ResApp Health Limited and Phenix Health Pty Ltd. have entered into a joint development agreement (JDA) to integrate ResApp's acute respiratory diagnostic test, ResAppDx-EU into Phenix's telehealth smartphone app. Respiratory disease is involved in up to half of all telehealth consultations and ResAppDx-EU is the only solution for accurately diagnosing respiratory disease during a telehealth consultation that does not require additional hardware. ResAppDx-EU is a software application used by clinicians to diagnose the most common respiratory diseases. The software uses machine learning algorithms that analyse a patient's cough sounds to diagnose lower respiratory tract diseases such as pneumonia and asthma exacerbations. ResAppDx-EU is CE Marked in the European Union and Therapeutics Goods Administration (TGA) approved in Australia. Phenix and ResApp will work together under the JDA for the next three months to integrate ResAppDx-EU into Phenix's telehealth app. During this time, ResApp and Phenix will negotiate the specifics of the fee-per-test payment model of using ResAppDx-EU on the Phenix App.
