Inclusion Criteria

1. Ability to provide written informed consent and to be compliant with the schedule of protocol assessments;
2. RRMS, in accordance with the revised McDonald criteria (2005);
3. Ages 18-55 years,
4. At least two documented relapses within the last 3 years prior to screening, at least one of which occurred within the last year prior to screening;
5. EDSS at baseline from 1.0 to 6.0 points;
6. Evidence of recent MS activity as defined below:
a. At least six T2 lesions on an MRI scan done in the year prior to screening, based on local reading. Should an MRI scan be unavailable within the last year or showing less than six T2 lesions, a screening MRI scan with at least six T2 lesions is required for the patient to be eligible, or
b. Patient had 2 documented relapses within the year prior to screening;
7. For sexually active female and male patients of reproductive potential, use of reliable means of contraception as described below:
- Two methods of contraception throughout the trial, including the active treatment phase AND, for females, for 24 weeks after the last dose of ocrelizumab, or until their B-cells have repleted, whichever is the longer.
- Acceptable methods of contraception include one primary (e.g. systemic hormonal contraception or tubal ligation of the female partner, vasectomy of the male partner) AND one secondary barrier method (e.g. latex condoms, spermicide) OR a double barrier method (e.g. latex condom, intrauterine device, vaginal ring or pessary plus spermicide (e.g. foam, vaginal suppository, gel, cream)) may be used.
8. For patients of non reproductive potential:
a. Women may be enrolled if postmenopausal (i.e. spontaneous amenorrhea for the past year confirmed by an FSH level greater than 40 mIU/mL unless the patient is receiving a hormonal therapy for their menopause or surgically sterile (i.e. hysterectomy, complete bilateral oophorectomy);
b. Men may be enrolled if they are surgically sterile.

7. History or known presence of recurrent or chronic infection (e.g., hepatitis B or C, HIV, syphilis, tuberculosis)
8. History of cancer, including solid tumors and hematological malignancies (except basal cell, in situ squamous cell carcinomas of the skin, and in situ carcinoma of the cervix of the uterus that have been excised and resolved)
9. History of alcohol or drug abuse within 24 weeks prior to randomization
10. History of or currently active primary or secondary immunodeficiency
11. History or laboratory evidence of coagulation disorders

Exclusions Related to Medications
