Cabozantinib, sold under the brand names Cometriq and Cabometyx among others, is an anti-cancer medication used to treat medullary thyroid cancer, renal cell carcinoma, and hepatocellular carcinoma. [9] [10] It is a small molecule inhibitor of the tyrosine kinases c-Met and VEGFR2, and also inhibits AXL and RET. [8] [7] It was discovered and developed by Exelixis Inc.
In November 2012, cabozantinib in its capsule formulation was approved by the US Food and Drug Administration (FDA) under the name Cometriq for treating people with medullary thyroid cancer. [13] [14] The capsule form was approved in the European Union for the same purpose in 2014. [11] In April 2016, the FDA granted approval for marketing the tablet formulation (Cabometyx) as a second line treatment for kidney cancer [15] [16] and the same was approved in the European Union in September of that year. [12] The brands Cometriq and Cabometyx have different formulations and are not interchangeable. [17]
Cabozantinib is used in two forms. A capsule form (Cometriq) is used to treat medullary thyroid cancer [10] [8] and a tablet form (Cabometyx) is used to treat renal cell carcinoma, hepatocellular carcinoma, and differentiated thyroid carcinoma. [9] [7] [18]
Cabozantinib has not been tested in pregnant women; it causes harm to fetuses in rodents. Pregnant women should not take this drug, and women should not become pregnant while taking it. It is not known if cabozantinib is excreted in breast milk. [8] [7]
In the US, the capsule formulation (Cometriq) carries a black box warning of the risk of holes forming in the stomach or intestines as well as formation of fistulas (tunnels between the GI tract and the skin). [10] The black box also warns against the risk of uncontrolled bleeding. [10] The tablet formulation (Cabometyx) warns of these effects as well. [9] [7]
The labels also warn of the risk of clots forming and causing heart attacks or strokes, high blood pressure including hypertensive crisis, osteonecrosis of the jaw, severe diarrhea, skin sloughing off the palms and soles, a syndrome with headaches, confusion, loss of vision, and seizures, and protein appearing in urine. [10] [9] [8] [7]
Very common adverse effects (greater than 10% of people) include decreased appetite; low calcium, potassium, phosphate, and magnesium levels; high bilirubin levels; distorted sense of taste, headache, and dizziness; high blood pressure; distorted sense of hearing, earaches and sore throat; diarrhea, nausea, constipation, vomiting, stomach pain and upset stomach, and inflammation of the mouth and lips and a burning sensation in the mouth; skin sloughing off the palms and soles, hair color changes and hair loss, rash, dry skin, and red skin; joint pain and muscle spasms; fatigue and weakness; weight loss, elevated transaminases, higher cholesterol levels, and loss of red and white blood cells. [7]
Common adverse effects (between 1% and 10% of people) include abscesses (inside the body, on the skin, and in teeth skin), pneumonia, inflamed hair follicles, fungal infections, low thyroid levels, dehydration, loss of albumin, anxiety, depression, and confusion, peripheral neuropathy, tingling, and tremor, tinnitus, atrial fibrillation, low blood pressure, blocked veins, paleness, chills, fistulas forming in the trachea and esophagus, blood clots in the lungs, and bleeding in the respiratory tract, GI perforation, bleeding in the stomach and intestines, pancreatitis, hemorrhoids, anal fissure, anal inflammation, gallstones, hard skin growths, acne, blisters, abnormal hair growth, loss of skin color and skin flaking, chest pain, blood or protein in urine, wounds that don't heal well, and facial swelling. [7]
Cabozantinib is a substrate of CYP3A4 and multidrug resistance-associated protein 2; drugs that inhibit these enzymes will increase the half-life of cabozantinib and potentially increase its adverse effects; drugs that activate them may cause cabozantinib to be less effective. [7]
Cabozantinib inhibits the following receptor tyrosine kinases: MET (hepatocyte growth factor receptor protein) and VEGFR, RET, GAS6 receptor (AXL), KIT), and Fms-like tyrosine kinase-3 (FLT3). [7] [19]
Cabozantinib was granted orphan drug status by the US Food and Drug Administration (FDA) in November 2010, [20] and in February 2017. [21]
Exelixis filed a new drug application with the FDA in 2012, [22] and in November 2012, cabozantinib in its capsule formulation was granted marketing approval by the FDA under the name Cometriq for treating people with medullary thyroid cancer. [13] [14] The capsule form was approved in the European Union for the same purpose in 2014. [11]
In March 2016, Exelixis licensed to Ipsen worldwide rights (outside the US, Canada, and Japan) to market cabozantinib. [23]
In April 2016, the FDA granted approval for marketing the tablet formulation as a second line treatment for kidney cancer [15] [16] and the same was approved in the European Union in September of that year. [12]
In December 2017, the FDA granted approval to cabozantinib (Cabometyx, Exelixis, Inc.) for the treatment of people with advanced renal cell carcinoma (RCC). [17] The approval was based on data from CABOSUN (NCT01835158), a randomized, open-label phase II multicenter study in 157 participants with intermediate and poor-risk previously untreated RCC. [17]
In January 2019, the FDA approved cabozantinib (Cabometyx, Exelixis, Inc.) for people with hepatocellular carcinoma who have been previously treated with sorafenib. [24] The approval was based on CELESTIAL (NCT01908426), a randomized (2:1), double-blind, placebo-controlled, multicenter trial in participants with hepatocellular carcinoma who had previously received sorafenib and had Child Pugh Class A liver impairment.
Cabozantinib is being researched [25] for efficacy as a treatment for renal cell carcinoma (RCC), hepatocellular carcinoma (HCC), cervical cancer, colorectal cancer (CRC), urothelial cancer, prostate cancer, gastric and gastroesophageal cancer, bladder cancer, melanoma, merkel cell carcinoma, brain cancers (including glioblastoma multiforme and anaplastic astrocytoma), non-small cell lung cancer (NSCLC), adrenocortical carcinoma, various sarcomas, head and neck squamous cell carcinomas (HNSCC), breast cancer, endometrial cancer, neuroendocrine cancers, and neurofibromatosis type 1. [26]

Onyx was founded in 1992 by Kevin J. Kinsella and Frank McCormick Ph.D., FRS. McCormick served as the chief scientific officer until 1998, while Kinsella was the firm's chairman. In 2009, the company acquired Proteolix, Inc., a private biotechnology company, for $276 million in cash plus additional milestone payments. In January 2012, the company was named "the top biotechnology takeover target in 2012" through an industry survey. Onyx president and chief executive officer (CEO) N. Anthony Coles had said that Onyx liked its prospects as an independent company and was focused on bringing new therapies to patients. However, at the end of August 2013, Amgen announced it was acquiring Onyx in an agreed $10.4 billion deal.
Ibrutinib, sold under the brand name Imbruvica among others, is a small molecule drug that inhibits B-cell proliferation and survival by irreversibly binding the protein Bruton's tyrosine kinase (BTK). Blocking BTK inhibits the B-cell receptor pathway, which is often aberrantly active in B cell cancers. Ibrutinib is therefore used to treat such cancers, including mantle cell lymphoma, chronic lymphocytic leukemia, and Waldenström's macroglobulinemia. Ibrutinib also binds to C-terminal Src Kinases. These are off-target receptors for the BTK inhibitor. Ibrutinib binds to these receptors and inhibits the kinase from promoting cell differentiation and growth. This leads to many different side effects like left atrial enlargement and atrial fibrillation during the treatment of Chronic Lymphocytic Leukemia.
Nivolumab, sold under the brand name Opdivo, is an anti-cancer medication used to treat a number of types of cancer.
