VANTAGE Trial: A Prospective, Multi-center Trial Evaluating Deep Brain Stimulation with a New Multiple-Source, Constant-Current Rechargeable System in Parkinson’s Disease (P1.173)
2015
OBJECTIVE:
The VANTAGE study assessed improvement in motor function and overall quality of life in patients with moderate-to-severe Parkinson’s disease (PD) following bilateral subthalamic nucleus deep brain stimulation (DBS) using an implantable, rechargeable, multiple-source, 16-contact, constant-current Vercise DBS system.
BACKGROUND:
Several randomized controlled trials (Deuschl et al. 2006, Weaver e t al. 2009, Okun et al . 2012) have demonstrated that DBS is an effective treatment for patients with Parkinson’s disease. Motor improvement following DBS is sustained up to 10 years (Castrioto et al. 2011).
DESIGN/METHODS:
VANTAGE is a, prospective, multi-center, non-randomized, open-label interventional trial, sponsored by Boston Scientific Corporation. 40 subjects with idiopathic Parkinson’s disease (PD) were implanted bilaterally in the subthalamic nucleus (STN). Subjects were followed at 3, 6 and 12 months post lead placement. Motor improvement was evaluated using UPDRS III scores in stim ON/meds OFF as compared with baseline. Other assessments including quality of life such as PDQ-39, SF-36, Schwab and England were administered. Patient motor diaries were collected over 3 days. Adverse events were recorded.
RESULTS:
A highly significant improvement of 62[percnt] in UPDRS III scores at 12 months post implant in stim on/meds off condition was reported. A 35[percnt] improvement in mean PDQ-39 summary index was reported at 12 months post implant driven by improved Activities of Daily Living, Mobility, and Bodily Discomfort.
CONCLUSIONS:
Highly significant motor improvement, as evaluated using UPDRS III, was demonstrated at 6 months that was further sustained up to 12 months post lead placement. Subjects overall quality of life also improved significantly. The VANTAGE trial is the first reported trial of a multiple-source, constant-current rechargeable system in PD up to 12 months.
