Acute Promyelocytic Leukemia With PML-RARA | Drug: Arsenic Trioxide Drug: Gemtuzumab Ozogamicin Other: Laboratory Biomarker Analysis Drug: Tretinoin | Phase 2 |
PRIMARY OBJECTIVES:
I. Assess whether a combination of all-trans retinoic acid (ATRA [tretinoin]), and arsenic trioxide (ATO) can produce long-term event-free survival in patients with low-risk untreated acute promyelocytic leukemia (APL).
II. Assess whether administration of gemtuzumab ozogamicin (GO) at the diagnosis in patients with high-risk APL (white blood cell [WBC] > 10,000) and if the WBC rises to > 10,000 after start of treatment (in patients with low-risk disease) will improve complete response (CR) rate without increasing toxicity in high-risk untreated APL.
OUTLINE:
INDUCTION: Patients receive tretinoin orally (PO) twice daily (BID), arsenic trioxide intravenously (IV) over 1-2 hours daily, and gemtuzumab ozogamicin IV over 2 hours once at weeks 1-4.
CONSOLIDATION: Patients achieving CR receive arsenic trioxide IV 5 days per week during weeks 1-4, 9-12, 17-20, and 25-28 and tretinoin PO BID for 2 weeks on and 2 weeks off. Treatment repeats every 8 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 6-12 months.

Ages Eligible for Study: | 10 Years and older (Child, Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- A diagnosis of APL based on the presence of the PML-RAR-alpha fusion gene by cytogenetics, polymerase chain reaction (PCR), or POD test
- Ability to understand and the willingness to sign a written informed consent document indicating that they are aware of the investigational nature of the study
- Patients in whom therapy for APL was initiated on an emergent basis are eligible (patients may have already started treatment with ATRA, ATO, and/or one dose of idarubicin due to the urgency to start therapy early)
- Women of child-bearing potential must have a negative serum pregnancy test at screening; in addition to having a negative pregnancy test confirmed at screening, all female participants of childbearing potential must have a negative pregnancy test confirmed within 48 hours prior to dosing with the study drug
- All sexually active subjects (males and females of child-bearing potential) agree to use 2 effective methods of contraception for the duration of the study
Exclusion Criteria:
- Fridericia corrected QT (QTcF) interval on the electrocardiogram (EKG) greater than 480 milliseconds
- Patients with creatinine > 2.5 times upper limit of normal unless felt to be related the underlying leukemia by the treating physician or hemolysis or Gilbert's disease
- Patients with total bilirubin >= 2.0 times upper limit of normal unless felt to be related the underlying leukemia by the treating physician or hemolysis or Gilbert's disease
- Patients with alanine aminotransferase (ALT)/aspartate aminotransferase (AST) > 3 times upper limit of normal unless felt to be related the underlying leukemia by the treating physician or hemolysis or Gilbert's disease
