About this study

Official title: Acute Effect of Recombinant Human Brain Natriuretic Peptide in Patients With Pulmonary Hypertension Associated With Acute Exacerbation of Chronic Pulmonary Disease

To evaluate the acute effect of recombinant human brain natriuretic peptide(rhBNP) on pulmonary hypertension of acute exacerbations of chronic pulmonary disease. rhBNP was administered as a continuous infusion for 24 hours , pulmonary artery pressure and other hemodynamic parameters were monitored by Swan- Ganz catheter.

Read the detailed description

Pulmonary hypertension (PH) is a descriptive name for abnormally elevated pressures in the pulmonary vasculature, which seriously affects the quality of life and survival of patients. Currently, no effective drugs treatment was used in patients with pulmonary hypertension due to acute exacerbation of lung disease. Recombinant Human Brain Natriuretic Peptide (rhBNP)was approved in 2001 for use in patients with acute heart failure on the basis of studies showing a reduction in pulmonary-capillary wedge pressure(PCWP) and pulmonary arterial pressure (PAP) and improvement cardiac output (CO) . Thus, the study was designed to administer rhBNP as a continuous infusion for 24 hours on pulmonary hypertension of acute exacerbations of chronic pulmonary disease monitoring by Swan- Ganz catheter. Each patient was studied on two occasions (6 hours apart). One occasion the subject received rhBNP 1.5ug/kg IV bolus followed by an infusion of 0.0075ug/kg/min for 24 hours; other occasion the subject received IV placebo bolus followed by a placebo infusion for 24 hours .these were administered in random order in double blind fashion.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing rhBNP in people with Pulmonary Hypertension, run by LI ZHAO at 1 site in China.

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 5 inclusion and 14 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 1 Oct 2019. 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 China. 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. Some participants in this study may receive a placebo. 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 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?

pulmonary artery systolic pressure (PASP) measured by Swan-Ganz catheter (time frame: baseline , 0.5 hour, 1hour, 2hours, 4hours, 8hours, 12hours, 20hours, 24hours, 27hours and 30hours). The study lists 5 primary outcomes in all. 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 NCT02742909, which also lists 3 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.

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 1 Oct 2019.
