Real-world phosphorodiamidate morpholino oligomer treatment patterns in Duchenne muscular dystrophy: a claims-based analysis.

Article

作者: Veerapandiyan, Aravindhan ; Ung, Brian ; Signorovitch, James ; Nadkar, Aalok ; DeYoung, Kathryn ; Grabich, Shannon

Aim: Phosphorodiamidate morpholino oligomers (PMOs) are exon-skipping therapies administered through once-weekly intravenous infusions used to treat Duchenne muscular dystrophy (DMD). This study assessed treatment patterns among patients with DMD receiving PMOs using administrative claims data while accounting for limitations in claims data for these therapies. Materials & methods: This study used Inovalon^® public and private closed claims data (1 June 2016-31 March 2024). Male patients with ≥1 claim for a PMO approved for DMD in the US (eteplirsen, casimersen, golodirsen and viltolarsen) were included. Index date was the first PMO claim. All available follow-up data were used to assess continuous PMO claims coverage, ≥60-day and ≥30-day gaps in PMO claims and PMO re-initiation after a gap. Adherence during 1 year after index was measured using proportion of days covered (PDC). Treatment patterns were also assessed in patients stratified by baseline algorithm-defined nonambulatory status (inferred from claims). Results: Among 397 patients included, median (IQR) follow-up time was 788 (484, 1109) days. Gaps in PMO claims coverage occurred in 190 (47.9%) and 254 (64.0%) patients using ≥60-day and ≥30-day gaps, respectively, among whom 110 (57.9%) and 176 (69.3%) had PMO re-initiation. Using ≥60-day and ≥30-day gap lengths, median (IQR) time to first gap in PMO claims was 25.5 (22.3, 32.9) months and 13.5 (10.2, 17.7) months, respectively and median (IQR) time to PMO re-initiation (not including gap time) was 4.4 (2.8, 8.7) months and 2.5 (1.7, 3.2) months. Median (IQR) PDC was 78.8% (38.8, 94.0) during 1 year after index. PMO treatment patterns were generally similar in patients stratified by algorithm-defined nonambulatory status. Conclusion: In an analysis of administrative claims data, adherence to PMO treatment for DMD was high. For patients with a gap in PMO claims, most subsequently re-initiated treatment, indicating lower discontinuation rates than previously reported.

Clinical applications of exon-skipping antisense oligonucleotides in neuromuscular diseases

Review

作者: Muntoni, Francesco ; Zhou, Haiyan ; Aguti, Sara ; Torres-Masjoan, Laia

Four exon-skipping antisense oligonucleotides (ASOs) have been approved by the US Food and Drug Administration (FDA) for the treatment of Duchenne muscular dystrophy (DMD), including eteplirsen, golodirsen, viltolarsen, and casimersen. Current data from long-term real-world usage of these ASOs suggests a broad safety profile and a delay in muscle deterioration. Nevertheless, the exon-skipping efficacy and dystrophin protein production of these ASOs are limited, suggesting the need for more efficient ASOs. Over the past decade, many studies have focused on improving ASO efficacy by incorporating novel chemical modifications or bioconjugations of a variety of moieties including peptides or antibodies to increase their cellular uptake by muscle cells, their endosomal escape, and their nuclear import to boost therapeutic efficacy. Many of these newly developed exon-skipping ASOs have been studied in clinical trials in DMD patients, and early findings suggest clear improvements in molecular efficacy compared to the earlier version of ASOs, although the safety track record may not be the same as the first-generation compounds. Here, we summarize the recent preclinical and clinical developments of ASOs and discuss the future challenges of exon-skipping therapies for DMD and other neuromuscular diseases.

Article

BACKGROUND:

Duchenne muscular dystrophy (DMD) is a hereditary neuromuscular disorder characterized by severe, progressive muscle wasting. Viltolarsen, a formulation consisting of exon 53-skipping antisense oligonucleotides of the dystrophin gene, has been indicated for some patients with DMD. However, reports describing the efficacy and safety of viltolarsen treatment in patients with DMD, particularly those comparing patients receiving viltolarsen with age- and time-period-matched controls, are limited. This study aimed to confirm the safety and efficacy of viltolarsen treatment in patients with DMD.

METHODS:

We retrospectively reviewed real-world data of patients with DMD aged 6-19 years who started viltolarsen treatment between July 2020 and February 2021 and compared them with age- and time-period-matched patients with DMD who did not receive viltolarsen.

RESULTS:

Five patients received viltolarsen treatment for over 3 years. Three of the four patients who received viltolarsen once weekly maintained motor function, while one ambulatory patient showed remarkably slow motor function decline. Conversely, eight of nine patients who did not receive viltolarsen and one patient who underwent intermittent viltolarsen treatment showed motor function deterioration. Two patients showed significant treatment-related adverse events, namely swelling of the dorsal surface of the right hand due to extravasation of viltolarsen in one patient and axillary lymph node enlargement due to frequent intravenous infusion in another patient. None of the patients discontinued viltolarsen.

CONCLUSIONS:

Viltolarsen was a safe and effective treatment for patients with DMD, and the findings highlighted the importance of once-weekly and uninterrupted viltolarsen treatment. The distinct safety and efficacy of viltolarsen require further investigation using a large number of cases and a long follow-up period.

Phase III Clinical Study with Therapeutic Drug for Duchenne Muscular Dystrophy (TAS-205) in Japan Did Not Meet Its Primary Endpoint

July 8, 2025 I Taiho Pharmaceutical Co., Ltd. announced that the results of a phase III, randomized, placebo-controlled, double-blind and open-label, extension study of TAS-205 in patients with Duchenne muscular dystrophy (DMD) (REACH-DMD) showed no significant difference in the mean change from baseline to 52 weeks in the time to rise from the floor, which was the primary endpoint in the ambulatory cohort of the study. The ambulatory cohort of this study was conducted in Japan as a placebo-controlled, multi-center, double-blind comparative study in male DMD patients aged 5 years and older. The purpose of this study is to evaluate the efficacy of TAS-205 by orally administering TAS-205 or a placebo twice daily for 52 weeks. A total of 82 patients were enrolled in 26 sites from November 2020 to December 2023. Detailed results from this study will be presented at an appropriate upcoming academic conference. For more information on this study (NCT04587908/jRCT2041200055), please visit: www.clinicaltrials.gov/ / https://jrct.mhlw.go.jp/en-top In December 2019, development of TAS-205 was selected as one of the 4th Cyclic Innovation for Clinical Empowerment (CiCLE*) program for fiscal 2019, under the application title: Development of an innovative therapeutic drug for DMD with a novel mechanism of action originating from Japan by utilizing patient registry. This program is operated by the Japan Agency for Medical Research and Development (AMED). *CiCLE：Cyclic Innovation for Clinical Empowerment About TAS-205 TAS-205 (INN: pizuglanstat) is a selective hematopoietic prostaglandin D synthase (HPGDS*) inhibitor discovered by Taiho Pharmaceutical. It is under development as a DMD treatment which can be used regardless of the dystrophin gene mutation type, controlling the decline in motor function in DMD patients by inhibiting HPGDS, which exacerbates the inflammatory response in DMD patients’ muscles. *HPGDS：Hematopoietic prostaglandin D synthase About CiCLE This program aims at creating a foundation (including human resources) for a radical transformation in the way research and development is conducted in response to needs arising in clinical settings and for accelerating the practical application to pharmaceutical products. It also seeks to drive the creation of an environment that strongly promotes the fostering of open innovation in the field of medical research and development through the combined efforts of government, academia, and the private sector. About DMD (Duchenne muscular dystrophy) DMD is a genetic disorder with a higher prevalence in young males. It is caused by a genetic mutation in a gene, which codes dystrophin protein supporting the framework of muscle cells. It is a refractory, serious illness leading to a loss of muscle strength caused by the inability to produce normal dystrophin protein. The prevalence of DMD is 1.9 to 3.4 per 100,000 individuals 1 , and there are an estimated 3,000 to 4,000 patients in Japan. Currently, oral steroids and viltolarsen are approved and delandistrogene moxeparvovec has received conditional and time-limited approval for DMD in Japan, however new treatment options are being awaited.

全球小核酸药物的上市及临床研究现状分析

点击上方的行舟Drug ▲ 添加关注全球小核酸药物的上市及临床研究现状分析来源《中国新药杂志》 2025年第34卷第12期作者杜慧，肖宇锋，张玢中国医学科学院/北京协和医学院医学信息研究所/图书馆摘要目的: 本研究旨在分析总结全球小核酸药物的上市及临床研究现状，探索其未来发展方向。方法: 利用药物早期研发情报数据库检索上市及临床在研的小核酸药物并对这些药物的分类、研发国家及机构、靶点、适应证和递送系统等信息进行详细分析。结果: 截至2024年9月18日，全球共有17个小核酸药物获批上市、192个小核酸药物处于临床研究状态，其中反义寡核苷酸药物和小干扰RNA药物数量较多。大多数临床在研的小核酸药物仍处于早期研发阶段，适应证已逐渐从早期的遗传病拓展到肿瘤、心血管疾病等慢性病领域，其中N-乙酰半乳糖胺偶联物是应用最广泛的递送系统。我国小核酸药物发展态势良好，企业管线布局以乙型肝炎和慢性病为主。结论: 小核酸药物已成为继小分子药物、抗体药物后的第三大类药物，其研发潜力巨大，市场前景广阔。未来的发展方向包括探索新的治疗靶点、多学科合作开发肝外递送系统以及加强产学研的深度合作，共同助力推进临床转化。关键词小核酸药物; 反义寡核苷酸; 小干扰RNA; 临床研究_正文_小核酸药物是由十几个到几十个核苷酸串联组成的短链核酸，通过干扰或调控基因表达实现疾病治疗目的。与传统的小分子化学药和抗体类药物相比，小核酸药物具有研发周期短、研发成功率高、候选靶点丰富、适应证分布广泛和治疗精准化等优点。小核酸药物主要包括反义寡核苷酸(antisense oligonucleotide，ASO)、小干扰RNA(small interfering RNA，siRNA)、微小RNA(microRNA，miRNA)、小激活RNA(small activating RNA，saRNA)、向导RNA(small-guide RNA，sgRNA)、适配体(aptamer)以及抗体核酸偶联药物(antibody-oligonucleotide conjugates，AOCs)、多肽核酸偶联药物(peptide-oligonu cleotide conjugates，POCs)等[1]。ASO是一类化学合成的单链寡核苷酸分子，通常由13~30个核苷酸组成，ASO通过沃森-克里克(Watson-Crick)碱基配对原则与靶标序列形成双链结构，从而影响靶基因的表达[2]。RNA干扰(RNA interference，RNAi)是将外源或内源RNA导入细胞后与靶基因的信使RNA(messenger RNA，mRNA)结合，从而阻断靶基因mRNA的翻译，进而抑制靶基因表达的一种技术。基于RNAi的小核酸药物有siRNA和miRNA，其中siRNA是一类长度为20~25个核苷酸的双链RNA分子，miRNA是内源性生成的单链RNA分子，长度通常为21~23个核苷酸[3]。saRNA是一种双链RNA分子，能够在转录水平上激活基因表达，而sgRNA则是单链RNA分子，在CRISPR/Cas9系统中起到导航作用，引导Cas9核酸酶到特定的基因位点进行编辑。适配体是一类具有特定三级结构的单链短核苷酸分子，与其他小核酸药物不同，适配体不通过碱基配对，而是类似于抗体，依靠其三维结构特异性结合配体。此外，AOCs和POCs将小核酸药物与抗体或多肽结合，提高小核酸药物的靶向性和递送效率[4]。自20世纪90年代初以来，小核酸药物领域经历了多次重大突破。1993年，Ambros和Ruvkun在秀丽隐杆线虫中首次发现miRNA，揭示了其在转录后基因调控中的重要作用[5]。1998年，Mello和Fire进一步阐明了RNAi的机制，为小核酸药物的发展奠定了理论基础，并于2006年荣获诺贝尔生理学或医学奖[6]。2023年，Karikó和Weissman因在核苷碱基修饰方面的贡献获得诺贝尔生理学或医学奖，其发现极大推动了mRNA疫苗和疗法的发展[7]。2024年，诺贝尔生理学或医学奖再次授予Ambros和Ruvkun，以表彰其在miRNA发现及miRNA在转录后基因调控中的作用方面作出的开创性贡献[8]。这些重要科学发现推动了小核酸药物的发展，国内外各大制药企业纷纷通过自主研发或合作引进管线等方式布局[9]。本研究使用科睿唯安公司的药物早期研发情报数据库(Cortellis Drug Discovery Intelligence，CDDI)检索上市及临床在研的小核酸药物，分析其分类、研发国家及机构、靶点、适应证和递送系统等信息，总结小核酸药物研发现状，探索其未来发展方向。资料与方法1 数据来源以科睿唯安公司CDDI数据库为检索来源，利用CDDI数据库检索“药物和生物制剂(Drugs&Bi ologics)”，在“药物分类(Product Category)”字段，限定“Antisense Therapy和Oligonucleotides，siRNA，mi croRNA，aptamer，saRNA，sgRNA，AOC，POC”，在“最高研发状态(Highest Phase)”字段，限定“Launched，Pre-Registered，PhaseⅢ，PhaseⅡ/Ⅲ，PhaseⅡ，PhaseⅠ/Ⅱ，PhaseⅠ”，共检索到17个已上市的小核酸药物和192个研发活跃(12~18个月内有进展的小核酸管线，去掉暂停/停止/未报告进展/非积极的项目)并处于临床研究阶段的小核酸药物，检索时间为2024年9月18日。2 数据处理数据处理阶段，对每种药物进行详细的临床试验匹配。利用CDDI数据库，针对研究范围内的192个小核酸药物，逐一访问其“临床试验(Clinical&Studies)”模块，并通过查阅和对比，实现了药物与相应临床试验的精确关联。文章内容由凡默谷小编查阅文献选取，排版与编辑为原创。如转载，请尊重劳动成果，注明【来源：凡默谷公众号】。结果1 已上市药物情况截至2024年9月18日，全球共有17款小核酸药物获批上市，见表1。1998年，首款ASO药物福米韦生获美国FDA批准上市，用于治疗获得性免疫缺陷综合征患者并发的由巨细胞病毒(cytomegalov irus，CMV)引起的视网膜炎。随着高效抗逆转录病毒治疗(highly active antiretroviral therapy，HAART)的发展，CMV感染病例显著减少，导致福米韦生的市场需求和销售额大幅下滑，该药于2002年在欧洲退市[10]。TTＲ: 转甲状腺素蛋白， transthyretin;
