About this study
Official title: A Randomized, Double-Blinded, Placebo-Controlled Study of Two Doses of NATRECOR hBNP (Nesiritide) Administered as a Continuous Infusion in Subjects With Decompensated CHF
The purpose of this study is to assess the safety and efficacy of two doses of intravenous NATRECOR® hBNP (a recombinant form of the natural human peptide normally secreted by the heart) versus placebo in the treatment of patients with symptomatic, decompressed congestive heart failure (CHF).
Read the detailed description
Human studies reported by SJ Holmes et al, 1993, AM Richards et al, 1993 and M. Yoshimara et al, 1991 show that administration of externally produced hBNP produces vasodilation; antagonism of the hormone system that helps regulate long term blood pressure and blood volume in the body; and an increase in urine output containing large amounts of salt. These studies suggest hBNP may be a potent agent for the treatment of acute congestive heart failure (CHF) with a unique combination of desirable effects on the flow of blood throughout the body; the hormones secreted by the nervous system; and support of copious salt outputs by the renal system not provided by currently available therapies. Plasma hBNP levels are elevated in CHF and hBNP may be one of the body's natural compensatory mechanisms to augment cardiac functions in a failing heart. NATRECOR® hBNP is Scios' proprietary form of hBNP and it is identical to the amino acid sequence in the naturally occurring hormone. This is a randomized, double-blinded, placebo-controlled, multicenter study to determine the efficacy of two distinct doses of NATRECOR® hBNP in patients with symptomatic, decompensated congestive heart failure to decrease pulmonary capillary wedge pressure, as measured by a blinded comparison to placebo after 6 hours of treatment. Patients are randomized to receive either a placebo or one of two doses (0.015 or 0.03 µg/kg/min) of NATRECOR® hBNP. The study hypothesis is that NATRECOR ® hBNP is well tolerated and an effective agent for the short-term management of hospitalized patients with symptomatic, decompensated CHF. Patients are randomized to receive either a placebo or one of two doses (0.015 or 0.03 µg/kg/min) of NATRECOR® hBNP. Doses are administered one time only, an intravenous loading bolus, followed by continuous intravenous infusion for 6 hours.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing nesiritide in people with Heart Failure, Congestive and Heart Decompensation, run by Scios, Inc..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hemodynamic effects assessed by an increase in cardiac output without an increase in heart rate, measured at 1.5, 3, 4.5 and 6 hours.. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00288730, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jun 2011.
