Alternate Title

Decitabine, Doxorubicin, and Cyclophosphamide in Treating Children With Relapsed or Refractory Solid Tumors or Neuroblastoma

Basic Trial Information

Objectives

Primary

1. Determine the maximum tolerated dose of decitabine in combination with doxorubicin and cyclophosphamide in children with relapsed or refractory solid tumors or neuroblastoma.
2. Determine the toxic effects of this regimen in these patients.
3. Determine whether decitabine induces tumor caspase-8 demethylation and expression in these patients.

Secondary

1. Determine the pharmacokinetics of low-dose decitabine in these patients.
2. Determine the biological and clinical response in patients treated with this regimen.
3. Compare patterns of peripheral blood gene expression, using gene expression profiling, in patients before and after treatment with decitabine.

Entry Criteria

Disease Characteristics:

• Histologically confirmed diagnosis of either of the following:
  • Solid tumor (part A)
    • No lymphoma

    • Accessible disease by bone marrow aspirate or tumor biopsy
      • No laparotomy, thoracotomy, endoscopy, or craniotomy for biopsy

• No concurrent immunotherapy
• No concurrent biologic therapy
• No concurrent epoetin alfa

Chemotherapy

• Recovered from prior chemotherapy
• More than 2 weeks since prior myelosuppressive chemotherapy (6 weeks for nitrosoureas)

• No concurrent hydroxyurea

Endocrine therapy

• Not specified

Radiotherapy

• Not specified

Other

• No other concurrent anticancer therapy

Renal

• Creatinine based on age as follows:
  • ≤ 0.8 mg/dL (5 years of age and under)
  • ≤ 1.0 mg/dL (6 to 10 years of age)
  • ≤ 1.2 mg/dL (11 to 15 years of age)
  • ≤ 1.5 mg/dL (16 to 21 years of age)

  OR

• Creatinine clearance or radioisotope glomerular filtration rate ≥ 70 mL/min
• No significant renal dysfunction that would compromise the tolerability of decitabine or interfere with study procedures or results

Cardiovascular

• Shortening fraction ≥ 28% by echocardiogram

  OR

• Ejection fraction of ≥ 45% by MUGA

Pulmonary

• No significant pulmonary dysfunction that would compromise the tolerability of decitabine or interfere with study procedures or results

Other

• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception
• No prior allergic reaction attributed to compounds of similar chemical or biological composition to agents used in this study
• No uncontrolled serious infection
• No significant end-organ dysfunction that would compromise the tolerability of decitabine or interfere with study procedures or results

Expected Enrollment

A total of 15-21 patients will be accrued for this study within 1-2 years.

Outcomes

Toxicity

Caspase-8 expression

Outline

This is a multicenter, dose-escalation study of decitabine.

• Part A (solid tumor patients): Patients receive decitabine IV over 1 hour on days 0-6 and doxorubicin IV over 15 minutes and cyclophosphamide IV over 1 hour on day 7. Patients then receive filgrastim (G-CSF) subcutaneously (SC) beginning on day 8 and continuing until blood counts recover OR pegfilgrastim SC once on day 8 or 9*. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

  Cohorts of 3-6 patients receive escalating doses of decitabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

   [Note: *For patients > 45 kg]

• Part B (neuroblastoma patients): Once the MTD is determined for part A, patients are treated as in part A at the MTD .

Patients are followed at 30 days.
