Pooled Analysis of the Effects of Conjugated Estrogens/Bazedoxifene on Vasomotor Symptoms in the Selective Estrogens, Menopause, and Response to Therapy Trials

Conjugated estrogens/bazedoxifene (CE/BZA) reduced menopause-related hot flashes (HFs) in the Selective estrogens, Menopause, And Response to Therapy (SMART) trials. This post hoc pooled analysis of SMART-1 and -2 further characterized effects of CE/BZA on HFs in the overall population and patient subgroups. Data from two randomized, double-blind, placebo- and active-controlled, phase 3 studies were pooled for nonhysterectomized postmenopausal women with moderate/severe HFs given CE 0.45 mg/BZA 20 mg, CE 0.625 mg/BZA 20 mg, or placebo for 12 weeks. HF frequency and severity were assessed by daily diary. The pooled analysis included 403 participants. At 12 weeks, CE 0.45 mg/BZA 20 mg and CE 0.625 mg/BZA 20 mg significantly (all p 5 years) versus early menopause (≤5 years). CE/BZA effectively reduces moderate/severe HFs in postmenopausal women.
