Angle PLC Announces Update on Lab Accreditation and Ovarian Study

First submissions made in relation to accreditation of ANGLE clinical laboratories

Ovarian cancer study sample analysis slower than planned

GUILDFORD, SURREY / ACCESSWIRE / January 13, 2022 / ANGLE plc (AIM:AGL)(OTCQX:ANPCY), a world-leading liquid biopsy company, provides an update on its plans for accreditation of its clinical laboratories and on its ovarian cancer study.

First submissions have been made in relation to CLIA and UKAS accreditation of the Company’s United States and UK clinical laboratories respectively. In the United States, these processes are in hand pending results of the ovarian cancer study evaluating the combined use of ANGLE’s Parsortix^® and HyCEAD™ platforms as a simple blood test to detect the presence of ovarian cancer in women with an abnormal pelvic mass, which is nearing completion.

While good progress has been made in many areas of the ovarian cancer study, there have been some third-party supply chain difficulties attributed to COVID-19. A key supplier has been unable to deliver certain reagents as scheduled. Completion of the study sample analysis depends on these reagents and the situation is being closely managed. Consequently, headline results for the study are now expected in H1 2022.

ANGLE Founder and Chief Executive, Andrew Newland, commented:

“The third-party supply chain issues were unexpected but are being closely managed and we look forward to reporting headline results from our ovarian cancer study once the sample analysis has been completed.

Separately, we remain on track to achieve the first ever FDA product clearance, the gold standard for medical devices globally, for a system to harvest cancer cells from patient blood for subsequent analysis, initially in metastatic breast cancer. Ongoing and constructive dialogue with FDA continues and a regulatory decision from FDA is awaited.”

About ANGLE plc www.angleplc.com

ANGLE is a world leading liquid biopsy company with sample-to-answer solutions. ANGLE’s proven patent protected platforms include a circulating tumor cell (CTC) harvesting technology and a downstream analysis system for cost effective, highly multiplexed analysis of nucleic acids and proteins.

ANGLE’s cell separation technology is called the Parsortix^® system, and it enables a liquid biopsy (a simple blood test) to be used to provide the cells of interest to the user in a format suitable for multiple types of downstream analyses. The system is based on a microfluidic device that captures cells based on a combination of their size and compressibility. The system is epitope independent and can capture all types of CTCs as well as CTC clusters in a viable form (alive). CTCs enable the complete picture of a cancer to be seen; as being an intact cell they allow DNA, RNA and protein analysis and may provide comparable analysis to a tissue biopsy. Because CTC analysis is a non-invasive process, unlike tissue biopsy, it can be repeated as often as needed. This is important because cancer develops and changes over time and there is a clear medical need for up-to-date information on the status of a patient’s tumor. In addition, the live CTCs harvested by the Parsortix system can be cultured, which offers the potential for testing tumor response to drugs outside the patient.

The Parsortix technology is the subject of 26 granted patents in Europe, the United States, China, Australia, Canada, India, Japan and Mexico with three extensive families of patents are being progressed worldwide.

The Parsortix system has a CE Mark in Europe for the indicated use and, in the United States, a De Novo Submission has been made to FDA for the Parsortix^® PC1 system seeking FDA clearance with Class II Classification for use with metastatic breast cancer patients. FDA clearance is seen as the global standard. ANGLE is seeking to be the first ever FDA cleared system for harvesting CTCs for subsequent analysis.

ANGLE has also completed two separate 200 subject clinical studies under a program designed to develop an ovarian cancer pelvic mass triage test, with the results showing best in class accuracy (AUC-ROC) of 95.1%. The pelvic mass triage assay has undergone further refinement and optimisation and a 200 patient clinical verification study has now completed enrolment.

ANGLE’s technology for the multiplex evaluation of proteins and nucleic acids of all types is called the HyCEAD^TM platform and is based on a patented flow through array technology. It provides for low cost, highly multiplexed, rapid and sensitive capture of targets from a wide variety of sample types. A proprietary chemistry approach (the HyCEAD method) allows for the capture and amplification of over 100 biomarkers simultaneously in a single reaction. The HyCEAD system is extremely sensitive and is ideal for measuring gene expression and other markers directly from Parsortix harvests and was used in the ovarian cancer pelvic mass triage test to achieve best in class accuracy (AUC-ROC) of 95.1%.

ANGLE’s proprietary technologies can be combined to provide automated, sample-to-answer results in both centralised laboratory and point-of-use cartridge formats.

ANGLE has established formal collaborations with world-class cancer centres and major corporates such as Abbott, Philips and QIAGEN, and works closely with leading CTC translational research customers. These Key Opinion Leaders (KOLs) are working to identify applications with medical utility (clear benefit to patients), and to secure clinical data that demonstrates that utility in patient studies. The body of evidence as to the benefits of the Parsortix system is growing rapidly from our own clinical studies in metastatic breast cancer and ovarian cancer and also from KOLs with 53 peer-reviewed publications and numerous publicly available posters, available on our website.

ANGLE has established clinical services laboratories in the UK and USA to accelerate commercialisation of the Parsortix system and act as demonstrators to support product development. The laboratories offer services to pharmaceutical and biotech customers for use of Parsortix in cancer drug trials and, once the laboratories are accredited and tests validated, will provide Laboratory Developed Tests (LDTs) for patient management.
