What this trial studies

The MainRexult study aims to assess the efficacy and tolerability of a combination therapy using Abilify Maintena and Rexulti in patients diagnosed with schizophrenia and related disorders. This observational study focuses on individuals who have been on this combination treatment for up to eight weeks. It seeks to provide insights into the real-life effectiveness of this approach, particularly for patients who have not achieved complete symptom relief with standard treatments. The study is designed to gather empirical evidence to support or refute the benefits of adding brexpiprazole to aripiprazole in managing schizophrenia symptoms.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-65 diagnosed with schizophrenia or related disorders who are currently receiving a combination of Abilify Maintena and brexpiprazole.

Not a fit: Patients under 18 years old or those unable to provide informed consent will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a new treatment strategy for patients with schizophrenia who experience residual symptoms despite existing therapies.

How similar studies have performed: While there have been case reports indicating favorable outcomes with this combination therapy, empirical evidence from randomized controlled trials is lacking, making this approach relatively novel.
