- Conditions
- Facioscapulohumeral Muscular Dystrophy (FSHD)
- Interventions
- Registration Number
- NCT04264442
- Lead Sponsor
- Fulcrum Therapeutics
- Brief Summary
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.
- Detailed Description
This study is an open-label extension study to evaluate the safety and tolerability of long-term dosing of Losmapimod in patients with FSHD1 who participated in the ReDux4 study.
This study is a multi-center clinical trial. It will be conducted in North America, Canada and Europe. Only patients who participated and competed all study procedures in the ReDUX4 Study treatment period will be eligible to participate in this open label extension study.
Patients who complete the randomized, placebo-controlled portion of the study will have the option to roll over into the open-label extension study.
Patients will receive 15 mg of losmapimod by mouth twice daily for a total of 30 mg by mouth daily. All patients will attend clinic visits approximately every 12 weeks.
Participation in this open-label extension study will continue until 90 days after losmapimod becomes commercially available, the patient withdraws from the study, or the Sponsor decides to close the study.
The primary endpoint of the study is to evaluate the safety and tolerability of long-term dosing of losmapimod in patients with FSHD.
