Primary Outcome Measures:
  • Incidence of adverse events [ Time Frame: Through 1 month post last dose ]
  • Incidence of laboratory abnormalities [ Time Frame: Through 1 month post last dose ]

Secondary Outcome Measures:
  • Objective response according to modified response criteria for acute myeloid leukemia (Cheson 2003) or revised response criteria for malignant lymphoma (Cheson 2007) [ Time Frame: Through 1 month post last dose ]
  • Duration of response [ Time Frame: Until disease progression or start of new anticancer treatment, an expected average of 3 months ]
  • Overall survival [ Time Frame: Until death or study closure, an expected average of 6 months ]
  • Blood concentrations of SGN-CD19A and metabolites [ Time Frame: Cycles 1, 2, and 4: predose, 30 minutes, and up to 2, 4, 8, 24, 72, 120, 168, and 336 hours post dose start; All other cycles: predose, 30 minutes, and 168 and 336 hours post dose start; and 1 month post last dose ]
  • Incidence of antitherapeutic antibodies [ Time Frame: Predose in most cycles and 1 month post last dose ]
