Plain-language summary

The purpose of this study is to evaluate the safety, tolerability and PK profile of single and repeat ascending doses of GSK3186899 in healthy subjects. This is a Phase 1 first time in human study, to investigate the effect of food on PK of GSK3186899. This study will consists of two parts. Part A (dose escalation phase) will be a single ascending, sequential cross-over design in cohorts 1, 2 and 3 of subjects. Cohort 1 and 2 will be 4-way cross-over which includes 4 dosing regimens of GSK3186899 and placebo (3:1 ratio) under fasted conditions. Cohort 3 will be 2-way cross-over which includes 2 treatment periods, 2 dosing regimens in fasted and fed conditions. In Part B (repeat dose escalation phase) subjects will be randomized to receive repeat doses of either GSK3186899 or placebo (3:1 ratio) in either fed or fasted conditions. Part B will be conducted based on the review of all safety, tolerability and PK data from Part A. The study duration includes screening, treatment periods and follow-up.

Inclusion Criteria * Subject must be 18 to 55 years of age inclusive, at the time of signing the informed consent. * 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. A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the normal reference range for the population being studied may be included only if the Investigator in consultation with the Medical Monitor (if required) agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. * Body weight \>=50 kilogram (kg) and body mass index (BMI) within the range 18.5 to 28 kilogram per square meter (kg/m\^2) (inclusive). * Male and/or female subjects: A male subject with a female partner of reproductive potential must agree to use contraception during the treatment period and for at least 90 days after the last dose of study treatment and refrain from donating sperm during this period. A female subject is eligible to participate if she is not a woman of childbearing potential (WONCBP). * Capable of giving signed informed consent. Exclusion Criteria * History or presence of or current cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significan…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
