• Clinical chemistry and/or hematology laboratory values of clinical concern, in the investigator's opinion.

For subjects transitioning directly from the OPV116910 study, review central chemistry and hematology laboratory reports from the Week 48 through Week 56 visits of OPV116910.

For subjects transitioning from the Individualized Follow-up Period of OPV116910, review central chemistry and hematology laboratory reports from the most recent OPV116910 Individualized Follow-up visit. If the date of that laboratory report is more than 12 weeks from the extension study Screening visit, then the laboratory assessments need to be repeated.

For subjects with neutropenia (absolute neutrophil count <1 Giga units per liter, the neutropenia must resolve before the first dose of ofatumumab, which should occur within 4 weeks of the screening assessments.

• Electrocardiogram (ECG) showing a clinically significant abnormality or showing a Corrected QT Interval (QTc) interval >=450 millisecond (msec) (>=480 msec for subjects with bundle branch block) (ECG will be obtained during Week 60 visit of OPV116910; Repeat ECG if more than 12 weeks have elapsed).

• Significant concurrent, uncontrolled medical condition that could affect the subject's safety, impair the subject's reliable participation in the study, impair the evaluation of endpoints, or necessitate the use of medication not allowed by the protocol.

• In the Investigator's opinion, there is a reason why the subject would not be eligible for this study (eg, the subject is unable to comply with the visit schedule).

Study Results

Participant Flow

Recruitment Details	This study was a multicounty, multicenter, open-label extension study to assess the long-term efficacy and safety of ofatumumab subcutaneous (SC) injection in participants with pemphigus vulgaris (PV), who completed the core study period of study OPV116910.
Pre-assignment Detail	The study consisted of a screening visit, followed by a 56-week treatment period, a 4-week follow-up visit and a minimum of 1 year (up to 2 years) of individualized follow-up. Only 1 participant was enrolled into the study due to study termination.

Arm/Group Title	Ofatumumab
Arm/Group Description	At Baseline and Week 4 visits, participants were planned to receive 40 milligrams (mg) ofatumumab SC (2 X 20 mg); and 20 mg ofatumumab SC injections every 4 weeks from Week 8 through Week 56. Participants planned to return to clinic 4 weeks after the last dose for a Follow-up visit (Week 60). Antihistamine 10 mg and acetaminophen/paracetamol 1 grams (g) would be given 1-2 hours before and 4 hour after each dose of ofatumumab SC injection. Acetaminophen/paracetamol 1 g were to be self administered. Prednisone/prednisolone dose were to be tapered during core study period by 1 dose level every 2 weeks to <= 10 mg/day from Baseline through Week 60. Upon completion of the core study period, participants were to enter individualized Follow-up period, where participants were to be monitored every 12 weeks for a minimum of 1 year and up to 2 years.
