This phase II trial studies how well giving vorinostat, cladribine, and rituximab together works in treating patients with mantle cell lymphoma (MCL), chronic lymphocytic leukemia (CLL), or B cell non-Hodgkin's lymphoma (NHL) that has returned after a period of improvement. Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cladribine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Giving vorinostat together with cladribine and rituximab may kill more cancer cells.

Primary Outcome Measures:
  • Objective response rate [ Time Frame: 2 years ]
    Assessed per the revised Cheson criteria. Response definitions per revised International Working Group Response Criteria. 95% confidence interval will be provided.

  • Toxicities as assessed using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Activation of genes or miRNAs [ Time Frame: Up to 2 years ]
  • DNA methylation/histone deacetylation [ Time Frame: Baseline ]
    A logrank test will be used to compare progression-free survival (PFS) and overall survival (OS) between patients with and without DNA methylation and/or histone deacetylation. A chi-square test will be used to compare the objective response between patients with and without DNA methylation and/or histone deacetylation status.

  • Event-free survival [ Time Frame: 2 years ]
    Estimated using the Kaplan-Meier method.

  • Global and gene specific changes in transcription of mRNAs and MiRNAs [ Time Frame: Up to 2 years ]
  • Progression-free survival [ Time Frame: 2 years ]
    Estimated using the Kaplan-Meier method.

Detailed Description:


I. Determine objective response rates of the SCR regimen (vorinostat, cladribine, and rituximab) in B-cell malignancies.

II. Determine the tolerability and toxicities of the SCR regimen.


I. Evaluate progression free survival in patients treated with SCR. II. Estimate event free survival for patients treated with SCR. III. Determine the contribution (if any) of deoxyribonucleic acid (DNA) methylation/histone deacetylation to disease progression and/or response to SCR combination chemotherapy.

IV. Perform scientific correlates to determine if SCR treatment a) is associated with global and gene specific changes in transcription of messenger ribonucleic acid (mRNA)s and micro ribonucleic acid (MiRNA)s b) is acting as an inhibitor of DNA methylation c) is activating or silencing specific genes or miRNAs.


Patients receive vorinostat orally (PO) on days 1-14, cladribine intravenously (IV) over 2 hours on days 1-5, and rituximab IV on day 3 (weekly for the first course). Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 2 years and then every 6 months thereafter.
