A Phase Ib Study to Evaluate the Safety and Tolerability of MK-8353 in Combination With Pembrolizumab in Patients With Advanced Malignancies
This study will evaluate the safety, tolerability and preliminary efficacy of MK-8353 when
administered in combination with pembrolizumab (MK-3475). There are two parts in this study:
Part 1 will be dose escalation and confirmation, and Part 2 will be a cohort expansion. In
Part 1, the recommended phase II dose (RP2D) of MK-8353 in combination with a fixed dose of
pembrolizumab in participants with advanced malignancies will be identified and confirmed.
Participants will be initially enrolled to receive MK-8353 at 350 mg twice a day (BID) in
combination with pembrolizumab at a fixed dose of 200 mg on Day 1 of each 3-week cycle (Q3W)
for up to 24 months of treatment. In Part 2, participants with advanced colorectal cancer
(CRC) who received at least one and up to five prior lines of therapy will be enrolled at
the RP2D in the expansion cohort to further evaluate safety and efficacy.
