Overview
We are a clinical-stage oncology company developing transformative treatments
designed to halt the progression of life-threatening diseases, including cancer
and fibrosis.
Batiraxcept (formerly AVB-500), is an ultrahigh-affinity, decoy protein that
targets the GAS6-AXL signaling pathway. By capturing serum GAS6, batiraxcept
starves the AXL pathway of its signal, potentially halting the biological
programming that promotes disease progression. AXL receptor signaling plays an
important role in multiple types of malignancies by promoting metastasis, cancer
cell survival, resistance to treatments, and immune suppression.
Our current development program benefits from the availability of a proprietary
serum-based biomarker that has accelerated batiraxcept drug development by
allowing us to select a pharmacologically active dose and may potentially
identify the cancer patients that have the best chance of responding to
batiraxcept.
In our completed Phase 1 clinical trial in healthy volunteers with batiraxcept,
we have demonstrated proof of mechanism for batiraxcept in neutralizing GAS6.
Importantly, batiraxcept had a favorable safety profile preclinically and in the
first in human trial and Phase 1b clinical trial in cancer patients.
In August 2018, the FDA designated as a Fast Track development program the
investigation of batiraxcept for platinum-resistant recurrent ovarian cancer.
In December 2018, we initiated our Phase 1b clinical trial of batiraxcept
combined with standard of care therapies in patients with PROC, for which we
reported results in July 2020.
In April 2020, we entered into a license and collaboration agreement with WuXi,
the objective of which is to identify and develop novel high-affinity bispecific
antibodies against CCN2, also known as CTGF, implicated in cancer and fibrosis
and identified from a similar target discovery screen that identified the
significance of the AXL/GAS6 pathway in cancer. However, in August 2022, the
Company temporarily halted work on the CTGF program with WuXi in an effort to
focus all resources on the clinical programs.
In November 2020, we entered into the 3D Medicines Agreement, whereby we granted
3D Medicines an exclusive license to develop and commercialize products that
contain batiraxcept as the sole drug substance, for the diagnosis, treatment or
prevention of human oncological diseases, in the Territory.
During the fourth quarter of 2020, we initiated our Phase 1b portion of
the Phase 1b/2 trial of batiraxcept in ccRCC and we dosed our first patient in
the trial in March 2021.
During the first quarter 2021, we initiated our registrational Phase 3 trial of
batiraxcept in PROC and we dosed our first patient in the trial in April
2021.This global, randomized, double-blind, placebo-controlled trial is designed
to evaluate efficacy and safety of batiraxcept at a dose of 15 mg/kg in
combination with PAC versus PAC alone.
In May 2021, we announced expansion of batiraxcept development programs into
first line pancreatic ductal adenocarcinoma ("PDAC") with the goal of initiating
the trial by end of 2021. We dosed our first patient in August 2021.
In June 2021, we announced initial safety, pharmacokinetic, and pharmacodynamic
results from the batiraxcept Phase 1b portion of the Phase 1b/2 clinical trial
in ccRCC.
In October 2021, the EMA granted orphan drug designation for batiraxcept for the
treatment of PROC, following a recommendation from the Committee for Orphan
Medicinal Products.
In November 2021, we announced preliminary data from our Phase 1b trial
evaluating batiraxcept in combination with cabozantinib for treatment of ccRCC.
In January 2022, we announced that we had dosed the first patient in the Phase 2
portion of the Phase 1b/2 study of batiraxcept in combination with cabozantinib
for treatment of ccRCC.
In March 2022, we announced updated data and new biomarker data from our Phase
1b trial of batiraxcept in ccRCC.
In May 2022, we provided updated data and information at our Key Opinion Leader
symposium.
In October 2022, we received a $6 million development milestone payment from 3D
Medicines based on the initiation of the global Phase 3 platinum resistant
ovarian cancer ("PROC") clinical trial in the Territory for the development of
batiraxcept.
In November 2022, the FDA designated as a Fast Track development program the
investigation of batiraxcept for treatment of patients with advanced or
metastatic ccRCC who have progressed after 1 or 2 prior lines of systemic
therapy that include both immuno-oncology (IO)-based and vascular endothelial
growth factor tyrosine kinase inhibitor (VEGF-TKI)-based therapies (either in
combination or sequentially).
In January 2023, the Company announced complete enrollment in the global Phase 3
platinum resistant ovarian cancer ("PROC") clinical trial.

Recent Clinical Developments
The Phase 3 Platinum Resistant Ovarian Cancer (PROC) Trial Remains On Track
The registration-directed Phase 3 program of batiraxcept in combination with
paclitaxel in PROC remains on track and enrollment has been completed. We expect
to report topline data from the trial by mid-2023. CMC work remains on track
with the goal of filing a BLA by year-end 2023. The global, randomized,
double-blind, placebo-controlled Phase 3 trial is evaluating efficacy and
tolerability of batiraxcept at a dose of 15 mg/kg in combination with paclitaxel
versus placebo in combination with paclitaxel. The trial has completed
enrollment of over 360 patients with platinum resistant, high-grade serous
ovarian cancer who have received 1-4 prior lines of therapy.
Updated Clear Cell Renal Cell Cancer Data (ccRCC) Continues to Be Encouraging
As of August 8, 2022, 26 previously treated (2L+) patients with ccRCC have been
treated with batiraxcept in the Phase 1b portion of a Phase 1b/2 trial at doses
of 15 mg/kg (n=16) and 20 mg/kg (n=10), plus cabozantinib 60 mg daily. There
were no dose limiting toxicities observed at either dose. The best overall
response rate (ORR, confirmed) in the ITT population was 42%. One of the
objectives of the ongoing Phase 1b/2 ccRCC trial is to evaluate the correlation
of baseline serum soluble AXL (sAXL)/GAS6 (biomarker) with radiographic response
in patients with ccRCC treated with batiraxcept plus cabozantinib. The best ORR
in the biomarker high population was 55%. The 9-month progression-free survival
(PFS) rate was 65% in the ITT population and 72% in the biomarker high
population. We have discussed a registrational path with the US FDA that
includes use of the sAXL/Gas6 ratio as a basis for an accelerated approval.
We expect to report additional data from the Phase 1b portion and preliminary
data from the Phase 2 portion of the ccRCC trial mid-2023.
Expansion of Phase 1b Pancreatic Adenocarcinoma Study
As of September 20, 2022, 18 patients with pancreatic adenocarcinoma ("PDAC")
had been treated with 15 mg/kg (Days 1 & 15) + nab-paclitaxel (125 mg/m2 on Days
1, 8, & 15) and gemcitabine (1000 mg/m2 on Days 1, 8, & 15) and have
pharmacokinetic data. As has been seen for other Phase 1b cancer studies with
batiraxcept, there is a relationship between batiraxcept exposures and clinical
activity such that 5 out of the 9 patients in the PDAC study whose batiraxcept
levels exceeded the minimum efficacious concentration (MEC) of batiraxcept had a
response vs 1 out of 9 patients in the low MEC group. Similarly, the mPFS in the
high MEC group was 5.6 months (95% CI 2.1, not evaluable) vs 2.7 months (95% CI
1.1, 5.4) in the low MEC group. In May 2022, we had reported that batiraxcept in
combination with gemcitabine and nab-paclitaxel was generally well-tolerated
with no unexpected safety signals. Based on these data, we intend to dose an
additional 6-18 patients at higher doses (20mg/kg and potentially 25mg/kg) to
see if higher doses will increase the proportion of patients who will achieve
high MEC of batiraxcept and increase the clinical activity of batiraxcept in
combination with gemcitabine + nab-paclitaxel.
Recent Financial Developments
In January 2022, we entered into an investment agreement (the "Investment
Agreement") with Eshelman Ventures, LLC and, solely for purposes of Article IV
and Article V of the Investment Agreement, Dr. Eshelman, Eshelman Ventures,
agreed to purchase pre-funded warrants of up to 4,545,455 shares of our common
stock, par value $0.0001 per share ("Warrant Shares"), at a price of $2.20 per
share, which was the consolidated closing bid price of our common stock on
Nasdaq on December 31, 2021, for an aggregate purchase price of $10 million.
The closing of the transaction occurred on January 5, 2022. Pursuant to the
terms of the Investment Agreement, we were required to file a registration
statement registering the shares of common stock underlying the pre-funded
warrant. The registration statement was filed on January 5, 2022 and declared
effective by the SEC on January 18, 2022. The pre-funded warrants issued to
Eshelman Ventures, LLC were exercisable upon the approval by our stockholders of
the exercise, which approval was obtained on April 1, 2022, at which time the
pre-funded warrants were exercised in full.
On March 31, 2022, we closed a registered direct offering of our common stock
with a single healthcare-focused institutional investor and Eshelman Ventures,
LLC, pursuant to which we issued 3,185,216 shares of common stock, 1,665,025
pre-funded warrants (the "March Pre-Funded Warrants") and common stock warrants
(the "Common Stock Warrants") to purchase up to 4,850,241 shares of common stock
in a registered direct offering priced at-the-market under Nasdaq rules. The
purchase price per share and accompanying common stock warrant was $2.005 for
the institutional investor and $2.325 for Eshelman Ventures, LLC. The purchase
price per March Pre-Funded Warrant and accompanying Common Stock Warrant was
$2.004 for the institutional investor. The net proceeds from the offering
were $9.3 million, after deducting underwriting discounts, commission and
offering expenses. The Common Stock Warrants issued to the institutional
investor are exercisable immediately, will expire five years from the
exercisable date and will have an exercise price of $1.88 per share. The Common
Stock Warrants issued to Eshelman Ventures, LLC were exercisable upon the
approval by our stockholders of the exercise of previously issued securities,
which approval was obtained on April 1, 2022, will expire five years following
the exercise date and will have an exercise price of $2.20 per share. We could
receive additional gross proceeds of $9.4 million, if the Common Stock Warrants
are fully exercised. The 1,665,025 Pre-Funded Warrants were exercised on June
6, 2022.
On October 27, 2022, we closed a private placement offering with new
biotechnology investors, existing investors, our management and certain of our
directors for the issuance and sale of an aggregate of 45,178,811 shares of our
common stock, or pre-funded warrants in lieu thereof (the "October Pre-Funded
Warrants" and together with the March Pre-Funded Warrants, the "Pre-Funded
Warrants") and warrants (the "October Warrants" and together with the March
Common Warrant, the "Warrants") to purchase up to an aggregate of 45,178,811
shares of common stock or pre-funded warrants (the "Private Placement") priced
at-the-market under Nasdaq rules. The purchase price per share and accompanying
warrant was $0.9199 for all investors who participated in the deal (or $0.9198
per pre-funded warrant and accompanying October Warrant). Fifty percent of the
October Warrants have an exercise price of $0.7949 per share and will expire on
the date that is the later of: (i) 15 months from the date an increase in the
number of authorized shares of common stock is effected, or (ii) one month after
the public announcement of the topline Phase 3 PROC data. The remaining 50% of
the October Warrants have an exercise price of $0.7949 per share and will expire
30 months from the date an increase in the number of authorized shares of common
stock is effected. All of the October Warrants other than the October Pre-funded
warrants are exercisable for exchange of cash from the warrant holder. The net
proceeds were approximately $40 million and will be used to fund our clinical
development programs. Pursuant to the terms of the registration rights
agreements that we entered into, we were required to file a registration
statement registering the shares of common stock issued and the shares of common
stock underlying the October Warrants and October Pre-funded Warrants,
underlying the pre-funded warrant. The registration statement was filed on
November 18, 2022 and declared effective by the SEC on November 28, 2022.
Financial overview
Revenue
To date, we have not generated any revenue from commercial sales of any of our
product candidates. However, for the years ended December 31, 2022 and 2021, we
generated approximately $9.1 million and $7.4 million from the 3D Medicine
Agreement, which represents a portion of initial signing and milestone payments
received from 3D Medicines that is recognized at the time of the receipt and a
portion of the payments that is deferred and recognized over the PROC trial
period.
In the future, we may generate revenue from a variety of sources, including
product sales if we develop products which are approved for sale, license fees,
milestones, research and development and royalty payments in connection with
strategic collaborations or government contracts, or licenses of our
intellectual property.
Research and development expenses
We recognize both internal and external research and development expenses as
incurred. Our external research and development expenses consist primarily of:
• the cost of acquiring and manufacturing clinical trial and other materials,
including expenses incurred under agreements with contract manufacturing
organizations;
• expenses incurred under agreements with contract research organizations,
investigative sites, and consultants that conduct our clinical trials;
• other costs associated with development activities, including additional
studies; and
Internal research and development costs consist primarily of salaries and
related fringe benefit costs for our employees (such as workers' compensation
and health insurance premiums), stock-based compensation charges and travel
costs.
General and administrative expenses
General and administrative expenses consist principally of personnel-related
costs, professional fees for legal, consulting, audit and tax services, rent and
other general operating expenses not included in research and development.
Other income (expense), net
Other income (expense), net is primarily comprised of sublease income for our
1020 Marsh Facility lease, gains and losses on foreign currency transactions
related to third party contracts with foreign-based contract manufacturing
organizations and change in fair value of the warrant liability.

Results of operations
Comparison of the years ended December 31, 2022 and 2021
The following table summarizes our net loss during the periods indicated (in
thousands, except percentages):
Year Ended
December 31, Increase/
2022 2021 (Decrease)
Revenue:
Collaboration revenue $ 9,137 $ 7,442 $ 1,695 23 %
Operating expenses:
Research and development 66,938 37,541 29,397 78 %
General and administrative 13,036 10,550 2,486 24 %
Total operating expenses 79,974 48,091 31,883 66 %
Loss from operations (70,837 ) (40,649 ) 30,188 74 %
Total other income (expense), net (5,485 ) 1,498 (6,983 ) -466 %
Net loss $ (76,322 ) $ (39,151 ) $ 37,171 95 %
Collaboration revenue
Collaboration revenue was approximately $9.1 million and $7.4 million for the
years ended December 31, 2022 and 2021, respectively. The increase in revenue
in 2022 compared to the same period in 2021 was driven primarily by increased
expenditures related to the Phase 3 PROC trial, which drives the recognition of
deferred revenue over the trial period.
Research and development expense
Research and development expense increased by $29.4 million, or 78%, to $66.9
million in 2022 from $37.5 million in 2021. The increase was primarily due to
the continued progress of our clinical programs, including our Phase 3 trial of
batiraxcept in PROC, our Phase 1b/2 trial of batiraxcept in ccRCC, and our Phase
1 trial of batiraxcept in pancreatic cancer. The continued advancement of our
Phase 3 trial of batiraxcept in PROC is the most significant driver to the
increase in expense in 2022 when compared to the same period in 2021. There were
also significant increased CMC manufacturing activities during 2022 in order to
prepare for our BLA filing at the end of 2023.
General and administrative expense
General and administrative expense increased by approximately $2.5 million, or
24%, to approximately $13.0 million in 2022 from approximately $10.6 million for
the same period in 2021. The increase was primarily driven by higher salary
expense, higher stock-based compensation expense, higher severance expense, and
increased consulting fees.
Total other income (expense), net
Total other income (expense), net fluctuated by approximately $7.0 million, to
approximately $5.5 million of total other expense, net in 2022 from
approximately $1.5 million of total other income, net in 2021. The
change relates to sublease income received from our subtenant for a full year in
2022, compared to only a part of the year in 2021, offset by an increase in the
fair value of our warrant liability totaling approximately $9.0 million for
2022.

Liquidity and Capital Resources
Since our inception and through December 31, 2022, we have financed our
operations through private placements of our equity securities, public offerings
of our equity securities, debt financing, CPRIT grant proceeds, sales of common
stock through our at-the-market facility as well as payments received from
license agreements. As of December 31, 2022, we had an accumulated deficit of
approximately $616.1 million, primarily as a result of research and development
and general and administrative expenses, and working capital of $35.9 million.
As of December 31, 2022, we had cash and cash equivalents of approximately
$53.7 million, a majority of which is invested in money market funds at several
highly rated financial institutions.
During 2021 and 2022, our primary sources of funding have been milestone
payments from 3D Medicines and proceeds from the sale of our common stock and
other securities. In November 2020, June 2021 and August 2021, we received $12
million, $6 million and $3 million, respectively, in upfront and milestone
payments from 3D Medicines pursuant to the 3D Medicines Agreement with them. In
October 2022, we received a $6 million milestone payment from 3D Medicines. On
February 18, 2021, we received approximately $21 million from the purchase by
Eshelman Ventures of 2,875,000 shares of our common stock. On September 4, 2020,
we entered into an equity distribution agreement (the "Equity Distribution
Agreement") with Piper Sandler and Cantor Fitzgerald to sell shares of our
common stock, from time to time, through an "at the market offering" program
having an aggregate offering price of up to $60,000,000 through which Piper
Sandler and Cantor Fitzgerald will act as sales agents. During the year ended
December 31, 2021, we sold 1,432,627 shares of common stock for net proceeds of
$9.8 million under the Equity Distribution Agreement. On January 5, 2022, we
received approximately $9.9 million in net proceeds from the purchase by
Eshelman Ventures, LLC of pre-funded warrants to purchase up to 4,545,455 shares
of our common stock. In March 2022, we received approximately $9.3 million in
net proceeds, in the aggregate, from the purchase by Eshelman Ventures, LLC and
a single healthcare-focused institutional investor of 3,185,216 shares of our
common stock, 1,665,025 March Pre-Funded Warrants and March Common Stock
Warrants to purchase up to 4,850,241 shares of our common stock in a registered
direct offering. In October 2022, we received approximately $40 million in
net proceeds from a private placement offering from new biotechnology investors,
existing investors, our management and certain of our Directors for the issuance
and sale of an aggregate of 45,178,811 shares of our common stock (or October
Pre-Funded Warrants in lieu thereof) and October Common Warrants to purchase up
to an aggregate of 45,178,811 shares of common stock in a private placement
offering priced at-the-market under Nasdaq rules. The purchase price per share
and accompanying October Common Warrant was $0.9199 for all investors who
participated in the deal (or $0.9198 per October Pre-Funded Warrant and
accompanying October Common Warrant). During the year ended December 31, 2022,
we sold 54,763 shares of common stock for net proceeds of $0.1 million under the
Equity Distribution Agreement.
As of December 31, 2022, we had cash and cash equivalents of approximately $53.7
million. We believe that our existing cash and cash equivalents will be
sufficient to sustain operations beyond our PROC Phase 3 top line results
and into the fourth quarter of 2023 and that we will need to obtain additional
financing in order to advance our clinical development program to later stages
of development, build out our pipeline and fund operations beyond the fourth
quarter of 2023. We intend to provide financing for the foregoing by
seeking funds through equity or debt financings, collaborative or other
arrangements with corporate sources, or through other sources of financing.
These factors raised substantial doubt about our ability to continue as a going
concern. The consolidated financial statements included in this Annual Report on
Form 10-K do not include any adjustments relating to the recoverability of the
recorded assets or the classification of liabilities that may be necessary
should we be unable to continue as a going concern. Although management has been
successful in raising capital in the past, there can be no assurance that we
will be successful or that any needed financing will be available in the future
at terms acceptable to us. Our failure to raise capital as and when needed
could have a negative impact on our financial condition and our ability to
complete clinical trials and pursue our business strategies. We anticipate that
we will need to raise substantial additional capital, the requirements of which
will depend on many factors, including:
• the rate of progress, cost of our clinical studies and results of our clinical
studies, including the need to conduct additional trials if requested by the
FDA;
• the timing of, and costs involved in, seeking and obtaining approvals from the
FDA and other regulatory authorities;
• the cost of preparing to manufacture on a larger scale;
• the costs of commercialization activities if any future product candidate is
approved, including product sales, marketing, manufacturing and distribution;
• the degree and rate of market acceptance of any products launched by us or
future partners;
• the costs of filing, prosecuting, defending and enforcing any patent claims
and other intellectual property rights;
• our ability to enter into additional collaboration, licensing,
commercialization or other arrangements and the terms and timing of such
arrangements; and
• the emergence of competing technologies or other adverse market developments.
If we are unable to raise additional funds when needed, or if funds are raised
on terms that are not favorable to us, we may be required to delay, reduce, or
terminate some or all of our development programs and clinical trials. We may
also be required to sell or license our technologies or clinical product
candidates or programs that we would prefer to develop and commercialize
ourselves.

Cash flows
The following table sets forth the primary sources and uses of cash and cash
equivalents for each of the periods presented below:
Year Ended
December 31,
2022 2021
(In thousands)
Net cash (used in) provided by:
Operating activities $ (65,079 ) $ (32,177 )
Investing activities (11 ) -
Financing activities 59,369 31,061
Net decrease in cash and cash equivalents $ (5,721 ) $ (1,116 )
Cash used in operating activities
Net cash used in operating activities was $65.1 million and $32.2 million during
the years ended December 31, 2022 and 2021, respectively, which was primarily
due to the use of funds in our operations related to the development of
batiraxcept, our product candidate. Cash used in operating activities in 2022
increased compared to the year ended December 31, 2021 due primarily to the ramp
up in our Phase 3 trial of batiraxcept in PROC along with continuing costs
related to our trial of our second oncology indication, ccRCC and our third
oncology indication, pancreatic adenocarcinoma. There were also significant
increased CMC manufacturing activities during 2022 in order to prepare for our
BLA filing at the end of 2023.
Cash used in investing activities
Net cash used in investing activities during the years ended December 31, 2022
and 2021 was $11 thousand and $0, respectively.
Cash provided by financing activities
Net cash provided by financing activities was $59.4 million and $31.1 million
during the years ended December 31, 2022 and 2021, respectively. Financing
activities related to the year ended December 31, 2022 included a registered
direct offering of our securities with proceeds of $9.3 million, issuance of
Pre-Funded Warrants with proceeds of $9.9 million, at the market offering
proceeds of $0.1 million, and a private placement financing with net proceeds of
approximately $40.0 million. Financing activities related to the year ended
December 31, 2021 included a registered direct offering with proceeds of $20.9
million along with at the market offering proceeds of $9.8 million.
Critical Accounting Estimates
Our discussion and analysis of our financial condition and results of operations
is based upon financial statements that we have prepared in accordance with
accounting principles generally accepted in the United States of America, or
GAAP. The preparation of these financial statements requires management to make
estimates and judgments that affect the reported amounts of assets, liabilities
and expenses, and related disclosures. On an on-going basis, we evaluate these
estimates, including those related to revenue recognition and estimated future
research and development expenses, warrant liabilities and share-based
compensation. Estimates are based on historical experience, information received
from third parties and on various other assumptions that are believed to be
reasonable under the circumstances, the results of which form the basis for
making judgments about the carrying values of assets and liabilities that are
not readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions. Historically, revisions to
our estimates have not resulted in a material change to the financial
statements.
63
--------------------------------------------------------------------------------
Table of Contents
Collaboration Revenue
We enter into out-license and collaboration agreements under which we license
certain rights to our product candidate to third parties and which to date are
within the scope of ASC 606. The terms of these arrangements typically include
payment to us of one or more of the following: non-refundable, up-front license
fees; development, regulatory, and commercial milestone payments; payments for
manufacturing supply services we provide through our contract manufacturers; and
royalties on net sales of licensed products. Each of these payments may result
in license, collaboration and other revenue, except for revenues from royalties
on net sales of licensed products, which are classified as royalty revenues.
For elements of our collaboration agreements that are accounted for pursuant to
ASC 606, we must develop assumptions that require judgment to determine whether
the individual promises should be accounted for as separate performance
obligations or as a combined performance obligation, and to determine the
stand-alone selling price for each performance obligation identified in the
contract. We use key assumptions to determine the stand-alone selling price,
which may include forecasted revenues, development timelines, reimbursement
rates for personnel costs, discount rates, and probabilities of technical and
regulatory success. If the license to our intellectual property is determined to
be distinct from the other performance obligations identified in an out-license
and collaboration arrangement, we recognize revenue from non-refundable,
up-front fees allocated to the license when the license is transferred to the
customer and the customer is able to use and benefit from the license. For
licenses that are bundled with other promises, we utilize judgment to assess the
nature of the combined performance obligation to determine whether the combined
performance obligation is satisfied over time or at a point in time and, if over
time, the appropriate method of measuring progress for purposes of recognizing
revenue from non-refundable, up-front fees. With regard to the 3D Medicines
collaboration agreements, we recognize revenue related to amounts allocated to
the identified performance obligation on a proportional performance basis as the
underlying services are performed.
The preceding estimates and judgments materially affect our recognition of
collaboration revenues. Changes in our estimates of forecasted development costs
could impact proportional performance percentages and could have a material
effect on collaboration revenue recorded in the period in which we determine
that change occurs.
Clinical Trial Accruals
Our clinical trial accruals are based on estimates of patient enrollment and
related costs at clinical investigator sites as well as estimates for the
services received and efforts expended pursuant to contracts with multiple
research institutions and CROs that conduct and manage clinical trials on the
Company's behalf.
Our estimates of preclinical and clinical trial expenses are based on the
services performed, pursuant to contracts with research institutions and
CROs that conduct and manage preclinical studies and clinical trials on
our behalf. In accruing service fees, we estimate the time period over which
services will be performed and the level of patient enrollment and activity
expended in each period. If the actual timing of the performance of services or
the level of effort varies from the estimate, we will adjust the accrual
accordingly. Payments made to third parties under these arrangements in advance
of the receipt of the related services are recorded as prepaid expenses until
the services are rendered.
The preceding estimates and judgment materially affect our research and

Stock-based Compensation Expense
For purposes of calculating stock-based compensation, we estimate the fair value
of share-based compensation awards using a Black-Scholes option-pricing model.
The determination of the fair value of stock-based compensation awards utilizing
the Black-Scholes model is affected by our stock price and a number of
assumptions, including but not limited to expected stock price volatility over
the term of the awards and the expected term of stock options.
If factors change and we employ different assumptions, share-based compensation
expense may differ significantly from what we have recorded in the past. If
there is a difference between the assumptions used in determining stock-based
compensation expense and the actual factors which become known over time, we may
change the input factors used in determining stock-based compensation expense
for future grants. These changes, if any, may materially impact our results of
operations in the period such changes are made. For actual forfeitures, we
recognize the adjustment to compensation expense in the period the forfeitures
occur.
Warrant Liability
The Company estimates the fair value of these liabilities using assumptions that
are based on the individual characteristics of the warrants on the valuation
date and reporting date. The Company uses the Black-Scholes option-pricing model
and the fair value of the underlying stock adjusted for discount for lack of
marketability, when applicable, to determine the fair value of these
liabilities. The valuation model is based on inputs as of the valuation dates,
including the estimated volatility of our stock, the remaining contractual term
of the warrants and the risk-free interest rates and various other factors.
If factors change and we employ different assumptions, the warrant liability and
other income/expense may differ significantly from what we have recorded in the
past. If there is a difference between the assumptions used in determining the
warrant liability and the actual factors which become known over time, we might
change our inputs used in the valuation model. These changes, if any, may
materially impact our results of operations in the period such changes are made.
