PALO ALTO, Calif., May 20, 2022 (GLOBE NEWSWIRE) -- BridgeBio Pharma, Inc. (Nasdaq: BBIO) and affiliate company Phoenix Tissue Repair, which is focused on advancing a novel systemic treatment for recessive dystrophic epidermolysis bullosa (RDEB), announced data from the Phase 2 trial of PTR-01, an intravenously-administered recombinant collagen 7 (rC7) protein replacement therapy, in patients with recessive dystrophic epidermolysis bullosa (RDEB). The data are being shared in a poster at the Society for Investigative Dermatology (SID) Annual Meeting 2022 between May 18 - 21, 2022 in Portland, Oregon.
RDEB is a rare genetic disorder caused by mutations in the gene encoding collagen type VII (C7) and is one of the most severe forms of epidermolysis bullosa, characterized by severe and painful skin blistering, as well as extreme fragility and scarring of mucous membranes throughout the body. There is currently no known cure or effective treatment available for patients suffering from this disease.
"In patients with recessive dystrophic epidermolysis bullosa (RDEB) even minor friction or trauma can cause debilitating blistering, tearing and scarring of the skin, along with severe pain and itching. Our data shows that treatment with PTR-01 led to rapid, consistent, and durable wound healing," said Sanuj K. Ravindran, M.D., executive chairman of Phoenix Tissue Repair. "We are hopeful that by addressing the root cause of this rare disease, we will be able to provide a treatment beyond daily wound care and pain management for patients in need."
