California’s $39 million bet on a new stem
cell therapy for diabetes today moved a notch ahead today with word that the
treatment's developer has received federal approval to begin a clinical trial.
“Very
encouraging news” was how the new president of the state stem cell agency, Randy Mills, described the
announcement by Viacyte, Inc.
“Exciting” was the word used by Jonathan
Thomas, chairman in a pressrelease from the California Institute of
Regenerative Medicine (CIRM), as the $3 billion agency is formally known.
CIRM began financing Viacyte six years ago.
The
go-ahead by the FDA was for an early stage trial aimed at testing safety and
preliminary efficacy for treatment for type 1 (juvenile) diabetes. While the
move is a good sign, only one out of any 10 potential therapies that begin a
trial emerges as a full-blown treatment. That statistic is for ordinary
treatments – not therapies based on human embryonic stem cells (hESC). No hESC
therapy has ever been commercialized, and they face unique regulatory and
financial obstacles.
CIRM’s
press release described the treatment like this:
“ViaCyte’s approach uses a thin plastic pouch, containing an immature form of pancreatic cells, to mimic the blood glucose regulating function of the pancreas. When the device is implanted under the skin these cells are designed to become insulin-producing and other cells needed to regulate blood glucose levels. It is believed that these cells will be able to sense when blood glucose is high, and then secrete insulin to restore it to a healthy level.”
In
addition to the news release, the stem cell agency ran a blog item on the announcement, which is useful, since there is more
than one audience for the news. The agency did not link to the press release
from Viacyte, which noted that the Juvenile
Diabetes Research Foundation also
supported the research.
Paul Laikind, president of Viacyte, said in his press release that he was “pleased” by the FDA action. That was the most ebullient word
in the company’s announcement, which focused on the more technical aspects of
the potential therapy.
In
news coverage, Bradley Fikes of
the San Diego U-T wrote that the company has said the treatment could serve as a “virtual cure” for
type 1 diabetes, which afflicts more than two million persons in the United
States.
