Cryoablation Combined With Anlotinib Plus TQB2868 in Patients With Advanced Intrahepatic Cholangiocarcinoma

Two cohorts will be recruited. Cohort A will recruit advanced ICC who have progressed after GemCis plus PD1/PD-L1 inhibitor. Cohort B will recruit advanced ICC who have progressed after GemCis plus PD1/PD-L1 inhibitor and anti-vascular endothelial growth factor antibody/tyrosine kinase inhibitors. Both cohorts will receive cryoablation combined with Anlotinib plus TQB2868.

• Anlotinib (Drug): Anlotinib will be administered 10 mg orally daily for 2 weeks followed by a 1 week untreated recovery phase until documented disease progression, development of unacceptable toxicity, participant request, or withdrawal of consent.
• TQB2868 Injection (Drug): TQB2868 will be administered by IV, 300mg on day 1 of each 21 day cycle until documented disease progression, development of unacceptable toxicity, participant request, or withdrawal of consent.
• cryoablation (Procedure): Cryoablation will be performed with a two-cycle freeze-thaw phase protocol; US or non-contrast CT images will be obtained to visualize the evolving ablation zone. Anlotinib plus TQB2868 will be administered 1-3 days after cryoablation.

Primary outcomes

• Objective Response Rate (ORR) [max 24 months]: ORR is defined as the percentage of participants who have a confirmed complete response (CR: disappearance of all target lesions) or partial response (PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters). Responses are according to RECIST 1.1 as assessed by investigator.

Secondary outcomes

• Disease control rate (DCR) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 [max 24 months]: DCR is defined as the proportion of patients with complete response (CR), partial response (PR) and stable disease (SD).
• Duration of Response (DOR) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 [max 24 months]: DOR is defined as the time from first documented complete or partial response until disease progression, death from any cause, or censoring at date of last tumor assessment.
• Time to Response (TTR) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 [max 24 months]: TTR is defined as the time from the start of treatment until the first objective observation of a response (either partial response, PR, or complete response, CR), provided that the response is subsequently confirmed.
• Progression Free Survival (PFS) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 [max 24 months]: PFS is defined as the time from study treatment to disease progression or all-cause death as assessed by the investigator (whichever occurs first)
• Overall survival (OS) evaluated by the investigator per Response Evaluation Criteria in Solid Tumors Version 1.1 [max 42 months]: OS is defined as the time from study treatment to the date of death of the subject, regardless of the cause of death.
• Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 [max 42 months]: An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who experience at least one AE will be reported.
• Translational study [max 42 months]: Proportion of different immune cell types in tumors based on single-cell RNA sequencing between responders and non-responders.
