Minocycline Augmentation in Schizophrenia

United States120 participantsStarted 2012-02

Plain-language summary

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.
