Alcon Commences Phase 2 Clinical Trial of NovaBay`s NVC-422 for Viral Conjunctivitis

EMERYVILLE, Calif. & HUENENBERG, Switzerland--(Business Wire)--
Alcon, Inc. (NYSE: ACL) and its partner, NovaBay Pharmaceuticals, Inc.
(NYSE-AMEX: NBY), announced today that Alcon has begun treating patients in a
Phase 2 clinical trial of NovaBay`s patented lead Aganocide® compound, NVC-422,
for viral conjunctivitis, a type of "pink eye." Conjunctivitis is a pervasive
and painful condition that affects both adults and children, leading to more
than four million doctor and emergency room visits in the United States each
year.

NovaBay has a licensing and research collaboration agreement with Alcon, the
world`s leading eye care company, for use of its Aganocide® compounds in the
eye, ear and sinus, and in contact lens solutions.

Developed by NovaBay to mimic the body`s defense against infection, Aganocides®
are proprietary synthetic analogs of the same molecules used by white blood
cells to destroy harmful microbes in the body, such as viruses and bacteria.
Because of their natural mechanism of action, NovaBay believes that Aganocide®
compounds have a low potential for generating microbial resistance, offering a
potential solution to the problem of rising resistance of microbes to
traditional antibiotics.

The Phase 2 viral conjunctivitis study follows a recently completed Phase 1
trial in which safety and tolerability were successfully demonstrated in 120
healthy volunteers with no reported serious adverse events.

"We are pleased to be entering mid-stage clinical testing for viral
conjunctivitis," said Ron Najafi, Ph.D., chairman and chief executive officer of
NovaBay. "This is the first step in the ophthalmic clinical development program
for NVC-422, which has the immediate goal of developing the first effective
product to address viral conjunctivitis for which there are limited treatment
options."

The Phase 2 multi-center, randomized, placebo-controlled trial is designed to
determine the safety and efficacy of NVC-422 in people with viral
conjunctivitis. The study calls for enrolling approximately 250 patients at more
than 30 medical centers, mostly in the United States.

"This study is an important step forward with the clinical program for this
potentially dual-acting therapy to address the multiple causes of
conjunctivitis. Dual action against viral and bacterial conjunctivitis is
important because when an infection is diagnosed it is difficult, time-consuming
and expensive to determine the underlying cause of the infection and treat it
properly," said Dr. Sabri Markabi, M.D., Alcon`s senior vice president of
research and development and chief medical officer.

About Conjunctivitis

Conjunctivitis, which can result from either viral or bacterial infection, is an
inflammation of the thin, clear tissue that covers the white part of the eye and
forms the inside lining of the eyelid. The viral disease is principally caused
by adenoviruses, but also can be caused by other viruses, such as enterovirus.
There is no specific treatment for adenoviral conjunctivitis, which can take up
to three weeks or longer to clear on its own. Bacterial conjunctivitis is caused
by a variety of bacteria and is largely treated with topically applied
antibiotic eye drops. Regular innovation to develop newer antibiotics is
required because over time antibiotics may encounter increasing bacterial
resistance.

About Aganocide® Compounds

The Aganocide® compounds are novel, proprietary, synthetic N-chlorinated
antimicrobial molecules specifically developed by NovaBay to mimic the body`s
natural defense against infection. The Aganocide® compounds maintain the
biological activities while improving the stability of naturally occurring
N-chlorinated antimicrobial molecules. These highly differentiated compounds may
deliver the same or better efficacy than currently used antibiotics without
contributing to the growing rise of antibiotic-resistant bacterial strains. In
preclinical testing, the Aganocide® compounds have been shown to be highly
effective against bacteria, viruses and fungi. They also have been demonstrated
to be effective against bacteria in biofilms, which render most antibiotics
ineffective. Aganocides have a broad therapeutic index while providing a high
degree of potency, good tolerability as well as dosing versatility and
flexibility.

antimicrobial molecules generated within white blood cells to treat and prevent
a wide range of infections without causing bacterial resistance. NovaBay has
internal development programs aimed at addressing hospital and respiratory
infections. The company has a licensing and research collaboration agreement
with Alcon, Inc. for use of its Aganocide® compounds to treat eye, ear and sinus
infections as well as in contact lens care solutions. NovaBay has also entered
into an agreement with Galderma S.A. to develop and commercialize Aganocides in
acne, impetigo and other dermatological indications. NovaBay® and Aganocide® are
