*– Filed Breakthrough Medicine Designation Application with Saudi FDA for QRX003 in Netherton Syndrome*

*– Submitted Application to Japanese MHLW for Orphan Drug Designation (ODD) for QRX003; MHLW Confirmed QRX003 Qualifies for Both Orphan Drug Designation and Fast Track Review*

*– Rare Pediatric Disease Priority Review Voucher Program Extended by Congress Through September 30, 2029*

*– On Track to Complete Phase 3 Patient Recruitment by End of 2026, with Potential NDA Filing in 2027 for QRX003 as the First Approved Treatment for Netherton Syndrome*

ASHBURN, Va., May 7, 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 first quarter 2026 progress for the period ended March 31, 2026.

"The first quarter of 2026 delivered meaningful regulatory progress on a number of fronts for QRX003 for Netherton Syndrome," said Dr. Michael Myers, Chief Executive Officer and Co-Founder of Quoin Pharmaceuticals. "In the United States, we were granted Fast Track Designation by the U.S. Food and Drug Administration (FDA). In addition, we had a constructive Type C meeting with FDA where the agency indicated that a single Phase 3 study may be sufficient to support marketing approval, with expressed openness to an alternative study design for Phase 3 that would likely not include a traditional upfront vehicle or placebo control. In Japan, we submitted our Orphan Drug Designation application following confirmation from MHLW that QRX003 qualifies for both ODD and Fast Track review. In Saudi Arabia, we filed for Breakthrough Medicine Designation, which could expedite the path to patient access, if granted. We also remain on track to complete Phase 3 recruitment this year and potentially file for NDA approval in 2027. On top of this, we have made substantial progress this year with our QRX009 topical rapamycin platform. Through engagement with KOLs and advocacy foundations, we are now in a position to initiate clinical testing in a number of indications later this year including investigator studies for Pachyonychia Congenita, Gorlin Syndrome and Tuberous Sclerosis Complex. We are also planning to submit an Investigational New Drug (IND) Application to the FDA for QRX009 for an additional indication by Q3 of this year. We believe the combination of our QRX003 platform for Netherton Syndrome and related diseases combined with our QRX009 topical rapamycin platform represents an intriguing value proposition for investors and we look forward to sharing more information on both throughout this year."

**First Quarter 2026 Highlights**

**Regulatory Progress for QRX003 in Netherton Syndrome:**

<u>On January 20, 2026</u>, 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. Quoin has an established distribution partnership with Genpharm for QRX003 in Saudi Arabia and other MENA countries.

<u>On January 27, 2026</u>, Quoin submitted an application to Japan's Ministry of Health, Labour and Welfare (MHLW) seeking Orphan Drug Designation for QRX003. MHLW confirmed that QRX003 qualifies for both Orphan Drug Designation and Fast Track review in Japan. The Company has also initiated the establishment of a Japanese subsidiary to facilitate self-commercialization of QRX003 in Japan, if approved.

<u>On February 3, 2026</u>, 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 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.

<u>On March 11, 2026</u>, the U.S. FDA granted Fast Track Designation to QRX003 lotion (4%) for the treatment of Netherton Syndrome. Fast Track status enables 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.

<u>On March 25, 2026</u>, Quoin provided a clinical and regulatory update from its constructive Type C meeting with the FDA for QRX003 in Netherton Syndrome. 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, such as a randomized withdrawal or randomized delayed start, that would likely not include a traditional upfront vehicle or placebo control. Quoin will submit clinical data from the ongoing Phase 2 and pediatric investigator studies and plans to request a meeting to discuss this data with the FDA prior to initiating the Phase 3 pivotal program to gain alignment on the design of the program. Quoin remains on track to complete patient recruitment into its Phase 3 program by the end of 2026 and to potentially file for FDA approval for QRX003 as the first treatment for Netherton Syndrome in 2027.

<u>On April 28, 2026</u>, Quoin provided a clinical and regulatory update for its QRX009 topical rapamycin development program, announcing the planned initiation of an investigator-led clinical study in Pachyonychia Congenita led by Professor Edel O'Toole, Queen Mary University of London as well as additional investigator-led studies in Gorlin Syndrome and Tuberous Sclerosis Complex. In addition, Quoin is targeting to submit an IND to the FDA for QRX009 for an additional indication in Q3 of 2026.

**Clinical Development:**

QRX003 lotion (4%) continues to be evaluated in late-stage whole-body clinical trials for the treatment of Netherton Syndrome, with topline data anticipated in the second half of 2026. The ongoing pediatric investigator-led study has been expanded to six children actively being treated with QRX003 in Ireland, Austria, the Netherlands, and New Zealand, representing the largest pediatric cohort of this age group ever studied in Netherton Syndrome.

**Pipeline Programs:**

Additional QRX003 Indications: Quoin continues to advance its Peeling Skin Syndrome (PSS) program, with the ongoing investigator-led study being expanded to six subjects. The Company plans to submit an IND to the FDA for PSS in Q2 of 2026.

QRX009 Development: Quoin also continues to advance its proprietary topical rapamycin platforms, which have achieved target loadings of 4% and 5% for the topical lotion and dermal patch, respectively. Investigator-led clinical studies are being planned for a number of indications including Pachyonychia Congenita, Gorlin Syndrome and Tuberous Sclerosis Complex and the Company is planning to submit an IND to the FDA for QRX009 for an additional indication before the end of Q3 of this year.

**Awareness and Advocacy:**

<u>On February 26, 2026</u>, 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.

**Financial Highlights**

Quoin had approximately $14 million in cash, cash equivalents and marketable securities as of March 31, 2026. The Company believes its current cash position will fund operations into 2027.

Net loss for the quarter ended March 31, 2026, was approximately $5 million compared to approximately $3.8 million for the quarter ended March 31, 2025.

Investors are encouraged to read the Company's Quarterly Report on Form 10-Q 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 March 31, 2026.
