ASHBURN, Va., September 8, 2026 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (“Quoin” or the “Company”), a late clinical-stage specialty pharmaceutical company focused on rare and orphan diseases, today announced that the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease (RPD) Designation for the Company’s lead asset, QRX003, for the treatment of Peeling Skin Syndrome (PSS).
The designation reinforces the potential of QRX003 as a therapeutic candidate for a profoundly underserved pediatric population. This is the second RPD designation granted for QRX003, following the previously granted RPD designation for Netherton Syndrome.
The FDA’s Rare Pediatric Disease Designation program is intended to encourage the development of new therapies for serious and life-threatening diseases that primarily affect individuals under 18 years of age. If a New Drug Application (NDA) for QRX003 is approved, Quoin may qualify to receive a Priority Review Voucher (PRV), which can be redeemed to receive priority review for another marketing application or may be sold or transferred.
“We are very pleased to announce the receipt of Rare Pediatric Disease Designation for QRX003 for Peeling Skin Syndrome,” said Dr. Michael Myers, Chief Executive Officer of Quoin Pharmaceuticals. “With the IND cleared by FDA, the Quoin team is preparing to initiate the Phase 2 clinical study before the end of this year with plans to enroll up to 12 pediatric and adult Peeling Skin patients in the U.S. and Europe. This will be the first formal study ever conducted in the U.S. for this disease under an open IND.”
About Peeling Skin Syndrome (PSS)
Generalized inflammatory peeling skin syndrome (PSS) is a rare autosomal recessive genodermatosis caused by loss-of-function disease-causing variants of the corneodesmosin gene (CDSN), resulting in excessive shedding of the superficial layers of the epidermis. Patients generally suffer from a variety of conditions including severe pain and chronic pruritus (itch). There is currently no approved treatment for PSS.
