Despite not meeting the primary endpoint, notable treatment effects were seen for L-BLP25 in certain subgroups. Patient safety in the START trial was monitored frequently by an independent data monitoring committee and no new or unexpected safety concerns were noted for the study. In prior clinical studies, the most frequently reported adverse events included injection site reactions, flu-like symptoms, nausea, cough, fatigue, and dyspnea. Further analyses are planned in the coming weeks to explore the potential benefit-risk profile of L-BLP25 in certain populations. This data will be discussed with external experts and regulatory authorities over the coming months. The START study results will be submitted for publication in a peer-reviewed journal and presented at a future international scientific meeting. The ongoing clinical program of L-BLP25 that includes studies in the Asia Pacific region will continue pending discussion with relevant regulatory agencies. "It is disappointing that the START trial did not meet its primary endpoint, in particular for patients suffering from NSCLC," said Dr. Frances Shepherd, Scott Taylor Chair in Lung Cancer Research at the Princess Margaret Hospital and Professor of Medicine at the University of Toronto, Canada, and Coordinating Investigator of the START trial. "However, notable treatment effects were observed in certain subgroups of patients and warrant further investigation of L-BLP25." "We believe that the START study will offer important scientific insights to the potential for immunotherapies in the treatment of this devastating disease and we intend to discuss these data with scientific community and regulatory authorities to gain their advice on potential next steps," said Dr. Annalisa Jenkins, Head of Global Drug Development and Medical for Merck Serono, a division of Merck KGaA, Darmstadt, Germany. START was a randomized, multicenter, double-blind, placebo-controlled trial that assessed the efficacy, safety and tolerability of L-BLP25 in more than 1,500 patients with unresectable stage III NSCLC who had achieved response or stable disease after chemoradiotherapy. a. START: Stimulating Targeted Antigenic Responses To NSCLC About L-BLP25 (Stimuvax®) L-BLP25 is an investigational MUC1 antigen-specific cancer immunotherapy that is designed to stimulate the body`s immune system to identify and target cells expressing the cell surface glycoprotein MUC1. MUC1 is expressed in many cancers, such as non-small cell lung cancer (NSCLC), and has multiple roles in promoting tumor growth and survival. L-BLP25 was being investigated in the Phase III START trial and is currently being investigated in the INSPIRE trial, both for the treatment of unresectable stage III NSCLC. Merck KGaA obtained the exclusive worldwide rights for development and commercialization of L-BLP25 from Oncothyreon Inc., Seattle, Washington, USA, in 2007, in an agreement replacing prior collaboration and supply agreements originally entered in 2001. In Japan, Merck KGaA entered into a co-development and co-marketing agreement for L-BLP25 with Ono Pharmaceutical Co., Ltd., Osaka, Japan. The START study was a Phase III, multi-center, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the efficacy, safety and tolerability of L-BLP25 in patients suffering from unresectable, stage IIIA or IIIB NSCLC who have had a response or stable disease after at least two cycles of platinum-based chemoradiotherapy. The study involves more than 1,500 patients in 33 countries. The primary endpoint of the START study is overall survival (OS). The INSPIRE study is a Phase III, multi-center, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the efficacy, safety and tolerability of L-BLP25 in patients of Asian heritage suffering from unresectable, stage IIIA or IIIB NSCLC who have had a response or stable disease after at least two cycles of platinum-based chemoradiotherapy. The design of the INSPIRE study is almost identical to the START study. INSPIRE will enroll approximately 420 unresectable, stage III NSCLC patients across China, Hong Kong, Korea, Singapore and Taiwan. About EMD Serono, Inc.
