Many of these cancers have a high risk of relapse and a low chance of survival. Better treatments are needed.\n\nObjective:\n\nTo test a new drug, ADCT-701, in people with NENs.\n\nEligibility:\n\nAdults aged 18 and older with NENs.\n\nDesign:\n\nParticipants 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.\n\nADCT-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.\n\nParticipants may continue receiving treatment with the study drug for up to 2 years.\n\nAfter 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.\n\nFollow-up visits will continue for up to 5 years after treatment began....","Background:\n\n-Neuroendocrine neoplasms (NENs) are divided into neuroendocrine tumors (NETs) and neuroendocrine carcinomas (NECs). These are rare malignancies occurring in areas such as the gastrointestinal tract, islets of the pancreas, lung, adrenal gland, and other areas of\n\nthe body.\n\n* Poorly differentiated neuroendocrine carcinomas are all high-grade carcinomas that resemble small-cell lung cancer (SCLC). Poorly differentiated NECs are also treated with platinum-based regimens in accordance with small cell carcinoma guidelines and have a high risk of relapse as well as a poor response to further systemic therapies.\n* Adrenocortical carcinoma (ACC) is a rare malignancy with an average survival from the time of diagnosis of 14.5 months. In advanced diseases, chemotherapy options have limited benefits. To date, no \"targeted therapy\" has been shown to have significant efficacy in this disease.\n* Malignant peripheral nerve sheath tumors (MPNST) are the most common Neurofibromatosis Type 1 (NF1) associated malignancy and leading cause of death in patients with NF1 with no effective medical therapies available.\n* Pre-clinical studies have shown that Delta-like non-canonical notch ligand 1 (DLK1) is expressed in multiple neuroendocrine neoplasms such as ACC, SCLC, neuroblastoma, pheochromocytoma, paraganglioma, and MPNST.\n* ADCT-701 a humanized antibody directed against DLK1 effectively suppresses tumor growth and improves survival in multiple cancer models which express DLK1.\n\nObjective:\n\n-To determine the maximum tolerated dose (MTD) of ADCT-701 in participants with neuroendocrine neoplasms, malignant adrenocortical carcinoma or malignant peripheral nerve sheath tumor (MPNST)\n\nEligibility:\n\n* Histologically or cytologically confirmed neuroendocrine neoplasms, malignant ACC, or refractory or metastatic MPNST.\n* Age \\>= 18 years.\n* Evaluable disease, per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.\n* Adequate organ and bone marrow function.\n* Eastern Cooperative Oncology Group (ECOG) \\\u003C= 2.\n\nDesign:\n\n* This is a First in Human phase I dose escalation study of ADCT-701-single agent in participants with NENs or MPNST.\n* Participants will be enrolled in a dose-finding trial.
