Brief Summary:
Mantle Cell Lymphoma is a sub-type of Non-Hodgkin's Lymphoma which is generally considered incurable with current therapy. Our goal is to accrue 59 patients who receive an autologous vaccine against their individual lymphoma after undergoing stem cell transplantation. Our hope is that vaccination will prolong the time which patients will stay in remission from their disease.

Arm Intervention/treatment
Experimental: "CpG-MCL" vaccine
Patients will initially receive three 'priming' CpG-MCL vaccinations in 21 days at 4-7 day intervals, followed by collection of "primed" T-Cells. Subsequently, within 72 hours of autologous hematopoetic cell transplant (AHCT)(standard of care procedure), the patient will receive his/her CpG-MCL vaccine and reinfusion of primed T cells ("immunotransplant"). At >/= 3 months after AHCT, when medically feasible, the patient will receive the final CpG-MCL vaccine. Regular follow-up research analysis of molecular residual disease will continue for 3 years or until disease progression.

Primary Outcome Measures :
  1. The primary endpoint of the trial is freedom from molecular residual disease (MRD) at the landmark of one-year post-transplant. [ Time Frame: Samples for MRD analysis are collected every 3 months until one-year post transplant. ]
    After the one-year mark, samples for MRD analysis will be collected every 6 months for 3 years or until disease progression.


Secondary Outcome Measures :
  1. Secondary objectives are Time To Clinical Progression (TTP), and evaluation of anti-tumor immune responses after vaccination, and after immunotransplant. progression-free survival. [ Time Frame: 1 year, 3 years, 5 years ]

Criteria

Inclusion Criteria (at time of enrollment):

  • Patients must be newly diagnosed with mantle cell lymphoma, have an accessible disease site for excisional biopsy or have sufficient peripheral blood tumor to leukapherese at least 1.5 x 109 lymphoma cells in a single session.
  • By standard clinical criteria, be medically appropriate to receive rituximab and standard induction chemotherapy and high-dose chemotherapy with AHCT.
  • Patients must be HIV negative.
  • ECOG performance status 0, 1, or 2 or Karnofsky performance scale 50-100%.

  • Patients with severe psychological or medical illness.
  • Pregnant or lactating women.
  • At the discretion of the principal investigator if he/she feels that the patient is unable to safely complete the study. Specifically, patients must be considered medically eligible to undergo standard high dose chemotherapy and autologous stem cell transplantation.
