Trial of Oral Valproic Acid for Retinitis Pigmentosa — VPA  

Retinitis Pigmentosa Clinical Trial

Official title:
A Phase II Multiple Site, Randomized, Placebo-Controlled Trial of Oral Valproic Acid for Autosomal Dominant Retinitis Pigmentosa

Clinical Trial Summary

The objectives of this study are to evaluate the efficacy of Valproic Acid (VPA) to both slow the progression of visual function loss and/or to restore visual function in patients with Autosomal Dominant Retinitis Pigmentosa (RP) and to collect safety and tolerability information.

Clinical Trial Description

Retinitis Pigmentosa (RP) is an incurable and untreatable group of heterogeneous retinal degenerative diseases that cause severe visual loss. There is currently no therapeutic that substantially slows the progression of this disease, and certainly none that can restore vision in RP patients. The Valproic Acid (VPA) study is designed as a six-site, interventional, prospective, randomized, placebo controlled, double-blinded study of 90 participants to evaluate the efficacy of oral Valproic Acid to both slow the progression of visual function loss and/or to restore visual function in patients with an Autosomal Dominant RP genetic mutation and to collect safety and tolerability information. Patients that participate in the study will be randomized to either placebo or VPA in a 1:1 ratio. ;
