Perhaps nothing lifts the spirits of struggling Huntington’s
disease families more than news about research breakthroughs.
With people emitting oohs and ahs about some of the key developments,
you could feel the excitement in the room Monday evening, September 24, as Jody
Corey-Bloom, M.D., Ph.D., presented her annual research update to the support
group of the San Diego Chapter of the Huntington’s Disease
Society of America (HDSA).
The director of the HDSA Center of Excellence for Family
Services and Research at the University of California, San Diego (UC San
Diego), Dr. Corey-Bloom kicked off the update with the hottest topic in the HD
research world: gene silencing techniques aimed at attacking the disease at its
roots.
“This is a big thing,” Dr. Corey-Bloom stated. “There are
actually two methods to accomplish this that are under way in research labs
around the world…. We want to switch off the gene that is responsible for Huntington’s
disease. A lot of people feel very good about these techniques.”
Before a room packed with some 50 support group
participants, Dr. Corey-Bloom proceeded to outline the efforts to set up
clinical trials to test RNA interference (click here to read more) and antisense
oligonucleotides (ASO) (click here to read more) as ways to block the negative
effects of the HD gene, which produces a harmful protein.
“If we can get rid of this harmful protein, there’s a good
chance that we could slow down the disease or even prevent it,” Dr. Corey-Bloom
explained.
A trial in 12 months?
“It’s likely that we’ll see both approaches being tried,”
Dr. Corey-Bloom said, noting, that, given the current state of the science, it
appears that the ASO approach will enter a trial first.
Dr. Donald Cleveland of UCSD and Isis Pharmaceuticals, Inc., of Carlsbad, CA are nearly “ready to go” with a clinical trial, perhaps
as soon as within 12 months, she observed.
“The critical thing to say here is that we really are edging
closer to human trials,” Dr. Corey-Bloom emphasized.
Dr. Cleveland, UCSD’s Ludwig Institute, and Isis will be
honored at HDSA-San Diego’s 12th Annual Celebration of Hope Gala on
November 16, 2012.
In the coming weeks, I will report in detail on the UC San
Diego/Isis project, which is mainly underwritten by the CHDI Foundation, Inc.,
the multi-million-dollar, non-profit biomedical research foundation dedicated
exclusively to accelerating Huntington’s drug discovery and development.

The shock of HD’s
reality
Having tested positive for HD in 1999 and watched my mother
succumb to the disease in 2006, I was thrilled to hear the news about the Isis
ASO trial.
I have tracked the progress of the project since early 2008,
shortly after the start of the CHDI-Isis collaboration (click here to read more).
Isis had first estimated that a clinical trial could start
in late 2010. As with many scientific endeavors, delays have occurred. Now that
a trial could realistically begin next year, I can once again fantasize about
living free of this scourge that robbed my beloved mother of her ability to
walk, talk, eat, and care for herself, leaving her a mere shadow of herself.
The support group meeting proved especially poignant for me
because I had not attended for a number of months. After a summer break from my
usual intense focus on HD, I once again confronted the reality of my own future
in the faces of the HD-affected individuals I saw at the meeting.
Seeing these disabled individuals shocked me into renewing
the fight to save them – and myself.
At 52, I am now at mother’s age of onset. Once again, I felt
extremely lucky to have avoided the noticeable, classic symptoms of HD.
Imagining a healthy
future
I have attended Dr. Corey-Bloom’s updates for about ten
years. Each time, she manages to provide clearer and more comprehensive
information.
Squeezing literally dozens of research developments into an
hour-long talk and making it understandable for a general audience is no small
challenge. As I told her afterwards, “You just get better every year!”
This year’s update especially served like a salve to calm my
worries, which had heightened considerably after hugging one HD-affected friend
who seemed to have declined since I last saw her a few months ago.
As Dr. Corey-Bloom spoke, I imagined this HD sister becoming
healthy again and happily growing old with her family.
