Schizophrenia Clinical Trial
Official title:
Agomelatine Treatment of Major Depressive Episodes in the Course of Schizophrenic Psychoses (AGOPSYCH)
Major depressive episodes (MDEs) occur frequently during the course of psychotic disorders, and several antidepressive agents have been successfully applied. The new melatonergic antidepressant agomelatine (AGO) appears promising for the treatment of MDEs in schizophrenia for several reasons. The investigators plan to test the efficacy and tolerability of AGO for antidepressive treatment in schizophrenia. For this task, the investigators plan to enrol 27 schizophrenic patients into an open, single-armed, prospective clinical trial with agomelatine.
Major depressive episodes (MDEs) occur frequently during the course of psychotic disorders, and several antidepressive agents have been successfully applied. The new melatonergic antidepressant agomelatine (AGO) appears promising for the treatment of MDEs in schizophrenia for several reasons: 1. AGO provides a unique pharmacological profile by combining antidepressive potency, sleep regulation and enhancement of frontocortical dopaminergic activity by 5-HT-2C-blockade. 2. AGO might exert favourable effects on cognition. 3. While pharmacokinetic interactions are generally possible, major influences on antipsychotic substances are unlikely due to metabolism by cytochrome isoenzymes CYP1A2 and CYP2C9/19. 4. AGO is characterized by a favourable range of adverse events (AE) which do not overlap with typical antipsychotic AEs such as weight gain and sexual dysfunction. Thus, the risk of additive effects seems to be small. The investigators plan to enroll 27 schizophrenic patients into an open, single-armed, prospective clinical trial with agomelatine. As predefined primary and secondary endpoints, we are going to investigate whether AGO is able to improve MDE severity, sleep quality, general and psychosocial functioning as well as cognitive function in schizophrenia without detrimental effects on the psychotic syndrome. Moreover, we intend to monitor for pharmacokinetic interactions. The results obtained will allow designing future randomized and controlled clinical trials in order to improve the range of therapeutic options for affective and cognitive deficits in schizophrenia. ;
