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.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 66 participants
Allocation: Non-Randomized
Intervention Model: Factorial Assignment
Intervention Model Description: Subjects with ROR2 positive biopsy will receive CCT301-59. Subjects with AXL positive biopsy that are ROR2 negative will receive CCT301-38.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Dose Escalation and Dose Expansion Trial to Assess the Safety, Tolerability and Anti-tumor Activity of Autologous T Cell Modified Chimeric Antigen Receptor (CAR) CCT 301-38 or CCT 301-59 in Patients With Recurrent or Refractory Stage IV Renal Cell Carcinoma
Actual Study Start Date : March 26, 2018
Estimated Primary Completion Date : June 30, 2022
Estimated Study Completion Date : June 30, 2023


Arm Intervention/treatment
Experimental: 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.
Biological: CCT301-59
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.

Experimental: 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.
Biological: CCT301-38
Subjects will undergo blood draw to isolate peripheral blood mononuclear cells (PBMCs) for the production of CCT301-38. During CCT301-38 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 CCT301-38 by intravenous (IV) injection.
