What is Cometriq?
Cometriq is a kinase inhibitor that interferes with the growth of some cancer cells.
Cometriq is a prescription medicine used to treat thyroid cancer that has spread to other parts of the body.
The Cabometyx brand of cabozantinib is used to treat advanced kidney cancer and liver cancer in people who have been previously treated with sorafenib (Nexavar).
Cometriq may cause a perforation (a hole or tear) or a fistula (an abnormal passageway) within your stomach or intestines. Cometriq can also increase your risk of serious bleeding.
Call your doctor if you have: severe stomach pain, choking or gagging when you eat or drink, unusual bleeding, bloody or tarry stools, heavy menstrual bleeding, or if you cough up blood.

Cabometyx (cabozantinib) is taken until disease progression - the cancer starts to get worse - or you can no longer tolerate therapy because of the side effects or adverse reactions.
In clinical trials the median amount of time patients took Cabometyx for before their cancer progressed was:
- METEOR trial - 7.4 months (95% CI 5.6, 9.1)
- CABOSUN trial - 8.6 months (95% CI 6.8, 14.0)
- CELESTIAL trial - 5.2 months (95% CI 4.0, 5.5)
- CHECKMATE-9ER trial - 16.6 months (95% CI 12.5, 24.9)
- COSMIC-311 - 11 months (95% CI 7.4, 13.8)
How successful Cabometyx (cabozantinib) is can be measured by how:
- Long patients take the treatment for
- Long patients survive for without their cancer getting worse (progression-free survival)
- Many months patients remain alive for while taking the treatment
- Many patients respond to the drug
Cabometyx (cabozantinib) does not cure advanced renal cell carcinoma (kidney cancer), hepatocellular carcinoma (liver cancer) or advanced or metastatic differentiated thyroid cancer. Instead it helps to slow the progression of cancer, potentially enabling patients to live longer. Continue reading
