Trial summary

The investigators hypothesize that the 64Cu-DOTATATE will show uptake in the infected vegetations on the prosthetic heart valves and increase the accuracy of the right diagnosis - thus increasing the sensitivity and specificity compared to 18F-FDG PET/CT Read more about this study

About this study

Official title: 64Cu-DOTATATE PET-CT-skanning to Diagnose Macrophage Infiltration in the Heart Valves of Patients with Infective Endocarditis.

The investigators hypothesize that the 64Cu-DOTATATE will show uptake in the infected vegetations on the prosthetic heart valves and increase the accuracy of the right diagnosis - thus increasing the sensitivity and specificity compared to 18F-FDG PET/CT

Read the detailed description

Infective endocarditis (IE) is an infection of the heart lining, primarily mediated by an endothelial injury causing activation of inflammatory cytokines and cells thus forming a thrombus creating a basis for bacteria adherence. The incidence rate is estimated to 2-10 cases per 100.000 people. In hospital mortality rates have been reported to 14-30%. Hence,it is therefore also worrisome that the incidence of IE has significantly increased in the adult population the last decades. Several reasons for this incline in incidence have been suggested: an increasing elderly population, an increase in the prevalence of prosthetic heart valves and cardiac electronic devices and better diagnostics technique.

Prosthetic valve endocarditis (PVE) is uncommon but severe complication to surgical and transcatheter valve replacement. Early studies have estimated PVE to account for up to 5% of all IE cases, however in recent studies PVE represents an increased proportion of overall infective endocarditis cases -estimated for almost 20%. Staphylococcus aureus is the most common cause of PVE. The mortality rate of PVE patients is significantly higher than native valve endocarditis (NVE) - in hospital mortality is estimated from 22% to 42% for PVE, and one year mortality for PVE is estimated to 21%-80%. The PVE diagnosis is often hard to verify as the symptoms of IE vary broadly.18Fflurodeoxyglukocose positron emission tomography/computed tomography (18F-FDGPET/ CT) is recommended as diagnostic imaging technique, however the sensitivity is 83.5% and specificity is 70.8%. The aim of this trial is to investigate whether 64Cu-DOTATATE will show uptake in the infected vegetations on the prosthetic heart valves and increase the accuracy of the right diagnosis.

Questions about this trial

What is this clinical trial studying?

A study testing 64Cu-DOTATATE and 18F-FDG in people with Endocarditis and Endocarditis;Chronic, run by Emil Loldrup Fosbol at 1 site in Denmark.

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 9 inclusion and 7 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 27 Dec 2024. 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 Denmark. 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.

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?

The number(percentege) of agreement between the two scan modalities in overall population (time frame: 2 year). 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 27 Dec 2024.
