Study Details

Study Description

Brief Summary

Not only being the mainstay of treatment for schizophrenia spectrum psychotic disorders, antipsychotics, especially the second-generation antipsychotics (SGAs) have also been recommended as augmenting agents for treating depression. Dopaminergic agents, including both dopamine D2/D3 antagonists and dopamine partial D2 agonists, have been effective for treating psychosis and schizophrenia. Amongst all SGAs, those with partial D2 agonistic property are generally acknowledged to have better side-effect profiles with lower incidence of extrapyramidal side-effects, prolactin increase, weight gain, QTc prolongation, and metabolic syndrome, as well as more efficacious in alleviating depressive symptoms. Up-to-date, three SGAs, namely aripiprazole, brexpiprazole and cariprazine, are known to possess such partial D2 agonism. ReSD-HK study is part of the ReSD Asian Study aiming to carefully evaluate a cohort of patients prescribed with brexpiprazole on its efficacy and tolerability as treatment for schizophrenia and/or depression in a real-life clinical setting.

Condition or Disease Intervention/Treatment Phase

Detailed Description

This is a 6-month, non-interventional, prospective naturalist study that adult patients (18-65 years old) receiving brexpiprazole for treatment of psychosis and/or as adjunctive treatment for major depressive disorder are eligible to participate. Minimal exclusion criteria are employed to fit the usual real-life setting.

Outcome Measures

Primary Outcome Measures

  1. Change in Brief Psychiatric Rating Scale-24 in 6 months [6 months]

    Efficacy measures the change from baseline, to that at 3rd and 6th months

  2. Change in Clinical Global Impression in 6 months [6 months]

    Efficacy measures the change from baseline, to that at 3rd and 6th months

  3. Change in Beck Anxiety Inventory in 6 months [6 months]

    Efficacy measures the change from baseline, to that at 3rd and 6th months

  4. Change in Beck Depression Inventory in 6 months [6 months]

    Efficacy measures the change from baseline, to that at 3rd and 6th months

  5. Change in Digital Symbol Substitution Test in 6 months [6 months]

    Efficacy measures the change from baseline, to that at 3rd and 6th months

  6. Change in World Health Organization Disability Assessment Schedule 2.0 in 6 months [6 months]

    Efficacy measures the change from baseline, to that at 3rd and 6th months

Secondary Outcome Measures

  1. Glasgow Antipsychotic Side-effects Scale in 6 months [6 months]

    Tolerability measures at baseline, at 3rd and 6th months. Higher score means greater side-effects with the minimum score of 0 and the maximum score of 63.

  2. Simpson-Angus Scale in 6 months [6 months]

    Tolerability measures at baseline, at 3rd and 6th months. The cut-off score is 3.

  3. Barnes Akathisia Rating Scale in 6 months [6 months]

    Tolerability measures at baseline, at 3rd and 6th months. The cut-off score is 2.

Other Outcome Measures

  1. QTc interval [6 months]

    Tolerability measures at baseline and 6th months
