Nexavar
Co-developed and co-marketed with Bayer, sorafenib—sold under the trade name Nexavar—is a drug approved in the United States for the treatment of advanced renal cell carcinoma (kidney cancer) in 2005, and for the treatment of inoperable hepatocellular carcinoma, the most common form of liver cancer, in 2007. Sorafenib has also been evaluated in other types of cancer, including thyroid (as a treatment of last resort) and breast (in comparison to capecitabine).
In July 2014, the company announced the phase III failure of a Sorafenib-Capecitabine combination trial. The drug combination failed to increase progression free survival of patients with advanced breast cancer.
Kyprolis
Carfilzomib, marketed under the trade name Kyprolis, was approved on June 20, 2012, by the FDA for use in patients with multiple myeloma who have received at least two prior therapies, including treatment with bortezomib and an immunotherapy, and have demonstrated disease progression on or within 60 days of completion of the most recent therapy. Carfilzomib is also being evaluated in other stages of multiple myeloma. The most commonly reported adverse reactions (incidence ≥ 30%) are fatigue, anemia, nausea, thrombocytopenia, shortness of breath, diarrhea and fever.
Stivarga
Regorafenib (marketed under the trade name Stivarga) is currently being studied as a potential treatment option in multiple tumor types. On September 27, 2012, the FDA approved regorafenib for the treatment of patients with metastatic colorectal cancer who have been previously treated with fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapy, an anti-VEGF therapy, and, if KRAS wild-type, an anti-EGFR therapy. On February 25, 2013, the FDA approved regorafenib in a second indication to treat patients with locally advanced, unresectable or metastatic gastrointestinal stromal tumor (GIST) who have been previously treated with imatinib mesylate and sunitinib malate. Regorafenib is a compound developed by Bayer. The most common adverse reactions (≥ 20%) are asthenia/fatigue, hand-foot skin reaction (HFSR), diarrhea, decreased appetite/food intake, hypertension, mucositis, dysphonia and infection, pain (not otherwise specified), weight loss, abdominal pain, rash, fever and nausea. In 2011, Bayer entered into an agreement with Onyx under which Onyx will receive a 20 percent royalty on any future global net sales of regorafenib in oncology. Bayer and Onyx jointly promote Stivarga in the United States.
