Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This is a trial to see if deferasirox (pronounced de-fer-a-sir-ox) helps people with myelodysplastic syndrome who have too much iron in their blood due to a lot of blood transfusions.
Myelodysplastic syndrome (MDS) is a condition affecting the . If you have MDS, your bone marrow makes abnormal blood cells, but not enough healthy blood cells. MDS can sometimes develop into acute myeloid leukaemia (AML).
Depending on the number of abnormal cells in your bone marrow, doctors work out if there is a low, medium (intermediate) or high risk of your MDS becoming leukaemia. This trial is for people who have low or intermediate risk MDS.
MDS can lead to problems such as infections, bleeding and a low number of red blood cells (). Doctors can treat anaemia with
. This helps control the symptoms, but can lead to an overload of iron in your bloodstream, which can cause problems in your
. It may also affect your heart. So people who have a lot of blood transfusions may also need drugs to reduce the amount of iron. These are called iron chelators (pronounced kee-lay-tors).
In this trial, the researchers are looking at an iron chelator that you can take by mouth. It is called deferasirox or Exjade. It is already licensed to treat iron overload. The aim of this trial is to find out if it helps people with MDS.

This is an international trial. It will recruit about 630 people around the world. 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. You will not know which group you are in either. This is called a double blind trial.
People in 1 group take deferasirox tablets once a day. The trial doctors will work out the right dose for you according to how much you weigh and tell you exactly how many tablets to take. You have to mix the tablets into a glass of water or fruit juice before swallowing them.
People in the other group take dummy tablets (). They look exactly the same as the deferasirox tablets and you take them in the same way.
You take the tablets for between 3 and 5 years. This will depend on how many people have joined the trial before you. The trial team estimate that it will take about 2 years to recruit enough people. Those joining at the beginning will take the tablets for longer than people joining later on. During the trial, the doctors may change your dose depending on your blood test results.
You will see the doctors and have some tests before you start treatment. The tests include
You see the trial doctors at least once every 4 weeks, more often in the first month of treatment. During the trial you have more blood tests, ECGs, echocardiograms, eye and hearing tests. Your doctors may want you to have more bone marrow tests, ultrasound scans or chest X-rays.
When you finish treatment, a member of the trial team will phone you 4 weeks later to see how you are. The trial team will continue to follow your progress by phone every 6 months until the study is completely over.
If you decide to stop having the trial treatment early, or have to stop because of side effects, the trial team would like to continue to monitor your condition. You will have blood tests, an ECG and echocardiogram every 3 months, as well as eye and hearing tests once a year. If you no longer want to attend these visits, they will contact you by phone to see how you are every 6 months until study is completely over.
The possible side effects of deferasirox include
Occasionally, deferasirox can cause hair thinning or hair loss. Very occasionally it can cause an allergic reaction leading to breathing problems and swelling of the face or throat.
Please note: In order to join a trial you will need to discuss it with your doctor, unless otherwise specified.
