About this study

Official title: Investigation of the Effects of Breakfast or Caffeine Containing Beverages on the Measurement of Plasma Chromogranin A in Patients With Gastro-entero-pancreatic Neuroendocrine Tumours (GEP-NET)

Measurement of plasma chromogranin A remains the most commonly used biomarkers for both screening and monitoring of patients with gastro-entero-pancreatic neuroendocrine tumours (GEP-NET), despite several limitations that include: lack of a reference CgA standard; wide variations depending on the used assay in different laboratories; and varying sensitivity ranges from 60 to 90% with low specificity <50%, depending on the population studied.

Surprisingly, and to the best of our knowledge, only three studies with small numbers of participants have been published that have investigated possible effects of food intake on the measurement of CgA. Most have been performed in healthy controls or patients on treatment with proton pump inhibitors for chronic gastritis (up to n = 11 per group) but only one study has investigated patients with GEP-NET, where n = 6 patients with gastric NET were included.

In this study, the investigators aim to assess the time dependent effects of normally ingested diet (5-item English breakfast; or tea or coffee; or ongoing fasted state) on plasma chromogranin A measurements, using timed measurements over 180 min following an > 10 hours overnight fast, in a randomised double-crossover design. The investigators aimed to include 25 - 35 patients with a histologically confirmed diagnosis of a GEP-NET of varying primary tumour location, tumour stage, grade; and presence or absence of treatment with long acting somatostatin analogues; as well as 10 - 15 healthy controls. In an additional small subgroup of patients who are initiated on treatment with GLP-1 analogues i.e. for type 2 diabetes or obesity, the investigators aim to establish whether injection of GLP-1 analogues has any effects on plasma CgA measurements.

Questions about this trial

What is this clinical trial studying?

A study testing ongoing fasted state, intake of caffeine containing beverages or 5-item English breakfast in people with Neuroendocrine Tumors, run by University Hospitals Coventry and Warwickshire NHS 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 14 inclusion and 16 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 20 Jun 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 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. 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?

changes in plasma CgA measurements related to intake of food or caffeine containing beverages, as compared to ongoing fasted state (time frame: up to 180 min). 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 20 Jun 2024.
