A Comparative Study to Investigate the Difference in Blood Levels of Two Different Formulations of GSK5784283

Summary

The purpose of this study is to compare how two different formulations of the study medicine (GSK5784283) move through the body over time (pharmacokinetic \[PK\] study) in healthy adults. The aim of the study is to see how the body processes GSK5784283 and determine if the study medicine is safe, how well it is tolerated by the body and if the study medicines being tested work in the body in the same way.

Eligibility

Inclusion Criteria:

* Participants who are healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and ECG.
* Body weight greater than or equal (\>=) 50 kilogram (kg) (110 pounds \[lbs\]) and body mass index within the range 19 to 30 kilogram per meter square (kg/m\^2) (inclusive).

* Any clinically relevant abnormal findings in physical examination, hematology, clinical chemistry, urinalysis, vital signs during screening period which in the opinion of the investigator, may put the subject at risk because of his/her participation in the study, or may influence the results of the study, or the subject's ability to participate in the study.
* Live vaccine(s) within 1 month prior to screening or plans to receive such vaccines during the clinical study.
