[{"type":"text","content":"\n\n23 May 2023\n \nPureTech Health plc\n \nPureTech Founded Entity Sonde Health Announces Respiratory Responsive Vocal Biomarker Tool Differentiates Patients with Respiratory Conditions from Healthy Individuals\n \nStudy published in JMIR suggests that RRVB tool could help to pre-screen acute respiratory infections, including asymptomatic COVID-19\n \nPureTech Health plc (Nasdaq: PRTC, LSE: PRTC) (\"PureTech\" or the \"Company\"), a clinical-stage biotherapeutics company, noted today that its Founded Entity, Sonde Health, a health technology company committed to bringing accessible health monitoring to everyone, has revealed new research that demonstrates the ability of its respiratory responsive vocal biomarker (RRVB) machine learning model to differentiate patients with COVID-19 from healthy individuals with about 70% accuracy.\n \nThe RRVB tool had already shown strong performance in differentiating patients with asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease, and cough from healthy individuals. In the new study, conducted in collaboration with Montefiore Health System, Brigham and Women's Hospital, UC San Diego Health System, and Deenanath Mangeshkar Hospital in Pune, India, the model achieved 73% sensitivity and 63% specificity for the entire COVID-19 population (97 patients), and it detected 66% of asymptomatic COVID-19 subjects (46 patients) using only a six-second recording of an \"ahh\" vowel sound on patient smartphones. These findings suggest the tool could help uncover respiratory conditions before symptoms arise.\n \nThe peer-reviewed study, which was published in the Journal of Medical Internet Research (JMIR), suggests the RRVB tool could serve as a pre-screening tool for acute respiratory infection and pave the way for the development of voice-based tools for future disease detection and monitoring applications.\n \nThe full text of the announcement from Sonde is as follows: \n \nSonde Health's Respiratory Responsive Vocal Biomarker Tool Differentiates Patients with Respiratory Conditions from Healthy Individuals\n \nStudy published in JMIR suggests that RRVB tool could help to pre-screen acute respiratory infections, including asymptomatic COVID-19\n \nBOSTON, MA - May 23, 2023 - Sonde Health, a health technology company com...
