Quoin Pharmaceuticals Initiates Clinical Testing of Lead Product in Pediatric Netherton Syndrome Patient

ASHBURN, Va., Nov. 05, 2024 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX), a clinical-stage specialty pharmaceutical company focused on novel treatments for rare and orphan diseases, today announced that it has initiated the testing of the safety and efficacy of QRX003 in a young child with Netherton Syndrome (NS), a rare inherited genetic disease. There is currently no approved treatment for NS and no cure.

The clinical assessment is being led by Dr. Alan Irvine, a consultant dermatologist at Children’s Health Ireland and professor of dermatology at Trinity College Dublin. Dr. Irvine is president of the International Eczema Council and an elected member of the Royal Irish Academy. He has published over 250 peer-reviewed papers in high-impact journals, including many on epithelial genetics.

“We are pleased to announce this latest initiative for Quoin as we strive to generate the broadest and most diverse data set possible for QRX003 in Netherton Syndrome patients. Furthermore, we are delighted that Professor Irvine, one of the world’s leading researchers in this disease, has agreed to perform this assessment of QRX003. Currently, we are testing patients aged 14 years and up in our two ongoing clinical studies and we hope that data generated by Professor Irvine will facilitate lowering the eligibility age further. In addition, we look forward to broadening the scope of this clinical assessment to include three additional pediatric subjects in Spain,” said Dr. Michael Myers, Quoin CEO.

QRX003 is Quoin’s most advanced pipeline product and is currently being evaluated in two late-stage clinical trials as a potential treatment for NS under an open Investigational New Drug application with the U.S. Food and Drug Administration. Clinical data generated to date for QRX003 in NS patients has been promising with all evaluable subjects demonstrating improvement across a number of endpoints with no treatment-related adverse events recorded. In addition to the five open clinical sites in the United States, a sixth site is opening in Saudi Arabia. On October 22, Quoin also announced the planned opening of two additional clinical sites in the United Kingdom, each of which has a cohort of patients potentially eligible for recruitment.

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 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.

About QRX003 QRX003 is a topical lotion formulated with a proprietary delivery technology that 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. QRX003 is designed to promote a more normalized skin-shedding process and the formation of a stronger and more effective skin barrier.
