2. There is no gender requirement but age requirement (age>18) for the subjects who sign the informed consent.
3. The subjects were diagnosed as advanced hepatocellular carcinoma (HCC) by imaging or histological examination.
4. The disease is not suitable for radical surgery and/or local treatment, or disease progression occurs after surgery and/or local treatment.
5. The patients with at least one measurable lesion according to RECIST, version1.1, and no local radiotherapy was performed. Results of spiral CT scan (RECIST, version 1.1): LD (lesion) ≥ 10 mm or SD (enlarged lymph node) ≥ 15 mm.
6. The patients who failed or were intolerable to the following treatments: simple sorafenib therapy, or sorafenib combined with PD-1 therapy, or simple lenvatinib therapy, or lenvatinib combined with PD-1 therapy, or bevacizumab combined with atezolizumab.
7. Definition of treatment failure: It refers to the disease progression during treatment or the recurrence of the disease after treatment (Obvious disease recurrences and progressions appeared in patients who have received at least one radical or palliative resection, interventional therapy or radiotherapy. The treatment period of systemic chemotherapy like oxaliplatin and other systemic chemotherapy must be at least one cycle. The treatment time of molecular targeted therapy must be longer than 14 days).
8. Definition of intolerable: Hematological toxicity ≥ Grade IV, or non-hematological toxicity ≥ Grade III, or damage to the heart, liver, kidney and other major organs ≥ Grade II occurred during the treatment. For details, please refer to the package inserts of each drug.
9. The ECOG score within 1 week before enrollment was 0-1 points.
10. Child-Pugh score for liver function: Class A, BCLC staging is B-C stage.
11. The time from failure of first-line system treatment to enrollment in this study (the time to sign the informed consent form) was ≥ 2 weeks , and the adverse events basically returned to normal (NCI-CTCAE ≤ Grade I).
12. The expected survival time is greater than or equal to 6 months.
13. HBV DNA < 2000 IU/ml (104 copies/ml).

14. Hematology and organ function are adequate, based on the following laboratory test results obtained within 14 days prior to the start of study treatment (unless otherwise stated):

    14.1 Routine blood test: (No blood transfusion, G-CSF treatment, or medication correction within 14 days prior to screening) 14.2 Hb ≥ 100 g/L; Neutrophils ≥ 1.5 × 109/L; PLT ≥ 75 × 109/L 14.3 Biochemical examination: (No ALB was administered within 14 days) ALB ≥ 35 g/L; ALT and AST<3×ULN; TBIL ≤ 2×ULN; Creatinine ≤ 1.5×ULN; PT ≤ ULN+4S; INR ≤ 2.2 (In the Child-Pugh score, only one of albumin and bilirubin can be scored as 2 points)

15. No active autoimmune disease requiring systemic treatment in the past 2 years (i.e. using disease modulators, corticosteroids, or immunosuppressive agents). Alternative therapy (e.g., physiological corticosteroid replacement therapy for thyroxine, insulin, or adrenal or pituitary insufficiency, etc.) is not considered as a form of systemic therapy.

16. Reproductive women: Agree to abstain from sex (avoid heterosexual intercourse) or use a contraceptive method with an annual contraceptive failure rate < 1% during treatment and for at least 6 months after the last administration.

    16.1 If the female patient has menstruation and has not yet reached the post-menopausal state (continuous non-menstrual period ≥ 12 months, with no other reasons other than menopause are found), and have not undergone sterilization (removal of the ovaries and/or uterus), it is considered that the patient is fertile.

    16.2 Examples of contraceptive methods with an annual contraceptive failure rate < 1% include bilateral fallopian tube ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices and copper-ring intrauterine devices.

    16.3 The reliability of sexual control should be evaluated relative to the duration of the clinical trial and the preferred and daily lifestyle of the patient. Periodic abstinence (for example, calendar days, ovulatory period, symptomatic body temperature, or post-ovulation methods) and external ejaculation are unacceptable methods of contraception.

17. Male: Agree to abstinence (not having heterosexual intercourse) or use contraceptive measures, and agree not to donate sperm, defined as follows:

    17.1 When his female partner has fertility, the male patient must abstain from sex during treatment and within 6 months after the last administration, or use condoms and other contraceptive methods to make the annual contraceptive failure rate < 1%. Male patients must agree not to donate sperm during the same time period. When his female partner is pregnant, the male patient must abstain from sex or use a condom for contraception during the treatment period and within 6 months after the last dose to avoid the fetus being affected by the study.

18. The reliability of sexual control should be evaluated relative to the duration of the clinical trial and the preferred and daily lifestyle of the patient. Periodic abstinence (for example, calendar days, ovulatory period, symptomatic body temperature, or post-ovulation methods) and external ejaculation are unacceptable methods of contraception.
19. Before the first dose of study medication for biomarker analysis, archived tumor tissue or new tissue biopsy specimens must be available. In the case when the archived tissue cannot be provided, and the biopsy cannot be performed, participants can consult the investigator and join the group after obtaining the investigator's consent.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Regorafenib plus PD-1 inhibitor; Regorafenib (BAY 73-4506, Stivarga®) is an oral diphenylurea multi-kinase inhibitor that targets angiogenic (VEGFR1-3, TIE2), stromal (PDGFR-β, FGFR), and oncogenic receptor tyrosine kinases (KIT, RET, and RAF). Camrelizumab (AiRuiKa™), a programmed cell death 1 (PD-1) inhibitor being developed by Jiangsu Hengrui Medicine Co. Ltd, recently received conditional approval in China for the treatment of relapsed or refractory classical Hodgkin lymphoma. Toripalimab, a recombinant, humanized programmed death receptor-1 (PD-1) monoclonal antibody that binds to PD-1 and prevents binding of PD-1 with programmed death ligands 1 (PD-L1) and 2 (PD-L2), is being developed by Shanghai Junshi Bioscience Co., Ltd in China for the treatment of various cancers. Pembrolizumab (Keytruda) the programmed cell death protein 1 (PD1) is one of the checkpoints that regulates the immune response. Ligation of PD1 with its ligands PDL1 and PDL2 results in transduction of negative signals to T-cells.

Drug: Regorafenib; Regorafenib, 120 mg, once a day, 3 weeks on/1 week off; Other Names: BAY 73-4506, Stivarga; Drug: PD-1 inhibitor; Camrelizumab: 200mg (BW ≥ 50 kg) or 3 mg/kg (BW < 50 kg) Toripalimab: 240mg is given through intravenous drip every 3 weeks on Day 1 of each course of treatment. Pembrolizumab: 200mg is given through intravenous drip every 3 weeks.; Other Names: Camrelizumab (AiRuiKa™)、Toripalimab、Pembrolizumab(Keytruda)
