Stivarga

Clinical summary

Indications and usage 1 INDICATIONS AND USAGE STIVARGA is a kinase inhibitor indicated for the treatment of adult patients with: • Metastatic colorectal cancer (CRC) who have been previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, an anti-VEGF therapy, and, if RAS wild-type, an anti-EGFR therapy. ( 1.1 ) • Locally advanced, unresectable or metastatic gastrointestinal stromal tumor (GIST) who have been previously treated with imatinib mesylate and sunitinib malate. ( 1.2 ) • Hepatocellular carcinoma (HCC) who have been previously treated with sorafenib ( 1.3 ) 1.1 Colorectal Cancer STIVARGA is indicated for the treatment of adult patients with metastatic colorectal cancer (CRC) who have been previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, an anti-VEGF therapy, and, if RAS wild-type, an anti-EGFR therapy. 1.2 Gastrointestinal Stromal Tumors STIVARGA is indicated for the treatment of adult patients with locally advanced, unresectable or metastatic gastrointestinal stromal tumor (GIST) who have been previously treated with imatinib mesylate and sunitinib malate. 1.3 Hepatocellular Carcinoma STIVARGA is indicated for the treatment of adult patients with hepatocellular carcinoma (HCC) who have been previously treated with sorafenib. Dosage and administration 2 DOSAGE AND ADMINISTRATION • Recommended dose: 160 mg orally, once daily for the first 21 days of each 28-day cycle. ( 2.1 ) • Take STIVARGA after a low-fat meal. ( 2.1 , 12.3 ) 2.1 Recommended Dose The recommended dose is 160 mg STIVARGA (four 40 mg tablets) taken orally once daily for the first 21 days of each 28-day cycle. Continue treatment until disease progression or unacceptable toxicity. Take STIVARGA at the same time each day. Swallow tablet whole with water after a low-fat meal that contains less than 600 calories and less than 30% fat [see Clinical Pharmacology ( 12.3 )] . Do not take two doses of STIVARGA on the same day to make up for a missed dose from the previous day. 2.2 Dose Modifications If dose modifications are required, reduce the dose in 40 mg (one tablet) increments; the lowest recommended daily dose of STIVARGA is 80 mg daily. Interrupt STIVARGA for the following: • Grade 2 hand-foot skin reaction (HFSR) [palmar-plantar erythrodysesthesia syndrome (PPES)] that is recurrent or does not improve within 7 days despite dose reduction; interrupt therapy for a minimum of 7 days for Grade 3 HFSR • Symptomatic Grade 2 hypertension • Any Grade 3 or 4 adverse reaction • Worsening infection of any grade Reduce the dose of STIVARGA to 120 mg: • For the first occurrence of Grade 2 HFSR of any duration • After recovery of any Grade 3 or 4 adverse reaction except infection • For Grade 3 aspartate aminotransferase (AST)/alanine aminotransferase (ALT) elevation, only resume if the potential benefit outweighs the risk of hepatotoxicity Reduce the dose of STIVARGA to 80 mg: • For re-occurrence of Grade 2 HFSR at the 120 mg dose • After recovery of any Grade 3 or 4 adverse reaction at the 120 mg dose (except hepatotoxicity or infection) Discontinue STIVARGA permanently for the following: • Failure to tolerate 80 mg dose • Any occurrence of AST or ALT more than 20 times the upper limit of normal (ULN) • Any occurrence of AST or ALT more than 3 times ULN with concurrent bilirubin more than 2 times ULN • Re-occurrence of AST or ALT more than 5 times ULN despite dose reduction to 120 mg • For any Grade 4 adverse reaction; only resume if the potential benefit outweighs the risks Warnings and cautions 5 WARNINGS AND PRECAUTIONS • Hepatotoxicity : Monitor liver function tests. Withhold and then reduce or discontinue STIVARGA based on severity and duration. ( 5.1 ) • Infections : Withhold STIVARGA in patients with worsening or severe infections. ( 5.2 ) • Hemorrhage : Permanently discontinue STIVARGA for severe or life-threatening hemorrhage. ( 5.3 ) • Gastrointestinal perforation or fistula : Discontinue STIVARGA. ( 5.4 ) • Dermatologic toxicity : Withhold and then reduce or discontinue STIVARGA depending on severity and persistence of dermatologic toxicity. ( 5.5 ) • Hypertension : Temporarily or permanently withhold STIVARGA for severe or uncontrolled hypertension. ( 5.6) • Cardiac ischemia and infarction : Withhold STIVARGA for new or acute cardiac ischemia/infarction and resume only after resolution of acute ischemic events. ( 5.7) • Reversible posterior leukoencephalopathy syndrome (RPLS) : Discontinue STIVARGA. ( 5.8) • Risk of impaired wound healing : Withhold for at least 2 weeks prior to elective surgery. Do not administer for at least 2 weeks after major surgery and until adequate wound healing. The safety of resumption of STIVARGA after resolution of wound healing complications has not been established. ( 5.9 ) • Embryo-fetal toxicity : Can cause fetal harm. Advise women of potential risk to a fetus and to use effective contraception during treatment and for 2 months
