Is this trial a fit for you?

Likely a good fit

Healthy adults, generally well with BMI 18.0–32.0 kg/m2, weight ≥50 kg (males) or ≥45 kg (females), and non-childbearing potential.

Probably not a fit

Healthy volunteers who do not meet the inclusion criteria or who have recently active infections or other unstable conditions may not benefit.

What this trial studies

This Phase 1 interventional study compares two formulations of the investigational drug GSK3862995B in healthy volunteers. It aims to characterize pharmacokinetics—how the body absorbs, distributes, metabolizes, and excretes the drug—while monitoring safety and tolerability. Eligible participants are generally healthy adults meeting specific weight, BMI, and non-childbearing status criteria. The study is sponsored by GlaxoSmithKline and conducted at a dedicated GSK investigational site in Cambridge.

Why it matters

Potential benefit: Participants may not directly benefit from this study, but data could support future development of GSK3862995B.

How similar studies have gone: Phase 1 pharmacokinetic studies of similar compounds have helped establish safe dosing ranges in healthy volunteers.

* Breast cancer within the past 10 years
* Alanine transaminase (ALT) greater than (\>)1.0x upper limit of normal (ULN)
* Total bilirubin \>1.5 x ULN; Participants with Gilbert's syndrome can be included with total bilirubin \>1.5 x ULN as long as direct bilirubin is less than or equal to (\<=) 1.5 x ULN
* Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)

  * A clinically significant abnormality in the average of triplicate 12-lead ECG readings performed at screening
