We are a clinical stage biotechnology company leveraging the power of the mitochondria and the peptides encoded in its genome to develop potential breakthrough therapeutics targeting chronic and age-related diseases. Our novel approach is built on the key insights of our founders that certain mitochondrially encoded peptides produce effects that are not limited to local regulation within the mitochondria and may have important roles to play in critical systemic biological pathways. Many of these effects are quite distinct from what has traditionally been thought of as mitochondrial function.

Through our exploration of the mitochondrial genome and its utility for the development of novel therapeutics, we have developed a world-renowned expertise in mitochondrial biology and a broad intellectual property estate with 6 issued patents and approximately 30 pending patent applications. Our proprietary processes of identifying nucleic acid sequences encoding native peptides in the mitochondrial genome, developing and optimizing novel analogs of these natural mitochondrial derived peptides ("MDPs"), as well as developing and conducting proprietary screens to identify and characterize the activities of these peptides are referred to as our technology platform. We are exploring development and/or partnership opportunities within the Company's peptide library and technology platform.

Historically, we have financed our operations primarily with proceeds from sales of our equity securities, including our initial public offering, private placements of our securities, a debt offering, public sales of our securities and the exercise of outstanding warrants and stock options. Since our inception through December 31, 2022, our operations have been funded with an aggregate of approximately $97.3 million from the sale and issuance of equity instruments and debt, including the proceeds from the exercise of warrants and stock options.

Since inception, we have incurred significant operating losses. Our net losses were $12.2 million and $15.5 million for the years ended December 31, 2022 and 2021, respectively. We incurred $1.8 million and $2.7 million in non-cash expenses during the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022, we had an accumulated deficit of $96.9 million. Dependent upon our ultimate determination of whether or not to pursue any potential strategic alternative selected by the Company, significant expenses and operating losses over the next several years may continue to occur. Our net losses may fluctuate significantly from quarter to quarter and from year to year.





Recent Developments



We have retained Ladenburg Thalmann & Co. Inc. as a financial advisor to assist the Company in exploring strategic alternatives. Potential strategic alternatives that may be explored or evaluated as part of this process include a merger, business combination, investment into the Company, asset sale or other strategic transaction. Our board of directors has not set a timetable for the conclusion of this review, nor has it made any definitive decisions related to taking any further actions or potential strategic options at this time or at all. There can be no assurance that this process will result in any such transaction and the Company does not intend to disclose additional details unless and until it has entered into a specific transaction.

Financial Operations Review



Revenue


To date, we have not generated any revenue from product sales and do not expect to generate any revenue from the sale of products in the near future.





                                       32




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;



? expenses incurred under agreements with third parties, including CROs that

conduct research and development and preclinical activities on our behalf and


   the cost of consultants;



? the cost of laboratory equipment, supplies and manufacturing test materials;


   and



? depreciation and other personnel-related costs associated with research and


   product development.



We record all research and development expenses as incurred.





Our Research Programs


Our research and development programs have historically included activities in support of the clinical development of our most advanced program, CB4211, as well as the operation of our platform technology related to the discovery and development of novel therapeutics, evaluation of newly discovered natural sequences, design of novel improved analogs, evaluation of their therapeutic potential and optimization of their characteristics as potential drug development candidates. Depending on factors of capability, cost, efficiency and intellectual property rights, we have conducted our research programs at our laboratory facility, or externally, pursuant to contractual arrangements with CROs or under collaborative arrangements with academic institutions.

The success of our research programs and the timing of those programs and the possible development of research peptides into drug candidates is highly uncertain. As such, at this time, we cannot reasonably estimate or know the nature, timing or estimated costs of the efforts that will be necessary to complete research and development of a commercial drug. We are also unable to predict when, if ever, we will receive material net cash inflows from our operations. This is due to the numerous risks and uncertainties associated with developing medicines, including the uncertainty of:

? developing appropriate manufacturing processes and formulations;

? establishing an appropriate safety profile with toxicology studies;

? obtaining appropriate regulatory approval for conducting clinical trials;

? successfully designing, enrolling and completing clinical trials;

? receiving marketing approvals from applicable regulatory authorities;

? establishing commercial manufacturing capabilities or making arrangements with


   third-party manufacturers;



? obtaining and enforcing patent and trade secret protection for our product


   candidates;



? launching commercial sales of the products, if and when approved, whether alone

or in collaboration with others; and

? maintaining an acceptable safety profile of the products following approval.

A change in the outcome of any of these variables with respect to the development of any of our product candidates would significantly change the costs and timing associated with the development of that product candidate.





                                       33




Research and development activities have historically been central to our business model and have primarily focused on potential drug candidates in early stages of investigational research. Candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. We expect research and development costs to decrease in the next several quarters due to the recent suspension of our CB5138-3 program and as we evaluate potential strategic alternatives. As such, we do not believe that it is possible at this time to accurately project our research and development costs. There are numerous factors associated with the successful commercialization of a product candidate, including future trial design, various regulatory requirements and future commercial and regulatory factors beyond our control, many of which cannot be determined with accuracy at this time.

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 and administrative functions. Other significant costs include legal fees relating to patent and corporate matters and fees for accounting and consulting services and directors' and officers' insurance. We anticipate that our general and administrative expenses will increase in the year ending December 31, 2023, including with respect to costs associated with our evaluation of potential strategic alternatives.





Results of Operations


The following tables set forth our results of operations for the periods presented. The year-to-year comparison of financial results is not necessarily indicative of financial results to be achieved in future periods, particularly in light of our decisions to suspend IND-enabling work on pre-clinical candidate CB5138-3 and to explore strategic alternatives.

Comparison of Fiscal Years Ended December 31, 2022 and 2021





Operating Expenses


Research and development expenses were $5.9 million in the year ended December 31, 2022 compared to $7.7 million in the prior year, a $1.8 million or 23% decrease. The decrease in research and development expenses in the year ended December 31, 2022, was primarily due to a decrease of $1.0 million in clinical trial related costs due to the conclusion of the trial and the timing of those expenses and a decrease of approximately $0.8 million associated with our research programs focused on continuing the development of our peptides.

General and administrative expenses were $6.5 million in the year ended December 31, 2022 compared to $7.7 million in the prior year, a $1.3 million or 16% decrease. The decrease in general and administrative expenses was due to lower compensation costs of approximately $1.1 million primarily related to lower stock-based compensation costs of $0.7 million due to the amount recognized in the prior year related to the departure of our former CEO and $0.4 million in one-time charges incurred in the previous year related to the departure of our former CEO.

Liquidity and Capital Resources

As of December 31, 2022, we had $15.7 million in cash, cash equivalents and investments. As of December 31, 2021, we had $26.2 million in cash and cash equivalents. We maintain our cash in a checking and a savings account on deposit with a banking institution in the United States. Our cash equivalent balance as of December 31, 2022 and 2021 included $3.9 million and $0.7 million, respectively, of U.S. Treasury Bills that had maturity dates of less than three months at the date of purchase. As of December 31, 2022, we had working capital and stockholders' equity of $15.2 million and $15.3 million, respectively, and we incurred a net loss of $12.2 million for the year ended December 31, 2022.





                                       34




In November 2021, we completed an underwritten public offering of our securities (the "2021 Public Offering") pursuant to which we sold 20.8 million shares of our common stock and warrants to purchase 0.7 million shares of common stock for proceeds of $13.8 million, net of commissions and professional fees of approximately $1.2 million. The warrants issued in the 2021 Public Offering were immediately exercisable and have a term of five years and a per share exercise price of $21.60.

On May 27, 2020, we entered into an At-the-Market Offering Sales Agreement ("ATM") with Virtu Americas, LLC, as sales agent, pursuant to which we may sell shares of common stock with an aggregate offering price of up to $20 million. During the year ended December 31, 2022, we sold 23.4 thousand shares of our common stock under the ATM program for proceeds of $0.2 million, net of commissions. During the year ended December 31, 2021, we sold 55.2 thousand shares of our common stock under the ATM program for proceeds of $2.9 million, net of commissions and incurred professional fees of approximately $21,000. As of December 31, 2022, we had $5.0 million available in our ATM program but are limited in the amount we can utilize due to restrictions under the "baby shelf rule" limitations of our Registration Statement on Form S-3 filed with the SEC on January 22, 2021 Baby Shelf Rules.

As reflected in the financial statements, we had an accumulated deficit as of December 31, 2022 and 2021, as well as recurring losses and negative cash flows from operating activities from inception. These factors raised substantial doubt about our ability to continue as a going concern for at least one year from the issuance of these financial statements. However, based on current budget assumptions, projected cash burn and our latitude to manage that cash burn, the cash and investments on hand as of December 31, 2022 and a planned decrease in our research and development expenses due to the suspension of the IND-enabling work for pre-clinical candidate CB5138-3 and a focus on evaluating potential strategic alternatives, we believe that we have sufficient capital to meet our operating expenses and obligations for the next twelve months from the date of this filing. However, if unanticipated difficulties or circumstances arise and, depending on the ultimate outcome of our evaluation of strategic alternatives, we may require additional capital sooner to support our operations. If we are unable to raise additional capital whenever necessary, we may be forced to further decelerate or curtail our operations until such time as additional capital becomes available, which could have a material adverse effect on the Company and its financial statements. There can be no assurance that such a plan would be successful. There is no assurance that additional financing will be available when needed or that we will be able to obtain such financing on reasonable terms.

Cash Flows from Operating Activities

Net cash used in operating activities for the years ended December 31, 2022 and 2021 was $10.4 million and $14.4 million, respectively. Cash used in operating activities for the year ended December 31, 2022 primarily reflected our net loss of $12.2 million, which was partially offset by $1.7 million in stock based-compensation expenses. Cash used in operating activities for the year ended December 31, 2021 primarily reflected our net loss of $15.5 million and a $0.9 million decrease in accrued liabilities due to the timing of those expenses partially offset by $2.5 million of stock based-compensation.

Cash Flows from Investing Activities

Net cash provided by investing activities for the year ended December 31, 2022 was $11.5 million and net cash used in investing activities for the year ended December 31, 2021 was $3.1 million. The net cash provided by investing activities for the year ended December 31, 2022 primarily reflected the timing of the purchases and maturities of our investments. The cash used in investing activities for the year ended December 31, 2021 primarily reflected the timing of the purchases and maturities of our investments.





                                       35




Cash Flows from Financing Activities

Net cash used in financing activities for the year ended December 31, 2022 was $0.1 million, and primarily reflected the repayment of a promissory note having a principal balance of $0.4 million, which was partially offset by proceeds from the Company's ATM and ESPP programs, which totaled $0.2 million. Net cash provided by financing activities for the year ended December 31, 2021 was $19.7 million, and primarily reflected net proceeds of $13.8 million from our underwritten public offering, $2.9 million from our ATM program, $2.1 million from the exercise of warrants and $1.2 million from the exercise of employee stock options.





Operating Leases



We are a party to a lease agreement for laboratory space leased on a month-to month basis that is part of a shared facility in Menlo Park, California. In September 2022, we renewed our lease for office space in Fairfield, New Jersey for an additional year at the same annual cost of $13,080 per annum.

Rent expense amounted to $0.4 million in each of the years ended December 31, 2022 and 2021.

Recent Accounting Pronouncements

See Note 3 "Summary of Significant Account Policies - Recent Accounting Pronouncements" to our Financial Statements for the year ended December 31, 2022, for a summary of the relevant recent accounting pronouncements.

Other recent accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company's financial statements upon adoption.

Critical Accounting Estimates

Our management's discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). U.S. GAAP requires us to make certain estimates and judgments that can affect the reported amounts of assets and liabilities as of the dates of the financial statements, the disclosure of contingencies as of the dates of the financial statements, and the reported amounts of revenue and expenses during the periods presented. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. If actual results or events differ materially from those contemplated by us in making these estimates, our reported financial condition and results of operations for future periods could be materially affected. See the section entitled "Risk Factors" above for certain matters that may affect our future financial condition or results of operations. An accounting policy is deemed to be critical if it requires an accounting estimate to be made based on assumptions about matters that are uncertain at the time the estimate is made, if different estimates reasonably could have been used, or if the changes in the estimate that are reasonably likely to occur could materially impact the financial statements. Our management has discussed the development, selection and disclosure of these estimates with the audit committee of our board of directors.

The following critical accounting estimates reflect significant judgments and estimates used in the preparation of our financial statements:

? fair value of financial instruments;






 ? going concern analysis;




 ? share-based payments; and



? valuation of deferred tax assets






                                       36




Fair Value of Financial Instruments

We measure the fair value of financial assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We utilize three levels of inputs that may be used to measure fair value:

? Level 1 - quoted prices in active markets for identical assets or liabilities.

? Level 2 - quoted prices for similar assets and liabilities in active markets or

inputs that are observable.

? Level 3 - inputs that are unobservable (for example, cash flow modeling inputs


   based on assumptions).



The carrying amounts of cash, accounts payable, accrued liabilities and debt approximate fair value due to the short-term nature of these instruments.





Share-based Payments


We account for share-based payments using the fair value method. For employees and directors, the fair value of the award is measured on the grant date. For non-employees, fair value is generally measured based on the fair value of the services provided or the fair value of the common stock on the measurement date, whichever is more readily determinable. We have historically granted stock options at exercise prices no less than the fair market value as determined by the board of directors, with input from management.

See Note 3 "Summary of Significant Account Policies - Share-Based Payments" to our Financial Statements for the years ended December 31, 2022 and 2021 for the specific assumptions used with respect to stock-based compensation for the periods presented.

Valuation of Deferred Tax Assets

We recognize deferred tax assets and liabilities for the expected future tax consequences of items that have been included or excluded in the financial statements or tax returns. Deferred tax assets and liabilities are determined on the basis of the difference between the tax basis of assets and liabilities and their respective financial reporting amounts ("temporary differences") at enacted tax rates in effect for the years in which the temporary differences are expected to reverse.

The benefit of tax positions taken or expected to be taken in income tax returns are recognized in the financial statements if such positions are more likely than not of being sustained. We have evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company's financial statements as of December 31, 2022 and 2021. The Company does not expect any significant changes in the unrecognized tax benefits within twelve months of the reporting date.
