News Release - July 23, 2012
Addition of Tarceva(R) (erlotinib) to Nexavar(R) (sorafenib) did not Provide Additional Benefit to Patients with Unresectable Liver Cancer Versus Nexavar alone in Phase 3 TrialWAYNE, N.J., SOUTH SAN FRANCISCO, Calif. and TOKYO, July 23, 2012 -- (Healthcare Sales & Marketing Network) -- Bayer HealthCare Pharmaceuticals, Onyx Pharmaceuticals, Inc. (ONXX), and Astellas Pharma Inc. (TSE:4503) today announced that a Phase 3 trial evaluating the efficacy and safety of the addition of Tarceva® (erlotinib) tablets to Nexavar® (sorafenib) tablets did not improve overall survival for patients with unresectable hepatocellular carcinoma (HCC) vs. Nexavar alone. The SEARCH (Sorafenib and Erlotinib, a rAndomized tRial protoCol for the treatment of patients with Hepatocellular carcinoma) trial compared Nexavar in combination with Tarceva to Nexavar alone. The safety and tolerability of the treatment combination were generally as expected based upon experience and use of the two products alone and there were no new or unexpected toxicities or changes to the respective product safety profiles observed. Data from this study will be presented at an upcoming scientific meeting. Nexavar is jointly developed by Bayer and Onyx. Tarceva is jointly marketed by Astellas and Genentech, a member of the Roche Group.
"The data from SEARCH showed that the addition of Tarceva to Nexavar did not provide additional benefit to patients with unresectable HCC," said Dr. Dimitris Voliotis, Vice President, Global Clinical Development Oncology, Bayer HealthCare. "The results of this trial confirm the efficacy and safety profile of Nexavar in the treatment of unresectable liver cancer."
About the Phase 3 Study
The SEARCH trial was an international multicenter placebo-controlled Phase 3 study that randomized 720 patients with advanced liver cancer. The study examined whether the addition of Tarceva to Nexavar prolongs survival as compared to Nexavar alone in patients with unresectable HCC. The primary endpoint of the study was overall survival (OS) and the secondary endpoints were safety, time to radiographic progression (TTP), disease control rate (DCR) and patient-reported outcome. Patients were randomized to receive either 400 mg of Nexavar twice daily and 150 mg of Tarceva once daily or 400 mg of Nexavar twice daily with matching placebo.
About Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC) is the most common form of liver cancer and is responsible for approximately 90 percent of the primary liver cancers in adults. Liver cancer is the seventh most common cancer in the world and the third leading cause of cancer-related deaths globally.
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.
Nexavar is currently approved in more than 100 countries.
Nexavar is also being evaluated by Bayer and Onyx, international study groups, government agencies and individual investigators in a range of cancers.
Important Safety Considerations For Nexavar (sorafenib)
Nexavar in combination with carboplatin and paclitaxel is contraindicated in patients with squamous cell lung cancer.
Nexavar may cause fetal harm when administered to a pregnant woman. Women of childbearing potential are advised to avoid becoming pregnant and female patients should also be advised against breastfeeding while receiving Nexavar.
Cardiac ischemia and/or myocardial infarction may occur. Temporary or permanent discontinuation of Nexavar should be considered in patients who develop cardiac ischemia and/or myocardial infarction.
Gastrointestinal perforation was an uncommon adverse reaction and has been reported in less than 1% of patients taking Nexavar.
Uncommon but serious adverse reactions, including keratoacanthomas/squamous cell cancer of the skin and Stevens-Johnson Syndrome, have been reported in clinical trials.
An increased risk of bleeding may occur following Nexavar administration. If bleeding necessitates medical intervention, consider discontinuation of Nexavar.
Hypertension may occur early in the course of treatment. Monitor blood pressure weekly during the first 6 weeks and periodically thereafter and treat, as required.
Hand-foot skin reaction and rash are common and management may include topical therapies for symptomatic relief. In cases of any severe or persistent adverse reactions, temporary treatment interruption, dose modification, or permanent discontinuation of Nexavar should be considered. Temporary interruption of Nexavar therapy is recommended in patients undergoing major surgical procedures.
Nexavar can prolong the QT/QTc interval and increase the risk for ventricular arrhythmias. Avoid use in patients with congenital long QT syndrome and monitor patients with congestive heart failure, bradyarrhythmias, drugs known to prolong the QT interval, and electrolyte abnormalities.
Elevations in serum lipase and reductions in serum phosphate of unknown etiology have been associated with Nexavar. Monitor patients taking concomitant warfarin regularly for changes in prothrombin time, INR, or clinical bleeding episodes. Avoid concomitant use of strong CYP3A4 inducers, when possible, because inducers can decrease the systemic exposure of sorafenib. Nexavar exposure decreases when co-administered with oral neomycin. Effects of other antibiotics on Nexavar pharmacokinetics have not been studied.
Most common adverse reactions reported for Nexavar-treated patients vs placebo-treated patients in unresectable HCC, respectively, were: diarrhea (55% vs 25%), fatigue (46% vs 45%), abdominal pain (31% vs 26%), weight loss (30% vs 10%), anorexia (29% vs 18%), nausea (24% vs 20%), and hand-foot skin reaction (21% vs 3%). Grade 3/4 adverse reactions were 45% vs 32%.
Most common adverse reactions reported for Nexavar-treated patients vs placebo-treated patients in advanced RCC, respectively, were: diarrhea (43% vs 13%), rash/desquamation (40% vs 16%), fatigue (37% vs 28%), hand-foot skin reaction (30% vs 7%), alopecia (27% vs 3%),and nausea (23% vs 19%). Grade 3/4 adverse reactions were 38% vs 28%.
During post approval use of Nexavar, the following adverse drug reactions have been identified: angioedema and drug-induced hepatitis, including reports of hepatic failure and death.

Maintenance Therapy and Second- or Third-Line Therapy in Advanced Non-Small Cell Lung Cancer (NSCLC):
Tarceva is prescribed for patients with advanced-stage non-small cell lung cancer (NSCLC) whose cancer has not spread or grown after initial treatment with certain types of chemotherapy. (Maintenance treatment)
Tarceva is prescribed for patients with advanced-stage non-small cell lung cancer (NSCLC) whose cancer has spread or grown after receiving at least 1 chemotherapy regimen. (2nd/3rd-line treatment)
Tarceva is not meant to be used at the same time as certain types of chemotherapy for advanced NSCLC.
Advanced Pancreatic Cancer:
Tarceva in combination with gemcitabine is prescribed for patients with advanced-stage pancreatic cancer whose cancer has spread, grown, or cannot be surgically removed and who have not received previous chemotherapy.
Important Safety Information for Tarceva
Serious side effects (including deaths) in patients taking Tarceva include Interstitial Lung Disease (ILD)-like events; liver and/or kidney problems; gastrointestinal (GI) perforations (the development of a hole in the stomach, small intestine, or large intestine); serious skin conditions; and bleeding events including gastrointestinal and non-gastrointestinal bleeding when taking warfarin or non-steroidal anti-inflammatory drugs (NSAIDs). Patients taking Tarceva plus gemcitabine were more likely to experience bleeding and clotting problems such as heart attack or stroke. Eye irritation and damage to the cornea have been reported in patients taking Tarceva. Women should avoid becoming pregnant and avoid breastfeeding while taking Tarceva. Patients should call their doctor right away if they have these signs or symptoms: new or worsening skin rash; serious or ongoing diarrhea, nausea, loss of appetite, or vomiting; new or worsening shortness of breath or cough; or eye irritation. Rash and diarrhea were the most common side effects associated with Tarceva in the non-small cell lung cancer clinical studies. Fatigue, rash, nausea, loss of appetite, and diarrhea were the most common side effects associated with Tarceva plus gemcitabine therapy in the advanced pancreatic cancer clinical study.
