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.

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.

| Part C:Absolute change from baseline in log-transformed PCSK9 in plasma and Percent change from baseline in PCSK9 in plasma. | To assess the effect of AZD8233 on levels of PCSK9 following SC administration of multiple doses. | At screening, Day -1, Days 1 to 3 and Days 57 to 58 (pre-dose and 48 hours post-dose), Day 8, Days 15, 22, Day 29 (pre-dose), Days 36, 44, Day 56, week 2 to 14 (at 2, 4, 6, 8, 10, 12, and 14 weeks) and week 16 post-dose. | 
| Part C:Percentage change from baseline in levels of LDL-C in serum. | To assess the effect of AZD8233 on levels of LDL-C following SC administration of multiple doses. | At screening, Day -1, Days 1 to 3 and Days 57 to 58 (pre-dose and 48 hours post-dose), Day 8, Days 15, 22, Day 29 (pre-dose), Days 36, 44, Day 56, week 2 to 14 (at 2, 4, 6, 8, 10, 12, and 14 weeks) and week 16 post-dose. | 
| Part C:Levels of other lipid parameters of TC, HDL-C, Non-HDL-C, VLDL-C, ApoA1, ApoB, Lp(a) , Triglycerides. | To assess the effect of AZD8233 on other lipid parameters versus placebo. | Measurement at screening, Day -1, Days 1 to 3 and Days 57 to 58 (pre-dose and 48 hours post-dose), Day 8, Days 15, 22, Day 29 (pre-dose), Days 36, 44, Day 56, week 2 to 14 (at 2, 4, 6, 8, 10, 12, and 14 weeks) and week 16 post-dose. |
