Characterization of 18F-Fluciclovine PET Amino Acid Radiotracer in Resected Brain Metastasis

Study Purpose

This study is for patients who have had surgery to remove brain metastasis and are planned to have stereotactic radiosurgery (SRS) after their brain surgery. It will be optional for patients to have a pre-surgery 18F-Fluciclovine PET/CT scan. The goal of the study is to determine whether a specific imaging agent, known as 18F-Fluciclovine, will help physicians evaluate the extent of surgery and determine if there is any visible tumor above what MRI alone can identify as well as improve the physicians' ability to detect recurring disease. This agent (18F-Fluciclovine) is investigational for the imaging of brain metastases.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

 No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Age ≥ 18 years. 2. Performance status, Eastern Cooperative Oncology Group (ECOG) 0-3. 3. Radiographic diagnosis of brain metastasis. 4. Patient planned for surgical intervention for at least 1 metastasis. 5. Patient planned for postoperative SRS. Male or female patients of reproductive potential need to employ two highly effective and acceptable forms of contraception for at least 4 weeks prior to screening and agreement to use such a method during study participation and for an additional 1 week after post-treatment 18F-Fluciclovine PET/CT. Highly effective and acceptable forms of contraception are:
  • - Male condom plus spermicide.
  • - Cap plus spermicide.
  • - Diaphragm plus spermicide.
  • - Copper T.
  • - Progesterone T.
  • - Levonorgestrel-releasing intrauterine system (e.g., Mirena®) - Implants.
  • - Hormone shot or injection.
  • - Combined pill.
  • - Mini-pill.
  • - Patch.
Postmenopausal people on the study (that will not need contraception) is defined as at least one of the following:
  • - Amenorrhoeic for 1 year or more following cessation of exogenous hormonal treatments.
  • - Luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels in the postmenopausal range for women under 50.
  • - Radiation-induced oophorectomy with last menses > 1 year ago.
  • - Chemotherapy-induced menopause with >1 year interval since last menses.
  • - Surgical sterilization (bilateral oophorectomy or hysterectomy).

Exclusion Criteria:

1. Prior anaphylactic reaction to 18F-Fluciclovine. 2. Evidence of leptomeningeal disease. 3. Prior whole-brain radiation therapy. 4. Contraindication to MRI (e.g., due to safety reasons, such as presence of a pacemaker) 5. Pregnant at the expected time of 18F-fluciclovine administration. 6. Expecting to be breastfeeding at the time of 18F-Fluciclovine and unwilling to stop breast-feeding for 24 hours. Temporary cessation of breastfeeding 24 hours after the time of imaging is allowed.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

 NCT05554302
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions

Arms

Experimental: PET/CT, MRI

All patients will obtain an 18F-Fluciclovine PET/CT scan in addition to the planning MRI at the time of SRS treatment (approximately 2-4 weeks after resection). The value of 18F-Fluciclovine in addition to structural information from the MRI will be analyzed. Patients will continue to undergo 18F-Fluciclovine in addition to MRI during routine follow-up to determine the ability of 18F-Fluciclovine PET/CT to identify areas at risk for marginal failure, monitor resection beds for tumor control, identify patients at risk for disease recurrence, and detect patterns of failure.

Interventions

Drug: - 18F-Fluciclovine

Patients will receive 5-mCi dose (+/- 20%) of 18F-Fluciclovine intravenously as a bolus injection. They will be required to fast for at least four hours prior to 18F-Fluciclovine injection. Patients will be positioned for PET/CT brain imaging and will be injected with 18F-Fluciclovine immediately prior to PET data acquisition. PET data will be collected in list mode up to 25 minutes post-injection. PET images will be reconstructed in two ways: as a standard static image of data acquired between 10 to 20 minutes post-injection, and as a dynamic series of four 5-minute frames between 5 to 25 minutes post-injection to allow for motion assessment and correction and time-dependent observations.
