FDA submission to expand minimum age for XENOVIEW™

Polarean Imaging plc (AIM: POLX), a commercial-stage medical device leader in advanced Magnetic Resonance Imaging ("MRI") of lung function, announces that it has submitted a New Drug Application ("NDA") supplement to the US Food and Drug Administration ("FDA"), to allow the administration of XENOVIEW™ to paediatric patients aged six years and older. This supplement includes updates to the HPX Polarisation Measurement Station and new XENOVIEW™ Dose Delivery Bag sizes.

Currently XENOVIEW™, prepared from the Xenon Xe 129 Gas Blend, is a hyperpolarised contrast agent indicated for use with magnetic resonance imaging (MRI) for evaluation of lung ventilation in adults and paediatric patients aged 12 years and older.

Christopher von Jako, Ph.D, Chief Executive Officer of Polarean, said: "I am pleased to have submitted our NDA supplement to the FDA to expand the minimum age of XENOVIEW™ to paediatric patients six years and older. If granted, this will allow our technology to help even more children with chronic lung conditions and their clinicians, allowing for better management of their disease. I look forward to further updating the market in due course."

XENOVIEW IMPORTANT SAFETY INFORMATION 

Indication

XENOVIEW™, prepared from the Xenon Xe 129 Gas Blend, is a hyperpolarized contrast agent indicated for use with magnetic resonance imaging (MRI) for evaluation of lung ventilation in adults and pediatric patients aged 12 years and older.

Limitations of Use

XENOVIEW has not been evaluated for use with lung perfusion imaging.

CONTRAINDICATIONS

None.

Warnings and Precautions

Risk of Decreased Image Quality from Supplemental Oxygen: Supplemental oxygen administered simultaneously with XENOVIEW inhalation can cause degradation of image quality. For patients on supplemental oxygen, withhold oxygen inhalation for two breaths prior to XENOVIEW inhalation, and resume oxygen inhalation immediately following the imaging breath hold.

Risk of Transient Hypoxia: Inhalation of an anoxic gas such as XENOVIEW may cause transient hypoxemia in susceptible patients. Monitor all patients for oxygen desaturation and symptoms of hypoxemia and treat as clinically indicated.

Adverse Reactions 

Adverse Reactions in Adult Patients: The adverse reactions (> one patient) in efficacy trials were oropharyngeal pain, headache, and dizziness.  Adverse Reactions in Pediatric and Adolescent Patients: In published literature in pediatric patients aged 6 to 18, transient adverse reactions were reported: blood oxygen desaturation, heart rate elevation, numbness, tingling, dizziness, and euphoria. In at least one published study of pediatric patients aged 6 to 18 years, transient decrease in SpO2% and transient increase in heart rate was reported following hyperpolarized xenon Xe 129 administration. XENOVIEW is not approved for use in pediatric patients less than 12 years of age.
