Minocycline Augmentation in Schizophrenia
Status unconfirmed · Not applicable · Has a placebo group
Conditions studied: Schizophrenia
In brief
This study aims to examine the efficacy of minocycline augmentation in a sample of moderately ill outpatients with early-course schizophrenia on their chlorpromazine-equivalent doses of second-generation antipsychotic medications. The investigators hypothesize that as compared to placebo a 2-month treatment with minocycline in 120 volunteers with early-course schizophrenia will result in a more significant improvement in psychopathology (primary outcome) and cognitive symptoms (secondary outcome). In addition, cytokine plasma levels will be used as another secondary outcome measure to see if treatment-induced changes in total PANSS score are associated with changes in cytokine levels.
