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, over a period of approximately 60 months. Following completion of the initial open-label phase (Month 60), subjects who have completed all Month 60 assessments will be eligible to continue into a long-term open label extension (LT-OLE) period and can continue to receive deramiocel once every 3 months until deramiocel is commercially available or the sponsor terminates the study, or the subject withdraws consent or study participation is terminated by the sponsor. Subjects 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 deramiocel. 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, 60, and all LT-OLE visits. 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, 57, and at all LT-OLE 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, 57, with continued dosing in the LT-OLE visits. 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.

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, over approximately a period of 60 months. Additional analyses of efficacy and safety will be conducted in the subsequent Long Term Open-Label Extension (LT-OLE) phase of the study. 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, 60, and all LT-OLE visits (± 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, and at all LT-OLE visits. 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, 57 trial visits. Continued dosing in the LT-OLE phase will begin at LT-OLE Visit 1, which may overlap with Month 60 of the initial OLE phase/LT-OLE Visit 1, in some cases. 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.
