Zelboraf® & Cotellic® combination therapy
(vemurafenib) & (cobimetinib)
Pronounced Zel-bor-af & Co-tell-ic
Zelboraf, also known as vemurafenib, is a targeted therapy used to treat a type of skin cancer called melanoma. It is registered by Medsafe for the treatment of adult patients with melanoma which:
- Has spread to other parts of the body (metastatic) or cannot be removed by surgery, and
- Has a certain type of abnormal gene (the BRAF gene).
Cotellic, also known as cobimetinib, is a different type of targeted therapy for the treatment of melanoma, which is used in combination with Zelboraf. The combination of Zelboraf and Cotellic has been shown to work better than Zelboraf alone.
Ask your doctor if Zelboraf and Cotellic are right for you.
How Zelboraf and Cotellic combination treatment works
How Zelboraf works
BRAF is a protein that tells cells when to grow and divide. When it works properly, cells grow and divide at a normal rate.
However, in about 50% of melanoma cases the BRAF protein is faulty. The signals that normally switch the protein off do not work, causing the cells to multiply too quickly and create tumours. It’s like a light circuit in your home that has been built with a faulty switch — no matter how many times you click it up and down, the light remains on.
Zelboraf targets the faulty BRAF protein to help stop the melanoma cells from growing and dividing.
How Cotellic works
The MEK pathway is another mechanism that manages cell production in a healthy body. If it stops working properly cell growth may become uncontrolled, resulting in the development and growth of tumours.
Cotellic is a MEK inhibitor, which means it works by stopping MEK1 and/or MEK2 proteins from overworking. It is not approved to be used on its own — only in combination with Zelboraf.
How Zelboraf and Cotellic combination therapy works
Combination therapy turns off two switches in the circuit and therefore blocks the stimulus that encourages the growth of melanoma.
