About this study

Primary objective: To evaluate the safety and efficacy of 3 doses of TSE-424 (bazedoxifene acetate), an investigational drug, in comparison with those of placebo and raloxifene in preventing osteoporosis in postmenopausal women.

Secondary objective: To evaluate the effect of TSE-424 (bazedoxifene acetate), an investigational drug, in comparison with that of placebo and raloxifene on endometrium, metabolic parameters, vasomotor symptoms, adverse events, and quality of life. Samples will be collected for population pharmacokinetic (PK) analysis.
