Subcutaneous ocrelizumab in multiple sclerosis: Results of the Phase 1b OCARINA I study.

Objective: Subcutaneous ocrelizumab is being developed to provide treatment flexibility and additional choice to patients with multiple sclerosis. OCARINA I (NCT03972306) is an open-label, multicenter, Phase 1b, dose-finding study to investigate the pharmacokinetics, safety, tolerability, and immunogenicity of subcutaneous ocrelizumab and to select a dose for the Phase 3 OCARINA II study (NCT05232825).

Methods: Patients with relapsing or primary progressive multiple sclerosis (aged 18-65 years; Expanded Disability Status Scale score 0.

Podcast on Identifying and Understanding Barriers to Care in Underserved Populations With MS in the United States.

Multiple sclerosis (MS) can affect people from all racial and ethnic backgrounds, but, historically, the incidence of MS in the United States was thought to be highest in White individuals. More recent data suggest that the incidence of MS in Black or African American individuals is comparable to that in White individuals. In Hispanic or Latino individuals, incidence of MS is lower, but age of onset may be earlier compared with White individuals.

Results from a multicenter, randomized, double-blind, placebo-controlled study of repository corticotropin injection for multiple sclerosis relapse that did not adequately respond to corticosteroids.

Introduction: About 20%-35% of multiple sclerosis (MS) patients fail to respond to high-dose corticosteroids during a relapse. Repository corticotropin injection (RCI, Acthar Gel) is a naturally sourced complex mixture of adrenocorticotropic hormone analogs and pituitary peptides that has anti-inflammatory and immunomodulatory effects.

Aims: The study objective was to determine the efficacy and safety of RCI in patients with MS relapse that inadequately responded to corticosteroids.

Progressive myelopathy in myelin oligodendrocyte glycoprotein antibody-associated disease: A new mimicker of progressive multiple sclerosis?

Background MOG-IgG-associated disease (MOGAD) in adults typically presents as a monophasic or relapsing optic, spinal, or opticospinal neuroinflammatory syndrome. Current recommendations discourage testing for MOG-IgG in patients with clinical or paraclinical findings more typical of MS, or in patients with a progressive clinical course. However, this approach may impede identification of the full phenotypic spectrum of this recently described disorder.

Safety evaluation of shorter infusion for ocrelizumab in a substudy of the Phase IIIb CHORDS trial.

The CHORDS trial evaluated ocrelizumab (OCR) in patients with relapsing-remitting multiple sclerosis who had a suboptimal response to previous disease-modifying treatment. The objective of the present study was to assess the safety of shorter OCR infusions in a substudy of CHORDS. After completing four doses of OCR per initial US prescribing recommendations in the main study, participants in the substudy (N = 129) received a fifth dose over a 2-h duration (vs.

Neuroimaging of demyelination and remyelination models.

Small-animal magnetic resonance imaging is becoming an increasingly utilized noninvasive tool in the study of animal models of MS including the most commonly used autoimmune, viral, and toxic models. Because most MS models are induced in rodents with brains and spinal cords of a smaller magnitude than humans, small-animal MRI must accomplish much higher resolution acquisition in order to generate useful data. In this review, we discuss key aspects and important differences between high field strength experimental and human MRI.
