A study of immunotherapy and targeted drugs for kidney cancer (sub study 03A)

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

Cancer type:

Kidney cancer
Renal cell cancer
Secondary cancers

Status:

Closed

Phase:

Phase 1/2

The main study (KEYMAKER-U03) is looking at combinations of immunotherapy and targeted drugs for a type of kidney cancer called renal cell cancer. 

Sub study 03A is part of the main study. It is open to people with a type of kidney cancer called renal cell cancer that has:

  • spread (advanced cancer Open a glossary item) and
  • they haven’t had treatment for the cancer spread

More about this trial

Doctors can treat advanced renal cell cancer with the combination of pembrolizumab and lenvatinib

Pembrolizumab is an immunotherapy. It works by helping the immune system Open a glossary item to find and attack cancer cells. 

Lenvatinib is a targeted drug Open a glossary item called a cancer growth blocker. It works by stopping:

  • signals that tell the cancer cells to grow
  • the cancer making new blood vessels which they need to grow

This stops the cancer cells from growing. 

In this sub study the study team are looking at the following drugs:

  • belzutifan (MK-6482)
  • MK-4280A
  • MK-1308A
  • MK-7486A

Belzutifan is a drug doctors use to treat people with an inherited Open a glossary item condition called Von Hippel-Lindau syndrome Open a glossary item and renal cell cancer.

MK-4280A, MK-1308A and MK-7486A are combinations of pembrolizumab and another immunotherapy. 

The main aims of the sub study are to find out:

  • how safe these treatments are
  • how well these treatments work
  • what happens to these treatments in the body and how they affect the body

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. 

Who can take part

You may be able to join this study if all of the following apply. You:

  • have a type of kidney cancer called renal cell cancer that has spread into the surrounding tissue (locally advanced) or to another part of the body (metastatic). This is stage 4 renal cell cancer.
  • have not had any systemic treatment Open a glossary item for your stage 4 renal cell cancer

Trial design

This an international phase 1/2 study. The team need up to 390 people to take part with 27 people from the UK.

It is a randomised study. A computer puts you into treatment groups. Neither you nor your doctor chooses which group you are in. There are 5 treatment groups:

  • pembrolizumab and lenvatinib
  • MK-1308A and lenvatinib
  • MK-4280A and lenvatinib
  • pembrolizumab, lenvatinib and belzutifan
  • MK-7684A and belzutifan 

Pembrolizumab and lenvatinib is the control group Open a glossary item. The other groups are the test (experimental Open a glossary item) groups. You have a higher chance of going into one of the experimental groups than the control group. 

You have the following as a drip into a vein:

  • pembrolizumab
  • MK-1308A
  • MK-4208A
  • MK-7684A

You have pembrolizumab and MK-1308A once every 3 weeks or 6 weeks. You have them for up to 2 years. 

You have MK-4208A and MK-7684A once every 3 weeks for up to 2 years.

Lenvatinib and belzutifan are tablets. You take the tablets once a day. Your doctor will tell how many to take and whether you take them on an empty stomach or with a meal. 

You continue to have treatment as long as it is helping and the side effects aren’t too bad. 

Samples for research
You give extra blood samples and tissue samples (biopsies Open a glossary item) as part of the study. Where possible the team take these samples when you have blood tests and tissue samples taken as part of your routine care. 

The team use these samples to:

  • find out how the treatments affect the body and what happens to the treatments in the body
  • look at the genes Open a glossary item  in the cancer cells
  • look for substances (biomarkers Open a glossary item

This can help researchers to find out:

  • how well the treatments are working
  • what affects how well the treatments work
  • more about the treatments 

They might also ask to store your samples for researchers to use in the future. Your samples will be anonymous.

Hospital visits

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

You see the doctor regularly during treatment. This is:

  • for blood tests and urine tests
  • to see how you are
  • to ask what daily activities you can do
  • to ask about side effects

You have a scan at 3 months and then every 6 weeks while having treatment. If a scan shows your cancer is getting worse your doctor will talk to you about whether you should continue with the study treatment. They will also speak to you about what other treatments there might be if you do stop having the study treatment.

If you are having lenvatinib you will have regular heart traces and heart scans done. Your doctor will tell you how often you are to have them. 

You see the doctor at the end of treatment and a month later. This is to see how you are and to ask about any side effects.

After treatment if your cancer has not got worse you see the doctor every 6 weeks or 12 weeks. You also have a scan. 

If  your cancer has got worse the doctor or nurse will contact you at least every 12 weeks to see how you are.  

You might continue to see the doctor as part of study for up to 5 years.

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, MK-1308A, MK-4280A and MK-7684A can affect the immune system Open a glossary item. This may cause inflammation Open a glossary item and other reactions in different parts of the body. For many people the inflammation and reactions are not too bad. For some people they can cause serious side effects. 

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.
 
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.

 

Researchers have looked at the combination of pembrolizumab and lenvatinib in other clinical trials. The side effects of these 2 drugs are the same whether you take them together or separately. The most common side effects from having pembrolizumab in combination with lenvatinib are:

  • a low level of thyroid hormones causing tiredness, weight gain, feeling cold and constipation
  • inflammation of the pancreas causing tummy pain, feeling or being sick
  • inflammation of the adrenal glands causing tiredness, weight loss, weak muscles, feeling faint, diarrhoea and aching tummy, joints or muscles 
  • inflammation of the kidneys causing passing urine less often, cloudy urine, blood in the urine or lower back pain 

MK-1308A is a new drug and there might be side effects we don’t know about yet. The most common side effects we do know of are:

  • skin rash and or itchy skin
  • inflammation of the lungs causing shortness of breath and or a cough
  • too much thyroid hormone causing anxiety, feeling angry, trouble sleeping, weakness, trembling, sweating, tiredness and diarrhoea
  • a low level of thyroid hormones causing tiredness, weight gain, feeling cold and constipation

MK-4280A is a new drug and there might be side effects we don’t know about yet. The most common side effects we do know about are:

  • itchy skin and or rash

Doctors use belzutifan to treat renal cell cancer that has a link to Von Hippel-Lindau syndrome. But not for renal cell cancer by itself so there might be side effects we don’t know about yet when treating renal cell cancer only. The most common side effects of belzutifan we do know about are:

MK-7684A is a new drug and there might be side effects we don’t know about yet. The most common side effects we do know about are:

  • tiredness (fatigue)
  • skin rash and or itchy skin
  • loss of appetite

  • high temperature (fever)
  • chills 
  • a low level of thyroid hormones causing tiredness, weight gain, feeling cold and constipation
  • changes to how your pancreas and liver works
  • a drop in red blood cells causing tiredness and shortness of breath
  • joint pain

You might have reactions while you are having MK-7648A. These include:

  • feeling dizzy or faint
  • redness (flushing)
  • rash
  • high temperature
  • feeling short of breath
  • drop in blood pressure
  • pain where MK-7648A is going into the vein
