Cryoablation Combined With Anti-PD-1 Antibody in Patients With Advanced Intrahepatic Cholangiocarcinoma

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to evaluate the efficacy and safety of cryoablation combined with anti-pd-1 antibody in patients with advanced hepatocellular carcinoma after progression on first line systemic therapy.

Detailed Description
-----------------
Recent studies have suggested that local destruction of tumor tissue by cryoablation induced activation and maturation of dendritic cells and tumor-specific T cells by cross-presentation of tumor antigens. While pd-1 blocking antibody interferes with PD-1 mediated T-cell regulatory signaling. Therefore, the objective of this study is to evaluate the efficacy and safety of cryoablation combined with anti-pd-1 antibody in patients in advanced intrahepatic cholangiocarcinoma.

Female patients with reproductive potential must have a negative urine or serum pregnancy test within 7 days prior to start of trial. Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment, adherence to contraceptive measures, scheduled visits and examinations including follow up. Exclusion Criteria: History of cardiac disease, including clinically significant gastrointestinal bleeding within 4 weeks prior to start of study treatment Thrombotic or embolic events such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis or pulmonary embolism within the 6 months Prior to the first dose of study drug with the exception of thrombosis of a segmental portal vein. Radiofrequency ablation and resection administered less then 4 weeks prior to study treatment start. Radiotherapy administered less then 4 weeks prior to study treatment start. Major surgery within 4 weeks of starting the study treatment OR subjects who have not recovered from effects of major surgery. Patients with second primary cancer, except adequately treated basal skin cancer or carcinoma in-situ of the cervix. Immunocompromised patients, e.g. patients who are known to be serologically positive for human immunodeficiency virus (HIV). Participation in another clinical study with an investigational product during the last 30 days before inclusion or 7 half-lifes of previously used trial medication, whichever is longer. Any condition or comorbidity that, in the opinion of the investigator, would interfere with evaluation of study Treatment or interpretation of patient safety or study results, including but not limited to: history of interstitial lung disease Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) coinfection (i.e double infection) known acute or chronic pancreatitis active tuberculosis any other active infection (viral, fungal or bacterial) requiring systemic therapy history of allogeneic tissue/solid organ transplant diagnosis of immunodeficiency or patient is receiving chronic systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of nivolumab-monotherapy treatment. Has an active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents. Exceptions: Subjects with vitiligo, hypothyroidism, diabetes mellitus type I or resolved childhood asthma/atopy are an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with Hashimoto thyroiditis, hypothyroidism stable on hormone replacement or psoriasis not requiring treatment are not excluded from the study. Live vaccine within 30 days prior to the first dose of nivolumab-monotherapy treatment or during study treatment. History or clinical evidence of Central Nervous System (CNS) metastases Exceptions are: Subjects who have completed local therapy and who meet both of the following criteria: I. are asymptomatic and II. have no requirement for steroids 6 weeks prior to start of nivolumab-monotherapy treatment. Screening with CNS imaging (CT or MRI) is required only if clinically indicated or if the subject has a history of CNS. Medication that is known to interfere with any of the agents applied in the trial. Any other efficacious cancer treatment except protocol specified treatment at study start. Patient has received any other investigational product within 28 days of study entry. Prior therapy with an anti-Programmed cell death protein 1 (anti-PD-1), anti-PD-L1, anti-Programmed cell death-ligand 2 (anti-PD-L2), anti-CD137 (4-1BB ligand, a member of the Tumor Necrosis Factor Receptor (TNFR) family), or anti-Cytotoxic T-lymphocyte-associated antigen-4 (anti-CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways). Female subjects who are pregnant, breast-feeding or male/female patients of reproductive potential who are not employing an effective method of birth control (failure rate of less than 1% per year). [Acceptable methods of contraception are: implants, injectable contraceptives, combined oral contraceptives, intrauterine pessars (only hormonal devices), sexual abstinence or vasectomy of the partner]. Women of childbearing potential must have a negative pregnancy test (serum β-HCG) at screening. Patient with any significant history of non-compliance to medical regimens or with inability to grant reliable informed consent.
