Safety, Tolerability, PK, and PD Study of PGN-EDODM1 in Participants With Myotonic Dystrophy Type 1 (FREEDOM-DM1)
February 28, 2024 updated by: PepGen Inc
A Phase 1 Placebo-Controlled Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single-Ascending Doses of PGN-EDODM1 in Adult Participants With Myotonic Dystrophy Type 1 (FREEDOM-DM1)
The primary purpose of the study is to evaluate the safety and tolerability of single intravenous (IV) doses of PGN-EDODM1 administered to participants with Myotonic Dystrophy Type 1 (DM1).
The study consists of 2 periods: A Screening Period (up to 30 days) and a Treatment and Observation Period (16 weeks).
