Brief summary:
B-cells have an important role in the pathogenesis of multiple sclerosis (MS). Ocrelizumab, a medication that targets B-cells have been found to be highly effective in stopping the disease activity in relapsing-remitting MS.

The efficacy of ocrelizumab might be related to the specific pattern of B-cell tolerance defect in patients with MS and the potential of its normalization with treatment with ocrelizumab. By analyzing the reactivity of recombinant antibodies expressed from single B-cells, the investigators' collaborators have demonstrated that the pattern of B-cell tolerance defect is different in people with MS who only display an impaired removal of developing autoreactive B-cells in the periphery while central B-cell tolerance in the bone marrow is functional in most patients. In contrast, patients with rheumatoid arthritis (RA), type-1 diabetes (T1D) or Sjögren's syndrome (SS) show defective central and peripheral B-cell tolerance checkpoints. As a consequence, while anti-B-cell therapy does not correct defective early B-cell tolerance checkpoints in T1D and only temporarily slows down autoimmune processes before newly generated autoreactive B-cells likely induce patient relapse, the investigators postulate that the efficacy of ocrelizumab in MS may be linked to normal central B-cell tolerance and the production of a normal B-cell and T-cell compartment after ocrelizumab therapy.

In an open-label study, 10 patients with relapsing MS will be treated with two courses of ocrelizumab and will be followed clinically and radiologically for at least two and a half years. Assessment of T and B-cell phenotypes and function at baseline and 18-24 months post-B-cell depletion will be the primary outcome of the study.

INTRODUCTION 
 
B-cell depleting anti-CD20 monoclonal antibody, ocrelizumab, has been shown to reduce the multiple 
sclerosis (MS) disease activity and using the most objective measure (Gd-enhancing lesions on the MRI), 
it effectively stops the disease. The short-term use of this medication has been safe and aside from 
preventable or manageable infusion reactions, no short-term serious side effects have been associated 
with them. However, it is not clear how depleting the peripheral blood from B-lymphocytes results in 
cessation of the disease activity. Here, we hypothesize that peripheral B-cell depletion corrects the B-cell 
tolerance defect that is seen in the majority of patients with MS.  Defects in early B-cell tolerance 
checkpoints 
are 
associated 
with 
many 
autoimmune diseases including MS, type-1 
diabetes (T1D), rheumatoid arthritis (RA), 
pediatric systemic lupus erythematosus (SLE) 
and systemic sclerosis (SS), and result in large 
numbers of circulating autoreactive B-cells in 
the blood of these patients (Figure 1).  
 
 
 
Early B-cell tolerance checkpoints include a central B-
cell selection step in the bone marrow (BM) that is 
vastly dependent on sensing self-antigen binding to B-
cell receptors (BCRs) and most likely Toll-like receptors (TLR), whereas the peripheral B-cell tolerance 
checkpoint appears to require functional regulatory T cells (Treg) to prevent the accumulation of 
autoreactive mature naïve B-cells. In line with these observations, polymorphisms in PTPN22, BLK, LYN, 
CSK, BANK1 identified by genome-wide association studies (GWAS) as susceptibility genes for RA, SLE, or 
T1D but not MS, encode components regulating BCR signaling and likely result in the impaired central B-
cell tolerance characteristic of T1D, RA, and SLE (Figure 1A) . In contrast, people with MS do not display 
gene polymorphisms linked to the BCR signaling pathway and most of these patients establish normal 
central B-cell tolerance (Figure 1A). However, people with MS suffer from an impaired peripheral B-cell 
tolerance checkpoint, resulting in the accumulation of autoreactive mature naïve B-cells in their blood 
potentially linked to alterations of their Treg function and IFN and IL-17 production (Figure 1B). 
Interestingly, IL-17 production by T cells and T follicular helper (Tfh) development is favored by IL-6, a pro-
Figure 1. Normal central but defective peripheral B-
cell tolerance checkpoint in MS. (A) Central B-cell 
tolerance is functional in most people with MS. The 
frequencies of polyreactive new emigrant/transitional 
B-cells that recently exited the bone marrow are 
elevated in patients with type 1 diabetes (T1D), 
rheumatoid arthritis (RA), pediatric systemic lupus 
erythematosus (SLE) and primary sjögren’s syndrome 
(SS) but low in healthy donors (HD) and most people 
with MS. (B) All patients with autoimmune diseases 
display 
impaired 
peripheral 
B-cell 
tolerance 
checkpoint as illustrated by elevated proportions of 
mature naïve B-cells expressing antibodies that bind 
antigens from HEp-2 cell lysate compared to HD 
controls. The number of patients is indicated and stars 
indicate significant differences with HD (** P<0.01, *** 
P<0.001, **** P<0.0001). 


inflammatory cytokine that is secreted with GM-CSF by B-cells from people with MS. Since anti-B-cell 
therapy normalizes IL-6 production in newly generated B-cells, this regiment may therefore also decrease 
IL-17 production by T cells including Tregs and circulating Tfh in treated people with MS in remission. In 
addition, B-cells have been shown to support the maintenance of memory T cells and their elimination 
may therefore favor the elimination of self-antigen specific T cells secreting inflammatory cytokines.32 
Moreover, transitional B-cells enhanced after anti-B-cell therapy may also secrete increased amount of 
IFN, which has been shown to improve the condition of people with MS. We hypothesize that long-term 
suppression of disease activity in MS is the result of anti-B-cell therapy eliminating autoreactive B-cells in 
patients’ blood and that newly generated B-cells after B-cell repopulation will not contain autoreactive 
clones associated with autoimmunity, an observation that may correlate with a normalized Treg 
compartment that no longer secrete inflammatory cytokines. Hence, two courses of B-cell depletion may 
correct the peripheral B-cell tolerance defect seen in most people with relapsing MS and this 
normalization may be responsible for the long-term suppression of disease activity.

Primary Objectives 
To test if two courses of treatment with a B-cell depleting antibody, ocrelizumab, corrects the B-cell 
tolerance defects in patients with relapsing MS. 
 
STUDY DESIGN 
 
DESCRIPTION OF THE STUDY 
This is an open label, single-arm study of ocrelizumab in people with relapsing MS. Patients who fulfill 
the eligibility criteria will undergo blood draw for collection of peripheral blood mononuclear cells 
(PBMC). Participants will receive two infusions of ocrelizumab (300 mg) two weeks apart and then six 
months later (one infusion of 600 mg of ocrelizumab). Baseline MRI will be obtained 3 months after the 
first course of treatment. Participants will be followed with clinical visits at least twice a year (or more 
frequently, if needed) and brain, cervical and thoracic spine MRI, up to two and a half years after the 
baseline MRI.  
 Schedule of events. Study visits will be conducted at the Johns Hopkins Outpatient Center (JHOC). Aside 
from obtaining informed consent for participation in the study and collecting peripheral blood 
mononuclear cells (PBMCs) and the NeuroQoL, all other procedures are part of the routine clinical and 
standard of care at Johns Hopkins MS Center. The only deviation from the standard of care in this study 
is stopping the ocrelizumab infusions after two courses. Study procedures are depicted in the following

Screening visit: PI or designee will explain the study consent to study participants, and the study visit 
assessments will occur after the study participants sign the consent form. Screening visit procedures 
include review of eligibility criteria, physical exam, EDSS, collecting vitals, and blood draw (for collecting 
PBMCs), and completion of Neuro-QoL adult item banks. Study participants will be enrolled into the 
study after the study physician confirms participants’ eligibility to move forward with the study.  
RATIONALE FOR STUDY DESIGN 
The reason we chose a single arm, open label study, as opposed to a blinded controlled study is because 
the latter does not help with answering our research question. Our research question is if two courses of 
treatment with anti-CD20 antibody, ocrelizumab corrects the B-cell tolerance defect seen in patients 
with relapsing-remitting multiple sclerosis.   
OUTCOME MEASURES 
PRIMARY OUTCOME MEASURE 
 
Assessment of T and B-cell phenotypes and function at baseline and 18-24 months post-B-cell depletion: 
The assessment T and B-cell phenotypes and function and analysis of the central and peripheral B-cell 
tolerance checkpoints, as well as measurement of cytokines will be done at Dr. Hamad’s Lab at Johns 
Hopkins University. 50 milliliters of blood will be drawn from participants before start of the treatment 
with ocrelizumab (at the screening visit) and 12 or 18 months after the second course of ocrelizumab 
infusion (month 18 or 24 of the study) and will be sent to Dr. Hamad’s Lab for the analyses explained 
below.  We will investigate the T and B-cell phenotypes in fresh blood samples from 10 individuals with 
MS pre-treatment and after they repopulate their peripheral B-cells likely at either 18 or 24 months’ 
time points.  We will follow the frequencies of CD3+CD4+CD25hiCD127loFOXP3+ Tregs, circulating 
CD3+CD4+CXCR5+PD-1+ Tfh cells increased in several autoimmune diseases, and other CD4+ and CD8+ 
naïve and memory T cell subpopulations. We will also assess the production of several cytokines 
including IL-10, IL-17, and IFN-gamma by Tregs and other T cell subsets after activating PBMCs with 
phorbol-12-myristate-13-acetate (PMA) and ionomycin for 4 hours in the presence of GolgiStop (BD 


Biosciences) and intracellular staining with specific monoclonal anti-cytokine antibodies as previously 
reported by our laboratory. Hence, we will determine if the abnormal production of IL-17 and IFN 
previously identified in Tregs from people with MS or their elevated Tfh frequencies are corrected after 
two courses of anti-B-cell deletion. In addition, we will assess in vitro the suppressive function of Tregs 
from people with MS before and after B-cell deletion. Indeed, Tregs from people with MS have been 
reported to display decreased suppressive function and we will therefore be able to determine if 
ocrelizumab can normalize Treg function and if this feature is associated with long-term disease 
suppression. 
Because of the lack of lineage-specific markers or transcription factors, IL-10 expression will be used as a 
major readout to determine Bregs. We will use the following two methods: 1) Direct detection of IL-10 
on total PBMCs stimulated with PMA+ionomycin (with Golgi block) for 4-5 hours followed by cell surface 
CD19/CD24/CD38/CD27 (with CD19+CD24hiCD38hiCD27- enriched in Bregs). 2) Detection of IL-10 
produced by B cells after in vitro B cell activation. In brief, 250K CD20+ enriched B cells using magnetic 
beads will be activated for 18-24hours in vitro with 1ug/mL CpG-B and 0.05 ug/mL recombinant CD40L. 
B cells will then be stimulated with PMA+ionomycin (with Golgi block) for 4-5 hours followed by cell 
surface CD19/CD24/CD38/CD10/CD27 (with CD19+CD24hiCD38hiCD10hiCD27- enriched in 
Bregs/transitional B cells) and intracellular staining with anti-IL-10. We may better detect the production 
of IL-10 with this in vitro B cell stimulation protocol. 
We will also characterize various B-cell subpopulations in the blood of people with MS before and after 
treatment with ocrelizumab. We will follow the frequencies of CD19+CD10+CD27-IgMhiCD21lo 
transitional B-cells that recently emigrated from the bone marrow, CD19+CD10-CD27-IgM+CD21+ 
mature naïve B-cells, CD19+CD10-CD27+IgM+CD21+ circulating marginal zone/ IgM memory B-cells, 
CD19+CD10-CD27+IgM-IgG+CD21+ and CD19+CD10-CD27+IgM-IgA+CD21+ conventional IgG+ and IgA+ 
isotype switched B-cells as well as unconventional CD19+CD10-CD27-CD21lo CD11c+ memory B-cells 
that express T-bet, contain autoreactive clones and are generated after TLR activation in the presence of 
IFN-gamma and IL-21. The impact of anti-B-cell therapy on B-cell activation will also be determined by 
following CD69 expression that we previously reported to be increased on B-cells from people with MS. 
The expression of other B-cell activation markers such as CD80, CD86, TACI and FAS will also be assessed 
by flow cytometry on each B-cell subsets described above. We will also obtain a preview on the 
peripheral B-cell selection in MS by characterizing their proliferative homeostasis history by following 
the expression of proliferation marker Ki67 and using the detection of Kappa recombination excision 
circles (KREC) by quantitative PCR in freshly isolated B-cell subpopulations from healthy controls and 
people with MS before and after anti-B-cell deletion as previously described. Indeed, we previously 
reported that mature naïve B-cells from people with MS have undergone increased homeostatic 
expansion in the periphery that may result from the amplification of autoreactive clones. Altogether, 
these studies will determine the impact of anti-B-cell therapy on the phenotype and function of T and B-
cells in people with MS. 
Analysis of the peripheral B-cell tolerance checkpoints in people with MS before and after anti-B-cell 
therapy: We propose to assess the peripheral B-cell tolerance checkpoints in ten people with MS before 
and after treatment with ocrelizumab. Single CD19+CD10hiCD21-/loIgMhiCD27- new 
emigrant/transitional and CD19+CD10-CD21+IgM+CD27- mature naive B-cells will be isolated from the 
blood of these patients before and after treatment and frequencies of polyreactive, HEp-2 reactive and 
anti-nuclear clones will be determined as previously described. In brief, Ig heavy and light chain genes 


will be amplified by RT-PCR and 20-30 immunoglobulin genes from single new emigrant/transitional and 
mature naïve B-cells will be cloned and expressed in vitro. Recombinant antibodies will be tested for 
HEp-2 reactivity and polyreactivity by ELISAs and anti-nuclear reactivity using indirect fluorescence assay 
on HEp-2 slides as previously described.43 Recombinant antibodies will be considered polyreactive 
when they recognized all three antigens tested individually  (dsDNA, insulin, and LPS) using supernatants 
tested at 1μg/ml antibody concentrations and three 1:4 dilutions in PBS as reported. In HEp-2 and 
polyreactivity ELISAs, ED38 recombinant antibody will be used as positive control. Hence, we will 
determine if B-cell depletion can correct the impaired removal of developing autoreactive B-cells in the 
periphery of people with MS and is associated with disease suppression. 
Anticipated results and potential pitfalls: We anticipate that B-cell depletion will correct the altered 
phenotype and function of T and B-cells from people with MS and normalize the production of pro-
inflammatory cytokines in both T and B-cells. In addition, we expect that the majority of people with MS 
before the anti-CD20 treatment, will display a normal central B-cell tolerance with low proportions of 
autoreactive new emigrant/transitional B-cells similar to those in normal controls as previously reported 
(Figure 1A). In contrast, we anticipate that the peripheral B-cell tolerance checkpoint will be defective in 
MS before ocrelizumab treatment as previously reported (Figure 1B). However, we expect that mature 
naïve B-cells after B-cell repopulation 18-24 weeks post initial anti-CD20 treatment will show a pattern 
of antibody autoreactivity similar to normal controls. In other words, a short-course of treatment with 
an anti-CD20 antibody would correct the peripheral B-cell tolerance defect in most people with MS and 
this correction to be associated with long-term absence of disease activity. On the other hand, in the 3-4 
people with MS who may present baseline central B-cell tolerance defect (30% in Kinnunen et al. and 
Figure 1A), the effects of transient B-cell depletion therapy may not be long-lasting. We may further test 
if a two-course treatment may induce long lasting remission through the sustained establishment of 
proper B cell tolerance at least in some MS patients by evaluating again their proportions of 
autoreactive B cells two years later (48 month time point). Although these studies are beyond the time 
frame of this project, the samples collected during the current proposed analysis will allow us to address 
this question. 
Secondary Outcome Measures 
Time to return of disease activity after the third month post-first-infusion, objectively demonstrated by 
development of new T2 hyperintense lesions or Gd-enhancing lesions on the MRI or a clinical relapse 
that is confirmed with an objective change in the neurological examination; proportion of patients who 
experience one step worsening or improvement of EDSS that is confirmed on a clinical visit six months 
later; Neuro-QoL in the computer-adaptive test (CAT) format before the infusions and in all the 
subsequent clinic visits. 
SAFETY PLAN 
Patients will be evaluated at each study visit for the duration of their participation in the study. The 
safety plan is described in detail later in the protocol.  
COMPLIANCE WITH LAWS AND REGULATIONS 
This study will be conducted in accordance with current U.S. Food and Drug Administration (FDA) Good 
Clinical Practices (GCPs), and local ethical and legal requirements. 


MATERIALS AND METHODS 
SUBJECTS 
Subject Selection 
Participants will be recruited at the Johns Hopkins MS Center. We will recruit 10 patients with relapsing 
MS who are naïve to DMTs or have been on injectable DMTs (interferons or glatiramer acetate) or have 
been off of natalizumab, fingolimod or dimethyl fumarate for at least three months and have at least 
one Gd-enhancing lesions on the brain and/or spinal cord MRI on a scan obtained in three months prior 
to enrollment OR have at least one new T2/FLAIR lesion on the brain or spinal cord MRI done in three 
months prior to enrollment (compared to a previous MRI performed within 18 months of the most 
recent MRI).  
We plan to enroll participants who have active disease, as the absence of disease activity in the follow-
up period in these patients would be more meaningful. 
Inclusion and exclusion Criteria 
Inclusion criterion

A negative urine or serum pregnancy test must be 
available for premenopausal women and for women <12 
months after the onset of menopause, unless they have 
undergone surgical sterilization 
Women of childbearing potential must agree to remain 
abstinent (refrain from heterosexual intercourse) or use 
one method of contraception with a failure rate of <1% 
per year or a barrier method supplemented with 
spermicide.  Contraception must continue for the 
duration of study treatment and for at least 24 weeks 
after the last dose of study treatment$$ 


Exclusion criterion
Contraindication to treatment with anti-CD20 antibodies, 
including being seropositive for HBsAg 
Active hepatitis B virus infection
Ever received B-cell depleting antibodies (rituximab, 
ocrelizumab, ofatumumab), alemtuzumab, daclizumab, 
mitoxantrone or hematopoietic stem-cell transplant 
Pregnant or lactating women
Hypersensitivity to ocrelizumab
Treatment with steroids in the past 30 days
$$ A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (≥ 
12 continuous months of amenorrhea with no identified cause of other than menopause), and has not undergone surgical 
sterilization (removal of the ovaries and/or uterus) 
Examples of contraceptive methods with a failure rate of <1% per year include bilateral tube ligation, male sterilization, 
established hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine 
devices. 
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and 
usual lifestyle of the patient.  Periodic abstinence and withdrawal are not acceptable methods of contraception. 
Examples of barrier methods supplemented with the use of spermicide include male or female condom, cap, diaphragm, or 
sponge. 
METHOD OF TREATMENT ASSIGNMENT 
This is an open label, single arm, unblinded interventional study. All participants will receive similar 
treatment and intervention. 
STUDY INTERVENTIONS 
The intervention in this study is the two courses of infusions of ocrelizumab, an FDA approved 
medication for relapsing MS. The patients will receive ocrelizumab 300 mg IV infusion on days one and 
15, according to the standard infusion protocols. The protocols include pre-medicating with 
acetaminophen 650 mg orally, diphenhydramine 50 mg orally and methylprednisolone 125 mg IV. The 
anti-CD20 antibody infusion will be repeated in six months (single infusion of ocrelizumab 600 mg). 
These infusions are standard of care and are done according to the medication label. However, the 
infusions will not be repeated after these two courses of infusion (the first two infusion of 300 mg 
ocrelizumab two weeks apart is considered one course and the infusion of 600 mg of ocrelizumab six 
months later is considered the second course). 
STUDY ASSESSMENTS 
Signed, IRB approved informed consent will be obtained from patients prior to the pretreatment 
assessments.  We will ensure that informed consent will be obtained for any mandated testing or 
screening process for this protocol. 


Screening visit: PI or designee will explain the study consent to study participants, and the study visit 
assessments will occur after the study participants sign the consent form. Screening visit procedures 
include review of eligibility criteria, physical exam, neurological examination, collecting vitals, blood 
work for assessing eligibility (liver function tests, complete blood count, Hepatitis- B surface antigen, 
Hepatitis-B core antibody, HIV antibody, lymphocyte subset including CD19+ B-cells, total IgG and IgM 
and urine pregnancy test) and blood draw (for collecting PBMCs), and completion of Neuro-QoL adult 
item banks. Study participants will be enrolled into the study after the study physician confirms 
participants’ eligibility to move forward with the study.  
 
Obtaining the B-cell depleting antibody (ocrelizumab) and all the subsequent study visits and MRIs are 
part of routine and standard clinical care. If the B-cell depleting medication is not approved by the 
participants’ insurance policy, the patient will be excluded from the  
MRI procedures: MRI scans will be performed as part of the standard of care. Conventional 
T2/FLAIR/T1-weighted images as well as post-contrast T1-weighted images of the brain will be obtained 
at months 3 (baseline), 12, 18, 24 and 30. Conventional T2/STIR/T1-weighted images as well as post-
contrast T1-weighted images of the cervical and thoracic spinal cord will be obtained at months 3 
(baseline), 12 and 24. Similar to the standard of care, brain, cervical or thoracic spine MRIs may be done 
as needed if the patient develop symptoms that could be suggestive for an MS relapse (based on the 
evaluation by a study neurologist). The MRI scans will be read by an attending radiologist at Johns 
Hopkins University, and these readings will be used for making decisions regarding the presence of new 
T2 or Gd-enhancing lesions suggestive for re-emergence of the radiological disease activity.   
Assessments during Treatment

Changes in the study visits and procedures in to response to the CIVD-19 pandemic: 
Considering the recent events surrounding the COVID-19 pandemic and JHU response, and the fact that 


our study participants can be theoretically vulnerable to the infection with the novel coronavirus, we will 
implement the following changes in our study protocol to reduce  the immediate hazard to our 
participants related to the risk of exposure to COVID-19: 
- 
Follow-up visits, including Month 3, Month 6, Month 12 Month 18, Month 24 and Month 30 in-
person visits can be replaced with telemedicine visits with the study PI.  
- 
The medical history, symptom evaluation and side effects assessment components of the study 
visits will be conducted through the telemedicine visits.  
- 
The physical examination, vital signs assessment, neurological examination, OCT and research 
blood sample collection for future analysis will be paused temporarily, as they would require an 
in-person visit and would pose a risk to the participants and the staff. They will be resumed as 
soon as possible, after the resumption of normal research activities at the JHU. 
- 
The NeuroQoL quality of life assessment will be delivered to particpants electronically. Secure 
Redcap surveys will be sent to the participants’ email address. Results will be printed and filed in 
the study binders as usual. 
- 
The blood work to assess and monitor safety and adverse effects of the therapy, including 
lymphocyte subset analysis, will continue to be ordered and results will be reviewed electronically 
by the PI. 
- 
Infusions of ocrelizumab: Delaying the ocrelizumab infusions will be determined on a case-by-case 
basis by the PI. 
- 
MRI Procedures: MRI studies may be delayed because of the delays in the ocrelizumab infusions.  
 
DISCONTINUATION OF PROTOCOL-SPECIFIED THERAPY 
Protocol-specified therapy may be discontinued for any of the following reasons: 
• 
Unacceptable toxicity 
• 
Patient election to discontinue therapy (for any reason) 
• 
Physician’s judgment 
SUBJECT DISCONTINUATION 
Treatment stop rules: Stopping the study is equivalent to restarting the B-cell depleting antibody (i.e. 
ocrelizumab) or another DMT, if there is medical contraindication to the continued use of ocrelizumab 
(e.g. development of allergic or severe infusion reactions during the last infusion). The followings are the 
criteria for restarting the DMT (stopping the study).  
1. A clinical relapse, affecting optic nerves (with worst visual acuity of 20/50 or less) or causing motor 
weakness, ataxia, bladder or bowel symptoms. Pseudo-relapses are not uncommon among patients with 
MS. When in doubt, the PI will use MRI to confirm development of new lesions corresponding to 
patient’s symptoms (based on the possible localization of the symptoms).   
2. Development of two new T2 hyperintense lesions or two gadolinium enhancing lesions on any MRI 
after the baseline MRI. The baseline MRI was defined the MRI that is obtained after three months 
subsequent to the first ocrelizumab infusion.   


Termination rule 
 If four patients during the study required retreatment with ocrelizumab (or another DMT), we will 
terminate the study (i.e. will offer all participants the choice to resume their DMT).   
STUDY DISCONTINUATION 
Genentech Study Center, and the Principal Investigator has the right to terminate this study at any time.  
Reasons for terminating the study may include the following: 
• 
The incidence or severity of adverse events in this or other studies indicates a potential health 
hazard to subjects 
• 
Subject enrollment is unsatisfactory 
• 
Data recording are inaccurate or incomplete 
• 
Study protocol not followed 
 
STATISTICAL METHODS 
We will describe the demographic, clinical characteristics and MRI data of all participants before 
treatment with the B-cell depleting agent. Using paired t-tests, we will compare the frequency of 
autoreactive mature naïve B-cells, Treg and Tfh cells and cytokine production before treatment with 
ocrelizumab and after the B-cell repopulation. We will report the proportion of participants who 
experience the return of the disease activity and the time to failure event, using a Kaplan-Meyer curve. 
Proportion of patients with clinical relapse, new MRI activity or disability progression will separately be 
reported. Quality of life data will be analyzed using linear mixed effect models.  
To look at the association between long-term response to B-cell depletion therapy and autoreactivity of 
B-cells at different stages of development, we will use logistic regression and Cox proportional hazards 
models with failure or time-to-failure event as the outcome variable and the above-mentioned 
proportion of auto-reactive B-cells at different stages of development and the change in proportions 
before and after treatment as the predictor variables. Failure event as defined by the return of disease 
activity after the third month post-first-infusion, objectively demonstrated by development of new T2 
hyperintense lesions or Gd-enhancing lesions on the MRI or a clinical relapse that is confirmed with an 
objective change in the neurological examination or a corresponding new or enhancing lesion on the 
MRI that is obtained after the onset of symptoms. 
Missing Data 
Because of the small sample size and close follow-up, we do not expect to encounter missing data 
problem. Also, each participant will be his/her own control and no between-patient comparison will be 
made. 
Determination of Sample Size 
Patients’ numbers are also based on our previous studies of central and peripheral B-cell checkpoints in 
patients with autoimmune diseases and healthy control subjects in which we had found that the 
frequency of autoreactive mature naïve B-cells was 48.9±3.06% in patients and 20.1±0.9% in healthy 
donors. Assuming that the frequency of autoreactive cells among post-treatment repopulated B-cells 
will be similar to normal controls, our proposed sample size of 10 subjects per group before and after 


treatment would give us more than 90% power to detect a significant difference with an α of 0.05 with a 
2-sided Student’s t-test. The analysis of each individual is very labor intensive and costly but fortunately, 
significant findings on the establishment of B-cell tolerance can be obtained with a relatively small 
number of subjects. 
Data Management 
We will use Johns Hopkins REDCap (Research Electronic Data Capture) [https://projectredcap.org/], a 
secure web application to collect data, create the study database and access the data for analysis. Study 
coordinator will enter the data required by the protocol into the Electronic Case Report Forms (CRFs). 
The PI will assure that the data entered into CRFs are complete and accurate.       
Data Quality Assurance 
Accurate, consistent, and reliable data will be ensured through the use of standard practices and 
procedures. 
  
SAFETY REPORTING OF ADVERSE EVENTS 
ASSESSMENT OF SAFETY 
 
Specification of Safety Variables 
 
Safety assessments will consist of monitoring and reporting adverse events (AEs) and serious adverse 
events (SAEs) per protocol. This includes all events of death, and any study specific issue of concern. 
Adverse Events 
An AE is any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or 
disease temporally associated with the use of an investigational medicinal product (IMP) or other 
protocol-imposed intervention, regardless of attribution. 
 
This includes the following: 
•  
AEs not previously observed in the subject that emerge during the protocol-specified AE 
reporting period, including signs or symptoms associated with multiple sclerosis that were not present 
prior to the AE reporting period. 
•  
Complications that occur as a result of protocol-mandated interventions (e.g., invasive 
procedures such as cardiac catheterizations) 
•  
If applicable, AEs that occur prior to assignment of study treatment associated with medication 
washout, no treatment run-in, or other protocol-mandated intervention. 
•  
Preexisting medical conditions (other than the condition being studied) judged by the 
investigator to have worsened in severity or frequency or changed in character during the protocol-
specified AE reporting period. 


 
Serious Adverse Events 
 
An AE should be classified as an SAE if the following criteria are met: 
•  
It results in death (i.e., the AE actually causes or leads to death). 
•  
It is life threatening (i.e., the AE, in the view of the investigator, places the subject at immediate 
risk of death. It does not include an AE that, had it occurred in a more severe form, might have caused 
death.). 
•  
It requires or prolongs inpatient hospitalization. 
•  
It results in persistent or significant disability/incapacity (i.e., the AE results in substantial 
disruption of the subject’s ability to conduct normal life functions). 
•  
It results in a congenital anomaly/birth defect in a neonate/infant born to a mother exposed to 
the IMP. 
•  
It is considered a significant medical event by the investigator based on medical judgment (e.g., 
may jeopardize the subject or may require medical/surgical intervention to prevent one of the outcomes 
listed above). 
METHODS AND TIMING FOR ASSESSING AND RECORDING SAFETY VARIABLES 
The investigator is responsible for ensuring that all AEs and SAEs that are observed or reported during 
the study are collected and reported to appropriate IRB(s), and Genentech, Inc. 
Adverse Event Reporting Period 
The study period during which AEs and SAEs as described in section J where the patient has been 
exposed to Genentech product must be reported. Reporting period begins after informed consent is 
obtained and initiation of study treatment and ends 30 days following the last administration of study 
treatment or study discontinuation/termination, whichever is earlier. After this period, investigators 
should only report SAEs that are attributed to prior study treatment. 
Assessment of Adverse Events 
 
All AEs and SAEs whether volunteered by the subject, discovered by study personnel during questioning, 
or detected through physical examination, laboratory test, or other means will be reported 
appropriately. Each reported AE or SAE will be described by its duration (i.e., start and end dates), 
regulatory seriousness criteria if applicable, suspected relationship to the ocrelizumab (see following 
guidance), and actions taken. 
To ensure consistency of AE and SAE causality assessments, investigators should apply the following 
general guideline: 
Yes 


There is a plausible temporal relationship between the onset of the AE and administration of the {study 
drug}, and the AE cannot be readily explained by the subject’s clinical state, intercurrent illness, or 
concomitant therapies; and/or the AE follows a known pattern of response to the ocrelizumab or with 
similar treatments; and/or the AE abates or resolves upon discontinuation of the ocrelizumab or dose 
reduction and, if applicable, reappears upon re- challenge. 
No 
Evidence exists that the AE has an etiology other than the ocrelizumab (e.g., preexisting medical 
condition, underlying disease, intercurrent illness, or concomitant medication); and/or the AE has no 
plausible temporal relationship to ocrelizumab administration (e.g., cancer diagnosed 2 days after first 
dose of study drug). 
Expected adverse events are those adverse events that are listed or characterized in the Package Insert 
(P.I) or current Investigator Brochure (I.B). 
Unexpected adverse events are those not listed in the P.I or current I.B or not identified. This includes 
adverse events for which the specificity or severity is not consistent with the description in the P.I. or I.B. 
For example, under this definition, hepatic necrosis would be unexpected if the P.I. or I.B. only referred 
to elevated hepatic enzymes or hepatitis. 
PROCEDURES FOR ELICITING, RECORDING, AND REPORTING ADVERSE EVENTS 
Eliciting Adverse Events 
A consistent methodology for eliciting AEs at all subject evaluation time points should be adopted. 
Examples of non-directive questions include: 
•  
“How have you felt since your last clinical visit?” 
•  
“Have you had any new or changed health problems since you were last here?” 
Specific Instructions for Recording Adverse Events 
Investigators should use correct medical terminology/concepts when reporting AEs or SAEs. Avoid 
colloquialisms and abbreviations. 
a.   Diagnosis vs. Signs and Symptoms 
 
If known at the time of reporting, a diagnosis should be reported rather than individual signs and 
symptoms (e.g., record only liver failure or hepatitis rather than jaundice, asterixis, and elevated 
transaminases). However, if a constellation of signs and/or symptoms cannot be medically characterized 
as a single diagnosis or syndrome at the time of reporting, it is acceptable to report the information that 
is currently available. If a diagnosis is subsequently established, it should be reported as follow-up 
information. 
 
b.   Deaths 
 


All deaths that occur during the protocol-specified AE reporting period (see Section I), regardless of 
attribution, will be reported to the appropriate parties. When recording a death, the event or condition 
that caused or contributed to the fatal outcome should be reported as the single medical concept. If the 
cause of death is unknown and cannot be ascertained at the time of reporting, report “Unexplained 
Death”. 
 
c.   Preexisting Medical Conditions 
 
A preexisting medical condition is one that is present at the start of the study. Such conditions should be 
reported as medical and surgical history. A preexisting medical condition should be re-assessed 
throughout the trial and reported as an AE or SAE only if the frequency, severity, or character of the 
condition worsens during the study. When reporting such events, it is important to convey the concept 
that the preexisting condition has changed by including applicable descriptors (e.g., “more frequent 
headaches”). 
 
d.   Hospitalizations for Medical or Surgical Procedures 
 
Any AE that results in hospitalization or prolonged hospitalization should be documented and reported as 
an SAE. If a subject is hospitalized to undergo a medical or surgical procedure as a result of an AE, the 
event responsible for the procedure, not the procedure itself, should be reported as the SAE. For example, 
if a subject is hospitalized to undergo coronary bypass surgery, record the heart condition that 
necessitated the bypass as the SAE. 
 
Hospitalizations for the following reasons do not require reporting: 
•  
Hospitalization or prolonged hospitalization for diagnostic or elective surgical procedures for 
preexisting conditions 
•  
Hospitalization or prolonged hospitalization required to allow efficacy measurement for the study 
or 
•  
Hospitalization or prolonged hospitalization for scheduled therapy of the target disease of the 
study 
 
e.   Assessment of Severity of Adverse Events 
 
 
  
The adverse event severity grading scale for the NCI CTCAE (v5.0 Update current versions) will be used for 
assessing adverse event severity. Below Table should be used for assessing severity for adverse events 
that are not specifically listed in the NCI CTCAE. 


Adverse Event Severity Grading Scale for Events Not Specifically Listed in NCI CTCAE 
Grade 
Severity 
1 
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations 
only; or intervention not indicated 
2 
Moderate; minimal, local, or non-invasive intervention indicated; or limiting 
age-appropriate instrumental activities of daily living a 
3 
Severe or medically significant, but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; or 
limiting self-care activities of daily living b,c 
4 
Life-threatening consequences or urgent intervention indicated d 
5 
Death related to adverse event d 
NCI CTCAE  National Cancer Institute Common Terminology Criteria for Adverse Events. 
Note:  Based on the most recent version of NCI CTCAE (v5.0), which can be found at:  
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm 
a. 
Instrumental activities of daily living refer to preparing meals, shopping for groceries or clothes, using the telephone, 
managing money, etc. 
b. 
Examples of self-care activities of daily living include bathing, dressing and undressing, feeding oneself, using the toilet, 
and taking medications, as performed by patients who are not bedridden. 
c. 
If an event is assessed as a "significant medical event," it must be reported as a serious adverse event  
d. 
Grade 4 and 5 events must be reported as serious adverse events  
 
f. 
  Pregnancy 
If a female subject becomes pregnant while receiving the study drug or within 6 months after the last dose 
of study drug, or if the female partner of a male study subject becomes pregnant while the study subject 
is receiving the study drug or within 6 months after the last dose of study drug, a report should be 
completed and expeditiously submitted to Genentech, Inc. Follow-up to obtain the outcome of the 
pregnancy should also occur. Abortion, whether accidental, therapeutic, or spontaneous, should always 
be classified as serious, and expeditiously reported as an SAE. Similarly, any congenital anomaly/birth 
defect in a child born to a female subject exposed to the study drug should be reported as an SAE. 
 
Additional information on any ocrelizumab-exposed pregnancy and infant will be requested by 
Genentech/Roche Drug Safety at specific time points (i.e. after having received the initial report, at the 
end of the second trimester, 2 weeks after the expected date of delivery, and at 3, 6, and 12 months of 
the infant’s life). 
g. 
Post-Study Adverse Events  
The investigator should expeditiously report any SAE occurring after a subject has completed or 
discontinued study participation if attributed to prior ocrelizumab exposure. If the investigator should 
become aware of the development of cancer or a congenital anomaly in a subsequently conceived 
offspring of a female subject who participated in the study, this should be reported as an SAE adequately 
to Genentech drug Safety during follow up period 


h.  Case Transmission Verification of Single Case Reports 
The Sponsor agrees to conduct  the Case Transmission verification to ensure that all single case reports 
have been adequately received by Genentech  via the sponsor emailing Genentech a Quarterly line-listing 
documenting single case reports sent by the sponsor to Genentech in the preceding time period.  
The periodic line-listing will be exchanged within seven (7) calendar days of the end of the agreed time 
period. Confirmation of receipt should be received within the time period mutually agreed upon. 
             
If discrepancies are identified, the Sponsor and Genentech will cooperate in resolving the discrepancies. 
The responsible individuals for each party shall handle the matter on a case-by-case basis until satisfactory 
resolution.  The sponsor shall receive reconciliation guidance documents within the ‘Activation Package’. 
Following Case Transmission Verification, single case reports which have not been received by Genentech 
shall be forwarded by the sponsor to Genentech within five (5) calendar days from request by Genentech. 
At the end of the study, a final cumulative Case Transmission Verification report will be sent to Genentech 
i.   AEs of Special Interest (AESIs) 
AESIs are a subset of Events to Monitor (EtMs) of scientific and medical concern specific to the product, 
for which ongoing monitoring and rapid communication by the Investigator to the Sponsor is required. 
Such an event might require further investigation in order to characterize and understand it. Depending 
on the nature of the event, rapid communication by the trial Sponsor to other parties (e.g., Regulatory 
Authorities) may also be warranted. 
Adverse events of special interest for this study include the following: 
• 
Cases of potential drug-induced liver injury that include an elevated ALT or AST in combination 
with either an elevated bilirubin or clinical jaundice, as defined by Hy’s law: 
o 
Treatment-emergent ALT or AST  3  ULN in combination with total bilirubin  2  ULN 
o 
Treatment-emergent ALT or AST  3  ULN in combination with clinical jaundice 
• 
Data related to a suspected transmission of an infectious agent by the study drug, as defined 
below: 
o Any organism, virus, or infectious particle (e.g., prion protein transmitting transmissible 
spongiform encephalopathy), pathogenic or non-pathogenic, is considered an infectious agent.  A 
transmission of an infectious agent may be suspected from clinical symptoms or laboratory 
findings that indicate an infection in a patient exposed to a medicinal product.  This term applies 
only when a contamination of the study drug is suspected. 
 
j. Exchange OF SINGLE CASE REPORTS  
The sponsor will be responsible for collecting all protocol-defined Adverse Events (AEs)/Serious Adverse 
Events (SAEs), AEs of Special Interest (AESIs), Special Situation Reports (including pregnancy reports) and 
Product Complaints (with or without an AE) originating from the Study for the Product.  


Investigators must report all the above mentioned single case reports adequately to Genentech within 
the timelines described below. The completed MedWatch or CIOMS I form or Genentech approved 
reporting forms should be faxed/emailed immediately upon completion to Genentech at the following 
contacts: 
All protocol-defined AEs, SAEs, AESIs, Special Situation Reports (including pregnancy reports) and Product 
Complaints with an AE should be sent to: 
Fax: 650-238-6067 
Email: usds_aereporting-d@gene.com 
All Product Complaints without an AE should be sent to: 
Email: kaiseraugst.global_impcomplaint_management@roche.com 
 
It is understood and agreed that the Sponsor will be responsible for the evaluation of AEs/SAEs, AESIs, 
Special Situation Reports (including pregnancy reports) and Product Complaints (with or without an AE) 
originating from the study.  
These single case reports will be exchanged between the parties as outlined below so that regulatory 
obligations are met. 
 
Serious adverse events (SAEs), pregnancy reports (including pregnancy occurring in the partner of a male 
study subject) AEs of special interest (AESIs) and Special Situation Reports, where the patient has been 
exposed to the Genentech Product, will be sent on a MedWatch form or CIOMS I form or on Genentech 
approved reporting forms to  Genentech Drug Safety. Transmission of these reports (initial and follow-up) 
will be either electronically or by fax and within the timelines specified below: 
•

errors) or occupational exposure, with or without association with an AE/SAE unless otherwise specified 
in the protocol 
•  
Lack of therapeutic efficacy 
•  
Drug interaction 
•  
Use of a Medicinal Product in a Pediatric and Elderly population (in addition, reasonable attempts 
should be made to obtain and submit the age or age group of the patient, in order to be able to identify 
potential safety signals specific to a particular population) 
• 
Product Complaints  
 
All Product Complaints (with or without an AE) shall be forwarded to Genentech within fifteen 
(15) calendar days of the awareness date.

requires Responsible Parties to register and submit summary results of clinical trials with ClinicalTrials.gov. 
The law applies to certain clinical trials of drugs (including biological products) and medical devices. (refer 
to FDAAA 801 Requirements to learn about Responsible Party, Applicable Clinical Trials, and deadlines for 
registration and results submission) 
 
RETENTION OF RECORDS 
U.S. FDA regulations (21 CFR §312.62[c]) require that records and documents pertaining to the conduct 
of this study and the distribution of investigational drug, including CRFs, consent forms, laboratory test 


results, and medication inventory records, must be retained by the Principal Investigator for 2 years after 
marketing application approval.  If no application is filed, these records must be kept 2 years after the 
investigation is discontinued and the U.S. FDA and the applicable national and local health authorities are 
notified.  Genentech will notify the Principal Investigator of these events. 
For studies conducted outside the United States under a U.S. IND, the Principal Investigator must comply 
with U.S. FDA IND regulations and with the record retention policies of the relevant national and local 
health authorities.
