MULTICENTER, DOUBLE BLIND CLINICAL TRIAL TO EVALUATE THE ANTIHEMORRAGIC EFFECT OF THE TOPICAL TRANEXAMIC ACID DURING PACEMAKER IN ANTICOAGULATED PATIENTS
This study is investigating a common medication called tranexamic acid (sometimes shortened to TXA). We want to find out if TXA can help reduce bleeding and bruising (haemorrhage and hematoma) in patients who are taking blood-thinning medicines, such as acenocoumarol, and are having a pacemaker fitted. Pacemakers are small devices that help regulate your heartbeat. People on blood thinners are more prone to bleeding, so this study aims to see if TXA can make the procedure safer by preventing these bleeding-related complications. This is a large-scale study, which is an important step before a new treatment might be widely used.
At a glance
What is this study about?
This research is looking into a medicine called tranexamic acid, often called TXA. Doctors use TXA in hospitals to help stop bleeding. We're interested in whether TXA can be useful for people who are taking blood-thinning medicines, like acenocoumarol, and need to have a pacemaker implanted. Pacemakers are small devices placed under the skin near your heart to help it beat in a regular rhythm.
When you're on blood thinners, your blood doesn't clot as easily, which means you're more likely to bleed or bruise after an operation. This study wants to see if giving TXA during the pacemaker surgery can significantly lower the chances of these bleeding problems occurring. This could make the procedure safer and recovery smoother for many patients.
The study is in its final stages (called Phase III), which means that if it shows good results, TXA could become a more common treatment to prevent bleeding during pacemaker procedures for people on blood thinners. We'll be carefully checking for any bleeding or bruising, but also other things like how long the surgery takes, how long people stay in hospital, and if anyone needs blood transfusions or other medicines.
Key takeaways
- This study evaluates tranexamic acid to reduce bleeding risk.
- It focuses on patients receiving a pacemaker and taking blood thinners.
- Researchers are particularly interested in reducing bleeding and bruising.
- The study is in its final phase before potential wider use.
- Participants may receive the active drug or a dummy drug.
- Your health will be closely monitored throughout the study.
Who may be eligible?
To be part of this study, you would generally need to be an adult, 18 years or older, and male or female. The exact upper age limit is not fixed, so older adults could also be included.
Crucially, you would need to be taking a specific type of blood-thinning medication called acenocoumarol. This study is specifically designed for people on this kind of medication who are also scheduled to have a pacemaker implanted.
There might be other health conditions or medicines that would prevent you from taking part, even if you meet these main criteria. A study doctor would review your full health history to make sure it's safe and appropriate for you to join.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Are you scheduled to have a pacemaker fitted?
- Are you currently taking the blood-thinning medicine called acenocoumarol?
- Are you generally willing to follow study procedures and attend follow-up appointments?
What does participation involve?
If you decide to take part, you would be given the study medication, Amchafibrin (which contains tranexamic acid), or a dummy drug (placebo) during your pacemaker implantation. Neither you nor your doctor would know which one you are receiving – this is called a 'double-blind' study and helps us get the most accurate results.
Throughout your hospital stay and for a period afterwards, the study team would carefully monitor you. They will check for any bleeding or bruising, as well as look at how long your procedure takes, your hospital stay, and if you need any extra treatments like blood transfusions. There will be specific appointments and checks to keep track of your progress and any effects of the medication. The total length of your participation would depend on these follow-up checks.

Common questions
What is a pacemaker and why might I need one?
A pacemaker is a small device that helps your heart beat regularly if it's beating too slowly or irregularly on its own. It's implanted under your skin, usually near your shoulder.
What are blood thinners, and why do they matter for this study?
Blood thinners (like acenocoumarol) are medicines that help prevent blood clots. They are important for many health conditions, but they can also make you more likely to bleed or bruise, especially after surgery. This study aims to reduce that risk.
What is tranexamic acid (TXA)?
TXA is a medicine that helps the blood clot, which can reduce bleeding. It's already used in many medical situations to help stop or prevent excessive blood loss.
What does 'double-blind' mean?
It means that neither you nor the doctors treating you will know if you are receiving the active study drug (tranexamic acid) or a non-active dummy drug (placebo). This helps make the study results fair and unbiased.
Will I still get my usual medical care if I take part?
Yes, taking part in a study will not affect your standard medical care, and your doctors will still look after all your health needs.
