Active clinical trials for "Carcinoid Tumor"

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.

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 primary hypothesis of this study is that panitumumab, an inhibitor of the epidermal growth factor receptor (EGFR), is an effective treatment for carcinoid syndrome in people who fail or do not adequately respond to octreotide or other supportive therapies.

The purpose of this study is to see if the use of 68Gallium- positron emission tomography and computer tomography (PET/CT) scans along with NETSPOT® (Advanced Accelerator Applications USA, Inc.) can better define the localization of Neuroendocrine tumors enhancing the surgical removal of Neuroendocrine tumors (NETs).

The goal of this study is to compare several methods for measurement of Chromogranin A in their ability to serve as a marker for disease activity in patients with neuroendocrine tumors. Further, in a subgroup, we will determine if taking a proton pump inhibitor affects Chromogranin A levels.

This research study is designed to evaluate a type of scan called Ga-68-DOTA-TOC positron emission tomography (PET) scanning as a way of assessing carcinoid tumors.

RATIONALE: Vatalanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by stopping blood flow to the tumor. Octreotide may help control symptoms, such as diarrhea, caused by the tumor. Giving vatalanib together with octreotide may be an effective treatment for neuroendocrine tumors. PURPOSE: This phase II trial is studying how well giving vatalanib together with octreotide works in treating patients with progressive neuroendocrine tumors.

The purpose of this study is to test the safety of a drug called Ultratrace iobenguane I 131 that has radioactivity, to measure how long it takes for the drug to be absorbed and passed out of the body, and to measure how much radioactivity is absorbed into different tissues of the body.

This is a randomized phase III clinical trial of Lanreotide combined with Telotristat ethyl or placebo for the first-line treatment in patients with advanced well differentiated small intestinal neuroendocrine tumours (siNET) with highly-functioning carcinoid syndrome to test whether telotristat ethyl plus lanreotide is more effective than placebo plus lanreotide in reducing the number of daily bowel movements. In addition, the study allows evaluation of the biochemical response (5-HIAA and chromogranin-A), the reduction in the number of daily cutaneous flushing episodes, the improvement in abdominal pain/discomfort, health-related quality of life, improvement in gastro-intestinal and endocrine symptoms, changes in emotional functioning, the impact of discontinuation of telotristat ethyl/placebo on HRQOL and symptoms, and the safety and toxicity of the treatment. Patients will enter into a screening/run-in period of 1 week to establish baseline characteristics and symptomatology. The baseline assessment of daily bowel movement, as assessed in an electronic diary, will be averaged over the run-in period. Following the screening/run-in period, patients will be randomly assigned (1:1) to either the control arm or the experimental arm for 12 months. Randomization will be stratified according to the grade of tumour differentiation (grade 1 vs. grade 2) and by baseline number of bowel movements per day (4-6 versus >6). A total of 94 patients will be randomly assigned (1:1) to either arm. Upon randomization, all patients will enter the 12-month treatment period with lanreotide + telotristat ethyl/placebo (blinded). In the experimental arm, patients will receive the deep subcutaneous injection of lanreotide (120 mg) every 28 days and 250 mg orally three times daily (TID) of telotristat ethyl for 12 months. In the control arm, patients will receive the deep subcutaneous injection of lanreotide every 28 days (120 mg) and placebo orally TID for 12 months. After completion of a minimum of 6 months on randomized blinded-treatment, the protocol allows for patients on treatment with telotristat ethyl/placebo to be unblinded in the event of "lack of symptom control". Unblinding due to "lack of symptom control" can happen at any time between 6 and 12 months of the blinded-treatment period. After unblinding, patient will interrupt protocol treatment and will be further treated as per clinician discretion. All patients will be unblinded after a maximum of 12 months on randomized blinded-treatment. After a follow-up of 12 months, patients will go off study except patients with carcinoid heart disease. Patients off study will be further treated as per clinician discretion. Patients with carcinoid heart disease will continue open-label treatment on study (lanreotide + telotristat ethyl or lanreotide alone according to what they were receiving at unblinding at 12 months) for 4 additional years (open-label extension period). Patients with carcinoid heart disease who discontinue protocol treatment before 12 months will also enter the extension period for additional follow-up. Additional follow-up will last 4 years for these patients and will include 6-monthly cardiological assessments. All efficacy analyses will be conducted in the Intention-to-treat population as primary analyses i.e. all 94 randomized patients will be analyzed in the arm they were allocated by randomization. Safety analyses will be performed on the Safety population i.e. on all patients who have received at least one dose of the study drugs. The translational research projects include blood metabolite discovery and targeted assays to find new biomarker candidates of response to Telotristat. Human biological material that will be collected for translational research purpose: whole blood, plasma and serum at baseline, 4 hours after first dose, 4 weeks, 12 weeks and at end of treatment visit with telotristat/placebo (due to end of study, disease progression or lack of benefit) archival tissue samples (formalin-fixed paraffin-embedded) will be retrieved for all patients at study entry. In addition, one EDTA blood tube of whole blood (10 ml) at baseline, 12 weeks and end of treatment (EOT visit) might be also collected for not yet pre-defined and further translational research. Quality of life will be assessed with the EORTC Quality of Life Questionnaire (QLQ-C30) version 3, together with the QLQ-GI.NET21 specific module designed for Neuroendocrine Tumours. The computer-adaptive testing (CAT) diarrhea scale will also be used. The baseline questionnaires must be completed during the screening period and before randomization. Subsequent questionnaires are completed at 4 weeks, 12 weeks, 24 weeks, 36 weeks and 52 weeks. Once a patient has stopped treatment, HRQoL data collection for that patient is required 1 month (28-35 days) after protocol treatment discontinuation.

This is an open-label, single-arm, multi-site phase I/Ib trial with SYD985, an antibody-drug conjugate (ADC) targeting HER2 on the cell membrane, combined with paclitaxel.
