About this study

The goal of this double-blind randomized, placebo-controlled cross-over trial is to evaluate the effectiveness of GerenylGeranylAcetone (GGA) in patients with Heart Failure with a preserved ejection fraction.

The main questions it aims to answer are:

Read more
  • What is the effect of GGA on diastolic function?
  • What is the effect of GGA on endothelial function?

Main study tasks:

  • Participants will be treated with either GGA or placebo for 13 weeks. After this they will have a break (wash-out) period for 6 weeks and then cross over to the other study arm.
  • Cardiac function will be measured using echocardiogram in all participants
  • Renal measurements and endothelial measurements will be performed on the participants.
  • Participants will perform a 5 minute walking distance test for functional capacity.
  • Participants will fill out questionnaires to score signs \& symptoms.

Researchers will compare the patients to themselves to see if the drug improves diastolic- and endothelial function.

Being tested
Iohexol measurement, Geranylgeranylacetone (GGA), Echocardiography, 6-minute walking distance test, EndoPAT

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Iohexol measurement, Geranylgeranylacetone (GGA) and Echocardiography in people with Heart Failure With Preserved Ejection Fraction, run by Amsterdam UMC, location VUmc at 1 site in Netherlands.

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 6 inclusion and 24 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 Apr 2025. 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 Netherlands. 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 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?

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?

Filling pressures (time frame: after 13 weeks of treatment). 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.

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 Apr 2025.
