Primary Outcome Measures
NameTimeMethod
Area under the concentration time curve (AUC)From baseline to 12 weeks

AUC is defined as the area under the plot of plasma concentration of Epratuzumab against time after administration per subject.

All measurements taken in the study (at administration day \[day 0, 7, 14, 21\] and the next four days of each administration day and week-4, 6, 8, 10, 12) are used to calculate AUC

Half-life (t1/2)From baseline to 12 weeks

Half-life is defined as the time taken for plasma concentrations of Epratuzumab to decline by one half per subject.

All measurements taken in the study (at administration day \[day 0, 7, 14, 21\] and the next four days of each administration day and week-4, 6, 8, 10, 12) are used to calculate Half-life.

Maximum plasma Concentration (Cmax)From Baseline to 12 weeks

Plasma concentration of Epratuzumab for each pharmacokinetics parameter is measured at administration day (day 0, 7, 14, 21) and the next four days of each administration day and week-4, 6, 8, 10, 12.

Secondary Outcome Measures
NameTimeMethod
Incidence of anti-epratuzumab in plasma during administration over 12 weeksDay 0 (initial administration day) and week 12 (end of the evaluation period)

Blood drawing for anti- epratuzumab is carried out at initial administration day (day 0) and end of the evaluation period (week 12).
