Brief Summary

Patients infected and living with HIV are getting older and have more and more non-HIV co-morbidities. These expose them to polypharmacy that increases the risk of pharmacological interaction. Bictegravir, co-formulated with emtricitabine (FTC) and tenofovir alafenamide (TAF) (BIKTARVY) a new generation integrase inhibitor with a high genetic barrier and had no drug interaction may be a treatment of choice for participant over 65 years old who are HIV infected . BIKTARVY improve adherence and quality of life; and on the other hand it would limit the risks of pharmacological interaction. In addition, the use of TAF reducing the risk of long-term renal toxicity and adverse effects on bone would be of interest in this aging population and more at risk of osteoporosis.

Detailed Description

HIV-1-infected patients over 65 years old at risk of polymedication HIV-1-infected adults aged ≥ 65 years who are virologically-suppressed (HIV-1 RNA \<50 copies/mL) on a regimen containing a pharmacokinetic enhancer as ritonavir or cobicistat Evaluate the antiviral efficacy of 24 weeks treatment with the fixed dose combination(FDC) of TAF/FTC/BIC

Arm && Interventions
GroupInterventionDescription
open label, multicentric, non randomizedBIKTARVY 50Mg-200Mg-25Mg Tabletone arm study to evaluate the safety and efficacy of switching from ritonavir- or cobicistat- booster containing regimens to a fixed-dose combination (FDC) of tenofovir alafenamide (TAF), emtricitabine (FTC) and bictegravir (BIC) in over 65 years old HIV-1-infected patients with virological suppression. Polymedications and drug-drug interactions will be analysed.
