Brief Summary:
This phase II trial is studying how well PXD101 works in treating patients with relapsed or refractory aggressive B-cell non-Hodgkin's lymphoma. PXD101 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer.

Recurrent Adult Burkitt Lymphoma Recurrent Adult Diffuse Large Cell Lymphoma Drug: belinostat Phase 2

Detailed Description:


I. Evaluate response rate in patients with relapsed or refractory aggressive B-cell non-Hodgkin's lymphoma treated with PXD101.


I. Determine the toxicity of this drug in these patients. II. Estimate the 6-month progression-free survival rate in patients treated with this drug.


I. Determine the major histocompatability complex of class II proteins (HLA-DR, -DP, -DQ), TUNEL, and CD8 infiltration status, by immunochemistry on paired pre- and post-treatment tumor samples, in the first 20 patients enrolled.

II. Measure CIITA and HLA-DR mRNA expression using quantitative reverse transcriptase-polymerase chain reaction and determine, preliminarily, the associations of these markers with progression-free survival.

III. Evaluate paired pre- and post-treatment peripheral blood mononuclear cells from patients for histone acetylation status and determine correlation with findings from duplicate experiments on pre- and post-needle core biopsies.

OUTLINE: This is a multicenter study.

Patients receive PXD101 IV over 30 minutes on days 1-5. Treatment repeats every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

Needle core biopsies and peripheral blood mononuclear cells are obtained from the first 20 patients pre- and post-treatment for biomarker correlative studies.

After completion of study treatment, patients are followed every 3-6 months for up to 3 years.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 22 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Study of PXD101 (NSC-726630) in Relapsed and Refractory Aggressive B-Cell Lymphomas
Study Start Date : January 2006
Actual Primary Completion Date : January 2010
Actual Study Completion Date : August 2010

Arm Intervention/treatment
Experimental: Arm I

Patients will receive an infusion of PXD101 once a day for 5 days. Treatment may repeat every 3 weeks for up to 2 years. Some patients will also undergo core biopsy and blood collection for laboratory studies before and after treatment.

After finishing treatment, patients will be evaluated every 3-6 months for up to 3 years.

Drug: belinostat
Given IV
Other Name: PXD101

Primary Outcome Measures :
  1. Assess Number of Patients Who Achieve Confirmed and Unconfirmed Complete Response (CR) or Partial Response (PR) [ Time Frame: assessed at week 8, and every 3 months for 3 years ]
    Complete Response(CR) is a complete disappearance of all disease with the exception of nodes. No new lesions. previously enlarged organs must have regressed and not be palpable. Bone marrow(BM) must be negative if positive at baseline. Normalization of markers. CR Unconfirmed (CRU) does not qualify for CR above, due to a residual nodal mass or an indeterminate BM. Partial Response(PR) is a 50% decrease in the SPD for up to 6 identified dominant lesions, including spleenic and hepatic nodules from baseline. No new lesions and no increase in the size of liver, spleen or other nodes.

Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: assessed every 3 months for 3 years ]
    Measured from time of registration to death, or last contact date

  2. Progression-free Survival [ Time Frame: assessed at week 8, then every 3 months for 3 years ]
    Measured from date of registration to time of first documentation of progression or death, or last contact date. Progression is defined as a 50% increase in sum of products of greatest diameters (SPD) of target measurable lesions over the smallest sum observed (over baseline if no decrease during therapy) using the same techniques as baseline; appearance of a new lesion/site; unequivocal progression of non-measurable disease in the opinion of the treating physician; death due to disease without prior documentation of progression.
