Beyond A CR - Postinduction Options
With A Compendium Of Articles On Critical Choices In Aml Today
Achieving A CR
SIGNIFICANTLY LESS RESISTANT DISEASE OCCURS WITH IDAMYCIN IN THE REGIMEN
- Less resistant disease due to persistent blasts means greater responses
- Greater responses lead to more postinduction options for patients
SIGNIFICANTLY FEWER PATIENTS HAVE HAD PERSISTENT BLASTS* ON THE IDAMYCIN ARM IN EACH STUDY
|
|
Abbreviations: IDA, idarubicin; DNR, daunorubicin
*Of evaluable or assessable patients
|
SIGNIFICANTLY HIGHER CR RATES OCCUR WITH IDAMYCIN IN THE REGIMEN**
- Consistently more CRs achieved after the first course of therapy
- More durable therapy with consistently longer CRs Greater responses, more opportunity for postinduction options
**In two of three US studies.
CR RATES CONSISTENTLY HIGHER ON THE IDAMYCIN ARM IN EACH STUDY

ACHIEVING A CR WITH MINIMAL RESISTANT DISEASE — ESSENTIAL FOR POSTINDUCTION OPTIONS
Allogeneic Transplantation
- Most common reasons that patients aged <= 40 years with an HLA match did NOT undergo BMT were primary refractory disease and short complete remission (< 3 mo).[4]
Autologous Transplantation
- Purging autologous bone marrow using monoclonal antibodies and cytotoxic agents can help achieve long-term DFS in many AML patients.[5]
Immunotherapy
- "IL-2 appears to represent a therapeutic option for AML patients with limited/minimal residual disease."[6]
ACHIEVING A CR AND BEYOND — IN AML
- Significantly fewer patients with resistant disease
- Significantly higher complete remission rates*
- Significantly longer survival*
- Superior therapeutic profile during induction*
- And options for postinduction therapy
*In two of three US studies
TIME IS OF THE ESSENCE
