This clinical trial is focused on studying the effectiveness and safety of different combinations of treatments for patients with a type of skin cancer called melanoma. Specifically, it involves patients who have previously been treated for melanoma that cannot be surgically removed or has spread to other parts of the body. The study is looking at cases where the melanoma has specific genetic changes known as BRAFV600 or NRAS mutations. The treatments being tested in this study include combinations of medications such as ribociclib (also known as LEE011), trametinib dimethyl sulfoxide (TMT212), naporafenib (LXH254), and rineterkib (LTT462). These medications are taken orally in the form of tablets or capsules.
The purpose of the study is to evaluate how well these treatment combinations work in shrinking the tumors and to assess their safety. Participants in the study will receive one of the treatment combinations or a placebo. The study will monitor the response of the cancer to the treatment and any side effects that may occur. The study is divided into two parts and will involve regular check-ups and assessments to track the progress of the treatment.
Throughout the study, participants will undergo various tests and evaluations to measure the effectiveness of the treatment. This includes imaging tests to see how the cancer is responding and regular health check-ups to monitor for any side effects. The study aims to provide valuable information on the potential benefits and risks of these treatment combinations for patients with advanced melanoma.
