Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Percentage of Participants Achieving HIV-1 Ribonucleic Acid (RNA) <50 Copies/mL of Plasma at Week 192	The percentage of participants achieving HIV-1 ribonucleic acid (RNA) <50 copies/mL in plasma at Week 192 was calculated. The Abbott RealTime HIV-1 Assay, which has a lower limit of reliable quantification (LoQ) of 40 copies/mL, was used to measure the HIV-1 RNA level in plasma samples obtained at Week 192 visit.	Week 192
Other	Percentage of Participants Achieving HIV-1 Ribonucleic Acid (RNA) <40 Copies/mL of Plasma at Week 192	The percentage of participants achieving HIV-1 ribonucleic acid (RNA) <40 copies/mL in plasma at Week 192 was calculated. The Abbott RealTime HIV-1 Assay, which has a lower limit of reliable quantification (LoQ) of 40 copies/mL, was used to measure the HIV-1 RNA level in plasma samples obtained at Week 192 visit. Participants with reading below the LoQ were considered to have <40 copies/mL.	Week 192
Other	Change From Baseline in CD4 Cell Count at Week 192	The change from baseline in CD4 cell count at Week 192 was calculated.	Baseline (Day 1) and Week 192
Primary	Percentage of Participants Achieving HIV-1 Ribonucleic Acid (RNA) <50 Copies/mL of Plasma at Week 48	The percentage of participants achieving HIV-1 ribonucleic acid (RNA) <50 copies/mL in plasma at Week 48 was calculated. The Abbott RealTime HIV-1 Assay, which has a lower limit of reliable quantification (LoQ) of 40 copies/mL, was used to measure the HIV-1 RNA level in plasma samples obtained at Week 48 visit.	Week 48
Primary	Percentage of Participants Experiencing =1 Adverse Events (AE) up to Week 48	The percentage of participants experiencing =1 AE up to Week 48 was calculated. An AE was defined as any unfavorable and unintended sign, symptom, or disease (new or worsening) temporally associated with the use of study therapy, regardless of whether or not a causal relationship with the study therapy could be determined.	Up to Week 48

Secondary	Change From Baseline in CD4 Cell Count at Week 96	The change from baseline in CD4 cell count at Week 96 was calculated.	Baseline (Day 1) and Week 96
Secondary	Time to Loss of Virologic Response	The time to loss of virologic response (TLOVR) was reported. For participants who achieved HIV-1 RNA <50 copies/mL of plasma and subsequently had two consecutive HIV-1 RNA values of =50 copies/mL measured at least 1 week apart, TLOVR was the time between Day 1 and the date of the first of the two consecutive values =50 copies/mL. For participants who achieved and sustained HIV-1 RNA <50 copies/mL, time to loss of virologic response was censored at the time of the last available measurement.	Up to Week 96
