A Phase I Study of Lintuzumab-Ac225 in Patients With Refractory Multiple Myeloma

Overview

1. Establish the MTD of Lintuzumab-Ac225 as monotherapy 2. Establish overall response rate (ORR) where ORR = CR + sCR+ VGPR+PR) 3. Confirm the safety profile of the treatment regimen 4. Estimate progression-free survival (PFS) and overall survival
