New imaging test may help doctors track brain tumor treatment
NCT ID NCT06048094
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a special PET scan (using 18F-Fluciclovine) can help doctors see if brain tumors are responding to radiation treatment. About 46 adults with brain metastases will get the scan before and after stereotactic radiosurgery. The goal is to find a better way to measure treatment success without relying only on standard MRI.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Diagnosis of cancer with radiographic finding of brain metastasis * Any number of brain metastasis, with all lesions ≤ 2 cm in maximum dimension * Planned treatment with SRS as per the treating physician team * Eastern Cooperative Oncology Group (ECOG) performance status 0-2 * Individuals of reproductive potential need to employ two highly effective and acceptable forms of contraception for at least 4 weeks prior to screening and agree to use such a method during study participation up to an additional 1 week following the last 18F-fluciclovine PET Exclusion Criteria: * Prior anaphylactic reaction to 18F-fluciclovine * Radiographic evidence of leptomeningeal disease * Prior whole-brain radiation therapy * Inability to undergo MRI (e.g., due to safety reasons, such as presence of a pacemaker) * Pregnant or positive serum pregnancy test within 14 days of registration * Individuals expecting to be breastfeeding at the time of 18F-fluciclovine and unwilling to stop breast-feeding for 24 hours. Temporary cessation of breastfeeding for 24 hours after the time of imaging is allowed. * Major medical illness or psychiatric/cognitive impairments, which in the investigator's opinion, will prevent completion of protocol and/or preclude informed consent\* * A legally authorized representative (LAR) may consent on a potential participant's behalf in the case of cognitive impairment, if in the investigator's opinion, that impairment would not prevent completion of the protocol.
