[18F] F-GLN by PET/CT in Breast Cancer

Status Recruiting

Clinical Trial Summary

Patients with known or suspected primary or metastatic breast cancer with one lesion that is 1.5 cm in diameter or greater may be eligible for this study. Patients may participate in this study if they are at least 18 years of age. Up to 40 evaluable subjects will participate in a single imaging cohort. Patients will be stratified for analysis by breast cancer subtype with prioritization to recruit at least 10 estrogen-receptor-expressing (ER+) and 10 triple-negative breast cancers (TNBC). This is an observational study; [18F]F-GLN PET/CT will not be used to direct treatment decisions. While patients and referring physicians will not be blinded to the [18F]F-GLN PET/CT results, treatment decisions are made by the treating physicians based upon clinical criteria. [18F]F-GLN PET/CT imaging sessions will include an injection of [18F]F-GLN. Metabolism data will be collected. Pilot data will be collected to evaluate image quality and collect preliminary information on the uptake of [18F]F-GLN in breast cancer. Uptake measures will be compared to tumor markers of glutamine metabolism, when tissue is available. The safety of [18F]F-GLN will also be evaluated in all subjects.

Clinical Trial Description

Up to 40 patients will undergo approximately 60 minutes of dynamic PET scanning followed by up to 2 static skull-base to mid-thigh scans post injection of [18F] (2S,4R)4-fluoroglutamine ([18F]F-GLN). A baseline FDG-PET/CT will also be performed, either as a routine clinical staging/re-staging scan or as a research scan. If performed as a research scan, the scan may include an optional dynamic imaging session. Some subjects, who undergo systemic therapy as part of their clinical treatment, may also undergo an optional second [18F]F-GLN PET/CT to collect pilot data on the changes in [18F]F-GLN uptake in response to therapy. Subjects who undergo a second [18F]F-GLN PET/CT may have a second FDG-PET/CT, again either as a standard-of-care restaging study or as an optional research scan. The timing of the optional second PET scans will vary depending on the type of treatment the subject is receiving. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
