A trial of tranexamic acid for low platelet counts (TREATT)
This trial is looking at using a drug called tranexamic acid to treat low platelet counts caused by cancer. The trial is open to people with a
More about this trial
Bleeding can be a problem for people with a haematological malignancy. This could be because of the cancer itself or from treatment such as high dose chemotherapy or stem cell transplant.
Doctors sometimes give these people a
In this trial the researchers will do blood tests to check on the number of platelets in your blood. When the platelets drop below a certain level you will have either the tranexamic acid or a dummy drug (
The aims of this trial are to find out
- If tranexamic acid can reduce bleeding for people with haematological malignancies
- If the need for platelet transfusions is reduced
- How this affects

This is an international phase 3 trial. The researchers need 616 people in the UK to join.
It is a randomised trial. The people taking part are put into treatment groups by a computer. Neither you nor your doctor will be able to decide which group you are in. And neither of you will know which group you are in. This is called a double blind trial.
You will be entered into the trial and have daily blood tests to check the number of platelets in your blood. When your platelet count drops to a certain level you will be put into 1 of the 2 treatment groups.
- People in one group have tranexamic acid
- People in the other group have a dummy drug (placebo)
To begin with you have tranexamic acid or the dummy drug as an injection into a vein 3 times a day. When you are well enough you can change to having 3 capsules 3 times a day.
You have treatment for up to 30 days as long as it is helping you and your platelet count remains low. If you leave hospital before the end of the 30 days you will have capsules to take at home.
During treatment a member of the trial team will see you every morning to ask a few questions about any signs or symptoms of bleeding. They will also look at your skin and in your mouth. If you go home before finishing treatment, you have a simple diary card to fill in each day to record any signs or symptoms of bleeding.
The trial team will ask you to fill out a questionnaire before you start treatment and 12 weeks later. The questionnaire will ask about side effects and how you’ve been feeling. This is called a quality of life study.
You continue to have your usual treatment for your haematological malignancy alongside the trial treatment.
It is likely you will be in hospital for the start of the trial treatment.
A month and 3 months after treatment, a member of the team will see you in hospital, or phone you, to see how you are.
Tranexamic acid is used in other medical conditions that can cause bleeding. Although it may cause unwanted blood clots this has not been a problem in these conditions. When used for a short time there have been no reported side effects.
The trial team are not certain if this will be the same for someone with your condition. So the trial team, your doctor and the nurses will monitor you carefully for blood clots and any other problems.
