A trial looking at pembrolizumab with or without sacituzumab govitecan for non small cell lung cancer that has spread (KEYNOTE D46/EVOKE-03)

Cancer type:

Lung cancer
Non small cell lung cancer
Secondary cancers

Status:

Open

Phase:

Phase 3

This trial is looking at a targeted cancer drug called sacituzumab govitecan in combination with the immunotherapy drug pembrolizumab. The trial team are comparing this treatment to pembrolizumab alone.

You pronounce sacituzumab govitecan as sass-ih-too-zo-mab go-vih-tee-kan.

It is for people with non small cell lung cancer and:

  • the cancer has spread from where it started to other parts of the body (advanced cancer)
  • more than half (more than 50%) of the lung cancer cells have a protein called PD-L1 on their surface
  • they have not had treatment for their advanced lung cancer before

More about this trial

There are a number of treatments for non small cell lung cancer that has spread. 

Treatments such as chemotherapy, radiotherapy or targeted cancer drugs can help to shrink the cancer, reduce symptoms and help people to feel better.

Doctors are trying to improve treatment for people with advanced lung cancer. They think an immunotherapy Open a glossary item drug called pembrolizumab and a targeted cancer drug Open a glossary item called sacituzumab govitecan could work well together but they aren’t sure. They are doing this trial to try and find out.

Sacituzumab govitecan is an antibody drug conjugate Open a glossary item. This means that it is a type of drug with two parts:

  • sacituzumab - a monoclonal antibody Open a glossary item
  • SN-38 - a chemotherapy drug Open a glossary item

The sacituzumab finds specific proteins on cancer cells and delivers chemotherapy to the cell to kill it.

Pembrolizumab stimulates the body's immune system Open a glossary item to fight cancer cells. It does this by targeting and blocking a protein called PD-1 on the surface of certain immune cells called T cells Open a glossary item. Blocking PD-1 triggers the T cells to find and kill cancer cells.

The main aims of the trial are to:

  • look at the safety of pembrolizumab with and without sacituzumab govitecan for advanced non small cell lung cancer
  • see how well pembrolizumab and sacituzumab govitecan work together compared to pembrolizumab alone
  • find out about the quality of life Open a glossary item of people taking part
  • get more information about the side effects of treatment

Who can enter

The following bullet points are a summary of the entry conditions for this trial. Talk to your doctor or the trial 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 trial if all of the following apply. You:

  • have non small cell lung cancer that has spread outside the lungs. This is stage 4 non small cell lung cancer (NSCLC). You might be able to take part if your cancer is a mix of NSCLC and another type, unless you have any small cell lung cancer cells. Your doctor can explain more.

Trial design

This phase 3 trial is taking place worldwide. The trial team need 614 people to take part.

It is a 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:

  • pembrolizumab and sacituzumab govitecan
  • pembrolizumab

You have treatment in cycles Open a glossary item. Each cycle lasts for 3 weeks. You have all your treatment as a drip into a vein.

Pembrolizumab and sacituzumab govitecan
You have sacituzumab govitecan on the trial for as long as it is working, and the side effects are not too bad. 

You have pembrolizumab for up to 2 years on the trial. This is as long as the drug is working, and the side effects are not too bad.

Pembrolizumab alone
You have treatment for up to 2 years on the trial, as long as it is working, and the side effects are not too bad.

Everyone taking part
You stop treatment if your cancer gets worse. The trial doctor will talk to you about other treatment options.

Samples for research
The researchers might ask you to give a sample of cancer tissue if there isn’t already a suitable one that they can access. They also ask to take some extra blood samples. Where possible, you have these at the same time as your routine blood tests.

They plan to use the samples to:

  • see how well the treatment is working
  • look at genes Open a glossary item to understand more about non small cell lung cancer
  • look for substances called biomarkers Open a glossary item to help work out why treatment might work for some people and not for others
  • help develop and improve tests for people with cancer

Quality of life
The trial team ask you to use a computer at the clinic to answer questions about how you are feeling and your day-to-day life. This is called a quality of life study.

You fill in the questionnaires:

  • before you start treatment
  • before every cycle of treatment for a year
  • before every other cycle of treatment after a year

Hospital visits

You see the doctor and have tests before you can take part. These might include:

  • blood tests
  • urine tests
  • a physical examination Open a glossary item
  • a pregnancy test - if there is any chance you could become pregnant
  • heart trace (ECG Open a glossary item)
  • CT scan or MRI scan Open a glossary item
  • a biopsy - if there is not a recent tumour sample available

Having treatment
You have treatment as an outpatient in the hospital. This means you don’t need to stay overnight. 

You have pembrolizumab on day 1 of your 3 week cycle. And sacituzumab govitecan on day 1 and day 8 of your 3 week cycle.

So you go into hospital:

  • around twice every 3 weeks if you are having pembrolizumab and sacituzumab govitecan
  • around once every 3 weeks if you are having just pembrolizumab

The trial team will also contact you about 1 week after each visit to check how you are getting on.

Tests during treatment
You have some tests at each hospital visit, including blood and urine tests. Your doctor will let you know which tests to expect and when.

You have scans Open a glossary item during treatment to see how well the treatment is working.

You have a scan around every 6 weeks for the first 4 months after randomisation Open a glossary item. You then have a scan around every 9 weeks for the rest of the first year of treatment.

You then have a scan around every 3 months until you stop treatment.

You have a scan when you finish treatment on the trial. The trial team will ask you to still have scans every 3 months if you stop treatment, but your cancer has not got worse.

Follow up
The trial team monitor you on the trial after you finish treatment.

You have a hospital visit about 30 days after you finish treatment. You have some tests at this visit, including blood tests. Your doctor will let you know which tests to expect.

You have hospital visits every 9 to 12 weeks unless your cancer gets worse, or you start other cancer treatments. The trial doctor will let you know your follow up schedule.

Then the trial team will get in touch with you around every 3 months to see how you are feeling and 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. 

Pembrolizumab 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.

The most common side effects of pembrolizumab are:

  • itchy skin or a skin rash
  • diarrhoea
  • cough
  • joint, back or tummy pain
  • fever
  • loss of skin colour
  • not enough thyroid Open a glossary item hormone. This might mean you feel tired, gain weight, feel cold or have constipation.
  • low levels of salt in the blood. This might mean you feel tired, confused, have a headache, have muscle cramps or feel sick.

The most common side effects of sacituzumab govitecan include:

  • an allergic reaction Open a glossary item. This could cause a skin rash or hives, breathing problems, wheezing, feeling dizzy or lightheaded, fast pulse, sweating or swelling around the mouth, throat or eyes.
  • a drop in the number of blood cells causing an increased risk of infection, tiredness, and breathlessness
  • feeling or being sick 
  • diarrhoea or constipation
  • pain in the tummy (abdomen) or joint pain 
  • tiredness (fatigue)
  • urine infections 
  • weight loss, loss of appetite or both 
  • low levels of magnesium, potassium, or phosphate in the blood 
  • lack of fluids in the body (dehydration)
  • headache
  • dizziness
  • shortness of breath with or without exercise
  • cough
  • skin rash or itchy skin
  • hair loss

You might have more severe side effects with a combination of the drugs. Your doctor will talk to you about this. You’ll have a chance to ask any questions you may have. 

Let your doctor know if you know you have the UGT1A1*28 gene. This means you may be more likely to have side effects from sacituzumab govitecan including changes to the production of blood cells. Your doctor can explain more.

We have more information about pembrolizumab including possible side effects.
