Clinical and Bioanalytical Aspects of Immune Monitoring via ELISpot

Life Sciences, Clinical Trials, Drug Discovery & Development, Biomarkers, Laboratory Technology,
  • Thursday, December 16, 2021

The enzyme-linked immunosorbent spot (ELISpot) assay is widely recognized as a powerful tool to monitor the immune system in response to therapeutic agents. Specifically, B-cell ELISpot provides information on antigen-specific antibody-secreting cells, including memory B cells. In addition, antigen-specific T-cell responses, most commonly measured by interferon-gamma (IFN-γ), yield valuable insight during clinical studies.

Join this webinar to learn how immune monitoring assays, such as ELISpot and intracellular cytokine staining (ICS), provide unique challenges in a regulated environment as no reference material or gold standard is utilized. The FDA Bioanalytical Method Validation (BMV) guidance is not always applicable and may need to be adapted to the unique properties of ELISpot to achieve a fit-for-purpose validation.

The frequent use of ELISpot in clinical trials highlights its importance to a wide variety of fields, such as HIV and other infectious diseases, oncology, autoimmunity, gene therapy and vaccines. With recent advances in mRNA vaccines, understanding the durability of the cellular immune response compared to other modalities will expand the understanding of mechanisms for new vaccine technologies. Over 400 clinical trials used ELISpot as a primary or secondary endpoint. Consequently, the quality of the data stemming from point of collection to statistical analysis is paramount.

Global harmonization efforts for ELISpot application include the creation of optimized assay protocols, counting guidelines, targets for precision and linearity and finally response definitions. Sample collection and processing methods for peripheral blood mononuclear cells (PBMCs), including mechanisms of suppression of T-cell functionality, are thoroughly explored within the literature. Although key to preserving the responsiveness of the PBMCs, sample collection and handling is still an area often neglected at the validation stage.

Register for this webinar in which expert speakers will address the challenges of measuring a complex immune biomarker in the bioanalytical environment by utilizing a comprehensive validation and bioanalytical study plan, including clear guidance for sample collection.
