• As of June 30, the Company received 121 Patient Start Forms of which 30 start forms were generated for patients with dominant dystrophic epidermolysis bullosa. The Company will continue to report on the number of Patient Start Forms submitted to the Company for the first three quarters following VYJUVEK approval and will transition to reporting on the number of Patients on Therapy beginning in the first quarter of 2024.

Indication

VYJUVEK is a herpes-simplex virus type 1 (HSV-1) vector-based gene therapy indicated for the treatment of wounds in patients six months of age and older with dystrophic epidermolysis bullosa with mutation(s) in the collagen type VII alpha 1 chain (COL7A1) gene.
