About this study
This study aims to investigate the predictive value of PET imaging targeting granzyme B on the outcome of patients with diffuse large B lymphoma receiving immunotherapy.
Read the detailed description
The investigators will number all participants, create a medical record file, and record their basic information (gender, age) as well as contact information and medical history information. All participants will undergo 68Ga-grazytracer PET at baseline and after one course of immunotherapy (CAR-T, Glofitamab or iR2 ).

Questions about this trial
What is this clinical trial studying?
An observational study of 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 3 inclusion and 4 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 1 Jan 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.
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 Xinyi Zhu (19121913585, zxy16zz@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The value of PET imaging targeting granzyme B in predicting the efficacy of immunotherapy for diffuse large B-cell lymphoma (time frame: Baseline and 2 weeks after treatment). The study lists 2 primary outcomes in all. 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 1 Jan 2025; AzTrials last refreshed its copy on 26 Oct 2026.
