Quoin Pharmaceuticals announced peer-reviewed publication in Dermatology and Therapy of a paper introducing QRX003 and a pediatric compassionate-use case in Netherton Syndrome. After 21 months of once-daily whole-body treatment, the patient's skin improved from severe (IGA 4) to fully clear (IGA 0), itch fell from WI-NRS 5 to 0, and no treatment-related adverse events were reported — the longest continuous QRX003 exposure to date.
