The main objective of this clinical trial in randomizing HIV infected patients under good HIV control with tenofovir (TDF), emtricitabine (or lamivudine) plus lopinavir/ritonavir (LPV/r) into switching the regimen to raltegravir (RAL) with darunavir/ritonavir (DRV/r) or continuing the ongoing regimen to compare these two groups' estimated glomerular filtration rate (eGFR) is to investigate whether anti-HIV treatment that does not contain TDF or other reverse-transcriptase inhibitors (NTRI sparing regimen) can be protective of patients' renal functions and has the same virological efficacy in comparison with a standard treatment with TDF, or not.
Eligibility criteria are HIV infected outpatients or inpatients that are:

without history virological failure including protease inhibitors or raltegravir (disregarding whether the patient had a history of drug resistance or drug holiday, or not) taking LPV/r+TVD (or TDF+lamivudine) for longer than 15 weeks before the enrollment with HIV viral load less than 50 copies/ml for 15 weeks, including those with blips (one time episode of detectable level HIV viraemia which are proceeded and followed by undetectable viraemia).

20 years old or older Japanese willing to participate in the trial and able to agree to the informed consent. Main outcome measures are to investigate if the estimated glomerular filtration rate (eGFR) of the intervened group with RAL+DRV/r improves by 10% or more by intention to treat (ITT) analysis at the time of 48 weeks after the start of the trial.

Other outcome measures are:

virological efficacy of the group on DRV/r+RAL (after 48 weeks and up to 96 weeks) comparison of other renal function markers between the two arms: serum creatinine, urine beta-2 microglobulin, tubular resorption rate of phosphate, urine albumin, N-acetyl-beta-glucosaminidase, serum cystatin C, urine protein and urine glucose (after 48 weeks and up to 96 weeks) comparison of lipid markers between the two arms: triglycerides, HDL cholesterol, LDL cholesterol and total cholesterol (after 48 weeks and up to 96 weeks) discontinuation rate of each arm, reason and timing of the discontinuation or the treatment change up to 96 weeks adverse events of each arm, symptoms and rate up to 96 weeks blood plasma concentration level of RAL and DRV of all consented intervened cases at National Center for Global Health and Medicine
