ANGLE plc ("the Company")

 

PARSORTIX SYSTEM RESULTS PUBLISHED AS A POSTER AT LEADING CANCER CONFERENCE
AACR 2022

 

Poster demonstrated use of Parsortix workflow for triple negative breast
cancer

 

ANGLE plc (AIM:AGL OTCQX:ANPCY), a world-leading liquid biopsy company, is
pleased to announce that the Company has presented a poster showcasing the
Parsortix(®) system at the American Association for Cancer Research
Conference (AACR) 2022, held in New Orleans, United States on 8-13 April 2022.

 

The research presented related to the use of the Parsortix system with triple
negative breast cancer (TNBC) patients. TNBC is a form of invasive breast
cancer, which has limited treatment choices and a poor prognosis.

 

The poster attracted industry interest as it demonstrated the ability to
analyse cancer cells harvested from patient blood samples, known as
circulating tumour cells (CTCs), for key markers of interest and, as a result
of its capability to investigate both mesenchymal and epithelial CTCs, a
significantly higher positivity rate than alternative approaches. Key features
included the high proportion of CTCs of mesenchymal phenotype and the high
proportion of patient samples with CTC clusters, both of which are key
differentiating factors of the Parsortix system.

 

ANGLE is offering this workflow as part of its pharma services business for
longitudinal monitoring of patients in cancer drug trials.

Notes for editors

 

About ANGLE plc www.angleplc.com (http://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 59
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.
