- Brief Summary
This is a Phase I, multicenter, open-label, dose-escalation study of polatuzumab vedotin administered as a single agent by intravenous (IV) infusion to participants with relapsed or refractory hematologic malignancies.

Group Intervention Description Polatuzumab Vedotin Polatuzumab Vedotin Polatuzumab vedotin will be administered by an IV infusion of escalating doses (starting dose of 0.1 mg/kg, potentially to be followed by 0.25 mg/kg, 0.5 mg/kg, 1.0 mg/kg, 2.0 mg/kg, and 4.0 mg/kg doses) every 3 weeks (q3w) (Day 1 of each 21 day cycle). Polatuzumab Vedotin + Rituximab Polatuzumab Vedotin Polatuzumab vedotin will be administered by an IV infusion q3w (Day 1 of each 21 day cycle). Rituximab was administered by an IV infusion at 375 milligrams per square meter (mg/m\^2) body surface area dose q3w. Polatuzumab Vedotin + Rituximab Rituximab Polatuzumab vedotin will be administered by an IV infusion q3w (Day 1 of each 21 day cycle). Rituximab was administered by an IV infusion at 375 milligrams per square meter (mg/m\^2) body surface area dose q3w.
