Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study placebo-controlled, randomized, double-blind study is to assess the safety and efficacy of SYN120 in patients with Parkinson's disease dementia (PDD) already treated with a stable dose of a cholinesterase inhibitor.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study includes a Screening Period of up to 6 weeks, a 16 week Treatment Period, and a 2 week Safety Follow Up Period.

Final eligibility will be determined at the Baseline Visit. Eligible patients will be randomized to receive placebo or SYN120 100 mg once a day (QD).
