    Measured: Pre-dose, 5 minutes, 24, 72, 120 and 168 hours post dose on day 1 of cycles 2, 4; pre-dose, 5 minutes post dose on day 1 of cycles 3, 8; once at the end of treatment, each cycle is 21 days

  9. Apparent volume of distribution at terminal phase (Vz)

    The volume of body fluid required to distribute the drug in the body according to the plasma drug concentration at this time after the drug distribution in the plasma and tissues has reached equilibrium.

    Measured: Pre-dose, 5 minutes, 24, 72, 120 and 168 hours post dose on day 1 of cycles 2, 4; pre-dose, 5 minutes post dose on day 1 of cycles 3, 8; once at the end of treatment, each cycle is 21 days

  10. Trough plasma concentration (Cmin)

    Maximum blood concentration achieved by drug administration.

    Measured: Pre-dose, 5 minutes, 24, 72, 120 and 168 hours post dose on day 1 of cycles 2, 4; pre-dose, 5 minutes post dose on day 1 of cycles 3, 8; once at the end of treatment, each cycle is 21 days

  11. Anti-drug antibody (ADA ) incidence

    Immunogenicity test: Anti-drug antibody (ADA ) incidence.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TQB2825 Injection + Gemcitabine Hydrochloride for Injection + Oxaliplatin for Injection in people with Diffuse Large Cell B-lymphoma, run by Shanghai Chia Tai Tianqing Pharmaceutical Technology Development Co., Ltd. at 24 sites 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 11 inclusion and 27 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 24 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites 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 Qingqing Cai, Doctor (13798101121, caiqq@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complete response rate (CR rate) (time frame: 1 year). 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 24 Mar 2025.
