Clinical Trial Summary

Diagnostic investigations in paediatric respiratory and sleep medicine are often challenging due to patient size (due to prematurity), tolerability, and compliance with "gold standard equipment". Children with sensory/behavioural issues, at increased risk of sleep disordered breathing (SDB), often find tolerating standard diagnostic equipment difficult. There is a need to develop non-invasive, wireless, devices designed for the paediatric population. Devices must address health in-equalities as high-risk children, with low birth weights, genetic syndromes, or complex neuro-disabilities, are often unable to undergo current investigations, particularly in sleep medicine. Prompt and accurate diagnosis of SDB is important to facilitate early intervention and improve outcomes

Infants in the neonatal period can have immature breathing control which manifests as excessive central breathing pauses, apnoea's, whilst asleep requiring oxygen therapy. There is also a risk to newborn term infants of sudden unexpected neonatal collapse, even in "low risk" babies. Diagnosis of breathing issues in babies can be challenging since babies are often too small for standard monitoring equipment. Effective monitoring and appropriate treatment of apnoea's has been shown to improve prognosis in terms of 5-year mortality and neurodevelopmental outcomes.

This observational study is part of a phased clinical program of research that aims to validate a small wearable biosensor developed by PneumoWave Ltd in a paediatric clinical setting with the overall primary endpoints of monitoring and assessing respiratory pattern as an aid to sleep diagnostics, and as a device to monitor apnoea in neonatal patients.

Clinical Trial Description

Sleep diagnostics

The investigation of sleep disordered breathing (SDB) in children can be challenging given the requirement to apply sensors/bands that measure physiological changes as part of a cardiorespiratory sleep study (CR-poly). Children with sensory/behavioural issues, who have an increased risk of SDB, often find tolerability of standard diagnostic equipment difficult. Similarly, the usefulness is limited in low weight infants. Thus, there is a need to investigate novel devices which may provide sleep diagnostic information when a CR-poly may be inappropriate or challenging. A wearable respiratory rate (RR)/effort sensor can provide continuous remote monitoring of patients and may identify abnormal breathing patterns associated with SDB.

Central Apnoea & abnormal breathing patterns in neonatal patients

Babies born prematurely can often have apnoea of prematurity requiring caffeine therapy. Similarly, term (or term corrected) infants can have immature breathing control which manifests as excessive central breathing pauses whilst asleep requiring oxygen therapy. There is also a risk to newborn term infants of sudden unexpected collapse, even in "low risk" babies. Diagnosis of breathing issues in babies can be challenging since babies are often too small for standard CR-poly equipment. We aim to use the Pneumowave sensor alongside other diagnostic equipment to assess the feasibility of using this novel sensor to aid diagnosis in the post-natal period and pre-discharge from neonatal unit. Currently, newborn infants receive no standard respiratory monitoring following delivery. We aim to use the Pneumowave sensor as an indicator of altered respiratory patterns in this patient group.

PneumoWave Ltd Device

PneumoWave Ltd is developing a small, chest-worn, ambulatory biosensor ("Pneumowave") to detect changes in a range of respiratory metrics. This physical monitor is linked wirelessly via Bluetooth to a central monitoring systems in the form of a mobile platform app (running on a smartphone or tablet). Real-time data analysis, event detection and alert response management algorithms will eventually be are located in the hub, mobile app - they are currently in the cloud depending on the device configuration.

The proposed technology, Pneumowave device, will be used in the diagnosis, treatment and monitoring of illness, and therefore must be regulated as a Class 2 Medical Device in accordance with the regulatory framework in each country of use. To achieve this, PneumoWave Ltd first intends to develop a device capable of detecting adverse respiratory events in the hospital setting where immediate attendance to alerts is available. Further technical development will be required prior to the submission for regulatory approval of a device that is suitable for use in the community where there may be a longer time before a response is activated.

This hospital study aims to compare the PneumoWave Ltd monitoring system with the current clinical standard for such monitoring in a range of hospital-based clinical services.

The studies will observe three distinct patient groups:

Group 1: Patients attending for an overnight CR-poly

• A subgroup of these patients will take the Pneumowave device home for extended home-based sleep studies for up to 7 nights.

Group 2: Patients who are at risk of apnoea in the neonatal unit ;
