Eligibility criteria

Key Inclusion Criteria

  • Lp(a) ≥ 70 mg/dL at the screening visit, measured at the Central laboratory
  • Myocardial infarction: ≥ 3 months from screening and randomization to ≤ 10 years prior to the screening visit
  • Ischemic stroke: ≥ 3 months from screening and randomization to ≤ 10 years prior to the screening visit
  • symptomatic peripheral artery disease

Key Exclusion Criteria

  • Uncontrolled hypertension
  • Heart failure (NYHA) class IV
  • History of of any organ system
  • History of hemorrhagic stroke or other major bleeding
  • count ≤LLN
  • Active liver disease or hepatic dysfunction
  • Significant kidney disease
  • Pregnant or nursing women

Other protocol-defined inclusion/exclusion criteria may apply at the end.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

What researchers measure

Primary outcomes

  1. Time to first occurrence of clinical endpoint committee confirmed expanded major adverse cardiovascular events in patients with elevated Lp(a) ≥ 70 mg/dL

    Demonstrate the superiority of pelacarsen (TQJ230) compared to placebo in reducing the risk of expanded MACE (cardiovascular death, non-fatal MI, non-fatal stroke and urgent coronary re-vascularization requiring hospitalization) in the overall study population with established CVD and (Lp(a) ≥ 70 mg/dL)

    Time frame: approximately 4 years

  2. Time to the first occurrence of clinical endpoint committee confirmed expanded major adverse cardiovascular events in a population of patients with elevated Lp(a) ≥ 90 mg/dL.

    Demonstrate the superiority of pelacarsen (TQJ230) compared to placebo in reducing the risk of expanded MACE (cardiovascular death, non-fatal MI, non-fatal stroke and urgent coronary re-vascularization requiring hospitalization) in the overall study population with established CVD and (Lp(a) ≥ 90 mg/dL)

    Time frame: approximately 4 years

Secondary outcomes

  1. Time to the first occurrence of the clinical endpoint committee confirmed composite endpoint of major adverse cardiovascular events (CV death, non-fatal MI, and non-fatal stroke)

    Demonstrate the superiority of pelacarsen (TQJ230) compared to placebo in reducing the risk of the MACE composite of CV death, nonfatal MI and non-fatal stroke.

    Time frame: approximately 4 years

  2. Time to the first occurrence of the clinical endpoint committee confirmed composite endpoint of coronary heart disease: coronary heart disease death, non-fatal MI, urgent coronary re-vascularization requiring hospitalization

    Demonstrate the superiority of pelacarsen (TQJ230) compared to placebo in reducing the risk of the composite of coronary heart disease (CHD) outcomes: death due to CHD, nonfatal MI and urgent coronary revascularization requiring hospitalization.

    Time frame: approximately 4 years

  3. Time to Clinical endpoint Committee confirmed all-cause death

    Evaluation by clinical endpoint committee the rate of all-cause death

    Time frame: approximately 4 years

  4. Change in Lp(a) in the log scale from baseline

    Demonstrate the superiority of pelacarsen (TQJ230) compared to placebo in lowering the Lp(a) level at 1 year

    Time frame: Baseline, year 1
