ASCO 2019

During this week’s 2019 American Society of Clinical Oncology Annual Meeting, researchers reported on the cardiac safety of Amgen’s biosimilar trastuzumab, ABP 980 (approved in the European Union under the name Kanjinti), versus the reference trastuzumab, Herceptin.
Multiple biosimilars of pegfilgrastim are available in both the United States and Europe, and the field of competitors to Amgen’s brand-name Neulasta continues to expand. During the 2019 American Society of Clinical Oncology Annual Meeting, 3 research teams shared their findings on biosimilar pegfilgrastim development programs from sponsors Sandoz, Fresenius Kabi, and Gema Biotech.
While no biosimilar rituximab products have yet become available in the United States, biosimilar rituximab products are available in the European Union, and data on their use, published concurrently with the 2019 American Society of Clinical Oncology Annual Meeting, highlight not only their safety but also their growing acceptance among prescribers in Europe.
During this week’s 2019 American Society of Clinical Oncology Annual Meeting, researchers presented the final overall survival results from the phase 3 HERITAGE study of biosimilar trastuzumab, Ogivri. In addition, another research group shared its findings on postmarketing surveillance of Ogivri in Brazil.
During the 2019 American Society of Clinical Oncology Annual Meeting, researchers said that, for payers with large populations, the discounted biosimilar pegfilgrastim can produce substantial cost savings that can be applied to offer increased access to supportive care.
Between patients treated with the biosimilar and those treated with the reference product who were not exposed to lots of Herceptin with lower antibody-dependent cell-mediated cytotoxicity, no difference was observed in event-free survival (EFS) or overall survival (OS).
Alongside this week’s 2019 annual meeting of the American Society of Clinical Oncology, 3 developers reported on their progress with developing biosimilars of bevacizumab.
