Trial Outcomes & Findings for VentaProst Versus Conventionally-Administered Aerosolized Epoprostenol in Patients Undergoing Cardiac Surgery With CPB (NCT NCT03122730)

NCT ID: NCT03122730

Last Updated: 2025-07-31

Results Overview

The primary goal was to establish the dose of VentaProst necessary to achieve a PD response comparable to the standard of care. The first dose of VentaProst tested, 17 ng/kg/min, achieved the dose equivalency.

Recruitment status

SECONDARY outcome

Timeframe: Pharmacodynamic changes will be measured during surgery (Day 1), post-surgery (Day 1), and from start of study treatment (Day 1) through study completion (up to 30 days)

Population: Per protocol population (Part II)

Calculate vascular resistance indicators for CI and CO, and PAPi at each dose level. Identify the VP dose where mPAP, VR(CO), VR(CI), CVP are lowest, and CI/CO are highest. Compare in a narrative to the selected VP optimal dose by the Investigator by individual patient.
