Trial summary

The heart requires nutrients and oxygen carried in the blood to generate energy for healthy pump function. Blood is supplied via heart vessels called coronary arteries. When the arteries narrow the investigators call this coronary artery disease. Read more about this study

About this study

Official title: Diastolic RV EvAluation With Millar Catheter to Investigate the Effect of Glucagon-Like Peptide-1 (GLP-1) on Right Ventricular Function During Elective Coronary Angioplasty and Stenting - DREAM GLP-1

The heart requires nutrients and oxygen carried in the blood to generate energy for healthy pump function. Blood is supplied via heart vessels called coronary arteries. When the arteries narrow the investigators call this coronary artery disease. Narrowing and blockage of the coronary arteries can cause chest pain (angina), breathlessness (due to a reduction in pump function) and if prolonged even irreversible muscle damage known as a heart attack. The investigators can treat patients with coronary artery disease with drugs that reduce the workload on the heart or with balloons and hollow metal tubes (stents) to open the narrowed coronary arteries and improve the blood supply. These treatments can relieve angina, improve breathlessness and avert heart muscle damage during a heart attack. A potential new mechanistic effect is emerging by modulating the type of fuel used by the heart to generate energy more efficiently has been tested in the left ventricle. This study is designed to see if mechanistic effect provides the same protection in the right ventricle. It is hoped that this may further improve heart pump function and reduce the size of a heart attack in patients with coronary artery disease.

What is being measured

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

  1. Improvement in RV diastolic dysfunction (Tau, dP/dt min) between control and GLP-1 groups.

    Tau - the time constant of diastolic relaxation is a sensitive measure of ventricular function.

    Control Group - 15 patients are randomised to receive a placebo saline infusion.

    GLP-1 Group - 15 patients are randomised to receive a GLP-1 infusion.

    Balloon Occlusion One - is performed at the start of the procedure and is a measure of baseline ventricular function.

    Balloon Occlusion Two - is performed directly after a 30 minute infusion of either the saline control or GLP-1.

    All measurements are performed while the patient is in the catheter laboratory.

    Measured: Change betweeen Balloon Occlusion One (Baseline) and Balloon Occlusion Two (30 minutes later)

Secondary outcomes (2)
  1. Improvement in RV systolic function (EF, dP/dt max), between control and GLP-1 groups.

    EF - the Ejection Fraction is the percentage of blood ejected by the ventricle and is considered as a sensitive measure of ventricular function.

    Control Group - 15 patients are randomised to receive a placebo saline infusion.

    GLP-1 Group - 15 patients are randomised to receive a GLP-1 infusion.

    Balloon Occlusion One - is performed at the start of the procedure and is a measure of baseline ventricular function.

    Balloon Occlusion Two - is performed directly after a 30 minute infusion of either the saline control or GLP-1.

    All measurements are performed while the patient is in the catheter laboratory.

    Measured: Change betweeen Balloon Occlusion One (Baseline) and Balloon Occlusion Two (30 minutes later)

  2. Collaterals and microcirculatory differences between control and GLP-1 groups

    Control Group - 15 patients are randomised to receive a placebo saline infusion.

    GLP-1 Group - 15 patients are randomised to receive a GLP-1 infusion.

    Balloon Occlusion One - is performed at the start of the procedure and is a measure of baseline ventricular function.

    Balloon Occlusion Two - is performed directly after a 30 minute infusion of either the saline control or GLP-1.

    All measurements are performed while the patient is in the catheter laboratory.

    Measured: Change betweeen Balloon Occlusion One (Baseline) and Balloon Occlusion Two (30 minutes later)

Questions about this trial

What is this clinical trial studying?

A study testing Right Coronary Artery Percutaneous Coronary Intervention and GLP-1 Infusion in people with Right Coronary Artery Percutaneous Coronary Intervention and Right Ventricular Diastolic Dysfunction, run by Papworth Hospital NHS Foundation Trust at 1 site in United Kingdom.

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 4 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 11 Apr 2016. 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 Kingdom. 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.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Stephen P Hoole, BM BCh, MA, DM (01480 364119, stephen.hoole@papworth.nhs.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement in RV diastolic dysfunction (Tau, dP/dt min) between control and GLP-1 groups. (time frame: Change betweeen Balloon Occlusion One (Baseline) and Balloon Occlusion Two (30 minutes later)). 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 NCT02236299, 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 11 Apr 2016.
