Summary

The purpose of this study is to evaluate the safety, tolerability, immunogenicity, and pharmacodynamic effects of ACI-7104.056 in patients with early stages of Parkinson's disease.

Detailed description

This is a prospective, multicenter, placebo-controlled, double-blind, randomized study with adaptive features, comprising a screening period of up to 8 weeks, a 74-week double-blind treatment period, and a 26-week post-treatment follow-up period. Up to 3 cohorts will include 16 subjects each (12 under the study treatment and 4 under placebo; 3:1 active treatment/placebo ratio). One of the initial potential 3 cohorts (Cohorts 2 and 3 are optional) may be expanded in order to reach an overall total of up to 150 subjects in the study. In case a cohort is expanded, the randomization ratio will be adjusted to achieve an active treatment/placebo ratio of 2:1 in this cohort. The route of administration of the study treatment and placebo will be by intramuscular injections.
