Exhibit 99.1
Quoin Pharmaceuticals Announces Japan's MHLW Grants Orphan Drug Designation for QRX003 in Netherton Syndrome
-Designation provides regulatory and development incentives in Japan, including up to 10 years of market exclusivity upon approval-
-Follows Orphan Drug Designation, Pediatric Rare Disease Designation, and Fast Track Designation previously granted by the U.S. FDA, and Orphan Drug Designation previously granted by the European Medicines Agency-
-Quoin is working closely with leading Japanese clinicians to refine clinical and regulatory pathway for approval-
ASHBURN, Va., June 4, 2026 — 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 Japan's Ministry of Health, Labour and Welfare (MHLW) has granted Orphan Drug Designation to QRX003 for the treatment of Netherton Syndrome, a rare and severe genetic skin disorder for which there are currently no approved treatments.
The MHLW grants Orphan Drug Designation to medicines intended to treat rare diseases that affect fewer than 50,000 patients in Japan and for which there is high unmet medical need. The designation provides certain development incentives, including prioritized consultation, reduced consultation and application fees, tax incentives, priority review of applications, and up to 10 years of market exclusivity upon approval.
The MHLW designation adds to the global regulatory recognition QRX003 has received for Netherton Syndrome, which includes Orphan Drug Designation, Pediatric Rare Disease Designation, and Fast Track Designation from the U.S. Food and Drug Administration, and Orphan Drug Designation from the European Medicines Agency. Quoin has also filed an application for Breakthrough Medicine Designation with the Saudi Food and Drug Authority.
"Receiving Orphan Drug Designation from Japan's MHLW adds an additional important regulatory milestone for QRX003 and its potential as a safe and effective treatment for Netherton Syndrome," said Dr. Michael Myers, CEO of Quoin Pharmaceuticals. "Japan is a strategically important market for QRX003, and, along with the US and Western Europe, is one of three core territories in which we plan to self-commercialize QRX003 and our other pipeline products, once approved. This designation is another important step in that strategy and complements the regulatory recognition QRX003 has received in the United States and Europe."
QRX003 lotion (4%) is currently being evaluated in Phase 2 whole-body clinical trials in patients with Netherton Syndrome. Quoin's pivotal Phase 3 study is expected to initiate in the second half of 2026, with potential NDA filing in 2027. Quoin is working closely with leading Japanese clinicians to refine the clinical and regulatory pathway for approval of QRX003 for the treatment of Netherton Syndrome.
About Netherton Syndrome
Netherton Syndrome is a rare, inherited skin disorder caused by mutations in the SPINK5 gene, leading to severe skin barrier dysfunction, chronic inflammation, and a heightened risk of infections and allergic complications. Patients often experience widespread skin redness, scaling, persistent itching, and significant impairment in quality of life. There are currently no FDA-approved therapies for the treatment of Netherton Syndrome, and treatment options are limited to supportive care and off-label therapies.
