Bazedoxifene -Treatment for Women With Schizophrenia

2019-10-09 09:21:39 | BioPortfolio


To study the effect of adjunctive bazedoxifene - a selective estrogen receptor modulator (SERM) in a double blind, placebo-controlled adjunctive study in the treatment of women with schizophrenia. All patients receive standardized antipsychotic medication.


Despite advances in the treatment of schizophrenia, pharmacotherapy remains sub- optimal, and the prognosis for many patients is poor. We have pioneered work showing that estradiol has a positive role in the treatment of psychosis symptoms and cognitive deficits seen in people with schizophrenia. However, with the longer-term work from studies such as the Women's Health Initiative (1), it has become clear that long-term use of estradiol with progesterone may have associated increased risks of breast and other cancers. Hence, we began working with the Selective Estrogen Receptor Modulator - raloxifene, which appears to be safer for longer term use with respect to the development of breast and other cancers. Building on our and others work, raloxifene used as an adjunctive treatment in schizophrenia appears to produce inconsistent and varying responses in different sub-populations; gender, menopausal status, age, drug dose and delivery mode. We now propose to conduct a double-blind, randomized, placebo controlled trial of a third generation SERM - bazedoxifene - which is 4 times more selective for the alpha than the beta oestrogen receptor subtype. Bazedoxifene 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 160 women to determine if bazedoxifene, as an adjunctive hormone modulator, is effective for positive and cognitive symptoms of schizophrenia.

A chronic form of schizophrenia characterized primarily by the presence of persecutory or grandiose delusions, often associated with hallucination.

Megestrol acetate is a progestogen with actions and uses similar to those of the progestogens in general. It also has anti-androgenic properties. It is given by mouth in the palliative treatment or as an adjunct to other therapy in endometrial carcinoma and in breast cancer. Megestrol acetate has been approved to treat anorexia and cachexia.
