Article on hyperpolarised xenon
Polarean Imaging plc (AIM: POLX), the medical - imaging
technology company, with an investigational drug - device
combination product for magnetic resonance imaging (MRI), notes the
news release on 25 May by the Oxford Biomedical Research Centre
concerning a study carried out in longer-term lung damage after
COVID-19.
The study was published online in the Journal Radiology (
https://pubs.rsna.org/doi/10.1148/radiol.2021210033 ). This
preliminary research determined that hyperpolarised xenon MRI scans
had found abnormalities in the lungs of some COVID-19 patients more
than three months - and in some cases, nine months - after leaving
hospital, when other clinical measurements were normal. Polarean
had supplied Oxford University Hospitals Trust with an earlier
research model that was used for the study and are working towards
providing a new state-of-the-art polariser for further
research.
Principal Investigator Prof Fergus Gleeson, Professor of
Radiology at the University of Oxford and Consultant Radiologist at
Oxford University Hospitals NHS Foundation Trust, said: "Many
COVID-19 patients are still experiencing breathlessness several
months after being discharged from hospital, despite their CT scans
indicating that their lungs are functioning normally. Our follow-up
scans using hyperpolarised xenon MRI have found that abnormalities
not normally visible on regular scans are indeed present, and these
abnormalities are preventing oxygen getting into the bloodstream as
it should in all parts of the lungs."

About Polarean ( www.polarean.com )
The Company and its wholly owned subsidiary, Polarean, Inc.
(together the "Group") are revenue-generating, investigational
drug-device combination companies operating in the high-resolution
medical imaging research space.
The Group develops equipment that enables existing MRI systems
to achieve an improved level of pulmonary function imaging and
specialises in the use of hyperpolarised Xenon gas ((129) Xe) as an
imaging agent to visualise ventilation. (129) Xe gas is currently
being studied for visualisation of gas exchange regionally in the
smallest airways of the lungs, across the alveolar tissue barrier,
and into the pulmonary bloodstream.
In October 2020, the Group submitted a New Drug Application
("NDA") to the FDA for hyperpolarised (129) Xe used to evaluate
pulmonary function and to visualise the lung using MRI. In December
2020, the Group received confirmation of acceptance of its NDA by
the FDA, with a target PDUFA action date of 5 October 2021.
The Group operates in an area of significant unmet medical need
and the Group's technology provides a novel investigational
diagnostic approach, offering a non-invasive and radiation-free
functional imaging platform. The annual burden of pulmonary disease
in the US is estimated to be over US$150 billion.
