Acute Promyelocytic Leukaemia APML4 Protocol
Scientific title
APML4 Protocol: A phase II trial in patients with previously untreated acute promyelocytic leukaemia to evaluate the effect on time to molecular relapse and early death rate as a result of: (i) adding arsenic trioxide to all-trans retinoic acid and idarubicin for remission induction, (ii) adding arsenic trioxide to all-trans retinoic acid as consolidation, (iii) the obligatory use of prednisone (or prednisolone) and aggressive haemostatic support during induction.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A single arm phase II study of all-trans retinoic acid (ATRA), idarubicin and arsenic trioxide (As2O3) over 36 days as induction therapy for acute promyelocytic leukaemia, followed by two cycles of consolidation with ATRA and As2O3 (over 28 days and 35 days respectively). Prednisone is administered during induction for all patients. Consolidation is followed by 2 years of maintenance therapy with daily 6-mercaptopurine, once weekly methotrexate, and 2 weeks of ATRA every 3 months. Bone marrow sampling for molecular monitoring is performed after each cycle of induction and consolidation, and then every 3 months for 2 years.

Outcomes
Primary outcome [1] 202 0
1. To evaluate in a group of patients with de novo APL the effect of a chemotherapy protocol consisting of arsenic trioxide added to standard induction (ATRA plus intensive idarubicin) and two cycles of consolidation (ATRA plus As2O3) on time to molecular relapse.
Timepoint [1] 202 0

Primary outcome [2] 203 0
2. To assess the effect of obligatory use of prednisone (or prednisolone) and aggressive haemostatic support, during induction, on early death rate (defined as death within the first 30 days).
Timepoint [2] 203 0
-
Secondary outcome [1] 459 0
1. To evaluate the use of peripheral blood as an alternative to bone marrow for molecular monitoring of minimal residual leukaemia by quantitative RT-PCR.
Timepoint [1] 459 0
Over a period of 2 years.
Secondary outcome [2] 460 0
2. To assess the relation of whole blood arsenic levels to
(a) efficacy of As2O3 as measured by time to molecular relapse, and (b) development of adverse reactions to the treatment regimen (during induction and consolidation).
Timepoint [2] 460 0
During induction and consolidation.
Secondary outcome [3] 461 0
3. To assess the impact of the GST-1 polymorphic status of individual patients on whole blood arsenic levels, as well as on efficacy and safety of As2O3.
Timepoint [3] 461 0
During induction and consolidation.
Secondary outcome [4] 462 0
4. To evaluate the effect of the chemotherapy protocol on complete remission rate (after induction and consolidation), time to relapse, and overall survival.
Timepoint [4] 462 0
At 2-5 years).
Secondary outcome [5] 463 0
5. To evaluate fertility before and at various times after the chemotherapy protocol.
Timepoint [5] 463 0
Every 12 months after maintenance is commenced until fertility status is clarified.

Eligibility
Key inclusion criteria
1. Morphological diagnosis of APL, either classical FAB-M3 or variant FAB-M3v. The leukaemia must have occurred de novo, with no previous history of preleukaemia, myelodysplasia, or myeloproliferative disorder. 2. Demonstration of PML-RARA fusion transcripts by reverse transcriptase-polymerase chain reaction (RT-PCR). 3. ECOG performance status 0-3. 4. Absence of previous history of serious cardiac, pulmonary, hepatic or renal disease, and absence of history of grand mal seizures. A serum creatinine >200umol/L or serum bilirubin >50umol/L precludes entry into the study, unless medically correctable. 5. A left ventricular ejection fraction of at least 50% as demonstrated by gated heart pool scan (preferably) or cardiac ultrasound. 6. ECG showing sinus rhythm and Q-Tc interval <500msec. Prolongation of Q-Tc due to medication or electrolyte disturbance must be corrected before registration. 7. No previous treatment for APL, or history of cancer (other than basal cell skin cancer, or carcinoma of cervix in situ). 8. No contra-indication to use of any of the study drugs. 9. A negative pregnancy test in females of child-bearing age. 10. Written informed consent
