About Polarean (

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 membrane, 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. The Group received a complete response letter on 5 October 2021. On 30 March 2022, the Company filed the resubmission of its NDA with the US FDA and has received a PDUFA date of Sept 30, 2022.

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.
