Stivarga (regorafenib) is a kinase inhibitor used to treat patients with metastatic colorectal cancer (CRC). Common side effects of Stivarga include:

• weakness/fatigue,
• loss of appetite and decreased food intake,
• hand-foot skin reaction (HFSR),
• diarrhea,
• stomach pain,
• weight loss,
• infection,
• high blood pressure (hypertension),
• weakness,
• tiredness,
• voice changes or hoarseness, and
• swelling, pain, and redness of the lining of your mouth, throat, stomach, and bowel.

Stivarga can cause liver problems, which can be serious and sometimes fatal.

The recommended dose for Stivarga is 160 mg, orally, once daily for the first 21 days of each 28-day cycle. Stivarga should be taken with a low-fat breakfast. Stivarga may interact with grapefruit and grapefruit juice, bosentan, imatinib, nefazodone; St. John's wort, antibiotics, antifungals, heart medications, hepatitis C medications, HIV/AIDS medications, or seizure medications. Tell your doctor all medications and supplements you use. Stivarga is not recommended for use during pregnancy; it could harm a fetus. Use birth control to prevent pregnancy while you are receiving Stivarga, whether you are a man or a woman. Tell your doctor right away if a pregnancy occurs while either parent is taking Stivarga. Keep using birth control for at least 2 weeks after your treatment with Stivarga ends. It is unknown if Stivarga passes into breast milk or if it could harm a nursing baby. Consult your doctor before breastfeeding.

SIDE EFFECTS

The following serious adverse reactions are discussed elsewhere in the labeling:

• Hepatotoxicity [see WARNINGS AND PRECAUTIONS]
• Infections [(see WARNINGS AND PRECAUTIONS]
• Hemorrhage [see WARNINGS AND PRECAUTIONS]
• Gastrointestinal Perforation or Fistula [see WARNINGS AND PRECAUTIONS]
• Dermatological Toxicity [see WARNINGS AND PRECAUTIONS]
• Hypertension [see WARNINGS AND PRECAUTIONS]
• Cardiac Ischemia and Infarction [see WARNINGS AND PRECAUTIONS]
• Reversible Posterior Leukoencephalopathy Syndrome (RPLS) [see WARNINGS AND PRECAUTIONS]

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rate observed in practice.

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 or longer.

In randomized placebo-controlled trials (CORRECT, GRID, RESORCE and CONCUR), the most frequently observed adverse drug reactions ( ≥ 20%) in patients receiving STIVARGA 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.

Colorectal Cancer

The safety data described below, except where noted, are derived from a randomized (2:1), double-blind, placebo-controlled trial (CORRECT) in which 500 patients (median age 61 years; 61% men) with previously-treated metastatic colorectal cancer (CRC) received STIVARGA as a single agent at the dose of 160 mg daily for the first 3 weeks of each 4 week treatment cycle and 253 patients (median age 61 years; 60% men) received placebo. The median duration of therapy was 1.7 months (range 2 days, 10.8 months) for patients receiving STIVARGA. Due to adverse reactions, 61% of the patients receiving STIVARGA required a dose interruption and 38% of the patients had their dose reduced. Adverse reactions that resulted in treatment discontinuation occurred in 8.2% of STIVARGA-treated patients compared to 1.2% of patients who received placebo. Hand-foot skin reaction (HFSR) and rash were the most common reasons for permanent discontinuation of STIVARGA.

Table 1 provides the incidence of adverse reactions ( ≥ 10%) in patients in CORRECT.

Table 2 provides laboratory abnormalities observed in CORRECT.

Gastrointestinal Stromal Tumors

The safety data described below are derived from a randomized (2:1), double-blind, placebo-controlled trial (GRID) in which 132 patients (median age 60 years; 64% men) with previously-treated GIST received STIVARGA as a single agent at a dose of 160 mg daily for the first 3 weeks of each 4 week treatment cycle and 66 patients (median age 61 years; 64% men) received placebo. The median duration of therapy was 5.7 months (range 1 day, 11.7 months) for patients receiving STIVARGA. Dose interruptions for adverse events were required in 58% of patients receiving STIVARGA and 50% of patients had their dose reduced. Adverse reactions that resulted in treatment discontinuation were reported in 2.3% of STIVARGA-treated patients compared to 1.5% of patients who received placebo.

Table 3 provides the incidence of adverse reactions ( ≥ 10%) in patients in GRID.

Hepatocellular Carcinoma

The safety data described below are derived from a randomized (2:1), double-blind, placebo-controlled trial (RESORCE) in which patients with previously-treated HCC received either STIVARGA (n=374) 160 mg orally on days 1-21 of each 4 week treatment cycle or placebo (n=193). The median age was 63 years, 88% were men, 98% had Child-Pugh A cirrhosis, 66% had an ECOG performance status (PS) of 0 and 34% had PS of 1. The median duration of therapy was 3.5 months (range 1 day to 29.4 months) for patients receiving STIVARGA. Of the patients receiving STIVARGA, 33% were exposed to STIVARGA for greater than or equal to 6 months and 14% were exposed to STIVARGA for greater than or equal to 12 months. Dose interruptions for adverse events were required in 58.3% of patients receiving STIVARGA and 48% of patients had their dose reduced. The most common adverse reactions requiring dose modification (interruption or dose reduction) were HFSR/PPES (20.6%), blood bilirubin increase (5.9%), fatigue (5.1%) and diarrhea (5.3%). Adverse reactions that resulted in treatment discontinuation were reported in 10.4% of STIVARGA-treated patients compared to 3.6% of patients who received placebo; the most common adverse reactions requiring discontinuation of STIVARGA were HFSR/PPES (1.9%) and AST increased (1.6%).

Table 5 provides the incidence of adverse reactions ( ≥ 10%) in patients in RESORCE.

Table 5: Adverse reactions reported in ≥ 10% of patients treated with STIVARGA in RESORCE and reported more commonly than in patients receiving placebo^a

Other clinically significant adverse reactions observed in less than 10% of STIVARGA-treated patients were: alopecia (7%), hypothyroidism (6.4%), pancreatitis (1.6%), exfoliative rash (1.3%), tremor (1.3%), erythema multiforme (0.8%), myocardial ischemia (0.8%), gastrointestinal fistula (0.3%), and myocardial infarction (0.3%).

Postmarketing Experience

The following adverse reaction has been identified during postapproval use of STIVARGA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure:

• hypersensitivity reaction
