AZD0780, a novel oral PCSK9 inhibitor, demonstrated significant LDL cholesterol (LDL-C) reduction in PURSUIT Phase IIb trial
New late-breaking clinical trial data presented at ACC and published simultaneously in JACC show benefit of investigational medicine AZD0780 on top of standard of care
These new data were presented today at the American College of Cardiology’s (ACC) Annual Scientific Session & Expo in
At 12 weeks, AZD0780 30mg taken once-daily (when added to the standard-of-care statin therapy and administered without any fasting or food restrictions) led to a
High LDL-C (≥70 mg/dL), a common type of dyslipidemia, is a key risk factor for atherosclerotic cardiovascular disease, including stroke and heart attack, and a significant public health concern.3 It is estimated that more than
Dr. Michael J Koren, MD, CEO & Medical Director of Jacksonville Center for Clinical Research,
Sharon Barr, Executive Vice President, BioPharmaceuticals R&D, AstraZeneca, said: “These new data reflect AZD0780’s ability to reduce LDL cholesterol in patients who need more options to manage their cholesterol and related risks when standard-of-care therapy is not enough. As a novel small molecule oral PCSK9 inhibitor that can be taken without fasting restrictions, AZD0780 has the potential to be a game changer that could offer LDL-C lowering with greater convenience for patients. Our work in dyslipidemia builds on our strong heritage in cardiovascular, renal and metabolic diseases where we are advancing novel therapies, alone or in combination with other molecules in our extensive portfolio, that could redefine treatment standards and patient outcomes.”
AZD0780 was generally well tolerated, and adverse events (AEs) were comparable between the total AZD0780 treatment groups (
Data from PURSUIT are consistent with Phase I findings presented at European Atherosclerosis Society (EAS) 2024.8

About Dyslipidemia
Elevated LDL-C levels in plasma is a key risk factor for cardiovascular disease and is estimated to cause 4.4 million deaths worldwide annually.3 Despite current treatment options, the global burden of dyslipidemia is on the rise.4 More than
PURSUIT
PURSUIT is a Phase IIb, multicenter, randomized, parallel-group, double-blind, placebo-controlled, dose-ranging study to evaluate the efficacy, safety and tolerability of AZD0780 in participants with dyslipidemia.2
PURSUIT assessed the efficacy, safety and tolerability of different doses of AZD0780 on LDL-C levels in patients with hypercholesterolemia. 428 patients on stable standard-of-care therapy with moderate- or high-intensity statins with or without ezetimibe with LDL-C levels ≥70 and <190 mg/dL were randomized (1:1:1:1:1) to receive AZD0780 (1 mg, 3 mg, 10 mg and 30 mg daily) or matching placebo. 426 patients started treatment.2
The primary objective of the study was to measure the effect of different doses of AZD0780 given once daily on LDL-C levels in patients with dyslipidemia receiving standard-of-care statins. The effect of AZD0780 versus placebo on other lipid parameters and inflammatory markers was also investigated. The concentration of AZD0780 in blood at specific timepoints was measured, and the safety and tolerability of AZD0780 evaluated.2
AZD0780
AZD0780 is an oral, small molecule PCSK9 inhibitor that is being developed by AstraZeneca as an innovative therapy for patients with elevated low-density lipoprotein cholesterol (LDL-C) levels which cannot be controlled by statins alone.2 PCSK9 is a well-known and validated target in LDL-C metabolism and inhibiting PCSK9 signalling has shown to be effective in reducing LDL-C levels in plasma.2 Lower LDL-C levels are associated with a reduction in the risk of long-term cardiovascular disease and major cardiovascular events.9 AstraZeneca is investigating the potential of AZD0780 as an oral small-molecule for use as a monotherapy or in fixed-dose combinations with other therapies in our extensive portfolio. Data from PURSUIT are consistent with Phase I findings for AZD0780 which demonstrated a statistically significant reduction of
AstraZeneca in CVRM
Cardiovascular, Renal and Metabolism (CVRM), part of BioPharmaceuticals, forms one of AstraZeneca’s main disease areas and is a key growth driver for the Company. By following the science to understand more clearly the underlying links between the heart, kidneys, liver and pancreas, AstraZeneca is investing in a portfolio of medicines for organ protection by slowing or stopping disease progression, and ultimately paving the way towards regenerative therapies. The Company’s ambition is to improve and save the lives of millions of people, by better understanding the interconnections between CVRM diseases and targeting the mechanisms that drive them, so we can detect, diagnose and treat people earlier and more effectively.
