Trametinib

How does Trametinib work?

Trametinib is a MEK inhibitor that blocks the MEK1 and MEK2 proteins, preventing cancer cells from growing and spreading. This helps slow down tumor progression in BRAF-mutant cancers. It is particularly effective when combined with dabrafenib, which targets the BRAF protein.

Is Trametinib effective?

Yes, clinical trials show that trametinib, especially when combined with dabrafenib, significantly improves progression-free survival in patients with BRAF-mutant melanoma and lung cancer. Studies indicate that it reduces tumor growth and extends patient survival compared to chemotherapy alone.

What is Trametinib?
