Britain’s National Health Service (NHS) will offer a groundbreaking gene therapy to treat sickle cell disease, as announced by the National Institute for Health and Care Excellence (NICE) on Friday. Developed by Vertex Pharmaceuticals and CRISPR Therapeutics, the treatment costs approximately £1.65 million ($2.1 million) per patient.
The therapy was approved by Britain’s Medicines and Healthcare products Regulatory Agency (MHRA) in 2023, making it the first regulator in the world to authorize its use. NICE, responsible for evaluating medical technologies for NHS adoption, has determined that around 50 patients per year will be eligible for the treatment.
Sickle cell disease is a lifelong and severe genetic disorder caused by mutations in the haemoglobin-producing genes, leading to abnormal red blood cells that hinder oxygen transport throughout the body. The new therapy utilizes CRISPR gene-editing technology to modify stem cells extracted from a patient’s bone marrow. These edited cells are then reintroduced into the patient to correct the genetic defect.
A similar gene-editing treatment was approved for NHS use in August to treat beta thalassemia, another rare blood disorder. This advancement marks a significant step forward in precision medicine and gene therapy.
