Asleep MRI-guided Versus Awake Microelectrode Recording Guided Deep Brain

Status Not yet recruiting

Clinical Trial Summary

Rationale: Bilateral deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a well-accepted treatment for Parkinson's disease (PD). Traditionally, the procedure is performed awake and under local anaesthesia to facilitate intraoperative monitoring via microelectrode recording and test stimulation for exact electrode positioning. Advances in MR imaging allow for clear visualization of the STN and therefore direct targeting. Retrospective series suggest that MRI-guided and image (CT or MRI)-verified STN-DBS under general anaesthesia yields a similar motor outcome and quality of life (QoL) as awake and microelectrode recording-guided surgery with intra-operative clinical testing. MRI-guided and image (CT or MRI)- verified approach potentially has advantages in terms of patient experience and cost-effectiveness. The study proposed here is the first in the world to directly compare both methods. Objective: To compare bilateral MRI-guided and CT-verified STN-DBS under general anaesthesia to awake microelectrode-guided bilateral STN-DBS with intra-operative clinical testing in terms of motor improvement. Study design: A multicentre comparative effectiveness trial with a non-inferiority design. Study population: 158 PD people eligible for bilateral STN-DBS (79 in each arm). Intervention: This study compares two modalities of standard treatment. One arm receives awake microelectrode recording guided bilateral STN-DBS under local anaesthesia with intraoperative clinical testing. The other arm receives MRI-guided and CT-verified bilateral STN-DBS under general anaesthesia. Main study parameters/endpoints: The primary outcome is the change from baseline to one year in Unified Parkinson's Disease Rating Scale part III (UPDRS III) scores (OFF Medication) versus the postoperative scores (OFF medication and ON stimulation). Secondary objectives include patient experience, quality of life, adverse effects and complications, neuropsychological examination, non-motor symptoms (including psychiatric evaluation), reduction in anti-parkinsonian medication, activities of daily living (ADL) functioning and cost- effectiveness.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
