Participant Flow
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. |

Hide Outcome Measure 4| Measure Type | Secondary |
|---|---|
| Measure Title | Change in Quality of Life From Baseline to 48 Weeks of Study Treatment |
| Measure Description | Quality of Life was measured by self report using a standardized scale, where 0 is death and 100 is perfect health. The baseline measure was obtained prior to initiation of study treatment arm. The week 48 measure captures Quality of Life by self report at 48 weeks of study treatment. |
| Time Frame | baseline and 48 weeks |
| Safety Issue | No |
Population Description
| Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate. |
|---|
| Data for all participants assigned to a study treatment was analyzed except data for participants that did not have both baseline and week 48 data, including early withdrawal, virologic failure, loss to follow-up or missing data. |
