What researchers measure

Primary outcomes

  1. Parts 1 and 2: Area Under the Concentration-time (AUC) of Brensocatib in Plasma

    Pharmacokinetics of brensocatib following a single dose in healthy participants will be assessed.

    Time frame: Pre-dose and at multiple timepoints post-dose on Days 1 to 7, 17 (Part 1), and Days 1 to 7, 12 to 18 (Part 2)

Secondary outcomes

  1. Parts 1 and 2: Number of Participants Who Experienced at Least One Adverse Event (AE)

    Safety and tolerability of brensocatib when administered alone and in combination with rifampin/esomeprazole will be determined in healthy participants.

    Time frame: Up to Day 31 (Part 1) and up to Day 26 (Part 2)
