ASHBURN, Va., June 23, 2026 (GLOBE NEWSWIRE) -- 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 the U.S. Food and Drug Administration (FDA) has conditionally approved QYLEKI™ as the proposed brand name for QRX003, the Company’s investigational product candidate for the treatment of Netherton Syndrome. FDA acceptance of the Company’s proposed brand name represents yet another important milestone for Quoin as it executes on its mission to deliver the first approved treatment for Netherton Syndrome. A request for proprietary name review and final approval for QYLEKI will be included in a New Drug Application (NDA) for QRX003.
Key Facts
| · | The FDA has conditionally accepted QYLEKI™ as the proposed brand name for QRX003, Quoin's investigational topical treatment for Netherton Syndrome. | |
| · | QRX003 holds Orphan Drug Designation in the United States, the European Union, and Japan. | |
| · | The FDA has also granted QRX003 Fast Track and Rare Pediatric Disease Designations. | |
| · | Quoin's pivotal Phase 3 study is expected to initiate in the second half of 2026. | |
| · | A potential NDA filing is anticipated in 2027. | |
| · | There is currently no approved treatment for Netherton Syndrome. If approved, QRX003 could become the first. |
The proposed name QYLEKI (pronounced “Key-Lek-ee”) was developed in accordance with the FDA’s guidance on proprietary names. Final approval of the QYLEKI brand name will be obtained upon FDA marketing approval of QRX003.
“The designation of a brand name for the first potentially approved treatment for Netherton Syndrome represents another important step for Quoin, our commercial partners and most importantly, the Netherton community as a whole.” said Dr. Michael Myers, Chief Executive Officer and Co-Founder of Quoin Pharmaceuticals. “FDA conditional approval of the QYLEKI brand name reflects the continued progress we are making toward potential commercialization of the product and complements the regulatory recognition the product has received in the United States, Europe, and Japan. Having just released a positive update from our ongoing Pediatric Compassionate Use Program and with our pivotal Phase 3 study expected to commence later this year, this is an extremely exciting time for Quoin as we remain fully focused on delivering QYLEKI to patients as what could be the first approved treatment for Netherton Syndrome.”
QYLEKI Development and Regulatory Status
QYLEKI 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 a potential NDA filing in 2027. QYLEKI has received Orphan Drug Designation in the United States, the European Union, and Japan, along with Fast Track and Rare Pediatric Disease Designations from the FDA, providing regulatory recognition across Quoin’s three core commercial territories.
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.
