Brief Summary

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

The main purpose of this study is to evaluate the cognitive changes after administration of tideglusib versus placebo at two oral doses and two treatment regimes for 26 weeks in patients with mild to moderate Alzheimer's disease.

After the 26 week core treatment period, the patients may continue in the study under blinded conditions for an optional extension period up to a maximum of 39 additional weeks (total study duration up to 65 weeks), until the last patient in the study has completed the 26 week of treatment.

Detailed Description

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

This double-blind, placebo-controlled, randomized, parallel group study will be conducted at multiple centers in the European Union. Patients with mild to moderate Alzheimer's disease will undergo a screening period, and then they will be randomized to one of these four groups: tideglusib 1000 mg once daily (Q.D.), tideglusib 1000 mg every other day (Q.O.D.), tideglusib 500 mg Q.D., or matching placebo, for a 26-week, double-blind, placebo-controlled treatment period.
