreated controls. The spinal cord in high-dose CB6 animals showed a significant increase in the cervical and thoracic regions (Figures 17C-17D). The accumulation of lysosomes within the nuclei was largely absent (Figures 17E-17F; arrows). The spinal cord of T.Empty animals shows lysosomal accumulation of untreated βgal - / - Compared to the control No significant changes were observed (Figs. 17G-17H; 17I-17J, respectively).

[0176] GM1 ganglioside levels in the CNS were quantified by LC-MS / MS (Figure 18 ) in the CBA-WPRE cohort and the low-dose CB6 cohort, cerebral (p = 0.0009 and p=0.002) and cerebellum+brainstem (p<0.0001 and p<0.0002, respectively). and p=0.0001) of GM1 ganglioside content in untreated βgal - / - In the spinal cord, GM1 gas was significantly reduced in both cohorts compared to controls. No significant changes in guanosine glioside content were observed in the high-dose CB6 cohort. Glycoside levels were measured in all CNS regions investigated: cerebrum, cerebellum + brainstem, and spinal cord. (Figure 18; p=0.64, p=0.06, and p=0.001, respectively) 79). As expected, in the T.Empty cohort, no significant changes were observed in any region of the CNS. The GM1 ganglioside content of the native βgal - / - Changes compared to the control were observed (Figure 18).

[0177] [Example 7] AAV-mediated transmission to the CNS in an animal model for GM2 gangliosidosis gene delivery Prior to conducting clinical trials in patients with Tay-Sachs disease, final studies were conducted in non-human primates. This study evaluated the safety of AAVrh8 vector formulations in the thalamus and unilateral brain. A single study with different endpoints to support the safety of the injection procedure consisting of bilateral injections into the ventricles 3.2 × 10 doses (based on previous studies in GM2 mice and GM2 cats) 12 v The study was designed to be a 200-day (1000-2000 mg / kg total vector dose) study.

[0178] First, NHPs (N=3) injected with the AAVrh8 formulation showed a median age of 14 days after injection. The NHPs developed mild to severe neurological symptoms. The NHPs were euthanized, and CNS histology was performed. Clinical evaluation revealed large, necrotic areas and lesions within the thalamus along the area of ​​the suspected injection route. In contrast, the injection of saline revealed areas of myelin loss (Fig. 22A-22D). Injected NHPs showed no symptoms and no evidence of neuropathology at necropsy (>90 days post-injection). In addition to histopathological evaluation of the brain, hexosaminidase was also detected. The enzyme activity was measured to be 6 to 48 times higher than normal activity (Figure 24).

[0179] Two additional cohorts of NHPs (N=2 per cohort) were administered AAVrh8 The vector formulations were administered at 1 / 10 and 1 / 30 of the original dose, respectively, for a total dose of 2 × 1 0 11 vg and 1.1 × 10 11 vg. In 3 of 4 NHPs injected with AAVrh8 vector formulations expressing the subunit, Neurological symptoms developed, but the onset was progressively delayed with decreasing dose. Despite the delayed onset of symptoms (or, in one NHP, the absence of obvious symptoms), Neuropathological evaluation of the brain revealed no significant differences in all four NHPs in the low-dose cohort. , revealing widespread necrosis, nerve loss, and cell infiltration into blood vessels (Figure 22 E) In these NHPs, brain hexosaminidase activity was also significantly increased by saline injection. Hexosaminidase activity was elevated compared to that in animals with Hex expression (Figure 23). Increases were also found in the spinal cord, which were more pronounced in the 1x dose animals. (Figure 23, descending row).

[0180] Control for potential toxicity associated with the AAVrh8 capsid and / or preparation method In another cohort of NHPs (N = 2), 3.2 × 10 12 vg, transgene received empty AAVrh8 vector, none of the animals showed any signs of aging throughout the study (>10 days post-injection). All animals in the study exhibited normal behavior. , summarized in Table 3.

[0181] Prior to autopsy, brain MRI was performed on some NHPs in the low-dose cohort. In the thalamus, bilateral signal changes were found, possibly due to edema (ascending, Fig. 24), but no changes were observed in NHPs injected with the AAVrh8 vector containing an empty transgene. None was observed (lower row, Figure 24).

[0182] In addition to neuronal loss within the thalamus along the injection route, intracellular eosinophil granules were also observed in the vicinity. Large, dense neuronal fields were also observed (Fig. 25E, 25G), which are similar to those in other parts of the brain. No significant changes were evident within the region (Fig. 25F). Hexosaminidase alpha subunit Alternatively, immunofluorescence staining with an antibody specific for the hexosaminidase beta subunit revealed These granules likely contain these two proteins ( These cells, loaded with HexA subunit-positive granules, were found in the thalamus. This correlates with the findings in the H&E stained sections. These observations reveal intralysosomal accumulation of the protein in several tissues. findings in a GUSB transgenic mouse model (Vogler et al., 2003) It brings to mind...

[0183] Two key observations emerged from this safety study in normal young NHPs: first, many The thalamic regions containing HexA-positive neurons were not associated with evidence of significant inflammatory infiltrates. Although the lesion appears intact (Figs. 25E and 25G), there is extensive nerve loss along the injection route. and inflammation (Figure 22), and secondly, the transgene-empty AAV at the highest dose. It has been observed that there is no evidence of toxicity associated with the rh8 vector. As a result, neurotoxicity in NHP brains after AAVrh8-HexA-mediated gene transfer Massive overexpression of HexA in AAVrh8-transduced thalamic neurons This is caused by a β-amyloid β-amyloid complex, which, above an unknown threshold, induces cell death and secondary neuritis. It is thought that this may result in an inflammatory response (such as cell infiltration into blood vessels).

[0184] [Table 3]

[0185] [Example 8] The new AAV vector plasmid (Figure 26) was transiently transfected into 293T cells. The expression level of the hexosaminidase (Hex) enzyme was examined during the cleavage. Two examples are shown in Figures 27 and 28.

[0186] The original AAV vector plasmid pair (pAAV-CBA-CI-W delta6ATG) The promoterless AAV vector plus produced the highest level of Hex activity. plasmid (pAAV-NoP), or an AAV vector plasmid without a transgene (empty transgene) into Hex-active, naive, untransfected 293T cells. In contrast, other AAV vector plasmids did not result in a detectable increase in the expression of the vector (Figure 29). The six test AAV vector pairs resulted in a gradient of Hex activity. Two AAV vector controls (a promoterless control, For in vivo studies, the transgene-free control was selected. A total of 15 vector strains were generated (Table 4).

[0187] AAV vectors were transfected into 10-12 week old male athymic nude mice (Charles Ri ver Labs) into the thalamus and left lateral ventricle on both sides, 1.32 × 10 10 Be The control group was injected with a total dose of promoterless AAV vector (vg). vector formulation (AAV-NoP), AAV vector without a transgene (empty transgene), mice injected with phosphate-buffered saline (PBS), and finally, mice injected with non- Injected mice (N=8 for all experimental and control groups) were included (Table 4). , biochemical analysis for Hex expression, and histological studies were performed 1 month after injection. All groups exhibited the same increase in mean body weight over the course of the experiment (Figure 30). The animals were euthanized due to significant weight loss and the development of neurological symptoms. Unlike the preliminary experiments with the higher doses, there was no evidence of significant behavioral changes during this period. The dose used in this study (1.32 × 10 10 vg) indicates all test items For quality and control, to normalize the total vector dose, one of the vector pairs Determined by the lowest titer.

[0188] Hex activity was measured using the artificial substrates MUG (Figure 36) and MUGS (Figure 37). Measurements were taken in four coronal cerebral blocks, the cerebellum, the brainstem, and the spinal cord. The Hex activity in coronal cerebral blocks containing the serotonin A and serotonin B is shown in Table 4, and the findings are summarized. The original AAV vector pair (group 1) produced 400-1,700 times higher Hex activity than normal. Similar to the results in cell culture, other AAV vector pairs were shown to be more potent than the original AAV vector in the brain. The 1 / 3 (Group 2), 1 / 20-1 / 30 (Group 4), and 50-10 times smaller (Group 5) of the turpentine formulation (Group 1) were used. 0-fold lower Hex activity (group 6), demonstrating the activity of AAV-mediated Hex expression in the brain. The other AAV vector pairs (groups 3 and 5) yielded a 1-2 log range of responses. It did not result in Hex activity above the normal levels present in the brain of athymic nude mice. The control groups (groups 7, 8, and 9) showed no significant changes in Hex activity.

[0189] Neuropathological examination of the brain revealed numerous eosinophilic granule-containing tumors in Group 1 animals. This finding was consistent with the AAV vector used in Group 1. Although the number of these abnormal neurons was identical to that observed in the ct-injected monkeys, In mice, the spleen size was significantly smaller than in monkeys. This observation was also observed in Group 2 animals. Although the number of abnormal neurons was significantly smaller than that of group 1 (Fig. 31L). Neurons were also observed in the hippocampus of group 2 animals (Fig. 31B). , which was not observed in any other animal group. Immunofluorescence staining with antibodies showed that the IgG4-dependent markers were significantly different in groups 1 (Fig. 31A, 31K), 2 (Fig. 31B, 31L), and 4 (Fig. 31C). 31D, 31N), and 6 (Fig. 31F, 31P) animals in the hippocampus and thalamus. In the control group, a large number of enzyme-expressing cells were found. The antibody species used in this study detects the monkey enzyme but not the mouse protein. Due to specificity, no evidence of Hex-alpha subunit expression was seen.

[0190] Intrahippocampal and intracellular signals in animals injected with the original AAV vector formulation (Group 1) (Figures 33A, 33K) and in the thalamus, Iba-1 staining (microglial activation) was significantly higher than in the control (Fig. 33I, 33J). We observed a dramatic increase in microglial activation compared to the control group (33S, 33T). This evidence is based on the localization of HexA-positive cells to the site detected by immunofluorescence staining. (Fig. 32A, 32K), no obvious changes in microglia were observed elsewhere in the brain. In groups 2 and 3, the increase in Iba-1 staining in the hippocampus and thalamus was very weak (Fig. 33B-33C, 33L-33M) and were essentially indistinguishable from controls in groups 4-7. (Figures 33D-33G; 33N-33Q).

[0191] Using GFAP immunostaining, brains were also examined for evidence of reactive astrogliosis. In the hippocampus, evidence of reactive astrogliosis was also observed in the original AA This was found only in animals injected with the V vector formulation (Group 1) (Figure 34A). All animals were indistinguishable from controls. In the thalamus, some ascites were observed in groups 1-3. Trogliosis was observed (Figs. 34K-34M), but was either weak or clustered. The levels were considered indistinguishable from the control within 4 to 7 (Figs. 34N to 34Q). No other brain regions in the group showed evidence of astrogliosis.

[0192] Two new AAV vectors (Figure 35) were identified: AAV-CB6-I-cmHex (sequence number 1111111); promoter represented by sequence number 4), and AAVP2-I-cmHex (SEQ ID NO: 5, construct represented by SEQ ID NO: 6) were added prior to the start of the experiment. All of the study criteria defined herein (absence of significant behavioral changes, control group and whether the body weight remained stable between 0 and 30 days after injection. The presence of neuropathology and the presence of thalamic and rostral non-injection blocks were associated with increased These new AAV vector formulations (group 4 and 6) have demonstrated that increased Hex expression in the brain compared to controls is evidence of neuropathological changes. with little or no evidence of eosinophilic neurons, microgliosis, or (absence of astrogliosis).

[0193] From the original AAV vector, the wpre element has been removed, but the expression element ( The promoter and artificial intron) are still the same in the new AAV-CBA-I The -cmHex vector (Figure 35) was also investigated. This AAV vector (Group 2) , approximately one-third of the Hex activity level compared to the original AAV vector, and A long-term study in Sandhoff mice showed a reduction in microgliosis compared to control mice. in the AAV vectors used in the study and in the long-term study in Sandhoff cats. Considering that the expression elements are the same in the AAV vector and the V vector, It is also possible that the reduction in Hex expression levels may mediate long-term expression. Given the attenuation of the activation of the α-amyloid β-amyloid complex, this new AAV vector is suitable for the experiments in Example 9. , dose (3×10 11 vg) and duration significantly affected the behavior of NHPs. There is little chance of this happening.

[0194] [Table 4]

[0195] [Example 9] In athymic nude mice, the expression of beta-hexosaminidase in the brain was evaluated by the original AA Increased inflammatory response (astrogliosis and microgliosis) compared to V vector preparations Three AAV vector designs (Figures 19 and 35) were developed to mitigate the effects of HIV-1 and HIV-2. The AAVrh8 vector was selected in the absence or presence of neutralizing antibodies against the AAVrh8 capsid. or into NHPs screened for very low titers (Table 5).

[0196] 3.2×10 11 The total dose of vg was administered bilaterally to the thalamus (50% dose; 2 × 150 μ The vector formulation was also injected into the left lateral ventricle (50% dose in 300 μl). Immediately after injection, targeting accuracy and distribution in the brain were determined by MRI. The endoscopic procedure also contained 2 mM gadolinium (Figure 38A). All NHPs tolerated the procedure well. The mean volume of distribution of gadolinium in the thalamus (Vd) was The injection volume in the thalamus (Vi) was 0.3 mL (Figure 38B). mL, this corresponds to a Vd / Vi ratio of 4.9.

[0197] The behavior of all six NHPs injected with AAVrh8 was consistent throughout the 90-day study. As planned, brain MRI was performed monthly (Figure 39). From day 30 onwards, Signal changes at the injection site were recorded in two monkeys from cohorts 2 and 3. However, no significant changes were observed over time (Figs. 40B and 40C). In one monkey in Study 1, brain MRI at 30 and 60 days after injection showed no significant changes in the signal intensity. On day 90, no significant signal changes were observed in the left thalamus. Despite this abnormal signal, the behavior of this monkey at 90 days was Movement remained constant throughout the study.

[0198] Brains were cut into 4 mm coronal blocks and assayed for hexosaminidase (Hex) activity. The enzyme distribution maps were used to assess neuropathology. A biopsy punch (3 mm diameter) was used to sample the brain to create (Figure 41). In all cohorts, there was above-normal total Hex activity only within the thalamic punch. The genotypes (HexA, HexB, and HexS) were detected (Table 6). ex activity was highest in cohort 1 (up to 87 times normal) and in cohorts 2 and 3 The results are consistent with those in athymic nude mice. Total Hex activity in most other brain regions sampled was comparable to that in uninjected control monkeys. The total Hex activity was similar to that of the control.

[0199] Neuropathological assessment of the brain revealed intraneuronal eosinophilic material in monkeys in cohort 1. In animals in cohort 1, moderate to severe symptoms were observed. In cohort 1, one monkey (ID: 295851) showed severe neurodegeneration in the left optic nerve. In the bed, severe focal spongiosis and perivascular cellular infiltration were observed (Figures 43A and 43B ) This lesion was observed in the left thalamus of one monkey in cohort 1 90 days after injection. This corresponded to the abnormal MRI signal that was evident (Figure 40A).

[0200] In cohort 2, no accumulation of eosinophilic material was observed, and rare neurodegenerative and satellite lesions were observed. Focal inflammation in the white matter, accompanied by neurodegeneration, likely associated with injection site / tract trauma was observed in one monkey (ID: 295847).

[0201] In cohort 3, no accumulation of intraneuronal eosinophilic material was observed, and rare neurodegenerative and satellite diseases were observed. In one monkey (ID: 295709), cannulation and Foci of perivascular lattice cells were seen, likely associated with the lesions (Fig. 44B). eosinophilic material accumulation in the nerve (Fig. 45), nerve degeneration and necrosis (Fig. 46), as well as For quantification of inflammation (Figure 47), the left thalamus and Serial sections were prepared at 150 μm intervals throughout the right and left thalamus. cohort showed significant neurodegeneration, necrosis, spongiosis, and corresponding inflammation. With the exception of one animal at the left injection site, formulations 1 and 3 significantly increased intracerebral These findings were consistent with the 90-day brain MRI and the The best fit was obtained (Figure 40A).

[0202] The new vector, AAVrh8-CBA-cmHex (Figure 19), and AAV rh8-CB-I-cmHex (Figure 19) inhibits Sandhoff disease ( A small pilot study was conducted to determine the effectiveness of reducing GM2 content in the CNS of SD. All previous studies in SD mice and SD cats have shown that this vector Since the original AAVrh8-CBA-cmHex-W Δ6ATG Vectors, The AAV vector was administered to 4-6 week-old SD mice in both the thyroid and thyroid glands. 4.68 × 10 per mouse into the thalamus and left lateral ventricle 9 A total dose of vg was injected. Therapeutic efficacy in SD mice injected with the original AAVrh8-CBA-Hex-W vector In efficacy studies, this was the test dose. Total Hex activity in the thalamus of NHPs treated with AAVrh8-CB Approximately 1 in 20 of the NHPs injected with A-cmHex (cohort 1 in Table 6) Therefore, a 5x higher dose (5x dose: 2.34 x 1010 vg), AAVrh8-CB- An additional cohort of SD mice injected with the I-cmHex vector was also enrolled. To measure Hex activity as well as GM2 ganglioside content, 1 month after injection, Mice were sacrificed and the brains were divided into four coronal blocks of approximately 2 mm each (Figure 48). Vrh8-CBA-cmHex-W Δ6ATG (green bar, Figure 48), and AAVrh8 -CBA-cmHex vector (orange bar, Figure 48) in one of three SD mice injected In the AAVrh8-CB-I-cmHex vector, hexosaminidase was undetectable. In mice injected with acetaminophen (blue bars in Figure 12), the 1x and 5x cohorts showed significant differences. Hex activity was not detected in 3 of 3 and 2 of 4 animals, respectively, within the study. In a comparative study in athymic nude (nu / nu) mice, the SD mice of this example In some cases, the AAVrh8 vector tested in this study exceeded normal levels by 2-3 orders of magnitude. This resulted in significant Hex overexpression in a subset of SD mice. The lack of Hex expression may limit enzyme distribution via a humoral response or adaptive response. Cynomolgus monkey Hexalin mediated by α-glucan, resulting in loss of transduced cells Immunization against the fa (A) subunit or the cynomolgus monkey Hex beta (B) subunit Although the number of mice per group was small, the Hex activity was There appears to be a direct correlation between the sex level and the reduction of GM2 ganglioside. Block 3 contains AAVrh8-CBA-cmHex-W Δ6ATG Note vector In SD mice injected with α-glucan, a maximum 96% reduction in GM2 ganglioside content was observed. For AAVrh8-CBA-cmHex, a 92% reduction was observed, and injection of 1x and 5x doses of Vrh8-CB-I-cmHex vector, respectively. In mice treated with IFN-γ, a 42% and 85% reduction was observed.

[0205] [Example 10] Simultaneous expression of the transgene of interest in both neurons and astrocytes, respectively. For efficient dual expression, the human synapsin 1 (also referred to as "Syn1") promoter was used. and the human GfaABC1D (also called "GFAP") promoter. We constructed an AAV vector carrying Syn1-GFP-2×miR. SOD1 / GFAP- 2×miR SOD1 The vector, called -mCherry, targets synapsins in neurons. GFP driven by the GFAP promoter in astrocytes. Two anti-SOD1mi antibodies encoding human SOD1 and mCherry, which are transduced with SOD1. The RNA contains the final codon and polyadenylation signal of each of GFP and mCherry. The vector uses the AAV9 capsid protein. In some embodiments, the vector, Syn1- GFP-2×miR SOD1 / GFAP-2×miR SOD1 -mCherry sequence Represented by the number 12.

[0206] The transduction profile of the dual promoter vector AAV9-Sy was investigated. n1-GFP-2×miR SOD1 / GFAP-2×miR SOD1 -mCherry , SOD1 G93A Intrastriatal injections were performed into adult mice and fluorescence microscopy was performed. The shapes of GFP (green) and mCherry (red) expressing cells are different from each other. This indicates that the shape of the cells corresponds to that of neurons and astrocytes (Figure 51).

[0207] SOD1 mRNA expression was measured. Data were obtained using the dual promoter AAV9 -Syn1-GFP-2×miRSOD1 / GFAP-2×miRSOD1-mCher After injection of the ry vector, adult SOD1 G93A Human SOD1 mRNA in mice This indicates that the NA level is reduced (Figure 52). 12 of the whole vector genome After intravenous injection, it reduced human SOD1 mRNA expression in the spinal cord by up to 25%. Observed. 8×10 9 After direct intrastriatal injection of the whole vector genome, A maximum 55% reduction in human SOD1 mRNA expression was observed.

[0208] The data demonstrate that this dual promoter construct is ubiquitous while reducing toxicity to non-CNS tissues. This is larger and more widespread than current approaches that use heterologous promoters (e.g., CBA, U6). Resulting in transduction of specific cell types (e.g., neurons and astrocytes) within the NS It points to what will be brought about.

[0209] [Example 11] Combined intrathalamic (TH) and deep cerebellar nucleus (DCN) injections (TH / DCN), or bilateral intrathalamic injections combined with a single intracerebroventricular injection (TH / ICV). rAAVrh encoding the hexosaminidase A subunit was synthesized through two methods. 8 and rAAVrh8 encoding the hexosaminidase B subunit (respectively, 1:1 formulations (columns 20 and 21) were intracranially injected into 4-week-old SD mice. Vrh8-treated SD mice (4.68 × 10 9 vg), and controls (untreated SD littermates and Behavioral performance of the mice (and wild-type littermates) was assessed over time, starting at 60 days of age (1 month after injection). The effect of TH / ICV AAVrh on the survival of mice at 120 days of age (P≦0.05) was evaluated (FIG. 53). The performance of SD mice treated with 9 on the inverted screen was significantly better than that of untreated SD mice. TH / ICV AAVrh8-treated mice at 180 days of age, and The performance of both TH / DCN AAVrh8-treated mice was comparable to that of wild-type controls. The results were comparable (Fig. 53A). The rotarod test also showed that AAVrh8 mice at 120 days of age Both cohorts of SD mice treated with α-glucan-1-phosphate dehydrogenase (α-glucan-1) performed better than untreated SD controls (P≦0.01). .01), and their performance was comparable to that of wild-type controls up to at least 180 days of age. In the wire hanging test, the treated SD mice showed significant improvement compared to the untreated SD mice. Not measured (Figure 53C). TH / DCN or TH / ICV resulted in 4.68 x 10 9 SD mice treated with the vg dose survived for 424 and 423 days, respectively. The median value was 1.07 (Figure 53D). Therefore, both intracranial delivery methods were Compared with TH / DCN, similar lifespan extension (P ≤ 0.001 for TH / IC V, P ≤ 0.0001) and were not significantly different from each other. (P>0.05).

[0210] Whether increasing the dose of AAVrh8 further extends survival in SD mice A dose-escalation study was conducted to determine the intracranial TH efficacy of AAVrh-mHexA / B. SD mice were injected with AAV8-TRG-mHexB (3 × 10 11 vg) were intravenously injected. AAV8-TBG-mHexB systemic injection alone was administered to SD mice. did not enhance survival of the untreated SD mice (median survival was 127 days for untreated SD mice). whereas median survival for SD mice treated with AAV8-TBG-mHexB was The mean value was 128.5 days (Figs. 53D and 54A). Systemic therapy-mediated tolerability improved median survival by 4.68 × 10 8 skull in vg The combination therapy did not significantly enhance survival compared with intravenous delivery alone (median survival was 448.5 years). The median survival with TH / ICV alone was 423 days; Figures 53D and 5 4A). The same tolerization protocol (AAVrh8-mHexA / B vector) delivered intravenously. AAV8-TBG (mHexB) in combination with HIV-1 / HIV-2 (mHexB) prior to TH / ICV delivery of the vector. In addition, dose escalation of intracranially delivered AAV (4.68 × 10 7 vg, 4.68×10 8 vg , 4.68×10 9 vg, 1.17 × 10 10 vg) at the two highest doses This resulted in an extension of (4.68×10 9vg and 1.17 × 10 10 vg, P ≤ 0.0001; median survival of SD mice treated systemically alone was 128.5 days. Yes; 4.68 x 10 7 : 110.5 days, 4.68 x 10 8 vg: 135 days, 4.6 8×10 9 vg: 448.5 days, 1.17 × 10 10 vg: 591 days; Fig. 5 4A). Despite maximum survival of 666 days, the high dose (1.17 × 10 10 vg dose ) Treated animals ultimately presented with hind limb weakness and ataxia at the time of euthanasia, with some animals Loss of weight bearing and / or ability to stand upright when placed supine.

[0211] Inverted screen performance (Figure 54B), rotarod performance (Figure 54C), or wire-hugging At 120 days of age, 4.68 x 10 9 vg or 1.17 x 10 10 vg (intracranial TH / ICV administration) dose-escalating combination therapy mice There was no significant difference in behavioral performance compared to untreated SD mice. AVrh8-treated SD mice retained their motor function and were significantly more active than TH / ICV-treated SD mice at 180 days of age. SD mice performed comparable to wild-type mice in reversal screen performance at all doses. At 180 days of age, TH / ICV-treated SD at any dose also showed a significant improvement (Fig. 54B). Mice also performed comparable to wild-type mice on the rotarod (Fig. 54C). In the Yahang test, no significant improvement was measured compared to intracranially untreated SD mice (Figure 1). 54D), which was close to the median survival age of untreated SD mice (120 days). Further studies will be performed at 180 days of age, when no untreated SD mice survive. I was able to do it.

[0212] Potential effects of intracranial injection of AAVrh8 vectors in the absence of underlying neurodegenerative processes Age-matched heterozygous (HZ) littermates (HexB + / - ) mouse, 4.68 × 10 9 Intracranial injection of vg of AAVrh8 vector formulation The AAVrh8-treated HZ mice and non-treated HZ mice were administered TH / ICV or TH / DCN. Treated controls (wild type and HZ) are evaluated over a time course in different behavioral tests. In AAVrh8-injected HZ mice, there was a clear improvement in behavior compared to controls (Fig. 55). No major changes or effects on survival were observed. However, no differences between the cohorts were apparent (Fig. 55A). Performance was slightly superior to untreated HZ and wild-type controls in the rotarod test at 180 days of age. The results of wire hanging were significantly poorer at either 60 or 120 days of age (Fig. 55B). In this case, no significant difference was observed between the cohorts (Figure 55C). In this study, the performance of TH / DCN-injected HZ mice was significantly higher than that of untreated HZ animals (P ≤ 0.05) and non-treated HZ animals (P ≤ 0.05). At 180 days of age, TH / ICV injection was significantly worse than that in treated wild-type animals (P≦0.01). No significant differences were observed in the performance of the animals compared to untreated HZ or wild-type animals.

[0213] The content of GM2 ganglioside and expression of hexosaminidase in the CNS were analyzed by TH / ICV AAVrh8-treated (1.17 × 1010 vg) SD mice, untreated SD mice, and untreated wild-type controls (Figure 56). G measured by LC-MS / MS M2 ganglioside was not detected in the cerebrum of AAVrh8-treated animals, but in the cerebellum (91.1 %, brainstem (99.6%), and spinal cord (99.8%) also showed the presence of GM2 ganglioside. A significant reduction in the expression of IFN-γ was observed in AAVrh8-treated SD mice (P≦0.0001, Figure 56A). In the central nervous system, total hexosaminidase activity was restored. , exceeded wild type and were comparable in the cerebellum, brainstem, and spinal cord. When subjected to routine endpoints equivalent to those of D mice, they were indistinguishable from wild-type controls ( data not shown).

[0214] [Example 12] All SD cat experiments were performed using the vector constructs (AAVrh) used for human application. 8-CB-CI-hHexA / B), which is slightly different from AAVrh8-CBA-mHex A / B-WPRE was used to conduct treatment efficacy studies in patients with rapidly progressing disease and a median survival of 4 years. These studies were conducted in a naturally occurring Sprague-Dawley cat model, with the cats being aged 0.3±0.2 months. In this study, the hexosaminidase alpha subunit and the hexosaminidase alpha subunit of wild-type cats were 1 by two AAVrh8 vectors encoding the zeta subunit and the zeta subunit separately: One formulation was used.

[0215] In this example, long-term therapeutic efficacy data are reported. SD cats were treated with unilateral ICV injection (ICV ; n = 5) combined with bilateral intrathalamic injections resulted in 4.6 × 10 11 vg total dose (both The ratio of the vector to the gene was 1:1 (Table 7). The survival time was significantly increased (p<0.0001; Figure 57A), with the oldest cat living to 29.9 months of age. Untreated SD cats showed severe tremors with pronounced generalized rest and intention tremors. suffered from brain disease, which was accompanied by loss of locomotion and subsequent euthanasia at approximately 4 months of age. After AAV gene therapy, significant improvement in neurological symptoms was observed ( (Figure 57B). Tremors were completely resolved in all treated cats, with the majority remaining stable over the course of the study. Throughout the study, the ability to walk was preserved, and the musculoskeletal disease was not a typical neurological phenotype in SD cats. All animals were euthanized due to gastrointestinal or respiratory illness (Table 7).

[0216] [Table 7]

[0217] Both ICV injections and combined intrathalamic injections (Th+ICV) of AAV vectors , resulting in widespread hexosaminidase distribution throughout the cerebral cortex, cerebellum, and spinal cord. (Figures 57B and 57C). The only area of ​​the brain where it is less distributed is the temporal lobe. The HexA levels were significantly higher in the brain than in the control group (Figure 57D, lateral view of Figure 57D, and Figure 57E). , cerebellum, and spinal cord, were near or above normal, and In AAV-treated cats, the increase in Hex was nearly 50 times higher than normal (Fig. 57E). No histopathological abnormalities were observed despite supraphysiological levels at the site. I couldn't.

[0218] MRI (T2W) at the humane endpoint in SD cats showed whole-brain, cerebrospinal fluid, and cerebrospinal fluid. Darkening of the white matter (accumulation of GM2) and lightening of the white matter (demyelination) are shown (Figure 58A). After V gene therapy, gray and white matter intensity throughout the brain, with the exception of the temporal lobe A normalization of the distribution of Hex was observed, which was thought to be due to a decrease in the distribution of Hex (Figure 58D). Despite normalization of cerebral and white matter intensity, AAV-treated SD cats showed significant increases in the lateral ventricles and Cortical atrophy persisted, as exemplified by increased CSF in the pericerebral sulci and pericerebral cortex. Using MR spectroscopy, we identified a number of thalamic sites in untreated SD cats, including those in mice and humans with SD. In this study, the previously reported toxic metabolite, N-acetylhexosamine (NA-H), After AAV gene therapy, a significant increase in NA-Hex was detected in all cats. In AAV-treated cats, the HexA level was completely reduced to normal levels (Fig. 58B). The level of HexA is elevated at or above normal levels, and elevated HexA is associated with a lifetime The effect persisted throughout the cytotoxic period (Fig. 58D). Transferase and lactate dehydrogenase were elevated in the CSF of SD cats, After AAV gene therapy, the levels of these enzymes returned to normal (Figures 58D and 58E Serum antibody titers against the capsid were present for 1-2 months after treatment, but did not decrease over time. The humane endpoint was reached before age 1 year. Only one cat (11-907) had a maximum serum antibody titer of 1:6 approximately 2 months after treatment. The endpoint titer was only 1:16 (Figure 58G). A cat (7-760) that lived to 6 months of age had a maximum titer of 1:16 3.6 months after surgery. Due to the limited number of vector strains, it was not possible to analyze all time points. However, after approximately 20 months of treatment, serum titers decreased to 1:1 (Figure 5 8H).

[0219] Despite CNS-directed delivery of AAV, SD+AAV TH / ICV cats showed peripheral HexA enzyme activity in the organs was increased. The sciatic nerve showed a 203% increase over normal. whereas normal liver and muscle showed increases to 53 and 20% of normal. (Table 8).

[0220] [Table 8]

[0221] In this study, we investigated the chicken beta-actin (CBA) promoter and the woodchuck transcription factor (WTF) Encoding feline HEXA or feline HEXB, flanked by a post-regulatory element (WPRE) AAVrh8 delivery of two monocistronic vectors was investigated. Intracisternal injection (6.4×10 11 vg, approximately 0.5 kg at the time of injection) and A subset of subjects (n=3) was euthanized 16 weeks after treatment and assessed for biodistribution. A second cohort (n=2) was followed to a humane endpoint. He suffered from severe cerebellar disease, manifested by a progressively debilitating, generalized resting tremor and The animals were diagnosed with tremors and intention tremors, loss of ambulation, and subsequent euthanasia at approximately 4.4 ± 0.6 months of age. AAV gene therapy via intracisternal injection (SD+AAV CM) Treated SD cats had a similar humane endpoint to untreated SD cats. At time point, 16 weeks after treatment, there were minor neurological signs, including staggered gait and mild hind limb weakness. Two cats followed to a humane endpoint had a 9.9% mortality rate (Figure 59B). They survived to ±0.5 months of age and retained the ability to stand and walk, but were unable to respond to visual or auditory stimuli. It was unresponsive to stimulation.

[0222] The biodistribution of Hex in SD+AAV CM cats was observed throughout the spinal cord and cerebellum. The cerebral cortex was occluded and widespread, but was reduced within the protocerebral regions (Figs. 59C, 59D, 59E). Short-term treatment of SD cats (data not shown) and long-term treatment of SD cats with SD+AAV CM In cats, hexosaminidase A (HexA) activity is normal in the cerebellum and spinal cord. reached or exceeded normal levels, but included the rostral thalamus, striatum, and frontal cortex. In the blocks with cerebral infarction (brain blocks D to A, respectively), the results were comparable to those of untreated cats. The biodistribution of the steroid showed a similar trend, with brain block D (the most anterior analyzed block) showing a similar distribution. contained the lowest vg copy number (Fig. 59F), but qPCR showed that the He x expression differences.

[0223] Accumulation in SD cats was assessed using periodic acid staining, which stains for glycolipids (e.g., GM2). The area is shown by PAS (gray scale) staining. Dark staining areas, e.g., PAS positive, In SD cats, the PAS region in the gray matter shows increased accumulation of gangliosides. There was increased staining and decreased staining in the white matter, which may be due to gangliosides within the cell bodies. In SD+AAV CM cats (long-term), accumulation and clearance of steroids were observed. The effect of Hex on the body distribution was inversely reflected by its efficacy in the spinal cord and cerebellum, but It was not effective in the cerebral cortex. PAS-positive substances were detected in the cerebral cortex and deep brain structures. Demyelination, as indicated by a decrease in PAS-positive material, also occurred in the cerebral cortex of treated cats. Within the white matter, it was clearly represented.

[0224] The cerebellum of SD cats showed extensive neurodegeneration, evident in H&E staining ( Figure 61). Purkinje cells, deep cerebellar neurons, and brainstem neurons are severely degenerated. The patient presented with cell loss and numerous foamy, vacuolated, intracellular deposits, which are signs of Sixteen weeks after gene therapy, AAV-CM-treated SD cats showed increased activity in Purkinje cells, deep cerebellum, and The nuclei and morphology of brain stem cells were normalized (Figure 61). In treated animals, normalization of the DCN and brainstem morphology was observed, but the Purkinje cells Interestingly, the degeneration and loss of the cerebellar fastigial nucleus was prolonged in long-term AAV-treated cats. Grape-shaped eosinophilic inclusions were observed within the dorsal medial side (inset) (Figure 61). These inclusions have previously been shown to be immunopositive for Hex after intraparenchymal injection of AAV. do.

[0225] Ultra-high field MRI (7 Tesla), T2-weighted MRI, reflects the distribution of Hex. Normalization of MRI architecture in AV-treated animals is shown (Figure 62A). D In cats, there was an increase in water in the white matter (demyelination) and an increase in lipids in the gray matter (accumulation of GM2). As a result, a reversal of gray matter intensity and white matter intensity was observed. 16 weeks after intracisternal injection, MR Partial normalization of I intensity was observed, and the corpus callosum (Figure 62A; black arrow) and corona radiata (Figure 62A; white arrow) ), and cerebellar white matter (Figure 62A; black arrows) were darkened. At humane endpoint in cats, pathological intensity correlations between gray and white matter in the cerebral cortex were observed. Although the degeneration persisted, the atrophy of the cerebral cortex was alleviated, and the strength of the cerebellar white matter was partially restored (black Arrows). The thalamus (Fig. 62C), parietal cortex (Fig. 62D), and cerebellum (Fig. 62D) of an SD cat. MR spectroscopy of ) has been shown to detect the toxic metabolite, N-acetylhexosamine (NA-He). In SD+AAV CM cats after 16 weeks, NA- Hex is reduced in the thalamus (Fig. 62C) and cerebellum (Fig. 62E), but not in the humane endpoint. The parietal cortex of one SD+AAV CM long-term cat (Figure 62E) evaluated in situ. (Fig. 62D). Other metabolite changes were observed in the cerebellum after AAV treatment. of myelination (choline + phosphocholine) and metabolic activity (creatine + phosphocreatine) This endorses the partial correction of the Cr+PCr (Figure 62E).

[0226] CSF levels of HexA were above normal in all SD+AAV cats (Figure 62 F), one cat (11-1042) was 5 months of age and had a humane endpoint of C HexA activity in the CSF was rapidly attenuated. aspartate aminotransferase (AST; Figure 62G), and lactate dehydrogenase LDH (Figure 62H) was measured in one long-term SD+AAV CM cat (11-1042). In the cat (11-1148), the levels were reduced to near normal levels, but in the other cat (11-1148), the levels were moderately increased. I was forced to do it.

[0227] [Example 13] mouse Short-term biochemical analysis of the effects on GM2 ganglioside content in the CNS For the analysis, SD mice were coated with mouse HexA / B (mHexA / B) subunits. The AAVrh8-CB-CI-mHexA / B vector formulation was administered in two doses, 4. 68×10 9 vg, and 2.34 × 10 10 vg, 4.68 x 10 9 Note: vg The original AAVrh8 vector injected (AAVrh8-CBA-mHexA / B-WPRE mut6ΔATG). In the brains of SD mice injected with the / B vector, the GM2 ganglioside content was significantly higher than that of PB The highest dose (2.34 × 10 10 vg) A 92% reduction in the number of AAVrh8-CB-CI-mHexA / B vectors was observed. The reduction was comparable to that recorded in SD mice injected with the original AAVrh8 vector (97 % of the GM2 ganglioside content in the SD mice injected with PBS. A significant reduction was observed in SD mice injected with the AAVrh8-CB-CI-mHexA / B vector. It was also observed in the cerebellum and brainstem of mice, but at a lower level than the original AAVrh8 vector. The SD injected with the AAVrh8-CB-CI-mHexA / B vector showed a reduction in The extent of GM2 reduction in the CNS of mice was dose-dependent (Figure 63A). Hexo in the brain of SD mice treated with rh8-CB-CI-mHexA / B vector The saminidase activity was dose-dependent and 7-43 fold lower than that of the original AAVrh8 vector. However, the levels were still 2 to 12 times higher than normal (Fig. 63B). Survival to 1 month (exceeding the median survival of untreated SD mice) was used as the outcome measure. To investigate the therapeutic efficacy, another set of SD mice (n=8) was treated with 2.34 x10 10 vg of AAVrh8-CB-CI-mHexA / B. Most of the SD mice (6 out of 8) survived to 5 months of age. Only two of the six animals were considered to be rhesus-like (Fig. 63C). Mice presented with varying degrees of hind limb dysfunction or weakness. The new AAVrh8 vector formulation reduces the GM2 ganglioside content in the spinal cord by 20%. This can be explained by a more modest reduction compared to the BA vector (Fig. 63A; 70 35% compared to %.

[0228] To improve the effect on the accumulation of GM2 ganglioside in the spinal cord and cerebellum, The intrathalamic dose was determined as a constant (1.17 × 10 10 vg), through the lateral ventricle, The dose delivered to the SF was increased. SD mice received increased CSF doses: 1.1 7×10 10 vg, 2.34 × 10 10 vg, 5.85×10 10 vg, 5.00 x 10 11 vg of AAVrh8-CB-CI-mHexA / B were injected (per cohort) (n=3) One month after injection, the intraspinal (Fig. 64A) and intracerebellar (Fig. 64B) The reduction in GM2 ganglioside content was dose-dependent, with the highest dose (5.2 × 10 1 1 vg) is 4.68 × 10 9 vg injected with the original AAVrh8 vector and showed a similar effect.

[0229] [Example 14] Designing a compassionate use study for a single subject with Tay-Sachs disease rAAVrh8-HexA / B was developed based on the preclinical data presented above and the It was administered due to the lack of treatment available for patients with Sachs' disease.

[0230] Three weeks before treatment, subjects (approximately 30 months of age) with advanced infantile Tay-Sachs disease were given several Several clinical safety studies have been conducted, and immunosuppressive regimens have been administered for approximately 7 days prior to treatment. The subjects were two mutant HexA alleles: 1) HexA: the most common HexA allele; A 4-base pair insertion (coding DNA: 1274-1278), which is a neugenase mutation; and 2) HexA: coding DNA: 82C → T (protein: Gln28). In addition, the subject may already have the following disease progression: 8 months: Excessive startle reflex Age 12 months: Macrocephaly with abnormal myelination on MRI, biomechanical changes on MRS Car abnormality Age 14 months: First afebrile seizure → diagnosis 17 months old: G-tube insertion Age 20 months: Emergency visit due to recurrent seizures The following symptoms were observed.

[0231] Subjects' seizures were treated with medication at baseline and rectal midazolam as needed. The subjects were placed under moderate control and administered a ketogenic diet, miglustat, via a G-tube. , Keppra, Prevacid, and clonazepam.

[0232] A composition containing a biological drug based on rAAVrh8-HexA / B rAAV is administered to a subject. The administered rAAVrh8-H was infused into the spleen at a rate dictated by the subject's CSF pressure. The target dose of the exA / B formulation was 1.0 × 10 per kg of brain weight. 14 Vector genome ( vg), or 1.0 × 10 14 It was vg.

[0233] The total dose administered to patients was 1040±130 g in 19-30 month old girls. The total dose was calculated based on brain weight. Approximately 75% was delivered to the cisterna magna and approximately 25% was delivered to the fluorescent It was administered into the spinal canal via a fluoroscopically guided lumbar intrathecal catheter (Fig. 74A). Following passive flow removal of 100 ml of CSF, 9 ml of AAVrh8 vector was infused into approximately 1 ml of the spleen. 3 ml of AAVrh8 vector was administered at the L2 For subjects with advanced disease, co-delivery of rAAVr No intrathalamic injections of h8-HexA / B were administered to subjects.

[0234] The biological drug used in the study was a separately produced AAVrh8-CB-c i-HEXA and AAVrh8-CB-ci-HEXB (rAAVrh8-HexA / The vectors were two non-replicating single-stranded adeno-associated virus vectors, designated as vector B). The molecular characteristics are listed in Tables 9 and 10. The AAVrh8 vector is a chicken beta- It encodes human HEXA and human HEXB under the control of the cytoplasmic promoter. The AAV vector plasmids used are depicted in Figures 65-67. It was formulated in Ca2+-free phosphate buffered saline.

[0235] rAAVrh8-HexA / B was generally well tolerated, with clinical outcomes at 3 months. There were no treatment-related, serious adverse events reported in the study update. No clinically relevant laboratory abnormalities were observed 3 months after treatment. No significant immune responses were observed. The clinical status of the subjects remained unchanged from baseline to 3 months. Neurological examination showed no signs of deterioration and the condition was stable. Brain magnetic resonance imaging (MRI) also showed no significant changes at baseline. No evidence of progression from baseline when compared with pre-treatment MRI of the brain These data are shown in Figure 69.

[0236] Data collected at 3 months also showed that a single dose of rituximab significantly reduced the CD1 9 and CD20 counts were completely suppressed (<1% of peripheral T cells), and IgG These data also indicated that IVIg infusion maintained the blood pressure within a safe range. The data is shown in Figure 70.

[0237] Subjects were randomly assigned to receive the AAVrh8 capsid at 3 months and had near-baseline neutralizing antibody levels against the AAVrh8 capsid. After 3 months, no neutralizing antibodies against the transgene product were observed. In addition, after 3 months, T cell responses to the transgene product and cytotoxicity to the capsid were also observed. No adverse T cell responses were observed. regulatory Stimulating a response is a key factor in future immune responses. This confirms the successful induction of long-term immune tolerance to the capsid, preventing response.

[0238] Very slight increases in the enzymes AST (less than 2x baseline) and ALT A slight increase (less than twice the upper limit of normal) was observed over the first 21 days, but spontaneous There was also evidence of systemic inflammation based on high-sensitivity C-reactive protein or total complement activity. Liver ultrasound and pediatric gastroenterology examinations also revealed no specific pathology.

[0239] β-Hexosaminidase A activity was determined using the 4MUGS assay. In this study, the CSF β-hexosaminidase A activity of the subject was 0.46% of normal. After 3 months, the β-hexosaminidase A activity in the subject's CSF was 1 / 2 of the normal enzyme activity. This significantly increased to 1.44%, representing a more than three-fold increase from baseline. Serum and CS levels before and up to 3 months after AAVrh8-HexA / B administration The enzymatic activity of HexA in F is shown in FIG.

[0240] As shown in Figure 71, GM2 ganglioside in cerebrospinal fluid (CSF) was This was due to a reduction of approximately 25% in the enzyme activity of β-hexosaminidase A in CSF. A three-fold increase from baseline in Tay-Sachs disease patients was observed, suggesting that the disease This indicates that a decrease in GM2 ganglioside, which is thought to be the cause of the progression of In addition, β-hexosaminidase A protein, as measured by Western blot, Expression of α-amyloid was also increased from baseline to 3 months. These data are shown in Figure 72. vinegar.

[0242] [Table 10]

[0243] [Example 15] A second subject (approximately 3 months of age) with progressive infantile Tay-Sachs disease received rAAVrh8- HexA / B was administered. Three weeks prior to treatment, subjects underwent several clinical safety tests. The subjects were administered an immunosuppressive regimen for approximately seven days prior to treatment. HexA alleles: 1) HexA: 1.75 kb deletion in exons 11-13 and 2) HexA protein: Val381 in exon 10. * truncation mutations Has.

[0244] Prior to administration of rAAVrh8-HexA / B, subjects had normal laboratory values ​​and showed growth and He was clinically well, with normal development and no evidence of seizures or hyperactive startle responses. The control had approximately 1% of the hexosaminidase activity compared to wild-type activity.

[0245] [Example 16] A clinical study of rAAVrh8-HEXA / B was designed. HEXA and erythropoietin in Tay-Sachs disease (TSD) or Sandhoff disease (SD) Bilateral intrathalamic administration of AAVrh8 vectors encoding HEXB individually Designed as a two-stage, dose-escalation, and safety / efficacy study for intrathecal and intrathecal administration. Clinical studies are summarized below. GM2 Gangliosidosis Due to the rapidly progressive and fatal nature of , and the lack of approved therapies, research has No placebo or active control groups will be utilized. Treatment will not be blinded.

[0246] The subjects in this study were under 18 months of age (premature infants (gestational age < 18 months)) at the time of gene transfer. 37 weeks) based on gene mutation analysis and symptom onset Infants of either sex with infantile-onset TSD or SD. The HEXA gene encodes the α subunit, or the H gene encodes the β subunit. Subjects must have the respective mutation in the EXB gene. The patient was considered a suitable surgical candidate (according to the study neurosurgeon) based on his ability to sit for 5 seconds. (confirmed based on physical examination and MRI findings), serum HexA activity less than 5% of normal and do not carry the G269S or W574C mutation. Based on the test assay threshold, patients were also seronegative for AAVrh8 neutralizing antibodies. Other inclusion / exclusion criteria may also be applied.

[0247] The study was an open-label, non-randomized, viral vector-based study using rAAVrh8-H A single dose of EXA / B administered bilaterally intrathalamic (BiTh) and intrathecally (IT) Subjects will be enrolled in the study in two stages (Figure 73) as follows: Phase 1: Four subjects were randomly assigned to a sequential, dose-escalating study to determine the optimal dose. Dose selection will be based on safety, biomarker, and further data. Phase 2: To determine safety / efficacy, up to Approximately 10 subjects will be treated with the optimal dose identified in the first phase.

[0248] All subjects will be followed for up to four years to determine the ongoing safety and efficacy of treatment. It is planned to participate in a long-term follow-up (LTFU).

[0249] Study procedures were administered over the course of 2 days to minimize the risk of prolonged anesthesia. At Visit 1a / Day 0, subjects will receive rAAVrh8-HEXA / B, At Visit 1b / Day 1, subjects received bilateral intraparenchymal injections of rAAVr All injections were performed with rAAVrh8-HEXA and rAAVrh8-HEXA / B. It is composed of a 1:1 mixture with rh8AAV-HEXB.

[0250] To prevent the risk of an inflammatory response, AAV-transduced cells were immunocompetent against the AAVrh8 capsid. To protect against an immune response, subjects were immunosuppressed prior to administration of AAVrh8-HexA / B treatment. The immunosuppressive regimen is maintained long-term as planned. Beginning on day -16 of the study, begin the following: ·Body surface area 1m 2 375 mg of rituximab per 10 mg / kg Solu-Medrol ·Body surface area 1m 2 1 mg of sirolimus per 2 mg / kg of prednisolone per day 1 to 1.5 mg / kg of lansoprazole per day Trimethoprim, 10 mg / kg per dose, given three times weekly (Monday, Wednesday, Friday) / sulfamethoxazole Day -7: Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Rituximab infusion required to sustain a CD20 count above 5% Day -2: Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Day 0 / BiTh injection day Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Day 1: IT injection day Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Days 2-7: Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Intravenous immunoglobulin (IVIG) administration: immunoglobulin levels are 700 ml / The dose should be below 700-1000 mg / dL. Adjust the volume to maintain the desired level after vector injection. Day 14: Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Day 21: Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Week 4 / Month 1: Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Administration of IVIG Week 4 / Month 2: Continuation of sirolimus, prednisolone, and lansoprazole Continuation of trimethoprim / sulfamethoxazole Administration of IVIG Week 12 / Month 3: Continuation of sirolimus Continuation of trimethoprim / sulfamethoxazole Administration of IVIG 24th week / 6th month - Withdrawal of sirolimus under the guidance of the hospital's consulting pharmacist

[0251] Intrathalamic (ITh) administration For the first phase, the clinical dose and injection are proposed to be delivered to the thalamus (Th). For example, the input capacity is 2.8 x 10 as shown in Table 11. 12 ~1.1×10 13 vg / ml.

[0252] [Table 11]

[0253] The amount of thalamus filled with vector, or the volume of distribution (Vd), is determined by the volume of the target brain region (thalamus). The product is the distance the vector will diffuse from the point source of delivery. It can be calculated based on the injected volume (Vi) multiplied by a correction factor. aVd:Vi ratio from injection studies (Yin, Richardson et al. 2010) (Yin et al, 2010) was assumed to be 3.0. The volume to the human thalamus is 1.08, as shown in Table 12. mL Vi, and 4.35 ml 3 Calculated as Vd (77% of total thalamic volume per side) I calculated.

[0254] [Table 12]

[0255] A Th injection volume of 1.08 ml was offered for subjects 1 to 3 in Phase 1 of the clinical trial. Low-, medium-, and high-dose thalamus injections are at or exceed the doses infused. The proposed adjusted clinical dose for intravenous administration is 7.2 x 10 12 ~1.4×10 13 vg is.

[0256] Intrathecal (IT) administration The proposed human dose for intrathecal administration is 2.03 x 10 13 ~8.13×1013 vg dose range, with a maximum injection volume of 8 mL (see table below) The latter value represents an IT dose of 8.0 × 10 across all treated subjects. 13 vg and set It is proposed for use in clinical studies.

[0257] [Table 13]

[0258] Throughout the procedure, the subject is placed under general anesthesia with intubation. While performing the infusion at 0.1 μL / min, remove the right infusion cannula, preventing blockage. and vector primed and attached to a delivery syringe and pump. The catheter is placed stereotaxically into the target area in the right thalamus. The left arm is fixed on the scalp with anchoring ligatures and adhesive dressings. Repeat the same steps for placement of the second catheter on the side. Monitor the intralid pressure.

[0259] The infusion rate begins at 0.5 μL / min and increases every 5 min (1.0 μL / min → 2. The study drug was administered via a microinfusion pump and the study drug was administered via a HexA Each vector was injected via a syringe containing a 1:1 mixture of the vector and the HexB vector. Inject into the catheter.

[0260] IT administration: IT drug infusion is administered at a rate dictated by CSF pressure. A total of 6.0 ml is administered through a high-neck catheter. 1.0 ml was delivered to the vertebral level / cisterna magna, and 2.0 ml was delivered to the thoracolumbar level. Under this guidance, the Tuohy needle is inserted into the subarachnoid space. Insertion into the catheter is verified by spontaneous CSF flow. A total of 6-7 mL of CSF is delivered by gravity. The tissue was then extracted with a flexible Excelsior ( SL-10 (registered trademark) Microcatheter (Stryker Neurova scular, Stryker) near or into the cisterna magna. A syringe containing a 1:1 mixture of HexA and HexB is attached to the catheter. Following administration of 6.0 ml at the high cervical / cisternal level, the microcatheter was inserted into the inferior The patient is then transferred to the thoracic-lumbar level and a second bolus of 2.0 ml is administered. Then, the microcatheter (dead volume: approximately 0.3 mL) was flushed with 0.5 mL of physiological saline. The surgeon's discretion, based on spinal anatomy and other considerations, The dose was administered by two separate IT injections at the high cervical / cisternal and thoracolumbar levels. It can be given.
