2014 Annual Report

Delivering on the Potential  
              of Regenerative Medicine

Athersys is an international biotechnology company engaged in the discovery and development of 

therapeutic product candidates designed to extend and enhance the quality of human life. We are developing 
MultiStem® cell therapy, our patented and proprietary, adult-derived stem cell product, initially for disease indications 
in the neurological, cardiovascular, and inflammatory and immune disease areas, and we have several ongoing 
clinical trials evaluating this potential regenerative medicine product. MultiStem cell therapy has shown the ability to 
promote tissue repair and healing in a variety of ways, such as through the production of therapeutic factors produced 
in response to signals of inflammation and tissue damage. Our MultiStem therapy represents a unique “off-the-shelf” 
stem cell product that can be manufactured in a scalable manner, may be stored for years in frozen form and is 
administered without tissue matching or the need for immune suppression. Based upon its efficacy profile, its novel 
mechanisms of action, and a favorable and consistent safety profile demonstrated in both preclinical and clinical 
settings, MultiStem cell therapy could provide a meaningful benefit to patients, including those suffering from serious 
diseases and conditions where the current standard of care is limited or ineffective. 

We have forged a network of strategic alliances and collaborations with leading pharmaceutical and biotechnology 
companies, as well as world-renowned research and clinical institutions in the United States, Europe and Japan to 
further develop our platform and products. More information is available at www.athersys.com.

To My Fellow Shareholders:

Our Company is committed to developing innovative 
therapies for areas where there are serious unmet 
medical needs, reflecting the limitations of current 
standards of care. We believe that by developing safer 
and more effective treatments, we will not only help 
patients and their families by enhancing their recovery 
and quality of life, but we can also create substantial 
value for our shareholders in the process. We are 
committed to developing best-in-class therapies and 
wherever possible, to be first-in-class, as well. Over  
the past year, we have made some exciting progress  
in these pursuits. 

timelines, reduce overall 
development costs and 
accelerate the path to market. 
We are taking advantage of these 
trends through research efforts 
focused in disease areas such 
as stroke and heart attack, with 
high importance in an aging 
population, and through utilizing 
available regulatory pathways  
to accelerate development and  
shorten the time to market. 

Gil Van Bokkelen, Ph.D.
Chairman and Chief Executive Officer

Early on, we recognized that we had the opportunity 
to explore how our proprietary MultiStem® cell therapy 
might be relevant in a wide range of therapeutic areas. 
But, we also understood that in order to efficiently 
identify which areas might represent the best 
development opportunities, we were going to have to 
work collaboratively with others. Over the past decade, 
we have successfully established an international 
network of collaborative relationships and partnerships 
that have helped us identify and explore the potential 
relevance of MultiStem therapy in a number of  
exciting areas. 

International interest in the field of regenerative 
medicine and cell therapy has grown substantially over 
the past few years. With each year, more evidence has 
been generated that suggests these types of therapies 
are poised to fundamentally change and improve 
medical care in many areas. The focus at Athersys has 
been to develop our portfolio of programs in a deliberate 
and methodical manner, and to focus on challenges 
where we feel we can make the biggest difference—by 
effectively addressing major areas of clinical need.

Demographic pressures are escalating, as policymakers 
grasp the dramatic impact to national healthcare 
systems and budgets expected from aging populations. 
There is growing recognition that innovation and novel 
therapies will be key to improving care and reducing 
the burden to government and society. Regulators 
are undertaking initiatives and implementing new 
approaches with the potential to shorten development 

Recognizing that our success will be judged on the 
advancement of our preclinical and clinical programs, 
we believe that we have an attractive pipeline of 
programs and are well-positioned to help patients and 
address unmet needs, thereby creating substantial 
value. Further, we continue to advance these 
opportunities and establish commercial partnerships  
to improve our development trajectory. 

The aging global population 

We believe that in order to become a leading company, 
it pays to consider when and where major market trends 

The elderly segment of the 
population (i.e., individuals over 
the age of 65) in the United States, 
European Union and Japan is 
projected to double in size between 
the years 2010 and 2030, and 
national demographic profiles will be 
changed dramatically.  

2014 Annual Report      1

are occurring, and how our technologies might be 
deployed to address these trends. In the field of 
healthcare and medicine, one of the most important 
trends is the dramatic expansion of the elderly segment 
of the global population.

home care and intensive family support. Through 
technology, we can improve patient quality of life and 
shift the efficiency boundary that enables us to treat 
more patients, and do so more effectively with the 
limited resources available. 

According to economists, this expansion of the global 
elderly population will have a significant effect on 
healthcare systems, quality of life and long-term 
economic prosperity. The elderly segment of the 
population (i.e., individuals over the age of 65) in the 
United States, European Union and Japan is projected 
to double in size between the years 2010 and 2030, 
and national demographic profiles will be changed 
dramatically. In Japan, the problem is particularly 
daunting, as it has the fastest growth rate of the elderly 
population. By the year 2030, individuals over the 
age of 65 in Japan will comprise more than 30% of 
its population, and within roughly two decades, the 
population over the age of 80 will more than double in 
Japan. In the United States, the group over the age of 
65 is projected to grow by more than 80% between the 
years 2010 and 2030, representing an increase from 
40 million individuals to more than 72 million people 
in only two decades. In Europe, this segment of the 
population will swell to more than 125 million people 
by 2030. As the elderly populations in these countries 
and other parts of the world continue to dramatically 
increase in number, it will have an escalating impact 
on healthcare systems around the world. As we age, 
we become much more susceptible to a range of 
diseases and conditions, like heart disease, stroke and 
other conditions. As a result, aggregate demand for 
healthcare resources will continue to rise—creating 
enormous pressures on healthcare systems around the 
world. When coupled with other key trends, such as 
the growing shortage of physicians and nurses, it will 
unavoidably result in rationing and shortages of care…
unless something changes. 

Emerging technologies could help address some 
of these challenges. Through the development of 
novel technologies and approaches like regenerative 
medicine, we hope to be able to overcome existing 
limitations in treatment and care, and dramatically 
improve clinical outcomes. These technologies could 
enable us to enhance patient recovery and well-
being, and potentially lessen the need for extended 
hospitalization, full-time institutional care, professional

Emerging regulatory trends

Governments and policymakers around the world have 
recognized the growing evidence of the potential of 
innovative technologies like regenerative medicine. 
Rather than simply hope that such technology may be 
successfully developed someday, in the past several 
years, regulatory leadership and policymakers have 
taken action to specifically focus on the design and 
implementation of new frameworks that can have a 
dramatic impact on accelerating the development of 
novel treatment approaches that are both safe and 
that can effectively address significant areas of unmet 
medical need.

In the United States, sanctioned by Congress and 
the President, the United States Food and Drug 
Administration has adopted new policies that are 
designed to promote the development of “breakthrough 
therapies” for disease conditions and areas where 
existing care is limited or altogether ineffective. In 
Europe, similar steps have recently been taken, and a 
pilot program has been implemented to promote the 
concept of a “conditional approval” system. 

Perhaps the most exciting recent advance is what has 
occurred in Japan, where an entirely new regulatory 
framework has been implemented that is designed 
specifically for regenerative medicine therapies. This 

We and others are very encouraged by 
the evident safety profile 
and the potential for 
benefit to stroke patients 
treated with MultiStem 
cell therapy within 36 
hours, and what this 
could mean for ischemic 
stroke victims. 

approach, passed by the Japanese government with 
overwhelming support late in 2013, went into effect 
recently. While it’s too early to say just what impact it 
will have, the signs are clear that the overall regulatory 
environment is changing for the better, and the 
emphasis on regenerative medicine technology is 
particularly exciting. 

When the regulatory environment improves, it offers 
up the potential for a shorter, more efficient and more 
cost effective development path. This, in turn, offers up 
the potential for an accelerated path to market and an 
expedited ability to create value for shareholders, while 
also serving the needs of patients that need help. 

Our portfolio of clinical and  
preclinical programs

As the landscape has continued to improve and 
mature, more and more attention is being focused on 
our progress and achievements. Because we are a 
recognized leader in the regenerative medicine field, 
the international investment community, potential 
partners and competitors are tracking our progress 
carefully. With each advance, we better position the 
Company to achieve our ultimate goal, which is to 
successfully develop new products and become a 
market leader.

We are currently focused on advancing key 
therapeutic programs in several areas. These include 
the treatment of neurological disease, cardiovascular 
disease, and inflammatory and immune conditions. 
Most of our programs revolve around the concept of 
treating serious acute conditions that are associated 
with a high degree of morbidity and mortality, 
especially those conditions where current standards  
of care are ineffective or lacking altogether.

In the neurological area, we are intently focused on our 
ongoing international Phase 2 clinical trial evaluating 
the intravenous administration of MultiStem to patients 
that have suffered a debilitating stroke. Extensive 
preclinical work has demonstrated that administration 
of MultiStem provides a durable and robust benefit in 
animal models of acute neurological injury. 

We recently announced initial data from the trial 
demonstrating that MultiStem therapy is safe  
and well-tolerated in these patients and, based on 

post-hoc analyses, appears to provide meaningful 
benefits to patients if treatment occurs within 36 
hours of the stroke. In this post-hoc analyses of the 
patients receiving MultiStem treatment within 36 hours 
compared to placebo patients, there was an increase 
in the proportion of patients achieving an Excellent 
Outcome, independence as measured by a modified 
Rankin Scale (mRS) score of 0-2, an improvement of 
75% or more in the NIH Stroke Scale (NIHSS) score, 
and a Barthel Index score of 95 or 100. We also saw 
reduced mortality and life-threatening serious adverse 
events, lower pulmonary events and infection rates, 
and evidence of a faster time to recovery in patients 
that received treatment with MultiStem. Although 
the study did not meet the primary and secondary 
endpoints that we originally envisioned, we and others 
are very encouraged by the evident safety profile and 
the potential for benefit to stroke patients treated with 
MultiStem cell therapy within 36 hours, and what this 
could mean for ischemic stroke victims.  

In addition to our work in stroke, we have also 
completed substantial work in exploring the potential 
application of MultiStem for traumatic brain injury 
(a leading cause of death and disability among 
young people), acute spinal cord injury, and 
chronic neurological conditions like primary and 
secondary progressive multiple sclerosis. We believe 
that MultiStem cell therapy has the potential to 
meaningfully improve standard of care in multiple 
neurological indications. 

In 2015, we are launching a Phase 2  
clinical trial evaluating treatment of  
patients that have suffered damage from  
the most common type  
of heart attack, and  
the program is being  
supported with $2.8  
million in funding from  
the National Heart  
Lung and Blood Institute, 
part of the National 
Institutes of Health. 

2014 Annual Report      3

In the cardiovascular area, we are exploring the 
application of MultiStem for the treatment of 
significant damage from a heart attack, or acute 
myocardial infarction. In 2015, we are launching a 
Phase 2 clinical trial evaluating treatment of patients 
that have suffered damage from the most common 
type of heart attack, and the program is being 
supported with $2.8 million in funding from the 
National Heart Lung and Blood Institute, part of the 
National Institutes of Health. 

Chugai has a strong history of successful development 
of innovative biological therapies in Japan. We believe 
this sets the stage for what could be a powerful alliance, 
enabling us to achieve important development and 
commercialization goals in Japan that could translate  
to significant value creation for our shareholders.  
Over the year ahead, we expect to explore and evaluate 
other potential development and commercialization 
partnerships that can improve and accelerate  
our programs.

We also continue to advance other programs in the 
inflammatory and immune area. In January 2015, 
we announced that, in collaboration with the Cell 
Therapy Catapult based in London, we were awarded 
a £2 million grant from Innovate U.K. to support a 
clinical trial evaluating MultiStem cell therapy for 
the treatment of acute respiratory distress syndrome 
(ARDS). In the United States, European Union and 
Japan, it is estimated that ARDS affects more than 
450,000 people annually and carries a high rate of 
morbidity and mortality since, currently, there is no 
effective standard of care. We look forward to the 
launch of this trial later this year.  

As our portfolio of clinical and preclinical programs 
continues to mature and expand, we are seeing 
increased interest from potential partners.

Establishing value enhancing  
partnerships

Interest in the regenerative medicine area has  
grown over the past several years. This has 
enabled us to engage in discussions with potential 
development partners, including in Japan where 
interest has increased significantly. In March 2015, 
we were pleased to announce a new partnership 
with Chugai Pharmaceuticals Co. Ltd., focused on 
the development of MultiStem cell therapy for the 
treatment of ischemic stroke in Japan. 

We are excited about this partnership for several 
reasons. First, we believe Chugai will be a good partner. 
Like Athersys, Chugai is committed to developing best-
in-class and first-in-class therapeutics that have the 
potential to address significant areas of unmet medical 
need. Chugai’s leadership places a heavy emphasis on 
helping the patient, and we share core ideals in that 
regard. Second, Chugai has established one of the 
leading hospital products sales forces in Japan. Third,

Over the past few years, we have worked extremely 
hard to achieve key goals and advance our programs. 
Our progress reflects an extraordinary commitment of 
everyone that is part of our organization, and I would 
like to thank all of our employees and collaborators 
for their tenacity and hard work. It also reflects the 
continued faith and support of our shareholders, and 
on behalf of everyone at Athersys, I would also like to 
thank you for your continued support.

ITEM 1.

BUSINESS. 

We are an international biotechnology company that is focused primarily in the field of regenerative medicine. We are committed to the 
discovery and development of best-in-class therapies designed to extend and enhance the quality of human life. We have established a 
portfolio of therapeutic product development programs to address significant unmet medical needs in multiple disease areas. Our 
MultiStem® cell therapy, a patented and proprietary allogeneic stem cell product, is our lead platform product and has been evaluated in 
two completed Phase 1 clinical trials and is currently being evaluated in Phase 2 clinical trials, as well as an investigator-led Phase 1 trial, 
and plans are underway for a Phase 2/3 registration clinical trial. Our current clinical development programs are focused on treating 
neurological conditions, cardiovascular disease, inflammatory and immune disorders, and other conditions where the current standard of 
care is limited or inadequate for many patients. We are also applying our pharmaceutical discovery capabilities to identify and develop 
small molecule compounds with potential applications in indications such as obesity, related metabolic conditions and certain 
neurological conditions. These represent major areas of clinical need, as well as substantial commercial opportunities.  

We believe our MultiStem therapy represents a potential breakthrough in the field of regenerative medicine and stem cell therapy and 
could be used to treat a range of disease indications. MultiStem treatment enhances tissue repair and healing in multiple ways, including 
reducing inflammatory damage, protecting tissue that is at risk following acute or ischemic injury, and promoting formation of new blood 
vessels in regions of ischemic injury. These cells appear to be responsive to the environment in which they are administered, by homing to 
sites of injury and providing active disease response, while producing proteins that may provide benefit in both acute and chronic 
conditions. In contrast to traditional pharmaceutical products or biologics that generally act through a single biological mechanism of 
action, MultiStem cell therapy may enhance healing and tissue repair through multiple distinct mechanisms acting in parallel, such as by 
producing a range of therapeutic factors and dynamically responding to the needs of the body, resulting in a more effective therapeutic 
response.  

The MultiStem product is unique among regenerative medicine approaches because it can be manufactured on a large scale, may be 
administered in an “off-the-shelf” manner with minimal processing, and can augment healing in multiple ways, providing biological 
potency and therapeutic effects that other cell therapy approaches may not be able to achieve. Additionally, MultiStem treatment has 
demonstrated a consistent safety profile in both preclinical and clinical studies. Like drugs and biologics, the product is cleared from the 
body over time, enhancing product safety relative to other types of stem cell therapy. While the product does not permanently engraft in 
the patient, the therapeutic effects of treatment with MultiStem cells appear to have durability.  

We believe the therapeutic and commercial potential for MultiStem cell therapy to be very broad, applying to many areas of significant 
unmet medical need. We are pursuing opportunities in several potential multi-billion dollar markets. While traditional pharmaceuticals 
and biologic therapies typically may be used to treat only a single disease or a narrowly defined set of related conditions, MultiStem cell 
therapy appears to have far broader potential and could be developed in different formulations and with different delivery approaches to 
effectively treat a range of disease indications.  

We have evaluated the use of MultiStem cell therapy as a potential treatment in several disease areas. Working with an international 
network of leading investigators and prominent research and clinical institutions, and through our own internal efforts, we explored the 
potential for MultiStem therapy to be used as a treatment of acute and chronic forms of neurological conditions, cardiovascular disease, 
inflammatory and immune disorders, certain pulmonary conditions and other areas of unmet medical need. At present, we have five 
MultiStem clinical stage programs and plans to add a sixth in 2015. Each of these programs targets an area of significant medical need 
and represents major commercial market opportunities.  

In the neurological area, we are evaluating the potential for MultiStem treatment of patients who have suffered neurological damage from 
an ischemic stroke. This is a double blind, randomized and placebo controlled study evaluating the administration of MultiStem cell 
therapy to patients 24 to 48 hours following the occurrence of a serious stroke. If effective, this would represent a substantial increase in 
the time window for treatment, which currently is limited to several hours. In February 2015, we established a collaboration with Chugai 
Pharmaceutical Co., Ltd., or Chugai, to develop and commercialize MultiStem for the treatment of ischemic stroke in Japan. Chugai will 
be responsible for the development and commercialization of MultiStem for ischemic stroke in Japan on an exclusive basis, and we will 
have the primary responsibility for the manufacture of product for both clinical and commercial purposes.  

We are also in the process of initiating a Phase 2 clinical study for the administration of MultiStem cell therapy to patients that have 
suffered an acute myocardial infarction, or AMI. In 2013, we were awarded a grant from the National Institutes of Health for up to $2.8 
million to support funding this clinical program. Previously we completed a Phase 1 clinical trial involving administration of MultiStem 
cell therapy to patients that have suffered an AMI, and the results of this trial demonstrated consistent safety and encouraging evidence of 
therapeutic benefit among patients with severely compromised heart function. We are completing preparations for the launch of this 
study, which we anticipate will commence on the second quarter of 2015.  

3

Additionally, we evaluated in a completed Phase 1 clinical study the potential for MultiStem cell therapy to prevent or reduce graft-
versus-host disease, or GvHD, and other complications, and to provide supportive care to patients undergoing a hematopoietic stem 
cell transplant to treat leukemia or related conditions. We are preparing to advance our GvHD program into the next phase of clinical 
development and have had several interactions with the United States Food and Drug Administration, or FDA, and similar 
international agencies regarding study design and the potential to accelerate the path to product approval. Initiation of this trial will 
depend on the progress in other clinical trials and the achievement of certain business development and financial objectives. Our 
MultiStem therapy for GvHD has been designated an orphan drug by both the FDA and the European Medicines Agency, or EMA, 
which may provide market exclusivity and other substantial potential incentives and benefits.  

We are also engaged in the preparation stages for clinical studies in other targeted areas, including the treatment of acute respiratory 
distress syndrome, or ARDS. ARDS is a serious immunological and inflammatory condition characterized by widespread 
inflammation in the lungs. Currently, there are limited interventions and no effective drug treatments for ARDS, making it an area of 
high unmet clinical need with high treatment costs. Given the high treatment costs of ARDS, a successful cell therapy could be 
expected to generate significant savings for the healthcare system by reducing days on a ventilator, days in the intensive care unit and 
total days in the hospital, and importantly, could reduce mortality and improve quality of life for those suffering from the 
condition. The medical need for a safe and effective treatment of ARDS is significant due to its high mortality rate, and it affects 
annually approximately 400,000 to 500,000 patients in Europe, the United States and Japan, together. In 2015, we were awarded a 
grant from Innovate UK, formerly the Technology Strategy Board, of up to approximately £2.0 million in support of a Phase 2a 
clinical study evaluating the administration of MultiStem cell therapy to ARDS patients. The study will be conducted with the 
assistance of the Cell Therapy Catapult, or Catapult, and we anticipate that the trial will commence in the second half of 2015.  

MultiStem cell therapy is also being evaluated in other ongoing clinical trials. Our collaborative partner, Pfizer Inc., or Pfizer, is 
completing a Phase 2 clinical study exploring administration of MultiStem to patients with ulcerative colitis, or UC, a common form 
of inflammatory bowel disease, or IBD. Preliminary results were announced in the spring of 2014. Finally, a research collaborator and 
leading transplantation center in Europe is conducting a small, exploratory institutional-sponsored Phase 1 study to evaluate the 
administration of MultiStem cell therapy to patients undergoing a liver transplant. Previously published work involving preclinical 
models of organ transplantation demonstrated that administration of MultiStem cell therapy can help induce immune tolerance to 
organ allografts, and eliminated the need for long-term immune suppression.  

Our development approach has historically involved establishing collaborative relationships with leading research and clinical centers 
in the United States and internationally. This has enabled us to methodically advance multiple programs in areas of defined unmet 
medical need in a resource efficient manner. Furthermore, by emphasizing the potential application of our technologies in areas of 
significant clinical need, we believe we are well positioned to utilize recent regulatory initiatives that are designed to promote the 
rapid and cost effective development of innovative new therapies. These include recent initiatives in the United States being 
implemented by the FDA involving the broadened application of the accelerated approval pathway, and the new Breakthrough 
Therapies framework, as well as the new accelerated Regenerative Medicine regulatory framework in Japan that is designed to enable 
rapid conditional authorization of qualified regenerative medicine therapies. We believe such initiatives could accelerate the 
development and commercialization of products like MultiStem cell therapy, if clinical results demonstrate appropriate safety and 
therapeutic effectiveness, thereby increasing shareholder value.  

In addition to our MultiStem programs, we have applied our pharmaceutical discovery capabilities to identify and develop novel 
pharmaceuticals to treat obesity, related metabolic conditions such as diabetes, and certain neurological indications such as 
schizophrenia. Our 5HT2c agonist program for obesity works by the same mechanism as Lorcaserin®, which was approved by the 
FDA in 2012 for the treatment of obesity. We believe our compounds have the potential to provide superior weight loss, while also 
achieving a superior safety and tolerability profile. In addition, we demonstrated that our compounds are complementary with other 
agents that have been approved by the FDA for treating obesity. Furthermore, we evaluated certain compounds in preclinical models 
of schizophrenia that exhibit an attractive selectivity profile and also observed that these compounds exhibit potent effects. We may 
elect to enter into a partnership to advance the development of our 5HT2c agonist program, either for the treatment of obesity, 
schizophrenia, or both indications, as well as for certain programs involving MultiStem. Further, small molecule compounds may be 
used to enhance the production or therapeutic effectiveness of MultiStem or related products. These compounds may increase 
biological potency for certain indications and lead to second or third generation products in the regenerative medicine area.  

We were incorporated in Delaware on October 24, 1995. On June 8, 2007, we merged with a wholly owned subsidiary of BTHC VI, 
Inc., a Delaware corporation, and on August 31, 2007, BTHC VI, Inc. changed its name to Athersys, Inc.

Business Strategy  

Our principal business objective is to discover, develop and commercialize novel therapeutic products for disease indications that 
represent significant areas of clinical need and commercial opportunity. The key elements of our strategy are outlined below:  

•

•

•

•

•

Efficiently Conduct Clinical Development to Establish Clinical Proof of Concept and Biological Activity with our Lead 
Product Candidates. We are conducting a number of clinical studies with the intent to establish proof of concept and/or proof 
of biological activity in a number of important disease areas where the cell therapies would be expected to have benefit – 
including neurological conditions, cardiovascular disease, and inflammatory and immune system dysfunctions. Our focus is 
on conducting well-designed studies early in the clinical development process to establish a robust foundation for subsequent 
development, partnering activity and expansion into complementary areas. We are committed to a rigorous clinical and 
regulatory framework, which we believe has helped us to advance our programs efficiently, providing high quality, 
transparent regulatory submissions. Our discussions with the FDA, EMA, Pharmaceuticals and Medical Devices Agency, or 
PMDA, and other regulatory agencies have resulted in a successful regulatory partnership that has helped to advance our 
programs efficiently. 

Continue to Refine and Improve our Manufacturing and Related Processes and Deepen our Understanding of Therapeutic 
Mechanisms of Action. A key aspect of the cells that comprise the MultiStem product is their expansion capacity ex vivo 
relative to other cell types. This allows for large scale production of the clinical product, which enables greater consistency, 
specificity and cost of goods advantages over other cell therapies. We plan to build on this intrinsic biological advantage by 
continuing to advance and optimize our production and process development approaches, further developing and optimizing 
new manufacturing techniques, and optimizing the plant-to-bedside supply chain to support late-stage development and 
commercialization of MultiStem therapy. Additionally, we will continue to refine our understanding of our products’ 
activities and mechanisms of action to enable optimization of administration and dosing and to prepare the foundation for 
product enhancements and next generation opportunities. 

Enter into Arrangements with Business Partners to Accelerate Development and Value Creation. In addition to our internal 
development efforts, an important part of our product development strategy is to work with collaborators and partners to 
accelerate product development, reduce our development costs, and broaden our commercial access. We have entered into 
licensing and product co-development arrangements with qualified commercial partners to achieve these objectives. We 
anticipate that this strategy will help us to develop a portfolio of high quality product development opportunities, enhance our 
clinical development and commercialization capabilities, and increase our ability to generate value from our proprietary 
technologies. To date, we entered into technology licensing arrangements and established product commercialization and co-
development partnerships with companies such as Chugai, Pfizer, Bristol-Myers Squibb Company, or Bristol-Myers Squibb, 
Johnson & Johnson, Wyeth Pharmaceuticals, Inc., RTI Surgical, Inc., or RTI, and other companies. Licensing partnerships 
generate revenue and provide capital that allows us to advance our programs further in development. 

Efficiently Explore New High Potential Therapeutic Applications, Leveraging Third-Party Research Collaborations and our 
Results from Related Areas. Our product candidates have shown promise in multiple disease areas, including in treating 
neurological conditions, cardiovascular disease, inflammatory and immune disorders, and other areas. We are committed to 
exploring potential clinical indications where our therapies may achieve best-in-class profile, and where we believe we can 
effectively address significant unmet medical needs. In order to achieve this goal, over the past decade, we established 
collaborative research relationships with investigators from many leading research and clinical institutions across the United 
States and Europe, including the Cleveland Clinic, Case Western Reserve University, University of Minnesota, Georgia 
Regents University, the University of Oregon Health Sciences Center, the University of Texas Health Science Center at 
Houston, the University of Pittsburgh Medical Center, the Katholieke Universiteit Leuven, or KUL, University of 
Regensburg, and other institutions. Through this network of collaborations, we studied MultiStem therapy in a range of 
preclinical models that reflect various types of human disease or injury in the neurological, cardiovascular and immunological 
areas. These collaborative relationships have enabled us to cost effectively explore where MultiStem cell therapy may have 
relevance, and how it may be utilized to advance treatment over current clinical care. Additionally, we have shown that we 
can leverage clinical safety data and preclinical results from some programs to support accelerated clinical development 
efforts in other areas, saving substantial development time and resources compared to traditional drug development where 
generally each program is separately developed. 

Continue to Expand our Intellectual Property Portfolio. We have a broad intellectual property estate that covers our 
proprietary products and technologies, as well as methods of production and methods of use. Our intellectual property is 
important to our business and we take significant steps to protect its value. We have ongoing research and development 
efforts, both through internal activities and through collaborative research activities with others, which aim to develop new 
intellectual property and enable us to file patent applications that cover new applications of our existing technologies or 
product candidates, including MultiStem cells and other opportunities. We currently have approximately 160 patents related 
to our stem cell technologies and cell therapy applications providing protection in the United States, Europe, Japan and other 
areas, and we have 54 patents associated with our other technologies and small molecule programs.

Our Current Programs  

By applying our proprietary MultiStem cell therapy product, we established therapeutic product development programs treating 
neurological conditions, cardiovascular disease, inflammatory and immune disorders, and other conditions. Our programs in the 
clinical development stage include the following:  

• Ischemic Stroke: In our ongoing Phase 2 clinical study, we are evaluating the administration of MultiStem cell 
therapy to patients that have suffered an ischemic stroke. In contrast to treatment with the thrombolytic tPA, which must be 
administered within three to four hours after a stroke, we are treating patients one to two days after the stroke has occurred. 
In preclinical studies, administration of a single dose of MultiStem therapy, even one week after a stroke, resulted in 
significant and durable improvements. This double blind, placebo-controlled trial is being conducted at leading stroke 
centers across the United States and Europe. Enrollment was completed in December 2014. We anticipate announcing the 
interim safety and initial efficacy results in April 2015, following the ninety-day patient evaluation and receipt of the 
unblinded clinical data. Also, in February 2015, we established a collaboration with Chugai to develop and commercialize 
MultiStem for the treatment of ischemic stroke in Japan.  

• Acute Myocardial Infarction: We evaluated the administration of MultiStem to patients that suffered an AMI in a 

Phase 1 clinical study. The results of this study demonstrated a favorable safety profile and encouraging signs of 
improvement in heart function among patients that exhibited severely compromised heart function prior to treatment. This 
data was published in a leading peer reviewed scientific journal, and one-year follow-up data suggested that the benefit 
observed was sustained over time. We were awarded a grant for up to $2.8 million to support the advancement of this 
clinical program, and we are completing preparations for the launch of this Phase 2 clinical study, which we anticipate will 
commence in the second quarter of 2015.  

• Acute Respiratory Distress Syndrome: We were awarded a grant for up to approximately £2.0 million to support an 

initial trial to treat patients suffering from ARDS. ARDS is a serious immunological and inflammatory condition 
characterized by widespread inflammation in the lungs. ARDS can be triggered by pneumonia, sepsis, or other trauma and 
represents a major cause of morbidity and mortality in the critical care setting. The medical need for a safe and effective 
treatment of ARDS is significant due to its high mortality rate, and it annually affects approximately 400,000 to 500,000 
patients in Europe, the United States and Japan, together. The grant supporting this Phase 2a clinical trial was awarded by 
Innovate UK to our subsidiary, Athersys Limited in the United Kingdom, or UK, in conjunction with Catapult. We are 
currently preparing for the trial, which we anticipate will commence in the second half of 2015.  

• Hematopoietic Stem Cell Transplant / GvHD: We completed a Phase 1 clinical study of the administration of 
MultiStem cells to patients suffering from leukemia or certain other blood-borne cancers in which patients undergo 
radiation therapy and then receive a hematopoietic stem cell transplant. Such patients are at significant risk for serious 
complications, including graft-versus-host disease, or GvHD, an imbalance of immune system function caused by 
transplanted immune cells that attack various tissues and organs in the patient. Data from the study demonstrated the safety 
of MultiStem cells in this indication and suggested that the therapy may have a beneficial effect in reducing the incidence 
and severity of GvHD, as well as providing other benefits. The MultiStem product has been designated as an orphan drug 
for the GvHD prophylaxis indication by both the FDA and EMA, which may provide market exclusivity and other 
substantial incentives and benefits. We have interacted with both the FDA and EMA to finalize the design of a single 
registration study. In February 2015, the MultiStem product was granted Fast Track designation by the FDA for 
prophylaxis therapy against GvHD following hematopoietic cell transplantation. Currently, we are staging this program for 
future registration-directed development dependent on our other clinical programs and the achievement of certain business 
development and financial objectives.  

• Inflammatory Bowel Disease: MultiStem therapy is being evaluated in a Phase 2 clinical study involving 

administration of MultiStem to patients suffering from UC, the most common form of IBD. This study is being concluded 
by our collaborative partner, Pfizer, and we released interim results in April 2014. Data collection for the study has run 
through 2014 to complete the secondary evaluations, and subsequent analysis, such as biomarker evaluation and one year 
safety assessment, are being completed by Pfizer in 2015. The interim results obtained from the trial showed that a single 
administration of MultiStem to a patient population with longstanding, chronic advanced disease failed to show a 
meaningful clinical effect at the eight-week evaluation period. Despite not showing a significant improvement compared to 
placebo in the primary efficacy endpoints, the MultiStem therapy demonstrated favorable safety and tolerability in the 
eight weeks following treatment. Furthermore, at four weeks, patients getting MultiStem treatment had a significantly 
higher proportion of rectal bleeding responders than placebo patients, suggesting the possibility of a transient effect from 
the single MultiStem dose. In the event that Pfizer does not move forward with the program, development and 
commercialization rights would revert to us.  

6

  
In addition to the programs described above, we are also conducting or supporting clinical activity in other areas, such as solid organ 
transplant, which is an investigator initiated study being conducted at a leading transplant center in Europe. We are also engaged in 
the preparation stages for translational and clinical studies in other targeted areas.  

In addition to our current and anticipated clinical development activities, we are engaged in preclinical development and evaluation of 
MultiStem therapy in other neurological, cardiovascular and inflammatory and immune disease areas, as well as certain other 
indications. We conduct such work both through our own internal research efforts and through a broad global network of 
collaborators.  

We are routinely in discussions with third parties about collaborating in the development of MultiStem therapy for various programs 
and may enter into one or more business partnerships to advance these programs over time.  

We also partnered with RTI on the development of products for certain orthopedic applications using our stem cell technologies in the 
bone graft substitutes market. We began recognizing royalty revenue from product sales in 2014 and may receive other payments 
upon the successful achievement of certain commercial milestones.  

We are also engaged in the development of novel small molecule therapies to treat obesity and other conditions, such as 
schizophrenia. Currently, we are focused on the development of potent, highly selective compounds that act through stimulation of a 
specific receptor in the brain, the 5HT2c serotonin receptor. We are conducting preclinical evaluation of novel compounds that we 
developed that exhibit favorable attributes, including outstanding receptor selectivity, as well as greater potency and activity than 
other 5HT2c agonists. We also demonstrated our compounds are complementary with other agents that have been approved by the 
FDA and believe these compounds could achieve best in class weight loss, along with a superior safety and tolerability profile. 
Furthermore, we evaluated certain compounds in preclinical models of schizophrenia that exhibit an attractive selectivity profile and 
also observed that these compounds exhibit potent effects. We may elect to enter into a partnership to advance the development of our 
5HT2c agonist program, either for the treatment of obesity, schizophrenia, or both indications, as well as for certain programs 
involving MultiStem.  

Regenerative Medicine Programs  

MultiStem — A Novel Therapeutic Modality  

We are developing our MultiStem therapy, a proprietary non-embryonic, allogeneic stem cell product candidate, that we believe has 
potential utility for treating a broad range of diseases and could have widespread application in the field of clinical regenerative 
medicine. Unlike traditional bone marrow transplants or other stem cell therapies, MultiStem cells may be manufactured on a large 
scale and may be administered without tissue matching or the need for immune suppression, analogous to type O blood. Potential 
applications of MultiStem therapy include the treatment of cardiovascular disease, neurological disease or injury and conditions 
involving the immune system, including autoimmune disease and other conditions. We believe that the MultiStem therapy represents 
a significant advancement in the field of stem cell therapy and could have broad clinical application. We currently have open 
Investigational New Drug applications, or INDs, for the study of MultiStem administration in distinct clinical indications, and a 
collaborating institution recently obtained authorization in Europe to initiate a clinical program through an investigator sponsored 
clinical trial application, obtained with our permission and support.  

MultiStem cell therapy is a patented biologic product that is manufactured from human stem cells obtained from adult bone marrow, 
although these cells may alternatively be obtained from other tissue sources, which are also covered under our intellectual property. 
The product consists of a special class of human stem cells that have the ability to express a range of therapeutically relevant proteins 
and other factors, as well as form multiple cell types. Factors expressed by the cells have the potential to deliver a therapeutic benefit 
in several ways, such as the reduction of inflammation, regulation of immune system function, protection of damaged or injured 
tissue, the formation of new blood vessels in regions of ischemic injury and augmentation of tissue repair and healing in other ways. 
Like drugs, these cells may be stored for an extended period of time in frozen form and used off-the-shelf. Following administration, 
the cells have been shown to express multiple therapeutically relevant proteins, but unlike a traditional transplant, are subsequently 
cleared from the body over time, analogous to a drug or biologic.  

7

  
We believe that MultiStem represents a potential best-in-class stem cell therapy because it exhibits each of the following 
characteristics based on research and development conducted to date:  

•

•

•

•

Broad plasticity and multiple potential mechanisms of action. MultiStem cells have a demonstrated ability in animal 
models to form a range of cell types and also appear to be able to deliver therapeutic benefit by producing factors that 
protect tissues against damage and inflammation, as well as enhancing or playing a direct role in revascularization or tissue 
regeneration. 

Large scale production. Unlike conventional stem cells, such as blood-forming or hematopoietic stem cells, mesenchymal 
stem cells, or other cell types, MultiStem cells may be produced on a large scale, processed, and cryogenically preserved, 
and then used clinically in a rapid and efficient manner. Material obtained from a single donor may be used to produce 
hundreds of thousands or millions of individual doses, representing a yield far greater than other stem cells have been able 
to achieve. 

“Off-the-shelf” utility. Unlike traditional bone marrow or hematopoietic stem cell transplants that require extensive genetic 
matching between donor and recipient, MultiStem administration does not require tissue matching or immune suppressive 
drugs. The MultiStem product is administered as a cryogenically preserved allogeneic product, meaning that these cells are 
not genetically matched between donor and recipient. This feature, combined with the ability to establish large MultiStem 
banks, could make it practical for clinicians to efficiently deliver stem cell therapy to a large number of patients. 

Safety. Other stem cell types, such as undifferentiated embryonic stem cells or induced pluripotent stem cells have shown 
the capacity to form ectopic tissue or teratomas, which are tumor-like growths. These could pose serious safety risks to 
patients. In contrast, MultiStem cells have shown a consistent and favorable safety profile that has been compiled over 
several years of preclinical study in a range of animal models by a variety of investigators and that is supported by clinical 
data generated to date. 

At each step of the MultiStem production process, cells are analyzed according to pre-established criteria to ensure that a consistent, 
well characterized product candidate is produced. Cells are harvested from a pre-qualified, healthy, consenting donor and these cells 
are then expanded to form a master cell bank from which we subsequently produce clinical grade material. We demonstrated the 
ability to harvest cells that meet our rigorous criteria from healthy donors with a high degree of consistency. Furthermore, in multiple 
animal models, MultiStem has been shown to be non-immunogenic, and is administered without the genetic matching that is typically 
required for conventional bone marrow or stem cell transplantation.  

The distinctive profile of the MultiStem product allows us to pursue multiple high value commercial opportunities from a single 
product platform. Based upon work that we and independent collaborators have conducted over the past several years, we believe that 
MultiStem cells have the potential to treat a range of distinct disease indications, including ischemic injury and cardiovascular 
disease, certain types of neurological conditions or injury, autoimmune disease, transplant support (including in oncology patients and 
solid organ transplant areas), and a range of orphan disease indications. As a result, we believe we will be able to leverage our 
foundation of safety and efficacy data to add clinical indications efficiently, enabling us to reduce development costs and timelines 
substantially.  

MultiStem for Treating Neurological Conditions, Cardiovascular Disease, and Inflammatory and Immune Disorders  

Healthcare represents a significant part of the global economy. In the United States, it represented approximately 17.2% of all 
economic activity in 2013, or about $2.9 trillion dollars, annually. However, the United States, along with many other nations, is 
experiencing an unprecedented demographic shift that is resulting in a significantly expanded population of older individuals. 
According to United States Census data, in the next few years there will be a dramatic increase in the number of individuals over the 
age of 65, as this segment of the population increases from 40.2 million individuals in 2010 to more than 72 million people in 2030, 
representing an increase of approximately 80%. The aging of the population will create enormous financial pressure on the healthcare 
system in the United States and other countries around the world, resulting in significant clinical challenges, but also resulting in 
substantial commercial opportunities.  

Data from the National Center for Health Statistics shows that as people get older, they are more susceptible to a variety of age related 
conditions, including heart disease, stroke, certain forms of cancer, diabetes, progressive neurological disorders, various chronic 
inflammatory and immune conditions, renal disease and a range of others. As a consequence, as people get older they spend far more 
on healthcare. On average they spend four to ten times more on healthcare annually at age 65 or beyond than when they were younger 
and more healthy. According to the Alliance for Aging Research, 83% of healthcare spending is associated with chronic conditions, 
and other research shows that 62% of healthcare spending is associated with multiple chronic conditions. Traditional medical 
approaches have failed to adequately address this problem.  

8

  
  
  
  
  
 
 
 
 
We have worked with independent investigators at a number of leading institutions, such as the Cleveland Clinic, Case Western 
Reserve University, University of Minnesota, the National Institutes of Health, the Georgia Regents University, the University of 
Oregon Health Sciences Center, the University of Texas Health Science Center at Houston, KUL, the University of Pittsburgh 
Medical Center, University of Regensburg and other institutions. Through this network of collaborations, we studied the impact of 
MultiStem cell therapy in a range of preclinical models that reflect various types of human disease or injury in the neurological, 
cardiovascular, and immunological areas. To date, we and our collaborators have published research results illustrating the potential 
benefits of MultiStem cell therapy in a range of indications including ischemic stroke, traumatic brain injury, or TBI, brain damage 
due to restricted blood flow in newborns, spinal cord injury, myocardial infarction, vascular disease, acute pulmonary distress, and 
bone marrow transplant support/GvHD. In addition, we have explored and intend to further explore MultiStem administration in the 
treatment of a range of other conditions, including other forms of cardiovascular disease, neurological conditions, and immune related 
disorders.  

Based on preclinical results, we have advanced MultiStem therapy to clinical development stage in several clinical indications or 
disease areas: treatment for stroke caused by a blockage of blood flow in the brain; treatment of damage caused by myocardial 
infarction; support in the hematologic malignancy setting to reduce certain complications associated with traditional bone marrow or 
hematopoietic stem cell, or HSC, transplantation; and treatment of IBD, initially focused on UC. Additionally, in collaboration with a 
leading transplant center in Europe, we advanced a program in the solid organ transplant area into clinical development and plan to 
begin clinical development for treatment of ARDS.  

We may expand to other clinical indication areas as results warrant and resources permit.  

Neurological Injury and Disease — MultiStem for Ischemic Stroke  

Another focus of our regenerative medicine program is MultiStem administration for the treatment of neurological injury as a result 
of acute or chronic conditions. Neurological injury and disease represents an area of significant unmet medical need, a major burden 
on the healthcare system, and also represents a huge commercial opportunity.  

Many neurological conditions require extensive long-term therapy, and many require extended hospitalization and/or institutional 
care, creating an enormous cost burden. Stroke represents an area where the clinical need is particularly significant, since it represents 
a leading cause of death and significant long term disability. We have published research with independent collaborating investigators 
that demonstrates that MultiStem administration conveys biological benefits in preclinical models of ischemic stroke, as well as other 
models of neurological damage and injury, including TBI, neonatal hypoxic ischemia (a cause of neurological damage in infants), and 
spinal cord injury. We also conducted preclinical work in other neurological areas, and have been awarded grants to support work in 
areas such as the indications described above and for evaluating the potential of MultiStem cells to address chronic conditions such as 
Multiple Sclerosis, or MS, or Parkinson’s disease. Our research has shown that MultiStem cells convey benefits through distinct 
mechanisms, including reducing inflammatory damage, protecting at risk tissue at the site of injury, and through direct neurotrophic 
effects that stimulate the recovery of damaged neurons. As a result, we believe that MultiStem therapy may have relevance to 
multiple forms of neurological injury and disease.  

Our initial clinical focus in the neurological area involves evaluating MultiStem administration to treat ischemic stroke. Currently, 
there are approximately 800,000 individuals in the United States that suffer a stroke each year, more than two million stroke victims 
in the United States, Europe and Japan combined and approximately 15 million people that suffer a stroke each year globally. The 
vast majority of these (approximately 85% to 90%) are ischemic strokes, that are caused by a blockage of blood flow in the brain, that 
cuts off the supply of oxygen and nutrients, and can result in tissue loss and neurological damage, as well as long term or permanent 
disability. The remaining 10% to 15% are hemorrhagic strokes, which occur when a blood vessel bursts and bleeding into the brain 
ensues.  

Recent progress toward the development of safer and more effective treatments for ischemic stroke has been disappointing. Despite 
the fact that ischemic stroke is one of the leading causes of death and disability in the United States, there has been little progress 
toward the development of treatments that improve the prognosis for stroke victims. The only FDA-approved drug currently available 
for ischemic stroke is the anti-clotting factor, tPA. According to current clinical guidelines, tPA must be administered to stroke 
patients within several hours after the occurrence of the ischemic stroke to remove the clot while minimizing potential risks, such as 
bleeding into the brain. Administration of tPA after three to four hours is not recommended, since it can cause cerebral bleeding or 
even death. As a consequence of this limited time window, only a small percentage of stroke victims are treated with the currently 
available therapy—most simply receive supportive or “palliative” care. The long-term costs of stroke are substantial, with many 
patients requiring extended hospitalization, extended physical therapy or rehabilitation (for those patients that are capable of entering 
such programs), and many require long-term institutional or family care.  

9

  
In preclinical studies conducted by investigators, including at the University of Minnesota, the Georgia Regents University, and the 
University of Texas Health Science Center at Houston, significant functional improvements have been observed in rodents that have 
undergone an experimentally induced stroke, or that have incurred significant neurological damage due to similar types of ischemic 
events, such as a result of neonatal hypoxic ischemia or TBI, and then received MultiStem treatment. Published research has 
demonstrated that MultiStem administration even one week after a surgically induced stroke results in substantial long-term 
therapeutic benefit, as evidenced by the improvement of treated animals compared with controls in a battery of tests examining 
mobility, strength, fine motor skills, and other aspects of neurological functional improvement.  

Based on the research conducted by us and our collaborators, we believe MultiStem treatment conveys significant benefits through 
several mechanisms, including reduction of inflammation and immune system modulation in the ischemic area, and the protection and 
rescue of damaged or injured cells, including neuronal tissue. Research results presented at the 2011 and 2012 American Heart 
Association International Stroke Conference by collaborators from the University of Texas Health Science Center at Houston 
demonstrated that MultiStem administration 24 hours following a stroke reduced inflammatory damage in the brain and resulted in 
significant functional improvement, and that some of these results were achieved by reducing the inflammatory response emanating 
from the spleen. These results confirm that MultiStem treatment is well tolerated, does not require immunosuppression and results in 
a robust and durable therapeutic benefit, and are consistent with prior results that show MultiStem can provide significant benefits 
even when administered up to one week after the initial stroke event.  

We recently completed enrollment in our double-blind, placebo-controlled Phase 2 clinical trial exploring the administration of 
MultiStem to patients that have suffered an ischemic stroke in the United States and Europe. In this trial, MultiStem was administered 
one to two days after the stroke had occurred. If shown to be safe and effective, this would represent a significant extension of the 
treatment window relative to existing standard of care and could provide an important new therapeutic option for stroke patients. We 
believe that the potential market for a new therapy to treat stroke could be $15 to $20 billion or more annually. We anticipate 
announcing the interim safety and initial efficacy results in April 2015, following the ninety-day patient evaluation and receipt of the 
unblinded clinical data.  

We are also interested in the application of MultiStem for other neurological indications that represent areas of significant unmet 
medical need, such as TBI, which represents the leading cause of disability among children and young adults, and a leading cause of 
death. Approximately 1.7 million cases of TBI are seen in the United States each year, nearly half a million cases of which are 
children age 0 to 14 years old. The United States Center for Disease Control and Prevention, or CDC, estimates that more than 
5.3 million individuals are living with a disability and have a long-term or lifelong need for help to perform activities of daily living 
as a result of a TBI. The annual direct and indirect costs for TBI are approximately $60 billion a year, according to the National 
Institute of Neurological Disorders and Stroke, which is part of the National Institutes of Health. In preclinical studies of TBI, 
administration of MultiStem dramatically reduced the extent of damage caused by a TBI, and promoted accelerated healing of the 
blood-brain barrier. In 2012, we announced grant funding of up to $3.6 million to further advance our MultiStem programs and cell 
therapy platform, including further development of MultiStem therapy for the treatment of TBI and further development of our cell 
therapy formulations and manufacturing capabilities. We received authorization in 2013 to advance our TBI program into the second 
phase of the two-stage federal grant award and expect to complete this research mid-2015.  

We are also conducting preclinical work exploring the application of MultiStem treatment in other neurological indications. In 2010, 
we and collaborators at the Center for Stem Cell and Regenerative Medicine and Case Western Reserve University were awarded 
$1.0 million through the Ohio Third Frontier Biomedical Program to support preclinical and translational research into the MultiStem 
treatment of spinal cord injury, or SCI. In 2012, we presented data at the Annual Society for Neuroscience meeting that demonstrated 
that intravenous MultiStem administration one day after SCI results in statistically significant and sustained improvements in gross 
locomotor function, fine locomotor function and bladder control compared to control treated animals.  

Over the past several years, we have been utilizing grant funding to investigate the potential for MultiStem treatment for chronic 
progressive multiple sclerosis, or MS, based on initial results in preclinical models. In 2012, in collaboration with scientists from Case 
Western Reserve University, and with the support of Fast Forward and the National Multiple Sclerosis Society, we reported research 
results that demonstrate the potential benefits of MultiStem therapy for treating MS. In standard preclinical models of MS, researchers 
observed that MultiStem administration results in sustained behavioral improvements, arrests the demyelination process that is central 
to the pathology of MS, and supports remyelination of affected axons. We have continued to advance our MS program with support 
from Fast Forward.

Cardiovascular Disease — Evaluating MultiStem for Treating Damage from a Heart Attack 

Cardiovascular disease is an area of significant clinical need and its prevalence is expected to grow in the years ahead. Despite 
treatment advances in recent years, cardiovascular disease remains the leading cause of death, and represents one of the leading 
causes of disability around the world. In the United States, approximately 915,000 people suffer a heart attack each year, and 
approximately 5.1 million individuals in the United States are currently suffering from heart failure in 2010, according to the 
American Heart Association 2014 Statistical Update. Another 8.5 million people suffer from peripheral arterial disease, which is 
associated with significant morbidity and mortality. In addition, there were approximately 788,000 deaths that occurred from all 
forms of cardiovascular disease, including 443,000 individuals that died as a result of coronary heart disease or heart failure. 
According to projections published recently by the American Heart Association in February 2011 in the journal Circulation, 
aggregate costs for treating heart disease in the United States are expected to soar in the coming years. In 2010, annual direct costs for 
treating cardiovascular disease were $273 billion, but by 2030 these are expected to nearly triple, to a projected $818 billion per year. 
This increase will occur primarily as a result of the aging population, and may not fully reflect the impact of the dramatic escalation in 
obesity rates that has occurred for both adults and children in recent years, which could further exacerbate the long-term challenges 
and increase costs associated with cardiovascular disease and other conditions.  

In a Phase 1 clinical trial, we explored MultiStem treatment for damage caused by AMI. Myocardial infarction is one of the leading 
causes of death and disability in the United States and is caused by the blockage of one or more arteries that supply blood to the heart. 
Such blockages can be caused, for example, by the rupture of an atherosclerotic plaque deposit. A variety of risk factors are 
associated with an elevated risk of myocardial infarction or atherosclerosis, including age, high blood pressure, smoking, sedentary 
lifestyle and genetics. While advances in the diagnosis, prevention and treatment of heart disease have had a positive impact, there is 
clearly room for improvement—myocardial infarction remains a leading cause of death and disability in the United States and the rest 
of the world.  

MultiStem treatment has been studied in validated animal models of AMI, including at both the Cleveland Clinic and the University 
of Minnesota. Investigators demonstrated that the administration of allogeneic MultiStem cells into the hearts of animals damaged by 
experimentally induced heart attacks resulted in significant functional improvement in cardiac output and other functional parameters 
compared with animals that received placebo or no treatment. Furthermore, the administration of immunosuppressive drug was not 
required and provided no additional benefit in this study, and supports the concept of using MultiStem cells as an allogeneic product. 
We completed additional preclinical studies in established pig models of AMI using catheter delivery and examining various factors 
such as the route and method of MultiStem administration, dose ranging, and timing of treatment.  

We conducted a multicenter, open-label Phase 1 clinical trial in this indication and the results showed that MultiStem treatment was 
well tolerated at all dose levels, exhibited a favorable safety profile, and that patients who received MultiStem treatment exhibited 
meaningful improvements in cardiovascular function, including left ventricular ejection fraction, wall motion scores, and other 
parameters. These results were published by Circulation Research in 2012.  

We are preparing for a Phase 2 clinical study of MultiStem administration to patients that have suffered an AMI, which we anticipate 
will commence in the second quarter of 2015. In 2013, we were awarded a grant from the National Institutes of Health for up to $2.8 
million to support the funding of the program.  

Immunological Disorders — MultiStem for Acute Pulmonary Distress, IBD and HSC Transplant Support  

Inflammatory and immune disorders represent a significant burden to society. There are over 80 recognized autoimmune disorders, 
which are conditions caused by an acute or chronic imbalance in the immune system. In these conditions, cells of the immune system 
begin to attack certain tissues or organs in the body, resulting in tissue damage and loss of function. Some inflammatory and immune 
conditions are associated with age-related conditions (e.g., rheumatoid arthritis), but some are due to other causes that may be genetic, 
environmental or a combination of both (e.g., Type 1 diabetes, IBD). Still other conditions may reflect complications associated with 
the treatment of other conditions (e.g., GvHD, a frequent complication associated with transplant procedures used to treat leukemia or 
related blood-borne cancers). Each of these conditions shares certain biological characteristics, in that the immune system imbalance 
results from the inappropriate activation of certain populations of immune cells that subsequently results in significant tissue damage 
and destruction. This immune imbalance may result in a complex cascade of inflammation that can result in pain, progressive tissue 
deterioration and loss of function. While currently available immunomodulatory drugs have proven to be effective for some patients, 
they have failed to adequately address the needs of many other patients that suffer from inflammatory and immune disorders.  

In multiple studies, MultiStem cells have shown potent immunomodulatory properties, including the ability to reduce active 
inflammation through various modes of action, stimulate tissue repair and restore immune system balance. Accordingly, we believe 
that MultiStem therapy could have broad application in the area of treating immune system disorders, including certain acute 
inflammatory conditions, autoimmune diseases and other conditions.  

11

  
In animal models, MultiStem cells have demonstrated an ability to reduce the severity of pulmonary distress, reduce alveolar edema 
and return lung endothelial permeability to normal. Intravenous MultiStem treatment early following the onset of the condition may 
ameliorate the initial hyper-inflammation and reduce the fibrotic activity that follows, thereby speeding the return to and improving 
the likelihood of more normal lung function, and helping patient recovery. In January 2015, we announced that our subsidiary, 
Athersys Limited, received a grant award of up to approximately £2.0 million from Innovate UK to support a Phase 2a clinical study 
evaluating the administration of MultiStem cell therapy to ARDS patients. We intend to initiate this study in the second half of 2015.  

ARDS is a serious immunological and inflammatory condition characterized by widespread inflammation in the lungs. ARDS can be 
triggered by pneumonia, sepsis, or other trauma and represents a major cause of morbidity and mortality in the critical care setting. It 
has significant implications, as it prolongs intensive care unit, or ICU, and hospital stays, and requires convalescence in the hospital 
and rehabilitation. There are limited interventions and no effective drug treatments for ARDS, making it an area of high unmet 
clinical need with high treatment costs. Given ARDS high treatment costs, a successful cell therapy could be expected to generate 
significant savings for the healthcare system by reducing days on a ventilator, days in the intensive care unit and total days in the 
hospital, and importantly, could reduce mortality and improve quality of life for those suffering from the condition. The medical need 
for a safe and effective treatment of ARDS is significant due to its high mortality rate, and it affects annually approximately 33,000 
patients in the UK and 400,000 to 500,000 patients in Europe, the United States and Japan, alone. 

Another area of focus is the use of MultiStem cells as adjunctive treatment for HSC/bone marrow transplant used as therapy in 
hematologic malignancy. For many types of cancer, such as leukemia or other blood-borne cancers, treatment typically involves 
radiation therapy or chemotherapy, alone or in combination. Such treatment can substantially deplete the cells of the blood and 
immune system, by reducing the number of stem cells in the bone marrow from which they arise. The more intense the radiation 
treatment or chemotherapy, the more severe the resulting depletion is of the bone marrow, blood, and immune system. Other tissues 
may also be affected, such as cells in the digestive tract and in the pulmonary system. The result may be severe anemia, 
immunodeficiency, substantial reduction in digestive capacity, and other problems that may result in significant disability or death.  

One strategy for treating the depletion of bone marrow is to perform a peripheral blood stem cell transplant or a bone marrow 
transplant. This approach may augment the patient’s ability to form new blood and immune cells and provide a significant survival 
advantage. However, finding a closely matched donor is frequently difficult or even impossible. Even when such a donor is found, in 
many cases there are immunological complications, such as GvHD, which may result in serious disability or death.  

Working with leading experts in the stem cell and bone marrow transplantation field, we studied MultiStem in animal models of 
radiation therapy and GvHD. In multiple animal models, MultiStem cells have been shown to be non-immunogenic, even when 
administered without the genetic matching that is typically required for conventional bone marrow or stem cell transplantation. 
Furthermore, in animal model systems testing immune reactivity of T-cells against unrelated donor tissue, MultiStem has been shown 
to suppress the T-cell-mediated immune responses that are an important factor in causing GvHD. MultiStem-treated animals also 
displayed a significant increase in survival relative to controls. As a result, we believe that MultiStem administration in conjunction 
with or following standard HSC transplantation may have the potential to reduce the incidence or severity of complications and may 
enhance gastrointestinal function, which is frequently compromised as a result of radiation treatment or chemotherapy.  

We completed a Phase 1 clinical trial examining the safety and tolerability of a single dose or repeat dosing of MultiStem cells 
administered intravenously to patients receiving a bone marrow or hematopoietic stem cell transplant as part of their treatment of 
leukemia or other hematological condition. The trial was an open label, multicenter trial that involved leading experts in the field of 
bone marrow transplantation. In February 2012, we announced the top-line results from the trial. We observed a consistent safety 
profile in both the single and multiple dose arms of the study, and at all dose levels tested. Although the trial was not specifically 
designed to demonstrate efficacy, we also observed clinically meaningful improvement in medically important parameters relative to 
historical clinical experience, including reduced incidence and severity of acute GvHD, improved relapse free survival, no graft 
failures, and enhanced engraftment rates relative to other forms of treatment.  

We were granted orphan drug designation by the FDA and EMA for MultiStem treatment in the prevention of GvHD. We met with 
the FDA to review the results from the Phase 1 trial and discuss plans for the next phase of clinical development, which we intend to 
be a Phase 2-3 study of MultiStem for GvHD prophylaxis and HSC transplant support. Based on FDA feedback, we are currently 
working to finalize our trial design as we plan and prepare for trial initiation. The initiation of the trial will depend on the progress in 
our clinical trials and the achievement of certain business development and financial objectives. In February 2015, we were granted 
designation by the FDA as a Fast Track product for prophylaxis therapy against GvHD following hematopoietic cell transplantation.  

12

  
In 2009, we entered into a collaboration agreement with Pfizer to develop and commercialize MultiStem therapy for the treatment of 
IBD for the worldwide market. IBD is a group of inflammatory and autoimmune conditions that affect the colon and small intestine, 
typically resulting in severe abdominal pain, weight loss, vomiting and diarrhea. The most common forms of the disease include UC and 
Crohn’s disease, which are estimated to affect four million people or more in the United States, five major European markets (UK, 
Germany, France, Italy and Spain) and Japan. Chronic IBD can be a severely debilitating condition, and advanced cases may require 
surgery to remove the affected region of the bowel, and may also require temporary or permanent colostomy or ileostomy. In many 
cases, surgery does not achieve a permanent cure, and patients suffer a return of the disease. In 2011, enrollment commenced in our 
double-blind, placebo-controlled Phase 2 clinical study evaluating MultiStem administration to patients suffering from UC, and 
enrollment was completed in December 2013. In April 2014, we and Pfizer reported the initial interim results of the trial. The interim 
results obtained from the trial showed that a single administration of MultiStem to a patient population with longstanding, chronic 
advanced disease failed to show a meaningful clinical effect at the eight-week evaluation period. Despite not showing a significant 
improvement compared to placebo in the primary efficacy endpoints, the MultiStem therapy demonstrated favorable safety and 
tolerability in the eight weeks following treatment. Furthermore, at four weeks, patients getting MultiStem treatment had a significantly 
higher proportion of rectal bleeding responders than placebo patients, suggesting the possibility of a transient effect from the single 
MultiStem dose. However, given the limited evidence of benefit in this study, it remains possible that MultiStem is not beneficial or well 
suited to this indication. In the event that Pfizer does not move forward with the program, development and commercialization rights 
would revert to us.  

Pharmaceutical Programs  

Novel 5HT2c agonists for the treatment of obesity and other conditions  

Obesity is a substantial contributing factor to a range of diseases that represent the major causes of death and disability in the developed 
world today. Individuals that are clinically obese have elevated rates of cardiovascular disease, stroke, certain types of cancer and 
diabetes. According to the CDC, the incidence of obesity in the United States has increased at an epidemic rate during the past 20 years. 
CDC now estimates that almost 70% of all Americans are overweight, including more than one-third that are considered clinically 
obese. The percentage of young people that are overweight has more than tripled since 1980. There has also been a dramatic rise in the 
rate of obesity in Europe and Asia. Despite the magnitude of this problem, current approaches to clinical obesity are largely ineffective, 
and we are aware of relatively few new therapeutic approaches in clinical development.  

We are developing novel pharmaceutical treatments for obesity, which are compounds designed to act by stimulating a key receptor in 
the brain that regulates appetite and food intake—the 5HT2c receptor. The role of this receptor in regulating food intake is well 
understood in both animal models and humans. In 1996, Wyeth launched the anti-obesity drug Redux® (dexfenfluramine), a non-specific 
serotonin receptor agonist that was used with the stimulant phentermine in a combination commonly known as fen-phen. This diet drug 
combination was shown to be highly effective at regulating appetite, reducing food intake, and causing significant weight loss. 
Unfortunately, in addition to stimulating the 5HT2c receptor, Redux also stimulated the 5HT2b receptor that is found in the heart, and 
Redux was withdrawn from the market in 1997.  

Since the withdrawal of Redux, several groups have published research and clinical data that implicate stimulation of the 5HT2b 
receptor as the underlying cause of the cardiovascular problems. These findings suggest that highly selective compounds that stimulate 
the 5HT2c receptor, but that do not appreciably stimulate the 5HT2b receptor, could be developed that maintain the desired appetite 
suppressive effects without the cardiovascular toxicity. Recent clinical data supports this hypothesis and also suggests that the 5HT2c 
agonists may also cause a statistically significant reduction in the amount of sugar in the blood, as measured by fasting blood glucose 
and HbA1c levels, which are both clinically relevant measures for patients suffering from diabetes.  

In 2012, the FDA approved Lorcaserin, a 5HT2c agonist, for the treatment of obesity. We believe this represents a significant event for 
our program because it illustrates that the FDA recognizes and agrees with the concept that 5HT2c agonists that display appropriate 
selectivity, biological activity and clinical safety are approvable for indications such as obesity.  

Our drug development program is focused on creating potent and selective orally administered compounds that stimulate the 5HT2c 
receptor, but that avoid the 5HT2b receptor and other receptors, such as 5HT2a, or other receptors that could cause adverse side effects. 
Based on extensive preclinical studies that we conducted with compounds that we generated, we have demonstrated the ability to 
develop compounds that are highly potent and selective for the 5HT2c receptor, and that lack activity at either 5HT2a or 5HT2b. We 
believe that clinical trials will demonstrate that this achievement represents a significant advance in the field, and that the potency and 
selectivity profile displayed by compounds we are developing will result in substantially better efficacy and a cleaner safety and 
tolerability profile, as well as a more convenient dosing schedule than other 5HT2c agonist programs including Lorcaserin. We also 
evaluated certain of our compounds when administered as a monotherapy or in conjunction with other weight loss agents, and have 
observed effectiveness with both approaches. We are conducting preclinical evaluation of novel compounds that we developed that 
exhibit outstanding receptor selectivity and are working toward the selection of a clinical development candidate for this program.  

13

  
Certain potent and highly selective compounds that we developed display a profile that we believe may have utility in treating 
schizophrenia. We evaluated some of these compounds in preclinical models of schizophrenia and have observed that they exhibit 
efficacy in these models.  

We may elect to enter into a partnership to advance the development of our 5HT2c agonist program, either for the treatment of 
obesity, schizophrenia, or both indications, as well as for certain programs involving MultiStem.  

Other Small Molecule Programs & Key Technologies  

In addition to our other programs, we believe that there are significant opportunities for synergy between our small molecule platform 
and related capabilities and our MultiStem technology. Specifically, we believe that substantial opportunities exist for identifying and 
utilizing small molecule modulators of therapeutically relevant biological activity exhibited by MultiStem or other stem cell types. 
We believe that applying our capabilities in both areas could lead to next generation product development opportunities, including 
more potent stem cell based therapies that have been optimized for use in specific indication areas.  

In addition to our current product development programs, we developed our patented RAGE® technology that provides us with the 
ability to produce human cell lines that express specific, biologically well validated drug targets without relying upon cloned and 
isolated gene sequences. While our RAGE technology is not a therapeutic product, it is a commercial technology that we have 
successfully applied for the benefit of our partners and that we also used for our own internal drug development programs. Modern 
drug screening approaches typically require the physical isolation and structural modification of a gene of interest, an approach 
referred to as gene cloning, in order to create a cell line that expresses a drug target of interest. Researchers may then use the 
genetically modified cell line to identify pharmaceutical compounds that inhibit or stimulate the target of interest. The RAGE 
technology enables us to turn on or amplify the expression of a drug target without having to physically clone or isolate the gene. In 
effect, the technology works through the random insertion of tiny, proprietary genetic switches that randomly turn genes on without 
requiring their physical isolation, or any advance knowledge of their structure. This technology provides us with broad freedom to 
work with targets that may be otherwise unavailable as a result of intellectual property restrictions on the use of specific cloned and 
isolated genes. In recent years, we have produced cell lines that express drug targets in a range of disease areas such as metabolic 
disease, infectious disease, oncology, cardiovascular disease, inflammation, and central nervous system disorders. Many of these were 
produced for drug development programs at major pharmaceutical companies that we have collaborated with, such as Bristol-Myers 
Squibb, and some have been produced for our internal drug development programs.  

Collaborations and Partnerships  

Chugai  

In February 2015, we entered into a license agreement with Chugai to develop and commercialize MultiStem cell therapy for 
ischemic stroke in Japan on an exclusive basis. Under the agreement, Chugai will be responsible for the development and 
commercialization of MultiStem for ischemic stroke in Japan, and we will have the primary responsibility for the manufacture of 
product for both clinical and commercial purposes. The parties will coordinate Japanese and global regulatory activities and clinical 
development plans for MultiStem treatment of ischemic stroke.  

Under the terms of the agreement, we received an up-front cash payment of $10 million from Chugai and are entitled to receive a 
potential near-term payment of $7 million tied to the results of our ongoing Phase 2 clinical trial in ischemic stroke. We may also 
receive additional success-based development and regulatory milestones aggregating up to $38 million, as well as potential sales 
milestones of up to 17.5 billion yen (approximately $150 million based on the current exchange rate). With commercialization and 
until the agreement has expired or been terminated, Chugai would pay us royalties on net sales, starting in the low double digits and 
increasing incrementally to the high teens depending on net sales levels. Additionally, we would receive payments for product 
supplied to Chugai.  

The agreement will expire automatically upon the later of the date the licensed product is no longer covered by a patent claim in 
Japan, or the expiration of the re-evaluation period under Article 14-2 of the Pharmaceutical Affairs Law of Japan or any revision or 
replacement, unless extended as set forth below. Additionally, Chugai may terminate the agreement under certain circumstances, 
including for material breach and without cause upon advance written notice. We may terminate the agreement if Chugai fails to 
make certain payments to us and, in certain cases, if there is an uncured material breach of the agreement. Chugai may extend the 
term of the agreement for two successive two-year periods at its sole election, and thereafter, the agreement shall be automatically and 
repeatedly extended for two-year periods unless prior notice is provided by either party not to extend the term.  

14

  
Following termination of the agreement, the licenses granted to Chugai to develop and commercialize MultiStem for ischemic stroke 
in Japan will terminate and ownership of regulatory documents and clinical data will revert to us. Further, our nonexclusive license to 
intellectual property developed by Chugai during the collaboration shall be expanded to include Japan and shall survive termination. 
We maintain rights to develop and commercialize MultiStem for ischemic stroke outside of Japan, and, for all other indications in 
Japan, provided that we give Chugai the first right to negotiate to add such indications to the license in Japan.  

Pfizer  

In 2009, we entered into a collaboration agreement with Pfizer to develop and commercialize MultiStem therapy for the treatment of 
IBD for the worldwide market on an exclusive basis. Under the terms of the agreement, we received a non-refundable up-front cash 
payment of $6.0 million from Pfizer and research funding during the initial phase of the collaboration that ended in 2012. In addition, 
we are also eligible to receive milestone payments of up to $105 million upon the successful achievement of certain development, 
regulatory and commercial milestones, though there can be no assurance that we will achieve these milestones, and no significant 
milestone payments were received as of December 31, 2014. We are responsible for manufacturing and Pfizer pays us for 
manufacturing product for clinical development and commercialization purposes. Pfizer has responsibility for development, 
regulatory and commercialization. We may elect to co-develop with Pfizer, in which case the parties will share development and 
commercialization expenses and profits, if any, on an agreed-upon basis beginning at Phase 3 clinical development. Alternatively, we 
may elect to not co-develop with Pfizer, in which case Pfizer will pay us tiered single-digit royalties on worldwide commercial sales 
of MultiStem IBD products. Any royalties may be subject to certain reductions related to market exclusivity, patent claims and credits 
from sales milestone payments. The duration of royalty payments is on a country-by-country and product-by-product basis, and shall 
continue until the later of the date the licensed product is no longer covered by a patent claim in such country, or twelve years from 
product launch in such country.  

The Pfizer collaboration does not have a specific termination date, but will terminate upon the last to expire royalty term, unless 
terminated earlier by either party. Either party can terminate the agreement for an uncured material breach or default. Pfizer is 
permitted to terminate the agreement upon advance written notice to us in its sole discretion or in the event of certain material 
breaches. We can terminate the agreement if a certain milestone event has not occurred by a defined period of time, or if we 
reasonably believe that Pfizer has failed to satisfy its obligations to progress the development of the program. Following termination 
of the agreement by us, all licenses granted to Pfizer to develop and commercialize MultiStem for IBD will terminate, other than 
certain more limited research licenses, and ownership of regulatory and clinical data will revert to us. Following termination of the 
agreement by Pfizer due to material breach, the licenses granted to Pfizer will remain in effect according to their terms and payments 
to us will be reduced from what was otherwise payable.  

University of Minnesota  

In 2003, we acquired the exclusive rights to the MAPC technology originally developed at the University of Minnesota pursuant to a 
license agreement with the University. Over the past several years, we further developed this technology and the manufacturing of the 
cells for use in ongoing clinical trials. We refer to the lead cell therapy as the MultiStem product platform. We are obligated to pay 
the University of Minnesota a royalty based on worldwide commercial sales of licensed products if covered by a valid licensed patent. 
The low single-digit royalty rate may be reduced if third-party payments for intellectual property rights are necessary or commercially 
desirable to permit the manufacture or sale of the product. The royalty payment obligation and the term of the license agreement 
expire upon the last to expire licensed patent. Based on our current patent portfolio, and absent any continuations, renewals or 
extensions of existing patents, the last licensed patent to expire under the license agreement is currently expected to expire in 2028. 
The license agreement does not have a specific termination date, but the University of Minnesota can terminate the license agreement 
for an uncured event of default, as defined, or upon our bankruptcy and we can terminate the license agreement at any time.  

RTI  

In 2010, we entered into an agreement with RTI to develop and commercialize MAPC technology-based biologic implants for certain 
orthopedic applications in the bone graft substitutes market on an exclusive basis. Under the terms of our RTI agreement, we received 
$5.0 million of license fees in installments during 2010-2012. In accordance with the agreement, we are also eligible to receive an 
additional $35.5 million in cash payments upon the successful achievement of certain commercial milestones, though there can be no 
assurance that such milestones will be achieved, and no significant milestone payments were received as of December 31, 2013. In 
addition, we receive tiered royalties on worldwide commercial sales of implants using our technologies based on a royalty rate 
starting in the mid-single digits and increasing into the mid-teens. We began receiving royalties from RTI in 2014. Royalties may be 
subject to a reduction if third-party payments for intellectual property rights are necessary or commercially desirable to permit the 
manufacture or sale of the product.  

15

  
The term of the agreement is the longer of (i) five years from the effective date in 2010, (ii) two years after the last sale of a licensed 
product, (iii) the last to expire of any past, present or future licensed patent, and (iv) the life of trade secrets applicable to the licensed 
product. Either party can terminate the agreement upon the other party’s bankruptcy or for an uncured material breach. RTI can 
terminate the agreement if our rights to our technology expire such that there is a material effect on the development and 
commercialization of the licensed products. We can terminate the agreement if RTI has not reached a specified target of sales of the 
licensed product within five years of the effective date or a specified target of annual sales each year thereafter.  

Bristol-Myers Squibb  

In 2000, we entered into a collaboration with Bristol-Myers Squibb to provide cell lines expressing well validated drug targets 
produced using our RAGE technology for compound screening and development. This initial collaboration was expanded in 2002 and 
again in 2006, and was in its final phase as amended in 2009. Bristol-Myers Squibb uses the cell lines in its internal drug development 
programs and, in exchange, we receive license fee and milestone payments and will be entitled to receive royalties on the sale of any 
approved products. Depending on the use of a cell line by Bristol-Myers Squibb and the progress of drug development programs 
benefiting from the use of such a cell line, we may receive as much as approximately $5.5 million per cell line in additional license 
fees and milestone payments, though we cannot assure you that any further milestones will be achieved or that we will receive any 
additional milestone payments. As of December 31, 2014, we received an aggregate amount of $2.1 million in milestone payments 
and $9.8 million in license fees since the inception of our collaboration with Bristol-Myers Squibb.  

The Bristol-Myers Squibb collaboration does not have a specific termination date, but will terminate when Bristol-Myers Squibb no 
longer has an obligation to pay us royalties, which obligation generally continues until the later of the expiration of the Bristol-Myers 
Squibb patent covering an approved product and ten years after commercial sales of that product began. If either party breaches its 
material obligations and fails to cure that breach within 60 days after notice from the non-breaching party, the non-breaching party 
may terminate the collaboration.  

Competition  

We face significant competition with respect to the various dimensions of our business. With regard to our efforts to develop 
MultiStem as a novel stem cell therapy, currently, there are a number of companies that are actively developing stem cell products, 
which encompass a range of different cell types, including embryonic stem cells, umbilical cord stem cells, adult-derived stem cells 
and processed bone marrow derived cells.  

Mesoblast Limited, or Mesoblast, is currently engaged in clinical trials evaluating the safety and efficacy of Revascor, an allogeneic 
stem cell product based on mesenchymal stem cell precursors that are obtained from healthy consenting donors. These cells also 
appear to display limited expansion potential and biological plasticity. Additionally, Mesoblast is developing Prochymal, a 
mesenchymal stem cell product candidate that it acquired from Osiris Therapeutics, Inc., and Mesoblast has a partnership with 
Cephalon, Inc., or Cephalon, now owned by Teva Pharmaceuticals, Inc., for treating conditions including congestive heart failure, 
AMI, Parkinson’s disease and Alzheimer’s disease.  

Other public companies are developing stem-related therapies, including Aastrom Biosciences, Inc., or Aastrom, Stem Cells Inc., 
Johnson & Johnson, Celgene Corporation, or Celgene, Advanced Cell Technology, Inc., CRYO-CELL International, Inc., Pluristem 
Therapeutics, Inc., or Pluristem, and Cytori Therapeutics, Inc., or Cytori. In addition, private companies, such as Gamida Cell Ltd., 
Plureon Corporation, NeoStem, Inc., Tigenix NV and others, are also developing cell therapy related products or capabilities. Given 
the magnitude of the potential opportunity for stem cell therapy, we expect competition in this area to intensify in the coming years.  

We also face competition in our efforts to develop compounds for the treatment of obesity. In 2012, two new treatments were 
approved by the FDA for the treatment of obesity, Belviq (Lorcaserin), which was developed by Arena Pharmaceuticals, Inc., or 
Arena, and Qsymia (a proprietary combination of phentermine and topiramate), which was developed by Vivus, Inc., or Vivus. In 
2014, another new drug combination was approved, Contrave (a proprietary combination of naltrexone and bupropion), which was 
developed by Orexigen. Prior to these recent approvals, there was one approved therapeutic product on the market for obesity, 
Xenical (also known as Alli), which is marketed by F. Hoffman - LaRoche Ltd., or Roche. Potential side effects associated with 
taking Xenical / Alli include cramping, intestinal discomfort, flatulence, diarrhea, and leakage of oily stool. Another obesity drug, 
Meridia, was approved for clinical use and marketed by Abbott Pharmaceuticals, but was withdrawn from the market due to concerns 
regarding increased risk of cardiovascular disease and stroke among patients taking the drug.  

16

  
There are many other companies that have previously attempted or are attempting to develop novel treatments for obesity, and a wide 
range of approaches are being taken. Some of these companies include large, multinational pharmaceutical companies such as Bristol-
Myers Squibb, Merck & Co., Inc., Roche, Sanofi, GlaxoSmithKline plc, or GlaxoSmithKline, Eli Lilly and Company and others. 
There are also a variety of biotechnology companies developing treatments for obesity, including Neurosearch, Amgen Inc., or 
Amgen, Regeneron Pharmaceuticals, Inc., Nastech Pharmaceutical Company, Alizyme plc, Amylin Pharmaceuticals, Inc., Neurocrine 
Biosciences, Inc., Shionogi & Co., Ltd., Metabolic Pharmaceuticals Limited, Kyorin Pharmaceutical Co., Ltd., and others. It is likely 
that, given the magnitude of the market opportunity, many companies will continue to focus on the obesity area, and that competition 
will remain high. If we are successful at developing a 5HT2c agonist as a safe and effective treatment for obesity, it is likely that other 
companies will attempt to develop safer and more effective compounds in the same class, or will attempt to combine therapies in an 
effort to establish a safer and more effective therapeutic product.  

We believe our most significant competitors are fully integrated pharmaceutical companies and biotechnology companies that have 
substantially greater financial, technical, sales, marketing, and human resources than we do. These companies may succeed in 
obtaining regulatory approval for competitive products more rapidly than we can for our products. In addition, our competitors may 
develop technologies and products that are cheaper, safer or more effective than those being developed by us or that would render our 
technology obsolete. Furthermore, some of these companies may feel threatened by our activities and attempt to delay or impede our 
efforts to develop our products or apply our technologies.  

Intellectual Property  

We rely on a combination of patent applications, patents, trademarks, and contractual provisions to protect our proprietary rights. We 
believe that to have a competitive advantage, we must develop and maintain the proprietary aspects of our technologies. Currently, we 
require our officers, employees, consultants, contractors, manufacturers, outside scientific collaborators and sponsored researchers, 
and other advisors to execute confidentiality agreements in connection with their employment, consulting, or advisory relationships 
with us, where appropriate. We also require our employees, consultants, and advisors that we expect to work on our products to agree 
to disclose and assign to us all inventions conceived during the work day, developed using our property, or which relate to our 
business. We currently have over 200 patents for our technologies.  

We have a broad patent estate with claims directed to compositions, methods of production, and methods of use of certain non-
embryonic stem cells and related technologies. We developed, acquired and exclusively licensed intellectual property covering our 
cell therapy product candidates and other applications in the field. Our broad intellectual property portfolio consists of approximately 
160 issued patents (of which seventeen are United States patents) and more than 180 global patent applications around our stem cell 
technology and MultiStem product platform. This includes fourteen United States patents and more than 100 international patents that 
apply to MAPC and related products, such as MultiStem. The current intellectual property estate, which incorporates additional 
filings and may broaden over time, could provide coverage for our stem cell product candidates, manufacturing processes and 
methods of use through 2030 and beyond. Furthermore, an extended period of market exclusivity may apply for certain products (e.g., 
exclusivity periods for orphan drug designation or biologics).  

We have been active in the development, improvement and protection of our intellectual property portfolio through our prosecution 
efforts, collaborative research efforts, and in-licensing, among other things. From time-to-time, we will also engage in adversarial 
processes, such as interference or litigation, to protect or advance certain patents or applications. These activities represent an 
important cost of doing business, and can result in successes and setbacks due to the nature of the processes. For example, over the 
past several years, we have been involved in several proceedings in the United States with a third party focused on a technology 
developed after the MAPC technology. In an earlier proceeding, our success resulted in the issuance of a patent. However, in a more 
recent proceeding, an interference board ruled that this patent and another application of ours should be cancelled, but such ruling 
may be advanced into an appeal process. Over time, we expect to be involved in similar proceedings with the objective of developing 
the portfolio to support and protect development and commercialization of our or our licensees’ cell therapy products.  

We have established a broad intellectual property portfolio related to our small molecule product candidates and functional genomics 
technologies. We have a broad patent estate with claims directed to compositions, methods of making, and methods of using our 
small molecule drug candidates. We have six United States patents and three patent applications with broad claims directed to 
selective 5HT2c agonists discovered at Athersys that currently provide patent coverage through as late as 2029. From our Histamine 
H3 program, we have six United States patents with broad claims directed to compounds discovered at Athersys from two distinct 
chemical series that currently provide patent coverage through as late as 2028. In addition, we currently have 37 issued patents (16 
United States patents and 21 international patents) relating to compositions and methods for the RAGE technology that currently 
provide patent coverage through as late as 2020, and five United States patents and nine patent applications relating to human proteins 
and candidate drug targets that we identified through the application of RAGE and to our other technologies that currently provide 
patent coverage through as late as 2022. The RAGE technology was developed by Dr. John Harrington and other Athersys scientists 
internally in the mid-1990s.  

17

  
We believe that we have broad freedom to use and commercially develop our technologies and product candidates. However, in the 
event that we or our collaborators are developing, manufacturing, or selling potential products that are claimed to infringe a third 
party’s intellectual property, a loss in litigation may prevent us from commercializing our products, unless that party grants us rights 
to use its intellectual property. Further, we may not be able to obtain any licenses required under any patents or proprietary rights of 
third parties on acceptable terms, or at all. Even if we were able to obtain rights to the third party’s intellectual property, these rights 
may be non-exclusive, thereby giving our competitors access to the same intellectual property. Ultimately, we may be unable to 
commercialize some of our potential products or may have to cease some of our business operations as a result of patent infringement 
claims, which could severely harm our business.  

Research and Development  

Our research and development costs, which consist primarily of costs associated with external clinical trial costs, preclinical study 
fees, manufacturing costs, salaries and related personnel costs, legal expenses resulting from intellectual property application 
processes, and laboratory supply and reagent costs, were $23.4 million in 2014, $20.5 million in 2013 and $19.6 million in 2012.  

Government Regulation  

Any products we may develop and our research and development activities are subject to stringent government regulation in the 
United States by the FDA and, in many instances, by corresponding foreign and state regulatory agencies. The European Union, or 
EU, has vested centralized authority in the EMA and Committee on Proprietary Medicinal Products, or CPMP, to standardize review 
and approval across EU member nations. In Japan, the PDMA, a division of the Ministry of Health, Labour and Welfare, or MHLW, 
regulates the development and commercialization of medical therapies. Recently, Japan’s parliament enacted new legislation to 
promote the safe and accelerated development of treatments using stem cells. The new regenerative medicine law and revised 
pharmaceutical affairs law define products containing stem cells as regenerative medicine products and allow for the conditional 
approval of such products if safety has been confirmed in clinical trials, even if their efficacy has not been fully demonstrated. The 
legislation creates a new, faster pathway for cell therapy product approval, and offers the potential to enable more rapid entry in the 
Japanese market. The MHLW has been directed to develop and adopt new rules and procedures to implement this legislation.  

These regulatory agencies enforce comprehensive statutes, regulations and guidelines governing the drug development process. This 
process involves several steps. Initially, a company must generate preclinical data to show safety before human testing may be 
initiated. In the United States, a drug company must submit an IND to the FDA prior to securing authorization for human testing. The 
IND must contain adequate data on product candidate chemistry, toxicology and metabolism and, where appropriate, animal research 
testing to support initial safety.  

A Clinical Trial Authorization, or CTA, is the European equivalent of the IND. CTA requirements are issued by each competent 
authority within the European Union and are enacted by local laws and Directives.  

Any of our product candidates will require regulatory approval and compliance with regulations made by United States and foreign 
government agencies prior to commercialization in such countries. The process of obtaining FDA or foreign regulatory agency 
approval has historically been extremely costly and time consuming. The FDA regulates, among other things, the development, 
testing, manufacture, safety, efficacy, record keeping, labeling, storage, approval, advertising, promotion, sale, and distribution of 
biologics and new drugs.  

The standard process required by the FDA before a pharmaceutical agent may be marketed in the United States includes:  

•

•

•

•

•

preclinical tests in animals that demonstrate a reasonable likelihood of safety and effectiveness (if possible) in human 
patients; 

submission to the FDA of an IND, which must become effective before clinical trials in humans can commence. If Phase 1 
clinical trials are to be conducted initially outside the United States, a different regulatory filing is required, depending on 
the location of the trial; 

adequate and well controlled human clinical trials to establish the safety and efficacy of the drug or biologic product for the 
intended disease indication; 

for drugs, submission of a New Drug Application, or NDA, or a Biologic License Application, or BLA, with the FDA; and 

FDA approval of the NDA or BLA before any commercial sale or shipment of the drug. 

18

  
  
  
  
  
  
 
 
 
 
 
Preclinical studies can take several years to complete, and there is no guarantee that an IND based on those studies will become 
effective to permit clinical trials to begin. The clinical development phase generally takes ten to fifteen years, or longer, to complete 
(i.e., from the initiation of Phase 1 through completion of Phase 3 studies), and such sequential studies may overlap or be combined. 
After successful completion of clinical trials for a new drug or biologic product, FDA approval of the NDA or BLA must be obtained. 
This process requires substantial time and effort and there is no assurance that the FDA will accept the NDA or BLA for filing and, 
even if filed, that the FDA will grant approval. In the past, the FDA’s approval of an NDA or BLA has taken, on average, one to two 
years, but in some instances may take substantially longer. If questions regarding safety or efficacy arise, additional studies may be 
required, followed by a resubmission of the NDA or BLA. Review and approval of an NDA or BLA can take up to several years. The 
FDA and other Regulatory agencies such as EMA and PMDA have regulations that allow for faster approval paths and review cycles 
that may reduce clinical development phase completion to between five and seven years to commercialization. Such regulations 
include but are not limited to accelerated/conditional approval paths and review cycles of between six to ten months 
(priority/accelerated review cycles). However, there are specific criteria that must be met to qualify for these paths, such as high 
unmet medical need, orphan designation, fast track, exceptional circumstances and breakthrough designation.  

In addition to obtaining FDA approval for each product, each drug manufacturing facility must be inspected and approved by the 
FDA. All manufacturing establishments are subject to inspections by the FDA and by other federal, state, and local agencies, and 
must comply with good manufacturing practices, or GMP, requirements. We do not currently have any GMP manufacturing 
capabilities, and will rely on contract manufacturers to produce material for any clinical trials that we may conduct.  

We must also obtain regulatory approval in other countries in which we intend to market any drug. The requirements governing 
conduct of clinical trials, product licensing, pricing, and reimbursement vary widely from country to country. FDA approval does not 
ensure regulatory approval in other countries. The current approval process varies from country to country, and the time spent in 
gaining approval varies from that required for FDA approval. In some countries, the sale price of the drug must also be approved. The 
pricing review period often begins after market approval is granted. Even if a foreign regulatory authority approves a drug product, it 
may not approve satisfactory prices for the product.  

In addition to regulations enforced by the FDA and international regulatory agencies, we are also subject to regulation under the 
Occupational Safety and Health Act, the Environmental Protection Act, the Toxic Substances Control Act, the Resource Conservation 
and Recovery Act, and other present and potential future federal, state, or local regulations. Our research and development involves 
the controlled use of hazardous materials, chemicals, biological materials, and various radioactive compounds. Although we believe 
that our safety procedures for handling and disposing of such materials currently comply in all material respects with the standards 
prescribed by state and federal regulations, the risk of accidental contamination or injury from these materials cannot be completely 
eliminated. In the event of such an accident, we could be held liable for any damages that result and any such liability could exceed 
our available resources.  

Employees  

We believe that our success will be based on, among other things, the quality of our clinical programs, our ability to invent and 
develop superior and innovative technologies and products, and our ability to attract and retain capable management and other 
personnel. We have assembled a high quality team of scientists, clinical development managers, and executives with significant 
experience in the biotechnology and pharmaceutical industries.  

As of December 31, 2014, we employed 57 full-time employees, including 18 with Ph.D. degrees. In addition to our employees, we 
also use the service and support of outside consultants and advisors. None of our employees is represented by a union, and we believe 
relationships with our employees are good.

ITEM 1A. RISK FACTORS 

The statements in this section, as well as statements described elsewhere in this annual report, or in other SEC filings, describe risks that 
could materially and adversely affect our business, financial condition and results of operations, which could also cause the trading price of 
our equity securities to decline. These risks are not the only risks that we face. Our business, financial condition and results of operations 
could also be affected by additional factors that are not presently known to us or that we currently consider to be immaterial to our 
operations.  

We have incurred losses since inception and we expect to incur significant net losses in the foreseeable future and may never become 
profitable.  

Since our inception in 1995, we incurred significant losses and negative cash flows from operations. We incurred net losses of $22 million in 
2014, $31 million in 2013 and $15 million in 2012. As of December 31, 2014, we had an accumulated deficit of $287 million and anticipate 
incurring additional losses for at least the next several years. We expect to spend significant resources over the next several years to enhance 
our technologies and to fund research and development of our pipeline of potential products. To date, substantially all of Athersys’ revenue 
has been derived from corporate collaborations, license agreements and government grants. In order to achieve profitability, we must 
develop products and technologies that can be commercialized by us or through our existing or future collaborations. Our ability to generate 
revenues and become profitable will depend on our ability, alone or with potential collaborators, to timely, efficiently and successfully 
complete the development of our product candidates. We have never earned revenue from selling a product and we may never do so, as none 
of our product candidates have been approved for sale, since they are currently being tested in humans and animal studies. We cannot assure 
you that we will ever earn revenue or that we will ever become profitable. If we sustain losses over an extended period of time, we may be 
unable to continue our business.  

We will need substantial additional funding to develop our products and for our future operations. If we are unable to obtain the funds 
necessary to do so, we may be required to delay, scale back or eliminate our product development activities or may be unable to continue 
our business.  

The development of our product candidates will require a commitment of substantial funds to conduct the costly and time-consuming 
research, which may include preclinical and clinical testing, necessary to obtain regulatory approvals and bring our products to market. Net 
cash used in our operations was $26 million in 2014, $23 million in 2013 and $18 million in 2012.  

At December 31, 2014, we had $26 million of cash, cash equivalent and investments, and we will need substantially more to advance our 
product candidates through development. Furthermore, we will need to add additional capital to fund our operations through the completion 
of our current clinical trials. Our future capital requirements will depend on many factors, including:  

•

•

•

•

•

•

•

•

•

•

•

•

•

our ability to raise capital to fund our operations; 

the progress and costs of our research and development programs, including our ability to develop our current portfolio of 
therapeutic products, or discover and develop new ones; 

our ability, or our partners ability and willingness, to advance partnered products or programs, and the speed in which they are 
advanced; 

the cost of prosecuting, defending and enforcing patent claims and other intellectual property rights; 

the progress, scope, costs, and results of our preclinical and clinical testing of any current or future pharmaceutical or MultiStem-
related products; 

the time and cost involved in obtaining regulatory approvals; 

the cost of manufacturing our product candidates; 

expenses related to complying with GMP of therapeutic product candidates; 

costs of financing the purchases of additional capital equipment and development technologies; 

competing technological and market developments; 

our ability to establish and maintain collaborative and other arrangements with third parties to assist in bringing our products to 
market and the cost of such arrangements; 

the amount and timing of payments or equity investments that we receive from collaborators or changes in or terminations of 
future or existing collaboration and licensing arrangements and the timing and amount of expenses we incur to supporting these 
collaborations and license agreements; 

costs associated with the integration of any new operation, including costs relating to future mergers and acquisitions with 
companies that have complementary capabilities; 

20

  
  
  
  
  
  
  
  
  
  
  
  
  
  
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

expenses related to the establishment of sales and marketing capabilities for products awaiting approval or products that 
have been approved; 

the level of our sales and marketing expenses; and 

our ability to introduce and sell new products. 

The extent to which we utilize our existing equity purchase agreement with Aspire Capital Fund, LLC, or Aspire Capital, as a source 
of funding will depend on a number of factors, including the prevailing market price of our common stock, the volume of trading in 
our common stock and the extent to which we are able to secure funds from other sources. The number of shares that we may sell to 
Aspire Capital under the purchase agreement on any given day and during the term of the agreement is limited. Additionally, we and 
Aspire Capital may not effect any sales of shares of our common stock under the purchase agreement during the continuance of an 
event of default. Even if we are able to access the remaining $23.5 million under the purchase agreement as of December 31, 2014, 
we will still need additional capital to fully implement our business, operating and development plans.  

We have secured capital historically from grant revenues, collaboration proceeds, and debt and equity offerings. We will need to 
secure substantial additional capital to fund our future operations. We cannot be certain that additional capital will be available on 
acceptable terms or at all. In recent years, it has been difficult for companies to raise capital due to a variety of factors, which may or 
may not continue. To the extent we raise additional capital through the sale of equity securities, including to Aspire Capital, the 
ownership position of our existing stockholders could be substantially diluted. If additional funds are raised through the issuance of 
preferred stock or debt securities, these securities are likely to have rights, preferences and privileges senior to our common stock. 
Fluctuating interest rates could also increase the costs of any debt financing we may obtain.  

Failure to successfully address ongoing liquidity requirements will have a material adverse effect on our business. If we are unable to 
obtain additional capital on acceptable terms when needed, we may be required to take actions that harm our business and our ability 
to achieve cash flow in the future, including possibly the surrender of our rights to some technologies or product opportunities, 
delaying our clinical trials or curtailing or ceasing operations.  

We are heavily dependent on the successful development and commercialization of MultiStem products, and if we encounter 
delays or difficulties in the development of this product candidate, our business could be harmed.  

Our success is heavily dependent upon the successful development of MultiStem products for certain diseases and conditions 
involving acute or ischemic injury or immune system dysfunction. Our business could be materially harmed if we encounter 
difficulties in the development of this product candidate, such as:  

•

•

•

•

•

delays in the ability to manufacture the product in quantities or in a form that is suitable for any required preclinical studies 
or clinical trials; 

delays in the design, enrollment, implementation or completion of required preclinical studies and clinical trials; 

an inability to follow our current development strategy for obtaining regulatory approval from the FDA because of changes 
in the regulatory approval process; 

less than desired or complete lack of efficacy or safety in preclinical studies or clinical trials; and 

intellectual property constraints that prevent us from making, using, or commercializing the product candidate. 

Our product candidates are in an early stage of development and we currently have no therapeutic products approved for sale. If 
we are unable to develop, obtain regulatory approval or market any of our product candidates, our financial condition will be 
negatively affected, and we may have to curtail or cease our operations.  

Many factors, known and unknown, can adversely affect clinical trials and the ability to evaluate a product’s efficacy. During the 
course of treatment, patients can die or suffer other adverse events for reasons that may or may not be related to the proposed product 
being tested. Even if unrelated to our product, certain events can nevertheless adversely impact our clinical trials. As a result, our 
ability to ultimately develop and market the products and obtain revenues would suffer.  

Even promising results in preclinical studies and initial clinical trials do not ensure successful results in later clinical trials, which test 
broader human use of our products. Many companies in our industry have suffered significant setbacks in advanced clinical trials, 
despite promising results in earlier trials.  

21

  
  
  
  
  
  
  
  
 
 
 
 
 
 
 
 
We are in the early stage of product development, and we are dependent on the application of our technologies to discover or develop 
therapeutic product candidates. We currently do not sell any approved therapeutic products and do not expect to have any products 
commercially available for several years, if at all. You must evaluate us in light of the uncertainties and complexities affecting an 
early stage biotechnology company. Our product candidates require additional research and development, preclinical testing, clinical 
testing and regulatory review and/or approvals or clearances before marketing. To date, no one to our knowledge has commercialized 
any therapeutic products using our technologies and we might never commercialize any product using our technologies and strategy. 
In addition, we may not succeed in developing new product candidates as an alternative to our existing portfolio of product 
candidates. If our current product candidates are delayed or fail, or we fail to successfully develop and commercialize new product 
candidates, our financial condition may be negatively affected, and we may have to curtail or cease our operations.  

We may not successfully maintain our existing collaborative and licensing arrangements, or establish new ones, which could 
adversely affect our ability to develop and commercialize our product candidates.  

A key element of our business strategy is to commercialize some of our product candidates through collaborations with other 
companies. Our strategy includes establishing collaborations and licensing agreements with one or more pharmaceutical, 
biotechnology or device companies, preferably after we have advanced product candidates through the initial stages of clinical 
development. However, we may not be able to establish or maintain such licensing and collaboration arrangements necessary to 
develop and commercialize our product candidates. Even if we are able to maintain or establish licensing or collaboration 
arrangements, these arrangements may not be on favorable terms and may contain provisions that will restrict our ability to develop, 
test and market our product candidates. Any failure to maintain or establish licensing or collaboration arrangements on favorable 
terms could adversely affect our business prospects, financial condition or ability to develop and commercialize our product 
candidates.  

Our agreements with our collaborators and licensees may have provisions that give rise to disputes regarding the rights and 
obligations of the parties. These and other possible disagreements could lead to termination of the agreement or delays in 
collaborative research, development, supply, or commercialization of certain product candidates, or could require or result in 
litigation or arbitration. Moreover, disagreements could arise with our collaborators over rights to intellectual property or our rights to 
share in any of the future revenues of products developed by our collaborators. These kinds of disagreements could result in costly 
and time-consuming litigation. Any such conflicts with our collaborators could reduce our ability to obtain future collaboration 
agreements and could have a negative impact on our relationship with existing collaborators.  

Currently, our material collaborations and licensing arrangements are our collaborations with (a) Chugai to develop and 
commercialize MultiStem cell therapy for the treatment of ischemic stroke in Japan, (b) Pfizer to develop and commercialize 
MultiStem for the treatment of IBD and (c) RTI to develop and commercialize MAPC technology-based biologic implants for certain 
orthopedic applications in the bone graft substitutes market, and our license with the University of Minnesota pursuant to which we 
license certain aspects of the MAPC technology. These arrangements do not have specific termination dates; rather, each arrangement 
terminates upon the occurrence of certain events.  

If our collaborators do not devote sufficient time and resources to successfully carry out their contracted duties or meet expected 
deadlines, we may not be able to advance our product candidates in a timely manner or at all.  

Our success depends on the performance by our collaborators of their responsibilities under our collaboration arrangements. Some 
potential collaborators may not perform their obligations in a timely fashion or in a manner satisfactory to us. Typically, we cannot 
control the amount of resources or time our collaborators may devote to our programs or potential products that may be developed in 
collaboration with us. We are currently involved in multiple research and development collaborations with academic and research 
institutions. These collaborators frequently depend on outside sources of funding to conduct or complete research and development, 
such as grants or other awards. In addition, our academic collaborators may depend on graduate students, medical students, or 
research assistants to conduct certain work, and such individuals may not be fully trained or experienced in certain areas, or they may 
elect to discontinue their participation in a particular research program, creating an inability to complete ongoing research in a timely 
and efficient manner. As a result of these uncertainties, we are unable to control the precise timing and execution of any experiments 
that may be conducted.  

Additionally, our current or future corporate collaborators will retain the ability to pursue other research, product development or 
commercial opportunities that may be directly competitive with our programs. If these collaborators elect to prioritize or pursue other 
programs in lieu of ours, we may not be able to advance product development programs in an efficient or effective manner, if at all. If 
a collaborator is pursuing a competitive program and encounters unexpected financial or capability limitations, they may be motivated 
to reduce the priority placed on our programs or delay certain activities related to our programs or be unwilling to properly fund their 
share of the development expenses for our programs. Any of these developments could harm our product and technology 
development efforts, which could seriously harm our business.  

22

  
We may experience delays in clinical trials and regulatory approval relating to our products that could adversely affect our 
financial results and our commercial prospects for our pharmaceutical or stem cell products.  

In addition to the regulatory requirements for our pharmaceutical programs, we will also require regulatory approvals for each distinct 
application of our stem cell product. In each case, we will be required to conduct clinical trials to demonstrate safety and efficacy of 
MultiStem, or various products that incorporate or use MultiStem. For product candidates that advance to clinical testing, we cannot 
be certain that we or a collaborator will successfully complete the clinical trials necessary to receive regulatory product approvals. 
This process is lengthy and expensive.  

We intend to seek approval for our product candidates through the FDA approval process. To obtain regulatory approvals, we must, 
among other requirements, complete clinical trials showing that our products are safe and effective for a particular indication. Under 
the approval process, we must submit clinical and non-clinical data to demonstrate the medication is safe and effective. For example, 
we must be able to provide data and information, which may include extended pharmacology, toxicology, reproductive toxicology, 
bioavailability and genotoxicity studies, to establish suitability for Phase 2 or large scale Phase 3 clinical trials.  

All of our product candidates are at an early stage of development. As these programs enter and progress through early stage clinical 
development, or complete additional non-clinical testing, an indication of a lack of safety or lack of efficacy may result in the early 
termination of an ongoing trial, or may cause us or any of our collaborators to forego further development of a particular product 
candidate or program. The FDA or other regulatory agencies may require extensive clinical trials or other testing prior to granting 
approval, which could be costly and time consuming to conduct. Any of these developments would hinder, and potentially prohibit, 
our ability to commercialize our product candidates. We cannot assure you that clinical trials will in fact demonstrate that our 
products are safe or effective.  

Additionally, we may not be able to find acceptable patients or may experience delays in enrolling patients for our currently planned 
or any future clinical trials. The FDA or we may suspend our clinical trials at any time if either believes that we are exposing the 
subjects participating in the trials to unacceptable health risks. The FDA or institutional review boards and/or institutional biosafety 
committees at the medical institutions and healthcare facilities where we seek to sponsor clinical trials may not permit a trial to 
proceed or may suspend any trial indefinitely if they find deficiencies in the conduct of the trials.  

Product development costs to us and our potential collaborators will increase if we have delays in testing or approvals or if we need to 
perform more or larger clinical trials than planned. We expect to continue to rely on third-party clinical investigators at medical 
institutions and healthcare facilities to conduct our clinical trials, and, as a result, we may face additional delaying factors outside our 
control. Significant delays may adversely affect our financial results and the commercial prospects for our product candidates and 
delay our ability to become profitable.  

The results seen in animal testing of our product candidates may not be replicated in humans.  

This annual report discusses the safety and efficacy seen in preclinical testing of our lead product candidates, including MultiStem, in 
animals, but we may not see positive results when our other product candidates undergo clinical testing in humans in the future. 
Preclinical studies and Phase 1 clinical trials are not primarily designed to test the efficacy of a product candidate in humans, but 
rather to:  

•

•

•

•

test short-term safety and tolerability; 

study the absorption, distribution, metabolism and elimination of the product candidate; 

study the biochemical and physiological effects of the product candidate and the mechanisms of the drug action and the 
relationship between drug levels and effect; and 

understand the product candidate’s side effects at various doses and schedules. 

Success in preclinical studies or completed clinical trials does not ensure that later studies or trials, including continuing non-clinical 
studies and large-scale clinical trials, will be successful nor does it necessarily predict future results. The rate of failure in drug 
development is quite high, and many companies in the biotechnology and pharmaceutical industries have suffered significant setbacks 
in advanced clinical trials, even after promising results in earlier trials. Product candidates may fail to show desired safety and 
efficacy in larger and more diverse patient populations in later stage clinical trials, despite having progressed through early stage 
trials. Negative or inconclusive results from any of our ongoing preclinical studies or clinical trials could result in delays, 
modifications, or abandonment of ongoing or future clinical trials and the termination of our development of a product candidate. 
Additionally, even if we are able to successfully complete pivotal Phase 3 clinical trials, the FDA still may not approve our product 
candidates.  

23

  
  
  
  
  
 
 
 
 
Even if we obtain regulatory approval of any of our product candidates, the approved products may be subject to post-approval 
studies and will remain subject to ongoing regulatory requirements. If we fail to comply, or if concerns are identified in 
subsequent studies, our approval could be withdrawn and our product sales could be suspended.  

If we are successful at obtaining regulatory approval for MultiStem or any of our other product candidates, regulatory agencies in the 
United States and other countries where a product will be sold may require extensive additional clinical trials or post-approval clinical 
studies that are expensive and time consuming to conduct. In particular, therapeutic products administered for the treatment of 
persistent or chronic conditions, such as obesity, are likely to require extensive follow-up studies and close monitoring of patients 
after regulatory approval has been granted, for any signs of adverse effects that occur over a long period of time. These studies may 
be expensive and time consuming to conduct and may reveal side effects or other harmful effects in patients that use our therapeutic 
products after they are on the market, which may result in the limitation or withdrawal of our drugs from the market. Alternatively, 
we may not be able to conduct such additional trials, which might force us to abandon our efforts to develop or commercialize certain 
product candidates. Even if post-approval studies are not requested or required, after our products are approved and on the market, 
there might be safety issues that emerge over time that require a change in product labeling or that require withdrawal of the product 
from the market, which would cause our revenue to decline.  

Additionally, any products that we may successfully develop will be subject to ongoing regulatory requirements after they are 
approved. These requirements will govern the manufacturing, packaging, marketing, distribution, and use of our products. If we fail 
to comply with such regulatory requirements, approval for our products may be withdrawn, and product sales may be suspended. We 
may not be able to regain compliance, or we may only be able to regain compliance after a lengthy delay, significant expense, lost 
revenues and damage to our reputation.  

We may rely on third parties to manufacture our MultiStem product candidate.  

Our current business strategy relies on third parties to manufacture our MultiStem product candidates in accordance with good 
manufacturing practices established by the FDA, or similar regulations in other countries. These third parties may not deliver 
sufficient quantities of our MultiStem product candidates, manufacture MultiStem product candidates in accordance with 
specifications, or comply with applicable government regulations. Additionally, if the manufactured products fail to perform as 
specified, our business and reputation could be severely impacted.  

We expect to enter into additional manufacturing agreements for the production of product materials. If any manufacturing agreement 
is terminated or any third party collaborator experiences a significant problem that could result in a delay or interruption in the supply 
of product materials to us, there are very few contract manufacturers that currently have the capability to produce our MultiStem 
product on acceptable terms, or on a timely and cost-effective basis. We cannot assure you that manufacturers on whom we will 
depend will be able to successfully produce our MultiStem product on acceptable terms, or on a timely or cost-effective basis. We 
cannot assure you that manufacturers will be able to manufacture our products in accordance with our product specifications or will 
meet FDA or other requirements. We must have sufficient and acceptable quantities of our product materials to conduct our clinical 
trials and ultimately to market our product candidates, if and when such products have been approved by the FDA for marketing. If 
we are unable to obtain sufficient and acceptable quantities of our product material, we may be required to delay the clinical testing 
and marketing of our products.  

If we do not comply with applicable regulatory requirements in the manufacture and distribution of our product candidates, we 
may incur penalties that may inhibit our ability to commercialize our products and adversely affect our revenue.  

Our failure or the failure of our potential collaborators or third party manufacturers to comply with applicable FDA or other 
regulatory requirements including manufacturing, quality control, labeling, safety surveillance, promoting and reporting may result in 
criminal prosecution, civil penalties, recall or seizure of our products, total or partial suspension of production or an injunction, as 
well as other regulatory action against our product candidates or us. Discovery of previously unknown problems with a product, 
supplier, manufacturer or facility may result in restrictions on the sale of our products, including a withdrawal of such products from 
the market. The occurrence of any of these events would negatively impact our business and results of operations.  

If we are unable to attract and retain key personnel and advisors, it may adversely affect our ability to obtain financing, pursue 
collaborations or develop our product candidates.  

We are highly dependent on our executive officers Gil Van Bokkelen, Ph.D., our Chief Executive Officer, William Lehmann, J.D., 
M.B.A., President and Chief Operating Officer, John Harrington, Ph.D., Chief Scientific Officer and Executive Vice President, 
Robert Deans, Ph.D., Executive Vice President, Regenerative Medicine, and Laura Campbell, CPA, Vice President of Finance, as 
well as other personnel.

These individuals are integral to the development and integration of our technologies and to our present and future scientific 
collaborations, including managing the complex research processes and the product development and potential commercialization 
processes. Given their leadership, extensive technical, scientific and financial expertise and management and operational experience, 
these individuals would be difficult to replace. Consequently, the loss of services of one or more of these named individuals could result 
in product development delays or the failure of our collaborations with current and future collaborators, which, in turn, may hurt our 
ability to develop and commercialize products and generate revenues.  

Our future success depends on our ability to attract, retain and motivate highly qualified management and scientific, development and 
commercial personnel and advisors. If we are unable to attract and retain key personnel and advisors, it may negatively affect our ability 
to successfully develop, test and commercialize our product candidates.  

Our ability to compete may decline if we are not successful in adequately protecting our patented and other proprietary technologies. 

Our success depends in part on our ability to obtain and maintain intellectual property that protects our technologies and our products. 
Patent positions may be highly uncertain and may involve complex legal and factual questions, including the ability to establish 
patentability of compounds and methods for using them for which we seek patent protection. We cannot predict the breadth of claims 
that will ultimately be allowed in our patent applications, if any, including those we have in-licensed or the extent to which we may 
enforce these claims against our competitors. We filed multiple patent applications that seek to protect the composition of matter and 
method of use related to our programs. In addition, we are prosecuting numerous distinct patent families directed to composition, 
methods of production, and methods of use of MultiStem and related technologies. If we are unsuccessful in obtaining and maintaining 
these patents related to products and technologies, we may ultimately be unable to commercialize products that we are developing or 
may elect to develop in the future.  

The degree of future protection for our proprietary rights is therefore highly uncertain and we cannot assure you that:  

•

•

•

•

•

•

•

•

•

we were the first to file patent applications or to invent the subject matter claimed in patent applications relating to the 
technologies or product candidates upon which we rely; 

others will not independently develop similar or alternative technologies or duplicate any of our technologies; 

others did not publicly disclose our claimed technology before we conceived the subject matter included in any of our patent 
applications; 

any of our pending or future patent applications will result in issued patents; 

any of our patent applications will not result in interferences or disputes with third parties regarding priority of invention; 

any patents that may be issued to us, our collaborators or our licensors will provide a basis for commercially viable products 
or will provide us with any competitive advantages or will not be challenged by third parties; 

we will develop additional proprietary technologies that are patentable; 

the patents of others will not have an adverse effect on our ability to do business; or 

new proprietary technologies from third parties, including existing licensors, will be available for licensing to us on 
reasonable commercial terms, if at all. 

In addition, patent law outside the United States is uncertain and in many countries intellectual property laws are undergoing review and 
revision. The laws of some countries do not protect intellectual property rights to the same extent as domestic laws. It may be necessary 
or useful for us to participate in opposition proceedings to determine the validity of our competitors’ patents or to defend the validity of 
any of our or our licensor’s future patents, which could result in substantial costs and would divert our efforts and attention from other 
aspects of our business. With respect to certain of our inventions, we decided not to pursue patent protection outside the United States, 
both because we do not believe it is cost effective and because of confidentiality concerns. Accordingly, our international competitors 
could develop and receive foreign patent protection for gene sequences and functions for which we are seeking United States patent 
protection, enabling them to sell products that we developed.  

Technologies licensed to us by others, or in-licensed technologies, are important to our business. The scope of our rights under our 
licenses may be subject to dispute by our licensors or third parties. Our rights to use these technologies and to practice the inventions 
claimed in the licensed patents are subject to our licensors abiding by the terms of those licenses and not terminating them. In particular, 
we depend on certain technologies relating to our MultiStem technology licensed from the University of Minnesota, and the termination 
of this license could result in our loss of some of the rights that enable us to utilize this technology, and our ability to develop products 
based on MultiStem could be seriously hampered.  

25

  
  
  
  
  
  
  
  
  
  
 
 
 
 
 
 
 
 
 
In addition, we may in the future acquire rights to additional technologies by licensing such rights from existing licensors or from 
third parties. Such in-licenses may be costly. Also, we generally do not control the patent prosecution, maintenance or enforcement of 
in-licensed technologies. Accordingly, we are unable to exercise the same degree of control over this intellectual property as we do 
over our internally developed technologies. Moreover, some of our academic institution licensors, collaborators and scientific 
advisors have rights to publish data and information to which we have rights. If we cannot maintain the confidentiality of our 
technologies and other confidential information in connection with our collaborations, our ability to protect our proprietary 
information or obtain patent protection in the future may be impaired, which could have a significant adverse effect on our business, 
financial condition and results of operations.  

We may not have adequate protection for our unpatented proprietary information, which could adversely affect our competitive 
position.  

In addition to patents, we will substantially rely on trade secrets, know-how, continuing technological innovations and licensing 
opportunities to develop and maintain our competitive position. However, others may independently develop substantially equivalent 
proprietary information and techniques or otherwise gain access to our trade secrets or disclose our technology. To protect our trade 
secrets, we may enter into confidentiality agreements with employees, consultants and potential collaborators. However, these 
agreements may not provide meaningful protection of our trade secrets or adequate remedies in the event of unauthorized use or 
disclosure of such information. Likewise, our trade secrets or know-how may become known through other means or be 
independently discovered by our competitors. Any of these events could prevent us from developing or commercializing our product 
candidates.  

We may be sued for product liability, which could adversely affect our business.  

Because our business strategy involves the development and sale by either us or our collaborators of commercial products, we may be 
sued for product liability. We may be held liable if any product we develop and commercialize, or any product our collaborators 
commercialize that incorporates any of our technology, causes injury or is found otherwise unsuitable during product testing, 
manufacturing, marketing, sale or consumer use. In addition, the safety studies we must perform and the regulatory approvals 
required to commercialize our pharmaceutical products, will not protect us from any such liability.  

We carry product liability insurance that includes coverage for human clinical trials. Currently, we carry a $5 million per event, $5 
million annual aggregate coverage for both our products liability policy and our clinical trials protection. We also intend to seek 
product liability insurance for any approved products that we may develop or acquire. However, in the event there are product 
liability claims against us, our insurance may be insufficient to cover the expense of defending against such claims, or may be 
insufficient to pay or settle such claims. Furthermore, we may be unable to obtain adequate product liability insurance coverage for 
commercial sales of any of our approved products. If such insurance is insufficient to protect us, our results of operations will suffer. 
If any product liability claim is made against us, our reputation and future sales will be damaged, even if we have adequate insurance 
coverage.  

Many potential competitors, including those who have greater resources and experience than we do, may develop products or 
technologies that make ours obsolete or noncompetitive.  

We face significant competition with respect to our product candidates. With regard to our efforts to develop MultiStem as a novel 
stem cell therapy, currently, there are a number of companies that are actively developing stem cell products, which encompass a 
range of different cell types, including embryonic stem cells, adult-derived stem cells, and processed bone marrow derived cells. Our 
future success will depend on our ability to maintain a competitive position with respect to technological advances. Technological 
developments by others may result in our MultiStem product platform and technologies, as well as our pharmaceutical formulations, 
becoming obsolete.  

We are subject to significant competition from pharmaceutical, biotechnology and diagnostic companies, academic and research 
institutions, and government or other publicly funded agencies that are pursuing or may pursue the development of therapeutic 
products and technologies that are substantially similar to our proposed therapeutic products and technologies, or that otherwise 
address the indications we are pursuing. Our most significant competitors include major pharmaceutical companies such as Pfizer, 
Roche, Johnson & Johnson, Sanofi and GlaxoSmithKline, as well as smaller biotechnology or biopharmaceutical companies such as 
Celgene, Mesoblast, Aastrom, Stem Cells Inc., Cytori, Pluristem, Arena Pharmaceuticals and Vivus. Most of our current and potential 
competitors have substantially greater research and development capabilities and financial, scientific, regulatory, manufacturing, 
marketing, sales, human resources, and experience than we do. Many of our competitors have several therapeutic products that have 
already been developed, approved and successfully commercialized, or are in the process of obtaining regulatory approval for their 
therapeutic products in the United States and internationally.  

26

  
Many of these companies have substantially greater capital resources, research and development resources and experience, manufacturing 
capabilities, regulatory expertise, sales and marketing resources, established relationships with consumer products companies and production 
facilities.  

Universities and public and private research institutions are also potential competitors. While these organizations primarily have educational 
objectives, they may develop proprietary technologies related to stem cells or secure patent protection that we may need for the development 
of our technologies and products. We may attempt to license these proprietary technologies, but these licenses may not be available to us on 
acceptable terms, if at all. Our competitors, either alone or with their collaborative partners, may succeed in developing technologies or 
products that are more effective, safer, more affordable or more easily commercialized than ours, and our competitors may obtain intellectual 
property protection or commercialize products sooner than we do. Developments by others may render our product candidates or our 
technologies obsolete.  

Our current product discovery and development collaborators are not prohibited from entering into research and development collaboration 
agreements with third parties in any product field. Our failure to compete effectively would have a significant adverse effect on our business, 
financial condition and results of operations.  

The availability, manner, and amount of reimbursement for our product candidates from government and private payers are uncertain, 
and our inability to obtain adequate reimbursement for any products could severely limit our product sales.  

We expect that many of the patients who seek treatment with any of our products that are approved for marketing will be eligible for 
Medicare benefits. Other patients may be covered by private health plans. If we are unable to obtain or retain adequate levels of 
reimbursement from Medicare or from private health plans, our ability to sell our products will be severely limited. The application of 
existing Medicare regulations and interpretive coverage and payment determinations to newly approved products is uncertain and those 
regulations and interpretive determinations are subject to change. The Medicare Prescription Drug Improvement and Modernization Act, 
enacted in December 2003, provides for a change in reimbursement methodology that reduces the Medicare reimbursement rates for many 
drugs, which may adversely affect reimbursement for any products we may develop. Medicare regulations and interpretive determinations 
also may determine who may be reimbursed for certain services, and may limit the pool of patients our product candidates are being 
developed to serve.  

Federal, state and foreign governments continue to propose legislation designed to contain or reduce health care costs. Legislation and 
regulations affecting the pricing of products like our potential products may change further or be adopted before any of our potential 
products are approved for marketing. Cost control initiatives by governments or third-party payers could decrease the price that we receive 
for any one or all of our potential products or increase patient coinsurance to a level that make our products under development become 
unaffordable. In addition, government and private health plans persistently challenge the price and cost-effectiveness of therapeutic products. 
Accordingly, these third parties may ultimately not consider any or all of our products under development to be cost effective, which could 
result in products not being covered under their health plans or covered only at a lower price. Any of these initiatives or developments could 
prevent us from successfully marketing and selling any of our products that are approved for commercialization.  

Public perception of ethical and social issues surrounding the use of adult-derived stem cell technology may limit or discourage the use 
of our technologies, which may reduce the demand for our therapeutic products and technologies and reduce our revenues.  

Our success will depend in part upon our ability to develop therapeutic products incorporating or discovered through our adult-derived stem 
cell technology. For social, ethical, or other reasons, governmental authorities in the United States and other countries may call for limits on, 
or regulation of the use of, adult-derived stem cell technologies. Although we do not use the more controversial stem cells derived from 
embryos or fetuses, claims that adult-derived stem cell technologies are ineffective, unethical or pose a danger to the environment may 
influence public attitudes. The subject of stem cell technologies in general has received negative publicity and aroused public debate in the 
United States and some other countries. Ethical and other concerns about our adult-derived stem cell technology could materially hurt the 
market acceptance of our therapeutic products and technologies, resulting in diminished sales and use of any products we are able to develop 
using adult-derived stem cells.  

Even if we or our collaborators receive regulatory approval for our products, those products may never be commercially successful.  

Even if we develop pharmaceuticals or MultiStem related products that obtain the necessary regulatory approval, and we have access to the 
necessary manufacturing, sales, marketing and distribution capabilities that we need, our success depends to a significant degree upon the 
commercial success of those products. If these products fail to achieve or subsequently maintain market acceptance or commercial viability, 
our business would be significantly harmed because our future royalty revenue or other revenue would be dependent upon sales of these 
products. Many factors may affect the market acceptance and commercial success of any potential products that we may discover, including: 

27

  
•

•

•

•

•

•

•

•

•

•

•

health concerns, whether actual or perceived, or unfavorable publicity regarding our obesity drugs, stem cell products or 
those of our competitors; 

the timing of market entry as compared to competitive products; 

the rate of adoption of products by our collaborators and other companies in the industry; 

any product labeling that may be required by the FDA or other United States or foreign regulatory agencies for our 
products or competing or comparable products; 

convenience and ease of administration; 

pricing; 

perceived efficacy and side effects; 

marketing; 

availability of alternative treatments; 

levels of reimbursement and insurance coverage; and 

activities by our competitors. 

If we are unable to create and maintain sales, marketing and distribution capabilities or enter into agreements with third parties to 
perform those functions, we will not be able to commercialize our product candidates.  

We currently have no sales, marketing or distribution capabilities. Therefore, to commercialize our product candidates, if and when 
such products have been approved and are ready for marketing, we expect to collaborate with third parties to perform these functions. 
We will either need to share the value generated from the sale of any products and/or pay a fee to the contract sales organization. If 
we establish any such relationships, we will be dependent upon the capabilities of our collaborators or contract service providers to 
effectively market, sell, and distribute our product. If they are ineffective at selling and distributing our product, or if they choose to 
emphasize other products over ours, we may not achieve the level of product sales revenues that we would like. If conflicts arise, we 
may not be able to resolve them easily or effectively, and we may suffer financially as a result. If we cannot rely on the sales, 
marketing and distribution capabilities of our collaborators or of contract service providers, we may be forced to establish our own 
capabilities. We have no experience in developing, training or managing a sales force and will incur substantial additional expenses if 
we decide to market any of our future products directly. Developing a marketing and sales force is also time consuming and could 
delay launch of our future products. In addition, we will compete with many companies that currently have extensive and well-funded 
marketing and sales operations. Our marketing and sales efforts may be unable to compete successfully against these companies.  

We will use hazardous and biological materials in our business. Any claims relating to improper handling, storage or disposal of 
these materials could be time consuming and costly.  

Our products and processes will involve the controlled storage, use and disposal of certain hazardous and biological materials and 
waste products. We and our suppliers and other collaborators are subject to federal, state and local regulations governing the use, 
manufacture, storage, handling and disposal of materials and waste products. Even if we and these suppliers and collaborators comply 
with the standards prescribed by law and regulation, the risk of accidental contamination or injury from hazardous materials cannot be 
completely eliminated. In the event of an accident, we could be held liable for any damages that result, and any liability could exceed 
the limits or fall outside the coverage of any insurance we may obtain and exceed our financial resources. We may not be able to 
maintain insurance on acceptable terms, or at all. We may incur significant costs to comply with current or future environmental laws 
and regulations.  

Disputes concerning the infringement or misappropriation of our proprietary rights or the proprietary rights of others could be 
time consuming and extremely costly and could delay our research and development efforts.  

Our commercial success, if any, will be significantly harmed if we infringe the patent rights of third parties or if we breach any 
license or other agreements that we entered into with regard to our technology or business.  

28

  
  
  
  
  
  
  
  
  
  
  
 
 
 
 
 
 
 
 
 
 
 
We are aware of other companies and academic institutions that have been performing research in the areas of adult derived stem 
cells. In particular, other companies and academic institutions have announced that they have identified nonembryonic stem cells 
isolated from bone marrow or other tissues that have the ability to form a range of cell types, or display the property of pluripotency. 
To the extent any of these companies or academic institutions currently have, or obtain in the future, broad patent claims, such patents 
could block our ability to use various aspects of our discovery and development process and might prevent us from developing or 
commercializing newly discovered applications of our MultiStem technology, or otherwise conducting our business. In addition, it is 
possible that some of the pharmaceutical product candidates we are developing may not be patentable or may be covered by 
intellectual property of third parties.  

We are not currently a party to any litigation with regard to our patent or trademark positions. However, the life sciences and other 
technology industries are characterized by extensive litigation regarding patents and other intellectual property rights. Many life 
sciences and other technology companies have employed intellectual property litigation as a way to gain a competitive advantage. To 
the extent we are involved in litigation, interference proceedings, oppositions, reexamination, protest or other potentially adverse 
intellectual property proceedings as a result of alleged infringement by us of the rights of others or as a result of priority of invention 
disputes with third parties, we might have to spend significant amounts of money, time and effort defending our position and we may 
not be successful. In addition, any claims relating to the infringement of third-party proprietary rights or proprietary determinations, 
even if not meritorious, could result in costly litigation, lengthy governmental proceedings, divert management’s attention and 
resources, or require us to enter into royalty or license agreements that are not advantageous to us. If we do not have the financial 
resources to support such litigation or appeals, we may forfeit or lose certain commercial rights. Even if we have the financial 
resources to continue such litigation or appeals, we may lose. In the event that we lose, we may be forced to pay very substantial 
damages; we may have to obtain costly license rights, which may not be available to us on acceptable terms, if at all; or we may be 
prohibited from selling products that are found to infringe the patent rights of others.  

Should any person have filed patent applications or obtained patents that claim inventions also claimed by us, we may have to 
participate in an interference proceeding declared by the relevant patent regulatory agency to determine priority of invention and, 
thus, the right to a patent for these inventions in the United States. Such a proceeding could result in substantial cost to us even if the 
outcome is favorable. Even if successful on priority grounds, an interference action may result in loss of claims based on patentability 
grounds raised in the interference action. Litigation, interference proceedings or other proceedings could divert management’s time 
and efforts. Even unsuccessful claims could result in significant legal fees and other expenses, diversion of management’s time and 
disruption in our business. Uncertainties resulting from initiation and continuation of any patent proceeding or related litigation could 
harm our ability to compete and could have a significant adverse effect on our business, financial condition and results of operations.  

An adverse ruling arising out of any intellectual property dispute, including an adverse decision as to the priority of our inventions, 
could undercut or invalidate our intellectual property position. An adverse ruling could also subject us to significant liability for 
damages, including possible treble damages, prevent us from using technologies or developing products, or require us to negotiate 
licenses to disputed rights from third parties. Although patent and intellectual property disputes in the technology area are often 
settled through licensing or similar arrangements, costs associated with these arrangements may be substantial and could include 
license fees and ongoing royalties. Furthermore, necessary licenses may not be available to us on satisfactory terms, if at all. Failure 
to obtain a license in such a case could have a significant adverse effect on our business, financial condition and results of operations. 

To the extent we enter markets outside of the United States, our business will be subject to political, economic, legal and social 
risks in those markets, which could adversely affect our business.  

There are significant regulatory and legal barriers in markets outside the United States that we must overcome to the extent we enter 
or attempt to enter markets in countries other than the United States. We will be subject to the burden of complying with a wide 
variety of national and local laws, including multiple and possibly overlapping and conflicting laws. We also may experience 
difficulties adapting to new cultures, business customs and legal systems. Any sales and operations outside the United States would 
be subject to political, economic and social uncertainties including, among others:  

•

•

•

•

•

•

changes and limits in import and export controls; 

increases in custom duties and tariffs; 

changes in currency exchange rates; 

economic and political instability; 

changes in government regulations and laws; 

absence in some jurisdictions of effective laws to protect our intellectual property rights; and 

29

  
  
  
  
  
  
  
 
 
 
 
 
 
•

currency transfer and other restrictions and regulations that may limit our ability to sell certain products or repatriate profits to 
the United States. 

Any changes related to these and other factors could adversely affect our business to the extent we enter markets outside the United 
States.  

Foreign governments often impose strict price controls on approved products, which may adversely affect our future profitability in 
those countries, and the re-importation of drugs to the United States from foreign countries that impose price controls may adversely 
affect our future profitability.  

Frequently foreign governments impose strict price controls on newly approved therapeutic products. If we obtain regulatory approval to 
sell products in foreign countries, we may be unable to obtain a price that provides an adequate financial return on our investment. 
Furthermore, legislation in the United States may permit re-importation of drugs from foreign countries into the United States, including 
re-importation from foreign countries where the drugs are sold at lower prices than in the United States due to foreign government-
mandated price controls. Such a practice, especially if it is conducted on a widespread basis, may significantly reduce our potential 
United States revenues from any drugs that we are able to develop.  

If we elect not to sell our products in foreign countries that impose government mandated price controls because we decide it is 
uneconomical to do so, a foreign government or patent office may attempt to terminate our intellectual property rights in that 
country, enabling competitors to make and sell our products.  

In some cases we may choose not to sell a product in a foreign country because it is uneconomical to do so under a system of 
government-imposed price controls, or because it could severely limit our profitability in the United States or other markets. In such 
cases, a foreign government or patent office may terminate any intellectual property rights we may obtain with respect to that product. 
Such a termination could enable competitors to produce and sell our product in that market. Furthermore, such products may be exported 
into the United States through legislation that authorizes the importation of drugs from outside the United States. In such an event, we 
may have to reduce our prices, or we may be unable to compete with low-cost providers of our drugs, and we could be financially 
harmed as a result.  

We may encounter difficulties managing our growth, which could adversely affect our business.  

At various times we have experienced periods of rapid growth in our employee numbers as a result of a dramatic increase in activity in 
technology programs, genomics programs, collaborative research programs, discovery programs, and scope of operations. At other 
times, we had to reduce staff in order to bring our expenses in line with our financial resources. Our success will also depend on the 
ability of our officers and key employees to continue to improve our operational capabilities and our management information and 
financial control systems, and to expand, train and manage our work force.  

If we acquire products, technologies or other businesses, we will incur a variety of costs, may have integration difficulties and may 
experience numerous other risks that could adversely affect our business.  

To remain competitive, we may decide to acquire additional businesses, products and technologies. We currently have no commitments 
or agreements with respect to, and are not actively seeking, any material acquisitions. We have limited experience in identifying 
acquisition targets, successfully acquiring them and integrating them into our current infrastructure. We may not be able to successfully 
integrate any businesses, products, technologies or personnel that we might acquire in the future without a significant expenditure of 
operating, financial and management resources, if at all. In addition, future acquisitions could require significant capital infusions and 
could involve many risks, including, but not limited to the following:  

•

•

•

•

•

we may have to issue convertible debt or equity securities to complete an acquisition, which would dilute our stockholders 
and could adversely affect the market price of our common stock; 

an acquisition may negatively impact our results of operations because it may require us to incur large one-time charges to 
earnings, amortize or write down amounts related to goodwill and other intangible assets, or incur or assume substantial debt 
or liabilities, or it may cause adverse tax consequences, substantial depreciation or deferred compensation charges; 

we may encounter difficulties in assimilating and integrating the business, technologies, products, personnel or operations of 
companies that we acquire; 

certain acquisitions may disrupt our relationship with existing collaborators who are competitive to the acquired business; 

acquisitions may require significant capital infusions and the acquired businesses, products or technologies may not generate 
sufficient revenue to offset acquisition costs; 

30

  
  
  
  
  
  
 
 
 
 
 
 
•

•

•

an acquisition may disrupt our ongoing business, divert resources, increase our expenses and distract our management; 

acquisitions may involve the entry into a geographic or business market in which we have little or no prior experience; and 

key personnel of an acquired company may decide not to work for us. 

Any of the foregoing risks could have a significant adverse effect on our business, financial condition and results of operations.  

Increased information technology security threats and more sophisticated and targeted computer crime could pose a risk to our 
systems, networks, and products.  

Increased global information technology security threats and more sophisticated and targeted computer crime pose a risk to the 
security of our systems and networks and the confidentiality, availability and integrity of our data and communications. While we 
attempt to mitigate these risks by employing a number of measures, including employee refreshers, monitoring of our networks and 
systems, and maintenance of backup and protective systems, our systems, networks and products remain potentially vulnerable to 
advanced persistent threats. Depending on their nature and scope, such threats could potentially lead to the compromising of 
confidential information and communications, improper use of our systems and networks, manipulation and destruction of data, 
defective products, production downtimes and operational disruptions, which in turn could adversely affect our reputation, 
competitiveness and results of operations.  

If we do not continue to meet the listing standards established by The NASDAQ Capital Market, the common stock may not 
remain listed for trading.  

The NASDAQ Capital Market has established certain quantitative criteria and qualitative standards that companies must meet in 
order to remain listed for trading on these markets. We cannot guarantee that we will be able to maintain all necessary requirements 
for listing; therefore, we cannot guarantee that our common stock will remain listed for trading on The NASDAQ Capital Market or 
other similar markets.

Holders  

As of March 5, 2015, there were approximately 540 holders of record of our common stock. Additionally, shares of common stock 
are held by financial institutions as nominees for beneficial owners that are deposited into participant accounts at the Depository Trust 
Company, which are considered to be held of record by Cede & Co. and are included in the holders of record as one stockholder.  

Dividend Policy  

We would have to rely upon dividends and other payments from our wholly owned subsidiary, ABT Holding Company, to generate 
the funds necessary to make dividend payments, if any, on our common stock. ABT Holding Company, however, is legally distinct 
from us and has no obligation to pay amounts to us. The ability of ABT Holding Company to make dividend and other payments to us 
is subject to, among other things, the availability of funds and applicable state laws. However, there are no restrictions such as 
government regulations or material contractual arrangements that restrict the ability of ABT Holding Company to make dividend and 
other payments to us. We did not pay cash dividends on our common stock during the past three years. We do not anticipate that we 
will pay any dividends on our common stock in the foreseeable future. Rather, we anticipate that we will retain earnings, if any, for 
use in the development of our business.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 

OPERATIONS 

You should read the following discussion and analysis in conjunction with “Item 8. Financial Statements and Supplementary Data” 
included below in this annual report on Form 10-K.  

Overview  

We are an international biotechnology company that is focused primarily in the field of regenerative medicine. Our MultiStem® cell 
therapy is currently being evaluated in multiple clinical trials. Our current clinical development programs are focused on treating 
inflammatory and immune disorders, neurological conditions, cardiovascular disease, and other conditions. We are also applying our 
pharmaceutical discovery capabilities to identify and develop small molecule compounds with potential applications in indications 
such as obesity, related metabolic conditions and certain neurological conditions.  

Current Programs  

By applying our proprietary MultiStem cell therapy product, we established therapeutic product development programs treating 
inflammatory and immune disorders, neurological conditions, cardiovascular disease, and other conditions. Our programs in the 
clinical development stage include the following:  

• Ischemic Stroke: In our ongoing Phase 2 clinical study, we are evaluating the administration of MultiStem cell 
therapy to patients that have suffered an ischemic stroke. In contrast to treatment with the thrombolytic tPA, which must be 
administered within three to four hours after a stroke, we are treating patients one to two days after the stroke has occurred. 
In preclinical studies, administration of a single dose of MultiStem therapy, even one week after a stroke, resulted in 
significant and durable improvements. This double blind, placebo-controlled trial is being conducted at leading stroke 
centers across the United States and Europe. Enrollment was completed in December 2014. We anticipate announcing the 
interim safety and initial efficacy results in April 2015, following the ninety-day patient evaluation and receipt of the 
unblinded clinical data. Also, in February 2015, we established a collaboration with Chugai to develop and commercialize 
MultiStem for the treatment of ischemic stroke in Japan.  

• Acute Myocardial Infarction: We evaluated the administration of MultiStem to patients that suffered an AMI in a 

Phase 1 clinical study. The results of this study demonstrated a favorable safety profile and encouraging signs of 
improvement in heart function among patients that exhibited severely compromised heart function prior to treatment. This 
data was published in a leading peer reviewed scientific journal, and one-year follow-up data suggested that the benefit 
observed was sustained over time. We were awarded a grant for up to $2.8 million to support the advancement of this 
clinical program, and we are completing preparations for the launch of this Phase 2 clinical study, which we anticipate will 
commence in the second quarter of 2015.  

• Acute Respiratory Distress Syndrome: We were awarded a grant for up to approximately £2.0 million to support an 

initial trial to treat patients suffering from ARDS. ARDS is a serious immunological and inflammatory condition 
characterized by widespread inflammation in the lungs. ARDS can be triggered by pneumonia, sepsis, or other trauma and 
represents a major cause of morbidity and mortality in the critical care setting. The medical need for a safe and effective 
treatment of ARDS is significant due to its high mortality rate, and the number of patients it affects annually. The grant 
supporting this Phase 2a clinical trial was awarded by Innovate UK to our UK subsidiary, Athersys Limited., in 
conjunction with Catapult. We are currently preparing for the trial, which we anticipate will commence in the second half 
of 2015.  

• Hematopoietic Stem Cell Transplant / GvHD: We completed a Phase 1 clinical study of the administration of 
MultiStem cells to patients suffering from leukemia or certain other blood-borne cancers in which patients undergo 
radiation therapy and then receive a hematopoietic stem cell transplant. Such patients are at significant risk for serious 
complications, including graft-versus-host disease, or GvHD, an imbalance of immune system function caused by 
transplanted immune cells that attack various tissues and organs in the patient. Data from the study demonstrated the safety 
of MultiStem cells in this indication and suggested that the therapy may have a beneficial effect in reducing the incidence 
and severity of GvHD, as well as providing other benefits. The MultiStem product has been designated as an orphan drug 
for the GvHD prophylaxis indication by both the FDA and EMA, which may provide market exclusivity and other 
substantial incentives and benefits. We have interacted with both the FDA and EMA to finalize the design of a single 
registration study. In February 2015, the MultiStem product was granted Fast Track designation by the FDA for 
prophylaxis therapy against GvHD following hematopoietic cell transplantation. Currently, we are staging this program for 
future registration-directed development dependent on our other clinical programs and the achievement of certain business 
development and financial objectives.  

34

  
• Inflammatory Bowel Disease: MultiStem therapy is being evaluated in a Phase 2 clinical study involving 

administration of MultiStem to patients suffering from UC, the most common form of IBD. This study is being concluded 
by our collaborative partner, Pfizer, and we released interim results in April 2014. Data collection for the study has run 
through 2014 to complete the secondary evaluations, and subsequent analysis, such as biomarker evaluation and one year 
safety assessment, are being completed by Pfizer in 2015. The interim results obtained from the trial showed that a single 
administration of MultiStem to a patient population with longstanding, chronic advanced disease failed to show a 
meaningful clinical effect at the eight-week evaluation period. Despite not showing a significant improvement compared to 
placebo in the primary efficacy endpoints, the MultiStem therapy demonstrated favorable safety and tolerability in the 
eight weeks following treatment. Furthermore, at four weeks, patients getting MultiStem treatment had a significantly 
higher proportion of rectal bleeding responders than placebo patients, suggesting the possibility of a transient effect from 
the single MultiStem dose. In the event that Pfizer does not move forward with the program, development and 
commercialization rights would revert to us.  

In addition to the programs described above, we are also conducting or supporting clinical activity in other areas, such as solid organ 
transplant, which is an investigator initiated study being conducted at a leading transplant center in Europe. We are also engaged in 
the preparation stages for translational and clinical studies in other targeted areas.  

In addition to our current and anticipated clinical development activities, we are engaged in preclinical development and evaluation of 
MultiStem therapy in other neurological, cardiovascular and inflammatory and immune disease areas, as well as certain other 
indications. We conduct such work both through our own internal research efforts and through a broad global network of 
collaborators.  

We are routinely in discussions with third parties about collaborating in the development of MultiStem therapy for various programs 
and may enter into one or more business partnerships to advance these programs over time.  

We also partnered with RTI on the development of products for certain orthopedic applications using our stem cell technologies in the 
bone graft substitutes market. We began recognizing royalty revenue from product sales in 2014 and may receive other payments 
upon the successful achievement of certain commercial milestones.  

We are also engaged in the development of novel small molecule therapies to treat obesity and other conditions, such as 
schizophrenia. We may elect to enter into a partnership to advance the development of our 5HT2c agonist program, either for the 
treatment of obesity, schizophrenia, or both indications, as well as for certain programs involving MultiStem.  

Financial  

In February 2015, we entered into a collaboration with Chugai to develop and commercialize MultiStem for the treatment of ischemic 
stroke in Japan. Under the terms of the agreement, we received an up-front cash payment of $10 million and are entitled to receive a 
potential near-term payment of $7 million tied to the results of our ongoing Phase 2 clinical trial in ischemic stroke. We may also 
receive additional success-based development and regulatory milestones aggregating up to $38 million, as well as potential sales 
milestones of up to 17.5 billion yen (approximately $150 million based on the current exchange rate). We are also eligible for 
royalties on net sales, starting in the low double digits and increasing incrementally to the high teens depending on net sales levels. 
Additionally, we would receive payments for product supplied to Chugai.  

In January 2014, we completed a registered direct offering generating net proceeds of approximately $18.8 million through the 
issuance of 5,000,000 shares of common stock and warrants to purchase 1,500,000 shares of common stock with an exercise price of 
$4.50 per share that expire on July 15, 2016. The securities were sold in multiples of a fixed combination of one share of common 
stock and a warrant to purchase 0.30 shares of common stock at an offering price of $4.10 per fixed combination.  

We have in place an equity purchase agreement with Aspire Capital, which provides us the ability to sell shares to Aspire Capital 
from time-to-time, as appropriate. As of December 31, 2014, we can elect to sell to Aspire Capital up to an additional $23.5 million of 
shares of common stock under the agreement. During the quarter ended December 31, 2014, no shares were sold under the Aspire 
equity purchase agreement, and during the year ended December 31, 2014, we sold 250,000 shares to Aspire Capital at an average 
price of $3.78. Also, since January 1, 2015 through March 9, 2015, we sold shares for approximately $3.3 million, in aggregate, to 
Aspire Capital.  

35

  
During the year ended December 31, 2014, we received proceeds of approximately $938,000 from the exercise of warrants, resulting 
in the issuance of 928,924 shares of common stock in the aggregate.  

In 2015, we were awarded a grant from Innovate UK, which will support a Phase 2a clinical study evaluating the administration of 
MultiStem cell therapy to ARDS patients. The grant is expected to provide up to approximately £2.0 million in support over the 
course of the study, which will be conducted at leading clinical sites in the UK in conjunction with Catapult, a not-for-profit center 
focused on the development of the UK cell therapy industry. We also received new grant awards in 2014 tied to process development 
and preclinical initiatives.  

Results of Operations  

Since our inception, our revenues have consisted of license fees, contract revenues and milestone payments from our collaborators, 
and grant proceeds primarily from federal, state and foundation grants. We have derived no revenue from the commercial sale of 
therapeutic products to date, but we receive royalties on commercial sales by a licensee of products using our technologies. Research 
and development expenses consist primarily of external clinical and preclinical study fees, manufacturing costs, salaries and related 
personnel costs, legal expenses resulting from intellectual property prosecution processes, facility costs, and laboratory supply and 
reagent costs. We expense research and development costs as they are incurred. We expect to continue to make significant 
investments in research and development to enhance our technologies, advance clinical trials of our product candidates, expand our 
regulatory affairs and product development capabilities, conduct preclinical studies of our product and manufacture our product 
candidates. General and administrative expenses consist primarily of salaries and related personnel costs, professional fees and other 
corporate expenses. We expect to continue to incur substantial losses through at least the next several years.  

Year Ended December 31, 2014 Compared to Year Ended December 31, 2013  

Revenues. Revenues decreased to $1.6 million for the year ended December 31, 2014 from $2.4 million in 2013, reflecting a $0.3 
million decrease in our Pfizer contract revenues and a $0.4 million decrease in milestone payments from Bristol-Myers Squibb, 
partially offset by an increase of $0.2 million in royalty payments from RTI. Absent any new collaborations, we expect our contract 
revenues to be comprised of revenues associated with our recent Chugai collaboration, royalty payments from RTI, potential 
commercial milestone payments from RTI, and potential milestone payments and royalties from Bristol-Myers Squibb. Grant revenue 
decreased $0.3 million for the year ended December 31, 2014 compared to the year ended December 31, 2013, primarily due to 
completed grants and the timing of grant-funded projects. Our grant revenues fluctuate from period-to-period based on new grant 
awards, completed grants and the timing of grant-related activities.  

Research and Development Expenses. Research and development expenses increased to $23.4 million for the year ended 
December 31, 2014 from $20.5 million for the year ended December 31, 2013. The increase of $2.9 million related primarily to an 
increase in personnel costs of $0.9 million, an increase in research supplies of $0.6 million, an increase in clinical and preclinical 
development costs of $0.5 million, an increase in stock-based compensation of $0.5 million, an increase in legal and professional fees 
of $0.1 million, and an increase in other research and development costs of $0.3 million for the year ended December 31, 2014 from 
the comparable period in 2013. Personnel costs rose due to selective personnel additions and annual compensation increases. The 
increase in research supplies was due to an increase in internal process development activities. Our clinical and preclinical 
development costs primarily reflect costs associated with our MultiStem clinical trials and include contract research organization 
costs, clinical manufacturing costs, manufacturing process development costs and clinical consulting costs. The increase in our 
clinical and preclinical costs is primarily due to increased clinical study costs. Stock-based compensation increased primarily due to 
additional months of ratable expense from restricted stock units granted in June 2013, and the implementation of an annual equity 
incentive program in June 2013. The increase in legal fees resulted from increased patent expenses associated with patent prosecution, 
national filings, and interparty proceedings and related filings. Based on our planned clinical development and manufacturing process 
development activities, we expect our 2015 annual research and development expenses to be higher in 2015 as compared to 2014, 
reflecting increased clinical development costs, and such costs will vary over time based on clinical manufacturing campaigns and the 
timing and stage of clinical trials underway. Other than external expenses for our clinical and preclinical programs, we do not track 
our research expenses by project; rather, we track such expenses by the type of cost incurred.  

General and Administrative Expenses. General and administrative expenses increased to $6.9 million in 2014 from $6.1 million in 
2013. The $0.8 million increase in 2014 compared to 2013 was due primarily to an increase of $0.6 million in stock-based 
compensation and an increase in personnel costs of $0.3 million. Stock-based compensation increased in 2014 compared to 2013 
primarily due to additional months of ratable expense from restricted stock units granted in June 2013, and the implementation of an 
annual equity incentive program in June 2013. The increase in personnel costs related to the addition of personnel over the past 
twelve months and annual compensation increases. We expect our general and administrative expenses to continue at similar levels in 
2015.  

36

  
Depreciation. Depreciation expense increased to $0.4 million in 2014 from $0.3 million in 2013 due to depreciation on new capital 
purchases.  

Income (Expense) from Change in Fair Value of Warrants. Income of $6.6 million and expense of $6.3 million was recognized during the 
years ended December 31, 2014 and 2013, respectively, for the market value change in our warrant liabilities. The fluctuation is related to 
the impact of new warrant issuances and changes in warrant value, primarily affected by our stock price and the remaining lives of the 
issued warrants.  

Income Tax Benefit. The income tax benefit in 2014 represents refundable foreign tax credits.  

Other Income (Expense), net. Other income (expense), net, for the years ended December 31, 2014 and 2013 remained relatively 
consistent and was comprised of interest income and expense, and foreign currency gains and losses.  

Year Ended December 31, 2013 Compared to Year Ended December 31, 2012  

Revenues. Revenues decreased to $2.4 million for the year ended December 31, 2013 from $8.7 million for 2012, reflecting a $4.0 million 
decrease in our Pfizer contract revenues and a $2.2 million decrease in our RTI contract revenues. Our 2012 contract revenues included 
the amortization of Pfizer payments, including a $6.0 million up-front license fee, research and development funding, and payments for 
manufacturing services over the estimated performance period that ended in June 2012. Grant revenue increased $0.4 million for the year 
ended December 31, 2013 compared to the year ended December 31, 2012, primarily due to completed grants being replaced with new, 
larger awards, as our grants are focused now on late-stage preclinical and early-stage clinical development programs.  

Research and Development Expenses. Research and development expenses increased to $20.5 million for the year ended December 31, 
2013 from $19.6 million for the year ended December 31, 2012. The increase of $0.9 million is primarily comprised of an increase in 
patent legal fees of $0.6 million, an increase in personnel costs of $0.5 million, an increase in stock-based compensation expense of $0.5 
million, an increase in facility costs of $0.1 million, and an increase in research supplies of $0.1 million for the year ended December 31, 
2013 from the comparable period in 2012. These increases were partially offset by a decrease in clinical and preclinical development 
costs of $0.6 million and a decrease in sponsored research costs of $0.3 million in 2013 compared to 2012. The increase in patent legal 
fees resulted from increased patent expenses associated with patent prosecution, national filings, and interparty proceedings and related 
filings. The increase in personnel costs related to the addition over the past twelve months of personnel supporting our preclinical and 
clinical programs, an annual merit increase in salaries, and increased performance bonus payments. The increase in stock-based 
compensation in 2013 compared to 2012 related primarily to restricted stock units granted to our named executive officers in 2013 in 
exchange for the termination of an old incentive agreement, which vest over a three-year period, and the issuance of stock options to our 
executives as part of the implementation of an annual equity incentive program. Our clinical and preclinical development costs primarily 
reflect costs associated with our MultiStem clinical trials and include contract research organization costs, clinical manufacturing costs, 
manufacturing process development costs and clinical consulting costs. The decrease in our clinical and preclinical costs in 2013 
compared to 2012 relates primarily to fewer manufacturing campaigns and less contract research organization costs for our clinical 
studies, net of increased manufacturing process development costs. Sponsored research costs decreased due to fewer academic research 
institution costs being required under our grant-funded programs. Other than external expenses for our clinical and preclinical programs, 
we do not track our research expenses by project; rather, we track such expenses by the type of cost incurred.  

General and Administrative Expenses. General and administrative expenses increased to $6.1 million in 2013 from $4.8 million in 2012. 
The $1.3 million increase in 2013 compared to 2012 was due primarily to an increase of $0.6 million in stock-based compensation, an 
increase in other general and administrative costs of $0.3 million related to outside services and recruiting costs, an increase in legal and 
professional fees of $0.3 million related primarily to SEC filings, and an increase in personnel costs of $0.2 million. The increase in stock-
based compensation in 2013 compared to 2012 related primarily to restricted stock units granted to our named executive officers in 2013 
in exchange for the termination of an old incentive arrangement, which vest over a three-year period, and the issuance of stock options to 
our executives as part of the implementation of an annual equity incentive program. The increase in outside services related to an increase 
in investor relations costs and advisory fees, as well as our being designated an accelerated filer in 2013, resulting in additional external 
costs associated with the required attestation of internal controls. The increase in legal and professional fees related primarily to required 
additional SEC filings and related activities, and corporate advisory services. The increase in personnel costs related to the addition of 
personnel over the past twelve months, an annual merit increase in salaries, and increased performance bonus payments.  

Depreciation. Depreciation expense was $0.3 million in both 2013 and 2012.  

Income (Expense) from Change in Fair Value of Warrants. Expense of $6.3 million and income of $2.4 million was recognized during the 
years ended 2013 and 2012, respectively, for the change in the valuation of our warrant liabilities.  

37

  
Other Income (Expense), net. In 2013, we had net other income of $38,000 compared to net other expense of $1.1 million in 2012. 
Included in other income (expense), net, are interest income, foreign currency gains and losses, and any realized gains and losses on the 
sale of our assets. Also, included in 2012 were the final cash and stock-based milestone payments to our former lenders in connection 
with our equity offerings amounting to $1.3 million, net of a gain of $183,000 related to an equity-method investment that was 
liquidated in 2012.  

Liquidity and Capital Resources  

Our sources of liquidity include our cash balances and any available-for-sale securities. At December 31, 2014, we had $26.1 million in 
cash and cash equivalents. We have primarily financed our operations through business collaborations, grant funding and equity 
financings. We conduct all of our operations through our subsidiary, ABT Holding Company. Consequently, our ability to fund our 
operations depends on ABT Holding Company’s financial condition and its ability to make dividend payments or other cash 
distributions to us. There are no restrictions such as government regulations or material contractual arrangements that restrict the ability 
of ABT Holding Company to make dividend and other payments to us.  

We incurred losses since inception of operations in 1995 and had an accumulated deficit of $287 million at December 31, 2014. Our 
losses have resulted principally from costs incurred in research and development, clinical and preclinical product development, 
acquisition and licensing costs, and general and administrative costs associated with our operations. We used the financing proceeds 
from equity and debt offerings and other sources of capital to develop our technologies, to discover and develop therapeutic product 
candidates, develop business collaborations and to acquire certain technologies and assets. During the years ended December 2014, 2013 
and 2012, excluding issuances pursuant to our equity purchase arrangement with Aspire Capital described below, we completed 
registered direct, public and private equity offerings generating net proceeds of approximately $18.8 million, $18.4 million and $29.2 
million, respectively.  

In January 2014, we completed a registered direct offering generating net proceeds of approximately $18.8 million through the issuance 
of 5,000,000 shares of common stock and warrants to purchase 1,500,000 shares of common stock with an exercise price of $4.50 per 
share that expire on July 15, 2016. The securities were sold in multiples of a fixed combination of one share of common stock and a 
warrant to purchase 0.30 shares of common stock at an offering price of $4.10 per fixed combination.  

In December 2013, we completed a registered direct offering generating net proceeds of approximately $18.4 million through the 
issuance of 10,000,000 shares of common stock and warrants to purchase 3,500,000 shares of common stock with an exercise price of 
$2.50 per share and an expiration date of March 31, 2015. The securities were sold in multiples of a fixed combination of one share of 
common stock and a warrant to purchase 0.35 shares of common stock at an offering price of $2.00 per fixed combination. In January 
2015, we amended all of the 2013 warrants to purchase 3,500,000 shares of common stock to increase the exercise price to $2.75 per 
share and extend the expiration date to May 31, 2015.  

In November 2011, we entered into an equity purchase agreement with Aspire Capital, which provided that Aspire Capital was 
committed to purchase up to an aggregate of $20.0 million of shares of our common stock over a two-year term, subject to our election 
to sell any such shares. As part of the agreement, Aspire Capital made an initial investment of $1.0 million in us and received 266,667 
additional shares as compensation for its commitment. As of September 2013, we had sold all the remaining shares that were available 
under the 8,000,000 shares of common stock registered for resale under the equity facility, which was due to expire early in 2014. In 
October 2013, we terminated the expiring 2011 equity purchase agreement with Aspire Capital and entered into a new 2013 equity 
purchase agreement with Aspire Capital to purchase up to an aggregate of $25.0 million of shares of our common stock over a new two-
year period. The terms of the 2013 equity facility are similar to the previous arrangement, and we issued 333,333 shares of our common 
stock to Aspire Capital as a commitment fee in October 2013 and filed a registration statement for the resale of 10,000,000 shares of 
common stock in connection with the new equity facility.  

During the years ended December 31, 2014 and 2013, we sold 250,000 and 6,566,666 shares, respectively, to Aspire Capital at average 
prices of $3.78 and $1.70 per share, respectively. As of December 31, 2014, we received proceeds of approximately $14.4 million in 
aggregate under the Aspire equity purchase agreements since its inception in 2011. Also, since January 1, 2015 through March 9, 2015, 
we sold shares for approximately $3.3 million, in aggregate, to Aspire Capital.  

Investors in certain of our equity offerings have received warrants to purchase shares of our common stock, of which warrants to 
purchase an aggregate of 9.3 million shares remain outstanding at December 31, 2014 with a weighted average exercise price of $2.49 
per share. The exercise of warrants could provide us with cash proceeds. During the year ended December 31, 2014, we received 
proceeds of approximately $938,000 from the exercise of warrants, resulting in the issuance of 928,924 shares of common stock in the 
aggregate. During the year ended December 31, 2013, we received proceeds of approximately $402,000 from the exercise of warrants, 
resulting in the issuance of 397,826 shares of common stock in the aggregate. No warrants were exercised in 2012 and 2011. Also, since 
January 1, 2015, we received proceeds of approximately $1.0 million from the exercise of 966,184 warrants.

In connection with our license agreement with Chugai, we received an up-front cash payment of $10 million and are entitled to 
receive a potential near-term payment of $7 million tied to the results of our ongoing Phase 2 clinical trial in ischemic stroke. We may 
also receive additional success-based development and regulatory milestones aggregating up to $38 million, as well as potential sales 
milestones of up to 17.5 billion yen (approximately $150 million based on the current exchange rate). We are also eligible for 
royalties on net sales, starting in the low double digits and increasing incrementally to the high teens depending on net sales levels. 
Additionally, we would receive payments for product supplied to Chugai.  

Under the terms of our agreement with Pfizer, we are eligible to receive milestone payments of up to $105 million upon the 
successful achievement of certain development, regulatory and commercial milestones, though there can be no assurance that we will 
achieve any milestones. No significant milestone payments have been received as of December 31, 2014. Pfizer pays us for 
manufacturing product for clinical development and commercialization purposes. We may elect to co-develop with Pfizer, in which 
case, the parties would share development and commercialization expenses and profits (if any) on an agreed basis beginning at Phase 
3 clinical development. Alternatively, we may elect to not co-develop with Pfizer, in which case Pfizer will pay us tiered single-digit 
royalties on worldwide commercial sales of MultiStem IBD products. Any royalties may be subject to certain reductions related to 
market exclusivity, patent claims and credits from sales milestone payments.  

Under the terms of our RTI agreement, we are eligible to receive cash payments aggregating up to $35.5 million upon the successful 
achievement of certain commercial milestones, though there can be no assurance that such milestones will be achieved, and no 
milestone payments have been received as of December 31, 2014. In addition, we are entitled to receive tiered royalties on worldwide 
commercial sales of implants using our technologies based on a royalty rate starting in the mid-single digits and increasing into the 
mid-teens, and we began receiving royalty payments in 2014.  

We remain entitled to receive license fees for targets that were delivered to Bristol-Myers Squibb under our completed 2001 
collaboration, as well as milestone payments and royalties on compounds developed by Bristol-Myers Squibb using our technology, 
though there can be no assurance that we will achieve any such milestones or royalties.  

We are obligated to pay the University of Minnesota a royalty based on worldwide commercial sales of licensed products if covered 
by a valid licensed patent. The low single-digit royalty rate may be reduced if third-party payments for intellectual property rights are 
necessary or commercially desirable to permit the manufacture or sale of the product.  

In 2012, we entered into an arrangement with the Global Cardiovascular Innovation Center, or GCIC, and the Cleveland Clinic 
Foundation in which we are entitled to proceeds of up to $500,000 in the form of a forgivable loan to fund certain preclinical work. 
Interest on the loan accrues at a fixed rate of 4.25% per annum and is added to the outstanding principal. The loan is forgivable based 
on the achievement of a certain milestone within three to four years. GCIC has agreed to the four-year term, with an expiration date of 
March 31, 2016. As of December 31, 2014, we had drawn $166,000 of this financing ($183,000 including accrued interest).  

In 2015, we were awarded a grant from Innovate UK, which will support a Phase 2a clinical study evaluating the administration of 
MultiStem cell therapy to ARDS patients. The grant is expected to provide up to approximately £2.0 million in support over the 
course of the study, which will be conducted at leading clinical sites in the UK in conjunction with Catapult, a not-for-profit center 
focused on the development of the UK cell therapy industry. We also received new grant awards in 2014 tied to process development 
and preclinical initiatives. In 2013, we were awarded a federal grant that is expected to provide up to $2.8 million in support of a 
Phase 2 clinical study evaluating the administration of MultiStem to patients who have suffered an AMI. In 2012, we were awarded 
grant funding aggregating $3.6 million to further advance our MultiStem programs and cell therapy platform, including further 
development of MultiStem for the treatment of TBI and further development of our cell therapy formulations and manufacturing 
capabilities, from federal, state and European organizations.  

We will require substantial additional funding in order to continue our research and product development programs, including 
preclinical evaluation and clinical trials of our product candidates and manufacturing process development. At December 31, 2014, 
we had available cash and cash equivalents of $26 million, and we intend to meet our short-term liquidity needs with available cash. 
Over the longer term, we will make use of available cash, but will have to continue to generate additional funding to meet our needs, 
through business development opportunities, as well as grant-funding opportunities. Additionally, we are raising capital from time to 
time through the equity purchase agreement with Aspire Capital, subject to its volume and price limitations. We also manage our cash 
by deferring certain discretionary costs and staging certain development costs to extend our operational runway, as needed. Over 
time, we may consider the sale of additional equity securities, or possibly borrowing from financing institutions.  

39

  
Our capital requirements over time depend on a number of factors, including progress in our clinical development programs, our clinical 
and preclinical pipeline of additional opportunities and their stage of development, additional external costs such as payments to contract 
research organizations and contract manufacturing organizations, additional personnel costs, and the costs in filing and prosecuting 
patent applications and enforcing patent claims. The availability of funds impacts our ability to advance multiple clinical programs 
concurrently, and any shortfall in funding could result in our having to delay or curtail research and development efforts. Further, these 
requirements may change at any time due to technological advances, business development activity or competition from other 
companies. We cannot assure you that adequate funding will be available to us or, if available, that it will be available on acceptable 
terms.  

We expect to continue to incur substantial losses through at least the next several years and may incur losses in subsequent periods. The 
amount and timing of our future losses are highly uncertain. Our ability to achieve and thereafter sustain profitability will be dependent 
upon, among other things, successfully developing, commercializing and obtaining regulatory approval or clearances for our 
technologies and products resulting from these technologies.  

Cash Flow Analysis  

Net cash used in operating activities was $25.8 million, $22.8 million and $17.7 million in 2014, 2013 and 2012, respectively, and 
represented the use of cash to fund operations, clinical trials, and preclinical and process development activities. We expect that net cash 
used in operating activities will be higher in total in 2015 compared to 2014 in connection with increased clinical development activities 
for our MultiStem product candidates and platform. Net cash used in operating activities has fluctuated significantly on a quarter-to-
quarter basis over the past few years primarily due to the receipt of collaboration fees and payment of specific clinical trial costs, such as 
clinical manufacturing campaigns, contract research organization costs, and manufacturing process development projects.  

Net cash (used in) provided by investing activities was $(0.3) million, $(0.4) million and $3.9 million in 2014, 2013 and 2012, 
respectively. The fluctuations from period to period were due to the timing of purchases and maturity dates of investments and the 
purchase of equipment. Purchases of equipment were $297,000, $385,000 and $347,000 in 2014, 2013 and 2012, respectively. We 
expect that our capital equipment expenditures will continue at similar levels in 2015 compared to 2014.  

Financing activities provided cash of $20.3 million in 2014 related to the January 2014 registered direct offering, the exercise of 
common stock warrants, and equity sales to Aspire Capital, net of treasury stock purchases. Financing activities provided cash of $29.6 
million in 2013 related to the December 2013 registered direct offering, the exercise of common stock warrants, and equity sales to 
Aspire Capital. Financing activities provided cash of $30.5 million in 2012 related to the March 2012 private placement, the October 
2012 public offering, and equity sales to Aspire Capital.

We lease office and laboratory space under operating leases. Our lease for our corporate offices and laboratories began in 2000 and 
currently expires in March 2016, and we have the option to renew annually through 2019. Our rent is $267,000 per year and our rental 
rate has not changed since the lease inception in 2000. Also, we lease office and laboratory space for our Belgian subsidiary that 
currently expires in July 2015 and includes options to renew annually through July 2022, and the annual rent of approximately $220,000 
is subject to adjustments based on an inflationary index. We also have an option for additional space in Belgium that expires in August 
2015. Our total rent expense for all properties was $517,000 in 2014.

Critical Accounting Policies and Management Estimates  

The SEC defines critical accounting policies as those that are, in management’s view, important to the portrayal of our financial 
condition and results of operation and demanding of management’s judgment. Our discussion and analysis of financial condition and 
results of operations are based on our consolidated financial statements, which have been prepared in accordance with United States 
generally accepted accounting principles. The preparation of these financial statements requires us to make estimates on experience 
and on various assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making 
judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ 
from those estimates.  

A discussion of the material implications of uncertainties associated with the methods, assumptions and estimates underlying our 
critical accounting polices is as follows:  

Revenue Recognition  

Our license and collaboration agreements may contain multiple elements, including license and technology access fees, research and 
development funding, manufacturing revenue, cost-sharing, milestones and royalties. The deliverables under such an arrangement are 
evaluated under Accounting Standards Codification, or ASC, 605-25, Multiple-Element Arrangements. Each required deliverable is 
evaluated to determine whether it qualifies as a separate unit of accounting based on whether the deliverable has “stand–alone value” 
to the customer. The arrangement’s consideration that is fixed or determinable is then allocated to each separate unit of accounting 
based on the relative selling price of each deliverable. In general, the consideration allocated to each unit of accounting is recognized 
as the related goods or services are delivered, limited to the consideration that is not contingent upon future deliverables.  

Revenues that we earned through December 31, 2014 have been recognized under our accounting policy prior to the adoption of ASU 
2009-13, Multiple Deliverable Revenue Arrangement on January 1, 2011. The performance period for our multiple element 
arrangements has concluded.  

For agreements entered into prior to January 1, 2011 and not materially modified thereafter, we continue to apply our prior accounting 
policy with respect to such arrangements. Under this policy, the deliverables under the arrangement are evaluated to assess whether 
they have standalone value and objective and reliable evidence of fair value, and if so, are accounted for as a single unit. We then 
recognize revenue for each unit based on the culmination of the earnings process under ASC 605-S25, issued as Staff Accounting 
Bulletin, or SAB, Topic 13, and our estimated performance period for the single units of accounting based on the specific terms of 
each collaborative agreement. We subsequently adjust the estimated performance periods, if appropriate, on a prospective basis based 
upon available facts and circumstances. Future changes in estimates of the performance period may materially impact the timing of 
future revenue recognized. Amounts received prior to satisfying the revenue recognition criteria for contract revenues are recorded as 
deferred revenue in the accompanying balance sheets. Reimbursement amounts (other than those accounted for using collaboration 
accounting) paid to us are recorded on a gross basis in the statements of operations as contract revenues.  

We recognize revenue from at-risk, performance milestones that are substantive in the period that the milestone is achieved, as 
defined in the respective contracts.  

We entered into collaboration agreements with Pfizer and RTI that contain multiple elements and deliverables. For a description of 
the collaboration agreement and the determination of contract revenues, see Note E to our audited consolidated financial statements. 
In 2015, we will review our license agreement with Chugai for potential multiple elements and deliverables under ASC 605-25.  

Also included in contract revenue are license fees received from Bristol-Myers Squibb, which are specifically set forth in the license 
and collaboration agreement as amounts due to us based on our completion of certain tasks (e.g., delivery and acceptance of a cell 
line) and development milestones (e.g., clinical trial phases), and as such, are not based on estimates that are susceptible to change. 
Such amounts are invoiced and recorded as revenue as tasks are completed and as milestones are achieved.  

Similarly, grant revenue consists of funding under cost reimbursement programs primarily from federal and state sources for qualified 
research and development activities performed by us, and as such, are not based on estimates that are susceptible to change. Such 
amounts are invoiced (unless prepaid) and recorded as revenue as tasks are completed.  

41

  
We recognize revenue from royalties relating to the sale by a licensee of the licensed product. Royalty revenue is recognized on an 
accrual basis in accordance with the substance of the relevant agreement and based on the receipt from the licensee of the relevant 
information to enable calculation of the royalty due.  

Collaborative Arrangements  

Collaborative arrangements that involve cost or future profit sharing are reviewed to determine the nature of the arrangement and the 
nature of the collaborative parties’ businesses. The arrangements are also reviewed to determine if one party has sole or primary 
responsibility for an activity, or whether the parties have shared responsibility for the activity. If responsibility for an activity is 
shared and there is no principal party, then the related costs of that activity are recognized by us on a net basis in the statement of 
operations (e.g., total cost less reimbursement from collaborator). If we are deemed to be the principal party for an activity, then the 
costs and revenues associated with that activity are recognized on a gross basis in the statement of operations. The accounting may be 
susceptible to change if the nature of a collaborator’s business changes. Currently, our only collaboration accounted for on a net basis 
is our cost-sharing collaboration with Angiotech, which was terminated in 2011. In 2015, we will review our license agreement and 
collaboration with Chugai for potential accounting as a collaborative arrangement.  

Clinical Trial Costs  

Clinical trial costs are accrued based on work performed by outside contractors that manage and perform the trials. We obtain initial 
estimates of total costs based on enrollment of subjects, project management estimates and other activities. Actual costs are typically 
charged to us and recognized as the tasks are completed by the contractor, and if we are invoiced based on progress payments as 
opposed to actual costs, we develop estimates of work completed to date. Accrued clinical trial costs may be subject to revisions as 
clinical trials progress, and any revisions are recorded in the period in which the facts that give rise to the revisions become known.  

Stock-Based Compensation  

We recognize stock-based compensation expense on the straight-line method and use a Black-Scholes option-pricing model to 
estimate the grant-date fair value of share-based awards. The expected term of options granted represent the period of time that option 
grants are expected to be outstanding. We use the “simplified” method to calculate the expected life of option grants given our limited 
history and determine volatility by using our historical stock volatility. Estimates of fair value are not intended to predict actual future 
events or the value ultimately realized by persons who receive equity awards.  

Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those 
estimates and if our expectations on forfeitures changes. If actual forfeitures vary from the estimate, we will recognize the difference 
in compensation expense in the period the actual forfeitures occur or when options vest.  

All of the aforementioned estimates and assumptions are evaluated on a quarterly basis and may change as facts and circumstances 
warrant. Changes in these assumptions can materially affect the estimate of the fair value of our share-based payments and the related 
amount recognized in our financial statements.  

Fair Value of Warrant Liabilities  

The estimated fair value of warrants accounted for as liabilities, representing a level 3 fair value measure, is determined on the 
issuance date and subsequently marked to market at each financial reporting date. The fair value of the warrants is estimated using the 
expected volatility based on our historical volatility for warrants issued after January 1, 2013, or for warrants issued prior to 2013, 
using the historical volatilities of comparable companies from a representative peer group selected based on industry and market 
capitalization, each of which using a Black-Scholes pricing model. The fair value of certain warrants is determined using probability 
weighted-average assumptions that give consideration to contractual terms in the warrants, such as an exercise price repricing feature, 
as defined.

CAUTIONARY NOTE ON FORWARD-LOOKING STATEMENTS 

This annual report on Form 10-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform 
Act of 1995 that involve risks and uncertainties. These forward-looking statements relate to, among other things, the expected 
timetable for development of our product candidates, our growth strategy, and our future financial performance, including our 
operations, economic performance, financial condition, prospects, and other future events. We have attempted to identify forward-
looking statements by using such words as “anticipates,” “believes,” “can,” “continue,” “could,” “estimates,” “expects,” “intends,” 
“may,” “plans,” “potential,” “should,” “suggest,” “will,” or other similar expressions. These forward-looking statements are only 
predictions and are largely based on our current expectations. These forward-looking statements appear in a number of places in this 
annual report.  

In addition, a number of known and unknown risks, uncertainties, and other factors could affect the accuracy of these statements. 
Some of the more significant known risks that we face are the risks and uncertainties inherent in the process of discovering, 
developing, and commercializing products that are safe and effective for use as human therapeutics, including the uncertainty 
regarding market acceptance of our product candidates and our ability to generate revenues. The following risks and uncertainties 
may cause our actual results, levels of activity, performance, or achievements to differ materially from any future results, levels of 
activity, performance, or achievements expressed or implied by these forward-looking statements:

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

Interest Rate Risk  

Our exposure to interest rate risk is related to our investment portfolio and our borrowings. Fixed rate investments and borrowings 
may have their fair market value adversely impacted from changes in interest rates. Due in part to these factors, our future investment 
income may fall short of expectations. Further, we may suffer losses in investment principal if we are forced to sell securities that 
have declined in market value due to changes in interest rates. When appropriate based on interest rates, we invest our excess cash 
primarily in debt instruments of the United States government and its agencies and corporate debt securities, and as of December 31, 
2014, we had no investments. We have been investing conservatively due to the current economic conditions and have prioritized 
liquidity and the preservation of principal in lieu of potentially higher returns. As a result, we experienced no losses on the principal 
of our investments.  

We enter into loan arrangements with financial institutions when needed and when available to us. At December 31, 2014, we had no 
borrowings outstanding other than a forgivable note payable associated with local grant funding bearing fixed, forgivable interest of 
4.25% per annum.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Stockholders  
Athersys, Inc.  

We have audited the accompanying consolidated balance sheets of Athersys, Inc. as of December 31, 2014 and 2013, and the related 
consolidated statements of operations and comprehensive loss, stockholders’ equity and cash flows for each of the three years in the 
period ended December 31, 2014. Our audits also included the financial statement schedule listed in the Index at Item 15(a) (2). These 
financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
these financial statements and schedule based on our audits.  

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are 
free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the 
financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, 
as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our 
opinion.  

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of 
Athersys, Inc. at December 31, 2014 and 2013, and the consolidated results of its operations and its cash flows for each of the three 
years in the period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, 
the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly 
in all material respects the information set forth therein.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
Athersys, Inc.‘s internal control over financial reporting as of December 31, 2014, 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 12, 2015 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm 

The Board of Directors and Stockholders  
Athersys, Inc.  

We have audited Athersys, Inc.’s internal control over financial reporting as of December 31, 2014, 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). Athersys Inc.’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 in Item 9A. Our responsibility is to express an opinion on the 
company’s internal control over financial reporting based on our audit.  

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 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.  

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.  

In our opinion, Athersys, Inc. maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2014, based on the COSO criteria.  

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
consolidated balance sheets as of December 31, 2014 and 2013, and the related consolidated statements of operations and 
comprehensive loss, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2014 of 
Athersys, Inc. and our report dated March 12, 2015 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements  

A. Background  

We are an international biotechnology company that is focused primarily in the field of regenerative medicine and operate in one 
business segment. Our operations consist primarily of research and product development activities.  

B. Accounting Policies  

Principles of Consolidation  

The consolidated financial statements include our accounts and results of operations and those of our wholly-owned subsidiaries. All 
intercompany accounts and transactions have been eliminated in consolidation. Investments in joint ventures are accounted for using 
the equity method when we do not control the investee, but have the ability to exercise significant influence over the investee’s 
operations and financial policies. We liquidated an investment in an inactive joint venture in 2012 and recognized a gain of $183,000. 

Revenue Recognition  

Our license and collaboration agreements may contain multiple elements, including license and technology access fees, research and 
development funding, manufacturing revenue, cost-sharing, milestones and royalties. The deliverables under such an arrangement are 
evaluated under Accounting Standards Codification (“ASC”) 605-25, Multiple-Element Arrangements. Each required deliverable is 
evaluated to determine whether it qualifies as a separate unit of accounting based on whether the deliverable has “stand-alone value” 
to the customer. The arrangement’s consideration that is fixed or determinable is then allocated to each separate unit of accounting 
based on the relative selling price of each deliverable. In general, the consideration allocated to each unit of accounting is recognized 
as the related goods or services are delivered, limited to the consideration that is not contingent upon future deliverables.  

Revenues that we have earned through December 31, 2014 have been recognized under our accounting policy prior to the adoption of 
ASU 2009-13, Multiple-Deliverable Revenue Arrangements on January 1, 2011. The performance period for our multiple element 
arrangements have concluded..  

For agreements entered into prior to January 1, 2011 and not materially modified thereafter, we continue to apply our prior accounting 
policy with respect to such arrangements. Under this policy, the deliverables under the arrangement are evaluated to assess whether 
they have standalone value and objective and reliable evidence of fair value, and if so, are accounted for as a single unit. We then 
recognize revenue for each unit based on the culmination of the earnings process under ASC 605-S25, issued as Staff Accounting 
Bulletin (“SAB”) Topic 13, and our estimated performance period for the single units of accounting based on the specific terms of 
each collaborative agreement. We subsequently adjust the estimated performance periods, if appropriate, on a prospective basis based 
upon available facts and circumstances. Future changes in estimates of the performance period may materially impact the timing of 
future revenue recognized. Amounts received prior to satisfying the revenue recognition criteria for contract revenues are recorded as 
deferred revenue in the accompanying balance sheets. Reimbursement amounts (other than those accounted for using collaboration 
accounting) paid to us are recorded on a gross basis in the statements of operations as contract revenues.  

We recognize revenue from at-risk, performance milestones that are substantive in the period that the milestone is achieved, as 
defined in the respective contracts.  

Also included in contract revenue are license fees received from Bristol-Myers Squibb, which are specifically set forth in the license 
and collaboration agreement as amounts due to us based on our completion of certain tasks (e.g., delivery and acceptance of a cell 
line) and development milestones (e.g., clinical trial phases), and as such, are not based on estimates that are susceptible to change. 
Such amounts are invoiced and recorded as revenue as tasks are completed and as milestones are achieved.  

Similarly, grant revenue consists of funding under cost reimbursement programs primarily from federal and state sources for qualified 
research and development activities performed by us, and as such, are not based on estimates that are susceptible to change. Such 
amounts are invoiced (unless prepaid) and recorded as revenue as tasks are completed.  

52

  
We recognize revenue from royalties relating to the sale by a licensee of the licensed product. Royalty revenue is recognized on an accrual 
basis in accordance with the substance of the relevant agreement and based on the receipt from the licensee of the relevant information to 
enable calculation of the royalty due.  

Cash and Cash Equivalents  

We consider all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents 
are primarily invested in money market funds and commercial paper. The carrying amount of our cash equivalents approximates fair value 
due to the short maturity of the investments.  

Research and Development  

Research and development expenditures, which consist primarily of costs associated with external clinical and preclinical study fees, 
manufacturing costs, salaries and related personnel costs, legal expenses resulting from intellectual property application processes, and 
laboratory supply and reagent costs, including direct and allocated overhead expenses, are charged to expense as incurred.  

Collaborative Arrangements  

Collaborative arrangements that involve cost or future profit sharing are reviewed to determine the nature of the arrangement and the nature 
of the collaborative parties’ businesses. The arrangements are also reviewed to determine if one party has sole or primary responsibility for 
an activity, or whether the parties have shared responsibility for the activity. If responsibility for an activity is shared and there is no 
principal party, then the related costs of that activity are recognized by us on a net basis in the statement of operations (e.g., total cost less 
reimbursement from collaborator). If we are deemed to be the principal party for an activity, then the costs and revenues associated with that 
activity are recognized on a gross basis in the statement of operations. The accounting may be susceptible to change if the nature of a 
collaborator’s business changes. Currently, we have no collaborations accounted for on a net basis.  

Clinical Trial Costs  

Clinical trial costs are accrued based on work performed by outside contractors that manage and perform the trials. We obtain initial 
estimates of total costs based on enrollment of subjects, project management estimates and other activities. Actual costs are typically charged 
to us and recognized as the tasks are completed by the contractor, and if we are invoiced based on progress payments as opposed to actual 
costs, we develop estimates of work completed to date. Accrued clinical trial costs may be subject to revisions as clinical trials progress, and 
any revisions are recorded in the period in which the facts that give rise to the revisions become known.  

Royalties  

We may be required to make future royalty payments to certain parties based on product sales under license agreements. We did not pay any 
royalties during the three-year period ended December 31, 2014.  

Investments in Available-for-Sale Securities  

We determine the appropriate classification of investment securities at the time of purchase and re-evaluate such designation as of each 
balance sheet date. Our investments typically consist of United States government obligations and corporate debt securities, which are 
classified as available-for-sale and are valued based on quoted prices in active markets for identical assets. Available-for-sale securities are 
carried at fair value, with the unrealized gains and losses, net of applicable tax, reported as a component of accumulated other comprehensive 
income. The amortized cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such 
amortization or accretion is included in interest income. Realized gains and losses on available-for-sale securities are included in interest 
income. The cost of securities sold is based on the specific identification method. Interest earned on securities classified as available-for-sale 
is included in interest income.  

Long-Lived Assets  

Equipment is stated at acquired cost less accumulated depreciation. Laboratory and office equipment are depreciated on the straight-line 
basis over the estimated useful lives (three to ten years). Leasehold improvements are amortized over the shorter of the lease term or 
estimated useful life.  

Long-lived assets are evaluated for impairment when events or changes in circumstances indicate that the carrying amount of the asset or 
related group of assets may not be recoverable. If the expected future undiscounted cash flows are less than the carrying amount of the asset, 
an impairment loss is recognized at that time. Measurement of impairment may be based upon appraisal, market value of similar assets or 
discounted cash flows.  

53

  
Patent Costs and Rights  

Costs of prosecuting and maintaining patents and patent rights are expensed as incurred. We have filed for broad intellectual property 
protection on our proprietary technologies. We currently have numerous United States patent applications and corresponding 
international patent applications related to our technologies, as well as many issued United States and international patents.  

Warrant Liabilities  

We account for common stock warrants as either liabilities or as equity instruments depending on the specific terms of the warrant 
agreements. Registered common stock warrants that could require cash settlement are accounted for as liabilities. We classify these 
warrant liabilities on the consolidated balance sheet as non-current liabilities. The warrant liabilities are revalued at fair value at each 
balance sheet date subsequent to the initial issuance. Changes in the fair market value of the warrants are reflected in the consolidated 
statement of operations as income (expense) from change in fair value of warrants.  

Treasury Stock  

Treasury stock is recorded at cost and any difference between the cost basis and the selling price of treasury stock is recognized as 
additional paid-in capital. Treasury stock is relieved on a first-in-first-out basis at actual cost. At December 31, 2014, we had no 
shares of common stock held in treasury, and at December 31, 2013, we had 65,732 shares of common stock held in treasury and 
available for reissuance.  

Comprehensive Loss  

The proportional share of comprehensive income and loss of our equity method investment, which was liquidated in 2012, is the only 
component of accumulated other comprehensive loss.  

Concentration of Credit Risk  

Our accounts receivable are generally comprised of amounts due from collaborators and granting authorities and are subject to 
concentration of credit risk due to the absence of a large number of customers. At December 31, 2014, the majority of our accounts 
receivable are due from collaborators. We do not require collateral from these customers.  

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 amounts reported in the financial statements and accompanying notes. 
Actual results could differ from those estimates.  

Stock-Based Compensation  

We recognize stock-based compensation expense on the straight-line method and use a Black-Scholes option-pricing model to 
estimate the fair value of option awards. The expected term of options granted represent the period of time that option grants are 
expected to be outstanding. We use the “simplified” method to calculate the expected life of option grants given our limited history of 
exercise activity and determine volatility by using our historical stock volatility. The fair value of our restricted stock units are equal 
to the closing price of our common stock on the date of grant and is expensed over the vesting period on a straight-line basis. 
Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons that receive equity 
awards.  

Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those 
estimates. If actual forfeitures vary from the estimate, we recognize the difference in compensation expense in the period the actual 
forfeitures occur or when options vest.  

All of the aforementioned estimates and assumptions are evaluated on a quarterly basis and may change as facts and circumstances 
warrant. Changes in these assumptions can materially affect the estimate of the fair value of our share-based payments and the related 
amount recognized in our financial statements.

Deferred tax liabilities and assets are determined based on the differences between the financial reporting and tax basis of assets and 
liabilities and are measured using the tax rate and laws currently in effect. We evaluate our deferred income taxes to determine if a 
valuation allowance should be established against the deferred tax assets or if the valuation allowance should be reduced based on 
consideration of all available evidence, both positive and negative, using a “more likely than not” standard.  

We had no liability for uncertain income tax positions as of December 31, 2014 and 2013. Our policy is to recognize potential 
accrued interest and penalties related to the liability for uncertain tax benefits, if applicable, in income tax expense. Net operating loss 
and credit carryforwards since inception remain open to examination by taxing authorities, and will for a period post utilization.  

Net Loss per Share  

Basic and diluted net loss per share have been computed using the weighted-average number of shares of common stock outstanding 
during the period. For each reporting period, we evaluate the income from our warrant liabilities and consider whether it results in a 
potentially dilutive effect to net loss per share. For the year ended December 31, 2014, we had such a dilutive reconciliation related to 
our warrants with an exercise price of $1.01, which are included in the table below. Any such warrants are then omitted from the 
subsequent following table of instruments that were excluded from the calculation of diluted net loss per share. The table below 
reconciles the net loss and the number of shares used to calculate basic and diluted net loss per share for the years ended 
December 31, 2014, 2013 and 2012, in thousands.

Recently Issued Accounting Standards  

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with 
Customers. ASU 2014-09 requires an entity to recognize revenue in a manner that depicts the transfer of promised goods or services 
to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or 
services. To achieve that core principle, the amendment provides five steps that an entity should apply when recognizing revenue. The 
amendment also specifies the accounting of some costs to obtain or fulfill a contract with a customer and expands the disclosure 
requirements around contracts with customers. An entity can either adopt this amendment retrospectively to each prior reporting 
period presented or retrospectively with the cumulative effect of initially applying the update recognized at the date of initial 
application. The amendment is effective for annual reporting periods beginning after December 15, 2016. Early adoption is not 
permitted. We are in the process of evaluating, but have not determined, the impact that the adoption of ASU 2014-09 will have on 
our consolidated financial statements.  

In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern, Disclosure of Uncertainties 
about an Entity’s Ability to Continue as a Going Concern, which establishes management’s responsibility to evaluate whether there is 
substantial doubt about an entity’s ability to continue as a going concern and, if so, to provide related footnote disclosures. ASU 
2014-15 provides a definition of the term ‘substantial doubt’ and requires an assessment for a period of one year after the date that the 
financial statements are issued or available to be issued. Management will also be required to evaluate and disclose whether its plans 
alleviate that doubt. The guidance is effective for the annual periods ending after December 15, 2016 and interim periods thereafter 
with early adoption permitted. We are in the process of evaluating the impact the new guidance will have on our disclosures.

Fair Value Measurements  

We classify the inputs used to measure fair value into the following hierarchy:  

Level 1

Level 2

Unadjusted quoted prices in active markets for identical assets or liabilities.

Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or 
similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the 
asset or liability.

We review and reassess the fair value hierarchy classifications on a quarterly basis. Changes from one quarter to the next related to 
the observability of inputs in a fair value measurement may result in a reclassification between fair value hierarchy levels. There were 
no reclassifications for all periods presented.  

The estimated fair value of warrants accounted for as liabilities, representing a level 3 fair value measure, was determined on the 
issuance date and subsequently marked to market at each financial reporting date. We use the Black-Scholes valuation model to value 
the warrant liabilities at fair value. The fair value is estimated using the expected volatility based on our historical volatility for 
warrants issued after January 1, 2013, or for warrants issued prior to 2013, using the historical volatilities of comparable companies 
from a representative peer group selected based on industry and market capitalization. The fair value of the warrants is determined 
using probability weighted-average assumptions, when appropriate. The following inputs were used at December 31, 2014:

Financing Arrangements  

We lease office and laboratory space under operating leases. The lease for our corporate offices and laboratories began in 2000 and 
currently expires in March 2016, and we have the option to renew annually through 2019. Our rent is $267,000 per year and our rental 
rate has not changed since the lease inception in 2000. Also, we lease office and laboratory space for our Belgian subsidiary, which 
currently expires in July 2015 and includes options to renew annually through July 2022, with annual rent of approximately $220,000, 
subject to adjustments based on an inflationary index. We also have an option for additional space in Belgium that expires in August 
2015.  

Aggregate rent expense was approximately $517,000, $491,000 and $415,000 in 2014, 2013 and 2012, respectively. The future 
annual minimum lease commitments at December 31, 2014 are approximately $370,000 for 2015 and $67,000 for 2016.

In 2012, we entered into an arrangement with the Global Cardiovascular Innovation Center (“GCIC”) and the Cleveland Clinic 
Foundation pursuant to which we are entitled to proceeds of up to $500,000 in the form of a forgivable loan to fund certain remaining 
preclinical work using MultiStem to treat congestive heart failure and for preparing the program for an investigational new drug 
application with the United States Food and Drug Administration. Interest on the loan accrues at a fixed rate of 4.25% per annum, and 
is added to the outstanding principal. The principal and interest on the loan will be forgiven based on the achievement of a certain 
milestone, unrelated to the preclinical work, within three to four years. GCIC has agreed to the four-year term, with an expiration date 
of March 31, 2016. As of December 31, 2014 and 2013, we have drawn $166,000 of this financing ($183,000 including interest), 
which is reflected on the balance sheet as a non-current note. The fair value of our note payable at December 31, 2014 is not 
determinable due to lack of marketability of the note payable.  

Our former lenders retained a right to receive remaining milestone payments up to $1.3 million as of December 31, 2011 (from an 
original amount of $2.25 million) upon the occurrence of certain events, and the final balance was settled in full in 2012 in connection 
with equity offerings during the year. We elected to pay 75% of the milestone payments in shares of common stock at the per-share 
offering prices in 2012 and $1.3 million in cash and stock-based milestone payments were recognized as other expense in 2012.  

We paid no interest during the three years ended December 31, 2014.  

E. Collaborations and Revenue Recognition  

Pfizer  

In 2009, we entered into a collaboration with Pfizer Inc. (“Pfizer”) to develop and commercialize our MultiStem® product candidate 
to treat inflammatory bowel disease (“IBD”) for the worldwide market on an exclusive basis. Under the terms of the agreement, we 
received a non-refundable up-front payment from Pfizer and research funding and support through June 2012. We are eligible to 
receive milestone payments upon the successful achievement of certain development, regulatory and commercial milestones, for 
which we evaluated the nature of the events triggering these contingent payments and concluded that these events constituted 
substantive milestones that will be recognized as revenue in the period in which the underlying triggering event occurs. In concluding 
that each milestone is substantive, we considered factors such as whether the associated consideration fairly represents either the level 
of effort required to reach the milestone or the value added to the product based on the achievement of such milestone. No significant 
milestone revenue has been recognized to date.  

Pfizer pays us for manufacturing product for clinical development and commercialization purposes, which is recognized in the period 
that the manufacturing services are performed. Pfizer has responsibility for development and regulatory activities, including decision-
making regarding the advancement or cessation of further development under the collaboration. If the product is successfully 
developed, Pfizer would also have sole responsibility for commercialization. We may elect to co-develop with Pfizer, in which case, 
the parties would share development and commercialization expenses and profits, if any, on an agreed-upon basis beginning at Phase 
3 clinical development. Alternatively, we may elect to not co-develop with Pfizer, in which case Pfizer will pay us tiered single-digit 
royalties on worldwide commercial sales of MultiStem IBD products. Any royalties may be subject to certain reductions related to 
market exclusivity, patent claims and credits from sales milestone payments. In the event that Pfizer does not move the program 
forward, the development and commercialization rights would revert to us.  

RTI Surgical, Inc.  

In 2010, we entered into an agreement with RTI Surgical, Inc. (“RTI”) to develop and commercialize biologic implants using our 
technology for certain orthopedic applications in the bone graft substitutes market on an exclusive basis. Under the terms of the 
agreement, we received a non-refundable license fee in installments and performed certain services that were concluded in 2012. We 
are eligible to receive cash payments upon the successful achievement of certain commercial milestones. We evaluated the nature of 
the events triggering these contingent payments and concluded that these events are substantive and that revenue will be recognized in 
the period in which each underlying triggering event occurs. No milestone revenue has been recognized to date. In addition, we are 
entitled to receive tiered royalties on worldwide commercial sales of implants using our technologies based on a royalty rate starting 
in the mid-single digits and increasing into the mid-teens. Any royalties may be subject to a reduction if third-party payments for 
intellectual property rights are necessary or commercially desirable to permit the manufacture or sale of the product.  

F. Capitalization and Warrant Liability  

Capitalization  

At both December 31, 2014 and 2013, we had 150.0 million shares of common stock and 10.0 million shares of undesignated 
preferred stock authorized. No shares of preferred stock have been issued as of December 31, 2014.

In January 2014, we completed a registered direct offering generating net proceeds of approximately $18.8 million through the 
issuance of 5,000,000 shares of common stock and immediately exercisable warrants to purchase 1,500,000 shares of common stock 
with an exercise price of $4.50 per share that expire on July 15, 2016. The securities were sold in multiples of a fixed combination of 
one share of common stock and a warrant to purchase 0.30 shares of common stock at an offering price of $4.10 per fixed 
combination.  

In December 2013, we completed a registered direct offering generating net proceeds of approximately $18.4 million through the 
issuance of 10,000,000 shares of common stock and warrants to purchase 3,500,000 shares of common stock with an exercise price of 
$2.50 per share and an expiration date of March 31, 2015. When the 3,500,000 warrants were issued, 1,401,218 were not exercisable 
until June 3, 2014. The securities were sold in multiples of a fixed combination of one share of common stock and a warrant to 
purchase 0.35 shares of common stock at an offering price of $2.00 per fixed combination. In January 2015, we amended all of the 
December 2013 warrants to purchase 3,500,000 shares of common stock to increase the exercise price from $2.50 to $2.75 per share, 
and to extend the expiration date from March 31, 2015 to May 31, 2015.  

In October 2012, we completed a public offering generating net proceeds of approximately $18.3 million through the issuance of 
19,802,000 shares of common stock at a price of $1.01 per share. In November 2012, the underwriters exercised in full their right to 
purchase an additional 2,970,300 shares of common stock, solely to cover over-allotments. The exercise of the full over-allotment 
option generated an additional $2.8 million of net proceeds.  

In March 2012, we completed a private placement financing generating net proceeds of approximately $8.1 million through the 
issuance of 4,347,827 shares of common stock and five-year warrants to purchase 4,347,827 shares of common stock with an exercise 
price of $2.07 per share. The securities were sold in multiples of a fixed combination of one share of common stock and a warrant to 
purchase one share of common stock at an offering price of $2.07 per fixed combination, and the warrants include price protection in 
the event we sell stock below the exercise price, as defined. As a result of the October 2012 public offering and in accordance with 
the terms of the warrants, we sought and obtained stockholder approval in February 2013 to reduce the exercise price of these 
warrants to $1.01 per share. Warrants to purchase 2,292,934 shares of common stock have been exercised to date, resulting in 
aggregate proceeds of $2.3 million.  

In February 2011, we completed a registered direct offering with net proceeds of $11.8 million through the issuance of 4,366,667 
shares of common stock and five-year warrants to purchase 1,310,000 shares of common stock with an exercise price of $3.55 per 
share. The securities were sold in multiples of a fixed combination of one share of common stock and a warrant to purchase 0.3 of a 
share of common stock at an offering price of $3.00 per fixed combination.

Aspire Capital  

In November 2011, we entered into an equity purchase agreement with Aspire Capital Fund, LLC (“Aspire Capital”), which provided 
that Aspire Capital was committed to purchase up to an aggregate of $20.0 million of shares of our common stock over a two-year 
term, subject to our election to sell any such shares. Under the agreement, we have the right to sell shares, subject to certain volume 
limitations and a minimum floor price, at a modest discount to the prevailing market price. As part of the agreement, Aspire Capital 
made an initial investment of $1.0 million in us and received 266,667 additional shares as compensation for its commitment. As of 
September 2013, we had sold all the remaining shares that were available under the 8,000,000 shares of common stock registered for 
resale under the equity facility, which was due to expire early in 2014. In October 2013, we terminated the expiring 2011 equity 
purchase agreement with Aspire Capital and entered into a new 2013 equity purchase agreement with Aspire Capital to purchase up to 
an aggregate of $25.0 million of shares of our common stock over a new two-year period. The terms of the 2013 equity facility are 
similar to the previous arrangement, and we issued 333,333 shares of our common stock Aspire Capital as a commitment fee in 
October 2013 and filed a registration statement for the resale of 10,000,000 shares of common stock in connection with the new 
equity facility.  

During the years ended December 31, 2014 and 2013, we sold 250,000 and 6,566,666 shares, respectively, to Aspire Capital at 
average prices of $3.78 and $1.70 per share, respectively. As of December 31, 2014, we received proceeds of approximately $14.4 
million in aggregate under the Aspire equity purchase agreements since their inception in 2011, and we can elect to sell to Aspire 
Capital up to an additional $23.5 million of shares of common stock under the current agreement. Since January 1, 2015 through 
March 9, 2015, we sold shares for approximately $3.3 million, in aggregate, to Aspire Capital.  

Warrant Liabilities  

The warrants we issued in the January 2014 and December 2013 registered direct offerings contain a provision for a cash payment in 
the event that the shares are not delivered to the holder within two trading days. The cash payment equals $10 per day per $2,000 of 
warrant shares for each day late. The warrants we issued in both the March 2012 private placement and the February 2011 registered 
direct offering each contain a provision for net cash settlement in the event that there is a fundamental transaction (e.g., merger, sale 
of substantially all assets, tender offer, or share exchange). If a fundamental transaction occurs in which the consideration issued 
consists of all cash or stock in a non-public company, then the warrant holder has the option to receive cash equal to a Black Scholes 
value of the remaining unexercised portion of the warrant. Further, the March 2012 warrants include price protection in the event we 
sell stock below the exercise price, as defined, and the exercise price was reduced in February 2013 to $1.01 per share as a result of 
the October 2012 public offering.  

The warrants have been classified as liabilities, as opposed to equity, due to the potential adjustment to the exercise price that could 
result upon late delivery of the shares or potential cash settlement upon the occurrence of certain events as described above, and are 
recorded at their fair values at each balance sheet date.  

G. Stock-Based Compensation  

We have two incentive plans that authorized an aggregate of 11,500,000 shares of common stock for awards to employees, directors 
and consultants, which reflects an increase in shares authorized of 6,000,000 that was approved in 2013. These equity incentive plans 
authorize the issuance of equity-based compensation in the form of stock options, stock appreciation rights, restricted stock, restricted 
stock units, performance shares and units, and other stock-based awards to qualified employees, directors and consultants. As of 
December 31, 2014, a total of 1,596,417 shares of common stock have been issued under our equity incentive plans.  

As of December 31, 2014, a total of 1,630,859 shares were available for issuance under our equity compensation plans and stock-
based awards to purchase 8,272,724 shares of common stock were outstanding. We recognized $2,605,000, $1,523,000 and $481,000 
of stock-based compensation expense in 2014, 2013 and 2012, respectively.  

Stock Options  

The weighted average fair value of options granted in 2014, 2013 and 2012 was $1.29, $1.42 and $1.21 per share, respectively. The 
total fair value of options vested during 2014, 2013 and 2012 was $940,000, $585,000 and $420,000, respectively. At December 31, 
2014, total unrecognized estimated compensation cost related to unvested stock options was approximately $2,559,000, which is 
expected to be recognized by mid-2018 using the straight-line method. The weighted average contractual life of unvested options at 
December 31, 2014 was 9.07 years. The aggregate intrinsic value of fully vested option shares and option shares expected to vest as 
of December 31, 2014 was $30,000.

The total fair value of restricted stock units vested during 2014, 2013 and 2012 was $1,734,000, $805,000 and $26,000, respectively. 
At December 31, 2014, total unrecognized estimated compensation cost related to unvested restricted stock units was approximately 
$2,991,000, which is expected to be recognized by mid-2018 using the straight-line method.  

H. Income Taxes  

At December 31, 2014, we had U.S. federal net operating loss and research and development tax credit carryforwards of 
approximately $88,283,000 and $2,934,000, respectively. Such operating losses and tax credits may be used to reduce future taxable 
income and tax liabilities and will expire at various dates between 2019 and 2035. We also had foreign net operating loss and foreign 
tax credit carryforwards of approximately $12,170,000 and $200,000, respectively. Such foreign operating losses do not expire and 
tax credits will expire between 2015 and 2019. We also had state and city net operating loss carryforwards aggregating approximately 
$35,994,000. Such operating losses may be used to reduce future taxable income and tax liabilities and will expire at various dates 
between 2015 and 2035.  

The utilization of net operating loss and tax credit carryforwards generated prior to October 2012 (“Section 382 Limited Attributes”) 
is substantially limited under Section 382 of the Internal Revenue Code as a result of our equity offering in October 2012. U.S. 
federal net operating loss carryforwards of $48,213,000, research and development tax credits of $2,723,000, and state and local net 
operating loss carryforwards of $29,218,000 generated in 2014 and 2013, as well as foreign net operating loss carryforwards of 
$12,170,000 and foreign tax credits of $200,000, are not subject to annual limitations. The Section 382 Limited Attributes may be 
used to reduce future taxable income and tax liabilities and will expire at various dates between 2015 and 2031.

Because of our cumulative losses, substantially all of the deferred tax assets have been offset by a valuation allowance. We have not 
paid income taxes for the three-year period ended December 31, 2014. In 2014, we recognized a refundable tax benefit related to 
research and development credits associated with our foreign subsidiary.  

I. Profit Sharing Plan and 401(k) Plan  

We have a profit sharing and 401(k) plan that covers substantially all employees and allows for discretionary contributions by us. We 
make employer contributions to this plan, and the expense was approximately $284,000 in 2014, $97,000 in 2013, and $98,000 in 
2012.  

J. Subsequent Events  

Chugai Collaboration  

In February 2015, we entered into a collaboration with Chugai Pharmaceutical Co., Ltd (“Chugai”) to develop and commercialize 
MultiStem cell therapy for ischemic stroke in Japan on an exclusive basis. Under the agreement, Chugai will be responsible for the 
development and commercialization of MultiStem for ischemic stroke in Japan, and we will have the primary responsibility for the 
manufacture of product for both clinical and commercial purposes. The parties will coordinate Japanese and global regulatory 
activities and clinical development plans for MultiStem treatment of ischemic stroke.

In accordance with the agreement, we received an up-front cash payment of $10 million and are entitled to receive a potential near-
term payment of $7 million tied to the results of our ongoing Phase 2 clinical trial in ischemic stroke. We may also receive additional 
success-based development and regulatory milestones aggregating up to $38 million, as well as potential sales milestones of up to 
17.5 billion yen (approximately $150 million based on the current exchange rate). We are also eligible for royalties on net sales, 
starting in the low double digits and increasing incrementally to the high teens depending on net sales levels. Additionally, we would 
receive payments for product supplied to Chugai.  

Grant Award  

In 2015, we were awarded a grant from Innovate UK in support of a Phase 2a clinical study evaluating the administration of 
MultiStem cell therapy to acute respiratory distress syndrome patients. The grant is expected to provide up to approximately 
£2.0 million (approximately $3.1 million based on the current exchange rate) in support over the course of the study, which will be 
conducted at leading clinical sites in the United Kingdom in conjunction with the Cell Therapy Catapult, a not-for-profit center 
focused on the development of the United Kingdom cell therapy industry.

ITEM 11. EXECUTIVE COMPENSATION 

Compensation Discussion and Analysis  

Executive Summary  

This section discusses the principles underlying our executive compensation policies and decisions and the most important 
factors relevant to an analysis of these policies and decisions. It provides qualitative information regarding the manner and context in 
which compensation is awarded to and earned by our named executive officers, which include Dr. Gil Van Bokkelen, our Chief 
Executive Officer, Ms. Laura Campbell, our Vice President of Finance, Mr. William (B.J.) Lehmann, Jr., our President and Chief 
Operating Officer, Dr. John Harrington, our Executive Vice President and Chief Scientific Officer, and Dr. Robert Deans, our 
Executive Vice President of Regenerative Medicine, and places in perspective the data presented in the compensation tables and 
narratives that follow.  

We are an international biotechnology company that is focused primarily in the field of regenerative medicine. Our MultiStem 

cell therapy has been evaluated in two completed Phase 1 clinical trials and is currently being evaluated in two ongoing Phase 2 
clinical trials, as well as an investigator-led Phase 1 trial. We are also applying our pharmaceutical discovery capabilities to identify 
and develop small molecule compounds with potential applications in indications such as obesity, related metabolic conditions and 
certain neurological conditions. These represent major areas of clinical need, as well as substantial commercial opportunities. As 
further discussed in this section, our compensation and benefit programs help us attract, retain and motivate individuals who will 
maximize our business results by working to meet or exceed established company or individual objectives. In addition, we reward our 
executive officers for meeting certain developmental milestones, such as completing advancements in product candidate 
development, strategic partnerships or other financial transactions that add to the capital resources of the Company or create value for 
stockholders.  

68

  
  
The following are the highlights of our 2014 compensation and benefit programs: 

•

•

•

  increased the base salaries of our named executive officers; 

  paid cash bonuses to our named executive officers; and 

  granted stock options and restricted stock unit awards to our named executive officers under our annual equity 

compensation program. 

The following discussion and analysis of our compensation and benefit programs for 2014 should be read together with the 

compensation tables and related disclosures that follow this section. This discussion includes forward-looking statements based on 
our current plans, considerations, expectations and determinations about our compensation program. Actual compensation decisions 
that we may make for 2015 and beyond may differ materially from our recent past.  

Compensation Objectives and Philosophy  

Our executive compensation programs are designed to:  

•

•

•

•

  recruit, retain, and motivate executives and employees that can help us achieve our core business goals; 

  provide incentives to promote and reward superior performance throughout the organization, which we refer to as 

Pay for Performance; 

  facilitate stock ownership and retention by our executives and other employees; and 

  promote alignment between executives and other employees and the long-term interests of stockholders. 

The Compensation Committee seeks to achieve these objectives by:  

•

•

•

  establishing a compensation program that is market competitive and internally fair; 

  linking individual and corporate performance with certain elements of compensation through the use of equity 

grants, cash performance bonuses or other means of compensation, the value of which is substantially tied to the 
achievement of our Company goals; and 

  when appropriate, given the nature of our business, rewarding our executive officers for both Company and 

individual achievements with one-time performance awards. 

At the 2014 Annual Meeting of Stockholders, approximately 82% of the votes cast were voted in favor of the approval of our 
named executive officer compensation. Our Compensation Committee believes that the stockholder vote reinforces the objectives and 
philosophy of our executive compensation programs.  

Components of Compensation  

Our executive compensation program includes the following elements:  

•

•

•

•

  base salary; 

  cash bonuses; 

  long-term equity incentive plan awards; and 

  retirement and health and other insurance benefits. 

Our Compensation Committee has not adopted any formal or informal policies or guidelines for allocating compensation 
between long-term and currently paid-out compensation, between cash and non-cash compensation or among different forms of non-
cash compensation. We consider competitive practices, relative management level and operating responsibilities of each executive 
officer when determining the compensation elements to reward his or her ability to impact short-term and long-term results.

Role of the Chief Executive Officer 

Historically, our Chief Executive Officer has taken the lead in providing our Board of Directors with advice regarding executive 
compensation. For 2014, the Compensation Committee considered recommendations from our Chief Executive Officer regarding the 
compensation for and performance of our executive officers in relation to company-specific strategic goals that were established by 
the Compensation Committee and approved by the Board of Directors. These achievements related to potential bonus payments and 
salary increases. The Compensation Committee considers the recommendations made by our Chief Executive Officer because of his 
knowledge of the business and the performance of the other executive officers. The Compensation Committee is not bound by the 
input it receives from our Chief Executive Officer. Instead, the Compensation Committee exercises independent discretion when 
making executive compensation decisions. We describe and discuss the particular compensation decisions made by the Compensation 
Committee regarding the 2014 compensation of our named executive officers below under “Elements of Executive Compensation.”  

Role of the Independent Compensation Consultant  

From time to time, the Compensation Committee has retained the services of an independent compensation consultant, Arnosti 

Consulting, Inc., or Arnosti. During 2014, at the request of the Compensation Committee, Arnosti assisted the Compensation 
Committee in evaluating the base salaries to be paid to named executive officers and the annual equity awards to be granted 
companywide. The Company pays the cost for Arnosti’s services. However, the Compensation Committee retains the sole authority 
to direct, terminate or engage Arnosti’s services. In 2014, the Compensation Committee considered and assessed all relevant factors, 
including but not limited to, those set forth in Rule 10C-1(b)(4)(i) through (vi) under the Exchange Act, that could give rise to a 
potential conflict of interest with respect to Arnosti’s work. Based on this review, we are not aware of any conflict of interest that has 
been raised by the work performed by Arnosti.  

Elements of Executive Compensation  

Base Salary. We pay base salaries to provide executive officers with a competitive level of financial security. We establish base 
salaries for our executives based on the scope of their responsibilities, taking into account competitive market compensation paid by 
other companies for similar positions. Base salaries are generally reviewed annually, with adjustments based on the individual’s 
responsibilities, performance and experience during the year. This review generally occurs each year following an annual review of 
individual performance.  

In general, the Company and the executive team performed well in 2014 against many key goals and objectives, as measured 

against the metrics of key programmatic achievements (e.g., clinical, preclinical and core capability development), business 
development objectives, operational and financial performance (e.g., budgetary goals, capital acquisition and management), and 
intellectual property (e.g., patent issuances and new filings, competitive positioning), among others. Each executive’s performance 
was evaluated based on the Company’s performance as a whole, combined with an evaluation of individual performance against 
specific goals and objectives relevant to his or her area of responsibility. Overall, nearly half of corporate goals were achieved in 
2014, taking into account that a business partnership was not achieved, which was, and continues to be, an important goal.  

For 2014, the Compensation Committee and the Board of Directors approved an increase in base salary of 2.00% for 2014 as 

compared to 2013 for the Chief Executive Officer, an adjustment based on both performance and comparative market data provided 
to the Compensation Committee by Arnosti. Also for 2014, the Compensation Committee and the Board of Directors approved 
increases for each of the other named executive officer’s salary for 2014 as compared to 2013 based primarily on Company 
performance for the year ended December 31, 2013. The increases were as follows: Mr. Lehmann – 2.05%; Dr. Harrington – 2.06%; 
Dr. Deans – 2.04%; and Ms. Campbell – 2.07%.  

For 2015, the Compensation Committee and the Board of Directors approved an increase in base salary of 1.75% for 2015 as 

compared to 2014 for the Chief Executive Officer, an adjustment based on both performance and comparative market data provided 
to the Compensation Committee by Arnosti. Also for 2015, the Compensation Committee and the Board of Directors approved 
increases for each of the other named executive officer’s salary for 2015 as compared to 2014 based primarily on Company 
performance for the year ended December 31, 2014. The increases are as follows: Mr. Lehmann – 1.83%; Dr. Harrington – 1.84%; 
Dr. Deans – 1.66%; and Ms. Campbell – 1.81%.  

70

  
Cash Bonuses. Given the nature of our business, when appropriate, we reward our named executive officers with performance-
related bonuses. We utilize annual incentive bonuses to reward officers and other employees for achieving corporate objectives and 
for individual annual performance objectives. These objectives relate generally to strategic factors, including advancement of our 
product candidates, identification and advancement of additional programs or product candidates, establishment and maintenance of 
key strategic relationships, and to financial factors, including raising capital, adherence to budgets and cash management.  

The Compensation Committee recommended and the Board approved a cash bonus incentive program for the year ended 
December 31, 2014 for our named executive officers. Under the 2014 incentive program, each participant was eligible to earn a target 
bonus of a specified percentage of the named executive officer’s salary during the award term, weighted on the achievement of 
specific corporate goals, with the remainder based on individual/functional performance, as set forth below:  

Dr. Van Bokkelen

The evaluation of goal achievement is at the discretion of Compensation Committee and Board of Directors based on input from 
the Chief Executive Officer (with respect to the named executive officers other than the Chief Executive Officer). The 2014 corporate 
goals included program and collaboration goals, including new business development, progress on MultiStem clinical development 
and cash management objectives. However, any bonus ultimately paid under our annual incentive program is at the discretion of the 
Board of Directors based on the recommendation of the Compensation Committee, after good faith consideration of executive officer 
performance, overall company performance, market conditions and cash availability. We do not have a formally adopted plan 
document for the 2014 incentive program, although the Compensation Committee recommended and the Board of Directors approved 
the specific corporate goals, target bonus levels and weightings between corporate and functional performance. The Compensation 
Committee and the Board of Directors agreed that each of the named executive officers would be entitled to a bonus under the 2014 
incentive program as a result of individual performance and the achievement of operational and strategic objectives in 2014, 
specifically the achievement of patient enrollment and regulatory approval goals for the Company’s clinical studies, capital 
management and the receipt of new grant funding, and other core program development and sector leadership goals, resulting in the 
payment of bonuses based on a percentage of such officers’ 2014 base salaries as follows:

For the year ending December 31, 2015, the Compensation Committee recommended and the Board of Directors approved a 
similar cash bonus incentive plan for our named executive officers, with no changes to the target bonus percentage for our named 
executive officers from 2014.  

The 2015 corporate goals include strategic partnership objectives, advancing and achieving clinical development and related 

support activities for MultiStem, program advancement objectives, and executing against the established operating plan and capital 
acquisition objectives.  

Long-Term Incentive Program. We believe that we can encourage superior long-term performance by our executive officers and 
employees through encouraging them to own, and assisting them with the acquisition of, our common stock. Our equity compensation 
plans provide our employees, including named executive officers, with incentives to help align their interests with the interests of our 
stockholders. We believe that the use of common stock and stock-based awards offers the best approach to achieving our objective of 
fostering a culture of ownership, which we believe will, in turn, motivate our named executive officers to create and enhance 
stockholder value. We have not adopted stock ownership guidelines, but our equity compensation plans provide a principal method 
for our executive officers to acquire equity in our company.

Our equity compensation plans authorize us to grant, among other types of awards, options, restricted stock and restricted stock 

units, or RSUs, to our employees, Directors and consultants. Historically, we elected to use stock options as our primary long-term 
equity incentive vehicle. However, we began awarding RSUs to our non-executive employees in 2011 and to our named executive 
officers in 2013. We expect to continue to use equity-based awards as a long-term incentive vehicle because we believe:  

•   equity-based awards align the interests of our executives with those of our stockholders, support a pay-for-performance 

culture, foster an employee stock ownership culture and focus the management team on increasing value for our stockholders; 

•   equity-based awards have the potential to increase in value based on our performance and the growth of our stock price; 

•   equity-based awards help to provide a balance to the overall executive compensation program because, while base salary and 
our discretionary annual bonus program focus on short-term performance, vesting equity-based awards reward increases in 
stockholder value over the longer term; and 

•   the vesting period of equity-based awards encourages executive retention and efforts to preserve stockholder value. 

In 2014, we granted 657,664 stock options and 292,352 RSUs to our named executive officers, as well as stock options and 

RSUs to our other employees. We revised our long-term equity incentive program for our named executive officers in 2013 in 
connection with the termination of an outdated incentive program and the initiation of an ordinary-course annual equity award 
program.  

Annual equity awards are tied to factors such as performance, peer and market analysis, and total equity ownership level of each 
named executive officer, and further enhance the retention and long-term stock ownership features of our equity incentive program. In 
determining the number of stock-based awards to be granted to named executive officers, we review annually our named executive 
officers’ equity ownership positions, and we take into account the individual’s scope of responsibility, ability to affect results and 
stockholder value, anticipated future contributions to increases in shareholder value, and the value of equity-based awards in relation 
to other elements of the individual named executive officer’s total compensation. We also review competitive compensation data, an 
assessment of individual performance, a review of each named executive officer’s existing long-term incentives, retention 
considerations and a subjective determination of the individual’s potential to positively impact future stockholder value. Equity-based 
awards are granted from time to time by the Compensation Committee and the Board of Directors, with input from independent 
compensation consultants, as appropriate. The following stock option and RSU awards were granted to our named executive officers 
in June 2014 as part of our program for annual equity-based awards, which vest quarterly over a four-year period:

Retirement and Insurance Benefits. Consistent with our compensation philosophy, we maintain benefits for our named executive 

officers, including medical, dental, vision, life and disability insurance coverage and the ability to contribute to a 401(k) retirement 
plan. The named executive officers and employees have the ability to participate in these benefits at the same levels. We make 
employer contributions to our 401(k) retirement plan and contributed approximately $285,000 in 2014. We provide such retirement 
and health insurance benefits to our employees to retain qualified personnel.  

In addition, Dr. Van Bokkelen, Dr. Harrington, Mr. Lehmann, Dr. Deans and Ms. Campbell also receive Company-paid life 

insurance benefits in the amounts of $2.0 million for Dr. Van Bokkelen, Dr. Harrington and Mr. Lehmann, and $1.0 million for 
Dr. Deans and Ms. Campbell. These additional life insurance policies are provided to these officers due to their extensive travel 
requirements and contributions to the Company.  

Severance Arrangements  

See the disclosure under “Potential Payments Upon Termination or Change of Control” for more information about severance 

arrangements with our named executive officers. We provide such severance arrangements in order to assure that our executives will 
focus on the best interests of the business at all times, without undue concern for their own financial security.

Employment Agreements and Arrangements  

We believe that entering into employment agreements with each of our named executive officers was necessary for us to attract 

and retain talented and experienced individuals for our senior level positions. In this way, the employment agreements help us meet 
the initial objective of our compensation program. Each agreement contains terms and arrangements that we agreed to through arms-
length negotiation with our named executive officers. We view these employment agreements as reflecting the minimum level of 
compensation that our named executive officers require to remain employed with us, and thus the bedrock of our compensation 
program for our named executive officers. For more details of our employment agreements and arrangements, see the disclosure 
under “2014 Summary Compensation Table.”  

General Tax Deductibility of Executive Compensation  

We structure our compensation program to comply with Internal Revenue Code Section 162(m). Under Section 162(m) of the 

Code, there is a limitation on tax deductions of any publicly-held corporation for individual compensation to certain executives of 
such corporation exceeding $1.0 million in any taxable year, unless the compensation is performance-based. The Compensation 
Committee manages our incentive programs to qualify for the performance-based exemption; however, it also reserves the right to 
provide compensation that does not meet the exemption criteria if, in its sole discretion, it determines that doing so advances our 
business objectives.

(1) The target bonuses as a percentage of salary were increased in 2014. 
(2) Amounts do not reflect cash compensation actually received by our named executive officers. The amounts for annual stock 

(3)

awards that began in 2014 for our named executive officers represent the grant date full value of restricted stock units that vest 
over a four-year period. The fair value of restricted stock unit awards is calculated in accordance with Accounting Standards 
Codification 718 (“ASC 718”), excluding the impact of potential forfeitures. Assumptions used in the calculation of these 
amounts are included in the Notes to the audited consolidated financial statements included herein for the fiscal year ended 
December 31, 2014. 
In 2005, in connection with a restructuring of internal programs and to retain and motivate executives, Athersys entered into 
incentive agreements that provided the executives financial participation in the event of certain merger or acquisition or asset 
sale transactions. The agreements were established prior to our common stock being publicly traded, had precluded the granting 
of routine equity awards to officers, and had become outdated. In 2013, the Board approved arrangements whereby the officers 
agreed to terminate their incentive agreements in return for one-time grants of RSUs for their past service and performance and 
the ability to receive routine annual grants of equity-based awards, to better align management incentives with corporate 
objectives. The amounts for these 2013 stock awards represent the grant date full value of the RSUs that vest over a three-year 
period. The fair value of RSUs is calculated in accordance with ASC 718, excluding the impact of potential forfeitures. 
Assumptions used in the calculation of these amounts are included in the Notes to the audited consolidated financial statements 
included herein for the fiscal year ended December 31, 2014. 

(4) Amounts do not reflect cash compensation actually received by our named executive officers. The amounts for option awards 

reflect the full grant date fair value of the equity awards made during the fiscal years ended December 31, 2014 and 2013 in 
accordance with ASC 718, excluding the impact of potential forfeitures. Assumptions used in the calculation of these amounts 
are included in the Notes to the audited consolidated financial statements included herein for the fiscal year ended December 31, 
2014. 

(5) Total column includes salary, bonus and non-cash compensation related to stock-based awards. For example, Dr. Van Bokkelen 

salary was $450,000 in 2013, but the $2,034,488 total includes non-cash compensation related to a stock-based award that was 
received in 2013 tied to the termination of an incentive agreement. See Note 3 above. 

(6) Drs. Van Bokkelen and Harrington also served as our Directors for 2014, 2013 and 2012 but did not receive any compensation 

as our Directors.

Dr. Deans has also entered into a non-competition and confidentiality agreement with us under which, during his employment and for 
a period of six months thereafter, he is restricted from, among other things, competing with us.  

Equity Compensation Plans  

In June 2007, we adopted two equity compensation plans, which authorize the Board of Directors, or a committee thereof, to 
provide equity-based compensation in the form of stock options, restricted stock, RSUs and other stock-based awards, which are used 
to attract and retain qualified employees, Directors and consultants. Equity awards are granted from time to time under the guidance 
and approval of the Compensation Committee. Total awards under these plans, as amended, are currently limited to 11,500,000 shares 
of common stock, of which 1,630,859 shares remain available for issuance at December 31, 2014.  

401(k) Plan  

We have a tax-qualified employee savings and retirement plan, also known as a 401(k) plan that covers all of our employees. 
Under our 401(k) plan, eligible employees may elect to reduce their current compensation by up to the statutorily prescribed annual 
limit, which was $17,500 in 2014, and have the amount of the reduction contributed to the 401(k) plan. The trustees of the 401(k) 
plan, at the direction of each participant, invest the assets of the 401(k) plan in designated investment options. We may make 
matching or profit-sharing contributions to the 401(k) plan in amounts to be determined by the Board of Directors. We made 
matching contributions to the 401(k) plan during fiscal 2014 at a maximum rate of 100% of the first $3,000 of participant 
contributions, plus 40% of participant contributions in excess of $3,000 per participant, which amounted to approximately $284,000 
in 2014. The 401(k) plan is intended to qualify under Section 401 of the Internal Revenue Code, so that contributions to the 401(k) 
plan and income earned on the 401(k) plan contributions are not taxable until withdrawn, and so that any contributions we make will 
be deductible when made.

(1) The value realized upon vesting is the product of multiplying the number of shares of common stock by the market value of the 

underlying shares on the vesting date. 

Potential Payments Upon Termination or Change in Control  

Under their employment agreements, the named executive officers may be entitled to certain potential payments upon 

termination. In the event that an executive officer is terminated without cause or terminates employment for good reason, as defined 
in the agreements, we would be obligated to pay full base salary for a defined period, subject to mitigation related to other 
employment. For Gil Van Bokkelen and John Harrington, the defined payment period is 18 months, for William (BJ) Lehmann, the 
defined payment period is twelve months, and for Laura Campbell and Robert Deans, the defined payment period is six months. We 
would also be obligated to continue the participation of Gil Van Bokkelen and John Harrington in all other medical, life and employee 
“welfare” benefit programs for a period of eighteen months at our expense, to the extent available and possible under the programs.  

The agreements define “cause” to mean willful and continuous neglect of such executive officer’s duties or responsibilities or 
willful misconduct by the executive officer that is materially and manifestly injurious to Athersys. “Good reason” includes, among 
other things, demotion, salary reduction, relocation, failure to provide an executive officer with adequate and appropriate facilities 
and termination by the executive officer within 90 days of a change in control. A “change in control” occurs when (1) a person or 
group of persons purchases 50% or more of our consolidated assets or a majority of our voting shares, or (2) if, following a public 
offering, the directors of Athersys immediately following the offering no longer constitute a majority of the Board of Directors. Upon 
a change in control, or if the named executive officer should die or become permanently disabled, all unvested stock options become 
immediately vested and exercisable. As of December 31, 2014, each of the named executive officers held unvested stock options and 
RSUs, as reflected in the Outstanding Equity Awards at 2014 Fiscal Year-End table above.  

In the event that an executive officer is terminated for cause or as a result of death, we would be obligated to pay full base salary 

and other benefits, including any unpaid expense reimbursements, through the date of termination, and would have no further 
obligations to the executive officer. In the event that an executive officer is unable to perform duties as a result of a disability, we 
would be obligated to pay full base salary and other benefits until employment is terminated and for a period of twelve months from 
the date of such termination.  

The table below reflects the amount of compensation payable to each named executive officer in the event of termination of 

such executive’s employment, pursuant to such executive’s employment agreement. The amounts shown assume that such 
termination was effective as of December 31, 2014 and thus includes amounts earned through such time and are estimates of the 
amounts that would be paid out to executives upon their termination.

(1) Amounts in column (d) do not necessarily reflect compensation actually received by our Directors. The amounts in column 
(d) reflect the full grant date fair value of the equity awards made during the fiscal year ended December 31, 2014, in 
accordance with ASC 718. Assumptions used in the calculation of these amounts are included in the notes to the 2014 audited 
consolidated financial statements included herein. The Directors had option awards outstanding as of December 31, 2014 for 
shares of common stock as follows: Lee Babiss — 165,000; Ismail Kola 165,000; Lorin Randall — 105,000; Kenneth Traub — 
90,000; and Jack Wyszomierski — 165,000. 

Under our Director compensation program for non-employee Directors, new Directors receive an initial stock option grant to 
purchase 50,000 shares of Common Stock at fair market value on the date of grant, which vests at a rate of 50% in the first year (on a 
quarterly basis) and 25% in each of the two years (on a quarterly basis) thereafter.  

Additionally, the non-employee Directors receive annually an option award to purchase 30,000 shares of common stock at fair 
market value on the date of grant, which vests quarterly over a one-year period, with such anniversary awards issued in June of each 
year in connection with our annual stockholder meeting. In June 2014, Directors Babiss, Kola, Randall, Traub and Wyszomierski 
each received an anniversary stock option award of 30,000 shares. All initial and anniversary stock option awards granted to non-
employee Directors have a term of ten years and upon the termination of the Director’s service, the Director has 18 months in which 
to exercise the vested portion of his options prior to forfeiture.

Compensation Committee Interlocks and Insider Participation

construed to constitute a committee interlock within the meaning of the rules of the SEC.  

Compensation Committee Report  

The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis section

(3) The other shares of common stock included in this plan category are issued or issuable under our Equity Incentive 

Compensation Plan. The terms of our Equity Incentive Compensation Plan are substantially similar to the terms of the Current 
LTIP. For information on the terms of these plans, see “Compensation Discussion and Analysis – Elements of Executive 
Compensation – Long-Term Incentive Program”, as well as “Compensation Discussion and Analysis – Equity Compensation 
Plans” in this annual report on Form 10-K. 

BENEFICIAL OWNERSHIP OF COMMON STOCK  

The following table sets forth certain information known to us regarding the beneficial ownership of our common stock as of 

February 28, 2015 (unless otherwise indicated below) by:  

•   each person known by us to beneficially own more than 5% of our common stock; 

•   each of our Directors; 

•   each of the executive officers named in the Summary Compensation Table; and 

•   all of our Directors and executive officers as a group. 

We determined beneficial ownership in accordance with the rules of the SEC. In computing the number of shares beneficially 
owned by a person and the percentage ownership of that person, shares of common stock that could be issued upon the exercise of 
outstanding options, RSUs and warrants held by that person that are exercisable within 60 days of February 28, 2015 are considered 
outstanding. These shares, however, are not considered outstanding when computing the percentage ownership of each other person.  

Percentage ownership calculations for beneficial ownership for each person or entity are based on 79,937,970 shares of common 

stock outstanding as of February 28, 2015.  

Except as indicated in the footnotes to this table and pursuant to state community property laws, each stockholder named in the 

table has sole voting and investment power for the shares shown as beneficially owned by them.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE 

Certain Relationships and Related Person Transactions  

We give careful attention to related person transactions because they may present the potential for conflicts of interest. We refer 

to “related person transactions” as those transactions, arrangements, or relationships in which:  

•   we were, are or are to be a participant; 

•   the amount involved exceeds $120,000; and 

•   any of our Directors, Director nominees, executive officers or greater-than five percent stockholders (or any of their 

immediate family members) had or will have a direct or indirect material interest. 

To identify related person transactions in advance, we rely on information supplied by our executive officers, Directors and 
certain significant stockholders. We maintain a comprehensive written policy for the review, approval or ratification of related person 
transactions, and our Audit Committee reviews all related person transactions identified by us. The Audit Committee approves or 
ratifies only those related person transactions that are determined by it to be, under all of the circumstances, in the best interest of the 
Company and its stockholders. No related person transactions occurred in fiscal 2014 that required a review by the Audit Committee. 

At times, Aspire Capital has beneficially owned more than 5% of our outstanding common stock. We entered into an equity 
purchase agreement with Aspire Capital in 2011, which provided that Aspire Capital was committed to purchase up to an aggregate of 
$20.0 million of shares of our common stock over a two-year term, subject to our election to sell any such shares. Under the 
agreement, we had the right to sell shares, subject to certain volume limitations and a minimum floor price, at a modest discount to 
the prevailing market price. As part of the agreement, Aspire Capital made an initial investment of $1.0 million in us through the 
purchase of 666,667 shares of our common stock at $1.50 per share in 2011, and received 266,667 additional shares as compensation 
for its commitment. As a result of this transaction, combined with shares of our common stock that Aspire Capital held prior to the 
November 2011 transaction, Aspire Capital became one of our larger stockholders, owning more than 5% of our shares of our 
common stock outstanding at that time.  

By September 2013, we had sold all the remaining shares that were available under the 8,000,000 shares of common stock 
registered for resale under the equity facility, which was due to expire in January 2014. In October 2013, we terminated the expiring 
equity purchase agreement with Aspire Capital and entered into a new equity purchase agreement with Aspire Capital to purchase up 
to an aggregate of $25.0 million of shares of our common stock over a new two-year period. The terms of the 2013 equity facility are 
similar to the previous arrangement, and we issued 333,333 shares of our common stock Aspire Capital as a commitment fee in 
October 2013 and filed a registration statement for the resale of 10,000,000 shares of common stock in connection with the new 
equity facility.  

In 2014, we sold an aggregate 250,000 shares to Aspire Capital at an average price of $3.78 per share under the equity purchase 

agreement. As of December 31, 2014, we received aggregate proceeds of approximately $14.4 million under both equity purchase 
agreements since their inception. Also, since January 1, 2015 through March 9, 2015, we sold shares for approximately $3.3 million, 
in aggregate, to Aspire Capital.

Director Independence  

The Board reviews the independence of each Director at least annually. During these reviews, the Board will consider 
transactions and relationships between each Director (and his or her immediate family and affiliates) and the Company and our 
management to determine whether any such transactions or relationships are inconsistent with a determination that the Director was 
independent. The Board conducted its annual review of Director independence to determine if any transactions or relationships exist 
that would disqualify any of the individuals who serve as a Director under the rules of the NASDAQ Capital Market or require 
disclosure under Securities and Exchange Commission, or SEC, rules. Based upon the foregoing review, the Board determined the 
following individuals are independent under the rules of the NASDAQ Capital Market: Lee E. Babiss, Ismail Kola, Lorin J. Randall, 
Kenneth H. Traub and Jack L. Wyszomierski. Currently, we have two members of management that also serve on the Board: Dr. Van 
Bokkelen, who is also our Chairman and Chief Executive Officer, and Dr. Harrington, who is our Executive Vice President and Chief 
Scientific Officer. Neither Dr. Van Bokkelen nor Dr. Harrington is considered independent under the independence rules of the 
NASDAQ Capital Market.  

ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES

Audit Committee Pre-Approval Policies and Procedures

of all professional services rendered by the Company’s independent auditor prior to the commencement of the specified services.  

For the fiscal year ended December 31, 2014, 100% of the services described above were pre-approved by the Audit Committee 

in accordance with the Company’s formal policy on auditor independence.
