Merck's eye drug met the vision benchmark, but eye complications were more frequent
Merck's experimental eye drug, remigromig, met its primary endpoint in a Phase 2b/3 trial for diabetic macular edema (DME), showing non-inferior visual acuity compared to ranibizumab. However, it had a higher rate of adverse events related to proliferative diabetic retinopathy. The company plans to discuss the results with regulators and continue evaluating the drug in ongoing studies.
