The HIV-infected population is aging due to the success of combination antiretroviral therapy, which prolongs survival, as well as the growing number of newly diagnosed cases in adults 50 years old and over. This real-life, observational and retrospective study aims to evaluate the virological efficacy, toxicity and tolerability of Doravirine-based regimens in aged HIV-1 positive patients (> 50 years), focusing on metabolic patterns and inflammation markers.


HIV-infected individuals suffer from an accelerated aging due to the persistent and chronic activation of the immune system that leads to immune exhaustion and accelerated immunosenescence. The success of combination antiretroviral therapy, which also prolongs patients' survival, have relatively higher retention rates among HIV infected elderly patients, but only a small percentage are virally suppressed, largely due to elderly drugs interacts with ART and several comorbidities that reduces the life span of elderly people.

In this context, Doravirine is the only NNRTI with a low propensity for resistance, excellent tolerability, a superior neuropsychiatric profile compared with EFV, a superior lipid profile compared with ritonavir-boosted darunavir and EFV, minimal risk for drug- drug interactions, and no food restrictions. In addition, doravirine has a large therapeutic index and robust efficacy in patients with high viral load. However, to date, data on doravirine in HIV aged patients are still lacking.

This observational retrospective cohort in real world will aim to describe the effect of doravirine regimens, both as single drug and as fixed combination with lamivudine and tenofovir disoproxil fumarate, in aged HIV patients.

  • The primary endpoint will be the evaluation of virological efficacy defined as the proportion of patients with HIV RNA < 50 copies/mL at the end of the 48-week follow-up.
  • The secondary endpoints will be the following:
  • Change in CD4+, CD8 cell counts, CD4/ CD8 ratio from baseline to 48 weeks
  • Proportion of patients with any adverse events (AE), serious adverse events (SAE), also according to their severity.
  • Changes in total HDL and LDL-cholesterol, triglycerides, creatinine, eGFR, phosphate, AST, ALT, FIB-4, ALP, glucose, proteinuria from baseline to 48 weeks.
  • Changes of infiammatory biomarkers: D-Dimer, hsCRP and IL-6 during 48 weeks
  • Occurrence of genotypic mutations (genotypic test) in plasma samples from patients with virological failure

Clinical data will be collected from medical records and laboratory analyses comprising CD4+ T cell count, plasma HIV-1 RNA, blood cells, and plasma chemistry profiles, including fasting lipids (total cholesterol, high-density lipoprotein cholesterol [HDL], low- density lipoprotein [LDL] cholesterol, triglycerides) will be recorded.

The Time horizon for patient follow-up for outcome is at least 12 months (Baseline, 12, 24, 36, 48 weeks).
