Today, David Bearss is chief executive officer of Lehi-based biotech firm Tolero
Pharmaceuticals, whose team of scientists is conducting clinical trials on a
drug that has shown promise in treating acute myeloid leukemia, or AML.
According
to the American Cancer Society, AML is a blood disease that starts in the bone
marrow and in most cases quickly moves into the blood and sometimes can spread
to other parts of the body.
There
have been few new therapies for acute myeloid leukemia over the years, Bearss
said, and his company's research has been able to identify cells that can
target specific markers of AML.
"We're
trying to treat cells at a cellular and molecular level," he said.
The
company's lead drug candidate, alvocidib, is in midstage development. It can be
considered the “treatment of last resort” to help AML patients when other
treatments fail, Bearss said.
Tolero
was acquired by Sumitomo Dainippon Pharma, a large Japanese pharmaceutical
company, in December 2016.
Scientists
at Tolero discovered in its clinical trials that their drug appears to be
effective in patients with AML.
"What
is does is targets a pathway that cancers use to survive," explained
Bearss, who holds a doctorate in cell and structural biology from the
University of Texas Health Sciences Center at San Antonio and a bachelor's
degree from BYU.
"Our
body has ways to get rid of things that are going wrong. One of the things that
cancer cells have figured out is how to not die. Cancer cells have an inherent
ability to (survive)," he said.
Researchers
are working to determine the specific pathway AML cells are taking in the body
so they can develop a treatment that will target that specific pathway and help
patients with that particular biomarker cell in their individual cancer
profile, Bearss said.
Alvocidib
is currently being investigated in the second stage of a clinical study for AML
patients with a specific biomarker in the U.S., and a new drug application is
expected to be submitted to the U.S. Food and Drug Administration next year, he
explained.
Currently,
survival rates for AML patients are about 25 percent over five years, Bearss
said. He's hoping the company's team of scientists can increase that rate
significantly with their targeted cell approach.

F.D.A. Will Allow 23andMe to Sell Genetic Tests for Disease Risk to Consumers
For
the first time, the Food and Drug Administration said it would
allow a company to sell genetic tests for disease risk directly to consumers,
providing people with information about the likelihood that they could develop
various conditions, including Parkinson’s and Alzheimer’s.
The
move on Thursday is a turnaround for the agency, which had imposed a moratorium
in 2013 on disease tests sold by the company, 23andMe, which is based in
Mountain View, Calif. The decision is expected to open the floodgates for more
direct-to-consumer tests for disease risks, drawing a road map for other
companies to do the same thing.
23andMe
will now be reporting telltale markers for 10 diseases. Most, like factor XI deficiency, a blood clotting
disorder, and Gaucher disease type 1, an organ and tissue
illness, and celiac disease are rare. Anyone who buys
the $199 Ancestry and Health test from the company will automatically learn if
they have mutations increasing their risk for those diseases.
Risk
genes for Alzheimer’s and Parkinson’s are treated separately. Customers will
have to specifically say that they want that information. The company’s website
offers links to genetic counselors for those who are weighing whether to be
tested. If they want those results they will be included at no extra charge,
though patients have to pay for the counseling separately.
Until
now, the only way for people to get such genetic tests was to see a medical
professional who would order a test and later deliver the results to patients.
Often, patients were required to see a genetic counselor before getting a test.
The
process for customers is simple. A customer spits into a tube and then mails it
to 23andMe. The company’s lab extracts DNA from the saliva cells and tests it
with probes that find genetic markers using a special chip for
genotyping. In about six to eight weeks the company sends the customer an email
saying the results are in. By logging onto an online account, the customer can
see the report and its interpretation. It will include not just the genes for
disease risk, but also reports of ancestry and results on things like how much
the person is likely to weigh and whether alcohol will elicit flushing of the
face, shoulders and neck, or even the entire body.
