Potential utility of amantadine DR/ER in persons with Parkinson's disease meeting 5-2-1 criteria for device aided therapy.

ABSTRACT:

Background

The 5-2-1 criteria (≥5 levodopa doses/day, ≥2 h OFF/day, and ≥ 1-hour dyskinesia/day) propose to identify people with Parkinson's disease (PD) who are poorly controlled on oral therapies and who may therefore benefit from device-aided therapies. Amantadine-DR/ER is the only medication FDA-approved for both dyskinesia and OFF episodes in levodopa-treated patients. In this post-hoc analysis of phase 3 clinical trials, we evaluated the efficacy and safety of amantadine-DR/ER in patients meeting 5-2-1 criteria.

Methods

Week-12 treatment differences (Amantadine-DR/ER - placebo) in the Unified Dyskinesia Rating Scale (UDysRS) and PD motor states (patient diaries) were evaluated in pooled, phase-3, double-blind trial participants meeting 5-2-1 criteria at baseline
