Study Description
Brief 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 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.
Detailed Description:

Acute Lung Injury, which triggers Critical COVID-19 is a known lethal complication of Corona Virus (SARS-CoV-2) infection. Conventional medical therapy, including intensive care and respiratory support is associated with an 80% mortality. Aviptadil, a synthetic form of Human Vasoactive Intestinal Polypeptide (VIP) has been awarded FDA Orphan Drug Designation for the treatment of ARDS and admitted to the FDA CoronaVirus Technology Accelerator Program.

VIP binds to VPAC1 receptors on the pulmonary Alveolar Type II (ATII) cell. ATII cells comprise only 5% of lung epithelial cells but are critical for oxygen transfer, surfactant production, and maintenance of Alveolar Type 1 cells. 70% of VIP binds to this receptor. The Type II cell is also the cell selectively attacked by the SARS-CoV-2 virus via the ACE2 surface receptor.

Nonclinical studies demonstrate that VIP is highly concentrated in the lung and specifically bound to the ATII cell, where it prevents NMDA-induced caspase-3 activation in the lung, inhibits IL6 and TNFa production, protects against HCl-induced pulmonary edema, and upregulates surfactant production, These and other effects have been observed in numerous animal model systems of lung injury in mice, rats, guinea pigs, sheep, swine, and dogs. In these models, Aviptadil restores barrier function at the endothelial/alveolar interface and thereby protects the lung and other organs from failure.

Aviptadil ihas a demonstrated 20 year history of safety in phase 2 trials for Sarcoid, Pulmonary Fibrosis, Bronchospasm, and a phase I trial in ARDS. In that phase I trial, 8 patients with severe ARDS on mechanical ventilation were treated with ascending doses of VIP. Seven of the 8 patients were successfully extubated and were alive at the five day timepoint. Six left the hospital and one died of an unrelated cardiac event.

Five phase 2 trials of aviptadil have been conducted under European regulatory authority. Numerous healthy volunteer studies have shown that i.v. infusion of Aviptadil is well tolerated with few adverse effects including alterations in blood pressure, heart rate, or ECG. In addition to published studies of human use, Aviptadil has been used on a compounded basis in certain ICUs for many years in the belief that it preserves life and restores function in pulmonary hypertension, ARDS, and Acute Lung Injury (ALI).

In this study, patients who are hospitalized for Critical COVID-19 infection with respiratory failure will be randomly allocated to Aviptadil administered by intravenous infusion in addition to maximal intensive care vs. maximal intensive care alone. Primary endpoints will be improvement in blood oxygenation and mortality.
