About this trial
The purpose of this clinical trial is to assess the feasibility, safety and efficacy of anti-GD2/PSMA bi-specific CAR-T cell therapy in patients with GD2 and PSMA positive tumor. Another goal of the study is to learn more about the function of the anti-GD2/PSMA bi-specific CAR-T cells and their persistency in patients.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients with tumors have received standard first-line therapy and have been judged to be non-resectable, metastatic, progressive or recurrent.
The expression status of GD2 or PSMA 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 PSMA-specific CAR T cells or antibody therapy.
Active HIV, Hepatitis B virus (HBV), Hepatitis C virus (HCV) infection or uncontrolled infection.
