Press Releases

• The June 2024 meeting of the American Society for Clinical Psychopharmacology (ASCP) focused heavily on increasing use of intravenous ketamine and intranasal S-ketamine as the emerging standard of care for treating severe depression and suicidality
• Presenters from 3 open label studies at the ASCP suggested that intravenous ketamine is at least equivalent and may have advantages over intranasal S-ketamine
• NRx Pharmaceuticals has now reached the 9-month stability point with its ketamine formulation (NRX-100) and has initiated 3 manufacturing lots for future drug release. Nonclinical safety for short term use of NRX-100 has recently been published and submitted to FDA
• FDA leadership, in public comments at ASCP, focused on the need for nonclinical safety data for intravenous ketamine as a condition of ketamine approval
• The short-term need for intravenous ketamine as an already-approved, schedule 3 drug, is heightened by recent regulatory decisions that may delay the path of potent, schedule 1 psychedelic drugs that may require more complicated clinical trial designs.

RADNOR, Pa., June 10, 2024 /PRNewswire/ -- NRx Pharmaceuticals, Inc. (Nasdaq: NRXP) ("NRx Pharmaceuticals", the "Company"), a clinical-stage biopharmaceutical company, today announced that the Company posted a new Shareholder Update Letter on its website NRx Shareholder Update and further invites interested parties to subscribe to their email alert service to stay up to date on company's progress here: NRx Email Alerts . (Note: not all updates will be included in a Press Release in the future).

Today's update highlights potential implications of the Company's recent activities at the annual meeting of the American Society of Clinical Psychopharmacology.  The key points include:

• Intravenous and intranasal ketamine were highlighted as emerging standards of care for severe depression and suicidality
• Planned NDA filing for NRX-100, our preservative free IV ketamine, for Suicidal Depression in 2024, is based on well controlled trials against both placebo and active comparator. Fast Track Designation was previously granted
• An independent FDA advisory panel recently voted against MDMA, a potent, class I psychedelic, refocusing attention on already-approved Schedule 3 drugs such as ketamine for treatment of suicidal depression.  The FDA panel and emerging guidance highlights the complexity of clinical trials of DEA Schedule 1 hallucinogens that do not have already-approved human uses
• NRx anticipates that an important issue for longer term use of ketamine in depression will be the current multidose vial presentation that contains potentially toxic preservatives previously acceptable for one time use but less suitable for repeated use. NRX-100 is planned as a single-dose, preservative-free medication.

Please subscribe to the Company's email for future updates.  NRX Email Alerts Not all of these will be the subject of a Press Release in the future.
