About this study
Official title: B-Type Natriuretic Peptide (Nesiritide) and Post Myocardial Infarction Left Ventricular Remodeling: Pilot Study Assessing Safety
This study is being done to determine the effects (good and bad) of intravenous infusion of a human brain natriuretic peptide (BNP), Natrecor (nesiritide), a hormone produced by the heart in persons who have just suffered a heart attack. The human BNP, Natrecor (nesiritide) has been approved by the United States Food and Drug Administration (FDA) to be given intravenously for the management of acute heart failure. It is unknown if human BNP may have good effects on the pumping function of the heart after a heart attack.
Read the detailed description
During the 72 hours of intravenous (IV) nesiritide infusion, if the systolic blood pressure decreases to less than 90 mmHg for 5 minutes, the coronary care unit (CCU) sx will be notified and if the systolic blood pressure has not increased to > or equal to 90 mmHg within 45 minutes, the nesiritide infusion will be stopped. All patients will receive other medical therapy as determined appropriate by the physician except for angiotensin converting enzyme inhibitor (ACEI), which will be started 24 hours after IV nesiritide. Lisinopril will be started 24 hours after the start of IV nesiritide at an initial dose of 2.5 mg and to be titrated up by the participants' physician according to their clinical status. The window for the lisinopril doses would be +/- 1 hour.
Patients with any signs or symptoms of post revascularization ischemia will be discontinued from the study.
Blood for the measurement of renin, angiotensin II (Ang II), aldosterone (Aldo), endothelin (ET)-1, norepinephrine, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), cGMP, C reactive protein, tumor necrosis factor (TNF)-alpha, matrix metalloproteinase (MMP)-2 and tissue inhibitor of metalloproteinase (TIMP)-2 will be drawn before the initiation of IV nesiritide, six hours into the infusion before the initiation of ACEI and just before completion of the 72 hour infusion. The window for the blood draw for the six hour time point would be +/- 1 hour and the 72 hour time point would be +/-1 hour or just prior to discharge but not less than 66 hours.
MUGA will be performed within 24 hours after the initiation of the IV nesiritide to assess systolic and diastolic volumes and LV ejection fraction (EF).
Follow up at 4 weeks:
All patients, whether they complete the entire 72 hours of the nesiritide infusion or not, will return 1 month later for a repeat MUGA and blood draw for the neurohumoral profiling and pregnancy test if required by nuclear cardiology. The visit window for the one month return would be 30 to 40 days.

What is being measured
The primary outcome is the main question the study is designed to answer.
Determine the safety of nesiritide at two different dose levels of 0.003 µg/Kg/min and 0.006 µg/Kg/min focusing on the occurrence of hypotension (yes versus no)
Dosing finding comparing the efficacy of 0.003 µg/Kg/min and 0.006 µg/Kg/min on the suppression of aldosterone at 6 hours after the start of infusion as compared to baseline, as a marker of the neurohumoral activity of BNP
Secondary outcomes (1)
Compare the safety of the two doses on left ventricular (LV) remodeling by determining the LV volume and function by multiple gate acquistion scan (MUGA)

Who may be eligible to take part?
The sponsor lists 1 inclusion and 0 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: stopped early, as of the sponsor's last update on 11 Dec 2009. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 was stopped early (reason given: recruitment of subjects was halted prematurely. recruiting subjects halted prematurely). Results are not available in the source record.
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?
Determine the safety of nesiritide at two different dose levels of 0.003 µg/Kg/min and 0.006 µg/Kg/min focusing on the occurrence of hypotension (yes versus no). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
