About this study

Official title: Immunotherapy for Peritoneal Carcinomatosis (IPC) - A Phase I Study of the Safety and Efficacy of Anti-CEA CAR-T Cell Intraperitoneal Infusions for Treatment of CEA-Expressing Adenocarcinoma Peritoneal Metastases or Malignant Ascites

This is an open-label, dose-escalation, phase I trial of the safety and efficacy of anti-CEA intraperitoneal CAR-T infusions for treatment in patients with CEA-expressing adenocarcinoma peritoneal metastases or malignant ascites.

Read the detailed description

Patients undergo leukapheresis from which peripheral blood mononuclear cells are purified. T cells are activated and then re-engineered to express chimeric antigen receptors (CARs) specific for CEA. Cells are expanded in culture and returned to the patient by intraperitoneal infusion at specific cell doses. One anti-CEA CAR-T dose per patient is planned. Additional cycles may be administered at the discretion of the principal investigator. Normal peritoneal and tumor biopsies will be obtained at the time of the CAR-T infusion, on the final day of the treatment period, and during reporting interval #3.

What is being measured

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

  1. Safety of Intraperitoneal CAR-T Cell Infusions as Measured by Number of Participants with Adverse Events

    To determine the safety and maximum tolerated dose (MTD) following intraperitoneal infusion(s) of anti-CEA CAR-T cells for inoperable CEA+ peritoneal metastases or malignant ascites.

    Measured: 16 weeks

Secondary outcomes (8)
  1. Progression-Free Survival

    As a measure of activity, Progression-free survival (PFS) will be assessed. The events for the assessment of PFS are disease progression and death events

    Measured: 20 weeks

  2. Overall Survival

    As a measure of activity, Overall Survival (OS) will be assessed. The events for the assessment of OS are death events.

    Measured: 20 weeks

  3. Bowel Obstruction Free Survival

    Measuring the time frame in which a patient does not experience a bowel obstruction

    Measured: 20 weeks

  4. Changes in Quality of Life

    Changes in quality of life measured by Quality of Life Index (IQI) survey pre and post-treatment

    Measured: 20 weeks

  5. Response by the Peritoneal Carcinomatosis Index (PCI)

    Direct visualization of tumor burden assessment by the PCI pre and post-treatment

    Measured: 16 weeks

  6. Radiographic treatment response by MRI

    Changes in tumor size

    Measured: 20 weeks

  7. Radiographic treatment response by PET

    Changes in tumor metabolic activity

    Measured: 20 weeks

  8. Serologic response rates

    Measurement of CEA and CA19-9

    Measured: 20 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing anti-CEA CAR-T cells in people with Peritoneal Carcinomatosis and Peritoneal Metastases, run by Sorrento Therapeutics, Inc. at 2 sites in United States.

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 6 inclusion and 21 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: withdrawn, as of the sponsor's last update on 6 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Safety of Intraperitoneal CAR-T Cell Infusions as Measured by Number of Participants with Adverse Events (time frame: 16 weeks). 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 6 Apr 2022.
