After
a budgetary crisis that practically eliminated support to HD scientists in
recent years, the Huntington’s Disease Society of America (HDSA) has committed
itself to reestablishing a program of research projects critical for developing
effective treatments.
In
a September 28 e-mail message to “HDSA friends,” HDSA CEO Louise Vetter
announced the hiring of George Yohrling, Ph.D., to fill the new position of
Director of Medical & Scientific Affairs.
“In
the past we have relied upon the volunteer support and consultation of
physicians and scientists,” Vetter explained in an interview in San Diego on
November 16. “We will continue to do so. But based on what the pace of HD
research is right now and our vision to have a new research program, we felt it
was the right time to bring that expertise in-house.”
Dr.
Yohrling, a molecular neuroscientist, has worked in the HD field since 2000.
“His
first job was with an HDSA Coalition for the Cure lab,” Vetter said. “He was
funded with an HDSA grant, and he has continued to stay in the field.... He has
real expertise in HD, which is incredibly important. His primary task is to
launch a new research program for the organization.”
The
hire marks the first step in fulfilling a series of goals outlined in HDSA’s
first-ever strategic plan,
formulated after broad consultation with the HD community in 2011 and 2012, and
launched by Vetter at the annual HDSA convention last June (click here to read
a report on the drafting of the plan).
In
response to recent criticisms of HDSA because of the drastic decline in
research support (click here to read more), Vetter stated that HDSA is working
“to have the most impact for the most people and help set the course for the
best care and the best treatments as soon as possible.”

Avoiding repetition
In
crafting the new research program, HDSA planners took into account the
organization’s limited budget (about $8.5 million annually) and strived to
avoid duplicating efforts by other HD initiatives focused strictly on research,
Vetter added.
Both
Vetter and Dr. Yohrling emphasized that the new research program will focus on
HD research in humans and human cells. This contrasts sharply with – but also
necessarily complements – the research conducted on animals.
Focusing on humans
“We’re
calling it ‘Human HD Biology Project,’” Dr. Yohrling said in a November 26
interview. “All of the observations will be from human HD patients, and not from
a worm or mouse or fly. There’ll be no arguing about the physiological relevance
of the data we will acquire.”
Dr.
Yorhling explained that the project will function like a post-doctoral or
clinical fellowship program. Young scientists will partner with the directors
of HDSA’s 21 Centers of Excellence for Family Services and Research, which see
patients and other HD family members on a regular basis. It replaces the Coalition
for the Cure grant program, which ceased to exist with the onset of the budget
crisis.

The
new researchers will focus on tasks such as the search for human biomarkers –
specific signs of the disease within bodily fluids or tissues or the brain, for
example – that will become crucial for measuring the effects of potential
remedies.
“These
are studies, not clinical trials, but their outcome could and should help
support, drive, and steer clinical trials,” Dr. Yohrling explained, adding that
he is currently recruiting HD specialists to serve on the program’s advisory
committee, which will review the applications from researchers.
Grants
will be relatively modest, Dr. Yorhling indicated. “These won’t be $250,000
jobs,” he said. However, because of the clear emphasis on non-redundancy,
“hopefully we’ll get a big bang for our buck,” he added.
HDSA
has already raised funds to kick off the project, Dr. Yorhling said, although
both he and CEO Vetter recognized the need to increase fundraising to expand
support for research.
HDSA
hopes to issue its first call for proposals in early 2013, Dr. Yohrling said.
HDSA
also will continue to support an important consortium of HD stem cell
researchers, he noted.
A pivotal player
Dr.
Yohrling’s diverse experience in HD research makes him a pivotal player in the
search for treatments.
After
receiving his Ph.D. in pharmacology from Wake Forest University in 2000, he
became the very first post-doctoral researcher in the lab of Jang-Ho Cha, M.D.,
Ph.D., at Harvard Medical School/Massachusetts General Hospital. (Dr. Cha is a
member of the HDSA Board of Trustees and will chair the HD Human Biology
Project Advisory committee.) During his two years under Dr. Cha, he “got to see
and interact with HD firsthand.”
“Any
human being with a soul in their body” would be motivated to help, Dr. Yohrling
recalls of his initial, serendipitous contact with Dr. Cha and the HD team
while in Boston searching for a post-doctoral position. “I was hooked. I felt
it was my calling.”
Under
Dr. Cha, Dr. Yohrling also received an HDF grant.
Dr.
Yorhling spent the next five years conducting Alzeimer’s disease research at
the pharmaceutical giant Johnson & Johnson, followed by two years at
Galleon Pharmaceuticals, Inc., researching respiratory conditions.
In
2009 Dr. Yohrling joined CHDI, which he described as a “dream” of an
opportunity to focus fully on HD research in a large, resource-rich
organization. There he served as director of target assessment and then
director of systems biology-pathway assessment. Working with firms and leading
HD scientists, he managed millions of dollars in research contracts. He also
led the development of HD Research Crossroads,
an online repository of HD-relevant drug target validation data.
Impacting patients with ‘all hands
on deck’
CHDI
was “more a behind-the-scenes operation,” Dr. Yohrling observed. “HDSA is more
of a grassroots, family-oriented foundation. The opportunity to get back to
that, while also getting involved in human biology research, was an opportunity
too good to ignore.”
Responding
to the argument that HDSA should let others concentrate on research while
putting funds strictly into social services, Dr. Yohrling observed that the
HDSA board and HD families want the organization “back involved in research and
not to leave it up to the other entities like CHDI, HDF, and the government,”
although his key responsibilities will include maintaining “an open line of
communications” with those and other HD research organizations.
“We’re really glad to have someone like George working
at HDSA,” said Robi Blumenstein, the president of CHDI Management, Inc., which
carries out the day-to-day tasks of CHDI’s mission. “It just furthers our
ability to collaborate.”
“I think that HDSA is well-positioned with their
centers of excellence around the country,” Dr. Yohrling continued. “This is an
incredible resource. It’s a huge benefit that HDSA has over other foundations
or organizations, this access and close connection to the patients. A research
program, although it might be limited initially, if the money is use properly
and thoughtfully, can have a huge impact on the lives of patients.”
“We need all hands on deck,” said Vetter, adding
that everybody in the HD community can take small but important steps to help
the cause by keeping in touch with attending physicians, learning about HD
research, and participating in clinical trials and research studies. “As we
look at the dawn of a new time of HD therapeutic development, the only way
those drugs are going to come to market is if people get involved. Getting
involved is the most important thing
that the HD community can do right now.”
