E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The principal research question is whether immunisation with a pneumococcal vaccine (13vPCV) can be used to protect children with Acute Lymphoblastic Leukaemia from pneumococcal infection. It will seek to identify the earliest time-point in treatment that children can be effectively vaccinated in order to protect children from this infection for as long as possible, when they are most at risk of infection. Specifically, it will investigate whether protective pneumococcal immunity can be achieved by immunising with 13vPCV:
a) during leukaemia treatment (during maintenance chemotherapy)?
b) at the end of leukaemia treatment?
c) 6 months after completion of leukaemia treatment?
|
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives of the study are:
1. To establish if the side effcts of a pneumococcal vaccine (13vPCV)are tolerable and acceptable in children with Acute Lymphoblastic Leukaemia (ALL).
2. To document any cases of pneumococcal infection in the study population
3. To document how many children carry different pneumococcal types in this population. This is important to ensure that the different types of pneumococcal contained in the vaccine are appropriate for the population.
4. To describe the effects on the immune system of current ALL chemotherapy treatment. |

|
|
E.4 | Principal exclusion criteria |
Exclusion criteria:
i) Concomitant acquired or congenital immunodeficiency
ii) Concomitant immunosuppressive medication within previous 3 months, other than maintenance chemotherapy as per UKALL 2003 protocol
iii) Previous severe or anaphylactic reaction to PCV

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measure will be the percentage of children who have protective levels of anti-pneumococcal antibodies (as defined by WHO) 1 month post-13vPCV immunisation.

E.5.2 | Secondary end point(s) |

ii) Pneumococcal serotype carriage in children receiving treatment for ALL |
