Study Summary

The purpose of this randomized, double-blind, placebo-controlled study is to assess the efficacy of BIA 28-6156 over placebo in delaying clinical meaningful motor progression over 78 weeks in subjects with Parkinson's disease who have a pathogenic variant in the glucocerebrosidase 1 (GBA1) gene (GBA-PD).

Primary Outcome

Time from baseline to clinically meaningful progression on motor aspects of experiences of daily living, as assessed by ≥2-point increase from baseline in Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part II score and no improvement in the Motor Examination, as assessed by ≥0-point increase from baseline in MDS-UPDRS Part III score. MDS-UPDRS is a multimodal scale assessing impairment and disability consisting of 4 parts. Part II assesses motor experiences of
