WILMINGTON, Del., Aug. 27, 2025 (GLOBE NEWSWIRE) -- NRx Pharmaceuticals, Inc. (Nasdaq:NRXP), a clinical-stage biopharmaceutical company, today announced its expanded access policy for NRX-100 (preservative-free ketamine) based on grant of designation for NRX-100 in the treatment of suicidal ideation in patients with depression, including bipolar depression.

In granting the Fast Track designation, FDA made the determination that NRX-100 has the potential to address an unmet need, based on an assessment of the preliminary data contained in the Fast Track designation request. Accordingly, NRX-100 is available for expanded access to eligible patients. More about this program can be learned from the Reagan Udall Foundation, , which works in conjunction with the FDA to provide public information on expanded access medications.

Upon physician request, NRx Pharmaceuticals may make NRX-100 available to patients when certain conditions, including the following are met:

• The patient has a serious or life-threatening illness or condition and is either no longer responsive to or not able to tolerate any approved treatment option;

• The investigational drug is in active clinical development with sufficient data available to determine an appropriate dose and schedule for the patient’s specific condition;

• A benefit-risk analysis, based on both the available clinical data as well as the requesting physician’s assessment of the individual patient’s condition and history, supports making the investigational drug available;

• Making the investigational drug available will not negatively impact or delay the conduct of clinical trials or regulatory review or approval of the investigational drug for broader patient access; and

• Adequate supply of the investigational drug is available.
  
  

“We at NRx recognize the urgent need to make NRX-100 available to patients with suicidal depression for whom approved therapies are not tolerated or effective. We look forward to participating in FDA’s expanded access program and to serving patients in need as we endeavor to Bring Hope to Life,” said Jonathan C. Javitt, MD, Chairman and CEO of NRx Pharmaceuticals.
