This screen provides a cost effective and time efficient way to fast-track in vivo preclinical immunotherapy development.

Choose MuScreen to:

  • Quickly identify responder models or markers saving time and improving efficiency
  • Evaluate the efficacy of your compound across well-characterized syngeneic and tumor homograft models
  • Investigate pharmacodynamic (PD) effects using our syngeneic model panels
  • Benefit from Crown Bioscience covering the cost of the vehicle group for all models
  • Benefit from a discount on shared control groups

Tumor homografts are transplants of spontaneous or carcinogen-induced GEMM tumors in immunocompetent syngeneic hosts. They preserve the original GEMM tumor molecular and histopathology as well as clinically relevant oncogenic driver mutations.

Our MuPrime tumor homografts have been developed to broaden the number and molecular pathology of preclinical syngeneic models for in vivo pharmacology studies.

Key advantages of MuPrime tumor homografts include:

  • Fully immune competent
  • Relevant tumor stroma
  • Mimic original GEMM tumor molecular and histopathology
  • Encompass disease-specific mutations of human cancers
  • Similar disease progression as original GEMM tumors

Our tumor homograft models are well characterized with available characterization data including:

  • Immune checkpoint inhibitor benchmarking
  • Baseline tumor immune profile
  • Tumor RNAseq

Efficacy and PD Mode

 

MuScreen Efficacy and PD Mode are run following a preset schedule along with a shared vehicle group.

The main study endpoint for the efficacy mode is Tumor Growth Inhibition (TGI) with optional terminal Mouse I/O RNA-Seq Panel readout, FACS and IHC.

In the PD mode, choose between FACS analysis of tumor infiltrating lymphocytes and tumor associated macrophages at selected time points, and Mouse I/O RNA-Seq Panel which comprehensively profiles 1080 genes associated with tumor immunity, as your main endpoint. Additional endpoints include cytokine panel profiling in blood and tumor, IHC for biomarker analysis on tumor tissues, blood cells, lymph nodes, and spleen cells.

Frozen or fixed tumors are available on request for both modes.
