The treatment, previously only tested in the laboratory, was used in one-year-old, Layla, who had relapsed acute lymphoblastic leukaemia (ALL). She is now cancer free and doing well.
This breakthrough comes from GOSH and UCL Institute of Child Health’s (ICH) pioneering research teams with support from the National Institute for Health Research (NIHR) Great Ormond Street Biomedical Research Centre, who together are developing treatments and cures for some of the rarest childhood diseases.
Chemotherapy successfully treats many patients with leukaemia but it can be ineffective in patients with particularly aggressive forms of the disease where cancer cells can remain hidden or resistant to drug therapy. Recent developments have led to treatments where immune cells, known as T-cells, are gathered from patients and programmed using gene therapy to recognise and kill cancerous cells. Multiple clinical trials are underway, but individuals with leukaemia, or those who have had several rounds of chemotherapy, often don’t have enough healthy T-cells to collect and modify meaning this type of treatment is not appropriate.
