FDA approves Activa DBS system for Parkinsons of at least 4 years duration- Medtronic

Medtronic has announced FDA approval of Medtronic Deep Brain Stimulation (DBS) Therapy for use in people with Parkinson's disease of at least four years duration and with recent onset of motor complications, or motor complications of longer-standing duration that are not adequately controlled with medication. In 2002, the FDA initially approved Medtronic DBS Therapy for use in patients with advanced Parkinson's disease. Medtronic DBS has demonstrated improvement in motor complications, quality of life, activities of daily living and reduction in medication usage in individuals with Parkinson's disease.

This approval by the FDA was based on data from the EARLYSTIM clinical study, published in the New England Journal of Medicine in 2013, which found that patients treated with Medtronic DBS Therapy and best medical therapy (BMT) reported a mean improvement of 26 percent in their disease-related quality of life at two years, compared to a one percent decline in patients treated with BMT alone. In a study of patients with longer-standing motor complications, DBS patients' quality of life improved 20 percent from baseline to six months compared to no improvement in the patients treated with BMT alone.
