Study Summary

This trial will investigate a PET/CT imaging scan to assess PARP-1 expression in pheochromocytoma/paraganglioma patients before surgery/systemic therapy. It won't influence treatment decisions.

Who is the study for?
This trial is for adults over 18 with pheochromocytoma or paraganglioma, confirmed by tests and imaging like CT, MRI, or PET/CT. They must understand the study's research nature and agree to participate. Pregnant or breastfeeding women can't join, nor can those who can't handle imaging procedures or have conditions that may risk their safety in the trial.Check my eligibility
What is being tested?
[18F]FluorThanatrace ([18F]FTT) PET/CT scans are being tested to see how well they show PARP-1 expression in tumors of patients with pheochromocytoma or paraganglioma before surgery or systemic therapy. This observational study won't influence treatment decisions directly.See study design
What are the potential side effects?
Since this is an observational study focusing on imaging techniques rather than drug effects, specific side effects related to [18F]FTT are not detailed here but may include typical risks associated with PET/CT scans such as exposure to radiation.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Cohort BExperimental Treatment1 Intervention
After undergoing screening assessments and verifying eligibility for study participation subjects will be scheduled to undergo a baseline experimental [18F]FTT PET/CT scan prior to systemic therapy with radionuclide or chemotherapy. Up to 10 patients undergoing systemic therapy may undergo a second (optional) scan that will be performed approximately 1-21 days after therapy has started. The second scan is obtained to evaluate whether the initiation of systemic therapy alters [18F]FTT uptake. As this is a pilot study, only a limited number of patients are sought for the second scan.
Group II: Cohort AExperimental Treatment1 Intervention
After undergoing screening assessments and verifying eligibility for study participation subjects will be scheduled to undergo a baseline experimental [18F]FTT PET/CT scan prior to surgery. Patients in Cohort A will undergo surgery with or without additional therapy.
