Bayer AG's Bayer HealthCare Pharmaceuticals And Onyx Pharmaceuticals, Inc.'s Phase 3 DECISION Trial Of Nexavar (sorafenib) Meets Primary Endpoint
Bayer AG's Bayer HealthCare Pharmaceuticals and Onyx Pharmaceuticals, Inc. announced that a Phase 3 trial of Nexavar (sorafenib) tablets in patients with locally advanced or metastatic radioactive iodine-refractory (RAI) differentiated thyroid cancer has met primary endpoint of a statistically improvement of progression-free survival. The study, called DECISION, evaluated efficacy and safety of Nexavar compared to placebo. Adverse events were generally consistent with the known profile for Nexavar. The companies anticipate that this data will form basis for regulatory submission of Nexavar in treatment of RAI-refractory differentiated thyroid cancer. The DECISION (study of sorafenib in locally advanced or metastatic patients with radioactive Iodine refractory thyroid cancer) trial was an international, multicenter, randomized, placebo-controlled study that randomized 417 patients with locally advanced or metastatic, radioactive iodine-refractory, differentiated thyroid cancer (papillary, follicular, Hurthle cell and poorly differentiated) who had received no prior chemotherapy, tyrosine kinase inhibitors, monoclonal antibodies that target VEGF or VEGF receptor, or other targeted agents for thyroid cancer. The primary endpoint of study was progression-free survival, as defined by Response Evaluation Criteria in Solid Tumors. Secondary endpoints included overall survival, time to progression, response rate and duration of response. Full Article

Onyx Pharmaceuticals, Inc., Bayer AG's HealthCare Pharmaceuticals And Astellas Pharma Inc Announce Tarceva To Nexavar Did Not Provide Additional Benefit To Patients
Onyx Pharmaceuticals, Inc., Bayer AG's HealthCare Pharmaceuticals and Astellas Pharma Inc announced that a Phase III 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. Nexavar is jointly developed by Bayer and Onyx. Tarceva is jointly marketed by Astellas and Genentech, a member of the Roche Group. The SEARCH trial was an international multicenter placebo-controlled Phase III 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.

The primary efficacy endpoint was overall response (ORR) and determined by an Independent Review Committee using the International Myeloma Working Group (IMWG) criteria. ORR was 22.9% and median response duration was 7.8 months. Full Article
