On-target development - Specificity screening of biotherapeutics to avoid off-target liabilities
July 16, 2020
11 am to 12 pm EDT



Webinar Description:

Ensuring that a novel biotherapeutic is specific to its intended target is undoubtedly advantageous when selecting promising lead candidates, however, it becomes vital when assessing potential safety implications prior to clinical studies. The unique Cell Microarray technology identifies primary receptors and any potential secondary targets with a high degree of specificity and sensitivity, providing valuable data that can inform lead selection, assist with safety assessment and support regulatory submissions. Cell Microarray data confirming target specificity have been included in IND submissions to various regulatory agencies, such as the FDA (US), EMA (Europe), NMPA (China) and PMDA (Japan), either in complement with, or as a replacement for, tissue cross reactivity data.

This webinar provides an overview of the Cell Microarray technology, with a particular focus on specificity/off-target screening. Industry case examples will highlight data generated for a variety of biotherapeutic modalities and show the utility of the platform from early lead candidate selection through to pre-IND safety, and clinical trial stages.

Learning Objectives:

  • Understand how the data generated with Cell Microarray screening is used in lead selection and safety assessment
  • Learn how specificity data supports IND submissions as either an adjunct to, or replacement for, tissue cross reactivity studies
  • Learn more about identifying and mitigating the risk of clinical toxicity caused by off-target effects of monoclonal antibodies
