In the two Phase 2 trials, PUL-042 was evaluated in one trial as preemptive treatment in patients with early, symptomatic infection and in a second trial in the prophylactic settings in subjects with known exposure to SARS-CoV-2. The Phase 2 studies of PUL-042 for COVID-19 are funded in part with federal funds from the DOD’s Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense (JPEO-CBRND), through the U.S. Army Contracting Command - New Jersey, under an Other Transaction Agreement (W15QKN-16-9-1002, Project #MCDC 2006-002) awarded to the Medical CBRN Defense Consortium and Pulmotect, Inc.
