Quoin Pharmaceuticals Provides Corporate Update and Announces First Quarter 2025 Financial Results

Continued Progress in Ongoing Late-Stage Netherton Syndrome Studies

Announced Positive Clinical Data for Adult and Pediatric Netherton Patients

Provided Clear Visual Evidence of QRX003 Mechanism of Action

Patent Portfolio Expanded to Support Pipeline Growth

Launch of NETHERTON NOW Advocacy Initiative

/EIN News/ -- ASHBURN, Va., May 13, 2025 (GLOBE NEWSWIRE) -- Quoin Pharmaceuticals Ltd. (NASDAQ: QNRX) (the “Company” or “Quoin”), a late clinical-stage, specialty pharmaceutical company focused on developing and commercializing novel treatments for rare and orphan diseases, today provides a business update and announces financial results for the quarter ended March 31, 2025.

Quoin CEO Dr. Michael Myers said, “The first quarter of 2025 has seen continued momentum across all aspects of our business. We reported compelling data from multiple QRX003 studies in Netherton Syndrome, including clear visual evidence of almost complete skin healing and reduction or, in some cases, the elimination of pruritus allowing the patient to experience zero nightly sleep disturbance for the first time in their life. Whole-body treatment with QRX003 has also enabled the pediatric patient to discontinue previously required medications including antibiotics, antihistamines, antivirals and glucocorticoids. We also announced positive data from our open-label study that demonstrated clear visual evidence of almost complete skin healing compared to baseline. Importantly, we also reported that a full and rapid reversal of all clinical benefits from QRX003 treatment occurs following discontinuation of treatment. This result provides clear support that QRX003 acts as a broad-spectrum serine protease inhibitor targeting the skin kallikreins and performs the function of the missing LEKTI protein by restoring the natural balance of skin replenishment and skin shedding. Alongside this clinical progress, we expanded our patent portfolio with new filings covering novel formulations targeting several rare skin diseases, including our new development programs for microcystic lymphatic malformations, venous malformations and angiofibromas. We also launched NETHERTON NOW, our multi-faceted awareness initiative to support and engage with the Netherton community, advocacy groups, treating physicians, and policy and lawmakers. In short, this has been a busy but highly productive start to 2025, and we are very excited by our continued progress and remain focused on delivering the first approved treatment for this devastating disease”

Q1 2025 Corporate Highlights
Over the past three months, Quoin achieved a number of significant corporate milestones and highlights:

Jan. 6, 2025
Quoin announced 12-week data from the first adult subject dosed twice daily with QRX003 in the open-label study, showing improvement across all endpoints and sustained benefit with no safety concerns.

Jan. 14, 2025
Interim results from the pediatric Investigator Study showed the subject improved from “Severe” to “Mild” on the Investigator’s Global Assessment (IGA) after six weeks of treatment, prompting a transition to whole-body dosing.

Jan. 23, 2025
Post-treatment follow-up data showed complete reversal of clinical gains four weeks after QRX003 was discontinued, supporting the need for chronic treatment and affirming the drug’s mechanism of action.

Feb. 4, 2025
Quoin launched its NETHERTON NOW awareness campaign, including a stand-alone website and patient-focused media hub to raise visibility around NS and support the community.

Feb. 27, 2025
Groundbreaking results from the first pediatric subject to receive whole-body QRX003 dosing revealed rapid and profound clinical benefit within two weeks, including the elimination of pruritus and discontinuation of prior medications.

March 4, 2025
U.S. and international patents were filed for topical rapamycin formulations targeting a number of rare skin diseases.

March 25, 2025
Quoin filed a new U.S. patent application for novel formulations of QRX003 and related compounds, potentially extending IP protection through 2045 across multiple rare disease indications.

Financial Highlights

Cash Position:
Quoin had approximately $11.6 million in cash, cash equivalents, and marketable securities as of March 31, 2025. The Company believes this capital will support operations into the first quarter of 2026.

Net Loss:
For the quarter ended March 31, 2025, Quoin reported a net loss of approximately $3.8 million, compared to a net loss of approximately $2.3 million for the same period in 2024.

Looking Ahead
Quoin continues to advance its active clinical studies of QRX003 in NS, with additional pediatric and adult sites preparing to launch internationally. A newly FDA-cleared study, led by Dr. Amy Paller at Northwestern University, will evaluate whole-body application of QRX003 in up to eight to twelve patients. Designed to simulate real-world use of QRX003 once approved, this study will generate what will potentially be the most extensive clinical data set ever compiled for Netherton Syndrome.
