HIV Infections
Conditions
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
Interventions
At BSL all the participants will be switched from a booster containing regimen (ritonavir or cobicistat) to TAF/FTC/BIC (BIKTARVY).

Eligibility
Inclusion criteria
* HIV-1-infected patient * Age \> 65 years old * Plasma HIV RNA ≤ 50 copies/mL for ≥ 6 months: one blip between 50 et 200 cp/ml is allowed in the past 6 months before screening. * Currently receiving an antiretroviral regimen containing a booster, ritonavir or cobicistat * No resistance mutation to integrase inhibitors on cumulative HIV RNA genotype. The reverse transcriptase resistant mutations M184V plus one TAM are allowed. * If no genotype is available, DNA genotype will be performed at screening visit: no resistance mutation to integrase inhibitors, the reverse transcriptase resistant mutations M184V plus one TAM are allowed. * Patient enrolled in or a beneficiary of a Social Security program (State Medical Aid or AME is not a Social Security program) * Informed consent form signed by patient and investigator
Exclusion criteria
* HIV-2 infection * Currently receiving one of the following drugs: Hypericum perforatum, rifampicin, rifabutin, carbamazepine, oxcarbazepine, phenobarbital, phenytoin, sucralfate, cyclosporine, primidone, ténofovir et adéfovir. * Hemoglobin \< 10g/dL * Platelets \< 100 000/mm3 * Hepatic transaminases AST and ALT \> 3x upper limit of normal (ULN) * Severe hepatic insufficiency (Child Pugh Class C) * Creatininemia clairance \< 30 mL/min (MDRD) * History or presence of allergy to the trial drugs or their components * Patients participating in another clinical trial including an exclusion period that is still ongoing during the screening phase * Patients under judicial protection due to temporarily and slightly diminished mental or physical faculties or under legal guardianship.
