Filter by:The purpose of this study is to assess the safety and tolerability of the investigational anticancer drug DCR-MYC. DCR-MYC is a novel synthetic double-stranded RNA in a stable lipid particle suspension that targets the oncogene MYC. MYC oncogene activation is important to the growth of many hematologic and solid tumor malignancies. In this study the Sponsor proposes to study DCR-MYC and its ability to inhibit MYC and thereby inhibit cancer cell growth.
This phase II trial studies how well dovitinib lactate works in treating patients with pancreatic neuroendocrine tumors. Dovitinib lactate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Neuroendocrine tumors (NETs) are neoplasms originating from neuroendocrine cells located throughout the body. They secret various peptides and cause various symptoms (carcinoid syndrome) or not. The incidence of NETs was not well-known till recently when Yao et al. and Hausa et al. published their surveys of NETs using data from the US Surveillance, Epidemiology, and End Results (SEER) program and from the Norwegian Registry of Cancer (NRC). The incidence of NETs in Taiwan by using the Taiwan Cancer Registry (TCR) data was increased from 0.3 to 1.51 per 100,000 from 1996 to 2008. The increased incidence for NET worldwide probably was partially due to the awareness and improvement of diagnostic technology. Compared with the incidence in western countries, the incidence of NET is much lower in Taiwan. And the incidence of NETs in Asian Pacific Islanders was also lower than the whites and blacks in US. Gastroenteral-pancreatic NETs (GEP-NETs), accounting for half to two thirds of all NETs, is the most common site of NETs. As the progress in the understanding of pathophysiology for GEP-NET, there are two novel targeted agents shown to be effective for the treatment of GEP-NET. Meanwhile, response to mTOR inhibitor was better for Asian than Caucasian in the phase III study using everolimus for advanced pancreatic NETs. These information suggests that there is racial difference for either genetic or environmental risk factors and these factors result in different incidence and/or clinical outcome. Currently, there is limited data for thorough epidemiologic study in Taiwan. The aim of this study is to collect clinical information for GEP-NET, and survey the prognostic factors for GEP-NET in Taiwan. the investigators suppose that this epidemiologic study would provide a database potentially to improve the diagnosis, and treatment of GEP-NET. This study plans to include 600 GEP-NET patients. NET patients diagnosed after 2011.1.1 is included in this study. Furthermore, the investigators will provide the check of immunohistochemical staining for the tumor tissue of GEP-NET patients, including the functioning status (insulinoma, glucagonoma, gastrinoma, VIPoma) and the degree of differentiation, the expression of SSTR2 or SSTR5 and the check of possible primary site for unknown primary NET patients. This examination will provide more accurate diagnosis for the patients and further treatment suggestion for the patients.
This phase II trial studies ziv-aflibercept in treating and perfusion computed tomography perfusion imaging in predicting response in patients with pancreatic neuroendocrine tumors that have spread to other parts of the body or cannot be removed by surgery. Ziv-aflibercept may stop the growth of tumor cells by blocking blood flow to the tumor. Diagnostic procedures, such as computed tomography perfusion, imaging may help measure a patient's response to ziv-aflibercept treatment.
This pilot research trial studies molecular analysis in tissue samples from patients with advanced or metastatic neuroendocrine tumors. Studying samples of tissue from patients with neuroendocrine tumors in the lab may help doctors identify mutations to classify disease and plan the best treatment.
The purpose of this study is to determine the use of 177Lu-PP-F11N for imaging and therapy of patients with advanced medullary thyroid carcinoma (MTC). 177Lu-PP-F11N is a gastrin analogon, binding to cholecystokinin-2 receptors. This receptors show an overexpression on more than 90 % of medullary thyroid carcinomas. In the pilot (phase 0) study investigators will correlate the tumour detection rate with the surgery and histology (proof of concept study). Furthermore, kidney protection and dosimetry studies will be performed in order to determine the kidney protection protocol and starting activity for the dose escalation study in the following, dose escalation (phase I) study. In the phase I study investigators will determinate the maximum tolerated dose of 177Lu-PP-F11N in patients with MTC. Furthermore, correlation with tumour radiation dose and treatment response as well as organ radiation doses and maximal tolerated dose will be performed in order to allow prospective individual patient tailored therapy planning. In the phase I study, participation is additionally possible for patients with well differentiated GEP-NET (grade 1-3) with a Ki67 index of up to 55% or NET of the lung or thymus (grade 1 and 2).
The investigators hypothesize that the new imaging method Gallium-68-DOTATATE has a higher diagnostic value in the detection of neuroendocrine tumors than the established imaging method Indium-111-Octreoscan. Therefore, the investigators will perform both imaging procedures in patients with suspected or confirmed neuroendocrine tumors. Subsequently, the investigators will compare the diagnostic performance of both methods.
Dose escalation part: to determine the highest dose of alpelisib administered on a daily basis when given in combination with daily everolimus or in combination with daily everolimus and exemestane. Dose expansion part: To describe safety and tolerability of the alpelisib and everolimus or alpelisib, everolimus and exemestane combinations.
Circulating tumour cells (CTCs) are detectable in the blood in around 50% of patients with functioning NeuroEndocrine Tumours (NET) arising in the midgut area (tumours which are secreting hormones and are located in the area in the middle of the digestive system) and their presence usually means that the prognosis for the patient is poor. CTCs have also been shown to be valuable as predictive markers following treatment and there is increasing interest in using CTCs as 'liquid biopsies' that can help to inform treatment decisions. CTC analysis has the benefit of being relatively non- invasive and quick compared with a conventional CT scan and is therefore an attractive method of monitoring the tumour throughout the treatment period. The purpose of this study is to assess the clinical value that enumeration will have in predicting the clinical symptomatic response and progression free survival in patients receiving Somatuline Autogel for functioning midgut NETs over a one year period.
Patients with gastroenteropancreatic neuroendocrine tumours (NET) often die from intrahepatic disease or are excluded from liver-directed treatment because of extrahepatic disease. Adjuvant liver-directed treatment is warranted to control both intra- and extrahepatic disease. Patients with liver metastases of NET will be included in this study (n = 30-48).The efficacy and toxicity of adjuvant 166Ho-radioembolization (166Ho-RE) after systemic 177Lu-dotatate will be studied in a non-comparative phase II study. The study is an interventional, treatment, non-randomized, open label, non-comparative, phase II study. 166Ho-RE will be performed via a catheter during angiography.
