Trial summary

Recurrence of liver metastasis in colorectal cancer after R0 resection is mainly due to the invisible minimal residual disease, which are the main factors leading to metastasis and recurrence. Positive circulating tumor DNA (ctDNA) is the direct evidence of the minimal residual disease (MRD). Read more about this study

About this study

Official title: A Clinical Study to Evaluate the Safety and Efficacy of Anti-CEA CAR-T Cells in the Treatment of Postoperative Minimal Residual Lesions in Colorectal Cancer Patients With Liver Metastases

Recurrence of liver metastasis in colorectal cancer after R0 resection is mainly due to the invisible minimal residual disease, which are the main factors leading to metastasis and recurrence. Positive circulating tumor DNA (ctDNA) is the direct evidence of the minimal residual disease (MRD). In recent years, Chimeric Antigen Receptor T-Cell Immunotherapy (CAR-T) has made great breakthroughs, and has achieved good therapeutic effects in hematological tumors, but the research on solid tumors is limited. CEA expression is generally elevated in gastrointestinal tumors and is associated with high aggressiveness of tumors. At present, solid tumor cell therapy targeting CEA has been carried out at home and abroad, and has achieved certain efficacy. Anti-CEA CAR-T cells targeting CEA have been constructed in the pre-clinical study of this project, and the pre-clinical study results suggest good safety and effectiveness. Formation of minimal residual disease is associated with circulating blood in the residual tumor cells. Using this feature, this project intends to conduct a phase I clinical study on patients with minimal residual disease /positive ctDNA after R0 resection of colorectal cancer liver metastasis, so as to conduct preliminary exploration of anti-CEA CAR-T cell therapy, evaluate the safety and effectiveness of the therapy, determine the maximum tolerated dose (MTD), and provide guidance for subsequent drug dosage and clinical trials.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Anti-CEA CAR-T CellsDrug

    The study will evaluate the safety of intravenous infusion of anti-CEA CAR-T (+) cells in humans at doses of 1×10^6/kg, 3×10^6/kg, and 6×10^6/kg using a standard "3+3" design and preliminarily observe the efficacy.

Study groupRoleWhat they receive
MRD or positive ctDNA patients to inject anti-CEA CAR-T cellsExperimentalPatients with liver metastasis of colorectal cancer after R0 surgery and adjuvant chemotherapy could not clear MRD (including patients with MRD still positive after the intermediate and final evaluation of adjuvant chemotherapy, and patients with MRD positive again after the end of adjuvant chemotherapy), and no measurable lesions or tumor remnants were found on imaging after surgery.
Receives: Drug: Anti-CEA CAR-T Cells

What is being measured

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

  1. Security (Incidence and severity of adverse events)

    To evaluate the possible reatment related adverse events(TEAEs) occurred within the first 28 days after anti-CEA CAR-T infusion, including replicative lentiviruses(RCL), anti-drug antibody(ADA), and the incidence and severity of symptoms such as cytokine release syndrome(CRS) and CAR-T related encephalopathy syndrome(CRES).

    Measured: Observation 28 days after CAR-T cells infusion

  2. Effectiveness (minimal residual disease)

    Recurrence by ctDNA MRD detection or imaging diagnosis

    Measured: 24 months after R0 resection

  3. Efficacy (recurrence-free survival)

    2-year recurrence-free survival rate based on imageological examination.

    Measured: 2 years after CAR-T cells infusion

Secondary outcomes (2)
  1. Pharmacokinetics (PK) indicator (Cmax)

    The peak concentration of anti-CEA CAR-T cells amplified in the peripheral blood (Cmax, detected by flow cytometry and qPCR).

    Measured: 2 years after CAR-T cells infusion

  2. Pharmacokinetics (PK) indicator (AUC)

    The exposed quantity of anti-CEA CAR-T cells amplified in the peripheral blood(aera under the curve, AUC, detected by flow cytometry and qPCR).

    Measured: 2 years after CAR-T cells infusion

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Anti-CEA CAR-T Cells in people with Colorectal Cancer and Metastatic Liver Cancer, run by Changhai 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 14 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 11 Mar 2022. 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?

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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Security (Incidence and severity of adverse events) (time frame: Observation 28 days after CAR-T cells infusion). The study lists 3 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 11 Mar 2022.
