Interactions

7 DRUG INTERACTIONS Strong CYP3A4 inhibitors: Reduce the CABOMETYX dosage if coadministration cannot be avoided. ( 2.4 , 7.1 ) Strong or moderate CYP3A4 inducers: Increase the CABOMETYX dosage if coadministration cannot be avoided. ( 2.5 , 7.1 ) 7.1 Effects of Other Drugs on CABOMETYX Strong CYP3A4 Inhibitors Coadministration of a cabozantinib capsule formulation with a strong CYP3A4 inhibitor increased the exposure of cabozantinib, which may increase the risk of exposure-related adverse reactions [see Clinical Pharmacology (12.3) ] . Avoid coadministration of CABOMETYX with strong CYP3A4 inhibitors. Reduce the dosage of CABOMETYX if coadministration with strong CYP3A4 inhibitors cannot be avoided [see Dosage and Administration (2.4) ] .

Warnings

5 WARNINGS AND PRECAUTIONS Hemorrhage: Do not administer CABOMETYX if recent history of hemorrhage. ( 5.1 ) Perforations and Fistulas: Monitor for symptoms. Discontinue CABOMETYX for Grade 4 fistula or perforation. ( 5.2 ) Thromboembolic Events: Discontinue CABOMETYX for myocardial infarction or serious venous or arterial thromboembolic events. ( 5.3 ) Hypertension and Hypertensive Crisis: Monitor blood pressure regularly. Interrupt for hypertension that is not adequately controlled with anti-hypertensive therapy. Discontinue CABOMETYX for hypertensive crisis or severe hypertension that cannot be controlled with anti-hypertensive therapy. ( 5.4 ) Cardiac Failure: Monitor patients for signs and symptoms of cardiac failure throughout treatment. ( 5.5 ) Diarrhea: May be severe. 4 CONTRAINDICATIONS None. None ( 4 )

Pregnancy

8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1) ] , CABOMETYX can cause fetal harm when administered to a pregnant woman. There are no available data in pregnant women to inform the drug-associated risk. In animal developmental and reproductive toxicology studies administration of cabozantinib to pregnant rats and rabbits during organogenesis resulted in embryofetal lethality and structural anomalies at exposures that were below those occurring clinically at the recommended dose (see Data ) .
