Last year in the UK over 60,000 cancer patients enrolled on clinical trials aimed at improving cancer treatments and making them available to all.
A trial of azacitidine with or without vorinostat for acute myeloid leukaemia or high risk myelodysplastic syndrome (RAvVA)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at azacitidine and vorinostat for people who can’t have intensive treatment for acute myeloid leukaemia (AML) or high risk myelodysplastic syndrome (MDS).
Doctors usually treat AML or high risk MDS with chemotherapy. But this treatment can be intensive. Some people can’t have intensive chemotherapy. You may have less intensive chemotherapy, but there is no
In this trial, researchers are looking at 2 drugs called azacitidine and vorinostat.
Azacitidine is a chemotherapy drug that doctors already use to treat AML in people who cannot have intensive chemotherapy.
The aim of the trial is to see if a combination of azacitidine and vorinostat is better than azacitidine alone for people who can’t have intensive chemotherapy for AML or MDS.
Who can enter
You may be able to enter this trial if
- You have acute myeloid leukaemia or myelodysplastic syndrome (MDS) that is considered to be high risk - you may have just been diagnosed, or you may have already had treatment but your disease didn't respond well or has come back
- You can’t have intensive treatment (your doctor will discuss this with you)
- You have satisfactory blood test results and are well enough to be up and about for at least half the day (performance status 0, 1 or 2)
- You are willing to use reliable contraception during the trial and for 3 months afterwards, if there is any chance you or your partner could become pregnant
You cannot enter this trial if you
- Have a type of AML called acute promyelocytic leukaemia
- Have chronic myeloid leukaemia (CML) that has become acute (blast phase)
- Have any other type of cancer
- Have had a stem cell transplant
- Have already had azacitidine or similar drugs such as decitabine
- Have had any other drug that is classed as a histone deacetylase inhibitor if it was used as an anti cancer treatment (your doctor can confirm this)
- Have had any other cancer treatment, including experimental drugs in the last 30 days
- Have certain heart problems – the trial doctors can advise you about this
- Can’t have either of the study drugs for some reason, or are not able to have injections under the skin (subcutaneous injections)
- Have any serious infection or other medical condition that the trial doctors think could affect you taking part
- Are pregnant or breastfeeding
This phase 2 trial will recruit about 260 people. 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.
People in one group have azacitidine and vorinostat, people in the other group have azacitidine alone.
Everybody has 4 week cycles of treatment.
You have azacitidine as an injection just under your skin (subcutaneous injections) once a day for 7 days at the beginning of each treatment cycle.
Vorinostat is in capsules that you swallow. If you are in the group having vorinostat, you take the capsules on 7 days in each cycle of treatment, starting on the 3rd day.
You have 6 cycles of treatment. But if it is helping and you don’t have any bad side effects, the trial doctors will talk to you about having the treatment for longer.
The trial team will ask you to fill out a questionnaire before you start treatment, at the beginning of each treatment cycle and when you finish treatment. The questionnaires ask about side effects and how you’ve been feeling. This is called a quality of life study.
You will see the doctors and have some tests before you start treatment. The tests include
- Blood tests and urine tests
- Physical examination
- Heart trace (
- Bone marrow test
You go to hospital to have the azacitidine injections. This means you go to hospital on at least 7 days in each 4 week cycle. Each visit lasts up to 3 hours, but you don’t stay in overnight.
You have regular blood tests and more bone marrow tests at the end of the 1st, 3rd and 6th cycles of treatment.
If you carry on having treatment after 6 cycles, you will continue to have regular blood tests and a bone marrow test every 3 months.
When you finish treatment, you continue to have blood tests once a month for 2 years.
The trial team will talk to you about all possible side effects before you agree to join the trial.
The side effects of azacitidine include
- Feeling or being sick
- Diarrhoea or constipation
- A drop in blood cells causing an increased risk of infection, bleeding problems, tiredness and breathlessness

- High temperature (fever)
- Loss of appetite
- Tiredness (fatigue)
- Breathing difficulties, shortness of breath and chest pain

- Cough or upper respiratory tract infection
- A drop in blood cells, causing an increased risk of infection, bleeding problems, tiredness and breathlessness
