Masking: None (Open Label)
Primary Purpose: Treatment
|Official Title:||A Phase I Study of Decitabine in Combination With Valproic Acid in Patients With Selected Hematologic Malignancies|
- MEPD of single agent decitabine [ Time Frame: 10 days ]
- MTD of the combination of valproic acid with the MEPD of decitabine [ Time Frame: Up to 21 days ]
- MEPD of valproic acid in combination with decitabine [ Time Frame: Up to 29 days ]
- Qualitative and quantitative toxicities of single agent decitabine alone and in combination with valproic acid in regard to organ specificity, time course, predictability, and reversibility [ Time Frame: Up to 24 months ]
|Study Start Date:||February 2004|
|Primary Completion Date:||May 2011 (Final data collection date for primary outcome measure)|
Experimental: 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. Treatment continues for up to 24 months in the absence of disease progression or unacceptable toxicity.
