Arsenic trioxide & ATRA

Regimen variant #1, 0.15/45

Study	Years of enrollment	Evidence	Comparator	Comparative Efficacy
Estey et al. 2005	2002-2005	Phase 2
Ravandi et al. 2008	2002-2007	Phase 2
Lo-Coco et al. 2013 (GIMEMA/DSIL APL0406)	2007-2013	Phase 3 (E-RT-switch-ooc)	ATRA & Idarubicin	Seems to have superior OS1 (HR 0.15, 95% CI 0.03-0.67)

¹Reported efficacy for GIMEMA/DSIL APL0406 is based on the 2019 update.
Note: In Estey et al. 2005, arsenic trioxide was started on day 11, but was later modified to start on day 1 after a death due to hyperleukocytosis and intracranial hemorrhage during induction. GIMEMA/DSIL APL0406: Patients with low- or intermediate-risk APL (white blood cell count at presentation less than or equal to 10 x 10⁹/L) were eligible.

Targeted therapy

• Arsenic trioxide (Trisenox) 0.15 mg/kg IV over 2 hours once per day, starting on day 1 and continuing until hematologic complete remission or maximum of 60 days.
• All-trans retinoic acid (ATRA) 22.5 mg/m² PO twice per day, starting on day 1 and continuing until hematologic complete remission or maximum of 60 days (GIMEMA/DSIL APL0406) or 90 days (Estey et al. 2005 & Ravandi et al. 2008).

Supportive therapy

• As described in GIMEMA/DSIL APL0406:
• Prednisone (Sterapred) 0.5 mg/kg PO once per day from days 1 until the end of induction or the onset of differentiation syndrome
  • Patients who develop differentiation syndrome then received: Dexamethasone (Decadron) 10 mg IV every 12 hours until signs and symptoms resolve, and for a minimum of 3 days
• Hemostatic support: Transfusions to keep platelet count greater than 30 x 10⁹/L for the first 10 days of induction and greater than 20 x 10⁹/L for the remainder of induction
• Hydroxyurea (Hydrea) by the following criteria:
  • Patients with WBC count greater than 10 x 10⁹/L and less than 50 x 10⁹/L after the start of therapy: 500 mg PO four times per day, given until WBC count is less than 10 x 10⁹/L
  • Patients with WBC count greater than 50 x 10⁹/L after the start of therapy: 1000 mg PO four times per day, given until WBC count is less than 10 x 10⁹/L

Up to 60- to 90-day course

Subsequent treatment

• Arsenic trioxide & ATRA consolidation

Regimen variant #2, 0.16/25

Study	Years of enrollment	Evidence	Comparator	Comparative Efficacy
Shen et al. 2004	2001-2003	Randomized (E-esc)	1. Arsenic trioxide 2. ATRA	Seems to have superior DFS
Zhu et al. 2013	2007-2011	Phase 3 (C)	Realgar-Indigo naturalis formula	Non-inferior DFS

Targeted therapy

• Arsenic trioxide (Trisenox) 0.16 mg/kg IV once per day, starting day 1 and continuing until remission
• All-trans retinoic acid (ATRA) 12.5 mg/m² PO twice per day, starting day 1 and continuing until remission or maximum of 90 days.

Up to 90-day course

Subsequent treatment

• Patients achieving CR: chemotherapy-based consolidation and maintenance. These details are available in the original paper but are omitted here.

Regimen variant #3, 0.3/45

Study	Years of enrollment	Evidence	Comparator	Comparative Efficacy	Comparative Toxicity
Burnett et al. 2015 (UK NCRI AML17)	2009-2013	Phase 3 (E-switch-ooc)	ATRA & Idarubicin		Did not meet primary endpoint of QoL

Note: this is an experimental arm that did not meet its primary endpoint; included here because other variants of this regimen have demonstrated comparative superiority.

Targeted therapy

• Arsenic trioxide (Trisenox) 0.3 mg/kg IV once per day on days 1 to 5, then 0.25 mg/kg IV twice per week on weeks 2 to 8

• Methylprednisolone (Solumedrol) by the following study-specific criteria:
  • Estey et al. 2005: 20 mg PO once per day for 10 days to decrease risk of differentiation syndrome
  • Ravandi et al. 2008: 50 mg PO once per day for 5 days to decrease risk of differentiation syndrome

28-day course

Note: These obsolete regimens are here for historical reference; ATRA is no longer used as monotherapy for induction; some patients in EAPLG APL 91 received concurrent chemotherapy (see paper for details)

Targeted therapy

• All-trans retinoic acid (ATRA) 22.5 mg/m² PO twice per day, starting day 1 and continuing until remission or maximum of 90 days

Subsequent treatment

• EAPLG APL 91: Cytarabine & daunorubicin consolidation

This consolidation arm was a randomization for younger (less than 60), low-risk (WBC count less than 10 x 10⁹/L) patients. Low-risk (WBC count less than 10 x 10⁹/L) older (greater than 60) patients received this regimen in a non-randomized fashion.

Preceding treatment

• ATRA & daunorubicin induction

Chemotherapy

• Daunorubicin (Cerubidine) as follows:
  • Cycle 1: 60 mg/m² IV once per day on days 1 to 3
  • Cycle 2: 45 mg/m² IV once per day on days 1 to 3

Subsequent treatment
