Official title
Use of Levosimendan as Treatment of Aneurysmal SubArachnoid Hemorrhage
Overview
Sub-arachnoid haemorrhage (SAH) are often due to ruptured intracerebral aneurysms and are associated with an importante morbi-mortality. SAH are often complicated by delayed cerebral ischemia (DCI) potentially due to cerebral vasospasm (CVS). A recent study showed that levosimendan, an inotropic and vasodilatory drug, could reduce the incidence of CVS and potentially improve patient outcome. In this pilot randomized controlled trial, we will evaluate the impact Levosimendan vs Placebo in SAH patient on the occurrence of CVS and DCI. Study population: adult patient admitted to ICU for aneurysmal SAH WFNS grade I-IV and mFisher 3-4. Intervention: Levosimendan (0.1 µg/kg/min) or placebo infusion at Day 1 and 8. Primary outcome: incidence of DCI or CVS at day 14 Duration of the study: 24 months Number of patients: 30 (15 patients per group) Number of center: 1
Detailed description
Background
Aneurysmal subarachnoid hemorrhage (aSAH) is a frequent type of stroke. It is associated with a significant morbidity and mortality and particularly affects young subjects. Complications that can occur after an aSAH include acute cardiac dysfunction and cerebral arterial vasospasm (CVS), which produces delayed cerebral ischemia (DCI). These complications are associated with a worsened outcome for aSAH patients. There is no proven preventive treatment for these complications.
Clinical and experimental data show that Levosimendan could be ideal to prevent these complications. In a recent study (Trinh-Duc et al, Crit Care 2021), treatment with Levosimendan was associated with a reduced incidence of CVS in a SAH patients.
The use of levosimendan, a non-catecholaminergic vasodilator inotrope in a context of already maximal endogenous adrenergic stimulation, thus seems to be suitable and able to improve the prognosis of aSAH patients.
Experimental design
Single-center, phase II, comparative, randomized, superiority, placebo-controlled, double-blind, pilot drug trial using Bayesian inference.
Study drug
Patient treated with levosimendan infusion at 0.1 microgram/kg/min for 24 hours at D1 and D8.
Number of patients
30 patients, i.e. 15 patients per group
Number of centre : 1
Duration of inclusion: 24 months
Total duration of the trial: 27 months
Statistical analysis
Primary endpoint:
The proportion of patients with at least one of the following: death, vasopasm, or DCI within 14 days of inclusion will be compared using Bayesian analysis.
Secondary endpoints:
* Qualitative secondary endpoints will be analyzed by Chi-2 test. An exact probability test will be used if the Chi-2 validity criteria are not met. * Quantitative secondary endpoints will be compared by Student's t test. Qualitative secondary endpoints will be compared by Wilcoxon test * The evolution of mortality will be compared using a log-rank test * The tests will be two-sided at the 5% significance level.
Support
This study is supported by Assistance Publique - Hôpitaux de Paris (AP-HP) and Orion Pharma.
