Brief Summary

This is an open-label, single-sequence, multiple-dose, 3 cohort study to investigate the effects of DRV/RTV and/or ETR on the pharmacokinetics (PK) of GSK3640254 and the effects of GSK3640254 on the PK of DRV/RTV and/or ETR.

Eligibility Criteria

Inclusion Criteria

• Participant must be 18 to 50 years of age inclusive, at the time of signing the informed consent.
• Participants who are overtly healthy as determined by investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring (history and screening ECG).
• Body weight more than or equal to (>=)50.0 kilograms (kg) (110 pounds [lbs]) for men and >=45.0 kg (99 lbs) for women and body mass index within the range 18.5 to 31.0 kilograms per square meter (kg/m^2) (inclusive).
• Male or female participants:

1. Male participants should not engage in intercourse while confined in the study site. There is no need for an extended period of double barrier use or prolonged abstinence after study discharge.

2. Female participants:

(i) A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies: Is not a woman of childbearing potential (WOCBP) OR Is a WOCBP and using a non-hormonal contraceptive method that is highly effective, with a failure rate of less than (<)1 percent (%) for 28 days before intervention, during the intervention period, and for at least 28 days after the last dose of study intervention. The investigator should evaluate the effectiveness of the contraceptive method in relationship to the first dose of study intervention.

(ii) A WOCBP must have a negative highly sensitive serum or urine pregnancy test at screening and check-in (Day -1).

• Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the Informed consent form (ICF) and in this protocol.

Exclusion Criteria

• Participants with 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 (for example [e.g.], gastroesophageal reflux disease, gastric ulcers, gastritis) or hepatic and/or renal function that could interfere with the absorption, metabolism, and/or excretion of the study intervention or render the participant unable to take oral study intervention.
• Prior cholecystectomy surgery (prior appendectomy is acceptable).
• Clinically significant illness, including viral syndromes within 3 weeks of dosing.
• A participant with known or suspected active Coronavirus Disease-2019 (COVID-19) infection or contact with an individual with known COVID-19, within 14 days of study enrollment (World Health Organization [WHO] definitions).
• 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 (more than [>]6 months) outpatient treatment. Participants 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 Healthcare/GlaxoSmithKline (VH/GSK) 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 participant's ability to comply with the dosing schedule and protocol evaluations or which might compromise the safety of the participant.

• Unable to refrain from the use of prescription or nonprescription drugs including vitamins, herbal and dietary supplements (including Saint [St] John's wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study intervention and for the duration of the study.
• Treatment with any vaccine within 30 days prior to receiving study intervention.

• Participation in another concurrent clinical study or prior clinical study (with the exception of imaging trials) prior to the first dosing day in the current study: 30 days, 5 half-lives, or twice the duration of the biological effect of the study intervention (whichever is longer).
• Prior exposure to GSK3640254 or prior intolerance to DRV/RTV or ETR in this or another clinical study.
• Prior intolerance to any other study medications: DRV/RTV or ETR.
• Where participation in the study would result in donation of blood or blood products in excess of 500 milliliters (mL) within 56 days.
• Any positive (abnormal) response confirmed by the investigator on a screening clinician- or qualified designee-administered Columbia-Suicide Severity Rating Scale (C-SSRS).
• Systolic blood pressure <100 millimeters of mercury (mm Hg). Up to 2 repeats are allowed for confirmation.
• Any significant arrhythmia or ECG finding (e.g., prior myocardial infarction in the past 3 months, symptomatic bradycardia, non-sustained or sustained atrial arrhythmias, non-sustained or sustained ventricular tachycardia, any degree of atrioventricular block, or conduction abnormality) which, in the opinion of the investigator or VH/GSK medical monitor, will interfere with the safety for the individual participant.

1. Heart rate: <50 or >100 beats per minute (bpm).

2. PR interval >200 milliseconds (ms).

3. Corrected QT interval (QTc) >450 ms.

• History of regular alcohol consumption within 6 months of the study, defined as an average weekly intake of >14 units. One unit is equivalent to 8 grams (g) of alcohol: a half-pint (approximately 240 mL) of beer, 1 glass (125 mL) of wine, or 1 (25 mL) measure of spirits.
• Unable to refrain from tobacco or nicotine-containing products within 3 months prior to screening.
