A trial looking at atezolizumab and cabozantinib for non small cell lung cancer that has spread (CONTACT 01)

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
Secondary cancers




Phase 3

This trial is comparing atezolizumab and cabozantinib with docetaxel for people with non small cell lung cancer. 

It is for people whose cancer has spread elsewhere in the body. This is advanced lung cancer.

More about this trial

Doctors are looking for ways to improve treatment for people with advanced non small cell lung cancer (NSCLC)

In this trial they are looking at a new combination of drugs. This includes 2 drugs called atezolizumab and cabozantinib

Atezolizumab is a drug you may have to treat advanced NSCLC that has got worse. It is an immunotherapy. It helps the immune system Open a glossary item to find and kill cancer cells. 

Cabozantinib is a type of cancer growth blocker. It stops signals that cancer cells use to divide and grow. It is a new drug for lung cancer. Researchers want to find out if adding it to atezolizumab slows cancer growth. 

Docetaxel is a chemotherapy drug. It is a usual treatment for NSCLC that has spread. 

In this trial some people have atezolizumab and cabozantinib. And some people have docetaxel.

The main aims of the trial are to:

  • find out how safe it is to have atezolizumab and cabozantinib together
  • find how well this combination of treatment works compared to docetaxel
  • learn more about the side effects

Trial design

This is a phase 3 trial. It is taking place worldwide. The researchers need 350 people to take part including at least 15 from the UK. 

It is randomised trial. You are put into a group by a computer. Neither you nor your doctor will be able to decide which group you are in. There are 2 treatment groups. You have 1 of the following:

  • atezolizumab and cabozantinib
  • docetaxel

You have treatment for as long as it is working and the side effects aren’t too bad.

Atezolizumab and cabozantinib
You have atezolizumab as a drip into a vein. You have it once every 3 weeks. 

Cabozantinib is a tablet. You take them once a day, every day.

You have docetaxel as a drip into a vein. You have it once every 3 weeks.

Blood and tissue samples
The researchers ask you to give an extra tissue sample. They also ask to take some extra blood samples. Where possible, you have these at the same time as your routine blood tests.

The researchers use the samples to look for differences in substances called biomarkers Open a glossary item. This can help researchers to work out why treatment might work for some people and not for others.

You need to agree to give most of the samples in the trial. There are a few you don’t need to agree to if you don’t want to. The team can let you know more about this.

Hospital visits

You see a doctor and have some tests before you can take part in the trial. These include:

You may also need to give a tissue sample (biopsy Open a glossary item).

During treatment you see the doctor every 3 weeks for a check up and blood tests. 

You have a CT or MRI scan:

  • every 6 weeks in the first year and then
  • every 9 weeks until your cancer gets worse 

When you finish treatment you see the doctor 1 month later. If your cancer hasn’t got worse you continue to have scans every 6 to 9 weeks. You have a final scan after about 6 weeks if your cancer gets worse.

Follow up
The team follow you up every 3 months when you finish treatment. You might see them at a routine hospital appointment or they may call you to see how you are getting on.

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. 

Atezolizumab 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. You should tell them you are on or have been on an immunotherapy.

The most common side effects of atezolizumab are:

  • tummy (abdominal) pain
