In Vivo Tumor Models
Charles River’s experience with oncology drug discovery spans all phases, from target identification to IND studies. Utilizing the most effective combination of tools available to identify promising compounds, we work with our partners to design studies by selecting from amongst a broad range of well-characterized tumor models.
In Vivo Cancer Models:
- Cell line-derived xenograft models in mice and rats
- Patient-derived xenograft (PDX) models
- Syngeneic models
- Humanized mice tumor models
- Orthotopic models
- Single mouse trials
- Cachexia models
- Graft versus Host models
- Immuno-oncology pharmacodynamic models
Combining these cancer models with appropriate translational tools like ELISpot, flow cytometry, imaging, gene expression analysis, and tumor microdialysis, you can develop the most efficient, relevant study design and screening method to identify promising compounds and optimize lead candidates.
Before entering traditional in vivo efficacy models, using pharmacodynamic models helps to ensure target engagement and immune modulation e.g., adoptive T cell transfer and Graft vs Host (GvHD) models. Cost-effective 2D and 3D assays allow you to screen compounds before entering in vivo tumor models.

Frequently Asked Questions (FAQs) about Cancer Models
What are cancer models?
Cancer models are in vivo mouse models to test and support the development of novel anti-cancer compounds. There are often tumor models using either mouse tumor material (syngeneic models) or human tumor material (Cell line derived xenograft and Patient derived xenograft models), which can be utilized to test the efficacy of cancer treatments.
Which cancer model is the best for my program?
The best choice of cancer models will depend on the specific anti-cancer compound. For example, if you are working with an immunotherapy, then either a syngeneic or humanized model is best, but if your compound has a human target that does not cross react with other species then a humanized mouse tumor model is most advantageous. For a truly translational model, patient-derived xenografts are the gold stanard, as these tumor models preserve the heterogeneity and other characteristics of the patient tumor.
To help decide which model to use for your study contact Charles River.
Which assays should I run before entering in vivo cancer models?
Before entering in vivo mouse models it is essential to learn more about your anti-cancer compound; 2D and 3D tumor models can be used to pre-screen cancer treatments. If the compound is an immunotherapy, we can use a range of immuno-oncology assays to determine the mechanism of action, ensuring you progress the best version of your drug into in vivo cancer models and onto the clinic.
