About
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.
Full 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.

Exclusion criteria
-
History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the potential subject at risk because of participation in the study, or influence the results or the potential subject's ability to participate in the study.
-
History or presence of gastrointestinal, hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
-
Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of IMP.
-

-
Has received a new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the first administration of IMP in this study. The period of exclusion begins 3 months after the final dose or 1 month after the last visit whichever is the longest.
-
Plasma donation within 1 month of Screening or any blood donation/loss more than 500 mL during the 3 months prior to Screening. 10.

-
Use of drugs with enzyme-inducing properties such as St John's Wort within 3 weeks prior to the first administration of IMP.
-

-
Involvement of any AstraZeneca or Clinical Unit employee or their close relatives.
-
Judgment by the Investigator that the potential subject should not participate in the study if they have any ongoing or recent (i.e., during the Screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions and requirements.
-

-
History of a clinically significant non-traumatic bleed or clinically significant bleeding risk, as judged by the Investigator.
