E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to assess the efficacy of ivabradine in controlling heart rate and improving 28-day survival in patients with septic shock. These objectives will be assessed via a two-stage trial: activity (focused on heart rate control) and efficacy (focused on mortality).
|
|
E.2.2 | Secondary objectives of the trial |
-determine the tolerance of ivabradine; -evaluate the impact of ivabradine-driven heart rate control on systemic hemodynamics, myocardial stress, organ dysfunction, morbidity, and intensive care mortality; -determine the pharmacokinetics of ivabradine.
|
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
It is an ancillary study integrated into the protocol. Objectives : scrutinize the pharmacokinetic profile of ivabradine in critically ill patients.. This ancillary study will be undertaken in centers of Greater Paris (Henri Mondor, Pitié-Salpétrière, Bicêtre, Ambroise Paré, Tenon, HEGP, Lariboisière, Cochin, Bichat, Foch, Marne-la-Vallée, Sud Francilien). |

E.5 End points |
E.5.1 | Primary end point(s) |
There are two primary endpoints: -for activity and treatment selection at interim analysis: the percentage of patients with heart rate within the predefined threshold (80-94 bpm) at hour-48; -for efficacy and the final analysis: 28-day mortality.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
a) Tolerance of ivabradine: percentage of patients with bradycardia, atrial fibrillation, phosphenes or blurred vision up to day-17; b) Percentage of patients with a heart rate within the target range (80-94 bpm) at hour-72; percentage of heart rate measurements (assessed every 3 to 4 hours) within the target range at hour-72; changes in heart rate, mean arterial pressure and cardiac output evaluated by the area under the curve (AUC) versus time; c) Organ failures free days (SOFA<3 for each organ) at day-14 and day-28, number of vasopressor- and mechanical ventilation-free days at day-14 and day-28, lactate clearance at day-2 and day-3; d) Repeated echocardiographies [to assess left ventricle systolic (ejection fraction, s wave at mitral annulus by tissue Doppler, and global longitudinal strain if available), and diastolic (early and late mitral inflow by pulse and tissue Doppler) functions] and biomarker assessment (natriurectic peptide and troponin); e) Pharmacokinetics of ivabradine; f) Mortality at ICU discharge, hospital discharge, and day-90; ICU- and hospital-free days at day-28 and day-90
