Brief Summary:

A study of EDG-5506 in Becker muscular dystrophy (known as CANYON) and pivotal cohort (known as GRAND CANYON). The EDG-5506-201 CANYON study was expanded to include an additional 120 adult participants in a cohort called GRAND CANYON, that is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the safety and efficacy of EDG-5506 in adults with Becker.

CANYON is fully enrolled; GRAND CANYON is currently enrolling.


Condition or disease Intervention/treatment Phase
Becker Muscular Dystrophy Drug: EDG-5506 10 mg Drug: EDG-5506 5 mg Drug: EDG-5506 12.5 mg Drug: Placebo Phase 2

Detailed Description:

The EDG-5506-201 protocol was amended to include an additional cohort thus consists of two parts.

Part 1: CANYON is a double-blind, randomized, placebo-controlled design to investigate the effect of EDG-5506 on the safety, pharmacokinetics, biomarkers, and functional measures. Approximately 32 adults and 18 adolescents with Becker muscular dystrophy are planned to enroll in this study. This study will have up to a 4-week Screening period, a 12-month Treatment period, followed by a 4-week follow-up period.

Approximately 32 adult participants will randomize to Cohort 1 or Cohort 2 in a 1:1 ratio then each cohort will further randomize to EDG-5506 or placebo in a 3:1 ratio.

Approximately 9 adolescent participants will enroll in Cohort 4 and randomize in a 2:1 ratio to EDG-5506 or placebo. Cohort 5 will randomize an additional 9 participants in a 2:1 ratio to either EDG-5506 or placebo after Cohort 4.

CANYON is now fully enrolled.

Part 2: GRAND CANYON or Cohort 6 is a double-blind, randomized, placebo-controlled design to investigate the safety and efficacy of EDG-5506 in adults with Becker muscular dystrophy after 18 months of treatment. Approximately 120 adults with Becker muscular dystrophy are planned to enroll in this study. This study will have up to a 4-week Screening period, an 18-month Treatment period, followed by a 4-week follow-up period.

Approximately 120 adult participants will be randomized in Cohort 6 in a 2:1 ratio either to EDG-5506 or placebo.
