(Nasdaq: NRXP), a clinical-stage biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has received the Company\u2019s Abbreviated New Drug Application (ANDA) for KETAFREE\u2122, a preservative-free intravenous ketamine formulation. The acknowledgement letter states that the FDA has \u201cmade a threshold determination that this ANDA is substantially complete\u201d and issued a goal date of July 29, 2026 for completion of the final review with potential marketing approval.<\/p>\n<p>\u201cWe appreciate FDA\u2019s careful review and are pleased that it has received our application for KETAFREE\u2122, an important milestone in our effort to bring a single-patient, preservative-free presentation of ketamine to the patients and clinicians who depend on this medicine,\u201d said Jonathan Javitt, MD, MPH, Chairman and CEO of NRx Pharmaceuticals. \u201cCurrent ketamine products are typically supplied in multi-dose vials that contain a preservative called Benzethonium Chloride (BZT)\u00a0that is not recognized as safe by FDA and banned from hand cleansers and topical antiseptics.<\/p>\n<p>BZT was originally added to ketamine and other sterile injectable products in the 1970s at a time when multidose vials of medication were used to treat several patients, a practice that is no longer allowed in US healthcare facilities. BZT is no longer added to new sterile products.<\/p>\n<p>The current MAHA initiatives have called for review and removal of toxic substances from foods, drugs, and vaccines and KETAFREE\u2122, is designed to align with those priorities. \u201d KETAFREE\u2122 is is intended for all currently approved ketamine indications and is manufactured in the United States, supporting national efforts to strengthen the domestic supply of critical medicines. In awarding a Commissioner\u2019s National Priority Voucher last month to a US-based manufacturer of ketamine active pharmaceutical ingredient (API) the FDA recognized the critical strategic nature of ketamine to the nation\u2019s drug supply.<\/p>\n<p>KETAFREE\u2122 is separate from NRx\u2019s New Drug Application for NRX-100, which is being developed as an innovative drug for the treatment of suicidal depression and has received Fast Track designation from the FDA. With the KETAFREE\u2122 ANDA now received and deemed substantially complete, the next key milestone is completion of FDA review under the Generic Drug User Fee Amendments framework, with a GDUFA goal date of July 29, 2026. An approval on that timetable would potentially create meaningful 2026 approved drug sales with profitability in line with public markets analysts.<\/p>\n<p>The Company continues to advance other elements of its pipeline and its development of HOPE Therapeutics clinics, a report on which will be presented at tomorrow\u2019s Noble Securities NOBLECON conference and available on the Company\u2019s website.<\/p>\n<p>\u00a0<strong>About NRx Pharmaceuticals, Inc.<\/strong><\/p>\n<p align=\"justify\">NRx Pharmaceuticals, Inc.
