简要总结
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. In Phase Ib, participants will receive polatuzumab vedotin in combination with rituximab.

研究组 & 干预措施
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).
干预措施: Polatuzumab Vedotin (Drug)
Polatuzumab Vedotin + 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.
干预措施: Polatuzumab Vedotin (Drug)
Polatuzumab Vedotin + Rituximab
