Craig M. McDonald, MD, on Developing Gene Therapy for Different Populations of DMD


The principal investigator of the HOPE-2 trial discussed results of the trial in the non-ambulatory population of patients with Duchenne muscular dystrophy.

“In the HOPE-2 trial we focused on the non-ambulatory population with Duchenne, which has largely been ignored in previous clinical trials. Most clinical trials in Duchenne are focused on the ambulatory population and these patients have largely been at the back of the bus as far as some of the more innovative therapeutics go.”

The allogeneic cardiosphere-derived cell therapy CAP-1002 (Capricor Therapeutics) has yielded statistically significant clinical benefits in non-ambulatory patients with Duchenne muscular dystrophy (DMD), according to newly released data from the phase 2 HOPE-2 trial open-label extension (OLE; NCT04428476).1 The trial met its primary endpoint of improvement on Performance of the Upper Limb 2.0 (P = .02) The OLE evaluated 12 patients out of the original 20 from the HOPE-2 trial (NCT05126758). Capricor has also just dosed the first patient in the phase 3 HOPE-3 trial (NCT05126758) of CAP-1002 in patients with late-stage DMD.2

CGTLive spoke with Craig M. McDonald, MD, chair, Department of Physical Medicine & Rehabilitation and professor, Department of Pediatrics and Physical Medicine & Rehabilitation, UC Davis Health, to learn more about the data seen in the OLE. He discussed the importance of assessing therapies in the non-ambulatory population of patients with DMD.
