A study looking at mogamulizumab and radiotherapy for people with T cell lymphoma of the skin (MOGAT)
Cancer type:
Status:
Phase:
This study is looking at an drug called mogamulizumab with
.
It is for people with a type of lymphoma that started in the of the skin (cutaneous T cell lymphoma) called mycosis fungoides.
It is for people who have had at least one type of treatment that reached the whole body (systemic), and their lymphoma has either:
• come back or
• got worse
More about this trial
Mycosis fungoides is a very slow growing (low grade) type of T cell lymphoma of the skin.
Doctors can use different treatments for mycosis fungoides. These include:
- light activated drug treatment such as psoralen ultraviolet light treatment (PUVA)
- radiotherapy – using x-rays to treat the mycosis fungoides
- interferon
chemotherapy
These treatments can work well to control mycosis fungoides, but for some people their lymphoma comes back or gets worse.
In this study, doctors are looking at a drug called mogamulizumab before and after radiotherapy to see if it helps people in this situation. Mogamulizumab is pronounced mo-gam-u-liz-oo-mab.
Mogamulizumab is a type of immunotherapy called a monoclonal antibody. It helps your immune system attack and destroy the lymphoma cells. Doctors use mogamulizumab without radiotherapy for mycosis fungoides at the moment.
Total skin electron beam therapy (TSEB) is a type of radiotherapy. It’s already a treatment for some people with mycosis fungoides. You can have it to treat larger areas of lymphoma that have not grown too deeply into the skin.
The aims of the trial are to find out:
- how well mogamulizumab and radiotherapy works for mycosis fungoides that has come back or got worse after treatment
- about the safety of mogamulizumab and radiotherapy
- about side effects of treatment
- about
quality of life
Who can enter
The following bullet points are a summary of 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.

You may be able to join this trial if all of the following apply. You:
- have either stage 1B, stage 2A or stage 2B mycosis fungoides when joining the trial
- have had at least 1 other treatment that reached your whole body (
systemic treatment ) and your mycosis fungoides has come back or got worse. You might be able to take part if you have had psoralen with ultraviolet light therapy (PUVA).
- might not be able to do heavy physical work, but can do anything else (performance status 0 or 1)
- have satisfactory blood test results

ECG and either an
ECHO (heart ultrasound) or
MUGA to check this
- have had at least 3 months break from your last dose of alemtuzumab (Campath) or similar drug, and your CD4+
T cells are above a certain level. Your doctor can explain more.
- are willing to use reliable contraception during treatment and for 6 months after the last dose if there is any possibility that you or your partner could become pregnant
- are at least 18 years old
Who can’t take part
Cancer related
You cannot join this trial if any of these apply. You:
- have had stage 3 or stage 4 mycosis fungoides now, or in the past
- have had mogamulizumab or a similar drug before. Your doctor can explain more.
- have had total skin electron beam therapy (TSEB) before
- have had any treatment that reaches your whole body for your lymphoma in the 4 weeks before joining the study. You might be able to take part if your lymphoma is growing quickly and you have had cancer treatment more recently than this. Your doctor can explain more.
- have any side effects from any other cancer treatment, apart from if they are very mild
- have had cancer in the past 5 years apart from very early stage (
in situ ) fully treated cervical cancer, prostate cancer that has not spread and you have a low amount of
PSA in your blood, early stage (in situ) melanoma or non melanoma skin cancer

stem cell transplant as part of your treatment
Medical conditions
You cannot join this trial if any of these apply. You:
- have had a serious infection in the 4 weeks before joining the study

- have had a heart attack in the last 6 months
- have
shingles when joining the study
- have an active
autoimmune disease apart from certain ones. The study team check this before you join the study.
- are taking medication to damp down your
immune system , which is not for your lymphoma, in the 7 days before joining the study. This includes high dose steroids that reach your whole body. You can still take part if you are taking low dose steroids, steroid injections into a joint, steroid eye drops, steroid inhalers or steroid nose drops.
- have HIV, HTLV-1, active hepatitis B or active hepatitis C
- have had an illness in the last 6 months which has been serious, getting worse or is uncontrolled. Your doctor can explain more.
- have a serious mental illness, or difficulties, that the team think would make it difficult for you to take part in the study
- have had a very severe reaction (anaphylaxis) to similar drugs to mogamulizumab, or anything that mogamulizumab contains
- are pregnant or breastfeeding
Trial design
This is a phase 2 study. Researchers hope that around 43 people from the UK and Europe will take part.
Everybody taking part has mogamulizumab and total skin electron beam therapy. This is whole body radiotherapy.
You have mogamulizumab as a drip into your bloodstream. You have mogamulizumab as This means you have the drug and then a rest to allow your body to recover. Each cycle is 28 days.
During cycle 1 you have mogamulizumab every week. During cycle 2 you have mogamulizumab every 2 weeks.
You then have a break from mogamulizumab for radiotherapy.
You have radiotherapy four times a week for 2 weeks. So, you have 8 radiotherapy sessions in total.
At least 2 weeks after your last radiotherapy session you start mogamulizumab again. This is cycle 3. You have mogamulizumab every week during cycle 3. For the rest of your cycles, you have mogamulizumab once every 2 weeks.
You have treatment for up to 18 months if it is working, and the side effects are manageable.
Research samples
You give blood samples during the study. The study team use these to learn more about how effect mycosis fungoides treatment.
Where possible, the samples for research are taken at the same time as your routine blood tests.
Extra samples for research
The researchers ask for:
- a blood sample at the start of the study, before and after radiotherapy and if your lymphoma gets worse
- a skin sample (skin
biopsy ) before the study, before radiotherapy and if your lymphoma gets worse. This is only if you have an area of mycosis fungoides they can take sample from.
- a mouth swab at the start of the study – this is to look at
DNA from the cells on the inside of your cheek
The study team would like to use these samples to learn more about mycosis fungoides, the study treatment and to try and help people in the future.
You don’t have to give these samples if you don’t want to. You can still take part in the study.
Quality of life
The study team will ask you to fill out questionnaire:
- before you start treatment
- at set times during treatment
- after you finish treatment
The questionnaires will ask about side effects and how you’ve been feeling. This is called a quality of life study.
Hospital visits
You see the trial doctor to have tests before you can take part. The tests include:
- a physical examination, including checking your pulse,
blood pressure and height and weight
- skin assessment – you might have photos of your skin taken
- blood tests
electrocardiogram MUGA or
ECHO - a
scan such as a CT scan, MRI scan or
PET-CT scan
You might also have:
- a urine test
- skin biopsy from your
lymph node
Cycle 1 and 2 of mogamulizumab
You go to the hospital either once a week or once every 2 weeks for your mogamulizumab drip. Each treatment takes about an hour. You see a member of the team for a blood test before your mogamulizumab and they see how you are getting on.
Before cycle 2 you have some tests, these include:
- a physical examination
- blood tests
- urine tests (if your team think you need one)
Radiotherapy
After your first two cycles of immunotherapy and before your radiotherapy starts you have tests. These are similar to the ones you have when you have mogamulizumab. You also have a skin assessment.
You might have some extra tests if your team think you need them. These are:
• a scan - such as an , CT scan or PET-CT scan
• a skin biopsy from a lymph node
Each radiotherapy treatment will last for 30 to 45 minutes. You see your radiotherapy doctor and have blood tests every week during radiotherapy. The radiotherapy team monitors your treatment closely.
Cycle 3 onwards
You usually have the same tests as you did for cycle 1 and 2. You have them at the start of each cycle and when you have your treatment.
Tests for lymphoma during treatment
Every 2 months you have a blood test to look for lymphoma.
Every 4 months you have a scan. And you might have a skin biopsy taken from your lymph node if your team thinks this is needed.
You see the team at week 48 and have:
- blood tests
- a scan
- a skin assessment
You can still see the study team if your lymphoma has got worse during treatment. Although you will not be able to have mogamulizumab as part of the study.
Follow up
Around 30 days after your last dose of mogamulizumab you go to the hospital for a follow up visit. The team see how you are getting on. You have some of the same tests you had during your treatment visits.
You see the study team for up to 30 months after you started the study treatment. They see how you are getting on and you have:
- a blood test and skin assessment every 2 months
- a scan with or without a skin biopsy every 4 months
Side effects
The study team monitor you during treatment and afterwards. Contact your advice line or tell your doctor or nurse if any side effects are bad or not getting better.
Mogamulizumab can affect the These side effects could happen during treatment or months after treatment has finished. Rarely, these side effects could be life threatening. Your doctor or nurse can explain what these side effects are, the risk of them happening and what to look out for. |
