Item 7.01. Regulation FD Disclosure.

 

On October 21, 2025, Quoin Pharmaceuticals Ltd. (the “Company” or “Quoin”) issued a press release announcing that the U.S. Food and Drug Administration (the “FDA”) has granted Orphan Drug Designation to the Company’s lead product candidate, QRX003, for the treatment of Netherton Syndrome. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K (the “Report”) and is incorporated by reference herein.

 

The information in this Item 7.01 and Exhibit 99.1 attached hereto are furnished and shall not be deemed to be “filed” with the Securities and Exchange Commission (the “SEC”) for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

 

Item 8.01. Other Events.

 

On October 21, 2025, the Company announced that the FDA has granted Orphan Drug Designation to the Company’s lead product candidate, QRX003, for the treatment of Netherton Syndrome. The designation follows previously granted Orphan Drug Designation by the European Medicines Agency (the “EMA”) in May 2025.

 

The FDA’s Orphan Drug Designation program provides orphan status to therapies intended for the treatment, diagnosis, or prevention of rare diseases that affect fewer than 200,000 people in the United States. This designation provides certain benefits, including tax credits for qualified clinical testing, waiver or partial payment of FDA application fees and seven years of market exclusivity, if approved. QRX003 is on track to potentially become the first approved treatment for Netherton Syndrome.

 

QRX003 lotion (4%) is being evaluated in two late-stage whole body pivotal clinical trials for Netherton Syndrome. Enrollment in both pivotal studies is expected to be completed in the first quarter of 2026, top-line data is anticipated in the second half of 2026, and a new drug application (“NDA”) submission is planned later in the year.

 

Cautionary Note Regarding Forward Looking Statements

 

The Company cautions that statements in this Report that are not descriptions of historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words referencing future events or circumstances, such as “expect,” “intend,” “hope,” “plan,” “potential,” “anticipate,” “look forward,” “believe,” “may,” and “will,” among others. All statements that reflect the Company’s expectations, assumptions, projections, beliefs, or opinions about the future, other than statements of historical fact, are forward-looking statements, including, without limitation, statements relating to: QRX003 being on track to potentially become the first approved treatment for Netherton Syndrome, the progress of the Company’s clinical trials, and the timing of trial results and regulatory submissions. Because such statements are subject to risks and uncertainties, actual results may differ materially from those expressed or implied by such forward-looking statements. These forward-looking statements are based upon the Company’s current expectations and involve assumptions that may never materialize or may prove to be incorrect. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements as a result of various risks and uncertainties including, but not limited to, the timing of the Company’s clinical studies may be delayed and other factors discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 and in other filings the Company has made and may make with the SEC in the future. One should not place undue reliance on these forward-looking statements, which speak only as of the date on which they were made. The Company undertakes no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they were made, except as may be required by law.
