|Condition or disease||Intervention/treatment||Phase|
|Cancer||Drug: [18F]F-AraG||Phase 1|
This is an exploratory Phase 1, prospective study assessing the biodistribution and radiation dosimetry of the Positron Emission Tomography [18F]FAraG (VisAcT) in cancer patients selected for immunotherapy and/or radiation therapy. Each patient may have up to two [ 18F]FAraG PET imaging sessions, a baseline scan and a post start of immunotherapy scan. For each imaging session, patients will receive a single injection of [18F]FAraG and undergo a whole-body PET scans an hour after injection of the tracer. Following each imaging session, the patient will be called within 72 hours to note any side effects.
Optional - Blood samples may be collected at up to 9 time points post-injection to analyze whole-blood/plasma time activity of [18F]FAraG in addition an urine sample may be collected post scan.

- Drug: [18F]F-AraG
Single dose IV injection of [18F]F-AraG for each imaging day.
- Visualize biodistribution of the PET tracer [18F]F-AraG pre-immunotherapy [ Time Frame: Up to 6 weeks before immunotherapy is administered ]Whole-body [18F]F-AraG PET scan will be performed after intravenous injection of the PET tracer.consecutive time points the day of the intravenous injection of the PET tracer.
- Visualize biodistribution of the PET tracer [18F]F-AraG post start of immunotherapy [ Time Frame: Up to 12 weeks after start of immunotherapy ]Whole-body [18F]F-AraG PET scan will be performed after intravenous injection of the PET tracer.
