Trial summary

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, primarily used for treatment of type-2 diabetes mellitus. GLP-1 receptors are present on pancreatic islet β-cells, δ-cells and α-cells. Their stimulation increases insulin and somatostatin secretion, and decreases glucagon secretion.

About this study

Official title: A Pilot Clinical Trial Investigating Underlying Mechanisms of Semaglutide Therapy in Heart Failure Patients

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist, primarily used for treatment of type-2 diabetes mellitus. GLP-1 receptors are present on pancreatic islet β-cells, δ-cells and α-cells. Their stimulation increases insulin and somatostatin secretion, and decreases glucagon secretion. In addition, GLP-1 receptor agonists appear to have multiple extrapancreatic actions, which remain poorly defined. In large clinical trials, semaglutide improved the outcomes in obese patients, patients with heart failure with preserved ejection fraction, and decreased the heart failure hospitalizations in patients with type 2 diabetes. The aim of the present study is to investigate the underlying mechanisms of the beneficial clinical effects of semaglutide in the setting of chronic heart failure.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SemaglutideDrug

    10 overweight patients with heart failure will be enrolled, including 5 patients with heart failure with preserved ejection fraction (HFpEF) and 5 patients with heart failure with reduced ejection fraction (HFrEF). The diagnosis of HFpEF and HFrEF will be based on the most recent European Society of Cardiology guidelines for the diagnosis and treatment of heart failure.

    After their baseline blood sample collections, all participants will receive once-weekly subcutaneous semaglutide (Ozempyc, Novo Nordisk A/S Bagsvaerd, Denmark) at a dose of 0.25 mg for 2 weeks, 0.5 mg for 2 weeks, and then 1.0 mg for a period of 12 weeks. At the end of the 3-month and 4-month period, blood sample collections will be repeated. All blood samples will be sent to Stanford Cardiovascular Institute for further analyses. At baseline, and again at 4 months transthoracic echocardiography, 6-minute walk test, and body composition assessment will be performed.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Semaglutide in people with Heart Failure and Obesity, run by University Medical Centre Ljubljana at 3 sites in 2 countries.

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 10 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 7 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States, Slovenia. 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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 Bojan Vrtovec, MD, PhD (+3861 522 1157, bojan.vrtovec@kclj.si), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Interleukin-6 (IL-6) (time frame: 4 months). The study lists 11 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.

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 7 Aug 2024.
