Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Amisulpride open label
Treatment: Drugs - 6-week amisulpride double blind treatment
Treatment: Drugs - 6-week olanzapine double blind treatment
Treatment: Drugs - 12-week clozapine open-label treatment
BEHAVIORAL - Psychosocial intervention

Other: Phase I: 1 arm 'amisulpride open label' - For 4 weeks, all patients will be treated with amisulpride open label.

Active comparator: Phase II: 'amisulpride double blind' - Patients who do not meet remission criteria during phase I (4 weeks open label amisulpride), flow to phase II where they are randomised to 1 of 2 6-week double blind treatment arms, one of which is 'amisulpride double blind'

Active comparator: Phase II 'olanzapine double blind' - Patients who do not meet remission criteria during phase I (4 weeks open label amisulpride), flow to phase II where they are randomised to 1 of 2 6-week double blind treatment arms, one of which is 'olanzapine double blind'

Other: Phase III: 1 arm 'clozapine open label' - Patients who do not meet remission criteria during phase II (6-week double blind amisulpride vs olanzapine), flow to phase III, where only 1 arm is available: 'clozapine open label'

Experimental: Psychosocial intervention - Patients who meet remission criteria during any of the phases of the medication component, patients who drop out of the medication component and patients who did not meet remission criteria at the end of the medication component, will flow to the psychosocial intervention component, where they are randomised to 1 of 2 arms, one of which is the 'Psychosocial Intervention' arm.

No intervention: Psychosocial Intervention phase: 'TAU' - Patients who meet remission criteria during any of the phases of the medication component, patients who drop out of the medication component and patients who did not meet remission criteria at the end of the medication component, will flow to the psychosocial intervention component, where they are randomised to 1 of 2 arms, one of which is the 'Treatment as usual' arm.
