Active clinical trials for "Multiple Sclerosis, Chronic Progressive"

Primary Objective: To assess the long-term safety of GZ402668 in patients with multiple sclerosis (MS) who received prior treatment during the TDU13475 or TDU14981 studies. Secondary Objectives: To assess the pharmacokinetics of GZ402668 in patients with MS. To assess the pharmacodynamics of GZ402668 in patients with MS. To assess the immunogenicity of GZ402668 in patients with MS.

This study will look at the blood and cerebrospinal fluid of consented participants who either have early stage multiple sclerosis (clinically isolated syndrome) or who have later stage (secondary progressive multiple sclerosis), or participants who do not have any neurological or autoimmune illness. Biomarkers and microRNA will be assessed for group differences.

Scientific background: Growing awareness and accumulating data regarding the cognitive impairment and its progression in multiple sclerosis (MS) patients has received an important place in neurological research in the last decade.

This study was a retrospective, non-interventional, longitudinal, descriptive study. This study did not have a key underlying hypothesis, rather it was designed to explore the onboarding and adherence of SPMS patients in Australia to Mayzent (siponimod) treatment. Initiating siponimod involves pre-screen tests, including a CYP2C9 genotype test to determine siponimod maintenance dosing, and patients underwent a 6-day titration prior to maintenance. The MSGo platform was developed to support onboarding. It is an integrated digital platform that functions as a patient support service.

The primary goal of the research cohort is to facilitate patient access to clinical trials testing new therapeutic interventions, or access to second- line treatments. Secondary objectives of the research cohort study are to obtain detailed clinical phenotyping and immunological analysis of blood samples, aiming to identify and validate biomarkers of disease activity and response to treatment and prognostic markers.

The investigators propose to use the novel SV2a-PET ligand, [F-18]SDM-8 to assess synaptic density in progressive MS (including primary progressive multiple sclerosis (PPMS) and secondary progressive multiple sclerosis (SPMS)) as compared to relapsing-remitting multiple sclerosis (RRMS) patients and healthy controls, given its improved imaging characteristics and potential for large scale applicability. The specific aims of the study are: Aim 1: To compare the cortical and subcortical grey matter synaptic density in progressive MS patients, patients with relapsing-remitting MS, and healthy subjects, using a novel [F-18] labeled synaptic density PET ligand, [F-18]SDM8, also known as [F-18]SynvesT-1. Aim 2: To compare the relationship of synaptic density PET and standard 3T MRI measures including global and regional brain atrophy and lesion load with clinical measures of physical disability, cognitive impairment, fatigue and depression in MS patients. Aim 3: To assess the relationship of synaptic density PET with serum neurofilament light chain (NfL) and with serum measurements of inflammatory markers, IL-1β, TNF-α, IL-6, MCP-1 (Monocyte Chemoattractant Protein-1) and MIF-1 (Macrophage Migration Inhibitory Factor-1).

This study is designed to identify a brief screening evaluation for MS patients that is sensitive and specific to the MS population and which correlates with the findings of our standard-of-care neuropsychological assessments.

Using a technique called adaptive optics imaging applied on retina, investigators aim to gain access to vascular changes that could occur early in the course of Multiple Sclerosis (MS) and which could reflect vascular changes occurring along the optic nerve of the brain parenchyma. Indeed, our team has been able to develop a quantitative method to measure the perivascular infiltrate in the retina of patients with various inflammatory retinal disease. It has been observed in MS patients that this perivascular infiltrate can also be detected in the retina. However, its distribution across MS phenotypes (relapsing or progressive MS, with and without optic neuritis) is still unknown.

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)?

This study is a case-control study, involving persons with progressive multiple sclerosis and healthy controls. The study contains 1 descriptive and 3 experimental sessions. In the descriptive session, participant's clinical motor and cognitive functions are collected. In the first experimental session, participant's beat perception and synchronisation abilities is examined within a finger tapping paradigm. In the following experimental sessions participants synchronsiation abilities is examined during walking paradigms, to music and metronomes, with period and phase auditory manipulations. In the latter twp sessions, apart from outcome measures of synchronization the following will be collected as well: brain activity using EEG recordings, spatio-temporal gait parameters, perceived fatigue, perceived motivation and perceived speed of walking.
