Active clinical trials for "Neuroendocrine Tumors"

The aim of this non-randomised, prospective study is to investigate the applicability and prognostic value of uPAR PET/CT with the radioligand 68Ga-NOTA-AE105 in patients with neuroendocrine tumors (NETs).

This phase II trial studies the effect of retifanlimab and telotristat ethyl in treating patients with neuroendocrine tumors that have spread to other places in the body (advanced) and carcinoid syndrome. Retifanlimab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Telotristat ethyl is a drug used to reduce side effects of carcinoid syndrome. Giving retifanlimab and telotristat ethyl may help to control neuroendocrine tumors in patients who also have carcinoid syndrome.

The main goal of the study is to expand cancer preclinical research results on the usefulness of SSTR2-Antagonist [99mTc]Tc-TECANT1 in clinical practice. Detection of NEN and monitoring of response to therapy is still challenging due to their cellular heterogeneity. Initial preclinical studies suggest that NEN imaging with the use of SSTR2-Antagonist may be advantageous in comparison to the widely used SSTR2-Agonists. Recently, novel radiopharmaceuticals, based on SSTR2-Antagonists, were shown to provide superior SSTR2 visualisation than currently used agonists. The need for molecular imaging of NEN is expected to grow significantly in the near future due to their increasing incidence and prevalence. Although a persistent trend to shift the molecular imaging of NEN from conventional SPECT/CT gamma cameras to PET/CT has been observed in the last decade, labelling the compound with Tc-99m offers significant advantages by its extremely wide availability, low cost and low radiation exposure to patients. Effective and accessible molecular imaging methods as an integral part of personalised patient management are needed to optimise selection and follow-up of available therapeutic modalities. The Tc-99m-labeled SSTR2-Antagonist [99mTc]Tc-TECANT1 is expected to be an effective, widely available compound for quantitative assessment of SSTR2 NEN status, allowing a personalised therapeutic approach.

The purpose of this study is to assess the safety and tolerability of 68Ga-OPS202 used for the diagnosis of gastroenteropancreatic neuroendocrine tumors (GEP NETs).

This protocol is designed to test the efficacy of 68Ga-DOTATOC PET/CT in diagnosis, staging, and measurement of response to treatment in patients with somatostatin receptor positive tumors. Goals are to 1) compare this unique PET/CT scan with the current standard of care which is a combination of Octreoscan SPECT (single photon emission tomography) plus a high resolution, contrast enhanced CT; 2) Determine the sensitivity of 68Ga-DOTATOC PET/CT in diagnosis of patients with suspected somatostatin receptor positive tumor; and 3) For those patients who have had recent treatment (e.g., surgery, chemotherapy, targeted therapy such as anti-angiogenics, kinase inhibitors, peptide receptor radiotherapy), this scan will be used to measure response to treatment. These studies will be obtained with the long term goal of submitting a New Drug Application (NDA) for FDA approval of 68Ga-DOTATOC PET/CT in adults and children.

The purpose of this study is to assess the benefit of 177Lu-DOTATATE versus interferon α-2b in patients with progressive, unresectable, non-pancreatic gastrointestinal neuroendocrine tumors resistant to therapy with somatostatin analogues, in terms of disease control.

The goal of this proposal is to produce and test high specific activity Ultratrace iobenguane I 123 in normal human volunteers.

The phase I trial aims to determine the recommended phase II dose (RP2D) of vandetanib in combination with standard radiation therapy, 131I-mIBG, in patients with advanced phaeochromocytoma (phaeo) and paraganglioma (PG) by assessing the safety and tolerability of the combination treatment.

To evaluate the concordance and discordance between results of 68Ga-DOTATATE PET-CT scan and OctreoScan ® which is considered standard of care diagnostic test for neuroendocrine cancers and other imaging modalities like CT scan/MRI as gold standard.

LM3 is a novel somatostatin receptor antagonist, while Gallium-68 DOTATATE is a typical somatostatin receptor agonist, This study is to evaluate the safety, biodistribution, dosimetry, and lesion detection ability of Gallium-68 labeled somatostatin receptor antagonist LM3 for the diagnostic imaging of metastatic, well-differentiated neuroendocrine tumors using positron emission tomography / computed tomography (PET/CT). The results will be compared between antagonist Gallium-68 labeled LM3 and agonist Gallium-labeled DOTATATE in the same group of patients. It will also be compared between the two different antagonists, Gallium-68 DOTA-LM3 and Gallium-68 NODAGA-LM3, in two parallel-designed arms.
