CABOMETYX (Page 2 of 8)

2.6 Dosage Modifications for Coadministration with Strong CYP3A4 Inhibitors

Reduce the daily CABOMETYX dose by 20 mg (for example, from 60 mg to 40 mg daily or from 40 mg to 20 mg daily or from 20 mg daily to 20 mg every other day in pediatric patients with BSA less than 1.2 m2). Resume the dose that was used prior to initiating the strong CYP3A4 inhibitor 2 to 3 days after discontinuation of the strong inhibitor [see Drug Interactions (7.1), Clinical Pharmacology (12.3)].

2.7 Dosage Modifications for Coadministration with Strong CYP3A4 Inducers

Increase the daily CABOMETYX dose by 20 mg (for example, from 60 mg to 80 mg daily or from 40 mg to 60 mg daily) as tolerated. Resume the dose that was used prior to initiating the strong CYP3A4 inducer 2 to 3 days after discontinuation of the strong inducer. Do not exceed a daily dose of 80 mg [see Drug Interactions (7.1), Clinical Pharmacology (12.3)].

2.8 Dosage Modifications for Patients with Hepatic Impairment

Reduce the starting dose of CABOMETYX 60 mg daily to 40 mg daily or 40 mg daily to 20 mg daily (for pediatric patients with BSA less than 1.2 m2) in patients with moderate hepatic impairment (Child-Pugh B) [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].

2.9 Administration

Do not administer CABOMETYX with food. Administer at least 1 hour before or at least 2 hours after eating [see Clinical Pharmacology (12.3)].

  • Swallow CABOMETYX tablets whole. Do not crush CABOMETYX tablets.
  • Do not take a missed dose within 12 hours of the next dose.
  • Modify the CABOMETYX dose for patients taking drugs known to strongly induce or inhibit CYP3A4 and for patients with moderate hepatic impairment [see Dosage and Administration (2.6, 2.7, 2.8)].

5 WARNINGS AND PRECAUTIONS

5.1 Hemorrhage

Severe and fatal hemorrhages occurred with CABOMETYX [see Adverse Reactions (6.1)]. The incidence of Grade 3 to 5 hemorrhagic events was 5% in CABOMETYX-treated patients in RCC, HCC, and DTC studies.

Discontinue CABOMETYX for Grade 3 or 4 hemorrhage and prior to surgery as recommended [see Dosage and Administration (2.5), Warnings and Precautions (5.10, 5.11)]. Do not administer CABOMETYX to patients who have a recent history of hemorrhage, including hemoptysis, hematemesis, or melena.

5.2 Perforations and Fistulas

Fistulas, including fatal cases, occurred in 1% of CABOMETYX-treated patients [see Adverse Reactions (6.1)]. Gastrointestinal (GI) perforations, including fatal cases, occurred in 1% of CABOMETYX-treated patients.

Monitor patients for signs and symptoms of fistulas and perforations, including abscess and sepsis. Discontinue CABOMETYX in patients who experience a Grade 4 fistula or a GI perforation [see Dosage and Administration (2.5)].

5.3 Thrombotic Events

CABOMETYX increased the risk of thrombotic events [see Adverse Reactions (6.1)]. Venous thromboembolism occurred in 7% (including 4% pulmonary embolism) and arterial thromboembolism occurred in 2% of CABOMETYX-treated patients. Fatal thrombotic events occurred in CABOMETYX-treated patients.

Discontinue CABOMETYX in patients who develop an acute myocardial infarction or serious arterial or venous thromboembolic events that require medical intervention [see Dosage and Administration (2.5)].

5.4 Hypertension and Hypertensive Crisis

CABOMETYX can cause hypertension, including hypertensive crisis [see Adverse Reactions (6.1)]. Hypertension was reported in 37% (16% Grade 3 and <1% Grade 4) of CABOMETYX- treated patients.

Do not initiate CABOMETYX in patients with uncontrolled hypertension. Monitor blood pressure regularly during CABOMETYX treatment. Withhold CABOMETYX for hypertension that is not adequately controlled with medical management; when controlled, resume CABOMETYX at a reduced dose [see Dosage and Administration (2.5)]. Permanently discontinue CABOMETYX for severe hypertension that cannot be controlled with anti-hypertensive therapy or for hypertensive crisis [see Dosage and Administration (2.5)].

5.5 Diarrhea

Diarrhea occurred in 62% of patients treated with CABOMETYX. Grade 3 diarrhea occurred in 10% of patients treated with CABOMETYX [see Adverse Reactions (6.1)].

Monitor and manage patients using antidiarrheals as indicated. Withhold CABOMETYX until improvement to ≤ Grade 1, resume CABOMETYX at a reduced dose [see Dosage and Administration (2.5)].

5.6 Palmar-Plantar Erythrodysesthesia

Palmar-plantar erythrodysesthesia (PPE) occurred in 45% of patients treated with CABOMETYX [see Adverse Reactions (6.1)]. Grade 3 PPE occurred in 13% of patients treated with CABOMETYX.

Withhold CABOMETYX until improvement to Grade 1 and resume CABOMETYX at a reduced dose for intolerable Grade 2 PPE or Grade 3 PPE [see Dosage and Administration (2.5)].

5.7 Hepatotoxicity

CABOMETYX in combination with nivolumab can cause hepatic toxicity with higher frequencies of Grades 3 and 4 ALT and AST elevations compared to CABOMETYX alone.

Monitor liver enzymes before initiation of and periodically throughout treatment. Consider more frequent monitoring of liver enzymes as compared to when the drugs are administered as single agents. For elevated liver enzymes, interrupt CABOMETYX and nivolumab and consider administering corticosteroids [see Dosage and Administration (2.5)].

With the combination of CABOMETYX and nivolumab, Grades 3 and 4 increased ALT or AST were seen in 11% of patients [see Adverse Reactions (6.1)]. ALT or AST > 3 times ULN (Grade ≥2) was reported in 83 patients, of whom 23 (28%) received systemic corticosteroids; ALT or AST resolved to Grades 0-1 in 74 (89%). Among the 44 patients with Grade ≥2 increased ALT or AST who were rechallenged with either CABOMETYX (n=9) or nivolumab (n=11) as a single agent or with both (n=24), recurrence of Grade ≥2 increased ALT or AST was observed in 2 patients receiving CABOMETYX, 2 patients receiving nivolumab, and 7 patients receiving both CABOMETYX and nivolumab. Withhold and resume at a reduced dose based on severity [see Dosage and Administration (2.5)].

5.8 Adrenal Insufficiency

CABOMETYX in combination with nivolumab can cause primary or secondary adrenal insufficiency. For Grade 2 or higher adrenal insufficiency, initiate symptomatic treatment, including hormone replacement as clinically indicated. Withhold CABOMETYX and/or nivolumab and resume CABOMETYX at a reduced dose depending on severity [see Dosage and Administration (2.5)].

Adrenal insufficiency occurred in 4.7% (15/320) of patients with RCC who received CABOMETYX with nivolumab, including Grade 3 (2.2%), and Grade 2 (1.9%) adverse reactions. Adrenal insufficiency led to permanent discontinuation of CABOMETYX and nivolumab in 0.9% and withholding of CABOMETYX and nivolumab in 2.8% of patients with RCC.

Approximately 80% (12/15) of patients with adrenal insufficiency received hormone replacement therapy, including systemic corticosteroids. Adrenal insufficiency resolved in 27% (n=4) of the 15 patients. Of the 9 patients in whom CABOMETYX with nivolumab was withheld for adrenal insufficiency, 6 reinstated treatment after symptom improvement; of these, all (n=6) received hormone replacement therapy and 2 had recurrence of adrenal insufficiency.
