WALTHAM, Mass., Oct. 30, 2023 (GLOBE NEWSWIRE) -- Dyne Therapeutics, Inc. (Nasdaq: DYN), a clinical-stage muscle disease company focused on advancing innovative life-transforming therapeutics for people living with genetically driven diseases, today reported financial results for the third quarter of 2023 and provided an update on progress and upcoming milestones for its Phase 1/2 ACHIEVE and DELIVER clinical trials.
“We’ve made tremendous progress in our ACHIEVE and DELIVER trials with more than 72 patients enrolled and over 300 doses administered thus far. To date, the safety profile in the clinic has been favorable for DYNE-101 and DYNE-251 and has supported dose escalation to a combined nine cohorts across both trials. The enthusiasm amongst the DM1 and DMD communities reflects the significant unmet need and the potential for our investigational therapies to deliver transformative outcomes for patients,” said Joshua Brumm, president and chief executive officer of Dyne. “We are moving with great excitement towards reporting initial data from ACHIEVE and DELIVER, including the important biomarker of splicing and functional outcome of myotonia in DM1 and dystrophin in DMD. We look forward to sharing both readouts around the time of the J.P. Morgan Healthcare Conference in early January 2024.”
ACHIEVE Trial of DYNE-101 in DM1
Clinical Update
- ACHIEVE is a Phase 1/2 global clinical trial evaluating DYNE-101 in adult patients with myotonic dystrophy type 1 (DM1) who are 18 to 49 years of age. ACHIEVE, which is designed to be a registrational trial, consists of a 24-week multiple ascending dose (MAD), randomized, placebo-controlled period, a 24-week open-label extension (OLE) and a 96-week long-term extension. The primary endpoints are safety and tolerability, with secondary endpoints of pharmacokinetics and pharmacodynamics, including change from baseline in splicing, as well as measures of muscle strength and function.
- In the MAD portion of ACHIEVE:
- Enrollment is complete in the 1.8 mg/kg (approximate ASO dose) cohort (n=16) evaluating once every four-week dosing and the 3.4 mg/kg cohort evaluating once every four-week dosing (n=16) and every eight-week dosing (n=8). A total of 40 patients have been enrolled in these two cohorts with over 150 doses administered to date.
- All patients who completed the 24-week MAD portion of ACHIEVE have entered the 24-week OLE.
- The safety profile of DYNE-101 supported dose escalation to cohort 3 (up to 6.8 mg/kg), which is currently enrolling participants. Per the protocol, further dose escalation to cohort 4 (up to 10.2 mg/kg) will be based on review of safety data from cohort 3, when available, and the trial overall.
- To date, no participants have demonstrated treatment-emergent anemia and there have been no discontinuations.
Planned Reporting of Initial Data
- In early January 2024 at a company event around the time of the 42nd Annual J.P. Morgan Healthcare Conference, Dyne anticipates reporting from the ACHIEVE trial:
- Safety and tolerability data from multiple cohorts.
- Splicing data and analysis of the video hand opening time (vHOT) myotonia functional assessment from at least the 1.8 mg/kg cohort at 6 months.
DELIVER Trial of DYNE-251 in DMD
Clinical Update
- DELIVER is a Phase 1/2 global clinical trial evaluating DYNE-251 in ambulant and non-ambulant males with Duchenne muscular dystrophy (DMD) who are ages 4 to 16 and have mutations amenable to exon 51 skipping. DELIVER, which is designed to be a registrational trial, consists of a 24-week MAD, randomized, placebo-controlled period, a 24-week OLE and a 96-week long-term extension. The primary endpoints are safety, tolerability and change from baseline in dystrophin levels as measured by Western blot. Secondary endpoints include measures of muscle function, exon skipping and pharmacokinetics.
- In the MAD portion of DELIVER:
- Enrollment is complete through the 10 mg/kg (approximate PMO dose) cohort evaluating once every four-week dosing. A total of 32 patients have been enrolled across the first five cohorts (0.7 mg/kg (n=6), 1.4 mg/kg (n=6), 2.8 mg/kg (n=6), 5 mg/kg (n=6) and 10 mg/kg (n=8)) with over 175 doses administered to date.
- All patients who completed the 24-week MAD portion of DELIVER have entered the 24-week OLE.
- The safety profile of DYNE-251 supported dose escalation to cohort 6 (up to 20 mg/kg), which is currently enrolling participants. Per the protocol, further dose escalation to cohort 7 (up to 40 mg/kg) will be based on review of safety data from cohort 6, when available, and the trial overall.
- To date, no participants have demonstrated treatment-emergent anemia and there have been no discontinuations.
Planned Reporting of Initial Data
- In early January 2024 at a company event around the time of the 42nd Annual J.P. Morgan Healthcare Conference, Dyne anticipates reporting from the DELIVER trial:
- Safety and tolerability data from multiple cohorts.
- Dystrophin expression data from the 5 mg/kg cohort at 6 months.
