Orphan Status for Abeona Therapeutics Gene Therapy

Share

FDA has granted Abeona Therapeutics an Orphan Drug Designation for its EB-101 gene therapy program for patients with dystrophic epidermolysis bullosa, including recessive dystrophic epidermolysis  bullosa (RDEB), which are life-threatening genetic skin disorders characterized by skin blisters and erosions that cover the body. In a Phase 1/2 clinical trial, EB-101 was administered to non-healing chronic wounds on each subject and assessed for wound healing at predefined time points over years, according to the company. Clinical data were recently presented at the Society of Investigative Dermatology conference, and demonstrated that EB-101-treated wounds were significantly healed (greater than 50% healed) for more than two years post-administration, it adds.


EB-101 is an autologous, ex-vivo gene therapy in which COL7A1 is transduced into autologous keratinocytes for treating RDEB. Patients with RDEB lack functional type VII collagen owing to mutations in the gene COL7A1, the main component of anchoring fibrils, which stabilize the dermal-epidermal basement membrane.
