Description of intervention(s) / exposure
Treatment: Drugs - Darunavir (DRV)
Treatment: Drugs - Ritonavir (rtv)

Experimental: DRV/rtv 800/100 mg once daily - Two 400 mg darunavir (DRV) ie, TMC114 tablets + one 100 mg ritonavir (rtv) capsule once daily.

Experimental: DRV/rtv 600/100 mg twice daily - One 600 mg TMC114 tablet + one 100 mg capsule of rtv twice daily.


Treatment: Drugs: Darunavir (DRV)
DRV/rtv 800/100 mg once daily group: 2 tablets of 400 mg of DRV administered orally once daily. DRV/rtv 600/100 mg twice daily group: 1 tablet of 600 mg DRV administered orally twice daily.

Treatment: Drugs: Ritonavir (rtv)
DRV/rtv 800/100 mg once daily group: One capsule of 100 mg of ritonavir administered orally once daily. DRV/rtv 600/100 mg twice daily group: One capsule of 100 mg of ritonavir administered orally twice daily.

Eligibility
Key inclusion criteria
* Patients with documented human immunodeficiency virus - Type 1 (HIV-1) infection
* Patients with a viral load greater than 1,000 HIV-1 ribonucleic acid (RNA) copies/mL
* Stable highly active antiretroviral therapy (HAART) regimen for at least 12 weeks at screening
* In the investigator's opinion, non-nucleoside reverse transcriptase inhibitors (NNRTIs) are not a valid treatment option, because of the patient's antiretroviral (ARV) treatment history, ARV resistance testing, medication-taking behavior, safety and tolerability concerns, or other patient-related factors
* Prescreening or/and screening plasma HIV-1 RNA greater than 1,000 copies/mL on HAART regimen at screening
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Presence of any currently active conditions that fit the definition of the World Health Organization (WHO) Clinical Stage 4, with the following exceptions: stable cutaneous kaposi's sarcoma (ie, no internal organ involvement other than oral lesions) that is unlikely to require any form of systemic therapy during the study time period, wasting syndrome
* Patients for whom an investigational ARV is part of the current regimen, with the following exceptions if applicable (depending on local regulatory approval): tenofovir, emtricitabine
* Previous or current use of enfuvirtide (ENF), tipranavir and/or DRV
* Life expectancy of less than 12 months
* Pregnant or breast-feeding females
* Any active clinically significant disease (eg, tuberculosis [TB], cardiac dysfunction, pancreatitis, acute viral infections) or findings during screening of medical history or physical examination that, in the investigator's opinion, would compromise the patient's safety or outcome of the study

Summary
Brief summary
The purpose of this study is to test if being treated with darunavir/ritonavir (DRV/rtv) 800/100 mg daily is as effective as being treated with DRV/rtv 600/100 mg twice daily, in early antiretroviral (ARV)-experienced patients when given along with selected optimized background regimen (OBR).
