VentaProst (Inhaled Epoprostenol Delivered Via Dedicated Delivery System) in Subjects With COVID-19 Requiring Mechanical Ventilation


The purpose of this study is to investigate whether inhaled epoprostenol given via a breath actuated delivery system will help improve oxygen levels and treatment outcomes in patients with COVID-19 who are on mechanical ventilation.

Detailed Description

This study will evaluate the potential therapeutic benefit of VentaProst in treating patients with COVID-19 at risk for the progression of respiratory and/ or cardiac/circulatory failure. This is an open label study of VentaProst in 10 confirmed COVID-19 patients compared to 20 COVID-19 historical control patients to assess the efficacy and safety of VentaProst given over 10 days at varying doses.


  • Drug: VentaProst (inhaled Flolan delivered via a dedicated delivery system)
    • VentaProst delivered for up to 10 days via mechanical ventilation at a dose range that may be up or down titrated to a patient’s clinical condition.

Arms, Groups and Cohorts

  • Experimental: Study Treatment
    • Up to 10 days of inhaled Flolan delivered by a breath actuated dedicated delivery system for patients with COVID-19 who are mechanically ventilated.

Clinical Trial Outcome Measures

Primary Measures

  • Reduction in Respiratory Failure
    • Time Frame: 10 days
    • Failure is defined by any one of the following: Requires VV ECMO Inability to extubate patient within 10 days or reintubation within < 24 hours Change in S/F, oxygenation index and P/F ratio ( greater than 15%) from baseline to 12 hours, Days 1, 2, 3, 4, 5, 6, 7, 8, 9 and Day 10 (or end of treatment)
  • Reduction in cardiac/circulatory Failure
    • Time Frame: 10 days
    • Failure is defined by any one of the following: Need to begin inotropic or 10% increase in current vasopressor therapy Worsening hemodynamic parameters Cardiac troponin > 20% from baseline BNP greater than 15% of baseline Need for temporary mechanical circulatory support (IABP, Impella) Requires VA ECMO

Secondary Measures

  • Improvement in Oxygenation
    • Time Frame: 10 days
    • Improvement is defined as one of the following: • Stabilization of PaO2/FIO2 >250 • Improvement in FIO2 by 50% or improvements >15% in S/F, P/F ratio from baseline at 12 hours, Day 5 and Day 10 (or end of treatment)
  • Improvement in Clinical Outcomes
    • Time Frame: 28 Days
    • Improvement is defined as one of the following: • Shorter time to extubation following the site’s extubation protocol Free from reintubation Reduction in ICU days Reduction in the number of re-admissions to the ICU due to COVID-19 within 28 days. Reduction in hospital days Mortality (28 Days) defined as Cardiopulmonary mortality or mortality from all causes.
