Phase 3

This trial looked at whether bevacizumab after surgery helped people live longer, or stopped melanoma coming back, in people who were at high risk of recurrence Open a glossary item.

This trial was supported by Cancer Research UK.

More about this trial

Doctors usually treat melanoma skin cancer with surgery. After this, you have regular check ups because there is a risk that the melanoma may come back. So far, there is no strong research evidence to show that having any treatment after surgery helped people live longer. So having regular check ups by surgeons is the standard treatment.

Bevacizumab (also known as Avastin) is a type of biological therapy called a monoclonal antibody. It seeks out and blocks a particular protein which is needed for the cancer cell to grow.

Doctors already use bevacizumab to treat a number of other advanced cancers. But it wasn't known whether it would help stop melanoma coming back after surgery.

The aims of this trial were to

  • Find out if bevacizumab after surgery could help people with melanoma live longer, or delay melanoma from coming back for longer
  • Learn more about the side effects
  • Find out if there were ways to predict who would benefit most from bevacizumab

Summary of results

The trial team found that bevacizumab increased the amount of time it took for melanoma to come back after surgery.

This was a phase 3 trial. It recruited 1,343 people. It was a randomised trial.

  • 671 people had bevacizumab
  • 672 people didn't have bevacizumab but had regular check ups

After a minimum of 5 years of follow up the team looked at how many people were still alive. 

  • 420 people had bevacizumab   
  • 418 people didn't have bevacizumab 

They also looked at the percentage of people who were free of cancer. 

  • 51 out of every 100 people (51%) had bevacizumab 
  • 45 out of every 100 people (45%) didn't have bevacizumab 

15 out of every 100 people (15%) who had bevacizumab had moderate to severe side effects. There was also an increased risk of high blood pressure.

The trial team concluded that bevacizumab did improve the amount of time people were free of melanoma after surgery. But didn't increase the amount of time they lived after surgery.
