FAS included all the randomized participants who had taken at least one dose of the study medication. Missing data was imputed as "failure" which was defined as not meeting the criteria of less than 400 copies/mL or with at least 0.5 log10 decrease from baseline of HIV-1 RNA levels.

  Description
Maraviroc QD Maraviroc 150 or 300 milligrams (mg) tablet orally once daily (QD) in the evening, dose adjusted according to the other prescribed drugs taken by participants as part of optimized background therapy (OBT) selected according to local standard of care (3 to 6 drugs based on resistance testing, treatment history and safety considerations). Placebo matched to maraviroc tablet orally in the morning.
Maraviroc BID Maraviroc 150 or 300 mg tablet orally twice daily (BID) in the morning and evening, dose adjusted according to the other prescribed drugs taken by participants as part of OBT selected according to local standard of care (3 to 6 drugs based on resistance testing, treatment history and safety considerations).

18.  Secondary:   Change From Baseline in Viral Load at Week 24 and Week 48 by Overall Susceptibility Score (OSS) at Screening   [ Time Frame: Baseline, Week 24 and Week 48 ]

Measure Type Secondary
Measure Title Change From Baseline in Viral Load at Week 24 and Week 48 by Overall Susceptibility Score (OSS) at Screening
Measure Description Association between baseline resistance and virological response was assessed as change in viral load by OSS at screening. OSS categorized as 0, 1, 2, >3 (maximum value of 6) and calculated as the sum of the net assessment of in-vitro phenotypic and genotypic susceptibility using a binary scoring system (0= resistant, 1= sensitive or susceptible) for each antiretroviral agent in OBT. Higher scores indicate greater susceptibility. Baseline value is the average of the values from screening, randomization and immediately pre-dose.
Time Frame Baseline, Week 24 and Week 48  
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.
FAS; 'N' (number of participants analyzed) is signifying those participants who were evaluable for this measure. 'n' is number of participants with given OSS score at screening for each treatment arm measured at particular time-point. LOCF was used to impute missing values.

Reporting Groups
  Description
Maraviroc QD Maraviroc 150 or 300 milligrams (mg) tablet orally once daily (QD) in the evening, dose adjusted according to the other prescribed drugs taken by participants as part of optimized background therapy (OBT) selected according to local standard of care (3 to 6 drugs based on resistance testing, treatment history and safety considerations). Placebo matched to maraviroc tablet orally in the morning.
Maraviroc BID Maraviroc 150 or 300 mg tablet orally twice daily (BID) in the morning and evening, dose adjusted according to the other prescribed drugs taken by participants as part of OBT selected according to local standard of care (3 to 6 drugs based on resistance testing, treatment history and safety considerations).
Placebo Placebo matched to maraviroc tablet orally BID in the morning and evening, in combination with OBT selected according to local standard of care (3 to 6 drugs based on resistance testing, treatment history and safety considerations).
