Valproic Acid in Treating Patients With Previously Treated Non-Hodgkin Lymphoma, Hodgkin Lymphoma, or Chronic Lymphocytic Leukemia

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

RATIONALE: Valproic acid may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. It may also help cancer cells become more like normal cells, and grow and spread more slowly.

PURPOSE: This phase II trial is studying how well valproic acid works in treating patients with previously treated non-Hodgkin Lymphoma, Hodgkin lymphoma, or chronic lymphocytic leukemia.

Primary Outcome Measures:
  • Response to therapy (complete response, partial response, or stable disease)

Secondary Outcome Measures:
  • Length of response
  • Time to treatment failure
  • Survival duration

Estimated Enrollment: 52
Study Start Date: August 2009
Estimated Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Detailed Description:


  • To determine if valproic acid has a response rate of ≥ 20% in patients with previously treated relapsed or refractory non-Hodgkin lymphoma, Hodgkin lymphoma, or chronic lymphocytic leukemia.
  • To determine if treatment with valproic acid leads to measurable levels of histone acetylation in peripheral blood.

OUTLINE: Patients are stratified according to disease diagnosis (indolent non-Hodgkin lymphoma [NHL] vs. aggressive NHL and Hodgkin lymphoma). Valproic acid doses are adjusted until therapeutic level is achieved.

Patients receive oral valproic acid daily for 3 weeks. Treatment repeats every 3 weeks for at least 2 courses and up to 2 years in the absence of disease progression or unacceptable toxicity.

Blood samples are collected periodically. Samples are analyzed for valproic acid levels; and hyperacetylation (caused by the valproic acid N-terminals of the histones H3 and H4) via western blot.
