简要总结
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.
详细描述
The recent years have highlighted the cumulative toxicities of long-term exposure to antiretroviral drugs. Cardiovascular disease is one of the most common comorbidities in the aging HIV-infected population. Coronary artery disease (CAD) results from a combination of increasing age, traditional risk factor such as smoking, toxicity from long-term ART, and potentially related to HIV immune activation.
Most of boosted PIs and the NNRTI [efavirenz] are associated to an increase in triglycerides and total cholesterol plasma levels. In the ANRS CO8 APROCO COPILOTE cohort about 30% of patients developed hypertriglyceridemia. Prevalence of lipodystrophy and metabolic alterations and these alterations appear as early as 12 months after the initiation of PI therapy.
The prevalence of osteopenia and osteoporosis in HIV-infected individuals is higher in HIV-infected compared with HIV-negative individuals ranging, from 23 to 65% for osteopenia and from 3 to 22% for osteoporosis according to the studies [13-16] with, as consequence, a higher prevalence of patients with fracture (p < 0.0001).
Tenofovir is currently the most widely used antiretroviral drug. Globally, clinical trials have suggested that renal toxicity related to tenofovir is low (approximately 1%) in selected populations from clinical studies. However, observational cohort studies have suggested that this risk was higher with rates varying from approximately 2%.
In a systematic review and meta-analysis whereas over time with longer exposure to antiretroviral drugs the overall relative risk of renal disease was 3.87 (95% CI: 2.85-6.85) in HIV-infected patients compared to HIV-uninfected in ART treated patients. 0.54 (95% CI: 0.29-0.99) compared to naïve patients and 1.56 (95% CI: 0.83-2.93) in patients treated with tenofovir compared to patients without tenofovir.
