DEAR SHAREHOLDER,
The sarcomere, the fundamental unit of 
muscle contractility, is the cornerstone of 
Cytokinetics’  drug  discovery  and  the 
engine for mechanical force, power and 
endurance  in  human  biology.  It  also 
serves  as  the  focal  point  of  our  R&D 
activities  and  has  been  a  source  of 
strength and inspiration throughout our 
history  of  pioneering  innovation.  The 
sarcomere again delivered for us in 2018 
as we advanced three new compounds arising from our research

worldwide  and  this  disease  representing  one  of  the  leading 
contributors  to  increasing  Medicare  costs,  novel  approaches 
to  treatment  are  desperately  needed  to  reduce  symptoms, 
hospitalization  and  death  associated  with  a  diagnosis  of 
heart failure, particularly given our rapidly aging demographics. 

In our neuromuscular program, we demonstrated progress with 
reldesemtiv, our fast skeletal troponin muscle activator (FSTA), which 
we are developing in collaboration with Astellas. A Phase 2 clinical 
trial in patients with spinal muscular atrophy showed increases in

of endurance consistent with the mechanism of action, in patients 
treated with reldesemtiv. We were encouraged by these data and

Overview

We are a late-stage biopharmaceutical company focused on discovering, developing and commercializing first-in-class muscle 
activators  and  best-in-class  muscle  inhibitors  as  potential  treatments  for  debilitating  diseases  in  which  muscle  performance  is 
compromised  and/or  declining.  We  have  discovered  and  are  developing  muscle-directed  investigational  medicines  that  may 
potentially improve the healthspan of people with devastating cardiovascular and neuromuscular diseases of impaired muscle function. 
Our research and development activities relating to the biology of muscle function have evolved from our knowledge and expertise 
regarding the cytoskeleton, a complex biological infrastructure that plays a fundamental role within every human cell. As a leader in 
muscle biology and the mechanics of muscle performance, we are developing small molecule drug candidates specifically engineered 
to impact muscle function and contractility. 

Our drug candidates currently in clinical development are: omecamtiv mecarbil, a novel cardiac myosin activator which we are 
developing for the potential treatment of heart failure, reldesemtiv, a novel fast skeletal muscle troponin activator (“FSTA”) which we 
are  developing  for  the  potential  treatment  of  amyotrophic  lateral  sclerosis  (“ALS”)  and  spinal  muscular  atrophy  (“SMA”),  CK-
3773274  (“CK-274”),  a  novel  cardiac  myosin  inhibitor,  which  we  are  developing  for  the  potential  treatment  of  hypertrophic 
cardiomyopathy (“HCM”) and AMG 594, a novel cardiac troponin activator which is the subject of a Phase 1 clinical study.

Omecamtiv  mecarbil  is  being  evaluated  for  the  potential  treatment  of  heart  failure  under  a  strategic  alliance  with  Amgen 
established in 2006 to discover, develop, and commercialize novel small molecule therapeutics designed to activate cardiac muscle 
contractility  pursuant  to  the  collaboration  and  option  agreement  dated  December  29,  2006,  as  amended  (the  “Amgen  Agreement”). 
Amgen, in collaboration with Cytokinetics, is conducting GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes 
Through Improving Contractility in Heart Failure), a Phase 3 cardiovascular outcomes clinical trial of omecamtiv mecarbil in heart 
failure. In collaboration with Amgen, we are conducting METEORIC-HF (Multicenter Exercise Tolerance Evaluation of Omecamtiv 
Mecarbil  Related  to  Increased  Contractility  in  Heart  Failure),  a  second  Phase  3  clinical  trial  intended  to  evaluate  its  potential  to 
increase exercise performance.

Reldesemtiv  selectively  activates  the  fast  skeletal  muscle  troponin  complex  in  the  sarcomere  by  increasing  its  sensitivity  to 
calcium,  leading  to  an  increase  in  skeletal  muscle  contractility.  Cytokinetics  and  Astellas  are  developing  reldesemtiv  under  the 
Amended  and  Restated  License  and  Collaboration  Agreement  dated  December  22,  2014,  as  amended  (the  “Astellas  Agreement”). 
Astellas  holds  an  exclusive  license  to  develop  and  commercialize  reldesemtiv  worldwide,  subject  to  our  development  and 
commercialization participation rights. In collaboration with Astellas, we conducted a Phase 2 clinical trial of reldesemtiv in patients 
with SMA and we are conducting a Phase 2 clinical trial of reldesemtiv in patients with ALS, called FORTITUDE-ALS (Functional 
Outcomes  in  a  Randomized  Trial  of  Investigational  Treatment  with  CK-2127107  to  Understand  Decline  in  Endpoints  –  in  ALS). 
Astellas,  in  collaboration  with  us,  conducted  a  Phase  2  clinical  trial  of  reldesemtiv  in  patients  with  chronic  obstructive  pulmonary 
disease (“COPD”) and a Phase 1b clinical trial of reldesemtiv in elderly subjects with limited mobility. 

CK-274 is a novel, oral, small molecule cardiac myosin inhibitor that we discovered independent of our collaborations. CK-274 
arose  from  an  extensive  chemical  optimization  program  conducted  with  careful  attention  to  therapeutic  index  and  pharmacokinetic 
properties that may translate into best-in-class potential in clinical development. CK-274 was designed to reduce the hypercontractility 
that is associated with HCM. In preclinical models, CK-274 reduces myocardial contractility by binding directly to cardiac myosin at 
a distinct and selective allosteric binding site, thereby preventing myosin from entering a force producing state. CK-274 reduces the 
number  of  active  actin-myosin  cross  bridges  during  each  cardiac  cycle  and  consequently  reduces  myocardial  contractility.  This 
mechanism of action may be therapeutically effective in conditions characterized by excessive hypercontractility, such as HCM. We 
are conducting a Phase 1 double-blind, randomized, placebo-controlled, multi-part, single and multiple ascending dose clinical trial of 
CK-274 in healthy adult subjects.

AMG  594  was  discovered  under  our  joint  research  program  with  Amgen.  In  collaboration  with  Cytokinetics,  Amgen  is 
conducting a randomized, placebo-controlled, double-blind, single and multiple ascending dose, single-center Phase 1 study to assess 
the safety and tolerability, pharmacokinetics and pharmacodynamics of AMG 594 in healthy subjects.

Our research continues to drive innovation and leadership in muscle biology, evidenced by three new muscle biology directed 
compounds advancing from research to development in 2018. All of our drug candidates have arisen from our cytoskeletal research 
activities.  Our  focus  on  the  biology  of  the  cytoskeleton  distinguishes  us  from  other  biopharmaceutical  companies,  and  potentially 
positions us to discover and develop novel therapeutics that may be useful for the treatment of severe diseases and medical conditions. 
Each of our drug candidates has a novel mechanism of action compared to currently marketed drugs, which we believe validates our 
focus on the cytoskeleton as a productive area for drug discovery and development. We intend to leverage our experience in muscle 
contractility to expand our current pipeline and expect to identify additional potential drug candidates that may be suitable for clinical 
development.

Corporate Strategy 

We are a late-stage biopharmaceutical company focused on discovering, developing and commercializing first-in-class muscle 
activators  and  best-in-class  muscle  inhibitors  as  potential  treatments  for  debilitating  diseases  in  which  muscle  performance  is 
compromised  and/or  declining.  As  a  leader  in  muscle  biology  and  the  mechanics  of  muscle  performance,  we  are  developing  small 
molecule  drug  candidates  specifically  engineered  to  impact  muscle  function  and  contractility.  Our  goal  is  to  discover,  develop and 
commercialize  novel  drug  products  that  modulate  muscle  function  that  may  benefit  people  living  with  serious  diseases  or  medical 
conditions, with the intent of establishing a fully-integrated biopharmaceutical company. 

The key components of our Corporate Strategy are: 

•

•

•

•

•

Progress  proprietary  research  programs  focused  on  muscle  into  development.    We  believe  that  our  extensive 
understanding of muscle biology and our proprietary research technologies should enable us to discover and potentially to 
develop drug candidates with novel mechanisms of action that may offer potential benefits not provided by existing drugs 
and which may have application across a broad array of diseases and medical conditions. We expect that we may be able 
to leverage our expertise in muscle contractility to expand programs related to other areas of muscle function and which 
may extend to the potential treatment of other serious medical diseases and conditions. Progressing related programs in 
parallel  may  afford  us  an  opportunity  to  build  a  broader  business  that  could  benefit  from  multiple  products  that  serve 
related  clinical  and  commercial  needs  associated  with  impaired  muscle  function,  muscle  weakness  and  fatigue.  In 
addition, this strategy may enable us to diversify certain technical, financial and operating risks by advancing several drug 
candidates in parallel. 

Advance  next-generation  skeletal  and  cardiac  muscle-directed  compounds  into  clinical  development.    We  take  a 
purpose-driven  approach  by  leveraging  our  extensive  muscle  biology  expertise  to  engineer  compounds  with  specific 
characteristics aimed at treating diseases that impact muscle function. By increasing muscle strength and performance, our 
drug candidates may preserve and extend independence and self-reliance in people suffering from debilitating diseases. 
We have established select strategic alliances to support certain drug development programs while preserving significant 
development and commercialization rights. We believe that such alliances may allow us to obtain financial support and to 
capitalize on the therapeutic area expertise and resources of our partners that can potentially accelerate the development 
and commercialization of our drug candidates. Where we deem appropriate, we plan to retain certain rights to participate 
in  the  development  and  commercialization  of  drug  candidates  arising  from  our  programs  and  alliances,  so  that  we  can 
expand and capitalize on our own internal development capabilities and build our commercialization capabilities. 

Conduct  clinical  development  of  novel,  first-in-class  and/or  best-in-class  muscle  activators/inhibitors  for  the  potential 
treatment  of  ALS,  SMA,  heart  failure,  HCM  and  other  diseases  impacting  muscle  function.    Our  portfolio  consists  of 
drug candidates that are in clinical development in principally four therapeutic areas, namely ALS, SMA, heart failure and 
HCM  which  may  also  inform  their  further  development  in  other  diseases  characterized  by  either  limited  or  excessive 
muscle  function.  We  believe  that  by  focusing  on  these  disease  areas  that  are  associated  with  well-organized  physician-
investigator  groups,  significant  unmet  clinical  needs,  and  strong  patient  and  disease  advocacy,  we  may  enhance  our 
effectiveness  in  enrolling  and  conducting  clinical  trials  to  answer  important  questions  about  the  dosing,  tolerability, 
pharmacokinetics and pharmacodynamics as well as the potential safety and efficacy of our drug candidates. We believe 
that our development programs can improve our ability to realize value from our and our partners’ clinical development 
activities.  As  we  advance  our  drug  candidates  into  later-stage  clinical  development,  we  extensively  evaluate  previous 
clinical  trial  designs  and  results  to  assess  key  learnings  that  may  be  applied  to  our  late-stage  clinical  development 
activities. We believe this may result in more successful later-stage clinical development activities that may increase the 
likelihood of developing effective therapies that can address the needs of people living with these devastating diseases.

Collaborate  with  patient  communities  to  support  the  urgent  development  of  new  medicines  for  diseases  of  impaired 
muscle function with pressing unmet medical needs.    Central to our corporate strategy are the people living with a disease 
or  medical  condition  characterized  by  impaired  muscle  function.  We  focus  our  development  and  commercialization 
activities on diseases that lack effective therapies and, in some cases, those with no approved medicines. We recognize 
that by applying our extensive knowledge of muscle biology towards the development of novel therapies for the people 
living  with  these  diseases,  we  aim  to  improve  lives  of  not  only  patients  but  also  their  caregivers  and  families.  We 
collaborate with these individuals and their communities to ensure our potential drugs address their urgent needs and that 
we  understand  and  appreciate  the  issues  associated  with  these  diseases  and  conditions.  We  work  collaboratively  with 
entities, such as patient advocacy groups, that focus on policies, guidelines and practices to accelerate development and 
commercialization  of  novel  therapies,  when  possible  and  appropriate,  and  on  ensuring  that  the  voice  of  their 
constituencies are heard. 

Mature  our  company’s  operations  to  enable  development,  registration  and  commercialization  of  muscle  biology  drug 
candidates across North America and Europe.    With a focus on disease areas for which there are serious unmet medical 
needs,  we  direct  our  activities  to  potential  commercial  opportunities  in  concentrated  and  tractable  customer  segments, 
such as hospital specialists and disease-specific centers of excellence, which may be addressed by smaller, targeted sales 

4

forces. In preparing for the potential commercialization of our drug candidates directed to these markets, we are focusing 
our activities on the key issues facing patients and payors, including the principal drivers of clinical and economic burdens 
associated with these diseases. We also focus on opportunities that multiple stakeholders may recognize as creating value. 
Accordingly,  targeting  unmet  medical  needs  in  these  areas  may  provide  us  competitive  advantages  and  support  our 
development of a potential franchise in diseases involving muscle function. In these markets, we believe that a company 
with  limited  resources  may  be  able  to  compete  effectively  against  larger,  more  established  companies  with  greater 
financial  and  commercial  resources.  For  these  opportunities,  we  intend  to  develop  clinical  development  and  sales  and 
marketing  capabilities  in  North  America  and  Europe  with  the  goal  of  becoming  a  fully-integrated  biopharmaceutical 
company.

Research and Development Programs

Our  long-standing  interest  in  the  cytoskeleton  has  led  us  to  focus  our  research  and  development  activities  on  the  biology  of 
muscle function and, in particular, small molecule modulation of muscle contractility. We believe that our expertise in the modulation 
of muscle contractility is an important differentiator for us. Our preclinical and clinical experience in muscle contractility may position 
us  to  discover  and  develop  additional  novel  therapies  that  have  the  potential  to  improve  the  health  of  patients  with  severe  and 
debilitating diseases or medical conditions.

Small  molecules  that  affect  muscle  contractility  may  have  several  applications  for  a  variety  of  serious  diseases  and  medical 
conditions. For example, heart failure is a disease often characterized by impaired cardiac muscle contractility which may be treated 
by modulating the contractility of cardiac muscle. Similarly, certain diseases and medical conditions associated with muscle weakness 
may  be  amenable  to  treatment  by  enhancing  the  contractility  of  skeletal  muscle.  Because  the  modulation  of  the  contractility  of 
different types of muscle, such as cardiac and skeletal muscle, may be relevant to multiple diseases or medical conditions, we believe 
we  can  leverage  our  expertise  in  these  areas  to  more  efficiently  discover  and  develop  potential  drug  candidates  that  modulate  the 
applicable muscle type for multiple indications.

We segment our research and development activities related to muscle contractility by our cardiac muscle contractility program 
and our skeletal muscle contractility program.  We also conduct research and development on novel treatments for disorders involving 
muscle function beyond muscle contractility.

Our research and development expenses were $89.1 million for 2018, $90.3 million for 2017 and $59.9 million for 2016.

Cardiac Muscle Program

Our cardiac muscle contractility program is focused on the cardiac sarcomere, the basic unit of muscle contraction in the heart. 
The cardiac sarcomere is a highly ordered cytoskeletal structure composed of cardiac myosin, actin and a set of regulatory proteins. 
Cardiac myosin is the cytoskeletal motor protein in the cardiac muscle cell. It is directly responsible for converting chemical energy 
into the mechanical force, resulting in cardiac muscle contraction. Our most advanced cardiac program is based on the hypothesis that 
activators of cardiac myosin may address certain adverse properties of existing positive inotropic agents. Current positive inotropic 
agents, such as beta-adrenergic receptor agonists or inhibitors of phosphodiesterase activity, increase the concentration of intracellular 
calcium, thereby increasing cardiac sarcomere contractility. The effect on calcium levels, however, also has been linked to potentially 
life-threatening side effects. In contrast, our novel cardiac myosin activators work by a mechanism that directly stimulates the activity 
of the cardiac myosin motor protein, without increasing the intracellular calcium concentration. They accelerate the rate-limiting step 
of  the  myosin  enzymatic  cycle  and  shift  it  in  favor  of  the  force-producing  state.  Rather  than  increasing  the  velocity  of  cardiac 
contraction, this mechanism instead lengthens the systolic ejection time, which results in increased cardiac function in a potentially 
more oxygen-efficient manner.

Our earlier stage cardiac program is based on the hypothesis that inhibitors of hyperdynamic contraction and obstruction of left 
ventricular blood flow may counteract the pathologic effects of mutations in the sarcomere that lead to hypertrophic cardiomyopathies. 
A  targeted  oral  therapy  addressing  this  disease  etiology  may  improve  symptoms,  exercise  capacity  and  potentially  slow  disease 
progression. 

Omecamtiv mecarbil

Our lead drug candidate from our cardiac contractility program is omecamtiv mecarbil, a novel cardiac myosin activator. We 
expect omecamtiv mecarbil to be developed as a potential treatment across the continuum of care in heart failure both for use in the 
hospital setting and for use in the outpatient setting. Omecamtiv mecarbil is the subject of a Phase 3 development program in patients 
with heart failure with reduced ejection fraction under our strategic alliance with Amgen.

Amgen Strategic Alliance

Our  strategic  alliance  with  Amgen  to  discover,  develop,  and  commercialize  novel  small  molecule  therapeutics  designed  to 
activate  cardiac  muscle,  including  omecamtiv  mecarbil,  for  the  potential  treatment  of  heart  failure  is  governed  by  the  Amgen 
Agreement.  Amgen  has  exclusive,  worldwide  rights  to  develop  and  commercialize  omecamtiv  mecarbil  and  related  compounds 

5

subject to our specified development and commercial participation rights. Amgen has also entered an alliance with Les Laboratoires 
Servier and Institut de Recherches Internationales Servier (“Servier”) for exclusive commercialization rights in Europe as well as the 
Commonwealth of Independent States (“CIS”), including Russia. Servier contributes funding for development and provides strategic 
support to the program.

Under  the  Amgen  Agreement  we  are  eligible  for  potential  additional  pre-commercialization  and  commercialization  milestone 
payments of over $600.0 million in the aggregate on omecamtiv mecarbil and other potential products arising from research under the 
collaboration,  and  royalties  that  escalate  based  on  increasing  levels  of  annual  net  sales  of  products  commercialized  under  the 
agreement. 

The  Amgen  Agreement  provided  for  us  to  receive  increased  royalties  by  co-funding  the  Phase  3  development  program  for 
omecamtiv mecarbil and other drug candidates under the collaboration. We fully exercised this option and co-invested $40.0 million 
in the Phase 3 development program of omecamtiv mecarbil in exchange for a total incremental royalty from Amgen of up to 4% on 
increasing worldwide sales of omecamtiv mecarbil outside Japan and the right to co-promote omecamtiv mecarbil in institutional care 
settings  in  North  America,  with  reimbursement  by  Amgen  for  certain  sales  force  activities  (the  “Co-Invest  Option”).  A  joint 
commercial operating team comprising representatives of Cytokinetics and Amgen will be responsible for the day-to-day management 
of the commercialization program of omecamtiv mecarbil. 

Amgen  generally  has  discretion  to  elect  whether  to  pursue  or  abandon  the  development  of  omecamtiv  mecarbil  and  may 
terminate our strategic alliance for any reason upon six months’ prior notice. With our consent, Amgen granted Servier an option to 
commercialize omecamtiv mecarbil in Europe and the CIS, including Russia, which Servier decided to exercise. In August 2016, we 
entered into a letter agreement with Amgen and Servier, which provides that if Amgen’s rights to omecamtiv mecarbil are terminated 
with respect to the territory subject to Servier’s sublicense, the sublicensed rights previously granted by Amgen to Servier with respect 
to omecamtiv mecarbil, will remain in effect and become a direct license or sublicense of such rights by us to Servier, on substantially 
the same terms as those in the Option, License and Collaboration Agreement between Amgen and Servier.

Omecamtiv Mecarbil: Clinical Development

GALACTIC-HF:  GALACTIC-HF  (Global  Approach  to  Lowering  Adverse  Cardiac  Outcomes  Through  Improving 
Contractility in Heart Failure) is a Phase 3 cardiovascular outcomes clinical trial of omecamtiv mecarbil which is being conducted by 
Amgen,  in  collaboration  with  Cytokinetics.  The  primary  objective  of  this  double-blind,  randomized,  placebo-controlled  multicenter 
clinical trial is to determine if treatment with omecamtiv mecarbil when added to standard of care is superior to standard of care plus 
placebo in reducing the risk of cardiovascular death or heart failure events in patients with high risk chronic heart failure and reduced 
ejection fraction. GALACTIC-HF is being conducted under a Special Protocol Assessment (“SPA”) with the FDA. GALACTIC-HF is 
planned  to  enroll  approximately  8,000  symptomatic  chronic  heart  failure  patients  in  over  900  sites  in  35  countries  who  are  either 
currently hospitalized for a primary reason of heart failure or have had a hospitalization or admission to an emergency room for heart 
failure within one year prior to screening. Patients are randomized to either placebo or omecamtiv mecarbil with dose titration up to a 
maximum dose of 50 mg twice daily based on the plasma concentration of omecamtiv mecarbil after initiation of drug therapy. The 
primary endpoint is a composite of time to cardiovascular death or first heart failure event, whichever occurs first, with heart failure 
event  defined  as  hospitalization,  emergency  room  visit,  or  urgent  unscheduled  clinic  visit  for  heart  failure.  Secondary  endpoints 
include time to cardiovascular death; patient reported outcomes as measured by the Kansas City Cardiomyopathy Questionnaire Total 
Symptom Score; time to first heart failure hospitalization; and all-cause death.

METEORIC-HF:  In  collaboration  with  Amgen,  we  are  conducting  METEORIC-HF  (Multicenter  Exercise  Tolerance 
Evaluation of Omecamtiv Mecarbil Related to Increased Contractility in Heart Failure), a second Phase 3 clinical trial intended to 
evaluate its potential to increase exercise performance. Patients will be randomized in a 2:1 fashion to omecamtiv mecarbil, which will 
be started at 25 mg twice daily and titrated to 25, 37.5 or 50 mg twice daily based on the same PK-guided dosing regimen as is used in 
GALACTIC-HF, or to placebo. METEORIC-HF is planned to enroll approximately 270 symptomatic chronic heart failure patients in 
nine  countries.  The  primary  endpoint  of  METEORIC-HF  is  change  in  peak  oxygen  uptake  on  Cardio-Pulmonary  Exercise  Testing 
(“CPET”) from baseline to Week 20. Secondary endpoints include change in total workload during CPET from baseline to Week 20, 
change in ventilatory efficiency during CPET from baseline to Week 20 and change in the average daily activity units measured over 
2 weeks from baseline to Week 18-20. 

AMG 594

AMG 594 is a novel, selective, oral, small molecule cardiac troponin activator which was discovered under our joint research 
program with Amgen. In preclinical models, AMG 594 increases myocardial contractility by binding to cardiac troponin through an 
allosteric  mechanism  that  sensitizes  the  cardiac  sarcomere  to  calcium,  facilitating  more  actin-myosin  cross  bridge  formation  during 
each cardiac cycle thereby resulting in increased myocardial contractility. Similar to cardiac myosin activation, preclinical research 
has  shown  that  cardiac  troponin  activation  does  not  change  the  calcium  transient  of  cardiac  myocytes.  In  collaboration  with 
Cytokinetics, Amgen is conducting a randomized, placebo-controlled, double-blind, single and multiple ascending dose, single-center 
Phase  1  study  to  assess  the  safety  and  tolerability,  pharmacokinetics  and  pharmacodynamics  of  AMG  594  in  healthy  subjects.  The 
study design includes several single ascending dose cohorts and three multiple ascending dose cohorts, with eight healthy subjects per 
cohort.

Omecamtiv Mecarbil: Heart Failure Commercial Market

Heart failure is a widespread and debilitating syndrome affecting millions of people in the United States. The high and rapidly 
growing  prevalence  of  heart  failure  translates  into  significant  hospitalization  rates  and  associated  societal  costs.  About  6.4 million 
people  in  the  United  States  have  heart  failure  (approximately  half  with  reduced  ejection  fraction),  resulting  in  nearly  one  million 
hospital discharges with the primary diagnosis of heart failure and approximately 300,000 deaths each year. For people over 65 years 
of age, heart failure incidences approach 10 per 1000 and approximately 50% of people diagnosed with heart failure will die within 
5 years  of  diagnosis.  These  numbers  are  increasing  due  to  the  aging  of  the  U.S. population  and  an  increased  likelihood  of  survival 
following acute myocardial infarctions. 

The costs to society attributable to heart failure are high, especially as many chronic heart failure patients suffer repeated acute 
episodes.  Despite  currently  available  therapies,  readmission  rates  for  heart  failure  patients  remain  high.  In  general,  the  mortality 
following hospitalization for patients with heart failure is approximately 10% at 30 days, 22% at one year and 42% at 5 years, despite 
the availability of therapeutic alternatives for treatment of these patients. These poor outcomes in the setting of current therapies point 
to the need for novel therapeutics that may offer further reductions in morbidity and mortality. The annual cost of heart failure to the 
U.S. health care system is estimated to be $32 billion and is predicted to grow to almost $70 billion by the year 2030. Approximately 
70% of those costs are due to hospitalization, home health and physician care. In the U.S., Medicare is one of the largest payors for 
heart  failure  related  costs.  Approximately  50%  of  Medicare  beneficiaries  with  heart  failure  are  concentrated  in  the  top  20%  of the 
hospital referral regions in the U.S. New drug therapies that could reduce the number of hospitalizations could decrease the cost to the 
health care system.

CK-274

CK-274  is  a  novel,  oral,  small  molecule  cardiac  myosin  inhibitor  that  our  company  scientists  discovered  independent  of  our 
collaborations. CK-274 arose from an extensive chemical optimization program conducted with careful attention to therapeutic index 
and pharmacokinetic properties that may translate into best-in-class potential in clinical development. CK-274 was designed to reduce 
the hypercontractility that is associated with HCM. In preclinical models, CK-274 reduces myocardial contractility by binding directly 
to cardiac myosin at a distinct and selective allosteric binding site, thereby preventing myosin from entering a force producing state. 
CK-274  reduces  the  number  of  active  actin-myosin  cross  bridges  during  each  cardiac  cycle  and  consequently  reduces  myocardial 
contractility. This mechanism of action may be therapeutically effective in conditions characterized by excessive hypercontractility, 
such as HCM.

In preclinical models of cardiac function, CK-274 reduced cardiac contractility in a predictable dose and exposure dependent 
fashion.  In  preclinical  models  of  disease,  CK-274  reduced  compensatory  cardiac  hypertrophy  and  cardiac  fibrosis.  The  preclinical 
pharmacokinetics of CK-274 were characterized, evaluated and optimized for potential ease-of-use in the clinical setting. The initial 
focus of our development program for CK-274 will include an extensive characterization of its pharmacokinetics/pharmacodynamic 
(PK/PD)  relationship  as  has  been  a  hallmark  of  our  development  programs  in  muscle  pharmacology.  The  overall  development 
program  will  assess  the  potential  of  CK-274  to  improve  exercise  capacity  and  relieve  symptoms  in  patients  with  hyperdynamic 
ventricular contraction due to HCM.

CK-274: Clinical Development

We  are  conducting  a  Phase  1  double-blind,  randomized,  placebo-controlled,  multi-part,  single  and  multiple  ascending  dose 

clinical trial of CK-274 to assess the safety and tolerability, pharmacokinetics and pharmacodynamics of CK-274 in healthy subjects. 

CK-274: HCM Commercial Market

HCM  is  the  most  common  inherited  cardiovascular  disorder.  HCM  is  a  disease  in  which  the  heart  muscle  (myocardium) 
becomes abnormally thick (hypertrophied). The thickening of cardiac muscle leads to the inside of the left ventricle becoming smaller 
and stiffer, and thus the ventricle becomes less able to relax and fill with blood. This ultimately limits the heart’s pumping function, 
resulting in symptoms including chest pain, dizziness, shortness of breath, or fainting during physical activity. A subset of patients 
with HCM are at high risk of progressive disease which can lead to atrial fibrillation, stroke and death due to arrhythmias. There are 
no current medical treatments that directly address the hypercontractility that underlies HCM.

Skeletal Muscle Contractility Program

Our skeletal muscle contractility program is focused on the activation of the skeletal sarcomere, the basic unit of skeletal muscle 
contraction. The skeletal sarcomere is a highly ordered cytoskeletal structure composed of skeletal muscle myosin, actin, and a set of 
regulatory  proteins,  which  include  the  troponins  and  tropomyosin.  This  program  leverages  our  expertise  developed  in  our  ongoing 
discovery and development of cardiac sarcomere activators, including the cardiac myosin activator, omecamtiv mecarbil.

We  believe  that  our  skeletal  sarcomere  activators  may  lead  to  new  therapeutic  options  for  diseases  and  medical  conditions 
associated with neuromuscular dysfunction and potentially also conditions associated with aging and muscle weakness and wasting.  
The clinical effects of muscle weakness and wasting, fatigue and loss of mobility can range from decreased quality of life to, in some 
instances,  life-threatening  complications.  By  directly  improving  skeletal  muscle  function,  a  small  molecule  activator  of  the  skeletal 
sarcomere  potentially  could  enhance  functional  performance  and  quality  of  life  in  patients  suffering  from  diseases  or  medical 

7

conditions associated with skeletal muscle weakness or wasting, such as ALS, SMA, COPD or sarcopenia (general frailty associated 
with aging).

Reldesemtiv

Reldesemtiv  selectively  activates  the  fast  skeletal  muscle  troponin  complex  in  the  sarcomere  by  increasing  its  sensitivity  to 
calcium, leading to an increase in skeletal muscle contractility. Reldesemtiv has demonstrated pharmacological activity in preclinical 
models and evidence of potentially clinically relevant pharmacodynamic effects in humans. The FDA has granted reldesemtiv orphan 
drug designation for the potential treatment of SMA. 

Astellas Strategic Alliance 

Our  strategic  alliance  with  Astellas  to  advance  novel  therapies  for  diseases  and  medical  conditions  associated  with  muscle 
impairment and weakness is governed by the Astellas Agreement. We initially exclusively licensed to Astellas rights to co-develop 
and potentially co-commercialize reldesemtiv and other FSTAs 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. Subsequently, we and Astellas expanded the strategic alliance to include certain neuromuscular indications, 
including SMA, for reldesemtiv and other FSTAs and to advance reldesemtiv into Phase 2 clinical development, initially in SMA. In 
2016, we and Astellas further expanded the strategic alliance to include the development of reldesemtiv for the potential treatment of 
ALS, as well as the possible development in ALS of other FSTAs previously licensed by us to Astellas, and granted Astellas an option 
for  a  global  collaboration  for  the  development  and  commercialization  of  our  first-generation  FSTA,  tirasemtiv  (the  “Option  on 
Tirasemtiv”).

The  strategic  alliance  with  Astellas  includes  a  joint  research  program  focused  on  the  discovery  of  additional  next-generation 

skeletal muscle activators, including sponsored research at Cytokinetics. This research program has been extended through 2019.

We  have  options  to  conduct  early-stage  development  for  certain  agreed  indications  at  our  initial  expense,  subject  to 
reimbursement  if  development  continues  under  the  strategic  alliance;  to  co-promote  collaboration  products  containing  FSTAs  for 
neuromuscular indications in the U.S., Canada and Europe; and to co-promote other collaboration products in the U.S. and Canada. 
Astellas will reimburse us for certain expenses associated with our co-promotion activities. 

Astellas is primarily responsible for the development of reldesemtiv in ALS, but we are conducting FORTITUDE-ALS and will 
share in the operational responsibility for subsequent clinical trials. Subject to specified guiding principles, decision making will be by 
consensus, subject to escalation and, if necessary, Astellas’ final decision-making authority on the development (including regulatory 
affairs), manufacturing, medical affairs and commercialization of reldesemtiv and other FSTAs in ALS. We and Astellas share equally 
the costs of developing reldesemtiv in ALS for potential registration and marketing authorization in the U.S. and Europe, provided that 
(i) Astellas has agreed to solely fund Phase 2 development costs of reldesemtiv in ALS subject to a right to recoup our share of such 
costs plus a 100% premium on such amounts by reducing future milestone and royalty payments to us and (ii) we may defer (but not 
eliminate)  a  portion  of  our  co-funding  obligation  for  development  activities  after  Phase  2  for  up  to  18  months,  subject  to  certain 
conditions. We have the right to co-fund our share of such Phase 2 development costs on a current basis, in which case there would 
not be a premium due to Astellas.

Based on the achievement of pre-specified criteria, we may receive over $600.0 million in milestone payments relating to the 
development  and  commercial  launch  of  collaboration  products,  including  up  to  $112.0  million  (of  which  we  have  received  $17.0 
million)  relating  to  early  development  of  reldesemtiv  and  for  later-stage  development  and  commercial  launch  milestones  for 
reldesemtiv  in  non-neuromuscular  indications,  and  over  $100.0  million  in  development  and  commercial  launch  milestones  for 
reldesemtiv  in  each  of  SMA  and  other  neuromuscular  indications.  We  may  also  receive  up  to  $200.0  million  in  payments  for 
achievement of pre-specified sales milestones related to net sales of all collaboration products. 

If  Astellas  commercializes  any  collaboration  products,  we  will  also  receive  royalties  on  sales  of  such  collaboration  products, 
including royalties ranging from the high single digits to the high teens on sales of products containing reldesemtiv. We can co-fund 
certain  development  costs  for  reldesemtiv  and  other  compounds  in  exchange  for  increased  milestone  payments  and  royalties;  such 
royalties may increase under certain scenarios to exceed twenty percent. In addition to the foregoing development, commercial launch 
and  sales  milestones,  we  may  also  receive  payments  for  the  achievement  of  pre-specified  milestones  relating  to  the  joint  research 
program.

Astellas generally has discretion to elect whether to pursue or abandon the development of reldesemtiv and other collaboration 
products, in whole or in part. Astellas may terminate our strategic alliance in whole or in part for any reason upon six months’ prior 
notice at any time following expiration of the strategic alliance’s research term, which will expire December 31, 2019.

Reldesemtiv: Clinical Development 

SMA: In June 2018, we announced data from a hypothesis-generating, Phase 2 double-blind, randomized, placebo-controlled 
clinical study in patients with SMA which was designed to determine potential pharmacodynamic effects of a suspension formulation 
of reldesemtiv following 8 weeks of oral dosing in each of two cohorts of 36 patients with Type II, Type III, or Type IV disease were 

8

presented  at  the  2018  Annual  Cure  SMA  Conference  in  Dallas.  Secondary  objectives  were  to  evaluate  the  safety,  tolerability  and 
pharmacokinetics  of  reldesemtiv.  The  study  showed  statistically  significant  concentration-dependent  increases  in  changes  from 
baseline  in  Six  Minute  Walk  Distance  (“6MWD”),  a  sub-maximal  exercise  test  of  aerobic  capacity  and  endurance.  The  study  also 
showed  statistically  significant  increases  for  Maximal  Expiratory  Pressure  (“MEP”),  a  measure  of  strength  of  respiratory  muscles. 
Other assessments, including the Hammersmith Functional Motor Score - Extended, Revised Upper Limb Module, Timed Up-and-Go, 
Forced Vital Capacity, and the SMA Health Index (“SMA-HI”), a patient reported outcome measure (“PROM”) developed to comply 
with FDA standards for PROMs, did not demonstrate differences between reldesemtiv versus placebo. Adverse events were similar 
between groups receiving reldesemtiv and placebo. 

Additional results presented at the 2018 Muscle Study Group Scientific Meeting in Oxford, U.K. showed sustained increases in 
6MWD and MEP four weeks after discontinuation of study drug (i.e., follow-up). A post-hoc analysis also showed that changes from 
baseline  in  the  6MWD  at  450  mg  twice  daily  were  significantly  correlated  with  changes  from  baseline  on  certain  domains  of  the 
SMA-HI intended to reflect improved endurance, especially Fatigue and Activity Participation. Decreases in SMA-HI scores reflect 
reduced disease burden as measured by that PROM, indicating that as 6MWD increases, disease burden assessed by that domain of the 
SMA-HI is reduced.

In  January  2019,  we  announced  that  we  received  feedback  from  the  FDA  that  the  Six  Minute  Walk  Test  (6MWT)  is  an 
acceptable primary efficacy endpoint for a potential registration program for reldesemtiv in patients with SMA who have maintained 
ambulatory function. The FDA also recommended adding a global function scale as a secondary endpoint. 

ALS: In collaboration with Astellas, we are conducting FORTITUDE-ALS. This trial was designed to enroll approximately 450 
eligible ALS patients to be randomized (1:1:1:1) to receive either 150 mg, 300 mg or 450 mg of reldesemtiv or placebo dosed orally 
twice daily for 12 weeks. The primary efficacy endpoint of FORTITUDE-ALS is the change from baseline in the percent predicted 
slow vital capacity (“SVC”) at 12 weeks. Secondary endpoints include slope of the change from baseline in the mega-score of muscle 
strength measured by hand held dynamometry (“HHD”) and handgrip dynamometry in patients on reldesemtiv; change from baseline 
in  the  ALS  Functional  Rating  Scale  –  Revised  (“ALSFRS-R”);  incidence  and  severity  of  treatment-emergent  adverse  events 
(“TEAEs”);  and  plasma  concentrations  of  reldesemtiv  at  the  sampled  time  points  during  the  study.  Exploratory  endpoints  will  be 
measured including the effect of reldesemtiv versus placebo on self-assessments of respiratory function made at home by the patient 
with help as needed by the caregiver; disease progression through quantitative measurement of speech production characteristics over 
time; disease progression through quantitative measurement of handwriting abilities over time; and change from baseline in quality of 
life  (as  measured  by  the  ALSAQ-5)  in  patients  on  reldesemtiv.  In  November  2018,  we  announced  completion  of  enrollment  in 
FORTITUDE-ALS. We expect results from this trial in the second quarter of 2019.

COPD:  Astellas,  in  collaboration  with  Cytokinetics,  conducted  a  Phase  2  clinical  trial  of  reldesemtiv  in  patients  with  COPD 
designed to assess the effect of reldesemtiv on physical function in patients with COPD. In October 2018, we announced that this trial 
did  not  meet  the  primary  endpoint  and  did  not  demonstrate  a  statistically  significant  treatment  difference  in  any  of  the  secondary 
endpoints. Adverse events were similar between groups receiving reldesemtiv and placebo.

Frailty: Astellas, in collaboration with Cytokinetics, conducted a Phase 1b clinical trial of reldesemtiv in elderly subjects with 
limited  mobility.  In  October  2018,  we  announced  that  an  interim  analysis  of  this  study  had  been  conducted,  the  Independent  Data 
Monitoring  Committee  for  this  trial  determined  that  the  pre-defined  criteria  for  lack  of  efficacy  of  reldesemtiv  had  been  met  and 
Astellas had notified investigators to halt further enrollment in the trial.

The clinical trials program for reldesemtiv may proceed for several years, and we may not generate any revenues or material net 
cash flows from sales of this drug candidate until the program is successfully completed, regulatory approval is achieved, and the drug 
is commercialized. We cannot predict if or when this may occur. 

Our expenditures will increase if Astellas terminates development of reldesemtiv or related compounds and we elect to develop 
them  independently,  or  if  we  conduct  early-stage  development  for  certain  agreed  indications  at  our  initial  expense,  subject  to 
reimbursement if development continues under the collaboration. 

CK-3762601

In  October  2018,  we  announced  that  we  and  Astellas  are  advancing  CK-3762601  (“CK-601”),  a  next-generation  FSTA,  into 
IND-enabling studies, which triggered a $2 million milestone payment from Astellas to us. CK-601 was designed in a joint research 
program conducted by the companies’ scientists to have different pharmacokinetics and physicochemical properties than reldesemtiv 
which  may  inform  its  development  for  the  treatment  of  diseases  and  conditions  associated  with  both  neuromuscular  and  non-
neuromuscular etiology and pathogenesis.

Ongoing Research in Skeletal Muscle Activators 

Our research program with Astellas has been extended through 2019. Our research on the direct activation of skeletal muscle 
continues in two areas. We are conducting translational research in preclinical models of disease and muscle function with FSTAs to 
explore  the  potential  clinical  applications  of  this  novel  mechanism  in  diseases  or  conditions  associated  with  skeletal  muscle 
dysfunction.  We  also  intend  to  conduct  preclinical  research  on  other  chemically  and  pharmacologically  distinct  mechanisms  to 
activate the skeletal sarcomere. 

Commercial Market for SMA: SMA is a severe neuromuscular disease that occurs in 1 in every 6,000 to 10,000 live births each 
year resulting in a prevalence of 10,000 to 15,000 patients in the U.S. and is one of the most common fatal genetic disorders. SMA 
manifests in various degrees of severity as progressive muscle weakness resulting in respiratory and mobility impairment. There are 
four types of SMA, distinguished by the time of the initial onset of muscle weakness and the severity of related symptoms: Type I 
(severe), Type II (intermediate), Type III (juvenile) and Type IV (adult onset). Life expectancy and disease severity varies by type of 
SMA from Type I, who have the worst prognosis and a life expectancy of approximately two years from birth, to Type IV, who have a 
normal life span but with gradual weakness in the proximal muscles of the extremities resulting in mobility issues. Type II, III and IV 
patients are often characterized by their ambulatory status as it is an important driver of clinical decisions and care and constitute 50% 
of  the  incident  patient  population  but  as  much  as  90%  of  the  prevalent  patient  population.  Few  treatment  options  exist  for  these 
patients,  resulting  in  a  high  unmet  need  for  new  therapeutic  options  to  ameliorate  symptoms,  improve  muscle  function  and  modify 
disease progression. 

Commercial  Market  for  ALS:  Limited  options  exist  for  the  treatment  of  patients  with  ALS,  which  affects  as  many  as  30,000 
Americans, with an estimated 5,600 new cases diagnosed each year in the U.S. Based on our primary market research, the per capita 
prevalence and incidence appears similar in the major European markets. ALS is 20% more common in men than women; however, 
with increasing age, the prevalence becomes more equal between men and women. The life expectancy of an ALS patient averages 
two to five years from the time of diagnosis, mostly due to respiratory issues. Of the patients diagnosed with ALS, 5 to 10% have a 
family history of the disease (familial ALS) and remaining 90 to 95% have the sporadic form. The majority of patients with ALS in 
the  U.S.  and  Europe  receive  treatment  at  a  concentrated  number  of  multidisciplinary  centers  that  specialize  in  the  unique  needs  of 
these patients. In the U.S., there are approximately 150 ALS multidisciplinary clinics, according to either the ALS Association or the 
Muscular  Dystrophy  Association.  For  most  patients  with  ALS,  death  is  usually  due  to  respiratory  failure  because  of  diminished 
strength in the skeletal muscles responsible for breathing. We believe that there is an urgent need for novel therapies to address the 
unmet medical issues of this patient population which could be addressed by a small, targeted sales force. 

Other  Commercial  Markets  for  Skeletal  Muscle  Activators:  We  continue  to  evaluate  potential  commercial  markets  for  other 

potential indications for skeletal muscle activators.

Tirasemtiv

In November 2017, we announced that VITALITY-ALS, a Phase 3 clinical trial of tirasemtiv in patients with ALS, did not meet 
its primary endpoint of change from baseline in SVC and we suspended development of tirasemtiv. After consulting with an advisory 
board of ethicists, patient advocates, trial investigators and experts in pre-approval access to assess whether and how best to continue 
providing tirasemtiv to those people living with ALS participating in VIGOR-ALS, an open-label extension clinical trial designed to 
assess  the  long-term  safety  and  tolerability  of  tirasemtiv  in  patients  with  ALS,  we  closed  VIGOR-ALS  and  established  a  Managed 
Access Program for patients previously enrolled in VIGOR-ALS to remain on tirasemtiv.

Beyond Muscle Contractility

We developed preclinical expertise in the mechanics of skeletal, cardiac and smooth muscle that extends from proteins to tissues 
to intact animal models. Our translational research in muscle contractility has enabled us to better understand the potential impact of 
small molecule compounds that increase skeletal or cardiac muscle contractility and to apply those findings to the further evaluation of 
our drug candidates in clinical populations. In addition to contractility, other major functions of muscle play a role in certain diseases 
that could benefit from novel mechanism treatments. Accordingly, our knowledge of muscle contractility may serve as an entry point 
to the discovery of novel treatments for disorders involving muscle functions other than muscle contractility. We are leveraging our 
current  understandings  of  muscle  biology  to  investigate  new  ways  of  modulating  these  other  aspects  of  muscle  function  for  other 
potential therapeutic applications.

Intellectual Property

Our  policy  is  to  seek  patent  protection  for  the  technologies,  inventions  and  improvements  that  we  develop  that  we  consider 
important  to  the  advancement  of  our  business.  As  of  December 31,  2018,  we  owned,  co-owned  or  licensed  96  issued  U.S. patents, 
over 360 issued patents in various foreign jurisdictions, and over 225 additional pending U.S. and foreign patent applications. We also 
rely  on  trade  secrets,  technical  know-how  and  continuing  innovation  to  develop  and  maintain  our  competitive  position.  Our 
commercial success will depend on obtaining and maintaining patent protection and trade secret protection for our drug candidates and 

10

technologies  and  our  successfully  defending  these  patents  against  third-party  challenges.  We  will  only  be  able  to  protect  our 
technologies from unauthorized use by third parties to the extent that valid and enforceable patents cover them or we maintain them as 
trade secrets.

With regard to our drug candidates directed to muscle biology targets, we have a U.S. patent covering omecamtiv mecarbil and 
U.S. patents  covering  our  skeletal  muscle  sarcomere  activators  including,  but  not  limited  to  reldesemtiv,  which  expire  in  2027 and 
2031, respectively, unless extended or otherwise adjusted. We also have issued patents in various foreign jurisdictions and additional 
U.S. and  foreign  patent  applications  pending  for  these  drug  candidates.  It  is  not  known  or  determinable  whether  other  patents  will 
issue from any of our other pending applications or what the expiration dates would be for any other patents that do issue.

Our  drug  candidates  are  still  in  clinical  development  and  have  not  yet  been  approved  by  the  FDA.  If  any  of  these  drug 
candidates are approved, then pursuant to federal law, we may apply for an extension of the U.S. patent term for one patent covering 
the approved drug, which could extend the term of the applicable patent by up to a maximum of five additional years.

The degree of future protection of our proprietary rights is uncertain because legal means may not adequately protect our rights 
or  permit  us  to  gain  or  keep  our  competitive  advantage.  Due  to  evolving  legal  standards  relating  to  the  patentability,  validity  and 
enforceability of patents covering pharmaceutical inventions and the claim scope of these patents, our ability to enforce our existing 
patents  and  to  obtain  and  enforce  patents  that  may  issue  from  any  pending  or  future  patent  applications  is  uncertain  and  involves 
complex legal, scientific and factual questions. The standards that the U.S. Patent and Trademark Office and its foreign counterparts 
use  to  grant  patents  are  not  always  applied  predictably  or  uniformly  and  are  subject  to  change.  To  date,  no  consistent  policy  has 
emerged  regarding  the  breadth  of  claims  allowed  in  biotechnology  and  pharmaceutical  patents.  Thus,  we  cannot  be  sure  that  any 
patents will issue from any pending or future patent applications owned by, co-owned, or licensed to us. Even if patents do issue, we 
cannot be sure that the claims of these patents will be held valid or enforceable by a court of law, will provide us with any significant 
protection against competitive products, or will afford us a commercial advantage over competitive products. For example:

•

•

•

•

•

•

•

•

we  or  our  licensors  might  not  have  been  the  first  to  make  the  inventions  covered  by  each  of  our  pending  patent 
applications or issued patents;

we  or  our  licensors  might  not  have  been  the  first  to  file  patent  applications  for  the  inventions  covered  by  our  pending 
patent applications or issued patents;

others  may  independently  develop  similar  or  alternative  technologies  or  duplicate  any  of  our  technologies  without 
infringing our intellectual property rights;

some or all of our or our licensors’ pending patent applications may not result in issued patents or the claims that issue 
may be narrow in scope and not provide us with competitive advantages;

our  and  our  licensors’  issued  patents  may  not  provide  a  basis  for  commercially  viable  drugs  or  therapies  or  may  be 
challenged and invalidated by third parties;

our or our licensors’ patent applications or patents may be subject to interference, post-grant proceedings, opposition or 
similar legal and administrative proceedings that may result in a reduction in their scope or their loss altogether;

we may not develop additional proprietary technologies or drug candidates that are patentable; or

the patents of others may prevent us or our partners from discovering, developing or commercializing our drug candidates.

The defense and prosecution of intellectual property infringement suits, interferences, post-grant proceedings, oppositions and 
related legal and administrative proceedings are costly, time-consuming to pursue and divert resources. The outcome of these types of 
proceedings is uncertain and could significantly harm our business.

Our ability to commercialize drugs depends on our ability to use, manufacture and sell those drugs without infringing the patents 
or other proprietary rights of third parties. U.S. and foreign issued patents and pending patent applications owned by third parties exist 
that may be relevant to the therapeutic areas and chemical compositions of our drug candidates. While we are aware of certain relevant 
patents and patent applications owned by third parties, there may be issued patents or pending applications of which we are not aware 
that  could  cover  our  drug  candidates.  Because  patent  applications  are  often  not  published  immediately  after  filing,  there  may  be 
currently pending applications, unknown to us, which could later result in issued patents that our activities with our drug candidates 
could infringe.

The  development  of  our  drug  candidates  and  the  commercialization  of  any  resulting  drugs  may  be  impacted  by  patents  of 
companies engaged in competitive programs with significantly greater resources. This could result in the expenditure of significant 
legal fees and management resources.

We also rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or 
obtainable. However, trade secrets are often difficult to protect, especially outside of the United States. While we believe that we use 
reasonable efforts to protect our trade secrets, our employees, consultants, contractors, partners and other advisors may unintentionally 
or willfully disclose our trade secrets to competitors. Enforcing a claim that a third party had illegally obtained and is using our trade 

11

secrets would be expensive and time-consuming, and the outcome would be unpredictable. Even if we are able to maintain our trade 
secrets as confidential, our competitors may independently develop information that is equivalent or similar to our trade secrets.

We seek to protect our intellectual property by requiring our employees, consultants, contractors and other advisors to execute 
nondisclosure and invention assignment agreements upon commencement of their employment or engagement, through which we seek 
to protect our intellectual property. Agreements with our employees also preclude them from bringing the proprietary information or 
materials  of  third  parties  to  us.  We  also  require  confidentiality  agreements  or  material  transfer  agreements  from  third  parties  that 
receive our confidential information or materials.

For  further  details  on  the  risks  relating  to  our  intellectual  property,  please  see  the  risk  factors  under  Item 1A  of  this  report, 
including,  but  not  limited  to,  the  risk  factors  entitled  “Our  success  depends  substantially  upon  our  ability  to  obtain  and  maintain 
intellectual  property  protection  relating  to  our  drug  candidates  and  research  technologies”  and  “If  we  are  sued  for  infringing third-
party intellectual property rights, it will be costly and time-consuming, and an unfavorable outcome would have a significant adverse 
effect on our business.”

Government Regulation

The  FDA  and  comparable  regulatory  agencies  in  state  and  local  jurisdictions  and  in  foreign  countries  impose  substantial 
requirements upon the clinical development, manufacture, marketing and distribution of drugs. These agencies and other federal, state 
and local entities regulate research and development activities and the testing, manufacture, quality control, labeling, storage, record 
keeping, approval, advertising and promotion of our drug candidates and drugs.

In the United States, the FDA regulates drugs under the Federal Food, Drug and Cosmetic Act and implementing regulations. 

The process required by the FDA before our drug candidates may be marketed in the United States generally involves the following:

•

•

•

•

•

•

completion of extensive preclinical laboratory tests, preclinical animal studies and formulation studies, all performed in 
accordance with the FDA’s good laboratory practice regulations;

submission to the FDA of an investigational new drug application (“IND”), which must become effective before clinical 
trials may begin;
performance of adequate and well-controlled clinical trials to establish the safety and efficacy of the drug candidate for 
each proposed indication in accordance with good clinical practices;
submission  of  a  new  drug  application  (“NDA”)  to  the  FDA,  which  must  usually  be  accompanied  by  payment  of  a 
substantial user fee;
satisfactory completion of an FDA preapproval inspection of the manufacturing facilities at which the product is produced 
to assess compliance with current good manufacturing practice (“cGMP”) regulations and FDA audits of select clinical 
investigator sites to assess compliance with good clinical practices (“GCP”); and
FDA review and approval of the NDA prior to any commercial marketing, sale or shipment of the drug.

Similar  regulatory  procedures  generally  apply  in  countries  outside  of  the  United  States.  This  testing  and  approval  process 
requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our drug candidates will be 
granted on a timely basis, if at all.

Non-clinical tests include laboratory evaluation of product chemistry, formulation and stability, and studies to evaluate toxicity 
and pharmacokinetics in animals. The results of non-clinical tests, together with manufacturing information and analytical data, are 
submitted  as  part  of  an  IND  application  to  the  FDA.  The  IND  automatically  becomes  effective  30 days  after  receipt  by  the  FDA, 
unless  the  FDA,  within  the  30-day  period,  raises  concerns  or  questions  about  the  conduct  of  the  proposed  clinical  trial,  including 
concerns that human research subjects may be exposed to unreasonable health risks. In such a case, the IND sponsor and the FDA 
must resolve any outstanding concerns before the clinical trial can begin. Our submission of an IND or a foreign equivalent, or those 
of our collaborators, may not result in authorization from the FDA or its foreign equivalent to commence a clinical trial. A separate 
submission to an existing IND must also be made for each successive clinical trial conducted during product development. Further, an 
independent institutional review board (“IRB”) or its foreign equivalent for each medical center proposing to conduct the clinical trial 
must review and approve the plan for any clinical trial before it commences at that center and it must monitor the clinical trial until 
completed.  The  FDA,  the  IRB  or  their  foreign  equivalents,  or  the  clinical  trial  sponsor  may  suspend  a  clinical  trial  at  any  time  on 
various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk.

Clinical Trials.     For purposes of an NDA or equivalent submission and approval, clinical trials are typically conducted in the 

following three sequential phases, which may overlap:

•

Phase 1:     Phase 1 trials include the initial introduction of a drug candidate into humans. These studies may be conducted 
in patients, but are usually conducted in healthy volunteer subjects. These studies are designed to determine the metabolic 
and  pharmacologic  actions  of  the  drug  candidate  in  humans,  the  side  effects  associated  with  increasing  doses,  and,  if 
possible,  to  gain  early  evidence  on  effectiveness.  During  Phase  1,  sufficient  information  about  the  drug  candidate’s 
pharmacokinetics  and  pharmacological  effects  should  be  obtained  to  permit  the  design  of  well-controlled,  scientifically 
valid, Phase 2 trials.

12

•

•

Phase 2:     Phase 2 trials include the early controlled clinical studies conducted to obtain some preliminary data on the 
effectiveness of the drug candidate for a particular indication or indications in patients with the disease or condition. This 
phase  of  testing  also  helps  determine  the  common  short-term  side  effects  and  risks  associated  with  the  drug  candidate. 
These clinical trials are generally conducted in a limited patient population to identify possible adverse effects and safety 
risks, to make an initial determination of potential efficacy of the drug candidate for specific targeted indications and to 
determine dose tolerance and optimal dosage. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain 
information  prior  to  beginning  larger  and  more  expensive  Phase 3  clinical  trials.  Phase  2a  clinical  trials  generally  are 
designed to study the pharmacokinetic or pharmacodynamic properties and to conduct a preliminary assessment of safety 
of the drug candidate over a measured dose response range. In some cases, a sponsor may decide to conduct a Phase 2b 
clinical  trial,  which  is  a  second,  typically  larger,  confirmatory  Phase 2  trial  that  could,  if  positive  and  accepted  by  a 
regulatory authority, support approval of a drug candidate.
Phase 3:     If the Phase 2 clinical trials demonstrate that a dose range of the drug candidate is potentially effective and has 
an  acceptable  safety  profile,  Phase 3  clinical  trials  are  then  undertaken  in  large  patient  populations  to  further  evaluate 
dosage, to provide substantial evidence of clinical efficacy and to further test for safety in an expanded and diverse patient 
population at multiple, geographically dispersed clinical trial sites. Phase 3 trials are also intended to provide an adequate 
basis for extrapolating the results to the general population and transmitting that information in the drug labeling. Phase 3 
studies usually include several hundred to several thousand people, and are usually longer in duration than Phase 2 trials.

At any time during the conduct of a clinical trial, the FDA or a foreign equivalent can impose a clinical hold on the trial if it 
believes the trial is unsafe or that the protocol is clearly deficient in design in meeting its stated objectives, which requires the conduct 
of  the  trial  to  cease  until  the  clinical  hold  is  removed.  In  some  cases,  the  FDA  or  foreign  equivalent  may  condition  approval  of 
marketing approval for a drug candidate on the sponsor’s agreement to conduct additional clinical trials to further assess the drug’s 
safety and effectiveness after marketing approval, known as Phase 4 clinical trials.

The  clinical  trials  we  conduct  for  our  drug  candidates,  both  before  and  after  approval,  and  the  results  of  those  trials,  are 
generally required to be included in a clinical trials registry database that is available and accessible to the public via the internet. A 
failure by us to properly participate in the clinical trial database registry could subject us to significant civil monetary penalties.

Health  care  providers  in  the  United  States,  including  research  institutions  from  which  we  or  our  partners  obtain  patient 
information,  are  subject  to  privacy  rules  under  the  Health  Insurance  Portability  and  Accountability  Act  of  1996  and  state  and  local 
privacy laws. In the European Union, these entities are subject to the Directive 95/46-EC of the European Parliament on the protection 
of individuals with regard to the processing of personal data and individual European Union member states implementing additional 
legislation. The General Data Protection Regulation (EU) 2016/679 is a regulation in EU law on data protection and privacy for all 
individuals  within  the  EU  and  the  European  Economic  Area.  Other  countries  have  similar  privacy  legislation.  We  could  face 
substantial  penalties  if  we  knowingly  receive  individually  identifiable  health  information  from  a  health  care  provider  that  has  not 
satisfied the applicable privacy laws. In addition, certain privacy laws and genetic testing laws may apply directly to our operations 
and/or those of our partners and may impose restrictions on the use and dissemination of individuals’ health information and use of 
biological samples.

New Drug/Marketing Approval Application.     The results of drug candidate development, preclinical testing and clinical trials 
are submitted to the FDA as part of an NDA. The NDA also must contain extensive manufacturing information. In addition, the FDA 
may require that a proposed Risk Evaluation and Mitigation Strategy, also known as a REMS, be submitted as part of the NDA if the 
FDA determines that it is necessary to ensure that the benefits of the drug outweigh its risks. Similar, and in some cases additional, 
requirements apply in foreign jurisdictions for marketing approval applications for drugs in those jurisdictions. The FDA may refer the 
NDA  to  an  advisory  committee  for  review,  evaluation  and  recommendation  as  to  whether  the  application  should  be  approved.  The 
FDA often, but not always, follows the advisory committee’s recommendations. The FDA may deny approval of an NDA by issuing a 
complete response letter if the applicable regulatory criteria are not satisfied, or it may require additional clinical data, including data 
in a pediatric population, or an additional Phase 3 clinical trial or impose other conditions that must be met in order to secure final 
approval for an NDA.

Even if such data are submitted, the FDA may ultimately decide that the NDA does not satisfy the criteria for approval. Data 
from clinical trials are not always conclusive and the FDA may interpret data differently than we or our partners do. Once issued, the 
FDA or foreign equivalent may withdraw a drug approval if ongoing regulatory requirements are not met or if safety problems occur 
after  the  drug  reaches  the  market.  In  addition,  the  FDA  or  its  foreign  counterparts  may  require  further  testing,  including  Phase 4 
clinical  trials,  and  surveillance  or  restrictive  distribution  programs  to  monitor  the  effect  of  approved  drugs  which  have  been 
commercialized. The FDA and its foreign counterparts have the power to prevent or limit further marketing of a drug based on the 
results  of  these  post-marketing  programs.  Drugs  may  be  marketed  only  for  the  approved  indications  and  in  accordance  with  the 
provisions  of  the  approved  label.  Further,  if  there  are  any  modifications  to  a  drug,  including  changes  in  indications,  labeling  or 
manufacturing  processes  or  facilities,  we  may  be  required  to  submit  and  obtain  prior  FDA  approval  of  a  new  NDA  or  NDA 
supplement, or the foreign equivalent, which may require us to develop additional data or conduct additional preclinical studies and 
clinical trials.

Satisfaction of FDA regulations and requirements or similar regulations and requirements of state, local and foreign regulatory 
agencies typically takes several years. The actual time required may vary substantially based upon the type, complexity and novelty of 
the drug candidate or disease. Typically, if a drug candidate is intended to treat a chronic disease, as is the case with some of our drug 
candidates, safety and efficacy data must be gathered over an extended period of time. Government regulation may delay or prevent 
marketing  of  drug  candidates  for  a  considerable  period  of  time  and  impose  costly  procedures  upon  our  activities.  The  FDA  or  any 
other regulatory agency may not grant approvals for new indications for our drug candidates on a timely basis, if at all. Even if a drug 
candidate  receives  regulatory  approval,  the  approval  may  be  significantly  limited  to  specific  disease  states,  patient  populations  and 
dosages or restrictive distribution programs. Further, even after regulatory approval is obtained, later discovery of previously unknown 
problems  with  a  drug  may  result  in  restrictions  on  the  drug  or  even  complete  withdrawal  of  the  drug  from  the  market.  Delays  in 
obtaining, or failures to obtain, regulatory approvals for any of our drug candidates would harm our business. In addition, we cannot 
predict what future U.S. or foreign governmental regulations may be implemented.

Orphan Drug Designation.     Some jurisdictions, including the United States, may designate drugs for relatively small patient 
populations as orphan drugs. The FDA grants orphan drug designation to drugs intended to treat a rare disease or condition, which is 
generally a disease or condition that affects fewer than 200,000 individuals in the United States. 

An  FDA  orphan  drug  designation  does  not  shorten  the  duration  of  the  regulatory  review  and  approval  process.  If  a  drug 
candidate that has an orphan drug designation receives the first FDA marketing approval for the indication for which the designation 
was  granted,  then  the  approved  drug  is  entitled  to  orphan  drug  exclusivity.  This  means  that  the  FDA  may  not  approve  another 
company’s application to market the same drug for the same indication for a period of seven years, except in certain circumstances, 
such as a showing of clinical superiority to the drug with orphan exclusivity or if the holder of the orphan drug designation cannot 
assure the availability of sufficient quantities of the orphan drug to meet the needs of patients with the disease or condition for which 
the designation was granted. Competitors may receive approval of different drugs or biologics for the indications for which the orphan 
drug has exclusivity.

Special  Protocol  Assessment.    A  sponsor  may  request  a  Special  Protocol  Assessment,  or  SPA,  agreement  with  FDA  on  the 
Phase 3 clinical trial protocol design and analysis that will form the primary basis of an efficacy claim. Even if the FDA agrees to the 
design, execution and analyses proposed in protocols reviewed under the SPA process, the FDA may revoke or alter its agreement if 
public health concerns emerge that were unrecognized at the time of the SPA agreement, or a substantial scientific issue essential to 
determining safety or efficacy is identified after testing has begun. An SPA does not guarantee that an NDA will be approved.

Fast Track Designation.     Fast track is a process designed by the FDA to facilitate the development and expedite the review of 
drugs  to  treat  serious  diseases  and  fill  an  unmet  medical  need.  Although  fast  track  designation  does  not  affect  the  standards  for 
approval,  the  benefits  of  this  designation  include  scheduled  meetings  to  seek  FDA  input  into  development  plans,  the  option  of 
submitting an NDA in sections rather than all components simultaneously, and the potential eligibility for priority review if supported 
by clinical data.

Other Regulatory Requirements.     Any drugs manufactured or distributed by us or our partners pursuant to FDA approvals or 
their  foreign  counterparts  are  subject  to  continuing  regulation  by  the  applicable  regulatory  authority,  including  recordkeeping 
requirements and reporting of adverse experiences associated with the drug. Drug manufacturers and their subcontractors are required 
to  register  their  establishments  with  the  FDA  and  other  applicable  regulatory  authorities,  and  are  subject  to  periodic  unannounced 
inspections  by  these  regulatory  authorities  for  compliance  with  ongoing  regulatory  requirements,  including  cGMPs,  which  impose 
certain procedural and documentation requirements upon us and our third-party manufacturers. Failure to comply with the statutory 
and regulatory requirements can subject a manufacturer to possible legal or regulatory action, such as warning letters, suspension of 
manufacturing, seizure of product, injunctive action or possible civil penalties. We cannot be certain that we or our present or future 
third-party manufacturers or suppliers will be able to comply with the cGMP regulations and other ongoing FDA and other regulatory 
requirements. If our present or future third-party manufacturers or suppliers are not able to comply with these requirements, the FDA 
or  its  foreign  counterparts  may  halt  our  or  our  partners’  clinical  trials,  require  us  to  recall  a  drug  from  distribution,  or  withdraw 
approval of the NDA for that drug.

For further details on the risks relating to government regulation of our business, please see the risk factors under Item 1A of 
this report, including, but not limited to, the risk factor entitled “The regulatory approval process is expensive, time-consuming and 
uncertain and may prevent our partners or us from obtaining approvals to commercialize some or all of our drug candidates.”

Competition

We  compete  in  the  segments  of  the  pharmaceutical,  biotechnology  and  other  related  markets  that  address  neuromuscular  and 
cardiovascular diseases and other diseases relating to muscle dysfunction, each of which is highly competitive. We face significant 
competition  from  most  pharmaceutical  companies  and  biotechnology  companies  that  are  also  researching  and  selling  products 
designed  to  address  cardiovascular  diseases  and  diseases  and  medical  conditions  associated  with  skeletal  muscle  weakness  and 
wasting. Many of our competitors have significantly greater financial, manufacturing, marketing and drug development resources than 
we  do.  Large  pharmaceutical  companies  in  particular  have  extensive  experience  in  clinical  testing  and  in  obtaining  regulatory 
approvals for drugs. These companies also have significantly greater research capabilities than we do. In addition, many universities 

14

and private and public research institutes are active in research of neuromuscular and cardiovascular diseases and other diseases where 
there is muscle dysfunction, some in direct competition with us.

We believe that our ability to successfully compete will depend on, among other things:
•

our drug candidates’ efficacy, safety and tolerability;

•

•

•

•

•

•

•

•

•

•

•

•

the speed and cost-effectiveness with which we develop our drug candidates;

the selection of suitable indications for which to develop our drug candidates;

the successful completion of clinical development and laboratory testing of our drug candidates;

the timing and scope of any regulatory approvals we or our partners obtain for our drug candidates;

our or our partners’ ability to manufacture and sell commercial quantities of our approved drugs to meet market demand;

acceptance of our drugs by physicians and other health care providers;

the willingness of third-party payors to provide reimbursement for the use of our drugs;

our ability to protect our intellectual property and avoid infringing the intellectual property of others;

the quality and breadth of our technology;

our employees’ skills and our ability to recruit and retain skilled employees;

our cash flows under existing and potential future arrangements with licensees, partners and other parties; and

the availability of substantial capital resources to fund development and commercialization activities.

Our competitors may develop drug candidates and market drugs that are less expensive and more effective than our future drugs 
or that may render our drugs obsolete. Our current or future competitors may also commercialize competing drugs before we or our 
partners  can  launch  any  drugs  developed  from  our  drug  candidates.  These  organizations  also  compete  with  us  to  attract  qualified 
personnel and potential parties for acquisitions, joint ventures or other strategic alliances.

If omecamtiv mecarbil is approved for marketing by the FDA or other regulatory authorities for the treatment of heart failure 
with  reduced  ejection  fraction,  it  would  compete  against  other  drugs  used  for  the  treatment  of  chronic  heart  failure.  These  include 
generic drugs, such as milrinone, dobutamine or digoxin and branded drugs such as Corlanor (ivabradine), and Entresto®. Omecamtiv 
mecarbil  could  also  potentially  compete  against  other  novel  drug  candidates  and  therapies  in  development,  such  as  those  being 
developed  by  ARCA  biopharma,  Inc.,  Novartis,  Bayer,  Merck,  Theravance  Biopharma,  Capricor,  Cardiorentis  AG,  Ono 
Pharmaceutical Company, ARMGO Pharma, Inc., Bristol-Myers Squibb Company, Zensun Sci & Tech, Ltd., and Tenax Therapeutics 
(formerly  known  as  Oxygen  Biotherapeutics,  Inc.).  In  addition,  there  are  a  number  of  medical  devices  both  marketed  and  in 
development for the potential treatment of heart failure.

If reldesemtiv is approved by the FDA or other regulatory authorities for the treatment of ALS, it may then compete with other 
drugs  used  for  the  treatment  of  ALS  including  Radicava  (edaravone)  and  potential  new  therapies  for  ALS  that  are  currently  being 
developed  by  companies  such  as  Ionis  Pharmaceuticals,  Inc.  (in  collaboration  with  Biogen),  Genervon  Biopharmaceuticals,  LLC, 
Orion  Pharmaceuticals,  Orphazyme,  Eisai  Co.,  Ltd.,  Genentech,  Inc.,  BioElectron  Technology  Corporation,  Q  Therapeutics,  AB 
Science,  VM  Biopharma,  Mallinckrodt  Pharmaceuticals,  Chronos  Therapeutics,  Denali  Therapeutics  (in  collaboration  with  Sanofi), 
and  MediciNova,  Inc.  In  addition,  BrainStorm  Cell  Therapeutics  and  Neuralstem,  Inc.  are  each  conducting  clinical  development  of 
stem cell therapies for the potential treatment of ALS. If reldesemtiv is approved by the FDA or other regulatory authorities for the 
potential treatment of SMA, potential competitors include Roche (in collaboration with PTC Therapeutics), AveXis, Inc. (a Novartis 
company), Biogen Inc. (in collaboration with Ionis Pharmaceuticals, Inc.), Novartis AG, and Bioblast Pharma Ltd. Drugs that could 
compete  with  reldesemtiv  could  also  compete  against  tirasemtiv  in  ALS  or  other  neuromuscular  diseases,  should  the  appropriate 
clinical  trials  be  conducted.  If  reldesemtiv  is  approved  by  the  FDA  for  the  potential  treatment  of  non-neuromuscular  indications 
associated with muscle weakness, potential competitors include Ligand Pharmaceuticals, Inc., GTx, Inc., Regeneron Pharmaceuticals, 
Inc.  (in  collaboration  with  Sanofi),  Eli  Lilly &  Company,  Acceleron  Pharma,  Stealth  BioTherapeutics,  Scholar  Rock,  Summit 
Therapeutics, Pfizer Inc., and Novartis (in collaboration with MorphoSys AG).

Employees

As of December 31, 2018, we had 130 full-time employees.

We  have  no  collective  bargaining  agreements  with  our  employees,  and  we  have  not  experienced  any  work  stoppages.  We 

believe that our relations with our employees are good.

Item 1A.

Risk Factors

In evaluating our business, you should carefully consider the following risks in addition to the other information in this report. 
Any  of  the  following  risks  could  materially  and  adversely  affect  our  business,  results  of  operations,  financial  condition  or  your 
investment  in  our  securities,  and  many  are  beyond  our  control.  The  risks  and  uncertainties  described  below  are  not  the  only  ones 
facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also adversely 
affect our business.

Risks Related To Our Business

We have a history of significant losses and may not achieve or sustain profitability and, as a result, you may lose all or part of 
your investment.

We have generally incurred operating losses in each year since our inception in 1997, due to costs incurred in connection with 
our research and development activities and general and administrative costs associated with our operations. Our drug candidates are 
all in early through late-stage clinical testing, and we and our partners must conduct significant additional clinical trials before we and 
our partners can seek the regulatory approvals necessary to begin commercial sales of our drugs. We expect to incur increasing losses 
for at least several more years, as we continue our research activities and conduct development of, and seek regulatory approvals for, 
our drug candidates, and commercialize any approved drugs. If our drug candidates fail or do not gain regulatory approval, or if our 
drugs do not achieve market acceptance, we will not be profitable. If we fail to become and remain profitable, or if we are unable to 
fund our continuing losses, you could lose all or part of your investment.

We will need substantial additional capital in the future to sufficiently fund our operations.

We  have  consumed  substantial  amounts  of  capital  to  date,  and  our  operating  expenditures  will  increase  over  the  next  several 
years if we expand our research and development activities. We have funded our operations and capital expenditures with proceeds 
primarily from private and public sales of our equity securities, a royalty monetization agreement, strategic alliances, long-term debt, 
other financings, interest on investments and grants. We believe that our existing cash and cash equivalents, short-term investments 
and interest earned on investments should be sufficient to meet our projected operating requirements for at least the next 12 months. 
We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner 
than we currently expect. Because of the numerous risks and uncertainties associated with the development of our drug candidates and 
other research and development activities, including risks and uncertainties that could impact the rate of progress of our development 
activities,  we  are  unable  to  estimate  with  certainty  the  amounts  of  capital  outlays  and  operating  expenditures  associated  with these 
activities.

For  the  foreseeable  future,  our  operations  will  require  significant  additional  funding,  in  large  part  due  to  our  research  and 
development  expenses  and  the  absence  of  any  revenues  from  product  sales.  For  example,  we  will  require  significant  additional 
funding to enable us to conduct further development of our product candidates. Until we can generate a sufficient amount of product 
revenue, we expect to raise future capital through strategic alliance and licensing arrangements, public or private equity offerings and 
debt  financings.  We  do  not  currently  have  any  commitments  for  future  funding  other  than  reimbursements,  milestone  and  royalty 
payments that we may receive under our collaboration agreements with Amgen and Astellas. We may not receive any further funds 
under those agreements. Our ability to raise funds may be adversely impacted by current economic conditions. As a result of these and 
other factors, we do not know whether additional financing will be available when needed, or that, if available, such financing would 
be on terms favorable to our stockholders or us.

To the extent that we raise additional funds through strategic alliances or licensing or other arrangements with third parties, we 
will likely have to relinquish valuable rights to our technologies, research programs or drug candidates, or grant licenses on terms that 
may not be favorable to us. To the extent that we raise additional funds by issuing equity securities, our stockholders will experience 
additional dilution and our share price may decline. To the extent that we raise additional funds through debt financing, the financing 
may  involve  covenants  that  restrict  our  business  activities.  In  addition,  funding  from  any  of  these  sources,  if  needed,  may  not  be 
available to us on favorable terms, or at all, or in accordance with our planned timelines.

If  we  cannot  raise  the  funds  we  need  to  operate  our  business,  we  will  need  to  delay  or  discontinue  certain  research  and 

development activities, and our stock price may be negatively affected.

We are obligated to develop and maintain proper and effective internal control over financial reporting. In February 2019, our 
management identified a material weakness in our internal control over financial reporting. If we are unable to remediate the 
material  weakness  or  other  control  deficiencies  are  identified,  we  may  not  be  able  to  report  our  financial  results  accurately, 

16

prevent fraud or file our periodic reports in a timely manner, which may adversely affect investor confidence in our company 
and, as a result, the value of our common stock.

We are required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, 

the effectiveness of our internal control over financial reporting.

Complying with Section 404 requires a rigorous compliance program as well as adequate time and resources. We may not be 
able to complete our internal control evaluation, testing and any required remediation in a timely fashion. Additionally, if we identify 
one or more material weaknesses in our internal control over financial reporting, we will not be able to assert that our internal controls 
are effective. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that 
there  is  a  reasonable  possibility  that  a  material  misstatement  of  the  company’s  annual  or  interim  financial  statements  will  not  be 
prevented or detected on a timely basis. On February 27, 2019, our management concluded that our internal controls over financial 
reporting were ineffective as of December 31, 2018 due to the identification of a material weakness. As of December 31, 2018, we 
identified a material weakness related to the ineffective review and verification of internally prepared reports and analyses utilized in 
our  financial  statement  closing  process.  The  material  weakness  is  related  to  employee  turnover  resulting  in  a  temporary  lack  of 
resources  in  financial  reporting  roles  with  the  appropriate  skills  to  perform  effective  review  during  our  financial  statement  close 
process. This material weakness did not result in the restatement of prior quarterly or annually filed financial statements. To remediate 
the material weakness described above, we are actively recruiting for open positions within the accounting department and will, as 
necessary,  supplement  any  interim  staffing  needs  with  temporary  resources.  We  will  also  continue  to  evaluate  and  improve  our 
internal controls, processes and procedures in the financial statement close process.

We also previously concluded that our internal controls over financial reporting were not effective as of September 30, 2016, 
because  a  material  weakness  existed  in  our  internal  control  over  financial  reporting  related  to  research  and  development  expenses 
associated  with  the  review  of  clinical  trial  expenses  incurred  under  our  clinical  research  organization  trial  agreements,  including  in 
part, our review of information received from third-party service providers that is used in the operation of this control. We remediated 
this material weakness as of December 31, 2016.

We cannot be certain that these measures will successfully remediate the material weakness identified in connection with the 
audit of our financial statements for the year ended December 31, 2018 and that other material weaknesses and control deficiencies 
will not be discovered in the future. If our efforts are not successful or other material weaknesses are identified in the future or we are 
not  able  to  comply  with  the  requirements  of  Section 404  in  a  timely  manner,  our  reported  financial  results  could  be  materially 
misstated,  we  would  receive  an  adverse  opinion  regarding  our  internal  controls  over  financial  reporting  from  our  independent 
registered  public  accounting  firm,  and  we  could  be  subject  to  investigations  or  sanctions  by  regulatory  authorities,  which  would 
require  additional  financial  and  management  resources,  and  the  value  of  our  common  stock  could  decline.  In  addition,  because  we 
concluded  that  our  internal  controls  over  financial  reporting  were  not  effective  as  of  December  31,  2018  and  as  of  September 30, 
2016,  and  to  the  extent  we  identify  future  weaknesses  or  deficiencies,  there  could  be  material  misstatements  in  our  consolidated 
financial  statements  and  we  could  fail  to  meet  our  financial  reporting  obligations.  As  a  result,  our  ability  to  obtain  additional 
financing,  or  obtain  additional  financing  on  favorable  terms,  could  be  materially  and  adversely  affected  which,  in  turn,  could 
materially and adversely affect our business, our financial condition and the value of our common stock. If we are unable to assert that 
our internal control over financial reporting is effective in the future, or if our independent registered public accounting firm is unable 
to express an opinion or expresses an adverse opinion on the effectiveness of our internal controls in the future, investor confidence in 
the accuracy and completeness of our financial reports could be further eroded, which would have a material adverse effect on the 
price of our common stock.

Covenants in our Loan Agreement restrict our business and operations in many ways and if we do not effectively manage our 
covenants,  our  financial  conditions  and  results  of  operations  could  be  adversely  affected.  Our  operations  may  not  provide 
sufficient cash to meet the repayment obligations of our debt incurred under the Loan Agreement.

The Loan Agreement requires that we comply with certain covenants applicable to us, including among other things, covenants 
restricting  dispositions,  changes  in  business,  management,  ownership  or  business  locations,  mergers  or  acquisitions,  indebtedness, 
encumbrances, distributions, investments, transactions with affiliates and subordinated debt, any of which could restrict our business 
and operations, particularly our ability to respond to changes in our business or to take specified actions to take advantage of certain 
business opportunities that may be presented to us. Our failure to comply with any of the covenants could result in a default under the 
Loan  Agreement,  which  could  permit  the  lenders  to  declare  all  or  part  of  any  outstanding  borrowings  to  be  immediately  due  and 
payable. 

17

If we are unable to repay those amounts, the Lenders could proceed against the collateral granted to them to secure that debt, 
which would seriously harm our business. In addition, should we be unable to comply with these covenants or if we default on any 
portion of our outstanding borrowings, the lenders can also impose a 5.0% penalty. 

We have never generated, and may never generate, revenues from commercial sales of our drugs and we will not have drugs to 
market for at least several years, if ever.

We currently have no drugs for sale and we cannot guarantee that we will ever develop or obtain approval to market any drugs. 
To  receive  marketing  approval  for  any  drug  candidate,  we  must  demonstrate  that  the  drug  candidate  satisfies  rigorous  standards of 
safety and efficacy to the FDA in the United States and other regulatory authorities abroad. We and our partners will need to conduct 
significant additional research and preclinical and clinical testing before we or our partners can file applications with the FDA or other 
regulatory authorities for approval of any of our drug candidates. In addition, to compete effectively, our drugs must be easy to use, 
cost-effective, covered by insurance or government sponsored medical plans, and economical to manufacture on a commercial scale, 
compared to other therapies available for the treatment of the same conditions. We may not achieve any of these objectives. Currently, 
our drug candidates in clinical development include omecamtiv mecarbil for the potential treatment of heart failure and reldesemtiv 
for  the  potential  treatment  of  SMA,  ALS  and  potentially  other  neuromuscular  and  non-neuromuscular  indications  associated  with 
muscle weakness. We cannot be certain that the clinical development of our current or any future drug candidates will be successful, 
that they will receive the regulatory approvals required to commercialize them, that they will ultimately be accepted by prescribers or 
reimbursed  by  insurers  or  that  any  of  our  other  research  programs  will  yield  a  drug  candidate  suitable  for  clinical  testing  or 
commercialization. Our commercial revenues, if any, will be derived from sales of drugs that we do not expect to be commercially 
marketed for at least several years, if at all. The development of any one or all of these drug candidates may be discontinued at any 
stage of our clinical trials programs and we may not generate revenue from any of these drug candidates.

Clinical  trials  may  fail  to  demonstrate  the  desired  safety  and  efficacy  of  our  drug  candidates,  which  could  prevent  or 
significantly delay completion of clinical development and regulatory approval.

Prior to receiving approval to commercialize any of our drug candidates, we or our partners must adequately demonstrate to the 
satisfaction  of  FDA  and  foreign  regulatory  authorities  that  the  drug  candidate  is  sufficiently  safe  and  effective  with  substantial 
evidence from well-controlled clinical trials. We or our partners will need to demonstrate efficacy in clinical trials for the treatment of 
specific  indications  and  monitor  safety  throughout  the  clinical  development  process  and  following  approval.  None  of  our  drug 
candidates have yet met the safety and efficacy standards required for regulatory approval for commercialization and they may never 
do  so.  In  addition,  for  each  of  our  preclinical  compounds,  we  or  our  partners  must  adequately  demonstrate  satisfactory  chemistry, 
formulation, quality, stability and toxicity in order to submit an IND to the FDA, or an equivalent application in foreign jurisdictions, 
that would allow us to advance that compound into clinical trials. Furthermore, we or our partners may need to submit separate INDs 
(or  foreign  equivalent)  to  different  divisions  within  the  FDA  (or  foreign  regulatory  authorities)  in  order  to  pursue  clinical  trials  in 
different therapeutic areas. Each new IND (or foreign equivalent) must be reviewed by the new regulatory division before the clinical 
trial under its jurisdiction can proceed, entailing all the risks of delay inherent to regulatory review. If our or our partners’ current or 
future  preclinical  studies  or  clinical  trials  are  unsuccessful,  our  business  will  be  significantly  harmed  and  our  stock  price  could  be 
negatively affected.

All of our drug candidates are prone to the risks of failure inherent in drug development. Preclinical studies may not yield results 
that would adequately support the filing of an IND (or a foreign equivalent) with respect to our potential drug candidates. Even if the 
results  of  preclinical  studies  for  a  drug  candidate  are  sufficient  to  support  such  a  filing,  the  results  of  preclinical  studies  do  not 
necessarily predict the results of clinical trials. As an example, because the physiology of animal species used in preclinical studies 
may vary substantially from other animal species and from humans, it may be difficult to assess with certainty whether a finding from 
a  study  in  a  particular  animal  species  will  result  in  similar  findings  in  other  animal  species  or  in  humans.  For  any  of  our  drug 
candidates, the results from Phase 1 clinical trials in healthy volunteers and clinical results from Phase 1 and 2 trials in patients are not 
necessarily indicative of the results of later and larger clinical trials that are necessary to establish whether the drug candidate is safe 
and effective for the applicable indication. Likewise, interim results from a clinical trial may not be indicative of the final results from 
that trial, and results from early Phase 2 clinical trials may not be indicative of the results from later clinical trials. For example, early 
Phase 2 clinical trials of tirasemtiv in patients with ALS showed encouraging dose-related trends in measurements of the ALSFRS-R, 
a  clinically  validated  instrument  designed  to  measure  disease  progression  and  changes  in  functional  status,  for  patients  receiving 
tirasemtiv compared to those receiving placebo. However, BENEFIT-ALS, a Phase 2b clinical trial of tirasemtiv in patients with ALS, 
did  not  achieve  its  primary  efficacy  endpoint,  the  mean  change  from  baseline  in  the  ALSFRS-R  for  patients  receiving  tirasemtiv 
compared  to  those  receiving  placebo,  and  in  November  2017,  we  announced  that  VITALITY-ALS  did  not  achieve  its  primary 
endpoint or secondary endpoints. Following the results of VITALITY-ALS, we suspended development of tirasemtiv.

Moreover, the Phase 2 clinical trial of reldesemtiv in COPD and Phase 1b clinical trial of reldesemtiv in elderly subjects with 
limited mobility did not show efficacy, and there can be no assurance that reldesemtiv will demonstrate efficacy in other indications, 
regardless of the phase of development. 

In  addition,  while  the  clinical  trials  of  our  drug  candidates  are  designed  based  on  the  available  relevant  information,  such 
information may not accurately predict what actually occurs during the course of the trial itself, which may have consequences for the 
conduct of an ongoing clinical trial or for the eventual results of that trial. For example, the number of patients planned to be enrolled 
in a placebo-controlled clinical trial is determined in part by estimates relating to expected treatment effect and variability about the 

18

primary endpoint. These estimates are based upon earlier non-clinical and clinical studies of the drug candidate itself and clinical trials 
of  other  drugs  thought  to  have  similar  effects  in  a  similar  patient  population.  If  information  gained  during  the  conduct  of  the  trial 
shows these estimates to be inaccurate, we may elect to adjust the enrollment accordingly, which may cause delays in completing the 
trial, additional expense or a statistical penalty to apply to the evaluation of the trial results.

Furthermore, in view of the uncertainties inherent in drug development, such clinical trials may not be designed with focus on 
indications,  patient  populations,  dosing  regimens,  endpoints,  safety,  efficacy  or  pharmacokinetic  parameters  or  other  variables  that 
will provide the necessary safety or efficacy data to support regulatory approval to commercialize the resulting drugs. For example, 
we believe that effects on respiratory function, including SVC, may be appropriate as a clinical endpoint for reldesemtiv; however, 
regulatory  authorities  may  not  accept  these  effects  as  a  clinical  endpoint  to  support  registration  of  reldesemtiv  for  the  treatment  of 
ALS. Clinical trials of our drug candidates are designed based on guidance or advice from regulatory agencies, which is subject to 
change during the development of the drug candidate at any time. Such a change in a regulatory agency’s guidance or advice may 
cause that agency to deem results from trials to be insufficient to support approval of the drug candidate and require further clinical 
trials of that drug candidate to be conducted. In addition, individual patient responses to the dose administered of a drug may vary in a 
manner that is difficult to predict. Also, the methods we select to assess particular safety, efficacy or pharmacokinetic parameters may 
not yield the same statistical precision in estimating our drug candidates’ effects as may other methodologies. Even if we believe the 
data collected from clinical trials of our drug candidates are promising, these data may not be sufficient to support approval by the 
FDA or foreign regulatory authorities. Non-clinical and clinical data can be interpreted in different ways. Accordingly, the FDA or 
foreign regulatory authorities could interpret these data in different ways from us or our partners, which could delay, limit or prevent 
regulatory approval.

Furthermore,  while  planned  interim  analyses  in  clinical  trials  can  enable  early  terminations  for  futility  or  for  overwhelming 
efficacy,  the  timing,  which  can  be  based  on  accrual  of  events,  enrollment  or  other  factors,  and  the  results  of  such  analyses,  is 
unpredictable. For example, in GALACTIC-HF, a Phase 3 clinical trial of omecamtiv mecarbil, we anticipate an interim analysis for 
futility in the first half of 2019 and another interim analysis for overwhelming efficacy in 2020, but the exact timing and outcome of 
such interim analyses are uncertain. Although our GALACTIC-HF trial is being conducted under an SPA agreement with FDA, there 
is no guarantee that either the trial will be successful, or even if successful, that FDA would approve any resulting NDA.

Administering  any  of  our  drug  candidates  or  potential  drug  candidates  may  produce  undesirable  side  effects,  also  known  as 
adverse  events.  Toxicities  and  adverse  events  observed  in  preclinical  studies  for  some  compounds  in  a  particular  research  and 
development  program  may  also  occur  in  preclinical  studies  or  clinical  trials  of  other  compounds  from  the  same  program.  Potential 
toxicity  issues  may  arise  from  the  effects  of  the  active  pharmaceutical  ingredient  itself  or  from  impurities  or  degradants  that  are 
present in the active pharmaceutical ingredient or could form over time in the formulated drug candidate or the active pharmaceutical 
ingredient. These toxicities or adverse events could delay or prevent the filing of an IND (or a foreign equivalent) with respect to our 
drug candidates or potential drug candidates or cause us, our partners or the FDA or foreign regulatory authorities to modify, suspend 
or terminate clinical trials with respect to any drug candidate at any time during the development program. Further, the administration 
of two or more drugs contemporaneously can lead to interactions between them, and our drug candidates may interact with other drugs 
that trial subjects are taking. If the adverse events are severe or frequent enough to outweigh the potential efficacy of a drug candidate, 
the FDA or other regulatory authorities could deny approval of that drug candidate for any or all targeted indications. Even if one or 
more of our drug candidates were approved for sale as drugs, the occurrence of even a limited number of adverse events or toxicities 
when  used  in  large  populations  may  cause  the  FDA  or  foreign  regulatory  authorities  to  impose  restrictions  on,  or  stop,  the  further 
marketing  of  those  drugs.  Indications  of  potential  adverse  events  or  toxicities  which  do  not  seem  significant  during  the  course  of 
clinical trials may later turn out to actually constitute serious adverse events or toxicities when a drug is used in large populations or 
for extended periods of time.

We have observed certain adverse events in the clinical trials conducted with our drug candidates. For example, in clinical trials 
of omecamtiv mecarbil, adverse events of chest discomfort, palpitations, dizziness and feeling hot, increases in heart rate, declines in 
blood  pressure,  electrocardiographic  changes  consistent  with  acute  myocardial  ischemia  and  transient  rises  in  the  MB  fraction  of 
creatine  kinase  and  cardiac  troponins  I  and  T,  which  are  indicative  of  myocardial  infarction  were  observed  during  treatment  with 
omecamtiv mecarbil.

19

In  addition,  clinical  trials  of  reldesemtiv  and  omecamtiv  mecarbil  enroll  patients  who  typically  suffer  from  serious  diseases 
which put them at increased risk of death. These patients may die while receiving our drug candidates. In such circumstances, it may 
not be possible to exclude with certainty a causal relationship to our drug candidate, even though the responsible clinical investigator 
may view such an event as not study drug-related.

Any failure or significant delay in completing preclinical studies or clinical trials for our drug candidates, or in receiving and 
maintaining  regulatory  approval  for  the  sale  of  any  resulting  drugs,  may  significantly  harm  our  business  and  negatively  affect  our 
stock price.

The  failure  of  a  number  of  Phase  3  clinical  trials  evaluating  other  compounds  as  potential  treatments  for  patients  with  ALS 
may suggest an increased risk that our clinical development program of reldesemtiv in patients with ALS will also fail.

In  recent  years,  a  number  of  Phase  3  clinical  trials  of  potential  treatments  for  ALS  have  failed  to  demonstrate  the  requisite 
efficacy for regulatory approval or for their continued development. These include our trial of tirasemtiv known as VITALITY-ALS, 
Biogen’s  trial  of  dexpramipexole,  known  as  EMPOWER,  the  National  Institute  of  Neurological  Disorders  and  Stroke’s  trial  of 
ceftriaxone, and Trophos SA’s trial of olesoxime. Reldesemtiv, like these compounds, may fail in clinical development if it does not 
show a statistically significant level of clinical efficacy or if the adverse event profile is too great compared to it benefits. Further, 
even if we believe the data collected from the planned clinical development program of reldesemtiv are promising and should support 
approval, the FDA or other regulatory authorities may not deem these data to be sufficient to support approval.

Clinical trials are expensive, time-consuming and subject to delay.

Clinical  trials  are  subject  to  rigorous  regulatory  requirements  and  are  very  expensive,  difficult  and  time-consuming  to  design 
and implement. The length of time and number of trial sites and patients required for clinical trials vary substantially based on the 
type, complexity, novelty, intended use of the drug candidate and safety concerns. Clinical trials of our current drug candidates can 
each continue for several more years. However, the clinical trials for all or any of our drug candidates may take significantly longer to 
complete. The commencement and completion of our or our partners’ clinical trials could be delayed or prevented by many factors, 
including, but not limited to:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

delays  in  obtaining,  or  inability  to  obtain,  regulatory  or  other  approvals  to  commence  and  conduct  clinical  trials  in  the 
manner  we  or  our  partners  deem  necessary  for  the  appropriate  and  timely  development  of  our  drug  candidates  and 
commercialization of any resulting drugs;

delays  in  identifying  and  reaching  agreement,  or  inability  to  identify  and  reach  agreement,  on  acceptable  terms,  with 
prospective clinical trial sites and other entities involved in the conduct of our or our partners’ clinical trials;

delays  or  additional  costs  in  developing,  or  inability  to  develop,  appropriate  formulations  of  our  drug  candidates  for 
clinical trial use;

slower than expected rates of patient recruitment and enrollment;

for those drug candidates that are the subject of a strategic alliance, delays in reaching agreement with our partner as to 
appropriate development strategies;

a regulatory authority may require changes to a protocol for a clinical trial that then may require approval from regulatory 
agencies in other jurisdictions where the trial is being conducted;

an  institutional  review  board  (“IRB”)  or  its  foreign  equivalent  may  require  changes  to  a  protocol  that  then  require 
approval  from  regulatory  agencies  and  other  IRBs  and  their  foreign  equivalents,  or  regulatory  authorities  may  require 
changes to a protocol that then require approval from the IRBs or their foreign equivalents;

for  clinical  trials  conducted  in  foreign  countries,  the  time  and  resources  required  to  identify,  interpret  and  comply  with 
foreign regulatory requirements or changes in those requirements, and political instability or natural disasters occurring in 
those countries;

lack of effectiveness of our drug candidates during clinical trials;

unforeseen safety issues;

inadequate supply, or delays in the manufacture or supply, of clinical trial materials;

uncertain dosing issues;

failure by us, our partners, or clinical research organizations, investigators or site personnel engaged by us or our partners 
to  comply  with  good  clinical  practices  and  other  applicable  laws  and  regulations,  including  those  concerning  informed 
consent;

inability or unwillingness of investigators or their staffs to follow clinical protocols;

failure by our clinical research organizations, clinical manufacturing organizations and other third parties supporting our 
or our partners’ clinical trials to fulfill their obligations;

inability to monitor patients adequately during or after treatment;

20

•

•

introduction of new therapies or changes in standards of practice or regulatory guidance that render our drug candidates or 
their clinical trial endpoints obsolete; and

results from non-clinical studies that may adversely impact the timing or further development of our drug candidates.

We do not know whether planned clinical trials will begin on time, or whether planned or currently ongoing clinical trials will 
need  to  be  restructured  or  will  be  completed  on  schedule,  if  at  all.  Significant  delays  in  clinical  trials  will  impede  our  ability  to 
commercialize our drug candidates and generate revenue and could significantly increase our development costs.

If  we  encounter  difficulties  enrolling  patients  in  our  clinical  trials,  our  clinical  development  activities  could  be  delayed  or 
otherwise adversely affected.

The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a 
sufficient  number  of  patients  who  remain  in  the  trial  until  its  conclusion.  We  may  experience  difficulties  in  patient  enrollment  in 
clinical trials for a variety of reasons. The enrollment of patients depends on many factors, including:

•
•
•
•
•
•

•
•

the patient eligibility criteria defined in the protocol;
the size of the patient population required for analysis of the trial’s primary endpoints;
the proximity of patients to study sites;
the design of the trial;
the ability to recruit clinical trial investigators with the appropriate competencies and experience;
clinicians’  and  patients’  perceptions  as  to  the  potential  advantages  of  the  product  candidate  being  studied  in  relation  to 
other  available  therapies  or  clinical  trials,  including  any  new  drugs  that  may  be  approved  for  the  indications  we  are 
investigating or clinical trial results;
the ability to obtain and maintain patient consents; and
the risk that patients enrolled in clinical trials will drop out of the trials before completion.

In addition, our and our partners’ clinical trials will compete with other clinical trials for product candidates that are in the same 
therapeutic  areas  as  our  and  our  partners’  product  candidates,  and  this  competition  will  reduce  the  number  and  types  of  patients 
available to us, because some patients who might have opted to enroll in our or our partners’ trials may instead opt to enroll in a trial 
being conducted by one of our competitors. Since the number of qualified clinical investigators is limited, we expect to conduct some 
of our or our partners’ clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number of 
patients who are available for our clinical trials in such clinical trial site. 

Delays  in  patient  enrollment  may  result  in  increased  costs  or  may  affect  the  timing  or  outcome  of  the  planned  clinical  trials, 
which  could  prevent  completion  of  these  trials  and  adversely  affect  our  and  our  partners’  ability  to  advance  the  development  of 
product candidates.

We depend on Amgen for the conduct and funding of the development and commercialization of omecamtiv mecarbil.

Under  our  strategic  alliance,  Amgen  holds  an  exclusive  worldwide  license  to  our  drug  candidate  omecamtiv  mecarbil.  As  a 
result, Amgen is responsible for the development and obtaining and maintaining regulatory approval of omecamtiv mecarbil for the 
potential treatment of heart failure worldwide.

Amgen  is  conducting  GALACTIC-HF,  a  Phase  3  clinical  trial  of  omecamtiv  mecarbil.  We  do  not  control  the  development 
activities  being  conducted  or  that  may  be  conducted  in  the  future  by  Amgen,  including,  but  not  limited  to,  the  timing  of  initiation, 
termination  or  completion  of  clinical  trials,  the  analysis  of  data  arising  out  of  those  clinical  trials  or  the  timing  of  release  of  data 
concerning those clinical trials, which may impact our ability to report on Amgen’s results. Amgen may conduct these activities more 
slowly or in a different manner than we would if we controlled the development of omecamtiv mecarbil. Amgen is responsible for 
submitting future applications to the FDA and other regulatory authorities for approval of omecamtiv mecarbil and will be the owner 
of  marketing  approvals  issued  by  the  FDA  and  other  regulatory  authorities  for  omecamtiv  mecarbil,  subject  to  Servier’s  exclusive 
rights  for  the  commercialization  of  omecamtiv  mecarbil  in  Europe,  as  well  as  the  CIS,  including  Russia.  If  the  FDA  or  other 
regulatory authorities approve omecamtiv mecarbil, Amgen will also be responsible for the marketing and sale of the resulting drug, 
subject  to  our  right  to  co-promote  omecamtiv  mecarbil  in  North  America  in  connection  with  the  exercise  of  our  option  to  co-fund 
Phase  3  development  costs  of  omecamtiv  mecarbil  under  the  collaboration  and  subject  to  Servier’s  exclusive  rights  for  the 
commercialization  of  omecamtiv  mecarbil  in  Europe,  as  well  as  the  CIS,  including  Russia.  However,  we  cannot  control  whether 
Amgen  will  devote  sufficient  attention  and  resources  to  the  development  of  omecamtiv  mecarbil  or  will  proceed  in  an  expeditious 
manner, even with our exercise of our option and co-funding of the Phase 3 development program of omecamtiv mecarbil. Even if the 
FDA  or  other  regulatory  agencies  approve  omecamtiv  mecarbil,  Amgen  or  Servier  may  elect  not  to  proceed  with  the 
commercialization of the resulting drug in one or more countries.

21

Disputes  may  arise  between  us  and  Amgen,  which  may  delay  or  cause  the  termination  of  any  clinical  trials  of  omecamtiv 
mecarbil, result in significant litigation or cause Amgen to act in a manner that is not in our best interest. The costs associated with the 
continuing  development  of  omecamtiv  mecarbil  may  cause  Amgen  to  reconsider  the  terms  of  its  investment  and  seek  to  amend  or 
terminate our collaboration agreement or to suspend the development of omecamtiv mecarbil. If development of omecamtiv mecarbil 
does not progress for these or any other reasons, we would not receive further milestone payments or royalties on product sales from 
Amgen with respect to omecamtiv mecarbil. If the results of one or more clinical trials with omecamtiv mecarbil do not meet Amgen’s 
expectations at any time, Amgen may elect to terminate further development of omecamtiv mecarbil or certain of the potential clinical 
trials  for  omecamtiv  mecarbil,  even  if  the  actual  number  of  patients  treated  at  that  time  is  relatively  small.  In  addition,  Amgen 
generally  has  discretion  to  elect  whether  to  pursue  or  abandon  the  development  of  omecamtiv  mecarbil  and  may  terminate  our 
strategic alliance for any reason upon six months prior notice. With our consent, Amgen granted Servier an option to commercialize 
omecamtiv mecarbil in Europe and the CIS, including Russia, which Servier decided to exercise. In August 2016, we entered into a 
letter agreement with Amgen and Servier, which provides that if Amgen’s rights to omecamtiv mecarbil are terminated with respect to 
the territory subject to Servier’s sublicense, the sublicensed rights previously granted by Amgen to Servier with respect to omecamtiv 
mecarbil will remain in effect and become a direct license or sublicense of such rights by us to Servier, on substantially the same terms 
as those in the Option, License and Collaboration Agreement between Amgen and Servier. If Amgen abandons omecamtiv mecarbil, it 
would result in a delay in or could prevent us from commercializing omecamtiv mecarbil and would delay and could prevent us from 
obtaining revenues for this drug candidate. In addition, we would be required to provide Servier with a direct license or sublicense and 
the rights to commercialize omecamtiv mecarbil in Europe and the CIS, including Russia, on terms that were not negotiated by us. 
There can be no assurance that we would be able to negotiate and enter into a definitive agreement with Servier on terms favorable or 
acceptable to us, or at all.

If  Amgen  abandons  development  of  omecamtiv  mecarbil  prior  to  regulatory  approval  or  if  it  elects  not  to  proceed  with 
commercialization  of  the  resulting  drug  following  regulatory  approval,  we  would  have  to  seek  a  new  partner  for  development  or 
commercialization, curtail or abandon that development or commercialization, or undertake and fund the development of omecamtiv 
mecarbil or commercialization of the resulting drug ourselves. If we seek a new partner but are unable to do so on acceptable terms, or 
at all, or do not have sufficient funds to conduct the development or commercialization of omecamtiv mecarbil ourselves, we would 
have to curtail or abandon that development or commercialization, which could harm our business.

We depend on Astellas for the conduct and funding of the development and commercialization of reldesemtiv.

The primary objective of our strategic alliance with Astellas is to advance skeletal muscle activators including reldesemtiv as 

novel therapies for indications associated with muscle weakness.

Astellas  has  an  exclusive  license  to  co-develop  and  commercialize  reldesemtiv  for  potential  application  in  certain 
neuromuscular  and  non-neuromuscular  indications  worldwide,  subject  to  certain  Cytokinetics’  development  and  commercialization 
rights. Under this strategic alliance, we have conducted a Phase 2 clinical trial of reldesemtiv in patients with SMA and Astellas has 
conducted a Phase 2 clinical trial of reldesemtiv in patients with COPD and a Phase 1b clinical trial of reldesemtiv in elderly subjects 
with limited mobility.

In  addition,  we  are  collaborating  with  Astellas  to  develop  reldesemtiv  in  ALS.  Astellas  is  primarily  responsible  for  the 

development of reldesemtiv in ALS, and we are responsible for conducting FORTITUDE-ALS.

We  do  not  control  the  development  activities  that  may  be  conducted  by  Astellas,  including,  but  not  limited  to,  the  timing  of 
initiation, termination or completion of clinical trials, the analysis of data arising out of those clinical trials or the timing of release of 
data concerning those clinical trials, which may impact our ability to report on Astellas’ results. Astellas may conduct these activities 
more slowly or in a different manner than we would. In general, Astellas is responsible for submitting future applications to the FDA 
or other regulatory authorities for approval of reldesemtiv and will be the owner of any marketing approvals issued by the FDA or 
other  regulatory  authorities  for  reldesemtiv.  If  the  FDA  or  other  regulatory  authorities  approve  reldesemtiv,  Astellas  will  also  be 
responsible for the marketing and sale of the resulting drug, subject to our right to co-promote the drug in the United States, Canada 
and,  for  neuromuscular  indications,  Europe.  However,  we  cannot  control  whether  Astellas  will  devote  sufficient  attention  and 
resources to the development of reldesemtiv or will proceed in an expeditious manner. Even if the FDA or other regulatory agencies 
approve reldesemtiv, Astellas may elect not to proceed with the commercialization of the resulting drug in one or more countries.

If the results of one or more clinical trials with reldesemtiv, including the Phase 2 clinical trial of reldesemtiv in patients with 
SMA, do not meet Astellas’ expectations at any time, Astellas may elect to terminate further development of reldesemtiv or certain of 
the potential clinical trials for reldesemtiv, even if the actual number of patients treated at that time is relatively small. In addition, 
Astellas generally has discretion to elect whether to pursue or abandon the development of reldesemtiv. Astellas may terminate our 
strategic  alliance  in  whole  or  in  part  for  any  reason  upon  six  months  prior  notice  at  any  time  following  expiration  of  the  strategic 
alliance’s research term, which will expire December 31, 2019. If Astellas abandons reldesemtiv, it would result in a delay in or could 
prevent us from further developing or commercializing reldesemtiv and would delay and could prevent us from obtaining revenues for 
this drug candidate. Disputes may arise between us and Astellas, which may delay or cause the termination of any clinical trials of 
reldesemtiv,  result  in  significant  litigation  or  cause  Astellas  to  act  in  a  manner  that  is  not  in  our  best  interest.  If  development  of 
reldesemtiv does not progress for these or any other reasons, we would not receive further milestone payments or royalties on product 
sales from Astellas with respect to reldesemtiv. If Astellas abandons development of reldesemtiv prior to regulatory approval or if it 

22

elects not to proceed with commercialization of the resulting drug following regulatory approval, we would have to seek a new partner 
for  development  or  commercialization,  curtail  or  abandon  that  development  or  commercialization,  or  undertake  and  fund  the 
development of reldesemtiv or commercialization of the resulting drug ourselves. If we seek a new partner but are unable to do so on 
acceptable terms, or at all, or do not have sufficient funds to conduct the development or commercialization of reldesemtiv ourselves, 
we would have to curtail or abandon that development or commercialization, which could harm our business.

If we do not enter into strategic alliances for our unpartnered drug candidates or research and development programs or fail to 
successfully maintain our current or future strategic alliances, we may have to reduce, delay or discontinue our advancement of 
our drug candidates and programs or expand our research and development capabilities and increase our expenditures.

Drug  development  is  complicated  and  expensive.  We  currently  have  limited  financial  and  operational  resources  to  carry  out 
drug development. Our strategy for developing, manufacturing and commercializing our drug candidates currently requires us to enter 
into  and  successfully  maintain  strategic  alliances  with  pharmaceutical  companies  or  other  industry  participants  to  advance  our 
programs and reduce our expenditures on each program. Accordingly, the success of our development activities depends in large part 
on our current and future strategic partners’ performance, over which we have little or no control.

Our ability to commercialize drugs that we develop with our partners and that generate royalties from product sales depends on 
our partners’ abilities to assist us in establishing the safety and efficacy of our drug candidates, obtaining and maintaining regulatory 
approvals  and  achieving  market  acceptance  of  the  drugs  once  commercialized.  Our  partners  may  elect  to  delay  or  terminate 
development of one or more drug candidates, independently develop drugs that could compete with ours or fail to commit sufficient 
resources to the marketing and distribution of drugs developed through their strategic alliances with us. Our partners may not proceed 
with the development and commercialization of our drug candidates with the same degree of urgency as we would because of other 
priorities  they  face.  In  addition,  new  business  combinations  or  changes  in  a  partner’s  business  strategy  may  adversely  affect  its 
willingness or ability to carry out its obligations under a strategic alliance.

If  we  are  not  able  to  successfully  maintain  our  existing  strategic  alliances  or  establish  and  successfully  maintain  additional 
strategic alliances, we will have to limit the size or scope of, or delay or discontinue, one or more of our drug development programs 
or research programs, or undertake and fund these programs ourselves. Alternatively, if we elect to continue to conduct any of these 
drug development programs or research programs on our own, we will need to expand our capability to conduct clinical development 
by  bringing  additional  skills,  technical  expertise  and  resources  into  our  organization.  This  would  require  significant  additional 
funding, which may not be available to us on acceptable terms, or at all.

To the extent we elect to fund the development of a drug candidate, or the commercialization of a drug at our expense, we will 
need substantial additional funding.

The  discovery,  development  and  commercialization  of  new  drugs  is  costly.  As  a  result,  to  the  extent  we  elect  to  fund  the 

development of a drug candidate or the commercialization of a drug, we will need to raise additional capital to:

•

•

•

•

•

•

•

fund clinical trials and seek regulatory approvals;

expand our development capabilities;

engage third-party manufacturers for such drug candidate or drug;

build or access commercialization capabilities;

implement additional internal systems and infrastructure;

maintain, defend and expand the scope of our intellectual property; and

hire and support additional management and scientific personnel.

Our future funding requirements will depend on many factors, including, but not limited to:
•

the rate of progress and costs of our or our partners’ clinical trials and other research and development activities;

•

•

•

•

•

•

the costs and timing of seeking and obtaining regulatory approvals;

the costs associated with establishing manufacturing and commercialization capabilities;

the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

the costs of acquiring or investing in businesses, products and technologies;

the effect of competing technological and market developments; and

the status of, payment and other terms, and timing of any strategic alliance, licensing or other arrangements that we have 
entered into or may establish.

Until  we  can  generate  a  sufficient  amount  of  product  revenue  to  finance  our  cash  requirements,  which  we  may  never  do,  we 
expect to continue to finance our future cash needs primarily through strategic alliances and other financings. We cannot be certain 
that additional funding will be available on acceptable terms, or at all. If we are not able to secure additional funding when needed, we 
may have to delay, reduce the scope of or eliminate one or more of our clinical trials or research and development programs or future 

23

commercialization initiatives.

We  depend  on  contract  research  organizations  (“CROs”)  to  conduct  our  clinical  trials  and  have  limited  control  over  their 
performance. If these CROs do not successfully carry out their contractual duties or meet expected deadlines, or if we lose any 
of our CROs, we may not be able to obtain regulatory approval for or commercialize our product candidates on a timely basis, if 
at all.

We  have  used  and  intend  to  continue  to  use  a  limited  number  of  CROs  within  and  outside  of  the  United  States  to  conduct 
clinical trials of our drug candidates and related activities. We do not have control over many aspects of our CROs’ activities, and 
cannot  fully  control  the  amount,  timing  or  quality  of  resources  that  they  devote  to  our  programs.  CROs  may  not  assign  as  high  a 
priority to our programs or pursue them as diligently as we would if we were undertaking these programs ourselves. The activities 
conducted by our CROs therefore may not be completed on schedule or in a satisfactory manner. CROs may also give higher priority 
to relationships with our competitors and potential competitors than to their relationships with us. Outside of the United States, we are 
particularly dependent on our CROs’ expertise in communicating with clinical trial sites and regulatory authorities and ensuring that 
our clinical trials and related activities and regulatory filings comply with applicable laws.

Our CROs’ failure to carry out development activities on our behalf as agreed and in accordance with our and the FDA’s or 
other regulatory agencies’ requirements and applicable U.S. and foreign laws, or our failure to properly coordinate and manage these 
activities, could increase the cost of our operations and delay or prevent the development, approval and commercialization of our drug 
candidates. For example, in June 2013, we learned from our data management vendor for BENEFIT-ALS that a programming error in 
the  electronic  data  capture  system  controlling  study  drug  assignment  caused  58  patients  initially  randomized  to  and  treated  with 
tirasemtiv  to  receive  placebo  instead  at  a  certain  trial  visit  and  for  the  remainder  of  the  trial.  In  order  to  maintain  the  originally 
intended statistical power of the trial, we amended the protocol to permit enrollment of approximately 680 patients, or 180 patients in 
addition to the 500 patients allowed under the existing protocol. This protocol amendment resulted in additional costs and delays in 
conducting  BENEFIT-ALS.  Further,  for  the  quarter  ended  September 30,  2016,  we  determined  that  there  was  an  error  in  the 
accounting  for  the  recognition  of  clinical  research  and  development  expenses  related  to  the  information  received  from  one  of  our 
CROs, which resulted in a restatement of our clinical research and development expenses, related clinical accrual accounts and related 
financial disclosures as of and for the three and nine month periods ended September 30, 2016. In addition, if a CRO fails to perform 
as  agreed,  our  ability  to  collect  damages  may  be  contractually  limited.  If  we  fail  to  effectively  manage  the  CROs  carrying  out the 
development of our drug candidates or if our CROs fail to perform as agreed, the commercialization of our drug candidates will be 
delayed  or  prevented.  In  many  cases,  our  CROs  have  the  right  to  terminate  their  agreements  with  us  in  the  event  of  an  uncured 
material breach. Identifying, qualifying and managing performance of third-party service providers can be difficult, time consuming 
and cause delays in our development programs. In addition, there is a natural transition period when a new CRO commences work and 
the new CRO may not provide the same type or level of services as the original provider. If any of our relationships with our third-
party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so timely or on commercially 
reasonable terms.

We have no manufacturing capacity and depend on our strategic partners and contract manufacturers to produce our clinical 
trial  materials,  including  our  drug  candidates,  and  anticipate  continued  reliance  on  contract  manufacturers  for  the 
development and commercialization of our potential drugs.

We  do  not  currently  operate  manufacturing  facilities  for  clinical  or  commercial  production  of  our  drug  candidates.  We  have 
limited experience in drug formulation and manufacturing, and we lack the resources and the capabilities to manufacture any of our 
drug  candidates  on  a  clinical  or  commercial  scale.  Amgen  has  assumed  responsibility  to  conduct  these  activities  for  the  ongoing 
development  of  omecamtiv  mecarbil  worldwide.  Astellas  has  primary  responsibility  for  the  manufacturing  for  the  ongoing 
development of reldesemtiv worldwide. We expect to rely on contract manufacturers to supply all future drug candidates for which we 
conduct  development,  as  well  as  other  materials  required  to  conduct  our  clinical  trials.  If  any  of  our  existing  or  future  contract 
manufacturers  fail  to  perform  satisfactorily,  it  could  delay  development  or  regulatory  approval  of  our  drug  candidates  or 
commercialization of our drugs, producing additional losses and depriving us of potential product revenues. In addition, if a contract 
manufacturer fails to perform as agreed, our ability to collect damages may be contractually limited.

Our  drug  candidates  require  precise  high-quality  manufacturing.  The  failure  to  achieve  and  maintain  high  manufacturing 
standards, including failure to detect or control anticipated or unanticipated manufacturing errors or the frequent occurrence of such 
errors, could result in patient injury or death, discontinuance or delay of ongoing or planned clinical trials, delays or failures in product 
testing or delivery, cost overruns, product recalls or withdrawals and other problems that could seriously hurt our business. Contract 
drug  manufacturers  often  encounter  difficulties  involving  production  yields,  quality  control  and  quality  assurance  and  shortages  of 
qualified  personnel.  These  manufacturers  are  subject  to  stringent  regulatory  requirements,  including  the  FDA’s  current  good 
manufacturing  practices  regulations  and  similar  foreign  laws  and  standards.  Each  contract  manufacturer  must  pass  a  pre-approval 
inspection before we can obtain marketing approval for any of our drug candidates and following approval will be subject to ongoing 
periodic  unannounced  inspections  by  the  FDA,  the  U.S.  Drug  Enforcement  Agency  and  other  regulatory  agencies,  to  ensure  strict 
compliance with current good manufacturing practices and other applicable government regulations and corresponding foreign laws 
and  standards.  We  seek  to  ensure  that  our  contract  manufacturers  comply  fully  with  all  applicable  regulations,  laws  and  standards. 
However, we do not have control over our contract manufacturers’ compliance with these regulations, laws and standards. If one of 
our contract manufacturers fails to pass its pre-approval inspection or maintain ongoing compliance at any time, the production of our 

24

drug candidates could be interrupted, resulting in delays or discontinuance of our clinical trials, additional costs and potentially lost 
revenues.  In  addition,  failure  of  any  third-party  manufacturers  or  us  to  comply  with  applicable  regulations,  including  pre-  or  post-
approval inspections and the current good manufacturing practice requirements of the FDA or other comparable regulatory agencies, 
could result in sanctions being imposed on us. These sanctions could include fines, injunctions, civil penalties, failure of regulatory 
authorities  to  grant  marketing  approval  of  our  products,  delay,  suspension  or  withdrawal  of  approvals,  license  revocation,  product 
seizures  or  recalls,  operational  restrictions  and  criminal  prosecutions,  any  of  which  could  significantly  and  adversely  affect  our 
business.

In  addition,  our  existing  and  future  contract  manufacturers  may  not  perform  as  agreed  or  may  not  remain  in  the  contract 
manufacturing business for the time required to successfully produce, store and distribute our drug candidates. If a natural disaster, 
business  failure,  strike  or  other  difficulty  occurs,  we  may  be  unable  to  replace  these  contract  manufacturers  in  a  timely  or  cost-
effective manner and the production of our drug candidates would be interrupted, resulting in delays, loss of customers and additional 
costs.

Switching  manufacturers  or  manufacturing  sites  would  be  difficult  and  time-consuming  because  the  number  of  potential 
manufacturers is limited. In addition, before a drug from any replacement manufacturer or manufacturing site can be commercialized, 
the FDA and, in some cases, foreign regulatory agencies, must approve that site. These approvals would require regulatory testing and 
compliance  inspections.  A  new  manufacturer  or  manufacturing  site  also  would  have  to  be  educated  in,  or  develop  substantially 
equivalent processes for, production of our drugs and drug candidates. It may be difficult or impossible to transfer certain elements of 
a manufacturing process to a new manufacturer or for us to find a replacement manufacturer on acceptable terms quickly, or at all, 
either of which would delay or prevent our ability to develop drug candidates and commercialize any resulting drugs.

We may not be able to successfully manufacture our drug candidates in sufficient quality and quantity, which would delay or 
prevent us from developing our drug candidates and commercializing resulting approved drugs, if any.

To date, our drug candidates have been manufactured in quantities adequate for preclinical studies and early through late-stage 
clinical trials. In order to conduct large scale clinical trials for a drug candidate and for commercialization of the resulting drug if that 
drug candidate is approved for sale, we will need to manufacture some drug candidates in larger quantities. We may not be able to 
successfully repeat or increase the manufacturing capacity for any of our drug candidates, whether in collaboration with third-party 
manufacturers  or  on  our  own,  in  a  timely  or  cost-effective  manner  or  at  all.  If  a  contract  manufacturer  makes  improvements  in  the 
manufacturing  process  for  our  drug  candidates,  we  may  not  own,  or  may  have  to  share,  the  intellectual  property  rights  to  those 
improvements. Significant changes or scale-up of manufacturing may require additional validation studies, which are costly and which 
regulatory  authorities  must  review  and  approve.  In  addition,  quality  issues  may  arise  during  those  changes  or  scale-up  activities 
because of the inherent properties of a drug candidate itself or of a drug candidate in combination with other components added during 
the manufacturing and packaging process, or during shipping and storage of the finished product or active pharmaceutical ingredients. 
If we are unable to successfully manufacture of any of our drug candidates in sufficient quality and quantity, the development of that 
drug candidate and regulatory approval or commercial launch for any resulting drugs may be delayed or there may be a shortage in 
supply,  which  could  significantly  harm  our  business.  In  addition,  data  demonstrating  the  stability  of  both  drug  substance  and  drug 
product,  using  the  commercial  manufacturing  process  and  at  commercial  scale,  are  required  for  marketing  applications.  Failure  to 
produce  drug  substance  and  drug  products  in  a  timely  manner  and  obtain  stability  data  could  result  in  delay  of  submission  of 
marketing applications.

The mechanisms of action of our drug candidates are unproven, and we do not know whether we will be able to develop any 
drug of commercial value.

We have discovered and develop drug candidates that have what we believe are novel mechanisms of action directed against 
cytoskeletal targets. Because no currently-approved drugs appear to operate via the same biochemical mechanisms as our compounds, 
we cannot be certain that our drug candidates will result in commercially viable drugs that safely and effectively treat the indications 
for which we intend to develop them. The results we have seen for our compounds in preclinical models may not translate into similar 
results in humans, and results of early clinical trials in humans may not be predictive of the results of larger clinical trials that may 
later  be  conducted  with  our  drug  candidates.  Even  if  we  are  successful  in  developing  and  receiving  regulatory  approval  for  a  drug 
candidate for the treatment of a particular disease, we cannot be certain that it will be accepted by prescribers or be reimbursed by 
insurers or that we will also be able to develop and receive regulatory approval for that or other drug candidates for the treatment of 
other diseases. If we or our partners are unable to successfully develop and commercialize our drug candidates, our business will be 
materially harmed.

Our success depends substantially upon our ability to obtain and maintain intellectual property protection relating to our drug 
candidates, compounds and research technologies.

We own, co-own or hold exclusive licenses to a number of U.S. and foreign patents and patent applications directed to our drug 

candidates, compounds and research technologies. Our success depends on our ability to obtain patent protection both in the United 
States and in other countries for our drug candidates, their methods of manufacture and use, and our technologies. Our ability to 
protect our drug candidates, compounds and technologies from unauthorized or infringing use by third parties depends substantially on 
our ability to obtain and enforce our patents. If our issued patents and patent applications, if granted, do not adequately describe, 

25

enable or otherwise provide coverage of our technologies and drug candidates, we or our licensees would not be able to exclude others 
from developing or commercializing these drug candidates. Furthermore, the degree of future protection of our proprietary rights is 
uncertain because legal means may not adequately protect our rights or permit us to gain or keep our competitive advantage. If we are 
unable to obtain and maintain sufficient intellectual property protection for our technologies and drug candidates, or if the scope of the 
intellectual property protection obtained is not sufficiently broad, our competitors could develop and commercialize drug candidates 
similar or identical to ours, and our ability to successfully commercialize product candidates that we may pursue may be impaired. 

Obtaining and enforcing biopharmaceutical patents is costly, time consuming and complex, and we may not be able to file and 
prosecute all necessary or desirable patent applications, or maintain, enforce and license any patents that may issue from such patent 
applications,  at  a  reasonable  cost  or  in  a  timely  manner.  It  is  also  possible  that  we  will  fail  to  identify  patentable  aspects  of  our 
research and development output before it is too late to obtain patent protection. We may not have the right to control the preparation, 
filing and prosecution of patent applications, or to maintain the rights to patents licensed to third parties. Therefore, these patents and 
applications may not be prosecuted and enforced in a manner consistent with the best interests of our business.

Due  to  evolving  legal  standards  relating  to  the  patentability,  validity  and  enforceability  of  patents  covering  pharmaceutical 
inventions and the claim scope of these patents, our ability to enforce our existing patents and to obtain and enforce patents that may 
issue  from  any  pending  or  future  patent  applications  is  uncertain  and  involves  complex  legal,  scientific  and  factual  questions.  The 
standards  which  the  U.S.  Patent  and  Trademark  Office  and  its  foreign  counterparts  use  to  grant  patents  are  not  always  applied 
predictably or uniformly and are subject to change. To date, no consistent policy has emerged regarding the breadth of claims allowed 
in biotechnology and pharmaceutical patents. Thus, we cannot be sure that any patents will issue from any pending or future patent 
applications owned by, co-owned by or licensed to us. Even if patents do issue, we cannot be sure that the claims of these patents will 
be held valid or enforceable by a court of law, will provide us with any significant protection against competitive products, or will 
afford us a commercial advantage over competitive products. In particular:

•

•

•

•

•

•

•
•

we  or  our  licensors  might  not  have  been  the  first  to  make  the  inventions  covered  by  each  of  our  pending  patent 
applications or issued patents;
we  or  our  licensors  might  not  have  been  the  first  to  file  patent  applications  for  the  inventions  covered  by  our  pending 
patent applications or issued patents;
others  may  independently  develop  similar  or  alternative  technologies  or  duplicate  any  of  our  technologies  without 
infringing our intellectual property rights;
some or all of our or our licensors’ pending patent applications may not result in issued patents or the claims that issue 
may be narrow in scope and not provide us with competitive advantages;
our  and  our  licensors’  issued  patents  may  not  provide  a  basis  for  commercially  viable  drugs  or  therapies  or  may  be 
challenged and invalidated by third parties;
our  or  our  licensors’  patent  applications  or  patents  may  be  subject  to  interference,  post-grant  proceedings,  derivation, 
reexamination,  inter  partes  review,  opposition  or  similar  legal  and  administrative  proceedings  that  may  result  in  a 
reduction in their scope or their loss altogether;
we may not develop additional proprietary technologies or drug candidates that are patentable; or
the patents of others may prevent us or our partners from discovering, developing or commercializing our drug candidates.

We may not be able to protect our intellectual property rights throughout the world. Patent protection is afforded on a country-
by-country basis. Filing, prosecuting and defending patents on our product candidates in all countries throughout the world would be 
prohibitively  expensive,  and  our  intellectual  property  rights  in  some  countries  outside  the  United  States  can  be  less  extensive  than 
those in the United States. Many companies have encountered significant difficulties in protecting and defending intellectual property 
rights in foreign jurisdictions. Some of our development efforts are performed in countries outside of the United States through third-
party  contractors.  We  may  not  be  able  to  effectively  monitor  and  assess  intellectual  property  developed  by  these  contractors.  We 
therefore  may  not  be  able  to  effectively  protect  this  intellectual  property  and  could  lose  potentially  valuable  intellectual  property 
rights.  In  addition,  the  legal  protection  afforded  to  inventors  and  owners  of  intellectual  property  in  countries  outside  of  the  United 
States  may  not  be  as  protective  of  intellectual  property  rights  as  in  the  United  States.  Therefore,  we  may  be  unable  to  acquire  and 
protect intellectual property developed by these contractors to the same extent as if these development activities were being conducted 
in  the  United  States.  If  we  encounter  difficulties  in  protecting  our  intellectual  property  rights  in  foreign  jurisdictions,  our  business 
prospects could be substantially harmed.

Patent  terms  may  be  inadequate  to  protect  our  competitive  position  on  our  technologies  and  drug  candidates  for  an  adequate 
amount of time. Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a 
patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a 
patent, and the protection it affords, is limited. Even if patents covering our technologies and drug candidates are obtained, once the 
patent  life  has  expired,  we  may  be  open  to  competition  from  competitive  products,  including  generics  or  biosimilars.  Given  the 
amount of time required for the development, testing and regulatory review of new drug candidates, patents protecting such candidates 
might  expire  before  or  shortly  after  such  candidates  are  commercialized.  As  a  result,  our  owned,  co-owned  and  licensed  patent 

26

portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours or our 
partners. 

Obtaining  and  maintaining  our  patent  protection  depends  on  compliance  with  various  procedural,  document  submission,  fee 
payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated 
for  non-compliance  with  these  requirements.  Periodic  maintenance  fees,  renewal  fees,  annuity  fees  and  various  other  governmental 
fees  on  patents  and/or  applications  will  be  due  to  be  paid  to  the  USPTO  and  various  governmental  patent  agencies  outside  of  the 
United States in several stages over the lifetime of the patents and/or applications. Non-compliance could result in abandonment or 
lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an 
event, our competitors might be able to enter the market and this circumstance would have a material adverse effect on our business. 

We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property. We rely 
on  intellectual  property  assignment  agreements  with  our  corporate  partners,  employees,  consultants,  scientific  advisors  and  other 
collaborators to grant us ownership of new intellectual property that is developed. These agreements may not result in the effective 
assignment to us of that intellectual property. As a result, our ownership of key intellectual property could be compromised.

We or our licensors may be subject to claims that former employees, collaborators, consultants or other third parties have an 
interest in our owned, co-owned or in-licensed patents, trade secrets, or other intellectual property as an inventor or co-inventor. For 
example,  we  or  our  licensors  may  have  inventorship  disputes  arise  from  conflicting  obligations  of  employees,  collaborators, 
consultants or others who are involved in developing our product candidates. Litigation may be necessary to defend against these and 
other claims challenging inventorship or our or our licensors’ ownership of our owned, co-owned or in-licensed patents, trade secrets 
or other intellectual property. If we or our licensors fail in defending any such claims, in addition to paying monetary damages, we 
may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property that is important to 
our product candidates. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a 
distraction to management and other employees. Any of the foregoing could have a material adverse effect on our business, financial 
condition, results of operations and prospects. 

We  are  a  party  to  license  agreements  and  may  need  to  obtain  additional  licenses  from  others  to  advance  our  research  and 
development activities or allow the commercialization of our drug candidates and future drug candidates we may identify and pursue. 
If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or 
these agreements are terminated or we otherwise experience disruptions to our business relationships with our licensors, we could lose 
intellectual  property  rights  that  are  important  to  our  business.  Our  licensors  might  conclude  that  we  have  materially  breached  our 
obligations  under  such  license  agreements  and  might  therefore  terminate,  or  seek  to  terminate,  the  license  agreements,  thereby 
removing or limiting our ability to develop and commercialize products and technology covered by these license agreements. If our 
license agreements are terminated, we may be required to cease our development and commercialization of our product candidates. 
Any  of  the  foregoing  could  have  a  material  adverse  effect  on  our  competitive  position,  business,  financial  conditions,  results  of 
operations  and  prospects.  Moreover,  disputes  may  arise  regarding  intellectual  property  subject  to  a  licensing  agreement.  The 
resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the 
relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the agreement, 
either  of  which  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of  operations  and  prospects. 
Moreover, if disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing 
arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize the affected product 
candidates.  Any  of  the  foregoing  could  have  a  material  adverse  effect  on  our  competitive  position,  business,  financial  conditions, 
results of operations and prospects.

Changes in either the patent laws or their interpretation in the United States or other countries may diminish the value of our 
intellectual property or our ability to obtain patents. For example, the America Invents Act of 2011 may affect the scope, strength and 
enforceability of our patent rights in the United States or the nature of proceedings which may be brought by us related to our patent 
rights in the United States.

If  one  or  more  products  resulting  from  our  drug  candidates  is  approved  for  sale  by  the  FDA  and  we  do  not  have  adequate 
intellectual property protection for those products, competitors could duplicate them for approval and sale in the United States without 
repeating  the  extensive  testing  required  of  us  or  our  partners  to  obtain  FDA  approval.  Regardless  of  any  patent  protection,  under 
current law, an application for a generic version of a new chemical entity cannot be approved until at least five years after the FDA 
has approved the original product. When that period expires, or if that period is altered, the FDA could approve a generic version of 
our product regardless of our patent protection. An applicant for a generic version of our product may only be required to conduct a 
relatively  inexpensive  study  to  show  that  its  product  is  bioequivalent  to  our  product,  and  may  not  have  to  repeat  the  lengthy  and 
expensive  clinical  trials  that  we  or  our  partners  conducted  to  demonstrate  that  the  product  is  safe  and  effective.  In  the  absence  of 
adequate patent protection for our products in other countries, competitors may similarly be able to obtain regulatory approval in those 
countries of generic versions of our products.

If we are unable to protect the confidentiality of our trade secrets, the value of our technology could be materially adversely 
affected and our business would be harmed. 

27

We  also  rely  on  trade  secrets  to  protect  our  technology,  particularly  where  we  believe  patent  protection  is  not  appropriate  or 
obtainable.  However,  trade  secrets  are  often  difficult  to  protect,  especially  outside  of  the  United  States.  While  we  endeavor  to  use 
reasonable efforts to protect our trade secrets, our or our partners’ employees, consultants, contractors or scientific and other advisors 
may unintentionally or willfully disclose our information to competitors. In addition, confidentiality agreements, if any, executed by 
those individuals may not be enforceable or provide meaningful protection for our trade secrets or other proprietary information in the 
event of unauthorized use or disclosure. We cannot be certain that such agreements have been entered into with all relevant parties, 
and we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed or that competitors 
will  not  otherwise  gain  access  to  our  trade  secrets  or  independently  develop  substantially  equivalent  information  and  techniques. 
Pursuing a claim that a third party had illegally obtained and was using our trade secrets would be expensive and time-consuming, and 
the  outcome  would  be  unpredictable.  Even  if  we  are  able  to  maintain  our  trade  secrets  as  confidential,  if  our  competitors  lawfully 
obtain or independently develop information equivalent or similar to our trade secrets, our business could be harmed.

If we are not able to defend the patent or trade secret protection position of our technologies and drug candidates, then we will 
not be able to exclude competitors from developing or marketing competing drugs, and we may not generate enough revenue from 
product sales to justify the cost of development of our drugs or to achieve or maintain profitability.

If we are sued for infringing third-party intellectual property rights, it will be costly and time-consuming, and an unfavorable 
outcome could have a significant adverse effect on our business.

Our ability to commercialize drugs depends on our ability to use, manufacture and sell those drugs without infringing the patents 
or other proprietary rights of third parties. Numerous U.S. and foreign issued patents and pending patent applications owned by third 
parties  exist  in  the  therapeutic  areas  in  which  we  are  developing  drug  candidates  and  seeking  new  potential  drug  candidates.  In 
addition,  because  patent  applications  can  take  several  years  to  issue,  there  may  be  currently  pending  applications,  unknown  to  us, 
which  could  later  result  in  issued  patents  that  our  activities  with  our  drug  candidates  could  infringe.  There  may  also  be  existing 
patents, unknown to us, that our activities with our drug candidates could infringe.

Other  future  products  of  ours  may  be  impacted  by  patents  of  companies  engaged  in  competitive  programs  with  significantly 

greater resources. Further development of these products could be impacted by these patents and result in significant legal fees.

If a third party claims that our actions infringe its patents or other proprietary rights, we could face a number of issues that could 

seriously harm our competitive position, including, but not limited to:

•

•

•

•

infringement and other intellectual property claims that, even if meritless, can be costly and time-consuming to litigate, 
delay the regulatory approval process and divert management’s attention from our core business operations;
substantial damages for past infringement which we may have to pay if a court determines that our drugs or technologies 
infringe a third party’s patent or other proprietary rights;
a  court  prohibiting  us  from  selling  or  licensing  our  drugs  or  technologies  unless  the  holder  licenses  the  patent  or  other 
proprietary rights to us, which it is not required to do; and
if a license is available from a holder, we may have to pay substantial royalties or grant cross-licenses to our patents or 
other proprietary rights.

If any of these events occur, it could significantly harm our business and negatively affect our stock price.

We may undertake infringement or other legal proceedings against third parties, causing us to spend substantial resources on 
litigation and exposing our own intellectual property portfolio to challenge.

Third  parties  may  infringe  our  patents.  To  prevent  infringement  or  unauthorized  use,  we  may  need  to  file  infringement  suits, 
which  are  expensive  and  time-consuming.  In  an  infringement  proceeding,  a  court  may  decide  that  one  or  more  of  our  patents  is 
invalid, unenforceable, or both. In such case third parties may be able to use our technology without paying licensing fees or royalties. 
Even  if  the  validity  of  our  patents  is  upheld,  a  court  may  refuse  to  stop  the  other  party  from  using  the  technology  at  issue  on  the 
ground  that  the  other  party’s  activities  are  not  covered  by  our  patents.  Policing  unauthorized  use  of  our  intellectual  property  is 
difficult, and we may not be able to prevent misappropriation of our proprietary rights, particularly in countries where the laws may 
not protect such rights as fully as in the United States. In addition, third parties may affirmatively challenge our rights to, or the scope 
or validity of, our patent rights.

The uncertainties associated with litigation could have a material adverse effect on our ability to raise the funds necessary to 
conduct  clinical  trials,  continue  our  research  programs,  license  necessary  technology  from  third  parties,  or  enter  into  development 
partnerships that would help us bring our drug candidates or other product candidates that we may identify to market. Furthermore, 
because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of 
our  confidential  information  could  be  compromised  by  disclosure  during  this  type  of  litigation.  There  could  also  be  public 
announcements of the results of hearings, motions, or other interim proceedings or developments. If securities analysts or investors 
perceive these results to be negative, it could have a material adverse effect on the price of our common stock.

28

We may become involved in disputes with our strategic partners over intellectual property ownership, and publications by our 
research collaborators and clinical investigators could impair our ability to obtain patent protection or protect our proprietary 
information, either of which would have a significant impact on our business.

Inventions  discovered  under  our  current  or  future  strategic  alliance  agreements  may  become  jointly  owned  by  our  strategic 
partners and us in some cases, and the exclusive property of one of us in other cases. Under some circumstances, it may be difficult to 
determine who owns a particular invention or whether it is jointly owned, and disputes could arise regarding ownership or use of those 
inventions. These disputes could be costly and time-consuming, and an unfavorable outcome could have a significant adverse effect 
on our business if we were not able to protect or license rights to these inventions. In addition, our research collaborators and clinical 
investigators generally have contractual rights to publish data arising from their work. Publications by our research collaborators and 
clinical investigators relating to our research and development programs, either with or without our consent, could benefit our current 
or  potential  competitors  and  may  impair  our  ability  to  obtain  patent  protection  or  protect  our  proprietary  information,  which  could 
significantly harm our business.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed 
confidential  information  of  third  parties  or  that  we  or  our  employees  have  wrongfully  used  or  disclosed  trade  secrets  of  their 
former employers.

Many  of  our  employees  were  previously  employed  at  universities  or  other  biotechnology  or  pharmaceutical  companies, 
including our competitors or potential competitors. Although no legal proceedings against us are currently pending, we may be subject 
to claims that these employees or we have inadvertently or otherwise used or disclosed trade secrets or other proprietary information 
of their former employers. Litigation may be necessary to defend against these claims. If we fail in defending these claims, in addition 
to paying monetary damages, we may lose valuable intellectual property rights or personnel. A loss of key research personnel or their 
work  product  could  hamper  or  prevent  our  ability  to  develop  and  commercialize  certain  potential  drugs,  which  could  significantly 
harm our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and distract 
management.

Our  competitors  may  develop  drugs  that  are  less  expensive,  safer  or  more  effective  than  ours,  which  may  diminish  or 

eliminate the commercial success of any drugs that we may commercialize.

We compete with companies that have developed drugs or are developing drug candidates for cardiovascular diseases, diseases 
and  conditions  associated  with  muscle  weakness  or  wasting  and  other  diseases  for  which  our  drug  candidates  may  be  useful 
treatments. For example, if reldesemtiv is approved for marketing by the FDA or other regulatory authorities for the treatment of ALS, 
it will then compete with RADICAVATM (edaravone), the first FDA approved drug for the treatment of ALS since riluzole in 1995, 
and may then compete with other potential new therapies for ALS that are currently being developed by companies including, but not 
limited to, Neuraltus Pharmaceuticals, Inc., Ionis Pharmaceuticals, Inc. (in collaboration with Biogen Inc.), AB Science, Mitsubishi 
Tanabe Pharma Corporation, Treeway, Genentech, Inc., and BrainStorm Cell Therapeutics.  Also, if reldesemtiv is approved by the 
FDA  or  other  regulatory  authorities  for  the  treatment  of  SMA,  it  will  then  compete  with  SPINRAZA®  (nusinersen)  and  may  then 
compete with other potential new therapies being developed by companies including, but not limited to, Roche (in collaboration with 
PTC Therapeutics) and AveXis, Inc. (a Novartis company). If reldesemtiv is approved by the FDA or other regulatory authorities for 
the  treatment  of  non-neuromuscular  indications  associated  with  muscle  weakness,  it  may  then  compete  with  other  potential  new 
therapies being developed by companies including, but not limited to, Regeneron Pharmaceuticals, Inc. (in collaboration with Sanofi), 
Eli Lilly and Company, Acceleron Pharma, Stealth Biotherapeutics, and Novartis (in collaboration with MorphoSys AG).

If omecamtiv mecarbil is approved for marketing by the FDA or other regulatory authorities for the treatment of heart failure, it 
would  compete  against  other  drugs  used  for  the  treatment  of  acute  and  chronic  heart  failure.  These  include  generic  drugs,  such  as 
milrinone,  dobutamine  or  digoxin  and  branded  drugs  such  as  Natrecor®  (nesiritide),  Corlanor®  (ivabradine),  and  Entresto® 
(sacubitril/valsartan).  Omecamtiv  mecarbil  could  also  potentially  compete  against  other  novel  drug  candidates  and  therapies  in 
development,  such  as  those  being  developed  by,  but  not  limited  to,  Novartis,  Bayer,  Stealth  Biotherapeutics,  and  MyoKardia.  In 
addition, there are a number of medical devices both marketed and in development for the potential treatment of heart failure.

Our competitors may:
•
•
•
•
•
•
•

develop drug candidates and market drugs that are less expensive or more effective than our future drugs;
commercialize competing drugs before we or our partners can launch any drugs developed from our drug candidates;
hold or obtain proprietary rights that could prevent us from commercializing our products;
initiate or withstand substantial price competition more successfully than we can;
more successfully recruit skilled scientific workers and management from the limited pool of available talent;
more effectively negotiate third-party licenses and strategic alliances;
take advantage of acquisition or other opportunities more readily than we can;

29

•

•

develop drug candidates and market drugs that increase the levels of safety or efficacy that our drug candidates will need 
to show in order to obtain regulatory approval; or
introduce therapies or market drugs that render the market opportunity for our potential drugs obsolete.

We will compete for market share against large pharmaceutical and biotechnology companies and smaller companies that are 
collaborating with larger pharmaceutical companies, new companies, academic institutions, government agencies and other public and 
private  research  organizations.  Many  of  these  competitors,  either  alone  or  together  with  their  partners,  may  develop  new  drug 
candidates that will compete with ours. Many of these competitors have larger research and development programs or substantially 
greater financial resources than we do. Our competitors may also have significantly greater experience in:

•
•
•
•
•

•

developing drug candidates;
undertaking preclinical testing and clinical trials;
building relationships with key customers and opinion-leading physicians;
obtaining and maintaining FDA and other regulatory approvals of drug candidates;
formulating and manufacturing drugs; and

launching, marketing and selling drugs.

If  our  competitors  market  drugs  that  are  less  expensive,  safer  or  more  efficacious  than  our  potential  drugs,  or  that  reach  the 
market sooner than our potential drugs, we may not achieve commercial success. In addition, the life sciences industry is characterized 
by rapid technological change. If we fail to stay at the forefront of technological change, we may be unable to compete effectively. 
Our competitors may render our technologies obsolete by improving existing technological approaches or developing new or different 
approaches,  potentially  eliminating  the  advantages  in  our  drug  discovery  process  that  we  believe  we  derive  from  our  research 
approach and proprietary technologies.

We have been granted orphan designation in the U.S. for reldesemtiv; however, there can be no guarantee that we will receive 
orphan approval for reldesemtiv, nor that we will be able to prevent third parties from developing and commercializing products 
that are competitive to reldesemtiv.

We have been granted orphan drug designation in the U.S. by the FDA for reldesemtiv for the potential treatment of SMA. In 
the U.S., upon approval from the FDA of an NDA, products granted orphan drug designation are generally provided with seven years 
of  marketing  exclusivity  in  the  U.S.,  meaning  the  FDA  will  generally  not  approve  applications  for  other  product  candidates  that 
contain the same active ingredient for the same orphan indication. Even if we are the first to obtain approval of an orphan product and 
are granted such exclusivity in the U.S., there are limited circumstances under which a later competitor product may be approved for 
the  same  indication  during  the  seven-year  period  of  marketing  exclusivity,  such  as  if  the  later  product  is  shown  to  be  clinically 
superior to our product or due to an inability to assure a sufficient quantity of the orphan drug.

Orphan medicinal product status in the Europe Union can provide up to 10 years of marketing exclusivity, meaning that another 
application for marketing authorization of a later similar medicinal product for the same therapeutic indication will generally not be 
approved  in  the  European  Union.  Although  we  may  have  drug  candidates  that  may  obtain  orphan  drug  exclusivity  in  Europe,  the 
orphan approval and associated exclusivity period may be modified for several reasons, including a significant change to the orphan 
medicinal  product  designations  or  approval  criteria  after-market  authorization  of  the  orphan  product  (e.g.,  product  profitability 
exceeds the criteria for orphan drug designation), problems with the production or supply of the orphan drug or a competitor drug, 
although similar, is safer, more effective or otherwise clinically superior than the initial orphan drug.

We  are  not  guaranteed  to  maintain  orphan  status  for  reldesemtiv  or  to  receive  orphan  status  for  reldesemtiv  for  any  other 
indication or for any of our other drug candidates for any indication. If our drug candidates that are granted orphan status were to lose 
their status as orphan drugs or the marketing exclusivity provided for them in the U.S. or the European Union, our business and results 
of  operations  could  be  materially  adversely  affected.  While  orphan  status  for  any  of  our  products,  if  granted  or  maintained,  would 
provide market exclusivity in the U.S. and the European Union for the time periods specified above, we would not be able to exclude 
other  companies  from  manufacturing  and/or  selling  products  using  the  same  active  ingredient  for  the  same  indication  beyond  the 
exclusivity period applicable to our product on the basis of orphan drug status. Moreover, we cannot guarantee that another company 
will not receive approval before we do of an orphan drug application in the U.S. or the European Union for a product candidate that 
has the same active ingredient or is a similar medicinal product for the same indication as any of our drug candidates for which we 
plan  to  file  for  orphan  designation  and  status.  If  that  were  to  happen,  our  orphan  drug  applications  for  our  drug  candidate  for  that 
indication may not be approved until the competing company’s period of exclusivity has expired in the U.S. or the European Union, as 
applicable.  Further,  application  of  the  orphan  drug  regulations  in  the  U.S.  and  Europe  is  uncertain,  and  we  cannot  predict  how the 
respective regulatory bodies will interpret and apply the regulations to our or our competitors’ products.

Our  failure  to  attract  and  retain  skilled  personnel  could  impair  our  drug  development,  commercialization  and  financial 
reporting activities.

Our business depends on the performance of our senior management and key scientific and technical personnel. The loss of the 
services of any member of our senior management or key scientific, technical or financial reporting staff may significantly delay or 
prevent the achievement of drug development and other business objectives by diverting management’s attention to transition matters 
and  identifying  suitable  replacements.  For  example,  our  management  concluded  that  our  internal  controls  over  financial  reporting 
were not effective as of December 31, 2018 because an unremediated material weakness existed in our internal control over financial 
reporting related to employee turnover resulting in a temporary lack of resources in financial reporting roles with the appropriate skills 
to  perform  effective  review  during  our  financial  statement  close  process.  We  also  rely  on  consultants  and  advisors  to  assist  us  in 
formulating our research and development strategy. All of our consultants and advisors are either self-employed or employed by other 
organizations,  and  they  may  have  conflicts  of  interest  or  other  commitments,  such  as  consulting  or  advisory  contracts  with  other 
organizations,  that  may  affect  their  ability  to  contribute  to  us.  In  addition,  if  and  as  our  business  grows,  we  will  need  to  recruit 
additional executive management and scientific, technical and financial reporting personnel. There is intense competition for skilled 
executives and employees with relevant scientific and technical expertise, and this competition is likely to continue. Our inability to 
attract  and  retain  sufficient  scientific,  technical  and  managerial  personnel  could  limit  or  delay  our  product  development  activities, 
which would adversely affect the development of our drug candidates and commercialization of our potential drugs and growth of our 
business.

Any future workforce and expense reductions may have an adverse impact on our internal programs and our ability to hire and 
retain skilled personnel.

Our  future  success  will  depend  in  large  part  upon  our  ability  to  attract  and  retain  highly  skilled  personnel.  In  light  of  our 
continued need for funding and cost control, we may be required to implement future workforce and expense reductions, which could 
further limit our research and development activities. We may have difficulty retaining and attracting such personnel as a result of a 
perceived  risk  of  future  workforce  reductions.  In  addition,  the  implementation  of  any  additional  workforce  or  expense  reduction 
programs may divert the efforts of our management team and other key employees, which could adversely affect our business.

We may expand our development and clinical research capabilities and, as a result, we may encounter difficulties in managing 
our growth, which could disrupt our operations.

We  may  have  growth  in  our  expenditures,  the  number  of  our  employees  and  the  scope  of  our  operations,  in  particular  with 
respect to those drug candidates that we elect to develop or commercialize independently or together with a partner. To manage our 
anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our 
facilities  and  continue  to  recruit  and  train  additional  qualified  personnel.  Due  to  our  limited  resources,  we  may  not  be  able  to 
effectively manage the expansion of our operations or recruit and train additional qualified personnel. The physical expansion of our 
operations may lead to significant costs and may divert our management and business development resources. Any inability to manage 
growth could delay the execution of our business plans or disrupt our operations.

We  currently  have  no  sales  or  marketing  capabilities  and,  if  we  are  unable  to  enter  into  or  maintain  strategic  alliances  with 
marketing partners or to develop our own sales and marketing capabilities, we may not be successful in commercializing our 
potential drugs.

We  currently  have  no  sales,  marketing  or  distribution  capabilities.  We  plan  to  commercialize  drugs  that  can  be  effectively 
marketed and sold in concentrated markets that do not require a large sales force to be competitive. To achieve this goal, we will need 
to  establish  our  own  specialized  sales  force  and  marketing  organization  with  technical  expertise  and  supporting  distribution 
capabilities. Developing such an organization is expensive and time-consuming and could delay a product launch. In addition, we may 
not be able to develop this capacity efficiently, cost-effectively or at all, which could make us unable to commercialize our drugs. If 
we  determine  not  to  market  our  drugs  on  our  own,  we  will  depend  on  strategic  alliances  with  third  parties,  such  as  Amgen  and 
Astellas, which have established distribution systems and direct sales forces to commercialize them. If we are unable to enter into such 
arrangements  on  acceptable  terms,  we  may  not  be  able  to  successfully  commercialize  these  drugs.  To  the  extent  that  we  are  not 
successful in commercializing any drugs ourselves or through a strategic alliance, our product revenues and business will suffer and 
our stock price would decrease.

Our internal computer systems, or those of our CROs, CMOs, supply chain partners, collaboration partners or other contractors 
or  consultants,  may  fail  or  suffer  security  breaches,  which  could  result  in  a  material  disruption  of  our  drug  development 
programs.

Despite the implementation of security measures, our internal computer systems and those of our third-party contract research 
organizations (“CROs”), CMOs, supply chain partners, collaboration partners and other contractors and consultants are vulnerable to 
damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failures. If 
such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our drug development 
programs. For example, the loss of clinical study data from completed or ongoing clinical studies for any of our drug candidates could 
result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent 

31

that any disruption or security breach were to result in a loss of or damage to our data or applications, or inappropriate disclosure of 
confidential or proprietary information, we could incur liability, our operations could be compromised and the further development of 
our product candidates could be delayed.

Significant disruptions of information technology systems or breaches of data security could adversely affect our business.

Our  business  is  increasingly  dependent  on  complex  and  interdependent  information  technology  systems,  including  internet-
based systems, databases and programs, to support our business processes as well as internal and external communications. As use of 
information technology systems has increased, deliberate attacks and attempts to gain unauthorized access to computer systems and 
networks  have  increased  in  frequency  and  sophistication.  Our  information  technology,  systems  and  networks  are  potentially 
vulnerable  to  breakdown,  malicious  intrusion  and  computer  viruses  which  may  result  in  the  impairment  of  production  and  key 
business processes or loss of data or information. We are also potentially vulnerable to data security breaches—whether by employees 
or others—which may expose sensitive data to unauthorized persons. We have in the past and may in the future be subject to security 
breaches. For example, in February 2018, we discovered that our e-mail server suffered unauthorized intrusions in which proprietary 
business  information  was  accessed.  Although  we  do  not  believe  that  we  have  experienced  any  material  losses  related  to  security 
breaches,  including  a  recent  cybersecurity  incident,  there  can  be  no  assurance  that  we  will  not  suffer  such  losses  in  the  future. 
Breaches and other inappropriate access can be difficult to detect and any delay in identifying them could increase their harm. While 
we  have  implemented  security  measures  to  protect  our  data  security  and  information  technology  systems,  such  measures  may  not 
prevent  such  events.  Any  such  breaches  of  security  and  inappropriate  access  could  disrupt  our  operations,  harm  our  reputation  or 
otherwise have a material adverse effect on our business, financial condition and results of operations.

Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the U.S.

We prepare our financial statements in conformity with accounting principles generally accepted in the U.S. These accounting 
principles  are  subject  to  interpretation  by  the  Financial  Accounting  Standards  Board  (“FASB”)  and  the  SEC.  A  change  in  these 
policies or interpretations could have a significant effect on our reported financial results, may retroactively affect previously reported 
results,  could  cause  unexpected  financial  reporting  fluctuations,  and  may  require  us  to  make  costly  changes  to  our  operational 
processes and accounting systems. 

Our  revenue  to  date  has  been  primarily  derived  from  our  research  and  license  agreements,  which  can  result  in  significant 
fluctuation  in  our  revenue  from  period  to  period,  and  our  past  revenue  is  therefore  not  necessarily  indicative  of  our  future 
revenue.

Our  revenue  is  primarily  derived  from  our  research  and  license  agreements,  from  which  we  receive  upfront  fees,  contract 
research payments, milestone and other contingent payments based on clinical progress, regulatory progress or net sales achievements 
and  royalties.  Significant  variations  in  the  timing  of  receipt  of  cash  payments  and  our  recognition  of  revenue  can  result  from 
significant  payments  based  on  the  execution  of  new  research  and  license  agreements,  the  timing  of  clinical  outcomes,  regulatory 
approval, commercial launch or the achievement of certain annual sales thresholds. The amount of our revenue derived from research 
and  license  agreements  in  any  given  period  will  depend  on  a  number  of  unpredictable  factors,  including  our  ability  to  find  and 
maintain suitable collaboration partners, the timing of the negotiation and conclusion of collaboration agreements with such partners, 
whether  and  when  we  or  our  collaboration  partners  achieve  clinical,  regulatory  and  sales  milestones,  the  timing  of  regulatory 
approvals in one or more major markets, reimbursement levels by private and government payers, and the market introduction of new 
drugs  or  generic  versions  of  the  approved  drug,  as  well  as  other  factors.  Our  past  revenue  generated  from  these  agreements  is  not 
necessarily indicative of our future revenue. If any of our existing or future collaboration partners fails to develop, obtain regulatory 
approval  for,  manufacture  or  ultimately  commercialize  any  product  candidate  under  our  collaboration  agreement,  our  business, 
financial condition, and results of operations could be materially and adversely affected. 

Indebtedness under our Loan Agreement bears interest at variable interest rates based on LIBOR. Changes in the method of 
determining LIBOR, or the replacement of LIBOR with an alternative reference rate, may adversely affect interest rates on our 
current or future indebtedness and may otherwise adversely affect our financial condition and results of operations.

In  July  2017,  the  Financial  Conduct  Authority,  the  authority  that  regulates  LIBOR,  announced  that  it  intended  to  stop 
compelling banks to submit rates for the calculation of LIBOR after 2021. The Alternative Reference Rates Committee (“ARRC”) in 
the U.S. has proposed that the Secured Overnight Financing Rate (“SOFR”) is the rate that represents best practice as the alternative to 
the U.S. dollar LIBOR for use in derivatives and other financial contracts that are currently indexed to LIBOR. ARRC has proposed a 
paced  market  transition  plan  to  SOFR  from  U.S.  dollar  LIBOR  and  organizations  are  currently  working  on  industry-wide  and 
company-specific transition plans as relating to derivatives and cash markets exposed to U.S. dollar LIBOR. We have certain financial 
contracts, including the Loan Agreement, that are indexed to U.S. dollar LIBOR. Changes in the method of determining LIBOR, or 
the replacement of LIBOR with an alternative reference rate, may adversely affect interest rates on our current or future indebtedness. 
Any  transition  process  may  involve,  among  other  things,  increased  volatility  or  illiquidity  in  markets  for  instruments  that  rely 
on LIBOR,  reductions  in  the  value  of  certain  instruments  or  the  effectiveness  of  related  transactions  such  as  hedges,  increased 
borrowing  costs,  uncertainty  under  applicable  documentation,  or  difficult  and  costly  consent  processes.  We  are  monitoring  this 
activity and evaluating the related risks, and any such effects of the transition away from LIBOR may result in increased expenses, 
may impair our ability to refinance our indebtedness or hedge our exposure to floating rate instruments, or may result in difficulties, 

32

complications or delays in connection with future financing efforts, any of which could adversely affect our financial condition and 
results of operations.

Risks Related To Our Industry

The  regulatory  approval  process  is  expensive,  time-consuming  and  uncertain  and  may  prevent  our  partners  or  us  from 
obtaining approvals to commercialize some or all of our drug candidates.

The research, testing, manufacturing, selling and marketing of drugs are subject to extensive regulation by the FDA and other 
regulatory  authorities  in  the  United  States  and  other  countries,  and  regulations  differ  from  country  to  country.  Neither  we  nor  our 
partners are permitted to market our potential drugs in the United States until we receive approval of a new drug application (“NDA”) 
from the FDA. Neither we nor our partners have received NDA or other marketing approval for any of our drug candidates.

Obtaining  NDA  approval  is  a  lengthy,  expensive  and  uncertain  process.  In  addition,  failure  to  comply  with  FDA  and  other 
applicable foreign and U.S. regulatory requirements may subject us to administrative or judicially imposed sanctions. These include 
warning  letters,  civil  and  criminal  penalties,  injunctions,  product  seizure  or  detention,  product  recalls,  total  or  partial  suspension  of 
production, and refusal to approve pending NDAs or supplements to approved NDAs.

Regulatory approval of an NDA or NDA supplement is never guaranteed, and the approval process typically takes several years 
and is extremely expensive. The FDA and foreign regulatory agencies also have substantial discretion in the drug approval process, 
and the guidance and advice issued by such agencies is subject to change at any time. Despite the time and efforts exerted, failure can 
occur  at  any  stage,  and  we  may  encounter  problems  that  cause  us  to  abandon  clinical  trials  or  to  repeat  or  perform  additional 
preclinical testing and clinical trials. The number and focus of preclinical studies and clinical trials that will be required for approval 
by the FDA and foreign regulatory agencies varies depending on the drug candidate, the disease or condition that the drug candidate is 
designed to address, and the regulations applicable to any particular drug candidate. In addition, the FDA may require that a proposed 
Risk  Evaluation  and  Mitigation  Strategy  (“REMS”)  be  submitted  as  part  of  an  NDA  if  the  FDA  determines  that  it  is  necessary  to 
ensure that the benefits of the drug outweigh its risks. The FDA and foreign regulatory agencies can delay, limit or deny approval of a 
drug candidate for many reasons, including, but not limited to:

•

•

•

•

they might determine that a drug candidate is not safe or effective;

they might not find the data from non-clinical testing and clinical trials sufficient and could request that additional trials 
be performed;

they might not approve our, our partner’s or the contract manufacturer’s processes or facilities; or

they might change their approval policies or adopt new regulations.

Even if we receive regulatory approval to manufacture and sell a drug in a particular regulatory jurisdiction, other jurisdictions’ 
regulatory authorities may not approve that drug for manufacture and sale. If we or our partners fail to receive and maintain regulatory 
approval for the sale of any drugs resulting from our drug candidates, it would significantly harm our business and negatively affect 
our stock price.

If we or our partners receive regulatory approval for our drug candidates, we or they will be subject to ongoing obligations to 
and  continued  regulatory  review  by  the  FDA  and  foreign  regulatory  agencies,  and  may  be  subject  to  additional  post-marketing 
obligations, all of which may result in significant expense and limit commercialization of our potential drugs.

 Any regulatory approvals that we or our partners receive for our drug candidates may be subject to limitations on the indicated 
uses for which the drug may be marketed or require potentially costly post-marketing follow-up studies or compliance with a REMS. 
In  addition,  if  the  FDA  or  foreign  regulatory  agencies  approves  any  of  our  drug  candidates,  the  labeling,  packaging,  adverse  event 
reporting, storage, advertising, promotion and record-keeping for the drug will be subject to extensive regulatory requirements. The 
subsequent discovery of previously unknown problems with the drug, including adverse events of unanticipated severity or frequency, 
or  the  discovery  that  adverse  events  or  toxicities  observed  in  preclinical  research  or  clinical  trials  that  were  believed  to  be  minor 
constitute much more serious problems, may result in restrictions on the marketing of the drug or withdrawal of the drug from the 
market.

The FDA and foreign regulatory agencies may change their policies and additional government regulations may be enacted that 
could  prevent  or  delay  regulatory  approval  of  our  drug  candidates.  We  cannot  predict  the  likelihood,  nature  or  extent  of  adverse 
government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are 
not able to maintain regulatory compliance, we might not be permitted to market our drugs and our business would suffer.

33

If physicians and patients do not accept our drugs, we may be unable to generate significant revenue, if any.

Even  if  our  drug  candidates  obtain  regulatory  approval,  the  resulting  drugs,  if  any,  may  not  gain  market  acceptance  among 
physicians, healthcare payors, patients and the medical community. Even if the clinical safety and efficacy of drugs developed from 
our  drug  candidates  are  established  for  purposes  of  approval,  physicians  may  elect  not  to  recommend  these  drugs  for  a  variety  of 
reasons including, but not limited to:

•

•

•

•

•

•

•

•

introduction of competitive drugs to the market;

clinical safety and efficacy of alternative drugs or treatments;

cost-effectiveness;

availability of coverage and reimbursement from health maintenance organizations and other third-party payors;

convenience and ease of administration;

prevalence and severity of adverse events;

other potential disadvantages relative to alternative treatment methods; or

insufficient marketing and distribution support.

If  our  drugs  fail  to  achieve  market  acceptance,  we  may  not  be  able  to  generate  significant  revenue  and  our  business  would 

suffer.

Recently  enacted  and  future  legislation,  including  potentially  unfavorable  pricing  regulations  or  other  healthcare  reform 
initiatives,  may  increase  the  difficulty  and  cost  for  us  to  obtain  regulatory  approval  of  and  commercialize  our  product 
candidates and affect the prices we may obtain.

The  regulations  that  govern,  among  other  things,  regulatory  approvals,  coverage,  pricing  and  reimbursement  for  new  drug 
products  vary  widely  from  country  to  country.  In  the  United  States  and  some  foreign  jurisdictions,  there  have  been  a  number  of 
legislative  and  regulatory  changes  and  proposed  changes  regarding  the  healthcare  system  that  could  prevent  or  delay  regulatory 
approval of our product candidates, restrict or regulate post-approval activities and affect our ability to successfully sell any product 
candidates for which we obtain regulatory approval. In particular, in March 2010, the Patient Protection and Affordable Care Act, as 
amended by the Health Care and Education Reconciliation Act (collectively, the “ACA”) was enacted, which substantially changes 
the  way  health  care  is  financed  by  both  governmental  and  private  insurers,  and  significantly  impacts  the  U.S.  pharmaceutical 
industry.  The ACA and its implementing regulations, among other things, addressed a new methodology by which rebates owed by 
manufacturers  under  the  Medicaid  Drug  Rebate  Program  are  calculated  for  certain  drugs  and  biologics,  including  our  product 
candidates that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates owed by manufacturers 
under the Medicaid Drug Rebate Program, extended the Medicaid Drug Rebate Program to utilization of prescriptions of individuals 
enrolled  in  Medicaid  managed  care  organizations,  subjected  manufacturers  to  new  annual  fees  and  taxes  for  certain  branded 
prescription  drugs,  provided  incentives  to  programs  that  increase  the  federal  government’s  comparative  effectiveness  research  and 
established a new Medicare Part D coverage gap discount program.

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted. In August 2011, the 
Budget  Control  Act  of  2011,  among  other  things,  created  measures  for  spending  reductions  by  the  U.S.  Congress.  A  Joint  Select 
Committee  on  Deficit  Reduction,  tasked  with  recommending  a  targeted  deficit  reduction  of  at  least  $1.2  trillion  for  the  years  2013 
through  2021,  was  unable  to  reach  required  goals,  thereby  triggering  the  legislation’s  automatic  reduction  to  several  government 
programs. This includes aggregate reductions of Medicare payments to providers of 2% per fiscal year, which went into effect in April 
2013,  and,  due  to  subsequent  legislative  amendments,  will  remain  in  effect  through  2027  unless  additional  Congressional  action is 
taken. In January 2013, the American Taxpayer Relief Act of 2012 was enacted which, among other things, further reduced Medicare 
payments  to  several  providers,  including  hospitals  and  outpatient  clinics,  and  increased  the  statute  of  limitations  period  for  the 
government to recover overpayments to providers from three to five years.

Since its enactment, there have been judicial and Congressional challenges to numerous elements of the ACA, as well as efforts 
by  both  the  executive  and  legislative  branches  of  the  federal  government  to  repeal  or  replace  certain  aspects  of  the  ACA.  For 
example, the President signed Executive Orders designed to delay the implementation of certain provisions of the ACA or otherwise 
circumvent  some  of  the  requirements  for  health  insurance  mandated  by  the  ACA. In  addition,  the  U.S.  Congress  has  considered 
legislation  that  would  repeal  or  repeal  and  replace  all  or  part  of  the  ACA.  While  the  U.S.  Congress  has  not  passed  comprehensive 
repeal legislation, it has enacted laws that modify certain provisions of the ACA, such as removing penalties, starting January 1, 2019, 
for  not  complying  with  the  ACA’s  individual  mandate  to  carry  health  insurance,  delaying  the  implementation  of  certain  mandated 
fees, and increasing the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D. In 
December  2018,  a  Texas  U.S.  District  Court  Judge  ruled  that  the  ACA  is  unconstitutional  in  its  entirety  because  the  “individual 
mandate”  was  repealed  by  Congress  as  part  of  the  Tax  Cuts  and  Jobs  Act  of  2017,  or  the  Tax  Act.  The  Texas  U.S.  District  Court 
Judge,  as  well  as  the  presidential  administration  and  the  CMS,  have  stated  that  the  ruling  will  have  no  immediate  effect  pending 
appeal of the decision, but it is unclear how this decision, subsequent appeals, and other efforts to repeal and replace the ACA will 
impact  the  ACA  and  our  business.  The  U.S.  Congress  may  consider and  adopt  other  legislation  to  repeal  and  replace  all  or  certain 

34

elements of the ACA. Any other executive, legislative or judicial action to “repeal and replace” all or part of the ACA may have the 
effect of limiting the amounts that government agencies will pay for healthcare products and services, which could result in reduced 
demand for our products or additional pricing pressure, or may lead to significant deregulation, which could make the introduction of 
competing  products  and  technologies  much  easier.  Policy  changes,  including  potential  modification  or  repeal  of  all  or  parts  of  the 
ACA or the implementation of new health care legislation, could result in significant changes to the health care system which may 
adversely affect our business in unpredictable ways.

There  have  been,  and  likely  will  continue  to  be,  legislative  and  regulatory  proposals  at  the foreign,  federal  and  state  levels 
directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. We cannot predict the initiatives 
that may be adopted in the future. The continuing efforts of governments, insurance companies, managed care organizations and other 
payors of healthcare services to contain or reduce costs of healthcare, including by imposing price controls, may adversely affect the 
demand for our product candidates for which we obtain regulatory approval and our ability to set a price that we believe is fair for our 
products. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments 
from private payors.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional 
activities for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA 
or foreign regulations, guidance or interpretations will be changed, or what the impact of these changes on the regulatory approvals of 
our  product  candidates,  if  any,  may  be.  In  the  United  States,  the  European  Union  and  other  potentially  significant  markets  for our 
product candidates, government authorities and third-party payors are increasingly attempting to limit or regulate the price of medical 
products and services, particularly for new and innovative products and therapies, which has resulted in lower average selling prices. 
For example, in the United States, there have been several recent Congressional inquiries and proposed and enacted federal and state 
legislation  designed  to,  among  other  things,  bring  more  transparency  to  drug  pricing,  review  the  relationship  between  pricing  and 
manufacturer patient programs, and reform government program reimbursement methodologies for drugs. Additionally, in May 2018, 
the U.S. presidential administration laid out a “Blueprint” to lower drug prices and reduce out of pocket costs of drugs that contains 
additional  proposals  to  increase  manufacturer  competition,  increase  the  negotiating  power  of  certain  federal  healthcare  programs, 
incentivize  manufacturers  to  lower  the  list  price  of  their  products  and  reduce  the  out  of  pocket  costs  of  drug  products  paid  by 
consumers. The U.S. Department of Health and Human Services (“HHS”) has started the process of soliciting feedback on some of 
these  measures  and,  at  the  same  time,  is  immediately  implementing  others  under  its  existing  authority.  In  January  2019,  the  HHS 
Office of Inspector General proposed modifications to U.S. federal healthcare Anti-Kickback Statute safe harbors which, among other 
things, will affect rebates paid by manufacturers to Medicare Part D plans, the purpose of which is to further reduce the cost of drug 
products  to  consumers.  Although  some  of  these  and  other  proposals  may  require  authorization  through  additional  legislation  to 
become  effective,  members  of  Congress  and  the  presidential  administration  have  indicated  that  they  will  continue  to  seek  new 
legislative  or  administrative  measures  to  control  drug  costs. At  the  state  level,  legislatures  have  increasingly  passed  legislation  and 
implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement 
constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some 
cases,  to  encourage  importation  from  other  countries  and  bulk  purchasing. Furthermore,  the  increased  emphasis  on  managed 
healthcare  in  the  United  States  and  on  country  and  regional  pricing  and  reimbursement  controls  in  the  European  Union  will  put 
additional  pressure  on  product  pricing,  reimbursement  and  usage,  which  may  adversely  affect  our  future  product  sales.  These 
pressures can arise from rules and practices of managed care groups, judicial decisions and governmental laws and regulations related 
to Medicare, Medicaid and healthcare reform, pharmaceutical reimbursement policies and pricing in general.

In addition, there is significant uncertainty regarding the reimbursement status of newly approved healthcare products. We may 
need  to  conduct  expensive  pharmacoeconomic  studies  in  order  to  demonstrate  the  cost-effectiveness  of  our  products.  If  third-party 
payors  do  not  consider  our  products  to  be  cost-effective  compared  to  other  therapies,  the  payors  may  not  cover  our  products  after 
approved as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our products on a 
profitable basis.

We may be subject to costly product liability or other liability claims and may not be able to obtain adequate insurance.

The  use  of  our  drug  candidates  in  clinical  trials  may  result  in  adverse  events.  We  cannot  predict  all  the  possible  harms  or 
adverse events that may result from our clinical trials. We currently maintain limited product liability insurance. We may not have 
sufficient resources to pay for any liabilities resulting from a personal injury or other claim excluded from, or beyond the limit of, our 
insurance coverage. Our insurance does not cover third-parties’ negligence or malpractice, and our clinical investigators and sites may 
have inadequate insurance or none at all. In addition, in order to conduct clinical trials or otherwise carry out our business, we may 
have to contractually assume liabilities for which we may not be insured. If we are unable to look to our own insurance or a third-
party’s insurance to pay claims against us, we may have to pay any arising costs and damages ourselves, which may be substantial.

In  addition,  if  we  commercially  launch  drugs  based  on  our  drug  candidates,  we  will  face  even  greater  exposure  to  product 
liability  claims.  This  risk  exists  even  with  respect  to  those  drugs  that  are  approved  for  commercial  sale  by  the  FDA  and  foreign 
regulatory  agencies  and  manufactured  in  licensed  and  regulated  facilities.  We  intend  to  secure  additional  limited  product  liability 
insurance coverage for drugs that we commercialize, but may not be able to obtain such insurance on acceptable terms with adequate 

35

coverage,  or  at  reasonable  costs.  Even  if  we  are  ultimately  successful  in  product  liability  litigation,  the  litigation  would  consume 
substantial amounts of our financial and managerial resources and may create adverse publicity, all of which would impair our ability 
to generate sales of the affected product and our other potential drugs. Moreover, product recalls may be issued at our discretion or at 
the  direction  of  the  FDA  and  foreign  regulatory  agencies,  other  governmental  agencies  or  companies  having  regulatory  control  for 
drug sales. Product recalls are generally expensive and often have an adverse effect on the reputation of the drugs being recalled and 
of the drug’s developer or manufacturer.

We  may  be  required  to  indemnify  third  parties  against  damages  and  other  liabilities  arising  out  of  our  development, 
commercialization and other business activities, which could be costly and time-consuming and distract management. If third parties 
that have agreed to indemnify us against damages and other liabilities arising from their activities do not fulfill their obligations, then 
we may be held responsible for those damages and other liabilities.

Our  relationships  with  customers,  healthcare  providers,  clinical  trial  sites  and  professionals  and  third-party  payors  will  be 
subject to applicable anti-kickback, fraud and abuse and other laws and regulations. If we fail to comply with federal, state and 
foreign  laws  and  regulations,  including  healthcare,  privacy  and  data  security  laws  and  regulations,  we  could  face  criminal 
sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors play a primary role in the recommendation and prescription of any drug 
candidates  for  which  we  may  obtain  marketing  approval.  Our  arrangements  with  customers,  healthcare  providers  and  professionals 
and  third-party  payors  may  expose  us  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and  regulations  that  may 
constrain the business or financial arrangements and relationships through which we develop, and may market, sell and distribute, our 
products  for  which  we  obtain  marketing  approval.  Restrictions  under  applicable  federal  and  state  healthcare  laws  and  regulations, 
include, but are not limited to, the following:

•

•

•

•

•

The  federal  healthcare  anti-kickback  statute  prohibits,  among  other  things,  persons  from  knowingly  and  willfully 
soliciting,  offering,  receiving  or  providing  remuneration,  directly  or  indirectly,  in  cash  or  in  kind,  to  induce  or  reward 
either  the  referral  of  an  individual  for,  or  the  purchase,  order  or  recommendation  of,  any  good  or  service,  for  which 
payment may be made under federally funded healthcare programs such as Medicare and Medicaid. This statute has been 
broadly interpreted to apply to manufacturer arrangements with prescribers, purchasers and formulary managers, among 
others. Several other countries, including the United Kingdom, have enacted similar anti-kickback, fraud and abuse, and 
healthcare laws and regulations.
The federal False Claims Act imposes civil penalties, including civil whistleblower or qui tam actions, against individuals 
or entities for knowingly presenting, or causing to be presented, to the federal government, claims for payment that are 
false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal 
government.  The  government  and  qui  tam  relators  have  brought  False  Claims  Act  actions  against  pharmaceutical 
companies on the theory that their practices have caused false claims to be submitted to the government. There is also a 
separate false claims provision imposing criminal penalties.
The  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  or  HIPAA,  as  amended  by  the  Health 
Information  Technology  for  Economic  and  Clinical  Health  Act,  imposes  criminal  and  civil  liability  for  executing  a 
scheme  to  defraud  any  healthcare  benefit  program.  HIPAA  also  imposes  obligations,  including  mandatory  contractual 
terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information. 
HIPAA also imposes criminal liability for knowingly and willfully falsifying, concealing or covering up a material fact or 
making  any  materially  false  statement  in  connection  with  the  delivery  of  or  payment  for  healthcare  benefits,  items  or 
services.
The federal Physician Payments Sunshine Act requires manufacturers of drugs, devices, biologics and medical supplies to 
report  to  the  HHS  information  related  to  payments  and  other  transfers  of  value  made  to  or  at  the  request  of  covered 
recipients,  such  as  physicians  and  teaching  hospitals,  and  physician  ownership  and  investment  interests  in  such 
manufacturers. Payments made to physicians and research institutions for clinical trials are included within the ambit of 
this law.
Analogous state laws and regulations, such as state anti-kickback and false claims laws, may apply to sales or marketing 
arrangements  and  claims  involving  healthcare  items  or  services  reimbursed  by  non-governmental  third-party  payors, 
including  private  insurers,  and  some  state  laws  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical 
industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government 
in addition to requiring drug manufacturers to report information related to payments to physicians and other health care 
providers or marketing expenditures.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations 
will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply 
with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If 
our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be 
subject  to  significant  civil,  criminal  and  administrative  penalties,  damages,  fines,  exclusion  from  government  funded  healthcare 
programs,  such  as  Medicare  and  Medicaid,  and  the  curtailment  or  restructuring  of  our  operations.  Exclusion,  suspension  and 
debarment  from  government  funded  healthcare  programs  would  significantly  impact  our  ability  to  commercialize,  sell  or  distribute 

36

any drug. If any of the physicians or other providers or entities with whom we expect to do business are found to be not in compliance 
with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded 
healthcare programs.

The  collection,  use,  disclosure,  transfer,  or  other  processing  of  personal  data  regarding  individuals  in  the  European  Union, 
including personal health data, is subject to the EU General Data Protection Regulation (the “GDPR”), which became effective in May 
2018.  The  GDPR,  which  is  wide-ranging  in  scope,  imposes  several  requirements  relating  to  the  control  over  personal  data  by 
individuals to whom the personal data relates, the information provided to the individuals, the documentation we must maintain, the 
security and confidentiality of the personal data, data breach notification and the use of third-party processors in connection with the 
processing of personal data. The GDPR also imposes strict rules on the transfer of personal data out of the European Union, provides 
an enforcement authority and authorizes the imposition of large penalties for noncompliance, including the potential for fines of up to 
€20 million or 4% of the annual global revenues of the non-compliant company, whichever is greater. The GDPR has increased our 
responsibility and potential liability in relation to personal data that we process compared to prior European Union law, and we may 
be required to put in place additional mechanisms to ensure compliance with the GDPR, which could divert management’s attention 
and increase our cost of doing business. However, despite our ongoing efforts to bring our practices into compliance with the GDPR, 
we may not be successful either due to various factors within our control or other factors outside our control. It is also possible that 
local data protection authorities may have different interpretations of the GDPR, leading to potential inconsistencies amongst various 
European  Union  Member  States.  Any  failure  or  alleged  failure  (including  as  a  result  of  deficiencies  in  our  policies,  procedures  or 
measures relating to privacy, data security, marketing or communications) by us to comply with laws, regulations, policies, legal or 
contractual  obligations,  industry  standards  or  regulatory  guidance  relating  to  privacy  or  data  security,  may  result  in  governmental 
investigations  and  enforcement  actions,  litigation,  fines  and  penalties  or  adverse  publicity.  In  addition,  new  regulation,  legislative 
actions  or  changes  in  interpretation  of  existing  laws  or  regulations  regarding  data  privacy  and  security  (together  with  applicable 
industry standards) may increase our costs of doing business. We expect that there will continue to be new proposed laws, regulations 
and industry standards relating to privacy and data protection in the United States, the European Union and other jurisdictions, such as 
the California Consumer Privacy Act of 2018 that will go into effect beginning January 1, 2020, and we cannot determine the impact 
such future laws, regulations and standards will have on our business.

Comprehensive U.S. tax reform legislation could increase the tax burden on our orphan drug programs and adversely affect 
our business and financial condition.

The U.S. government enacted comprehensive tax legislation in 2017 (the “2017 Tax Act”) that includes significant changes to 
the taxation of business entities. These changes include, among others, (i) a permanent reduction to the corporate income tax rate, (ii) 
a  partial  limitation  on  the  deductibility  of  business  interest  expense  and  net  operating  loss  carryforwards,  (iii)  a  shift  of  the  U.S. 
taxation  of  multinational  corporations  from  a  tax  on  worldwide  income  to  a  territorial  system  (along  with  certain  rules  designed  to 
prevent erosion of the U.S. income tax base) and (iv) a one-time tax on accumulated offshore earnings held in cash and illiquid assets, 
with the latter taxed at a lower rate. Further, the comprehensive tax legislation, among other things, reduces the orphan drug tax credit 
from  50%  to  25%  of  qualifying  expenditures.  When  and  if  we  become  profitable,  this  reduction  in  tax  credits  may  result  in  an 
increased federal income tax burden on our orphan drug programs as it may cause us to pay federal income taxes earlier under the 
revised tax law than under the prior law and, despite being partially off-set by a reduction in the corporate tax rate from a top marginal 
rate of 35% to a flat rate of 21%, may increase our total federal tax liability attributable to such programs. 

Notwithstanding the reduction in the corporate income tax rate, the overall impact of this comprehensive tax legislation resulted 
in  an  overall  reduction  in  our  deferred  tax  assets,  and  our  business  and  financial  condition  could  still  be  adversely  affected  as 
additional guidance and regulations are issued with respect to the original tax law change. In addition, it is uncertain if and to what 
extent various states will conform to this comprehensive tax legislation. The impact of this comprehensive tax legislation on holders of 
our common stock is also uncertain and could be adverse. Investors should consult with their legal and tax advisors with respect to this 
comprehensive tax legislation and the potential tax consequences of investing in or holding our common stock.

Our ability to use net operating loss carryforwards and tax credit carryforwards to offset future taxable income may be subject 
to certain limitations, and ownership changes may limit our ability to use our net operating losses and tax credits in the future.

Our ability to use our federal and state net operating loss carryforwards (“NOLs”) to offset potential future taxable income and 
reduce  related  income  taxes  depends  upon  our  generation  of  future  taxable  income.  We  cannot  predict  with  certainty  when,  or 
whether, we will generate sufficient taxable income to use our NOLs. 

Our federal NOLs generated prior to 2018 will continue to be governed by tax rules in effect prior to the 2017 Tax Act, with 
unused NOLs expiring 20 years after we report a tax loss. These NOLs could expire unused and be unavailable to offset future taxable 
income. We cannot predict if and to what extent various states will conform to the 2017 Tax Act.

In  addition,  generally,  if  one  or  more  stockholders  or  groups  of  stockholders  who  owns  at  least  5%  of  stock  increases  its 
ownership by more than 50% over its lowest ownership percentage within a three-year testing period, an ownership change occurs (an 
“Ownership Change”). Our ability to utilize our NOLs and tax credit carryforwards to reduce taxes payable in a year we have taxable 
income may be limited if there has been an Ownership Change in our stock. Similar rules may apply under state tax laws. We may 
experience a Ownership Changes in the future as a result of future stock sales or other changes in the ownership of our stock, some of 
which are beyond our control and, as a result, NOLs generated in 2017 and before, may expire unused. 

37

Any material limitation or expiration of our NOLs and tax credit carryforwards may harm our future net income by effectively 

increasing our future effective tax rate, which could result in a reduction in the market price of our common stock.

Responding to any claims relating to improper handling, storage or disposal of the hazardous chemicals and radioactive and 
biological materials we use in our business could be time-consuming and costly.

Our research and development processes involve the controlled use of hazardous materials, including chemicals and radioactive 
and biological materials. Our operations produce hazardous waste products. We cannot eliminate the risk of accidental contamination 
or discharge and any resultant injury from those materials. Federal, state and local laws and regulations govern the use, manufacture, 
storage, handling and disposal of hazardous materials. We may be sued for any injury or contamination that results from our or third 
parties’ use of these materials. Compliance with environmental laws and regulations is expensive, and current or future environmental 
regulations may impair our research, development and production activities.

Our  facilities  in  California  are  located  near  an  earthquake  fault,  and  an  earthquake  or  other  types  of  natural  disasters, 
catastrophic events or resource shortages could disrupt our operations and adversely affect our results.

All  our  facilities  and  our  important  documents  and  records,  such  as  hard  and  electronic  copies  of  our  laboratory  books  and 
records  for  our  drug  candidates  and  compounds  and  our  electronic  business  records,  are  located  in  our  corporate  headquarters  at  a 
single location in South San Francisco, California near active earthquake zones. If a natural disaster, such as an earthquake, fire or 
flood,  a  catastrophic  event  such  as  a  disease  pandemic  or  terrorist  attack,  or  a  localized  extended  outage  of  critical  utilities  or 
transportation systems occurs, we could experience a significant business interruption. Our partners and other third parties on which 
we  rely  may  also  be  subject  to  business  interruptions  from  such  events.  In  addition,  California  from  time  to  time  has  experienced 
shortages of water, electric power and natural gas. Future shortages and conservation measures could disrupt our operations and cause 
expense, thus adversely affecting our business and financial results.

Risks Related to an Investment in Our Common Stock

We expect that our stock price will fluctuate significantly, and you may not be able to resell your shares at or at or above your 
investment price.

The stock market, particularly in recent years, has experienced significant volatility, particularly with respect to pharmaceutical, 
biotechnology  and  other  life  sciences  company  stocks,  which  often  does  not  relate  to  the  operating  performance  of  the  companies 
represented by the stock. Factors that could cause volatility in the market price of our common stock include, but are not limited to:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

announcements concerning any of the clinical trials for our drug candidates (including, but not limited to, the timing of 
initiation or completion of such trials and the results of such trials, and delays or discontinuations of such trials, including 
delays resulting from slower than expected or suspended patient enrollment or discontinuations resulting from a failure to 
meet pre-defined clinical end points);

announcements concerning our strategic alliance with Amgen or Astellas or future strategic alliances;

failure or delays in entering additional drug candidates into clinical trials;

failure or discontinuation of any of our research programs;

issuance of new or changed securities analysts’ reports or recommendations;

failure or delay in establishing new strategic alliances, or the terms of those alliances;

market conditions in the pharmaceutical, biotechnology and other healthcare-related sectors;

actual or anticipated fluctuations in our quarterly financial and operating results;

developments or disputes concerning our intellectual property or other proprietary rights;

introduction of technological innovations or new products by us or our competitors;

issues in manufacturing, packaging, labeling and distribution of our drug candidates or drugs;

market acceptance of our drugs;

third-party healthcare coverage and reimbursement policies;

FDA or other U.S. or foreign regulatory actions affecting us or our industry;

litigation or public concern about the safety of our drug candidates or drugs;

additions or departures of key personnel;

substantial sales of our common stock by our existing stockholders, whether or not related to our performance;

automated trading activity by algorithmic and high-frequency trading programs; and

volatility in the stock prices of other companies in our industry or in the stock market generally.

38

These and other external factors may cause the market price and demand for our common stock to fluctuate substantially, which 
may limit or prevent investors from readily selling their shares of common stock and may otherwise negatively affect the liquidity of 
our common stock. In addition, when the market price of a stock has been volatile, holders of that stock have instituted securities class 
action  litigation  against  the  company  that  issued  the  stock.  If  any  of  our  stockholders  brought  a  lawsuit  against  us,  we  could incur 
substantial costs defending the lawsuit. Such a lawsuit could also divert our management’s time and attention.

If  securities  or  industry  analysts  publish  inaccurate  or  unfavorable  research  about  our  business,  our  stock  price  and  trading 
volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish 
about us or our business. If one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable 
research about our business, our stock price may decline. If one or more of these analysts ceases coverage of our company or fails to 
publish  reports  on  us  regularly,  demand  for  our  stock  could  decrease,  which  might  cause  our  stock  price  and  trading  volume  to 
decline.  

In addition, as required by the new revenue recognition standards under ASC 606, we disclose the aggregate unsatisfied amount 
of  transaction  price  allocated  to  performance  obligations  as  of  the  end  of  the  reporting  period.  Market  practices  surrounding  the 
calculation  of  this  measure  are  still  evolving.  It  is  possible  that  analysts  and  investors  could  misinterpret  our  disclosure  or  that  the 
terms  of  our  research  or  license  agreements  or  other  circumstances  could  cause  our  methods  for  preparing  this  disclosure  to  differ 
significantly from others, which could lead to inaccurate or unfavorable forecasts by analysts and investors.

Regardless  of  accuracy,  unfavorable  interpretations  of  our  financial  information  and  other  public  disclosures  could  have  a 
negative impact on our stock price. If our financial performance fails to meet analyst estimates, for any of the reasons discussed above 
or otherwise, or one or more of the analysts who cover us downgrade our common stock or change their opinion of our common stock, 
our stock price would likely decline.

If  the  ownership  of  our  common  stock  continues  to  be  highly  concentrated,  it  may  prevent  you  and  other  stockholders  from 
influencing significant corporate decisions and may result in conflicts of interest that could cause our stock price to decline.

Our executive officers, directors and their affiliates beneficially own or control some of the outstanding shares of our common 
stock. Accordingly, these executive officers, directors and their affiliates, acting as a group, may have substantial influence over the 
outcome of corporate actions requiring stockholder approval, including the election of directors, any merger, consolidation or sale of 
all or substantially all our assets or any other significant corporate transactions. These stockholders may also delay or prevent a change 
of  control  of  us,  even  if  such  a  change  of  control  would  benefit  our  other  stockholders.  The  significant  concentration  of  stock 
ownership may adversely affect the trading price of our common stock due to investors’ perception that conflicts of interest may exist 
or arise.

Volatility in the stock prices of other companies may contribute to volatility in our stock price.

The  stock  market  in  general,  and  the  Nasdaq  stock  exchanges  and  the  market  for  technology  companies  in  particular,  have 
experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the operating performance 
of those companies. Further, there has been particular volatility in the market prices of securities of early stage and clinical stage life 
sciences companies. These broad market and industry factors may seriously harm the market price of our common stock, regardless of 
our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class 
action litigation has often been instituted. A securities class action suit against us could result in substantial costs, potential liabilities 
and the diversion of management’s attention and resources, and could harm our reputation and business.

Our common stock is thinly traded and there may not be an active, liquid trading market for our common stock.

There is no guarantee that an active trading market for our common stock will be maintained on Nasdaq, or that the volume of 
trading will be sufficient to allow for timely trades. Investors may not be able to sell their shares quickly or at the latest market price if 
trading in our stock is not active or if trading volume is limited. In addition, if trading volume in our common stock is limited, trades 
of relatively small numbers of shares may have a disproportionate effect on the market price of our common stock.

Our  stockholders  will  experience  substantial  additional  dilution  if  outstanding  equity  awards  are  exercised  or  settled  for 
common stock.

The  exercise  of  stock  options  or  settlement  of  equity  awards  for  common  stock  would  be  substantially  dilutive  to  the 
outstanding shares of common stock. Any dilution or potential dilution may cause our stockholders to sell their shares, which would 
contribute to a downward movement in the market price of our common stock.

Evolving  regulation  of  corporate  governance  and  public  disclosure  may  result  in  additional  expenses,  use  of  resources  and 
continuing uncertainty.

We  regularly  evaluate  and  monitor  developments  with  respect  to  new  and  proposed  laws,  regulations  and  standards.  For 
example, we spend significant financial and human resources to document and test the adequacy of our internal control over financial 
reporting to comply with the internal control requirements the Sarbanes-Oxley Act. 

39

We  intend  to  maintain  high  standards  of  corporate  governance  and  public  disclosure  and  to  invest  the  resources  necessary  to 
comply with evolving laws, regulations and standards. This investment may result in increased general and administrative expenses 
and a diversion of management time and attention from revenue-generating activities to compliance activities.

Changing laws, regulations and standards relating to corporate governance and public disclosure create uncertainty for public 
companies.  In  many  cases,  changes  lack  specificity  and  compliance  with  these  changes  may  evolve  over  time  as  new  guidance  is 
provided by regulatory and governing bodies. We cannot accurately predict or estimate the amount or timing of the additional effort or 
expense we may incur complying with changes in these laws, regulations and standards. Therefore, we can provide no assurance as to 
conclusions of management or by our independent registered public accounting firm with respect to the effectiveness of our internal

Management’s Discussion and Analysis of Financial Condition and Results of Operations

This  discussion  and  analysis  should  be  read  in  conjunction  with  our  financial  statements  and  accompanying  notes  included 

elsewhere in this report. Operating results are not necessarily indicative of results that may occur in future periods.

Overview

We are a late-stage biopharmaceutical company focused on discovering, developing and commercializing first-in-class muscle 
activators  and  best-in-class  muscle  inhibitors  as  potential  treatments  for  debilitating  diseases  in  which  muscle  performance  is 
compromised  and/or  declining.  We  have  discovered  and  are  developing  muscle-directed  investigational  medicines  that  may 
potentially improve the healthspan of people with devastating cardiovascular and neuromuscular diseases of impaired muscle function. 
Our research and development activities relating to the biology of muscle function have evolved from our knowledge and expertise 
regarding the cytoskeleton, a complex biological infrastructure that plays a fundamental role within every human cell. As a leader in 
muscle biology and the mechanics of muscle performance, we are developing small molecule drug candidates specifically engineered 
to impact muscle function and contractility. 

Our drug candidates currently in clinical development are: omecamtiv mecarbil, a novel cardiac myosin activator which we are 
developing for the potential treatment of heart failure, reldesemtiv, a novel fast skeletal muscle troponin activator (“FSTA”) which we 
are  developing  for  the  potential  treatment  of  amyotrophic  lateral  sclerosis  (“ALS”)  and  spinal  muscular  atrophy  (“SMA”),  CK-
3773274  (“CK-274”),  a  novel  cardiac  myosin  inhibitor,  which  we  are  developing  for  the  potential  treatment  of  hypertrophic 
cardiomyopathy (“HCM”) and AMG 594, a novel cardiac troponin activator which is the subject of a Phase 1 clinical study.

Omecamtiv  mecarbil  is  being  evaluated  for  the  potential  treatment  of  heart  failure  under  a  strategic  alliance  with  Amgen 
established in 2006 to discover, develop, and commercialize novel small molecule therapeutics designed to activate cardiac muscle 
contractility  pursuant  to  the  collaboration  and  option  agreement  dated  December  29,  2006,  as  amended  (the  “Amgen  Agreement”). 
Amgen, in collaboration with Cytokinetics, is conducting GALACTIC-HF (Global Approach to Lowering Adverse Cardiac Outcomes 
Through Improving Contractility in Heart Failure), a Phase 3 cardiovascular outcomes clinical trial of omecamtiv mecarbil in heart 
failure. In collaboration with Amgen, we are conducting METEORIC-HF (Multicenter Exercise Tolerance Evaluation of Omecamtiv 
Mecarbil  Related  to  Increased  Contractility  in  Heart  Failure),  a  second  Phase  3  clinical  trial  intended  to  evaluate  its  potential  to 
increase exercise performance.

Reldesemtiv  selectively  activates  the  fast  skeletal  muscle  troponin  complex  in  the  sarcomere  by  increasing  its  sensitivity  to 
calcium,  leading  to  an  increase  in  skeletal  muscle  contractility.  Cytokinetics  and  Astellas  are  developing  reldesemtiv  under  the 
Amended  and  Restated  License  and  Collaboration  Agreement  dated  December  22,  2014,  as  amended  (the  “Astellas  Agreement”). 
Astellas  holds  an  exclusive  license  to  develop  and  commercialize  reldesemtiv  worldwide,  subject  to  our  development  and 
commercialization participation rights. In collaboration with Astellas, we conducted a Phase 2 clinical trial of reldesemtiv in patients 
with SMA and we are conducting a Phase 2 clinical trial of reldesemtiv in patients with ALS, called FORTITUDE-ALS (Functional 
Outcomes  in  a  Randomized  Trial  of  Investigational  Treatment  with  CK-2127107  to  Understand  Decline  in  Endpoints  –  in  ALS). 
Astellas,  in  collaboration  with  us,  conducted  a  Phase  2  clinical  trial  of  reldesemtiv  in  patients  with  chronic  obstructive  pulmonary 
disease (“COPD”) and a Phase 1b clinical trial of reldesemtiv in elderly subjects with limited mobility. 

CK-274 is a novel, oral, small molecule cardiac myosin inhibitor that we discovered independent of our collaborations. CK-274 
arose  from  an  extensive  chemical  optimization  program  conducted  with  careful  attention  to  therapeutic  index  and  pharmacokinetic 
properties that may translate into best-in-class potential in clinical development. CK-274 was designed to reduce the hypercontractility 
that is associated with HCM. In preclinical models, CK-274 reduces myocardial contractility by binding directly to cardiac myosin at 
a distinct and selective allosteric binding site, thereby preventing myosin from entering a force producing state. CK-274 reduces the 
number  of  active  actin-myosin  cross  bridges  during  each  cardiac  cycle  and  consequently  reduces  myocardial  contractility.  This 

42

mechanism of action may be therapeutically effective in conditions characterized by excessive hypercontractility, such as HCM. We 
are conducting a Phase 1 double-blind, randomized, placebo-controlled, multi-part, single and multiple ascending dose clinical trial of 
CK-274 in healthy adult subjects.

AMG  594  was  discovered  under  our  joint  research  program  with  Amgen.  In  collaboration  with  Cytokinetics,  Amgen  is 
conducting a randomized, placebo-controlled, double-blind, single and multiple ascending dose, single-center Phase 1 study to assess 
the safety, tolerability, pharmacokinetics and pharmacodynamics of AMG 594 in healthy subjects.

Our research continues to drive innovation and leadership in muscle biology, evidenced by three new muscle biology directed 
compounds advancing from research to development in 2018. All of our drug candidates have arisen from our cytoskeletal research 
activities.  Our  focus  on  the  biology  of  the  cytoskeleton  distinguishes  us  from  other  biopharmaceutical  companies,  and  potentially 
positions us to discover and develop novel therapeutics that may be useful for the treatment of severe diseases and medical conditions. 
Each of our drug candidates has a novel mechanism of action compared to currently marketed drugs, which we believe validates our 
focus on the cytoskeleton as a productive area for drug discovery and development. We intend to leverage our experience in muscle 
contractility to expand our current pipeline and expect to identify additional potential drug candidates that may be suitable for clinical 
development. 

Critical Accounting Polices and Significant Estimates

Our  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  are  based  on  our  financial  statements,  which 
have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United States.  The  preparation  of  these 
financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses 
and  related  disclosure  of  contingent  assets  and  liabilities.  We  review  our  estimates  on  an  ongoing  basis.  We  base  our  estimates  on 
historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results may 
differ from these estimates under different assumptions or conditions. While our significant accounting policies are described in more 
detail  in  the  notes  to  our  financial  statements  included  in  this  Annual  Report  on  Form 10-K,  we  believe  the  following  accounting 
policies to be critical to the judgments and estimates used in the preparation of our financial statements.

Revenue Recognition

On  January  1,  2018,  we  adopted  Accounting  Standards  Codification  606,  Revenue  from  Contracts  with  Customers  (“ASC 
606”),  using  the  modified  retrospective  method.  On  January  1,  2018,  for  contracts  within  the  scope  of  ASC  606,  we  recognized  a 
contract asset or liability and reduced our accumulated deficit for the effect of adopting ASC 606 and did not revise our prior period 
financial statements. Pursuant to ASC 606, to recognize revenue from a contract with a customer, we:

(i) identify our contracts with our customers;
(ii) identify our distinct performance obligations in each contract;
(iii) determine the transaction price of each contract;
(iv) allocate the transaction price to the performance obligations; and
(v) recognize revenue as we satisfy our performance obligations.

At contract inception, we assess the goods or services promised within each contract and assess whether each promised good or 
service is distinct and determine those that are performance obligations. We then recognize as revenue the amount of the transaction 
price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Collaborative Arrangements

We enter into collaborative arrangements with partners that typically include payment to us for one of more of the following: (i) 
license fees; (ii) milestone payments related to the achievement of developmental, regulatory, or commercial goals; and (iii) royalties 
on net sales of licensed products. Each of these payments results in collaboration or other revenues. Where a portion of non-refundable 
up-front  fees  or  other  payments  received  are  allocated  to  continuing  performance  obligations  under  the  terms  of  a  collaborative 
arrangement, they are recorded as deferred revenue and recognized as revenue when (or as) the underlying performance obligation is 
satisfied.

As  part  of  the  accounting  for  these  arrangements,  we  must  develop  estimates  and  assumptions  that  require  judgment  to 
determine  the  underlying  stand-alone  selling  price  for  each  performance  obligation  which  determines  how  the  transaction  price  is 
allocated  among  the  performance  obligation.  The  stand-alone  selling  price  may  include  such  items  as,  forecasted  revenues, 
development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success, 
to determine the transaction price to allocate to each performance obligation.

For  our  collaboration  agreements  that  include  more  than  one  performance  obligation,  such  as  a  license  combined  with  a 
commitment  to  perform  research  and  development  services,  we  make  judgments  to  assess  the  nature  of  the  combined  performance 
obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the 
appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. We evaluate our 
progress each reporting period and, if necessary, adjust the measure of a performance obligation and related revenue recognition.

43

License  Fees:  If  a  license  to  our  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations 
identified in the arrangement, we recognize revenues from non-refundable, up-front fees allocated to the license when the license is 
transferred  to  the  licensee  and  the  licensee  is  able  to  use  and  benefit  from  the  license.  For  licenses  that  are  bundled  with  other 
promises,  we  utilize  judgment  to  assess  the  nature  of  the  combined  performance  obligation  to  determine  whether  the  combined 
performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for 
purposes  of  recognizing  revenue  from  non-refundable,  up-front  license  fees.  We  evaluate  the  measure  of  progress  each  reporting 
period and, if necessary, adjust the measure of performance and related revenue recognition.

Milestone Payments: We use judgement to determine whether a milestone is considered probable of being reached. Using the 
most likely amount method, we include the value of a milestone payment in the consideration for a contract at inception if we then 
conclude  achieving  the  milestone  is  more  likely  than  not.  Otherwise,  we  exclude  the  value  of  a  milestone  payment  from  contract 
consideration at inception and recognize revenue for a milestone at a later date, when we judge that it is more likely than not that the 
milestone will be achieved. If we conclude it is probable that a significant revenue reversal would not occur, the associated milestone 
is  included  in  the  transaction  price.  We  then  allocate  the  transaction  price  to  each  performance  obligation  on  a  relative  stand-alone 
selling price basis, for which we recognize revenue as or when the performance obligations under the contract are satisfied. At the end 
of each subsequent reporting period, we re-evaluate the probability of achievement of such milestones and any related constraint, and 
if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, 
which would affect license, collaboration and other revenues and earnings in the period of adjustment. 

Royalties: For contracts that include sales-based royalties, we recognize revenue at the later of (i) when the related sales occur, 
or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied. To date, we have not 
recognized any royalty revenues resulting from contracts. 

Research  and  Development  Cost  Reimbursements:  Our  Astellas  and  Amgen  arrangements  include  promises  of  research  and 
development  services.  We  have  determined  that  these  services  collectively  are  distinct  from  the  licenses  provided  to  Astellas  and 
Amgen and as such, these promises are accounted for as a separate performance obligation recorded over time. We record revenue for 
these services as the performance obligations are satisfied, which we estimate using internal development costs incurred.

Accrued Research and Development Expenditures

A substantial portion of our preclinical studies and all of our clinical trials have been performed by third-party CROs and other 
vendors  and  our  accruals  for  expenses  for  preclinical  studies  and  clinical  trials  may  be  significant.  For  preclinical  studies,  the 
significant factors used in estimating accruals include the percentage of work completed to date and contract milestones achieved. For 
clinical  trial  expenses,  the  significant  factors  used  in  estimating  accruals  include  the  number  of  patients  enrolled,  duration  of 
enrollment, milestones achieved and percentage of work completed to date. We monitor patient enrollment levels and related activities 
to the extent practicable through internal reviews, correspondence and status meetings with CROs, and review of contractual terms. 
We depend on the timeliness and accuracy of data provided by its CROs and other vendors to accrue expenses. If we receive and rely 
on  incomplete  or  inaccurate  data,  accruals  and  expenses  may  be  too  high  or  too  low  at  a  given  point  in  time  and  corresponding 
adjustments to accruals and expenses would be made in future periods when the actual expense becomes known.

 Liability Related to Sale of Future Royalties

We  treat  the  Liability  related  to  sale  of  future  royalties  as  a  debt  financing,  to  be  amortized  under  the  effective  interest  rate 

method over the life of the related royalty stream.

The Liability related to sale of future royalties and the debt amortization are based on our current estimates of future royalties 
expected to be paid over the life of the arrangement. We will periodically assess the expected royalty payments using a combination of 
internal projections and forecasts from external sources. To the extent our future estimates of future royalty payments are greater or 
less than its previous estimates or the estimated timing of such payments is materially different than its previous estimates, we will 
adjust the Liability related to sale of future royalties and prospectively recognize related non-cash interest expense.

 Results of Operations

Revenues

Our  revenues  since  inception  were  primarily  from  our  strategic  alliances  and  grants  revenues.  Under  our  agreements  with 
Amgen and Astellas, we received payments including upfront license fees, reimbursements of internal costs of certain FTEs and costs 
to  support  research  and  development  programs,  and  milestone  payments.  We  have  not  generated  any  revenue  from  commercial 
product sales to date.

We  may  also  be  entitled  to  additional  milestone  payments  and  other  contingent  payments  upon  the  occurrence  of  specific 

events. We expect that our revenue will continue to fluctuate in future periods.

Our  revenues  in  2018  and  2017  were  primarily  from  our  strategic  alliances  with  Astellas  and  Amgen.  Research  and 
development revenues from Astellas were $24.4 million in 2018, including $22.4 million for reimbursements and $2.0 million in a 
milestone payment for initiation of IND-enabling studies for CK-601. Research and development revenues from Astellas were $11.9 
million in 2017 for reimbursements. Research and development revenues from Amgen were $1.9 million in 2018 for reimbursements 
and $12.3 million in 2017, consisting of $1.3 for reimbursements and $11.0 million in milestone payments. Research and development 
revenues from Amgen in 2017 was offset by $20.0 million for our payments to Amgen to co-fund the Phase 3 development program 
of  omecamtiv  mecarbil  in  exchange  for  an  increased  royalty  upon  potential  commercialization.  Research  and  development  revenue 
included $0.2 million in 2018 for a milestone payment received under our agreement with MyoKardia, Inc. and $0.4 million in 2017 
in grant revenue.

License revenue from Astellas was $5.1 million in 2018 and $8.8 million in 2017 and consisted of recognition of license fees for 
development of reldesemtiv. License revenue decreased in 2018 from 2017 primarily because of adopting ASC 606, Revenue from 
Contracts with Customers. 

Research and development expenses

We incur research and development expenses associated with both partnered and our own research activities. 

Research and development expenses related to any development we elect to fund consist primarily of employee compensation, 

supplies and materials, costs for consultants and contract research and manufacturing, facilities costs and depreciation of equipment.

Research and development expenses decreased to $89.1 million in 2018 from $90.3 million in 2017. Research and development 

expenses by program for 2018 and 2017 were:

Research  and  development  expenses  decreased  in  2018  compared  to  2017  primarily  due  to  suspending  development  of 
tirasemtiv  in  late  2017,  offset  in  part  by  increased  clinical  development  of  reldesemtiv  and  omecamtiv  mecarbil  and  development 
activities for CK-274.

Under our strategic alliance with Astellas, we expect to continue developing reldesemtiv to treat ALS and SMA, as well as CK-
601,  potentially  to  treat  other  diseases  and  medical  conditions  associated  with  muscle  weakness  or  wasting.  Under  our  strategic 
alliance  with  Amgen,  we  expect  to  continue  the  Phase  3  development  of  omecamtiv  mecarbil  for  the  potential  treatment  of  heart 
failure. We expect to continue the development of CK-274 to assess the potential of CK-274 to improve exercise capacity and relieve 
symptoms in patients with hyperdynamic ventricular contraction due to HCM. 

Clinical development timelines, the likelihood of success and total completion costs vary significantly for each drug candidate 
and are difficult to estimate. We anticipate that we will determine on an ongoing basis which research and development programs to 
pursue and how much funding to direct to each program, taking into account the scientific and clinical success of each drug candidate. 
The lengthy process of seeking regulatory approvals and subsequent compliance with applicable regulations requires the expenditure 
of  substantial  resources.  Any  failure  by  us  to  obtain  and  maintain,  or  any  delay  in  obtaining,  regulatory  approvals  could  cause  our 
research and development expenditures to increase and, in turn, could have a material adverse effect on our results of operations.

General and administrative expenses

General and administrative expenses consist primarily of compensation for employees in executive and administrative functions, 
including,  but  not  limited  to,  finance,  human  resources,  legal,  business  and  commercial  development  and  strategic  planning.  Other 
significant  costs  include  facilities  costs,  consulting  costs  and  professional  fees  for  accounting  and  legal  services,  including  legal 
services associated with obtaining and maintaining patents and regulatory compliance. 

General  and  administrative  expenses  decreased  to  $31.3  million  in  2018  from  $36.5  million  in  2017,  primarily  due  to  lower 

commercial readiness activities after suspending development of tirasemtiv in late 2017.

We  expect  that  general  and  administrative  expenses  will  fluctuate  in  the  future,  depending  in  part  on  the  timing  of  and 

investments in commercial readiness.

Interest expense

Interest expense in 2018 and 2017 consisted primarily of interest expense related to the Loan and Security Agreement, dated as 
of October 19, 2015 and amended on October 27, 2017 by and among the Company, Oxford Finance LLC and Silicon Valley Bank, as 
amended (the “Loan Agreement”). Interest expense increased in 2018 compared to 2017 primarily due to higher average loan balances 
outstanding in 2018 compared to 2017 as well as due to increases in prevailing interest rates. 

Non-cash interest expense on Liability related to sale of future royalties

Non-cash interest expense related to Liability related to sale of future royalties in 2018 and 2017 results from accretion of the 
liability related to sale of future royalties. We anticipate that this non-cash interest expense will increase in the future primarily due to 
increased accretion over time.

Interest and Other Income, net

Interest  and  other  income,  net  for  2018  and  2017  consisted  primarily  of  interest  income  generated  from  our  cash,  cash 

equivalents and investments. Other income consisted of net gains on upon disposal of equipment.

Liquidity and Capital Resources

At December 31, 2018, our cash, cash equivalents and short-term investments totaled $198.7 million.

Sources and Uses of Cash

We  have  funded  our  operations  and  capital  expenditures  with  proceeds  primarily  from  private  and  public  sales  of  our  equity 
securities, a royalty monetization agreement, strategic alliances, long-term debt, other financings, interest on investments and grants. 
We  have  generated  significant  operating  losses  since  our  inception.  Our  expenditures  are  primarily  related  to  research  and 
development activities. 

Net cash used in operating activities was $101.2 million for 2018 and was largely due to our net loss for 2018, offset by non-
cash  expenses  included  in  net  loss,  as  well  as  cash  used  to  fund  the  Co-Invest  Option  for  omecamtiv  mecarbil.  Net  cash  used  in 
operating activities was $101.8 million for 2017 and was largely due to our net loss of $127.8 million less non-cash charges such as 
stock-based  compensation  expense  and  non-cash  interest  expense  on  liability  related  to  sale  of  future  royalties  of  $9.0  million  and 
$14.0 million, respectively.

Net  cash  provided  in  investing  activities  of  $5.1  million  in  2018  was  primarily  due  to  maturities  of  investments  of  $246.2 
million, offset in part by purchases of investments of $240.2 million and property and equipment of $0.9 million. Net cash used in 
investing  activities  of  $65.8 million  in  2017  was  primarily  due  to  purchases  of  investments  of  $240.4  million  and  property  and 
equipment of $2.9 million, partially offset by maturities of investments of $177.5 million.

Net cash provided by financing activities of $13.1 million in 2018 was primarily due to proceeds from additional long-term debt 
of $10.0 million and net proceeds from issuance of our Common Stock. Net cash provided by financing activities was $225.9 million 
in  2017  was  primarily  due  to  net  proceeds  from  issuance  of  our  Common  Stock  and  from  the  liability  related  to  sales  of  future 
royalties.

In  November  2017,  we  entered  into  a  Controlled  Equity  OfferingSM  Sales  Agreement  (the  “ATM  Facility”)  with  Cantor 
Fitzgerald & Co. (“Cantor”) for the sale, in our sole discretion, of shares of our common stock, having an aggregate offering price of 
up to $75.0 million through Cantor, as our sales agent. As of December 31, 2018, we had not sold any shares of common stock under 
the ATM Facility.

In March 2019, we terminated the ATM Facility and entered into a new sales agreement (the “New ATM Facility”) with Cantor, 
which provides for the sale, in our sole discretion, of shares of our common stock having an aggregate offering price of up to $35.0 
million through Cantor, as our sales agent. The issuance and sale of these shares by us pursuant to the New ATM Facility are deemed 
“at the market” offerings and are registered under the Securities Act of 1933, as amended. We will pay a commission of up to 3.0% of 
gross sales proceeds of any common stock sold under the New ATM Facility.

In future periods, we expect to incur substantial costs as we continue to expand our research programs and related research and 
development  activities.  We  expect  to  incur  significant  research  and  development  expenses  as  we  advance  the  research  and 
development of compounds from our other muscle biology programs through research to candidate selection to clinical development.

the expansion and advancement of our research programs;

the hiring of additional employees and consultants;

the expansion of our facilities;

the acquisition of technologies, products and other business opportunities that require financial commitments; and

our revenues, if any, from successful development of our drug candidates and commercialization of potential drugs.

We  have  incurred  an  accumulated  deficit  of  $743.3  million  since  inception  and  there  can  be  no  assurance  that  we  will  attain 
profitability.  We  are  subject  to  risks  common  to  clinical-stage  companies  including,  but  not  limited  to, development  of  new  drug 
candidates, dependence on key personnel, and the ability to obtain additional capital as needed to fund our future plans. Our liquidity 
will  be  impaired  if  sufficient  additional  capital  is  not  available  on  terms  acceptable  to  us,  if  at  all.  Until  we  achieve  profitable 
operations,  we  intend  to  continue  to  fund  operations  through  payments  from  strategic  collaborations,  additional  sales  of  equity 
securities, grants and other financings. We have never generated revenues from commercial sales of our drugs and may not have drugs 
to market for at least several years, if ever. Our success is dependent on our ability to obtain additional capital by entering into new 
strategic  collaborations  and/or  through  financings,  and  ultimately  on  our  and  our  collaborators’  ability  to  successfully  develop  and 
market one or more of our drug candidates. We cannot be certain that sufficient funds will be available from such collaborators or 
financings  when  needed  or  on  satisfactory  terms.  Additionally,  there  can  be  no  assurance  that  any  of  drugs  based  on  our  drug 
candidates will be accepted in the marketplace or that any future products can be developed or manufactured at an acceptable cost. 
These factors could have a material adverse effect on our future financial results, financial position and cash flows.

Based on the current status of our development plans, we believe that our existing cash and cash equivalents, investments and 
interest earned on investments will be sufficient to meet our projected operating requirements for at least the next 12 months. If, at any 
time, our prospects for internally financing our research and development programs decline, we may decide to reduce research and 
development expenses by delaying, discontinuing or reducing our funding of development of one or more of our drug candidates or of 
other  research  and  development  programs.  Alternatively,  we  might  raise  funds  through  strategic  relationships,  public  or  private 
financings or other arrangements. There can be no assurance that funding, if needed, will be available on attractive terms, or at all, or 
in  accordance  with  our  planned  timelines.  Furthermore,  financing  obtained  through  future  strategic  relationships  may  require  us  to 
forego certain commercialization and other rights to our drug candidates. Similarly, any additional equity financing may be dilutive to 
stockholders and debt financing, if available, may involve restrictive covenants. Our failure to raise capital as and when needed could 
have a negative impact on our financial condition and our ability to pursue our business strategy.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders
Cytokinetics, Incorporated

Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheet of Cytokinetics, Incorporated (the “Company”) as of December 31, 
2018, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for the year then 
ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated 
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018, and the 
results of its operations and its cash flows for the year then ended, in conformity with US generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal 
Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 
Framework) and our report dated March 6, 2019 expressed an adverse opinion thereon.

Adoption of ASU No. 2014-09 
As discussed in Note 1 to the consolidated financial statements, the Company changed its method for recognizing revenue as a result 
of the adoption of Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), using the 
modified retrospective method effective January 1, 2018.

Basis for Opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the 
Company’s financial statements based on our audit. We are a public accounting firm registered with the PCAOB and are required to 
be independent with respect to the Company in accordance with the US federal securities laws and the applicable rules and regulations 
of the Securities and Exchange Commission and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. 
Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error 
or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence 
regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used 
and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe 
that our audit provides a reasonable basis for our opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — Organization and Accounting Policies

Organization

Cytokinetics,  Incorporated  (the  “Company”,  “we”  or  “our”)  was  incorporated  under  the  laws  of  the  state  of  Delaware  on 
August 5, 1997. We are a late-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.

Our  financial  statements  contemplate  the  conduct  of  our  operations  in  the  normal  course  of  business.  We  have  incurred  an 
accumulated deficit of $743.3 million since inception and there can be no assurance that we will attain profitability. We had a net loss 
of $106.3 million and net cash used in operations of $101.2 million for the year ended December 31, 2018. Cash, cash equivalents and 
investments increased to $198.7 million at December 31, 2018 from $285.4 million at December 31, 2017. We anticipate that we will 
have operating losses and net cash outflows in future periods.

We are subject to risks common to late-stage biopharmaceutical companies including, but not limited to, development of new 
drug  candidates,  dependence  on  key  personnel,  and  the  ability  to  obtain  additional  capital  as  needed  to  fund  our  future  plans. Our 
liquidity will be impaired if sufficient additional capital is not available on terms acceptable to us. We have funded our operations and 
capital expenditures with proceeds primarily from private and public sales of our equity securities, a royalty monetization agreement, 
strategic  alliances,  long-term  debt,  other  financings,  interest  on  investments  and  grants.  Until  we  achieve  profitable  operations,  we 
intend to continue to fund operations through payments from strategic collaborations, additional sales of equity securities, grants and 
debt financings. We have never generated revenues from commercial sales of our drugs and may not have drugs to market for at least 
several years, if ever. Our success is dependent on our ability to enter into new strategic collaborations and/or raise additional capital 
and to successfully develop and market one or more of our drug candidates. As a result, we may choose to raise additional capital 
through equity or debt financings to continue to fund our operations in the future. We cannot be certain that sufficient funds will be 
available  from  such  a  financing  or  through  a  collaborator  when  required  or  on  satisfactory  terms.  Additionally,  there  can  be  no 
assurance that our drug candidates will be accepted in the marketplace or that any future products can be developed or manufactured 
at an acceptable cost. These factors could have a material adverse effect on our future financial results, financial position and cash 
flows.

Based  on  the  current  status  of  our  research  and  development  plans,  we  believe  that  our  existing  cash,  cash  equivalents  and 
investments  will  be  sufficient  to  fund  our  cash  requirements  for  at  least  the  next  12 months  after  the  issuance  of  the  consolidated 
financial statements. If, at any time, our prospects for financing our research and development programs decline, we may decide to 
reduce  research  and  development  expenses  by  delaying,  discontinuing  or  reducing  our  funding  of  one  or  more  of  our  research  or 
development  programs.  Alternatively,  we  might  raise  funds  through  strategic  collaborations,  public  or  private  financings  or  other 
arrangements. Such funding, if needed, may not be available on favorable terms, or at all. The financial statements do not include any 
adjustments that might result from the outcome of this uncertainty.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires 
management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent 
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting 
period. Actual results could differ from those estimates.

Basis of Presentation

The consolidated financial statements include the accounts of Cytokinetics Incorporated and its wholly owned subsidiary and 
have been prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”). Intercompany transactions and 
balances have been eliminated in consolidation.

Concentration of Credit Risk and Other Risks and Uncertainties

Financial  instruments  that  potentially  subject  us  to  concentrations  of  risk  consist  principally  of  cash  and  cash  equivalents, 

investments, long-term debt and accounts receivable.

Our  cash,  cash  equivalents  and  investments  are  invested  in  deposits  with  two  major  financial  institutions  in  the  United 

States. Deposits in these banks may exceed the amount of insurance provided on such deposits. 

Our exposure to credit risk associated with non-payment is limited to our strategic partners Amgen Inc. (“Amgen”) and Astellas 
Pharma  Inc.  (“Astellas”)  and  any  material  non-payment  from  our  partners  would  result  in  a  material  breach  of  the  agreements 
underlying our strategic partnerships.

Drug candidates we develop may require approvals or clearances from the U.S. Food and Drug Administration (“FDA”) or other 
regulatory  agencies  prior  to  commercial  sales.  There  can  be  no  assurance  that  our  drug  candidates  will  receive  any  of  the  required 
approvals or clearances. If we were to be denied approval, or clearance or any such approval or clearance was to be delayed, it would 
have a material adverse impact on us.

Cash and Cash Equivalents

We consider all highly liquid investments with a maturity of three months or less at the time of purchase to be cash equivalents.

Investments

Available-for-sale  investments.      Our  investments  consist  of  U.S. Treasury  securities,  agency  bonds,  commercial  paper, 
corporate  debt  and  money  market  funds.  We  designate  all  investments  as  available-for-sale  and  report  them  at  fair  value,  based on 
quoted marked prices, with unrealized gains and losses recorded in accumulated other comprehensive loss. The cost of securities sold 
is based on the specific-identification method. Investments with original maturities greater than three months and remaining maturities 
of one year or less are classified as short-term investments. Investments with remaining maturities greater than one year are classified 
as long-term investments. The amortized cost of debt securities in this category is adjusted for amortization of premiums and accretion 
of discounts to maturity. Such amortization is included in interest income. Recognized gains and losses and declines in value judged to 
be  other-than-temporary,  if  any,  on  available-for-sale  securities  are  included  in  other  income  or  expense.  Interest  and  dividends  on 
securities classified as available-for-sale are included in Interest and other, net.

Other-than-temporary impairment.     All of our available-for-sale investments are subject to a periodic impairment review. We 
recognize  an  impairment  charge  when  a  decline  in  the  fair  value  of  investments  below  the  cost  basis  is  judged  to  be  other-than-
temporary.  Factors  we  consider  in  assessing  whether  an  other-than-temporary  impairment  has  occurred  include:  the  nature  of  the 
investment;  whether  the  decline  in  fair  value  is  attributable  to  specific  adverse  conditions  affecting  the  investment;  the  financial 
condition  of  the  investee;  the  severity  and  the  duration  of  the  impairment;  and  whether  we  have  the  intent  and  ability  to  hold  the 
investment to maturity. When we determine that an other-than-temporary impairment has occurred, the investment is written down to 
its market value at the end of the period in which it is determined that an other-than-temporary decline has occurred.

Property and Equipment, net

Property  and  equipment  are  stated  at  cost  less  accumulated  depreciation  and  are  depreciated  on  a  straight-line  basis  over  the 
estimated  useful  lives  of  the  related  assets,  which  are  generally  three  years  for  computer  equipment  and  software,  five  years  for 
laboratory  equipment  and  office  equipment,  and  seven  years  for  furniture  and  fixtures.  Amortization  of  leasehold  improvements  is 
computed using the straight-line method over the shorter of the remaining lease term or the estimated useful life of the related assets, 
typically  ranging  from  three  to  seven  years.  Upon  sale  or  retirement  of  assets,  the  costs  and  related  accumulated  depreciation  and 
amortization are removed from the balance sheet and the resulting gain or loss is reflected in operations. 

Impairment of Long-lived Assets

We  review  long-lived  assets,  including  property  and  equipment,  for  impairment  whenever  events  or  changes  in  business 
circumstances indicate that the carrying amount of the assets may not be fully recoverable. Impairment is measured as the amount by 
which  the  carrying  amount  of  a  long-lived  asset  exceeds  its  fair  value.  We  would  recognize  an  impairment  loss  when  estimated 
undiscounted  future  cash  flows  expected  to  result  from  the  use  of  the  asset  and  its  eventual  disposition  are  materially  less  than  its 
carrying amount. 

Revenue Recognition

On  January  1,  2018,  we  adopted  Accounting  Standards  Codification  606,  Revenue  from  Contracts  with  Customers  (“ASC 
606”),  using  the  modified  retrospective  method.  On  January  1,  2018,  for  contracts  within  the  scope  of  ASC  606,  we  recognized  a 
contract asset or liability and reduced our accumulated deficit for the effect of adopting ASC 606 and did not revise our prior period 
financial statements. Pursuant to ASC 606, to recognize revenue from a contract with a customer, we:

(i) identify our contracts with our customers;
(ii) identify our distinct performance obligations in each contract;
(iii) determine the transaction price of each contract;
(iv) allocate the transaction price to the performance obligations; and
(v) recognize revenue as we satisfy our performance obligations.

At contract inception, we assess the goods or services promised within each contract and assess whether each promised good or 
service is distinct and determine those that are performance obligations. We then recognize as revenue the amount of the transaction 
price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Collaborative Arrangements

57

CYTOKINETICS, INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

We enter into collaborative arrangements with partners that typically include payment to us for one of more of the following: (i) 
license fees; (ii) milestone payments related to the achievement of developmental, regulatory, or commercial goals; and (iii) royalties 
on net sales of licensed products. Each of these payments results in collaboration or other revenues. Where a portion of non-refundable 
up-front  fees  or  other  payments  received  are  allocated  to  continuing  performance  obligations  under  the  terms  of  a  collaborative 
arrangement, they are recorded as deferred revenue and recognized as revenue when (or as) the underlying performance obligation is 
satisfied.

As  part  of  the  accounting  for  these  arrangements,  we  must  develop  estimates  and  assumptions  that  require  judgment  to 
determine  the  underlying  stand-alone  selling  price  for  each  performance  obligation  which  determines  how  the  transaction  price  is 
allocated  among  the  performance  obligation.  The  stand-alone  selling  price  may  include  such  items  as,  forecasted  revenues, 
development timelines, reimbursement rates for personnel costs, discount rates and probabilities of technical and regulatory success, 
to determine the transaction price to allocate to each performance obligation.

For  our  collaboration  agreements  that  include  more  than  one  performance  obligation,  such  as  a  license  combined  with  a 
commitment  to  perform  research  and  development  services,  we  make  judgments  to  assess  the  nature  of  the  combined  performance 
obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the 
appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. We evaluate our 
progress each reporting period and, if necessary, adjust the measure of a performance obligation and related revenue recognition.

License  Fees:  If  a  license  to  our  intellectual  property  is  determined  to  be  distinct  from  the  other  performance  obligations 
identified in the arrangement, we recognize revenues from non-refundable, up-front fees allocated to the license when the license is 
transferred  to  the  licensee  and  the  licensee  is  able  to  use  and  benefit  from  the  license.  For  licenses  that  are  bundled  with  other 
promises,  we  utilize  judgment  to  assess  the  nature  of  the  combined  performance  obligation  to  determine  whether  the  combined 
performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for 
purposes  of  recognizing  revenue  from  non-refundable,  up-front  license  fees.  We  evaluate  the  measure  of  progress  each  reporting 
period and, if necessary, adjust the measure of performance and related revenue recognition.

Milestone Payments: We use judgement to determine whether a milestone is considered probable of being reached. Using the 
most likely amount method, we include the value of a milestone payment in the consideration for a contract at inception if we then 
conclude  achieving  the  milestone  is  more  likely  than  not.  Otherwise,  we  exclude  the  value  of  a  milestone  payment  from  contract 
consideration at inception and recognize revenue for a milestone at a later date, when we judge that it is more likely than not that the 
milestone will be achieved. If we conclude it is probable that a significant revenue reversal would not occur, the associated milestone 
is  included  in  the  transaction  price.  We  then  allocate  the  transaction  price  to  each  performance  obligation  on  a  relative  stand-alone 
selling price basis, for which we recognize revenue as or when the performance obligations under the contract are satisfied. At the end 
of each subsequent reporting period, we re-evaluate the probability of achievement of such milestones and any related constraint, and 
if necessary, adjust our estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, 
which would affect license, collaboration and other revenues and earnings in the period of adjustment. 

Royalties: For contracts that include sales-based royalties, we recognize revenue at the later of (i) when the related sales occur, 
or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied. To date, we have not 
recognized any royalty revenues resulting from contracts. 

Research  and  Development  Cost  Reimbursements:  Our  Astellas  and  Amgen  arrangements  include  promises  of  research  and 
development  services.  We  have  determined  that  these  services  collectively  are  distinct  from  the  licenses  provided  to  Astellas  and 
Amgen and as such, these promises are accounted for as a separate performance obligation recorded over time. We record revenue for 
these services as the performance obligations are satisfied, which we estimate using internal development costs incurred.

Accrued Research and Development Expenditures 

A substantial portion of our preclinical studies and all of our clinical trials have been performed by third-party contract research 
organizations (“CROs”) and other vendors and our accruals for expenses for preclinical studies and clinical trials may be significant. 
For  preclinical  studies,  the  significant  factors  used  in  estimating  accruals  include  the  percentage  of  work  completed  to  date  and 
contract  milestones  achieved.  For  clinical  trial  expenses,  the  significant  factors  used  in  estimating  accruals  include  the  number  of 
patients  enrolled,  duration  of  enrollment,  milestones  achieved  and  percentage  of  work  completed  to  date.  We  monitor  patient 
enrollment  levels  and  related  activities  to  the  extent  practicable  through  internal  reviews,  correspondence  and  status  meetings  with 
CROs, and review of contractual terms. We depend on the timeliness and accuracy of data provided by its CROs and other vendors to 
accrue expenses. If we receive and rely on incomplete or inaccurate data, accruals and expenses may be too high or too low at a given 
point  in  time  and  corresponding  adjustments  to  accruals  and  expenses  would  be  made  in  future  periods  when  the  actual  expense 
becomes known.

Research and Development Expenditures

Research and development costs are charged to operations as incurred. Research and development expenses consist primarily of 
clinical manufacturing costs, preclinical study expenses, consulting and other third-party costs, employee compensation, supplies and 
materials, allocation of overhead and occupancy costs, facilities costs and depreciation of equipment.

Income Taxes

We  account  for  income  taxes  under  the  asset  and  liability  method.  Under  this  method,  deferred  tax  assets  and  liabilities  are 
determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in 
effect  for  the  year  in  which  the  differences  are  expected  to  affect  taxable  income.  Valuation  allowances  are  established  when 
necessary to reduce deferred tax assets to the amounts expected to be realized.

We recognize uncertain tax positions taken or expected to be taken on a tax return. Tax positions are initially recognized when it 
is more likely than not that the position will be sustained upon examination by the tax authorities. Such tax positions are initially and 
subsequently measured as the largest amount of tax benefit that is more likely than not of being realized upon ultimate settlement with 
the tax authority assuming full knowledge of the position and relevant facts.

We recognize interest accrued related to unrecognized tax benefits and penalties as income tax expense.

Stock-Based Compensation

We maintain equity incentive plans under which incentive stock options may be granted to employees and nonqualified stock 
options,  restricted  stock  awards,  restricted  stock  units  and  stock  appreciation  rights  may  be  granted  to  employees,  directors, 
consultants and advisors. In addition, we maintain an employee stock purchase plan (“ESPP”) under which employees may purchase 
shares of our common stock through payroll deductions.

Stock-based compensation expense related to stock options granted to employees and directors is recognized based on the grant 
date estimated fair values, net of an estimated forfeiture rate, using the Black Scholes option pricing model. The value of the portion 
of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service period. We estimate our 
forfeiture rate based on an analysis of our actual forfeitures and the experience of other companies in the same industry, and we will 
continue  to  evaluate  the  adequacy  of  the  forfeiture  rate  assumption  based  on  actual  forfeitures,  analysis  of  employee  turnover  and 
other related factors.

Stock-based compensation expense related to restricted stock units granted to employees is recognized based on the grant-date 

fair value of each award and recorded as expense over the vesting period using the straight-line method, net of estimated forfeitures.

Stock-based compensation expense related to the ESPP is recognized based on the fair value of each award estimated on the first 
day of the offering period using the Black Scholes option pricing model and recorded as expense over the service period using the 
straight-line method.

Amortization of Debt Discount and Issuance Costs 

Debt discount and issuance costs, consisting of legal and other fees directly related to the debt, are offset against gross proceeds 
from  the  issuance  of  debt  and  are  amortized  to  interest  expense  over  the  estimated  life  of  the  debt  based  on  the  effective  interest 
method.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Liability Related to Sale of Future Royalties

We  treat  the  Liability  related  to  sale  of  future  royalties  as  a  debt  financing,  to  be  amortized  under  the  effective  interest  rate 

method over the life of the related royalty stream.

The Liability related to sale of future royalties and the debt amortization are based on our current estimates of future royalties 
expected to be paid over the life of the arrangement. We will periodically assess the expected royalty payments using a combination of 
internal projections and forecasts from external sources. To the extent our future estimates of future royalty payments are greater or 
less than its previous estimates or the estimated timing of such payments is materially different than its previous estimates, we will 
adjust the Liability related to sale of future royalties and prospectively recognize related non-cash interest expense.

Recent Accounting Pronouncements

In  June  2016,  the  FASB  issued  ASU  2016-13,  ‘Financial  Instruments  —  Credit  Losses  —  Measurement  of  Credit  Losses  on 
Financial  Instruments.  ASU 2016-13  changes  the  impairment  model  for  most  financial  assets  and  certain  other  instruments.  ASU 
2016-13 is effective for annual and interim reporting periods beginning after December 15, 2019.  We are in the process of evaluating 
the impact the adoption of this standard would have on our financial statements and disclosures.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). ASU 2016-02 requires management to record right-to-
use asset and lease liability on the statement of financial position for operating leases. ASU 2016-02 is effective for annual and interim 
reporting periods beginning on or after December 15, 2018 and modified retrospective approach is required. We are in the process of 
evaluating the impact the adoption of this standard will have on its financial statements and disclosures and believe that adoption will 
be material to our balance sheet as a result of the recognition of a right-to-use asset and corresponding liability for our building leases 
but will not have a material impact on our results of operations.

In  November  2018,  the  Financial  Accounting  Standards  Board  (“FASB”)  issued  ASU  2018-18,  Collaborative  Arrangements 
(Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 (“ASU 2018-18”), which make targeted improvements to 
clarify the interaction between Topic 808, Collaborative Arrangements, and Topic 606, Revenue from Contracts with Customers. ASU 
2018-18 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption 
is permitted. We are currently evaluating the impact of adopting ASU 2018-18. 

Note 2 — Net Loss Per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of vested common shares outstanding 
during the period. Diluted net (loss) income per share is computed by giving effect to all potentially dilutive common shares, including 
outstanding  stock  options,  unvested  restricted  stock,  warrants,  convertible  preferred  stock  and  shares  issuable  under  our  Employee 
Stock Purchase Plan (“ESPP”), by applying the treasury stock method.

The following instruments were excluded from the computation of diluted net loss per share for the periods presented because 

their effect would have been antidilutive (in thousands):

Options to purchase common stock
Warrants to purchase common stock
Restricted and Performance stock units
Shares issuable related to the ESPP

Note 3 – Revenue Recognition

We believe recognizing revenue as research and development services are performed provides a faithful depiction of the transfer 
of the services because completion of clinical programs results in data useful to determine satisfaction of our promise. We may fund 
research and development in advance of the performance of the services. When we complete our performance obligation, if we have 
received  more  than  we  incurred,  we  are  obligated  to  return  unused  advance  funding.  We  recognize  these  advance  payments  as 
deferred  revenue  until  we  perform  the  related  services.  As  discussed  in  Note  1,  prior  period  amounts  continue  to  be  reported  in 
accordance with our historic accounting under previous revenue recognition guidance, ASC 605.

Note 5 — Fair Value Measurements

We value our financial assets and liabilities at fair value, defined as the price that would be received for assets when sold or paid 
to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data 
or assumptions that we believe market participants would use in pricing the asset or liability, including assumptions about risk and the 
risks  inherent  in  the  inputs  to  the  valuation  technique.  These  inputs  can  be  readily  observable,  market  corroborated  or  generally 
unobservable.

We  primarily  apply  the  market  approach  for  recurring  fair  value  measurements  and  endeavors  to  utilize  the  best  information 
reasonably available. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of 
unobservable inputs to the extent possible and considers the security issuers’ and the third-party insurers’ credit risk in its assessment 
of fair value.

We classify the determined fair value based on the observability of those inputs. Fair value accounting guidance establishes a 
fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted 
prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 
measurement). The three defined levels of the fair value hierarchy are as follows:

Level 1 — Observable inputs, such as quoted prices in active markets for identical assets or liabilities;

Level 2 —  Inputs,  other  than  the  quoted  prices  in  active  markets,  that  are  observable  either  directly  or  through  corroboration 

with observable market data; and

Level 3 —  Unobservable  inputs,  for  which  there  is  little  or  no  market  data  for  the  assets  or  liabilities,  such  as  internally-

developed valuation models.

Investments available for sale at December 31, 2018 excludes an investment in equity classified as a Level 1 investment in our 
short-term investments with a fair value and unrealized gain of $0.7 million. At December 31, 2018, there were no investments that 
had been in a continuous unrealized loss position for 12 months or longer.

The carrying amount of our accounts receivable and accounts payable approximates fair value due to the short-term nature of 

these instruments.

Fair value of financial liabilities:

As of December 31, 2018 and 2017, the fair value of the long-term debt, payable in installments through 2020, approximated its 
carrying value of $42.1 million and $31.8 million, respectively, because it is carried at a market observable interest rate, which is a 
Level 2 input.

As of December 31, 2018, the fair value of the Liability related to the sale of future royalties is based on our current estimates of 
future  royalties  expected  to  be  paid  to  RPI  Finance  Trust  (“RPI”),  an  entity  related  to  Royalty  Pharma,  over  the  life  of  the 
arrangement, which are considered Level 3 inputs (See Note 9 – “Liability Related to Sale of Future Royalties”). 

There were no transfers between Level 1, Level 2, and Level 3 during the periods presented.

Note 7 — Research and Development Arrangements

Amgen Inc. (“Amgen”)

We  and  Amgen  continue  activities  related  to  novel  small  molecule  therapeutics,  including  omecamtiv  mecarbil,  that  activate 
cardiac muscle contractility for potential applications in the treatment of heart failure under our collaboration and option agreement 
with Amgen dated December 29, 2006, as amended (the “Amgen Agreement”). We recognize research and development revenue for 
reimbursements from Amgen of both internal costs of certain FTEs and other costs related to the Amgen Agreement.

Under  the  Amgen  Agreement,  we  are  eligible  to  receive  over  $300.0 million  in  additional  development  milestone  payments 
based on various clinical milestones, including the initiation of certain clinical studies, the submission of an application for marketing 
authorization for a drug candidate to certain regulatory authorities and the receipt of such approvals. Additionally, we are eligible to 
receive  up  to  $300.0 million  in  commercial  milestone  payments  provided  certain  sales  targets  are  met.  Due  to  the  nature  of  drug 
development,  including  the  inherent  risk  of  development  and  approval  of  drug  candidates  by  regulatory  authorities,  we  cannot 
estimate  if  and  when  these  milestone  payments  could  be  achieved  or  become  due  and,  accordingly,  we  consider  the  milestone 
payments to be constrained and exclude the milestone payments from the transaction price. 

We paid Amgen $18.8 million in 2018 and $20.0 million in 2017 and have exercised our option under the Amgen Agreement to 
co-invest $40.0 million in the Phase 3 development program of omecamtiv mecarbil in exchange for a total incremental royalty from 
Amgen of up to 4% on increasing worldwide sales of omecamtiv mecarbil outside Japan (the “Co-Invest Option”). 

Adoption of ASC 606 

We  determined  that  the  Amgen  Agreement  was  within  the  scope  of  ASC  606.  As  of  January  1,  2018,  all  the  performance 
obligations under the Amgen Agreement were complete. On January 1, 2018, we recognized a contract liability for $18.8 million with 
a  corresponding  increase  in  accumulated  deficit  for  the  Co-Invest  Option.  We  paid  Amgen  $18.8  million  for  the  Co-Invest  Option 
during 2018.

Research and development revenues from Amgen for December 31, 2018 and 2017 were as follows (in thousands):

$11.0 million consisted of $10.0 million related to the start in Japan of GALACTIC-HF, the Phase 3 cardiovascular outcomes clinical 
trial  of  omecamtiv  mecarbil  and  $1.0  million  related  to  a  next-generation  cardiac  muscle  activator  that  was  nominated  as  a 
development  candidate  by  the  Joint  Research  Committee.  Accounts  receivable  due  from  Amgen  was  $1.9  million  at  December  31, 
2018 and $1.0 million at December 31, 2017. Prior period amounts continue to be reported in accordance with our historic accounting 
under  previous  revenue  recognition  guidance,  ASC  605.  See  note  3  “Revenue  Recognition”  above,  for  more  information  about  the 
impact of the adoption on ASC 606.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Astellas Pharma Inc. (“Astellas”)

We and Astellas continue activities focused on the research, development, and commercialization of skeletal muscle activators, 
including  reldesemtiv,  as  novel  drug  candidates  for  diseases  and  medical  conditions  associated  with  muscle  weakness  under  the 
Amended and Restated License and Collaboration Agreement dated December 22, 2014, as amended (the “Astellas Agreement”). We 
recognize research and development revenue for reimbursements from Astellas of internal costs of both FTEs and other costs related 
to Astellas Agreement. 

In 2014, we and Astellas amended and restated the license and collaboration agreement (the “2014 Astellas Amendment”) and 
expanded  the  objective  of  the  collaboration  to  include  spinal  muscular  atrophy  (“SMA”)  and  potentially  other  neuromuscular 
indications for reldesemtiv and other fast skeletal muscle troponin activators (“FSTAs”); in connection therewith, Astellas paid us a 
$30.0 million non-refundable upfront license fee and a $15.0 million milestone payment. We determined at that time that the license 
for the expanded SMA rights did not have stand-alone value and the license and research and development services were a single unit 
of accounting and recognized revenue for these payments using the proportional performance model. 

In  2016,  we  and  Astellas  amended  the  Astellas  Agreement  (the  “2016  Astellas  Amendment”)  to  expand  the  collaboration  to 
include the development of reldesemtiv for the potential treatment of amyotrophic lateral sclerosis (“ALS”), as well as the possible 
development  in  ALS  of  other  FSTAs  previously  licensed  by  us  to  Astellas,  and  Astellas  paid  us  a  $35.0  million  non-refundable 
upfront  amendment  fee  and  an  accelerated  $15.0  million  milestone  payment  for  the  initiation  of  the  first  Phase  2  clinical  trial  of 
reldesemtiv  in  ALS  that  was  otherwise  provided  for  in  the  Astellas  Agreement,  as  if  such  milestone  had  been  achieved  upon  the 
execution  of  the  2016  Astellas  Amendment,  and  committed  research  and  development  consideration  of  $44.2  million,  for  total 
consideration  of  $94.2  million.  We  allocated  the  consideration  to  the  license  and  to  the  research  and  development  services,  and 
recognized license revenue and research and development revenue using the proportional performance model.  In addition, Astellas 
paid us a $15.0 million non-refundable million fee for the option for a global collaboration for the development and commercialization 
of tirasemtiv, our first-generation FSTA (the “Option on Tirasemtiv”).

Under  the  Astellas  Agreement,  additional  research  and  early  and  late  state  development  milestone  payments  for  research  and 
clinical milestones, including the initiation of certain clinical studies, the submission of an application for marketing authorization for 
a drug candidate to certain regulatory authorities and the commercial launch of collaboration products could total over $600.0 million 
and  include  up  to  $95.0 million  relating  to  reldesemtiv  in  non-neuromuscular  indications,  and  over  $100.0 million  related  to 
reldesemtiv in each of SMA, ALS and other neuromuscular indications. Additionally, $200.0 million in commercial milestones could 
be  received  under  the  Astellas  Agreement  provided  certain  sales  targets  are  met.  We  are  eligible  to  receive  up  to  $2.0 million  in 
research milestone payments under the collaboration for each future potential drug candidate. Due to the nature of drug development, 
including the inherent risk of development and approval of drug candidates by regulatory authorities, it is not possible to estimate if 
and  when  these  milestone  payments  could  be  achieved  or  become  due,  and  accordingly,  are  constrained  and  not  included  in  the 
transaction price. 

In  collaboration  with  Astellas,  we  are  conducting  a  Phase  2  clinical  trial  of  reldesemtiv  in  patients  with  ALS,  called 
FORTITUDE-ALS  (Functional  Outcomes  in  a  Randomized  Trial  of  Investigational  Treatment  with  CK-2127107  to  Understand 
Decline in Endpoints – in ALS). We and Astellas share equally the costs of developing reldesemtiv in ALS for potential registration 
and marketing authorization in the U.S. and Europe, provided that (i) Astellas has agreed to solely fund Phase 2 development costs of 
reldesemtiv in ALS subject to a right to recoup our share of such costs plus a 100% premium by reducing future milestone and royalty 
payments to us and (ii) we may defer (but not eliminate) a portion of its co-funding obligation for development activities after Phase 2 
for up to 18 months, subject to certain conditions.

Adoption of ASC 606

On January 1, 2018, in adopting ASC 606, we concluded: (i) that the original agreement with Astellas in 2013 was outside the 
scope of ASC 606, since all performance obligations thereunder were completed prior to entering into the 2014 Astellas Amendment 
and the 2014 Astellas Amendment was not an amendment of the original agreement, (ii) the 2014 Astellas Amendment is a separate 
agreement within the scope of ASC 606 with no effect on the ongoing accounting for the related license and research and development 
service deliverables and (iii) the 2016 Astellas Amendment is a separate agreement within the scope of ASC 606. 

In adopting ASC 606 for the 2016 Amendment, we determined:
•

Our performance obligations were the delivery of the license and performance of research and development services;

•

•

•

The transaction price included the $65.0 million in non-refundable fees and $35.6 million in then-committed research and 
development fees;

The consideration allocated to the license resulted in a contract asset of $16.7 million, with a corresponding decrease to 
accumulated deficit on January 1, 2018, and to be realized using the proportional performance model; and

Research services we perform under the Astellas Agreement in 2018 and beyond are a separate contract.

The  transaction  price  above  was  allocated  to  the  license  (approximately  $83  million)  and  to  the  services  (approximately  $18 

million) based on their respective stand-alone prices.

In  2018,  we  completed  all  our  deliverables  for  the  2014  Astellas  Amendment  and  have  recognized  as  revenue  all  the 

consideration under that agreement. We expect to complete all our deliverables for the 2016 Astellas Amendment in 2019. 

We  had  accounts  receivable  from  Astellas  of  $0.3  million  at  December  31,  2018  and  none  at  December  31,  2017.  Deferred 
revenue, current at December 31, 2017 of $9.6 million reflected the unrecognized portion of the license revenue and reimbursements 
and Deferred revenue, non-current at December 31, 2017 of $15.0 million reflected the Option on Tirasemtiv (prior to adopting ASC

2017, we entered into a Second Amendment to Loan and Security Agreement (the “Amended Loan Agreement”) with Oxford and SVB, 
drew  $32.0  million  and  retired  our  then-outstanding  debt  of $30.0  million,  and  $0.5  million related  to the  accrued  portion  of  the  final 
payment fee under the Loan Agreement.  In August 2018, following the satisfaction of certain conditions related to Phase 2 data for 
reldesemtiv  in  SMA  specified  in  the  Loan  Agreement,  we  drew  down  an  additional  $10.0  million  under  the  Amended  Loan 
Agreement and the interest-only period was extended to December 1, 2019.

under the Amended Loan Agreement is the greater of (a) 8.05% or (b) the sum of 6.81% plus the 30-day U.S. LIBOR rate. 

The  Loan  Agreement  contains  customary  representations  and  warranties  and  customary  affirmative  and  negative  covenants 
applicable  to  us  and  includes  customary  events  of  default,  including  but  not  limited  to  the  nonpayment  of  principal  or  interest, 
violations of covenants and material adverse changes. Upon an event of default, the Lenders may, among other things, accelerate the 
loans and foreclose on the collateral. Our obligations under the Amended Loan Agreement are secured by substantially all our current 
and future assets, other than our intellectual property.

Note 9 - Liability Related to Sale of Future Royalties

In February 2017, we and Royalty Pharma Inc. (“RPI”) entered into a Royalty Purchase Agreement (the “Royalty Agreement”), 
under which we sold to RPI for $90.0 million a portion of our right to receive royalties on potential net sales of omecamtiv mecarbil 
(and  potentially  other  compounds  with  the  same  mechanism  of  action)  under  the  Amgen  Agreement  (the  “Royalty  Monetization”). 
The  Royalty  Monetization  is  non-refundable,  even  if  omecamtiv  mecarbil  is  never  commercialized.  We  account  for  the  Royalty 
Monetization  as  a  liability  primarily  because  we  have  significant  continued  involvement  in  generating  the  royalty  stream  under the 
Amgen  Agreement.  Concurrently,  we  entered  into  a  Common  Stock  Purchase  Agreement  with  RPI  through  which  RPI  purchased 
from us 875,656 shares of our common stock for $10.0 million (the “RPI Common Stock”). 

We concluded that there are two units of accounting for the Royalty Monetization and the RPI Common Stock: (1) the Liability 
related to sale of future royalties and (2) the sale of the RPI Common Stock. We determined the fair value for the Liability related to 
sale of future royalties at the time of the Royalty Monetization to be $96.7 million, with an effective annual non-cash interest rate of 
17% based on our estimate of the cash flows to be received over the life of the Royalty Agreement. We determined that the fair value 
of  the  RPI  Common  Stock  was  $8.1  million  at  the  time  we  entered  into  the  Royalty  Agreement.  We  determined  the  fair  value  at 
$131.6 million at December 31, 2017 after considering the new statutory effective tax rate of 21% in 2018.

We allocated the consideration of $100.0 million and related transaction costs of $1.8 million on a relative fair value basis to the 
liability for $92.3 million and the common stock for $7.7 million. Through December 31, 2018, we accreted the Liability related to 
sale of future royalties using the interest method with an annual pre-tax interest rate of 17% and recognized non-cash interest expense 
on liability related to sale of future royalties of $17.8 million in 2018 and $14.0 million in 2017. Transaction costs are amortized to 
interest expense over the estimated term of the Royalty Agreement. Payments made to RPI pursuant to the Royalty Monetization, if 
any, would reduce this liability. 

Note 10 — Commitments and Contingencies

Commitments - Operating Lease

We lease office space under a non-cancelable operating lease that expires in June 2021. The lease provides for rental payments 
on a graduated scale and our payment of certain operating expenses. We recognize rent expense on a straight-line basis over the lease 
period. Rent expense was $5.0 million in 2018, $3.6 million in 2017 and $3.4 million in 2016. 

As  of  December 31,  2018,  future  minimum  lease  payments  under  noncancelable  operating  leases  were  $4.7  million  in  2019, 

$4.8 million in 2020 and $2.5 million in 2021. 

Contingencies

In the ordinary course of business, we may provide indemnifications of varying scope and terms to vendors, lessors, business 
partners  and  other  parties  with  respect  to  certain  matters,  including,  but  not  limited  to,  losses  arising  out  of  our  breach  of  such 
agreements, services to be provided by or on behalf of us, or from intellectual property infringement claims made by third parties. In 
addition, we have indemnification agreements with our directors and certain of our officers and employees that will require us, among 
other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or 
employees. We maintain director and officer insurance, which may cover certain liabilities arising from our obligation to indemnify 
our  directors  and  certain  of  our  officers  and  employees,  and  former  officers  and  directors  in  certain  circumstances.  We  maintain 
product  liability  insurance  and  comprehensive  general  liability  insurance,  which  may  cover  certain  liabilities  arising  from  our 
indemnification obligations. It is not possible to determine the maximum potential amount of exposure under these indemnification 
obligations  due  to  the  limited  history  of  prior  indemnification  claims  and  the  unique  facts  and  circumstances  involved  in  each 
particular  indemnification  obligation.  Such  indemnification  obligations  may  not  be  subject  to  maximum  loss  clauses.  We  are  not 
currently aware of any matters that could have a material adverse effect on our financial position, results of operations or cash flows.

criteria  for  342,500  Performance  Units  were  met,  171,250  of  those  units  vested.    In  March  2018,  the  remaining  171,250  of  these 
Performance Units vested. In 2017, the other 342,500 Performance Units granted in 2015 were forfeited when we determined that the 
performance criteria for those Performance Units would not be met. 

Employee Stock Purchase Plan

Under  our  2015  Employee  Stock  Purchase  Plan  (the  “ESPP”),  employees  may  purchase  common  stock  up  to  a  specified 

maximum amount at a price equal to 85% of the fair market value at certain plan-defined dates.

We issued 144,822 shares at an average price of $6.40 during 2018 and 120,959 shares at an average price of $9.65 in 2017 

pursuant to the ESPP. At December 31, 2018, we have 253,617 shares of common stock reserved for issuance under the ESPP.

Stock-Based Compensation Expense

We use the Black-Scholes option pricing model to determine the fair value of stock option grants to employees and directors and 
employee  stock  purchase  plan  shares.  The  fair  value  of  share-based  payments  was  estimated  on  the  date  of  grant  based  on  the 
following assumptions:

Risk-free interest rate
Volatility
Expected term in years
Expected dividend yield

Year Ended December 31, 2018

We use the U.S. Treasury zero-coupon issues with remaining terms similar to the expected terms of the options for the risk-free 
interest  rate.  We  use  our  own  volatility  history  based  on  its  stock’s  trading  history  and  our  own  historical  exercise  and  forfeiture 
activity  to  estimate  expected  term  for  option  grants.  We  do  not  anticipate  paying  dividends  in  the  foreseeable  future  and  use  an 
expected dividend yield of zero. 

We reviewed the impact of estimating forfeitures on our stock-based compensation, determined the impact was immaterial and 
stopped  estimating  forfeitures  in  2018.  Prior  to  2018,  we  estimated  forfeitures  at  the  time  of  grant  and  revised  those  estimates  in 
subsequent  periods  if  actual  forfeitures  differ  from  our  estimates  using  historical  forfeiture  data  and  recorded  stock-based 
compensation expense on those awards that were expected to vest.

We measure compensation expense for restricted stock units at fair value on the date of grant and recognizes the expense over 
the expected vesting period. We recognize stock-based compensation expense on a straight-line basis over the requisite service period, 
generally  the  vesting  period  of  the  award  for  share-based  awards.  Stock-based  compensation  expense  for  2018  and  2017  was  as

Non-cash  stock-based  compensation  expense  for  share-based  awards  to  non-employees  was  $0.1  million  in  2018  and  $0.5

As of December 31, 2018, we expect to recognize $13.8 million of unrecognized compensation cost related to unvested stock 
options over a weighted-average period of 2.4 years and $3.5 million of unrecognized compensation cost related to unvested restricted 
stock over a weighted-average period of 1.8 years.

Warrants

Pursuant to the Loan Agreement described in Note 8 “Long-Term Debt,” we issued warrants to purchase 65,189 shares of our 
common stock at an exercise price of $6.90 per share and additional warrants to purchase 68,285 shares of our common stock at an 
exercise price of $6.59 per share. In 2017, we issued 16,126 shares of common stock related to cashless exercises of some of these 
warrants. In August 2018, we issued 42,253 warrants with a weighted average of $7.10 per share. At December 31, 2018, 142,359 
warrants with a weighted average exercise price of $6.85 per share were outstanding.

In June 2012, we issued warrants with expiration in June 2017 pursuant to public offerings of our securities in 2012. In 2017, we 

issued 3,450,122 shares of common stock for exercise of these warrants, respectively. 

Controlled Equity Offering

During  2017, we  issued  2,425,625  shares  of  common  stock  under  a  Controlled  Equity  Offering  Sales  Agreement,  an  at-the-

At  December  31,  2018,  federal  NOL  carryforwards  were  $490.1 million  and  apportioned  state  NOL  carryforwards  before 
federal benefits were $252.8 million. If not utilized, federal and state operating loss carryforwards incurred prior to 2018 will begin to 
expire in various amounts beginning 2022 and 2028, respectively. 

At  December  31,  2018,  tax  credits  of  $61.6 million  and  $15.0 million  for  federal  and  state  income  tax  purposes,  respectively 
consisted  of  Research  and  Development  Credits  and  Orphan  Drug  Credits.  If  not  utilized,  the  federal  carryforwards  will  expire  in 
various amounts beginning in 2021. California based credit carryforwards do not expire.

Realization  of  deferred  tax  assets  is  dependent  upon  future  earnings,  if  any,  the  timing  and  amount  of  which  are  uncertain. 
Based  upon  the  weight  of  available  evidence,  which  includes  our  historical  operating  performance,  reported  cumulative  net  losses 
since inception, expected future losses, and difficulty in accurately forecasting our future results and an assessment of both positive 
and negative evidence when determining whether it is more likely than not that deferred tax assets are recoverable, we maintained a 
full valuation allowance on the net deferred tax assets as of December 31, 2018 and 2017. The valuation allowance increased by $16.2 
million in 2018 and decreased by $11.7 million in 2017.

In  general,  under  Section 382  of  the  Internal  Revenue  Code  (“Section  382”),  a  corporation  that  undergoes  an  ‘ownership 
change’  is  subject  to  limitations  on  its  ability  to  utilize  its  pre-change  net  operating  losses  and  tax  credits  to  offset  future  taxable 
income. We do not believe it has experienced an ownership change since 2006 expect a portion of its NOLs and tax credits from prior 
to 2007 will be subject to limitations under Section 382.

result in adjustments to other tax accounts, primarily deferred taxes.

Tax Reform

The Tax Cuts and Jobs Act of 2017 (the “Tax Act”) made significant changes to the Internal Revenue Code. Changes include, 
but are not limited to, a corporate tax rate decrease from 34% to 21% (the “Rate Reduction”) effective for tax years beginning after 
December 31, 2017. We reduced deferred tax assets at December 31, 2017 for the effect of the Rate Reduction. The Rate Reduction 
did not impact our provision for income taxes for 2017 due to the full valuation allowance on deferred tax assets.

Due  to  the  complexities  of  implementing  the  provisions  of  the  Tax  Act,  the  staff  of  the  U.S.  Securities  and  Exchange 
Commission issued Staff Accounting Bulletin 118 (“SAB 118”), which provides guidance on accounting for tax effects of the Tax Act 
and permits a measurement period not to exceed one year from the enactment date for companies to complete the required analyses 
and  accounting.  As  permitted  under  SAB  118,  the  adjustments  we  recorded  due  to  the  Tax  Act,  including  the  remeasurement  of 
deferred tax assets and liabilities and the transition tax, were based on reasonable estimates and were considered provisional during the 
year.  In  the  fourth  quarter  of  2018,  we  completed  our  analysis  to  determine  the  effect  of  the  Tax  Act  and  recorded  immaterial 
adjustments as of December 31, 2018. The Company has considered and completed all applicable elements of tax reform under the 
remeasurement period.

Controls and Procedures

Evaluation of Disclosure Controls and Procedures:

We  maintain  disclosure  controls  and  procedures  that  are  designed  to  ensure  that  information  required  to  be  disclosed  in  our 
reports  under  the  Securities  Exchange  Act  of  1934,  as  amended,  or  the  Exchange  Act,  is  recorded,  processed,  summarized  and 
reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated 
to our management, including our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer, as appropriate, to 
allow  for  timely  decisions  regarding  required  disclosure.  In  designing  and  evaluating  the  disclosure  controls  and  procedures,  we 
recognize  that  any  controls  and  procedures,  no  matter  how  well  designed  and  operated,  can  provide  only  reasonable  assurance  of 
achieving the desired control objectives, and in reaching a reasonable level of assurance, we are required to apply our judgment in 
evaluating the cost-benefit relationship of possible controls and procedures.

As  of  December  31,  2018,  the  end  of  the  period  covered  by  this  report,  we  carried  out  an  evaluation,  including  our  Chief 
Executive  Officer,  Chief  Financial  Officer  and  Chief  Accounting  Officer  of  the  effectiveness  of  the  design  and  operation  of  our 
disclosure  controls  and  procedures.  Based  on  the  foregoing,  our  Chief  Executive  Officer,  Chief  Financial  Officer  and  Chief 
Accounting Officer concluded that our disclosure controls and procedures were not effective as of December 31, 2018.

Management’s Annual Report on Internal Control Over Financial Reporting:

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term 
is  defined  in  Exchange  Act  Rules  13a-15(f)  and  15d-15(f).  Under  the  supervision  and  with  the  participation  of  our  management, 
including  our  Chief  Executive  Officer,  Chief  Financial  Officer  and  Chief  Accounting  Officer,  we  conducted  an  evaluation  of  the 
effectiveness of our internal control over financial reporting as of December 31, 2018 based on the framework in Internal Control — 
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the 
COSO  criteria).  Based  on  the  above  evaluation,  our  management  concluded  that  our  internal  control  over  financial  reporting  was 
ineffective as of December 31, 2018 due to the identification of a material weakness.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is 
a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or 
detected on a timely basis.

As  of  December  31,  2018,  we  identified  a  material  weakness  related  to  the  ineffective  review  and  verification  of  internally 
prepared reports and analyses utilized in the financial closing process. The material weakness is related to employee turnover resulting 
in a temporary lack of resources in financial reporting roles with the appropriate skills to perform effective review during our financial 
statement close process.

This material weakness did not result in the restatement of prior quarterly or annually filed financial statements.

Remediation Plan

To  remediate  the  material  weakness  described  above,  we  are  actively  recruiting  for  open  positions  within  the  accounting 
department and will, as necessary, supplement any interim staffing needs with temporary resources. We will also continue to evaluate 
and improve our internal controls, processes and procedures in the financial statement close process.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders 
Cytokinetics, Incorporated

Opinion on Internal Control over Financial Reporting

We  have  audited  Cytokinetics,  Incorporated’s  internal  control  over  financial  reporting  as  of  December  31,  2018,  based  on  criteria 
established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weakness described below on 
the  achievement  of  the  objectives  of  the  control  criteria,  Cytokinetics,  Incorporated  (the  “Company”)  has  not  maintained  effective 
internal control over financial reporting as of December 31, 2018, based on the COSO criteria.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a 
reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or 
detected  on  a  timely  basis.  The  following  material  weakness  has  been  identified  and  included  in  management’s  assessment. 
Management has identified a material weakness in controls related to the company’s financial statement close process.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States) 
(PCAOB),  the  2018  consolidated  financial  statements  of  the  Company.  This  material  weakness  was  considered  in  determining  the 
nature,  timing  and  extent  of  audit  tests  applied  in  our  audit  of  the  2018  consolidated  financial  statements,  and  this  report  does  not 
affect our report dated March 6, 2019 which expressed an unqualified opinion thereon.

Basis for Opinion 

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of 
the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control 
over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based 
on  our  audit.  We  are  a  public  accounting  firm  registered  with  the  PCAOB  and  are  required  to  be  independent  with  respect  to  the 
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB. 

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit 
to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.  

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness 
exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such 
other  procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audit  provides  a  reasonable  basis  for  our 
opinion. 

Definition and Limitations of Internal Control Over Financial Reporting 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting 
principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures  that  (1)  pertain  to  the 
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the 
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in 
accordance  with  authorizations  of  management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding 
prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect 
on the financial statements. 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections 
of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Other Information

On March 6, 2019, we entered into a Controlled Equity OfferingSM Sales Agreement (the “New ATM Facility”), with Cantor 
Fitzgerald & Co. (“Cantor”), under which we may offer and sell, from time to time at our sole discretion, shares of our common stock, 
par value $0.001 per share, or the Common Stock, having an aggregate offering price of up to $35.0 million through Cantor, as sales 
agent. In connection with the entry into the New ATM Facility, we terminated our prior sales agreement, dated November 3, 2017, 
with Cantor.

Cantor may sell the Common Stock by any method that is deemed to be an “at the market offering” as defined in Rule 415 of 
the Securities Act of 1933, as amended, including sales made directly on the Nasdaq Global Select Market or any other trading market 
for  our  common  stock.  Cantor  will  use  commercially  reasonable  efforts  to  sell  the  Common  Stock  from  time  to  time,  based  upon 
instructions from us (including any price, time or size limits or other customary parameters or conditions we may impose). We will 
pay Cantor a commission of up to 3.0% of the aggregate gross sales proceeds of any common stock sold through Cantor under the 
New ATM Facility, and also have provided Cantor with customary indemnification rights.

We are not obligated to make any sales of Common Stock under the New ATM Facility. The offering of shares of Common 

Stock pursuant to the New ATM Facility will terminate upon the termination of the New ATM Facility in accordance with its terms.

The foregoing description of the New ATM Facility is qualified in its entirety by reference to the New ATM Facility, a copy of
