Cabometyx Dosage/Direction for Use

Therapy with CABOMETYX should be initiated by a physician experienced in the administration of anticancer medicinal products.
Posology: CABOMETYX tablets and cabozantinib capsules are not bioequivalent and should not be used interchangeably (see Pharmacology: Pharmacokinetics under Actions).
CABOMETYX as monotherapy: For RCC, HCC and DTC, the recommended dose of CABOMETYX is 60 mg once daily.
Treatment should continue until the patient is no longer clinically benefiting from therapy or until unacceptable toxicity occurs.
CABOMETYX in combination with nivolumab in first-line advanced RCC: The recommended dose of CABOMETYX is 40 mg once daily in combination with nivolumab administered intravenously at either 240 mg every 2 weeks or 480 mg every 4 weeks.
The treatment should continue until disease progression or unacceptable toxicity. Nivolumab should be continued until disease progression, unacceptable toxicity, or up to 24 months in patients without disease progression (see the Prescribing Information (PI) for posology of nivolumab).
Treatment modification: Management of suspected adverse drug reactions may require temporary treatment interruption and/or dose reduction (see Table 6). When dose reduction is necessary in monotherapy, it is recommended to reduce to 40 mg daily, and then to 20 mg daily.
When CABOMETYX is administered in combination with nivolumab, it is recommended to reduce the dose to 20 mg of CABOMETYX once daily, and then to 20 mg every other day (refer to the nivolumab PI for recommended treatment modification for nivolumab).
Dose interruptions are recommended for management of CTCAE Grade 3 or greater toxicities or intolerable Grade 2 toxicities. Dose reductions are recommended for events that, if persistent, could become serious or intolerable.
If a patient misses a dose, the missed dose should not be taken if it is less than 12 hours before the next dose. (See Table 7.)

Concomitant medicinal products: Concomitant medicinal products that are strong inhibitors of CYP3A4 should be used with caution, and chronic use of concomitant medicinal products that are strong inducers of CYP3A4 should be avoided (see Precautions and Interactions).
Selection of an alternative concomitant medicinal product with no or minimal potential to induce or inhibit CYP3A4 should be considered.
Special populations: Elderly: No specific dose adjustment for the use of cabozantinib in elderly patients (≥65 years) is recommended.
Race: No dose adjustment is necessary based on ethnicity (see Pharmacology: Pharmacokinetics under Actions).
Renal impairment: Cabozantinib should be used with caution in patients with mild or moderate renal impairment.
Cabozantinib is not recommended for use in patients with severe renal impairment as safety and efficacy have not been established in this population.
Hepatic impairment: In patients with mild hepatic impairment no dose adjustment is required. Since only limited data are available for patients with moderate hepatic impairment (Child Pugh B), no dosing recommendation can be provided. Close monitoring of overall safety is recommended in these patients (see Precautions and Pharmacology: Pharmacokinetics under Actions). There is no clinical experience in patients with severe hepatic impairment (Child Pugh C), so cabozantinib is not recommended for use in these patients (see Pharmacology: Pharmacokinetics under Actions).
Cardiac impairment: There are limited data in patients with cardiac impairment. No specific dosing recommendations can be made.
Paediatric population: The safety and efficacy of cabozantinib in children and adolescents aged <18 years have not yet been established. Currently available data are described in Pharmacology: Pharmacokinetics under Actions but no recommendation on a posology can be made.
Method of administration: CABOMETYX is for oral use. The tablets should be swallowed whole and not crushed. Patients should be instructed to not eat anything for at least 2 hours before through 1 hour after taking CABOMETYX.
