简要总结
Considerable progress in the treatment of metastatic melanoma has been made in the past 5years, with the approval of immune checkpoint-blocking antibodies and agents targeting BRAF mutation. Investigators conducted a open label, dose escalation, phase I clinical trial of to explore the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of intravenous administration of autologous NKT Cells in metastatic melanoma patients.
详细描述
Considerable progress in the immunotherapy of metastatic melanoma has been made in the past 5 years, with the approval of immune checkpoint-blocking antibodies. NKT cells are a potent immunoregulatory cell population heavily implicated in promoting immunity to infection and cancer. And now with new generation of amplification method, more than 1,000 folds amplification of NKT cells can be obtained, so NKT cell based adoptive cell transfer is now available and might show its efficacy in melanoma. Investigators conducted this open label, dose escalation, phase I clinical trial of to explore the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of intravenous administration of autologous NKT Cells in metastatic melanoma patients.

结局指标
主要结局
Number of subjects experiencing at least one dose limiting toxicity (DLT) of intravenous administration of autologous NKT Cells in metastatic melanoma patients.
时间窗: 252 days
DLT is defined as any of the following toxicities assessed as at least possibly related to NKT cells by the investigator up to 28 days each cycle(up to 8 cycles,with 28 days' safety and efficacy follow-up after the end of the last cycle) after the end of adoptive transfer: any Grade greater than or equal to (\>=) 3 non-hematological toxicity, but excluding the conditions mentioned in the protocol; any Grade 4 neutropenia of greater than (\>)5 days duration or Grade \>=3 febrile neutropenia; any Grade 4 thrombocytopenia or Grade 3 thrombocytopenia with bleeding; any Grade 4 anemia.
