Phase 1/2 ACHIEVE Trial of DYNE-101 in DM1
- 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 (LTE). Enrollment is complete through the 6.8 mg/kg (approximate ASO dose) cohort evaluating once every eight-week dosing. A total of 56 patients have been enrolled in the study with approximately 500 doses administered to date.
- In the upcoming clinical update, Dyne plans to report safety and tolerability data from all enrolled cohorts. Additionally, pharmacokinetic and pharmacodynamic data, including change from baseline in splicing, measures of muscle strength and function, and patient reported outcomes will be shared. Efficacy data will be shared from the 1.8 mg/kg Q4W cohort (n=16) at 12 months, 3.4 mg/kg Q4W cohort (n=16) at 6 months, and 5.4 mg/kg Q8W cohort (n=8) at 3 months.
Phase 1/2 DELIVER Trial of DYNE-251 in DMD
- 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 LTE. Enrollment is complete through the 40 mg/kg (approximate PMO dose) cohort evaluating once every eight-week dosing. A total of 48 patients have been enrolled in the study with approximately 480 doses administered to date.
- In the upcoming clinical update, Dyne plans to report safety and tolerability data from all enrolled cohorts. Additionally, pharmacokinetic and pharmacodynamic data, including dystrophin expression measured by Western blot, will be shared from the 10 mg/kg Q4W cohort (n=8) at 6 months.
