Recessive Dystrophic Epidermolysis Bullosa (RDEB)


Phase 3 VIITALTM Clinical Trial of EB-101

A multi-center, randomized clinical trial assessing 10-15 patients with recessive dystrophic epidermolysis bullosa (RDEB) treated with autologous, gene-corrected cell therapy EB-101 compared to intra-patient untreated wounds.


Enrollment expected to begin in Q4 2019.

Phase 1/2 Clinical Trial of EB-101

A single-center randomized clinical trial assessing autologous, gene-corrected cell therapy EB-101 for wound healing in patients with RDEB.

About the Phase 1/2 Study

Recessive Dystrophic Epidermolysis Bullosa, or RDEB, is caused by a defect in the COL7A1 gene resulting in the inability to produce Type VII collagen, which plays an important role in anchoring the dermal and epidermal layers of the skin. The study involves gene transfer into a majority of cells in the outer layer of skin, using an ex vivo approach. Investigators will biopsy skin tissue, grow and multiply the cells, and then insert the correct type VII collagen gene. Inserting the gene may provide the cells with the properties to grow and develop normal skin. This process of inserting the correct gene, or "gene transfer," uses a vector virus. The vector is made so that it only delivers the gene and it should not spread to other parts of the body, which investigators monitor during the study. After cells have received gene transfer, they are grown into a skin patches of cells that look like a plastic film, before being transplanted back onto the patient. After treatment, patients are followed for 24 months to assess safety and efficacy.
