Brief Summary

This study investigates the long-term safety and tolerability of home peroneal eTNM® therapy using the URIS I™ device in subjects with Parkinson's disease (PD) or Essential Tremor (ET). Previously, a 6-week open-label pilot study with 24 PD or ET patients demonstrated that home-based peroneal eTNM® is safe, well-tolerated, and has a high adherence rate of over 90%. No treatment-related adverse events were observed. Although the pilot study was not designed to prove efficacy, it suggested positive effects on tremor, with improvements sustained for weeks after treatment. This extension study aims to further evaluate the long-term safety, tolerability, and efficacy of peroneal eTNM® in PD and ET patients.

Detailed Description

This is a study to investigate the long-term safety and tolerability of home peroneal eTNM® delivered by URIS I™ in subjects with PD or ET. The safety, tolerability and efficacy of the home-based peroneal eTNM® using URIS ITM neurostimulator in the treatment of symptoms related to movement disorders in subjects with PD and ET has been recently investigated in the study (NTC06036368). This 6-weeks, open-label, single-site pilot study enrolled 24 patients with either PD or ET and was completed in April 2024. This pilot study showed that home-based peroneal eTNM® was safe and well tolerated by patients. No adverse events related to treatment were observed during the study period. These data confirm the excellent safety profile of the peroneal eTNM® that has been observed in previous studies in the overactive bladder population. In addition, all patients were able to stimulate themselves at home without assistance. Adherence to the treatment was very high, reaching well over 90 %. Although this pilot study was not designed to demonstrate the efficacy of peroneal eTNM®, due to its pilot nature and the small sample size, the observed results suggest noteworthy positive effects on rest, postural and kinetic tremor as measured visually, by accelerometers and by validated MDS-UPDRS and TETRAS scales. Importantly, patients reported sustained improvement in tremor throughout the treatment and continuously for several weeks after conclusion of the 6 weeks stimulation period. Data obtained at EoS visit (6 weeks after the last stimulation) lend support for a long-lasting persistence of the effect. Based on these data, the present extension study is designed to evaluate the long-term safety, tolerability and efficacy of peroneal eTNM® in patients with PD and ET. The study will use the medical device URIS I™, which has been assessed for conformity and issued a declaration of conformity. This agent will be used for a different indication, or on a different group of patients, however, without any change in the procedure of use. The clinical trial will be conducted in accordance with clinical trial plan TS005.

• Stable dose of any chronic medications, if applicable, for 30 days prior to study entry
• Willing to comply with study protocol requirements.
• Subject agrees not to participate in another study from 30 days prior the baseline visit until the final study visit.
• For subjects with PD:

• Bradykinesia in "on" period based on clinical assessment
• Rigidity in "on" period based on clinical assessment
• Hand/arm exhibiting tremor (resting and/or intentional and/or postural) ≥ grade 1 as assessed by the MDS-UPDRS tremor score in "on" period
• For subjects with ET:

• Visible hand/arm and/or foot/leg tremor (resting and/or intentional and/or postural) ≥ grade 1 as assessed by the TETRAS

Exclusion Criteria

• Implanted electrical medical device, such as a pacemaker, defibrillator, or deep brain stimulator
• Suspected or diagnosed epilepsy or other seizure disorder
• Presence of clinical signs or diagnosis of dementia
• Swollen, infected, inflamed areas, or skin eruptions, open wounds, or cancerous lesions of skin at stimulation site
• Presence of clinical signs of peripheral neuropathy on lower limbs
• Presence of chorea and/or dyskinesia
