About Cabozantinib

Cabozantinib inhibits the activity of tyrosine kinases including MET, VEGFRs and RET. These receptor tyrosine kinases are involved in both normal cellular function and in pathologic processes such as oncogenesis, metastasis, tumor angiogenesis, and maintenance of the tumor microenvironment.

COMETRIQ® (cabozantinib) is currently approved by the U.S. Food and Drug Administration for the treatment of progressive, metastatic medullary thyroid cancer (MTC).

The European Commission granted COMETRIQ conditional approval for the treatment of adult patients with progressive, unresectable locally advanced or metastatic MTC. Similar to another drug approved in this setting, the approved indication states that for patients in whom Rearranged during Transfection (RET) mutation status is not known or is negative, a possible lower benefit should be taken into account before individual treatment decisions.

Important Safety Information, including Boxed WARNINGS


  • Serious and sometimes fatal gastrointestinal perforations and fistulas occur in COMETRIQ-treated patients.
  • Severe and sometimes fatal hemorrhage occurs in COMETRIQ-treated patients.
  • COMETRIQ treatment results in an increase in thrombotic events, such as heart attacks.
  • Wound complications have been reported with COMETRIQ.
  • COMETRIQ treatment results in an increase in hypertension.
  • Osteonecrosis of the jaw has been observed in COMETRIQ-treated patients.
  • Palmar-Plantar Erythrodysesthesia Syndrome (PPES) occurs in patients treated with COMETRIQ.
  • The kidneys can be adversely affected by COMETRIQ. Proteinuria and nephrotic syndrome have been reported in patients receiving COMETRIQ.
  • Reversible Posterior Leukoencephalopathy Syndrome has been observed with COMETRIQ.
  • Avoid administration of COMETRIQ with agents that are strong CYP3A4 inducers or inhibitors.
  • COMETRIQ is not recommended for use in patients with moderate or severe hepatic impairment.
  • COMETRIQ can cause fetal harm when administered to a pregnant woman.

Adverse Reactions – The most commonly reported adverse drug reactions (≥25%) are diarrhea, stomatitis, palmar-plantar erythrodysesthesia syndrome (PPES), decreased weight, decreased appetite, nausea, fatigue, oral pain, hair color changes, dysgeusia, hypertension, abdominal pain, and constipation. The most common laboratory abnormalities (≥25%) are increased AST, increased ALT, lymphopenia, increased alkaline phosphatase, hypocalcemia, neutropenia, thrombocytopenia, hypophosphatemia, and hyperbilirubinemia.

About Cobimetinib

Cobimetinib (formerly GDC-0973/XL518) is an inhibitor of MEK, a serine/threonine kinase that is a component of the RAS/RAF/MEK/ERK pathway. This pathway mediates signaling downstream of growth factor receptors, and is prominently activated in a wide variety of human tumors. In preclinical studies, oral dosing of cobimetinib resulted in sustained inhibition of MEK in RAS or BRAF mutant tumor models. Cobimetinib is being developed by Roche and Genentech, a member of the Roche Group, under a collaboration with Exelixis.
