E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Different lines of evidence now suggest that low grade inflammation in the central lines of the central nervous system is involved in the pathogenesis of schizophrenia. Such inflammation could cause increased gray matter loss and consequently contribute to more severe negative and cognitive symptoms. We propose to investigate the effect of administering prednisolone (a broad-acting, potent immune suppressive agent) versus placebo, on psychotic symptoms, in addition to standard antipsychotic medication in patients with early stage schizophrenia or related disorders. This may revent neuronal damage caused by low-grade inflammatory rocesses in the brain. It is expected that symptom severity will be improved with prednisolone use. |
Verschillende onderzoekslijnen suggereren dat lage ontstekingsgraad in het centraal zenuwstelsel betrokken is bij de pathogenese van schizofrenie. Een dergeijke ontsteking zou het verlies van grijze cellen kunnen vergroten en via deze weg bijdragen aan ernstigere negatieve en cognitieve symptomen. Middels deze studie willen we onderzoeken wat het effect is van prednisolon (een breed-werkende, potente immuunsuppressor) versus placebo op psychotische symptomen, naast de standaardbehandeling bij patiënten in een vroege fase van schizofrenie of een gerelateerde stoornis. Deze behandeling zou neuronale schade, veroorzaakt dor een lage ontstekingsgraad in de hersenen, kunnen voorkomen. We verwachten dat de ernst van de symptomen zal afnemen bij prednisolon gebruik. |

E.2.2 | Secondary objectives of the trial |
Secondary objectives concern the comarison of the 2 groups with regards to changes in:
- Positive and Negative Symptom Scale (PANSS) subscales
- Cognitive performance (Brief Assesssment of Cognition in Schizophrenia; BACS)
- General functioning (Global Assessment of Functioning)
- Depressive symptoms (Calgary Depression Scale for Schizophrenia)
- Safety data will be evaluate by comparing incidences (number and % of subjects with at least one occurrence) of key SAEs and SUSARs (e.g. hospitalisations) |
Secundaire objectieven vergelijken de 2 groepen met betrekking tot veranderingen op:
- Positve and Negative Symptom Scale (PANSS) subschalen
- Cognitief functioneren (Brief Assesssment of Cognition in Schizophrenia; BACS)
- Algemeen functioneren (Global Assessment of Functioning)
- Depressieve symptomen (Calgary Depression Scale for Schizophrenia)
- Veiligheidsdata worden geëvalueerd door de incidentie te vergelijken (aantal en percentage van deelnemers waarbij events voorkomen) wat betreft belangrijke SAEs en SUSARs (bijvoorbeeld: hospitalisatie) |
