Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Current protocols have incorporated i.v.-ATO in the treatment of newly-diagnosed APL \[11-15\]. For regimens comprising oral-ATO, ATRA and chemotherapy, 5-year OS in excess of 90% is achieved \[11-15\].
The investigators have also published long-term data showing the use of oral-ATO is highly effective and safe in the relapsed and frontline settings \[16,17\].
In this study, the investigators evaluate the use of oral-ATO and ATRA based induction regimens in newly diagnosed patients with APL with no of minimal chemotherapy in a prospective multicentre phase 2 study.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Four weeks after the completion of induction phase, all patients, regardless of initial WBC, will receive two cycles of chemotherapy-free AAA consolidation (14 days every 28 days).
Four weeks after completion of consolidation, all patients will receive 12 cycles of chemotherapy-free AAA maintenance (14 days every 8 week).
Molecular monitoring monitoring with RQ-PCR or ddPCR for PML-RARA will be performed during every 4 weeks during consolidation, every 8 weeks during maintenance, and every 3 months for 24 months after completion of maintenance.

Study Groups

Oral arsenic trioxide, all-trans-retinoic acid, ascorbic acid (AAA)
Induction: Oral arsenic trioxide 10mg daily (0.16mg/kg/day in patients \< 18 years-old, all-trans retinoic acid (ATRA) \[45mg/m\^2 (25mg/m\^2 per day in patients \< 18 years-old) in 2 divided doses) and ascorbic acid 1g daily (15mg/kg/day in patients \< 18 years-old) for 42 days Consolidation: Oral arsenic trioxide daily, ATRA, and ascorbic acid daily for 14 days every 28 days for 2 cycles.
Maintenance: Oral arsenic trioxide, ATRA and ascorbic acid daily for 2 weeks every 8 weeks for a total of 2 years (i.e. for 12 cycles in total).
Oral Arsenic Trioxide Formulation
Patients will be recruited to oral arsenic trioxide, all-trans-retinoic acid, ascorbic acid (AAA) based-induction for 42 days. Daunorubicin or idarubicin will only be used during induction in patients \<65 with presenting white blood cell count (WBC) ≥ 10 x 10\^9/L. In patients not receiving daunorubicin, hydroxyurea if WBC ≥ 5 x 10\^9/L within the first 14 days of induction. A reassessment bone marrow aspirate will be performed on day 28 of induction for assessment of morphologic remission.
Four weeks after the completion of induction phase, all patients, regardless of initial WBC, will receive two cycles of chemotherapy-free AAA consolidation (14 days every 28 days).
Four weeks after completion of consolidation, all patients will receive 12 cycles of chemotherapy-free AAA maintenance (14 days every 8 week).
