TCR-T Cells for the Treatment NY-ESO-1-positive Advanced Solid Tumors

A Single-arm, Open-label, Dose-finding Clinical Study of TCR-T Cells in Patients With HLA-A2-expressing and NY-ESO-1-positive Recurrent or Metastatic Solid Tumors

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.

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.

4. ECOG score of 0-1;
5. Patients with recurrent or metastatic solid tumors confirmed by histopathology;
6. Subjects who failed standard treatment in the past or have no standard treatment currently tor who are judged by the investigator to be unsuitable for current standard treatment for other reasons, and the objective imaging assessment is disease progression;
7. According to RECIST 1.1 standard, there is at least one measurable target lesion for efficacy evaluation;
8. NY-ESO-1 positive;
9. HLA type is HLA-A2 (except HLA-A*0203);

5. Patients who have received adoptive cell therapy in the past;
6. According to the judgment of the investigator, the condition of the subject is not suitable for this trial.
