Resapp Health Ltd (ASX:RAP) is planning to restart the U.S. paediatric clinical study of its “ResAppDx” app to detect respiratory diseases, this U.S. winter.
The company’s smartphone app works by using algorithms to analyse the sound of a patient’s cough and provide a diagnosis.
To improve the data-gathering element of the study, ResApp will now be regularly present onsite conducting clinical study team training, reviewing enrolment procedures and verifying data.
This is to help ensure that high-quality cough sounds are collected as early as possible during the patient’s hospital visit and prior to any treatment known to affect cough analysis.
Furthermore, an improved audio recording smartphone application incorporating built-in checklists, automated background noise estimation and additional visual aids will be deployed.
This is to support the data collection teams and eliminate inappropriate collection of cough data with background noise contamination.
However, Doctors Without Borders is not proceeding with its evaluation of ResAppDx, following the review of the issues identified in Resapp’s earlier study and the high cost of keeping the project open.
ResApp and Doctors Without Borders will maintain their collaborative relationship and seek opportunities for field testing the technology once the issues have been resolved.
All sites have reaffirmed their intention to rerun the updated study and are targeting to restart the study before the beginning of the U.S. winter season.
