The new solutions include an assay for the enumeration and molecular characterization of circulating multiple myeloma cells (CMMC) from peripheral blood samples, the DEPArraysystem upgraded to 9 colors and artificial intelligence software.
The company’s technological developments will be highlighted during a presentation by Mark Connelly, PhD, Chief Research and Development Officer at Menarini Silicon Biosystems Inc, as part of the Molecular Medicine Tri-Conference’s Circulating Tumor Cells & Liquid Biopsy track.
"We are continually working to develop additional tools that will facilitate the exploration of new areas of inquiry," said Connelly. "Providing researchers with more information from a wider variety of cell populations and the ability to examine tumor heterogeneity in real-time could help address some critical questions in pharmaceutical and clinical research."
The CMMC assay based on the capabilities of CELLSEARCH to enrich and enumerate rare cells allow researchers to monitor the number of CMMCs in peripheral blood; furthermore when combined with the DEPArray system, will allow to perform molecular analysis at single cell level**. Research suggests that the ability to obtain CMMCs via liquid biopsy may help clinical researchers to better monitor disease state and treatment response, though, not only the cell enumeration but also the real time cell molecular profiling. Menarini Silicon Biosystems currently offers a CMMC assay (Research Use Only) as a service through its Global Laboratory Services. The company plans to release the assay for Research Use Only in the summer of 2020.
The 9-Color DEPArray will offer more fluorescence channels to examine the heterogeneity of markers expression on various rare cells, enabling researchers to simultaneously identify and characterize multiple cell populations. The artificial intelligence software will reduce operator variability by automating cell identification and selection and will help researchers move beyond enumeration to unravel hidden information in the cell image data.
Connelly’s presentation will also feature new research supporting the potential use of CTCs as a response biomarker for prostate cancer treatment. A 2018 study published in the Journal of Clinical Oncology indicates that using CTC counts obtained from liquid biopsy after 13 weeks of treatment can provide an accurate assessment of response to treatment. PSA (prostate-specific antigen) is one of the only markers currently available for the disease but is not considered to be a sufficient indicator of treatment response.
Menarini Silicon Biosystems is working with the FDA to get this application qualified as a response biomarker. This would enable researchers to incorporate CTCs as a response biomarker into clinical trials to expedite the drug development process.
Jennifer Davids, PhD, Director of Field Scientific Support at Menarini Silicon Biosystems Inc, will also be presenting on how the DEPArray technology can overcome the challenges of sample heterogeneity by enabling rare cell sorting with single cell precision.
