Abstract
Rotigotine is a new dopamine agonist with transdermal patch formulation for the treatment of Parkinson disease. The aim of this study was to investigate safety and efficacy of rotigotine in patients with early-stage Parkinson disease. In this open-label, dose-escalation, safety and efficacy study, 31 patients in the early stages of idiopathic Parkinson disease received rotigotine to a maximum of 18.0 mg/day. Of the 29 patients who completed the 28-day treatment phase, 24 were maintained at the maximum dose level. The drug was well tolerated, and skin reactions were mild. A statistically significant improvement in UPDRS I, II, and III scores was observed from baseline to end of treatment for the 29 subjects who completed the trial. Mean improvement (+/- standard deviation) was -0.41 +/- 0.78 on UPDRS I (P = 0.0078), -2.76 +/- 3.31 on UPDRS II (P = 0.0001), and -4.62 +/- 5.32 on UPDRS III (P < 0.0001). When results were stratified by maximum dose achieved, significant improvements were seen on all 3 subscores for patients achieving the maximum dose. These data suggest that rotigotine is a safe, well-tolerated, and effective treatment for early-stage Parkinson disease.
