The FDA clearance is a positive regulatory milestone for Quoin Pharmaceuticals, potentially expanding its pipeline and addressing an unmet medical need. However, the stock declined over 8% in pre-market trading, possibly due to profit-taking or market skepticism about the small study size and long timeline to approval.
Quoin Pharmaceuticals Ltd. announced that the U.S. United States — Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for QRX003 for the treatment of Peeling Skin Syndrome (PSS), enabling initiation of a Phase 2 clinical study.

The FDA expressed no safety concerns regarding study design or dosing duration. Quoin also plans to complete enrollment in its Phase 3 study for Netherton Syndrome by end of 2026 and seek FDA approval in 2027. Quoin's stock fell over 8% in pre-market trading following the announcement.
