A Randomised Phase III Study to Compare Arsenic Trioxide (ATO) Combined to ATRA Versus Standard ATRA and Anthracycline-Based Chemotherapy (AIDA Regimen) for Newly Diagnosed, Non High-Risk Acute Promyelocytic Leukemia
- Arm I:
- Induction therapy: Patients receive oral tretinoin twice daily and arsenic
trioxide IV over 2 hours on days 1-60. Patients achieving hematological complete
remission go on to receive consolidation therapy.
- Consolidation therapy: Patients receive oral tretinoin twice daily on days 1-14.
Treatment with tretinoin repeats every 4 weeks for up to 7 courses. Patients also
receive arsenic trioxide IV over 2 hours on days 1-5 in weeks 1-4. Treatment with
arsenic trioxide repeats every 8 weeks for up to 4 courses.
- Arm II:
- Induction therapy: Patients receive tretinoin as in arm I induction therapy and
idarubicin IV over 20 minutes on days 2, 4, 6, and 8. Patients achieving
hematological complete remission go on to receive consolidation therapy.
- Consolidation therapy: Patients receive oral tretinoin twice daily on days 1-45,
idarubicin IV over 20 minutes on days 1-4 and day 31, and mitoxantrone
hydrochloride IV over 30 minutes on days 16-20.
Marrow samples are collected after completion of consolidation therapy and analyzed by
reverse transcriptase-PCR for molecular remission. Patients achieving molecular remission
(PML-RARa negative) go on to receive maintenance therapy.
- Maintenance therapy: Patients receive oral mercaptopurine once daily and methotrexate
intramuscularly once weekly for 3 months. Treatment with mercaptopurine and
methotrexate repeats every 3 months for 7 courses. After completion of course 1 of
mercaptopurine and methotrexate, patients receive oral tretinoin once daily on days
1-15*. Treatment with tretinoin repeats every 3 months for 6 courses.
NOTE: *Patients do not receive mercaptopurine and methotrexate during tretinoin
administration.
After completion of study therapy, patients are followed periodically for 5 years.
As of 14th September 2010, all patients needed to evaluate the primary endpoint (162
patients) have been recruited but the trial accrual continued in order to assess one
secondary outcome (QoL)."
