Brief summary
A Phase 1 and 2 Study of AZD8233 in Participants with Dyslipidemia and this study consists of Part A , Part B and Part C. Part A is designed as a randomized, single-blind (blinding of participants and sites), placebo-controlled, multiple dose, phase 1 study. Part B is designed as a randomized, double-blind, placebo-controlled, dose-ranging, phase 2 study. Part C is designed as a randomized , single-blind (blinding of participants and sites), placebo-controlled, multiple dose, phase 1 study.
Detailed description
Part A: 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 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.

| Part B: Change in LDL-C in Serum at Week 12 | Baseline to week 12 | Part B: Change from baseline in LDL-C at week 12. Results are based on Mixed Model Repeated Measures (MMRM) analysis on the log-transformed change from baseline. Log-transformed change from baseline is calculated as the visit value in log minus the baseline value in log. The results from the model are then back transformed. Note: log(week 12 data) - log(baseline data) = log(week12/baseline), which is a ratio |
