• Dyne Therapeutics has finished enrolling patients in the registrational expansion cohort of its Phase 1/2 ACHIEVE trial for zeleciment basivarsen in myotonic dystrophy type 1 (DM1).
• This moves the DM1 program into a pivotal stage that sets the timeline for Dyne’s next major regulatory filing and potential launch plans.
• Topline data from the ACHIEVE trial are expected in early 2027, supporting a planned U.S. Accelerated Approval submission.

For investors watching NasdaqGS:DYN, the ACHIEVE milestone adds a second late stage program alongside the Duchenne muscular dystrophy work that has drawn most of the attention so far. The stock recently closed at $18.41, with a return of 31.6% over the past year and 36.8% over the past 3 years, while the 5 year figure is down 11.5%.

This DM1 step gives Dyne Therapeutics a more clearly defined clinical and regulatory path in another rare neuromuscular disease where patients currently have no approved treatment options. With a stated timetable for pivotal data and a planned Accelerated Approval submission, investors can now track two separate programs with specific regulatory decision points identified over the next few years.

Key Considerations

• 📊 Completion of ACHIEVE enrollment turns the DM1 program into a defined registrational path, so the stock now reflects two late stage rare disease assets instead of one.
• 📊 Watch the timing and content of FDA interactions around the planned Accelerated Approval filing, as well as any updates to cash runway and share count.
• ⚠️ Dyne currently reports no revenue and has recently diluted shareholders, so funding needs around extended trials and a potential launch are key risks to track.
