First Patient Treated for Essential Tremor in Phase III Clinical Trial


The first essential tremor patient in the pivotal trial for the ExAblate Neuro Focused Ultrasound System has been treated at Stanford, and the study is starting at the University of Virginia, Swedish Neuroscience Institute in Seattle, and Yonsei University Medical Center in Seoul, Korea.

The trial is a multicenter, double-blinded, randomized study to evaluate the efficacy and safety of treatment using the ExAblate Neuro in medication-refractory essential tremor patients. The study builds upon promising pilot studies funded by the Focused Ultrasound Foundation that demonstrated the preliminary safety and effectiveness of FUS in treating target areas deep inside the brain.These studies were published in the New England Journal of Medicine and The Lancet Neurology.

This important study is being funded through a unique public-philanthropy-industry collaboration between the FUSF, InSightec and The BIRD (US-Israel Binational Industry R&D) Foundation.

“We hope this pivotal trial will demonstrate safety and long-term efficacy, leading to the regulatory approval of focused ultrasound to help improve quality of life for people suffering from essential tremor,” said Foundation chairman Neal F. Kassell. “As we move forward, our goal is to continue to build innovative collaborations like our partnership with BIRD and InSightec to rapidly advance new treatments for patients with unmet medical needs.”
