Allogeneic Hematopoietic Cell Transplantation After Nonmyeloablative Conditioning for Patients With Severe Systemic Sclerosis

The purpose of the study is to examine the safety and effectiveness of a reduced intensity
conditioning regimen and allogeneic bone marrow transplant for people with systemic
sclerosis. In an allogeneic bone marrow transplant procedure, bone marrow is taken from a
healthy donor and transplanted into the patient. Bone marrow can be donated by a family
member or an unrelated donor who is a complete tissue type match.

Participants will receive the chemotherapy and low dose radiation conditioning regimen
consisting of the following: Fludarabine will be given intravenously for 5 days.
Cyclophosphamide will be given intravenously on the first and second day. After completing
the fludarabine and cyclophosphamide, patients will receive a single low dose of total body
irradiation. The next day, patients will receive the allogeneic bone marrow transplant. On
the third and fourth day after the transplant, patients will receive high dose intravenous
cyclophosphamide. This is given to help prevent two complications: (1) graft rejection, which
occurs when the body's immune system rejects the donor bone marrow, and (2) graft-versus-host
disease (GVHD), which is when the donor immune cells attack the patient's normal tissues. On
the fifth day after the transplant, patients will start receiving two additional medications:
tacrolimus and mycophenolic acid (MPA, Myfortic), to help prevent GVHD. Patients will receive
mycophenolic acid for about 5 weeks and tacrolimus for about 6 months. Also beginning on the
fifth day after the transplant, patients will receive daily injections of a growth factor
called granulocyte-colony stimulating factor (G-CSF), which is a protein that increases the
white blood cell count; G-CSF will be continued until the patient's white blood cell count
has returned to normal levels.

Patients will remain closely monitored either in the outpatient clinic setting or in the
hospital for approximately 2-3 months after the transplant, but possibly longer if there are
complications. Follow-up study visits will occur at 6 months and then at 1, 2, 3, 4, and 5
years after the transplant. Study researchers will keep track of the patient's medical
condition after leaving the transplant center by phone calls or mailings to patients and
their doctors once a year for the rest of the study participants' lives.

PRIMARY OBJECTIVES:

I. To determine the safety and potential efficacy of reduced intensity conditioning with
fludarabine/cyclophosphamide/low-dose total body irradiation (TBI) and allogeneic
hematopoietic cell transplantation (HCT) for the stabilization or regression of disease
manifestations of severe systemic sclerosis (SSc).

SECONDARY OBJECTIVES:

I. To determine whether stable allogeneic donor engraftment can be safely established with
reduced intensity conditioning followed by matched sibling or unrelated donor bone marrow
transplantation in patients with severe SSc.

OUTLINE:

Patients receive fludarabine phosphate intravenously (IV) on days -6, -5, -4, -3 and -2 and
Cyclophosphamide IV on days -6, -5, and undergo 2 Gray TBI on day -1. Patients receive human
leukocyte antigen (HLA)-matched donor bone marrow transplantation on day 0. Patients then
receive cyclophosphamide IV on days +3 and +4, and beginning day +5 they start tacrolimus
orally (PO) and enteric coated mycophenolic acid.

After completion of initial study treatment, patients are followed up at 6 months and then
annually for 5 years.

Inclusion Criteria:

- Patients eligible for the study must have a human leukocyte antigen (HLA)-identical
sibling or HLA-matched unrelated bone marrow donor available and willing to donate.

- Patients with severe SSc as defined by the American College of Rheumatology and at
high-risk for a fatal outcome based on the following prognostic factors in groups 1-5:

- Group 1: Patients must have 1) both a and b below; and 2) at least one of c, d or e:

- a. diffuse cutaneous scleroderma with skin score of greater than or equal to 16
(modified Rodnan scale [mRSS]).

- b. duration of systemic sclerosis less than or equal to 7 years from the onset of
first non-Raynaud's symptom.

- c. presence of interstitial lung disease (either forced vital capacity [FVC] or
corrected diffusing capacity of the lung for carbon monoxide [DLCOcorr] less than
70 % of predicted) and evidence of alveolitis (abnormal bronchoalveolar lavage
(BAL) or high resolution chest computed tomography [CT] scan) after treatment
with intravenous cyclophosphamide greater than or equal 2 grams given over at
least a 3 month period; for patients not able to adequately complete pulmonary
function tests (PFT), there must be evidence of progressive disease on chest CT.

- d. left heart failure with left ventricular ejection fraction (LVEF) < 50% (that
has responded to treatment targeted to scleroderma); 2nd or 3rd atrioventricular
(AV) block with other evidence of cardiomyopathy related to SSc; myocardial
disease not secondary to SSc must be excluded by a cardiologist.

- e. history of SSc-related renal disease that is not active at the time of
screening; history of scleroderma hypertensive renal crisis is included in this
criterion.

- Group 2: Progressive pulmonary disease as defined by a decrease in the FVC or DLCOcorr
by 15 percent or greater compared to a prior FVC or DLCOcorr in the previous twelve
month period; in addition, patients may have either less skin involvement than group 1
(mRSS less than 16) and the FVC or DLCOcorr is less than 70% or both FVC and DLCOcorr
greater than or equal to 70% if they have diffuse cutaneous disease (mRSS greater than
16) at screening for the study; patients must also have evidence of alveolitis as
defined by abnormal chest CT or BAL; for patients not able to adequately complete PFT,
there must be evidence of progressive disease on chest CT.

- Group 3: Have progressive active SSc after prior autologous transplant based on the
presence of progressive pulmonary disease; this will be defined by a decrease in the
FVC or DLCO adjusted since prior autologous transplant of 15 percent or greater of the
pre-transplant percent predicted value, in addition to evidence of alveolitis as
defined by chest CT changes or BAL. If patients had prior autologous HCT on the
"Scleroderma: Cyclophosphamide Or Transplantation" (SCOT) clinical trial, they must
have failed based on the defined study endpoints and be approved by the protocol
principal investigator (PI).

- Group 4: Patients who meet group 1 inclusion criteria but may have FVC or
DLCO-adjusted less than 70% plus have had an adverse event on cyclophosphamide
preventing its further use (specifically hemorrhagic cystitis, leukopenia with white
blood cell [WBC]< 2000 or absolute neutrophil count [ANC] < 1000 or platelet count <
100,000).

- Group 5: Diffuse scleroderma with disease duration less than or equal to 2 years since
development of first sign of skin thickening plus modified Rodnan skin score greater
than or equal to 25 plus erythrocyte sedimentation rate (ESR) > 25 mm/1st hour and/or
hemoglobin (Hb) < 11 g/dL, not explained by causes other than active scleroderma.

- Unless patients have a DLCO-adjusted less than 45%, patients in all groups must have
failed either oral or intravenous cyclophosphamide regimen defined as: IV
cyclophosphamide administration for at least > 3 months between first and last
cyclophosphamide dose at a total cumulative IV dose of at least 2 grams, oral
cyclophosphamide administration for > 4 months regardless of dose, or combination of
oral and IV cyclophosphamide for at least > 6 months independent of dose.

- DONOR: HLA genotypically identical sibling or unrelated donor; unrelated donors are
required to be matched by standard molecular methods at the intermediate resolution
level at HLA-A, B, C and DRB1 and the allele level at DQB1.

- DONOR: Donors must meet the selection criteria as defined by the Foundation for the
Accreditation of Cell Therapy (FACT) and will be screened per the American Association
of Blood Banks (AABB) guidelines

- DONOR: Bone marrow is the preferred cell source
