Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether TSE-424 (bazedoxifene acetate), an investigational drug, is safe and effective in the prevention of osteoporosis in postmenopausal women.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
