MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the efficacy of tolvaptan or placebo in conjunction with optimal (as determined by the investigator) current therapy on the time to all-cause mortality in subjects hospitalized with worsening CHF.
To compare the efficacy of tolvaptan or placebo in conjunction with optimal (as determined by the investigator) current therapy on the time to first occurrence of CV mortality or hospitalization for heart failure.
Embedded Trials (Trial A and Trial B): To compare the efficacy of tolvaptan or placebo in conjunction with optimal (as determined by the investigator) current therapy on the change from baseline in patient-assessed global clinical status at Inpatient Day 7 or discharge, if earlier. |

E.2.2 | Secondary objectives of the trial |
To compare the efficacy of tolvaptan or placebo in conjunction with optimal (as determined by the investigator) current therapy.
To assess the safety of tolvaptan or placebo in conjunction with optimal (as determined by the investigator) current therapy by comparing:

Subjects who are on cardiac mechanical support. 7. History of bi-ventricular pacer placement within the last 60 days. 8. Co-morbid condition with an expected survival less than six months. 9. Subjects with acute ST segment elevation myocardial infarction at the time of hospitalization. 10. History of sustained ventricular tachycardia or ventricular fibrillation within 30 days, unless in the presence of an automatic implantable cardioverter defibrillator. 11. History of a cerebrovascular accident within the last 30 days. 12. Hemodynamically significant uncorrected primary cardiac valvular disease. 13. Hypertrophic cardiomyopathy (obstructive or non-obstructive). 14. CHF due to uncorrected thyroid disease, active myocarditis or known amyloid cardiomyopathy. 16. History of primary significant liver disease or acute hepatic failure, as defined by the investigator. 17. Chronic uncontrolled diabetes mellitus as determined by the investigator. 18.

History of hypersensitivity and/or idiosyncratic reaction to benzazepine derivatives (such as benazapril). 24. History of drug or medication abuse within the past year, or current alcohol abuse. 25. Inability to take oral medications. 26. Participation in another clinical drug or device trial where the last dose of drug was within the past 30 days or an investigational medical device is currently implanted. 27. Previous participation in this or any other tolvaptan clinical trial. 28. Subjects with refractory, end-stage, heart failure defined as subjects who are appropriate candidates for specialized treatment strategies, such as ventricular assist devices, continuous positive IV inotropic therapy, or hospice care. 29. Subjects currently treated with hemofiltration or dialysis. |
