Positive initial data and clean safety profile catalyze optimization plan
Size of both ongoing clinical trials significantly increased
Lower dose eliminated from blinded trial
Dosing frequency changed to twice-daily from once-daily for both trials

ASHBURN, Va., Dec. 13, 2023 (GLOBE NEWSWIRE) — Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (the “Company” or “Quoin”), a specialty pharmaceutical company focused on rare and orphan diseases, today announced that it has received U.S. Food and Drug Administration (FDA) clearance to implement a number of protocol amendments to its two ongoing clinical trials for QRX003, which is being developed as a potential treatment for Netherton Syndrome (NS). Both trials are being conducted under Quoin’s open Investigational New Drug Application (IND) for QRX003.

“We are extremely pleased to announce clearance of our clinical trial optimization plan for QRX003 in NS. Armed with positive initial data and a clean safety profile to date, we believe that these protocol amendments could ultimately result in the generation of a highly compelling data set which could support regulatory filings and approval for QRX003 as the first treatment for this terrible disease. These latest developments underscore Quoin’s continued commitment to delivering a safe and effective treatment for this very underserved patient population,” said Dr. Michael Myers, Chief Executive Officer of Quoin.

As a result of positive initial clinical data across multiple endpoints and a strong safety profile to date, Quoin has made a number of protocol amendments to both ongoing trials. The company believes that implementation of these protocol amendments may result in an even more robust data set and potentially more rapid approval with a broader label.

The number of subjects in the blinded trial is increased to 30 from 18. As a result of the positive safety profile observed to date, the lower 2% dose has been eliminated from the trial going forward. All subjects will now receive either 4% QRX003 or a placebo vehicle, both of which will be applied twice-daily instead of the current once-daily treatment.

The number of subjects in the open-label trial is increased to 20 from 10, and the dosing frequency will also be twice-daily going forward. All subjects in this trial will continue to receive off-label systemic therapy throughout the duration of treatment.

All current clinical endpoints for both trials will remain the same and Quoin plans to open additional clinical sites to efficiently accommodate this increase in the number of enrolled subjects. Interest from subjects and clinical investigators continues to be very high and Quoin remains the only company actively recruiting subjects into NS clinical trials that are being conducted under an open IND.

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.

About QRX003

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. QRX003 is designed to lead to a more normalized skin shedding process and the formation of a stronger and more effective skin barrier.
