Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an exploratory study to preliminary assess safety and efficacy of an adaptive Deep Brain Stimulation (DBS) closed-loop method in patients with PD.

The study has been designed as a double blind randomized crossover trial that uses conventional DBS as a concurrent control in PD patients in need of Implantable Pulse Generator (IPG) replacement.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PD patients in need of IPG replacement will be screened to identify the ones eligible for enrollment.

Randomized patients will undergo 2 days of experimental sessions (i.e. one per each type of stimulation mode, cDBS and aDBS), in a well-controlled environment (i.e. during hospitalization). During each experimental session experienced neurologists will collect information on safety and efficacy endpoints.

adaptive DBS

Group Type EXPERIMENTAL

adaptive Deep Brain Stimulation

Intervention Type DEVICE

The investigational medical device ("AlphaDBSvext") is a portable, external, dual mode stimulator that can deliver adaptive DBS or conventional DBS for the treatment of PD.

In the adaptive mode, the device records Local Field Potential activity from the implanted DBS electrode and simultaneously delivers stimulation through the same electrode based on the recorded signal.

conventional DBS

Group Type ACTIVE_COMPARATOR

conventional Deep Brain Stimulation

Intervention Type DEVICE

The same investigational medical device ("AlphaDBSvext") is used to deliver conventional DBS for the treatment of PD. In the conventional mode it delivers constant stimulation.
