The primary objective of this study is to evaluate the effect of filgotinib on a mixed organic anion transporting polypeptide/cytochrome P450 3A (OATP/CYP3A), OATP/ breast cancer resistance protein (BCRP), and OATP substrates using phenotypic probes.

Pharmacokinetic (PK) Parameter: AUClast of ATV, PRA, and ROS
AUClast is defined as the concentration of drug from time zero to the last observable concentration.
Time frame: AB (Days 1,3,12,14) and BA (Days 6,8,18,20): Predose, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 48 postdose; AB (Days 1,12) and BA (Days 6,18): 5,10,36 hours post dose; AB (Days 3,14) and BA (Days 8,20): 72 hours postdose
PK Parameter: AUCinf of ATV, PRA, and ROS
AUCinf is defined as the concentration of drug extrapolated to infinite time.
Time frame: AB (Days 1,3,12,14) and BA (Days 6,8,18,20): Predose, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 48 postdose; AB (Days 1,12) and BA (Days 6,18): 5,10,36 hours post dose; AB (Days 3,14) and BA (Days 8,20): 72 hours postdose
PK Parameter: Cmax of ATV, PRA, and ROS
Cmax is defined as the maximum observed concentration of drug.
Time frame: AB (Days 1,3,12,14) and BA (Days 6,8,18,20): Predose, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 16, 24, 48 postdose; AB (Days 1,12) and BA (Days 6,18): 5,10,36 hours post dose; AB (Days 3,14) and BA (Days 8,20): 72 hours postdose
Percentage of Participants Experiencing Treatment Emergent Adverse Events (TEAEs)
An adverse event (AE) was any untoward medical occurrence in a participant administered a study drug, which did not necessarily have a causal relationship with the treatment. AE was therefore any unfavorable and/or unintended sign, symptom, or disease temporally associated with the use of the study drug, whether or not considered related to the study drug. TEAEs: AE with an onset date on or after the study drug start date and no later than 30 days after study drug stop date; or any AE leading to study drug discontinuation.
Time frame: Sequence AB: First dose up to 47 days, Sequence BA: First dose up to 50 days
Percentage of Participants With Severity Grade 3 or Above Treatment-Emergent Laboratory Abnormalities

Administered as tablet orally once daily for 11 days.
Treatment-emergent laboratory abnormalities were graded using Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 of Adverse Events and Laboratory abnormalities. Laboratory abnormalities were graded as Grade 1 (mild), Grade 2 (moderate), Grade 3 (severe), Grade 4 (Life-threatening), Grade 5 (Death). Percentage of participants with Grade 3 or higher treatment-emergent laboratory abnormalities were reported.
Time frame: Sequence AB: First dose up to 47 days, Sequence BA: First dose up to 50 days
