A Study of the Safety and Efficacy of Follow-up Serial Infusions of Natrecor(Nesiritide) for the Management of Patients With Heart Failure

2014-08-27 03:54:04 | BioPortfolio

Summary

The purpose of this study is to evaluate the efficacy and safety of Nesiritide administered as serial infusions to heart failure (HF) patients in the outpatient setting.

Description

Heart Failure (HF) is the inability of the heart to pump efficiently and the heart cannot perform the necessary circulation of blood through the body. This can result in symptoms like shortness of breath at rest or with minimal activity. Advanced heart failure is one of the leading causes of hospitalization and deaths in the United States. This is a prospective randomized, double-blind, placebo-controlled parallel group, multicenter study of the effectiveness of Nesiritide administered as serial infusions in the outpatient setting. Patients enrolled in this study will receive nesiritide or placebo for up to 12 weeks. Patients will then be followed for an additional 12 weeks. During the the first 17 weeks of the study patients will have multiple laboratory tests, have their vital signs (blood pressure and heart rate) assessed, and complete quality of life questionnaires. During the last few weeks of the study patients will be contacted to inquire how they are doing. The study hypothesis is that compared to placebo plus standard care, Nesiritide plus standard will reduce time to death or first occurrence of hospitalization due to heart or kidney problems. Safety will be assessed through the collection of adverse events, clinical laboratory tests and vital signs at various time points throughout the study. The patients assigned to the nesiritide group will receive a single 2.0mcg/kg bolus (one time injection) followed by serial IV infusions (4 to 6 hours) at a standard flow rate of 0.010 mcg/kg/min once or twice per week for 12 weeks. The patients assigned to the placebo group will receive matching placebo.

Medical and Biotech [MESH] Definitions

A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)

Agents that have a strengthening effect on the heart or that can increase cardiac output. They may be CARDIAC GLYCOSIDES; SYMPATHOMIMETICS; or other drugs. They are used after MYOCARDIAL INFARCT; CARDIAC SURGICAL PROCEDURES; in SHOCK; or in congestive heart failure (HEART FAILURE).

A semisynthetic digitalis glycoside with the general properties of DIGOXIN but more rapid onset of action. Its cardiotonic action is prolonged by its demethylation to DIGOXIN in the liver. It has been used in the treatment of congestive heart failure (HEART FAILURE).

A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Disease of CARDIAC MUSCLE resulting from chronic excessive alcohol consumption. Myocardial damage can be caused by: (1) a toxic effect of alcohol; (2) malnutrition in alcoholics such as THIAMINE DEFICIENCY; or (3) toxic effect of additives in alcoholic beverages such as COBALT. This disease is usually manifested by DYSPNEA and palpitations with CARDIOMEGALY and congestive heart failure (HEART FAILURE).
