24-months Study to Evaluate Safety and Efficacy of Peroneal Transcutaneous NeuroModulation in Subjects With Parkinson's Disease and Essential Tremor

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.
