A Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of AZD0780 in Participants With Dyslipidaemia

A Randomised, Double-blind, Placebo-controlled, Multi-centre, Sequential Phase II, and Phase III Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of AZD0780 Administered for up to 52 Weeks in Participants With Dyslipidaemia (AZURE-CHINA)

This is a randomised, double-blind, placebo-controlled, multi-centre, sequential Phase II and Phase III study that will evaluate the efficacy, safety, and PK of AZD0780 administered orally for up to 52 weeks in participants with elevated LDL-C. The study consist of 2 separate parts (Part A and Part B) approximately 60 participants will be randomised in Part A. There will be 2 cohorts in Part B (approximately 220 participants in Cohort 1 and 100 participants in Cohort 2).

Study Overview

• Status: Active, not recruiting
• Conditions: Dyslipidaemia
• Intervention / Treatment: Drug: Rosuvastatin Dose 1; Drug: AZD0780; Drug: Placebo; Drug: Rosuvastatin dose 2

Detailed Description

The planned study includes 2 parts. Part A will be the Phase II study and aims to evaluate the PK, PD, safety, and tolerability of AZD0780. Part B will be the Phase III study and aims to evaluate the reduction of LDL-C as well as the safety and tolerability after oral administration of AZD0780 on background lipid-lowing therapy including moderate to high-intensity statins.

For Part A, approximately 60 participants who meet the eligibility criteria will be randomised. Part A will comprise 4 periods totalling up to 80 days.

For Part B, approximately 220 participants who meet the eligibility criteria will be randomised in Cohort 1, and approximately 100 participants who meet the eligibility criteria will be randomised in Cohort 2.

Cohort 1: participants are on a stable dose of LLTs, including moderate to high-intensity statins for≥ 28 days before screening.

Cohort 2: participants could be with moderate-intensity or without statins therapy (not due to statin intolerance) in background LLTs or not on any LLTs .
