简要总结
This is a single-center, single-arm, interventional phase 1 trial to evaluate the safety and tolerability of local injection of induced pluripotent stem cell (iPSC)- derived CD54+ allogeneic muscle progenitor cells in individuals with Duchenne muscular dystrophy (DMD)

研究组 & 干预措施
Arm B: MyoPAXon 50 x 10^6
MyoPAXon will be delivered via open intramuscular (IM) injection into a single EDB muscle for each participant as a one-time dose. The participants will be started on tacrolimus 1 week prior to dosing and stay on the maintenance dose on a BID schedule for 3 months after injection
干预措施: Tacrolimus (Drug)
Arm C: MyoPAXon 100 x 10^6
MyoPAXon will be delivered via open intramuscular (IM) injection into a single EDB muscle for each participant as a one-time dose. The participants will be started on tacrolimus 1 week prior to dosing and stay on the maintenance dose on a BID schedule for 3 months after injection
