    Primary Outcome Measures

    Number of Participants With Any Adverse Event
    An Adverse Event (AE) is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. A list of all adverse events is reported in the "Other (Non-Serious) Adverse Events" section. Non-serious AEs were not collected during the Individualized Follow-up Period.
    Number of Participants With the Indicated Critical Adverse Events (CAEs)
    A CAE=treatment-related (TR) grade (G) >=3 AE on day of infusion (inf.) preventing inf. to be resumed, a TR G 3 bronchospasm during 1 inf., an AE whose severity becomes G 3 for the third time during 1 inf., infections reported as serious, a TR neurological event consistent with progressive multifocal leukoencephalopathy (PML), any malignancy, and any fatal adverse drug reaction. AE severity (assessed as G 1-5) was classified using the Common Terminology Criteria for Adverse Events v3.0: G 1=mild AE; G 2=moderate AE; G 3=severe AE; G 4=life-threatening or disabling AE; G 5=death related to AE.
    Number of Participants With Negative or Unconfirmed Human Anti-human Antibodies (HAHA) in Which Concentrations of Ofa Were Below 500 Nanograms Per Milliliter (ng/ml)
    Participants are checked for negative (or a lack of) HAHA at Baseline, and then throughout the study, to ensure that the investigational product is not causing HAHA development. Participants with concentrations of Ofa that are missing or are above 500 nanograms per milliliter (ng/mL) are considered to have unconfirmed HAHA results.
    Number of Participants With Abnormal Physical Examination Findings
    The investigator performed the physical examination, which included but was not limited to: general appearance and the following body systems: lymph nodes, mouth and throat, lungs, cardiovascular, abdomen, extremities, muscular-skeletal, neurological (apart from multiple sclerosis [a brain and spinal cord disease]), and skin. All abnormal clinically relevant findings such as vein problems (venous varices), disorder of the vertebral column (vertebropathy), increased hearing loss, post operative mark (scar), and chronic skin disorder with no sweat and itching (anhidrotic eczema) were reported.
    Change From Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in Basophils, Eosinophils, Leukocytes, Monocytes, Lymphocytes, Neutrophils, and Platelet Count at Week 24 (FTP), Week 48 (STP), and Week 104 (IFUP)
    Blood samples of participants were collected for hematology assessment. Change from Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in basophils, eosinophils, leukocytes, monocytes, lymphocytes, neutrophils, and platelets count was calculated as the value at Visit 10 (Week 24) for the FTP, the value at Visit 17 (Week 48) for the STP, and the value at Week 104 for the IFUP minus the value at Baseline.
    Change From Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in Erythrocyte Count at Week 24 (FTP), Week 48 (STP), and Week 104 (IFUP)
    Blood samples of participants were collected for assessment of erythrocyte count. Change from Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in erythrocyte count was calculated as the value at Visit 10 (Week 24) for the FTP, the value at Visit 17 (Week 48) for the STP, and the value at Visit 26 (Week 104) for the IFUP minus the value at Baseline.
    Change From Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in Hematocrit at Week 24 (FTP), Week 48 (STP), and Week 104 (IFUP)
    Blood samples of participants were collected for hematocrit assessment. Hematocrit is the percentage of blood volume (BV) that is occupied by red blood cells (RBCs). Change from Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in hematocrit was calculated as the value at Visit 10 (Week 24) for the FTP, the value at Visit 17 (Week 48) for the STP, and the value at Visit 26 (Week 104) for the IFUP minus the value at Baseline. Hematocrit is measured as a percentage, i.e., volume (V) of red blood cells per volume of blood.
    Change From Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in Hemoglobin Count at Week 24 (FTP), Week 48 (STP), and Week 104 (IFUP)
    Blood samples of participants were collected for assessment of hemoglobin count. Change from Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in hemoglobin was calculated as the value at Visit 10 (Week 24) for the FTP, the value at Visit 17 (Week 48) for the STP, and the value at Visit 26 (Week 104) for the IFUP minus the value at Baseline.

    Blood samples of participants were collected for the assessment of bicarbonate, glucose, potassium, and urea. Change from Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) was calculated as the value at Visit 10 (Week 24) for the FTP, the value at Visit 17 (Week 48) for the STP, and the value at Visit 26 (Week 104) for the IFUP minus the value at Baseline.
    Change From Baseline (Week 0 for the FTP,Week 24 for the STP, and Week 0 for the IFUP) in Bilirubin and Creatinine at Week 24 (FTP), Week 48 (STP), and Week 104 (IFUP)
    Blood samples of participants were collected for the assessment of bilirubin and creatinine. Change from Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) was calculated as the value at Visit 10 (Week 24) for the FTP, the value at Visit 17 (Week 48) for the STP, and the value at Visit 26 (Week 104) for the IFUP minus the value at Baseline.
    Change From Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) in Immunoglobins at Week 24 (FTP), Week 48 (STP), and Week 104 (IFUP)
    Blood samples of participants were collected for the assessment of antibodies produced by B-cells (immunoglobins): immunoglobulin A, immunoglobin G, and immunoglobin M. Change from Baseline (Week 0 for the FTP, Week 24 for the STP, and Week 0 for the IFUP) was calculated as the value at Visit 10 (Week 24) for the FTP, the value at Visit 17 (Week 48) for the STP, and the value at Visit 26 (Week 104) for the IFUP minus the value at Baseline.
    Change From Baseline (Week 0 for the FTP and Week 24 for the STP) in Blood Pressure (BP) at Week 24 (FTP) and Week 48 (STP)
    Maximum (systolic) and minimum (diastolic) BP were assessed prior to infusion. Change from Baseline (Week 0 for the FTP and Week 24 for the STP) was calculated as the value at Visit 10 (Week 24) for the FTP and the value at Visit 17 (Week 48) for the STP minus the value at Baseline.
    Change From Baseline (Week 0 for the FTP and Week 24 for the STP) in Pulse Rate at Week 24 (FTP) and Week 48 (STP)
    The pulse rate of each participant was assessed prior to infusion. Change from Baseline (Week 0 for the FTP and Week 24 for the STP) was calculated as the value at Visit 10 (Week 24) for the FTP and the value at Visit 17 (Week 48) for the STP minus the value at Baseline.
    Change From Baseline (Week 0 for the FTP and Week 24 for the STP) in Temperature at Week 24 (FTP) and Week 48 (STP)
    The temperature of each participant was assessed prior to infusion. Change from Baseline (Week 0 for the FTP and Week 24 for the STP) was calculated as the value at Visit 10 (Week 24) for the FTP and the value at Visit 17 (Week 48) for the STP minus the value at Baseline.
    Change From Baseline (Week 0 for the FTP and Week 24 for the STP) in Complement Activation (CH50) at Week 24 (FTP) and Week 48 (STP)
    Blood samples of participants were collected for CH50 prior to and 2 hours after dosing, and the samples were sent to a Central Laboratory for analysis: Bio Analytical Research Corporation (BARC). Change from Baseline (Week 0 for the FTP; Week 24 for the STP) was calculated as the value at Weeks 24 (FTP) and 48 (STP) minus the value at Baseline. Ofa depletes (induces the cell death of) B cells. When Ofa binds to a B cell, it induces complement CH50, which in turn causes cell death via cytotoxicity. Therefore, the CH50 levels were measured to ensure that CH50 was being appropriately activated.

    Secondary Outcome Measures

    Number of the Indicated Types of Lesions (Ls) Assessed Per Magnetic Resonance Imaging (MRI)
    The MRI scan was performed prior to dosing and could be performed up to 4 days prior to Visits 3 and 10. An IDMC reviewed the data. T1 enhancing Ls are enhanced by gadolinium, are considered representative of disease activity/inflammation, and may signify a relapse. Measurement of these Ls is comparative from visit to visit. "Total T1 enhancing Ls" represent the total of the new T1 enhancing Ls over the entire study period. T2 L measurements measure all Ls on the brain in terms of volume and size, measuring for new or enlarging Ls. T1 hypointensive Ls are areas of permanent damage.
    Total Volume of T2 Lesions at Week 24 and Week 48
    The MRI scan should be performed prior to dosing and can be performed up to 4 days prior to Visits 3 and 10. An IDMC reviewed the data. The volume of T2 lesions was not a cumulative volume, but the volume measured at Visit 10 and Visit 17. T2 lesion measurements measure all lesions on the brain in terms of volume and size, measuring for new lesions or enlarging lesions.
    Ofa Drug Concentration After the First (Visit 3), Second (Visit 4), Third (Visit 10), and Fourth (Visit 11) Intravenous (i.v.) Infusions
    The peripheral blood for each participant was collected and analyzed for the concentration of the drug in serum. There were four infusions in the study; the third infusion at Visit 10 represents the first infusion of the second treatment period (Weeks 24-48). Data are presented for the predose concentrations.
    The Maximum Observed Plasma Concentration (Cmax) After the First (Visit 3), Second (Visit 4), Third (Visit 10), and Fourth (Visit 11) i.v. Infusions
    The peripheral blood for each participant was collected and analyzed for Cmax after the first, second, third, and fourth i.v. infusions. Assessment was performed using the noncompartmental method (this analysis is highly dependent on the estimation of total drug exposure).
    The Area Under the Plasma Concentration-time Curve From Time Zero to the Last Quantifiable Time Point (AUC(0-t)) After the First (Visit 3), Second (Visit 4), Third (Visit 10), and Fourth (Visit 11) i.v. Infusions
    The peripheral blood for each participant was collected and analyzed to estimate the area under the plasma concetration-time curve, AUC(0-t), and was assessed using the non-compartmental method.
    Time to Reach Cmax (Tmax) After the First (Visit 3), Second (Visit 4), Third (Visit 10), and Fourth (Visit 11) i.v. Infusions
    The peripheral blood for each participant was collected and analyzed for tmax.
    Clearance of Ofa Over the Course of Weeks 0-2 and 24-26
    The peripheral blood for each participant was collected and analyzed for clearance. Clearance is the measure of efficiency with which a drug is irreversibly removed form the body. The average clearance over the course of Weeks 0-2 and 24-26 is reported.
    The Volume of Distribution at Steady State (Vss) of Ofatumumab Over the Course of Weeks 0-2 and 24-26
    The peripheral blood for each participant was collected and analyzed for Vss. The average Vss over the course of Weeks 0-2 and 24-26 is reported.
    Half Life (t1/2) of Ofatumumab in the Terminal Elimination Phase Over the Course of Weeks 0-2 and 24-26
    The peripheral blood for each participant was collected and analyzed for half life. Half life is defined as the period of time required for the amount of drug in the body to be reduced by half. The average t1/2 over the course of Weeks 0-2 and 24-26 is reported.

    5. Study Description

    Brief Summary
    The trial consists of a dose escalation, to establish the safety of ofatumumab in RRMS patients. A 48-week treatment period followed by an individualized follow-up period until normalization of peripheral B-cell counts or Immunoglobulin G (IgG) levels.
    Detailed Description
    The trial consists of two phases, a 48 week treatment period, followed by an individualized treatment period of up to two years. Patients are treated in cohorts of increasing doses (100 mg, 300 mg and 700 mg) with 12 patients in each dose cohort. Within each cohort patients are randomized asymmetrically in a 2:1 ratio such that eight patients will receive ofatumumab and four patients will receive placebo. After 24 weeks the patients randomized to placebo will be treated with the active dose for the cohort. For blinding purposes, patients randomized to the active dose will be treated with placebo after 24 weeks. Thus, each patient will receive two administrations of trial product with 24 weeks follow-up resulting in a total treatment period of 48 weeks duration. An Independent Data Monitoring Committee (IDMC) will review and evaluate the safety data of each cohort, a minimum of 4 weeks data including the week 4 Magnetic Resonance Imaging (MRI) from at least 10 patients, to consider if progression to the next higher dose cohort is acceptable. The trial product is administered as two infusions separated by two weeks. Clinical assessment and Gadolinium enhanced (Gd-enhanced) MRI scan will be performed at weeks -4, 0, 2, 4, and every 4 weeks until week 48. The MRI scan at week 2 is carried out for safety assessment prior to administering the second infusion in the first treatment course. When patients in all dose cohorts have been dosed and have had week 4 MRI scans performed, an IDMC will review all available safety data. After completion of week 48 patients will be followed to monitor B-cell and IgG normalization. B-cell levels will be monitored every 12 weeks until CD19+ cells have returned to baseline level (Visit 3) or normalized level. If the B-cell levels are not normalized after two years the patient should be followed until either the IgG or the B-cell levels are normalized (see Section 9.2.4 for details). During this period Gd-enhanced MRI follow up scans will be performed every 12 weeks to evaluate potential rebound, safety and for Progressive Multifocal Leukoencephalopathy (PML) monitoring.
