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 BHQ880 for myeloma in people with poor kidney function
We know that this is an especially worrying time for people with cancer and their family and friends. We have separate information about coronavirus and cancer. Please read that information alongside this page. We will update that information as guidance changes.
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at a new drug called BHQ880 as first line treatment for myeloma. It is for people whose kidneys are not working very well.
Doctors can use treatments such as chemotherapy and stem cell transplants to treat myeloma. And you may have drugs called bisphosphonates to help prevent bone damage. But if your kidneys are not working very well, you cannot have some of these treatments.
In this trial, doctors are looking at a drug called BHQ880. It is a monoclonal antibody which blocks a protein called DKK1. DKK1 stops cells called osteoblasts from forming new bone. This often happens if you have myeloma and causes bone damage and pain. Blocking the DKK1 protein may allow the osteoblasts to start making new bone again.
We know from laboratory research that BHQ880 may also stop myeloma cells growing, but researchers don’t know if this will happen in people.
The aims of the trial are to
- See if BHQ880 can help people with myeloma
- Learn more about the side effects, what happens to the drug in your body and what effect it has on your bones
Who can enter
You may be able to enter this trial if you
- Have been diagnosed with myeloma and are over 55 (some younger people may be able to take part, but the trial team would need to assess each person on an individual basis)
- Cannot have a stem cell transplant
- Are well enough to carry out all your normal activities, apart from heavy physical work (performance status of 0 or 1)
- Have satisfactory blood test results
- Are willing to use reliable contraception during the trial and for 8 months afterwards if you are female and there is any chance you could become pregnant
You cannot enter this trial if you
- Have had any other treatment for myeloma apart from radiotherapy, surgery or
steroidsto treat symptoms, or 1 dose of bortezomib
- Have not fully recovered from surgery or side effects of radiotherapy
- Have had another cancer, apart from non melanoma skin cancer, carcinoma in situ of the cervix or superficial bladder cancer that has been treated, or any other cancer if it was successfully removed and there have been no signs of the disease coming back for at least 3 years
- Have ever had a bisphosphonate drug through a drip into a vein, or taken one by mouth in the last 4 months
- Have a high level of calcium in your blood that needs treatment other than steroids
- Have a condition called Paget’s disease of the bone
- Have over active
parathyroid glands(hyperparathyroidism) and this has not been treated
- Have damage to your nerves (
peripheral neuropathy), unless it is mild
- Have had an experimental drug as part of another clinical trial in the last 4 weeks
- Have a heart condition that is a cause for concern
- Have any other medical condition that the trial doctors think could affect the trial treatment
- Are known to be very sensitive to a substance called boron
- Are known to be HIV, hepatitis B or hepatitis C positive
- Are pregnant or breastfeeding
This phase 2 trial will recruit about 144 people in a number of different countries. The trial is in 2 parts.
The first part will recruit 6 to 8 people and all of them will have BHQ880.
You have treatment in 3 week periods called cycles of treatment. You have BHQ880 through a drip into a vein on the first day of each cycle. This takes about 2 hours each time. As long as you don’t have bad side effects, you can have up to 24 cycles of BHQ880.
During the first 9 cycles of treatment, you also have a drug called bortezomib and a steroid called dexamethasone. You have bortezomib as an injection into your vein on 4 days during each treatment cycle. You take dexamethasone tablets on 8 days during each cycle.
The second part of the trial will recruit about 136 people. This part is randomised. 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. And neither of you will know which group you are in either. This is called a double blind trial.
Half the people taking part have BHQ880, the other half have a dummy drug (
You have BHQ880 (or the dummy drug) in 3 week cycles as described for the first part of the trial. You have up to 24 treatment cycles. During the first 9 cycles, everybody also has bortezomib and dexamethasone.
You will see the doctors and have some tests before you start treatment. The tests include
- Physical examination
- Blood and urine tests
- An X-ray of your bones
- CT scan
- Bone density scan (
- Heart trace (
You may also have a bone marrow test.
You see the trial doctors every 3 weeks during treatment. People joining the first part of the trial will have some extra hospital visits in the 1st and 4th cycles of treatment to have more blood tests.
During treatment you have
- 2 more CT scans
- 3 more bone X-rays or MRI scans
- Another bone density scan (DXA scan)
You may also have another bone marrow test.
If you stop having treatment before the end of 24 cycles, you see the trial doctors a week later and have an X-ray, a CT scan, a DXA or MRI scan, blood and urine tests. If you finish all 24 cycles of treatment, you see the doctors and have these tests 4 weeks later.
The trial team will check how you are for up to 3 years after you finish treatment, but this may be by phone rather than having more hospital visits.
As BHQ880 is a new drug, there may be side effects we don’t know about yet. Possible side effects include
- A drop in the number of white blood cells causing an increased risk of infection
- A rise in your blood pressure
- Pain in your bones
- Muscle spasms
- Taste changes or loss of taste
- Hair thinning
The side effects of bortezomib include
- A drop in blood cells causing an increased risk of infection, bleeding problems, tiredness and breathlessness
- Feeling or being sick
- Numbness and tingling in your hands and feet (peripheral neuropathy)
- Nerve pain
- Loss of appetite
- Tiredness (fatigue)
- Cough or difficulty breathing
- Problems sleeping
- Build up of fluid in your arms or legs
