Quoin Pharmaceuticals, Inc.: Quoin Pharmaceuticals Announces Further Clinical Evidence of QRX003 Effectiveness in Netherton Syndrome

Finanznachrichten News
  • Four Weeks After Discontinuation of Treatment with QRX003 Complete Reversal of Positive Clinical Improvements Across all Measured Endpoints Observed
  • Data Supports QRX003 Mechanism of Action as a Competitive Broad Spectrum Serine Protease Inhibitor

ASHBURN, Va., Jan. 23, 2025 (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 further clinical evidence of the potential efficacy of QRX003 in Netherton Syndrome.

In December 2024 and January 2025, Quoin announced positive data from the mid-point and at completion of 12 weeks of testing the first subject dosed twice-daily in Quoin's ongoing open-label study which demonstrated evidence of clear improvement across all measured clinical endpoints. Today Quoin is sharing additional data on that subject at 4 weeks post-discontinuation of treatment with QRX003. As the table below illustrates all of the positive clinical benefits observed after 12 weeks of testing with QRX003 were completely reversed by 4 weeks after discontinuation of treatment resulting in the subject's disease state reverting to the baseline status observed prior to QRX003 treatment. These results strongly indicate that ongoing, chronic treatment with QRX003 is necessary for a continued positive clinical outcome in Netherton Syndrome patients.

*M-IASI: Modified Ichthyosis Area of Severity Index, a score used to assess the severity and extent of skin symptoms associated with ichthyosis. Lower scores indicate improvement.
**WINRS: Worst Itch Numeric Rating Scale, which measures the severity of itch on an 11-point scale (0 = no itch, 10 = worst imaginable itch).
***IGA: Investigator's Global Assessment, which uses descriptive categories (e.g., clear, mild, moderate, severe) to evaluate the overall severity of Netherton Syndrome symptoms.

Quoin CEO, Dr. Michael Myers, said, "This data set provides the clearest clinical evidence to date that the active ingredient in QRX003 is a competitive broad spectrum serine protease inhibitor and that discontinuation of treatment with QRX003 results in a complete reversal of all clinical benefits derived from continued treatment with the product. The rapid reversal of all observed clinical benefits to baseline disease status after just 4 weeks of treatment discontinuation serves to further underscore that chronic, whole-body treatment with QRX003 is potentially required to maintain the positive clinical outcomes observed in our clinical study. These results increase our commitment to complete the clinical development of QRX003 as expeditiously as possible with a goal of making the product widely available to the Netherton community once approved.

With four clinical studies in Netherton subjects underway, three of which are being conducted under an open Investigational New Drug (IND) application with the FDA, we believe Quoin is assembling a broad and diverse clinical data package to support a New Drug Application (NDA) filing for QRX003 as potentially the first approved treatment for Netherton Syndrome."

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.
