Brief summary
The purpose of this study is to assess the safety, tolerability, and pharmacokinetics (PK) of AZD8965 via single and multiple ascending doses in healthy participants (including Japanese and Chinese participants), and to assess the effect of food on the safety, tolerability, and PK of orally administered AZD8965.
Detailed description
This is a first in human single and multiple ascending dose study. The study consists of 4 parts: Part 1 (single ascending dose \[SAD\]), Part 2 (multiple ascending dose \[MAD\]), Part 3A (Japanese and Chinese SAD), Part 3B (Japanese and Chinese combined SAD and MAD), and Part 4 (Food Effect). Each study part includes a 28-day screening period and a residential period during which participants will be resident at the Clinical Unit from the day before study intervention administration (Day -1) until at least 48-72 hours after the study intervention administration.
