This Phase 2, multi-center, open-label extension trial will provide CAP-1002 to participants who were randomized to the Usual Care treatment group of the HOPE-Duchenne study (NCT02485938) and completed 12 months of follow-up. The trial will assess the safety and efficacy of two intravenous administrations of CAP-1002, each separated by three months.
Participants with documented enrollment in the Usual Care treatment group of the HOPE-Duchenne study and completion of study follow-up through Month 12 were eligible for this study. Participants will undergo a targeted screening during a 30-day screening period, eligible subjects will then undergo baseline safety and efficacy assessments on Day 1 prior to their first infusion of CAP-1002. All CAP-1002 infusions will be conducted in an outpatient setting at the investigative site on Day 1 and at Month 3. Participants will be observed in the outpatient setting for at least two hours post-infusion and then discharged the same day if medically cleared by the site Investigator.

Number of Participants Experiencing Acute Respiratory Decompensation
Acute respiratory decompensation is defined as an unexplained rapid deterioration of the participant's condition with increasing shortness of breath requiring oxygen supplementation. Acute respiratory decompensation within 2 hours following investigational product (IP) administration will be reported.
Time frame: 2 hours post-dose on Day 1 and Month 3
Number of Participants With Hypersensitivity Reactions
Hypersensitivity reaction is defined as a clinical syndrome including, but not limited to, fever, leukocytosis, or rash with onset \<= 2 hours post-infusion and lasting \< 24 hours, in the absence of clinical signs of concomitant infection.
Time frame: From Day 1 up to Month 6
All-cause Mortality
Number of deaths due to any cause will be reported.
Time frame: From Day 1 up to Month 6
Number of Treatment-emergent Adverse Events (TEAEs) Related to Investigational Product or Administration and Serious Adverse Events (SAEs)
An adverse events (AEs) is any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. TEAEs are defined as AEs occurring after the initiation of the IV catheter placement for the initial dose of IP. TEAEs related to investigational product or administration are reported for this outcome measure. A SAE is defined as an AE that results in any of the following outcomes: Death; life-threatening adverse event; Inpatient hospitalization or prolongation of existing hospitalization; persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions; congenital anomaly/birth defect.
Time frame: From Day 1 up to Month 6
Number of Participants With Immune Sensitization Syndrome
Immune sensitization syndrome shall be defined as: (a) clinical signs and symptoms consistent with systemic inflammation (e.g., fever, leukocytosis, rash, or arthralgia) with onset \>= 24 hours post infusion and the absence of clinical signs of concomitant infection, and (b) elevation of anti-human leukocyte antigen (HLA) antibodies against the donor cells (i.e., DSAs), detected \<= 30 days following onset of syndrome, of (i) \>= 2000 mean fluorescent intensity (MFI) if baseline MFI \<= 1000, or (ii) \>= 2 times baseline otherwise.
