Efficacy and irAE Assessment Of Therapeutic Antibodies With Target Specific Knock-In Models

imagePresenter: Dr Hongjuan Zhang, Senior Scientist, Cancer Biology and Immunology

The preclinical development of human-specific immunotherapeutics is currently hampered by a lack of in vivo immunotherapy models for efficacy testing that feature human targets in the presence of a functional immune system. There's also a need to study unique immune-related adverse events (irAEs), caused by I/O agents potentiating tumor-reactive immune responses, leading to on/off target non-specific immune attack.

In this webinar, Dr Hongjuan Zhang explores novel HuGEMM™ and HuCELL™ platforms for assessing human-specific immunotherapies. These models feature humanized drug targets replacing their murine counterpart on host T cells or tumor cells and within a fully functional murine immune system. Hongjuan also presents the latest research applying these platforms to assessing immune related toxicities, to accelerate immuno-oncology drug discovery programs.

Watch this Webinar to Explore:

  • How to use human knock-in models to study clinically-observed immune toxicities related to preclinical I/O drug development
  • The evaluation of urelumab efficacy and liver toxicity using the CD137 HuGEMM model and a chimeric mIgG1 version of the compound
  • The assessment of a human CD40 agonist to study efficacy and both in vitro- and in vivo-mediated immune toxicity using the CD40 HuGEMM model
  • How to use a PD-1/CTLA-4 double knock-in HuGEMM model to mimic clinically observed irAEs, and how to accelerate a new candidate’s safety assessment by de-risking irAEs
  • The effects of CD47 immune checkpoint inhibitors on efficacy and erythrocyte toxicity

Who Should Watch:

  • Oncology researchers studying immune checkpoint inhibitors with related in vivo toxicities
  • Scientists interested in learning how in vivo models are used to evaluate human-specific therapies for both efficacy and toxicity within the same animal model
  • Researchers looking to understand how human knock-in model systems are used to interrogate I/O drug mechanism of action and related toxicity
