E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this trial is to investigate the beneficial effect of raloxifene as compared to placebo when given for twelve weeks in addition to antipsychotic medication. We expect to find lower symptom severity as measured with the Positive And Negative Symptom Scale (PANSS) over the course of twelve weeks. |
Het primaire doel van deze studie is het effect van raloxifene onderzoeken in vergelijking met placebo bij toediening gedurende twaalf weken naast antipsychotische medicatie. We verwachten een lagere ernst van de symptomen zoals gemeten met de Postive and Negative Symptom Scale (PANSS). |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives concern change in functional outcome (PSP), change in negative symptoms (BNSS), change in cognitive symptoms (BACS), change in severity of thought disorder (using the Thought And Language Disorder scale, TALD), change in health-related quality of life and quality adjusted life years (QALY) outcomes using the EQ-5D, change in cognitive control (Stroop Test), change in use of healthcare and non-healthcare resources, change in comorbid depression will be monitored using Beck’s Depression Inventory (BDI), change in productive language tested by analyzing speech recordings, change in psychophysiological parameters of basic information processing will be assessed through an electroencephalogram (EEG, i.e. N100 and P300). Hormone- and deoxyribonucleic acid (DNA)-profiles will be used to analyze the efficacy of raloxifene augmentation in different groups. |
Secundaire doelstellingen zijn verandering in functionele uitkomst (PSP), verandering in negatieve symptomen (BNSS), verandering in cognitie (BACS), verandering in formele denkstoornissen gemeten met de Thought And Language Disorder scale (TALD), verandering in gezondheidsgerelateerde kwaliteit van leven en de kwaliteit gecorrigeerde levensjaren (QALY) resultaten, verandering in het gebruik medische en niet-medische middelen, verandering in comorbide depressie met behulp van Beck's Depression Inventory (BDI), verandering in cognitieve controle gemeten d.m.v. een Stroop Test, verandering in productieve taal getest door het analyseren van spraakopnames, verandering in psychofysiologische parameters van basisinformatieverwerking d.m.v. een elektro-encefalogram (EEG). Hormoon- en DNA-profielen worden gebruikt om de effectiviteit van raloxifeenaugmentatie te bepalen in verschillende groepen. |
