ASHBURN, Va., March 08, 2023 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (the “Company” or “Quoin”), a clinical stage, specialty pharmaceutical company focused on rare and orphan diseases, today provides a business update and announces financial results for the fourth quarter and full year of 2022.

Quoin CEO, Dr. Michael Myers, said, “2022 as a whole was a year of significant progress for Quoin and the fourth quarter continued that trend of operational execution across a number of important metrics. We were very pleased to announce the dosing of the first patient in our ongoing double blinded, placebo controlled study in Netherton Syndrome patients. This study has continued to recruit and dose patients since then and overall interest in participation in the study remains very high.

We were also excited to announce in October our plans to initiate a second clinical trial in Netherton Syndrome patients which we believe further establishes the company’s leadership position related to this disease. Since then, Quoin has been cleared by the Food and Drug Administration (FDA) to initiate this study under the Company’s currently open Investigational New Drug (IND). This second study is investigating the safety and efficacy of QRX003 in Netherton Syndrome patients currently receiving off-label systemic therapy, primarily biologic therapy. Both of our clinical studies will be run concurrently with each other and utilize the same investigators and clinical sites, resulting in high levels of operational synergies and cost savings. As this second trial is a single arm, open label study, Quoin will have access to the data, which we look forward to sharing in the coming months. We believe Quoin is the only pharmaceutical company currently conducting two clinical trials in Netherton Syndrome patients under an open IND application.

We also continued to work closely with our 8 partners covering the 60 countries under our current commercial arrangements to determine requirements to advance QRX003 into Compassionate Use or Early Access Programs in the various local markets, in advance of formal regulatory approval. With the anticipated generation of clinical data this year, we are hopeful that this will provide a major step forward towards that goal.

Both of our dermatological rare disease research programs with Queensland University of Technology for treatment of Scleroderma and Netherton Syndrome continue to make progress under the expert scientific guidance of the program coordinators and we are working towards the initiation of clinical testing in Australia for at least one of these programs in 2H 2023.

Finally, last month we completed a public offering of our shares with aggregate net proceeds of approximately $6 million, which further extends our cash runway into 2H 2024.”
