The objective of antiretroviral therapy (ART) is the maintenance of HIV viral suppression, the optimal condition to prevent disease progression, to optimize immune restoration, to prevent the development of viral resistance and to reduce viral transmission. Antiretroviral therapy has to be maintained long life over decades in the absence of strategies for HIV cure. This is why the long-term cumulative toxicity of ARV drugs is a major issue. Indeed as a consequence of potent ART strategies, in 2011 over 88% of patients on ART in the French Hospital database (ANRS CO4 FHDH) achieved viral suppression with HIV-RNA plasma viral load < 50 copies/mL and nearly 60% had CD4 > 500/mm3. As a consequence of massive reduction of mortality and morbidity related to HIV, infected patients are aging with 40% of patients over 50 years of age in the ANRS CO4 FHDH. The current standard-of-care for antiretroviral therapy consists in a triple drug combination with two nucleoside reverse transcriptase inhibitors (NRTIs) plus either a non-nucleoside reverse transcriptase inhibitor (NNRTI), a protease inhibitor (PI), or an integrase inhibitor (INSTI). NRTIs and PIs have been associated to cumulative long-term toxicity such as bone and renal disorders related to tenofovir and increased cardio-vascular risk with PIs. In general population, aging is associated with well-known comorbidities such as bone demineralization, increased incidence of cardio or cerebrovascular disease, diabetes, renal dysfunction. HIV infected patients are at a greater risk for such abnormalities. Another crucial concern is the high probability of drug-drug interactions in HIV-infected patients, between ART and comedications. Alternative strategies are needed, which must address the following questions: how to maintain the control of HIV viral replication while minimizing the occurrence of long-term clinical and metabolic complications, and minimizing the risk of drug-drug interactions? This study is an open label, randomized, switch study over 96 weeks in which virally suppressed patients on a stable combined ART regimen will be randomized (2:1) to an immediate switch to doravirine/raltegravir (immediate switch group) or to the maintaining of their current ART followed by a switch to doravirine/raltegravir at W48 (delayed switch group). Patients will be followed during 96 weeks.

The availability of antiretroviral therapy has led to a reduction in morbidity and mortality in patients with chronic HIV infection. The treatment, however, is not free of side effects, has potential interactions with other medications, is expensive and can be complex, especially in those patients who are very experienced and with mutations that give them resistance to multiple drugs. For this reason, the development of simplification strategies that avoid unnecessary exposure to antiretroviral agents remains of great interest. This is a simplification study, in which the investigators try to evaluate that with less medication the investigator can maintain the same virological control of the disease. This would mean a lower burden of medication for patients, facilitating its administration and reducing the number of unwanted side effects. Specifically, the investigators intend to evaluate the treatment with Darunavir / cobicistat plus Dolutegravir as a simplification strategy, since both drugs are taken once a day, have a powerful antiviral activity, even against antiretroviral resistant viruses, and are among the best tolerated (with fewer side effects). The results reported in some observational studies suggest that two-drug therapy (bitherapy) as a simplification strategy could also be safe and effective, however, as far as the investigators know, there are no data and clinical trials that specifically evaluate darunavir / cobicistat plus dolutegravir as a strategy of simplification.
