Design outcomes

Primary

MeasureTime frameDescription
overall response rate (ORR)through study completion, an average of 2 yearsEffectiveness of polatuzumab vedotin plus rituximab (± bendamustine) in patients with relapsed or refractory DLBCL who have received at least one dose of polatuzumab vedotin plus rituximab (± bendamustine) under the NPP (D.M. 7 Sep 2017) in the period between June 2019 and Feb 2020 in Italy. This value is calculated as the sum of partial (PRR) and complete response rates (CRR) at end of treatment.
