ASHBURN, Va., Oct. 22, 2024 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (the "Company" or "Quoin"), a clinical stage specialty pharmaceutical company focused on rare and orphan diseases, today announces the further expansion of its on-going Netherton Syndrome (NS) clinical studies to include two additional international sites in the United Kingdom (UK). These sites, Great Ormond Street Hospital and St. Thomas' Hospital, both in London, are recognized centers of excellence for treating Netherton Syndrome patients in the UK. Both sites have available cohorts of patients potentially eligible to participate in Quoin's studies. A Principal Investigator (PI) for the UK studies has been appointed and a Clinical Research Organization has been engaged.

Quoin CEO, Dr. Michael Myers, said, "We are very pleased to announce yet another exciting development for our ongoing clinical studies. This further international expansion into two highly renowned clinical centers in the United Kingdom, coupled with our intent to open additional sites in other Western European countries as well as in Eastern Europe, underscores our determination and commitment to complete enrollment into both studies as rapidly as possible with a view to potentially delivering the first approved treatment to this underserved patient population."
