The following discussion and analysis of financial condition and results of
operations is provided to enhance the understanding of, and should be read in
conjunction with Part I, Item I, "Business" and Item 8, 'Financial Statements
and Supplementary Data." For information on risks and uncertainties related to
our business that may make past performance not indicative of future results or
cause actual results to differ materially from any forward looking statements,

'Risk Factors."

Overview

We are a clinical-stage biopharmaceutical company focused on developing and
commercializing novel cancer therapeutics that reactivate the mutant p53 tumor
suppressor protein. p53 is the protein expressed from the TP53 gene, the most
commonly mutated gene in cancer. We believe that mutant p53 is an attractive
therapeutic target due to the high incidence of p53 mutations across a range of
cancer types and its involvement in key cellular activities such as apoptosis.
Cancer patients with mutant p53 face a significantly inferior prognosis even
when treated with the current standard of care, and a large unmet need for these
patients remains.

Our lead product candidate, APR-246, or eprenetapopt, is a small molecule p53
reactivator that is in clinical development for hematologic malignancies,
including myelodysplastic syndromes, or MDS, and acute myeloid leukemia, or AML.
Eprenetapopt has received orphan drug, fast track and breakthrough therapy
designations from the FDA for MDS, fast track designation from the FDA for AML
and orphan drug designation from the European Commission for MDS and AML, and we
believe eprenetapopt will be a first-in-class therapy if approved by applicable
regulators. In June 2020, we completed full enrollment of 154 patients in a
pivotal Phase 3 trial of eprenetapopt with azacitidine for frontline treatment
of TP53 mutant MDS. The pivotal Phase 3 trial is supported by data from two
Phase 1b/2 investigator initiated trials, one in the U.S. and one in France,
testing eprenetapopt with azacitidine as frontline treatment in TP53 mutant MDS
and AML patients. The complete data sets from the U.S. and French Phase 1b/2
trials were published in The Journal of Clinical Oncology in January 2021 and
February 2021, respectively. In December 2020, we announced that our pivotal
Phase 3 trial failed to meet its predefined primary endpoint of complete
remission (CR) rate. Analysis of the primary endpoint at this data cut
demonstrated a higher CR rate in the experimental arm receiving eprenetapopt
with azacitidine versus the control arm receiving azacitidine alone, but did not
reach statistical significance.

We are conducting, supporting and planning multiple clinical trials of eprenetapopt:

Phase 2 MDS/AML Post-Transplant Trial -- We have completed enrollment of 33

patients in a single-arm, open-label Phase 2 trial evaluating eprenetapopt with

? azacitidine as post-transplant maintenance therapy in TP53 mutant MDS and AML

patients who have received an allogeneic stem cell transplant. We anticipate

initial results from the primary endpoint of relapse-free survival at 12 months

in the second quarter of 2021.

Phase 1/2 AML Trial -- We are currently enrolling a Phase 1/2 clinical trial

evaluating the safety, tolerability, and preliminary efficacy of eprenetapopt

therapy in TP53 mutant AML patients. The lead-in portion of the trial evaluated

the tolerability of eprenetapopt with venetoclax, with or without azacitidine,

and no dose-limiting toxicities were observed in 12 patients receiving either

regimen. Based on these results, we have expanded the trial to treat 33

? additional frontline TP53 mutant AML patients with the combination of

eprenetapopt, venetoclax and azacitidine. In the 19 frontline AML patients who

are evaluable for efficacy with the triplet regimen, we have observed a 63% CR

+ CRi composite response rate and a 31% CR rate. We anticipate completion of

enrollment in the triplet regimen expansion cohort during the second quarter of

2021 and availability of preliminary response rate data from the cohort also in

the second quarter of 2021.

Phase 1 NHL Trial -- We are currently enrolling a Phase 1 clinical trial in

relapsed/refractory TP53 mutant chronic lymphoid leukemia (CLL) assessing

eprenetapopt with venetoclax and rituximab and eprenetapopt with ibrutinib in

? order to further assess eprenetapopt in hematological malignancies. The first

patient was enrolled in the first quarter of 2021. We are also planning to


   evaluate the combination of eprenetapopt with venetoclax in relapsed/refractory
   mantle cell lymphoma.

Phase 1/2 Solid Tumor Trial - We are currently enrolling a Phase 1/2 clinical

trial in relapsed/refractory gastric, bladder and non-small cell lung cancers

assessing eprenetapopt with anti-PD-1 therapy. The dose-escalation phase of the

? trial enrolled 6 patients with advanced solid tumors and no dose-limiting

toxicities were observed. Based on these results, we are enrolling expansion

cohorts for patients with advanced gastric, bladder and non-small cell lung

cancers and have currently enrolled 8 patients across these expansion arms.




Our second product candidate, APR-548, is a next generation p53 reactivator that
is being developed in an oral dosage form. We have planned a Phase 1
dose-escalation clinical trial evaluating safety, tolerability and preliminary
efficacy of APR-548 with azacitidine in frontline and relapsed/refractory MDS
patients. We anticipate the first patient to be enrolled early in the second
quarter of 2021.



Aprea Therapeutics AB, or Aprea AB, was originally incorporated in 2002 and
commenced principal operations in 2006. We incorporated Aprea Therapeutics, Inc.
(the "Company") in May 2019. In September 2019 we completed a corporate
reorganization and, as a result, all of the issued and outstanding stock of
Aprea AB was exchanged for common stock, preferred stock or options, as
applicable, of the Company. As a result of such transactions, Aprea AB became a
wholly-owned subsidiary of the Company.

We have devoted substantially all of our resources to developing our product
candidates, including eprenetapopt, building our intellectual property
portfolio, business planning, raising capital and providing general and
administrative support for these operations. To date, we have financed our
operations through private placements of preferred stock and the net proceeds
received from the initial public offering (IPO) of our common stock. Through
December 31, 2020, we had received net proceeds of approximately $223.9 million
from our sales of preferred and common stock.

Since our inception, we have incurred significant losses on an aggregate basis.
Our ability to generate product revenue sufficient to achieve profitability will
depend on the successful development and eventual commercialization of one or
more of our product candidates. Our net losses were $53.5 million, $28.1 million
and $15.5 million for the years ended December 31, 2020, 2019 and 2018,
respectively. As of December 31, 2020, we had an accumulated deficit of $144.0
million. These losses have resulted primarily from costs incurred in connection
with research and development activities, patent investment, and general and
administrative costs associated with our operations. We expect to continue to
incur significant expenses and increasing operating losses for at least the next
several years.

We anticipate that our expenses will increase substantially if and as we:

? conduct our current and future clinical trials and additional preclinical

research of eprenetapopt;

? initiate and continue research and preclinical and clinical development of our

other product candidates;

? seek to identify and develop additional product candidates;

? seek marketing approvals for any of our product candidates that successfully

complete clinical trials, if any;

? establish a sales, marketing, manufacturing and distribution infrastructure to

commercialize any products for which we may obtain marketing approval;

? require the manufacture of larger quantities of our product candidates for

clinical development and potentially commercialization;

? maintain, expand, protect and enforce our intellectual property portfolio;

? acquire or in-license other drugs and technologies;

? defend against any claims of infringement, misappropriation or other violation


  of third-party intellectual property;


                                      119

--------------------------------------------------------------------------------

Table of Contents

? hire and retain additional clinical, quality control and scientific personnel;

and

add operational, financial and management information systems and personnel, ? including personnel to support our drug development, any future

commercialization efforts and our transition to a public company.




Furthermore, if we obtain marketing approval for any of our product candidates,
we expect to incur significant commercialization expenses related to product
manufacturing, marketing, sales and distribution.

As a result, we will need additional financing to support our continuing
operations. Until such time as we can generate significant revenue from product
sales, if ever, we expect to finance our operations through a combination of
public or private equity or debt financings or other sources, which may include
collaborations with third parties. We may be unable to raise additional funds or
enter into other agreements or arrangements when needed on favorable terms, or
at all. If we fail to raise capital or enter into such agreements as and when
needed, we may have to significantly delay, scale back or discontinue the
development or commercialization of one or more of our product candidates.

Because of the numerous risks and uncertainties associated with product
development, we are unable to predict the timing or amount of increased expenses
or when or if we will be able to achieve or maintain profitability. Even if we
are able to generate revenue from product sales, we may not become profitable.
If we fail to become profitable or are unable to sustain profitability on a
continuing basis, then we may be unable to continue our operations at planned
levels and be forced to reduce or terminate our operations.

As of December 31, 2020, we had cash and cash equivalents of $89.0 million. We
believe that our existing cash and cash equivalents, will enable us to fund our
operating expenses and capital expenditure requirements into 2023. We have based
this estimate on assumptions that may prove to be wrong, and we could exhaust
our available capital resources sooner than we expect. See "-Liquidity and
Capital Resources."

The COVID-19 pandemic



The novel coronavirus outbreak (COVID-19) has been declared a "Public Health
Emergency of International Concern" by the World Health Organization. COVID-19
has spread to the countries in which we, our suppliers, and our other business
partners conduct business. Governments in affected regions have implemented, and
may continue to implement or re-implement, safety precautions, including
quarantines, travel restrictions, business closures, cancellations of public
gatherings, and other measures they deem necessary. Like many other
organizations and individuals, the Company and our employees are taking
additional steps to avoid or reduce infection, including limiting travel and
implementing remote work arrangements. We will continue to actively monitor the
situation and may take further actions that could alter our business operations
as may be required by national, state, or local authorities, or that we
determine are in the best interests of our employees and stockholders.



As a result of the COVID 19 pandemic and policy responses to it, in April and
May 2020 we did initially observe a decrease in both patient screening and
patient enrollment in certain of our ongoing clinical trials. Patient screening
and the number of patients eligible for enrollment in our clinical trials has
returned to expected levels. Together with our investigators and clinical sites,
we continue to assess the impact of the coronavirus pandemic on enrollment and
the ability to maintain patients enrolled in our clinical trials and the
corresponding impact on the timing of the completion of our ongoing clinical
trials.



We have assessed both capacity and the current clinical supply chain associated
with the production of eprenetapopt and have observed no disruptions to date in
our clinical supply chain and our ability to provide supply for our on-going
clinical trials. We will continue to monitor and assess the potential impact of
the COVID-19 pandemic on our clinical trial supply chain.



There are many uncertainties regarding the COVID-19 pandemic, and we are closely
monitoring the impact of the pandemic on all aspects of our business, including
how it will impact our clinical trials, employees, suppliers, vendors and
business partners. While the pandemic did not materially affect our financial
results and business operations for the year ended December 31, 2020, we are
unable to predict the impact that COVID-19 will have on our financial position

                                      120

--------------------------------------------------------------------------------

and operating results at this time due to numerous uncertainties such as the
duration and spread of the outbreak. We will continue to assess the evolving
impact of the COVID-19 pandemic and will make adjustments to our operations if
necessary.


Components of our results of operations

Revenue



We have not generated any revenue from product sales and do not expect to
generate any revenue from the sale of products in the near future. If our
development efforts for eprenetapopt or other product candidates that we may
develop in the future are successful and result in marketing approval or
collaboration or license agreements with third parties, we may generate revenue
in the future from a combination of product sales or payments from collaboration
or license agreements that we may enter into with third parties.

Operating expenses

Our expenses since inception have consisted solely of research and development costs and general and administrative costs.

Research and development expenses



Research and development expenses consist primarily of costs incurred for our
research activities, including our discovery efforts, and the development of our
product candidates, and include:

expenses incurred under agreements with third parties, including contract

research organizations, or CROs, that conduct research, preclinical activities ? and clinical trials on our behalf as well as contract manufacturing

organizations, or CMOs, that manufacture our product candidates for use in our

preclinical and clinical trials;

? salaries, benefits and other related costs, including stock-based compensation

expense, for personnel engaged in research and development functions;

? costs of outside consultants, including their fees, stock-based compensation

and related travel expenses;

? costs of laboratory supplies and acquiring, developing and manufacturing

preclinical study and clinical trial materials;

? expenses related to compliance with regulatory requirements; and

facility-related expenses, which include direct depreciation costs and ? allocated expenses for rent and maintenance of facilities and other operating

costs.




We expense research and development costs as incurred. We recognize costs for
certain development activities, such as clinical trials, based on an evaluation
of the progress to completion of specific tasks using data such as patient
enrollment, clinical site activations, or information provided to us by our
vendors and our clinical investigative sites. Payments for these activities are
based on the terms of the individual agreements, which may differ from the
pattern of costs incurred, and are reflected in our financial statements as
prepaid or accrued research and development expenses.

We typically use our employee and infrastructure resources across our
development programs. We track outsourced development costs and payments made to
our research partners by product candidate or development program, but we do not
allocate personnel costs or other internal costs to specific development
programs or product candidates.

Research and development activities are central to our business model. Product
candidates in later stages of clinical development generally have higher
development costs than those in earlier stages of clinical development,
primarily due to the increased size and duration of later-stage clinical trials.
We expect that our research and development expenses

                                      121

--------------------------------------------------------------------------------

Table of Contents



will continue to increase for the foreseeable future as we initiate additional
clinical trials of eprenetapopt, pursue later stages of clinical development of
eprenetapopt, initiate clinical trials for product candidates other than
eprenetapopt and continue to discover and develop additional product candidates.

We cannot determine with certainty the duration and costs of the current or
future clinical trials of our product candidates or if, when, or to what extent
we will generate revenue from the commercialization and sale of any our product
candidates for which we obtain marketing approval. We may never succeed in
obtaining marketing approval for any of our product candidates. The duration,
costs and timing of clinical trials and development of our product candidates
will depend on a variety of factors, including:

the scope, rate of progress, expense and results of our ongoing clinical trials ? of eprenetapopt, as well as of any future clinical trials of eprenetapopt or

other product candidates and other research and development activities that we

may conduct;

? uncertainties in clinical trial design and patient enrollment rates;

? significant and changing government regulation and regulatory guidance;

? the timing and receipt of, and any limitations imposed by regulatory bodies on,

any marketing approvals; and

? the expense of filing, prosecuting, defending and enforcing any patent claims

and other intellectual property rights.




A change in the outcome of any of these variables with respect to the
development of a product candidate could mean a significant change in the costs
and timing associated with the development of that product candidate. For
example, if the U.S. Food and Drug Administration, or FDA, or another regulatory
authority were to require us to conduct clinical trials beyond those that we
anticipate will be required for the completion of clinical development of a
product candidate, or if we experience significant trial delays due to patient
enrollment or other reasons, we would be required to expend significant
additional financial resources and time on the completion of clinical
development.

We are currently conducting multiple clinical trials of eprenetapopt: a Phase 3
trial in the United States for the treatment of TP53 mutant MDS with
azacitidine, Phase 1b/2 trials in the United States and France for the treatment
of TP53 mutant MDS and AML with azacitidine, a Phase 2 trial of post-transplant
maintenance therapy with azacitidine in TP53 mutant MDS and AML, a Phase 1b/2
trial for the treatment of TP53 mutant AML with venetoclax and azacitidine and a
Phase 1/2 solid tumor trial assessing eprenetapopt with anti-PD-1 therapy and a
Phase 1/2 trial for the treatment of TP53 mutant relapsed/refractory CLL with
venetoclax and rituximab or with ibrutinib. We are currently conducting a Phase
1 trial of APR-548 with azacitidine in TP53 mutant frontline and
relapsed/refractory MDS. At this time, we cannot reasonably estimate the cost
for initiating and completing other clinical trials or preclinical studies of
eprenetapopt or other product candidates, as it will be highly dependent on the
clinical data from ongoing clinical trials as well as any target disease
subpopulations chosen for further evaluation.

General and administrative expenses



General and administrative expenses consist primarily of salaries and other
related costs, including stock-based compensation, for personnel in our
executive, finance, corporate and business development and administrative
functions. General and administrative expenses also include legal fees relating
to patent and corporate matters; professional fees for accounting, auditing, tax
and consulting services; insurance costs; travel expenses; and facility-related
expenses, which include direct depreciation costs and allocated expenses for
rent and maintenance of facilities and other operating costs.

We expect that our general and administrative expenses will increase in the
future as we increase our headcount to support personnel in research and
development and to support our operations generally as we increase our research
and development activities and activities related to the potential
commercialization of our product candidates. We also expect to incur increased
expenses associated with being a public company, including costs of accounting,
audit, legal, regulatory and tax-related services associated with maintaining
compliance with exchange listing and SEC requirements; director and officer
insurance costs; and investor and public relations costs.

                                      122

Other income and expense

Interest income and expense

Interest income consists of income earned on our cash and cash equivalents.
Interest expense consists of bank charges and fees incurred on our cash and cash
equivalents. Our interest income initially increased as our cash and cash
equivalents were higher due to the cash proceeds received from our IPO. Such
interest income is subsequently decreasing as our cash balance decreases as we
continue to fund operations.

Foreign currency gain

Our consolidated financial statements are presented in U.S. dollars, which is
our reporting currency. The financial position and results of operations of our
subsidiaries Aprea AB and Aprea Personal AB are measured using the foreign
subsidiaries' local currency as the functional currency. Aprea AB cash accounts
holding U.S. dollars are remeasured based upon the exchange rate at the date of
remeasurement with the resulting gain or loss included in the consolidated
statement of operations and comprehensive loss. Expenses of such subsidiaries
have been translated into U.S. dollars at average exchange rates prevailing
during the period. Assets and liabilities have been translated at the rates of
exchange on the consolidated balance sheet date. The resulting translation gain
and loss adjustments are recorded directly as a separate component of
stockholders' equity and as other comprehensive loss on the consolidated
statement of operations and comprehensive loss.

Income taxes



We have not recorded any U.S. federal, state or foreign income tax expense or
benefits for the net losses we have incurred in any year, due to our uncertainty
of realizing a benefit from those items. We have provided a valuation allowance
for the full amount of the net deferred tax assets as, based on all available
evidence, it is considered more likely than not that all the recorded deferred
tax assets will not be realized in a future period. At December 31, 2020, we had
$118.0 million, $28.9 million, and $28.6 million of foreign, federal and state
net operating loss carryforwards, respectively, that expire at various dates
through 2036. Certain of these foreign, federal and state net operating loss
carryforwards may be subject to Internal Revenue Code Section 382 or similar
provisions, which impose limitations on their utilization amounts.

Critical accounting policies and use of estimates



Our management's discussion and analysis of financial condition and results of
operations is based on our financial statements, which have been prepared in
accordance with generally accepted accounting principles in the United States.
The preparation of our financial statements and related disclosures requires us
to make estimates and assumptions that affect the reported amounts of assets and
liabilities, costs and expenses in our financial statements. We base our
estimates on historical experience, known trends and events and various other
factors that we believe are reasonable under the circumstances, the results of
which form the basis for making judgments about the carrying values of assets
and liabilities that are not readily apparent from other sources. We evaluate
our estimates and assumptions on an ongoing basis. Our actual results may differ
from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our financial statements, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation of our financial statements.

Accrued research and development expenses



As part of the process of preparing our financial statements, we are required to
estimate our accrued research and development expenses at each balance sheet.
This process involves reviewing open contract and purchase orders, communicating
with our personnel to identify services that have been performed on our behalf
and estimating the level of service performed and the associated costs incurred
for the services when we have not yet been invoiced or otherwise notified of the
actual costs. The majority of our service providers invoice us in arrears for
services performed, on a pre-

                                      123

--------------------------------------------------------------------------------

Table of Contents



determined schedule or when contractual milestones are met; however, some
require advanced payments. We make estimates of our accrued expenses as of each
balance sheet date in our financial statements based on facts and circumstances
known to us at that time. Examples of estimated accrued research and development
expenses include fees paid to:

? CROs in connection with performing research activities on our behalf and

conducting preclinical studies and clinical trials on our behalf;

? investigative sites or other service providers in connection with clinical

trials;

? vendors in connection with preclinical and clinical development activities; and

? vendors related to product manufacturing and development and distribution of

preclinical and clinical supplies.




We base our expenses related to preclinical studies and clinical trials on our
estimates of the services received and efforts expended pursuant to quotes and
contracts with multiple CROs that conduct and manage preclinical studies and
clinical trials on our behalf. The financial terms of these agreements are
subject to negotiation, vary from contract to contract and may result in uneven
payment flows. There may be instances in which payments made to our vendors will
exceed the level of services provided and result in a prepayment of the expense.
Payments under some of these contracts depend on factors such as the successful
enrollment of patients and the completion of clinical trial milestones. In
accruing fees, we estimate the time period over which services will be
performed, enrollment of patients, number of sites activated and the level of
effort to be expended in each period. If the actual timing of the performance of
services or the level of effort varies from our estimate, we adjust the accrual
or amount of prepaid expense accordingly. 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 relative to the
actual status and timing of services performed may vary and may result in us
reporting amounts that are too high or too low in any particular period. To
date, we have not made any material adjustments to our prior estimates of
accrued research and development expenses.

Stock-based compensation



We measure stock options and other stock-based awards granted to employees and
directors based on their fair value on the date of the grant and recognize
compensation expense of those awards, over the requisite service period, which
is generally the vesting period of the respective award. We apply the
straight-line method of expense recognition to all awards with only
service-based vesting conditions and apply the graded-vesting method to all
awards with performance-based vesting conditions or to awards with both
service-based and performance-based vesting conditions.

For stock-based awards granted to non-employees, compensation expense is
recognized over the period during which services are rendered by such
non-employees until completed in accordance with the FASB issued
ASU No. 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to
Nonemployee Share-Based Payment Accounting. The new standard largely aligns the
accounting for share-based payment awards issued to employees and nonemployees
by expanding the scope of ASC 718 to apply to nonemployee share-based
transactions, as long as the transaction is not effectively a form of financing.

We estimate the fair value of each stock option grant on the date of grant using
the Black-Scholes option-pricing model, which uses as inputs the fair value of
our common stock and assumptions we make for the volatility of our common stock,
the expected term of our stock options, the risk-free interest rate for a period
that approximates the expected term of our stock options and our expected
dividend yield.

Determination of fair value of common stock



As a privately held company (through October 2, 2019), there had been no public
market for our common stock, the estimated fair value of our common stock had
been determined by our board of directors as of the date of each option grant,
with input from management, considering our most recently available third-party
valuations of common stock and our board of directors' assessment of additional
objective and subjective factors that it believed were relevant and which

                                      124

--------------------------------------------------------------------------------

Table of Contents



may have changed from the date of the most recent valuation through the date of
the grant. These third-party valuations were performed in accordance with the
guidance outlined in the American Institute of Certified Public Accountants'
Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity
Securities Issued as Compensation. Our common stock valuations were prepared
using a hybrid method, which used market approaches to estimate our enterprise
value. The hybrid method is a probability-weighed expected return method, or
PWERM, where the equity value in one or more scenarios is calculated using an
option-pricing method, or OPM. The OPM treats common stock and preferred stock
as call options on the total equity value of a company, with exercise prices
based on the value thresholds at which the allocation among the various holders
of a company's securities changes. Under this method, the common stock has value
only if the funds available for distribution to stockholders exceeded the value
of the preferred stock liquidation preference at the time of the liquidity
event, such as a strategic sale or a merger. The PWERM is a scenario-based
methodology that estimates the fair value of common stock based upon an analysis
of future values for the company, assuming various outcomes. The common stock
value is based on the probability-weighted present value of expected future
investment returns considering each of the possible outcomes available as well
as the rights of each class of stock. The future value of the common stock under
each outcome is discounted back to the valuation date at an appropriate
risk-adjusted discount rate and probability weighted to arrive at an indication
of value for the common stock. These third-party valuations were performed at
various dates, which resulted in valuations of our common stock of $0.92 per
share as of May 31, 2016, $1.01 per share as of October 2, 2017, $3.18 per share
as of December 31, 2018 and $10.95 per share as of July 15, 2019.

In addition to considering the results of these third-party valuations, our board of directors considered various objective and subjective factors to determine the fair value of our common stock as of each grant date, including:

the prices at which we sold shares of preferred stock and the superior rights ? and preferences of the preferred stock relative to our common stock at the time

of each grant;

? the progress of our research and development programs, including the status and

results of preclinical studies and clinical trials for our product candidates;

? our stage of development and commercialization and our business strategy;

? external market conditions affecting the biopharmaceutical industry and trends

within the biopharmaceutical industry;

? our financial position, including cash on hand, and our historical and

forecasted performance and operating results;

? the lack of an active public market for our common stock and our preferred

stock;

the likelihood of achieving a liquidity event, such as an initial public ? offering, or IPO, or sale of our company in light of prevailing market

conditions; and

? the analysis of IPOs and the market performance of similar companies in the

biopharmaceutical industry.

The assumptions underlying these valuations represented management's best estimate, which involved inherent uncertainties and the application of management's judgment. As a result, if we had used significantly different assumptions or estimates, the fair value of our common stock and our stock-based compensation expense could have been materially different.

Emerging growth company and smaller reporting company status



We are an emerging growth company (EGC), as defined in the JOBS Act. Under this
act, emerging growth companies are permitted to delay adopting new or revised
accounting standards applicable to public companies until those standards would
otherwise apply to private companies. We have irrevocably elected not to avail
ourselves of this exemption from

                                      125

--------------------------------------------------------------------------------

Table of Contents

new or revised accounting standards and, therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.



We may remain classified as an EGC until the end of the fiscal year in which the
fifth anniversary of our IPO occurs, although if the market value of our common
stock that is held by non-affiliates exceeds $700 million as of any June 30
before that time or if we have annual gross revenues of $1.07 billion or more in
any fiscal year, we would cease to be an EGC as of December 31 of the applicable
year. We also would cease to be an EGC if we issue more than $1 billion of
non-convertible debt over a three-year period.

We are also a "smaller reporting company," as such term is defined in Rule 12b-2
of the Exchange Act, meaning that the market value of our common stock held by
non-affiliates is less than $700 million and our annual revenue is less than
$100 million during the most recently completed fiscal year. We may continue to
be a smaller reporting company if either (i) the market value of our common
stock held by non-affiliates is less than $250 million or (ii) our annual
revenue is less than $100 million during the most recently completed fiscal year
and the market value of our common stock held by non-affiliates is less than
$700 million. If we are a smaller reporting company at the time we cease to be
an emerging growth company, we may continue to rely on exemptions from certain
disclosure requirements that are available to smaller reporting companies.
Specifically, as a smaller reporting company we may choose to present only the
two most recent fiscal years of audited financial statements in our Annual
Report on Form 10-K and, similar to emerging growth companies, smaller reporting
companies have reduced disclosure obligations regarding executive compensation.

Research and development expenses for the year ended December 31, 2020 were
$37.9 million, compared to $21.0 million for the year ended December 31, 2019.
The increase of $16.9 million was primarily due to the continued development of
our lead product candidate eprenetapopt as follows:

an increase of $6.1 million related to our pivotal Phase 3 clinical trial of

eprenetapopt with azacitidine for frontline treatment of TP53 mutant MDS which

? completed enrollment in Q2 2020. The $6.1 million increase included $3.5

million related to the development of an in vitro companion diagnostic test for

eprenetapopt. The agreement for the development of an in vitro diagnostic test


   was terminated in December 2020;

? an increase of $2.1 million in regulatory expenses primarily related to the

preparation of a New Drug Application (NDA) for eprenetapopt.

? an increase of $1.0 million in pre-clinical expenses associated with increased

activity.

General and administrative expenses



General and administrative expenses for the year ended December 31, 2020 were
$14.9 million, compared to $8.6 million for the year ended December 31, 2019.
The increase of $6.3 million was primarily related to increases of $2.5 million
in insurance expense, $2.0 million in commercial development expense, $1.5
million in non-cash stock-based compensation expense and $0.9 million in
personnel expense offset, in part, by a decrease of $0.7 million in legal and
consulting fees. The increase in non-cash stock-based compensation expense was
primarily related to stock option grants made in October 2019 in connection with
our IPO and in March 2020 in connection with the Company's annual compensation
review. The increase in insurance expense was primarily related to costs
associated with being a public company and commercial development expense
relates to the initiation of certain pre-commercialization activities, such as
market research and brand building. The decrease in legal and consulting fees is
related to costs incurred in connection with preparations for our IPO which was
completed in October 2019. No such costs were incurred in 2020.

Other income and expense



Foreign currency loss for the year ended December 31, 2020 was $0.9 million
compared to a foreign currency gain of $1.3 million for the year ended December
31, 2019. The decrease of $2.4 million was primarily due to a weakening of the
U.S. dollar against the Swedish Krona during the year ended December 31, 2020.
Interest income for the year ended December 31, 2020 consisted primarily of
interest earned on our cash and cash equivalents.

Research and development expenses






                                                       Years ended December 31,
                                                         2019            2018          Change

Total research and development expenses              $ 20,950,672    $ 14,194,732    $ 6,755,940




Research and development expenses for the year ended December 31, 2019 were
$21.0 million, compared to $14.2 million for the year ended December 31, 2018.
The increase of $6.8 million was primarily related to the advancement of our
clinical product candidate eprenetapopt. In the first quarter of 2019 we
commenced a pivotal Phase 3 clinical trial of eprenetapopt with azacitidine for
frontline treatment of TP53 mutant MDS which is supported by two ongoing Phase
1b/2 investigator-initiated trials, one in the U.S. and one in France, testing
eprenetapopt with azacitidine as frontline treatment in TP53 mutant MDS and AML
patients.

General and administrative expenses



General and administrative expenses for the year ended December 31, 2019 were
$8.6 million, compared to $2.3 million for the year ended December 31, 2018. The
increase of $6.3 million was primarily related to increases of $3.4 million in
legal and accounting fees, $0.3 million in consulting fees and $1.9 million in
personnel related costs including $1.0 million of non-cash stock-based
compensation. The increase in legal, accounting and consulting fees was
primarily related to costs associated with the corporate reorganization that was
completed in September 2019 as well as the preparation of our financial
statements and overall readiness to become a public company. The increase in
personnel costs was primarily related to increased non-cash stock-based
compensation expense as a result of the addition of a member of senior
management in August 2019.

Other income and expense



Foreign currency gain for the year ended December 31, 2019 was $1.3 million
compared to $0.9 million for the year ended December 31, 2018. The increase of
$0.4 million was primarily due to a strengthening of the U.S. dollar against the
Swedish Krona during the year ended December 31, 2019. Interest income (expense)
for the year ended December 31, 2019 consisted primarily of interest expense
associated with our facility leases and interest income on our cash and cash
equivalents. Interest expense for the year ended December 31, 2018 consisted of
an insignificant amount of banking charges or fees.

Liquidity and capital resources



Since our inception, we have incurred significant losses on an aggregate basis.
We have not yet commercialized any of our product candidates, which are in
various phases of preclinical and clinical development, and we do not expect to
generate revenue from sales of any products for several years, if at all. To
date, we have financed our operations through private placements of our
preferred and common stock and the net proceeds received from the initial public
offering (IPO) of our common stock. Through December 31, 2020, we had received
net proceeds of $223.9 million from our sales of preferred and common stock. As
of December 31, 2020, we had cash and cash equivalents of $89.0 million.

Cash flows



The following table summarizes our sources and uses of cash for each of the
periods presented:




                                                               Years ended December 31,
                                                       2020              2019              2018
Net cash provided by (used in):
Operating activities                              $ (41,802,672)    $ (26,708,707)    $ (15,250,234)
Investing activities                                    (25,709)          (30,901)           (3,702)
Financing activities                                     150,949        92,575,538        56,366,742
Net (decrease) increase in cash and cash
equivalents                                       $ (41,677,432)    $   65,835,930    $   41,112,806




Operating activities

Cash used in operating activities resulted primarily from our net losses
adjusted for non-cash charges and changes in components of working capital. Net
cash used in operating activities was $41.8 million for the year ended December
31, 2020 compared to $26.7 million for the year ended December 31, 2019. The
increase in cash used in operating activities of $15.1 million was primarily
attributable to an increase in our net loss of $25.4 million, resulting from
both increased research and development expenses and increased general and
administrative expenses discussed previously partially offset by an increase in
non-cash stock-based compensation of $3.6 million as well as a net increase in
operating assets and liabilities of $4.4 million.

Net cash used in operating activities was $26.7 million for the year ended
December 31, 2019 compared to $15.3 million for the year ended December 31,
2018. The increase in cash used in operating activities of $11.5 million was
primarily attributable to an increase in our net loss of $12.5 million,
resulting from both increased research and development expenses and increased
general and administrative expenses discussed previously.

Investing activities



Cash used in investing activities for the years ended December 31, 2020, 2019
and 2018 was $25,709, $30,901 and $3,702, respectively. Cash used in investing
activities for these years represented the acquisition and property and
equipment

We expect that investing activities will increase over the next several years.

Financing activities



Net cash provided by financing activities was $0.1 million for the year ended
December 31, 2020 compared to $92.6 million for the year ended December 31,
2019. The decrease in cash provided by financing activities was primarily
attributable to net proceeds of $86.9 million received from our IPO which was
completed in October 2019 and net proceeds of $5.6 million from the issuance of
Series C convertible preferred stock in February 2019. Cash provided by
financing activities for the year ended December 31, 2020 represented proceeds
received from the exercise of stock options.

Net cash provided by financing activities was $92.6 million for the year ended
December 31, 2019 compared to $56.4 million for the year ended December 31,
2018. The increase in cash provided by financing activities of $36.2 million was
primarily attributable to net proceeds of $86.9 million received from our IPO
which was completed in October 2019 and net proceeds of $5.6 million from the
issuance of Series C convertible preferred stock in February 2019.

Funding requirements



We expect our expenses to increase substantially in connection with our ongoing
development activities related to eprenetapopt and other product candidates and
programs which are still in the early stages of clinical development. In

                                      129

--------------------------------------------------------------------------------

Table of Contents



addition, we have incurred and continue to incur additional costs associated
with operating as a public company. We expect that our expenses will increase
substantially if and as we:

? conduct our current and future clinical trials and additional preclinical

research of eprenetapopt;

? decide to continue with the development of an in vitro companion diagnostic

test for eprenetapopt;

? initiate and continue research and preclinical and clinical development of our

other product candidates;

? seek to identify and develop additional product candidates;

? seek marketing approvals for any of our product candidates that successfully

complete clinical trials, if any;

? establish a sales, marketing, manufacturing and distribution infrastructure to

commercialize any products for which we may obtain marketing approval;

? require the manufacture of larger quantities of our product candidates for

clinical development and potentially commercialization;

? maintain, expand, protect and enforce our intellectual property portfolio;

? acquire or in-license other drugs and technologies;

? defend against any claims of infringement, misappropriation or other violation

of third-party intellectual property;

? hire and retain additional clinical, quality control and scientific personnel;

? build out new facilities or expand existing facilities to support our ongoing

development activity;

add operational, financial and management information systems and personnel, ? including personnel to support our drug development, any future

commercialization efforts and our transition to a public company; and

? continue to operate as a public company.




As of December 31, 2020, we had cash and cash equivalents of $89.0 million. We
believe that our existing cash and cash equivalents, will enable us to fund our
operating expenses and capital expenditure requirements into 2023. We have based
this estimate on assumptions that may prove to be wrong, and we could exhaust
our available capital resources sooner than we expect.

Because of the numerous risks and uncertainties associated with the development
of eprenetapopt and other product candidates and programs and because the extent
to which we may enter into collaborations with third parties for development of
our product candidates is unknown, we are unable to estimate the timing and
amounts of increased capital outlays and operating expenses associated with
completing the research and development of our product candidates. Our future
capital requirements will depend on many factors, including:

? the scope, progress, results and costs of our current and future clinical

trials of eprenetapopt for our current targeted indications;

? the scope, progress, results and costs of drug discovery, preclinical research

and clinical trials for eprenetapopt and our other product candidates;

? the number of future product candidates that we pursue and their development


  requirements;


                                      130

--------------------------------------------------------------------------------

Table of Contents

? the costs, timing and outcome of regulatory review of our product candidates;

the extent to which we acquire or invest in businesses, products and ? technologies, including entering into or maintaining licensing or collaboration

arrangements for product candidates on favorable terms, although we currently

have no commitments or agreements to complete any such transactions;

the costs and timing of future commercialization activities, including drug

sales, marketing, manufacturing and distribution, for any of our product ? candidates for which we receive marketing approval, to the extent that such

sales, marketing, manufacturing and distribution are not the responsibility of

any collaborator that we may have at such time;

? the amount of revenue, if any, received from commercial sales of our product

candidates, should any of our product candidates receive marketing approval;

? the impact of COVID-19 on the financial markets in general and on our business

in particular;

the costs of preparing, filing and prosecuting patent applications, ? maintaining, protecting and enforcing our intellectual property rights and

defending intellectual property-related claims;

? our headcount growth and associated costs as we expand our business operations

and our research and development activities; and

? the costs of operating as a public company.




Developing drug products, including conducting preclinical studies and clinical
trials, is a time-consuming, expensive and uncertain process that takes years to
complete, and we may never generate the necessary data or results required to
obtain marketing approval for any product candidates or generate revenue from
the sale of any products for which we may obtain marketing approval. In
addition, our product candidates, if approved, may not achieve commercial
success. Our commercial revenues, if any, will be derived from sales of drugs
that we do not expect to be commercially available for many years, if ever.
Accordingly, we will need to obtain substantial additional funds to achieve our
business objectives.

Adequate additional funds may not be available to us on acceptable terms, or at
all. We do not currently have any committed external source of funds. To the
extent that we raise additional capital through the sale of equity or
convertible debt securities, ownership interests in our securities may be
diluted, and the terms of these securities may include liquidation or other
preferences and anti-dilution protections that could adversely affect the rights
of our common stockholders. Additional debt or preferred equity financing, if
available, may involve agreements that include restrictive covenants that may
limit our ability to take specific actions, such as incurring debt, making
capital expenditures or declaring dividends, which could adversely impact our
ability to conduct our business, and may require the issuance of warrants, which
could potentially dilute existing ownership interest.

If we raise additional funds through collaborations, strategic alliances or
licensing arrangements with third parties, we may have to relinquish valuable
rights to our technology, future revenue streams, research programs, or product
candidates or grant licenses on terms that may not be favorable to us. If we are
unable to raise additional funds through equity or debt financings or
collaborations, strategic alliances or licensing arrangements with third parties
when needed, we may be required to delay, limit, reduce and/or terminate our
product development programs or any future commercialization efforts or grant
rights to develop and market product candidates that we would otherwise prefer
to develop and market ourselves.
