Beskrivelse
Inclusion Criteria:
- Asymptomatic HIV-1 infected male and patients aged 18-55 years inclusive.

Change From Baseline in Human Immunodeficiency Virus-1 (HIV-1) Viral Load at Day 8
Tidsramme: Baseline, Day 8
|
Change from baseline in log 10-transformed plasma viral load(Human Immunodeficiency Virus-1 Ribonucleic Acid[HIV-1 RNA]) levels(log10 copies/milliliter[copies/mL])reported.Viral load determined using reverse transcriptase-polymerase chain reaction(RT-PCR) assay with standard lower limit of detection(LLOD) 400 copies/mL.For samples with reading less than (<)400 copies/mL,assay repeated using ultra sensitive method with LLOD of 50 copies/mL.Values below limit of quantification(LOQ) 50 copies/mL set to 50 copies/mL.Baseline was mean of three pre-dose values taken at screening,randomization,Day 1.

Number of Participants With Time to Rebound of Human Immunodeficiency Virus (HIV) Viral Load
Tidsramme: Day 8 up to Follow-up (Day 38 to 40 [31 to 33 days post-last dose])
|
Time to rebound of viral load was defined as time from the last dose (Day 8) to the time of the first occasion at which the viral load was greater than baseline value.
Number of participants with rebound of viral load at specified number of days after last dose (day 8) was reported.
