Hub and Spoke, Comparative Outcomes for Parkinson's Disease Treated With Deep Brain Stimulation (Hub&Spoke)
調査の概要
詳細な説明
The proposed outcomes study is a prospective, randomized, multicenter, single blind, non-inferiority clinical trial comparing the safety and efficacy of deep brain stimulation therapy applied in a community-based model for 62 subjects with Parkinson's disease appropriate for STN DBS therapy.
Eight community-based private neurology practices will be networked to Vanderbilt University Medical Center (VUMC). Neurologists for each practice will attend structured educational programs offered by Medtronic in the identification, selection, and management of Parkinson's disease patients with DBS therapy. Following this educational program, each practice will identify subjects for implantation VUMC. Following screening and baseline visits at VUMC, appropriate patients will be implanted with bilateral subthalamic nucleus deep brain stimulating therapy. The initial post-operative programming will be done at VUMC four weeks after implantation. 8 subjects will then be equally randomized with half being followed for long-term management by the community-based neurologist. The other half will be followed at VUMC.
All subsequent outpatient evaluation management of medications and deep brain stimulation will be managed per standard of care at the location assigned by randomization, community-based private neurology practice or VUMC.
All subjects will be enrolled during the first 24 months of the study. Follow-up evaluations at 12 months will be performed at VUMC. Each patient identified by the community-based neurologist for implantation will be assessed at VUMC. This assessment will include a videotaped off and on UPDRS III rating, neuropsychological testing, and appropriateness as outlined in the patient selection educational program. Patients will be implanted by bilateral subthalamic nucleus deep brain stimulation therapy within 120 days of their initial assessment. The initial post-operative programming will be performed four weeks post-operatively, this is all standard of care.
Subjects will then be randomized to be either managed by their community-based neurologist or at VUMC. Follow-up evaluations at 12 months will include a videotaped on and off UPDRS rating and neuropsychological testing, anti-parkinson medication dosages, and quality of life measures.

説明
Inclusion Criteria:
- Patients must have a clinical diagnosis of probable idiopathic PD. The diagnosis will be based upon the presence of at least three of four clinical features according to diagnostic utility (Resting Tremor, Bradykinesia, Rigidity, Asymmetric Onset) and an absence of clinical features suggestive of an alternative diagnosis.
- Demonstrated response to dopaminergic therapy. In order to exclude patients with a possible alternative diagnosis, all subjects included in the study must have demonstrated a good response to DA drugs, defined as demonstrating at least 30% improvement in parkinsonian motor signs, based upon the UPDRS motor examination subscore, following the administration of their DA drug(s) during the screening neurological examination.
- Advanced Parkinson's disease.
- No contraindications to surgery.
- Age between 50 and 75 years old.
- Available for follow-up for the entire duration of the study.
- Informed Consent: The subject understands the risks, benefits, and alternatives to the study procedures and participation in the study.
- MRI within normal range for age
Exclusion Criteria:
- Evidence of an alternative diagnosis or secondary parkinsonism, as suggested by features unusual early in the clinical course: Prominent postural instability, freezing phenomena, or hallucinations unrelated to medications in the first 3 years after symptom onset; dementia preceding motor symptoms; supranuclear gaze palsy (other than restriction of upward gaze) or slowing of vertical saccades in the first year; severe, symptomatic dysautonomia unrelated to medications; documentation of a condition known to produce parkinsonism and plausibly connected to the subject's symptoms (such as suitably located focal brain lesions or neuroleptic use within the past 6 months)
- Uncontrolled medical condition or clinically significant medical disease that would increase the risk of developing pre- or postoperative complications (e.g., significant cardiac or pulmonary disease, uncontrolled hypertension).
- Evidence of dementia
- Major psychiatric disorder
- Previous brain operation or injury.
- Active participation in another clinical trial for the treatment of PD.
- Patients who have demand cardiac pacemakers or who have medical conditions that require repeat MRI scans.
