Summary

This is a phase 2b, randomized, multicenter, parallel group, partially blind (to GSK3640254 doses [100, 150 and 200 milligrams {mg}]), active controlled clinical trial. It will aim to investigate the safety, efficacy and dose-response of GSK3640254 compared to dolutegravir (DTG), each given in combination with 2 Nucleoside Reverse Transcriptase Inhibitors (NRTIs) (abacavir/lamivudine [ABC/3TC] or emtricitabine/tenofovir alafenamide [FTC/TAF])

History of ongoing or clinically relevant hepatitis within the previous 6 months
History of drug or other allergy that, in the opinion of the Investigator or Medical Monitor, contraindicates their participation

Any pre-existing physical or other psychiatric condition (including alcohol or drug abuse), which, in the opinion of the Investigator or ViiV Medical Monitor (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
A pre-existing condition, in the opinion of the Investigator or ViiV Medical Monitor, that could interfere with normal gastrointestinal anatomy or motility (e.g., gastroesophageal reflux disease [GERD], gastric ulcers, gastritis, inflammatory bowel disease), hepatic and/or renal function, or with the absorption, metabolism, and/or excretion of the study drugs or render the participant unable to take oral study treatment
Myocardial infarction in the past 3 months
