This phase I trial studies how well fluorine F 18 fluorthanatrace positron emission tomography (PET)/computed tomography (CT) works in patients with solid tumors. Fluorine F 18 fluorthanatrace is a radioactive tracer, a type of imaging agent that is labeled with a radioactive tag and injected into the body to help with imaging scans. PET/CT uses a scanner to make detailed, computerized pictures of areas inside the body. PET/CT with Fluorine F 18 fluorthanatrace may allow more tumor cells to be found in patients with ovarian, fallopian tube, or primary peritoneal cancer.



  • Evaluate fluorine F 18 fluorthanatrace ([18F]Fluorthanatrace) positron emission tomography/computed tomography (PET/CT) as an imaging biomarker of poly [ADP-ribose] polymerase (PARP)-1 activity in 3 cohorts of cancer patients: 1) ovarian, fallopian tube, primary peritoneal 2) breast cancer, and 3) non-ovarian, non-breast solid tumor.


  • Evaluate the safety of [18F]Fluorthanatrace.
  • Correlate [18F]Fluorthanatrace uptake measures with BRCA mutation status.
  • Correlate [18F]Fluorthanatrace uptake measures with poly [ADP-ribose] polymerase (PARP-1) activity in tumor tissue samples in patients who undergo biopsies.
  • Evaluate change in [18F]Fluorthanatrace uptake measures after therapy.

Patients receive fluorodeoxyglucose (FDG) intravenously (IV) and undergo FDG PET/CT scan over 20-30 minutes if they have not already had one per standard of care. At least 20-24 hours later, patients receive fluorine F 18 fluorthanatrace IV and undergo fluorine F 18 fluorthanatrace ([18F]FTT) PET/CT over 1 hour.

After completion of study treatment, patients are followed up at 24 hours.
