REFIT-MSS
Start date: April 30, 2023
Phase: Phase 2
Study type: Interventional

REFIT-MSS is a non-randomized, multicenter, open-label, multi-cohort, 2-stage, phase II trial to evaluate the efficacy and safety of regorafenib in combination with tislelizumab (referred as Rego-Tisle) in adult patients with select advance, previously treated, Mismatch Repair-Proficient/Microsatellite (pMMR/MSS) stable solid cancers. The multi-cohort design will allow for the examination of 8 separate cohorts of different cancers to determine whether further examination may be warranted in the individual indications.

NCT ID: NCT04915144 Withdrawn - Clinical trials for Neuroendocrine Tumors

177Lu-DOTATOC for the Treatment of Patients With Somatostatin Receptor Positive NETs

Start date: January 15, 2023
Phase: Phase 2
Study type: Interventional

This study is to assess if personalized peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATOC results in fewer adverse events than standard PRRT. Subjects will be randomized to either receive personalized or standard PRRT. Personalized PRRT will be determined based on dosimetry calculations after the first cycle. In addition comparisons, will be made with progression-free survival, serial CT imaging, ctDNA, and quality of life questionnaires. Subjects will be followed for 5 years or until they have progression and are switched to another systemic treatment (not including treatment with somatostatin analogues).

NCT ID: NCT04831567 Withdrawn - Clinical trials for Neuroendocrine Tumors

Study of MIBG-I131 in Patients With Well Differentiated Neuroendocrine Tumors

MIBNET
Start date: February 4, 2021
Phase: Phase 2
Study type: Interventional

This is a single-arm, unicentric, single-stage, phase 2 clinical study of therapeutic metaiodobenzylguanidine (MIBG) for patients with metastatic well-differentiated neuroendocrine tumors and radiological progression or intolerance after standard lines of treatment and with MIBG positive scan.

NCT ID: NCT04776876 Withdrawn - Carcinoid Syndrome Clinical Trials

Retifanlimab (INCMGA00012) and Telotristat Ethyl for the Treatment of Advanced Neuroendocrine Tumors and Carcinoid Syndrome

Start date: March 1, 2021
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT04713202 Withdrawn - Diarrhea Clinical Trials

Prospective Assessment of Patients With Neuroendocrine Tumors and Current or Prior History of Carcinoid Syndrome or Diarrhea Undergoing Peptide Receptor Radionuclide Therapy With or Without Telotristat Ethyl

NET-PACS
Start date: March 3, 2021
Phase: Phase 2
Study type: Interventional

The NET-PACS trial is a Prospective Assessment of patients with neuroendocrine tumors and current or prior history of Carcinoid Syndrome or diarrhea undergoing peptide receptor radionuclide therapy with or without telotristat ethyl. The main goal of the study is to demonstrate the feasibility of serial in-depth assessment of patients with neuroendocrine tumors and current or prior history of carcinoid syndrome or diarrhea undergoing treatment with PRRT using telotristat ethyl compared to placebo. We aim to report and describe from a patient's perspective the multi-faceted impact of carcinoid syndrome in patients with NETs and the changes on treatment while getting PRRT using telotristat ethyl compared to placebo.

NCT ID: NCT04672876 Withdrawn - Clinical trials for Neuroendocrine Tumors

Telotristat Ethyl for Reducing Intraoperative Carcinoid Crisis in Patients With Neuroendocrine Tumors

Start date: January 2022
Phase: Phase 2
Study type: Interventional

This is a study to determine if a certain drug, called telotristat ethyl (Xermelo®), can help reduce the chance of blood pressure and heart rate variations (known as carcinoid crisis) in individuals who have neuroendocrine tumors (also called carcinoid tumors). These complications can be life-threatening for patients who already have to experience challenging surgeries to remove their tumors. To determine if telotristat ethyl (Xermelo®) will help reduce these complications during surgery, researchers will give the drug to study participants before surgery.

NCT ID: NCT04614766 Withdrawn - Clinical trials for Neuroendocrine Tumors

A Clinical Trial Evaluating the Safety of Combining Lutathera(R) and Azedra(R) to Treat Mid-gut Neuroendocrine Tumors

SPORE-3
Start date: September 30, 2022
Phase: Phase 1/Phase 2
Study type: Interventional

This study is designed to identify the best tolerated doses of Lutathera® and Azedra® when co-administered to treat midgut neuroendocrine tumors. These drugs are radioactive drugs, known as radionuclide therapy, and are both approved in the treatment of midgut neuroendocrine tumor as single agents (not together). Currently, the safest and best tolerated doses of these drugs (when combined) is unknown. That is the purpose of this clinical trial.

The treatment regimen will consist of 4 doses of 200 (±10%) mCi 177Lu-DOTATOC administered at 8+/- 1-week intervals.

NCT ID: NCT04065165 Withdrawn - Clinical trials for Carcinoid Heart Disease

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

TELEFIRST
Start date: April 2020
Phase: Phase 3
Study type: Interventional

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.
