- Brief Summary
Human immunodeficiency virus (HIV) infection frequently involves combination drug therapy for its treatment; hence, it is important to understand their interactions and resulting changes in exposure which are associated with medications. This is a Phase-1, open-label, fixed-sequence 2-period, one-way drug interaction study to assess the pharmacokinetic (PK), safety, and tolerability of GSK3640254 and Tenofovir alafenamide/emtricitabine (TAF/FTC) when administered alone and in combination in healthy subjects. The study will consist of a screening period of 28 days before the first dose of study intervention followed by 2 sequential treatment periods. Subjects will be administered TAF/FTC 25/200 milligram (mg) once daily (QD) on Days 1 to 14 of Period 1 followed by co-administration of TAF/FTC 25/200 mg QD with GSK3640254 200 mg QD on Days 1 to 7 of Period 2.

- Subject must be 18 to 55 years of age inclusive, at the time of signing the informed consent.
- Subjects who are healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring (history and ECG).
- Body weight >=50.0 kilograms (kg) (110 pound [lbs]) for men and >=45.0 kilograms [kg] (99 lbs) for women and body mass index (BMI) within the range 18.5 to 31.0 kilograms per meter square (kg/m^2) (inclusive).
- Male or female; A female subject is eligible to participate if she is not pregnant, not breastfeeding and not a woman of childbearing potential (WOCBP).
- Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and protocol.
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
- A pre-existing condition interfering with normal gastrointestinal (GI) anatomy or motility (e.g.,gastroesophageal reflux disease, gastric ulcers, gastritis), hepatic and/or renal function, that could interfere with the absorption, metabolism and/or excretion of the study drugs or render the subject unable to take oral study intervention.
- Any history of significant underlying psychiatric disorder including, but not limited to, schizophrenia, bipolar disorder with or without psychotic symptoms, other psychotic disorders, or schizotypal (personality) disorder.
- Any history of major depressive disorder with or without suicidal features or anxiety disorders, that required medical intervention (pharmacologic or not) such as hospitalization or other inpatient treatment and/or chronic (>6 months) outpatient treatment. Subjects with other conditions such as adjustment disorder or dysthymia that have required shorter term medical therapy (<6 months) without inpatient treatment and are currently well-controlled clinically or resolved may be considered for entry after discussion and agreement with the ViiV Medical Monitor.
- Any pre-existing physical or other psychiatric condition (including alcohol or drug abuse), which, in the opinion of the investigator (with or without psychiatric evaluation), could interfere with the subject's ability to comply with the dosing schedule and protocol evaluations or which might compromise the safety of the subject.
- Medical history of cardiac arrhythmias or cardiac disease or a family or personal history of long QT syndrome.
- History of any kidney disease or current or chronic history of impaired renal function as indicated by an estimated creatinine clearance <80 milliliters per minute (mL/min). Creatinine clearance (CrCL) is estimated by either of the following methods: (a) The Modification of Diet in Renal Disease (MDRD) equation: estimated glomerular filtration rate (eGFR) (milliliter [mL]/minute [min]/1.73 meter square [m^2]) = 175 x (SCr)^-1.154 x (Age)^-0.203 x 0.742 [if female] x 1.212 [if African American] glomerular filtration rate (GFR) is expressed in mL/min/1.73 m^2, SCr is serum creatinine expressed in milligrams per deciliter (mg/dL), and age is expressed in years. (b)The Cockcroft-Gault equation: CrCL(mL/min) ={((l40-age) x weight)/(72xSCr)}x 0.85 (if female) CrCL is expressed in mL/min, age is expressed in years, weight is expressed in kg, and SCr is serum creatinine expressed in mg/dL.
