Filter by:This multicenter, non-randomized, Phase II study will assess the efficacy, safety, and pharmacokinetics of trastuzumab emtansine in participants with HER2 overexpressing locally advanced (unresectable and not treatable with curative intent) or metastatic urothelial bladder cancer (UBC), locally advanced (unresectable and not treatable with curative intent) or metastatic pancreatic cancer/cholangiocarcinoma with advanced disease where cure is no longer possible and where no other treatment options are available anymore. Participants will receive intravenous (IV) infusion of trastuzumab emtansine as Regimen A (2.4 milligrams per kilogram [mg/kg], weekly [qw]) or Regimen B (3.6 mg/kg, every 3 weeks [q3w]) until unacceptable toxicity, withdrawal of consent, disease progression (PD), or death, whichever occurs first. Based on tolerability and safety aspects, steering committee and Independent Data Monitoring Committee (iDMC) will decide on expansion of the study to include more participants with other carcinoma types.
Shear Wave Elastography (SWE™) is a quantitative elastography method for measuring tissue stiffness. The difference in stiffness between benign and malignant tumors has been demonstrated by other elastography methods (acoustic radiation force impulse imaging, transient elastography and/or magnetic resonance elastography). The investigators hypothesized that benign liver tumors are softer than malignant liver tumors measured by SWE™, allowing differentiation between the two by tumor stiffness expressed in kilopascal (kPa). In this study benign and malignant liver tumors will be evaluated in five groups: 1) hemangioma and 2) focal nodular hyperplasia (FNH) representing the most common benign liver tumors; 3) metastases and 4) cholangiocarcinoma (CCC), both presenting malignant tumors mostly appearing in otherwise healthy liver, and 5) hepatocellular carcinoma (HCC) mostly occurring in cirrhotic liver, which can potentially influence elastographic measurements therefore querying the appropriateness of comparison between tumors in healthy and cirrhotic liver. Enrolled patients will undergo transabdominal ultrasonography and SWE™ examination. The tumor stiffness will be measured five times for each tumor. Additionally, surrounding liver parenchyma stiffness will be measured. The nature of the liver tumor will be defined through a standard diagnostic workup according to current guidelines, including contrast enhanced multi-slice CT, MRI and/or cytology/histology, as applicable. In the final analysis the mean tumor stiffness and tumor-parenchyma ratio will be calculated for each group as well as for benign and malignant tumors separately, and cut-off values for the differentiation of various groups will be derived. The clinical value of the method will be appraised based on specificity, sensitivity, positive and negative predictive values, and AUC.
An open label, prospective, non-randomized single arm study. Combination of two treatment modalities - HAI with FUDR and systemic chemotherapy with cisplatin and gemcitabine. Definition of the maximum tolerated dose (MTD) of intravenous gemcitabine in combination with intravenous cisplatin and intra-arterial FUDR. Definition of safety and toxicity of this combined regional and systemic treatment approach. Definition of the response rate after 3 months of hepatic intra-arterial chemotherapy with continuous infusion FUDR with or without ligation of the right or left portal vein, in combination with 3 months of systemic cisplatin and gemcitabine in patients with unresectable intrahepatic or hilar CCC. A total of 9-18 patients are required. 3-6 patients per dose level. A maximum of three dose levels (1 - 3) has been defined. Statistical Methodology: Traditional 3+3 dosing algorithm to find MTD. - Trial with medicinal product
Malignant biliary obstruction is a common clinical condition caused by various malignancies. Currently,biliary stent implantation guided either by fluoroscopy or endoscopy has become the most important methods for relieving malignant biliary obstruction. However, the benefit for the survival of the patients with palliation of the stent treatment is limited because no therapeutic effects on process of the tumor itself by a stent implantation. Encouraged by the success of 125I esophageal stent in esophageal carcinoma, a novel biliary stent loaded with 125I radioactive seeds has been developed in our institute. After ex vivo and in vivo evaluations for the delivery system, the investigators prospectively compare the responses to treatment with this radiation biliary stent, versus the conventional biliary SEMS in patient with malignant biliary obstruction.
OBJECTIVES Primary objective: The primary objective of the trial is to determine the safety of adjuvant treatment with cisplatin plus gemcitabine for a period of 6 months after curative resection of cholangiocellular carcinoma Secondary objectives: Secondary objectives of the trial are to assess the feasibility and efficacy of the adjuvant therapy and to determine duration of response and patterns of failure compared to historical controls without postoperative treatment Exploratory objectives: To obtain blood samples and tumor tissue after resection for establishment and characterization of new cholangiocarcinoma cell lines and tumor antigens. Other aims are identification of tumor specific antibodies from blood samples, and characterization of tumor antigens with consecutive development of new specific immunological therapies, e.g. cancer-testis antigens (CTA) for tumor vaccination. - Trial with medicinal product
