Double Blind Placebo Controlled Dose Ranging Study of the Efficacy and Safety of Celivarone at 50, 100 or 300 mg OD With Amiodarone as Calibrator for the Prevention of ICD Interventions or Death
Double Blind Placebo Controlled Dose Ranging Study of the Efficacy and Safety of Celivarone at 50, 100 or 300 mg OD With Amiodarone as Calibrator for the Prevention of ICD Interventions or Death
The Primary objective was to assess the efficacy of Celivarone for the prevention of Implantable Cardioverter Defibrillator (ICD) interventions or death.
Secondary objectives were:
The study included a one week screening period, followed by a treatment period ranging between 6 and 19 months.
The treatment was to be continued until the End of Treatment visit scheduled 10-15 days prior to the common Scheduled Study End Date (SSED). The SSED was defined as about 190 days after the last patient randomization date.
The expected recruitment duration was about 14 months and thus the total duration of the study about 20 months. Visits were planned to be performed at baseline, after 5 days, after 14 days, every month for 6 months and then, every three months after 6 months until the end of the study.
Inclusion criteria :
Implantable Cardioverter Defibrillator (ICD) patients with a Left Ventricular Ejection Fraction (LVEF) of 40% or less AND one of the following criteria:
Exclusion criteria :
Patients of either sex aged below 21 years (or the age of legal consent of the country),
Women of childbearing potential without adequate birth control or pregnant or breastfeeding women
Patients with known ICD lead problem (lead dislodgement)
ICD without the following characteristics :
Recent unstable angina pectoris or myocardial infarction (< 4 weeks),
History of torsades de pointes,
Genetic channelopathies including congenital long QT syndrome,
Wolff-Parkinson-White syndrome,
Patients in unstable hemodynamic condition such as acute pulmonary edema within 12 hours prior to start of study medication; cardiogenic shock; treatment with intravenous pressor agents; patients on respirator; congestive heart failure of stage New York Heart Association (NYHA) IV within the last 4 weeks; uncorrected, hemodynamically significant primary obstructive valvular disease; hemodynamically significant obstructive cardiomyopathy; a cardiac operation or revascularization procedure within 4 weeks preceding randomization,
Incessant sustained VT/VF (VT/VF that recurs promptly despite termination attempts) during the three days preceding randomization.
Patients with inappropriate (not triggered by VT nor VF) shocks during the month preceding randomization.
Clinically relevant haematologic, hepatobiliary (ALT, AST > 3 times the upper limit of normal at randomization), gastro-intestinal, renal (serum creatinine > 221 µmol/l (2.5 mg/dl) at randomization), pulmonary, endocrinologic or psychiatric disease.
Patients treated with oral amiodarone (more than 20 tablets during the 2 months preceding randomization)
