A Single and Multiple Ascending Dose Study to Investigate Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AZD2389 in Healthy Participants

A Phase I, Randomized, Single-blind, Placebo-controlled Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AZD2389 After Single and Multiple Ascending Doses to Healthy Participants.

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.

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.

Each participant in Part A and Part B will be involved in the study for up to 8 weeks.

Inclusion Criteria:

• Healthy male and female (of non-childbearing potential) participants with suitable veins for cannulation or repeated venipuncture.
• For the healthy Japanese cohorts (Parts A2 and B2): healthy participants are to be Japanese (e.g., natives of Japan or Japanese Americans), defined as having both parents and 4 grandparents who are Japanese. This includes healthy second and third generation participants of Japanese descent whose parents or grandparents are living in a country other than Japan.
