Haemophilia gene therapy shows early success

Just one injection could be enough to mean people with haemophilia B no longer need medication, according to an early study in the UK and the US.

Six patients were given a virus that infects the body with the blueprints needed to produce blood-clotting proteins. Four of them could then stop taking their drugs.

Doctors said the gene therapy was "potentially life-changing".

Other researchers have described it as a "truly a landmark study."

People with haemophilia B have an error in their genetic code, which means they cannot produce a protein called factor IX, which is critical for blood-clotting.     Full Read
