Scientists are to test if boosting the immune system can prevent the return of the childhood cancer neuroblastoma.
The disease - a cancer of developing nervous system tissue - is most often found in under-fives and accounts for about a sixth of child cancer deaths.
The Trial -
Works by hunting down neuroblastoma cells that have survived conventional treatment and attaching antibodies to specific molecules on their surface.
These antibodies then mobilise the body's immune defences to attack and destroy the cells.
