Puma Biotechnology, Inc. announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has communicated a negative trend vote after meeting with the company to discuss the Marketing Authorisation Application (MAA) for neratinib for the extended adjuvant treatment of early stage HER2-positive breast cancer. A negative trend vote means it is unlikely that CHMP will provide a positive opinion related to the Company’s MAA at the formal CHMP decision vote scheduled in February 2018, and that additional steps would need to be taken to gain marketing approval in Europe. CHMP indicated that, in its opinion, the benefit risk assessment is negative as the study results are based on evidence from a single pivotal trial and the 2- and 5-year invasive disease free survival (iDFS) benefits observed to-date may lack sufficient clinical relevance. CHMP’s opinion was based on the 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. About HER2-Positive Breast Cancer: Approximately 20% to 25% of breast cancer tumors over-express the HER2 protein. HER2-positive breast cancer is often more aggressive than other types of breast cancer, increasing the risk of disease progression and death. Although research has shown that trastuzumab can reduce the risk of early stage HER2-positive breast cancer returning after surgery, up to 25% of patients treated with trastuzumab experience recurrence.
Puma Biotechnology, Inc. is a biopharmaceutical company. The Company is focused on the development and commercialization of products to enhance cancer care. The Company's lead product is NERLYNX, an oral version of neratinib, for the treatment of HER2-positive breast cancer. Neratinib is a potent irreversible tyrosine kinase inhibitor (TKI) that blocks signal transduction through the epidermal growth factor receptors, HER1, HER2 and HER4 It also engaged in the development and commercialization of, alisertib. Alisertib is a selective, small molecule inhibitor of aurora kinase A that is designed to disrupt mitosis leading to apoptosis of rapidly proliferating tumor cells that are dependent on aurora kinase A. Its neratinib has clinical application in the treatment of several other cancers as well, including other tumor types that over-express or have a mutation in HER2 or epidermal growth factor receptor (EGFR), such as breast cancer, cervical cancer, lung cancer, or other solid tumors.
