Study Summary

This trial is testing a new cancer drug to see if it is safe and effective.

Who is the study for?
Adults with advanced or metastatic solid tumors who have tried all other treatments or can't tolerate them are eligible. They must have measurable disease, normal heart function, and adequate organ function. Participants need to provide a tumor sample for analysis and agree to use contraception. Excluded are those with certain lung conditions, recent transplants, active infections including HIV/HBV/HCV, uncontrolled diseases or conditions that could affect the trial's outcome.Check my eligibility
What is being tested?
The study is testing MK-1484 alone and combined with Pembrolizumab in patients with advanced solid tumors. It aims to find out how safe these treatments are and determine the best dose for Phase 2 trials.See study design
What are the potential side effects?
While not specified here, common side effects of cancer immunotherapy like MK-1484 and Pembrolizumab may include fatigue, skin reactions, inflammation in organs such as lungs (pneumonitis), liver problems, hormonal changes affecting glands like thyroid; also possible immune system reactions.
