Expanded Access Program of Ultratrace Iobenguane I131 for Malignant Relapsed/Refractory Pheochromocytoma/Paraganglioma

Study Overview
=================
Brief Summary
-----------------
The purpose of this sub-study is to provide expanded access of AZEDRA (Ultratrace Iobenguane I 131) and to evaluate the safety and tolerability of AZEDRA in subjects with iobenguane-avid malignant and/or recurrent pheochromocytoma/paraganglioma (PPGL).

Detailed Description
-----------------
MIP-IB12B, the pivotal phase 2 study evaluating efficacy and safety of AZEDRA in patients with malignant relapsed/refractory PPGL, has completed its anticipated enrollment. The purpose of this sub-study, MIP-IB12B-EAP, is to provide expanded access to AZEDRA for newly enrolled subjects with iobenguane-avid metastatic and/or recurrent PPGL and to collect additional safety data.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Drug: Ultratrace Iobenguane I131|Subjects will receive a dosimetry dose of AZEDRA and will undergo 3 whole body scans. If the scans indicate tumor avidity for AZEDRA, the subjects will receive up to 2 therapeutic doses of AZEDRA each at 500 mCi (or 8 mCi/kg, for subjects weighing 62.5 kg or less) approximately 90 days apart.|
