Phase 3
Active, not recruiting
Conditions
Multiple Sclerosis
Interventions
Registration Number
NCT03599245
Lead Sponsor
Hoffmann-La Roche
Brief Summary

This extension study will evaluate the effectiveness and safety of ocrelizumab in multiple sclerosis (MS) participants who were previously enrolled in a F. Hoffmann-La Roche (Roche) sponsored ocrelizumab phase IIIb/IV trial (i.e. the Parent, P-trial).

Detailed Description

This is a single arm, open label, multicenter extension study in participants who completed treatment period with ocrelizumab in the Roche P-trials. Participants will receive treatment with ocrelizumab as single 600 mg infusions every 24 weeks for two years.

Primary Outcome Measures
NameTimeMethod
Mean change from inclusion in parent study in EDSS score over the course of the treatmentUp to 2 years
Time to onset of CDP sustained for at least 24 weeks and for at least 48 weeksUp to 2 Years
Percentage of participants who have confirmed disability improvement (CDI), CDP for at least 24 weeks and for at least 48 weeks yearly and over the duration of the treatmentUp to 2 years
Percentage of participants who have improved, stable or worsened disability compared with baselineUp to 2 years

Improved, stable or worsened disability is measured by expanded disability status scale (EDSS) (annually/by epoch and over duration of the study) Stable EDSS is defined as EDSS change +/- 0.5. Worsening is \> 0.5 increase of EDSS, Improvement is \>0.5 decrease of EDSS

Time to 20% increase in timed 25-foot walk test (T25FWT)Up to 2 years

Time to 20% increase in timed nine-hole peg test (9HPT) sustained for at least 24 weeks and for at least 48 weeks, and proportion of patients achieving a sustained increase assessed yearly and at the end treatment

Secondary Outcome Measures
NameTimeMethod
Time to first protocol-defined event of disease activityUp to 2 Years
Time to first relapseUp to 2 Years
Annualized relapse rateUp to 2 Years
Percentage of participants relapse free, yearly and over the course of the treatmentUp to 2 Years
Percentage of participants with no evidence of protocol-defined disease activity (NEDA) yearly and over the duration of the treatmentUp to 2 Years

Disease activity is defined as at least one the following events: protocol-defined relapse; 24 weeks CDP based on increases in EDSS; a T1 Gadolinium (Gd)-enhanced lesion; or a new and/or enlarging T2 hyperintense lesion on magnetic resonance imaging (MRI).

Percentage of participants with no evidence of progression (NEP)Up to 2 Years

NEP is defined as no progression sustained for at least 24 weeks on all of the following three components (CDP; 20% increase in timed T25FWT; 20% increase in timed 9HPT yearly and over the course of the treatment

Presence and evolution of leptomeningeal follicles as detected by MRIUp to 2 Years
Percentage of participants with no evidence of progression sustained for at least 24 weeks and no active disease (NEPAD)Up to 2 Years

NEPAD is defined as no progression on all of the three components of NEP (CDP, T25FWT, 9HPT), no new relapse and no enlarging or new T2 or T1 Gd-enhancing lesion yearly and over the course of the treatment

Change from baseline in cognitive performance as measured by the Symbol digit modalities test (SDMT)Up to 2 Years
Total number of T1 Gd-enhancing lesions as detected by brain MRI over timeUp to 2 Years
Total number of new and/or enlarging T2 lesion as detected by brain MRI over timeUp to 2 Years
Change in total T1 hypointense lesion volume over timeUp to 2 Years
Participant reported outcomes: SymptoMScreen ScoreUp to 2 Years
Participant reported outcomes: Quality of life (QoL) (Multiple Sclerosis Impact Scale [MSIS]-29)Up to 2 Years
Percentage of Participants with Adverse EventsUp to 2 Years
Total number of fluid-attenuated inversion-recovery (FLAIR) late enhancing lesions as detected by brain MRI over timeUp to 2 Years
Change in brain volume (grey and white matter) as detected by brain MRI over timeUp to 2 Years
Time to treatment discontinuation/switchUp to 2 Years
Participant reported outcomes: Employment status (Work Productivity and Activity Impairment Questionnaire [WPAI])Up to 2 Years
Total number of FLAIR late enhancing lesions as detected by brain MRI at the end of the treatment periodUp to 2 years
