The study will test an experimental drug called B/F/TAF (bictegravir/emtricitabine/tenofovir alafenamide) fixed-dose combination (FDC) for the treatment of HIV-1 infection. The purpose of this study is to evaluate the effectiveness of switching to B/F/TAF FDC in HIV-1 infected adults aged = 65 years who are virologically suppressed (HIV-1 RNA test <50 copies/mL) currently on elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide FDC or tenofovir disoproxil fumarate containing regimens.

A Phase 3b, Multicenter, Open-Label Study to Evaluate Switching from an Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide Fixed-Dose Combination Regimen or a Tenofovir Disoproxil Fumarate Containing Regimen to Fixed-Dose Combination of Bictegravir/Emtricitabine/Tenofovir Alafenamide in Elderly, Virologically-Suppressed, HIV-1 Infected Subjects Aged = 65 Years

Inclusion criteria

Inclusion criteria: Subjects must meet all of the following inclusion criteria to be eligible for participation in this study. 1) The ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures 2) Age = 65 years 3) Currently receiving an ARV regimen of E/C/F/TAF FDC (or FTC/TDF + 3rd agent if currently or previously participated in GS-US-292-1826) for = 3 months 4) Documented plasma HIV-1 RNA 1 year 12) Hepatic transaminases (AST and ALT) = 5 upper limit of normal (ULN) 13) Total bilirubin = 1.5X ULN or normal direct bilirubin 14) Adequate hematologic function (absolute neutrophil count = 750/mm3 (= 0.75 GI/L); platelets = 50,000/mm3 (= 50 GI/L); hemoglobin = 8.5 g/dL (= 85 g/L)) Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) no F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 80

Exclusion criteria

Exclusion criteria: Subjects who meet any of the following exclusion criteria are not to be enrolled in this study. 1) An opportunistic illness indicative of stage 3 HIV diagnosed within the 30 days prior to screening 2) Subjects experiencing decompensated cirrhosis (eg, ascites, encephalopathy, or variceal bleeding) 3) Have been treated with immunosuppressant therapies or chemotherapeutic agents within 3 months of study screening, or expected to receive these agents or systemic steroids (e.g. prednisone doses > 10 mg daily or equivalent) during the study (eg, corticosteroids, immunoglobulins, and other immune- or cytokine-based therapies) 4) Current alcohol or substance use judged by the Investigator to potentially interfere with subject study compliance 5) Malignancy within 5 years of screening other than cutaneous Kaposi’s sarcoma, completely resected non-melanoma skin cancer (basal cell carcinoma or non-invasive cutaneous squamous carcinoma), or completely resected carcinoma in-situ of the cervix (CIN 3) or anus (AIN 3). A prior malignancy treated with curative therapy and for which there has been no evidence of disease for at least five years prior to screening is allowed. 6) Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to Day 1 7) Participation in any other clinical trial, including observational studies, without prior approval from the Medical Monitor 8) Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the subject unsuitable for the study or unable to comply with the dosing requirements 9) Known hypersensitivity to B/F/TAF FDC tablets, their metabolites, or formulation excipient 10) Subjects receiving ongoing therapy with any of the medications listed in the protocol, including drugs not to be used with BIC, FTC, and TAF 11) Acute hepatitis in the 30 days prior to study entry 12) Active tuberculosis infection
