Active clinical trials for "Neuroendocrine Tumors"

This phase II trial studies how well nintedanib works in treating patients with neuroendocrine tumors that have spread from where they started to nearby tissue or lymph nodes (locally advanced) or have spread from the primary site (place where they started) to other places in the body (metastatic). Nintedanib may stop the growth of tumor cells by slowing or stopping a certain type of receptor called vascular endothelial growth factor receptor (VEGFR) from attaching to its target. This may stop the growth of neuroendocrine tumors by blocking the growth of new blood vessels necessary for tumor growth.

A randomized, double-blind, placebo controlled, multi-center Phase III study to assess the efficacy of Surufatinib 300 mg once a day in treating advanced extrapancreatic neuroendocrine tumors.

The therapeutic goals in the management of pancreatic neuroendocrine tumors (pNET) are the control of symptoms and tumor growth control in order to improve patient survival. In recent years, data from two phase III studies with targeted therapies, sunitinib and everolimus, have broadened the possibilities for treatment of patients with neuroendocrine tumors of the pancreas. Unfortunately, patients progress and development of new active drugs and evaluating the best treatment approach is decisive. Given the lack of data comparing the activity of different treatment strategies, final decisions are based on medical experience and consensus of experts. In this context, different questions are still unanswered, as which is the best sequence of treatment and if all patients can benefit from all available drugs. Neuroendocrine pancreatic tumors are highly vascularized tumors in which cells may be dependent on this pathway for growth throughout the entire history of the tumor and in which inhibition of this pathway is crucial. On the other hand, this aspect has not been endorsed by the population of patients with pNET who have previously failed treatment with sunitinib. In this scenario the investigators will assess retreatment with sunitinib to evaluate the activity of this drug in the context of therapeutic rescue in patients with metastatic pNET.

This study will evaluate long-term safety and tolerability of pasireotide LAR in combination with everolimus in advanced metastatic NET patients, who who have not progressed during 12 months of combination therapy with pasireotide LAR and everolimus

Protocol PEN-221-001 is an open-label, multicenter Phase 1/2a study evaluating PEN-221 in patients with SSTR2 expressing advanced gastroenteropancreatic (GEP) or lung or thymus or other neuroendocrine tumors or small cell lung cancer or large cell neuroendocrine carcinoma of the lung.

This is a Phase 1, multiple dose, ascending dose escalation study; to define a MTD/RD and regimen consisting of a first "priming" dose and escalated subsequent doses of XmAb18087; to describe safety and tolerability; to assess PK and immunogenicity; and to preliminarily assess anti-tumor activity of XmAb18087 in subjects with advanced NET or GIST. The study will enroll dosing cohorts to establish a MTD/RD and regimen in subjects with advanced NET or GIST, then enroll additional subjects into separate NET and GIST expansion cohorts to collect additional data on safety and potential efficacy of XmAb18087.

GI tract including pancreas is the one of most common primary sites of neuroendocrine tumors. Current grading of neuroendocrine tumors are based on the 2010 WHO classification. This classifies grade 3 tumors as the neuroendocrine tumor with mitosis > 20 per 10 high power field or Ki-67 labeling index > 20%. Etoposide-based chemotherapy, mostly as the combination with cisplatin, has been the mainstay of the treatment for patients with grade 3 neuroendocrine tumors. However, a recent large retrospective analysis has suggested this regimen may not be effective in relatively low Ki-67 labeling index. Therefore, the investigators designed a clinical trial testing temozolomide-capecitabine combination, which has been mostly investigated in well differentiated (ie., grade 1 or 2) neuroendocrine tumors, in patients with grade 3 and low Ki-67 gastroenteropancreatic neuroendocrine tumors.

This study is for patients with non-resectable, recurrent, or metastatic well or moderately differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NETs). The study will be conducted in two stages: 1) Safety Run-In and 2) Expanded Cohort. Safety run-in: The first stage will include a safety run-in of 6 patients treated with pembrolizumab 200 mg intravenous (IV) every 3 weeks and lanreotide depot 90mg subcutaneous (SQ) every 3 weeks. Up to 6 patients at the Duke Cancer Institute will be accrued at the starting dose level. If one or less subject meets treatment-related discontinuation criteria (as specified in the protocol) during Cycle 1, then the study will proceed to the second stage, Expanded Cohort. Expanded Cohort: Patients will be treated with pembrolizumab 200mg IV every 3 weeks and lanreotide depot 90mg SQ every 3 weeks as determined by the Safety Run-In Cohort.

The purpose of this study is to learn if a new drug, ONC201 can make tumors become smaller or go away completely. Investigators also want to learn if ONC201 can prevent new deposits of cancer from appearing in new places in participants (metastases). A phase 2 study of ONC201 in PC-PG (pheochromocytoma-paraganglioma) and other neuroendocrine tumors will determine whether inhibition of DRD2 (a member of the dopamine receptor family) is safe in unresectable, recurrent, locally advanced, refractory, or metastatic neuroendocrine cancers including PC-PG, desmoplastic small round cell tumor (DSRCT), Ewing sarcoma (PNET) or any other neuroendicrine tumor with a catecholamine or dopamine biomarker or autocrine or paracrine dependence on dopamine including cholangiocarcinoma and adrenal cortical carcinoma. ONC201 is an investigational (experimental) agent and has a favorable safety profile in phase 1 and early phase 2 clinical trials in advanced cancers. This study design has been chosen to see whether ONC201 is associated with reduction of anti-hypertension medications, safety and significant efficacy against neuroendocrine tumors, especially PC-PG.

Phaeochromocytomas and paragangliomas (PPGLs) are tumours of the adrenal medulla and extra-adrenal sympathetic nervous system, some which can become metastatic. It is a very rare disease and the tumours are often detected late. Approximately 50 % of the tumours are caused by germline genetic variants screening programmes are recommended for patients and their family members; however, they are not yet well-targeted with respect to individual prognosis. In this study the investigatorscaim to characterize the genotype-phenotype associations in all Danish patients (n=400) diagnosed with PPGLs who have been followed in tertiary centres using medical records and national registries. To this end novel immunohistochemical, genetic, and epigenetic biomarkers in tumour tissues samples from biobank material (blood samples and tumour tissue) will be investigated to develop a comprehensive predictive algorithm for disease prognosis. The study will provide a clinical tool for an improved targeted screening program and subsequently prevention of disease development.
