NRx Pharmaceuticals, Inc. (NRXP) reports that the FDA Office of Generic Drugs has reclassified an amendment to its Abbreviated New Drug Application (ANDA) for preservative-free intravenous ketamine from a Major Amendment to a Minor Amendment.

The company highlights this as an advance in the approval process for its preservative-free ketamine, which it describes as a strategic product intended to address drug shortages and support treatment of suicidal ideation in depression, including bipolar depression.

NRx Pharmaceuticals, Inc. reported financial results for the quarter and six months ended June 30, 2026, alongside a significant corporate update. For the six-month period, the company reported a net loss of $18.0 million compared with $23.1 million in 2025, while net operating loss increased to $11.3 million from $7.6 million due to higher R&D and commercial readiness expenses. Cash and cash equivalents rose to $26.7 million as of June 30, 2026 from $7.8 million at December 31, 2025, primarily driven by a public equity offering with more than $22 million in gross proceeds, supporting at least one year of operations.
The company advanced its ANDA for preservative-free ketamine, with the FDA citing no major drug or manufacturing deficiencies and only one container-related issue, which has been addressed. NRx is manufacturing 5 million units of launch stock with plans for 1 million units per month post-launch, targeting 2026 approval and commercialization. The NDA for NRX-100 is being finalized following federal support for using Real World Evidence, including data from 65,000 patients, with an approval goal in 2027. NRx was also selected as Prime Contractor for the DARPA SPARC-TMS phase 3 trial of NRX-101, potentially expanding its addressable depression market to more than 15 million Americans, and invested in Geneuro, Inc., gaining two clinical-stage monoclonal antibodies for ALS and other neurodegenerative and autoimmune conditions.
NRx Pharmaceuticals, Inc. reported results for the quarter ended June 30, 2026 as a clinical-stage biopharmaceutical company now also generating clinic revenue through its HOPE subsidiary. Net patient service revenue was $1.1 million for the quarter and $2.2 million for the first six months of 2026, compared with none in 2025, reflecting acquired Florida behavioral health clinics.
The company recorded a six‑month net loss of $17.9 million and used $13.2 million of cash in operating activities. Cash and cash equivalents increased to $26.7 million as of June 30, 2026 from $7.8 million at year‑end, driven by $11.8 million raised via at‑the‑market issuances and a $20.7 million underwritten equity offering. Total assets were $34.2 million, offset by $34.3 million of liabilities, including $18.6 million of warrant liabilities and a $5.8 million refund liability to Alvogen.
Stockholders’ deficit narrowed to $0.2 million. Management disclosed that recurring losses, a $4.7 million working capital deficit and funding uncertainties raise substantial doubt about the ability to continue as a going concern, despite current cash projected to support drug development into early 2027.
NRx Pharmaceuticals is updating investors on U.S. FDA review of its Abbreviated New Drug Application (ANDA) for preservative‑free ketamine. On July 30, 2026 the FDA reported no major deficiencies related to the drug components, but requested a label update to match the reference drug Ketalar and identified a single major deficiency concerning the twist‑off cap of the luer lock vial, which affects the container closure.
NRx highlighted performance testing on 3,500 vials from seven manufacturing batches and real‑world experience with 11.9 million doses of similar products using the same vial design, without complaints, returns, or recalls. After an August 6, 2026 clarification meeting, the FDA asked for formal manufacturer certifications that this product is made on the same lines and with the same materials as three approved ANDA products, then agreed to immediately reinitiate review focused on this packaging issue and to complete it in the shortest‑possible review cycle. Management notes ketamine’s presence on the FDA drug shortage list and expresses optimism about resolving the packaging concern and achieving initial commercial sales in 2026, while acknowledging that regulatory outcomes cannot be assured.
NRx Pharmaceuticals, Inc., through its Florida-based subsidiary NRx Defense Systems, Inc., received a July 21, 2026 letter from the Defense Advanced Research Projects Agency (DARPA) Defense Sciences Office stating that its proposal for a clinical trial titled Synaptic Plasticity Augmented Rapid Circuit Stimulation (SPARC-TMS) has been selected for negotiation of a potential award.
The SPARC-TMS study uses robotic-enabled Transcranial Magnetic Stimulation combined with NRX-101 (D-cycloserine/lurasidone) to evaluate remission from depression. The protocol is approved by the FDA as a phase 2/3 trial and is listed on ClinicalTrials.gov as NCT07227103. Planned sites include Harvard McLean Hospital, HOPE Therapeutics clinics, and military treatment facilities such as Walter Reed National Military Medical Center. NRX-101 is patented by the company and previously received FDA Breakthrough Therapy Designation. DARPA’s selection is only for contract negotiations and is not an award, funding commitment, or authorization to incur costs; any award would depend on successfully negotiating definitive terms.
