NeuroRx, Inc. today reports 60-day results of the Phase 2b/3 trial of intravenously-administered ZYESAMI™ (aviptadil acetate) for the treatment of respiratory failure in critically-ill patients with COVID-19, which is being developed in collaboration with Relief Therapeutics Holding AG (SIX:RLF, OTCQB:RLFTF). Across all patients and sites, ZYESAMI™ met the primary endpoint for successful recovery from respiratory failure at days 28 (P = .014) and 60 (P = .013) and also demonstrated a meaningful benefit in survival (P = < .001) after controlling for ventilation status and treatment site.


In addition to the robust overall significance across all 196 treated patients at all 10 clinical sites, the prespecified analysis of recovery from respiratory failure is clinically and statistically significant in the 127 patients treated by High Flow Nasal Cannula (HFNC) (P = .02), compared to those treated with mechanical or non-invasive ventilation at tertiary care hospitals. In this group, ZYESAMI™ patients had a 71% chance of successful recovery by day 28 vs. 48% in the placebo group (P = .017) and a 75% rate of successful recovery by day 60 vs. 55% in the placebo group (P = .036). Eighty-four percent (84%) of HFNC patients treated at tertiary medical centers with ZYESAMI™ survived to day 60 compared with 60% of those treated with placebo (P = .007).
