ASHBURN, Va., March 26, 2026 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (the "Company" or "Quoin"), a late clinical-stage specialty pharmaceutical company focused on rare and orphan diseases, today announced recent corporate achievements and provided an update on its fourth quarter and full-year 2025 progress for the period ended December 31, 2025.
“2025 was a defining year for Quoin as we transitioned from clinical stage to a company actively preparing for commercial readiness,” said Michael Myers, Chief Executive Officer and Co-Founder of Quoin Pharmaceuticals. “We strengthened our balance sheet with a significant financing, secured key regulatory designations across our core territories, and continued to advance the clinical development of QRX003 supported by encouraging long-term efficacy data demonstrating durable treatment effect with no reported safety concerns. With Orphan Drug Designations in place in the United States and Europe, and confirmation of eligibility for Orphan Drug Designation and Fast Track review in Japan, QRX003 is now aligned with expedited regulatory pathways in our key target markets. In the United States, QRX003 was also awarded Rare Pediatric Disease Designation by the U.S. Food and Drug Administration (FDA) for Netherton Syndrome, which, if approved, could result in the receipt of a freely tradable Priority Review Voucher, with a potential value to Quoin of $150-$200 million in non-dilutive cash. Based on positive initial clinical data from our ongoing Peeling Skin Syndrome study, we are increasing the size of this study to 6 subjects, and we are planning to submit an Investigational New Drug application to the FDA in the second half of this year. In addition, we are planning to initiate clinical testing of QRX003 in Ichthyosis and SAM syndrome potentially putting the product on track for approval for four rare genetic diseases where there are currently no approved treatments. Finally, we are moving forward with our topical rapamycin program. We are targeting initiating clinical testing in at least one indication in the second half of this year and we believe our optimized delivery technologies may offer competitive advantages over more conventional topical formulations of rapamycin. All in all, we are excited at what 2026 could bring for our company and the patient populations we serve. We have begun the year with strong forward momentum with a platform poised to succeed on multiple fronts.”
Recent Accomplishments
On January 20, 2026, Quoin filed an application for Breakthrough Medicine Designation with the Saudi Food and Drug Authority (SFDA) for QRX003. If granted, the designation could enable accelerated regulatory review and availability in Saudi Arabia as early as the second half of 2026.
On January 27, 2026, Quoin submitted an application to Japan’s Ministry of Health, Labour and Welfare (MHLW) seeking Orphan Drug Designation for QRX003. The MHLW confirmed that QRX003 qualifies for both Orphan Drug Designation and Fast Track review in Japan.
On February 3, 2026, the U.S. Rare Pediatric Disease Priority Review Voucher (PRV) program was extended by Congress through September 30, 2029 as part of the Give Kids a Chance Reauthorization Act. QRX003 previously received Rare Pediatric Disease Designation from the U.S. Food and Drug Administration (FDA) in June 2025. Upon approval of QRX003, Quoin would be eligible to receive a Priority Review Voucher which, if awarded, may be used to obtain priority review for another product or sold or transferred.
On February 26, 2026, in recognition of Rare Disease Day 2026, Quoin highlighted continued momentum of its NETHERTON NOW awareness campaign, which has reached nearly 2 million video views and more than 24 million impressions globally since launch.
Fourth Quarter and Full-Year 2025 Highlights
Closed Private Placement Financing
On October 10, 2025, Quoin closed a private placement financing raising up to $104.5 million in gross proceeds, including $16.5 million at closing and up to $88.0 million upon potential exercise of accompanying warrants.
Advancement of QRX003 for Netherton Syndrome
On October 21, 2025, the U.S. FDA granted Orphan Drug Designation to QRX003 for the treatment of Netherton Syndrome. Orphan status in the United States, together with previously granted Orphan Drug Designation in Europe, provides important potential benefits, including market exclusivity upon approval, tax credits for clinical testing and fee reductions.
On October 28, 2025, Quoin reported positive nine-month pediatric data demonstrating sustained skin healing, complete elimination of pruritus, and no adverse events in an investigator-led study of QRX003. This data further supports the long-term safety and efficacy profile of QRX003. This study has been expanded to 7 pediatric NS patients currently being treated with QRX003 in Ireland, Austria, the Netherlands and New Zealand.
On March 11, 2026, the U.S. FDA granted Fast Track Designation to QRX003 for the treatment of Netherton Syndrome. The FDA's Fast Track program is designed to facilitate the development and expedite the review of drugs that treat serious conditions and fill an unmet medical need. A therapy granted Fast Track Designation may benefit from more frequent interactions with the FDA, eligibility for rolling review of regulatory submissions, and potential qualification for Accelerated Approval and Priority Review, if relevant criteria are met.
On March 25, 2026, Quoin provided a clinical and regulatory update from its constructive Type C meeting with the U.S. FDA for QRX003 in NS. Quoin reported that the FDA indicated that a single Phase 3 study may be sufficient to support marketing approval in the U.S. and expressed openness to an alternative study design for Phase 3 that would likely not include a traditional upfront vehicle or placebo control. Quoin remains on track to initiate its Phase 3 Study and complete Phase 3 patient recruitment in 2026 and potentially file for NDA approval in 2027.
QRX003 is currently being evaluated in two whole-body clinical trials for the treatment of Netherton Syndrome and Quoin anticipates reporting topline data in the second half of 2026.
Peeling Skin and Topical Rapamycin Pipeline Programs
On May 14, 2025, the Company announced positive initial data from its investigator led Peeling Skin Syndrome (PSS) clinical study which is being conducted in a single patient in New Zealand. The Company is actively working to recruit up to an additional 5 pediatric subjects into this study and is planning to submit an IND to the FDA in the second half of this year.
On November 11, 2025, the Company announced that the target rapamycin loadings of 4% and 5% for its proprietary topical lotion and dermal patch platforms had been achieved. The Company plans to initiate proof of concept clinical testing in the second half of 2026 in at least one clinical indication. Quoin believes that its proprietary technologies have the potential to optimize the local delivery of rapamycin at the target site and may provide a key competitive advantage over other platforms.
Financial Highlights
Quoin had approximately $18.7 million in cash, cash equivalents and marketable securities as of December 31, 2025. The Company believes its year-end cash position will fund the Company’s operations into 2027.
Net loss for the quarter ended December 31, 2025, was approximately $4.3 million compared to approximately $2.3 million for the quarter ended December 31, 2024. Net loss for the twelve months ended December 31, 2025, was approximately $15.8 million compared to approximately $9.0 million for the twelve months ended December 31, 2024.
Investors are encouraged to read the Company’s Annual Report on Form 10-K when filed with the Securities and Exchange Commission, which will contain additional details about Quoin’s financial results as of and for the period ended December 31, 2025.
