This study is testing a combination of three drugs - dabrafenib, trametinib, and hydroxychloroquine - on brain tumors in children and young adults. These tumors have a specific genetic change called a BRAF aberration, which means there's a problem in the BRAF gene that can make tumors grow. The drugs work by stopping tumor cells from growing or dividing. The study is split into two parts: Phase I will find the best dose, and Phase II will see how well the drugs work. Participants will take the drugs for up to 2 years, as long as the drugs are helping and side effects are manageable. Phase I will help determine the safest doses for Phase II, where patients will continue receiving the drug combination. People who want to join must have had a certain type of cancer treatment before and meet specific health requirements.
- The study lasts up to 2 years, with treatments given daily in 28-day cycles.
- Participants will need to visit the study site for tests and check-ups.
- Eligibility includes having specific genetic changes and prior specific cancer treatments.
