Preoperative Levosimendan in CABG Patients With Poor LV Function (LICORN)

February 24, 2016 updated by: Assistance Publique - Hôpitaux de Paris

Effects of Levosimendan Pretreatment in Patients With Low Ejection Fraction (40 % or Less) Undergoing CABG: a Randomised, Double Blind, Multicenter Trial

The investigators want to test the hypothesis that an infusion of levosimendan started prior to CABG surgery can reduce incidence and severity of low cardiac output syndrome in patients with poor LV function (EF 40% or less).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Background: Patients with an ejection fraction of less than 40% are at high risk of developing postoperative low cardiac output syndrome (LCOS). Despite the use of potent inotropic agents or even ventricular mechanical assist devices, the mortality rate of such patients remains very high (from 17 to 38%). Their hospital stay is also prolonged and the cost of care for this population is increased. Two studies have suggested that post-operative administration of levosimendan could reduce hospital length of stay and long term (Day180) mortality in patients with LCOS. In addition a few studies have also suggested that pre-operative infusion of levosimendan (pre-conditioning) could reduce the use of other inotropes and mechanical assist devices in patients at high risk of developing LCOS. Unfortunately, the data supporting the beneficial effects of levosimendan in high risk cardiac surgery patients is very limited. Main goal: To evaluate the efficacy of a pre-operative infusion of levosimendan in high risk patients (EF less than 40%) undergoing cardiac surgery (CABG or combined surgery: CABG and valve replacement) to improve outcome. Secondary goals: To evaluate: 1) the clinical safety of a pre-operative infusion of levosimendan, 2) the costs of care in the levosimendan and control groups. Experimental setup: Prospective, multicenter, randomized versus placebo, double-blind trial. Treatment modalities: levosimendan will be administered by the intravenous route, according to a continuous infusion of 0.1mcg/kg/min over 24 hours. Levosimendan infusion (0.1mcg/kg/min) will be started immediately after induction of anaesthesia. The delay between infusion start and skin incision can be estimated between 30 to 60 min. The investigators decided to skip the bolus infusion that is frequently associated with systemic hypotension, which may result in serious adverse events and protocol exclusion. Study duration and patient follow-up: Patients will be recruited over 23 months. Individual follow-up will last 6 months. Overall duration of study will be 29 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Confirmed low cardiac output syndrome
Time Frame: within the 28 days after ICU admission
Composite of the three following items:the need for inotropic agents beyond 24 hours following the end of levosimendan/placebo infusion; the need for post-operative mechanical assist devices (intra-aortic balloon pump: IABP, extra-corporeal life support: ECLS) or failure to wean from these techniques if they were inserted pre-operatively; the need for renal replacement therapy during ICU stay
within the 28 days after ICU admission

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

mortality at Day 28 and Day 180
Time Frame: 180 postoperative days
180 postoperative days
