a study to assess the drug absorption into the blood after administration of 3 doses of azd5718

Conditions: Coronary Artery Disease

Summary: this study will be conducted to evaluate the azd5718 pharmacokinetic (pk) doses in order to determine exposure in a new dose range and compare with previous results. this study will include 14 subjects in a single site in united kingdom. each subject will be involved in the study for 6 to 7 weeks.

this study will be an open-label, randomized, 3-period, 3-treatment, crossover study performed in healthy subjects at a single study center. a total of 14 healthy male and female subjects (of no childbearing potential) will be randomized to ensure that at least 12 subjects are evaluable. each subject will receive 3 different treatments at least 4 days apart and will be dosed following an overnight fast of at least 10 hours. the following treatments will be given: * treatment a: azd5718 dose a tablet * treatment b: azd5718 dose b tablet * treatment c: azd5718 dose c tablet the study will comprise: * a screening period of maximum 28 days. * three treatment periods during which subjects will be resident from the day before first dosing with azd5718 (day -1) in treatment period 1 until at least 48 hours after last dosing with azd5718 in treatment period 3 for collection of pk and safety samples. subjects will be discharged on day 3 of treatment period 3. * a follow up visit, 5 to 7 days after the last dose of investigational medicinal product (imp). there will be a minimum washout period of 4 days between each dose administration. each subject will be involved in the study for 6 to 7 weeks. this study will be conducted in male and female subjects aged 18 to 55 years.
