About this study

Official title: The Impact of Ticagrelor on Coronary Atherosclerotic Lipid Pool and Inflammation Assessed by Near-Infrared Spectroscopy

The Impact of Ticagrelor on Coronary Atherosclerotic Lipid Pool and Inflammation Assessed by Near-Infrared Spectroscopy study will evaluate whether ticagrelor leads to a 20% reduction in the LCBI with NIRS/IVUS suggesting coronary plaque stabilization and reduced inflammation in patients already on long-term statin therapy undergoing non-urgent PCI. It is hypothesized that the treatment with ticagrelor following PCI will lead to a significant 20% reduction in the lipid pool as measured by NIRS/IVUS at follow-up when compared with baseline imaging, suggesting a reduction in inflammation and stabilization of the lipid core in atherosclerotic lesions not treated during the index procedure.

Read the detailed description

Single-Center, open-label study of the effect of ticagrelor on the reduction in the lipid pool in 30 patients with multi-vessel CAD 2 Treatment periods over 6 months, with 2 additional follow-up phone calls at 1 and 3 months.

Non-urgent PCI requiring stent placement and evaluation by NIRS/IVUS at baseline and 6 month follow up A second concomitant coronary lesion with diameter stenosis greater than 50% will also be imaged using NIRS/IVUS.

Patients will be discharged on a ticagrelor regiment of 90 mg twice a day for the 6 month study.

Blood samples will be drawn at baseline prior to ticagrelor being administered and again at follow up.

Inclusion Criteria:

  • Female (post menopausal or surgically sterile) and/or male aged 18 years or older
  • Multi-vessel coronary artery disease
  • Statin therapy for minimum of 6 weeks prior to enrollment in the study with no plan for further adjustment
  • Non-emergent PCI for ACS with stent placement requiring dual-antiplatelet therapy
  • Ability to safely perform NIRS/IVUS for a concomitant non-culprit lesion with diameter stenosis ≥ 50% that was not treated with PCI
  • Willing and able to sign informed consent and participate in follow-up

Exclusion Criteria:

  • Thienopyridine or ticagrelor use in the last month
  • Need for coronary artery bypass surgery or other surgeries during the follow-up period
  • Documented medication non-compliance
  • Chronic inflammatory disorder or treatment with anti-inflammatory or immunosuppressive drugs
  • Prior or current malignancy within the last 5 years
  • Concomitant severe illness or reduced life expectancy that will prevent follow-up cardiac catheterization
  • Active infection
  • Pregnant or lactating women
  • End-stage renal disease
  • History of intracranial hemorrhage
  • Active pathological bleeding
  • Known sever hepatic impairment
  • Known hypersensitivity to ticagrelor

Study Procedures:

After consent is obtained non-urgent PCI requiring stent placement and evaluation by NIRS/IVUS at baseline is performed and once again at 6 month follow up. A second concomitant coronary lesion with diameter stenosis greater than 50% will also be imaged using NIRS/IVUS. Patients will be discharged on a ticagrelor regiment of 90 mg twice a day for the 6 month study.Blood samples will be drawn at baseline prior to ticagrelor being administered and again at follow up. There will be 1 month phone follow up, 3 month phone follow up and a 6 month clinical follow up that includes collecting blood, repeat catheterization, and repeat NIRS/IVUS procedure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline Lipid Pool to Follow up as Assessed by NIRS/IVUS With Treatment of Ticagrelor

    Treatment with ticagrelor following PCI will lead to significant 20% reduction in the LCBI as assessed at follow up by NIRS/IVUS when compared with baseline imaging data of the reference vessel, suggesting a reduction in inflammation and stabilization of the lipid core in atherosclerotic lesions not treated during the index procedure.

    Measured: 6 months

Secondary outcomes (1)
  1. Change From Baseline Inflammatory Markers to Follow up With Treatment of Ticagrelor

    We expect to see a significant reduction of inflammatory markers of Hs-CRP, MCP-1, IL-1, IL-6, IL-18, and TNF- α as well as an increase in IL-10, a cytokine associated with a reduction in inflammation, following therapy with ticagrelor when compared with baseline values. This is expected as inflammatory markers should be lower in stable coronary artery disease compared with patients presenting with ACS. While there is no control group in the proposed study, it will be important to assess whether changes in established biomarkers associated with inflammation correlate with changes in LCBI. While ticagrelor was not shown to reduce inflammatory biomarkers to a greater degree than clopidogrel, it will be important to assess whether the reduction in LCBI is independent of or associated with reductions in inflammatory markers or platelet reactivity.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Ticagrelor in people with Coronary Artery Disease, run by Medstar Health Research Institute.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Apr 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline Lipid Pool to Follow up as Assessed by NIRS/IVUS With Treatment of Ticagrelor (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Apr 2021.
