Primary Outcome Measures:
  • The percent change from baseline in lumbar spine bone mineral density (BMD) after 24 months. [ Time Frame: 24 months ]

Secondary Outcome Measures:
  • Additional BMD evaluation including total hip, femoral neck and trochanter at months 6, 12, 18 and 24. Serum bone markers at months 3, 6, 9, 12, 18 and 24. Lipid panel at months 3, 6, 12, 18 and 24. [ Time Frame: Up to 24 months ]

Enrollment: 1742
Study Start Date: July 2001
Study Completion Date: September 2004
Primary Completion Date: July 2004 (Final data collection date for primary outcome measure)
Detailed Description:

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.
