Overview
Brief Summary
A Multicenter, Double-blind, Randomized, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Tolvaptan in the Treatment of Cardiac-Induced Edema in Patients with Heart Failure
Detailed Description
Interventional, phase III, 2-arm parallel group, placebo-controlled, multicenter, randomized 1:1, double-blind study, comparing Tolvaptan and placebo in hospitalized HF patients with signs or symptoms of congestion at the time of randomization in spite of standard therapy.This study intends to demonstrate that a repeated 4-day treatment with Tolvaptan in addition to standard of care (SOC) is superior to SOC alone for the treatment of clinical relevant cardiac-induced volume retention parameters in patients hospitalized for worsening HF initially treated with conventional therapy including diuretics.

Eligibility Criteria
Inclusion Criteria
- •Patients with history of chronic HF hospitalized primarily for worsening HF with signs or symptoms of volume congestion in spite of standard therapy
- •Patient should have HF symptoms at rest or minimal exertion and signs of congestion (lower limb edema, jugular venous distention, or pulmonary congestion due to extracellular volume expansion) at time of randomization c. Anti-aldosterone drugs: Spironolactone, Triamterene
- •Patients undergoing any of the following diuretic therapies:
- •A loop diuretic at a daily dosage equivalent to 40 mg or more of furosemide
- •Concomitant administration of a loop diuretic and a thiazide diuretic (at any doses)
- •Concomitant administration of a loop diuretic and an anti-aldosterone drug (at any doses)
- •Note: The allowable types and dosages of the concomitantly administered diuretics are specified as follows:
- •Loop diuretics equivalent to 40 mg of furosemide:
- •Bumetanide: 1 mg, Piretanide: 6 mg, Azosemide: 60 mg, Torasemide: 8 mg
- •Thiazide diuretics: Hydrochlorothiazide, Trichloromethiazide, Benzyl hydrochlorothiazide, Chlortalidone, Mefruside
Exclusion Criteria
- •Cardiac surgery within 60 days of enrollment
- •Patients with an assisted cardiac mechanical device
- •Patients receiving CRT (Cardiac Resynchronization Therapy) within 60 days of enrollment.
- •Patients with active or significant complications or symptoms as follow:
- •Suspected decrease in circulatory blood flow
- •Refractory end-stage HF (patients considered to require mechanical circulatory support, continuous intravenous positive inotropic therapy, referral of cardiac transplantation, or hospice care)
- •Cardiac valvular disease with significant heart valve stenosis
- •Sustained ventricular tachycardia or ventricular fibrillation within 30 days prior to screening examination
- •Acute myocardial infarction within 30 days prior to screening examination
- •Cerebrovascular disorders within 6 months prior to screening examination (other than asymptomatic cerebral infarction)
