Gene Therapy: The Future Is Now
WebMD News Archive
It will take longer to find solutions to certain diseases like diabetes and
sickle cell anemia, Anderson says, because they involve multiple genes.
"We're just getting over the cusp of being able to get a single gene in,
much less being able to get two genes in or three genes, and have them [work]
properly, and so on," he tells WebMD.
Some researchers are also having success with gene therapy in mice.
"There are a number of indications now that finally we've learned enough;
we've made the system efficient enough that gene therapy is now turning the
corner and is starting to see some success clinically," Anderson says.
Fears about safety have also calmed down, according to Anderson. He says
that out of hundreds of recent problems associated with clinical trials that
were investigated by the government, only one was linked to a gene-related
event: the death of the Arizona teen-ager, Jesse Gelsinger.
Is humanity facing a cure-all approach to treatment? Anderson tells WebMD
researchers are working on it. "Not quite that completely, but the answer
is yes -- but we're talking about 20, 30, 40 years. It is recognized that gene
therapy will revolutionize medicine. But the problem is, we all got a bit
carried away into thinking it was going to happen easily. Well, nothing major
happens easily in nature.
"My feeling is for the next three to five years, all we're going to see
is the occasional, little indication. I think we've got another five years of
hard work before gene therapy really starts to become mainline."
