Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase I trial is studying the side effects and best dose of decitabine and valproic acid in treating patients with refractory or relapsed acute myeloid leukemia or previously treated chronic lymphocytic leukemia or small lymphocytic leukemia. Drugs used in chemotherapy, such as decitabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Valproic acid may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Combining decitabine with valproic acid may kill more cancer cells.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. Determine the minimally effective pharmacological dose (MEPD) of decitabine in patients with refractory or relapsed acute myeloid leukemia or with previously treated chronic lymphocytic lymphoma or small lymphocytic lymphoma.

II. Determine the maximum tolerated dose (MTD) of valproic acid in combination with the MEPD of decitabine in these patients.

III. Determine the MEPD of valproic acid in combination with decitabine in these patients.

IV. Determine the qualitative and quantitative toxic effects of decitabine alone and in combination with valproic acid, in terms of organ specificity, time course, predictability, and reversibility in these patients.

SECONDARY OBJECTIVES:

I. Determine the therapeutic response in patients treated with decitabine alone and in combination with valproic acid.

II. Determine the pharmacokinetics of this regimen in these patients. III. Determine kinetics of methyltransferase activity and re-expression of select target genes in AML \[p15, estrogen receptor (ER), WT-1, calcitonin, MYOD1\] and in CLL/SLL \[DERMO-1, DAPK, and ID4\] known to be methylated in primary tumor cells.

IV. Correlate baseline and post-treatment changes in DNA methyltransferases (MT1, MT3a, and MT3b) expression with achievement of decitabine MEPD, toxicity, treatment resistance, and disease response in these patients.

V. Determine kinetics of HDAC enzyme inhibition and changes in the acetylation status of histones H3 or H4 following treatment with the combination. These parameters will be used to define the MEPD of the combination.

VI. Examine baseline and post-therapy changes in the "histone code' in both AML and CLL cells by assessment of the acetylation and methylation status of histones H3 and H4 lysine residues using both Western Blot and Mass Spectrometry techniques.

OUTLINE: This is a dose-escalation study. Patients are stratified according to disease (refractory or relapsed acute myeloid leukemia vs chronic lymphocytic leukemia or small lymphocytic lymphoma).

Patients receive decitabine IV over 1 hour on days 1-5 or 1-10. Treatment repeats every 28 days.

Cohorts of 6 patients receive escalating doses of decitabine until the minimally effective pharmacological dose (MEPD) is determined. The MEPD is defined as the dose at which at least 5 of 6 patients meet gene methylation criteria and no more than 1 of 6 patients experiences dose-limiting toxicity (DLT).

Once the MEPD is determined, patients receive decitabine at that dose level administered as above and oral valproic acid three times daily on days 5-21. Treatment repeats every 28 days.

Cohorts of 3-6 patients receive escalating doses of valproic acid 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 DLT. The MEPD of valproic acid is then determined using established gene methylation and toxicity criteria. Treatment continues for up to 24 months in the absence of disease progression or unacceptable toxicity.

Patients are followed for survival.

Treatment (decitabine, valproic acid)

Patients receive decitabine IV over 1 hour on days 1-5 or 1-10. Treatment repeats every 28 days.

Cohorts of 6 patients receive escalating doses of decitabine until the MEPD is determined. The MEPD is defined as the dose at which at least 5 of 6 patients meet gene methylation criteria and no more than 1 of 6 patients experiences DLT.

Once the MEPD is determined, patients receive decitabine at that dose level administered as above and oral valproic acid three times daily on days 5-21. Treatment repeats every 28 days.

Cohorts of 3-6 patients receive escalating doses of valproic acid until the MTD is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience DLT. The MEPD of valproic acid is then determined using established gene methylation and toxicity criteria.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients with AML (Stratum I) or CLL/SLL (Stratum II) will be enrolled
