Recommended for Approval for the Same Indications as Herceptin® (Trastuzumab)

Positive Opinion for ABP 980 is Supported by Phase 3 Data in Patients With HER2-Postive Early Breast Cancer

THOUSAND OAKS, CA, USA I March 23, 2018 I Amgen (NASDAQ: AMGN) and Allergan plc. (NYSE: AGN) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion for the marketing authorization of ABP 980, a biosimilar to Herceptin® (trastuzumab). ABP 980 has been recommended for approval for the treatment of the same three types of cancer as Herceptin is approved for in the European Union (EU), including HER2-positive metastatic breast cancer, HER2-positive early breast cancer and HER2-positive metastatic adenocarcinoma of the stomach or gastroesophageal junction.

“The positive opinion issued by the CHMP for ABP 980 marks an important step for our biosimilar portfolio, as it’s our second oncology biosimilar to reach this important milestone, and further underscores our commitment to providing the oncology community access to high-quality cancer therapies,” said Sean E. Harper, M.D., executive vice president of Research and Development at Amgen. “We look forward to continuing our work with Allergan and European regulatory authorities to bring additional options to patients with cancer.”

The Marketing Authorization Application for ABP 980 was supported by analytical, pharmacokinetic and clinical data, as well as pharmacology and toxicology data. The Phase 3 comparative efficacy, safety and immunogenicity study was conducted in adult female patients with HER2-positive early breast cancer.

“We are committed to providing patients with important medicines to help them fight cancer,” said David Nicholson, chief research and development officer at Allergan. “The CHMP’s positive opinion for the marketing authorization of ABP 980 reinforces its potential to increase physician choice and patient access to an important biologic.”

The CHMP positive opinion will now be reviewed by the European Commission (EC), which has the authority to approve medicines for the EU. If approved, a centralized marketing authorization will be granted that will be valid in the 28 countries that are members of the EU. Norway, Iceland and Liechtenstein, as members of the European Economic Area (EEA), will take corresponding decisions on the basis of the EC’s decision.

Amgen and Allergan are collaborating on the development and commercialization of four oncology biosimilars. Amgen has a total of 10 biosimilars in its portfolio, two of which have been approved by the EC.

About ABP 980

ABP 980 is being developed as a biosimilar to trastuzumab, a recombinant DNA-derived humanized monoclonal immunoglobulin G1 kappa antibody approved in many regions for the treatment of HER2-overexpressing early breast cancer, adjuvant breast cancer, metastatic breast cancer and metastatic gastric cancer. The active ingredient of ABP 980 is a humanized monoclonal antibody that has the same amino acid sequence as trastuzumab. ABP 980 has the same pharmaceutical dosage form and same strength after reconstitution as trastuzumab. Amgen and Allergan also submitted a Biologics License Application to the U.S. Food and Drug Administration (FDA) for ABP 980 in 2017.

About the Amgen and Allergan Collaboration

In December 2011, Amgen and Allergan plc. (then Watson Pharmaceuticals, Inc.) formed a collaboration to develop and commercialize, on a worldwide basis, four oncology antibody biosimilar medicines. This collaboration reflects the shared belief that the development and commercialization of biosimilar products will not follow a pure brand or generic model and will require significant expertise, infrastructure, and investment to ensure safe, reliably supplied therapies for patients. Under the terms of the agreement, Amgen will assume primary responsibility for developing, manufacturing and initially commercializing the oncology antibody products.
