PRIMARY outcome

Timeframe: From baseline to week 24

Population: As-treated: Only participants with either a week 22 CD4+ T-cell count or a week 24 CD4+ T-cell count obtained while receiving MVC without change in background regimen were included.

Change was calculated as the week 24 CD4+ T-cell count (average of the week 22 and week 24 values) minus the baseline CD4+ T-cell count (average of pre-entry and entry values).

The estimated mean change in slopes was summarized across the population by using generalized estimating equations. Pre-treatment CD4+ T-cell counts (from at least 48 weeks prior to study entry) were recorded at screening from patient source documentation. Baseline was defined as the average of pre-entry and entry values. Week 24 was defined as the average of the week 22 and week 24 values.

Timeframe: From baseline through week 24

Population: As-treated: Participants who initiated treatment were included. Follow-up while receiving MVC without change in background regimen were included.

Events with date of onset or specimen date prior to first dose of MVC or after the last dose of MVC were excluded. Signs and symptoms with a date of onset the same as the first dose of MVC were excluded if confirmed by the site to be before the first dose. Lab abnormalities with the date of specimen the same as the date of the first dose of MVC were excluded on the assumption that the specimen was drawn before the first dose. Grading used the Division of AIDS (DAIDS) 2004 Severity of Adverse Events Tables, where Grade 1=Mild, 2=Moderate, 3=Severe, 4=Potentially life-threatening.

0.01 mcg/ml
Interval -0.05 to 0.05

SECONDARY outcome

Timeframe: From week 24 to week 48

Population: As-treated: Only participants that were included in the primary week 24 analysis, i.e. change from baseline to week 24, and with either a week 46 result or a week 48 result obtained while receiving background regimen were included.

Change was calculated as week 48 result (average of week 46 and week 48) minus the week 24 result (average of the week 22 and week 24 values).

Timeframe: At weeks 4, 12, and 24

Population: As-treated: Participants who initiated treatment were included. Follow-up while receiving MVC without change in background regimen were included.

Self-reported MVC adherence data were based on a four-day (8 expected doses) recall. Based on the wording of the Self Report case report form (CRF), participants reporting that they were currently taking MVC that then failed to complete the record of the number of missed doses were assumed to have no missed doses to report. Missing adherence assessments at a time point of interest were ignored and only those participants completing an adherence assessment at least one time point of interest were included.
