A trial looking at ibrutinib for chronic lymphocytic leukaemia (HELIOS)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at ibrutinib with bendamustine and rituximab for chronic lymphocytic leukaemia (CLL).
If you have chronic lymphocytic leukaemia (CLL), white blood cells called lymphocytes are cancerous. If the cancerous lymphocytes are in your
When CLL stops responding to treatment or has come back after treatment, doctors may use a biological therapy drug and chemotherapy to treat it. They can use the biological therapy drug rituximab and the chemotherapy drug bendamustine. These can help but doctors are always looking for ways to improve treatment.
We know from research that ibrutinib can help people with CLL. The researchers think that giving ibrutinib with rituximab and bendamustine might be better than using just rituximab and bendamustine to treat CLL.
The aim of this trial is to compare ibrutinib, rituximab and bendamustine with rituximab and bendamustine to find out which is best to treat CLL. The researchers also want to find out how safe it is to give ibrutinib with rituximab and bendamustine.

This is an international phase 3 trial. It will recruit 580 people from different countries 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. And neither of you will know which group you are in. This is called a double blind trial.
The groups are
- Bendamustine, rituximab and a dummy drug (placebo)
- Bendamustine, rituximab and ibrutinib
Ibrutinib and the dummy drug are capsules. You take 3 capsules daily. You take them with a glass of water at the same time each day. You take them at least 30 minutes before eating or at least 2 hours after a meal. On the day you have your bendamustine and rituximab you shouldn’t take your capsules in the morning. You take them with you to the clinic and have them when told to.
You have up to 6 cycles of bendamustine and rituximab. You continue to have ibrutinib (or the dummy drug) as long as the treatment is helping you and the side effects aren’t too bad.
The researchers will ask for a number of blood samples on 2 occasions before your treatment starts. They will use these to find out how much of the drug is in your blood. You must agree to these blood samples if you want to take part in the trial.
They will also ask for a blood sample to look for a substance (
The trial team will ask you to fill out a questionnaire before you start treatment and then at regular times during the trial. The questionnaire will ask about side effects and how you’ve been feeling. This is called a quality of life study.
You see the doctor to have some tests before taking part in this trial. These tests include
During treatment you see the doctor regularly for a physical examination and blood tests. You have a CT scan every 3 months.
After treatment you see the doctor every 3 months for a physical examination, blood tests and bone marrow test. You have a CT scan every 3 months for 2 years and then every 6 months.
If your cancer gets worse you then see the doctor every 4 months.
The most common side effects of ibrutinib include
- Diarrhoea or constipation
- Tiredness (fatigue)
- Feeling or being sick (nausea)
- Skin rash
- Muscle aches and muscle cramps
- Loss of appetite
- Swelling of the hands and feet
- Joint aches
- Shortness of breath
- A drop in blood cells causing an increased risk of infection, bruising and bleeding
- Change to your heart rhythm
- Not enough fluids in your body (dehydration)
Your doctor will talk to you about the possible side effects before you agree to take part in the trial.
