About this trial

In following guidelines for studying negative symptoms in schizophrenia, 60 patients aged 18-40, diagnosed with schizophrenia or schizoaffective disorder during the last ten years, will receive a combination of the iron chelator DFP plus NAC or a matching placebo plus NAC combination, as add-on to their maintenance antipsychotic drug (APD) treatment, for a duration of 36 weeks. Prior to initiation of treatment, all participants will undergo baseline MRI scan. A follow-up MRI will be conducted at the end of the 36-week study period, or upon early withdrawal if applicable, to evaluate the effect of the add-on treatment on iron dyshomeostasis and morphology.
