Supports Quoin’s planned direct commercialization of QRX003 in Japan, one of its three core commercial territories
Follows recent grant of Orphan Drug Designation to QRX003 by Japan’s MHLW
ASHBURN, Va., June 18, 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 it has completed the establishment of a wholly-owned subsidiary in Japan as part of its strategy to directly commercialize QRX003 for the treatment of Netherton Syndrome, if approved. The formation follows the recent grant of Orphan Drug Designation to QRX003 by Japan’s Ministry of Health, Labour and Welfare (MHLW) and supports Quoin’s long-term commercial plans in one of its three core markets.
A local corporate presence allows Quoin to engage directly with Japanese regulators, clinicians, and patient advocacy organizations as it builds the commercial infrastructure to support a potential launch. Japan is one of Quoin’s core territories, along with the United States and Western Europe, in which Quoin intends to self-commercialize QRX003 and its other pipeline products. Outside of these territories, Quoin has established nine commercial partnerships for QRX003 spanning sixty one countries, which combined with the company’s core territories, could facilitate almost global availability of the product if approved.
QRX003 has now received Orphan Drug Designation for Netherton Syndrome in the United States, the European Union, and Japan, providing development and commercial incentives across all three of Quoin’s core commercial territories.
“Establishing our Japanese subsidiary is another important step forward in our plan to self-commercialize QRX003 in one of our three core markets and follows the earlier establishment of Quoin Therapeutics, Ireland, our Western European subsidiary,” said Dr. Michael Myers, Chief Executive Officer of Quoin Pharmaceuticals. “With Orphan Drug Designation now secured in the United States, Europe, and Japan, we are continuing to build the commercial infrastructure in advance of a potential approval. Establishing our presence in Japan now reflects both our confidence in QRX003 and our long-term commitment to this very attractive market.”
QRX003 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. If approved, QRX003 has the potential to become the first approved treatment for Netherton Syndrome. Quoin is working closely with leading Japanese clinicians to refine the clinical and regulatory pathway for approval of QRX003 for the treatment of Netherton Syndrome.
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.
