A study of INCB050465 for a type of non-Hodgkin lymphoma called marginal zone lymphoma (CITADEL 204)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
Cancer type:
Blood cancers
Low grade lymphoma
Lymphoma
Non-Hodgkin lymphoma
Status:
Closed
Phase:
Phase 2
This study is looking at INCB050465 for marginal zone lymphoma that has come back or treatment has stopped working.
More about this trial
Certain types of non-Hodgkin lymphoma are slow growing. They are called low grade or indolent lymphoma. This study is for people with a type of low grade lymphoma called marginal zone lymphoma.
One of the usual treatments for marginal zone lymphoma includes a targeted drug called rituximab, or a combination of chemotherapy and rituximab. You might also have other types of targeted drugs such as ibrutinib if your lymphoma comes back or treatment stops working.
Doctors are looking for ways to improve treatment for marginal zone lymphoma. In this study, they are looking at a new drug called INCB050465.
INCB050465 is a type of targeted drug called a cancer growth blocker. It stops signals that cancer cells use to divide and grow.
The aims of the study are to:
- find out how well treatment works
- learn more about the side effects
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.

- have a long term or active infection and you need treatment to the whole body
- are going to have a live vaccination within 30 days of starting study treatment
- have HIV
- can’t swallow medication or absorb it, you have had part or all of your stomach removed, or you have a blockage in your bowel
- have any other serious medical condition or mental health problem that the study team think would affect you taking part
Other
You:

- are pregnant or breastfeeding
Trial design
This is a phase 2 study. The researchers hope about 120 people will take part.
Everyone has INCB050465. It is a tablet. There 2 different groups as the study team are testing 2 doses of INCB050465. The group you are put into depends on previous treatment you’ve had.
Group A
You have INCB050465:
- once a day for 8 weeks
- and then once a week at the same dose for the rest of the study
Group B
You have INCB050465:
- once a day for 8 weeks
- and then once a week at a lower dose for the rest of the study
You have treatment for as long as it is working, and the side effects aren’t too bad.
Samples for research
The researchers will ask for samples of your cancer that doctors took when you had a previous biopsy.
You also give some extra blood samples. Where possible, you have these at the same time as your routine blood tests.
The researchers plan to look at:
- gene changes (mutations)
- substances called biomarkers to help work out why treatment might work for some people and not for others
They might also ask you to:
- give more tissue samples
- give a sample of poo to check for side effects that affect the bowel
You don’t have to give these samples if you don’t want to. You can still take part in the study.
The researchers will ask to keep any leftover samples for future research.
Quality of life
The study 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 quality of life study.
Hospital visits
You see a doctor and have some tests before you can take part in the study. The tests include:
You might also have a bone marrow test or give a new tissue sample from an affected lymph node.
You go to the hospital once a month to see the study team for a check up. You have a CT scan every:
- 2 months for 6 months
- and then every 3 months
You go to hospital for a check up a month after you finish treatment.
Follow up
When you finish treatment, the study team will follow you up every 3 months for up to 2 years to see how you are getting on.
Side effects
As INCB050465 is a new drug, there may be 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:
- feeling or being sick
- diarrhoea
- tiredness (fatigue)
- cough
- an increased risk of infection
- skin rash
- dizziness
- low levels of a mineral in the body called potassium
INCB050465 can make your skin more sensitive to the sun. The study team recommend that you apply sunscreen, cover up and avoid long periods out in the sun.
You are also at risk of developing pneumonia if you take INCB050465. The study team will give you medication to reduce this risk. You take it when you start having INCB050465 and for 2 to 6 months after stopping. The study team can tell you more about this.
The study doctors will explain all the possible side effects before you join the study.
