Real World Effectiveness of Natalizumab Extended Interval Dosing in a French Cohort

Natalizumab (NTZ) use in Multiple Sclerosis (MS) in highly active patients has been largely established during the last Rationale 10 years in both clinical trials and real-world practice. Along with its efficacy, NTZ use has been limited by potential risk of progressive multifocal leukoencephalopathy (PML). Thus, several studies have tried to assess how to minimize this risk. One suggested approach is to move from the standard interval dose (SID) of 4 weeks to an extended interval dose (EID) of 5 weeks or longer. Extending the dosing interval of NTZ has been practiced by some physicians with the intention of improving the benefit/risk of the treatment by reducing the exposure-dependent risk of progressive multifocal leukoencephalopathy (PML) while maintaining efficacy. We propose to retrospectively analyze data from clinical records coming from RRMS patients treated in France at 5 different centers; Caen, Nice, Bobigny and Toulouse hospitals as well as Percy Military Hospital, to evaluate the effectiveness of natalizumab EID in subjects who have previously been treated with natalizumab SID for 12 months, in relation to continued SID treatment. In the clinical practice of these centers, patients are shifted after minimum 12 months under SID to an EID of 6 weeks regardless antibody JC serum status. Clinical, magnetic resonance imaging (MRI) and serum anti-JCV antibody status data are collected when available. The objective of this study is to assess the efficacy in term of ARR and safety.

Sensitivity of Motor Assessment in MS - a Prospective Cohort Study

The study explores the application of marker-less motion analysis (visual-perceptive computing, VPC) using a consumer grade infrared and video camera (Microsoft Kinect) for clinical assessment in MS. It includes as the primary outcomes a short assessment battery of simple motor tasks (PASS-MS) that can be performed in front of the sensor after standard oral instructions given by the operator. For each task, the sensor data are transformed into a set of kinematic parameters that may be used as motor outcome reflecting specific neurological dysfunction. For validation against both clinical and patient-reported outcomes as well as MRI findings, we here prospectively investigate a large cohort of patients with multiple sclerosis. This will allow to determine the usefulness of the various kinematic parameters generated and to define a reduced set of the most meaningful parameters for potential use in future MS trials. Data on repeatability and benchmarks for clinically relevant change are essential to interpret test results and, more importantly, changes thereof. Further, this prospective study will yield estimates of progression rates that are required for planning future studies using this motion analysis tool and assessment battery as an outcome. The study is designed to obtain benchmarks for sensitivity and clinical responsiveness. Primary analysis aims to answer the question: Does the SMSW - Maximum Speed worsen with disease progression established as confirmed disability progression based on EDSS after 24 months (defined as 1 step increase in EDSS ≤ 5.5 and 0.5 step in EDSS > 5.5)?
