Tafinlar (dabrafenib) is a medication used to treat certain types of cancer. It works by blocking a specific protein that can cause cancer cells to grow. This medication is being studied for long-term use in children who have certain types of cancer.

Mekinist (trametinib) is another cancer medication that works by targeting a different protein involved in cancer cell growth. Like Tafinlar, it is being studied for long-term treatment in pediatric patients with cancer.

The trial also studies the combination of Tafinlar and Mekinist together, as these medications can work in partnership to fight cancer cells through different mechanisms. This combination approach may provide better results than using either medication alone.

Cancer with V600 mutation – A specific type of cancer characterized by a mutation in the BRAF gene at position V600. This genetic alteration causes cells to grow and divide uncontrollably. The mutation can occur in various types of cancer, particularly affecting children and adolescents. The condition involves changes in normal cell growth patterns, leading to the formation of tumors. The disease progresses when mutated cells continue to multiply and potentially spread to other parts of the body.

Rare Cancer – A form of cancer that affects a limited number of people compared to more common cancer types. This condition occurs in a small percentage of the population, making it less frequently encountered in medical practice. The disease develops when specific cell types in the body begin to grow abnormally. These cancers can appear in various parts of the body and may have unique growth patterns.
