Relapsing Multiple Sclerosis

The primary purpose of this study is to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of ublituximab in participants ages 10 to less than (\<)18 years and body weight greater than or equal to (≥)25 kilograms (kg) to less than or equal to (≤)40 kg with RMS (Part A) and to evaluate the non-inferiority of ublituximab compared with fingolimod in pediatric RMS participants with body weight ≥ 25 kg (Part B). The study will further evaluate long-term safety and efficacy of ublituximab in RMS in pediatric participants during its extension period (Part C).

The primary objective of the lactation study is to characterize the presence and concentration of BRIUMVI™ in breast milk among breastfeeding participants who receive BRIUMVI™ therapeutically for the treatment of relapsing forms of multiple sclerosis (RMS).

The primary purpose of this phase 3b study is to assess the efficacy of a modified regimen of ublituximab in participants with relapsing multiple sclerosis (RMS) as measured by T1 Gadolinium (Gd)-enhancing lesions in Part A; PK in Part B along with efficacy of ublituximab as measured by T1 Gd-enhancing lesions in participants who had a suboptimal experience on prior anti-CD20 therapy in Part C. The study consists of 3 parts: Part A is single-armed and open-label, Part B is randomized, double-blind, placebo-controlled, and Part C is single-armed and open-label.

This open label, single arm study will evaluate the PK and PD effects of fenebrutinib in children and adolescents with RMS aged between 10 and \< 18 years. This study consists of a Dose Exploration Period and an Optional Extension Period. Eligible participants may choose to continue treatment with fenebrutinib in the optional extension period after completing the dose exploration period.

The purpose of this Phase 3b study is to assess the efficacy, safety and tolerability of remibrutinib after switching from ocrelizumab and compared to continuous ocrelizumab treatment, in patients living with relapsing multiple sclerosis (plwRMS).

The purpose of this study is to assess the safety, tolerability, pharmacokinetics (PK) and, pharmacodynamics (PD) of subcutaneously administered RO7845860 in participants with relapsing multiple sclerosis (RMS).

This is an open-label, multi-center, non-confirmatory study to assess the safety, efficacy, and cellular kinetics of YTB323 in approximately 28 participants with Relapsing Multiple Sclerosis (RMS) with breakthrough disease activity during previous treatment with a highly efficacious therapy (BD-HET). The study design utilizes an ascending single dose design consisting of 3 sentinel cohorts followed by an expansion cohort.

This is an observational, non-interventional, multicenter, open-label study in patients being treated with any approved injectable or selected oral DMT for RMS in Germany. Prospective, primary data will be collected via questionnaires and an electronic case report form (eCRF) over a period of up to four years. Additionally, medical history of participants will be collected including disease duration, laboratory values, EDSS, MRI parameters and relapses.

The purpose of this study is to evaluate safety, effiectiveness, and to gain insight into the treatment experience of participants prescribed BRIUMVI® (ublituximab-xiiy) in the real-world setting

This non-interventional study will compare the effect of Ofatumumab treatment between patients that began Ofatumumab within the 3 years after Multiple Sclerosis diagnosis and patients that began Ofatumumab with more than 3 years of Multiple Sclerosis diagnosis in a real-world setting in Portugal.

This is a multi-center prospective rater-masked (blinded) randomized controlled trial of 156 participants, comparing the treatment strategy of Autologous Hematopoietic Stem Cell Transplantation (AHSCT) to the treatment strategy of Best Available Therapy (BAT) for treatment-resistant relapsing multiple sclerosis (MS). Participants will be randomized at a 1 to 1 (1:1) ratio. All participants will be followed for 72 months after randomization (Day 0, Visit 0).

A multi-center pilot study to evaluate safety and efficacy of ozanimod as de-escalation therapy in clinically stable MS patients previously treated with anti-CD20 therapy.

The goal of this clinical trial is to evaluate the efficacy and safety\] in \[subjects diagnosed with RMS according to the 2017 McDonald criteria, including clinically isolated syndrome (CIS), relapsing-remitting multiple sclerosis (RRMS), and active secondary progressive multiple sclerosis (SPMS). The main questions it aims to answer are: \[Question 1\] The efficacy of dimethyl fumarate enteric-coated capsules in the treatment of RMS. \[Question 2\] The safety of dimethyl fumarate enteric-coated capsules in the treatment of RMS. Participants will: Eligible 50 RMS patients will orally take dimethyl fumarate enteric-coated capsules during treatment, with an initial dose of 120 mg twice daily for 7 days, followed by a maintenance dose of 240 mg twice daily for 48 weeks. The annualized relapse rate (ARR) at Week 48 will be observed.
