"I was delighted to take part in a clinical trial as it has the potential to really help others in the future.”
A trial looking at pomalidomide, bortezomib and dexamethasone for myeloma
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is for people whose myeloma has stopped responding to treatment or has come back.
More about this trial
Doctors are always looking for ways to improve treatment for people with myeloma. In this trial, they are looking at giving pomalidomide with bortezomib and dexamethasone. Pomalidomide affects how your immune system works. It is a type of drug called an immunomodulatory agent.
Bortezomib and low dose dexamethasone (a steroid) are 2 drugs that doctors already use to treat myeloma.
Some people in this trial have pomalidomide, bortezomib and low dose dexamethasone. And some people have bortezomib and low dose dexamethasone.
The aims of the trial are to
- Find out which treatment works best
- Learn more about the side effects
- Find out how treatment affects quality of life

- You have had major surgery, a procedure called plasma exchange, radiotherapy or any treatment for your myeloma in the last 2 weeks
- You have an
autoimmune conditionsuch as rheumatoid arthritis, multiple sclerosis or lupus and you need to take a regular high dose of a steroid or other treatment to manage your condition

This is phase 3 trial. The trial team need 544 people to join.
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.
- One group will take pomalidomide, bortezomib and low dose dexamethasone
- The other group will take bortezomib and low dose dexamethasone
You will have treatment in 3 week cycles (21 days). In each 3 week period you will have
- Bortezomib injections under your skin (subcutaneous injections) on 2 days a week for the first 2 weeks of each treatment cycle
- Dexamethasone tablets on 4 days a week for the first 2 weeks of each cycle
- Pomalidomide is a tablet. If you are taking these you will take them every day for the first 2 weeks of each treatment cycle
You will start by having 8 treatment cycles. After that, you will have treatment less frequently in each cycle. But the trial team can tell you more when you reach this stage of treatment.
As long as you don’t have bad side effects, you can carry on having the treatment for as long as it helps you.
Samples for research
If you are in the pomalidomide group, the researchers may ask to take extra blood tests as part of this trial. Where possible you have these at the same time as your routine blood tests. The researchers want to find out what happens to pomalidomide in the body (
The researchers may also ask to take an extra bone marrow biopsy of your myeloma at the beginning and end of treatment. They will look for biomarkers and they may use it for other tests in the future.
If you don’t want to give these samples for research, you don’t have to. You can still take part in the trial.
Quality of life questionnaires
The trial team will ask you to fill out a questionnaire before you start treatment and at set times during treatment. The questionnaire will ask about side effects and how you’ve been feeling. This is called a
You see the trial team and have some tests before you start treatment. The tests include
- Physical examination
- Blood tests
- Urine tests
- A heart trace (
- Bone marrow test
- X- rays of your long bones, spine, the area between your hip bones (pelvis) and skull (skeletal survey)
During the first 8 cycles of treatment, you go to hospital at least 4 times in each 3 week period for treatment and a check up.
If you stop treatment but your myeloma hasn’t got worse, the trial team will follow you up every 3 weeks.
If your myeloma gets worse, you stop having treatment. You see the trial team every 3 month for 5 years. This may be at a routine hospital appointment or they may phone you.
The most common side effects of pomalidomide include
- A drop in blood cells causing an increased risk of infection, bleeding problems, tiredness and breathlessness
- Constipation or diarrhoea
