May 19, 2011 updated by: Scios, Inc.

Follow-up Serial Infusions of Natrecor(Nesiritide) in the Management of Patients With Heart Failure-FUSION II

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Had at least two qualifying hospitalizations or hospitalization equivalents in the past year, with the most recent hospitalization or hospitalization equivalent within the past 60 days, but who has been out of the hospital at least 5 days (the day of discharge is day 0)
  • Have documentation indicating that the patient was consistently New York Heart Association (NYHA) Class III or IV during the 60 days before randomization
  • Have a Left Ventricular Ejection Fraction less than 40% (measured within 24 weeks before randomization)
  • Are (1)NYHA Class IV or (2)NYHA Class III with highest calculated CrCl, 60mL/min within the previous 30 days
  • Are receiving optimal treatment with long-term oral medications (e.g., diuretics, angiotensin converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), and beta blockers, unless these are documented to be contraindicated or not tolerated)
  • Agree to come to the clinic up to 2 times per week (according to randomization) for 16 weeks of study drug infusions and to participate in all required follow-up assessments through week 24. In addition, agree to be contacted monthly after week 24 for follow-up, until the entire study has been completed

Exclusion Criteria:

  • Have systolic blood pressure consistently <90mm Hg
  • Are unable or unwilling to discontinue intermittent or continuous infusions of dopamine, dobutamine, milrinone, nitroglycerin, or open-label Natrecor beginning at the time of the screening visit
  • Have required recent outpatient IV vasoactive (milrinone, dobutamine, dopamine, nitroglycerin, or open-label Natrecor) therapy as defined as >2 outpatient (excluding emergency room or inpatient) infusions in the last 30 days without a subsequent hospitalization
  • Had, or during the course of the study are anticipated to have, any organ transplantation (heart, liver, lung, kidney, or bone marrow)
  • Had a biventricular pacemaker placed within the 45 days before randomization or a single or dual chamber pacemaker or an automatic implantable cardiac defibrillator placed within the 15 days before randomization
  • Have cardiogenic shock, volume depletion, or any other clinical condition at the time of randomization that would contraindicate the administration of Natrecor
  • Are currently receiving chronic dialysis or have the expectation that dialysis will be required during the next 12 months.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time to all-cause death or first occurrence of hospitalization for cardiovascular and/or renal causes from the day of randomization through week 12.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Number of cardiovascular and/or renal hospital admissions adjusted for duration of observation period through the end of week 12. Days alive and out of the hospital from the day of randomization through the end of week 12.
