This clinical trial is focused on studying a type of cancer known as lung cancer, specifically in patients with a certain genetic change called the KRAS G12C mutation. The study will explore the effects of a new treatment called RMC-6291, which will be used in combination with another medication called pembrolizumab. Pembrolizumab is a type of medicine that helps the immune system fight cancer. In some cases, the treatment may also include chemotherapy, which is a common cancer treatment that uses drugs to kill cancer cells.
The purpose of this study is to evaluate how safe and tolerable the combination of these treatments is for patients with advanced solid tumors that have the KRAS G12C mutation. The study will involve patients who have previously received cancer treatment and have at least one tumor that can be measured. Participants will receive the treatment over a period of time, and their health will be closely monitored to observe any side effects and how their body responds to the treatment.
Throughout the study, researchers will collect information on the levels of RMC-6291 in the blood and assess the overall response of the tumors to the treatment. The study aims to provide valuable insights into the potential benefits and risks of using RMC-6291 in combination with pembrolizumab and chemotherapy for treating lung cancer with the KRAS G12C mutation.
