Winterlight is developing speech-based digital biomarkers to monitor disease progression in patients with FTD in collaboration with Alector

TORONTO, July 9, 2019 /PRNewswire/ - Winterlight Labs Inc, a company that develops speech-based digital biomarkers for neuropsychiatric disorders, today announced it is developing vocal biomarkers for monitoring disease progression in frontotemporal dementia (FTD) patients in collaboration with Alector, a biotechnology company developing therapeutics for neurodegeneration.

Central nervous system (CNS) disorders such as Alzheimer's disease, schizophrenia and depression are associated with changes in speech - both in the sound and content. Objectively measuring and analyzing speech changes using machine learning and computational linguistics is a novel approach to measuring disease severity and could be a more sensitive method for tracking disease progression. This approach could help physicians and pharmaceutical companies detect treatment efficacy more quickly and with a higher degree of precision compared to current pen-and-paper gold-standard assessments. FTD is a rare and heterogenous group of CNS disorders that result in progressive impairments in personality, behaviour and language.

Winterlight and Alector are deploying Winterlight's speech-based digital biomarker across two projects. The first is in an on-going year-long observational study in participants with FTD. In this study, participants are being assessed remotely by a caregiver using Winterlight's tablet-based assessment, eliminating the need to visit a clinic.

Preliminary data from the observational study indicates that participants with primary progressive aphasia, one of two variants of FTD, use simpler words and grammar and are less articulate than age-matched controls. The data from this study are intended to help develop FTD-specific digital biomarkers that may be used as an exploratory endpoint in Alector's upcoming Phase 2 clinical trial for AL001.
