'Designer' cells save baby from leukaemia

A baby whom doctors thought almost certain to die has been cleared of a previously incurable leukemia in the first human use of an "off-the-shelf" cell therapy from Cellectis that creates designer immune cells.

One-year-old Layla had run out of all other treatment options when doctors at Britain's Great Ormond Street Hospital (GOSH) gave her the highly experimental, genetically edited cells in a tiny one-millilitre intravenous infusion.
