Clinical Trial Summary

Part A of this study is a Phase 1, First-in-human (FiH), randomized, single-blind, placebo controlled study to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of AZD3366 following single intravenous (IV) ascending doses. Part B of this study is a randomized, single-blind, parallel group placebo-controlled study to assess the safety, tolerability and PD of a single IV administration of AZD3366 with concomitant loading doses followed by repeated maintenance dosing of ticagrelor and acetylsalicylic acid (ASA).


Description:

The study will provide data on safety, tolerability, PK, and PD of AZD3366 in healthy subjects. Three populations (healthy subjects, healthy Japanese subjects and healthy Chinese subjects) will be enrolled into this study. This study will be conducted at a single study center in United States of America (USA). Part A of the study will investigate the safety, tolerability, PK, and PD (inhibition of platelet aggregation and capillary bleeding time [CBT]) of an IV administration of single ascending doses (SAD) of AZD3366 in healthy subjects, healthy Japanese subjects and healthy Chinese subjects. Part B of the study will investigate the safety, tolerability, and PD (inhibition of platelet aggregation and CBT) of a single IV dose of AZD3366 or placebo with concomitant administration of ticagrelor and ASA by a parallel group cohort consisting of of healthy subjects. Furthermore, the potential effect of AZD3366 on the PK of ticagrelor will be investigated. Co-medication with ASA and ticagrelor is chosen based on the Standard of Care anti-platelet treatment regimen in patients with myocardial infarction.
