Determine the safety and effectiveness of Lu-177 DOTATOC in adult subjects with somatostatin receptor-expressing Pulmonary, Pheochromocytoma, Paraganglioma, Unknown primary, and Thymus neuroendocrine tumors or any other non-.GEP-NET.

The treatment regimen will consist of 4 doses of 200 (10%) mCi 177Lu-DOTATOC administered at 8+/- 1-week intervals.
