Quantum Leap Healthcare Collaborative (QLHC) announced that the nebulized form of NRx Pharmaceuticals Inc's (NASDAQ:NRXP) Zyesami (Aviptadil) in the I-SPY COVID Trial of critical patients had been stopped. 

• The I-SPY COVID Trial is a phase 2 trial designed to rapidly screen potential agents that could substantially improve treatment for severely and critically ill COVID-19 patients. QLHC is the sponsor of the I-SPY COVID TRIAL. 
• The trial o identify those agents that could potentially reduce the time to recovery by approximately 50% or the risk of mortality in critically ill COVID-19 patients.
• The data suggested a low probability that adding a dose of nebulized Aviptadil to backbone therapy via mouthpiece administration would improve outcomes. 
• At the time of discontinuation, the hazard ratio for recovery favored placebo.
• The findings in the current I-SPY study may be due to the difficulty of effectively delivering nebulized medications via mouthpiece to critically ill patients when they are on high flow oxygen or nebulized into the breathing circuit for mechanically ventilated patients. 
• The intravenous form of Zyesami is currently being tested in the ACTIV-3b Phase 3 trial being conducted by the National Institutes of Health, a separate clinical trial of critically ill patients, which continues enrolling.
