RAHWAY, N.J. - Merck & Co. Inc. (NYSE: MRK) announced today the discontinuation of a specific arm in its Phase 3 KeyVibe-010 trial, which was assessing a combination therapy involving vibostolimab and pembrolizumab in patients with resected high-risk melanoma.
The decision followed a pre-planned analysis indicating that the trial is unlikely to meet the primary endpoint of recurrence-free survival (RFS).
The halted arm of the study was comparing the coformulation of vibostolimab, an anti-TIGIT antibody, with pembrolizumab, Merck's own anti-PD-1 therapy, against pembrolizumab alone. The independent Data Monitoring Committee (DMC) recommended the unblinding of the study after observing a higher discontinuation rate due to immune-mediated adverse experiences in the coformulation arm compared to the monotherapy arm.
Patients currently receiving the coformulation will be offered the option to switch to pembrolizumab monotherapy. Merck remains committed to exploring and advancing treatments for melanoma, including the ongoing Phase 3 V940-001 study in collaboration with Moderna (NASDAQ:MRNA), which is evaluating a neoantigen therapy combined with pembrolizumab.
Despite this setback, Merck's clinical program continues to evaluate the safety and efficacy of the vibostolimab and pembrolizumab coformulation in over 3,000 patients across various cancers. The company has stated that the findings from the KeyVibe-010 study are not expected to impact ongoing Phase 3 trials in lung cancer, where interim safety reviews have not necessitated any changes.
