Treatment for Atopic Dermatitis

Update: Eucrisa (crisaborole) Ointment Now FDA Approved - December 14, 2016

Anacor Pharmaceuticals Submits NDA to the FDA for Crisaborole Topical Ointment, 2% for the Treatment of Mild-to-Moderate Atopic Dermatitis

PALO ALTO, Calif., January 7, 2016 --(BUSINESS WIRE)-- Anacor Pharmaceuticals, Inc. (NASDAQ:ANAC) announced today that it has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) seeking approval of crisaborole topical ointment, 2%, a novel non-steroidal topical anti-inflammatory phosphodiesterase-4 (PDE-4) inhibitor in development for the potential treatment of mild-to-moderate atopic dermatitis in children and adults.

"The submission of the NDA for crisaborole topical ointment, 2% represents an important milestone for our atopic dermatitis development program, as we continue to leverage our boron chemistry platform to pursue innovative new therapies," said Paul L. Berns, Chairman and Chief Executive Officer of Anacor. "We believe there is a significant unmet medical need for a novel non-steroidal topical anti-inflammatory treatment option for the patients who are suffering with mild-to-moderate atopic dermatitis and we look forward to working with the FDA during its review of the crisaborole NDA."

In July 2015, Anacor announced the positive top-line results from its two Phase 3 pivotal studies of crisaborole. In each of the two Phase 3 pivotal studies, crisaborole achieved statistically significant results on all primary and secondary endpoints and demonstrated a safety profile consistent with previous studies. In October 2015, Anacor announced the top-line results from its long-term safety study, in which crisaborole was found to be well-tolerated and demonstrated a safety profile consistent with that seen in the Phase 3 pivotal studies when used intermittently for up to 12 months.

About Crisaborole Topical Ointment, 2%

Crisaborole topical ointment, 2%, is an investigational non-steroidal topical anti-inflammatory PDE-4 inhibitor in development for the potential treatment of mild-to-moderate atopic dermatitis. Crisaborole is a novel boron-containing small molecule and, although the specific mechanism of action is not yet completely defined, Anacor believes that crisaborole inhibits PDE-4 in target cells, which reduces the production of pro-inflammatory cytokines thought to cause the signs and symptoms of atopic dermatitis.

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's first approved drug, KERYDIN® (tavaborole) topical solution, 5%, is an oxaborole antifungal approved by the U.S. Food and Drug Administration in July 2014 for the topical treatment of onychomycosis of the toenails. In July 2014, Anacor entered into an exclusive agreement with Sandoz Inc., a Novartis company, pursuant to which PharmaDerm, the branded dermatology division of Sandoz, distributes and commercializes KERYDIN in the United States. In September 2014, PharmaDerm launched KERYDIN in the United States. Anacor's lead product development candidate is crisaborole topical ointment, 2%, a novel non-steroidal topical anti-inflammatory PDE-4 inhibitor in development for the potential treatment of mild-to-moderate atopic dermatitis and psoriasis. Beyond KERYDIN and crisaborole, Anacor has discovered three investigational compounds that it has out-licensed for further development. The first compound is licensed to Eli Lilly and Company for the potential treatment of an animal health indication. The second compound, AN5568, also referred to as SCYX-7158, is licensed to Drugs for Neglected Diseases initiative for the potential treatment of human African trypanosomiasis. The third compound is licensed to GlaxoSmithKline LLC for development in tuberculosis. Anacor also has a pipeline of other internally discovered topical and systemic boron-based compounds in early stages of research and development. These include AN3365, an investigational Gram-negative antibiotic, and certain other wholly-owned investigational product candidates. For more information, visit
