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 no approved treatments or cures. Our initial focus is on the development of products, using our proprietary owned and in-licensed drug delivery technologies, that could help address rare genetic diseases. Our lead product, QRX003, is under 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 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 the 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 currently no approved therapies or cures. Other development products in our pipeline include QRX004 as a potential treatment for Recessive Dystrophic Epidermolysis Bullosa.

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 under clinical development as a potential treatment for Netherton Syndrome, a rare hereditary genetic disease. QRX003 is entering pivotal registrational clinical testing under an open IND application with the FDA. We have opened six clinical sites in the U.S. along with international sites that are being opened in the UK, Spain, France and the Netherlands. QRX003 is currently being tested in seven pediatric NS patients in investigator-initiated studies in Ireland, Austria, the Netherlands and New Zealand. QRX003 is also being developed as a potential treatment for Peeling Skin Syndrome with the first subject being treated in New Zealand. We are in the process of expanding this study to include up to an additional five pediatric subjects. We entered into a Research Agreement with QUT, under which we have obtained an option for a global license to QRX008 for the potential treatment of scleroderma, as well as a Research Agreement with UCC 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, including microcystic lymphatic malformations, venous malformations and angiofibromas among others. We have also entered into 9 commercial partnerships for QRX003 spanning 61 countries outside of our core commercial territories of the U.S., Western Europe and Japan. These partnership countries include Canada, Australia, New Zealand, the Middle East, China, Taiwan, Hong Kong Singapore, Israel, Central and Eastern Europe, Turkey as well as several countries in Latin America.

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”.

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 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 ($608,000) 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 and we accrued $10,000 in research and development costs for the year ended December 31, 2024.

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 accrue for costs incurred by external service providers, including contract research organizations and clinical investigators, based on its estimates of service performed and costs incurred. These estimates include the level of services performed by third parties, patient enrollment in clinical trials when applicable, administrative costs incurred by third parties, and other indicators of the services completed. Based on the timing of amounts invoiced by service providers, we may also record payments made to those providers as prepaid expenses that will be recognized as expense in future periods as the related services are rendered.

We recognize compensation costs resulting from the issuance of stock-based awards to employees, non-employees and directors as an expense in the consolidated statements of operations over the requisite service period based on a measurement of fair value for each stock-based award. The fair value of each option grant is estimated as of the date of grant using the Black-Scholes option-pricing model, net of actual forfeitures. The fair value is amortized as compensation cost on a straight-line basis over the requisite service period of the awards, which is generally the vesting period.

Since we have a limited history of trading as a public company, our expected stock volatility is based on a weighting of its historical volatility along with a group of a publicly traded set of peer companies. We utilize the simplified method to estimate the expected term. The risk-free interest rate was determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield was assumed to be zero as we have not paid dividends since our inception and we do not anticipate paying dividends in the foreseeable future.

We recognize impairment when the sum of the expected undiscounted future cash flows is less than the carrying amount of the asset. Impairment losses, if any, are measured as the excess of the carrying amount of the asset over its estimated fair value. During the year ended December 31, 2024 there was no impairment indicator which required an impairment loss measurement. During the year ended December 31, 2023, there was one impairment indicator which required an impairment loss measurement (see Note 10 to the Consolidated Financial Statements included in this Annual Report).
