Clinical Trial Summary

The goal of this clinical trial is to explore the efficacy and safety of autologous iNKT cells in patients with progressed hepatocellular carcinoma (HCC) after treatment with PD-1 antibody. The main question it aims to answer are:

• the efficacy of autologous iNKT cells in patients with progressed HCC after treatment with PD-1 antibody.

• the safety of autologous iNKT cells in patients with progressed HCC after treatment with PD-1 antibody.

Participants will be randomized 1:1 to receive Regorafenib + PD-1 + iNKT cells (RPI group) or the treatment of Regorafenib + PD-1 (RP group).

Researchers will compare RPI group and RP group to see whether the iNKT cells can achieve a better therapeutic effect on HCC patients with PD-1 resistance.

Description:

Single center, randomized, open trial in Barcelona Clinic Liver Cancer（BCLC）C stage patients with progressed HCC after anti-angiogenic targeted drugs combined with PD-1 monoclonal antibody therapy to explore the efficacy and safety of autologous iNKT cells.

This study includes screening period, treatment period and follow-up period (until the subjects withdrew their informed consent or received other anti-tumor therapy or participated in other clinical trials or the researchers judged that it is not in the best interests of patients to continue to participate in the study) after treatment.

The patients will be randomized 1:1 using a random number table to receive Regorafenib + PD-1 + iNKT cells (RPI group) or the treatment of Regorafenib + PD-1 (RP group).

1. iNKT Cells：Intravenous infusion. The cells will be infused every two weeks as a course of treatment for up to six courses.

2. PD-1：Intravenous infusion, according to the drug instructions.

3. Regorafenib：Oral administration, according to the drug instructions. All target and non-target lesions will be assessed by chest, abdomen, and pelvis CT or MRI at baseline and every 8 weeks until radiological progression (according to mRECIST/iRECIST).

Safety and side-effect profiles will be assessed based on the nature, frequency, and severity of adverse events, according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 5.0.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-Free Survival (PFS)	The time from enrollment to disease progression according to the modified RECIST (mRECIST) guideline in trial immunotherapeutics, or death from any cause, whichever occurred first;the time from enrollment to confirmed disease progression (iCPD) according to the iRECIST	The time from enrollment to disease progression, or death from any cause, whichever occurred first, up to 24 months.
Secondary	Disease control rate (DCR)	including complete response (CR), partial response (PR), and disease stabilization (SD), evaluated by imaging according to iRECIST for target lesions and assessed by MRI/CT.	Evaluation was performed every 8 weeks after the start of the treatment, up to 24 months.
Secondary	Objective response rate (ORR)	complete response (CR) and partial response (PR) evaluated by imaging according to mRECIST/iRECIST for target lesions and assessed by MRI/CT.	Evaluation was performed every 8 weeks after the start of the treatment, up to 24 months.
Secondary	Overall survival (OS)	Time from the date of enrollment to the date of death from any cause.	Time from the date of enrollment to the date of death from any cause, up to 36 months.
Secondary	1-year overall survival rate (1-year OS rate)	The proportion of subjects who were still alive from the date of enrollment to 1 year later	Time from the date of enrollment to 1 year later.
Secondary	Duration of Overall Response (DOR)	The time from the first tumor remission (CR or PR according to mRECIST/iRECIST) to the first recording of disease progression (PD according to mRECIST criteria or iCPD according to iRECIST) or death from any cause (whichever occurs first).	Time from the first tumor remission to the first recording of disease progression or death from any cause, up to 24 months..
Secondary	Time to progression (TTP)	Time from the date of enrollment to the date of first disease progression (PD) according to mRECIST or iCPD according to iRECIST).	Time from the date of enrollment to the date of first disease progression, up to 24 months.
Secondary	Time to Quality of Life (QoL) Deterioration	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.	Time from the date of enrollment, up to 24 months.
