| Study summary: |
|
The study is a randomized, double blind, multicenter, placebo controlled, parallel group,
proof of concept study comparing the efficacy, safety, and acceptability of 3 doses of S
equol to placebo in menopausal patients with vasomotor symptoms. The study objective is an
evaluation of the dose response of 3 dose levels of AUS 131 (S equol) and placebo with
respect to reducing the mean number of moderate to severe vasomotor symptoms after 4 weeks
of treatment. The safety of S-equol will be evaluated during the study. |
