Roche presents new phase III pivotal data for vamikibart in uveitic macular edema (UME), a serious cause of vision loss

Core Insights - Roche announced positive results from two phase III studies evaluating vamikibart for treating uveitic macular edema (UME), showing potential for rapid vision improvement and reduction in macular thickness [1][2][5] Study Results - The studies, MEERKAT and SANDCAT, demonstrated statistically significant improvements in best corrected visual acuity (BCVA) in the MEERKAT trial, with a 19.9% improvement at 0.25 mg and 36.9% at 1 mg compared to sham [4][6] - In SANDCAT, the improvements were 20.7% at 0.25 mg and 10.9% at 1 mg, with nominal significance [4][6] - Average changes in central subfield thickness (CST) also showed significant reductions, with changes of -58.5 µm and -187.5 µm in MEERKAT and -43.5 µm and -209.7 µm in SANDCAT [6] Safety Profile - Vamikibart was generally well tolerated, with low incidence of treatment-related ocular adverse events and no cases of retinal occlusive vasculitis reported [2][6] - The most common adverse events included conjunctival hemorrhage and raised intraocular pressure, occurring in over 5% of patients [2][6] Treatment Context - UME is a significant cause of vision loss and blindness, particularly in working-age individuals, and current treatments primarily involve steroids, which have notable side effects [2][8] - Vamikibart represents a potential first-in-class non-steroid treatment option targeting interleukin-6 (IL-6), a key cytokine in the inflammatory pathway of UME [9][5] Future Directions - Roche plans to discuss the study data with regulatory authorities globally, indicating a pathway towards potential approval and market introduction of vamikibart [2][5]
