NRx Pharmaceuticals Inc. (NASDAQ: NRXP) is advancing a two-pronged strategy to bring innovative, preservative-free ketamine therapies to market through distinct regulatory and commercial pathways. The company recently refiled an Abbreviated New Drug Application for KETAFREE(TM), a preservative-free intravenous ketamine formulation intended for all currently approved ketamine indications. This development follows the U.S. Food and Drug Administration's approval of NRx's Suitability Petition to eliminate benzethonium chloride, a chemical preservative still found in many ketamine formulations.
The removal of BZT addresses significant safety concerns, as this quaternary ammonium compound has been associated with cytotoxic and neurotoxic effects. BZT is no longer considered Generally Recognized as Safe and Effective for parenteral or topical pharmaceutical use. The European Medicines Agency has already discouraged its use in injectable drugs, and the FDA previously removed it from topical antiseptics and hand cleansers over safety concerns. By developing KETAFREE(TM), NRx aims to provide a safer and fully compliant version of ketamine for both hospital and outpatient use at a time when supply constraints and rising demand have challenged healthcare providers.
Alongside the ANDA pathway for KETAFREE(TM), NRx is advancing NRX-100, a separate preservative-free ketamine product, under a New Drug Application for the treatment of suicidal depression, including bipolar depression. The formulation has been granted Fast Track Designation by the FDA, positioning it for potential expedited review. NRx has recently initiated a New Drug Application filing for NRX-100 for the treatment of suicidal depression based on results of well-controlled clinical trials conducted under the auspices of the U.S. National Institutes of Health and newly obtained data from French health authorities, licensed under a data sharing agreement.
The company's dual approach represents a significant advancement in ketamine therapy safety and accessibility. The elimination of potentially harmful preservatives addresses long-standing safety concerns while expanding treatment options for serious mental health conditions. This development comes as ketamine therapies gain broader acceptance for treatment-resistant depression and other conditions, making safety improvements particularly timely.

NRx Pharmaceuticals 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. The company is also developing NRX-101, an FDA-designated investigational Breakthrough Therapy for suicidal treatment-resistant bipolar depression and chronic pain, with plans to file an NDA for Accelerated Approval for NRX-101 in patients with bipolar depression and suicidality or akathisia.
