欢迎关注凯莱英药闻 2024年11月26日，Arrowhead Pharmaceuticals（“Arrowhead”）宣布与 Sarepta Therapeutics（“Sarepta”）达成全球许可和合作协议。该协议涵盖肌肉、中枢神经系统(CNS) 和肺部罕见遗传疾病的多个临床和临床前项目，数量多达13个。 根据协议条款，Arrowhead 将获得 8.25 亿美元，其中包括 5 亿美元现金和 3.25 亿美元股权投资，投资溢价达到了Arrowhead近30天成交量加权平均价格的35%；以及与当前临床项目相关的近3亿美元的短期里程碑付款。接下来的五年内，Sarepta还将通过每年支付5000万美元的方式再支付2.5亿美元。此外，该协议还包括约100亿美元的未来里程碑付款，相当于每个项目1.1亿至4.1亿美元的开发里程碑付款，以及5亿至7亿美元的销售里程碑付款。 截至9月30日，Sarepta拥有13.9亿美元的现金、现金等价物和短期投资。Sarepta方表示，公司将完全用现金支付这笔交易；此外，还将启动高达5亿美元的股票回购计划。    协议涉及的合作药物 本次协议共涉及四个临床项目和三个临床前项目；此外，Sarepta还有权增加多达六个发现阶段的项目。 临床阶段项目： ARO-DUX4：是首个利用Arrowhead专有靶向RNAi分子（TRiMTM）平台靶向骨骼肌中疾病相关基因的临床候选药物，正在开发用于1 型面肩肱型肌营养不良症患者。该药物旨在针对编码 DUX4 蛋白的基因，目前正在进行 1/2 期临床研究。 ARO-DM1：被设计为减少肌肉中肌强直性肌营养不良症蛋白激酶（DMPK）基因的表达，正在开发用于1 型肌强直性营养不良症（DM 1）患者。DM1的发病机制是由DMPK转录物3 '非翻译区中扩增的CUG三核苷酸重复序列驱动的，这些异常的转录物导致某些信使RNA的错误调节剪接。2024年3月，ARO-DM1已在一项Ⅰ/Ⅱa期的双盲、安慰剂对照、剂量递增研究中完成首批受试者用药。 ARO-MMP7：是一款靶向抑制基质金属蛋白酶7（MMP7）表达的siRNA药物，用于治疗特发性肺纤维化（IPF），目前正在进行1/2a期AROMMP7-1001研究，旨在评估ARO-MMP7在非嗜肝病毒(NHV)感染和IPF患者中的安全性、耐受性、药代动力学和药效学。 ARO-ATXN2：是一款靶向中枢神经系统中的共济失调蛋白2（ATXN2）的siRNA药物，通过内注射给予，直接作用于脊髓，以期最大限度降低ATXN2蛋白的水平，从根源上减少疾病的进展。目前正处于 1/2 期研究中。 临床前项目： RO-HTT：是一款靶向亨廷顿蛋白（HTT），正开发用于治疗亨廷顿病，预计 2025 年可进行 CTA。 ARO-ATXN1：是一款靶向共济失调蛋白1（ATXN1）的siRNA药物，正开发用于脊髓小脑共济失调 1 (SCA1) 患者，预计 2026 年可进行 CTA。 ARO-ATXN3：是一款靶向共济失调蛋白3（ATXN3）的siRNA药物，正开发3型小脑共济失调症（SCA3）患者，预计 2026 年可进行 CTA。 本次交易是Sarepta自创立以来最重要的研发投资。据知名分析师称，此次合作的框架与2021年12月罗氏和Recursion的交易类似，尽管管线规模较小。此前的交易中，罗氏旨在通过 Recursion操作系统（OS）利用技术赋能的药物发现，在神经科学的关键领域以及肿瘤适应症中更快速地确定新的靶点和先进药物；该合作可能启动多达40个项目，每个项目的开发、商业化、净销售额里程碑以及净销售额的分层版税将超过3亿美元，潜在交易总金额超120亿美元。         关于Sarepta Part.1 公司简介 Sarepta 是一家全球性的生物技术公司，专注于通过发现和开发独特的RNA靶向疗法、基因疗法和其他用于治疗罕见疾病的基因治疗模式来帮助患者。 Part.2 财务情况 2024 H1，公司总营收7.76亿美元，同比增长51%；净产品收入共计7.2亿美元，同比增长53%；研发费用3.8亿美元，同比下降22%。基于此，公司提供了2025年产品净收入29亿至31亿美元的指导目标。 公司四款获批疗法的产品净收入总额为7.2亿美元，其中Q2季度产品净收入总额为3.605亿美元，同比增长51%。 Part.3 管线情况 目前，公司管线包括40多个处于不同开发阶段的项目，适应症涵盖包括神经肌肉，中枢神经系统和心脏病学在内的多个治疗领域。 其中，公司已经开发并商业化了以下四款经批准用于治疗杜氏肌营养不良（DMD）的产品：Exondys 51（eteplirsen）、Vyondys 53（golodirsen）、Amondys 45（casimersen）和Elevidys。上述药物分别于2016年、2019年、2021年和2023年获FDA批准，分别用于外显子51、53和45跳跃的DMD患者和年龄在4-5岁之间患有DMD的非卧床儿童患者。 EXONDYS 51是最早获FDA批准的用于治疗DMD的产品，也是FDA批准上市的第一款DMD治疗产品。 Vyondys 53是一种磷酰二胺吗啉代寡聚核苷酸，通过靶向抗肌萎缩蛋白mRNA前体的剪接过程，引入外显子53跳跃，旨在产出截短但仍具有功能的抗肌萎缩蛋白。 AMONDYS 45通过一种称为外显子跳跃的基因疗法进行治疗，该疗法针对 DMD基因中的特定突变，以恢复功能性肌营养不良蛋白的产生。该药物适用于已确认DMD基因突变的患者，该突变可修正外显子45跳跃，从而产生缩短但有功能的肌营养不良蛋白；能够减缓疾病的进展并改善患者的生活质量。 Elevidys（SRP-9001）是公司与罗氏共同开发的一款基于腺相关病毒（AAV）载体的基因疗法，通过基因工程办法将编码微抗肌萎缩蛋白的靶基因递送到骨骼和心肌肌肉组织，以弥补抗肌萎缩蛋白缺失。该药物最早于2023年6月获批用于治疗4-5岁DMD儿童患者。2024年6月，FDA已批准扩大ELEVIDYS的适应症，包括4岁及以上的具有确认基因突变的DMD患者。FDA为可行走的患者授予了常规批准，并为不可行走的患者授予了加速批准，意味着该疗法将可应用于更广泛的DMD患者人群。 此外，公司重点产品SRP-9003是一款在研基因疗法，用于治疗2E型肢带型肌营养不良症（LGMD2E，即β-肌聚糖病）。  Arrowhead的相关交易 除本次达成交易外，Arrowhead于近年来先后达成多笔合作。 参考资料 1、各公司官网 2、大药时纪、新药猎人笔记、医药魔方、细胞基因治疗前沿、药融圈 感谢关注、转发，转载授权、加行业交流群，请加管理员微信号“hxsjjf1618”。 “在看”点一下

CAMBRIDGE, Mass.--( BUSINESS WIRE )--Sarepta Therapeutics, Inc. (NASDAQ:SRPT), the leader in precision genetic medicine for rare diseases, today reported financial results for the third quarter 2024. “ I am pleased to report another strong quarter of performance, as we posted $429.8 million in net product revenue for the third quarter, a 39% increase over the same quarter of the prior year. Reflecting our detailed preparation and track record of commercial execution, the launch of ELEVIDYS is proceeding to plan. ELEVIDYS net product revenue was $181.0 million in the quarter, exceeding prior guidance. If one includes royalty revenue generated on Roche’s ex-US sales of ELEVIDYS, total ELEVIDYS performance was $190.5 million for the quarter. Likewise, net product revenue for our three PMOs -- EXONDYS 51, VYONDYS 53, and AMONDYS 45 – performed well, achieving approximately $248.8 million in the quarter and, as anticipated, reflecting a lack of near-term cannibalization from the launch of ELEVIDYS,” said Doug Ingram, president and chief executive officer, Sarepta Therapeutics. “ At the same time, we have made important decisions regarding portfolio prioritization and have made great progress on our pipeline in the quarter. As examples, by mid-2025 we will have submitted a Biologics License Application for one and will be in clinical trials for two others of our Limb-girdle muscular dystrophy programs. Assuming success, these three therapeutic candidates will deliver our next wave of approved therapies as our multi-program platform advances productively.” Third Quarter 2024 and Recent Developments: Sarepta has made the decision to discontinue the SRP-5051 (vesleteplirsen) development program. This decision was informed by information available to date, including the risk-benefit of the program, feedback from the FDA, and the evolving therapeutic landscape for Duchenne. Presented new data from its neuromuscular portfolio at 2024 World Muscle Society Congress (WMS 2024): Among the multiple presentations from Sarepta at WMS 2024 were new safety and efficacy results from several studies in the SRP-9001 clinical development program. These data included: Skeletal muscle MRI data from Study 9001-301 EMBARK where multiple muscles from a subset of patients (n=39) were evaluated using MRI/MRS and MRI T2 signal prior to treatment and at 52 weeks post treatment. Across all measures, patients treated with SRP-9001 showed improvement over the placebo group with less accumulation of fat and fibrosis. The finding correlates with the functional outcomes in Part 1 of EMBARK which showed stabilization or slowing of disease progression in patients treated with SRP-9001 compared to placebo. Cardiac MRI data from EMBARK where an assessment of a subgroup of patients (n=19), found no negative effects on cardiac safety compared to placebo at 52 weeks and no differences in cardiac measures in SRP-9001-treated patients compared to the placebo group at one year. Sarepta plans for future longitudinal cardiac MRI studies to evaluate the long-term protection of cardiac muscle. Five-year functional results from Study SRP-9001-101, the longest-term data to date for a gene therapy in Duchenne. These patients, with an average age of 10 years at the time of the assessment, were stable or showed a slowing of disease progression with an increase in divergence from natural history over time as shown by an external control analysis. Notably this evaluation was conducted at an age when many Duchenne patients are entering the steep decline phase of the disease. The five-year results showed: A 9.8 point (p=0.0127) increase in change from baseline in the North Star Ambulatory Assessment (NSAA) total score to five years. At year five the sustained increase in NSAA total score was statistically significant and clinically meaningful when compared to an external control cohort. An 8.8 second decrease (p=0.0198) in time to rise from floor, change from baseline to five years. The improvement was statistically significant and clinically meaningful when compared to an external control cohort. Patients maintained their 10-meter walk test time throughout the five years. No new safety signals. Results from EMBARK study of delandistrogene moxeparvovec published in Nature Medicine : In early October, efficacy and safety results from Part 1 of the EMBARK study of delandistrogene moxeparvovec-rokl for the treatment of Duchenne muscular dystrophy were published in Nature Medicine . These published results demonstrate a treatment benefit with delandistrogene moxeparvovec that is clinically meaningful and similar regardless of age and a favorable risk-benefit profile. EMBARK, also known as Study SRP-9001-301, is a global, randomized, double-blind, placebo-controlled, Phase 3 clinical study of delandistrogene moxeparvovec in patients with Duchenne muscular dystrophy between the ages of 4 through 7 years.

As of September 30, 2024 As of December 31, 2023 (in millions) Cash, cash equivalents, restricted cash and investments $ 1,395.8 $ 1,691.8 Revenues Total revenues increased by $135.4 million for the three months ended September 30, 2024, compared to the same period of 2023. The increase primarily reflects the initial product launch of ELEVIDYS in June 2023 and expanded label in June 2024, partially offset by a $22.5 million decrease in the amortization of the single, combined performance obligation under our collaboration agreement with F. Hoffman-La Roche Ltd. (“Roche”), which was fully amortized as of December 31, 2023. Total revenues increased by $397.0 million for the nine months ended September 30, 2024, compared to the same period of 2023. The increase primarily reflects the initial product launch of ELEVIDYS in June 2023 and expanded label in June 2024, as well as the $48.0 million of collaboration revenue recognized related to an option declined by Roche to acquire the ex-US rights to a certain external, early stage Duchenne-specific program, partially offset by a $66.8 million decrease in the amortization of the single, combined performance obligation under our collaboration agreement with Roche, which was fully amortized as of December 31, 2023. Additionally, included in total revenues for the three and nine months ended September 30, 2024, is $37.4 million and $45.8 million, respectively, of contract manufacturing and other revenues associated with commercial ELEVIDYS supply delivered to Roche and royalty revenue received from Roche, with no similar activity for the same periods of 2023. Cost of sales (excluding amortization of in-licensed rights) Cost of sales (excluding amortization of in-license rights) increased by $54.7 million and $80.6 million for the three and nine months ended September 30, 2024, respectively, compared with the same periods of 2023. The increases in both periods primarily reflect the initial product launch of ELEVIDYS in June 2023 and expanded label in June 2024. For the three and nine months ended September 30, 2024, we recognized $13.7 million and $15.4 million of cost of sales related to products sold to Roche under our collaboration agreement, with no similar activity for the same periods of 2023. Operating expenses and others Research and development expenses increased by $30.2 million for the three months ended September 30, 2024, compared with the same period of 2023. The increase in research and development expense primarily reflects $55.4 million of costs associated with the termination of the development, commercial manufacturing and supply agreement (the “Thermo Agreement”) related to Brammer Bio MA, LLC, an affiliate of Thermo Fisher Scientific, Inc. in August 2024, net of the reimbursable termination costs by Roche, partially offset by a decrease in clinical and manufacturing activity for our PPMO platform and Eteplirsen program. Research and development expenses decreased by $77.3 million for the nine months ended September 30, 2024, compared with the same period of 2023. The decrease in research and development expense primarily reflects capitalization of commercial batches of ELEVIDYS manufactured after its approval in June 2023, partially offset by $55.4 million of costs associated with the termination of the Thermo Agreement, net of the reimbursable termination costs by Roche. Non-GAAP research and development expenses increased by $35.9 million for the three months ended September 30, 2024, compared with the same period of 2023. Non-GAAP research and development expenses decreased by $65.0 million for the nine months ended September 30, 2024, compared with the same period of 2023. Selling, general and administrative expenses increased by $7.3 million and $43.8 million for the three and nine months ended September 30, 2024, compared with the same periods of 2023. The increase in selling, general and administrative expenses for both periods is primarily driven by professional services used to support the continued efforts to commercialize ELEVIDYS and ongoing litigation matters, the timing of charitable contributions, compensation due to changes in headcount, as well as the achievement of performance conditions related to certain Performance Stock Units. Non-GAAP selling, general and administrative expenses increased by $7.4 million and $40.3 million for the three and nine months ended September 30, 2024, respectively, compared with the same periods of 2023. For the three months ended September 30, 2024, other income (loss), net increased by $24.1 million, compared with the same period of 2023, which primarily reflects an impairment of a strategic investment during the three months ended September 30, 2023, with no similar activity in 2024. For the nine months ended September 30, 2024, other income (loss), net increased by $300.6 million compared with the same period of 2023, which primarily reflects a $387.3 million loss on debt extinguishment offset by a $102.0 million gain on the sale of a Priority Review Voucher (“PRV”) during the nine months ended September 30, 2023, with no similar activities in 2024. Income tax expense for the three months ended September 30, 2024 and 2023, was approximately $0.4 million and $7.8 million, respectively. Income tax expense for the nine months ended September 30, 2024 and 2023, was approximately $12.8 million and $21.2 million, respectively. Income tax expense for all periods presented primarily relates to state, federal and foreign income taxes for which available tax losses or credits were not available to offset. Use of Non-GAAP Measures In addition to the GAAP financial measures set forth in this press release, we have included the following non-GAAP measurements: Non-GAAP income (loss) is defined by us as GAAP net income (loss) excluding interest income, net, depreciation and amortization expense, stock-based compensation expense, the estimated income tax impact of each pre-tax non-GAAP adjustment and other items. Non-GAAP earnings (loss) per share is defined by us as non-GAAP net income (loss), as defined previously, divided by the weighted-average number of shares of common stock and dilutive common stock equivalents outstanding. The non-GAAP earnings per share is calculated using diluted shares whereas the non-GAAP net loss per share is calculated using basic shares as all other instruments are anti-dilutive. Non-GAAP operating income (loss) is defined by us as GAAP operating income (loss) excluding depreciation and amortization expense, stock-based compensation expense and other items. Non-GAAP research and development expenses are defined by us 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 us as GAAP selling, general and administrative expenses excluding depreciation expense, stock-based compensation expense and other items. The following components are used to adjust our GAAP financial measures into the previously defined non-GAAP measurements: Interest, depreciation and amortization - Interest income, net 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 our operations. 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 our operating performance. Amortization expense primarily associated with patent costs are amortized over a period of several years after acquisition or patent application or renewal. Stock-based compensation expenses - Stock-based compensation expenses represent non-cash charges related to equity awards we have granted. Although these are recurring charges to operations, we believe 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 our control. Therefore, we believe that excluding these charges facilitates comparisons of our operational performance in different periods. Other items - We evaluate other items of expense and income on an individual basis. We take into consideration quantitative and qualitative characteristics of each item, including (a) nature, (b) whether the items relate to our ongoing business operations, and (c) whether we expect the items to continue or occur on a regular basis. These other items include impairment of strategic investments, change in fair value of derivatives, gain from sale of the PRV and loss on debt extinguishment and may include other items that fit the above characteristics in the future. We exclude from our non-GAAP results: The impairment of any strategic investments as it is a non-cash item and is not considered to be a normal operating expense due to the variability of amount and lack of predictability as to the occurrence and/or timing of such impairments. The loss on debt extinguishment, which is considered to be an infrequent and non-cash event as it is associated with a distinct financing decision and is not indicative of the performance of our core operations, which accordingly, would make it difficult to compare our results to peer companies that also provide non-GAAP disclosures. The gain from sale of the PRV obtained as a result of the FDA accelerated approval of ELEVIDYS in June 2023 as it is a non-recurring event. The change in fair value of derivatives related to 1.) regulatory-related contingent payments meeting the definition of a derivative to Myonexus selling shareholders as well as to an academic institution under a separate license agreement and 2.) the derivative asset associated with capped call options for our $570.0 million aggregate principal amount of senior convertible notes due on November 15, 2024, as these are non-cash items and are not considered to be normal operating expenses due to the variability of amounts and lack of predictability as to occurrence and/or timing. Beginning in the fourth quarter of 2023, amortization of in-licensed rights (formerly included within depreciation and amortization expense) and income tax (benefit) expense are no longer excluded from the non-GAAP results. We now include the income tax effect of adjustments, which represents the estimated income tax impact of each pre-tax non-GAAP adjustment based on the applicable effective income tax rate. Non-GAAP financial results for the for the three and nine months ended September 30, 2023 have been updated to reflect this change for comparability. We use these non-GAAP measures as key performance measures for the purpose of evaluating operational performance and cash requirements internally. We also believe these non-GAAP measures increase comparability of period-to-period results and are useful to investors as they provide a similar basis for evaluating our performance as is applied by management. These non-GAAP measures are not intended to be considered in isolation or to replace the presentation of our 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 operating income (loss), non-GAAP net income (loss), and non-GAAP diluted net earnings (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 exclusion, or “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 (DMD) 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 in skeletal muscle observed in some patients treated with EXONDYS 51. Continued approval for this indication 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 bronchospasm, chest pain, cough, tachycardia, and urticaria 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. The most common adverse reactions from observational clinical studies (N=163) seen in greater than 10% of patients were headache, cough, rash, and vomiting. Other adverse events may occur. To report SUSPECTED ADVERSE REACTIONS, contact Sarepta Therapeutics, Inc. at 1-888-SAREPTA (1-888-727-3782) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . For further information, please see the full Prescribing Information . About VYONDYS 53 VYONDYS 53 (golodirsen) 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 (DMD) 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 for this indication 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 CONTRAINDICATIONS: VYONDYS 53 is contraindicated in patients with a serious hypersensitivity reaction to golodirsen or to any of the inactive ingredients in VYONDYS 53. Anaphylaxis has occurred in patients receiving VYONDYS 53. WARNINGS AND PRECAUTIONS Hypersensitivity Reactions : Hypersensitivity reactions, including anaphylaxis, 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, interrupting, or discontinuing the VYONDYS 53 therapy and monitor until the condition resolves. VYONDYS 53 is contraindicated in patients with a history of a serious hypersensitivity reaction to golodirsen or to any of the inactive ingredients in VYONDYS 53. Kidney Toxicity: Kidney toxicity was observed in animals who received golodirsen. Although kidney toxicity was not observed in the clinical studies with VYONDYS 53, the clinical experience with VYONDYS 53 is limited, and kidney toxicity, including potentially fatal glomerulonephritis, has been observed after administration of some antisense oligonucleotides. Kidney 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 kidney function in DMD patients. Serum cystatin C, urine dipstick, and urine protein- to-creatinine ratio should be measured before starting VYONDYS 53. Consider also measuring glomerular filtration rate using an exogenous filtration marker before starting VYONDYS 53. During treatment, monitor urine dipstick every month, and serum cystatin C and urine protein-to- creatinine ratio every three months. Only urine expected to be free of excreted VYONDYS 53 should be used for monitoring of urine protein. Urine obtained on the day of VYONDYS 53 infusion prior to the infusion, or urine obtained at least 48 hours after the most recent infusion, may be used. Alternatively, use a laboratory test that does not use the reagent pyrogallol red, as this reagent has the potential to cross react with any VYONDYS 53 that is excreted in the urine and thus lead to a false positive result for urine protein. If a persistent increase in serum cystatin C or proteinuria is detected, refer to a pediatric nephrologist for further evaluation. ADVERSE REACTIONS: 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. Other adverse events may occur. To report SUSPECTED ADVERSE REACTIONS, contact Sarepta Therapeutics, Inc. at 1-888-SAREPTA (1-888-727-3782) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . For further information, please see the full Prescribing Information . About AMONDYS 45 AMONDYS 45 (casimersen) uses Sarepta’s proprietary phosphorodiamidate morpholino oligomer (PMO) chemistry and exon-skipping technology to bind to exon 45 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 45 skipping. Exon skipping is intended to allow for production of an internally truncated dystrophin protein. AMONDYS 45 is indicated for the treatment of Duchenne muscular dystrophy (DMD) in patients who have a confirmed mutation of the DMD gene that is amenable to exon 45 skipping. This indication is approved under accelerated approval based on an increase in dystrophin production in skeletal muscle observed in patients treated with AMONDYS 45. Continued approval for this indication may be contingent upon verification of a clinical benefit in confirmatory trials. AMONDYS 45 has met the full statutory standards for safety and effectiveness and as such is not considered investigational or experimental. Important Safety Information for AMONDYS 45 CONTRAINDICATIONS : AMONDYS 45 is contraindicated in patients with a known serious hypersensitivity to casimersen or any of the inactive ingredients in AMONDYS 45. Instances of hypersensitivity including angioedema and anaphylaxis have occurred. WARNINGS AND PRECAUTIONS Hypersensitivity: Hypersensitivity reactions, including angioedema and anaphylaxis, have occurred in patients who were treated with AMONDYS 45. If a hypersensitivity reaction occurs, institute appropriate medical treatment, and consider slowing the infusion, interrupting, or discontinuing the AMONDYS 45 infusion and monitor until the condition resolves. AMONDYS 45 is contraindicated in patients with known serious hypersensitivity to casimersen or to any of the inactive ingredients in AMONDYS 45. Kidney Toxicity : Kidney toxicity was observed in animals who received casimersen. Although kidney toxicity was not observed in the clinical studies with AMONDYS 45, kidney toxicity, including potentially fatal glomerulonephritis, has been observed after administration of some antisense oligonucleotides. Kidney function should be monitored in patients taking AMONDYS 45. Because of the effect of reduced skeletal muscle mass on creatinine measurements, creatinine may not be a reliable measure of kidney function in DMD patients. Serum cystatin C, urine dipstick, and urine protein-to-creatinine ratio should be measured before starting AMONDYS 45. Consider also measuring glomerular filtration rate using an exogenous filtration marker before starting AMONDYS 45. During treatment, monitor urine dipstick every month, and serum cystatin C and urine protein-to-creatinine ratio (UPCR) every three months. Only urine expected to be free of excreted AMONDYS 45 should be used for monitoring of urine protein. Urine obtained on the day of AMONDYS 45 infusion prior to the infusion, or urine obtained at least 48 hours after the most recent infusion, may be used. Alternatively, use a laboratory test that does not use the reagent pyrogallol red, as this reagent has the potential to cross react with any AMONDYS 45 that is excreted in the urine and thus lead to a false positive result for urine protein. If a persistent increase in serum cystatin C or proteinuria is detected, refer to a pediatric nephrologist for further evaluation. Adverse Reactions: Adverse reactions occurring in at least 20% of patients treated with AMONDYS 45 and at least 5% more frequently than in the placebo group were (AMONDYS 45, placebo): upper respiratory infections (65%, 55%), cough (33%, 26%), pyrexia (33%, 23%), headache (32%, 19%), arthralgia (21%, 10%), and oropharyngeal pain (21%, 7%). Other adverse reactions that occurred in at least 10% of patients treated with AMONDYS 45 and at least 5% more frequently than in the placebo group were: ear pain, nausea, ear infection, post-traumatic pain, and dizziness and light-headedness. Other adverse events may occur. To report SUSPECTED ADVERSE REACTIONS, contact Sarepta Therapeutics, Inc. at 1-888-SAREPTA (1-888-727-3782) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .

About ELEVIDYS (delandistrogene moxeparvovec-rokl) ELEVIDYS (delandistrogene moxeparvovec-rokl) is a single-dose, adeno-associated virus (AAV)-based gene transfer therapy for intravenous infusion designed to address the underlying genetic cause of Duchenne muscular dystrophy – mutations or changes in the DMD gene that result in the lack of dystrophin protein – through the delivery of a transgene that codes for the targeted production of ELEVIDYS micro-dystrophin in skeletal muscle. ELEVIDYS is indicated for the treatment of Duchenne muscular dystrophy (DMD) in individuals at least 4 years of age. For patients who are ambulatory and have a confirmed mutation in the DMD gene For patients who are non-ambulatory and have a confirmed mutation in the DMD gene. The DMD indication in non-ambulatory patients is approved under accelerated approval based on expression of ELEVIDYS micro-dystrophin (noted hereafter as “micro-dystrophin”) in skeletal muscle. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). IMPORTANT SAFETY INFORMATION CONTRAINDICATION: ELEVIDYS is contraindicated in patients with any deletion in exon 8 and/or exon 9 in the DMD gene. WARNINGS AND PRECAUTIONS: Infusion-related Reactions: Infusion-related reactions, including hypersensitivity reactions and anaphylaxis, have occurred during or up to several hours following ELEVIDYS administration. Closely monitor patients during administration and for at least 3 hours after the end of infusion. If symptoms of infusion-related reactions occur, slow, or stop the infusion and give appropriate treatment. Once symptoms resolve, the infusion may be restarted at a lower rate. ELEVIDYS should be administered in a setting where treatment for infusion-related reactions is immediately available. Discontinue infusion for anaphylaxis. Acute Serious Liver Injury: Acute serious liver injury has been observed with ELEVIDYS, and administration may result in elevations of liver enzymes (such as GGT, GLDH, ALT, AST) or total bilirubin, typically seen within 8 weeks. Patients with preexisting liver impairment, chronic hepatic condition, or acute liver disease (e.g., acute hepatic viral infection) may be at higher risk of acute serious liver injury. Postpone ELEVIDYS administration in patients with acute liver disease until resolved or controlled. Prior to ELEVIDYS administration, perform liver enzyme test and monitor liver function (clinical exam, GGT, and total bilirubin) weekly for the first 3 months following ELEVIDYS infusion. Continue monitoring if clinically indicated, until results are unremarkable (normal clinical exam, GGT, and total bilirubin levels return to near baseline levels). Systemic corticosteroid treatment is recommended for patients before and after ELEVIDYS infusion. Adjust corticosteroid regimen when indicated. If acute serious liver injury is suspected, consultation with a specialist is recommended. Immune-mediated Myositis: In clinical trials, immune-mediated myositis has been observed approximately 1 month following ELEVIDYS infusion in patients with deletion mutations involving exon 8 and/or exon 9 in the DMD gene. Symptoms of severe muscle weakness, including dysphagia, dyspnea, and hypophonia, were observed. Limited data are available for ELEVIDYS treatment in patients with mutations in the DMD gene in exons 1 to 17 and/or exons 59 to 71. Patients with deletions in these regions may be at risk for a severe immune-mediated myositis reaction. Advise patients to contact a physician immediately if they experience any unexplained increased muscle pain, tenderness, or weakness, including dysphagia, dyspnea, or hypophonia, as these may be symptoms of myositis. Consider additional immunomodulatory treatment (immunosuppressants [e.g., calcineurin-inhibitor] in addition to corticosteroids) based on patient’s clinical presentation and medical history if these symptoms occur. Myocarditis : Acute serious myocarditis and troponin-I elevations have been observed following ELEVIDYS infusion in clinical trials. If a patient experiences myocarditis, those with pre-existing left ventricle ejection fraction (LVEF) impairment may be at higher risk of adverse outcomes. Monitor troponin-I before ELEVIDYS infusion and weekly for the first month following infusion and continue monitoring if clinically indicated. More frequent monitoring may be warranted in the presence of cardiac symptoms, such as chest pain or shortness of breath. Advise patients to contact a physician immediately if they experience cardiac symptoms. Preexisting Immunity against AAVrh74: In AAV-vector based gene therapies, preexisting anti-AAV antibodies may impede transgene expression at desired therapeutic levels. Following treatment with ELEVIDYS, all patients developed anti-AAVrh74 antibodies. Perform baseline testing for presence of anti-AAVrh74 total binding antibodies prior to ELEVIDYS administration. ELEVIDYS administration is not recommended in patients with elevated anti-AAVrh74 total binding antibody titers greater than or equal to 1:400. Adverse Reactions: The most common adverse reactions (incidence ≥5%) reported in clinical studies were vomiting, nausea, liver injury, pyrexia, and thrombocytopenia.
