CE/BZA effects on bone and quality of life in European postmenopausal women: a pooled analysis

AbstractObjectives: To evaluate the efficacy of conjugated estrogens/bazedoxifene (CE/BZA) on bone mineral density (BMD), bone turnover markers (BTM), and menopause-specific quality of life (MENQOL) in European women.Methods: Data through 12 months were pooled from two double-blind, randomized, controlled trials in non-hysterectomized postmenopausal women who received CE/BZA or placebo. Women from European study sites with evaluable BMD (n = 60), BTM (n = 56), and MENQOL questionnaire (n = 236) data were included and compared with 1523 women from US study sites (n = 730 with evaluable data for bone outcomes).Results: At month 12, CE 0.45 mg/BZA 20 mg and CE 0.625 mg/BZA 20 mg, respectively, significantly improved BMD (adjusted difference vs. placebo) in lumbar spine (2.5%, 2.9%; both p ≤ 0.011) and total hip (1.7%, 2.2%, both p ≤ 0.002), significantly improved serum BTMs (osteocalcin: –31.1%, –33.1%; C-telopeptide: –48.5%, –36.8%) vs. placebo (osteocalcin: 6.7%, C-telopeptide: 4.2%; all p < 0.001), and si...
