New Data Published in Gastroenterology Demonstrate the Power of Fluidigm’s Imaging Mass Cytometry on the Hyperion Imaging System to Identify Novel Targets for Pancreatic Cancer Therapy

Study Highlighting IMC Application in Both Protein and RNA Detection Conducted by Researchers at Fluidigm Center of Excellence for Imaging Mass Cytometry at Georgetown Lombardi Comprehensive Cancer Center

SOUTH SAN FRANCISCO, Calif., Jan. 05, 2021 (GLOBE NEWSWIRE) -- Fluidigm Corporation (NASDAQ:FLDM), an innovative biotechnology tools provider with a vision to improve life through comprehensive health insight, today announced the publication of a new study led by Georgetown Lombardi Comprehensive Cancer Center that further validates the potential for Imaging Mass Cytometry™ (IMC™) on the Hyperion™ Imaging System to provide new insights into the interactions between pancreatic tumor cells and the immune system and to identify novel targets for therapeutic intervention.

The study also highlights the application of IMC in both protein and RNA detection, a capability that is extremely valuable for investigators studying the biological processes in single cells and precious tissue samples. The study data have been published in the journal Gastroenterology.

A Fluidigm® Center of Excellence for Imaging Mass Cytometry (CoE) was established at Georgetown Lombardi in early 2020. The Fluidigm CoE program accelerates adoption of mass cytometry through the development of new highly multiplexed panels for the study of cancer, immuno-oncology and immune-mediated diseases.  

Pancreatic cancer is the third-leading cause of cancer-related death in the United States. The team led by Georgetown Lombardi partnered with Fluidigm Therapeutic Insights Services (TIS) to conduct the study, which combined IMC with RNAscope Technology.

Researchers at Georgetown Lombardi, Georgetown University, Lawrence Livermore National Laboratory, University of California, Merced, University of California, Davis, STCube Pharmaceuticals and Fluidigm used 12 distinct IMC probes to conduct RNAscope analysis on normal and diseased pancreatic cells and to evaluate interactions between these cells and cells of the immune system. RNAscope is a novel in situ hybridization assay for detection of target RNA within intact cells, and this publication is the first to report its use in a multiplexed fashion with 12 different probes, enabling simultaneous evaluation of multiple targets of interest and generating richer datasets.  

“Pancreatic tumor cells have a fibrotic, immunosuppressive microenvironment, and this study was designed to evaluate if strategies that alter this microenvironment might help activate an antitumor immune response,” said Stephen Byers, PhD, Associate Director and Professor of Oncology at Georgetown Lombardi and senior author of the publication. “Results demonstrate that CDH11, which is overexpressed on cancer-associated fibroblasts, allows cancer cells to escape detection by the immune system. Inhibiting CDH11 expression in mice significantly extended survival and restored sensitivity to gemcitabine, a chemotherapy agent used in the treatment of pancreatic cancer.

“These findings suggest that CDH11 could have significant potential as a novel target for pancreatic cancer therapy.”

Key findings of the study include:

  • Levels of CDH11 mRNA and protein were significantly higher in cancer-associated fibroblasts than in pancreatic cancer epithelial cells, human or mouse pancreatic cancer cell lines or immune cells.
  • Mice in which one or both copies of the CDH11 gene had been knocked out survived significantly longer than mice with both copies of the gene.
  • Compared with pancreatic tumors in mice with two copies of CDH11, tumors in mice with only one copy had increased markers of immune system activity, decreased extracellular matrix component and reductions in markers and cytokines associated with immunosuppression.
  • Gemcitabine extended survival only in mice that lacked one or both copies of CDH11 or when administered in combination with an anti-CDH11 antibody.
  • A small molecule inhibitor of CDH11 reduced the growth of pre-established pancreatic tumors only if T and B cells were present in mice.

Fluidigm Research and Development and the company’s TIS program provided support in conducting the IMC analysis for the study. TIS, created to test and develop new solutions based on IMC, provided access to IMC technology, services and data analysis, while R&D scientists developed the method of conjugating metals to RNAscope reagents.

“Fluidigm is committed to harnessing the power of our technologies to inform new approaches to therapies, and this published study demonstrates our ability to generate insights that have the potential to advance cancer care and outcomes,” said Andrew Quong, Chief Science Officer of Fluidigm and an author of the publication. “Significantly, the study also highlights the potential for IMC in both protein and RNA detection. This capability is extremely valuable for investigators studying the biological processes in single cells and with precious tissue samples.

“We established our Therapeutic Insights Services to expand access to our IMC and mass cytometry technologies. Going forward, we intend to leverage TIS to power additional groundbreaking research in our growing and evolving Center of Excellence program. The scientific and technological advances made in partnership with the CoE researchers will be made available to other scientists through TIS and the launch of new products. Access to these advances will accelerate the impact of mass cytometry in understanding critical biologic processes and the translation of those insights into novel therapies and clinical practice.”

About Imaging Mass Cytometry
Imaging Mass Cytometry is setting a new standard in tissue imaging, significantly simplifying high-multiplex panel design and eliminating the impact of tissue autofluorescence by using highly pure metal tags for which signals are separated by mass instead of by wavelength. Incorporating an easy-to-use immunohistochemistry workflow that simultaneously detects many proteins in a single scan, IMC is ideal for uncovering new insights in health and disease and empowering the development of better diagnostics and more effective therapies.
