Vorinostat in Treating Patients With Low-Grade Non-Hodgkin's Lymphoma
This phase II trial is studying how well vorinostat works in treating patients with relapsed or refractory indolent non-Hodgkin's lymphoma. Drugs used in chemotherapy, such as vorinostat, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vorinostat may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

- Response rate (complete remission + partial remission) [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]Exact binomial 95% confidence intervals will be provided.
- Time to progression [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]Estimated using the product-limit method of Kaplan and Meier.
- Overall survival [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]Estimated using the product-limit method of Kaplan and Meier.
- Incidence of adverse events as graded by the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0 [ Time Frame: Up to 3 years ] [ Designated as safety issue: Yes ]Recorded by type, severity, time of onset, time of resolution, and the probable association with the study regimen. Tables will be constructed to summarize the observed incidence by severity and type of toxicity.
- Change in histone acetylation by immunohistochemistry (IHC) and Western Blot (WB) [ Time Frame: Baseline to up to day 14 ] [ Designated as safety issue: No ]Histone acetylation by IHC will be scored as -, +, ++, or +++, reflecting both the intensity of staining as well as the number of cells stained; and histone acetylation by WB will recorded as the ratio of acetylated histone (measured by photodensitometry) divided by the total histone (H3 or H4), in order control for the amount of protein loaded. Analysis will be primarily descriptive, with the goal of describing baseline distributions and estimating the frequency and degree of changes from baseline.
|Study Start Date:||September 2005|
|Estimated Primary Completion Date:||December 2014 (Final data collection date for primary outcome measure)|
Experimental: Treatment (vorinostat)
Patients receive vorinostat PO BID on days 1-14. Treatment repeats every 21 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
Other Names:Other: laboratory biomarker analysis
I. To evaluate the anti-tumor activity of SAHA (vorinostat) as assessed by the objective response rate, time to progression and survival in subjects with advanced lymphoma.
II. To assess the toxicity profile of SAHA in this patient population. III. To perform correlative laboratory investigations to confirm modulation of chromatin acetylation as the biologic target and attempt to gain insight into the downstream molecular mechanisms involved in the induction of apoptosis mediated by SAHA.
Patients receive vorinostat orally (PO) twice daily (BID) on days 1-14. Treatment repeats every 21 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year and then every 6 months for 2 years.
