LDL Cholesterol TARGETs in OLDer Patients (Age≥75 Years) With ASCVD (TARGET OLD)

Sponsor: China National Center for Cardiovascular Diseases

View on ClinicalTrials.gov

Summary

To determine whether treating to an LDL-C target of 25 to \<70 mg/dL is superior to an LDL-C target of 70 to \<100 mg/dL with respect to major cardiovascular events (cardiovascular death, myocardial infarction, stroke, hospitalization for unstable angina, or coronary revascularization) in patients aged ≥75 years with atherosclerotic cardiovascular disease (ASCVD). To determine whether treating to an LDL-C target of 25 to \<70 mg/dL is non-inferior to an LDL-C target of 70 to \<100 mg/dL with respect to major safety events (hemorrhagic stroke, new-onset diabetes, muscle-related events, neurocognitive adverse events, new or recurrent cancer, cataract, or hepatic disorder \[Alanine aminotransferase (ALT)/Aspartate aminotransferase (AST) \>3× ULN, or total bilirubin \>2× ULN\]) in patients aged ≥75 years with ASCVD.

PROCEDURE

Achieving a Target LDL-C level of 25mg/dL≤ LDL-C<70mg/dL

Investigators initiated or adjusted lipid-lowering agents (drug and dosage) to achieve the target of 25mg/dL≤ LDL-C\<70mg/dL. The protocol encouraged, but did not mandate, the initiation of moderate-intensity statin therapy for secondary prevention with the evaluation of the potential for ASCVD risk reduction, adverse effects, and drug-drug interactions, as well as patient frailty and patient preferences. Statin monotherapy or in combination with ezetimibe, PCSK9 inhibitor or other drugs were adjusted on the basis of LDL-C levels. At each follow-up visit, the investigators should verify whether the target LDL-C has been obtained. If the target level of LDL cholesterol was achieved, it is reasonable to continue to monitor adherence to lifestyle modiﬁcations, medication, and ongoing LDL-C response to therapy. If the target level of LDL cholesterol was not achieved, adjustment of the type and dose regimen of statin, or the additional of a nonstatin agent should be considered.

Inclusion Criteria: 1. Men or women ≥75 years of age 2. Diagnosis of clinical atherosclerotic cardiovascular disease (ASCVD) with one or more of the following: 1. Diagnosis of coronary heart disease (one or more of the following criteria must be satisfied): * Hospitalization for acute coronary syndrome * Treatment or hospitalization for stable angina pectoris with documented ischemia on invasive or noninvasive testing * History of myocardial infarction * History of coronary revascularization procedure (eg, percutaneous coronary intervention \[PCI\] or coronary artery bypass graft surgery \[CABG\]) * Invasive diagnostic coronary angiography indicating \>50% stenosis in at least one major epicardial coronary artery or CT-imaging (eg, CCTA/MDCT) evidence of coronary atherosclerosis (\>50% stenosis in at least two major epicardial coronary artery) 2. Diagnosis of atherosclerotic cerebrovascular or carotid disease (one or more of the following criteria must be satisfied): * History of ischemic stroke or transient ischemic attack (TIA) confirmed by symptoms with a documented ischemic lesion on CT or MRI in the cerebral regions corresponding to the symptoms; * Documented intracranial atherosclerotic stenosis on the basis of conventional cerebral angiography, magnetic resonance angiography, CT angiography, transcranial doppler ultrasound, and high-resolution MRI; * Symptomatic carotid artery disease with ≥50% carotid arterial stenosis; * Asymptomatic carotid artery disease with ≥70% carotid arterial stenosis per angiography or duplex ultrasound; * History of carotid revascularization (catheter-based or surgical). 3.
