简要总结
This clinical study is to investigate the safety and tolerability of CAR modified autologous T cells (CCT301-59) in subjects with recurrent or refractory solid tumors.
详细描述
This is a single arm, open label, dose escalation clinical study to evaluate the safety and preliminary therapeutic efficacy of CCT301-59 T cells in adult subjects with relapsed and refractory stage IV metastatic solid tumors (soft tissue sarcoma, gastric cancer, pancreatic cancer, bladder cancer etc.).
The subjects with ROR2 (receptor tyrosine kinase-like orphan receptor 2) positive biopsy will receive CCT301-59.
According to the 3+3 rules during the dose escalation stage to receive CCT301-59 treatment.
