Overview

Phase II study demonstrates blinatumomab enhances MRD-negativity in adults with B-cell ALL, suggesting improved outcomes through ASCT.

Key Points

  • Blinatumomab achieved a 73% MRD response rate after 4 cycles of treatment, with 65% of patients achieving MRD-negativity after Cycle 1.
  • Next generation sequencing revealed that 3 of 5 patients reached MRD-negativity at a 10-6 threshold, indicating effective minimal residual disease monitoring.
  • Allogeneic stem cell transplantation was undertaken by 33% of responders after treatment, supporting its role in long-term management.
  • Overall survival at 5 years was estimated at 60%, with notable improvements for patients achieving MRD <10-3.
