NCT ID:
NCT06940804
Brief Summary:
This study is designed to evaluate the safety, efficacy, cellular kinetics, and immunogenicity of Claudin 6 (CLDN6) Chimeric antigen receptor T cell (CAR-T) ± CLDN6 ribonucleic acid-lipoplex (RNA-LPX) in participants born male with relapsed or refractory CLDN6-positive testicular or extragonadal germ cell tumors (GCTs) after prior salvage therapy.
Detailed Description:
The study will consist of two parts. The Safety Lead-in Part will evaluate safety and tolerability of CLDN6 CAR T ± CLDN6 RNA-LPX therapy in three arms with different dosing regimens. In the Safety Lead-in Part, participants will be randomized in a 1:1:1 ratio. Data from the Safety Lead-in Part up to the cut off will be used to select the dose for the single-arm Main Part of the study.
To increase the potency of the transferred CAR-T cells, a lymphodepleting chemotherapy regimen (comprising fludarabine and cyclophosphamide) will be administered in participants prior to infusion of CLDN6 CAR-T.
It is expected that it will take approximately 28 months for each participant to complete screening, apheresis, pre-treatment, treatment, and primary follow-up.
Participants who receive a CLDN6 CAR-T infusion will complete the long-term follow-up (LTFU) to assess safety and efficacy of the CLDN6 CAR-T treatment for a total of 15 years after CLDN6 CAR-T infusion. No investigational medicinal product (IMP) will be administered during the LTFU.
