Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Approximately 11 Japanese participants will be randomized in an 8:3 ratio into 1 of the 2 single-blinded treatment arms; AZD8233 high dose or placebo. Participants will be dosed SC on Days 1, 8, 29, and 57.
Part B:This is designed as a randomized, double-blind, placebo-controlled, dose-ranging, phase 2 study. Approximately 60 Japanese participants will be randomized in a 1:1:1 ratio into 1 of the 4 double-blinded treatment arms; AZD8233 low dose, AZD8233 medium dose, or placebo. Participants will be dosed SC on Days 1, 29, and 57.
Part C:This is designed as a randomized, single-blind (blinding of participants and sites), placebo-controlled, multiple dose, phase 1 study.
Approximately 11 Japanese participants will be randomized in an 8:3 ratio into 1 of the 2 single-blinded treatment arms; AZD8233 medium dose or placebo. Participants will be dosed SC on Days 1, 29, and 57.
