What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying the effects of a treatment for patients with coronary artery disease, a condition where the blood vessels supplying the heart become narrowed or blocked. The study will explore the use of a medication called ticagrelor, which is often used to prevent blood clots, in combination with acetylsalicylic acid (commonly known as aspirin), compared to using aspirin alone. The trial is named "The One-Month DAPT with Ticagrelor In CABG Patients Trial (ODIN)." The purpose of the study is to compare the effects of these treatments on the occurrence of heart-related events and the success of heart bypass surgery over a period of one year.

Participants in the study will be patients undergoing a type of heart surgery known as CABG (Coronary Artery Bypass Grafting), which is performed to improve blood flow to the heart. The study will last for one month, during which participants will receive either the combination of ticagrelor and aspirin or aspirin alone. The researchers will then monitor the participants for one year to assess the incidence of heart-related events such as heart attacks, strokes, and any issues with the grafts used in the surgery.

The study aims to provide valuable information on whether the combination of ticagrelor and aspirin is more effective than aspirin alone in reducing the risk of heart-related events after CABG surgery. This information could help improve treatment strategies for patients with coronary artery disease undergoing this type of surgery. Participants will be followed up for a total of five years to gather long-term data on their health and quality of life.

The research process

The trial runs in 4 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Joining the study

    Upon joining the study, eligibility is confirmed based on criteria such as age (18 years or older), undergoing elective first-time coronary artery bypass grafting (CABG) with at least one saphenous vein graft, and having chronic coronary disease.

    Consent is required to participate and comply with study procedures, including follow-up for at least 5 years.

  2. Step 2

    Medication administration

    The study involves taking medications orally. The medications include ticagrelor and acetylsalicylic acid (ASA).

    Ticagrelor is administered as 90 mg film-coated tablets, and ASA is provided in various forms such as 100 mg gastro-resistant tablets and 75 mg tablets.

    The treatment duration with ticagrelor in addition to ASA is for 1 month.

  3. Step 3

    Monitoring and follow-up

    The primary goal is to assess the effect of ticagrelor in addition to ASA versus ASA alone on the 1-year incidence of ischemic events and graft failure.

    Monitoring includes evaluating the time to death, stroke, heart attack, repeat revascularization, and any graft failure at 1 year.

    Secondary assessments include the same events plus bleeding and quality of life scores over 5 years.

  4. Step 4

    Completion of study

    The study is expected to conclude by March 30, 2030.

    Participants are followed up for at least 5 years to gather comprehensive data on the long-term effects of the treatment.

Who can join the trial?

6 criteria

  • Must be **18 years old** or older.
  • Scheduled for a **first-time elective CABG**. CABG stands for **Coronary Artery Bypass Grafting**, which is a type of heart surgery.
  • Use of at least one **saphenous vein graft** during the surgery. A saphenous vein graft is a vein taken from the leg to help improve blood flow to the heart.
  • Must be able to **sign informed consent**. This means you understand the study and agree to participate.
  • Must be able to **follow all study procedures** and attend follow-up visits for at least 5 years.
  • Have **chronic coronary disease**. This is a long-term condition affecting the blood vessels of the heart.

Who cannot join the trial?

9 criteria

  • Patients who have a history of severe allergic reactions to the study medications.
  • Patients with active bleeding or a high risk of bleeding.
  • Patients who have had a stroke or a mini-stroke (also known as a transient ischemic attack) in the past 6 months.
  • Patients with severe liver disease.
  • Patients who are currently taking medications that strongly interact with the study drugs.
  • Patients with a history of drug or alcohol abuse within the past year.
  • Patients who are pregnant or breastfeeding.
  • Patients who have participated in another clinical trial within the last 30 days.
  • Patients with any other medical condition that the study doctors believe would make it unsafe for them to participate.

Investigated drugs

  • Ticagrelor

    is a medication used to prevent blood clots in patients who have had a heart attack or are undergoing certain heart procedures. In this trial, it is being tested to see if it can reduce the risk of ischemic events and graft failure in patients who have had coronary artery bypass grafting (CABG) surgery.

  • ASA

    , also known as aspirin, is a common medication used to reduce pain, fever, or inflammation. It is also used to prevent blood clots in patients with heart conditions. In this trial, ASA is being used alone and in combination with ticagrelor to see its effectiveness in preventing complications after CABG surgery.

What is already known about the treatment

Ticagrelor – Ticagrelor is administered orally in tablet form. It is currently being studied in clinical trials for its effectiveness in patients with coronary artery disease, particularly those undergoing coronary artery bypass grafting (CABG). The main therapeutic indication for Ticagrelor is to reduce the risk of ischemic events, such as heart attacks, by preventing blood clots. At the molecular level, Ticagrelor works by inhibiting a receptor on platelets, which are cells involved in blood clotting, thus reducing their ability to clump together. It is classified as an antiplatelet medication.

Investigated diseases

Coronary Artery Disease – This condition occurs when the major blood vessels that supply the heart with blood, oxygen, and nutrients become damaged or diseased, primarily due to the buildup of cholesterol and other substances, known as plaque, on the artery walls. Over time, this plaque can harden or rupture, leading to narrowed or blocked arteries, which reduces blood flow to the heart. As the disease progresses, it can cause chest pain, shortness of breath, or other symptoms, especially during physical activity or stress. If the blood flow becomes severely restricted or blocked, it can result in a heart attack. The progression of coronary artery disease can vary, with some individuals experiencing rapid worsening of symptoms, while others may have a more gradual development.
