SC3: Validation of ADA Assays and Cut Point Calculations


Viswanath Devanarayan, Ph.D., Executive Director, Global Statistics, Charles River Labs

Jim McNally, Ph.D., Principal, McNally Bioanalytical Consulting LLC

This short course will focus on the validation of ADA Assays and Cut Point evaluations. We will provide an in-depth overview of the basic considerations around ADA assay validation, with significant focus on the process of evaluating different types of cut-points, and the translation of the cut-point established during validation to the real world implementation during a pre-clinical or clinical study.

  • Tiered Testing Strategy - Basic issues regarding screening, confirmatory and titer assays
  • ADA Assay Validation Strategies – Experimental Design to execute a validation
  • Stepwise process for calculating different types of cutpoints
  • Practical challenges for the in study implementation of cutpoints
  • Case Studies related to the implementation of validation and study specific cutpoints
