Power estimation for non-standardized multisite studies
2016
A concern for researchers planning multisite studies is that scanner and T1-weighted sequence-related biases on regional volumes could overshadow true effects, especially for studies with a heterogeneous set of scanners and sequences. Current approaches attempt to harmonize data by standardizing hardware, pulse sequences, and protocols, or by calibrating across sites using phantom-based corrections to ensure the same raw image intensities. We propose to avoid harmonization and phantom-based correction entirely. We hypothesized that the bias of estimated regional volumes is scaled between sites due to the contrast and gradient distortion differences between scanners and sequences. Given this…
Clinical Efficacy of Laquinimod for the Treatment of Multiple Sclerosis; Pooled Analyses from the ALLEGRO and BRAVO Phase III Trials (S01.007)
2012
Objective: The current report provides detail on pooled analyses assessing the effect of laquinimod on relapse, disability, and brain atrophy measures from the recently completed phase III trials ALLEGRO and BRAVO. Background Laquinimod is an oral, CNS acting immunomodulator in development for the treatment of multiple sclerosis. Its impact on disability progression and brain atrophy, two indices of longterm outcome for patients with multiple sclerosis (MS) are being studied in its phase III trials. Design/Methods: MS patients (N=2437) were randomized to laquinimod (n=984) or placebo (n = 1006). In both trials, patients underwent neurological examinations including the Expanded Disability S…
Serum neurofilament light chain is a biomarker of acute and chronic neuronal damage in early multiple sclerosis.
2018
Background: Monitoring neuronal injury remains one key challenge in early relapsing-remitting multiple sclerosis (RRMS) patients. Upon axonal damage, neurofilament – a major component of the neuro-axonal cytoskeleton – is released into the cerebrospinal fluid (CSF) and subsequently peripheral blood. Objective: To investigate the relevance of serum neurofilament light chain (sNfL) for acute and chronic axonal damage in early RRMS. Methods: sNfL levels were determined in 74 patients (63 therapy-naive) with recently diagnosed clinically isolated syndrome (CIS) or RRMS using Single Molecule Array technology. Standardized 3 T magnetic resonance imaging (MRI) was performed at baseline and 1–3 con…
ECTRIMS/EAN guideline on the pharmacological treatment of people with multiple sclerosis.
2018
Background and purpose: Multiple sclerosis (MS) is a complex disease of the central nervous system. As new drugs are becoming available, knowledge on diagnosis and treatment must continuously evolve. There is therefore a need for a reference tool compiling current data on benefit and safety, to aid professionals in treatment decisions and use of resources across Europe. The European Committee of Treatment and Research in Multiple Sclerosis (ECTRIMS) and the European Academy of Neurology (EAN) have joined forces to meet this need. The objective was to develop an evidence-based clinical practice guideline for the pharmacological treatment of people with MS to guide healthcare professionals in…
