Vorinostat After Stem Cell Transplant in Treating Patients With High-Risk Lymphoma

Phase 1

Completed

Brief Summary: RATIONALE: Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth, and may stimulate the immune system to stop cancer cells from growing.

PURPOSE: This phase I trial is studying the side effects and best dose of vorinostat after stem cell transplant in treating patients with high-risk lymphoma.

Detailed Description: OBJECTIVES:

Primary

* To assess dose-limiting and nonhematologic toxicity of prolonged administration of vorinostat (SAHA) when administered after autologous peripheral blood stem cell transplantation in patients with high-risk lymphoma.

Secondary

* To determine, preliminarily, clinical activity by assessing the overall survival and progression-free survival.

* To evaluate the effect of vorinostat on immune reconstruction and acetylation.

* To obtain pilot data regarding an association of vorinostat with patient quality of life and inflammatory cytokine production of peripheral blood mononuclear cells.

OUTLINE: This is a dose-escalation study of vorinostat (SAHA).

Approximately 60 days after autologous hematopoietic stem cell transplantation (HSCT), patients receive oral vorinostat once daily on days 1-21. Treatment repeats every 28 days for up to 11 courses in the absence of unacceptable toxicity or disease progression.

Blood and bone marrow samples are collected periodically for laboratory correlative studies comprising immune reconstitution assays, regulatory T-cell expansion analysis, H3 and H4 acetylation by immunohistochemistry, cytokine bead array to quantify interleukin (IL)-2, IL-4, IL-5, IL-6, IL-10, tumor necrosis factor alpha and interferon gamma. Quality of life correlative studies are measured by questionnaires periodically.

After completion of study treatment, patients are followed for at least 30 days.

Primary Outcome Measures

Name	Time	Method
Safety and Tolerability of Vorinostat (SAHA) After Autologous Stem Cell Transplantation	Up to 3 years	NCI CTCAE version 3.0 was used to assess Adverse Events (AE) Grade 1=Mild AE Grade 2=Moderate AE Grade 3=Severe AE Grade 4=Life-threatening or disabling AE

Secondary Outcome Measures

Name	Time	Method
Duration of Response	Up to 5 years	Median follow up of living patients
Clinical Benefit	Up to 3 years	Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Time to Progression	Up to 3 years	Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions
