LOS ANGELES--(BUSINESS WIRE)--Puma Biotechnology, Inc. (Nasdaq: PBYI) announced that the Committee for
Medicinal Products for Human Use (CHMP) of the European Medicines Agency
(EMA) has adopted a positive trend vote recommending the approval of the
Marketing Authorisation Application (MAA) for neratinib for the extended
adjuvant treatment of early stage HER2-positive hormone receptor
positive breast cancer. Today’s decision follows a reexamination of the
negative opinion announced by the CHMP at its formal meeting with the
Company to discuss the MAA on February 23, 2018. The CHMP communicated
its intention to hold a final vote at its next meeting.
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.
