An observational study in Movement Disorders, Neurology and Parkinsons Disease, sponsored by InSightec. Recruiting at 5 sites in 2 countries. Open to participants aged 30 Years to 99 Years. Per ClinicalTrials.gov, last updated 2026-03-20.
Sponsored by InSightec · Observational
This registry is a prospective, multicenter, international, single arm, observational post-approval registry with follow-up at 3, 6, and 12 months, and annually for 5 years. The proposed registry will enroll 60 subjects and will be conducted at approximately 10 centers worldwide.
This is a post-approval registry which is required by of the approval under PMA P150038/S014 for the Exablate® Model 4000 (Exablate Neuro) Type 1.0 and Type 1.1 for unilateral pallidotomy in the treatment of idiopathic Parkinson's Disease with medication-refractory moderate to severe motor complications. Subjects participating in this registry will have received a unilateral pallidotomy using the commercially available Exablate Neuro.
The following assessments will be collected at Baseline, 3, 6, and 12 months post Exablate procedure and annually thereafter for 5 years:
Adverse Events (AEs) (does not apply to Baseline Visit) Medication usage MDS-UPDRS Unified Dyskinesia Rating Scale EQ-5D-5L WPAI-GH Clinician and Patient Global Impression of Change Patient Satisfaction Questionnaire
4,573 studies on the registry are indexed under Parkinson Disease; 1,086 are open to participants now.
This study's planned enrollment of 60 is below the median of 96 across 1,085 observational studies indexed under Parkinson Disease.

The population enrolled in this registry will be comprised of male and female patients that plan to be treated using the Exablate Neuro system for advanced, idiopathic Parkinson's disease with medication-refractory moderate to severe motor complications. Subjects must meet the specific eligibility criteria in order to enroll in this Registry.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

The population enrolled in this registry will be comprised of male and female patients that plan to be treated using the Exablate Neuro system for advanced, idiopathic Parkinson's disease with medication-refractory moderate to severe motor complications. No intervention is performed under this registry protocol.
Device: Exablate Pallidotomy, Unilateral
Unilateral pallidotomy using focused ultrasound for the treatment of Parkinson's Disease with medication-refractory moderate to severe motor complications.
Responder Analysis
Primary Effectiveness will be evaluated through a Responder analysis. Responder is defined as the patient reaching a minimally clinically significant difference on: 1) UDysRS Objective Assessment ON Meds, without clinically significant worsening of MDS-UPDRS Part III OFF Meds aggregated extremity score for treated side Or 2) MDS-UPDRS Part III OFF Meds Motor Exam on the treated side, without clinically significant worsening of UDysRS Objective Assessment ON meds
Time frame: 5 years
Safety Analysis
Safety will be evaluated through descriptive analysis of the incidence and severity of adverse events. Adverse events will be recorded and categorized according to severity, expectedness, and relationship to Exablate Neuro system pallidotomy procedure and/or disease progression.
Time frame: 5 years
Started Jan 2023 (actual). Primary completion is estimated for Jul 2029, 78 months after the start.
Of 60 industry-sponsored observational studies under Parkinson Disease, half reached primary completion within 37 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 64. This study's planned 78 months is above that.
Counting every sponsor, half of 438 studies reached it within 47 months; a quarter within 22 and three quarters within 114.
