Details and patient eligibility

About

This trial is a randomized, actively-controlled, open-label, 2-way crossover bioequivalence study to determine PK parameters following treatment with test aspirin product (PL-ASA capsules) and reference aspirin product (IR-ASA tablets) administered at a single dose of 325 mg.

Full description

Healthy volunteers will be asked to sign informed consent prior to conduct any protocol specified activities at screening. A total of 20 eligible subjects will be randomized, in a fasted state, to 1 of 2 sequences of study drug administration (each study drug dose contains 325 mg aspirin) at 1:1 ratio:

  • PL-ASA capsule, IR-ASA tablet
  • IR-ASA tablet, PL-ASA capsule

After completion of the first treatment on Day 1 and following the 24 hours of sample collection, a minimum of a 7-day washout period will be required before all subjects are crossed over and receive treatment with the alternative compound; i.e., subject randomized to receive PL-ASA capsule as a first treatment will receive IR-ASA tablet as the second treatment, and vice-versa.
