Study Details

Detailed Description
This study is a multi-center retrospective observational study. It aims to evaluate the effectiveness and safety of polatuzumab vedotin treatment in patients with hematopoietic stem cell transplantation ineligible relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL), who met the criteria to access Pola through the compassionate use program (CUP). Based on the medical records of patients in the four participating hospitals, the study database will be established by using the unified case report form (CRF) to search extract information the data of target population from the hospital database, that is, the variables without personal identification information.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Pola BR/R Patients with R/R DLBCL who are enrolled in the Pola CUP program in China, and treated with Pola-BR or Pola-R regimens. |
Drug: Polatuzumab Vedotin-Piiq
Patients will receive a total of six cycles of Pola in combination with rituximab and bendamustine or in combination with only rituximab. A cycle is typically 21 days for DLBCL.

Outcome Measures
Primary Outcome Measures
- Investigator-assessed best overall response (BOR) [From the start of the treatment until the date of first documented progression or the completion of the treatment(up to six cycles, each cycle is 21 days)]
Best overall response (BOR) assessed by the investigator, is based on either PET-CT or CT, and defined as the percentage of patients with CR or PR.
Secondary Outcome Measures
- Objective response rate (ORR) [At end of the treatment(up to six cycles, each cycle is 21 days)]
Objective response rate (ORR) assessed by the investigator at the end of treatment (EOT), is defined as the percentage of patients with CR or PR at the end of treatment.
- Duration of response (DOR) [From initial CR or PR to disease progression, relapse, or death from any cause, whichever occurred first, assessed up to 25 months]
DOR is defined as the time from initial complete response (CR) or partial response (PR) to disease progression, relapse, or death from any cause, whichever occurred first.
- Complete response (CR) [At end of the treatment(up to six cycles, each cycle is 21 days)]
CR rate is defined as the percentage of patients with CR.
- Progression free survival (PFS) [From the start of treatment until disease progression, relapse, or death from any cause, whichever occurred first,assessed up to 30 months]
PFS is defined as the time from the start of treatment until disease progression, relapse, or death from any cause, whichever occurred first.
