Phase 2 Study to Test the Safety and Effectiveness of Oral VX-01 in Adults with Moderate to Severe Non-Proliferative Diabetic Retinopathy

What this Trial Is About

Researchers are studying the use of VX-01, an oral medication, to treat people with moderate to severe Non-Proliferative Diabetic Retinopathy NPDR, a condition related to diabetes affecting the eyes. This Phase 2 clinical trial aims to evaluate how effective and safe VX-01 is compared to a placebo over one year of treatment, including how the body processes the drug and its effects on the disease. Participants will be randomly assigned to one of two groups one group will receive VX-01 tablets at a dose of 150 mg twice daily, and the other group will receive placebo tablets twice daily. The treatment period lasts 52 weeks, followed by a 12-week follow-up after treatment ends. The study is double-masked, meaning neither participants nor study staff know which treatment is being taken during the trial. During the study, participants will have their vision and eye health regularly assessed using standardized tests such as the Early Treatment Diabetic Retinopathy Study ETDRS letter score and diabetic retinopathy severity scores. Safety will be monitored by tracking any adverse events. Participants must attend scheduled visits for evaluations and agree to avoid other investigational studies during the trial. The main goal is to see how VX-01 affects diabetic retinopathy after one year of daily treatment.
