Item 8.01

Other Events.

On November 30, 2015, Puma Biotechnology, Inc. (the “Company”) announced that based on its recent meeting with the European Medicines Agency (“EMA”), the Company plans to submit a Marketing Authorisation Application (“MAA”) for the approval of neratinib for the extended adjuvant treatment of HER2-positive early stage breast cancer in patients who have previously been treated with a trastuzumab-containing regimen in the first half of 2016.

The Company recently conducted an MAA pre-submission meeting with the EMA. The purpose of this meeting was to provide the EMA with data from neratinib’s non-clinical and clinical development programs that will form the basis of MAA sections for EMA review and approval. The data discussed with the EMA included non-clinical data (pharmacology, toxicology and carcinogenicity) and clinical trial data including the data from the Phase III trial of neratinib in the extended adjuvant treatment of HER2-positive early stage breast cancer (ExteNET trial). Upon review of this material, the EMA assessed that there were no critical concerns that would prevent the Company from submitting a complete MAA for European centralized review in support of neratinib for the extended adjuvant treatment of HER2-positive early stage breast cancer in patients who have previously been treated with a trastuzumab-containing regimen.
