  Application to the FDA for Tavaborole

Business Wire

PALO ALTO, Calif. -- July 29, 2013

Anacor Pharmaceuticals (NASDAQ:ANAC) announced today that on July 26, 2013 it
submitted its New Drug Application (NDA) to the U.S. Food and Drug
Administration (FDA) for tavaborole, its drug candidate for the topical
treatment of onychomycosis. Onychomycosis is a fungal infection of the nail
and nail bed that affects approximately 35 million people in the United
States.

“The submission of the NDA is a significant milestone for Anacor,” said David
Perry, Anacor’s Chief Executive Officer. “Anacor was founded eleven years ago
based on the promise of boron chemistry. Tavaborole is the first drug in our
pipeline to reach this important milestone, and I’d like to acknowledge and
thank the entire Anacor team for their hard work, dedication and persistence.”

Anacor announced earlier this year that tavaborole achieved statistically
significant and clinically meaningful results on all primary and secondary
endpoints in two Phase 3 pivotal studies of tavaborole to treat onychomycosis
topically without concomitant debridement. The only currently FDA-approved
topical treatment for onychomycosis is approved with concomitant nail
debridement, and currently approved oral therapies have been associated with
rare but serious safety issues.

About Anacor Pharmaceuticals

Anacor is a biopharmaceutical company focused on discovering, developing and
commercializing novel small-molecule therapeutics derived from its boron
chemistry platform. Anacor has discovered eight compounds that are currently
in development. Its two lead product candidates are topically administered
dermatologic compounds — tavaborole, a topical antifungal for the treatment of
onychomycosis, and AN2728, a topical anti-inflammatory PDE-4 inhibitor for the
treatment of atopic dermatitis and psoriasis. In addition to its two lead
programs, Anacor has discovered three other wholly-owned clinical product
candidates — AN2718 and AN2898, which are backup compounds to tavaborole and
AN2728, respectively, and AN3365 an antibiotic for the treatment of infections
caused by Gram-negative bacteria. We have discovered three other compounds
that we have out-licensed for further development — two compounds for the
treatment of animal health indications that are licensed to Eli Lilly and
Company and AN5568, also referred to as SCYX-7158, for human African
trypanosomiasis (HAT, or sleeping sickness), which is licensed to Drugs for
Neglected Diseases initiative, or DNDi. We also have a pipeline of other
internally discovered topical and systemic boron-based compounds in
development. For more information, visit http://www.anacor.com.
