Active clinical trials for "Adenoma, Islet Cell"

This phase II trial studies the effect of capecitabine and temozolomide after surgery in treating patients with high-risk well-differentiated pancreatic neuroendocrine tumors. Chemotherapy drugs, 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. Giving capecitabine and temozolomide after surgery could prevent or delay the return of cancer in patients with high-risk well-differentiated pancreatic neuroendocrine tumors.

The present study aims to evaluate the feasibility, safety and efficacy of EUS-FNI for MEN1-related pNETs

This phase I trial tests the safety, side effects, and best dose of sunitinib malate in combination with lutetium Lu 177 dotatate in treating patients with pancreatic neuroendocrine tumors. Sunitinib malate is in a class of medications called kinase inhibitors and a form of targeted therapy that blocks the action of abnormal proteins called VEGFRs that signal tumor cells to multiply. This helps stop or slow the spread of tumor cells. Radioactive drugs, such as lutetium Lu 177 dotatate, may carry radiation directly to tumor cells and not harm normal cells. It is also a form of targeted therapy because it works by attaching itself to specific molecules (receptors) on the surface of tumor cells, known as somatostatin receptors, so that radiation can be delivered directly to the tumor cells and kill them. Giving sunitinib malate and lutetium Lu 177 dotatate in combination may be safer and more effective in treating pancreatic neuroendocrine tumors than giving either drug alone.

The current study aims to access the feasibility, safety, and efficacy of EUS-FNI for nonfunctional pNETs

A Phase 2 multi-center, open-label, single arm study of nab-sirolimus in patients with well-differentiated neuroendocrine tumors (NETs) of the gastrointestinal tract, lung, or pancreas who have not received prior treatment with mTOR inhibitors

This is a study to evaluate the efficacy and safety of belzutifan monotherapy in participants with advanced pheochromocytoma/paraganglioma (PPGL), pancreatic neuroendocrine tumor (pNET), von Hippel-Lindau (VHL) Disease-Associated Tumors, Advanced Gastrointestinal Stromal Tumor (wt GIST), or Advanced Solid Tumors With hypoxia inducible factor-2 alpha (HIF-2α) related genetic alterations. The primary objective of the study is to evaluate the objective response rate (ORR) of belzutifan per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).

Doctors and researchers leading this study hope to learn more about peptide receptor radionuclide therapy (PRRT) in combination with cytoreduction (surgically removing tumors). They hope to learn if combining PRRT in combination with cytoreduction would be more effective than cytoreduction alone. PRRT itself is approved by the U.S. Food and Drug Administration (FDA) for people with PanNETs however the combination with cytoreduction is considered experimental. Your participation in this research will last about 2 years. The purpose of this research is to gather information on the safety and effectiveness of PRRT.

This phase II trial compares capecitabine and temozolomide to lutetium Lu 177 dotatate for the treatment of pancreatic neuroendocrine tumors that have spread to other parts of the body (advanced) or are not able to be removed by surgery (unresectable). Chemotherapy drugs, 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. Radioactive drugs, such as lutetium Lu 177 dotatate, may carry radiation directly to tumor cells and may reduce harm to normal cells. The purpose of this study is to find out whether capecitabine and temozolomide or lutetium Lu 177 dotatate may kill more tumor cells in patients with advanced pancreatic neuroendocrine tumors.

Neuroendocrine tumors (NETs) are relatively rare tumors, mainly originating from the digestive system, that tend to be slow growing and are often diagnosed when metastatic. Surgery is the sole curative option, but is feasible only in a minority of patients. Peptide Receptor Radionuclide Therapy (PRRT) has been experimented for almost 20 years and is an established effective therapeutic modality for well/moderately differentiated, inoperable or metastasized gastro-entero-pancreatic (GEP) and bronchial NETs. Clinical studies demonstrated that partial and complete objective responses can be obtained in up to 30% of patients. Side effects may involve the kidneys and the bone marrow and are usually mild. Renal protection is used to minimize the risk of a late decrease of renal function. A new application for P-NETs is preoperative PRRT. Since surgery is the only curative option for GEPNETs, preoperative PRRT could increase the efficacy of surgery. However, this modality has not been fully explored in dedicated studies and there are just few sporadic case reports that described the preoperative use of PRRT in pancreatic NETs who could then be operated on successfully. Moreover there are few experiences demonstrating the advantage of PRRT associated to surgery in a multidisciplinary setting. In addition, the possibility of detecting the circulating NET transcripts by means of transcriptome analysis could represent an early marker of response to PRRT and improve the patient management. Aim of this study is to evaluate the response and rate of R0 surgery in patients with unresectable or borderline resectable PNETs eligible to PRRT with 90Y-DOTATOC and correlate the response to the variation in circulating NET transcripts measured before and after the end of PRRT. It has been recently shown that a PCR-based 51 transcript signature is significantly more sensitive and efficient than single analytes (e.g. CgA) in NET diagnosis and follow up. 30 patients will be enrolled in the study; each of them will receive 1.85 GBq/cycle of 90Y-DOTATOC with a cumulative activity of 9.25-11.1 GBq in 5-6 cycles (depending on personalized dosimetry). Therapy response will be assessed by morphological (CT/MRI) and functional (PET/CT or Octreoscan) imaging after 3 and 6 months from the completion of PRRT and compared with transcript analysis. Based on literature reports we expect a response rate of about 35% of patients.

This phase III trial studies cabozantinib to see how well it works compared with placebo in treating patients with neuroendocrine or carcinoid tumors that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Cabozantinib is a chemotherapy drug known as a tyrosine kinase inhibitor, and it targets specific tyrosine kinase receptors, that when blocked, may slow tumor growth.
