Description

PART 1: This is a Phase 1, multiple-dose, dose-escalation trial of MK-3795, where patients with advanced ccRCC will be assigned to sequential dose cohorts. Patient safety will be monitored with frequent physical examinations, vital sign measurements, electrocardiograms (ECGs), and hematology and chemistry laboratory studies, and by recording all adverse events (AEs). Blood will be obtained for analysis of the concentration of MK-3795 and to assess biomarkers.

PART 2: This is a Phase 1 trial of MK-3795 in combination with nivolumab, where patients with advanced ccRCC will be assigned to dose cohorts. Patient safety will be monitored with frequent physical examinations, vital sign measurements, ECGs, and hematology and chemistry laboratory studies, and by recording all AEs. Blood will be obtained for analysis of the concentration of MK-3795 and to assess biomarkers. As of Amendment 09 (29 Mar 2024), participants with advanced ccRCC will transition from MK-3795 to belzutifan in combination with nivolumab or belzutifan alone.

PART 3: This is a Phase 1 trial of MK-3795 in combination with cabozantinib tablets, where patients with advanced ccRCC will be assigned to dose cohorts. Patient safety will be monitored with frequent physical examinations, vital sign measurements, ECGs, and hematology and chemistry laboratory studies, and by recording all AEs. Blood will be obtained for analysis of the concentration of MK-3795 and cabozantinb and to assess biomarkers.
