This is an open label extension of 306 subjects from a previously reported delayed-start phase III clinical trial of rasagiline in early Parkinson's disease. Clinical benefit observed at one year in the early vs. delayed-start arm was maintained over an average 3.6 ± 2.1 years observation, raising the question of whether earlier intervention with rasagiline results in better outcomes.
