Overview



We are a late-stage, clinical biopharmaceutical company dedicated to
discovering, developing and commercializing first-in-class, oral biological
therapeutics to treat patients with rare and severe metabolic and kidney
disorders. Our lead product candidate, reloxaliase (formerly known as ALLN-177),
is currently being evaluated in a pivotal Phase 3 clinical program for the
treatment of enteric hyperoxaluria, a metabolic disorder characterized by
markedly elevated urinary oxalate levels and commonly associated with kidney
stones, chronic kidney disease ("CKD") and other serious kidney disorders. There
are currently no approved therapies for the treatment of enteric hyperoxaluria.
We are also developing ALLN-346 for the treatment of hyperuricemia and gout in
the setting of advanced CKD. We completed a Phase 1b multiple-ascending dose
study in the second quarter of 2021 and recently initiated dosing for the first
of two planned Phase 2a studies. Initial data from the Phase 2a program are
expected during the fourth quarter of 2021.

We have conducted a robust clinical development program of reloxaliase,
including three Phase 2 clinical trials and the first of two planned Phase 3
clinical trials, which have demonstrated significant reductions in UOx excretion
in patients with enteric hyperoxaluria. Reloxaliase has also been well tolerated
in all studies conducted to date. We initiated URIROX-1TM (URIROX-1, formerly
Study 301), the first of our two Phase 3 clinical trials in support of our
planned Biologic License Application, or BLA, for reloxaliase in patients with
enteric hyperoxaluria in March 2018. In November 2019, we reported that the
primary endpoint in the URIROX-1 study had been met, with a mean reduction of
22.6% in average 24-hour UOx excretion measured during Weeks 1-4 among patients
treated with reloxaliase, compared to a mean reduction of 9.7% in the placebo
group (least square, or LS, mean treatment difference of -14.3%, p=0.004). In
the fourth quarter of 2018, we initiated URIROX-2TM (URIROX-2, formerly Study
302), our second pivotal Phase 3 trial of reloxaliase in patients with enteric
hyperoxaluria.

In February 2020, following engagement with the U.S. Food and Drug
Administration, or FDA, we announced that we reached agreement with the FDA on a
streamlined design for URIROX-2, based on the high rate of on-study kidney stone
events and the UOx results observed in the completed URIROX-1 trial, which
enrolled essentially the same patient population as URIROX-2. The FDA has also
advised us that it agrees that, if positive, biomarker data on 24-hour UOx
excretion in URIROX-1 and URIROX-2 would be used for a BLA submission for
reloxaliase using the accelerated approval regulatory pathway. For the long-term
follow-up phase of the trial, subjects would continue in URIROX-2 for a minimum
treatment period of two years to confirm clinical benefit post-approval,
including the ability of reloxaliase to reduce the incidence and severity of
kidney stone disease and renal impairment.

The execution and enrollment of the URIROX-2 trial have been adversely affected
by the COVID-19 pandemic. We had previously planned to conduct the first interim
analysis of the URIROX-2 study after 130 subjects had been treated for at least
six months and had estimated the timing of this analysis to be in the second or
third quarter of 2022. In July 2021, given the adverse impact of the COVID-19
global pandemic on the rate of patient enrollment in this global study, and
considering as



                                       16

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


well that enrollment in this study began in 2019, we modified our plans and now
expect to conduct the first interim analysis, which will include all subjects
who were enrolled in the trial as of the end of November 2021, during the first
quarter of 2022.  We estimate that this revised interim analysis would include
UOx data during weeks 1-4 for approximately 80 patients but would not include
sufficient data to evaluate UOx levels during weeks 16-24 or the blinded rate of
kidney stone events, as previously planned.  We plan to submit our revised plan
for the first interim analysis to the FDA as part of our planned update to the
URIROX-2 statistical analysis plan and adaptive design charter. The revised
interim analysis, which will be conducted by an independent data monitoring
committee, will assess whether the study continues to be adequately powered to
evaluate efficacy against the primary endpoint, the change in UOx levels during
weeks 1-4 versus baseline, with the planned enrollment of 200 subjects, or
whether the study size should be increased. As previously planned, the interim
analysis will also include an assessment of futility with respect to the primary
endpoint. We do not anticipate any changes to the planned second interim
analysis, which will also include an assessment of the secondary endpoint of
change in UOx levels during weeks 16-24 and of unblinded kidney stone events.
The second interim analysis is expected to be conducted once 200 subjects have
reached six months of treatment and is designed to enable a potential filing for
accelerated approval for reloxaliase.

In addition to our Phase 3 program of reloxaliase for enteric hyperoxaluria, we
also evaluated reloxaliase in Study 206, a Phase 2 basket trial in adults and
adolescents with primary hyperoxaluria or enteric hyperoxaluria with advanced
CKD and elevated plasma oxalate levels (hyperoxalemia), which we initiated in
March 2018. The data from this study have been published in Nephrology Dialysis
Transplantation (Pfau 2021). Based on the substantial reductions from baseline
to Weeks 4- 12 in both UOx and plasma oxalate, or POx, observed in subjects with
enteric hyperoxaluria and advanced CKD, we obtained feedback from the FDA on
potential expedited approval pathways for reloxaliase in this patient
population. The FDA recognized that the high oxalate burden in these patients
represents a serious, life-threatening condition, which is a requirement for
considering an expedited approval pathway. However, the FDA advised us that
reloxaliase would not currently qualify for breakthrough designation in this
patient population based on the lack of placebo-controlled data from open-label
Study 206. In this setting, and given our current financial resources, we remain
focused on executing URIROX-2 and plan to evaluate potential clinical
development of reloxaliase in patients with enteric hyperoxaluria and advanced
CKD in the future.

In addition, we have designed our second product candidate, ALLN-346, an orally
administered, novel, urate degrading enzyme, for patients with hyperuricemia and
gout in the setting of advanced CKD. Hyperuricemia, or elevated levels of uric
acid in the blood, results from overproduction or insufficient excretion of
urate, or often a combination of the two. We have conducted two preclinical
proof-of-concept studies that support the potential of ALLN-346 as an oral
therapy for the treatment of hyperuricemia in patients with gout and associated
CKD. We filed an IND for ALLN-346 with the FDA in December 2019. We have
conducted both single ascending dose and multiple ascending dose studies of
ALLN-346 in healthy volunteers. In both studies, ALLN-346 was well tolerated,
and there were no safety signals observed. During the second half of 2021 we
plan to conduct a Phase 2a program for ALLN-346, consisting of a 7-day inpatient
study in patients with hyperuricemia and a 14-day outpatient study in patients
with hyperuricemia and gout. We recently initiated dosing for the first of the
two planned Phase 2a studies.

On July 16, 2021, we completed a registered direct offering, in which we issued
and sold 17,416,096 shares of our common stock, pre-funded warrants to purchase
up to an aggregate of 3,941,648 shares of our common stock in lieu of shares of
common stock and warrants to purchase up to 10,678,872 shares of our common
stock through a Securities Purchase Agreement. The combined price of each share
of common stock and accompanying warrant to purchase one-half of a share was
$1.311. The purchase price of each pre-funded warrant was $1.301, which was the
combined purchase price per share of common stock and accompanying warrant,
minus $0.01. Gross proceeds of the transaction were $28.0 million. As a result
of the registered direct offering, we received approximately $25.4 million after
deducting estimated offering costs. Each warrant is exercisable for one share of
our common stock at an exercise price of $1.25 per share. The warrants are
immediately exercisable and expire on July 16, 2026. Each pre-funded warrant is
exercisable for one share of common stock at an exercise price of $0.01 per
share. The pre-funded warrants are immediately exercisable and may be exercised
at any time until all pre-funded warrants are exercised in full. All pre-funded
warrants were exercised on July 16, 2021.

During the first quarter of 2021, we issued and sold 6,058,318 shares of our
common stock under the Cowen ATM Agreement at a weighted average price of $1.99
per share for net proceeds of $11.7 million. On March 29, 2021, we terminated
the Cowen ATM Agreement and entered into the B. Riley ATM Agreement. During the
second quarter of 2021, we issued and sold 1,650,988 shares of our common stock
under the B. Riley ATM Agreement, at a weighted average price of $1.25 per share
for net proceeds of $1.8 million.

On December 4, 2020, we completed a public underwritten offering of 11,960,000
shares of our common stock, including the exercise in full of the underwriter's
option to purchase an additional 1,560,000 shares of common stock, at a price to
the public of $1.25 per share for net proceeds of $13.5 million.



                                       17

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


On July 30, 2020, we completed a public underwritten offering of 5,894,191
shares of our common stock, including the exercise in full of the underwriter's
option to purchase an additional 768,807 shares of common stock, at a price to
the public of $1.30 per share for net proceeds of $6.7 million.

On June 5, 2020, we completed a registered direct offering, in which we issued
and sold 7,317,074 shares of our common stock, at a purchase price of $2.05 per
share, for net proceeds of $13.7 million through a securities purchase agreement
with certain institutional and accredited investors. The shares of common stock
sold in this offering were offered by us pursuant to our shelf registration
statement on Form S-3 filed with the SEC, which was declared effective on
December 26, 2018 and a prospectus supplement thereunder filed on June 5, 2020.

Our operations to date have been primarily focused on organizing and staffing
our company, business planning, raising capital, developing our technology,
identifying potential product candidates, manufacturing our product candidates
and conducting preclinical studies and clinical trials of reloxaliase and
ALLN-346. We do not have any products approved for sale and have not generated
any revenue to date. As of June 30, 2021, we had cash and cash equivalents
totaling $26.7 million.

We have incurred significant net operating losses in every year since our
inception and expect to continue to incur significant expenses and increasing
operating losses for the foreseeable future. Our net losses may fluctuate
significantly from quarter to quarter and year to year. Our net losses were
$14.0 million and $7.0 million for the three months ended June 30, 2021 and
2020, respectively, and $25.6 million and $14.6 million for the six months ended
June 30, 2021 and 2020, respectively. As of June 30, 2021, we had an accumulated
deficit of $223.4 million. We anticipate that our expenses will increase
significantly as we:

• conduct clinical trials of our lead product candidate, reloxaliase;

• manufacture additional material for our pivotal Phase 3 clinical program

and potential future clinical studies we might conduct for our product

candidates;

• scale up our manufacturing process for reloxaliase to prepare for the


       filing of a potential Biologics License Application, or BLA, and
       commercialization if our clinical development program is successful;

• advance the development and conduct future clinical trials of ALLN-346;

• conduct research on the discovery and development of additional product

candidates;

• seek regulatory and marketing approvals for product candidates that


       successfully complete clinical trials, if any;


    •  establish a sales, marketing and distribution infrastructure to

commercialize any products for which we may obtain regulatory approval in

geographies in which we plan to commercialize our products ourselves;




  • maintain, expand and protect our intellectual property portfolio;


    •  hire additional staff, including clinical, scientific, technical,

operational, and financial personnel, to execute our business plan; and

• add clinical, scientific, operational, financial and management information

systems to support our product development and potential future

commercialization efforts, and to enable us to operate as a public company.




We do not expect to generate revenue from product sales unless and until we
successfully complete development and obtain regulatory approval for a product
candidate. Additionally, we currently use contract research organizations, or
CROs, and contract manufacturing organizations, or CMOs, to carry out our
preclinical and clinical development activities. We do not yet have a sales
organization. If we obtain regulatory approval for our product candidates, we
expect to incur significant commercialization expenses related to product sales,
marketing, manufacturing and distribution. Furthermore, we expect to incur
additional costs associated with operating as a public company. Accordingly, we
may seek to fund our operations through public or private equity or debt
financings or other sources, including strategic collaborations. We may,
however, be unable to raise additional funds or enter into such other
arrangements when needed on favorable terms or at all. Our failure to raise
capital or enter into such other arrangements as and when needed would have a
negative impact on our financial condition and our ability to develop our
current product candidates, or any additional product candidates, if developed.

Financial Operations Overview

Revenue



To date, we have not generated any revenue from product sales or any other
source and do not expect to generate any revenue from the sale of products for
the foreseeable future. If our development efforts for reloxaliase or other
product candidates that we may develop in the future are successful and result
in marketing approval or collaboration or license



                                       18

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

agreements with third parties, we may generate revenue in the future from a combination of product sales or payments from such collaboration or license agreements.

Research and Development Expenses



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

• employee-related expenses, including salaries, benefits and stock-based

compensation expense;

• costs incurred under agreements with third parties, including CROs, that

conduct research and development, preclinical studies and clinical trials


       on our behalf;


    •  costs related to production of preclinical and clinical materials,
       including fees paid to CMOs;

• consulting, licensing and professional fees related to research and

development activities;

• costs of purchasing laboratory supplies and non-capital equipment used in

our research and development activities;

• costs related to compliance with clinical regulatory requirements; and

• facility costs and other allocated expenses, which include expenses for


       rent and maintenance of facilities, insurance, depreciation and other
       supplies.


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 clinical site
activations, patient enrollment, 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 may be reflected in our consolidated financial statements as
prepaid or accrued research and development expenses. Nonrefundable advance
payments for goods or services to be received in the future for use in research
and development activities are deferred and capitalized, even when there is no
alternative future use for the research and development. The capitalized amounts
are expensed as the related goods are delivered or the services are performed.

The following summarizes our most advanced current research and development programs:

• reloxaliase is our lead product candidate which we are developing for the

treatment of enteric hyperoxaluria. A substantial majority of our research


       and development costs to date have been used to fund this program.

• ALLN-346 is our second product candidate which we are developing for the

treatment of hyperuricemia and gout in the setting of CKD.

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



The following table summarizes our research and development expenses by program
(in thousands):

                                       19

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




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, primarily due to the increased
size and duration of later-stage clinical trials. Since inception, we have
incurred $100.7 million of external research and development costs for
reloxaliase and $13.4 million of external research and development costs for
ALLN-346. We expect that our research and development costs will continue to
increase for the foreseeable future as we conduct URIROX-2 and initiate
additional clinical trials of reloxaliase, scale our manufacturing processes and
advance development of ALLN-346.

The successful development of reloxaliase, ALLN-346 and other potential future
product candidates is highly uncertain. Accordingly, at this time, we cannot
reasonably estimate or know the nature, timing and costs of the efforts that
will be necessary to complete the development of these product candidates. We
are also unable to predict when, if ever, we will generate revenue and material
net cash inflows from the commercialization and sale of any of our product
candidates for which we may obtain marketing approval. We may never succeed in
achieving regulatory approval for any of our product candidates. The duration,
costs and timing of preclinical studies, clinical trials and development of our
product candidates will depend on a variety of factors, including:

• successful enrollment in, and completion of, clinical trials for reloxaliase;

• successful data from our clinical program of reloxaliase that supports an

acceptable benefit-risk profile of reloxaliase in the intended populations;

• successful enrollment in, and completion of, clinical trials for ALLN-346;

• establishing an appropriate safety profile for any potential future product


       candidates with studies to enable the filing of investigational new drug
       application, or INDs;

• approval of INDs for any potential future product candidate to commence

planned or future clinical trials;

• significant and changing government regulation and regulatory guidance;

• timing and receipt of marketing approvals from applicable regulatory

authorities;

• making arrangements with CMOs for third-party commercial manufacturing of

our product candidates;

• obtaining and maintaining patent and other intellectual property protection

and regulatory exclusivity for our product candidates;

• commercializing the product candidates, if and when approved, whether alone

or in collaboration with others;

• acceptance of the product, if and when approved, by patients, the medical

community and third-party payors; and

• maintenance of a continued acceptable safety profile of the drugs following

approval.

A change in the outcome of any of these variables with respect to the development, manufacture or commercialization enabling activities of any of our product candidates could mean a significant change in the costs, timing and viability associated with the development of that product candidate.

General and Administrative Expenses



General and administrative expenses consist primarily of salaries and other
related costs, including stock-based compensation, for personnel in executive,
finance, accounting, business development and human resources functions. Other
significant costs include directors' and officers' insurance, facility costs not
otherwise included in research and development expenses, legal fees relating to
patent and corporate matters and professional fees for accounting, auditing, tax
and consulting services.

We expect that our general and administrative expenses will increase in the
future to support continued research and development activities and potential
commercialization of our product candidates. These increases will likely include
increased costs related to the hiring of additional personnel and fees to
outside consultants, attorneys and accountants, among other expenses.

Interest Expense



Interest expense primarily consists of interest income earned on our cash and
cash equivalents, interest expense incurred on our credit facility and amortized
debt discount related to debt issuance costs.



                                       20

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

Other Expense, Net



Other expense, net, consists of amount of a success fee paid to PWB at the time
the conditions required to trigger the success fee as defined in the PWB Loan
Agreement were met and gain (loss) on foreign currency transactions.

Critical Accounting Policies and Use of Estimates



Our management's discussion and analysis of financial condition and results of
operations is based on our consolidated financial statements, which have been
prepared in accordance with U.S. GAAP. The preparation of these financial
statements requires us to make estimates and judgments that affect the reported
amounts of assets, liabilities and expenses and the disclosure of contingent
assets and liabilities in our consolidated financial statements during the
reporting periods. These items are monitored and analyzed by us for changes in
facts and circumstances, and material changes in these estimates could occur in
the future. We base our estimates on historical experience, known trends and
events, and on various other factors that we believe are reasonable under the
circumstances, the results of which form the basis for making judgments about
the carrying value of assets and liabilities that are not readily apparent from
other sources. Changes in estimates are reflected in reported results for the
period in which they become known. Actual results may differ materially from
these estimates under different assumptions or conditions.

Our significant accounting policies are described in detail in the notes to our
consolidated financial statements appearing in the Annual Report filed on Form
10-K for the year ended December 31, 2020. There have been no changes to our
significant accounting policies.

The $6.3 million increase in research and development expense was primarily attributable to the following:

• Our clinical development external costs increased by $4.1 million from $1.0

million for the three months ended June 30, 2020 to $5.1 million for the

three months ended June 30, 2021:

o Our URIROX-2 costs increased $2.6 million from $0.7 million for the

three months ended June 30, 2020 to $3.3 million for the three months


          ended June 30, 2021. During the first half of 2020, we limited the
          opening of new trial sites for the ongoing URIROX-2 trial while we

assessed revisions to the study design and sought additional funds to

support the development of reloxaliase. During the second half of 2020

we began expanding URIROX-2 to additional geographies and clinical trial


          sites; and


      o   We incurred $1.4 million of costs for our ALLN-346 program during the

three months ended June 30, 2021, for which there were no comparable

costs incurred during the three months ended June 30, 2020. In April

2021, we initiated a Phase 1b multiple ascending dose trial in healthy

volunteers and announced initial data from this study in July 2021. We

incurred $0.6 million of clinical costs for this trial during the three


          months ended June 30, 2021. In addition, we incurred $0.7 million of
          start-up related costs for our Phase 2a program.


    •  Our manufacturing external costs increased by $1.3 million from $0.4
       million for the three months ended June 30, 2020 to $1.7 million for the
       three months ended June 30, 2021, primarily due to increased costs
       associated with reloxaliase; and

• Our employee compensation and benefits costs increased $0.6 million from

$1.9 million for the three months ended June 30, 2020 to $2.6 million for

the three months ended June 30, 2021, primarily due to an increase in

research and development headcount from 19 employees at June 30, 2020 to 34

employees at June 30, 2021.

General and Administrative Expenses



General and administrative expense increased $0.8 million from $2.8 million for
the three months ended June 30, 2020 to $3.6 million for the three months ended
June 30, 2021. The following table summarizes our general and administrative
expenses for the three months ended June 30, 2021 and 2020 (in thousands):



                                                    Three Months Ended June 30,          Dollar

Total general and administrative expenses $ 3,597 $


 2,751     $       846

General and administrative expense included the following:

• Our employee compensation and benefits costs were $1.8 million and $1.7

million for the three months ended June 30, 2021 and 2020, respectively;

• Our consulting and professional services costs increased $0.4 million for


       the three months ended June 30, 2021. The increase is primarily due to a
       $0.2 million increase in consulting costs, a $0.1 million increase in

investor relations costs and $0.1 million of recruiting costs for the three


       months ended June 30, 2021, for which there were no comparable costs for
       the three months ended June 30, 2020; and

• Our other costs increased $0.2 million for the three months ended June 30,

2021, primarily due to an increase in insurance costs.

Interest Income (Expense), net



Interest income (expense), net consists of interest income earned on our cash
and cash equivalents and interest expense incurred on our outstanding debt. Net
interest expense increased $0.2 million for the three months ended June 30, 2021
due to increased interest expense associated with amounts outstanding under the
Pontifax Agreement. In September 2020, we terminated the PWB Agreement, under
which we were paying an annualized interest rate of 5.0% and entered into the
Pontifax Agreement, under which we are paying an annualized interest rate of
9.0% on outstanding borrowings. In addition, we are paying Pontifax an
annualized fee of 1.0% for the $5.0 million available under the Credit Line of
the Pontifax Agreement, no amount of which has been withdrawn as of June 30,
2021.

Research and Development Expenses



Research and development expense increased by $9.5 million from $8.5 million for
the six months ended June 30, 2020 to $17.9 million for the six months ended
June 30, 2021. The following table summarizes our research and development
expenses for the six months ended June 30, 2021 and 2020 (in thousands):

849

Total research and development expenses $ 17,942 $ 8,454

   $ 9,488

The $9.5 million increase in research and development expense was primarily attributable to the following:

• Our clinical development external costs increased by $6.4 million from $2.2

million for the six months ended June 30, 2020 to $8.6 million for the six

months ended June 30, 2021:

o Our URIROX-2 costs increased $5.2 million from $1.3 million for the six

months ended June 30, 2020 to $6.5 million for the six months ended June

30, 2021. During the first half of 2020, we limited the opening of new

trial sites for the ongoing URIROX-2 trial while we assessed revisions


          to the study design and sought additional funds to support the
          development of reloxaliase. During the second half of 2020 we began
          expanding URIROX-2 to additional geographies and clinical trial sites;
          and


      o   We incurred $1.5 million of costs for our ALLN-346 program during the

six months ended June 30, 2021, for which there were no comparable costs

incurred during the six months ended June 30, 2020. In April 2021, we

initiated a Phase 1b multiple ascending dose trial in healthy volunteers

and announced initial data from this study in July 2021. We incurred

$0.8 million of clinical costs for this trial during the six months

ended June 30, 2021. In addition, we incurred $0.7 million of start-up

related costs for our Phase 2a program.

• Our manufacturing external costs increased by $1.9 million from $1.1

million for the six months ended June 30, 2020 to $3.0 million for the six

months ended June 30, 2021.

o Formulation and development related costs for reloxaliase increased $1.3


          million from $0.5 million for the six months ended June 30, 2020 to $1.8
          million for the six months ended June 30, 2021; and


      o   Formulation and development related costs for ALLN-346 increased $0.3
          million from $0.4 million for the six months ended June 30, 2020 to $0.7
          million for the six months ended June 30, 2021.




                                       23

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

• Our employee compensation and benefits costs increased by $0.3 million from

$4.4 million for the six months ended June 30, 2020 to $4.7 million for the

six months ended June 30, 2021. The increase is primarily due to an

increase in headcount from 19 employees at June 30, 2020 to 34 employees at

June 30, 2021, partially offset by a decrease in stock-based compensation

costs.

We expect that our research and development expenses will increase in future periods as we continue our clinical development of reloxaliase, scale our manufacturing processes for reloxaliase and advance development of ALLN-346.

General and Administrative Expenses



General and administrative expense increased by $1.5 million from $5.6 million
for the six months ended June 30, 2020 to $7.2 million for the six months ended
June 30, 2021. The following table summarizes our general and administrative
expenses for the six months ended June 30, 2021 and 2020 (in thousands):



                                                    Six Months Ended June 30,          Dollar

Total general and administrative expenses $ 7,155 $ 5,629 $ 1,526

The increase in general and administrative expense was primarily attributable to the following:

• Our employee compensation and benefits costs increased by $0.3 million from

$3.3 million for the six months ended June 30, 2020 to $3.6 million for the

six months ended June 30, 2021, primarily due to an increase in the number

of employees;

• Our consulting and professional services costs increased by $0.6 million

from $1.2 million for the six months ended June 30, 2020 to $1.9 million

for the six months ended June 30, 2021. The increase was primarily due to a

$0.3 million increase in consulting costs and $0.3 million of recruiting


       costs for the six months ended June 30, 2021, for which there were no
       comparable costs for the six months ended June 30, 2020; and

• Our other costs increased by $0.5 million from $1.1 million for the six


       months ended June 30, 2020 to $1.6 million for the six months ended June
       30, 2021, primarily due to an increase in insurance costs.

Interest Income (Expense), net



Interest income (expense), net consists of interest income earned on our cash
and cash equivalents and interest expense charged on our outstanding debt. Net
interest expense increased $0.3 million for the six months ended June 30, 2021
due to increased interest expense associated with amounts outstanding under the
Pontifax Agreement.

Other Expense, net

Other expense, net consists of a success fee paid to PWB and gain (loss) on foreign currency transactions. Included in other expenses, net for six months ended June 30, 2020 was a success fee of $0.3 million paid to PWB.

Liquidity and Capital Resources

Sources of Liquidity



We have funded our operations from inception through June 30, 2021 through gross
proceeds of $96.0 million from sales of our convertible preferred stock, net
proceeds of $67.0 million from our IPO which was completed in November 2017, net
proceeds totaling $33.8 million from follow-on offerings of common stock during
2020, borrowings of $10.0 million under our credit facilities, and net proceeds
of $14.6 million and $1.8 million from the sale of our common stock under the
Cowen ATM Agreement and the B. Riley ATM Agreement, respectively. In addition,
on July 16, 2021, we received net proceeds of approximately $25.4 million from
the sale of common stock, pre-funded warrants and warrants to purchase common
stock, through a registered direct offering. Our total cash and cash equivalents
were $26.7 million as of June 30, 2021, which amount does not include the $25.4
million from the registered direct offering completed in July 2021.



                                       24

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


On May 6, 2021, we filed a shelf registration statement on Form S-3, which was
declared effective on May 12, 2021 (File No. 333-255837), for the offering of up
to $200 million in the aggregate of common stock, preferred stock, debt
securities, warrants and/or units ("securities") from time to time in one or
more offerings. As of the filing of this Quarterly Report on Form 10-Q, we have
not offered any securities pursuant to this shelf registration.

On September 29, 2020, we entered into a loan and security agreement with
Pontifax Medison Finance (Israel) L.P. and Pontifax Medison Finance (Cayman)
L.P. (together "Pontifax") ("Pontifax Agreement") providing up to $25.0 million
of borrowings through three facilities of a term loan. An initial loan ("Initial
Loan) of $10.0 million was advanced on September 29, 2020. A portion of these
proceeds were used to pay the remaining balance of our credit facility with PWB
and terminate the PWB Loan Agreement. We also have an additional $5.0 million
credit line ("Credit Line") available to us for withdrawal until September 29,
2021. We shall pay a fee of 1.0% per annum to Pontifax for the daily average
amount not withdrawn under the Credit Line. A third installment loan (Third
Installment Loan") of an additional $10.0 million was conditioned upon
achievement of one of the following milestones by no later than December 29,
2021: (i) we receive non-contingent, non-refundable gross proceeds from one or
more equity financings and/or strategic partnerships, in each case consummated
following the Closing Date, in the aggregate amount of at least $15.0 million
for all such equity financings and strategic partnerships or (ii) the 65th
patient has been enrolled in the URIROX-2 trial. During the three months ended
December 31, 2020, the additional $10 million under the Third Installment Loan
became available to us for withdrawal until December 29, 2021 when we satisfied
the milestone of at least $15 million of gross proceeds from equity
financings. Upon withdrawal of the Third Installment Loan, if withdrawn, we
shall pay Pontifax a one-time fee of 1.0% of the Third Installment Loan.

The Pontifax Agreement has a term of 48 months and an interest only period of 24
months. Amounts outstanding under the Pontifax Agreement have a fixed interest
rate of 9.0% per annum. Upon the expiration of the interest only period on
September 29, 2022, amounts borrowed will be repaid over eight equal quarterly
payments of principal and interest. At our option, we may prepay all or part of
the outstanding borrowings at any time without any prepayment premium or
penalty.

At the option of Pontifax, amounts outstanding under the Pontifax Agreement may
be converted at any time into shares of our common stock at a conversion price
of $4.10 per share. In addition, we have the right to convert at any time any
portion of the then outstanding borrowings and all accrued but unpaid interest
into shares of our common stock, at the applicable conversion price, subject to
the fulfillment of both of the following conditions: (i) during a period of 30
consecutive trading days prior to the date on which we provide notice of the
exercise of our conversion right, the closing price of our common stock was
higher than 1.4 times the applicable conversion price of the term loans on at
least 20 trading days, including on the trading day preceding the date we
provide notice of the exercise of our conversion right and (ii) the number of
shares of common stock issuable upon conversion by us shall not exceed the
average weekly number of shares of our common stock traded on the stock market
for the four weeks immediately preceding the date on which we provide notice of
the exercise of our conversion right.

The borrowings under the Pontifax Agreement are secured by a lien on all of our
assets except intellectual property. The Pontifax Agreement contains customary
representations, warranties and covenants by us, including negative covenants
restricting our activities, such as disposing of our business or certain assets,
incurring additional debt or liens or making payments on other debt, making
certain investments and declaring dividends, acquiring or merging with another
entity, engaging in transactions with affiliates or encumbering intellectual
property, among others. The obligations under the Pontifax Agreement are subject
to acceleration upon occurrence of specified events of default, including a
material adverse change in our business, operations or financial or other
condition.

Cash Flows

The following table provides information regarding our cash flows for the six months ended June 30, 2021 and 2020 (in thousands):

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

Net Cash Used in Operating Activities

The net 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 $21.4 million for the six months ended
June 30, 2021 compared to $15.3 million for the six months ended June 30, 2020.
The increase in cash used in operating activities of $6.1 million was
attributable to:

• An increase in net loss of $11.0 million, partially offset by;

• an increase of $5.1 million due to changes in the components of working

capital, including increases in accounts payable, accrued expenses and

operating lease liabilities, partially offset by decreases in prepaid

expenses and other assets; and

• a decrease in non-cash items of $0.2 million resulting primarily from a

decrease in stock-based compensation expense.

Net Cash Used in Investing Activities



Net cash used in investing activities of $0.5 million for the six months ended
June 30, 2021 consisted of purchases of property and equipment. We did not have
any cash flow activity relating to investment activities during the six months
ended June 30, 2020.

Net Cash Provided by Financing Activities



Net cash provided by financing activities was $13.5 million for the six months
ended June 30, 2021 compared to $11.7 million for the six months ended June 30,
2020. The net cash provided by financing activities for the six months ended
June 30, 2021 consisted of net proceeds of $11.7 million and $1.8 from the sale
of common stock under the Cowen ATM Agreement and the B. Riley ATM Agreement,
respectively. The net cash provided by financing activities for the six months
ended June 30, 2020 consisted primarily of $13.7 million of net proceeds from
the issuance and sale of 7,317,074 shares of our common stock completed on June
5, 2020 through a registered direct offering, partially offset by $2.0 million
for principal payments made on our credit facility with PWB, which was fully
repaid in September 2020.

Funding Requirements

We expect our expenses to increase in connection with our ongoing activities,
particularly as we continue the research and development for, initiate later
stage clinical trials for, and seek marketing approval for, our product
candidates. In addition, if we obtain marketing approval for any of our product
candidates, we expect to incur significant commercialization expenses related to
product sales, marketing, manufacturing and distribution. Accordingly, we will
need to obtain substantial additional funding in connection with our continuing
operations. If we are unable to raise capital when needed or on attractive
terms, we would be forced to delay, reduce or eliminate our research and
development programs or future commercialization efforts.

Going Concern



As of June 30, 2021, we had cash and cash equivalents totaling $26.7 million,
which amount does not include $25.4 million of net proceeds we received from our
registered direct offering of common stock, pre-funded warrants and warrants in
July 2021. Based on our current operating plans, we do not have sufficient cash
and cash equivalents to fund our operating expenses and capital expenditures for
at least the next 12 months from the filing date of this Quarterly Report. We do
believe that our cash and cash equivalents at June 30, 2021, along with the
$25.4 million of net proceeds received from the registered direct offering
completed in July 2021, will enable us to fund our operating expenses and
capital requirements into the second quarter of 2022. We will require additional
capital to sustain our operations, including our reloxaliase and ALLN-346
development programs, beyond that time. We are exploring opportunities to secure
additional funding through equity or debt financings or through collaborations,
licensing transactions or other sources. However, there can be no assurance that
we will be able to complete any such transaction on acceptable terms or
otherwise. Market volatility resulting from the COVID-19 pandemic or other
factors could also adversely impact our ability to access capital as and when
needed. The failure to obtain sufficient funds on commercially acceptable terms
when needed would have a material adverse effect on our business, results of
operations and financial condition and jeopardize our ability to continue
operations. These factors raise substantial doubt about our ability to continue
as a going concern. We may implement cost reduction strategies, which may
include amending, delaying, limiting, reducing, or terminating one or more of
our ongoing or planned clinical trials or development programs of our product
candidates. The accompanying condensed consolidated financial statements have
been prepared on a going

concern basis, which contemplates the realization of assets and satisfaction of
liabilities in the ordinary course of business for the foreseeable future. The
condensed consolidated financial statements do not include any adjustments
relating to the recoverability and classification of recorded asset amounts or
the amounts and classification of liabilities that might result from the outcome
of this uncertainty. Our future capital requirements will depend on many
factors, including;

• the costs of conducting clinical trials of reloxaliase, including any

unforeseen costs we may incur as a result of clinical trial delays due to

the COVID-19 pandemic or other causes;

• the costs of manufacturing additional material for our pivotal Phase 3

clinical program and potential future clinical studies we might conduct for

reloxaliase;




    •  the costs of scaling up our manufacturing process for reloxaliase to
       prepare for the potential filing of a BLA and commercialization if our
       clinical development program is successful;

• the costs of conducting future clinical trials and other development


       activities to advance ALLN-346;


    •  the scope, progress, results and costs of discovery, preclinical

development, laboratory testing and clinical trials for other potential

product candidates we may develop, if any;

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

• our ability to establish and maintain collaborations on favorable terms, if

at all;




    •  the achievement of milestones or occurrence of other developments that
       trigger payments under any collaboration agreements we might have at such
       time;

• the costs and timing of future commercialization activities, including


       product sales, marketing, manufacturing and distribution, for any of our
       product candidates for which we receive marketing approval;

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

product candidates, should any of our product candidates receive marketing

approval;

• the costs of preparing, filing and prosecuting patent applications,

obtaining, maintaining and enforcing our intellectual property rights and

defending intellectual property-related claims;

• the expansion of our workforce and associated costs as we expand our


       business operations and our research and development activities; and


  • the costs of operating as a public company.


Identifying potential product candidates and conducting preclinical testing 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 and achieve product sales. In addition,
our product candidates, if approved, may not achieve commercial success. Our
commercial revenues, if any, will be derived from sales of products that we do
not expect to be commercially available for many years, if at all. Accordingly,
we will need to continue to rely on additional financing to achieve our business
objectives. Adequate additional financing may not be available to us on
acceptable terms, or at all.

Until such time, if ever, as we can generate substantial product revenues, we
expect to finance our cash needs through a combination of equity offerings, debt
financings, collaborations, strategic alliances and licensing arrangements.
Except for the Credit Line and the Third Installment Loan under the Pontifax
Agreement, we do not have any committed external source of funds. To the extent
that we raise additional capital through the sale of equity or convertible debt
securities, your ownership interests may be diluted, and the terms of these
securities may include liquidation or other preferences that could adversely
affect your rights as a common stockholder. Additional debt financing, if
available, may involve agreements that include restrictive covenants that limit
our ability to take specific actions, such as incurring additional debt, making
capital expenditures or declaring dividends, that could adversely impact our
ability to conduct our business.

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