A trial looking at durvalumab for people with non small cell lung cancer after surgery (MERMAID-2)

Please note - this trial is no longer recruiting patients. We hope to add results when they are available.

Cancer type:

Lung cancer
Non small cell lung cancer

Status:

Closed

Phase:

Phase 3

This trial is for people with non small cell lung cancer (NSCLC) who:

  • have had surgery to completely remove their cancer
  • have no sign of cancer on tests and scans after surgery

It is for people who have stage 2 NSCLC, and some people with stage 3 disease.

This trial also looking at measuring small amounts of cancer cells that may be in the bloodstream after surgery. Depending on the results, you may have treatment as part of this trial.

More about this trial

Surgery is a common treatment for stage 2 NSCLC. It is also a treatment option for some people with stage 3 NSCLC.

Some people with NSCLC have a greater risk of their cancer coming back even if:

  • surgery was successful
  • they had extra cancer treatment before or after surgery

In this situation, doctors usually monitor you with scans to check that there are no signs of cancer. This is called ‘watch and wait’. 

Doctors want to improve on ‘watch and wait’. They would like to have a way of finding out whose cancer is more likely to come back. 

To do this, they are looking for people with small amounts of cancer DNA Open a glossary item  in their blood. This is called circulating tumour DNA Open a glossary item or ctDNA. This could show minimal residual disease (MRD). MRD means that even after successful treatment, there are still some cancer cells releasing DNA into the bloodstream. Because of this, the risk of lung cancer coming back might be higher.
 
The trial team also want to find out if people in this situation should have treatment with a drug called durvalumab

Durvalumab is a type of immunotherapy Open a glossary item. It stimulates the body's immune system Open a glossary item to fight cancer cells.

Everyone taking part in this trial enters the first surveillance (monitoring for MRD) part of the trial. If MRD is found, this means you are MRD positive.

If you are MRD positive, you have more tests and scans (second screening). You might then go on to have durvalumab or a dummy drug (placebo Open a glossary item).

If no MRD is found, you are MRD negative and have no treatment on the trial.

The main aims of the trial are:

  • to learn more about the safety of durvalumab
  • to get information about possible side effects of durvalumab
  • to see if having durvalumab reduces the risk of cancer coming back
  • to learn more about NSCLC and measuring MRD
  • to find out more about the quality of life Open a glossary item of people taking part

Who can enter

The following bullet points are a summary of the entry conditions for the first surveillance part of this trial.

Trial design

This is an international phase 3 trial. The researchers hope that around 1,500 people worldwide will take part. This includes 6 people from the UK having treatment as part of the trial.

First screening and start of surveillance
Everyone taking part has an individual MRD test made for them. To do this, the researchers compare genetic Open a glossary item information in your blood with your cancer tissue sample. This helps them see the difference between your normal blood cells and cancer cells. The team can use this information throughout the trial to see if there are any cancer cells in your blood (MRD).

If you are MRD negative, you are monitored on the trial for nearly 2 years to see if you become MRD positive.

You move onto the second screening part if you are MRD positive:

  • at the start of the trial
  • at any point during surveillance

Second screening
You have some more tests and scans to see if you are suitable to join the treatment part of the trial. If you are suitable, you move into treatment.

Treatment
This part of the trial is randomised Open a glossary item. Everyone taking part is put into 1 of the following groups by computer:

  • durvalumab (group 1)
  • dummy drug (group 2)

Neither you nor your doctor can choose which group you are in. And neither you nor your doctor will know which drug you are having. This is a double blind trial. 

You have durvalumab or dummy drug as a drip into your bloodstream (intravenously) every 4 weeks. It takes about 60 minutes to have treatment each time. You continue to have treatment for as long as it is helping you and the side effects aren’t too bad. You can have treatment for up to 2 years.

Follow up
After 2 years, you stop durvalumab or the dummy drug and have regular check ups with your trial doctor until the end of the study.

Quality of life (second screening onwards)
Everyone taking part completes quality of life questionnaires at the time of your second screening and then:

  • every 4 weeks for 2 years
  • every 4 weeks during follow up – until the end of the study or until your cancer comes back

The questionnaires ask about how you have been feeling and what side effects you have had.

Blood samples 
You have blood tests as part of this trial. You have them before the start of treatment and at set times during this trial. Researchers want to:

  • find out what happens to durvalumab in your body 
  • look at the cancer DNA
  • look for certain proteins (biomarkers Open a glossary item) that can help to tell why some treatments work better than others

Tissue sample
The trial team will ask to use a recent tissue sample of your cancer for some tests. 
 
The trial team want to:

  • check for the levels of a protein called PD-L1
  • check proteins called EGFR and ALK
  • look for biomarkers

The team would also like to store this sample for future research. They will give you more information and answer any questions you have.

If your cancer comes back, the trial team would like to take another sample of your cancer. This is to look at why the cancer has returned in more detail. This is optional. You can say no and still take part in the trial. 

Hospital visits

You see a doctor and have some tests before taking part. These tests include:

  • CT scan or MRI scan of your chest and tummy (abdomen)
  • CT scan or MRI scan of your brain
  • blood tests
  • pregnancy test – if there is any chance you could become pregnant

Tests and scans during monitoring (surveillance)
You have an MRD test every 6 weeks and a CT scan every 12 weeks. This will continue for about 2 years.

Tests and scans during the second screening
You see a doctor and have some tests to see if you are able to join the treatment part of the trial. These tests include:

  • CT or MRI scan of your tummy (abdomen) and brain
  • heart trace (ECG Open a glossary item)
  • blood and urine tests

Tests and scans during treatment
You have a CT scan every 8 weeks. You have a blood test before every dose of the study drug. You might have some other tests and scans if your doctor thinks this is needed.

Follow up (MRD negative)
The trial team ask you to take part in an observation period. You don’t have to take part in this. It lasts for up about 2 years.

You visit the hospital around 8 times. You have similar tests as people having usual follow up after lung cancer. These include:

  • CT scans every 12 weeks
  • blood tests every 8 weeks

After treatment (MRD positive)
After treatment you visit the hospital:

  • 4 weeks after you finish treatment
  • 12 weeks after you finish treatment

You then see the trial team every 12 weeks for a visit until the study ends.

At each visit the team will catch up with you to see how you are. You have a CT scan or MRI scan at each visit.

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 can affect the immune system. It may cause inflammation in different parts of the body. This can cause serious side effects. They 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 tell your doctor or nurse as soon as possible. You should tell them that you are on or have been on an immunotherapy.

The most common side effects of durvalumab are:

  • diarrhoea
  • skin rash or dry, itchy skin
  • tummy (abdominal) pain
  • a sore throat, runny or stuffy nose – due to an upper respiratory tract infection
  • cough
  • high temperature (fever)
  • your thyroid gland Open a glossary item not making enough hormone. Symptoms may include tiredness, weight gain, feeling the cold more, constipation, muscle weakness, slow heart rate, puffy face, dry skin, thinning hair and memory problems. 

We have more information on the side effects of durvalumab.
