Brief Summary

This is a two arm, open-label, dose escalation and dose expansion clinical study to evaluate the safety and efficacy of infusion of autologous CCT301-38 or CCT 301-59 T cells in adult subjects with relapsed and refractory stage IV metastatic renal cell carcinoma.Subjects with ROR2 positive biopsy will receive CCT301-59. Subjects with AXL positive biopsy that are ROR2 negative will receive CCT301-38.

Conditions

• Allocation Method: NON_RANDOMIZED
• Intervention Model: FACTORIAL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

CCT301-59

The safety and efficacy of CCT301-59 will be evaluated for subjects with ROR2 positive biopsy in a standard 3+3 dose escalation approach. 3 CAR T dosage will be tested in this study: 1×10\^5/kg, 1×10\^6/kg, 1×10\^7/kg CAR+ T cells.

Group Type: EXPERIMENTAL

CCT301-59

Intervention Type: BIOLOGICAL

Subjects will undergo blood draw to isolate peripheral blood mononuclear cells (PBMCs) for the production of CCT301-59. During CCT301-59 production, subjects will receive a conditioning chemotherapy regimen of cyclophosphamide and fludarabine for the purpose of lymphocyte depletion. After lymphodepletion, subjects will receive one dose treatment with CCT301-59 by intravenous (IV) injection.

CCT301-38

The safety and efficacy of CCT301-38 will be evaluated for subjects with AXL positive but ROR2 negative biopsy in a standard 3+3 dose escalation approach. 3 CAR T dosage will be tested in this study: 1×10\^5/kg, 1×10\^6/kg, 1×10\^7/kg CAR+ T cells.

Group Type: EXPERIMENTAL
