Biosimilar candidates referencing Prolia® and XGEVA®

Builds on first year success of Amneal’s initial three biosimilar launches

Expands existing biosimilar partnership with mAbxience

BRIDGEWATER, NJ, USA I October 12, 2023 I Amneal Pharmaceuticals, Inc. (NYSE: AMRX) (“Amneal” or the “Company”) today announced the addition of two denosumab biosimilars referencing both Prolia® and XGEVA® to its biosimilar pipeline.

Denosumab is a monoclonal antibody drug that inhibits bone reabsorption. It is indicated for two major categories of therapy: bone metastasis from various forms of cancer and prevention of bone pain and fractures, including osteoporosis-related injuries.

The two denosumab products are being developed by mAbxience, a global biotech company with over a decade of experience in the development, manufacture, and commercialization of biopharmaceuticals. Under the terms of the agreement, mAbxience will fully develop the biosimilar molecule and manufacture it in its state-of-the-art, Good Manufacturing Practice (GMP)-approved facilities, while Amneal will guide the product through regulatory approval and have exclusive commercialization rights in the United States. Amneal and mAbxience also currently partner on ALYMSYS®, a bevacizumab biosimilar.

“Our goal is to be a top five player in the U.S. biosimilar space, similar to our leadership position in U.S. retail generics. Biosimilars represent the next wave of affordable medicines and these new product opportunities are aligned with our strategy to provide high quality, essential therapies,” said Harsher Singh, Senior Vice President, Amneal Biosciences. “Our first three commercial U.S. biosimilars are doing very well as our excellent commercial team drives uptake in these competitive categories. We are pleased to partner again with mAbxience on these next two biosimilar candidates, which deepens our pipeline and expands our presence in oncology.”

“We are thrilled to strengthen our partnership with Amneal through this second agreement, marking a significant step forward in our shared mission to enhance global health. This collaboration will bring two world-class biosimilars for the treatment of bone diseases and oncology to patients across the U.S., reinforcing our commitment to ensuring worldwide access to high-quality, life-enhancing treatments. Together with Amneal, we continue to make strides in offering affordable and accessible healthcare solutions, contributing positively to public health and solidifying our presence in the global biosimilar space,” said Emmanuelle Lepine, Chief Executive Officer, mAbxience.

According to IQVIA®, U.S. annual sales for Prolia® and XGEVA® for the 12 months ended August 2023 were approximately $4.4 billion.

The financial terms of the transaction were not disclosed, and any incremental expenses associated with these products are contemplated within Amneal’s guidance.
