Human Immunodeficiency Virus - Type 1 Clinical Trial
Official title:
A Randomized, Open-label Trial to Compare the Efficacy, Safety and Tolerability of DRV/Rtv (800mg/100mg) q.d Versus DRV/Rtv (600mg/100mg) b.i.d in Early Treatment-experienced HIV-1 Infected Subjects
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).
This is a randomized (the study medication is assigned by chance), open-label (all people know the identity of the intervention) study in which 590 patients will be randomly assigned to receive either DRV/rtv 800/100 mg daily or DRV/rtv 600/100 mg twice daily along with the selected OBR. An OBR will consist of at least 2 nucleoside reverse transcriptase inhibitors (NRTIs) selected by the investigator. The study will include a 4 week screening period, 48-weeks of treatment period and 4-weeks of follow-up. The study will also consists of extension phase after Week 48: in regions where DRV is not yet commercially available or reimbursed by the health care system, patients who complete the 48 weeks of treatment with DRV/rtv and who continue to benefit from this treatment, will have the opportunity to continue DRV treatment as a 600 mg twice daily dosage until DRV is reimbursed and available via the public and/or private health care system or until its development is discontinued. Safety evaluation will consists of adverse events (including specific toxicities), clinical laboratory tests, vital signs, electrocardiogram, physical and skin examination. ;
