简要总结
The primary objective of the study is to evaluate the effect of the combination of SGLT2 inhibitor and lifestyle intervention on weight in patients suffering from schizophrenia spectrum disorder on atypical antipsychotics, compared to the combination of placebo and lifestyle intervention.
The secondary objectives of the study include: (i) To evaluate the effect of SGLT2 inhibitor on improving the metabolic traits in patients with schizophrenia spectrum disorder who is taking atypical antipsychotics, compared to the placebo group receiving the same lifestyle intervention. (ii) To compare the safety profile and incidence of adverse events between SGLT2 inhibitor and placebo in patients suffering from schizophrenia spectrum disorder on atypical antipsychotics.
