NRx Pharmaceuticals, Inc. (Nasdaq: 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.
Filing of Commissioner’s National Priority Voucher Application for Intravenous Ketamine (NRX-100)
On June 23rd NRXP announced filing for the newly-announced FDA Commissioner’s National Priority Voucher program on behalf of NRX-100, its patent-pending, preservative-free formulation of ketamine for intravenous use.
On June 17, 2025, FDA Commissioner Marty Makary, MD, MPH announced a new approval pathway, the Commissioner’s National Priority Voucher (CPNV)1, for approval of drugs to enhance the health interests of Americans. Previously, on May 25 he identified psychedelic drugs for treatment of suicidal depression and PTSD as a national priority.2 The new voucher may be redeemed by drug developers to participate in a Commissioner-led program that shortens its review time from approximately 10-12 months to 1-2 months following a sponsor’s final drug application submission.
To qualify for the CNPV, sponsors must submit the chemistry, manufacturing, controls (CMC) portion of the application and the draft labeling at least 60 days before submitting the final application. NRXP has already submitted the CMC portion for NRX-100 and received FDA feedback.
Concurrent with the CNPV process, NRXP is preparing a citizen petition to seek withdrawal of preservative-containing forms of ketamine, based on the toxicity associated with the benzethonium chloride preservative used in the historic formulation. NRXP has also filed a patent on its preservative-free manufacturing process. Approval of either the citizen petition, or the patent, would be expected to enable NRXP to gain market share in the current $750 million generic ketamine market that is forecast to reach $3-5 billion annually by 2033, in addition to a share of the market already established for ketamine products for treating depression.
Strategic Investor Relations Partnership with astr partners
On June 16th NRXP announced a strategic investor relations partnership with astr partners, a boutique investor relations and capital advisory firm focused on the life sciences sector.
astr partners will work with the NRXP and HOPE subsidiary executive teams to execute a comprehensive investor relations program that includes investor targeting, message development, earnings preparation, conference support, and proactive investor engagement.
Abbreviated New Drug Application (ANDA) for Preservative-Free IV Ketamine
On June 5th NRXP announced the transmission of its Abbreviated New Drug Application (ANDA) for electronic filing to the U.S. Food and Drug Administration (FDA) for NRX-100, its preservative-free IV ketamine formulation, for use in all existing approved indications such as anesthesia and pain management.
NRXP anticipates filing a citizen’s petition with the FDA to remove benzethonium chloride, a known neurotoxic and cytotoxic substance, from presentations of ketamine intended for intravenous use. NRXP believes that the preservative-free feature of NRX-100 will be deemed of benefit to patients because of the known toxicity of closely related benzalkonium chloride in current drug products. Preservatives were originally added to sterile injectable products in an era when a single vial of medication was used to treat multiple patients, a practice no longer allowed in US hospitals. NRXP has demonstrated that there is no need for such preservatives to maintain stability and sterility in ketamine presentations intended for single-patient use. Should the citizen’s petition be granted, all formulations of ketamine sold in the US could face a regulatory requirement to be preservative free.
$7.8 Million Debt Financing to Fuel NRXP HOPE Clinic Acquisitions
On May 15th NRXP announced signing of a term sheet with Universal Capital, LLC to provide $7.8 million in acquisition capital to initiate subsidiary HOPE’s planned national rollup of interventional psychiatry clinics, commencing with previously-announced acquisitions of Dura Medical, Kadima, and NeuroSpa. Together with proceeds of a previously announced strategic investment, this financing is anticipated to provide $10.3 million in acquisition capital.
HOPE’s three initial acquisitions represent best-in-class clinics that offer neuroplastic treatments including NRXP ketamine and transcranial magnetic stimulation (TMS) to treat patients with severe depression, PTSD, and related central nervous system conditions. Neuroplastic treatments represent a rapidly emerging class of interventions that cause the growth of new connections (synapses) between brain cells that have been shown in multiple clinical trials to relieve symptoms of depression and suicidality. The FDA has approved TMS devices for a number of indications and has approved a nasal form of ketamine for treatment resistant depression. HOPE’s parent company, NRXP, is currently applying to the FDA for approval of intravenous preservative-free ketamine to treat suicidal depression.
Agreement to Purchase Kadima Neuropsychiatry Institute; Foundational Acquisition for the NRXP HOPE Network of Interventional Psychiatry Clinics
On May 13th NRXP announced signing of a definitive agreement to purchase the Kadima Neuropsychiatry Institute. Kadima is expected to serve as the clinical model for treatment offerings in NRXP HOPE-acquired clinics and is expected to continue its role as a leading investigative site for research into neuroplastic therapies including psychedelic medications, transcranial magnetic stimulation (TMS), and hyperbaric therapy.
Kadima is one of California’s flagship interventional psychiatry clinics and was among the first to bring ketamine treatment for central nervous system (CNS) disorders out of academic research settings and into clinical practice. The clinic offers a full range of treatments for suicidal depression, PTSD and other CNS disorders. Further, Kadima and David Feifel, MD PhD, Founder and Medical Director of Kadima, have served as leaders in clinical trial work on emerging therapies in CNS for top companies in the industry. Importantly, the clinic is profitable and is forecast to continue growth going forward. Dr. Feifel will join NRXP HOPE as its first Chief Medical Innovation Officer upon closing of the acquisition.
