Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment was initiated on 15 APR 2010 and enrolled subjects through 31 JAN 2011. Recruitment and screening took place at 10 participating sites (9 medical clinics and 1 clinical research organization). 43 subjects were enrolled.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
There were 7 participants that did not meet eligibility criteria (either due to disallowed concomitant medication use or safety labs outside of the required parameters). 2 of those 7 subjects re-screened at a later date and were confirmed eligible. 2 subjects withdrew consent after the screening visit but prior to starting the assigned treatment.
