Brief summary
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.
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.
Interventions
Subiects who meet the enrollment conditions will receive intravenous infusion of anti-CDH17 CAR-T Cells after lymphodepleting therapy.

Eligibility
Inclusion criteria
1. The patient understands and voluntarily signs the informed consent form, and is expected to complete the follow-up examination and treatment of the study procedures; 2. Age 18-75 years old, gender unlimited; 3. Tumor patients who have positive expression of CDH17 target in tumor tissues measured by immunohistochemistry (IHC) in a laboratory approved by the partner, and have no standard therapy or are ineffective or not suitable for standard treatment; 4.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of adverse events(AE) after infusion | within 52 weeks post-infusion | The frequency, severity, and laboratory findings of all adverse events/serious adverse events are included.Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome are graded by American Society for Transplantation and Cellular Therapy (ASTCT) criteria. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Objective Response Rate (ORR) | within 52 weeks post-infusion | 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. |
| Concentration of CAR-T cells | Days 2, 5, 8, 11, 14, 21, 28, 35 and weeks 6, 12, 18, 26, 34, 42, 52 after infusion | Concentration of CAR-T cells measured by Flow cytometry after CAR-T infusion |
| Progression-free survival(PFS) | within 52 weeks post-infusion | Progression-free survival(PFS) refers to the time from cell reinfusion to the first assessment of tumor progression or death from any cause. |
| Overall survival(OS) | within 52 weeks post-infusion | Overall survival (OS) refers to the time from the time the patient received an infusion of CAR-T cells until death (from any cause). |
