About this study

Official title: Chimeric Antigen Receptor T Lymphocytes (CAR-T) Targeting CEA in the Treatment of CEA Positive Clinical Study of Advanced Malignant Solid Tumors

This study is a single-arm, open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of CEA-targeted CAR-T cell preparations, and to preliminarily observe the study drug in CEA-positive advanced malignant tumors. The pharmacokinetic characteristics of CAR-T cell preparations for the treatment of patients with CEA-positive advanced malignancies were obtained and the recommended dose and infusion schedule.

Read the detailed description

According to the different infusion methods, it is divided into two subgroups: intravenous infusion and local infusion through the peritoneal cavity. Each subgroup includes a dose exploration stage (Part A) and a dose expansion stage (Part B). 3 patients were explored, starting from the low-dose group, and in the dose expansion phase, the safety and efficacy were further verified according to the safe recommended dose obtained in the dose exploration phase.

Being tested

What is being measured

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

  1. To evaluate the safety of CAR-T cell preparations in the treatment of CEA-positive advanced malignancies [Safety and Tolerability]

    The incidence of adverse events after CEA CAR-T cell infusion was assessed by the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, version 5.0)

    Measured: 1 month

  2. Obtained the recommended dose and infusion regimen of CAR-T cells for the treatment of patients with CEA-positive advanced malignancies[Safety and Tolerability]

    Dose-limiting toxicity after CEA CAR-T cell infusion

    Measured: 28 days

Secondary outcomes (5)
  1. Assessing disease control rates of CAR-T cell preparations in CEA-positive advanced malignancies[Effectiveness]

    Disease control rate: The proportion of subjects who achieved CR, PR, SD after CAR-T infusion accounted for all treated subjects (Assessed based on RECIST criteria),the minimum value is 0%,maximum value is 100%, and higher scores mean a better outcome.

    Measured: 3 months

  2. AUCS of CEA CAR-T cells [Cell dynamics]

    AUCS is defined as the area under the curve in 90 days

    Measured: 3 months

  3. CMAX of CEA CAR-T cells [Cell dynamics]

    CMAX is defined as the highest concentration of CEA CAR-T cells expanded in peripheral blood

    Measured: 3 months

  4. TMAX of CEA CAR-T cells[Cell dynamics]

    TMAX is defined as the time to reach the highest concentration

    Measured: 3 months

  5. Pharmacodynamics of CEA CAR-T cells[Cell dynamics]

    The content of CEA in peripheral blood was detected by ELISA at the visit points specified in the research protocol

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing CEA-targeted CAR-T cells in people with Gastric Cancer and Colon Cancer, run by Chongqing Precision Biotech Co., Ltd at 3 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 17 inclusion and 17 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 9 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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?

Results are not available in the source record.

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

Contact Qi Mei, M.D (15871708675, borismq@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To evaluate the safety of CAR-T cell preparations in the treatment of CEA-positive advanced malignancies [Safety and Tolerability] (time frame: 1 month). 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 9 Aug 2024.
