ANGLE plc’s Microfluidic Liquid Biopsy Technology Featured in Research Presented at American Association of Cancer Researcher's Annual Meeting

Poster presentations at AACR demonstrate isolation of circulating tumor cells in blood using the Parsortix™ system, enabling subsequent molecular characterization

PHILADELPHIA--()--ANGLE plc (AIM:AGL OTCQX:ANPCY), a UK-based medical diagnostics company with pioneering products for cancer diagnostics and fetal health, announces three poster presentations that highlight the advantages of marker-independent capture of circulating tumor cells (CTCs) using the Parsortix cell separation system in blood samples from patients with various types of cancer. The posters will be presented at the American Association of Cancer Researchers Annual Meeting April 1-5.

Researchers Martha Zavridou, Evi Lianidou and colleagues from University of Athens and Attikon University Hospital, (Athens Greece) successfully used the Parsortix system for the first time to isolate CTCs from patients with head and neck squamous cell carcinoma. They were able to extract RNA of excellent quality from the CTCs, which was then used for RT-qPCR gene expression analysis. Preliminary results showing over-expression of key genes -- such as PD-L1 in >26% of samples -- could have significant clinical value in identifying biomarker-positive patients who are likely to respond to individualized immunotherapy.

Yvonne Maertens and a team of researchers from University Hospital Muenster (Germany) compared the ability to isolate and detect circulating renal cancer cells from patient blood samples using the size-based Parsortix system, EpCAM-based CTC enrichment, or methods based on cell density or invasive capacity. The Parsortix system yielded the highest recovery rates of CTCs.

The Parsortix system was used by researchers Jenny Antonello et al. from CRUK Manchester and the Christie NHS Foundation Trust Manchester (U.K.), together with an epitope-dependent EpCAM-based enrichment method to capture CTCs over time from blood samples of patients with prostate cancer as part of a study to identify and monitor biomarkers that may be linked, either alone or in combination, to clinical status or outcomes.

“We are very pleased with the increased adoption and utilization of Parsortix™ cell separation in such diversified research. We continue to see greater utilization of our flagship technology in key liquid biopsy research,” said ANGLE Founder and Chief Executive, Andrew Newland.

About ANGLE plc

ANGLE is a UK-based specialist medtech company commercializing the Parsortix system, a cell separation technology that enables a simple blood test to harvest targeted cells for investigation, such as circulating tumor cells (CTCs) for molecular profiling and analysis. Parsortix can help deliver targeted cancer diagnostics that has the potential to inform personalized treatment of cancer. It is also designed to be compatible with existing major medtech analytical platforms and to act as a companion diagnostic for major pharma in helping to identify patients that will benefit from a particular drug and then monitoring the drug’s effectiveness. ANGLE has established formal collaborations with world-class cancer centers and is working with these cancer centers to demonstrate key applications for its Parsortix non-invasive cancer diagnostic system as a liquid biopsy. In addition to cancer cells, the Parsortix technology has the potential for deployment for other clinically significant cell types in the future.

ANGLE is a public company trading on the AIM market of the London Stock Exchange under the ticker symbol AGL and on the OTCQX market in the US under the ticker symbol ANPCY. For more information, www.angleplc.com.
