Notes
[1] - The number of subjects starting the period is not consistent with the number completing the preceding period. It is expected the number of subjects starting the subsequent period will be the same as the number completing the preceding period.
Justification: Participants who have completed both the Treatment Period and the Treatment-Free Period will be invited to participate in the OLE. Participants will be re-consented for participation and enter the OLE screening period where they will undergo an evaluation for continued eligibility. Participants who are not eligible, or choose not to enter the OLE will complete the trial after their B-cells have repleted.

Were there any global substantial amendments to the protocol? Yes

11 Jun 2008

The following changes were made as per amendment B: •Collection of persisting gadolinium-enhancing T1 lesions was added. •The transition to Cycle 2 for participants enrolled into Group D was clarified. •An exclusion criterion relating to potential hypersensitivity as a result of human serum albumin contained in the Avonex vials was added. •A risk-benefit reassessment/stopping rule was added. •Consistency was provided in the Expanded Disability Status Scale (EDSS) increase for assessment of disability progression within the protocol. •The difference between treatment withdrawal and study withdrawal was clarified. •The window for study Magnetic Resonance Imaging (MRI) scans was clarified; it was also clarified that the sites would not receive reports from the central MRI reading center. •The requirement of blood samples in order to have baseline values for participants in Group D prior to first Ocrelizumab (OCR) dose was added. •The assessment of protocol-defined relapses was clarified. •A standardized questionnaire for the telephone interview was provided. •The frequency of John Cunningham Virus (JCV) plasma sampling was increased. •Procedures for sample analysis for suspected progressive multifocal leukoencephalopathy (PML) were provided. •An exploratory investigation of patient-reported outcome (PRO) scales for potential implementation in Phase III was added. •Retreatment criteria were provided. •The requirement for clinical evaluations prior to re-dosing with OCR was clarified. •Reporting of clinical relapses and secondary progressive Multiple Sclerosis (MS) as Adverse Events (AEs) was included. •Consistent terminology for the grading of infusion reaction intensity was provided.

15 Oct 2011

The following changes were made as per amendment C: the addition of an Open Label Extension (OLE) period of the study following the Treatment free period (TFP).

03 Apr 2012

The following changes were made as per Amendment D: the window for the Week 144 visit to allow participants the opportunity to enter the OLE following the TFP was increased from 24 weeks to 96 weeks.

22 Dec 2015

The following changes as per amendment E •The duration of OLE period was extended for the participants having completed their 4 years of open-label ocrelizumab treatment. •The permittance of alternative MS treatments and prolongation of the monitoring period for participants switching to other MS therapies post-ocrelizumab was clarified. •Voluntary collection of pregnancy outcomes and infant health information on the first year of life was added. •The telephone interview script was updated to clarify the purpose of the telephone interview. •The activities of the independent Data Monitoring Committee (iDMC) for the OLE period were clarified. •Minor changes and clarifications were made to the schedule of assessments for the OLE period of the study to improve consistency

04 Aug 2016

The following changes were made as per amendment F: •The version of ocrelizumab that would be administered across the program was changed such that each vial contains 300 mg ocrelizumab. Updated guidance on the storage of infusion bags and a requirement on the use of an infusion set with an infusion set with an in-line filter was added. •The safety section was updated to align the safety language with the Investigator’s Brochure, reflecting the outcome from the Phase III clinical studies.

01 Feb 2017

The following change was made as per amendment G: OLE period of the study was extended to provide participants with the opportunity to continue receiving benefit from ocrelizumab treatment based on positive Phase III relapse multiple sclerosis (RMS) data.

27 Sep 2017

The following changes were made as per amendment H: •The protocol safety wording was updated for the following risks associated with ocrelizumab treatment: infusion-related reaction (IRR) risk, infection risk, delayed return of peripheral B cells, decrease in immunoglobulins, malignancy including breast cancer risk, progressive multifocal leukoencephalopathy (PML), including the guidance for PML diagnosis, neutropenia, serious infections related to decrease in immunoglobulins, hypersensitivity reactions, and impaired response to immunization. The following risks associated with ocrelizumab treatment have been removed after the latest benefit–risk assessments: cardiovascular disorders and immunogenicity. •Adverse Events of Special Interest (AESIs) were required to be reported by the Investigator to the Sponsor immediately (i.e., no more than 24 hours after learning of the event). •With antihistamines considered as part of the pretreatment regimen, the risks associated with antihistamine use were added (Warnings and Precautions). •Contraception requirements for male participants and female partner pregnancy reporting were removed. •Contraception requirements, duration of contraception, and procedures for pregnant women during OLE period were updated.

15 Aug 2018

The following changes were made as per amendment I: •The OLE treatment period was extended to 31 December 2020 to provide additional long-term efficacy and safety data. •Language was updated pertaining to impairment of vaccination response. •Retreatment with ocrelizumab for participants with active tuberculosis and for pregnant or breastfeeding female participants was clarified. •Information regarding exposure in utero to ocrelizumab and administration of live or live-attenuated vaccines to neonates and infants were added. •Language related specially to Case Report Forms (CRFs) was deleted to allow for conversion to electronic capture.

09 Feb 2020

The following changes were made as per amendment J: •For the first participant entering OLE period, the maximum duration was modified to 11 years. •The safety risks for ocrelizumab were updated. •The pharmacokinetic/anti-drug antibody (ADA) collection/analysis was removed because immunogenicity incidence with ocrelizumab is very low (<1%) with no safety risks identified, so continuous monitoring in this population is unnecessary. •The plasma and urine sample collection for John Cunningham virus (JCV) was removed because there is no evidence that JCV antibody index (or similar) informs the risk of PML for participants on ocrelizumab. •Guidance for diagnosis of PML was updated. •Guidance for reporting abortions was updated. •Reference to Medical Monitor was changed where applicable and the emergency contact information was updated.

31 Jul 2020

The following change was made as per amendment K: The option of a shorter study drug infusion regimen was added to reduce burden on participants and infusion centers during the OLE period.

The following changes were made as per amendment L: •The benefit-risk assessment for concomitant use of SARS-CoV-2 vaccines was updated. •Language was added to clarify that participants who complete or who discontinue the OLE period treatment early, for any reason, would be followed up for a maximum of 48 weeks after the last infusion of ocrelizumab. Continued B-cell monitoring for participants whose B cells are not repleted (i.e., returned to baseline levels or the lower limit of normal, whichever is lower) was removed because no increased safety risk was identified in the ocrelizumab clinical development program following cessation of treatment. •Language was added to clarify that participants who switch to commercial ocrelizumab after entering B-cell monitoring or enter into treatment with another Disease modifying therapy (DMT) would be discontinued from B-cell monitoring and from the study.

Were there any global interruptions to the trial? No

Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
