Eligibility

Recruits 128 Vulnerable population flag is selected in the record. Signed informed consent must be obtained prior to participation in the study. Only adults aged 18 to 80 years are eligible. Subject information and informed consent form documents are provided (adult ICFs present in German and English). No assent process or additional consent arrangements for minors or other vulnerable groups are described in the available documents..

Vulnerable Population
Vulnerable population flag is selected in the record. Signed informed consent must be obtained prior to participation in the study. Only adults aged 18 to 80 years are eligible. Subject information and informed consent form documents are provided (adult ICFs present in German and English). No assent process or additional consent arrangements for minors or other vulnerable groups are described in the available documents.

Inclusion criteria

  • {"criterion_text":"- Signed informed consent must be obtained prior to participation in the study."}
  • {"criterion_text":"- Male or female participants 18 to 80 years of age (inclusive) at the screening."}
  • {"criterion_text":"- Lp(a) ≥ 150 nmol/L at screening, measured at the central laboratory."}
  • {"criterion_text":"- Presence of ASCVD and/or Type 2 diabetes mellitus (T2DM). Diagnosis of ASCVD should be based on at least one of the following: a. Coronary heart disease (CHD): • Prior myocardial infarction (MI) of presumed atherosclerotic origin, which occurred ≥ 12 weeks prior to the Screening Visit • Prior coronary revascularization (PCI or CABG) that occurred ≥ 12 weeks prior to the Screening Visit • Angiographic or CT-imaging (e.g., MDCT/CTA) evidence of coronary atherosclerosis: ≥50% stenosis in at least one major epicardial coronary artery • Coronary artery calcium (CAC) score of ≥ 300 AU by computed tomography (if a participant has T2DM CAC score of ≥ 100 AU is sufficient to define ASCVD) And/or b. Cerebrovascular disease (CeVD): • Prior ischemic stroke, which occurred ≥ 12 weeks prior to the Screening Visit, confirmed by documented brain imaging (CT or MRI); embolic stroke (not of atherosclerotic origin) is not a qualifying event. • History of percutaneous or surgical carotid artery revascularization that occurred ≥ 12 weeks prior to the Screening Visit • Carotid artery stenosis ≥ 70% or symptomatic carotid artery disease with ≥ 50% carotid arterial stenosis on prior angiography or ultrasound And/or c. Peripheral arterial disease (PAD): • Prior non-traumatic amputation of a lower extremity due to peripheral artery disease • History of prior percutaneous or surgical revascularization of iliac, femoral, or popliteal artery • Prior documentation of a resting ankle-brachial index ≤ 0.9 On standard of care treatment for ASCVD risk factors (according to local guidelines and per Investigator discretion). Participants receiving lipid lowering therapy (including statins, ezetimibe, proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibody inhibitors must be on a stable regimen per local guidelines prior to screening, with no planned changes made after screening, and expected to remain on a stable regimen through the end of the treatment (as statins may raise Lp(a) concentrations). A stable dose is defined as at least 8 weeks of treatment at a consistent dose level for monoclonal antibody PCSK9 inhibitors, and at least 4 weeks for all other LLT."}

Exclusion criteria

  • {"criterion_text":"- Acute cardiovascular event (e.g., acute myocardial infarction or unstable angina, CABG, stroke, TIA) within 12 weeks before screening"}
  • {"criterion_text":"- Renal dysfunction with eGFR ≤ 30 mL/min/1.73 m2 (using CKD-EPI formula) at screening"}
  • {"criterion_text":"- Positive human immunodeficiency virus (HIV), hepatitis C, or hepatitis B surface antigen tests from central laboratory at Screening Visit."}
  • {"criterion_text":"- Hepatic dysfunction based on liver function tests at screening (defined as AST or ALT > 2 × ULN or total bilirubin > 1.5 × ULN at screening) (participants with Gilbert’s syndrome are allowed if total bilirubin < 2 × ULN)"}
  • {"criterion_text":"- Current or prior history of moderate to severe heart failure of NYHA Class III or IV, or known LVEF < 30% at screening"}
  • {"criterion_text":"- Uncontrolled cardiac arrhythmia"}
