Sarepta Therapeutics Announces Second Quarter 2020 Financial Results and Recent Corporate Developments

– Net product sales of $111.3 million, an 18% increase over same quarter of prior year –

CAMBRIDGE, Mass., Aug. 05, 2020 (GLOBE NEWSWIRE) -- Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, today reported financial results for the second quarter of 2020.

“I am pleased to report that, notwithstanding the distracting nature of the COVID-19 pandemic, Sarepta has continued to serve our patient community, achieving net product sales of $111.3 million, an 18% increase over the same quarter last year. And even as the majority of our workforce continued in a work-from-home environment, we have remained on mission and productive. We have already attained or remain on track to attain our many planned 2020 milestones, have deepened and extended the three pillars of our enduring gene therapy engine, and with additional data generated this year, continue to validate our unique and differentiated approach to building a gene therapy platform,” said Doug Ingram, Sarepta’s president and chief executive officer. “Regarding our RNA platform, in the second quarter we completed our rolling New Drug Application (NDA) for our third PMO candidate, casimersen and are on track to report the proof-of-concept results for our next-generation PPMO candidate in the second half of 2020. Regarding our gene therapy engine, we announced the publication of our positive one-year results for our first study of our gene therapy SRP-9001 to treat Duchenne muscular dystrophy (DMD), announced the positive expression and safety results for our high-dose cohort of LGMD2E patients treated with SRP-9003 and positive one-year functional results for our lower dose cohort treated with SRP- 9003, and are on track to commence our commercial process trial for SRP-9001 in the second half of 2020. We made great strides in gene therapy manufacturing this quarter, having now completed GMP runs for SRP-9001 using our commercial process, and commencing GMP runs for SRP-9003, to be completed by year end. And we entered into multiple partnerships to advance the science of gene therapy, including our agreements with Dyno Therapeutics, Selecta Biosciences, Codiak Biosciences and Hansa Biopharma.”

Second Quarter 2020 and Recent Corporate Developments:

• Positive safety and efficacy data from the SRP-9001 micro-dystrophin gene therapy trial published in JAMA Neurology: One year data from the four DMD clinical trial participants who received SRP-9001 (AAVrh74.MHCK7.micro-dystrophin) were published in JAMA Neurology. These data further support the potential for SRP-9001 to provide clinically meaningful functional improvements in terms of speed and magnitude of improvement for patients with DMD.
  
• Announced positive expression and functional data from the SRP-9003 gene therapy trial to treat limb-girdle muscular dystrophy type 2E (LGMD2E): These results included safety and expression data from three clinical trial participants in the high-dose cohort measured at 60 days, and one-year functional data from three clinical trial participants in the low-dose cohort. In post-treatment muscle biopsies, clinical trial participants in the high-dose cohort showed a dose-dependent increase in transduction and expression when compared with the low-dose cohort, with a mean of 72% beta-sarcoglycan (beta-SG) positive fibers, as measured by immunohistochemistry (IHC), substantially exceeding the pre-defined 50% measure for success. In the low-dose cohort, continued functional improvement was observed at one year.
  
• Completed submission of New Drug Application (NDA) seeking approval for casimersen (SRP-4045): The Company has completed the submission of a rolling NDA to the U.S. Food and Drug Administration (FDA) seeking accelerated approval for casimersen (SRP-4045). Casimersen, a phosphorodiamidate morpholino oligomer (PMO), is engineered to treat patients with DMD who have genetic mutations that are amenable to skipping exon 45 of the Duchenne gene.
  
• Signed agreement with Hansa Biopharma for imlifidase: Sarepta obtained an exclusive, worldwide license to develop and promote imlifidase as a pre-treatment to enable Sarepta gene therapy administration in DMD and limb-girdle muscular dystrophy (LGMD), for patients who have pre-existing IgG antibodies and are not currently eligible for treatment with any adeno-associated virus (AAV)-based gene therapies.
  
• Signed agreement with Codiak BioSciences, Inc., to use engEx™ platform to research and develop exosome-based therapies for rare diseases: This alliance will explore the utility of engineered exosomes developed with Codiak’s engEx™ platform to deliver gene therapy, gene editing and RNA technologies for neuromuscular diseases. Exosomes are natural nanoparticles that serve as the body’s intercellular communication system, facilitating the transfer of a wide variety of molecular payloads between cells. As they are derived from human cells, exosomes provide a unique advantage as a targeted delivery system for genetic medicines because they are inherently non-immunogenic.
  
• Signed agreement with Selecta Biosciences, Inc. for ImmTOR™ immune tolerance platform in neuromuscular diseases: This agreement grants Sarepta an option to license the rights to develop and commercialize Selecta’s immune tolerance platform, ImmTOR, for use in DMD and certain LGMDs. Currently, all systemic AAV-delivered constructs are one-time therapies that cannot be re-dosed due to the robust post-administration development of neutralizing antibodies (Nabs) specific to the AAV vector. Selecta is a leader in immune tolerance and has generated strong preclinical evidence to support the potential for re-dosing patients receiving gene therapy.
  
• Signed agreement with Dyno Therapeutics to use CapsidMap™ platform to develop next-generation gene therapy vectors for muscle diseases: This agreement leverages Sarepta’s leadership in gene therapy for neuromuscular and cardiovascular diseases and Dyno’s CapsidMap artificial intelligence platform to design AAV vectors. Dyno’s proprietary platform opens up new ways to identify novel capsids – the cell-targeting protein shell of viral vectors – that could offer improved muscle targeting and immune-evading properties, in addition to advantages in packaging and manufacturing.

Financial Results

On a GAAP basis, for the three months ended June 30, 2020 and 2019, the Company reported a net loss of $150.8 million and $276.4 million, or $1.93 and $3.74 per basic and diluted share, respectively. On a non-GAAP basis, the net loss for the second quarter of 2020 was $117.9 million, or $1.51 per basic and diluted share, compared to a net loss of $61.2 million, or $0.83 per basic and diluted share for the same period of 2019.

On a GAAP basis, for the six months ended June 30, 2020, the Company reported a net loss of $168.3 million, or $2.18 per basic and diluted share, compared to a net loss of $353.0 million reported for the same period of 2019, or $4.85 per basic share and diluted share. On a non-GAAP basis, the net loss for the six months ended June 30, 2020 was $197.7 million, or $2.56 per basic and diluted share, compared to a net loss of $115.0 million for the same period of 2019, or $1.58 per basic and diluted share.

Revenues

For the three months ended June 30, 2020, the Company recorded net product revenues of $111.3 million, compared to net product revenues of $94.7 million for the same period of 2019, an increase of $16.6 million. For the six months ended June 30, 2020, the Company recorded net product revenues of $211.8 million, compared to net product revenues of $181.7 million for six months ended June 30, 2019, an increase of $30.1 million. The increase primarily reflects the continuing increase in demand for the Company’s products in the U.S.

In the three and six months ended June 30, 2020, the Company recognized $26.0 million and $39.2 million of collaboration revenue, respectively, which primarily relates to the Company’s collaboration arrangement with F. Hoffman-La Roche Ltd. (“Roche”). In February 2020, the Company received an aggregate of approximately $1.2 billion in cash consideration from Roche, consisting of an up-front payment and an equity investment in the Company. Of that amount, $348.7 million is being recognized as revenue on a straight-line basis over the performance period, estimated to be through the fourth quarter of 2023.

Cost and Operating Expenses

Cost of sales (excluding amortization of in-licensed rights)
For the three months ended June 30, 2020, cost of sales (excluding amortization of in-licensed rights) was $13.3 million, compared to $15.9 million for the same period of 2019, a decrease of $2.6 million. For the six months ended June 30, 2020, cost of sales (excluding amortization of in-licensed rights) was $26.0 million, compared to $28.0 million for the same period of 2019. The decrease in inventory costs related to products sold is primarily due to write-offs of certain batches of EXONDYS 51 not meeting the Company’s quality specifications for the three months ended June 30, 2019, with no similar activity for the three months ended June 30, 2020. This decrease was partially offset by an increase in demand for the Company’s products and an increase in royalty payments to BioMarin Pharmaceuticals (“BioMarin”) and University of Western Australia (“UWA”) as a result of increasing demand for the Company’s products.

Research and development

Research and development expenses were $188.5 million for the three months ended June 30, 2020, compared to $113.3 million for the same period of 2019, an increase of $75.2 million. The increase in research and development expenses primarily reflects the following:

• $81.6 million increase in manufacturing expenses primarily due to a continuing ramp-up of the Company’s micro-dystrophin program;
• $4.6 million increase in compensation and other personnel expenses primarily due to a net increase in headcount;
• $4.2 million increase in stock-based compensation expense primarily driven by increases in headcount and stock price;
• $1.9 million increase in facility- and technology-related expenses due to the Company’s continuing global expansion efforts;
• $1.5 million increase in collaboration cost sharing with Genethon on its micro-dystrophin drug candidates and Lysogene S.A on its MPS IIIA drug candidates;
• $1.1 million decrease in professional service expenses primarily due to a decrease in reliance on third-party research and development contractors as a result of an increase in hiring and headcount;
• $2.3 million decrease in up-front, milestone and other expenses primarily due to $12.0 million of up-front payments as a result of the execution of certain research and license agreements during the second quarter of 2020, offset by $14.4 million of similar activity during the second quarter of 2019;
• $6.5 million decrease in clinical trial expenses primarily due to a ramp-down of the PROMOVI trial in EXONDYS 51 and the Phase 1/2 trial in golodirsen. The decreases were offset by increased patient enrollment for the Company’s ESSENCE program as well as certain start-up activities for the Company’s micro-dystrophin program; and
• $8.8 million offset to expense incurred in the second quarter of 2020 associated with a collaboration reimbursement from Roche.

Research and development expenses were $324.7 million for the six months ended June 30, 2020, compared to $203.8 million for the same period of 2019, an increase of $120.9 million. The increase in research and development expenses primarily reflects the following:

• $123.3 million increase in manufacturing expenses primarily due to a continuing ramp-up of the Company’s micro-dystrophin program;
• $11.0 million increase in compensation and other personnel expenses primarily due to a net increase in headcount;
• $8.4 million increase in stock-based compensation expense primarily driven by increases in headcount and stock price;
• $5.1 million increase in up-front, milestone and other expenses primarily due to $8.8 million of milestone expense related to payments accrued to an academic institution and $12.0 million of up-front payments as a result of the execution of certain research and license agreements during the six months ended June 30, 2020, offset by $15.5 million of up-front payments as a result of license agreements executed during the same period of 2019;
• $4.0 million increase in facility- and technology-related expenses due to the Company’s continuing global expansion efforts;
• $3.9 million increase in collaboration cost sharing with Genethon on its micro-dystrophin drug candidates and Lysogene S.A on its MPS IIIA drug candidates;
• $1.2 million increase in research and other primarily driven by an increase in sponsored research with academic institutions during the six months ended June 30, 2020;
• $1.1 million decrease in professional service expenses primarily due to a decrease in reliance on third-party research and development contractors as a result of an increase in hiring and headcount;
• $4.8 million decrease in pre-clinical expenses primarily due to completion of certain toxicology studies in the Company’s PPMO platform;
• $4.9 million decrease in clinical trial expenses primarily due to a ramp-down of the PROMOVI trial in EXONDYS 51 and the Phase 1/2 trial in golodirsen. The decreases were offset by an increase patient enrollment for the Company’s ESSENCE program as well as certain start-up activities for the Company’s micro-dystrophin program; and
• $25.2 million offset to expense associated with a collaboration reimbursement from Roche during the six months ended June 30, 2020.

Non-GAAP research and development expenses were $160.4 million and $87.5 million for the three months ended June 30, 2020 and 2019, respectively, an increase of $72.9 million. Non-GAAP research and development expenses were $274.6 million and $168.9 million for the six months ended June 30, 2020 and 2019, respectively, an increase of $105.7 million.

Selling, general and administration
Selling general and administrative expenses were $73.7 million for the three months ended June 30, 2020, compared to $67.4 million for the same period of 2019, an increase of $6.3 million. The increase in selling, general and administrative expenses primarily reflects the following:

• $3.6 million increase in stock-based compensation primarily due to increases in headcount and stock price; and
• $0.9 million increase in compensation and other personnel expenses primarily due to a net increase in headcount.

Selling general and administrative expenses were $156.5 million for the six months ended June 30, 2020, compared to $128.0 million for the same period of 2019, an increase of $28.5 million. The increase in selling, general and administrative expenses primarily reflects the following:

• $14.3 million increase in professional services primarily due to a transaction fee for the Roche transaction and continuing global expansion;
• $7.4 million increase in stock-based compensation primarily due to increases in headcount and stock price;
• $3.2 million increase in compensation and other personnel expenses primarily due to a net increase in headcount; and
• $1.2 million increase in facility- and technology-related expense primarily due to continuing global expansion.

Non-GAAP selling, general and administrative expenses were $55.1 million and $52.3 million for the three months ended June 30, 2020 and 2019, respectively, an increase of $2.8 million. Non-GAAP selling, general and administrative expenses were $109.6 million and $100.1 million for the six months ended June 30, 2020 and 2019, respectively, an increase of $9.5 million.

Acquired in-process research and development

As a result of the Myonexus acquisition, the Company recorded acquired in-process research and development expense of approximately $173.2 million during the second quarter of 2019. There was no such transaction during the six months ended June 30, 2020.

Amortization of in-licensed rights
For both the three months ended June 30, 2020 and 2019, the Company recorded amortization of in-licensed rights of approximately $0.2 million. For the six months ended June 30, 2020 and 2019, the Company recorded amortization of in-licensed rights of approximately $0.3 million and $0.4 million, respectively. This is related to the amortization of the in-licensed right assets recognized as a result of agreements the Company entered into with BioMarin and UWA upon the first commercial sale of EXONDYS 51 and VYONDYS 53.

Gain from Sale of Priority Review Voucher

In February 2020, the Company entered into an agreement with Vifor (International) Ltd. to sell the rare pediatric disease Priority Review Voucher (“PRV”) it received from the FDA in connection with the approval of VYONDYS 53. Following the early termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, in March 2020, the Company completed its sale of the PRV and received proceeds of $108.1 million, net of commission, which was recorded as a gain from sale of the PRV as it did not have a carrying value at the time of the sale. There was no similar activity during the six months ended June 30, 2019.

Other expense, net

For the three months and six months ended June 30, 2020, other expense, net was approximately $12.4 million and $19.9 million, respectively. For the three and six months ended June 30, 2019, other expense, net was approximately $0.9 million and $1.0 million, respectively. The increase primarily reflects the interest expense on the Company’s debt facilities entered into in December 2019 as well as a decrease in interest income and the amortization of investment discounts due to the investment mix of the Company’s investment portfolio.

Cash, Cash Equivalents, Investments and Restricted Cash and Investments

The Company had approximately $2.1 billion in cash, cash equivalents and investments as of June 30, 2020 compared to $1.1 billion as of December 31, 2019. The increase is primarily driven by the $1.2 billion up-front payments received from the Roche collaboration and equity investment offset by cash used to fund the Company’s ongoing operations during 2020.

Use of Non-GAAP Measures

In addition to the GAAP financial measures set forth in this press release, the Company has included certain non-GAAP measurements. The non-GAAP loss is defined by the Company as GAAP net loss excluding interest expense/(income), income tax expense/(benefit), depreciation and amortization expense, stock-based compensation expense and other items. Non-GAAP research and development expenses are defined by the Company as GAAP research and development expenses excluding depreciation and amortization expense, stock-based compensation expense and other items. Non-GAAP selling, general and administrative expenses are defined by the Company as GAAP selling, general and administrative expenses excluding depreciation and amortization expense, stock-based compensation expense and other items.

1. Interest, tax, depreciation and amortization

Interest income and expense amounts can vary substantially from period to period due to changes in cash and debt balances and interest rates driven by market conditions outside of the Company’s operations. Tax amounts can vary substantially from period to period due to tax adjustments that are not directly related to underlying operating performance. Depreciation expense can vary substantially from period to period as the purchases of property and equipment may vary significantly from period to period and without any direct correlation to the Company’s operating performance. Amortization expense associated with in-licensed rights as well as patent costs are amortized over a period of several years after acquisition or patent application or renewal and generally cannot be changed or influenced by management.

2. Stock-based compensation expenses

Stock-based compensation expenses represent non-cash charges related to equity awards granted by Sarepta. Although these are recurring charges to operations, the Company believes the measurement of these amounts can vary substantially from period to period and depend significantly on factors that are not a direct consequence of operating performance that is within the Company’s control. Therefore, the Company believes that excluding these charges facilitates comparisons of the Company’s operational performance in different periods.

3. Other items

The Company evaluates other items of expense and income on an individual basis. It takes into consideration quantitative and qualitative characteristics of each item, including (a) nature, (b) whether the items relate to the Company’s ongoing business operations, and (c) whether the Company expects the items to continue on a regular basis. These other items include collaboration revenue and transaction cost related to the Roche transaction, up-front and milestone payments, acquired in-process research and development expense and gain from sale of PRV.

The Company excludes collaboration revenue and transaction cost associated with the Roche transaction from its non-GAAP results. While collaboration revenue is recurring, as the Company’s ordinary activities do not include contracting with third parties to provide them with research and development services, collaboration revenue is treated as a non-GAAP item. Additionally, the transaction fee related to the Roche transaction is non-recurring and is excluded from its non-GAAP results. However, the Company does not exclude reimbursement of costs by Roche from its non-GAAP results.

The Company excludes up-front, milestone, and acquired in-process research and development expenses associated with its license and collaboration agreements from its non-GAAP results and research and development expenses because the Company does not consider them to be normal operating expenses due to their nature, variability of amounts, and lack of predictability as to occurrence and/or timing. Up-front payments are made at the commencement of a collaborative relationship or a license agreement anticipated to continue for a multi-year period and provide the Company with intellectual property rights, option rights and other rights with respect to particular programs. Milestone payments are made when certain development, regulatory and sales milestone events are achieved. The variability of amounts and lack of predictability of collaboration- and license-related up-front and milestone payment makes the identification of trends in the Company’s ongoing research and development activities more difficult.

As a result of the Myonexus acquisition, the Company recorded acquired in-process research and development expense, which represents a non-recurring expense and, therefore, was treated as a non-GAAP adjustment item. The Company believes the presentation of adjusted research and development, which does not include license- and collaboration-related up-front and milestone expenses, provides useful and meaningful information about its ongoing research and development activities by enhancing investors’ understanding of the Company’s normal, recurring operating research and development expenses and facilitates comparisons between periods and with respect to projected performance.

The sale of the PRV obtained as a result of the FDA approval of VYONDYS 53 in December 2019 is a non-recurring event and excluded from the Company’s non-GAAP results.

The Company uses these non-GAAP measures as key performance measures for the purpose of evaluating operational performance and cash requirements internally. The Company also believes these non-GAAP measures increase comparability of period-to-period results and are useful to investors as they provide a similar basis for evaluating the Company’s performance as is applied by management. These non-GAAP measures are not intended to be considered in isolation or to replace the presentation of the Company’s financial results in accordance with GAAP. Use of the terms non-GAAP research and development expenses, non-GAAP selling, general and administrative expenses, non-GAAP other income and loss adjustments, non-GAAP income tax expense, non-GAAP net loss, and non-GAAP basic and diluted net loss per share may differ from similar measures reported by other companies, which may limit comparability, and are not based on any comprehensive set of accounting rules or principles. All relevant non-GAAP measures are reconciled from their respective GAAP measures in the attached table "Reconciliation of GAAP Financial Measures to Non-GAAP Financial Measures.”

About EXONDYS 51

EXONDYS 51 uses Sarepta’s proprietary phosphorodiamidate morpholino oligomer (PMO) chemistry and exon-skipping technology to bind to exon 51 of dystrophin pre-mRNA, resulting in “skipping” of this exon during mRNA processing in patients with genetic mutations that are amenable to exon 51 skipping. Exon skipping is intended to allow for production of an internally truncated dystrophin protein.

EXONDYS 51 is indicated for the treatment of Duchenne muscular dystrophy in patients who have a confirmed mutation of the DMD gene that is amenable to exon 51 skipping.

This indication is approved under accelerated approval based on an increase in dystrophin production in skeletal muscle observed in patients treated with EXONDYS 51. Continued approval may be contingent upon verification of a clinical benefit in confirmatory trials.

EXONDYS 51 has met the full statutory standards for safety and effectiveness and as such is not considered investigational or experimental.

Important Safety Information About EXONDYS 51

Hypersensitivity reactions, including rash and urticaria, pyrexia, flushing, cough, dyspnea, bronchospasm, and hypotension, have occurred in patients who were treated with EXONDYS 51. If a hypersensitivity reaction occurs, institute appropriate medical treatment and consider slowing the infusion or interrupting the EXONDYS 51 therapy.

Adverse reactions in DMD patients (N=8) treated with EXONDYS 51 30 mg or 50 mg/kg/week by intravenous (IV) infusion with an incidence of at least 25% more than placebo (N=4) (Study 1, 24 weeks) were (EXONDYS 51, placebo): balance disorder (38%, 0%), vomiting (38%, 0%) and contact dermatitis (25%, 0%). The most common adverse reactions were balance disorder and vomiting. Because of the small numbers of patients, these represent crude frequencies that may not reflect the frequencies observed in practice. The 50 mg/kg once weekly dosing regimen of EXONDYS 51 is not recommended.

In the 88 patients who received ≥30 mg/kg/week of EXONDYS 51 for up to 208 weeks in clinical studies, the following events were reported in ≥10% of patients and occurred more frequently than on the same dose in Study 1: vomiting, contusion, excoriation, arthralgia, rash, catheter site pain, and upper respiratory tract infection.

About VYONDYS 53
VYONDYS 53 uses Sarepta’s proprietary phosphorodiamidate morpholino oligomer (PMO) chemistry and exon-skipping technology to bind to exon 53 of dystrophin pre-mRNA, resulting in exclusion, or “skipping,” of this exon during mRNA processing in patients with genetic mutations that are amenable to exon 53 skipping. Exon skipping is intended to allow for production of an internally truncated dystrophin protein.

VYONDYS 53 is indicated for the treatment of Duchenne muscular dystrophy in patients who have a confirmed mutation of the DMD gene that is amenable to exon 53 skipping.

This indication is approved under accelerated approval based on an increase in dystrophin production in skeletal muscle observed in patients treated with VYONDYS 53. Continued approval may be contingent upon verification of a clinical benefit in confirmatory trials.

VYONDYS 53 has met the full statutory standards for safety and effectiveness and as such is not considered investigational or experimental.

Important Safety Information for VYONDYS 53
Hypersensitivity reactions, including rash, pyrexia, pruritus, urticaria, dermatitis, and skin exfoliation have occurred in VYONDYS 53-treated patients, some requiring treatment. If a hypersensitivity reaction occurs, institute appropriate medical treatment and consider slowing the infusion or interrupting the VYONDYS 53 therapy.

Renal toxicity was observed in animals who received golodirsen. Although renal toxicity was not observed in the clinical studies with VYONDYS 53, renal toxicity, including potentially fatal glomerulonephritis, has been observed after administration of some antisense oligonucleotides. Renal function should be monitored in patients taking VYONDYS 53. Because of the effect of reduced skeletal muscle mass on creatinine measurements, creatinine may not be a reliable measure of renal function in DMD patients. Measurement of glomerular filtration rate (GFR) by 24-hour urine collection prior to initiation of therapy is recommended. Monthly monitoring for proteinuria by dipstick urinalysis and monitoring of serum cystatin C every three months is recommended. In the case of a confirmed dipstick proteinuria of 2+ or greater or elevated serum cystatin C, a 24-hour urine collection to quantify proteinuria and assess GFR should be performed.

Adverse reactions observed in at least 20% of treated patients and greater than placebo were (VYONDYS 53, placebo): headache (41%, 10%), pyrexia (41%, 14%), fall (29%, 19%), abdominal pain (27%, 10%), nasopharyngitis (27%, 14%), cough (27%, 19%), vomiting (27%, 19%), and nausea (20%, 10%).

Other adverse reactions that occurred at a frequency greater than 5% of VYONDYS 53-treated patients and at a greater frequency than placebo were: administration site pain, back pain, pain, diarrhea, dizziness, ligament sprain, contusion, influenza, oropharyngeal pain, rhinitis, skin abrasion, ear infection, seasonal allergy, tachycardia, catheter site related reaction, constipation, and fracture.

Known risk factors include the following: we may not be able to comply with all FDA post-approval commitments and requirements with respect to our products in a timely manner or at all; our dependence on certain manufacturers to produce our products and product candidates, including any inability on our part to accurately anticipate product demand and timely secure manufacturing capacity to meet product demand, may impair the availability of product to successfully support various programs; success in preclinical testing and early clinical trials, especially if based on a small patient sample, does not ensure that later clinical trials will be successful, and early results from a clinical trial do not necessarily predict final results; the expected benefits and opportunities related to our agreements with our strategic partners may not be realized or may take longer to realize than expected due to a variety of reasons, including any inability of the parties to perform their commitments and obligations under the agreements, challenges and uncertainties inherent in product research and development and manufacturing limitations; we may not be able to execute on our business plans, including meeting our expected or planned regulatory milestones and timelines, research and clinical development plans, and bringing our product candidates to market, for various reasons, some of which may be outside of our control, including possible limitations of company financial and other resources, manufacturing limitations that may not be anticipated or resolved for in a timely manner, the COVID-19 pandemic and regulatory, court or agency decisions, such as decisions by the United States Patent and Trademark Office with respect to patents that cover our product candidates; and those risks identified under the heading “Risk Factors” in our most recent Annual Report on Form 10-K for the year ended December 31, 2019 and most recent Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission (SEC) as well as other SEC filings made by the Company which you are encouraged to review.

Any of the foregoing risks could materially and adversely affect the Company’s business, results of operations and the trading price of Sarepta’s common stock. You should not place undue reliance on forward-looking statements. Sarepta does not undertake any obligation to publicly update its forward-looking statements based on events or circumstances after the date hereof, except to the extent required by applicable law or SEC rules.
