A trial looking at decitabine for myelodysplastic syndrome and acute myeloid leukaemia (DEC-MDS)
This trial is for people with myelodysplastic syndrome (MDS) and also for people with acute myeloid leukaemia (AML) who have between 2 and 3 out of 10 blood cells (20 to 30%) that are immature.
Myelodysplastic syndrome (MDS) is a condition affecting the bone marrow. 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). If you have a lot of abnormal cells in your bone marrow, there is a higher risk of the MDS becoming AML. Doctors may call this high risk MDS.
Doctors often treat high risk MDS with blood transfusions and antibiotics. This helps control the symptoms and fight infections that people with MDS might get. Doctors may call this ‘Best Supportive Care’ because it only improves the quality of life of people with MDS but does not treat their disease.
The researchers hope that a new drug called decitabine may be able to help treat people with high risk MDS and AML.
The aims of this trial are to find out
- How well decitabine works for people with MDS and AML
- The side effects of giving decitabine to people with MDS and AML
Recruitment
Phase
Who can enter
You can enter this trial if you have
- Myelodysplastic syndrome (MDS) with 1 in 20 (5%) or more of your blood cells being immature (blasts) and an average to high risk of the MDS becoming leukaemia – your doctor can advise you about this
- Acute myeloid leukaemia (AML) with between 2 and 3 out of 10 of your blood cells (20 to 30%) being immature – your doctor will be able to explain this
- A rare condition called chronic myelomonocytic leukaemia type 2 (CMML-2)
And also you
- Have had azacitidine and your disease continued to grow, or come back, during treatment or come back in the 3 months after treatment or you stopped treatment due to bad side effects
- Have satisfactory blood test results
- Are well enough to be up and about for at least half the day (performance status 0, 1, 2)
- Are willing to use reliable contraception while having treatment, and for 2 months after, if there is a chance that you or your partner could become pregnant
- Are at least 18 years old
You cannot enter this trial if you
- Have had decitabine before
- Have had intensive combination chemotherapy to treat your MDS or AML before
- Have had high dose cytarabine chemotherapy to treat your MDS or AML before
- Have had a drug as part of another clinical trial in the last 30 days
- Are taking steroid tablets (you should not stop taking your steroids without talking to your doctor)
- Have another cancer
- Have an infection
- Are HIV positive
- Have another medical condition that could affect you taking part in the trial
- Are pregnant or breastfeeding
Trial design
This is a phase 2 trial. It will recruit about 50 people. Everyone will have decitabine chemotherapy.
You have decitabine through a drip into a vein over 60 minutes. You have 5 days of decitabine every 28 days. Each 28 day period is called a cycle of treatment.
You continue to have decitabine as long as the side effects are not too bad and it is still helping you.
Hospital visits
You see the doctor and have some tests before taking part in this trial. These tests include
- A physical examination
- Blood tests
- Bone marrow test
- Pregnancy test (if appropriate)
You have a blood test every week for the first 6 months.
You see the doctor every 4 weeks and have the following
- A physical examination
- Blood tests
- Pregnancy test (if appropriate)
You have a bone marrow test at 3 and 6 months. If you need more bone marrow tests than this, your doctor will discuss this with you.
You see the doctor a month after stopping treatment and have the following
- A physical examination
- Blood tests
You then see the doctor every 3 months for a year.
Side effects
The side effects of decitabine may include
- A drop in the number of blood cells causing an increased risk of infection, bruising or bleeding problems
- Tiredness
- Feeling, or being, sick
- Diarrhoea
- Aches
- Changes to the way your liver works
- Changes to the way your kidneys work
