- Brief Summary
Hepatocellular carcinoma (HCC) is a common disease with high mortality. More than 80% patients receive a diagnosis when their tumors are too advanced for curative approaches and have a dismal prognosis. invariant Natural Killer T (iNKT) cell exhibit antitumor activity against malignant tumors through producing high levels of cytokines. iNKT cells are abundant in the liver, but their function is defective in liver cancer. After expansion and restored function in vitro, iNKT cells can home to liver, then they play key antitumor function. We have finished a phase I study of adoptive transfer of autologous iNKT cells for treating patients with unresectable HCC. Safety and feasibility of iNKT infusion was proved. The purpose of this study was to verify the effectiveness of iNKT cell infusion in patients with unresectable HCC who had previously failed transcatheter arterial embolization (TAE) / transcatheter arterial chemoembolization (TACE).
- Detailed Description
Patients with unresectable HCC will be enrolled and divided into two groups. Patients in trial group will be treated with combination of TAE/TACE and adoptive transfer of autologus iNKT cells. TAE/TACE will be performed at 0th and 4th week. iNKT cells will be infused at 1st, 3rd, 5th, 7th, 9th, 11th week after first TAE/TACE therapy. Patients in control group will be treated with TAE/TACE at 0th and 4th week. Overall survival (OS) time, progression-free survival (PFS) time, objective response rate(ORR), disease control rate(DCR) will be monitored.
According to JSH guidelines, TAE/TACE failure is defined as an insufficient response after ≧2 consecutive TAE/TACE procedures that is evident on response evaluation computed tomography or magnetic resonance imaging after 1-3 months, these patients do not respond sufficiently to TAE/TACE.

Group Intervention Description TAE/TACE+iNKT for unresectable HCC iNKT cells TAE/TACE combined with autologous iNKT cells infusion will be applied for patients in experimental group. TAE/TACE will be performed at 0th and 4th week. 5×10\^8-10\^9/m2 iNKT cells will be infused to patients at 1st, 3rd, 5th, 7th, 9th, 11th week after first TAE/TACE therapy. TAE/TACE+iNKT for unresectable HCC Human recombinated Interleukin-2 TAE/TACE combined with autologous iNKT cells infusion will be applied for patients in experimental group. TAE/TACE will be performed at 0th and 4th week. 5×10\^8-10\^9/m2 iNKT cells will be infused to patients at 1st, 3rd, 5th, 7th, 9th, 11th week after first TAE/TACE therapy. TAE/TACE+iNKT for unresectable HCC TAE/TACE TAE/TACE combined with autologous iNKT cells infusion will be applied for patients in experimental group. TAE/TACE will be performed at 0th and 4th week. 5×10\^8-10\^9/m2 iNKT cells will be infused to patients at 1st, 3rd, 5th, 7th, 9th, 11th week after first TAE/TACE therapy. TAE/TACE for unresectable HCC TAE/TACE TAE/TACE will be conducted at 0th week and 4th week.
- Primary Outcome Measures
Name Time Method Progression-Free Survival(PFS) From date of enrollment to disease progression according to mRECIST, or death from any cause, whichever occurred first，approximately 2 years. PFS is the duration from the date of enrolled into clinical trial to the date of first documentation of tumor progression.
Progression is defined using Modified RECIST (mRECIST),as an increase of at least 20% in the sum of the diameters of viable (enhancing) target lesions, taking as reference the smallest sum of the diameters of viable (enhancing) target lesions recorded since treatment started.
- Secondary Outcome Measures
Name Time Method Overall Survival(OS) From date of randomization until the date of death from any cause, whichever came first, assessed up to 60 months. OS is the duration from the date of enrollment to the date of death due to any causes.
Objective Response Rate(ORR) Evaluation was performed at the 12th week after the start of the treatment. ORR is the proportion of patients who had a response rate including complete remission (CR) and partial remission (PR) evaluated by imaging according to mRECIST for target lesions and assessed by MRI/CT: Complete Response (CR), Disappearance of any intratumoral arterial enhancement in all target lesions；Partial Response (PR), At least a 30% decrease in the sum of diameters of viable (enhancement in the arterial phase) target lesions, taking as reference the baseline sum of the diameters of target lesions; Overall Response (OR) = CR + PR.
Disease Control Rate (DCR) Evaluation was performed at the 12th week after the start of the treatment. DCR is the proportion of patients who had a response rate including complete remission (CR), partial remission (PR) and disease stabilization (SD) evaluated by imaging according to mRECIST for target lesions and assessed by MRI/CT: Complete Response (CR), Disappearance of any intratumoral arterial enhancement in all target lesions；Partial Response (PR), At least a 30% decrease in the sum of diameters of viable (enhancement in the arterial phase) target lesions, taking as reference the baseline sum of the diameters of target lesions;Stable disease(SD), Any cases that do not qualify for either partial response or progressive disease. Disease Control Rate (DCR) = CR + PR + SD.
Adverse Events(AEs) The occurrence of AEs was observed for an average of 24 weeks after the completion of treatment (between 0-11 weeks of treatment) for up to a 60 week period in total. The severities of AEs will be divided into 5 levels according to the National Cancer Institute (NCI) Common Terminology Standard for Adverse Events (CTCAE) version 4.03.
Time to Quality of Life (QoL) Deterioration Data will be collected at baseline and every 4 weeks until disease progression, then every 8 weeks for up to 60 weeks. EORTC QLQ-C30: European Organization for Research on Treatment of Cancer Quality of Life Questionnare-Core 30.
The totally 30 items spread out over five functional scales (15 items), three symptom scales (7 items), a global health status/QoL scale (2 items), and six single items. 1-28 item ranges 1: not at all, 2: a little, 3: quite a lit, 4: very much; 29-30 item ranges 1-7 from very poor to excellent. Raw score (RS) is an average of all items in each area. Standardized score is in the range of 0-100 by formula SS=\[1-(RS-1)/n\] x100 (function) or SS=\[（RS-1）/n\]x100 (symptom or overall health) respectively. A high scale score represents a higher/healthy response level.
Time to deterioration was defined as a decrease from baseline of 10 points or more on the EORTC QLQ-C30 maintained for two consecutive assessments.
