ITEM 1. BUSINESS

Overview

Our Business

We  are  a  clinical  stage  pharmaceutical  company  focused  on  the  treatment  of  highly  resistant  cancers.  We  have  three  core  technologies,  all  of  which  are  based  on
discoveries made at MD Anderson Cancer Center ("MD Anderson"). We have three drug candidates that are active in clinical trials. In 2019, those three drug candidates were
active in four clinical trials in the US and Poland with a fifth that is expected to begin in the first half of 2020. Of these five clinical trials, two are primarily externally funded.
For two of these trials, we successfully concluded the Phase 1 portion recently and are preparing to potentially move into Phase 2 trials. We anticipate laying the groundwork in
2020 for two additional Phase 1 trials expected to begin in 2021 sponsored by us and two other Phase 1 trials we expect to be externally sponsored.

Based on our positive clinical activity thus far, we have narrowed our development focus to our nearest term opportunities. We believe this will allow us to reduce our
cash needs until we reach a significant value inflection point, although we will continue to require additional external capital during this period. In addition, institutional support
for our technologies has increased and we believe such support may provide outside funding to help reduce future dilution.

Of  our  three  clinical  stage  drug  candidates, Annamycin  is  being  studied  for  the  treatment  of  relapsed  or  refractory  acute  myeloid  leukemia  (“AML”)  and  cancers
metastasized  to  the  lungs.  WP1066,  an  Immune/Transcription  Modulator  ("p-STAT3  inhibitor")  is  intended  to  target  a  wide  range  of  tumors,  including  brain  tumors  and
pancreatic cancer. We began and completed a Phase 1 clinical trial in 2019 in Poland for a third drug, WP1220 (a molecule similar to WP1066), for the topical treatment of
cutaneous T-cell lymphoma ("CTCL") and we are looking to expand development of this drug into a Moleculin Phase 2 trial. We are also engaged in preclinical development of
additional drug candidates, including additional Immune/Transcription Modulators, as well as Metabolism/Glycosylation Inhibitors.

We  consider  Annamycin  to  be  a  "next  generation"  anthracycline,  unlike  any  currently  approved  anthracyclines,  as  it  is  designed  to  avoid  multidrug  resistance
mechanisms with little to no cardiotoxicity (two problems common to all currently approved anthracyclines). We recently received an independent expert cardiology assessment
confirming the absence of cardiotoxicity in the first 14 patients treated with Annamycin in both our US and European Phase 1 clinical trials, validating Annamycin's lack of
cardiotoxicity. Annamycin is currently in one Phase 1/2 clinical trial in Europe with the Phase 1 portion of another Phase 1/2 AML trial recently concluding in the US. Upon
receipt of further data from the European Phase 1 trial, we plan to seek agreement with the FDA for accelerated approval of Annamycin based on a pivotal Phase 2 AML trial
sponsored by us, although there is no assurance that the FDA will agree with our proposal.

In  2019,  preclinical  work  on  Annamycin  demonstrated  activity  against  some  cancers  metastasized  to  the  lungs.  With  this  new  data,  we  are  planning  to  start  a

Moleculin-sponsored US Phase 1 trial at MD Anderson for the treatment of cancer metastasized to the lungs with Annamycin.

WP1066 is one of several Immune/Transcription Modulators designed to stimulate the immune response to tumors by inhibiting the errant activity of Regulatory T-
Cells (TRegs) while also inhibiting key oncogenic transcription factors, including p-STAT3, c-Myc and HIF-1α. These transcription factors are widely sought targets that may
also  play  a  role  in  the  inability  of  immune  checkpoint  inhibitors  to  affect  more  resistant  tumors.  WP1066  is  currently  in  an  US  physician-sponsored  Phase  1  trial  for  the
treatment  of  glioblastoma  ("GBM")  and  another  institutionally  sponsored  Phase  1  trial  should  begin  soon  for  the  treatment  of  pediatric  brain  tumors. Another  physician-
sponsored Phase 1 trial is being considered for the treatment of GBM with WP1066 in combination with radiation.

We are also developing new compounds designed to exploit the potential uses of inhibitors of glycolysis such as 2-deoxy-D-glucose (“2-DG”), which we believe may
provide an opportunity to cut off the fuel supply of tumors by taking advantage of their high level of dependence on glucose in comparison to healthy cells. A key drawback to
2-DG  is  its  lack  of  drug-like  properties,  including  a  short  circulation  time  and  poor  tissue/organ  distribution  characteristics.  Our  lead  Metabolism/Glycosylation  Inhibitor,
WP1122, is a prodrug of 2-DG that appears to improve the drug-like properties of 2-DG by increasing its circulation time and improving tissue/organ distribution. New research
also points to the potential for 2-DG to be capable of

3

 
 
enhancing the usefulness of checkpoint inhibitors. Considering that 2-DG lacks sufficient drug-like properties to be practical in a clinical setting, we believe WP1122 has the
opportunity to become an important drug to potentiate existing therapies, including checkpoint inhibitors. In March 2020, we entered into an agreement with an outside research
center who will conduct research on WP1122 for antiviral properties against a range of viruses, including Coronavirus.

We do not have manufacturing facilities and all manufacturing activities are contracted out to third parties. Additionally, we do not have a sales organization.

Mission and Strategy Overview

Moleculin is focused on developing treatments for highly resistant cancers. These include AML, glioblastoma, cutaneous t-cell lymphoma, pancreatic cancer, lung and
other vital organ metastases, and others. Our diverse pipeline of technologies was built around the recognition that many highly resistant tumors tend to have a common set of
traits, including an increase in multidrug resistant mechanisms, an evasion of the natural immune system, a marked upregulation of certain key oncogenic transcription factors
and an increased dependence on glycolysis for energy production. We believe each of these elements may be addressed by the unique and innovative mechanisms introduced by
one or more of our three core technologies.

We believe this approach not only provides the opportunity to help the many patients in need of alternative therapies, but also to work in combination with numerous
existing technologies that often fail as tumors present immediate or acquired resistance. We believe showing even modest improvements in highly resistant cancers may lead to
accelerated approval pathways, potentially reducing the time and capital required to ultimately realize success.

In 2019 we announced our out-licensing agreement to WPD Pharmaceuticals, an entity associated with our founder, Dr. Waldemar Priebe. This involved providing
territorial rights to certain smaller countries in mainly Eastern Europe and Western Asia in exchange for their agreeing to provide an additional $4 million or more of funding to
our development efforts over the next four years. As we are beginning to generate real human data, we intend to pursue additional strategic collaborations.

This increase in potential outside funding should allow us to concentrate our internal resources primarily on Annamycin, and our active p-STAT3 inhibitors, WP1066
and  WP1220.  This  allows  us  to  prioritize  our  internal  funding  to  core  clinical  trials  that  we  think  may  lead  to  an  accelerated  approval  pathway  and/or  a  strategic  licensing
opportunity. Accordingly,  we have increased our focus on clinical trial pathways for Annamycin and WP1220. We have now seen human activity in both drug candidates that
we think is capable of supporting an accelerated approval pathway.

Intellectual Property Overview

Drug development – from discovery to approved drug – can take decades. With this in mind, and in light of the fact that US patent terms begin on the date of filing and
run for only 20 years, alternative means of establishing market exclusivity are common in the drug development industry. Orphan Drug designation (“ODD”) from the FDA is
available  for  drugs  targeting  diseases  with  less  than  200,000  cases  per  year.  ODD  may  enable  market  exclusivity  of  7  years  from  the  date  of  approval  of  a  New  Drug
Application  (“NDA”)  in  the  United  States.  During  that  period  the  FDA  generally  could  not  approve  another  product  containing  the  same  drug  for  the  same  designated
indication. Orphan Drug Exclusivity will not bar approval of another product under certain circumstances, including if a subsequent product with the same active ingredient for
the same indication is shown to be clinically superior to the approved product on the basis of greater efficacy or safety, or providing a major contribution to patient care, or if
the company with orphan drug exclusivity is not able to meet market demand. Also available for application from the European Union (“EU”) is ODD where, once granted,
extends market exclusivity to 10 years from the date of Marketing Authorization Application (“MAA”). The ODD in the EU is generally available for drug products to treat life-
threatening or chronically debilitating conditions affecting not more than five in 10,000 persons in the EU when the application is made. The 10 year period can be reduced to
six years if, at the end of the fifth year, it is established that the product no longer meets the criteria for the ODD, for example because the product is sufficiently profitable not to
justify market exclusivity.

We have been granted royalty-bearing, worldwide, exclusive licenses for the patent and technology rights related to all three of our drug technologies, as these patent
rights are owned by MD Anderson. The Annamycin drug substance is no longer covered by any original patent protection, however in June 2019, we submitted new provisional
patent  applications  for  synthetic  processes  for  lyophilized  Annamycin  and  for  reconstitution  of  our  Annamycin  drug  product  candidate.  If  the  non-provisional  patent
applications are approved, for which we can provide no assurance, this would potentially provide patent protection for Annamycin through June 2040.

4

Independently from potential patent protection, in 2018 we received ODD from the FDA for Annamycin for the treatment of AML and, in 2019 we received FDA ODD
for WP1066 for the treatment of glioblastoma. Separately, the FDA may also grant market exclusivity of 5 years for newly approved new chemical entities (which our drug
candidates are considered to be), which would preclude approval of any generic drug application or 505(b)(2) application attempting to copy our drugs, but there can be no
assurance  that  such  exclusivity  will  be  granted  or  that  a  third  party  could  apply  as  an  NDA  under  505(b)(1).  Furthermore,  we  were  granted  Fast  Track  Designation  for
Annamycin for the treatment of relapsed or refractory AML in April 2019 by the FDA. Fast Track Designation is granted to potentially expedite drug development and approval
and is granted to drugs intended to treat serious conditions, where data demonstrate the potential to address an unmet medical need.

The US patents we license from MD Anderson that have been granted expire from 2024 to 2029. MD Anderson manages the patent process related to the technology
subject to our license agreements worldwide with advice from us. Additional patents pending, also licensed from MD Anderson, may provide additional potential exclusivity to
our drug portfolio, however we can provide no assurance that such patents will be granted.

Our Drug Candidates

Annamycin

One of our lead product candidates is Annamycin, for which FDA allowed an IND to go into effect for a Phase 1/2 trial for the treatment of relapsed or refractory AML
and granted Orphan Drug Designation for the treatment of AML, which means the agency believes we have established a medically plausible basis for expecting the drug to be
effective. We recently concluded the Phase 1 portion of the US clinical trial and we are planning a potential pivotal Phase 2 trial once we have additional clinical data. A similar
Phase 1/2 trial in Europe continues and is in its fourth cohort.

Prior Development

We took over the development of Annamycin after two prior drug development companies, Callisto Pharmaceuticals and Aronex Pharmaceuticals, ceased development
work for various clinical and business reasons, leading to the termination of the INDs by the FDA. The basis for our decision to proceed notwithstanding the most recent prior
developer’s abandoning the project is that we believe the actual clinical data as reported by Dr. Robert Shepard, our Chief Medical  Officer  and  the  prior  developer’s  Chief
Medical  Officer  at  the  time  of  the  clinical  trials,  to  the  2009  Annual  Meeting  of  the  American  Society  of  Clinical  Oncology,  and  as  further  reported  by  the  Principal
Investigators of the clinical trials in a peer-reviewed journal article (Clin Lymphoma Myeloma Leuk. 2013 August; 13(4): 430-434. doi:10.1016/j.clml.2013.03.015.), supports
further clinical evaluation. In addition, the conclusion published in the 2013 Clinical Lymphoma, Myeloma & Leukemia Journal article was that “Single agent nanomolecular
liposomal annamycin appears to be well-tolerated and (demonstrates) evidence of clinical activity as a single agent in refractory adult ALL.” As reported in both the ASCO
presentation and the 2013 journal article referenced, the definition of efficacy is based on the following Response Criteria: “Response criteria were achievement of CR defined
as ≤5% blasts, granulocyte count of ≥1×109/L, and a platelet count of ≥100×109/L. Partial remission was defined the same as CR, except for the presence of 6% to 25% blasts.
Hematologic improvement was defined as for CR but platelet count of ≥1×109/L.” The summary of patient response from the 2013 journal article reads: “After determining the
MTD,  a  10-patient  phase  IIA  was  conducted.  Eight  of  the  patients  completed  one  cycle  of  the  three  days  of  treatment  at  the  MTD.  Of  these,  five  (62%)  demonstrated
encouraging  anti-leukemic  activity  with  complete  clearing  of  circulating  peripheral  blasts.  Three  of  these  subjects  also  cleared  bone  marrow  blasts  with  one  subsequently
proceeding onto successful stem cell transplantation. The other two subjects developed tumor lysis syndrome and unfortunately expired prior to response assessment.” In our
review of these trials, we confirmed that the activity demonstrated in this summary corresponds with a “Partial remission” as described in the Response Criteria and that the
three subjects who “cleared bone marrow blasts” correspond with “CR” (Complete Response).

The Callisto trial was the second trial to study Annamycin in acute leukemia. The first trial was sponsored by Aronex Pharmaceuticals. When Callisto acquired the
technology and made changes in manufacturing methods, they had to conduct another Phase 1 dose ranging trial. Unexpectedly, that trial yielded a significantly different result
than the Aronex trial.

The Aronex trial started at 190 mg/m2, which was expected to be, and in fact was, sub-therapeutic. In accordance with the dose-ranging protocol, dosing was then
increased until it reached 350 mg/m2, where DLTs (dose limiting  toxicities)  forced  a  de-escalation  back  to  an  MTD  (maximum  tolerated  dose)  of  280  mg/m2. Although  the
Callisto trial restarted at the same 190 mg/m2 starting dose used in the Aronex trial, there were immediate instances of DLTs (mucositis), causing the dosing to be reduced
instead of escalated. Ultimately, the Callisto trial settled on 150 mg/m2 as the MTD where, during the expansion (Phase 2a) portion of the trial, therapeutic activity was noted.

5

The production of liposome formulated anthracyclines is very sensitive to subtle changes in production method and starting materials. It is partly for this reason that,
more than 10 years later and with entirely new contractors, we had to run yet another Phase 1 dose ranging study. Although we cannot be sure until the trial is completed, based
on our experience to date in our European Phase 1/2 trial, we believe that our product appears to be performing more closely to the Aronex product rather than the Callisto
product. This suggests that our Phase 1/2 trial will run longer than originally expected, as we may have to reach 300 mg/m2 or higher before establishing the MTD.

The Importance of No Cardiotoxicity

Chemotherapy continues to be a cornerstone of cancer therapy. Despite the progress made with immunotherapy and precision medicine, the first-line treatment for
many cancers continues to include chemotherapy. And, in part because of the emphasis placed on alternatives to chemotherapy, we believe that not enough has been done to
improve  chemotherapeutic  agents  to  make  them  safer,  especially  with  regard  to  cardiotoxicity  (damage  to  the  heart)  ,  and  more  effective. Anthracyclines  are  a  class  of
chemotherapy drugs designed to destroy the DNA of rapidly producing cancer cells. Acute leukemia is one of a number of cancers that are usually treated with anthracyclines.
In the case of acute leukemia, anthracyclines are typically used in “induction therapy,” where the goal is often to induce sufficient remission of patients’ blood-born tumor cells
to allow for a potentially curative bone marrow transplant.

Two  key  factors  limit  the  safety  and  effectiveness  of  anthracyclines:  cardiotoxicity  and  multidrug  resistance.  We  believe Annamycin  may  significantly  reduce  the
impact of these two factors. If early human data from the clinical activity thus far is borne out, of which there is no assurance, Annamycin may ultimately provide clinically
meaningful  benefits  over  currently  approved  anthracyclines  in  treating  certain  cancers.  Preliminary  data  from  very  early-stage  clinical  trials  suggest  acute  leukemia  as  a
potentially opportune indication in which to further study Annamycin.

One of the key dose-limiting toxicities associated with currently available anthracyclines (including the anthracycline in the approved drug, Vyxeos) is the propensity
to induce life-threatening heart damage (also known as cardiotoxicity). This is a particularly significant risk for pediatric leukemia patients, whose life spans can be severely
shortened by the induction therapy intended to cure them of acute leukemia. In the animal model recommended by the FDA as an indicator of human cardiotoxicity, the non-
liposomal  (free)  form  of  Annamycin  has  been  shown  to  be  significantly  less  likely  than  doxorubicin  to  create  heart  lesions  in  mice,  and  the  liposomal  formulation  (L-
Annamycin) has been shown in these same models to have reduced cardiotoxicity to the point where it is unlikely to cause harm to human patients. If this characteristic is shown
to be the same in humans, it may allow Annamycin to be used more aggressively to help patients achieve remission. This would be especially valuable in the case of pediatric
acute leukemia (both AML and ALL) because of the potential impact of cardiotoxicity on long-term survival. In our current Phase 1/2 trial for Annamycin, we are collecting
data to further validate the design intent of Annamycin to have little or no cardiotoxicity. Unless otherwise noted, all of our references to Annamycin refer to the liposomal form
(L-Annamycin).

In addition, the effectiveness of currently approved anthracyclines is limited by their propensity for succumbing to “multidrug resistance.” This can occur where, as a
natural defense mechanism, transmembrane proteins acting as transporters (one type of which is referred to as a “P-glycoprotein pump” or “ABCB1 transporter”) develop on
the outer surface of cells to expel perceived threats like anthracyclines. In many instances, the likelihood of cardiotoxicity (and other serious side effects) prevents increasing the
dosing of current therapies in order to overcome multidrug resistance. As a result, most patients cannot receive current anthracyclines in doses that are adequate to produce
lasting remission and thereby qualify for a bone marrow transplant. A laboratory study has suggested that Annamycin may resist being expelled by P-glycoprotein pumps and
similar multidrug resistance transporters, which may mean the drug circumvents multidrug resistance. This characteristic has been shown in pre-clinical testing to allow for
higher drug uptake in diseased cells, which we believe could allow for more effective induction therapy with less risk to the patient, especially in relapsed patients.

Additionally, preclinical research in animal models at MD Anderson demonstrated that Annamycin is able to significantly improve survival in an aggressive form of
triple negative breast cancer metastasized to the lungs in animal models. Coupled with research in animal models demonstrating that Annamycin is capable of accumulating in
the lungs at very high levels, this suggests that Annamycin may be well suited to become a treatment for lung-localized tumors.

In all instances, it will be important to develop additional clinical data regarding the early indications from preclinical and early clinical data, as discussed below.

We filed our IND application for Annamycin, with the clinical strategy of increasing the MTD mentioned above, in February 2017, which was allowed in September
2017. The FDA limited dosages to patients to a lifetime maximum anthracycline exposure of 550 mg/m2 which in effect limited the maximum dose in our trial to 120 mg/m2.
Patient treatment began in the US in March 2018.

In August 2017, we met with the European Medicines Agency (“EMA”) to discuss a CTA (Clinical Trial Authorization) in Europe for the study of Annamycin for the
treatment of AML. In December 2017, the Ethics Committee in Poland approved our Phase 1/2 trial of Annamycin for the treatment of relapsed or refractory AML. A final
approval is required by the Polish National Office which was received in June 2018. This enabled our Phase 1/2 clinical trial there to study Annamycin for the treatment of
relapsed or refractory AML to begin. The EMA did not impose a lifetime maximum anthracycline exposure limit in this trial.

In February 2020, we announced that our open label, single arm US Phase 1 portion of a Phase 1/2 trial had concluded its second cohort and met its primary objective
of demonstrating the safety of Annamycin in treating relapsed or refractory AML. We also announced an update on interim enrollment, safety and efficacy data in our parallel
Phase 1/2 trial in Europe.

We continue to recruit and contract with clinics in our European trial, which is being conducted in Poland. We can provide no assurance of additional recruitment or

that treatments will occur in the near term and on a timely basis, if at all.

As  of  February  2020,  12  patients  have  been  dosed  in  Europe  and Annamycin  has  proven,  thus  far,  to  be  safe  and  tolerable  and,  importantly,  there  have  been  no
instances of cardiotoxicity in any patient. To date, only one adverse event related to Annamycin has been reported in the European trial; a patient experienced grade 2 mucositis
that resolved to grade 1 within 2 days. The European patients have been dosed at levels ranging from 120 mg/m2 to 210 mg/m2, with, as of this report, 3 patients having been
enrolled in the fourth cohort in Europe receiving a single dose of 210 mg/m2.

Study Design -

We have been studying Annamycin in both the US and Europe in open label, single arm clinical trials to assess the safety and efficacy of Annamycin for the treatment
of adults with relapsed or refractory acute myeloid leukemia. The US and European trials have essentially the same study design, consisting of a Phase 1 intended to establish a
"Recommended  Phase  2  Dose"  (RP2D),  to  which  the  studies  may  then  proceed.  The  Phase  1  studies  provide  for  escalating  doses  in  cohorts  of  3  patients  each,  with  each
successive cohort receiving the next higher dose level until "dose limiting toxicities" prevent further increases. Cohorts 1, 2 and 3 in Europe received a dose of 120, 150 and 180
mg/m2, respectively, and the results have permitted moving to Cohort 4 with dosing at 210 mg/m2, in which all 3 patients have been enrolled and treated. Cohort 1 in the US
started at 100 mg/m2, and the results supported moving to Cohort 2 at 120 mg/m2, which has now been fully recruited, treated, and evaluated. Beyond this dose level, patients
would receive greater than the lifetime maximum anthracycline dose of 550 mg/m2 allowed by the FDA, so further advancement of the US study must be discussed with the
FDA and a meeting for this purpose is expected to occur during the first half of 2020. Once we establish an RP2D in the European trial, the intent is to advance to a Phase 2 arm
planned  to  assess  the  safety  and  efficacy  of Annamycin  in  21  additional  patients.  We  may  amend  the  protocol  of  either  or  both  studies  where  appropriate  to  adapt  to  new
information  that  may  affect  patient  safety  and  care.  The  data  reported  is  preliminary  as  collected  by  independent  CRO  site  monitors  per  standard  practice  and  is  subject  to
subsequent quality assurance review.

We have been and intend to continue reporting top-line results by cohort in each trial, with each announcement also including an update on the other trial. Top-line
results  will  include  reporting  of  any  drug-related  adverse  events  (AEs)  and  assessment  of  cardiotoxicity,  including  ECHO  (echocardiogram)  or  MUGA  (MUGA  stands  for
multiple-gated acquisition and is also known as radionuclide ventriculography (RVG, RNV) or radionuclide angiography (RNA); it is a type of nuclear imaging test intended to
show how well the heart is pumping) scans measuring change in ejection fraction and measuring blood troponin level, which is considered a biomarker for potential long-term
cardiovascular impairment. Top-line results will also include the number of partial responses (PRs), complete responses (CRs) and patients deemed capable of progressing to a
potentially curative bone marrow transplant, which we term "bridge to transplant" (BTs), each of which is essentially a function of the magnitude of reduction in a patient's
bone marrow blasts. For purposes of these clinical trials, a CR means that the patient's bone marrow blasts reduced to 5% or less (with CRi meaning a CR where there was
incomplete recovery of white blood cell and/or platelet counts), a PR means the patient's bone marrow blasts reduced by 50% and resulted in a blast count of 25% or less, and a
BT means patients are deemed capable of progressing to a potentially curative bone marrow transplant.

The US trial also differs from the European trial in that the FDA would like to review safety data relating to cardiotoxicity from patients treated prior to advancing
beyond 120 mg/m2, as exceeding this dose level would require the patient to exceed the established lifetime maximum exposure to anthracyclines (presuming all anthracyclines
are cardiotoxic). We believe that the additional patient safety data gained from the European trial may also assist in the FDA's review of Annamycin's cardiac safety. We plan to
discuss with the FDA and EMA our intent to conduct a single arm Phase 2 trial. Our goal is for this trial serve as the basis for accelerated approval of Annamycin in AML and
for the FDA to allow us to rely on our European trial to establish a recommended Phase 2 dose. We can provide no assurance that the FDA will permit such reliance and we may
be required to conduct additional trials.

Safety of Annamycin in AML Patients -

Our US Phase 1 trial met its primary endpoint, demonstrating the safety of Annamycin in treating AML when delivered to patients at or below the lifetime maximum
anthracycline dose established by the FDA. The primary safety signal was the absence of cardiotoxicity, a serious and often treatment-limiting issue prevalent with currently
approved  anthracyclines. As  discussed  above,  this  was  determined  by  echocardiograms,  as  well  as  cardiac  health  biomarkers,  principally  blood  troponin  levels,  which  are
considered an indicator of potential long-term heart damage. The data showed no cardiotoxicity in all of the patients evaluated in the US Phase 1 trial.

Additionally,  there  were  no  unexpected  serious  adverse  events  and  no  dose  limiting  toxicities  at  any  dose  tested.  In  February  2020,  this  was  confirmed  by  an
independent  assessment  of  the  absence  of  cardiotoxicity  in  the  first  14  patients  treated  with Annamycin  in  both  our  US  and  European  Phase  1  clinical  trials  in  which  an
independent expert concluded that he "does not see evidence of cardiotoxicity.”

Compared  to  previous  studies  of  other  anthracyclines,  we  believe  this  is  an  important  event.  For  example,  a  recent  review  published  in  Cardiovascular  Drugs  and
Therapy (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5346598/) reported that 65% of patients who received the equivalent of 550 mg/m2 of doxorubicin (a current standard
of care anthracycline) exhibited sub-clinical cardiotoxicity, defined as a reduction in left ventricular ejection fraction >10% points to a value <50%. In the 5 patients mentioned
above who were treated in our European trial above 550 mg/m2, no evidence of cardiotoxicity was detected. The same published review also suggested that a better long-term
indicator  of  cardiotoxicity  may  be  the  measurement  of  an  increase  in  a  biomarker  called  troponin.  When  measured  as  an  early  biomarker  of  cancer  therapy-related
cardiotoxicity,  troponin  rise  occurs  consistently  in  21%  -  40%  of  patients  after  treatment  with  current  standard  of  care  anthracycline  chemotherapy  and,  per  the  published
review, such an increase in troponin is associated with an increased risk of heart disease later in life. Overall, some form of cardiotoxicity, short-term or long-term, occurs in
65% of such patients. Of the 17 patients treated thus far in both of our Annamycin clinical trials, none has shown an increase in troponin levels, again supporting the absence of
cardiotoxicity.

Preliminary Evidence of Effectiveness -

Although  the  primary  objective  of  the  US  Phase  1  trial  was  to  evaluate  safety,  the  study  also  gathered  data  to  support  a  preliminary  assessment  of Annamycin's
potential efficacy. Among other things, the study recorded complete response (CR), partial response (PR), and event-free survival. Based on these criteria, efficacy was seen in 2
or 30% of the US patients, even though the drug was dosed at what we considered to be sub-therapeutic levels. The evidence of efficacy consisted of 1 patient who achieved a
"morphologically leukemia-free state," which the protocol defined as a CR with incomplete recovery of platelets or neutrophils (CRi), and another patient who had a substantial
remission of leukemia cutis (a somewhat rare leukemia symptom), improving from diffuse to 3 small lesions.

We  believe  to  see  this  kind  of  activity  this  early  is  encouraging,  especially  since  Phase  1  trials  are  primarily  designed  to  demonstrate  safety,  not  efficacy,  and  the
dosing was therefore at a level we expected to be sub-therapeutic, based on previous data. We are also encouraged because Annamycin is being studied as a single agent, not in
combination with any other drugs. We believe this is potentially significant, because we believe the vast majority of relapsed or refractory AML patients do not respond to single
agents. Although this is very early data from a small sample size, we are especially encouraged because the dosing was well below our anticipated recommended Phase 2 dose.
We believe that, if the level of activity experienced in the US trial can be demonstrated in a larger patient population, we may be well-positioned to seek accelerated approval
from the FDA. FDA has granted Fast Track designation, which recognizes that Annamycin shows the potential to address unmet medical needs, which can include providing
efficacy comparable to available therapies while avoiding toxicity associated with the existing treatment.

Between the US and European studies, 14 AML patients have been evaluated after receiving Annamycin at or above 120 mg/m2. When they entered the study, 9 of the
14 patients were considered relapsed and 5 were considered refractory. Although reduction in bone and circulating blasts has been seen in both relapsed and refractory AML
patients, each of the 5

8

patients where efficacy endpoints were met was a relapsed patient. In the 14 patients mentioned, efficacy signals have been demonstrated to date in 55% of the relapsed and
36% of all patients after receiving Annamycin at or above 120 mg/m 2. The efficacy-related data for those patients (which includes the 2 US patients mentioned above) is as
follows:

•
•
•
•

One patient had a CRi, which the protocol defined as a complete response with incomplete recovery of white blood cells and/or platelets;
Two patients had PRs (partial responses, meaning that bone marrow blasts were reduced 50% and to below 25%);
One patient had a substantial remission of their somewhat rare leukemic symptom known as leukemia cutis; and
One patient was bridged to bone marrow transplant (BT) based on a sufficient reduction in bone marrow blasts.

We refer to Annamycin as a "next generation anthracycline," because it is designed, and thus far has shown clinically, to provide enhanced therapeutic benefits when
compared  with  traditional  anthracyclines  (like  doxorubicin)  while  reducing  the  potential  for  cardiotoxicity,  or  damage  to  the  heart.  This  design  intent  has  previously  been
validated with preclinical toxicology studies in animal models (as required by FDA) demonstrating Annamycin has little to no cardiotoxicity when compared with doxorubicin.
Of the 17 patients treated and fully evaluated thus far in both trials, including those treated below 120 mg/m2, none has shown any evidence of cardiotoxicity. This includes 9
patients in Europe who were treated at levels above the US maximum allowable lifetime cumulative anthracycline dose level (550 mg/m2), a limitation not imposed on our trial
in  Europe.  If  this  continues  to  be  confirmed  in  further  studies,  this  lack  of  toxicity  could  be  an  important  differentiator  between Annamycin  and  the  currently  approved
anthracyclines, for which cardiotoxicity is a well-known treatment limitation.

Plans for a Phase 2 Trial -

We intend to discuss with the FDA and EMA our plans to conduct a single arm Phase 2 trial that would serve as the basis for accelerated approval of Annamycin to
treat AML. This will follow the establishment of a RP2D in our ongoing Phase 1/2 dose escalation trial in Europe. The FDA has already granted Annamycin Fast Track status
and ODD for AML. The benefits of Fast Track include FDA actions to expedite development and review, including "rolling review," where the agency reviews portions of a
marketing application before the complete application is submitted.

Most  recently,  the  US  Phase  1  study  met  its  primary  objective  of  demonstrating  the  safety  of Annamycin  at  a  dose  that  was  cumulatively  at  or  below  the  lifetime
maximum anthracycline dose established by the FDA. Those results are consistent with results achieved with the parallel Phase 1/2 study being conducted in Europe, which has
demonstrated the safety of escalating doses of Annamycin in AML patients, including doses that significantly exceed the maximum lifetime dose of anthracyclines imposed in
the US. In both trials, the primary endpoints are aimed at demonstrating the product's safety, primarily the lack of cardiovascular risk.

Based on these results, we will continue to focus our efforts on the European trial to establish an RP2D. Once that is complete, we intend to enter discussions with the
FDA and EMA about conducting a single arm Phase 2 study that would be the pivotal trial supporting US and European approval of Annamycin for relapsed or refractory
AML. We can provide no assurance that the FDA or their EU or other equivalent will permit such reliance and we may be required to conduct additional trials.

Potential for the Treatment of Lung Metastasis with Annamycin

In April 2019, we announced that our ongoing sponsored research at The University of Texas MD Anderson Cancer Center demonstrated that Annamycin is able to
significantly  improve  survival  in  an  aggressive  form  of  triple  negative  breast  cancer  metastasized  to  the  lungs  in  animal  models.  We  know  that Annamycin  was  previously
shown to be significantly more potent than doxorubicin in both Lewis lung carcinoma in vivo and small cell lung cancer in vitro models. In addition to seeing significant activity
against animal models of triple negative breast cancer metastasized to the lungs, we are also seeing similar results in colon cancer metastasized to the lungs. The particular
animal models used in our testing are considered to represent a very aggressive forms of cancer. We believe our success in increasing the survival rate in mice with these tumor
models in combination with the previously observed high uptake of Annamycin by the lungs is a promising indication that supports additional clinical research in lung and
metastatic lung cancers.

In October 2019, we announced the expansion of Annamycin to large-scale production to supply the above-mentioned AML clinical trials, as they continue, and a trial
for the treatment of lung localized tumors. Our sponsored research at MD Anderson has demonstrated efficacy in lung metastases in different tumor animal models. The latest
research has demonstrated that, in animal models, Annamycin accumulates in the lungs at 5- to 6-fold higher concentrations than doxorubicin, the current standard of care for
lung metastases. We are now working with MD Anderson to design clinical trials to explore this potential.

Furthermore, a poster was presented entitled, "Liposomal annamycin inhibition of lung localized breast cancer," at the San Antonio Breast Cancer Symposium held in
December  2019.  The  published  poster  (https://www.moleculin.com/san-antonio-bc-symposium-poster/)  shows  substantially  increased  survival  in  both  triple  negative  breast
cancer and colon cancer

9

lung metastases animal models. It should also be noted that treatment with Annamycin resulted in long-term survival of a significant number of animals, even when cancer was
reintroduced  into  the  animals  post  initial  treatment,  suggesting  the  development  of  beneficial  immune  memory. A  reduction  in  tumor  growth  was  demonstrated  and  also  a
reversal of tumor activity resulting in an almost complete reduction of tumor burden.

The WP1066 Portfolio

We have a license agreement with MD Anderson pursuant to which we have been granted a royalty-bearing, worldwide, exclusive license for the patent and technology
rights related to our WP1066 Portfolio and its close analogs, molecules targeting the modulation of key oncogenic transcription factors. In 2019, the FDA granted ODD for
WP1066 for the treatment of glioblastoma, which means the agency believes we have established a medically plausible basis for expecting the drug to be effective.

Our WP1066 Portfolio (including lead drug candidates WP1066, WP1220 and WP1732), we believe,  represents  a  novel  class  of  agents  capable  of  hitting  multiple

targets, including the activated form of a key oncogenic transcription factor, STAT3. A substantial body of published research has identified STAT3 as a master regulator of a
wide range of tumors and has linked the activated form, p-STAT3, with the survival and progression of these tumors. For this reason, it is believed that targeted inhibition of p-
STAT3 may be an effective way to reduce or eliminate the progression of these diseases.

The high level of anticancer activity demonstrated in multiple tumors in animal models by WP1066 and WP1732 is potentially related to their ability to also inhibit
such important key oncogenic transcription factors like c-Myc and HIF-1α. In addition to direct anticancer effects not related to the function of the immune system, our lead
drug candidate WP1066 has also been shown to boost immune response in animals, in part by inhibiting activity of Regulatory T cells (TRegs), which are coopted by tumors to
evade the immune system. We believe the dual effect of (1) directly inhibiting tumor growth and inducing tumor cell death and (2) separately boosting and directing the natural
immune response to tumors is therapeutically promising. If additional preclinical and clinical data validate these two avenues of apparent activity, this class of drugs may be
well-suited to treat a wide range of tumors, both as single agents and as critical elements of successful combination therapies targeting even some of the most difficult-to-treat
cancers.

The recent oncology drug landscape has been dominated by immunotherapy, specifically including checkpoint inhibitors. In just the last 5 years, checkpoint inhibitors
(such as Opdivo and Keytruda) have reached over $10 billion in annual revenues. To summarize checkpoint blockade therapy, the T-Cells within an individual’s own immune
systems should be capable of identifying tumor cells and destroying them before they destroy the individual. Unfortunately, tumors develop the ability to prevent this natural
immune response by regulating the expression of certain receptors referred to as “immune checkpoints” that then bind to T-Cells and prevent them from attacking the tumor.
Immune checkpoint inhibitors are antibodies that block these receptor mechanisms and allow the T-Cells to act normally and attack the tumor.

In certain types of tumors, like melanoma, checkpoint inhibitors work well, and the results can be impressive, creating durable suppression of tumors where no other
therapy had succeeded. However, despite the outstanding results in select patients, checkpoint inhibitors benefit only a limited number of patients in certain cancers, and they
are essentially not effective in what are called “non-responsive” tumors like glioblastoma and pancreatic cancer, among others. As a result, companies are now focusing heavily
on combination therapies, combining immune checkpoint inhibitors with chemotherapy, as well as other agents. We believe there is a need for new chemotherapeutic agents
that,  by  their  specific  mechanism  of  action,  would  produce  potent  combination  effects  with  immune  checkpoint  inhibitors,  and  that  additionally  can  boost  immune  system
response on their own. In this regard, there is early preclinical evidence that WP1066, as a single agent, may have the ability to reverse immune tolerance in brain tumor patients
(Cancer Res, 67(20), 9630, 2007), and preliminary data in animal models that suggests WP1066 may have a potential for combination use with checkpoint inhibitors.

Recently  published  research  papers  have  presented  several  findings  that  may  point  to  major  new  opportunities  for  our  WP1066  class  of  drugs.  One  such  article
suggested that our STAT3 inhibitor WP1066 abrogated PD-L1/2 expression in cancer cells and may be a useful agent in addition to checkpoint inhibitor immunotherapy in
cancer patients (J Clin Exp Hematop, 57(1), 21-25, 2017). Other published results show  that  CTLA4-induced  immune  suppression  occurs  primarily  via  an  intrinsic  STAT3
pathway, suggesting that, through its inhibition of activated STAT3, WP1066 might work well in combination with this checkpoint inhibitor (Cancer Res, 77(18), 5118–28,
2017).

A separate paper presents selected key transcription factors as being responsible for the upregulation of an often-targeted checkpoint actor in tumors known as PD-L1.
Some of the most important transcription factors identified were HIF-1α, c-Myc and STAT3, the very targets for which WP1066 was designed (Front Pharmacol, 2018 May 22,
9:536, doi: 10.3389/ fphar.2018.00536, eCollection 2018). In summary, although much of the data is preclinical and all of it is preliminary, we are

10

optimistic that administration of WP1066 could lead to improved treatment results in many patients receiving checkpoint inhibitor therapy.

WP1066

WP1066 is our flagship Immune/Transcription Modulator. It has been the subject of over 50 peer-reviewed articles and its activity against p-STAT3 has now been
validated in independent labs around the globe. This discovery was inspired by a naturally occurring compound (caffeic acid) in propolis (from honeybees). Caffeic acid has
shown a natural ability to inhibit p-STAT3, which is considered a master regulator of inflammatory processes that support tumor survival and proliferation.

WP1066 has exhibited an ability to inhibit other key oncogenic transcription factors, including c-Myc and HIF-1α. A critical characteristic of WP1066 and its analogs
is the ability to inhibit p-STAT3 independently of upstream cell signaling. We believe this overcomes the limitations of many other drugs designed to inhibit STAT3 activity by
blocking upstream receptors.

Another important attribute of WP1066 (unlike some of our other Immune/Transcription Modulators) is its apparent ability in pre-clinical testing to cross the blood

brain barrier, which we believe makes it a good candidate for potentially treating brain tumors and other malignancies of the central nervous system.

WP1066 has shown significant anti-tumor activity and increased survival in a wide range of tumor cell lines and animal models.

As with other analogs in this portfolio, WP1066 also has a demonstrated in animal models the ability to boost a natural immune response to tumor activity. In animal
models, WP1066 has been shown to upregulate STAT1, a transcription factor associated with immune stimulation. At the same time, it has been shown to reduce levels of
Regulatory T-Cells, or TRegs, which are coopted by tumors to protect themselves from attack by the patient’s natural immune system. This forms a unique dual action (directly
attacking the transcription factors that support tumor development and separately boosting the natural immune response to tumors) that may make WP1066 uniquely suited to
treat a wide range of tumors and may also serve as an important element in combination therapies targeting some of the most difficult cancers.

In vitro testing has shown a high level of activity for WP1066 against a wide range of solid tumors, and in vivo testing has shown significant activity against head and
neck, pancreatic, stomach, and renal cancers, as well as metastatic melanoma and glioblastoma, among others. In vivo testing in mouse tumor models indicates that WP1066
inhibits tumor growth, blocks angiogenesis (a process that leads to the formation of blood vasculature needed for tumor growth) and increases survival.

Recently,  our  own  sponsored  research  and  published  findings  from  independent  researchers  point  to  the  possibility  that  administration  of  WP1066  could  lead  to
improved treatment results in many patients receiving checkpoint inhibitor therapy. Additionally, in April 2019 we announced that preclinical data supporting activity of our
STAT3-inhibiting  Immune/Transcription  Modulators  was  presented  by  Dr.  Waldemar  Priebe,  our  founder  and  chair  of  our  Scientific Advisory  Board,  at  the  2019 Annual
Meeting  of  the  American  Association  for  Cancer  Research  ("AACR")  in  Atlanta,  GA.  The  abstract  (AACR  Abstract:  https://www.moleculin.com/inhibition-of-stat3-in-
pancreatic-ductal-adenocarcinoma-and-immunotherapeutic-implications/  )  and presentation included data resulting from preclinical evaluation in pancreatic cancer models of
STAT3 inhibitors WP1066 and WP1732. In vitro efficacy of both inhibitors was assessed using proliferation and apoptosis induction assays in a panel of patient-derived and
commercially available Pancreatic Ductal Adenocarcinoma ("PDAC") cell lines. Both WP1066 and WP1732 were similarly potent and shown to induce apoptosis and inhibit p-
STAT3 and its nuclear localization in all tested PDAC cell lines. Observed IC50 values ranged from 0.5 to 2 μM. WP1732 was well tolerated by mice (LD50 85 mg/kg given
IV). Pharmacokinetic and biodistribution studies revealed very high uptake of WP1732 in the pancreas of mice and rats exceeding up to ~30 fold more than the drug levels in
plasma. Importantly, both agents show in-vivo efficacy in preliminary experiments when tested alone or in combination with T cell immune checkpoint inhibitors.

Clinical Activity WP1066 -

A physician-sponsored IND for a Phase I trial of WP1066 in patients with recurrent malignant glioma and brain metastasis from melanoma was allowed by the FDA in
December  2017.  In  July  2018,  this  trial  opened  for  recruitment  in  the  US.  This  dose-escalation  Phase  I  brain  tumor  clinical  trial  via  an  investigator-initiated  IND  with  MD
Anderson Cancer Center has generated pharmacokinetic data for oral dosed WP1066. That data demonstrated sufficient bioavailability of our drug via oral administration to
show the presence of WP1066 in blood plasma on a dose-dependent basis. Investigators at MD Anderson are now in the midst of the 4th dose escalation cohort in this trial. At
an annual meeting of the Society for Neuro Oncology (SNO), Emory University researchers reported encouraging activity in animals with their in vitro pediatric brain tumor
models using WP1066. Based on this data, they have filed and received clearance to proceed with an IND for a trial to treat children with recurrent or refractory malignant brain
tumors  with  WP1066.  This  trial  will  be  conducted  at  the Aflac  Cancer  &  Blood  Disorders  Center  at  Children's  Healthcare  of Atlanta.  This  trial  is  pending  finalization  of
Emory's internal administrative

11

documents and procedures. Although we can provide no assurance regarding the likelihood and timing of such trial, we expect the first patient to be treated in the first half of
2020.

The Phase 1 trial at MD Anderson with WP1066 drug is being supported by $2 million in private grant funding which is in addition to two Specialized Programs of
Research  Excellence  or  (SPORE)  peer  reviewed  grants  awarded  by  the  National  Cancer  Institute.  We  believe  the  rigorous  peer-review  process  applied  to  SPORE  grant
applications represents an important additional measure of independent assessment and validation of the research connected with our approach to using WP1066/STAT3 for the
treatment  of  cancer.  The  grants  described  here  do  not  flow  through  our  financial  statements,  but  instead  are  applied  to  the  cost  of  preclinical  and  clinical  activities  at  and
conducted by MD Anderson.

WP1220

An analog of WP1066, referred to as WP1220, was previously the subject of an IND (WP1220 was referred to as “MOL4239” for purposes of this IND) related to use
of the molecule in the topical treatment of psoriasis. Clinical trials were commenced on WP1220 in the US but were terminated early due to limited efficacy in the topical
treatment of psoriatic plaques. Notwithstanding its limitations in treating psoriasis, our pre-clinical research in multiple cutaneous T-cell lymphoma (“CTCL”) cell lines has
suggested that WP1220 may be effective in inhibiting CTCL. Based on this data, we are collaborating with two Polish drug development companies. One is Dermin, which has
received  previously  Polish  government  grant  money  to  develop  WP1220  in  Poland  for  the  topical  treatment  of  early  stage  CTCL  patients,  and  the  other  is  WPD
Pharmaceuticals, which is applying for Polish government grant money. CTCL is a potentially deadly form of skin cancer for which there are limited treatment options.

On  March  16,  2020,  we  entered  into  a  material  transfer  agreement  with  The  University  of  Texas  Medical  Branch  at  Galveston,  d/b/a  UTMB  Health  ("UTMB"),  a
health institution of The University of Texas System ("System"), an agency of the State of Texas (the "Agreement"). Pursuant to the Agreement, we agreed to provide research
material(s)  to  UTMB.  The  materials  will  be  used  by  UTMB  to  conduct  research,  specifically  to  test  the  effects  of  2  Deoxy  D-Glucose  (2DG)  and  analogues  thereof  on  the
infectivity of viruses, including Coronoavirus. The materials to be provided pursuant to the Agreement are subject to patent and technology license agreements we have with MD
Anderson  Cancer  Center.  In  the  event  that  use  of  the  materials  results  in  an  invention,  improvement,  substance,  or  information,  whether  or  not  patentable,  and  patent
applications and patents, if any, which result therefrom (the "Developed Technology"), UTMB has agreed to disclose such Developed Technology, in confidence, to us. At our
expense, we have the right to file for and obtain patent protection in the name of UTMB, if solely invented by UTMB, or in the name of both parties if jointly invented, for
Developed Technology or request UTMB to do so. Any Developed Technology conceived, invented, expressed and/or reduced to practice solely by UTMB in accordance with
UTMB’s research shall be solely owned by UTMB. For those inventions determined to be solely owned by UTMB, we have been granted an option to negotiate a license in
such  Developed  Technology  on  a  worldwide,  exclusive  basis  the  terms  of  which  shall  be  negotiated  by  and  between  the  parties  in  good  faith. Any  Developed  Technology
conceived, invented, expressed and/or reduced to practice jointly by UTMB and us in accordance with the research performed hereunder shall be deemed Jointly Developed
Technology and shall be owned jointly us and UTMB.

Clinical Activity WP1220 –

In August 2019, we completed full enrollment in a proof-of-concept clinical trial in Poland to study WP1220 for the treatment of CTCL. Polish authorities approved
our CTA for this use in January 2019, and the trial began enrolling patients in March 2019. In February 2020, we announced the final data from our CTCL clinical trial of
WP1220, which was published and presented by Dr. M. Sokolowska-Wojdylo in conjunction with the 4th Annual World Congress of Cutaneous Lymphomas in Barcelona,
Spain on February 13, 2020. The final results supported the safety of topical WP1220 and demonstrated a median improvement in the Composite Assessment of Index Lesion
Severity ("CAILS") score of 56% in treated (index) lesions for patients completing the study. We plan to meet with the FDA and EMA to discuss a Phase 2 Trial with WP1220
for the treatment of CTCL.

Mycosis Fungoides or MF, the most common variant of CTCL, is a disease with symptomatic, disfiguring skin lesions. STAT3, an oncogenic transcription factor, has
been identified as a critical regulator of MF, whereby the activation of STAT3 through phosphorylation (p-STAT3) has been linked to tumor proliferation and suppression of
immune responses. Preclinical testing demonstrated that WP1220, a synthetic compound, potently inhibits the activity of p-STAT3 and the growth of CTCL cell lines. This
Phase 1 study was designed to demonstrate the safety and efficacy of WP1220 after topical treatment of CTCL.

Of 5 subjects enrolled, 9 lesions were assessed according to the CAILS scoring system. The only adverse event (AE) was mild contact dermatitis in one subject felt not
to be related to the drug. 4 of the 5 subjects improved in CAILS scores on index lesions, with a median reduction of 56% (range 25-94%). Improvement was noted within 7 days
of treatment initiation and maintained 1 month after discontinuation. Independent dermatologic review based on photographic documentation was conducted and corroborated
these findings.

WP1220, an inhibitor of p-STAT3, demonstrated safety and efficacy in MF after topical treatment. We believe this is the first demonstration in humans suggesting that

inhibition of p-STAT3 with topical therapy has efficacy in CTCL. A larger Phase 2 study is now being planned.

IV Formulation for the WP1066 Portfolio

Currently WP1066 is dosed orally. WP1220 is topically applied. In February 2018, we announced that, pursuant to our continued collaboration with MD Anderson we
had developed and licensed WP1732, a new molecule in the WP1066 portfolio, in our effort to develop a new cancer treatment that effectively targets highly resistant tumors.
We believe this new discovery could improve our ability to treat a broader range of the most difficult cancers, and especially pancreatic cancer. Specifically, we have preclinical
evidence to suggest this new molecule is capable of the same level of immune stimulation and inhibition of oncogenic transcription factors (including p-STAT3) as WP1066.

WP1732  not  only  appears  to  share  the  same  key  mechanistic  properties  with  WP1066,  it  has  markedly  different  organ  distribution  and  we  believe  its  significantly
increased solubility may make it well suitable for administration via standard intravenous (IV) injection. In addition, preclinical testing has also shown that, while WP1732 does
not appear to cross the blood brain barrier, it appears to accumulate disproportionately in the pancreas, making it a potentially promising candidate for treating pancreatic cancer,
one of the most resistant and deadly forms of cancer.

We have begun planning and performing the necessary preclinical work to develop an IV formula for WP1066 and WP1732. This data is required to submit an IND or
its foreign equivalent for an intravenous formulation of WP1066. We expect to submit an IND in 2021. We are working with  The  University  of  Iowa  Pharmaceuticals  and
developers in Poland to develop an IV formulation.

The WP1122 Portfolio

We have a license agreement with MD Anderson pursuant to which we have been granted a royalty-bearing, worldwide, exclusive license for the patent and technology

rights related to our WP1122 Portfolio and similar molecules focused on inhibitors of glycolysis and glycosylation.

We believe this technology has the potential to target a wide variety of solid tumors, which eventually become resistant to all treatments, and thereby provide a large
and  important  opportunity  for  novel  drugs.  Notwithstanding  this  potential,  we  are  currently  focused  on  the  use  of  WP1122  and  related  analogs  for  the  treatment  of  central
nervous  system  malignancies  and  especially  glioblastoma  multiforme. Although  less  prevalent  than  some  larger  categories  of  solid  tumors,  cancers  of  the  central  nervous
system are particularly aggressive and resistant to treatment. The prognosis for such patients can be particularly grim and the treatment options available to their physicians are
among the most limited of any cancer.

The American Cancer Society has estimated 23,890 new cases of brain and other nervous system cancers will occur in the United States in 2020, resulting in 18,020

deaths. Despite the severity and poor prognosis of these tumors, there are few FDA-approved drugs on the market.

Overview of The Market for Our Oncology Drugs

Cancer is the second leading cause of death in the United States behind heart disease. In 2016, an estimated 15.5 million people in the United States were living with a
past or current diagnosis of cancer and, the American Cancer Society estimates that in 2020, nearly 1.8 million new cases will be diagnosed and over 600,000 Americans will
die from cancer.

Digestive,  reproductive,  breast  and  respiratory  cancers  comprise  58%  of  expected  cancer  diagnoses  in  2020,  while  cancers  like  leukemia  and  brain  tumors  are
considered  “rare  diseases.”  Leukemia  in  particular,  can  be  divided  into  acute,  chronic  and  other,  with  acute  lymphoblastic  leukemia  (ALL)  and  acute  myeloid  leukemia
(“AML”) comprising 19,940 of the estimated 60,530 new cases expected in the United States in 2020.

The worldwide cancer drug business has been estimated to represent approximately $100 billion in annual sales. Our lead drug candidate, Annamycin, is in a class of
drugs referred to as anthracyclines, which are chemotherapy drugs designed to destroy the DNA of targeted cancer cells. The approved anthracyclines most commonly used are
daunorubicin and doxorubicin and, prior to the expansion of their generic equivalents, annual revenues generated from anthracyclines have been estimated in the range of $600
million. Acute leukemia is one of a number of cancers that are treated with anthracyclines. One industry report estimates that annual drug revenues generated from the demand
for AML-related therapies in the United States, United Kingdom, France, Germany, Italy and Spain were in the range of $153 million in 2016, and it is estimated that this
number is

13

increasing with the increase in approved AML treatments. Of this worldwide amount, 67% is estimated to be attributed to the US market.

Our other two active development projects have applications (among others) in the treatment of brain tumors, another rare disease for which there are few available
treatments.  The  leading  brain  tumor  drug  is  temozolomide,  a  drug  introduced  under  the  brand  name  Temodar.  In  2012,  one  industry  source  reported  annual  revenues  of
approximately $882 million for Temodar before the expiration of its patent protection, at which point generic versions of the drug began to enter the market and reduce prices.

The Orphan Drug Act and other legislative initiatives provide incentives, including market exclusivity and accelerated approval pathways, for companies that pursue
the  development  of  treatments  for  rare  diseases  and  serious  diseases  for  which  there  are  few  or  no  acceptable  available  treatment  alternatives.  Over  the  last  10  years,  an
increasing  number  of  companies  have  begun  using  these  designations  to  obtain  new  drug  approvals  for  drugs  where  patent  coverage  has  expired  and/or  where  accelerated
approval appears possible. An IMS Health report estimated that, in 2013, the sale of drugs with full or partial Orphan Drug exclusivity represented approximately $29 billion in
revenue. We consider obtaining Orphan Drug exclusivity and accelerated approval to be an important part of our development strategy for our drug candidates. Notwithstanding
these  potential  opportunities,  we  can  provide  no  assurance  that  our  drugs  will  receive  Orphan  Drug  designation  (other  than Annamycin  and  WP1066,  both  of  which  have
received such designation) or, if approved, exclusivity or any other special designation that could, among other things, provide for accelerated approval.

Market for Annamycin

Leukemia is a cancer of the white blood cells and acute forms of leukemia can manifest quickly and leave patients with limited treatment options. AML is the most
common type of acute leukemia in adults. It occurs when a clone of leukemic progenitor white blood cells proliferates in the bone marrow, suppressing the production of normal
blood cells. Currently, the only viable option for acute leukemia patients is a bone marrow transplant, also known as a hematopoietic stem cell transplant, which is successful in
a significant number of patients. However, in order to qualify for a bone marrow transplant, the patient’s leukemia cells must be decreased to a sufficiently low level. This
usually  begins  with  a  therapy  referred  to  as  “7+3,”  which  consists  of  combining  seven  injections  of  Cytarbine  with  3  infusions  of  an  anthracycline  to  induce  remission  (a
complete response, or “CR”). This therapy had not improved since it was first used in the 1970s and we estimate that this induction therapy had a success rate of about 20% to
25%. A revision to this therapy was approved in the form of a drug called Vyxeos, which involves combining Cytarabine and an anthracycline (daunorubicin) into a single
liposomal  injection  given  3  times.  This  improvement  appears  to  have  increased  the  level  of  CRs  to  34%  and  the  overall  survival  by  3.5  months.  Unfortunately,  the  current
clinically approved anthracyclines (including Vyxeos) are cardiotoxic (i.e., can damage the heart), which can limit the dosage amount that may be administered to patients.
Additionally, the tumor cells often present de novo or develop resistance to the first line anthracycline, through what is called “multidrug resistance,” enabling the tumor cells to
purge themselves of the available anthracyclines. Consequently, there remains no effective therapy for inducing remission in the majority of these patients sufficient to enable a
potentially  curative  bone  marrow  transplant  and  unfortunately  most  patients  will  succumb  quickly  to  their  leukemia.  If  a  patient’s  leukemia  reappears  before  they  can  be
prepared for a bone marrow transplant, they are considered to have “relapsed.” If a patient fails to achieve a sufficient response from the induction therapy to qualify for a bone
marrow transplant, they are considered to be “refractory” (resistant to therapy). Together, this group of relapsed and refractory AML patients constitutes our primary focus for
treatment with Annamycin and our intent is to pursue FDA approval for Annamycin as a second-line induction therapy for adult relapsed or refractory AML patients.

We believe that pursuing approval as a second line induction therapy for adult relapsed or refractory AML patients is the shortest path to regulatory approval, but we
also believe that one of the most important potential uses of Annamycin is in the treatment of children with either AML or ALL (acute lymphoblastic leukemia, which is more
common in children). Accordingly, we also intend to pursue approval for pediatric use in these conditions when practicable.

Our License Agreements

Sponsored Research and License Agreements with MD Anderson

We license all of our technology from MD Anderson and we also sponsor research there as well. Under license agreements associated with Annamycin, the WP1122
Portfolio, and the WP1066 Portfolio, which includes WP1732, all described below, we are responsible for certain license, milestone and royalty payments over the course of the
agreements. Annual  license  fees,  prior  to  the  first  sale  of  a  licensed  product,  can  be  as  high  as  $0.1  million  depending  upon  the  anniversary.  Milestone  payments  for  the
commencement of phase II and phase III clinical trials can cost as high as $0.5 million. Other milestone payments for submission of an NDA to the FDA and receipt of first
marketing approval for sale of a license product can be as high as $0.6 million. Royalty payments can range in the single digits as a percent of net sales on drug products or flat
fees as high as $0.6 million, depending upon certain terms and conditions. Not all of these payments are applicable to every

14

drug. Total expenses under these agreements were $0.2 million and $0.3 million for the year ended December 31, 2019 and 2018, respectively.

We have a sponsored research agreement with MD Anderson that currently runs until the end of October 2021. The expenses recognized under the MD Anderson

agreement with regards to the sponsored research agreement were $0.5 million and $0.4 million for the year ended December 31, 2019 and 2018, respectively.

Annamycin

On June 29, 2017, we entered into an agreement with MD Anderson licensing certain technology related to the method of preparing Liposomal Annamycin. The terms

and payments of which are included in the summary above.

WP1066 Portfolio

The rights and obligations to a June 2010 Patent and Technology License Agreement entered into by and between Moleculin LLC and MD Anderson (the “Moleculin
Agreement”)  have  been  assigned  to  us.  Therefore,  we  have  obtained  a  royalty-bearing,  worldwide,  exclusive  license  to  intellectual  property  rights,  including  patent  rights,
related to our WP1066 drug product candidate. In consideration, we must make payments to MD Anderson including an up-front payment, milestone payments and minimum
annual royalty payments for sales of products developed under the license agreement. Annual maintenance fee payments will no longer be due upon marketing approval in any
country of a licensed product. One-time milestone payments are due upon commencement of the first Phase III study for a licensed product within the United States, Europe,
China or Japan; upon submission of the first NDA for a licensed product in the United States; and upon receipt of the first marketing approval for sale of a licensed product in
the United States. The rights we have obtained pursuant to the assignment of the Moleculin Agreement are made subject to the rights of the US government to the extent that the
technology covered by the licensed intellectual property was developed under a funding agreement between MD Anderson and the US government. The terms and payments of
which are included in the summary above.

In February 2018, we entered into a license agreement covering a new group of molecules recently discovered in connection with research we have been sponsoring at

MD Anderson Cancer Center called WP1732, a part of the WP1066 Portfolio. The terms and payments of which are included in the summary above.

WP1122 Portfolio

The  rights  and  obligations  to  an April  2012  Patent  and  Technology  License Agreement  entered  into  by  and  between  IntertechBio  and  MD Anderson  have  been
assigned to us. Therefore, we have obtained a royalty-bearing, worldwide, exclusive license to intellectual property, including patent rights, related to our WP1122 Portfolio and
to our drug product candidate, WP1122. The terms and payments of which are included in the summary above.

WPD Licensing Agreement

On February 19, 2019, we sublicensed certain intellectual property rights, including rights to Annamycin, our WP1122 portfolio, and our WP1066 portfolio to WPD
Pharmaceuticals (“WPD”) (the “WPD Agreement”). WPD is affiliated with Dr. Waldemar Priebe, our founder and largest shareholder. Under the WPD Agreement, we granted
WPD a royalty-bearing, exclusive license to research, develop, manufacture, have manufactured, use, import, offer to sell and/or sell products in the field of human therapeutics
under the licensed intellectual property in the countries of Germany, Poland, Estonia, Latvia, Lithuania, Belarus, Ukraine, Moldova, Romania, Armenia, Azerbaijan, Georgia,
Slovakia,  Czech  Republic,  Hungary,  Uzbekistan,  Kazakhstan,  Greece, Austria,  Russia,  Netherlands,  Turkey,  Belgium,  Switzerland,  Sweden,  Portugal,  Norway,  Denmark,
Ireland, Finland, Luxembourg, Iceland (“licensed territories”), provided that we have the right to buyback Germany from the licensed territories by making a payment of $0.5
million. On July 30, 2019, we entered into an agreement that satisfied the foregoing buyback right, and as such, Germany is no longer considered part of the licensed territories.

In consideration for entering into the WPD Agreement, WPD agreed that it must use Commercially Reasonable Development Efforts to develop and commercialize
products in the licensed territories. For purposes of the WPD Agreement, the term “Commercially Reasonable Development Efforts” means the expenditure by or on behalf of
WPD  or  any  of  its  affiliates  of  at  least:  (i)  $2.0  million  during  the  first  two  years  of  the  agreement  on  the  research,  development  and  commercialization  of  products  in  the
licensed territories; and (ii) $1.0 million annually for the two years thereafter on the research and development of products in the licensed territories.

In  addition,  within  sixty  days  we  agreed  to  transfer  to  WPD  certain  development  data,  and,  in  exchange  for  such  development  data,  WPD  agreed  to  make  a
development  reimbursement  fee  to  us  in  the  amount  of  $0.3  million  (the  “Development  Reimbursement  Fee”)  within  the  first  year  of  the  agreement.  WPD  did  not  pay the
Development

15

Reimbursement Fee, so the Commercially Reasonable Development Efforts during the first two years of the agreement increased from $2.0 million to $2.5 million.

During the term of the WPD Agreement, to the extent we are required to make any payments to MD Anderson pursuant to our license agreements with MD Anderson,
whether a milestone or royalty payment, as a result of the research and development or sale of a sublicensed product, WPD shall be required to advance or reimburse us such
payments. In further consideration for the rights granted by us to WPD under the WPD Agreement, WPD agreed to pay us a royalty percentage at a rate equal to the royalty rate
we  owe  MD Anderson  under  our  license  agreements  with  MD Anderson  plus  an  additional  royalty  (the  “override  royalty  percentage”)  equal  to  1.0%  of  net  sales  of  any
sublicensed products, provided, however, if WPD spends: (i) more than $5.0 million in Commercially Reasonable Development Efforts prior to the fifth anniversary of the date
of the agreement and more than $6.0 million in Commercially Reasonable Development Efforts prior to the sixth anniversary of the date of the agreement, the override royalty
percentage will decrease to 0.75% of net sales; or (ii) more than $6.0 million in Commercially Reasonable Development Efforts prior to the fifth anniversary of the date of the
agreement  and  more  than  $8.0  million  in  Commercially  Reasonable  Development  Efforts  prior  to  the  sixth  anniversary  of  the  date  of  the  agreement,  the  override  royalty
percentage will decrease to 0.5% of net sales.

With certain exceptions, the WPD Agreement will remain in full force and effect until the expiration of the last patent within the sublicensed patents. Notwithstanding
the  foregoing,  we  have  the  right,  in  our  sole  discretion,  to  terminate  the  WPD Agreement  in  whole,  or  to  materially  amend  the  agreement  by  removing  a  portion  of  the
sublicensed subject matter, in connection with certain fundamental transactions or in connection with the granting to an unaffiliated third party of a license or sublicense to all or
to a material portion of the sublicensed subject matter within all or substantially all of the licensed territories (such event, the “buyback event”) by making a payment to WPD
equal  to  a  percentage  of  the  consideration  after  transaction  costs  we  receive  in  connection  with  the  buyback  event.  The  percentage  payable  will  be  the  greater  of:  (i)  2%
increasing to 5% upon the completion by WPD of its initial public offering, provided such offering provides WPD with net proceeds of not less than $2.0 million; or (ii) 10%
multiplied by a fraction (A) the numerator of which is the total dollar amount of expenditures made by WPD that represent Commercially Reasonable Development Efforts
under the WPD Agreement, up to a maximum of $2.0 million; and (B) the denominator of which is $2.0 million.

Prior  to  approval  of  the  WPD  Agreement,  our  board  of  directors  received  a  fairness  opinion  from  Roth  Capital  Partners,  LLC  stating  their  opinion  that  the

consideration we will receive from WPD pursuant to the WPD Agreement is fair, from a financial point of view, to us.

Animal Life Sciences Licensing Agreement

On February 19, 2019, we sublicensed certain intellectual property rights, including rights to Annamycin, our WP1122 portfolio, and our WP1066 portfolio in the field
of non-human animals to Animal Life Sciences, LLC (“ALI”) (the “ALI Agreement”). ALI is affiliated with Dr. Waldemar Priebe, our founder and largest shareholder. Under
the ALI Agreement, we granted ALI a worldwide royalty-bearing, exclusive license to research, develop, manufacture, have manufactured, use, import, offer to sell and/or sell
products in the field of non-human animals under the licensed intellectual property. This license is subject to the terms in the prior agreements entered into by the Company and
MDA. ALI granted us the right to name an observer to ALI's board of directors. On August 8, 2019, the Company named its Chairman and CEO Walter V. Klemp to that
position.

During the term of the ALI Agreement, to the extent we are required to make any payments to MD Anderson pursuant to our license agreements with MD Anderson,
whether a milestone or royalty payment, as a result of the research and development or sale of a sublicensed product, ALI shall be required to advance or reimburse us such
payments. In further consideration for the rights granted by us to ALI under the ALI Agreement, ALI agreed to pay us a royalty percentage at a rate equal to the royalty rate we
owe  MD  Anderson  under  our  license  agreements  with  MD  Anderson  plus  an  additional  royalty  equal  to  5.0%  of  net  sales  of  any  sublicensed  products.  As  additional
consideration, ALI issued us a 10% ownership interest in ALI.

With certain exceptions, the ALI Agreement will remain in full force and effect until the expiration of the last patent within the sublicensed patents.

Other Licenses

In  2015,  we  obtained  the  rights  and  obligations  for  certain  patent  and  technology  development  and  license  agreements  with  Dermin  sp.  z  o.o.  (“Dermin”).  In
connection  with  such  agreements,  certain  intellectual  property  rights  related  to Annamycin,  our  WP1122  portfolio,  and  our  WP1066  portfolio  were  licensed  to  Dermin  and
Dermin was granted a royalty-bearing, exclusive license to manufacture, have manufactured, use, import, offer to sell and/or sell products in the field of human therapeutics
under the licensed intellectual property. With respect to Annamycin, the license is limited to the countries

16

of Poland, Ukraine, Czech Republic, Hungary, Romania, Slovakia, Belarus, Lithuania, Latvia, Estonia, Netherlands, Turkey, Belgium, Switzerland, Austria, Sweden, Greece,
Portugal, Norway, Denmark, Ireland, Finland, Luxembourg, Iceland, Kazakhstan, Russian Federation, Uzbekistan, Georgia, Armenia, Azerbaijan and Germany; provided that
we had the right to remove Germany from the list of covered territories with a $0.5 million payment. With respect to WP1122, the license is limited to the countries of Belarus,
Russia, Kazakhstan, Uzbekistan, Turkmenistan, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia and Ukraine. With respect to WP1066, the
license is limited to the countries of Belarus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia and Ukraine. In each case, Dermin agreed to pay
a royalty for the sale of any licensed product in the licensed territories and agreed to pay all out-of-pocket expenses incurred in filing, prosecuting and maintaining the licensed
patents for which the license has been granted in the licensed territories. Dermin also agreed to provide a percentage of certain consideration that Dermin receives pursuant to
sublicense agreements. In July 2019, Dermin assigned its rights under the foregoing license agreements to an affiliated entity, Exploration Invest Pte Ltd. (“Exploration”). On
July 30, 2019, we and Exploration entered into a License Modification Agreement pursuant to which we agreed to issue Exploration shares of Company common stock valued
at  $0.5  million  (based  on  the  greater  of  the  closing  price  of  the  common  stock  on  the  date  of  the  agreement  or  the  10-day  average  closing  price  prior  to  the  date  of  the
agreement) in exchange for the modifying the license agreements to: (i) limit the licensed territory solely to Poland; and (ii) limit the patent rights and technology rights licensed
to Exploration to the patent rights and technology rights that existed on the date the original license agreements were entered into with Dermin. On August 8, 2019, we issued
429,978 shares of common stock to Exploration to satisfy this commitment.

Corporate History

We  were  founded  in  2015  by  Walter  Klemp  (our  chairman  and  CEO),  Dr.  Don  Picker  (our  Chief  Science  Officer)  and  Dr.  Waldemar  Priebe  of  MD Anderson
(Chairman of our Scientific Advisory Board) in order to combine and consolidate the development efforts involving several oncology technologies, based on license agreements
with MD Anderson. Dr. Priebe is a Professor of Medicinal Chemistry in the Department of Experimental Therapeutics, Division of Cancer Medicine, at the University of Texas
MD Anderson Cancer Center. This effort began with the acquisition of the Annamycin development project from AnnaMed, Inc. followed by the acquisition of the license rights
to the WP1122 Portfolio from IntertechBio Corporation. Further, on behalf of Moleculin, LLC, we entered into a co-development agreement with Houston Pharmaceuticals,
Inc., which culminated with the merger of Moleculin, LLC into MBI coincident with our initial public offering allowing us to gain control of the WP1066 Portfolio.

In  June  2018,  we  formed  Moleculin Australia  Pty.  Ltd.,  a  wholly  owned  subsidiary  to  oversee  pre-clinical  development  in Australia.  The Australian  government
provides an aggressive incentive for research and development carried out in their country. We believe having an Australian subsidiary could provide a great opportunity for
quality, pre-clinical development and reduce the overall cost of our continued drug development efforts.

Competition

We  operate  in  a  highly  competitive  segment  of  the  pharmaceutical  market,  which  market  is  highly  competitive  as  a  whole.  We  face  competition  from  numerous
sources including commercial pharmaceutical and biotechnology enterprises, academic institutions, government agencies, and private and public research institutions. Many of
our competitors may have significantly greater financial, product development, manufacturing and marketing resources. Additionally, many universities and private and public
research institutes are active in cancer research, and some may be in direct competition with us. We may also compete with these organizations to recruit scientists and clinical
development  personnel.  Smaller  or  early-stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through  collaborative  arrangements  with  large  and
established companies.

The unmet medical need for more effective cancer therapies is such that oncology drugs are one of the leading class of drugs in development. These include a wide
array of products against cancer targeting many of the same indications as our drug candidates. While the introduction of newer targeted agents may result in extended overall
survival, induction therapy regimens are likely to remain a cornerstone of cancer treatment in the foreseeable future.

There are a number of established therapies that may be considered competitive for the cancer indications for which we intend to develop our lead product candidate,
Annamycin. A key consideration when treating AML patients is whether the patient is suitable for intensive therapy. The standard of care for the treatment of newly diagnosed
AML  patients  who  can  tolerate  intensive  therapy  is  cytarabine  in  combination  with  an  anthracycline  (e.g.,  doxorubicin  or  daunorubicin),  typically  referred  to  as  a  “7+3”
regimen. For some patients, primarily those less than 60 years of age, a stem cell transplant could also be considered if the induction regimen is effective in attaining a CR
(Complete  Response).  The  7+3  regimen  of  cytarabine  in  combination  with  an  anthracycline  has  been  the  standard  of  care  for  decades. A  patient  not  suitable  for  intensive
therapy may be offered the option for low-intensity therapy such as low-dose cytarabine, azacitidine or decitabine. It should be noted that, in the United States, these are not
approved by the FDA for the treatment of AML patients and there remains no effective therapy for

17

these patients or for relapsed or refractory AML, with the exception of some recently approved targeted therapies that have demonstrated a low level of activity for limited
subgroups of AML patients. The initial focus for Annamycin development is in patients for whom the standard induction regimen has failed. Also, several major pharmaceutical
companies and biotechnology companies are aggressively pursuing new cancer development programs for the treatment of AML.

A number of attempts have been made or are under way to provide an improved treatment for AML. Celator Pharmaceuticals reported Phase III clinical trial results for
a new combined formulation of cytarabine and daunorubicin (commonly used induction therapy drugs) they call Vyxeos. This new liposome formulation provides a 5:1 ratio of
cytarabine and daunorubicin in each of three injections. When compared with patients receiving 7 injections of cytarabine and 3 injections of daunorubicin (traditional 7+3
induction therapy), patients receiving Vyxeos achieved an average increase in overall survival of approximately 3.5 months (9.5 months compared with 6 months). Despite this
extension of overall survival, Vyxeos did not reduce the toxic side effects of daunorubicin (including cardiotoxicity) and it failed to qualify a majority of patients for curative
bone marrow transplant. With these results, Jazz Pharmaceuticals acquired Celator in 2016 and obtained FDA approval, making Vyxeos the new first line standard of care for
the treatment of AML

Drugs attempting to target a subset of AML patients who present with specific gene mutations, such as one referred to as FLT3, have recently received FDA approval,
but by definition serve only subsets of the AML population. Other targeted therapies are currently in clinical trials, as well as other approaches that include immunotherapy
relying  on  other  biomarkers,  other  attempts  at  improved  chemotherapy  and  alternative  approaches  to  radiation  therapy.  Other  approaches  to  improve  the  effectiveness  of
induction therapy are in early stage clinical trials and, although they do not appear to address the underlying problems with anthracyclines, we can provide no assurance that
such improvements, if achieved, would not adversely impact the need for improved anthracyclines. A modified version of doxorubicin designed to reduce cardiotoxicity is in
clinical  trials  for  the  treatment  of  sarcoma  and,  although  this  drug  does  not  appear  to  address  multidrug  resistance  and  is  not  currently  intended  for  the  treatment  of  acute
leukemia, we can provide no assurance that it will not become a competitive alternative to Annamycin. Although we are not aware of any other single agent therapies in clinical
trials that would directly compete against Annamycin in the treatment of relapsed and refractory AML, we can provide no assurance that such therapies are not in development,
will not receive regulatory approval and will reach market before our drug candidate Annamycin. In addition, any such competing therapy may be more effective and/or cost-
effective than ours.

Government Regulation

Government  authorities  in  the  US,  at  the  federal,  state  and  local  level,  and  in  other  countries  extensively  regulate,  among  other  things,  the  research,  development,
testing,  manufacture,  quality  control,  approval,  labeling,  packaging,  storage,  record-keeping,  promotion,  advertising,  distribution,  post-approval  monitoring  and  reporting,
marketing and export and import of products such as those we are developing. The pharmaceutical drug product candidates that we develop must be approved by the FDA
before they may be marketed and distributed.

In  the  United  States,  the  FDA  regulates  pharmaceutical  products  under  the  Federal  Food,  Drug,  and  Cosmetic Act,  and  implementing  regulations.  Pharmaceutical
products are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate
federal,  state,  local  and  foreign  statutes  and  regulations  require  the  expenditure  of  substantial  time  and  financial  resources.  Failure  to  comply  with  the  applicable  US
requirements at any time during the product development process, approval process or after approval, may subject an applicant to administrative or judicial sanctions. FDA and
related enforcement activity could include refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures,
total or partial suspension of production or distribution injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties. Any agency
or  judicial  enforcement  action  could  have  a  material  adverse  effect  on  us.  The  process  required  by  the  FDA  before  a  pharmaceutical  product  may  be  marketed  in  the  US
generally involves the following:

•

•

•

•

•

Completion of preclinical laboratory tests, animal studies and formulation studies according to Good Laboratory Practices and in accordance with the Animal Welfare
Act or other applicable regulations;

Submission to the FDA of an Investigational New Drug application, or IND, which must become effective before human clinical studies may begin;

Performance of adequate and well-controlled human clinical studies according to the FDA’s current good clinical practices (“GCP”), to establish the safety and efficacy
of the proposed pharmaceutical product for its intended use;

Submission to the FDA of an NDA for a new pharmaceutical product;

Satisfactory completion of an FDA inspection of the manufacturing facility or facilities where the pharmaceutical product is produced, to assess compliance with current
good manufacturing practices (“cGMP”), to assure that the

18

facilities, methods and controls are adequate to preserve the pharmaceutical product’s identity, strength, quality and purity;

Potential FDA audit of the preclinical and clinical study sites that generated the data in support of the NDA; and

FDA review and approval of the NDA.

•

•

The  lengthy  process  of  seeking  required  approvals  and  the  continuing  need  for  compliance  with  applicable  statutes  and  regulations  require  the  expenditure  of

substantial resources and approvals, and continued compliance are inherently uncertain.

Before testing any compounds with potential therapeutic value in humans, the pharmaceutical product candidate enters the preclinical testing stage. Preclinical tests
include laboratory evaluations of product chemistry, toxicity and formulation, as well as animal studies to assess the potential safety and activity of the pharmaceutical product
candidate. These early proof-of-principle studies are done using sound scientific procedures and thorough documentation. The conduct of the single and repeat dose toxicology
and toxicokinetic studies in animals must comply with federal regulations, laws and requirements including good laboratory practices. The sponsor must submit the results of
the preclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the
IND. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA has concerns and notifies the sponsor. In such a case, the IND sponsor and the
FDA must resolve any outstanding concerns before the clinical study can begin. If resolution cannot be reached within the 30-day review period, either the FDA places the IND
on clinical hold or the sponsor withdraws the application. The FDA may also impose clinical holds on a pharmaceutical product candidate at any time before or during clinical
studies for various reasons. Accordingly, we cannot be sure that submission of an IND will result in the FDA allowing clinical studies to begin, or that, once begun, issues will
not arise that suspend or terminate such clinical study.

Clinical studies involve the administration of the pharmaceutical product candidate to healthy volunteers or patients under the supervision of qualified investigators,
generally physicians not employed by or under the clinical study sponsor’s control. Clinical studies are conducted under protocols detailing, among other things, the objectives
of the clinical study, dosing procedures, subject selection and exclusion criteria, how the results will be analyzed and presented and the parameters to be used to monitor subject
safety.  Each  protocol  must  be  submitted  to  the  FDA  as  part  of  the  IND.  Clinical  studies  must  be  conducted  in  accordance  with  GCP.  Further,  each  clinical  study  must  be
reviewed and approved by an independent institutional review board (“IRB”) at, or servicing, each institution at which the clinical study will be conducted. An IRB is charged
with protecting the welfare and rights of study participants and considers such items as whether the risks to individuals participating in the clinical studies are minimized and are
reasonable  in  relation  to  anticipated  benefits.  The  IRB  also  approves  the  informed  consent  form  that  must  be  provided  to  each  clinical  study  subject  or  his  or  her  legal
representative and must monitor the clinical study until completed.

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

•

•

•

Phase 1: The pharmaceutical product is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and
excretion.  In  the  case  of  some  products  for  severe  or  life-threatening  diseases  such  as  cancer,  especially  when  the  product  may  be  too  inherently  toxic  to  ethically
administer to healthy volunteers, the initial human testing is often conducted in patients, with a goal of characterizing the safety profile of the drug and establishing a
maximum  tolerable  dose  (“MTD”).  Our  pharmaceutical  products  fall  into  this  latter  category  because  its  products  are  intended  to  treat  cancer  and  contain  cytotoxic
agents. Hence, our Phase 1 studies are conducted in late-stage cancer patients whose disease has progressed after treatment with other agents.

Phase 2: With the maximum tolerable dose established in a Phase 1 trial, the pharmaceutical product is evaluated in a limited patient population at the MTD to identify
possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases, to determine dosage tolerance, optimal dosage
and dosing schedule and to identify patient populations with specific characteristics where the pharmaceutical product may be more effective.

Phase 3: Clinical studies are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical
study sites. These clinical studies are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for product labeling. The studies
must be well controlled and usually include a control arm for comparison. One or two Phase 3 studies are usually required by the FDA for an NDA approval, depending
on  the  disease  severity  and  other  available  treatment  options.  In  some  instances,  an  NDA  approval  may  be  obtained  based  on  Phase  2  clinical  data  with  the
understanding that the approved drug can be sold subject to a confirmatory trial to be conducted post-approval.

19

•

Post-approval studies, or Phase 4 clinical studies, may be conducted after initial marketing approval. These studies are often used to gain additional experience from the
treatment of patients in the intended therapeutic indication. The FDA also may require Phase 4 studies, Risk Evaluation and Mitigation Strategies (“REMS”) and post-
marketing surveillance, among other things, to monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or use of
the product.

Progress reports detailing the results of the clinical studies must be submitted at least annually to the FDA and written IND safety reports must be submitted to the
FDA and the investigators for serious and unexpected adverse events or any finding from tests in laboratory animals that suggests a significant risk for human subjects. Phase 1,
Phase 2 and Phase 3 clinical studies may not be completed successfully within any specified period, if at all. The FDA or the sponsor or its data safety monitoring board may
suspend a clinical study at any time on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an
IRB  can  suspend  or  terminate  approval  of  a  clinical  study  at  its  institution  if  the  clinical  study  is  not  being  conducted  in  accordance  with  the  IRB’s  requirements  or  if  the
pharmaceutical product has been associated with unexpected serious harm to patients.

Concurrent with clinical studies, companies may complete additional animal studies and must also develop additional information about the chemistry and physical
characteristics of the pharmaceutical product 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 pharmaceutical product candidate and, among other things, must develop methods for
testing the identity, strength, quality and purity of the final pharmaceutical product. Additionally, appropriate packaging must be selected and tested, and stability studies must
be conducted to demonstrate that the pharmaceutical product candidate does not undergo unacceptable deterioration over its shelf life.

The results of product development, preclinical studies and clinical studies, along with descriptions of the manufacturing process, analytical tests conducted on the
chemistry  of  the  pharmaceutical  product,  proposed  labeling  and  other  relevant  information  are  submitted  to  the  FDA  as  part  of  an  NDA  requesting  approval  to  market  the
product. The submission of an NDA is subject to the payment of substantial user fees. A waiver of such fees may be obtained under certain limited circumstances.

The  FDA  reviews  all  NDAs  submitted  before  it  accepts  them  for  filing  and  may  request  additional  information  rather  than  accepting  an  NDA  for  filing.  Once  the
submission is accepted for filing, the FDA begins an in-depth review of the NDA. Under the goals and policies agreed to by the FDA under the Prescription Drug User Fee Act
(“PDUFA”), the FDA has 10 months after the 60-day filing date in which to complete its initial review of a standard review NDA and respond to the applicant, and six months
after the 60-day filing date for a priority review NDA. The FDA does not always meet its PDUFA goal dates for standard and priority NDAs.

After the NDA submission is accepted for filing, the FDA reviews the NDA application to determine, among other things, whether the proposed product is safe and
effective for its intended use, and whether the product is being manufactured in accordance with cGMP to assure and preserve the product’s identity, strength, quality and purity.
The FDA may refer applications for novel pharmaceutical products or pharmaceutical products which present difficult questions of safety or efficacy to an advisory committee,
typically  a  panel  that  includes  clinicians  and  other  experts,  for  review,  evaluation  and  a  recommendation  as  to  whether  the  application  should  be  approved  and  under  what
conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. During the
pharmaceutical product approval process, the FDA also will determine whether a risk evaluation and mitigation strategy (“REMS”) is necessary to assure the safe use of the
pharmaceutical product. If the FDA concludes that a REMS is needed, the sponsor of the NDA must submit a proposed REMS; the FDA will not approve the NDA without a
REMS, if required.

Before approving an NDA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the
manufacturing processes and facilities are in compliance with 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 as well as the site where the pharmaceutical product is manufactured to assure
compliance with GCP and cGMP. If the FDA determines the application, manufacturing process or manufacturing facilities are not acceptable, it will outline the deficiencies in
the submission and often will request additional testing or information. In addition, the FDA will require the review and approval of product labeling.

The NDA review and approval process is lengthy and difficult and the FDA may refuse to approve an NDA if the applicable regulatory criteria are not satisfied or may
require additional clinical data or other data and information. Even if such data and information is submitted, the FDA may ultimately decide that the NDA does not satisfy the
criteria for approval. Data obtained from clinical studies are not always conclusive and the FDA may interpret data differently than we interpret the same data. The FDA will
issue  a  complete  response  letter  if  the  agency  decides  not  to  approve  the  NDA.  The  complete  response  letter  usually  describes  all  of  the  specific  deficiencies  in  the  NDA
identified by the FDA. The deficiencies identified may be minor,

20

for  example,  requiring  labeling  changes,  or  major,  for  example,  requiring  additional  clinical  studies. Additionally,  the  complete  response  letter  may  include  recommended
actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the NDA,
addressing all of the deficiencies identified in the letter, or withdraw the application.

If  a  product  receives  regulatory  approval,  the  approval  may  be  significantly  limited  to  specific  diseases  and  dosages  or  the  indications  for  use  may  otherwise  be
limited,  which  could  restrict  the  commercial  value  of  the  product.  Further,  the  FDA  may  require  that  certain  contraindications,  warnings  or  precautions  be  included  in  the
product labeling. In addition, the FDA may require Phase 4 testing which involves clinical studies designed to further assess pharmaceutical product safety and effectiveness
and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized.

Expedited Development and Review Programs

The  FDA  has  a  Fast  Track  program  that  is  intended  to  expedite  or  facilitate  the  process  for  reviewing  new  pharmaceutical  products  that  meet  certain  criteria.
Specifically, new pharmaceutical products are eligible for Fast Track designation if they are intended to treat a serious condition and data demonstrate the potential to address
unmet medical needs for the condition. Fast Track designation applies to the combination of the product and the specific indication for which it is being studied. Unique to a
Fast Track product, the FDA may consider for review sections of the NDA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for
the submission of the sections of the NDA, if the FDA determines that the schedule is acceptable and if the sponsor pays any required user fees upon submission of the first
section of the NDA.

Any product submitted to the FDA for market, including a Fast Track program, may also be eligible for other FDA programs intended to expedite development and
review,  such  as  priority  review  and  accelerated  approval. Any  product  is  eligible  for  priority  review  if  it  is  intended  to  treat  a  serious  condition  and  it  offers  a  significant
improvement in safety or effectiveness compared to marketed products. The FDA will move more quickly in its review of such products in an effort to complete the review four
months  sooner  than  a  standard  review. Additionally,  accelerated  approval  may  be  available  for  a  product  intended  to  treat  a  serious  condition  that  provides  a  meaningful
therapeutic benefit over existing treatments, which means the product may be approved on the basis of clinical data establishing an effect on a surrogate endpoint or on an
intermediate  clinical  endpoint. As  a  condition  of  accelerated  approval,  the  FDA  may  require  the  sponsor  to  perform  adequate  and  well-controlled  post-marketing  clinical
studies.  In  addition,  the  FDA  currently  requires  pre-approval  of  promotional  materials  for  products  receiving  accelerated  approval,  which  could  impact  the  timing  of  the
commercial launch of the product. Fast Track designation, priority review and accelerated approval do not change the standards for approval but may expedite the development
or approval process.

Post-Approval Requirements

Any pharmaceutical products for which the Company receives FDA approvals are subject to continuing regulation by the FDA, including, among other things, cGMP
compliance, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling
and distribution requirements, complying with certain electronic records and signature requirements and complying with FDA promotion and advertising requirements, which
include  standards  for  direct-to-consumer  advertising,  prohibitions  on  promoting  pharmaceutical  products  for  uses  or  in  patient  populations  that  are  not  described  in  the
pharmaceutical product’s approved labeling (known as “off-label use”), industry-sponsored scientific and educational activities and promotional activities involving the internet.
Failure to comply with FDA requirements can have negative consequences, including adverse publicity, enforcement letters from the FDA, actions by the US Department of
Justice  and/or  US  Department  of  Health  and  Human  Services’  Office  of  Inspector  General,  mandated  corrective  advertising  or  communications  with  doctors,  and  civil  or
criminal  penalties. Although  physicians  may  prescribe  legally  available  pharmaceutical  products  for  off-label  uses,  manufacturers  may  not  directly  or  indirectly  market  or
promote such off-label uses.

We rely and expect to continue to rely on third parties for the production of clinical and commercial quantities of our products. Manufacturers of our products are
required to comply with applicable FDA manufacturing requirements contained in the FDA’s cGMP regulations. cGMP regulations require, among other things, quality control
and  quality  assurance,  as  well  as  the  corresponding  maintenance  of  records  and  documentation.  Pharmaceutical  product  manufacturers  and  other  entities  involved  in  the
manufacture  and  distribution  of  approved  pharmaceutical  products  are  required  to  register  their  establishments  with  the  FDA  and  certain  state  agencies  and  are  subject  to
periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time,
money and effort in the area of production and quality control to maintain cGMP compliance. Discovery of problems with a product after approval may result in restrictions on
a  product,  manufacturer  or  holder  of  an  approved  NDA,  including  withdrawal  of  the  product  from  the  market.  In  addition,  changes  to  the  manufacturing  process  generally
require prior FDA approval before being

21

implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and
approval.

Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of the FDA approval of the use of our pharmaceutical product candidates, some of our products covered by US
patents  may  be  eligible  for  limited  patent  term  extension  under  the  Drug  Price  Competition  and  Patent  Term  Restoration Act  of  1984,  commonly  referred  to  as  the  Hatch-
Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development
and the FDA regulatory review process for a product the approval of which is the first permitted commercial marketing of the active pharmaceutical ingredient. However, patent
term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-
half  the  time  between  the  effective  date  of  an  IND  and  the  submission  date  of  an  NDA  plus  the  time  between  the  submission  date  of  an  NDA  and  the  approval  of  that
application. Only one patent applicable to an approved pharmaceutical product is eligible for the extension and the application for the extension must be submitted prior to the
expiration of the patent unless an extension is obtained. The US Patent and Trademark Office, in consultation with the FDA, reviews and renders a decision on the application
for any patent term extension or restoration. In the future, we may be able to apply for extension of patent term for one or more of our currently licensed patents or any future
owned patents to add patent life beyond its current expiration date, depending upon the expected length of the clinical studies and other factors involved in the filing of the
relevant NDA.

Pharmaceutical Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any pharmaceutical product candidates for which we may obtain regulatory approval. In
the United States and in markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend in part upon the availability
of reimbursement from third-party payers. Third-party payers include government payers such as Medicare and Medicaid, managed care providers, private health insurers and
other organizations. The process for determining whether a payer will provide coverage for a pharmaceutical product may be separate from the process for setting the price or
reimbursement rate that the payer will pay for the pharmaceutical product. Third-party payers may limit coverage to specific pharmaceutical products on an approved list, or
formulary, which might not, and frequently do not, include all of the FDA-approved pharmaceutical products for a particular indication. Third-party payers are increasingly
challenging the price and examining the medical necessity and cost-effectiveness of medical products and services, in addition to their safety and efficacy. A payer’s decision to
provide coverage for a pharmaceutical product does not imply that an adequate reimbursement rate will be approved. Adequate third-party reimbursement may not be available
to enable us to maintain price levels sufficient to realize an appropriate return on our investment in product development. In addition, in the United States there is a growing
emphasis on comparative effectiveness research, both by private payers and by government agencies. We may need to conduct expensive pharmaco-economic studies in order to
demonstrate the medical necessity and cost-effectiveness of our products, in addition to the costs required to obtain the FDA approvals. Our pharmaceutical product candidates
may not be considered medically necessary or cost-effective. To the extent other drugs or therapies are found to be more effective than our products, payers may elect to cover
such therapies in lieu of our products and/or reimburse our products at a lower rate.

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

The  marketability  of  any  pharmaceutical  product  candidates  for  which  we  may  receive  regulatory  approval  for  commercial  sale  may  suffer  if  the  government  and
third-party  payers  fail  to  provide  adequate  coverage  and  reimbursement.  In  addition,  emphasis  on  managed  care  in  the  United  States  has  increased  and  we  expect  this  will
continue to increase the pressure on pharmaceutical pricing. 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  we  may  receive  regulatory  approval,  less  favorable  coverage  policies  and  reimbursement  rates  may  be
implemented in the future.

22

International Regulation

In addition to regulations in the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of
our future drugs. Whether or not we obtain FDA approval for a drug, we must obtain approval of a drug by the comparable regulatory authorities of foreign countries before we
can commence clinical trials or marketing of the drug in those countries. The approval process varies from country to country, and the time may be longer or shorter than that
required for FDA approval. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary greatly from country to country.

Under European Union regulatory systems, marketing authorizations may be submitted either under a centralized or mutual recognition procedure. The centralized
procedure provides for the grant of a single marketing authorization that is valid for all European Union member states. The mutual recognition procedure provides for mutual
recognition of national approval decisions. Under this procedure, the holder of a national marketing authorization may submit an application to the remaining member states.
Within 90 days of receiving the applications and assessment report, each member state must decide whether to recognize approval.

In addition to regulations in Europe and the United States, we will be subject to a variety of foreign regulations governing clinical trials and commercial distribution of

our future drugs.

Employees

As  of  December  31,  2019,  we  had  eleven  full-time  employees  and  five  part-time  employees,  and  accordingly,  a  high  percentage  of  the  work  performed  for  our

development projects is outsourced to qualified independent contractors.

Legal Proceedings

We are not subject to any litigation.

ITEM 1A. RISK FACTORS

The following risks and uncertainties should be carefully considered. If any of the following occurs, our business, financial condition or operating results could be
materially harmed. An investment in our securities is speculative in nature, involves a high degree of risk and should not be made by an investor who cannot bear the economic
risk of its investment for an indefinite period of time and who cannot afford the loss of its entire investment.

Risks Related to Regulatory Approval and the Development and Commercialization of our Drug Candidates

We are developing our drugs to treat patients who are extremely or terminally ill, and patient deaths that occur in our clinical trials could negatively impact our business
even if such deaths are not shown to be related to our drugs.

It is our intention to continue to develop our drug candidates focused on rare and deadly forms of cancer. Patients suffering from these diseases are extremely sick and
have  a  high  likelihood  of  experiencing  adverse  outcomes,  including  death,  as  a  result  of  their  disease  or  due  to  other  significant  risks  including  relapse  of  their  underlying
malignancies. Many patients have already received high-dose chemotherapy and/or radiation therapy, which are associated with their own inherent risks, prior to treatment with
our drugs.

As a result, it is likely that we will observe severe adverse outcomes during our clinical trials for our drugs, including patient death. If a significant number of study
subject  deaths  were  to  occur,  regardless  of  whether  such  deaths  are  attributable  to  one  of  our  drugs,  our  ability  to  obtain  regulatory  approval  and/or  achieve  commercial
acceptance for the related drug may be adversely impacted and our business could be materially harmed. 

We are conducting important clinical trials in Poland, preclinical work in Australia, and studies for additional countries in which to perform preclinical studies and clinical
trials and the risks associated with conducting research and clinical trials abroad could materially adversely affect our business.

We  have  approved  Clinical  Trial Authorizations  in  Poland  for  two  clinical  trials. Additionally,  we  are  performing  substantial  preclinical  studies  via  our Australian

subsidiary. Furthermore, we are performing studies to determine if there are additional countries in which we should hold clinical and preclinical studies. Accordingly, we expect
that we will be subject to additional risks related to operating in foreign countries, including:

•

•

•

•

•

•

•

•

•

•

differing regulatory requirements in foreign countries;

unexpected changes in price and exchange controls and other regulatory requirements;

increased difficulties in managing the logistics and transportation of collecting and shipping patient material;

import and export requirements and restrictions;

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

foreign taxes, including withholding of payroll taxes;

foreign currency fluctuations, which could result in increased operating expenses, and other obligations incident to doing business in another country;

difficulties staffing and managing foreign operations;

potential liability under the Foreign Corrupt Practices Act of 1977 or comparable foreign regulations;

challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and protect intellectual property

rights to the same extent as the United States;

•

•

production shortages resulting from any events affecting raw material supply or manufacturing capabilities abroad; and

business interruptions resulting from geo-political actions, including war and terrorism.

24

 
 
These and other risks associated with our international operations may materially adversely affect our ability to attain or maintain profitable operations.

There are limited suppliers for active pharmaceutical ingredients (“API”) used in in our drug candidates. Problems with the third parties that manufacture the API used in
our drug candidates may delay our clinical trials or subject us to liability.

We  do  not  currently  own  or  operate  manufacturing  facilities  for  clinical  or  commercial  production  of  the API  used  in  any  of  our  product  candidates.  We  have  no
experience in API manufacturing, and we lack the resources and the capability to manufacture any of the APIs used in our product candidates, on either a clinical or commercial
scale. As a result, we rely on third parties to supply the API used in each of our product candidates. We expect to continue to depend on third parties to supply the API for our
current and future product candidates and to supply the API in commercial quantities. We are ultimately responsible for confirming that the APIs used in our product candidates
are manufactured in accordance with applicable regulations.

Our third-party suppliers may not carry out their contractual obligations or meet our deadlines. In addition, the API they supply to us may not meet our specifications
and quality policies and procedures or they may not be able to supply the API in commercial quantities. If we need to find alternative suppliers of the API used in any of our
product candidates, we may not be able to contract for such supplies on acceptable terms, if at all. Any such failure to supply or delay caused by such contract manufacturers
would have an adverse effect on our ability to continue clinical development of our product candidates or commercialization of our product candidates.

If  our  third-party  drug  suppliers  fail  to  achieve  and  maintain  high  manufacturing  standards  in  compliance  with  cGMP  regulations,  we  could  be  subject  to  certain

product liability claims in the event such failure to comply resulted in defective products that caused injury or harm.

We cannot be certain that any of our drug candidates will receive regulatory approval, and without regulatory approval we will not be able to market such drugs.

Our business currently depends on the successful development and commercialization of our drug candidates. Our ability to generate revenue related to product sales, if

ever, will depend on the successful development and regulatory approval of our drug candidates.

We currently have no products approved for sale and we cannot guarantee that we will ever have marketable products. The development of a product candidate and
issues relating to its approval and marketing are subject to extensive regulation by the FDA in the United States and regulatory authorities in other countries, with regulations
differing from country to country. We are not permitted to market our product candidates in the United States until we receive approval of a NDA from the FDA. We have not
submitted any marketing applications for any of our product candidates.

NDAs must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each desired
indication. NDAs must also include significant information regarding the chemistry, manufacturing and controls for the product. Obtaining approval of a NDA is a lengthy,
expensive and uncertain process, and we may not be successful in obtaining approval. The FDA review processes can take years to complete and approval is never guaranteed.
If we submit a NDA to the FDA, the FDA must decide whether to accept or reject the submission for filing. We cannot be certain that any submissions will be accepted for
filing and review by the FDA. Regulators in other jurisdictions have their own procedures for approval of product candidates. Even if a product is approved, the FDA may limit
the indications for which the product may be marketed, require extensive warnings on the product labeling or require expensive and time-consuming clinical trials or reporting
as conditions of approval. Regulatory authorities in countries outside of the United States and Europe also have requirements for approval of drug candidates with which we
must comply with prior to marketing in those countries. Obtaining regulatory approval for marketing of a product candidate in one country does not ensure that we will be able
to obtain regulatory approval in any other country. In addition, delays in approvals or rejections of marketing applications in the United States, Europe or other countries may
be based upon many factors, including regulatory requests for additional analyses, reports, data, preclinical studies and clinical trials, regulatory questions regarding different
interpretations  of  data  and  results,  changes  in  regulatory  policy  during  the  period  of  product  development  and  the  emergence  of  new  information  regarding  our  product
candidates or other products. Also, regulatory approval for any of our product candidates may be withdrawn.

If we are unable to obtain approval from the FDA, or other regulatory agencies, for any of our product candidates, or if, subsequent to approval, we are unable to

successfully commercialize our product candidates, we will not be able to generate sufficient revenue to become profitable or to continue our operations.

25

 
 
 
Any statements in this report indicating that any of our drug candidates have demonstrated preliminary evidence of efficacy are our own  and  are  not  based  on  the
FDA’s or any other comparable governmental agency’s assessment and do not indicate that such drug candidate will achieve favorable efficacy results in any later stage trials or
that the FDA or any comparable agency will ultimately determine that such drug candidate is effective for purposes of granting marketing approval.

Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval
for any of our product candidates.

Delays in the commencement, enrollment and completion of clinical trials could increase our product development costs or limit the regulatory approval of our product
candidates. We do not know whether any future trials or studies of our other product candidates will begin on time or will be completed on schedule, if at all. The start or end of
a clinical study is often delayed or halted due to changing regulatory requirements, manufacturing challenges, including delays or shortages in available drug product, required
clinical trial administrative actions, slower than anticipated patient enrollment, changing standards of care, availability or prevalence of use of a comparative drug or required
prior  therapy,  clinical  outcomes  or  financial  constraints.  For  instance,  delays  or  difficulties  in  patient  enrollment  or  difficulties  in  retaining  trial  participants  can  result  in
increased costs, longer development times or termination of a clinical trial. Clinical trials of a new product candidate require the enrollment of a sufficient number of patients,
including patients who are suffering from the disease the product candidate is intended to treat and who meet other eligibility criteria. Rates of patient enrollment are affected
by many factors, including the size of the patient population, the eligibility criteria for the clinical trial, that include the age and condition of the patients and the stage and
severity of disease, the nature of the protocol, the proximity of patients to clinical sites and the availability of effective treatments and/or availability of investigational treatment
options for the relevant disease.

A  product  candidate  can  unexpectedly  fail  at  any  stage  of  preclinical  and  clinical  development.  The  historical  failure  rate  for  product  candidates  is  high  due  to
scientific feasibility, safety, efficacy, changing standards of medical care and other variables. The results from preclinical testing or early clinical trials of a product candidate
may  not  predict  the  results  that  will  be  obtained  in  later  phase  clinical  trials  of  the  product  candidate.  We,  the  FDA  or  other  applicable  regulatory  authorities  may  suspend
clinical  trials  of  a  product  candidate  at  any  time  for  various  reasons,  including,  but  not  limited  to,  a  belief  that  subjects  participating  in  such  trials  are  being  exposed  to
unacceptable health risks or adverse side effects, or other adverse initial experiences or findings. We may not have the financial resources to continue development of, or to
enter  into  collaborations  for,  a  product  candidate  if  we  experience  any  problems  or  other  unforeseen  events  that  delay  or  prevent  regulatory  approval  of,  or  our  ability  to
commercialize, product candidates, including:

•

•

inability to obtain sufficient funds required for a clinical trial;

inability to reach agreements on acceptable terms with prospective CROs and trial sites, the terms of which can be subject to extensive negotiation and may

vary significantly among different CROs and trial sites;

•

negative  or  inconclusive  results  from  our  clinical  trials  or  the  clinical  trials  of  others  for  product  candidates  similar  to  ours,  leading  to  a  decision  or

requirement to conduct additional preclinical testing or clinical trials or abandon a program;

•

•

•

•

•

•

•

serious and unexpected drug-related side effects experienced by subjects in our clinical trials or by individuals using drugs similar to our product candidates;

conditions imposed by the FDA or comparable foreign authorities regarding the scope or design of our clinical trials;

delays in enrolling research subjects in clinical trials;

high drop-out rates and high fail rates of research subjects;

inadequate supply or quality of product candidate components or materials or other supplies necessary for the conduct of our clinical trials;

greater than anticipated clinical trial costs;

poor effectiveness of our product candidates during clinical trials; or

26

 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

unfavorable FDA or other regulatory agency inspection and review of a clinical trial site or vendor.

We have commenced clinical trials and have never submitted an NDA, and any product candidate we advance through clinical trials may not have favorable results in
later clinical trials or receive regulatory approval.

Clinical  failure  can  occur  at  any  stage  of  our  clinical  development.  Clinical  trials  may  produce  negative  or  inconclusive  results,  and  our  collaborators  or  we  may
decide,  or  regulators  may  require  us,  to  conduct  additional  clinical  trials  or  nonclinical  studies.  In  addition,  data  obtained  from  trials  and  studies  are  susceptible  to  varying
interpretations, and regulators may not interpret our data as favorably as we do, which may delay, limit or prevent regulatory approval. Success in preclinical studies and early
clinical trials does not ensure that subsequent clinical trials will generate the same or similar results or otherwise provide adequate data to demonstrate the efficacy and safety of
a product candidate. A number of companies in the pharmaceutical industry, including those with greater resources and experience than us, have suffered significant setbacks in
clinical  trials,  even  after  seeing  promising  results  in  earlier  clinical  trials.  The  commencement  and  completion  of  future  clinical  studies  could  be  substantially  delayed  or
prevented by several factors, including, but not limited to:

•

•

•

•

a limited number of, and competition for, suitable patients with particular types of cancer for enrollment in our clinical studies;

delays or failures in reaching acceptable clinical study agreement terms;

failure of patients to complete the clinical study; and

unforeseen safety issues.

In addition, 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.  We  may  be  unable  to  design  and  execute  a  clinical  trial  to  support  regulatory  approval.  Further,  clinical  trials  of  potential
products often reveal that it is not practical or feasible to continue development efforts.

If  any  of  our  drug  product  candidates  are  found  to  be  unsafe  or  lack  efficacy,  we  will  not  be  able  to  obtain  regulatory  approval  for  it  and  our  business  would  be

harmed.

In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors,
including changes in trial protocols, differences in composition of the patient populations, adherence to the dosing regimen and other trial protocols and the rate of dropout
among clinical trial participants. We do not know whether any clinical trials we or any of our potential future collaborators may conduct will demonstrate the consistent or
adequate efficacy and safety that would be required to obtain regulatory approval and market any products. If we are unable to bring any of our drug candidates to market, or to
acquire other products that are on the market or can be developed, our ability to create long-term stockholder value will be limited.

Our product candidates may have undesirable side effects that may delay or prevent marketing approval, or, if approval is received, require them to be taken off the market,
require them to include safety warnings or otherwise limit their sales.

Unforeseen  side  effects  from  any  of  our  product  candidates  could  arise  either  during  clinical  development  or,  if  any  product  candidates  are  approved,  after  the
approved  product  has  been  marketed.  For  example,  in  the  most  recent  Phase  I/II  dose-ranging  clinical  trial  of Annamycin,  conducted  by  a  prior  developer,  two  patients
succumbed to tumor lysis syndrome (“TLS”) resulting from the debris created by Annamycin killing the targeted leukemic blasts more rapidly than their body’s ability to cope.
Now that this potential has been identified, prophylactic measures intended to protect patients from TLS will be deployed in future clinical trials, but there can be no assurance
that such measures will be effective or that other adverse events may not emerge related to our drug. As another example, we are currently conducting a Phase 1 trial to attempt
to increase the maximum tolerable dose (“MTD”) for Annamycin, however, unforeseen side effects could prevent us from increasing the MTD from the one established in the
prior  Phase  I/II  trial. Additional  or  unforeseen  side  effects  from Annamycin  or  any  of  our  other  product  candidates  could  arise  either  during  clinical  development  or,  if
approved, after the approved product has been marketed.

The  range  and  potential  severity  of  possible  side  effects  from  oncology  therapies  such  as  our  drug  candidates  are  significant.  If  any  of  our  drug  candidates  cause
undesirable or unacceptable side effects in the future, this could interrupt, delay or halt clinical trials and result in the failure to obtain or suspension or termination of marketing
approval from the FDA and other regulatory authorities or result in marketing approval from the FDA and other regulatory authorities only with restrictive label warnings or
other limitations.

27

 
 
 
 
 
 
 
If any of our product candidates receives marketing approval and we or others later identify undesirable or unacceptable side effects caused by such products:

product;

•

•

•

•

•

•

•

regulatory authorities may require the addition of labeling statements, specific warnings, a contraindication or field alerts to physicians and pharmacies;

we  may  be  required  to  change  instructions  regarding  the  way  the  product  is  administered,  conduct  additional  clinical  trials  or  change  the  labeling  of  the

we may be subject to limitations on how we may promote the product;

sales of the product may decrease significantly;

regulatory authorities may require us to take our approved product off the market;

we may be subject to litigation or product liability claims; and

our reputation may suffer.

Any  of  these  events  could  prevent  us  or  our  potential  future  collaborators  from  achieving  or  maintaining  market  acceptance  of  the  affected  product  or  could

substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues from the sale of our products. 

If the FDA does not find the manufacturing facilities of our future contract manufacturers acceptable for commercial production, we may not be able to commercialize
any of our product candidates.

We  do  not  intend  to  manufacture  the  pharmaceutical  products  that  we  plan  to  sell.  One  example  is  that  we  are  currently  utilizing  contract  manufacturers  for  the
production of the active pharmaceutical ingredients and the formulation of drug product for our trials of Annamycin that we will need to conduct prior to seeking regulatory
approval. However, we do not have agreements for supplies of Annamycin or any of our other product candidates and we may not be able to reach agreements with these or
other contract manufacturers for sufficient supplies to commercialize Annamycin if it is approved. Additionally, the facilities used by any contract manufacturer to manufacture
any of our product candidates must be the subject of a satisfactory inspection before the FDA approves the product candidate manufactured at that facility. We are completely
dependent  on  these  third-party  manufacturers  for  compliance  with  the  requirements  of  US  and  non-US  regulators  for  the  manufacture  of  our  finished  products.  If  our
manufacturers cannot successfully manufacture material that conform to our specifications and the FDA’s current good manufacturing practice standards, or cGMP, and other
requirements of any governmental agency whose jurisdiction to which we are subject, our product candidates will not be approved or, if already approved, may be subject to
recalls or other negative actions. Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured our product candidates, including: 

•

•

•

manufacturer.

the possibility that we are unable to enter into a manufacturing agreement with a third party to manufacture our product candidates;

the possible breach of the manufacturing agreements by the third parties because of factors beyond our control; and

the  possibility  of  termination  or  nonrenewal  of  the  agreements  by  the  third  parties  before  we  are  able  to  arrange  for  a  qualified  replacement  third-party

Any  of  these  factors  could  cause  the  delay  of  approval  or  commercialization  of  our  product  candidates,  cause  us  to  incur  higher  costs  or  prevent  us  from
commercializing  our  product  candidates  successfully.  Furthermore,  if  any  of  our  product  candidates  are  approved  and  contract  manufacturers  fail  to  deliver  the  required
commercial quantities of finished product on a timely basis at commercially reasonable prices and we are unable to find one or more replacement manufacturers capable of
production at a substantially equivalent cost, in substantially equivalent volumes and quality and on a timely basis, we would likely be unable to meet demand for our products
and could lose potential revenue. It may take several years to establish an alternative source of supply for our product candidates and to have any such new source approved by
the government agencies that regulate our products.

28

 
 
 
 
 
 
 
 
 
 
 
 
 
We received Orphan Drug designation for Annamycin and WP1066, but it may not effectively prevent approval of a competing product.

In 2017, we received notice that the FDA granted Orphan Drug designation ("ODD") for Annamycin for the treatment of AML. In February 2019, we received notice
that the FDA granted ODD for WP1066 for the treatment of glioblastoma. Moreover, even though Orphan Drug exclusivity was granted, we cannot know that it will prevent
approval of another product containing Annamycin and intended to treat AML or WP1066 and intended to treat glioblastoma, because any such subsequent product could be
demonstrated to be clinically superior to Annamycin or WP1066.

The  regulatory  approval  processes  of  the  FDA  and  comparable  foreign  authorities  are  lengthy,  time  consuming  and  inherently  unpredictable,  and  even  if  we  obtain
approval  for  a  product  candidate  in  one  country  or  jurisdiction,  we  may  never  obtain  approval  for  or  commercialize  it  in  any  other  jurisdiction,  which  would  limit  our
ability to realize our full market potential.

Prior to obtaining approval to commercialize a product candidate in any jurisdiction, we and our collaborators must demonstrate with substantial evidence from well
controlled clinical trials, and to the satisfaction of the FDA or comparable foreign regulatory agencies, that such product candidates are safe and effective for their intended uses.
Results from nonclinical studies and clinical trials can be interpreted in different ways. Even if we believe the nonclinical or clinical data for a product candidate are promising,
such data may not be sufficient to support approval by the FDA and other regulatory authorities. In order to market any products in any particular jurisdiction, we must establish
and comply with numerous and varying regulatory requirements on a country-by-country basis regarding safety and efficacy. Approval by the FDA does not ensure approval by
regulatory  authorities  in  any  other  country  or  jurisdiction  outside  the  United  States.  In  addition,  clinical  trials  conducted  in  one  country  may  not  be  accepted  by  regulatory
authorities in other countries, and regulatory approval in one country does not guarantee regulatory approval in any other country. Approval processes vary among countries and
can involve additional product testing and validation, as well as additional administrative review periods. Seeking regulatory approval could result in difficulties and costs for us
and require additional nonclinical studies or clinical trials, which could be costly and time consuming. Regulatory requirements can vary widely from country to country and
could delay or prevent the introduction of our products in those countries. We do not have any product candidates approved for sale in any jurisdiction, including in international
markets, and we do not have experience in obtaining regulatory approval. If we fail to comply with regulatory requirements in international markets or to obtain and maintain
required approvals, or if regulatory approvals in international markets are delayed, our target market will be reduced and our ability to realize the full market potential of any
product we develop will be unrealized.

We have received Fast Track designation for one of our product candidates and may seek the same designation for one of more of our other product candidates. Even if we
receive designation, such designation may not actually lead to a faster development or regulatory review or approval process.

If  a  product  is  intended  for  the  treatment  of  a  serious  condition  and  nonclinical  or  clinical  data  demonstrate  the  potential  to  address  unmet  medical  need  for  this
condition,  a  product  sponsor  may  apply  for  FDA  Fast  Track  designation.  If  we  seek  Fast  Track  designation  for  a  product  candidate,  we  may  not  receive  it  from  the  FDA.
However, even if we receive Fast Track designation, Fast Track designation does not ensure that we will receive marketing approval or that approval will be granted within any
particular  time  frame.  We  may  not  experience  a  faster  development  or  regulatory  review  or  approval  process  with  Fast  Track  designation  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.

Risks Related to our Intellectual Property

The composition of matter patent for Annamycin has expired, and other patents have not yet been issued, and may not be issued.

We are pursuing additional patents with claims directed to Annamycin drug product formulations and the methods of use of Annamycin to treat relapsed or refractory
AML and other conditions, and methods for its synthesis, as the composition of matter patent protection for Annamycin has expired. As a result, competitors may be able to
offer and sell products so long as these competitors do not infringe any other patents that third parties or we hold, including formulation, synthesis and method of use patents.
However, particularly with regard to products approved for more than one indication, method of use patents may not provide significant protection, because a competitor could
obtain  approval  for  only  a  non-protected  use  and  thus  come  to  market,  where  the  product  may  legally  be  prescribed  for  the  protected  use,  thus  undermining  the  protection
provided by the patent. Although off-label prescriptions may infringe our method of use patents, the practice is common across medical

29

specialties and such infringement is difficult to prevent or prosecute. Off-label sales would limit our ability to generate revenue from the sale of Annamycin, if approved for
commercial sale.

 The intellectual property rights we have licensed from MD Anderson are subject to the rights of the US government.

We have obtained a royalty-bearing, worldwide, exclusive license to intellectual property rights, including patent rights related to our WP1066 Portfolio and WP1122
Portfolio  drug  product  candidates  from  MD Anderson.  Some  of  our  licensed  intellectual  property  rights  from  MD Anderson  have  been  developed  in  the  course  of  research
funded by the US government. As a result, the US government may have certain rights to intellectual property embodied in our current or future products pursuant to the Bayh-
Dole Act of 1980. Government rights in certain inventions developed under a government-funded program include a non-exclusive, non-transferable, irrevocable worldwide
license to use inventions for any governmental purpose. In addition, the US government has the right to require us, or an assignee or exclusive licensee to such inventions, to
grant licenses to any of these inventions to a third party if they determine that: (i) adequate steps have not been taken to commercialize the invention; (ii) government action is
necessary to meet public health or safety needs; (iii) government action is necessary to meet requirements for public use under federal regulations; or (iv) the right to use or sell
such inventions is exclusively licensed to an entity within the US and substantially manufactured outside the US without the US government’s prior approval. Additionally, we
may  be  restricted  from  granting  exclusive  licenses  for  the  right  to  use  or  sell  our  inventions  created  pursuant  to  such  agreements  unless  the  licensee  agrees  to  additional
restrictions (e.g., manufacturing substantially all of the invention in the US). The US government also has the right to take title to these inventions if we fail to disclose the
invention to the government and fail to file an application to register the intellectual property within specified time limits. In addition, the U.S. government may acquire title in
any country in which a patent application is not filed within specified time limits. Additionally, certain inventions are subject to transfer restrictions during the term of these
agreements and for a period, thereafter, including sales of products or components, transfers to foreign subsidiaries for the purpose of the relevant agreements, and transfers to
certain foreign third parties. If any of our intellectual property becomes subject to any of the rights or remedies available to the US government or third parties pursuant to the
Bayh-Dole Act of 1980, this could impair the value of our intellectual property and could adversely affect our business. 

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights.

We may from time to time seek to enforce our intellectual property rights against infringers when we determine that a successful outcome is probable and may lead to
an increase in the value of the intellectual property. If we choose to enforce our patent rights against a party, then that individual or company has the right to ask the court to rule
that such patents are invalid or should not be enforced. Additionally, the validity of our patents and the patents we have licensed may be challenged if a petition for post grant
proceedings  such  as  inter-partes  review  and  post  grant  review  is  filed  within  the  statutorily  applicable  time  with  the  US  Patent  and  Trademark  Office  (“USPTO”).  These
lawsuits and proceedings are expensive and would consume time and resources and divert the attention of managerial and scientific personnel even if we were successful in
stopping the infringement of such patents. In addition, there is a risk that the court will decide that such patents are not valid and that we do not have the right to stop the other
party from using the inventions. There is also the risk that, even if the validity of such patents is upheld, the court will refuse to stop the other party on the ground that such
other party's activities do not infringe our intellectual property rights. In addition, in recent years the US Supreme Court modified some tests used by the USPTO in granting
patents over the past 20 years, which may decrease the likelihood that we will be able to obtain patents and increase the likelihood of a challenge of any patents we obtain or
license.

We may be subject to claims that our employees have wrongfully used or disclosed alleged trade secrets of their former employers.

As is common in the biotechnology and pharmaceutical industries, we employ individuals who were previously employed at other biotechnology or pharmaceutical
companies,  including  our  competitors  or  potential  competitors.  We  may  be  subject  to  claims  that  these  employees,  or  we,  have  used  or  disclosed  trade  secrets  or  other
proprietary information of their former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims,
litigation could result in substantial costs and be a distraction to management.

If  we  are  not  able  to  adequately  prevent  disclosure  of  trade  secrets  and  other  proprietary  information,  the  value  of  our  technology  and  products  could  be  significantly
diminished.

We  rely  on  trade  secrets  to  protect  our  proprietary  technologies,  especially  where  we  do  not  believe  patent  protection  is  appropriate  or  obtainable.  However,  trade
secrets are difficult to protect. We rely in part on confidentiality agreements with our employees, consultants, outside scientific collaborators, sponsored researchers and other
advisors to protect our trade secrets

30

 
 
 
 
 
 
and other proprietary information. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of
unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets and proprietary information. Costly and time-consuming
litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection could adversely affect our
competitive business position.

Risks Relating to Our Business and Our Financial Condition

We  will  require  substantial  additional  funding,  which  may  not  be  available  to  us  on  acceptable  terms,  or  at  all,  and,  if  not  so  available,  may  require  us  to  delay,  limit,
reduce or cease our operations.

We  have  used  and  we  intend  to  use  the  proceeds  from  any  possible  future  offerings,  to,  among  other  uses,  advance  Annamycin  and  WP1066  through  clinical
development, advancing the remainder of the existing portfolio through preclinical studies and into INDs or their equivalent, and sponsoring research at MD Anderson and HPI.
Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. We will require substantial additional future capital in order to
complete clinical development and commercialize Annamycin and WP1066. Based on the results of our Annamycin Phase 1 clinical trials, we intend to enter discussions with
the FDA and EMA about conducting a single arm Phase 2 study that would be the pivotal trial supporting US and European approval of Annamycin for relapsed or refractory
AML. We can provide no assurance that the FDA will permit such reliance and we may be required to conduct additional trials. If the FDA or its EU equivalent requires that we
perform  additional  nonclinical  studies  or  clinical  trials,  our  expenses  would  further  increase  beyond  what  we  currently  expect  and  the  anticipated  timing  of  any  potential
approval of Annamycin would likely be delayed. Further, there can be no assurance that the costs we will need to incur to obtain regulatory approval of Annamycin will not
increase.

Because successful development of our product candidates is uncertain, we are unable to estimate the actual amount of funding we will require to complete research and
development and commercialize our products under development.

The amount and timing of our future funding requirements will depend on many factors, including but not limited to:

•

whether our plan for clinical trials will be completed on a timely basis and, if completed, whether we will be able to publicly announce results from our phase

I/II clinical trials in accordance with our announced milestones;

•

whether  the  results  of  our  clinical  trials  will  be  announced  on  a  timely  basis  and,  when  announced,  whether  such  results  are  in  accordance  with  our

expectations or our announced milestones;

•

whether  the  FDA  and  EMA  will  allow  us  to  conduct  a  single  arm  Phase  2  study  that  would  be  the  pivotal  trial  supporting  US  and  European  approval  of

Annamycin for relapsed or refractory AML;

•
candidates;

•

•

•

•

•

•

whether  we  are  successful  in  obtaining  the  benefits  of  FDA’s  expedited  development  and  review  programs  related  to  Annamycin  or  our  other  drug

 the progress, costs, results of and timing of our clinical trials and also of our preclinical studies;

 the outcome, costs and timing of seeking and obtaining FDA and any other regulatory approvals;

the costs associated with securing and establishing commercialization and manufacturing capabilities;

market acceptance of our product candidates;

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

our ability to maintain, expand and enforce the scope of our intellectual property portfolio, including the amount and timing of any payments we may be

required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights;

•

•

our need and ability to hire additional management and scientific and medical personnel;

the effect of competing drug candidates and new product approvals;

31

 
 
 
 
 
  
 
 
 
 
 
 
 
•

•

our need to implement additional internal systems and infrastructure, including financial and reporting systems; and

the economic and other terms, timing of and success of our existing licensing arrangements and any collaboration, licensing or other arrangements into which

we may enter in the future.

Some  of  these  factors  are  outside  of  our  control.  Based  upon  our  currently  expected  level  of  operating  expenditures,  we  believe  that  we  will  be  able  to  fund  our
operational plan into the third quarter of 2020, assuming a significant amount of our outstanding warrants are not exercised for cash, and assuming we do not complete any
additional  equity  raises  or  draw  from  our  Lincoln  Park  facility  or  our ATM.  This  period  could  be  shortened  if  there  are  any  significant  increases  in  planned  spending  on
development  programs  or  more  rapid  progress  of  development  programs  than  anticipated.  Our  existing  capital  resources  are  not  sufficient  to  enable  us  to  complete  the
development and commercialization of Annamycin, WP1066, and WP1220, if approved, or to initiate any clinical trials or additional development work needed for any other
drug candidates. Accordingly, we will need to raise additional funds in the near future.

We may seek additional funding through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing
and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. Additional funding may not be available to us on acceptable terms or at
all.  In  addition,  the  terms  of  any  financing  may  adversely  affect  the  holdings  or  the  rights  of  our  stockholders.  In  addition,  the  issuance  of  additional  shares  by  us,  or  the
possibility of such issuance, may cause the market price of our shares to decline.

If we are unable to obtain funding on a timely basis, we may be required to significantly curtail one or more of our research or development programs. We also could
be  required  to  seek  funds  through  arrangements  with  collaborative  partners  or  otherwise  that  may  require  us  to  relinquish  rights  to  some  of  our  technologies  or  product
candidates or otherwise agree to terms unfavorable to us.

If  another  shutdown  of  the  federal  government  occurs,  we  will  not  be  able  to  effectively  utilize  a  Form  S-1  registration  statement  to  conduct  a  primary  offering  of  our
securities, which will limit this avenue to raise financing and may require us to raise financing on less favorable terms.

The  US  federal  government  shutdown  from  December  22,  2018  until  January  25,  2019  and  may  shutdown  again  in  the  near  future.  During  the  pendency  of  any
shutdown and assuming (as recently occurred) SEC operations during such shutdown prevent the SEC staff from declaring registration statements effective, we will be unable to
effectively utilize a Form S-1 registration statement for a primary offering of our securities. As such, any financing we conduct during a shutdown would be limited to offerings
from our currently effective Form S-3 registration statement or equity offered via the Lincoln Park facility or our ATM facility, which would be severely limited in size due to
statutory restrictions on our use of such registration statement, or from private placements, which generally carry less favorable terms due to the trading restrictions on such
securities. Our inability to raise financing or our inability to raise financing on favorable terms, could cause the trading price of our common stock to decline substantially.

We have commenced clinical trials, have  a  limited  operating  history  and  we  expect  a  number  of  factors  to  cause  our  operating  results  to  fluctuate  on  an  annual  basis,
which may make it difficult to predict our future performance.

We  are  a  clinical  stage  pharmaceutical  company  with  a  limited  operating  history.  Our  operations  to  date  have  been  limited  to  acquiring  our  technology  portfolio,
preparing several drugs for authorization to conduct clinical trials and commencing Phase 1 clinical trials. We have only recently commenced Phase 1 clinical trials and have yet
to receive regulatory approvals for any of our drug candidates. With regard to Annamycin, we believe the FDA has taken a more risk adverse view than European regulatory
authorities, placing greater restrictions on our ability to increase dosing for AML patients, which could cause development in the US to lag behind development in Europe.
Additionally, we have a limited amount of drug supply and the amount of drug required may depend upon patient response and the need for additional, unplanned treatments,
making it difficult to predict the total amount of drug required.

Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had a longer operating history or approved
products on the market. Our operating results are expected to significantly fluctuate from quarter-to-quarter or year-to-year due to a variety of factors, many of which are beyond
our control. Factors relating to our business that may contribute to these fluctuations include:

•

any delays in regulatory review and approval of our product candidates in clinical development, including our ability to receive approval from the FDA or the

Polish authorities for our drugs in clinical trials;

potential side effects of our product candidates that could delay or prevent approval or cause an approved drug to be taken off the market;

our ability to obtain additional funding to develop drug candidates;

our ability to identify and develop additional drug candidates beyond Annamycin and our WP1066 and WP1122 Portfolios;

competition from existing products or new products that continue to emerge;

the ability of patients or healthcare providers to obtain coverage or sufficient reimbursement for our products;

our ability to adhere to clinical trial requirements directly or with third parties such as contract research organizations (CROs);

our dependency on third-party manufacturers to manufacture our products and key ingredients;

our ability to establish or maintain collaborations, licensing or other arrangements, particularly with MD Anderson;

our ability to defend against any challenges to our intellectual property including, claims of patent infringement;

our ability to enforce our intellectual property rights against potential competitors;

our ability to secure additional intellectual property protection for our developing drug candidates and associated technologies;

our ability to attract and retain key personnel to manage our business effectively; and

potential product liability claims.

Accordingly, the results of any historical quarterly or annual periods should not be relied upon as indications of future operating performance.

We have in the past completed related party transactions that were not conducted on an arm’s length basis.

Prior to our IPO, we acquired (i) the rights to the license agreement with MD Anderson covering our WP1122 Portfolio held by IntertechBio Corporation, a company
affiliated with certain members of our management and board of directors, and (ii) the rights to all data related to the development of Annamycin held by AnnaMed, Inc., a
company  affiliated  with  certain  members  of  our  management  and  board  of  directors.  In  addition,  prior  to  our  IPO,  Moleculin,  LLC  merged  with  and  into  our  company.
Moleculin, LLC was affiliated with certain members of our management and board of directors. Prior to our IPO, we, on Moleculin, LLC’s behalf, entered into an agreement
with HPI whereby HPI agreed to terminate its option to sublicense certain rights to the WP1066 Portfolio and entered into a co-development agreement with us. Our largest
shareholder, Dr. Waldemar Priebe, and a member of our management are shareholders of HPI. In addition, in February 2019, we entered into sublicense agreements with WPD
Pharmaceuticals, Inc. and Animal Lifesciences, LLC. Dr. Priebe is affiliated with both WPD Pharmaceuticals, Inc. and Animal Lifesciences, LLC.

In  February  2019,  we  entered  into  sublicense  agreements  with  WPD  Pharmaceuticals,  Inc.  and Animal  Lifesciences,  LLC.  Dr.  Priebe  is  affiliated  with  both  WPD

Pharmaceuticals, Inc. and Animal Lifesciences, LLC.

For the sublicense agreements with WPD Pharmaceuticals, Inc., since Dr. Priebe was affiliated with the entity, our board of directors received a fairness opinion from
Roth Capital Partners, LLC as to the adequacy of the consideration we received in the sublicense agreement. We did not receive a fairness opinion on the transactions that
occurred prior to our IPO or with Animal Lifesciences, LLC. None of the foregoing transactions were conducted on an arm’s length basis. As such, it is possible that the terms
were less favorable to us than in an arm’s length transaction.

We have never been profitable, we have no products approved for commercial sale, and to date we have not generated any revenue from product sales. As a result, our
ability to reduce our losses and reach profitability is unproven, and we may never achieve or sustain profitability.

We have never been profitable and do not expect to be profitable in the foreseeable future. We have not yet submitted any drug candidates for approval by regulatory
authorities in the United States or elsewhere. For the year ended December 31, 2019, we incurred a net loss of $13.2 million. We had an accumulated deficit of $39.6 million as
of December 31, 2019.

To date, we have devoted most of our financial resources to research and development, including our drug discovery research, preclinical development activities and
clinical trial preparation, as well as corporate overhead. We have not generated any revenues from product sales. We expect to continue to incur losses for the foreseeable future,
and we expect these losses to increase as we continue our development of, and seek regulatory approvals for Annamycin and our other drug candidates, prepare for and begin
the commercialization of any approved products, and add infrastructure and personnel to support our continuing product development efforts. We anticipate that any such losses
could be significant for the next several years. If Annamycin, WP1066 or any of our other drug candidates fail in clinical trials or do not gain regulatory approval, or if our drug
candidates do not achieve market acceptance, we may never become profitable. As a result of the foregoing, we expect to continue to experience net losses and negative cash
flows for the foreseeable future. These net losses and negative cash flows have had, and will continue to have, an adverse effect on our stockholders' equity and working capital.

We conduct operations through our Australia wholly owned subsidiary. If we lose our ability to operate in Australia, or if our subsidiary is unable to receive the research
and development tax credit allowed by Australian regulations, our business and results of operations will suffer.

In June 2018, we formed a wholly owned Australian subsidiary, Moleculin Australia Pty Ltd, or (MAPL), to begin preclinical development in Australia for WP1732,
an analog of WP1066. Due to the geographical distance and lack of employees currently in Australia, as well as our lack of experience operating in Australia, we may not be
able to efficiently or successfully monitor, develop and commercialize our drug products in Australia, including conducting preclinical studies and clinical trials. Furthermore,
we have no assurance that the results of any clinical trials that we conduct for our drug candidates in Australia will be accepted by the FDA or foreign regulatory authorities for
development and commercialization approvals.

In  addition,  current Australian  tax  regulations  provide  for  a  refundable  research  and  development  tax  credit  equal  to  43.5%  of  qualified  expenditures.  If  we  are
ineligible or unable to receive the research and development tax credit, or if we lose our ability to operate MAPL in Australia, or the Australian government significantly reduces
or eliminates the tax credit, our business and results of operations would be adversely affected. We applied for a refundable tax credit and received in 2019 for $0.2 million

The sale or issuance of our common stock to Lincoln Park may cause dilution and the sale of the shares of common stock acquired by Lincoln Park, or the perception that
such sales may occur, could cause the price of our common stock to fall.

On October 4, 2018, we entered into the Purchase Agreement with Lincoln Park, pursuant to which Lincoln Park has committed to purchase up to $20,000,000 of our
common stock. Upon the execution of the Purchase Agreement, we issued 243,013 Commitment Shares to Lincoln Park as a fee for its commitment to purchase shares of our
common stock under the Purchase Agreement. The remaining shares of our common stock that may be issued under the Purchase Agreement may be sold by us to Lincoln Park
at our discretion from time to time over a 36-month period commencing after the satisfaction of certain conditions set forth in the Purchase Agreement. The purchase price for
the shares that we may sell to Lincoln Park under the Purchase Agreement will fluctuate based on the price of our common stock. Depending on market liquidity at the time,
sales of such shares may cause the trading price of our common stock to fall.

We  generally  have  the  right  to  control  the  timing  and  amount  of  any  future  sales  of  our  shares  to  Lincoln  Park. Additional  sales  of  our  common  stock,  if  any,  to
Lincoln Park will depend upon market conditions and other factors to be determined by us. We may ultimately decide to sell to Lincoln Park all, some or none of the additional
shares of our common stock that may be available for us to sell pursuant to the Purchase Agreement. If and when we do sell shares to Lincoln Park, after Lincoln Park has
acquired the shares, Lincoln Park may resell all, some or none of those shares at any time or from time to

34

 
 
time in its discretion. Therefore, sales to Lincoln Park by us could result in substantial dilution to the interests of other holders of our common stock. Additionally, the sale of a
substantial number of shares of our common stock to Lincoln Park, or the anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities
in the future at a time and at a price that we might otherwise wish to effect sales.

Our financial condition would be adversely impacted if our intangible assets become impaired.

As a result of the accounting for our acquisition of Moleculin, LLC and the agreement we, on Moleculin, LLC’s behalf, entered into with Houston Pharmaceuticals,
Inc., we have carried on our balance sheet within intangible assets in-process research and development (“IPR&D”) of $11.1 million as of December 31, 2019. Intangibles are
evaluated quarterly and are tested for impairment at least annually or when events or changes in circumstances indicate the carrying value of each segment, and collectively our
company taken as a whole, might exceed its fair value. 

Intangible  assets  related  to  IPR&D  are  considered  indefinite-lived  intangible  assets  and  are  assessed  for  impairment  annually  or  more  frequently  if  impairment
indicators  exist.  If  the  associated  research  and  development  effort  is  abandoned,  the  related  assets  will  be  written-off  and  we  will  record  a  noncash  impairment  loss  on  our
statement of operations. For those compounds that reach commercialization, if any, the IPR&D assets will be amortized over their estimated useful lives.

If we determine that the value of our intangible assets is  less  than  the  amounts  reflected  on  our  balance  sheet,  we  will  be  required  to  reflect  an  impairment  of  our
intangible assets in the period in which such determination is made. An impairment of our intangible assets would result in our recognizing an expense in the amount of the
impairment in the relevant period, which would also result in the reduction of our intangible assets and a corresponding reduction in our stockholders’ equity in the relevant
period. As the transactions discussed above were related party transactions and were not conducted on an arm’s length basis, it is possible that the terms were less favorable to
us than what we would have received in an arm’s length transaction.

We have no sales, marketing or distribution experience and we will have to invest significant resources to develop those capabilities or enter into acceptable third-party
sales and marketing arrangements.

We  have  no  sales,  marketing  or  distribution  experience.  To  develop  sales,  distribution  and  marketing  capabilities,  we  will  have  to  invest  significant  amounts  of
financial  and  management  resources,  some  of  which  will  need  to  be  committed  prior  to  any  confirmation  that Annamycin  or  any  of  our  other  product  candidates  will  be
approved by the FDA. For product candidates where we decide to perform sales, marketing and distribution functions ourselves or through third parties, we could face a number
of additional risks, including that we or our third-party sales collaborators may not be able to build and maintain an effective marketing or sales force. If we use third parties to
market and sell our products, we may have limited or no control over their sales, marketing and distribution activities on which our future revenues may depend.

We may not be successful in establishing and maintaining development and commercialization collaborations, which could adversely affect our ability to develop certain of
our product candidates and our financial condition and operating results.

Because developing pharmaceutical products, conducting clinical trials, obtaining regulatory approval, establishing manufacturing capabilities and marketing approved
products are expensive, we may seek to enter into collaborations with companies that have more experience. Additionally, if any of our product candidates receives marketing
approval, we may enter into sales and marketing arrangements with third parties. If we are unable to enter into arrangements on acceptable terms, if at all, we may be unable to
effectively market and sell our products in our target markets. We expect to face competition in seeking appropriate collaborators. Moreover, collaboration arrangements are
complex and time consuming to negotiate, document and implement and they may require substantial resources to maintain. We may not be successful in our efforts to establish
and implement collaborations or other alternative arrangements for the development of our product candidates.

When we collaborate with a third party for development and commercialization of a product candidate, we can expect to relinquish some or all of the control over the
future success of that product candidate to the third party. For example, we have formed a collaboration with a Polish drug development company called Dermin. In 2019, some
of these rights were transferred to WPD Pharmaceuticals, Inc. via an additional sublicense. The territories covered by these sublicense agreements are primarily Poland and
lesser surrounding countries, but not including any of the major European markets (UK, Germany, France, Spain and Italy).

One  or  more  of  our  collaboration  partners  may  not  devote  sufficient  resources  to  the  commercialization  of  our  product  candidates  or  may  otherwise  fail  in  their
commercialization. The terms of any collaboration or other arrangement that we establish may contain provisions that are not favorable to us. In addition, any collaboration that
we enter into may be

35

 
 
 
 
 
 
unsuccessful  in  the  development  and  commercialization  of  our  product  candidates.  In  some  cases,  we  may  be  responsible  for  continuing  preclinical  and  initial  clinical
development of a product candidate or research program under a collaboration arrangement, and the payment we receive from our collaboration partner may be insufficient to
cover the cost of this development. If we are unable to reach agreements with suitable collaborators for our product candidates, we would face increased costs, we may be forced
to limit the number of our product candidates we can commercially develop or the territories in which we commercialize them. As a result, we might fail to commercialize
products or programs for which a suitable collaborator cannot be found. If we fail to achieve successful collaborations, our operating results and financial condition could be
materially and adversely affected.

We face competition from other biotechnology and pharmaceutical companies and our operating results will suffer if we fail to compete effectively.

The  biotechnology  and  pharmaceutical  industries  are  intensely  competitive  and  subject  to  rapid  and  significant  technological  change.  We  have  competitors  in  the
United  States,  Europe  and  other  jurisdictions,  including  major  multinational  pharmaceutical  companies,  established  biotechnology  companies,  specialty  pharmaceutical  and
generic  drug  companies  and  universities  and  other  research  institutions.  Many  of  our  competitors  have  greater  financial  and  other  resources,  such  as  larger  research  and
development staff and more experienced marketing and manufacturing organizations than we do. Large pharmaceutical companies, in particular, have extensive experience in
clinical testing, obtaining regulatory approvals, recruiting patients and manufacturing pharmaceutical products. These companies also have significantly greater research, sales
and marketing capabilities and collaborative arrangements in our target markets with leading companies and research institutions. Established pharmaceutical companies may
also invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make the product candidates that we develop
obsolete. As a result of all of these factors, our competitors may succeed in obtaining patent protection and/or FDA approval or discovering, developing and commercializing
drugs for the diseases that we are targeting before we do or may develop drugs that are deemed to be more effective or gain greater market acceptance than ours. Smaller or
early-stage  companies  may  also  prove  to  be  significant  competitors,  particularly  through  collaborative  arrangements  with  large,  established  companies.  In  addition,  many
universities and private and public research institutes may become active in our target disease areas. Our competitors may succeed in developing, acquiring or licensing on an
exclusive  basis,  technologies  and  drug  products  that  are  more  effective  or  less  costly  than  any  of  our  product  candidates  that  we  are  currently  developing  or  that  we  may
develop, which could render our products obsolete or noncompetitive.

A number of attempts have been made or are under way to provide an improved treatment for AML. Drugs attempting to target a subset of AML patients who present
with particular anomalies involving a gene referred to as FLT3 are currently in clinical trials. Other approaches to improve the effectiveness of induction therapy are in early
stage clinical trials and, although they do not appear to address the underlying problems with anthracyclines, we can provide no assurance that such improvements, if achieved,
would not adversely impact the need for improved anthracyclines. A modified version of doxorubicin designed to reduce cardiotoxicity is in clinical trials for the treatment of
sarcoma and, although this drug does not appear to address multidrug resistance and is not currently intended for the treatment of acute leukemia, we can provide no assurance
that it will not become a competitive alternative to Annamycin. Although we are not aware of any other single agent therapies in clinical trials that would directly compete
against Annamycin  in  the  treatment  of  relapsed  and  refractory AML,  we  can  provide  no  assurance  that  such  therapies  are  not  in  development,  will  not  receive  regulatory
approval and will reach market before our drug candidate Annamycin. In addition, any such competing therapy may be more effective and / or cost-effective than ours.

If our competitors market products that are more effective, safer or less expensive or that reach the market sooner than our future products, if any, we may not achieve
commercial success. In addition, because of our limited resources, it may be difficult for us to stay abreast of the rapid changes in each technology. If we fail to stay at the
forefront of technological change, we may be unable to compete effectively. Technological advances or products developed by our competitors may render our technologies or
product candidates obsolete, less competitive or not economical.

We will need to expand our operations and increase the size of our company, and we may experience difficulties in managing growth.

As of December 31, 2019, we had eleven full-time and five part-time employees. As we advance our product candidates through preclinical studies and clinical trials,
we will need to increase our product development, scientific and administrative headcount to manage these programs. In addition, to meet our obligations as a public company,
we may need to increase our general and administrative capabilities. Our management, personnel and systems currently in place may not be adequate to support this future
growth. If we are unable to successfully manage this growth and increased complexity of operations, our business may be adversely affected.

36

 
 
 
 
We may not be able to manage our business effectively if we are unable to attract and retain key personnel and consultants.

We may not be able to attract or retain qualified management, finance, scientific and clinical personnel and consultants due to the intense competition for qualified
personnel and consultants among biotechnology, pharmaceutical and other businesses. If we are not able to attract and retain necessary personnel and consultants to accomplish
our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and
our ability to implement our business strategy.

We  are  highly  dependent  on  the  development,  regulatory,  commercialization  and  business  development  expertise  of  our  management  team,  key  employees  and
consultants. If we lose one or more of our executive officers or key employees or consultants, our ability to implement our business strategy successfully could be seriously
harmed.  Any  of  our  executive  officers  or  key  employees  or  consultants  may  terminate  their  employment  at  any  time.  Replacing  executive  officers,  key  employees  and
consultants may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience
required to develop, gain regulatory approval of and commercialize products successfully. Competition to hire and retain employees and consultants from this limited pool is
intense,  and  we  may  be  unable  to  hire,  train,  retain  or  motivate  these  additional  key  personnel  and  consultants.  Our  failure  to  retain  key  personnel  or  consultants  could
materially harm our business.

In addition, we have scientific and clinical advisors and consultants who assist us in formulating our research, development and clinical strategies. These advisors are
not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us and typically they will not enter
into non-compete agreements with us. If a conflict of interest arises between their work for us and their work for another entity, we may lose their services. In addition, our
advisors may have arrangements with other companies to assist those companies in developing products or technologies that may compete with ours.

We do not expect that our insurance policies will cover all of our business exposures thus leaving us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. There can be no assurance that we will secure adequate insurance coverage or that
any such insurance coverage will be sufficient to protect our operations to significant potential liability in the future. Any significant uninsured liability may require us to pay
substantial amounts, which would adversely affect our financial position and results of operations.

Additionally, we use hazardous materials, and any claims relating to improper handling, storage or disposal of these materials could be time-consuming or costly. We
do not carry specific hazardous waste insurance coverage and our property and casualty, and general liability insurance policies specifically exclude coverage for damages and
fines arising from hazardous waste exposure or contamination.

We may incur penalties if we fail to comply with healthcare regulations.

We are exposed to the risk of employee fraud or other illegal activity by our employees, independent contractors, consultants, commercial partners and vendors. In
addition to FDA restrictions on the marketing of pharmaceutical products, several other types of state and federal laws have been applied to restrict certain marketing practices
in the pharmaceutical and medical device industries in recent years, as well as consulting or other service agreements with physicians or other potential referral sources. These
laws include anti-kickback statutes and false claims statutes that prohibit, among other things, knowingly and willfully offering, paying, soliciting or receiving remuneration to
induce, or, in return for, purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or
other federally-financed healthcare programs, and knowingly presenting, or causing to be presented, a false claim for payment to the federal government, or knowingly making,
or causing to be made, a false statement to get a false claim paid. The majority of states also have statutes or regulations similar to the federal anti-kickback law and false claims
laws, which apply to items and services, reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payer. Although there are a number of
statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution, the exemptions and safe harbors are drawn narrowly, and any practices
we adopt may not, in all cases, meet all of the criteria for safe harbor protection from anti-kickback liability. Sanctions under these federal and state laws may include civil
monetary penalties, exclusion of a manufacturer’s products from reimbursement under government programs, criminal fines and imprisonment. Any challenge to our business
practices under these laws could have a material adverse effect on our business, financial condition and results of operations.

37

 
 
 
 
 
We may not be able to recover from any catastrophic event affecting our suppliers.

Our  suppliers  may  not  have  adequate  measures  in  place  to  minimize  and  recover  from  catastrophic  events  that  may  substantially  destroy  their  capability  to  meet
customer needs, and any measures they may in place may not be adequate to recover production processes quickly enough to support critical timelines or market demands.
These  catastrophic  events  may  include  weather  events  such  as  tornadoes,  earthquakes,  floods  or  fires.  In  addition,  these  catastrophic  events  may  render  some  or  all  of  the
products at the affected facilities unusable.

We may be materially adversely affected in the event of cyber-based attacks, network security breaches, service interruptions, or data corruption.

We rely on information technology to process and transmit sensitive electronic information and to manage or support a variety of business processes and activities. We
use technology systems to record, process, and summarize financial information and results of operations for internal reporting purposes and to comply with regulatory financial
reporting,  legal,  and  tax  requirements.  Our  information  technology  systems,  some  of  which  are  managed  by  third-parties,  may  be  susceptible  to  damage,  disruptions  or
shutdowns  due  to  computer  viruses,  attacks  by  computer  hackers,  failures  during  the  process  of  upgrading  or  replacing  software,  databases  or  components  thereof,  power
outages,  hardware  failures,  telecommunication  failures,  user  errors  or  catastrophic  events. Although  we  have  developed  systems  and  processes  that  are  designed  to  protect
proprietary or confidential information and prevent data loss and other security breaches, such measures cannot provide absolute security. If our systems are breached or suffer
severe damage, disruption or shutdown and we are unable to effectively resolve the issues in a timely manner, our business and operating results may significantly suffer and we
may be subject to litigation, government enforcement actions or potential liability. Security breaches could also cause us to incur significant remediation costs, result in product
development delays, disrupt key business operations, including development of our product candidates, and divert attention of management and key information technology
resources.

Our business and operations would suffer in the event of third-party computer system failures, cyber-attacks on third-party systems or deficiency in our cyber security.

We rely on information technology (“IT”) systems, including third-party “cloud based” service providers, to keep financial records, maintain laboratory data, clinical
data,  and  corporate  records,  to  communicate  with  staff  and  external  parties  and  to  operate  other  critical  functions.  This  includes  critical  systems  such  as  email,  other
communication tools, electronic document repositories and archives. If any of these third-party information technology providers are compromised due to computer viruses,
unauthorized access, malware, natural disasters, fire, terrorism, war and telecommunication failures, electrical failures, cyber-attacks or cyber-intrusions over the internet, then
sensitive emails or documents could be exposed or deleted. Similarly, we could incur business disruption if our access to the internet is compromised and we are unable to
connect with third-party IT providers. The risk of a security breach or disruption, particularly through cyber-attacks or cyber intrusion, including by computer hackers, foreign
governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased.
In addition, we rely on those third parties to safeguard important confidential personal data regarding our employees and patients enrolled in our clinical trials. If a disruption
event were to occur and cause interruptions in a third-party IT provider’s operation, it could result in a disruption of our drug development programs. For example, the loss of
clinical trial data from completed, ongoing or planned clinical trials 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 results in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or
proprietary information, we could incur liability and development of our product candidates could be delayed, or could fail.

The recent coronavirus pandemic may impact our business including, but not limited to, the progress of clinical trials and the the production of our drug, which the latter
could adversely affect our clinical trials if we are unable to obtain sufficient supply.

In December 2019, a novel strain of coronavirus was reported to have surfaced in Wuhan, China. As of February 2020, the virus has spread to Italy, which reportedly
has  the  highest  number  of  coronavirus  infections  outside Asia.  We  currently  source  the  production  of Annamycin  in  Italy. Additionally,  some  clinics  in  Poland  have  put
limitations  on  access  to  the  monitoring  our  clinical  trials,  which  for  now  has  not  limited  the  progress  of  our  trials,  but  this  could  change  at  any  time.  The  impact  of  the
coronavirus  has  been  so  widespread  and  increasing,  that  not  all  future  impacts  can  be  predicted. As  such,  the  outbreak  of  the  coronavirus  worldwide  could  have  a  material
adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  These  effects  could  include  travel  bans  or  restrictions,  limited  access  to  required  facilities,
disruptions  from  the  temporary  closure  of  third-party  supplier  and  manufacturer  facilities,  or  restrictions  on  the  export  or  shipment  of  products.  The  extent  to  which  the
coronavirus impacts our results will depend on future developments, which are highly uncertain and cannot

38

be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among
others.

Our failure to comply with data protection laws and regulations could lead to government enforcement actions and significant penalties against us, and adversely impact
our operating results.

We are subject to US data protection laws and regulations (i.e., laws and regulations that address privacy and data security) at both the federal and state levels. The
legislative and regulatory landscape for data protection continues to evolve, and in recent years there has been an increasing focus on privacy and data security issues. Numerous
federal and state laws, including state data breach notification laws, state health information privacy laws, and federal and state consumer protection laws, govern the collection,
use, and disclosure of health-related and other personal information. In addition, we may obtain health information from third parties (e.g., healthcare providers who prescribe
our products) that are subject to privacy and security requirements under Health Insurance Portability and Accountability Act of 1996, or HIPAA. Although we are not directly
subject  to  HIPAA-other  than  potentially  with  respect  to  providing  certain  employee  benefits-we  could  be  subject  to  criminal  penalties  if  we  knowingly  obtain  or  disclose
individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA. Finally, a data breach affecting
sensitive personal information, including health information, could result in significant legal and financial exposure and reputational damages that could potentially have an
adverse effect on our business.

EU  Member  States,  Switzerland  and  other  countries  have  also  adopted  data  protection  laws  and  regulations,  which  impose  significant  compliance  obligations.  For
example, the collection and use of personal health data in the EU is governed by the provisions of the EU Data Protection Directive, or the Directive. The Directive and the
national implementing legislation of the EU Member States impose strict obligations and restrictions on the ability to collect, analyze and transfer personal data, including health
data from clinical trials and adverse event reporting. In particular, these obligations and restrictions concern the consent of the individuals to whom the personal data relates, the
information provided to the individuals, notification of data processing obligations to the competent national data protection authorities and the security and confidentiality of
the  personal  data.  Data  protection  authorities  from  the  different  E.U.  Member  States  may  interpret  the  Directive  and  national  laws  differently  and  impose  additional
requirements, which add to the complexity of processing personal data in the EU.

Guidance on implementation and compliance practices are often updated or otherwise revised. For example, the EU Data Protection Directive prohibits the transfer of
personal  data  to  countries  outside  of  the  European  Economic Area,  or  EEA,  that  are  not  considered  by  the  European  Commission  to  provide  an  adequate  level  of  data
protection. These countries include the United States.

The judgment by the Court of Justice of the EU in the Schrems case (Case C-362/14 Maximillian Schrems v. Data Protection Commissioner) determined the US-EU
Safe Harbor Framework, which was relied upon by many US entities as a basis for transfer of personal data from the EU to the US, to be invalid. US entities therefore, had only
the possibility to rely on the alternate procedures for such data transfer provided in the EU Data Protection Directive.

On February 29, 2016, however, the European Commission announced an agreement with the U.S. Department of Commerce, or DOC, to replace the invalidated Safe
Harbor framework with a new EU-US “Privacy Shield”. On July 12, 2016, the European Commission adopted a decision on the adequacy of the protection provided by the
Privacy  Shield.  The  Privacy  Shield  is  intended  to  address  the  requirements  set  out  by  the  Court  of  Justice  of  the  EU  in  its  Schrems  judgment  by  imposing  more  stringent
obligations  on  companies,  providing  stronger  monitoring  and  enforcement  by  the  DOC  and  the  Federal  Trade  Commission,  and  making  commitments  on  the  part  of  public
authorities regarding access to information. US companies have been able to certify to the DOC their compliance with the privacy principles of the Privacy Shield since August
1, 2016 and rely on the Privacy Shield certification to transfer of personal data from the EU to the US.

On  September  16,  2016,  the  Irish  privacy  advocacy  group  Digital  Rights  Ireland  brought  an  action  for  annulment  of  the  European  Commission  decision  on  the
adequacy of the Privacy Shield before the Court of Justice of the E.U. (Case T-670/16). Case T-670/16 is still pending. If the Court of Justice of the EU invalidates the Privacy
Shield, it will no longer be possible to rely on the Privacy Shield certification to transfer personal data from the EU to entities in the US. Adherence to the Privacy Shield is not,
however, mandatory. US-based  companies  are  permitted  to  rely  either  on  their  adherence  to  the  EU-US  Privacy  Shield  or  on  the  other  authorized  means  and  procedures  to
transfer personal data provided by the EU Data Protection Directive.

In addition, the EU Data Protection Regulation, intended to replace the current EU Data Protection Directive entered into force on May 24, 2016 and will apply from
May 25, 2018. The EU Data Protection Regulation will introduce new data protection requirements in the E.U. and substantial fines for breaches of the data protection rules.
The EU Data Protection

39

Regulation will increase our responsibility and liability in relation to personal data that we process, and we may be required to put in place additional mechanisms to ensure
compliance with the new data protection rules.

Our failure to  comply  with  these  laws,  or  changes  in  the  way  in  which  these  laws  are  implemented,  could  lead  to  government  enforcement  actions  and  significant

penalties against us, and adversely impact our business.

We depend on our information technology and infrastructure.

We rely on the efficient and uninterrupted operation of information technology systems, including mobile technologies, to manage our operations, to process, transmit
and  store  electronic  and  financial  information,  and  to  comply  with  regulatory,  legal  and  tax  requirements.  We  also  depend  on  our  information  technology  infrastructure  for
communications among our personnel, contractors, consultants and vendors. System failures or outages could compromise our ability to perform these functions in a timely
manner, which could harm our ability to conduct business or delay our financial reporting. Such failures could materially adversely affect our operating results and financial
condition.

In  addition,  we  depend  on  third  parties  to  operate  and  support  our  information  technology  systems.  These  third  parties  vary  from  multi-disciplined  to  boutique
providers,  and  they  may  or  could  have  access  to  our  computer  networks,  mobile  networks,  and  our  confidential  information.  Many  of  these  third  parties  subcontract  or
outsource some of their responsibilities to other third parties. As a result, our information technology systems, including those functions that are performed by third parties who
are involved with or have access to those systems, are very large and complex. Failure by any of these third-party providers to adequately deliver the contracted services, or
maintain  confidentiality,  could  have  an  adverse  effect  on  our  business,  which  in  turn  may  materially  adversely  affect  our  operating  results  and  financial  condition.  All
information technology systems, despite implementation of security measures, may be vulnerable to disability, failures or unauthorized access. If our information technology
systems were to fail or be breached, such failure or breach could materially adversely affect our ability to perform critical business functions and sensitive and confidential data
could be compromised.

 Risks Relating to Our Common Stock

Our stock price has been and may continue to be volatile, which could result in substantial losses for investors.

Since our IPO in June 2016, our stock price has ranged from a high of $9.58 to a low of $0.32, and the market price of our common stock is likely to continue to be
highly  volatile  and  could  fluctuate  widely  in  response  to  various  factors,  many  of  which  are  beyond  our  control.  In  addition,  the  securities  markets  have  from  time  to  time
experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These market fluctuations may also significantly
affect the market price of our common stock.

Your ownership may be diluted if additional capital stock is issued to raise capital, to finance acquisitions or in connection with strategic transactions.

We intend to seek to raise additional funds, finance acquisitions or develop strategic relationships by issuing equity or convertible debt securities, which would reduce
the  percentage  ownership  of  our  existing  stockholders.  Our  board  of  directors  has  the  authority,  without  action  or  vote  of  the  stockholders,  to  issue  all  or  any  part  of  our
authorized but unissued shares of common or preferred stock. Our certificate of incorporation authorizes us to issue up to 100,000,000 shares of common stock and 5,000,000
shares  of  preferred  stock.  Future  issuances  of  common  or  preferred  stock  would  reduce  your  influence  over  matters  on  which  stockholders  vote  and  would  be  dilutive  to
earnings per share. In addition, any newly issued preferred stock could have rights, preferences and privileges senior to those of the common stock. Those rights, preferences
and privileges could include, among other things, the establishment of dividends that must be paid prior to declaring or paying dividends or other distributions to holders of our
common stock or providing for preferential liquidation rights. These rights, preferences and privileges could negatively affect the rights of holders of our common stock, and the
right to convert such preferred stock into shares of our common stock at a rate or price that would have a dilutive effect on the outstanding shares of our common stock.

Shares issuable upon the exercise of outstanding options or warrants may substantially increase the number of shares available for sale in the public market and depress
the price of our common stock.

As of December 31, 2019, we had a material number of outstanding options and warrants to purchase shares of common stock. As of December 31, 2019, we had
warrants and options outstanding to purchase an aggregate of 10,763,995 shares of common stock at an average exercise price of $1.97 per share. To the extent any of these
options or warrants are exercised and any additional options or warrants are granted and exercised, there will be further dilution to stockholders and investors. Until the options
and warrants expire, these holders will have an opportunity to profit from any increase in the market

40

 
 
 
price of our common stock without assuming the risks of ownership. Holders of options and warrants may convert or exercise these securities at a time when we could obtain
additional capital on terms more favorable than those provided by the options or warrants. The exercise of the options and warrants will dilute the voting interest of the owners
of presently outstanding shares by adding a substantial number of additional shares of our common stock.

The concentration of our common stock ownership by our current management will limit your ability to influence corporate matters.

As of December 31, 2019, our founders, directors and executive officers beneficially own and are able to vote in the aggregate 15.1% of our outstanding common
stock. As  such,  our  founders,  directors  and  executive  officers,  as  stockholders,  will  continue  to  have  the  ability  to  exert  significant  influence  over  all  corporate  activities,
including the election or removal of directors and the outcome of tender offers, mergers, proxy contests or other purchases of common stock that could give our stockholders
the  opportunity  to  realize  a  premium  over  the  then-prevailing  market  price  for  their  shares  of  common  stock.  This  concentrated  control  will  limit  your  ability  to  influence
corporate matters and, as a result, we may take actions that our stockholders do not view as beneficial. In addition, such concentrated control could discourage others from
initiating changes of control. In such cases, the perception of our prospects in the market may be adversely affected and the market price of our common stock may decline. As
of March 11, 2020, our founders, directors and executive officers beneficially own and are able to vote in the aggregate 13.0% of our outstanding common stock

Certain provisions in our organizational documents could enable our board of directors to prevent or delay a change of control.

Our organizational documents contain provisions that may have the effect of discouraging, delaying or preventing a change of control of, or unsolicited acquisition

proposals, that a stockholder might consider favorable. These include provisions:

•

•

•

•

prohibiting the stockholders from acting by written consent;

requiring advance notice of director nominations and of business to be brought before a meeting of stockholders;

requiring a majority vote of the outstanding shares of common stock to amend the bylaws; and

limiting the persons who may call special stockholders’ meetings.

Furthermore,  our  board  of  directors  has  the  authority  to  issue  shares  of  preferred  stock  in  one  or  more  series  and  to  fix  the  rights  and  preferences  of  these  shares
without stockholder approval. Any series of preferred stock is likely to be senior to our common stock with respect to dividends, liquidation rights and, possibly, voting rights.
The ability of our board of directors to issue preferred stock also could have the effect of discouraging unsolicited acquisition proposals, thus adversely affecting the market
price of our common stock.

In  addition,  Delaware  law  makes  it  difficult  for  stockholders  that  recently  have  acquired  a  large  interest  in  a  corporation  to  cause  the  merger  or  acquisition  of  the
corporation against the directors’ wishes. Under Section 203 of the Delaware General Corporation Law, a Delaware corporation may not engage in any merger or other business
combination with an interested stockholder for a period of three years following the date that the stockholder became an interested stockholder except in limited circumstances,
including by approval of the corporation’s board of directors.

As a biotechnology company, we are at increased risk of securities class action litigation.

Biotechnology  companies  have  experienced  greater  than  average  stock  price  volatility  in  recent  years,  and  our  common  stock  price  has  been  particularly  volatile
ranging from a high of $9.58 to a low of $0.32. These broad market fluctuations may adversely affect the trading price or liquidity of our common stock. In the past, when the
market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the issuer. If any of our stockholders were to
bring such a lawsuit against us, we could incur substantial costs defending the lawsuit and the attention of management would be diverted from the operation of our business.

41

 
 
 
 
 
 
 
 
 
 
We have no intention of declaring dividends in the foreseeable future.

The decision to pay cash dividends on our common stock rests with our board of directors and will depend on our earnings, unencumbered cash, capital requirements
and financial condition. We do not anticipate declaring any dividends in the foreseeable future, as we intend to use any excess cash to fund our operations. Investors in our
common stock should not expect to receive dividend income on their investment, and investors will be dependent on the appreciation of our common stock to earn a return on
their investment.

If we are unable to maintain compliance with the listing requirements of The Nasdaq Capital Market, our common stock may be delisted from The Nasdaq Capital Market
which could have a material adverse effect on our financial condition and could make it more difficult for you to sell your shares.

Our common stock is listed on The Nasdaq Capital Market, and we are therefore subject to its continued listing requirements, including requirements with respect to
the  market  value  of  publicly-held  shares,  market  value  of  listed  shares,  minimum  bid  price  per  share,  and  minimum  stockholder's  equity,  among  others,  and  requirements
relating to board and committee independence. If we fail to satisfy one or more of the requirements, we may be delisted from The Nasdaq Capital Market.

Since February 6, 2020, we have been trading below the $1.00 minimum closing bid price requirement set forth in NASDAQ Listing Rule 5550(a)(2). On March 18,
we traded below that minimum for a total of 30 consecutive days, so we are out of compliance with NASDAQ, and will receive notice of noncompliance from NASDAQ. To
regain compliance, we must trade at or above $1.00 per share or greater for the 10 consecutive business days during the six months following receipt of such notice.

In the future, we may again fail to comply with the continued listing requirements of the Nasdaq Capital Market, which would subject our common stock to being
delisted. Delisting from The Nasdaq Capital Market would adversely affect our ability to raise additional financing through the public or private sale of equity securities, may
significantly affect the ability of investors to trade our securities and may negatively affect the value and liquidity of our common stock. Delisting also could have other negative
results, including the potential loss of employee confidence, the loss of institutional investors or interest in business development opportunities.

Failure to maintain effective internal control over our financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act could cause our financial reports to be
inaccurate.

We are required pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, to maintain internal control over financial reporting and to assess and
report on the effectiveness of those controls. This assessment includes disclosure of any material weaknesses identified by our management in our internal control over financial
reporting. Our management concluded that our internal controls over financial reporting were, and continue to be ineffective, and as of the year ended December 31, 2019,
identified a material weakness in our internal controls due to the lack of segregation of duties. While management is working to remediate the material weakness, there is no
assurance that such changes, when economically feasible and sustainable, will remediate the identified material weaknesses or that the controls will prevent or detect future
material weaknesses. If we are not able to maintain effective internal control over financial reporting, our financial statements, including related disclosures, may be inaccurate,
which could have a material adverse effect on our business.

Failure to continue improving our accounting systems and controls could impair our ability to comply with the financial reporting and internal controls requirements for
publicly traded companies.

As a public company, we operate in an increasingly demanding regulatory environment, which requires us to comply with the Sarbanes-Oxley Act of 2002, and the
related rules and regulations of the SEC. Company responsibilities required by the Sarbanes-Oxley Act include establishing corporate oversight and adequate internal control
over financial reporting and disclosure controls and procedures. Effective internal controls are necessary for us to produce reliable financial reports and are important to help
prevent financial fraud.

Management performed an annual assessment as of December 31, 2019 of the effectiveness of our internal control over financial reporting for its annual report. Our
management concluded that our internal control over financial reporting was, and continues to be, ineffective and as of the year ended December 31, 2019, due to a material
weakness in our internal controls due to the lack of segregation of duties. For as long as we remain an “emerging growth company” as defined in the JOBS Act, we have and
intend to consider to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth
companies” including, but not limited to, not being required to comply

42

 
 
 
 
 
 
 
 
 
with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act. We may continue to take advantage of these reporting exemptions until we are no longer
an “emerging growth company.” To remediate this material weakness, we engaged an outside firm to assist management with such accounting and will continue to use outside
firms  as  a  resource  to  deal  with  other  non-recurring  or  unusual  transactions.  However,  notwithstanding  our  remediation  efforts,  there  is  no  assurance  we  will  not  encounter
accounting errors in the future. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed, and investors could lose
confidence in our reported financial information.

As  an  “emerging  growth  company”  under  the  Jumpstart  Our  Business  Startups  Act,  or  JOBS  Act,  we  are  permitted  to,  and  intend  to,  rely  on  exemptions  from  certain
disclosure requirements.

As  an  “emerging  growth  company”  under  the  JOBS Act,  we  are  permitted  to,  and  intend  to,  rely  on  exemptions  from  certain  disclosure  requirements.  We  are  an

emerging growth company until the earliest of:

•

•

•

•

the last day of the fiscal year during which we have total annual gross revenues of $1 billion or more;

the last day of the fiscal year following the fifth anniversary of our IPO, or December 31, 2021;

the date on which we have, during the previous 3-year period, issued more than $1 billion in non-convertible debt; or

the date on which we are deemed a “large accelerated issuer” as defined under the federal securities laws.

For so long as we remain an emerging growth company, we will not be required to:

•

•

have an auditor report on our internal control over financial reporting pursuant to the Sarbanes-Oxley Act of 2002;

comply  with  any  requirement  that  may  be  adopted  by  the  Public  Company  Accounting  Oversight  Board  regarding  mandatory  audit  firm  rotation  or  a

supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis);

•

submit certain executive compensation matters to shareholders advisory votes pursuant to the “say on frequency” and “say on pay” provisions (requiring a
non-binding shareholder vote to approve compensation of certain executive officers) and the “say on golden parachute” provisions (requiring a non-binding shareholder vote to
approve  golden  parachute  arrangements  for  certain  executive  officers  in  connection  with  mergers  and  certain  other  business  combinations)  of  the  Dodd-Frank  Wall  Street
Reform and Consumer Protection Act of 2010;

•

include  detailed  compensation  discussion  and  analysis  in  our  filings  under  the  Securities  Exchange Act  of  1934,  as  amended,  and  instead  may  provide  a

reduced level of disclosure concerning executive compensation; and

•

may present only two years of audited financial statements and only two years of related Management’s Discussion and Analysis of Financial Condition and

Results of Operations, or MD&A.

We intend to take advantage of all of these reduced reporting requirements and  exemptions.  Certain  of  these  reduced  reporting  requirements  and  exemptions  were
already available to us due to the fact that we also qualify as a “smaller reporting company” under SEC rules. For instance, smaller reporting companies are not required to
obtain an auditor attestation and report regarding management’s assessment of internal control over financial reporting; are not required to provide a compensation discussion
and analysis; are not required to provide a pay-for-performance graph or CEO pay ratio disclosure; and may present only two years of audited financial statements and related
MD&A disclosure.

Under the JOBS Act, we may take advantage of the above-described reduced reporting requirements and exemptions until December 31, 2021, or such earlier time that
we no longer meet the definition of an emerging growth company. In this regard, the JOBS Act provides that we would cease to be an “emerging growth company” if we have
more than $1.0 billion in annual revenues, have more than $700 million in market value of our common stock held by non-affiliates, or issue more than $1.0 billion in principal
amount of non-convertible debt over a three-year period. Further, under current SEC rules, we will continue to qualify as a “smaller reporting company” for so long as we have a
public float (i.e., the market value of common equity held by non-affiliates) of less than $75 million as of the last business day of our most recently completed second fiscal
quarter.

43

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We cannot predict if investors will find our securities less attractive due to our reliance on these exemptions. If investors were to find our common stock less attractive

as a result of our election, we may have difficulty raising capital.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Our corporate executive offices, laboratory and other spaces are in located in leased facilities in Houston, Texas. In March 2018, we entered into a Lease Agreement
(the “Lease”) which we use for corporate office space and headquarters. The term of the Lease began in August 2018 and will continue for an initial term of 66 months, which
may be renewed for an additional 5 years. We are required to remit base monthly rent which will increase at an average approximate rate of 3% each year. We are also required
to pay additional rent in the form of our pro-rata share of certain specified operating expenses of the Landlord.

In August 2019, we entered into an Amended Lease Agreement (the "Lab Lease") which our lab space. The term of the Lab Lease began in September 2019 and will
continue for an initial term of 35 months, with no further right or option to renew. We are required to remit base monthly rent which will increase at an average approximate
rate  of  3%  each  year.  The  Lab  Lease  is  classified  as  an  operating  lease.  In August  2019,  we  entered  into  a  sublease  with  Houston  Pharmaceuticals,  Inc.  ("HPI"),  which  is
affiliated with Dr. Priebe. We granted HPI access to all of the Lab Lease space and HPI has agreed to pay us 50% of the rent payable under the Lab Lease less 50% of any
benefits from any sublease or other lab service agreement we may receive from its Lab Lease. Although HPI has access to the space, it is the intent of the parties that they
equally share the Lab Lease space for research purposes. We believe our facilities, as expanded, will be sufficient to meet our current needs and that suitable space will be
available as and when needed. We do not own any real property.

ITEM 3. LEGAL PROCEEDINGS

From time to time in the ordinary course of our business, we may be involved in legal proceedings, the outcomes of which may not be determinable. The results of
litigation are inherently unpredictable. Any claims against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of
management time and result in diversion of significant resources. We are not able to estimate an aggregate amount or range of reasonably possible losses for those legal matters
for  which  losses  are  not  probable  and  estimable,  primarily  for  the  following  reasons:  (i)  many  of  the  relevant  legal  proceedings  are  in  preliminary  stages,  and  until  such
proceedings develop further, there is often uncertainty regarding the relevant facts and circumstances at issue and potential liability; and (ii) many of these proceedings involve
matters of which the outcomes are inherently difficult to predict. We have insurance policies covering potential losses where such coverage is cost effective.

We are not at this time involved in any legal proceedings.

Market Information

Our  common  stock  is  listed  on  the  NASDAQ  Capital  Market  under  the  symbol  “MBRX”.  On  March  4,  2020,  the  closing  price  reported  on  the  NASDAQ  Capital

Market for our common stock was $0.70.

Holders

As of March 4, 2020, there were approximately 149 holders of record of our common stock. In addition, we believe that a significant number of beneficial owners of

our common stock hold their shares in nominee or in “street name” accounts through brokers.

Dividends

We have never paid any dividends on our common stock. The payment of dividends in the future will be contingent upon our revenues and earnings, if any, capital
requirements  and  general  financial  condition.  It  is  the  present  intention  of  our  Board  of  Directors  to  retain  all  earnings,  if  any,  for  use  in  our  business  operations  and,
accordingly, our Board of Directors does not anticipate declaring any dividends in the foreseeable future.

Recent Sales of Unregistered Securities

All information related to equity securities sold by us during the period covered by this report that were not registered under the Securities Act have been included in

our Form 10-Q filings or in a Form 8-K filing. We did not issue any equity securities during the fourth quarter of 2019 that were not registered under the Securities Act.

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

The following discussion should be read in conjunction with the Financial Statements and Notes thereto included in this Form 10-K. The forward-looking statements
included in this discussion and elsewhere in this Form 10-K involve risks and uncertainties, including those set forth under “Cautionary Statement About Forward-Looking

a number of factors, including but not limited to those discussed in this Item and in Item 1A - “Risk Factors.”

Overview

Our Business

Moleculin Biotech, Inc., a Delaware corporation, is a clinical stage pharmaceutical company focused on the treatment of highly resistant cancers. We have three core
technologies, all of which are based on discoveries made at MD Anderson Cancer Center ("MD Anderson"). We have three drug candidates that are active in clinical trials. In
2019, those three drug candidates were active in four clinical trials in the US and Poland with a fifth that is expected to begin in the first half of 2020. Of these five clinical trials,
two are primarily externally funded. For two of these trials, we successfully concluded the Phase 1

46

 
 
 
 
 
 
 
 
 
 
portion recently and are preparing to potentially move into Phase 2 trials. We anticipate laying the groundwork in 2020 for two additional Phase 1 trials expected to begin in
2021 sponsored by us and two other Phase 1 trials we expect to be externally sponsored.

Based on our positive clinical activity thus far, we have narrowed our development focus to our nearest term opportunities. We believe this will allow us to reduce our
cash needs until we reach a significant value inflection point, although we will continue to require additional external capital during this period. In addition, institutional support
for our technologies has increased and we believe such support may provide outside funding to help reduce future dilution.

Of  our  three  clinical  stage  drug  candidates, Annamycin  is  being  studied  for  the  treatment  of  relapsed  or  refractory  acute  myeloid  leukemia  (“AML”)  and  cancers
metastasized  to  the  lungs.  WP1066,  an  Immune/Transcription  Modulator  ("p-STAT3  inhibitor")  is  intended  to  target  a  wide  range  of  tumors,  including  brain  tumors  and
pancreatic cancer. We began and completed a Phase 1 clinical trial in 2019 in Poland for a third drug, WP1220 (a molecule similar to WP1066), for the topical treatment of
cutaneous T-cell lymphoma ("CTCL") and we are looking to expand development of this drug into a Moleculin Phase 2 trial. We are also engaged in preclinical development of
additional drug candidates, including additional Immune/Transcription Modulators, as well as Metabolism/Glycosylation Inhibitors.

We  consider  Annamycin  to  be  a  "next  generation"  anthracycline,  unlike  any  currently  approved  anthracyclines,  as  it  is  designed  to  avoid  multidrug  resistance
mechanisms with little to no cardiotoxicity (two problems common to all currently approved anthracyclines). We recently received an independent expert cardiology assessment
confirming the absence of cardiotoxicity in the first 14 patients treated with Annamycin in both our US and European Phase 1 clinical trials, validating Annamycin's lack of
cardiotoxicity. Annamycin is currently in one Phase 1/2 clinical trial in Europe with the Phase 1 portion of another Phase 1/2 AML trial recently concluding in the US. Upon
receipt of further data from the European Phase 1 trial, we plan to seek agreement with the FDA for accelerated approval of Annamycin based on a pivotal Phase 2 AML trial
sponsored by us, although there is no assurance that the FDA will agree with our proposal.

In  2019,  preclinical  work  on  Annamycin  demonstrated  activity  against  some  cancers  metastasized  to  the  lungs.  With  this  new  data,  we  are  planning  to  start  a

Moleculin-sponsored US Phase 1 trial at MD Anderson for the treatment of cancer metastasized to the lungs with Annamycin.

WP1066 is one of several Immune/Transcription Modulators designed to stimulate the immune response to tumors by inhibiting the errant activity of Regulatory T-
Cells (TRegs) while also inhibiting key oncogenic transcription factors, including p-STAT3, c-Myc and HIF-1α. These transcription factors are widely sought targets that may
also play a role in the inability of immune checkpoint inhibitors to affect more resistant tumors. WP1066 is currently in a US physician-sponsored Phase 1 trial for the treatment
of glioblastoma ("GBM") and another institutionally sponsored Phase 1 trial should begin soon for the treatment of pediatric brain tumors. Another physician-sponsored Phase 1
trial is being considered for the treatment of GBM with WP1066 in combination with radiation.

We are also developing new compounds designed to exploit the potential uses of inhibitors of glycolysis such as 2-deoxy-D-glucose (“2-DG”), which we believe may
provide an opportunity to cut off the fuel supply of tumors by taking advantage of their high level of dependence on glucose in comparison to healthy cells. A key drawback to
2-DG  is  its  lack  of  drug-like  properties,  including  a  short  circulation  time  and  poor  tissue/organ  distribution  characteristics.  Our  lead  Metabolism/Glycosylation  Inhibitor,
WP1122, is a prodrug of 2-DG that appears to improve the drug-like properties of 2-DG by increasing its circulation time and improving tissue/organ distribution. New research
also  points  to  the  potential  for  2-DG  to  be  capable  of  enhancing  the  usefulness  of  checkpoint  inhibitors.  Considering  that  2-DG  lacks  sufficient  drug-like  properties  to  be
practical in a clinical setting, we believe WP1122 has the opportunity to become an important drug to potentiate existing therapies, including checkpoint inhibitors. In March
2020,  we  entered  into  an  agreement  with  an  outside  research  center  who  will  conduct  research  on  WP1122  for  antiviral  properties  against  a  range  of  viruses,  including
Coronavirus.

Recent Developments

Offering

On  February  6,  2020,  we  entered  into  subscription  agreements  with  certain  institutional  investors  for  the  sale  of  up  to  7,500,000  shares  of  our  common  stock  and
warrants to purchase 5,625,000 shares of common stock at a combined public offering price of $0.80 per share and related warrant. The warrants will be exercisable six months
from the date of issuance at a price of $1.05 per share and will expire five years from the date they are first exercisable. The offering closed on February 10, 2020 and gross
proceeds of the offering were approximately $6.0 million, prior to deducting the placement agent fees and other estimated offering expenses.

Entry into a Material Definitive Agreement

On  March  16,  2020,  we  entered  into  a  material  transfer  agreement  with  The  University  of  Texas  Medical  Branch  at  Galveston,  d/b/a  UTMB  Health  ("UTMB"),  a
health institution of The University of Texas System ("System"), an agency of the State of Texas (the "Agreement"). Pursuant to the Agreement, we agreed to provide research
material(s) to UTMB. The materials will be used by UTMB to conduct research, specifically to test the effects of 2 deoxyglucose (2DG) and analogues thereof on the infectivity
of viruses, including Coronoavirus. The materials to be provided pursuant to the Agreement are subject to patent and technology license agreements we have with MD Anderson
Cancer Center.

Research and development (“R&D”) expense was $11.0 million and $9.7 million for the years ended December 31, 2019 and 2018, respectively. The increase in R&D
of approximately $1.3 million mainly relates to: increased clinical trial activity (2 drugs in 3 clinical trials in 2018, versus 3 drugs in 4 clinical trials in 2019) including the
manufacturing of additional drug product and the issuance of common stock for $0.5 million, related to the exercise of the option to reacquire certain license rights in Germany
under the Dermin License Agreements. These increases were offset by a reduction in various other R&D expenses.

General and Administrative Expense.

General and administrative (“G&A”) expense was $6.3 million and $5.2 million for the years ended December 31, 2019 and 2018, respectively. The increase in G&A
of approximately $1.1 million was mainly attributable to increase in payroll costs for additional finance and office staff, stock-based compensation expense for vested warrants
issued to a consultant, and annual employee stock options.

Gain from Change in Fair Value of Warrant Liability.

We recorded a gain of $4.1 million during the year ended December 31, 2019 as compared to a gain of approximately $3.2 million, during the year ended December
31, 2018, for the change in fair value on revaluation of our warrant liability associated with our warrants issued in conjunction with our stock offerings. We are required to
revalue certain of the warrants at the time of each warrant exercise and at the end of each reporting period and reflect in the statement of operations a gain or loss from the
change in fair value of the warrant in the period in which the change occurred. We calculated the fair value of the warrants outstanding using the Black-Scholes model. A gain
results principally from a decline in our share price during the period and a loss results principally from an increase in our share price.

Net Loss.

The net loss for the year ended December 31, 2019 was $13.2 million, which included non-cash gains of $4.1 million on warrants in 2019 as compared to $3.2 million

in the prior year and approximately $1.5 million of stock-based compensation expense in 2019 as compared to $1.1 million in 2018.

Liquidity and Capital Resources

As of December 31, 2019, we had cash and cash equivalents of $10.7 million and prepaid expenses and other of $2.7 million. We also had $2.2 million of accounts
payable and $1.4 million of accrued expenses. A significant portion of the accounts payable and accrued expenses are due to work performed in relation to our clinical trials. For
the  years  ended  December  31,  2019  and  2018,  we  used  approximately  $17.2  million  and  $12.2  million  of  cash  in  operating  activities,  respectively,  which  represents  cash
outlays for research and development and general and administrative expenses in such periods. The increase in 2019 reflects the increase in clinical and preclinical activity over
2018. For the year ended December 31, 2019, net proceeds from financing activities were $20.9 million, predominately from the sale of our common stock and warrants. In
2018, approximately $12.0 million was raised predominately through the sale of shares of common stock and the exercise of warrants. Cash used in investing activities for the
year ended December 31, 2019 was approximately $0.05 million primarily for the purchases of employee computer equipment and office furniture.

We  believe  that  our  cash  resources  as  of  December  31,  2019,  along  with  the  additional  funding  received  subsequent  to  year-end,  will  be  sufficient  to  meet  our
projected operating requirements towards the end of the third quarter of 2020. This expectation does not consider unplanned preclinical and clinical activity, additional funding,
including but not limited to, equity issuances including the use of the Lincoln Park or ATM facilities.

We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than currently expected due
to changes we may make in our research and development spending plans. These factors raise substantial doubt about our ability to continue as a going concern for the one-year
period from the date of filing of this Form 10-K. We believe we have the ability to obtain additional funding through public or private financing or collaborative arrangements
with strategic partners to increase the funds available to fund operations. Without additional funds, we may be forced to delay, scale back or eliminate some of our research and
development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events
occurs, our ability to achieve our development and commercialization goals would be adversely affected.

On October 4, 2018, we entered into a purchase agreement ("LP Purchase Agreement") with Lincoln Park Capital Fund, LLC ("Lincoln Park") and a registration rights
agreement pursuant to which Lincoln Park has agreed to purchase from us up to an aggregate of $20.0 million worth of our common stock. Under the terms and subject to the
conditions of the LP Purchase Agreement, we have the right, but not the obligation, to sell to Lincoln Park, and Lincoln Park is obligated to purchase up to $20.0 million worth
of shares of common stock. Such sales of common stock by us, if any, will be subject to certain limitations, and may occur from time to time, at our sole discretion, over the 36-
month period commencing on October 30, 2018. As of December 31, 2019 we have utilized $2.8 million under the LP Purchase Agreement.

In July 2019, we entered into an at-the-market equity agreement (the “ATM Agreement”) with Oppenheimer & Co. Inc. (the “Agent”). Pursuant to the  terms  of  the
ATM Agreement, we may sell from time to time through the Agent shares of our common stock, with an aggregate sales price of up to $15 million, subject to certain terms and
conditions. The offering of the shares pursuant to the ATM Agreement will terminate upon the sale of shares in an aggregate offering amount equal to $15 million, or sooner if
either we or the Agent terminate the ATM Agreement pursuant to its terms. We will pay a commission to the Agent of 3.0% of the gross proceeds of the sale of the shares sold
under the ATM Agreement and reimburse the Agent for certain expenses. We provided the Agent with customary indemnification rights. We have not sold any shares under the
ATM Agreement.

As  mentioned  above,  subsequent  to  year-end  in  February  2020  we  entered  into  subscription  agreements  with  certain  institutional  investors  for  the  sale  of  up  to
7,500,000 shares of our common stock and warrants to purchase 5,625,000 shares of common stock at a combined public offering price of $0.80 per share and related warrant.
The  warrants  will  be  exercisable  six  months  from  the  date  of  issuance  at  a  price  of  $1.05  per  share  and  will  expire  five  years  from  the  date  they  are  first  exercisable.  The
offering  closed  on  February  10,  2020  and  gross  proceeds  of  the  offering  were  approximately  $6.0  million,  prior  to  deducting  the  placement  agent  fees  and  other  estimated
offering expenses.

Net cash used in operating activities was $17.2 million for the year ended December 31, 2019 compared to $12.2 million for the year ended December 31, 2018. This
increase in use of cash for operations was mainly due to: 1) payments for developing, manufacturing and testing drug product as we prepared for clinical trials, including the
$1.0 million payment to HPI; 2) an increase in R&D employee and contractor headcount and associated payroll costs; 3) an increase in paid sponsored research and related
expenses; and 4) an increase in license fees. These are all a reflection of the ongoing clinical and pre-clinical activity and the associated increase in G&A support for our three
core drug technologies.

Cash used in investing activities

Net cash used in investing activities was $0.05 million for the year ended December 31, 2019 compared to $0.4 million for the year ended December 31, 2018. The
decrease relates to purchases in 2018 related to furniture and fixtures and leasehold improvements on the new office location, as well as the installation of a new accounting
system in 2018.

Cash provided by financing activities

Net cash provided by financing activities was $20.9 million for the year ended December 31, 2019 compared to the prior period of $12.0 million. Net cash provided by
financing in 2019 consisted primarily of $19.3 million net proceeds from issuance of common stock, and $1.6 million net proceeds from the exercise of warrants. The prior
period financing activities consisted primarily of net proceeds from issuance of common stock.

Off-Balance Sheet Transactions

We do not engage in off-balance sheet transactions.

JOBS Act and Recent Accounting Pronouncements

The JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act
of 1933, as amended, for complying with new or revised accounting standards. In other words, an “emerging growth company” can 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 extended transition period and, as a result,
we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other public companies. 

We have implemented all new accounting pronouncements that are in effect and may impact our financial statements and we do not believe that there are any other

new accounting pronouncements that have been issued that might have a material impact on our financial position or results of operations.

Critical Accounting Policies and Significant Judgments and Estimates

Basis of Presentation

The accompanying consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United
States of America (“US GAAP”) for financial information, and in accordance with the rules and regulations of the United States Securities and Exchange Commission (the
“SEC”).

51

 
 
 
 
 
 
We believe that the following accounting policies are the most critical to aid in fully understanding and evaluating our reported financial results, and they require our

most difficult, subjective or complex judgments, resulting from the need to make estimates about the effect of matters that are inherently uncertain.

Research and Development Costs

We record accrued expenses for estimated costs of our research and development activities conducted by third-party service providers, which include the conduct of
pre-clinical and clinical studies and preparation for clinical trials and contract manufacturing activities. We record the estimated costs of research and development activities
based  upon  the  estimated  amount  of  services  provided  but  not  yet  invoiced,  and  we  include  these  costs  in  accrued  liabilities  in  the  balance  sheets  and  within  research  and
development expense in the statement of operations. These costs are a significant component of our research and development expenses. We record accrued expenses for these
costs based on the estimated amount of work completed and in accordance with agreements established with these third parties.

We estimate the amount of work completed through discussions with internal personnel and external service providers as to the progress or stage of completion of the
services and the agreed-upon fee to be paid for such services. We make significant judgments and estimates in determining the accrued balance in each reporting period. As
actual  costs  become  known,  we  adjust  our  accrued  estimates.  Although  we  do  not  expect  our  estimates  to  be  materially  different  from  amounts  actually  incurred,  our
understanding of the status and timing of services performed may vary from our estimates and could result in us reporting amounts that are too high or too low in any particular
period.  Our  accrued  expenses  are  dependent,  in  part,  upon  the  receipt  of  timely  and  accurate  reporting  from  clinical  research  organizations  and  other  third-party  service
providers. To date, there have been no material differences from our accrued expenses to actual expenses.

Impairment of Long-Lived Assets

Management  evaluates  the  recoverability  of  its  property  and  equipment  and  amortizable  intangible  assets  for  possible  impairment  whenever  events  or  changes  in
circumstances indicate that the carrying amount of such assets may not be recoverable or at a minimum annually during the fourth quarter of the year. Recoverability of these
assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying
amount of property and equipment and amortizable intangible assets is not recoverable, the carrying amount of such asset is reduced to fair value.

Acquired in-process research and development ("IPR&D") assets are considered indefinite lived until the completion or abandonment of the associated research and
development efforts. Management evaluates the recoverability of its IPR&D assets for possible impairment annually during the fourth quarter or whenever events or changes in
circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of IPR&D assets is measured by a comparison of the carrying amounts
its fair value. If such review indicates that the carrying amount of IPR&D assets is not recoverable, the carrying amount of such asset is reduced to fair value.

Components of our Results of Operations and Financial Condition

Operating expenses

We classify our operating expenses into three categories: research and development, general and administrative and depreciation.

Research and development. Research and development expenses consist primarily of:

•

•

•

costs incurred to conduct research, such as the discovery and development of our product candidates;

costs related to production of clinical supplies, including fees paid to contract manufacturers and drug manufacturing costs;

fees paid to clinical consultants, clinical trial sites and vendors, including clinical research organizations, in preparation for clinical trials and our IND and

Orphan Drug applications with the FDA; and

•

costs related to compliance with drug development regulatory requirements.

52

 
 
 
 
 
 
 
 
 
 
 
We recognize all research and development costs as they are incurred. Pre-clinical costs, contract manufacturing and other development costs incurred by third parties

are expensed as the contracted work is performed.

We expect our research and development expenses to increase in the future as we advance our product candidates into and through clinical trials and pursue regulatory
approval of our product candidates in the United States and Europe. The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-
consuming. The actual probability of success for our product candidates may be affected by a variety of factors including: the quality of our product candidates, early clinical
data, investment in our clinical program, competition, manufacturing capability and commercial viability. We may never succeed in achieving regulatory approval for any of
our product candidates. As a result of the uncertainties discussed above, we are unable to determine the duration and completion costs of our research and development projects
or when and to what extent, if any, we will generate revenue from the commercialization and sale of our product candidates.

General and administrative

General and administrative expense consists of personnel related costs, which include salaries, as well as the costs of professional services, such as accounting and
legal, facilities, information technology and other administrative expenses. We expect our general and administrative expense to increase due to the anticipated growth of our
business and related infrastructure as well as accounting, insurance, investor relations and other costs associated with becoming a public company.

Depreciation. Depreciation expense consists of depreciation on our property and equipment. We depreciate our assets over their estimated useful life. We estimate
leasehold improvements to have a estimated useful life over the term of the lease or the estimated useful life, whichever is shorter; computer equipment to have a 2-year life;
software to have a 3-year life, machinery and equipment to have a 2 to 5 year life and furniture and office equipment to have a 2 to 7 year life.

Accounting for warrants

We issued warrants to purchase shares of common stock related to equity transactions in 2017, 2018, and 2019. We account for our warrants issued in accordance with
Accounting  Standards  Codification  (ASC)  Topic  815,  Derivatives  and  Hedging,  guidance  applicable  to  derivative  instruments,  which  requires  every  derivative  instrument
within  its  scope  to  be  recorded  on  the  balance  sheet  as  either  an  asset  or  liability  measured  at  its  fair  value,  with  changes  in  fair  value  recognized  in  earnings  for  liability
classified warrants. Based on this guidance, we determined that certain of our warrants to purchase shares of common stock related to equity transactions in 2017, 2018 and
2019  meet  the  criteria  for  classification  as  a  liability. Accordingly,  the  warrants  were  classified  as  a  warrant  liability  and  are  subject  to  fair  value  remeasurement  at  each
transaction and balance sheet date. The fair value was estimated using the Black-Scholes option pricing model, based on the market value of the underlying common stock at the
measurement date, the contractual term of the warrant, risk-free interest rates, expected dividends and expected volatility of the price of the underlying common stock.

Our financial instruments consist primarily of non-trade receivables, account payables, accrued expenses, and a warrant liability. The carrying amount of non-trade

receivables, accounts payables, and accrued expenses approximates their fair value because of the short-term maturity of such.

We have categorized our assets and liabilities that are valued at fair value on a recurring basis into three-level fair value hierarchy in accordance with GAAP. Fair
value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset
or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets
for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3).

Assets and liabilities recorded in the balance sheets at fair value are categorized based on a hierarchy of inputs as follows:

Level 1 - Unadjusted quoted prices in active markets of identical assets or liabilities.
Level  2  -  Quoted  prices  for  similar  assets  or  liabilities  in  active  markets  or  inputs  that  are  observable  for  the  asset  or  liability,  either  directly  or  indirectly  through

market corroboration, for substantially the full term of the financial instrument.

Level 3 - Unobservable inputs for the asset or liability.

53

 
 
 
 
Our  financial  assets  and  liabilities  recorded  at  fair  value  on  a  recurring  basis  include  the  fair  value  of  our  warrant  liability  discussed  below.  The  fair  value  of  this
warrant liability associated with the February 2017, February 2018, June 2018, March 2019, and April 2019 Offerings ("Offerings") are included in long-term liabilities on the
accompanying financial statements as of December 31, 2019. As of December 31, 2018, the fair value of the warrant liability associated with the February 2017 Offering was
included in current liabilities, and the liabilities associated with the other offerings were included in long-term liabilities.

We  estimated  the  fair  value  of  the  warrant  liability  issued  in  our  Offerings  under ASC  820  as  of  their  issuance  date  for  financial  reporting  purposes.  We  used  the
Black-Scholes option pricing model (“BSM”) to determine the fair value of the warrants. The BSM model is acceptable in accordance with GAAP. The BSM requires the use of
a number of assumptions including volatility of the stock price, the weighted average risk-free interest rate, and the weighted average term of the Warrant.

The risk-free interest rate assumption is based upon observed interest rates on zero coupon US Treasury bonds whose maturity period is appropriate for the term of the

warrants and is calculated by using the average daily historical stock prices through the day preceding the grant date.

Estimated volatility is a measure of the amount by which our stock price is expected to fluctuate each year during the expected life of the warrants. Where appropriate,
we used the historical volatility of peer entities combined with our own due to the lack of sufficient historical data of our stock price during 2017-2019. In 2019 we began
utilizing some our stock's own volatility in the estimated volatility in the BSM. Beginning in 2020, only the volatility of our stock will be used in the BSM as we now have
sufficient historic data in our stock price.

Changes in the fair value during the accounting period are shown as other income or expense.

Stock-based compensation

Stock based compensation transactions are recognized as compensation expense in the statement of operations based on their fair values on the date of the grant, with
the compensation expense recognized over the period in which a grantee is required to provide service in exchange for the award. We estimate the fair value of options granted
using the Black-Scholes option valuation model, and the fair value of restricted stock units using the closing price of our common stock as reported on the date of grant. The
Black-Scholes estimate uses assumptions regarding a number of inputs that require us to make significant estimates and judgments. In 2019 we began utilizing some our stock's
own volatility in the estimated volatility in the BSM. Beginning in 2020, only the volatility of our stock will be used in the BSM as we now have sufficient historic data in our
stock price.

Income taxes

We account for income taxes using ASC 740 Income Taxes. ASC 740 Income Taxes is an asset and liability approach that requires the recognition of deferred tax
assets  and  liabilities  for  the  expected  future  tax  consequences  of  events  that  have  been  recognized  in  our  financial  statements  or  tax  returns.  In  estimating  future  tax
consequences, ASC 740 generally considers all expected future events other than enactments of and changes in the tax law or rates. The measurement of deferred tax assets is
reduced, if necessary, by the amount of any tax benefits that, based on available evidence, are not expected to be realized. Valuation allowances are provided if, considering
available evidence, it is more likely than not that the deferred tax assets will not be realized. ASC 740 clarifies the criteria that must be met prior to recognition of the financial
statement benefit of a position taken in a tax return. ASC 740 provides a benefit recognition model with a two-step approach consisting of “more-likely-than-not” recognition
criteria,  and  a  measurement  attribute  that  measures  a  given  tax  position  as  the  largest  amount  of  tax  benefit  that  is  greater  than  50%  likely  of  being  realized  upon  ultimate
settlement. ASC  740  also  requires  the  recognition  of  liabilities  created  by  differences  between  tax  positions  taken  in  a  tax  return  and  amounts  recognized  in  the  financial
statements.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures.

Our management, including our principal executive officer and principal financial officer, has evaluated the effectiveness of the design and operation of our disclosure
controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this Form 10-K. Based on this evaluation,
our  Chief  Executive  Officer  ("CEO")  and  our  Chief  Financial  Officer  ("CFO"),  concluded  that  as  a  result  of  the  material  weakness  in  our  internal  controls  over  financial
reporting discussed below, our disclosure controls and procedures were not effective at ensuring that information required to be disclosed in the reports we file or submit under
the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms and that
such  information  is  accumulated  and  communicated  to  our  management,  including  our  principal  executive  and  principal  financial  officers,  or  persons  performing  similar
functions, as appropriate to allow timely decisions regarding disclosure.

Attestation Report of the Registered Public Accounting Firm

Our independent registered public accounting firm will not be required to formally attest to the effectiveness of our internal controls over financial reporting for as long

as we are an "emerging growth company" pursuant to the provisions of the Jumpstart Our Business Startups Act.

Management's Report on Internal Control Over Financial Reporting

Our principal executive officer and our principal accounting and financial officer, are responsible for establishing and maintaining adequate internal control over

financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Management conducted an assessment of the effectiveness of our internal control over financial
reporting as of December 31, 2019. In making this assessment, management used the criteria described in Internal Control-Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our management concluded that our internal controls over financial reporting were, and
continue to be ineffective, as of December 31, 2019 due to a material weakness in our internal controls due to the lack of segregation of duties as described below:

•

•

Due to our size and nature, segregation of all conflicting duties may not always be possible and may not be economically feasible, however segregation of duties has
been implemented, with regards to the initiation of transactions, the custody of assets and the recording of transactions performed by separate individuals.
A  number  of  the  prior  issues  related  to  segregation  of  duties  were  remediated  with  new  information  technology  systems  and  policies  during  2019  and  further
improvements are planned for 2020.

It should be noted that any system of controls, however well designed and operated, can provide only reasonable and not absolute assurance that the objectives of the
system  are  met.  In  addition,  the  design  of  any  control  system  is  based  in  part  upon  certain  assumptions  about  the  likelihood  of  certain  events.  Because  of  these  and  other
inherent limitations of control systems, there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of
how remote.

55

 
 
 
 
 
 
In light of the material weakness described above, we performed additional analysis and other post-closing procedures to ensure our financial statements were prepared
in accordance with generally accepted accounting principles. Accordingly, we believe that the financial statements included in this report fairly present, in all material respects,
our financial condition, results of operations and cash flows for the periods presented.

Management evaluated the impact of our failure to maintain effective segregation of duties on our assessment of our internal control over financial reporting and has
concluded that the control deficiency represents a material weakness. Management added additional accounting and IT personnel in 2019 and implemented a new accounting
software  system,  accounting  policies,  and  banking  controls.  Management  intends  to  further  enhance  its  accounting  staff  and  enhance  the  controls  surrounding  its  system  of
financial accounting and reporting, as soon as economically feasible and sustainable, to further remediate this material weakness.

There has been no change in our internal control over financial reporting, other than what is described above, that has materially affected, or is reasonably likely to

materially affect, our internal control over financial reporting.

ITEM 9B. OTHER INFORMATION.

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or
proceeding brought our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors or officers to us or our stockholders, (iii) any action
asserting a claim against us arising pursuant to any provision of the Delaware General Corporation Law, or our certificate of incorporation or the bylaws, and (iv) any action
asserting a claim against us governed by the internal affairs doctrine. This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act
or Securities Act.

This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers
or  other  employees,  which  may  discourage  such  lawsuits  against  us  and  our  directors,  officers  and  employees. Alternatively,  a  court  could  find  these  provisions  of  our
certificate  of  incorporation  to  be  inapplicable  or  unenforceable  in  respect  of  one  or  more  of  the  specified  types  of  actions  or  proceedings,  which  may  require  us  to  incur
additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Moleculin Biotech, Inc.

Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of Moleculin Biotech, Inc. (a Delaware corporation) and subsidiary (the “Company”) as of December 31,
2019  and  2018,  the  related  consolidated  statements  of  operations  and  comprehensive  loss,  stockholders’  equity,  and  cash  flows  for  each  of  the  two  years  in  the  period
ended December 31, 2019, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material
respects, the financial position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the two years in the period
ended December 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Going Concern
The  accompanying  financial  statements  have  been  prepared  assuming  that  the  Company  will  continue  as  a  going  concern.  As  discussed  in  Note  2  to  the  financial
statements, the Company has incurred an accumulated deficit of $39.6 million since inception and has not generated any revenue from operations. These conditions, along
with other matters as set forth in Note 2, raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters
are also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for opinion
These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on
our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent
with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the
PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an
audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the
purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures
that respond to those risks. Such procedures included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our audits
also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall  presentation  of  the  financial
statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ GRANT THORNTON LLP

We have served as the Company’s auditor since 2017.

1. Nature of Business

Moleculin Biotech, Inc.
Notes to the Consolidated Financial Statements

The  terms  “MBI”  or  “the  Company”,  “we”,  “our”  and  “us”  are  used  herein  to  refer  to  Moleculin  Biotech,  Inc.  MBI  is  a  clinical-stage  pharmaceutical  company,
organized as a Delaware corporation in July 2015, with its focus on the treatment of highly resistant cancers via the development of its oncology drug candidates, all of which
are  based  on  license  agreements  with  The  University  of  Texas  System  on  behalf  of  the  MD Anderson  Cancer  Center,  which  we  refer  to  as  MD Anderson.  MBI  formed
Moleculin Australia  Pty.  Ltd.,  ("MAPL"),  a  wholly  owned  subsidiary  in  June  2018,  to  begin  preclinical  development  in Australia  for  WP1732,  an  analog  of  WP1066.  This
enables the Company to enjoy the benefits of certain research and development tax credits in Australia. In February 2019, the Company entered into an agreement with Animal
Life  Sciences,  LLC  ("ALI"),  where  the  Company  has  granted  a  sublicense  to  ALI  to  research,  develop,  make,  have  made,  use,  offer  to  sell,  sell,  export  or  import  and
commercialize certain licensed products for non-human use and share development data. ALI issued to the Company a  10% interest in ALI. ALI converted into a corporation
and became Animal Life Sciences, Inc.

Core Technologies - MBI has three core technologies with six drug candidates, all of which are based on discoveries made at MD Anderson. These core technologies
are  1) Annamycin,  2)  its  STAT3  Immune/Transcription  Modulators,  or  simply  "Immune/Transcription  Modulators"  WP1066  portfolio  and  3)  its  Metabolism/Glycosylation
Inhibitor portfolio, WP1122. The Company’s clinical stage drugs are Annamycin, an anthracycline which is in two Phase 1/2 studies for the treatment of relapsed or refractory
acute myeloid leukemia ("AML"), WP1066, an Immune/Transcription Modulator, which is in a Phase 1 clinical trial in the US for the treatment in glioblastoma, and WP1220, a
member of the WP1066 portfolio of drugs, which has completed a Phase 1 proof-of-concept clinical trial for the topical treatment of cutaneous T-cell lymphoma ("CTCL"), a
form of skin cancer. A fifth Phase 1 trial for the treatment of pediatric brain tumors at Emory University has been approved by the US Food and Drug Administration ("FDA")
and is expected to begin in 2020.

The Company believes Annamycin is a "Next Generation Anthracycline" since it is designed to avoid multidrug resistance mechanisms that typically defeat currently
approved anthracyclines, as well as to be non-cardiotoxic, which is the dose limiting toxicity of all currently approved anthracyclines. Annamycin is currently in two Phase 1/2
clinical trials, and preliminary clinical data suggests that it may have the potential to become the first therapy suitable for the majority of relapsed or refractory AML patients
regardless of gene mutations. During 2019, these trials have so far demonstrated the safety, including little to no cardiotoxicity, and has begun to show some initial efficacy.
Additionally,  preclinical  research  in  animal  models  at  MD Anderson  demonstrated  that Annamycin  is  able  to  significantly  improve  survival  in  an  aggressive  form  of  triple
negative breast cancer metastasized to the lungs. Coupled with research demonstrating that Annamycin is capable of accumulating in the lungs at very high levels, this suggests
that Annamycin may be well suited to become a treatment for lung-localized tumors.

WP1066  is  one  of  several  Immune/Transcription  Modulators  that  appear  capable  of  stimulating  immune  response  to  tumors  by  inhibiting  the  errant  activity  of
Regulatory T-Cells ("TRegs") while also inhibiting key oncogenic transcription factors, including p-STAT3, c-Myc and HIF-1α. These transcription factors are widely sought
targets that may also play a role in the lack of efficacy of immune checkpoint inhibitors in certain resistant tumors. The Phase 1 trial for WP1220 demonstrated safety and
efficacy and is being studies for a Phase 2 trial going forward.

The  Company  is  also  developing  new  prodrugs  to  exploit  the  potential  uses  of  inhibitors  of  glycolysis.  Its  lead  Metabolism/Glycosylation  Inhibitor  compound,
WP1122, provides an opportunity to cut off the fuel supply of tumors by taking advantage of their overdependence on glucose as compared with healthy cells. New research
also points to the potential for the glucose decoy ("2-DG") within WP1122 to be capable of enhancing the usefulness of checkpoint inhibitors. In March 2020, we entered into an
agreement with an outside research center who will conduct research on WP1122 for antiviral properties against a range of viruses, including Coronavirus.

Drug  Candidates  - Within  the  Company's  core  technologies,  it  currently  has six  drug  candidates  representing three  substantially  different  approaches  to  treating
cancer. Annamycin is a chemotherapy designed to inhibit the replication of DNA of rapidly dividing cells and is the Company's most mature drug candidate. Annamycin had
been  in  clinical  trials  pursuant  to  an  investigational  new  drug  application  or  IND  that  had  been  filed  with  the  FDA.  Due  to  a  lack  of  development  activity  by  a  prior  drug
developer, this IND was terminated. To permit the renewed investigation of Annamycin, the Company resubmitted a new IND for a Phase 1/2 trial for the treatment of relapsed
or refractory AML in 2017, which the FDA allowed to go into effect in September 2017. The Company has trials opened in the US and Poland. The US Phase 1 portion of the
Phase 1/2 trial reached key safety end points in early 2020 and the Company plans to discuss next steps with the FDA. The Phase 1/2 trial in Poland continues its dose escalation
and is in its fourth cohort. So far both trials have proven Annamycin, to date, is safe and is non-cardiotoxic. The trials have demonstrated initial efficacy as well.

68

The Company has five other drug development projects, two of which are also in clinical trials:

• WP1066 has an approved physician-sponsored clinical trial open for enrollment and dosing patients for the treatment of brain tumors and is close to having a second

Phase 1 trial for another physical-sponsored clinical trial for the potential treatment of pediatric brain tumors, as well as AML and pancreatic cancer,

• WP1220 is an analog of WP1066 for which Polish authorities approved the Company's Clinical Trial Application (CTA) in 2019 for a Phase 1"proof-of-concept"
clinical trial to study the topical treatment of CTCL, which was completed and demonstrated sufficient efficacy to justify, the Company believes, moving to a Phase 2 trial in the
near future,

• WP1732, another analog of WP1066, is being evaluated along with WP1066 for the potential treatment of AML, pancreatic and other cancers, and MBI has begun
pre-clinical work that it expects to generate sufficient data for an IND for an intravenous formulation of one of its STAT3 inhibitors, which filing is expected to be submitted in
2021, and

• WP1122 and WP1234 are being evaluated for their potential to treat brain tumors and pancreatic cancer via their ability to inhibit glycolysis.

Clinical  Trials  - The Company has concluded the initial Phase 1 portion of its Phase 1/2 trial in the US due to the FDA’s requirement to set the initial dose level
relatively low in comparison with previous Annamycin clinical trials. Additionally, the Company believes that patient recruitment for its clinical trial in Poland will be more
successful than in the US due to a comparatively lower number of competitive clinical trials and the protocol there being approved to start at a significantly higher dose than in
the US with fewer enrollment screening limitations. This trial is in its fourth cohort in the dose ranging Phase 1 portion of the trial. In September 2018, the physician sponsored
WP1066 Phase I clinical trial for the treatment of glioblastoma and melanoma metastasized to the brain, which opened for recruitment in July 2018, began treating patients. In
August 2019, the Company completed its proof-of-concept Phase 1 clinical trial in Poland to study WP1220, a part of the WP1066 portfolio, for the treatment of CTCL. This
trial demonstrated the safety of WP1220 and also demonstrated initial efficacy sufficient, the Company believes, to move forward into a Phase 2 trial.

Licenses - The Company has been granted royalty-bearing, worldwide, exclusive licenses for the patent and technology rights related to all of MBI's drug technologies,
as  these  intellectual  property  rights  are  owned  in  part  or  entirely  by  MD Anderson.  The Annamycin  drug  substance  is  no  longer  covered  by  any  existing  patent  protection,
however, the Company filed new patent applications in July 2019 for formulation, synthetic process and reconstitution related to MBI's Annamycin drug product candidate,
although there is no assurance that the Company will be successful in obtaining such patent protection. Such technology is also licensed from MD Anderson. Independently
from  potential  patent  protection,  MBI  has  received  Orphan  Drug  designation  ("ODD")  from  the  FDA  for Annamycin  for  the  treatment  of AML  and  for  WP1066  for  the
treatment of glioblastoma. ODD may provide tax and other benefits during product development, and if either product is approved, may lead to a grant of seven-year market
exclusivity.  Under  that  exclusivity,  which  runs  from  the  date  of  the  approval  of  the  New  Drug Application  ("NDA")  in  the  United  States,  the  FDA  generally  (there  are
important exceptions) could not approve another product containing the same drug for the designated indication. The Company also intends to apply for similar status in the
European Union ("EU") where market exclusivity could extend to 10 years from the date of Marketing Authorization Application ("MAA") approval. Separately, the FDA may
also grant market exclusivity of 5 years for newly approved new chemical entities (which the Company believes Annamycin would be one), which would preclude approval of
any  other  annamycin  product,  but  there  can  be  no  assurance  that  such  exclusivity  will  be  granted.  In April  2019,  FDA  approved  the  Company's  request  for  Fast  Track
Designation for Annamycin for the treatment of relapsed or refractory AML. Fast Track Designation, the purpose of which is to expedite drug development and approval, is
granted to drugs intended to treat serious conditions and where data demonstrate the potential to address an unmet medical need.

2. Basis of presentation, principles of consolidation and significant accounting policies

Basis of Presentation - The accompanying consolidated financial statements and related notes have been prepared in accordance with accounting principles generally
accepted  in  the  United  States  of America  (“U.S.  GAAP”)  for  financial  information,  and  in  accordance  with  the  rules  and  regulations  of  the  United  States  Securities  and
Exchange Commission (the “SEC”).

Principles  of  consolidation  -  The  accompanying  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its  wholly  owned  subsidiary.  All
intercompany  balances  and  transactions  have  been  eliminated  in  consolidation.  The  company  views  its  operations  and  manages  its  business  in  one  operating  segment. All
material long-lived assets of the

69

 
Company reside in the United States. In accordance with FASB ASC Topic 280, Segment Reporting, we view our operations and manage our business as one  segment. As  a
result, the financial information disclosed herein represents all of the material financial information related to our principal operating segment.

Use  of  Estimates  -  The  preparation  of  these  consolidated  financial  statements  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported
amounts of assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those
estimates. Management considers many factors in selecting appropriate financial accounting policies and controls, and in developing the estimates and assumptions that are used
in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected
business  and  operational  changes,  sensitivity  and  volatility  associated  with  the  assumptions  used  in  developing  estimates,  and  whether  historical  trends  are  expected  to  be
representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes and management must select
an amount that falls within that range of reasonable estimates. This process may result in actual results differing materially from those estimated amounts used in the preparation
of financial statements. Estimates are used in the following areas, among others: fair value estimates on intangible assets, warrants, and stock-based compensation expense, as
well as accrued expenses and taxes.

Going Concern - These consolidated financial statements have been prepared on a going concern basis, which assumes the Company will continue to realize its assets
and  discharge  its  liabilities  in  the  normal  course  of  business.  The  continuation  of  the  Company  as  a  going  concern  is  dependent  upon  the  ability  of  the  Company  to  obtain
necessary financing to continue operations and the attainment of profitable operations. As of December 31, 2019, the Company has incurred a consolidated accumulated deficit
of  $39.6  million  since  inception  and  had  not  yet  generated  any  revenue  from  operations. Additionally,  management  anticipates  that  its  consolidated  cash  on  hand  as  of
December 31, 2019 plus the additional cash generated from its equity offering subsequent to year-end, discussed further in Note 9. Subsequent Events, within these notes to the
consolidated financial statements, is sufficient to fund its planned operations into but not beyond the near term. These factors raise substantial doubt regarding the Company’s
ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts
and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company may seek additional funding through a
combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements, other collaborations,
strategic alliances and licensing arrangements and delay planned cash outlays or a combination thereof. Management cannot be certain that such events or a combination thereof
can be achieved.

Cash and Cash Equivalents - The Company considers all highly liquid accounts with original maturities of three months or less at the date of acquisition to be cash

equivalents. Periodically in the ordinary course of business, the Company may carry cash balances at financial institutions in excess of the insured limits of $250,000.

Prepaid Expenses and Other Current Assets - Prepaid expenses and other current assets consist of the following (in thousands):

Vendor prepayments and deposits
Prepaid insurance
Non-trade receivables
Related party receivables
Other

Vendor prepayments includes approximately $1.5 million for the expansion of Annamycin production commitments on a commercial scale to be delivered in 2020,

which will be used in clinical trials.

Property and equipment - Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line depreciation method as

follows:

Software
Machinery and equipment
Furniture and office equipment

to 5 years
to 7 years

Intangible assets - Intangible assets with finite lives are amortized using the straight-line method over their estimated period of benefit. Acquired intangible assets
identified  as  in-process  research  and  development  ("IPR&D")  assets,  are  considered  indefinite  lived  until  the  completion  or  abandonment  of  the  associated  research  and
development  efforts.  If  the  associated  research  and  development  effort  is  abandoned,  the  related  IPR&D  assets  will  be  written-off  and  the  Company  will  record  a  noncash
impairment loss on its statements of operations. For those compounds that reach commercialization, the IPR&D assets will be amortized over their estimated useful lives. We
evaluate  the  recoverability  of  intangible  assets  periodically  and  take  into  account  events  or  circumstances  that  warrant  revised  estimates  of  useful  lives  or  that  indicate  that
impairment exists. No impairments of intangible assets have been identified during any of the periods presented. Intangible assets are tested for impairment on an annual basis,
and between annual tests if indicators of potential impairment exist, using a fair-value-based approach.

Operating Lease Right-of-Use Asset - The Company determines if an arrangement is a lease at contract inception or during modifications or renewal of an existing
lease. Operating lease assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent the Company's obligation to
make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease
payments over the lease term. The lease payments used to determine the Company's operating lease assets may include lease incentives, stated rent increases and escalation
clauses linked to rates of inflation when determinable and are recognized in the Company's operating lease assets in the Company's condensed consolidated balance sheet. The
Company has elected the practical expedient and does not separate lease components from nonlease components for its leases. The Company's operating leases are reflected in
operating lease right-of-use asset ("ROU"), accrued expenses and other current liabilities, and operating lease liability - long-term in the Company's consolidated balance sheets.
Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Short-term leases, defined as leases that have a lease term of 12 months or
less at the commencement date, are excluded from this treatment and are recognized on a straight-line basis over the term of the lease. Refer to Note 8 - Commitments and
Contingencies - Lease Obligations Payable for additional information related to the Company’s operating leases.

Cost Method Investment - The Company's cost method investment consists of an investment in a private company in which it does not have the ability to exercise

significant influence over its operating and financial activities. Management evaluates this investment for possible impairment quarterly.

Fair  Value  of  Financial  instruments  - The  Company's  financial  instruments  consist  primarily  of  non-trade  receivables,  account  payables,  accrued  expenses  and  a
warrant liability. The carrying amount of non-trade receivables, accounts payables, and accrued expenses approximates their fair value because of the short-term maturity of
such. The Company has categorized its assets and liabilities that are valued at fair value on a recurring basis into three-level fair value hierarchy in accordance with GAAP. Fair
value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset
or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy gives the highest priority to quoted prices in active markets
for identical assets and liabilities (Level 1) and lowest priority to unobservable inputs (Level 3).

Assets and liabilities recorded in the balance sheets at fair value are categorized based on a hierarchy of inputs as follows:

Level 1 – Unadjusted quoted prices in active markets of identical assets or liabilities.
Level 2 – Quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through

market corroboration, for substantially the full term of the financial instrument.

Level 3 – Unobservable inputs for the asset or liability.

The Company’s financial assets and liabilities recorded at fair value on a recurring basis include the fair value of our warrant liability discussed in Note 5.

The following table provides the financial assets and liabilities reported at fair value and measured on a recurring basis at December 31, 2019 and 2018 (in thousands):

The  above  table  of  Level  3  liabilities  begins  with  the  valuation  as  of  December  31,  2017  and  adjusts  the  balances  for  changes  that  occurred  during  the  years.  The
ending balance of the Level 3 financial instrument presented above represent our best estimates and may not be substantiated by comparison to independent markets and, in
many cases, could not be realized in immediate settlement of the instruments.

Income Taxes - The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined
based on the differences between the financial reporting and the tax bases of reported assets and liabilities and are measured using the enacted tax rates and laws that will be in
effect when the differences are expected to reverse. The Company must then assess the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is
provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized.

The  Company  accounts  for  uncertain  tax  positions  in  accordance  with  the  provisions  of ASC  740-10  which  prescribes  a  recognition  threshold  and  measurement
attribute for financial statement disclosure of tax positions taken, or expected to be taken, on its tax return. The Company evaluates and records any uncertain tax positions
based on the amount that management deems is more likely than not to be sustained upon examination and ultimate settlement with the tax authorities in the tax jurisdictions in
which it operates.

Translation of Foreign Currencies - The functional currency for our foreign subsidiary is the local currency. For our non-U.S.subsidiary that transacts in a functional
currency other than the U.S. dollar, assets and liabilities are translated at current rates of exchange at the balance sheet date. Income and expense items are translated at the
average foreign currency rates for the period. Adjustments resulting from the translation of the financial statements of our foreign operations into U.S. dollars are excluded from
the determination of net income and are recorded in accumulated other comprehensive income, a separate component of equity.

Stock-based Compensation - Stock-based compensation expense includes the estimated fair value of equity awards vested or expected to vest during the reporting
period. The Company accounts for its stock-based compensation awards in accordance with FASB ASC Topic 718, Compensation—Stock Compensation (“ASC 718”). ASC
718 requires all stock-based

72

   
 
 
 
 
 
 
 
 
payments to employees, including grants of employee stock options, restricted stock units, and modifications to existing stock options, to be recognized in the consolidated
statements of operations based on their fair values. The grant date fair value of stock options is determined using the Black-Scholes option pricing model and the grant date fair
value of restricted stock awards is determined using the closing price of the Company’s common stock on the date of grant. The awards are subject to service vesting conditions.
Compensation expense related to awards to employees and directors with service-based vesting conditions is recognized on a straight-line basis based on the grant date fair
value over the associated service period of the award, which is generally the vesting term. Compensation expense related to awards to non-employees with service-based vesting
conditions is recognized based on the then-current fair value at each financial reporting date prior to the measurement date over the associated service period of the award,
which is generally the vesting term.

Loss Per Common Share - Basic net loss per common share is computed by dividing net loss available to common shareholders by the weighted-average number of
common  shares  outstanding  during  the  period.  For  purposes  of  this  calculation,  options  to  purchase  common  stock,  restricted  stock  units  subject  to  vesting  and  warrants  to
purchase common stock were considered to be common stock equivalents. Diluted net loss per common share is determined using the weighted-average number of common
shares  outstanding  during  the  period,  adjusted  for  the  dilutive  effect  of  common  stock  equivalents.  In  periods  when  losses  are  reported,  the  weighted-average  number  of
common  shares  outstanding  excludes  common  stock  equivalents,  because  their  inclusion  would  be  anti-dilutive.  For  the  years  ended  December  31,  2019,  and  2018,
approximately 12.2 million and approximately 5.4 million, respectively, of potentially dilutive shares were excluded from the computation of diluted earnings per share due to
their antidilutive effect.

Research and Development Costs - Research and development costs are expensed as incurred.

Reclassifications - A reclassification was made to the prior period financial statements to conform to the 2019 presentation. Such reclassification did not affect net loss

as previously reported.

Subsequent Events - The Company’s management reviewed all material events through the date these consolidated financial statements were issued for subsequent

event disclosure consideration as described in Note 9.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases ("Topic 842") ("ASU 2016-02"). Under ASU 2016-02, an entity will be required to recognize right-of-
use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a
lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of
the  financial  statements  to  assess  the  amount,  timing  and  uncertainty  of  cash  flows  arising  from  leases.  The  Company  adopted  this  standard  on  January  1,  2019  using  the
modified retrospective transition method. Therefore, prior period financial information before adoption has not been adjusted and continues to be reflected in accordance with
the Company's historical accounting policy. Upon adoption, the Company recognized a ROU asset of $0.1 million, an operating lease liability of $0.2 million and there was no
cumulative-effect adjustment to the opening balance of retained earnings as of January 1, 2019. The standard establishes a ROU asset model that requires the lessee to recognize
a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. (see Note 8 Commitments and Contingencies)

In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718) Improvements to

Non-employee Share-Based Payment Accounting ("ASU 2018-07"). ASU 2018-07 affects all entities that enter into share-based payment transactions for acquiring goods and
services from non-employees. The amendments in this ASU expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from
non-employees. The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that
fiscal year. Early adoption permitted, but no earlier than an entity's adoption date of Topic 606. The Company adoption of this pronouncement effective January 1, 2018 did not
have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820) ("ASU 2018-13"). ASU 2018-13 modifies the disclosure requirements on
fair  value  measurements  in  Topic  820,  Fair  Value  Measurement,  based  on  the  concepts  in  the  Concepts  Statement,  including  the  consideration  of  costs  and  benefits.  The
amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company adoption
of this pronouncement effective January 1, 2018 did not have a material impact on the Company's consolidated financial statements.

In  December  2019,  the  FASB  issued ASU  No.  2019-12,  Income  Taxes  (Topic  740)  ("ASU  2019-12"). ASU  2019-12  modifies  the  requirements  for  the  timing  of
adoption  of  enacted  change  in  tax  law.  The  effects  of  changes  on  taxes  currently  payable  or  refundable  for  the  current  year  must  be  reflected  in  the  computation  of  annual
effective  tax  rate  in  the  first  interim  period  that  includes  the  enactment  date  of  the  new  legislation,  beginning  after  December  15,  2020.  Early  adoption  is  permitted  upon
issuance of this ASU. The Company is currently evaluating the impact that this standard will have, if any, on its financial statements.

The  Company  does  not  believe  that  any  other  recently  issued  effective  pronouncements,  or  pronouncements  issued  but  not  yet  effective,  if  adopted,  would  have  a

material effect on the accompanying financial statements.

3. Intangible Assets

In  conjunction  with  its  acquisition  of  Moleculin,  LLC  in  2016,  the  Company  recognized  an  intangible  asset  for  acquired  in-process  research  and  development
(“IPR&D) related to the acquired WP1066 portfolio. As our WP1066 portfolio is currently in development, the Company’s IPR&D intangible asset will not be amortized until
development is complete. If the associated research and development effort is abandoned, the Company’s IPR&D intangible asset will be written-off and the Company will
record a noncash impairment loss on its statements of operations. For those compounds that reach commercialization, the IPR&D assets will be amortized over their estimated
useful lives. IPR&D was $11.1 million as of December 31, 2019 and 2018, respectively.

4.  Accrued expenses and other current liabilities

Accrued expenses and other current liabilities at December 31, 2019 and 2018 consist of the following components (in thousands):

Upon its issuance of warrants to purchase shares of common stock, the Company evaluates the terms of the warrant issue to determine the appropriate accounting and

classification of the warrant issue pursuant to FASB ASC Topic 480, Distinguishing Liabilities from Equity, FASB ASC Topic 505, Equity, FASB ASC 815, Derivatives and
Hedging, and ASC 718. Warrants are classified as liabilities when the Company may be required to settle a warrant exercise in cash and classified as equity when the Company
settles a warrant exercise in shares of its common stock.

Liability classified warrants are valued at fair value at the date of issue and at each reporting date pursuant to FASB ASC 820, Fair Value Measurement, (“ASC 820”)
and is reflected as a warrant liability on our consolidated balance sheet with the change in the warrant liability during each reporting period is reflected as a gain (loss) from
change in fair value of warrant liability in our consolidated statement of operations.

Equity classified warrants issued to non-employees in exchange for services are accounted for in accordance with ASC 718 which requires all stock-based payments be
recognized  in  the  consolidated  statements  of  operations  based  on  their  fair  value.  For  further  information,  see  Note  2.  Basis  of  presentation,  principles  of  consolidation  and

(1) If the Company subdivides (by any stock split, stock dividend, recapitalization or otherwise) its outstanding shares of its common stock into a smaller number of
shares, the warrant exercise price is proportionately reduced and the number of shares under outstanding warrants is proportionately increased. Additionally, if the Company
combines  (by  combination,  reverse  stock  split  or  otherwise)  its  outstanding  shares  of  common  stock  into  a  smaller  number  of  shares,  the  warrant  exercise  price  is
proportionately increased and the number of shares under outstanding warrants is proportionately decreased. Also, the Company may voluntarily reduce the warrant exercise
price for its warrants issued in March 2019 and February 2017 and may voluntarily extend the contractual term of its warrants issued in February 2017.

(2)  Includes  warrants  to  purchase 710,212  shares  at  an  exercise  price  of  $2.02,  expiring  December  22,  2023,  and  warrants  to  purchase 32,779  shares  at  an  exercise

price of $2.32, expiring June 21, 2023.

(3) Includes warrants to purchase 100,000 shares at an exercise price of $2.41 and warrants to purchase 50,000 shares at an exercise price of $3.00.

Liability Classified Warrants

The Company uses the Black-Scholes option pricing model to determine the fair value of its warrants at the date of issue and outstanding at each reporting date.

The  risk-free  interest  rate assumption  is  based  upon  observed  interest  rates  on  zero  coupon  U.S.  Treasury  bonds  linearly  interpolated  to  obtain  a  maturity  period

commensurate with the term of the warrants.

Estimated volatility is a measure of the amount by which the Company's stock price is expected to fluctuate each year during the expected life of the warrants. Where
appropriate, the Company uses the historical volatility of peer entities combined with our own common stock due to the lack of sufficient historical data of our stock price
during the years 2017 to 2019.

The assumptions used in determining the fair value of the Company’s outstanding liability classified warrants are as follows:

may sell Shares through the Agent by any method that is deemed an “at the market offering” as defined in Rule 415 under the Securities Act of 1933, as amended. Sales of the
Shares, if any, may be made at market prices prevailing at the time of sale, subject to such other terms as may be agreed upon at the time of sale, including a minimum sales
price that may be stipulated by the Company’s Board of Directors or a duly authorized committee thereof. The Company or the Agent, under certain circumstances and upon
notice to the other, may suspend the offering of the Shares under the Agreement. The offering of the Shares pursuant to the Agreement will terminate upon the sale of Shares in
an  aggregate  offering  amount  equal  to  $15  million,  or  sooner  if  either  the  Company  or  the Agent  terminate  the Agreement  pursuant  to  its  terms.  The  Company  will  pay  a
commission to the Agent of 3.0% of the gross proceeds of the sale of the Shares sold under the Agreement and reimburse the Agent for certain expenses. The Company has also
provided the Agent with customary indemnification rights. The Company has not sold any shares under the Opco Agreement.

Stock Options

Stock option awards are generally granted with an exercise price equal to the market price of the Company’s stock at the date of grant. Stock option awards generally
have  a 10-year  contractual  term  and  vest  over  a 4-year  period  for  employees  and  over  a 1  to 3-year period for directors from the grant date on a straight-line basis over the
requisite  service  period.  The  grant-date  fair  value  of  stock  options  is  determined  using  the  Black-Scholes  option-pricing  model. Additionally,  the  Company’s  stock  options
provide for full vesting of unvested outstanding options, in the event of a change of control of the Company.

The  fair  value  of  each  stock  option  is  estimated  on  the  date  of  grant  using  the  Black-Scholes  option  valuation  model  that  uses  the  assumptions  noted  below.  The
expected term of the stock option awards was computed using the “plain vanilla” method as prescribed by the Securities and Exchange Commission Staff Accounting Bulletin
107 because the Company does not have sufficient data regarding employee exercise behavior to estimate the expected term. The volatility was determined by referring to the
average historical volatility of a peer group of public companies due to the lack of sufficient historical data of its stock price. The risk-free rate for periods within the contractual
life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

The fair value of the option grants has been estimated, with the following weighted-average assumptions:

Risk-free interest rate
Volatility
Expected life (years)
Expected dividend yield

Options granted during 2019 have an aggregated fair value of $1.2 million that was calculated using the Black-Scholes option-pricing model. At December 31, 2019,
total compensation cost not yet recognized was $2.9 million and the weighted average period over which this amount is expected to be recognized is 2.49 years. The aggregate
fair value of options vesting in the years ended December 31, 2019 and 2018 was $1.3 million and $0.8 million, respectively. Cash received from the exercise of stock options
was $5,000 for the year ended December 31, 2019.

Restricted Stock

In July 2019, the Company granted 316,907 restricted stock units, which vest annually in four equal installments. The weighted average grant date fair value of $1.31
per unit was determined using the closing price of the Company’s common stock on the grant date. Prior to 2019, the Company had not granted any restricted stock awards.
Additionally, the Company’s restricted stock unit agreements provide for full vesting of the restricted stock award in the event of a change of control of the Company. During
the year ended December 31, 2019, no restricted stock units vested or were forfeited.

As of December 31, 2019, total compensation cost not yet recognized was $0.4  million  and  the  weighted  average  period  over  which  this  amount  is  expected  to  be

recognized is 3.5 years.

The  Company  has  incurred  net  operating  losses  since  inception. As  of  December  31,  2019,  the  Company  had  total  U.S.  federal  operating  loss  carry  forwards  of
approximately $25.6 million. Of this, $6.0 million will expire commencing in 2035, with the rest having no set expiration date. The value of these carryforwards depends on the
Company’s ability to generate taxable income. Additionally, because federal tax laws limit the time during which the net operating loss carryforwards may be applied against
future taxes, if the Company fails to generate taxable income prior to the expiration dates of the carry forwards the Company may not be able to fully utilize the net operating
loss carryforwards to reduce future income taxes. Under the new tax laws, net operating loss carry forwards will not expire beginning for losses generated in the 2018 tax year.
However, these net operating losses will only be able to offset 80% of future taxable income. Finally, the Company has not undertaken a detailed analysis of the application of
IRC Section 382 with respect to limitations on the utilization of net operating loss carryforwards and other deferred tax assets. However, the Company believes that this matter
is not material to the overall tax position within the financial statements due to the full valuation allowance against the net operating losses and the lack of utilization of the net
operating losses during tax years open under statute.

The  Company  conducts  business  in  various  locations  and,  as  a  result,  files  income  tax  returns  in  the  United  States  Federal  jurisdiction  and  in  multiple  state
jurisdictions. As of December 31, 2019, the Company had state operating losses of approximately $ 0.7 million which expire commencing in 2038. Since the Company is in a
loss  carryforward  position,  the  Company  is  generally  subject  to  examination  by  the  U.S.  federal,  state  and  local  income  tax  authorities  for  all  tax  years  in  which  a  loss
carryforward is available.

Management  has  evaluated  the  positive  and  negative  evidence  for  the  realizability  of  its  deferred  tax  assets.  The  Company  has  cumulative  losses  and  there  is  no
assurance of future taxable income, therefore, valuation allowances have been recorded to fully offset the deferred tax asset at December 31, 2019. Management has determined
that it is more likely than not that the Company will not recognize the benefits of its federal and state deferred tax assets, and as a result, a valuation allowance of $9.4 million
and $5.9 million has been established at December 31, 2019 and 2018, respectively. The change in the valuation allowance for the year ended December 31, 2019 was primarily
due to additional operating losses and capitalized research costs.

The Company undertakes research and development (R&D) activities that qualify for certain tax credits for US and Australian income tax purposes.  The Company has
a full valuation allowance against its U.S. federal R&D tax credits. For the 2018 tax year, the Company claimed an Australian credit of approximately $ 0.2 million on its 2018
Australian tax return. For the 2019 tax year, the potential U.S. and Australian research and development tax credits are not expected to be significant.

The company has a liability for unrecognized tax benefits of $0.1 million (excluding accrued interest and penalties) as of December 31, 2019.

A reconciliation of the beginning and ending unrecognized tax benefits excluding interest and penalties is as follows (in thousands):

2019 within the next year..

8. Commitments and Contingencies

Lease Obligations Payable

Effective January 1, 2019, the Company adopted ASC 842, which requires recognition of a right-of use asset and a lease liability for all leases at the commencement

date based on the present value of the lease payment over the lease term.

In March 2018, the Company entered into a Lease Agreement (the “Lease”) which it uses for its corporate office space and headquarters. The term of the Lease began
in August 2018 and will continue for an initial term of 66 months, which may be renewed for an additional 5 years. The Company is required to remit base monthly rent which
will increase at an average approximate rate of 3% each year. The Company is also required to pay additional rent in the form of its pro-rata share of certain specified operating
expenses of the Landlord. The leased space is located in Houston, Texas. The corporate office lease is classified as an operating lease.

In August 2019, the Company entered into an Amended Lease Agreement (the "Lab Lease") which it uses for lab space. The term of the Lease began in September
2019 and will continue for an initial term of 35 months, with no further right or option to renew. The Company is required to remit base monthly rent which will increase at an
average  approximate  rate  of 3%  each  year.  The  Lab  Lease  is  classified  as  an  operating  lease.  In  August  2019,  the  Company  entered  into  a  sublease  with  Houston
Pharmaceuticals, Inc. ("HPI"). The Company has granted HPI access to all of its Lab Lease space and HPI has agreed to pay the Company 50% of the Company's rent payable
under the Lab Lease less 50% of any benefits from any sublease or other lab service agreement the Company may receive from its Lab Lease. Although HPI has access to the
Company's  Lab  Lease  space,  it  is  the  intent  of  the  parties  that  they  equally  share  the  Lab  Lease  space  for  research  purposes.  The  Company  recorded  approximately  $0.01
million  in  sublease  income  from  the  related  party  for  the  year  ended  December  31,  2019.  Sublease  income  is  recorded  as  other  income  on  the  Company's  condensed
consolidated statement of operations and comprehensive loss. The Company recorded lease costs of $0.06 million for the year ended December 31, 2019.

The Company made an accounting policy election not to apply the recognition requirements  to  short-term  leases.  The  Company  recognizes  the  lease  payments  for
short-term leases in profit or loss on a straight-line basis over the lease term, and variable lease payments in the period in which the obligation for those payments is incurred.
The Company recorded total expenses for its short-term leases of $0.04 million for the year ended December 31, 2019. The Company recorded lease costs for variable lease
payments of $0.03 million for the year ended December 31, 2019.

As of December 31, 2019, the weighted average remaining lease term is 4.17 and 2.58 for the Lease and Lab Lease, respectively, and the weighted average discount
rate  is 9.6%. The interest rate implicit in lease contracts is typically not readily determinable and as such, the Company uses an incremental borrowing rate based on a peer
analysis using information available at the commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a
similar term, an amount equal to the lease payments in a similar economic environment. During the year ended December 31, 2019, in addition to the initial adoption of the
lease standard, the Company amended its Lab Lease which required additional right of use assets and liabilities to be recorded.

Licenses

MD Anderson

Under  agreements  associated  with Annamycin,  the  WP1122  Portfolio,  and  the  WP1066  Portfolio,  which  includes  WP1732,  all  described  below,  the  Company  is
responsible for certain license, milestone and royalty payments over the course of the agreements. Annual license fees can cost as high as $0.1 million depending upon the
anniversary, milestone payments for the commencement of phase II and phase III clinical trials can cost as high as $0.5 million. Other milestone payments for submission of an
NDA to the FDA and receipt of first marketing approval for sale of a license product can be as high as $ 0.6 million. Royalty payments can range in the single digits as a percent
of net sales on drug products or flat fees as high as $0.6 million, depending upon certain terms and conditions. Not all of these payments are applicable to every drug. Total
expenses under these agreements were $0.2 million and $0.3 million, respectively, for the years ended December 31, 2019 and 2018. On June 29, 2017, the Company entered
into an agreement with MD Anderson licensing certain technology related to the method of preparing Liposomal Annamycin.

WP1122 Portfolio

The rights and obligations to an April 2012 Patent and Technology License Agreement entered into by and between IntertechBio and MD Anderson (the “IntertechBio
Agreement”) have been assigned to MBI. Therefore, MBI has obtained a royalty-bearing, worldwide, exclusive license to intellectual property, including patent rights, related to
our WP1122 Portfolio and to our drug product candidate, WP1122.

WP1066 Portfolio

The rights and obligations to a June 2010 Patent and Technology License Agreement entered into by and between Moleculin LLC and MD Anderson (the “Moleculin
Agreement”)  have  been  assigned  MBI.  Therefore,  MBI  has  obtained  a  royalty-bearing,  worldwide,  exclusive  license  to  intellectual  property  rights,  including  patent  rights,
related to its WP1066 drug product candidate. In consideration, the Company must make payments to MD Anderson including an up-front payment, milestone payments and
minimum  annual  royalty  payments  for  sales  of  products  developed  under  the  license  agreement. Annual  Maintenance  fee  payments  will  no  longer  be  due  upon  marketing
approval in any country of a licensed product. One-time milestone payments are due upon commencement of the first Phase III study for a licensed product within the United
States, Europe, China or Japan; upon submission of the first NDA for a licensed product in the United States; and upon receipt of the first marketing approval for sale of a
licensed product in the United States. The rights the Company has obtained pursuant to the assignment of the Moleculin Agreement are made subject to the rights of the U.S.
government to the extent that the

83

technology covered by the licensed intellectual property was developed under a funding agreement between MD Anderson and the U.S. government.

HPI

MBI  entered  into  an  out-licensing  agreement  with  Houston  Pharmaceuticals,  Inc.  (“HPI”),  pursuant  to  which  it  granted  certain  intellectual  property  rights  to  HPI,
including  rights  covering  the  potential  drug  candidate,  WP1066  (“HPI  Out-Licensing Agreement”).  Under  the  HPI  Out-Licensing Agreement  the  Company  was  required  to
make quarterly payments totaling $0.75 million for the first twelve quarters following the effective date of the HPI Out-Licensing Agreement, or May 2, 2016, in consideration
for the right to development data related to the development of licensed products. Notwithstanding the Company's obligation to make the foregoing payments, the HPI Out-
Licensing Agreement did not obligate HPI to conduct any research or to meet any milestones. Upon payment in the amount of $1.0 million to HPI within three years  of  the
effective  date  of  the  HPI  Out-Licensing Agreement  ("HPI  Option  Repurchase  Payment")  MBI  regained  all  rights  to  the  licensed  subject  matter  and  rights  to  any  and  all
development data and any regulatory submissions including any IND, NDA or ANDA related to the licensed subject matter and can end the license without any other obligation
other  than  the  aforementioned  quarterly  payments.  The  option  repurchase  payment  was  paid  on April  30,  2019  for  $1.0  million  and,  accordingly,  the  HPI  Out-Licensing
Agreement was terminated. The $1.0 million payment was accrued and expensed under research and development in 2018. Total expenses related to HPI were $0.1 million and
$1.3 million, for the years ended December 31, 2019 and 2018, respectively. In February 2018, we entered into a license agreement with MD Anderson covering a new group of
molecules recently discovered in connection with research it has been sponsoring, called WP1732, a part of the WP1066 Portfolio. On March 16, 2020, the Company entered
into two agreements with HPI. The first agreement, which has a term of two years, continues a prior consulting arrangement with HPI on the Company's licensed molecules and
requires payments for $0.04 million per quarter to HPI. The second agreement, which can be cancelled with sixty days notice by either party, allows the Company's employees
access to laboratory equipment owned by HPI and this requires a payment of $0.02 million per quarter to HPI.

Sponsored Research Agreements with MD Anderson

In January 2017, MBI amended its Sponsored Laboratory Study Agreement with MD Anderson where it was extended to the end of October 2018. In December 2017,
MBI  extended  this Agreement  until  the  end  of  October  2019  for  total  payment  amount  of  $0.3  million  spread  over  that  period  of  time.  In  September  2018,  the  Company
extended this Agreement until the end of October 2020 for total payment amount of $0.4  million  spread  over  that  period  of  time.  In  June  2019,  the  Company  amended  the
Agreement to support the continuation of the project for total payment amount of $0.4 million. In October 2019, the Company amended the agreement until the end of October
2021 for a total additional payment amount of $0.4 million. The expenses recognized under the MD Anderson agreement with regards to the Sponsored Laboratory Study were
$0.5 million and $0.4 million, respectively for the years ended December 31, 2019 and 2018.

Other Licenses

Dermin

In 2015, we obtained the rights and obligations for certain patent and technology development and license agreements with Dermin Sp. Zoo ("Dermin"). In connection
with such agreements, certain intellectual property rights related to Annamycin, our WP1122 portfolio, and our WP1066 portfolio have been licensed to Dermin and Dermin
has been granted a royalty-bearing, exclusive license to manufacture, have manufactured, use, import, offer to sell and/or sell products in the field of human therapeutics under
the licensed intellectual property. With respect to Annamycin, the license is limited to the countries of Poland, Ukraine, Czech Republic, Hungary, Romania, Slovakia, Belarus,
Lithuania,  Latvia,  Estonia,  Netherlands,  Turkey,  Belgium,  Switzerland,  Austria,  Sweden,  Greece,  Portugal,  Norway,  Denmark,  Ireland,  Finland,  Luxembourg,  Iceland,
Kazakhstan,  Russian  Federation,  Uzbekistan,  Georgia, Armenia, Azerbaijan  and  Germany;  provided  that  we  have  the  right  to  remove  Germany  from  the  list  of  covered
territories  with  a  $0.5  million  payment.  With  respect  to  WP1122,  the  license  is  limited  to  the  countries  of  Belarus,  Russia,  Kazakhstan,  Uzbekistan,  Turkmenistan,  Czech
Republic,  Estonia,  Hungary,  Latvia,  Lithuania,  Poland,  Romania,  Slovakia  and  Ukraine.  With  respect  to  WP1066,  the  license  is  limited  to  the  countries  of  Belarus,  Czech
Republic,  Estonia,  Hungary,  Latvia,  Lithuania,  Poland,  Romania,  Slovakia  and  Ukraine.  In  each  case,  Dermin  will  pay  a  royalty  for  the  sale  of  any  licensed  product  in  the
licensed territories and will pay all out-of-pocket expenses incurred in filing, prosecuting and maintaining the licensed patents for which the license has been granted in the
licensed territories. Dermin also agreed to provide a percentage of certain consideration that Dermin receives pursuant to sublicense agreements. In July 2019, Dermin assigned
its rights under the foregoing license agreements to an affiliated entity, Exploration Invest Pte Ltd. (“Exploration”). On July 30, 2019, the Company and Exploration entered
into a License Modification Agreement pursuant to which the Company agreed to issue Exploration shares of Company common stock valued at $ 0.5 million (based on the
greater of the closing price of the common stock on the date of the agreement or the 10-day average closing price prior to the date of

84

the agreement) in exchange for the modifying the license agreements to: (i) limit the licensed territory solely to Poland; and (ii) limit the patent rights and technology rights
licensed to Exploration to the patent rights and technology rights that existed on the date the original license agreements were entered into with Dermin. In August 2019, the
Company issued 429,978 shares of Company common stock to Exploration to satisfy this commitment.

WPD Pharmaceuticals

In  February  2019,  the  Company  sublicensed  certain  intellectual  property  rights,  including  rights  to Annamycin,  its  WP1122  portfolio,  and  its  WP1066  portfolio  to
WPD Pharmaceuticals sp. z o.o. (“WPD”) (the “WPD Agreement”). WPD is affiliated with Dr. Waldemar Priebe, one of the Company's founders and largest shareholder. Under
the WPD Agreement, the Company granted WPD a royalty-bearing, exclusive license to research, develop, manufacture, have manufactured, use, import, offer to sell and/or sell
products in the field of human therapeutics under the licensed intellectual property in the countries of Germany, Poland, Estonia, Latvia, Lithuania, Belarus, Ukraine, Moldova,
Romania, Armenia, Azerbaijan, Georgia, Slovakia, Czech Republic, Hungary, Uzbekistan, Kazakhstan, Greece, Austria, Russia, Netherlands, Turkey, Belgium, Switzerland,
Sweden, Portugal, Norway, Denmark, Ireland, Finland, Luxembourg, Iceland (“licensed territories”), provided that the Company has the right to buyback Germany from the
licensed territories by making a payment $0.5 million. On July 30, 2019, the Company entered into the aforementioned July 30, 2019 agreement with Dermin that satisfied the
foregoing buyback right, and as such, Germany is no longer considered part of the licensed territories.

In consideration for entering into the WPD Agreement, WPD agreed that it must use Commercially Reasonable Development Efforts to develop and commercialize
products in the licensed territories. For purposes of the WPD Agreement, the term “Commercially Reasonable Development Efforts” means the expenditure by or on behalf of
WPD  or  any  of  its  affiliates  of  at  least:  (i)  $2.5  million  during  the  first two  years  of  the  agreement  on  the  research,  development  and  commercialization  of  products  in  the
licensed territories; and (ii) $1.0 million annually for the two years thereafter on the research and development of products in the licensed territories. This license is subject to the
terms in the prior agreements entered into by the Company with Dermin and MDA. WPD is actively seeking Polish government grants for research involving licensed drug
candidates. Prior to approval of the WPD Agreement, the Company's board of directors received a fairness opinion from Roth Capital Partners, LLC that stated that it was their
opinion that the consideration the Company will receive from WPD pursuant to the WPD Agreement is fair, from a financial point of view, to the Company.

Animal Life Sciences

In February 2019, the Company sublicensed certain intellectual property rights, including rights to Annamycin, its WP1122 portfolio, and its WP1066 portfolio in the
field  of  non-human  animals  to ALI  (the  “ALI Agreement”). ALI  is  affiliated  with  Dr.  Waldemar  Priebe,  one  of  its  founders  and  its  largest  shareholder.  Under  the ALI
Agreement, the Company granted ALI a worldwide royalty-bearing, exclusive license to research, develop, manufacture, have manufactured, use, import, offer to sell and/or sell
products in the field of non-human animals under the licensed intellectual property. This license is subject to the terms in the prior agreements entered into by the Company and
MDA. Under the ALI Agreement, the Company has the right to name an observer to ALI's board of directors. In August 2019, the Company named its Chairman and CEO
Walter V. Klemp to that position. Since ALI and WPD are beginning the process to develop and commercialize products using the sublicensed intellectual property rights, the
Company is currently unable to predict whether ALI and WPD will be successful in developing such products or when the Company may recognize royalty revenues related to
such products.

Employment Agreements

 The Company has agreements with certain executive and other employees to provide benefits in the event of termination. The base salary and certain other benefits would

aggregate approximately $0.9 million using the rate of compensation in effect at December 31, 2019.

9. Subsequent Events

In addition to the subsequent events discussed elsewhere in these notes, see below for a discussion of our subsequent events occurring after December 31, 2019.

Offering

In  February  2020,  the  Company  entered  into  subscription  agreements  with  certain  institutional  investors  for  the  sale  by  the  Company  of  up  to 7,500,000  shares  of
common stock and warrants to purchase 5,625,000 shares of common stock at $0.80 per share and related warrant. The warrants will be exercisable six months from the date of
issuance at a price of $1.05 per

85

 
share  and  will  expire five years from the date they are first exercisable. The shares of common stock are being offered together with the warrants, but the securities will be
issued  separately  and  will  be  separately  transferable.  Total  proceeds  of  the  offering  were  approximately  $6.0  million,  prior  to  deducting  the  placement  agent  fees  and  other
estimated offering expenses.

Pandemic

In March 2020, the World Health Organization declared the outbreak of a novel Coronavirus (COVID-19) as a pandemic, which continues to spread throughout the
United States. The spread of COVID-19 has caused significant volatility in U.S. and international markets, including Poland, where the Company conducts some of its clinical
trials and Italy, where its drug supply is produced. There has been no interruption of its drug supply, and some Polish clinics where the Company is conducting trials have
limited access on monitoring activities, which for now has not slowed the progress of its trials. This  could  change  at  any  time.  Furthermore,  there  is  significant  uncertainty
around the breadth and duration of business disruptions related to COVID-19, as well as its impact on the US and international economies and, as such, the Company is unable
to determine if it will have a material impact to its operations.

employees,  consultants  or  agents  of  Consultant)  under  this  Agreement  are  works  produced  for  hire  and  constitute  the  sole  and  exclusive
property  of  the  Company  and  do  not  constitute  any  work  or  work  product,  in  any  way,  covered  by  the  Rules  and  Regulations  contained  in
Section 18 below. In furtherance thereof, the Consultant hereby assigns to the Company all proprietary rights, including, without limitation, to
all patents (and applications therefor), copyrights, trade secrets and trademarks the Consultant might otherwise have, by operation of law or
otherwise, in all inventions, discoveries, creations, properties, works, ideas, information, laboratory notebooks, knowledge and data developed,
reduced  to  practice  or  otherwise  identified  in  connection  with  or  related  to  the  Consultant’s  access  to  Confidential  Information  (as  defined

executors, administrators, transferees and personal representatives, to the fullest extent permitted by law, that the Chief Executive Officer of

execute Supporting Documents and perform all other acts necessary to further evidence such assignment. The Consultant represents that it has
the  authority  to  assign  the  foregoing  rights  to  the  Company  and  that  such  an  assignment  does  not  violate  any  guidelines,  policies,  or  other
requirements imposed on such Consultant by any entity, if applicable.

(b) The Consultant shall not perform any Services during the time that the Consultant is required to devote to any third party.
The Consultant shall not use the funding, resources or facilities of any third party to perform the Services and shall not perform any Services in
any manner that would give any third-party rights to the product of such work.

such information, provided such information was not acquired directly or indirectly from the Company; and

(iv) information, to the extent that it is required to be disclosed by lawful subpoena, court order or written demand of a
federal  or  state  governmental  agency,  of  which  the  Consultant  will  immediately  notify  the  Company  giving  Company  an
opportunity to object and/or seek confidential treatment.

(b)  All  Confidential  Information,  however,  and  wherever  produced,  including,  without  limitation,  Confidential  Information
stored in computer databases or by other electronic means, shall be and remain the sole property of the Company. At any time upon the request
of the Company, or without such request upon termination of the Consultant’s role as a consultant to the Company for whatever reason, such
Consultant  shall  deliver  to  the  Company  (without  retaining  any  electronic  or  physical  copies,  extracts,  or  other  reproductions)  or  destroy
immediately upon the Company’s request all documents and electronic storage devices that contain Confidential Information and that are in
such  Consultant’s  possession  or  subject  to  his  or  its  control,  including,  without  limitation,  any  and  all  records,  drawings,  notebooks,

research  and  development  efforts,  data,  physical  and  chemical  formulations,  formulation  techniques,  compound  characteristics,  product
specifications,  manufacturing  processes  and  operations,  compositions,  analytical  methodology,  safety  and  efficacy  data,  and  testing  data,
patents, patent applications, trademarks, trade secrets, processes, programs, formulas, methods, products, know-how and show-how,  (iv) all
derivatives,

3

improvements, additions, modifications and enhancements to any of the above, (v) information of third parties as to which the Company has an
obligation of confidentiality or a duty to use such information only for certain limited purposes, and (vi) the terms of this Agreement.

(d) During the term of this Agreement, the Consultant agrees to properly protect any proprietary information or trade secrets of
such Consultant’s former or concurrent consultees, employers or companies (or those of its respective employees or principals), if any, and
agrees not to bring onto the premises of the Company any unpublished documents or any property belonging to such persons or companies
unless consented to in writing (which consent shall be provided to the Company in advance) by those persons or companies. The  Consultant
further recognizes that the Company has received and, in the future, will receive from third parties their confidential or proprietary information
subject to a duty on the Company’s part to maintain the confidentiality of such information and, in some cases, to use it only for certain limited
purposes. The  Consultant  agrees,  both  during  the  term  of  the  Consultant’s  engagement  and  thereafter,  to  hold  all  such  confidential  or
proprietary information in the strictest confidence and not to disclose it to any person, firm or corporation (except in a manner that is consistent
with the Company’s agreement with the third party) or use it for the benefit of anyone other than the Company or such third party (consistent
with the Company’s agreement with the third party).

5.

Company  Policies.  If,  at  any  time,  the  Consultant  is  required  to  work  at  any  of  the  Company’s  premises  or  use  any  of  its
equipment, the Consultant will comply with all relevant health, safety and security regulations and related instructions issued by the Company.
By executing this Agreement, the Consultant acknowledges that it has received and reviewed the Company’s Code of Business Conduct and
Ethics and the Company’s Anti-Bribery Compliance Policy, and that it agrees to comply with the provisions and restrictions set forth therein.

6.

possession or under such Consultant’s direct or indirect control.

(c) The provisions of Sections 3, 4, and 6 shall survive the expiration or earlier termination of this Agreement.

7.

Conflicts of Interest. The Consultant hereby represents and warrants that he or it is not a party to any existing agreement that
will be breached by such Consultant’s performance of the Services or that conflict with the terms of this Agreement.  During the Term, if the
Consultant intends to enter into any activity, employment, or business arrangement that is in conflict with the Company’s interests in the cancer
drug  area  or  such  Consultant’s  obligations  under  this  Agreement,  then  such  Consultant  agrees  to  notify  the  Company  thereof  prior  to
implementation and the Company shall have the right either (a) to approve such Consultant’s

4

plans thereby waiving any conflict or (b) to terminate this Agreement immediately upon written notice to such Consultant.

8.

Waiver. A party’s failure to enforce, at any time or for any period of time, any provision of this Agreement, or to exercise any
right  or  remedy,  does  not  constitute  a  waiver  of  such  provision,  right  or  remedy,  or  prevent  such  party  thereafter  from  enforcing  any  or  all
provisions and exercising any or all other rights and remedies. The exercise of any right or remedy does not constitute an election or prevent
the exercise of any or all rights or remedies, all rights and remedies being cumulative.

9.
