Tretinoin and Arsenic Trioxide With or Without Gemtuzumab Ozogamicin in Treating Patients With Previously Untreated Acute Promyelocytic Leukemia

Summary

This phase II trial studies how well tretinoin and arsenic trioxide with or without gemtuzumab ozogamicin works in treating patients with previously untreated acute promyelocytic leukemia. Drugs used in chemotherapy, such as tretinoin and arsenic trioxide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotoxins, such as gemtuzumab ozogamicin, may find certain cancer cells and kill them without harming normal cells. Giving tretinoin and arsenic trioxide together with gemtuzumab ozogamicin may kill more cancer cells.

Eligibility

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
