Puma Biotechnology and Medison Pharma Enter into Exclusive Licensing Agreement to Commercialize NERLYNX® (neratinib) in Israel

LOS ANGELES--()--Puma Biotechnology, Inc. (Nasdaq: PBYI), a biopharmaceutical company, and Medison Pharma Ltd, Israel's leading commercial partner for innovative pharmaceuticals, have entered into an exclusive agreement under which Medison will commercialize NERLYNX® (neratinib) in Israel.

NERLYNX is not approved currently for commercialization outside of the United States. Medison will be responsible for seeking the requisite regulatory approval and, once approved, for commercializing NERLYNX in Israel. Puma will receive upfront and milestone payments throughout the term of this agreement, as well as significant double digit royalties on NERLYNX sales in Israel.

“Our new agreement with Medison demonstrates our commitment to bringing NERLYNX to patients around the world while continuing to focus our commercial resources on the U.S. market,” stated Alan H. Auerbach, Chief Executive Officer and President of Puma. “We are confident this new partnership will help patients in Israel access NERLYNX at the earliest opportunity.”

“We are excited about the opportunity to provide this therapy to women in our region. We plan to expedite access to NERLYNX via an early access program. In tandem, we plan to file for marketing authorization with the Israeli Ministry of Health, and expect to receive regulatory approval for NERLYNX in Israel during the first half of 2019,” said Meir Jakobsohn, Chief Executive Officer and Founder of Medison Pharma. “NERLYNX is highly complementary to our comprehensive portfolio, and will further strengthen Medison's lead in the Israeli oncology market.”

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.

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.

IMPORTANT SAFETY INFORMATION

NERLYNX ® (neratinib) tablets, for oral use

INDICATIONS AND USAGE: NERLYNX is a kinase inhibitor indicated for the extended adjuvant treatment of adult patients with early-stage HER2 overexpressed/amplified breast cancer, to follow adjuvant trastuzumab-based therapy.
