CrownBio 2017. Poster: Humanized CD137 Models for Preclinical Drug Development
PD-1/PD-L1 checkpoint inhibitors have achieved huge clinical success (and drug approval) across a range of cancer types. However, overall response rates to these agents remains low.

Efforts are now focused on combination strategies which could improve T cell tumor killing activities. For example, agonist CD137 antibodies could be used in combination with anti-PD-1/PD-L1 agents to both prime and activate T cells.

Research into these antibodies is being hindered by a lack of preclinical animal models for the in vivo assessment of human-specific therapeutics. CrownBio has developed a range of humanized drug target immunocompetent models, including a CD137 model, to enable novel immunotherapy and combination evaluation.

Read this Poster to Discover:

  • The development of a CD137 humanized model (with human CD137 within fully competent murine immunity) for evaluating CD137 mAb therapeutic efficacy

  • Response to anti-CD137 antibody treatment, and combination therapy with CD137 + PD-1/PD-L1 antibodies, by MC38 tumors engrafted within this model

  • Our range of available preclinical target humanized models, including PD-1, PD-L1, CTLA-4, and OX40, used to assess immunotherapeutic efficacy
