About this trial

This is an interventional treatment trial for Dyslipidaemia focused on measuring Dose Range Finding, AZD8233, Efficacy, PK, PD, Immunogenicity, Safety, Tolerability

Eligibility Criteria

18 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Key Inclusion Criteria:

  • Male or female.
  • Participant must be 18 to 75 years of age.

Outcomes

Primary Outcome Measures

Change in Low-density Lipoprotein Cholesterol (LDL-C) at Week 12.
Change from baseline in low-density lipoprotein cholesterol (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.

Secondary Outcome Measures

Relative Change From Baseline in PCSK9 Concentration in Plasma at Week 12.
Relative change from baseline in PCSK9 concentration in plasma at week 12.
Percentage Change From Baseline in Concentration of TC, HDL-C, Non-HDL-C, VLDL-C, ApoA1, ApoB, Lp(a), Triglycerides, Remnants Cholesterol
Percentage change from baseline in concentration of TC, HDL-C, Non-HDL-C, VLDL-C, ApoA1, ApoB, Lp(a), Triglycerides, Remnants cholesterol at week 12

5. Study Description

Brief Summary
AZD8233 is a PCSK9-targeted ASO for the reduction of circulating levels of LDL-C. This study aims to evaluate the dose-dependent reduction in LDL-C after SC administration of multiple doses of AZD8233 as well as the associated adverse effects profile. The data generated will be used to guide choice of doses, dosing regimens, and sample sizes, as well as safety and PD monitoring in the further clinical development program.
Detailed Description
This is a randomized parallel, double-blind, placebo-controlled, dose-ranging Phase 2b study in approximately 108 participants with dyslipidemia. The primary objective of the study is to investigate the effect of AZD8233 on LDL-C across different dose levels. The study will be conducted at up to 25 sites in up to 4 countries. The screening period starts up to 42 days before the randomization visit and ends on Day -1. Eligible participants will attend 7 visits during the treatment period and 7 additional visits during the safety follow up period. Eligible participants are randomized across four different treatment arms in a 1:1:1:1 ratio for a 12-week treatment period. The planned treatment arms are AZD8233 low dose, AZD8233 medium dose, AZD8233 high dose, and Placebo. Participants will be dosed SC on Days 1, 8, 29, and 57.
