Successful Applications of Gene Therapy
Over 1600 clinical trials have been conducted using gene therapy approaches. The Journal of Gene Medicine maintains an excellent publicly accessable database of all such studies.
Despite this, progress into actual clinical products has been slow although increasingly more and more clinical trials are reaching phase III and have a good chance of becoming licensed products for a range of diseases.
In humans the most successful set of trials to date have been for the severe immune deficiency disease ADA-SCID. Much of this work is being conducted by the Centre for Immunodeficiency in London.
Although not relevant to human disease, two products have been licensed for use as veterinary medicinces. Novartis Animal Health have developed a DNA Vaccine against Infectious Salmon Anaemia and VGX Animal Health developed LifeTide, a growth hormone releasing hormone therapy aimed at improving health in farmed pigs.
