(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 second quarter of 2023, ended June 30, 2023. Quoin CEO, Dr. Michael Myers, said, “We are excited to announce positive clinical data for the first subject to complete our ongoing open—label clinical study in Netherton Syndrome patients. While we strongly caution that this data is just from a single subject, the positive nature of the data across all assessed clinical endpoints is indeed noteworthy. With both of our clinical studies on track to having a majority of patients enrolled by the end of August, we look forward to releasing additional clinical data in due course. I am also pleased to announce that across both ongoing clinical studies to date, QRX003 is demonstrating an exemplary safety profile. The generation of this first clinical data is a milestone for Quoin and we hope that it could represent an important step towards providing a safe and effective treatment for such a devastating disease.” Corporate Highlights – On May 24th 2023, less than 3 months after the first patient had been dosed in its open label clinical trial in Netherton Syndrome patients, Quoin announced that the study had achieved 50% enrollment. The trial is a single arm, open label study, investigating the safety and efficacy of Quoin’s lead candidate, QRX003, in Netherton Syndrome patients who are currently receiving off-label systemic therapy, primarily biologic therapy, and will continue to do so throughout the duration of the study.Today, the company is announcing positive clinical data for the first patient to complete testing in the company’s open-label study in Netherton Syndrome patients. As determined by the clinical site Investigator, the subject’s skin was assessed to be fully clear at the QRX003 treatment sites on completion of the study. The subject’s skin was also assessed to be clear by a well-recognized visual scoring index. Importantly, the subject also had a positive impression of QRX003 across a number of metrics. Furthermore, the patient’s pruritis or itch at the QRX003 treatment site was negligible, representing a substantial improvement from baseline.During the quarter, the company began assessing a number of other potential supportive studies for QRX003 in Netherton Syndrome outside of the US, including one in pediatric patients, and one in pre-identified patients in the Middle East.Also, during the quarter, Quoin continued to advance its two rare disease research programs with Queensland University of Technology for treatment of Scleroderma and Netherton Syndrome and anticipates initiation of clinical testing in Australia for at least one of these programs in 2H 2023.Progress was made during the quarter towards the initiation of proof of concept clinical testing for QRX003 in other indications including SAM Syndrome, Peeling Skin Syndrome and Palmoplantar Keratoderma Financial Highlights Quoin had approximately $15.4 million in cash, cash equivalents and marketable securities as of June 30, 2023.Net loss for the quarter ended June 30, 2023 was approximately $2.1 million compared to approximately $2.7 million for the quarter ended June 30, 2022, and net loss for the six months ended June 30, 2023 was $4.7 million compared to $4.4 million for the six months ended June 30, 2022.Investors are encouraged to read the Company’s Quarterly Report on Form 10-Q when it is filed with the Securities and Exchange Commission (the “SEC”), which will contain additional details about Quoin’s financial results as of and for the period ended June 30, 2023.
