Brief Summary

This study will assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of AZD2389 following single and multiple dose administration (SAD/MAD) to healthy participants.

Detailed Description

This is a Phase I, First In Human (FIH), randomized, single-blind, placebo-controlled, single and multiple ascending dose study in healthy male and/or female participants of non-childbearing potential including healthy participants of Chinese and Japanese ethnicity performed at a single center.

The study consists of 2 parts: Part A and Part B. Part A has been planned to be conducted with 78 participants and Part B has been planned to be conducted with 32 participants.
