PART 1: The primary objective of this study is to identify the maximum tolerated dose
(MTD) of MK-3795, formerly called PT2385 and/or the recommended Phase 2 dose (RP2D) of
MK-3795 in patients with advanced clear cell renal cell carcinoma (ccRCC).
PART 2: The primary objective of this study is to identify the MTD of MK-3795 up to the
RP2D, in combination with nivolumab, in patients with advanced ccRCC.As of Amendment 09
(29 Mar 2024), participants with advanced ccRCC will transition from MK-3795 to
belzutifan (MK-6482) in combination with nivolumab or belzutifan alone.
PART 3: The primary objective of this study is to identify the MTD of MK-3795 up to the
RP2D, in combination with cabozantinib tablets, in patients with advanced ccRCC.
Study sponsor and potential other locations can be found on ClinicalTrials.gov for NCT02293980.
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.
