Hypertension: STIVARGA caused an increased incidence of hypertension (30% of STIVARGA-treated patients vs 8% of placebo-treated patients in Study 1). Hypertensive crisis occurred in 0.18% of 1100 STIVARGA-treated patients across all clinical trials. Do not initiate STIVARGA until blood pressure is adequately controlled. Monitor blood pressure weekly for the first 6 weeks of treatment and then every cycle, or more frequently, as clinically indicated. Temporarily or permanently withhold STIVARGA for severe or uncontrolled hypertension.
Cardiac Ischemia and Infarction: STIVARGA increased the incidence of myocardial ischemia and infarction (1.2% for STIVARGA-treated patients vs 0.4% of placebo-treated patients). Withhold STIVARGA in patients who develop new or acute cardiac ischemia or infarction, and resume only after resolution of acute cardiac ischemic events if the potential benefits outweigh the risks of further cardiac ischemia.
Reversible Posterior Leukoencephalopathy Syndrome (RPLS): RPLS occurred in 1 of 1100 STIVARGA-treated patients across all clinical trials. Confirm the diagnosis of RPLS with MRI and discontinue STIVARGA in patients who develop RPLS.
Gastrointestinal Perforation or Fistula: Gastrointestinal perforation or fistula occurred in 0.6% of 1100 patients treated with STIVARGA across clinical trials. Permanently discontinue STIVARGA in patients who develop gastrointestinal perforation or fistula.
Wound Healing Complications: Treatment with STIVARGA should be stopped at least 2 weeks prior to scheduled surgery. The decision to resume STIVARGA after surgery should be based on clinical judgment of adequate wound healing. STIVARGA should be discontinued in patients with wound dehiscence.
Embryo-Fetal Toxicity: STIVARGA can cause fetal harm when administered to a pregnant woman. Use effective contraception during treatment and up to 2 months after completion of therapy. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.
Nursing Mothers: Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from STIVARGA, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Most Frequently Observed Adverse Drug Reactions in Metastatic Colorectal Cancer (mCRC) (≥30%): The most frequently observed adverse drug reactions (≥30%) in STIVARGA-treated patients vs placebo-treated patients in mCRC, respectively, were: asthenia/fatigue (64% vs 46%), decreased appetite and food intake (47% vs 28%), HFSR/PPE (45% vs 7%), diarrhea (43% vs 17%), mucositis (33% vs 5%), weight loss (32% vs 10%), infection (31% vs 17%), hypertension (30% vs 8%), and dysphonia (30% vs 6%).

About Nexavar® (sorafenib) Tablets
Nexavar is approved in the U.S. for the treatment of patients with unresectable hepatocellular carcinoma and for the treatment of patients with advanced renal cell carcinoma. Nexavar is thought to inhibit both the tumor cell and tumor vasculature. In preclinical studies, Nexavar has been shown to inhibit multiple kinases thought to be involved in both cell proliferation (growth) and angiogenesis (blood supply) - two important processes that enable cancer growth. These kinases include Raf kinase, VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-B, KIT, FLT-3 and RET.
