About this trial
Phase I dose escalation study of 211At-MABG in adults with advanced pheochromocytoma / paraganglioma (PPGL) or other NET-overexpressing cancers (as evidenced by positive MIBG imaging) who are refractory to, lacking, or ineligible for approved treatments. Phase 1 dose-escalation will follow a standard 3+3 design with an expansion cohort at the recommended phase two dose (RP2D).
