On-Demand Webinar: What the New AAPS White Paper Recommends for Immunogenicity Assays Supporting Biosimilars

Presenter: Todd Lester, Associate Director at BioAgilytix

Co-Hosted with: Bioanalysis Zone

The demonstration of similar immunogenicity is a critical requirement for the demonstration of biosimilarity between a biosimilar candidate and the respective reference product. In their webinar, Mr. Lester discusses what the new AAPS White Paper recommends for immunogenicity assays supporting biosimilars., addressing questions such as:

  • What are the requirements for immunogenicity assessments of biosimilars?
  • Why do the FDA and EMA recommend the use of a single, biosimilar-based assay?
  • How are anti-drug antibody (ADA) assays developed and validated for the support of biosimilar drug development programs?

On-Demand Webinar: Exploratory Biomarker Testing – to Qualify or Validate the Assay?

Presenter: Dr. Afshin Safavi, Founder & Board Member at BioAgilytix

Co-Hosted with: Bioanalysis Zone

With the question ‘should we qualify or validate an exploratory biomarker assay before sample testing?’ in mind, Dr. Safavi will review and discuss the latest scientific and regulatory considerations for the analytical validation of assays for fluid-based biomarkers used in the qualification of drug development tools (DDTs). Topics will cover:

  • Latest industry practices in exploratory biomarker testing
  • Considerations for assay design and technology selection
  • Optimization of pre-analytical factors
  • Core assay performance expectations
  • Setting minimally acceptable assay performance criteria

You can learn more about the topics Dr. Safavi covers in his pre-webinar blog.

Webinar Recording: Clinical relevance of (unwanted drug-induced) immune responses

Presenter: PD Dr. Arno Kromminga, SVP & Chief Scientific Officer at BioAgilytix Europe

Host: Bioanalysis Zone

Ultimately, all biological drugs are immunogenic. Over the last several years, methods for the detection of drug-induced antibodies have become more sensitive, which means that target sensitivities of 100 ng/mL (as recommended in most US FDA immunogenicity guidance) can be easily reached. While it is exciting to have technical tools in hand to detect antibodies at very low concentrations, the question remains to be answered: are antibodies at this low concentration level clinically relevant? In addition, do antibodies against biological drugs, that are detectable prior to the initiation of the treatment, have any clinical implication?

This webinar discusses why careful and thorough data interpretation is needed, which takes into account the clinical manifestation of clinically relevant biomarkers (including PK). Dr. Kromminga also covers how the kinetics and type of antibody responses should be monitored to assess the risk of developing a treatment-emergent immune response, and finally, why post-approval patient monitoring should be mandatory.

Webinar on Demand: Recent Aspects and Challenges in the Assessment of Immunogenicity

The assessment of immunogenicity of biological protein drugs is a key component in drug development. A basic knowledge in immunology is a prerequisite for understanding the principles of adverse, unwanted immune responses. In addition, emerging technologies are making analytical and clinical data interpretation more challenging. Likewise, the comparative immunogenicity analysis of an innovative therapeutic and biosimilar needs to be addressed closely.

Webinar: Assay and Kit Lot Considerations for Single and Multiplex Biomarker Analysis

Abstract: Biomarker analysis has become a common practice by many pharmaceutical companies to help PK/PD modeling.  The reliability of outcomes is heavily influenced by the quality of the reagents.  One of the challenges that bioanalytical labs face when running biomarker studies is the control of lot-to-lot variability of critical reagents and commercial immunoassay kits.  Case studies will be presented to highlight the key bioanalytical considerations involved in running successful biomarker analyses in support of clinical studies.

Afshin Safavi, Ph.D., Founder & Chief Scientific Officer, is a veteran biochemist with extensive experience in establishing and leading bioanalytical teams in support of the development of biological products in preclinical and clinical-trial laboratories.  Prior to founding BioAgilytix, he was the Director of Ligand Binding and Immunoassay, operating under GLP at AAIPharma.  At Talecris BioTherapeutics, he led the Preclinical and Clinical Assay Development team, building on his experience as a senior scientist at Nobex Corporation, GlaxoSmithKline and IGEN International.  Dr. Safavi is considered an expert in the area of immunoassay with a wide working knowledge of various platforms.  He obtained his B.S. in Biochemistry from UCLA, his Ph.D. in Biochemistry from University of Kentucky Medical School, and completed a two-year postdoctoral assignment at the Emory University, Department of Pathology.
