You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and related notes thereto included in Part I-Item 1 of this Form 10-Q. This discussion and other parts of this report contain forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions that are based on the beliefs of our management, as well as assumptions made by, and information currently available to, our management.

Overview

We are a late-stage clinical specialty pharmaceutical company focused on the development and commercialization of therapeutic products that treat rare and orphan diseases for which there are currently either no approved or very limited treatments or cures. Our lead product, QRX003, is in late-stage clinical development as a potential treatment for Netherton Syndrome, a rare hereditary genetic disease. QRX003 is currently being tested in three regulatory clinical studies under an open IND application with the FDA. We have opened five clinical sites in the US and intend to open a sixth US clinical site at Northwestern University. We are expanding our trials internationally into the Middle East, the United Kingdom and additional countries in Western and Eastern Europe. QRX003 is currently being tested in a pediatric NS patient at the Children’s Hospital in Dublin, Ireland and we intend to expand this study to include additional children with NS in Spain, the United Kingdom and potentially other countries. QRX003 is also being developed as a potential treatment for Peeling Skin Syndrome with the first subject being treated in New Zealand. In addition, we entered into two separate Research Agreements with the Queensland University of Technology, under which we have obtained an option for global licenses to QRX007 for the potential treatment of NS and QRX008 for the potential treatment of scleroderma, as well as a Research Agreement with University College Cork for the development of novel topical formulations of Rapamycin (sirolimus) as potential treatments for a number of rare and orphan diseases for which there are either limited or no approved therapies or cures. Other development products in our pipeline include QRX004 as a potential treatment for Recessive Dystrophic Epidermolysis Bullosa.

Our mission is to develop and commercialize proprietary therapeutic drug products that treat rare and orphan diseases, particularly those where none currently exists. To achieve this, we plan to:

To date, no products have been commercialized and no revenue has been generated. We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain marketing approval for one or more of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. Accordingly, we will need to raise additional capital prior to the commercialization of QRX003 or any other product candidate. Until such time, if ever, as we can generate substantial revenue from product sales, we expect to finance our operating activities through a combination of equity offerings, debt financings, government or other third-party funding, commercialization, marketing and distribution arrangements and other collaborations, strategic alliances and licensing arrangements. However, we may 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 continue our operations. See “Liquidity and Capital Resources”.

Recent Developments

ADS Ratio Change

In order to regain compliance with the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”) we effected a change in the ratio of American Depositary Shares (“ADSs”) evidencing our ordinary shares (“Ordinary Shares”) from one (1) ADS representing one (1) Ordinary Share to one (1) ADS representing thirty-five (35) Ordinary Shares (the “Ratio Change”), which resulted in a 1 for 35 reverse split of the issued and outstanding ADSs (the “Reverse Split”). Our Ordinary Shares were not affected by this adjustment.

Except as specifically provided, ADSs and related option and warrant information presented herein, including our unaudited condensed consolidated financial statements and accompanying footnotes, has been retroactively adjusted to reflect the Ratio Change and the Reverse Split.

Nasdaq Listing

On April 29, 2024, we received a letter from the Listing Qualifications staff Nasdaq notifying us that the closing bid price per ADS was below the required minimum of $1.00 for a period of 30 consecutive business days and that we did not meet the Minimum Bid Price Requirements set forth in Nasdaq Listing Rule 5550(a)(2). Pursuant to Nasdaq Rule 5810(c)(3)(A), we had an initial period of one hundred eighty (180) calendar days, or until October 28, 2024, which was subsequently extended for an additional one hundred eighty (180) calendar days, or until April 28, 2025, to regain compliance with Nasdaq’s Minimum Bid Price Requirement.

On April 29, 2025, we received a notification letter (the “Notification Letter”) from Nasdaq, stating that we had regained compliance with the Minimum Bid Price Requirement set forth in Nasdaq Listing Rule 5550(a)(2). To regain compliance with the Minimum Bid Price Requirement, the closing bid of our ADSs needed to be at least $1.00 per share for a minimum of ten (10) consecutive business days. The Notification Letter confirmed that we had achieved a closing bid price of $1.00 or greater per ADS for thirteen (13) consecutive business days from April 9, 2025 to April 28, 2025, thereby regaining compliance with the Minimum Bid Price Requirement.

There can be no assurance that we will be able to maintain compliance with Nasdaq’s Minimum Bid Price Requirement for continued listing. If our ADSs are delisted from Nasdaq, it will have a material negative impact on the actual and potential liquidity of our securities, as well as a material negative impact on our ability to raise future capital.

Warrant Exercises

In January and February 2025, certain investors in our December 2024 Offering exercised (i) the remaining outstanding 320,362 December 2024 Pre-Funded Warrants, (ii) 9,143 Series F Warrants and 3,000 Series G Warrants, resulting in net proceeds of approximately $173,000.

Components of Our Results of Operations

Operating Expenses

Our current operating expenses consist of two components - research and development expenses, and general and administrative expenses.

Research and Development Expenses

Research and development costs are expensed as incurred. Research and development expenses include personnel costs associated with research and development activities, including third-party contractors to perform research, conduct clinical trials and manufacture drug supplies and materials. We utilize outside consultants and third parties to conduct the majority of our research and development, under the supervision of our management team.

Future research and development expenses may include:

Research and development activities will continue to be central to our business plan. Product 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 our research and development expenses to be significant over the next several years as personnel and compensation costs increase and we conduct late-stage clinical studies and prepare to seek regulatory approval for QRX003 and any other future product candidate.

The duration, costs and timing of clinical trials of QRX003 and any other future product candidate will depend on a variety of factors that include, but are not limited to:

General and Administrative Expenses

General and administrative expenses consist primarily of compensation and employee related expenses including non-cash stock-based compensation, professional fees and other corporate expenses. We anticipate that our general and administrative expenses will increase in the future to support our continued research and development activities. These increases will likely include compensation and employee-related expenses including stock-based compensation, increased costs related to the potential hiring of personnel, travel costs and fees to outside consultants, lawyers and accountants.

Other Expenses (income)

Other expenses (income) consist primarily of interest income and unrealized loss (gain) on investments.

Results of Operations – Three months ended March 31, 2025 compared to the three months ended March 31, 2024

The following table sets forth our results of operations for the three months ended March 31, 2025, compared to the three months ended March 31, 2024:

​

​

General and Administrative Expenses

General and administrative expenses were approximately $1,583,000 and $1,573,000, in the three months ended March 31, 2025 and 2024, respectively, representing an increase of $10,000, or approximately 0.6%. The increase was primarily due to an increase of $108,000 in legal and professional fees and $113,000 in public company costs, offset by, a decrease of $28,000 in insurance costs and a decreases in payroll and benefits of $154,000 and non-cash stock-based compensation expense of $16,000 due to increased allocation of such costs to research and development expenses.

Research and Development Expenses

Our research and development expenses during the three months ended March 31, 2025 and 2024 were approximately $2,374,000 and $885,000, respectively, representing an increase of $1,489,000, or approximately 168.2%. The increase was primarily due to $1,140,000 in increased external expenditures on our development programs, including work related to the clinical studies for the development of QRX003, an increase of payroll and benefits of $147,000 and $70,000 of non-cash stock-based compensation expense allocated to research and development expenses, and $131,000 of increased other research and development expenditures including our research collaboration with University College Cork. See “Components of Our Results of Operations - Research and Development Expenses” above.

We amortize licensed or acquired intellectual property over its expected useful life, included in research and development expenses set out above. Amortization of intangible assets was approximately $25,000 and $25,000 in each of the three month periods ended March 31, 2025 and 2024.

Other Expenses:

We had approximately $145,000 in realized and accrued interest income in the three months ended March 31, 2025 from our cash and cash equivalents and investments in marketable debt securities. We had $6,500 in unrealized loss and $138,000 in realized gain and accrued interest income in the three months ended March 31, 2024 from our cash and cash equivalents and investments in marketable debt securities.

Liquidity and Capital Resources

We have incurred net losses every year since inception and had an accumulated deficit of approximately $59.0 million at March 31, 2025. We have a limited operating history and have historically funded our operations through debt and equity financings. We incurred net losses of approximately $3.8 million and negative cash flows from operations of $2.6 million for the three months ended March 31, 2025. At March 31, 2025, we had cash and cash equivalent balances totaling $3.8 million and investments of $7.7 million. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of planned clinical trials and our expenditures on other research and development activities. Despite our recent financing in December 2024, pursuant to which we raised gross proceeds of approximately $6.8 million, based upon the Company’s current business plans and cash, cash equivalents and investments on hand, management has concluded that there is substantial doubt about our ability to continue as a going concern for a period of at least one year from the issuance of the unaudited consolidated financial statements included in this report. We need to raise further capital through the sale of additional equity or debt securities or other debt instruments, strategic relationships or grants to support our future operations. We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain marketing approval for one or more of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. Additional financing will be required to complete the research and development of our therapeutic targets and our other operating requirements, which may not be available at acceptable terms, if at all. If we are unable to improve our liquidity position, we may not be able to continue as a going concern. Our ability to continue as a going concern is dependent upon our ability to generate revenue and raise capital from financing transactions. There can be no assurance that we will be successful in accomplishing these objectives.

We continue to seek sources of financing to fund our continued operations and research and development programs. To raise additional capital, we may sell additional equity or debt securities, or enter into collaborative, strategic, and/or licensing transactions. There can be no assurance that we will be able to complete any financing transaction in a timely manner or on acceptable terms or otherwise enter into a collaborative or strategic transaction. If we are unable to obtain additional funding when it becomes necessary, the development of our product candidates will be impacted and we would likely be forced to delay, reduce, or terminate some or all of our development programs or cease operations altogether, all of which could have a material adverse effect on our business, results of operations and financial condition.

Future Funding Requirements

We will need to obtain further funding through public or private offerings of our capital stock, debt financing, collaboration and licensing arrangements or other sources, the requirements for which will depend on many factors, including:

Adequate additional funding may not be available to us on acceptable terms, or at all. If we are unable to raise capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of QRX003, any future product candidate, or potentially discontinue operations.

To the extent that we raise additional capital through the sale of our equity or convertible debt securities, and pursuant to the exercise of the warrants issued to the investors in our prior public offerings, the ownership interest of our equity holders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our equity holders. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights to our technologies, future revenue streams, research programs or proposed products, 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 drug development or future commercialization efforts or grant rights to develop and market any future product that we would otherwise prefer to develop and market ourselves.

Summary Statement of Cash Flows

As of March 31, 2025, we had approximately $11,553,000 in cash and cash equivalents and investments in marketable securities. The table below presents our cash flows for the three month periods ended March 31, 2025 and 2024:

​

​

Operating Activities

Net cash used in operating activities was approximately $2,594,000 and $1,434,000 in the three months ended March 31, 2025 and 2024, respectively. The increase in 2025 was mostly due to an increase in net loss, offset by an increase in stock based compensation, and increase in accounts payable and accrued expenses and a decrease in prepaid expenses.

Investing Activities

Investment activities provided net cash of $2,770,000 and used net cash of $4,466,000 in the three months ended March 31, 2025 and 2024, respectively. The cash provided in investing activities for the three months ended March 31, 2025 consisted of net sales of US Treasury Bills and Notes. The cash used in investing activities for the three months ended March 31, 2024 consisted of net purchases of short maturity US Treasury Bills and Notes from the proceeds of our March 2024 public offering (the “March 2024 Offering”).

Financing Activities

Net cash provided by financing activities was approximately $23,000 for the three months ended March 31, 2025. The net cash provided increased due to the receipt of approximately $173,000 in net proceeds from the exercise of warrants, partially offset by repayments of amounts due to officers of $150,000. Net cash provided by financing activities was approximately $5,332,000 for the three months ended March 31, 2024. The net cash provided increased due to the receipt of approximately $5.5 million in net proceeds from the March 2024 Offering partially offset by repayments of amounts due to officers of $150,000.

Research and Development Commitments

In October 2019, Quoin Inc. entered into the Exclusive Licensing Agreement (as amended from time to time, the “License Agreement”) with Skinvisible Pharmaceuticals, Inc. (“Skinvisible”), under which Skinvisible granted us an exclusive royalty-bearing license relating to the production and manufacture of prescription drug products related to certain patents held by Skinvisible, including those related to QRX003 and QRX004. We made Skinvisible a one-time non-refundable, non-creditable license fee of $1 million (the “License Fee”). In addition, we agreed to pay Skinvisible a single digit royalty percentage of our net sales revenues for any licensed product covered by the patent rights licensed under the License Agreement. We also agreed to pay Skinvisible 25% of any revenues we receive as royalties in the event that we sublicense any licensed products to a third party. The License Agreement also requires that we make a $5 million payment to Skinvisible upon receiving approval in the U.S. or European Union, whichever occurs first, for the first drug product developed using intellectual property licensed thereunder.

In November 2020, Quoin Inc. entered into a Master Service Agreement with Therapeutics Inc. for the management of the preclinical and clinical development of QRX003 for Netherton Syndrome. The initial term of the agreement was three years with automatic one year extensions, and the agreement required the execution of individual work orders. Quoin Inc. may terminate any work order for any reason with 90 days written notice subject to costs incurred through termination and a defined termination fee, unless there is a material breach by Therapeutics Inc. A work order was entered into in June 2022 for the first QRX003 clinical study at an expected estimated cost of approximately $4.4 million through 2024. An additional change order was entered into in December 2022 for a second QRX003 clinical study at an expected estimated cost of approximately $830,000. An amended and restated change order for the two studies was entered into in December 2024 at an estimated total remaining cost from August 2024 of approximately $3.6 million for the two studies combined. For the three months ended March 31, 2025 and 2024, we incurred research and development expenses under these agreements of approximately $411,000 and $489,000 respectively.

In November 2021, we entered into a research agreement with Queensland University of Technology (QUT) for a pre-clinical research program for the development of a product to treat Netherton Syndrome of approximately $250,000. In May 2022, we entered into a second research agreement with QUT for the development of a product to treat Scleroderma of approximately $610,000. Each agreement remains in place until the completion of the research program, which in each case was initially anticipated to be 18 months from execution. For the three months ended March 31, 2025 and 2024, we incurred research and development costs related to these agreements of approximately $0 and $0 respectively. We are planning to schedule a meeting with QUT to discuss the future direction of both research programs.

On June 10, 2024, we entered into a research agreement with The School of Pharmacy at UCC. The scope of the agreement encompasses the development of novel topical formulations of Rapamycin (sirolimus) as potential treatments for a number of rare and orphan diseases for which there are currently very limited or no approved therapies or cures. Under the terms of the agreement, based on the achievement of certain milestones, we will fund up to approximately €567,000 ($614,000) plus VAT over an anticipated 2-1/2 year period to support the UCC research program to investigate the development of a number of topical rapamycin formulations for future development as potential treatments for several rare and orphan diseases. Following completion of the research program, we will have the option to advance the clinical development of rapamycin formulations developed by UCC. Work on this research project commenced in December 2024. For the three months ended March 31, 2025, we incurred $60,000 of research and development costs related to this agreement.

Critical Accounting Estimates

There have been no material changes to our critical accounting estimates from the information provided in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” included in our Annual Report on Form 10-K for the year ended December 31, 2024.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company as defined in Rule 12b-2 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and are not required to provide the information otherwise required under this Item 3.

​

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, which are designed to provide reasonable assurance that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation, as of the end of the period covered by this report, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15e under the Exchange Act). Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

During the quarter ended March 31, 2025, there were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

​

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

From time to time, we may become involved in legal or administrative proceedings or be subject to claims arising in the ordinary course of our business. We are currently not a party to any material legal or administrative proceedings, and we are not aware of any pending or threatened material legal or administrative proceedings against us.

Item 1A. Risk Factors.

Except as set forth below, there have been no material changes in our risk factors from the risks previously reported in Part 1, Item 1A, “Risk Factors” of our Form 10-K. You should carefully consider the factors discussed in Form 10-K, which could materially affect our business, financial condition or future results. The risks described in our Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. We may disclose changes to such factors or disclose additional factors from time to time in our future filings with the SEC.

Our failure to meet the continued listing requirements of The Nasdaq Capital Market could result in a delisting of our ADSs.

Our ADSs are listed on the Nasdaq Capital Market, which imposes, among other requirements, a minimum bid requirement.

On April 29, 2024, we received a letter from the Listing Qualifications staff of The Nasdaq Stock Market, LLC (“Nasdaq”) notifying the Company that the closing bid price per ADS was below the required minimum of $1.00 for a period of 30 consecutive business days and that the Company did not meet the Minimum Bid Price Requirements set forth in Nasdaq Listing Rule 5550(a)(2). Pursuant to Nasdaq Rule 5810(c)(3)(A), the Company had an initial period of one hundred eighty (180) calendar days, or until October 29, 2024, which was subsequently extended a further one hundred eighty (180) calendar days, or until April 28, 2025 (the “Compliance Period”), to regain compliance with Nasdaq’s Minimum Bid Price Requirement. To regain compliance with the Nasdaq Listing Rules, on April 9, 2025, we effected a change in the ratio of ADSs evidencing Ordinary Shares from one (1) ADS representing one (1) Ordinary Share to one (1) ADS representing thirty-five (35) Ordinary Shares. On April 29, 2025, we received a letter from Nasdaq stating that the Company’s closing bid price per ADS was at $1.00 or greater for the last 13 consecutive business days. Accordingly, we regained compliance with Listing Rule 5550(a)(2) and the matter was closed.

There can be no assurance that we will be able to maintain compliance with Nasdaq’s Minimum Bid Price Requirement for continued listing. If our ADSs are delisted from Nasdaq, it will have a material negative impact on the actual and potential liquidity of our securities, as well as a material negative impact on our ability to raise future capital.

If we fail to meet any of Nasdaq’s listing standards, our ADS will be subject to delisting. If that were to occur, our ADS would be subject to rules that impose additional sales practice requirements on broker-dealers who sell our securities. The additional burdens imposed upon broker-dealers by these requirements could discourage broker-dealers from effecting transactions in our ADS. This would adversely affect the ability of investors to trade our ADS and would adversely affect the value of our ADS. Delisting from Nasdaq would cause us to pursue eligibility for trading of our ADS on other markets or exchanges, or on an over-the-counter market. In such case, our stockholders’ ability to trade or obtain quotations of the market value of our ADS would be severely limited because of lower trading volumes and transaction delays. These factors could contribute to lower prices and larger spreads in the bid and ask prices of these securities. There can be no assurance that our ADS, if delisted from Nasdaq, would be listed on a national securities exchange, a national quotation service or the over-the-counter markets. Delisting from Nasdaq could also result in negative publicity, adversely affect the market liquidity of our ADS, decrease securities analysts’ coverage of us or diminish investor, supplier and employee confidence. In addition, our stock could become a “penny stock,” which would make trading of our ADS more difficult.

The delisting of our ADS from Nasdaq may make it more difficult for us to raise capital on favorable terms in the future, or at all. Such a delisting would likely have a negative effect on the price of our ADS and would impair your ability to sell or purchase our ADS when you wish to do so. Further, if our ADS were to be delisted from Nasdaq, our ADS would cease to be recognized as a covered security, and we would be subject to additional regulation in each state in which we offer our securities. Moreover, there is no assurance that the actions that we have taken to restore our compliance with the Nasdaq Minimum Bid Price Requirement will stabilize the market price

or improve the liquidity of our ADS, prevent our ADS from falling below the Nasdaq minimum bid price required for continued listing again or prevent future non-compliance with other applicable Nasdaq listing requirements.

We must raise additional capital to fund our operations in order to continue as a going concern.

At March 31, 2025, we had an accumulated deficit of approximately $59.0 million, cash and cash equivalent balances totaling $3.8 million and investments of $7.7 million. Despite our recent financing in December 2024, pursuant to which we raised gross proceeds of approximately $6.8 million, based on our current expected level of operating expenditures we believe our cash and cash equivalents and investments on hand, management has concluded that there is substantial doubt about our ability to continue as a going concern for a period of at least one year from the issuance of the unaudited consolidated financial statements included in this report. We will need to raise further capital through the sale of additional equity or debt securities or other debt instruments, strategic relationships or grants, or other arrangements to support our future operations. We do not expect to generate revenue from product sales unless and until we successfully complete development and obtain marketing approval for one or more of our product candidates, which we expect will take a number of years and is subject to significant uncertainty. If we are unable to improve our liquidity position, we may not be able to continue as a going concern. Our ability to continue as a going concern is dependent upon our ability to generate revenue and raise capital from financing transactions. There can be no assurance that we will be successful in accomplishing these objectives. Without such additional capital, we may be required to curtail or cease operations and be required to realize our assets and discharge our liabilities other than in the normal course of business which could cause investors to suffer the loss of all or a substantial portion of their investment.
