Cholangiocarcinoma (CCA), cancer of the bile duct, is the first cause of cancer death of the people in the northeast of Thailand. The incidence of CCA in this region is highest not only in the country but in the world. CCA is a slow growing but highly metastatic tumor. At present, there is no standard chemotherapy or effective treatment for CCA. Most of the patients have short survival after diagnosis. Strong evidences from in vitro, animal and clinical studies indicate that vitamin D can prevent and control growth of cancer. Our preclinical studies in CCA cell lines, animal and patient tissue culture indicate that vitamin D effectively reduce growth of CCA. Supplementation of vitamin D to chemotherapeutic drugs enhance drug toxicity and better response. At present, there are several clinical trials in USA on supplementation of vitamin D or its analogs to cancer patients. The side effect or toxicity of using vitamin D supplementation is low, some patients had stable disease and some had good response. The current study is set up a clinical trial phase II of vitamin D (calcitriol) in combination with 5-fluorouracil, Mitomycin C and Leucovorin in an open label-non-randomized study to evaluate the tumor response in patients with advanced intrahepatic cholangiocarcinoma. This study will provide an alternative/effective chemotherapy treatment for CCA patients. Better survival and improved quality of life are also expected.
To assess the proposed therapy for patients with advanced gallbladder or biliary cancers.
OBJECTIVES: This study proposes to evaluate the feasibility of delivery of this treatment in terms of toxicity. If toxicity is not acceptable, the treatment is not feasible. Primary Objectives - To establish a preliminary assessment whether toxicity rates are acceptable in patients with locally advanced intra or extrahepatic cholangiocarcinoma when treated with a regimen of gemcitabine every two weeks and continuous fluorouracil (5-FU) given concurrently with external beam radiation therapy to a total dose of 45 gray(Gy), followed by a brachytherapy or Stereotactic Body Radiation Therapy(SBRT) boost. Secondary Objectives - To evaluate the overall survival rate, progression free survival rate, tumor response rate, local control rate and the rate of distant metastases following gemcitabine and continuous 5-FU concurrent with radiation therapy in patients with locally advanced intra or extrahepatic cholangiocarcinoma. - To evaluate the rate at which patients with unresectable extrahepatic cholangiocarcinoma become resectable following gemcitabine and radiation therapy.
In this study the investigators will be studying the effects of proton beam radiation therapy. This is a very accurate kind of treatment that has been shown to affect less normal tissue than a photon radiation beam. The accuracy allows the investigators to more safely increase the amount of radiation delivered to eliminate cancer. This accuracy will potentially reduce side effects that participants would normally experience using photon radiation therapy. The purpose of this study is to determine if radiation using proton beam therapy will kill the cancer cells in the participants liver.
The aim of this study is to evaluate the safety of Vascular Targeted Photodynamic therapy with WST11 in patients with non-resectable or inoperable biliary carcinoma.
This is a clinical trial investigating the effectiveness and safety of the study drug RAD001 in patients with advanced (metastatic) cholangiocarcinoma. Palliative chemotherapy provides some benefit to this group of patients. However, chemotherapy treatment only shows low rates of radiological response and short times to tumour progression. Therefore, further treatment options are urgently required. In laboratory studies, RAD001 has been shown to interrupt the signals that cancer cells use to grow, spread and form new blood vessels (angiogenesis). RAD001 has been approved for the treatment of kidney cancer. It has also been approved for use in Australia for the treatment of patients with kidney and liver transplants, and has been used in thousands of patients worldwide for this indication. Preliminary studies suggest that RAD001 may have activity in a range of other cancers. This study will evaluate the activity of RAD001 in advanced cholangiocarcinoma.
This is a research study in 2 parts assessing the following parameters of the combination of the study drug called bosutinib, and a drug called capecitabine: the safety, how well the subject's body handles the study drug, and preliminary anti-tumor activity as treatment for different types of cancers in part 1, and breast cancer only in part 2. In part 1, subjects will receive bosutinib and capecitabine daily at different dose levels of each drug in order to determine the highest tolerated dose of the combination study treatment. In part 2, subjects will receive bosutinib and capecitabine at this highest tolerated dose to see how well the study treatment works to treat breast cancer. In addition, genetic research testing (research analyses involving genes and gene products) will be performed on biological samples from subjects.
The purpose of this study is to build on the efficacy of the GEMOX regimen by adding Sorafenib in the treatment of Biliary Tract Cancer. Since there is no data on the combination of these three agents, the investigators plan to evaluate the safety in a run-in phase I portion in order to define the recommended phase II dose (RPTD). The phase II trial will enroll 40 patients at the RPTD level within 2 years in order to provide a preliminary estimate of progression-free survival (primary endpoint of the trial) in the target population.
Primary sclerosing cholangitis (PSC) is a chronic inflammatory condition of the bile ducts of unknown etiology. It is characterized by diffuse inflammation and stricturing of the entire biliary tree, eventually resulting in cirrhosis of the liver. Patients with PSC are at increased risk for the development of cholangiocarcinoma (CCA), a cancer arising from bile duct epithelium. This risk is estimated to be approximately 1 to 1.5% per year. It is postulated that chronic inflammatory changes in the biliary epithelium promote CCA formation. The prognosis of CCA is fatal. The only potentially curative therapy is surgical; however, only a minority of patients qualify for surgical treatment. Several studies have demonstrated overexpression of the epidermal growth factor receptor (EGFR) in CCA cells. EGFR is a type 1 tyrosine kinase promoting cell proliferation, migration and altered cell adhesion - typical characteristics of malignant neoplasias. In CCA cells, EGFR-activation is sustained resulting in cancer progression. In human CCA samples, EGFR-expression correlates with higher histologic grade, poor prognosis, and risk of recurrence. The EGFR gene is located on the short arm of chromosome 7 (7p12). Chromosomal abnormalities of the bile duct epithelium, particularly trisomy 7 (i.e. three copies of chromosome 7) can be detected in biliary epithelial samples obtained by endoscopic retrograde cholangiopancreatography (ERCP) in PSC patients. The finding of cells with trisomy 7 has preceded the development of aneuploidy and multiple chromosomal abnormalities in a number of patients, the latter chromosomal abnormalities are characteristic of CCA. Trisomy 7 amplifies the gene for EGFR thereby presumably promoting overexpression of this growth factor receptor. In a cohort of patients with Trisomy 7 and Primary Sclerosing Cholangitis patients followed for 1 year, the rate of development of Cholangiocarcinoma was 35% (n=37, Dr. Gores, unpublished observation). Patients without cytologic abnormalities were at minimal risk for the development of CCA. Erlotinib (Tarceva) is a human EGFR type 1 tyrosine kinase inhibitor. Tarceva received FDA approval as single agent treatment for patients with locally advanced or metastatic non-small cell lung cancer. In a randomized, double blind, placebo controlled trial of 731 patients, receiving 150 mg of Tarceva or placebo once daily, median survival was prolonged to 6.7 months from 4.7 months (p<0.001). Analysis of epidermal growth factor receptor expression (45% of total study patients) demonstrated greater survival benefit in EGFR positive patients. Tarceva in combination with Gemcitabine is also FDA approved as first line therapy in patients with locally advanced, unresectable or metastatic pancreatic cancer. Our central hypothesis is that patients with trisomy 7 will have carcinogenic changes including EGFR overexpression. EGFR blockade will inhibit a growth/survival advantage for these premalignant clones eliminating them from the biliary epithelium. As an initial step towards testing this hypothesis, the tolerability of Tarceva in this patient population needs to be established. This study will assist in determining the safety and tolerability of Tarceva in patients with primary sclerosing cholangitis. This study will be followed by a Phase 2 randomized controlled trial of Tarceva in patients with Primary Sclerosing Cholangitis with Trisomy 7.
