Benefits of Services at JAX

  • Project support from Ph.D.-level study directors from initial study design to reporting
  • Extensive experience conducting large-scale GvHD studies for commercial clients
  • Outcomes compared to a clinically-approved immunosuppressive drug (e.g., etanercept)
  • Industry leading PBMC-humanized-NSG™ mice

Industry-Leading Hu-PBMC-NSG™

Humanized-PBMC-NSG™ mice are widely used as models of human-to-mouse xenogeneic GvHD, as well as studying immune function in vivo. Peripheral blood mononuclear cells (PBMCs) engraft with high efficiency into NSG™ mice due to the lack of mature murine lymphocytes and natural killer cells. The high degree of immunodeficiency allows engraftment of larger cohorts from a single donor, creating a robust and reproducible study platform.

GvHD Study Design

Standard study includes: 

  • Midpoint and terminal blood samples
  • Survival curves
  • Study report

Optional Add-Ons:

  • FACS analysis of blood
  • Tissue collection 
  • Additional treatment arms
  • Alternative benchmarking agent available
 

Example Study

Shown in the figure below are sample control and vehicle arms of a standard five arm study.  Survival (A) and body weight (B) data demonstrate efficacy of the immunosuppressive drug Enbrel® (etanercept) in this platform. Standard studies run for thirty-five days and include dosing up to three times weekly for five weeks. Assessments are performed three times per week. A quality control group is engrafted in parallel with study arms to confirm PBMC engraftment.

 GvHD

Sample data from preclinical GvHD study. A. Survival curve of saline-treated control (group 1) vs treatment with Enbrel® (etanercept, group 2). B. Mean body weight of untreated control group declines significantly more rapidly than treatment group (n = 20 or 12 per group).

Note: Disease Activity Index scoring is used to closely monitor animal health according to strict guidelines and approval by the Animal Care and Use Committee.
