Active clinical trials for "Pancreatic Neoplasms"

Pancreatic Cancer is a leading cause of cancer-related death. To date, only one fifth of patients at diagnosis is presented resectable because the diagnosis is often delayed making the 5-year survival of this disease globally less than 5%. An early diagnosis in these patients is currently not possible given the economic disadvantages of a population-wide screening. New evidences identify patients with new-onset diabetes as a subgroup of patients at high risk of developing this disease (RR 5:38). In a subset of these patients a mediator secreted by the tumor, the Adrenomedullin, could be responsible for the onset of diabetes. Our goal is therefore to assess the different impact of Pancreatic Cancer depending on Adrenomedullin values in patients with newly diagnosed diabetes mellitus.

The study is based on a multi-center approach of needle based confocal laser endomicroscopy (nCLE) combined with endoscopic ultrasound (EUS) and EUS-guided fine needle aspiration (FNA) to evaluate pancreatic cystic lesions (PCL), in order to obtain a correct histopathological diagnosis.After detection of PCL, certain morphological EUS features allow the discrimination of specific cyst types. Additionally, EUS-FNA is recommended as the first-line procedure whenever pathological diagnosis is required; however the procedure has its drawbacks, mainly represented by the relatively low negative predictive value in diagnosing pancreatic cancer. In this case a more precisely diagnostic tool is required; the potential role of CLE has been explored in gastrointestinal (GI) pathology showing good accuracy for predicting the final histopathological diagnosis based on immediate evaluation of tissue and vascular patterns. Although the clinical impact of nCLE for the decision making algorithms in cystic pancreatic neoplasm has not yet been described, the hypothesis is that EUS-nCLE could allow targeted tissue sampling of cystic pancreatic neoplasms resulting in more accurate diagnosis. The aim of the study is to describe the clinical impact of nCLE for the clinical decision management algorithm based on EUS, EUS-FNA and/or EUS-CLE imaging criteria for cystic pancreatic neoplasms, while evaluating also the feasibility and safety of nCLE examination.

This Endoscopic Ultrasound guided Biliary Drainage (EUS-BD) vs. Endoscopic Retrograde Cholangiopancreatography (ERCP-TP) trial (BILPAL) is a randomized controlled multicenter trial that will provide evidence whether or not traditional ERCP biliary drainage is to be performed in patients with obstruction in bile duct due to unresectable pancreatic head or periampullary tumor.

Pancreatic carcinoma typically has a high recurrence rate and very poor prognosis. Surgery is the best choice for the treatment of pancreatic cancer, but for those advanced pancreatic cancer patients，when surgery is not available，chemotherapy combined with radiation therapy or interventional therapy is commonly used in the treatment，but the prolonging survival effect is not obvious. And now, some clinical researchers use CAR-T cells in the treatment of pancreatic carcinoma, according to the existing results, therapeutic effects are not as good as expecting. One of the most likely reasons is that they continued to use the intravenous infusing of CART cells to patients, when the T cells into the blood circulation, will result in decreased tumor activity and more potential adverse effects. We believe that a suitable TAA targeted-CAR-T cells will be an effective way to treat cancer, as long as the pathway of the cell infused to the body can not only improve the drug concentration of the tumor site but reduce the potential off-target side effects. In order to achieve this goal, it is probably the best choice to use vascular intervention to mediate CAR-T cells infusion. Mesothelin is a cell-surface antigen implicated in tumor invasion, which is highly expressed in pancreatic carcinoma but low-level expressed in mesothelia. We design a 2nd CART cells targeted with mesothelin, and use vascular intervention mediated CAR-T infusion to patients. We hope deliver anti-mesothelin CART cells locally can reducing the side effects while enhancing the antitumor affect by more CART cells accumulate in tumor sites while less can reach normal mesothelial tissue.

Pancreatic cancer is 5th leading cause of cancer-related death in Korea. It has a dismal prognosis with very low 5-year survival rate, about 5%. Only 10% of pancreatic cancer patients is diagnosed in operable status. So, most of patients could not be treated with curative resection. Locally advanced pancreatic cancer (LAPC) is defined by defined as surgically unresectable due to vascular encasement (e.g. celiac trunk or superior mesenteric artery) by tumor, but have no evidence of distant metastases. In LAPC patients, systemic chemotherapy with/without radiotherapy was used as a standard therapy, but therapeutic response was very poor. Only less than 30% of patients showed treatment response, and median survival of LAPC patient was only 9 months. Thus, more effective treatment modality is needed for LAPC patients. Irreversible electroporation (IRE) is a soft tissue ablation technique using ultra short but strong electrical fields to create permanent and hence lethal nanopores in the cell membrane, to disrupt the cellular homeostasis. IRE does not cause thermally induced necrosis and has tissue selectivity, so adjacent tissue or vascular structures can be preserved. Several clinical trials using IRE were performed to liver, kidney or lung cancer patients. We will operate IRE procedure to LAPC patients who were previously received standard therapy but showed no response, using NanoKnife IRE device. We will investigate treatment response and safety of IRE.

A. Pancreatic cancer background In 2012, 1,172 new pancreatic cancer patients were diagnosed in Switzerland. Only 20% of the patients with newly diagnosed pancreatic cancer are candidates for surgical resection, the only potential treatment for cure. Over 30% of the patients initially present with locally advanced disease. Patients with locally advanced disease have no evidence of metastatic spread to the liver, lung, and peritoneum but present with local involvement of vital structures that prohibits reasonable tumor resection. Currently, those patients are evaluated for palliative chemotherapy +/- radiation therapy. However, even with best conventional medical therapy, median survival of patients with locally advanced disease is mostly below 1 year. Over the last years, loco-regional therapies gained increased attention including radiofrequency-, cryo-, and microwave ablation as well as electrochemotherapy. However, all those entities are criticized by their complication rates leading to morbidity and mortality, limited area of application given the complex anatomical structures around the pancreas, and ill-defined improvements in overall survival. B. Irreversible electroporation (IRE): Irreversible electroporation is an emerging ablative modality that gained enormous interest over the last five years. For locally advanced pancreatic cancer, it was introduced in 2009. IRE is mainly non-thermal and primarily works through apoptosis. Its well studied safety profile allows ablation also within the context of locally advanced pancreatic cancer given it mainly spares vessels from destruction. Increasing evidence shows that IRE for locally advanced, unresectable pancreatic cancer is effective compared to historic controls with a significant prolongation of local progression free survival, distant progression free survival and overall survival. The improvement in overall survival is about double the amount of what is seen with best new chemotherapy and chemoradiation regimens used at the present time. Those results are even more impressive given the discouraging improvements among palliative systemic options. The NanoKnife IRE device (Angiodynamics, Queensbury, NY) is commonly used to perform IRE procedures in pancreatic cancer patients and is commercially available since 2009 and got Food and Drug Administration (FDA) 510K clearance for soft tissue ablation in October 2011 in the United States. C. Quality of life and nutritional status/long term outcomes Given the overall poor long-term outcomes of patients with pancreatic cancer, health-related quality of life (HRQoL) measures are of utmost importance when treatment recommendations are discussed with patients. This is especially true for patients with more advanced staged disease where definitive surgical resection with curative intent is not possible. However, HRQoL reports for patients with locally advanced pancreatic cancer undergoing IRE are very limited. To the best of the investigators' knowledge, no other specific investigations exist that assessed HRQoL measures for patients undergoing IRE for locally advanced pancreatic cancer, no specific assessment exists that focuses on nutritional status for this patient group. In addition, impact on local and distant recurrence as well as cancer-specific and overall survival are still ill-defined and further information is needed.

Registry participants with advanced malignancy or myelodysplasia will have a sample of their tumor or tissue analysed for genetic alterations using next generation sequencing (NGS) performed in a lab that has been certified to meet a high quality standard. Treatments and outcomes will be reported to the registry to allow further understanding of how genetic differences can lead to better diagnosis and treatments.
