PK Parameter: Cmax of ATV, PRA, and ROS	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	Cmax is defined as the maximum observed concentration of drug.
PK Parameter: AUCinf of ATV, PRA, and ROS	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	AUCinf is defined as the concentration of drug extrapolated to infinite time.

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants Experiencing Treatment Emergent Adverse Events (TEAEs)	Sequence AB: First dose up to 47 days, Sequence BA: First dose up to 50 days	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.
Percentage of Participants With Severity Grade 3 or Above Treatment-Emergent Laboratory Abnormalities	Sequence AB: First dose up to 47 days, Sequence BA: First dose up to 50 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.
