Layla Richards was diagnosed with leukaemia at fourteen weeks of age and the chemotherapy and bone marrow transplant used were unsuccessful. Although doctors suggested her parents consider a pre-mortem, pain-relieving drug treatment, the parents decided to take whatever measures would help save the girl's life. A few weeks after receiving the first dose of the innovative drug, baby Layla began to recover.

The girl is not yet fully recovered and doctors suggest that this type of treatment should be approached with a great deal of caution at this stage - it is unclear what the results will be in the long term and to what extent it will work for other patients. However, this does not change the fact that it marks the emergence of a new option among potential treatments not only for leukaemia, but also for other cancers.
