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.

The main limitation of our study is that it is a single-arm PK study and, thus, the effect of the introduction or withdrawal of one drug over the other cannot be compared.

| OG000 | Single Arm With Dual Therapy | Fifteen patients were screened and enrolled, and all of them completed the study procedures. The treating physician chose an NRTI-sparing regimen because of toxicity or resistance mutations to NRTIs, which included DRV/RTV 800/100 mg once daily plus RAL 400 mg twice daily. Inclusion criteria were HIV-1-infected patients, receiving a NRTI-based regimen, naive to RAL, with no evidence of PI mutations by genotype test, and signed informed consent forms. All doses of RAL were administered in the morning and evening, orally with food (light meal). Patients were admitted to the hospital in the morning on day 15 and stayed for 12 hours after the last administration of RAL. The morning dose of RAL and DRV/ RTV was administered in the clinic with a light breakfast (200 mL of whole milk and a ham and cheese sandwich), and blood samples were drawn immediately before breakfast and 0.5 1, 2, 3, 4, 6, 8, 12, and 24 hours afterward |
