Puma Biotechnology and Pierre Fabre Enter into Exclusive License Agreement to Develop and Commercialize NERLYNX® (neratinib) in Europe
LOS ANGELES, Calif. and CASTRES, France, April 1, 2019 – Puma Biotechnology, Inc. (Nasdaq: PBYI) and Pierre Fabre have entered into an exclusive license agreement under which Pierre Fabre will develop and commercialize NERLYNX® (neratinib) within Europe and part of Africa. In September 2018 the European Commission granted marketing authorization for NERLYNX® (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.
Pierre Fabre will have exclusive commercialization rights for NERLYNX in European countries excluding Russia and Ukraine, along with countries in North Africa and francophone countries of West Africa. Pierre Fabre will also be responsible of conducting additional clinical studies and leading regulatory activities in connection with the European Medicines Agency (EMA).
Under the terms of the agreement, Puma will receive an upfront payment of $60 million, as well as additional regulatory and commercial milestone payments totaling up to $345 million. In addition, Puma will receive significant double-digit royalties on NERLYNX sales throughout the territory covered by the license agreement between Puma and Pierre Fabre.
“Puma is committed to providing access to NERLYNX to patients around the world and soon physicians and patients in Europe will have commercial availability of NERLYNX,” stated Alan H. Auerbach, Chief Executive Officer and President of Puma.
“Pierre Fabre has a robust commercial and medical oncology infrastructure that we hope will lead to rapid commercial access to NERLYNX.” “We are thrilled to provide this new therapy to patients with HER2-positive breast cancer throughout Europe,” said Frederic Duchesne, Chief Executive Officer, Pierre Fabre Pharmaceuticals. “Pierre Fabre has developed a strong expertise and presence in the breast cancer treatment and the addition of NERLYNX to our historical oncology portfolio will allow us to strengthen our commercial presence. We anticipate providing access to NERLYNX to patients throughout Europe in 2019 and 2020, starting with Germany.”
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.
