IONpath and Bristol Myers Squibb Jointly Author New Laboratory Investigation Article Exploring the Complexities of the Tumor Microenvironment

MENLO PARK, California, March 31, 2020 /PRNewswire/ — IONpath, Inc. today announces that they have jointly authored with Bristol Myers Squibb an article entitled Multiplexed Ion Beam Imaging (MIBI) for Characterization of the Tumor Microenvironment Across Tumor Types [] for the Nature journal Laboratory Investigation. []

The ability to understand all the cells present within a tumor by differentiating several cell types at once in a single tissue section has been limited by the technology available. Here the authors showed how Multiplexed Ion Beam Imaging (MIBI(TM)) is able to detail the features of a wide variety of tumor types by providing cell phenotype identification coupled with analysis of their spatial relationships. For this collaboration, Bristol Myers Squibb provided samples from 50 tumor biopsies to IONpath where they were simultaneously stained with a panel of 15 antibodies, each labeled with a specific metal isotope. Highly detailed mapping of the tumor microenvironment provided an immune profile((fig 1) ) and spatial organization ((fig 2)) through a multi-step process that segmented the sample down to the individual cell.

This information was gathered as an exercise to observe the characteristics of the samples in question. However, the implications of this new level of tumor mapping at a cellular level could be far reaching. Scientists and drug developers are now able to measure the proximity of immune cells to cancer cells and, within the same sample, measure the protein expression levels of potential drug targets and other variables associated with response to certain therapies such as those targeting immune checkpoints.

“It is IONpath’s mission to empower medical discovery, specifically in the area of immuno-oncology, through the characterization of the tumor microenvironment down to the cellular level,” said Dr. Jessica Finn, Director of Pathology and one of the authors of the article. Dr. Finn adds, “Examining these detailed and interrelated structures is difficult but important work in the fight to cure certain types of cancer.”

As an example of how this mission for IONpath may impact real world decisions, this study demonstrated the possibilities for calculating distances between different cell subsets including tumor and immune cells in addition to PD-1 and PD-L1 expressing immune cell subsets. Further studies in this area may be designed to support better outcomes in the field of immuno-oncology.
