"I am glad that taking part in a trial might help others on their own cancer journey.”
A trial looking at venetoclax for acute myeloid leukaemia
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
More about this trial
The main treatment to get rid of AML is intensive chemotherapy. This is a combination of:
anthracyclinechemotherapy drug such as daunorubicin
If you aren’t fit enough to have intensive chemotherapy your doctor might give you low dose cytarabine.
Venetoclax is a targeted drug. It works by blocking a protein found in AML cells. This causes the AML cells to die. From previous research we know that venetoclax might help people with AML.
The team want to find out if combining venetoclax with low dose cytarabine can help people who can’t have intensive chemotherapy.
In this trial, 2 out of every 3 people taking part have venetoclax and low dose cytarabine. And 1 out of every 3 people taking part have a dummy drug (
The main aims of this trial are to find out:
- how well venetoclax with low dose cytarabine works for people with AML who can’t have intensive chemotherapy
- what the side effects are
- how this combination affects your
quality of life
Who can enter
The following bullet points list the entry conditions for this trial. Talk to your doctor or the trial team if you are unsure about any of these. They will be able to advise you.
You may be able to join this trial if all of the following apply:
- you have acute myeloid leukaemia and can’t have intensive induction chemotherapy
- your kidneys work well enough, your doctor will do a test for this
- you have satisfactory blood test results
- you are willing to use reliable contraception during the trial and for at least 6 months afterwards if there is any chance you or your partner could become pregnant
- you are at least 18 years old
One of the following must also apply. You:

You cannot join this trial if any of these apply.
- have already had treatment for AML apart from hydroxyurea (hydroxycarbamide). You might be able to join the trial if you have had treatment for a
myelodysplastic syndrome(MDS) unless it included cytarabine
- had a
myeloproliferative neoplasm(MPN) before AML
- have acute promyelocytic leukaemia (APL)
- have AML that has spread to your brain or spinal cord
- have had another cancer apart from
carcinoma in situof the cervix or breast, non melanoma skin canceror any other cancer that hadn’t spread and had been treated with the aim to cure
- have HIV
- have hepatitis B or hepatitis C, you might be able to join if you are a carrier of hepatitis and it isn’t active or it is controlled by medication
- are taking medication that affects the CYP enzymes
- have moderate to severe heart problems that affects your daily activities
- have an ongoing breathing problem that means you need to have continuous oxygen
- have or have had serious problems with your kidneys
- have a problem with your
digestive systemthat affects how your body absorbs food and medications
- have an infection that affects your whole body and needs treatment
- have a high number of
white blood cellsin your blood, you might be able to join the trial if you are able to have hydroxyurea or a procedure called leukapheresis to bring the number of white cells in your blood down
- have any other medical or mental health problem that your doctor thinks could affect you taking part in the trial
- have eaten grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges) or star fruit within 3 days of starting treatment in the trial
- are pregnant or breastfeeding
This is an international phase 3 trial. The researchers need 175 people worldwide to join including up to 6 people from the UK.
This is a randomised trial. You are put into 1 of 2 treatment groups and neither you nor your doctor can choose which group you are in.
- venetoclax and low dose cytarabine
- dummy drug (
placebo) and low dose cytarabine
You have twice as much chance of going into the venetoclax group than the dummy drug group.
Neither you nor your doctor will know which group you are in. This is a double blind trial.
Venetoclax and the dummy drug are tablets. You take them within 30 minutes of finishing breakfast or your first meal of the day.
You take increasing doses of venetoclax, or the dummy drug, until you are taking the maximum dose. This can take about 5 days. You stay in hospital during this time so the nurses can monitor you.
You have the low dose cytarabine as an injection under the skin. You have it for 10 days every 4 weeks.
You usually come into the hospital each day to have the cytarabine. Or your doctor might be able to arrange for you to have it at home or at your local GP surgery, if possible. They will talk to you about this.
You continue having treatment for as long as it is helping and the side effects aren’t too bad.
You have a diary to fill in. You write down when you had your tablets and how many. You bring this with to every appointment.
The team will take extra blood samples, tissue samples and bone marrow samples.
The team will also ask if they can take blood samples to look at the
They will use these samples to find:
- why some people’s leukaemia responds better to treatment than others
- more about AML and how to treat it
- what happens to venetoclax in the body
Quality of life
You fill in a few questionnaires:
- at the start of treatment
- every 8 weeks while on treatment
- at the end of treatment
The questions ask about how you are feeling and any side effects you might have. This is a quality of life study.
You see the doctor to have some tests before joining the trial. These include:
- a physical examination
- blood tests
- urine test
- breathing test (
lung function test)
- heart scan (
- heart trace (
- bone marrow test
You are in hospital for at least 5 days at the start of treatment. When you leave hospital, you see the doctor or nurse at least once a week for 3 weeks. This is to have blood tests to see how you are.
During treatment you see the doctor every 4 weeks for blood tests and a physical examination. You have a bone marrow test at 4 weeks and then every 12 weeks.
At the end of treatment you see the doctor for the same tests you had at the start. You see them a month afterwards and then every 2 months.
You are monitored closely for any side effects that might happen. The common side effects of venetoclax might include:
- infection of the nose and throat causing a runny nose and, or a cough
- a drop of white blood cells in the blood. You might have a high temperature (fever) as well, this is called febrile neutropenia
- diarrhoea or constipation
- feeling or being sick
- a lung infection (pneumonia)
- urine infection
- a high amount of phosphorous, uric acid, potassium, calcium and creatinine in the blood
When you first start treatment you might have tumour lysis syndrome. This is caused by the breakdown of the cells of the leukaemia. Your doctor might ask you to drink plenty of water before starting treatment. They might also give you some medication to take that will help your body get rid of this cell breakdown.
Signs of tumour lysis syndrome include:
- high temperature (fever)
- feeling or being sick
- shortness of breath
- irregular heartbeat
- unusual tiredness
- muscle pain
- sore joints
- fits (seizures)
You must tell your nurse or doctor straight away if you have any of these signs. You are in hospital for at least 5 days when start treatment so the nurses and doctor can monitor you.
We have information about the side effects of cytarabine.
