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.

- Subject is currently a user (including ''recreational use'') of any illicit drugs, including cannabis, or has a history of drug or alcohol abuse

- Subject suffers from claustrophobia or cannot tolerate confinement during PET/CT scanning procedures; subject cannot lie still for 60 minutes inside the scanner
- Subject is unwilling to avoid unusual, unaccustomed, or strenuous physical activity (i.e. weight lifting, running, bicycling) from the time of the selection visit until the telephone follow-up interview.
- Subject does not understand the study procedure
- Subject is unwilling or unable to perform all of the study procedures, or is considered unsuitable in any way by the principal investigator
- Subject is potentially pregnant (urinary hCG test will be performed in women where pregnancy is not excluded), wishes to become pregnant up to 3 months after administration of Al18F-NOTA-octreotide or is breast-feeding

Intervention / Treatment |
---|---|
EXPERIMENTAL: healthy volunteers and NET patients
In 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. |
One intravenous injection of 4 MBq/kg
Other Names:
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.
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).

Potential of Al18F-NOTA-octreotide as somatostatin receptor PET imaging tracer in patients with neuroendocrine tumors
Time Frame: 1 year

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.

Time Frame |
---|---|---|
Dosimetry of Al18F-NOTA-octreotide
Time Frame: 1 year
|
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.

Normal-organ and tumor uptake of Al18F-NOTA-octreotide as a function of time
Time Frame: 1 year
|
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.

Time Frame: 1 year
|
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.
