Objective

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.

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.

Eligibility

The CANYON Study including the adolescent cohorts are fully enrolled.

GRAND CANYON eligibility is listed below.

Key Inclusion Criteria:

  1. Adults (aged 18 to 50 years, inclusive) with a documented dystrophin mutation and phenotype consistent with Becker muscular dystrophy, and history of being ambulatory beyond 16 years of age without steroids; history of being ambulatory beyond 18 years of age with steroids.

  2. Able to complete the 100-meter timed test in < 200 seconds with or without use of mobility aid devices.

  3. Able to perform the North Star Ambulatory Assessment scale and achieve a score of 5 to 32, inclusive.

Key Exclusion Criteria:

  1. Medical history or clinically significant physical examination/laboratory result that, in the opinion of the investigator, would render the participant unsuitable for the study. This includes contraindications to magnetic resonance imaging such as non-compatible implanted medical devices or severe claustrophobia.

  2. Cardiac echocardiogram ejection fraction < 40%

  3. Forced vital capacity predicted

Participate in a study

Here are some general steps to consider when participating in a research study:

  1. Step
    1

    Contact the research team

    Call or email the research team listed within the specific clinical trial or study to let them know that you're interested. A member of the research team, such as the researcher or study coordinator, will be available to tell you more about the study and to answer any questions or concerns you may have.

    Get screened to confirm eligibility

    You may be asked to take part in prescreening to make sure you are eligible for a study. The prescreening process ensures it is safe for you to participate. During the prescreening process, you will be asked some questions and you may also be asked to schedule tests or procedures to confirm your eligibility.

  3. Step
    3

    Provide your consent to participate

    If you are eligible and want to join the clinical trial or study, a member of the research team will ask for your consent to participate. To give consent, you will be asked to read and sign a consent form for the study. This consent form explains the study's purpose, procedures, risks, benefits and provides other important information, such as the study team's contact information.

  4. Step

    Participate

    If you decide to participate in a clinical trial or study, the research team will keep you informed of the study requirements and what you will need to do to throughout the study. For some trials or studies, your health care provider may work with the research team to ensure there are no conflicts with other medications or treatments.
