MONTREAL, Nov. 26, 2012 /PRNewswire/ --Valeant Pharmaceuticals International,
Inc. (NYSE: VRX and TSX: VRX) announced today that the Journal of the American
Academy of Dermatology has published the positive results from our two
pivotal, international, multicenter, randomized, double-blind,
vehicle-controlled studies that were conducted in 1,655 subjects with
onychomycosis. Onychomycosis is a common nail infection caused predominantly
by dermatophyte fungi, resulting in nail destruction and deformity. The only
approved topical treatments are lacquers with very limited efficacy. Oral
treatments, while more efficacious, are limited by drug interactions and
numerous safety concerns including the potential for acute liver injury.
Valeant investigated the safety and efficacy of efinaconazole 10% topical
solution (efinaconazole), the first triazole antifungal agent developed for
distal lateral subungual onychomycosis (DLSO).

The study's primary endpoint was stringently defined as the complete cure rate
at Week 52, which means that the target nail showed no clinical involvement
and no evidence of fungus present by both KOH testing and a negative fungal
culture. In Study 1, 17.8% of subjects treated with efinaconazole were
completely cured, as compared to only 3.3% of subjects treated with vehicle
and in Study 2, 15.2% of subjects treated with efinaconazole were completely
cured, as compared to only 5.5% of subjects treated with vehicle. Using the
secondary endpoint of complete or almost complete cure, defined as< 5%
clinical involvement and 100% mycologic cure, the success rates for
efinaconazole increased to 26.4% and 23.4%, respectively. The adverse events
that were reported were generally mild and transient and were similar between
subjects treated with efinaconazole solution 10% and vehicle.

"We are pleased to share the positive results from the two Phase III studies
of efinaconazole with the publication by a leading dermatology journal,"
stated J. Michael Pearson, chairman and chief executive officer. "While oral
treatment of onychomycosis has been the standard of care, drug interactions
and risk of acute liver injury may limit their use especially in older adults
where disease is most prevalent, those on multiple drug regimens, or for
patients or doctors who prefer topical therapies. As no new onychomycosis
treatments have been introduced for over 10 years, we believe in the authors'
conclusion that this may be the first topical treatment option for DLSO that
can be considered a viable alternative to oral treatments."

"This is a very exciting time for patients with the pending launch of the
first new topical anti-fungal treatment approved in more than a decade," said
Boni Elewski, MD Professor of Dermatology, University of Alabama.
"Onychomycosis is a common infection that, left untreated, can later appear
not only on other toes and fingers, but also on friends and family, too. It is
estimated that one in ten Americans suffer from onychomycosis, which causes
the nail to thicken and can be quite painful, making this condition more than
just a cosmetic problem. Furthermore, as some research indicates that up to
half of patients over the age of 70 suffer from this progressive disease. An
effective topical therapy like efinaconazole is a logical treatment option to
avoid drug interactions and systemic side effects, as these patients
undoubtedly take other oral medications."

Trial Design

The two large, international, multicenter, randomized, double-blind,
vehicle-controlled studies were conducted in subjects with onychomycosis
affecting at least one great toenail. The toenail was required to have at
least 20-50% of clinical involvement. Study 1 had 870 subjects and Study 2
had 785. They were randomized in a 3:1 ratio to efinaconazole topical solution
10% or to vehicle. Treatment was applied once-daily for 48 weeks, with
post-treatment follow-up occurring at Week 52. Debridement was not performed
in the studies.

The primary endpoint was stringently defined as the complete cure rate at Week
52, which means that the target nail showed no clinical involvement and no
evidence of fungus present by both KOH testing and by a negative fungal
culture.

In both studies, the primary endpoint of complete cure was statistically
significant (P < .001) in favor of efinaconazole topical solution 10%. In
Study 1, 17.8% of subjects treated with efinaconazole were completely cured
compared to only 3.3% of subjects treated with vehicle. In Study 2, 15.2% of
subjects treated with efinaconazole were completely cured compared to only
5.5% of subjects treated with vehicle. Although no head-to-head studies have
been conducted, these results are comparable to that reported with oral
treatment of onychomycosis.

Both studies also found that mycologic cure rates were also statistically
significant (P < .001) in favor of efinaconazole topical solution 10%. In
Study 1, 55.2% of subjects treated with efinaconazole demonstrated mycologic
cure compared to only 16.8% of subjects treated with vehicle. In Study 2,
53.4% of subjects treated with efinaconazole demonstrated mycologic cure
compared to only 16.9% of subjects treated with vehicle. Given that healthy
toenails can take 78 weeks to grow completely, it is not surprising that
mycologic cure rates are greater than complete cure rates. In addition, more
patients treated with efinaconazole (Study 1: 26.4% and Study 2: 23.4%)
achieved a complete or almost complete cure (<5% clinical involvement and
mycologic cure) compared with vehicle (Study 1: 7.0% and Study 2: 7.5%; both P
<.001).

The adverse events that were reported were generally mild and transient and
were similar between subjects treated with efinaconazole solution 10% and
vehicle. Local site reactions were infrequently reported (e.g., dermatitis),
and appeared to be more likely to occur with efinaconazole treatment (2%).
