A trial of lenvatinib and pembrolizumab for liver cancer (LEAP 002)

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

Cancer type:

Liver cancer

Status:

Closed

Phase:

Phase 3

This trial is looking at comparing lenvatinib on its own with lenvatinib and pembrolizumab for advanced liver cancer.

Advanced liver cancer is liver cancer that has spread into the near by tissues or to another part of the body.

More about this trial

Lenvatinib is a targeted drug called a cancer growth blocker. Doctors can use lenvatinib to treat advanced liver cancer. 

Pembrolizumab is an immunotherapy called a monoclonal antibody (MAB). Pembrolizumab works by stimulating the immune system Open a glossary item to fight cancer cells. 

Researchers are always looking to improve treatment. They think that adding pembrolizumab to lenvatinib might be better for people with advanced liver cancer. 

To find out if it is better half the people in this trial will have lenvatinib and pembrolizumab. The other half will have lenvatinib and a dummy drug (placebo Open a glossary item).

The aims of this trial are to find how:

  • well the combination of lenvatinib and pembrolizumab works 
  • safe this combination is 
  • it affects quality of life Open a glossary item
  • well the body handles this combination

Trial design

This is an international phase 3 trial. The team need 750 people worldwide to join with 30 people form the UK.

This is a randomised trial. Everyone is put into 1 of 2 groups. Neither you nor your doctor can choose which group you are in. The groups are:

  • lenvatinib and pembrolizumab
  • lenvatinib and a dummy drug (placebo)

Lenvatinib is a capsule. You take it once a day. Your doctor will tell you how many to take. You take the capsules at home apart from the days you have pembrolizumab or the dummy drug. On these days you take the lenvatinib capsule at the hospital about an hour after pembrolizumab or the dummy drug. 

You have pembrolizumab or the dummy drug as a drip into a vein. You have it every 3 weeks. It takes about 30 minutes to have. 

You continue to have lenvatinib as long as it is helping and the side effects aren’t too bad. You continue to have pembrolizumab or the dummy drug for up to 2 years as long as it is helping and the side effects aren’t too bad.

You have a card that says you are taking part in this trial. It has information about the trial and contact numbers of the trial team. You should always carry this card. 

Samples
You give several blood samples throughout the trial. Researchers will use these to find out what happens to lenvatinib and pembrolizumab in the body when they are taken together. They will also look for substances (biomarkers Open a glossary item) in the blood that might show how well treatment is working.

You give a poo (stool) sample before starting treatment then:

  • at 2 different times during treatment
  • at the end of treatment

Researchers will use this sample to look for substances (biomarkers) that might show:

  • how well the treatment might work
  • how well the treatment is working 

You don’t have to give this poo sample if you don’t want to. You can still take part in the trial. 

Quality of life
You fill in a few questionnaires before starting treatment then

  • every 3 weeks for 27 weeks then
  • every 6 weeks for up to a year

The questions ask about:

  • how you are
  • what you can do 
  • any side effects you might have

Hospital visits

You see the doctor to have some tests before you start. These tests include:

During treatment you see the doctor every 3 weeks for:

  • a physical examination
  • blood tests
  • heart trace
  • CT scan and or an MRI scan

When you finish treatment you see the doctor for a physical examination and blood tests. You then see the doctor a month and 2 months later:

  • to see how you are
  • for a CT scan and or an MRI scan
  • heart trace
  • heart scan

Your doctor will then tell you how often they want to see you.

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. 

Pembrolizumab can affect the immune system. It may cause inflammation in different parts of the body which 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, 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 pembrolizumab are:

  • itching 
  • diarrhoea
  • cough
  • joint, back or tummy (stomach) pain
  • rash
  • high temperature (fever)
  • loss of skin colour
  • the thyroid not making enough hormones (hypothyroidism) causing tiredness, weight gain, feeling cold and constipation
  • low levels of salt in the blood causing tiredness, confusion, headache and muscle cramps 

Lenvatinib can cause some serious side effects that can be life threatening and might need urgent medical attention. You need to tell your doctor straight away if you have any of the following side effects. 

The most common serious side effects of lenvatinib are:

  • stroke, mini stroke or bleeding in the brain causing numbness and weakness on one side of the body
  • blood clot in the legs causing swelling of the lower leg muscle (calf muscle) that is warm and tender or a blood clot in the lungs (pulmonary embolism) that can cause sudden onset of shortness of breath, rapid breathing, tight feeling in the chest or chest pain, cough or coughing up blood, fast heart rate and a blue colour in the lips
  • heart problems, feeling your own heart beat (palpitations), heart attack or not being able to pump as well (heart failure) causing severe shortness of breath
  • an abnormal opening between 2 parts of the body or from inside to the outside of the body (fistula) or a hole forming in the bowel (bowel perforation)
  • bleeding inside the body particularly from the gut that might cause blood in the poo or black, tarry poo
  • not enough fluid in your body (dehydration) and your kidneys not working
  • liver damage causing yellowing of the skin or eyes, loss of appetite, tummy pain or high temperature
  • changes to the way your brain works causing confusion, drowsiness, poor concentration and loss of consciousness 

Other common side effects include:

Your doctor or a member of the trial team will talk to you about the side effects of lenvatinib and pembrolizumab before you agree to take part in this trial.
