RAHWAY, N.J. - Merck & Co., Inc. (NYSE: MRK) has terminated its Phase 3 KeyVibe-008 trial for the treatment of extensive-stage small cell lung cancer (ES-SCLC), following recommendations from an independent Data Monitoring Committee (DMC).
The study, which was comparing a fixed-dose combination of vibostolimab and pembrolizumab with chemotherapy to atezolizumab with chemotherapy, failed to meet the primary endpoint of overall survival and demonstrated a higher rate of adverse events.
The clinical trial enrolled 460 patients to evaluate the efficacy and safety of the vibostolimab and pembrolizumab combination, but the pre-planned analysis indicated that the trial would not achieve its primary goal. In addition to futility, the combination was associated with increased adverse and immune-related events compared to the control group.
As a result of the trial's discontinuation, Merck is advising study investigators to cease treatment with the investigational combination and offer patients the option to be treated with atezolizumab. The company plans to share the findings with the scientific community.
Despite the setback, Merck remains committed to advancing its extensive clinical development program in lung cancer, which includes multiple registration-enabling studies. The company is also collaborating with Daiichi Sankyo on the IDeate-Lung02 Phase 3 trial, evaluating investigational ifinatamab deruxtecan (I-DXd) in patients with relapsed SCLC, and expanding its agreement to include MK-6070, a delta-like ligand 3 (DLL3) targeting T-cell engager.
Small cell lung cancer is a particularly challenging disease to treat, with a low five-year survival rate and limited progress in treatment options. Merck's ongoing research efforts aim to improve patient outcomes through earlier disease detection and novel treatment combinations.
The termination of the KeyVibe-008 trial is a reminder of the complexities and uncertainties inherent in drug development, particularly in the field of oncology. Merck's decision to halt the trial was based on a press release statement, which serves as the source of this report.
