Detailed Description

This is a single-center, open-label, single-arm study to evaluate the safety and preliminary efficacy of anti-CDH17 CAR-T cells in patients with CDH17-positive advanced solid tumors.A leukapheresis procedure will be performed to manufacture Anti-CDH17 chimeric antigen receptor (CAR) modified T cells. Prior to Anti-CDH17 CAR-T cells infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide. After infusion, the safety and efficacy of CAR-T therapy was evaluated by investigators.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

What is the study measuring?
