Arsenic Trioxide and Gemtuzumab Ozogamicin in Treating Patients With Advanced Myelodysplastic Syndromes

• Status: Completed
• Trial end date: 2010-11-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide and gemtuzumab ozogamicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells.

PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with gemtuzumab ozogamicin works in treating patients with advanced myelodysplastic syndromes.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: The Cleveland Clinic
• Collaborators: National Cancer Institute (NCI); University of Michigan
• Treatments: Arsenic Trioxide; Gemtuzumab

Criteria

DISEASE CHARACTERISTICS:

• Diagnosis of one of the following hematologic malignancies:

• Myelodysplastic syndromes (MDS) of one of the following French-American-British (FAB) classifications:

• Refractory anemia with excess blasts (RAEB) (WHO RAEB-1)

• RAEB in transformation (RAEB-t) (RAEB-2)

• Chronic myelomonocytic leukemia (CMML) with > 5% myeloblasts (WHO CMML-2)

• International Prognostic Scoring System (IPSS) score of intermediate-2 or higher in the setting of > 5% myeloblasts

• Acute myeloid leukemia that has evolved from MDS

• Must not be a candidate for bone marrow transplantation as first-line therapy or must have declined bone marrow transplantation

PATIENT CHARACTERISTICS:

• Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2

• Life expectancy of at least 4 months

• Serum potassium ≥ 4.0 milliequivalent (mEq/dL) and serum magnesium ≥ 1.8 mg/dL (supplemental electrolytes allowed)

• Absolute corrected QT interval (QTc) interval < 460 msec

• No serious medical condition, laboratory abnormality, or psychiatric illness that, in the view of the treating physician, would place the patient at an unacceptable risk if he or she were to participate in the study or would prevent that person from giving informed consent

• Not pregnant or nursing

• Fertile patients must be willing to use adequate contraception (barrier method with spermicidal jelly, intrauterine device (IUD), or oral contraceptives)

• Negative pregnancy test

• Creatinine > 2.5 mg/dL

• serum glutamate oxaloacetate transaminase (SGOT) or serum glutamate pyruvate transaminase (SGPT) > 1.5 times upper limit of normal

• Bilirubin > 2.0 mg/dL

• No history of malignancy within the past 3 years other than MDS except basal cell or squamous cell carcinoma of the skin or carcinoma in situ of the cervix or breast

• Arsenic trioxide is contraindicated in patients who are hypersensitive to arsenic

PRIOR CONCURRENT THERAPY:

• No prior bone marrow transplantation

• Must not receive another investigational or approved therapy for MDS within 4 weeks of study enrollment, including growth factors (within 1 week of study enrollment)

• No prior arsenic trioxide or gemtuzumab ozogamicin

• No other concurrent cytotoxic drugs or investigational agents
