NCT04063514

Brief Summary

The limitation of treating intrinsic brain pathologies has been circumvented with neurosurgical techniques; however, less invasive approaches may be desirable particularly for widespread or multifocal disease and when long term and repetitive administration is required. This study seeks to investigate the efficacy of focused ultrasound. Patients with either low grade gliomas or neurodegenerative dementias will be evaluated for study candidacy. There are no immediate benefits for patients who choose to participate; however, the information gained from this study will contribute to the research base and help patients in similar situations in the future.

Conditions

Outcome Measures

Primary Outcomes (2)

  • Adverse Event (AE) & Serious Adverse Event (SAE) Reporting

    Per protocol, any suspected adverse events possibly related to the study protocol (e.g., itching, dizziness, headache, or neurological problems) will be tracked and monitored. In the event of a high-grade or serious adverse event, such event will be reported immediately and the study will be discontinued.

    24 hours

  • functional Magnetic Resonance Imaging (fMRI)

    Some functional neuroimaging scans (e.g., high resolution T1-weighted images; Arterial Spin Labeling \[ASL\]; Dynamic Contrast Enhanced \[DCE\] perfusion sequences; post-contrast T1-weighted images, Susceptibility Weighted Imaging \[SWI\], T2 weighted imaging, and T2 Flair) will be used to evaluate longitudinal changes in perfusion as an efficacy measure. The scans will be acquired within one hour before and after the study procedures of focused transcranial ultrasound and infusion of definity microbubbles. Voxel-based comparisons showing perfusion values relative to the acquired data range will be used for quantification and comparison of baseline and post-procedure scans.

    3 hours

Study Arms (1)

Focused Ultrasound

EXPERIMENTAL

The ultrasound treatment will last either 1 hour or 20 minutes total time for the DWL device or Brainsonix Focused Ultrasound Device, respectively.

Other: Focused Ultrasound

Interventions

With focused ultrasound, there is an expected accentuation of local perfusion and potential temporary opening of the blood brain barrier with the aim is to provide better delivery of therapeutic agents including medication, particulates and cellular elements for treatment of neoplastic, inflammatory and degenerative brain diseases. The present study seeks to investigate differences in perfusion between areas treated and untreated by this modality in order to further explore its use in clinical application for the treatment of brain disease.
