Monoclonal antibodies and checkpoint inhibitors have achieved remarkable clinical success in cancer immunotherapy. Two bispecific antibodies, catumaxomab and blinatumomab, have also been approved to treat cancer patients, and many more are currently in preclinical or clinical development.
This has led to an increased need for fast, reliable, and cost effective mouse tumor models with functional immune systems for immuno-oncology drug discovery, including for targeted cancer immunotherapy assessment.
CrownBio has developed a panel of PBMC-humanized mouse tumor models, which have a broad spectrum of applications in immuno-oncology including the in vivo evaluation of targeted immunotherapeutics such as bispecific T cell engagers. This poster details the development, characterization, and optimization for a range of models from this platform, which overexpress a variety of tumor antigens (e.g. EGFR, CD47, Braf, PD-L1, etc).
