Is Cotellic FDA-approved?

Accepted Answer

Yes, Cotellic (Cobimetinib) is approved by the U.S. Food and Drug Administration (FDA) for use in combination with vemurafenib to treat patients with unresectable or metastatic melanoma with specific BRAF V600 mutations. It is also approved as a single agent for certain histiocytic neoplasms. The FDA evaluated its safety and effectiveness through clinical studies.

Question 3

Why Is Cotellic Taken with Vemurafenib for Melanoma?

Accepted Answer

Cotellic is used together with vemurafenib to target two different steps in the same cancer growth pathway. This medicine blocks MEK proteins, while vemurafenib blocks the BRAF protein. Using both medications together helps slow tumor growth more effectively and increases cancer cell death compared to using either drug alone.
