ASCVD Management Using CCTA in Prostate Cancer Patients on ADT

February 23, 2026 updated by: Abhishek Khemka, Indiana University

Personalized Medical Treatment of Coronary Atherosclerosis in Prostate Cancer Patients Guided by Plaque Assessment With Quantitative Coronary CT Angiography (CCTA)

This is a randomized pilot study of Coronary CT Angiography (CCTA) for coronary atherosclerosis vs. Usual Care in patients with prostate cancer who are either planning to begin, or are currently taking androgen deprivation therapy (ADT) .

Detailed Description

This is a randomized pilot study where subjects are randomized 1:1 to either the CCTA group or non-CCTA (usual care) group. The target enrollment will be 100 subjects with accounting for a potential 10% dropout rate resulting in an sample size between 90-100 participants or 45-50per group arm.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Written informed consent and HIPAA authorization for release of personal health information
  2. Age ≥40 years at time of consent
  3. Previous diagnosis of prostate cancer who are either currently receiving ADT, or who are planning to start ADT for >12 months
  4. Patients currently on or planned for treatment with ADT plus androgen pathway inhibitor (abiraterone, enzalutamide, apalutamide, darolutamide) are allowed
  5. ≥1 risk factor for ASCVD (hypertension, hyperlipidemia, diabetes, tobacco use)
  6. No current cardiac symptoms

Exclusion Criteria:

  1. Concurrent treatment with chemotherapy (docetaxel, cabazitaxel, mitoxantrone) at time of signing consent
  2. Patient has implantable cardioverter-defibrillator (ICD), or pacemaker
  3. History of coronary stents, obstructive coronary artery disease, myocardial infarction, coronary artery bypass grafting. History of atrial fibrillation
  4. Renal dysfunction with creatinine clearance <35ml/min (calculated by Cockcroft-Gault Equation)
  5. Allergy to iodinated contrast
  6. Contraindication to the medications that may be given to regulate heart rate for the CCTA scan (applicable only to those randomized to the CCTA group)

  7. Patients taking sildenafil or tadalafil for vasodilation, pulmonary hypertension, or BPH

    1. Note: Subjects taking sildenafil or tadalafil for erectile disfunction will still be eligible.

  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Usual Care Group
Experimental: CCTA Group
Device: Coronary CT Angiography (CCTA)
Coronary computed tomographic angiography (CCTA) scan is a highly accurate noninvasive technique for detection of coronary artery plaque.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion of Atherosclerosis in CCTA Arm
Time Frame: Baseline
Proportion of prostate cancer patients without cardiac symptoms in the CCTA arm who are reclassified into a higher risk group using automated plaque assessment from CCTA that would otherwise be classed as low risk for ASCVD using the PCE
Baseline
Proportion of Subjects Eligible for Treatment Based on Automated Plaque Assessment from CCTA
Time Frame: Baseline
Assessment of automated plaque from CCTA determining eligibility of lipid lowering treatment and aspirin
Baseline

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Reduction in atherosclerotic cardiovascular disease (ASCVD) risk score
Time Frame: Baseline, 6 months, and 12 months
Changes in risk over time with intensive medical treatment tailored to plaque burden to test results in a reduction in cardiovascular risk factors including blood pressure, glucose and lipid levels, thus reducing the ASCVD risk score.
Baseline, 6 months, and 12 months
