Active clinical trials for "Adenoma, Islet Cell"

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of PS-341 in treating patients who have metastatic neuroendocrine tumors.

Adjuvant therapy in pancreatic neuroendocrine tumors (pNETs) after radical resection lacks evidence-based data and is controversial. Real-world data were clustered to validate whether the long-acting octreotide is a potential candidate for adjuvant therapy in high recurrence risk G2 pNET patients.

This phase I trial studies the side effects and best dose of veliparib when given together with capecitabine and temozolomide in treating patients with neuroendocrine tumor that has spread to other places in the body and usually cannot be cured or controlled with treatment, has returned after a period of improvement, and cannot be removed by surgery. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as capecitabine and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

Everolimus represents an approved therapy for patients with advanced well/moderately differentiated pancreatic NETs. Although some patients could benefit from this drug in terms of long-term tumor growth control, others are resistant upfront or become resistant during treatment. Therefore, it is crucial to detect some biological factors which can help to identify the responsive tumors. Given that Everolimus is a biological agent and its mechanism of action can be partially directed towards angiogenesis its effects can be studied on different levels and with different methods. Upfront and early surrogate predictive markers of activity/efficacy can be studied on tumor tissue, tumor imaging, and peripheral blood. mTOR pathways alterations, circulating endothelial cells, and other circulating angoigenic factors will be correlated with clinical outcome. Tumor perfusion and circulating markers will be studied also as markers of response compared with the morphological imaging.

The purpose of this study is to confirm the safety and efficacy of sunitinib in subjects with unresectable pancreatic neuroendocrine tumors.

A Phase II Randomized,Controlled,Open Label,Multicentre Study to evaluate the efficacy and safety of Tegafur combined with Temozolomide versus Tegafur combined with Temozolomide and Thalidomide in subjects with Advanced Pancreatic Neuroendocrine Tumor

This is a randomized phase II, parallel group study. Patients with gastro-entero-pancreatic neuroendocrine tumors (GEP-NET) well differentiated G1 - G2 (ki67≤ 20%) and G3 (ki67≤ 50%), somatostatin receptor (SSR) positive and 18-FDG positive will be enrolled in the study and will be randomly assigned to 2 different arms: Arm Lu-PRRT-Cap: oral low dose of capecitabine in association with Lu-PRRT (at 3.7 Gbq per cycle x 7 cycles) followed by long acting octreotide or lanreotide (SS-LAR); OR Arm Lu-PRRT: Lu-PRRT (at 3.7 gigabecquerel (Gbq) per cycle x 7 cycles) followed by SS-LAR.

The primary objectives are: Dose escalation: 1. To determine the MTD and DLT(s) of TH-302 when used in combination with sunitinib. Dose expansion: To make a preliminary assessment of the efficacy of TH-302 in combination with sunitinib as determined by the response rate and the progression-free survival in subjects with advanced RCC treated at the RP2D To assess the safety of TH-302 in combination with sunitinib and determine a recommended Phase 2 dose of the combination. The secondary objectives are: Dose expansion: 1. To make a preliminary assessment of the efficacy of TH-302 in combination with sunitinib as determined by stable disease or better rate, duration of response and overall survival in subjects with advanced RCC treated at the RP2D. The exploratory objective is: 1. To explore the association of serum hypoxia biomarkers with efficacy endpoints.

The purpose of the protocol is to estimate the progression-free survival (PFS) rate in subjects diagnosed with PanNET, according to investigator assessment, at 24 months after treatment initiation with lanreotide 120 mg every 28 days.

The aim of this phase I-II study is to evaluate the efficacy and toxicity of PRRT with 177Lu-DOTATATE (Lu-PRRT) associated to metronomic chemotherapy with Capecitabine in patients affected by aggressive FDG-positive gastro-entero-pancreatic NET. Moreover to analyze the effects of the capecitabine metronomic schedule on the level of circulating angiogenetic factors.
