Builds on U.S. biosimilar portfolio of seven products with three commercial and four in pipeline

8^th biosimilar expands portfolio into allergy treatments, a new therapeutic area

Amneal Pharmaceuticals, Inc. (Nasdaq: AMRX) (“Amneal” or the “Company”) today announced the addition of omalizumab, referencing XOLAIR^®, to its biosimilar pipeline.

Omalizumab is a humanized monoclonal antibody which targets free immunoglobulin E (IgE). It is an injectable prescription drug used to treat a number of chronic conditions such as severe persistent allergic asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), food allergies, and chronic spontaneous urticaria. It is typically administered in a hospital or clinic setting. The biosimilar was developed by Kashiv BioSciences, LLC and is currently in a Phase III clinical trial, which began in the third quarter of 2023.

“We are excited to further grow our biosimilar pipeline with the addition of omalizumab and expand into a new therapeutic area beyond oncology. We are building on the strong success of our first commercial biosimilars. Amneal is committed to providing affordable biologic medicines which will increase access and choice to patients and providers, and drive cost savings to the U.S. healthcare system,” said Sean McGowan, Vice President, Biosimilars and Branded Oncology.

“We are pleased to partner with Amneal on our most advanced pipeline product, ADL018, a proposed biosimilar to XOLAIR^®. We are building on our highly productive partnership with the commercial success of RELEUKO^® and FYLNETRA^®, and advancement of additional peg-filgrastim programs. Kashiv is one of a few companies based in the United States to manufacture and receive marketing authorization of multiple biosimilars. By relentlessly focusing on quality and cost-effective development, Kashiv continues to build upon its strong track record of developing and manufacturing high-quality, affordable biosimilars to improve patients’ lives worldwide,” said Dr. Sandeep Gupta, Chief Executive Officer of Kashiv.

According to IQVIA^®, U.S. annual sales for XOLAIR^® for the 12 months ended April 2024 were approximately $3.2 billion. XOLAIR^® is a registered trademark of Novartis AG.

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