- Brief Summary
This Phase 2, multi-center, open-label extension trial will provide deramiocel (CAP-1002) to subjects that were enrolled in the HOPE-2 trial and completed 12 months of follow-up. The trial will explore the safety and efficacy of twenty intravenous administrations of deramiocel, each separated by three months.

Subjects will complete trial assessments at Screening; Day 1; Months 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, and 60. Safety and efficacy assessments will be conducted prior to deramiocel administration at the Day 1, Months 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, and 57 trial visits, unless otherwise indicated.
All deramiocel infusions will be conducted in an outpatient setting at the investigative site on Day 1 and Months 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, and 57.

- Detailed Description
This Phase 2, multi-center, open-label extension trial will provide deramiocel (CAP-1002) to subjects that were enrolled in the HOPE-2 trial and completed 12 months of follow-up. The trial will explore the safety and efficacy of twenty intravenous administrations of deramiocel, each separated by three months. Subjects will undergo a targeted screening during a 30-day screening period to determine eligibility based on protocol inclusion and exclusion criteria.
Eligible subjects will undergo baseline safety and efficacy assessments on Day 1 prior to their first infusion of deramiocel. Administration of deramiocel (Day 1) should occur within a maximum of 30 days following confirmation of eligibility.
Subjects will complete trial assessments at Screening; Day 1; Months 3, 6, 9, 12 (± 14 days, each), 15, 18, 21, 24, 27, 30, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, and 60 (± 21 days, each). Safety and efficacy assessments will be conducted prior to deramiocel administration at the Day 1, Months 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, and 57 trial visits, unless otherwise indicated.
All deramiocel infusions will be conducted in an outpatient setting at the investigative site on Day 1 and Months 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, and 57. Prior to each deramiocel administration, medications will be administered to the subject as determined by the Investigator based on the pre-treatment guidelines as outlined in the protocol and/or institutional protocols to minimize the risk of potential severe allergic reactions such as anaphylaxis. Subjects 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. If clinically indicated, an unscheduled in-person visit will be performed at the investigative site with targeted assessments based on presentation of signs and symptoms following any infusion.

- Primary Outcome Measures
Name Time Method Number of Participants With Treatment-Emergent Adverse Events (TEAEs) From Baseline Through Month 12 Baseline up to Month 12 Adverse event (AE) is defined as any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. Serious AE: an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAE: AE with onset after start of treatment or with onset date before the treatment start date but worsening after the treatment start date. TEAEs included both serious and non-serious TEAEs.
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) by Severity From Baseline Through Month 12 Baseline up to Month 12 Severity of adverse events (AE) were assessed by the investigator as Grade 1 = Mild (Transient or mild discomfort; no limitation in activity; no medical intervention/therapy required), Grade 2 = Moderate (Mild to moderate limitation in activity - some assistance may be needed; no or minimal medical intervention/therapy required), Grade 3 = Severe (Marked limitation in activity, some assistance usually required; medical intervention/therapy required and often requiring hospitalization or prolongation of hospitalization), Grade 4 = Life-threatening (Extreme limitation in activity, significant assistance required; significant medical intervention/therapy required; hospitalization, prolongation of hospitalization, or hospice care) and Grade 5 = Death.
Change From Baseline in Functional Capacity as Assessed by Performance of the Upper Limb Test, Version 2 (PUL 2.0) Total Score. Baseline, Month 12 PUL 2.0 scale is a 22-item scale used to assess the change that occurs in motor performance of the upper limb overtime from when a participant is still ambulant to the time participant loses all arm function when non-ambulant. PUL 2.0 includes an entry item to define broad starting functional level and 22 items subdivided into shoulder level (six items), mid-level (nine items), and distal level (seven items). Each dimension (shoulder, mid, distal) can be scored separately. There is maximum score of 12 for shoulder level, 17 for mid-level, and 13 for distal level. The total score was calculated by adding three level scores and ranged from 0-42. Higher score indicates better upper limb function.
