                     Field of Skeletal Muscle Activation


   Collaboration Will Focus on Expanding the New Frontier of Muscle Biology

 Cytokinetics is Eligible to Receive Over $40 Million During the Initial Two

South San Francisco, CA, and Tokyo,June 25, 2013 - Cytokinetics,  Incorporated 
(NASDAQ:CYTK)  and  Astellas   Pharma  Inc.  (Tokyo   Stock  Exchange:   4503, 
"Astellas")  announced  today  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 the exclusive rights  to develop and  commercialize drug candidates  that 
may arise from these activities, subject to certain Cytokinetics'  development 
and commercialization rights. In addition, Cytokinetics has granted  Astellas 
an exclusive  license  to  co-develop  and  commercialize  Cytokinetics'  drug 
candidate CK-2127107 in certain indications. 

In this collaboration, Cytokinetics will combine its foremost position in  the 
discovery and mechanistic  biology of  small molecule  activators of  skeletal 
muscle  contractility  with   Astellas'  advanced  pharmaceutical   discovery, 
development,  and   commercialization   capabilities.  During   the   two-year 
collaborative research term,  the companies will  focus on expanding  emerging 
opportunities in  skeletal muscle  contractility and  will together  identify, 
characterize,  and  optimize  fast  skeletal  troponin  activators  and  other 
potential novel  mechanism skeletal  muscle  activators. The  joint  research 
program is designed to leverage  the two companies' cutting-edge  capabilities 
in  discovery   technologies,  medicinal   chemistry,  analytical   chemistry, 
structural biology, computational  chemistry, and the  pharmacology of  muscle 

"We are pleased  to enter into  this collaboration with  Astellas, which  will 
enable us  to expand  our research  and development  in the  area of  skeletal 
muscle  activators,"  stated  Cytokinetics'  President  and  Chief   Executive 
Officer, Robert I.  Blum. "Through  this collaboration, we  intend to  jointly 
investigate the potential role that  CK-2127107 and follow-on skeletal  muscle 
activators can  play in  providing functional  improvements in  patients  with 
diseases characterized by muscle weakness and fatigue. We are impressed  with 
Astellas' strategic vision and  capabilities in the  areas of novel  mechanism 
biopharmaceutical research and development."

"We are excited to work with Cytokinetics to expand the new frontier of muscle
biology related to the very innovative mechanism of action of skeletal  muscle 
activation,"  stated  Yoshihiko  Hatanaka,   Astellas'  President  and   Chief 
Executive Officer. "This  new collaboration  illustrates Astellas'  important 
commitment to enhance its abilities to generate innovative drugs by  deploying 
cutting-edge science, accessing  distinguished internal  and external  talent, 
and utilizing the optimal research environment."

Under the collaboration, Cytokinetics has exclusively licensed to Astellas the
rights to co-develop  and commercialize CK-2127107,  a fast skeletal  troponin 
activator drug  candidate,  for  potential  application  in  non-neuromuscular 
indications. CK-2127107, which is currently in Phase I clinical  development, 
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.   Outside   the 
collaboration, Cytokinetics will continue to independently develop tirasemtiv,
a fast skeletal troponin activator currently in Phase II clinical trials,  for 
the  potential   treatment  of   amyotrophic  lateral   sclerosis  and   other 
neuromuscular disorders.

Cytokinetics is eligible to receive over $40 million in the form of an upfront
payment and  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 parties will jointly conduct
research  to  identify  next-generation  skeletal  muscle  activators  to   be 
nominated as drug candidates. Astellas will be responsible for the activities
and  costs  associated  with   the  development  of  collaboration   products. 
Cytokinetics retains an option to conduct early-stage development for certain
agreed indications  at  its  initial  expense,  subject  to  reimbursement  if 
development  continues  under  the  collaboration.  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  connection with  the co-promotion  activities, Astellas  will 
reimburse Cytokinetics  for certain  expenses  associated with  its  promotion
