Puma Biotechnology, Inc. (Nasdaq: PBYI), a biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has scheduled the New Drug Application (NDA) for neratinib for discussion by the Oncologic Drugs Advisory Committee (ODAC) on May 24, 2017. Neratinib is an investigational therapy for the extended adjuvant treatment of early stage HER2-positive breast cancer that has previously been treated with a trastuzumab containing regimen.

ODAC is an independent panel of experts that evaluates data concerning the efficacy and safety of marketed and investigational products for use in the treatment of cancer and makes appropriate recommendations to the FDA. Although the FDA will consider the recommendation of the panel, the final decision regarding the approval of the product is made by the FDA solely, and the recommendations by the panel are non-binding.

Puma Biotechnology announced on September 20, 2016 that the FDA had accepted for filing the NDA for neratinib. The NDA for neratinib is based on results from both the Phase III ExteNET trial in extended adjuvant early stage HER2-positive breast cancer and the Phase II CONTROL trial in extended adjuvant early stage HER2-positive breast cancer.
