A Study to Evaluate the Efficacy and Safety of Fenebrutinib Compared With Ocrelizumab in Adult Participants With Primary Progressive Multiple Sclerosis

A study to evaluate the efficacy and safety of fenebrutinib on disability progression in adult participants with Primary Progressive Multiple Sclerosis (PPMS). All eligible participants will be randomized 1:1 to either daily oral fenebrutinib (and placebo) or intravenous (IV) ocrelizumab (and placebo) in a blinded fashion through an interactive voice or web-based response system (IxRS). 985 participants were enrolled and recruited globally. Participants who discontinue study medication early or discontinue from the study will not be replaced. The Open-Label Extension (OLE) phase is contingent on a positive benefit-risk result in the Primary Analysis of the study.

Assessing Changes in Multi-parametric MRI in MS Patients Taking Clemastine Fumarate as a Myelin Repair Therapy

The clinical trial is intended to assess for clinical evidence of Clemastine Fumarate as a myelin repair therapy in patients with chronic inflammatory injury-causing demyelination as measured by multi-parametric MRI assessments. No reparative therapies exist for the treatment of multiple sclerosis. Clemastine fumarate was identified along with a series of other antimuscarinic medications as a potential remyelinating agent using the micropillar screen (BIMA) developed at the University of California, San Francisco (UCSF). Following in vivo validation, an FDA IND exemption was granted to investigate clemastine for the treatment of multiple sclerosis in the context of chronic optic neuropathy. That pilot study was recently completed and is the first randomized control trial documenting efficacy for a putative remyelinating agent for the treatment of MS. The preselected primary efficacy endpoint (visual evoked potential) was met and a strong trend to benefit was seen for the principal secondary endpoint assessing function (low contrast visual acuity). That trial number was 13-11577. This study seeks to follow up on that study and examine clemastine fumarate's protective and reparative effects in the context of chronic demyelinating brain lesions as imaged by multi-parametric MRI assessments. The investigators will be assessing the effects of clemastine fumarate as a remyelinating therapy and assessing its effect on MRI metrics of chronic lesions found in patients with a confirmed diagnosis of relapsing-remitting multiple sclerosis. In addition to using conventional multi-parametric MRI assessments, this study will also evaluate a new MRI technique called Ultrashort Echo Time (UTE) MRI to assess the effects of clemastine fumarate as a remyelinating therapy of chronic lesions found in patients with a confirmed diagnosis of relapsing-remitting multiple sclerosis and compare it to the other assessments.

A Study to Evaluate the Efficacy and Safety of Ocrelizumab in Adults With Primary Progressive Multiple Sclerosis

This study will evaluate the efficacy and safety of ocrelizumab (Ocrevus®) compared with placebo in participants with primary progressive multiple sclerosis (PPMS), including participants later in their disease course. This study will consist of the following phases: screening, double-blind treatment, an optional post-double-progression ocrelizumab (PDP OCR) treatment, follow-up 1 (FU1), an optional open-label extension (OLE), and follow-up 2 (FU2).

Cognition Evolution and MRI Markers in PPMS Patients on 2 Years

Cognitive impairment is nowadays more and more recognized as an important feature of the multiple sclerosis (MS) disease. Cognitive disorders frequency in MS is estimated between 40 and 60%. Cognitive impairment affects quality of life and vocational status in MS patients. Until recently, little information was available on the cognitive dysfunction and their evolution that occur in primary progressive multiple sclerosis (PPMS) as compared with relapsing-remitting MS (RRMS). In PPMS pathological studies have shown the importance of cortical demyelination and meningeal inflammation suggesting that the GM alteration could play a major role in the cognitive impairment in this phenotype. The cognitive evolution and the brain tissue alteration at the origin of these difficulties remain poorly understood in PPMS. The use of new techniques for morphological and functional MRI can study the contribution of diffuse White Matter (WM) alteration (probably through disconnexion of relevant network) and diffuse Grey matter (GM) alterations in the cerebral cortex and other structures (the hippocampi, the cerebellum, and the thalami) in cognitive impairment in PPMS patients and on their evolution.

Clinnova-MS: A Prospective Cohort Study of Patients With Multiple Sclerosis (Switzerland)

This prospective cohort study is part of the Clinnova programme and aims to (i) identify clinical imaging and omics characteristics associated with early Multiple Sclerosis (MS) and with transitioning phases to progressive MS, as well as (ii) to investigate digital biomarkers allowing the continuous clinical monitoring of those patients.

MS-ResearchBiomarkerS

This study is being conducted to investigate risk factors for disability progression in Multiple Sclerosis and related disorders (MSRD). The primary goal is to assess whether combining information from visual assessment, blood markers, as well as historical and ongoing longitudinal MRIs of the brain, orbit (the part of the skull where eyes are located), and/or spinal cord can predict changes in quantitative disability measures related to MSRD and neurological disease.
