A Study to Investigate Effect of Clarithromycin, a Strong CYP3A4 Inhibitor, on Brensocatib Pharmacokinetics in Healthy Participants

A Phase 1, Open-label, Fixed-sequence Study to Investigate the Effect of Clarithromycin, a Strong CYP3A4 Inhibitor, on Brensocatib Pharmacokinetics in Healthy Subjects

The primary purpose of this study is to determine the effect of clarithromycin on the single-dose pharmacokinetics (PK) of brensocatib in healthy participants.
