Cytokinetics, Incorporated (Cytokinetics) is a biopharmaceutical company focused on the discovery and development of small molecule therapeutics that modulate muscle function for the potential treatment of serious diseases and medical conditions. Only marginally SBIR Involved and that primarily some years ago, the Companys R&D programs relating to the biology of muscle function are directed to small molecule modulators of the contractility of cardiac, skeletal and smooth muscle. The cardiac muscle contractility program is focused on cardiac sarcomere, the basic unit of muscle contraction in the heart. Its lead drug candidate CK-2017357 is subject of a Phase IIa clinical trials program. CK-2017357 is useful in treating diseases or medical conditions associated with skeletal muscle weakness or wasting. In March 2010, CK-2017357 received an orphan drug designation from the FDA for the treatment of amyotrophic lateral sclerosis
