Study Endpoints
Primary Endpoints
Area Under the Serum Concentration-time Curve From Time 0 to Infinity (AUCinf) After the Second Infusion of the First Dose
Day 15, pre-dose, end of infusion, and 3, 6, 24, and 48 hours, and 2, 6, and 10 weeks postdose.

Area under the serum concentration-time curve from time 0 extrapolated to infinity (AUCinf) following the second infusion of the first dose (day 15). Concentrations of ABP-798 and rituximab were quantified using a validated electrochemiluminescent method. AUCinf was estimated using the linear trapezoidal rule.

Maximum Observed Drug Concentration (Cmax) After the Second Infusion of the First Dose
Day 15, pre-dose, end of infusion, and 3, 6, 24, and 48 hours, and 2, 6, and 10 weeks postdose.

Maximum observed concentration following the second infusion of the first dose (day 15). Concentrations of ABP-798 and rituximab were quantified using a validated electrochemiluminescent method.

Secondary Endpoints
Area Under the Serum Concentration-time Curve From Predose on Day 1 to 14 Days Postdose (AUC0-14day)
Day 1, predose, at end of infusion, 3, 6, 24, and 48 hours postdose and day 15, predose.
Area Under the Serum Concentration-time Curve From Predose on Day 1 to Week 12 (AUC0-12wk)
Day 1, predose, at end of infusion, 3, 6, 24, and 48 hours postdose; day 15, predose, end of infusion, 3, 6, 24, and 48 hour postdose, and at days 29, 57, and 85 (week 12).
Maximum Observed Drug Concentration (Cmax) After the First Infusion of the First Dose
Day 1, predose, at end of infusion, 3, 6, 24, and 48 hours postdose and day 15, predose.

ABP 798 / ABP 798EXPERIMENTALParticipants received ABP 798 on days 1 and 15 (dose 1) and a second dose of ABP 798 at weeks 24 and 26 (dose 2). Each dose consisted of two 1000 mg intravenous infusions 2 weeks apart.
Rituximab (US) / ABP 798ACTIVE_COMPARATORParticipants received rituximab (United States \[US\] formulation) on days 1 and 15 (dose 1) and transitioned to receive ABP 798 at weeks 24 and 26 (dose 2). Each dose consisted of two 1000 mg intravenous infusions 2 weeks apart.
Rituximab (EU) / Rituximab (EU)ACTIVE_COMPARATORParticipants received rituximab (European Union \[EU\] formulation) on days 1 and 15 (dose 1) and a second dose of rituximab (EU formulation) at weeks 24 and 26 (dose 2). Each dose consisted of two 1000 mg intravenous infusions 2 weeks apart.
