Oculis OCS-01 Trials Fail to Meet Primary Endpoint
- Trial Results: Oculis Holding AG's OCS-01 eye drops failed to meet the primary endpoint in the Phase 3 DIAMOND-1 and DIAMOND-2 trials for diabetic macular edema, as the mean change in best corrected visual acuity (BCVA) at Week 52 was not achieved, indicating a lack of efficacy.
- Secondary Endpoint Failure: The proportion of patients achieving a 15-letter gain in BCVA also fell short of expectations in both studies, suggesting limited effectiveness of OCS-01 in improving vision, which may impact future market acceptance.
- Safety Assessment: Despite the efficacy shortcomings, OCS-01 was well tolerated with no unexpected adverse events reported, and the overall safety profile was consistent with earlier studies, indicating favorable tolerability that could support future research.
- Stock Price Reaction: Following the trial results, Oculis's stock price plummeted, closing at $22.71 on May 29, down 23.42%, and further declining to $15.01 in after-hours trading, a drop of 33.89%, reflecting market pessimism regarding the drug's prospects.
