Gene therapy technologies are described in detail including viral vectors, nonviral vectors and cell therapy with genetically modified vectors. Gene therapy is an excellent method of drug delivery and various routes of administration as well as targeted gene therapy are described. There is an introduction to technologies for gene suppression as well as molecular diagnostics to detect and monitor gene expression.
Clinical applications of gene therapy are extensive and cover most systems and their disorders. Full chapters are devoted to genetic syndromes, cancer, cardiovascular diseases, neurological disorders and viral infections with emphasis on AIDS. Applications of gene therapy in veterinary medicine, particularly for treating cats and dogs, are included.
Research and development is in progress in both the academic and the industrial sectors. The National Institutes of Health (NIH) of the US is playing an important part. As of January 2010, over 2024 gene therapy clinical trials have been completed, are ongoing or have been approved worldwide. A breakdown of these trials is shown according to the areas of application.
Since the death of Jesse Gelsinger in the US following a gene therapy treatment, the FDA has further tightened the regulatory control on gene therapy. A further setback was the reports of leukemia following use of retroviral vectors in successful gene therapy for adenosine deaminase deficiency. Several clinical trials were put on hold and many have resumed now. The report also discusses the adverse effects of various vectors, safety regulations and ethical aspects of gene therapy including germline gene therapy.
