Pfizer expects to complete the acquisition in the third-quarter 2016.
Pfizer and Anacor Pharmaceuticals, has announced that they have entered into a definitive merger agreement under which Pfizer will acquire Anacor for $99.25 per Anacor share, in cash, for a total transaction value, net of cash, of approximately $5.2 billion, which assumes the conversion of Anacor's outstanding convertible notes.
The Boards of Directors of both companies have unanimously approved the transaction. Anacor's flagship asset, crisaborole, a differentiated non-steroidal topical PDE4 inhibitor with anti-inflammatory properties, is currently under review by the US FDA for the treatment of mild-to-moderate atopic dermatitis, commonly referred to as eczema.
"We believe the acquisition of Anacor represents an attractive opportunity to address a significant unmet medical need for a large patient population with mild-to-moderate atopic dermatitis, which currently has few safe topical treatments available," said Mr Albert Bourla, Group President of Pfizer's Global Innovative Pharma and Global Vaccines, Oncology and Consumer Healthcare Businesses. "Crisaborole is a differentiated asset with compelling clinical data that, if approved, has the potential to be an important first-line treatment option for these patients and the physicians who treat them."
In both of its Phase 3 pivotal studies, crisaborole achieved statistically significant results on all primary and secondary endpoints and in March 2016, the FDA accepted for review Anacor's New Drug Application seeking approval of crisaborole for the potential treatment of mild-to-moderate atopic dermatitis in children and adults. The Prescription Drug User Fee Act (PDUFA) goal date for the completion of the FDA's review is January 7, 2017. If approved, Pfizer believes peak year sales for crisaborole have the potential to reach or exceed $2.0 billion.
"Today marks the beginning of an exciting new chapter for Anacor, which we believe will deliver significant value to our shareholders," said Mr Paul L. Berns, Anacor's chairman and CEO. "We have a deep respect for Pfizer, and it is clear that they share our commitment to addressing the significant unmet medical needs in inflammatory disease. We are proud of the innovative company that our team has built and are confident that Pfizer will help accelerate Anacor's important mission given the strength of its global platform and resources."
