Brief Summary

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

After one year neuroleptic maintenance treatment in patients with first episode schizophrenia, neuroleptic treatment will be continued vs. stepwise discontinued (randomized design) over a period of 1 year. Under both conditions prodrome based early intervention take place.

Detailed Description

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

After one year neuroleptic maintenance treatment in patients with first episode schizophrenia, neuroleptic treatment will be continued vs. stepwise discontinued (randomized design) over a period of 1 year. Under both conditions pharmacologic early intervention strategies in case of early sign of relapse will be applied.
