Charles River Laboratories updates oncology business

Wednesday, May 17, 2017

Charles River Laboratories International recently announced updates to its expanding oncology discovery business, including significant additions to its online Tumor Model Compendium. The Compendium provides oncology researchers with a resource to identify and locate targeted suitable patient-derived xenografts (PDXs) based on specific histology and molecular properties, and now includes additional molecular characteristics for syngeneic models.

“The use of a human tumor graft in a humanized model represents the future of immuno-oncology research,” said Birgit Girshick, corporate senior vice president, Global Discovery, at Charles River. “A model that more closely mirrors human immune systems allows researchers to conduct groundbreaking studies more efficiently and effectively, with the goal of developing more translational therapies. Utilizing the Tumor Model Compendium, oncology researchers can identify the exact tumor model and target for their research, getting them that much closer to that goal.”

Charles River has more than 450 fully characterized proprietary PDXs in its portfolio, which represents all major tumor histotypes, and provides extensive background and characterization for oncology research. The most recent Compendium update expands the existing tumor model collection to include:

  • Whole-exome mutations determined by Next-Generation Sequencing
  • Gene copy number variations determined by using Affymetrix Genome-Wide Human SNP Array 6.0
  • Gene expression determined by using Affymetrix Human Genome U133 Plus 2.0 Array

Recognizing the importance of selecting the appropriate tumor model for in vivo and in vitro oncology, Charles River partnered with OcellO to further expand their capabilities with PDX models. Through their agreement, OcellO utilizes human tumor material from Charles River PDX models and applies it in their 3D cell culture drug screening platform. This high-throughput platform enables the growth of micro-tumors in a natural extracellular matrix environment and uses automated 3D imaging to analyze the effects of small molecules and antibodies on tumor development.

“The extended range of tumor subtypes and high level of annotation of Charles River’s PDX Compendium enables the selection of the optimum tumor models with the most appropriate mutational profile for in vivo studies,” said Leo Price, CEO and founder of OcellO. “The use of the same PDX tumor cells in OcellO’s in vitro 3D culture platform enables pre-screening of tumor models with test compounds in a highly translational high-throughput platform.”
