Abstract
Description
[0001] Field of technology to which the invention relates
[0002] The present invention relates to a conjugate comprising a peptide carrier and a therapeutic molecule, wherein the peptide carrier is characterized by specific domains, and the therapeutic molecule is a nucleic acid formed from trinucleotide repeats. The present invention also relates to the use of said conjugate in methods of treatment or as a drug, especially in the treatment of disorders caused by trinucleotide repeats, such as myotonic dystrophy (DM1).
[0003] Prerequisites for the creation of the invention
[0004] Nucleic acid-based therapeutics are genomic drugs with the potential to transform healthcare. Research has demonstrated that these therapeutics have potential for use in a wide range of diseases. In particular, the use of antisense oligonucleotide-based approaches to modulate mRNA expression has emerged as a valuable therapeutic tool in the cutting-edge field of personalized medicine.
[0005] However, the therapeutic development of these promising antisense therapeutics has been hampered by insufficient cell permeability and unsatisfactory distribution characteristics.
[0006] There is therefore a clear and pressing need to improve the delivery of antisense oligonucleotides to provide more effective therapy for genetic diseases such as devastating trinucleotide repeat disorders.
[0007] Trinucleotide repeat disorders are genetic diseases characterized by the presence of an abnormally large number of repeats of a specific three-nucleotide sequence in genomic DNA, also known as trinucleotide repeat expansions. Trinucleotide repeat expansions are a specific type of microsatellite repeat, often referred to as microsatellite expansions. Typically, there is a threshold number of repeats present in a healthy individual, and if the number of repeats exceeds this threshold, the disease becomes pathogenic. This threshold number varies depending on the disease and the affected genes. In these diseases, the number of repeats can also serve as an indicator of disease severity. Generally, a higher number of repeats indicates a more severe case of the disease.The number of repetitions can also be used to predict the age at which diseases may begin, with a higher number of repetitions indicating an earlier onset.
[0008] Currently, 14 trinucleotide repeat disorders affecting humans are known. These disorders can be grouped using several methods, such as by determining the location of the trinucleotide repeat within the gene, such as its location in a protein-coding ORF; in an exon; or in the untranslated region. Alternatively, they can be grouped by the sequence of the triplet repeat. In many trinucleotide repeat disorders, the triplet repeat is "CAG," encoding glutamine; this group of disorders is typically referred to as polyglutamine disorders. However, trinucleotide repeats with different sequences are known and can be classified as non-polyglutamine repeat disorders.
[0009] One of the trinucleotide-related disorders related to non-polyglutamine repeat disorder is myotonic dystrophy type 1 (DM1). DM1 is caused by the trinucleotide repeat "CTO" present in the 3' UTR of the DMPK (myotrophic dystrophy protein kinase) gene. The typical repeat number for this gene ranges from 5 to 34 repeats. Repeat numbers greater than 34 may cause some symptoms of the disease, while repeat numbers greater than 50 indicate pathogenicity.
[0010] DM1 and other trinucleotide repeat disorders typically affect the neuromuscular system and there is currently no effective treatment.
[0011] While the use of antisense oligonucleotides that can bind to repeat regions and disrupt splicing or translation is theoretically promising, and has been demonstrated in vitro, their use as therapeutic agents has proven impossible due to the difficulty of delivering these molecules to affected cells. This applies to the treatment of a wide range of genetic diseases, including disorders caused by trinucleotide repeats.
[0012] Viruses have been proposed as delivery vehicles, but their use is limited by the immunotoxicity of the viral envelope protein and potential oncogenic effects. A number of non-viral delivery vectors have been developed as an alternative, with peptides proving the most promising due to their small size, specific targeting, and ability to transcapillary deliver large biological cargo molecules (biocargo). Several peptides have been shown to be able to penetrate cells either independently or with biocargo.
[0013] In recent years, cell-penetrating peptides (CPPs) have been conjugated to antisense oligonucleotides (specifically, neutrally charged phosphorodiamidate morpholine oligomers (PMOs) and peptide nucleic acids (PNAs)) to enhance the cellular delivery of these oligonucleotide analogs by efficiently transporting them across cell membranes to reach their pre-mRNA target sites in the cell nucleus. It has been found that therapeutics that include PMOs conjugated to specific arginine-rich peptides (referred to as P-PMOs or peptide-PMOs) can effectively penetrate target cells.
[0014] Specifically, peptides derived from the internalization of PNA / PMO (Pip) were developed. These peptides are arginine-rich CPPs consisting of two arginine-rich sequences separated by a short central hydrophobic sequence. These "Pip" peptides were engineered to enhance serum stability while maintaining high levels of exon skipping, initially by conjugation to the PNA cargo molecule. Additional derivatives of these peptides were created as PMO conjugates, which, as shown in DMD (Duchenne muscular dystrophy) models, after systemic administration to mice, provide therapy to skeletal muscle throughout the body, and, importantly, also to the cardiac muscle.
[0015] Although these carrier peptides are effective, their therapeutic use is hampered by their associated toxicity.
[0016] Alternative carrier peptides with a single arginine-rich domain, such as R6Gly, were also obtained. These peptides were used to produce peptide conjugates with antisense oligonucleotides, which exhibited reduced toxicity; however, these conjugates were less effective than Pip peptides.
[0017] Furthermore, virtually all development of carrier peptides has been conducted in the context of DMD treatment. Peptides with a hydrophobic central domain have been shown to be particularly active in the treatment of DMD. To date, the use of such carrier peptides in other neuromuscular diseases with different etiologies and pathologies has not been studied.
[0018] Thus, there are currently no available carrier peptides that can be used in conjugates with therapeutic nucleic acids for the treatment of genetic disorders, particularly those that are not related to diseases that arise as a result of other pathology, such as trinucleotide repeat disorders.
[0019] A challenge in the field of carrier peptide technology has been to address the issue of efficacy-toxicity balance. The present inventors have now identified, synthesized, and tested conjugates containing improved carrier peptides with defined structures covalently linked to a therapeutic nucleic acid for the treatment of a trinucleotide-mediated disorder, which addresses at least this issue.

[0041] Detailed description of the invention
[0042] The present invention is based on the discovery that the attachment of specific peptide carriers to a nucleic acid, which can be used for the prevention and treatment of trinucleotide repeat disorders, allows the nucleic acid to effectively penetrate target cells and bind to trinucleotide repeats present in the genes of affected individuals, exerting a targeted effect on their expansion. This activity reduces the levels of transcript and / or protein repeat expansion present in the cell, thereby blocking their pathological effects on the cellular splicing mechanism, normalizing splicing and improving the physiological state of these individuals.
[0043] An advantage is that the peptide carriers described herein likely enhance the resistance of the therapeutic nucleic acid to cleavage, increase its ability to penetrate target cells, and provide targeted action on trinucleotide expansion, thereby implementing treatment. Furthermore, the conjugates proposed in the invention exhibit significantly lower toxicity compared to conjugates formed using known peptide carriers. Thus, the conjugate provides a means of effectively delivering nucleic acid for the treatment of trinucleotide repeat disorders while remaining nontoxic to the individual.
[0044] This invention was the first to demonstrate that any peptide carriers with a hydrophobic core are effective for the treatment of neuromuscular diseases other than DMD. Previous studies focused on the use of peptide carriers for the delivery of therapeutic agents for the treatment of DMD. The pathology of DMD differs significantly from that of trinucleotide repeat-associated disorders. Specifically, DMD involves active muscle degeneration and muscle renewal and repair, including inflammation, while trinucleotide repeat-associated disorders such as myotonic dystrophy type 1 (DM1) involve muscle dysfunction without overt degeneration.In the present invention, it was discovered that peptide carriers interact with muscle membranes, ensuring efficient delivery of the therapeutic molecule, and the membrane types they interact with vary greatly between degenerated and non-degenerated muscle, i.e., between DMD and trinucleotide repeat-mediated disorders. Unlike degenerative diseases such as DMD, in DM1 the muscle membrane is not disrupted, and therefore, it might be expected that conjugate penetration into muscle tissue should be inhibited, which is much more difficult to achieve. However, the data obtained in the present invention indicate for the first time that peptide carriers are not only effective in delivering to degenerated muscle for the treatment of DM1, but, as unexpectedly found, are more effective against DM1 than DMD.
[0045] According to the data presented in the present invention, the conjugates of the invention maintain high levels of efficacy and delivery to critical target tissues affected by trinucleotide-mediated disorders, such as the gastrocnemius and quadriceps skeletal muscles. Furthermore, these conjugates demonstrated increased efficacy compared to previously available peptide carriers when used in the same conjugate. The conjugates of the invention target mutant CUGexpanded-DMPK transcripts (DMPK transcripts with a CUG expansion), preventing the formation of nuclear foci and thereby preventing detrimental sequestration of the MBNL1 splicing factor by nuclear RNA foci and, as a result, reducing the loss of function of the MBNL1 factor, which is responsible for splicing defects in multiple genes, and muscle dysfunction.
[0046] This is demonstrated herein by the reduction in the number of nuclear foci formed by DMPK transcripts containing repeat expansions following administration of the conjugate of the invention and by the correction of gene splicing following administration of the conjugate of the invention, i.e., those genes whose splicing is typically impaired in DM1 due to the reduced availability of MBNL1 sequestered by transcripts with an increased number of trinucleotide repeats. In particular, the conjugates presented herein demonstrated the ability to correct splicing by 50-90% relative to healthy controls, with the exception of exon 7a of clicn1 and exon 5 of mblnl1, and including exon 22 of serca, compared to untreated cells / individuals.This has also been demonstrated by the improvement in the physiological state of trinucleotide-induced disorders, as shown in the present description in DM1 models, where normalization and correction of myotonin in mice was observed up to complete recovery even after a single injection of the conjugates indicated in the present description.
[0047] In the creation of the invention, it was unexpectedly found that the peptide carriers used in the conjugate effectively delivered the therapeutic molecule into the nuclear compartment and into nuclear aggregates of DMPK transcripts at a concentration sufficient to ensure a favorable stoichiometric interaction with the CUG mutation.
[0048] At the same time, the conjugates of the invention were effective in vivo, as evidenced by a reduction in clinical signs after systemic injection and reduced toxicity detected after measuring biochemical markers. Of extreme importance is the fact that the conjugates of the present invention unexpectedly demonstrated reduced toxicity after a similar systemic injection in mice compared to previously described carrier peptides in the same conjugate. As demonstrated herein, the conjugates of the invention did not lead to a significant increase in toxicity markers compared to saline at therapeutically relevant doses, while cell viability was maintained, while conjugates using prior art peptide carriers resulted in significant cell death.Following administration of the conjugates to mice, a short recovery period was observed, which was much faster than following administration of conjugates formed using previously available peptides.
[0049] Thus, the conjugates proposed in the invention can be more successfully used for the safe and effective therapy of trinucleotide repeat disorders in humans, they open the way for the treatment of these devastating diseases that would otherwise be incurable.

Biodistribution assessment of DPEP1.9 and DPEP3.8 conjugates demonstrated optimal delivery to tissues most susceptible to damage in DM1. PMO was detected by a custom-made ELISA assay using digoxigenin- and biotin-labeled probes. At 2 weeks post-treatment, PMO concentrations in muscle tissue were still >1 nM compared to the low picomolar concentrations found after injections of naked PMO (despite a >20-fold difference in molarity between naked PMO and DPEP-PMO conjugate treatments) (n=4).

[0464] Figure 17 shows the pharmacokinetic properties of various DPEP1 / 3-[CAG]7PMO conjugates as measured in serum following a single 5 mg / kg dose. Custom-made ELISAs were used to quantify serum concentrations, which reached 500-800 nM 5 min after IV injection of the compounds at a dose of 5 mg / kg, decreasing to 100 nM after 1 h and 10 nM after 3 h. At 6 h after administration, concentrations were ~1 nM, by which time most of the compounds had already been eliminated from the body or delivered to the tissues of interest;

[0480] Synthesis and screening of peptides for R-RMO
[0481] a) Obtaining a library of peptide variants
[0482] Peptides were either prepared at 10 μmolar scale using an Intavis Parallel Peptide Synthesizer or at 100 μmolar scale using a CEM Liberty Blue™ peptide synthesizer (Buckingham, UK) with preloaded Fmoc-β-Ala-OH Wang resin (0.19 or 0.46 mmol / g, Merck Millipore) using standard Fmoc chemistry and following the manufacturer's recommendations. For syntheses using the Intavis Parallel Peptide Synthesizer, duplicate coupling steps were used with PyBOP / NMM coupling mix, followed by capping with acetic anhydride after each step. For synthesis using the CEM Liberty Bluer peptide synthesizer, single standard couplings were performed for all amino acids except arginine, for which double couplings were performed.The coupling was performed once at 75°C for 5 min at 60 W microwave power, except for arginine residues, which were coupled twice. Each deprotection reaction was performed twice at 75°C, once for 30 s and then for 3 min at 60 W microwave power. After completion of the synthesis, the resin was washed with DMF (3 × 50 mL), and the N-terminus of the solid-phase-bound peptide was acetylated with acetic anhydride in the presence of DIPEA at room temperature. After N-terminus acetylation, the resin-bound peptide was washed with DMF (3 × 20 mL) and DCM (3 × 20 mL). Peptides were cleaved from the solid support by treatment with a cleavage mixture consisting of trifluoroacetic acid (TFA): H2O: triisopropylsilane (TIPS) (95%: 2.5%: 2.5%: 3-10 mL) for 3 h at room temperature. After the release of the peptides, excess TFA was removed by sparging with nitrogen.The crude peptide was precipitated by adding cold diethyl ether (15–40 mL depending on the scale of the synthesis) and centrifuged at 3200 rpm for 5 min. The crude peptide beads were washed three times with cold diethyl ether (3 × 15 mL) and purified by RP-HPLC using a Varian 940-LC HPLC system equipped with a 445-LC scale-up module and a 440-LC fraction collector. Peptides were purified by semi-preparative HPLC on an RP-C18 column (10 × 250 mm, Phenomenex Jupiter) using a linear gradient of CH3CN in 0.1% TFA / H2O at a flow rate of 15 mL / min. Detection was performed at 220 nm and 260 nm. Fractions containing the desired peptide were pooled and lyophilized to yield the peptide as a white solid (see yields in Table 2).
[0483]
[0484] b) Synthesis of a library of peptide-RMO conjugates
[0485] The 21-mer antisense sequence of PMO was used as the triplet repeat sequence (CAGCAGCAGCAGCAGCAGCAG (SEQ ID NO: 95)), which was also referred to as [CAG]7. The PMO sequence targeting the CUG / CTG repeats with an increased copy number (5'-CAGCAGCAGCAGCAGCAGCAG-3' (SEQ ID NO: 95)) was purchased from Gene Tools LLC. It was also referred to as [CAG]7PMO herein. The peptide was conjugated to the 3' end of PMO via the C-terminal carboxyl group. For this purpose, 2.5 and 2 equivalents of PyBOP and HOAt in NMP, respectively, were used in the presence of 2.5 equivalents of DIPEA and a 2.5-fold excess of the peptide relative to PMO dissolved in DMSO. In In general, PyBOP (19.2 μL, 0.3 M in NMP), HOAt (16.7 μL, 0.3 M in NMP), DIPEA (1.0 mL), and PMO (180 μL, 10 mM in DMSO) were added to a solution of the peptide (2500 nmol) in N-methylpyrrolidone (NMP, 80 μL). The mixture was allowed to stand for 2.5 h at 40°C, and the reaction was stopped by adding 0.1% TFA in H2O (300 μL).The above solution was purified by ion exchange chromatography using a Gilson HPLC conversion system. PMO-peptide conjugates were purified on an ion exchange column (Resource S 4 mL, GE Healthcare) using a linear gradient of sodium phosphate buffer (25 mM, pH 7.0) containing 20% CH3CN. Sodium chloride solution (1 M) was used to elute the conjugate from the column at a flow rate of either 4 mL / min or 6 mL / min. Fractions containing the desired compound were immediately desalted. Removal of excess salts from the peptide-PMO conjugate was accomplished by filtration of the fractions collected after ion exchange chromatography using an Amicon® ultra-15 3K centrifugal filter device. The conjugate was lyophilized and analyzed by MALDI-TOF. The conjugates were dissolved in sterile water and filtered through a 0.22-μm cellulose acetate membrane before use. The peptide-PMO conjugate concentration was determined by the molar absorbance of the conjugates at 265 nm in 0.1 N HCl.HCl solution (for yield data see Table 2).

[0487] Animal model and injection of antisense oligonucleotides (ASOs).
[0488] The experiments were carried out at the University of Oxford or at the Centre fonctionnelles» (Faculty of Medicine, Sorbonne University) in accordance with the laws of the United Kingdom and France (approval of the Ethics Committee No. 1760-2015091512001083v6). Intravenous injections of HSA-LR or C57BL / 6 mice were performed using single or multiple administrations via the tail vein. Doses of 5, 7.5, 12.5, 30, or 40 mg / kg peptide-PMO-CAC7 conjugate and 12.5 or 200 mg / kg PMO were obtained by dilution in 0.9% saline and administered at a volume of 5-6 μl / g body weight. Multiple injections were performed at intervals of 2 weeks. Myotonia was assessed and tissues were collected 2 weeks after the final injection. For long-term experiments, tissues were collected 3 months after injection. For toxicology studies, tissues were collected 1 week later. Urine was analyzed using ELISA (R&D, catalog #MKM100), using samples diluted to match the standard curve.Data were standardized to urinary creatinine levels (Harwell) to determine urinary protein concentration.
[0489] In situ myotonia / muscle relaxation study. Isometric contractility of the gastrocnemius muscles was studied in situ. Mice were anesthetized with a ketamine / xylazine solution (80 mg / kg and 15 mg / kg, respectively). The knees and feet were fixed with clamps and pins. The distal gastrocnemius tendon was attached to the lever arm of a servomotor system (305 V, Dual-Mode Lever). Data were acquired and analyzed using a PowerLab system (4SP, ADInstruments) and software (Chart 4, ADInstruments). The sciatic nerve (crushed near its origin) was stimulated with a bipolar silver electrode using a supramaximal (10 V) rectangular pulse of 0.1 ms duration. Absolute maximal isometric tetanic force (P0) was measured during isometric contractions in response to electrical stimulation (frequency from 25 to 150 Hz, stimulation duration 500 ms).Myotonia was measured as the delay in muscle relaxation after P0 measurement.
[0490] Cell culture and treatment with peptide-PMO conjugate. Immortalized myoblasts from a healthy individual or a patient with DM1, which has 2600 CTG repeats, were cultured in a nutrient medium consisting of a mixture of M199:DMEM (ratio 1:4; Life technologies) supplemented with 20% FBS (Life technologies), 50 μg / ml gentamicin (Life technologies), 25 μg / ml fetuin, 0.5 ng / ml bFGF, 5 ng / ml EGF, and 0.2 μg / ml dexamethasone (Sigma-Aldrich). Myogenic differentiation was induced by transferring confluent cell cultures into DMEM myoblast medium supplemented with 5 μg / ml insulin (Sigma-Aldrich). Prior to treatment, WT or DM1 cells were differentiated for 4 days. The medium was then replaced with fresh differentiation medium containing peptide-PMO conjugates at concentrations of 1, 2.5, 10, 20, or 40 μM. Cells were harvested and analyzed 48 hours after treatment.Cell viability was assessed 2 days after transfection of human hepatocytes with 40 μM peptide-PMO conjugates or human myoblasts with 1, 2.5, 10, 20, or 40 μM using a fluorescence-based assay (Promega).
[0491] RNA extraction, RT-PCR and qPCR analysis. For mouse tissues, prior to RNA extraction, muscle was disrupted in TriReagent (Sigma-Aldrich) using the Fastprep system and Lysing Matrix D tubes (MP biomedicals). For human cells, prior to RNA extraction, cells were lysed in proteinase K buffer (500 mM NaCl, 10 mM Tris-HCl, pH 7.2, 1.5 mM MgCl2, 10 mM EDTA, 2% SDS, and 0.5 mg / ml proteinase K) for 45 min at 55°C. Total RNA was isolated using TriReagent according to the manufacturer's protocol. Reverse transcription of 1 μg of RNA was performed using the first-strand synthesis system (Life Technologies) according to the manufacturer's instructions in a total volume of 20 μl. Then, 1 μl of the cDNA preparation was used for semiquantitative PCR analysis according to the standard protocol (ReddyMix, Thermo Scientific). Primers are presented below in Table 3:
[0492]
[0493]
[0494] PCR amplification was performed for 25-35 cycles within the linear amplification range of each gene. PCR products were separated on 1.5-2% agarose gels, stained with ethidium bromide, and quantified using ImageJ software. Exon inclusion levels were determined as the percentage of inclusion relative to the total isoform signal intensity. To quantify mRNA expression, real-time PCR was performed according to the manufacturer's instructions. PCR cycles included a 15-min denaturation step followed by 50 cycles of denaturation at 94°C for 15 s, annealing at 58°C for 20 s, and extension at 72°C for 20 s.
[0495] Fluorescence in situ hybridization / immunofluorescence.
[0496] Fluorescence in situ hybridization (FISH) experiments were performed as described previously (6) using the Cy3-labeled 2'OMe(CAG)7 probe (Eurogentec). For combined FISH-immunofluorescence experiments, immunofluorescence staining was performed after the last FISH wash using a rabbit polyclonal antibody to MBNL1, followed by a secondary Alexa Fluor 488-conjugated goat anti-rabbit antibody (1:500, Life technologies).
[0497] ELISA-based measurements of oligonucleotide concentrations in tissues. A specialized hybridization-based ELISA was developed to determine the concentration of PMO oligonucleotides using phosphorothioate probes with phosphorothioate linkages (sequence (5'->3')
[0498] [DIG]C*T*G*C*T*G*C*TGCTGCT*G*C*T*G*C*T*G[BIO] (SEQ ID NO: 96)), dual-labeled with digoxigenin and biotin. The assay had a linear detection range of 5-250 pM (R2>0.99) in mouse serum and tissue lysates. The probe was used to determine the concentrations of peptide-PMO conjugates or naked PMO in eight different tissues (brain, kidney, liver, lung, heart, diaphragm, gastrocnemius, and quadriceps) from HSA-LR mice.
[0499] Results
[0500] The present invention utilized an arginine-rich cell-penetrating peptide having a specific structure, and demonstrated that the peptide conjugated with [CAG]7-morpholinophosphorodiamidate oligomer (PMO) significantly enhanced the delivery of ASO to striated muscles in the DM1 HSA-LR mouse model after systemic administration, compared with unconjugated PMO and other peptide carriers used in the conjugate strategy. Thus, low-dose treatment with the [CAG]7PMO peptide conjugate proposed in the present invention, which targets pathological expansions, was sufficient to both reverse splicing defects and myotonia in DM1 mice (HSA-LR) and normalize the entire disease-causing transcriptome.Furthermore, using muscle cells (myoblasts) isolated from a treated patient with DM1, it was demonstrated that the peptide-[CAO]7PMO conjugates of the present invention specifically target mutant CUGexp-DMPK transcripts, eliminating the detrimental sequestration of the splicing factor MBNL1 by nuclear RNA foci and, as a result, the functional loss of MBNL1 responsible for splicing defects and muscle dysfunction. The results obtained in creating the invention demonstrate that the peptide-[CAO]7PMO conjugates of the present invention induce highly effective and long-lasting correction of DM1-associated phenotypes at both the molecular and functional levels and convincingly confirm the possibility of using these peptide conjugates for systemic corrective therapy of DM1.
[0501] In the creation of the invention, data were obtained for conjugates containing peptide carriers that do not contain artificial amino acids such as X residues, which have a wider therapeutic window and a safer toxicity profile compared to previously known cell-penetrating peptides and are therefore more promising candidates for study in patients with DM1. These new-generation peptides, designated "DPEP1 and DPEP3," demonstrated high efficacy in reducing the number of pathogenic foci (Fig. 1) and correcting splicing defects in vitro when conjugated to the CAG7-repeat-bearing antisense oligonucleotide PMO (Figs. 2, 3, 4, and 19).No decrease in the cellular viability of human hepatocytes was observed at any of the concentrations studied (1-40 μM), in contrast to similar comparative conjugates formed using known Pip carrier peptides, such as Pip6a-PMO and Pip9b2-PMO, which induced significant cell death (>50%) when applied at a concentration of 40 μM (Fig. 7). Many of the concentrations studied did not reduce the cellular viability of human myoblasts and provided better survival compared to similar comparative conjugates formed using known Pip carrier peptides, such as Pip6a-PMO and Pip9b2-PMO, which induced cell death when applied at lower doses (Figs. 5 and 6).
[0502] Thus, in creating the invention, it was also analyzed whether the said new peptides are active in terms of correcting myotonia and splicing changes when studied on HSA-LR mice. For this purpose, the leader peptide carriers of the DPEP 1 and 3 series, such as DPEP1.9 and DPEP3.8, were tested in comparison with the peptide carrier DPEP 5.70 known from the existing state of the art. It was demonstrated that splicing defects (Fig. 4) and myotonia (Figs. 8, 9 and 10) were corrected to a level corresponding to the wild type within 2 weeks after treatment at a dose of 30 mg / kg with conjugates formed using both DPEP3.8 and DPEP1.9.
[0503] The biodistribution of naked PMO compared to conjugates formed with the carrier peptides DPEP 1.9 and DPEP3.8 was studied using ELISA to quantify the delivery of the peptide-[CAO]7PMO conjugate. Detection of PMO in tissues most susceptible to damage in DM1, such as the heart and brain, is important for drug delivery studies. A single intravenous injection of the peptide-[CAO]7PMO conjugate at a dose of 30 mg / kg or three injections of 200 mg / kg naked PMO (a total of 600 mg / kg) were performed in HAS-LR mice. Two weeks after administration, PMO was detected in the gastrocnemius muscle, quadriceps muscle, diaphragm, heart, and brain. When unconjugated naked [CAG]7PMO was administered, low to undetectable levels were detected in all tissues studied, but when [CAG]7PMO was conjugated to the peptide carriers DPEP1.9 and DPEP3.8, higher levels were detected despite injection at lower doses (molarity >20-fold).Overall, peptide-[CAG]7PMO conjugates were detected in the quadriceps, gastrocnemius, and diaphragm at 1 nM–4 nM and in the heart at 1 nM 2 weeks after 30 mg / kg injections (Fig. 17).
[0504]
[0505]
[0506] In creating the invention, the pharmacokinetic properties of the peptide-[CAG]7PMO conjugates proposed in the invention were also studied by performing measurements in serum after the administration of low doses (5 mg / kg) of the peptide-[CAG]7PMO conjugates. It was found that serum concentrations, which reached 500-800 nM 5 min after IV administration, decreased to 100 nM after 1 hour and 10 nM after 3 hours. After 6 hours after treatment, the concentrations were ~1 nM, while the main part of the compound had already been eliminated from the body or delivered to the tissues of interest (Fig. 18).
[0507] Preliminary toxicology evaluation of conjugates formed with the DPEP3.8 and DPEP1.9 carrier peptides in wild-type mice demonstrated that ALP, ALT, AST, KIM-1, creatinine, BUN, and NGAL levels were similar to those observed after saline control injections, in contrast to the fold increases typically induced by currently known Pip series peptide carriers. Using these preliminary data, the invention demonstrated that [CAG]7PMO conjugates formed using DPEP peptides had similar in vivo activity to those obtained using Pip6a, but had a broader therapeutic window (Figs. 11, 12, and 21).
[0508] Furthermore, no significant trend (decrease) was found in the body weight of five HSA-LR mice injected with a single dose of 30 mg / kg of the DPEP3.8-[CAG]7-derived conjugate compared with five HSA-LR mice injected with saline (Fig. 16).
[0509] Furthermore, the recovery period of HSA-LR mice after injections of DPEP-based [CAG]7PMO conjugates was shorter than after injection of conjugates formed with known peptide carriers from the state of the art, such as Pip6a (Table 5).
[0510]
[0511] Upon closer evaluation of the efficacy of the conjugates proposed in the invention, it was also found that splicing defects and myotonia were corrected to levels corresponding to the wild type for at least 3 months (Figs. 19 and 20, respectively) after administration of the DPEP-[CAG]7PMO peptide conjugates. A 50% reduction in splicing errors and myotonia was also observed after administration of the conjugates at a dose of 7.5 mg / kg.
[0512] It is important to note that conjugates formed using prior art peptide carriers, such as Pip6a-[CAG]7PMO, could not be tested at doses >20 mg / kg due to high mouse mortality rates, in contrast to the conjugates of the invention, the concentrations of which can be increased more than 5-fold without any signs of mortality. Furthermore, toxicity screening conducted in the invention revealed changes in Kim1 levels relative to saline levels 2 days after treatment only at doses exceeding 30 mg / kg (Fig. 21).
[0513] Efficacy and toxicity data demonstrate that conjugates formed with the DPEP1 and DPEP3 series of carrier peptides proposed in the invention exhibited the most pronounced activity in blocking MBNL1 sequestration, which results from the expansion of CTG repeats in individuals suffering from DM1, and induced a low level of toxicity. These conjugates were able to completely correct the DM1 phenotype both at the molecular level by normalizing splicing and at the muscle level by correcting myotonia up to achieving levels corresponding to the wild-type. Furthermore, these new conjugates also had wider therapeutic windows compared to conjugates formed with previously known peptide carriers and, therefore, are more suitable for implementing their properties in a clinical setting.
[0514] In summary, the invention provides clear evidence that (1) the peptide-[CAG]7PMO conjugate blocks the pathological interactions of MBNL1 with the nuclear mutant CUGexp RNA and rescues the resulting effects on RNA splicing; (2) the antisense oligonucleotide-peptide conjugate approach enables delivery of therapy to inaccessible tissues such as the diaphragm heart; (3) the potent action of [CAG]7PMO in directly targeting the disease-causing mutation, combined with the highly efficient in vivo drug delivery properties of the peptide carrier technology, enables a marked reversion of the DM1 phenotype in mice (HSA-LR) to wild-type levels even months after treatment cessation.These pieces of evidence strongly support that peptide-[CAG]7 conjugates are likely to have potent disease-modifying effects against DM1.
[0515] In fact, experiments conducted during the development of this invention demonstrated that the effect observed in HSA-LR mice not only prevents the worsening of DM1 pathology, but also clearly reverses the disease phenotype. Expression of a large number of CUG transcripts occurs already in pups, and in HSA-LR mice, pronounced myotonia is present by 1 month of age. Animals used to obtain results confirming the concept of this application were treated at least 2 months and even 7 months of age, which is well beyond the age at which the molecular and functional DM1 phenotype develops.
[0516] 3. Conclusions
[0517] - Conjugates containing the carrier peptides DPEP and [CAG]7PMO (10 μM) can reduce the number of nuclear foci (at doses that do not result in decreased cell viability) in myoblasts from a patient with DM1 and in controls by >50%. None of the concentrations studied (1-40 μM) caused a decrease in cell viability, in contrast to comparator conjugates formed with other carrier peptides, which induced pronounced cell death (>50%) when used at concentrations of 20 μM or higher.
[0518] - Conjugates containing the carrier peptides DPEP and [CAG]7PMO exhibited positive pharmacokinetic properties, and biodistribution assessment confirmed optimal delivery to tissues most susceptible to damage in DM1.
[0519] - Conjugates containing DPEP and [CAG]7PMO carrier peptides induced 50%-90% splicing correction in HSA-LR mice for Clcn1 exon 7a, Serca exon 22, Mbnl1 exon 5, and Ldb3 exon 11 at a dose (30 mg / kg, IV) that was less toxic than the 12.5 mg / kg dose of the reference conjugates formed with other carrier peptides. RT-PCR analyses also demonstrated normalization of splicing to wild-type levels when DPEP 1.9 and DPEP3.8-containing conjugates were administered at doses of 30 and 40 mg / kg. Splicing correction was maintained for at least 3 months after treatment and was also significant after a single administration at low doses (5 and 7.5 mg / kg).
[0520] - Conjugates containing DPEP and [CAG]7PMO carrier peptides reduced myotonia to wild-type levels following a single (IV)b injection at a dose of 40 mg / kg or 30 mg / kg, as assessed by quantitative myotonia assessment and electromyographic measurements of myotonia. Moderate correction of myotonia was also observed after four injections at a dose of 7.5 mg / kg of conjugates containing DPEP3.8 or DPEP1.9.
[0521] - Conjugates containing the carrier peptides DPEP and [CAG]7PMO, when injected (IV) at a dose of 30 mg / kg, induced a shorter period of lethargy in wild-type mice compared to a single injection of the reference conjugates formed with other carrier peptides at a dose of 12.5 mg / kg (>1 h). Urine biochemistry to assess renal function and blood analysis showed no change compared to saline in wild-type mice and little change in the levels of Kim1 and urine protein in HSA-LR mice after administration at a dose of >30 mg / kg.
