Eligibility Criteria
Inclusion Criteria: - Human immunodeficiency virus-1 (HIV-1) infected participants on their first-line treatment with highly active antiretroviral therapy (HAART) (combination of 2 or 3 nucleoside reverse transcriptase inhibitors [NRTIs] with at least 1 additional antiretroviral [ARV] from the non-nucleoside reverse transcriptase inhibitor [NNRTI] and/or protease inhibitors [PI] class) for at least 24 weeks, provided the same ARV combination for at least 8 weeks before screening
- Participants' preference for a more convenient regimen and/or any current or history of toxicity on actual regimen
- Plasma HIV-1 ribonucleic acid (RNA) less than 50 cp/ml for at least 24 weeks before screening, where single viral blips of more than 50 copies/mL are allowed
- Cluster of differentiation 4 (CD4) count more than 100/mm3 at the start of HAART and more than 200/mm3 at screening
- Healthy on the basis of physical examination, medical history, vital signs, clinical laboratory tests, and 12-lead electrocardiogram performed at screening
- Agrees to protocol-defined use of effective contraception
- Postmenopausal, surgically sterile, or abstinent female participants
Exclusion Criteria
- History of coronary heart disease, uncontrolled hypertension, peripheral vascular disease and or cerebrovascular disease
- History of virological failure on highly active antiretroviral therapy, plasma HIV-1 ribonucleic acid more than 500 copies/mL after initial full virological suppression while on ARV therapy and any PI mutations
- Participants with significantly hepatic and liver insufficiency or diagnosed with acute viral hepatitis or have active clinically significant diseases and acquired immune deficiency syndrome (AIDS) defining illness at screening
- Current significant tobacco use, active drug or alcohol use or dependence
- Use of lipid-lowering drugs within 4 weeks prior to study entry and use of testosterone, anabolic steroids, oral contraceptives or hormonal replacement within 12 weeks prior to study entry or previous or current use of darunavir
- Use of systemic glucocorticoids, long-acting inhaled steroids (inhaled via mouth or nose), or other immunomodulators within 30 days prior to study entry
