The Goals of Gene Transfer Therapy
Many gene therapies are under investigation for a range of conditions. No gene therapies for hemophilia A or B have been determined to be safe or effective or approved for use.
Researching the Possibilities
Introducing Working Genes
One goal of gene transfer therapy being investigated is to introduce working genes into the body to function in place of the mutated genes responsible for the genetic condition.
Also being researched is whether the new, working gene helps the body produce the protein it needs to function properly. For example, in hemophilia A or B, the goal is to allow the body to produce factor VIII or factor IX, respectively, on its own.
Eliminating or reducing treatment burdens
Ongoing research is trying to determine whether gene therapy can help the body produce the proteins it needs, possibly lessening or eliminating the need for other treatment and routine disease management. Research is also looking at whether it might increase or lessen the physical, mental, and emotional burdens of disease. Although gene therapy may not be able to address preexisting damage, trials are also testing whether it may be able to slow the progression of any future damage.
