Around 1 in 5 people diagnosed with cancer in the UK take part in a clinical trial.
A trial looking at CHR-3996 and tosedostat for myeloma (MUK three)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at 2 new drugs, CHR-3996 and tosedostat (pronounced toe-sed-oh-stat) for people with myeloma that has come back or did not go away following treatment.
More about this trial
Myeloma that has come back or did not go away following treatment can be more difficult to treat.
Tosedostat also stops signals that cancer cells use to divide and grow. Doctors want to find out if combining CHR-3996 and tosedostat will help people with myeloma.
The aims of this trial are to find out
- If CHR-3996 alone causes side effects
- The best dose of CHR-3996 and tosedostat to give
- About the side effects
- If these new drugs help people with myeloma that has come back or did not go away following treatment
Who can enter

This trial will recruit up to 66 patients from the UK.
CHR-3996 and tosedostat are tablets. You take them daily until your cancer starts to grow again or you do not want to take them anymore. The dose and combination of drugs you have depends on when you join the trial.
The trial is in 2 parts.
In the first part of the trial a few patients have CHR-3996 alone. If they do not have any serious side effects the next patients have CHR-3996 and tosedostat together and have the lowest dose.
If they don’t have any serious
In the second part of the study patients have the best dose of CHR-3996 and tosedostat found in the earlier part of the study. If you were previously treated at a lower dose you may be able to change to the ‘best dose’. Your doctor will explain.
You will see the doctors and have some tests before you start treatment. The tests include
- Blood tests
- Physical examination
- Heart trace (
- Bone marrow test (if needed)
- Urine tests (if needed)
If you need bone marrow tests or urine tests your doctor will discuss these with you.
Everybody will see the doctor, have blood tests and heart trace tests frequently during the first 8 weeks of the trial. After 8 weeks you see the doctors and have these tests less often.
When you stop treatment you see the doctors, have blood tests and a heart trace. The doctors then see you regularly until your cancer starts to grow again.
As CHR-3996 and tosedostat are new drugs, there may be side effects we don't know about yet. Possible side effects of CHR-3996 include
- Feeling or being sick
- Tiredness (fatigue)
- Weight loss
- A drop in platelets
- A rash
- Taste changes
Possible side effects of tosedostat include
