Primary Outcome Measures:
  • Identification and characterization of changes in clonal populations of B cells in children with ALL [ Designated as safety issue: No ]
  • Reclassification of patients as MRD positive at day 29 [ Designated as safety issue: No ]
  • Higher sensitivity detection that allow the stratification of the MRD population into 2 groups with lower and higher likelihood of relapse [ Designated as safety issue: No ]

Estimated Enrollment: 12
Study Start Date: February 2012
Estimated Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

  • To identify and characterize changes in clonal populations of B cells in children with acute lymphoblastic leukemia (ALL) at diagnosis and Day 29 of induction.
  • To define the ability of this technology to reclassify patients as minimal residual disease (MRD) positive at Day 29 of induction.
  • To determine whether more sensitive detection of MRD at Day 29 would have clinical prognostic value in children with ALL.

OUTLINE: DNA extracted from diagnostic cells are analyzed for immunoglobulin heavy chain variable region by next-generation sequencing.
