News Release - April 18, 2006
European Commission Grants Orphan Medicinal Product Designation to Nexavar for the Treatment of Hepatocellular CarcinomaWEST HAVEN, Conn. and EMERYVILLE, Calif., April 18 (HSMN NewsFeed) -- Bayer Pharmaceuticals Corporation (NYSE: BAY ) and Onyx Pharmaceuticals, Inc. (Nasdaq: ONXX ) announced today that NexavarŽ (sorafenib) tablets has been granted orphan medicinal product status for the treatment of hepatocellular carcinoma (HCC), or liver cancer, by the European Commission. This designation is based on a recommendation from the Committee for Orphan Medicinal Products (COMP) of the European Medicines Agency (EMEA).
"This orphan medicinal product designation demonstrates the European Commission's commitment to the study and development of treatments for rare diseases," said Susan Kelley, M.D., vice president, Oncology, Bayer Pharmaceuticals Corporation. "This support adds momentum to our research efforts with Nexavar and brings hope of a new treatment option to liver cancer patients in Europe."
At the 16th American Association for Cancer Research-National Cancer Institute-European Organization for Research and Treatment of Cancer (AACR- NCI-EORTC) meeting in 2004, investigators reported that in a Phase II single agent study, 43 percent of patients treated with Nexavar experienced stable disease for at least four months and an additional nine percent of patients experienced tumor shrinkage. The most common grade 3/4 drug-related toxicities were fatigue (9.5 percent), diarrhea (8 percent), and hand-foot skin reaction (5 percent). The toxicity profile of Nexavar was similar to previously reported safety analysis in patients with renal cell carcinoma.
A Phase III trial of Nexavar administered as a single agent is ongoing. The study is designed to measure differences in overall survival, time-to- symptom progression and time-to-tumor progression (TTP) of Nexavar versus placebo in liver cancer patients. A randomized Phase II trial for liver cancer patients to evaluate the efficacy of Nexavar in combination with the chemotherapeutic agent doxorubicin is also ongoing.
"Patients diagnosed with liver cancer have a poor prognosis due to the aggressive nature of the disease," said Dr. Jordi Bruix, head of the Barcelona Clinic Liver Cancer Group (BCLC), University of Barcelona, Spain. "The global medical community recognizes the need for new treatment therapies in liver cancer and I am encouraged by the study data we have seen so far in this patient population." Dr. Bruix is co-primary investigator along with Dr. Josep Llovet, Senior Scientist, Division of Liver Disease, Mount Sinai School of Medicine, New York.
Nexavar received approval from the U.S. Food and Drug Administration (FDA) in December 2005 to treat patients with advanced renal cell carcinoma (RCC), or kidney cancer. The European Commission has also granted Nexavar an orphan medicinal product designation for kidney cancer and a Marketing Authorization Application (MAA) had been submitted to the European Medicines Agency (EMEA) in September 2005 for approval to market Nexavar within the European Union for kidney cancer.
Orphan Drug Designation in the European Union
The EU orphan drug designation aims to encourage the development of drugs involved in the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition that affects no more than five in 10,000 persons in the European Union. The EU orphan drug designation does not shorten the duration of the regulatory review process.
Nexavar is the first oral multi-kinase inhibitor that targets both the tumor cell and tumor vasculature. In preclinical models, Nexavar targeted members of two classes of kinases known to be involved in both tumor cell proliferation (tumor growth) and tumor angiogenesis (tumor blood supply) - two important cancer growth activities. These kinases included RAF kinase, VEGFR- 2, VEGFR-3, PDGFR-B, KIT, and FLT-3.
Nexavar is currently in Phase III clinical trials for the treatment of liver cancer, metastatic melanoma, or skin cancer, and non-small cell lung cancer (NSCLC), and has been studied in more than 20 tumor types and in more than 8,000 clinical trial patients. In addition to company-sponsored trials, there are a variety of Nexavar studies being sponsored by government agencies, cooperative groups and individual investigators.
About Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC), also known as primary liver cancer, is the most common form of liver cancer and is responsible for 80 percent of the primary malignant liver tumors in adults. It is the fifth most common cancer in the world. HCC disproportionately affects men, with four times as many men developing the disease as women. In 2002, approximately 626,000 cases of HCC were reported worldwide (15,000 in the United States and 53,600 in Europe), and more than 600,000 deaths (about 13,000 Americans and 57,000 Europeans) due to HCC were reported. The five-year relative survival rate is about seven percent.
Important Safety Considerations for U.S. Patients Taking Nexavar
Based on the current, approved package insert for the treatment of patients with advanced kidney cancer, hypertension may occur early in the course of therapy and blood pressure should be monitored weekly during the first six weeks of therapy and treated as needed. Incidence of bleeding regardless of causality was 15% for Nexavar vs. 8% for placebo and the incidence of treatment-emergent cardiac ischemia/infarction was 2.9% for Nexavar vs. 0.4% for placebo. Most common treatment-emergent adverse events with Nexavar were diarrhea, rash/desquamation, fatigue, hand-foot skin reaction, alopecia, and nausea. Grade 3/4 adverse events were 38% for Nexavar vs. 28% for placebo. Women of child-bearing potential should be advised to avoid becoming pregnant and advised against breast-feeding. In cases of any severe or persistent side effects, temporary treatment interruption, dose modification or permanent discontinuation should be considered.
