A study of blinatumomab for B cell non Hodgkin lymphoma
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This study is for people who have fast growing lymphoma that has come back or is no longer responding to treatment.
More about this trial
Rituximab and chemotherapy are the usual treatments for B cell non Hodgkin lymphoma that is fast growing (high grade). Unfortunately, treatment can stop working or the lymphoma can come back. Doctors might treat it with rituximab and chemotherapy again, followed by a
Doctors know that if you have had rituximab in the past, it doesn’t always work as well the second time. So they are looking at new treatments.
In this study, they are looking at a drug called blinatumomab. It is a targeted cancer drug (
Blinatumomab seeks out particular proteins on the surface of cells. One part binds to the surface of a cancer cell. The other part binds to the surface of a white blood cell. This helps the white blood cells to find and kill the cancer cells.
Researchers want to see if it helps to get rid of all signs of the lymphoma before going on to have a stem cell transplant. This is called having a complete molecular response. You have a
This study is in 2 parts. Part 1 is looking at blinatumomab followed by a stem cell transplant. Part 2 is comparing blinatumomab with
The aims of this study are to find out:
- how well blinatumomab works
- how safe it is
- if blinatumomab is better than rituximab and chemotherapy for people having rituximab a second time
- more about the side effects
- more about
quality of life
Who can enter
The following bullet points list the entry conditions for this study. Talk to your doctor or the study team if you are unsure about any of these. They will be able to advise you.
You might be able to join this study if all of the following apply. You
- Have a fast growing (high grade) B cell non Hodgkin lymphoma such as diffuse B cell lymphoma or follicular lymphoma that was grade 3b at diagnosis
- Had rituximab and chemotherapy as your first treatment and it stopped working or the lymphoma came back
- Have had at least 2 cycles of the usual treatment given before a stem cell transplant that included a
platinum chemotherapydrug such as cisplatin or carboplatin and your lymphoma got worse, stayed the same or went away a little bit or you had 1 cycle and your lymphoma got worse
- Have an area of lymphoma that can be seen on a scan and measures at least 1.5cm across or you have an area of lymphoma outside the
lymph glandsthat measures at least 1cm across
- Have had a recent sample of tissue (
biopsy)taken of your lymph nodes which showed your lymphoma has come back
- Are suitable to have high dose chemotherapy and a stem cell transplant
- Are well enough to be up and about for at least half the day (performance status 0,1 or 2)
- Are willing to use reliable contraception during treatment and for up to 48 hours after the last dose of blinatumomab
- Have satisfactory blood test results
- Are at least 18 years old
You cannot join this study if any of these apply. You
- Have a type of non Hodgkin lymphoma called lymphoblastic lymphoma or Burkitt’s lymphoma
- Didn’t have any signs of your lymphoma after rituximab and chemotherapy (you had a complete molecular response)
- Have had high dose chemotherapy and a stem cell transplant in the past
- Have had a stem cell transplant with your own cells in the past
- Have lymphoma in your brain or spinal cord (central nervous system)
- Have had any other cancer in the last 3 years apart from very early cancers that were successfully treated
- Have had blinatumomab or a similar type of drug in the past
- Have had treatment as part of a clinical trial within 30 days of joining this study
- Have had a serious condition that affects your brain such as epilepsy, seizures (fits), a stroke or a severe brain injury
- Have hepatitis B or hepatitis C
- Have HIV
- Have any other serious medical condition or mental health problem that the study team think could affect you taking part
- Are allergic to blinatumomab, immunoglobulins or anything they contain
- Are pregnant or breastfeeding
This phase 2/3 study is taking place worldwide.
The study is in 2 parts. The researchers need 36 people to join part 1 and 296 people to join part 2. The study will include about 4 people in total from the UK.
In part 1, everyone has blinatumomab and a stem cell transplant. When enough people have joined part 1, then part 2 will begin.
Part 2 is randomised. You are put into 1 of 2 groups. You have 1 of the following:
- blinatumomab followed by a stem cell transplant
- rituximab and chemotherapy followed by a stem cell transplant
Neither you nor your doctor will be able to decide which group you are in.
You have blinatumomab over 8 weeks followed by 2 to 4 weeks without treatment. This 12 week period is 1 cycle of treatment. You have 1 cycle to begin with.
You have blinatumomab through a
If the treatment helps, you might have a 2nd blinatumomab treatment. The study team can tell you more if this applies.
Chemotherapy and rituximab
In the standard treatment group, you have chemotherapy and rituximab. For example, you might have a treatment called R-CHOP. This includes the drugs:
You have treatment in cycles. Each 2 or 3 week period is called a cycle of treatment. You have 6 cycles over 21 weeks. The study team can give you more information about the drugs you are have and how often you have them.
For both treatments, if it helps to get rid of the lymphoma, then you might be able to have a stem cell transplant.
Samples for research
As part of the study, the doctors will ask for some extra blood samples. Where possible, you have these at the same time as your routine blood tests.
They plan to look at:
- what happens to blinatumomab in the body (
- substances called
biomarkersto help work out why treatment might work for some people and not for others
They might use the samples for future research studies.
The doctors are also looking at pharmacogenetic testing looking at your genetic material (DNA), in your body cells such as blood and tissue cells. Knowing more about people’s genetic material might help the doctors to understand why lymphoma can behave differently in different people and how their bodies respond to treatment.
They will ask to use blood samples and any tissue samples you have taken during the study. You would not need to have any extra samples taken.
You don’t have to agree to this genetic testing if you don’t want to. You can still take part in the study.
You see a doctor and have some tests before you can take part. These include:
- physical examination
- blood tests
- heart trace (
- PET-CT scan
You might also have a bone marrow test.
You stay overnight in hospital for the first 3 days of blinatumomab. You might have to go back to hospital for a short stay if the doctors need to change the dose. Otherwise you continue having the treatment at home. You go to hospital once or twice a week for check ups.
You have your chemotherapy and rituximab in the hospital day unit. You shouldn’t need to stay overnight.
You have a PET-CT scan at the end of blinatumomab treatment. If you are having rituximab and chemotherapy you have PET scan at the end of cycle 3 and 6.
You have a check up:
- 1 month after you finish treatment
- every 3 months for 2 years
After that, the study team will contact you at home every 6 months for 2 years to see how you are getting on.
Blinatumomab is a new drug for B cell NHL, so there might be some side effects we don’t know about yet. The study team will monitor you during the time you have treatment and you’ll have a phone number to call them if you are worried about anything.
So far the most common side effects include:
- a drop in the number of blood cells causing an increased risk of infection, bleeding problems, tiredness and breathlessness
- tummy pain
- diarrhoea or constipation
- tiredness (fatigue)
- chest pain
- bone, joint or back pain
- pain in the arms, legs and hands
- problems falling asleep or staying asleep
- weight gain
- swelling of hands, legs, ankles, feet or face
- high levels of sugar (glucose) in the blood
- low levels of magnesium or potassium in the blood
There is a small chance that you might have a mild reaction to blinatumomab. This can cause:
- low blood pressure
- feeling and being sick
There is also a small chance that blinatumomab can cause central nervous system problems such as:
- seizures (fits)
- memory loss
Your doctor will keep a close eye on you and treat these straight away. They will explain all the possible side effects before you join the study.
