Cryoablation Combined With Camrelizumab and Apatinib in Advanced Hepatocellular Carcinoma

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the efficacy and safety of cryoablation combined with pd-1 antibody immunotherapy (Camrelizumab) and anti-angiogenesis therapy (Apatinib) in patients with advanced hepatocellular carcinoma (HCC).

Detailed Description
-----------------
This is a prospective, single arm, phase 2 study to evaluate the efficacy and safety of cryoablation combined with Camrelizumab and Apatinib (C-couple Therapy) in patients with advanced HCC. Subjects who meet the admission criteria will be treated with Camrelizumab and Apatinib after cryoablation until disease progression, intolerable toxicity, death, withdrawal of the patient or the researchers determined that the drug must be discontinued. The primary outcome measure is to evaluate the objective response rate (ORR) of C-couple Therapy for advanced HCC (BCLC C-stage). The secondary outcome measures include the duration of response (DOR), disease control rate (DCR), progression-free survival rate (PFSR) in 6- and 12-months, overall survival rate (OSR) in 6- and 12-months, the median progression-free survival time (mPFS) and median overall survival time (mOS) of C-couple Therapy for advanced HCC. This study also aims to assess the safety and adverse reactions of C-couple Therapy for advanced HCC.

If it is still positive after the re-examination, a gastroscopy is required. If the gastroscope shows severe esophageal and gastric varices, it cannot be included in the group (3 before the group) Except those who have undergone gastroscopy within a month or less to exclude such cases); Arterial/venous thrombosis events that occurred within 6 months before randomization, such as cerebrovascular accidents (including temporary ischemic attacks, cerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism; Known genetic or acquired bleeding and thrombotic tendency (such as hemophilia patients, coagulation dysfunction, thrombocytopenia, etc.); Urine routine test showed urine protein ≥ ++ and confirmed 24-hour urine protein content> 1.0 g; Patients who have previously received radiotherapy, chemotherapy, hormone therapy, and surgery, after the completion of the treatment (last medication) and less than 4 weeks before the study medication; molecular targeted therapy (including other oral targeted drugs used in clinical trials) is less than the first study medication <5 drug half-lives, or patients whose adverse events (except alopecia) caused by previous treatment have not recovered to ≤ CTCAE level 1; The patient has active infection, fever of unknown origin within 7 days before medication ≥38.5℃, or baseline white blood cell count >15×109/L; Patients with congenital or acquired immune deficiencies (such as HIV-infected persons); Patients with HBV DNA>2000 IU/ml (or 104 copies/ml), HCV RNA>103 copies/ml, HBsAg+ and anti-HCV antibody positive; The patient suffered from other malignant tumors in the past 3 years or at the same time (except for cured skin basal cell carcinoma and cervical carcinoma in situ); Patients with bone metastases who received palliative radiotherapy within 4 weeks before participating in the study >5% of the bone marrow area; The patient has previously received other anti-PD-1 antibody therapy or other immunotherapy against PD-1/PD-L1, or has previously received apatinib therapy; Live vaccine may be vaccinated less than 4 weeks before study medication or may be administered during the study period; According to the judgment of the investigator, the patient has other factors that may affect the results of the study or cause the study to be terminated halfway, such as alcoholism, drug abuse, other serious diseases (including mental illness) that require combined treatment, and serious laboratory tests Abnormalities, accompanied by family or social factors, will affect the safety of patients.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Objective response rate (ORR) by RECIST 1.1 and mRECIST | ORR is defined as the percentage of participants who have best overall response (BOR) of complete response (CR) or partial response (PR) at the time of data cutoff as assessed by RECIST 1.1 and mRECIST | From date of first dose of study drug until disease progression, development of unacceptable toxicity, withdrawal of consent, or sponsor termination (up to 2 years) |

| Disease control rate (DCR) | DCR is defined as the percentage of participants who have best overall response (BOR) of complete response (CR) or partial response (PR) or stable disease (SD) at the time of data cutoff as assessed by RECIST 1.1 and mRECIST. | From date of first dose of study drug until disease progression, stable disease, development of unacceptable toxicity, withdrawal of consent, or sponsor termination (up to 2 years) | 
| Duration of response (DOR) by RECIST 1.1 and mRECIST | DOR is defined as the time from the first documentation of CR or PR to the date of first documentation of disease progression or death (whichever occurs first) as assessed by RECIST 1.1 and mRECIST | From the first documentation of CR or PR to the first date of documentation of disease progression or death whichever occurs first (up to 2 years) | 
| Progression-free survival rate (PFSR) by RECIST 1.1 and mRECIST | PFSR in 6- and 12-months | From date of first dose of study drug to the date of first documentation of disease progression or death, whichever occurs first (up to 2 years) |

| Median overall survival time (mOS) | OS is measured from the start date of the Treatment Phase (date of first study dose) until date of death from any cause. Participants who are lost to follow-up and the participants who are alive at the date of data cutoff will be censored at the date the participant was last known alive or the cut-off date, whichever comes earlier. | From the start date of the Treatment Phase until date of death from any cause (up to 2 years) |
