Company Overview



We are a clinical-stage biopharmaceutical company engaged in the science of
ribosome modulation, leveraging both its 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 in the fourth quarter 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.

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 Ribosome Modulating Agents (RMAs) as potential therapeutics for
people 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 Eukaryotic Ribosome Selective Glycosides (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 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 EB, 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

                                       22

--------------------------------------------------------------------------------
disease frequently caused by nonsense mutations in the 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 percent 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. 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 $5.7 million for the three months ended
June 30, 2021, compared to $3.7 million for the same period in 2020, an increase
of $2.0 million. The increase was primarily related to a $1.8 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 $0.3 million partially offset by a $0.1 million
decrease in stock-based compensation expense.

                                       23

--------------------------------------------------------------------------------
Research and development expenses were $9.8 million for the six months ended
June 30, 2021 compared to $8.5 million for the same period in 2020, an increase
of $1.3 million. The increase was primarily related to a $1.50 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, partially offset by a decrease
in salaries and other personnel related costs of $0.1 million, and a $0.1
million decrease in stock-based compensation expense.



General and administrative expenses



General and administrative expenses were $7.4 million for the three months ended
June 30, 2021, compared to $3.8 million for the same period in 2020, an increase
of $3.5 million. The increase was primarily related to a $2.2 million increase
in stock-based compensation expense, a $1.2 million increase in in salaries and
other personnel related costs related to the merger with Zikani, as well as an
increase of $0.1 million increase in expenses attributable principally to
infrastructure related costs including legal, accounting and other professional
fees.

General and administrative expenses were $11.7 million for the six months ended
June 30, 2021, compared to $8.9 million for the same period in 2020, an increase
of $2.8 million. The increase was primarily related to a $1.6 million increase
in stock-based compensation expense, a $1.0 million increase in in salaries and
other personnel related costs related to the merger with Zikani, as well as an
increase of $0.2 million increase in expenses attributable principally to
infrastructure related costs including legal, accounting and other professional
fees.

Acquired in-process research and development



Acquired in-process research and development ("IPR&D") expense of $22.7 million
for the six months ended June 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, it
was expensed as acquired IPR&D. There was no such expense for the six months
ended June 30, 2020.

Restructuring charges

Restructuring charges of $4.0 million for the six months ended June 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 six months ended June 30, 2021.

Other expense, net



We recorded $0.3 million in other expense, net for each of the three months
ended June 30, 2021, and 2020. We recorded $0.6 million in other expense, net
for the six months ended June 30, 2021, compared to $0.5 million for the same
period in 2020. The increase in other expense, net was primarily due to lower
interest income.

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 $44.8
million and $7.9 million for the six months ended June 30, 2021, and 2020. As of
June 30, 2021, we had an accumulated deficit of $216.3 million. Further, we
expect to incur additional costs related to our acquisition of Zikani. 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

                                       24

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

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:

• 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 $56.7 million at June 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 Silicon Valley Bank ("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 a maturity date of April 21, 2022 and an interest rate of
1.0% per annum. Monthly payments of principal and interest are due beginning on
September 21, 2021, although interest accrues from the issuance date. A PPP loan
may be partially or entirely forgiven based on employee retention for the
24-week period starting on the loan date through October 2020, and the use of
loan proceeds for payroll or other specified costs during the same
period. Forgiveness is also based on the employer maintaining or restoring
headcount and maintaining salary levels. Forgiveness is reduced if headcount
declines or if salaries decrease. Any loan forgiveness will be made subject to
SVB approval in accordance with SBA requirements.

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.

Net cash provided by (used in) financing activities 47,593 (939 )






Our operating activities used cash of $17.5 million and $18.2 million during the
six months ended June 30, 2021 and 2020, respectively. For the six months ended
June 30, 2021, net cash used in operating activities resulted primarily from our
net loss of $44.8 million and changes in working capital of $0.3 million,
partially offset by total non-cash charges of $28.5 million. Non-cash charges
primarily related to $22.7 million of acquired in-process research and
development, $5.3 million of stock-based compensation, $0.3 million of
amortization of lease assets, and $0.2 million of debt discount amortization.
Changes in working capital were primarily related to decreases of $0.1 million
in prepaid expenses, $0.2 million in operating lease liabilities, and $1.0
million of merger related costs. For the six months ended June 30, 2020, net
cash used in operating activities resulted primarily from our net loss of
$(21.8) million and total changes in working capital of $(3.0) million partially
offset by total non-cash charges of $6.6 million. Non-cash charges primarily
related to $6.0 million of stock-based compensation, $0.3 million of
amortization of lease assets, and $0.3 million of debt discount amortization.
Changes in working capital were primarily related to decreases of $1.2 million
in accrued expenses, $1.1 million in accounts payable and $0.3 million in
operating lease liabilities, and in increase of $0.4 million in prepaid expenses
and other current assets.



Our investing activities provided cash of $2.1 million and $27.0 million during
the six months ended June 30, 2021 and 2020, respectively.  For the six months
ended June 30, 2021, cash provided in investing activities was primarily related
to $2.1 million of cash acquired as part of the merger. For the six months ended
June 30, 2020, cash provided in investing activities was primarily related to
$27.0 million of proceeds from the maturity of marketable securities.



Our financing activities provided cash of $47.6 million during the six months
ended June 30, 2021 and used cash of $0.9 million during the six months ended
June 30, 2020. For the six months ended June 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, $2.6 million in advances
received from collaboration partners, offset by $2.5 million in term loan
principal repayments and $0.2 million related to the settlement of taxes upon
vesting of restricted stock units. For the six months ended June 30, 2020, net
cash used in financing activities consisted primarily of $2.1 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.

                                       26

--------------------------------------------------------------------------------
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 June 30, 2021 from those discussed in our Annual Report filed with the
SEC on March 12, 2021.
