A UGT1A1 Genotype-Directed Study of Belinostat Pharmacokinetics and Toxicity

Background: High-grade neuroendocrine carcinomas (HGNEC) are cancers that develop in different parts of the body, including the digestive tract, genitals, neck, and head. One drug (belinostat), combined with 2 other drugs (etoposide and cisplatin), is approved to treat HGNEC. But some people may have a gene variant that affects how quickly their body gets rid of the drug; these people may do better with different dosages of belinostat. Objective: To test higher or lower doses of belinostat based on gene variants in people with HGNEC. Eligibility: People aged 18 years and older with HGNEC. Design: Participants will be screened. They will have a physical exam with blood tests. Some blood will be used for genetic testing. They will have imaging scans and a test of their heart function. Samples of tumor tissue may be collected. All 3 study drugs (belinostat, etoposide, cisplatin) are given through a tube attached to a needle inserted into a vein. Treatment will be given in 21-day cycles. For cycles 1 through 6: Participants will come to the clinic for the first 4 days. They will be given all 3 drugs. Imaging scans and other tests will be repeated. Each visit will last 4 to 8 hours. After cycle 6: Participants may continue treatment with belinostat alone. They will come to the clinic for the first 3 days of each cycle. They may continue treatment for up to 5 years if the drug is helping them. Participants will have a follow-up visit 30 days after their last dose of belinostat. Then they will receive follow-up visits by phone or email every 3 to 6 months.

A First-in-Human Phase I Trial With Antibody Drug Conjugate ADCT-701 in Neuroendocrine Tumors, Carcinomas and Malignant Peripheral Nerve Sheath Tumors

Background: Neuroendocrine neoplasms (NENs) are rare cancers in the gastrointestinal tract, pancreas, lungs, adrenal glands, and other areas of the body. Many of these cancers have a high risk of relapse and a low chance of survival. Better treatments are needed. Objective: To test a new drug, ADCT-701, in people with NENs. Eligibility: Adults aged 18 and older with NENs. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have imaging scans and tests of heart functioning. Their ability to perform normal daily activities will be tested. A biopsy may be needed: A sample of tissue will be removed from the tumor. ADCT-701 is given through a tube attached to a needle inserted into a vein in the arm. Participants will receive the drug treatment on the first day of 21-day treatment cycles. They will visit the clinic a total of 10 times during the first two cycles. After that, they will visit the clinic 2 times during each cycle. Imaging scans, blood draws, heart function tests, and other tests will be repeated during study visits. Each visit will last up to 8 hours. Participants may continue receiving treatment with the study drug for up to 2 years. After treatment ends, participants will have follow-up clinic visits 4 times in 4 months. They will have a physical exam, with heart and blood tests, at each visit. After that, they will have follow-up clinic visits every 9 weeks; these visits will include imaging scans. Follow-up visits will continue for up to 5 years after treatment began....

Trial of FOLFIRI + Zimberelimab + Domvanalimab vs FOLFIRI With a Hybrid Synthetic Control Arm in Second Line Treatment of Neuroendocrine Carcinoma of Gastro-enteropancreatic or Unknown Origin (REWENEC 01)

Background Neuroendocrine carcinomas (NECs) of gastro-entero-pancreatic (GEP) or unknown (UK) origin are rare and highly aggressive diseases. The recommended first-line (L1) treatment is platinum-etoposide combination therapy, which has a progression-free survival (PFS) of only 4-9 months and a median overall survival (OS) of approximately 12 months. All patients experience relapse, often rapidly after this first line of chemotherapy. The standard second-line (L2) chemotherapies recommended by ESMO, ENETS, and NCCN, FOLFIRI and FOLFOX, have modest efficacy with a PFS of 3 months and a median OS of 6 months. The BEVANEC study (PHRCK 2014, NCT02820857) reported no benefit of FOLFIRI + bevacizumab compared to FOLFIRI in a randomized phase II study that enrolled 150 patients in 26 centers over a period of 5 years in France. To date, the most promising efficacy data for this highly aggressive cancer come from clinical trials of immune checkpoint inhibitors (ICIs) targeting the PD-1/PD-L1 checkpoint. For example, in France, the non-comparative phase II NIPINEC trial (NCT03591731) randomized patients to receive nivolumab +/- ipilimumab in L2/3 and achieved its primary evaluation criterion (ORR-8 weeks\>10%). Other trials in Europe and worldwide have also reported efficacy data in the context of single-arm studies. Scientific Questions and Unmet Needs: 1. New therapeutic options/perspectives are necessary for patients with GEP/UK NECs given the limited overall survival. 2. Approximately 50% of patients experienced early progression under immunotherapy in the NIPINEC trial and other trials, which may be explained by the absence of chemotherapy combined with immunotherapy and/or the existence of resistance mechanisms. 3. In the GEP/UK NEC indication, the design of these immunotherapy trials has been non-comparative single-arm studies because the realization of randomized comparative trials is considered very difficult for these very rare cancers (incidence \<5/million). Rationale for the REWENEC-01 Trial The DURIGAST PRODIGE 59 study, conducted by the FFCD, demonstrated the feasibility and safety of the FOLFIRI + double immune checkpoint inhibitor (anti-PD-1 and anti-CTLA4) combination, as well as for the combination Folfox-Domvanalimab-Zimberelimab (anti-PD-1 and anti-TIGIT). In a translational study of the immune phenotype in patients with NECs treated with the anti-PD1 pembrolizumab, an increase in TIGIT expression was observed after pembrolizumab treatment and higher TIGIT expression on T cells in the blood of patients with high Ki67 expression in their tumors. These data suggest that TIGIT is a potential complementary therapeutic target to PD-1/PD-L1 checkpoint inhibition in GEP/UK NECs. Domvanalimab has been developed as an anti-TIGIT monoclonal antibody and zimberelimab as an anti-PD-1. Design and primary objective of the REWNEC-01 Trial The REWENEC-01 trial is a comparative phase II trial that will randomize GEP/UK NEC patients between an experimental arm FOLFIRI+Zimberelimab + Domvanalimab and a control arm FOLFIRI in L2. The FOLFIRI arm will be a "hybrid" synthetic control arm composed of patients from historical/external data from the FOLFIRI arm of BEVANEC and French retrospective studies RBNEC and CEPD, mixed with patients recruited prospectively during the trial and randomized to the control arm. The randomization ratio for patients included prospectively during the trial will be 4:1 (4 patients assigned to FOLFIRI+Zimberelimab + Domvanalimab for 1 patient assigned to FOLFIRI). The randomization algorithm will take into account "external" patients assigned progressively to the control arm to obtain a 1:1 ratio between the trial arms, with balanced distributions of stratification factors between the two arms. With 77 patients to be included, this strategy will provide statistical power equivalent to that of a trial including 122 patients, sufficient to demonstrate an advantage in overall survival rate at 12 months from 32% to 50%. The hypotheses related to efficacy criteria are formulated a priori, as recommended by the FDA guidance document on trials with synthetic/external control arms. The proof of concept has been reported at ESMO 2023. The primary judgment criterion will be the overall survival rate at 12 months because it is a strong and significant criterion for translating the clinical benefit of the Chemotherapy + Zimberelimab + Domvanalimab combination. The design with a hybrid synthetic control arm allows for the consideration of a randomized comparative study in a cancer as rare as neuroendocrine carcinoma.

Tissue Procurement and Natural History Study of Neuroendocrine Neoplasms (NENs) Including Adrenocortical Carcinoma (ACC)

Background: Neuroendocrine neoplasm (NENs)are rare cancers arising from the neuroendocrine cells and can affect almost any part of the body. They vary from low grade neuroendocrine tumors (NETs) to high grade neuroendocrine carcinomas (NECs). These tumors often occur in the gastrointestinal tract, pancreas, lungs, adrenal medulla (pheochromocytomas) or adrenal cortex (adrenocortical cancer) and other areas of the body mentioned below: * Gastroenteropancreatic neuroendocrine tumors (GEP-NET): stomach, duodenum, pancreas, colon, appendix, etc. * Liver and gallbladder * Adrenal tumors * Pituitary gland * Thyroid gland: medullary thyroid carcinoma * Parathyroid tumors * Pulmonary neuroendocrine tumors: typical and atypical carcinoid, small cell lung cancer (SCLC), large cell neuroendocrine carcinoma (LCNEC) * Extrapulmonary small cell cancer * Peripheral nervous system tumors: paraganglioma, neuroblastoma) * Breast and genitourinary tract Their rates are rising in the United States and worldwide. Researchers want to learn more about NENs through this natural history study. Objective: To study the natural history of people with NENs and obtain samples from them to learn more about the disease. The clinical management of all NETs is not standardized, with only a few FDA-approved therapies and we would like to learn which combination therapeutic approach should be used, how long treatment should be continued, and in what subgroup of NENs a particular treatment option should be used. Eligibility: People aged 18 and older who have or are suspected to have NENs or ACC. Design: Participants will be screened with a medical history. Participants will have a physical exam. Their symptoms and their ability to perform their normal activities will be reviewed. They will have blood and urine tests. Participants will receive recommendations for managing their disease and potential treatment options. They will be able to ask as many questions as they would like. Participants may provide saliva and blood, a for research. They will give tumor samples from a previous surgery or biopsy. Participants may have optional biopsies. During biopsies, cancer tissue will be obtained using a needle and syringe. Tissue will be taken from the liver, lung, or a lymph node. Participants may have an imaging scan or ultrasound to help locate the tumor or area to be biopsied. They will receive local anesthesia and may be sedated. Participants will complete a questionnaire about their family medical history. Participants will have follow-up visits every 12 months. They will have physical exams and give samples. If their health changes, they may have extra visits. If they cannot visit NIH, they (or their doctor) will be contacted by phone or email. Participants will take part in the study for all their life.

Mass Response of Tumor Cells as a Biomarker for Rapid Therapy Guidance (TraveraRTGx)

The primary objective of this study, sponsored by Travera Inc. in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from various specimen formats including malignant fluids such as pleural effusions and ascites, core needle biopsies, fine needle aspirates, or resections.

A Trial to Assess the Safety and Effectiveness of Lutetium-177 Octreotate Therapy in Neuroendocrine Tumours

Neuroendocrine tumours (NETs) are rare, slow growing, and diagnosis is often delayed with advanced metastases at presentation. In select patient populations, radioisotope therapy with Lutetium-177 (Lu-DOTA-TATE) has been shown to be a safe and effective palliative therapy, and has been widely used by research groups in Europe. A brand of Lu-DOTA-TATE (Lutathera(R)) is approved for the treatment of gastroenteropancreatic NETs in Europe, the U.S., and more recently in Canada. While Lutathera(R) is approved in Canada, it is not publicly funded in Alberta. Lu-DOTA-TATE has been used at the Cross Cancer Institute to treat more than 300 patients with NETs since August, 2010. Our Lu-DOTA-TATE treatment was initially given under Health Canada's Special Access Programme (SAP), with each individual treatment requiring separate approval. In 2014, Health Canada requested we conduct a clinical trial with Lu-DOTA-TATE instead. The purpose of this study is to: 1) assess the efficacy of Lu-DOTA-TATE treatment in patients with somatostatin receptor positive tumours; 2) assess the safety of Lu-DOTA-TATE; 3) assess the effect of Lu-DOTA-TATE on Quality of Life and survival.

Personalized PRRT of Neuroendocrine Tumors

In this study, peptide receptor radionuclide therapy (PRRT) with 177Lu-Octreotate (LuTate) will be personalized, i.e. administered activity of LuTate will be tailored for each patient to maximize absorbed radiation dose to tumor, while limiting that to healthy organs. The purpose of this study is to: * Assess the objective (radiological), symptomatic and biochemical response rates following an induction course of personalized PRRT; * Assess the overall, the disease-specific, and the progression-free survival following P-PRRT; * Correlate therapeutic response and survival with tumor absorbed radiation dose; * Evaluate the acute, subacute and chronic adverse events following P-PRRT; * Correlate toxicity (i.e. occurence and severity of adverse events) with absorbed radiation doses to organs at risk; * Optimize the quantitative SPECT imaging-based dosimetry methods in a subset of 20 patients (sub-study funded by the Canadian Institutes of Health Research). This study also has a compassionate purpose, which is to provide access to PRRT to patients.
