Company Provides Updated Financial and Milestone Guidance
in Connection with Recent Strategic Transactions and Clinical Trials Progress

SOUTH SAN FRANCISCO, CA, July 31, 2013 - Cytokinetics, Incorporated (Nasdaq: CYTK) reported total research and development revenues for the second quarter of 2013 were $1.0 million, compared to $1.8 million during the same period in 2012. The second quarter revenue does not include $33.5 million in deferred revenue related to the agreements entered into with Amgen Inc. and Astellas Pharma Inc. in June 2013.  The net loss for the second quarter was $15.0 million, or $0.58 per basic and diluted share.  This is compared to a net loss allocated to common stockholders for the same period in 2012, of $10.3 million, or $0.76 per basic and diluted share, which included a one-time, non-cash dividend of $1.3 million related to the beneficial conversion feature of the Series B convertible preferred stock.   As of June 30, 2013, cash, cash equivalents and investments totaled $75.7 million, which includes the receipt of $15 million from the expansion of our strategic collaboration with Amgen for omecamtiv mecarbil and $10 million for the sale of common stock to Amgen, but does not include $16.0 million received from Astellas in July 2013.

"In the second quarter, Cytokinetics announced important strategic transactions and progress in our lead development-stage programs," stated Robert I. Blum, Cytokinetics' President and Chief Executive Officer. "A new collaboration with Astellas and an expanded alliance with Amgen afford us increased resources and opportunities to take key steps forward as we are advancing multiple drug candidates from our leading muscle biology directed research.  We believe that Cytokinetics is well-positioned in both our cardiac and skeletal muscle activator programs to deliver on the promise they may represent for patients suffering from grievous illnesses and we are looking forward to the results from our Phase II clinical trials."

Updated Financial Guidance for 2013

Cytokinetics also announced its updated financial guidance for 2013.  The company anticipates cash revenue will be approximately $40 to $42 million, cash R&D expenses will be in the range of $52 to $55 million, and cash G&A expenses will be in the range of $15 to $16 million.  This financial guidance is on a cash basis and does not include the deferral of approximately $10 million in revenue to future calendar years and an estimated $5.6 million in non-cash related operating expenses primarily related to stock compensation expense.

Company Highlights

Cardiac Muscle Contractility

omecamtiv mecarbil

• During the quarter, Cytokinetics announced that results from ATOMIC-AHF (Acute Treatment with Omecamtiv Mecarbil to Increase Contractility in Acute Heart Failure) have been accepted for presentation during a Hot Line Late Breaking Trials Session at the European Society of Cardiology (ESC) Congress. ATOMIC-AHF is a Phase IIb clinical trial designed to evaluate the safety, tolerability and efficacy of an intravenous formulation of omecamtiv mecarbil compared to placebo in patients with left ventricular systolic dysfunction who are hospitalized with acute heart failure.  

• Recently, cohort 2 of COSMIC-HF (Chronic Oral Study of Myosin Activation to Increase Contractility in Heart Failure) opened to enrollment.  This Phase II, double-blind, randomized, placebo-controlled, multicenter, dose escalation study is designed to evaluate three modified-release oral formulations of omecamtiv mecarbil in patients with heart failure and left ventricular systolic dysfunction. COSMIC-HF is expected to inform the selection of an oral formulation of omecamtiv mecarbil for potential advancement into the Phase III clinical development program.  

• During the quarter, Cytokinetics and Amgen reviewed results from a recently completed Phase I, open-label, single-dose clinical trial designed to compare the pharmacokinetics of omecamtiv mecarbil in patients undergoing hemodialysis versus healthy volunteers.  No clinically meaningful differences were observed in this study in the pharmacokinetics of omecamtiv mecarbil administered to patients undergoing hemodialysis versus healthy volunteers.  

The trials described above were or are being conducted by Amgen in collaboration with Cytokinetics.  Additional information on these and other clinical trials of omecamtiv mecarbil can be found at www.clinicaltrials.gov.

Skeletal Muscle Contractility

tirasemtiv

• We are conducting BENEFIT-ALS (Blinded Evaluation of Neuromuscular Effects and Functional Improvement with Tirasemtiv in ALS) at over 70 sites across the United States, Canada and several European countries. To date, we have enrolled over 500 patients in BENEFIT-ALS. Cytokinetics recently announced that it had been informed by its data management vendor that a programming error in the electronic data capture system controlling study drug assignment for the on-going BENEFIT-ALS clinical trial caused 58 patients initially randomized to and treated with tirasemtiv to receive placebo instead at a certain study visit and for the remainder of the study. No patients randomized to placebo were dispensed incorrect treatment. Cytokinetics and all clinical trial personnel remain blinded to the specific patients affected by the error.  Following detection of the error, the company took steps to ensure that no further incorrect study drug assignments occurred and to correct the programming error in the electronic data capture system controlling study drug assignment.  In addition, we convened an ad hoc meeting of the study's Data Safety Monitoring Board (DSMB) to assess whether the error in dispensing study drug had impacted the safety of the 58 affected patients.  After review of the relevant safety data from BENEFIT-ALS, the DSMB reported no concerns regarding patient safety. 

• Following interactions with regulatory authorities, Cytokinetics amended the protocol for BENEFIT-ALS to enable increased enrollment to approximately 680 patients and to update the statistical methods section, in both cases with the objective to maintain the originally intended statistical power of the trial.  

CK-2127107

• During the quarter, Cytokinetics continued to enroll patients in CY 5011, a first-time-in-humans, Phase I clinical trial of CK-2127107, a novel small molecule activator of the fast skeletal muscle troponin complex, in healthy male volunteers. CY 5011 is a double-blind, randomized, placebo-controlled study designed to assess the safety, tolerability, and pharmacokinetics of single ascending oral doses of CK-2127107 administered in a three-period crossover design.  

Pre-Clinical Research

• During the quarter, Cytokinetics continued to conduct research under our joint research program with Amgen directed to the discovery of next-generation cardiac sarcomere activators.  In addition, the company continued research activities directed to other muscle biology programs.   

• In June, Cytokinetics announced the publication of three peer-reviewed manuscripts co-authored by company scientists and a group led by Dr. Henk Granzier, Professor of Physiology, and Norville Endowed Chair, Molecular Cardiovascular Research Program, University of Arizona. These publications describe translational research conducted by Dr. Granzier's laboratory in collaboration with Cytokinetics in which the effects of fast skeletal muscle troponin activation were explored in nemaline myopathy, a rare, sarcomere-based disease.  

Corporate

• In June, Cytokinetics announced an expansion of our strategic collaboration with Amgen to include Japan.  In consideration of this expansion, Cytokinetics received $25 million from Amgen comprised of a $15 million non-refundable license fee and $10 million for Amgen's purchase of 1.4 million shares of Cytokinetics' common stock.  Cytokinetics is also eligible to receive additional pre-commercialization milestone payments for the development of omecamtiv mecarbil in Japan of up to $50 million, as well as royalties on sales of omecamtiv mecarbil in Japan.     As of June 30, 2013, the Company determined that all conditions necessary for revenue recognition under the accounting guidelines had not been met.  The Company will defer the recognition of the $15.0 million license fee under this amendment to the collaboration agreement until these criteria have been satisfied, which we anticipate will be in the third quarter 2013.  

• In June, Cytokinetics and Astellas Pharma Inc. announced a collaboration focused on the research, development and commercialization of skeletal muscle activators. The primary objective of the collaboration is to advance novel therapies for diseases and medical conditions associated with muscle weakness. The parties will jointly conduct research in the area of skeletal muscle activation. Astellas will have exclusive rights to develop and commercialize drug candidates that may arise from these activities, subject to certain Cytokinetics' development and commercialization rights.  As part of this collaboration, Cytokinetics has exclusively licensed to Astellas the rights to co-develop and commercialize CK-2127107, for potential applications in non-neuromuscular indications. CK-2127107 will be developed jointly by Cytokinetics and Astellas.  Under the agreement, Cytokinetics will be 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. Astellas will have 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. Astellas will have the exclusive right to commercialize collaboration products worldwide, subject to Cytokinetics' option to co-promote collaboration products in the United States and Canada.  In July, Cytokinetics received a $16.0M non-refundable upfront payment and is eligible to potentially receive over $24.0M in reimbursement of sponsored research and development activities during the initial two years of the collaboration. In addition, Cytokinetics is eligible to receive over $450 million in pre-commercialization and commercialization milestones plus royalties. The Company will recognize the $16.0 million upfront license fee ratably over the 24 month period of the research plan with Astellas.  

• In June, Cytokinetics filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation to effect a one-for-six reverse stock split of its common stock. As of June 30, 2013, there were 28,685,215 basic shares outstanding and 41,495,272 fully diluted shares outstanding. 

• In June, Cytokinetics was added as a member of the Russell Global, Russell 3000, Russell 2000 and Russell Microcap Indexes as Russell Investments reconstituted its comprehensive family of global indexes.

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, a debilitating disease of neuromuscular impairment. 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.
