|Epidermolysis Bullosa Recessive Dystrophic Epidermolysis Bullosa||Biological: EB-101||Phase 3|
Recessive dystrophic epidermolysis bullosa (RDEB) is an ultra-rare, severe inherited blistering skin disease caused by the absence of a protein known as type 7 collagen (C7). There is no approved treatment for RDEB. Only supportive care is currently possible.
This open-label, controlled study will evaluate the efficacy and safety of EB-101 for the treatment of large, chronic, RDEB wounds. The study intervention consists of One-time surgical application of approximately 30 autologous, gene-corrected keratinocyte sheets (EB-101) for the treatment of RDEB wound sites in up to approximately 15 participants. A single EB-101 sheet is able to provide healing to a wound area up to approximately 40cm2. Up to 6 (six) EB-101 sheets may be applied to each patient, depending on the area of existing wounds. Treatment effect will be measured as wound healing at 3 months, with follow up to 6 months post treatment, comparing treated versus matched untreated wound sites. Wound healing will be adjudicated by an independent committee not involved in the study conduct. Patient-reported outcomes and safety will also be collected throughout the study.
The primary analysis for efficacy will be assessed when all patients reach Week 12. Safety and efficacy assessments will be conducted at regular intervals and completed when last patient reaches Week 24 post-treatment.
Upon completion of the 6-month study period, patients will be monitored annually as per standard of care for up to 15 years.
