Modulation of SERCA2a of Intra-Myocytic Calcium Trafficking in Cardiomyopathy Secondary to Duchenne Muscular Dystrophy (MUSIC-DMD)

February 26, 2025 updated by: Sardocor Corp.

A Phase 1b, Open-Label, Controlled Trial Evaluating the Safety and Efficacy of SRD-001 (AAV1/SERCA2a) in Subjects With Cardiomyopathy Secondary to Duchenne Muscular Dystrophy

This research study is testing whether an experimental drug, called SRD-001, is safe and helps the weakened heart of patients with Duchenne muscular dystrophy (DMD) regain its ability to effectively pump blood to the rest of the body. SRD-001 is a form of gene therapy. The goal of SRD-001 gene therapy is to provide the heart muscle cells with extra copies of the SERCA2a gene so that they can produce more SERCA2a protein to help the heart muscle cells squeeze/contract better. Researchers will compare SRD-001 treated participants with no-treatment participants; all participants will continue to take their current heart medications. All participants will be followed very closely for 2 years and undergo cardiac magnetic resonance imaging of their heart at baseline, year 1 and year 2 along with assessment of upper limb function and lung function. After the 2 years of close follow-up, all participants will roll over into long-term follow-up where they will be called biannually for information on their current medical status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This phase 1b, multi-center, non-randomized, open-label, ascending dose escalation, no-intervention-control trial will assess the safety and explore the efficacy of SRD-001 administered as a one-time antegrade epicardial coronary artery infusion for the treatment of participants with cardiomyopathy secondary to DMD. SRD-001 is an AAV1 vector expressing the transgene for SERCA2a. Twelve participants will be assigned to either active treatment with SRD-001 or no-intervention based upon their neutralizing antibody status. The objectives of the trial are (1) to evaluate the safety of a one-time intracoronary administration of SRD-001 in participants with cardiomyopathy due to DMD; and (2) to explore the impact of SRD-001 on heart and skeletal muscle function and quality of life. After screening to determine eligibility, participants will be sequentially assigned to low dose SRD-001, high dose SRD-001 or no-intervention. Participants assigned to active treatment with SRD-001 will under cardiac catheterization and angiography just prior to the intracoronary infusion of SRD-001 and spend overnight int he hospital for observation.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
