Infusion of Prostacyclin (Iloprost) vs Placebo for 72-hours in Patients With Septic Shock Suffering From Organ Failure

Resumen breve

The purpose of this trial is to investigate the efficacy and safety of continuous intravenous administration of low dose iloprost versus placebo for 72-hours, in up to a total of 380 patients with septic shock suffering from organ failure.

The study hypothesis is that iloprost may be beneficial as an endothelial rescue treatment as it is anticipated to deactivate the endothelium and restore vascular integrity in septic shock patients suffering from organ failure caused by endothelial breakdown, ultimately improving survival.

Descripción detallada

Patients with the most severe type of sepsis, those with septic shock have a mortality rate between 30% to 45% due to multiple organ failure. The poor outcome of shocked patients, and especially those with sepsis, may by related to microvascular endothelial dysfunction. Evidence support that iloprost infusion significantly improved endothelial function and integrity,

The main objective in this trial is to investigate whether continuous infusion of lov dose iloprost at a dose of 1 ng/kg/min for 72-hours is safe and significantly reduce organ failure score in the intensive care unit (ICU) compared to infusion of placebo in patients with septic shock induced endotheliopathy (SHINE).

Patients that are eligible for this trial will be temporarily incompetent due to acute severe illness relating to septic shock, therefore informed consent will be obtained from a scientific guardian. Next-of kin and subsequently the patient will co-sign as soon as possible hereafter. During the trial, patient will be give continuous infusion of low dose iloprost or placebo for 72 hours as well as additional blood samples will be obtained daily for the first 72 hours. Follow up on organ failure, mortality and quality of life will be performed on dag 28 and 90.

This trial is conducted in accordance with the Helsinki 2 Declaration and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use, Guideline for Good Clinical Practice (ICH-GCP) and in compliance with the protocol. As part of the quality assurance on-site monitoring visit will be performed by the an independent GCP-unit including source data verification. Standard Operation Procedure (SOP) to address protocol specific procedures such as data collection and adverse event reporting are developed.

The number of patients participating is based on a power calculation using the data on mean daily SOFA score from a recent randomized, double blind, placebo controlled clinical trial in patients with septic shock: Levosimendan for the prevention of acute organ dysfunction in sepsis (LeoPARD). If the true effect of the intervention is a reduction in mean daily SOFA score of 20% (relative) and providing the trial with 90% power to detect this difference at a significance level of 0.05 will require a sample size of 380 patients.

A pre-planned, blinded interim analysis will be performed after 200 patients have been included in the trial and followed for 90 days.
