QRX003 (QYLEKI 4% lotion) is in Phase 2 whole-body clinical trials, with a pivotal Phase 3 study expected to start in the second half of 2026 and a potential New Drug Application filing anticipated in 2027. The product has Orphan Drug Designation in the U.S., European Union, and Japan, and has also received Fast Track and Rare Pediatric Disease designations from the FDA, in an area where there is currently no approved treatment.

Quoin Pharmaceuticals reports that Japan’s Ministry of Health, Labour and Welfare has granted Orphan Drug Designation to QRX003 lotion (4%) for treating Netherton Syndrome, a rare genetic skin disorder with no approved treatments.

The Japanese designation covers diseases affecting fewer than 50,000 patients and provides prioritized consultation, reduced fees, tax incentives, priority review, and up to 10 years of market exclusivity upon approval.

QRX003 already holds Orphan Drug, Pediatric Rare Disease, and Fast Track designations from the U.S. FDA and Orphan Drug status from the European Medicines Agency. The drug is in Phase 2 trials, with a pivotal Phase 3 study expected in the second half of 2026 and potential NDA filing in 2027.
