M.D., the study evaluated the efficacy and
safety of celecoxib as a chemopreventive
agent for actinic keratoses, which are pre-
program because of its effectiveness in pre-
clinical animal model breast cancer studies.
Most recently, Dr. Muccio and his team
have been working with the University of
Wisconsin, which has been conducting the
first stages of the phase I trials in humans. “So
far, they have found UAB-30 to show very lit-
tle toxicity and very favorable pharmacology,”
Dr. Muccio says. “The second part of their
trial will be a dose-escalation study to better
determine the toxicity level for patients.”
While the Wisconsin group is examin-
ing the effects of UAB-30 as a preventative
drug, their results will influence UAB-
30’s role in cancer treatment at the Cancer
Center. “Once they have determined the
drug’s toxicity, we will be using UAB-30 in
phase II trials as a treatment for breast can-
cer patients here at UAB,” says Dr. Muccio.
Those trials could begin as soon as fall 2011.
LEADINg thROUgh thE LABORAtORy
In 2009, UAB researchers announced the
discovery of a new and efficient method to
produce and study one of the cancer-causing
strains of human papillomavirus (hPV). Of
the more than 120 strains of hPV, 15 are
cancerous growths on the skin.
Celecoxib is in a class of NSAIDs called
COX-2 inhibitors. Currently, it is used to
relieve pain, tenderness, swelling and stiffness
caused by osteoarthritis, rheumatoid arthritis
and spinal arthritis. It also can be used off-
label to treat painful menstrual periods and
pain from other causes and is used to reduce
the number of colon and rectal polyps in
patients with familial adenomatous polyposis.
In animal models, Celebrex has inhib-
ited the development of ultraviolet-induced
pre-malignant skin papillomas, which are
thought to correspond to actinic keratoses.
The double-blind, placebo-controlled trial
followed 240 subjects ages 37 to 87 with
10 to 40 actinic keratoses at eight U.S. aca-
demic medical centers over an 11-month
period. At nine months after randomization,
there was no difference in the incidence of
new actinic keratoses developed between the
placebo group and those receiving celecoxib.
Compared with the placebo, celecoxib was
highly effective in preventing non-melanoma
skin cancers from developing in subjects
who had large numbers of actinic keratoses.
“While celecoxib was not effective in
preventing new actinic keratoses, the study
raises the possibility that the drug is effec-
tive in preventing cancer from developing
classified as high-risk because they often cause
cervical cancer. Two of those 15—known as
hPV 16 and hPV 18—cause approximately
two-thirds of all cervical cancers.
International hPV research experts
Louise Chow, Ph.D., and Thomas Broker,
Ph.D., both UAB professors of biochemistry
and molecular genetics, led a study that dis-
covered a laboratory process for producing
hPV 18, the culmination of more than 20
years of work.
Previously, scientists had been unable to
produce hPV 18 in a lab setting, making
it extremely difficult to study the virus and
its effects. The new method discovered by
Drs. Broker and Chow allows researchers to
reproduce the entire infection cycle of hPV
18 in primary human skin cells. By doing so,
this process could potentially unveil prom-
ising targets for drug design and antiviral
agents to treat existing hPV-18 infections as
well as other types of the virus.
A NEw stANDARD fOR hEAD AND NECk CANCER
Since 2000, Cancer Center researchers
have been studying the effects of combining
erbitux (cetuximab) with radiation for the
treatment of advanced head and neck cancer.
In 2010, the results of a decade’s work were
published in The Lancet Oncology—and the
findings were significant.
Researchers found that combining the
two treatments improved the five-year sur-
vival of patients with advanced head and
neck cancer by 10 percentage points, from 36
percent still alive at five years to 46 percent.
The Cancer Center was a leader in the devel-
opment and approval of erbitux, a mono-
clonal antibody that attaches to and blocks
