Facioscapulohumeral Muscular Dystrophy clinical trials at UC Irvine

The purpose of this study is to evaluate the pharmacodynamics, safety, tolerability, pharmacokinetics, and efficacy of RO7204239, a humanized monoclonal antibody that binds to human latent myostatin, in ambulant adult participants with facioscapulohumeral muscular dystrophy (FSHD).

This is a study to evaluate the safety and efficacy of losmapimod in treating participants with Facioscapulohumeral Muscular Dystrophy (FSHD). Participants diagnosed with Facioscapulohumeral muscular dystrophy type 1 (FSHD1) or Facioscapulohumeral muscular dystrophy type 2 (FSHD2) will participate in Part A (Placebo-controlled treatment period) and will be randomized in a 1:1 ratio to receive losmapimod 15 milligrams (mg) or placebo orally twice daily (BID). Upon completion of Part A, participants will have the option to rollover into Part B (open-label extension) to evaluate the long-term safety, tolerability, and efficacy of losmapimod and will receive losmapimod 15 mg orally BID.

This study is an open-label extension to evaluate the safety and tolerability of long-term dosing of Losmapimod in patients with FSHD1 who participated in the ReDux4 study.
