UK approves groundbreaking gene therapy treatment for sickle cell

The UK’s medicines watchdog has approved a groundbreaking gene therapy treatment for sickle cell disease – which could transform the lives of thousands of people with the debilitating blood disorder.

The treatment – called Casgevy – works by editing faulty genes to help the body produce functioning haemoglobin –  and experts have called it “an historic moment for the sickle cell community”.
