Outcome Measures

Primary Outcomes (3)

  • Purity of ex vivo depleted regulatory T cells prior to autologous stem cell transplant (arm 3 only)

    Percentage of CD4+CD25+ regulatory T cells following ex vivo depletion in arm 3 will be analyzed by flow cytometry and compared to a pre-CD25-depletion sample. The depletion of CD25+ cells among the entire CD4+ population is expected to reach 80% efficiency.

    1-3 days

  • Timing and duration of regulatory T cell depletion and recovery following autologous stem cell transplant

    Timing and duration of regulatory T cell depletion and recovery following in vivo or ex vivo (arms 2 and 3) CD25+ T cell depletion will be performed at pre-defined timepoints prior to and following autologous stem cell transplant by flow cytometry on peripheral blood samples and directly compared to the percentages of regulatory T cells (CD4+CD25+FoxP3+ or CD4+CD25+CD127-) present at the same timepoints in patients enrolled onto arm 1 in which no regulatory T cell depletion is performed.

    180 days

  • Incidence of autologous graft-versus-host disease following in vivo or ex vivo regulatory T cell depletion

    The indicence of autologous graft-versus-host disease, as assessed by the development of skin rash, diarrhea and/or liver function test abnormalities consistent with autologous graft-versus-host disease following CD25+ T cell depletion and autologous stem cell transplant compared with the incidence of autologous graft-versus-host disease in patients enrolled onto arm 1 in which no regulatory T cell depletion is performed.

    180 days

Secondary Outcomes (2)

  • Kinetics of recovery of peripheral blood cellular elements

    180 days

  • Number of patients that experience a complete response following autologous stem cell transplant based upon the assigned study arm using International Myeloma Working Group definitions

    100 days

Study Arms (3)

Standard ASCT (Grp 1)

ACTIVE COMPARATOR

Standard autologous stem cell transplantation (ASCT)

Drug: G-CSFDrug: PlerixaforProcedure: ApheresisDrug: MelphalanProcedure: Stem cell re-infusion

Depletion of T-cells after ASCT (Grp 2)

EXPERIMENTAL

Standard ASCT followed by treatment with basiliximab to remove certain immune cells (called regulatory T-cells or Tregs) from the blood

Drug: G-CSFDrug: PlerixaforProcedure: ApheresisDrug: MelphalanProcedure: Stem cell re-infusionDrug: Basiliximab

Depletion of T-cells before ASCT(Grp 3)

EXPERIMENTAL

Blood collected for an ASCT will be processed using a special cell sorting machine (CliniMACS device) to remove Treg cells before the stem cells are infused back into the body during stem cell transplant.

Drug: G-CSFDrug: PlerixaforProcedure: ApheresisDrug: MelphalanProcedure: Stem cell re-infusionDevice: CliniMACS CD25 microbeads and cell sorter

Interventions

G-CSFDRUG

G-CSF will be self-administered shot daily for 4 days pre-transplant. Up to 8 doses of G-CSF may be given. G-CSF will also be administered once daily under the skin beginning 5 days after your stem cell infusion until your white blood cell count is high enough

Depletion of T-cells after ASCT (Grp 2)Depletion of T-cells before ASCT(Grp 3)Standard ASCT (Grp 1)

Plerixafor (self-administered shot)prior to the beginning of the stem cell collection. Up to 4 doses of plerixafor may be given.

ApheresisPROCEDURE

Stem cell collection begins on day 5 and can last up to 3 days depending on the number collected.

Depletion of T-cells after ASCT (Grp 2)Depletion of T-cells before ASCT(Grp 3)Standard ASCT (Grp 1)

Melphalan chemotherapy 100mg/m2 for 2 days after your admission into the hospital for your ASCT procedure.

Also known as: Alkeran
Depletion of T-cells after ASCT (Grp 2)Depletion of T-cells before ASCT(Grp 3)Standard ASCT (Grp 1)

Stem cells are thawed and reinfused back into the body via a catheter in the vein.

Depletion of T-cells after ASCT (Grp 2)Depletion of T-cells before ASCT(Grp 3)Standard ASCT (Grp 1)

Basiliximab (20mg) given by IV infusion (through the vein) 20-30 minutes the day after ASCT.

Also known as: Simulect
Depletion of T-cells after ASCT (Grp 2)

The stem cells collected during apheresis will be counted and treated with CD25 microbeads and processed by a special device called a CliniMACs machine which removes the regulatory T cells from you stem cell product.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • HIV Negative.
  • No active Hepatitis B or C.
  • Patients must be able to provide written informed, consent.

You may not qualify if:

  • Pregnant or nursing women. Women of child-bearing age must be tested for pregnancy.
  • Use of systemic immunosuppressive medications, including corticosteroids, tacrolimus, mycophenolate mofetil, sirolimus or cyclosporine A.
  • Psychiatric illness which may make compliance to the clinical protocol unmanageable or which may compromise the ability of the patient to give informed consent.
