Primary Outcome Measures :
  1. Number of patients that experience an adverse event or abnormal laboratory, vital and/or ECG results and positive suicidiality outcomes [ Time Frame: Up to 5 years ]

Secondary Outcome Measures :
  1. Number of relapse rates per year [ Time Frame: Core studies up to 5 years from first dose of ofatumumab (depending on if first dose was in the core or in this extension study or comparator randomization) ]
    Annual Relapse Rate (ARR) time calculated as number of confirmed relapses divided by time in study per year and will also be presented for the entire duration

  2. Patients with confirmed 3 and 6 month disability worsening [ Time Frame: Duration of the study, approximately 5 years ]
    A confirmed disability worsening is an increase from baseline in Expanded Disability Status Scale (EDSS) score sustained for at last 3, or 6 months EDSS consists of seven functional systems and an ambulation score that are then combined to determine the EDSS steps (ranging from 0 (normal) to 10 (death due to MS)). The functional systems are Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel and Bladder, and Cerebral functions (Fatigue contributes).

  3. Patients with confirmed 6, 12 and 24 month disability improvement and improvement until end of study [ Time Frame: Duration of the study, approximately 5 years ]
    Confirmed disability improvement is a decrease from baseline in Expanded Disability Status Scale (EDSS) score sustained for at least 6, 12 or 24 months EDSS consists of seven functional systems and an ambulation score that are then combined to determine the EDSS steps (ranging from 0 (normal) to 10 (death due to MS)). The functional systems are Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel and Bladder, and Cerebral functions (Fatigue contributes).

  4. Patients with changes in Expanded Disability Status Scale (EDSS) scores [ Time Frame: Core studies up to 5 years from first dose of ofatumumab (depending on if first dose was in the core or in this extension study or comparator randomization) ]
    Score changes in Expanded Disability Status Scale (EDSS) over time EDSS consists of seven functional systems and an ambulation score that are then combined to determine the EDSS steps (ranging from 0 (normal) to 10 (death due to MS)). The functional systems are Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel and Bladder, and Cerebral functions (Fatigue contributes).

  5. Changes in and time to 6 month confirmed worsening of Symbol Digit Modalities Test Scores [ Time Frame: Duration of the study, approximately 5 years ]
    Score changes and confirmed 4-point worsening sustained for 6 months in Symbol Digit Modalities Test (SDMT) scores The Symbol Digit Modalities Test is a neuropsychological, timed test for sustained attention and concentration. 3 versions will be used, alternating at each visit where done. The number of correct responses will be counted for the score.

  6. Changes in the Magnetic Resonance Image (MRI) related to brain volume loss [ Time Frame: Core studies up to 5 years from first dose of ofatumumab (depending on if first dose was in the core or in this extension study or comparator randomization) ]
    Percent change from baseline in brain volume loss (BVL)

  7. Changes in the Magnetic Resonance Image (MRI) related to T2 lesions [ Time Frame: Core studies up to 5 years from first dose of ofatumumab (depending on if first dose was in the core or in this extension study or comparator randomization) ]
    Number of new or enlarging T2 lesions

  8. Changes in the Magnetic Resonance Image (MRI) related to Gd-enhancing lesions [ Time Frame: Core studies up to 5 years from first dose of ofatumumab (depending on if first dose was in the core or in this extension study or comparator randomization) ]
    Total number of Gd-enhancing lesions on all MRI scans adjusted for different time of scan versus follow up time in study

  9. Changes in neurofilament light change serum concentration [ Time Frame: Core studies up to 5 years from first dose of ofatumumab (depending on if first dose was in the core or in this extension study or comparator randomization) ]
    Extent of neurofilament light change concentration in blood NfL is a component of the neuronal cytoskeleton and is released into the cerebrospinal fluid and into subsequently blood following neuro-axonal damage
