About this study

Official title: The Use of Nesiritide in the Management of Acute Diastolic Heart Failure

Primary objective is to assess the effect of nesiritide in decreasing left ventricular (LV) filling pressure, defined as pulmonary artery capillary wedge pressure (PCWP) in a group of patients admitted with acute diastolic heart failure.

Secondary objectives include: improvement in symptoms, exercise tolerance, improvement in Doppler diastolic filling parameters in patients with diastolic heart failure.

Read the detailed description

Patients with diastolic heart failure often have high pressure in their heart and lungs and many symptoms such as shortness of breath, low energy, fluid retention, and fatigue. Decreasing the pressure in the heart and lungs may help these patients feel better. The drug nesiritide was designed to help treat heart failure. It has also been shown to help decrease the pressure in the lungs.

Before treatment starts, you will be asked questions about your medical history and about any medications you are currently taking. You will have a complete physical exam. You will have an electrocardiogram (ECG - a test that measures the electrical activity of the heart) and routine blood tests (about 2 teaspoons). You will have an ultrasound on your heart called an echocardiogram to measure your heart function and the pressures in your lungs. Your ability to breathe will be evaluated. With the aid of the research nurse, you will have a 6-minute walk test. You may stop or sit down at any time during the test. This test is being done to evaluate your energy level. You will also be asked to complete a questionnaire about your symptoms. This questionnaire should take no more than 10 minutes to complete.

In order to measure the pressure in your heart and lungs, you will have a procedure called a "right heart catheterization". This is a procedure that may have been done as part of your standard of care even if you were not enrolled in this study. For this procedure, a small tube will be placed in a vein in your neck. A longer tube will be inserted into the first tube and fed through the vein and into your heart. This tube will be used to measure the pressure in your heart and lungs. After the pressures are measured, you will receive treatment with nesiritide during the right heart catheterization procedure.

Nesiritide will be given as a continuous infusion (for 48 hours) by vein. The pressures in your heart and lungs will be measured again at 15, 30, then 60 minutes after you begin to receive nesiritide. The tubes will then be removed from your heart. You will be awake during this procedure and lying flat on your back. An anesthetic will be used to numb the area of your neck where the tube is placed. The entire procedure (including treatment) should take no longer than 1 hour. You will have an ultrasound of your heart performed immediately before and after the right heart catheterization.

Within 15 minutes of the end of the procedure the echocardiogram, the 6-minute walk test, and the questionnaire about your symptoms will be repeated and your breathing will be re-evaluated.

The nesiritide infusion will remain going through a vein in your arm for the next 48 hours. During this infusion you will remain in the hospital on telemetry floor so that researchers can monitor your blood pressure and watch for irregular heartbeat. After you have received this drug for 48 hours, the drug will be stopped. Within 24 hours after stopping treatment, an echocardiogram and a 6-minute walk test will be performed. You will also answer questions about your breathing and your quality of life. These should take no more than 15 minutes of your time to complete.

You will be taken off study if your condition gets worse or intolerable side effects occur.

At 2 and 4 weeks after your hospitalization and the right heart procedure, you will have follow-up visits scheduled. At these visits, you will have a complete physical exam, and possibly have blood work done if required by the doctor as part of your routine care. A blood test to check a BNP (B-type natriuretic peptide) level will also be performed . This is a special blood test to give researchers information about your heart and how much extra fluid you may be carrying with you because of your heart disease. Only 1 teaspoon of blood is needed for this test although up to 3 teaspoons of blood may need to be drawn depending of what blood tests your doctor orders at the follow-up visits.

This is an investigational study. Nesiritide is FDA approved and is commercially available for the treatment of heart failure. However, the use of nesiritide for diastolic heart failure is under research. About 20 patients will take part in this study. All will be enrolled at UTMDACC.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effectiveness of nesiritide in improving symptoms, including pressure in heart and lungs, related to diastolic heart failure (condition where heart muscle is stiff and not able to relax completely, causing the pressures in heart to increase).

    Measured: 2 Years

Who may be eligible to take part?

The sponsor lists 7 inclusion and 9 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 7 Nov 2018. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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. 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?

Effectiveness of nesiritide in improving symptoms, including pressure in heart and lungs, related to diastolic heart failure (condition where heart muscle is stiff and not able to relax completely, causing the pressures in heart to increase). (time frame: 2 Years). 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 NCT00083772, which also lists 5 linked publications.

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.
