News Release

Three clinical sites are now fully open; final three sites expected to open imminently

ASHBURN, Va., Sept. 13, 2022 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (the “Company” or “Quoin”), a specialty pharmaceutical company focused on rare and orphan diseases, has established a patient specific website: https://www.nethertonsyndromeclinicaltrials.com/, to facilitate patient awareness and participation in its ongoing clinical study evaluating QRX003 for the treatment of Netherton Syndrome.

The randomized, double blinded, vehicle-controlled study was initiated in June 2022 and will assess two different doses of Quoin’s topical lotion, QRX003, versus a placebo lotion in Netherton patients. The test materials will be applied once daily over a twelve-week period, to pre-designated areas of the patient’s body. Based on discussions with the FDA, a number of different clinical endpoints will be assessed in the study. The study is expected to be conducted across six clinical sites in the US. Three of these sites have already opened, with the remaining three sites expected to be fully opened in a matter of weeks.

Quoin CEO, Dr. Michael Myers, said, “As the pace of clinical trial site opening accelerates, we anticipate recruitment of patients in a timely manner. We believe the establishment of this patient specific website could be an effective tool to provide information about our clinical study and facilitate patient recruitment.”

QRX003 is Quoin’s lead product candidate and has the potential to become the first approved treatment for Netherton Syndrome. Quoin intends to self-commercialize QRX003, and its other product candidates, in the US and Europe. Furthermore, Quoin has established a global network of marketing partnerships for QRX003 spanning 60 countries. Many of these regions have early-access programs that could enable QRX003 to be made available on a named patient basis prior to formal regulatory approval.

About Netherton Syndrome
Netherton Syndrome is a rare and sometimes fatal skin disease for which there is no approved treatment, and no cure. It is caused by a mutation of the SPINK5 gene which leads to uncontrolled skin shedding, resulting in a highly porous and ineffective skin barrier. Symptoms are present at birth and include red, scaly skin. Other symptoms include outbreaks of red, circular scaly rashes, thin, fragile hair (bamboo hair), and immune reactions such as hay fever, asthma, severe pruritus (itchy skin), and eczema. Dehydration and infection are common and can be serious or fatal. Babies tend to grow slowly and have poor weight gain. Netherton Syndrome is inherited in an autosomal recessive pattern.
