• Conditions: Solid Tumors
• Interventions: Biological: TCR-T cells; Drug: Fludarabine; Drug: Cyclophosphamide Capsules; Drug: Albumin-bound paclitaxel; Drug: IL-2

• Registration Number: NCT05648994
• Lead Sponsor: Fujian Cancer Hospital

Brief Summary

New York Esophageal Squamous Cell Carcinoma 1 (NY-ESO-1) is a Cancer-Testis Antigen (CTA) which is expressed in various tumors. After selected the high affinity TCR gene to NY-ESO-1, the researchers insert genes into the cell that expressing a kind of protein that targeting NY-ESO-1. Then the engineered cells are re-infused in the patients with tumors for curing the tumor patient or prolonging life.

Detailed Description

This is a single-center, open-label, Phase I clinical study of TCR-T cells for the treatment of the recurrent/metastatic solid tumors patients who had failed standard therapy.

TCR-T cells are expanded from peripheral blood, and after ex vivo modification, and extensive expansion, are reinfused to patients after non-myeloablative lymphocyte-depleting preparative regimen.

The primary purpose of this study is to evaluate the safety and tolerability of TCR-T cells in patients with recurrent/metastatic solid tumors.

The second purpose of this study is to preliminarily explore the effectiveness of TCR-T cells in patients with recurrent/metastatic solid tumors.

Eligibility:

Adults aging 18-70 who were failed to standard treatment or have no standard treatment with recurrent/metastatic solid tumors.
