This clinical trial is focused on studying the treatment of advanced solid tumors, which are cancers that have spread beyond their original location and are difficult to treat. The study involves two treatments: MK-1088, a medication taken as a tablet, and pembrolizumab, also known by its brand name KEYTRUDA, which is given as an infusion through a vein. Pembrolizumab is a type of protein-based medication that helps the immune system fight cancer cells.
The purpose of the study is to evaluate the safety and tolerability of MK-1088 both on its own and in combination with pembrolizumab. Participants will receive either MK-1088 alone or together with pembrolizumab to determine the best dose that can be safely given. The study will monitor participants for any side effects and how well they tolerate the treatments. The trial will also look at how the body processes MK-1088 by measuring its levels in the blood over time.
Participants in the study will have a confirmed diagnosis of advanced solid tumors and may have already tried other treatments. The study will last for a period of time during which participants will receive the treatments and be closely monitored by the research team. The goal is to find a safe and effective dose of MK-1088, both alone and in combination with pembrolizumab, to help treat advanced solid tumors.
