Primary outcomePrimary: Geometric Mean of C-Trough, of Raltegravir (RAL) at a Dose of 400 mg Twice a Day Plus Darunavir/Ritonavir (DRV/RTV) at a Dose of 800/100 mg Once a Day in HIV-1-infected Patients Were Mesured After 15 Days of Therapy. — 1330; 40; 90 ng/ml — p=<0.01
Summary
While 3-drug regimens remain standard of care, concerns exist regarding the safety of multi-drug regimens taken for a lifetime. Problems with nucleoside analogue therapy prompted successful trials with ritonavir (RTV) boosted PI monotherapy, however long term safety and efficacy of such regimens remains unknown. Clinical trials have shown Raltegravir (RAL) to have potent activity when patients have few active background drugs; it has a superior lipid profile compared with EFV and LPV/RTV. Darunavir/r (DRV) is a potent, well tolerated PI with few GI side effects and lipid disturbances and with a high genetic barrier. The investigators hypothesized that RAL/DRV would be a well tolerated and effective regimen for those patients who are failing nucleoside reverse transcriptase inhibitors based regimens, due to poor tolerability or resistance. The investigators also would like to explore the plasma pharmacokinetics of Raltegravir combined with Darunavir in a sub-group of 12 HIV-infected patients.
