Efficacy Studies Accelerating Drug Discovery
We offer customizable study designs, to test the effectiveness of novel or existing therapeutic compounds to advance cancer research and enable the selection of immuno-therapeutics and personalized cancer treatments. We have established and banked over 350 early passage Patient-Derived Xenograft (PDX) models that more accurately recapitulate primary human tumor biology.
Trial Simulation
Typically, cohorts of PDX-bearing NSG™ mice are randomized onto a study when tumors reach ~250 mm3. A sample standard study design, as follows, is customizable to your specifications in collaboration with your dedicated In Vivo Pharmacology Study Director and their team.
Dosing
- Vehicle and drug formulated under your defined conditions
- Standard delivery methods available (IP, IV, SC, PO, ID and others possible)
- 1-5 weeks dosing period up to 21 doses per mouse
Biweekly Measurements
- Tumor caliper dimensions
- Body weight monitoring
- Clinical observations
Study Termination
- Tumor volume of 1500 mm3 or 60 days post treatment initiation
- Tumors can be collected for biomarker analysis, flow cytometry, gene expression and histology
Efficacy Testing of Cancer Immunotherapeutics in hu-NSG™
This innovative service offers a valuable preclinical testing platform for immuno-oncology, to simulate trials, evaluate multiple drugs alone or in combination, to produce predictive data. JAX In Vivo Pharmacology Services has experience engrafting primary human tumor (PDX) and cell-line tissues in humanized NSG™ mice and has the capability to evaluate immune checkpoint drugs alone or in combination.
