E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare transition rates to psychosis during 2 years of follow-up between the omega-3 fatty acids arm and the placebo arm in adolescent subjects who are at risk for developing psychosis. Starting point is the first administration of study medication at the end of visit 2. Endpoint is the moment that a UHR subject makes a transition to psychosis according to the CAARMS criteria, over a period of 2 years.

E.2.2 | Secondary objectives of the trial |
1. Discontinuation rates - comparison between the two arms 2. Tolerability - comparison between the two treatment arms 3. Symptomatology - comparison between the two treatment arms 4. Psychosocial and cognitive function - comparison between the two treatment arms 5. Quality of life - comparison between the two treatment arms 6. Bloodlevels of bioactive lipids - comparison between the two treatment arms 7. (epi)genetic markers - comparison between the two treatment arms 8. Brain structure and function - comparison between the two treatment arms as measured wit Magnetic Resonance Imaging (MRI) 9. Assess the value of MRI and blood parameters as predictive measures for clinical response. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
•Written informed consent of the subject. For individuals younger than 18 years of age the parents / legal representatives need to give consent, and the subject can provide assent (whether the latter is required depends on local laws and regulations). •UHR diagnosis as made using the Comprehensive Assessment of At-Risk Mental States (CAARMS) (Yung et al., 2005). Subjects have to meet one or more of the following criteria: (a) attenuated psychotic symptoms, (b) brief limited intermittent psychotic symptoms (a history of one or more episodes of frank psychotic symptoms that resolved spontaneously within 1 week in the past year), or (c) either the presence of schizotypal personality disorder or a family history of psychosis in a first-degree relative, all three together with a recent decline in function. |
|
E.4 | Principal exclusion criteria |
•Any clinically significant medical condition that may influence the results of the trial or affect the ability to take part in a trial. •Laboratory screening values considered clinically relevant by a medical doctor for transaminases, thyroid hormones or coagulation parameters •Current or past DSM-IV diagnosis of psychosis, as measured with K-SADS-PL •Current treatment with an antipsychotic or mood-stabilising agent •Intake of an antipsychotic or mood-stabilising agent in the two weeks prior to study inclusion •Intake of an antipsychotic agent equivalent to a total haloperidol use of >50 mg in the six months prior to study inclusion •UHR diagnosis on the basis of attenuated psychotic symptoms that are entirely explained by acute intoxication •Current aggression or dangerous behaviour (PANSS G14 score 5 or above) •Current suicidality / self-harm (PANSS G6 score 7) •Current DSM-IV diagnosis of alcohol or substance dependence as measured with K-SADS-PL •Any current or previous neurological disorder, including epilepsy •History of head injury resulting in unconsciousness lasting at least 1 hour •IQ < 70 •More than 4 weeks of regular omega-3 supplementation (>2 daily capsules standard strength providing >600 mg combined EPA/DHA) within the last 6 months.

E.5 End points |
E.5.1 | Primary end point(s) |
The moment that a UHR subject makes a transition to psychosis according to the CAARMS criteria. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The endpoint will evaluated at each study visit. |
|
E.5.2 | Secondary end point(s) |
1. Discontinuation rate [Time Frame: 2 years] [Safety Issue: No] Comparison between the two arms
2. Tolerability [Time Frame: 2 years] [Safety Issue: No] Comparison between the two treatment arms
3. Symptomatology [Time Frame: 2 years] [Safety Issue: No] Comparison between the two treatment arms
4. Psychosocial and cognitive function [Time Frame: 2 years] [Safety Issue: No] Comparison between the two treatment arms
5. Quality of life [Time Frame: 2 years] [Safety Issue: No] Comparison between the two treatment arms
6. Bloodlevels of bioactive lipids [Time Frame: 2 years] [Safety Issue: No] Comparison between the two treatment arms
7. (epi)genetic markers [Time Frame: 2 years] [Safety Issue: No] Comparison between the two treatment arms
8. Brain structure and function [Time Frame: 2 years] [Safety Issue: No] Comparison between the two treatment arms as measured with Magnetic Resonance Imaging (MRI)
9. MRI and blood parameters [Time Frame: 2 years] [Safety Issue: No] The ability of MRI and blood parameters to serve as potential biomarkers that may predict clinical response |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
At the end of the study, the subject sample will be grouped into those who made the transition versus those who did not make the transition to psychosis. The secondary endpoints will be compared at each available timepoint between the 2 groups. |
