Kenya study tests simpler HIV drug switch for seniors

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Able and willing to understand and comply with the protocol requirements, instructions and restrictions * Able and willing to give informed consent * Have been randomised to the B/F/TAF arm and completed the B/F/TAF-elderly study. Participants should be on B/F/TAF until day 1 of entry into the current study * HIV-1 RNA viral load \< 50 copies/ml at screening (within 28 days prior to enrollment) Exclusion Criteria: * Confirmed treatment failure as defined by two consecutive HIV-1 RNA viral loads ≥ 50 copies/ml separated by at least 2 weeks, after at least 6 months on ART or after a documented HIV-1 RNA viral load \< 50 copies/ml * Using any protocol-defined prohibited medicine where the participant is unwilling or unable to switch to an alternative (see Section 5.2. under Prohibited medications and non-drug therapies) * Evidence of hepatitis B virus (HBV) infection based on the results of testing at screening for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), hepatitis B surface antibody (anti-HBs) and HBV DNA as follows: 1. Participants positive for HBsAg are excluded; 2. Participants negative for anti-HBs but positive for anti-HBc (negative HBsAg status), whether negative or positive for HBV DNA, are excluded; 3. Participants positive for anti-HBc (negative HBsAg status) and positive for anti-HBs (past and/or current evidence) are immune to HBV and are not excluded. * Has AST and/or ALT at least 5-times greater than the upper limit of normal * Severe hepatic impairment (Class C) as determined by Child-Pugh classification * Has an estimated creatinine clearance (CrCl) below 30 ml/min (as estimated using the Cockcroft-Gault estimate for glomerular filtration rate) * Documented opportunistic infection within 4 weeks prior to the study enrolment * Any condition (including illicit drug use or alcohol abuse) or laboratory results which, in the investigator's opinion, interfere with assessments or completion of the study * Untreated syphilis infection (positive rapid plasma reagin \[RPR\] at Screening without clear documentation of treatment). Participants who are at least 7 days post completed treatment are eligible. * History or presence of allergy or intolerance to the study treatment or their components or drugs of their class or a history of drug or other allergy that, in the opinion of the investigator or Medical Monitor, contraindicates their participation. * Ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma, or cervical, anal or penile intraepithelial neoplasia. * Participants who in the investigator's judgment, poses a significant suicidality risk. Participant's history of suicidal behavior and/or suicidal ideation should be considered when evaluating for suicide risk * Any evidence of any major 3TC resistance associated mutations (M184V/I and/or K65R and/or MDR) or presence of any major INSTI resistance associated mutation
