Amgen's Repatha FOURIER cardiovascular outcomes study meets primary & key secondary endpoint
Amgen has announced that the FOURIER trial evaluating whether Repatha (evolocumab) reduces the risk of cardiovascular events in patients with clinically evident atherosclerotic cardiovascular disease (ASCVD) met its primary composite endpoint (cardiovascular death, non-fatal myocardial infarction (MI), non-fatal stroke, hospitalization for unstable angina or coronary revascularization) and the key secondary composite endpoint (cardiovascular death, non-fatal MI or non-fatal stroke). No new safety issues were observed.
The ebbinghaus cognitive function trial conducted in FOURIER patients also achieved its primary endpoint, demonstrating that Repatha was non-inferior to placebo for the effect on cognitive function.
Detailed results from the Repatha FOURIER outcomes trial will be presented at the American College of Cardiology (ACC) 66th annual scientific session late-breaking clinical trials session in Washington, D.C. on March 17. Detailed results from the Repatha ebbinghaus cognitive function trial will be presented at the late-breaking clinical trials session on March 18.
"In the glagov study, we demonstrated that Repatha has an effect on atherosclerosis, the underlying cause of cardiovascular disease. These FOURIER results show unequivocally the connection between lowering LDL cholesterol with Repatha and cardiovascular risk reduction, even in a population already treated with optimized statin therapy," said Sean E. Harper, managing director, executive vice president of Research and Development at Amgen. "Cardiovascular disease remains the number one health burden in the world, and we look forward to sharing these outcomes data with the scientific community at the ACC 66th annual scientific session."
Fourier, is a multinational phase 3 double-blind, randomized, placebo-controlled trial in approximately 27,500 patients who had either an MI, an ischemic stroke or symptomatic peripheral artery disease and an LDL =70 mg/dL or a non-HDL-C =100 mg/dL on optimized statin therapy. Optimized statin therapy was defined as at least atorvastatin 20 mg or equivalent daily with a recommendation for at least atorvastatin 40 mg or equivalent daily where approved. Patients were randomized to receive Repatha subcutaneous 140 mg every two weeks or 420 mg monthly or placebo subcutaneous every two weeks or monthly. The study continued until at least 1,630 patients experienced a key secondary MACE (major adverse cardiac event) endpoint of cardiovascular death, MI or stroke, whichever occurred first.
Ebbinghaus (Evaluating PCSK9 Binding antiBody Influence oN coGnitive HeAlth in high cardiovascUlar risk Subjects) is a double-blind, placebo-controlled randomized non-inferiority trial involving approximately 1,900 patients enrolled in the Fourier outcomes study. Executive function (Spatial Working Memory strategy index – primary endpoint) and secondary endpoints of working memory, memory function, and psychomotor speed were assessed using a tablet-based tool (CANTAB) at baseline and select time points.
Cardiovascular disease is the leading cause of death worldwide.1 In the US, there are approximately 11 million people with ASCVD and/or familial hypercholesterolemia (FH) who have uncontrolled levels of low-density lipoprotein (LDL-C) over 70 mg/dL, despite treatment with statins or other cholesterol-lowering therapies. More than 60 per cent of high-risk patients in Europe are still unable to adequately lower their LDL-C levels with statins or other currently approved lipid-lowering agents. Among very high-risk patients, the percentage is increased to more than 80 per cent. It is estimated that less than one percent of people with FH (heterozygous and homozygous forms) in most countries are diagnosed.
