Disappointing results from phase 3 FSHD clinical trial

12 September 2024

Today, pharamaceutical company Fulcrum Therapeutics announced high level results from its phase 3 clinical trial of the drug losmapimod – called the REACH study. The company reported that the drug failed to show improvements in several of the tests carried out in the trial over a 48-week period.

We’re sad to inform you that because of these disappointing results the company is suspending further development of the drug.

The REACH Phase 3 clinical trial was a global study that aimed to test if losmapimod was safe and effective for use in people living with facioscapulohumeral muscular dystrophy (FSHD). While there were no concerns about its safety, no improvement was observed in participants who received losmapimod compared to those who received a control drug (placebo).

The trial enrolled 260 participants across the world, including the UK. If you or your family member has been involved in the study, we recommend you contact the study site for further information.

We know this comes as a huge disappointment to the FSHD community, and if you’re in need of support, please call our helpline team on  0800 652 6352 or email  info@musculardystrophyuk.org.
