Amgen And Allergan Announce Positive Top-Line Results From Comparative Clinical Study Of ABP 798, Biosimilar Candidate To Rituxan® (Rituximab)
This is the second of two studies intended to support regulatory submissions for ABP 798. The first study was conducted in patients with moderate-to-severe rheumatoid arthritis (RA) and met the primary endpoint of pharmacokinetic similarity. This RA study demonstrated clinical equivalence within the prespecified efficacy margin, and a similar safety and immunogenicity profile.
"Today's results with ABP 798 demonstrate another positive development from
ABP 798 is being developed as a biosimilar candidate to Rituxan, an anti-CD20 monoclonal antibody that is approved in many regions for the treatment of adult patients with non-Hodgkin's lymphoma, chronic lymphocytic leukemia, moderate-to-severe rheumatoid arthritis, pemphigus vulgaris, granulomatosis with polyangiitis and microscopic polyangiitis.
About the JASMINE Study
The JASMINE study was a randomized, double-blind comparative clinical study (study number NCT02747043) that evaluated the efficacy, safety and immunogenicity of ABP 798 compared to rituximab in patients with non-Hodgkin's lymphoma. There were 256 adult patients enrolled and randomized to receive either ABP 798 or rituximab at a dose of 375 mg/m2 administered as an intravenous (IV) infusion once weekly for four weeks followed by dosing at weeks 12 and 20. The primary endpoint of the study was risk difference of overall response rate.
About Non-Hodgkin's Lymphoma
Non-Hodgkin's lymphoma is a type of cancer that originates in the lymph system, part of the body's immune system, and occurs when the body produces too many abnormal lymphocytes, a type of white blood cell.1,2 Non-Hodgkin's lymphoma is one of the most common cancers in the U.S., and about 85 percent of cases originate in B cells.3,4 There are several subtypes, and follicular lymphoma is one of the most common.2
About ABP 798
ABP 798 is being developed as a biosimilar candidate to Rituxan® (rituximab), an anti-CD20- monoclonal antibody that is approved in many regions for the treatment of adult patients with non-Hodgkin's lymphoma, chronic lymphocytic leukemia, moderate-to-severe rheumatoid arthritis, pemphigus vulgaris, granulomatosis with polyangiitis and microscopic polyangiitis. The active ingredient of ABP 798 is a monoclonal antibody that has the same amino acid sequence as Rituxan.
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 assumes primary responsibility for developing, manufacturing and initially commercializing the oncology antibody products.
About Amgen Biosimilars
Amgen is committed to building upon Amgen's experience in the development and manufacturing of innovative human therapeutics to expand Amgen's reach to patients with serious illnesses. Biosimilars will help to maintain Amgen's commitment to connect patients with vital medicines, and Amgen is well positioned to leverage its nearly four decades of experience in biotechnology to create high-quality biosimilars and reliably supply them to patients worldwide.

Amgen Forward-Looking Statements
This news release contains forward-looking statements that are based on the current expectations and beliefs of Amgen. All statements, other than statements of historical fact, are statements that could be deemed forward-looking statements, including estimates of revenues, operating margins, capital expenditures, cash, other financial metrics, expected legal, arbitration, political, regulatory or clinical results or practices, customer and prescriber patterns or practices, reimbursement activities and outcomes and other such estimates and results. Forward-looking statements involve significant risks and uncertainties, including those discussed below and more fully described in the Securities and Exchange Commission reports filed by Amgen, including its most recent annual report on Form 10-K and any subsequent periodic reports on Form 10-Q and current reports on Form 8-K. Unless otherwise noted, Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking statements contained in this document as a result of new information, future events or otherwise.
No forward-looking statement can be guaranteed and actual results may differ materially from those Amgen projects. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for Amgen to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and Amgen expects similar variability in the future. Even when clinical trials are successful, regulatory authorities may question the sufficiency for approval of the trial endpoints Amgen has selected. Amgen develops product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as Amgen may have believed at the time of entering into such relationship. Also, Amgen or others could identify safety, side effects or manufacturing problems with its products, including its devices, after they are on the market.
