Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

Is [18F]Fluorthanatrace safe for use in humans?

The development of [18F]Fluorthanatrace included first-in-human imaging studies, which are initial tests in people to assess safety. While specific safety data is not detailed, these studies are a standard step in ensuring a treatment is safe for further testing.12345

How is [18F] Fluorthanatrace PET/CT different from other treatments for ovarian cancer?

[18F] Fluorthanatrace PET/CT is unique because it uses a special imaging agent to measure the levels of a protein called PARP-1 in ovarian cancer, helping to predict how well a patient might respond to PARP inhibitors, which are a type of cancer drug. This approach is different from standard imaging techniques, as it provides specific information about the cancer's biology and potential treatment response.14567

What is the purpose of this trial?

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.

Eligibility Criteria

This trial is for patients with solid tumors, such as ovarian, fallopian tube, or primary peritoneal cancer. Participants must have at least one tumor lesion of 1.0 cm visible on standard imaging. Pregnant or breastfeeding women and those unable to tolerate imaging procedures are excluded.

Inclusion Criteria

I have or might have had a solid tumor in the past.
You have at least one abnormal spot that can be seen on a regular scan like CT or MRI and is at least 1.0 cm in size.

Exclusion Criteria

Inability to tolerate imaging procedures in the opinion of an investigator or treating physician.
I am not pregnant or breastfeeding.
Any current medical condition, illness, or disorder as assessed by medical record review and/or self-reported that is considered by a physician investigator to be a condition that could compromise participant safety or successful participation in the study.

Findings from Research

The study evaluated [18F]FluorThanatrace ([18F]FTT) as a biomarker to predict response to PARP inhibitors in homologous recombination deficient high-grade serous ovarian cancer, showing that a decrease in [18F]FTT uptake after treatment correlated with positive responses in patient-derived xenograft models and in 11 subjects.
In patients, a significant reduction in [18F]FTT uptake after about a week of PARP inhibitor treatment was associated with improved tumor response and progression-free survival, indicating that [18F]FTT could be a valuable tool for guiding PARP inhibitor therapies.

In a study of 152 ovarian cancer patients, (18)F-FDG PET/CT demonstrated high diagnostic performance with a sensitivity of 98.3% and specificity of 91.2%, making it a reliable tool for detecting recurrent tumors after therapy.
PET/CT was particularly effective in guiding clinical management decisions, such as diagnosing suspected recurrences and assessing treatment responses, highlighting its importance in the follow-up care of ovarian cancer patients.
Is there an impact of 18F-FDG PET/CT on the surveillance and clinical management of recurrent ovarian cancer? Research based on a large sample in a single PET/CT center.Chen, YM., Chen, T., Zee, CS., et al.[2016]
This pilot study involving 14 patients demonstrated that PSMA 18F-DCFPyl PET/MR imaging can effectively detect ovarian cancer, showing significantly higher tracer uptake in malignant lesions compared to normal and benign ovarian tissues.
The results indicate that PSMA uptake is minimal in benign lesions, suggesting that this imaging technique could help differentiate between malignant and non-malignant ovarian conditions, warranting further research with larger patient groups.
