NRx Pharmaceuticals, Inc. (Stock Symbol: NRXP) is a clinical-stage biopharmaceutical company developing therapeutics based on its NMDA platform for the treatment of central nervous system disorders, specifically suicidal bipolar depression, chronic pain and PTSD. NRXP is developing NRX-101, an FDA-designated investigational Breakthrough Therapy for suicidal treatment-resistant bipolar depression and chronic pain

NRXP has partnered with Alvogen Pharmaceuticals around the development and marketing of NRX-101 for the treatment of suicidal bipolar depression. NRX-101 additionally has potential to act as a non-opioid treatment for chronic pain, as well as a treatment for complicated UTI.

NRXP is working on a New Drug Application for NRX-100 (IV ketamine) in the treatment of suicidal depression, based on results of well-controlled clinical trials conducted under the auspices of the US National Institutes of Health and newly obtained data from French health authorities, licensed under a data sharing agreement. NRXP was awarded Fast Track Designation for development of ketamine (NRX-100) by the US FDA as part of a protocol to treat patients with acute suicidality.

Intravenous ketamine is widely accepted as a standard of care for acute treatment of suicidal depression, in the absence of an FDA-labeled product; the only treatment currently approved by the FDA is electroconvulsive therapy (ECT).  According to the CDC, 3.8 million Americans make a plan for suicide each year.  This represents a $3-5 billion market at expected pricing. Based on the data in the trials referenced above, the Company's regulatory counsel encouraged the Company to file an NDA for suicidal depression for NRX-100.

Patent Application Filed for NRX-100 Proprietary, Preservative Free Formulation of IV Ketamine

On May 5^th NRXP announced the filing of a patent application for NRX-100, its preservative-free intravenous ketamine formulation for the treatment of suicidal depression. The application discloses pharmaceutical compositions, methods of treatment and methods of manufacture and currently includes twenty claims. While subject to the patent review process of the US Patent and Trademark Office, if granted, the patent would provide NRX-100 exclusivity into 2045.

This patent filing builds on the NRXP recently initiated filing of an NDA for NRX-100 and its prior Fast Track Designation, with NRX-101, from the FDA. If granted, the patent will help protect the innovation behind this formulation as NRXP advances its commercialization strategy.

"We are committed to delivering safer, more effective treatments for patients with suicidal depression," said Jonathan Javitt MD MPH, CEO of NRXP. "NRX-100 eliminates the need for benzethonium chloride, a compound with well-documented safety concerns, and reflects our belief that patients in crisis deserve therapies formulated with their long-term well-being in mind. With the recent FDA fee waiver now in place, we remain on track to complete our NDA submission this quarter — a critical step toward bringing this innovation to patients in need."

FDA Award of Filing Fee Waiver for Upcoming NRX-100 (preservative free ketamine) New Drug Application to Treat Patients with Suicidal Depression

On April 30^th NRXP announced the grant of a filing fee waiver by the US Food and Drug Administration ("FDA") to exempt the Company from a $4.3 million fee to file its New Drug Application for NRX-100 (preservative-free ketamine). The waiver is granted at the discretion of the FDA to Small Business Entities and for drugs that are deemed to be necessary for Public Health. NRXP anticipates that this waiver enables the completion of its New Drug Application for NRX-100 with currently-available corporate resources. The NDA filing is anticipated by the end of the second quarter of this year (Q2 2025).

NRXP notes recent statements by the Secretary of Health and Human Services supporting the importance of psychedelic drugs to treat severe depression and PTSD. Ketamine is believed to have a beneficial effect through its role in blocking the NMDA receptor of the brain and causing increased levels of beneficial neurotransmitters in the brain, with resulting formation of new brain cell connections (synapses).
