Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 312
Healthy volunteers: no

Brief summary:
The primary purpose of this study is to assess the rate of early discontinuation from randomized Human Immunodeficiency Virus (HIV) Postexposure Prophylaxis (PEP) for any reason other than confirmation of the negative HIV infection status of the index person in patients receiving HIV PEP for at least 28 and a maximum of 30 days.

Detailed description:
This is a randomized (study medication assigned by chance), open-label (all people involved know the identity of the intervention), active-controlled (patients are assigned to either a recognized effective treatment or the study medication), parallel-group (each treatment group will be treated at the same time), multicenter study comparing DRV/r PEP (DRV/r administered with 2 NRTIs selected at the discretion of the investigator) to standard of care PEP (as per German-Austrian guidelines) in patients at risk of HIV infection due to HIV exposure through occupational injury and non-occupational exposure. This study consists of screening period, treatment period and a follow up period. HIV PEP will be administered for a total of at least 28 days and maximum of 30 days during treatment period, including any prestudy HIV PEP initiated before screening. Approximately 318 patients will be screened and enrolled to ensure that at least 131 patients are randomly assigned to receive DRV/r PEP or standard of care PEP. Safety will be evaluated during the entire study period. Data relating to a patient's functional impairment in conjunction with HIV PEP will be collected on Day 1 as baseline data, and further on Days 14 and 28 as well as at Month 3.

Arms:
arm 1: DRV/r 800/100 mg q.d. with 2 NRTIs: darunavir (800 mg) in combination with low-dose ritonavir (100 mg) administered once a day for at least 28 days and a maximum of 30 days along with 2 nucleoside/nucleotide analogue reverse transcriptase inhibitors (NRTIs). arm 2: Comparator standard of care HIV PEP (as per German-Austrian Guidelines): Administration of the standard of care HIV PEP (postexposure prophylaxis) consisting of 2 NRTIs plus third partner.

Interventions: intervention 1: Darunavir/Ritonavir (DRV/r) intervention 2: Lopinavir in fixed combination with Ritonavir intervention 3: Zidovudine intervention 4: NRTIs intervention 5: Efavirenz
Intervention descriptions: intervention 1: Darunavir (DRV) type=exact number, unit=mg, number=800, form=tablet, route=oral use. Tablet is taken once a day, for 28 days; Ritonavir (r) type=exact number, unit=mg, number=100, form=tablet, route=oral use. Tablet is taken once a day, for at least 28 days and a maximum of 30 days. intervention 2: type=exact number, unit=mg, number=400/100, form=tablet, route=oral use. Tablet is taken once or twice a day, for at least 28 days and a maximum of 30 days. intervention 3: type=exact number, unit=mg, number=250, form=tablet, route=oral use. Tablet is taken twice a day, for at least 28 days and a maximum of 30 days. intervention 4: The NRTIs (including tenofovir/emtricitabine \[Truvada\], lamivudine/zidovudine \[Combivir\]) will be administered as per the individual Summary of Product Characteristics (SmPCs) at the discretion of either the treating physician or Investigator. intervention 5: type=exact number, unit=mg, number=600, form=tablet, route=oral use. Tablet is taken once a day, for at least 28 days and a maximum of 30 days.
