What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-free survival（by IRC）
PFS, defined as the time from randomization to the first occurrence of disease progression or relapse using the 2014 Lugano Response Criteria or death due to any cause, whichever occurs first; as determined by the investigator
Measured: From randomization to the first occurrence of disease progression or relapse, or death from any cause, whichever occurs earlier (up to 24 months)
Secondary outcomes (6)
Progression-free survival（by the investigator）
PFS, defined as the time from randomization to the first occurrence of disease progression or relapse using the 2014 Lugano Response Criteria or death due to any cause, whichever occurs first; as determined by the investigator
Measured: From randomization to the first occurrence of disease progression or relapse, or death from any cause, whichever occurs earlier (up to 24 months)
Event-free survival
defined as the time from date of randomization to the earliest occurrence of any of the following:
Disease progression/relapse as determined by the investigator and IRC (separately) Death due to any cause The primary efficacy reason determined by the investigator, other than disease progression/relapse, that leads to initiation of NALT If biopsy is obtained after treatment completion and is positive for residual disease regardless of whether NALT is initiated or not
Measured: up to approximately 24 months
Complete response rate
CR rate at the end of treatment by FDG-PET defined as the proportion of participants with CR at the end of treatment according to the 2014 Lugano Response Criteria; as determined by the investigator and IRC (separately)
Measured: End of treatment visit (6-8 weeks after last dose on Day 1 of Cycle 6 [Cycle length=21 days]
Objective response rate
ORR at treatment completion or discontinuation defined as the proportion of participants with partial response (PR) or CR at the end of treatment according to the 2014 Lugano Response Criteria; as determined by the investigator and IRC(separately)
Measured: End of treatment visit (6-8 weeks after last dose on Day 1 of Cycle 6 [Cycle length=21 days]
Overall survival
OS defined as the time from randomization to death from any cause
Measured: up to approximately 3 years
Number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE v5.0
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
Measured: From enrollment to study completion, a maximum of 3 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Polatuzumab vedotin, Rituximab and Cyclophosphamide in people with Diffuse Large B-Cell Lymphoma, run by Ruijin Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Weili Zhao (+862164370045 ext. 610707, zwl_trial@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival（by IRC） (time frame: From randomization to the first occurrence of disease progression or relapse, or death from any cause, whichever occurs earlier (up to 24 months)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Dec 2025.
