Renib

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.

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…

12.2 Pharmacodynamics Cardiac Electrophysiology The effect of multiple doses of STIVARGA (160 mg once daily for 21 days) on the QTc interval was evaluated in an open-label, single-arm study in 25 patients with advanced solid tumors. No large changes in the mean QTc interval (i.e., > 20 msec) were detected in the study.

6 ADVERSE REACTIONS The following serious adverse reactions are discussed elsewhere in the labeling: • Hepatotoxicity [see Warnings and Precautions ( 5.1 )] • Infections [see Warnings and Precautions ( 5.2 )] • Hemorrhage [see Warnings and Precautions ( 5.3 )] • Gastrointestinal Perforation or Fistula [see Warnings and Precautions ( 5.4 )] • Dermatological Toxicity [see Warnings and Precautions ( 5.5 )] • Hypertension [see Warnings and Precautions ( 5.6 )] • Cardiac Ischemia and Infarction [see Warnings and Precautions ( 5.7 )] • Reversible Posterior Leukoencephalopathy Syndrome (RPLS) [see Warnings and Precautions ( 5.8 )] The most common adverse reactions (≥20%) are pain (including gastrointestinal and abdominal pain), HFSR, asthenia/fatigue, diarrhea, decreased appetite/food intake, hypertension, infection, dysphonia, hyperbilirubinemia, fever, mucositis, weight loss, rash, and nausea.

The data described in the WARNINGS AND PRECAUTIONS section reflect exposure to STIVARGA in more than 4800 patients who were enrolled in four randomized, placebo-controlled trials (n=1142), an expanded access program (CONSIGN, n=2864), or single arm clinical trials (single agent or in combination with other agents). There were 4518 patients who received STIVARGA as a single agent; the distribution of underlying malignancies was 80% CRC, 4% GIST, 10% HCC, 6% other solid tumors; and 74% were White, 11% Asian, and 15% race not known. Among these 4518 patients, 83% received STIVARGA for at least 21 days and 20% received STIVARGA for 6 months…

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 after the final dose. Advise males to use effective contraception for 2 months after the final dose. ( 5.10 , 8.1 , 8.3 ) 5.1 Hepatotoxicity Severe drug-induced liver injury with fatal outcome occurred in STIVARGA-treated patients in clinical trials. In most cases, liver dysfunction occurred within the first 2 months of therapy and was characterized by a hepatocellular pattern of injury. Additionally, hyperammonemic encephalopathy, including fatal cases, have been reported in the postmarketing setting in patients treated with STIVARGA. The risk of hyperammonemic encephalopathy appears…

7 DRUG INTERACTIONS • Strong CYP3A4 inducers: Avoid strong CYP3A4 inducers. ( 7.1 ) • Strong CYP3A4 inhibitors: Avoid strong CYP3A4 inhibitors. ( 7.2 ) • BCRP substrates: Monitor patients closely for symptoms of increased exposure to BCRP substrates. ( 7.3 ) 7.1 Effect of Strong CYP3A4 Inducers on Regorafenib Co-administration of a strong CYP3A4 inducer with STIVARGA decreased the plasma concentrations of regorafenib, increased the plasma concentrations of the active metabolite M-5, and resulted in no change in the plasma concentrations of the active metabolite M-2 [see Clinical Pharmacology ( 12.3 )] , and may lead to decreased efficacy. Avoid concomitant use of STIVARGA with strong CYP3A4 inducers (e.g. rifampin, phenytoin, carbamazepine, phenobarbital, and St. John's Wort). 7.2 Effect of Strong CYP3A4 Inhibitors on Regorafenib Co-administration of a strong CYP3A4 inhibitor with STIVARGA increased the plasma concentrations of regorafenib and decreased the plasma concentrations of the active metabolites M-2 and M-5 [see Clinical Pharmacology ( 12.3 )] , and may lead to increased toxicity. Avoid concomitant use of STIVARGA with strong CYP3A4 inhibitors (e.g. clarithromycin, grapefruit juice, itraconazole, ketoconazole, nefazodone, posaconazole, telithromycin, and voriconazole). 7.3 Effect of Regorafenib on Breast Cancer Resistance Protein (BCRP) Substrates Co-administration of STIVARGA with a BCRP substrate increased the plasma concentrations of the BCRP substrate [see Clinical Pharmacology ( 12.3 )] . Monitor patients closely for signs and symptoms of exposure related toxicity to the BCRP substrate (e.g. methotrexate, fluvastatin, atorvastatin). Consult the concomitant BCRP substrate product information when considering administration of such products together with STIVARGA.
