- Positive Initial Clinical Data from ACHIEVE Trial in DM1 Patients and DELIVER Trial in DMD Patients Demonstrated Proof-of-Concept, Validating the Promise of the FORCE™ Platform and Targeted Delivery to Muscle -
- Strengthened Balance Sheet with
“We’ve had an exciting start to 2024 highlighted by Dyne’s first clinical data demonstrating proof-of-concept in our DM1 and DMD programs that validated the promise of the FORCE™ platform in developing targeted therapeutics for people living with rare muscle diseases. We were thrilled to see dose-dependent results in our ACHIEVE trial in DM1 as well as meaningful improvement in myotonia at the lowest dose, and in our DELIVER trial to exceed the level of dystrophin production reported for the standard of care for DMD exon 51 with a fraction of the dose. The strength of these data formed the foundation of the
Highlights from Clinical Programs
Phase 1/2 ACHIEVE Trial of DYNE-101 in DM1
- In
January 2024 , Dyne reported initial clinical data from the Phase 1/2 ACHIEVE trial of DYNE-101 in adult patients with myotonic dystrophy type 1 (DM1).- The initial efficacy assessment was based on data from 32 patients enrolled in the randomized, placebo-controlled multiple ascending dose (MAD) portion of the trial, including 6-month data from the 1.8 mg/kg (approximate ASO dose) cohort and 3-month data from the 3.4 mg/kg Q4W cohort. DYNE-101 demonstrated a dose-dependent splicing correction as well as an increase in muscle delivery and DMPK knockdown. Patients treated with 1.8 mg/kg Q4W of DYNE-101 also experienced functional improvement in myotonia as measured by video hand opening time (vHOT) and overall improvement in the Myotonic Dystrophy Health Index (MDHI) patient reported outcome, including the fatigue subscale, suggesting potential benefit in the central nervous system.
- Safety and tolerability data were based on 45 patients enrolled through the 5.4 mg/kg Q8W cohort of the MAD portion. DYNE-101 demonstrated a favorable safety profile as of the data cutoff date1.
- The ACHIEVE trial is fully enrolled through the 5.4 mg/kg Q8W cohort and is currently enrolling participants in the 6.8 mg/kg Q8W cohort.
Phase 1/2 DELIVER Trial of DYNE-251 in DMD
- In
January 2024 , Dyne reported initial clinical data from the Phase 1/2 DELIVER trial of DYNE-251 in Duchenne muscular dystrophy (DMD).- The initial efficacy assessment was based on 6-month data from 6 male patients with DMD amenable to exon 51 skipping enrolled in the 5 mg/kg (approximate PMO dose) cohort of the randomized, placebo-controlled MAD portion of the trial. Once every 4-week administration of DYNE-251 reached levels of dystrophin expression, exon skipping and percent dystrophin positive fibers that exceeded levels reported in a clinical trial for the current weekly standard of care for DMD exon 51, eteplirsen, at 6 months2 with a 24-fold lower total PMO dose.
- Safety and tolerability data were based on 37 patients enrolled through the 20 mg/kg cohort of the MAD portion. DYNE-251 demonstrated a favorable safety profile as of the data cutoff date1.
- The DELIVER trial is fully enrolled through the 20 mg/kg Q4W cohort and is currently enrolling participants in the 40 mg/kg Q8W cohort.
Other Business Highlights
- In
January 2024 , Dyne completed an underwritten public offering of 19,722,500 shares of its common stock at a public offering price of$17.50 per share, which included 2,572,500 shares issued upon the exercise in full by the underwriters of their option to purchase additional shares of common stock in the offering. The gross proceeds to Dyne from the offering were approximately$345.1 million , before deducting underwriting discounts and commissions and offering expenses payable by Dyne.
Upcoming Events & Key 2024 Milestones
- Initial data from ACHIEVE and DELIVER reported in
January 2024 will be featured in oral presentations at theMuscular Dystrophy Association (MDA) Clinical and Scientific Conference onMarch 6, 2024 . - Dyne anticipates reporting data from multiple, higher dose cohorts from both the ACHIEVE and the DELIVER trials in the second half of 2024 with the goal of initiating registrational cohorts by the end of 2024.
