GroupInterventionDescription
Brensocatib + ClarithromycinBrensocatibParticipants will receive a single oral dose of brensocatib in the morning on Days 1 and 13 after an overnight fast, and oral doses of clarithromycin, twice daily (BID), with food on Days 8 to 19. On Day 13, brensocatib will be coadministered with the morning dose of clarithromycin. Clarithromycin can be taken with food, with the exception of the morning dose on the day of coadministration with brensocatib (Day 13), which will be taken after an overnight fast.

Primary Outcome Measures
NameTimeMethod
Area Under the Plasma Concentration-time Curve (AUC) of BrensocatibPre-dose and at multiple timepoints post-dose on Days 1 to 8, and Days 13 to 20

The effect of clarithromycin on the single dose pharmacokinetics of brensocatib will be assessed in healthy participants.

Secondary Outcome Measures
NameTimeMethod
Number of Participants who Experienced at Least one Adverse Event (AE)Up to Day 27

Determination of the safety and tolerability of a single oral dose of brensocatib when administered alone and with clarithromycin in healthy participants.
