Quantifying the risk of disease reactivation after interferon and glatiramer acetate discontinuation in multiple sclerosis: The VIAADISC score

Abstract: Background and purpose There is a lack of evidence guiding discontinuation of disease‐modifying therapy (DMT) in relapsing multiple sclerosis (RMS). Thus, the objective of this study was to generate and validate a risk score for disease reactivation after DMT discontinuation in RMS. Methods We drew a generation and validation dataset from two separate prospectively collected observational databases including RMS patients who received interferon‐β or glatiramer acetate for ≥12 months, then discontinued DMT for … Show more

“…Therefore, age and disease activity are drivers of outcomes of DMT discontinuation. The Vienna-Innsbruck DMT discontinuation score predicts risk of disease reactivation after discontinuing glatiramer acetate or beta-interferons using a weighted calculation based on age, disease activity on MRI (≥3 new/enlarged T2 lesions or ≥1 gadolinium-enhancing lesion), and duration of stability (years since relapse or EDSS change) ( 24 ). In that study, patients age <45 years had a HR 4.3 (2.5, 7.1), p < 0.001 and patients age ≥45 and <55 years HR 2.1 (1.4, 3.8), p < 0.001, as compared to patients ≥55 years.…”

“…The characteristics of the study cohorts with respect to age at conception, disease duration, and disease activity are in line with other cohorts presented in the literature suggesting generalizability of our results ( 3 , 4 , 7 , 10 , 23 ). Another strength is the robust and standardized statistical approach to generation and validation of the risk score ( 16 , 19 , 20 ).…”

“…As a kind of prediction model, prognostic models focus on the probability of disease recurrence, death, disability, and complications in the future. Several prediction models have been established for predicting the outcome of CNS demyelinating diseases, including Susan's prediction model, 135 the VIAADISC score model, 136 and Seery's prognostic model 137 . Susan's prediction model focused on the prediction of quality of life in adults with MS based on disease‐related risk factors and protective factors.…”
