The investigational Duchenne muscular dystrophy (DMD) therapy, CAP-1002, continues to be beneficial and well tolerated in the long term, according to results from the open-label extension study of the phase 2 HOPE-2 trial (HOPE-2-OLE).
These results will be presented at the 2023 Muscular Dystrophy Association (MDA) Clinical & Scientific Conference taking place from March 19 to 22, 2023 in Dallas, TX.

“CAP-1002 demonstrates novel, clinically meaningful, and cumulative preservation of upper limb function by potentially modifying the underlying disease,” the authors of the study wrote.
During HOPE-2-OLE, 13 patients from the HOPE-2 trial (6 who received CAP-1002 and 7 who received placebo) were treated with CAP-1002 for 18 months after a gap phase of 12 months, which allowed the evaluation of patients both on and off treatment.
The results showed significant differences between patients participating in HOPE-2-OLE and those given a placebo during HOPE-2 in terms of upper limb performance, reinforcing the results obtained in HOPE-2.
Moreover, the progression of the disease slowed significantly among patients given a placebo during HOPE-2 once CAP-1002 was initiated in the extension phase. This led to a decrease in the between-group difference observed in the original HOPE-2 trial.
“CAP-1002 slows upper limb functional decline in DMD by modifying disease,” the researchers concluded.
DMD is a rare genetic disease and a type of muscular dystrophy caused by a mutation in the gene coding for the essential muscle protein, dystrophin. It is characterized by muscle wasting and degeneration.
CAP-1002 is an investigational therapy being developed by Capricor Therapeutics based on cardiosphere-derived cells that can modify the activity of the immune system to drive cellular repair and regeneration. The experimental treatment has been granted Orphan Drug designation for DMD.
