About this study

Official title: A Phase I/II Study Evaluating the Safety, Tolerability, Pharmacokinetics and Anti-Tumor Activity of TRS005 in Combination With Cyclophosphamide, Doxorubicin, and Prednisone(T-CHP) in Previously Untreated Patients With CD20-positive DLBCL

This trial is a multicenter, open-label, single-arm, dose-escalation and dose-expansion clinical trial. The dose was increased according to the "3 + 3" rule. Patients with previously untreated patients with CD20-positive DLBCL were selected to evaluate the safety, tolerance (DLT, MTD), pharmacokinetics, and anti-tumor activity of TRS005 in combination with standard doses of cyclophosphamide, doxorubicin, and prednisone(T-CHP) by intravenous drip every 3 weeks.

Medical subject headings

  • CyclophosphamideDrug

    Cyclophosphamide will be administered at 750 milligrams per square meter (mg/m^2) IV every 3 weeks (starting from Cycle 1 Day 1), for 6 cycles.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Part I: Dose Limiting Toxicities (DLTs) and Maximum Tolerated Dose (MTD)

    All dose-escalation cohorts will consist of at least 3 participants. If a DLT is observed in 1 participant at a given dose level during the DLT observation period before dose escalation, additional participants will be enrolled at that dose level for a total of at least 6 participants. DLT assessment forms part of determining the Maximum Tolerated Dose (MTD). The highest dose level resulting in DLTs in less than one-third of a minimum of 6 participants will be declared the MTD.

    Measured: Cycle 1 Day 1 (C1D1) to Cycle 1 Day 21 (C1D21)

  2. Part I and II: Adverse Events

    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. AEs were reported based on the national cancer institute common terminology criteria for AEs, Version 5.0 (NCI-CTCAE, v5.0). Reported are the number of subjects with AEs, Grade 3-5 AEs, and Serious Adverse Events (SAEs).

    Measured: Day 1 up to approximately 6 months

Secondary outcomes (6)
  1. Overall Response Rate (ORR)

    The overall response rate (ORR) was defined as the proportion of participants achieving complete response (CR) or partial response (PR) based on Lugano 2014 criteria

    Measured: At the end of treatment (Month 6)

  2. Duration of Response (DOR)

    Duration of Overall Response (DOR), estimated using the Kaplan Meier method, is measured from Lugano 2014 criteria are met for CR or PR (whichever is first recorded) , until the first date that recurrent or progressive disease is objectively documented. Patients without progressive disease are censored at the date of last disease assessment.

    Measured: Up to 24 months

  3. Progression-Free Survival (PFS)

    Progression-free survival based on the Kaplan-Meier method is defined as the duration between randomization and documented disease progression (PD) per Lugano criteria or death, or is censored at time of last disease assessment.

    Measured: Up to 24 months

  4. Overall Survival (OS)

    Overall Survival (OS) based on the Kaplan-Meier method is defined as the time from study entry to death or censored at date last known alive.

    Measured: Up to 24 months

  5. Immunogenicity

    ADA will be assessed in all participants. NAb will be assessed in samples that are ADA positive.

    Measured: At the end of treatment (Month 6)

  6. Serum concentration

    Total TRS005, TRS005 unconjugated MMAE, and antibody-conjugated Mono-Methyl Auristatin E [acMMAE]

    Measured: At the end of cycle 4 (each cycle is 21 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TRS005, Cyclophosphamide and Doxorubicin in people with Diffuse Large B-Cell Lymphoma (DLBCL), run by Zhejiang Teruisi Pharmaceutical Inc. 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 9 inclusion and 16 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: opening soon, as of the sponsor's last update on 22 Aug 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 Chen Wang ((+86)18832374527, chen.wang@teruisipharm.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part I: Dose Limiting Toxicities (DLTs) and Maximum Tolerated Dose (MTD) (time frame: Cycle 1 Day 1 (C1D1) to Cycle 1 Day 21 (C1D21)). 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 22 Aug 2025.
