The aim of this study is to test the effect of the combination of valproate in combination with imatinib with an aim of achieving a maximal molecular response as the primary goal.
Chronic Myelogenous Leukemia
Drug: Gleevec (imatinib), valproic acid
||Endpoint Classification: Safety/Efficacy Study

Primary Purpose: Treatment
||A Phase II Study of Imatinib and Valproic Acid in Patients With CML
Primary Outcome Measures:
- To measure the effect of the combination of valproate in combination with imatinib with an aim of achieving a maximal molecular response as the primary goal. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

The aim of this study is to test the effect of the combination of valproate in combination with imatinib with an aim of achieving a maximal molecular response as the primary goal. Briefly, patients with CML who are taking imatinib and have been found to have a plateau in their level of the bcr-abl transcript will be eligible to participate in the study. Valproate will then be added to the imatinib, and subsequent bcr-abl transcripts will be monitored to see if the addition of valproate produced a further reduction. Patients will be monitored for efficacy and toxicity.
|Ages Eligible for Study:
||18 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- All patients, 18 years of age or older, with a diagnosis of CML.
- Patients must have a life expectancy of at least 12 weeks.
- Patients must have an ECOG performance status of 0-2.
- Patients must sign an informed consent.
- Patients should have adequate hepatic function with a total bilirubin < 2 mg/dl and SGOT or SGPT < two times the upper limit of normal, and adequate renal function as defined by a serum creatinine < 1.5 x upper limit of normal.
- Patients with CML in chronic phase on imatinib as first line therapy who fulfill the following criteria:
- The patient has at least two tests for quantitative reverse transcriptase polymerase chain reaction (RT-PCR) for bcr-abl (peripheral blood or bone marrow aspirate). The results of these tests should demonstrate a relative plateau in the effect of imatinib on the detected level of the transcript (i.e. there should less than a ½ log difference between the last two values). Note: Patients will be eligible if the more recent study is greater than the previous study by any value.
- The last two quantitative RT-PCR studies should be at least 3 months apart.
- The patient should have received at least 9 months of imatinib since the diagnosis of CML.
- The patient is tolerating imatinib without any grade 3 or greater toxicity.
- Pregnant women or nursing mothers are not eligible for this trial. Patients of child bearing potential must use adequate contraception.
- Patients may receive no other concurrent chemotherapy or radiation therapy during this trial.
- Patients with severe medical problems such as uncontrolled diabetes mellitus or cardiovascular disease or active infections are not eligible for this trial.
- Patients who have a hypersensitivity to valproic acid, derivatives, or any component of the formulation. Patients with hepatic disease or significant impairment, or urea cycle disorders
