Kirthana Balachandran
The NHS will offer the first gene-editing therapy for beta thalassaemia, a significant breakthrough. Stem cells will be reprogrammed to correct the blood disorder and eliminate the need for regular blood transfusions. People with beta thalassaemia lack sufficient haemoglobin, causing fatigue and shortness of breath. Kirthana, diagnosed as a baby, experiences muscle pain and palpitations, fearing a life dependent on transfusions.
The therapy utilizes Crispr technology, resembling a GPS-guided scissor, to switch the body’s haemoglobin production from adult to fetal types. By targeting the genetic switch, the treatment revives fetal haemoglobin production. Abdul, a trial participant, experienced improved health post-therapy. Long-term monitoring results showed minimal need for blood transfusions post-treatment.
The therapy’s £1.6m price tag has been negotiated by NHS England, making it accessible to eligible patients. Amanda Pritchard, NHS chief, heralds the therapy’s availability as historic. The treatment offers hope to those with beta thalassaemia, predominantly prevalent in certain ethnic groups.
