CAMBRIDGE, Mass., Oct. 26, 2022 (GLOBE NEWSWIRE) -- Biogen Inc. (Nasdaq: BIIB) announced new data on multiple sclerosis (MS) disease measurement and advanced analytics being presented at the 38th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) meeting October 26-28, 2022. These data highlight Biogen’s multi-pronged approach to pursue MS-related digital health research aimed at supporting the development of new treatments, individualizing care, and advancing the understanding of disease heterogeneity.

“Biogen is working to realize a future where multi-dimensional data are leveraged to better characterize and monitor MS disease progression and to predict therapy response at an individual level,” said Shibeshih Belachew, M.D., Ph.D., Head of Science, Biogen Digital Health. “This year’s ECTRIMS presentations represent our ongoing digital health research and highlight progress in developing advanced measurement methods that aim to enhance drug development and personalized care for better patient outcomes.”

Developing Digital Tools for More Precise MS Disease Measurement
Multiple presentations at ECTRIMS highlight the potential for technology to provide new opportunities in disease measurement through digital health technology tools. A poster investigating the relationship between novel measures from a technology-enabled nine-hole peg test called the Manual Dexterity Test (MDT) included 3,525 patients and 44,394 MDT observations. Results suggest that overall MDT time is a reliable measure that correlates with changes in disability progression and quality of life in MS patients and that a new metric of MDT speed yields superior predictive models of disease progression relative to overall MDT time.

Two additional posters analyzed interim data from the DigiToms study [NCT04756700] evaluating a smartphone-based Cognitive Processing Speed (CPS) Test from Konectom™, a mobile application that is intended to be used as a self-assessment tool to objectively quantify motor and cognitive functions. Data demonstrate that CPS score and response time features are sensitive to cognitive impairment and show discriminative validity between people with MS and healthy participants. A second poster outlines differences in three outcome measures of the CPS test when performed with a fixed reference key versus a dynamic reference key, an important element of test design. MDT and Konectom are currently only used in limited research settings.

Applying Machine Learning, Artificial Intelligence and Radiomics to Generate MS Disease Progression Insights
Three presentations at ECTRIMS feature the most recent research from Biogen’s collaboration with TheraPanacea, which aims to develop computer-aided diagnosis software solutions to accelerate drug development and improve patient care using machine learning (ML), artificial intelligence (AI) and radiomics. One poster demonstrates that machine learning and radiomics may extract more information about the heterogeneity observed in MS lesions than is currently possible from a visual read. Nearly 2,400 MRI scans from the ADVANCE and ASCEND Phase 3 clinical trials were retrospectively analyzed, and clusters of acute MS lesions were identified with specific spatial, geometric, and textural patterns. Two additional posters focus on advancing technical capabilities of conventional MRI by using novel ML-AI-based algorithms for MS lesion segmentation.

Advancing Precision Medicine Models Toward Predicting Individual Treatment Response
The ability to more precisely predict how individuals will respond to treatment is needed to advance personalized care and improve patient outcomes. One poster at ECTRIMS highlights analyses using real-world data from 1,600 patients in the MS PATHS (Partners Advancing Technology and Health Solutions) network. Researchers were able to replicate findings from published two-stage precision medicine models that were applied to clinical trial data, providing proof of concept for this analytical methodology using real-world data. The use of two-stage precision medicine models may eventually offer a pathway for predicting and choosing specific treatments in actual practice based on an individual’s own presentation of disease.
