Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
In all 3 dose cohorts, participants in the active/placebo group received treatment with ofatumumab during the First Treatment Period and placebo during the Second Treatment Period. Whereas participants in the placebo/active group received treatment with placebo during the First Treatment Period and ofatumumab during the second treatment period.

Reporting Groups
  Description
100 Milligrams (mg) Ofatumumab (Ofa)/Matching Placebo Ofa was administered as two doses of 100 mg via intravenous (iv) infusions separated by 2 weeks (wks) during the first 24-wk treatment period. Matching placebo was administered as two iv infusions separated by 2 wks during the second 24-wk treatment period. An Independent Data Monitoring Committee (IDMC) evaluated the safety data at Week 4 for participants receiving the 100 mg dose before considering progression to the 300 mg dose.
300 mg Ofa/Matching Placebo Ofa was administered as two doses of 300 mg via iv infusions separated by 2 wks during the first 24-wk treatment period. Matching placebo was administered as two iv infusions separated by 2 wks during the second 24-wk treatment period. An IDMC evaluated the safety data at Week 4 for participants receiving the 300 mg dose before considering progression to the 700 mg dose.
700 mg Ofa/Matching Placebo Ofa was administered as two doses of 700 mg via iv infusions separated by 2 wks during the first 24-wk treatment period. Matching placebo was administered as two iv infusions separated by 2 wks during the second 24-wk treatment period.
Matching Placebo/100 mg Ofa Matching placebo was administered as two iv infusions separated by 2 wks during the first 24-wk treatment period. Ofa was administered as two doses of 100 mg via iv infusions separated by 2 wks during the second 24-wk treatment period.
