RATIONALE: DNA analysis of blood and tissue samples may help doctors predict how well patients will respond to treatment. It may also help doctors learn more about how gemtuzumab ozogamicin works in the body.

PURPOSE: This research study is looking at gemtuzumab ozogamicin in DNA samples from patients with acute myeloid leukemia treated on COG-AAML0531.

Primary Outcome Measures:
  • Genetic changes in CD33 impact outcome of gemtuzumab ozogamicin-based therapy [ Designated as safety issue: No ]

Estimated Enrollment: 1000
Study Start Date: July 2011
Estimated Primary Completion Date: January 2100 (Final data collection date for primary outcome measure)
Detailed Description:


  • To genotype the genomic DNA from acute myeloid leukemia (AML) patients treated on COG-AAML0531 clinical trial for CD33 (and PgP and SOC3) single nucleotide polymorphisms (SNPs).

OUTLINE: Archived DNA samples are analyzed for single nucleotide polymorphisms in CD33, PgP, and SOC3 genes by Sequenome platform. Results are then compared with patients clinical outcomes, including minimal-residual disease levels post induction I (chemotherapy and gemtuzumab ozogamicin), complete remission rates, refractory disease with various levels of bone marrow blasts, development of CNS/persistent disease, event-free survival, overall survival, and toxicity.
