Opus Genetics Advances Gene Therapies for Inherited Retinal Diseases, Secures FDA Alignment for Phase 3 Trial
Opus Genetics is making significant strides in developing gene therapies for inherited retinal diseases (IRDs), specifically OPGx-LCA5 for LCA5-associated IRD and OPGx-BEST1 for BEST1-associated IRD. According to Dr. George Magrath, CEO of Opus Genetics, the OPGx-LCA5 program, targeting an ultra-rare disease affecting approximately 200 U.S. children, has shown promising results. All six participants treated to date (three pediatric and three adult) demonstrated improvement across various measures, including full-field stimulus threshold (FST) testing, best-corrected visual acuity (BCVA), virtual-reality maze tests, and microperimetry. Retinal sensitivity improved by about 1.5 log units at both blue and red wavelengths. The company has also secured FDA alignment for an eight-participant Phase 3 registrational trial for OPGx-LCA5, utilizing a 6-month pretreatment period where each participant serves as their own control. The OPGx-BEST1 program aims to restore bestrophin-1 channel function in the retinal pigm...
