Active clinical trials for "Biliary Tract Neoplasms"

The purpose of this study is to evaluate the efficacy and safety of mFOLFOX (5-fluorouracil, leucovorin, oxaliplatin)as salvage therapy in patients with unresectable biliary tract cancer who had failed gemcitabine.

Obstruction of the digestive tract is a frequent cause of morbidity in patients with gastrointestinal cancer.Palliative endoscopic treatment with self- expanding metal stents(SEMS)is an alternative to palliative surgery and other palliative treatment options.The method has expanded to include patients with malignancies in the esophagus,gastroduodenal region, biliary tractus and colon. Numerous retrospective studies have reported treatment with SEMS to be safe and effective. Prospective studies,and especially studies regarding Quality of Life improvement are needed. PURPOSE: The purpose of this trial is to prospectively study the use and effect of selfexpanding metal stents(SEMS)in a defined population i Norway, especially Quality of Life changes.

The main purpose of this study is to test the safety and effectiveness of oxaliplatin, bevacizumab, and capecitabine given in combination with radiation therapy to see what effects (good or bad) they have on patients with biliary tract and gallbladder cancer.

To validate the superiority of Gemcitabine/Cisplatin/S-1 over Gemcitabine/Cisplatin for unresectable biliary tract cancer.

This is a multicenter, single arm, open-label study in participants with unresectable BTC and disease progression or failure following one prior gemcitabine-based doublet chemotherapy regimen (combination of gemcitabine and cisplatin, or gemcitabine and other platinum agent/fluoropyrimidine agent). This study contains 3 phases: a Pre-treatment phase that will last within 21 days; a Treatment phase that will consist of study treatment cycles and tumor assessment conducted every 6-8 weeks; and a Follow-up phase that will begin immediately after the Off-Treatment Visit and will continue as long as the participant is alive, unless the participant withdraws consent, or until the End of Study.

Biliary tract cancer is relatively rare cancer, with generally poor prognosis. In metastatic/recurrent biliary tract cancer, the most commonly used 1st-line chemotherapy is gemcitabine+cisplatin combination. However, there is no standard 2nd-line chemotherapy and there is no validated targeted therapeutic agent, even though this tumor harbors diverse genetic characteristics. TH-302 (1-methyl-2-nitro-1H-imidazole-5-yl)methyl N,N'-bis(2-bromoethyl) diamidophos-phate is a nitroimidazole-linked prodrug of a brominated version of isophosphoramide mustard (Br-IPM). When exposed to hypoxic conditions, TH-302 is reduced at the nitroimadazole site of the prodrug by intracellular reductases leading to the release of Br-IPM. Br-IPM can then act as a DNA crosslinking agent. In areas of normoxia, TH-302 remains intact as a prodrug and toxicity is minimized. In addition, preclinical data suggest that after activation, the active moiety may diffuse to areas outside the hypoxic region, demonstrating a "bystander" effect and possibly exhibiting additional anti-tumor activity. It is well known that biliary tract cancer is hypovascular tumor, so it contains large hypoxic area in the tumor. Therefore it would be worthy to test TH-302 in biliary tract cancer. This study is a phase II study of TH-302 monotherapy as second-line treatment in advanced biliary tract cancer, to investigate efficacy and safety of TH-302 monotherapy.

Biliary obstruction is importantly influencing quality of life and survival of patients suffering from primary or secondary bile duct malignancies. The aim of this retrospective data analysis is to evaluate endoscopic radiofrequency ablation (RFA) with the HabibTM EndoHBP catheter for the treatment of malignant biliary obstruction. RFA procedures performed in Austria so far will be analyzed with regard to feasibility and safety of the technique. Therefore, the following parameters will be assessed: (among others) technical failures during the RFA procedure, complications during the RFA procedure, hospital stay, adverse events during hospital stay and until first clinical control after discharge (an expected average of 4 weeks after RFA procedure), 30-day and 90-day mortality. The results of this study should help to better understand important aspects of biliary RFA which may positively influence future applications of this method.

To compare efficacy and safety of Gemcitabine versus S-1 adjuvant therapy after hemihepatectomy.

This study will conduct a phase II study of gemcitabine and S-1 as first-line chemotherapy in patient with advanced biliary tract cancer

Primary Objective: To evaluate disease control rate (DCR) of S-1 in combination with gemcitabine in patients with advanced biliary tract cancer Secondary Objectives: To evaluate overall response rate (ORR) To evaluate progression-free survival (PFS) To evaluate overall survival (OS) To assess the safety profile
