Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Investigator-assessed best overall response (BOR)
Time Frame: 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.
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)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Objective response rate (ORR)
Time Frame: 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.
At end of the treatment(up to six cycles, each cycle is 21 days)
Duration of response (DOR)
Time Frame: 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.
From initial CR or PR to disease progression, relapse, or death from any cause, whichever occurred first, assessed up to 25 months
Complete response (CR)
Time Frame: 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.
At end of the treatment(up to six cycles, each cycle is 21 days)
Progression free survival (PFS)
Time Frame: 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.
From the start of treatment until disease progression, relapse, or death from any cause, whichever occurred first,assessed up to 30 months
