A phase II randomized vehicle-controlled trial of intradermal allogeneic fibroblasts for recessive dystrophic epidermolysis bullosa.

BACKGROUND: Chronic wounds are a major source of morbidity and mortality in generalized severe recessive dystrophic epidermolysis bullosa (RDEB-GS).

OBJECTIVE: This was a phase II double-blinded randomized controlled trial of intralesional allogeneic cultured fibroblasts in suspension solution versus suspension solution alone for wound healing in RDEB-GS.

METHODS: Adult patients with RDEB-GS were screened for chronic ulcers and reduced collagen VII expression. Up to 6 pairs of symmetric wounds were measured and biopsied at baseline, then randomized to cultured allogeneic fibroblasts in a crystalloid suspension solution with 2% albumin or suspension solution alone. Ulcer size, collagen VII protein and messenger RNA expression, anchoring fibril numbers, morphology, and inflammatory markers were measured at 2 weeks and at 3, 6, and 12 months.

RESULTS: All wounds healed significantly more rapidly with fibroblasts and vehicle injections, with an area decrease of 50% by 12 weeks, compared with noninjected wounds. Collagen VII expression increased to a similar degree in both study arms in wounds from 3 of 5 patients.

LIMITATIONS: The number of patients with RDEB-GS who met inclusion criteria was a limitation, as was 1 trial center rather than multicenter.

CONCLUSIONS: The injection of both allogeneic fibroblasts and suspension solution alone improved wound healing in chronic nonhealing RDEB-GS wounds independently of collagen VII regeneration. This may provide feasible therapy for wound healing in patients with RDEB-GS.
