PRA-027

This is the first multiple-dose study in humans with PRA-027. This study will provide an assessment of the safety, tolerability, pharmacokinetics (how the drug is absorbed, metabolized and excreted by the body) and pharmacodynamics (a measure of whether the drug is active in the body) of PRA-027 after administration of 28 days of oral doses in women of childbearing potential (cycling) or postmenopausal women.

The primary purpose of this study is to assess the safety and tolerability of ascending single oral doses of PRA-027 in healthy Japanese females. The secondary purpose is to provide the initial pharmacokinetic and pharmacodynamic profiles of PRA-027 in healthy Japanese female subjects.
