ASHBURN, Va., Aug. 07, 2025 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) ("Quoin" or the "Company"), a late clinical-stage specialty pharmaceutical company focused on rare and orphan diseases provided a corporate update today on its clinical progress and advocacy initiatives and announced its financial results for the second quarter ended June 30, 2025.

鈥淪econd quarter of 2025 was one of the most impactful in Quoin鈥檚 history, marked by meaningful progress on multiple fronts," said Dr. Michael Myers, Chief Executive Officer of Quoin Pharmaceuticals. "We continue to be encouraged by the positive and durable clinical improvements observed in our ongoing investigator-led pediatric Netherton Syndrome study. In addition, with the reporting of impressive Peeling Skin Syndrome data during the quarter, we are beginning to see the versatility of QRX003 as a potentially safe and effective treatment for a variety of rare skin diseases. We look forward to initiating additional studies in other indications in the coming months. From a regulatory standpoint, receiving Orphan Drug Designation in Europe and Rare Pediatric Disease Designation in the United States are important milestones for the Company which we believe will help accelerate the development of QRX003 and bring it to the patients who urgently need it. Additionally, our campaign continues to elevate awareness of the profound need for effective treatment options, reaching millions of people with education, advocacy, and powerful stories that highlight the faces of patients living with this disease, their family members who care for them and the clinicians who provide treatment for them each day without an FDA-approved therapy. With our late-stage trials advancing and global engagement expanding, we remain fully focused on delivering the first approved therapy for Netherton Syndrome."
