DOTATOC PET/CT for Imaging NET Patients

Study Purpose

Neuroendocrine tumours (NETs) are generally slow growing, but some can be aggressive and resistant to treatment. Compared to healthy cells, the surface of these tumor cells has a greater number of special molecules called somatostatin receptors (SSTR). Somatostatin receptor scintigraphy and conventional imaging are used to detect NETs. This study proposes 68Gallium(68Ga)-DOTATOC positron emission tomography/computed tomography (PET/CT) is superior to current imaging techniques. The goal is to evaluate the safety and sensitivity of 68Ga-DOTATOC PET/CT at detecting NETs and other tumors with over-expression of somatostatin receptors.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Observational
Eligible Ages	18 Years and Over
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT03583528
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	British Columbia Cancer Agency
Principal Investigator The person who is responsible for the scientific and technical direction of the entire clinical study.	Francois Benard, MD

Neuroendocrine Tumors, Insulinoma, Gastrinoma, Glucagonoma, Vipoma, Pheochromocytoma, Paraganglioma, Neuroblastoma, Ganglioneuroma, Medullary Carcinoma, Pituitary Adenoma, Medulloblastoma, Merkel Cell Carcinoma, Small-cell Lung Cancer, Meningioma, Carcinoid

Additional Details

Each subject will have two PET/CT scans, one using 68Ga-DOTATOC and the other using 18-Fluoride-Fluorodeoxyglucose (18F-FDG). The 68Ga-DOTATOC radioactive tracer is manufactured for this study under a Clinical Trial Application filed with Health Canada. 18F-FDG is considered standard care and has been approved by Health Canada. After providing informed written consent subjects will complete a medical history questionnaire. Monitoring of adverse events There will be short-term evaluation of adverse events by comparison of vital signs before and after administration of 68Ga-DOTATOC. Twenty-four hours after 68Ga-DOTATOC administration the study coordinator will call the patient and see if they have experienced any adverse events during that time period and complete the adverse event questionnaire found in section 9.6. Follow-up Assessments. The following information will be collected up to 3 years following the PET/CT scans:

- Initiation of a new treatment.

- Laboratory results and pathology reports.

- Results of imaging studies.

- Final clinical diagnosis by physician and relevant clinical notes.

The study is expected to take approximately 4 years for accrual.

Arms & Interventions

Arms

: PET/CT Diagnostic Imaging

Each subject will have two PET/CT scans, one using 68Ga-DOTATOC and the other using 18F-FDG. The 68Ga-DOTATOC radioactive tracer is manufactured for this study under a Clinical Trial Application filed with Health Canada. 18F-FDG is considered standard care and has been approved by Health Canada.

Interventions

Diagnostic Test: - 68Ga-DOTATOC PET/CT

Blood pressure, heart rate, and oxygen saturation levels will be recorded prior to the injection and at 5 - 15 minutes after injection. Each study subject will have an intravenous catheter inserted. The subject will receive a bolus intravenous dose of the radiotracer from an approved study supplier site. The subject will rest in a comfortable chair for 60 minutes. After this uptake phase, the blood pressure, heart rate, and oxygen saturation levels will be recorded again. The subjects will then be taken to a designated washroom and asked to void prior to being scanned in order to clear excreted radiotracer activity from the urinary tract. Subjects are positioned supine, arms down, and centered on the scanner bed and the PET/CT images will be acquired.

Diagnostic Test: - 18F-FDG PET/CT

18F-FDG PET/CT For 18F-FDG as fasting period of 6 hours is required before the scan. Each study subject will have an intravenous catheter inserted. The subject will receive a bolus intravenous dose of the radiotracer from an approved study supplier site. The subject will rest in a comfortable chair for 60 minutes. The subjects will then be taken to a designated washroom and asked to void prior to being scanned in order to clear excreted radiotracer activity from the urinary tract. Subjects are positioned supine, arms down, and centered on the scanner bed and the PET/CT images will be acquired.
