Roche’s update on clinical hold in Duchenne muscular dystrophy

On the 18th March Sarepta announced the sad news regarding a young man with Duchenne muscular dystrophy who passed away following treatment with delandistrogene moxeparvovec, having suffered acute liver failure. There is still an ongoing assessment and analysis of information following this sad event.
The European Medicines Agency (EMA) has requested a temporary clinical hold on Study 104 (NCT06241950), Study 302 (ENVOL, NCT06128564), and Study 303 (ENVISION, NCT05881408) until the analysis into the cause of death is complete. Please find additional information about each of these studies below.
Roche is pausing enrollment and dosing of participants in these three studies at EU country study sites. For the Roche-sponsored ENVOL study enrollment and dosing is also being paused in the UK. Patient safety monitoring for already enrolled participants and ongoing collection of data will continue
Patient safety and well-being are Roche’s top priority and they will be collaborating closely with EMA to this effect.
