Scientific presentations on hyperpolarised Xenon-129 at upcoming medical conferences

Polarean's investigational drug/device combination product to be prominently featured in presentations across a wide range of lung diseases

Polarean Imaging plc (AIM: POLX), the medical - imaging technology company, with an investigational drug - device combination product to enhance magnetic resonance imaging (MRI) in pulmonary medicine, announces a number of abstracts and oral presentations highlighting the use of hyperpolarised Xenon-129 ("¹²⁹Xe") will be made by leading academic researchers at the upcoming American Thoracic Society ("ATS 2021") virtual conference from 14-19 May 2021 and the International Society for Magnetic Resonance in Medicine ("ISMRM 2021") virtual conference from 15-20 May 2021.

23 abstracts related to the use of hyperpolarised ¹²⁹Xe were accepted for presentation at ATS 2021, consisting of 8 oral presentations and 15 e-poster presentations. Polarean is also supporting ATS 2021 by hosting a virtual exhibit booth.

Additionally, 34 abstracts related to the use of hyperpolarised ¹²⁹Xe were accepted for presentation at ISMRM 2021, consisting of 7 oral presentations and 27 e-poster presentations. Hyperpolarised ¹²⁹Xe will also be discussed in a symposium on 17 May and in a sunrise session on 18 May. Furthermore, Polarean is supporting ISMRM 2021 by hosting a virtual exhibit booth. 

Richard Hullihen, Chief Executive Officer of Polarean commented:   "We are pleased at the important work being done by leading investigators in the field of functional lung imaging. The data being presented at these key scientific meetings will further add to the body of evidence on hyperpolarised ¹²⁹Xenon, highlighting several areas of unmet needs in current diagnostic modalities. Research of ¹²⁹Xe MRI in interstitial lung disease, long-COVID-19, asthma, COPD and interventional pulmonology procedures are among the presentations that will be showcased."

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 (¹²⁹Xe) as an imaging agent to visualise ventilation. ¹²⁹Xe 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 ¹²⁹Xe 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.
