Cytokinetics, Inc.: Cytokinetics Announces Initiation of Multiple Dose Phase I Clinical Trial of CK-2127107 Commencement of Study Triggers Milestone Payment from Astellas South San Francisco, CA, March 27, 2014 - Cytokinetics, Incorporated (Nasdaq: CYTK) announced the initiation of an additional Phase I clinical trial of CK-2127107, a fast skeletal muscle troponin activator. The trial, called CY5012, is a double-blind, randomized, placebo-controlled, parallel group study in which the primary objective is to assess the safety, tolerability, and pharmacokinetics of CK-2127107 following multiple ascending doses in healthy volunteers. The initiation of this clinical trial triggers a $2 million milestone payment from Astellas Pharma Inc. (Tokyo Stock Exchange: 4503, "Astellas") to Cytokinetics under the terms of the collaboration between the companies established in June 2013. In CY 5012, volunteers in each ascending dose cohort will be randomized to receive either CK-2127107 or placebo. CY 5012 will separately enroll cohorts of volunteers in two age groups, one between the ages of 18 and 55 and one between the ages of 65 and 85. Each cohort will be comprised of six male and six female participants. In each cohort, volunteers will receive CK-2127107 or placebo in accordance with 2:1 randomization. An initial cohort in each age group will receive 300 mg of CK-2127107 or placebo to be followed by a second cohort in each age group that will receive 1000 mg of CK-2127107 or placebo. Doses of CK-2127107 and placebo will be administered orally for 10 days. If these doses of CK-2127107 are well-tolerated, a final cohort of volunteers between the ages of 18 and 55 will receive CK-2127107 at either 1500 mg or 2000 mg, to be determined following a review of data from the prior dose cohorts or placebo. In each cohort, pharmacokinetic assessments will be performed following the first dose of CK-2127107 and throughout the study to day 10. "This multi-dose clinical trial of CK-2127107 is another in the series of Phase I trials that Cytokinetics is conducting on behalf of the collaboration," stated Fady Malik, MD, PhD, Cytokinetics' Senior Vice President, Research and Early Development. "These studies along with other Phase II readiness activities will inform the potential progression of CK-2127107 into a Phase II development program focused on non-neuromuscular indications." Development Status of CK-2127107 Cytokinetics previously reported the results of the first-time-in-humans clinical trial of CK-2127107, called CY5011. This Phase I clinical trial was a double-blind, randomized, placebo-controlled study designed to assess the safety, tolerability, and pharmacokinetics of single ascending oral doses of CK-2127107 administered to healthy adult males in a three-period, escalating dose, crossover design. Planned single doses of CK-2127107 up to 4000 mg, the highest dose administered in the trial, were well-tolerated; therefore, a maximum tolerated dose could not be defined. The pharmacokinetic profile of CK-2127107 was linear and dose-proportional across the dose range studied, with a mean terminal half-life compatible with once or twice daily dosing. In addition, Cytokinetics recently completed dosing in CY 5014, a Phase I clinical trial of CK-2127107 in healthy male volunteers. CY 5014 is a randomized, open-label, two-period crossover study designed to assess the relative oral bioavailability, pharmacokinetics, safety and tolerability of two oral formulations of CK-2127107. Cytokinetics and Astellas Collaboration CY 5012 is being conducted by Cytokinetics in collaboration with Astellas. Cytokinetics and Astellas entered into a collaboration in June 2013 to advance novel therapies, including CK-2127107, for diseases and medical conditions associated with muscle weakness. Cytokinetics has exclusively licensed to Astellas the rights to co-develop and commercialize CK-2127107 for potential application in non-neuromuscular indications. Cytokinetics is primarily responsible for the conduct of Phase I clinical trials and certain Phase II readiness activities for CK-2127107 and Astellas will be primarily responsible for the conduct of subsequent development and commercialization activities for CK-2127107. Cytokinetics and Astellas are jointly conducting research in the area of skeletal muscle activation. Astellas has exclusive rights to develop and commercialize other fast skeletal troponin activators in non-neuromuscular indications and to develop and commercialize other novel mechanism skeletal muscle activators in all indications, subject to certain Cytokinetics' development and commercialization rights. Under the collaboration, Cytokinetics is eligible to receive over $450 million in pre-commercialization and commercialization milestones plus royalties. Background on Skeletal Muscle Activators Skeletal muscle contractility is driven by the sarcomere, the fundamental unit of skeletal muscle contraction. It is a highly ordered cytoskeletal structure composed of several key proteins. The first, skeletal muscle myosin, is the cytoskeletal motor protein that converts chemical energy into mechanical force through its interaction with a second protein, actin. A set of regulatory proteins, which includes tropomyosin and several types of troponin, make the actin-myosin interaction dependent on changes in intracellular calcium levels. In non-clinical models, CK-2127107 slows the rate of calcium release from the regulatory troponin complex of fast skeletal muscle fibers, which sensitizes the sarcomere to calcium, leading to an increase in skeletal muscle contractility. CK-2127107 and other skeletal sarcomere activators have demonstrated pharmacological activity that may lead to new therapeutic options for diseases associated with aging and muscle wasting. The clinical effects of muscle wasting, fatigue and loss of mobility can range from decreased quality of life to life-threatening complications. By directly improving skeletal muscle function, a small molecule activator of the skeletal sarcomere may potentially enhance physical performance and quality of life in patients with conditions marked by muscle weakness and fatigue. About Cytokinetics Cytokinetics is a clinical-stage biopharmaceutical company focused on the discovery and development of novel small molecule therapeutics that modulate muscle function for the potential treatment of serious diseases and medical conditions. Cytokinetics' lead drug candidate from its cardiac muscle contractility program, omecamtiv mecarbil, is in Phase II clinical development for the potential treatment of heart failure. Amgen Inc. holds an exclusive license worldwide to develop and commercialize omecamtiv mecarbil and related compounds, subject to Cytokinetics' specified development and commercialization participation rights. Cytokinetics is independently developing tirasemtiv, a fast skeletal muscle activator, as a potential treatment for diseases and medical conditions associated with neuromuscular dysfunction. Tirasemtiv is currently the subject of a Phase II clinical trials program and has been granted orphan drug designation and fast track status by the U.S. Food and Drug Administration and orphan medicinal product designation by the European Medicines Agency for the potential treatment of amyotrophic lateral sclerosis (ALS). Cytokinetics is collaborating with Astellas Pharma Inc. to develop CK-2127107, a skeletal muscle activator structurally distinct from tirasemtiv, for non-neuromuscular indications. All of these drug candidates have arisen from Cytokinetics' muscle biology focused research activities and are directed towards the cytoskeleton. The cytoskeleton is a complex biological infrastructure that plays a fundamental role within every human cell. Additional information about Cytokinetics can be obtained at www.cytokinetics.com.
