E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Compare the clinical effectiveness of amisulpride, aripiprazole, and olanzapine, in patients with schizophrenia and related psychotic disorders, in a head-to-head pragmatic, randomized trial funded independently of the pharmaceutical industry; and , through a translational approach, to link drug-induced changes in symptoms, neurocognitive functioning and side effects, to changes in biological substrates on neurochemical, functional and structural levels. . |
|
E.2.2 | Secondary objectives of the trial |
In the randomized, head-to-head design, among the IMPs:
1. Compare the drugs with regards to cognitive functions localized in prefrontal cortex and the corresponding brain activation, change of cortical thickness, and myelin sheath regeneration.
2. Compare effects on mood symptoms and suicidal behaviour.
3. Compare akathisia by objective measurements.
4. Compare heart rate variability.
5. Compare antipsychotic-induced differential gene expression related to lipid metabolism in patients.
6. Compare inflammation markers associated with cardiovascular disease and general inflammation.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary end point will be differences among the treatment groups with regards to change of the PANSS positive subscale score at 12 months.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
The secondary end points will be differences among the treatment groups with regards to the following outcome measures:
The patients will be tested at baseline and thereafter at weeks 1, 3, 6; months 3,6, 9, and 12 after baseline.
The other assessment include:
5.2 Assessments at baseline
5.2.1 General Demographics, prior/ present mental/ physical illness, drug/ alcohol/ smoke.
5.2.2 Diagnostics SCID1 diagnostic interview
5.3 Repeated assessments (baseline; weeks 1,3,6; months 3,6,9,12)
5.3.1 Physical Blood pressure, Body mass index (BMI), waist and hip ratios.
5.3.2 Psychometric tools/ side effect rating scales The Positive And Negative Syndrome Scale; The revised Beliefs About Voices Questionnaire; The Calgary Depression Scale for Schizophrenia; The Clinical Global Impression Scale – Severity of illness; The Global Assessment of Functioning scale – Split version ; the Drake Scale (the alcohol and drug use scale); AUDIT/ DUDIT; The UKU Side Effect Rating Scale; Insight scale; Suicide scale; Young Mania Scale
5.3.3 Neurocognitive tests
The battery includes tests of executive functioning and attention/working memory, assessing functions localized to frontal brain regions more likely to be influenced by medication effects.
