NRx Pharmaceuticals Provides Update on Breakthrough Therapy Designation (BTD) Request for ZYESAMI® (aviptadil)

RADNOR, Pa., June 10, 2022 /PRNewswire/ — NRx Pharmaceuticals, Inc. (Nasdaq: NRXP, NRx Pharmaceuticals), (“NRXP” or the “Company”), a clinical-stage biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) denied the Breakthrough Therapy designation (BTD) request for ZYESAMI® (aviptadil) and emphasized its focus on the company’s NRX-101 BTD compound for Bipolar Depression associated with Suicidality.  The request for BTD was submitted based on the positive finding of a post-hoc subgroup analysis of patients who in addition to Aviptadil or placebo were also treated with Remdesivir and whose respiratory failure due to Critical COVID-19 continued to progress.

“Although we are disappointed about FDA’s decision, as recently announced, our strategic focus has already shifted to the advancement of our Breakthrough Therapy designation drug NRX-101.  We expect topline data for our ongoing Phase II study of NRX-101 in patients with bipolar depression with sub-acute suicidal ideation (SSIB) by the end of the year. COVID-19, unfortunately, has also created a mental health crisis, including depression and suicides. Our commitment to helping patients with high unmet needs remains at the core of our work,” said Robert Besthof, interim CEO of NRx Pharmaceuticals. 

“Given ZYESAMI’s mechanism and its well characterized safety profile, NRx Pharmaceuticals will further evaluate the options for its use in other high unmet pulmonary as well as other non-pulmonary indications.”
