Overview

We are a clinical-stage biopharmaceutical company focused on the development of GP2, an immunotherapy to prevent breast cancer recurrences in patients who have previously undergone surgery. GP2 is a 9 amino acid transmembrane peptide of the HER2/neu protein, a cell surface receptor protein that is expressed in a variety of common cancers, including expression in 75% of breast cancers at low (1+), intermediate (2+), and high (3+ or over-expressor) levels. The combination of GP2 + GM-CSF is called GLSI-100. In a completed randomized, single-blinded, placebo-controlled, multi-center Phase IIb clinical trial led by MD Anderson Cancer Center, no recurrences were observed in patients treated with GLSI-100 in the HER2/neu 3+ adjuvant setting after median 5 years of follow-up, if the patients were treated, followed, and remained disease free over the first 6 months, which is the time required to reach peak immunity and thus maximum efficacy and protection (p = 0.0338). For the 146 patients who have been treated with GLSI-100 to date over 4 clinical trials, treatment was well tolerated and no serious adverse events were observed related to the immunotherapy. We have commenced Flamingo-01, a Phase III clinical trial with Baylor College of Medicine as the global primary investigator site. Flamingo-01 is designed to evaluate the safety and efficacy of GLSI-100 in HER2/neu positive patients with residual disease or high-risk pathologic complete response at surgery and who have completed both neoadjuvant and postoperative adjuvant trastuzumab based treatment.

To date, we have not generated any revenue and we have incurred net losses. Our net losses were approximately $7.8 million and $4.6 million for the years ended December 31, 2022 and 2021, respectively.

Our net losses have resulted from costs incurred in developing the drug in our pipeline, planning and preparing for clinical trials and general and administrative activities associated with our operations. We expect to continue to incur significant expenses and corresponding increased operating losses for the foreseeable future as we continue to develop our pipeline. Our costs may further increase as we conduct clinical trials and seek regulatory approval for and prepare to commercialize our product candidate. We expect to incur significant expenses to continue to build the infrastructure necessary to support our expanded operations, clinical trials, commercialization, including manufacturing, marketing, sales and distribution functions. We will also experience increased costs associated with operating as a public company.

Basis of Presentation


The accompanying financial statements are presented in conformity with accounting principles generally accepted in the U.S. ("GAAP") and pursuant to the rules and regulations of the SEC.

Results of Operations For the Years Ended December 31, 2022 and 2021

Research and Development Expenses

Research and development expenses increased by $2,916,153, or approximately 82%, to $6,475,668 for the year ended December 31, 2022 from $3,559,515 for the year ended December 31, 2021. The increase was primarily the result of increases in manufacturing and clinical expenses for the Phase III clinical trial.

General and Administrative Expenses

General and administrative expenses increased by $526,158, or approximately 51% to $1,564,586 for the year ended December 31, 2022 from $1,038,428 for the year ended December 31, 2021. The increase was primarily the result of increases in cash and stock-based compensation expense.

Liquidity and Capital Resources

Since our inception in 2006, we have devoted most of our cash resources to research and development and general and administrative activities. We have not yet achieved commercialization of our product and have a cumulative net loss from our operations. We will continue to incur net losses for the foreseeable future.

We will require additional capital to meet our long-term operating requirements. We expect to raise additional capital through the sale of equity and/or debt securities; however, there is no assurance that we will be successful at raising additional capital in the future. If our plans are not achieved and/or if significant unanticipated events occur, we may have to further modify our business plan, which may require us to raise additional capital. As of December 31, 2022 and December 31, 2021, our principal source of liquidity was our cash, which totaled $13,468,026 and $27,204,269, respectively, and additional loans and accrued unreimbursed expenses from related parties. Historically, our principal sources of cash have included proceeds from the sale of common stock and preferred stock and related party loans. Our principal uses of cash have included cash used in operations. We expect that the principal uses of cash in the future will be for continuing operations, funding of research and development, including our clinical trials, and general working capital requirements.

Cash Flow Activities for the Years Ended December 31, 2022 and 2021

We incurred net losses of $7,825,237 and $4,570,576 during the years ended December 31, 2022 and 2021, respectively, and the increase was primarily the result of increases in manufacturing and clinical expenses for the Phase III clinical trial and increases in cash and stock-based compensation expense. Cash was $13,468,026 at December 31, 2022 and $27,204,269 at December 31, 2021 and decreased due to the following reasons:





Operating Activities


Net cash used in operating activities was $6,200,027 for the year ended December 31, 2022 and $4,291,548 for the year ended December 31, 2021. The increase was primarily the result of increases in manufacturing and clinical expenses for the Phase III clinical trial and increases in cash compensation expense.





Investing Activities


We did not use or generate cash from investing activities during the year ended December 31, 2022 and December 31, 2021.





Financing Activities


Net cash used in financing activities was $7,536,216 during the year ended December 31, 2022, attributable to the repurchase of common stock pursuant to the Company's stock repurchase program. Net cash provided by financing activities was $2,835,442 during the year ended December 31, 2021, attributable to the exercise of the underwriter's over-allotment option from our follow-on offering and the partial exercise of underwriter warrants.

Contractual Obligations and Commitments

As of December 31, 2022, we did not have any material contractual obligations, other than employment and shareholder agreements, license for GP2 from HJF, manufacturing and clinical trial obligations related to the Phase III clinical trial.

Off-Balance Sheet Arrangements

As of December 31, 2022, we did not have any off-balance sheet arrangements as described by Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies and Estimates

Our financial statements are prepared in conformity with U.S. GAAP, which require the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of expenses in the periods presented.

On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses and stock-based compensation. 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 and the reported amounts of expenses that are not readily apparent from other sources. Actual results could differ from those estimates, particularly given the significant social and economic disruptions and uncertainties associated with the ongoing coronavirus pandemic and the COVID-19 control responses.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which provides guidance requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for substantially all leases, with the exception of short-term leases. Leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the statement of income. The Company adopted Topic 842 effective October 1, 2019 and elected the package of transition practical expedients for expired or existing contracts, which does not require reassessment of: (1) whether any of the Company's contracts are or contain leases, (2) lease classification and (3) initial direct costs. In July 2018, the FASB issued ASU No. 2018-11, "Targeted Improvements - Leases (Topic 842)." The Company did not elect the hindsight practical expedient. This update provides an optional transition method that allows entities to elect to apply the standard using the modified retrospective approach at its effective date, versus recasting the prior years presented. If this adoption method is elected, an entity would recognize a cumulative-effect adjustment to the opening balance of retained earnings in the year of adoption. The Company elected this adoption method on October 1, 2019 and the adoption did not result in any cumulative impact to retained earnings.

Additionally, the Company's adoption of Topic 842 did not have a significant impact on the recognition, measurement, or presentation of lease expenses within the statements of operations or the statements of cash flows. The Company's adoption of Topic 842 did not have a material impact on the timing or amount of the Company's sublease agreement.

In January 2021, the Company early adopted ASU 2020-06 Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40). ASU 2020-06 simplifies the accounting for convertible debt instruments and convertible preferred stock by reducing the number of accounting models and limiting the number of embedded conversion features separately recognized from the primary contract. The guidance also includes targeted improvements to the disclosures for convertible instruments and earnings per share. ASU 2020-06 is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The adoption of ASU 2020-06 did not have a material impact on the Company's financial statements.





JOBS Act


On April 5, 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an "emerging growth company" can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended ("Securities Act") for complying with new or revised accounting standards. In other words, an "emerging growth company" can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies.

We have chosen to take advantage of the extended transition periods available to emerging growth companies under the JOBS Act for complying with new or revised accounting standards until those standards would otherwise apply to private companies provided under the JOBS Act. As a result, our financial statements may not be comparable to those of companies that comply with public company effective dates for complying with new or revised accounting standards.

Subject to certain conditions set forth in the JOBS Act, as an "emerging growth company," we intend to rely on certain of these exemptions, including, without limitation, (i) providing an auditor's attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (ii) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board ("PCAOB") regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an "emerging growth company" until the earliest of (i) the last day of the fiscal year in which we have total annual gross revenues of $1.07 billion or more; (ii) the last day of our fiscal year following the fifth anniversary of the date of the completion of our initial public offering; (iii) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.
