Overview
This is a pilot randomized, sham-controlled, double-blind, multi-center study evaluating the safety and preliminary effectiveness of the Gen0Bh Transcranial Focused Ultrasound System for the treatment of motor symptoms in individuals with idiopathic Parkinson's disease.
Detailed description
Participants will be randomized in a 1:1 allocation to receive either active or sham stimulation. Both participants and outcome assessors will remain blinded to treatment assignment. The study consists of 20 treatment sessions administered over approximately 4-6 weeks, followed by longitudinal follow-up through 3 months.
Interventions
- Device Gen0Bh Transcranial Focused Ultrasound System (Active)
The investigational Gen0Bh system delivers noninvasive, transcranial focused ultrasound to modulate neural activity in the bilateral globus pallidus. Stimulation parameters, including frequency, intensity, and duty cycle, are pre-specified and controlled by the device software. Treatments are administered by trained study personnel in a clinical setting over 20 sessions across approximately 4 to 6 weeks. - Device Gen0Bh Transcranial Focused Ultrasound System (Sham)
The sham configuration uses the same device platform and mimics all procedural aspects of active treatment, including acoustic coupling, device setup, and session duration, without delivering therapeutic ultrasound energy to the target region. This approach is designed to maintain participant and assessor blinding.
Primary outcome measures
- Change in MDS-UPDRS Part III Total Score (OFF Medication State) [Time frame: Baseline up to 6 weeks]
- Incidence of Serious Adverse Device Events (SADEs) [Time frame: Baseline up to 6 weeks]
Secondary outcome measures (3)
- Motor Function Assessments [Time frame: Baseline up to 6 weeks]
- Patient- and Clinician-Reported Outcomes [Time frame: Baseline through Month 3]
- Psychiatric and Non-Motor Outcomes [Time frame: Baseline through Month 3]
