Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This open-label pilot study will evaluate the safety, tolerability, feasibility, and preliminary efficacy of repeated low-intensity focused ultrasound pulsation (LIFUP) targeting the ventral intermediate nucleus (Vim) of the thalamus in patients with Essential Tremor (ET). Twelve adults with clinically diagnosed ET will undergo six LIFUP treatment sessions over approximately two weeks using the BrainSonix BX Pulsar 1002 system. Tremor severity will be assessed using clinician-rated scales (TETRAS and FTM), patient-reported quality-of-life measures (QUEST), and objective accelerometry before and after treatment sessions, with additional follow-up visits at one and three months post-treatment. MRI scans will be performed at baseline and after the final treatment session to monitor safety. The study aims to characterize whether non-ablative focused ultrasound can safely and transiently modulate tremor-related thalamic circuits and provide preliminary evidence supporting future controlled trials of LIFUP for ET.
