Gene-Edited Cells Keep Cancer Babies Well More Than One Year On

January 25, 2017

(Reuters) – Two babies rescued from previously incurable leukemia after receiving infusions of gene-edited immune cells are doing well at home more than a year after initial treatment, scientists said on Wednesday. Layla Richards became the first person in the world to get the “off-the-shelf” cell therapy developed by French biotech firm Cellectis at Britain’s Great Ormond Street Hospital in 2015. A second girl was treated soon afterwards. Now the team involved in both cases have published details of their work in a peer-reviewed journal, reporting that the two girls remained disease-free 18 and 12 months after treatment respectively.
