A trial of MK 8628 for acute myeloid leukaemia and diffuse large B cell lymphoma
Coronavirus and cancer
We know it’s a worrying time for people with cancer, we have information to help. If you have symptoms of cancer contact your doctor.
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at MK 8628 for people with acute myeloid leukaemia (AML) and diffuse large B cell lymphoma (DLBCL) who have had previous treatment. Some people over 60 years old may have treatment as part of the trial even if they haven’t had previous treatment for their leukaemia or lymphoma.
More about this trial
MK 8628 works by blocking a protein that cancer cells need to grow. We know from early research that MK 8628 might help people with blood cancers such as leukaemia and lymphoma.
In this trial researchers want to find:
- the best dose of MK8628 for people with AML or DLBCL
- how safe MK 8628 is for these people
- what the side effects are
- how well it works
Who can enter
The following bullet points list the entry conditions for this trial. Talk to your doctor or the trial team if you are unsure about any of these. They will be able to advise you.
You may be able to join this trial if you have acute myeloid leukaemia (AML) and are in one of the following situations:

allogeneic stem cell transplantthat was more than 3 months ago
- You have the
Philadelphia chromosomeand have had 2 types of treatment that included drugs such as imatinib, nilotinib and dasatinib or you had only 1 of these and your AML came back or continued to grow because of a change ( mutation) in the leukaemia cells that make them resistant to these type of drugs
You have diffuse large B cell lymphoma (DLBCL) and are in one of the following situations:

monoclonal antibodyor you are not able to have monoclonal antibodies
And all of the following apply. You:

- You have high blood pressure that isn’t controlled by medication
- You have any other medical or mental condition that the trial team think could affect you taking part in the trial
- You take any medication that affects body substances called CYP enzymes
- You are unable to swallow tablets or capsules
- You have already had a drug that works in the same way as MK8628
- You are pregnant or breastfeeding
This is a phase 1 trial. The researchers need 56 people to join.
The researchers are looking at 2 different doses of MK 8628. The first 6 people taking part will have a low dose of MK 8628. If they don’t have any serious side effects, the next few people will have a slightly higher dose.
MK 8628 is a capsule you take twice a day. You have a diary to write down the dose of MK 8628 you took and when.
You continue taking MK8628 as long as it is helping and the side effects aren’t too bad.
People who have AML have a bone marrow test done before starting treatment.
People who have DLBCL need to have a small piece of a lymph node taken (a
You have extra blood samples taken when you start treatment. The researchers will use these samples to see what happens to MK 8628 in the body. They will also use them to find out more about AML and DLBCL.
You see the doctor to have some tests before you take part in the trial. These tests include:
- a physical examination
- blood tests
- urine test
- heart trace (
- bone marrow test for people with AML
- lymph node biopsy for people with DLBCL if needed
- PET-CT scan and CT scan for people with DLBCL
During treatment you see the doctor every 3 weeks for a physical examination and blood tests.
People with AML have a bone marrow test every 3 weeks to week 15 and then every 3 months.
People with DLBCL have a PET-CT scan and CT scan every 3 months.
You see the doctor at the end of treatment and a month later for the same tests you had at the start.
People with AML then see the doctor every 6 weeks for a blood test and a bone marrow test if needed.
People with DLBCL then see the doctor every 3 months for a PET-CT scan and a CT scan.
You continue to see the doctor as part of the trial until your cancer starts to get worse or you start another treatment. Then your doctor will tell you how often they want to see you.
MK 8628 is a new drug and there might be side effects we don’t know about yet. You will be monitored during the time you are having the drug and you will have a telephone number to contact the hospital if you are concerned about anything. The most common side effects reported are:
- upset stomach
- a drop in blood cells causing an increased risk of infection, bruising, bleeding and shortness of breath
- loss of appetite and changes to taste
- feeling or being sick
- feeling weak and having no energy
- changes to the way your liver works
- itchy skin rash
Your doctor will talk to you about the side effects of MK 8628 before you agree to take part in the trial.
