Misinformation about interchangeable biosimilars undermines US health policy, physician confidence, and patient health

Author byline as per print journal: Michael S Reilly, Esq; Ralph D McKibbin, MD, FACP, FACG, AGAF Abstract: The US biosimilar programme has been highly successful with 53 biosimilars approved by the US Food and Drug Administration (FDA) for 17 reference products. As in most advanced nations of Europe, all FDA-approved biosimilars may be substituted […]


Biosimilar antibody drug conjugates: considerations of higher order structure and aggregation

Abstract: Undoubtedly the complexity of antibody drug conjugate (ADC) molecules where three components (monoclonal antibody, cytotoxic drug and appropriate linker) are involved poses a challenge for biosimilar development. As with all biomolecule development, both novel and biosimilar, it is important to choose orthogonal analytical techniques to interrogate Quality Attributes, particularly for higher order structure (HOS) […]


Demonstrating interchangeability and biosimilarity for US biosimilars

Abstract: The US Food and Drug Administration (FDA) outlines its approach to biosimilarity and interchangeability at the 2016 Generic Pharmaceutical Association Biosimilars Council Conference. Topics covered include the FDA definition of biosimilarity, its step-wise approach to the approval process and factors/issues that should be considered when providing scientific justification for extrapolation. Submitted: 22 September 2016; […]


New monoclonal antibody biosimilars approved in 2015 in Latin America: position statement of the Latin American Forum on Biosimilars on biosimilarity, interchangeability and extrapolation of indications

Author byline as per print journal: Valderílio Feijó Azevedo1,2, Alejandra Babini3,4, Fabio Vieira Teixeira5,6, Igor Age Kos1,2, Pablo Matar7 Introduction: The Latin American Forum on Biosimilars (FLAB) is an annual meeting that brings together various stakeholders, including key opinion leaders, the pharmaceutical industry, academics, patients, lawyers and other healthcare professionals, to present and discuss recent […]


Supporting biosimilarity and extrapolation

Abstract: With many biosimilars being approved around the world, there is an urgent need for clear guidelines on establishing biosimilarity and on approving subsequent extrapolation. The balance between clinical studies and analytics in establishing and confirming biosimilarity are discussed in this paper. Submitted: 28 July 2015; Revised: 15 August 2015; Accepted: 16 August 2015; Published […]


Recommendations for the regulation of biosimilars and their implementation in Latin America

Author byline as per print journal: Valderilio Feijó Azevedo, MD, PhD; Eduardo Mysler, MD; Alexis Aceituno Álvarez, PharmD, PhD; Juana Hughes, MSc; Francisco Javier Flores-Murrieta, PhD, FCP; Eva Maria Ruiz de Castilla, MS, MAA, PhD Abstract: With the emergence of biosimilars as a new class of biotherapeutic agents, the use of these products in Latin America has become a focus […]


Establishment of reference standards in biosimilar studies

Author byline as per print journal: Aijing Zhang, PhD, Associate Professor Jung-Ying Tzeng, Professor Shein-Chung Chow, PhD Abstract: When an innovative biological product goes off-patent, biopharmaceutical or biotechnological companies may file an application for regulatory approval of biosimilar products. In practice, however, important information on the innovative (reference) product may not be available for assessment. Thus, […]


Biosimilarity in Latin America

Abstract: The introduction of new legislation in Latin America for the approval of biosimilar products follows implementation of EU legislation in 2005 for biosimilars approval. The establishment of regulatory processes for these complex drugs will ensure that evidence of safety and efficacy is obtained before approval. Biosimilars are high on the health-policy agenda because they […]


Assessing biosimilarity and interchangeability of biosimilar products under the Biologics Price Competition and Innovation Act

Author byline as per print journal: Professor Shein-Chung Chow, PhD, Christine Ju, MSc Abstract: Biological (large molecule) drug products are made via living systems and are complex and variable in nature. As a result, generic forms of biological products, also termed biosimilars in the EU or follow-on biologics by the US Food and Drug Administration, can […]
