EC Grants Marketing Authorisation For Puma Biotechnology's NERLYNX

(RTTNews) - Puma Biotechnology Inc. (PBYI) said that the European Commission has granted marketing authorisation for NERLYNX or neratinib for the extended adjuvant treatment of adult patients with early stage hormone receptor positive HER2-overexpressed/amplified breast cancer and who are less than one year from the completion of prior adjuvant trastuzumab based therapy.

EC approval was based on the Phase III ExteNET trial, a multicenter, randomized, double-blind, placebo-controlled trial of neratinib following adjuvant trastuzumab treatment. Patients (n=2,840) with early stage HER2-positive breast cancer and within two years of completing adjuvant trastuzumab were randomized to receive either neratinib (n=1420) or placebo (n=1420) for one year.

The approval of NERLYNX by the European Commission follows the positive opinion issued by the Committee for Medicinal Products for Human Use of the European Medicines Agency in June 2018.

Neratinib was approved by the U.S. Food and Drug Administration (FDA) in July 2017 for the extended adjuvant treatment of adult patients with early stage HER2-positive breast cancer following adjuvant trastuzumab-based therapy, and is marketed in the United States as NERLYNX (neratinib) tablets.
