The research, conducted by Lisa Kattenhorn and coauthors from Dimension Therapeutics in Cambridge, Massachusetts, the US, show the potential for additional technological improvements to expand the therapeutic applications of gene therapy to treat liver disease, UPI wrote.
The field of AAV gene therapy has progressed significantly over the past decade with the use of new capsid serotype and organ-specific promoters, scientists have developed an increased understanding of the immune response to AAV in liver-directed therapy.
Based on observations by Dr. Terence R. Flotte, editor-in-chief of Human Gene Therapy, as well as Celia and Isaac Haidak, who are professor of medical education and dean provost and executive deputy chancellor at the University of Massachusetts Medical School respectively: "AAV-based gene therapy to the liver has been a platform for transformational new therapies for genetic diseases such as hemophilia and inborn errors of metabolism.
"The review by Dr. Kattenhorn and colleagues provides an excellent overview of the current best knowledge in this area."
A number of clinical trials are planned and ongoing in liver-directed therapy in hemophilia A and B, as well as other liver disorders.
Researchers plan to explore areas of future development including re-administration of AAV gene therapy and minimizing the risk of hepatocellular carcinoma.
