Summary
Brief summary
Despite advances in the treatment of schizophrenia, pharmacotherapy remains sub-optimal, and the prognosis for many patients is poor. Estradiol has a positive role in the treatment of psychosis symptoms and cognitive deficits seen in people with schizophrenia, but it has become clear that long-term use of estradiol with progesterone may have associated increased risks of breast and other cancers. Bazedoxifene, a third generation Selective Estrogen Receptor Modulator (SERM), appears to be safer with respect to long term use than older SERMs, has additional actions on the glucocorticoid receptor, and together this different pharmacology speculatively has greater potential than other SERMs to impact favorably on both psychosis symptoms and cognition in men and women with schizophrenia. This study will test 100 men to determine if bazedoxifene, as an adjunctive hormone modulator, is effective for positive and cognitive symptoms of schizophrenia. We hypothesise that bazedoxifene will significantly reduce psychopathology and will significantly improve cognition.
