About this study

Official title: A Phase I/IIa Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of TST001 - Claudin18.2 Monoclonal Antibody in the Treatment of Locally Advanced or Metastatic Solid Tumors

This is an open-label, multi-center, Phase I trial of TST001. Subjects with locally advanced or metastatic solid tumors will be enrolled. The study will consist of two parts: Part A is dose escalation and dose expansion phase for mono-therapy, and Part B is dose escalation and dose expansion phase for combination therapy in gastric, gastroesophageal junction(G/GEJ) and biliary tract cancer, etc.

Read the detailed description

There are two parts in the study. Part I is mono-therapy dose escalation and dose expansion study, and Part II is dose escalation and dose expansion study of combination therapy.

The dose escalation study will be conducted utilizing 3+3 design with two dosing regimens, i.e. "once every 2 weeks (Q2W)" and "once every 3 weeks (Q3W)".

After MTD/RP2D determined, three cohorts may be included in the expansion plan, with about 30 (20-40) subjects with positive CLDN18.2 expression be treated in each cohort, as shown below (during the study, the treatment cohorts may be adjusted or added based on the clinical and pre-clinical study data).

Approximately 320-540 treated subjects in total

What is being measured

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

  1. Participant Safety as characterized by frequency and severity of adverse events(according to NCI CTCAE 5.0).

    An AE is any untoward medical occurrence in a subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

    Measured: up to 30 days following last dose.

  2. Maximum Tolerated Dose (MTD）

    The maximum tolerated dose (MTD) is commonly estimated to be the maximum dose that can be determined through DLT of two among 6 subjects administered with TST001 Q2W in 28 days cycles.

    Measured: up to 28 days following first dose

  3. Maximum Tolerated Dose (MTD）

    The maximum tolerated dose (MTD) is commonly estimated to be the maximum dose that can be determined through DLT of two among 6 subjects administered with TST001 once every 3 weeks in 21 days cycles.

    Measured: up to 21days following first dose

  4. Recommended Phase 2 Dose (RP2D)

    The RP2D will be determined during the dose expansion stage of the study. RP2D will be determined using available safety and efficacy data.

    Measured: up to 30 days following last dose

  5. The incidence and case number of DLT (Dose Limiting Toxicity) in subjects administered with TST001 Q2W in 28 days cycles during observation period

    DLT is short for Dose Limiting Toxicity. dose-limiting describes side effects of a drug or other treatment that are serious enough to prevent an increase in dose or level of that treatment.

    Measured: up to 28 days following first dose

  6. The incidence and case number of DLT (Dose Limiting Toxicity) in subjects administered with TST001 once every 3 weeks in 21 days cycles during observation period

    DLT is short for Dose Limiting Toxicity. dose-limiting describes side effects of a drug or other treatment that are serious enough to prevent an increase in dose or level of that treatment.

    Measured: up to 21days following first dose

  7. Safety and Tolerability of TST001 in combination with other therapies, e.g. CAPOX, paclitaxel, GP, nivolumab as characterized by frequency and severity of adverse events

    Characterization of TST001 + CAPOX safety profile including frequency and severity of adverse events that are related to treatment.

    Measured: Up to 30 or 90 days following last dose

Secondary outcomes (9)

  1. Area under plasma concentration vs time curve (AUC) for TST001

    Changes in AUC over time in participants with TST001.

    Measured: up to 30 days following last dose

  2. Peak plasma concentration (Cmax) for TST001

    Cmax is the maximum plasma concentration.

    Measured: up to 30 days following last dose

  3. Time to maximum observed plasma concentration (Tmax)

    Tmax is the time in hrs/days it takes to reach Cmax after dosing with TST001

    Measured: up to 30 days following last dose

  4. Terminal elimination half life (t1/2)

    Time for the plasma level of TST001 to decrease b y 1/2 during the terminal elimination phase.

    Measured: up to 30 days following last dose

  5. Immunogenicity

    by measurement of Incidence of anti-drug antibodies (ADA)

    Measured: up to 30 days following last dose

  6. Objective response rate (ORR)

    as measured by RECIST 1.1

    Measured: up to 30 days following last dose

  7. Duration of Response (DOR)

    DOR is defined as the time from the date of the first response CR (complete remission)/PR (partial remission) (whichever is first recorded) to the date of radiographical progression/death or date of censoring.

    Measured: up to 30 days following last dose

  8. Disease Control Rate

    DCR: CR+PR+SD

    Measured: up to 30 days following last dose

  9. Progression free survival (PFS) and OS

    as measured by RECIST v1.1

    Measured: up to 30 days following last dose

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TST001, Oxaliplatin and Capecitabine in people with Advanced Cancer, run by Transcenta Therapeutics (Hangzhou) Co., Ltd. at 40 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 32 inclusion and 41 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: under way, not looking for participants, as of the sponsor's last update on 29 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 40 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 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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Participant Safety as characterized by frequency and severity of adverse events(according to NCI CTCAE 5.0). (time frame: up to 30 days following last dose.). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04495296.

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 29 Sep 2026.
