A Study to Evaluate the Efficacy, Safety and Pharmacokinetics (PK) of a Higher Dose of Ocrelizumab in Adults With Relapsing Multiple Sclerosis (RMS)

ClinConnect Summary

This clinical trial is testing a higher dose of a medication called ocrelizumab in adults with relapsing multiple sclerosis (RMS). The goal is to see if this new higher dose is more effective and safe compared to the standard dose of 600 milligrams that is currently approved. The study involves participants receiving the medication through an intravenous (IV) infusion every 24 weeks and will help researchers understand how well the drug works and how it moves through the body.

To be eligible for this study, participants need to have a confirmed diagnosis of RMS and must have experienced at least two relapses in the past two years, or one relapse in the last year. They should also be neurologically stable for at least 30 days before starting the trial. Participants can expect regular check-ins and assessments throughout the study, including MRI scans and tests to evaluate their health. It's important to note that the trial is currently active but not recruiting new participants at this time. If you're considering participation or want to know more about this type of study, it's best to discuss it with a healthcare provider.

• • Participants must be neurologically stable for at least 30 days prior to randomization and baseline
• • EDSS score, at screening and baseline, from 0 to 5.5 inclusive
• • Average T25FWT score over two trials at screening and over two trials at baseline respectively, up to 150 (inclusive) seconds
• • Average 9HPT score over four trials at screening and over four trials at baseline respectively, up to 250 (inclusive) seconds
• • Documented magnetic resonance imaging (MRI) of brain with abnormalities consistent with MS at screening
• • Participants requiring symptomatic treatment for MS and/or physiotherapy must be treated at a stable dose. No initiation of symptomatic treatment for MS or physiotherapy within 4 weeks of randomization
• • Females of childbearing potential, agreement to remain abstinent or use adequate contraceptive methods
• • Female participants without reproductive potential may be enrolled e.g. if post-menopausal or if surgically sterile
• Exclusion Criteria:
• • History of primary progressive MS at screening
• • Any known or suspected active infection at screening or baseline (except nailbed infections), or any major episode of infection requiring hospitalization or treatment with IV antimicrobials within 8 weeks or treatment with oral antimicrobials within 2 weeks, prior to and during screening
• • History of confirmed or suspected progressive multifocal leukoencephalopathy
• • History of cancer, including hematologic malignancy and solid tumors, within 10 years of screening
• • Immunocompromised state
• • Receipt of a live or live-attenuated vaccine within 6 weeks prior to randomization
• • Inability to complete an MRI or contraindication to gadolinium administration
• • Contraindications to mandatory pre-medications for infusion-related reaction (IRRs)
• • Known presence of other neurologic disorders that could interfere with the diagnosis of MS or assessments of efficacy and/or safety during the study
• • Any concomitant disease that may require chronic treatment with systemic corticosteroids or immunosuppressants during the course of the study
• • Significant, uncontrolled disease that may preclude participant from participating in the study
• • History of or currently active primary or secondary, non-drug-related, immunodeficiency
• • Pregnant or breastfeeding or intending to become pregnant
• • Lack of peripheral venous access
• • History of alcohol or other drug abuse within 12 months prior to screening
• • Treatment with any investigational agent within 24 weeks prior to screening or treatment with any experimental procedure for MS
• • Previous use of anti- cluster of differentiation 20 (CD20s) (including ocrelizumab), unless the last infusion was more than 2 years before screening, B-cell count is normal, and the stop of the treatment was not motivated by safety reasons or lack of efficacy

If the washout requirements are not described in the applicable local label, then the wash out period must be five times the half-life of the medication
• • Any previous treatment with bone marrow transplantation and hematopoietic stem cell transplantation
• • Any previous history of transplantation or anti-rejection therapy
• • Treatment with IV immunoglobulin (Ig) or plasmapheresis within 12 weeks prior to randomization
• • Systemic corticosteroid therapy within 4 weeks prior to screening
• • Positive screening tests for active, latent, or inadequately treated hepatitis B
• • Sensitivity or intolerance to any ingredient (including excipients) of ocrelizumab
• • Any additional exclusionary criterion as per ocrelizumab local label, if more stringent than the above
