The Use of IV Vasoactive Intestinal Peptide (Aviptadil) in Patients With Critical COVID-19 Respiratory Failure: Results of a 60-Day Randomized Controlled Trial.
Summary
Novel Corona Virus (SARS-CoV-2) is known to cause Respiratory Failure, which is the hallmark of Acute COVID-19, as defined by the new NIH/FDA classification. Approximately 50% of those who develop Critical COVID-19 die, despite intensive care and mechanical ventilation. Patients with Critical COVID-19 and respiratory failure, currently treated with high flow nasal oxygen, non-invasive ventilation or mechanical ventilation will be treated with ZYESAMI (aviptadil), a synthetic form of Human Vasoactive Intestinal Polypeptide (VIP) plus maximal intensive care vs. placebo + maximal intensive care. Patients will be randomized to intravenous Aviptadil will receive escalating doses from 50 -150 pmol/kg/hr over 12 hours.
