• 1 other identifier: BORA-1A-C301
• Study Type: interventional
• Target: 86

Brief Summary

The goal of this clinical trial is to compare the pharmacodynamics (PD), pharmacokinetics (PK), safety, and tolerability of acetylsalicylic acid powder for oral inhalation (i-ASA) with non-enteric-coated chewable aspirin (C-ASA) in healthy adults by demonstrating bioequivalence. In the first treatment period, subjects will be randomized to receive either a single dose (100 mg) of I-ASA powder via a Dry Powder Inhaler (DPI) OR a single dose (162 mg) of C-ASA tablets. After a washout period, subjects will be crossed over to receive the other treatment in the second treatment period. All subjects will receive both treatments during the study. Each single dose treatment will be followed by up to 24 hours of serial post-dose PK, PD, and safety/tolerability assessments.
