GlaxoSmithKline and Ann Arbor-based NanoBio Corporation announced today that
they have signed an exclusive over-the-counter licensing agreement for NanoBio's
unique nanoemulsion treatment for cold sores in the United States and Canada.

James R. Baker, Jr., M.D., director of the Michigan
Nanotechnology Institute for Medicine and Biological Sciences at the University
of Michigan Medical School, developed nanoemulsions in the 1990s at U-M
and founded NanoBio Corporation to further develop and commercialize the technology.
The nanoemulsion technology is patented by U-M and licensed to NanoBio Corporation.
Dr. Baker serves as CEO of NanoBio Corporation, where he holds a financial interest.
At U-M, he also is the Ruth Dow Doan Professor of Internal Medicine and allergy
"For the university, this agreement between NanoBio and GlaxoSmithKline
demonstrates the value of our technology and fulfills our goal of getting the
benefits of our research deployed broadly to the general public," says
Ken Nisbet, executive director of the U-M Office of Technology Transfer.
"We're very proud of the accomplishments of Dr. Baker and the entire NanoBio
Under the new agreement, New Jersey-based GlaxoSmithKline will pay NanoBio
an up-front fee of $14.5 million for licensing rights for the nanoemulsion product
called NB-001. NanoBio is eligible to receive additional milestone payments
of up to $40 million plus high single-digit royalties on future sales.
Nanoemulsions are superfine mixtures of soybean oil and water, stabilized by
surfactants and blended at very high speeds so that the resulting droplets are
less than 400 nanometers in diameter. Nanoemulsion droplets fuse with a microbe's
outer membrane, disrupt the membrane and kill the organism.
Baker believes that the GlaxoSmithKline-NanoBio partnership will "enable
the development and commercialization of NB-001 to its fullest potential and
validates the promise of our proprietary platform technology, and its potential
use in a wide range of dermatological and anti-infective applications."
NB-001 is the first nanoemulsion therapeutic to complete successful phase 2
clinical trials and will enter phase 3 testing within the next six months. NanoBio
is developing other nanoemulsion-based therapies for a range of diseases including
fungal infections, acne and molluscum contagiosum.
Cold sores, caused by the virus herpes labialis, affect about one-fifth of
adults in the United States. NB001 will add to GSK's Abreva? line of over-the-counter
medications for cold sores.
