Statements," "Summary Risk Factors," and Part I, Item 1A. "Risk Factors" herein.

Company Overview



We are a clinical-stage biopharmaceutical company engaged in the science of
ribosome modulation, leveraging both our innovative TURBO-ZM™ chemistry
technology platform in an effort to develop novel Ribosome Modulating Agents
("RMAs") and its library of Eukaryotic Ribosome Selective Glycosides ("ERSGs"),
for the treatment of rare and ultra-rare premature stop codon diseases.
Premature stop codons are point mutations that disrupt the stability of the
impacted messenger RNA ("mRNA") and the protein synthesis from that mRNA.

Our lead clinical program, ELX-02, is currently in Phase 2 clinical development
for the treatment of cystic fibrosis ("CF") in patients with diagnosed nonsense
mutations and is being conducted at leading investigator sites in Europe, Israel
and the United States. As of the end of June 2021, we believe that we have
enrolled a sufficient number of patients to assess biological activity of
ELX-02. We expect to present data from the first four treatment arms of the
study before the end of 2021. The Cystic Fibrosis Foundation ("CFF") is
providing funding for a portion of this clinical trial program.

The FDA has granted orphan drug designation to ELX-02 for the treatment of nephropathic cystinosis, MPS I, Rett syndrome, and CF. In September 2021 the FDA granted Fast Track designation for ELX-02.

Acquisition of Zikani Therapeutics, Inc.





On April 1, 2021, the Company acquired Zikani Therapeutics, Inc. ("Zikani"), a
company in preclinical development and engaged in the science of ribosome
modulation, leveraging its innovative TURBO-ZMTM chemistry technology platform
to develop novel RMAs as potential therapeutics for diseases with limited
treatment options. The TURBO-ZMTM platform is designed to enable rapid synthesis
of novel compounds that can be optimized to modulate the ribosome in a disease
specific manner. The TURRBO-ZMTM synthetic chemistry platform can design oral
novel macrolide-based small molecules that are potent oral modulators with
favorable therapeutic indices. Macrolides are antibiotics that inhibit protein
synthesis in bacteria.



We expect the combined company to emerge as a leader in the science of ribosome
modulation through our complementary platforms and continued development of our
library of RMAs and ERSGs. ELX-02, is a small molecule drug candidate designed
to restore production of full-length functional proteins. The investigational
therapy has shown strong activity across a full range of mutations in CF
preclinical models. In Phase 1 testing, ELX-02 was generally well tolerated and
demonstrated high bioavailability with consistent pharmacokinetics across both
single and multiple-dose studies. The Phase 2 trials are designed to validate
the safety of ELX-02 and assess its biological activity.



With the strength of our ELX-02 program for CF, the acquisition of Zikani
provides us with the opportunity to amplify the potential of our innovative
science by developing a new class of therapies to treat diseases with limited to
no treatment options. The CFF has agreed to provide funding for a portion of
this research. Our preclinical programs are focused on select rare diseases
including inherited diseases, cancer caused by nonsense mutations, kidney
diseases, including autosomal dominant polycystic kidney disease, as well as
rare ocular genetic disorders. In addition, we plan to file an Investigational
New Drug ("IND") in 2022 for what could potentially become the first oral
therapy for protein restoration for patients with nonsense mutations in
Recessive Dystrophic Epidermolysis Bullosa ("RDEB") and Junctional Epidermolysis
Bullosa ("JEB"). RDEB is an incurable, extremely painful and often fatal skin
blistering condition caused by a lack of collagen type VII that is estimated to
affect more than 3,000 people worldwide. JEB is the most severe form of
Epidermolysis Bullosa, with most patients dying in infancy. By extending the
application of ribosomal RNA modulation to the readthrough of nonsense mutations
in tumor suppressor genes, we are also rapidly advancing preclinical research
for familial adenomatous polyposis (FAP), an inherited pre-cancerous colorectal
disease frequently caused by nonsense mutations in the

                                       22

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

adenomatous polyposis coli (APC) gene. We plan to target rare diseases including genetic diseases and cancers caused by nonsense mutations.





Nonsense mutations cause approximately 10-12% of rare inherited diseases. ELX-02
along with the TURBO-ZMTM library of compounds are anticipated to significantly
expand to include the treatment of many other rare diseases and certain cancers.



Under the terms of the Agreement and Plan of Merger (the "Merger Agreement"),
the Company issued 7,596,810 shares of common stock in exchange for all of the
issued and outstanding equity interests of Zikani. (the "Merger Consideration").



COVID-19

The ongoing COVID-19 pandemic and the measures that we, our employees,
consultants, suppliers, contract research organizations ("CROs"), and other
partners or governments may take in response to the pandemic may significantly
disrupt our business operations. We are working to ensure that we can operate
with minimal disruption and mitigate the impact of the pandemic on the health
and safety of our employees and the patients and healthcare professionals that
participate in our clinical trials. However, given the significant uncertainty
regarding the ongoing impact of the COVID-19 pandemic, there remains a risk that
we or our employees, contractors, suppliers, and other partners may be prevented
or prohibited from conducting business activities for indefinite periods of
time, for example due to a substantial percentage of personnel contracting the
virus or due to government-mandated restrictions.

While the pandemic has not to date had a material adverse impact on our
financial condition, and we have not had to furlough any employees, our clinical
trials were temporarily paused in March 021. As of August 2021, both Phase 2
clinical trials have resumed, and we believe that we have enrolled a sufficient
number of patients to assess biological activity of ELX-02. We continue to
monitor our operations, states of affairs in the regions in which we and our
business partners operate and conduct research and clinical trial activities,
and applicable government recommendations.

Research and development expense



Research and development expenses were $5.2 million for the three months ended
September 30, 2021, compared to $3.4 million for the same period in 2020, an
increase of $1.8 million. The increase was primarily related to a $0.8 million
increase in expenses related to subcontractors, consultants and advisors in
connection with continued development of ELX-02 due to the impact of the
COVID-19 pandemic on the corresponding prior year period expense, an increase in
salaries and other personnel related costs of $0.5 million, and an increase in
operational facilities of $0.5 million.

Research and development expenses were $15.0 million for the nine months ended
September 30, 2021 compared to $12.0 million for the same period in 2020, an
increase of $3.0 million. The increase was primarily related to a $2.2 million

                                       23

--------------------------------------------------------------------------------
increase in expenses related to subcontractors, consultants and advisors in
connection with continued development of ELX-02 due to the impact of the
COVID-19 pandemic on the corresponding prior year period expense, an increase of
$0.7 million related to operational facilities acquired with Zikani, and a $0.1
million increase in salaries and benefits.

General and administrative expenses



General and administrative expenses were $5.0 million for the three months ended
September 30, 2021, compared to $2.9 million for the same period in 2020, an
increase of $2.2 million. The increase was primarily related to a $0.7 million
increase in stock-based compensation expense, a $0.5 million increase in in
salaries and other personnel related costs related to the merger with Zikani, as
well as an increase of $1.0 million in expenses attributable principally to
infrastructure related costs including legal, accounting and other professional
fees.

General and administrative expenses were $16.7 million for the nine months ended
September 30, 2021, compared to $11.7 million for the same period in 2020, an
increase of $5.0 million. The increase was primarily related to $0.8 million
increase in expenses attributable principally to infrastructure related costs
including legal, accounting and other professional fees, $0.2 million related to
office facilities acquired from Zikani and insurance, and, as further described
below, $4.0 million related to restructuring charges in 2020 that were not
incurred in 2021.

Acquired in-process research and development



Acquired in-process research and development ("IPR&D") expense of $22.7 million
for the nine months ended September 30, 2021 consists of the estimated fair
value of the assets acquired and consideration given in connection with the
acquisition of the Zikani's IPR&D. As the assets acquired were in the research
and development phase and were determined to not have any alternative future
use, such assets were expensed as acquired IPR&D. There was no such expense for
the nine months ended September 30, 2020.

Restructuring charges



Restructuring charges of $4.0 million for the nine months ended September 30,
2020 resulted from the leadership and organizational realignment during the
first quarter of 2020. The total included $1.9 million related to contract
termination and employee separation costs, primarily severance and benefits, and
$2.1 million of stock-based compensation, relating to accelerated vesting of
stock awards. There were no similar charges during the nine months ended
September 30, 2021.

Other expense, net



We recorded $0.4 million in other income, net for the three months ended
September 30, 2021 compared to a $0.3 million other expense, net during the same
period in 2020. We recorded $0.2 million in other expense, net for the nine
months ended September 30, 2021, compared to $0.8 million for the same period in
2020. The increase in the 2021 periods as comparted to the same periods in 2020
was primarily due to the Company recognizing a $0.8 million gain on
extinguishment of debt related to the forgiveness of the PPP loan (defined
below), offset by a $0.3 million loss on extinguishment of debt related to the
repayment of the amounts outstanding under our existing term loan from SVB in
September 2021.

Liquidity and Capital Resources



Liquidity is the ability of a company to generate funds to support its current
and future operations, satisfy its obligations, and otherwise operate on an
ongoing basis. Significant factors in the management of liquidity are funds
generated by operations, levels of accounts receivable and accounts payable and
capital expenditures. We have not generated revenue from sales of any product or
service.

 We have incurred significant operating losses to date and have not generated
revenue from sales of any products or services. Our net losses were $54.6
million and $28.5 million for the nine months ended September 30, 2021, and
2020. As of September 30, 2021, we had an accumulated deficit of $226.2 million.
We have financed our operations primarily through the issuance of equity
instruments, and to a lesser extent, from loans and grants. We have devoted
substantially all of our financial resources and efforts to the development of
our product candidates. We expect that it may be several years, if ever, before
we receive regulatory approval and have a product candidate ready for
commercialization. We expect to continue to incur significant expenses and
operating losses for the foreseeable future. A successful transition to
profitable operations is dependent upon achieving a level of revenue adequate to
support our cost structure. Our net losses may fluctuate significantly from
quarter to quarter and year to year. We anticipate that our expenses may
increase if, and as, we:

                                       24

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

• advance ELX-02 and/or other product candidates further into clinical

development;

• experience any additional delays in enrollment and completion of our

clinical trials due to the COVID-19 pandemic;

• continue the preclinical development of our research programs and advance

candidates into clinical trials;

• pursue regulatory authorization to conduct clinical trials of additional


       product candidates;


  • seek marketing approvals for our product candidates;


    •  establish a sales, marketing and distribution infrastructure to
       commercialize any product candidates for which we obtain marketing
       approval;


  • maintain, expand and protect our intellectual property portfolio;

• hire additional clinical, regulatory, management and scientific personnel;

• add operational, financial and management information systems and personnel;




  • acquire or in-license other product candidates and technologies; and


  • operate as a public company.


We may never achieve profitability and until we do, we will continue to need to
raise additional cash to fund our operations. Our cash and cash equivalents are
highly liquid investments with original maturities of one year or less at the
date of purchase and consist of cash in operating accounts and secured
investments, primarily money market funds.

We believe that our cash and cash equivalents of $52.4 million at September 30,
2021, will enable us to meet anticipated cash needs required to maintain our
current and planned operations through at least the next 12 months from the
issuance of this Report.

Management intends to fund future operations through private or public debt or
equity financing transactions and may seek additional capital through
arrangements with strategic partners or from other sources. If we are unable to
obtain adequate financing, we will evaluate alternatives which may include
reducing or deferring operating expenses, including by downsizing our workforce
and curtailing certain development programs, which could have a material adverse
effect on our operations and future prospects.

Principal Financing Activities



In April 2020, we entered into a loan agreement with SVB under the U.S. Small
Business Administration (the "SBA") Paycheck Protection Program (the "PPP")
pursuant to the Coronavirus Aid, Relief and Economic Security Act of 2020 (the
"CARES Act") and received loan proceeds of $0.8 million (the "PPP Loan"). We
used the loan proceeds for payroll and other covered costs in accordance with
the relevant terms and conditions of the CARES Act. The PPP Loan has an interest
rate of 1.0% per annum. Under the terms of the PPP, on September 3, 2021, the
PPP Loan was forgiven in full and the Company recognized a gain on
extinguishment of debt of $0.8 million during the three and nine months ended
September 30, 2021.

On May 13, 2021, we completed an underwritten public offering of 38,333,334 shares of common stock at a price of $1.35 per share and received gross proceeds of approximately $51.8 million, before deducting underwriting discounts and commissions of $3.1 million and offering expenses of $0.8 million.





On September 30, 2021, we entered into a Loan and Security Agreement with
Hercules Capital, Inc., ("Hercules" or the "Lender"), Hercules agreed to extend
term loans (the "Hercules Term Loan") to the Company in an aggregate principal
amount of up to $30.0 million, comprised of three tranches. The Company drew on
the first tranche of $12.5 million on September 30, 2021 and used $7.7 million
of the proceeds to repay the SVB loan principal, final payment, and early
termination fees, resulting in net proceeds to us of $4.2 million, net of
issuance related costs of $0.6 million. The remaining tranches totaling $17.5
million will be available to the Company based on achieving certain clinical and
equity milestones during defined time periods. We will pay interest only on the
outstanding principal on a monthly basis for the first 18 months of the
agreement, which may be extended for an additional 12 months upon the
achievement of certain milestones. Any amounts outstanding under the term loan
advances, if not repaid sooner, are due and payable on April 1, 2025. On any
date

                                       25

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

that we partially repay the outstanding obligations, the Company shall pay the Lenders a charge equal to 6.55% of the original principal amount.





On September 30, 2021, the Company entered into a Sales Agreement with SVB
Leerink, LLC ("SVB Leerink") pursuant to which the Company may offer and sell up
to $50.0 million of shares of its common stock (the "ATM Shares") from time to
time, through an "at the market offering" program (the "ATM Program"), under
which SVB Leerink will act as sales agent. Pursuant to the Sales Agreement, the
Company will set the parameters for the sale of ATM Shares, including the number
of ATM Shares to be issued, the time period during which sales are requested to
be made, limitations on the number of ATM Shares that may be sold in any one
trading day and any minimum price below which sales may not be made. The Company
is not obligated to make any sales of Shares under the ATM Program. This ATM
Program was not active as of September 30, 2021, and the Company had not sold
any shares under the ATM Program as of such date.

Cash Flows

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

Our operating activities used cash of $25.1 million and $23.5 million during the
nine months ended September 30, 2021 and 2020, respectively. For the nine months
ended September 30, 2021, net cash used in operating activities resulted
primarily from our net loss of $54.6 million, partially offset by total non-cash
charges of $31.5 million. Non-cash charges primarily related to $22.7 million of
acquired in-process research and development, $7.6 million of stock-based
compensation, $0.7 million of amortization of lease assets, and $0.3 million of
debt discount amortization. Changes in working capital were primarily related to
decreases of $0.6 million in prepaid expenses, $0.7 million in operating lease
liabilities, $0.2 million net of accounts payable and accrued expenses, and $1.0
million of merger related costs. For the nine months ended September 30, 2020,
net cash used in operating activities resulted primarily from our net loss of
$28.5 million and total changes in working capital of $3.4 million partially
offset by total non-cash charges of $8.3 million. Non-cash charges primarily
related to $7.4 million of stock-based compensation, $0.5 million of
amortization of lease assets, and $0.4 million of debt discount amortization.
Changes in working capital were primarily related to increases of $1.7 million
in accrued expenses, $1.2 million in accounts payable, $0.4 million in operating
lease liabilities, and in increase of $0.1 million in prepaid expenses and other
current assets.



Our investing activities provided cash of $2.1 million and $33.8 million during
the nine months ended September 30, 2021 and 2020, respectively. For the nine
months ended September 30, 2021, cash provided in investing activities was
primarily related to $2.1 million of cash acquired as part of the merger. For
the nine months ended September 30, 2020, cash provided in investing activities
was primarily related to $33.8 million of proceeds from the maturity of
marketable securities.



Our financing activities provided cash of $50.9 million during the nine months
ended September 30, 2021 and used cash of $2.2 million during the nine months
ended September 30, 2020. For the nine months ended September 30, 2021, net cash
provided by financing activities consisted primarily of net proceeds of $47.7
million from our public offering of common stock in May 2021, $2.9 million in
advances received from collaboration partners, $11.9 million of net cash
received from the Hercules term loan, offset by $11.3 million in SVB term loan
principal and repayments and final loan payment, and $0.2 million related to the
settlement of taxes upon vesting of restricted stock units. For the nine months
ended September 30, 2020, net cash used in financing activities consisted
primarily of $3.3 million in term loan principal repayments, offset by $0.8
million received from the PPP Loan and $0.4 million in advances received from
collaboration partners.

Off-balance Sheet Arrangements



We do not have any off-balance sheet arrangements, as defined by applicable
regulations of the SEC, that are reasonably likely to have a current or future
material effect on our financial condition, results of operations, liquidity,
capital expenditures or capital resources.

Critical Accounting Policies and Use of Estimates



Our management's discussion and analysis of financial condition and results of
operations is based on our unaudited condensed consolidated financial
statements, which have been prepared in accordance with accounting principles
generally accepted in the United States, or U.S. GAAP. The preparation of these
condensed consolidated financial statements requires us to make estimates and
assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the date of the condensed
consolidated financial statements, as well as the reported expense during the
reporting periods. We monitor and analyze these items for changes in facts and
circumstances, and material changes in these estimates could occur in the
future. We base our estimates on historical experience 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.

The critical accounting policies that we believe impact significant judgments
and estimates used in the preparation of our condensed consolidated financial
statements presented in this Report are described in "Management's Discussion
and Analysis of Financial Condition and Results of Operations" in our Annual
Report. There have been no material changes to our critical accounting policies
through September 30, 2021 from those discussed in our Annual Report filed with
the SEC on March 12, 2021.
