Primary Outcome Measures:
  • Number of Patients with Adverse Events [ Time Frame: From baseline to 30 days after the last dose of study drug ] [ Designated as safety issue: Yes ]
  • Change from Baseline to 30days after the last ndose of MEDI-551 in laboratory data, vital signs, and ECG [ Time Frame: From baseline to 30 days after the last dose of study drug ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To characterize the drug concentrations in serum and effect on circulating lymphocyte populations and Ig levels [ Time Frame: From baseline to 3 months after the last dose of study drug ] [ Designated as safety issue: No ]
  • Immunogenicity of MEDI-551 by measuring anti-MEDI-551 antibodies [ Time Frame: From baseline to 3 months after the last dose of study drug ] [ Designated as safety issue: No ]
  • Anti-tumor activity of MEDI-551 using Complete Response Rate [ Time Frame: From the baseline to30 days after the last dose of study drug ] [ Designated as safety issue: No ]
