Abstract
BACKGROUND:Rasagiline is a monoamine oxidase type-B inhibitor in development in Japan for Parkinson's disease (PD). The objective of this Phase 3, randomized, double-blind study was to evaluate the efficacy and safety of rasagiline in Japanese patients with early PD (NCT02337725). METHODS:Patients were 30-79 years old with a diagnosis of PD within 5 years. Following a two-week placebo run-in period, patients were randomized 1:1 to receive rasagiline (1 mg/day) or placebo for up to 26 weeks. The primary endpoint was change from baseline in the MDS-UPDRS Part II + III total score (TS). Secondary endpoints included the MDS-UPDRS Parts II + III, III, II, and I TS and safety. RESULTS: In total, 118 patients were randomized to rasagiline and 126 toplacebo. Patient characteristics at baseline were similar in both groups. The change from baseline in the MDS-UPDRS Part II + III TS was significantly greater in the rasagiline vs. placebo group (rasagiline-placebo: -6.39, 95% CI: -8.530, -4.250; P < 0.0001). The mean changes from baseline in the MDS-UPDRS Part II + III, Part III and Part II TS were lower at treatment visits between weeks 6 and 26 in the rasagiline vs. placebo groups. The overall incidence of treatment-emergent adverse events (TEAEs) was 62.4% and 52.4% in the rasagiline and placebo groups, respectively; most frequent TEAE was nasopharyngitis (15.4% and 15.1%). CONCLUSION: Treatment with oral rasagiline 1 mg/day was effective and well-tolerated in Japanese patients with early PD, with a significantly greater improvement in the MDS-UPDRS Part II + III TS vs. placebo, and a similar safety profile.
