CABOZANTINIB



COMETRIQ is indicated for the treatment of patients with progressive, metastatic medullary thyroid cancer (MTC).
Learn More COMETRIQ (cabozantinib) -- NOW AVAILABLE
COMETRIQ inhibits the activity of tyrosine kinases including RET, MET, and VEGFRs. 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 was approved based on a pivotal trial in metastatic MTC patients (N=330) who were required to have radiographic evidence of actively progressive disease within 14 months prior to study entry.
Significantly prolonged progression-free survival (PFS) vs placebo (HR=0.28; 95% CI: 0.19, 0.40; P<0.0001)
— Median PFS was 11.2 months with COMETRIQ vs 4.0 months with placebo
Objective response rate (ORR) was 27% with COMETRIQ vs 0% with placebo (P<0.0001)
— Median duration of tumor response was 14.7 months (95% CI: 11.1, 19.3)
Adverse reactions occurring in ≥25% of patients treated with COMETRIQ and more frequently than with placebo (≥5% between-arm difference) in order of decreasing frequency were: 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%) were increased AST, increased ALT, lymphopenia, increased alkaline phosphatase, hypocalcemia, neutropenia, thrombocytopenia, hypophosphatemia, and hyperbilirubinemia.

IMPORTANT SAFETY INFORMATION
BOXED WARNING: PERFORATIONS AND FISTULAS, and HEMORRHAGE
See full prescribing information for complete boxed warning.
Perforations and Fistulas: Gastrointestinal perforations occurred in 3% and fistula formation in 1% of COMETRIQ-treated patients. Discontinue COMETRIQ in patients with perforation or fistula.
Hemorrhage: Severe, sometimes fatal, hemorrhage including hemoptysis and gastrointestinal hemorrhage occurred in 3% of COMETRIQ-treated patients. Monitor patients for signs and symptoms of bleeding. Do not administer COMETRIQ to patients with severe hemorrhage.
ADDITIONAL IMPORTANT SAFETY INFORMATION
Gastrointestinal (GI) perforations (3%) and GI fistulas (1%), all serious, were reported with COMETRIQ, including 1 (<1%) fatal GI fistula. Non-GI fistulas including tracheal/esophageal were reported (4%), including 2 (1%) fatal events. Monitor patients for symptoms of perforations and fistulas. Discontinue COMETRIQ in patients who experience a perforation or a fistula.
Serious and sometimes fatal hemorrhage occurred with COMETRIQ. The incidence of Grade ≥3 hemorrhagic events was higher with COMETRIQ (3%) than with placebo (1%). Do not administer COMETRIQ to patients with a recent history of hemorrhage or hemoptysis.
Increased incidence of thrombotic events (venous thromboembolism: 6% vs 3%; arterial thromboembolism: 2% vs 0%) was reported with COMETRIQ vs placebo, respectively. Discontinue COMETRIQ in patients who develop an acute myocardial infarction or any other clinically significant arterial thromboembolic complication.
Wound complications have been reported with COMETRIQ. Stop treatment with COMETRIQ ≥28 days prior to scheduled surgery. Resume COMETRIQ therapy after surgery based on clinical judgment of adequate wound healing. Withhold COMETRIQ in patients with dehiscence or wound healing complications requiring medical intervention.
Increased incidence of treatment-emergent hypertension, stage 1 or 2 (modified JNC criteria), was identified with COMETRIQ (61% vs 30% with placebo). Monitor blood pressure prior to initiation and regularly during COMETRIQ treatment. Withhold COMETRIQ for hypertension that is not adequately controlled with medical management; when controlled, resume COMETRIQ at a reduced dose. Discontinue COMETRIQ for severe hypertension that cannot be controlled with anti-hypertensive therapy.
Osteonecrosis of the jaw (ONJ) occurred with COMETRIQ (1%). ONJ can manifest as jaw pain, osteomyelitis, osteitis, bone erosion, tooth or periodontal infection, toothache, gingival ulceration or erosion, persistent jaw pain or slow healing of the mouth or jaw after dental surgery. Perform an oral examination prior to initiation of COMETRIQ and periodically during therapy. Advise patients regarding good oral hygiene practices. For invasive dental procedures, withhold COMETRIQ treatment for ≥28 days prior to scheduled surgery, if possible.
Palmar-plantar erythrodysesthesia syndrome (PPES) occurred (50%) with COMETRIQ and was severe (Grade ≥3) in 13% of patients. Withhold COMETRIQ in patients who develop intolerable Grade 2 PPES or Grade 3-4 PPES until improvement to Grade 1; resume COMETRIQ at a reduced dose.
Proteinuria was observed in 4 (2%) patients receiving COMETRIQ, including 1 with nephrotic syndrome, compared with 0 patients receiving placebo. Monitor urine protein regularly during COMETRIQ treatment. Discontinue COMETRIQ in patients who develop nephrotic syndrome.
Reversible posterior leukoencephalopathy syndrome (RPLS) occurred in 1 (<1%) patient. Perform an evaluation for RPLS in any patient presenting with seizures, headache, visual disturbances, confusion, or altered mental function. Discontinue COMETRIQ in patients who develop RPLS.
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. If this drug is used during pregnancy, or if the patient becomes pregnant during therapy, the patient should be apprised of the potential hazard to the fetus.
The COMETRIQ dose was reduced in 79% of patients vs 9% for placebo.
