Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a prospective, randomized, open-label, and single center trial. To evaluate the effect of treatment with PCSK9 inhibitor on the risk for cardiovascular death, recurrent unstable angina, myocardial infarction, stroke, or coronary revascularization in patients with very high risk of atherosclerotic cardiovascular disease (ASCVD) and cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Subjects will be randomly assigned in a 1:1 ratio to receive subcutaneous injections of PCSK9 inhibitor (evolocumab:420 mg every 4 weeks) plus moderate intensity statin therapy or the statin alone therapy. After randomization, patients will come to the hospital every 4 weeks to collect relevant laboratory results and clinical outcomes, and be detected by echocardiography and carotid ultrasound every 12 weeks until the end of follow-up at week 48 or the occurrence of an endpoint event. The entire study is expected to be conducted for 3 years, with a recruitment period of 2 years.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Unequivocally documented ASCVD on imaging includes those findings that are known to be predictive of clinical events, such as significant plaque on coronary angiography or computed tomography (CT) scan (multivessel coronary disease with two major epicardial arteries having \>50% stenosis), or on carotid ultrasound.
2. Diabetes mellitus (DM) with target organ damage, or at least three major risk factors, or early onset of type 1 diabetes mellitus (T1DM) of long duration (\>20 years).
* Patients have been diagnosed with cancer through histopathology and have a life expectancy of more than 1 year
* Fasting low-density lipoprotein cholesterol (LDL-C) ≥ 1.8 mmol/L or non-high-density lipoprotein cholesterol (non HDL-C) \> 2.6 mmol/L
* Participate voluntarily and sign an informed consent
* Negative serum Pregnancy test (in women with fertility potential)

Exclusion Criteria

* Pregnant and lactating women
* During the study period and within 3 months of receiving the last dose of the study drug, women with fertility intentions and men unwilling to use effective contraceptive methods
* New York Heart Association (NYHA) class III or IV, or last known left ventricular ejection fraction \< 30%
* Uncontrolled hypertension, defined as systolic blood pressure ≥ 180 mmHg and/or diastolic blood pressure ≥ 110 mmHg
* Plan for coronary revascularization or other cardiac surgery in recent (within 3 months after randomization)
* Severe renal insufficiency, defined as estimated glomerular filtration rate (eGRF) \< 30ml/min/1.73m2 or Serum creatinine (Scr) \> 221 umol/L
* Severe liver dysfunction, defined as an increase in alanine aminotransferase (ALT) or aspartate aminotransferase (AST) more than 3 times above the upper limit of normal
* Have used PCSK9 inhibitors within 3 months before enrollment, or have a history of severe allergic reactions to PCSK9 inhibitors
* Severe infections requiring intravenous antibiotics
* HIV-positive or history of acquired immunodeficiency syndrome (AIDS)
* With cognitive impairment or psychiatric illnesses
