The
future of Hemophilia is Gene Therapy. Currently we treat those with Hemophilia
by supplying them with the missing protein coagulation factor
they lack, but this treatment does not actually cure the patient and has a very
high treatment burden. The current goal of the future is to find
a way to correct the harmful mutation that leads to the Hemophilia
disorders manifestation. Positive results from gene therapy have
been achieved in animals such as dogs and mice, but we have yet to break
through with a humans.
"Before the gene treatment, the animals
experienced about five serious bleeding events a year. After receiving the
novel gene therapy, though, they experienced substantially fewer bleeding
events over three years, as reported in the journal Nature
Communications."
"“We’ve cured mice 10 different ways,” says Trent Spencer, Ph.D., director of the Gene Therapy Laboratory at the Aflac Cancer Center and Assistant Professor of Pediatrics with Emory University School of Medicine.
“We can cure a mouse of
hemophilia with our eyes closed. Getting from a mouse to a human, however, is a
massive step and that is what we’re trying to do now.”
Currently the biggest block in the progression
of gene therapy is the potential commercialism of a new treatment. Companies
are less willing to invest in creating a product that would be very
expensive initially to offset the development cost, as well as
possibly unpopular due to moral concerns. Why risk bringing gene
therapy treatments to the market when you already have a working,
profitable traditional hemophilia treatments in place?
Those with the most to gain from a gene therapy treatment for hemophilia
would be individuals living in developmental countries. One
hight-tech intervention is much more feasible than creating
an infrastructure that would allow for
an individual to receive daily treatments. It will be
interesting to see where Hemophilia is ten years from now, when the cost
of gene therapy may be cheaper and the general public
more accepting of gene manipulation.
