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

Cancer type:

Acute leukaemia
Acute lymphoblastic leukaemia (ALL)
Blood cancers

This trial is looking at a vaccine Open a glossary item to help prevent infections in children who are having or have recently finished treatment for acute lymphoblastic leukaemia (ALL).

The trial is for children and young people up to and including the age of 18. We use the term ‘you’ in this summary, but if you are a parent, we are referring to your child.

Chemotherapy can affect your immune system Open a glossary item, which helps to fight infection. Doctors know that children having chemotherapy for ALL are at increased risk of an infection called pneumococcus. In this trial doctors want to use a new vaccine to help protect against pneumococcal infection.

The aim of this study is to find out if a new vaccine can help prevent pneumococcal infection in children who are having or have just finished treatment for ALL.

Trial design

This trial will recruit 120 people from the UK. There are 3 treatment groups. Each group has the same vaccine. The vaccine is an injection into your thigh or arm muscle. You have 1 vaccination and are on the trial for a year.

  • Group 1 have the vaccine while they are having treatment to keep the ALL away (maintenance treatment)
  • Group 2 have the vaccine at the end of treatment
  • Group 3 have the vaccine within 6 months of finishing treatment

This study does not affect your cancer treatment and you see your cancer doctors while you are on the study.

Hospital visits

You will see the doctors and have some tests before you have the vaccine. The tests include

  • Physical examination
  • Blood tests
  • Swabs of your nose and throat

The study nurse will see you 1 month after your vaccination for blood tests and to see how you are. You see the study nurse again a year after the vaccination for blood tests and swabs of your nose and throat. This is the end of the trial.

Side effects

The most common side effects of the vaccination are pain, swelling, tenderness and redness where you had the injection. This will go after 1 or 2 days.
