About

New York Esophageal Squamous Cell Carcinoma 1 (NY-ESO-1) is a cancer-testis antigen (CTA) which is expressed in various tumors. In TCR-T therapy, researchers take the blood of a certain patient, select T cells and insert genes into the cell that expressing a kind of protein that targeting NY-ESO-1. The genetically engineered cells are called NY-ESO-1 TCR-T cells. Then the engineered cells are re-infused to the cancer patients to cure the disease or prolong life.

Full 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.

Objective:

To evaluate the safety and efficacy of TCR-T cells for the treatment of advanced solid tumors.

Eligibility:

Adults aging 18-70 with advanced solid tumors

Design:

Patients will undergo screening tests, including imaging procedures, heart and lung tests, and lab tests.

Patients will have leukapheresis. Blood will be removed through a needle in the arm. A machine separates the white blood cells. The rest of the blood is returned through a needle in the other arm.

Engineered T cells will be re-infused into the patient. Patients will stay in hospital and be evaluated

Enrollment: 18 estimated patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers

Trial design

Primary purpose: Treatment

Allocation: N/A

Interventional model: Single Group Assignment

Masking: None (Open label)

18 participants in 1 patient group

dose escalation

Experimental group

Description:

This study uses the "3+3" dose escalation method. The initial dose is Dose 1, the maximum dose that patients can tolerate is determined as the phase II recommended dose (RPIID), and at least 6 patients are receiving RPIID treatment. If patients develop intolerance in Dose 1 (≥3 subjects with DLT), then the subsequent enrolled patients will receive Dose -1 infusion.
