Clinical Trial Summary

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.

Description:

Neuroendocrine tumors (NET) are rare neoplasms, which frequently present metastatic and incurable at diagnosis. In this context, few effective therapies exist. When the disease becomes refractory to standard therapies, treatments with limited efficacy (eg, surgical debulking, cytotoxic chemotherapies, interferon alpha) that could lead to important adverse events are used. Therefore, clinical studies that test new therapeutic strategies in NET patients with refractory disease are needed. Treatment with radiopharmaceuticals have been studied in NET and showed to be promisor. As an example, is the treatment with Lutetium177 octreotate, disponible in Brazil for decades, and one of the most active therapeutic options to NET. The radiopharmaceutical MIBG-I131 (metaiodobenzylguanidine linked to Iodine131) is the first treatment choice for patients with paraganglioma/pheochromocytoma (PggF), a rare type of neuroendocrine neoplasm originated from neural ganglia. Patients with this neoplasia are submitted to scintigraphy with MIBG-I131, a norepinephrine analog whose transporter protein is highly expressed in this tumor. If the uptake is positive, patients receive treatment with therapeutic doses of MIBG-I131. The disease control with this intervention could last two years. Old and small studies suggested that MIBG-I131 could also have an activity in other NET besides PggF. Gastrointestinal (GI) or lung NET could have a positive expression on MIBG-I131 scan in up to 50% of the cases. With this rationale, retrospective series reported that MIBG-I131 could offer clinical benefit in patients with GI NET, with disease control in up to 80% of the cases. However, the literature regarding therapeutic MIBG-I131 to NET not PggF is scarce, heterogeneous regarding population, methods of response assessment, doses of the radiopharmaceutical, and short follow-up time. Therefore, due to the absence of effective therapeutic options for patients with metastatic well-differentiated NET refractory to standard treatments, the evidence that NET can have a positive expression on MIBG-I131 scan, and that small retrospective studies with a low level of evidence suggest a benefit for control disease and improvement of symptoms, the investigators proposed a phase II study of MIBG-I131 to well-differentiated GI or lung NET patients with positive MIBG-I131 scan.
