Essential TremorParkinson Disease

To determine the efficacy of frameless Virtual Cone Radiosurgical Thalamotomy for medically refractory tremor resulting from either Essential Tremor or Tremor-Dominant Parkinson's Disease with the Fahn-Tolosa-Marin Tremor Rating Scale (FTMTRS) in patients who are not candidates for deep brain stimulation (DBS).

Bilateral Treatment of Medication Refractory Essential Tremor

Essential Tremor

The purpose of this study is to see if the MR-guided focused ultrasound (MRgFUS) thalamotomy procedure can be performed on both sides of the brain safely and effectively to reduce bilateral tremor.

Functional Neuroimaging Feedback for Focused Ultrasound Thalamotomy

Essential Tremor

Focused ultrasound for Essential Tremor is an FDA approved treatment performed by neurosurgeons at the Ohio State Center for Neuromodulation that utilizes ultrasound technology to create a lesion in the thalamus of Essential Tremor patients. In order to improve long term effectiveness and reduce potential for side effects, brain imaging may be used to examine the functional connectivity of certain brain networks during the procedure. In order to investigate functional connectivity changes with these long term goals in mind, in this study neuroimaging will be taken immediately before, immediately after, and 24 hours after the focused ultrasound procedure for 10 Essential Tremor patients. One series of neuroimaging will also be conducted for 20 healthy control subjects to serve as a comparison. This study will not introduce any risks above standard of care, and may lead to improved long term outcomes of patients undergoing the Focused Ultrasound procedure.

A Clinical Trial of 2 Doses of PRAX-944 in Participants With Essential Tremor

Essential Tremor

This multi-center, randomized, double-blinded, placebo-controlled, dose-range-finding clinical trial (with an optional Extension comprised of an Extension Double-blind (DB) Lead in Period followed by an Extension Open-label (OL) Period) that will assess the efficacy, safety, and tolerability of PRAX 944 in participants aged 18 years or older who have a diagnosis of Essential Tremor (ET) and have had symptoms for at least 3 years.

Transcranial Ultrasound Therapy of Essential Tremor

Essential Tremor

Context. Essential tremor (ET) is a common disease, disabling in severe forms and resistant to drug treatment. In patients with severe ET, invasive neurosurgical technique such as deep brain stimulation of the Ventral Intermediate (VIM) nucleus of the thalamus is used. Focused ultrasound therapy, creating a small lesion of VIM represents an effective therapeutic alternative of low morbidity with the advantage of not requiring the opening of the skull and penetration into the brain. This therapy is performed under stereotactic guidance. Validation of the target before lesioning is done by testing the clinical effect by a gradual increase in temperature, resulting in tremor reduction. However, the gradual temperature increase in the targeting phase is suboptimal because it can decrease the efficiency of the lesioning procedure. The aim of this research project is to test an innovation of fundamental physics developed by the Langevin Institute, which would allow the reversible modulation of nerve tissue by ultrasonic waves without heating, to predict the effectiveness of treatment of the chosen target within the VIM before creating an irreversible lesion. Methodology: Fifteen patients with severe and resistant essential tremor will be included in the study. A multimodal MRI will be performed for target calculation using several targeting methods for VIM developed during step 1. For each target, the application of neuro-modulation by ultrasound will allow determine the effect obtained on the tremor (quantified with adequate clinical scales - as Tremor rating scale (CRST), and the recording of electromyographic activity of the upper limbs) and the absence of side effects. A definitive millimetric lesion will be performed at the level of the most relevant target in order to maintain the clinical effect obtained. The procedure will be controlled by thermal MRI sequences. Post-therapy clinical and MRI multimodal follow-up will take place on D1, D7, M1, M2, M3, M6, M12 and M24. Perspectives and Innovation: This project will test clinically the low intensity ultrasound neuromodulation jointly developed by the Langevin Institute and the Brain and Spine Institute ( ICM) in order to refine the targeting procedure of high intensity transcranial focused ultrasound therapy. In perspective, reversible neuromodulation performed in vivo in humans represents a considerable advance in the exploration and future treatment of neurological and psychiatric diseases such as depression. The translational collaboration between the physicists of the Langevin Institute, the ICM and the medical services of the Pitié-Salpêtrière guarantees the feasibility and quality of this first joint therapeutic trial.

A Study to Investigate the Efficacy and Safety of NT 201 (Botulinum Toxin) Compared With Placebo...

Essential Tremor of the Upper Limb

The purpose of this study is to determine whether a single treatment with administration of NT 201 (botulinum toxin) is superior to placebo (no medicine) for one-sided treatment of essential tremor in the arm (Unilateral Period). Participants will be assigned to the treatment groups by chance and neither the participants nor the research staff who interact with them will know the allocation. The following treatment cycle will investigate the safety and tolerability of two-sided treatment with NT 201 (botulinum toxin) (Open Label Bliaterial Period). All participants will receive NT 201 treatment.
