The proposed study is based on our observation of paradoxical tumor regression after rejection of the donor graft in conjunction with the results of our murine experiments. We hypothesize that clinically meaningful responses can be achieved in patients with advanced malignancies with a transplant strategy using nonmyeloablative conditioning and related mismatched donor stem cell transplant where the intention will be to initially achieve mixed chimerism which will be followed by recipient lymphocyte infusion (RLI) in an attempt to deliberately reject the donor graft. This will lead to the development of novel transplant strategies for achieving antitumor effects without the risk of graft versus host disease (GVHD). This proposed protocol is a Pilot Study that will evaluate the safety of this outpatient transplant strategy, i.e., establishment of initial mixed chimerism followed by RLI for donor graft rejection, in patients with advanced lymphomas, and multiple myeloma.

In addition, because RLI have been reported to reverse ongoing GVHD, this approach might potentially reverse GVHD while achieving antitumor responses if this complication unexpectedly occurs.

Primary Outcome Measures:
  • To determine the safety at ≤100 days of a non myeloablative mismatched related HCT when followed by recipient leukocyte infusion to induce deliberate rejection of the donor graft. [ Time Frame: 100 days post transplant ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To evaluate the incidence of acute and chronic GVHD [ Time Frame: Up to 2 years post transplant ] [ Designated as safety issue: Yes ]
  • To evaluate the incidence of loss of donor grafts [ Time Frame: Up to 2 years post transplant ] [ Designated as safety issue: Yes ]
  • To evaluate progression-free and overall survival [ Time Frame: Up to 2 years post transplant ] [ Designated as safety issue: Yes ]
  • To evaluate antitumor responses following this transplant strategy [ Time Frame: Up to 2 years post transplant ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Active Comparator: Fludarabine
The patients in this cohort will receive fludarabine 30 mg/m2/day on days -4 to -2 and 200 cGy TBI on day 0.
Other: Fludarabine and total body irradiation
The patients in the second cohort will receive fludarabine 30 mg/m2/day on days -4 to -2 and 200 cGy TBI on day 0.
Active Comparator: TBI only
Patients will be given 200 centiGray (cGy) total body irradiation (TBI) in one fraction. TBI will be given on day 0, 4 to 6 hours prior to HCT.
Radiation: Total body irradiation
Patients will receive 200 cGy TBI on day 0,4-6 hours prior to HCT.


Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients with chemorefractory non-Hodgkin's or Hodgkin's lymphoma or multiple myeloma.

    Criteria for consideration of enrollment will include:

    1. primary refractory or refractory relapsed disease for which autologous HCT is unlikely to be beneficial;
    2. relapse after autologous HCT
    3. ineligibility for standard myeloablative or nonmyeloablative allo-HCT because of either lack of a donor or patient considerations
  2. Non Hodgkin's lymphoma, or Hodgkin's lymphoma: primary refractory or refractory relapse
  3. Multiple myeloma; primary refractory or refractory relapse
  4. Patients with the above malignancies who have had a previous autologous or allogeneic bone marrow or stem cell transplant.
  5. An estimated disease-free survival of less than one year.
  6. Age 18 to age < 75 years
  7. ECOG performance status of 0, 1, or 2.

Exclusion Criteria:

  1. Patients whose life expectancy is limited by diseases other than their malignancy
  2. Patients who have a 5/6 or better matched related donor or a 4/6 or better umbilical cord blood donor and who are medically eligible for conventional myeloablative or non-myeloablative transplant will be excluded
  3. Cardiac disease: symptomatic congestive heart failure or RVG or echocardiogram determined LVEF ogf< 30%, active angina pectoris or uncontrolled hypertension
  4. Pulmonary disease: severe chronic obstructive lung disease, or symptomatic restrictive lung disease, or corrected DLCO < 40% of predicted
  5. Renal disease: serum creatinine > 3.0 mg/dl.
  6. Hepatic disease: serum bilirubin > 3.0 mg/dl or alkaline phosphatase, SGOT or SGPT > 3 x ULN
  7. Neurologic disease: symptomatic leukoencephalopathy, active CNS malignancy or other neuropsychiatric abnormalities believed to preclude transplantation (pervious CNS malignancy presently in CR is not an exclusion)
  8. Uncontrolled infection.
  9. Recipient leukocyte infusion (RLI) might involve the infusion of circulating tumor cells to the patients. To minimize this risk patients who have evidence of circulating tumor cells by light microscopy and flow cytometry will be excluded
  10. Patients with acute leukemia will be excluded because they will likely have much greater circulating tumor burden, which would increase the risk of infusion of clonal tumor cells
