Quoin Pharmaceuticals Announces Submission of IND for its Lead Asset, QRX003, for Netherton Syndrome

Quoin Anticipates Initiating Clinical Testing in Q2 2022

ASHBURN, Va., March 15, 2022 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (the “Company” or “Quoin”), a specialty pharmaceutical company focused on rare and orphan diseases, today announced that its wholly-owned subsidiary, Quoin Pharmaceuticals, Inc., has submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration (FDA) for QRX003, the Company’s investigational product for Netherton Syndrome, a rare and devastating genetic disease for which there is currently no available treatment or cure.

QRX003 is a topical lotion, formulated with a proprietary delivery technology, and contains a broad-spectrum serine protease inhibitor, whose mechanism of action is intended to perform the function of a specific protein, called LEKTI. The absence of LEKTI in Netherton patients leads to excessive skin shedding resulting in a highly porous and compromised skin barrier. Daily application of QRX003 could potentially lead to improvement in skin architecture and restoration of the skin’s barrier properties, resulting in substantially improved quality of life for patients with Netherton Syndrome.

“This is an important milestone for Quoin, and we’d like to thank everyone who participated in the preparation of the IND submission. We look forward to initiating clinical testing of QRX003 in this very underserved patient population,” said Dr. Michael Myers, Chief Executive Officer of Quoin.

About Netherton Syndrome

Netherton Syndrome, a form of Ichthyosis, is a rare, hereditary skin disorder caused by a mutation in the SPINK5 gene (serine protease inhibitor, Kazal Type 5) that leads to severe skin barrier defects and recurring infections, as well as a pronounced predisposition to allergies, asthma, and eczema. Patients also often suffer from severe dehydration, chronic skin inflammation and stunted growth.

Currently, there is no cure for Netherton Syndrome, nor are there any approved therapeutic treatments.
