Phase:

Phase 2

This trial looked at avelumab for peripheral T cell lymphoma that had come back or where treatment had stopped working.

The trial was open for people to join between 2017 and 2019. The team presented the results at a conference in 2020.

More about this trial

Peripheral T cell lymphoma (PTCL) is a type of non-Hodgkin lymphoma (NHL) that affects blood cells called T cells.
 
Chemotherapy is often used to treat PTCL. But sometimes it continues to grow or comes back after treatment. 

Researchers wanted to see how well a drug called avelumab works. Avelumab is a type of immunotherapy. It stimulates the body’s immune system to recognise and kill cancer cells.
 
The main aims of the trial were to find out:

  • how well avelumab works
  • more about the side effects    

Summary of results

The research team found that avelumab was not a useful treatment for peripheral T cell lymphoma (PTCL).

Trial design
This trial was for people with PTCL that had come back or got worse despite at least 1 other treatment. 

Everyone taking part had avelumab. They had treatment for as long as it was working and they weren’t having serious side effects. They were due to have scans at 3, 6 and 8 months to see how well the treatment was working.

Results
A total of 32 people had treatment as part of this trial. Of those, 16 people stopped treatment before the first scan at 3 months. The most common reason was that they were too poorly because their lymphoma had got worse. 

The research team looked at how well the treatment had worked in the other 16 people. They found it had:

  • got a bit better in 5 people
  • stayed the same in 4 people
  • got worse in 7 people

When they looked at how long it was before people’s lymphoma started to get worse, they found it was about 3 months. They also looked at how long people lived and found it was about 9 months. 

This is about the same as you would expect with other treatments.

Side effects
Most people taking part had at least 1 side effect. Some were mild or didn’t last long. But 16 people had a side effect that was more severe. The most common side effects were infection and fever.

We have more information about the side effects of avelumab in our Cancer drugs section.

Conclusion
The research team concluded that avelumab does not appear to be a useful treatment for peripheral T cell lymphoma that has come back or got worse after other treatment. 

Even when a trial shows a treatment isn’t useful for a particular cancer, it adds to our knowledge and understanding of cancer and how to treat it. 

The team suggest avelumab may be more useful for specific subgroups, or in combination with other treatments.
