Cabozantinib is a cancer medicine that interferes with the growth and spread of cancer cells in the body. It is used to treat a certain type of thyroid cancer (medullary thyroid cancer) that has spread to other parts of the body. Cabozantinib is also used to treat advanced kidney cancer (advanced renal cell carcinoma).
Cabozantinib: A Multi-Targeted Cancer Medication
Cabozantinib, sold under brand names like Cabometyx and Cometriq (discontinued), is a prescription medication classified as a multi-targeted tyrosine kinase inhibitor (TKI). Here's a summary of its key aspects:
Function:
- Primarily used to treat various cancers, including:
- Metastatic medullary thyroid cancer (progressive, advanced form) in adults and children 12 years and older who are ineligible for radioactive iodine treatment or whose cancer worsened after VEGFR-targeted therapy.
- Advanced renal cell carcinoma (kidney cancer) in adults.
- Hepatocellular carcinoma (liver cancer) in adults who have already been treated with sorafenib (another medication).
- Works by blocking the activity of several tyrosine kinases. These enzymes play a crucial role in the growth, division, and survival of cancer cells. By inhibiting these enzymes, cabozantinib aims to:
- Slow down or stop the growth and spread of cancer cells.
- Reduce blood vessel formation around tumors, which can hinder their ability to access nutrients and grow.
Mechanism of Action:
- As mentioned earlier, cabozantinib acts as a multi-targeted TKI. This means it can target and inhibit multiple tyrosine kinases simultaneously, potentially offering a broader range of action compared to TKIs targeting only one specific enzyme.
Formulations:
- Available as capsules taken orally.
Important to Note:
- Cabozantinib can cause various side effects, including:
- Diarrhea
- Fatigue
- Nausea and vomiting
- High blood pressure
- Hand-foot syndrome (rash and swelling on the palms of hands and soles of feet)
- Liver problems
- Cabozantinib is a potent medication and should only be used under the supervision of a healthcare professional. It's crucial to disclose your medical history and any medications you are taking before starting cabozantinib treatment.
- Pregnancy and breastfeeding: Cabozantinib can be harmful to the developing fetus and is not recommended for use during pregnancy or breastfeeding.
Additional Points:
- Cabozantinib has received approval from the US Food and Drug Administration (FDA) for the aforementioned uses.

Cabozanitinib L-Malate
Here's a breakdown of cabozantinib:
- Brand names: Cabometyx, Cometriq (discontinued)
- Function: A multi-targeted tyrosine kinase inhibitor (TKI) used to treat several types of cancer, including:
- Metastatic medullary thyroid cancer (progressive, advanced form) in adults and children 12 years and older who cannot receive radioactive iodine and whose cancer worsened after VEGFR-targeted therapy.
- Advanced renal cell carcinoma (kidney cancer) in adults.
- Hepatocellular carcinoma (liver cancer) in adults who have already been treated with sorafenib (another medication).
- Mechanism of action: Works by blocking the activity of several tyrosine kinases, which are enzymes involved in the growth and survival of cancer cells. By inhibiting these enzymes, cabozantinib slows down or stops the growth and spread of cancer cells.
- Formulations: Available as capsules taken orally.
About L-Malate Salt:
- The L-malate part refers to a specific salt form of cabozantinib.
- Salts are formed when an acid and a base react. In this case, cabozantinib (a weakly basic molecule) combines with L-malic acid (an organic acid) to form the L-malate salt.
- This salt form is often used to improve the pharmaceutical properties of the drug, such as absorption, stability, or solubility.
Therefore, when referring to the medication, it's more accurate to simply use "cabozantinib" instead of "Cabozanitinib L-Malate".
