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 is to assess the tolerability, safety, and efficacy of brexpiprazole (2.0 mg/day) as adjunctive therapy in adult subjects with a diagnosis of MDD with and without anxious distress

Detailed Description

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

The introduction of atypical antipsychotics has created a renewed interest in adjunctive therapy for MDD, particularly for treatment-resistant MDD. Several atypical antipsychotics have been shown to enhance the response to ADT. This is a phase 3, multicenter, randomized, double-blind, placebo-controlled, fixed-dose trial designed to assess the safety and efficacy of brexpiprazole (2.0 mg/day) as adjunctive therapy to an assigned open-label ADT in depressed subjects with and without anxious distress.
