About this trial

The purpose of this study is to assess the feasibility, safety and efficacy of GD2/CD70 bi-specific CAR-T cell therapy in patients with GD2 and/or CD70 positive tumor. Another goal of the study is to learn more about the function of the GD2/CD70 bi-specific CAR-T cells and their persistency in patients.

Eligibility criteria

Qualifiers

Patients with tumors received standard first-line therapy and judged to be non-resectable, metastatic, progressive or recurrent.

The expression status of GD2 or CD70 antigens in the tumor tissue will be determined for eligibility. Positive expression is defined by GD2 and PMSA antibody staining results based on immunohistochemistry or flow cytometry analyses.

Body weight greater than or equal to 10 kg.

Age: ≥1 year and ≤ 75 years of age at the time of enrollment.

Disqualifiers

Existing severe illness (e.g. significant cardiac, pulmonary, hepatic diseases, etc.) or major organ dysfunction, or greater than grade 2 hematologic toxicity.

Untreatable central nervous system (CNS) metastasis: Patients with previous CNS tumor involvement that has been treated and is stable for at least 6 weeks following completion of therapy are eligible.

Previous treatment with other genetically engineered GD2 or CD70-specific CAR T cells.

Active HIV, hepatitis B virus (HBV), hepatitis C virus (HCV) infection or uncontrolled infection.
