NRx Defense Systems, an NRx Company (Nasdaq:NRXP) Awarded $11 Million Dollar DARPA Prime Contract to Evaluate Robotic Magnetic Stimulation in conjunction with NRX-101 for Treatment of Resistant Depression
The award funds evaluation of a single-day treatment approach, with patient enrollment set to begin in the FDA-approved trial.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
NRx Pharmaceuticals (NRXP) subsidiary NRx Defense Systems received an initial DARPA prime contract of $11,177,757.27 to evaluate a depression treatment. The FDA-approved SPARC-TMS trial will begin enrolling patients to test whether a single day of transcranial magnetic stimulation (TMS), combined with investigational drug NRX-101, can effectively treat major depressive disorder.
The trial will run at Harvard Medical School’s McLean Hospital, Arizona State University and HOPE Therapeutics, with plans to expand to military hospitals. Its foundation includes a completed DARPA-funded randomized trial and published real-world findings of 91% treatment response and 69% remission three months after traditional TMS plus D-cycloserine. NRx says SPARC-TMS could serve as an FDA registration study for NRX-101 with TMS in treatment-resistant depression if those results are replicated.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

- DARPA states that the program, if successful, will fundamentally change the Standard of Care for Treatment Resistant Depression. The Military has recognized that current treatments for depression are not deployable in operational military settings.
- The SPARC-TMS Single Day treatment protocol, which involves the use of Robotic Neuronavigated Transcranial Magnetic Stimulation (TMS) augmented by NRx’s neuroplastic investigational drug NRX-101, is based on a recently completed randomized-controlled trial funded by DARPA and published real world findings of
91% treatment response and69% remission at 3 months post treatment with traditional TMS + D-cycloserine (an active ingredient of NRX-101). - If the above results are replicated in the SPARC-TMS trial, it has the potential to serve as an FDA registration study for approval of NRX-101 in conjunction with TMS for people with Treatment Resistant Depression
- NRx Defense Systems is partnered with HOPE Therapeutics (an NRx sister company), Harvard Medical School’s McLean Hospital, Arizona State University, Zeta Surgical Systems, and Neurocare of America.
- Plans are underway to expand the SPARC-TMS trial to leading military hospitals.
- NRx Defense systems is led by a team of former senior military officers and former employees of the Office of the Secretary of Defense with advanced degrees in medicine, psychology, and data science.
MIAMI, Sept. 30, 2026 (GLOBE NEWSWIRE) -- NRx Defense Systems, (“NRx Defense”, “NRXD” or “Company” an NRx Pharmaceuticals, Inc. (Nasdaq: NRXP) subsidiary company, today announced the award of an initial
The SPARC-TMS trial will be conducted at Harvard Medical School’s McLean Hospital, Arizona State University, and HOPE Therapeutics. Several leading military hospitals will also be affiliated with the study.
The focus of SPARC-TMS is to test whether an entire course of TMS delivered in a single day can effectively treat major depressive disorder when combined with mechanism-guided pharmacologic augmentation with NRX-101. TMS is thought to exert its therapeutic effects primarily through synaptic plasticity – the cellular basis of learning and memory. Synaptic plasticity is mediated by NMDA receptors. NRX-101 combines two drugs that may enhance NMDA receptor function through complementary mechanisms: d-cycloserine, an NMDA receptor partial agonist, and lurasidone, which has been shown to increase NMDA receptor expression through 5-HT7 antagonism. The treatment to be tested requires a single day in an outpatient clinic, involves no psychedelic experience or intense supervision, no anesthesia, and can be delivered by a robotic targeting system originally developed for neurosurgery with precision of 1mm or less. The preamble to the DARPA contract states that,
Current treatments for Treatment Resistant Depression … require weeks of daily outpatient treatment, have modest response rates of
NRX-101, the investigational drug to be tested in this trial was originally conceived by NRx Pharmaceuticals as a Breakthrough therapy drug for treatment of suicidal bipolar depression and so far has demonstrated a reduction in both suicidality and akathisia compared to lurasidone a standard of care drug approved by the FDA in bipolar depression. The SPARC-TMS trial has the potential to serve as an FDA registration study for the use of NRX-101 in conjunction with TMS for people with Treatment Resistant Depression. a far larger population of patients, estimated at 8.9 million American adults with an estimated
Military personnel, veterans, and first responders are known to have substantially elevated rates of depression and suicidality, compared to civilians, an issue that has been addressed by the President of the United States, multiple cabinet-level officials, and numerous public service organizations.
The SPARC-TMS project is based on multiple years of research led by NRXD’s Chief Medical Innovation Officer, Prof. Joshua Brown, MD, PhD, who has pioneered the understanding of the interplay between small molecule drugs for improving neuroplasticity and TMS. Prof. Daniel Javitt, NRx’s co-founder originally reported the role of the NMDA receptor in psychiatric disease in 1987.
NRx Defense Systems was founded as a subsidiary of NRx Pharmaceuticals by Prof. Jonathan Javitt, MD, MPH, CEO and founder of NRXP, Prof. Joshua Brown, MD, PhD, and Dr. Dennis McBride, PhD, (CAPT Medical Service Corps US Navy, Retired, former Senior Executive Leader National Defense University and Office of the Secretary of Defense). Dr. McBride served multiple tours of duty, including scientific leadership roles at six military laboratories and as the first behavioral neuroscientist to be named a DARPA program manager during his highly-decorated Navy career. Their team is augmented by Dr. Martin Goodwin, PhD, a psychologist and data scientist who has just completed a decorated tour of duty as District Commodore for the US Coast Guard Auxiliary.
“I am delighted to unite with my former colleagues at DARPA to reinvent the paradigm for treating depression and suicidality for all Americans,” said Dr. McBride, “During my time at DARPA we advanced cognitive-based artificial intelligence with the ambition to use advanced computational techniques to solve humanity’s greatest challenges. It is inspiring to be part of this AI-empowered mission because it will save countless lives.”
“The chance to see fundamental research mature from my laboratory to a technology that has the potential to save lives and end suffering is the dream of any physician scientist,” said Dr. Brown, “while success is far from guaranteed in any clinical trial, DARPA has a long track record of supporting pioneering efforts with far-reaching impact, and their support gives us the strongest possible foundation for success.

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
How much is the DARPA contract awarded to NRx Defense Systems?
NRx Defense Systems received an initial DARPA prime contract of $11,177,757.27. The contract supports SPARC-TMS, which will evaluate single-day transcranial magnetic stimulation combined with NRX-101 for depression.
What will NRx’s SPARC-TMS depression trial test?
SPARC-TMS will test whether an entire course of TMS delivered in one day, combined with NRX-101, can effectively treat major depressive disorder. The trial has FDA approval and will now begin enrolling patients.
What drugs are combined in NRX-101 for the SPARC-TMS trial?
NRX-101 combines D-cycloserine and lurasidone. NRx describes them as potentially enhancing NMDA receptor function through complementary mechanisms: D-cycloserine partially activates the receptor, while lurasidone has been shown to increase its expression through blocking the 5-HT7 receptor.
