PART 1: Imaging with OTSA101 DTPA-111In OTSA101-DTPA-111In (1.5mg OTSA101-DTPA radiolabeled with 185 MBq of 11In) will be administered intravenously (IV) as a single injection on Day -28 (D-28). Patients will undergo serial anterior-posterior gamma scans and single photon emission computed tomography (SPECT/CT) at 1, 5, 24, 48, 72, 144 hours post-dosing to estimate absorbed radiation doses to tumor, to normal organs (i.e., liver, lung, kidney, and bone marrow), and whole body in order to determine OTSA101-DTPA-111In tumor uptake (ID%/g [% of injected dose (ID) per gram of tumor]) and biodistribution (ratio tumor/normal tissue of estimated radiation-absorbed dose). PK sampling will be performed at the same time points with additional sampling at D-14 and D0.
