[0041] The present disclosure is directed to modulation of OPN mRNA and protein expression. Human genetic modification and the alteration of gene expression have been developed to treat several disorders. In some embodiments, the delivery of exogenous deoxyribonucleic acids (DNAs) to cells has been tested for years to restore the expression of missing genes in genetic disorders. In some embodiments, gene editing has also emerged to insert, delete, or replace genes to make specific changes to DNA. In some embodiments, oligonucleotide-based therapy can be developed to halt the progression of numerous disorders by affecting ribonucleic acid (RNA) or protein expression. In some embodiments, oligonucleotides are easy to synthesize and do not require integration into the genome, making their delivery less challenging. In some embodiments, different oligonucleotide structures have been designed and classified as (i) aptamers, which modify peptide and protein structures or enhance drug delivery; (ii) double-stranded RNA interference (RNAi), which reduces gene expression; (iii) double-stranded small activating RNAs (saRNAs), which induce gene expression; and (iv) antisense oligonucleotides (ASOs). In some embodiments, ASOs are single-stranded synthetic deoxynucleotide or ribonucleotide analogues that attach to complementary RNA sequences by Watson-Crick base pairing. For example, ASOs can be between 15 and 30 nucleotides in length, that attach to complementary RNA sequences by Watson-Crick base pairing. These chemically modified oligonucleotides can target both protein-coding (messenger RNA or mRNA) and noncoding RNA molecules (microRNA) to modulate gene expression.
[0042] FIG. 1 shows SPP1 gene and translated splice variants in some embodiments. Referring to FIG 1, the translated splice variants may include, for example, OPN-a, OPN-b, OPN-c, OPN-4, or OPN-5, in some embodiments. The present disclosure relates to a methodof reducing expression levels and / or activity of SPP1 or OPN in a cell comprising administering an effective amount of the compound to the cell or an effective amount of the pharmaceutical composition to the cell. The present disclosure relates to a method of reducing expression levels and / or activity of SPP1 or OPN in a subject in need thereof comprising administering an effective amount of the compound to the subject or an effective amount of the pharmaceutical composition to the subject. In some embodiments, it is unexpectedly found that Hu-01 (SEQ. ID. NO. 1) and Hu-03 (SEQ ID. NO: 3) down-regulated, knocked down, or reduced SPP1 or OPN production. For example, in some embodiments, SEQ ID NO: 6-8, which are binding site for Hu-01, Hu-02, and Hu-03 respectively, sequences are listed in the Listing Table in the Appendix, full sequence information refer to NCBI Reference Sequence: NP_110418.1; Gene ID: 6696).
[0043] FIG. 2 and FIG. 3 illustrates a possible molecular mechanism for PMOs such as Hu-01 and Hu-03 in some embodiments. Referring to FIG. 2, and without being bound by theory, PMOs such as Hu-01 work through translational blocking. PMOs are short singlestranded DNA analogs that are built upon a backbone of morpholine rings connected by phosphorodiamidate linkages. PMOs bind to complementary sequences of target mRNA by Watson-Crick base pairing to block protein translation through steric blockade in a RNase H independent manner. They bind to mRNA and prevent the mRNA-entering ribosome so translation to protein is prevented.
[0044] Referring to FIG. 3, and without being bound by theory, PMOs such as Hu-03 work by binding to complementary sequences of pre-mRNA near exon-intron boundaries, specifically blocking splicing sites or splicing enhancers. Hu-03 binding to an exon / intron junction within a pre-mRNA thereby modulates the splicing process. This modulation induces mis-splicing of the nascent transcript, which ultimately causes a frameshift and introduces a premature termination codon (PTC) in the mature mRNA. The presence of the PTC subsequently triggers the cellular quality control mechanism known as Nonsense-Mediated mRNA Decay (NMD), leading to the rapid degradation of the faulty mRNA transcript.
[0045] In some embodiments, RNA or DNA molecules can use the same target sequence as the antisense oligonucleotides (ASOs) herein. Such embodiments can involve different types of RNAs, for which molecular mechanisms for RNA modifications other than those discussed for phosphorodiamidate morpholino oligomers (PMOs) can be, without being bound by theory, inducing the RNase Hl endonuclease activity that cleaves RNA-DNA hybrids on mRNA, RNA-Induced Silencing Complex (RISC), destabilizing pre-mRNA by inhibiting 5' cap formation / modulating 3' polyadenylation, or any combination thereof. In some embodiments, ASOs can target miRNAs and inhibit their RISC-dependent action to reduce protein translation.
[0046] In some embodiments, a relatively shorter length can reduce specificity or might cause off-target effect, while it can be more advantageous such as that more targeting sites can be identified. In some embodiments, a relatively longer length can increase specificity and can have a relatively lower target effect, e.g., due to binding kinetics, obstructions, etc. In some embodiments, a relatively longer length can be hindered by relatively limited target sites because of the secondary structures in DNA, pre-mRNA or mRNA.
[0047] In some embodiments, OPN or SPP1 is involved in multiple functions in cellular activities. SPP1 also known as Osteopontin (OPN), is a highly phosphorylated sialoprotein. In some embodiments, OPN is now considered as a regulator of diversified biological events,including developmental processes, wound healing, immunological responses, tumorigenesis, bone resorption, and calcification. In some embodiments, OPN is expressed in a variety of tissues indicates a multiplicity of functions. In some embodiments, in tumor microenvironment and some autoimmune diseases, macrophages are the major source of OPN. Thus, modulating OPN expression by the products described herein may be used in treating or preventing diseases.
[0048] For example, in some embodiments, delivering oligonucleotides such as ASOs and PMOs as therapeutics involves an approach to overcome biological barriers and ensure efficient targeting. In some embodiments, oligonucleotide delivery as therapeutics, such as ASOs and PMOs, can be achieved through various strategies to enhance their stability, cellular uptake, and target specificity. In some embodiments, it may involve chemical modifications to enhance stability and pharmacokinetics, conjugation techniques to improve cellular uptake and tissue targeting, and the use of nanocarrier systems for protection and delivery. In some embodiments, chemical modifications like phosphorothioate backbones, 2'-O-methyl sugars, and 5 -methylcytosine bases improve the oligonucleotides' drug-like properties. In some embodiments, chemical modifications, such as the introduction of phosphorothioate linkages or 2'-O-methyl groups, can improve the oligonucleotides' resistance to nuclease degradation. In some embodiments, conjugation strategies, such as GalNAc for liver targeting and cell-penetrating peptides for enhanced cellular uptake, have proven effective. In some embodiments, conjugation with cell-penetrating peptides (CPPs) like DG9 or R6G can significantly enhance cellular uptake and intracellular distribution. In some embodiments, nanocarrier systems, including lipid nanoparticles (LNPs) and polymeric nanoparticles, offer protection and improved delivery, with LNPs being particularly successful in approved therapies. In some embodiments, nanocarrier systems, including liposomes, polymeric nanoparticles, or lipid nanoparticles, can be employed to protect the oligonucleotides from degradation and facilitate their delivery to target tissues. For PMOs, which are charge-neutral, conjugation with CPPs is particularly effective in improving their cellular absorption. In some embodiments, targeted delivery can be achieved by incorporating ligands such as antibodies, aptamers, or small molecules that recognize specific cell surface receptors. In some embodiments, for a choice of delivery method, specific oligonucleotide properties, target tissue, and desired therapeutic effect, with the ultimate goal of maximizing efficacy while minimizing off-target effects and toxicity, etc., can be considered. In some aspects, the techniques described herein relate to a pharmaceutical composition including the compound and a pharmaceutically acceptable diluent, carrier, salt or adjuvant.I. Definitions

Unlike other types of antisense oligonucleotides (ASOs) or siRNA, PMOs are relatively uncharged nucleic acid analogs, which can be relatively more or highly stable and resistant to a variety of enzymes present in biologic fluids. In some embodiments, PMOs can bind to complementary sequences of target mRNA to block protein translation through steric blockade in a RNase H independent manner. In some embodiments, PMOs can bind to complementary sequences of target pre-mRNA to prevent productive RNA splicing. In some embodiments, PMOs can be relatively neutral charge and may not relatively bind to proteins.
[0075] In some embodiments, PMOs can be designed or screened based on at least one of various types of methods. For example, in some embodiments, primary PMO candidate sequences can be confirmed by in vitro studies. For example, in some embodiments, Western-blot and ELISA data can be implemented and used for screening of PMOs.
[0076] In some embodiments, PMOs can be conjugated with one or more molecules, e.g., to form PMO conjugates. In some embodiments, PMOs can be conjugated with at least one of different types of molecules, e.g., to form PMO conjugates. In some embodiments, PMOscan be conjugated with one or more different types of molecules, e.g., to form PMO conjugates. In some embodiments, PMOs can be conjugated with different types of molecules, e.g., to form conjugated PMOs, such as Antisense PMO and Cell penetrating peptide (CPP), etc
[0077] In some embodiments, cell penetrating peptides (CPPs) can be designed or screened. For example, in some embodiments, using one primary PMO candidate, CPPs can be conjugated to generate peptide-conjugated PMOs (PPMOs). For example, in some embodiments, conjugated PPMOs were screened in vitro, e.g., by using at least one technique to test for cell uptake, cytotoxicity, and protein reduction. In some embodiments, Westernblot and ELISA data can be utilized for the testing.
[0078] For example, in some embodiments, the following PMOs as indicated in Table 1 were identified based on the disclosure of the present application.TABLE 1Sequence Length
[0079] In some embodiments, the sequence length that can be relatively effective can depend on modality.
[0080] In some embodiments, the length of ASO (single strand) can be from 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41 , 42, 43, 44, 45, 46, 47, 48, 49 or about 50 nucleotides. In some embodiments, the length of ASO (single strand) can be from 5 to about 35. In some embodiments, the length of ASO (single strand) can be from 10 to about 30.
[0081] In some embodiments, the length of PMO (morpholino, one type of ASOs) can be from 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49 or about 50 nucleotides. In some embodiments, the length of PMO (morpholino, one type of ASOs) can be from 5 to about 35. In some embodiments, the length of PMO (morpholino, one type of ASOs) can be from 10 to about 30.
[0082] In some embodiments, the length of PMO (morpholino, one type of ASOs) can work in a shorter form such as about 14 to about 15.
[0083] In some embodiments, the length of ASO, such as PMO, can be from about 8 to about 40. In some embodiments, it can be relatively more practical if the length of ASO, such as PMO, can be from about 5 to about 40 nucleotides. In some embodiments, the length of ASO, such as PMO, can be relatively more preferably from about 12 to about 30. In some embodiments, the length of ASO, such as PMO, can be relatively more preferably from about 18 to about 28, e.g., in the case of ASO being PMO.
[0084] In some embodiments, the length of ASO such as morpholino, (one type of ASOs, but not limiting on this application) can be about 24 to about 40 nucleotides. In some embodiments, this length can relatively efficiently invade most secondary structures in mRNAs. In some embodiments, this can be a consequence of at least one of the following two factors. First, each Morpholino can be sufficiently long (25-mer) that it has a high probability of being complementary to some single-stranded segment of the target sequence -and this helps to assure efficient nucleation of pairing in spite of the extensive secondary structures characteristic of RNAs in the cell. Second, Morpholinos can have a high affinity for RNA (far higher than the affinity of S-DNA for RNA), and this high affinity allows the Morpholino to efficiently invade any secondary structures which the target sequence might be a part of. Thus, their extended length helps assure effective nucleation of pairing to the target sequence, and their high affinity helps assure that this nucleated pairing progresses to successful invasion of any proximal secondary structures which might be masking the target sequence.

The condition of the airway or lung may further involve inflammation-induced fibrosis or chronic respiratory distress associated with fibrotic tissue remodeling. In any aspect, the ASOs (or RNA or DNA molecules) are administered to the total respiratory tract, the upper respiratory tract or the lower respiratory tract.Dosage
[0131] In some embodiments, the ASO (or RNA or DNA molecules) as described herein dosage may be expressed as the amount of the compound that results in amelioration of symptoms or a prolongation of survival in a patient. Toxicity and therapeutic efficacy of the ASO (or RNA or DNA molecules) can be determined by standard pharmaceutical procedures in cell cultures or experimental animals (e.g., for determining the LD50 — the dose lethal to 50% of the population) and the ED50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index, which can be expressed as the ratio between LD50 and ED50. Compounds exhibiting high therapeutic indices are preferred. The data obtained from cell culture assays and animal studies can be used in formulating a range of dosages or amounts for use in mammals (e.g., humans). The dosage or amount of an ASO (or RNA or DNA molecules) as described herein preferably lies within a range of circulating concentrations that include the ED50 with little or no toxicity. The dosage or amount may vary within this range depending upon the dosageform employed and the route of administration utilized. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition. Dosage amount and interval may be adjusted individually to provide plasma or target tissue levels of the active moiety which are sufficient to maintain the desired effects.
[0132] Dosages for a particular patient can be determined by one of ordinary skill in the art using conventional considerations, (e.g., by means of an appropriate, conventional pharmacological protocol). A physician may, for example, prescribe a relatively low dose at first, subsequently increasing the dose until an appropriate response is obtained. The dose administered to a patient is sufficient to effect a beneficial therapeutic response in the patient over time, or, e.g., to reduce symptoms, or other appropriate activity, depending on the application. The dose can be determined by the efficacy of the particular formulation, and the activity, stability or serum and / or tissue half-life of the ASOs (or RNA or DNA molecules) as described herein employed and the condition of the patient, as well as the body weight or surface area of the patient to be treated. The size of the dose can also be determined by the existence, nature, and extent of any adverse side-effects that accompany the administration of a particular composition in a particular patient.
[0133] Optimal precision in achieving effective ASOs (or RNA or DNA molecules) as described herein concentrations within a range yielding maximum efficacy with minimal toxicity may require a regimen based on the kinetics of the pharmaceutical composition's availability to the targeted heart tissues or lung tissues. Distribution, equilibrium, and elimination of a pharmaceutical composition may be considered when determining the optimal concentration for a treatment regimen. Generally, the pharmaceutical compositions of the present invention may be administered in a manner that maximizes efficacy and minimizes toxicity.
[0134] Moreover, the dosage administration of the compositions of the present invention may be optimized using a pharmacokinetic / pharmacodynamic modeling system. For example, one or more dosage regimens may be chosen and a pharmacokinetic / pharmacodynamic model may be used to determine the pharmacokinetic / pharmacodynamic profile of one or more dosage regimens. Next, one of the dosage regimens for administration may be selected which achieves the desired pharmacokinetic / pharmacodynamic response based on the particular pharmacokinetic / pharmacodynamic profile. See, e.g., US 6,747,002, which is entirely expressly incorporated herein by reference.
[0135] More specifically, the ASO(s) or RNA or DNA molecules as described herein of the present application are preferably administered intermittently, such as once every two days, twice weekly, once weekly, biweekly, monthly, or every two to six months. However, the compositions may also be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily to achieve a loading dose or for maintenance therapy. The composition is formulated for administration by injection, including, but not limited to, intravenous, subcutaneous, intramuscular, or specific organ injection (e.g., targeted pulmonary delivery). The total daily dosage of the composition may be varied over a wide range from about 0.001 mg to about 1,000 mg per patient, per administration (where an administration may be daily or intermittent). The dose may more particularly be expressed in terms of body weight, ranging from about 0.001 mg / kg to about 10 mg / kg or up to lOOmg / kg of body weight per administration.
[0136] The dosage of the ASO(s) or RNA or DNA molecules as described herein of the present application may be varied over a wide range from about 0.1 pg to about 1000 mg per adult human per day, or per week, or per month, or per quarter. For oral or targeted pulmonary administration (e.g., nebulization) administration, the compositions may be provided in dosages from about 0.1 pg to about 1000 mg of the composition or 0.1, 0.2, 0.5, 1.0, 2.0, 5.0, 10.0, 15.0, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 800, 900, or 1000 milligrams of the composition for the symptomatic adjustment of the dosage to the patient to be treated. An effective amount of the pharmaceutical composition is ordinarily supplied at a dosage level of from about 0.1 pg / kg to about 20 mg / kg of body weight per day, or per week, or per month, or per quarter. In one embodiment, the range is from about 0.2 pg / kg to about 10 mg / kg of body weight per day. In another embodiment, the range is from about 0.5 pg / kg to about 10 mg / kg of body weight per day, or per week, or per month, or per quarter. The pharmaceutical compositions may be administered on a regimen of about 1 to about 10 times per day or per week, or per month, or per quarter.
[0137] In the case of injections, it is usually convenient to give by an intravenous route or via a subcutaneous route in an amount of about 0.01 pg-30 mg / kg, about 0.01 pg-20 mg / kg or about 0.01-10 mg / kg per day, or per week, or per month, or per quarter to adults (at about 60 kg).

[0192] EXAMPLE 11 : PPMO activities in human cellsReagents
[0193] Peptide-morpholino conjugates (PPMOs). The conjugation and purification of SPP1 -targeted PMOs to the P7, R6B or RGD peptide was performed using published methods (Abes et al., J. Control Release (2006) 1;116(3):304-l 3). The identity of each PPMO was confirmed by electrospray mass spectrometry.
[0194] Three PPMO candidates were used, each conjugated to a specific peptide (P7, R6B, or RGD), corresponding to PPMO#1, PPMO#2, and PPMO#3, respectively. The agents were shipped as dry lyophilized powder and stored at -20°C. The working solution was prepared at ImM concentration by adding PBS and then stored at 4C. U-251 cells were cultured with DMEM medium with 10% FBS, and 1U penicillin / streptomycin (Gibco 15070-063).Western-blot
[0195] U251 cells were seeded into each well of 12-well plates with 250,000 cells / ml / well cell’s density one day before assay. After 24h, cell culture medium was removed and 800ul fresh medium was added per well. 5X PPMO was prepared by adding appropriate volume of PPMO stock solution. 200ul 5X PPMO was added per well. After another 24 hours, cells were harvested using 0.25% Trypsin-EDTA. The harvested cells were washed with 1XPBS, resuspended with lOOul lysis buffer (Pierce RIPA lysis buffer, Cat: 89901). Following the instruction of Lysis collection, then protein concentration of each sample was measured by BCA test (Pierce BCA Protein Assay, Cat: 23227) and read by a Perkin Elmer Wallac 1420 Victor2 Microplate Reader.
[0196] A total 20ug / per sample was analyzed by SDS page (Invitrogen, NuPage 4-12% Bis-tris Gel, Cat: NP0322BOX) (120V lOmin and 175V 30min). After transferred the proteins onto the nitrocellulose blotting membrane with semi-dry Trans-Blot (15 Voltage for 35min, Invitrogen iBlot2 PVDF Cat: IB24002) by iBlot2 (invitrogen), the membrane was then blocked with 5% milk / TBST for 1.5h. Then the membrane was detected with the primary human anti-OPN antibody (1:2500 at 4C overnight, Abcam / #ab214050). After 4x TBST wash, membrane was detected with anti-rabbit IgGHRP (1:5000, RT 1 hour, RPL / #95059-086). After developing the image with substrate from Pierce ECL WB Substrate (Cat: 32209), membrane was washed 4x TBST and detected with anti-Actin (1:5000, 40 min RT, Santa Cruz Cat: sc-47778 HRP). Images were taken by using Azure 280.ELISA
[0197] 20,000 U251 cells per well were seeded into 96 well cell culture plates. After 24 hours, cell culture medium was removed and 80ul fresh medium was added per well. 5X PPMO was prepared by adding appropriate volume of PPMO stock solution. 20ul 5X PPMOwas added per well. After another 24 hours, supernatants of cell culture were collected for ELISA (R&D system, Cat: DOSTOO). ELISA procedures followed the instruction of the manufacturer. ELISA plates were read by a Perkin Elmer Wallac 1420 Victor2 Microplate Reader or a Tecan Infinite M200 reader.Results
[0198] Referring to FIG. 17 and FIG. 18, lOuM P7-PPMO (PPMO#1) reduced the production of SPP1 in both cell lysis (FIG. 17) and cell culture medium (FIG. 18). Under this testing condition, rest PPMOs did not show obvious reduction of SPP1 protein production in human U-251 cells, which is consistent with cell uptake results (see Fig. 14).
[0199] Since the study shown in FIG. 17 and FIG. 18 demonstrated the knockdown effects on SPP1 production by PPMOs in 12-well cell culture system, a semi-high throughput method by ELISA in a 96-well cell culture system was used to quantify the knockdown effects. Referring to FIG. 19, 5uM P7-PPMO (PPMO#1) reduced 60% of SPP1 secretion in cell culture medium. R6B-PPMO (PPMO#2), which is less effective, reduced 35% of SPP1 secretion in U-251 cells.
[0200] Cell Uptake: In in vitro cellular uptake assays, PPMO#1 exhibited relatively stronger uptake efficiency when compared to PPMO#2 and PPMO#3. FIG. 14 and FIG. 15 shows the cellular internalization of peptide-conjugated phosphorodiamidate morpholino oligonucleotide (PPMO) Hu-01 across three peptide constructs by U-251 cells and Hela cells, respectively. The PMO Hu-01 was covalently linked to fluorescein and one of three targeting moieties: PPMO #1 (P7 peptide), PPMO #2 (R6B peptide), or PPMO #3 (RGD peptide). Following a 24-hour incubation, the cell-associated fluorescence of the unconjugated (fluorescein-labeled) Hu-01 and the three PPMOs was measured via flow cytometry. Mean Fluorescence Intensity (MFI) was used to evaluate cellular uptake, with results for 5pM and lOpM concentrations presented for comparative analysis.
[0201] FIG. 16 shows the cytotoxicity of different PPMOs in U-251 cells. 5000 U-251 cells / well were seeded into a 96-well cell culture plate. After 24 hours, cells were incubated with indicated concentrations of PMO Hu-01 and three different peptide conjugated PMOs (PPMO #l-#3). After another 24 hours, cell viability was examined with a CellTiter-Glo kit (commercial kit (Promega).
[0202] FIG. 17 shows the biological effect of three peptide-conjugated PMOs (PPMOs) on OPN production in U-251 cells. U251 cells were seeded into each well of 12-well plates with 250,000 cells / lml medium per well. After 24 hours, U-251 cells were treated with indicated concentrations of PPMO #1, #2, and #3, and three corresponding scrambled PMO controls (conjugated with P7, R6B, and RGD, respectively), along with the unconjugated PMO Hu-01. Following 24-hour incubation, cell lysates were collected and assayed for OPN production using a Human OPN detection ELISA Kit (top). Results were quantified using 5 pg of cell lysate per well (measured in duplicate, n=2). The data shown represent the mean of the duplicate measurements.
[0203] FIG. 18 shows the biological effect of three peptide-conjugated PMOs (PPMOs) on OPN production in U-251 cells. U251 cells were seeded into each well of 12-well plates with 250,000 cells / lml medium per well. After 24 hours, U-251 cells were treated with indicated concentrations of PPMO #1, #2, and #3, and three corresponding scrambled PMO controls (conjugated with P7, R6B, and RGD, respectively), along with the unconjugatedPMO Hu-01. Following 24-hour incubation, cell culture media were collected and assayed for OPN production using a Human OPN detection ELISA Kit (top). Results were quantified using 1:20 diluted cell culture supernatants (measured in duplicate, n=2). The data shown represent the mean of the duplicate measurements.
[0204] FIG. 19 shows the biological effect of PPMO #1 (P7 peptide conjugated PMO Hu-01) and PPMO #2 (R6B peptide conjugated PMO Hu-01) on OPN production in U-251 cells.20,000 U-251 cells per well were seeded into 96 well cell culture plates. After 24 hours, cell culture medium was removed, and fresh medium containing indicated concentrations of PPMOs was added. Following 24-hour incubation, cell culture media were collected and assayed for OPN production using a Human OPN detection ELISA Kit. Results were quantified using 1:20 diluted cell culture supernatants. Each condition was quadruplicated and data represented as mean ± SEM.
[0205] In summary, these results indicate that peptide conjugation represents an effective approach to enhance intracellular delivery of oligonucleotides. The data further show an association between the extent of cellular uptake and the resulting biological activity, as reflected by reduced target protein production. Among the tested PPMOs, PPMO#1 and PPMO#2 demonstrated excellent inhibition of target protein expression at the translational level, which is consistent with their higher intracellular uptake observed under the experimental conditions. These findings also show that the delivery-enhancing effect of peptide conjugation is not limited to the particular peptide sequences evaluated here and may extend to other peptide architectures or variants.
[0206] EXAMPLE 12: Oligo Activity EnhancerReagents
[0207] Two PPMO candidates (PPMO #1 and PPMO #2) recognizing human SPP1 were generated. They were shipped as dry lyophilized powder and stored at -20C. The working solution was prepared at ImM concentration by adding PBS and then stored at 4C. OAEs were prepared and shipped as dry lyophilized powder and stored at -20C.
[0208] U-251 cells were cultured with DMEM medium with 10% FBS, and 1U penicillin / streptomycin (Gibco 15070-063).ELISA
[0209] 5 ,000-20,000 U251 cells per well were seeded into 96 well cell culture plates. After 24 hours, cell culture medium was removed and 90ul fresh medium was added per well.5ul 20X PPMO and / or 5ul 20X OAE or 5ul PBS were added per well to make a final volume lOOul. After another 24 hours, supernatants of cell culture were collected for ELISA (R&D system, Cat: DOST00).Results
[0210] Small molecules can enhance nucleic acid (NA) delivery by promoting endocytosis and facilitating endosomal escape, allowing NAs to enter the cytosol and function more efficiently. Such small molecules can be defined as Oligo Activity Enhancer (OAE). The study tested lonafarnib (OAE2) with the SPP1 -targeted PPMO candidate(PPMO#1). OAE2 demonstrated a synergistic effect with PPMO#1 in disrupting / reducing target protein production. (FIG. 20).
[0211] FIG. 21 shows the cytotoxicity of the combination of fixed concentration of PPMO #1 and a variety of concentrations of Oligo Activity Enhancer (OAE 2) in Hela cells (left) and U-251 cells (right). 15 000 Hela cells / well or 5000 U-251 cells / well were seeded in 96-well cell culture plates After 24 hours, cells were treated with a combination of 10 uM PPMO #1 and indicated concentrations of OAE 2. After 24 hours, cell viability was examined with a CellTiter-Glo kit (commercial kit (Promega) Cell treatment were triplicated and data represented as mean ± SD.
[0212] In summary, these results indicate that small molecules which have RNA activity-enhancing functions, such as OAE2 (lonafamib), can enhance the activity of the candidate PPMOs.
[0213] EXAMPLE 13Formulation
[0214] A PPMO comprising a phosphorodiamidate morpholino oligomer covalently linked to a delivery peptide is formulated in a sterile, isotonic aqueous vehicle suitable for intratracheal delivery. The formulation is adjusted to a concentration such that the intended deposited dose is administered in a small bolus volume (for mice typically 50-100 pL).Animal Model
[0215] Adult C57BL / 6 mice (8-10 weeks old) are used. Pulmonary fibrosis is induced by a single intratracheal administration or oropharyngeal instillation of bleomycin (e.g., 1-2 mg / kg) on Day 0. Animals are randomized to treatment or control groups.Administration
[0216] The PPMO is delivered directly to the lower respiratory tract by intratracheal administration under brief anesthesia, using standard techniques such as nebulization (via a specialized device or needle) or orotracheal intubation (with a fine catheter or specialized microsprayer).Single-dose regimen
[0217] One intratracheal bolus of PPMO is administered on Day 3, or day 7 postbleomycin. The deposited dose is an estimated 1-10 mg / kg (mouse equivalent), delivered in a single bolus volume (50-100 pL). Control animals receive vehicle or non-targeting PPMO.Two-dose regimen
[0218] Two intratracheal boluses of PPMO are administered. The first dose is given on Day 3 (or Day 7) post-bleomycin challenge, and the second dose is administered on Day 10 post-bleomycin challenge. Each administration delivers an estimated deposited dose of 0.5-5 mg / kg per dose (total cumulative dose 1-10 mg / kg). Control animals receive two administrations of vehicle or non-targeting PPMO according to the same schedule.Assessment / Endpoints
[0219] At Day 21 (or another selected terminal time point), animals are euthanized and lungs harvested for analysis. Example endpoints include, but are not limited to:
[0220] 1. Target engagement: Reduction of OPN mRNA or protein in lung tissue (qRT- PCR, western blot, or hybridization assay).
[0221] 2. Histopathology: H&E and Masson’s tri chrome staining with semi-quantitative fibrosis scoring (e.g., modified Ashcroft score).
[0222] 3. Collagen content: Hydroxyproline assay to quantify total lung collagen.
[0223] 4. Inflammation / fibrosis biomarkers: Measurement of markers such as a-SMA, COL1A1, TGF-pi by IHC, ELISA, or qPCR.
[0224] 5. Clinical parameters: Body weight, lung weight, and clinical observations recorded during the study.
[0225] 6. Biodistribution / toxicity (optional): Assessment of PPMO distribution in major organs and basic toxicology endpoints (serum chemistry, organ histology).
[0226] Outcome
[0227] Intratracheal delivery of the disclosed PPMO (single or two administrations) results in efficient delivery to lung parenchymal cells, reduction of the designated target, and an observable decrease in fibrotic markers and collagen deposition relative to controls. The two-dose regimen provides extended target suppression in comparing with a single bolus, though single administration is sufficient depending on compound potency and pharmacodynamics.
[0228] Using alternative intratracheal devices (specialized needles, nebulization devices, microsprayers, fine catheters), alternative species (e.g. rat), varied dose ranges, administration schedules (e.g., repeated dosing beyond two doses), and alternative fibrosis induction models is also effective.
