About this study

Official title: Al18F-NOTA-octreotide PET Imaging of the Somatostatin Receptor in Neuroendocrine Tumors: a First-in-human PET/CT Study

The aim of this study is to evaluate the potential of Al18F-1,4,7-triazacyclononane-1,4,7-triacetate-octreotide (Al18F-NOTA-octreotide) as a positron emission tomography (PET) somatostatin receptor imaging agent in patients with neuroendocrine tumors.

Read the detailed description

In the first part of the study, six healthy volunteers will undergo several sequential whole-body PET/CT scans starting from the moment of tracer injection up to six hours post injection for an initial safety assessment and dosimetry study of Al18F-NOTA-octreotide in humans.

In the second part of the study, six neuroendocrine tumor patients, with at least five positive lesions on routine clinical 68Ga-DOTA-peptide PET, will undergo a dynamic PET scan for the first 45 minutes, followed by three single static whole-body PET/CTs up to three hours post injection for an initial efficacy assessment (evaluation of the lesion detection rate) and pharmacokinetics study of Al18F-NOTA-octreotide in humans. Furthermore a first comparison with 68Ga-DOTA peptide PET will be performed.

What participants receive

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

  • Al18F-NOTA-octreotideDrug

    Also called 18F-AlF-NOTA-octreotide, 18F-IMP-466

    One intravenous injection of 4 MBq/kg

  • PET/CTDevice

    Part 1: Healthy volunteers will undergo consecutive whole-body PET scans, including one low-dose CT, for the first 90 minutes. At 150 ± 15 min and 300 ± 30 min post injection two additional static whole-body PET/CT scans will be acquired.

    Part 2: Neuroendocrine tumor patients will undergo a dynamic PET scan for the first 45 minutes, followed by 3 static whole-body PET/CTs at 60 ± 10 min, 120 ± 30 min and 180 ± 30 min post injection.

  • Venous blood samplesOther

    Blood samples will be obtained for laboratory safety evaluation for initial screening and safety evaluation after injection. Furthermore, venous blood samples will be obtained for metabolite analysis and activity measurements (only for patients) at various time points post injection (5 ± 2 min, 10 ± 5 min, 20 ± 10 min, 40 ± 20 min, 60 ± 30 min, 120 ± 60 min).

Study groups in NCT03883776
Study groupRoleWhat they receive
healthy volunteers and NET patientsExperimentalIn the first part of the study, 6 healthy volunteers will receive a single intravenous single injection of Al18F-NOTA-octreotide, followed by whole-body PET/CT scans at various time points for an initial safety assessment and dosimetry study. In the second part of the study, a single dose of Al18F-NOTA-octreotide will be intravenously injected in 6 patients with neuroendocrine tumors. Patients will first undergo a dynamic PET scan, followed by whole-body PET/CT scans at various time points for a pharmacokinetics study and initial efficacy assessment.

What is being measured

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

  1. Potential of Al18F-NOTA-octreotide as somatostatin receptor PET imaging tracer in patients with neuroendocrine tumors

    The primary endpoint will be met if in 4 out of 6 patients, at least two tumor lesions per patient are visualized in case of 5 to 10 known positive lesions on the 68Ga-DOTA-peptide PET, or at least 25% of the known tumor lesions per patient are visualized in case of more than 10 known positive tumor lesions on the 68Ga-DOTA-peptide PET. The study will be partially positive if in at least one patient at least 80% of the known positive lesions on the 68Ga-DOTA-peptide PET is visualized.

    Measured: 1 year

Secondary outcomes (5)
  1. Dosimetry of Al18F-NOTA-octreotide

    Dosimetry will be assessed by means of the sequential whole-body PET/CT scans performed in healthy volunteers. Absorbed dose per unit of injected activity (mGy/MBq) at the organ and whole-body level will be calculated.

    Measured: 1 year

  2. Normal-organ and tumor uptake of Al18F-NOTA-octreotide as a function of time

    Patients will undergo dynamic PET scanning followed by three static whole-body PET/CT scans at different time points post injection. Uptake as a function of time (pharmacokinetics) will be studied using the software package PMOD (PMOD technologies LLC, Zürich, Switzerland). Volumes of interest (VOIs) will be delineated in relevant normal organs and tumor lesions on all PET images and standardized uptake values (SUV) in all these VOIs will be measured to compute normal-organ and tumor uptake as a function of time.

    Measured: 1 year

  3. Identify the ideal time point for imaging after Al18F-NOTA-octreotide injection

    Tumor-to-background ratios as a function of time will be measured. The time point resulting in optimal tumor-to-background ratios, taking into account a realistic implementation in clinical practice, will be defined as the ideal time point for imaging.

    Measured: 1 year

  4. Safety analysis of Al18F-NOTA-octreotide administration: Common Terminology Criteria for Adverse Events (CTCAE) version 4.03

    The impact of Al18F-NOTA-octreotide administration on clinical symptoms and signs and biochemistry values will be evaluated. Baseline values will be recorded and patients will be assessed clinically and with serial biochemical analysis. Adverse events will be scored according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.

    Measured: 1 year

  5. Preliminary assessment of lesion targeting by Al18F-NOTA-octreotide as compared to 68Ga-DOTATATE

    A lesion-by-lesion analysis (visual and semi-quantitative) will be performed to compare the number of detected lesions using both tracers.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Al18F-NOTA-octreotide, PET/CT and Venous blood samples in people with Neuroendocrine Tumors, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.

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 12 inclusion and 29 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 9 Sep 2020. 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 Belgium. 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?

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.

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?

Potential of Al18F-NOTA-octreotide as somatostatin receptor PET imaging tracer in patients with neuroendocrine tumors (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03883776, which also lists 1 linked publication.

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 9 Sep 2020.
