Tacrolimus and Mycophenolate Mofetil as Post-Grafting Immunosuppression After Conditioning With Fludarabine and Low-Dose Total Body Irradiation for Recipients of HLA-Matched or Mis-Matched Family or Unrelated Donor HCT

This protocol will evaluate Tacrolimus and MMF after conditioning with fludarabine and
low-dose TBI in patients who are not candidates for conventional allografting. A novel
approach to immunosuppression will be tested incorporating an early but extended taper of
Tacrolimus starting on day +80 or in the case of relapse. The goal is to induce early
immunity and GVT effects without compromising GVHD control. The anti-metabolite MMF will be
re-introduced on day +100 to try and induce tolerance and block chronic GVHD during the
taper of the Tacrolimus. DLI may be given in the presence of disease progression but not for
mixed chimerism as in previous protocols.

OBJECTIVES

Major Objectives A. To determine whether stable allogeneic hematopoietic engraftment can be
safely established in patients receiving a non-myeloablative allogeneic SCT from an
HLA-Identical or non-identical family donor or unrelated donors, with fludarabine and
low-dose TBI, with immunosuppression utilizing tacrolimus and MMF.

B. To evaluate the incidence of grade II-IV GVHD associated with this treatment.

C. To evaluate the engraftment when donors who are not HLA-identical family members are
utilized for allogeneic stem cell transplantation.

D. To evaluate the incidence of GVHD using three times per day MMF after unrelated donor
stem cell transplants or two times per day MMF after family donor stem cell transplant.

Minor Objectives A. To evaluate the incidence of chronic GVHD utilizing Tac/MMF with
peripheral blood stem cells from matched or mis-matched allogeneic donors.

B. To evaluate disease responses and survival after Flu/TBI allogeneic SCT.

Inclusion Criteria:

- Patients with AML, ALL, CML, CLL, myelodysplastic syndrome (MDS), NHL, Hodgkin's
disease (HD), paroxysmal nocturnal hemoglobinuria (PNH), hypoproliferative dysplasia
with or without increased blasts, or myeloma, who are at significantly higher than
usual risk for mortality from conventional myeloablative allogeneic SCT due to age or
comorbidities:

- Age ≥ to 50 years with AML or ALL in complete remission or with <18% blasts in bone
marrow

- Age ≥ to 50 years with MDS or CML.

- Age 16 to 75 years with lymphomas or myeloma, who have failed chemotherapy and are
not candidates for an autologous transplant, or who have failed a prior autologous
SCT.

- Patients of any age with CLL or low-grade NHL. Patients with CLL and low-grade NHL
need to have failed at least first-line treatment, with an alkylating agent,
fludarabine or 2-chlorodeoxyadenosine (2-CDA), or anti-CD20 monoclonal antibody
rituximab.

- Patients of any age with marrow failure

- Patients ≥60 years old will first be considered for an allogeneic stem cell
transplant from a family member and will be offered an unrelated donor transplant
only if no suitable family member, preferably an HLA-matched sibling, is available.

- Patients with hematological malignancy relapsed after prior auto transplantation.

- Patients at high-risk (>60%) of relapsing after autologous transplantation for
hematological malignancies may receive allogeneic transplant as "consolidative
immunotherapy". Diagnoses include MM, non-HL, HL, AML, ALL and MDS. Minimal duration
between auto and allo transplants is 4 weeks.

- Patients of any age with hematologic malignancies treatable by allo SCT, who, because
of pre-existing medical conditions or the disease itself (Fanconi anemia or PNH), are
considered to be at significantly increased risk for transplant toxicity using
high-dose transplantation regimens.

- Patients with metastatic renal cell carcinoma. Must have include good performance
status (Karnofsky score ≥ 60%), no active brain metastases, life expectancy of at
least 6 months, absence of bulky liver metastases. Patients will be treated on other
active disease-specific protocols when available.

- Patients with other malignant diseases treatable with allogeneic SCT may be eligible
for this protocol on a case by case basis, if approved by the principal investigator
and the BMT attending physicians group.

- Available HLA-identical, a one-antigen mis-matched sibling donor, a phenotypically
HLA-matched family member, a phenotypically matched unrelated donor, or a 9/10
matched unrelated donor.

- Age ≤ 75 years.

Exclusion Criteria:

- Patients with hematological malignancies eligible for a curative autologous SCT:
intermediate- or high-grade NHL with chemo-sensitive first relapse.

- HD with chemo-sensitive first relapse.

- Otherwise healthy patients who are eligible for a conventional myeloablative
allogeneic SCT.

- Patients with rapidly progressive intermediate or high-grade NHL, unless in minimal
disease state after the last treatment.

- Patients with active uncontrolled CNS involvement with malignancy.

- Fertile men or women unwilling to use contraceptive techniques during and for 12
months following treatment.

- Females who are pregnant.

- Patients who are HIV positive

- Organ dysfunction

- Left ventricle ejection fraction < 35%.

- DLCO <35% of predicted, or receiving continuous supplementary oxygen.

- Liver function tests: total bilirubin >2x the upper limit of normal, and/or
transaminases >4x the upper limit of normal.

- Karnofsky score <50 for patients < 60 years, or <70 for patients aged 60 - 69
years

- Creatinine clearance < 60 ml/min.

- Patients with hypertension that is poorly controlled on antihypertensive
therapy.

- Patients with a positive PRA or anti-donor T or B cell (+) will be considered
for this treatment protocol only if no other option is available.
