Active clinical trials for "Neuroendocrine Tumors"

Clinical data from uncontrolled retrospective or prospective studies have initially demonstrated antiproliferative effects of lanreotide in limited number of patients lanreotide Autogel® has recently been approved in more than 40 countries for the treatment of GEP-NET patients, this is based on the results of CLARINET study, the largest prospective trial to evaluate the antiproliferative effects of lanreotide Autogel® in subjects with nonfunctional GEP-NETs. The study enrolled 204 subjects (101 subjects were randomized to lanreotide Autogel® group and 103 subjects were randomized to placebo group, came from 14 countries) with well or moderately differentiated non-functioning GEP-NETs, including pancreatic and gastrointestinal tumors, and defined as having less than 10% of proliferation marker Ki67. The study had shown that treatment with lanreotide Autogel® significantly prolonged progression-free survival in subjects with GEP-NETs compared to treatment with placebo in the primary analysis (median progression-free survival, not reached vs. 18.0 months, P< 0.001 by the stratified log-rank test; hazard ratio for progression or death with lanreotide vs. placebo, 0.47; 95% confidence interval (CI), 0.30 to 0.73) [5]. The indication of GEP-NETs granted for lanreotide Autogel® in the USA is for the treatment of patients with unresectable, well or moderately differentiated, locally advanced or metastatic gastroenteropancreatic neuroendocrine tumors (GEP-NETs) to improve progression-free survival; and in the European Union (EU) is for treatment of grade 1 and a subset of grade 2 (Ki67 index up to 10%) gastroenteropancreatic neuroendocrine tumors of midgut, pancreatic or unknown origin where hindgut sites of origin have been excluded, in adult patients with unresectable locally advanced or metastatic disease. The addition of an indication for the treatment of patients with GEP-NETs has been approved by more than 15 other authorities including in Canada, Australia and some Asian countries, etc.

This is a single-center, single-arm, open-label, phase II trial to evaluate the efficacy and safety of avelumab in subjects with unresectable or metastatic, Grade 2-3, well-differentiated neuroendocrine.tumour.

The study will be conducted to compare the safety and efficacy of Capecitabine Combined With Dacarbazine(CAPDTIC) and Capecitabine Combined Temozolomide(CAPTEM) in advanced or metastatic gastrointestinal pancreatic and esophageal neuroendocrine tumor.In this prospective randomized phase II study, the investigators aim to compare the survival benefit as well as the safety forCapecitabine Combined With Dacarbazine(CAPDTIC) versus Capecitabine Combined Temozolomide(CAPTEM) in advanced or metastatic gastrointestinal pancreatic and esophageal neuroendocrine tumor.

The objective of the PRELUDE study is to describe the use of lanreotide Autogel® (LAN ATG) combined with Peptide Receptor Radionuclide Therapy (PRRT) in the treatment of progressive neuroendocrine tumours located in the lung or in the digestive system as there is currently limited data on these treatments used together for these types of neuroendocrine tumours.

This is a non-randomized phase II , open label, comparative study. Patients with advanced non-resectable and/or progressive gastro-entero-pancreatic Neuroendocrine Tumours - GEP-NET, (G1, G2 and G3), Broncho-pulmonary Carcinoids (BPCs Atypical-AC or Typical-TC), pheochromocytoma/paraganglioma (PPGLs) and neuroendocrine tumours of unknown primary (NET-CUP) with overexpression of somatostatin receptor (SSTR positive) will be enrolled in the study and will be treated using Peptide Receptor Radionuclide Therapy (PRRT) initially with Yttrium-90 (90Y) DOTATATE (DOTA-0-Tyr3-Octreotate), and then compare to Lutecium-177 (177Lu) DOTATATE or mix of both Yttrium-90 (90Y) and Lutecium-177 (177Lu) DOTATATE. Total maximum activity for Yttrium-90 up to 4x3,7GBq, for Lutecium-177 up to 4x5,55GBq (Lu-177) and for both (mix) 4x3,7GBq (90Y and 177Lu 50% each).

Cap-assisted endoscopic mucosal resection (EMR-C) and endoscopic submucosal dissection (ESD) have both been reported to be effective treatment methods for small rectal neuroendocrine tumor (NET) in limited studies. Which one is better has not been determined. We aimed to compare the efficacy and safety of EMR-C and ESD for the treatment of small rectal NET.

AK105 is a humanized monoclonal antibody that specially binds to PD-1. Anlotinib is a small molecule tyrosine kinase inhibitor. Based on the mechanism study, tumor vascular abnormalities promote tissue hypoxia and increase lactic acid, thereby activating immunosuppression and inhibiting T cell function. Anti-angiogenic drugs enhance the infiltration of effector immune cells by inducing normalization of blood vessels and reducing immunosuppression.

This is a phase I study of 177Lu-DOTA-TATE in combination with the PARP-inhibitor olaparib for treatment of patients with somatostatin receptor positive tumours detected by 68Ga-DOTA-TATE/TOC PET. The combination of a PARP inhibitor that will specifically target the repair mechanism, with ionising radiation causing SSB's might overcome the repair dependent survival of the tumour cells, making them more sensitive to β-emission and increase the probability of tumour cell death.

NET originate in neuroendocrine cells throughout the body. The goal of this study is to assess the safety and efficacy of the combination of everolimus and the intravenous radiolabeled Lu-177 DOTATATE Therapy as a 1st line therapy in unresectable well to moderately differentiated metastatic neuroendocrine tumors of all GI, lung and pancreatic origins. This is a phase 1 - 2 study. The phase 1 part involves finding the maximum tolerating dose (MTD) of Everolimus.

The rationale behind the purpose of this study lays on: the evidence that PRRT could represent a valuable treatment for the majority of patients with neuroendocrine tumor (NET) in disease progression, operated or inoperable, presenting lesions expressing somatostatin receptors and for which standard treatments are not already available; the current impossibility of acquiring on the market radiolabelled analogues of somatostatin used for PRRT with marketing authorisation; the need to collect a larger case history than in previous studies; the need to stratify the various histotypes based on the response obtained; the need to define new treatment schemes that guarantee the maximum efficacy and the lowest possible toxicity - with low cumulative (and per cycle) activities radiopharmaceutical and according to the concept of dose hyperfractionation - with a view to an optimal balance between risk and benefit.
