A trial looking at durvalumab and tremelimumab for kidney cancer (RAMPART)

Cancer type:

Kidney cancer
Renal cell cancer




Phase 3

This trial is looking at durvalumab and tremelimumab after having surgery to remove kidney cancer.

More about this trial

To treat kidney cancer doctors can remove part of the kidney or the whole kidney. After surgery you have regular scans Open a glossary item and clinic appointments to check whether your cancer is coming back. This is active monitoring. 

Durvalumab and tremelimumab are both immunotherapies. They work by helping your immune system Open a glossary item attack cancer. 

In this trial some people:

  • are actively monitored and don’t have either of the drugs in the study
  • have durvalumab
  • have durvalumab and tremelimumab

The aim of this trial is to find out if durvalumab on its own or in combination with tremelimumab can stop or delay kidney cancer coming back.

Trial design

This is an international phase 3 trial. The trial team need 1,750 people worldwide to join with 1,175 people from the UK. 

It is a randomised trial. There are 3 treatment groups. Neither you nor your doctor can choose which group you go into. For every 7 people who join:

  • 3 people go into group A
  • 2 people go into group B
  • 2 people go into group C

The treatment groups are:

  • 750 people are actively monitored (group A)
  • 500 people having durvalumab (group B)
  • 500 people having durvalumab and tremelimumab (group C)

Group A
You won’t have treatment. But have regular CT scans and clinic appointments to see how you are going. 

Group B
You have durvalumab every 4 weeks for a year. You have durvalumab and tremelimumab as a drip into a vein

Both durvalumab and tremelimumab takes about an hour each to have. You have regular CT scans and clinic appointments to see how you are going.

Group C
You have durvalumab every 4 weeks for a year. On your 1st and 2nd treatment of durvalumab you also have tremelimumab. 

You then continue with durvalumab on its own for a year. You have regular CT scans and clinic appointments to see how you are going.

Research samples
The team ask for a small piece of the cancer tissue that was taken out when you had surgery. You also give a blood sample before you start treatment. The team use these samples to find out:

  • why some people have more side effects than others
  • how well the treatment is working
  • which people most likely benefit from having immunotherapy 

You must agree to give these samples to take part in the trial. 

Quality of life
You fill in 3 questionnaires:

  • when you join the trial
  • 3 times during the trial

The questions ask about:

  • your general heath
  • what you can do
  • any symptoms or side effects you have 

These are quality of life questionnaires

You don’t have to agree to do the questionnaires if you don’t want to. You can still take part in the trial.

Hospital visits

You see the doctor to have tests before taking part. These tests include:

  • a physical examination
  • blood tests
  • heart trace (ECG Open a glossary item)
  • CT scan

Group A
During the trial you see the doctor at weeks 16 and 32 for a blood test and CT scan.

You are then seen by the doctor:

  • every 3 months between year 1 and year 3
  • then every 6 months to year 5 
  • then every year

Groups B and C
During treatment you see the doctor every 4 weeks for blood tests and to see how you are. 

You are then seen by the doctor:

  • every 3 months between year 1 and year 3
  • then every 6 months to year 5
  • then every year

Everyone has a CT scan at:

  • 1 year
  • then every 6 months to 3 years
  • then at years 4, 5, 7 and 10 

Side effects

The trial 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.

Durvalumab and tremelimumab can affect the immune system. This might cause inflammation in different parts of the body which can cause serious side effects. It could happen during treatment, or some months after treatment has finished. Rarely, these side effects could be life threatening.

If you have any of these side effects, you should tell the doctor or nurse as soon as possible that you are on or have been on an immunotherapy.

The most common side effects of taking durvalumab and tremelimumab include:

There is a small chance you might have an allergic reaction to durvalumab or tremelimumab. This could happen hours or days after having treatment. Contact your doctor or the advice line if you have any of the following symptoms:

  • swelling of the face or tongue
  • trouble breathing or swallowing

We have more information about durvalumab.

Your doctor or a member of the trial team will talk about the possible side effects of treatment before you agree to take part.
