XENON PHARMACEUTICALS INC. 

2016 ANNUAL REPORT 

  
  
  
 
To Our Shareholders: 

In 2016, we advanced our pipeline, supported our partnerships, moved our proprietary programs 
forward, and strengthened our financial position, while continuing to operate in a capital-efficient 
manner. 

We have built a business model that includes proprietary as well as partnered programs, which has 
enabled the advancement of a diversified pipeline of product candidates. Our strategy provides us 
with multiple “shots on goal” emerging from our expertise in ion channelopathies as well as in 
human genetics, which we believe enables us to select novel targets with high human relevance and 
develop highly selective and differentiated modulators of these targets. 

Update on Our Proprietary Pipeline  

In March 2017, we announced that the topline data from our XEN801 Phase 2 trial for the treatment 
of moderate to severe acne did not meet its primary or secondary efficacy endpoints, and that the 
results did not support the continued development of XEN801. While it is always a disappointment 
when a clinical program does not move forward, given the breadth of our pipeline and the promising 
potential of our ion channel and neurology expertise, we are focused on advancing our proprietary 
and partnered ion channel modulator neurology programs and adding new product candidates into 
our development pipeline. 

We are excited to have identified XEN901, which is a potent, selective Nav1.6 inhibitor for the 
treatment of rare infantile epileptic encephalopathies and other forms of epilepsy. The Nav1.6 
sodium channel is a sub-type from a class of targets that appear to play a key role in balancing neuro-
excitation and neuro-inhibition in the central nervous system. Nav1.6 is the most highly expressed 
sodium channel in the hyperexcitatory pathways in the brain. Gain-of-function mutations in Nav1.6 
cause a severe form of early onset epilepsy. XEN901 has demonstrated efficacy against seizures in a 
preclinical animal model of Nav1.6 gain-of-function epilepsy as well as models that support the 
potential treatment of adult partial onset epilepsy. We expect to file an IND, or IND equivalent, in 
the fourth quarter of this year. 

Update on Our Partnered Pain Programs  

There is a critical medical need for non-opioid pain medications. Our collaborations with Teva and 
Genentech are focused on developing novel inhibitors of another sodium channel, Nav1.7, for the 
treatment of pain. With a tremendous amount of human genetic data, Nav1.7 is considered to be an 
important pain-related target. We are fortunate to have two promising partnerships focused on 
innovative pain treatments.  

We are collaborating with Teva on developing a topical sodium channel blocker (TV-45070) for 
peripheral application to treat post-herpetic neuralgia, or PHN. TV-45070 targets Nav1.7 as well as 
other sodium channels in the peripheral nervous system to treat conditions of chronic pain. Teva is 
conducting a randomized, double-blind, placebo-controlled Phase 2b clinical trial of TV-45070 in 
patients with PHN, with topline results expected in mid-2017. 

In our collaboration with Genentech, we are focused on developing an orally active, highly selective 
small molecule inhibitor of Nav1.7 for the treatment of pain (GDC-0310). Genentech has completed 
a Phase 1 clinical trial for GDC-0310. Pending the results of ongoing preclinical work, Genentech 
has guided that it anticipates initiating a Phase 2 clinical trial in 2017. 

We have a strong interest in expanding our pipeline of neurology assets to add to our three ion 
channel modulators in development (XEN901, GDC-310, and TV-45070). This future pipeline 
expansion could come either from our own internal research efforts or through the in-licensing or 
acquisition of other product candidates that represent a good strategic fit with our neurology ion 
channel focus. We anticipate presenting new development stage programs in the coming months as 
these ongoing product assessments come to fruition.  

Looking Forward 

We believe that 2017 presents us with multiple potential value inflection points, including the TV-
45070 Phase 2b clinical trial topline results; the advancement of GDC-0310 into a Phase 2 clinical 
trial; the filing of an IND or IND equivalent for our XEN901 program; and the potential 
opportunities to further expand our proprietary pipeline with novel ion channel modulators. Each of 
these key events has the potential to have a meaningful impact on our company.  

We ended 2016 with no debt and approximately $64.1 million in cash and cash equivalents. With our 
strong balance sheet, and the potential for $32.5 million in potential milestone payments over the 
next 24 months from our partnered collaborations, we believe that we are well supported to achieve 
our near-term goals. 

We wish to thank our Board and employees for their contributions to our growth, and, as always, we 
appreciate the continued support of our shareholders. We remain excited about the multiple 
milestone opportunities from our ion channel pipeline anticipated in the remainder of 2017.

Item 1. 

Business 

Overview 

We are a clinical-stage biopharmaceutical company discovering and developing a pipeline of differentiated therapeutics for 
orphan indications that we intend to commercialize on our own, and for larger market indications that we intend to partner with global 
pharmaceutical companies. We have expertise in human genetics, small molecule drug discovery, as well as preclinical and clinical 
development that we intend to leverage to develop innovative therapeutics, including novel selective ion channel inhibitors.  

Our pharmaceutical partners include Teva Pharmaceutical Industries, Ltd., or Teva (through its subsidiary, Ivax International 
GmbH), Genentech, a member of the Roche Group, and Merck & Co., Inc., or Merck (through its affiliate, Essex Chemie AG). Our 
pharmaceutical collaborations have generated in aggregate over $160.0 million in non-equity funding to date with the potential to 
provide us with over $1.0 billion in future milestone payments, as well as royalties and co-promotion income on product sales. 

Our proprietary development pipeline and pharmaceutical partnerships include: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

XEN801 is a stearoyl Co-A desaturase-1, or SCD1, inhibitor being developed for the treatment of acne. SCD1 is an 
enzyme involved in lipid synthesis that is expressed in sebaceous glands in the skin. We have completed enrollment in a 
Phase 2 clinical trial in patients with moderate to severe facial acne, and anticipate topline results in the latter part of the 
first quarter of 2017; 

XEN901 is a potent, selective Nav1.6 inhibitor being developed for the treatment of rare infantile epileptic 
encephalopathies and other forms of epilepsy. We expect to file an investigational new drug, or IND, or an IND 
equivalent application in the fourth quarter of 2017; 

Our collaborator Teva is developing TV-45070, which is a topical sodium channel inhibitor for the treatment of 
neuropathic pain. Teva is currently conducting a randomized, double-blind, placebo-controlled Phase 2b clinical trial of 
TV-45070 in patients with post-herpetic neuralgia, or PHN, with topline results expected in mid-2017;  

Our collaborator Genentech has completed two Phase 1 clinical trials for GDC-0276 and GDC-0310, which are both oral, 
selective Nav1.7 small-molecule inhibitors. Genentech has indicated that it intends to focus its ongoing development 
efforts on GDC-0310. Pending a full assessment of the Phase 1 clinical results and ongoing in vivo studies, Genentech 
anticipates initiating a Phase 2 clinical trial in 2017 for the potential treatment of pain; and 

Our licensee uniQure Biopharma B.V., or uniQure, has developed Glybera for the treatment of the orphan disorder 
lipoprotein lipase deficiency, or LPLD. Glybera was the first gene therapy product approved in the European Union, or 
the EU. In November 2015, the first patient treated with Glybera as a commercially available gene therapy was announced 
by uniQure and enabled by its commercialization partner in the EU, Chiesi Farmaceutici S.p.A., or Chiesi, which has sole 
control over commercialization in the EU.  

Our Strategy  

Our goal is to build a self-sustaining, fully-integrated and profitable company that discovers, develops and commercializes 

innovative therapeutics, including novel selective ion channel inhibitors, by leveraging our expertise in the genetics of rare human 
diseases. 

3 

 
Since our inception, we believe we have operated in a capital-efficient manner to build our capabilities and assets through 

phased growth, expansion and value creation. Prior to our November 2014 initial public offering and concurrent private placement, 
our last equity financing was in 2006. From 2006 to November 2014, we funded our operations and expanded our platform, product 
pipeline and infrastructure through a strategy which combined the deployment of our own resources and the establishment of broadly 
enabling and well-structured pharmaceutical partnerships with industry leaders. In September 2016, we successfully completed an 
underwritten public offering of 3,450,000 common shares at a public offering price of $7.50 per common share, resulting in 
approximately $24.3 million of proceeds to us, net of underwriting discounts and commissions but before offering expenses. 

Our strategy includes: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

Expanding our pipeline and advancing multiple discovery and development programs, either from our internal research 
efforts or through acquiring or in-licensing other product candidates or technologies;  

Focusing on orphan and niche disease market opportunities that we can independently develop and commercialize 
ourselves.  

Selectively establishing additional partnerships enabling us to access large commercial indications while leveraging the 
benefits of those collaborations to expand our internal capabilities.  

Further leveraging our discovery platform and insights into disease biology to identify novel targets and develop next-
generation products. 

Our Extreme Genetics Discovery Platform 

Our business was founded on our proprietary discovery platform, which we refer to as Extreme Genetics, for the discovery of 
validated drug targets by studying rare human diseases with extreme traits, including diseases caused by mutations in ion channels, 
known as channelopathies. Extreme Genetics involves the study of families where individuals exhibit inherited severe traits, or 
phenotypes. By identifying and characterizing single-gene defects responsible for these phenotypes, we gain insights into human 
disease biology to better select targets for therapeutic intervention. Our Extreme Genetics discovery platform yielded the first 
approved gene therapy product in the EU. 

The key components of our Extreme Genetics discovery platform include: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

clinical geneticists and genetic counselors with a deep understanding of clinical phenotypes. These experts identify the 
rare genetic disorders with severe phenotypes that we study; 

years of experience and extensive know-how in successfully navigating through regulations in multiple countries in order 
to obtain the approvals necessary to collect and use detailed clinical information and DNA samples from individuals and 
families with severe phenotypes; 

internal capabilities in genome sequencing, molecular biology and bioinformatics to enable identification of single-gene 
defects and validation of these as potential drug targets;  

expertise in small-molecule drug discovery to design promising product candidates that effectively modulate the identified 
drug targets. Our drug discovery capabilities include medicinal and synthetic chemistry, assay development and in vitro 
and in vivo pharmacology; and 

an established global network of clinical collaborators in multiple countries, which has provided us with access to rare 
individuals and families with severe phenotypes dispersed throughout the world. 

In addition, we have built upon our global network by developing a new direct-to-patient web-based recruitment approach for 
identifying patients with rare or extreme phenotypes. By leveraging social media tools and allowing potential participants to directly 
access research studies online, we have successfully broadened the recruitment of participants for several of our research studies.  

Focus on Human Channelopathies 

A significant focus of our Extreme Genetics discovery platform has been on human channelopathies, enabling us to develop 

strong capabilities in small molecule ion channel drug discovery. Our ion channel discovery capability is founded upon our 
understanding of the genetics of channelopathies combined with our proprietary biology and medicinal chemistry assets and know-
how. With our collaborators, we identified new binding sites on ion channels which, in turn, led to the discovery of highly-selective 
voltage-gated ion channel inhibitors which may have safety and efficacy advantages over non-selective inhibitors. 

4 

 
While the pharmaceutical industry has shown significant interest in channelopathies, a general inability to target ion channels 

selectively with a pharmaceutical agent has been a limitation to the development of effective therapeutics. We believe we have 
developed a core competence in developing highly-selective small-molecule ion channel inhibitors, and we believe we can use this 
know-how to develop a pipeline of novel ion channel inhibitors for diseases in areas of high unmet medical need. 

For example, we discovered that deficiency of the voltage-gated sodium channel Nav1.7 is present in the rare human disease 
called congenital indifference to pain, or CIP. Individuals with CIP are unable to feel pain. This relationship indicated that Nav1.7 
may be a key mechanism for the development of novel analgesics. We are pursuing this mechanism in separate partnerships with Teva 
and with Genentech. 

Similarly, with our collaborators from McGill University, we identified the genetic link between rare human epilepsies and 
mutations in the Nav1.1 sodium channel. These genetic epilepsy discoveries helped to define our therapeutic selective ion channel 
strategy for rare childhood epilepsies. We believe that our extensive ion channel knowledge and Extreme Genetics discovery platform 
provide the opportunity to validate additional ion channel targets for both prevalent and orphan indications.

Our Pipeline 

Our pipeline is summarized in the following figure, which shows our own proprietary product candidates and our partnered 

programs: 

Our Proprietary Product Candidates  

XEN801 for the Treatment of Acne 

XEN801 is a selective, small molecule inhibitor of SCD1 being developed for the treatment of moderate to severe acne. SCD1 is 

an enzyme involved in lipid synthesis that is expressed in sebaceous glands in the skin. Mice deficient in SCD1 have a marked 
phenotype of sebaceous gland atrophy suggesting that inhibition of SCD1 activity in the skin may provide a novel treatment option for 
acne and other disorders of enlarged or overactive sebaceous glands. Published literature studying animals deficient in skin SCD1 
have shown that these animals have lower levels of certain lipids produced by sebaceous glands, increased levels of retinoic acid, and 
increased levels of retinoic acid induced proteins including greatly elevated expression of Lipocalin-2, or LCN2, a gene which 
transcribes neutrophil gelatinase-associated lipocalin, or NGAL. NGAL has been shown to mediate sebaceous gland cell death and 
may also have antibacterial properties. LCN2 is also highly upregulated and NGAL levels increased in a human sebaceous gland cell 
line treated with a SCD1 inhibitor. Published reports on isotretinoin, an approved acne treatment, also support the theory that 
isotretinoin’s therapeutic effects are achieved in part through increasing levels of NGAL. 

We have discovered and developed novel small-molecule SCD1 inhibitors to which we have sole rights. In multiple preclinical 

models, we have shown that our SCD1 inhibitors can reduce the size and number of sebaceous glands. XEN801 has demonstrated 
good properties for topical administration including formulation in a light gel and adequate skin penetration in multiple animal 
species. 

In preclinical mouse models, XEN801 was applied topically and showed reduction in the size of sebaceous glands in the 
underlying skin in a time and dose dependent manner. At the vehicle treated sites, numerous normally sized lipid loaded sebaceous 
glands are visible whereas only very small sebaceous glands with hardly any visible lipids are present at the XEN801 treated sites. 
These reductions are visible after two days of twice-daily treatment and reached statistical significance after seven days (data 
presented in figure below), reverting to normal levels once the treatment is stopped. Skin areas distant from the XEN801 treated sites 
exhibit no changes in sebaceous glands, which is consistent with the observed low plasma concentrations of XEN801 and the high 
local concentrations found in the skin at the treated sites. 

6 

 
 
 
Because there are no preclinical models of acne, human sebocytes, which are the cells that make up the sebaceous glands and 

secrete sebum, are a useful research tool for a variety of applications including acne. In a human sebocyte cell line exposed to 
XEN801, we have observed an increase in NGAL expression and apoptosis with a greater than two-fold increase in the apoptosis 
marker caspase-3 cleavage protein (data presented in figure below). 

We believe preclinical data generated with XEN801 support the clinical development of XEN801 for acne and potentially other 

dermatological disorders. 

Clinical Development of XEN801 

In September 2015, we initiated a Phase 1 clinical trial of XEN801, which was completed by the end of 2015. In the XEN801 

Phase 1 clinical trial, 48 healthy volunteers were dosed for either a 14-day or 21-day treatment period. A number of different dose 
volumes of the 1% XEN801 drug product were evaluated in the Phase 1 clinical trial with dosing on the back and face of healthy 
volunteers to determine the maximum tolerated dose. As expected, the most common side effects were localized, generally mild skin 
reactions. No serious adverse events were observed. Maximal plasma concentrations of XEN801 were low, whereas skin biopsies 
from the back of subjects showed a concentration of approximately two orders of magnitude higher than the IC50. It is expected that 
even better penetration will be shown in the facial skin. A Phase 2 dose was selected based on favorable tolerability and skin drug 
concentrations.

In February 2016, we initiated a Phase 2 clinical trial in patients with moderate to severe acne. Enrollment of 165 subjects is 
now complete in the XEN801 Phase 2 clinical trial, which is a randomized, double-blind, multi-center, vehicle-controlled, parallel-
group study designed to evaluate the efficacy, safety, tolerability and systemic exposure of XEN801 for the treatment of moderate to 
severe facial acne. Patients apply a gel formulation of XEN801 (or vehicle placebo) topically to their face once daily in the evening 
for 12 weeks with a 4-week follow up. The primary efficacy endpoint is the percent change in total (inflammatory and non-
inflammatory) lesion count from baseline to week 12. Secondary endpoints include separate efficacy assessments of inflammatory 
lesion counts, non-inflammatory lesion counts, and Investigator's Global Assessment, or IGA, measures. Topline results from the 
XEN801 Phase 2 clinical trial are expected in the latter part of the first quarter of 2017. 

About Acne 

Acne is a multifactorial disease of the pilosebaceous unit, which are skin structures consisting of a hair follicle and its associated 

sebaceous gland. Increased levels of androgens, such as testosterone, which occurs during puberty cause an enlargement of the 
sebaceous gland that increases the amount of sebum production, a naturally occurring oil. Acne develops as a result of blockages in 
the hair follicles due to the sebaceous glands becoming clogged with excess sebum and dead skin cells. Under these conditions, the 
bacteria proprionibacterium acnes can multiply and cause the noticeable inflammatory lesions. We believe that topically applied 
SCD1 inhibitors will treat acne at its root cause by reducing the underlying sebaceous gland enlargement and reducing sebum 
production. With its association with the onset of puberty, acne prevalence peaks in late adolescence and is estimated to affect 40 to 
50 million people in the U.S, of which there are approximately 11 million and 1.2 million individuals with moderate and severe acne, 
respectively. 

Milder forms of acne are normally treated with over the counter products such as those containing benzoyl peroxide whereas 

moderate and severe forms of acne are often treated with the prescription drug isotretinoin. Isotretinoin is effective with the majority 
of patients reporting an improvement and approximately 50% of patients reporting remission of their acne. Scientific studies have 
shown that isotretinoin can cause apoptosis, a form of cell death, in sebaceous glands thereby reducing sebum production. Isotretinoin 
treatment has been associated with relatively common side effects including thin and dry skin, hair loss, severe acne flares, blood lipid 
and liver enzyme elevations. However, the most significant adverse event of isotretinoin is birth defects if taken by women during 
pregnancy or even a short time before conception due to its teratogenic potential. In 2005, the U.S. Food and Drug Administration, or 
FDA, approved a risk management plan for isotretinoin called iPLEDGE. Under this program, general practitioners are prohibited to 
prescribe isotretinoin and patients are referred to dermatologists registered and activated in the iPLEDGE program. In addition, 
patients are also required to register and qualify for the iPLEDGE program. Isotretinoin can only be dispensed for a 30-day supply (no 
refills) by a registered pharmacy. We believe that a safer alternative drug (without an onerous risk mitigation plan) that potently 
reduces sebum production may be a significant treatment option for moderate to severe acne. 

XEN901, A Selective Small-Molecule Nav1.6 Inhibitor for the Treatment of Epilepsy Disorders 

We are developing XEN901, which is a selective inhibitor of the voltage-gated sodium channel Nav1.6, for the treatment of rare 

infantile epileptic encephalopathies and other forms of epilepsy. We have developed considerable expertise in voltage-gated sodium 
channel biology and have accumulated significant experience in the development of selective sodium channel inhibitors. We expect to 
file an IND, or IND equivalent, application for XEN901 in the fourth quarter of 2017. 

With our collaborators from McGill University, we identified the genetic link between rare human epilepsy and mutations in the 

Nav1.1 gene. Nav1.1 plays a critical role in the normal functioning of inhibitory pathways in the brain. The lack of fully functioning 
Nav1.1 and inhibitory pathways allows the brain excitatory pathways to be unopposed resulting in the severe seizures of Dravet 
Syndrome, which is one example of a rare infantile epileptic encephalopathy. The brain excitatory pathways are preferentially 
mediated by the voltage-gated sodium channel Nav1.6. Published data have shown that seizures and premature death observed in a 
Dravet Syndrome mouse model can be corrected when these animals are bred with a Nav1.6 knockout mouse. Therefore, if we are 
able to selectively inhibit Nav1.6 with a small-molecule compound, we expect to taper this neuronal excitation and thereby treat rare 
forms of severe childhood epilepsy.  

There are other intractable, rare childhood seizures that may benefit from a selective inhibitor of Nav1.6, including rare and 

intractable childhood epilepsies, such as SCN8A (or Nav1.6 gain-of function) epilepsy. These patients represent potential candidates 
for a selective Nav1.6 inhibitor since such a compound would directly target the disease. Many distinct SCN8A mutations have been 
linked to seizures in humans and we have generated preclinical data showing that a number of these patient-identified Nav1.6 gain-of-
function mutant channels are sensitive to our selective Nav1.6 inhibitors. In addition, using our Nav1.6 inhibitors, we have shown 
compelling dose dependent efficacy in a transgenic SCN8A gain-of-function mouse model of seizures. 

8 

 
Non-selective sodium channel blockers have long been used to treat more common epilepsies like adult partial onset epilepsy. If 

the block of Nav1.6 is important for the efficacy in treating these disorders, a selective Nav1.6 inhibitor might provide improved 
efficacy with a reduced burden of off-target adverse events. We have studied the ability of our selective Nav1.6 inhibitor compounds 
to protect wild type mice from seizures in the maximal electroshock seizure, or MES, animal model. The MES assay has been well 
validated against known anti-epileptic drugs, or AEDs, and is believed to provide a reasonable assessment of the potential activity in 
adult partial epilepsies. MES induced seizures in wild type mice are reduced by XEN901 in a dose dependent manner, similar to that 
seen in SCN8A gain-of-function mice. This suggests that the efficacy of Nav1.6 selective inhibitors may not be limited to patients 
with SCN8A gain-of-function mutations and could also include more prevalent adult epilepsy disorders.  

New Pipeline Opportunities 

Given our expertise in ion channel drug discovery, our efforts are concentrated on the identification of ion channel targets where 

we believe novel selective inhibitors might represent significant therapeutic advances, with a particular focus on orphan indications. 
We intend to expand our pipeline either from our internal research efforts or through acquiring or in-licensing other product 
candidates or technologies. 

Our Partnered Programs 

TV-45070: A Small Molecule for the Treatment of Pain being Developed by Teva 

TV-45070 (formerly XEN402) is a small-molecule inhibitor of the sodium channel Nav1.7 and other sodium channels, 
including those that are expressed in the pain-sensing peripheral nervous system. TV-45070 has potential application in neuropathic 
pain mediated by damage, dysfunction, or injury of nerves. We selected Nav1.7 as a drug target for pain after we discovered that the 
Nav1.7 protein is deficient in the rare human disease, CIP, where humans suffering from CIP are unable to feel pain.  

In December 2012, we entered into a collaborative development and license agreement with Teva through its subsidiary Ivax, 

pursuant to which we granted Teva an exclusive worldwide license to develop and commercialize TV-45070. For a more detailed 
description of the terms of our agreement with Teva, see “—Strategic Alliances” below. Using a topical ointment formulation of TV-
45070, Teva is currently conducting a randomized, double-blind, placebo-controlled Phase 2b clinical trial in patients with PHN with 
results expected in mid-2017. Pursuant to the terms of our agreement with Teva, Teva is obligated to complete one additional Phase 2 
or later stage clinical trial.  

Discovery of TV-45070 and Mechanism of Action 

Using our Extreme Genetics discovery platform, we discovered Nav1.7 by studying families with the rare disorder CIP. Patients 

with CIP are unable to feel pain for painful events including fractures, childbirth, osteomyelitis, severe burns, ulcers, wounds and 
tooth abscesses. Based on this severe phenotype of absence of pain in humans with CIP, we predicted that the single-gene defect 
causing CIP could define an important novel human drug target for treating pain. We showed that defects in the CIP gene result in 
deficiency of the sodium channel Nav1.7. 

Nav1.7 is highly expressed in peripheral nerves and transmits pain signals. We believe that inhibition of Nav1.7 may reduce 

these pain signals. TV-45070 was designed to be a non-selective small-molecule inhibitor of Nav1.7 such that it also can inhibit 
additional sodium channels, including those that we believe play a role in pain signaling. We believe this mixed sodium channel 
inhibition may enhance the potential efficacy of TV-45070 in chronic pain. TV-45070 is currently being developed as a topical 
product as its chemical properties are favorable for topical administration, including high local skin and underlying tissue 
concentrations with low plasma levels. With these properties, we believe we can target the site of generation of peripherally-based 
pain without unnecessarily exposing other tissues to significant levels of this compound. This is especially true for the central nervous 
system where we might expect to observe side-effects when multiple sodium channels are inhibited, such as sleepiness, nausea, and 
dizziness. We have demonstrated efficacy with this compound in multiple animal models for pain including both nociceptive and 
neuropathic pain models. The broad sodium channel inhibition of TV-45070 is in contrast to our selective inhibitors licensed to 
Genentech, which are selective for Nav1.7 and are being developed as oral formulations. 

Clinical Development of TV-45070 

We are collaborating with Teva on the development of topical TV-45070. Teva is currently conducting a Phase 2b clinical trial 
in patients with PHN. Previously, we observed promising evidence of activity for TV-45070 in four Phase 2 proof-of-concept clinical 
trials, including two trials in the orphan disease erythromelalgia, or EM, one trial in PHN and one trial in dental pain, a form of 
nociceptive pain.  

9 

 
The previously completed PHN Phase 2 proof-of-concept trial of topical TV-45070 was studied in 70 patients. Patients enrolled 

into the study had refractory PHN and their average disease duration was 76.6 months. This study was a double-blind, placebo-
controlled, crossover trial where topical (8% ointment) TV-45070 was administered twice daily with each patient receiving either TV-
45070 or placebo for three weeks, then after a washout period, the subjects received the alternative treatment. In this study, topical 
TV-45070 was well-tolerated with no drug-related SAEs. The results showed there was a reduction in the primary efficacy endpoint 
(change from baseline in the mean daily pain score) for both TV-45070 and placebo, but the difference between treatments was not 
statistically significant. However, in analysis of certain secondary endpoints, there was a significantly increased proportion of TV-
45070-treated patients who reported 30% or greater (p=0.049) and 50% or greater (p=0.0078) reduction in their pain compared to 
placebo and a retrospective exploratory analysis not described in the study protocol showed that a significant increased proportion of 
TV-45070-treated patients reported 30% or greater improvement in sleep (p=0.034) compared to placebo. 

In addition to the promising efficacy findings from our PHN proof-of-concept trial, there are a number of key factors supporting 

the rationale to develop TV-45070 in PHN including: 

(cid:120)  We observed improved responder rates for carriers of the R1150W variant in our PHN Phase 2 proof-of-concept trial. The 

R1150W variant is a genetic pain biomarker believed to be related to pain susceptibility. 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

Topical TV-45070 has exhibited an ability to penetrate the skin of PHN patients and reside locally, in both the skin and 
underlying tissue, at relatively high concentrations. 

Application of TV-45070 to the human torso in Phase 1 and Phase 2 clinical trials to date resulted in low systemic 
exposure of TV-45070, which may reduce systemic adverse events. 

Central nervous system, or CNS, side effects were not observed in the topical PHN trial due to low plasma levels, which 
we believe is a benefit given evidence that PHN patients have shown poor compliance with products that trigger common 
CNS side effects. 

Lidocaine, a weak sodium channel blocker, provides relief of PHN pain and is approved and widely used for this 
indication. 

TV-45070 Phase 2b Clinical Trial in PHN 

Teva is currently conducting a Phase 2b trial in patients with PHN. The Phase 2b trial, which was initiated in April 2015, is a 

randomized, double-blind, placebo controlled, multi-site study to evaluate the efficacy and safety of TV-45070 in patients with PHN. 
The study includes three treatment groups that receive doses of 4% or 8% of TV-45070 or placebo, dosed twice daily. Approximately 
330 patients will be enrolled in the study, with the goal of having approximately 264 completers. Patients will be stratified into 
treatment groups based on their R1150W status. The primary endpoint of this study is the change from baseline to week 4 in the 
numeric rating scale, or NRS, scores. Secondary endpoints include additional pain measurement scores at specified daily time points, 
the percentage of patients with greater than 30% and greater than 50% improvement in pain scores, quality of life measurements and 
adverse events measurements. Topline results are expected in mid-2017. 

About Post-Herpetic Neuralgia (PHN) 

PHN is a painful complication of Herpes zoster infection, occurring particularly in patients above the age of 50. Herpes zoster, 

otherwise known as shingles, generally manifests as a painful skin rash with blisters in a limited area on one side of the body. Pain can 
occur both before and during the rash, and can also persist after the infection has resolved. PHN is defined as pain that persists for 120 
days or longer after the onset of rash. It is estimated that the annual incidence of Herpes zoster is between 230 and 630 cases per 
100,000 people, with PHN occurring in approximately 20% of cases, resulting in approximately 200,000 PHN patients in the U.S. 

Like other forms of neuropathic pain, there is a need for improved treatments for PHN. The current leading drugs used to treat 

PHN suffer from low efficacy for many patients and common dose limiting side effects. It has been reported that 30% to 50% of PHN 
patients achieve a 30% to 50% improvement in their pain with these agents. Currently prescribed treatments include Lyrica 
(pregabalin) and generic forms of gabapentin, both of which target the same mechanism. Common side effects for these drugs include 
sleepiness, dizziness, blurred vision, edema and weight gain. 

Selective Inhibitors of Nav1.7 for the Treatment of Pain being Developed by Genentech 

In December 2011, we entered into a collaborative research and license agreement with Genentech and its affiliate, F. Hoffman-

La Roche Ltd, or Roche, to discover and develop selective oral inhibitors of Nav1.7 for the treatment of pain. For a more detailed 
description of the terms of this agreement with Genentech, see “—Strategic Alliances” below.  

10 

 
Based on our discovery of Nav1.7 deficiency underlying CIP, we believe that Nav1.7 is a highly-validated target for the 
treatment of pain. In contrast to our Teva partnership that is focused on developing a topical drug that targets a number of different 
sodium channels, including Nav1.7, our Genentech collaboration is focused on discovering and developing an oral drug that 
selectively targets Nav1.7. The collaboration with Genentech has advanced two oral selective Nav1.7 inhibitors, GDC-0276 and GDC-
0310, into development. 

To study the effects of targeting Nav1.7 for the treatment of pain, we developed an animal model of inherited EM, or IEM, by 
expressing human Nav1.7 carrying a known IEM mutation in mice. These mice demonstrate a greater sensitivity to pain. Using this 
IEM model, as shown in the figure below, with a single dose of GDC-0276, these mice had fewer pain events demonstrating the 
ability of GDC-0276 to inhibit Nav1.7 in vivo. 

Clinical Development 

Genentech has completed two Phase 1 clinical trials for GDC-0276 and GDC-0310. Genentech has indicated that it intends to 

focus its ongoing development efforts on GDC-0310. Pending a full assessment of the Phase 1 clinical results and ongoing in vivo 
studies, Genentech anticipates initiating a Phase 2 clinical trial in 2017 for the potential treatment of pain.  

Chronic pain conditions, such as severe cancer pain and neuropathic pain, are generally recognized as unmet medical needs 

providing potential commercial opportunities for a new oral pain drug. Currently available pain drugs often have either a lack of 
meaningful pain relief or dose limiting side effects for many patients. An orally administered selective Nav1.7 inhibitor could present 
a novel mechanism for the treatment of moderate to severe pain as a single agent or in combination with existing analgesics that work 
through different mechanisms. We believe that the selective inhibition of Nav1.7 may lower the potential for dose-limiting central 
nervous system side-effects and allow for an improved side-effect profile for oral administration of such an inhibitor, which could 
potentially allow for the treatment of pain that has a central or deep tissue component, including cancer pain and neuropathic pain. 

Other Collaborative Work with Genentech 

We formed a second collaboration with Genentech in March 2014 for pain genetics, where we intend to focus on rare 

phenotypes where individuals have an inability to perceive pain or where individuals have non-precipitated spontaneous severe pain. 
For a more detailed description of the terms of this second agreement with Genentech, see “—Strategic Alliances” below. We believe 
these phenotypes may unlock new key molecular regulators of pain signaling in humans, which we will seek to validate as targets for 
new pain drugs. For example, we are analyzing CIP families that are not explained by Nav1.7 deficiency as well as families with 
conditions associated with severe pain phenotypes such as paroxysmal extreme pain disorder, or PEPD, inherited EM and cluster 
headache.

Glybera (alipogene tiparvovec): A Gene Therapy for the Orphan Disease LPLD 

Glybera is a gene therapy product approved in the EU in October 2012 for the treatment of a subset of patients with the orphan 

lipid disorder lipoprotein lipase deficiency, or LPLD. Specifically, it is intended to treat LPLD in patients with severe or multiple 
pancreatitis attacks, despite dietary fat restrictions. LPLD is a severe metabolic disease of inadequate lipid metabolism, resulting in 
pancreatitis and in some cases, death. In collaboration with the University of British Columbia, or UBC, we demonstrated that humans 
with a variant of the lipoprotein lipase, or LPL, gene called LPLS447X resulted in increased LPL enzyme activity leading to reduced 
triglyceride levels. Under our sublicense and research agreement with uniQure, we collaborated with uniQure and UBC on preclinical 
activities, and thereafter uniQure developed a LPL gene therapy product, Glybera, which contains the LPLS447X variant. We believe 
that the introduction of the therapeutic LPLS447X gene through administration of Glybera provides a clinical benefit for LPLD patients. 

Glybera is the first product whose active ingredient was derived from our platform to receive commercial approval and was the 

first gene therapy product to be approved in the EU. The goal of Glybera therapy is to treat LPLD in order to achieve sustained 
improvement of clearance of triglyceride-rich lipid particles known as chylomicrons, and to significantly reduce the risk of 
pancreatitis attacks in patients suffering from multiple recurrent pancreatitis and abdominal pain events.  

About LPLD 

Familial LPLD is a rare autosomal-recessive disorder of lipoprotein metabolism. LPLD is characterized by severe 

hypertriglyceridemia caused by the absence of LPL activity, and, as a consequence, certain triglyceride-rich lipoproteins accumulate 
in the plasma. The population frequency of LPLD in the U.S. has been reported to be approximately one in a million individuals by 
the National Library of Medicine. 

LPLD typically manifests early in childhood, with repeated episodes of abdominal pain and acute pancreatitis that can be life-
threatening. There is currently no approved gene therapy for LPLD in the U.S. The current management of LPLD consists of strict 
adherence to an extremely low-fat diet, but compliance with such a diet is challenging. Lipid-lowering drugs are generally not 
effective for treating LPLD. We believe effective therapeutic strategies are therefore needed for this condition. 

About LPLS447X 

Together with our collaborators at UBC and using our Extreme Genetics discovery platform, we demonstrated that the LPLS447X 

variant resulted in reduced triglyceride levels in humans, as this single-gene defect results in elevated LPL enzyme activity, and we 
further demonstrated that LPLS447X in an adenovirus gene therapy could treat hypertriglyceridemia in animal models of LPLD. 

Clinical Development of Glybera 

In a scientific publication, a single dose of Glybera was well-tolerated with no material safety concerns and was demonstrated to 

reduce the incidence of acute pancreatitis and abdominal pain events over the two-year study period. 

Commercialization of Glybera 

In 2012, Glybera was approved in the EU for the orphan disorder LPLD to treat patients with severe or multiple pancreatitis 
attacks. In July 2013, uniQure announced that it had entered into a partnership with Chiesi for the commercialization of Glybera in the 
EU and more than a dozen other countries including Brazil, China, Mexico and Russia. Glybera has received both fast-track and 
orphan drug designations for the treatment of LPLD in both the EU and the U.S. The first patient treated with Glybera as a 
commercially-available gene therapy in the EU was announced by uniQure in November 2015. Although commercial sales of Glybera 
have now commenced, we do not expect to receive significant revenue from these sales. uniQure also disclosed in November 2015 
that it will not pursue U.S. regulatory approval of Glybera in order to maintain its focus on three core therapeutic areas. uniQure has 
announced that it will not provide additional guidance regarding commercialization progress for Glybera. For a more detailed 
description of the terms of our agreement with uniQure for Glybera, see “—Strategic Alliances” below. 

Selective Small-Molecule Inhibitors of Targets for the Treatment of Cardiovascular Disease 

We entered into a collaborative research and option agreement with Merck in June 2009 to discover novel targets and 
compounds for the treatment of cardiovascular disease using our Extreme Genetics discovery platform. For a more detailed 
description of the terms of our agreement with Merck, see “—Strategic Alliances” below. In 2012, Merck exercised its option to 
obtain an exclusive license to a target for cardiovascular disease and compound inhibitors that were discovered during the research 
collaboration. The target, when inhibited, is predicted to provide a beneficial lipid profile with the goal of protecting from 
cardiovascular disease.

Strategic Alliances  

Agreement with Teva for TV-45070 

In December 2012, we entered into a collaborative development and license agreement with Teva, through its subsidiary, Ivax, 

pursuant to which we granted Teva an exclusive worldwide license to develop and commercialize certain products, including TV-
45070.Under the terms of the agreement, Teva paid us an upfront fee of $41.0 million. We are collaborating with Teva to further 
develop TV-45070, and Teva is funding all development costs with respect to the licensed products. In addition, we are eligible to 
receive potential milestone payments totaling up to $335.0 million, comprised of a $20.0 million clinical milestone payment, up to 
$285.0 million in regulatory milestone payments, and a $30.0 million sales-based milestone payment. If TV-45070 is approved, we 
are also eligible to receive royalties in the low teens to the low twenties on net sales of the licensed products for the timeframe ending 
upon the latest of (a) expiration of the last valid claim of a licensed patent covering the product, (b) the date on which such product 
loses market exclusivity and (c) the 10th anniversary of first commercial sale, in each case on a country-by-country basis. 

We have an option to a 20% to 30% co-promotion interest for products incorporating TV-45070 in the U.S. Our exercise of this 
option is subject to meeting objective financial conditions, staffing requirements and compliance standards to be determined in Teva’s 
reasonable discretion in accordance with standard industry practice. Our co-promotion option is exercisable upon the filing of the first 
new drug application, or NDA, for a TV-45070 product with the FDA and we will be obligated to pay an opt-in fee to Teva, which is 
calculated by multiplying our co-promotion interest (as a percentage) by the amount of certain milestones paid or payable by Teva, to 
which is added certain past and future development costs incurred by Teva with respect to the product for the U.S. Our co-promotion 
interest is in the 20% to 30% range, and equals our percentage share of detailing activities and co-promotion expenses. Such opt-in fee 
is payable as a reduction to the milestone payments or our share of operating profits that Teva would otherwise owe to us or a 
combination of the two. If we exercise this option, upon paying an opt-in fee to Teva, we will be eligible to receive, in lieu of royalties 
with respect to such product sales in the U.S., a percentage share (equal to our co-promotion interest) of operating profits from such 
product sales in the U.S. 

Our agreement with Teva expires on the date of the expiration of all payment obligations to us under the agreement. Teva may 
terminate the agreement with 60 days advanced written notice to us after at least three Phase 2 (or later stage) clinical trials have been 
completed or in the event that safety or efficacy issues arise in the development of the licensed products. Either party may terminate 
the agreement in the event of the other party’s material breach which remains uncured for 90 business days. In certain termination 
circumstances, we would receive licenses to Teva intellectual property relating to TV-45070 clinical development and regulatory 
filings. If patents within such Teva intellectual property cover the TV-45070 product, then Teva is eligible to receive royalties from us 
based on a percentage of net product sales, within the mid single-digit range. 

Agreements with Genentech for Selective Inhibitors of Nav1.7 and Pain Genetics 

In December 2011, we entered into a collaborative research and license agreement with Genentech and its affiliate, Roche, to 

discover and develop small and large molecules that selectively inhibit the Nav1.7 sodium channel and companion diagnostics for the 
potential treatment of pain. Pursuant to this agreement, we granted Genentech a worldwide exclusive license to develop and 
commercialize compounds directed to Nav1.7 and products incorporating such compounds for all uses. We also granted Genentech a 
worldwide non-exclusive license to diagnostic products for the purpose of developing or commercializing such compounds. 

Under the terms of the agreement, Genentech paid us an upfront fee of $10.0 million, a $5.0 million milestone payment for the 
selection of GDC-0276 for development and an $8.0 million milestone payment upon the approval by Health Canada of the clinical 
trial application, or CTA, for GDC-0276. Genentech provided funding to us for certain of our full-time equivalents, or FTEs, 
performing the research collaboration plan. In addition, we are eligible to receive pre-commercial and commercial milestone payments 
with respect to the licensed products totaling up to an additional $613.0 million, comprised of up to $45.5 million in preclinical and 
clinical milestone payments, up to $387.5 million in regulatory milestone payments, and up to $180.0 million in sales-based milestone 
payments for multiple products and indications. In addition, we are eligible to receive royalties based on net sales of the licensed 
products, which range from a mid single-digit percentage to ten percent for small-molecule inhibitors for the timeframe that such 
products are covered by the licensed patents and a low single-digit percentage thereafter until the date that is ten years after first 
commercial sale on a country-by-country basis, plus a low single-digit percentage for large molecule inhibitors of Nav1.7 for a period 
of ten years from first commercial sale on a country-by-country basis.

Our agreement with Genentech expires on the date of the expiration of all payment obligations to us under the agreement. 

Genentech may terminate the agreement with three months advance notice anytime on or after the third anniversary of the effective 
date of the agreement, and each party may terminate the agreement in the event of a material breach by the other party that remains 
uncured after 90 days. In the event that Genentech terminates the agreement due to our breach, Genentech retains its licenses and its 
payment obligations to us are reduced. In the event that we terminate the agreement due to Genentech’s breach, the rights and licenses 
granted to Genentech revert back to us, subject to certain rights to make and use certain large-molecule product candidates that are 
retained by Genentech, and Genentech is obligated to assign certain regulatory approvals and grant certain licenses to us to enable us 
to develop and commercialize certain terminated products outside of the collaboration. 

In May 2015, we amended the collaborative research and license agreement to leverage the work performed in our ongoing 

Nav1.7 pain collaboration with Genentech for use in our research and development program directed towards modulators of Nav1.6 
for use in the field of treating epilepsy. Pursuant to the amendment, we obtained a worldwide, non-exclusive, revocable license under 
intellectual property previously licensed by us to Genentech and intellectual property developed under the Nav1.7 collaboration that is 
necessary or useful to make and use certain Nav1.6 modulators for use in the field, excluding commercialization. We obtained a right 
of first negotiation for a certain period of time to obtain a worldwide, exclusive license under the intellectual property previously 
licensed by us to commercialize certain Nav1.6 modulators to treat any disease in the field. We also granted Genentech a right of first 
negotiation to enter into a drug research and development collaboration with us for our Nav1.6 program. Genentech can terminate the 
license upon 90 days’ notice after the third anniversary of the amendment or at any time upon our uncured material breach. 

Pursuant to the amendment, we granted Genentech a worldwide exclusive license under intellectual property developed under 

our Nav1.6 program. The license permits Genentech to develop and commercialize compounds identified or first made in our Nav1.6 
program for all uses outside the field of epilepsy and to develop and commercialize compounds (other than certain compounds 
identified or first made in our Nav1.6 program) for all uses. If Genentech reaches certain development milestones for and/or sells 
certain compounds identified or first made in our Nav1.6 program that are covered by a patent licensed to Genentech under the 
amendment, products containing such compound would be included in the products subject to the royalty and milestone obligations 
payable to us under the original agreement. The collaborative research and license agreement was amended in December 2015 to 
extend the term of the research program and, in March 2016, the agreement was amended again, pursuant to which we obtained a non-
sublicensable, non-transferable, royalty free, non-exclusive license to make, use and test certain collaboration compounds developed 
under the Nav1.7 collaboration for internal research purposes during the term of the collaboration.  

In March 2014, we entered into an additional agreement with Genentech for pain genetics, where we intend to use our Extreme 

Genetics discovery platform to focus on identifying genetic targets associated with rare phenotypes where individuals have an 
inability to perceive pain or where individuals have non-precipitated spontaneous severe pain. Pursuant to the terms of this agreement, 
any intellectual property arising out of the collaboration will be jointly owned by us and Genentech. We have also granted Genentech 
a time-limited, exclusive right of first negotiation on a target-by-target basis to form joint drug discovery collaborations. Under the 
terms of this agreement, Genentech paid us an upfront payment of $1.5 million, a $0.25 million milestone payment related to the 
identification of a novel pain target in September 2015, and we are eligible for an additional $1.75 million in milestone payments. The 
agreement terminates upon the expiration of Genentech’s time-limited, exclusive right of first negotiation which shall be exercisable 
for two years. Genentech may terminate the agreement with three months advance notice anytime on or after the 12 month anniversary 
of the effective date of the agreement, and each party may terminate the agreement in the event of a material breach by the other party 
that remains uncured for 90 days. In March 2016, the research term for this agreement was extended until March 2017. 

Agreement with uniQure for Glybera 

Effective August 2000, we entered into a sublicense and research agreement with uniQure (formerly Amsterdam Molecular 

Therapeutics) pursuant to which we granted to uniQure an exclusive, worldwide sublicense under certain intellectual property 
controlled by us to develop and commercialize technology and compounds related to the variant of LPL, called LPLS447X. Together 
with collaborators from UBC, we demonstrated that the LPLS447X variant resulted in increased LPL enzyme activity leading to reduced 
triglyceride levels in humans. Under our sublicense and research agreement with uniQure, we collaborated with uniQure and UBC on 
preclinical activities, and thereafter uniQure developed an LPL gene therapy product, Glybera, which contains the LPLS447X variant. 
Glybera was approved in the EU in October 2012 to treat LPLD in patients with severe or multiple pancreatic attacks despite dietary 
fat restrictions. uniQure conducted the clinical trials and is responsible for the commercialization of Glybera. 

14 

 
Under the terms of the agreement, we are eligible to receive mid single-digit royalties on net sales of the licensed products, for 

sales made by uniQure and its affiliates. The royalty rates are reduced to a low single-digit for sales made by uniQure and its affiliates 
in countries where a licensed technology or a licensed product is not covered by a valid patent claim. Such royalties are payable until 
the expiration of the last licensed patent from UBC. With respect to uniQure’s sublicense to Chiesi, we are eligible to receive a 
percentage in the low twenties of all non-royalty compensation relating to the licensed technology or products that uniQure receives 
from Chiesi (for example upfront payments and milestone payments), a percentage in the low twenties of any royalties that uniQure 
receives from Chiesi based on sales of technology or products covered by the licensed patents, plus a mid single-digit percentage of 
certain further royalties that uniQure receives from Chiesi based on sales of our licensed technology or products after the expiration of 
all licensed patents covering the licensed technology or products during the period expiring ten years after the date of the first sale by 
or on behalf of Chiesi. If uniQure grants a sublicense to a third party other than to Chiesi, then we are eligible to receive a percentage 
in the low twenties of all non-royalty compensation relating to the licensed technology or products that uniQure receives from such 
sublicensee (for example upfront payments and milestone payments), plus a percentage in the low twenties of any royalties that 
uniQure receives from such sublicensee based on sales of technology or products covered by the licensed patents. Although 
commercial sales of Glybera commenced in the fourth quarter of 2015, we do not expect to receive significant revenue from these 
sales. Furthermore, royalties we are eligible to receive pursuant to our agreement with uniQure, including royalties related to sales 
made by Chiesi, are subject to customary royalty stacking deductions in the event that uniQure, or any of its sublicensees, have to 
license other technologies in order to commercialize Glybera. 

We are eligible to receive certain additional milestone payments of less than CAD$1.0 million for Glybera and for each 
subsequent product, if any, developed pursuant to the agreement with uniQure. We, in turn, have certain payment obligations to our 
licensor, UBC, based on amounts received from uniQure or otherwise based on the exploitation of the licensed intellectual property. 

Our sublicense agreement with uniQure expires on the date of the expiration of the UBC license agreement. Either party may 

terminate the agreement in the event of the other party’s default under the agreement that remains uncured for 20 days after receipt of 
notice from the non-breaching party. 

Agreement with UBC 

Effective August 2000, we entered into a license agreement with UBC pursuant to which UBC granted to us an exclusive, 
worldwide license under UBC’s interest in certain intellectual property controlled by UBC to develop and commercialize technology 
and compounds in the field of gene therapy, including products that related to the variant of LPL, called LPLS447X. 

Under the terms of the agreement, UBC is eligible to receive certain pre-commercial milestone payments. UBC is also eligible 

to receive a mid single-digit percentage of certain compensation that we receive based on sublicenses granted by us to a third party 
relating to the licensed technology or products, including in connection with our sublicensing agreement with uniQure for LPLS447X. 

Through December 31, 2016, we have paid to UBC upfront fees, milestone payments, and royalties totaling CAD$275,000 and 

are obligated to pay a certain additional milestone payment of approximately CAD$200,000 for Glybera and further milestone 
payments of CAD$322,500 for each subsequent product, if any, developed pursuant to our sublicensing agreement with uniQure. 

Our license agreement with UBC expires on the date of the expiration of the last patent granted under such license. In the event 

that our sublicense with uniQure is terminated, we may terminate the agreement with 30 days advance notice to UBC. Either party 
may terminate the agreement in the event of the other party’s default under the agreement that remains uncured for 30 days after 
receipt of notice from the non-breaching party, and UBC may terminate without such cure period in the event of certain types of 
breach by us. 

Agreement with Merck for Cardiovascular Disease 

In June 2009, we entered into an exclusive collaborative research and option agreement with Merck, pursuant to which the 

parties conducted a research program to discover and develop novel small-molecule candidates for the potential treatment of 
cardiovascular disease. Merck provided payments to us for our FTEs who performed our activities pursuant to the research program 
conducted under the Merck agreement. The Merck collaborative research program ended in December 2012. 

15 

 
Under the terms of the agreement, Merck had the option to obtain an exclusive license under certain intellectual property 
controlled by us to develop and commercialize compounds and products directed to targets in the research program, which has now 
expired. In June 2012, Merck exercised its option and paid us $2.0 million to obtain such a worldwide exclusive license to develop 
and commercialize compound inhibitors of a target that was identified using our Extreme Genetics discovery platform. Through 
December 31, 2016, we have received milestone payments and an option fee totaling $9.0 million, and we are eligible for further 
research, development and regulatory milestone payments of up to $64.0 million, comprised of $21.0 million in preclinical and 
clinical milestone payments and up to $43.0 million in regulatory milestone payments for products directed to the licensed target, as 
well as royalties from the mid to high single-digit range in countries where such products are covered by a valid composition or 
method of use claim of a Xenon or Merck patent or, if not covered by such claims, royalties in the mid single-digit range for ten years 
after first commercial sale of such products. 

We have an option to co-fund the Phase 1 and first Phase 2 clinical trials of product candidates licensed by Merck by paying 

Merck 50% of such development costs. Such co-funding option is available at the IND-filing stage for the applicable product 
candidate. If we exercise our co-funding option then the maximum eligible milestone amounts due to us increase to $86.5 million and 
the royalties increase to the high single-digit to the sub-teen double-digit range. 

Our agreement with Merck expires on the date of the expiration of all royalty payment obligations to us under the agreement. 
Merck has the right to terminate the agreement upon providing certain notices to us. Each party may terminate the agreement in the 
event of a material breach by the other party that remains uncured for 90 days after notice of such breach. In the event that Merck 
terminates the agreement due to our breach, the licenses granted to Merck survive and becomes fully paid up. In the event that we 
terminate the agreement due to Merck’s breach, the licenses granted to Merck terminate. 

Intellectual Property 

As part of our business strategy, we generally file patent applications disclosing and claiming drug targets and their novel uses, 
novel compositions that modulate such targets, methods of making and using such compositions and various therapeutic formulations 
of such compositions that cover our product candidates. In some cases, we also file claims on screening assays as well as compositions 
and methods for use in diagnosing certain diseases. We generally file applications in the U.S., Canada, the EU and other commercially 
significant foreign jurisdictions. We also rely on trade secrets, internal know-how, technological innovations and agreements with 
third parties to develop, maintain and protect our competitive position. Our ability to be competitive will depend on the success of this 
strategy. 

As of December 31, 2016, we owned, co-owned or licensed 61 issued or allowed U.S. patents and approximately 23 pending 
U.S. patent applications, including provisional and non-provisional filings. We also owned, co-owned or licensed an additional 730 
pending and granted counterpart applications worldwide, including 206 country-specific validations of 13 European patents. 

As of December 31, 2016, we owned 17 issued U.S. patents and five pending U.S. patent applications related to TV-45070, and 

methods of making and using this and certain related compounds. The issued patents are expected to expire between 2026 and 2034 
(absent any extensions of term). In addition, we have 92 foreign issued patents (exclusive of European patent national validations) and 
have filed 137 pending corresponding applications in various foreign jurisdictions relating to TV-45070 and certain related 
compounds. 

As of December 31, 2016, we, together with Genentech, co-owned one allowed U.S. patent application, one pending U.S. patent 

application and 23 pending counterpart patent applications worldwide relating to GDC-0310 and methods of making and using this 
and certain related compounds. Any patents issuing from these applications are expected to expire in 2034 (absent any extensions of 
term). 

We have in-licensed from UBC patents related to Glybera, and methods of making and using Glybera. These include U.S. 
Patent No. 9,290,751, European Patent No. 1,200,117, Japanese Patent No. 5,095,894 and Canadian Patent No. 2,370,081, all of 
which are expected to expire in June 2020 (absent any extensions of term). In addition, U.S. Patent No. 6,814,962 has claims directed 
to the use of various recombinant viruses containing LPL coding sequences to treat various pathologies and is expected to expire in 
November 2020 (absent any extensions of term). 

16 

 
As of December 31, 2016, we owned or co-owned four issued U.S. patents related to XEN801, and methods of making and 

using this and certain related compounds. These issued patents are expected to expire between 2024 and 2025 (absent any extensions 
of term). In addition, we have 30 foreign issued patents (exclusive of European patent national validations) and have six pending 
corresponding applications in various foreign jurisdictions relating to XEN801 and certain related compounds. We have also filed a 
further U.S. provisional application directed to pharmaceutical compositions containing XEN801 and their associated methods of use. 
We intend to convert this U.S. provisional application into corresponding U.S. non-provisional and PCT applications in 2017, any 
patents issuing from which would be expected to expire in 2037 (absent any extensions of term). 

As of December 31, 2016, we have filed four U.S. provisional applications directed to selective inhibitors of Nav1.6 and their 

associated methods of use. We intend to convert these U.S. provisional applications into corresponding U.S. non-provisional and PCT 
applications in 2017, any patents issuing from which would be expected to expire in 2037 (absent any extensions of term). 

We may obtain patents on our novel compositions before we obtain marketing approval for product candidates containing such 
compositions. Because patents are only valid for a limited period, and the life of a particular patent may begin prior to the commercial 
sale of the related product, the commercial value of any patent is limited. However, in certain circumstances, we may be able to seek 
patent term extensions for patents in the U.S. and in a number of European countries, compensating in part for delays in obtaining 
marketing approval, but we cannot be certain we will obtain such extensions. 

Further, the existence of issued patents does not guarantee our right to practice the patented technology or commercialize any 
product candidate covered by such a patent. Third parties may have or obtain rights to other patents that could be used to prevent or 
attempt to prevent us from commercializing our product candidates. If these other parties are successful in obtaining valid and 
enforceable patents, and establishing our infringement of those patents, we could be prevented from commercializing our product 
candidates unless we were able to obtain a license under such patents, which may not be available on commercially reasonable terms 
or at all. 

In the conduct of our business, we may infringe patents or other proprietary rights of third parties. If we do infringe such patents 

or other proprietary rights, we could be prevented from developing or selling products or from using the processes covered by those 
patents, could be required to pay substantial damages or could be required to obtain a license from the third party to allow us to use 
their technology, which may not be available on commercially reasonable terms or at all. If we are not able to obtain a required license 
or develop alternative technologies, we may be unable to develop or commercialize some or all of our products, and our business 
could be adversely affected. 

Much of our scientific capabilities depend upon the knowledge, experience and skills of key scientific and technical personnel. 

To protect our rights to our proprietary know-how and technology, we require all our employees, consultants and advisors to enter into 
confidentiality agreements that require disclosure and assignment to us of ideas, developments, discoveries and inventions made by 
these employees, consultants and advisors in the course of their service to us. 

We may be unable to obtain, maintain and protect the intellectual property rights necessary to conduct our business, and we may 

be subject to claims that we infringe or otherwise violate the intellectual property rights of others, which could materially harm our 
business. Although we believe our patents and patent applications provide us with a competitive advantage, the patent positions of 
biotechnology and pharmaceutical companies can be uncertain and involve complex legal and factual questions. We and our 
collaborators may not be able to develop patentable product candidates or processes or obtain patents from pending patent 
applications. Even if patent claims are allowed, the claims may not issue, or in the event of issuance, may not be sufficient to protect 
the technology owned by or licensed to us or to our collaborators. In certain cases where we have licensed rights to our intellectual 
property to our collaborators, such collaborators have assumed control of the prosecution and maintenance of the intellectual property 
portfolio related to such licensed rights. If our collaborators fail to adequately prosecute or maintain any portion of our licensed 
intellectual property, the competitive advantage and value of our intellectual property portfolio may be reduced. For more information, 
see “Risk Factors—Risks Related to Our Intellectual Property Rights.” 

We own a number of trademarks and intend to develop names for our product candidates and as appropriate seek to secure 

trademark protection for them, including domain name registration, in relevant jurisdictions.

Competition 

The biotechnology and pharmaceutical industries are highly competitive and are characterized by rapidly advancing 

technologies and a strong emphasis on proprietary products. While we believe that our technology, development experience, scientific 
knowledge and drug discovery approach provide us with certain advantages, we face potential competition in target discovery and 
product development from many different approaches and sources, including pharmaceutical and biotechnology companies, academic 
institutions and governmental agencies and public and private research institutions. Any product candidates or products that we or our 
collaborators successfully develop and commercialize will compete with existing products and new products that may become 
available in the future. 

With respect to target discovery activities, competitors and other third parties, including academic and clinical researchers, may 

be able to access rare families and identify targets before we do. 

Many of the companies against which we are competing or against which we may compete in the future have significantly 

greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, 
obtaining regulatory approvals and marketing approved products than we do. Mergers and acquisitions in the pharmaceutical and 
biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller 
or early stage companies may also prove to be significant competitors, particularly through collaboration arrangements with large and 
established companies. 

The key competitive factors affecting the success of all of our product candidates, if approved, are likely to be their efficacy, 

safety, convenience, price, the effectiveness of alternative products, the level of competition and the availability of coverage, and 
adequate reimbursement from government and other third party payers. 

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products or therapies 

that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that 
we may develop. Our competitors also may obtain FDA, European Medicines Agency, or EMA, or other regulatory approval for their 
products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market 
position before we are able to enter the market. In addition, our ability to compete may be affected in many cases by insurers or other 
third party payers seeking to encourage the use of generic products. 

Aside from the product marketplace, our competitors also compete with us in recruiting and retaining qualified scientific and 

management personnel, establishing clinical trial sites, recruiting patients for clinical trials, and by acquiring technologies 
complementary to, or necessary for, our programs. 

Our partnered products and proprietary product candidates that are currently approved or are in clinical development may 

compete with various therapies and drugs, both in the marketplace and currently under development. 

TV-45070 and GDC-0310 Competition 

Drug discovery and development for various pain applications is intensely competitive. There are a large number of approved 
products for neuropathic pain, inflammatory pain and other pain indications. These approved products include capsaicin, celecoxib, 
lidocaine, narcotic analgesics, gabapentin, and pregabalin. We are also aware of development programs at several pharmaceutical and 
biotechnology companies that are developing Nav1.7 inhibitors or other sodium channel inhibitors for the treatment of pain, including 
Amgen Inc., AstraZeneca PLC, Biogen Inc., Dainippon Sumitomo Co., Ltd., Eli Lilly and Company, Merck, NeuroQuest Inc., Vertex 
Pharmaceuticals Inc., Voyager Therapeutics, Inc. and Chromocell Corporation in collaboration with its partner Astellas Pharma Inc. 
Moreover, we are aware of various other product candidates in development that target other mechanisms of action to treat various 
pain indications, including calcium channel inhibitors, nerve growth factor inhibitors, and Nav1.8 inhibitors. 

Glybera (alipogene tiparvovec) Competition 

There are no approved gene therapies currently on the market for LPLD. The current management of LPLD consists of strict 

adherence to an extremely low-fat diet, but compliance with such a diet is challenging. Lipid-lowering drugs are generally not 
effective for treating LPLD. We are not aware of any other drugs or therapies currently in development that treat LPLD by using the 
LPL sequence containing the LPLS447X genetic variant or otherwise. 

18 

 
XEN801 Competition 

If XEN801 were approved for the treatment of acne, we anticipate it would compete with other approved prescription acne 
products including topical retinoids, oral hormonal therapies, topical and oral antimicrobials, and oral isotretinoin. In addition to 
approved prescription therapies, there are a wide range of over-the-counter, or OTC, treatments targeted at treating acne. Additionally, 
there are a number of prescription products that are used “off-label” for the treatment of acne. We are also aware of several products in 
clinical development that could potentially compete with XEN801, including products in development from Allergan PLC, AOBiome 
LLC, Braintree Laboratories Inc., Cassiopea SpA, Dermira Inc., Foamix Pharmaceuticals Ltd., Galderma SA, Mimetica Pty Ltd, 
Novan Therapeutics, Phosphagenics Ltd, Thesan Pharmaceuticals, Inc., Valeant Pharmaceuticals, and XBiotech Inc. 

Government Regulation 

We are developing both small-molecule and large-molecule product candidates. Our small-molecule product candidates are 
regulated as drugs by the FDA. Within the FDA, the Center for Drug Evaluation and Research, or CDER, regulates drugs and the 
Center for Biologics Evaluation and Research, or CBER, regulates biological products. Drugs and biological products are subject to 
regulation under the Federal Food, Drug, and Cosmetic Act, or FD&C Act, and other federal, provincial, state, local and foreign 
statutes and regulations. Biological products are also subject to regulation under the Public Health Service Act, or PHS Act. Both the 
FD&C Act and the PHS Act, as applicable, and their corresponding regulations govern, among other things, the testing, 
manufacturing, safety, efficacy, labeling, packaging, storage, record keeping, distribution, import, export, reporting, advertising and 
other promotional practices involving drugs and biological products. FDA approval must be obtained before clinical testing of drugs 
or biological products is initiated, and each clinical study protocol for such product candidates is reviewed by the FDA prior to 
initiation in the U.S. FDA approval also must be obtained before marketing of drugs and biological products in the U.S. The process 
of obtaining regulatory approvals and the subsequent compliance with appropriate federal, provincial, state, local and foreign statutes 
and regulations require the expenditure of substantial time and financial resources and we may not be able to obtain the required 
regulatory approvals. 

Federal and state agencies, congressional committees and foreign governments have expressed interest in further regulating 
biotechnology. In particular, ethical, social and legal concerns about genetic testing, genetic research and gene therapy could result in 
additional regulations restricting or prohibiting the processes we may use in discovering and developing our products candidates and 
in manufacturing and marketing Glybera and any other gene therapy products we or our collaborators may develop. More restrictive 
regulations or claims that our products are unsafe or pose a hazard could prevent us from commercializing any products. New 
government requirements may be established that could delay or prevent regulatory approval of our product candidates under 
development. It is impossible to predict whether legislative changes will be enacted, regulations, policies or guidance changed, or 
interpretations by agencies or courts changed, or what the impact of such changes, if any, may be. 

U.S. Drug Development Process 

The process required by the FDA before a drug or biological product may be marketed in the U.S. generally involves the 

following: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

completion of nonclinical laboratory tests and animal studies according to good laboratory practices, or GLPs, and 
applicable requirements for the humane use of laboratory animals or other applicable regulations; 

submission to the FDA of an application for an IND, which must become effective before human clinical studies may 
begin; 

performance of adequate and well-controlled human clinical studies according to the FDA’s regulations commonly 
referred to as good clinical practices, or GCPs, and any additional requirements for the protection of human research 
subjects and their health information, to establish the safety and efficacy of the proposed product for its intended use; 

submission to the FDA of an NDA for drug products or a biological license application, or BLA, for biological products 
for marketing approval that includes substantive evidence of safety, purity, and potency from results of nonclinical testing 
and clinical studies; 

satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the product is produced to 
assess compliance with good manufacturing practices, or GMP, to assure that the facilities, methods and controls are 
adequate to preserve the product’s identity, strength, quality and purity; 

potential FDA audit of the nonclinical and clinical study sites that generated the data in support of the NDA or BLA; and 

FDA review and approval of the NDA, or licensure of the BLA. 

19 

 
Before testing any drug or biological product candidate in humans, the product candidate enters the preclinical testing stage. 

Preclinical tests, also referred to as nonclinical studies, include laboratory evaluations of product chemistry, toxicity and formulation, 
as well as animal studies to assess the potential safety and activity of the product candidate. The conduct of the preclinical tests must 
comply with federal regulations and requirements including GLPs. 

The clinical study sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical 
data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. Some preclinical testing 
may continue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the 
FDA places the clinical study on a clinical hold within that 30-day time period. In such a case, the IND sponsor and the FDA must 
resolve any outstanding concerns before the clinical study can begin. The FDA may also impose clinical holds on a product candidate 
at any time before or during clinical studies due to safety concerns or non-compliance. If the FDA imposes a clinical hold, studies may 
not recommence without FDA authorization and then only under terms authorized by the FDA. Accordingly, we cannot be sure that 
submission of an IND will result in the FDA allowing clinical studies to begin, or that, once begun, issues will not arise that suspend 
or terminate such studies. 

Clinical studies involve the administration of the drug or biological product candidate to healthy volunteers or patients under the 
supervision of qualified investigators, generally physicians not employed by or under the study sponsor’s control. Clinical studies are 
conducted under protocols detailing, among other things, the objectives of the clinical study, dosing procedures, subject selection and 
exclusion criteria, and the parameters to be used to monitor subject safety, including stopping rules that assure a clinical study will be 
stopped if certain adverse events should occur. Each protocol and any amendments to the protocol must be submitted to the FDA as 
part of the IND. Clinical studies must be conducted and monitored in accordance with the FDA’s regulations comprising the GCP 
requirements, including the requirement that all research subjects provide informed consent. Further, each clinical study must be 
reviewed and approved by an independent institutional review board, or IRB, at or servicing each institution at which the clinical 
study will be conducted. An IRB is charged with protecting the welfare and rights of study participants and considers such items as 
whether the risks to individuals participating in the clinical studies are minimized and are reasonable in relation to anticipated benefits. 
The IRB also approves the form and content of the informed consent that must be signed by each clinical study subject or his or her 
legal representative and must monitor the clinical study until completed. 

Human clinical studies are typically conducted in three sequential phases that may overlap or be combined: 

(cid:120) 

(cid:120) 

(cid:120) 

Phase 1. The drug or biological product is initially introduced into healthy human subjects and tested for safety. In the 
case of some products for severe or life-threatening diseases, especially when the product may be too inherently toxic to 
ethically administer to healthy volunteers, the initial human testing is often conducted in patients. 

Phase 2. The drug or biological product is evaluated in a limited patient population to identify possible adverse effects and 
safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage 
tolerance, optimal dosage and dosing schedule. 

Phase 3. Clinical studies are undertaken to further evaluate dosage, clinical efficacy, potency, and safety in an expanded 
patient population at geographically dispersed clinical study sites. These clinical studies are intended to establish the 
overall risk/benefit ratio of the product and provide an adequate basis for product labeling. 

Post-approval clinical studies, sometimes referred to as Phase 4 clinical studies, may be conducted after initial marketing 
approval. These clinical studies are used to gain additional experience from the treatment of patients in the intended therapeutic 
indication, particularly for long-term safety follow-up. The FDA recommends that sponsors observe subjects in studies of gene 
therapy products for potential gene therapy-related delayed adverse events for a 15-year period, including a minimum of five years of 
annual examinations followed by ten years of annual queries, either in person or by questionnaire, of study subjects. During all phases 
of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and 
clinical study investigators. 

Concurrent with clinical studies, companies usually complete additional animal studies and must also develop additional 

information about the physical characteristics of the drug or biological product as well as finalize a process for manufacturing the 
product in commercial quantities in accordance with GMP requirements. To help reduce the risk of the introduction of adventitious 
agents with use of biological products, the PHS Act emphasizes the importance of manufacturing control for products whose attributes 
cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product 
candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency and purity of 
the final drug or biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be 
conducted to demonstrate that the drug or biological product candidate does not undergo unacceptable deterioration over its shelf life. 

20 

 
Human gene therapy products are a new category of therapeutics, and studies of gene therapy products are subject to certain 

regulatory requirements in addition to those set forth above including certain requirements of the National Institutes of Health. 

U.S. Review and Approval Processes 

After the completion of clinical studies of a drug or biological product, FDA approval of an NDA or a BLA must be obtained 

before commercial marketing of the drug or biological product, respectively. The NDA or BLA must include results of product 
development, laboratory and animal studies, human studies, information on the manufacture and composition of the product, proposed 
labeling and other relevant information. In addition, under the Pediatric Research Equity Act, or PREA, an NDA or a BLA or 
supplement to an NDA or a BLA must contain data to assess the safety and effectiveness of the product for the claimed indications in 
all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product 
is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers. Unless otherwise required by 
regulation, PREA does not apply to any drug or biological product for an indication for which orphan designation has been granted. 
The testing and approval processes require substantial time and effort and there can be no assurance that the FDA will accept the NDA 
or BLA for filing and, even if filed, that any approval will be granted on a timely basis, if at all. 

Under the Prescription Drug User Fee Act, or PDUFA, as amended, each NDA or BLA must be accompanied by a substantial 

user fee. PDUFA also imposes an annual product fee for drugs and biologics and an annual establishment fee on facilities used to 
manufacture prescription drugs or biologics. Fee waivers or reductions are available in certain circumstances, including a waiver of 
the application fee for the first application filed by a small business. Additionally, no user fees are assessed on NDAs or BLAs for 
products designated as orphan drugs, unless the product also includes a non-orphan indication. 

Within 60 days following submission of the application, the FDA reviews an NDA or BLA submitted to determine if it is 

substantially complete before the agency accepts it for filing. The FDA may refuse to file any marketing application that it deems 
incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the NDA or 
BLA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA 
accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review of the NDA or BLA. 
The FDA reviews the application to determine, among other things, whether the proposed product is safe and potent, or effective, for 
its intended use, and has an acceptable purity profile, and whether the product is being manufactured in accordance with GMP to 
assure and preserve the product’s identity, safety, strength, quality, potency and purity. The FDA may refer applications for novel 
products or products that present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes 
clinicians and other experts, for review, evaluation and a recommendation as to whether the application should be approved and under 
what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations 
carefully when making decisions. During the product approval process, the FDA also will determine whether a Risk Evaluation and 
Mitigation Strategy, or REMS, is necessary to assure the safe use of the product. If the FDA concludes a REMS is needed, the sponsor 
of the NDA or BLA must submit a proposed REMS; the FDA will not approve the application without a REMS, if required. 

Before approving an NDA or a BLA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not 
approve the product unless it determines that the manufacturing processes and facilities are in compliance with GMP requirements and 
adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA or a 
BLA, the FDA will typically inspect one or more clinical sites to assure that the clinical studies were conducted in compliance with 
IND study requirements and GCP requirements. To assure GMP and GCP compliance, an applicant must incur significant expenditure 
of time, money and effort in the areas of training, record keeping, production, and quality control. 

Notwithstanding the submission of relevant data and information, the FDA may ultimately decide that the NDA or BLA does 

not satisfy its regulatory criteria for approval and deny approval. Data obtained from clinical studies are not always conclusive and the 
FDA may interpret data differently than we interpret the same data. If the agency decides not to approve the marketing application, the 
FDA will issue a complete response letter that usually describes all of the specific deficiencies in the application identified by the 
FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional 
clinical studies. Additionally, the complete response letter may include recommended actions that the applicant might take to place the 
application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the NDA or BLA, 
addressing all of the deficiencies identified in the letter, or withdraw the application. 

21 

 
If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the 
indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require 
that certain contraindications, warnings or precautions be included in the product labeling. The FDA may impose restrictions and 
conditions on product distribution, prescribing, or dispensing in the form of a risk management plan, or otherwise limit the scope of 
any approval. In addition, the FDA may require post-approval clinical studies, sometimes referred to as Phase 4 clinical studies, 
designed to further assess a product’s safety and effectiveness, and testing and surveillance programs to monitor the safety of 
approved products that have been commercialized. 

One of the performance goals agreed to by the FDA under the PDUFA is to complete its review of 90% of standard NDAs and 

BLAs within ten months from filing and 90% of priority NDAs and BLAs within six months from filing, whereupon a review decision 
is to be made. The FDA does not always meet its PDUFA goal dates and its review goals are subject to change from time to time. The 
review process and the PDUFA goal date may be extended by three months if the FDA requests or the application sponsor otherwise 
provides additional information or clarification regarding information already provided in the submission within the last three months 
before the PDUFA goal date. 

Fast Track Designation 

The FDA has various programs, including Fast Track, which are intended to expedite the process for reviewing drugs. Even if a 

drug qualifies for one or more of these programs, the FDA may later decide that the drug no longer meets the conditions for 
qualification. Generally, drugs that are eligible for these programs are those for serious or life-threatening conditions, those with the 
potential to address unmet medical needs, and those that offer meaningful benefits over existing treatments. For example, Fast Track is 
a process designed to expedite the FDA’s review of drugs that treat serious or life-threatening diseases or conditions and fill unmet 
medical needs. Under the Fast Track process, drugs that offer major advances in treatment or provide a treatment where no adequate 
therapy exists, may also receive priority review by the FDA, or review within six months of the filing of an NDA compared to a 
traditional review time of ten months. Although Fast Track and priority review do not affect the standards for approval of a drug, for 
Fast Track designated drugs, the FDA will also attempt to facilitate early and frequent meetings with a sponsor of a Fast Track 
designated drug, to expedite such drug’s review and development. Although FDA has granted fast track designations to TV-45070 for 
EM and to Glybera for LPLD, such designations may not result in a faster development or review time, do not increase the odds of 
approval, and may be rescinded at any time if these drug candidates do not continue to meet the qualifications for these programs. 

Orphan Drug Designation 

Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biological product intended to treat a rare 

disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the U.S., or more than 
200,000 individuals in the U.S. and for which there is no reasonable expectation that the cost of developing and making a drug or 
biological product available in the U.S. for this type of disease or condition will be recovered from sales of the product. Both TV-
45070 and Glybera have received orphan drug designation from the FDA. We have also received orphan drug designation from the 
FDA for flunarizine, a drug we are evaluating internally for the potential treatment of hemiplegic migraine. Orphan product 
designation must be requested before submitting an NDA or BLA. After the FDA grants orphan product designation, the identity of 
the therapeutic agent and its potential orphan use are disclosed publicly by the FDA. Orphan product designation does not convey any 
advantage in or shorten the duration of the regulatory review and approval process. 

If a product that has orphan designation subsequently receives the first FDA approval for such drug for the disease or condition 

for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve 
any other applications to market the same drug or biological product for the same indication for seven years, except in limited 
circumstances, such as a showing of clinical superiority to the product with orphan exclusivity. Competitors, however, may receive 
approval of different products for the indication for which the orphan product has exclusivity or obtain approval for the same product 
but for a different indication for which the orphan product has exclusivity. Orphan product exclusivity also could block the approval 
of one of our products for seven years if a competitor obtains approval of the same product as defined by the FDA or if our product 
candidate is determined to be contained within the competitor’s product for the same indication or disease. If a drug or biological 
product designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be 
entitled to orphan product exclusivity. Orphan drug status in the EU has similar, but not identical, benefits, including up to ten years of 
exclusivity.  

22 

 
Post-Approval Requirements 

Maintaining substantial compliance with applicable federal, provincial, state, and local statutes and regulations requires the 

expenditure of substantial time and financial resources. Rigorous and extensive FDA regulation of drug and biological products 
continues after approval, particularly with respect to GMP. We will rely, and expect to continue to rely, on third parties for the 
production of clinical and commercial quantities of any products that we may commercialize. Manufacturers of our products are 
required to comply with applicable requirements in the GMP regulations, including quality control and quality assurance and 
maintenance of records and documentation. Other post-approval requirements applicable to drug and biological products, include 
reporting of GMP deviations that may affect the identity, potency, purity and overall safety of a distributed product, record-keeping 
requirements, reporting of adverse effects, reporting updated safety and efficacy information, and complying with electronic record 
and signature requirements. After an NDA or BLA is approved, the product also may be subject to official lot release. As part of the 
manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for 
distribution. If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the 
FDA together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the 
manufacturer’s tests performed on the lot. The FDA also may perform certain confirmatory tests on lots of some products before 
releasing the lots for distribution by the manufacturer. In addition, the FDA conducts laboratory research related to the regulatory 
standards on the safety, purity, potency, and effectiveness of drug and biological products. 

We also must comply with the FDA’s advertising and promotion requirements, such as those related to direct-to-consumer 

advertising, the prohibition on promoting products for uses or in patient populations that are not described in the product’s approved 
labeling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the 
internet. Discovery of previously unknown problems or the failure to comply with the applicable regulatory requirements may result 
in restrictions on the marketing of a product or withdrawal of the product from the market as well as possible civil or criminal 
sanctions. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval 
process or after approval, may subject an applicant or manufacturer to administrative or judicial civil or criminal sanctions and adverse 
publicity. FDA sanctions could include refusal to approve pending applications, withdrawal of an approval, clinical hold, warning or 
untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of 
government contracts, mandated corrective advertising or communications with doctors, debarment, restitution, disgorgement of 
profits, or civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us. 

Drug and biological product manufacturers and other entities involved in the manufacture and distribution of approved drug or 

biological products are required to register their establishments with the FDA and certain state agencies, and are subject to periodic 
unannounced inspections by the FDA and certain state agencies for compliance with GMPs and other laws. Accordingly, 
manufacturers must continue to expend time, money, and effort in the area of production and quality control to maintain GMP 
compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an 
approved NDA or BLA, including withdrawal of the product from the market. In addition, changes to the manufacturing process or 
facility generally require prior FDA approval before being implemented and other types of changes to the approved product, such as 
adding new indications and additional labeling claims, are also subject to further FDA review and approval. 

U.S. Patent Term Restoration and Marketing Exclusivity 

Depending upon the timing, duration and specifics of the FDA approval of the use of our product candidates, some of our U.S. 
patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, 
commonly referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to 
five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent 
term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent 
term restoration period is generally one-half the time between the effective date of an IND and the submission date of an NDA or 
BLA plus the time between the submission date of an NDA or BLA and the approval of that application. Only one patent applicable to 
an approved product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the 
patent. The U.S. Patent and Trademark Office, in consultation with the FDA, reviews and approves the application for any patent term 
extension or restoration. 

Under the Hatch-Waxman Amendments, a drug product containing a new chemical entity as its active ingredient is entitled to 

five years of market exclusivity, and a product for which the sponsor is required to generate new clinical data is entitled to three years 
of market exclusivity. A drug or biological product can also obtain pediatric market exclusivity in the U.S. Pediatric exclusivity, if 
granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of other 
exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an 
FDA-issued “Written Request” for such a study. 

23 

 
The Biologics Price Competition and Innovation Act of 2009 created an abbreviated approval pathway for biological products 

shown to be similar to, or interchangeable with, an FDA-licensed reference biological product. Biosimilarity, which requires that there 
be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and 
potency, can be shown through analytical studies, animal studies, and a clinical study or studies. Interchangeability requires that a 
product is biosimilar to the reference product and the product must demonstrate that it can be expected to produce the same clinical 
results as the reference product and, for products administered multiple times, the biologic and the reference biologic may be switched 
after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of 
the reference biologic. However, complexities associated with the larger, and often more complex, structure of biological products, as 
well as the process by which such products are manufactured, pose significant hurdles to implementation that are still being worked 
out by the FDA. 

A reference biologic is granted 12 years of exclusivity from the time of first licensure of the reference product. The first biologic 

product submitted under the abbreviated approval pathway that is determined to be interchangeable with the reference product has 
exclusivity against other biologics submitted under the abbreviated approval pathway for the lesser of (i) one year after the first 
commercial marketing, (ii) 18 months after approval if there is no legal challenge, (iii) 18 months after the resolution in the applicant’s 
favor of a lawsuit challenging the biologics’ patents if an application has been submitted, or (iv) 42 months after the application has 
been approved if a lawsuit is ongoing within the 42-month period. 

Additional Regulation 

In addition to the foregoing, provincial, state and federal U.S. and Canadian laws regarding environmental protection and 
hazardous substances affect our business. These and other laws govern our use, handling and disposal of various biological, chemical 
and radioactive substances used in, and wastes generated by, our operations. If our operations result in contamination of the 
environment or expose individuals to hazardous substances, we could be liable for damages and governmental fines. We believe that 
we are in material compliance with applicable environmental laws and that continued compliance therewith will not have a material 
adverse effect on our business. We cannot predict, however, how changes in these laws may affect our future operations. 

Global Anti-Corruption Laws 

The U.S. Foreign Corrupt Practices Act and the Canadian Corruption of Foreign Public Officials Act, the U.S. Travel Act, the 

OECD Anti-Bribery Convention, Title 18 United States Code section 201, and any other applicable domestic or foreign anti-
corruption or anti-bribery laws to which we are subject prohibit corporations and individuals from engaging in certain activities to 
obtain or retain business or to influence a person working in an official capacity. It is illegal to pay, offer to pay or authorize the 
payment of anything of value to any foreign government official, government staff member, political party or political candidate in an 
attempt to obtain or retain business or to otherwise influence a person working in an official capacity. We may also be held liable for 
the acts of our third party agents under the U.S. Foreign Corrupt Practices Act and Canadian Corruption of Foreign Public Officials 
Act and other applicable anti-corruption and anti-bribery laws. Noncompliance with these laws could subject us to investigations, 
sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and 
criminal penalties or injunctions, suspension or debarment from contracting with certain persons, the loss of export privileges, 
whistleblower complaints, reputational harm, adverse media coverage, and other collateral consequences. Any investigations, actions 
or sanctions or other previously mentioned harm could have a material negative effect on our business, operating results and financial 
condition. 

Government Regulation Outside of the U.S. 

In addition to regulations in the U.S., we will be subject to a variety of regulations in other jurisdictions governing, among other 

things, clinical studies and any commercial sales and distribution of our products. 

Whether or not we obtain FDA approval for a product, we must obtain the requisite approvals from regulatory authorities in 

foreign countries prior to the commencement of clinical studies or marketing of the product in those countries. Certain countries 
outside of the U.S. have a similar process that requires the submission of a clinical study application much like the IND prior to the 
commencement of human clinical studies. In the EU, for example, a CTA must be submitted to each country’s national health 
authority and an independent ethics committee, much like the FDA and the IRB, respectively. Once the CTA is approved in 
accordance with a country’s requirements, clinical study development may proceed. 

The requirements and process governing the conduct of clinical studies, product licensing, coverage, pricing and reimbursement 

vary from country to country. In all cases, the clinical studies are conducted in accordance with GCP and the applicable regulatory 
requirements and the ethical principles that have their origin in the Declaration of Helsinki. 

24 

 
To obtain regulatory approval of an investigational drug or biological product under EU regulatory systems, we must submit a 
marketing authorization application, or MAA. The application used to file the NDA or BLA in the U.S. is similar to that required in 
the EU, with the exception of, among other things, country-specific document requirements. The EU also provides opportunities for 
market exclusivity. For example, in the EU, upon receiving marketing authorization, new chemical entities generally receive eight 
years of data exclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities 
in the EU from referencing the innovator’s data to assess a generic application. During the additional two-year period of market 
exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic product 
can be marketed until the expiration of the market exclusivity. However, there is no guarantee that a product will be considered by the 
EU’s regulatory authorities to be a new chemical entity, and products may not qualify for data exclusivity. Products receiving orphan 
designation in the EU can receive ten years of market exclusivity, during which time no similar medicinal product for the same 
indication may be placed on the market. An orphan product can also obtain an additional two years of market exclusivity in the EU for 
pediatric studies. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan 
indications. 

The criteria for designating an “orphan medicinal product” in the EU are similar in principle to those in the U.S. Under Article 3 

of Regulation (EC) 141/2000, a medicinal product may be designated as orphan if (1) it is intended for the diagnosis, prevention or 
treatment of a life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more than five in 10,000 
persons in the EU when the application is made, or (b) the product, without the benefits derived from orphan status, would not 
generate sufficient return in the EU to justify investment; and (3) there exists no satisfactory method of diagnosis, prevention or 
treatment of such condition authorized for marketing in the EU, or if such a method exists, the product will be of significant benefit to 
those affected by the condition, as defined in Regulation (EC) 847/2000. Orphan medicinal products are eligible for financial 
incentives such as reduction of fees or fee waivers and are, upon grant of a marketing authorization, entitled to ten years of market 
exclusivity for the approved therapeutic indication. The application for orphan drug designation must be submitted before the 
application for marketing authorization. The applicant will receive a fee reduction for the marketing authorization application if the 
orphan drug designation has been granted, but not if the designation is still pending at the time the marketing authorization is 
submitted. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval 
process. Glybera has received orphan drug designation for the treatment of LPLD in the EU. 

The 10-year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no 

longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of 
market exclusivity. Additionally, marketing authorization may be granted to a similar product for the same indication at any time if: 

(cid:120) 

(cid:120) 

(cid:120) 

the second applicant can establish that its product, although similar, is safer, more effective or otherwise clinically 
superior; 

the applicant consents to a second orphan medicinal product application; or 

the applicant cannot supply enough orphan medicinal product. 

For other countries outside of the EU, such as countries in Eastern Europe, Latin America or Asia, the requirements governing 

the conduct of clinical studies, product licensing, coverage, pricing and reimbursement vary from country to country. In all cases, 
again, the clinical studies are conducted in accordance with GCP and the applicable regulatory requirements and the ethical principles 
that have their origin in the Declaration of Helsinki. 

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines, 

suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution. 

Pharmaceutical Coverage, Pricing and Reimbursement 

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain 

regulatory approval. In the U.S. and markets in other countries, sales of any products for which we receive regulatory approval for 
commercial sale will depend, in part, on the availability of coverage and adequate reimbursement from third-party payers. Third-party 
payers include government programs such as Medicare or Medicaid, managed care plans, private health insurers, and other 
organizations. These third-party payers may deny coverage or reimbursement for a product or therapy in whole or in part if they 
determine that the product or therapy was not medically appropriate or necessary. Third-party payers may attempt to control costs by 
limiting coverage to specific drug products on an approved list, or formulary, which might not include all of the FDA-approved drug 
products for a particular indication, and by limiting the amount of reimbursement for particular procedures or drug treatments. 

25 

 
The cost of pharmaceuticals and devices continues to generate substantial governmental and third party payer interest. We 
expect that the pharmaceutical industry will experience pricing pressures due to the trend toward managed healthcare, the increasing 
influence of managed care organizations and additional legislative proposals. Third-party payers are increasingly challenging the price 
and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. 
We may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of 
our products, in addition to the costs required to obtain the FDA approvals. Our product candidates may not be considered medically 
necessary or cost-effective. A payer’s decision to provide coverage for a drug product does not imply that an adequate reimbursement 
rate will be approved. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to 
realize an appropriate return on our investment in product development. 

Some third-party payers also require pre-approval of coverage for new or innovative devices or drug therapies before they will 

reimburse healthcare providers who use such therapies. While we cannot predict whether any proposed cost-containment measures 
will be adopted or otherwise implemented in the future, these requirements or any announcement or adoption of such proposals could 
have a material adverse effect on our ability to obtain adequate prices for our product candidates and to operate profitably. 

In international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have 

instituted price ceilings on specific products and therapies. There can be no assurance that our products will be considered medically 
reasonable and necessary for a specific indication, that our products will be considered cost-effective by third-party payers, that 
coverage or an adequate level of reimbursement will be available or that the third-party payers’ reimbursement policies will not 
adversely affect our ability to sell our products profitably. 

Healthcare Reform 

In the U.S. and foreign jurisdictions, there have been a number of legislative and regulatory changes to the healthcare system 
that could affect our future results of operations. In particular, there have been and continue to be a number of initiatives at the U.S. 
federal and state levels that seek to reduce healthcare costs. 

In the U.S., the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or the Medicare Modernization Act, 

changed the way Medicare covers and pays for pharmaceutical products. The Medicare Modernization Act expanded Medicare 
coverage for drug purchases by the elderly by establishing Medicare Part D and introduced a new reimbursement methodology based 
on average sales prices for physician administered drugs under Medicare Part B. In addition, this legislation provided authority for 
limiting the number of drugs that will be covered in any therapeutic class under the new Medicare Part D program. Cost reduction 
initiatives and other provisions of this legislation could decrease the coverage and reimbursement rate that we receive for any of our 
approved products. While the Medicare Modernization Act applies only to drug benefits for Medicare beneficiaries, private payers 
often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Therefore, any reduction in 
reimbursement that results from the Medicare Modernization Act may result in a similar reduction in payments from private payers. 

In March 2010, the President signed into law the Patient Protection and Affordable Care Act, as amended, or PPACA, a 

sweeping law intended to broaden access to health insurance, reduce or constrain the growth of healthcare spending, enhance remedies 
against healthcare fraud and abuse, add new transparency requirements for healthcare and health insurance industries, impose new 
taxes and fees on pharmaceutical and medical device manufacturers and impose additional health policy reforms. Among other things, 
PPACA revises the definition of “average manufacturer price” for reporting purposes, which could increase the amount of Medicaid 
drug rebates to states. Further, the new law imposes a significant annual fee on companies that manufacture or import branded 
prescription drug products. Substantial new provisions affecting compliance have also been enacted, which may affect our business 
practices with healthcare practitioners and a significant number of provisions are not yet, or have only recently become, effective. 
Although it is too early to determine the full effect of PPACA, the new law appears likely to continue the downward pressure on 
pharmaceutical pricing, especially under the Medicare program, and may also increase our regulatory burdens and operating costs. 

In addition, other legislative changes have been proposed and adopted since PPACA was enacted. These new laws may result in 

reductions in Medicare and other healthcare funding, which could have a material adverse effect on our customers and accordingly, 
our financial operations. 

We expect that PPACA, as well as other healthcare reform measures that have been and may be adopted in the future, may 
result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any approved product, 
and could seriously harm our future revenue. Any reduction in reimbursement from Medicare or other government programs may 
result in a similar reduction in payments from private payers. The implementation of cost containment measures or other healthcare 
reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products. 

26 

 
The Trump administration and Congress are also expected to attempt broad sweeping changes to the current health care laws. 
We face uncertainties that might result from modification or repeal of any of the provisions of the PPACA, including as a result of 
current and future executive orders and legislative actions. The impact of those changes on us and the pharmaceutical industry as a 
whole is currently unknown. Any changes to the PPACA are likely to have an impact on our results of operations, and may have a 
material adverse effect on our result of operations. We cannot predict what other healthcare programs and regulations will ultimately 
be implemented at the federal or state level or the effect of any future legislation or regulation in the United States may have on our 
business. 

In addition, different pricing and reimbursement schemes exist in other countries. In the European Community, governments 

influence the price of pharmaceutical products through their pricing and reimbursement rules and control of national healthcare 
systems that fund a large part of the cost of those products to consumers. Some jurisdictions operate positive and negative list systems 
under which products may be marketed only once a reimbursement price has been agreed upon. Some of these countries may require, 
as condition of obtaining reimbursement or pricing approval, the completion of clinical trials that compare the cost-effectiveness of a 
particular product candidate to currently available therapies. Other member states allow companies to fix their own prices for 
medicines, but monitor and control company profits. The downward pressure on healthcare costs in general, particularly prescription 
drugs, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in 
some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country. 

Other Healthcare Laws and Compliance Requirements 

In the U.S., the research, manufacturing, distribution, sale and promotion of drug products and medical devices are potentially 

subject to regulation by various federal, provincial, state and local authorities in addition to the FDA, including the Centers for 
Medicare & Medicaid Services, other divisions of the U.S. Department of Health and Human Services (e.g., the Office of Inspector 
General), the U.S. Department of Justice, state Attorneys General, and other state and local government agencies. For example, sales, 
marketing and scientific/educational grant programs must comply with fraud and abuse laws such as the federal Anti-Kickback 
Statute, as amended, the federal False Claims Act, as amended, and similar state laws. Pricing and rebate programs must comply with 
the Medicaid Drug Rebate Program requirements of the Omnibus Budget Reconciliation Act of 1990, as amended, and the Veterans 
Health Care Act of 1992, as amended. If products are made available to authorized users of the Federal Supply Schedule of the 
General Services Administration, additional laws and requirements apply. All of these activities are also potentially subject to federal 
and state consumer protection and unfair competition laws. 

The federal Anti-Kickback Statute prohibits any person, including a prescription drug manufacturer (or a party acting on its 
behalf), from knowingly and willfully soliciting, receiving, offering or providing remuneration, directly or indirectly, to induce or 
reward either the referral of an individual, or the furnishing, recommending, or arranging for a good or service, for which payment 
may be made under a federal healthcare program such as the Medicare and Medicaid programs. This statute has been interpreted to 
apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on 
the other. The term “remuneration” is not defined in the federal Anti-Kickback Statute and has been broadly interpreted to include 
anything of value, including for example, gifts, discounts, the furnishing of supplies or equipment, credit arrangements, payments of 
cash, waivers of payments, ownership interests and providing anything at less than its fair market value. Although there are a number 
of statutory exemptions and regulatory safe harbors protecting certain business arrangements from prosecution, the exemptions and 
safe harbors are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchasing or recommending 
may be subject to scrutiny if they do not qualify for an exemption or safe harbor. Our practices may not in all cases meet all of the 
criteria for safe harbor protection from federal Anti-Kickback Statute liability. The reach of the Anti-Kickback Statute was broadened 
by the recently enacted PPACA, which, among other things, amends the intent requirement of the federal Anti-Kickback Statute such 
that a person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it in order to have 
committed a violation. In addition, the PPACA provides that the government may assert that a claim including items or services 
resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False 
Claims Act (discussed below) or the civil monetary penalties statute, which imposes fines against any person who is determined to 
have presented or caused to be presented claims to a federal healthcare program that the person knows or should know is for an item 
or service that was not provided as claimed or is false or fraudulent. Additionally, many states have adopted laws similar to the federal 
Anti-Kickback Statute, and some of these state prohibitions apply to referral of patients for healthcare items or services reimbursed by 
any third-party payer, not only the Medicare and Medicaid programs in at least some cases, and do not contain safe harbors. 

27 

 
The federal False Claims Act imposes liability on any person or entity that, among other things, knowingly presents, or causes 
to be presented, a false or fraudulent claim for payment by a federal healthcare program. The qui tam provisions of the False Claims 
Act allow a private individual to bring civil actions on behalf of the federal government alleging that the defendant has submitted a 
false claim to the federal government, and to share in any monetary recovery. In recent years, the number of suits brought by private 
individuals has increased dramatically. In addition, various states have enacted false claims laws analogous to the False Claims Act. 
Many of these state laws apply where a claim is submitted to any third-party payer and not merely a federal healthcare program. There 
are many potential bases for liability under the False Claims Act. Liability arises, primarily, when an entity knowingly submits, or 
causes another to submit, a false claim for reimbursement to the federal government. The False Claims Act has been used to assert 
liability on the basis of inadequate care, kickbacks and other improper referrals, improperly reported government pricing metrics such 
as Best Price or Average Manufacturer Price, improper use of Medicare numbers when detailing the provider of services, improper 
promotion of off-label uses (i.e., uses not expressly approved by FDA in a drug’s label), and allegations as to misrepresentations with 
respect to the services rendered. Our future activities relating to the reporting of discount and rebate information and other information 
affecting federal, provincial, state and third party reimbursement of our products, and the sale and marketing of our products and our 
service arrangements or data purchases, among other activities, may be subject to scrutiny under these laws. We are unable to predict 
whether we would be subject to actions under the False Claims Act or a similar state law, or the impact of such actions. However, the 
cost of defending such claims, as well as any sanctions imposed, could adversely affect our financial performance. Also, the Health 
Insurance Portability and Accountability Act of 1996, or HIPAA, created several new federal crimes, including healthcare fraud, and 
false statements relating to healthcare matters. The healthcare fraud statute prohibits knowingly and willfully executing a scheme to 
defraud any healthcare benefit program, including private third-party payers. The false statements statute prohibits knowingly and 
willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in 
connection with the delivery of or payment for healthcare benefits, items or services. 

In addition, we may be subject to, or our marketing activities may be limited by, data privacy and security regulation by both the 

federal government and the states in which we conduct our business. For example, HIPAA and its implementing regulations 
established uniform federal standards for certain “covered entities” (healthcare providers, health plans and healthcare clearinghouses) 
governing the conduct of certain electronic healthcare transactions and protecting the security and privacy of protected health 
information. The American Recovery and Reinvestment Act of 2009, commonly referred to as the economic stimulus package, 
included expansion of HIPAA’s privacy and security standards called the Health Information Technology for Economic and Clinical 
Health Act, or HITECH. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to 
“business associates”—independent contractors or agents of covered entities that create, receive, maintain, or transmit protected health 
information in connection with providing a service for or on behalf of a covered entity. HITECH also increased the civil and criminal 
penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys 
general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek 
attorney’s fees and costs associated with pursuing federal civil actions. 

There are also an increasing number of state “sunshine” laws that require manufacturers to make reports to states on pricing and 

marketing information. Several states have enacted legislation requiring pharmaceutical companies to, among other things, establish 
marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, 
clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare 
entities from providing certain physician prescribing data to pharmaceutical companies for use in sales and marketing, and to prohibit 
certain other sales and marketing practices. In addition, beginning in 2013, a similar federal requirement began requiring 
manufacturers to track and report to the federal government certain payments and other transfers of value made to physicians and 
other healthcare professionals and teaching hospitals and ownership or investment interests held by physicians and their immediate 
family members. The federal government discloses the reported information on a publicly available website. These laws may affect 
our sales, marketing, and other promotional activities by imposing administrative and compliance burdens on us. If we fail to track 
and report as required by these laws or otherwise comply with these laws, we could be subject to the penalty provisions of the 
pertinent state and federal authorities. 

Because of the breadth of these laws and the narrowness of available statutory and regulatory exemptions, it is possible that 
some of our business activities could be subject to challenge under one or more of such laws. If our operations are found to be in 
violation of any of the federal and state laws described above or any other governmental regulations that apply to us, we may be 
subject to penalties, including criminal and significant civil monetary penalties, damages, fines, imprisonment, exclusion from 
participation in government healthcare programs, injunctions, recall or seizure of products, total or partial suspension of production, 
denial or withdrawal of pre-marketing product approvals, private qui tam actions brought by individual whistleblowers in the name of 
the government or refusal to allow us to enter into supply contracts, including government contracts, and the curtailment or 
restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. 
To the extent that any of our products are sold in a foreign country, we may be subject to similar foreign laws and regulations, which 
may include, for instance, applicable post-approval requirements, including safety surveillance, anti-fraud and abuse laws, and 
implementation of corporate compliance programs and reporting of payments or transfers of value to healthcare professionals. 

28 

 
Environmental Matters 

Our operations require the use of hazardous materials (including biological materials) which subject us to a variety of federal, 

provincial and local environmental and safety laws and regulations. Some of the regulations under the current regulatory structure 
provide for strict liability, holding a party potentially liable without regard to fault or negligence. We could be held liable for damages 
and fines as a result of our, or someone else’s, business operations should contamination of the environment or individual exposure to 
hazardous substances occur. We cannot predict how changes in laws or development of new regulations will affect our business 
operations or the cost of compliance. 

Employees 

As of December 31, 2016, we had 94 employees, including 88 full-time employees. Of our employees, 61 were primarily engaged 
in research and development, and 30 of whom hold a Ph.D. or M.D. (or equivalent) degree. None of our employees are represented by a 
labor union. We have not experienced any work stoppages, and we consider our relations with our employees to be good. 

Research and Development  

We have committed, and expect to continue to commit, significant resources to developing new product candidates. We have 

assembled an experienced research and development team with scientific and clinical development personnel. Our research and 
development expenses for the years ended December 31, 2016, 2015, and 2014 were $19.8 million, $15.2 million, and $11.8 million, 
respectively. 

Manufacturing 

We currently rely, and expect to continue to rely, on third parties and our collaborators for the manufacture of our product 
candidates for preclinical and clinical testing, as well as for commercial manufacture if our product candidates receive marketing 
approval. Accordingly, we have not internally developed any manufacturing facilities or hired related personnel. 

To date, we have obtained materials for our product candidates from multiple third-party manufacturers. We believe that all of 

the materials required for the manufacture of our product candidates can be obtained from more than one source. However, the 
manufacturing processes for each of our product candidates, which include large and small-molecules, vary and sourcing adequate 
supplies may be made more difficult depending on the type of product candidate involved. Our small-molecule product candidates 
generally can be manufactured in reliable and reproducible synthetic processes from readily available starting materials. This 
chemistry generally is amenable to scale-up and does not require unusual equipment in the manufacturing process. 

Corporate Information 

We were incorporated in the Province of British Columbia on November 5, 1996 under the predecessor to the Business 
Corporations Act (British Columbia) under the name “Xenon Bioresearch Inc.” We continued from British Columbia to the federal 
jurisdiction pursuant to Section 187 of the Canada Business Corporations Act, or the CBCA, on May 17, 2000 and concurrently 
changed our name to “Xenon Genetics Inc.” We registered as an extra-provincial company in British Columbia on July 10, 2000 and 
changed our name to “Xenon Pharmaceuticals Inc.” on August 24, 2004. We have one wholly-owned subsidiary as at December 31, 
2016, Xenon Pharmaceuticals USA Inc., which was incorporated in Delaware on December 2, 2016. Our principal executive offices 
are located at 200 – 3650 Gilmore Way, Burnaby, British Columbia, Canada V5G 4W8, and our telephone number is (604) 484-3300.

Item 1A.  Risk Factors 

You should carefully consider the following risk factors, in addition to the other information contained in this report, including 
the section of this report captioned “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and 
our financial statements and related notes. If any of the events described in the following risk factors and the risks described 
elsewhere in this report occurs, our business, operating results and financial condition could be seriously harmed. This report on 
Form 10-K also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially 
from those anticipated in the forward-looking statements as a result of factors that are described below and elsewhere in this report.  

Risks Related to Our Financial Condition and Capital Requirements 

We have incurred significant losses since our inception and anticipate that we will continue to incur significant losses for the 

foreseeable future. 

We are a clinical-stage biotechnology company and, other than the years ended December 31, 2014 and 2013, we have recorded 

net losses in each annual reporting period since inception in 1996, and we do not expect to have sustained profitability for the 
foreseeable future. We had net losses of $23.0 million for the year ended December 31, 2016 and an accumulated deficit of $142.7 
million as of December 31, 2016, which were driven by expenses incurred in connection with our research programs and from general 
and administrative costs associated with our operations. 

We have devoted most of our financial resources to research and development, including our clinical and preclinical 
development activities. To date, we have financed our operations through the sale of equity securities, funding received from our 
licensees and collaborators and, to a lesser extent, government funding. Other than royalties we are eligible to receive from sales of 
Glybera under our license to uniQure Biopharma B.V., or uniQure, which we do not expect to be significant, we have not generated 
any royalty revenue from product sales and our product candidates will require substantial additional investment before they will 
provide us with any product royalty revenue. 

We expect to incur significant expenses and increasing operating losses for the foreseeable future as we:

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

continue our research and preclinical and clinical development of our product candidates; 

expand the scope of our clinical studies for our current and prospective product candidates; 

initiate additional preclinical, clinical or other studies for our product candidates, including under our collaboration 
agreements; 

change or add additional manufacturers or suppliers; 

seek regulatory and marketing approvals for any of our product candidates that successfully complete clinical studies; 

seek to identify and validate additional product candidates; 

acquire or in-license other product candidates and technologies; 

make milestone or other payments under our in-license agreements including, without limitation, our agreements with the 
University of British Columbia, or UBC, and the Memorial University of Newfoundland; 

maintain, protect and expand our intellectual property portfolio; 

30 

 
 
 
 
(cid:120) 

(cid:120) 

(cid:120) 

establish a sales, marketing and distribution infrastructure to commercialize any products for which we or one of our 
collaborators may obtain marketing approval, and for which we have maintained commercial rights; 

create additional infrastructure to support our operations and our product development and planned future 
commercialization efforts; and 

experience any delays or encounter issues with any of the above. 

Our expenses could increase beyond expectations for a variety of reasons, including if we are required by the U.S. Food and 

Drug Administration, or FDA, the European Medicines Agency, or EMA, or other regulatory agencies, domestic or foreign, to 
perform clinical and other studies in addition to those that we currently anticipate. Our prior losses, combined with expected future 
losses, have had and will continue to have an adverse effect on our shareholders’ equity. 

Other than royalties we are eligible to receive from sales of Glybera, we have not generated any royalty revenue from product 

sales and may never become profitable on a U.S. GAAP basis. 

Our ability to generate meaningful revenue and achieve profitability on a U.S. GAAP basis depends on our ability, alone or with 
strategic collaborators, to successfully complete the development of, and obtain the regulatory approvals necessary to commercialize, 
our product candidates. Substantially all of our revenue since inception has consisted of upfront and milestone payments associated 
with our collaboration and license agreements. Revenue from these agreements is dependent on successful development of our product 
candidates by us or our collaborators. Other than royalties we are eligible to receive from sales of Glybera under our license to 
uniQure, we have not generated any royalty revenue from product sales, and do not otherwise anticipate generating revenue from 
product sales for the foreseeable future, if ever. Commercial sales of Glybera commenced in November 2015, but we do not expect to 
receive significant revenue from these sales. If any of our product candidates fail in clinical trials or do not gain regulatory approval, 
or if any of our future products, if any, once approved, fail to achieve market acceptance or adequate market share, we may never 
become profitable. Although we were profitable for the years ended December 31, 2014 and 2013, we may not be able to sustain 
profitability in subsequent periods. Our ability to generate future revenue from product sales depends heavily on our success, and the 
success of our collaborators, in:

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

completing research, preclinical and clinical development of our product candidates; 

seeking and obtaining regulatory and marketing approvals for product candidates for which we complete clinical studies; 

commercializing products for which we obtain regulatory and marketing approval, either with a collaborator or, if 
launched independently, by establishing sales, marketing and distribution infrastructure; 

negotiating favorable terms in any collaboration, licensing or other arrangements into which we may enter; 

obtaining market acceptance of products for which we obtain regulatory and marketing approval as therapies; 

addressing any competing technological and market developments; 

establishing and maintaining supply and manufacturing relationships with third parties that can provide adequate (in 
amount and quality) products and services to support clinical development and the market demand for any approved 
products in the future; 

developing sustainable, scalable, reproducible, and transferable manufacturing processes for any of our products approved 
in the future; 

maintaining, protecting, expanding and enforcing our portfolio of intellectual property rights, including patents, trade 
secrets and know-how; 

implementing additional internal systems and infrastructure, as needed; and 

attracting, hiring and retaining qualified personnel. 

The scope of our future revenue will also depend upon the size of any markets in which our product candidates receive approval 

and the availability of insurance coverage and the availability and amount of reimbursement from third-party payers for Glybera and 
future products, if any. If we are unable to achieve sufficient revenue to become profitable and remain so, our financial condition and 
operating results will be negatively impacted, and our market price might be harmed. 

31 

 
We will likely need to raise additional funding, which may not be available on acceptable terms, if at all. Failure to obtain this 

necessary capital when needed may force us to delay, limit or terminate our product development efforts or other operations. 

Since our inception, we have dedicated most of our resources to the discovery and development of our proprietary preclinical 
and clinical product candidates, and we expect to continue to expend substantial resources doing so for the foreseeable future. These 
expenditures will include costs associated with research and development, manufacturing of product candidates and products approved 
for sale, conducting preclinical experiments and clinical trials and obtaining and maintaining regulatory approvals, as well as 
commercializing any products later approved for sale. During the year ended December 31, 2016, we incurred approximately $19.8 
million of costs associated with research and development, exclusive of costs incurred by our collaborators in developing our product 
candidates. 

Our current cash and cash equivalents and marketable securities are not expected to be sufficient to complete clinical 
development of any of our product candidates and prepare for commercializing any product candidate which receives regulatory 
approval. Accordingly, we will likely require substantial additional capital to continue our clinical development and potential 
commercialization activities. Our future capital requirements depend on many factors, including but not limited to: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

the number and characteristics of the future product candidates we pursue either from our internal research efforts or 
through acquiring or in-licensing other product candidates or technologies; 

the scope, progress, results and costs of independently researching and developing any of our future product candidates, 
including conducting preclinical research and clinical trials; 

whether our existing collaborations continue to generate substantial milestone payments and, ultimately, royalties on 
future approved products for us; 

the timing of, and the costs involved in, obtaining regulatory approvals for any future product candidates we develop 
independently; 

the cost of future commercialization activities, including activities required pursuant to our option to co-promote TV-
45070, if exercised by us, and the cost of commercializing any future products we develop independently that are 
approved for sale; 

the cost of manufacturing our future product candidates and products, if any; 

our ability to maintain existing collaborations and to establish new collaborations, licensing or other arrangements and the 
financial terms of such agreements; 

the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patents, including litigation 
costs and the outcome of such litigation; and 

the timing, receipt and amount of sales of, or royalties on, Glybera, and our future products, if any. 

We are unable to estimate the funds we will actually require to complete research and development of our product candidates or 

the funds required to commercialize any resulting product in the future. 

Based on our research and development plans and our timing expectations related to the progress of our programs, we expect 

that our existing cash and cash equivalents and marketable securities as of the date of this report and research funding that we expect 
to receive under our existing collaborations, will enable us to fund our operating expenses and capital expenditure requirements for at 
least the next 12 to 24 months. 

Our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional funds 

sooner than planned, through public or private equity or debt financings, government or other third-party funding, marketing and 
distribution arrangements and other collaborations, strategic alliances and licensing arrangements or a combination of these 
approaches. Raising funds in the future may present additional challenges and future financing may not be available in sufficient 
amounts or on terms acceptable to us, if at all. 

32 

 
Raising additional capital may cause dilution to our existing shareholders, restrict our operations or require us to relinquish 

rights to our technologies or product candidates. 

The terms of any financing arrangements we enter into may adversely affect the holdings or the rights of our shareholders and 
the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of 
our common shares to decline. The sale of additional equity or convertible securities would dilute all of our shareholders. For 
example, in September 2016, we sold 3,450,000 of our common shares at a price to the public of $7.50 per common share pursuant to 
our existing shelf registration statement on Form S-3 and corresponding Canadian base shelf prospectus. The incurrence of 
indebtedness would result in increased fixed payment obligations and, potentially, the imposition of restrictive covenants. Those 
covenants may include limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license 
intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. We could 
also be required to seek funds through arrangements with collaborators or otherwise at an earlier stage than otherwise would be 
desirable resulting in the loss of rights to some of our product candidates or other unfavorable terms, any of which may have a 
material adverse effect on our business, operating results and prospects. In addition, any additional fundraising efforts may divert our 
management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product 
candidates. 

Unstable market and economic conditions may have serious adverse consequences on our business and financial condition. 

Global credit and financial markets experienced extreme disruptions at various points over the last decade, characterized by 

diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in 
unemployment rates, and uncertainty about economic stability. If another such disruption in credit and financial markets and 
deterioration of confidence in economic conditions occurs, our business may be adversely affected. If the equity and credit markets 
were to deteriorate significantly in the future, it may make any necessary debt or equity financing more difficult to complete, more 
costly, and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material 
adverse effect on our growth strategy, financial performance and common share price and could require us to delay or abandon 
development or commercialization plans. In addition, there is a risk that one or more of our current collaborators, service providers, 
manufacturers and other partners would not survive or be able to meet their commitments to us under such circumstances, which could 
directly affect our ability to attain our operating goals on schedule and on budget. 

We are subject to risks associated with currency fluctuations which could impact our results of operations.  

As of December 31, 2016, approximately 44% of our cash and cash equivalents and marketable securities was denominated in 
Canadian dollars. Historically, the majority of our operating expenses have been denominated in Canadian dollars and the majority of 
our revenue has been denominated in U.S. dollars.  

Prior to December 31, 2014, our functional currency was the Canadian dollar. On January 1, 2015, our functional currency 
changed from the Canadian dollar to the U.S. dollar based on our analysis of the changes in the primary economic environment in 
which we operate. As a result, changes in the exchange rate between the Canadian dollar and the U.S. dollar could materially impact 
our reported results of operations and distort period to period comparisons. In particular, to the extent that foreign currency-
denominated (i.e., non-U.S. dollar) monetary assets do not equal the amount of our foreign currency denominated monetary liabilities, 
foreign currency gains or losses could arise and materially impact our financial statements. As a result of such foreign currency 
fluctuations, it could be more difficult to detect underlying trends in our business and results of operations. In addition, to the extent 
that fluctuations in currency exchange rates cause our results of operations to differ from our expectations or the expectations of our 
investors, the market price of our common shares could be adversely affected. 

From time to time, we may engage in exchange rate hedging activities in an effort to mitigate the impact of exchange rate 

fluctuations. For example, we maintain a natural currency hedge against fluctuations in the U.S./Canadian foreign exchange rate by 
matching the amount of U.S. dollar and Canadian dollar investments to the expected amount of future U.S. dollar and Canadian dollar 
obligations, respectively. Any hedging technique we implement may fail to be effective. If our hedging activities are not effective, 
changes in currency exchange rates may have a more significant impact on the market price of our common shares. 

33 

 
Risks Related to Our Business 

We, or our collaborators, may fail to successfully develop our product candidates. 

Our product candidates, which include TV-45070, GDC-0310, XEN801, along with XEN901 and other compounds in our 
preclinical and discovery pipeline, are in varying stages of development and will require substantial clinical development, testing and 
regulatory approval prior to commercialization. It may be several more years before these product candidates or any of our other 
product candidates receive marketing approval, if ever. If any of our product candidates fail to become approved products, our 
business, growth prospects, operating results and financial condition may be adversely affected and a decline of our common share 
price could result.  

We and our collaborators face substantial competition in the markets for our product candidates, which may result in others 

discovering, developing or commercializing products before us or doing so more successfully than we or our collaborators do. 

The biotechnology and pharmaceutical industries are characterized by rapidly advancing technologies, intense competition and a 

strong emphasis on proprietary products. We face potential competition in target discovery and product development from many 
different approaches and sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic 
institutions and governmental agencies and public and private research institutions. Any product candidates that we or our 
collaborators successfully develop and commercialize will compete with existing products and any new products that may become 
available in the future. 

The key competitive factors affecting the success of all of our product candidates, if approved, are likely to be their efficacy, 

safety, convenience and price; the effectiveness and safety of alternative products; the level of generic competition; and the 
availability of coverage and adequate reimbursement from government and other third-party payers. 

With respect to target discovery activities, competitors and other third parties, including academic and clinical researchers, may 

access rare families and identify novel targets for drug development before we do. 

Many of the companies against which we are competing or against which we may compete in the future have significantly 

greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting clinical trials, 
obtaining regulatory approvals and marketing approved products than we, or our collaborators, do. Mergers and acquisitions in the 
pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our 
competitors. Smaller or early stage companies may also prove to be significant competitors, particularly through collaboration 
arrangements with large and established companies. 

Our commercial opportunities could be reduced or eliminated if our competitors develop and commercialize products or 

therapies that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any 
products that we may develop. Our competitors also may obtain FDA, EMA or other regulatory approval for their products more 
rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we 
are able to enter the market. In addition, our ability to compete may be affected by decisions made by insurers or other third party 
payers. 

To the extent that we are unable to compete effectively against one or more of our competitors in these areas, our business will 

not grow and our financial condition, results of operations and common share price may suffer. 

Drug discovery and development for various pain applications is intensely competitive. There are a large number of approved 
products for neuropathic pain, inflammatory pain and other pain indications. These approved products include capsaicin, celecoxib, 
lidocaine, narcotic analgesics, gabapentin, and pregabalin. We are also aware of development programs at several pharmaceutical and 
biotechnology companies that are developing Nav1.7 inhibitors or other sodium channel inhibitors for the treatment of pain, including 
Amgen Inc., AstraZeneca PLC, Biogen Inc., Dainippon Sumitomo Co., Ltd., Eli Lilly and Company, Merck & Co., Inc., or Merck, 
NeuroQuest Inc., Vertex Pharmaceuticals Inc., Voyager Therapeutics, Inc. and Chromocell Corporation in collaboration with its 
partner Astellas Pharma Inc. Moreover, we are aware of various other product candidates in development that target other mechanisms 
of action to treat various pain indications, including calcium channel inhibitors, nerve growth factor inhibitors, and Nav1.8 inhibitors. 

34 

 
If XEN801 were approved for the treatment of acne, we anticipate it would compete with other approved prescription acne 
products including topical retinoids, oral hormonal therapies, topical and oral antimicrobials, and oral isotretinoin. In addition to 
approved prescription therapies, there are a wide range of over-the-counter, or OTC, treatments targeted at treating acne. Additionally, 
there are a number of prescription products that are used “off-label” for the treatment of acne. We are also aware of several products in 
clinical development that could potentially compete with XEN801, including products in development from Allergan PLC, AOBiome 
LLC, Braintree Laboratories Inc., Cassiopea SpA, Dermira Inc., Foamix Pharmaceuticals Ltd., Galderma SA, Mimetica Pty Ltd, 
Novan Therapeutics, Phosphagenics Ltd, Thesan Pharmaceuticals, Inc., Valeant Pharmaceuticals, and XBiotech Inc. 

We have no marketed proprietary products and have not yet advanced a product candidate beyond Phase 2 clinical trials, which 

makes it difficult to assess our ability to develop our future product candidates and commercialize any resulting products 
independently. 

We have no experience in Phase 3 and later stage clinical development, and related regulatory requirements or the 

commercialization of products. Teva Pharmaceutical Industries Ltd., or Teva, is responsible for the on-going clinical development of 
TV-45070; Genentech, a member of the Roche Group, is responsible for the on-going clinical development of GDC-0310; and 
uniQure controls and has been responsible for the development and commercialization of Glybera. Accordingly, we have not yet 
demonstrated our ability to independently and repeatedly conduct clinical development after Phase 2, obtain regulatory approval, and 
commercialize therapeutic products. We will need to develop such abilities if we are to execute on our business strategy to selectively 
develop and independently commercialize product candidates for orphan and niche indications. To execute on our business plan for 
the development of independent programs, we will need to successfully: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

execute our clinical development plans for later-stage product candidates; 

obtain required regulatory approvals in each jurisdiction in which we will seek to commercialize products; 

build and maintain appropriate sales, distribution and marketing capabilities; 

gain market acceptance for our future products, if any; and 

manage our spending as costs and expenses increase due to clinical trials, regulatory approvals and commercialization 
activities. 

If we are unsuccessful in accomplishing these objectives, we would not be able to develop and commercialize any future orphan 

and niche disease product candidates independently, and could fail to realize the potential advantages of doing so. 

If we are not successful in discovering product candidates in addition to TV-45070, GDC-0310, XEN801 and XEN901, our 

ability to expand our business and achieve our strategic objectives may be impaired. 

We use our discovery platform to identify validated drug targets and develop new product candidates. To date, our discovery 

platform has yielded one approved product, Glybera, and multiple development candidates, including TV-45070, GDC-0310, 
XEN801 and XEN901. Use of our discovery platform requires substantial technical, financial and human resources, regardless of 
whether we identify any novel drug targets. Our discovery platform may initially show promise in identifying additional potential 
product candidates, yet fail to yield viable product candidates for clinical development or commercialization. Such failure may occur 
for many reasons, including the following: any product candidate may, on further study, be shown to have serious or unexpected side 
effects or other characteristics that indicate it is unlikely to be safe or otherwise does not meet applicable regulatory criteria; and any 
product candidate may not be capable of being produced in commercial quantities at an acceptable cost, or at all. 

If we are unable to identify additional product candidates suitable for clinical development and commercialization, we may not 

be able to obtain product revenue in future periods, which likely would result in significant harm to our financial position and 
adversely impact the market price of our common shares. 

Our approach to drug discovery is unproven, and we do not know whether we will be able to develop any products of 

commercial value. 

Our discovery platform may not reproducibly or cost-effectively result in the discovery of product candidates and development 

of commercially viable products that safely and effectively treat human disease. 

There are various challenges in utilizing our discovery platform to successfully identify novel drug targets, including locating 

families suffering from rare disorders and severe phenotypes, entering into agreements with foreign collaborators, complying with 
various domestic and foreign privacy laws, accessing required technologies in a timely manner and transporting DNA across national 
borders. 

35 

 
To date, only Glybera has been both developed using our discovery platform and approved for commercial sale. If the use of our 
discovery platform fails to identify novel targets for drug discovery, or such targets prove to be unsuitable for treating human disease, 
or we are unable to develop product candidates with specificity and selectivity for such targets, we will fail to develop viable products. 
If we fail to develop and commercialize viable products, we will not achieve commercial success. 

We may encounter difficulties in managing our growth, including headcount, and expanding our operations successfully. 

Our business strategy involves continued development and, where development is successful, commercialization of select 

product candidates for orphan and niche indications independently. In order to execute on this strategy, we will need to build out a 
regulatory, sales, manufacturing, distribution and marketing infrastructure and expand our development capabilities or contract with 
third parties to provide these capabilities and infrastructure for us. To achieve this, we will need to identify, hire and integrate 
personnel who have not worked together as a group previously.  

As our operations expand, we expect that we will need to manage additional relationships with various strategic collaborators, 

suppliers and other third parties. 

Drs. Simon Pimstone and Y. Paul Goldberg each devote a small amount of their time to clinical work outside of their duties at 

our company, conducting, generally, two to three outpatient clinics per month on average. Future growth will impose significant added 
responsibilities on members of management, and our management may need to divert a disproportionate amount of its attention away 
from our day-to-day activities and devote a substantial amount of time to managing these growth activities. 

If we are unable to effectively manage our growth, our expenses may increase more than expected, our ability to generate and 

grow revenue could be reduced, and we may not be able to implement our business strategy. Our future financial performance and our 
ability to commercialize product candidates and compete effectively will depend, in part, on our ability to effectively manage any 
future growth. 

If we fail to attract and retain senior management and key personnel, we may be unable to successfully develop our product 

candidates, perform our obligations under our collaboration agreements, conduct our clinical trials and commercialize our 
product candidates. 

Our success depends in part on our continued ability to attract, retain and motivate highly qualified management, clinical and 

scientific personnel. 

We could experience difficulties attracting and retaining qualified employees as competition for qualified personnel in the 
biotechnology and pharmaceutical field is intense. We are highly dependent upon our senior management, particularly Dr. Pimstone, 
our Chief Executive Officer and President and Mr. Ian Mortimer, our Chief Financial Officer and Chief Operating Officer, as well as 
other employees. The loss of services of any of these individuals or one or more of our other members of senior management could 
materially delay or even prevent the successful development of our product candidates. 

In addition, we will need to hire additional personnel as we expand our clinical development activities and develop commercial 

capabilities, including a sales infrastructure to support our independent commercialization efforts. We may not be able to attract and 
retain personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for 
individuals with similar skill sets. The inability to recruit or loss of the services of any executive or key employee may impede the 
progress of our research, development and commercialization objectives. 

Our employees, collaborators and other personnel may engage in misconduct or other improper activities, including non-

compliance with regulatory standards and requirements and insider trading. 

We are exposed to the risk of fraud or other misconduct by our employees, collaborators, vendors, principal investigators, 
consultants and commercial partners. Misconduct by these parties could include intentional failures to comply with the regulations of 
the FDA, EMA and other non-U.S. regulators, provide accurate information to the FDA, EMA and other non-U.S. regulators, comply 
with data privacy and security and healthcare fraud and abuse laws and regulations in the U.S. and abroad, report financial information 
or data accurately or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare 
industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive 
practices. Additionally, laws regarding data privacy and security, including the federal Health Insurance Portability and Accountability 
Act of 1996, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or 
HITECH, as well as comparable laws in non-U.S. jurisdictions, may impose obligations with respect to safeguarding the privacy, use, 
security and transmission of individually identifiable health information such as genetic material or information we obtain through our 
direct-to-patient web-based recruitment approach for identifying patients with rare or extreme phenotypes. 

36 

 
Various laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales 
commission, customer incentive programs and other business arrangements. Any misconduct could also involve the improper use of 
information obtained in the course of clinical studies, which could result in regulatory sanctions and cause serious harm to our 
reputation. We have adopted a code of conduct applicable to all of our employees, but it is not always possible to identify and deter 
employee misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or 
unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to 
comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or 
asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other 
sanctions. 

Our business and operations could suffer in the event of system failures.  

Computer system, network or telecommunications failures due to events such as damage from malware, unauthorized access, 
terrorism, war, or natural disasters could interrupt our internal or partner operations. For example, the loss of preclinical trial data or 
data from completed or ongoing clinical trials for our product candidates could result in delays in our regulatory filings and 
development efforts and significantly increase our costs. To the extent that any disruption or security breach were to result in a loss of 
or damage to our data, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the 
development of our product candidates could be delayed. While we have implemented security measures and, to date, have not 
detected a cybersecurity breach nor experienced a material system failure, our internal computer systems and those of our contractors 
and consultants remain potentially vulnerable to damage from these events. 

A variety of risks associated with international operations could materially adversely affect our business. 

Our collaborator for TV-45070, Teva, is based in Israel and a significant portion of the research and development activities 
under our collaboration with Teva are performed outside of North America. Glybera has been approved for commercial sale in the EU 
by the EMA, subject to uniQure’s compliance with certain post-approval reporting and monitoring obligations. If we continue to 
engage in significant cross-border activities, we will be subject to risks related to international operations, including:

different regulatory requirements for maintaining approval of drugs and biologics in foreign countries; 

reduced protection for intellectual property rights in certain countries; 

unexpected changes in tariffs, trade barriers and regulatory requirements; 

economic weakness, including inflation, political instability or open conflict in particular foreign economies and markets; 

compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; 

foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other 
obligations of doing business in another country; 

workforce uncertainty in countries where labor unrest is more common than in North America; 

likelihood of potential or actual violations of domestic and international anti-corruption laws, such as the U.S. Foreign 
Corrupt Practices Act and the U.K. Bribery Act, or of U.S. and international export control and sanctions regulations, 
which likelihood may increase with an increase of operations in foreign jurisdictions; 

tighter restrictions on privacy and the collection and use of data, including genetic material, may apply in jurisdictions 
outside of North America, where we find some of the families with individuals that exhibit the severe phenotypes that we 
study; and 

business interruptions resulting from geopolitical actions, including war and terrorism, or natural disasters including 
earthquakes, typhoons, floods and fires. 

If any of these issues were to occur, our business could be materially harmed. 

37 

 
Our near-term operating revenue is partially dependent upon the regulatory and marketing efforts of uniQure, or its 

sublicensee, for the development and commercialization of Glybera. 

Under the terms of our license agreement with uniQure, we rely on uniQure, or its sublicensees, to market Glybera and to obtain 
and maintain regulatory approval of Glybera. In July 2013, uniQure announced that it had granted to Chiesi Farmaceutici, S.p.A., or 
Chiesi, an Italian pharmaceutical firm, an exclusive license to commercialize Glybera in the European Union, or the EU, and certain 
other countries outside of North America and Japan. Commercial sales of Glybera commenced in November 2015. Despite the efforts 
of uniQure and Chiesi, Glybera may not gain market acceptance among physicians, patients, healthcare payers and the medical 
community.  

Glybera is approved in the EU under exceptional circumstances and full approval may never be granted or the existing approval 

under exceptional circumstances could be revoked. As a condition to approval of Glybera, uniQure is required to complete a post-
approval clinical trial and is required to implement a disease registry as well as implement risk management procedures, distribute 
educational materials to healthcare professionals and patients, implement an additional manufacturing process step, comply with 
certain notification obligations and undergo annual reassessment, any negative outcome of which could potentially lead to a 
withdrawal of marketing approval for Glybera. 

Any failure of uniQure or its sublicensee to successfully commercialize Glybera or revocation of Glybera’s marketing approval in 

the EU could have an adverse effect on our near-term operating revenue and financial condition and could result in a decline in the 
price of our common shares.  

U.S. Holders of our common shares may suffer adverse tax consequences if we are characterized as a passive foreign 

investment company.  

Generally, for any taxable year in which 75% or more of our gross income is passive income, or at least 50% of the average 
quarterly value of our assets (which may be determined in part by the market value of our common shares, which is subject to change) 
are held for the production of, or produce, passive income, we would be characterized as a passive foreign investment company, or 
PFIC, for U.S. federal income tax purposes. Based on the composition of our gross income and gross assets and the nature of our 
business, we do not believe that we were a PFIC for the taxable years ended December 31, 2016, 2015 and 2014, although we could 
be a PFIC for the calendar year ending December 31, 2017 or in subsequent years. Our status as a PFIC is a fact-intensive 
determination made on an annual basis and we cannot provide any assurance regarding our PFIC status for the taxable year ending 
December 31, 2017 or for future taxable years. 

If we are a PFIC for any subsequent year, U.S. Holders of our common shares may suffer adverse tax consequences. Gains 

realized by non-corporate U.S. Holders on the sale of our common shares would be taxed as ordinary income, rather than as capital 
gain, and the preferential tax rate applicable to dividends received on our common shares would be lost. Interest charges would also be 
added to taxes on gains and dividends realized by all U.S. Holders. 

A U.S. Holder may avoid these adverse tax consequences by timely making a qualified electing fund election. For each year that 

we would meet the PFIC gross income or asset test, an electing U.S. Holder would be required to include in gross income its pro rata 
share of our net ordinary income and net capital gains, if any. A U.S. Holder may make a qualified electing fund election only if we 
commit to provide U.S. Holders with their pro rata share of our net ordinary income and net capital gains. If we are a PFIC in the 
current or a future tax year, we will provide our U.S. Holders with the information that is necessary in order for them to make a 
qualified electing fund election and to report their common shares of ordinary earnings and net capital gains for each year for which 
we are a PFIC. 

A U.S. Holder may also mitigate the adverse tax consequences if we are a PFIC by timely making a mark-to-market election. 

Generally, for each year that we would meet the PFIC gross income or asset test, an electing U.S. Holder would include in gross 
income the increase in the value of its common shares during each of its taxable years and deduct from gross income the decrease in 
the value of such shares during each of its taxable years. A mark-to-market election may be made and maintained only if our common 
shares are regularly traded on a qualified exchange, including The NASDAQ Global Market, or NASDAQ. Whether our common 
shares are regularly traded on a qualified exchange is an annual determination based on facts that, in part, are beyond our control. 
Accordingly, a U.S. Holder might not be eligible to make a mark-to-market election to mitigate the adverse tax consequences if we are 
characterized as a PFIC. 

38 

 
We may become subject to income tax in jurisdictions in which we are organized or operate, which would reduce our future 

earnings. 

There is a risk that we may become subject to income tax in jurisdictions outside of Canada and the United States, if under the 

laws of any such jurisdiction, we are considered to be carrying on a trade or business there or earn income that is considered to be 
sourced there and we do not qualify for an exemption. In jurisdictions where we do not believe we are subject to tax, we can provide 
no certainty that tax authorities in those jurisdictions will not subject one or more tax years to examination. Tax examinations are often 
complex as tax authorities may disagree with the treatment of items reported by us, the result of which could have a material adverse 
effect on our operating results and financial condition.  

Acquisitions or joint ventures could disrupt our business, cause dilution to our shareholders and otherwise harm our business. 

We actively evaluate various strategic transactions on an ongoing basis and may acquire other businesses, products or 
technologies as well as pursue strategic alliances, joint ventures or investments in complementary businesses. Any of these 
transactions could be material to our financial condition and operating results and expose us to many risks, including: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

disruption in our relationships with collaborators or suppliers as a result of such a transaction; 

unanticipated liabilities related to acquired companies; 

difficulties integrating acquired personnel, technologies and operations into our existing business; 

retention of key employees; 

diversion of management time and focus from operating our business to management of strategic alliances or joint 
ventures or acquisition integration challenges; 

increases in our expenses and reductions in our cash available for operations and other uses; and 

possible write-offs or impairment charges relating to acquired businesses. 

Foreign acquisitions involve unique risks in addition to those mentioned above, including those related to integration of 

operations across different cultures and languages, currency risks and the particular economic, political and regulatory risks associated 
with specific countries. 

Also, the anticipated benefit of any strategic alliance, joint venture or acquisition may not materialize. Future acquisitions or 

dispositions could result in potentially dilutive issuances of our equity securities, the incurrence of debt, contingent liabilities or 
amortization expenses or write-offs of goodwill, any of which could harm our financial condition. We cannot predict the number, 
timing or size of future joint ventures or acquisitions, or the effect that any such transactions might have on our operating results. 

Risks Related to Development, Clinical Testing and Regulatory Approval of Our Product Candidates 

The regulatory approval processes of the FDA, EMA and regulators in other jurisdictions are lengthy, time-consuming and 
inherently unpredictable. If we, or our collaborators, are unable to obtain timely regulatory approval for our product candidates, 
our business will be substantially harmed. 

The regulatory approval process is expensive and the time required to obtain approval from the FDA, EMA or other regulatory 

authorities in other jurisdictions to sell any product is uncertain and may take years. Whether regulatory approval will be granted is 
unpredictable and depends upon numerous factors, including the substantial discretion of the regulatory authorities. Approval policies, 
regulations, or the type and amount of preclinical and clinical data necessary to gain approval may change during the course of a 
product candidate’s clinical development and may vary among jurisdictions. Other than for Glybera in the EU, neither we nor our 
collaborators have obtained regulatory approval for any of our product candidates. It is possible that none of our existing product 
candidates or any of our future product candidates will ever obtain regulatory approval, even if we expend substantial time and 
resources seeking such approval. 

Our product candidates could fail to receive regulatory approval for many reasons, including the following: 

(cid:120) 

(cid:120) 

the FDA, EMA or other regulatory authorities may disagree with the design or implementation of our or our collaborators’ 
clinical trials; 

we or our collaborators may be unable to demonstrate to the satisfaction of the FDA, EMA or other regulatory authorities 
that a product candidate is safe and effective for its proposed indication; 

39 

 
(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

the results of clinical trials may not meet the level of statistical significance required by the FDA, EMA or other 
regulatory authorities for approval; 

we, or our collaborators, may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh its 
safety risks; 

the FDA, EMA or other regulatory authorities may disagree with our or our collaborators’ interpretation of data from 
preclinical studies or clinical trials; 

the data collected from clinical trials of our product candidates may not be sufficient to support the submission of a New 
Drug Application, or NDA, or other submission or to obtain regulatory approval in the U.S. or elsewhere; 

the FDA, EMA or other regulatory authorities may fail to approve the manufacturing processes or facilities of third-party 
manufacturers with which we or our collaborators contract for clinical and commercial supplies; and 

the approval policies or regulations of the FDA, EMA or other regulatory authorities outside of the U.S. may significantly 
change in a manner rendering our or our collaborators’ clinical data insufficient for approval. 

Even if we, or our collaborators, obtain approval for a particular product, regulatory authorities may grant approval contingent 

on the performance of costly post-approval clinical trials, or may approve a product with a label that does not include the labeling 
claims necessary or desirable for the successful commercialization of that product. 

Clinical drug development involves a lengthy and expensive process with uncertain timelines and uncertain outcomes. If 
clinical trials are prolonged or delayed, we, or our collaborators, may be unable to commercialize our product candidates on a 
timely basis. 

Clinical testing of product candidates is expensive and, depending on the stage of development, can take a substantial period of 

time to complete. Clinical trial outcomes are inherently uncertain, and failure can occur at any time during the clinical development 
process. 

Clinical trials can be halted or delayed for a variety of reasons, including those related to: 

(cid:120)

(cid:120) 

(cid:120)

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

side effects or adverse events in study participants presenting an unacceptable safety risk; 

inability to reach agreement with prospective contract research organizations, or CROs, and clinical trial sites, or the 
breach of such agreements; 

failure of third-party contractors, such as CROs, or investigators to comply with regulatory requirements; 

delay or failure in obtaining the necessary approvals from regulators or institutional review boards, or IRBs, in order to 
commence a clinical trial at a prospective trial site, or their suspension or termination of a clinical trial once commenced; 

a requirement to undertake and complete additional preclinical studies to generate data required to support the submission 
of an NDA; 

inability to enroll sufficient patients to complete a protocol, particularly in orphan diseases; 

difficulty in having patients complete a trial or return for post-treatment follow-up; 

clinical sites deviating from trial protocol or dropping out of a trial; 

problems with drug product or drug substance storage and distribution; 

adding new clinical trial sites; 

our inability to manufacture, or obtain from third parties, adequate supply of drug substance or drug product sufficient to 
complete our preclinical studies and clinical trials; and 

governmental or regulatory delays and changes in regulatory requirements, policy and guidelines. 

40 

 
The results of any Phase 3 or other pivotal clinical trial may not be adequate to support marketing approval. These clinical trials 

are lengthy and, with respect to non-orphan indications, usually involve many hundreds to thousands of patients. In addition, if the 
FDA, EMA or another applicable regulator disagrees with our or our collaborator’s choice of the key testing criterion, or primary 
endpoint, or the results for the primary endpoint are not robust or significant relative to the control group of patients not receiving the 
experimental therapy, such regulator may refuse to approve our product candidate in the region in which it has jurisdiction. The FDA, 
EMA or other applicable non-U.S. regulators also may require additional clinical trials as a condition for approving any of these 
product candidates. 

We could also encounter delays if a clinical trial is suspended or terminated by us, by our collaborators, by the IRBs of the 
institutions in which such trial is being conducted, by any Data Safety Monitoring Board for such trial, or by the FDA, EMA or other 
regulatory authorities. Such authorities may impose such a suspension or termination due to a number of factors, including failure to 
conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations 
or trial site by the FDA, EMA or other regulatory authorities resulting in the imposition of a clinical hold, product candidate 
manufacturing problems, unforeseen safety issues or adverse side effects, failure to demonstrate a benefit from using a drug, changes 
in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. In addition, delays can 
occur due to safety concerns arising from trials or other clinical data regarding another company’s product candidate in the same 
compound class as one of ours. 

If we or our collaborators experience delays in the completion of, or termination of, any clinical trial of one of our product 
candidates, the commercial prospects of the product candidate will be harmed, could shorten the patent protection period during which 
we may have the exclusive right to commercialize our products and our or our collaborators’ ability to commence product sales and 
generate product revenue from the product will be delayed. In addition, any delays in completing our clinical trials will increase our 
costs and slow down our product candidate development and approval process. Any of these occurrences may harm our business, 
financial condition and prospects significantly. In addition, many of the factors that cause, or lead to, a delay in the commencement or 
completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates. 

Our product candidates – including TV-45070 and GDC-0310 for the treatment of pain, XEN801 for the treatment of acne, and 

XEN901 for the treatment of epilepsy disorders – target novel molecular mechanisms. Regulatory authorities may require more 
extensive studies of the long-term effects of such product candidates for regulatory approval, which could delay development of our 
product candidates or our future product candidates based on novel mechanisms. 

Our clinical trials may fail to demonstrate adequately the safety and efficacy of our product candidates, which could prevent or 

delay regulatory approval and commercialization. 

Before obtaining regulatory approvals for the commercial sale of our products, we must demonstrate through lengthy, complex 

and expensive preclinical testing and clinical trials that the product candidate is both safe and effective for use in each target 
indication. Clinical trials often fail to demonstrate safety and efficacy of the product candidate studied for the target indication. Most 
product candidates that commence clinical trials are never approved as products.  

In the case of some of our product candidates, we are seeking to develop treatments for diseases for which there is relatively 

limited clinical experience, and, in some cases our clinical trials use novel end points and measurement methodologies or subjective 
patient feedback, which adds a layer of complexity to our clinical trials and may delay regulatory approval. In addition, our focus on 
orphan and niche markets may cause us to select target indications that are in more challenging therapeutic areas. For example, 
clinical trials for pain, the indication for which TV-45070 and GDC-0310 are being developed, are inherently difficult to conduct. The 
primary measure of pain is subjective patient feedback, which can be influenced by factors outside of our control, and can vary widely 
from day to day for a particular patient, and from patient to patient and site to site within a clinical study. The placebo effect also tends 
to have a more significant impact on pain trials. 

If our product candidates are not shown to be both safe and effective in clinical trials, we will not be able to obtain regulatory 

approval or commercialize these product candidates and products. In such case, we would need to develop other compounds and 
conduct associated preclinical testing and clinical trials, as well as potentially seek additional financing, all of which would have a 
material adverse effect on our business, growth prospects, operating results, financial condition and results of operations. 

41 

 
We may find it difficult to enroll patients in our clinical studies, including for orphan or niche indications, which could delay or 

prevent clinical studies of our product candidates. 

We may not be able to identify, recruit and enroll a sufficient number of patients, or those with required or desired 

characteristics to achieve diversity in a study, to complete our clinical studies in a timely manner. Patient enrollment for clinical trials 
for orphan and niche indications and for more prevalent conditions is affected by factors including: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

severity of the disease under investigation; 

design of the study protocol; 

size of the patient population; 

eligibility criteria for the study in question; 

perceived risks and benefits of the product candidate under study; 

proximity and availability of clinical study sites for prospective patients; 

availability of competing therapies and clinical studies; 

efforts to facilitate timely enrollment in clinical studies; and 

patient referral practices of physicians. 

The limited patient populations in orphan and niche indications present significant recruitment challenges for clinical trials. As 
an example of a rare childhood epilepsy disorder, the prevalence of Dravet Syndrome is estimated to be 7,500-15,000 patients in the 
U.S. It is estimated that the population of SCN8A epilepsy represents an even smaller subset amongst rare, childhood epilepsies when 
compared to Dravet Syndrome; however a full understanding of this population size is still unknown. Many of these patients may not 
be suitable or available for clinical trials. This means that we or our collaborators generally will have to run multi-site and potentially 
multi-national trials, which can be expensive and require close coordination and supervision. If we experience delays in completing 
our clinical trials, such delays could result in increased costs, delays in advancing our product development, delays in testing the 
effectiveness of our technology or termination of the clinical studies altogether. 

If we fail to obtain or maintain orphan drug designation or other regulatory exclusivity for some of our product candidates, our 

competitive position would be harmed. 

A product candidate that receives orphan drug designation can benefit from a streamlined regulatory process as well as potential 

commercial benefits following approval. Currently, this designation provides market exclusivity in the U.S. and the EU for seven 
years and ten years, respectively, if a product is the first such product approved for such orphan indication. This market exclusivity 
does not, however, pertain to indications other than those for which the drug was specifically designated in the approval, nor does it 
prevent other types of drugs from receiving orphan designations or approvals in these same indications. Further, even after an orphan 
drug is approved, the FDA can subsequently approve a drug with similar chemical structure for the same condition if the FDA 
concludes that the new drug is clinically superior to the orphan product or a market shortage occurs. 

In the EU, orphan exclusivity may be reduced to six years if the drug no longer satisfies the original designation criteria or can 

be lost altogether if the marketing authorization holder consents to a second orphan drug application or cannot supply enough drug, or 
when a second applicant demonstrates its drug is “clinically superior” to the original orphan drug. TV-45070 has received both fast 
track and orphan drug designations for the treatment of erythromelalgia, or EM, from the FDA, and flunarizine, a drug we are 
evaluating internally for the potential treatment of hemiplegic migraine, has received orphan drug designation from the FDA. If we 
seek orphan drug designations for other indications or in other jurisdictions, such as for TV-45070 in the EU, we may fail to receive 
such orphan drug designations and, even if we succeed, such orphan drug designations may fail to result in or maintain orphan drug 
exclusivity upon approval, which would harm our competitive position. 

42 

 
Results of earlier clinical trials may not be predictive of the results of later-stage clinical trials. 

The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-
stage clinical trials. Interpretation of results from early, usually smaller, studies that suggest a clinically meaningful response in some 
patients, requires caution. Results from later stages of clinical trials enrolling more patients may fail to show the desired safety and 
efficacy results or otherwise fail to be consistent with the results of earlier trials of the same product candidates. Later clinical trial 
results may not replicate earlier clinical trials for a variety of reasons, including differences in trial design, different trial endpoints (or 
lack of trial endpoints in exploratory studies), patient population, number of patients, patient selection criteria, trial duration, drug 
dosage and formulation and lack of statistical power in the earlier studies. These uncertainties are enhanced where the diseases under 
study lack established clinical endpoints and validated measures of efficacy, as is often the case with orphan diseases for which no 
drugs have been developed previously. For example, our results for two small exploratory clinical trials for primary EM pain, one 
using a topical formulation and the other an oral formulation of TV-45070, used novel measures of efficacy assessment. While these 
studies provided promising results, further larger clinical trials will be necessary to confirm and extend these observations. 

Changes in methods of product candidate manufacturing or formulation may result in additional costs or delay. 

As product candidates are developed through preclinical to late stage clinical trials towards approval and commercialization, it is 
common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way 
in an effort to optimize processes and results. Such changes carry the risk that they will not achieve these intended objectives. Any of 
these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future 
clinical trials conducted with the altered materials. This could delay completion of clinical trials, require the conduct of bridging 
clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates 
and/or jeopardize our or our collaborators’ ability to commence product sales and generate revenue. 

Even if we obtain and maintain approval for our product candidates from one jurisdiction, we may never obtain approval for 

our product candidates in other jurisdictions, which would limit our market opportunities and adversely affect our business. 

Sales of our approved products are, and will be, subject to U.S. and foreign regulatory requirements governing clinical trials and 

marketing approval, and we plan to seek regulatory approval to commercialize our product candidates in North America, the EU and 
in additional foreign countries. Clinical trials conducted in one country may not be accepted by regulatory authorities in other 
countries and regulatory approval in one country does not ensure approval in any other country, while a failure or delay in obtaining 
regulatory approval in one country may have a negative effect on the regulatory approval process in others. For example, approval in 
the U.S. by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one foreign 
regulatory authority does not ensure approval by regulatory authorities in other countries. Approval procedures vary among 
jurisdictions and can be lengthy and expensive, and involve requirements and administrative review periods different from, and 
greater than, those in the U.S., including additional preclinical studies or clinical trials. Even if our product candidates are approved, 
regulatory approval for any product may be withdrawn by the regulatory authorities in a particular jurisdiction. 

Even if a product is approved, the FDA or the EMA, as the case may be, may limit the indications for which the product may be 

marketed, require extensive warnings on the product labeling or require expensive and time-consuming clinical trials or reporting as 
conditions of approval. In many countries outside the U.S., a product candidate must be approved for reimbursement before it can be 
approved for sale in that country. In some cases, the price that we intend to charge for a product is also subject to approval. 

Regulatory authorities in countries outside of the U.S. and the EMA also have their own requirements for approval of product 

candidates with which we must comply prior to marketing in those countries. Obtaining foreign regulatory approvals and compliance 
with such foreign regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the 
introduction of our current and any future products, in certain countries. 

If we fail to receive applicable marketing approvals or comply with the regulatory requirements in international markets, our 

target market will be reduced and our ability to realize the full market potential of our product candidates will be harmed and our 
business will be adversely affected. 

We work with outside scientists and their institutions in executing our business strategy of developing product candidates using 
our discovery platform. These scientists may have other commitments or conflicts of interest, which could limit our access to their 
expertise and harm our ability to leverage our discovery platform. 

We work with scientific advisors and collaborators at academic research institutions in connection with our discovery platform. 

These scientific advisors serve as our link to the various families with extreme phenotypes in that these advisors may: 

(cid:120) 

identify families as potential candidates for study; 

43 

 
(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

obtain their consent to participate in our research; 

perform medical examinations and gather medical histories; 

conduct the initial analysis of suitability of the families to participate in our research based on the foregoing; and 

collect data and biological samples from the family members periodically in accordance with our study protocols. 

These scientists and collaborators are not our employees, rather they serve as either independent contractors or the primary 
investigators under research collaboration agreements that we have with their sponsoring academic or research institution. Such 
scientists and collaborators may have other commitments that would limit their availability to us. Although our scientific advisors 
generally agree not to do competing work, if an actual or potential conflict of interest between their work for us and their work for 
another entity arises, we may lose their services. It is also possible that some of our valuable proprietary knowledge may become 
publicly known through these scientific advisors if they breach their confidentiality agreements with us, which would cause 
competitive harm to our business. 

Risks Related to Commercialization 

If, in the future, we are unable to establish our own sales, marketing and distribution capabilities or enter into licensing or 
collaboration agreements for these purposes, we may not be successful in independently commercializing any future products. 

We do not have a sales or marketing infrastructure and, as a company, have no sales, marketing or distribution experience. Our 
strategy involves, in part, building our own commercial infrastructure to selectively commercialize future products in niche or orphan 
indications. Where we believe such involvement would advance our business, we seek to retain the right to participate in the future 
development and commercialization of such products. For example, we have a co-promotion option for TV-45070 with Teva in the 
U.S. 

To develop internal sales, distribution and marketing capabilities, we will have to invest significant amounts of financial and 

management resources, some of which will need to be committed prior to any confirmation that any of our proprietary product 
candidates will be approved. For any future products for which we decide to perform sales, marketing and distribution functions 
ourselves, we could face a number of additional risks, including: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

our inability to recruit and retain adequate numbers of effective sales and marketing personnel or develop alternative sales 
channels; 

the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe any 
future products; 

the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage 
relative to companies with more extensive product lines; and 

unforeseen costs and expenses associated with creating and maintaining an independent sales and marketing organization. 

Where and when appropriate, we may elect to utilize contract sales forces or distribution partners to assist in the 
commercialization of our product candidates. If we enter into arrangements with third parties to perform sales, marketing and 
distribution services for a product, the resulting revenue or the profitability from this revenue to us is likely to be lower than if we had 
sold, marketed and distributed that product ourselves. In addition, we may not be successful in entering into arrangements with third 
parties to sell, market, and distribute our product candidates or may be unable to do so on terms that are favorable to us. We likely will 
have little control over such third parties, and any of these third parties may fail to devote the necessary resources and attention to sell, 
market, and distribute our current or any future products effectively. 

Even if we receive regulatory approval to commercialize any of the product candidates that we develop independently, we will be 

subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. 

Any regulatory approvals that we receive for our product candidates we commercialize will be subject to limitations on the 

approved indicated uses for which the product may be marketed or subject to certain conditions of approval, and may contain 
requirements for potentially costly post-approval trials, including Phase 4 clinical trials, and surveillance to monitor the safety and 
efficacy of the marketed product. 

44 

 
For any approved product, we will need to ensure continued compliance with extensive regulations and requirements regarding 

the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and 
recordkeeping for the product. These requirements include submissions of safety and other post-approval information and reports, as 
well as continued compliance with current good manufacturing practices, or cGMP, and current good clinical practices, or cGCP, for 
any clinical trials that we or our collaborators conduct post-approval. Later discovery of previously unknown problems with a product, 
including adverse events of unanticipated severity or frequency, or with third-party manufacturers or manufacturing processes, or 
failure to comply with regulatory requirements, may result in, among other things: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market or voluntary or 
mandatory product recalls; 

fines, warning letters or holds on any post-approval clinical trials; 

refusal by the FDA, EMA or another applicable regulatory authority to approve pending applications or supplements to 
approved applications filed by us or our collaborators, or suspension or revocation of product license approvals; 

product seizure or detention, or refusal to permit the import or export of products; and 

injunctions or the imposition of civil or criminal penalties. 

Occurrence of any of the foregoing could have a material and adverse effect on our business and results of operations. 

If the market opportunities for any product that we or our collaborators develop are smaller than we believe they are, our 

revenue may be adversely affected and our business may suffer. 

We intend to focus our independent product development on treatments for rare diseases. Our projections of both the number of 

people who have these diseases, as well as the subset of people with these diseases who have the potential to benefit from treatment 
with our product candidates, are based on estimates. Currently, most reported estimates of the prevalence of these diseases are based 
on studies of small subsets of the population in specific geographic areas, which are then extrapolated to estimate the prevalence of the 
diseases in the U.S. or elsewhere. If the prevalence of such diseases is smaller than we have projected, then, even if our products are 
approved, we may not be able to successfully commercialize them. 

Even if we or our collaborators receive approval to commercialize our products, unfavorable pricing regulations and 

challenging third-party coverage and reimbursement practices could harm our business. 

Our or any collaborators’ ability to commercialize any products successfully will depend, in part, on the extent to which 
coverage and reimbursement for these products and related treatments will be available from government healthcare programs, private 
health insurers, managed care plans, and other organizations. Government authorities and third-party payers, such as private health 
insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. A 
primary trend in the U.S. healthcare industry is cost containment. Government authorities and third-party payers have attempted to 
control costs by limiting coverage and the amount of reimbursement for particular medications. Increasingly, third-party payers are 
requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for 
medical products. We cannot be sure that coverage and reimbursement will be available for any product that we or any collaborator 
commercialize and, if reimbursement is available, the level of reimbursement. In addition, coverage and reimbursement may impact 
the demand for, or the price of, any product candidate for which we or a collaborator obtains marketing approval. If coverage and 
reimbursement are not available or reimbursement is available only to limited levels, we or our collaborators may not be able to 
successfully commercialize any product candidate for which marketing approval is obtained. 

There may be significant delays in obtaining coverage and reimbursement for newly approved drugs, and coverage may be more 

limited than the purposes for which the drug is approved by the FDA, EMA or other regulatory authorities. Moreover, eligibility for 
coverage and reimbursement does not imply that a drug will be paid for in all cases or at a rate that covers our costs, including 
research, development, manufacture, sale and distribution expenses. Interim reimbursement levels for new drugs, if applicable, may 
also be insufficient to cover our and any collaborator’s costs and may not be made permanent. Reimbursement rates may vary 
according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower 
cost drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory 
discounts or rebates required by government healthcare programs or private payers and by any future relaxation of laws that presently 
restrict imports of drugs from countries where they may be sold at lower prices than in the U.S. Third-party payers often rely upon 
Medicare coverage policy and payment limitations in setting their own reimbursement policies. Our or any collaborator’s inability to 
promptly obtain coverage and profitable payment rates from both government-funded and private payers for any approved products 
that we or our collaborators develop could have a material adverse effect on our operating results, our ability to raise capital needed to 
commercialize products and our overall financial condition. 

45 

 
Our target patient populations in orphan and niche indications, where we intend to selectively develop and commercialize 

products independently, are relatively small. In order for therapies that are designed to treat smaller patient populations to be 
commercially viable, the reimbursement for such therapies needs to be higher, on a relative basis, to account for the lack of volume. 
Accordingly, we will need to implement a coverage and reimbursement strategy for any approved product that accounts for the 
smaller potential market size. If we are unable to establish or sustain coverage and adequate reimbursement for our current and any 
future products from third party payers or the government, the adoption of those products and sales revenue will be adversely affected, 
which, in turn, could adversely affect the ability to market or sell those products. 

Recently enacted and future legislation may increase the difficulty and cost for us to commercialize any products that we or our 

collaborators develop and affect the prices we may obtain. 

The U.S. and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to 

change the healthcare system in ways that could affect our ability to sell any of our products profitably, once such products are 
approved for sale. Among policy makers and payers in the U.S. and elsewhere, there is significant interest in promoting changes in 
healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the U.S., the 
pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. 

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, 
collectively, PPACA, was enacted in 2010 and includes measures that have significantly changed, or will significantly change, the 
way healthcare is financed by both governmental and private insurers. Among the provisions of PPACA of importance to the 
pharmaceutical industry are the following: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs and biologic 
agents, apportioned among these entities according to their market share in certain government healthcare programs, that 
began in 2011; 

an increase in the rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23% and 13% of the 
average manufacturer price for branded and generic drugs, respectively; 

a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point-of-sale 
discounts to negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a 
condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; 

extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in 
Medicaid managed care organizations; 

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage 
to additional individuals and by adding new mandatory eligibility categories for certain individuals with income at or 
below 133% of the Federal Poverty Level beginning in 2014, thereby potentially increasing manufacturers’ Medicaid 
rebate liability; 

expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program; 

new requirements under the federal Open Payments program, created under Section 6002 of the PPACA and its 
implementing regulations that manufacturers of drugs, devices, biologics and medical supplies for which payment is 
available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) report annually 
to the U.S. Department of Health and Human Services, or HHS, information related to “payments or other transfers of 
value” made or distributed to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) 
and teaching hospitals and that applicable manufacturers and applicable group purchasing organizations report annually to 
the HHS ownership and investment interests held by physicians (as defined above) and their immediate family members, 
with data collection required beginning August 1, 2013 and reporting to the Centers for Medicare & Medicaid Services, or 
CMS, required by the 90th day of each subsequent calendar year, and disclosure of such information made on a publicly 
available website starting September 2014; 

a requirement to annually report drug samples that manufacturers and distributors provide to physicians; 

expansion of healthcare fraud and abuse laws, including the False Claims Act and the Anti-Kickback Statute, new 
government investigative powers, and enhanced penalties for noncompliance; 

a licensure framework for follow-on biologic products; 

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical 
effectiveness research, along with funding for such research; 

46 

 
(cid:120) 

(cid:120) 

creation of the Independent Payment Advisory Board which, beginning in 2014, has authority to recommend certain 
changes to the Medicare program that could result in reduced payments for prescription drugs and those recommendations 
could have the effect of law even if Congress does not act on the recommendations; and 

establishment of a Center for Medicare Innovation at CMS to test innovative payment and service delivery models to 
lower Medicare and Medicaid spending, potentially including prescription drug spending, that began, in 2011. 

In the EU, similar political, economic and regulatory developments may affect our ability to profitably commercialize our 
current or any future products. In addition to continuing pressure on prices and cost containment measures, legislative developments at 
the EU or member state level may result in significant additional requirements or obstacles that may increase our operating costs. In 
international markets, reimbursement and healthcare payment systems vary significantly by country, and many countries have 
instituted price ceilings on specific products and therapies. Glybera and our future products, if any, might not be considered medically 
reasonable and necessary for a specific indication or cost-effective by third-party payers. An adequate level of reimbursement might 
not be available for such products and third-party payers’ reimbursement policies might adversely affect our or our collaborators’ 
ability to sell Glybera and any future products profitably.  

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional 

activities for pharmaceutical products. We cannot be sure whether additional legislative changes will be enacted, or whether the FDA 
regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our product 
candidates, if any, may be. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may significantly delay 
or prevent marketing approval, as well as subject us to more stringent product labeling and post-approval testing and other 
requirements. 

The Trump administration and Congress are also expected to attempt broad sweeping changes to the current health care laws, 

including PPACA. The impact of those changes on us and the pharmaceutical industry as a whole is currently unknown. Any changes 
to the PPACA are likely to have an impact on our results of operations, and may have a material adverse effect on our result of 
operations. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or 
administrative action, either in the U.S. or abroad. If we or our collaborators are slow or unable to adapt to changes in existing 
requirements or the adoption of new requirements or policies, or if we or our collaborators are not able to maintain regulatory 
compliance, our product candidates may lose any marketing approval that may have been obtained and we may not achieve or sustain 
profitability, which would adversely affect our business. 

Foreign governments tend to impose strict price controls, which may adversely affect our future profitability. 

In most foreign countries, particularly those in the EU, prescription drug pricing and/or reimbursement is subject to 
governmental control. In those countries that impose price controls, pricing negotiations with governmental authorities can take 
considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some 
countries, we or our collaborators may be required to conduct a clinical trial that compares the cost-effectiveness of our product 
candidate to other available therapies. 

Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing review 

period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing 
remains subject to continuing governmental control even after initial approval is granted. As a result, we or our collaborators might 
obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay commercial launch 
of the product, possibly for lengthy time periods, and negatively impact the revenue that are generated from the sale of the product in 
that country. If reimbursement of such products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory 
levels, or if there is competition from lower priced cross-border sales, our profitability will be negatively affected. 

47 

 
Risks Related to Our Dependence on Third Parties 

We depend on our collaborative relationship with Teva to further develop and commercialize TV-45070, and if our relationship 

is not successful or is terminated, we may not be able to effectively develop and/or commercialize TV-45070, which would have a 
material adverse effect on our business. 

We depend on Teva to collaborate with us to develop and globally commercialize TV-45070. Under the agreement, Teva 

controls all decision-making with respect to the clinical development and commercialization for TV-45070.  

As a result of our dependence on Teva, the eventual success or commercial viability of TV-45070 is largely beyond our control. 

The financial returns to us, if any, depend in large part on the achievement of development and commercialization milestones, plus a 
share of any revenue from sales. Therefore, our success, and any associated financial returns to us and our investors, will depend in 
large part on Teva’s performance under the agreement. We are subject to a number of additional specific risks associated with our 
dependence on our collaborative relationship with Teva, including: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

adverse decisions by Teva or the Joint Development Committee regarding the development and commercialization of TV-
45070; 

possible disagreements as to the timing, nature and extent of our development plans, including clinical trials or regulatory 
approval strategy; 

loss of significant rights if we fail to meet our obligations under the agreement; 

our limited control over clinical trials of TV-45070; 

changes in key management personnel at Teva, including in members of the Joint Development Committee; and 

possible disagreements with Teva regarding the agreement, for example, with regard to ownership of intellectual property 
rights. 

If either we or Teva fail to perform our respective obligations, any clinical trial, regulatory approval or development progress 
could be significantly delayed or halted, could result in costly or time-consuming litigation or arbitration and could have a material 
adverse effect on our business. 

Decisions by Teva to emphasize other drug candidates currently in its portfolio ahead of our product candidates, or to add 
competitive agents to its portfolio could result in a decision to terminate the agreement, in which event, among other things, we may 
be responsible for paying any remaining costs of all ongoing or future clinical trials. 

In addition, Teva’s executive offices and a substantial percentage of their manufacturing capabilities are located in Israel. Teva’s 

Israeli operations are dependent upon materials imported from outside Israel, and Teva also exports significant amounts of products 
from Israel. Accordingly, our collaboration with Teva could be materially and adversely affected by acts of terrorism or if major 
hostilities were to occur in the Middle East or trade between Israel and its present trading partners were curtailed, including as a result 
of acts of terrorism in the U.S. or elsewhere. 

Any of the above discussed scenarios could adversely affect the timing and extent of our development and commercialization 

activities, which could cause significant delays and funding shortfalls for those activities and seriously harm our business. 

Our prospects for successful development and commercialization of our partnered products and product candidates are 

dependent upon the research, development and marketing efforts of our collaborators. 

We have no control over the resources, time and effort that our collaborators may devote to our programs and limited access to 

information regarding or resulting from such programs. We are dependent on Teva, Genentech, and Merck to fund and conduct the 
research and any clinical development of product candidates under our collaboration with each of them, and for the successful 
regulatory approval, marketing and commercialization of one or more of such products or product candidates and on uniQure, and its 
licensee Chiesi to successfully commercialize Glybera. Such success will be subject to significant uncertainty. 

Our ability to recognize revenue from successful collaborations may be impaired by multiple factors including: 

(cid:120) 

(cid:120) 

a collaborator may shift its priorities and resources away from our programs due to a change in business strategies, or a 
merger, acquisition, sale or downsizing of its company or business unit; 

a collaborator may cease development in therapeutic areas which are the subject of our strategic alliances; 

48 

 
(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

a collaborator may change the success criteria for a particular program or product candidate thereby delaying or ceasing 
development of such program or candidate; 

a significant delay in initiation of certain development activities by a collaborator will also delay payment of milestones 
tied to such activities, thereby impacting our ability to fund our own activities; 

a collaborator could develop a product that competes, either directly or indirectly, with our current or future products, if 
any; 

a collaborator with commercialization obligations may not commit sufficient financial or human resources to the 
marketing, distribution or sale of a product; 

a collaborator with manufacturing responsibilities may encounter regulatory, resource or quality issues and be unable to 
meet demand requirements; 

a collaborator may exercise its rights under the agreement to terminate our collaboration; 

a dispute may arise between us and a collaborator concerning the research or development of a product candidate, 
commercialization of a product or payment of royalties or milestone payments, any of which could result in a delay in 
milestones, royalty payments or termination of a program and possibly resulting in costly litigation or arbitration which 
may divert management attention and resources; 

a collaborator may not adequately protect the intellectual property rights associated with a product or product candidate; 
and 

a collaborator may use our proprietary information or intellectual property in such a way as to invite litigation from a third 
party. 

If our collaborators do not perform in the manner we expect or fulfill their responsibilities in a timely manner, or at all, the 

clinical development, regulatory approval and commercialization efforts could be delayed, terminated or be commercially 
unsuccessful. Conflicts between us and our collaborators may arise. In the event of termination of one or more of our collaboration 
agreements, it may become necessary for us to assume the responsibility of any terminated product or product candidates at our own 
expense or seek new collaborators. In that event, we would likely be required to limit the size and scope of one or more of our 
independent programs or increase our expenditures and seek additional funding which may not be available on acceptable terms or at 
all, and our business would be materially and adversely affected. 

We may not be successful in establishing new collaborations or maintaining our existing alliances, which could adversely affect 

our ability to develop future product candidates and commercialize future products. 

We may seek to enter into additional product collaborations in the future, including alliances with other biotechnology or 
pharmaceutical companies, to enhance and accelerate the development of our future product candidates and the commercialization of 
any resulting products. We face significant competition in seeking appropriate collaborators and the negotiation process is time-
consuming and complex. Moreover, we may not be successful in our efforts to establish other collaborations or other alternative 
arrangements for any future product candidates because our research and development pipeline may be insufficient, our product 
candidates may be deemed to be at too early of a stage of development for collaboration effort and/or third parties may view our 
product candidates as lacking the requisite potential to demonstrate safety and efficacy. Even if we are successful in our efforts to 
establish collaborations, the terms that we agree upon may not be favorable to us and we may not be able to maintain such 
collaborations if, for example, development or approval of a product candidate is delayed or sales of an approved product are 
disappointing. 

If any of our existing collaboration agreements is terminated, or if we determine that entering into other product collaborations 

is in our best interest but we either fail to enter into, delay in entering into or fail to maintain such collaborations: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

the development of certain of our current or future product candidates may be terminated or delayed; 

our cash expenditures related to development of our product candidates would increase significantly and we may need to 
seek additional financing sooner than expected; 

we may be required to hire additional employees or otherwise develop expertise, such as clinical, regulatory, sales and 
marketing expertise, which we do not currently have; 

we will bear all of the risk related to the development of any such product candidates; and 

the competitiveness of any product that is commercialized could be reduced. 

49 

 
We intend to rely on third-party manufacturers to produce our clinical product candidate supplies. Any failure by a third-party 

manufacturer to produce acceptable supplies for us may delay or impair our ability to initiate or complete our clinical trials or 
commercialize approved products. 

We do not currently own or operate any manufacturing facilities nor do we have any in-house manufacturing experience or 
personnel. We rely on our collaborators to manufacture product candidates licensed to them or work with multiple third party contract 
manufacturers to produce sufficient quantities of materials required for the manufacture of our product candidates for preclinical 
testing and clinical trials and intend to do so for the commercial manufacture of our products. If we are unable to arrange for such 
third-party manufacturing sources, or fail to do so on commercially reasonable terms, we may not be able to successfully produce 
sufficient supply of product candidate or we may be delayed in doing so. Such failure or substantial delay could materially harm our 
business. 

Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured product candidates 

ourselves, including reliance on the third party for regulatory compliance and quality control and assurance, volume production, the 
possibility of breach of the manufacturing agreement by the third party because of factors beyond our control (including a failure to 
synthesize and manufacture our product candidates in accordance with our product specifications) and the possibility of termination or 
nonrenewal of the agreement by the third party at a time that is costly or damaging to us. In addition, the FDA, EMA and other 
regulatory authorities require that our product candidates be manufactured according to cGMP and similar foreign standards. 
Pharmaceutical manufacturers and their subcontractors are required to register their facilities and/or products manufactured at the time 
of submission of the marketing application and then annually thereafter with the FDA and certain state and foreign agencies. They are 
also subject to periodic unannounced inspections by the FDA, state and other foreign authorities. Any subsequent discovery of 
problems with a product, or a manufacturing or laboratory facility used by us or our collaborators, may result in restrictions on the 
product or on the manufacturing or laboratory facility, including marketed product recall, suspension of manufacturing, product 
seizure, or a voluntary withdrawal of the drug from the market. Any failure by our third-party manufacturers to comply with cGMP or 
failure to scale up manufacturing processes, including any failure to deliver sufficient quantities of product candidates in a timely 
manner, could lead to a delay in, or failure to obtain, regulatory approval of any of our product candidates. 

We rely on third parties to monitor, support, conduct and/or oversee clinical trials of the product candidates that we are 
developing independently and, in some cases, to maintain regulatory files for those product candidates. We may not be able to 
obtain regulatory approval for our product candidates or commercialize any products that may result from our development 
efforts, if we are not able to maintain or secure agreements with such third parties on acceptable terms, if these third parties do not 
perform their services as required, or if these third parties fail to timely transfer any regulatory information held by them to us. 

We rely on entities outside of our control, which may include academic institutions, CROs, hospitals, clinics and other third-

party collaborators, to monitor, support, conduct and/or oversee preclinical and clinical studies of our current and future product 
candidates. We also rely on third parties to perform clinical trials on our current and future product candidates when they reach that 
stage. As a result, we have less control over the timing and cost of these studies and the ability to recruit trial subjects than if we 
conducted these trials with our own personnel. 

If we are unable to maintain or enter into agreements with these third parties on acceptable terms, or if any such engagement is 

terminated prematurely, we may be unable to enroll patients on a timely basis or otherwise conduct our trials in the manner we 
anticipate. In addition, there is no guarantee that these third parties will devote adequate time and resources to our studies or perform 
as required by our contract or in accordance with regulatory requirements, including maintenance of clinical trial information 
regarding our product candidates. If these third parties fail to meet expected deadlines, fail to transfer to us any regulatory information 
in a timely manner, fail to adhere to protocols or fail to act in accordance with regulatory requirements or our agreements with them, 
or if they otherwise perform in a substandard manner or in a way that compromises the quality or accuracy of their activities or the 
data they obtain, then clinical trials of our future product candidates may be extended or delayed with additional costs incurred, or our 
data may be rejected by the FDA, EMA or other regulatory agencies. 

Ultimately, we are responsible for ensuring that each of our clinical trials is conducted in accordance with the applicable 

protocol, legal, regulatory and scientific standards, and our reliance on third parties does not relieve us of our regulatory 
responsibilities. 

50 

 
We and our CROs are required to comply with cGCP regulations and guidelines enforced by the FDA, the competent authorities 

of the member states of the European Economic Area and comparable foreign regulatory authorities for products in clinical 
development. Regulatory authorities enforce these cGCP regulations through periodic inspections of clinical trial sponsors, principal 
investigators and clinical trial sites. For example, one of the sites that participated in our XEN801 Phase 2 clinical acne trial was 
recently the subject of a routine inspection by Health Canada, which is still currently in progress. The initial inspection deficiencies 
that were identified are related to the sponsor obligations around good clinical practices and records. We expect to receive a written 
report from Health Canada with more detail in the coming weeks, and we will have an opportunity to respond with proposed 
corrective actions, if necessary. Given the nature of these deficiencies, we do not believe that any of the findings have an impact on 
the integrity of the data, safety of the trial subjects or the overall validity of the trial. If we or any of our CROs fail to comply with 
applicable cGCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and our submission of 
marketing applications may be delayed or the FDA may require us to perform additional clinical trials before approving our marketing 
applications. Upon inspection, the FDA could determine that any of our clinical trials fail or have failed to comply with applicable 
cGCP regulations. In addition, our clinical trials must be conducted with product produced under the cGMP regulations enforced by 
the FDA, and our clinical trials may require a large number of test subjects. Our failure to comply with these regulations may require 
us to repeat clinical trials, which would delay the regulatory approval process and increase our costs. Moreover, our business may be 
implicated if any of our CROs violates federal or state fraud and abuse or false claims laws and regulations or healthcare privacy and 
security laws. 

If any of our clinical trial sites terminates for any reason, we may experience the loss of follow-up information on patients 

enrolled in our ongoing clinical trials unless we are able to transfer the care of those patients to another qualified clinical trial site. 
Further, if our relationship with any of our CROs is terminated, we may be unable to enter into arrangements with alternative CROs 
on commercially reasonable terms, or at all. 

Switching or adding CROs or other suppliers can involve substantial cost and require extensive management time and focus. In 
addition, there is a natural transition period when a new CRO or supplier commences work. As a result, delays may occur, which can 
materially impact our ability to meet our desired clinical development timelines. If we are required to seek alternative supply 
arrangements, the resulting delays and potential inability to find a suitable replacement could materially and adversely impact our 
business. 

Risks Related to Intellectual Property 

We could be unsuccessful in obtaining or maintaining adequate patent protection for one or more of our products or product 

candidates. 

Our commercial success will depend, in large part, on our ability to obtain and maintain patent and other intellectual property 
protection with respect to our product candidates. Patents might not be issued or granted with respect to our patent applications that 
are currently pending, and issued or granted patents might later be found to be invalid or unenforceable, be interpreted in a manner 
that does not adequately protect our current product or any future products, or fail to otherwise provide us with any competitive 
advantage. The patent position of biotechnology and pharmaceutical companies is generally uncertain because it involves complex 
legal and factual considerations. The standards applied by the U.S. Patent and Trademark Office, or USPTO, and foreign patent 
offices in granting patents are not always applied uniformly or predictably. For example, there is no uniform worldwide policy 
regarding patentable subject matter or the scope of claims allowable in biotechnology and pharmaceutical patents. Consequently, 
patents may not issue from our pending patent applications. As such, we do not know the degree of future protection that we will have 
on our proprietary products and technology, if any, and a failure to obtain adequate intellectual property protection with respect to our 
product candidates and proprietary technology could have a material adverse impact on our business. 

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and/or applications will be 

due to be paid to the USPTO and various governmental patent agencies outside of the U.S. in several stages over the lifetime of the 
patents and/or applications. The USPTO and various non-US governmental patent agencies require compliance with a number of 
procedural, documentary, fee payment and other similar provisions during the patent application process. We employ reputable law 
firms and other professionals to help us comply with respect to the patents and patent applications that we own, and we rely upon our 
licensors or our other collaborators to effect compliance with respect to the patents and patent applications that we license. In many 
cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the applicable rules. However, 
there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial 
or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors might be able to enter the market and 
this circumstance would have a material adverse effect on our business. 

51 

 
Our intellectual property rights will not necessarily provide us with competitive advantages. 

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have 

limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage.  

The following examples are illustrative:

others may be able to make compounds that are similar to our product candidates but that are not covered by the claims of 
the patents that we or our collaborators own or have exclusively licensed; 

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

issued patents that we own or have exclusively licensed may not provide us with any competitive advantages, or may be 
held invalid or unenforceable, as a result of legal challenges by our competitors; 

we may obtain patents for certain compounds many years before we obtain marketing approval for products containing 
such compounds, and because patents have a limited life, which may begin to run prior to the commercial sale of the 
related product, the commercial value of our patents may be limited; 

our competitors might conduct research and development activities in countries where we do not have patent rights and 
then use the information learned from such activities to develop competitive products for sale in our major commercial 
markets; 

we may fail to develop additional proprietary technologies that are patentable; 

the laws of certain foreign countries may not protect our intellectual property rights to the same extent as the laws of the 
U.S., or we may fail to apply for or obtain adequate intellectual property protection in all the jurisdictions in which we 
operate; and 

the patents of others may have an adverse effect on our business, for example by preventing us from marketing one or 
more of our product candidates for one or more indications. 

Any of the aforementioned threats to our competitive advantage could have a material adverse effect on our business. 

We may not be able to protect our intellectual property rights throughout the world. 

Filing, prosecuting and defending patents on product candidates in all countries throughout the world would be prohibitively 

expensive, and our intellectual property rights in some countries outside the U.S. can be less extensive than those in the U.S. In 
addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in 
the U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the U.S., or 
from selling or importing products made using our inventions in and into the U.S. or other jurisdictions. Competitors may use our 
technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export 
otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as that in the U.S. These 
products may compete with our current or future products, if any, and our patents or other intellectual property rights may not be 
effective or sufficient to prevent them from competing. 

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign 
jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, 
trade secrets and other intellectual property protection, particularly those relating to biotechnology products, which could make it 
difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights 
generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and 
attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent 
applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that 
we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to 
enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the 
intellectual property that we develop or license. 

52 

 
Our patents covering one or more of our products or product candidates could be found invalid or unenforceable if challenged. 

Any of our intellectual property rights could be challenged or invalidated despite measures we take to obtain patent and other 

intellectual property protection with respect to our product candidates and proprietary technology. For example, if we were to initiate 
legal proceedings against a third party to enforce a patent covering one of our product candidates, the defendant could counterclaim 
that our patent is invalid and/or unenforceable. In patent litigation in the U.S. and in some other jurisdictions, defendant counterclaims 
alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any 
of several statutory requirements, for example, lack of novelty, obviousness or non-enablement. Grounds for an unenforceability 
assertion could be an allegation that someone connected with prosecution of the patent withheld material information from the USPTO 
or the applicable foreign counterpart, or made a misleading statement, during prosecution. A litigant or the USPTO itself could 
challenge our patents on this basis even if we believe that we have conducted our patent prosecution in accordance with the duty of 
candor and in good faith. The outcome following such a challenge is unpredictable. 

With respect to challenges to the validity of our patents, for example, there might be invalidating prior art, of which we and the 

patent examiner were unaware during prosecution. If a defendant were to prevail on a legal assertion of invalidity and/or 
unenforceability, we would lose at least part, and perhaps all, of the patent protection on a product candidate. Even if a defendant does 
not prevail on a legal assertion of invalidity and/or unenforceability, our patent claims may be construed in a manner that would limit 
our ability to enforce such claims against the defendant and others. The cost of defending such a challenge, particularly in a foreign 
jurisdiction, and any resulting loss of patent protection could have a material adverse impact on one or more of our product candidates 
and our business. 

Enforcing our intellectual property rights against third parties may also cause such third parties to file other counterclaims 

against us, which could be costly to defend, particularly in a foreign jurisdiction, and could require us to pay substantial damages, 
cease the sale of certain products or enter into a license agreement and pay royalties (which may not be possible on commercially 
reasonable terms or at all). Any efforts to enforce our intellectual property rights are also likely to be costly and may divert the efforts 
of our scientific and management personnel. 

Patent protection and patent prosecution for some of our product candidates is dependent on, and the ability to assert patents 

and defend them against claims of invalidity is maintained by, third parties. 

There have been and may be times in the future when certain patents that relate to our product candidates or any approved 
products are controlled by our licensees or licensors. Although we may, under such arrangements, have rights to consult with our 
collaborators on actions taken as well as back-up rights of prosecution and enforcement, we have in the past and may in the future 
relinquish rights to prosecute and maintain patents and patent applications within our portfolio as well as the ability to assert such 
patents against infringers. Currently, some of these rights relating to the patent portfolios for TV-45070, GDC-0310, Glybera and 
some of our earlier stage product candidates are held by our collaborators. 

If any current or future licensee or licensor with rights to prosecute, assert or defend patents related to our product candidates 

fails to appropriately prosecute and maintain patent protection for patents covering any of our product candidates, or if patents 
covering any of our product candidates are asserted against infringers or defended against claims of invalidity or unenforceability in a 
manner which adversely affects such coverage, our ability to develop and commercialize any such product candidate may be adversely 
affected and we may not be able to prevent competitors from making, using and selling competing products. 

We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time 

consuming and unsuccessful. 

Competitors may infringe our patents or the patents of our licensors. To counter infringement or unauthorized use, we may be 

required to file infringement claims, which can be expensive and time-consuming. In addition, in an infringement proceeding, a court 
may decide that a patent of ours or one of our licensors is not valid or is unenforceable, or may refuse to stop the other party in such 
infringement proceeding from using the technology at issue on the grounds that our patents do not cover the technology in question. 
An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated, held 
unenforceable or interpreted narrowly, and could put any of our patent applications at risk of not yielding an issued patent. 

53 

 
Interference proceedings, derivation proceedings, entitlement proceedings, ex parte reexamination, inter partes reexamination, 
inter partes review, post-grant review, and opposition proceedings provoked by third parties or brought by the USPTO or any foreign 
patent authority may be used to challenge inventorship, ownership, claim scope, or validity of our patent applications. An unfavorable 
outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our 
business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms, if any license is offered 
at all. Litigation or interference proceedings may fail and, even if successful, may result in substantial costs and distract our 
management and other employees. 

We may not be able to prevent, alone or with our licensors, misappropriation of our trade secrets or confidential information, 
particularly in countries where the laws may not protect those rights as fully as in the U.S. Furthermore, because of the substantial 
amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential 
information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the 
results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to 
be negative, it could have a substantial adverse effect on the price of our common shares. 

Claims that our product candidates or the sale or use of our future products infringe the patent or other intellectual property 
rights of third parties could result in costly litigation or could require substantial time and money to resolve, even if litigation is 
avoided. 

Our commercial success depends upon our ability to develop product candidates and commercialize products that may be 
approved in the future, using our proprietary technology without infringing the intellectual property rights of others. Our product or 
product candidates or any uses of them may now and in the future infringe third-party patents or other intellectual property rights. 
Third parties might allege that we or our collaborators are infringing their patent rights or that we have misappropriated their trade 
secrets, or that we are otherwise violating their intellectual property rights, whether with respect to the manner in which we have 
conducted our research or to the composition, use or manufacture of the compounds we have developed or are developing with our 
collaborators. Such third parties might resort to litigation against us or other parties we have agreed to indemnify, which litigation 
could be based on either existing intellectual property or intellectual property that arises in the future. 

It is possible that relevant patents or patent applications held by third parties will cover our product candidates at the time of 

launch and we may also fail to identify, relevant patents or patent applications held by third parties that cover our product candidates. 
For example, applications filed before November 29, 2000, and certain applications filed after that date that will not be filed outside 
the U.S. remain confidential until patents issue. Other patent applications in the U.S. and several other jurisdictions are published 
approximately 18 months after the earliest filing for which priority is claimed, with such earliest filing date being commonly referred 
to as the priority date. Furthermore, publication of discoveries in the scientific or patent literature often lags behind actual discoveries. 
Therefore, we cannot be certain that we or our collaborators were the first to invent, or the first to file patent applications on, our 
product candidates or for their uses, or that our product candidates will not infringe patents that are currently issued or that are issued 
in the future. In the event that a third party has also filed a patent application covering one of our product candidates or a similar 
invention, we may have to participate in an adversarial proceeding, known as an interference, declared by the USPTO or its foreign 
counterpart to determine priority of invention. Additionally, pending patent applications and patents which have been published can, 
subject to certain limitations, be later amended in a manner that could cover our current or future products, if any, or their use. 

Defending against claims of patent infringement, misappropriation of trade secrets or other violations of intellectual property 
rights could be costly and time consuming, regardless of the outcome. Thus, even if we were to ultimately prevail, or to settle at an 
early stage, such litigation could burden us with substantial unanticipated costs. In addition, litigation or threatened litigation could 
result in significant demands on the time and attention of our management team, distracting them from the pursuit of other company 
business. Claims that our product candidates or the sale or use of our future products infringe, misappropriate or otherwise violate 
third-party intellectual property rights could therefore have a material adverse impact on our business. 

Most of our competitors are larger than we are and have substantially greater financial resources. They are, therefore, likely to 
be able to sustain the costs of complex intellectual property litigation longer than we could. In addition, the uncertainties associated 
with litigation could have a material adverse effect on our ability to raise the funds necessary to conduct our clinical trials, continue 
our internal research programs, in-license needed technology, or enter into strategic collaborations that would help us bring our 
product candidates to market. 

In addition, any future intellectual property litigation, interference or other administrative proceedings will result in additional 
expense and distraction of our personnel. An adverse outcome in such litigation or proceedings may expose us or any future strategic 
collaborators to loss of our proprietary position, expose us to significant liabilities, or require us to seek licenses that may not be 
available on commercially acceptable terms, if at all, each of which could have a material adverse effect on our business. 

54 

 
Unfavorable outcomes in intellectual property litigation could limit our research and development activities and/or our ability to 

commercialize certain products. 

If third parties successfully assert their intellectual property rights against us, we might be barred from using certain aspects of 
our technology, or barred from developing and commercializing certain products. Prohibitions against using certain technologies, or 
prohibitions against commercializing certain products, could be imposed by a court or by a settlement agreement between us and a 
plaintiff. In addition, if we are unsuccessful in defending against allegations that we have infringed, misappropriated or otherwise 
violated patent or other intellectual property rights of others, we may be forced to pay substantial damage awards to the plaintiff. 
There is inevitable uncertainty in intellectual property litigation and we could lose, even if the case against us is weak or flawed. If 
litigation leads to an outcome unfavorable to us, we may be required to obtain a license from the intellectual property owner in order 
to continue our research and development programs or to market any resulting product. It is possible that the necessary license will not 
be available to us on commercially acceptable terms, or at all. Alternatively, we may be required to modify or redesign our current or 
future products, if any, in order to avoid infringing or otherwise violating third-party intellectual property rights. This may not be 
technically or commercially feasible, may render those products less competitive, or may delay or prevent the entry of those products 
to the market. Any of the foregoing could limit our research and development activities, our ability to commercialize one or more 
product candidates, or both. 

In order to avoid or settle potential claims with respect to any patent or other intellectual property rights of third parties, we may 

choose or be required to seek a license from a third party and be required to pay license fees or royalties or both, which could be 
substantial. These licenses may not be available on acceptable terms, or at all. Even if we or any future collaborators were able to 
obtain a license, the rights may be nonexclusive, which could result in our competitors gaining access to the same intellectual 
property. Ultimately, we could be prevented from commercializing a product, or be forced, by court order or otherwise, to cease some 
or all aspects of our business operations, if, as a result of actual or threatened patent or other intellectual property claims, we are 
unable to enter into licenses on acceptable terms. Further, we could be found liable for significant monetary damages as a result of 
claims of intellectual property infringement. For example, we have received, and may in the future receive, offers to license and 
demands to license from third parties claiming that we are infringing their intellectual property or owe license fees and, even if such 
claims are without merit, we could fail to successfully avoid or settle such claims. 

If Teva, uniQure, Genentech or Merck license or otherwise acquire rights to intellectual property controlled by a third party in 

various circumstances, for example, where a product could not be legally developed or commercialized in a country without the third-
party intellectual property right or, where it is decided that it would be useful to acquire such third-party right to develop or 
commercialize the product, they are eligible under our collaboration agreements to decrease payments payable to us on a product-by-
product basis and, in certain cases, on a country-by-country basis. Any of the foregoing events could harm our business significantly. 

If we breach any of the agreements under which we license the use, development and commercialization rights to our product 

candidates or technology from third parties, we could lose license rights that are important to our business. 

Under our existing license agreements, we are subject to various obligations, including diligence obligations such as 

development and commercialization obligations, as well as potential royalty payments and other obligations. If we fail to comply with 
any of these obligations or otherwise breach our license agreements, our licensing partners may have the right to terminate the 
applicable license in whole or in part. Generally, the loss of any one of our current licenses, or any other license we may acquire in the 
future, could materially harm our business, prospects, financial condition and results of operations.  

55 

 
Confidentiality agreements with employees and third parties may not prevent unauthorized disclosure of trade secrets and other 

proprietary information, which would harm our competitive position. 

In addition to patents, we rely on trade secrets, technical know-how and proprietary information concerning our discovery 

platform, business strategy and product candidates in order to protect our competitive position, which are difficult to protect. In the 
course of our research and development activities and our business activities, we often rely on confidentiality agreements to protect 
our proprietary information. Such confidentiality agreements are used, for example, when we talk to vendors of laboratory or clinical 
development services or potential strategic collaborators. In addition, each of our employees and consultants is required to sign a 
confidentiality agreement and invention assignment agreement upon joining our company. Our employees, consultants, contractors, 
business partners or outside scientific collaborators might intentionally or inadvertently disclose our trade secret information in breach 
of these confidentiality agreements or our trade secrets may otherwise be misappropriated. Our collaborators might also have rights to 
publish data and we might fail to apply for patent protection prior to such publication. It is possible that a competitor will make use of 
such information, and that our competitive position will be compromised. In addition, to the extent that our employees, consultants or 
contractors use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting 
know-how and inventions. Enforcing a claim that a third party illegally obtained and is using any of our trade secrets is expensive and 
time consuming, and the outcome is unpredictable. In addition, courts outside the U.S. sometimes are less willing than U.S. courts to 
protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how. If we 
cannot maintain the confidentiality of our proprietary technology and other confidential information, then our ability to obtain patent 
protection or to protect our trade secret information would be jeopardized, which would adversely affect our competitive position. 

Patent reform legislation and recent court decisions could increase the uncertainties and costs surrounding the prosecution of 

our patent applications and the enforcement or defense of our issued patents. 

On September 16, 2011, the Leahy-Smith America Invents Act, or the Leahy-Smith Act, was signed into law. The Leahy-Smith 

Act includes a number of significant changes to U.S. patent law, including provisions that affect the way patent applications will be 
prosecuted and may also affect patent litigation. The USPTO has developed and implemented regulations and procedures to govern 
administration of the Leahy-Smith Act, and substantive changes to patent law associated with the Leahy-Smith Act. The full effect of 
these changes is currently unclear as the courts have yet to address these provisions and the applicability of the Leahy-Smith Act and 
new regulations on specific patents, including our patents discussed herein, have not been determined and would need to be reviewed. 
Accordingly, it is not yet clear what, if any, impact the Leahy-Smith Act will have on the operation of our business. As a result, the 
Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of patent applications 
and the enforcement or defense of issued patents, all of which could have a material adverse effect on our business and financial 
condition. On June 13, 2013, the U.S. Supreme Court decision in Association for Molecular Pathology v. Myriad Genetics, Inc., held 
that isolated DNA sequences are not patentable. In December 2014, the USPTO issued its Interim Guidance on Patent Subject Matter 
Eligibility, in which it extended Myriad's "marked difference" standard for patent subject matter eligibility to all potential natural 
products. This standard applies to patent claims that recite not only nucleic acids (such as DNA in Myriad), but also other subject 
matter that could be considered a natural product, such as peptides, proteins, extracts, organisms, antibodies, chemicals, and minerals. 
As a consequence of the Myriad decision and the USPTO’s Interim Guidance, if any of our future product candidates utilize isolated 
DNA, peptides, proteins or the like, we will not be able to obtain patents in the U.S. claiming such novel gene targets that we discover, 
which could limit our ability to prevent third parties from developing drugs directed against such targets.  

If we do not obtain protection under the Hatch-Waxman Act and similar legislation outside of the U.S. by extending the patent 

terms for our product candidates, our business may be materially harmed. 

Depending upon the timing, duration and specifics of FDA marketing approval of our product candidates, if any, one or more 

U.S. patents may be eligible for limited patent term restoration under the Hatch-Waxman Act. The Hatch-Waxman Act permits a 
patent restoration term of up to five years as compensation for patent term lost during clinical testing of the product and the 
subsequent FDA regulatory review process. However, we may not be granted an extension because of, for example, failing to apply 
within applicable deadlines, failing to apply prior to expiration of relevant patents or otherwise failing to satisfy applicable 
requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. 

If we are unable to obtain patent term extension or restoration or the term of any such extension is less than we request, the 

period during which we will have the right to exclusively market our product will be shortened and our competitors may obtain 
approval of competing products following our patent expiration, and our revenue could be reduced, possibly materially. 

56 

 
We have not registered our corporate name as a trademark in all of our potential markets, and failure to secure those 

registrations could adversely affect our business. 

Our corporate name, Xenon, has not been trademarked in each market where we operate and plan to operate. Our trademark 
applications for our corporate name or the name of our products may not be allowed for registration, and our registered trademarks 
may not be maintained or enforced. During trademark registration proceedings, we may receive rejections, which we may be unable to 
overcome in our responses. Third parties may also attempt to register trademarks utilizing the Xenon name on their products, and we 
may not be successful in preventing such usage. In addition, in the USPTO and in comparable agencies in many foreign jurisdictions, 
third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. 
Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may not survive such proceedings. If 
we do not secure registrations for our trademarks, we may encounter more difficulty in enforcing them against third parties than we 
otherwise would. 

Intellectual property litigation may lead to unfavorable publicity that harms our reputation and causes the market price of our 

common shares to decline. 

During the course of any intellectual property litigation, there could be public announcements of the initiation of the litigation as 
well as results of hearings, rulings on motions, and other interim proceedings in the litigation. If securities analysts or investors regard 
these announcements as negative, the perceived value of our existing products, programs or intellectual property could be diminished. 
Accordingly, the market price of our common shares may decline. Such announcements could also harm our reputation or the market 
for our future products, which could have a material adverse effect on our business. 

Risks Related to Our Industry 

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit 

commercialization of our current and any future products. 

We face an inherent risk of product liability as a result of the clinical testing of our product candidates, and we will face an even 
greater risk if we commercialize any product candidates. For example, we may be sued if any of our product candidates, including any 
that are developed in combination therapies, allegedly causes injury or is found to be otherwise unsuitable during product testing, 
manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in 
design, a failure to warn of dangers inherent in the product, negligence, strict liability and a breach of warranties. Claims could also be 
asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may 
incur substantial liabilities or be required to limit commercialization of our product candidates. Even successful defense would require 
significant financial and management resources. There is also risk that third parties we have agreed to indemnify could incur liability. 
Regardless of the merits or eventual outcome, liability claims may result in:

decreased demand for our product candidates or any resulting products; 

injury to our reputation; 

withdrawal of clinical trial participants; 

costs to defend the related litigation; 

a diversion of management’s time and our resources; 

substantial monetary awards to trial participants or patients; 

product recalls, withdrawals or labeling, marketing or promotional restrictions; 

loss of revenue; 

the inability to commercialize our product candidates; and 

a decline in the market price of our common shares. 

57 

 
We currently carry product liability insurance of $10,000,000 per occurrence and $10,000,000 aggregate limit. We believe our 
product liability insurance coverage is appropriate in light of our current clinical programs; however, we may not be able to maintain 
insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. If and when we obtain 
marketing approval for product candidates, we intend to expand our insurance coverage to include the sale of commercial products; 
however, we may then be unable to obtain product liability insurance on commercially reasonable terms or in adequate amounts. On 
occasion, large judgments have been awarded in class action lawsuits based on drugs or medical treatments that had unanticipated 
adverse effects. A successful product liability claim or series of claims brought against us could cause the market price of our common 
shares to decline and, if judgments exceed our insurance coverage, could adversely affect our future results of operations and business. 

Patients with certain of the diseases targeted by our product candidates are often already in severe and advanced stages of 
disease and have both known and unknown significant pre-existing and potentially life-threatening conditions. During the course of 
treatment, patients may suffer adverse events, including death, for reasons that may be related to our product candidates. Such events 
could subject us to costly litigation, require us to pay substantial amounts of money to injured patients, delay, negatively impact or end 
our opportunity to receive or maintain regulatory approval to market those product candidates, or require us to suspend or abandon our 
commercialization efforts. Even in a circumstance in which we do not believe that an adverse event is related to our products, the 
investigation into the circumstance may be time-consuming or inconclusive. These investigations may interrupt our sales efforts, delay 
our regulatory approval process in other countries, or impact and limit the type of regulatory approvals our product candidates receive 
or maintain. As a result of these factors, a product liability claim, even if successfully defended, could have a material adverse effect 
on our business, financial condition or results of operations. 

Our current and future relationships with customers and third-party payers in the U.S. and elsewhere will be subject, directly or 

indirectly, to applicable federal and state anti-kickback, fraud and abuse, false claims, transparency, health information privacy 
and security, and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual 
damages, reputational harm, administrative burdens, and diminished profits and future earnings. 

Healthcare providers, physicians and third-party payers in the U.S. and elsewhere play a primary role in the recommendation 

and prescription of any product candidates for which we obtain marketing approval. Our future arrangements with third-party payers 
and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations, including, without 
limitation, the federal Anti-Kickback Statute and the federal False Claims Act, that may constrain the business or financial 
arrangements and relationships through which we market, sell and distribute any products for which we obtain marketing approval. In 
addition, we may be subject to transparency laws and patient privacy regulation by the federal government and by the U.S. states and 
foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws and regulations that 
may affect our ability to operate include the following: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, 
offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the 
referral of an individual for, or the purchase, order or recommendation of, any good or service for which payment may be 
made under federal and state healthcare programs such as Medicare and Medicaid; 

federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act, which 
impose criminal and civil penalties, including civil whistleblower or qui tam actions, against individuals or entities for 
knowingly presenting, or causing to be presented, to the federal government, including the Medicare and Medicaid 
programs, or other third party payers claims for payment that are false or fraudulent or making a false statement to avoid, 
decrease or conceal an obligation to pay money to the federal government; 

HIPAA, which imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program and 
making false statements relating to healthcare matters; 

HIPAA, as amended by HITECH, and their respective implementing regulations, which impose obligations on covered 
healthcare providers, health plans, and healthcare clearinghouses, as well as their business associates that create, receive, 
maintain, or transmit individually identifiable health information for or on their behalf, with respect to safeguarding the 
privacy, security and transmission of individually identifiable health information; 

58 

 
(cid:120) 

(cid:120) 

the federal Open Payments program; and 

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to 
sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-
party payers, including private insurers; state and foreign laws that require pharmaceutical companies to comply with the 
pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the 
federal government or otherwise restrict payments that may be made to healthcare providers; state and foreign laws that 
require drug manufacturers to report information related to payments to physicians and other healthcare providers or 
marketing expenditures; and state and foreign laws governing the collection, export, privacy, use and security of 
biological materials and health information in certain circumstances, many of which differ from each other in significant 
ways and may not have the same effect, thus complicating compliance efforts. 

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations 

may involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply 
with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If 
our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be 
subject to significant civil, criminal and administrative penalties, including, without limitation, damages, fines, imprisonment, 
exclusion from participation in government healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring 
of our operations, which could have a material adverse effect on our business. If any of the physicians or other providers or entities 
with whom we expect to do business, including our collaborators, is found not to be in compliance with applicable laws, it may be 
subject to criminal, civil or administrative sanctions, including exclusions from participation in government healthcare programs, 
which could also materially affect our business. 

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or 

incur costs that could have a material adverse effect on the success of our business. 

Our research and development activities involve the controlled use of potentially harmful biological materials as well as 
hazardous materials, chemicals, and various radioactive compounds typically employed in molecular and cellular biology. For 
example, we routinely use cells in culture and we employ small amounts of radioisotopes. We cannot completely eliminate the risk of 
accidental contamination or injury from the use, storage, handling, or disposal of these materials through our maintenance of up-to-
date licensing and training programs. In the event of contamination or injury, we could be held liable for damages that result, and any 
liability could exceed our resources. We currently carry insurance covering certain claims arising from our use of these materials. 
However, if we are unable to maintain our insurance coverage at a reasonable cost and with adequate coverage, our insurance may not 
cover any liability that may arise. We are subject to U.S. and Canadian federal, provincial, and local laws and regulations governing 
the use, storage, handling, and disposal of these materials and specified waste products. Complying with regulations regarding the use 
of these materials could be costly, and if we fail to comply with these regulations, it could have a material adverse effect on our 
operations and profitability. 

We or the third parties upon whom we depend may be adversely affected by earthquakes or other natural disasters and our 

business continuity and disaster recovery plans may not adequately protect us from serious disaster. 

Our headquarters are located in Burnaby, British Columbia, Canada. We are vulnerable to natural disasters such as earthquakes 
that could disrupt our operations. If a natural disaster, power outage, fire or other event occurred that prevented us from using all or a 
significant portion of our headquarters, that damaged critical infrastructure, such as the manufacturing facilities of our third-party 
contract manufacturers, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our 
business for a substantial period of time. Although we carry insurance for earthquakes and other natural disasters, we may not carry 
sufficient business interruption insurance to compensate us for all losses that may occur. The disaster recovery and business continuity 
plans we have in place currently are limited and may not be adequate in the event of a serious disaster or similar event. We may incur 
substantial expenses as a result of a natural disaster or earthquake, which could have a material adverse effect on our business. In 
addition, we may lose samples or other valuable data. The occurrence of any of the forgoing could have a material adverse effect on 
our business.

Risks Related to Our Common Shares 

The market price of our common shares may be volatile, and purchasers of our common shares could incur substantial losses. 

The market price of our common shares has fluctuated in the past and is likely to be volatile in the future. As a result of this 
volatility, investors may experience losses on their investment in our common shares. The market price for our common shares may be 
influenced by many factors, including the following:

actions by any of our collaborators regarding our product candidates they are developing, including announcements 
regarding clinical or regulatory decisions or developments or our collaboration; 

announcements by us or our competitors of new products, product candidates or new uses for existing products, 
significant contracts, commercial relationships or capital commitments and the timing of these introductions or 
announcements; 

unanticipated serious safety concerns related to the use of any of our products and product candidates; 

results from or delays of clinical trials of our product candidates; 

failure to obtain or delays in obtaining or maintaining product approvals or clearances from regulatory authorities; 

adverse regulatory or reimbursement announcements; 

announcements by us or our competitors of significant acquisitions, strategic collaborations, joint ventures or capital 
commitments; 

the results of our efforts to discover or develop additional product candidates; 

our dependence on third parties, including our collaborators, CROs, clinical trial sponsors and clinical investigators; 

regulatory or legal developments in Canada, the U.S. or other countries; 

developments or disputes concerning patent applications, issued patents or other proprietary rights; 

the recruitment or departure of key scientific or management personnel; 

our ability to successfully commercialize our future product candidates we develop independently, if approved; 

the level of expenses related to any of our product candidates or clinical development programs; 

actual or anticipated changes in estimates as to financial results, development timelines or recommendations by securities 
analysts; 

actual or anticipated quarterly variations in our financial results or those of our competitors; 

any change to the composition of the board of directors or key personnel; 

sales of common shares by us or our shareholders in the future, as well as the overall trading volume of our common 
shares; 

changes in the structure of healthcare payment systems; 

commencement of, or our involvement in, litigation; 

general economic, industry and market conditions in the pharmaceutical and biotechnology sectors and other factors that 
may be unrelated to our operating performance or the operating performance of our competitors, including changes in 
market valuations of similar companies; and 

(cid:120) 

the other factors described in this “Risk Factors” section. 

In addition, the stock market in general, and NASDAQ and the biopharmaceutical industry in particular, have from time to time 

experienced volatility that often has been unrelated to the operating performance of the underlying companies. These broad market 
and industry fluctuations may adversely affect the market price of our common shares, regardless of our operating performance. In 
several recent situations where the market price of a stock has been volatile, holders of that stock have instituted securities class action 
litigation against the company that issued the stock. If any of our shareholders were to bring a lawsuit against us, the defense and 
disposition of the lawsuit could be costly and divert the time and attention of our management and harm our operating results. 

60 

 
Future sales of our common shares in the public market could cause the market price of our common shares to fall. 

The market price of our common shares could decline as a result of sales of a large number of our common shares or the 
perception that these sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for 
us to sell equity securities in the future at a time and at a price that we deem appropriate. 

Certain holders of our common shares are party to our amended and restated investor rights agreement, as amended, and have 
rights, subject to some conditions, to require us to file registration statements covering the sale of their common shares or to include 
their common shares in registration statements that we may file for ourselves or other shareholders. We also register the offer and sale 
of all common shares that we may issue under our equity compensation plans. 

In addition, in the future, we may issue additional common shares or other equity or debt securities convertible into common 
shares in connection with a financing, acquisition, litigation settlement, employee arrangements or otherwise. Any such issuance could 
result in substantial dilution to our existing shareholders and could cause the market price of our common shares to decline. 

Provisions in our corporate charter documents and Canadian law could make an acquisition of us, which may be beneficial to 

our shareholders, more difficult and may prevent attempts by our shareholders to replace or remove our current management 
and/or limit the market price of our common shares. 

Provisions in our articles and our by-laws, as well as certain provisions under the Canada Business Corporations Act, or CBCA, 

and applicable Canadian securities laws, may discourage, delay or prevent a merger, acquisition or other change in control of us that 
shareholders may consider favorable, including transactions in which they might otherwise receive a premium for their common 
shares. These provisions could also limit the price that investors might be willing to pay in the future for our common shares, thereby 
depressing the market price of our common shares. In addition, because our board of directors is responsible for appointing the 
members of our management team, these provisions may frustrate or prevent any attempts by our shareholders to replace or remove 
our current management by making it more difficult for shareholders to replace members of our board of directors. Among other 
things, these provisions include the following: 

(cid:120) 

(cid:120) 

(cid:120) 

shareholders cannot amend our articles unless such amendment is approved by shareholders holding at least two-thirds of 
the shares entitled to vote on such approval; 

our board of directors may, without shareholder approval, issue preferred shares having any terms, conditions, rights, 
preferences and privileges as the board of directors may determine; and 

shareholders must give advance notice to nominate directors or to submit proposals for consideration at shareholders’ 
meetings. 

Any provision in our articles, by-laws, under the CBCA or under any applicable Canadian securities law that has the effect of 

delaying or deterring a change in control could limit the opportunity for our shareholders to receive a premium for their common 
shares, and could also affect the price that some investors are willing to pay for our common shares. 

U.S. civil liabilities may not be enforceable against us, our directors, or our officers. 

We are governed by the CBCA and our principal place of business is in Canada. Many of our directors and officers reside 
outside of the U.S., and all or a substantial portion of their assets as well as all or a substantial portion of our assets are located outside 
the U.S. As a result, it may be difficult for investors to effect service of process within the U.S. upon us and certain of our directors 
and officers or to enforce judgments obtained against us or such persons, in U.S. courts, in any action, including actions predicated 
upon the civil liability provisions of U.S. federal securities laws or any other laws of the U.S. Additionally, rights predicated solely 
upon civil liability provisions of U.S. federal securities laws or any other laws of the U.S. may not be enforceable in original actions, 
or actions to enforce judgments obtained in U.S. courts, brought in Canadian courts, including courts in the Province of British 
Columbia. 

61 

 
We are governed by the corporate laws of Canada which in some cases have a different effect on shareholders than the 

corporate laws of Delaware, U.S. 

We are governed by the CBCA and other relevant laws, which may affect the rights of shareholders differently than those of a 

company governed by the laws of a U.S. jurisdiction, and may, together with our charter documents, have the effect of delaying, 
deferring or discouraging another party from acquiring control of our company by means of a tender offer, a proxy contest or 
otherwise, or may affect the price an acquiring party would be willing to offer in such an instance. The material differences between 
the CBCA and Delaware General Corporation Law, or DGCL, that may have the greatest such effect include, but are not limited to, 
the following: (i) for material corporate transactions (such as mergers and amalgamations, other extraordinary corporate transactions 
or amendments to our articles) the CBCA generally requires a two-thirds majority vote by shareholders, whereas DGCL generally 
only requires a majority vote; and (ii) under the CBCA a holder of 5% or more of our common shares can requisition a special 
meeting of shareholders, whereas such right does not exist under the DGCL. 

An active trading market for our common shares may not be maintained. 

Our common shares are currently traded on NASDAQ, but we can provide no assurance that we will be able to maintain an 
active trading market on NASDAQ or any other exchange in the future. If an active market for our common shares is not maintained, 
it may be difficult for our shareholders to sell the common shares they have purchased without depressing the market price for the 
common shares or at all. Further, an inactive market may also impair our ability to raise capital by selling additional common shares 
and may impair our ability to enter into strategic collaborations or acquire companies or products by using our common shares as 
consideration. 

Complying with the laws and regulations affecting public companies will increase our costs and the demands on management 

and could harm our operating results and our ability to accurately report our financial condition, results of operations or cash 
flows, which may adversely affect investor confidence in us and, as a result, the value of our common shares. 

As a public company, and particularly after we cease to be an “emerging growth company,” we will incur significant legal, 
accounting and other expenses. In addition, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and the related rules and 
regulations subsequently implemented by the Securities and Exchange Commission, or SEC, the applicable Canadian securities 
regulators and NASDAQ impose numerous requirements on public companies, including requiring changes in corporate governance 
practices. Also, the Securities Exchange Act of 1934, as amended, or the Exchange Act, requires, among other things, that we file 
annual, quarterly and current reports with respect to our business and operating results. Our management and other personnel have and 
will continue to devote a substantial amount of time to compliance with these laws and regulations. These requirements have increased 
and will continue to increase our legal, accounting, and financial compliance costs and have made and will continue to make some 
activities more time-consuming and costly. For example, these rules and regulations make it difficult and expensive for us to maintain 
director and officer liability insurance and we may be required to accept reduced policy limits and coverage or to incur substantial 
costs to maintain the same or similar coverage. These rules and regulations could also make it more difficult for us to attract and retain 
qualified persons to serve on our board of directors or our board committees or as executive officers. 

The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial 

reporting annually and the effectiveness of our disclosure controls and procedures quarterly. In particular, Section 404 of the 
Sarbanes-Oxley Act, or Section 404, requires us to perform system and process evaluation and testing of our internal control over 
financial reporting to allow management to report on, and our independent registered public accounting firm potentially to attest to, 
the effectiveness of our internal control over financial reporting. As an “emerging growth company” we expect to avail ourselves of 
the exemption from the requirement that our independent registered public accounting firm attest to the effectiveness of our internal 
control over financial reporting under Section 404. However, we may no longer avail ourselves of this exemption when we cease to be 
an “emerging growth company.” When our independent registered public accounting firm is required to undertake an assessment of 
our internal control over financial reporting, the cost of our compliance with Section 404 will correspondingly increase. Our 
compliance with applicable provisions of Section 404 will require that we incur substantial accounting expense and expend significant 
management time on compliance-related issues as we implement additional corporate governance practices and comply with reporting 
requirements. Moreover, if we are not able to comply with the requirements of Section 404 applicable to us in a timely manner, or if 
we or our independent registered public accounting firm identifies deficiencies in our internal control over financial reporting that are 
deemed to be material weaknesses, the market price of our common shares could decline and we could be subject to sanctions or 
investigations by the SEC or other regulatory authorities, which would require additional financial and management resources. 

62 

 
Furthermore, investor perceptions of our company may suffer if deficiencies are found, and this could cause a decline in the 
market price of our common shares. Irrespective of compliance with Section 404, any failure of our internal control over financial 
reporting could have a material adverse effect on our stated operating results and harm our reputation. If we are unable to implement 
these requirements effectively or efficiently, it could harm our operations, financial reporting, or financial results and could result in 
an adverse opinion on our internal controls from our independent registered public accounting firm. 

We are an “emerging growth company,” and any decision on our part to comply only with certain reduced reporting and 
disclosure requirements applicable to emerging growth companies could make our common shares less attractive to investors. 

We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. For as 

long as we continue to be an “emerging growth company,” we may choose to take advantage of exemptions from various reporting 
requirements applicable to other public companies that are not “emerging growth companies,” including, but not limited to, not being 
required to have our independent registered public accounting firm audit our internal control over financial reporting under 
Section 404, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and 
exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any 
golden parachute payments not previously approved. We could be an “emerging growth company” for up to five years following the 
completion of our initial public offering, although, if we have more than $1.0 billion in annual revenue, if the market value of our 
common shares held by non-affiliates exceeds $700 million as of June 30 of any year, or we issue more than $1.0 billion of non-
convertible debt over a three-year period before the end of that five-year period, we would cease to be an “emerging growth company” 
as of the following December 31. Investors could find our common shares less attractive if we choose to rely on these exemptions. If 
some investors find our common shares less attractive as a result of any choices to reduce future disclosure, there may be a less active 
trading market for our common shares and the market price of our common shares may be more volatile. 

As an “emerging growth company,” the JOBS Act allows us to delay adoption of new or revised accounting pronouncements 

applicable to public companies until such pronouncements are made applicable to private companies. However, we previously decided 
to “opt out” of such extended transition period, and as a result, we will comply with new or revised accounting standards on the 
relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act 
provides that our decision to opt out of the extended transition period for complying with new or revised accounting standards is 
irrevocable. 

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report 
our financial results or prevent fraud. As a result, shareholders could lose confidence in our financial and other public reporting, 
which would harm our business and the market price of our common shares. 

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with 

adequate disclosure controls and procedures, are designed to prevent fraud. Any failure to implement required new or improved 
controls, or difficulties encountered in their implementation could cause us to fail to meet our reporting obligations. In addition, any 
testing by us conducted in connection with Section 404 or any subsequent testing by our independent registered public accounting 
firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that may 
require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement. 
Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a 
negative effect on the market price of our common shares. 

We are required to disclose changes made in our internal controls and procedures on a quarterly basis and our management is 
required to assess the effectiveness of these controls annually. However, for as long as we are an “emerging growth company” under 
the JOBS Act, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal 
controls over financial reporting pursuant to Section 404. An independent assessment of the effectiveness of our internal controls 
could detect problems that our management’s assessment might not. In addition, our management did not perform an evaluation of our 
internal control over financial reporting as of December 31, 2014 or December 31, 2013 and our independent registered public 
accounting firm did not perform an evaluation of our internal control over financial reporting during any period in accordance with the 
provisions of the Sarbanes-Oxley Act. Had we and our independent registered public accounting firm performed such an evaluation, 
control deficiencies may have been identified by management or our independent registered public accounting firm, and those control 
deficiencies could have also represented one or more material weaknesses. Undetected material weaknesses in our internal controls 
could lead to financial statement restatements and require us to incur the expense of remediation. 

63 

 
Future sales and issuances of our common shares or rights to purchase common shares, including pursuant to our equity 

incentive plans, could cause you to incur dilution and could cause the market price of our common shares to fall. 

As of December 31, 2016, options to purchase 1,910,823 of our common shares with a weighted-average exercise price of $7.32 

per common share were outstanding. The exercise of any of these options would result in dilution to current shareholders. Further, 
because we will need to raise additional capital to fund our clinical development programs, we may in the future sell substantial 
amounts of common shares or securities convertible into or exchangeable for common shares. Pursuant to our equity incentive plans, 
our compensation committee (or a subset or delegate thereof) is authorized to grant equity-based incentive awards to our employees, 
directors and consultants. Future option grants and issuances of common shares under our share-based compensation plans may have 
an adverse effect on the market price of our common shares. 

These future issuances of common shares or common share-related securities, together with the exercise of outstanding options 

and any additional common shares issued in connection with acquisitions, if any, may result in further dilution to our existing 
shareholders, and new investors could gain rights, preferences and privileges senior to those of holders of our common shares. 

We are at risk of securities class action litigation. 

In the past, securities class action litigation has often been brought against a company following a decline in the market price of 

its securities. This risk is especially relevant for us because biotechnology companies have experienced significant stock price 
volatility in recent years. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and 
resources, which could harm our business. 

NASDAQ may delist our securities from its exchange, which could limit investors’ ability to make transactions in our securities 

and subject us to additional trading restrictions. 

Our common shares are listed on NASDAQ under the trading symbol “XENE.” Our securities may fail to meet the continued 
listing requirements to be listed on NASDAQ. If NASDAQ delists our common shares from trading on its exchange, we could face 
significant material adverse consequences, including: 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

significant impairment of the liquidity for our common shares, which may substantially decrease the market price of our 
common shares; 

a limited availability of market quotations for our securities; 

a determination that our common shares qualify as a “penny stock” which will require brokers trading in our common 
shares to adhere to more stringent rules and possibly resulting in a reduced level of trading activity in the secondary 
trading market for our common shares; 

a limited amount of news and analyst coverage for our company; and 

a decreased ability to issue additional securities or obtain additional financing in the future. 

If securities or industry analysts do not publish research reports about our business, or if they issue an adverse opinion about 

our business, the market price of our common shares and the trading volume of our common shares could decline. 

The trading market for our common shares is influenced by the research and reports that securities or industry analysts publish 
about us or our business. If too few securities or industry analysts cover our company, the market price of our common shares would 
likely be negatively impacted. If securities and industry analysts who cover us downgrade our common shares or publish inaccurate or 
unfavorable research about our business, the market price of our common shares would likely decline. If one or more of these analysts 
cease coverage of our company or fail to publish reports on us regularly, demand for our common shares could decrease, which might 
cause the market price of our common shares and the trading volume of our common shares to decline. 

64 

 
Our management team has broad discretion as to the use of the net proceeds from our September 2016 public offering of 
common shares and the investment of these proceeds may not yield a favorable return. We may invest the proceeds in ways with 
which our shareholders disagree. 

We have broad discretion in the application of the net proceeds to us from our September 2016 public offering of common 
shares. You may not agree with our decisions, and our use of the proceeds and our existing cash and cash equivalents and marketable 
securities may not improve our results of operation or enhance the value of our common shares. The results and effectiveness of the 
use of proceeds are uncertain, and we could spend the proceeds in ways that you do not agree with or that do not improve our results 
of operations or enhance the value of our common shares. Our failure to apply these funds effectively could have a material adverse 
effect on our business, delay the development of our product candidates and cause the market price of our common shares to decline. 
In addition, until the net proceeds are used, they may be placed in investments that do not produce significant income or that may lose 
value. 

We do not anticipate paying any cash dividends on our common shares in the foreseeable future. 

We do not currently intend to pay any cash dividends on our common shares in the foreseeable future. We currently intend to 
retain all of our future earnings, if any, to finance the growth and development of our business. In addition, the terms of any future 
debt agreements may preclude us from paying dividends. As a result, capital appreciation, if any, of our common shares may be 
investors’ sole source of gain for the foreseeable future. 

Item 1B.   Unresolved Staff Comments 

None. 

Item 2. 

Properties 

Our headquarters are located in Burnaby, British Columbia, where we occupy approximately 41,332 square feet of office and 

laboratory space. The term of the lease expires in March 2022. We currently pay an aggregate of approximately $95,496 per month in 
base rent, property tax, common area maintenance fees and management fees, and the landlord holds a security deposit equal to 
approximately $68,623. 

Our temporary U.S. office is located in Boston, Massachusetts, where we occupy on a month-to-month basis approximately 134 

square feet. 

We believe that our existing facilities are adequate to meet our business requirements for the near-term and that additional space 

will be available on commercially reasonable terms, if required.  

Item 3. 

Legal Proceedings 

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our 

business. We are not presently a party to any legal proceedings that, in the opinion of our management, would reasonably be expected 
to have a material adverse effect on our business, financial condition, operating results or cash flows if determined adversely to us. 
Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of 
management resources and other factors.

On March 3, 2017, the last reported sale price of our common shares was $8.60 per share. 

Holders 

As of March 3, 2017, there were approximately 176 holders of record of our common shares. The actual number of shareholders 
is greater than this number of record holders and includes shareholders who are beneficial owners but whose common shares are held 
in street name by brokers and other nominees. 

Dividends 

We have never declared or paid any cash dividends on our common shares or any other securities. We currently anticipate that 
we will retain all available funds and any future earnings, if any, in the foreseeable future for use in the operation of our business and 
do not currently anticipate paying cash dividends in the foreseeable future. Payment of future cash dividends, if any, will be at the 
discretion of the board of directors, subject to applicable law and will depend on various factors, including our financial condition, 
operating results, current and anticipated cash needs, the requirements of current or then-existing debt instruments and other factors 
the board of directors deems relevant. 

Canadian withholding tax at a rate of 25% (subject to reduction under the provisions of any applicable income tax treaty or 
convention to which Canada is a signatory) will be payable on the gross amount of dividends on our common shares paid or credited, 
or deemed to be paid or credited, to a holder of our common shares who, for purposes of the Income Tax Act (Canada), is not (and is 
not deemed to be) resident in Canada and who does not use or hold (and will not be deemed to use or hold) our common shares in, or 
in the course of, carrying on a business or part of a business in Canada, or a Non-Resident of Canada Holder. The Canadian 
withholding taxes will be deducted directly by us or our paying agent from the amount of the dividend otherwise payable and remitted 
to the Receiver General of Canada. The rate of withholding tax applicable to a dividend paid on our common shares to a Non-Resident 
of Canada Holder who is a resident of the U.S. for purposes of the Canada-U.S. Tax Convention, or the Convention, beneficially owns 
the dividend and qualifies for the full benefits of the Convention will generally be reduced to 15% or, if such a Non-Resident of 
Canada Holder is a corporation that owns (or, for purposes of the Convention, is considered to own) at least 10% of our voting shares, 
to 5%. Not all persons who are residents of the U.S. for purposes of the Convention will qualify for the benefits of the Convention. A 
Non-Resident of Canada Holder who is a resident of the U.S. is advised to consult his or her tax advisor in this regard. The rate of 
withholding tax on dividends is also reduced under other bilateral income tax treaties to which Canada is a signatory.

Item 7.  Management’s Discussion and Analysis of Financial Condition and Results of Operations 

You should read the following discussion and analysis together with Part II, Item 6 — “Selected Financial Data” and our 

consolidated financial statements and notes included elsewhere in this Annual Report. The following discussion contains forward-
looking statements that involve risks and uncertainties. Our actual results could differ from those expressed or implied in any 
forward-looking statements as a result of various factors, including those set forth under the caption Part I, Item 1A — “Risk 
Factors.” Throughout this discussion, unless the context specifies or implies otherwise, the terms “Xenon,” “we,” “us,” and “our” 
refer to Xenon Pharmaceuticals Inc. and its subsidiary. 

Overview 

We are a clinical-stage biopharmaceutical company discovering and developing a pipeline of differentiated therapeutics for 
orphan indications that we intend to commercialize on our own, and for larger market indications that we intend to partner with global 
pharmaceutical companies. We have expertise in human genetics, small molecule drug discovery, as well as preclinical and clinical 
development that we intend to leverage to develop innovative therapeutics, including novel selective ion channel inhibitors.  

Our pharmaceutical partners include Teva Pharmaceutical Industries, Ltd., or Teva (through its subsidiary, Ivax International 
GmbH), Genentech, a member of the Roche Group, and Merck & Co., Inc., or Merck (through its affiliate, Essex Chemie AG). Our 
pharmaceutical collaborations have generated in aggregate over $160.0 million in non-equity funding to date with the potential to 
provide us with over $1.0 billion in future milestone payments, as well as royalties and co-promotion income on product sales. 

Our proprietary development pipeline and pharmaceutical partnerships include:

(cid:120) 

XEN801 is a stearoyl Co-A desaturase-1, or SCD1, inhibitor being developed for the treatment of acne. SCD1 is an 
enzyme involved in lipid synthesis that is expressed in sebaceous glands in the skin. We have completed enrollment in a 
Phase 2 clinical trial in patients with moderate to severe facial acne, and anticipate topline results in the latter part of the 
first quarter of 2017;  

XEN901 is a potent, selective Nav1.6 inhibitor being developed for the treatment of rare infantile epileptic 
encephalopathies and other forms of epilepsy. We expect to file an investigational new drug, or IND, or an IND 
equivalent application in the fourth quarter of 2017; 

Our collaborator Teva is developing TV-45070, which is a topical sodium channel inhibitor for the treatment of 
neuropathic pain. Teva is currently conducting a randomized, double-blind, placebo-controlled Phase 2b clinical trial of 
TV-45070 in patients with post-herpetic neuralgia, or PHN, with topline results expected in mid-2017;  

Our collaborator Genentech has completed two Phase 1 clinical trials for GDC-0276 and GDC-0310, which are both oral, 
selective Nav1.7 small-molecule inhibitors. Genentech has indicated that it intends to focus its ongoing development 
efforts on GDC-0310. Pending a full assessment of the Phase 1 clinical results and ongoing in vivo studies, Genentech 
anticipates initiating a Phase 2 clinical trial in 2017 for the potential treatment of pain; and 

Our licensee uniQure Biopharma B.V., or uniQure, has developed Glybera for the treatment of the orphan disorder 
lipoprotein lipase deficiency, or LPLD. Glybera was the first gene therapy product approved in the European Union, or 
the EU. In November 2015, the first patient treated with Glybera as a commercially available gene therapy was announced 
by uniQure and enabled by its commercialization partner in the EU, Chiesi Farmaceutici S.p.A., or Chiesi, which has sole 
control over commercialization in the EU.  

We have funded our operations through the sale of equity securities, funding received from our licensees and collaborators and, 

to a lesser extent, government funding. For 2016, 2015, and 2014, we recognized revenues of approximately $1.8 million, $15.6 
million, and $28.4 million, respectively, consisting primarily of funding from our collaborators. Though our revenue from our 
collaboration and license agreements resulted in net income of $13.0 million for the year ended December 31, 2014 and $12.0 million 
for the year ended December 31, 2013, we do not expect to have sustained profitability for the foreseeable future. We had net losses of 
$23.0 million for the year ended December 31, 2016 and an accumulated deficit of $142.7 million as of December 31, 2016, from 
expenses incurred in connection with our research programs and from general and administrative costs associated with our operations. 

Other than royalties we are eligible to receive from sales of Glybera under our license to uniQure, which we do not expect to be 

significant, we have not generated any royalty revenue from product sales, and do not otherwise anticipate generating revenue from 
product sales for the foreseeable future, if ever. We expect that our revenue in the near term will be substantially dependent on our 
collaboration agreements. Given the uncertain nature of clinical development of our current and future product candidates and the 
commercialization of current and future products, we cannot predict when or whether we will receive further milestone payments 
under our current or future collaboration agreements or whether we will be able to report either revenue or net income in future years.

We expect to continue to incur significant expenses and operating losses for at least the next 12 to 24 months. We anticipate that 

our expenses will increase as we:

continue our research and preclinical and clinical development of our product candidates either from our internal research 
efforts or through acquiring or in-licensing other product candidates or technologies; 

seek regulatory and marketing approvals for any of our product candidates that successfully complete clinical trials; 

make milestone and other payments under our in-license agreements; 

maintain, protect and expand our intellectual property portfolio; 

attract, hire and retain skilled personnel; and 

create additional infrastructure to support our operations and otherwise. 

Financial Operations Overview 

Revenue 

To date, our revenue has been primarily derived from collaboration and licensing agreements as well as, to a lesser extent, 
government funding. In addition, we have received nominal royalties from a diagnostic license. Other than royalties we are eligible to 
receive from sales of Glybera under our license to uniQure, which we do not expect to be significant, we have not generated any 
royalty revenue from product sales, and do not otherwise anticipate generating revenue from product sales for the foreseeable future, if 
ever. We have entered into several collaboration agreements, the most significant of which, with respect to revenue, are described at 
“Business – Strategic Alliances” and “Note 9” of the consolidated financial statements included elsewhere in this Annual Report on 
Form 10-K. 

The following table is a summary of revenue recognized from our current collaboration and licensing agreements for each of the 

years ended December 31, 2016, 2015 and 2014 (in thousands):

Through December 31, 2016, we had recognized upfront fees and milestone payments totaling CAD$1.1 million, pursuant to 
our sublicense and research agreement with uniQure. We are eligible to receive certain additional milestone payments of less than 
CAD$1.0 million for Glybera and for each subsequent product, if any, developed pursuant to the agreement. 

Pursuant to the terms of our collaborative development and license agreement with Teva, we received an upfront payment of 

$41.0 million. We determined that the various deliverables under this agreement should be considered as a single unit of accounting. 
As such, the $41.0 million upfront payment was recognized as revenue ratably over the expected period of research performance of 
pre-commercial activities, which was the three-year period from December 2012 through December 2015. 

Pursuant to the terms of our December 2011 collaborative development and license agreement with Genentech, we received an 
upfront payment of $10.0 million. We determined that the various deliverables under this agreement should be considered as a single 
unit of accounting. As such, the $10.0 million upfront payment was recognized as revenue ratably over the expected period of research 
performance, which was the three-year period from December 2011 through December 2014. In August 2014, we recognized a $7.9 
million milestone payment for the approval of the GDC-0276 Clinical Trial Application by Health Canada. We recognized the 
milestone payment upon achievement in August 2014.

Pursuant to the terms of our March 2014 agreement with Genentech, we received an upfront payment of $1.5 million. We 

determined that the various deliverables under this agreement should be considered as a single unit of accounting. As such, the 
$1.5 million upfront payment was recognized as revenue ratably over the expected period of research performance, which was the 
two-year period from March 2014 to March 2016. In September 2015, we received a $0.25 million milestone payment for the 
identification of a novel pain target under this agreement. We recognized the milestone payment upon achievement in September 
2015. 

As our other internal and partnered products are in various stages of clinical and preclinical development, we do not expect to 

generate any revenue from product sales other than from our share of revenue related to our agreement with uniQure, which we do not 
expect to be significant, for at least the next several years. We expect that revenue for the next several years will be derived from 
milestone payments under our current collaboration agreements and any additional collaboration agreements that we may enter into in 
the future. We cannot provide any assurance as to the extent or timing of future milestone payments or royalty payments or that we 
will receive any future payments at all. 

We expect that any revenue we generate will fluctuate quarter to quarter as a function of the timing and amount of milestones 

and other payments from our existing collaborations and any future collaborations.

Research and development expenses represent costs incurred to conduct research and development of our other proprietary 

product candidates, as well as to support research and development on our product candidates in collaboration with Teva and 
Genentech. 

Research and development expenses consist of costs incurred in performing research and development activities, including 
salary, related benefits and stock-based compensation for employees engaged in scientific research and development, third-party 
contract costs relating to research, formulation, manufacturing, preclinical studies and clinical trial activities, third-party license and 
collaboration fees, laboratory consumables and allocated facility-related and information technology costs. 

Project-specific expenses reflect costs directly attributable to our clinical development candidates and our preclinical candidates 

once nominated and selected for further development. All remaining research and development expenses are reflected in early-stage 
discovery programs. At any given time, we have several active early-stage research and drug discovery programs. Our personnel and 
infrastructure are typically deployed over multiple projects and are not directly linked to any individual internal early-stage research or 
drug discovery program. Therefore, we do not maintain financial information for our internal early-stage research and internal drug 
discovery programs on a project-specific basis.

We expense all research and development costs as incurred. We expect that our research and development expenses will 

increase in the future as we advance our proprietary product candidates through clinical development, advance our internal drug 
discovery programs into preclinical development and continue our early-stage research. The increase in expense will likely include 
added personnel and third-party contracts related to research, formulation, manufacturing, preclinical studies and clinical trial 
activities as well as third-party license and collaboration fees and laboratory consumables. 

Clinical development timelines, likelihood of regulatory approval and commercialization and associated costs are uncertain and 
difficult to estimate and can vary significantly. We anticipate determining which research and development projects to pursue as well 
as the level of funding available for each project based on the scientific research and preclinical and clinical results of each product 
candidate and related regulatory action. We expect our research and development expenses to continue to represent our largest 
category of operating expense for at least the next 12 to 24 months. 

General and Administrative Expenses 

General and administrative expenses consist primarily of salary, related benefits and stock-based compensation of our executive, 

finance, legal, business development and administrative functions, travel expenses, allocated facility-related and information 
technology costs not otherwise included in research and development expenses, director compensation, director’s and officer’s 
insurance premiums, investor relations costs and professional fees for auditing, tax and legal services, including legal expenses for 
intellectual property protection. General and administrative expenses also include fair value adjustments of certain liability classified 
stock option awards.  

We expect that general and administrative expenses will increase in the future as we expand our operating activities to support 
increased research and development activities, and the potential build of commercial infrastructure for our option for co-promotion of 
TV-45070 in the U.S., if and when regulatory approval is received.  

Other Income (Expense) 

Interest Income. Interest income consists of income earned on our cash and investment balances. Our interest income has not 
been significant due to the levels of cash and investment balances and low interest earned on such balances. We anticipate that our 
interest income will continue to fluctuate depending on timing of payments from collaborative partners, our cash and investment 
balances, and interest rates. 

Foreign Exchange Gain (Loss). On January 1, 2015, our functional currency changed from the Canadian dollar to the U.S. 
dollar based on our analysis of the changes in the primary economic environment in which we operate. For the years ended December 
31, 2016 and 2015, net foreign exchange gains and losses consisted of gains and losses from the impact of foreign exchange 
fluctuations on our monetary assets and liabilities that were denominated in currencies other than the U.S. dollar (principally the 
Canadian dollar) whereas for the year ended December 31, 2014, net foreign exchange gains and losses consisted of gains and losses 
from the impact of foreign exchange fluctuations on our monetary assets and liabilities that were denominated in currencies other than 
the Canadian dollar (principally the U.S. dollar). We will continue to incur substantial expenses in Canadian dollars and will remain 
subject to risks associated with foreign currency fluctuations. See “Quantitative and Qualitative Disclosures About Market Risk – 
Foreign Currency Exchange Risk” below for additional information. 

Critical Accounting Policies and Significant Judgments and Estimates 

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated 

financial statements, which have been prepared in conformity with generally accepted accounting principles in the U.S., or U.S. 
GAAP. The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the 
reported amounts of assets and liabilities and the revenue and expenses incurred during the reported periods. We base estimates on our 
historical experience, known trends and various other factors that we believe are reasonable under the circumstances, the results of 
which form the basis for making judgments about the carrying value of assets and liabilities that are not apparent from other sources. 
Actual results may differ from these estimates under different assumptions or conditions. 

The significant accounting policies that we believe to be most critical in fully understanding and evaluating our financial results 

are revenue recognition, research and development costs and stock-based compensation. See “Note 3” of the consolidated financial 
statements for additional information.

Revenue recognition:  

Revenue recognition is a critical accounting estimate due to the magnitude and nature of the revenues we receive.  

We are eligible to receive non-refundable upfront payments, funding for research and development services, milestone 
payments, other contingent payments and royalties under our various collaboration agreements. In assessing the appropriate revenue 
recognition related to a collaboration agreement, we first determine whether an arrangement includes multiple elements, such as the 
delivery of intellectual property rights and research and development services. Revenues associated with multiple element 
arrangements are attributed to the various elements based on their relative fair values or are recognized as a single unit of accounting 
when relative fair values are not determinable.  

Non-refundable upfront payments are recorded as deferred revenue on the balance sheet and are recognized as collaboration 

revenue over the estimated period of research performance that is consistent with the terms of the research and development 
obligations contained in the collaboration agreement. We need to make estimates as to what period the services will be delivered as 
these payments are deferred and amortized into collaboration revenue over the estimated period of our ongoing involvement.  The 
actual period of our ongoing involvement may differ from the estimated period determined at the time the payment is initially received 
and recorded as deferred revenue.  This may result in a different amount of revenue that should have been recorded in the period and a 
longer or shorter period of revenue amortization. When an estimated period changes, we amortize the remaining deferred revenue over 
the estimated remaining time to completion.  

We  recognize  funding  related  to  full-time  equivalent  staffing  funded  through  collaboration  agreements  as  revenue on a 

gross basis as we perform or deliver such related services in accordance with the agreement terms, provided  that we will receive 
payment for such services upon standard payment terms. 

We recognize revenue contingent upon our achievement of a milestone in its entirety, in the period the milestone is achieved, 
only if the milestone meets certain criteria and is considered to be substantive. Payments received upon the occurrence of milestones 
that are non-substantive are deferred and recognized as revenue over the estimated period of performance applicable to the associated 
collaborative agreement. 

Research and development costs:  

Research and development costs is a critical accounting estimate due to the magnitude of and the many assumptions that are 

required to calculate third-party accrued and prepaid research and development expenses.  

We incur development activity costs, such as preclinical costs, manufacturing costs and clinical trial costs paid to contract 
research organizations, investigators and other vendors who conduct certain product development activities on our behalf. The amount 
of expenses recognized in a period related to service agreements is based on estimates of the work performed using an accrual basis of 
accounting. These estimates are based on patient enrollment, services provided and goods delivered, contractual terms and experience 
with similar contracts. We monitor these factors and adjust our estimates accordingly.  

Stock-based compensation:  

Stock-based compensation is a critical accounting estimate due to the magnitude of and the many assumptions that are required 

to calculate stock-based compensation expense. 

We grant stock options to employees, directors and officers pursuant to our stock option plan. Compensation expense is 

recorded using the fair value method. We calculate the fair value of stock options using the Black-Scholes option-pricing model which 
requires that certain assumptions, including the expected life of the option and expected volatility of the stock, be estimated at the time 
that the options are granted. 

Prior to our initial public offering, or IPO, our shares did not have a readily available market; therefore, we lack company-
specific historical and implied volatility information. Consequently, we estimated the expected volatility of our stock options based on 
a historical volatility analysis of peers that are similar with respect to industry, stage of development, size, and financial leverage. The 
expected term of our stock options has been determined utilizing the “simplified” method. Under this method, the expected term 
represents the average of the vesting period and the contractual term. We amortize the fair value of stock options using the straight-
line method over the vesting period of the options.

Revenue 

We recognized revenue of $1.8 million for the year ended December 31, 2016, compared to $15.6 million for the year ended 

December 31, 2015, a decrease of $13.8 million. In 2015, we recognized revenues relating to the upfront payment from our 
collaborative agreement with Teva which was fully recognized by December 2015 as well as revenue related to the upfront payment 
from our March 2014 collaborative agreement with Genentech which was fully recognized by March 2016. The remaining decrease 
was due to less full-time equivalent, or FTE, funding from Genentech as we shifted resources from supporting our collaborations to 
our proprietary programs.

Research and development expenses were $19.8 million for the year ended December 31, 2016, compared to $15.2 million for the 

year ended December 31, 2015. The increase of $4.7 million was primarily attributable to increased spending on our preclinical and 
discovery programs, mostly related to our Nav1.6 sodium channel inhibitor program, as well as additional expenses for our XEN801 
program which entered Phase 2 clinical development in February 2016. These increases were partially offset by a decrease in Genentech 
collaboration expenses.

year ended December 31, 2015, a decrease of $3.0 million. During 2015, we recognized a $1.7 million expense due to a fair value 
adjustment upon the reclassification of stock option awards granted to directors and certain consultants to liability classification. The 
remaining change is due to one-time severance costs resulting from an internal reorganization and acceleration of stock-based 
compensation expense for certain consultants that occurred in 2015.

largely from the translation of cash and cash equivalents and marketable securities denominated in Canadian dollars to U.S. dollars. 
We recorded a foreign exchange gain of $1.3 million in 2016, compared to a $6.9 million foreign exchange loss in 2015, largely due 
to a 3% increase as compared to a 16% decrease in the value of the Canadian dollar for the years ended December 31, 2016 and 2015, 
respectively.

We recognized revenue of $15.6 million for the year ended December 31, 2015, compared to $28.4 million for the year ended 
December 31, 2014, a decrease of $12.8 million. In 2014, we recognized a $7.9 million milestone payment from Genentech for the 
approval of the GDC-0276 Clinical Trial Application by Health Canada as well as revenue related to the upfront payment from the 
December 2011 collaborative development and license agreement with Genentech which was fully recognized by December 2014. 
The remaining decrease was due to less FTE funding from Genentech and Teva and the change in the foreign exchange rate between 
the U.S. and Canadian dollar.

adjustment upon the reclassification of stock option awards granted to directors and certain consultants to liability classification in the 
first quarter of 2015 and the subsequent change in fair value until the options were reclassified back to equity in the third quarter of 
2015. The remaining change is due to additional expenses incurred as a public company, including costs of additional personnel, 
additional professional fees for audit, accounting and legal services, director fees, enhanced business and accounting systems, costs 
related to investor relations and increased premiums for directors’ and officers’ liability insurance as well as one-time severance costs 
resulting from an internal reorganization and acceleration of stock-based compensation expense for certain consultants, partially offset

a foreign exchange loss of $6.9 million in 2015, arising largely from the translation of cash and cash equivalents denominated in 
Canadian dollars to U.S. dollars and a 16% decrease in the value of the Canadian dollar during the year. We recorded a foreign 
exchange gain of $1.3 million in 2014 prior to our functional currency change, arising largely from the translation of cash and cash 
equivalents denominated in U.S. dollars to Canadian dollars and a 9% increase in the value of the U.S. dollar during the year.

Liquidity and Capital Resources 

To date, we have financed our operations primarily through funding received from collaboration and license agreements, private 

placements of our common and preferred shares and public offerings of our common shares as well as through the receipt of 
government funding. As of December 31, 2016, we had cash and cash equivalents and marketable securities of $64.1 million. In 
September 2016, we completed an underwritten public offering of 3,450,000 of our common shares at a public offering price of $7.50 
per common share. We received approximately $24.3 million of proceeds, net of underwriting discounts and commissions but before 
offering expenses.  

We have incurred significant operating losses since inception. We had a $23.0 million net loss for the year ended December 31, 

2016 and an accumulated deficit of $142.7 million from inception through December 31, 2016. We expect to continue to incur 
significant expenses in excess of our revenue and expect to incur operating losses over the next several years. Our net losses may 
fluctuate significantly from quarter to quarter and year to year. We expect to continue to incur significant expenses and operating 
losses for the foreseeable future as we continue our research and preclinical and clinical development of our product candidates; 
expand the scope of our current studies for our product candidates; initiate additional preclinical, clinical or other studies for our 
product candidates, including under our collaboration agreements; change or add additional manufacturers or suppliers; seek 
regulatory and marketing approvals for any of our product candidates that successfully complete clinical studies; seek to identify and 
validate additional product candidates; acquire or in-license other product candidates and technologies; make milestone or other 
payments under our in-license agreements including, without limitation, our agreements with the University of British Columbia, or 
UBC, and the Memorial University of Newfoundland, or MUN; maintain, protect and expand our intellectual property portfolio; 
attract and retain skilled personnel; establish a sales, marketing and distribution infrastructure to commercialize any products for 
which we or one of our collaborators may obtain marketing approval, and maintain commercial rights; create additional infrastructure 
to support our operations and our product development and planned future commercialization efforts; and experience any delays or 
encounter issues with any of the above. 

Until such time as we can generate substantial product revenue, if ever, we expect to finance our cash needs through a 

combination of collaboration agreements and equity or debt financings. Except for any obligations of our collaborators to reimburse us 
for research and development expenses or to make milestone payments under our agreements with them, we do not have any 
committed external sources of capital. To the extent that we raise additional capital through the future sale of equity or debt, the 
ownership interest of our shareholders will be diluted, and the terms of these securities may include liquidation or other preferences 
that adversely affect the rights of our existing common shareholders. If we raise additional funds through collaboration agreements in 
the future, we may have to relinquish valuable rights to our technologies, future revenue streams or product candidates or grant 
licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when 
needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant 
rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. 

Our future capital requirements are difficult to forecast and will depend on many factors, including:

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

(cid:120) 

the number and characteristics of the future product candidates we pursue either from our internal research efforts or 
through acquiring or in-licensing other product candidates or technologies; 

the scope, progress, results and costs of independently researching and developing any of our future product candidates, 
including conducting preclinical research and clinical trials;  

whether our existing collaborations continue to generate substantial milestone payments and, ultimately, royalties on 
future approved products for us; 

the timing of, and the costs involved in, obtaining regulatory approvals for any future product candidates we develop 
independently; 

the cost of future commercialization activities, if any, including activities required pursuant to our option to co-promote 
TV-45070, if exercised by us, and the cost of commercializing any future products we develop independently that are 
approved for sale; 

the cost of manufacturing our future product candidates and products, if any; 

our ability to maintain existing collaborations and to establish new collaborations, licensing or other arrangements and the 
financial terms of such arrangements; 

77 

 
(cid:120) 

(cid:120) 

the costs of preparing, filing, prosecuting, maintaining, defending and enforcing patents, including litigation costs and the 
outcome of such litigation; and 

the timing, receipt and amount of sales of, or royalties on, Glybera or our collaborators’ product candidates, and our future 
products, if any. 

Based on our research and development plans and our timing expectations related to the progress of our programs, we expect 

that our existing cash and cash equivalents and marketable securities as of the date of this report, and research funding that we expect 
to receive under our existing collaborations, will enable us to fund our operating expenses and capital expenditure requirements for at 
least the next 12 to 24 months. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital 
resources sooner than we expect. Additionally, the process of testing drug candidates in clinical trials is costly, and the timing of 
progress in these trials remains uncertain.

Operating Activities 

Net cash used in operating activities totaled $19.6 million in 2016, compared to $18.1 million in 2015. The change was 
primarily related to a $4.7 million increase in research and development expenses and a $2.1 million decrease in FTE funding from 
Genentech in 2016, partially offset by a $3.2 million prepayment to Medpace, Inc., or Medpace, in 2015 for future clinical 
development services, a decrease in general and administrative expenses in 2016 and working capital changes.  

Net cash used in operating activities totaled $18.1 million in 2015, compared to $0.3 million of cash provided by operating 
activities for 2014. The change was primarily related to the increase in operating expenses in 2015, a $3.2 million prepayment to 
Medpace in 2015 for future clinical development services, a $7.9 million milestone payment recognized from Genentech in 2014, a 
$1.5 million upfront payment received from Genentech for the pain genetics collaboration entered into in March 2014 and $0.9 
million less FTE funding from Genentech and Teva in 2015 as compared to 2014. 

Investing Activities 

Net cash used in investing activities totaled $47.8 million in 2016, compared to $10.2 million of cash provided by investing 
activities in 2015. The change was driven primarily by the purchase of marketable securities during 2016 compared to the redemption 
of marketable securities during 2015. 

Net cash provided by investing activities totaled $10.2 million in 2015, compared to $3.2 million of cash used in investing 
activities for 2014. The change was driven primarily by the redemption of marketable securities in 2015 compared to a net investment 
in marketable securities in 2014 as well as a decrease in the purchase of property, plant and equipment as compared to 2014. 

Financing Activities 

Net cash provided by financing activities totaled $24.0 million in 2016, compared to $0.3 million in 2015. The change was 
primarily related to $23.8 million of net proceeds from the issuance of common shares in an underwritten public offering completed in 
September 2016. 

Net cash provided by financing activities totaled $0.3 million in 2015, compared to $41.1 million for 2014. Net cash provided 

by financing activities in 2015 consisted exclusively of proceeds from the issuance of common shares from the exercise of stock 
options whereas net cash provided by financing activities in 2014 was driven primarily by proceeds from the issuance of common 
shares related to our IPO and concurrent private placement in November 2014.

Burnaby, British Columbia, Canada. 

The contractual obligations table above excludes a priority access agreement entered into in August 2015 with Medpace for the 

provision of certain clinical development services. Under the terms of the agreement, we committed to using Medpace non-
exclusively for clinical development services over the five year term of the agreement.  In consideration for priority access to 
Medpace resources and preferred service rates, we committed to $7.0 million of services over the term of the agreement, $1.7 million 
of which was prepaid upon signing of the agreement and an additional $1.3 million was paid in December 2015. Any portion of the 
$3.0 million payment made during 2015 that is not used within the first three years of the agreement term will be forfeited to Medpace. 
If we do not meet the commitment to retain Medpace for $7.0 million of services during the term of the agreement, we agreed to give 
Medpace the exclusive right to perform all of our subsequent outsourced clinical development work until such $7.0 million commitment 
has been satisfied, subject to the availability of appropriate Medpace resources and reasonable service rates. If we decide not to retain 
Medpace for the provision of clinical development services, we may satisfy our obligations under the priority access agreement by 
paying Medpace an amount equal to half of the unsatisfied portion of the $7.0 million minimum commitment. See “Note 10(b)” and 
“Note 12” of the consolidated financial statements for additional information. 

Also excluded from the table above are potential future payments we may be required to make if we elect to opt into the co-

development arrangement under our collaboration with Merck or the co-promotion for TV-45070 under our collaboration with Teva. 
Our potential payment obligations in the single-digit percentage range to UBC related to amounts we receive from sales of Glybera are 
also excluded from the table. Additionally, the table does not include our potential royalty and milestone payment obligations to MUN 
pursuant to the Restated Collaborative Research & License Agreement by and between us and MUN dated December 2006. Pursuant 
to this agreement, we are obligated to pay MUN certain milestone payments and a single-digit percentage royalty of net sales for 
products that we sell directly and a single-digit percentage of royalties we receive from sales on products under our pain program. 

Inflation 

We do not believe that inflation has had a material effect on our business, financial condition or results of operations in the last 

three fiscal years. 

Off-Balance Sheet Arrangements 

We do not engage in any off-balance sheet financing activities. We do not have any interest in entities referred to as variable 

interest entities, which include special purposes entities and other structured finance entities. 

Related Party Transactions 

For a description of our related party transactions, see “Certain Relationships and Related Transactions, and Director 

Independence.” 

Outstanding Share Data 

As of March 3, 2017, we had 17,935,982 common shares issued and outstanding and outstanding stock options to purchase an 

additional 1,903,761 common shares.

Recent Accounting Pronouncements  

In May 2014, the Financial Accounting Standards Board, or FASB, issued amendments to clarify the principles of recognizing 
revenue and to develop a common revenue standard that would remove inconsistencies in revenue requirements, leading to improved 
comparability of revenue recognition practices across entities and industries. The amendments stipulate that an entity should recognize 
revenue to depict 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. Additional disclosure will also be required about the nature, 
amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and 
changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. In August 2015, the FASB issued an 
update deferring the effective date of the new revenue standard by one year. The new guidance will be effective for public entities for 
fiscal years and interim periods within those years, beginning after December 15, 2017 instead of the originally contemplated effective 
date of December 15, 2016.  

In March, April and May 2016, the FASB issued amendments to the new revenue standard to clarify the implementation 
guidance on principal versus agent considerations and identifying performance obligations and licensing as well as to address certain 
narrow-scope improvements and practical expedients at transition with the same effective date as the new revenue standard. We are 
currently evaluating the new guidance to determine the impact it will have on our consolidated financial statements. 

In February 2016, the FASB issued amendments to lease accounting requiring the recognition of lease assets and lease liabilities 

by lessees for those leases classified as operating leases under previous U.S. GAAP. The new guidance retains a distinction between 
finance leases and operating leases, with cash payments from operating leases classified within operating activities in the statement of 
cash flows. These amendments will be effective for public entities for fiscal years and interim periods within those years, beginning 
after December 15, 2018. We are currently evaluating the new guidance to determine the impact it will have on our consolidated 
financial statements. 

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk 

We are exposed to various market risks in the ordinary course of our business, including changes in interest rates and currency 

exchange rates. Market risk is the potential loss arising from adverse changes in interest rates and exchange rates. 

Foreign Currency Exchange Risk 

On January 1, 2015, our functional currency changed from the Canadian dollar to the U.S. dollar based on our analysis of the 

changes in the primary economic environment in which we operate. 

The principal market risk we face is foreign currency exchange rate risk. We face this risk, in part, as a result of entering into 

transactions denominated in currencies other than U.S. dollars, particularly those denominated in Canadian dollars. We also hold non-
U.S. dollar denominated cash and cash equivalents, marketable securities, accounts receivable and accounts payable, which are 
denominated in Canadian dollars. 

Changes in foreign currency exchange rates can create significant foreign exchange gains or losses to us. Our current foreign 
currency risk is with the Canadian dollar, as a majority of our non-U.S. dollar denominated expenses are denominated in Canadian 
dollars and the majority of our cash and cash equivalents and marketable securities are held in Canadian dollars. To limit our exposure 
to volatility in currency markets, we estimate our anticipated expenses that will be denominated in Canadian and U.S. dollars and then 
purchase a corresponding amount of Canadian or U.S. dollars at the current spot rate. Once these estimated expense amounts are 
acquired, we do not hedge our exposure and thus assume the risk of future gains or losses on the amounts of Canadian dollars held. At 
December 31, 2016, we held cash and cash equivalents and marketable securities of $28.3 million denominated in Canadian dollars. A 
hypothetical 10% increase (decrease) in the value of the Canadian dollar would result in a foreign exchange gain (loss) of $2.8 million 
being recorded in the Statement of Operations and Comprehensive Income (Loss) on the translation of these Canadian dollar cash and 
cash equivalent and marketable securities balances into the U.S. dollar functional currency. 

80 

 
 
 
Interest Rate Risk 

An additional market risk we face is interest rate risk. We had cash and cash equivalents and marketable securities of 

$64.1 million as of December 31, 2016. The goals of our investment policy are liquidity and capital preservation; we do not enter into 
investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate 
exposure. We believe that we do not have any material exposure to changes in the fair value of these assets as a result of changes in 
interest rates due to the short term nature of our cash and cash equivalents and marketable securities. Declines in interest rates, 
however, would reduce future investment income. A 10% change in interest rates during any of the periods presented would not have 
had a material impact on our consolidated financial statements. Such interest-earning instruments carry a degree of interest rate risk. 
We had no outstanding debt as of December 31, 2016.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Shareholders and Directors of Xenon Pharmaceuticals Inc. 

We have audited the accompanying consolidated balance sheets of Xenon Pharmaceuticals Inc. as of December 31, 2016 and 
December 31, 2015 and the related consolidated statements of operations and comprehensive income (loss), shareholders’ equity 
(deficit) and cash flows for each of the years in the three-year period ended December 31, 2016. These consolidated financial 
statements are the responsibility of Xenon Pharmaceuticals Inc.’s management. Our responsibility is to express an opinion on these 
financial statements 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 consolidated financial 
statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and 
disclosures in the consolidated 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 consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial 
position of Xenon Pharmaceuticals Inc. as of December 31, 2016 and December 31, 2015, and its consolidated results of operations 
and its consolidated cash flows for each of the years in the three-year period ended December 31, 2016 in conformity with US 
generally accepted accounting principles.

XENON PHARMACEUTICALS INC. 
Notes to Consolidated Financial Statements 
(Expressed in thousands of U.S. dollars except share and per share amounts) 

1. 

Nature of the business:  

Xenon Pharmaceuticals Inc. (the “Company”), incorporated in 1996 under the British Columbia Business Corporations Act and 
continued  federally  in  2000  under  the  Canada  Business  Corporation  Act,  is  a  clinical-stage  biopharmaceutical  company 
discovering and developing a pipeline of differentiated therapeutics for orphan indications that it intends to commercialize on its 
own, and for larger market indications that it intends to partner with global pharmaceutical companies. 

2. 

Basis of presentation:  

These consolidated financial statements are presented in U.S. dollars.  

The  accompanying  audited  consolidated  financial  statements  of  the  Company  have  been  prepared  in  accordance  with  United 
States generally accepted accounting principles (“U.S. GAAP”). 

The  Company  has  one  wholly-owned  subsidiary  as  at  December  31,  2016,  Xenon  Pharmaceuticals  USA  Inc.  which  was 
incorporated in Delaware on December 2, 2016. 

These  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its  wholly-owned  subsidiary.  All 
intercompany transactions and balances have been eliminated on consolidation.  

3. 

Significant accounting policies:  

(a)  Use of estimates:  

The  preparation  of  the  consolidated  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make 
estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and 
liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting 
period. Significant areas of estimates include, but are not limited to, the timing of revenue recognition, the determination 
of stock-based compensation and the amounts recorded as accrued liabilities. Actual results could differ materially from 
those estimates. Estimates and assumptions are reviewed quarterly. All revisions to accounting estimates are recognized in 
the period in which the estimates are revised and in any future periods affected.  

(b)  Cash and cash equivalents:  

Cash  equivalents  are  highly  liquid  investments  that  are  readily  convertible  into  cash  with  terms  to  maturity  of  three 
months  or  less  when  acquired.  Cash  equivalents  are  recorded  at  cost  plus  accrued  interest.  The  carrying  value  of  these 
cash equivalents approximates their fair value.  

(c)  Marketable securities:  

Marketable securities are investments with original maturities exceeding three months, and have remaining maturities of 
less than one year. Marketable securities accrue interest based on a fixed interest rate for the term. The carrying value of 
marketable securities is recorded at cost plus accrued interest, which approximates their fair value. 

(d) 

Intellectual Property 

The costs incurred in establishing and maintaining patents for intellectual property developed internally are expensed in 
the period incurred. 

(e)  Property, plant and equipment:  

Property, plant and equipment are stated at cost less accumulated depreciation and/or accumulated impairment losses, if 
any. Repairs and maintenance costs are expensed in the period incurred.  

88 

 
 
 
 
 
 
Property, plant and equipment are amortized over their estimated useful lives using the straight-line method based on the 
following rates:  

Asset 
Research equipment 
Office furniture and equipment 
Computer equipment 
Leasehold improvements 

Rate 
5 years 
5 years 
3 years 
Over the lesser of lease term or 
estimated useful life 

(f) 

Impairment of long-lived assets:  

The  Company  monitors  its  long-lived  assets  for  indicators  of  impairment.  If  such  indicators  are  present,  the  Company 
assesses the recoverability of affected assets by determining whether the carrying value of such assets is less than the sum 
of the undiscounted future cash flows of the assets. If such assets are found not to be recoverable, the Company measures 
the amount of such impairment by comparing the carrying value of the assets to the fair value of the assets, with the fair 
value  generally determined based on the present  value of the expected  future cash  flows associated  with the assets. No 
impairment of long-lived assets was noted during the years ended December 31, 2016 and 2015.  

(g)  Concentration of credit risk and of significant customers:  

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of 
cash  and  cash  equivalents.  Cash  and  cash  equivalents  were  held  at  two  major  financial  institutions  in  Canada.  Such 
deposits may be in excess of insured limits in the event of non-performance by the institutions; however, the Company 
does not anticipate non-performance. 

Collaborators whose collaboration research and development revenue accounted for 10% or more of total revenues were 
as follows:

(h)  Financial instruments and fair value:  

We measure certain financial instruments and other items at fair value.  

To determine the fair value, we use the fair value hierarchy for inputs used to measure fair value of financial assets and 
liabilities. This hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three levels: Level 1 
(highest priority), Level 2, and Level 3 (lowest priority).  

(cid:120) 

(cid:120) 

(cid:120) 

Level 1 - Unadjusted quoted prices in active markets for identical instruments. 

Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either 
directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted 
prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that 
are observable for the asset or liability (i.e., interest rates, yield curves, etc.), and inputs that are derived principally 
from or corroborated by observable market data by correlation or other means (market corroborated inputs).  

Level 3 - Inputs are unobservable and reflect the Company’s assumptions as to what market participants would use 
in pricing the asset or liability. The Company develops these inputs based on the best information available.  

Assets and liabilities are classified based on the lowest level of input that is significant  to the fair value  measurements. 
Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the 
fair value hierarchy. 

The Company’s Level 1 assets include cash and cash equivalents and marketable securities with quoted prices in active 
markets.  The  carrying  amount  of  accounts  receivables,  accounts  payable  and  accrued  expenses  approximates  fair  value 
due to the  nature and  short-term of those instruments.  As  quoted prices for the  liability classified stock options are  not 
readily  available,  the  Company  has  used  a  Black-Scholes  pricing  model  to  estimate  fair  value  using  Level  3  inputs  as 
defined above.

(i)  Revenue recognition:  

The Company recognizes revenue  when all of the following criteria are  met: (i) persuasive evidence of an arrangement 
exists; (ii) delivery has occurred or services have been rendered; (iii) the Company’s price to the collaborator is fixed or 
determinable; and (iv) collectability is reasonably assured.  

The Company generates revenue primarily through collaboration agreements.  

Under these collaboration agreements, the Company is eligible to receive non-refundable upfront payments, funding for 
research  and  development  services,  milestone  payments,  other  contingent  payments  and  royalties.  In  assessing  the 
appropriate  revenue  recognition  related  to  a  collaboration  agreement,  the  Company  first  determines  whether  an 
arrangement includes multiple elements, such as the delivery of intellectual property rights and research and development 
services.  Revenues  associated  with  multiple  element  arrangements  are  attributed  to  the  various  elements  based  on  their 
relative fair values or are recognized as a single unit of accounting when relative fair values are not determinable.  

Non-refundable  upfront  payments  are  recorded  as  deferred  revenue  on  the  balance  sheet  and  are  recognized  as 
collaboration revenue over the estimated period of research performance that is consistent with the terms of the research 
and development obligations contained in the collaboration agreement. The Company periodically reviews the estimated 
period of performance based on the progress made under each arrangement.  

The  Company  recognizes  funding  related  to  full-time  equivalent  staffing  funded  through  collaboration  agreements  as 
revenue on a gross basis as it performs or delivers such related services in accordance with the agreement terms, provided 
that it will receive payment for such services upon standard payment terms.  

The  Company  recognizes  revenue  contingent  upon  its  achievement  of  a  milestone  in  its  entirety,  in  the  period  the 
milestone is achieved, only if the milestone meets certain criteria and is considered to be substantive. Payments received 
upon  the  occurrence  of  milestones  that  are  non-substantive  are  deferred  and  recognized  as  revenue  over  the  estimated 
period of performance applicable to the associated collaborative agreement. 

(j)  Research and development costs:  

Research and development costs are expensed in the period incurred.  

Certain development activity costs, such as preclinical costs, manufacturing costs and clinical trial costs, are a component 
of  research  and  development  costs  and  include  fees  paid  to  contract  research  organizations,  investigators  and  other 
vendors  who  conduct  certain  product  development  activities  on  behalf  of  the  Company.  The  amount  of  expenses 
recognized in a period related to service agreements is based on estimates of the work performed using an accrual basis of 
accounting. These estimates are based on patient enrollment, services provided and goods delivered, contractual terms and 
experience with similar contracts. The Company monitors these factors and adjusts the estimates accordingly. Payments 
made to third parties under these arrangements in advance of the receipt of the related services are recorded as prepaid 
expenses until the services are rendered.  

(k)  Stock-based compensation:  

The Company grants stock options to employees, directors and officers pursuant to a stock option plan described in note 
7c. 

Employee stock-based compensation expense is measured at the grant date, based on the estimated fair value of the award, 
and is recognized as an expense, net of actual forfeitures, over the requisite service period with a corresponding increase 
in  additional  paid-in  capital.  Stock-based  compensation  expense  is  amortized  on  a  straight-line  basis  over  the  requisite 
service  period  for  the  entire  award,  which  is  generally  the  vesting  period  of  the  award.  Any  consideration  received  on 
exercise of stock options is credited to share capital. 

(l) 

Liability classified stock options: 

Stock  option  awards  accounted  for  under  Accounting  Standards  Codification  (“ASC”)  718  -  Compensation  -  Stock 
Options (“ASC 718”) that provide for an exercise price that is not denominated in: (a) the currency of the market in which 
a  substantial  portion  of  the  Company’s  equity  securities  trades,  (b)  the  currency  in  which  the  optionee’s  pay  is 
denominated,  or  (c)  the  Company’s  functional  currency,  are  classified  as  liabilities.  Following  the  change  in  functional 
currency on January 1, 2015, described in (n) below, options granted to members of the Company’s board of directors and 
certain consultants with exercise prices denominated in Canadian dollars were subject to liability accounting, resulting in 
a reclassification of these awards from additional paid-in capital to liability classified stock options. 

90 

 
In  September  2015,  the  Company  modified  certain  compensation  arrangements  to  be  denominated  in  Canadian  dollars. 
Following this  modification,  options denominated in  Canadian dollars that  were  granted to  members of the  Company’s 
board of directors and certain consultants met the criteria for equity classification with fair value at the modification date 
calculated  using  the  Black-Scholes  option-pricing  model  and  reclassified  from  liability  classified  stock  options  back  to 
additional paid-in capital. The modified awards are accounted for as equity awards from the date of modification. 

Stock options awards accounted for under ASC 815 - Derivatives and Hedging (“ASC 815”), that provide for an exercise 
price which is not denominated in the Company’s functional currency are required to be classified as liabilities. Certain 
stock option awards with exercise prices denominated in Canadian dollars are accounted for under ASC 815 and classified 
as liabilities. As of December 31, 2016, such liability classified stock options totaled $261 (2015 - $nil) and are included 
in the consolidated balance sheet as accounts payable and accrued expenses. 

Liability  classified  stock  options  are  re-measured  at  fair  value  using  the  Black-Scholes  option-pricing  model  at  each 
balance sheet date until exercised or cancelled, with changes in fair value recognized as general and administrative stock-
based compensation expense or additional paid-in capital for ASC 718 awards or general and administrative stock-based 
compensation expense for ASC 815 awards for the period. The Black-Scholes option pricing model uses various inputs to 
measure  fair  value,  including  fair  value  of  the  Company’s  underlying  common  shares  at  the  grant  date,  expected  term, 
expected volatility, risk-free interest rate and expected dividend yield of the Company’s common shares.  

(m)  Net income (loss) per common share: 

Basic net income (loss) per common share is computed by dividing the net income (loss) by the weighted average number 
of common shares outstanding for the period. Diluted net income (loss) per common share is computed by adjusting the 
numerator  and  denominator  of  the  basic  net  income  (loss)  per  share  calculation  for  the  potential  impact  of  dilutive 
securities. 

For the years ended December 31, 2016 and December 31, 2015, all stock options were anti-dilutive and were excluded 
from the diluted weighted average common shares outstanding for those periods. For the year ended December 31, 2014, 
154,057  stock options were excluded from the calculation of net income per common share because their inclusion would 
be anti-dilutive. 

(n)  Foreign currency translation:  

The Company’s reporting currency is the U.S. dollar. The functional currency of the Company changed to U.S. dollars 
from  Canadian  dollars  on  January  1,  2015  based  on  management’s  analysis  of  the  changes  in  the  primary  economic 
environment  in  which  the  Company  operates.  The  Company’s  reporting  currency  did  not  change.  The  change  in 
functional currency is accounted for prospectively from January 1, 2015 and prior year financial statements have not been 
restated for the change in functional currency. 

For  all  relevant  periods,  foreign  currency  revenue  and  expense  transactions  were  recorded  using  the  exchange  rates 
prevailing at the dates of the transactions. 

For periods prior to January 1, 2015, the effects of exchange rate fluctuations on translating foreign currency  monetary 
assets and liabilities into Canadian dollars were included in the statement of operations and comprehensive income (loss) 
as foreign exchange gain (loss). Revenue and expense transactions were translated into the U.S. dollar reporting currency 
at the balance sheet date at average exchange rates during the period, and assets and liabilities were translated at end of 
period exchange rates, except for equity transactions, which were translated at historical exchange rates. Translation gains 
and losses from the application of the U.S. dollar as the reporting currency while the Canadian dollar was the functional 
currency are included as part of the cumulative foreign currency translation adjustment, which is reported as a component 
of shareholders’ equity under accumulated other comprehensive income (loss). 

For periods commencing January 1, 2015, monetary assets and liabilities denominated in foreign currencies are translated 
into U.S. dollars using exchange rates in effect at the balance sheet date. Opening balances related to non-monetary assets 
and liabilities are based on prior period translated amounts, and nonmonetary assets and nonmonetary liabilities incurred 
after January 1, 2015 are translated at the approximate exchange rate prevailing at the date of the transaction. Revenue and 
expense  transactions  are  translated  at  the  approximate  exchange  rate  in  effect  at  the  time  of  the  transaction.  Foreign 
exchange gains and losses are included in the consolidated statement of operations and comprehensive income (loss) as 
foreign exchange gain (loss). 

91 

 
(o) 

Income taxes:  

Deferred  income  taxes  are  recognized  for  the  future  tax  consequences  attributable  to  differences  between  the  carrying 
amounts of assets and liabilities and their respective tax bases and net operating loss and credit carryforwards. Deferred 
income tax assets and liabilities are measured at enacted rates expected to apply to taxable income in the years in which 
those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred income tax 
assets and liabilities of a change in tax rates is recognized in the consolidated statement of operations and comprehensive 
income  (loss)  in  the  period  that  includes  the  enactment  date.  A  valuation  allowance  is  provided  when  realization  of 
deferred income tax assets does not meet the more-likely-than-not criterion for recognition. 

(p)  Deferred tenant inducements:  

Deferred tenant inducements, which include leasehold improvements paid for by the landlord and free rent, are recorded 
as liabilities on the balance sheet and recognized as a reduction of rent expense on a straight-line basis over the term of the 
lease. 

(q)  Segment and geographic information:  

Operating segments are defined as components of an enterprise about which separate discrete information is available for 
evaluation by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in 
assessing performance. The Company views its operations and manages its business in one operating segment. 

(r)  Comparative figures: 

Certain comparative figures have been reclassified to conform to the consolidated financial statement presentation adopted 
for the current year. 

4. 

Future changes in accounting policies:  

In May 2014, the Financial Accounting Standards Board (“FASB”) issued amendments to clarify the principles of recognizing 
revenue and to develop a common revenue standard that would remove inconsistencies in revenue requirements, leading to 
improved comparability of revenue recognition practices across entities and industries. The amendments stipulate that an entity 
should recognize revenue to depict 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. Additional disclosure will also 
be required about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, 
including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a 
contract. In August 2015, the FASB issued an update deferring the effective date of the new revenue standard by one year. The 
new guidance will be effective for public entities for fiscal years and interim periods within those years, beginning after 
December 15, 2017 instead of the originally contemplated effective date of December 15, 2016.  

In March, April and May 2016, the FASB issued amendments to the new revenue standard to clarify the implementation 
guidance on principal versus agent considerations and identifying performance obligations and licensing as well as to address 
certain narrow-scope improvements and practical expedients at transition with the same effective date as the new revenue 
standard. The Company is currently evaluating the new guidance to determine the impact it will have on the Company’s 
consolidated financial statements. 

In February 2016, the FASB issued amendments to lease accounting requiring the recognition of lease assets and lease liabilities 
by lessees for those leases classified as operating leases under previous U.S. GAAP. The new guidance retains a distinction 
between finance leases and operating leases, with cash payments from operating leases classified within operating activities in 
the statement of cash flows. These amendments will be effective for public entities for fiscal years and interim periods within 
those years, beginning after December 15, 2018. The Company is currently evaluating the new guidance to determine the impact 
it will have on the Company’s consolidated financial statements.

On November 10, 2014, the Company completed an initial public offering (“IPO”) of 4,600,000 of its common shares at a 
purchase price of $9.00 per common share. On November 10, 2014, the Company also completed a private placement, in 
which the Company issued 495,000 of its common shares to an affiliate of Genentech, a member of the Roche Group, at a 
price of $9.00 per common share. The Company received  $38.5 million of proceeds, net of underwriting discounts and 
commissions but before offering expenses, from the IPO and $4.1 million of proceeds, net of underwriters’ fees but before 
offering expenses, from the concurrent private placement.  

Immediately prior to the closing of the IPO, all outstanding Series A and B redeemable convertible preferred shares were 
converted into common shares on a 1:1 basis and Series E redeemable convertible preferred shares were converted into 
common shares on a 1:1.2 basis, subject to certain adjustments. These adjustments differed for some of the Company’s 
outstanding Series E preferred shares depending on the date of issue, resulting in different conversion ratios for different 
Series E preferred shares. All outstanding convertible preferred shares were converted into 7,725,924 common shares and 
10,201  outstanding  subscription  rights  were  converted  into  10,201  common  shares.  Following  the  IPO,  there  were  no 
preferred shares or subscription rights outstanding. 

On September 13, 2016, the Company completed an underwritten public offering of 3,450,000 of its common shares at a 
public offering price of $7.50 per common share. The Company received approximately $24.3 million of proceeds, net of 
underwriting discounts and commissions but before offering expenses. 

(b)  Authorized share capital: 

Immediately prior to the closing of the Company’s IPO, all outstanding Series  A, B, C, D and E preferred shares  were 
converted into common shares.  

Post  IPO,  the  Company’s  authorized  share  capital  consists  of  an  unlimited  number  of  common  and  preferred  shares 
without par value.

(c)  Stock-based compensation: 

On June 25, 2014, the shareholders of the Company approved the 2014 Equity Incentive Plan (the “2014 Plan”)  which 
permits the grant of stock-based compensation awards to directors, officers, employees and consultants of the Company. 
The  Company’s  pre-existing  stock  option  plan  (the  “Amended  and  Restated  Stock  Option  Plan”)  was  limited  to  the 
granting  of  stock  options  as  equity  incentive  awards  whereas  the  2014  Plan  also  allows  for  the  issuance  of  restricted 
shares, restricted share units, share appreciation rights and performance shares. The 2014 Plan replaced the Amended and 
Restated Stock Option Plan. No further options will be granted under the Company’s Amended and Restated Stock Option 
Plan. 

The Amended and  Restated Stock Option Plan provided for the grant of options  for the  purchase of common  shares to 
directors, officers, employees and consultants prior to the Company’s IPO. The options granted under the Amended and 
Restated Stock Option Plan vest on a graduated basis over a four-year period or less and each option’s maximum term is 
ten years. The Amended and Restated Stock Option Plan will continue to govern the options granted thereunder. 

Under the 2014 Plan, options granted generally vest on a graduated basis over a four-year period or less. The exercise price 
of the options is determined by the Board but must at least be equal to the fair market value of the common shares on the 
date of grant. Options may be exercised over a maximum term of ten years. As of December 31, 2016, a total of 65,132 
stock options remain to be granted under the 2014 Plan. The number of common shares available for issuance under the 
2014 Plan was increased by 500,000 in January 2017 as approved by the Board in accordance with the terms of the 2014 
Plan.

The aggregate  fair  value of options  vested during the  year ended December 31, 2016 was $3,220 (2015 - $999, 2014 - 
$722). 

The  fair  value  of  stock  options  at  the  date  of  grant  is  estimated  using  the  Black-Scholes  option-pricing  model  which 
requires multiple subjective inputs. The risk-free interest rate of the options is based on the U.S. Treasury yield curve in 
effect at the date of grant for a term similar to the expected term of the option. Prior to the IPO, the Company’s shares did 
not  have  a  readily  available  market;  therefore,  the  Company  lacks  company-specific  historical  and  implied  volatility 
information. Consequently, the expected volatility of stock options was estimated based on a historical volatility analysis 
of peers that were similar to the Company with respect to industry, stage of life cycle, size, and financial leverage. The 
expected term of the Company’s stock options has been determined utilizing the “simplified” method. Under this method, 
the expected term represents the average of the vesting period and the contractual term. The dividend yield is based on the 
fact that the Company has never paid cash dividends and has no present intention to pay cash dividends. Forfeitures are 
recognized as they occur.  

The weighted-average option pricing assumptions are as follows:  

Average risk-free interest rate 
Expected volatility 
Average expected term (in years)

Concentrations of market risk:  

(a)  Foreign currency risk:  

At December 31, 2016, the Company had U.S. dollar denominated cash and cash equivalents and marketable securities of 
$35,859 (December 31, 2015 - $17,836) and Canadian denominated cash and cash equivalents and marketable securities 
of CAD$37,980 (December 31, 2015 - CAD$56,491).  

The Company faces foreign currency exchange rate risk in part, as a result of entering into transactions denominated in 
currencies other than U.S. dollars, particularly those denominated in Canadian dollars. The Company also holds non-U.S. 
dollar denominated cash and cash equivalents, marketable securities, accounts receivable and accounts payable, which are 
denominated in Canadian dollars.  

Changes in foreign currency exchange rates can create significant foreign exchange gains or losses to the Company. The 
Company’s  current  foreign  currency  risk  is  with  the  Canadian  dollar,  as  a  majority  of  non-U.S.  dollar  denominated 
expenses are denominated in Canadian dollars and the majority of cash and cash equivalents and marketable securities are 
held  in  Canadian  dollars.  To  limit  the  Company’s  exposure  to  volatility  in  currency  markets,  management  estimates 
anticipated expenses that will be denominated in Canadian and U.S. dollars and then purchases a corresponding amount of 
Canadian or U.S. dollars at the current spot rate. Once these estimated expense amounts are acquired, the Company does 
not hedge its exposure and thus assumes the risk of future gains or losses on the amounts of Canadian dollars held.  

(b) 

Interest Rate Risk: 

At  December  31,  2016,  the  Company  had  cash  and  cash  equivalents  and  marketable  securities  of  $64,146.  The 
Company’s  interest  rate  risk  is  primarily  attributable  to  its  cash  and  cash  equivalents  and  marketable  securities.  The 
Company believes that it does not have any material exposure to changes in the fair value of these assets as a result of 
changes in interest rates due to the short term nature of cash and cash equivalents and marketable securities. The Company 
does not enter into investments for trading or speculative purposes and has not used any derivative financial instruments to 
manage interest rate exposure. A 10% change in interest rates during any of the periods presented would not have had a 
material  impact  on  the  Company’s  consolidated  financial  statements.  The  Company  had  no  outstanding  debt  as  of 
December 31, 2016. 

9. 

Collaboration agreements:  

The  Company  has  entered  into  a  number  of  collaboration  agreements  with  multiple  deliverables  under  which  it  may  have 
received non-refundable upfront payments. The Company generally recognizes revenue from non-refundable upfront payments 
ratably over the term of its estimated period of performance of research under its collaboration agreements in the event that such 
arrangements represent a single unit of accounting.  

The collaborations may also include contractual milestone payments, which relate to the achievement of pre-specified research, 
development,  regulatory  and  commercialization  events.  The  milestone  events  coincide  with  the  progression  of  product 
candidates  from  research  and  development,  to  regulatory  approval  and  through  to  commercialization.  The  process  of 
successfully discovering a new product candidate, having it selected by the collaborator for development and having it approved 
and  ultimately  sold  for  a  profit  is  highly  uncertain.  As  such,  the  milestone  payments  that  the  Company  may  earn  from  its 
collaborators involve a significant degree of risk to achieve.

Research and development milestones in the Company’s collaboration agreements may include the following types of events:  

(cid:120) 

(cid:120) 

(cid:120) 

completion of preclinical research and development work leading to selection of product candidates;  

initiation of Phase 1, Phase 2 or Phase 3 clinical trials; and  

achievement of certain other scientific or development events.  

Regulatory milestone payments may include the following types of events:  

(cid:120) 

(cid:120) 

filing of regulatory applications for marketing approval in the U.S., Europe or Japan, including investigational new drug 
(“IND”) applications and new drug applications (“NDA”); and  

marketing approval in a major market, such as the U.S., Europe or Japan.  

Commercialization  milestone  payments  may  include  payments  triggered  by  annual  product  sales  that  achieve  pre-specified 
thresholds.  

 (a)  Teva Pharmaceutical Industries Ltd. (“Teva”) collaborative development and license agreement:  

In December 2012, the Company entered into a collaborative development and license agreement with Teva, through its 
subsidiary,  Ivax  International  GmbH,  pursuant  to  which  the  Company  granted  Teva  an  exclusive  worldwide  license  to 
develop and commercialize certain products, including TV-45070 (formerly XEN402).  

Under the terms of the agreement, Teva paid the Company an upfront fee of $41,000. The Company is collaborating with 
Teva to further develop TV-45070, and Teva is funding all development costs with respect to the licensed products. Teva 
is providing funding to the Company for certain of the Company’s full-time equivalents (“FTEs”) performing the research 
collaboration  plan.  The  Company  identified  several  deliverables  under  the  agreement  with  Teva,  including  exclusive 
licenses  to  compounds  and  non-exclusive  licenses  to  companion  diagnostic  products,  a  commitment  to  participate  in  a 
joint steering committee and research and development services to be performed by the Company on behalf of Teva. The 
Company concluded that the licenses did not have stand-alone value to Teva without the Company’s technical expertise 
and joint steering committee participation during the initial three-year period.  

Therefore, the Company has determined that the various deliverables under this agreement should be considered as one 
single  unit of accounting.  As  such the Company determined that the $41,000 upfront payment  should be recognized as 
revenue ratably over the expected period of performance, being the three-year period ended December 31, 2015.  

In  addition,  the  Company  is  eligible  to  receive  potential  milestone  payments  totaling  up  to  $335,000,  comprised  of  a 
$20,000  clinical  milestone  payment,  up  to  $285,000  in  regulatory  milestone  payments,  and  a  $30,000  sales-based 
milestone  payment.  If  TV-45070  is  approved,  the  Company  is  also  eligible  to  receive  royalties  in  the  low  teens  to  low 
twenties on net sales of licensed products for the timeframe that such products are covered by the licensed patents and in 
certain  other  instances.  The  Company  believes  that  potential  milestone  payments  for  development  and  regulatory 
milestones under this agreement are substantive and at risk at the inception of this agreement, and, as such, expects that 
these  future  milestone  payments  will  be  recognized  as  revenue  in  the  period  that  each  milestone  is  achieved.  The 
Company  believes  that  the  potential  sales-based  milestone  payments  under  this  agreement  are  not  substantive  as  the 
Company does not expect to contribute effort to their achievement and expects such sales-based milestones will generally 
be  achieved  after  the  period  of  substantial  involvement  under  the  collaboration.  Therefore,  the  Company  expects  that 
future sales-based contingent consideration milestone payments will be recognized as revenue when such milestones are 
achieved,  assuming  all  other  revenue  recognition  criteria  are  met.  To  date,  no  such  milestone  payments  have  been 
recognized.  

Pursuant to the terms of the Company’s agreement with the Memorial University of Newfoundland, the Company must 
pay to the Memorial University of Newfoundland certain  milestone payments, a single-digit percentage of net  sales  for 
pain products the Company sells directly and a single-digit percentage of royalties received for sales of pain products by 
the Company’s third party licensees, such as under the Teva and Genentech agreements.  

(b)  Genentech collaborative research and license agreement:  

In  December  2011,  the  Company  entered  into  a  collaborative  research  and  license  agreement  with  Genentech  and  its 
affiliate, F. Hoffman-La Roche Ltd. (“Roche”) to discover and develop small and large molecules that selectively inhibit 
the Nav1.7 sodium channel and companion diagnostics for the potential treatment of pain. Pursuant to this agreement, the 
Company granted Genentech a worldwide exclusive license to develop and commercialize compounds directed to Nav1.7 
and  products  incorporating  such  compounds  for  all  uses.  The  Company  also  granted  Genentech  a  worldwide  non-
exclusive license to diagnostic products for the purpose of developing or commercializing such compounds.  

97 

 
Under the terms of the agreement, Genentech paid the Company an upfront fee of $10,000. Genentech provided funding 
to the Company for certain of the Company’s FTEs performing the research collaboration plan. The Company identified 
several deliverables under the agreement with Genentech, including exclusive licenses to compounds and non-exclusive 
licenses to diagnostic products, a commitment to participate in a joint steering committee and research and development 
services to be performed by the Company on behalf of Genentech. The Company concluded that the licenses did not have 
stand-alone  value  to  Genentech  without  the  Company’s  technical  expertise  and  joint  steering  committee  participation 
during  the  initial  three  year  period.  Therefore,  the  Company  has  determined  that  the  various  deliverables  should  be 
considered as a single unit of accounting. As such the Company determined that the $10,000 upfront payment should be 
recognized as revenue ratably over the expected period of performance, being the three-year period ended December 22, 
2014.  

The  Company  is  eligible  to  receive  pre-commercial  and  commercial  milestone  payments  with  respect  to  the  licensed 
products totaling up to an additional $613,000, comprised of up to $45,500 in preclinical and clinical milestone payments, 
up  to  $387,500  in  regulatory  milestone  payments,  and  up  to  $180,000  in  sales-based  milestone  payments  for  multiple 
products  and  indications.  In  addition,  the  Company  is  eligible  to  receive  royalties  based  on  net  sales  of  the  licensed 
products, which range from a mid single-digit percentage to ten percent for small-molecule inhibitors for the timeframe 
that such products are covered by the licensed patents and a low single-digit percentage thereafter until the date that is ten 
years  after  first  commercial  sale  on  a  country-by-country  basis,  plus  a  low  single-digit  percentage  for  large-molecule 
inhibitors  of  Nav1.7  for  a  period  of  ten  years  from  first  commercial  sale  on  a  country-by-country  basis.  The  Company 
believes that the potential milestone payments for preclinical, clinical and regulatory milestones under this agreement are 
substantive and at risk at inception of this agreement, and, as such, expects that these future milestone payments will be 
recognized as revenue in the period that each milestone is achieved. In the year ended December 31, 2016, no milestone 
payments have been recognized (2015 - $nil; 2014 - $8,000).  

The Company believes that the potential sales-based milestone payments under this agreement are not substantive as the 
Company does not expect to contribute effort to their achievement and expects such sales-based milestones will generally 
be  achieved  after  the  period  of  substantial  involvement  under  the  collaboration.  Therefore,  the  Company  expects  that 
future sales-based contingent consideration milestone payments will be recognized as revenue when such milestones are 
achieved,  assuming  all  other  revenue  recognition  criteria  are  met.  To  date,  no  such  milestone  payments  have  been 
recognized. 

In  March  2014,  the  Company  entered  into  a  new  agreement  with  Genentech  for  pain  genetics,  using  the  Company’s 
Extreme  Genetics  discovery  platform  to  focus  on  identifying  genetic  targets  associated  with  rare  phenotypes  where 
individuals  have  an  inability  to  perceive  pain  or  where  individuals  have  non-precipitated  spontaneous  severe  pain. 
Pursuant to the terms of this agreement, any intellectual property arising out of the collaboration will be jointly owned by 
the Company and Genentech. The Company also granted Genentech a time-limited, exclusive right of first negotiation on 
a target-by-target basis to form joint drug discovery collaborations. Under the terms of this agreement, Genentech paid an 
upfront payment of $1,500. The Company is eligible to receive additional milestone payments totaling up to $1,750. At 
the  option  of  the  Company,  a  Genentech  affiliate  invested  $4,455  in  a  private  placement  concurrent  with  the  IPO,  as 
described in note 7a.  

The  Company  identified  several  deliverables  under  this  agreement  with  Genentech,  including  non-exclusive  licenses  to 
certain  intellectual  property  controlled  by  the  Company,  a  commitment  to  participate  in  a  joint  steering  committee  and 
collaborative research services to be performed by the Company. The Company concluded that the licenses did not have 
stand-alone  value  to  Genentech  without  the  Company’s  technical  expertise  and  joint  steering  committee  participation 
during  the  initial  two  year  period.  Therefore,  the  Company  has  determined  that  the  various  deliverables  should  be 
considered as a single unit of accounting. As such the Company determined that the $1,500 upfront payment should be 
recognized as revenue ratably over the expected period of performance, being the two-year period ended March 18, 2016.  

The Company believes that the potential milestone payments under this agreement are substantive and at risk at inception 
of this agreement, and, as such, expects that these future milestone payments will be recognized as revenue in the period 
that  each  milestone  is  achieved.  In  the  year  ended  December  31,  2016,  no  milestone  payments  have  been  recognized 
(2015 - $250).

(c) 

uniQure Biopharma B.V. (“uniQure”) sublicense and research agreement:  

Effective  August  2000,  the  Company  entered  into  a  sublicense  and  research  agreement  with  uniQure  (formerly 
Amsterdam  Molecular  Therapeutics),  pursuant  to  which  the  Company  granted  to  uniQure  an  exclusive,  worldwide 
sublicense under certain intellectual property controlled by  the Company to develop and commercialize technology and 
compounds related to a certain variant of lipoprotein lipase (“LPL”). Under its sublicense and research agreement  with 
uniQure,  the  Company  collaborated  with  uniQure  and  the  University  of  British  Columbia  (“UBC”)  on  preclinical 
activities,  and  thereafter  uniQure  developed  an  LPL  gene  therapy  product,  Glybera,  which  contains  the  LPL  variant. 
Glybera was approved in the European Union (“EU”) in October 2012 to treat lipoprotein lipase deficiency (“LPLD”) in 
patients with severe or multiple pancreatitis attacks, despite dietary fat restrictions. uniQure conducted the clinical trials 
and is responsible for the commercialization of Glybera.  

Under the terms of the agreement, the Company is eligible to receive certain additional milestone payments of less than 
CAD$1,000 for Glybera and for each subsequent product, if any, developed pursuant to the agreement with uniQure. The 
Company,  in  turn,  has  certain  payment  obligations  to  its  licensor,  UBC,  based  on  amounts  received  from  uniQure  or 
otherwise  based  on  the  exploitation  of  the  licensed  intellectual  property.  The  Company  believes  that  all  potential 
milestone  payments  under  this  agreement  are  substantive  and  at  risk  at  the  inception  of  this  agreement,  and,  as  such, 
expects that  future  milestone  payments  will be recognized as revenue in the period that each  milestone is achieved. No 
milestone payments have been recognized in the years ended December 31, 2016, 2015 and 2014. 

The Company is also eligible to receive mid single-digit royalties on net sales of the licensed products, for sales made by 
uniQure and its affiliates. The royalty rates for sales made by uniQure and its affiliates are reduced to a low single-digit 
when the licensed patents expire.  

In  July  2013,  uniQure  announced  that  it  entered  into  a  partnership  with  Chiesi  Farmaceutici  S.p.A.  (“Chiesi”)  for  the 
commercialization of Glybera in the EU and more than a dozen other countries. With respect to uniQure’s sublicense to 
Chiesi, the Company is eligible to receive a percentage in the low twenties of all non-royalty compensation relating to the 
licensed technology or products that uniQure receives from Chiesi, a percentage in the low twenties of any royalties that 
uniQure receives from Chiesi based on sales of technology or products covered by the licensed patents, plus a mid single-
digit percentage of certain further royalties that uniQure receives from Chiesi based on sales of the Company’s licensed 
technology or products after the expiration of all licensed patents covering the product. Royalties the Company is eligible 
to  receive  pursuant  to  its  agreement  with  uniQure,  including  royalties  related  to  sales  made  by  Chiesi,  are  subject  to 
customary  royalty  stacking  deductions  in  the  event  that  uniQure,  or  any  of  its  sublicensees,  have  to  license  other 
technologies in order to commercialize Glybera. 

Pursuant to the terms of the Company’s agreement with UBC, the Company must pay to UBC a single-digit percentage of 
amounts the Company receives from sales of Glybera.  

The  following  table  is  a  summary  of  the  revenue  recognized  from  the  Company’s  collaborations  for  each  of  the  years 
ended December 31, 2016, 2015 and 2014.

(b)  Priority access agreement with Medpace: 

In August 2015, the Company entered into a priority access agreement with Medpace for the provision of certain clinical 
development services. Under the terms of the agreement, the Company has committed to using Medpace non-exclusively 
for  clinical  development  services  over  the  five  year  term  of  the  agreement.  In  consideration  for  priority  access  to 
Medpace  resources  and  preferred  service  rates,  the  Company  has  committed  to  $7,000 of  services  over  the  term  of  the 
agreement, $3,000 of which was paid in the year ended December 31, 2015. Of the amounts paid by the Company in 2015 
in  connection  with  the  priority  access  agreement,  $2,200  has  been  recorded  as  expenses  to  date  for  services  rendered, 
$392  has  been  recorded  as  current  prepaid  expenses  (2015  -  $1,010)  and  $408  as  long-term  prepaid  expenses  (2015  - 
$1,094) for the provision of future services as at December 31, 2016. 

(c)  Guarantees and indemnifications:  

The Company has entered into license and research agreements with third parties that include indemnification provisions 
that  are  customary  in  the  industry.  These  indemnification  provisions  generally  require  the  Company  to  compensate  the 
other  party  for  certain  damages  and  costs  incurred  as  a  result  of  third  party  claims  or  damages  arising  from  these 
transactions. 

The  maximum  amount  of  potential  future  indemnification  is  unlimited;  however,  the  Company  currently  holds 
commercial and product liability insurance. This insurance limits the Company’s exposure and may enable it to recover a 
portion of any  future amounts paid. Historically, the Company  has not  made any indemnification payments  under  such 
agreements and the Company believes that the fair value of these indemnification obligations is minimal. Accordingly, the 
Company has not recognized any liabilities relating to these obligations for any period presented. 

11. 

Income taxes:  

Income  tax  (recovery)  expense  varies  from  the  amounts  that  would  be  computed  by  applying  the  expected  Canadian  and 
provincial statutory income tax rate of 26% (2015 - 26%, 2014 - 26%) to loss before income taxes as shown in the following 
table:

Deferred  income  tax  assets  and  liabilities  result  from  the  temporary  differences  between  the  amount  of  assets  and  liabilities 
recognized for financial statement and income tax purposes. The significant components of the Company’s net deferred income 
tax assets are as follows:  

Deferred income tax assets 
Scientific research and experimental development pool 
Investment tax credits 
Non-capital losses 
Depreciable assets 
Deferred financing fees 
Other 
Less - valuation allowance

The realization of deferred income tax assets is dependent upon the generation of sufficient taxable income during future periods 
in which the temporary differences are expected to reverse. The valuation allowance is reviewed on a quarterly basis and if the 
assessment  of  the  “more  likely  than  not”  criteria  changes,  the  valuation  allowance  is  adjusted  accordingly.  A  full  valuation 
allowance continues to be applied against deferred income tax assets as the Company has assessed that the realization of such 
assets does not meet the “more likely than not” criteria.  

At  December 31,  2016,  the  Company  has  unclaimed  tax  deductions  for  scientific  research  and  experimental  development 
expenditures of $87,781 (2015 - $81,107) with no expiry.  

At December 31, 2016, the Company  has $20,160 (2015 - $18,875) of investment tax credits available to offset federal taxes 
payable and $7,624 (2015 - $7,385) of provincial tax credits available to offset provincial taxes payable in the future.  

At  December 31,  2016,  the  Company  has  non-capital  losses,  net  of  uncertain  tax  positions,  carried  forward  for  tax  purposes, 
which are available to reduce taxable income of future years of approximately $29,999 (2015 - $16,285).  

The investment tax credits and loss carry forwards expire over various years to 2036.  

As of December 31, 2016, the total amount of the Company’s unrecognized tax benefits of uncertain tax positions were $6,350 
(2015 - $6,350). If recognized in future periods, the unrecognized tax benefits would affect our effective tax rate. The Company 
recognizes potential accrued interest and penalties related to unrecognized tax benefits within the income tax provision. Interest 
and penalties have not been accrued at December 31, 2016 as none would be owing on the unrecognized tax benefits due to the 
availability of non-capital losses to shelter any potential taxable income arising thereon.  

The  Company  does  not  currently  expect  any  significant  increases  or  decreases  to  these  unrecognized  tax  benefits  within  12 
months of the reporting date.  

The Company files income tax returns in Canada and the United States, the jurisdictions in which the Company believes that it 
is subject to tax. In jurisdictions in which the Company does not believe it is subject to tax and therefore does not file income 
tax  returns,  the  Company  can  provide  no  certainty  that  tax  authorities  in  those  jurisdictions  will  not  subject  one  or  more  tax 
years (since the inception of the Company) to examination. Further, while the statute of limitations in each jurisdiction where an 
income tax return has been filed generally limits the examination period, as a result of loss carry-forwards, the limitation period 
for examination generally does not expire until several years after the loss carry-forwards are utilized. Other than routine audits 
by  tax  authorities  for  tax  credits  and  tax  refunds  that  the  Company  claims,  the  Company  is  not  aware  of  any  other  material 
income tax examination currently in progress by any taxing jurisdiction. Tax years ranging from 2003 to 2015 remain subject to 
Canadian income tax examinations.

Item 9. 

Changes in and Disagreements With Accountants on Accounting and Financial Disclosure 

None. 

Item 9A.  Controls and Procedures 

Evaluation of disclosure controls and procedures. Our management, with the participation of our Chief Executive Officer and 
our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2016. The term 
“disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other 
procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files 
or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s 
rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that 
information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and 
communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow 
timely decisions regarding required disclosure.  

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only 
reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit 
relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of 
December 31, 2016, our Chief Executive Officer and our Chief Financial Officer concluded that, as of such date, our disclosure 
controls and procedures were, in design and operation, effective at the reasonable assurance level.

Management’s Annual Report on Internal Control over Financial Reporting. Our management, with the participation of our 
Chief Executive Officer and our Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over 
our financial reporting, as such term is defined in Rule 13a-15(f) and Rule 15d-15(f) of the Securities Exchange Act of 1934. Our 
internal control over financial reporting is a process 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. Our internal 
control over financial reporting includes those policies and procedures that: 

(i) 

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of our assets; 

(ii)  provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial 

statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are 
being made only in accordance with authorizations of our management and directors; and 

(iii)  provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or 

disposition of our assets that could have a material effect on the financial statements. 

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, 

including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the 
inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting, including ours, no 
matter how well designed and operated, can only provide reasonable, not absolute, assurances. 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. Management has assessed the effectiveness of our internal 
control over financial reporting as at December 31, 2016. In making its assessment, management used the criteria set forth by the 
Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013) to 
evaluate the effectiveness of our internal control over financial reporting. Based on this assessment using those criteria, management 
has concluded that our internal control over financial reporting was effective as of December 31, 2016. 

Changes in internal control over financial reporting. There was no change in our internal control over financial reporting 
identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the 
three months ended December 31, 2016 that has materially affected, or is reasonably likely to materially affect, our internal control 
over financial reporting. 

Item 9B.  Other Information 

We have a written code of conduct that applies to all of our directors, officers and employees. In March 2017, our board of 
directors approved non-material changes to our code of conduct. A copy of the most up-to-date version of our code of conduct is 
available within the “Investors” section on our company website located at http://www.xenon-pharma.com and on SEDAR at
