A global clinical study in patients with relapsing-remitting multiple sclerosis to investigate the effect of two different dose regimens of ocrelizumab compared to a placebo or Avonex by measuring the effect on brain lesions seen on MRI.

Inclusion Criteria

1. Ability to provide written informed consent and to be compliant with the schedule of protocol assessments; 2. Relapsing-remitting MS, in accordance with the revised McDonald criteria (2005); 3. Ages 18-55 years inclusive; 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 MS disease burden 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 as a minimum (adherence to local requirements, if more stringent, is required): - Two methods of contraception throughout the trial, including the active treatment phase AND for 48 weeks after the last dose of ocrelizumab, or until their B-cells have repleted, whichever is 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). 8. For patients of non reproductive potential (adherence to local requirements, if more stringent, is required): 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 (castration)

Exclusion Criteria

9. Secondary or primary progressive multiple sclerosis at screening (Visit 1); 10. Disease duration of more than 15 years in patients with an EDSS `?¤ 2.0; 11. Incompatibility with MRI (contraindications for MRI include but is not restrictive to known allergy to gadolinium contrast dyes, renal impairment which would contraindicate gadolinium injection, claustrophobia, weight `?¥ 140 kg, pacemaker, cochlear implants, intracranial vascular clips, surgery within 6 weeks of entry into the study, coronary stent implanted within 8 weeks prior to the time of the intended MRI, etc.); 12. Contra-indications to or intolerance of oral or i.v. corticosteroids, including methylprednisolone administered i.v., according to the country label, including: a. Psychosis not yet controlled by a treatment; b. Hypersensitivity to any of the constituents; 13. Known presence of other neurologic disorders, including but not limited to, the following: a. History of ischemic cerebrovascular disorders (e.g. stroke, transient ischemic attack) or ischemia of the spinal cord; b. History or known presence of CNS or spinal cord tumor (e.g. meningioma, glioma); c. History or known presence of potential metabolic causes of myelopathy (e.g. untreated vitamin B12 deficiency); e. History or known presence of infectious causes of myelopathy (e.g. syphilis, Lyme disease, HTLV-1, herpes zoster myelopathy); f. History of genetically inherited progressive CNS degenerative disorder (e.g. hereditary paraparesis; MELAS [mitochondrial myopathy, encephalopathy, lactacidosis, stroke] syndrome); g. Neuromyelitis optica; h. History or known presence of systemic autoimmune disorders potentially causing progressive neurologic disease (e.g., lupus, anti-phospholipid antibody syndrome, Sjogren`s syndrome, Behcet`s disease); i. History or known presence of sarcoidosis; j. History of severe, clinically significant brain or spinal cord trauma (e.g., cerebral contusion, spinal cord compression); k. History of progressive multifocal leukoencephalopathy (PML). .... et al.
