ITEM 1. BUSINESS

Overview

PART I

We  are a clinical stage biopharmaceutical company engaged in the  research and  development of

novel anti-infective agents to treat serious infections, with a focus  on the pleuromutilin class of
antibiotics. We are developing our lead product  candidate, lefamulin, to be the  first  pleuromutilin
antibiotic available for systemic administration in humans. We are developing  both  intravenous, or IV,
and oral formulations of lefamulin for  the treatment of community-acquired bacterial pneumonia,  or
CABP and intend to develop lefamulin for  additional indications other than pneumonia. We have
completed a Phase 2 clinical trial of  lefamulin for acute bacterial skin and skin structure infections, or
ABSSSI. Based on the clinical results  of lefamulin  for  ABSSSI, as well  as its rapid  tissue distribution,
including substantial penetration into  lung  fluids  and lung immune  cells, we have  initiated  two pivotal,
international Phase 3 clinical trials of  lefamulin for the  treatment of  moderate to severe CABP.

We  initiated the first of our Phase 3  trials, which  we refer  to  as LEAP 1,  in September 2015 and

initiated the second trial, which we refer to as LEAP 2, in April  2016. These are the first clinical trials
we have conducted with lefamulin for  the treatment of CABP. Both trials  are designed to follow draft
guidance published by the FDA for the  development of drugs for  CABP and guidance from  the
European Medicines Agency, or EMA, for  the development of antibacterial  agents. Based on our
estimates regarding patient enrollment,  we expect to have top-line data from LEAP  1 in the  third
quarter of 2017. With respect to LEAP 2,  based on current projections, we expect  to  complete patient
enrollment in the fourth quarter of 2017, and we anticipate  receiving  top-line data for LEAP 2 in the
first quarter of 2018. If the results of these  trials are  favorable,  including achievement  of the primary
efficacy endpoints of the trials, we expect to submit applications for  marketing approval  for lefamulin
for the treatment of CABP in both the  United States  and Europe in 2018. We believe that lefamulin  is
well suited for use as a first-line empiric monotherapy for the treatment of CABP because of its novel
mechanism of action, spectrum of activity, including against multi-drug  resistant pathogens,
achievement of substantial drug concentrations in lung fluids and  lung immune cells, availability  as both
an IV and oral formulation and favorable  safety and tolerability profile.

The U.S. Food and Drug Administration,  or FDA, has  designated each of  the IV and oral
formulations of lefamulin as a qualified infectious  disease product, or QIDP, which  provides for  the
extension of statutory exclusivity periods  in the United States for an additional five years upon  FDA
approval of the product for the treatment of CABP  and  granted  fast track  designation  to  these
formulations of lefamulin. Fast track designation is granted by the FDA to facilitate the development
and expedite the review of drugs that treat serious  conditions  and fill an  unmet medical need. The fast
track designation for the IV and oral formulations  of lefamulin will allow for more frequent
interactions with the FDA, the opportunity for a  rolling  review of any new drug application, or NDA,
we submit and eligibility for priority review and a shortening  of  the FDA’s goal for  taking action on  a
marketing application from ten months to six months.

We  believe that pleuromutilin antibiotics can help address the major public  health  threat  posed by

bacterial resistance, which the World Health Organization, or WHO, characterized in  2010 as one  of
the three greatest threats to human health. Increasing  resistance to antibiotics used  to  treat  CABP is a
growing concern and has become an issue  in selecting  the appropriate  initial antibiotic treatment  prior
to determining the specific microbiological cause  of the infection,  referred  to  as empiric treatment. For
example, the U.S. Centers for Disease Control  and  Prevention,  or  CDC,  has classified Streptococcus
pneumoniae, the most common respiratory pathogen,  as a serious threat to human health as a result  of
increasing resistance to currently available  antibiotics.  In addition, the  CDC recently reported  on the
growing evidence of widespread resistance to macrolides, widely  used  antibiotics  that  disrupt bacterial
protein synthesis, in  Mycoplasma pneumoniae, a common cause of CABP that is associated with

significant morbidity and mortality. Furthermore, Staphylococcus aureus, including methicillin-resistant
S. aureus, or MRSA, which has also been designated as  a serious threat to human  health  by  the CDC,
has emerged as a more common cause  of  CABP in  some regions of the  world, and a possible pathogen
to be covered with empiric therapy.

In recognition of the growing need for the development of new antibiotics, recent regulatory
changes, including priority review and  regulatory  guidance enabling smaller  clinical trials,  have led to
renewed interest from the pharmaceutical industry in anti-infective  development. For example, the
Food and Drug Administration Safety and Innovation Act became law in 2012 and  included the
Generating Antibiotic Incentives Now  Act, or the GAIN Act, which  provides incentives, including
access to expedited FDA review for approval, fast track designation and five  years  of potential data
exclusivity extension for the development  of new QIDPs.

As a result of increasing resistance to antibiotics and  the wide array of potential  pathogens  that

cause  CABP, the current standard of care  for  hospitalized patients with CABP  whose  treatment is
initiated in the hospital usually involves  first-line empiric  treatment with a combination of antibiotics to
address all likely bacterial pathogens or  monotherapy with  a  fluoroquinolone antibiotic.  Combination
therapy presents the logistical challenge of  administering multiple drugs with  different dosing  regimens
and increases the risk of drug-drug interactions and the potential for serious  side effects.
Fluoroquinolones are associated with  safety and  tolerability  concerns, including a relatively high  risk for
developing  Clostridium difficile infections. In addition, in May 2016,  the FDA announced that an FDA
safety review has shown that fluoroquinolones, when used systemically, in the form  of tablets, capsules
and injectable, are associated with disabling  and potentially permanent serious  side effects that can
occur together. These side effects can  involve the tendons, muscles, joints,  nerves, and central nervous
system. Fluoroquinolones are typically  administered in combination  with other antibiotics, if
community-acquired MRSA is suspected. In addition, many currently available antibiotic therapies are
only available for IV administration and are prescribed for seven to 14 days,  meaning continued
treatment requires prolonged hospitalization or a  switch  to  a  different antibiotic administered  orally,
with the attendant risk that the patient  might respond differently.

Effective January 1, 2017, the Joint Commission  & Center for Medicare and Medicaid  Services, or

CMS, began requiring all U.S. hospitals to have Antibiotic Management guidelines, also known as
‘‘Stewardship’’ Committees, in place to identify antibiotics most appropriate  and targeted to each
individual patient’s infection. Past efforts  to ‘‘cast the widest net possible’’ with  broad-spectrum
antibiotics that affect many types of bacteria have  caused problems, such as C. difficile infections, by
killing good bacteria or increased antibiotic resistance in other bacteria in different areas of  the body.
Additionally, in 2016, the Infectious Disesase  Society of America and  the Society for Healthcare
Epidemiology of America, or IDSA/SHEA, updated their Antibiotic Stewardship guidelines for
antibiotic use. We believe that three  key  goals  from these guidelines are applicable to the  treatment of
CABP:

(cid:127) Reduce the risk of antibiotics associated with a  high risk of C. difficile infections;

(cid:127) Increase use of oral antibiotics as a  strategy to improve  outcomes or decrease costs; and

(cid:127) Reduce antibiotic therapy to the shortest effective  duration.

Pleuromutilins are semi-synthetic compounds  derived from a naturally occurring  antibiotic and
inhibit bacterial growth by binding to  a specific  site on  the bacterial ribosome that is responsible for
bacterial protein synthesis. We have developed  an understanding of how to  optimize characteristics of
the pleuromutilin class, such as antimicrobial spectrum, potency, absorption following oral
administration and tolerability, which  in  turn  led to our selection  and development of lefamulin, our
lead product candidate. We have completed a Phase 2 clinical trial for ABSSSI in which IV lefamulin
achieved a high cure rate against multi-drug resistant Gram-positive bacteria, including MRSA. In

The preclinical studies and clinical trials  we have  conducted to date suggest that lefamulin’s novel

mechanism of action is responsible for  the lack of  cross resistance observed  with other antibiotic classes
and a low propensity for development of  bacterial resistance to lefamulin. As a result  of the favorable
safety and tolerability profile we have  observed  in our clinical  trials to date, we believe lefamulin has
the potential to present fewer complications relative to the use  of current  therapies.  Based on our
research, we also believe that the availability of both IV  and  oral formulations of lefamulin, and an
option to switch to oral treatment, could reduce the length of a  patient’s  hospital stay and the overall
cost of care.

We  have evaluated lefamulin in more  than 440 patients  and subjects  in seventeen completed

Phase 1 clinical trials and a Phase 2 clinical trial in ABSSSI. In our  Phase 1 clinical trials, we have
characterized the clinical pharmacology of  the IV formulation of lefamulin and  shown oral
bioavailability of a tablet formulation  of lefamulin with rapid  tissue  distribution, including  substantial
penetration into lung fluids and lung immune cells. In our Phase  2 clinical trial evaluating the safety
and efficacy of two different doses of  the IV formulation of lefamulin administered  over five to 14 days
compared to the antibiotic vancomycin  in  patients with ABSSSI,  the  clinical success rate at test of cure,
or TOC, for lefamulin was similar to  that of vancomycin. Lefamulin has been well tolerated  in all our
clinical trials to date when administered by IV and oral routes.  The frequency of adverse events  that
we observed in our Phase 2 clinical trial in  ABSSSI was similar for patients treated  with IV lefamulin
and patients treated with vancomycin.

Based on the clinical results of lefamulin  for the  treatment of ABSSSI,  as well as its  rapid  tissue

distribution, including substantial penetration into the lung, we are evaluating lefamulin  for the
treatment of moderate to severe CABP  in  two international  Phase 3 clinical trials. We are initially
pursuing the development of lefamulin for CABP because of the limited development of new antibiotic
classes for this indication over the past 15  years,  our  belief that there exists a significant  unmet medical
need for a first-line empiric monotherapy  that addresses  the growing development and spread  of
bacterial resistance, as well as recently clarified FDA guidance regarding  the approval pathway.  We
initiated the first of these trials in September 2015 and the  second trial in April 2016. We are also
further characterizing the clinical pharmacology of  lefamulin in several  additional Phase 1 clinical trials.

We  plan to pursue a number of additional opportunities for lefamulin, including beginning a

development program for use in pediatric patients and potentially for the treatment  of ABSSSI. In
addition, as an antibiotic with potent  activity against a wide  variety of multi-drug resistant pathogens,
including MRSA, we may explore development of lefamulin in other  indications, including ventilator-
associated bacterial pneumonia, or VABP,  hospital-acquired bacterial pneumonia, or HABP, sexually
transmitted infections, or STIs, osteomyelitis and prosthetic  joint  infections. Through our research and
development efforts, we have also identified a topical pleuromutilin product  candidate, BC-7013, which
has completed a Phase 1 clinical trial.

We  own exclusive, worldwide rights to lefamulin. Lefamulin is  protected by issued patents  in the

United States, Europe and Japan covering composition  of matter,  which are  scheduled to expire  no
earlier than 2028.  We also have been  granted  patents for  lefamulin  relating to process and
pharmaceutical crystalline salt forms in the  United States, which are scheduled  to  expire no earlier than
2031. In addition, we own a family of pending patent applications directed  to  pharmaceutical
compositions of lefamulin, which if issued  would be scheduled to expire no  earlier than  2036.

Our Strategy

Our goal is to become a fully integrated biopharmaceutical  company focused on  the research,
development and commercialization of novel anti-infective products. The key elements  of our  strategy
to achieve this goal are:

(cid:127) Complete Phase 3 clinical development of  lefamulin for  CABP. We are devoting a significant portion

of our financial resources and business  efforts to completing  the clinical development of
lefamulin for the treatment of CABP.  We initiated two  international Phase 3 clinical trials of
lefamulin for the treatment of moderate to severe  CABP. We initiated  the first of these trials in
September 2015 and the second trial in the April 2016. Based  on our estimates  regarding patient
enrollment, we expect to have top-line data from LEAP 1 in the third quarter of 2017.  With
respect to LEAP 2, based on current projections, we expect to complete patient enrollment in
the fourth quarter of 2017, and we anticipate receiving top-line data  for LEAP 2 in  the first
quarter of 2018. If the results of these  trials are  favorable, including achievement  of the primary
efficacy endpoints of the trials, we expect to submit applications for  marketing approval  for
lefamulin for the treatment of CABP in  both the United States  and Europe  in 2018.

(cid:127) Maximize the commercial potential of lefamulin for  CABP. We own exclusive, worldwide rights to
lefamulin. We expect that our initial target patient population for lefamulin will consist  of
patients with moderate to severe CABP. If lefamulin receives marketing  approval from the  FDA
for the treatment of CABP, we plan to  commercialize it in the United  States with our own
targeted hospital sales and marketing organization that we plan  to  establish. We believe that we
will be able to effectively communicate  lefamulin’s differentiating characteristics  and key
attributes to clinicians and hospital pharmacies with  the goal  of  establishing favorable formulary
status for lefamulin. If lefamulin receives marketing  approval outside the United  States for  the
treatment of CABP, we expect to utilize  a variety of types of collaboration, distribution and
other marketing arrangements with one or  more  third  parties to commercialize lefamulin  in such
markets. We also are conducting pediatric formulation  development activities to support clinical
trials of lefamulin for pediatric use for  CABP.

(cid:127) Pursue the continued development of lefamulin in additional indications. We plan to pursue the

continued development of lefamulin for indications in addition to CABP.  For example, we are
conducting formulation development activities  for lefamulin for  use in  pediatric  patients, and
potentially for the treatment of ABSSSI. In addition, we  are evaluating whether  to  pursue
studies  of lefamulin in patients with VABP or HABP. We believe that  lefamulin’s product profile
also provides the opportunity to expand to other indications beyond pneumonia. For example,
investigation of the tolerability of higher single doses  of lefamulin could also  support use  of
lefamulin for the treatment of STIs. In addition, we may explore longer duration of treatment
with lefamulin to support development of a treatment for osteomyelitis and prosthetic joint
infections. We believe that lefamulin would be differentiated  from  other treatment  options  for
each  of these potential uses because of lefamulin’s novel mechanism of action, spectrum of
activity, including activity against multi-drug resistant  pathogens, achievement of substantial
concentrations in relevant tissues, availability as both  an IV and oral formulation and favorable
safety and tolerability profile.

(cid:127) Advance the development of other pleuromutilin product candidates  and possibly  compounds  in other
classes. We are currently focused on developing additional pleuromutilin product candidates
through our deep understanding of this  class of antibiotics. Our product candidate BC-7013  has
completed a Phase 1 clinical trial. We believe  that this  pleuromutilin compound is  well suited  for
the topical treatment of a variety of Gram-positive infections, including  uncomplicated  skin and
skin structure infections, or uSSSIs. Furthermore, we own diverse  libraries of compounds in

other antibacterial classes, such as ß-lactams and acremonic acids, which are a potential  basis for
the discovery and development of novel  antibacterial agents.

(cid:127) Evaluate business development opportunities and potential collaborations. We plan to evaluate the
merits of entering into collaboration agreements  with other pharmaceutical or biotechnology
companies that may contribute to our ability to efficiently  advance our  product candidates, build
our  product pipeline and concurrently advance a range  of research and  development programs.
Potential collaborations may provide  us with funding and access to the scientific,  development,
regulatory and commercial capabilities of the  collaborators. We also plan  to  encourage local and
international government entities and  non-government organizations to provide additional
funding and support for our development programs. We  may  expand our product pipeline
through opportunistically in-licensing or  acquiring  the rights to complementary products, product
candidates and technologies for the treatment of  a range of infectious  diseases.

lefamulin specifically for CABP. Our completed Phase  2 clinical trial evaluated lefamulin in
patients with ABSSSI. We have obtained input from the  FDA  and  select European authorities,
including reaching agreement with the FDA  on a  Special Protocol Assessment, or  SPA,  regarding
the study design of our first Phase 3 clinical trial, in  anticipation of submitting applications  for
marketing approval for lefamulin for  the treatment of CABP in both the  United States and

Background

Anti-Bacterial Market and Scientific Overview

Bacteria  are broadly classified as Gram-positive or Gram-negative.  Gram-positive bacteria possess

a single membrane and a thick cell wall  and turn dark-blue or violet  when subjected  to  a laboratory
staining  method known as Gram’s method. Gram-negative  bacteria  have a  thin cell wall layered
between an inner cytoplasmic cell membrane  and  a bacterial outer membrane  and, as a result,  do  not
retain the violet stain used in Gram’s  method. Antibiotics that are active against both  Gram-positive
and Gram-negative bacteria are referred to as broad spectrum, while  those that are  active  only  against
a select subset of Gram-positive or Gram-negative bacteria are referred to as narrow spectrum.
Bacteria  that cause infections are often referred  to  as bacterial pathogens. Because  it often takes from
24 to 48 hours to definitively diagnose the particular  bacterial  pathogen  causing an infection,  the
causative pathogen often remains unidentified and narrow spectrum antibiotics are not generally used
as empiric monotherapy for first-line  treatment of  hospitalized patients with serious  infections.

Since the introduction of antibiotics in the 1940s, numerous new antibiotic classes have  been
discovered and developed for therapeutic  use. The development of new  antibiotic classes  and new
antibiotics within a class is important because of the  ability  of  bacteria to develop resistance to existing
mechanisms of action of currently approved antibiotics. However, the  pace of discovery and
development of new antibiotic classes slowed considerably in  the past few decades. The CDC estimates
that the pathogens responsible for more than 70% of U.S. hospital infections are  resistant to at  least
one of the antibiotics most commonly used to treat them. The  CDC also estimated in 2013,  based on
data collected from evaluations performed between 2006 and 2011, that annually in  the United States
at least two million people become infected with bacteria that are resistant to antibiotics and at least
23,000 people die as a direct result of these  infections.

Antibiotic resistance is primarily caused by genetic mutations in bacteria selected  by  exposure to

antibiotics that do not kill all of the bacteria. In addition to mutated bacteria being resistant to the
drug used for treatment, many bacterial  strains can also become  cross-resistant, meaning  that  they
become  resistant to multiple classes of antibiotics.  As a result,  the effectiveness of many  antibiotics has
declined, limiting physicians’ options  to treat serious  infections  and exacerbating a global  health  issue.
For example, the WHO estimated in  2014 that people with infections caused by MRSA, a highly
resistant form of bacteria, are 64% more likely to die than  people with  a non-resistant form  of the
infection. Resistance can increase the  cost of healthcare because of the potential for lengthier hospital
stays and more intensive care. Growing antibiotic resistance globally, together with the  low level  of
investment in research and development, is considered  one  of  the biggest  global health threats. In 2010,
the WHO stated that antibiotic resistance is one  of  the three greatest threats  to  human health. Partially
in response to this threat, the U.S. Congress passed the  GAIN Act  in 2012, which provides incentives,
including access to expedited FDA review for  approval, fast track designation  and five years of
potential data exclusivity extension for the  development of new  QIDPs. Additional legislation  is also
being considered in the United States,  including the  Antibiotic  Development to Advance Patient
Treatment Act of 2013, which is intended  to accelerate the development of anti-infective products, and
the Developing an Innovative Strategy for Antimicrobial Resistant Microorganisms Act of 2014,  which
is intended to establish a new reimbursement  framework  to enable  premium pricing of anti-infective
products.

In 2009, sales of antibiotics totaled approximately $42 billion  globally. Although judicious use of

antibiotics is important to reduce the rate  of antibiotic  resistance,  this  approach  alone  cannot fully
address the threat from increasing antibiotic resistance.  New antibiotics,  and particularly  new antibiotic
classes, are needed to ensure the availability  of effective antibiotic therapy in the  future.

Community-Acquired Bacterial Pneumonia  (CABP)

Market Overview

The WHO estimated in 2002 that there were approximately 450 million pneumonia  cases reported
per  year worldwide, causing approximately 4.0 million deaths in 2002.  According to an article published
in 2011 in the peer-reviewed medical  journal Therapeutic Advances in Respiratory Disease, the annual
incidence of community-acquired pneumonia  is between five and 11 cases per 1,000 people, with the
incidence rate rising in elderly patients. In a study published  in 2004 in  the peer-reviewed medical
journal Clinical Infectious Diseases in which more than 46,000 people in the  state  of Washington  were
monitored over three years, the incidence of CABP among  those 65 to 69 years of age was 18.2 cases
per  1,000 people per year and increased to 52.3 cases per 1,000 people  per year in  those over 85 years
of age.

The U.S. National Center for Health Statistics estimated that  between 1988 and 1994  there were
approximately 5.6 million cases of pneumonia per year in the United States. More recently, based  on
our  combined analysis of the CDC’s 2007  National Ambulatory  Medical Care Survey, the  National
Hospital Ambulatory Medical Care Survey  and 2013 data  from the Healthcare Cost  and Utilization
Project we estimate that over 5.0 million  adults are treated  annually  for  CABP in  the United States  and
that the majority of these adult CABP  patients  have their treatment  initiated  in a hospital,  including
emergency departments. According to the  Healthcare Cost and  Utilization Project,  or HCUP,  in 2013,
approximately 3.1 million adults sought  treatment  in a U.S. hospital  for CABP.  In addition, in  2013,
approximately 2.4 million adults were admitted to U.S.  hospitals for in-patient  care with a diagnosis of
CABP and approximately 700,000 adults were  seen in  an emergency department at U.S. hospitals  for
treatment of CABP and then released.

Additionally, in 2014, based on CDC  data approximately 50,000 patients  died  from CABP  in the
United States. Based on data collected  from July 1, 2012 through June 30, 2015, on the  Medicare.gov
Hospital Compare website, the current national  rate of readmissions for Medicare pneumonia patients
is 17.1%, which is the percentage of  patients  who have  had a recent hospital  stay that must return to a
hospital for unplanned care within 30 days of being discharged. The national average death rate  for
Medicare pneumonia patients, excluding Medicare Advantage plan data, is 16.3%, which is the
percentage of patients who die, for any reason, within  30 days of  admission to a hospital.

Based on data from Arlington Medical Resources, or  AMR,  a  leading provider  of medical data
from hospitals and other healthcare facilities, who reported  that the number  of antibiotic  treatment
courses  for CABP adult patients in hospitals  in the United States exceeded  6.8 million for  full-year
2015, we estimate approximately 5.3 million of  these CABP courses were for  IV/injectable antibiotics
for adult CABP patients, while approximately 1.5 million CABP oral antibiotic courses were  prescribed
for adult CABP patients in the hospital setting.  Additionally, for the twelve months ending
September 30, 2016, Source Health Solutions estimates that  once adult  CABP patients are  discharged
home from U.S. hospitals, approximately  4.2 million  antibiotic  oral  prescriptions are written annually
for their outpatient antibiotic treatment.  Relative  to  the approximately 6.6 million adult  CABP
outpatient oral antibiotic prescriptions that Health  Source Solutions estimates are written over  the
same time-period, approximately 6 out  of  every 10 oral antibiotic prescriptions  for adult CABP  results
as a transition of care from hospital-initiated  treatment to outpatient therapy. The remaining CABP
prescriptions originate from prescribers in community clinics, primary care  offices and at  other
non-hospital based sites of urgent care.

Causes of CABP

Pneumonia can be caused by a variety of micro-organisms, with bacteria  being the  most common
identifiable cause. CABP refers to bacterial pneumonia that is acquired outside of a hospital setting.
Signs and symptoms of CABP include cough, fever, sputum production and chest  pain. A number  of

different types of bacteria can cause  CABP,  including  both  Gram-positive and Gram-negative  bacteria.
Pneumonia that is caused by atypical bacterial  pathogens  often  has different symptoms and responds to
different antibiotics than pneumonia  caused by pathogens referred to as typical bacteria. However,
atypical bacteria are not uncommon.  The  most  common bacterial pathogens noted in current treatment
guidelines from the Infectious Diseases Society of America, or IDSA, for hospitalized CABP patients
who are not in the intensive care unit are  Streptococcus pneumoniae, Mycoplasma pneumoniae,
Haemophilus influenzae, Chlamydophila  pneumoniae, and Legionella species. In addition, IDSA notes the
emergence of resistance to commonly  utilized antibiotics for CABP, specifically drug-resistant
S. pneumoniae and community-acquired MRSA, or CA-MRSA, as a major consideration in choosing
empiric therapy. However, a majority of patients do not have  a pathogen identified using routine
diagnostic tests available to physicians.

Currently Available Treatment Options

In 2007, based on the most likely bacteria to cause CABP, IDSA and the American  Thoracic
Society, or ATS, recommend empiric treatment  of  hospitalized  patients with CABP who do not require
treatment in an intensive care unit with either:

(cid:127) a combination of a cephalosporin,  an antibiotic that disrupts the cell wall of bacteria,  plus a

macrolide, an antibiotic that disrupts  bacterial protein  synthesis;  or

(cid:127) monotherapy with a respiratory fluoroquinolone, an antibiotic that disrupts bacterial protein

synthesis.

In the event CA-MRSA is suspected,  these guidelines recommend that  vancomycin, an antibiotic

that disrupts the cell wall of bacteria,  or  linezolid,  an antibiotic  that disrupts bacterial protein  synthesis,
be used or added to the current regimen.

In addition, physicians need to be aware of  the local  susceptibility profiles of the common  bacterial

pathogens associated with CABP because  of  increasing resistance  to  first-line antibiotics.  For example,
rates of pneumococcal resistance to recommended  first-line macrolides exceed  40% in some areas,
while resistance in M. pneumoniae associated with severe disease has been  recently  reported by the
CDC  in the United States.

Limitations of Currently Available Treatment Options

When confronted with a new patient  suffering  from a serious  infection caused by an unknown

pathogen, a physician may be required  to  quickly initiate first-line  empiric antibiotic treatment,  often
with a combination of antibiotics, to  stabilize the patient prior to definitively diagnosing the  particular
bacterial infection. However, currently available antibiotic therapies for first-line empiric treatment of
CABP suffer from significant limitations.

Bacterial Resistance and Spectrum of  Activity

As a result of bacterial resistance, the effectiveness of many  antibiotics has declined. For example,
the CDC estimates that in 30% of severe  S. pneumoniae cases, the bacterial pathogen is fully resistant
to one or more clinically relevant antibiotics,  with 44% of strains  resistant to a  macrolide in the United
States. In addition, fluoroquinolone resistance in S. pneumoniae has increased from less than 0.5% to
more than 3% of cases in some regions of North  America, which  parallels increased total
fluoroquinolone prescriptions. Antibiotic  resistance has a significant impact on mortality  and
contributes heavily to healthcare system costs worldwide. According to the  CDC, cases  of resistant
pneumococcal pneumonia result in 32,000 additional doctor  visits, approximately 19,000  additional
hospitalizations and 7,000 deaths each year. These cases are associated with  $96 million in excess
medical cost per year in the United States. IDSA/ATS  guidelines  recommend empiric treatment that

provides broad spectrum antimicrobial  coverage. None  of  the currently available treatment options
provides a spectrum of antibacterial  coverage as a monotherapy that  sufficiently covers all of the most
common bacterial causes of CABP, including  multi-drug resistant strains.

Difficult, Inconvenient and Costly Regimens

Currently available antibiotics used to  treat CABP and other serious infections  can be difficult,

inconvenient and costly to administer.  Physicians typically prefer IV administration for patients
hospitalized with more serious illness to ensure  adequate delivery  of  the drug rapidly.  Many IV
antibiotics are prescribed for seven to 14  days  or more and patients can be hospitalized for  much  or all
of this period or require in-home IV  therapy. The  diagnosis  related  group, or DRG, reimbursement
system often used in the U.S. hospital setting  pays a fixed fee for an episode of CABP that may not
fully compensate hospitals for the duration of hospitalized care. Prolonged IV treatment  that  extends
the period of hospitalization may cause  hospital costs to increase  in excess of  the fixed reimbursement
fee, resulting in significant negative impact  on healthcare institutions.  In addition, to address all likely
bacterial pathogens in a patient with  a more serious illness, IDSA  guidelines recommend using a
combination of antibiotics. Combination therapy presents the logistical  challenge of administering
multiple drugs with different dosing regimens  and  increases the risk of drug-drug interactions. While IV
treatment delivers the drug more rapidly  than is possible orally,  once a patient is  stabilized, oral
treatment with the same drug would allow for more convenient and cost-effective out-patient treatment.
Because many commonly used antibiotics  are only available in  IV form, a switch to an  oral  therapy
requires changing to a different antibiotic,  which may be less effective for  the patient.

Adverse Effects

Currently available antibiotic therapies can have serious side  effects.  These side effects may include

severe allergic reaction, decreased blood pressure, nausea and vomiting, suppression of platelets, pain
and inflammation at the site of injection,  muscle, renal  and oto-toxicities,  optic and peripheral
neuropathies and headaches. At times,  these side effects  may  be  significant  and require  discontinuation
of therapy. As a result, some treatments  require  clinicians to closely  monitor  patients’ blood levels and
other parameters, increasing the expense  and inconvenience of treatment.  This risk may be increased
with combination therapy, which exposes patients to potential  adverse effects from each of the
antibiotics used in treatment. For example,  fluoroquinolones  are  associated  with tendon rupture and
peripheral neuropathy. In addition, fluoroquinolones have been  associated with an  increased  frequency
of C. difficile  colitis,  an overgrowth of a bacteria in the  colon that  produces a toxin that results  in
inflammation of the colon and repeated  bouts of watery diarrhea. This has resulted in limitations  on
the use of fluoroquinolones in several countries. In November 2015,  the FDA convened an Advisory
Committee meeting to review the benefits and risks  of  fluoroquinolones  in less severe indications, such
as uncomplicated UTI, acute bacterial sinusitis and  acute bacterial exacerbations of chronic bronchitis.
Based on the committee’s recommendation, in  July 2016,  the FDA approved  changes to the labels of
fluoroquinolones to indicate that fluoroquinolones should  be reserved for use  in patients who have  no
other treatment options for the indications mentioned above, because the risk  of  these  serious side
effects generally outweighs the benefits in  these patients. These  changes included a requirement that a
separate patient Medication Guide be  given with each prescription that  describes  the safety issues
associated with this class of drugs.

Lefamulin

Overview

We  are developing lefamulin to be the first pleuromutilin antibiotic available for systemic

administration in humans. Lefamulin is  a  semi-synthetic derivative of the naturally occurring antibiotic,
pleuromutilin, which was originally identified from a  fungus called Pleurotus mutilis. Lefamulin inhibits

the synthesis of bacterial protein, which is required for  bacteria to grow. Lefamulin acts by binding to
the peptidyl transferase center, or PTC,  on the bacterial ribosome in  such a way that it  interferes with
the interaction of protein production  at two key sites  known as the ‘‘A’’ site  and the  ‘‘P’’ site,  resulting
in the inhibition of bacterial proteins and the  cessation  of bacterial growth.  Lefamulin’s  binding  occurs
with high affinity, high specificity and  at molecular sites  that are different than other antibiotic classes.
We  believe that lefamulin’s novel mechanism  of  action is  responsible  for the  lack  of cross-resistance
with other antibiotic classes that we have observed in  our preclinical studies  and clinical trials and a
low propensity for development of bacterial resistance to lefamulin. The binding of  lefamulin  to  the
PTC on the bacterial ribosome is depicted in  the graphic  below.

10AUG201719560980

We  are developing both IV and oral formulations of lefamulin.  We believe that lefamulin is well
suited to be used empirically as monotherapy for the treatment of respiratory  tract  infections, such  as
CABP, because of its spectrum of antibacterial activity against both the typical and atypical  pathogens
causing CABP, including multi-drug resistant pathogens such  as MRSA. In  preclinical studies  and in
Phase 1 clinical trials, lefamulin achieved  substantial concentrations  in the  epithelial lining  fluid,  or
ELF, of the lung, the site infected during  pneumonia.  Lefamulin also provides  the ability to switch from
IV to oral therapy with the same active ingredient.

We  have completed a Phase 2 clinical trial of lefamulin for  ABSSSI.  Based on  the clinical  results
of lefamulin for ABSSSI, as well as its rapid tissue distribution, including substantial  penetration into
lung  fliuds and lung immune cells, we  initiated two international, pivotal Phase 3 clinical trials of
lefamulin for the treatment of moderate to severe  CABP. These  are  the  first  clinical trials  we have
conducted with lefamulin for the treatment of CABP. We  initiated  the first of these trials in  September
2015 and the second trial in April 2016.  We designed these trials  to  follow  draft guidance published  by
the FDA for the development of drugs for  CABP and guidelines from the EMA  for the  development
of antibacterial agents, as well as our  SPA with the FDA regarding the study design of our first Phase 3
clinical trial. According to the draft FDA  guidance  and FDA feedback, either a Phase 3 clinical trial for
CABP, supported by evidence of antibacterial activity accrued  during  a  clinical  development program
for another indication, such as ABSSSI,  or two  Phase 3  clinical trials for  CABP, may provide  sufficient
evidence of efficacy in CABP.

Based on our estimates regarding patient  enrollment,  we expect to have top-line data from LEAP

1 in the third quarter of 2017. With respect to LEAP  2, based on current  projections, we expect to
complete patient enrollment in the fourth quarter of 2017, and we anticipate receiving  top-line data for
LEAP 2 in the first quarter of 2018. If the results of these trials are favorable,  including achievement
of the primary efficacy endpoints of  the trials, we expect to submit applications for marketing  approval
for lefamulin for the treatment of CABP  in  both  the United States  and  Europe in  2018. We  submitted
to the FDA an investigational new drug  application, or IND,  for  the IV formulation of lefamulin  in
September 2009 and an IND for the oral  formulation of lefamulin in January  2015. The FDA has
designated each of the IV and oral formulations  of  lefamulin as a QIDP  and also granted fast track
designations to each of these formulations of lefamulin.

Key Attributes of Lefamulin

We  believe that the combination of the  following  key  attributes of lefamulin, observed in clinical

trials and preclinical studies, differentiates lefamulin  from currently available antibiotics and  make
lefamulin well suited for use as a first-line empiric  monotherapy for the  treatment of CABP.

Broad Spectrum of Activity and Low Propensity  for the  Development of Bacterial  Resistance

We  expect lefamulin’s spectrum of antibacterial  activity against typical  and atypical pathogens

could eliminate the need to use a combination of antibiotics for  the treatment of CABP. In our
completed Phase 2 clinical trial, IV lefamulin  achieved a high cure rate against multi-drug resistant
Gram-positive bacteria, including MRSA.  In addition, in  preclinical studies,  lefamulin  showed activity
against a variety of Gram-positive bacteria, including  S. pneumoniae and S. aureus, that are resistant to
other classes of antibiotics, Gram-negative bacteria, including  H. influenzae and M. catarrhalis, and
atypical bacteria, including C. pneumoniae, M. pneumoniae and L. pneumophila. Included in lefamulin’s
spectrum of activity are all bacterial pathogens identified by IDSA  as the most  common causes of
CABP for hospitalized patients who  are  not in the  intensive care unit, as  well as strains of the above
listed bacteria that are resistant to other classes of antibiotics, including penicillins,  cephalosporins,
fluoroquinolones and macrolides.

Based on observations from our preclinical  studies and  clinical trials of lefamulin, as  well as
industry experience with pleuromutilins used in veterinarian medicine over the  last 30  years,  we believe
that lefamulin’s novel mechanism of action is  responsible for the lack of cross-resistance observed with
other antibiotic classes and a low propensity for development of bacterial resistance to lefamulin.

Convenient Dosing Regimen; Potential  for Switching from IV to Oral Treatment

We  have developed both an IV and oral formulation of  lefamulin,  which we are utilizing in  our
Phase 3 clinical trials of lefamulin for the  treatment of CABP. The administration of lefamulin as a
monotherapy avoids the need for the complicated  dosing regimens typical of multi-drug  cocktails. We
believe the availability of both IV and  oral administration, and  an option to switch to oral treatment,
would be more convenient for patients  and could reduce the  length of a patient’s hospital stay and the
overall cost of care. The potential reduction in the  overall  cost of  care could be particularly meaningful
to healthcare institutions, as the DRG reimbursement  system pays a fixed  fee for the treatment of
CABP regardless of the length of hospital  stay.  We believe  that our  Phase 3  trial design will permit us
to submit for approval of both IV and oral  formulations of lefamulin, subject  to  obtaining  favorable
results, including achievement of the  primary efficacy endpoints of the trials.

Favorable Safety and Tolerability Profile

We  have evaluated lefamulin in over 440  subjects and patients in our  completed Phase  1 and
Phase 2 clinical trials. In these trials,  lefamulin has exhibited a favorable safety and tolerability  profile.
In our Phase 2 clinical trial of lefamulin, no patient suffered any serious adverse events that were
determined to be related to lefamulin, and safety and tolerability were comparable to vancomycin, the
control therapy in  the trial. In addition,  no clinically significant  change in electrocardiogram, or ECG,
was measured, and no drug-related cardiovascular adverse events  were reported.  Furthermore, we
believe the use of  lefamulin as a monotherapy  would present fewer potential  complications relative to
the use of multiple antibiotics as combination therapy.  We are also continuing to evaluate the safety
and tolerability of lefamulin in our Phase  3 clinical  trials.

Phase 3 Clinical Trials

We  are conducting a pivotal clinical trial  program of  lefamulin for  the treatment of  CABP

consisting of two international Phase  3 clinical  trials. We  initiated  the first of these trials in  September

2015 and the second trial in April 2016.  We designed these trials  to  comply with the  guidelines of The
International Conference on Harmonisation of Technical Requirements  for  Registration of
Pharmaceuticals for Human Use, which are currently used as guidance by the FDA, and good clinical
practices. We are conducting these trials  at centers in  the United States,  Europe, Asia and  selected
countries in the southern hemisphere.  We  are currently enrolling patients in each of  these clinical trials
in several countries and are continuing  with the regulatory steps necessary  to  initiate and conduct these
trials, including submission of the trial  protocol and relevant information about lefamulin  to  local
regulatory authorities and ethics review  committees in  other countries.

First Phase 3 Clinical Trial

We  designed our Phase 3 clinical trials to follow the  draft guidance published by the FDA for the

development of drugs for CABP and  guidance from the EMA for the development  of  antibacterial
agents with the goal of positioning lefamulin as a first-line empiric monotherapy for  the treatment of
CABP. We reached agreement with the FDA in  September 2015 on a  SPA regarding the study  design
for our  first Phase  3 clinical trial and obtained input from  select European authorities  in anticipation of
submitting a new drug application with  the FDA and a  marketing  authorization application, or MAA,
with the EMA, in each case, for the treatment  of CABP.  In April 2016, we reached  agreement with the
FDA regarding an amendment to the SPA. We  also plan  to  conduct a number  of  studies to support
FDA approval of lefamulin, including  studies in patients  with hepatic insufficiency and  renal
impairment. If we complete the two Phase 3 clinical trials of lefamulin when  we anticipate and obtain
favorable results, we expect to submit an  NDA to the FDA and an MAA  to  the EMA in  2018.

Our first Phase 3 clinical trial of lefamulin for  the treatment  of CABP  is a multi-center,
randomized, controlled, double-blind study comparing lefamulin  to  moxifloxacin, a fluoroquinolone
antibiotic. Linezolid (or matching placebo for  the lefamulin arm), can be added to treatment if an
investigator suspects that a patient is  infected  with MRSA prior to randomization, as moxifloxacin  is
not approved to treat MRSA. This trial  is designed to assess the  non-inferiority of lefamulin  compared
to moxifloxacin, with or without linezolid.  We  expect the  study population  will include  male and  female
patients of at least 18 years of age. Our study design  targets the enrollment of approximately 550
patients, of which we expect a small  proportion will require  linezolid to be  added.

Lefamulin will be dosed at 150 mg IV every  12 hours. The comparator drugs will be dosed
according to their approved labeling, with moxifloxacin dosed  at 400 mg IV  daily  and linezolid at 600
mg IV every 12 hours. Based on pre-defined criteria, investigators  will have  the option  to  switch
patients to oral therapy after three days (at least six doses) of IV  study medication.  Lefamulin will be
administered orally as one 600 mg tablet  every 12 hours,  moxifloxacin at 400 mg daily and linezolid at
600 mg every 12 hours. Based on the  pharmacokinetic profile of lefamulin, we  expect oral dosing  of
one 600 mg tablet every 12 hours to  have a  similar therapeutic  benefit  as IV  dosing of 150 mg every
12 hours.

All patients enrolled in this trial will  be  classified as Pneumonia Outcomes Research Team, or
PORT, severity of at least 3 on a scale  of  1 to 5,  which corresponds to moderate  to  severe clinical
disease. Patients who have previously taken no more than one dose  of  a short acting, potentially
effective antibiotic for the treatment of  the current  CABP episode  within 24 hours of receiving the first
dose of study medication will be allowed  to  participate in the  trial but will comprise only up to 25% of
the total intent to treat, or ITT, population. Patients  with confirmed  S. aureus bacteremia will be
discontinued from the trial. Investigators  will obtain baseline Gram’s stain  and culture  of suitable
specimens from the site of infection.  Patients will be treated for  a  minimum seven days and a maximum
of ten days.

We  will assess patients between 72 and 120 hours from the start of treatment, at  the end of
treatment, or EOT, within 48 hours of  administration  of the  final dose of study medication,  at a TOC

visit between five and ten days after administration of the final dose  of study  medication and at  a
telephone follow-up 30 days after administration of the  first dose  of  study medication.

We  will evaluate the following patient  subsets:

(cid:127) an ITT population consisting of all randomized patients  regardless  of whether they have received

study medication;

(cid:127) a modified intent to treat, or MITT, population consisting  of  all randomized  subjects who  receive

any amount of study drug;

(cid:127) a microbiological intent to treat, or microITT, population  consisting of  all subjects in the ITT

population who have at least one baseline bacterial pathogen  known to cause  CABP, Legionella
pneumophila from an appropriate microbiological  specimen, or  CABP caused by Mycoplasma
pneumoniae or Chlamydophila pneumoniae;

(cid:127) a clinically evaluable, or CE, population which is a subset of the ITT population that will include

subjects who meet the criteria for CABP and  who  have  received at  least the pre-specified
minimal amount of the intended dose of study drug  and duration  of  treatment, do  not  have an
indeterminate response based on the investigator’s assessment of clinical response at EOT for
the CE-EOT population and at TOC  for the CE-TOC population, did not receive concomitant
antibacterial therapy, other than adjunctive linezolid, that is potentially effective against  CABP
pathogens (except in the case of clinical  failure) from the first dose of study drug through the
EOT visit for the CE-EOT population and  through  the TOC visit for the  CE-TOC population,
and for whom there are no other confounding factors that  interfere with  the assessment of  the
outcome; and

(cid:127) a microbiologically evaluable, or ME, population consisting of all subjects who meet the  criteria
for inclusion in both the microITT, CE-EOT  and ME-EOT populations or the CE-TOC and
ME-TOC populations.

The primary efficacy endpoint for the trial for  the FDA is the proportion of  patients in the ITT
population for each of the lefamulin  treatment group and the moxifloxacin treatment group who  are
alive, have improvement in at least two of  the four cardinal symptoms of CABP as outlined in the
current FDA guidance, have no worsening in any of the four cardinal symptoms  of CABP and have not
received a concomitant antibiotic (other  than linezolid) for the treatment  of CABP up through
120 hours after the first dose of lefamulin. This endpoint  is also referred to as early clinical response.
The four cardinal symptoms of CABP, as outlined  in  the current FDA guidance,  are difficulty
breathing, cough, production of purulent sputum and chest pain.

The primary efficacy endpoint for the EMA is the clinical success rate at the TOC visit for

lefamulin in both the CE and MITT populations  compared to moxifloxacin. Clinical success is based on
the investigator’s assessment that a patient  has clinically responded to lefamulin, which means that the
patient has complete resolution or significant improvement of all local and systemic  signs and
symptoms of infection such that no additional antibiotic treatment is administered for the treatment of
the current episode of CABP.

Key secondary efficacy and exploratory endpoints  for our first Phase 3 clinical trial include the

following:

(cid:127) assessment of response for the primary efficacy outcome of early clinical response (the FDA

primary endpoint) in the microITT population;

(cid:127) assessment of response in each treatment group with an investigator assessment of  clinical
response at TOC (the EMA primary endpoint) in the  microITT and ME-TOC populations;

In April 2016, we reached an agreement with the FDA  under the Special Protocol  Assessment

procedure to amend the design of our first Phase 3 clinical trial of lefamulin  for the  treatment of
CABP. The amendment to the SPA followed discussions with the FDA regarding  the design of  our
second  Phase 3 clinical trial of lefamulin  as well as discussions regarding the  overall Phase 3
development program for lefamulin for  the treatment  of  CABP. We  believe the design of the study
remains within the parameters set forth  in the  FDA Guidance  for  Industry Community—Acquired
Bacterial Pneumonia: Developing Drugs  for Treatment. Key amendments  to  the study include:

(cid:127) modify the non-inferiority margin of the primary FDA endpoint of early clinical response from

10% to 12.5%;

(cid:127) reduce the total number of patients to be enrolled in  the study from 740 to as low as 550 as  a

result of a revision of the non-inferiority  margin;

(cid:127) simplify the treatment regimens; and

(cid:127) increase the duration of therapy from a  minimum of five days to a minimum of seven days.

In December 2016, we reached an enrollment target  of  60% in our  first Phase 3 clinical trial, and
in February 2017, we received a recommendation from  an independent  interim analysis committee  that
we continue the trial with no adjustment  to  its  sample size.

Second Phase 3 Clinical Trial

Our second Phase 3 clinical trial of lefamulin for  the treatment  of CABP is a multi-center,

randomized, controlled, double-blind study comparing oral  lefamulin to moxifloxacin, a fluoroquinolone
antibiotic. This trial is designed to assess  the non-inferiority  of  oral lefamulin compared  to
moxifloxacin. We expect the study population will include male  and female patients of  at least 18  years
of age. We are targeting the enrollment of approximately 738 patients  in this  trial.

Lefamulin will be dosed orally at 600mg every 12 hours. The comparator  drug moxifloxacin will be

dosed according to approved labeling at  400 mg daily. All  medications  will be administered according
to a double-blind and double-dummy design.

All patients enrolled in this trial will  be  classified as PORT  severity of at least 2 and no greater
than 4 on a scale of 1 to 5 which corresponds  to  moderate disease. Patients  who have previously taken
no more than one dose of a short acting,  potentially effective antibiotic for the treatment of the current
CABP episode within 24 hours of receiving the first  dose of study medication will be allowed to
participate in the trial but will comprise only up to 25% of the  total intent to treat,  or ITT, population.
Investigators will obtain baseline Gram’s stain and  culture of  suitable specimens from the  site of
infection. Patients will be treated for  five  days with lefamulin or for seven  days with moxifloxacin.  We
will assess patients between 72 and 120 hours from  the start  of treatment,  at the  end of treatment,  or
EOT, within 48 hours of administration  of  the final dose  of  study medication,  at a  TOC  visit between
five and ten days after administration of  the final dose of study medication and at a telephone
follow-up 30 days after administration of the first dose of study medication.

We  will evaluate the following patient  subsets:

study medication;

(cid:127) a MITT population consisting of all randomized subjects who  receive any amount of study drug;

(cid:127) a microbiologically evaluable, or ME, population consisting of all subjects who meet the  criteria
for inclusion in both the microITT, CE-EOT  and  ME-EOT populations or  the CE-TOC and
ME-TOC populations.

The primary efficacy endpoint for the trial for the FDA is the proportion  of  patients in the ITT
population for each lefamulin treatment  group and  the moxifloxacin treatment  group who are  alive,
have improvement in at least two of the  four cardinal symptoms of CABP as outlined in the  current
FDA guidance, have no worsening in  any of the four cardinal symptoms  of CABP  and have  not
received a concomitant antibiotic for the  treatment of CABP up  through 120 hours after  the first dose
of lefamulin. This endpoint is also referred to as early clinical response.

The primary efficacy endpoint for the EMA  is the clinical success rate at the TOC visit  for

lefamulin in both the CE and MITT populations compared to moxifloxacin. Clinical success is based  on
the investigator’s assessment that a patient  has clinically responded to lefamulin,  which means that the
patient has complete resolution or significant improvement of all local and systemic  signs and
symptoms of infection such that no additional antibiotic  treatment is administered for the treatment  of
the current episode of CABP.

Key secondary efficacy and exploratory  endpoints for our second  Phase 3 clinical trial include  the

following:

(cid:127) assessment of response for the primary efficacy outcome of early clinical  response  (the FDA

primary endpoint) in the microITT population;

(cid:127) assessment of response in each treatment group with an investigator assessment  of  clinical
response at TOC (the EMA primary endpoint)  in the microITT and ME-TOC populations;

(cid:127) assessment of the microbiological response  by  pathogen  for the microITT and ME-TOC

populations at TOC; and

(cid:127) assessment of all-cause mortality through day 28  in the ITT population.

comparison therapy because vancomcyin  is one of the  antibiotics recommended  by  IDSA  guidelines for
the treatment of ABSSSI.

Trial Design

We  enrolled 210 hospitalized patients with ABSSSI in the trial.  The  study population  included

male and female patients of at least  18  years of age and documented ABSSSI  known  or suspected to
have been caused by a Gram-positive pathogen. Patients  must  have exhibited two signs  of systemic
inflammation or evidence of a significant underlying systemic or local medical condition at the time of
enrollment and have required IV antibiotic therapy for the treatment of the ABSSSI.

We  randomized patients on a 1:1:1 basis  to  three treatment  groups to receive:

(cid:127) 100 mg of IV lefamulin every 12 hours;

(cid:127) 150 mg of IV lefamulin every 12 hours; or

(cid:127) 1,000 mg of IV vancomycin every 12  hours  or otherwise dosed  as local  practice  dictated based

upon a patient’s kidney function.

Investigators obtained baseline Gram’s stain and culture of suitable  specimens from the  site of
infection. We treated patients for a minimum  of  five  days and a maximum of  14 days. We assessed
patients on day 3, at the end of treatment within 24 hours of  administration of the  final dose of study
medication, at a TOC visit between seven  and 14 days after administration of the final dose of study
medication and at telephone follow-up at 30  days  after the last dose  of  study medication was
administered.

The trial protocol specified the following four patient subsets for evaluation:

(cid:127) an ITT population consisting of all randomized patients  who received at least one dose of study

medication;

(cid:127) an MITT population consisting of  all patients in the  ITT population  who had a documented

Gram-positive pathogen culture at baseline;

(cid:127) a CE population consisting of patients who had  a confirmed  diagnosis  of ABSSSI, received study
medication as randomized, received at least 80%  of  expected study medication, did  not  receive
any potentially concomitant antibiotics, were  not  unblinded and had  a  response assessment  at
the TOC visit; and

(cid:127) an ME population consisting of patients in the  CE population who  had a  documented

Gram-positive pathogen culture at baseline.

The primary efficacy endpoint of the trial was the  clinical success rate  at  the  TOC  visit for the 100

mg and 150 mg dosage forms of IV lefamulin in  both  the CE  and MITT populations compared to
vancomycin. Clinical success was defined as complete resolution or significant improvement of all local
and systemic signs and symptoms of infection with no  further  systemic antibiotic treatment required.

Key secondary efficacy and exploratory endpoints  of  the trial included the following:

(cid:127) assessment of clinical response in the ITT and ME  populations;

(cid:127) comparison of clinical response by pathogen and microbiological response by pathogen;

(cid:127) change in lesion size and resolution of fever; and

(cid:127) clinical response at day 3.

Evaluation of pharmacokinetic parameters in  the trial included  analysis of  plasma  concentrations
of lefamulin in blood samples after the  first dose on  day  1, on day 5  and  on  the final  treatment day.

Three of the 210 patients enrolled in the trial did  not  receive study  medication, resulting  in 207

patients in the ITT population. Of the  patients in the  ITT population,  105 patients had cellulitis
(50.7%), 64 patients had abscess with  cellulitis (30.9%), 37  patients had  wound infections  (17.9%) and
one patient had burns (0.5%). At least one pathogen responsible for ABSSSI was  identified in 155
patients. Of these patients, 152 patients (97.4%) had  at least  one  Gram-positive pathogen, comprising
the MITT population. The most frequent Gram-positive  pathogen  was S. aureus, with the majority,
69.1% of patients in the MITT population, being methicillin-resistant strains. The CE population
included 165 patients. The ME population included  129 patients.

Patient demographics were similar across all three treatment groups, except for the presence of
diabetes at baseline. The 150 mg lefamulin  dose group  included a slightly  greater proportion of patients
with diabetes than the other treatment groups.

Efficacy

In the trial, the patients in the lefamulin treatment groups  experienced  a similar  clinical success
rate at the TOC visit as patients in the vancomycin treatment  group, in each  of  the ITT, MITT, CE and
ME patient subsets. These results are  summarized in  the table below. In addition, the clinical success
rate in the trial was high for important subgroups of patients based on  factors such  as primary infection
type and diabetes mellitus status. The  table below also  shows the  95%  confidence interval, a  statistical
determination that demonstrates the  range  of  possible differences in the  point estimate of success  that
will arise 95% of the time that the endpoint is measured. However, this trial was  not  statistically
powered to determine differences between treatment groups.  The  sample size chosen was  to  provide
clinically meaningful information on efficacy, safety and tolerability.  In  this table  and other tables
appearing below, the abbreviation ‘‘N’’ refers  to  the number  of  patients or subjects in each group  or
subgroup.

A list of all pathogens identified at baseline along with the  corresponding eradication  rate by

treatment group in the MITT patient subset is presented in  the table below. Microbiological
eradication rate was defined as the proportion of patients with  a microbiological outcome of
eradication or presumed eradication based on cultures from both the primary infection  site and  blood
cultures. Patients with indeterminate or  missing clinical responses were considered  non-eradication.
Overall, in the MITT population, microbiological success was achieved in  40 of 50  patients  (80.0%) in
the lefamulin 100 mg group, 43 of 51  patients  (84.3%) in the lefamulin 150  mg  group, and  42 of 51
patients (82.4%) in the vancomycin group. We did  not  observe development of decreased susceptibility
to lefamulin or vancomycin during the trial.  In  this table,  the abbreviation  ‘‘n’’ refers to the  number of
patients who had a microbiological outcome of  eradication or presumed eradication  for each specified
pathogen.

We  evaluated the clinical success of lefamulin against  S. aureus, which is the most commonly
identified cause of ABSSSI. The clinical success  rate against a variety of subsets of S. aureus based on
in vitro antibiotic susceptibility (methicillin-resistance),  as well as  the presence or absence of the
virulence factors PVL-positivity or USA300, are clinically important, as limited therapeutic options exist
to treat such infection. A summary of the clinical success  rate against S. aureus is presented in the table

The mean duration of exposure to study medication  treatment was approximately seven days for  all

groups, and almost 70% of patients completed  therapy within that time.

Safety and tolerability

Lefamulin was well tolerated in this trial. No patient  in the trial  suffered  any  serious adverse
events that were found to be related to lefamulin, and no  patient  in the trial died. The percentage of
patients in the trial arms that experienced  any  treatment emergent adverse  event were  similar across
treatment groups:  71.4% in the lefamulin 100  mg  group, 69.0% in  the lefamulin 150 mg group  and
74.2% in the vancomycin group. Most of the  treatment emergent  adverse  events were  mild to moderate
in severity. The table below shows the  adverse  events experienced by  patients  in the trial that were
assessed by the investigator as possibly  or  probably related to study medication.

The incidences of pain, tenderness, itching, erythema, swelling and thrombosis  at the infusion site
were higher for the lefamulin 100 mg group and  the lefamulin 150  mg group than  for the  vancomycin
group. The majority of these local tolerability symptoms were mild in  severity. No patient had  a severe
local tolerability issue of erythema or  swelling. No patient had  a  local  tolerability issue of necrosis.
When summarized on an infusion basis,  the proportions of infusions with local tolerability  events were
similar for the treatment groups.

Four patients discontinued study medication following a drug-related  adverse  event: one patient
(1.4%) in the lefamulin 100 mg group  (events of hyperhidrosis, vomiting and headache), two patients
(2.8%) in the lefamulin 150 mg group  (infusion site pain in one patient and  dyspnea in the  other), and
one patient (1.5%) in the vancomycin  group (drug eruption).

Because the potential for mild effect  on ECG measurements was observed in preclinical studies,
we have continued to assess this potential in all human clinical trials we have conducted. In  the Phase 2
clinical trial, no change in ECG measurements  was  considered to be of clinical significance, and no
drug-related cardiovascular adverse event  was reported.  Both lefamulin  and  vancomycin treatment were
associated with a small increase in the  QT interval. The QT interval  is a measure of the heart’s
electrical cycle, with a lengthened QT  interval representing a  marker  for  potential  ventricular
arrhythmia. We plan to continue to evaluate  the effect of lefamulin on the QT interval in our Phase 3
clinical trials of lefamulin for CABP.

Pharmacokinetics

The table below summarizes selected  pharmacokinetic parameters we  obtained  from

pharmacokinetic sampling in the trial.  Cmax  refers to the maximum  observed peak blood plasma
concentration of study medication. AUC refers to the  area under  the curve in a  plot of concentration
of study medication in blood plasma  over time, representing total drug exposure over time. In this
table, the abbreviation ‘‘SD’’ refers to the  standard deviation of the results. Standard deviation is a
statistical measure used to quantify the  amount of variation  within a set of data values. A standard
deviation  close to zero indicates that  the  data points do not vary greatly  from  the mean, while  a high
standard deviation indicates that the  data points are spread over  a wider range of values.

Efficacy for the pleuromutilin class of antibiotics is related to the ratio of  total  drug exposure over

time, measured by the AUC, to minimum  inhibitory concentration, or MIC.  MIC is  the minimum
concentration of an antibiotic needed to inhibit growth of an organism. The plasma concentration  data
obtained from the Phase 2 clinical trial are the  first  data that  describe how lefamulin is absorbed,
distributed around the body, metabolized and eliminated in patients suffering from  an infection.

Phase 1 Clinical Development

We  conducted seventeen Phase 1 clinical trials of lefamulin in Austria, Germany, the United States

and the United Kingdom between 2009  and 2015.  In  these trials, we exposed 321  healthy subjects,
including elderly subjects 65 years of  age or older, to single or multiple doses of IV or oral lefamulin.
The objectives of our Phase 1 clinical trial program have been to understand the  absorption and
distribution of lefamulin in the blood and target tissues, evaluate the metabolism and  elimination route
of lefamulin and obtain safety and tolerability  data  to  help predict safe and effective  doses of  lefamulin
for the treatment of patients. We have additional Phase  1 clinical  trials ongoing, including drug
interaction studies as well as studies  in  special populations (hepatic and renally impaired subjects).

Pharmacokinetic Overview

Our key observations from our Phase  1 clinical  trials include the  following:

(cid:127) lefamulin is rapidly absorbed and distributed throughout the  body after  either IV or oral

administration;

(cid:127) lefamulin achieves therapeutic concentrations in a variety of  target tissues, including the lung,

skin and soft tissue;

(cid:127) lefamulin has a half-life between 8.6 and 11.8  hours,  which enables  a  twice daily regimen, and is

eliminated primarily through non-renal  pathways;

(cid:127) lefamulin is a weak inhibitor of some liver enzymes, but we do  not expect  to  need  to  adjust the

dose of lefamulin when it is co-administered  with other  drugs;

(cid:127) no statistically significant effects of  age,  gender, body  weight or height, body mass index  or other

demographics on the pharmacokinetic parameters  of  lefamulin;

(cid:127) the absolute oral bioavailability of a 600  mg  immediate  release, or IR, tablet formulation of
lefamulin were 25.8% in the fasted and 21% in the  fed condition  in healthy  subjects; and

(cid:127) in the assessment of relative bioavailability,  bioequivalence was  demonstrated for  the fasted IR
tablet and the IV dose, exposure was slightly lower for the  fed IR tablet than  the IV dose.

Absorption

Lefamulin is absorbed rapidly after oral dosing with or without food. In our  Phase 1  clinical trials,

steady state blood levels were achieved  after two days  of  dosing every  12 hours, irrespective of the
route of administration, and the variability after oral  dosing  was  similar to the  variability  after IV
infusion. Because the ability of pleuromutilin antibiotics to  kill bacteria is dependent  on the  AUC, or
total lefamulin exposure over time, to  MIC ratio,  and  IV  doses  of  150 mg  every  12 hours and oral
doses of  600 mg every 12 hours achieve similar AUCs,  we believe that both regimens  are capable of
providing a similar therapeutic benefit.

Distribution

Following IV infusion, lefamulin is rapidly distributed throughout the  body over  approximately
30 minutes. We have observed rapid  distribution  of  lefamulin into tissues, including the skin and ELF
of the lung. In CABP, the lung is the target organ where pathogens  replicate and cause inflammation
that results in mucous production, cough  and shortness of breath.  Therefore, in 2010,  we conducted a
Phase 1 clinical trial to assess the pharmacokinetics of lefamulin in 12 healthy subjects. After a  single
IV administration of 150 mg of lefamulin  over 60 minutes,  we  performed a  bronchoalveolar lavage, or
BAL, a medical procedure to collect fluid from the lung. We performed  BAL analyses in  groups of
three subjects at 1, 2, 4 and 8 hours after  the start of the  lefamulin infusion  and measured lefamulin

concentrations in the ELF, the muscle  tissue,  soft tissue and blood plasma. In this trial, the exposure of
free lefamulin, or the amount of lefamulin not bound to proteins and therefore available to inhibit
bacterial growth, achieved in the ELF  was approximately six times  greater than free lefamulin  exposure
observed  in blood plasma.

Metabolism

The average half-life, or the time it takes  the body  to  eliminate one-half of the concentration  of

lefamulin present, is 9 to 12 hours. The major route  lefamulin is  eliminated from the body is  the
gastrointestinal tract, with limited metabolism of lefamulin occurring mainly  through a liver and  gut
wall enzyme called CYP3A4, which is  responsible for  the metabolism of  a  wide variety  of  medication.
We  have identified only one metabolite,  called BC-8041, as exceeding  10% of lefamulin concentrations
in the plasma and only when lefamulin  was given  orally. None of the metabolites of lefamulin have any
antibacterial properties.

Drug Interaction Potential

We  continue to perform studies recommended by regulatory authorities to assess the drug-drug

interaction potential of new drug products, including the assessment of the impact of potent
P-glycoprotein and CYP3A4 inducers on the  PK of lefamulin, and the impact of  lefamulin  on drugs
metabolized via CYP3A4.

Safety and Tolerability

Lefamulin has been well tolerated in all  Phase 1  trials completed to date. We did not observe any
systemic adverse events of clinical concern  or any drug-related serious  adverse events in these trials. In
addition, we did not observe any changes  of clinical  concern in laboratory safety parameters or vital
signs in any subject in any of the trials. The most  commonly observed adverse  effects with oral
administration of lefamulin were related to the  gastrointestinal tract, including  nausea and  abdominal
discomfort, while the most commonly  observed adverse effects  related to IV administration were
related to irritation at the infusion site. In addition, lefamulin produced  a transient, predictable  and
reproducible prolongation of the QT interval  based on  the maximum concentration  of  the drug in the
blood plasma. At therapeutic doses, we expect that the  drug  will not  produce large  effects on  the QT
interval that would be of clinical relevance.  We  did not observe  any drug-related  cardiac  adverse  events,
such as increase in ectopic ventricular  activity or  other cardiac arrhythmia, or clinically relevant ECG
findings during the conduct of any of  our Phase 1  or Phase  2 clinical  trials.

Intravenous Formulation

We  have administered IV lefamulin as single and repeat doses every 12  hours  for up to 14 days.
The most frequently reported adverse events in our Phase 1 clinical trials were pain or erythema at the
site of the IV infusion. To further assess  local tolerability, we conducted  a Phase  1 clinical  trial in 2013
to evaluate the local tolerability of two  different IV formulations of lefamulin dosed every twelve hours
for 7.5 days. In this trial, we compared lefamulin  infusions given in normal saline  solution, a  sterile
sodium chloride solution commonly used to administer  IV medications, with lefamulin infusions given
in a sterile saline solution buffered by a citrate  salt that adjusted the pH, or  level of acidity, of the
solution. We enrolled 60 healthy subjects in the trial,  of which 25 received the normal  saline solution,
25 received the citrate buffered solution and  ten received a matching placebo  solution.  Although we did
not observe any difference between treatment arms over  the first three days of study infusions, over  the
entire treatment period, the incidence of  local pain or redness of at least moderate severity was
statistically higher with lefamulin in the  saline solution (84%), as  compared to the citrate  buffered
infusions (36%) or placebo (10%). There  was  no statistical difference  between  citrate buffered

infusions and placebo at any time period  during the  trial. As  a  result, we  will  administer  lefamulin  IV
infusions in a citrate buffered saline solution in our Phase 3 clinical trials for CABP.

Oral Formulation

Initially, we administered lefamulin orally in capsules  as single and repeat  doses for up  to  five
days. Oral administration of lefamulin  was generally  well tolerated with infrequent reports  of mild
gastrointestinal findings, such as nausea, abdominal  pain  and  diarrhea. We subsequently  developed  600
mg tablets that we have investigated in  single  and repeat dose studies. These tablets  have been well
tolerated and shown favorable pharmacokinetics. We  will utilize the 600 mg tablets in our Phase 3
clinical trials.

Electrocardiogram Measurements

In our Phase 1 clinical trials, lefamulin  was associated with a Cmax-dependent,  transient,
predictable, reversible and reproducible prolongation of the  QT  interval. We have  closely monitored
ECG measurements in all our trials. We did not observe  any drug-related cardiac adverse events, such
as increase in ectopic ventricular activity or other  cardiac arrhythmia,  or  clinically relevant  ECG
findings during the conduct of any of  our Phase 1  clinical  trials. None of the  ECG stopping  criteria
defined in the trial protocols was reached in any clinical  trial. We plan  to  continue to assess the  effects
of lefamulin on the QT interval in our planned clinical  trials.

Preclinical Development

In our preclinical studies, administration of  lefamulin  was well tolerated in a variety of animal
models. Lefamulin was active against  a broad  range of bacteria,  suggesting  possible  use as  monotherapy
for CABP with a low propensity for development of bacterial resistance.

Nonclinical Safety

In several preclinical safety and toxicity  studies, including repeat dose  toxicity, local tolerance,
genotoxicity, development and reproductive  toxicity, and  safety pharmacology testing in both rodent and
non-rodent species, lefamulin was safe  and well  tolerated. When we  treated rats  or monkeys  for up to
four  weeks with either oral or IV lefamulin, we did not identify  any specific target organ toxicity.
Lefamulin was not associated with genetic damage, effects  on fertility or birth defects.  We are  also
conducting longer term toxicity studies  in a rodent and  a non-rodent  species.

Antimicrobial Spectrum of Lefamulin

We  have extensively studied the antimicrobial in vitro activity of lefamulin against a variety of
respiratory, or aerobic, and non-respiratory, or anaerobic, bacterial pathogens  representing more than
17,700 clinical isolates collected from  patients worldwide. A summary of our observations is presented
in the table below. MIC90 indicates the concentration of drug that  inhibits  90% of the pathogens in
vitro, while MIC50 indicates the concentration of drug that  inhibits  50% of the pathogens in vitro.

The tables below compare the in vitro activity of lefamulin and various antibiotics  for CABP and
ABSSSI pathogens against various strains of bacteria, including those resistant to current antibiotics.
Unlike other  CABP antibiotics, such  as  ß-lactam/ß-lactamase inhibitor combinations,  glycopeptides and
oxazolidinones, lefamulin was active against the vast  majority  of  potential respiratory pathogens
collected in 2015. When an alternative antibiotic from  the same drug class  was  utilized,  it is footnoted
within the table and below.

Activity Against Resistant Strains and  Low  Propensity  for Development of  Bacterial  Resistance

When tested against bacterial organisms resistant to macrolides,  tetracyclines, quinolones,
trimethoprim/sulfamethoxazole, vancomycin, mupirocin or  ß-lactams,  we did not observe any cross-
resistance with lefamulin. Lefamulin displayed activity in vitro against drug-resistant N. gonorrhoeae,
VRE,  MRSA, multi-drug resistant S. pneumoniae, VISA/hVISA, erythromycin-resistant group A
Streptococcus species and clindamycin-resistant group B Streptococcus species, all of which are listed as
urgent, serious or concerning threats  by  the CDC. We utilized the interpretative criteria of the Clinical
and Laboratory Standards Institute, or CLSI, to categorize the in vitro activity of each comparator
against the organisms listed in the table  below  as sensitive (%S), intermediate (%I) or resistant (%R).
Bold and underlined data indicate resistance according  to  CLSI criteria.

Lefamulin has shown low potential for resistance  development in vitro, which we believe is the
result of the specific interaction with a binding site  on the ribosome. Repeated exposure  to  low levels
of lefamulin in laboratory tests resulted  in a slow and step-wise development  of  resistance  in S. aureus,
Streptococcus species, and E. faecium. We believe that lefamulin’s low potential for resistance is further
supported by the fact that we observed isolates with consistently low MICs during our Phase 2 clinical
trial in ABSSSI and that, despite the use of  pleuromutilins in  veterinary medicine for decades, the
incidence of pleuromutilin-resistant isolates remains relatively  low. Cross-resistance between lefamulin
and other classes of antibiotics has also  been rarely  observed in our  completed studies to date. Based
on global surveillance studies in more  than 13,600 clinical isolates, fewer than  0.02% of isolates  contain
mutations responsible for methylating,  or  chemically modifying, the interaction between lefamulin  and
other protein synthesis inhibiting antibiotics. One example of this mutation is called cfr mutation, which
when present has resulted in  observed  elevations  in the MIC90 to lefamulin as well as other antibiotics,
such as chloramphenicol and linezolid.

Activity in Animals

We  evaluated the activity of lefamulin in a number  of murine, or  mouse,  infection models,

including pneumonia, septicemia, and thigh infection  models. In these models, lefamulin was efficacious
against S. pneumoniae (penicillin- and macrolide-resistant) and S. aureus (methicillin-susceptible, or
MSSA, and MRSA). Lefamulin was active  against serious lung  infections caused  by  clinically relevant
strains of S. pneumoniae or S. aureus. Investigations of the exposure levels in the  ELF  in the lungs of
mice showed rapid distribution of lefamulin into the  lung  compartment with penetration  rates  into  the

ELF of 12-fold compared to free plasma  concentration measured in the same  mice. We confirmed  this
result by whole-body imaging using radioactive labeled lefamulin.

Lefamulin also showed high intracellular activity and rapid accumulation in  macrophages,  or
immune cells that  are responsible for assisting in  clearing bacterial infections from  the lung  and other
body sites, (30- to  50-fold) dependent  on  the time of incubation and lefamulin concentration.
Azithromycin showed a 15- to 20-fold  accumulation in the same experiments. Furthermore,  the activity
of lefamulin was unaffected by lung surfactant,  a naturally occurring substance found in the  lung  that
has the ability to inactivate some antibiotics.

Concentrations of Lefamulin Predicted to  be Effective in Treating Lung  Infections

We  believe that results from preclinical analyses of concentrations  of lefamulin in  lung  tissue

indicate the potential for favorable outcomes in CABP patients treated with  lefamulin. We have
provided and discussed with regulatory authorities,  including the  FDA, these preclinical results and  the
safety and efficacy of lefamulin observed in subjects  and patients  with ABSSSI. Based  on these
discussions, we intend to evaluate the efficacy  and safety of lefamulin in our Phase 3 clinical trials for
CABP. We used results obtained from pharmacokinetic analyses  of lefamulin concentrations over  time
and pharmacodynamic analyses of the  relationship of concentrations of lefamulin and  effect, also called
PK-PD, to determine the predicted likelihood of  achieving lefamulin  concentrations in  the lung  that
would be effective at inhibiting the growth  of common bacterial causes of CABP. This assessment
utilized a population pharmacokinetic  model that  describes  the behavior of lefamulin in blood  plasma
in subjects and patients with infection,  the ELF concentrations  achieved  in healthy volunteers, in vitro
MIC targets for the most common causative pathogens associated with CABP  accrued from a robust,
global  in vitro surveillance library, and mathematical  simulations replicating thousands of scenarios that
could represent the many possible combinations of lefamulin  concentrations achieved and  the MIC
required to inhibit bacterial growth. Based on  these  assessments, we  believe that a lefamulin regimen of
either 150 mg administered by IV every 12 hours or 600  mg administered orally  every  12 hours has a
probability of 96% or more to achieve  concentrations in  the ELF  that would inhibit the growth of  both
S. pneumoniae and S. aureus.

Based on all of the available evidence, including lefamulin’s  in vitro activity, clinical

pharmacokinetics and tissue penetration, and safety  and efficacy  observed in our Phase 2 clinical trial
for ABSSSI, we are using a dose of 150  mg IV  or 600 mg orally every  12 hours in our Phase 3 clinical
trials of lefamulin for CABP.

Additional Indications for Lefamulin

ABSSSI

Acute bacterial skin and skin structure infections  are common and are characterized by a  wide

range of disease presentations. Gram-positive bacteria,  in particular S. aureus, S. pyogenes and S.
agalactiae, are the most common pathogens in ABSSSI. The rising frequency of ABSSSI caused  by
MRSA  and the significant increase in the  occurrence of CA-MRSA infections over the  past 15 years is
an increasing concern. According to IDSA Skin and Skin Structure Infection guidelines 2014,  in most
U.S. cities, CA-MRSA is now the most  common pathogen cultured from patients with ABSSSI in
emergency departments. While the current standard of  care  for MRSA infections is vancomycin, the
efficacy of this treatment is being compromised  because of decreased susceptibility,  or even  resistance,
of S. aureus to vancomycin. In addition, although linezolid is  approved for ABSSSI due to MRSA, its
use has been limited because of potential  adverse  events and drug-drug  interactions with commonly
prescribed concomitant medications such as antidepressants.

The emerging incidence of resistance  to multiple  antibiotics in pathogens makes ABSSSI
increasingly difficult to treat and results  in a need for alternate therapies.  Based on our preclinical
studies and clinical trials, we believe that  lefamulin has  potential to treat ABSSSI. In preclinical  studies,
lefamulin has shown  in vitro antibacterial activity against the most relevant pathogens  responsible for
ABSSSI including S. aureus (MSSA, MRSA, and CA-MRSA), S. pyogenes, and S. agalactiae. In our
Phase 2 clinical trial evaluating the safety  and  efficacy of two different doses of the IV  formulation of
lefamulin administered over five to 14 days compared to vancomycin in patients with ABSSSI, the
clinical success rate at test of cure for lefamulin  was  similar to that of vancomycin. We have discussed
the design of a proposed Phase 3 clinical  trial to evaluate  the efficacy  and safety  of lefamulin for  the
treatment of ABSSSI with the FDA and several E.U. regulatory  authorities.

Pediatric Indications

Not unlike treatment of infectious diseases in  adults, the  management  of  pediatric infections has

become  more difficult due to the continuing rise in resistance in bacteria.  Further complicating
antimicrobial selection in the pediatric population is the need for agents to be very well tolerated  and
available in a final dosage form that  can be easily  administered to children. Based upon the in vitro
antimicrobial spectrum of activity, along with the safety  profile observed to date, we  believe lefamulin is
appropriate for evaluation for the treatment of a  variety  of pediatric  infections, including those
affecting the respiratory tract and skin  and skin  structure. We have begun pediatric formulation
development activities to support clinical trials in the pediatric  population.

HABP/VABP

One  of the major  causative organisms  of hospital-acquired bacterial pneumonia and  ventilator-
associated bacterial pneumonia is  S. aureus, including MRSA. We are evaluating  whether  to  investigate
the utility of lefamulin in the  treatment  of HABP and VABP. We have deferred commencement of a
previously planned Phase 1 clinical trial  of  lefamulin for VABP in order to focus our efforts and our
resources on our ongoing Phase 3 clinical  trials of lefamulin for CABP.

STIs

Urethritis and cervicitis caused by N. gonorrhoeae, C. trachomatis or M. genitalium are frequently

occurring sexually transmitted infections in the United States and Europe. Left untreated, these
infections can cause serious health problems,  particularly in women,  including chronic pelvic  pain,
life-threatening ectopic pregnancy and  infertility. Resistance in  these  organisms to the  most commonly
prescribed antibacterial treatments poses  a serious public  health threat.  For example, the  CDC
estimates that 30% of the clinical isolates  of N. gonorrhoeae are resistant to at least one currently
available antibiotic.

In preclinical studies, lefamulin has shown  high potency  against N. gonorrhoeae, C. trachomatis and

M. genitalium, including strains  resistant to currently available antibacterial  agents. As a result, we  are
actively assessing a non-clinical and clinical development  plan to support the development  of lefamulin
as a first-line treatment for urethritis,  cervicitis and pelvic inflammatory disease.

Osteomyelitis

The incidence of osteomyelitis, which is  an infection  of  the  bone, is increasing. The most common

causative organism is S. aureus. In the United States, the prevalence of  MRSA  in these cases ranges
from 33% to 55%. Up to 90% of cases of  hematogenous osteomyelitis,  most frequently in children, are
caused by S. aureus. We believe that lefamulin has the potential to be an  effective treatment option for
osteomyelitis. Lefamulin has shown substantial tissue penetration  and  activity against the  most common

date,  lefamulin will be well tolerated for  the long term use  necessary  for the  treatment of both adult
and pediatric patients with osteomyelitis. The current  standard of care  for  these  infections is  treatment
with vancomycin. We believe the ability to administer lefamulin  by either the IV  or oral route  would
provide a significant advantage over  agents,  such as vancomycin, that can only be administered  by  IV.

Prosthetic Joint Infections

Infection occurs in approximately 1% of joint replacement surgeries.  Although the  incidence of

infection has been decreasing, the total number of replacement operations has been rising, such that,
overall, there is increasing morbidity.  The majority of these infections  are caused  by  three organisms:
coagulase negative staphylococci, S. aureus (including MRSA) and streptococci, all organisms  that are
sensitive to lefamulin. The preferred treatment for joint infections with MRSA is  vancomycin, with
daptomycin and linezolid as alternatives.  Vancomycin  and  daptomycin are  administered only by IV for
this  indication, and linezolid has side effects that affect long  term use. We believe that lefamulin could
provide an alternative for both IV and oral therapy for  these infections cases.

BC-7013 (Topical)

BC-7013 is a semi-synthetic compound derived  from pleuromutilin with the potential to be

developed for the topical treatment of  Gram-postivie infections, including uSSSIs.

BC-7013 is highly active against key bacterial pathogens causing skin and  ocular  infections. The
MIC90 values for BC-7013 against MRSA  are  up to 20-fold lower than for mupirocin and 8-fold lower
than for retapamulin, an FDA-approved  topical pleuromutilin. Furthermore, BC-7013  has demonstrated
potent activity against Chlamydia trachomatis, the leading cause of blindness in the  world, and
Propionibacterium acnes, the causative agent of acne.

We observed activity in a superficial skin infection model  in mice infected with MRSA.  BC-7013
was well tolerated following intranasal  administration  of  an ointment formulation in a Phase 1 clinical
trial.

Pleuromutilin Molecule Platform

Our pleuromutilin research program is  based on our  large and  diverse proprietary  compound
library. We believe that our expertise  in the areas of medicinal  chemistry,  pharmacology  and toxicology
have  enabled targeted discovery of novel pleuromutilins through modification of side  chains and core
positions in the mutilin moiety. These modifications have resulted in  alterations in microbial activity,
ADME and toxicity of the semi-synthetic  molecules.

We are actively pursuing an in-house  discovery program  to sustain  our pipeline with future product
candidates. The aim of this program is the development of novel pleuromutilins with enhanced  affinity
for the bacterial ribosome directed at increasing the antimicrobial potency and broadening the
spectrum of activity to include rare strains with known mechanisms of resistance to the  pleuromutilin
class (e.g. cfr  or Vga mutants). We believe next generation pleuromutlins have  the potential to exhibit
improved antibacterial activity and a pharmacokinetic profile  that may  make  them well  suited for the
treatment of respiratory tract infections, acute/complicated  bacterial skin infections, sexually transmitted
infections and biothreat organisms.

Compounds in Other Antibiotic Classes

In addition to the pleuromutilin research  program, we  own a  ß-lactam library encompassing
approximately 2,000 novel broad spectrum  cephalosporins and approximately 150 novel ß-lactamase
inhibitor molecules. We own all rights  and hold one  active  patent  application  on file  covering
ß-lactamase inhibitors.

We  also own a library of approximately 200  acremonic  acid derivatives which inhibit bacterial
protein translation and have an antibacterial profile that covers primarily  Gram-positive bacteria, such
as S. aureus, MRSA and mupirocin-resistant strains, as well as ß-hemolytic streptococci (Streptococci
that are not S. pneumoniae or members of the Viridans family). The  first molecules in  this  series  also
displayed improved activity against isolates showing  resistance against fusidic acid and showed  no cross-
resistance with other classes of antibiotics tested.

The existing compound libraries of ß-lactam/ß-lactamase inhibitors  and acremonic acid  derivatives

represent an unrecognized portion of our pipeline. The current allocation of our funds and staff are
dedicated to advancing the pleuromutilin  compounds. Assessment of the ß-lactam/ß-lactamase inhibitors
and  acremonic acid derivatives compound  libraries will be dependent  upon additional funding.

Commercialization Strategy

We own  exclusive,  worldwide rights to  lefamulin. We expect  that our  initial target population for

lefamulin will consist of patients with moderate to severe CABP whose antibiotic treatment is hospital-
initiated. If lefamulin receives marketing approval from the FDA for  the treatment of  CABP, we plan
to pursue commercialization strategies that maximize the  value of lefamulin in  the United  States  with
our own targeted hospital sales and marketing organization  that we plan to establish. We believe that
we will be able to  effectively communicate lefamulin’s differentiating characteristics, positioning and key
attributes to clinicians, hospital pharmacists and managed  care organizations, with  the goal of
establishing favorable formulary status  for lefamulin. Based on our market research, we  believe
lefamulin has a novel position supporting adoption in the United States  for adult CABP  hospital-
initated treatments, which we believe represents a significant commercial opportunity. Additionally, we
believe that our plans for a targeted  hospital-focused sales  force should allow us to address on  our own
the hospital-initiated treatment market for  CABP in  the United  States. We plan to continue our
pre-commercialization activities to prepare  for a  potential  commercial launch of lefamulin,  subject to
marketing approval in the United States. If lefamulin  receives marketing  approval outside of the
United States for the treatment of CABP, we expect  to  utilize a variety of types of collaboration,
distribution and other marketing arrangements with  one or more third  parties to commercialize
lefamulin in such markets.

Along with additional market research,  we  believe that  medical  education  will be a  key  component

of our commercialization efforts and, following potential commercial  launch, plan  to  invest  in these
activities to maximize the commercial potential of lefamulin. With a targeted initial prescribing base
predominantly in the hospital setting, we expect  that a targeted hospital sales and marketing
organization would be relatively smaller  than  competitors who  are focused on both the hospital and
community prescribing base. We believe that lefamulin’s novel mechanism of action,  status as the only
member of a new class of systemically  administered pleuromutilins and anticipated clinical profile will
support its potential inclusion on formularies and in  local  and national  treatment guidelines, subject to
and  following marketing approval.

We plan to evaluate the merits of entering into collaboration agreements  with other

pharmaceutical or biotechnology companies that  may contribute to our ability to efficiently  advance  our
product candidates, build our product  pipeline and concurrently advance a  range of research and
development programs for a variety of  indications outside the United  States.

Manufacturing

We do not own or operate, and currently  have no plans to establish, manufacturing  facilities  for
the production of clinical or commercial quantities  of lefamulin, or any of the  other compounds that we
are evaluating in our discovery program. We currently rely, and expect to continue to rely, on third
parties for the manufacture of lefamulin and  any further products that we may develop. We have

significant in-house knowledge and experience in  the relevant  chemistry associated with our  drug
candidate and use these internal resources, alongside  third-party consultants, to manage  our
manufacturing contractors.

We  have engaged a limited number of  third-party manufacturers to provide  all  of  our  raw
materials, drug substance and finished product  for  use in  clinical  trials.  The active pharmaceutical
ingredients, or API, and drug products  have  been produced under master service contracts and  specific
work orders from these manufacturers  pursuant to agreements  that include specific  supply timelines
and volume and quality expectations.  We choose the third-party manufacturers of the drug substance
based on the volume required and the regulatory requirements  at  the relevant stage  of development.
All lots of drug substance and drug products used in clinical trials  are manufactured under current
good manufacturing practices. Separate third-party  manufacturers  have been responsible for  fill and
finish  services, and for labeling and shipment of the  final  drug product to the clinical trial sites.

We  do not currently have long-term agreements with  any  of  these third parties. We also do not
have any current contractual relationships  for the manufacture of commercial supplies  of  lefamulin if  it
receives marketing approval. We intend to enter into agreements with suitable third-party  contract
manufacturers for the commercial production of this product  pending potential  regulatory approval.

Our product candidate is a semi-synthetic organic compound of low molecular  weight.  The
pleuromutilin core of the molecule is  produced by  fermentation and is manufactured on a  significant
scale by various manufacturers. We have  selected  the compound based on efficacy and safety, although
it is also associated with reasonable cost  of goods,  ready availability  of  starting materials and ease  of
synthesis. The production of lefamulin  has  been carried out  at  a  significant scale  and we believe the
synthetic route to lefamulin is amenable to further scale-up. The synthetic route  does not require
unusual, or specialized, equipment in the  manufacturing process. Therefore, if any  of the future  drug
substance manufacturers were to become  unavailable for any reason, we believe there are  a number  of
potential replacements, although delays may be incurred  in identifying and qualifying  such
replacements.

Competition

The biotechnology and pharmaceutical industries are characterized by  rapidly advancing

technologies, intense competition and a  strong  emphasis on proprietary  products.  While  we believe  that
our  technologies, knowledge, experience  and scientific resources provide  us with competitive
advantages, we face potential competition  from many different sources, including major  pharmaceutical,
specialty pharmaceutical and biotechnology companies,  academic institutions, government agencies and
private  and public research institutions. Any product candidates  that we successfully develop and
commercialize will compete with existing  therapies and new therapies  that  may become available in  the
future.

Many of our competitors may 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. These competitors also  compete
with us in recruiting and retaining qualified scientific and  management personnel and  establishing
clinical trial sites and patient registration  for clinical  trials, as well  as in  acquiring  technologies
complementary to, or necessary for, our  programs. Smaller or early stage  companies may  also prove to
be significant competitors, particularly  through collaborative  arrangements with  large and  established
companies.

Our commercial opportunity could be reduced  or eliminated  if our competitors  develop  and
commercialize products 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 marketing approvals for their  products  more rapidly than we 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 because in  some cases  insurers  or other
third-party payors seek to encourage the  use of generic products.  This may have the effect of  making
branded products less attractive, from a  cost perspective, to buyers. We expect that if  lefamulin is
approved for CABP, it will be priced  at  a  significant premium over competitive generic  products. This
may make it difficult for us to replace existing therapies  with lefamulin.

The key competitive factors affecting the  success of our product candidates are likely  to  be  their
efficacy, safety, convenience, price and the availability of  coverage and reimbursement from government
and other third-party payors.

Currently, the treatment of CABP is dominated  by  generic products. For  hospitalized  patients,
combination therapy is frequently used.  Many currently approved drugs  are well established therapies
and are widely used by physicians, patients and third-party payors. We also are aware of various drugs
under development for the treatment of  CABP, including solithromycin (NDA filed by Cempra  Inc. and
complete response letter issued by the FDA in December 2016),  omadacycline  (under Phase  3 clinical
development by Paratek Pharmaceuticals Inc.) and delafloxacin (under  Phase 3  clinical development  by
Melinta Therapeutics Inc.).

Intellectual Property

Our success depends in large part on our  ability to obtain and maintain proprietary  protection for
our  product candidates, technology and know-how, to operate without infringing the  proprietary rights
of others and to prevent others from infringing our  proprietary  rights. We strive to protect the
proprietary technology that we believe  is  important to our  business by, among other methods, seeking
and maintaining patents, where available,  that are intended to cover  our product candidates,
compositions and formulations, their methods of use and processes for their manufacture and any other
inventions that are commercially important to the development of our  business.  We  also rely on  trade
secrets, know-how, continuing technological innovation  and in-licensing  opportunities to develop and
maintain our proprietary and competitive  position.

As of February 10, 2017, we owned 21 different families of patents and patent applications,
including 20 families directed to the  various pleuromutilin derivatives as compositions  of  matter,
processes for their manufacture, and  their  use in pharmaceutical compositions  and methods of treating
disease. The remaining family is directed  to  ß-lactamase inhibitors. Our  patent  portfolio  includes 22
issued U.S. patents, 20 granted European  patents and 16 granted Japanese patents, as well  as patents
in other jurisdictions. We also have pending  patent  applications in the United States, Europe, Japan
and other countries and regions, including Asia, Australia, Eastern  Europe,  and South  America,
including notably Canada, Brazil, China, Israel, India and Taiwan among others.

All of these patents and patent applications  are assigned solely to us and  were  either originally

filed by us or originally filed by Sandoz and  subsequently assigned to us.

As of February 10, 2017, our lead product candidate,  lefamulin, was protected by the  following  six

patent families:

(cid:127) The first patent family includes patents and  applications with claims directed to generic  classes
of compounds that include lefamulin  and/or their use in the treatment of microbial infections.
This family includes issued patents in the United  States, Europe and Japan,  as well as  issued
patents in 10 other jurisdictions. The standard  term for patents  in this family expires  in 2021.

(cid:127) The second patent family includes patents and applications with claims that specifically recite

lefamulin and/or its use in the treatment of microbial infections.  This family includes  two issued
patents in each of  the United States, Europe and Japan, as  well as  issued patents  in 19 other
jurisdictions and 8 pending patent applications in other jurisdictions,  including  one divisional

application in the United States. The standard  term for patents  in this family expires  in 2028. A
patent term adjustment of 303 days has already been obtained in  the United  States  for one
patent.

(cid:127) The third patent family includes patents  and  applications with claims directed to the processes
for the manufacture of lefamulin, crystalline intermediates useful  in the  processes, and the
resulting crystalline salts. This family  includes 11 granted patents and pending patent
applications in Europe and 16 other jurisdictions. The standard term for patents in this  family
expires in 2031.

(cid:127) The fourth patent family includes patents  and  applications with claims directed to processes  for
the synthetic manufacture of crystalline  intermediates  useful  in the manufacture of lefamulin.
This family includes granted patents in Europe and  the United States  and  granted patents in
other jurisdictions and further pending  applications. The standard term for patents in this  family
expires in 2031.

(cid:127) The fifth patent family includes patents  and  applications with claims directed to pharmaceuticals
and treatments for Helicobacter infection, including pleuromutilins, such as lefamulin.  This family
includes issued patents in the United States,  Europe and one other jurisdiction. The standard
term for patents in this family expires  in 2023. A patent term adjustment of  921 days has  already
been obtained for the U.S. patent.

(cid:127) A further patent family is directed  to  pharmaceutical compositions of  lefamulin and  the

PCT-application was recently published.

Our second most advanced product candidate,  BC-7013, is covered specifically in one patent family

with patents granted in the United States,  Europe and  Japan, as well as eight other jurisdictions,  and
pending patent applications in other  jurisdictions.  The  standard term for patents in  this  family expires
in 2027.

The remaining 13 pleuromutilin patent families are directed to either molecules  in the intellectual

property landscape surrounding our product candidates  in development or molecules which can  be
potentially further developed by us but  have  not  yet been pursued.  All patent applications in these
families have been filed at least in the United States and Europe, and most have been filed  in other
countries. The majority of these patent  applications  have already  resulted in granted patents.

Finally, we own one patent family directed to ß-lactamase inhibitor compounds.  Patent applications

in this family have been filed and granted  in  the United  States  and  Europe. The standard  term for
patents in this family expires in 2030.

The term of individual patents depends  upon the legal term  for patents  in the countries in  which
they are obtained. In most countries,  including the  United States, the  patent  term is 20 years from the
filing date of a non-provisional patent  application. In the United States, a patent’s term  may, in certain
cases, be lengthened by patent term adjustment, which  compensates  a patentee for administrative
delays by the U.S. Patent and Trademark  Office,  or the USPTO, in examining and  granting a patent, or
may be shortened if a patent is terminally disclaimed over an  earlier filed patent. The term of  a U.S.
patent that covers  a drug, biological product  or medical  device approved  pursuant to a pre-market
approval, or PMA, may also be eligible  for patent term extension when FDA approval is  granted,
provided that certain statutory and regulatory  requirements  are  met.  The  length of the patent term
extension is related to the length of time  the drug is under regulatory review while  the patent is in
force. The Drug Price Competition and  Patent Term Restoration Act of 1984, or the  Hatch-Waxman
Act, permits a patent term extension of up  to  five  years  beyond  the expiration date set for  the patent.
Patent extension cannot extend the remaining term of a  patent  beyond  a total of 14 years from the
date  of  product approval, only one patent  applicable  to  each regulatory  review period  may be granted
an extension and only those claims reading  on the  approved drug may be extended. Similar  provisions

are available in Europe and certain other foreign jurisdictions to extend the term of a  patent  that
covers an approved drug, provided that statutory and regulatory  requirements are  met. Thus,  in the
future, if and when our product candidates  receive approval  by the FDA  or  foreign regulatory
authorities, we expect to apply for patent  term extensions on issued patents covering those  products,
depending upon the length of the clinical trials for each drug and other factors. The expiration dates  of
our  patents and patent applications referred  to  above are  without  regard to potential patent term
extension or other market exclusivity  that may be available to us.

In addition to patents, we may rely, in some circumstances, on trade secrets  to  protect our
technology and maintain our competitive  position. However, trade  secrets can be difficult to protect.
We  seek to protect our proprietary technology  and  processes, in part, by confidentiality agreements
with our employees, corporate and scientific collaborators, consultants, scientific advisors, contractors
and other third parties. We also seek to preserve the integrity  and confidentiality of our data and trade
secrets by maintaining physical security  of our premises and physical and  electronic security  of  our
information technology systems.

Government Regulation

Government authorities in the United States, at  the federal, state and local level,  and in  other
countries and jurisdictions, including the European Union, extensively regulate, among other  things, the
research, development, testing, manufacture, quality  control, approval, packaging, storage,
recordkeeping, labeling, advertising, promotion,  distribution, marketing, post-approval monitoring and
reporting, and import and export of  pharmaceutical products. The processes for obtaining regulatory
approvals in the United States and in foreign countries and jurisdictions, along with subsequent
compliance with applicable statutes and  regulations  and  other regulatory authorities,  require the
expenditure of substantial time and financial  resources.

Review and Approval of Drugs in the United States

In the United States, the FDA reviews, approves and regulates drugs  under the federal Food,

Drug, and Cosmetic Act, or FDCA, and associated implementing regulations. The 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 and/or sponsor to a variety of administrative or
judicial sanctions,  including refusal by the  FDA to approve pending applications, withdrawal of  an
approval, imposition of a clinical hold,  issuance  of warning  letters and other types of letters,  product
recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines,
refusals of government contracts, restitution,  disgorgement of profits, or  civil  or criminal  investigations
and penalties brought by the FDA and the  U.S. Department of  Justice, or DOJ, or  other  governmental
entities.

An applicant seeking approval to market and distribute a new  drug product  in the United States

must typically undertake the following:

(cid:127) completion of preclinical laboratory tests,  animal studies and formulation studies  in compliance

with the FDA’s good laboratory practice, or  GLP, regulations;

(cid:127) submission to the FDA of an investigational new drug application, or IND, which must take

effect before human clinical trials may begin;

(cid:127) approval by an independent institutional review  board,  or IRB,  representing each clinical  site

before each clinical trial may be initiated;

(cid:127) performance of adequate and well-controlled  human clinical trials in accordance  with good

clinical practices, or GCP, to establish the safety and efficacy  of  the proposed drug  product for
each  indication;

(cid:127) compliance with any post-approval requirements, including the  potential requirement to

implement a Risk Evaluation and Mitigation Strategy, or  REMS, where applicable,  and the
potential to conduct post-approval studies  required by the FDA.

Preclinical Studies

Before an applicant begins testing a compound  with potential therapeutic value  in humans, the

drug candidate enters the preclinical testing stage. Preclinical studies  include laboratory  evaluation of
the purity and stability of the manufactured drug  substance or active pharmaceutical ingredient and the
formulated drug or drug product, as well  as in vitro and animal studies to assess the safety  and activity
of the drug for initial testing in humans and to establish a rationale for therapeutic use. The conduct of
preclinical studies is subject to federal  regulations and requirements, including GLP regulations. The
results of the preclinical tests, together  with manufacturing information, analytical data, any available
clinical data or literature and plans for clinical studies, among other things, are  submitted to the FDA
as part of an IND. Additional long-term preclinical testing, such as animal tests  of reproductive adverse
events and carcinogenicity, may continue after the  IND is submitted.

Companies usually must complete some long-term preclinical testing, such as animal tests of long

term exposure and reproductive adverse  events, and must  also develop  additional information about  the
chemistry and physical characteristics of  the investigational product  and finalize a process for
manufacturing the  product in commercial  quantities  in  accordance with cGMP requirements. The
manufacturing process must be capable  of consistently producing quality batches of the candidate
product  and, among other things, the manufacturer must develop methods for  testing the  identity,
strength, quality and purity of the final product. Additionally, appropriate packaging must be selected
and tested and stability studies must be conducted  to  demonstrate that the candidate product does not
undergo unacceptable deterioration over its shelf life.

The IND and IRB Processes

An IND is an exemption from the FDCA that allows an unapproved drug to be shipped in
interstate commerce for use in an investigational clinical  trial and a request  for FDA authorization to
administer an investigational drug to  humans. Such authorization must be secured prior to interstate
shipment and administration of any new drug that is  not  the subject  of  an approved NDA. In support
of a request for an IND, applicants must submit a protocol for each clinical trial and any subsequent
protocol amendments must be submitted to the FDA as part of the IND. In addition, the results of the
preclinical tests, together with manufacturing information, analytical data, any available clinical data or
literature and plans for clinical trials, among other things,  are submitted  to  the FDA as part of an IND.
The FDA requires a 30-day waiting period after the filing of each IND  before  clinical trials  may begin.

This waiting period is designed to allow the FDA to review the IND to determine whether  human
research subjects will be exposed to unreasonable  health risks. At  any time during this 30-day period,
the FDA may raise concerns or questions  about  the conduct of the trials as outlined in the IND and
impose a clinical hold. In this case, the  IND  sponsor  and  the FDA must resolve any  outstanding
concerns before clinical trials can begin.

Following commencement of a clinical trial under  an IND,  the  FDA  may also place a clinical hold

or partial clinical hold on that trial. A  clinical  hold  is an order issued by the  FDA to the sponsor  to
delay a proposed clinical investigation or to suspend an ongoing investigation.  A partial  clinical hold is
a delay or suspension of only part of  the clinical work requested under the IND.  For example, a
specific  protocol or part of a protocol is  not allowed to proceed, while  other  protocols  may do so. No
more than 30 days after imposition of a clinical  hold  or partial clinical hold, the  FDA  will  provide the
sponsor  a written explanation of the basis  for the hold. Following  issuance  of a clinical hold or partial
clinical hold, an investigation may only  resume  after the FDA has notified  the sponsor that the
investigation may proceed. The FDA will  base that determination on  information  provided by the
sponsor  correcting the deficiencies previously cited or  otherwise  satisfying the FDA  that  the
investigation can proceed.

A sponsor may choose, but is not required, to conduct a foreign clinical study under  an IND.

When a foreign clinical study is conducted under  an IND, all FDA IND requirements must be met
unless waived. When the foreign clinical study  is not conducted under  an IND, the sponsor  must  ensure
that the study complies with FDA certain  regulatory requirements in order to use the  study as  support
for an IND or application for marketing approval. Specifically, on  April 28,  2008, the FDA amended  its
regulations governing the acceptance of foreign  clinical  studies not conducted  under an  investigational
new drug application as support for an IND or a new drug application. The final rule provides that
such studies must be conducted in accordance with  good clinical  practice, or GCP, including review and
approval by an independent ethics committee, or  IEC, and  informed consent from subjects. The GCP
requirements in the final rule encompass both ethical and data  integrity standards for  clinical studies.
The FDA’s regulations are intended to  help  ensure  the protection of human subjects  enrolled in
non-IND foreign clinical studies, as well as  the quality and  integrity of  the  resulting data. They further
help ensure that non-IND foreign studies are conducted in a manner comparable  to  that  required for
IND studies.

In addition to the foregoing IND requirements,  an IRB  representing each institution  participating
in the clinical trial must review and approve  the plan for any clinical trial before it commences at that
institution, and the IRB must conduct continuing review and reapprove the study at least annually. The
IRB must review and approve, among  other things, the study protocol  and informed consent
information to be provided to study subjects. An IRB  must  operate in compliance  with FDA
regulations. An IRB can suspend or  terminate  approval of a clinical  trial  at its institution,  or an
institution it represents, if the clinical trial  is not being conducted in accordance with the IRB’s
requirements or if the product candidate has been  associated with  unexpected serious harm to patients.

Additionally, some trials are overseen by an independent group of qualified experts organized  by

the trial sponsor, known as a data safety  monitoring board or committee.  This group provides
recommendations on whether or not  a  trial should move forward at designated check points based on
unblinded safety data from the study  that only the  group has access to.. Suspension or termination of
development during any phase of clinical  trials  may  occur if  it is  determined that the participants or
patients are being exposed to an unacceptable  health risk.  Other reasons  for suspension or termination
may be made by us based on evolving business  objectives  and/or competitive climate.

Information about certain clinical trials must be submitted within specific  timeframes to the
National Institutes of Health, or NIH,  for public  dissemination on its ClinicalTrials.gov website.

Human Clinical Studies in Support of an  NDA

Clinical trials involve the administration of the  investigational product  to  human subjects under the

supervision of qualified investigators in accordance  with GCP  requirements,  which include, among
other things, the requirement that all research subjects provide their informed consent in writing  before
their participation in any clinical trial.  Clinical trials are conducted  under written study  protocols
detailing, among other things, the inclusion and exclusion criteria, the  objectives  of  the study, the
parameters to be used in monitoring  safety  and  the effectiveness criteria to be evaluated.

Human clinical trials are typically conducted  in the following sequential phases, which may  overlap

or be combined:

(cid:127) Phase 1: The drug is initially introduced into healthy  human subjects  or,  in certain indications

such as cancer, patients with the target disease  or condition and tested for safety,  dosage
tolerance, absorption, metabolism, distribution, excretion and,  if possible, to  gain an early
indication of its effectiveness and to determine optimal dosage.

(cid:127) Phase 2: The drug is administered to 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 and optimal dosage.

(cid:127) Phase 3: The drug is administered to an expanded  patient  population, generally at geographically

dispersed clinical trial sites, in well-controlled  clinical  trials to generate  enough data to
statistically evaluate the efficacy and safety  of the product  for approval, to establish  the overall
risk-benefit profile of the product, and  to  provide adequate information  for the  labeling of the
product.

(cid:127) Phase 4: Post-approval studies, which  are conducted following initial  approval, are typically

conducted to gain additional experience and data from  treatment of patients in  the intended
therapeutic indication.

Progress reports detailing the results  of the  clinical trials  must  be  submitted at  least  annually  to  the

FDA and more frequently if serious adverse  events occur. In  addition,  IND safety reports must be
submitted to the FDA for any of the  following:  serious and unexpected suspected adverse reactions;
findings from other studies or animal or in vitro testing that suggest a significant risk in  humans
exposed  to the drug; and any clinically important increase in  the case of  a  serious suspected adverse
reaction over that listed in the protocol or investigator brochure. Phase  1, Phase  2 and Phase 3 clinical
trials may not be completed successfully within any specified period, or at all. Furthermore, the FDA or
the sponsor may suspend or terminate  a clinical trial at  any  time on  various grounds, including  a
finding that the research subjects are being exposed to an unacceptable  health risk.  Similarly, an IRB
can suspend or terminate approval of  a clinical trial  at its institution,  or  an institution  it represents,  if
the clinical trial is not being conducted  in  accordance with  the IRB’s requirements or  if  the drug has
been associated with unexpected serious harm to patients. The  FDA  will typically inspect one or more
clinical sites to assure compliance with GCP and  the integrity of the clinical data submitted.

Concurrent with clinical trials, companies often complete additional animal  studies and must also
develop additional information about the  chemistry and physical characteristics of the drug as  well as
finalize a process for manufacturing the  product in  commercial quantities in  accordance  with cGMP
requirements. The manufacturing process must be capable  of consistently  producing quality batches of
the drug candidate and, among other things, must develop methods  for testing the identity, strength,
quality, purity, and potency of the final  drug. Additionally,  appropriate packaging must be selected and
tested and stability studies must be conducted to demonstrate  that the drug candidate does  not  undergo
unacceptable deterioration over its shelf life.

Special  Protocol Assessment Agreements

A Special Protocol Assessment, or SPA, agreement is an agreement between a  drug manufacturer

and the FDA on the design and size  of  studies  and  clinical  trials  that can be used  for approval  of a
drug or biological  product. The FDA’s  guidance on such agreements  states that an agreement  may not
be changed by the manufacturer or the agency unless  through a written agreement  of the two entities
or if FDA determines a substantial scientific issue essential to determining the  safety or effectiveness of
the drug. The protocols that are eligible for SPA agreements are:  animal carcinogenicity protocols, final
product  stability protocols and clinical protocols for Phase 3 trials whose data  will form  the primary
basis for an efficacy claim.

Specifically, under the FDCA, the FDA may meet with sponsors, provided  certain conditions are
met, for the purpose of reaching a SPA agreement on  the design and size  of  clinical trials  intended to
form the primary basis of an efficacy  claim  in a marketing application. If a sponsor makes a  reasonable
written request to meet with the FDA for  the purpose of reaching  agreement on  the design and size  of
a clinical trial, then the FDA will meet with the sponsor. If  an agreement  is reached, the FDA will
reduce the agreement to writing and  make it part of the  administrative record.  An agreement may  not
be changed by the sponsor or FDA after  the trial  begins, except with the written agreement of  the
sponsor  and FDA, or if the director  of  the  FDA reviewing division  determines  that  ‘‘a substantial
scientific issue essential to determining  the safety  or effectiveness of the drug’’  was  identified after the
testing began. If a sponsor and the FDA meet  regarding the design and size of a  clinical trial and the
parties cannot agree that the trial design  is adequate to meet the  goals of the  sponsor, the FDA will
clearly  state the reasons for the disagreement  in a letter to the sponsor. We reached agreement with
the FDA in September 2015 on a SPA  regarding the study design of our first Phase  3 clinical trial of
lefamulin for the treatment of CABP.

Submission of an NDA to the FDA

Assuming successful completion of required  clinical testing and other  requirements, the results of

the preclinical and clinical studies, together with detailed information relating to the product’s
chemistry, manufacture, controls and proposed labeling,  among  other things,  are submitted  to  the FDA
as part of an NDA requesting approval  to  market the drug product for  one or more  indications. Under
federal law, the submission of most NDAs is  additionally  subject to an application user  fee,  which for
federal fiscal year 2017 is $2,038,100,  and  the sponsor of an approved NDA is  also subject to annual
product  and establishment user fees,  which  for fiscal year  2017 are $97,750 per product and $512,000
per  establishment Exceptions or waivers for user fees exist  for  a  small company (fewer  than 500
employees, including employees and  affiliates) satisfying  certain requirements  and products with  orphan
drug designation for a particular indication are not subject to an application user fee provided there
are no other intended uses in the NDA. We believe  that we will not be subject  to  an application user
fee.

Following submission of an NDA, the FDA  conducts  a preliminary  review of an NDA  generally
within 60 calendar days of its receipt and strives  to  inform the sponsor  by  the 74th  day after the FDA’s
receipt of the submission whether the  application is  sufficiently complete  to permit substantive review.
The FDA may request additional information  rather than accept an NDA  for filing. In this event, the
application must be resubmitted with  the additional information.  The  resubmitted application is also
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. The FDA  has agreed to certain performance goals in the
review process of NDAs. Standard review, representing  most such  applications  are meant  to  be
reviewed within ten months from the  date of filing. Priority  review applications are meant to be
reviewed within six months of filing. The  review  process may be extended  by  the FDA for three
additional months to consider new information or clarification provided by the applicant to address  an
outstanding deficiency identified by the FDA following the  original  submission.

Before approving an NDA, the FDA typically will inspect the  facility or facilities where  the product

is or will be manufactured. These pre-approval  inspections may cover all facilities associated  with an
NDA  submission, including drug component manufacturing (such as  active pharmaceutical  ingredients),
finished drug product manufacturing,  and  control testing laboratories. The FDA will not approve an
application unless it determines that  the  manufacturing processes and facilities are in compliance with
cGMP requirements and adequate to  assure consistent production  of  the product within required
specifications. Additionally, before approving an  NDA,  the FDA  will typically inspect one or more
clinical sites to assure compliance with GCP.

In addition, as a condition of approval, the FDA may  require an applicant to develop a REMS.

REMS use risk minimization strategies  beyond  the professional labeling to ensure  that  the benefits of
the product outweigh the potential risks.  To  determine whether a REMS  is  needed, the  FDA will
consider the size of the population likely to use  the product, seriousness  of the disease, expected
benefit of the product, expected duration of treatment, seriousness of known  or potential adverse
events, and whether the product is a new molecular entity.  REMS can include medication guides,
physician  communication plans for healthcare professionals, and elements  to  assure safe use, or
ETASU. ETASU may include, but are  not limited to, special  training or certification for prescribing or
dispensing, dispensing only under certain  circumstances,  special monitoring, and  the use of  patient
registries. The FDA may require a REMS before approval or post-approval  if  it becomes aware of a
serious risk associated with use of the  product.  The requirement  for a REMS can materially affect the
potential market and profitability of a  product.

The FDA may refer an application for  a novel drug  to  an advisory  committee or explain  why such

referral was not made. Typically, an advisory committee is a  panel  of  independent  experts,  including
clinicians and other scientific experts, that  reviews, evaluates and provides 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 relating to approval of a new drug  product.

Fast Track, Breakthrough Therapy, Priority  Review and Regenerative Advanced  Therapy Designations

The FDA is authorized to designate certain  products for expedited  review if they are intended to
address an unmet medical need in the treatment of a serious or life-threatening disease or condition.
These programs are referred to as fast track designation, breakthrough therapy designation, priority
review designation and regenerative advanced therapy designation.

Specifically, the FDA may designate  a  product for Fast  Track  review if it is intended, whether

alone or in combination with one or  more other products,  for the treatment of  a serious or
life-threatening disease or condition,  and  it demonstrates the potential to  address unmet  medical  needs
for such a disease or condition. For Fast Track products, sponsors may have  greater interactions with
the FDA and the FDA may initiate review of sections of a Fast Track product’s application before  the
application is complete. This rolling review may be available if  the FDA determines,  after preliminary
evaluation of clinical data submitted by  the  sponsor,  that  a Fast Track product may  be  effective. The
sponsor  must also provide, and the FDA  must approve, a  schedule  for the  submission of the remaining
information and the sponsor must pay  applicable user fees. However, the FDA’s time  period goal for
reviewing a Fast Track application does  not  begin  until the last  section  of the application is  submitted.
In addition, the Fast Track designation may be withdrawn by  the  FDA if the FDA  believes that the
designation is no longer supported by data  emerging in  the clinical trial  process.

Second, a product may be designated as a  Breakthrough  Therapy if it  is intended, either alone or

in combination with one or more other  products, to treat a serious or life-threatening disease or
condition and preliminary clinical evidence indicates that the  product may demonstrate substantial
improvement over existing therapies on  one or more clinically  significant endpoints, such as substantial

treatment effects observed early in clinical development. The  FDA may take certain  actions with
respect to Breakthrough Therapies, including  holding  meetings  with the  sponsor throughout the
development process; providing timely advice to the product sponsor regarding development and
approval; involving more senior staff in  the review process;  assigning a  cross-disciplinary project lead
for the review team; and taking other steps to design the clinical  trials in  an efficient manner.

Third, the FDA may designate a product for priority review  if it  is a product  that  treats a serious

condition and, if approved, would provide  a significant improvement in safety or effectiveness. The
FDA determines, on a case- by-case  basis,  whether the  proposed product  represents a significant
improvement when compared with other  available therapies. Significant improvement may be illustrated
by evidence of increased effectiveness in the  treatment of a  condition, elimination  or substantial
reduction of a treatment-limiting product reaction, documented enhancement of  patient  compliance
that may lead to improvement in serious  outcomes, and  evidence of safety  and effectiveness in  a new
subpopulation. A priority designation  is  intended to direct  overall attention and  resources  to  the
evaluation of such applications, and to shorten the FDA’s goal for taking action on a marketing
application from ten months to six months.

Fast Track, Breakthrough Therapy and Priority  Review Designations

Accelerated Approval Pathway

The FDA may grant accelerated approval to a drug for a serious or life-threatening condition  that

provides meaningful therapeutic advantage  to  patients over existing treatments based  upon a
determination that the drug has an effect  on  a surrogate  endpoint that is reasonably  likely to predict
clinical benefit. The FDA may also grant accelerated approval for  such a drug  when the  product has an
effect on an intermediate clinical endpoint that can be measured earlier than  an effect on  irreversible
morbidity or mortality, or IMM, and  that is  reasonably likely  to  predict an effect on irreversible
morbidity or mortality or other clinical benefit,  taking into account  the severity, rarity,  or prevalence of
the condition and the availability or lack  of alternative treatments. Drugs granted accelerated approval
must meet the same statutory standards  for safety and effectiveness as those granted traditional
approval.

For the purposes of accelerated approval, a surrogate  endpoint is a marker, such  as a laboratory

measurement, radiographic image, physical sign, or  other measure that is  thought  to  predict clinical
benefit, but is not itself a measure of  clinical benefit. Surrogate endpoints can often be measured  more
easily or more rapidly than clinical endpoints.  An intermediate clinical endpoint  is a measurement of a
therapeutic effect that is considered reasonably  likely to predict the clinical  benefit of a drug, such as
an effect on IMM. The FDA has limited  experience with accelerated approvals based on intermediate
clinical endpoints, but has indicated that  such endpoints generally may support accelerated approval
where  the therapeutic effect measured  by  the endpoint is  not itself  a  clinical  benefit and basis for
traditional approval, if there is a basis for  concluding that the therapeutic effect is  reasonably likely  to
predict the ultimate clinical benefit of  a drug.

The accelerated approval pathway is  most often used in  settings in which  the course  of a disease is

long and an extended period of time is  required to measure the  intended clinical benefit of  a drug,
even if the effect on the surrogate or intermediate clinical endpoint occurs rapidly. Thus,  accelerated
approval has been used extensively in the  development and approval of drugs for treatment of a  variety
of cancers in which the goal of therapy is generally  to  improve survival or  decrease morbidity and the
duration of the typical disease course requires lengthy and sometimes large trials  to  demonstrate  a
clinical or survival benefit. The accelerated approval pathway is usually  contingent on a sponsor’s
agreement to conduct, in a diligent manner, additional  post-approval confirmatory studies to verify and
describe the drug’s clinical benefit. As a  result,  a drug candidate approved on this basis is subject to
rigorous post-marketing compliance requirements,  including  the completion  of Phase 4 or post-approval

clinical trials to confirm the effect on the  clinical endpoint. Failure to conduct required post-approval
studies,  or confirm a clinical benefit  during post-marketing studies, would  allow  the FDA  to  withdraw
the drug from the market on an expedited basis. All promotional materials for drug candidates
approved under accelerated regulations  are  subject to prior  review by the FDA.

Limited Population Antibacterial Drug Pathway

With passage of the CURES Act, Congress  authorized  FDA to approve an antibacterial or

antifungal drug, alone or in combination with one or more other  drugs, as a  ‘‘limited population drug.’’
To qualify for this approval pathway,  the drug  must be intended to treat a  serious or life-threatening
infection in a limited population of patients with unmet  needs; the standards for  approval of drugs and
biologics under the FDCA and PHSA must  be  satisfied;  and FDA must receive a  written  request from
the sponsor to approve the drug as a  limited  population drug pursuant to this provision. The FDA’s
determination of safety and effectiveness for  such a  product must reflect the benefit-risk profile  of  such
drug in the intended limited population,  taking into account the  severity, rarity,  or prevalence of  the
infection the drug is intended to treat  and  the availability  or lack of alternative treatment  in such  a
limited population.

Any drug or biologic approved under  this pathway  must be labeled with the statement ‘‘Limited

Population’’ in a prominent manner  and  adjacent  to  the proprietary name of the drug  or biological
product.  The  prescribing information must  also state that  the drug is indicated for use  in a limited and
specific  population of patients and copies  of all promotional materials relating to the drug must be
submitted to FDA at least 30 days prior  to dissemination  of the materials. If  FDA subsequently
approves the drug for a broader indication, the  agency may remove any post-marketing conditions,
including requirements with respect to  labeling  and  review of promotional materials applicable to the
product.  Nothing in this pathway to approval  of  a limited population  drug prevents sponsors  of such
products from seeking designation or  approval  under other provisions of the  FDCA, such  as
accelerated approval.

The FDA’s Decision on an NDA

On the basis of the FDA’s evaluation of the NDA and accompanying information, including the

results of the inspection of the manufacturing  facilities,  the FDA  may  issue an approval letter or  a
complete response letter. An approval letter authorizes commercial  marketing  of the product  with
specific  prescribing information for specific indications. A complete response  letter generally outlines
the deficiencies in the submission and  may require  additional,  sometimes  substantial, testing or
information in order for the FDA to reconsider  the application. If and when  those deficiencies have
been addressed to the FDA’s satisfaction in a resubmission of the NDA, the FDA will  issue an  approval
letter. The FDA has committed to reviewing such  resubmissions in two or  six months depending  on the
type of information included. Even with  submission  of this  additional  information, the  FDA ultimately
may decide that the application does  not  satisfy the  regulatory criteria  for approval.

If the FDA approves a product, it may limit the approved indications  for use for the product,
require that contraindications, warnings  or precautions  be included in  the product labeling, require that
post-approval studies, including Phase  4 clinical trials, be conducted to further  assess the drug’s safety
after approval, require testing and surveillance  programs  to  monitor the product after
commercialization, or impose other conditions, including distribution restrictions or other risk
management mechanisms, including REMS, which can  materially affect  the potential market and
profitability of the product. The FDA may  prevent or limit further marketing of a product based  on the
results of post-market studies or surveillance  programs. After approval,  many types of changes  to  the
approved product, such as adding new indications,  manufacturing  changes and  additional labeling
claims, are subject to further testing  requirements  and  FDA review  and approval.

Post-Approval Regulation

Drugs manufactured or distributed pursuant to FDA approvals  are subject  to  pervasive and

continuing regulation by the FDA, including, among other things,  requirements  relating to
recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and
reporting of adverse experiences with the  product. After approval, most changes  to  the approved
product,  such as adding new indications or other labeling claims, are subject to prior FDA review and
approval. There also are continuing, annual user fee  requirements for any marketed products  and the
establishments at which such products are manufactured, as  well as  new application fees for
supplemental applications with or without clinical data.

In addition, drug manufacturers and other entities involved in the manufacture  and distribution  of
approved drugs are required to register their  establishments with the FDA and state  agencies, and are
subject to periodic unannounced inspections by the FDA and these state  agencies for  compliance with
cGMP requirements. Changes to the  manufacturing  process are strictly  regulated  and often require
prior FDA approval before being implemented. FDA regulations  also  require  investigation and
correction of any deviations from cGMP and impose reporting and documentation requirements upon
the sponsor and any third-party manufacturers that  the sponsor may decide to use. Accordingly,
manufacturers must continue to expend  time, money  and effort  in the area  of  production  and quality
control to maintain cGMP compliance.

Once an approval is granted, the FDA may withdraw the  approval if compliance  with regulatory

requirements and standards is not maintained or if problems occur after the  product reaches  the
market. Later discovery of previously  unknown problems  with a product, including adverse events of
unanticipated severity or frequency, or  with manufacturing processes, or failure to comply with
regulatory requirements, may result in  revisions  to  the approved  labeling to add  new safety  information;
imposition of post-market studies or clinical  trials to assess new  safety risks; or  imposition of
distribution or other restrictions under  a REMS program. Other potential consequences include, among
other things:

(cid:127) restrictions on the marketing or manufacturing of the product,  suspension of the  approval, or

complete withdrawal of the product from the  market  or product recalls;

(cid:127) fines, warning letters or holds on post-approval clinical trials;

(cid:127) refusal of the FDA to approve pending NDAs or  supplements to approved NDAs, or  suspension

or revocation of product license approvals;

(cid:127) product seizure or detention, or refusal  to  permit  the import  or  export of  products;  or

(cid:127) injunctions or the imposition of civil or  criminal penalties.

The FDA strictly regulates marketing, labeling, advertising and promotion of products  that  are
placed on the market. Drugs may be  promoted only for the  approved indications and in accordance
with the provisions of the approved label. The FDA and  other agencies actively enforce the  laws  and
regulations prohibiting the promotion of off-label uses,  and a company that is  found to have improperly
promoted off-label uses may be subject to significant liability.

In addition, the distribution of prescription  pharmaceutical products is  subject to the Prescription

Drug Marketing Act, or PDMA, and  its implementing regulations, as  well as the Drug Supply Chain
Security  Act, or DSCA, which regulate  the distribution and tracing of prescription drugs and
prescription drug samples at the federal  level, and set minimum  standards for the regulation  of  drug
distributors by the states. The PDMA, its  implementing regulations  and state laws limit the  distribution
of prescription pharmaceutical product samples and the DSCA imposes requirements to ensure
accountability in distribution and to identify and remove counterfeit and other illegitimate products
from the market.

Section 505(b)(2) NDAs

NDAs for most new drug products are based on  two  full clinical studies which  must  contain
substantial evidence of the safety and  efficacy of  the proposed new product.  These applications are
submitted under Section 505(b)(1) of the  FDCA. The FDA is,  however, authorized to approve an
alternative type of NDA under Section 505(b)(2)  of  the FDCA. This type of application allows the
applicant to rely, in part, on the FDA’s  previous  findings of safety  and efficacy  for a  similar product,  or
published literature. Specifically, Section 505(b)(2)  applies to NDAs for a drug  for which the
investigations made to show whether or not the drug  is safe for use  and effective  in use  and relied
upon by the applicant for approval of the  application ‘‘were not conducted by or for the applicant and
for which the applicant has not obtained a right of reference or use from  the person by or for whom
the investigations were conducted.’’

Thus, Section 505(b)(2) authorizes the FDA to approve an NDA based on safety and effectiveness

data that were not developed by the  applicant. NDAs filed under  Section 505(b)(2) may provide  an
alternate and potentially more expeditious pathway to FDA  approval  for new or  improved formulations
or new uses of previously approved products. If the Section  505(b)(2) applicant  can establish  that
reliance on the FDA’s previous approval is  scientifically  appropriate,  the applicant  may eliminate the
need to conduct certain preclinical or clinical studies  of the new  product. The  FDA  may also require
companies to perform additional studies or measurements to support the  change  from the approved
product.  The  FDA may then approve  the  new  drug candidate for all or some of the  label indications
for which the referenced product has been approved,  as well  as for any  new indication sought  by  the
Section 505(b)(2) applicant.

Abbreviated New Drug Applications for Generic Drugs

In 1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress authorized  the
FDA to approve generic drugs that are  the same as  drugs  previously approved by the FDA under the
NDA  provisions of the statute. To obtain approval of  a generic drug,  an  applicant must submit  an
abbreviated new drug application, or  ANDA,  to  the agency. In support  of such applications, a  generic
manufacturer may rely on the preclinical and clinical  testing previously conducted for a drug product
previously approved under an NDA, known as  the reference  listed drug, or  RLD.

Specifically, in order for an ANDA to be approved,  the FDA must find  that the  generic version is

identical to the RLD with respect to the active ingredients,  the route of administration, the dosage
form, and the strength of the drug. At the same time, the FDA must also determine that the generic
drug is ‘‘bioequivalent’’ to the innovator  drug. Under the statute, a generic  drug is bioequivalent to a
RLD if ‘‘the rate and extent of absorption of the  drug do not show a significant difference from the
rate and extent of absorption of the  listed drug.’’

Upon approval of an ANDA, the FDA indicates  whether  the generic product is  ‘‘therapeutically

equivalent’’ to the RLD in its publication ‘‘Approved Drug Products  with Therapeutic Equivalence
Evaluations,’’ also referred to as the ‘‘Orange Book.’’ Physicians and pharmacists  consider a  therapeutic
equivalent generic drug to be fully substitutable for the RLD. In addition,  by  operation of  certain  state
laws and numerous health insurance  programs,  the FDA’s designation of therapeutic equivalence often
results in  substitution of the generic drug  without the knowledge  or consent of either the  prescribing
physician  or patient.

Under the Hatch-Waxman Amendments,  the FDA  may  not  approve  an ANDA until any applicable
period of non-patent exclusivity for the  RLD has expired. The  FDCA provides a  period of five years of
non-patent data exclusivity for a new drug  containing a  new chemical entity.  For  the purposes  of  this
provision, a new chemical entity, or NCE,  is a drug  that contains no active moiety that has previously
been approved by  the FDA in any other NDA. An  active moiety is the molecule or ion  responsible  for
the physiological or pharmacological action of the  drug substance. In cases  where such exclusivity has

been granted, an ANDA may not be filed with  the FDA until  the expiration  of five  years  unless the
submission is accompanied by a Paragraph IV  certification,  in which  case the applicant may submit its
application four years following the original product approval.  The FDCA also  provides for a period of
three years of exclusivity if the NDA includes reports of one or more  new clinical investigations, other
than bioavailability or bioequivalence studies, that were conducted by or for the applicant and are
essential to the approval of the application.  This three-year exclusivity  period often protects  changes to
a previously approved drug product, such  as a new dosage  form,  route  of administration,  combination
or indication.

Hatch-Waxman Patent Certification and  the  30-Month Stay

Upon approval of an NDA or a supplement thereto, NDA sponsors are required to list with  the
FDA each patent with claims that cover the applicant’s product or an approved  method of using the
product.  Each of the patents listed by the NDA sponsor is published in the Orange Book. When an
ANDA applicant files its application  with the  FDA,  the applicant  is required to certify to the FDA
concerning any patents listed for the  reference  product in  the Orange  Book, except  for patents  covering
methods of use for which the ANDA applicant  is not seeking approval.  To the  extent that the
Section 505(b)(2) applicant is relying  on studies conducted for an already  approved product, the
applicant is required to certify to the  FDA  concerning any patents  listed for the approved  product in
the Orange Book to the same extent that  an ANDA applicant would.

Specifically, the applicant must certify with  respect to each patent that:

(cid:127) the required patent information has not been  filed;

(cid:127) the listed patent has expired;

(cid:127) the listed patent has not expired, but will  expire on a particular date and approval is sought  after

patent expiration; or

(cid:127) the listed patent is invalid, unenforceable or will not be infringed by the  new product.

A certification that the new product  will  not  infringe  the already approved product’s  listed patents
or that such patents are invalid or unenforceable is called a Paragraph IV  certification. If  the applicant
does not challenge the listed patents or indicates that it is  not  seeking  approval of a patented method
of use, the ANDA application will not be approved until  all the listed  patents claiming the referenced
product  have expired (other than method  of use  patents involving indications for which the  ANDA
applicant is not seeking approval).

If the ANDA applicant has provided a Paragraph IV certification to the FDA, the  applicant must
also send notice of the Paragraph IV certification to the NDA and patent holders  once the ANDA has
been accepted for filing by the FDA. The NDA and patent holders may then initiate  a patent
infringement lawsuit in response to the notice of the Paragraph IV  certification. The  filing of a  patent
infringement lawsuit within 45 days after the receipt of a Paragraph  IV certification automatically
prevents the FDA from approving the ANDA until the  earlier of 30  months after  the receipt of the
Paragraph IV notice, expiration of the patent, or  a decision in the  infringement case that is favorable to
the ANDA applicant.

To the extent that the Section 505(b)(2) applicant is relying  on studies conducted  for an  already
approved product, the applicant is required to certify to the  FDA concerning  any patents  listed for the
approved product in the Orange Book  to  the same extent that an ANDA applicant would.  As a result,
approval of a Section 505(b)(2) NDA  can be stalled until  all the listed  patents  claiming  the referenced
product  have expired, until any non-patent exclusivity, such  as exclusivity for obtaining approval of  a
new chemical entity, listed in the Orange  Book for  the referenced product  has expired, and, in the case
of a Paragraph IV certification and subsequent patent infringement  suit, until the earlier of 30 months,
settlement of the lawsuit or a decision in  the infringement case  that is favorable to the
Section 505(b)(2) applicant.

Pediatric Studies and Exclusivity

Under the Pediatric Research Equity Act of 2003, an NDA  or  supplement  thereto  must  contain

data that are adequate to assess the  safety  and effectiveness of  the  drug 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. With enactment of the FDASIA in
2012, sponsors must also submit pediatric study plans prior to the  assessment data. Those  plans must
contain an outline of the proposed pediatric  study or studies  the applicant  plans to conduct, including
study objectives and design, any deferral or waiver requests, and other information required  by
regulation. The applicant, the FDA, and the FDA’s internal review  committee must then  review the
information submitted, consult with each  other, and agree upon a final  plan. The FDA  or the applicant
may request an amendment to the plan at any  time.

The FDA may, on its own initiative or at the  request of the applicant, grant deferrals  for

submission of some or all pediatric data  until after approval  of  the product for use  in adults, or full or
partial waivers from the pediatric data  requirements.  Additional  requirements  and procedures relating
to deferral requests and requests for  extension of  deferrals are contained in the  FDASIA. Unless
otherwise required by regulation, the  pediatric data requirements do  not  apply to products with  orphan
designation.

Pediatric exclusivity is another type of non-patent marketing exclusivity  in the United  States and, if
granted, provides for the attachment of an  additional six months of  marketing  protection to the  term of
any existing regulatory exclusivity, including  the non-patent and orphan  exclusivity. This  six-month
exclusivity may be granted if an NDA  sponsor submits pediatric data that fairly respond to a written
request from the FDA for such data. The  data do  not  need to show the product to be effective in the
pediatric population studied; rather, if  the clinical trial is deemed to fairly respond to the FDA’s
request, the additional protection is granted. If  reports of requested pediatric studies are submitted  to
and accepted by the FDA within the statutory  time limits, whatever statutory or regulatory  periods  of
exclusivity or patent protection cover the  product are extended by  six months.  This is not a patent term
extension, but it effectively extends the  regulatory period during which the FDA  cannot approve
another application.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, the FDA may designate  a drug product as an ‘‘orphan drug’’ if it  is

intended to treat a rare disease or condition (generally meaning  that it affects fewer than 200,000
individuals in the United States, or more  in cases  in which there is  no reasonable  expectation that the
cost of developing and making a drug product  available in the United  States for  treatment of the
disease or condition will be recovered  from sales of the product).  A company must request orphan
product  designation before submitting  an NDA.  If the request is granted, the  FDA  will disclose  the
identity of the therapeutic agent and its potential  use. Orphan product designation does not convey  any
advantage in or shorten the duration  of the regulatory review  and approval  process.

If a  product with orphan status receives the first FDA approval  for  the disease or condition for

which  it has such designation or for a  select  indication or use within the rare disease or condition for
which  it was designated, the product generally will receive orphan product  exclusivity. Orphan product
exclusivity means that the FDA may not approve  any other applications for the  same product  for the
same indication for seven years, except in certain limited circumstances. Competitors  may receive
approval of different products for the indication for which the  orphan product has exclusivity and  may
obtain approval for the same product  but  for  a different indication.  If a drug  or drug product
designated as an orphan product ultimately receives  marketing  approval for an indication broader than
what was designated in its orphan product  application,  it may not  be  entitled to exclusivity.

GAIN Exclusivity for Antibiotics

In 2012, Congress passed legislation  known  as the Generating Antibiotic Incentives Now  Act, or
GAIN Act. This legislation is designed  to  encourage the  development of antibacterial and antifungal
drug products that treat pathogens that  cause serious and life-threatening infections. To that end, the
law grants an additional five years of  exclusivity  upon the approval of an NDA for a drug  product
designated by FDA as a QIDP. Thus, for  a QIDP, the periods of five-year new chemical entity
exclusivity, three-year new clinical investigation  exclusivity, and seven-year orphan  drug exclusivity,
would become ten years, eight years,  and  twelve years, respectively.

A QIDP is defined in the GAIN Act to mean ‘‘an  antibacterial or antifungal drug for human use

intended to treat serious or life-threatening infections, including those caused by (1) an antibacterial or
antifungal resistant pathogen, including novel or emerging  infectious pathogens’’ or (2)  certain
‘‘qualifying pathogens.’’ A ‘‘qualifying pathogen’’  is a pathogen that has  the potential to pose a serious
threat to public health (such as resistant Gram-positive pathogens, multi-drug resistant Gram-negative
bacteria, multi-drug resistant tuberculosis,  and C. difficile) and that is included in a list established and
maintained by FDA. A drug sponsor  may request the  FDA  to  designate  its product as a QIDP any
time before the submission of an NDA. The FDA must make  a QIDP determination within 60 days of
the designation request. A product designated  as a QIDP will be granted  priority review by the FDA
and can qualify for ‘‘fast track’’ status.

The additional five years of exclusivity under  the GAIN Act for drug products designated  by  the
FDA as QIDPs applies only to a drug  that is  first approved on or after  July 9, 2012. Additionally, the
five year exclusivity extension does not apply to: a supplement to an application under  FDCA
Section 505(b) for any QIDP for which an extension  is in effect  or has expired; a subsequent
application filed with respect to a product approved by  the FDA  for a  change  that  results in  a new
indication, route of administration, dosing  schedule,  dosage form,  delivery system, delivery  device or
strength; or a product that does not meet  the definition  of a QIDP under  Section 505(g)  based upon its
approved uses. The FDA has designated each  of the IV and oral  formulations of lefamulin as a  QIDP
and also granted fast track designations  to each of these formulations of lefamulin.

Patent Term Restoration and Extension

A patent claiming a new drug product may be eligible for a limited patent term extension under
the Hatch-Waxman Amendments, which permits a patent  restoration of  up to five  years  for patent term
lost during product development and the  FDA regulatory  review. The restoration  period granted  is
typically one-half the time between the effective  date of  an IND and the submission  date of an  NDA,
plus the time between the submission date of an NDA and  the ultimate  approval date.  Patent term
restoration cannot  be used to extend the  remaining term  of a patent past a  total  of 14 years from the
product’s approval date. Only one patent applicable to an  approved drug product is eligible  for the
extension, and the application for the  extension must be submitted prior to the expiration of the patent
in question. A patent that covers multiple  drugs for which approval is sought can only be extended in
connection with one of the approvals.  The USPTO reviews and approves the application for  any patent
term extension or restoration in consultation with the FDA.

The 21st Century Cures Act

On December 13, 2016, President Obama signed the  21st Century Cures  Act, or  Cures Act,  into
law. The Cures Act is designed to modernize and personalize healthcare, spur innovation  and research,
and streamline the discovery and development of new therapies through increased federal funding of
particular programs. It authorizes increased funding for the  FDA to spend on innovation  projects.  The
new law also amends the Public Health Service  Act to reauthorize and expand  funding  for the  National
Institutes of Health. The Act establishes  the NIH Innovation Fund to pay for the cost of development
and implementation of a strategic plan, early stage investigators and  research. It also  charges  NIH with

leading and coordinating expanded pediatric research. Further, the Cures  Act directs the Centers for
Disease Control and Prevention to expand  surveillance of neurological diseases.

With amendments to the FDCA and the Public Health  Service Act, or PHSA, Title  III  of  the
Cures Act seeks to accelerate the discovery,  development, and delivery of new medicines  and medical
technologies. To that end, and among  other  provisions,  the Cures  Act reauthorizes the  existing priority
review voucher program for certain drugs  intended to treat rare pediatric diseases until 2020; creates a
new priority review voucher program  for  drug applications determined to  be  material  national security
threat medical countermeasure applications; revises the FDCA  to  streamline review  of  combination
product  applications; requires FDA to evaluate the potential use of ‘‘real  world  evidence’’ to help
support approval of new indications for  approved  drugs; provides a new ‘‘limited population’’ approval
pathway for antibiotic and antifungal  drugs intended to treat serious or life-threatening infections; and
authorizes FDA to designate a drug as  a  ‘‘regenerative advanced  therapy,’’  thereby  making it eligible
for certain expedited review and approval  designations.

Regulation Outside the United States

In order to market any product outside  of  the United  States,  a  company must also  comply with
numerous and varying regulatory requirements of  other  countries and  jurisdictions regarding  quality,
safety and efficacy and governing, among other things, clinical  trials, marketing authorization,
commercial sales and distribution of  drug products.  Whether or not it  obtains  FDA approval for a
product,  the company would need to  obtain the necessary approvals by the comparable foreign
regulatory authorities before it can commence clinical trials or marketing of the product in those
countries or jurisdictions. The approval  process ultimately  varies  between countries and jurisdictions
and can involve additional product testing  and additional  administrative review periods. The time
required to obtain approval in other  countries and jurisdictions  might differ from and be longer  than
that required to obtain FDA approval. Regulatory approval in one country or  jurisdiction does  not
ensure regulatory approval in another,  but  a failure or  delay in  obtaining regulatory approval in one
country or jurisdiction may negatively impact the regulatory process in others.

Regulation and Marketing Authorization  in  the European Union

The process governing approval of medicinal products in  the European Union follows essentially

the same lines as in the United States and, likewise, generally involves  satisfactorily completing each of
the following:

(cid:127) preclinical laboratory tests, animal  studies and formulation studies all performed in  accordance

with the applicable E.U. Good Laboratory  Practice regulations;

(cid:127) submission to the relevant national authorities of a clinical trial  application, or  CTA, which must

be approved before human clinical trials  may begin;

(cid:127) performance of adequate and well-controlled  clinical trials  to  establish the safety  and efficacy of

the product for each proposed indication;

(cid:127) submission to the relevant competent  authorities of a marketing authorization  application,  or

MAA, which includes the data supporting  safety and efficacy as well  as detailed information on
the manufacture and composition of the  product in  clinical  development  and proposed labelling;

(cid:127) satisfactory completion of an inspection by the relevant national authorities of the  manufacturing
facility or facilities, including those of  third parties, at  which the product  is produced  to  assess
compliance with strictly enforced cGMP;

(cid:127) potential audits of the non-clinical and  clinical trial sites that  generated the data in support of

marketing, sale or shipment of the product.

Preclinical Studies

Preclinical tests include laboratory evaluations of product  chemistry, formulation and stability, as

well as studies to evaluate toxicity in animal studies, in order to assess the potential safety and efficacy
of the product. The conduct of the preclinical  tests  and formulation  of  the compounds  for testing must
comply  with the relevant E.U. regulations and requirements.  The results of the preclinical tests,
together with relevant manufacturing information and analytical data, are submitted as part of the
CTA.

Clinical Trial Approval

Requirements for the conduct of clinical  trials in the European Union including  Good Clinical

Practice, or GCP, are set forth in the Clinical Trials Directive  2001/20/EC and the GCP Directive
2005/28/EC. Pursuant to Directive 2001/20/EC and  Directive 2005/28/EC,  as amended, a system for  the
approval of clinical trials in the European Union has been implemented through  national legislation of
the E.U. member states. Under this system, approval  must  be  obtained  from  the competent  national
authority of each E.U. member state  in which a study  is planned to be conducted.  To  this end, a CTA
is submitted, which must be supported  by an investigational medicinal product dossier, or IMPD, and
further supporting information prescribed by Directive  2001/20/EC and Directive  2005/28/EC and other
applicable guidance documents. Furthermore,  a clinical trial  may only be started after a competent
ethics committee has issued a favorable  opinion on  the clinical trial application in that country.

In April 2014, the E.U. passed the new Clinical  Trials Regulation, (EU) No 536/2014, which  will
replace the current Clinical Trials Directive 2001/20/EC.  To ensure  that the rules for clinical  trials are
identical throughout the European Union, the new  E.U. clinical  trials legislation was  passed  as a
regulation that is directly applicable in  all E.U. member  states. All clinical trials performed in  the
European Union are required to be  conducted in accordance  with the  Clinical Trials Directive
2001/20/EC until the new Clinical Trials  Regulation (EU) No 536/2014 becomes  applicable.  According
to the current plans of EMA, the new  Clinical Trials Regulation  will become applicable in  October
2018. The Clinical Trials Directive 2001/20/EC will, however, still apply  three years from the date of
entry into application of the Clinical  Trials Regulation to (i) clinical trials applications submitted  before
the entry into application and (ii) clinical  trials applications submitted within one year after the  entry
into application if the sponsor opts for  the old system.

The new Clinical Trials Regulation aims to simplify and  streamline  the approval of clinical trial in

the European Union. The main characteristics of the regulation  include:

(cid:127) a streamlined application procedure via a single entry point, the E.U.  portal;

(cid:127) a single set of documents to be prepared and submitted for the application as well as simplified
reporting procedures that will spare sponsors from submitting broadly identical  information
separately to various bodies and different member states;

(cid:127) a harmonized procedure for the assessment  of applications for  clinical trials, which  is divided in
two parts. Part I is assessed jointly by all member states  concerned. Part II  is assessed separately
by each member state concerned;

(cid:127) strictly defined deadlines for the assessment of clinical trial applications;  and

(cid:127) the involvement of the ethics committees in the assessment procedure in  accordance with the
national law of the member state concerned but within the overall timelines  defined  by  the
Clinical Trials Regulation.

Marketing Authorization

Authorization to market a product in  the member  states of  the  European  Union proceeds under

one of four procedures: a centralized authorization procedure, a mutual recognition  procedure, a
decentralized procedure or a national  procedure.

Centralized Authorization Procedure

The centralized procedure enables applicants  to  obtain  a marketing authorization that is valid in
all E.U. member states based on a single application. Certain medicinal products, including  products
developed by means of biotechnological  processes must undergo the centralized  authorization
procedure for marketing authorization, which, if granted  by  the European Commission, is automatically
valid in  all 28 E.U. member states. The EMA and the  European Commission administer this
centralized authorization procedure pursuant to Regulation (EC) No 726/2004.

Pursuant to Regulation (EC) No 726/2004, this  procedure  is mandatory  for:

(cid:127) medicinal products developed by means of  one  of the following biotechnological  processes:

(cid:127) recombinant DNA technology;

(cid:127) controlled expression of genes coding for biologically active proteins in prokaryotes and

eukaryotes including transformed mammalian  cells; and

(cid:127) hybridoma and monoclonal antibody  methods;

(cid:127) advanced therapy medicinal products as defined in Article  2 of Regulation (EC) No 1394/2007

on advanced therapy medicinal products;

(cid:127) medicinal products for human use containing  a new active substance that, on the date  of

effectiveness of this regulation, was not  authorized in  the European Union, and for which the
therapeutic indication is the treatment of any of the following diseases:

(cid:127) acquired immune deficiency syndrome;

(cid:127) cancer;

(cid:127) neurodegenerative disorder;

(cid:127) diabetes;

(cid:127) auto-immune diseases and other immune dysfunctions; and

(cid:127) viral diseases; and

(cid:127) medicinal products that are designated as orphan  medicinal products pursuant to Regulation

(EC) No  141/2000.

The centralized authorization procedure is optional  for other  medicinal  products  if they contain a

new active substance or if the applicant  shows that the medicinal product  concerned constitutes  a
significant therapeutic, scientific or technical  innovation or that the granting of  authorization is in  the
interest of patients in the European Union.

Administrative Procedure

Under the centralized authorization procedure, the EMA’s Committee for Medicinal Products  for

Human Use, or CHMP serves as the scientific  committee that renders opinions about  the safety,
efficacy and quality of medicinal products for  human use  on behalf of the EMA. The CHMP is
composed of experts nominated by each  member  state’s national authority for medicinal products, with
one of them appointed to act as Rapporteur for  the co-ordination  of the evaluation with the possible
assistance of a further member of the  Committee acting as a Co-Rapporteur. After approval, the

Rapporteur(s) continue to monitor the product  throughout its life cycle.  The  CHMP has 210 days,  to
adopt an opinion as to whether a marketing authorization should be granted. The process usually takes
longer in case additional information  is  requested, which  triggers clock-stops in  the procedural
timelines. The process is complex and involves extensive  consultation with the regulatory  authorities of
member states and a number of experts.  When  an application is submitted for  a marketing
authorization in respect of a drug that is  of major interest from the point of view of public health and
in particular from the viewpoint of therapeutic innovation, the  applicant may  pursuant to Article 14(9)
Regulation (EC) No 726/2004 request  an accelerated  assessment procedure. If the CHMP accepts such
request, the time-limit of 210 days will  be  reduced to 150 days  but it is possible that the CHMP can
revert to the standard time-limit for the  centralized procedure if  it considers that it is no longer
appropriate to conduct an accelerated assessment. Once the  procedure  is completed, a European Public
Assessment Report, or EPAR, is produced. If the opinion is  negative, information is  given as to the
grounds on which this conclusion was  reached. After the  adoption  of  the CHMP opinion, a  decision on
the MAA must be adopted by the European Commission,  after consulting the E.U.  member  states,
which  in total can take more than 60 days.

Conditional Approval

In specific circumstances, E.U. legislation (Regulation (EC)  No 726/2004  and Regulation (EC) No

507/2006 on Conditional Marketing Authorisations for Medicinal Products for  Human Use)  enables
applicants to obtain a conditional marketing authorization prior  to  obtaining the comprehensive clinical
data required for an application for a full marketing authorization.  Such  conditional approvals may be
granted for product candidates (including  medicines designated  as orphan  medicinal  products), if
(1) the risk-benefit balance of the product candidate  is positive, (2) it is  likely that the  applicant will be
in a position to provide the required  comprehensive clinical trial  data, (3) the product fulfills unmet
medical needs and (4) the benefit to public health of the immediate availability  on the  market of  the
medicinal product concerned outweighs  the risk inherent in the fact  that additional data are still
required. A conditional marketing authorization may contain specific obligations to be fulfilled by the
marketing authorization holder, including obligations with respect to the completion of  ongoing or  new
studies,  and with respect to the collection of  pharmacovigilance data. Conditional marketing
authorizations are valid for one year, and may be renewed  annually, if the risk-benefit  balance  remains
positive, and after an assessment of the need for  additional or modified conditions  and/or specific
obligations. The timelines for the centralized procedure described above  also apply  with respect to the
review by the CHMP of applications  for a conditional marketing  authorization.

Marketing Authorization Under Exceptional Circumstances

Under Regulation (EC) No 726/2004, products for which  the applicant  can demonstrate that
comprehensive data (in line with the requirements laid  down in Annex I of Directive 2001/83/EC, as
amended) cannot be provided (due to  specific reasons foreseen  in the legislation) might be eligible  for
marketing authorization under exceptional  circumstances.  This type of authorization is  reviewed
annually to reassess the risk-benefit balance. The fulfillment of any specific procedures/obligations
imposed as part of the marketing authorization under exceptional circumstances is  aimed at the
provision  of information on the safe and  effective use of the product and will normally not lead to the
completion of a full dossier/approval.

Market Authorizations Granted by Authorities  of E.U. Member States

In general, if the centralized procedure is  not  followed,  there are three alternative procedures to

obtain a marketing authorization in (one or several) E.U. member  states  as  prescribed in Directive
2001/83/EC:

(cid:127) The decentralized procedure allows applicants to file identical  applications  to  several E.U.

member states and receive simultaneous  national approvals based on the  recognition by E.U.
member states of an assessment by a  reference member  state.

(cid:127) The national procedure is only available for products  intended to be authorized in a  single E.U.

member state.

(cid:127) A mutual recognition procedure similar to the  decentralized  procedure is  available  when a
marketing authorization has already  been obtained in  at least  one  E.U.  member state.

A marketing authorization may be granted only to an applicant established  in the European

Union.

Pediatric Studies

Prior to obtaining a marketing authorization  in the European Union,  applicants have  to

demonstrate compliance with all measures included  in an EMA-approved Pediatric  Investigation  Plan,
or PIP, covering all subsets of the pediatric population, unless the  EMA has  granted a product-specific
waiver, a class waiver, or a deferral for  one or more of the measures included in  the PIP. The
respective requirements for all marketing  authorization procedures are set forth in Regulation (EC) No
1901/2006, which is referred to as the  Pediatric Regulation. This requirement also applies when  a
company wants to add a new indication,  pharmaceutical  form or route of administration for  a medicine
that is already authorized. The Pediatric Committee of the  EMA, or PDCO, may  grant deferrals for
some medicines, allowing a company  to  delay development  of the medicine  in children until  there is
enough information to demonstrate its  effectiveness and safety in  adults.  The PDCO may  also grant
waivers when development of a medicine  in children is  not needed  or  is not appropriate, such as for
diseases  that only affect the elderly population.

Before a marketing authorization application can be filed,  or an existing marketing  authorization

can be amended, the EMA determines  that companies actually comply with the agreed studies and
measures listed in each relevant PIP.

Period of Authorization and Renewals

A marketing authorization, other than  a conditional marketing authorization, is initially valid for

five years and the  marketing authorization may be renewed after five years on the basis of a
re-evaluation of the risk-benefit balance  by the EMA or by the competent authority of the authorizing
member state. To this end, the marketing authorization holder must provide the  EMA or the
competent authority with a consolidated version of the file in respect  of  quality, safety and efficacy,
including all variations introduced since  the marketing authorization was granted, at least six  months
before the marketing authorization ceases  to be valid. Once  renewed,  the marketing  authorization is
valid for an unlimited period, unless the  European Commission or the competent authority decides,  on
justified grounds relating to pharmacovigilance, to proceed with  one  additional five-year renewal. Any
authorization which is not followed by the actual placing of the drug  on the E.U.  market  (in  case of
centralized procedure) or on the market  of the  authorizing  member state within three years after
authorization ceases to be valid (the so-called  sunset  clause).

Regulatory Data Protection

European Union legislation also provides for a system  of  regulatory data  and market exclusivity.

According to Article 14(11) of Regulation (EC)  No  726/2004, as amended, and  Article 10(1) of
Directive 2001/83/EC, as amended, upon  receiving  marketing  authorization, new  chemical  entities
approved on the basis of complete independent data package benefit from eight years of data
exclusivity and an additional two years of market exclusivity. Data  exclusivity prevents  regulatory
authorities in the European Union from referencing  the innovator’s data  to assess  a generic
(abbreviated) application. During the additional two-year period of market exclusivity,  a generic
marketing authorization application can be submitted, and the innovator’s  data  may be referenced, but
no generic medicinal product can be marketed until the expiration of  the  market  exclusivity. The
overall ten-year period will be extended to a maximum of eleven years if, during the first eight  years  of
those ten years, the marketing authorization holder, or  MAH, obtains an authorization for one or more
new therapeutic indications which, during  the scientific evaluation  prior to their authorization, are  held
to bring a significant clinical benefit in  comparison with existing  therapies. Even if  a compound is
considered to be a new chemical entity and the innovator is able to gain the  period of  data  exclusivity,
another company nevertheless could  also  market  another  version of  the  drug if  such company  obtained
marketing authorization based on an  MAA with  a complete independent data package of
pharmaceutical test, preclinical tests and clinical trials.

Transparency

There is  an increasing trend in the E.U. towards greater transparency and, while the
manufacturing or quality information in marketing authorization dossiers is currently generally
protected as confidential information,  the EMA and  national regulatory  authorities  are now liable to
disclose much of the non-clinical and  clinical information, including the full  clinical study reports, in
response to freedom of information requests  after the marketing authorization has been  granted. In
October 2014, the EMA adopted a policy under which  clinical study reports would  be  posted on the
agency’s website following the grant,  denial or withdrawal  of  a marketing authorization application,
subject to procedures for limited redactions and protection against unfair commercial use. Additional
transparency provisions are contained  in the  new Clinical Trials Regulation  (EU) No 536/2014 that will
take effect in May 2016 at the earliest.

Regulatory Requirements After a Marketing  Authorization  has  been  Obtained

If we  obtain authorization for a medicinal  product in the  European  Union, we  will  be  required to

comply  with a range of requirements applicable to the manufacturing, marketing, promotion and sale of
medicinal products:

Pharmacovigilance and Other Requirements

We  will, for example, have to comply  with the E.U.’s stringent pharmacovigilance or safety

reporting rules, pursuant to which post-authorization studies and  additional monitoring obligations  can
be imposed. E.U. regulators may conduct inspections to verify our compliance with applicable
requirements, and we will have to continue  to  expend time,  money and effort  to  remain compliant.
Non-compliance with E.U. requirements regarding  safety monitoring or pharmacovigilance, and with
requirements related to the development  of  products for the  pediatric  population, can also result in
significant financial penalties in the European Union.  Similarly, failure to comply  with the European
Union’s requirements regarding the protection  of  individual personal data can also lead  to  significant
penalties and sanctions. Individual E.U.  member states may also impose  various sanctions and penalties
in case we do not comply with locally applicable requirements.

Manufacturing

The manufacturing of authorized drugs, for  which a separate manufacturer’s  license is mandatory,

must be conducted in strict compliance  with the EMA’s  GMP requirements  and comparable
requirements of other regulatory bodies  in  the European  Union, which mandate the methods,  facilities
and controls used in manufacturing, processing and  packing  of drugs to assure their safety and identity.
The EMA enforces its GMP requirements through mandatory  registration of facilities and inspections
of those facilities. The EMA may have a  coordinating role for these  inspections while the  responsibility
for carrying them out rests with the member states competent authority under  whose  responsibility the
manufacturer falls. Failure to comply with  these requirements could  interrupt  supply and result in
delays, unanticipated costs and lost revenues,  and  could subject the applicant to potential legal or
regulatory action, including but not limited to warning letters,  suspension of manufacturing, seizure of
product,  injunctive action or possible civil  and criminal penalties.

Marketing and Promotion

The marketing and promotion of authorized drugs, including industry-sponsored continuing
medical education and advertising directed toward  the prescribers of drugs and/or the  general public,
are strictly regulated in the European Union under  Directive 2001/83EC, as amended. The applicable
regulations aim to ensure that information provided by  holders of marketing authorizations regarding
their products is truthful, balanced and  accurately reflects the  safety and efficacy  claims authorized  by
the EMA or by the competent authority of the authorizing member  state. Failure  to  comply with these
requirements can result in adverse publicity, warning letters, corrective  advertising and  potential  civil
and criminal penalties.

Patent Term Extension

To compensate the patentee for delays in obtaining  a marketing authorization for a patented
product,  a supplementary certificate, or  SPC,  may  be  granted extending  the exclusivity period for  that
specific  product by up to five years. Applications  for SPCs  must be made to the  relevant patent office
in each E.U. member state and the granted certificates  are valid only  in the member state of grant. An
application has to be made by the patent  owner  within six months  of  the first marketing  authorization
being granted in the European Union (assuming the  patent  in question has not expired,  lapsed or  been
revoked) or within six months of the  grant of the patent (if  the marketing authorization is  granted
first). In the context of SPCs, the term  ‘‘product’’  means the active ingredient or combination  of  active
ingredients for a medicinal product and the term ‘‘patent’’ means a patent protecting such a  product or
a new manufacturing process or application  for  it. The duration of  an  SPC  is calculated as the
difference between the patent’s filing  date and the date of the first  marketing authorization,  minus five
years, subject to a maximum term of five years.

A six-month pediatric extension of an  SPC may be obtained  where the patentee has carried out an

agreed pediatric investigation plan, the  authorized product information includes information on  the
results of the studies and the product is authorized in  all member  states  of  the European  Union.

Brexit and the Regulatory Framework in the  United Kingdom

On June 23, 2016, the electorate in the United Kingdom  voted in  favor of leaving the European

Union  (commonly referred to as ‘‘Brexit’’). The  withdrawal  of the U.K. from the European Union  will
take effect either on the effective date  of  the  withdrawal agreement or, in the absence of agreement,
two years after the U.K. provides a notice of withdrawal pursuant to the E.U. Treaty. The U.K. Prime
Minister has stated that notice of withdrawal  will  be  given by the end of March 2017.  As the regulatory
framework for pharmaceutical products  in  the U.K.  covering  quality, safety and efficacy of
pharmaceutical products, clinical trials, marketing authorization,  commercial sales and  distribution of
pharmaceutical products is derived from European Union  directives  and regulations, Brexit could

materially impact the future regulatory regime which  applies to products and  the approval of product
candidates in the U.K. It remains to  be  seen how,  if at all, Brexit will impact regulatory  requirements
for product candidates and products in the  U.K and  the European Union.

Pharmaceutical Coverage, Pricing and Reimbursement

In the United States and markets in other countries, patients  who are prescribed  treatments for
their conditions and providers performing  the prescribed services generally  rely on third-party  payors to
reimburse all or part of the associated  healthcare costs.  Significant uncertainty  exists as  to  the coverage
and reimbursement status of products approved by the FDA and  other government authorities. Thus,
even if a product candidate is approved, sales of the product will  depend, in  part, on the extent  to
which  third-party payors, including government health  programs in the United  States such as  Medicare
and Medicaid, commercial health insurers and managed care organizations, provide coverage, and
establish adequate reimbursement levels  for, the  product. The process for determining whether  a payor
will provide coverage for a product may be separate  from the process for setting  the price or
reimbursement rate that the payor will  pay for the  product once  coverage is approved. Third-party
payors are increasingly challenging the prices charged, examining the medical necessity, and reviewing
the cost-effectiveness of medical products  and services and imposing  controls to manage costs.  Third-
party payors may limit coverage to specific products on  an approved  list,  also known as a formulary,
which  might not include all of the approved products  for a  particular indication.

To secure coverage and reimbursement for any product  that might be approved for sale, a

company may need to conduct expensive  pharmacoeconomic studies in order to demonstrate the
medical necessity and cost-effectiveness of  the product, in addition to the costs required to obtain FDA
or other  comparable marketing approvals.  Nonetheless, product candidates may not be considered
medically necessary or cost effective. A decision by a  third-party payor not to cover a product candidate
could reduce physician utilization once the product is approved  and have a material adverse effect on
sales, results of operations and financial  condition. Additionally, a payor’s decision to provide coverage
for a product does not imply that an  adequate reimbursement rate will be approved.  Further,  one
payor’s determination to provide coverage for a  drug product does not assure that other payors will
also provide coverage and reimbursement  for the  product, and the level of coverage and
reimbursement can differ significantly from payor to payor.

The containment of healthcare costs also has become a  priority of federal, state  and foreign

governments and the prices of drugs have been a focus in this effort. Governments have  shown
significant interest in implementing cost-containment programs, including price controls,  restrictions on
reimbursement and requirements for substitution  of  generic products.  Adoption of price  controls and
cost-containment measures, and adoption of  more  restrictive policies in  jurisdictions with existing
controls and measures, could further limit  a company’s revenue generated from  the sale  of any
approved products. Coverage policies  and  third-party reimbursement  rates  may change at  any time.
Even if favorable coverage and reimbursement status  is attained for one or more  products for which  a
company or its collaborators receive marketing  approval, less favorable  coverage policies and
reimbursement rates may be implemented in the  future.

Outside the United States, ensuring adequate coverage and payment  for a  product also involves
challenges. Pricing of prescription pharmaceuticals  is subject to governmental control in many  countries.
Pricing negotiations with governmental  authorities can  extend  well beyond  the receipt of regulatory
marketing approval for a product and  may  require a clinical trial that compares  the cost effectiveness
of a product to other available therapies. The conduct of such  a  clinical trial could be expensive and
result in delays in commercialization.

In the European Union, pricing and reimbursement schemes  vary  widely from country to country.

Some countries provide that products  may be marketed only after  a  reimbursement price  has been
agreed. Some countries may require the  completion of additional  studies that compare the

cost-effectiveness of a particular drug  candidate to currently available therapies  or so  called health
technology assessments, in order to obtain reimbursement  or pricing approval. For example, the
European Union provides options for  its  member states to restrict the  range of products for  which their
national health insurance systems provide  reimbursement and  to  control the prices of medicinal
products for human use. E.U. European Union member states  may  approve a specific price for a
product  or it may instead adopt a system  of direct  or indirect controls on  the profitability of the
company placing the product on the  market.  Other  member states allow companies to fix their own
prices for products, but monitor and  control  prescription  volumes  and issue guidance to physicians to
limit prescriptions. Recently, many countries  in the European Union  have increased the amount of
discounts required on pharmaceuticals  and these efforts could  continue as countries  attempt  to  manage
healthcare expenditures, especially in  light of the  severe fiscal and  debt  crises experienced by many
countries in the European Union. The downward pressure on  health care  costs in  general, particularly
prescription drugs, has become intense. As  a result, increasingly high barriers are being erected to the
entry of new products. Political, economic and regulatory developments may further complicate pricing
negotiations, and pricing negotiations  may continue after reimbursement has  been obtained. Reference
pricing used by various European Union member  states, and parallel trade, i.e., arbitrage between
low-priced and high-priced member states, can further  reduce prices.  There can  be  no assurance  that
any country that has price controls or  reimbursement limitations for pharmaceutical products  will allow
favorable reimbursement and pricing  arrangements for  any products, if approved  in those  countries.

Healthcare Law and Regulation

Healthcare providers and third party payors  play  a primary  role  in the recommendation and
prescription of drug products that are granted  marketing approval. Arrangements with  providers,
consultants, third party payors and customers are subject  to broadly  applicable  fraud and abuse,
anti-kickback, false claims laws, reporting of payments to physicians and teaching physicians and patient
privacy laws and regulations and other healthcare laws  and regulations that may constrain business
and/or financial arrangements. Restrictions under  applicable  federal and state healthcare laws and
regulations, include the following:

(cid:127) the federal Anti-Kickback Statute  prohibits, among other things, persons and entities from

knowingly and willfully soliciting, offering, paying,  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, in whole or in part, under a federal healthcare  program  such as Medicare and  Medicaid;

(cid:127) the federal civil and criminal false  claims laws,  including the  civil  False Claims Act  and civil

monetary penalty laws, which prohibit  individuals or entities  from,  among  other things,
knowingly presenting, or causing to be presented, to the federal government,  claims for  payment
that are false, fictitious or fraudulent or knowingly making, using or causing to be made  or used
a false record or statement to avoid, decrease or conceal an obligation to pay  money to the
federal government;

(cid:127) the federal Health Insurance Portability and Accountability Act of  1996, or HIPAA, which
created additional federal criminal laws that prohibit, among other things, knowingly and
willfully executing, or attempting to execute, a scheme to defraud any healthcare  benefit
program or making false statements relating to healthcare matters;

(cid:127) HIPAA, as amended by the Health  Information  Technology  for Economic and  Clinical  Health
Act and their regulations, including the  Final Omnibus Rule published in January 2013,  which
impose obligations, including mandatory contractual terms, with respect to safeguarding the
privacy, security and transmission of individually identifiable  health  information;

(cid:127) the federal false statements statute, which prohibits  knowingly and willfully falsifying, concealing
or covering up a material fact or making any  materially false statement in connection with the
delivery of or payment for healthcare  benefits, items or services;

(cid:127) the federal transparency requirements known as  the federal Physician Payments Sunshine Act,

under the Patient Protection and Affordable Care Act, as  amended by the Health  Care
Education Reconciliation Act, or the  Affordable Care Act, which  requires certain manufacturers
of drugs, devices, biologics and medical supplies to report annually  to  the Centers for
Medicare & Medicaid Services, or CMS, within  the United  States Department of  Health and
Human Services, information related to payments and other  transfers of  value made by that
entity to physicians and teaching hospitals, as well as ownership and investment interests held by
physicians and their immediate family members; and

(cid:127) analogous state  and foreign laws and  regulations, such  as state  anti-kickback and  false claims

laws, which may apply to healthcare items or  services that  are reimbursed  by  non-governmental
third-party payors, including private insurers.

Some state laws require pharmaceutical companies to comply with  the pharmaceutical  industry’s

voluntary compliance guidelines and the relevant  compliance guidance  promulgated  by  the federal
government in addition to requiring drug manufacturers to  report information related  to  payments to
physicians and other health care providers or marketing  expenditures.  State and foreign laws also
govern the privacy and security of health  information  in some  circumstances, many of which  differ  from
each  other in significant ways and often  are not preempted  by HIPAA, thus complicating compliance
efforts.

Healthcare Reform

A primary trend in the United States healthcare  industry  and  elsewhere is cost containment. There

have been a number of federal and state proposals during the  last few  years regarding the pricing of
pharmaceutical and biopharmaceutical products, limiting coverage and reimbursement for drugs and
other medical products, government control and other changes to the healthcare system in the  United
States.

In March 2010, the United States Congress  enacted the  Affordable Care Act, or the  ACA, which,

among other things, includes changes to the  coverage and payment for products under government
health care programs. Among the provisions of the Affordable Care Act of importance  to  potential
drug candidates are:

(cid:127) an annual, nondeductible fee on any entity that manufactures  or imports  specified branded
prescription drugs and biologic agents, apportioned among these entities according  to  their
market share in certain government healthcare programs, although  this fee would not apply to
sales of certain products approved exclusively for orphan indications;

(cid:127) expansion of eligibility criteria for Medicaid programs by,  among other things, allowing states  to
offer Medicaid coverage to certain individuals  with income at  or below 133% of the  federal
poverty level, thereby potentially increasing a manufacturer’s  Medicaid rebate liability;

(cid:127) expanded manufacturers’ rebate liability under  the Medicaid Drug Rebate Program by increasing
the minimum rebate for both branded and generic  drugs  and revising  the definition of  ‘‘average
manufacturer price,’’ or AMP, for calculating and  reporting Medicaid drug rebates on outpatient
prescription drug prices and extending  rebate liability to prescriptions  for individuals  enrolled in
Medicare Advantage plans;

(cid:127) addressed a new methodology by which rebates  owed by manufacturers under  the Medicaid

Drug Rebate Program are calculated for  drugs  that  are inhaled, infused, instilled,  implanted or
injected;

(cid:127) expanded the types of entities eligible  for  the 340B drug discount  program;

(cid:127) established the Medicare Part D coverage gap  discount program by requiring  manufacturers  to

provide a 50% point-of-sale-discount  off the  negotiated price  of  applicable  brand drugs to
eligible beneficiaries during their coverage  gap  period as  a condition for the manufacturers’
outpatient drugs to be covered under  Medicare Part D;

(cid:127) a new  Patient-Centered Outcomes  Research Institute to oversee, identify priorities in,  and
conduct comparative clinical effectiveness research, along  with funding for such research;

(cid:127) the Independent Payment Advisory Board,  or IPAB, which  has authority to recommend certain
changes to the Medicare program to reduce expenditures by the program that could result  in
reduced payments  for prescription drugs. However, the  IPAB implementation  has been  not  been
clearly defined. PPACA provided that  under certain circumstances, IPAB recommendations will
become law unless Congress enacts legislation that will achieve  the  same or greater Medicare
cost savings; and

(cid:127) established the Center for Medicare  and  Medicaid Innovation within  CMS to test  innovative
payment and service delivery models to lower Medicare  and Medicaid spending, potentially
including prescription drug spending.  Funding has been allocated to support the mission  of  the
Center for Medicare and Medicaid Innovation from  2011 to 2019.

Other legislative changes have been proposed and adopted in the United States since  the ACA was

enacted.  For example, in August 2011,  the Budget Control Act of 2011,  among  other  things,  created
measures for spending reductions by Congress.  A Joint  Select Committee on Deficit Reduction,  tasked
with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2012 through  2021,
was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several
government programs. This includes  aggregate reductions of  Medicare payments to providers of up to
2% per  fiscal year, which went into effect  in April 2013 and will remain in effect  through 2024 unless
additional Congressional action is taken. In January  2013, President Obama signed into law the
American Taxpayer Relief Act of 2012,  which,  among  other  things, further  reduced  Medicare payments
to several providers, including hospitals, imaging centers and cancer treatment  centers,  and increased
the statute of limitations period for the government to recover overpayments  to  providers  from three to
five years.

With the new Administration and Congress, there will likely be additional legislative changes,
including repeal and replacement of  certain provisions  of  the ACA. In January 2017, Congress voted to
adopt a budget resolution for fiscal year 2017,  or the Budget Resolution, that authorizes the
implementation of legislation that would repeal portions of the ACA. The Budget  Resolution is  not  a
law, however, it is widely viewed as the first step toward  the passage of legislation  that  would repeal
certain aspects of the ACA. Further, on  January  20, 2017, President Trump signed an Executive Order
directing federal agencies with authorities  and  responsibilities under the  ACA to waive, defer, grant
exemptions from, or delay the implementation of any provision  of the ACA that would  impose a fiscal
or regulatory burden on states, individuals, healthcare providers, health insurers, or manufacturers of
pharmaceuticals or medical devices. In  March 2017, the  United States House  of  Representatives
introduced a Budget Resolution to replace the ACA will a tax credit based system. It is  uncertain if
these changes will be approved by the  United States Senate  or  the President.

The President and congressional leaders have expressed interest in repealing  certain  ACA
provisions and replacing them with alternatives that may be less costly and  provide state  Medicaid
programs and private health plans more flexibility. It is possible that  these repeal and replacement
initiatives, if enacted into law, could ultimately result in fewer individuals having  health  insurance
coverage or in individuals having insurance coverage with less generous benefits.  The  scope of potential
future legislation to repeal and replace  ACA provisions is highly uncertain  in many respects, and  it is
possible that some of the ACA provisions  that generally are not favorable for  the research-based

pharmaceutical industry could also be repealed along  with ACA coverage expansion  provisions.
However, at this time the coverage expansion provisions of the ACA appear  most likely to be repealed
and replaced.

Employees

As of March 15, 2017, we had 59 employees,  38 of our employees are located in  Vienna,  Austria
and 21 of our employees were located in  King of  Prussia, Pennsylvania. Our employees in Austria  are
subject to the collective bargaining agreement  of the chemical industry. This is an  annual agreement
between the employer representatives and  the trade  union of an industry. It  defines conditions of
employment, such as minimum wages,  working hours and conditions, overtime payments,  vacations and
other matters. We do not have a works council, which would require employee  representatives on  our
supervisory board.

We  consider our relations with our employees  to  be  good.

Our Corporate Information

We  were incorporated in October 2005  in Austria under  the name Nabriva  Therapeutics
Forschungs GmbH, a limited liability company organized  under Austrian law, as  a spin-off from
Sandoz GmbH and commenced operations  in February 2006.  In 2007, we transformed  into  a stock
corporation (Aktiengesellschaft) under the name Nabriva Therapeutics AG.  We  are incorporated under
the laws of the Republic of Austria and  registered at the Commercial Register of the  Commercial
Court of Vienna. Our executive offices are located  at Leberstrasse 20,  1110 Vienna,  Austria, and our
telephone number is +43 (0)1 740 930. Our  U.S. operations are conducted by our wholly-owned
subsidiary Nabriva Therapeutics US, Inc.,  a  Delaware corporation established in August 2014  and
located at 1000 Continental Drive, Suite  600, King  of Prussia, PA  19406. Our website address is

form part of this Annual Report. Our  agent for service of  process in  the United  States  is CT
Corporation System, 111 Eighth Avenue, New York,  New  York 10011.

On March 24, 2017, our supervisory board authorized  management to pursue a  plan for the

redomiciliation of our ultimate parent  company from  Austria to Ireland. We  are working  with our
advisors to structure and implement  such a redomiciliation plan. We currently anticipate that the  plan,
which  will require further approval of  the  supervisory  board,  will be presented to our shareholders  for
their consideration during 2017. We may  abandon  our redomiciliation plan at any time and  there can
be no assurance that we will redomicile from Austria to Ireland during  2017, or at all.

ITEM 1A. RISK FACTORS

You should consider carefully the risks  and uncertainties described below, together with all of  the other
information in this Form 10-K. If any of  the following risks are realized, our business, financial condition,
results of operations and prospects could be materially and adversely affected. The  risks  described below are
not  the only risks facing us. Risks and  uncertainties  not  currently known  to us  or that we currently  deem to  be
immaterial also may materially adversely affect our business, financial  condition, results of operations and/or
prospects.

Risks Related to Our Financial Position and Need for Additional Capital

We have  incurred significant losses since  our  inception. We expect to incur losses for at least the next several
years and may never generate profits from operations or maintain profitability.

Since inception, we have incurred significant operating losses. Our  net losses  were $54.9  million  for

the year ended December 31, 2016, $47.0  million for the year ended December 31,  2015 and
$14.2 million for the year ended December 31, 2014.  As of December 31,  2016, we  had accumulated
losses of $204.8 million. To date, we have  financed our operations  primarily through the sale of our
equity securities, including our American  Depositary Shares, or ADSs, and private placements of our
common shares, convertible loans and research  and development  support from governmental  grants
and loans. We have devoted substantially all of  our  efforts to  research and development, including
clinical trials. We have not completed  development of any drugs. We expect to continue to incur
significant expenses and increasing operating losses  for at least the next several years. The net  losses  we
incur may fluctuate significantly from quarter-to-quarter and year-to-year.

We  anticipate that our expenses will increase substantially as we progress  our two international

Phase 3 clinical trials of our lead product  candidate, lefamulin, for the treatment  of community-
acquired bacterial pneumonia, or CABP. We  initiated the first of these clinical trials, which  we refer to
as LEAP 1, in September 2015 and initiated  the second trial, which  we  refer  to  as LEAP 2, in April
2016. If the results of these two trials are favorable,  including  achievement of the  primary  efficacy
endpoints of the trials, we expect to submit applications  for  marketing approval for  lefamulin  for the
treatment of CABP in both the United States  and Europe in  2018. We also continue to characterize
the clinical pharmacology of lefamulin.  If  we obtain marketing approval of lefamulin for CABP or
another indication, we also expect to  incur significant sales, marketing, distribution  and manufacturing
expenses.

In addition, our expenses will increase if and as we:

(cid:127) initiate or continue the research and development  of  lefamulin for additional indications and of

our  other product candidates;

(cid:127) seek to discover and develop additional product candidates;

(cid:127) seek marketing approval for any product candidates that successfully complete clinical

development;

(cid:127) ultimately establish a sales, marketing and distribution infrastructure and  scale up manufacturing
capabilities to commercialize any product candidates for  which we receive marketing approval;

(cid:127) in-license or acquire other products,  product candidates  or technologies;

(cid:127) maintain, expand and protect our intellectual property  portfolio;

(cid:127) expand our physical presence in the United States; and

(cid:127) add operational, financial and management information  systems and personnel, including

personnel to support our product development,  our  operations  as a public company and our
planned future commercialization efforts.

Our ability to generate profits from operations  and remain profitable depends on our  ability to

successfully develop and commercialize drugs that  generate  significant revenue. Based on our current
plans, we do not expect to generate significant revenue unless  and until we obtain marketing approval
for, and commercialize, lefamulin. We  do  not expect  to  obtain  marketing  approval before 2019, if at  all.
This will require us to be successful in  a  range  of  challenging activities,  including:

(cid:127) completing enrollment for our Phase  3 clinical trials of lefamulin  for the  treatment of CABP and

completing both trials as and when we expect;

(cid:127) obtaining favorable results from our Phase 3 clinical trials of lefamulin for  the treatment of

CABP;

(cid:127) subject to obtaining favorable results from  our  Phase 3  clinical trials, applying for and obtaining

marketing approval for lefamulin;

(cid:127) establishing sales, marketing and distribution capabilities to effectively  market and sell lefamulin

in the United States;

(cid:127) establishing collaboration, distribution  or other marketing arrangements with third parties  to

commercialize lefamulin in markets outside the  United States;

(cid:127) protecting our rights to our intellectual property portfolio related to lefamulin;

(cid:127) contracting for the manufacture of  and obtaining commercial quantities  of  lefamulin; and

(cid:127) negotiating and securing adequate reimbursement from third-party  payors for  lefamulin.

We  may never succeed in these activities and,  even  if we do,  may  never generate revenues  that  are
significant enough to generate profits from operations. Even  if we do  generate profits from operations,
we may not be able to sustain or increase  profitability on a quarterly  or  annual  basis. Our failure to
generate profits from operations and remain profitable would decrease the value of our company  and
could impair our ability to raise capital, expand our business, maintain our research and development
efforts, diversify our product offerings or continue our operations. A decline in  the value  of our
company could also cause our shareholders to lose  all  or part  of their investment.

We will need substantial additional funding.  If  we are unable to raise capital  when needed or on acceptable
terms, we could be forced to delay, reduce  or  eliminate  our  product development  programs  or future
commercialization efforts.

We  expect our research and development, commercialization and other  expenses to increase
substantially in connection with our ongoing activities,  particularly  as we continue development of and
potentially seek marketing approval for  lefamulin  and,  possibly, other  product candidates  and continue
our  research activities. Our expenses  will  increase if we suffer any delays  in  our  Phase 3  clinical
program for lefamulin for CABP, including delays in enrollment  of  patients. If we obtain marketing
approval for lefamulin or any other product candidate that we develop, we expect  to  incur  significant
commercialization expenses related to product sales,  marketing, distribution and manufacturing.

Furthermore, we expect to continue to incur  additional costs associated with operating as a  public

company.

Accordingly, we will need to obtain substantial additional  funding in connection  with our

continuing operations. If we are unable  to  raise capital  when needed or  on attractive terms, we could

be forced to delay, reduce or eliminate  our research and development programs or  any future
commercialization efforts.

We  expect that our existing cash, cash equivalents and short-term  investments, will be sufficient  to
enable us to fund our operating expenses  and capital expenditure requirements  at least into the  second
quarter of 2018 and to obtain top-line  data  for both our  Phase 3 clinical trials of lefamulin. We have
based these estimates on assumptions  that may prove to be wrong, and we could use our capital
resources sooner than we currently expect. These  estimates  assume,  among other  things, that we do not
obtain any additional funding through  grants and  clinical trial  support, collaboration agreements  or
debt financings.

Our future capital requirements will depend on many  factors, including:

(cid:127) the progress, costs and results of our ongoing Phase  3 clinical trials of lefamulin;

(cid:127) the costs and timing of process development and  manufacturing scale-up activities associated

with lefamulin;

(cid:127) the costs, timing and outcome of regulatory  review of lefamulin;

(cid:127) the costs of commercialization activities  for  lefamulin if  we receive, or expect to receive,

marketing approval, including the costs  and timing  of  establishing product  sales,  marketing,
distribution and outsourced manufacturing capabilities;

(cid:127) subject to receipt of marketing approval, revenue received from commercial sales of lefamulin;

(cid:127) the costs of developing lefamulin for  the treatment  of  additional  indications;

(cid:127) our ability to establish collaborations on favorable terms, if at all;

(cid:127) the scope, progress, results and costs of product  development of BC-7013  and any other product

candidates that we may develop;

(cid:127) the extent to which we in-license or acquire  rights to other products, product  candidates or

technologies;

(cid:127) the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our

intellectual property rights and defending  against intellectual property-related claims;

(cid:127) the continued availability of Austrian governmental grants;

(cid:127) the rate of the expansion of our physical  presence in  the United  States; and

(cid:127) the costs of operating as a public company in  the United  States.

Conducting clinical trials is a time consuming, expensive and uncertain process that takes years to

complete, and we may never generate the  necessary data or results required to obtain marketing
approval and achieve product sales. Our  commercial revenues, if any, will be derived from  sales  of
lefamulin or any other products that we  successfully develop, none of which we expect  to  be
commercially available for several years,  if at all. In addition, if  approved,  lefamulin  or any  other
product  candidate that we develop, in-license  or acquire  may  not  achieve commercial success.
Accordingly, we will need to obtain substantial additional  financing to achieve our business objectives.

Adequate additional financing may not be available to us on acceptable terms, or at all. In

addition, we may seek additional capital due to favorable market conditions or  strategic considerations,
even if we believe  that we have sufficient  funds for our current or future  operating plans.

Raising additional capital may cause dilution  to our security holders, restrict our  operations or  require us  to
relinquish rights to our technologies or product candidates.

Until such time, if ever, as we can generate  substantial product revenues, we expect to finance our
cash needs through a combination of equity  offerings,  debt  financings, collaborations, and funding from
local and international government entities and non-government organizations in the disease areas
addressed by our product candidates and  marketing, distribution or licensing arrangements. To  the
extent that we raise additional capital  through the  sale of equity  or convertible  debt  securities, your
ownership interest will be diluted, and  the terms  of these  securities may include liquidation  or other
preferences that adversely affect your rights as a  security holder. Debt  financing, if available, may
involve agreements that include covenants limiting or restricting our ability to take  specific actions, such
as incurring additional debt, making capital expenditures or declaring dividends. In addition, debt
service obligations under any debt financings may limit the availability of our  cash for other purposes,
and we may be unable to make interest  payments or repay the principal of such debt  financings when
due.

If we  raise additional funds through collaborations, strategic  alliances or marketing,  distribution or
licensing arrangements with third parties,  we may have to relinquish  valuable rights to our  technologies,
future revenue streams, research programs  or product candidates or to 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 limited operating history may make  it difficult for you to  evaluate the success of our  business to date and
to assess our future viability.

Our operations to date have been limited to organizing  and staffing our  company, developing and

securing our technology, raising capital  and undertaking  preclinical studies  and clinical trials of our
product  candidates. We have not yet demonstrated our ability to successfully complete  development of
any product candidates, obtain marketing  approvals, manufacture a commercial scale product, or
arrange for a third party to do so on  our behalf, or conduct sales and  marketing  activities necessary for
successful product commercialization. Consequently, any predictions  you  make about our future  success
or viability may not be as accurate as  they  could be if we had a longer  operating history.

In addition, as a new business, we may  encounter unforeseen expenses, difficulties, complications,

delays and other known and unknown  factors.  We will need to transition from a  company with  a
research and development focus to a company  capable of  supporting commercial activities.  We may  not
be successful in such a transition.

We have  relied on, and expect to continue  to  rely  on, certain government grants and funding from the
Austrian government. Should these funds cease to be  available, or our  eligibility be reduced, or if we are
required to repay any of these funds, this could  impact our ongoing need for funding  and the timeframes
within which we currently expect additional funding will be required.

As a company that carries out extensive research and development  activities, we benefit from the
Austrian research and development support regime, under which  we  are  eligible to receive a  research
premium from the Austrian government  equal to 12% (10%, in  the case of fiscal years prior  to  2016)
of a specified research and development  cost base. Qualifying expenditures  largely comprise  research
and development activities conducted  in Austria, however, the research premium  is also  available  for
certain related third-party expenses with  additional limitations. We  received research premiums of
$4.3 million for the year ended December 31, 2015  and  $1.4  million  for  the year  ended December 31,
2014. We also expect to receive a research premium  for our  qualified 2016 expenditures. However,  as

we increase our personnel and expand  our business outside of Austria, we may  not  be  able to continue
to claim research premiums to the same extent as we  have in previous years,  as some research and
development activities may no longer be considered to occur in Austria. As  research  premiums that
have been paid out already may be audited by the  tax authorities,  there is a  risk that parts of the
submitted cost base may not be considered as eligible and therefore  repayments may  have to be made.

Risks Related to Product Development and Commercialization

We depend heavily on the success of our  lead product candidate, lefamulin, which  we are developing for CABP
and other indications. If we are unable  to  complete our Phase 3 clinical program for lefamulin for CABP as
and when expected and obtain marketing approvals for  lefamulin,  or if thereafter we fail to commercialize
lefamulin or experience significant delays in  doing so, our business  will  be materially harmed.

We  have invested a significant portion of our efforts and financial resources in the development of
lefamulin. There remains a significant  risk that we will  fail to successfully develop lefamulin for CABP
or any other indication. Based on our  estimates regarding patient enrollment, we expect to have
top-line  data from  LEAP 1 in the third quarter of 2017.  With respect to LEAP 2, based on current
projections, we expect to complete patient  enrollment in the fourth quarter of 2017,  and we anticipate
receiving top-line data for LEAP 2 in  the first  quarter of 2018. Our ability to meet our target timing
will depend on our enrollment rates.  A  significant delay  in enrollment would result in delays to our
development timeline and additional development  costs beyond  what  we  have budgeted. If  we
ultimately obtain favorable results from  our Phase  3 clinical  program  for  lefamulin  for CABP, we  do
not expect to submit applications for marketing approval for lefamulin for this indication  until 2018.

Our ability to generate product revenues,  which may  not  occur for several  years,  if ever, will
depend  heavily on our obtaining marketing approval for and commercializing lefamulin. The success of
lefamulin will depend on a number of factors, including  the following:

(cid:127) completing our ongoing Phase 3 clinical trials as and when expected;

(cid:127) obtaining favorable results from clinical trials;

(cid:127) making arrangements with third-party manufacturers for commercial supply and receiving

regulatory approval of our manufacturing processes and our third-party manufacturers’ facilities
from applicable regulatory authorities;

(cid:127) receipt of marketing approvals from applicable  regulatory authorities  for  lefamulin  for the

treatment of CABP;

(cid:127) launching commercial sales of lefamulin, if and when  approved, whether alone or  in

collaboration with third parties;

(cid:127) acceptance of lefamulin, if and when  approved, by patients, the  medical community and  third-

party payors;

(cid:127) effectively competing with other therapies;

(cid:127) maintaining a continued acceptable  safety profile  of lefamulin following approval;

(cid:127) obtaining and maintaining patent and trade  secret  protection and regulatory  exclusivity; and

(cid:127) protecting our rights in our intellectual property portfolio.

Successful development of lefamulin  for the treatment of additional indications,  if any, or for use

in other patient populations and our  ability, if it  is approved, to broaden the label for  lefamulin  will
depend  on similar factors.

If we  do not achieve one or more of  these factors in a timely  manner  or  at all, we could

experience significant delays or an inability to successfully commercialize lefamulin for CABP  or for
any additional indications, which would materially harm our business.

If clinical trials of lefamulin or any of our other product candidates fail to demonstrate safety and efficacy to
the satisfaction of the U.S. Food and Drug Administration, or FDA, regulatory authorities  in the European
Union, or other regulatory authorities or do not otherwise produce favorable results, we  may incur  additional
costs or experience delays in completing, or  ultimately be unable to complete,  the development and
commercialization of lefamulin or any other product candidate.

Before obtaining marketing approval from regulatory authorities for the sale of any product
candidate, we must complete preclinical  development and early clinical  trials, including Phase  1 clinical
trials, in addition to extensive later-stage Phase 3  clinical  trials, to demonstrate  the safety and efficacy
of our product candidates in humans.  Clinical testing is  expensive, difficult to design and implement,
can take many years to complete and is uncertain  as to outcome. A failure of one  or more clinical
trials can occur at any stage of testing.  The outcome of  preclinical testing  and early clinical trials may
not be predictive of the success of later clinical  trials, and interim results  of a clinical trial do not
necessarily predict final results. The  design  of  a clinical trial can determine  whether its  results will
support approval of a product, and flaws  in the design of a clinical trial  may  not  become apparent until
the clinical trial is well advanced or completed. Moreover, preclinical and clinical data are often
susceptible to varying interpretations  and analyses,  and many companies that have believed their
product  candidates performed satisfactorily in preclinical studies and  clinical  trials have nonetheless
failed to obtain marketing approval of  their products.

We  have not completed any clinical trials of lefamulin specifically for CABP. Our  completed

Phase 2 clinical trial evaluated lefamulin in patients with acute bacterial skin and skin structure
infections, or ABSSSI. Our Phase 1 clinical trials  evaluated lefamulin in healthy subjects to obtain
tolerance data and to understand the  absorption  and distribution  of  lefamulin in the  blood and target
tissues, evaluate the metabolism and  elimination  route of  lefamulin and obtain  safety and  tolerability
data to  help predict safe and effective doses of  lefamulin  for  the treatment of  patients.  In  addition, we
are using a different intravenous, or  IV,  formulation  of  lefamulin for our Phase 3 clinical  trials for
CABP than we used in our Phase 2 clinical trial for ABSSSI. We have only evaluated this  new IV
formulation of lefamulin, a sterile saline solution  buffered by a citrate salt,  in Phase  1 clinical  trials.
Because of these and other factors, the results of  our  completed clinical  trials may not predict  success
in our Phase 3 clinical trials of lefamulin for CABP. Although we believe  that  the collective data from
prior trials and our preclinical studies provide support for concluding  that  lefamulin is well  suited for
treatment of CABP, we may fail to obtain  favorable  results in our  Phase 3 clinical trials of  lefamulin  for
CABP. If the results of our Phase 3 clinical trials are  not  favorable, including failure  to  achieve the
primary efficacy endpoints of the trials,  we  may need  to  conduct additional clinical trials at significant
cost or altogether abandon development  of lefamulin for CABP  and  potentially other indications.

If we  are required to conduct additional  clinical trials  or other testing of  lefamulin or any other

product  candidate that we develop beyond those that we contemplate, if we are unable  to  successfully
complete our clinical trials or other testing, if the results of these  trials or tests are  not  positive or  are
only modestly positive or if there are safety concerns, we may:

(cid:127) be delayed in obtaining marketing  approval for our product candidates;

(cid:127) not obtain marketing approval at all;

(cid:127) obtain approval for indications or patient populations that are not  as broad as intended or

desired;

The occurrence of any of the developments listed above  could  materially  harm our business,

If we experience any of a number of possible  unforeseen events in  connection with  our  Phase 3 clinical  trials
of lefamulin for CABP or other clinical  trials,  the potential marketing approval  or commercialization of
lefamulin or other product candidates could be delayed or prevented.

We  may experience numerous unforeseen events during,  or  as a  result of, our Phase 3 clinical
trials of lefamulin for CABP or other  clinical trials we conduct that could delay  or prevent our ability
to receive marketing approval or commercialize lefamulin  or  our other product  candidates, including:

(cid:127) clinical trials of lefamulin or our other product candidates  may  produce  negative  or inconclusive
results, and we may decide, or regulators may require us,  to  conduct additional clinical trials or
abandon product development programs;

(cid:127) the number of patients required for  clinical trials  of lefamulin for CABP, lefamulin for  other
indications or our other product candidates may be larger than we anticipate, enrollment in
these clinical trials may be slower than we  anticipate or participants  may  drop out of  these
clinical trials at a higher rate than we anticipate;

(cid:127) we may be unable to enroll a sufficient number of patients  in our Phase 3 clinical  trials of

lefamulin for CABP or other clinical  trials we  conduct to ensure adequate statistical  power  to
detect any statistically significant treatment effects;

(cid:127) our third-party contractors may fail to comply with  regulatory requirements or meet  their

contractual obligations to us in a timely manner, or at all;

(cid:127) regulators, institutional review boards  or independent ethics committees may not authorize us or
our  investigators to commence a clinical trial or conduct  a clinical  trial at a prospective  trial site
or may require that we or our investigators  suspend or  terminate clinical  research  for various
reasons, including noncompliance with  regulatory requirements or a finding that the participants
are being exposed to unacceptable health risks;

(cid:127) we may experience delays in reaching or  fail  to  reach agreement on acceptable clinical trial

contracts or clinical trial protocols with prospective trial sites;

(cid:127) we may have to suspend or terminate our Phase  3 clinical  trials of  lefamulin  for CABP or other

clinical trials of our product candidates for  various reasons, including a finding  that  the

(cid:127) our product candidates may have undesirable side  effects or other unexpected characteristics,
causing  us or our investigators, regulators, institutional review boards  or independent ethics
committees to suspend or terminate  the trials.

Our product development costs will increase if we  experience delays in enrollment  in our clinical
development program or our non-clinical development program or in  obtaining  marketing  approvals.

We  do not know whether any additional  non-clinical tests or clinical trials will be required,  or if they
will begin as planned, or if they will need  to be restructured  or  will be completed  on schedule, or at all.
Significant non-clinical development program delays, including chemistry, manufacturing and control
activities, or clinical trial delays also could  shorten any  periods during  which we may have the  exclusive
right to commercialize our product candidates  or allow our competitors to bring products to market
before we do and impair our ability to successfully commercialize our product candidates and may
harm our business and results of operations.

If we experience delays or difficulties in  the enrollment  of patients  in our clinical trials, our receipt of
necessary marketing approvals could be delayed or  prevented.

We  may not be able to initiate or continue  clinical trials  of  lefamulin or  any other product

candidate that we develop if we are unable to locate and  enroll  a  sufficient number of eligible patients
to participate in these clinical trials. In particular, we may experience  enrollment challenges at  trial
sites in the United States, where it is a common practice to place patients with potential moderate to
severe CABP on antibiotics very shortly  after examination. This  practice could prevent potential trial
patients in the United States from being enrolled in our clinical trials based on  our eligibility criteria.
In addition, some of our competitors  have ongoing clinical trials for product candidates that could be
competitive with lefamulin, and patients who would otherwise be eligible for our  clinical trials  may
instead enroll in clinical trials of our  competitors’  product candidates.

Patient enrollment is affected by other  factors including:

(cid:127) severity of the disease under investigation;

(cid:127) eligibility criteria for the clinical trial in  question;

(cid:127) perceived risks and benefits of the  product candidate under study;

(cid:127) approval of other therapies to treat  the disease under investigation;

(cid:127) efforts to facilitate timely enrollment in  clinical trials;

(cid:127) patient referral practices of physicians;

(cid:127) the time of year in which the trial is  initiated or conducted;

(cid:127) the geographic distribution of global trial  sites, given  the timing of pneumonia season globally,
and the seasonal variation in the number of  patients suffering from  pneumonia, including  a
decline in the number of patients with CABP  during the summer months;

(cid:127) the ability to monitor patients adequately  during  and  after treatment;

(cid:127) proximity and availability of clinical trial sites for  prospective patients;

(cid:127) delays in the receipt of required regulatory approvals, or the failure to  receive required

regulatory approvals, in the jurisdictions  in which clinical trials are expected to be conducted;
and

(cid:127) delays in the receipt of approvals, or the  failure to receive approvals, from  the relevant

institutional review board or ethics committee at  clinical trial sites.

For example, in each of our Phase 3 clinical  trials of lefamulin, patients who  have previously taken
no more than one dose of a short acting,  potentially effective antibiotic for the treatment of the current
CABP episode within 24 hours of receiving the first  dose of study medication will be allowed to
participate in the trial but will comprise only up to 25% of the  total intent to treat  populations.
Depending upon a region’s or a clinical  trial site’s standard  of care for the administration  of antibiotics,
this  could affect our ability to enroll  patients  in these clinical  trials in  a  timely fashion. Also, enrollment

for our  Phase 3 clinical trials may be  negatively impacted by delays  in opening  clinical trial sites or the
duration and/or severity of the influenza  season.  Moreover,  our estimates regarding  patient  enrollment
for our  Phase 3 clinical trials of lefamulin depend on increasing enrollment rates as each  such trial
progresses, making it more difficult to  precisely estimate the time of completion of such  trials during its
earlier stages. Enrollment delays in our clinical  trials may result in increased development  costs for our
product  candidates, which would cause the  value  of  the company  to  decline and limit our ability to
obtain additional financing. Our inability  to  enroll a sufficient number  of  patients in our Phase 3
clinical trials of lefamulin for CABP  or  any  of  our other clinical trials would  result in significant delays
or may require us to abandon one or more clinical trials  altogether.

If serious  adverse or undesirable side effects are identified during  the development of  lefamulin or any other
product candidate that we develop, we may  need  to abandon or limit  our development  of that product
candidate.

All of our product candidates are in clinical  or preclinical development and  their  risk of failure is
high. It is impossible to predict when or  if any of our product  candidates will prove effective or safe  in
humans or will receive marketing approval. If  our  product candidates  are associated  with undesirable
side effects or have characteristics that  are  unexpected, we may need to abandon their  development or
limit development to certain uses or subpopulations  in which the undesirable side  effects or other
characteristics are less prevalent, less  severe or  more acceptable from a  risk-benefit perspective. Many
compounds that initially showed promise  in  clinical  or earlier  stage testing have  later been  found to
cause  side effects or other safety issues that prevented further development of the  compound.

Lefamulin was well tolerated in our Phase 2  clinical  trial  for ABSSSI. No  patient  in the trial
suffered any serious adverse events that were  found to be related  to  lefamulin, and  no patient in  the
trial died. Some patients experienced  adverse events that  were assessed by  the investigator as possibly
or probably related to study medication. The majority  of  their symptoms were mild  in severity. Four
patients discontinued study medication following a  drug-related event, three  of whom  were in a
lefamulin treatment group: one patient experienced  events of hyperhidrosis, vomiting and headache;
one patient experienced infusion site pain; and one patient experienced dyspnea.

Because the potential for mild effect  on electrocardiogram,  or ECG, measurements was observed

in preclinical studies, we have continued  to assess this potential in all human clinical  trials we  have
conducted. In the Phase 2 clinical trial,  no change  in ECG measurements  was  considered to be of
clinical significance, and no drug-related  cardiovascular adverse event  was reported. Both lefamulin and
vancomycin treatment were associated  with a small  increase in  the QT interval.  The QT interval  is a
measure of the heart’s electrical cycle, with a  lengthened QT interval  representing  a marker for
potential ventricular arrhythmia. We are continuing to evaluate the effect of lefamulin on the QT
interval in our Phase 3 clinical trials  of  lefamulin  for  CABP.

There were no systemic adverse events of clinical concern and no drug-related serious  adverse

events observed in any of our completed  Phase 1  clinical trials  of  lefamulin. In these trials, the most
commonly observed adverse effects with  oral administration of lefamulin were related  to  the
gastrointestinal tract, including nausea  and  abdominal discomfort,  while the  most commonly observed
adverse effects related to IV administration were  related to  irritation at the infusion site. In addition,
lefamulin produced a transient, predictable and reproducible  prolongation of  the QT interval  based on
the maximum concentration of the drug in the blood plasma.  At  therapeutic doses,  we expect that the
drug will not  produce large effects on  the QT interval that would be of  clinical relevance.  We  did not
observe any drug-related cardiac adverse  events, such as  increase in  ectopic ventricular activity or  other
cardiac arrhythmia, or clinically relevant ECG findings during  the conduct  of any  of  our  completed
Phase 1 clinical trials. None of the ECG  stopping criteria defined in  the trial protocols was reached in
any clinical trial. However, if we observe  clinically relevant effects  on the QT interval in our Phase 3

clinical trials of lefamulin for CABP  or  in  any other clinical trial  of  lefamulin, our  ability to successfully
develop lefamulin for CABP or any other  indication may  be significantly delayed or prevented.

If we  elect or are forced to suspend or terminate any clinical trial of lefamulin or any other
product  candidates that we are developing, the commercial prospects  of lefamulin or such other
product  candidates will be harmed and our  ability  to  generate  product revenues, if at all, from
lefamulin or any of these other product candidates will be delayed or eliminated.  Any  of  these
occurrences could materially harm our  business, financial condition, results of operations and  prospects.

Even if lefamulin or any other product  candidate  receives marketing  approval, it may fail to achieve  the
degree of market acceptance by physicians, patients, third-party payors and others in the  medical community
necessary for commercial success and the  market opportunity for lefamulin may  be  smaller  than we  estimate.

If lefamulin or any of our other product candidates receive marketing approval,  they may
nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors  and
others in the  medical community. For  example,  current treatments for pneumonia,  including generic
options, are well established in the medical community, and  doctors may  continue to rely  on these
treatments without lefamulin. In addition,  our efforts to effectively communicate  lefamulin’s
differentiating characteristics and key attributes to clinicians  and hospital pharmacies with the goal of
establishing favorable formulary status  for lefamulin may  fail or  may be less  successful than we  expect.
If lefamulin does not achieve an adequate level of acceptance, we  may not generate significant product
revenues or any profits from operations. The degree of market acceptance of our product candidates, if
approved for commercial sale, will depend on a number of factors, including:

(cid:127) the efficacy and potential advantages compared to alternative treatments;

(cid:127) lefamulin’s ability to limit the development  of bacterial resistance in the  pathogens  it targets;

(cid:127) the prevalence and severity of any  side effects;

(cid:127) the ability to offer our product candidates for sale at competitive prices, including  in comparison

to generic competition;

(cid:127) convenience and ease of administration compared to alternative treatments;

(cid:127) the willingness of the target patient population to try  new  therapies, physicians to prescribe these

therapies and hospitals to approve the cost and use by their  physicians of these  therapies;

(cid:127) the strength of marketing and distribution  support;

(cid:127) the availability of third-party coverage and adequate  reimbursement; and

(cid:127) the timing of any marketing approval in relation to other product approvals.

Although we believe that the mechanism of action for pleuromutilin antibiotics may  result in a  low

propensity for development of bacterial  resistance  to  lefamulin or our other pleuromutilin product
candidates, bacteria might nevertheless  develop  resistance to lefamulin  or our other pleuromutilin
product  candidates more rapidly or to  a greater degree than  we  anticipate.  If bacteria develop such
resistance or if lefamulin is not effective against drug-resistant  bacteria,  the efficacy of these product
candidates would decline, which would negatively affect  our potential to generate revenues from these
product  candidates.

Our ability to negotiate, secure and maintain third-party coverage and  reimbursement may be
affected by political, economic and regulatory developments in  the United States,  the European  Union
and other jurisdictions. Governments continue to impose cost containment  measures, and  third-party
payors are increasingly challenging prices  charged for medicines and examining their cost  effectiveness,
in addition to their safety and efficacy. If  the level  of  reimbursement is below our expectations,  our

revenue and gross margins would be adversely affected. Obtaining formulary approval from  third-party
payors can be an expensive and time-consuming process.  We cannot be certain if and when  we will
obtain formulary approval to allow us  to  sell  lefamulin or any future product candidates into our  target
markets. Even if we do obtain formulary approval, third-party payors, such as government or  private
health care insurers, carefully review  and increasingly question the  coverage of, and  challenge the prices
charged for, drugs. These and other  similar developments  could significantly  limit  the degree of market
acceptance of lefamulin or any of our other product candidates  that receive marketing approval.

If we are unable to establish sales, marketing  and  distribution  capabilities or enter into sales, marketing and
distribution agreements with third parties, we may not  be successful in commercializing lefamulin or any
other product candidate if and when they  are approved.

We  do not have a sales, marketing or distribution infrastructure, and as  a  company we  have no
experience in the sale, marketing or distribution  of pharmaceutical products. To achieve commercial
success for any approved product, we must  either develop a sales, marketing and distribution
organization or outsource these functions  to third parties.  If lefamulin receives marketing  approval, we
plan  to commercialize it in the United States with our own targeted hospital sales and marketing
organization that we plan to establish. In  addition,  we expect to utilize a variety of  types of
collaboration, distribution and other marketing arrangements  with one  or more third parties to
commercialize lefamulin in markets outside the  United States.

There are risks involved with establishing our  own sales, marketing and  distribution capabilities
and entering into arrangements with third parties to perform these services. For example,  recruiting
and training a sales force is expensive and time consuming and could  delay any product  launch. If the
commercial launch of a product candidate  for which we recruit a  sales  force and establish marketing
and distribution capabilities is delayed or does  not  occur for any  reason,  we would  have prematurely or
unnecessarily incurred these commercialization expenses. This may  be  costly,  and our investment would
be lost if we cannot retain or reposition our  sales  and marketing personnel.

Factors that may inhibit our efforts to  commercialize our products on our own include:

(cid:127) our inability to recruit, train and retain adequate numbers  of effective sales and marketing

personnel;

(cid:127) the inability of sales personnel to obtain access to or persuade adequate numbers of physicians

to prescribe any future products;

(cid:127) the lack of complementary products to be offered  by sales personnel, which may  put  our sales
representatives at a competitive disadvantage relative to sales representatives from  companies
with more extensive product lines; and

(cid:127) unforeseen costs and expenses associated with  creating an independent sales, marketing  and

distribution organization.

If we  enter into arrangements with third parties  to  perform sales, marketing and distribution
services, our product revenues or the  profitability of these product revenues  to  us are likely to be lower
than if we were to market, sell and distribute ourselves any products that we  develop.  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 them  may fail  to  devote  the necessary resources and
attention to sell and market our products effectively.  If we  do not establish sales, marketing and
distribution capabilities successfully, either on our own or in collaboration with third parties, we will  not
be successful in commercializing our product candidates.

We face substantial competition, which  may  result  in  others discovering, developing or commercializing
products  before or more successfully than  we do.

The development and commercialization of  new drug products is highly competitive. We face
competition with respect to lefamulin  and  any  other products we may seek  to  develop  or commercialize
in the future from major pharmaceutical companies, specialty pharmaceutical companies and
biotechnology companies worldwide.  Potential competitors  also  include academic  institutions,
government agencies and other public and private  research  organizations that conduct research, seek
patent protection and establish collaborative arrangements for  research, development, manufacturing
and commercialization.

There are a variety of available therapies marketed  for the  treatment of CABP. Currently the
treatment of CABP is dominated by generic products. For hospitalized patients,  combination  therapy is
frequently used. Many currently approved drugs are  well-established therapies  and are widely accepted
by physicians, patients and third-party  payors. We also are aware  of  various drugs  under development
for the treatment of CABP, including solithromycin, (New  Drug  Application, or NDA, filed  by
Cempra Inc. and a complete response letter  issued by  the FDA in  December 2016), omadacycline
(under Phase 3 clinical development  by Paratek Pharmaceuticals Inc.), delafloxacin (under Phase 3
clinical development by Melinta Therapeutics Inc.) and oral nafithromycin (under  Phase 2  clinical
development by Wockhardt Ltd.).

Our commercial opportunity could be reduced  or eliminated  if our competitors  develop  and
commercialize products that are safer,  more  effective, have fewer or less severe side effects,  are
approved for broader indications or patient populations, are more  convenient or are  less  expensive  than
any products  that we may develop. Our  competitors may also  obtain  marketing  approvals 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 because in  some cases  insurers  or  other third-party  payors seek to encourage
the use of generic products. This may have the effect  of making branded products  less  attractive, from
a cost perspective, to buyers. We expect that if lefamulin is  approved for  CABP, it  will be priced at a
significant premium over competitive  generic products. This  may  make it difficult for us to replace
existing therapies with lefamulin. The key competitive factors affecting the  success of our product
candidates are likely to be their efficacy, safety,  convenience, price  and  the  availability of coverage and
reimbursement from government and other third-party  payors.

Many of our competitors may have significantly  greater  financial resources and  expertise in
research and development, manufacturing,  preclinical testing, conducting  clinical trials,  obtaining
approvals from regulatory authorities 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 and other early  stage
companies may also prove to be significant competitors,  particularly through collaborative arrangements
with large and established companies.  These  third  parties compete with us in recruiting and  retaining
qualified scientific and management personnel,  establishing clinical trial sites and patient registration
for clinical trials, as well as in acquiring  technologies complementary to or  necessary  for our programs.

Even if we are able to commercialize lefamulin or any other product candidate  that we develop, the  product
may become subject to unfavorable pricing regulations,  third-party  reimbursement practices  or healthcare
reform initiatives, which would harm our business.

The regulations that govern marketing approvals,  pricing, coverage and  reimbursement for  new
drug products vary widely from country to country. Current and future legislation may significantly
change the approval requirements in  ways that could involve additional costs and  cause delays in
obtaining approvals. 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  might obtain
marketing approval for a product in a  particular country, but  then be subject to price regulations that
delay our commercial launch of the product, possibly for lengthy time periods, and negatively  impact
the revenues we are able to generate from  the sale of the product  in that country.  Adverse  pricing
limitations may hinder our ability to  recoup our investment in  one or more product candidates, even if
our  product candidates obtain marketing  approval.

Our ability to commercialize lefamulin or any other product candidate  successfully also will  depend

in part on the extent to which coverage and  adequate reimbursement  for  these products and related
treatments will be available from government health administration authorities,  private health insurers
and other organizations. Government authorities and other third-party payors, such  as private  health
insurers and health maintenance organizations, decide which medications  they will pay  for and establish
reimbursement levels. A major trend  in  the healthcare industries  in the European Union and the
United States and elsewhere is cost containment.  Government  authorities and  other  third-party payors
have attempted to control costs by limiting  coverage and the amount of reimbursement  for particular
medications. Increasingly, third-party  payors 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 lefamulin or any other
product  that we commercialize and, if  coverage and reimbursement are available,  the level  of
reimbursement. Reimbursement may  impact  the demand for, or the  price of, any product candidate for
which  we obtain marketing approval. Obtaining and maintaining adequate reimbursement for lefamulin
may be particularly difficult because of the number of generic  drugs, which  are typically available at
lower prices, that are available to treat CABP. In addition, third-party  payors are likely to impose strict
requirements for reimbursement of a higher  priced  drug,  such as  lefamulin. If reimbursement  is not
available or is available only to limited levels, we may not be able  to  successfully commercialize
lefamulin or other product candidates  for which  we obtain marketing approval.

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
applicable regulatory authority. Moreover, eligibility  for coverage and  reimbursement does  not  imply
that any drug will be paid for in all cases  or  at a  rate that covers our costs, including  research,
development, manufacture, sale and distribution. Interim reimbursement levels for new drugs,  if
applicable, may also not be sufficient  to  cover our 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 payors 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 United States. In the United  States, third-party payors  often rely upon Medicare coverage
policy and payment limitations in setting  their own reimbursement policies. In the European Union,
reference pricing systems and other measures may lead to cost containment and reduced prices.  Our
inability to promptly obtain coverage and adequate  reimbursement rates from both government-funded
and private payors for any approved products that  we 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.

Product liability lawsuits against us could  divert our  resources, cause us  to  incur  substantial  liabilities and  to
limit commercialization of any products that  we may develop  or in-license.

We  face an inherent risk of product liability exposure related to the testing  of  lefamulin and  any
other product candidate that we develop in human clinical trials and will face  an even greater  risk if  we
commercially sell any products that we  may develop or  in-license. If we cannot successfully defend
ourselves  against claims that our product candidates or products  caused injuries, we will incur
substantial liabilities. Regardless of merit  or eventual outcome, liability claims may  result in:

(cid:127) reduced resources of our management to pursue  our  business  strategy;

(cid:127) decreased demand for any product candidates or products that  we may develop;

(cid:127) injury to our reputation and significant negative media  attention;

(cid:127) withdrawal of clinical trial participants;

(cid:127) significant costs to defend the related  litigation;

(cid:127) substantial monetary awards to trial participants or patients;

(cid:127) loss of revenue; and

(cid:127) the inability to commercialize any  products that we  may develop.

We  maintain product liability insurance that covers bodily  injury to patients participating in our
clinical trials up to a $10.0 million annual  aggregate limit and subject to a per event  deductible. This
amount of insurance may not be adequate to cover all liabilities that  we may incur. We will need to
increase our insurance coverage when and if we begin commercializing lefamulin or any other product
candidate that receives marketing approval. Insurance coverage is increasingly expensive. We may not
be able to maintain insurance coverage at  a reasonable cost or  in an amount adequate to satisfy  any
liability that may arise.

Risks Related to Our Dependence on Third  Parties

Use of third parties to manufacture our  product candidates may  increase the  risk  that we will not have
sufficient quantities of our product candidates or products or  such quantities  at an acceptable cost, which
could delay, prevent or impair our development or  commercialization efforts.

We  do not own or operate manufacturing facilities for the production of lefamulin that could be

used in product candidate development,  including clinical  trial supply, or  for commercial  supply, or for
the supply of any other compound that  we are developing or evaluating in our  research  program. We
have limited personnel with experience in  drug manufacturing and lack  the resources and the
capabilities to manufacture any of our  product  candidates on  a clinical  or commercial scale.  We
currently rely on third parties for supply  of  lefamulin, and  our  strategy is  to outsource all
manufacturing of our product candidates and products to third parties.

We  do not currently have any agreements with third-party  manufacturers  for  the long-term
commercial supply of any of our product candidates. We obtained the pleuromutilin starting material
for the clinical trial supply of lefamulin from  a single third-party manufacturer, Sandoz  GmbH, or
Sandoz, a division of Novartis AG, or Novartis. We have identified an  alternative  supplier that we
believe will be able to provide pleuromutilin starting material for the commercial supply of lefamulin.
Another third-party manufacturer synthesizes  lefamulin from the  pleuromutilin  starting material and
provides our supply of the active pharmaceutical  ingredient.  We engage separate manufacturers to
provide fill and finish services for the  finished  product that  we are  using  in our clinical  trials of
lefamulin. We may be unable to conclude agreements  for commercial  supply with third-party
manufacturers, or may be unable to  do  so on acceptable terms.

Even if we are able to establish and maintain arrangements with third-party manufacturers,

reliance on third-party manufacturers entails risks, including:

(cid:127) reliance on the third party for regulatory compliance and quality  assurance;

(cid:127) the possible breach of the manufacturing agreement by the  third  party;

(cid:127) the possible misappropriation of our proprietary information, including  our  trade secrets and

know-how; and

(cid:127) the possible termination or nonrenewal of the  agreement by  the third party at a time that is

costly or inconvenient for us.

Third-party manufacturers may not be able to comply with current  good manufacturing  practice, or

cGMP, regulations or similar regulatory  requirements outside  the United States. Our  failure, or the
failure of our third-party manufacturers, to comply with  applicable  regulations could result in sanctions
being imposed on us, including fines, injunctions, civil  penalties,  delays, suspension or withdrawal of
approvals, license revocation, seizures or recalls of product  candidates or  products, operating
restrictions and criminal prosecutions,  any  of which  could  significantly and adversely  affect supplies of
our  product candidates.

Our product candidates and any products  that we may  develop may compete with other  product

candidates and products for access to  manufacturing facilities. There are a limited  number of
manufacturers that operate under cGMP  regulations  and  that might be capable of manufacturing for
us.

If the third parties that we engage to  supply any  materials or manufacture  product for our

non-clinical testing and clinical trials  should cease to continue to do so  for  any reason, we  likely would
experience delays in advancing these  trials  while we  identify and qualify replacement suppliers and we
may be unable to obtain replacement  supplies on terms  that  are  favorable to us. For example, there  are
only a limited number of known manufacturers that  produce the pleuromutilin  starting material used in
the synthesis of lefamulin. In early 2015, Novartis  announced the  sale of its animal health division,
including its veterinary products, to a third party. As a result, we have identified an alternative supplier
that currently manufactures pleuromutilin  starting material for veterinary  products, that we believe will
be able to provide pleuromutilin starting  material  for  the commercial scale manufacture of  lefamulin.
In addition, if we are not able to obtain adequate supplies of our  product candidates  or the drug
substances used to manufacture them, it  will be more difficult for us  to  develop our product candidates
and compete effectively.

Our current and anticipated future dependence upon others for the manufacture  of our  product
candidates may adversely affect our future profit  margins and our ability to develop product  candidates
and commercialize any products that  receive  marketing approval on a timely and competitive basis.

We rely on third parties to conduct our clinical  trials and those third parties  may not perform satisfactorily,
including failing to meet deadlines for the completion of such trials.

We  do not independently conduct clinical trials for our product  candidates. We rely on third
parties, such as contract research organizations, clinical data management organizations, medical
institutions and clinical investigators,  to  perform this function. We expect  to continue to rely on such
third parties in conducting our clinical  trials of  lefamulin,  and expect to rely on  these  third parties to
conduct clinical trials of any other product candidate  that we  develop. Any  of  these  third parties may
terminate their engagements with us  at any time. If  we need to enter into alternative  arrangements, it
would delay our product development activities.

Our reliance on these third parties for clinical development activities reduces  our control  over
these activities but does not relieve us of  our  responsibilities. For example, we remain responsible for

ensuring that each of our clinical trials is conducted  in accordance with the general investigational plan
and protocols for the trial. Moreover,  the FDA requires us  to  comply  with standards,  commonly
referred to as Good Clinical Practices, or  GCP, for  conducting,  recording and  reporting the results of
clinical trials to assure that data and  reported results are credible and accurate and  that  the rights,
integrity and confidentiality of trial participants are  protected. We also are required  to  register  ongoing
clinical trials and post the results of completed  clinical  trials on a U.S. government-sponsored  database,
ClinicalTrials.gov, within certain timeframes. Failure to do so can  result in  fines, adverse publicity and
civil and criminal sanctions. Similar GCP  and transparency  requirements apply in  the European  Union.
Failure to comply with such requirements,  including  with respect to clinical trials  conducted outside the
European Union, can also lead regulatory  authorities to refuse to take into  account clinical  trial  data
submitted as part of a marketing authorization application, or MAA.

Furthermore, third parties that we rely on for our  clinical development activities  may also have

relationships with other entities, some  of  which may be our competitors. If these third parties  do  not
successfully carry out their contractual duties, meet expected deadlines or conduct our clinical trials in
accordance with regulatory requirements or our stated protocols, we will not be able  to  obtain,  or may
be delayed in obtaining, marketing approvals for our product candidates and will  not  be  able to, or  may
be delayed in our efforts to, successfully  commercialize our product candidates. Our product
development costs will increase if we  experience  delays in  testing or obtaining  marketing  approvals.

We  also rely on other third parties to store and distribute drug supplies  for our clinical trials. Any

performance failure on the part of our distributors could delay  clinical development  or marketing
approval of our product candidates or  commercialization of our products, producing additional  losses
and depriving us of potential product revenue.

We may  enter into collaborations with third parties for the  development or  commercialization of lefamulin and
our other product candidates. If those collaborations are  not successful,  we may  not  be  able to  capitalize on
the market potential of these product candidates.

If lefamulin receives marketing approval, we plan  to  commercialize it  in the United States with  our
own targeted hospital sales and marketing organization.  Outside the United States, we expect  to  utilize
a variety of types of collaboration, distribution and other marketing arrangements with one  or more
third parties to commercialize lefamulin. We also may seek third-party collaborators  for development
and commercialization of other product candidates or for  lefamulin  for  indications other  than CABP.
Our likely collaborators for any sales,  marketing,  distribution, development, licensing or  broader
collaboration arrangements include large and  mid-size pharmaceutical  companies, regional and  national
pharmaceutical companies and biotechnology  companies. We are not  currently  party to any  such
arrangement. However, if we do enter  into any such arrangements with  any third parties  in the future,
we will likely have limited control over the amount and timing of  resources  that  our collaborators
dedicate to the development or commercialization of our product candidates. Our ability to generate
revenues from these arrangements will  depend  on our collaborators’ abilities and  efforts to successfully
perform the functions assigned to them  in these arrangements.

Collaborations involving our product  candidates  would pose  numerous risks to us, including the

following:

(cid:127) collaborators have significant discretion in determining  the efforts and resources that they will

apply  to these collaborations and may not perform their obligations as expected;

(cid:127) collaborators may deemphasize or  not pursue development  and commercialization  of our

product candidates or may elect not to continue or renew development or  commercialization
programs based on clinical trial results, changes  in the collaborators’ strategic focus, product and
product candidate priorities, available funding, or external factors such  as an acquisition that
diverts resources or creates competing  priorities;

(cid:127) collaborators may delay clinical trials, provide  insufficient funding for a clinical trial program,
stop a clinical trial or abandon a product  candidate, repeat or conduct new clinical  trials or
require a new formulation of a product candidate  for clinical testing;

(cid:127) collaborators could independently develop, or  develop  with third parties,  products that compete
directly or indirectly with our products or product candidates  if the collaborators believe that
competitive products are more likely to be successfully developed  or can  be  commercialized
under terms that are more economically attractive than  ours;

(cid:127) a collaborator with marketing and distribution rights to one or more products may  not  commit

sufficient resources to the marketing and distribution  of such product  or products;

(cid:127) collaborators may not properly maintain  or defend our intellectual property  rights or may  use

our  proprietary information in such a  way as  to  invite litigation  that could  jeopardize or
invalidate our intellectual property or proprietary information or expose  us to potential
litigation;

(cid:127) collaborators may infringe the intellectual property rights of third  parties, which  may expose us

to litigation and potential liability;

(cid:127) disputes may arise between the collaborator  and  us  as to the ownership of  intellectual property

arising during the collaboration;

(cid:127) we may grant exclusive rights to our collaborators, which would prevent us from collaborating

with others;

(cid:127) disputes may arise between the collaborators and us  that result in  the delay  or termination  of
the research, development or commercialization of our products or product candidates or  that
result in costly litigation or arbitration  that  diverts  management attention  and resources; and

(cid:127) collaborations may be terminated and, if  terminated, may  result  in a need  for additional capital

to pursue further development or commercialization of the applicable product candidates.

For example, in 2012, we entered into  a stock purchase agreement  with Forest pursuant to which

Forest reimbursed us for certain external  research and  development costs  and provided us with  a
$25.0 million loan in exchange for an exclusive right to acquire 100% of our outstanding  shares for a
one-year period. However, in 2013, Forest decided not to exercise its right to acquire us and  terminated
the stock purchase agreement. In connection with this termination, we repurchased  the $25.0 million
loan for A1.00. We no longer have a commercial relationship with Forest,  and  no rights  or obligations
remain outstanding under the stock purchase agreement.

Collaboration agreements may not lead  to  development or  commercialization of product
candidates in the most efficient manner  or at  all.  If a  collaborator of  ours  were to be involved in a
business combination, the continued pursuit and emphasis on  our product development or
commercialization program could be delayed, diminished or terminated.

If we are not able to establish collaborations, we may  have to alter our development and commercialization
plans.

The potential commercialization of lefamulin and the development and potential

commercialization of other product candidates  will  require substantial additional cash to fund expenses.
For some of our product candidates,  we  may decide to collaborate  with pharmaceutical and
biotechnology companies for the development and potential  commercialization  of those product
candidates. For example, we intend to seek  to  commercialize lefamulin through a  variety of  types of
collaboration arrangements outside the United States.

We  face significant competition in seeking  appropriate collaborators.  Whether we reach  a definitive

agreement for a collaboration will depend, among other things, upon  our  assessment of the
collaborator’s resources and expertise,  the terms  and  conditions of the proposed collaboration and  the
proposed collaborator’s evaluation of  a  number of factors. Those factors may include the  design or
results of clinical trials, the likelihood  of  approval  by  the FDA or  similar regulatory  authorities  outside
the United States, the potential market  for the subject  product candidate, the  costs and complexities  of
manufacturing and delivering such product candidate to patients, the potential of competing products,
the existence of uncertainty with respect to our  ownership  of technology,  which can exist if there is  a
challenge to such ownership without  regard to the merits of the challenge, and  industry  and market
conditions generally. The collaborator may also consider  alternative  product candidates  or technologies
for similar indications that may be available to collaborate  on and whether such a collaboration could
be more attractive than the one with  us for our product  candidate.  We may also be restricted  under
future license agreements from entering into agreements  on certain  terms with  potential collaborators.
Collaborations are complex and time-consuming to negotiate and document. In addition, there have
been a significant number of recent business combinations among large  pharmaceutical companies that
have resulted in a reduced number of  potential future collaborators.

If we  are unable to reach agreements with suitable collaborators  on a  timely basis, on  acceptable

terms, or at all, we may have to curtail the development of  a  product candidate,  reduce or delay its
development program or one or more of  our other development  programs,  delay its potential
commercialization or reduce the scope  of any sales or marketing activities, or increase  our  expenditures
and undertake development or commercialization  activities at our  own expense. If we elect to fund and
undertake development or commercialization activities on our own, we may need to obtain additional
expertise and additional capital, which may not  be  available to us  on  acceptable terms or at  all.  If we
fail to enter into collaborations and do not have  sufficient funds or expertise to undertake the
necessary development and commercialization activities,  we may not  be  able to further develop our
product  candidates or bring them to  market and  generate  product revenue.

Risks Related to Our Intellectual Property

If we are unable to obtain and maintain  patent protection  for our technology and products, or if the  scope  of
the patent protection is not sufficiently broad, our competitors could develop and  commercialize technology
and products similar or identical to ours, and our ability to successfully commercialize our technology and
products  may be adversely affected.

Our success depends in large part on our  ability to obtain and maintain patent protection  in the

United States and other countries with  respect  to  our proprietary technology and  products. We seek to
protect our proprietary position by filing patent applications in the United States, Europe and  in
certain additional foreign jurisdictions  related to our novel  technologies and product candidates that
are important to our business. This process  is expensive and  time-consuming, and we may  not  be  able
to file and prosecute all necessary or  desirable  patent applications  at  a  reasonable cost  or in a timely
manner. It is  also possible that we will fail to identify patentable aspects  of  our research and
development output before it is too late  to  obtain patent protection. Moreover, if we  license technology
or product candidates from third parties in the future, these  license agreements may not permit us to
control the preparation, filing and prosecution of  patent  applications, or to maintain or enforce the
patents, covering this intellectual property. These agreements could also  give our licensors the right to
enforce the licensed patents without  our  involvement,  or to decide not  to  enforce the patents at all.
Therefore, in these circumstances, these patents  and applications  may  not  be  prosecuted and enforced
in a manner consistent with the best interests of our business.

The patent position of biotechnology and pharmaceutical  companies  generally is  highly uncertain,

involves complex legal and factual questions and has in recent years been  the subject of much litigation.
As a result, the issuance, scope, validity,  enforceability and commercial  value of our patent rights  are

highly uncertain. Our pending and future  patent applications  may  not  result in patents  being  issued
which  protect our technology or products, in  whole or  in part, or which effectively prevent others from
commercializing competitive technologies and products.  Changes in  either the patent laws or
interpretation of the patent laws in the United States and other countries may  diminish the value of
our  patents or narrow the scope of our  patent protection.

The laws of foreign countries may not protect our rights to  the same extent  as the laws of the
United States. For example, European  patent  law  restricts the patentability of methods of treatment  of
the human body more than U.S. law  does. We also  may not pursue or  obtain  patent  protection in  all
major markets or may not obtain protection  that  enables us to prevent  the entry of third parties  onto
the market. Assuming the other requirements for  patentability  are met, currently,  the first to file a
patent application is generally entitled to the patent. However, prior  to  March  16, 2013, in the United
States, the first to invent was entitled  to  the patent. Publications of discoveries  in the scientific
literature often lag behind the actual discoveries,  and  patent  applications  in the United States and
other jurisdictions are typically not published until  18 months after filing, or in some cases  not  at all.
Therefore, we cannot know with certainty  whether we  were  the first  to  make  the inventions claimed in
our  U.S. patents or pending U.S. patent  applications, or  that we were the first to file  for patent
protection of such inventions.

Moreover, we may be subject to a third party pre-issuance  submission  of prior art to the  U.S.
Patent and Trademark Office, or USPTO, or become  involved  in opposition, derivation, reexamination,
inter partes review, post grant review, interference proceedings  or other patent office  proceedings or
litigation, in the United States or elsewhere, challenging our  patent rights or the  patent  rights of others.
An adverse determination in any such submission, proceeding  or  litigation could reduce  the scope of,
or invalidate, our patent rights, allow third parties  to  commercialize our technology  or products  and
compete directly with us, without payment to us, or result in our inability to manufacture  or
commercialize products without infringing third-party  patent  rights. In addition, if the breadth  or
strength of protection provided by our  patents and patent applications is threatened,  it could dissuade
companies from collaborating with us  to  license,  develop  or commercialize current or future  product
candidates.

Even if our patent applications issue as patents, they may not issue in a form that will  provide us
with any meaningful protection, prevent competitors  from competing  with us or  otherwise provide us
with any competitive advantage. Our competitors may be able to circumvent our owned  or licensed
patents by developing similar or alternative technologies or products in a  non-infringing manner. In
addition, other companies may attempt  to  circumvent  any  regulatory data protection or market
exclusivity that we obtain under applicable legislation,  which may  require  us to allocate significant
resources to preventing such circumvention. Legal and regulatory  developments in the European Union
and elsewhere may also result in clinical trial data submitted as part of an MAA becoming publicly
available. Such developments could enable other companies to circumvent our intellectual property
rights and use our clinical trial data to obtain  marketing  authorizations in  the European  Union and in
other jurisdictions. Such developments may  also require us to allocate significant resources  to  prevent
other companies from circumventing  or violating  our intellectual  property  rights. Our  attempts  to
prevent third parties from circumventing  our intellectual property and  other rights  may ultimately  be
unsuccessful. We may also fail to take  the required actions or pay the necessary fees to maintain our
patents.

The issuance of a patent is not conclusive as to its inventorship,  scope,  validity or  enforceability,
and our owned and licensed patents  may be challenged in the  courts or patent  offices in  the United
States and abroad. Such challenges may  result in  loss of exclusivity  or freedom to operate or in patent
claims being narrowed, invalidated or  held unenforceable, in whole or in  part, which could limit our
ability to stop others from using or commercializing similar or identical technology and products, or
limit the duration of the patent protection of our technology  and products. Given the amount of  time

required for the development, testing  and  regulatory review of new  product candidates, patents
protecting such candidates might expire before or shortly after such candidates  are commercialized. As
a result, our patent portfolio may not  provide us with  sufficient rights to exclude  others from
commercializing products similar or identical to ours.

We may  become involved in lawsuits to protect  or enforce our patents or  other  intellectual property,  which
could be expensive,  time consuming and unsuccessful.

Competitors may infringe our patents, trademarks,  copyrights or other intellectual  property. To

counter such infringement or unauthorized use, we may be required to file claims, which  can be
expensive and time consuming. Any claims  we assert against perceived  infringers could provoke these
parties to assert counterclaims against us  alleging that we infringe their intellectual property. In
addition, in a patent infringement proceeding, a court may decide that a  patent  of  ours  is invalid or
unenforceable, in whole or in part, construe the patent’s claims narrowly  or  may refuse to stop  the
other party from using the technology at  issue on the  grounds that our patents do not cover the
technology in question.

Third parties may initiate legal proceedings  alleging  that we are infringing  their intellectual property rights,
the outcome of which would be uncertain  and could have a  material adverse  effect on  the success  of our
business.

Our commercial success depends upon  our  ability and the  ability of our collaborators to develop,

manufacture, market and sell our product candidates and use  our proprietary technologies without
infringing the intellectual property and  other proprietary rights of third parties. There is considerable
intellectual property litigation in the biotechnology and pharmaceutical  industries, and we  may become
party to, or threatened with, future adversarial proceedings  or litigation regarding intellectual  property
rights with respect to our products and  technology, including interference, derivation, inter partes review
or post-grant review proceedings before  the  USPTO. The risks of being  involved in such litigation and
proceedings may increase as our product candidates approach commercialization, and as we gain
greater visibility as a public company.  Third parties may assert infringement claims against us based on
existing or future intellectual property rights. We may not be aware of all  such intellectual property
rights potentially relating to our product candidates. Any freedom-to-operate  search  or analysis
previously conducted may not have uncovered all relevant patents and patent applications, and there
may be pending or future patent applications  that, if issued,  would block us from commercializing
lefamulin. Thus, we do not know with  certainty  whether lefamulin, any other product candidate, or our
commercialization thereof, does not and will not infringe any third  party’s intellectual  property.

If we  are found to infringe a third party’s intellectual property rights, or to avoid  or settle

litigation, we could be required to obtain a license to continue developing and  marketing  our products
and technology. However, we may not  be  able  to  obtain  any required license on  commercially
reasonable terms or at all. Even if we were able to obtain a license, it could be non-exclusive, thereby
giving our competitors access to the same technologies  licensed to us, and could require us to make
substantial payments. We could be forced, including by court  order, to cease commercializing the
infringing technology or product. In addition,  we could be found liable for monetary damages, including
treble damages and attorneys’ fees if we are found to have willfully infringed a  patent  or other
intellectual property right. A finding  of  infringement  could prevent us from commercializing our
product  candidates or force us to cease  some of  our business operations, which could materially harm
our  business. Claims that we have misappropriated  the confidential information  or trade secrets of third
parties could have a similar negative  impact on our  business.

We may  be subject to claims by third parties  asserting that we or our employees have misappropriated  their
intellectual property, or claiming ownership of what  we regard as our own  intellectual property.

Many of our employees were previously employed at  universities or other biotechnology  or
pharmaceutical companies, including  our competitors  or potential competitors. Although we try to
ensure that our employees do not use the proprietary  information  or know-how of others in  their work
for us, we may be subject to claims that we or these employees  have used or disclosed  intellectual
property, including trade secrets or other proprietary information, of any such  employee’s former
employer. Litigation may be necessary to defend  against these claims.

In addition, while we typically require our employees and contractors who may  be  involved in  the
development of intellectual property to execute agreements assigning such  intellectual property  to  us,
we may be unsuccessful in executing such an agreement with each party who  in fact  develops
intellectual property that we regard as  our own. Our business was founded as a spin-off from Sandoz.
Although all patent applications are  fully  owned by us and were either filed by Sandoz with all rights
fully transferred to us, or filed in our  sole  name, because  we acquired certain of our patents from
Sandoz, we must rely on their prior practices, with regard  to  the assignment  of such intellectual
property. Our and their assignment agreements  may  not  be  self-executing or  may be breached,  and we
may be forced to bring claims against  third parties, or defend claims  they may  bring  against us, to
determine the ownership of what we regard as our intellectual property.

If we  fail in prosecuting or defending any such claims, in  addition to paying  monetary  damages, we

may lose valuable intellectual property rights or personnel. Even if  we are  successful in  prosecuting or
defending against such claims, litigation could result in substantial costs and be a distraction to
management.

Intellectual property litigation could cause us to spend substantial  resources and could distract our personnel
from  their normal responsibilities.

Even if resolved in our favor, litigation or  other  legal proceedings relating to intellectual property

claims may cause us to incur significant expenses, and could distract our technical  and management
personnel from their normal responsibilities.  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
the ADSs. Such litigation or proceedings  could substantially increase our  operating losses  and reduce
the resources available for development,  sales, marketing or  distribution  activities. We may not have
sufficient financial or other resources to adequately  conduct such litigation or  proceedings. Some of  our
competitors may be able to sustain the  costs of such litigation or  proceedings more effectively than we
can because of their greater financial  resources. Uncertainties resulting from the initiation  and
continuation of patent litigation or other proceedings could have a material  adverse  effect on our
ability to compete in the marketplace.

If we are unable to protect the confidentiality of our trade  secrets,  our business and competitive  position would
be harmed.

In addition to seeking patents for some of  our  technology and products,  we also  rely on trade
secrets, including unpatented know-how,  technology and other proprietary information, to maintain our
competitive position. We seek to protect  these trade  secrets, in part,  by entering into non-disclosure
and confidentiality agreements with parties who have access  to  them, such as our employees, corporate
collaborators, outside scientific collaborators, contract  manufacturers,  consultants, advisors  and other
third parties. We also enter into confidentiality  and invention  or  patent assignment agreements with  our
employees and consultants. However, we cannot guarantee that we have executed these agreements
with each party that may have or have  had access  to  our trade secrets  or that the agreements  we have

executed will provide adequate protection.  Any party with whom  we have executed such an agreement
may breach that agreement and disclose our proprietary information,  including our trade secrets, and
we may not be able to obtain adequate  remedies  for such breaches.  Enforcing  a claim that a party
illegally disclosed or misappropriated  a trade secret  is difficult, expensive and time-consuming, and the
outcome is unpredictable. In addition, some courts  inside and  outside the United States  are less willing
or unwilling to protect trade secrets. If any of  our  trade secrets were to be  lawfully obtained or
independently developed by a competitor,  we would have no right to prevent  them, or  those to whom
they communicate it, from using that technology or information to compete with us. If any of our trade
secrets were to be obtained or independently developed  by  a competitor, our competitive position
would be harmed.

We have  not yet registered our trademarks in all of our potential  markets,  and  failure to  secure those
registrations could adversely affect our  business.

Our trademark applications may not  be  allowed  for registration, and our  registered trademarks

may not be maintained or enforced. During trademark registration proceedings, we  may receive
rejections. Although we are given an opportunity to respond  to  those rejections, we  may be unable to
overcome such rejections. 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.

Risks Related to Regulatory Approval and Marketing of Our Product Candidates and Other  Legal

Compliance Matters

Even if we complete the necessary non-clinical  studies and clinical  trials, the marketing approval process is
expensive, time-consuming and uncertain and  may  prevent us  from obtaining approvals for  the
commercialization of some or all of our  product candidates. If we  are not able  to obtain, or if there  are delays
in  obtaining, required regulatory approvals,  in particular in the United States or  the European Union,  we will
not  be able to commercialize our product  candidates, and  our ability to generate revenue will  be materially
impaired.

Our product candidates, including lefamulin, and the activities  associated with  their  development

and commercialization, including their  design, testing,  manufacture, safety, efficacy, recordkeeping,
labeling, storage, approval, advertising,  promotion, sale  and  distribution,  are subject to comprehensive
regulation by the FDA and by comparable authorities in other countries. Failure to obtain marketing
approval for a product candidate will  prevent us  from commercializing  the product  candidate. We  have
not received approval to market lefamulin or  any of our other product candidates  from regulatory
authorities in any jurisdiction.

We  have no experience in filing and supporting the  applications necessary to obtain marketing

approvals for product candidates and expect  to  rely on third-party  contract research organizations  to
assist us in this process. Securing marketing approval requires  the submission of extensive non-clinical
and clinical data and supporting information to various  regulatory authorities  for each  therapeutic
indication to establish the product candidate’s safety and efficacy.  Securing marketing approval  also
requires the submission of information  about the  product manufacturing process to, and inspection of
manufacturing facilities by, the regulatory authorities.  Regulatory authorities may determine that
lefamulin or any of our other product candidates are not effective or only moderately effective, or  have
undesirable or unintended side effects, toxicities,  safety profiles  or  other characteristics that preclude us
from obtaining marketing approval or  that prevent or limit  commercial use.

The process of obtaining marketing approvals  is expensive, may take many years, if approval  is
obtained at all, and can vary substantially based upon a variety of factors, including  the type, complexity
and novelty of the product candidates  involved. Changes in marketing approval policies during the
development period, changes in or the  enactment of additional statutes or  regulations, or  changes in
regulatory review for each submitted product  application,  may  cause delays in the approval or  rejection
of an application. For example, on June  23,  2016, eligible members of the electorate in the United
Kingdom decided by referendum to leave  the European  Union, commonly  referred to as ‘‘Brexit’’.
Because a significant proportion of the  regulatory framework in the  United Kingdom is derived from
European Union directives and regulations, the  referendum could materially change  the regulatory
regime applicable to the approval of  any of our  product candidates in the United Kingdom. In
addition, since the European Medicines Agency, or  EMA, is located in the United Kingdom, the
implications for the regulatory review process in the  European Union has not been clarified and could
result in relocation of the EMA or a disruption in  the EMA review  process.  The FDA and  comparable
regulatory authorities in other countries  have substantial  discretion in the approval process  and may
refuse to accept any application or may  decide that our data  are  insufficient for approval and require
additional preclinical, clinical or other  studies. In addition, varying interpretations  of the data obtained
from non-clinical and clinical testing could delay,  limit or prevent marketing approval of a product
candidate. Any marketing approval we  ultimately obtain may be limited or subject to restrictions  or
post-approval commitments that render  the approved product not  commercially viable.

Accordingly, if we or our collaborators  experience delays in obtaining approval or  if we or they fail
to obtain approval of our product candidates, the  commercial prospects for our product candidates may
be harmed and our ability to generate  revenues will  be  materially impaired.

Our failure to obtain marketing approval in  jurisdictions other than the  United States and Europe would
prevent our product candidates from being marketed in these other jurisdictions, and any approval we are
granted for our product candidates in the  United  States  and Europe would  not assure approval  of product
candidates in other jurisdictions.

In order to market and sell lefamulin  and our other product  candidates in jurisdictions  other than

the United States and Europe, we must obtain separate  marketing approvals and comply with
numerous and varying regulatory requirements. The  approval process varies among countries and can
involve additional testing. The time required to obtain approval may differ  from that required  to  obtain
FDA approval or approvals from regulatory authorities  in the European Union.  The regulatory
approval process outside the United States  and Europe generally  includes  all  of the risks associated
with obtaining FDA approval or approvals from regulatory  authorities  in the European Union. In
addition, some countries outside the  United States and Europe require approval  of the sales price of a
drug before it can be marketed. In many  countries,  separate  procedures must be followed to obtain
reimbursement and a product may not be approved  for sale in  the country until it is also approved  for
reimbursement. We may not obtain marketing, pricing or reimbursement approvals outside  the United
States and Europe on a timely basis,  if  at  all.  Approval by  the  FDA or regulatory authorities in the
European Union does not ensure approval by regulatory authorities in other  countries or jurisdictions,
and approval by one regulatory authority  outside the  United States and Europe does  not  ensure
approval by regulatory authorities in other  countries or jurisdictions  or  by  the FDA or regulatory
authorities in the European Union. We  may  not  be  able  to file for  marketing  approvals and may not
receive necessary approvals to commercialize our products in any  market. Marketing approvals  in
countries outside the United States and Europe do not ensure pricing approvals  in those  countries or
in any other countries, and marketing  approvals and pricing approvals  do not ensure  that
reimbursement will be obtained.

Even if we obtain marketing approvals  for our  product  candidates, the terms of approvals  and ongoing
regulation of our products may limit how we manufacture and market  our  products and compliance with such
requirements may involve substantial resources, which  could materially  impair our ability  to generate revenue.

Even if marketing approval of a product candidate is granted, an approved  product and its

manufacturer and marketer are subject to ongoing review  and extensive  regulation, including the
potential requirements to implement  a risk evaluation and mitigation  strategy or  to  conduct  costly
post-marketing studies or clinical trials and surveillance  to  monitor the safety  or efficacy of the product.
We  must also comply with requirements  concerning  advertising  and promotion  for any of our product
candidates for which we obtain marketing approval. Promotional communications with  respect to
prescription drugs are subject to a variety of legal and regulatory  restrictions and must be consistent
with the information in the product’s approved  labeling. Thus, we will not be able to promote any
products we develop for indications or  uses  for  which they are  not approved. In addition,
manufacturers of approved products  and  those manufacturers’  facilities are required to comply  with
extensive FDA requirements including  ensuring that  quality control and manufacturing  procedures
conform to cGMP, which include requirements relating to quality control and quality  assurance as  well
as the corresponding maintenance of  records  and documentation and reporting  requirements. We  and
our  contract manufacturers could be subject  to  periodic unannounced inspections  by  the FDA  to
monitor and ensure compliance with cGMP.

Accordingly, assuming we receive marketing  approval for one or more of our product candidates,

we and our contract manufacturers will continue to expend  time,  money and effort  in all areas of
regulatory compliance, including manufacturing,  production,  product surveillance and quality control. If
we are not able to comply with post-approval regulatory requirements,  we could have the  marketing
approvals for our products withdrawn by regulatory authorities and our  ability  to  market  any future
products could be limited, which could adversely affect our ability to achieve or sustain profitability.
Thus, the cost of compliance with post-approval  regulations may have a negative effect on our
operating results and financial condition.

Any product candidate for which we obtain  marketing approval will be subject to strict enforcement of
post-marketing requirements and we could be subject to substantial penalties, including  withdrawal of our
product from the market, if we fail to comply with  all regulatory requirements or  if we experience
unanticipated problems with our product  candidates, when and if any of them are approved.

Any product candidate for which we  obtain marketing approval, along with the  manufacturing
processes, post-approval clinical data,  labeling, advertising and promotional  activities for such product,
will be subject to continual requirements of  and review by  the FDA and other regulatory  authorities.
These requirements include, but are  not  limited to, restrictions governing promotion  of  an approved
product,  submissions of safety and other  post-marketing information and  reports, registration and
listing requirements, cGMP requirements  relating to manufacturing, quality  control, quality assurance
and corresponding maintenance of records and documents,  and requirements regarding the distribution
of samples to physicians and recordkeeping.  In addition, even if marketing approval  of a product
candidate is granted, the approval may  be  subject to limitations on the  indicated uses for  which the
product  may be marketed or to the conditions of approval.

The FDA and other federal and state agencies,  including  the U.S. Department  of  Justice, or  DOJ,

closely regulate compliance with all requirements governing prescription  drug products,  including
requirements pertaining to marketing  and  promotion  of  drugs in accordance  with the provisions of the
approved labeling and manufacturing of products in  accordance with  cGMP requirements. The FDA
and DOJ impose stringent restrictions on manufacturers’ communications regarding off-label use and if
we do not market our products for their approved  indications,  we may be subject  to  enforcement action
for off-label marketing. Violations of such requirements may lead to investigations alleging violations of

and state health care fraud and abuse laws as well  as state  consumer protection  laws.

Our failure to comply with all regulatory requirements, and later discovery of previously unknown

adverse events or other problems with our products,  manufacturers or manufacturing processes, may
yield various results, including:

(cid:127) litigation involving patients taking  our products;

(cid:127) restrictions on such products, manufacturers  or manufacturing processes;

(cid:127) restrictions on the labeling or marketing of a product;

(cid:127) restrictions on product distribution  or use;

(cid:127) requirements to conduct post-marketing studies or clinical trials;

(cid:127) warning or untitled letters;

(cid:127) withdrawal of the products from the  market;

(cid:127) refusal to approve pending applications or  supplements to approved  applications that we  submit;

(cid:127) recall of products;

(cid:127) fines, restitution or disgorgement of profits or revenues;

(cid:127) suspension or withdrawal of marketing approvals;

(cid:127) damage to relationships with any potential  collaborators;

(cid:127) unfavorable press coverage and damage to our  reputation;

(cid:127) refusal to permit the import or export of our products;

(cid:127) product seizure; or

(cid:127) injunctions or the imposition of civil or  criminal penalties.

Non-compliance by us or any future  collaborator with regulatory  requirements regarding safety
monitoring or pharmacovigilance, and with requirements related to the development of products for the
pediatric population, can also result  in significant financial  penalties. Similarly, failure to comply with
regulatory requirements regarding the protection of personal information  can also lead to significant
penalties and sanctions.

Non-compliance with European Union requirements regarding  safety monitoring or

pharmacovigilance, and with requirements  related to the development of  products for the pediatric
population, also can result in significant  financial penalties. Similarly, failure to comply with the
European Union’s requirements regarding  the protection of personal information  can also lead to
significant penalties and sanctions.

Governments outside the United States  tend  to impose strict  price controls, which may adversely affect  our
revenues,  if any.

In some countries, particularly the member states of the  European Union, the pricing of

prescription pharmaceuticals is subject  to  governmental control.  In these  countries, pricing negotiations
with governmental authorities can take considerable  time after  the receipt of marketing approval  for  a
product.  Also, there can be considerable  pressure by governments and other stakeholders  on prices and
reimbursement levels, including as part  of  cost containment measures. Political, economic  and
regulatory developments may further  complicate pricing  negotiations, and  pricing negotiations  may
continue after reimbursement has been obtained. Reference pricing used by various  European Union

member states and parallel distribution, or arbitrage  between low-priced and high-priced member
states, can further reduce prices. In some  countries,  we may be required to conduct a clinical trial or
other studies that compare the cost-effectiveness  of  our  product candidate  to  other  available  therapies
to obtain or maintain reimbursement  or pricing approval. Publication of discounts by third-party payors
or authorities may lead to further pressure on prices or  reimbursement levels within the  country  of
publication and other countries. If reimbursement of our products is unavailable or limited in  scope or
amount, or if pricing is set at unsatisfactory  levels, our business could be adversely affected.

The FDA’s agreement to a Special Protocol Assessment, or SPA, with respect to the study design  of  our first
Phase 3 clinical trial of lefamulin for CABP  does not guarantee any  particular outcome from  regulatory
review, including ultimate approval, and  may not lead  to a  faster development or regulatory review or approval
process.

We  reached agreement with the FDA in September 2015  on a SPA, which was later amended  in
April 2016, regarding the study design  of  our first Phase 3 clinical trial  of  lefamulin  for the  treatment
of CABP. The SPA process is designed to facilitate the  FDA’s review  and  approval of  drugs by allowing
the FDA to evaluate the proposed design and size of Phase 3 clinical trials  that  are intended  to  form
the primary basis for determining a product  candidate’s efficacy and safety. Upon specific request by a
clinical trial sponsor, the FDA will evaluate  the protocol  and respond to a  sponsor’s questions
regarding, among other things, primary efficacy endpoints, trial conduct and data analysis,  within
45 days of receipt of the request. The  FDA ultimately assesses  whether  the protocol design  and
planned analysis of the trial are acceptable to support regulatory  approval of the  product candidate
with respect to the effectiveness in the  indication studied.

Our agreement with the FDA regarding the SPA may not lead  to  faster development, regulatory

review or approval for lefamulin. Once the FDA and an applicant reach an agreement under the
special protocol assessment process regarding the design  and size of a  clinical trial, the  agreement
generally cannot be changed after the clinical trial  begins. Nevertheless, the FDA  may revoke or  alter a
SPA under defined circumstances, such  as changes in  the relevant data  or assumptions provided by the
sponsor  or the emergence of new public health concerns. A revocation or alteration in  our SPA  could
significantly delay or prevent approval of any marketing applications we submit for lefamulin. In
addition, any significant change to the  protocols  for our clinical trial  subject  to  the SPA would require
prior FDA approval, which could delay  implementation of such a change and the conduct of the trial.

Fast track designation by the FDA may not  actually lead to a faster development or regulatory review or
approval process and does not assure FDA  approval  of  our product candidate.

If a  drug is intended for the treatment of a serious  or life threatening condition and the drug

demonstrates the potential to address unmet medical need for this condition,  the drug sponsor may
apply  for FDA fast track designation. The  FDA  has designated  each of the IV  and oral formulations  of
lefamulin as a qualified infectious disease product, or  QIDP, and granted  fast  track designations to each
of these  formulations of lefamulin. However,  neither the QIDP nor the fast track  designation  ensures
that lefamulin will receive marketing approval or that approval will be granted within any particular
timeframe. We may also seek fast track designation for our other product candidates. We may not
experience a faster development process,  review or approval compared to conventional  FDA
procedures. In addition, the FDA may  withdraw  fast track designation if it believes  that  the designation
is no longer supported by data from  our clinical  development program.  Fast track  designation  alone
does not guarantee qualification for the  FDA’s priority review procedures.

Priority review designation by the FDA  may not  lead to a  faster regulatory review or  approval process  and, in
any event, does not assure FDA approval  of our product candidate.

If the FDA determines that a product candidate offers major  advances in  treatment or provides  a
treatment where no adequate therapy  exists,  the FDA may designate  the  product candidate  for priority
review. A priority review designation  means  that the FDA’s goal to review an  application  is six  months,
rather than the standard review period  of  ten months.  Because the FDA designated each of  the IV and
oral formulations of lefamulin as a QIDP,  lefamulin also  will receive priority review.  We  may also
request priority review for other product  candidates.  The  FDA has broad discretion with respect to
whether or not to grant priority review status to a  product candidate, so even if we  believe a particular
product  candidate is eligible for such  designation  or status, the FDA may decide not to grant it.
Moreover, a priority review designation does not necessarily  mean a faster regulatory  review process  or
necessarily confer any advantage with  respect to approval compared to conventional FDA procedures.
Receiving priority review from the FDA does  not guarantee approval within the six-month  review cycle
or thereafter.

Designation of our product candidate, lefamulin, as a Qualified Infectious Disease Product does not assure
FDA approval of this product candidate.

A QIDP is an antibacterial or antifungal drug intended to treat serious  or life-threatening

infections, including those caused by an  antibacterial  or antifungal  resistant pathogen, including novel
or emerging infectious pathogens or  certain ‘‘qualifying pathogens.’’ Upon the approval  of  an NDA for
a drug product designated by the FDA  as a QIDP, the product  is granted  an additional  period of five
years of regulatory exclusivity. Even though we  have received QIDP designation for  the IV and oral
formulations of lefamulin, there is no assurance  that  this product candidate  will be approved by the
FDA.

Our relationships with healthcare providers, physicians and third-party payors  will be subject to  applicable
anti-kickback, fraud and abuse and other healthcare  laws and regulations, which in the event of a violation
could expose us to criminal sanctions, civil penalties,  contractual damages, reputational harm and diminished
profits and future earnings.

Healthcare providers, physicians and  third-party  payors  will  play a primary role  in the

recommendation and prescription of any  product candidates, including lefamulin, for which we obtain
marketing approval. Our future arrangements with  healthcare providers, physicians and third-party
payors may expose us to broadly applicable fraud and abuse and other healthcare laws and  regulations
that may constrain the business or financial  arrangements and relationships through which  we market,
sell and distribute any products for which  we obtain marketing approval. Restrictions under applicable
federal and state healthcare laws and  regulations,  include the following:

(cid:127) the federal Anti-Kickback Statute  prohibits, among other things, persons from  knowingly and

willfully soliciting, offering, receiving or  providing remuneration,  directly or indirectly, in  cash or
in kind, to induce or reward, or in return for,  either the referral of an individual for, or the
purchase, order or recommendation  or arranging  of,  any  good or service, for which payment may
be made under a federal healthcare program such as Medicare and  Medicaid;

(cid:127) the federal False Claims Act imposes criminal and civil  penalties,  including through  civil
whistleblower or qui tam actions, against individuals  or entities for, among other things,
knowingly presenting, or causing to be presented, false or  fraudulent  claims  for payment by a
federal healthcare program or making  a false statement or record material to payment  of  a false
claim or avoiding, decreasing or concealing  an obligation to pay  money  to the  federal
government, with potential liability including mandatory  treble damages and  significant per-claim
penalties, currently set at $5,500 to $11,000 per false  claim;

Some state laws require pharmaceutical companies to comply with  the pharmaceutical  industry’s

voluntary compliance guidelines and the relevant  compliance guidance  promulgated  by  the federal
government and may require product  manufacturers to report  information  related to payments and
other transfers of value to physicians and  other healthcare  providers  or marketing expenditures.  State
and foreign laws also govern the privacy and security of health information in  some circumstances,
many  of which differ from each other  in significant  ways and often are  not  pre-empted by HIPAA, thus
complicating compliance efforts.

damages, fines, curtailment or restructuring of our operations could adversely  affect our financial
results. We are developing and implementing a corporate compliance  program designed to ensure  that
we will market and sell any future products  that  we successfully develop from our product candidates in
compliance with all applicable laws and  regulations, but  we cannot  guarantee  that  this program will
protect us from governmental investigations  or other actions  or  lawsuits stemming from a  failure to be
in compliance with such 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.

Efforts to ensure that our business arrangements with third parties  will comply with  applicable
healthcare laws and regulations will involve  substantial  costs. It is  possible that governmental  authorities
will conclude that our business practices may not  comply with current or  future statutes,  regulations or
case law involving applicable fraud and  abuse or other healthcare laws  and regulations. If our
operations are found to be in violation of any of  these laws or any other governmental regulations that
may apply to us, we may be subject to  significant civil, criminal  and administrative  penalties, damages,
fines, imprisonment, exclusion of products from government funded healthcare  programs, such as
Medicare and Medicaid, and the curtailment or restructuring  of  our operations.  If any of the physicians
or other  healthcare providers or entities with whom we  expect to do business is found to be not in
compliance with applicable laws, they  may be subject to criminal, civil  or administrative  sanctions,
including exclusions from government funded healthcare programs.

Current  and future legislation may increase  the difficulty and cost for us and  any collaborators to obtain
marketing approval of our product candidates and affect the prices we, or they,  may obtain.

In the United States and a number of foreign jurisdictions, there have been  a number  of legislative

and regulatory changes and proposed changes regarding  the healthcare  system that could prevent or
delay marketing approval of lefamulin or  any of our other  product candidates, restrict or regulate
post-approval activities and affect our ability to profitably sell any product candidates,  including
lefamulin, for which we obtain marketing  approval.  We  expect  that current laws, as  well as other
healthcare reform measures that may be adopted in the  future, may result in more  rigorous coverage
criteria and in additional downward pressure on  the price that  we, or  any collaborators, may receive  for
any approved products.

In March 2010, President Obama signed into law the Patient  Protection  and Affordable  Care Act,

as amended by the Health Care and Education Affordability Reconciliation Act, or  collectively the
ACA. Among the provisions of the ACA of potential  importance to our  business and  our product
candidates are the following:

(cid:127) an annual, non-deductible fee on any entity  that manufactures or imports specified branded

prescription products and biologic agents;

(cid:127) an increase in the statutory minimum rebates a manufacturer must pay under the Medicaid

Drug Rebate Program;

(cid:127) a new  methodology by which rebates owed by manufacturers under the Medicaid  Drug Rebate
Program are calculated for products  that are inhaled, infused,  instilled, implanted or injected;

(cid:127) expansion of healthcare fraud and abuse laws, including the civil  False  Claims Act and the

federal Anti-Kickback Statute, new government  investigative powers and enhanced penalties for
noncompliance;

(cid:127) a new  Medicare Part D coverage gap discount  program,  in which manufacturers must agree to
offer 50% point-of-sale discounts off negotiated prices of applicable  brand products to eligible
beneficiaries during their coverage gap period, as a  condition for  the manufacturer’s outpatient
products to be covered under Medicare  Part D;

(cid:127) extension of manufacturers’ Medicaid rebate liability to individuals enrolled in Medicaid

managed care organizations;

(cid:127) expansion of eligibility criteria for Medicaid programs;

(cid:127) expansion of the entities eligible for discounts under  the Public Health Service  pharmaceutical

pricing program;

(cid:127) new requirements to report certain  financial  arrangements  with physicians  and teaching

hospitals;

(cid:127) a new  requirement to annually report  product samples that  manufacturers and distributors

provide to physicians;

(cid:127) a new  Patient-Centered Outcomes  Research Institute to oversee, identify priorities in,  and
conduct comparative clinical effectiveness research, along  with funding for such research;

(cid:127) a new  Independent Payment Advisory Board, or IPAB, which has authority to recommend

certain changes to the Medicare program to reduce  expenditures by the program that could
result in reduced payments for prescription products; and

(cid:127) established the Center for Medicare  and  Medicaid Innovation within  CMS to test  innovative

payment and service delivery models.

In addition, other legislative changes have been proposed and adopted since the ACA  was  enacted.

These changes include the Budget Control Act  of 2011, which, among other things, led to aggregate
reductions to Medicare payments to providers of up  to  2% per fiscal year that started  in 2013 and, due
to subsequent legislative amendments to the statute, will  stay in effect  through 2025 unless additional
Congressional action is taken, and the American Taxpayer Relief Act of 2012,  which, among other
things, reduced Medicare payments to several types  of  providers and increased the  statute of limitations
period for the government to recover  overpayments to providers  from three  to  five years. These new
laws may result in additional reductions  in Medicare and other  healthcare funding and otherwise affect
the prices we may obtain for any of our  product candidates for which we may obtain regulatory
approval or the frequency with which any such product candidate is prescribed  or used. Further,  there
have been several recent U.S. Congressional inquiries and proposed bills designed to, among other
things, bring more transparency to drug pricing, review the  relationship between pricing and
manufacturer patient programs, and reform government  program  reimbursement methodologies for
drug products.

We  expect that the ACA, as well as other healthcare reform measures that  may be adopted in the

future, may result in additional reductions  in Medicare and  other healthcare  funding,  more rigorous
coverage criteria, new payment methodologies and additional downward  pressure  on the price that we
receive for any approved product and/or  the level  of  reimbursement physicians receive for
administering any approved product we  might bring  to  market.  Reductions in reimbursement  levels may
negatively impact the prices we receive  or the  frequency  with which our  products  are prescribed or
administered. Any reduction in reimbursement from Medicare or other government programs may
result in a similar reduction in payments from private payors.

In addition, with the new Administration and Congress, there will  likely be additional legislative

changes, including repeal and replacement  of  certain provisions of the ACA. It  remains  to  be  seen,
however, precisely  what the new legislation will provide,  when it will  be  enacted and what impact it will
have on the availability of healthcare  and  containing or  lowering the cost of healthcare. Such reforms
could have an adverse effect on anticipated revenue from product  candidates that we may successfully
develop and for which we may obtain marketing approval and may affect our overall financial  condition
and ability to develop or commercialize  product  candidates. For example, the President  and
congressional leaders have expressed interest in  repealing certain ACA  provisions  and replacing them
with alternatives that may be less costly and provide state Medicaid programs and private  health  plans
more flexibility. It is possible that these  repeal and replacement  initiatives, if enacted into law, could
ultimately result in fewer individuals having health insurance  coverage  or in  individuals having
insurance coverage with less generous benefits. The scope of potential future legislation  to  repeal and
replace ACA provisions is highly uncertain in many  respects,  and it  is possible  that  some of the  ACA
provisions that generally are not favorable for the research-based pharmaceutical industry could also be
repealed along with ACA coverage expansion provisions.

Legislative and regulatory proposals  have  also 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 United States Congress  of the
FDA’s approval process may significantly  delay or prevent marketing approval, as  well as subject  us and
any future collaborators to more stringent product  labeling and post-marketing testing  and other
requirements.

We are subject to anti-corruption laws,  as well  as  export control  laws, customs  laws, sanctions  laws and other
laws governing our operations. If we fail to comply with these laws, we could be subject to civil or criminal
penalties, other remedial measures and  legal  expenses, which could adversely affect our business, results of
operations and financial condition.

Our operations are subject to anti-corruption laws, including the U.S. Foreign Corrupt Practices
Act, or FCPA, and other anti-corruption  laws that  apply in  countries where we do  business  and may  do
business in the future. The FCPA and  these  other  laws generally prohibit us, our officers,  and our
employees and intermediaries from bribing, being bribed or making other prohibited payments to
government officials or other persons to obtain or  retain  business  or  gain some other business
advantage. We may in the future operate in jurisdictions that pose a high risk of potential FCPA
violations, and we may participate in collaborations and relationships  with third parties  whose  actions
could potentially subject us to liability under the FCPA or local anti-corruption laws. In addition, we
cannot predict the nature, scope or effect of future  regulatory requirements to which  our international
operations might be subject or the manner in that existing laws  might be administered or interpreted.

Compliance with the FCPA is expensive and difficult, particularly  in countries in  which corruption

is a recognized problem. In addition, the FCPA presents  particular challenges in  the pharmaceutical
industry, because, in many countries,  hospitals are operated by  the  government, and doctors and other
hospital employees are considered foreign  officials. Certain payments to hospitals  in connection with
clinical trials and other work have been deemed  to  be  improper payments to government  officials and
have led to FCPA enforcement actions.

We  are also subject to other laws and regulations governing  our international operations, including

regulations administered by the governments of the  United States, and authorities in  the European
Union, including applicable export control regulations, economic sanctions  on countries and persons,
customs requirements and currency exchange  regulations, collectively referred  to  as the trade control
laws.

There is  no assurance that we will be  effective  in ensuring our compliance  with all applicable
anti-corruption laws, including the FCPA  or other legal requirements, including trade  control  laws.  If
we are not in compliance with the FCPA and other anti-corruption laws  or trade control  laws,  we may
be subject to criminal and civil penalties,  disgorgement and other  sanctions and  remedial measures,  and
legal expenses, which could have an adverse impact on  our business, financial condition,  results of
operations and liquidity. Likewise, any  investigation  of  any potential violations of the  FCPA, other
anti-corruption laws or trade control laws  by U.S. or other  authorities could also  have an adverse
impact on our reputation, our business, results of operations and financial condition.

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.

We  are subject to numerous environmental, health and safety  laws and regulations, including  those

governing laboratory procedures and  the handling,  use, storage, treatment and  disposal of hazardous
materials and wastes. Our operations currently, and may in  the future,  involve  the use of  hazardous and
flammable materials, including chemicals and medical and biological materials, and produce  hazardous
waste products. Even if we contract with third  parties for the disposal of these  materials and  wastes,  we
cannot eliminate the risk of contamination or injury from  these  materials.  In the  event of
contamination or injury resulting from our use of hazardous materials or  disposal of hazardous wastes,
we could be held liable for any resulting  damages, and any  liability  could exceed our resources.

Although we maintain workers’ compensation insurance to cover  us for costs and expenses  we may

incur due to injuries to our employees resulting from the use of hazardous materials, this insurance
may not provide adequate coverage against potential  liabilities.  We also maintain a general liability
program for some of the risks, but our insurance  program  includes  limited  environmental damage

coverage, which has an annual aggregate  coverage limit of $2.0  million.  Although we maintain an
umbrella policy with an annual aggregate coverage limit of $10.0 million, which may provide some
environmental coverage, we do not maintain a separate policy covering environmental damages.

In addition, we may incur substantial  costs  to  comply  with current or future environmental, health
and safety laws and regulations. These current or  future  laws  and  regulations may impair our research,
development or production efforts. Failure  to  comply with  these  laws and regulations also may  result in
substantial fines, penalties or other sanctions.

Our employees may engage in misconduct  or other improper activities, including non-compliance with
regulatory standards and requirements, which  could cause  significant liability  for us and harm our reputation.

We  are exposed to the risk of employee fraud  or other misconduct, including intentional failures to

comply  with FDA regulations or similar  regulations  of comparable  non-U.S.  regulatory authorities,
provide accurate information to the FDA or comparable non-U.S.  regulatory  authorities, comply with
manufacturing standards we have established, comply with federal and state healthcare  fraud and abuse
laws and regulations and similar laws  and  regulations  established and enforced by comparable non-U.S.
regulatory authorities, 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, kickbacks, self-dealing and other abusive
practices. These 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.

Employee misconduct could also involve  the improper use of  information obtained during clinical

trials, which could result in regulatory  sanctions  and serious harm to our reputation.  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  be  in
compliance with such laws, standards  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 and  results of operations,  including the imposition of significant  fines
or other  sanctions.

We rely significantly on information technology and any failure, inadequacy, interruption or security  lapse of
that technology, including any cyber security incidents, could  harm our  ability to operate our  business
effectively.

Despite the implementation of security  measures, our internal computer systems and those of third

parties with which  we contract are vulnerable to damage  from cyber-attacks, computer viruses,
unauthorized access, natural disasters,  terrorism, war and telecommunication and electrical failures.
System failures, accidents or security breaches  could  cause  interruptions in our operations, and could
result in a material disruption of our clinical and commercialization activities and business operations,
in addition to possibly requiring substantial expenditures of resources to remedy.  The loss  of  clinical
trial data could result in delays in our  regulatory  approval efforts  and significantly increase our costs to
recover or reproduce the data. To the  extent that any disruption or security breach  were to result in a
loss of, or damage to, our data or applications, or inappropriate disclosure of  confidential or
proprietary information, we could incur liability and our product  research,  development and
commercialization efforts could be delayed.

Risks Related to Employee Matters and  Managing Growth

Our future success depends on our ability to retain our  chief  executive officer and other key executives and to
attract, retain and motivate qualified personnel.

We  are highly dependent on Dr. Colin Broom, our  Chief  Executive Officer, and the other principal

members of our management and scientific teams.  Although we  have formal employment agreements
with each of our executive officers, these  agreements do not prevent  our  executives  from terminating
their employment with us at any time. We  do not  maintain ‘‘key person’’ insurance  on any of our
executive officers. The unplanned loss of the services  of  any of  these persons might impede the
achievement of our research, development and commercialization objectives.

Recruiting and retaining qualified scientific, clinical,  manufacturing and sales and marketing
personnel, including in the United States  where  we plan to expand our  physical presence,  will  also be
critical to our success. We may not be  able to attract and retain  these  personnel on  acceptable terms
given the competition among numerous  pharmaceutical  and biotechnology companies  for similar
personnel. We also experience competition for the hiring  of scientific  and clinical personnel  from
universities and research institutions. In addition,  we rely on consultants and advisors, including
scientific and clinical advisors, to assist us in formulating our  research and development and
commercialization strategy. Our consultants and  advisors may be employed  by  employers other than us
and may have commitments under consulting or  advisory  contracts  with other entities that may  limit
their availability to us.

We expect to expand our development, regulatory and sales and marketing capabilities, and as a result, we
may encounter difficulties in managing our  growth, which could disrupt our  operations.

We  expect to experience significant growth in the  number of our  employees and  the scope of our

operations, particularly in the areas of  drug development, regulatory  affairs and  sales and marketing. To
manage our anticipated future growth,  we must continue to implement and  improve our managerial,
operational and financial systems, expand our facilities and continue  to  recruit and train additional
qualified personnel. Due to our limited financial  resources and  the  limited  experience  of our
management team in managing a company with such  anticipated growth, we  may not be able  to
effectively manage the expansion of our operations  or recruit and train  additional qualified  personnel.
The physical expansion of our operations  may lead  to  significant costs and  may divert our  management
and business development resources.  Any inability to manage growth  could  delay the execution  of  our
business plans or disrupt our operations.

Risks Related to Ownership of American Depositary Shares

An active trading market for the ADSs  may not be sustained.

Our ADSs began trading on the NASDAQ  Global Market on  September 18, 2015.  Given the
limited trading history of the ADSs, there is  a risk  that  an active trading market for  the ADSs will not
be sustained, which could put downward pressure on  the market price of the ADSs and thereby affect
the ability of our security holders to sell their ADSs.

The price of the ADSs may be volatile and  fluctuate substantially.

The trading price of the ADSs has been  and  is likely  to  continue to be volatile. The stock market

in general and the market for smaller  biopharmaceutical  companies in  particular  have experienced
significant volatility that has often been  unrelated to the operating performance  of  particular
companies. The market price for the  ADSs may be influenced by  many factors, including:

(cid:127) the other factors described in this ‘‘Risk Factors’’ section.

In the past, following periods of volatility in the  market  price of a  company’s securities,  securities
class-action litigation has often been  instituted against that company. We  also may face  securities class-
action litigation if we cannot obtain regulatory approvals for or if we otherwise fail  to  commercialize
lefamulin or any of our other product candidates. Such litigation, if  instituted  against us, could cause us
to incur substantial costs to defend such claims  and divert management’s attention and  resources.

Our senior managers, supervisory board members and  principal  shareholders, if they choose to act together,
have the ability to control most matters  submitted to  shareholders for  approval.

Our senior managers and supervisory  board  members, combined with  our  shareholders, and  their
respective affiliates who owned more  than  5% of  our  outstanding common shares as of December 31,
2016 in the aggregate, beneficially owned approximately  76.9% of our share  capital. As a  result, if these
shareholders were to choose to act together, they  would be able to control most matters  submitted to
our  shareholders for approval, as well  as our management and affairs.  For example,  these persons, if
they choose to act together, would control the election  of supervisory  board members  and approval  of
any merger, consolidation or sale of  all  or  substantially  all  of our  assets.

ADSs representing only a relatively small  percentage of our common shares are publicly traded, which may
limit the liquidity of the ADS and may  have a material  adverse effect  on the price of the ADSs.

As of December 31, 2016 only 23.1%  of our common  shares were beneficially owned by parties
other than our supervisory board members, senior management,  shareholders holding 5%  or more of
our  common shares, and their respective affiliates. As a  result, ADSs representing  only  a relatively
small number of our common shares  are  actively traded  in the public market. Limited liquidity may
increase the volatility of the price of  the ADSs.

The ADSs and our common shares do  not  trade  on any exchange outside of the United States.

Our ADSs are listed only in the United States on The NASDAQ Global  Market, and we have  no

plans to list the ADSs or our common  shares in any other  jurisdiction.  As a result, a holder of ADSs or

common shares outside of the United States may  not  be  able  to  effect transactions in the  ADSs as
readily as the holder may if the ADSs were listed on  an exchange in that holder’s  home jurisdiction.
Additionally, a holder of common shares  may not be able  to effect transactions  in our common shares
without depositing such common shares  with our depositary in exchange for  the issuance of ADSs
representing such common shares.

The sale of a substantial number of ADSs may cause the market  price of the ADSs to  decline.

Sales of a substantial number of our  common shares or ADS, or the perception in the  market  that

these sales could occur, could reduce the  market  price of the  ADSs.  Each  ADS represents
one tenth (1/10) of a common share and  we had  2,719,695 common shares outstanding as of
December 31, 2016, of which 2,242,302 shares are  represented by  22,423,020 American Depositary
Shares. Moreover, holders of an aggregate  of  951,306 common shares have rights, subject to specified
conditions, to require us to file registration statements covering their  shares  or to include their shares
in registration statements that we may file  for  ourselves or  other shareholders. Once we register these
shares, they can be freely sold in the public market upon issuance, subject to volume limitations
applicable to affiliates. To the extent any of these shares are sold into the market, particularly in
substantial quantities, the market price  of the  ADSs could decline.

Future issuances of common shares pursuant to our  equity incentive plans  could  also result  in
additional dilution of the percentage ownership  of  our shareholders. We  filed  a registration statement
on Form S-8 on November 18, 2015 that  covers an aggregate of  201,632 common shares reserved for
issuance pursuant to our equity incentive  plans.  Additionally, the majority of common shares that may
be issued under our equity compensation  plans also remain subject to vesting in tranches  over a
four-year  period. As of December 31,  2016, an aggregate of 53,311  options  to  purchase  our common
shares had vested and become exercisable.

If a  large number of the ADSs are sold  in the public market after  they become eligible for sale,

the sales could reduce the trading price of the ADSs and impede our ability to raise future capital.

We are an ‘‘emerging growth company’’,  and the reduced  disclosure requirements  applicable  to emerging
growth companies may make the ADSs less  attractive to investors.

We  are an ‘‘emerging growth company,’’ as  that term is used in the Jumpstart  Our Business

Startups Act of 2012, or the JOBS Act,  and may remain an  emerging growth  company until
December 31, 2020 or such earlier time  that we are no longer an emerging  growth company. For  so
long as we remain an emerging growth  company, we  are permitted and may take advantage of specified
reduced reporting and other burdens  that  are otherwise applicable generally to public companies. These
provisions include:

(cid:127) an exemption from compliance with  the auditor  attestation requirement  of Section 404  of  the

Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, on the design  and effectiveness of our
internal controls over financial reporting;

(cid:127) an exemption from compliance with  any requirement that the Public  Company Accounting

Oversight Board may adopt regarding mandatory audit firm rotation or a supplement to the
auditor’s report providing additional information about  the audit and the financial statements;

(cid:127) reduced disclosure about the company’s executive compensation arrangements; and

(cid:127) exemptions from the requirements to obtain a  non-binding  advisory vote on executive

compensation or a shareholder approval of any golden  parachute arrangements.

advantage of these provisions until December  31, 2020 or  such earlier time that we are no longer  an

emerging growth company. We would cease to be an  emerging growth  company upon the earlier to
occur of: the last day of the fiscal year  in  which we  have more than $1 billion in annual revenues; the
date  we qualify as a ‘‘large accelerated  filer,’’ with more than $700 million in market value of our share
capital held by non-affiliates; or the issuance by us of  more than  $1 billion of  non-convertible debt over
a three-year period.

We  may choose to take advantage of  some, but not all,  of  the available benefits  under the JOBS
Act. We cannot predict whether investors will find the  ADSs  or common shares less attractive if we  rely
on such exemptions. If some investors find  the ADSs less attractive as  a result,  there may be a  less
active  trading market for the ADSs and  the market price of the ADSs may be more  volatile.

In addition, the JOBS Act also provides that an emerging growth company can take advantage of
an extended transition period for complying with new  or revised accounting standards.  This allows  an
emerging growth company to delay the adoption of certain accounting standards until those standards
would otherwise apply to private companies. We have irrevocably elected not to avail  ourselves of this
exemption and, therefore, we will adopt  new or revised accounting standards on the relevant  dates on
which  adoption of such standards is required  for  other  public  companies that are not emerging growth
companies.

We lost our foreign private issuer status on  January 1, 2017,  which  requires  us  to comply with the Exchange
Act’s domestic reporting regime, as well  as NASDAQ’s domestic  company corporate governance requirements,
which we expect will cause us to incur significant legal, accounting and other  expenses.

We  determined that, as of June 30, 2016,  we no longer  qualified as  a  ‘‘foreign private issuer’’
under the rules and regulations of the  SEC. As  a result, beginning January 1, 2017,  our future annual
filings with the SEC will be made on  Form 10-K (including  our annual  report  for the  year  ending
December 31, 2016) rather than on Form  20-F. In addition, commencing  on January 1, 2017, we also
expanded our reporting to be consistent with that of a  domestic filer in  the United  States,  including
filing quarterly reports on Form 10-Q and  current reports on Form  8-K.  In  addition, we will prepare
our  financial statements in accordance with U.S. GAAP, rather than  IFRS, and we will adopt new or
revised U.S. GAAP accounting standards on the  relevant  dates on which  adoption  of such standards  is
required for other public companies that  are not emerging growth companies.  We  also are  now subject
to SEC rules governing the solicitation of  proxies, consents or authorizations in respect of a  security
registered under the Exchange Act; the provisions  of  Regulation Fair Disclosure,  which regulate the
selective disclosure of material information; and the  sections of the Exchange  Act  requiring insiders  to
file public reports of their share ownership and trading  activities and establishing insider liability for
profits realized from any ‘‘short-swing’’ transactions in  our equity  securities. In addition, we are now
subject to the NASDAQ Stock Market listing requirements  applicable to domestic issuers.

We  expect the regulatory and compliance costs  to  comply  with the  reporting and  corporate
governance requirements applicable to  a  domestic issuer  will be significantly  higher than the costs  we
have historically incurred as a foreign  private issuer. As a result, we expect that the loss of our foreign
private  issuer status will increase our legal  and financial compliance costs and may make some activities
highly time consuming and costly. We also expect that our loss  of  foreign private issuer status may
make it more difficult and expensive for  us  to  obtain  director  and officer liability insurance, and  we
may be required to accept reduced coverage or incur  substantially  higher  costs  to  obtain  coverage.
These rules and regulations could also make it more difficult for us  to  attract  and retain qualified
members of our supervisory board.

We have  broad discretion in the use of  our  funds  and may  not use  them  effectively.

Our management has broad discretion in  the application of our available funds and could spend
the funds in ways that do not improve  our  results of operations or enhance the value of the  ADSs. The

failure by our management to apply these funds effectively  could result in financial losses  that  could
have a material adverse effect on our  business, cause the price  of the ADSs to decline  and delay the
development of our product candidates.  Pending their use, we may invest  funds in a manner that does
not produce income or that loses value.

We incur increased  costs as a result of operating as  a public company, and  our  management  is required  to
devote substantial time to new compliance initiatives and corporate governance practices.

As a public company we incur, and particularly  after we are  no longer an emerging  growth

company, we will incur significant legal, accounting and other expenses that we did not incur as a
private  company. In addition, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and
Consumer Protection Act, the listing requirements  of  The NASDAQ  Global Market  and other
applicable securities rules and regulations  impose  various requirements on public companies, including
establishment and  maintenance of effective disclosure and financial controls  and corporate governance
practices. Our management and other personnel  need  to  devote a substantial  amount  of  time to these
compliance initiatives. Moreover, these  rules and regulations  have increased our legal  and financial
compliance costs and make some activities more time-consuming and costly. For example, these rules
and regulations have made it more expensive for us to obtain director and officer liability insurance,
which  in turn could make it more difficult  for  us to attract and retain qualified members of  our
supervisory board.

For as long as we remain an emerging growth company, we may take advantage of certain

exemptions from various reporting requirements that  are applicable to other public companies  that  are
not emerging growth companies as described elsewhere in this ‘‘Risk Factors’’  section.  We may  remain
an emerging growth company until December 31,  2020, although  if the market  value of  our share
capital that is held by non-affiliates exceeds  $700 million as of any June 30  before that time or if we
have annual gross  revenues of $1 billion  or more in any fiscal year, we  would cease to be an emerging
growth company as of December 31 of the  applicable  year. We also would  cease to be an  emerging
growth company if we issue more than $1  billion  of non-convertible  debt  over  a three-year period.

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,  security holders could lose confidence in
our financial and other public reporting, which would harm  our  business  and the trading price  of  the ADSs.

Effective internal control over financial reporting is  necessary for us  to  provide reliable  financial
reports and, together with adequate  disclosure controls  and  procedures, is 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,
as and when required, conducted in connection with  Section 404 of the Sarbanes-Oxley  Act, or
Section 404, or any subsequent testing by our independent registered public accounting firm, as and
when required, may reveal deficiencies in our  internal control  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 trading price of  the ADSs.

Pursuant to Section 404, we will be required to furnish  a report by our management  on our
internal control over financial reporting. However, as  an emerging  growth company, we will not be
required to include an attestation report  on internal control over  financial reporting issued by our
independent registered public accounting  firm until we are no longer an emerging growth  company. To
achieve compliance with Section 404  within the  prescribed  period, we are  engaged in  a process to
document and evaluate our internal control over  financial reporting, which is both costly and
challenging. In this regard, we will need to continue to dedicate internal resources, potentially engage

outside consultants and adopt a detailed work  plan to assess and document  the adequacy of  internal
control over financial reporting, continue  steps to improve control processes as appropriate, validate
through testing that controls are functioning as  documented  and implement  a continuous reporting and
improvement process for internal control  over financial  reporting. Despite our efforts, there is a  risk
that we will not be able to conclude within  the prescribed timeframe that our internal control  over
financial reporting is effective as required by Section 404.  This could result  in an adverse reaction  in
the financial markets due to a loss of  confidence  in the reliability  of  our financial statements.

United States investors may have difficulty enforcing civil liabilities against us, our  supervisory board
members or senior management and the experts named in this Annual Report.

We  are incorporated under the laws  of Austria,  and  our registered  offices and a substantial portion

of our assets are located outside of the  United States.  In  addition, a member of our supervisory  board
is a resident of a jurisdiction other than  the United States. As a result, it may not be possible to effect
service of process on such person or us  in  the United States or to enforce  judgments obtained in courts
in the United States against such person  or us based on civil liability provisions of the securities laws of
the United States. In addition, it is questionable whether  a court in Austria  would accept jurisdiction
and impose civil liability if proceedings  were commenced in such court predicated  solely upon U.S.
federal securities laws. As the United  States  and Austria do not currently have  a treaty  providing for
reciprocal recognition and enforcement of  judgments in  civil  and commercial matters  (other than
arbitration awards in such matters), a final judgment  for payment of money rendered by a  federal or
state court in the United States based  on civil liability, whether  or not predicated solely upon  U.S.
federal securities laws, will not be enforceable, either in  whole or in part, in Austria. However, if the
party in whose favor such final judgment  is rendered brings  a  new  suit in a competent court in Austria,
such party may submit to the Austrian  court the  final  judgment rendered  in  the United  States.  Under
such circumstances, a judgment by a  federal or  state court of the  United  States against the company
will be regarded by an Austrian court  only  as evidence of the  outcome  of the dispute to which such
judgment relates, and an Austrian court  may  choose to re-hear the dispute. In addition, awards of
punitive damages in actions brought  in the United  States or elsewhere may be unenforceable in
Austria. An award for monetary damages under the  securities laws of  the  United States would be
considered punitive if it does not seek to compensate the claimant for  loss or  damage suffered  and is
intended to punish the defendant.

Holders of ADSs may not have the same voting rights as  the holders of our common shares and may not
receive voting materials in time to be able  to  exercise their right to vote.

Holders of the ADSs may not be able to exercise voting  rights attaching  to  the common shares
evidenced by the ADSs. Holders of the ADSs will have  the right to instruct the depositary with  respect
to the voting  of the common shares represented by the ADSs. If we tell the depositary  to  solicit your
voting instructions, the depositary is required to endeavor to carry out your instructions.  If we  do not
tell the depositary to solicit your voting instructions (and  we are  not  required to do  so), you  can still
send instructions, and, in that case, the  depositary  may, but  is not required  to,  carry out  those
instructions. You may not receive voting  materials in time to instruct the depositary to vote, and  it is
possible that you, or persons who hold their ADSs  through brokers, dealers or other third parties, will
not have the opportunity to exercise a  right  to  vote.

Holders of ADSs may not have the same rights  to participate in subscription  rights  offering as holders  of our
common shares.

Under Austrian law, whenever we issue  new common  shares, we are required by law, subject to
certain limited exceptions, to grant subscription rights to all holders of our  common shares,  giving them
the right to purchase a sufficient number  of new common shares  to  maintain their existing ownership

percentage. Although we may take steps  to  offer common  shares (in the  form of ADSs) to holders of
ADSs in connection with any future  rights offering,  we are not required  to  do  so. We also are not
required to ensure that holders of ADSs have an  opportunity to participate in any  rights offering on
the same terms as holders of our common  shares.

Holders of ADSs may not receive distributions on our  common shares  represented by the ADSs or any  value
for  them if it is illegal or impractical to make them available to  such holders.

The depositary for the ADSs has agreed to pay to holders of ADSs or distribute the  cash

dividends or other distributions it or  the custodian receives on  our common shares or  other deposited
securities after deducting its fees and expenses. Holders  of ADSs will receive these distributions in
proportion to the number of our common shares their ADSs represent. However, in accordance with
the limitations set  forth in the deposit  agreement, it  may be  unlawful or impractical  to  make  a
distribution available to holders of ADSs.  We  have no obligation to take any  other action to permit the
distribution of the ADSs, common shares,  rights or  anything else to holders of the  ADSs. This means
that holders of ADSs may not receive  the distributions we  make on our common shares or any value
from them if it is unlawful or impractical  to  make them available to such holders. These restrictions
may have a material adverse effect on  the value  of the ADSs.

We do not expect to pay dividends in the  foreseeable future.

We  have not paid any dividends on our common shares since our incorporation.  Even if future
operations lead to significant levels of distributable profits,  we  currently  intend that earnings,  if  any,
will be reinvested in our business and  that dividends will not be paid until we  have an established
revenue stream to support continuing  dividends. Payment of  future dividends to security  holders will  be
at the discretion of the management board, subject to the approval of the supervisory board after
taking into account various factors including our business prospects, cash requirements, financial
performance, debt  covenant limitations and new product development.  In  addition, Austrian law
imposes limitations on our ability to  pay dividends. Under Austrian law, a company  may only pay
dividends if the distribution of dividends  is proposed by the management board  and the  supervisory
board and resolved by the company’s  shareholders  at a  general meeting.  Our ability to pay  dividends  is
assessed by our management board based primarily on our unconsolidated financial statements
prepared in accordance with the Austrian Commercial  Code (Unternehmensgesetzbuch). Dividends
may be paid only after the relevant balance  sheet date from  the  net profit  (Bilanzgewinn) recorded in
our  unconsolidated annual financial statements as approved by our  supervisory  board or  by  our
shareholders at a general meeting. In determining the  amount  available  for distribution, the annual  net
income must be adjusted to account  for any accumulated undistributed net profit  or loss  from previous
years as well as for withdrawals from  or  allocations to reserves. Certain reserves must be established by
law, and allocation to such reserves must therefore be deducted from the annual  net income to
calculate the annual net profit.

We are exposed to risks related to currency  exchange  rates.

A significant portion of our expenses  are denominated in currencies other than the U.S. dollar.
Because our financial statements are presented in U.S. dollars, changes in currency exchange rates have
had and could have a significant effect  on our operating results. Exchange rate fluctuations between
foreign currencies and the U.S. dollar create risk in several ways, including the following:

(cid:127) weakening of the U.S. dollar may  increase the U.S. dollar cost of overseas research and

development expenses;

(cid:127) strengthening of the U.S. dollar may decrease  the value of our revenues denominated in other

currencies;

The rights of our shareholders may differ from the  rights typically offered to shareholders of  a U.S.
corporation. We are organized as a stock  corporation (Aktiengesellschaft) and  incorporated under Austrian
law.

The rights of holders of our common  shares and, therefore, certain of the rights of  holders of the
ADSs, are governed by Austrian law,  including the  provisions  of  the Austrian Stock  Corporation Act,
and by our articles of association. These rights differ  in important respects  from the rights  of
shareholders in typical U.S. corporations. These differences include, in  particular:

(cid:127) Under Austrian law, certain important resolutions, including, for  example, capital decreases,
mergers, conversions and spin-offs, the issuance of  convertible bonds or bonds with  warrants
attached and the dissolution of the stock corporation (apart from  insolvency and certain other
proceedings), require the vote of a 75%  majority (and, in some cases, as high  as a 90%  majority)
of the capital present or represented  at the  relevant  general meeting  of  shareholders. Therefore,
the holder or holders of a blocking minority of 25% or, depending on  the attendance  level at
the general meeting, the holder or holders of a  smaller percentage of the shares in an  Austrian
stock corporation may be able to block any such votes, possibly to our detriment  or the
detriment of our other shareholders.

(cid:127) As a general rule under Austrian law, a shareholder  has no  direct recourse  against the members
of the management board or supervisory board of an Austrian stock corporation in the  event
that it is alleged that any of them have breached their duty  of loyalty or duty of care to the
Austrian stock corporation. Apart from insolvency or other  special circumstances, only the
Austrian stock corporation itself has  the right to claim damages from members of  the
management or supervisory board. An  Austrian stock  corporation may  waive or  settle these
damages claims only after five years, if  the shareholders  approve  the waiver  or settlement at the
general meeting with a simple majority  of the votes cast and no group of shareholders holding,
in the aggregate, at least 20% (and  in  some cases,  5%)  of  the Austrian  stock  corporation’s share
capital objects to such waiver or settlement and has its opposition  formally noted in the  minutes
of the general meeting. However, Austrian courts acknowledge a waiver or settlement of claims
for damages earlier if all shareholders consent to such  waiver.

We may  be classified as a passive foreign  investment company  for our tax year ending December 31, 2017,
which may result in adverse U.S. federal income tax consequence  to  U.S.  holders.

Based on our estimated gross income and  average value of our gross  assets and the nature of  our

business, we do not believe that we were a  ‘‘passive foreign investment company,’’  or PFIC, for U.S.
federal income tax purposes for our tax years ended  December 31,  2014, 2015  or 2016, although  for
our  tax year ended December 31, 2016,  our calculations indicate that we were  close to being so
classified, and to the extent of any differences in its own  calculations, the U.S.  taxing authority might
conclude that we were in fact a PFIC  for that  year. A corporation  organized outside the United States
generally will be classified as a PFIC for  U.S. federal income tax purposes (1) in any taxable year in
which  at least 75% of its gross income  is passive income or  on average at  least  50% of the gross value
of its assets is attributable to assets that produce passive income or are held for the production of
passive income and (2) as to a given holder who was a holder  in such year and regardless of such
corporation’s income or asset composition, in any subsequent taxable  year  unless, as  to  that  holder,
certain elections are made that can entail  substantial tax costs to that  holder.  Passive  income  for this
purpose generally includes dividends,  interest, royalties,  rents and gains  from commodities and

securities transactions. Our status in  any  taxable  year  will depend  on our assets  and activities in each
year, and because this is a factual determination made annually after the end of each  taxable  year,
there can be no assurance that we will  not  be  considered a PFIC for  the current taxable  year or  any
future taxable year. The market value of  our assets may be determined in  large part  by  reference to the
market price of the ADSs, which may  fluctuate considerably given  that market  prices of biotechnology
companies have been especially volatile.  If we were to be treated as  a  PFIC for the tax year  ending
December 31, 2017, or any other future  taxable year during  which a U.S. holder held  the ADSs,
however, certain adverse U.S. federal income tax consequences could apply to the U.S. holder. We
currently intend to make available the  information necessary  to  permit a U.S. holder to make a  valid
QEF election, which may mitigate some  of the adverse  U.S. federal income tax consequences  that
could apply to a U.S. holder of ADSs.

record of the ADSs. The number of record holders may  not  be  representative of the number of
beneficial owners because many of our common  shares and ADSs are held by depositories, brokers or
other nominees, including the Bank of  New York Mellon, which  serves as the depositary  for our
common shares under our American  Depositary Receipt program.

equity securities during the year ended December 31, 2016  that were not  registered under the
Securities Act of 1933, as amended, or  the Securities Act.

Purchase of Equity Securities

We  did not purchase any of our registered equity  securities during the  period covered by this

Annual Report on Form 10-K.

Use of Proceeds from Registered Securities

We  effected the initial public offering  of our American Depositary  Shares, or ADSs, each

representing one tenth (1/10) of a common share,  through a Registration Statement on Form F-1  (File
No. 333-205073) that was declared effective  by the Securities  and Exchange Commission  on
September 17, 2015. On September 23, 2015, we completed  the sale  of 9,000,000 ADSs, representing
900,000 of our common shares, at a public offering price of  $10.25 per ADS, before underwriting
discounts. In addition, we granted the underwriters a 30-day option to purchase up to 1,350,000

additional ADSs to cover over allotments,  if any. On September 30, 2015, we completed  the additional
sale of 1,350,000 ADSs under this option at a price to the public  of $10.25 per ADS,  resulting in
aggregate net proceeds to us of approximately $92.4 million after deducting underwriting discounts and
commissions of $7.4 million and offering expenses of $6.3  million. None  of  the underwriting discounts
and commissions or other offering expenses were paid to directors  or officers  of  ours  or their associates
or to persons owning 10% or more of  any class  of our equity securities or to any  affiliates  of ours.
Leerink Partner LLC, RBC Capital Markets,  LLC, Needham  & Company, LLC and  Wedbush
PacGrow Inc. were the underwriters  for our initial public  offering.

There has been no material change in our planned use of the net proceeds from our initial  public

offering as described in our final prospectus  filed  with the SEC  pursuant to Rule 424(b)(4) on
September 21, 2015.

Our management board retains broad discretion in the allocation and use  of the net proceeds of

our  initial public offering.

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

RESULTS OF OPERATIONS

You should read the following discussion and analysis of  our financial condition and results of

operations together with our historical consolidated financial statements and  the related notes thereto
appearing elsewhere in this Annual Report.  Some of the information contained  in  this discussion and
analysis or set forth elsewhere in this Annual Report,  including  information  with respect  to our  plans and
strategy for our business and related financing, includes forward-looking statements that involve risks and
uncertainties. As a result of many factors, including those factors set forth in  the ‘‘Risk Factors’’  section of
this Annual Report, our actual results could differ materially  from the results  described in or  implied by the
forward-looking statements contained in  the following  discussion and analysis.

Overview

We are a clinical stage biopharmaceutical company  engaged in the  research and  development of

novel anti-infective agents to treat serious infections,  with a focus  on the pleuromutilin class of
antibiotics. We are developing our lead product candidate, lefamulin, to be the  first  pleuromutilin
antibiotic available for systemic administration  in humans.  We are developing  both  intravenous, or IV,
and  oral formulations of lefamulin for the treatment  of  community-acquired bacterial pneumonia,  or
CABP and intend to develop lefamulin for additional indications other than pneumonia. We have
initiated two pivotal, international Phase  3 clinical trials of lefamulin for the treatment of moderate to
severe CABP. These are the first clinical  trials  we  have conducted with lefamulin for the treatment  of
CABP. We initiated the first of these trials,  which we refer to as  LEAP 1, in  September 2015  and
initiated the second trial, which we refer to as LEAP 2, in April  2016. Based on our estimates
regarding patient enrollment, we expect to have top-line  data available from LEAP1 in  the third
quarter of 2017 and top-line data available from LEAP  2 in the first  quarter of  2018. If the  results of
these trials are favorable, including achievement of the primary  efficacy endpoints of  the trials, we
expect to submit applications for marketing approval for lefamulin for the treatment  of CABP in both
the United States and Europe in 2018.

We have completed a Phase 2 clinical trial of lefamulin for  acute  bacterial skin and skin structure

infections, or ABSSSI, and seventeen Phase  1 clinical  trials of lefamulin in which we exposed healthy
subjects to single or multiple doses of  IV or  oral lefamulin.  We plan to pursue additional opportunities
for lefamulin, including a development program  for use in  pediatric  patients and  potentially for the
treatment of ABSSSI. In addition, as an  antibiotic with  potent activity  against a wide variety of
multi-drug resistant pathogens, including MRSA, we may  explore development  of lefamulin in further
indications, including ventilator-associated bacterial  pneumonia, or VABP and  hospital-acquired
bacterial pneumonia, or HABP, sexually transmitted infections, or STIs,  osteomyelitis, prosthetic joint
infections. Through our research and development  efforts, we have also  identified a topical
pleuromutilin product candidate, BC-7013, which has  completed a Phase  1 clinical  trial.

We were incorporated in October 2005 in  Austria under  the name Nabriva  Therapeutics
Forschungs GmbH, a limited liability company organized under Austrian law, as  a spin-off from
Sandoz  GmbH and commenced operations in February 2006.  In 2007, we transformed  into  a stock
corporation (Aktiengesellschaft) under the name Nabriva Therapeutics AG.  In  2014, we  established our
wholly owned U.S. subsidiary, which began  operations in August  2014. Since inception, we have
incurred significant operating losses. As  of  December  31, 2016, we had  an accumulated deficit  of
$204.8 million. To date, we have financed  our operations primarily through our 2016  rights offering, our
2015 initial public offering, private placements of our common shares, convertible  loans and research
and development support from governmental grants and loans. We  have devoted substantially all of  our
efforts to research and development,  including clinical  trials. Our ability to generate  profits from
operations and remain profitable depends  on our  ability to  successfully  develop  and commercialize
drugs that generate significant revenue.

We  expect to continue to incur significant expenses and  increasing operating losses for  at least the

next several years. We expect our expenses to increase  substantially in connection  with our ongoing
activities, particularly as we continue the  development of and potentially seek marketing approval  for
lefamulin and, possibly, other product  candidates  and continue our  research activities. Our expenses
will increase if we  suffer any delays in our  Phase 3 clinical program for lefamulin for CABP, including
delays in enrollment of patients. If we  obtain marketing approval  for lefamulin  or any  other product
candidate that we develop, we expect  to  incur significant commercialization expenses related  to  product
sales, marketing, distribution and manufacturing.  Furthermore, we expect  to  incur  additional costs
associated with operating as a public company.

Based on our current plans, we do not  expect to generate significant revenue  unless and until we

obtain marketing approval for, and commercialize, lefamulin. We do not expect to obtain marketing
approval before 2019, if at all. Accordingly, we will need  to obtain substantial additional funding in
connection with our continuing operations. Adequate additional financing may not be available to us on
acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we
could be forced to delay, reduce or eliminate our research and development programs or any future
commercialization effort.

December 2016 Financing

On December 19, 2016, we completed a rights offering  and  a  related  underwritten  offering for the
sale of an aggregate of 588,127 common shares resulting in  aggregate  gross proceeds of approximately
$24.8 million and net proceeds to us  of approximately  $20.6 million, after deducting  underwriting fees
and offering expenses.

In the rights offering, holders of American Depositary  Shares, or ADSs,  received 0.276  ADS rights

for each  ADS owned of record on November 29, 2016. One ADS right  entitled an ADS  holder  to
subscribe for and purchase one new ADS at the subscription  price of $4.32  per  ADS, the U.S. dollar
equivalent of  A4.014 per ADS. An aggregate of 1,592,750 ADSs, representing 159,275 common  shares,
were subscribed for by holders of ADSs. Each ADS represents one  tenth of a  common share.

In the rights offering, holders of common shares received  the common share  right to subscribe for

and  purchase 0.276 new common shares, at a subscription price of A40.14 per new common share for
each  common share owned of record  on  November  29, 2016. An aggregate of 102,077 new common
shares were subscribed for by holders of common shares.

Pursuant to an underwriting agreement that we entered into with Cantor Fitzgerald & Co., dated
December 14, 2016, Cantor Fitzgerald  &  Co. agreed to purchase 326,775 common shares, representing
all of the unsubscribed common shares  in the  rights offering, at  a purchase price  of A40.14 per common
share for purposes of resale of ADSs  representing such unsubscribed common shares.

2015 Initial Public Offering

On September 23, 2015 we completed our initial public  offering  on the  NASDAQ Global Market

issuing 9,000,000 ADSs at a price to the  public of $10.25 per ADS,  representing 900,000 of our
common shares. On September 30, 2015  the underwriters of our initial public  offering exercised in full
their over-allotment option to purchase  an additional 1,350,000 ADSs, representing 135,000 common
shares, at the initial public offering price  of $10.25  per  ADS, less  underwriting discounts. Including the
over-allotment ADSs we sold an aggregate of 10,350,000  ADSs representing 1,035,000 common  shares,
in our initial public offering, which resulted in gross proceeds  of approximately $106.1 million and net
proceeds to us of approximately $92.4 million,  after deducting underwriting discounts  and offering
expenses.

April 2015 Financing

In March 2015, we entered into an agreement with certain existing  and  new investors to issue  and

sell common shares with contractual preference rights under a shareholders agreement. We refer to this
transaction as our April 2015 financing.  In connection with  our April 2015 financing, we agreed to sell
common shares with contractual preference rights under  the shareholders agreement  in two tranches.
In April 2015, we closed the sale of the first  tranche of 730,162  common  shares, including the sale of
511,188 common shares at a price per  share of A82.35 ($87.71) for A42.1 million ($44.8 million) in cash
consideration and the sale of 218,974 common shares in exchange for certain contributions in kind
consisting of the conversion of outstanding convertible loans and silent partnership interests. We also
agreed to sell a second tranche of common shares with  contractual preference rights under the
shareholders agreement to these investors at their option for an  aggregate purchase price of
$70.0 million if we did not complete a  public  offering  in the  United States within specified parameters
or by a specified date. Upon the closing of our initial  public offering and  issuance  of the shares  for
nominal value in satisfaction of preferred  dividends, all contractual  preference rights under the
shareholders agreement terminated.

Critical Accounting Policies

Our management’s discussion and analysis of  our financial condition and  results  of operations  is

based on our financial statements, which we  have prepared in accordance with  generally  accepted
accounting principles in the United States,  or U.S.  GAAP. The preparation  of  our  financial statements
requires us to make estimates and assumptions that  affect the reported amounts  of  assets and liabilities
and the disclosure of contingent assets and liabilities at the end of the  reporting period,  as well as  the
reported revenues and expenses during  the reporting periods.  We base our estimates on  our limited
historical experience, known trends and  events 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
values of assets and liabilities that are  not  readily apparent  from  other sources. Actual  results may
differ  from these estimates under different assumptions  or conditions.

Our significant accounting policies are described in more detail in the notes  to  our  financial
statements appearing at the end of this filing.  However,  we  believe that  the  following  accounting
policies are the most critical to aid you in  fully understanding and evaluating our financial  condition
and results of operations.

Research Premium and Grant Revenue

Grant revenue comprises (1) the research  premium from  the Austrian  government, (2) grants
received from the Vienna Center for  Innovation and Technology  (Zentrum f¨ur Innovation, or ZIT) and
the Vienna Business Promotion Fund (Wiener Wirtschaftsf¨orderungsfonds, or WWFF) and (3) the benefit
of government loans at below-market interest rates.  Please refer to note  3 of our audited  consolidated
financial statements included elsewhere in  this Annual Report for  further  details on our grant revenue.

The research premium we received from the  Austrian  government was calculated as  10% of a

specified research and development cost  base  for the  years  ended December  31, 2015 and
December 31, 2014. For the year ended December 31, 2016, the research premium was calculated as
12% of a specified research and development cost base. We recognize the  research  premium, as  long as
we have incurred research and development expenses. The WWFF grant  is paid out through the
landlord in the form of a monthly reduction  in lease payments and is recognized over the period from
grant date in March 2010 until end of the lease termination waiver term in December  2017. The ZIT
grants are provided to support specific research projects and are recognized  according to the progress
of the respective project. All grants are non-refundable as  long as  the conditions of the grant  are met.
We  are and have been in full compliance with the conditions of  the grants and all related regulations.

The benefit of a government loan at a below-market rate of interest is treated as a government
grant. The benefit due to the difference between  the market rate of interest and  the rate  of interest
charged by the governmental organization  is  measured as the  difference between the  initial carrying
value of the loan and the proceeds received. This  benefit is  deferred,  and recognized through profit
and loss over the term of the corresponding liabilities.

Convertible Loans and Additional Call  Options

Between July 2011 and January 2015,  we  entered into five convertible loans with certain of our
shareholders. Under the loans, the lenders  had the  right to convert their  entire claim for repayment of
the loans into common shares with contractual preference rights under  a shareholders agreement.
Loans were payable in cash on the respective repayment  date if not previously converted. In
conjunction with the convertible loan  agreements we entered  into  in 2011 and 2012,  we also  granted
the lenders additional call options to  acquire  common shares with contractual preference rights  under
the shareholders agreement. No transaction costs were incurred  in conjunction with our entry  into  the
convertible loan agreements.

In connection with our April 2015 financing, all of the lenders  under  our convertible loan

agreements waived all rights and claims they had in connection with the convertible  loan agreements.
In particular, all call option rights as  well  as  claims on payments  of accrued interest were waived.  All
claims for repayment, excluding accrued interest,  under all  convertible loan agreements, were  converted
into common shares with contractual preference rights under  the shareholders agreement.  Any  accrued
interest, as well as the additional call option  rights were forfeited.

Prior to their conversion in April 2015, we presented  the convertible  loans as  a liability in the
consolidated balance sheet. We also evaluated the  requirement to bifurcate embedded options  within
the convertible loans in accordance with ASC 815, Derivatives and Hedging, or ASC 815. ASC 815
provides criteria that, if met, require companies  to  bifurcate conversion options from their host
instruments. These criteria include circumstances  in which (1) the economic characteristics and  risks  of
the embedded option are not clearly  and  closely related  to the economic characteristics and risks  of the
host contract, (2) the hybrid instrument  is not remeasured at fair  value  under otherwise  applicable
generally accepted accounting principles  with changes reported  in fair  value as  they occur, and  (3) a
separate instrument with the same terms  as the  embedded option  would be considered a derivative
instrument. Discounts associated with  convertible  loans were amortized over  the term of the  related
debt using the effective yield method.

We  also accounted for the additional  call options issued with the  convertible loans in 2011  and
2012 as well as our loan from Kreos Capital IV (UK) Limited, or Kreos, in July 2014, pursuant to
ASC 815, which provides a two-step model to be applied in determining  whether  a financial instrument
or an embedded feature is indexed to an issuer’s  own stock. Due to the circumstances that the
additional call options did not meet the ‘‘fixed for  fixed’’  criteria under ASC 815-40, Contracts in
Entity’s Own Equity, and did not meet the definition of a derivative, the  additional call options were
classified as a liability. The call options were  accounted for  at  fair value by use  of  an option  pricing
model, or OPM, at inception and in subsequent  periods, with changes in  fair value recognized  in the
other  income (expense), net line item within  the consolidated statement of comprehensive income
(loss).

Silent Partnership

In June 2014 and January 2015, we entered into silent  partnership agreements  with certain of our
shareholders, which entitled each of the silent  partners to a proportionate share  in the fair  value of the
company, similar to a shareholder, including a share in  profit or loss,  according to an agreed
participation rate, were classified as mezzanine equity pursuant  to  ASC 480, Distinguishing Liabilities

from Equity, and ASC 815. The silent partnership interests  were evaluated for equity or mezzanine
classification based upon the nature  of the silent partnership settlement provisions, which  provided us
the unilateral option to settle the obligation in cash  or a variable number of shares.  However, when a
settlement in shares cannot always be presumed, irrespective of probability of the event occurring,  a
classification outside of stockholders’ equity is  required. Mezzanine equity was initially measured at fair
value and subsequently at the redemption  value  at each reporting period,  which represented the
anticipated proceeds resulting from an  exit  event (trade sale  or an initial  public  offering). Such
amounts were recognized in retained earnings.

In connection with our April 2015 financing, all of the claims for  repayment of the silent
partnership interests, including interest  accrued thereon, converted  into common shares with
contractual preference rights under a shareholders  agreement.

April 2015 Financing

In March and April 2015, we entered  into  agreements with  our existing shareholders and certain

new investors to issue and sell common  shares with contractual preference rights under a  shareholders
agreement.

The April 2015 financing agreements  resulted  in the following effects with respect  to  our existing

financial instruments:

(cid:127) all existing convertible loan agreements and silent partnership  interests were  converted  to

common shares with contractual reference rights  under a  shareholders  agreement;

(cid:127) the lenders under our convertible loan agreements irrevocably waived their  claims for  payment

of interest accrued on the loan amounts;

(cid:127) the lenders under our convertible loan agreements irrevocably waived the call option rights

granted under our convertible loan agreements; and

(cid:127) the silent partners irrevocably agreed to the  forfeiture  of  their  claims for payment of  interest

accrued on their silent partnership investments.

Pursuant to our shareholders agreement,  signed on April 2,  2015, the holders  of  the shares  issued

in our April 2015 financing were granted  certain  preferential rights. These rights include the right  of
certain shareholders to acquire additional common  shares against payment  of  the nominal amount of
A1.00 per share following an appropriate resolution of all of  our shareholders, which we refer to as the
preferred dividend. The preferred dividend accrued at a rate per annum of 8%, based on the  number
of days that have elapsed from the issuance of  such shares until the occurrence of certain triggering
events, including an initial public offering, a  sale  of  the company, voluntary conversion to preference
shares by the shareholders, and a liquidation. The preferred dividend was cumulative and  perpetual,
and could be paid in cash or shares based  on a shareholders vote.  Upon  the closing of our initial public
offering and the issuance of the shares for  nominal value  in satisfaction of the  preferred dividends, all
contractual preference rights terminated  in December 2015.

The shares from the April 2015 financing were recorded upon registration of the  capital increase

in the Austrian commercial register in  May 2015.  As a result of the  preferred dividend  rights, which
were not legally separable, we were deemed to have  issued common shares  accompanied by preferred
dividends that may be settled for cash or  shares. Accordingly, the  proceeds from  the April 2015
financing, including the consideration from conversion of the convertible loan agreements  and silent
partnership interests, were recorded  as  mezzanine  equity. A mezzanine equity  classification arises as a
result of the dividend provision in our  shareholders agreement, under which  our then-current
shareholders covenanted to vote in favor of  the requisite shareholder resolutions to allow us to satisfy
the preferred dividend rights. As a result, (1)  we could not avoid  fulfilling  the preferred dividend rights

if a triggering event occurred that was outside our control, and  (2) we could not always  presume a
settlement in shares. Therefore, when  a  settlement in shares cannot always be presumed for an event
not solely within the control of the issuer, irrespective of probability of the event  occurring, a
classification outside of stockholders’ equity is  required. Mezzanine equity was initially measured at fair
value and subsequently at the redemption  value  at each reporting period,  which represented the
anticipated proceeds resulting from an  exit  event (trade sale  or an initial  public  offering). Such
amounts were recognized in retained earnings.

The April 2015 financing and the related conversion of our outstanding convertible loan

agreements and silent partnership interests  resulted in total consideration to us of $77.3  million which
was recorded in mezzanine equity. Upon the closing of our initial public  offering in  September 2015, a
triggering event occurred as described  above, and the  holders of the preferred dividend right  received
17,149 additional shares against payment  of  the nominal amount of A1.00 per share, effectively
removing the mezzanine equity classification.

Stock Option Plan 2007

Our shareholders adopted our Stock Option Plan 2007 on September 12, 2007  and subsequently

approved amendments to the Stock Option Plan 2007 on September, 17,  2009, May  9, 2010 and
June 30, 2015. References to our Stock Option Plan 2007 in  this  Annual Report refer to the plan as
amended. No additional awards will  be  granted under  the Stock Option Plan 2007. All employees
(including members of the management  board),  selected  members of the supervisory board and  further
participants were eligible to participate  in the  Stock Option  Plan  2007. Options  granted under  the
Stock Option Plan 2007 give beneficiaries  the right to acquire our shares. Options granted  under the
Stock Option Plan 2007 generally vest  over four years from the date of participation. Typically,  25% of
the options subject to a particular grant  vest on  the last day of the last  calendar  month of the  first  year
of the vesting period, a further 25%  of the  options  vests on the last day of the  last calendar month  of
the second year of the vesting period, and  the remaining 50% vests on a  monthly pro-rata basis over
the third and fourth years of the vesting  period  (i.e., 2.083% per month). However,  alternative vesting
schedules applied for beneficiaries who had worked for us prior to the  date of the  adoption  of our
Stock Option Plan 2007. All options granted under such  alternative  vesting  schedules  have fully  vested.

The Stock Option Plan 2007 provides  that 50% of any then-unvested options shall automatically

vest upon a liquidity event, which refers to an exclusive license of or the sale  or other disposal  of  50%
or more of our assets, a sale or other disposal (but not a pledge) of  50%  or more of our shares, a
merger of ours with any third party, or a  consolidation,  liquidation, winding up  or other form of
dissolution). If a beneficiary has an unjustified termination or a justified  premature termination (as
such terms are used in the Stock Option Plan 2007) within one  year of  the liquidity event, all remaining
unvested options held by the beneficiary shall automatically vest in full.

Unless otherwise specifically permitted in an  option agreement or resolved upon by the
management board with the approval  of the  supervisory board, the exercise  of vested  options  is
permitted under the Stock Option Plan  2007 only during specified periods and on  specified terms  in
the case of a  liquidity event or following an initial public offering of  our shares occurring during the
term of the option, regardless of whether or not the beneficiary is  then  providing services  to  us.  A
beneficiary is entitled to exercise vested options at  any time during the remaining term  of the option.
No options may be exercised under the Stock Option Plan 2007 after September 27,  2017. Any options
not exercised by September 27, 2017 automatically terminate  and are forfeited.

Beneficiaries are not entitled to transfer vested options,  except to individuals  by  way of inheritance

or bequest. Options do not entitle beneficiaries to exercise any  shareholder rights.  Beneficiaries may
exercise shareholder rights only with respect  to  any shares they hold.

Stock Option Plan 2015

Our shareholders, management board and  supervisory board adopted our Stock Option Plan 2015
on April 2, 2015 and our shareholders approved an  amended and restated version  of the Stock  Option
Plan 2015 on June 30, 2015. An amendment to the amended  and restated Stock Option Plan  2015 was
approved by our shareholders on July 22,  2015. References to our  Stock Option  Plan 2015 in this
Annual Report refer to the amended  and  restated version  of  the Stock  Option Plan 2015, as amended.
The Stock Option Plan 2015 became effective  on July 3, 2015 upon the  registration with the
commercial register in Austria of our  conditional capital  increase approved  by  our  shareholders on
June 30, 2015. The Stock Option Plan 2015 initially  provided  for the  grant of options for  up to 95,000
common shares to our employees, including members of our management  board, and to members of
our  supervisory board. Following approval by our shareholders  at our 2016 annual general  meeting, the
number of shares available for issuance under the Stock  Option Plan 2015 was  increased to 346,235
common shares. Grants of stock options  for 201,568  common  shares  under this plan to members  of the
management board, selected members  of  the  supervisory board and  certain employees  were made as of
December 31, 2016. Options granted  under  the Stock Option Plan 2015 generally have  a term of
10 years and vest over four years. Typically 25%  of  the options  subject to a  particular  grant vest on the
last day of the of the last calendar month  of  the first year of the  vesting period, and the remaining 75%
vests on a monthly pro-rata basis over  the  second, third and  fourth years of the vesting period
(i.e., 2.083% per month). Any alternative  vesting  period determined by us  is subject to approval by our
management board, supervisory board or  shareholders, in  accordance with applicable voting
requirements.

The Stock Option Plan 2015 provides  that, if  a liquidity event (as  defined below) occurs,  all
options outstanding under the Stock  Option Plan 2015 will  be  assumed (or substantially equivalent
awards will be substituted by an acquiring or succeeding corporation (or an affiliate of the  acquiring or
succeeding corporation)), and any then-unvested options shall continue to vest in accordance with the
beneficiary’s original vesting schedule. If a  beneficiary is terminated due to a  good leaver event (within
the meaning of the Stock Option Plan  2015),  on or  prior to the first anniversary  of  the date  of  the
liquidity event, the beneficiary’s options  will  be  immediately exercisable in full  as of the date of such
termination. If the acquiring or succeeding corporation  (or  an affiliate of the  acquiring or  succeeding
corporation) refuses to assume the options  outstanding under  the Stock Option Plan 2015 or to
substitute substantially equivalent options therefore, all then-unvested options under  the Stock Option
Plan 2015 will automatically vest in full  upon the liquidity event.  For purposes  of  the Stock Option Plan
2015, a liquidity event generally refers  to  an  exclusive  license of or the sale, lease or other disposal of
all or substantially all of our assets, a sale  or other disposal  (but  not a pledge) of 50%  or more of our
shares, a merger or consolidation of  us with or  into  any third party,  or  our  liquidation,  winding up  or
other form of dissolution of us.

Unless otherwise specifically permitted in an  option agreement or resolved upon by the
management board with the approval  of the  supervisory board, the exercise  of vested  options  is
permitted under the Stock Option Plan  2015 only during specified periods and on  specified terms  in
the case of a  liquidity event or following an initial public offering occurring  during  the term of the
option. A beneficiary is entitled to exercise  vested options at any time during the  remaining term of the
option while the beneficiary is providing  services to us, and within  the three-month period following  a
termination of the beneficiary’s services due to a good leaver  event. Options granted under  the Stock
Option Plan 2015 will have a term of  no  more than ten years from the beneficiary’s  date of
participation.

Beneficiaries of options granted under the Stock Option Plan 2015  are not entitled  to  transfer

vested options, except to individuals by way of inheritance or bequest. Options do  not  entitle
beneficiaries to exercise any shareholder  rights. Beneficiaries  may exercise shareholder rights  only  with
respect to any shares they hold.

We  measure the options under our equity incentive plans at fair  value at their grant  date in
accordance with ASC 718, Compensation—Stock Compensation,’’ using the Black-Scholes model. All
options under the Stock Option Plan 2007  have an  exercise  price of A6.72 ($7.32) per share and a
maturity of September 27, 2017. The fair value of such share-based  compensation is recognized as  an
expense over the respective vesting period. Share-based compensation  expense under the Stock  Option
Plan 2007 was $96,000, $78,000 and $95,000 for the years ended December 31, 2014, 2015 and 2016,
respectively. No options were granted  under  the Stock Option Plan 2007 during 2015 or 2016. The
weighted average fair value of the 1,088 options granted  in 2014 was $209.11 per share. Options
granted during the year ended December 31,  2016 under  the Stock Option Plan 2015 have a  weighted-
average exercise price of  A71.64 ($80.24) and a weighted average fair  value of A27.31 ($30.58). We
recognized stock-based compensation expense of approximately $2.5  million during the  year ending
December 31, 2016 related to the options granted under the Stock  Option Plan 2015.

We  account for related social security contributions  as liabilities which are recognized on  the date

of the event triggering the measurement and payment of the  tax to the taxing  authority; or the date the
options are exercised.

We  expect to grant additional stock options  that will result in  additional  share-based  compensation
expense. Following the consummation of our initial public offering, we determined stock  option values
based on the market price of our common shares.

Fair Value Estimation

We  use valuation techniques that include  inputs  that are not based on observable market data to

estimate the fair value of certain types  of  financial instruments, including stock options under our
equity incentive plans.

Valuation of Total Equity and Certain Financial Instruments prior to our Initial Public Offering

Prior to our initial public offering, the fair value  of the total  equity was determined by
management and took into account the  most recently available valuation of  the company and the
assessment of additional objective and  subjective factors we believed  were relevant. We considered
numerous objective and subjective factors  to determine the best estimate of the fair value  of  the equity
and certain financial instruments that represented  potential interests in the equity,  including the
following:

(cid:127) the progress of the research and development  programs;

(cid:127) achievement of enterprise milestones, including the entering  into  collaboration and  licensing

agreements;

(cid:127) contemporaneous third-party valuations of the  common shares;

(cid:127) the forecasted performance and operating results;

(cid:127) the estimated costs of capital to fund operations;

(cid:127) the rights and preferences of the financial instruments,  e.g. liquidation preference of  common
shares with contractual preference rights relative to other common shares,  conversion  rights of
the convertible loan agreements, etc.;

(cid:127) the likelihood of achieving a discrete liquidity event, such  as a  sale of the  company or an initial

public offering given prevailing market conditions; and

(cid:127) external market and economic conditions impacting  the industry sector.

In determining the fair values of the  equity, we considered three generally  accepted approaches:

the income approach, market approach and cost approach.  Based on the  stage of development and
information available, we determined  that the income approach was the most appropriate method.

Discounted cash flow, or DCF, a form of the income approach,  is an estimate of the present value
of the future monetary benefits expected  to flow to the owners of a business. It  requires a projection of
the cash  flows that the business is expected to generate. These cash flows are converted to present
value by  means of discounting, using  a  rate of return that accounts for the time  value of  money  and the
appropriate degree of risks inherent in  the business. The discount rate in  the DCF analysis was based
upon a weighted average cost of capital, or WACC.  The  WACC was derived by using the Capital Asset
Pricing Model and inputs such as the  risk-free rate, beta  coefficient, equity risk  premiums and the size
of the company.

After determining the fair value of total  equity for each valuation date,  the option  pricing  method,
or OPM, was used to estimate the fair value  for  all financial instruments  that represented claims  on the
company’s assets, including the different  share classes as well as the following instruments:

(cid:127) options under the Stock Option Plan 2007 and Stock Option  Plan  2015;

(cid:127) the investment from the silent partnership;

(cid:127) options related to our loan from Kreos, and

(cid:127) options and conversion rights related  to  the convertible loans agreements.

Under this approach, each class of securities  was  modeled  as a combination of  call options with a

unique  claim on the assets of the company. The characteristics of each  security’s class defined these
claims. This reflected differences in value  allocation at  different  company value  levels that result from
differences in security classes, for example from  liquidation  preference  rights, dividend accrual, etc.  The
OPM used the Black-Scholes option-pricing  model to price the call options. This model defines  the
securities’ fair values as functions of  the  current fair value of the  company and uses  assumptions such
as the anticipated timing of a potential  liquidity event and the  estimated  volatility  of  the entire equity.
Volatility was estimated based on the observed daily share price returns of peer companies over a
historic period closely matching the period for  which expected volatility is estimated.  Volatility is
defined as the annualized standard deviation of share price returns. In  the allocation of equity, the
company also considered valuation outcomes through  a sale of the company compared to an initial
public offering, and considered the probabilities of each at each valuation date, since the treatment of
the liquidation rights were different for  these two  events. The aggregate value per security class  was
then divided by the number of securities  outstanding to arrive at the value  per  security.

Our valuations relied on DCF models  to  derive the total enterprise value. The cash flow

projections were based on probability-weighted scenarios which  considered estimates of time to market,
market share and pricing of lefamulin  in  the target indications.  The cash flow  projections were
estimated over a period equal to the  expected patent life,  and a  terminal value  period was not applied.
The expected sales were estimated using  a  detailed market model that  comprises historical and
expected number of therapies as well as  prices  of relevant  drugs  per  indication  and region, based  on
market reports, surveys and estimates  by  management. Production and research and  development costs
were estimated at the indication level  with  general and administrative costs  and selling and marketing
costs estimated at the overall company  level. A  WACC of  16.0%  was applied for each valuation date.
The OPM relied on the anticipated timing and probability  of a liquidity event  based on  then current
plans and estimates of the management as per each valuation date. As of July  4, 2014 and
December 31, 2014 the probability of an initial public offering was estimated at  60% (2013 and earlier:
10%) and of a sale at 40% (2013 and  earlier:  90%).  As of December 31, 2014 the estimated volatility
was 65% (2013: 80%) based on historical  trading  volatility for the publicly traded  peer companies  and a

time to liquidity of 0.5 years for the initial public  offering  scenario and 2.5 years for the trade sales
scenario (2013: 1.2 years and 4.4 years, respectively).

In the course of the April 2015 financing the  investment from the silent  partnership as  well as the
convertible loans were converted to common shares with contractual  preference rights and  the lenders
under the convertible loan agreements irrevocably  waived and acknowledged the  termination  of  their
call option rights granted thereunder. The options related to our  loan from  Kreos  were exercised in
May 2015. Hence, only the options under  the Stock Option Plan 2007 and Stock  Option Plan 2015
remained as instruments that required the  determination  of a fair value.

Valuation of Stock Options Following  our  Initial Public Offering

Upon the closing of our initial public  offering, the  preference rights  of  certain  common shares

terminated and the fair market value for  all shares equals the market price per share.  In  accordance
with ASC 718, Compensation—Stock Compensation, the grant date fair value of stock options is
determined based on the price of the  American Depositary Shares on the date  of grant by use  of a
Black Scholes model.

Research and Development Expenses

Research expenses are defined as costs  incurred for current or planned  investigations undertaken

with the prospect of gaining new scientific or technical knowledge  and  understanding. Development
expenses are defined as costs incurred  for  the application of research  findings or  specialist  knowledge
to production, production methods, services or goods prior to the  commencement of commercial
production or use. We expense all research  and  development costs as  incurred.

The following costs, in particular by their nature, constitute research and development expenses:

the appropriate proportions of direct personnel  and material costs, related  overhead for  internal or
external  technology, engineering and other departments that provide services; costs  for experimental
and pilot facilities (including depreciation  of buildings  or parts of buildings  used for  research  or
development purposes); costs for clinical research;  regular costs  for  the utilization of third parties’
patents for research and development  purposes; other taxes related to research facilities; and fees for
the filing and registration of self-generated patents that are not capitalized.

Our projects are currently in the research  and development  phase and  marketing  approval by U.S.,

European and other foreign regulatory  authorities is not, nor will  be,  available  for any product  in the
near future.

Taxes

We  are subject to income tax in Austria and the United  States.  Significant  judgments  and estimates
are required in determining the consolidated income tax  expense, including a determination of whether
and how  much of a tax benefit taken by  us in  our tax filings  or  positions is more likely than  not  to  be
realized. Changes in tax laws and rates could  also affect recorded deferred tax  assets and liabilities in
the future. We are not aware of any such changes that would be expected to have  a material effect on
our  results of operations, cash flows  or financial  position. There are many transactions and  calculations
for which the ultimate tax determination  is uncertain. Where the  final  tax outcome of  these matters is
different from the amounts that were initially recorded, such differences will impact the  current and
deferred income tax assets and liabilities in  the period in which  such determination is made.

Our U.S. subsidiary is subject to income  taxes due to the fact that it provides to us certain
management and other services related to research and development activities. These  services  are
rendered on terms that were negotiated at arm’s length pursuant to a  services agreement  with us.

Deferred tax assets have only been recognized to the extent  that we believe  those assets are more

likely than not to be realized. In making such a determination we  consider  all  available positive and
negative evidence, including future reversals of existing taxable  temporary differences, projected future
taxable income, tax-planning strategies, and results of recent operations. If we determined that we
would be able to realize our deferred  tax  assets in the  future in  excess  of their  net recorded amount,
we would make an adjustment to the deferred tax asset valuation allowance, which  would reduce the
provision  for income taxes. As of December 31,  2016, we had cumulative  net operating loss
carryforwards in respect of losses of $216.9 million. The tax loss carry-forwards will not expire in
Austria.

Change in Functional Currency

We  have significantly expanded our presence  and operations in  the United  States,  and have  begun
to, and will continue to, incur a majority of the expenses for our clinical trials in U.S. dollars.  Also, the
majority of the funds raised from our  initial public offering in September 2015  and our rights  offering
and the related underwritten offering  in December  2016, as well as other financing  activities, are
currently invested, and are expected to  remain invested, in U.S. dollar  denominated instruments to
fund our U.S. operations. As a result, as  of January 1, 2016,  we determined that our functional  and
reporting currency had changed from  euro to the U.S. dollar.

The change in functional currency is accounted  for prospectively from January 1,  2016 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. However, the change in  reporting currency represents an
accounting policy change, and accordingly,  the change has been applied retrospectively. Therefore,
financial information included in our  audited consolidated financial statements  for the  years  ended
December 31, 2014 and 2015 previously  reported in  euro has  been restated into the  new reporting
currency U.S. dollars.

For periods prior to January 1, 2016,  the effects of exchange  rate  fluctuations on  translating

foreign currency monetary assets and liabilities into U.S. 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
yearly exchange rates prevailing for the  relevant 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 euro 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). The differences  between  items of equity translated at historical
exchange rates as of December 31, 2015  and their value as of  January 1, 2016 translated at the
exchange rate as of December 31, 2015 are shown  in the line item ‘‘Change in functional  currency’’
within the condensed consolidated statement  of  changes in  stockholders’ equity.

For periods commencing on and after January 1, 2016, 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,  2016
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

Implications of Being an Emerging Growth Company

As a company with less than $1 billion in revenue during our last fiscal year,  we qualify as an

‘‘emerging growth company’’ as defined  in  the Jumpstart Our  Business Startups Act of  2012, or the
JOBS  Act. An emerging growth company  may take advantage  of  specified reduced reporting and other
burdens that are otherwise applicable  generally  to  public companies. These  provisions include:

(cid:127) an exemption from compliance with  the auditor  attestation requirement  of Section 404  of  the

Sarbanes-Oxley Act of 2002 on the design and effectiveness of our internal controls over
financial reporting;

(cid:127) an exemption from compliance with  any requirement that the Public  Company Accounting

Oversight Board may adopt regarding mandatory audit firm rotation or a supplement to the
auditor’s report providing additional information about  the audit and the financial statements;

(cid:127) reduced disclosure about the company’s executive compensation arrangements; and

(cid:127) exemptions from the requirements to obtain a  non-binding  advisory vote on executive

compensation or a shareholder approval of any golden  parachute arrangements.

We  may take advantage of these provisions until December 31,  2020 or such earlier time  that  we

are no longer an emerging growth company. We  would cease to be an emerging  growth company upon
the earlier to occur of: the last day of the fiscal year  in which  we have  more than  $1 billion in annual
revenues; the date we qualify as a ‘‘large  accelerated filer,’’ with  at  least more  than $700  million  in
market value  of our share capital held  by  nonaffiliates; or  the issuance by us of more  than $1  billion of
non-convertible debt over a three-year  period. We  may choose to take advantage  of  some, but not all,
of the available benefits under the JOBS Act.  We  have taken advantage of some reduced reporting
burdens in this Annual Report. Accordingly, the  information contained herein may be different than
the information you receive from other  public  companies in which you hold stock.

In addition, the JOBS Act provides that an emerging growth company can take  advantage  of  an

extended transition period for complying with new or revised  accounting standards. This provision
allows an emerging growth company to delay the adoption of some accounting  standards until those
standards would otherwise apply to private companies.  We have irrevocably  elected  not  to  avail
ourselves  of delayed adoption of new or  revised accounting  standards and, therefore, we  will  adopt new
or revised accounting standards on the  relevant  dates on which  adoption  of such standards  is required
by for non-emerging growth companies.

Revenues

Revenues, consisting primarily of research premium and grant revenue, increased  by  $2.7 million

from $3.8 million from the year ended  December 31, 2015  to  $6.5 million for  the year  ended
December 31, 2016. The change was primarily  due  to  a $2.6 million increase in anticipated  grant
revenue from research premiums provided to us by the Austrian  government as  a result of  increases in
our  applicable research and development expenses.

Research and Development Expenses

Research and development expenses increased by $24.4 million from $23.6 million for  the year
ended December 31, 2015 to $48.0 million  for  the year  ended December  31, 2016.  The  increase was
primarily due to higher costs related  to  our Phase 3 clinical trials of lefamulin.  Research materials and
purchased services for our other programs and initiatives were relatively limited during both periods.
Staff costs related  to research and development increased for the year ended  December 31,  2016
compared to the year ended December 31,  2015, primarily due to the addition of employees and
increased clinical development costs.

General and Administrative Expenses

General and administrative expense increased by $5.6  million  from  $7.9 million for the year ended
December 31, 2015 to $13.5 million for  the  year  ended December 31, 2016. The increase was primarily
due to increased staff costs related to the hiring of additional  employees and increased professional
service fees related to operating as a public company.

Other income (expense), net

Other income (expense), net decreased  by  $3.2 million  to  a $0.8  million loss during the year ended
December 31, 2016 compared to the same period in 2015.  The change was primarily due to an increase
in losses from the re-measurement of  foreign currency balances as a result of  the change in our
functional currency.

Interest expense, net

During  the year ended December 31,  2016,  net interest  expenses decreased by $22.3  million
compared to the same period in 2015  primarily due to the decrease  in the effective interest accrued
under the convertible loan agreements, which  were converted into  equity securities in connection with
our  April 2015 financing, and the decrease in  interest expense on  the Kreos loan, which was fully
repaid in November 2015.

Revenues

Revenues, consisting primarily of research premium and grant revenue, increased  by  $1.4 million

from $2.4 million for the year ended  December 31,  2014 to $3.8 million for the year ended
December 31, 2015. The increase was primarily  due  to  a $2.2  million increase  in anticipated  research
premiums as a result of a higher applicable research  and development  cost base, offset by a
$0.8 million decrease in grant revenue  in  the year ended  December 31,  2015.

Research and Development Expenses

Research and development expenses increased by $14.2 million from $9.4 million for  the year

ended December 31, 2014 to $23.6 million  for  the year  ended December  31, 2015.  The  increase was
primarily due to higher costs related  to  preparation for our Phase 3 clinical  trials of lefamulin and a
$1.1 million increase in staff costs for the year ended  December 31,  2015 compared to year  ended
December 31, 2014 primarily due to the  addition of employees during 2015.

General and Administrative Expenses

General and administrative expenses  increased by $4.2  million  from  $3.7 million for the year ended

December 31, 2014 to $7.9 million for the  year  ended December 31, 2015. The increase was primarily
due to a $2.2 million increase in professional service fees related  to  preparing for  a potential offering
and operating as a public company, and  a $2.0 million increase in staff costs related to additional
employees, which includes higher stock-based  compensation  expense of approximately $0.6  million
related to the options granted under the  Stock Option  Plan  2015.

Other income (expense), net

Other income (expense), net increased  by $2.9 million to $2.4 million during the year ended

December 31, 2015 compared to the same period in 2014.  The change was primarily due to higher
gains from the re-measurement of foreign  currency  balances.

Interest expense, net

During  the year ended December 31,  2015,  interest expense, net increased by $19.2  million
compared to the year ended December 31,  2014, primarily due to a $20.5  million increase of effective
interest accrued under the convertible  loan  agreements, which  was  largely  due  to  the contingent
beneficial conversion feature recognized  as part of the April 2015 financing. The increase  in interest
expense was partially offset by the prepayment of  the $6.6 million loan  from Kreos in November 2015
that included payment of discounted future interest on the loan.

Liquidity and Capital Resources

Since our inception, we have incurred net  losses and generated negative cash flows from our
operations. To date, we have financed  our operations through the sale of equity securities, including
our  initial public offering of ADSs and  private placements of our common shares, convertible debt
financings and research and development support from  governmental grants  and loans. As of
December 31, 2016, we had cash and  cash equivalents and  short term investments of $83.9 million.

On December 19, 2016, we completed a rights offering  and  a  related  underwritten  offering for the
sale of an aggregate of 588,127 common shares resulting in  aggregate  gross proceeds of approximately
$24.8 million and net proceeds to us  of approximately  $20.6 million, after deducting  underwriting fees
and offering expenses.

On September 23, 2015 we completed our initial public  offering  on the  NASDAQ Global Market

issuing 9,000,000 ADSs at a price to the  public of $10.25 per ADS,  representing 900,000 of our
common shares. Each ADS represents  one tenth of a common share.  On September  30, 2015 the
underwriters of our initial public offering exercised  in full their over-allotment option to purchase an
additional 1,350,000 ADSs, representing  135,000 common  shares, at the initial  public  offering price  of
$10.25 per ADS, less underwriting discounts. Including the  over-allotment ADSs, we sold  an aggregate
of 10,350,000 ADSs representing 1,035,000 common shares,  in our initial  public  offering, which resulted
in gross proceeds of approximately $106.1  million and net  proceeds to us of approximately
$92.4 million, after deducting underwriting discounts  and offering expenses.

In connection with our April 2015 financing, we sold 730,162 common shares with contractual

preference rights under a shareholders  agreement, including  the sale  of  511,188 common  shares at a
price per share of A82.35 ($87.71) for A42.1 million ($44.8 million) in cash consideration and the  sale of
218,974 common shares in exchange for  certain contributions  in-kind consisting of the conversion of
outstanding convertible loans and silent  partnership  interests. We also agreed to sell a second  tranche
of common shares with contractual preference  rights under the shareholders  agreement to the investors
in our April 2015 financing at their option  for an aggregate purchase price  of  $70.0 million if we did
not complete a public offering in the  United States within specified parameters or by a  specified date.
Upon the closing of our initial public  offering and the  issuance  of the shares  for nominal value in
satisfaction of the preferred dividend  rights, all contractual preference  rights under the shareholders
agreement terminated.

Between 2011 and 2015 we entered into five convertible loan agreements with certain of  our
shareholders for proceeds in the aggregate  amount  of  $18.2 million. All outstanding  convertible loans
converted into common shares with contractual  preference  rights under the shareholders  agreement in
connection with our April 2015 financing.

We  entered into silent partnership agreements with certain of our  shareholders for aggregate

proceeds of $0.5 million in the second  quarter of 2014 and $0.9  million in  the first quarter of 2015.
These agreements have terminated and the related claims  for  repayment were converted into common
shares with contractual preference rights under the  shareholders agreement in  connection with  our
April 2015 financing.

Also during the second quarter of 2014,  we entered  into  a A5.0 million ($6.6 million) loan

agreement with Kreos that resulted in  net proceeds of $6.2 million after deduction  of the initial  interest
and principal payments and transaction costs at  closing. In connection with the  loan agreement, we
granted Kreos Capital IV (Expert Fund)  Limited a warrant to purchase our common shares with
contractual preference rights under the shareholders  agreement, which  Kreos Capital IV (Expert  Fund)
Limited has exercised in full. As collateral for the loan,  we  pledged our  intellectual  property, fixed
assets exceeding a book value of  A1,000, the receivables related to the research premium and our bank
accounts. In July 2015, Kreos Capital IV  (UK)  Limited  agreed to release us  from the pledge of our
intellectual property upon the closing of our  initial public offering. We prepaid the Kreos loan  in
accordance with the terms of the loan  agreement  in November 2015.

ended December 31, 2015 to $49.3 million for the year ended December  31, 2016  primarily due to a
$28.4 million increase in net loss, after adjustments  for non-cash amounts included in net income
partially offset by improved working  capital  of  $1.0 million primarily from  higher trade payables and
other liabilities.

Investing Activities

Cash flow from investing activities changed  by $100.1 million from $76.7 million cash  outflow  in
the year ended December 31, 2015 to  $23.4  million cash inflow  in the year ended December 31,  2016
primarily due to the redemption of term deposits. Other  investing activities  were relatively insignificant
in both periods and related primarily  to  the acquisition of equipment in support  of  our  research  and
development activities.

Financing Activities

Cash flow generated from financing activities decreased by $110.7 million from $133.0 million for

our  initial public offering in September  2015, $3.4 million from the issuance of an additional
convertible loan in January 2015 and proceeds of $0.9 million  from a silent partnership agreement
entered into in January 2015. The year over  year  decrease in financing cash  inflows was  partially offset
by proceeds of $24.8 million from our  December 2016 rights offering,  a $7.4 million decrease  of  cash
outflows for repayments of long-term borrowings and a $12.1  million  decrease in equity  transaction

Operating Activities

Cash flow utilized by operating activities  increased  by $10.5 million from  $11.4 million for  the year

ended December 31, 2014 to $21.9 million for the year ended December  31, 2015  due  to  a higher net
loss of $13.1 million during the year ended December  31, 2015, after adjustments  for non-cash amounts
included in net income, partly offset  by  improved working capital of $2.6 million primarily from higher
accounts payable and accrued expenses.

Investing Activities

Cash flow utilized by investing activities increased by $76.6  million  from $0.1 million in  the year

ended December 31, 2014 to $76.7 million in  the year  ended  December  31, 2015 due to the purchases
of marketable securities and investments in term deposits. Other investing activities  were relatively
insignificant in both years and related primarily  to  the acquisition  of equipment in support of our
research and development activities.

Financing Activities

Cash flow generated from financing activities increased by $123.9 million from $9.1  million for the
year ended December 31, 2014 to $133.0  million for the year ended December  31, 2015 primarily due
to gross proceeds of $106.1 million from  our initial public offering in September  2015, cash proceeds  of
$44.8 million from our April 2015 financing, $3.4 million from  the issuance of an  additional convertible
loan in January 2015 and proceeds of $0.9  million  from a new  silent  partnership agreement in January
2015, compared with net proceeds from  our  loan from  Kreos of $6.2 million, additional convertible
loans in the aggregate principle amount of  $4.7 million  and proceeds of $0.5 million from a  new silent
partnership agreement in the year ended December  31, 2014. The year over year increase  was  partially
offset by equity transaction costs of $14.9  million  and a  $5.1  million increase of cash  outflows for
repayments of long-term borrowings, including $5.4 million from the prepayment of the Kreos loan in
2015.

Operating and Capital Expenditure Requirements

We  anticipate that our expenses will increase substantially as we continue the development  of and
potentially seek marketing approval for  lefamulin  and,  possibly, other  product candidates  and continue
our  research activities. Our expenses  will  increase if we suffer any delays  in  our  Phase 3  clinical
program for lefamulin for the treatment  of CABP, including  delays in  enrollment  of  patients. If we
obtain marketing approval for lefamulin  or  any other  product candidate that  we develop, we expect  to
incur significant commercialization expenses  related to product sales, marketing,  distribution and
manufacturing. Furthermore, we expect to  incur additional costs associated with operating as a public
company.

In addition, our expenses will increase if and as we:

(cid:127) initiate or continue the research and development  of  lefamulin for additional indications and of

our  other product candidates;

(cid:127) seek to discover and develop additional product candidates;

(cid:127) seek marketing approval for any product candidates that successfully complete clinical

development;

(cid:127) ultimately establish a sales, marketing and distribution infrastructure and  build up  inventory of
finished product and its components to commercialize any product candidates for which  we
receive marketing approval;

(cid:127) in-license or acquire other products,  product candidates  or technologies;

(cid:127) maintain, expand and protect our intellectual property  portfolio;

(cid:127) expand our physical presence in the United States; and

(cid:127) add operational, financial and management information  systems and personnel, including

personnel to support our product development,  our  operations  as a public company and our
planned future commercialization efforts.

We  expect that our existing cash, cash equivalents and short-term  investments will be sufficient  to
enable us to fund our operating expenses  and capital expenditure requirements  at least into the  second
quarter of 2018 and to obtain top-line  data  for both our  Phase 3 clinical trials of lefamulin. We have
based this estimate on assumptions that may prove to be wrong, and we could use our capital  resources
sooner than we currently expect. This estimate assumes, among other things, that we do not obtain any
additional funding through grants and clinical  trial support, collaboration  agreements or debt
financings.

Our future capital requirements will depend on many  factors, including:

(cid:127) the progress, costs and results of our Phase  3 clinical trials for lefamulin;

(cid:127) the costs and timing of process development and  manufacturing scale-up activities associated

with lefamulin;

(cid:127) the costs, timing and outcome of regulatory  review of lefamulin;

(cid:127) the costs of commercialization activities  for  lefamulin if  we receive, or expect to receive,

marketing approval, including the costs  and timing  of  establishing product  sales,  marketing,
distribution and outsourced manufacturing capabilities, including the costs of building  finished
product inventory and its components in  preparation of  initial marketing of lefamulin;

(cid:127) subject to receipt of marketing approval, revenue received from commercial sales of lefamulin;

(cid:127) the costs of developing lefamulin for  the treatment  of  additional  indications;

(cid:127) our ability to establish collaborations on favorable terms, if at all;

(cid:127) the scope, progress, results and costs of product  development of any  other product  candidates

that we may develop;

(cid:127) the extent to which we in-license or acquire  rights to other products, product  candidates or

technologies;

(cid:127) the costs of preparing, filing and prosecuting patent applications, maintaining and protecting our

intellectual property rights and defending  against intellectual property-related claims;

(cid:127) the continued availability of Austrian governmental grants;

(cid:127) the rate of the expansion of our physical  presence in  the United  States; and

(cid:127) the costs of operating as a public company in  the United  States.

Conducting clinical trials is a time-consuming,  expensive and uncertain  process that takes years to

complete, and we may never generate the  necessary data or results required to obtain marketing
approval and achieve product sales. Our  commercial revenues, if any, will be derived from  sales  of
lefamulin or any other products that we  successfully develop, none of which we expect  to  be
commercially available for several years,  if at all. In addition, if  approved,  lefamulin  or any  other
product  candidate that we develop, in-license  or acquire  may  not  achieve commercial success.
Accordingly, we will need to obtain substantial additional  financing to achieve our business objectives.
Adequate additional financing may not be available to us on acceptable terms, or at all. In addition, we
may seek additional capital due to favorable  market  conditions  or strategic considerations, even if we
believe that we have sufficient funds  for our  current or  future operating plans.

Until such time, if ever, as we can generate  substantial product revenues, we expect to finance our
cash needs through a combination of equity  offerings,  debt  financings, collaborations, and funding from
local and international government entities and non-government organizations in the disease areas
addressed by our product candidates and  marketing, distribution or licensing arrangements. To  the
extent that we raise additional capital  through the  sale of equity  or convertible  debt  securities, your
ownership interest will be diluted, and  the terms  of these  securities may include liquidation  or other
preferences that adversely affect your rights as a  security holder. Debt  financing, if available, may
involve agreements that include covenants limiting or restricting our ability to take  specific actions, such
as incurring additional debt, making capital expenditures or declaring dividends.

If we  raise additional funds through collaborations, strategic  alliances or marketing,  distribution or
licensing arrangements with third parties,  we may have to relinquish  valuable rights to our  technologies,
future revenue streams, research programs  or product candidates or to 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.

Operating lease obligations include rental agreements  for our  facilities in Austria and  the United

States.

Other contractual commitments relate  to  contracts  entered into with  contract research

organizations and contract manufacturing  organizations in  connection with the conduct of clinical trials
and other research and development  activities. Some of  these  commitments include early termination
clauses exercisable at our discretion. The amounts shown above  are estimated based  on the
assumptions that all remaining services  will  be  performed as agreed and all milestones  and other
conditions of the respective contracts are met.

Capital Expenditures

Our total purchases related to capital  expenditures were $216,000  and $603,000  for the  years

ended December 31, 2015 and 2016, respectively. We made no  significant investments in intangible
assets during  the years ended December  31, 2015 and 2016. Currently, there are no material capital
projects planned in 2017. However, we expect our capital  expenditures may increase over the next  12 to
18 months due to the expansion of our U.S. presence, our two Phase 3 clinical  trials for  lefamulin  and
the continued enhancements of our information technology infrastructure.

Off-Balance Sheet Arrangements

We  did not have during the periods presented, and we do  not currently  have,  any off-balance sheet

arrangements, as defined under SEC rules, other than our  operating lease obligations for our facilities
in Austria and the United States.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES  ABOUT MARKET  RISK

We  are exposed to a variety of financial risks  in the ordinary course of our business: market risk,
credit risk and liquidity risk. Our overall  risk  management program  focuses on preservation  of capital
given the unpredictability of financial  markets. These market risks  are  principally limited to interest
rate and foreign currency fluctuations.

Market Risk

We  do not have any significant credit risk exposure to any single counterparty or any group of

counterparties having similar characteristics. The credit risk on  liquid funds (bank accounts, cash
balances, marketable securities and term deposits) is limited because the counterparties are  banks with
high credit ratings from international credit  rating agencies.  The primary objective of our investment
activities is to preserve principal and liquidity while  maximizing  income without significantly increasing
risk. We do not enter into investments  for trading or  speculative purposes.

We  are exposed to foreign exchange risk arising from  various currency  exposures, primarily with
respect to the euro and the British pound. Our functional currency is the U.S. dollar, but we  receive
payments from several of our collaborators, and acquire materials, in each of these other currencies.
We  have not established any formal practice  to  manage the foreign  exchange risk against  our  functional
currency. However, we attempt to minimize our  net exposure  by buying or selling foreign currencies at
spot rates upon receipt of new funds  to  facilitate  committed or  anticipated foreign currency
transactions.

 1  C Cs:  37513

Interest rate risk may arise from short-term or  long-term borrowings.  As of December 31, 2016, we

had no borrowings that exposed us to  interest rate risk. As of December 31, 2016, we had  neither
significant long-term interest-bearing assets  nor significant long-term interest-bearing liabilities. Due  to
the short-term nature of our investment portfolio,  we do not believe an immediate 10%  increase in
interest rates would have a material  effect  on the  fair market value of our portfolio, and accordingly  we
do not expect our operating results or cash  flows to be materially affected  by  a sudden  change  in
market interest rates.

Liquidity Risk

Based on our current operating plans, we believe that  our existing cash,  cash equivalents and
short-term investments will be sufficient to fund our operations and capital expenditure requirements at
least into the second quarter of 2018. We  have  based these estimates on assumptions that may prove to
be wrong, and we could use our capital resources sooner than we currently expect.

firm, appear on pages F-1 through F-33  of this  Annual  Report  on Form 10-K.

ITEM 9A. CONTROLS AND PROCEDURES

Conclusions Regarding the Effectiveness of  Disclosure Controls and Procedures

We have carried out an evaluation of the effectiveness of the  design and operation  of our

disclosure controls and procedures (as such term is  defined in  Rules 13a-15(e) and  15d-15(e) under  the
Exchange Act) under the supervision and  the  participation of the company’s management, which is
responsible for the management of the  internal controls, and which includes  our  Chief Executive
Officer and Chief Financial Officer (our principal executive officer and  principal financial officer,
respectively). The term ‘‘disclosure controls and procedures,’’ as defined in  Rules 13a-15(e)  and
15d-15(e) under the Securities Exchange Act of 1934, 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  Securities Exchange Act of 1934 is recorded,  processed,
summarized and reported within the time periods specified  in the Securities and Exchange
Commission’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 Securities Exchange Act of  1934 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. There  are  inherent limitations  to  the effectiveness  of any
system of disclosure controls and procedures, including the possibility of human error and the
circumvention or overriding of the controls and  procedures.  Accordingly, even  effective disclosure
controls and procedures can only provide reasonable assurance of achieving their control objectives.
Based upon our evaluation of our disclosure controls and procedures as of December  31, 2016, our
Chief Executive Officer and Chief Financial Officer concluded that, as  of  such date,  our  disclosure
controls and procedures were effective at a reasonable level of assurance.

Management’s Annual Report on Internal  Control Over Financial Reporting

Internal control over financial reporting refers to the process designed by, or  under the  supervision

of, our Chief Executive Officer and Chief  Financial Officer, and effected  by  our  supervisory board,
management and other personnel, 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, and includes those policies and procedures that:  (1) pertain to the
maintenance of records that in reasonable  detail accurately and fairly reflect the  transactions and
dispositions of our assets; (2) provide  reasonable  assurance that transactions  are recorded as  necessary
to permit preparation of financial statements  in accordance with generally accepted accounting
principles, and that our receipts and  expenditures are being made only in  accordance  with
authorizations of our management and supervisory board;  and  (3) provide reasonable assurance
regarding prevention or timely detection  of  unauthorized acquisition, use  or disposition  of  the
company’s assets that could have a material effect  on the financial statements.

Internal control over financial reporting cannot provide absolute  assurance of achieving financial

reporting objectives because of its inherent limitations. Internal control over financial  reporting is a
process that involves human diligence  and compliance  and  is subject to lapses  in judgment  and
breakdowns resulting from human failures. Internal  control over  financial reporting  also can be
circumvented by collusion or improper management override. Because  of  such limitations, there is a
risk that material misstatements may not be prevented or detected on  a timely basis by internal control
over financial reporting. However, these inherent  limitations  are  known features  of  the financial
reporting process. Therefore, it is possible to design  into  the process  safeguards  to  reduce, though not
eliminate, this risk.

Management is responsible for establishing and maintaining adequate internal  control  over our

financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(e)  under the Exchange  Act.
Under the supervision and with the participation of  our management, including  our  Chief Executive
Officer and Chief Financial Officer,  we  conducted  an evaluation of the effectiveness of our internal
control over financial reporting. Management  has used the framework set  forth  in the report  entitled
‘‘Internal Control—Integrated Framework  (2013)’’ published by the Committee of Sponsoring
Organizations of the Treadway Commission to evaluate  the effectiveness of our internal control over
financial reporting. Based on its evaluation,  management has concluded that our internal control over
financial reporting was effective as of  December 31, 2016, the end of our most recent fiscal year.

Our independent registered public accounting  firm has not performed  an evaluation of our internal

control over financial reporting during  any period  in  accordance with the provisions of  the Sarbanes-
Oxley Act. For as long as we remain an  ‘‘emerging growth  company’’ as defined in the JOBS Act, we
intend to take advantage of the exemption permitting us not to comply  with the requirement that our
independent registered public accounting  firm provide an  attestation on the effectiveness  of our
internal control over financial reporting.

Changes  in Internal Control over Financial Reporting

There were no changes in our internal  control over financial reporting (as defined in Exchange Act

Rule 13a-15(f)) that occurred during  the three months ended December 31, 2016 that have materially
affected, or are reasonably likely to materially affect, our  internal control over financial reporting.

ITEM 10. DIRECTORS, EXECUTIVE  OFFICERS AND CORPORATE GOVERNANCE

PART III

General

We  have a two tier board structure consisting  of  our  management board (Vorstand) and a separate

supervisory board (Aufsichtsrat). The management board is responsible for managing the  business and
represents the company in dealings with  third  parties. The supervisory board  is responsible for
appointing and removing the members  of  the management  board  and supervising the business
conducted by the management board. Although  the supervisory board does not actively manage  the
company, both the Austrian Stock Corporation Act (Aktiengesetz) and our articles of association
(Satzung), together with the management board’s internal rules of procedure (Gesch¨aftsordnung),
require that the prior approval of the supervisory board is obtained before  the management board
takes certain actions. Below is a summary  of relevant information  concerning our supervisory board,
management board and senior management,  as well  as a summary  of  certain significant  provisions of
Austrian corporate law, the articles of association and the  Austrian Stock Corporation Act in respect of
our  management board and supervisory board.

Supervisory Board

Members  of the Supervisory Board

Set forth below are the names and certain biographical information  about each member  of  our

supervisory board members as of December 31,  2016. The information presented includes each
supervisory board member’s principal occupation and  business experience for the past five years and
the names of other public companies of which he has served as a director during  the past five years.

Supervisory Board Responsibilities

Our supervisory board is responsible  for the supervision  of the  activities of our management  board
and  our company’s general affairs and business but does not actively  engage in  the management of the
company. Supervision is exercised by the examination of regular reports  which must be provided by the
management board. The supervisory board  must also approve certain  transactions prior to their
implementation. Our supervisory board may also, on its own initiative, provide the  management board
with advice and may request any information from the management board that it deems appropriate. In
performing its duties, the supervisory board  is required to act in the  interests  of our  company and its
associated business as a whole. The supervisory  board  must convene  a  general  meeting of shareholders
if it is in the best interest of the company. The  members of  the  supervisory board are  not  authorized to
represent us in dealings with  third parties, except  for legal transactions concluded by the  company with
members of the management board and legal proceedings which have  been approved  at a  general
meeting of shareholders against such members.

Members of the supervisory board are appointed by  the general  meeting of shareholders. Pursuant
to our articles of association, the supervisory  board  consists of a minimum of three and a maximum of
ten supervisory board members. Supervisory board members  are appointed at  the general  meeting of
shareholders and may, if not  appointed for  a  shorter  period of time, serve until  the annual meeting
occurring in the fifth calendar year after such board  members’  initial appointment.

Members of the supervisory board may be re-elected. They may also be removed  by  the vote of
three-quarters of the votes cast at the relevant general  meeting of shareholders or resign by written
notice to the company. Resignation upon  written notice  is subject  to  a four-week  notice  period unless
otherwise agreed. In the event an elected member resigns from the  supervisory board before the
expiration of his or her term, the next general  meeting may elect a replacement. The term of  office of
the replacement member runs until the expiration  of  the  original term of the  resigning member. In case
the number of supervisory board members  falls  below three (the  statutory minimum), an extraordinary
general meeting of shareholders must  be  convened to elect  a  replacement.  The supervisory  board

appoints a chairman and a deputy chairman  from among its  members for the entire period of their
respective appointments. The supervisory  board adopts its  own rules of procedure.

The supervisory board meets at least quarterly. At least half of the  members  of the supervisory
board including either the chairman or  the deputy  chairman must be present at a supervisory board
meeting  to constitute a quorum, in each case  however at least three members  need  to  be  present.
Except where a different majority is required  by  law  or the articles of  association, the  supervisory board
acts by  a simple majority of the votes cast. In case of a  split vote,  the chairman casts the deciding  vote.
A member of the supervisory board may authorize in writing  another member of the supervisory board
or any third party to represent him or her  and exercise  his or  her voting  rights. Such representative is
not taken into account in determining a quorum. The right  to  chair a  supervisory board meeting cannot
be transferred.

The supervisory board may also adopt resolutions outside  a meeting, provided that such

resolutions are adopted in writing and submitted  to  all  members  of the supervisory board  and provided
that no supervisory board member objects to adopting resolutions  without  conducting  a meeting. Each
supervisory board member is entitled  to  cast one vote.

Committees of the Supervisory Board

We  have established an audit committee, a  compensation  committee and  a nominating  and

corporate governance committee and have  adopted a charter for each  of  these  committees.

Audit Committee

Our audit committee consists of Charles  A. Rowland, Jr.,  Daniel  Burgess and  Stephen Webster,
and Charles A. Rowland, Jr. is the chair  of the  audit committee. The audit committee  oversees our
accounting and financial reporting processes and the audits of our  consolidated financial statements.
The audit committee is responsible for,  among  other  things:

(cid:127) making recommendations to our supervisory  board regarding the appointment by the  general

meeting of shareholders of our independent auditors;

(cid:127) overseeing the work of the independent auditors, including resolving disagreements between

management and the independent auditors  relating to financial reporting;

(cid:127) pre-approving all audit and non-audit services permitted to be performed by the independent

auditors;

(cid:127) reviewing the independence and quality  control procedures of the independent auditors;

(cid:127) discussing material off-balance sheet  transactions, arrangements  and obligations with

management and the independent auditors;

(cid:127) reviewing and approving all proposed related-party transactions;

(cid:127) discussing the annual audited consolidated and statutory financial statements with management;

(cid:127) annually reviewing and reassessing the adequacy of our audit  committee charter;

(cid:127) meeting separately with the independent auditors to discuss critical accounting  policies,

recommendations on internal controls, the auditor’s engagement  letter  and independence letter
and other material written communications between  the independent auditors and the
management; and

(cid:127) attending to such other matters as  are specifically delegated to our audit  committee by our

supervisory board from time to time.

Our supervisory board has determined  that Charles A. Rowland,  Jr. is an ‘‘audit committee

financial expert’’ as defined in the applicable  SEC rules.

To satisfy the independence criteria for audit committee members  set  forth in  Rule 10A-3 under

the Exchange Act, each member of an audit committee  of a listed company may not, other than in his
capacity  as a member of the audit committee,  the board of directors,  or  any  other board  committee,
accept, directly or indirectly, any consulting, advisory, or other compensatory fee  from the listed
company or any of its subsidiaries or otherwise be an affiliated  person of  the  listed company  or any  of
its  subsidiaries. We believe that the composition  of  our  audit committee meets the  requirements for
independence under current NASDAQ and SEC  rules and  regulations.

The audit committee met five times in 2016.

Compensation Committee

Our compensation committee consists of Axel Bolte, Charles A. Rowland,  Jr. and Chau Khuong,
and Axel Bolte is the chair of the compensation committee. The compensation committee assists the
supervisory board in reviewing and approving or  recommending our compensation structure, including
all forms of compensation relating to  our  supervisory  board members and management. The
compensation committee is responsible for, among other things:

(cid:127) reviewing and making recommendations to the supervisory board with respect to compensation

of our management board and supervisory  board members;

(cid:127) reviewing and approving the compensation, including  equity compensation, change-of-control
benefits and severance arrangements, of our chief executive officer, chief financial officer and
such other members of our management as  it deems appropriate;

(cid:127) overseeing the evaluation of our management;

(cid:127) reviewing periodically and making recommendations to our supervisory board  with respect to any

incentive compensation and equity plans, programs or similar arrangements;

(cid:127) exercising the rights of our supervisory board under any equity plans, except for  the right to

amend any such plans unless otherwise expressly  authorized to do  so; and

(cid:127) attending to such other matters as  are specifically delegated to our compensation committee  by

our  supervisory board from time to time.

To satisfy the independence criteria for compensation committee  members set forth in  Rule 10C-1

under the Exchange Act, all factors specifically  relevant  to  determining whether a member of  a
compensation committee has a relationship to such company  which is  material to that member’s  ability
to be independent from management  in  connection with the duties of a compensation committee
member must be considered, including,  but  not  limited  to: (1) the source of compensation of the
committee member, including any consulting advisory  or other compensatory fee paid  by  such company
to the member; and (2) whether the  member  is affiliated  with the company  or any  of its  subsidiaries  or
affiliates. We believe the composition of our compensation committee  meets the requirements for
independence under current NASDAQ and SEC  rules and  regulations. In determining the
independence of the members of our compensation  committee, our supervisory board  considered that
Mr. Khuong is a private equity partner  at  OrbiMed Advisors, which was the  beneficial  owner of
approximately 14.4% of our outstanding common  shares as of December  31, 2016.

The compensation committee met three times  in 2016.

Nominating and Corporate Governance Committee

Our nominating and corporate governance  committee consists  of Daniel Burgess, Mark Corrigan

and Stephen Webster, and Daniel Burgess  is the chair of the nominating and  corporate governance
committee. The nominating and corporate governance committee  assists the supervisory  board in
selecting individuals qualified to become our  supervisory board members  and in determining the
composition of the supervisory board and its committees. The nominating  and corporate governance
committee is responsible for, among  other things:

(cid:127) recommending to the supervisory board persons to be nominated for election  or re-election to

the supervisory board at any meeting of the  shareholders;

(cid:127) overseeing the supervisory board’s  annual  review of its own  performance and the performance of

its  committees; and

(cid:127) considering, preparing and recommending to the  supervisory board a  set  of corporate

governance guidelines.

The nominating and corporate governance committee met twice in 2016.

Board Meetings and Attendance

Our supervisory board met 14 times  during 2016 and took action by  written  consent  four times.
During  2016, each supervisory board  member  attended  at least 75% of the aggregate of  the number  of
supervisory board meetings held during his or  her term,  and of the  meetings held by all committees of
the supervisory board on which he or she then served.

Our supervisory board members are expected to attend our general meeting of shareholders.  In

August 2016, all of our then-current  supervisory board  members attended our  general meeting  of
shareholders either in person or by telephone.

Management Board Responsibilities

Our management board is responsible for the day-to-day management of our operations under the

supervision of the supervisory board. The management board is required to:

(cid:127) keep  the supervisory board informed in  a timely manner in order  to  allow the  supervisory board

to carry out its responsibilities;

(cid:127) consult with the supervisory board  on  important  matters; and

(cid:127) submit certain important decisions  to the supervisory board for  its approval, as more fully

described below.

Our management board may perform  all acts necessary or useful for  achieving our corporate

purposes, other than those acts that are prohibited by  law  or  by our articles of association, as more
fully discussed below. Members of the management board  of an Austrian  stock  corporation are
appointed by the supervisory board for  a maximum  period of five years and may  be  re-appointed. The
supervisory board may remove a member of the  management board  prior to the  expiration of his term
only for a significant cause, such as a material  breach of duty, the  inability to manage the business
properly or a vote of no-confidence at a  shareholders’ meeting (Vertrauensentzug). The shareholders
themselves are not entitled to appoint or dismiss  the members of the management board.

The management board manages the business and represents the company in  dealings with third

parties and is responsible for the financial  books and records  of  the company. The management  board
is required to report to the supervisory board at least annually regarding  fundamental  questions of
future business policy and the future  development of the  assets and financial situation of the company
(annual report; Lagebericht). The management board is also required to report to the supervisory board
regularly, at least quarterly, on the progress  of business and the results of  the company against the
annual forecast results and considering  future developments to the extent determined  by  Section 81 of
the Austrian Stock Corporation Act (quarterly reports; Quartalsberichte). In addition, the management
board is required to promptly inform the  supervisory board of  any matter that may be of significance to
the company’s business operations, in  particular with respect to any circumstances relating to the
company’s profitability and liquidity (special  report; Sonderbericht). The annual report and the quarterly
report have to be in writing and must  be  explained to the  supervisory  board  on demand.  Each member
of the supervisory board has to be provided with a copy of  these reports.  The special  reports may be
oral reports or in writing.

Under the articles of association, if the management board consists of one  member  only,  this
member may, to the extent permitted by  law, represent the company solely.  If the management board
consists of more than one member, the  company shall be represented by  two members  of the
management board acting jointly or by a one  member of the  management board together with the
holder of a general commercial power of  attorney (Prokurist). The supervisory board may grant
individual members of the management  board the  power  to independently represent the  company.
Currently, our sole management board  member  is empowered with independent  signing authority.

The management board has no obligation to obey orders or directives originating from the general

meeting  of shareholders or the supervisory board. However, both the Austrian  Stock Corporation Act
and our articles of association, together with  the by-laws of our management board, require the  prior
approval of the supervisory board or one  of its committees before the  management board may take
certain actions. A failure by the management  board to obtain such approval does  not  affect the validity
of transactions with respect to third parties, but  may render  the management board personally  liable
for any damages resulting therefrom. Pursuant to our  articles of association, as  well as pursuant  to

initial reports of ownership of our common shares and other equity  securities on  a Form 3 and reports
of changes in such ownership on a Form  4  or Form 5. Our  supervisory board members, management
board member and senior managers  and holders of more  than 10% of our  common shares  are required
by SEC regulations to furnish us with  copies  of all Section 16(a) forms  they file. Prior to the  loss of  our
‘‘foreign private issuer’’ status on January 1,  2017, our supervisory board members,  management board
member, senior managers and holders  of  more than  10% of our common shares were  not  required to
file Section 16(a) reports. However, with the loss  our ‘‘foreign private issuer’’ status, our supervisory
board members, management board member, senior  managers and holders  of more than  10% of our
common shares are now required to  comply with such filing requirements. Based solely on a  review of
our  records and representations made  by  the persons required to file these reports, we believe that,
during the year ended December 31, 2016, our  supervisory board members, management board
member, senior managers and holders  of  more than  10% of our common shares complied with all
Section 16(a) filing requirements applicable to them.

ITEM 11. EXECUTIVE COMPENSATION

The following discussion provides the amount of compensation paid, and benefits  in-kind granted,

by us and our subsidiaries to the members  of our supervisory  board  and certain executives (including
members of our management board  and  senior management) for services provided in all capacities  to
us and our subsidiaries for the year ended  December  31, 2016.

Executive and Director Compensation  Processes

Our executive compensation program is  administered by the  compensation  committee of our

supervisory board, subject to the oversight  and  approval of our full supervisory board. Our
compensation committee reviews our executive compensation practices on  an annual basis and based
on this review approves, or, as appropriate,  makes  recommendations to our supervisory board  for
approval of our executive compensation  program.

In designing our executive compensation program,  our  compensation  committee considers publicly

available compensation data for national and regional  companies in  the biotechnology/pharmaceutical
industry to help guide its executive compensation decisions  at  the time of  hiring  and for subsequent
adjustments in compensation. Since 2016,  our compensation committee has retained Radford, a part  of
Aon Hewitt, a business unit of Aon plc, as its independent compensation consultant,  to  provide
comparative data on executive compensation practices in  our industry  and  to  advise on our executive
compensation program generally. The committee  also has retained Radford for guidelines  and review
of non-employee director compensation.  Although  our compensation  committee considers the  advice
and guidelines of Radford as to our  executive compensation  program, our compensation committee
ultimately makes its own decisions about these  matters. In the future, we  expect  that  our compensation
committee will continue to engage independent compensation consultants to provide additional
guidance on our executive compensation  programs and to conduct further competitive benchmarking
against a peer group of publicly traded companies.

The compensation committee reviewed information regarding the  independence and  potential

conflicts of interest of Radford, taking  into  account, among other things, the factors set forth in  the
NASDAQ listing standards. Based on such review,  the committee  concluded that the engagement of
Radford did not raise any conflict of interest. Outside of services  provided for the compensation
committee, the compensation consultant  provided  nominal  additional  services  to  the company in  2016
related to benchmarking data with respect to certain  non-executive positions in an effort to ensure that
our  compensation practices are competitive  so that we can attract, reward,  motivate and retain all
employees. The total amount paid to Radford in connection  with these additional engagements  was  less
than $120,000 in 2016.

Narrative Disclosure to Summary Compensation  Table

Base Salary

In 2016, we paid annualized base salaries of $436,000 to Dr.  Broom;  $368,740 to Dr. Seltzer; and

$323,200 to Mr. Wolf. In 2015, we paid annualized base salaries of $414,000 to Dr.  Broom; $358,000 to
Dr. Seltzer; and $320,000 to Mr. Wolf.

In February 2017, our supervisory board, following approval  and  recommendation from the

independent compensation consultant,  approved an  increase to the base salaries of our named
executive officers for 2017 as follows:  $457,800 for Dr.  Bloom and $394,552 for  Dr. Seltzer. As
Mr. Wolf had already announced his resignation from the  company,  which became  effective on
February 7, 2017, he did not receive a base salary  increase for 2017. The  supervisory board also
approved 2017 base salaries of Mr. Gelone, our Chief Development Officer, of $353,280  and

Mr. Sender, our Chief Financial Officer,  of $360,500, which also were consistent with the
recommendation of the compensation committee’s independent consultant.

None of our named executive officers is  currently  party  to  an employment  agreement or other

agreement or arrangement that provides  for automatic or scheduled increases  in base salary.

Annual Performance-Based Compensation

Our management board and senior management team,  which includes the  named executive
officers, participate in our performance-based bonus program.  All annual  cash bonuses  for our
executives under the performance-based  bonus  program are tied to the achievement of  strategic and
operational corporate goals for the company, which  are set by the  compensation  committee and
approved by the supervisory board. There are no  discretionary individual goals  under the bonus
program. The 2016 strategic and operational goals for  the company related to the following objectives:

(cid:127) corporate strategy and financial reach, including  executing  on financing  plans, grant

opportunities and development program objectives;

(cid:127) clinical development, including executing on both our Phase  3 clinical  trials and critical path

regulatory activities;

(cid:127) chemistry, manufacturing, and control (CMC),  specifically keeping critical path activities  for

regulatory filing and potential commercial launch  on track;

(cid:127) discovery programs, specifically identifying feasibility and  intellectual property differentiation of

additional compounds; and

(cid:127) communications, including enhancing communications  with key stakeholders.

Under their respective employment agreements, the annual target  bonus for  Dr. Broom is 50%  of

his current base salary and the annual target bonus  for each  of Drs. Seltzer and Gelone  and
Messrs. Sender and Wolf is 35% of their  respective current  base  salaries.

At a meeting held  in January 2017, our  compensation  committee reviewed  the accomplishments  of

the senior management team as measured against the aforementioned 2016 goals.  The  compensation
committee reviewed whether each goal  had been obtained and the weight such  goals should be given in
determining the bonus payout for 2016  performance. Based on its review, the  compensation committee
recommended an 85% payout of the  target  bonuses  for 2016, which was approved by the  supervisory
board on February 7, 2016. Accordingly,  the 2016 bonus payouts were $183,501 for Dr. Broom,
$108,635 for Dr. Seltzer and $96,152 for  Mr. Wolf, who remained employed with us through such  time.

Equity Incentive Awards

We  believe that equity grants provide  our  executives  with a  strong link to our long-term
performance, create an ownership culture  and  help to align the interests of  our executives and our
shareholders. In addition, we believe that  equity grants  with a time-based vesting feature promote
executive retention because this feature  incents our management  board and senior management  team
to remain in our employment during the  vesting period. Accordingly, our supervisory board  periodically
reviews the equity incentive compensation  of  our  management board and senior  management team,
which  includes the named executive officers, and from time to time may grant  equity incentive  awards
to them in the form of stock options.  We also generally make stock option grants  to  new management
team members in connection with the commencement of their employment.

We  have historically granted stock options with  exercise  prices that are set at  no less than the fair

market value  of our common shares  on  the date of grant,  as determined by contemporaneous
valuations and reviewed and approved  by our compensation committee  or our  supervisory board.

Employment Agreements with Management  Board Member  and  Senior  Management

Agreement with Colin Broom, Chief Executive Officer and Management Board Member

Dr. Broom was appointed chief executive officer and  entered into an  employment agreement  dated

and effective  as of August 28, 2014, which  was amended  and  restated as of June 17, 2016. He also
serves on our management board. His  employment  agreement automatically renews each August 28 for
an additional one-year term, unless either we or Dr.  Broom timely provide a notice of non-renewal,  as
described below.

The employment agreement, and Dr. Broom’s employment, may be terminated as  follows:

(1) either party may notify the other, in writing  and not less than 90 days  prior to the applicable term’s
expiration date, of its intention not to renew the term  of employment; (2)  upon Dr.  Broom’s  death or
‘‘disability’’ (as disability is defined in  his employment agreement); (3) at our  election, with or  without
‘‘cause’’ (as cause is defined in his employment agreement); and (4)  at Dr. Broom’s election,  with or
without ‘‘good reason’’ (as good reason is defined in  his employment agreement).

In the event of the termination of Dr. Broom’s employment by us without  cause,  including as  a

result of a termination of his employment  following our delivery  to  Dr. Broom  of  a notice of
non-renewal, or by him for good reason  prior to, or more  than twelve months following, a ‘‘change in
control’’ (as change in control is defined in  his employment  agreement), Dr. Broom will be entitled to
his base salary that has accrued and to which he is  entitled as of the termination date.  In addition,
subject to his execution and nonrevocation of a  release of claims in  our favor and  his continued
compliance with his proprietary rights, non-disclosure and  developments agreement with us, he is
entitled to (1) continued payment of his base salary, in accordance with  our  regular payroll procedures,
for a period of 18 months (2) provided  he is eligible for  and timely elects  to  continue receiving group
medical insurance under COBRA and  the payments would not result in the violation of
nondiscrimination requirements of applicable law, payment by  us of the portion of health coverage
premiums we pay for similarly-situated,  active employees who  receive the same type of coverage, for  a
period of up to 18 months following  his  date of termination, (3) a  lump sum  payment equal  to  any
earned but unpaid annual bonus for a  previously  completed calendar year and (4)  a lump  sum payment
equal to a prorated annual bonus for the  year in  which Dr.  Broom’s employment is terminated based
on the number of days he provided services  to  us  during the year in  which his  employment  is
terminated.

In the event of the termination of Dr. Broom’s employment by us without  cause,  including as  a

result of a termination of his employment  following our delivery  to  Dr. Broom  of  a notice of
non-renewal, or by him for good reason  prior to, or by him for good reason within  twelve  months
following a change in control, subject  (as  described  above  with respect  to certain  payments), to his
execution and nonrevocation of a release  of claims in our  favor and  his  continued compliance with  his
proprietary rights, non-disclosure and developments  agreement with us, Dr. Broom  would be entitled  to
the same payments and benefits as described in  the preceding paragraph,  except that, in lieu of a
pro-rated annual bonus payment, he would be entitled  to  receive a lump sum  payment equal  to  100%
of his  target bonus for the year in which  his employment is terminated and he shall also be entitled to
full vesting acceleration of his then-unvested  equity awards, whether granted under  the Stock Option
Plan 2015 or any successor equity incentive plan, such that  his  equity awards become  fully exercisable
and non-forfeitable as of the termination date.

If Dr. Broom’s employment is terminated for any other reason, including as a result of his  death

or disability, for cause, or voluntarily by  Dr. Broom without  good reason, our  obligations under  the
employment agreement cease immediately,  and  Dr. Broom is only entitled  to  his base salary that has
accrued and to which he is entitled as  of  the termination date  and solely  if  his employment is
terminated as a result of his death or  disability, subject to his execution and  nonrevocation of a release
of claims in our favor and his continued compliance  with his proprietary rights, non-disclosure and

developments agreement with us, he  or his estate,  as applicable, is entitled to any  earned but  unpaid
annual bonus from a previously completed calendar year.

Pursuant to his amended and restated employment agreement, Dr.  Broom  is entitled  to  receive an

annual base salary of $435,999. His base salary is  reviewed by our compensation committee  and
supervisory board in the first quarter  of  each fiscal year  and  any adjustment to his  base  salary is
retroactively effective to the first day of such fiscal year. In addition, Dr. Broom is  eligible for  an
annual discretionary bonus of 50% of his  current base salary. He is  also  eligible  to  receive equity
awards at such times and on such terms  and conditions as the supervisory  board may  determine  and is
also entitled to participate in any and all  benefit  programs  that we make  available to our senior
managers, for which he may be eligible, under the plan documents  governing such programs.

As a condition of his employment, Dr.  Broom signed  a proprietary  rights, non-disclosure and

developments agreement.

Agreements with other Senior Managers

Mr. Sender was appointed chief financial officer and  entered into an  employment agreement  dated

and effective  as of May 2, 2016. Dr.  Seltzer  was  appointed chief  medical officer and entered  into  an
employment agreement dated and effective  as of April  14, 2015, which was amended and restated as of
May 26, 2016. Mr. Gelone was appointed  chief development officer and entered into an  employment
agreement dated and effective as of December  1, 2014, which was amended and  restated as of May 26,
2016. Each of these employment agreements provides that such  senior manager is an at-will employee,
and his or her employment with us can be terminated  by  the respective senior manager  or us at  any
time and for any reason.

The employment agreements and the employment  of  each of Mr. Sender, Dr. Seltzer and

Mr. Gelone may be terminated in one  of three ways: (1) upon the death or ‘‘disability’’ (as disability is

without ‘‘cause’’ (as cause is defined  in the applicable employment  agreement); and (3) at such  senior
manager’s election, with or without ‘‘good  reason’’  (as  good reason is  defined in  the applicable
employment agreement).

In the event of the termination of such senior manager’s employment by us without cause or by

him or her for good reason prior to, or  more  than twelve months  following, a ‘‘change in  control’’ (as
change in control is defined in the applicable employment agreement), such  senior manager will be
entitled to his or her base salary that has accrued and to which he or she is  entitled as of  the
termination date. In addition, subject to such senior manager’s  execution and nonrevocation of a
release of claims in our favor and his or her continued compliance with his or her  proprietary rights,
non-disclosure and developments agreement with us, such senior  manager is entitled to (1) continued
payment of such senior manager’s base  salary, in accordance  with our regular payroll  procedures,  for a
period of 12 months, (2) provided he  or she is  eligible for and timely elects to continue receiving group
medical insurance under COBRA and  the payments would not result in the violation of
nondiscrimination requirements of applicable law, payment by  us of the portion of health coverage
premiums we pay for similarly-situated,  active employees, who  receive the same type of coverage, for a
period of up to 12 months following  the date of termination, (3) a lump sum  payment equal to any

equal to a prorated annual bonus for the  year in  which such  senior manager’s  employment is
terminated based on the number of days  such senior manager provided services to us during the  year in
which  such senior manager’s employment is  terminated.

In the event of the termination of the senior manager’s employment by us without  cause or  by  him

termination date.

If such senior manager’s employment is  terminated for any  other reason, including  as a result of
his or  her death or disability, for cause, or  voluntarily  by  such senior manager without  good reason, our
obligations under the applicable employment agreement  cease immediately, and  such senior manager is

termination date and, solely if such senior  manager’s employment  is terminated  as a result of his or  her
death or disability and subject to his  or  her execution and nonrevocation  of  a release of claims  in our
favor and his or her continued compliance with his or her  proprietary  rights, non-disclosure and
developments agreement with us, such senior manager or the estate of such  senior  manager, as
applicable, is  entitled to any earned but unpaid annual  bonus from  a  previously completed  calendar
year.

Pursuant to their respective employment agreements, each of these  senior  managers  is entitled  to

an annual base salary, as follows: Mr. Sender: $350,000; Ms.  Seltzer: $368,740 and  Mr.  Gelone:
$318,270. Such base salary is reviewed by  our  compensation  committee and supervisory board  in the
first quarter of each fiscal year and any adjustment to such base salary is retroactively effective to the
first day of such fiscal year. In addition, such senior managers  are  eligible  for an  annual discretionary
bonus  of 35% of their current base salary.  Each  senior  manager is  also  eligible  to  receive equity awards
at such times and on such terms and conditions as the  supervisory  board may determine and is  also
entitled to participate in any and all  benefit programs that we  make available  to  our  senior managers,
for which he or she may be eligible,  under the  plan documents governing such  programs.

As a condition to their employment,  each  of Mr. Sender, Dr. Seltzer  and  Mr.  Gelone signed  a

proprietary rights, non-disclosure and developments  agreement.

Stock Option Plan 2015

Our shareholders, management board and  supervisory board adopted our Stock Option Plan 2015
on April 2, 2015, and our shareholders approved an  amended and restated version  of the Stock  Option
Plan 2015 on June 30, 2015. An amendment to the amended  and restated Stock Option Plan  2015 was
approved by our shareholders on July 22,  2015. References to our  Stock Option  Plan 2015 in this
Annual Report refer to the amended  and  restated version  of  the Stock  Option Plan 2015, as amended.
The Stock Option Plan 2015 became effective  on July 3, 2015 upon the  registration with the
commercial register in Austria of our  conditional capital  increase approved  by  our  shareholders on
June 30, 2015. The Stock Option Plan 2015 provides for the grant  of  options  to  purchase  common
shares to our employees, including members  of  our  management board, and to members of our
supervisory board. Following approval  by our shareholders  at our  2016 annual general meeting, the
number of shares available for issuance under the Stock  Option Plan 2015 was  increased to 346,235
common shares. The grant of stock options for 201,568  common  shares  under this plan to members  of
the management board, certain members of the supervisory board  and  certain employees had been
made as of December 31, 2016 at a weighted-average exercise  price of A70.63 ($77.99) per share.

Options granted under the Stock Option  Plan  2015 entitle beneficiaries  thereof  to  purchase  our

common shares at an exercise price equal to 100% of the fair market value per share on  the
beneficiary’s date of participation, which following our  initial  public offering was derived from the
closing sale price of our ADSs on the NASDAQ Global Market. Options granted  under the  Stock
Option Plan 2015 generally vest over four years from  the beneficiary’s date of participation. Typically,
25% of the options subject to a particular grant vest  on the  last day  of  the last calendar month of the
first year of the vesting period, and the remaining 75% vests on  a monthly pro-rata basis  over the
second,  third and fourth years of the vesting  period (i.e., 2.083% per month). Any alternative vesting
period determined by us is subject to approval by our management  board, supervisory board or
shareholders, in accordance with any  applicable voting requirements.

The Stock Option Plan 2015 provides  that, if  a liquidity event (as  defined below) occurs,  all
options outstanding under the Stock  Option Plan 2015 will  be  assumed (or substantially equivalent
awards will be substituted by an acquiring or succeeding corporation (or an affiliate of the  acquiring or
succeeding corporation)), and any then-unvested options shall continue to vest in accordance with the
beneficiary’s original vesting schedule. If a  beneficiary is terminated due to a  good leaver event (within
the meaning of the Stock Option Plan  2015),  on or  prior to the first anniversary  of  the date  of  the
liquidity event, the beneficiary’s options  will  be  immediately exercisable in full  as of the date of such
termination. If the acquiring or succeeding corporation  (or  an affiliate of the  acquiring or  succeeding
corporation) refuses to assume the options  outstanding under  the Stock Option Plan 2015 or to
substitute substantially equivalent options therefor, all  then-unvested options  under the Stock Option
Plan 2015 will automatically vest in full  upon the liquidity event.  For purposes  of  the Stock Option Plan
2015, a liquidity event generally refers  to  an  exclusive  license of or the sale, lease or other disposal of
all or substantially all of our assets, a sale  or other disposal  (but  not a pledge) of 50%  or more of our
shares, a merger or consolidation of  us with or  into  any third party,  or  our  liquidation,  winding up  or
other form of dissolution of us.

Unless otherwise specifically permitted in an  option agreement or resolved upon by the
management board with the approval  of the  supervisory board, the exercise  of vested  options  is
permitted under the Stock Option Plan  2015 only during specified periods and on  specified terms  in
the case of a  liquidity event or following an initial public offering occurring  during  the term of the
option. A beneficiary is entitled to exercise  vested options at any time during the  remaining term of the
option while the beneficiary is providing  services to us, and within  the three-month period following  a
termination of the beneficiary’s services due to a good leaver  event. Options granted under  the Stock
Option Plan 2015 will have a term of  no  more than ten years from the beneficiary’s  date of
participation.

If, during the term of the Stock Option Plan 2015, there is  a change in  our  capital or a

restructuring measure which has an effect  on our capital,  such as a stock  split or reverse stock split,
which  change or measure results in a  change in the value of the options outstanding under the  Stock
Option Plan 2015, the supervisory board, upon a recommendation from the  management board, may
make appropriate  adjustments to the  price or  the amount of such  outstanding options.

No options may be granted under the  Stock Option  Plan  2015 after July 22,  2025, but options

previously granted to a beneficiary may  extend beyond that  date. The supervisory board  may, at any
time, amend, suspend or terminate the Stock Option Plan 2015 in whole or in  part. However, if
shareholder approval is required, including by application of Austrian law, the supervisory board  may
not effect such modification or amendment without such approval.

Stock Option Plan 2007

Our shareholders adopted our Stock Option Plan 2007 on September 12, 2007  and subsequently

approved amendments to the Stock Option Plan 2007 on September, 17,  2009, May  9, 2010 and
June 30, 2015. References to our Stock Option Plan 2007 in  this  Annual Report refer to the plan as
amended. No additional awards will  be  granted under  the Stock Option Plan 2007. The Stock Option
Plan 2007 provided for the grant of up to 29,889 options to certain of our employees, including
members of our management board  and  certain members of our  supervisory board, and other
beneficiaries. As of December 31, 2016,  a total of 10,996 options  were outstanding  at a  weighted-
average exercise price of  A6.72 ($7.32) per share. The options provide for  the right to purchase our
common shares at an exercise price determined by us with the assistance of an Austrian Independent
Certified Public Accountant as of August 24, 2007.

Options granted under the Stock Option  Plan  2007 generally vest over  four years from the date of
participation. Typically, 25% of the options subject to a particular grant  vest  on the last day of the  last
calendar month of the first year of the vesting period, a further 25% of the options  vests  on the  last
day of the last calendar month of the  second year of the vesting period, and the remaining 50% vests
on a monthly pro-rata basis over the  third and  fourth  years  of  the vesting period (i.e., 2.083%  per
month). However, alternative vesting schedules applied for beneficiaries who had worked  for us  prior
to the date of the  adoption of our Stock Option Plan 2007. All options  granted under such alternative
vesting schedules have fully vested.

The Stock Option Plan 2007 provides  that 50% of any then-unvested options shall automatically

vest upon a liquidity event, which refers to an exclusive license of or the sale  or other disposal  of  50%
or more of our assets, a sale or other disposal (but not a pledge) of  50%  or more of our shares, a
merger of ours with any third party, or a  consolidation,  liquidation, winding up  or other form of
dissolution. If a beneficiary has an unjustified  termination  or  a justified premature  termination (as such
terms are used in the Stock Option Plan 2007) within one year of the liquidity  event, all remaining
unvested options held by the beneficiary shall automatically vest in full.

Unless otherwise specifically permitted in an  option agreement or resolved upon by the
management board with the approval  of the  supervisory board, the exercise  of vested  options  is
permitted under the Stock Option Plan  2007 only during specified periods and on  specified terms  in
the case of a  liquidity event or following an initial public offering of  our shares occurring during the
term of the option, regardless of whether or not the beneficiary is  then  providing services  to  us.  A
beneficiary is entitled to exercise vested options at  any time during the remaining term  of the option.
No options may be exercised under the Stock Option Plan 2007 after September 27,  2017. Any options
not exercised by September 27, 2017 automatically terminate  and are forfeited.

If, during the term of the Stock Option Plan 2007, there is  a change in  our  capital or a

restructuring measure which has an effect  on our capital,  such as a stock  split or reverse stock split,
which  change or measure results in a  change in the value of the options outstanding under the  Stock

Option Plan 2007, the supervisory board, upon a recommendation from the  management board, may
make appropriate  adjustments to the  price or  the amount of such  outstanding options.

To date, 22,979 options have been exercised under the Stock  Option Plan 2007.

Founders Program 2007

In November 2007, we granted common  shares and stock options  to  Gerd Ascher and Rodger
Novak as compensation and in recognition of their status as founders of our company. We refer to
these grants as our Founders Program 2007. Under the Founders  Program 2007, a  total  of 4,982
common shares were granted, including 623  common shares granted  in the  form of stock options to
Dr. Novak. The 623 options granted  under the Founders Program 2007 have an  exercise price of A1.00
per  share and all of the options became  fully vested in February 2010.  No other options have  been
granted under the program, and none  of  the options have been exercised.

401(k) Plan

We  maintain a defined contribution employee retirement  plan for our U.S.-based  employees. Our

401(k) plan is intended to qualify as  a tax-qualified  plan under Section 401 of the Internal Revenue
Code, so that contributions to our 401(k) plan, and income earned on such contributions, are  not
taxable to participants until withdrawn or  distributed  from the 401(k) plan. Our 401(k) plan provides
that each participant may contribute  up to 90% of his or her pre-tax compensation, up to a statutory
limit, which is $18,000 for 2017. Participants who  are at least 50  years  old can also make ‘‘catch-up’’

The stock options granted to our non-employee  supervisory board members will have an  exercise

price equal to the fair market value of  our common shares  on  the date of  grant and  will expire ten
years after the date of grant. The initial stock  options granted to our  newly  elected  non-employee
supervisory board members will, subject  to  such member’s continued service on  our  supervisory board,
vest over a three-year period on a monthly pro-rata basis at the end of each successive  month following
the date of the initial grant. The annual stock options  granted to our non-employee  supervisory board
members will, subject to such member’s continued service  on our supervisory board,  vest  fully on the
last date of the month of the first anniversary of the grant  date.

Upon approval of the non-employee supervisory board compensation plan by our shareholders in

August 2016, we paid the members who  had served on the supervisory board prior to the approval
date,  the cash compensation owed to them  under the approved plan  for  their service in 2016 in  a lump
sum payment. Thereafter, the annual  cash fee  will  be  payable in  arrears  in four equal  quarterly
installments payable the week following  the end  of each quarter. The amount of  each  payment will be
prorated for any portion of a quarter  that a member  is not serving on our  supervisory board. Each
non-employee supervisory board member will  also be entitled to reimbursement for  reasonable travel
and other expenses incurred in connection with  attending  meetings of the supervisory board and  any
committee on which he or she serves or otherwise  in direct  service of our company. These amounts are
excluded from the table above.

Compensation Committee Interlocks  and  Insider Participation

For 2016, the members of our compensation  committee were Axel Bolte (chair), Chau Khuong

and Charles Rowland. No member of our compensation committee is,  or  has been,  an officer or
employee of ours or any subsidiary of  ours. None  of  our  executive officers served as  a director or  a
member of a  compensation committee  (or other committee  serving an equivalent function) of any other
entity that had one or more executive officers  serving as a supervisory board member or member  of
our  compensation committee during the year  ended December  31, 2016.

Risk Considerations in Our Compensation Program

Our compensation committee has reviewed and  evaluated the philosophy and standards  on which

our  compensation plans have been developed and implemented  across our company. It is  our belief
that our compensation programs do not encourage inappropriate actions or risk  taking by our  executive
officers. We do not believe that any risks arising from our employee compensation  policies  and
practices are reasonably likely to have a  material adverse effect on our company. In addition, we  do  not
believe that the mix and design of the  components of our executive compensation program encourage
management to assume excessive risks.

ITEM 13. CERTAIN RELATIONSHIPS  AND  RELATED  TRANSACTIONS, AND DIRECTOR

INDEPENDENCE

Board Determination of Independence

Applicable NASDAQ rules require a  majority of a  listed company’s  board  of  directors to be
comprised of independent directors within  one  year of listing.  In addition, the  NASDAQ rules require
that, subject to specified exceptions, each  member  of a listed  company’s audit, compensation and
nominating and corporate governance committees be independent under the Securities Exchange Act of
1934, as amended, or the Exchange Act. Audit committee members must  also satisfy the independence
criteria set forth in Rule 10A-3 under the  Exchange  Act, and  compensation committee  members must
also satisfy the independence criteria set forth in Rule 10C-1 under the  Exchange Act. Under
applicable NASDAQ rules, a director will only qualify as  an ‘‘independent director’’ if, in the  opinion
of the listed company’s board of directors, that person does not have a relationship that would  interfere
with the exercise of independent judgment in  carrying out  the responsibilities of a  director. In order to
be considered independent for purposes  of Rule 10A-3, a member of an  audit committee of a listed
company may not, other than in his or  her capacity as  a member of the  audit committee, the board of
directors, or any other board committee,  accept, directly  or indirectly, any consulting, advisory,  or other
compensatory fee from the listed company or  any  of  its  subsidiaries  or  otherwise be an affiliated person
of the listed company or any of its subsidiaries. In order to be considered independent  for purposes of
Rule 10C-1, the board must consider,  for each member of a compensation committee  of  a listed
company, all factors specifically relevant  to determining whether a director  has a relationship to such
company which is material to that director’s ability to be independent  from management  in connection
with the duties of a compensation committee member, including, but  not  limited  to: (1)  the source of
compensation of the director, including  any  consulting,  advisory or other  compensatory fee paid by such
company to the director; and (2) whether  the  director is  affiliated with the company or  any of  its
subsidiaries or affiliates.

In March 2017, our supervisory board undertook its annual review of the  independence of each

supervisory board member. Based upon  information requested from and provided by each supervisory
board member concerning his background, employment and affiliations, including family relationships,

our  supervisory board has determined  that each of our supervisory  board  members, with the  exception
of George H. Talbot, is an ‘‘independent  director’’ as defined under applicable NASDAQ rules,
including, in the case of all the members  of our audit committee, the independence criteria set forth in
Rule 10A-3 under the Exchange Act,  and  in the case of all  the members of our compensation
committee, the independence criteria  set  forth in  Rule  10C-1 under the Exchange Act. In  making such
determination, our supervisory board  considered  the relationships  that each such supervisory board
member has with Nabriva Therapeutics, including each of the transactions described below in
‘‘—Transactions,’’ and all other facts and circumstances that our supervisory board deemed relevant in
make such independence determination.

Policies and Procedures for Related  Person Transactions

Our supervisory board has adopted written policies and procedures for  the review of any
transaction, arrangement or relationship  in  which Nabriva Therapeutics is  a participant, the amount
involved exceeds $120,000 and one of our  members  of senior management, member of  the supervisory
board, nominee for the supervisory board or  5% shareholder, or their immediate  family members,  each
of whom we refer  to as a ‘‘related person,’’ has  a direct  or indirect material interest.

If a  related person proposes to enter  into such  a transaction, arrangement or relationship,  which

we refer to as a ‘‘related person transaction,’’  the related person must report the proposed related
person transaction to our Chief Financial  Officer or General Counsel. The policy  calls for the proposed
related person transaction to be reviewed and, if deemed appropriate, approved by our audit
committee. Whenever practicable, the reporting, review and  approval  will occur prior to entry into the
transaction. If advance review and approval is not  practicable,  the committee  will review,  and, in its
discretion, may ratify the related person  transaction. The policy also permits the  chairman of the  audit
committee to review and, if deemed  appropriate,  approve proposed  related person transactions that
arise between committee meetings, subject  to  ratification  by the committee  at its next meeting.  Any
related person transactions that are ongoing  in nature will  be  reviewed annually.

A related person transaction reviewed  under the  policy will  be  considered approved  or ratified  if it

is authorized by the audit committee after  full disclosure of the related person’s interest in the
transaction. As appropriate for the circumstances, the audit committee  will  review and  consider:

(cid:127) the related person’s interest in the  related person  transaction;

(cid:127) the approximate dollar value of the amount involved in the related person transaction;

(cid:127) the approximate dollar value of the amount of the  related person’s interest  in the transaction

without regard to the amount of any profit or loss;

(cid:127) whether the transaction was undertaken in the  ordinary  course of our  business;

(cid:127) whether the terms of the transaction  are no  less  favorable  to  us than terms  that  could  have been

reached with an unrelated third party;

(cid:127) the purpose of, and the potential benefits to us of, the  transaction; and

(cid:127) any other information regarding the related person transaction or the related person in the

context of the proposed transaction that would be material to investors in light of the
circumstances of the particular transaction.

Our audit committee may approve or  ratify the transaction  only if it determines that, under  all  of

the circumstances, the transaction is  in  our best interests. Our audit committee may impose  any
conditions on the related person transaction that it deems appropriate.

In addition to the transactions that are excluded by the instructions to the SEC’s  related person
transaction disclosure rule, our supervisory board has determined that the following transactions do not

create a material direct or indirect interest  on behalf  of  related persons  and,  therefore, are not related
person transactions for purposes of this  policy:

(cid:127) interests arising solely from the related person’s position  as an executive officer of  another
entity, whether or not the person is also a director of the  entity, that is a participant in the
transaction where the related person and all other related persons  own in the aggregate  less
than a  10% equity interest in such entity, the related person and his or her  immediate  family
members are not involved in the negotiation  of the terms of the transaction and do not receive
any special benefits as a result of the transaction  and the  amount  involved in  the transaction is
less  than the greater of $200,000 or 5%  of the annual gross revenues of the  company receiving
payment under the transaction; and

(cid:127) a transaction that is specifically contemplated  by provisions  of  our articles of association  or

by-laws.

The policy provides that transactions  involving compensation of  our management board  or senior
managers shall be reviewed and approved by our compensation committee in the manner specified  in
the compensation committee’s charter.

In addition, under our Code of Business Conduct and Ethics,  our employees, management board
member and supervisory board members have  an affirmative  responsibility to disclose any transaction
or relationship that reasonably could  be  expected to give  rise  to  a  conflict of interest.

Transactions

Since January 1, 2016, we have engaged in  the following transactions  with our senior  managers,
management board member, supervisory  board  members and  holders of more than  5% of our voting
securities, and affiliates of our senior  managers, management board member,  supervisory board
members and 5% shareholders. We believe  that all  of the transactions described below were made  on
terms no less favorable to us than could  have  been obtained from unaffiliated  third  parties:

December 2016 Financing

In December 2016, we completed a rights  offering  and  a related underwritten offering  for the  sale
of an aggregate of 588,127 of our common shares (including common  shares represented by American
Depositary Shares, or ADSs). In connection with such offerings, our chief  executive  officer  and our
principal shareholders and their affiliated entities purchased an aggregate  of 102,077 common shares at
a purchase price of A40.14 per common share and an aggregate of 2,865,277  ADSs (representing
approximately 286,528 common shares) at  a purchase price of $4.32  per  ADS.  The  following  table  sets
forth the aggregate number of common  shares and ADSs that  our chief executive officer and our
principal shareholders and their affiliated entities purchased.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Management Board Member  and  Shareholders of Nabriva Therapeutics AG:

In our opinion, the accompanying consolidated balance sheets  and the related  consolidated
statements of operations and comprehensive income (loss), changes in stockholders’ equity &  deficit
and cash flows present fairly, in all material  respects, the financial  position of Nabriva Therapeutics AG
and its subsidiary at December 31, 2016  and December 31, 2015,  and  the  results of their operations
and their cash flows for each of the three years in  the period ended December  31, 2016 in  conformity
with accounting principles generally accepted in the United States of America.  These financial
statements are the responsibility of the Company’s management. Our responsibility is to express an
opinion on these financial statements  based on our  audits.  We conducted  our audits of these statements
in accordance with the standards of the Public Company  Accounting  Oversight Board  (United States).
Those standards require that we plan  and perform the audit to obtain reasonable assurance  about
whether the financial statements are  free of  material  misstatement. An  audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the  financial  statements, assessing the
accounting principles used and significant estimates made  by  management, and evaluating the overall
financial statement presentation. We  believe  that our  audits  provide a reasonable basis for  our opinion.

As discussed in Note 1 to the consolidated financial statements, the Company will require
additional financing to fund future operations and may be required to reduce planned expenditures.

NABRIVA THERAPEUTICS AG

Notes to the Consolidated Financial Statements

(in thousands, except per share data)

1. Organization and Business Activities

Nabriva Therapeutics AG, together with its 100%  owned and consolidated  U.S. subsidiary Nabriva

Therapeutics US, Inc., (‘‘Nabriva’’, ‘‘the Group’’  or the ‘‘Company’’) is  a clinical stage
biopharmaceutical company engaged in  the research  and development  of  novel anti-infective agents  to
treat serious infections, with a focus  on the pleuromutilin class of antibiotics. Nabriva  was incorporated
in Austria as a spin-off from Sandoz  GmbH in  October 2005 and commenced operations in  February
2006. The Company’s headquarters are  at Leberstrasse 20, A-1110 Vienna. Nabriva
Therapeutics US, Inc. was founded and  began operations in the  United States in  August 2014.

Liquidity

Since its inception, the Company incurred net losses and generated negative cash flows  from its
operations. To date, it has financed its operations through the sale of equity securities, including  its
initial public offering of ADSs and private placements of its common shares, convertible debt financings
and research and development support from governmental grants and loans.  As of December 31, 2016,
the Company had cash and cash equivalents and short  term investments of  $83.9 million.

On December 19, 2016, the Company completed a rights offering  and  a  related underwritten
offering for the sale of an aggregate  of 588,127  common shares resulting in  aggregate  gross proceeds of
approximately $24.8 million and net proceeds to us of  approximately  $20.6 million,  after deducting
underwriting fees and offering expenses.

On September 23, 2015 the Company completed its initial public  offering  on the  NASDAQ  Global

Market issuing 9,000,000 ADSs at a price to the  public  of  $10.25 per ADS, representing 900,000 of its
common shares. Each ADS represents  one tenth of a common share.  On September  30, 2015 the
underwriters of its initial public offering exercised in full their over-allotment option  to  purchase  an
additional 1,350,000 ADSs, representing  135,000 common  shares, at the initial  public  offering price  of
$10.25 per ADS, less underwriting discounts. Including the  over-allotment ADSs, the Company  sold  an
aggregate of 10,350,000 ADSs representing 1,035,000 common shares, in its initial public  offering, which
resulted in gross proceeds of approximately  $106.1 million and net proceeds to the Company  of
approximately $92.4 million, after deducting underwriting  discounts and offering expenses.

In connection with the Company’s April 2015 financing, it  sold  730,162 common shares with
contractual preference rights under a shareholders  agreement, including the sale of 511,188 common
shares at a price per share of  A82.35 ($87.71) for A42.1 million ($44.8 million) in cash consideration and
the sale of 218,974 common shares in  exchange for certain  contributions in-kind consisting of the
conversion of outstanding convertible loans and silent  partnership interests. The Company also agreed
to sell a second tranche of common shares with  contractual  preference rights  under the shareholders
agreement to the investors in its April  2015 financing  at their  option for an aggregate purchase price  of
$70.0 million if the Company did not complete a public offering in the  United States within specified
parameters or by a specified date. Upon  the closing of  its initial  public  offering and the issuance of  the
shares for nominal value in satisfaction  of the preferred  dividend  rights,  all contractual preference
rights under the shareholders agreement  terminated.

Between 2011 and 2015 the Company  entered into five convertible loan agreements  with certain of

its  shareholders for proceeds in the aggregate  amount  of  $18.2 million. All outstanding  convertible

loans converted into common shares with contractual preference rights  under  the shareholders
agreement in connection with its April 2015 financing.

The Company entered into silent partnership agreements  with certain  of its  shareholders for
aggregate proceeds of $0.5 million in the  second  quarter of 2014 and $0.9  million in the first quarter of
2015. These agreements have terminated and the related claims for repayment  were converted into
common shares with contractual preference rights under  the shareholders agreement  in connection  with
its  April 2015 financing.

Also during the second quarter of 2014,  the Company entered  into  a A5.0 million ($6.6 million)
loan agreement with Kreos that resulted  in net  proceeds of $6.2  million after deduction of the initial
interest and principal payments and transaction costs at closing. In connection with the  loan agreement,
the Company granted Kreos Capital  IV  (Expert Fund) Limited a warrant  to  purchase  its  common
shares with contractual preference rights under the shareholders agreement, which Kreos Capital IV
(Expert Fund) Limited has exercised in full. As  collateral  for the loan, the Company  pledged its
intellectual property, fixed assets exceeding a  book value of A1,000 the receivables related to the
research premium and our bank accounts.  In July  2015, Kreos Capital  IV (UK)  Limited agreed to
release the Company from the pledge of its intellectual property upon the closing of its initial public
offering. The Company prepaid the Kreos  loan in  accordance with the terms  of the loan agreement  in
November 2015.

The Company expect that its existing cash,  cash equivalents and  short-term investments will be
sufficient to enable it to fund its operating expenses and  capital  expenditure requirements at least  into
the second quarter of 2018 and to obtain  top-line  data  for both its Phase 3 clinical trials of lefamulin.
The Company has based this estimate  on  assumptions that may prove to be wrong, and the Company
could use its capital resources sooner  than it  currently expects.  This estimate assumes, among other
things, that the Company does not obtain  any  additional funding  through grants and clinical trial
support, collaboration agreements or debt  financings.

If the Company is unable to raise capital when needed  or on attractive  terms, it could be forced to

delay, reduce or eliminate its research  and development  programs or  any future commercialization
effort.

2. Summary of Significant Accounting Policies (Continued)

The preparation of financial statements  in conformity with  US GAAP  requires the use of certain
critical accounting estimates. It requires  management  to  exercise its judgment in  the process of applying
the Company’s accounting policies.

Recent  Accounting Pronouncements

At the time of authorization of these  consolidated financial statements for publication, a number
of revisions, amendments and interpretations had  already been published  by the FASB. None of these
are expected to have a significant effect on the consolidated financial  statements  of  the Company,
except the following set out below:

(cid:127) In  May 2014, the FASB issued Accounting Standards Update (‘‘ASU’’) 2014-09, Revenue from
Contracts with Customers, an updated standard on revenue recognition.  ASU 2014-09 provides
enhancements to the quality and consistency of  how revenue is reported by companies while also
improving comparability in the financial statements of companies reporting using  International
Financial Reporting Standards or GAAP. The main purpose  of the new standard is for
companies to recognize revenue to depict  the  transfer  of goods or services to customers in
amounts that reflect the consideration to which a company  expects to be  entitled in exchange for
those goods or services. The new standard also will result in enhanced disclosures about revenue,
provide guidance for transactions that  were not previously  addressed  comprehensively and
improve guidance for multiple-element arrangements. In July 2015, the FASB voted to approve a
one-year deferral of the effective date of ASU 2014-09, which  will be effective  for the  Company
in the  first quarter of fiscal year 2018 and may be applied on a full retrospective or modified
retrospective approach. ASU 2014-09  will have  no impact on the Company  until it  begins  to
generate revenue.

(cid:127) In August 2014, the FASB issued ASU  2014-15, Presentation of Financial Statements—Going

Concern (Subtopic 205-40): Disclosure of Uncertainties about an  Entity’s Ability to Continue as a
Going Concern. ASU 2014-16 explicitly requires management to assess  an entity’s ability to
continue as a going concern, and to provide related footnote disclosures in  certain
circumstances. In connection with each annual and  interim period,  management will assess  if
there is substantial doubt about an entity’s  ability  to  continue as  a  going  concern within  one  year
after the issuance date. Management will consider relevant conditions that  are known, and
reasonably knowable, at the issuance date. Substantial doubt exists  if it  is probable that the
entity will be unable to meet its obligations within one year after the  issuance  date. Disclosures
will be required if conditions give rise to substantial doubt. The  new standard  will be effective
for all entities in the first annual period ending after December  15, 2016. Early  adoption is
permitted. The Company has performed its assessment and determined  that it  has sufficient
financial reasourses to meet its cash  requirements into the second  quarter of  2018.

(cid:127) In  November 2015, the FASB issued ASU 2015-17, Income Taxes: Balance Sheet Classification of
Deferred Taxes. ASU 2015-17 simplifies the balance sheet classification  of  deferred taxes and
requires that all deferred taxes be presented as noncurrent. ASU 2015-17 is effective for  fiscal
years beginning after December 15, 2016 with early adoption permitted. The adoption of  this
update is not expected to have a material effect  on the Company’s financial statements.

2. Summary of Significant Accounting Policies (Continued)

(cid:127) In  January 2016, FASB issued ASU  2016-01, Recognition and Measurement of Financial Assets

and Financial Liabilities. ASU 2016-01 requires equity investments to be measured at fair value
with changes in fair value recognized in net  income; simplifies  the  impairment assessment  of
equity investments without readily determinable fair  values by  requiring a  qualitative assessment
to identify impairment; eliminates the  requirement for public  business  entities to disclose the
method(s) and significant assumptions  used  to  estimate the  fair value that is  required to be
disclosed for financial instruments measured at amortized  cost on  the balance sheet; requires
public business entities to use the exit price notion  when measuring the fair  value of  financial
instruments for disclosure purposes; requires  an entity to present separately in  other
comprehensive income the portion of the  total change in  the fair  value of a  liability  resulting
from a change in the instrument-specific  credit  risk when the entity  has elected to measure the
liability at fair value in accordance with the fair value  option for financial instruments; requires
separate presentation of financial assets  and  financial liabilities by  measurement category and
form of financial assets on the balance  sheet  or the accompanying notes  to the  financial
statements and clarifies that an entity should evaluate  the need for a valuation allowance  on a
deferred tax asset related to available-for-sale securities in combination  with the entity’s  other
deferred tax assets. ASU 2016-01 is effective for financial statements  issued for fiscal years
beginning after December 15, 2017, and interim periods  within those fiscal years. The Company
is currently evaluating the impact that ASU 2016-01  will  have on  its financial  statements  and
related disclosures.

(cid:127) In  February 2016, the FASB issued  ASU 2016-02, Leases (Topic 842). The new standard

establishes a right-of-use (‘‘ROU’’) model that  requires a lessee to record a  ROU asset and a
lease liability on the balance sheet for all  leases with  terms longer than  12 months.  Leases will
be classified as either finance or operating, with classification affecting the pattern of expense
recognition in the income statement. ASU 2016-02  is effective for annual periods beginning after
December 15, 2018, including interim periods within  those annual  periods,  with early adoption
permitted. A modified retrospective transition approach  is required  for lessees for  capital and
operating leases existing at, or entered into after, the beginning of  the  earliest comparative
period presented in the financial statements, with  certain practical expedients  available.  The
Company is currently evaluating the impact  that the standard will  have on its financial
statements and related disclosures.

(cid:127) In  March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment

Accounting, which provides for simplification of certain  aspects  of employee  share-based payment
accounting including income taxes, classification of  awards  as either equity or liabilities,
accounting for forfeitures and classification on  the statement of cash flows. ASU 2016-09 will be
effective for the Company in the first quarter of 2017 and  will  be  applied  either prospectively,
retrospectively or using a modified retrospective transition approach depending  on the area
covered in this update. The Company is currently evaluating the  impact that  the standard will
have on its financial statements and related disclosures.

(cid:127) In  March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers
(Topic  606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)
(‘‘ASU 2016-08’’), in April 2016 issued ASU 2016-10, Revenue from Contracts with Customers

2. Summary of Significant Accounting Policies (Continued)

(Topic  606): Identifying Performance  Obligations  and Licensing (‘‘ASU 2016-10’’), and in May 2016,
issued ASU 2016-11, Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815):
Rescission of SEC Guidance Because of  Accounting Standards Updates 2014-09 and 2014-16
Pursuant to Staff Announcements at the  March  3, 2016 EITF Meeting (‘‘ASU 2016-11’’).
ASU 2016-08 clarifies principal versus agent considerations relating to when another party, along
with the entity, is involved in providing a good  or service to a  customer. ASU 2016-08 requires
an entity to determine whether the nature of its promise is to provide  a  good or service to a
customer, or to arrange for the good or  service  to  be  provided to the  customer by the  other
party. This determination is based upon whether  the entity  controls the good or service before it
is transferred to the customer. When the entity  that satisfies  a  performance  obligation is the
principal, the entity recognizes the gross amount of consideration as revenue. When the entity
that satisfies the performance obligation is the  agent, it  recognizes the amount of  any fee or
commission as revenue. ASU 2016-10  clarifies the guidance  in Topic 606 for identifying
performance obligations in a contract as  well as the  implementation guidance  pertaining to
revenue recognition related to licensing arrangements.  ASU 2016-11 rescinds several SEC  Staff
Announcements that are codified in Topic 605, including,  among  other items,  guidance relating
to accounting for consideration given by  a vendor to a customer, as well as accounting for
shipping and handling fees and freight services. The Company is currently evaluating the impacts
of this standard on its financial statements and anticipates  no significant effects when the
standard is adoped as of the effective date.

(cid:127) In  May 2016, the FASB also issued ASU 2016-12, Revenue from Contracts with Customers—

Narrow-Scope Improvements and Practical Expedients (‘‘ASU 2016-12’’), which provides
clarification on certain topics within ASU 2014-09, Revenue from Contracts with Customers
(Topic  606)(‘‘ASU 2014-09’’), including assessing collectability, presentation of sales taxes, the
measurement date for non-cash consideration and completed contracts at  transition,  as well as
providing a practical expedient for contract modifications at transition. The effective date and
transition requirements for the amendments  in ASU 2016-08,  ASU  2016-10 and ASU  2016-12
are the same as the effective date and transition requirements of ASU  2014-09, which is
effective for fiscal years, and for interim periods  within those  years,  beginning after
December 15, 2017. The Company is currently evaluating the  impacts  of this  standard on  its
financial statements and anticipates no  significant effects when the  standard is adoped as of the
effective date.

(cid:127) In  August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230):

Classification of Certain Cash Receipts and  Cash Payments. The amendments in this ASU
introduce clarifications to the presentation of certain cash receipts and cash payments in the
statement of cash flows. The primary  updates include additions and clarifications of the
classification of cash flows related to certain  debt  repayment activities, contingent consideration
payments related to business combinations, proceeds  from insurance  policies,  distributions from
equity method investees and cash flows related  to  securitized receivables.  This update is  effective
for annual periods beginning after December 15, 2017, including interim periods within  those
fiscal years. Early adoption of this ASU is permitted,  including in  interim periods. The ASU
requires retrospective application to  all prior periods presented  upon  adoption.  The Company is
currently evaluating the impact, if any, that  the adoption of  this guidance  will have  on its cash

flows and/or disclosures, however, the Company does  not  anticipate that the new guidance will
have a significant impact on its financial statements and related disclosures.

(cid:127) In  November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230):

Restricted Cash. ASU 2016-18 requires that a statement of cash flows explain the change  during
the period in the total of cash, cash equivalents, and amounts generally described as restricted
cash or restricted cash equivalents. Therefore, amounts generally  described as restricted  cash and
restricted cash equivalents should be included with cash and cash equivalents  when reconciling
the beginning-of-period and end-of-period total amounts  shown on  the statement of cash flows.
The amendments in this ASU are effective  for public business entities for fiscal years beginning
after December 15, 2017, and interim  periods within those fiscal years. The Company does not
expect the adoption of the amendments to have a material effect on its financial statements and
related disclosures.

Consolidation

The consolidated financial statements  include the financial information  of  Nabriva
Therapeutics AG and its 100% owned  subsidiary, Nabriva  Therapeutics US,  Inc. a Delaware
corporation, founded in August 2014. All  intercompany  balances and transactions are eliminated.

Subsequent Events

Material subsequent events are evaluated and disclosed  through the report issuance date.

Segment Reporting

The Company comprises a single operating and reportable  segment engaged in the  research  and

development of novel anti-infective agents to treat serious infections, with a  focus on the  pleuromutilin
class of antibiotics. The management  team is the  chief operating decision maker, and it reviews the
consolidated operating results regularly  to  make decisions  about the  allocation of the Company’s
resources, and to assess overall performance.

Foreign Currency Translation

Functional and presentation currency

Effective January 1, 2016, the Company’s functional  and  reporting currency changed  to  the U.S.
dollar (‘‘USD’’). Prior to January 1, 2016, the consolidated financial statements were presented in euro
(‘‘A’’), which was the Company’s functional and  presentation currency. With  the expansion  of Nabriva’s
operations to the United States, the Company’s assets, liabilities, revenues and  expenses are  expected
to be predominantly denominated in  USD, and accordingly, the use of USD to measure and  report the
Company’s financial performance and financial  position  was considered to be more  appropriate.  The
impact of the currency translation up  to  January 1, 2016 is recorded in  accumulated  other
comprehensive income (loss). Upon the change in functional  currency on  January 1, 2016,  all  assets and
liabilities of the Company’s operations were  translated from their  euro functional currency into USD
using the exchange rates in effect on  the balance  sheet date, equity was translated at  the historical rates
and revenues, expenses, and cash flows were translated  at the  average rates during the  reporting period

presented. The resulting translation adjustments are  reported under  comprehensive income (loss) as  a
separate component of equity.

Transactions and balances

In preparing the financial statements  of each individual  group entity, transactions  in currencies
other than the entity’s functional currency (foreign  currencies)  are recognized at  the exchange  rates
prevailing at the dates of the transactions. Foreign currency  exchange gains and losses resulting from
the settlement of such transactions and from  the translation at year-end exchange rates  of monetary
assets and liabilities denominated in foreign currencies are recognized in the consolidated statement of
comprehensive income (loss).

Research Premium and Grant Revenue

Grant revenue comprises (a) the research premium  from the Austrian government, (b) grants
received from the Vienna Center for  Innovation and Technology  (Zentrum f¨ur Innovation, or ZIT) and
the Vienna Business Promotion Fund (Wiener Wirtschaftsf¨orderungsfonds, or WWFF) and (c) the benefit
of government loans at below-market interest rates. Please refer to Note  3 for further details on  all
forms of grant revenue.

The research premium was calculated as 10% of  a specified  research  and  development cost base

for the years ended December 31, 2015 and December  31,  2014. For the  year ended December  31,
2016, the research premium is calculated  as 12% of a  specified research  and development  cost base. It
is recognized to the extent the research and development  expenses  have been  incurred. The WWFF
grant is paid out through the landlord in the form of  a monthly reduction in lease payments and is
recognized over the period from grant  date in March  2010 until  end of the lease  termination  waiver
term in December 2017. The ZIT grants are provided to support  specific research projects and are
recognized according to the progress of  the respective  project. All  grants  are non-refundable  as long  as
the conditions of the grant are met. Nabriva  is and  has been in  full  compliance with the conditions of
the grants and all related regulations.

The benefit of a government loan at a below-market  rate of interest is treated as a government
grant. The benefit due to the difference between the market rate of interest and  the rate  of interest
charged by the governmental organization  is measured  as the  difference between the  initial carrying
value of the loan determined and the  proceeds received.  This benefit is deferred,  and recognized
through profit and loss over the term  of the corresponding liabilities.

Research and Development Expenses

All research and development costs are  expensed  as incurred. The following costs, in particular by
their nature, constitute research and development expenses: direct  personnel and material costs, related
overheads for internal or external technology, engineering and other departments  that  provide services;
costs for experimental and pilot facilities (including depreciation of buildings or parts of buildings used
for research or development purposes); costs for  clinical  research; regular costs for  the utilization of
third parties’ patents for research and development  purposes; other taxes  related to research facilities;
and fees for the filing and registration of self-generated patents  that are not  capitalized.

2. Summary of Significant Accounting Policies (Continued)

Leases

Payments made by the Company on  operating leases, mainly in  connection with  the rental
agreements for the premises in Austria  and the  United States, are charged to the consolidated
statement of comprehensive income (loss)  on a straight-line  basis over the period  of  the lease. The
Company has not entered into capital  leases.

Dividend distribution

To date, Nabriva has not paid dividends.  Dividend distribution  to  the Company’s  shareholders shall

be recognized as a liability in the Company’s consolidated financial statements in  the period  in which
the dividends are approved by the Company’s  shareholders.

Property, plant and equipment

Property, plant and equipment are stated at  historical cost less accumulated depreciation and

impairment. Historical costs include the  acquisition price,  ancillary costs and subsequent acquisition
costs less any discounts received on the acquisition price.

Depreciation on assets is calculated using  the straight-line method over the estimated useful  lives

of the assets. In calculating the estimated  useful life, the  economic and technical  life expectancy has
been taken into consideration. The estimated  useful lives  of  property, plant and equipment are  as
follows: 3-5 years for IT equipment,  5-10 years for  laboratory equipment  and 3-10  years  for other plant
and office equipment. The assets’ residual values and useful lives are reviewed, and adjusted  if
appropriate, at each reporting date.

When assets are sold, closed down or  scrapped, the difference between the net  proceeds and the

net carrying amount of the asset is recognized as a gain  or a loss in other operating income or
expenses.

Intangible assets and other long lived  assets

Intangible assets, such as acquired computer  software licenses, are capitalized on the basis of the
costs incurred to acquire the software  and bring it into use. These costs are amortized on a  straight-line
basis over their estimated useful lives  (3-10 years).

Intangible assets and long-lived assets  are assessed for potential impairment when there is  evidence

that events or changes in circumstances indicate that  the carrying amount of an  asset may not be
recovered. An impairment loss would be recognized when an asset’s  fair value, determined based on
undiscounted cash flows expected to be  generated  by the  asset, is less than its carrying amount. The
impairment loss would be measured as the amount by which  the asset’s carrying  value exceeds its fair
value and recognized in these financial statements. Intangible assets  are carried at  cost less
accumulated amortization and impairment.

Short-term Investments

The Company has designated investment  in securities  as available-for-sale securities and  measures

these securities at their respective fair  values. Investments are classified as  short-term or long-term

based on the maturity date and their availability to meet current operating  requirements. Investments
that mature in one year or less are classified as  short-term available-for-sale securities and are reported
as a component of current assets. Investments  that are not considered available for  use in  current
operations are classified as long-term available-for-sale securities  and are  reported as  a component of
long-term assets. Changes in the fair  value of short-term investments are recognized in  other
comprehensive income (loss), with the exception of  interest income  and foreign exchange gains/losses
on monetary financial assets being recognized in the consolidated statement of comprehensive income
(loss).

Excluding the money market fund (see Note 13),  the fair  value  of  the Company’s short term
investments is reported at their respective  carrying amounts given  the short-term nature of these
investments. The fair value of shares in the money market fund are determined by the daily redemption
price at which such shares can be sold, as  quoted daily by the fund  on the basis of the fund’s net  asset
value.

For short-term investments classified  as available-for-sale, a decline in fair value  below  acquisition

cost is considered as an indicator that the securities  are impaired. If any such  evidence exists, the
cumulative loss—measured as the difference between  the acquisition cost and the current fair value
considering any previous recognized  impairments—is removed  from  other comprehensive income and
recognized in the consolidated statement  of comprehensive income  (loss).

Cash and Cash Equivalents

Cash and cash equivalents are classified as cash  on hand and deposits held  on call  with banks and
may include other short-term highly liquid investments with original maturities of three months or  less.
They are recorded at their principal  amount.

Mezzanine Equity

The silent partnership agreements (see Note  17), which entitled  the silent partners to a

proportionate share in the fair value of the Company, similar to a  shareholder, including  a share in
profit or loss, according to an agreed  participation rate,  were  classified as mezzanine equity  pursuant  to
ASC 480, Distinguishing Liabilities from Equity (‘‘ASC 480’’), and ASC 815, Derivatives and Hedging
(‘‘ASC  815’’). The silent partnership interests were  evaluated for equity or mezzanine classification
based upon the nature of the partnerships  settlement provisions which unilaterally  provided the
Company the option to settle the obligation in cash or a  variable  number of shares. However, when a
settlement in shares cannot always be presumed, irrespective of probability of the event occurring,  a
classification outside of stockholders’ equity is  required. Mezzanine equity was initially measured at fair
value and subsequently at the redemption  value  at each reporting period,  representing  the proceeds
resulting from an exit event (trade sale  or  initial public offering), and  such amount recognized  in
retained earnings.

Convertible Loans

The Company presents convertible loans (see  Note 19) as  a  liability  in the  consolidated  balance
sheet. The Company evaluates the requirement  to  bifurcate embedded options within its convertible

loans in accordance with ASC 815. ASC 815 provides criteria that,  if met, require companies to
bifurcate conversion options from their  host instruments. These three criteria include  circumstances in
which  (a) the economic characteristics and risks  of  the embedded  option are not clearly and  closely
related to the economic characteristics and risks of the host contract, (b) the hybrid  instrument is  not
remeasured at fair value under otherwise  applicable generally accepted accounting principles with
changes reported in fair value as they occur, and (c)  a separate  instrument with the same  terms as the
embedded option would be considered  a  derivative  instrument. Discounts  associated with convertible
loans are amortized over the term of  the related  debt using the  effective yield method.

Additional Call Options

The Company accounted for the additional call  options  issued  as a result of the Convertible Loan

Agreement (‘‘CLA’’) and Kreos Loan 2014 pursuant to ASC 815,  which provides a  two-step  model  to
be applied in determining whether a  financial instrument  or an embedded feature is indexed to an
issuer’s own stock. Due to the circumstances that the additional call  options did not meet the ‘‘fixed for
fixed’’ criteria under ASC 815-40, Contracts in Entity’s Own Equity (‘‘ASC 815-40’’), and did not meet
the definition of a  derivative, the additional call options were classified as  a liability. At inception,  the
call options were accounted for at fair  value (determined by use  of  the option  pricing model
(‘‘OPM’’)), and in subsequent periods,  with  changes in fair  value recognized  in the other income
(expense), net line item within the consolidated statement of  comprehensive income (loss).

Prior to the extinguishment or termination of these options during 2015, the  call options were
valued  using the option pricing method. Under this approach, each  class of  securities was modeled as  a
combination of call options with a unique  claim on the assets  of the company. The characteristics of
each  security’s class defined these claims. This  reflected  differences in  value  allocation  at different
company value levels that result from differences in security classes, for  example from liquidation
preference rights, dividend accrual, etc.  The OPM used the Black-Scholes option-pricing model to price
the call options. This model defines the  securities’ fair values as functions of the current  fair value of
the Company and uses assumptions such  as the  anticipated timing  of  a potential liquidity  event and  the
estimated volatility of the entire equity.  Volatility was estimated based on the observed  daily share price
returns of peer companies over a historic period closely matching the period for  which expected
volatility is estimated. Volatility is defined  as the  annualized standard deviation  of share price  returns.
In the allocation of equity, the company  also  considered valuation outcomes through a sale of the
company compared to an initial public offering, and considered  the probabilities  of  each at each
valuation date, since the treatment of the liquidation rights  were different for these two  events. The
aggregate value per security class was then divided by the number of securities  outstanding to arrive  at
the value per security.

The valuations relied on DCF models to derive the total enterprise value.  The cash  flow

projections were based on probability-weighted scenarios which  considered estimates of time to market,
market share and pricing of lefamulin  in  the target indications.  The cash flow  projections were
estimated over a period equal to the  expected patent life,  and a  terminal value  period was not applied.
The expected sales were estimated using  a  detailed market model that  comprises historical and
expected number of therapies as well as  prices  of relevant  drugs  per  indication  and region, based  on
market reports, surveys and estimates  by  management. Production and research and  development costs

were estimated at the indication level  with  general and administrative costs  and selling and marketing
costs estimated at the overall company  level. A  WACC of  16.0%  was applied for each valuation date.
The OPM relies on the anticipated timing and  probability  of  a  liquidity event based  on then  current
plans and estimates of the management as per each valuation date. As of July  4, 2014 and
December 31, 2014 the probability of an initial public offering was estimated at  60% (2013 and
earlier: 10%) and of a sale at 40% (2013 and earlier: 90%).  As of December 31, 2014,  the estimated
volatility was 65% (2013: 80%) based  on  historical trading volatility for  the  publicly traded  peer
companies and a time to liquidity of  0.5  years  for the  IPO  scenario  and  2.5 years for  the trade sales
scenario (2013: 1.2 years and 4.4 years, respectively). As of June 30, 2015,  the time  to  liquidity was
estimated at 0.6 years (June 30, 2014:  1.0 years)  for the  initial public offering scenario and 2.3 years
(June 30, 2014: 3.0 years) for the trade sale  scenario, resulting in an estimated volatility as  of  June  30,
2015 of 55% (June 30, 2014: 65%).

Beneficial Conversion Features

The Company may issue financial instruments that may contain  embedded conversion features. If
these embedded conversion options have  been assessed under ASC 815 for bifurcation and concluded
separate accounting is not required,  further analysis  to  determine if  a  beneficial conversion features
exists is performed. A beneficial conversion feature exists on the date a financial instrument  is issued
when the fair value of the underlying convertible shares  is in  excess  of the effective conversion price
based on the proceeds allocated to the convertible instrument (i.e. intrinsic  value). When determining
the effective conversion price, the fair  value of any attached equity instruments  is considered, if any
related equity instruments were granted  with the original instrument. The intrinsic value  of  the
beneficial conversion feature is recorded  as a debt  discount with a corresponding amount to additional
paid-in capital. The intrinsic value of any  contingent beneficial conversion features is recognized upon
the resolution of the contingency. Depending on  the nature of the instrument, the  beneficial  conversion
feature and contingent beneficial conversion  feature are amortized to either  the earliest date of
conversion or the term of the instrument.

Modification and Extinguishment Accounting

The Company evaluates amendments  to its debt in accordance with ASC  470, Debt (‘‘ASC 470’’),

for modification and extinguishment accounting.  The evaluation includes considering whether the
present  value of cash flows of the new  debt instrument is at least 10  percent different  from the present
cash flows of the old debt instrument as  well as considering the impact of the  amendment to an
embedded conversion option. In situations where  the instruments are not  substantially different,  an
increase in fair value of the embedded  conversion  option was also evaluated.

Employee Benefits

The Company is obliged to pay jubilee benefits in accordance  with the collective bargaining
agreement for the chemical industry,  whereby the employee is  entitled to receive a  jubilee  payment
after being employed for a certain number of years. The Company’s net  obligation  in respect of  these
long-term employee benefits according  to  ASC 710-10-25 is the amount of future benefit that
employees have earned in return for their service in the  current  and prior periods. That  benefit is

discounted to determine its present value. Remeasurements are recognized  in profit  or loss  under
salaries in the period in which they arise.

The Company is further legally required to make monthly  contributions  to a  state plan classified as

defined contribution plan. These contributions are  recognized under expenses  for social security  and
payroll  related taxes.

Share-Based Payments

The Company operates several share-based compensation plans.  The fair  value of such stock-based
compensation is recognized as an expense for the  employee  services received in exchange for the grant
of the options under the Stock Option Plan 2007 and the Stock Option Plan 2015  (see Note 15) or
shares under the Founders’ Program  2007  (see Note 15). Share-based payments to employees and
others providing similar services are  measured at the fair value of the equity awards  at the grant  date
and recognized as an expense over the respective  vesting period.

Since the closing of the IPO, beneficiaries under the Stock Option Plan 2007  and Stock Option
Plan 2015 can exercise their vested options. In the  year  ended December  31, 2016, 14,790  options  have
been exercised.

Social security contributions associated with share-based payment awards are accounted  for as a
liability, which is recognized on the date  of the  event triggering  the measurement and payment  of  the
tax to  the taxing authority; or the date the  options are exercised.

Further, the Company issued substance participation rights to the members of the management

board, which represent a liability award  under ASC 718, Compensation—Stock Compensation (see
Note 15) whereby the Company is obligated to make  cash  payments based  on a certain  formula upon
the occurrence of certain liquidation events only. The  achievement of  such liquidation  events are not
considered probable and so no historical amounts have been recognized as stock-based compensation
expense. As of December 31, 2014, all  substance participation rights were  terminated, hence the fair
value was zero. The nominal amounts  of the  participation rights were  required to be repaid  in cash
even in case of an extraordinary termination, and therefore they had been  recognized separately as a
liability in the consolidated balance sheet.

Income Tax

The Company accounts for income taxes under  the asset and liability method, which requires the

recognition of deferred tax assets and liabilities  for the  expected future tax consequences  of  events that
have been included in the financial statements. Under this  method, we determine  deferred tax assets
and liabilities on the basis of the differences between the  financial  statement and  tax bases of  assets
and liabilities by using enacted tax rates in effect for the  year in which  the differences are  expected to
reverse.  The effect of a change in tax rates on deferred tax assets and liabilities is recognized  in income
in the period that includes the enactment  date.

We  recognize deferred tax assets to the  extent that we  believe that these assets  are more likely
than not to be realized. In making such  a  determination, we consider  all available positive and negative
evidence, including future reversals of  existing taxable temporary  differences, projected future  taxable

income, tax-planning strategies, and results of recent  operations. If we determine  that  we would  be  able
to realize our deferred tax assets in the  future in excess of their net recorded  amount,  we would  make
an adjustment to the deferred tax asset  valuation allowance, which would reduce  the provision  for
income taxes.

In recognizing the benefit of tax positions, the Company has taken or expects to take, the

Company determines whether it is more likely  than not that  the  tax positions will be sustained on the
basis of the technical merits of the position and for those tax positions that meet  the
more-likely-than-not recognition threshold, we  recognize the largest amount of tax benefit that is  more
than 50 percent likely to be realized upon ultimate settlement with the related  tax authority.

(in thousands, except per share data)

8. Income tax (expense) benefit (Continued)

As of December 31, 2016 and 2015 the Company  had  cumulative net  operating loss  carryforwards

of $216.9 million and $162.5 million,  respectively.  The net operating loss carryforwards have no
expiration.

Due to uncertainty regarding the ability to realize  the benefit of deferred tax assets relating to
certain net operating loss carryforwards, valuation allowances  have been established  to  reduce deferred
tax assets to an amount that is more likely than  not  to  be  realized. Realization  of  the remaining net
deferred tax assets will depend on the  generation  of sufficient taxable  income  in the appropriate
jurisdiction, the reversal of deferred tax liabilities, tax planning  strategies and other factors prior to the
expiration of the carryforwards. A change  in the estimates used to make this  determination  could
require a reduction in the deferred tax assets  if they are no longer considered  realizable.

On the basis of this evaluation, as of  December 31, 2016 and  2015, the Company  has recorded a
valuation allowance of $54,114 and $40,487, respectively,  to recognize only the portion  of the deferred
tax asset that is more likely than not to  be realized. The amount of the deferred tax asset  considered
realizable, however, could be adjusted if  estimates  of future taxable  income during the carryforward
period are reduced or increased or if objective negative  evidence in the form of cumulative  losses is no
longer present and additional weight  is given  to  subjective evidence such as our projections for growth.

At December 31, 2016 and 2015, the  Company had no  uncertain tax positions and does  not  expect

any material increase or decrease in income tax expense related to examinations or changes  in
uncertain tax positions.

The Company files income tax returns  in Austria. In  addition, the  Company’s foreign subsidiary

files separate income tax returns in the  United States and state jurisdictions in which they  are located.
Tax  years 2011 and forward remain open  for examination for Austrian tax purposes and  years  2014 and
forward remain open for examination  for the Company’s foreign subsidiary.

The Company’s policy is to record interest and  penalties related to tax matters in income tax

expense.

9. Earnings (Loss) per Share (Continued)

Diluted earnings/losses per share

Diluted earnings/losses per share is calculated by adjusting the weighted average  number of shares

outstanding to assume conversion of  all  dilutive  potential shares. In 2014  and 2015  diluted losses per
share equal basic losses per share. The effect  of  190,432 (2015: 132,706; 2014: 24,133) potentially
dilutive share options has been excluded from the  diluted loss per share calculation because it  would
result in a decrease in the loss per share  for the period and is therefore not  to  be  treated as dilutive.

11. Fair Value Measurement

US GAAP establishes a valuation hierarchy for disclosure of the  inputs to valuation used to

measure fair value. This hierarchy prioritizes the inputs into three  broad levels as follows:

(cid:127) Level 1: Quoted prices (unadjusted)  in active markets for identical  assets or  liabilities.

(cid:127) Level 2: Inputs other than quoted  prices included within Level 1 that are observable for  the

asset or liability, either directly (as prices) or indirectly (as exchange rates).

(cid:127) Level 3: Valuation techniques that  include  inputs  for  the asset or liability  that  are not based on
observable market data (those are unobservable inputs)  and significant to the overall fair value
measurement.

As of December 31, 2016 and December 31, 2015, the Company  held short term investments  (see

Note 13) classified as both Level 1 and  Level  2, and  the Company did not hold any  Level 3 financial
instruments measured at fair value. All  such  instruments, which  included the  call option  liabilities from
the Kreos and CLA loans, were exercised  or terminated in 2015. Prior to  this,  fair values of the call
options (Level 3) were determined using the option pricing model.  There were  no transfers between
Level 1 and 2 in the years ended December 31,  2016 and December  31, 2015. There  were no changes
in valuation techniques during the year  ended December 31, 2016.

Other income (expense) line item in the  consolidated statement  of comprehensive income (loss). The
line item ‘‘Settlement by issued equity  instruments’’ in the table above refers to the exercise of call
options related to  the Kreos Loan 2014  in the amount of $1,420. In addition, the ‘‘Waiver of option
rights’’ line item relates to the waiving of call option rights  by the CLA lenders, and was recorded  as

Stock Option Plan 2007

On September 12, 2007 the Company’s management and supervisory boards resolved to implement

a stock  option plan (‘‘SOP’’) for all employees  (including members of the management board)  with
open-ended contracts of employment  with the  Company and for selected  members of the supervisory
board of the Company and further participants. The stock option plan  became effective on
September 28, 2007 and the shareholders  of the  Company resolved  to  amend the SOP on
September 17, 2009, May 7, 2010 and  June 30, 2015.  The total number of options eligible that can  be
granted and vested in the beneficiaries  under the  SOP does not exceed 29,889 (the overall number  of
options).

15. Share-Based Payments (Continued)

The options grant the beneficiaries the right  to  acquire shares in the Company. The vesting period
for the options is four years following  the grant date. On the  last day of  the last  calendar  month of the
first year of the vesting period, 25%  of  the  options attributable  to  each beneficiary are  automatically
vested. On the last day of the last calendar month  of the second year of  the  vesting  period, a  further
25% of the options are vested. During  the third and fourth  years  of the vesting period,  the remaining
50% of the options vest on a monthly pro  rata basis  (i.e. 2.083% per month).

Notwithstanding any of the above, the exercise of vested options was only permissible in case of a

liquidation event (e.g. sale of 50% or  more of the  shares or  assets of the  Company, merger of the
Company) or a qualified public offering. Since the closing of the initial  public offering of the Company
on September 23,  2015 the beneficiaries  are  entitled to exercise  their  vested options until the  end of
the exercise period on September 27,  2017.

The beneficiaries are not entitled to transfer vested options except to individuals by way of

inheritance or bequest. Options do not  entitle beneficiaries  to  exercise any  shareholder rights.
Beneficiaries may exercise shareholder rights only in  virtue  of  any shares they hold.

As of December 31, 2016, the vested  option rights outstanding under  the SOP 2007 amount to

$2,016 (2015: $4,200, 2014: $4,253) and are recorded under additional paid in capital.

based compensation expense under the  Stock  Option Plan  2007 was $95,  $78, and  $96 for the years
ended December 31, 2016, 2015 and 2014, respectively. We did  not  accrue any income tax benefit

ended December 31, 2016 was $77.70 (2015: $86.60;  2014—not applicable).

Stock Option Plan 2015

On April 2, 2015, the Company’s shareholders, management board  and supervisory board adopted

the Stock Option Plan 2015 and the shareholders approved  an  amended and restated version  of the
Stock Option Plan 2015 on June 30,  2015. An amendment to the amended  and restated  Stock Option
Plan 2015 was approved by the shareholders on  July 22, 2015. The  Stock Option  Plan  2015 became
effective on July 3, 2015 upon the registration with the  commercial register  in Austria of the
conditional capital increase approved by the  shareholders on June 30, 2015. The Stock Option Plan
2015 initially provided for the grant of options for  up to 95,000 common shares  to  the Company’s
employees, including members of the management board, and to members  of the supervisory board.
Following the closing of the initial public offering of the Company,  the overall number of options
increased to 177,499 shares. Following  approval  by the Company’s shareholders at its 2016 annual
general meeting, the number of shares available for issuance  under the Stock Option Plan 2015  was
increased to 346,235 common shares.

Each  vested option grants the beneficiary  the right  to  acquire one  share in  the Company. The
vesting period for the options is four years following the grant date.  On the last day of the  last calendar
month of the first year of the vesting period, 25% of the options  attributable  to  each beneficiary are
automatically vested. During the second,  third and  fourth  years of  the  vesting  period, the  remaining
75% of the options vest on a monthly pro rata  basis (i.e. 2.083% per month).

Since the closing of the initial public  offering of the Company  on September 23, 2015 the

beneficiaries are entitled to exercise their  vested  options until the 10 th  anniversary  of  the date  of  their
participation.

contractual life of the options granted  in  the year ended  December  31, 2016 is  9.2 years (2015:
9.6 years).

As of December 31, 2016, there was  $5,701 of total unrecognized compensation expense, related to

unvested options granted under the plan, which  will  be  recognized over the weighted—average
remaining period of 2.2 years.

Founders’ Program  2007

The Founders’ Program 2007 is a further share-based payment  scheme  the beneficiaries  of which

are Dr. Gerd Ascher and Dr. Rodger  Novak.  There remain 623 shares  available in form of  stock
options at an exercise price of  A1.00 per share and otherwise on the same terms  and  conditions as set
out in the Company’s Stock Option Plan  2007. The 623 options vested as follows: 25% of the  options
(156 shares) vested in November 2007.  A  further  25% (155  shares) vested in February  2008. The
remaining 50% vested during the period from March  2008 to February 2010 on a monthly pro rata
basis (i.e., 2.083%  per month, or 13 shares).  The fair value of each  of  these options  at grant  date is
$144.23 per share. The options are fully vested but not yet  exercised. Therefore,  a balance of $122
(2015: $122, 2014: $122) is recorded  in additional paid in  capital as  at December 31, 2016.  The
corresponding expense was recorded  over  the vesting period  under  other employee benefit  expenses.
No further options were granted under the Founders’ Program 2007, and no options  were forfeited  or
exercised in 2014, 2015 and 2016.

16. April  2015 Financing

On March 31, 2015, the Company entered into an  agreement with  certain existing and new
investors to issue and sell common shares  with contractual preference  rights, including a preferred
dividend right (the ‘‘April 2015 financing’’). The contractual preference rights arose under a
shareholders agreement, signed on April 2, 2015,  by all  shareholders of the  Company (the
‘‘Shareholders Agreement 2015’’) entered into in  connection with the April  2015 financing. In
connection with this financing, the Company  agreed to sell  the shares  in two tranches. In April  2015,
Nabriva closed the sale of the first tranche of 730,162 shares, including the sale of 511,188  shares at a
price per share of $87.71 for $44,836 in cash  consideration and the sale  of 218,974 shares in exchange
for the conversion of outstanding convertible loans and silent partnerships  investments. The Company
also agreed to sell a second tranche of  shares  to  these investors  at the  investors’ option for an
aggregate purchase price of $70,000 if  the Company had not completed a public offering  in the United
States within specified parameters or by a specified date.

In connection with this April 2015 financing, all existing convertible loan agreements and  silent
partnership interests were converted  to  common shares with contractual preference  rights under  the
Shareholders Agreement 2015.

On March 31, 2015, the Company, its  existing investors and  new investors  in the April  2015

financing signed the Investment and  Subscription Agreement 2015, or ISA  2015.

16. April  2015 Financing (Continued)

The signing of the ISA 2015 resulted  in the following effects with respect  to  the Company’s

existing financial instruments:

a)

b)

c)

the lenders under all existing convertible loan  agreements, or CLAs, irrevocably waived  their
claims for payment of interest accrued  on the loan amounts,

all CLA lenders irrevocably waived and acknowledged the  termination  of  their  call option
rights granted under the CLAs, and

all silent partners irrevocably agreed to the forfeiture of their claims  for payment of interest
accrued on their silent partnership investments.

Pursuant to the Company’s shareholders agreement,  signed on April 2,  2015, the holders  of  the
shares issued in its April 2015 financing were  granted certain preferential  rights. These rights include
the right of certain shareholders to acquire  additional common  shares against payment  of  the nominal
amount of A1.00 per share following an appropriate resolution of all  of  its shareholders,  which the
Company refers to as the preferred dividend. The preferred dividend accrued at  a rate  per  annum of
8%, based on the number of days that  have elapsed from the issuance of such  shares until the
occurrence of certain triggering events, including  an initial public offering, a  sale of  the company,
voluntary conversion to preference shares  by  the shareholders,  and a liquidation. The preferred
dividend was  cumulative and perpetual,  and  could be paid in cash or shares based on a shareholders
vote. Upon the closing of the Company’s initial  public offering and the issuance of  the shares for
nominal value in satisfaction of the preferred dividends, all contractual preference rights  terminated in
December 2015.

The shares from the April 2015 financing were recorded upon registration of the  capital increase
in the Austrian commercial register in  May 2015.  As a result of the  preferred dividend  rights, which  are
not legally separable, the Company’s  deemed  to  have issued common shares accompanied by preferred
dividends that may be settled for cash or  shares. Accordingly, the  proceeds from  the April 2015
financing, including the consideration from conversion of the convertible loan agreements  and silent
partnership interests, were recorded  as  mezzanine  equity. A mezzanine equity  classification arises as a
result of the dividend provision in the Shareholders  Agreement 2015,  which the  Company’s
shareholders have covenanted to vote in favor  of the requisite shareholder resolutions  to  allow  it to
satisfy the preferred dividend rights. As a  result,  (i)  the Company’s could not avoid fulfilling the
preferred dividend rights if a triggering  event  occurred that was outside its  control, and  (ii) could not
always presume a settlement in shares. Therefore,  when a  settlement in  shares cannot always be
presumed for an event not solely within the  control  of the issuer, irrespective  of  probability of the
event occurring, a classification outside  of  stockholders’  equity is required. Mezzanine  equity was
initially measured at fair value and subsequently at the redemption value at each reporting period,
representing the proceeds resulting from  an exit event  (trade  sale or initial public offering),  and such
amount recognized in retained earnings.

The April 2015 financing and the related conversion of the Company’s outstanding convertible

loan agreements and silent partnership interests resulted in  total  consideration of $77.3  million which
was recorded in mezzanine equity. Upon the closing of the  Company’s initial  public offering in
September 2015, a triggering event occurred as described above,  and  the  holders of the preferred

dividend right received 17,149 additional shares  against payment of the nominal amount of A1.00 per
share, effectively removing the mezzanine equity classification.

17. December 2016 Financing

On December 19, 2016, the Company completed a rights offering  and  a  related underwritten
offering for the sale of an aggregate  of 588,127  common shares resulting in  aggregate  gross proceeds of
approximately $24.8 million and net proceeds to the  Company of approximately $20.6 million, after
deducting underwriting fees and offering  expenses.

In the rights offering, holders of American Depositary  Shares, or ADSs,  received 0.276  ADS rights

for each  ADS owned of record on November 29, 2016. One ADS right  entitled an ADS  holder  to
subscribe for and purchase one new ADS at the subscription  price of $4.32  per  ADS, the U.S. dollar
equivalent of  A4.014 per ADS. An aggregate of 1,592,750 ADSs, representing 159,275 common  shares,
were subscribed for by holders of ADSs. Each ADS represents one  tenth of a  common share.

In the rights offering, holders of common shares received  the common share  right to subscribe for

and  purchase 0.276 new common shares, at a subscription price of A40.14 per new common share for
each  common share owned of record  on  November  29, 2016. An aggregate of 102,077 new common
shares were subscribed for by holders of common shares.

Pursuant to an underwriting agreement that the Company entered into with Cantor
Fitzgerald & Co., dated December 14,  2016, Cantor Fitzgerald & Co.  agreed to purchase
326,775 common shares, representing  all of the  unsubscribed  common  shares in  the rights offering, at a
purchase price of A40.14 per common share for purposes  of resale of ADSs representing such
unsubscribed common shares.

18. Investment from Silent Partnership

In 2014 and 2015,  the Company issued silent partnership interests which entitled  the silent partners

to a proportionate share in the fair value of  the Company, similar to a shareholder, including a share
in profit or loss, according to an agreed  participation rate. The silent partnership interests represented
a residual interest in the Company. An ordinary  termination by the Company or  the silent partner was
possible after June 30, 2018 and January  31, 2019. Apart from the ordinary  termination, the  parties to
the contracts were also entitled to terminate the contracts early for  material  cause  without observing a
notice period (collectively the ‘‘termination  options’’).

Upon exercise of the termination options, Nabriva had  the unilateral option to settle the obligation

in cash or a variable number of its own  equity instruments. Although share  settlement of such
obligation was within complete control  of  Nabriva, scenarios existed where a  settlement in  shares was
not economically beneficial to Nabriva and as  a result share settlement could not always  be  presumed.
Therefore, the silent partnership interests had  been classified  as mezzanine equity according  to
ASC 480. According to ASC 480, contributions of the  silent partners were initially measured at fair
value with adjustment for the effect of  a  beneficial conversion feature. At  initial recognition, the
intrinsic value of the beneficial conversion feature  was allocated  from the proceeds of the  silent
partnerships to additional paid-in capital, thereby, reducing the associated balance of the silent
partnership interests. Subsequently, the silent  partnership interests were measured  at the redemption

value at each reporting period, representing the  silent partners’ share  in the proceeds resulting  from an
exit event (trade sale or initial public  offering), which has been calculated  by  use of the  option pricing
model. The beneficial conversion feature was amortized from the date  of issuance to the earliest
conversion date of the silent partnership interests.

The Company entered into agreements with  existing and new investors  to  issue and sell common

shares with contractual preference rights under the  Shareholders  Agreement 2015 (‘‘April 2015
financing’’) during the year ended December 31, 2015.  In  connection with this  April 2015  financing  all
silent partnership interests were converted to common shares with  contractual preference rights. At the
time of conversion, a contingent beneficial  conversion feature  was  also recognized immediately prior  to
conversion due to an update to the conversion price  in conjunction  with the  April 2015 financing,
which  was an unresolved contingent event at the time of issuance of  the  silent partnership interests.
The contingent beneficial conversion  feature was allocated to additional  paid in capital,  and fully
amortized upon conversion.

Upon closing of the April 2015 financing all silent  partnerships interests were terminated  and the
respective claims converted into equity.  The  resulting effect on redemption value, which was calculated
using the option pricing model, is shown  under ‘‘Adjustment to fair  value’’ in  the table below. The
amounts outstanding for the silent partnership interests are as follows:

19. Kreos Loan 2014

On July 4, 2014 Nabriva entered into  a loan agreement  with Kreos  Capital IV (‘‘Kreos’’) to obtain

a loan in the amount of $6,643 (‘‘Kreos Loan  2014’’),  payable  monthly. The loan  ranked senior to the
convertible loans. In connection with the  loan  agreement, Nabriva  granted Kreos options to purchase
shares of the Company (‘‘Kreos Options’’). Pursuant  to  the option  agreement dated July 4, 2014  the
number of shares to be issued was calculated by dividing $996 (i.e. 15% of the  loan granted by Kreos
by the price per share of the latest external financing  as of the date of exercise. As collateral for  the
loan, the Company pledged its intellectual  property, fixed assets exceeding a book value of A1,000, the
receivables related to the research premium and its bank accounts. The Company was  allowed  to  sell or
otherwise disburse of any of pledged fixed asset in  the ordinary course of  business,  and also to
withdraw any amounts from the pledged bank accounts, as long  as it  was  not in default of the

On May 13, 2015, Kreos exercised their  call option rights  for  9,107 common shares with

contractual preference rights identical to the preference rights of the  new shares issued in  the April
2015 financing. The conversion price  upon exercise was  $87.71  per  share as agreed  in the April 2015
financing. The fair value of the call options was determined using  the OPM and amounted to $1,420
before reclassification to equity upon  exercise  (See Note 11).

20. Convertible Loans

Between July 2011 and January 2015  Nabriva entered  into five convertible loan agreements
(collectively the ‘‘CLAs’’), with certain of its shareholders.  The lenders had the  right to convert their
entire claim for repayment of the loans  into common shares with contractual preference rights in
Nabriva. Certain of the CLAs were issued  with detachable call options (‘‘Additional Call Options’’). The
key terms of the CLAs and the Additional Call Options are  outlined  below as at December  31, 2015:

(1) Conversion price is $247.54 or the share price agreed  in an  external equity financing  agreement

(where the financing round is at least $5  million).

(2) The shares to  be delivered should  either have the  same rights as  the latest  common shares  with
contractual preference rights issued or the common shares with  contractual  preference  rights
issued in the course of the new equity financing.

(3) Cumulative accrued interest is expected to be paid at maturity of the CLA.

(4) In the event of exercise of the early repayment the lenders  would receive  a repayment  premium

equal to one time the principal amount, i.e. double the  principal  amount.

20. Convertible Loans (Continued)

The conversion options embedded in  the CLAs did  not  meet the definition  of  a derivative  in

accordance with ASC 815. Therefore, the conversion  option was not  bifurcated  from the CLAs.

The proceeds from the CLAs were first ascribed  to  the fair  value of the  Additional Call Options

(if applicable) with the remaining balance  allocated  to  the liability recognized  for the  CLAs.  In
addition, certain of the CLAs have been  adjusted by the effects  of  a  beneficial conversion feature. For
those instruments, the intrinsic value of  the beneficial  conversion  feature at initial recognition was
allocated from the proceeds of the CLAs  to additional paid-in capital, thereby, reducing the value of
the recognized liability. According to ASC 470,  the beneficial conversion feature was amortized  from
the date of issuance to the stated redemption date. The discount associated with Additional Call
Options and the beneficial conversion  features were amortized using the effective yield method  and
recognized in Interest expense in the  consolidated statement of comprehensive income.

The Additional Call Options are detachable  freestanding financial instruments and  were recognized

separately from the CLAs. The Additional  Call Options did  not meet the definition of a derivative
requirements under ASC 815 and ‘‘fixed for  fixed’’  criteria under ASC  815-40.  Accordingly,  the
Additional Call Options were classified as  a  liability.  At inception of the agreements,  the Additional
Call Options were accounted for at fair value (determined  by  use of the  option pricing model), and  in
subsequent periods with changes in fair  value were recognized in  the Other income (expense),  net line
item within the consolidated statement  of comprehensive income (loss). For detail on  the outstanding
balance, change in fair value and the  settlement of the  Additional Call  Option please see the  Level 3
Rollforward table in Note 11.

In conjunction with the issuance of the  fifth  CLA  on January 8, 2015,  the  repayment dates of all
outstanding CLAs were extended to  December 31, 2015. In  accordance with ASC 470,  the extension
was considered a modification. As a  result, the Company recognized a $738 discount as a  reduction to
the CLA balance and an associated increase  in additional paid-in capital  to reflect the increase in the
value of the conversion options related  to  the extension.

In connection with the April 2015 financing all existing CLAs were  converted  to  common shares

with contractual preference rights under  the Shareholders  Agreement 2015  at a  conversion  price of
$87.71 In connection with this April 2015 financing an  Investment and Subscription Agreement was
signed on March 31, 2015 where all existing CLA lenders irrevocably waived their claims for payment
of interest accrued on the CLA amounts  and  agreed to the termination of  the Additional Call  Options
issued in connection with certain CLAs. A contingent beneficial  conversion feature was also recognized
for all CLAs immediately prior to conversion as the conversion price  had been updated in conjunction
with the April 2015 financing, which was  an unresolved  contingent event at the time of issuance of the
CLAs. The contingent beneficial conversion feature was allocated to additional  paid in capital  and fully
amortized and recognized in Interest  expense upon conversion. The outstanding  amounts for  the CLAs
were adjusted for the interest waived  and  the balances were  reclassified into equity  upon issuance of
the new shares based upon the exercise of the conversion option.

The amounts recognized as a result of the modification to the  maturity date  of  the CLAs and

amounts waived by the lenders have been accounted for a capital transaction and recorded in
additional paid-in capital as these were  transactions with  shareholders of the Company and  therefore
considered related parties (See Note 22).

and the recognition of the contingent  beneficial conversion feature upon conversion of
the CLAs into equity of the Company in  Interest expense.

(3) The waiver of interest (as described above) was  recorded in additional paid-in capital with

a corresponding decrease in the CLA balance outstanding.

21. Accrued Expenses and Other Liabilities

Other non-current liabilities include an obligation to pay jubilee benefits  arising  under the
collective bargaining agreement for the  chemical industry, by which  employees are entitled to receive
jubilee payments after being employed for  a certain number of years. For this obligation a provision of
$107 (2015: $84) has been made.

The Company’s net obligation in respect of the jubilee payments is calculated  annually  by  an
independent actuary in accordance with  ASC  710-10-25 using the  projected  unit credit  method. The
principle actuarial assumptions used  were as follows: discount rate of  1.3%  (2015: 2.0%) and retirement
at the age of 61.5-65 for men and 56.5-65 for  women, future annual salary increases of  3%.

Item 4.01 Changes in Registrant’s Certifying Accountant.

(a) Dismissal of Independent Registered Public Accounting  Firm

On May 24, 2017 the Audit Committee  (the  ‘‘Audit Committee’’)  of the Supervisory Board  of
Nabriva Therapeutics AG (the ‘‘Company’’) dismissed PwC Wirtschaftspr¨ufung GmbH (‘‘PwC’’) as the
Company’s independent registered public  accounting  firm.

PwC’s reports on the Company’s consolidated financial  statements for  the fiscal years ended
December 31, 2016 and 2015 did not contain  an adverse opinion or a disclaimer of opinion  and were
not qualified or modified as to uncertainty, audit  scope  or accounting principles, except  that  PwC’s
audit report dated March 24, 2017 on  the December 31,  2016  consolidated financial statements
contained an explanatory paragraph stating that the Company  will require  additional financing to fund
future operations and may be required to reduce planned  expenditures.

During  the fiscal years ended December 31, 2016 and 2015 and the subsequent interim  period

through May 24, 2017, there were no  (1)  disagreements with  PwC on any  matter of accounting
principles or practices, financial statement disclosure,  or auditing scope and procedure, which
disagreements, if not resolved to PwC’s  satisfaction,  would have caused PwC to make reference to the
subject matter of the disagreement in connection with reports for such years;  or (2) reportable events
(as described in Item 304(a)(i)(v) of Regulation S-K).

The Company provided PwC with a copy of the disclosures  it is making  in this Current Report on

Form 8-K and requested from PwC a  letter addressed to the  Securities and Exchange  Commission
indicating whether it agrees with such disclosures. A  copy  of PwC’s letter, dated May 31, 2017, is
attached as Exhibit 16.1 to this Form 8-K.

(b) Engagement of Independent Registered Public Accounting Firm

On May 24, 2017, the Audit Committee  also  approved the engagement of KPMG LLP as  the
Company’s independent registered public accounting  firm for the fiscal year ending  December 31, 2017.
During the fiscal years ended December 31, 2016 and 2015 and the subsequent interim  period through
March 31, 2017, the Company did not consult  with KPMG LLP regarding any of the  matters or  events
set forth in Item 304(a)(2) of Regulation S-K.
