Technologies. The collaboration will leverage Cytokinetics' proprietary platform, Cytometrix(TM) cellular phenotyping technologies, which are routinely utilized in Cytokinetics' screening processes to analyze both on-target and off-target effects of candidate compounds. Cytometrix(TM) cellular phenotyping technologies utilize cell-based assays to create digital phenotypic profiles ("fingerprints") representative of diverse molecular mechanisms of drug action. Cytometrix(TM) fingerprints detail information on the potency and specificity of a compound or drug-related toxicities. Cytokinetics presently employs Cytometrix(TM) cellular phenotyping technologies to eliminate compounds of mixed mechanism, allowing the company to focus its medicinal chemistry and pharmacology resources more selectively on higher quality chemical series. This collaboration with AstraZeneca is designed to develop a new Cytometrix(TM) technologies application called the Cytometrix(TM) Hepatotoxicity Module for the in vitro prediction of hepatotoxicities downstream of screening. - more - ABOUT CYTOKINETICS Founded in 1998 and privately held, Cytokinetics is dedicated to the discovery, development and commercialization of a novel class of therapeutics resulting from its leadership position in the emerging field of cytoskeletal pharmacology. The cytoskeleton is a complex, dynamic framework that impacts all aspects of cell function including cell division, cell motility, intracellular transport, muscle contractility and regulation of cellular organization. Cytokinetics' R&D efforts aim to address pharmaceutical needs in cancer, cardiovascular and infectious diseases and feature proprietary Cytometrix(TM) cellular phenotyping technologies designed to industrialize cell biology for increased speed and productivity in drug discovery and development. Cytokinetics and GlaxoSmithKline have entered into a broad strategic collaboration to discover, develop and commercialize novel small molecule therapeutics targeting mitotic kinesins for applications in the treatment of cancer and other diseases. Cytokinetics and GlaxoSmithKline are conducting Phase I studies with the first novel anti-cancer drug candidate emerging from the collaboration and intend to expand clinical development upon completion of these studies.
