About this study

Official title: Exploratory Study to Evaluate the Safety and Preliminary Efficacy of Anti-CDH17 CAR-T Cell Injection in Patients With CDH17-positive Advanced Malignant Solid Tumors

This is a single-arm, open-label, exploratory clinical study to evaluate the safety and preliminary efficacy of Anti-CDH17 CAR-T cell injection in patients with CDH17-positive advanced malignant solid tumors.

Read the detailed description

This study will include two parts, dose escalation phase (accelerated titration and 3+3 design) followed by a dose expansion phase.

All eligible participants will receive a conditioning chemotherapy regimen of fludarabine and cyclophosphamide followed by Anti-CDH17 CAR-T cell injection.

The dose escalation phase will determine the maximum tolerated dose (MTD) of Anti-CDH17 CAR-T cell injection. Additional patients will be enrolled in the dose expansion phase to further characterize the safety profile and evaluate the efficacy of Anti-CDH17 CAR-T cell injection, and establish recommended phase 2 dose (RP2D).

What is being measured

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

  1. Adverse Events (AEs)

    Incidence and severity of adverse events.

  2. Serious Adverse Events (SAEs)

    Incidence and severity of serious adverse events.

    Measured: 2 years

  3. Adverse Events of Special Interest (AESI)

    Measured: 2 years

  4. Identification of Maximum Tolerated Dose (MTD) & Incidence of Dose-limiting Toxicities (DLTs)

    Measured: 4 weeks after the CAR-T cells infusion

Secondary outcomes (7)

  1. Objective Response Rate (ORR)

    The Objective Response Rate (ORR) is the percentage of participants who achieved Complete Response (CR) or Partial Response (PR) based on RECIST version 1.1.

    Measured: 2 years

  2. Disease Control Rate (DCR)

    Disease control rate (DCR) is the percentage of participants who achieved Complete Response (CR) or Partial Response (PR) or Stable disease (SD) based on RECIST version 1.1.

    Measured: 2 years

  3. Progression-Free Survival (PFS)

    PFS is defined as the time from CAR-T infusion to the date of the disease progression or death from any cause.

    Measured: 2 years

  4. Overall Survival (OS)

    OS is defined as the time from CAR-T infusion to the date of death due to any cause.

    Measured: 2 years

  5. Bio-distribution of CAR-T cells

    CAR copies will be measured by qPCR to evaluate the expansion and persistence of CAR-T cells in vivo. Cmax, Tmax, AUC0-tlast and AUC0-inf of CAR copies will be analyzed.

    Measured: 2 years

  6. Cytokine Level in Peripheral Blood

    Level of cytokines (IL-2、IL-6、IL-8、IL-10、TNF-α and IFN-γ, etc.) in serum.

    Measured: 2 years

  7. Anti-drug Antibodies

    Number of participants with anti-drug antibodies.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Anti-CDH17 CAR-T cells in people with CDH17-positive Advanced Malignant Solid Tumors, run by Shanghai Pudong 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 9 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: status not confirmed, as of the sponsor's last update on 15 Jul 2024. 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 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.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Zhiguo Long (18117253161, zglong1976@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse Events (AEs) (time frame: 2 years). The study lists 4 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 NCT06501183.

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 15 Jul 2024.
