The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic and pharmacodynamic profiles, and preliminary efficacy of belzutifan as monotherapy followed by belzutifan+lenvatinib combination therapy, as well as belzutifan combined with lenvatinib and pembrolizumab in China participants with advanced renal cell carcinoma.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Merck & Co (MRK) is the sponsoring company for this trial. BiotechSign currently grades this company F (35/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
