Clinical Trial Summary

To evaluate the relative bioavailability of ticagrelor for the different formulations. A randomized cross-over design has been chosen to minimize the effects of between-subject variability and any period effects on the overall results.

Description:

This study will be an open-label, randomized, 4-period, 4-treatment, cross-over, single-center, single-dose study to assess the relative bioavailability of different formulations of ticagrelor in approximately 44 healthy adult subjects. Eligible subjects will be healthy male and female aged 18 to 55 years, with a body weight of 55 to 100 kg and a body mass index (BMI) of 18 to 30 kg/m2. Of the 44 randomized subjects, at least 36 evaluable subjects should be at the end of the last treatment period. Subjects will be randomized to 1 of 4 treatment sequences and will receive single oral doses of 4 different formulations of ticagrelor under fasted conditions. Subjects will fast for at least 10 hours prior to administration of Investigational Medicinal Products (IMPs). No fluids will be allowed apart from water which can be given until 1 hour prior to administration of the IMP and then from 2 hours after administration of the IMP. A meal can be given 4 hours after administration of the IMP.
