Stivarga Side Effects Center

Stivarga (regorafenib) is a kinase inhibitor used for the treatment of patients with metastatic colorectal cancer (CRC). Stivarga can cause liver problems, which can be serious and sometimes fatal. The most common side effects with Stivarga are weakness/fatigue, decreased appetite and food intake, hand-foot skin reaction (HFSR), diarrhea, inflammation of mucus membranes, weight loss, infection, high blood pressure (hypertension), and voice disorders.

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 Tasigna (nilotinib), Tegretol (carbamazepine), Dilantin (phenytoin), phenobarbital, Rifadin (rifampin/rifampicin), Mycobutin (rifabutin), and Decadron (dexamethasone) nefazodone, Sporanox (itraconazole), Reyataz (atazanavir), and Crixivan (indinavir). Stivarga can cause fetal harm when given to a pregnant woman. It is not known whether Stivarga is present in breast milk. Consult your doctor to discuss whether to discontinue nursing or to discontinue Stivarga.

Stivarga FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

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

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 most frequently observed adverse drug reactions ( ≥ 20%) in patients receiving Stivarga are asthenia/fatigue, HFSR, diarrhea, decreased appetite/food intake, hypertension, mucositis, dysphonia, infection, pain (not otherwise specified), decreased weight, gastrointestinal and abdominal pain, rash, fever, and nausea.

The most serious adverse drug reactions in patients receiving Stivarga are hepatotoxicity, hemorrhage, and gastrointestinal perforation.

Clinical Trials Experience

Colorectal Cancer

The safety data described below, except where noted, are derived from a randomized (2:1), double-blind, placebo-controlled trial (Study 1) in which 500 patients (median age 61 years; 61% men) with previously treated metastatic colorectal cancer 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 7.3 (range 0.3, 47.0) weeks 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. Drug-related adverse reactions that resulted in treatment discontinuation were reported 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 compares the incidence of adverse reactions ( ≥ 10%) in patients receiving Stivarga and reported more commonly than in patients receiving placebo (Study 1).

Gastrointestinal Stromal Tumors

The safety data described below are derived from a randomized (2:1), double-blind, placebo-controlled trial (Study 2) 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 22.9 (range 0.1, 50.9) weeks 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. Drug-related adverse reactions that resulted in treatment discontinuation were reported in 2.3% of Stivargatreated patients compared to 1.5% of patients who received placebo.

Table 3 compares the incidence of adverse reactions ( ≥ 10%) in GIST patients receiving Stivarga and reported more commonly than in patients receiving placebo (Study 2).
