TREMOR-DOMINANT
PARKINSON'S DISEASE

In an estimated 26% of Parkinson’s disease (PD) patients², the primary symptom is tremor. These patients initially have tremor and as the disease progresses, they may experience onset of other symptoms. However, tremor remains the symptom with the most severe impact on their daily activities.

MR-guided focused ultrasound (MRgFUS) provides an incisionless treatment option for tremor-dominant Parkinson’s patients who do not respond to medications. Candidates for treatment must be Parkinsonian tremor patients 30 years or older.

During treatment, ultrasound waves heat and ablate the deep brain target with no surgical incisions. Treatment is guided by MR imaging for patient-specific planning, real-time temperature monitoring as well as immediate assessment of treatment outcome.

The result for many patients is immediate improvement of tremor with minimal complications.

“All of a sudden, I mean, it just hits you. The relaxation was so instantaneous. It didn’t come on slowly. It was like. one minute you’re all tense. And the next minute you just relax. It’s the best feeling in the world. Yeah, I mean, feel like you can breathe. Like you’re flying.”

Clinical Study

Overview

Insightec sponsored a pivotal trial of the Exablate Neuro platform to evaluate MRI-guided focused ultrasound thalamotomy to treat patients with medication-refractory tremor-dominant Parkinson’s disease (PD).

Efficacy results

Median tremor scores improved 51.9% versus 12.7% for the treatment and sham groups, respectively, at 3-month follow-up.1 There was a trend of improvement from baseline observed in the Exablate-treated group not seen in the sham group which persisted through 12-month follow-up.

Safety results

Insightec-sponsored clinical studies have shown that the most common adverse events associated with this treatment included numbness/tingling (7%), imbalance (4%), gait disturbance (2%) and unsteadiness (1%).

The number in parentheses is the percentage of subjects who experienced the side effect.

Most of these events were classified as mild or moderate, and 58% resolving on the same day as treatment or within one week of treatment. Two treatment-related severe AEs were reported: one subject experienced ataxia/hemiparesis (weakness on one side of the body) which resolved in 30 days and one subject experienced severe hemiparesis. It should be noted that improvements in training, targeting, MR thermal monitoring, and cavitation detection have advanced since the study was conducted.

Safety Information

Important Safety Information

You should have a detailed conversation with your physician regarding complications, also known as adverse events, that you may experience. Insightec-sponsored clinical studies have shown that the most common adverse events associated with this treatment are headache/head pain (35%), dizziness (30%), numbness/tingling (30%), imbalance (20%), and gait disturbance (10%).

The most common treatment-related complications included numbness/ tingling (7%), imbalance (4%), gait disturbance (2%) and unsteadiness (1%). The number in parenthesis is the percentage of active subjects experiencing these adverse events.
