NightstaRx and The University of Alberta announce the start of the first Canadian gene therapy study to treat Choroideremia

NightstaRx Ltd ("Nightstar"), the biopharmaceutical company specialising in bringing therapies for retinal dystrophies to patients, announces that the University of Alberta, has begun enrolling and dosing subjects in a Phase II clinical trial of the Company's gene therapy for the treatment of choroideremia (CHM).

This gene therapy approach uses a viral vector known as adeno-associated virus (AAV) to deliver a wild-type copy of the Rab-escort protein 1 (REP-1) gene (AAV2-REP1) into cells of the eye.
