Dyne Therapeutics Receives European Medicines Agency (EMA) Orphan Drug Designation for DYNE-251 in Duchenne Muscular Dystrophy
- Recently presented data demonstrated sustained functional improvement with DYNE-251 treatment through 18 months - - Data from the fully enrolled DELIVER registrational expansion cohort is planned for late 2025 - WALTHAM, Mass., April 24, 2025 (GLOBE NEWSWIRE) -- Dyne Therapeutics, Inc. (Nasdaq: DYN), a clinical-stage company focused on advancing life-transforming therapeutics for people living with genetically driven neuromuscular diseases, today announced that the European Commission (EC) has granted orphan drug designation for DYNE-251 for the treatment of Duchenne muscular dystrophy (DMD). DYNE-251 is being evaluated in the Phase 1/2 DELIVER global clinical trial in individuals with DMD who are amenable to exon 51 skipping. Long-term clinical data from the ongoing DELIVER trial of DYNE-251 that demonstrated unprecedented and sustained functional improvement at the selected registrational dose were presented in March at the 2025 Muscular Dystrophy Association (MDA) Clinical & Scientific Conference. Functional assessments in the DELIVER trial include Stride Velocity 95th Centile (SV95C), an objective digital outcome that is accepted as a primary endpoint for DMD clinical trials in Europe. 'Our recent long-term DELIVER trial results demonstrated clinically relevant and sustained functional improvement through 18 months, including as assessed by SV95C, which may support a strong rationale for regulatory approval in Europe,' said Doug Kerr, MD, PhD, chief medical officer of Dyne. 'We are pleased that the EC has granted orphan drug designation to DYNE-251, reinforcing our belief that our next-generation exon 51 skipping investigational therapy for DMD may be able to bring clinically meaningful functional improvement to those living with this devastating disease. With full enrollment of the registrational expansion cohort in the DELIVER trial complete, we look forward to sharing data from this cohort in late 2025 and the potential to move forward with our first regulatory submissions in early 2026.' The EC grants orphan drug designation to drugs and biologics intended for the treatment, diagnosis or prevention of rare, life-threatening or chronically debilitating diseases or conditions that affect fewer than five in 10,000 people in the European Union (EU). Orphan designation provides companies with certain benefits, including reduced regulatory fees, clinical protocol assistance, research grants and the potential for up to 10 years of market exclusivity in the EU if approved. DYNE-251 was also granted U.S. Food and Drug Administration (FDA) orphan drug and rare pediatric disease designations in March 2023. Key Milestones for the DELIVER Trial Dyne continues to pursue expedited approval pathways globally for DYNE-251 in patients with DMD who are amenable to exon 51 skipping. Dyne has fully enrolled the registrational expansion cohort of 32 patients as part of the DELIVER trial. Data from this cohort are planned for late 2025. Dyne anticipates filing a Biologics License Application (BLA) submission for US accelerated approval in early 2026. About the DELIVER Trial DELIVER is a randomized, placebo-controlled, double-blind, Phase 1/2 clinical trial evaluating the safety, tolerability and efficacy of DYNE-251 in patients with Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping. The multiple ascending dose (MAD) portion of the study resulted in the selection of a registrational dose and regimen of 20 mg/kg every four weeks. A registrational expansion cohort to support potential regulatory submissions for expediated approvals, including accelerated approval in the U.S., is fully enrolled. The primary endpoint for this cohort is the change from baseline in dystrophin protein levels as measured by Western blot. For more information on the DELIVER trial, visit (NCT05524883) and (2023-510351-31-00). About DYNE-251 DYNE-251 is an investigational therapeutic being evaluated in the Phase 1/2 global DELIVER clinical trial for people living with DMD who are amenable to exon 51 skipping. DYNE-251 consists of a phosphorodiamidate morpholino oligomer (PMO) conjugated to a fragment antibody (Fab) that binds to the transferrin receptor 1 (TfR1), which is highly expressed on muscle. It is designed to enable targeted muscle tissue delivery and promote exon skipping in the nucleus, allowing muscle cells to create internally shortened, near full-length dystrophin protein, with the goal of stopping or reversing disease progression. DYNE-251 has been granted fast track, orphan drug and rare pediatric disease designations by the U.S. Food and Drug Administration for the treatment of DMD mutations amenable to exon 51 skipping. In addition to DYNE-251, Dyne is building a global DMD franchise and has preclinical programs targeting other exons, including 53, 45 and 44. About Duchenne Muscular Dystrophy (DMD) DMD is a rare disease caused by mutations in the gene that encodes for dystrophin, a protein critical for the normal function of muscle cells. These mutations, the majority of which are deletions, result in the lack of dystrophin protein and progressive loss of muscle function. DMD occurs primarily in males and affects an estimated 12,000 to 15,000 individuals in the U.S. and 25,000 in Europe. Loss of strength and function typically first appears in pre-school age boys and worsens as they age. As the disease progresses, the severity of damage to skeletal and cardiac muscle often results in patients experiencing total loss of ambulation by their early teenage years and includes worsening cardiac and respiratory symptoms and loss of upper body function by the later teens. There is no cure for DMD, and currently approved therapies provide limited benefit. About Dyne Therapeutics Dyne Therapeutics is discovering and advancing innovative life-transforming therapeutics for people living with genetically driven neuromuscular diseases. Leveraging the modularity of its FORCE™ platform, Dyne is developing targeted therapeutics that deliver to muscle and the central nervous system (CNS). Dyne has a broad pipeline for neuromuscular diseases, including clinical programs for myotonic dystrophy type 1 (DM1) and Duchenne muscular dystrophy (DMD), and preclinical programs for facioscapulohumeral muscular dystrophy (FSHD) and Pompe disease.

Dyne Therapeutics Announces New Long-Term Clinical Data from Phase 1/2 DELIVER Trial of DYNE-251 in Duchenne Muscular Dystrophy Demonstrating Unprecedented and Sustained Functional Improvement Through 18 Months
- Continued favorable safety profile for DYNE-251 - - DELIVER Registrational Expansion Cohort is fully enrolled; data from this cohort planned for late 2025 - - Potential for Biologics License Application submission for U.S. accelerated approval in early 2026 - WALTHAM, Mass., March 16, 2025 (GLOBE NEWSWIRE) -- Dyne Therapeutics, Inc. (Nasdaq: DYN), a clinical-stage company focused on advancing life-transforming therapeutics for people living with genetically driven neuromuscular diseases, today announced new long-term clinical data from its ongoing Phase 1/2 DELIVER trial of DYNE-251 demonstrating unprecedented and sustained functional improvement at the selected registrational dose of 20 mg/kg Q4W (approximate PMO dose). The DELIVER trial is evaluating DYNE-251 in individuals with Duchenne muscular dystrophy (DMD) who are amenable to exon 51 skipping, and updated results from the trial are being presented this week at the 2025 Muscular Dystrophy Association (MDA) Clinical & Scientific Conference. 'With Dyne-251, we have the opportunity to deliver a durable and redosable therapy demonstrating clinically meaningful and sustained functional improvement in DMD. The consistency of these new data across multiple endpoints and timepoints underscores the potential of DYNE-251 to meaningfully address the significant unmet need in Duchenne despite available therapies,' said John Cox, president and chief executive officer of Dyne. 'We are rapidly advancing DYNE-251 toward a readout later this year with the potential to submit for U.S. accelerated approval in early 2026 based on a well-established regulatory pathway leveraging dystrophin expression as a surrogate endpoint. If approved, we believe there is an opportunity for rapid adoption by physicians and currently treated patients, as well as those naïve to therapy.' 'I am very encouraged by these new, long-term data for DYNE-251 in the exon 51 skip amenable population and the promise of sustained functional improvement which has continued to elude the DMD community,' said Pat Furlong, founder and president of Parent Project Muscular Dystrophy. 'The investment and innovation in DMD are delivering, and this is a prime example of how the accelerated approval pathway may swiftly enable a new generation of therapies that address unmet and urgent medical needs.' "The amount of expression of near-full length dystrophin induced by DYNE-251 has not been previously seen with exon 51 skipping agents and is associated with evidence for clinical efficacy,' said Kevin Flanigan M.D., Director, Center for Gene Therapy, Abigail Wexner Research Institute at Nationwide Children's Hospital. 'I look forward to the opportunity to present new functional data and updated safety data at the 2025 MDA Clinical & Scientific Conference.' This updated assessment of the DELIVER trial evaluating DYNE-251 includes new functional data out to 12 months from 6 patients enrolled in the 20 mg/kg Q4W cohort, and 18-month functional data from 6 patients in the 10 mg/kg Q4W cohort (these participants began transitioning to the 20 mg/kg Q4W regimen after month 6). In addition, updated safety data as of February 7, 2025, continue to demonstrate a favorable safety profile for DYNE-251. Key findings from the DELIVER Phase 1/2 trial presentation include: Function: Meaningful and sustained improvements from baseline in multiple functional endpoints were observed in both the 20 mg/kg (selected registrational dose) and 10 mg/kg1 DYNE-251 Q4W cohorts, through 12 and 18 months, respectively. Functional assessments included Stride Velocity 95th Centile (SV95C), North Star Ambulatory Assessment (NSAA), 10-Meter Walk/Run Time (10-MWR), and Time to Rise from Floor. Starting at the 6-month timepoint, the SV95C change from baseline observed in both the 10 mg/kg and 20 mg/kg cohorts of DELIVER exceeded the published proposed minimal clinically important difference (MCID). SV95C is a digital objective outcome measure of ambulatory performance in patients' normal daily environment and is accepted as a primary endpoint for DMD clinical trials in Europe. Dystrophin expression: As previously reported, DYNE-251 demonstrated unprecedented near-full length dystrophin expression as measured by Western blot for patients with DMD who are amenable to exon 51 skipping. At the 6-month time point, patients treated with 20 mg/kg of DYNE-251 Q4W had a mean absolute dystrophin expression of 8.72% of normal (adjusted for muscle content). Dyne has confirmed that the U.S. Food and Drug Administration precedent for using dystrophin as a surrogate biomarker for accelerated approval remains available. Safety and tolerability: DYNE-251 has demonstrated a favorable safety profile based on 54 participants enrolled in the DELIVER trial. Since the prior update provided as of November 21, 2024, the safety profile remains unchanged, and no new treatment-related serious adverse events have been observed.2 970 doses of study drug have been administered to date over a period of 77.1 patient-years of follow-up with some patients followed for up to ~2.5 years. 546 doses of study drug at the 20 mg/kg dose level have been administered to date.3 Key Milestones for the DELIVER Trial Dyne continues to pursue expedited approval pathways globally for DYNE-251 in patients with DMD who are amenable to exon 51 skipping. Dyne has fully enrolled the Registrational Expansion Cohort of 32 patients as part of the DELIVER trial. Data from this cohort are planned for late 2025. Dyne anticipates a potential Biologics License Application (BLA) submission for U.S. accelerated approval in early 2026. Dyne Presentations at the 2025 MDA Clinical & Scientific ConferenceThe new assessment of the DELIVER trial is being presented in an oral presentation 'Safety and Efficacy from the Ongoing Phase 1/2 DELIVER Trial of DYNE-251 in Males with DMD Mutations Amenable to Exon 51 Skipping' on Wednesday, March 19, at 8:30-8:45 a.m. CT by Kevin Flanigan, M.D., Director, Center for Gene Therapy, Abigail Wexner Research Institute of Nationwide Children's Hospital in Columbus, Ohio and Principal Investigator for the DELIVER Trial. A poster with the same title will be available starting at 6:00 p.m. CT Sunday, March 16, 2025, through Tuesday, March 18, 2025, in the conference exhibit hall.

BMO Capital Initiates Coverage on Dyne Therapeutics With Outperform Rating
BMO Capital Markets initiated coverage on Dyne Therapeutics (DYN, Financials) with an Outperform rating and a $50 price target, suggesting a strong upside from the company's current share price of $12.03. Warning! GuruFocus has detected 3 Warning Signs with DYN. Using its TfR1-targeted delivery system, Dyne focuses in creating therapies for neuromuscular disorders. Key clinical initiatives of the business include its myotonic dystrophy type 1 therapy, now in Phase I/II studies, and its Duchenne muscular dystrophy treatment, which might be commercialized by 2026. The FDA's ruling on Dyne's DM1 therapy is a main determinant of her market course. The date of clearance might affect its capacity to access the market in relation to Avidity, a rival company in the field. Analysts advise Dyne may set itself apart by providing a therapy with advantages for central nervous systems. With a current ratio of 15.6 and a market capitalization of $1.37 billion, the firm shows good liquidity. With a beta of 1.11, it has only little connection with the larger market. Some analysts see a possible buying chance in the stock as it has down 51.19% year to date. Important forthcoming events include possibly accelerated approval applications for DYNE-251 and DYNE-101 in 2026. Early January 2025 will also include results from the DM1 Phase 1/2 ACHIEVE study, which will offer information on functional outcomes and splicing repair. Investor mood is still divided; substantial upward potential depends on clinical benchmarks and regulatory clearance routes. Although concerns still relate to regulatory choices and competitive market positioning, analysts stress the company's strong liquidity and pipeline developments.
