Valproic Acid for Autosomal Dominant Forms of RP


Description: In preclinical studies and limited clinical evaluations, valproic acid has shown the potential to slow the progress of vision loss from autosomal dominant forms of retinitis pigmentosa (RP). Valproic acid is a drug FDA approved for the treatment of seizure disorders. The Foundation Fighting Blindness Clinical Research Institute, the clinical trial support organization of the Foundation Fighting Blindness, is funding a three-year, 90-participant Phase II clinical trial at the Retina Foundation of the Southwest (Dallas) and the University of Utah (Salt Lake City) to evaluate the safety and efficacy of valproic acid. Participants must be at least 18 years of age and have a diagnosis of autosomal dominant retinitis pigmentosa. Participants will be randomized to receive either placebo or valproic acid.

Trial Status: Recruiting participants.
