As a Nasdaq-listed company, NRx will deploy public capital to continue development of two investigational medicines: ZYESAMI™, (Aviptadil acetate) the first FDA Fast Track-designated investigational medicine, being studied in critically-ill patients with COVID-19 induced respiratory failure, and NRX-101 (a combination drug therapy of D-cycloserine and lurasidone), the first investigational medicine to receive FDA Breakthrough Therapy Designation for patients with suicidal bipolar depression. ZYESAMI™ has demonstrated a statistically significant increase in the likelihood of survival and recovery from respiratory failure in a phase 2b/3 trial (co-funded with Relief Therapeutics (SIX:RLF,OTCBB:RLFTF) of critically-ill patients with COVID-19.1,2 These advantages were previously reported in an open label trial of critically-ill patients at the Houston Methodist Hospital.3 The company expects to seek Emergency Use Authorization of ZYESAMI™ from the FDA in May 2021.

NRX-101 is based on the inventions and innovation of Prof. Daniel Javitt, MD, PHD, who first explained the impact of the brain’s NMDA receptor in schizophrenia and other psychiatric diseases. NRX-101 has demonstrated a statistically-significant advantage in maintaining remission from depression after initial treatment with ketamine in a phase 2 study.4 Currently, the only FDA-approved treatment for suicidal bipolar depression is electroshock therapy.

Both investigational medicines (ZYESAMI™ and NRX-101) are now in FDA-approved phase 3 clinical trials. The trial of ZYESAMI™ is being conducted by the National Institutes of Health (ACTIV3b/TESICO) at leading medical centers around the world.5 A second trial is being conducted on the I-SPY platform with the support of the Biomedical Advanced Research Development Authority (BARDA) of the US Department of Health and Human Services. The trial of NRX-101 is being led by investigators at Harvard/Mass General, University of Alabama Birmingham, and Baylor College of Medicine.6
