This clinical trial is focused on studying treatments for people with advanced solid tumors, which are types of cancer that have spread and are difficult to treat. The study involves two treatments: BMS-986449, a new medication taken as a capsule, and nivolumab, also known by its code name BMS936558, which is given through an infusion into a vein. The purpose of the study is to understand how safe and tolerable these treatments are when used alone or together in patients with advanced cancer.
Participants in the study will receive either BMS-986449 by itself or in combination with nivolumab. The study will monitor how the body responds to these treatments and any side effects that may occur. Some participants may receive a placebo, which is a substance with no active medication, to compare the effects of the actual treatments. The study will help researchers learn more about how these treatments work in the body and their potential benefits for people with advanced cancer.
The trial will take place over a period of time, during which participants will have regular check-ups and tests to monitor their health and the effects of the treatments. The information gathered from this study will contribute to understanding the potential of BMS-986449 and nivolumab as treatment options for advanced solid tumors, providing valuable insights for future cancer therapies.
