Newswise, August 22, 2016– The University of Alabama at
Birmingham, along other members of the Geroscience Network, has
published six manuscripts that map strategies for taking new drugs that target
processes underlying aging into clinical trials.
Researchers believe these agents hold promise for treating
multiple age-related diseases and disabilities. The articles appear today in
The Journals of Gerontology: Series A – Biological Sciences and Medical
Sciences.
The Geroscience Network, formed by Steven Austad, Ph.D.,
distinguished professor and chair ofUAB’s Department of Biology in the College of Arts and Sciences; James
Kirkland, M.D., Ph.D., director of the Mayo Clinic Robert and Arlene Kogod
Center on Aging; and Nir Barzilai, M.D., Albert Einstein College of Medicine,
consists of 18 academic aging centers, along with the participation of more
than 100 investigators from across the United States and Europe. The network is
funded by the National Institutes of Health.
“Aging is not just an abstract and intriguing biological
problem,” Austad said.
“It is the No. 1 cause of death and disability in today’s
world. Its threat is very significant, because aging is a major risk factor in
a host of other serious diseases and health issues.
The Geroscience Network seeks to combine research from a
number of institutions to address this ever-growing challenge.”
“Aging is the largest risk factor for most chronic diseases,
including stroke, heart disease, cancer, dementias, osteoporosis, arthritis,
diabetes, metabolic syndrome, blindness and frailty,” Kirkland said.
“Recent research suggests that aging may actually be a
modifiable risk factor. The goal of our network’s collaborative efforts is to
accelerate the pace of discovery in developing interventions to delay, prevent
or treat these conditions as a group, instead of one at a time.”
Austad is the senior author on the manuscript “Evaluating
Health Span in Preclinical Models of Aging and Disease: Guidelines, Challenges,
and Opportunities for Geroscience,” which assesses how research animals can be
best employed to guide the development of therapies that counteract aging
processes.
Kirkland is senior author on manuscripts that explore the
challenges of developing aging interventions:
•“Barriers to the Preclinical Development of Therapeutics That Target Aging Mechanisms”
•“Frameworks for Proof-of-Concept Clinical Trials of Interventions That Target Fundamental Aging Processes”
•“Barriers to the Preclinical Development of Therapeutics That Target Aging Mechanisms”
•“Frameworks for Proof-of-Concept Clinical Trials of Interventions That Target Fundamental Aging Processes”
The first manuscript summarizes discussions held at a 2014
Geroscience Network retreat.
While research efforts have successfully identified new drugs
that extend lifespan in animals, the authors discuss the need to develop a
consistent preclinical pipeline for drug development that focuses on best
practices for drug discovery, development of lead compounds, translational
preclinical biomarkers, funding and support for preclinical studies, and
integration between researchers and clinicians.
In the second manuscript, the researchers acknowledge that
aging therapies may hold “great promise” for enhancing the health of a wide
population, with clinical trials’ being a critical step for translating
therapies from animals into humans.
The manuscript is built on the outcomes of an international
meeting funded through the National Institutes of Health R24 Geroscience
Network.
The other manuscripts published are:
•“Strategies and Challenges in Clinical Trials Targeting Human Aging”
•“Resilience in Aging Mice”
•“Moving Geroscience Into Uncharted Waters”
•“Strategies and Challenges in Clinical Trials Targeting Human Aging”
•“Resilience in Aging Mice”
•“Moving Geroscience Into Uncharted Waters”
Felipe Sierra, Ph.D., of the National Institute on Aging and a
member of the Geroscience Network, describes the potential impact of aging
discoveries in his manuscript, “Moving Geroscience Into Uncharted Waters.”
Sierra said, “In addition to the direct health issues, it has
been calculated that care for the elderly currently accounts for 43 percent of
the total health care spending in the U.S., or approximately $1 trillion a
year, and this number is expected to rise as baby boomers reach retirement age.
“Reducing these costs is critical for the survival of society
as we know it, and a 2013 paper by Dana Goldman and colleagues calculated that
a modest increase in lifespan and health span (2.2 years) could reduce those
expenses by $7 trillion by 2050.”
“While significant work has already been accomplished, there
is much more to be done as we focus on translating findings into practice,”
Kirkland said.
“The Geroscience Network is a collaborative way to overcome
barriers and move us closer to our shared goal of increasing health span — the
healthy, independent years of life for the elderly.”
