Brain Metastases From Extra-cranial Solid Tumors

This first-in-human study will establish the human safety and radiation dosimetry of the system A amino acid transport substrate, (R)-3-\[F-18\]fluoro-2-methyl-2-(methylamino)propanoic acid (\[F-18\]MeFAMP), for positron emission tomography (PET) imaging of primary and metastatic brain tumors. This study will include 3 cohorts: healthy volunteers for whole body dosimetry estimates (n=6-8, Dosimetry Cohort), patients undergoing evaluation for recurrent high grade glioma after radiation therapy (n=10, high grade glioma (HGG) Cohort), and patients with brain metastases from extra-cranial solid tumors before and after radiation therapy (n=10, Metastasis Cohort). Exploratory assessment of the diagnostic accuracy of MeFAMP for distinguishing recurrent/progressive brain tumors from radiation-related treatment effects will also be performed for subsequent trial design. The study will complete accrual and safety assessment in the Dosimetry Cohort before recruiting for the HGG and Metastasis Cohorts.

CAMPSIS is a preliminary feasibility study of the TheraOne medical device (IIb). TheraOne is an active, non-invasive medical device intended to deliver transcranial FUS in combination with intravenous microbubbles in order to transiently and locally induce the BBB permeability. This study aims to evaluate the safety of cerebral sonication (TheraOne) in the management of patients with recurrent grade 4 glioma (wild-type IDH, technically resectable) or brain metastases originating from an extracranial solid tumor. Patients enrolled in the study will undergo a single sonication session during a protocol visit and will be monitored for up to 30 days after the sonication through the various scheduled protocol visits. Blood samples will be collected at the start of the study, during the sonication, and during the post-sonication follow-up visit for all patients enrolled in the study.

The goal of this study is to evaluate the feasibility and effectiveness of same-day radiation planning and treatment. The study will shorten the time interval between radiation planning (radiation mapping) and radiation treatment. The intent of this shorter time interval is to increase the likelihood that the brain metastases being treated remain fully within the high-dose radiation fields. Participants will be randomized to receive brain-directed stereotactic radiation with a 1mm margin or 0mm margin, have their simulation/radiation planning imaging on the same day that brain-directed stereotactic radiation is delivered, and have repeat simulation/radiation planning scans during the course of treatment if more than 2-3 days have elapsed since the most recent scans.

This is a randomized trial for patients with brain metastases in the primary motor cortex who have not had seizures to receive either the prophylactic anti-seizure medication levetiracetam (also known by its trade name Keppra) or proceed with standard of care management, which does not currently include prophylactic levetiracetam. Patients who enroll to this trial will be randomized to receive prophylactic levetiracetam or not receive prophylactic levetiracetam.
