A Study to Investigate the Safety and Pharmacokinetics of AZD6793 in Healthy Japanese and Chinese Participants

AstraZeneca39 enrolled

Overview

The main purpose of this study is to assess the safety, tolerability and pharmacokinetics (PK) of oral AZD6793 in healthy Japanese and Chinese participants.

This study will be conducted to assess the safety, tolerability, and PK of oral AZD6793 suspension following single (Part 1) and multiple (Part 2) administrations in healthy Japanese and Chinese participants performed at a single Clinical Unit. Part 1 of the study will comprise: * A Screening Period of maximum 28 days (Day -29 to Day -2). * A Treatment Period during which participants will be resident at the Clinical Unit from Day -1 until at least 72 hours after study intervention administration. * A Follow-up Visit within 6 ± 1 days after the study intervention administration. Part 2 of the study will comprise: * A Screening Period of maximum 28 days (Day -29 to Day -2). * A Treatment Period during which participants will be resident at the Clinical Unit from Day -1 (the day before first study intervention administration \[Day 1\]) until Day 10. * A Follow-up Visit within 6 ± 1 days after the last study intervention administration. Participants will be randomized to receive AZD6793 and placebo in both Part 1 and Part 2. Participants who enrolled in Part 1 will be excluded from participation in Part 2 of the study.
