The FDA approved Stivarga (regorafenib) to treat patients with colorectal cancer that has progressed after treatment and spread to other parts of the body (metastatic).
Stivarga is a multi-kinase inhibitor that blocks several enzymes that promote cancer growth. The drug was reviewed under the FDA’s priority review program that provides an expedited six-month review for drugs that offer major advances in treatment or that provide treatment when no adequate therapy exists.
According to the Centers for Disease Control and Prevention, colorectal cancer is the third most common cancer in men and in women and the third leading cause of cancer death in men and in women in the United States. The National Institutes of Health estimates 143,460 Americans will be diagnosed with colorectal cancer, and 51,690 will die from the disease in 2012.
Stivarga is being approved with a Boxed Warning alerting patients and health care professionals that severe and fatal liver toxicity occurred in patients treated with Stivarga during clinical studies. The most common side effects reported in patients treated with Stivarga include weakness or fatigue, loss of appetite, hand-foot syndrome (also called palmar-plantar erythrodysesthesia), diarrhea, mouth sores (mucositis), weight loss, infection, high blood pressure, and changes in voice volume or quality (dysphonia).
In August 2012, the FDA approved Zaltrap (ziv-aflibercept) for use in combination with a FOLFIRI (folinic acid, fluorouracil and irinotecan) chemotherapy regimen to treat adults with metastatic colorectal cancer.
