18F-ASIS PET/CT Imaging of Tissue Factor Expression In Patients With Primary and Metastastic Cancer
- Conditions
- Pancreatic CancerBreast CancerOvarian CancerCervix CancerLung Cancer
- Interventions
- Drug: Injection of 18F-ASISOther: PET/CT scan
- Registration Number
- NCT03790423
- Lead Sponsor
- Rigshospitalet, Denmark
- Brief Summary
The primary objective of the trial is to test the new radio tracer 18F-ASIS for PET imaging of tissue factor (TF) expression. The tracer has the potential of identifying tumors with high levels of TF expression, which is expected to correlate with tumor aggression and prognosis. Furthermore, the tracer can potentially be used as companion imaging diagnostic agent for identifying patients eligible for TF directed therapies.
This is a first-in-man study to test the radio tracer in cancer patients. Safety, biodistribution and dosimetry will be evaluated by repeated PET imaging (1 hour, 2 hours and 4 hours post-injection).

This is a first-in-man study to test the radio tracer in cancer patients. Safety, biodistribution and dosimetry will be evaluated by repeated PET imaging (1 hour, 2 hours and 4 hours post-injection).
The primary end points are safety, biodistribution and dosimetry of 18F-ASIS. In addition, the quantitative uptake of 18F-ASIS will be compared to the expression of TF measured directly in tumor tissue obtained by surgery or biopsies. The study will be monitored and evaluated in accordance with the principles of Good Clinical Practice (GCP).

Group Intervention Description 18F-ASIS PET PET/CT scan One injection of 18F-ASIS (app. 200 MBq) followed by 3 PET/CT scans 1 hour, 2 hours and 4hours post-injection 18F-ASIS PET Injection of 18F-ASIS One injection of 18F-ASIS (app. 200 MBq) followed by 3 PET/CT scans 1 hour, 2 hours and 4hours post-injection
- Primary Outcome Measures
Name Time Method 1.Biodistribution of the radiotracer 18F-ASIS estimated by PET 4 hours The biodistribution of the 18F-ASIS radiotracer estimated from the standardized uptake values (SUV) of the major organs obtained from the patient's repeated PET imaging with the radiotracer 18F-ASIS
2.Dosimetry of the radiotracer 18F-ASIS estimated by PET 4 hours Dosimetry will be calculated with the use of OLINDA/EXM software (mSv) based on repeated PET imaging with the radiotracer 18F-ASIS
3. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] 48 hours The safety of 18F-ASIS PET as measured by the number of participants with adverse events within 48 hours following the 18F-ASIS PET assessed by CTCAE v5.0
- Secondary Outcome Measures
Name Time Method 1.Quantitative uptake of the radiotracer 18F-ASIS in tumor tissue 4 hours The patients will be PET scanned 1 hour, 2 hours and 4 hours post-injection of the radiotracer 18F-ASIS. These timepoints will be used for assessment of tumor uptake by the use of maximum and mean standardized uptake value (SUV).
