Study Details

Study Description

Brief Summary

The purpose of this study is to determine whether the treatment strategy of long-term intermittent every 30 days, continuous intravenous infusion for 24 hours of Levosimendan, associated to optimal contemporary treatment for advanced heart failure reduce the incidence of admission for heart failure worsening at 12 months follow up, compared with the strategy based solely in the optimal contemporary treatment for advanced heart failure.

Condition or Disease	Intervention/Treatment	Phase
Advanced Heart Failure	Drug: Levosimendan Drug: Placebo	Phase 4

Detailed Description

Aims: To evaluate the efficacy and safety of long-term, intermittent intravenous administration for 24 hours of Levosimendan for the treatment of advanced heart failure. Main end-point: incidence of admission due to decompensation, defined as first admission to emergency services or hospitalization more than 12 hours due to heart failure worsening.

Secondary end-points: major cardiac events, serious adverse events, change in NYHA scale at baseline, 30 days, 6 and 12 months; effects on inflammatory and neurohormonal activation in heart failure, identify factors associated with better survival of patients, quality of life, cost-effectiveness of treatment.

Study Design: Prospective, randomized, double-blind placebo controlled trial.

Scope of the study: patients with advanced heart failure.

Study Subjects: Patients over 18 years old with advanced HF of any etiology, with at least one admission for acute decompensation treated or treatable with Levosimendan within 6 months prior to randomization.

Interventions: a 24-hour infusion every 30 days of Levosimendan or placebo in addition to optimal pharmacological treatment for HF during 12 months.

Determinations: clinical monitoring, protocol-specified analytical determinations, echocardiographic assessment, invasive hemodynamic assessment, functional assessment by 6 min walk test in corridor, quality of life assessment at baseline, after 30 days, 6 months and 12 months.

Arms and Interventions

Arm	Intervention/Treatment
Active Comparator: Levosimendan infusion of levosimendan at doses of 0.1 mcg / kg / min for 24 hours.	Drug: Levosimendan Patients included in the intervention group receive optimal drug therapy for heart failure symptoms and also infusion of levosimendan at doses of 0.1 mcg / kg / min for 24 hours every 30 days. Failure to reach an appropriate level of heart failure compensation before the deadline of 30 days for the next study drug administration or placebo, the administration of them will be every 15 days. Thereafter, failure to reach an appropriate level of heart failure compensation for patients or worsen after two consecutive infusions of study drug or placebo every 15 days, proceed to open the code patient randomization and and apply the most appropriate treatment.
Placebo Comparator: Placebo infusion of placebo for 24 hours.	Drug: Levosimendan Patients included in the intervention group receive optimal drug therapy for heart failure symptoms and also infusion of levosimendan at doses of 0.1 mcg / kg / min for 24 hours every 30 days. Failure to reach an appropriate level of heart failure compensation before the deadline of 30 days for the next study drug administration or placebo, the administration of them will be every 15 days. Thereafter, failure to reach an appropriate level of heart failure compensation for patients or worsen after two consecutive infusions of study drug or placebo every 15 days, proceed to open the code patient randomization and and apply the most appropriate treatment. Drug: Placebo Patients included in the placebo group receive optimal drug therapy for heart failure and also infusion of placebo at the same infusion rate as levosimendan doses of 0.1 mcg / kg / min for 24 hours every 30 days. Failure to reach an appropriate level of heart failure compensation before the deadline of 30 days for the next study drug administration or placebo, the administration of them will be every 15 days. Thereafter, failure to reach an appropriate level of heart failure compensation for patients or worsen after two consecutive infusions of study drug or placebo every 15 days, proceed to open the code patient randomization and and apply the most appropriate treatment.

Drug: Placebo

Patients included in the placebo group receive optimal drug therapy for heart failure and also infusion of placebo at the same infusion rate as levosimendan doses of 0.1 mcg / kg / min for 24 hours every 30 days. Failure to reach an appropriate level of heart failure compensation before the deadline of 30 days for the next study drug administration or placebo, the administration of them will be every 15 days.
