This study will evaluate the relative bioavailability of the B/F/TAF tablet for oral suspension formulation compared to the adult-strength B/F/TAF tablet and will inform on appropriateness of this formulation for future clinical studies in children with HIV.

Have a calculated body mass index (BMI) of = 19.0 and = 30.0 kg/m2 at screening 5. Have a creatinine clearance (CLcr) = 90 mL/min (using the Cockcroft-Gault method {Cockcroft 1976}) based on serum creatinine and actual body weight as measured at screening 6. Females of childbearing potential must have a negative serum pregnancy test at screening and clinic admission (unless permanently sterile or greater than 2 years postmenopausal) 7. Male subjects and female subjects of childbearing potential who engage in heterosexual intercourse must agree to use protocol specified method(s) of contraception. 8. Subjects must refrain from sperm and egg donation from clinic admission (eg, Day -1), throughout the study period, and continuing for at least 7 days following the last dose of study drug. 9. Subjects have not donated blood within 56 days of study entry or plasma within 7 days of study entry and must refrain from blood donation from clinic admission, throughout the study period, and Continuing for at least 30 days following the last dose of study drug. 10. Screening laboratory and 12-lead ECG evaluations must be without clinically significant abnormalities as assessed by the investigator 11. Have liver disease or liver function tests such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, and total bilirubin equal to or below the upper limit of normal at screening 12. Must be willing and able to comply with all study requirements 13.

Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 198 F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range

Exclusion criteria

Exclusion criteria: 1. Be a lactating female 2. Have received any study drug within 30 days prior to study dosing 3. Have current alcohol or substance abuse judged by the investigator to potentially interfere with subject compliance or subject safety 4. Have a positive test result for human immunodeficiency virus type 1 (HIV-1) antibody, hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibody 5. Have poor venous access that limits phlebotomy 6. Have taken any prescription medications or over-the-counter medications, including herbal products, within 28 days prior to start of study drug dosing, with the exception of vitamins and/or acetaminophen and/or ibuprofen and/or hormonal contraceptive medications 7.

Design outcomes

Primary

MeasureTime frame
Primary end point(s): The primary endpoints are the PK parameters AUClast, AUCinf, and Cmax of BIC, FTC, and TAF in Cohorts 1 and 3, as applicable.;Timepoint(s) of evaluation of this end point: (Days 1, 10, and 19): predose (= 5 min), 5 min, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 5, 6, 8, 12, 24, 36, 48, 72, 96 and 120 hours postdose.;Main Objective: - To evaluate the relative bioavailability of a B/F/TAF FDC pediatric tablet for oral suspension formulation relative to the adult B/F/TAF FDC tablet formulation - To evaluate the bioequivalence of a F/TAF FDC pediatric tablet for oral suspension formulation relative to the B/F/TAF FDC pediatric tablet for oral suspension formulation;Secondary Objective: - To evaluate the effect of concomitant food intake on the PK of a B/F/TAF FDC pediatric tablet for oral suspension formulation - To evaluate the safety and tolerability of single doses of B/F/TAF and F/TAF FDC pediatric tablet for oral suspension formulations in healthy subjects
