"I was delighted to take part in a clinical trial as it has the potential to really help others in the future.”
A trial looking at pembrolizumab and lenvatinib for head and neck cancers (LEAP-010)
Please note - this trial is no longer recruiting patients. We hope to add results when they are available.
This trial is looking at whether having lenvatinib with pembrolizumab works better than pembrolizumab on its own as a treatment for head and neck cancer.
The trial is open to people who have one of following head and neck cancers:
- mouth cancer (oral cancer)
- cancer of the back of the mouth (oropharyngeal cancer) caused by the
human papilloma virus(HVP)
- cancer of the voice box (laryngeal cancer)
More about this trial
Pembrolizumab is an immunotherapy. It works by stimulating your
Lenvatinib is a
Researchers think that pembrolizumab with lenvatinib might work well to treat head and neck cancers. To find this out half the people in the trial have pembrolizumab and lenvatinib. And the other half have pembrolizumab and a dummy drug (
The aims of this trial are to find out:
- how safe it is to have pembrolizumab and lenvatinib
- how well this combination works
- how it affects
quality of life

This is an international phase 3 trial. The team need 500 people worldwide to join with 28 people from the UK.
This is a double blind randomised trial. You are put into treatment groups. Neither you nor your doctor can choose which group you are in. And neither you nor your doctor knows which group you are in. The treatment groups are:
- pembrolizumab and lenvatinib
- pembrolizumab and a dummy drug (
You have pembrolizumab as a drip into a vein. You have
You have pembrolizumab for 2 years as long as it is working and the side effects aren’t too bad.
After the 2 years you might be able to have another year of pembrolizumab. Your doctor will talk to you about this.
You have lenvatinib or the dummy drug as a capsule. You take the capsule once a day every day.
You have lenvatinib or the dummy drug as long as it is working and the side effects aren’t too bad.
You give extra blood samples during the trial. Researchers use these to look for substances (
They will also ask for a poo (stool) sample to look for biomarkers. You don’t have to give the poo sample if you don’t want to.
Quality of life questionnaires
You fill in 3 questionnaires:
- before each treatment
- at the end of treatment then
- a month later
The questions ask about:
- your general health
- what daily activities you can do
- any symptoms or side effects you might have
This is a quality of life study.
You see the doctor to have some tests when you agree to take part. These tests include:
- blood tests
- urine test
- mouth examination
- heart trace (
- heart scan (
- CT scan or MRI scan
During treatment you see the doctor regularly for a physical examination and blood tests. At some of these visits you also have a heart trace and a CT scan or MRI scan.
You see the doctor at the end of treatment for:
- a physical examination
- blood tests
- CT scan or MRI scan
- heart trace
- heart scan
You then see the doctor every 3 months until:
- your cancer starts to get worse or
- you start another treatment for your cancer or
- the end of the trial
The trial team will then contact you about every 3 months to see how you are until:
- the end of the study or
- you decide to withdraw from the study
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.
You have a card that shows you are taking part in this trial. On the card are the contact details of the trial team. Always carry this card with you. Show it to your GP when you see them or to staff at the emergency department of the hospital if you go there. This is so they can contact the trial team if necessary.
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.

- itching, rash, loss of skin colour
- a cough
- joint pain
- back pain
- high temperature (fever)
- tummy (stomach) pain

- blood clot in your lungs (pulmonary embolism) causing shortness of breath, rapid breathing, chest feeling tight, chest pain, cough, coughing up blood, fast heartbeat, blue lips
- heart problems including fast heart beat (palpitations), heart attack or your heart not being able to pump very well causing shortness of breath
- an abnormal opening (fistula) between parts of the body or to the outside of your body such as between the windpipe and the skin or between the bowel and the gut
- bleeding in the gut causing black, tarry poo or blood in the poo
