Primary Outcome Measures:

To determine the effect of single and multiple oral doses of CORLUX on the pharmacokinetics of a single oral dose of fluvastatin administered to healthy volunteers. [ Time Frame: 8, 9, 12, 13, 14, & 15 days ] [ Designated as safety issue: No ]

Estimated Enrollment:	20
Study Start Date:	September 2008
Study Completion Date:	November 2008
Primary Completion Date:	November 2008 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Experimental	Drug: mifepristone + fluvastatin Subjects will receive a single oral dose of 40 mg PO of fluvastatin on three occasions: alone (Day 1), at the same time as a single dose of CORLUX 1200 mg (Day 8) and during concomitant administration of CORLUX 1200 mg/day (CORLUX on Days 8-14, fluvastatin on Day 14).

Detailed Description:

This is a fixed-sequence, drug-drug interaction study in healthy volunteers lasting up to a total of 9 weeks: up to 4 weeks screening, approximately 2 weeks for dosing (including a 1-week washout between periods), and approximately 3 weeks of a drug-free interval until termination. The purpose of this study is to determine the effect of single and multiple oral doses of CORLUX on the pharmacokinetics of a single oral dose of fluvastatin administered to healthy volunteers.

History of an allergic reaction to mifepristone or fluvastatin
Positive serum test for human immunodeficiency virus (HIV), hepatitis B virus or hepatitis C virus
Blood donation within 30 days of dosing
