8 participants in 4 patient groups

Arm A: MyoPAXon 25 x 10^6
Experimental group
Description:
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
Treatment:
Drug: MyoPAXon
Drug: Tacrolimus
Arm B: MyoPAXon 50 x 10^6
Experimental group
Description:
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
Treatment:
Drug: MyoPAXon
Drug: Tacrolimus
Arm C: MyoPAXon 100 x 10^6
Experimental group
Description:
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
Treatment:
Drug: MyoPAXon
Drug: Tacrolimus
Arm D: MyoPAXon 200 x 10^6
Experimental group
Description:
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
