Details and patient eligibility

About

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).

Full 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.
