Risk Evaluation With AI-CPA + HCS For Patients IN Whom Calcium is confirmEd to Improve Coronary Artery Disease Care

Source: ClinicalTrials.gov · Last updated 2 Oct 2026

Brief summary (registry, in English)

REFINE-CAC is a prospective, multi-center trial assessing the management of asymptomatic participants with CAC scores 1-299 Agatston units or incidental CAC findings on chest computed tomography (CT), all of whom will undergo CCTA and are blinded to the coronary anatomy (e.g., % stenosis). The trial includes a randomized, controlled pathway and a single arm, observational registry pathway.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • On PCSK9 targeted therapy (e.g. evolocumab, alirocumab, inclisiran, or enlicitide)
  • Prior history of ASCVD
  • Prior coronary artery bypass graft (CABG)
  • Prior percutaneous coronary intervention (PCI)
  • Previously evaluated with and/or in a trial which includes AI-CPA
  • Active chemotherapy and/or radiation

Other illness

  • Symptoms suggestive of CAD (e.g. stable angina)
  • Enrolled in an investigational trial that involves a non-approved cardiac drug or device
  • Any condition that might interfere with trial procedures or follow up visits

Lab values

  • Reduced left ventricular ejection fraction (LVEF) \<35%, if known
  • LDL-C \<70 mg/dL at baseline lab draw

Other

  • Life expectancy less than 2 years due to non-CV comorbidities

Who the study is looking for

  • Calcium score between 1-299 between 3-6 months prior to Day 0 or incidental CAC findings on a chest CT between 3 to 6 months prior to Day 0
  • Men ≥40 and ≤79, Women ≥45 and ≤79
  • Patients who do not have symptoms suggestive of CAD
  • Visible plaque on CCTA
  • No other clinical CCTA subsequent to CAC findings but prior to screening
  • No prior history of atherosclerotic cardiovascular disease (ASCVD)
  • Acceptable CCTA quality per Heartflow acceptance criteria
  • eGFR \>45 mL/min per most recent measurement within 90 days
  • Willingness to comply with all aspects of the protocol including research CCTAs, lab draws, medication adherence assessments, attending all study visits, and the ability to comply with prescribed medications
  • For participants of childbearing potential (those who have not been surgically sterilized), a pregnancy test must be performed with negative results known within 7 days prior to randomization
  • Ability to provide informed consent
