Filter by:Treatment of advanced endocrine tumors, including adrenal corticocarcnioma (ACC), medullary thyroid carcinoma (MTC), thymic neuroendocrine tumor and pancreatic neuroendocrine tumor is challenging. Previous genomic profiling studies showed they presented a number of somatic mutations. The tumors Individualized mRNA neoantigen vaccine provide a promising solution since a significant portion of these tumors showed high quality of tumor specific neoantigen. The primary objective is to observe and evaluate the safety and tolerability of individualized mRNA neoantigen vaccine (mRNA-0523-L001) for the treatment of advanced endocrine tumors, failure of standard treatment or no standard treatment currently available. The secondary objective is to observe the preliminary efficacy of mRNA-0523-L001 for the treatment of advanced endocrine tumors, failure of standard treatment or no standard treatment currently available, including: 1. Neoantigen-specific CD4+ and CD8+ T lymphocyte responses induced by mRNA-0523-L001; 2. Objective response rate (ORR) and disease control rate (DCR) of tumors; 3. Progression-free survival (PFS).
The goal of this prospective observational study is to generate new personalised 3D preclinical models of pancreatic neuroendocrine tumors. The models will be exploited for studying the mechanisms underlying disease development and progression, as well as for performing drug testing. For the development of the newly proposed models, patients' surgical specimens will be evaluated by the Pathological Unit. If the presence of pathological material in excess, not required for the routine diagnostic procedure, is confirmed, such material will be employed for the generation of the proposed personalised models.
This is a prospective cohort study. The investigators enroll subjects with pancreatic ductal adenocarcinoma (PDAC), individuals at high risk for PDAC, patients with other pancreatic diseases, patients with CA19-9 elevation and controls without pancreatic disease. This study aims to establish a diagnostic prediction model by using elastase 1, common clinical serological examinations, and imaging examinations including endoscopic ultrasonography (EUS), and to explore the diagnostic ability of the model in the high-risk population of PDAC. Besides, the investigators search for new biomarkers by multi-omics studies of serum and pancreatic tissues to further improve the diagnostic performance of this model. In conclusion, this study seeks a robust diagnostic prediction model to diagnose PDAC, especially early resectable PDAC.
A Phase 2 multi-center, open-label, single arm study of nab-sirolimus in patients with well-differentiated neuroendocrine tumors (NETs) of the gastrointestinal tract, lung, or pancreas who have not received prior treatment with mTOR inhibitors
This protocol will enroll patients with pancreatic adenocarcinoma and adenosquamous carcinoma (Cohort 1), gastrointestinal/pancreatic neuroendocrine neoplasms with Ki-67 > 20% (Cohort 2) and neuroendocrine prostate carcinoma (Cohort 3)). Each cohort will have its own interim analysis after enrollment of 10 patients. Subjects will be given a one-month (28 day) supply of study drug (ESK981). Subjects will be instructed to take 4 capsules, with or without food, once per day for 5 consecutive calendar days, then take a drug holiday for 2 consecutive days before repeating the 5 days on-2 days off cycle in sets of 4 weeks or 28 calendar days. Subjects will be asked to keep a pill diary noting the date they take their study drug.
This prospective study aims to evaluate the sensitivity and specificity of an integrated model using fragmentomic profiles of plasma cell-free DNA for early detection of pancreatic neuroendocrine tumors.
Doctors and researchers leading this study hope to learn more about peptide receptor radionuclide therapy (PRRT) in combination with cytoreduction (surgically removing tumors). They hope to learn if combining PRRT in combination with cytoreduction would be more effective than cytoreduction alone. PRRT itself is approved by the U.S. Food and Drug Administration (FDA) for people with PanNETs however the combination with cytoreduction is considered experimental. Your participation in this research will last about 2 years. The purpose of this research is to gather information on the safety and effectiveness of PRRT.
Neuroendocrine tumors (NETs) are relatively rare tumors, mainly originating from the digestive system, that tend to be slow growing and are often diagnosed when metastatic. Surgery is the sole curative option, but is feasible only in a minority of patients. Peptide Receptor Radionuclide Therapy (PRRT) has been experimented for almost 20 years and is an established effective therapeutic modality for well/moderately differentiated, inoperable or metastasized gastro-entero-pancreatic (GEP) and bronchial NETs. Clinical studies demonstrated that partial and complete objective responses can be obtained in up to 30% of patients. Side effects may involve the kidneys and the bone marrow and are usually mild. Renal protection is used to minimize the risk of a late decrease of renal function. A new application for P-NETs is preoperative PRRT. Since surgery is the only curative option for GEPNETs, preoperative PRRT could increase the efficacy of surgery. However, this modality has not been fully explored in dedicated studies and there are just few sporadic case reports that described the preoperative use of PRRT in pancreatic NETs who could then be operated on successfully. Moreover there are few experiences demonstrating the advantage of PRRT associated to surgery in a multidisciplinary setting. In addition, the possibility of detecting the circulating NET transcripts by means of transcriptome analysis could represent an early marker of response to PRRT and improve the patient management. Aim of this study is to evaluate the response and rate of R0 surgery in patients with unresectable or borderline resectable PNETs eligible to PRRT with 90Y-DOTATOC and correlate the response to the variation in circulating NET transcripts measured before and after the end of PRRT. It has been recently shown that a PCR-based 51 transcript signature is significantly more sensitive and efficient than single analytes (e.g. CgA) in NET diagnosis and follow up. 30 patients will be enrolled in the study; each of them will receive 1.85 GBq/cycle of 90Y-DOTATOC with a cumulative activity of 9.25-11.1 GBq in 5-6 cycles (depending on personalized dosimetry). Therapy response will be assessed by morphological (CT/MRI) and functional (PET/CT or Octreoscan) imaging after 3 and 6 months from the completion of PRRT and compared with transcript analysis. Based on literature reports we expect a response rate of about 35% of patients.
