About this study

Glucagon-like peptide-1 receptor (GLP-1R) is a kind of G protein coupled receptor which regulate the insulin secretion and serves as potential target in the diagnosis of functional pancreas neuroendocrine tumor. The aim of this study was the clinical evaluation of a potential GLP-1R targeted tracer 68Ga-NOTA-MAL-Cys39-exendin-4 for the detection of insulinoma.

Read the detailed description

Since GLP-1R is expressed in human β-cells and highly overexpressed in insulinomas,multiple GLP-1R-targeted radiopharmaceuticals were devoted to insulinoma localization imaging.68Ga-NOTA-MAL-Cys39-exendin-4 is an optimal probe targeting GLP-1R. A single dose of 111-185 Mega-Becquerel (MBq) 68Ga-NOTA-MAL-Cys39-exendin-4 will be injected intravenously. Visual and semiquantitative method will be used to assess the PET/CT images.The investigators will determine the use of 68Ga-NOTA-MAL-Cys39-exendin-4 PET/CT in the detection of insulinomas, and to compare its diagnostic value with conventional imaging.

What participants receive

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

  • 68Ga-NOTA-MAL-Cys39-exendin-4Drug

    After 68Ga-NOTA-MAL-Cys39-exendin-4 injection, the patient drank 300-500ml of water and urinated before the PET/CT scans.

What is being measured

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

  1. Standardized uptake value

    Calculation of the standardized uptake value 68Ga-NOTA-MAL-Cys39-exendin-4 in Diagnosis of Insulinoma

    Measured: 1 year

Secondary outcomes (2)
  1. GLP-1 receptor expression by histology compared to tracer uptake

    Pathological detection of GLP-1 receptor expression in patients' lesions and compared to tracer uptake by PET/CT

    Measured: 1 year

  2. Incidence of Adverse Events

    This study will utilize the CTCAE (NCI Common Terminology Criteria for Adverse Events) Version 4.0 for toxicity and Serious Adverse Event reporting

    Measured: Adverse events within 1 week after the injection and scanning of patients will be followed and assessed

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing 68Ga-NOTA-MAL-Cys39-exendin-4 in people with Insulinoma, run by Nanjing First Hospital, Nanjing Medical University at 1 site in China.

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 5 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 4 Dec 2019. 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 China. 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 phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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 Feng Wang, Ph.D (+8602552271491, fengwangcn@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Standardized uptake value (time frame: 1 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 4 Dec 2019.
