Trial overview
Official title: An Open-Label, Single Dose Study to Compare Ambrisentan (GSK1325760) Concentrations Determined Using Venous Blood Sampling and Capillary Micro Sampling Methods in Healthy Adult Participants
Trial description: This is an open-label, single dose, single centre study in healthy adult participants to compare ambrisentan (GSK1325760) concentrations determined using capillary micro sampling and venous blood sampling methods. Parallel PK samples will be collected at the same sampling time point from the same subject for the comparison of the two methods. Specifically, sampling methods for comparison are (i) the venous sample collection used in all historic studies with ambrisentan versus (ii) capillary micro sampling collection using the Tasso M20 device.

Be abstinent from heterosexual intercourse as their preferred and usual lifestyle and Must agree to use contraception/barrier.
- Female participant of non-childbearing potential (WONCBP)

- Alanine transaminase (ALT) >1.5x upper limit of normal (ULN)
- Aspartate transaminase (AST) >1.5x upper limit of normal (ULN)
- Total bilirubin >1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35 percent (%)
