Brief summary:
The purpose of this study is to develop a standard of care treatment using allogeneic stem cells for patients with cancers of the blood.

The protocol was revised to reflect that this study is considered "treatment guidelines", rather than a research study.

Detailed description:
Preparative regimen using total body irradiation (TBI) and cyclophosphamide:

1. on day -6 and -5: cyclophosphamide is given,
2. on day -4, -3, -2, and -1: TBI is given,
3. on day 0: stem cell or bone marrow is infused.

Alternate preparative therapy for patients not able to receive TBI

The chemotherapy (cyclophosphamide and busulfan) is given with the intent of destroying the bone marrow, eliminating any cancerous and preparing for the transplant of the donor's blood stem cells by suppressing the immune system.

l. Ten days before the transplant (Day 10), subjects will be admitted to the bone marrow transplant unit and placed in isolation to reduce exposure to infections. Isolation will be continued until adequate numbers of cells are present in the blood to fight infection.

2\. On day -9, -8, -7, -6 busulfan is given.

3\. On day -5, -4, -3, -2 cyclophosphamide is given.

4\. On day -1 no therapy is given (day of rest).

5\. On day 0 the donor stem cells are given intravenously. Additional cells may be given on day +1 or 2 as needed.

Transplant:

Subjects will be admitted to the bone marrow transplant unit and put in isolation to reduce exposure to infectious agents. During this time, they will receive the preparative treatment outlined above. Once they have received the preparative regimen, stem cells will be obtained from the donor and given intravenously.

The new stem cells will replace the bone marrow that was damaged by the treatment for the cancer.

Isolation will be continued until adequate numbers of cells are present in the blood to fight infection. Subjects will then be transferred from the bone marrow transplant unit and discharged from the hospital when medically ready. Subjects will be expected to return for follow-up to the bone marrow transplant clinic at specific dates as determined by their physician.

Arms: arm 1: Patients who are not able to receive Total Body Irradiation (TBI) receives cyclophosphamide, Busulfan and Peripheral Blood Stem Cells (PBSC) as a source of transplant arm 2: Patients who are not able to receive Total Body Irradiation (TBI) receives cyclophosphamide, Busulfan and Bone Marrow as a source of stem cell transplant arm 3: Patients who are not able to receive Total Body Irradiation (TBI) receives cyclophosphamide, Busulfan and Umbilical Cord Blood (UCB) as a source of stem cell transplant arm 4: Patients who receives Umbilical Cord Blood (UCB) as a source of transplant and who have not had chemotherapy in the prior 3 months receives ATG in addition to cyclophosphamide, Busulfan preparative regimen arm 5: Patients receiving cyclophosphamide, Total Body Irradiation (TBI) and Peripheral blood stem cells as a source of transplant arm 6: Patients receiving cyclophosphamide, Total Body Irradiation (TBI) and Bone Marrow as a source of stem cell transplant arm 7: Patients receiving cyclophosphamide, Total Body Irradiation (TBI), and Umbilical Cord Blood (UCB) as a source of stem cell transplant arm 8: Patients receiving cyclophosphamide, Total Body Irradiation (TBI) , CD4+CD25+ and Peripheral Blood Stem Cells (PBSC) as a source of transplant. These patients are co-enrolled on the MT2004-03 trial (NCT00725062)
Interventions: intervention 1: Stem Cell Transplant intervention 2: Cyclophosphamide intervention 3: Total Body Irradiation intervention 4: Busulfan intervention 5: Equine ATG (ATGAM) intervention 6: CD4+/CD25+ cells
Intervention descriptions: intervention 1: Certain cancers can be treated by giving patients stem cells that come from someone else. This is called a stem-cell transplant. As part of the transplant process, patients receive high doses of chemotherapy and/or radiation to treat their underlying disease, such as cancer. As one of its effects, this treatment also kills the healthy stem cells that are already in the marrow. The transplant provides new stem cells for the patient from a healthy donor; that replace the bone marrow and allow the blood counts to recover. (Allowable sources of stem cells = related or unrelated bone marrow or peripheral blood, for Busulfan/cyclophosphamide/ATG preparative chemo only, umbilical cord blood is also permitted.) intervention 2: 60 mg/kg intravenously (IV) Days -6 and -5 or 50 mg/kg/day IV Days -5 through -2. intervention 3: On Day -4, -3, -2, -1 total body irradiation is given twice daily. intervention 4: When not receiving total body irradiation, administered Days -9 through -6, 0.8 mg/kg/dose by intravenous dosing every 6 hours. intervention 5: UCB recipients who have not had chemotherapy in the preceding 3 months will also receive Equine ATG (ATGAM) 15 mg/kg IV will be administered every 12 hours for 6 doses beginning on day -3 per institutional guidelines intervention 6: On days -2, patients will receive CD4+/CD25+ cells intravenously.

OBJECTIVES
The purpose of this protocol is to study the use of related or unrelated allogeneic stem cell
transplantation as therapy for individuals with acute myelocytic leukemia (AML), acute
lymphocytic leukemia (ALL), chronic myelogenous leukemia (CML), chronic lymphocytic
leukemia, multiple myeloma, Hodgkin's disease, non-Hodgkin's lymphoma, myelodysplasia or
juvenile chronic myelogenous leukemia. Specifically, this study researches the following
question.
1.1With what frequency will allogeneic stem cell transplantation (BMT) along with
fractionated total body irradiation (TBI) and cyclophosphamide; or busulfan and
cyclophosphamide for patients who are ineligible for TBI, promote long-term disease-
free survival in patients with hematological malignancies?
2.0 BACKGROUND AND RATIONALE
Allogeneic bone marrow transplantation has been widely used for treatment of lethal
hematologic disorders. Extensive experience with bone marrow as the stem cell source
has documented the ability of engrafted marrow to restore hematopoiesis,
immunocompetence and protect against malignant recurrence leading to extended
disease-free survival for a sizable fraction of children and adults undergoing such
transplantation. Over the last 10 years, extensive clinical experience, confirmed in
several randomized trials, has suggested that for certain patient populations, G-CSF
mobilized peripheral blood from matched related or unrelated donors contains sufficient
stem cells for prompt engraftment and sustained hematopoiesis. While questions still
remain regarding the incidence, severity and duration of acute and chronic graft-versus-
host disease following allogeneic transplantation using blood-derived stem cells, it is well
established that these are a viable source of cells for use in allotransplantation. Peripheral
blood stem cell allografts have been associated with quicker neutrophil recovery and a
shorter time to platelet and red cell transfusion dependence then corresponding grafts
using marrow-derived stem cells. This has resulted in lesser early transplant-related
toxicity and mortality. Acute graft-versus-host disease has been either similar or slightly
less frequent than in marrow grafts, and chronic graft-versus-host disease has been
reported as either similar or slightly more frequent than grafts using marrow. Several
randomized trials have suggested a survival advantage for blood stem cell transplants,
particularly for high risk patients.
Experience at the University of Minnesota with over 100 such allografts confirms quicker
engraftment, but similar rates of graft-versus-host disease and disease-free survival,
compared to bone marrow transplants at our institution.
Recognizing this advantage for all, but the lowest risk group of patients, this study will
evaluate, in prospective fashion, the use of G-CSF mobilized donor blood stem cells in
patients undergoing allotransplantation. Those receiving unrelated donor grafts or those
whose donors are younger than age 12 will still undergo marrow harvests for stem cell

collection. All patients will receive uniform conditioning with cyclophosphamide and
fractionated total body irradiation for busulfan plus cyclophosphamide, if irradiation is
not possible. They will receive the multi-modal supportive care provided for all patients
undergoing transplantation at our institution. Standard post-transplant outcomes relating
to engraftment, graft-versus-host disease complications, malignant relapse and survival
will be evaluated.

Total Body Irradiation/cyclophosphamide Regimen
1320 cGy administered in 8 fractions of 165 cGy each with 2 fractions being
given each day. Total body irradiation is given at a dose rate of 10-19
cGy/minute prescribed to the midplane of the patient at the level of the umbilicus.
The total body irradiation will be delivered with right and left lateral fields, with
the patient supine on a specially designed couch. Based on measurements of
transverse thicknesses, aluminum compensators will be used to ensure that the
dose homogeneity across the field is within 10% of the prescribed dose. Usually
head/neck, leg and lung compensators are used (although based on calculated
mid-mediastinal doses, lung compensators are often not needed). Total body
irradiation will be delivered with a linear accelerator using 6, 18 or 24 MV xrays.
The energy used will be based on the calculated dose to the midline at points up
and down the patient's torso. The lowest energy that gives 90-100% of the
prescription point dose will be used. A beam "spoiler" will be used to ensure a
full skin dose. Half value layer lung and kidney blocks will not be utilized.
Testicular boosts should be used for all males with ALL (and according to
institutional practice for other diseases). The testicular boost is given in a single
400 cGy fraction with either electrons prescribed to Dmax or photons prescribed
to the midplane of the scrotum. If electrons are used, the energy for the testicular
boost depends on the thickness of the testicles and is chosen so that the D90
corresponds to the posterior surface of the scrotum.
Patients are eligible for any GVHD prophylaxis studies active at the University of
Minnesota.
Cyclophosphamide is to be given as a 2 hour infusion with strict attention given to
vigorous hydration, fluid balance, and maintenance of urine output.

of ATG per institutional guidelines. Additional steroids and/or other medications
may be used as needed per the discretion of the treating physician.

Cyclophosphamide will be given in a two-hour infusion with attention to vigorous
hydration, fluid balance and maintenance of urine output.
Mesna will be administered according to support protocol MT(S) 9006 during
cyclophosphamide infusion.
Patients will be started on G-CSF support on day +1 at 5 mcg/kg (IV/SQ)(round
to vial size) daily until ANC > 2500/μL for 2 consecutive days. Once a patient has 
met these criteria, the ANC will be monitored and G-CSF restarted if ANC falls
to < 1000.
Patients are eligible for any GVHD prophylaxis studies active at the University of
Minnesota or one of the regimens listed below:

Methotrexate and Cyclosporine A as per BMT standard of care protocol
MT1990-07S

Cyclosporine A and Mycophenolate mofetil as below
Cyclosporine A
Cyclosporine A (CSA) will start day -3 and will be administered PO/IV
maintaining a trough level between 200 and 400 ng/mL. For adults the
initial dose will be 2.5 mg/kg IV over 1 hour every 12 hours. For children
< 40 kg the initial dose will be 2.5 mg/kg IV over 1 hour every 8 hours.
CSA dosing will be monitored and altered as clinically appropriate per
institutional pharmacy guidelines. Dose adjustments will be made on the
basis of toxicity and/or low CSA levels.
Patients will receive CSA until approximately day +100. If no GVHD, the
dose will then be tapered 10% per week and discontinued approximately
at 6 months.
Mycophenolate mofetil (MMF)
Mycophenolate mofetil (MMF) 3 gram/day IV/PO for patients who are ≥ 
40 kg divided in 2 or 3 doses. Pediatric patient (<40 kilograms) will
receive MMF at the dose of 15 mg/kg/dose every 8 hours beginning day -
3. MMF dosing will be monitored and altered as clinically appropriate
based on institutional guidelines. Patients will be eligible for MMF dosing
and pharmacokinetics studies.
Stop MMF at day +30 or 7 days after engraftment, whichever day is later,
if no acute GVHD. (Definition of engraftment is 1st day of 3 consecutive
days of absolute neutrophil count [ANC) > 0.5 x 109 /L]).

TOXICITIES AND COMPLICATIONS
7.1
Donor


MT2001-02
May 30, 2012
Page 17 of 25
7.1.1
G-CSF. Administration of G-CSF in normal donors can be associated
with bone pain, headaches, body aches, fatigue, nausea, vomiting,
insomnia, dyspnea and other symptoms. Such symptoms are usually
minor, and may be controlled with administration of acetaminophen.
However, symptoms can occasionally be dose-limiting or require
cessation of G-CSF administration.
G-CSF administered in normal donors has rarely been associated with
hypokalemia and hypoglycemia. G-CSF administration may also be
associated with elevation of bilirubin, ALT and alkaline phosphatase.
These are transient abnormalities.
7.1.2
Apheresis
If antecubital veins are not suitable for apheresis, large-bore, Quinton
catheters in neck veins are required for the venous access necessary to
perform apheresis and peripheral blood progenitor cell collections. The 4-
6 hour collection procedures are occasionally associated with reversible
hypotension. Thrombocytopenia may develop transiently following the
apheresis especially if several aphereses are performed. G-CSF
administration may suppress the marrow response to thrombocytopenia.
Hypocalcemia secondary to the citrate anticoagulation may produce
tingling or paresthesis. Calcium supplements will be given as needed.
7.2
Recipient
7.2.1
Cyclophosphamide or Busulfan
Hemorrhagic cystitis may occur following the use of cyclophosphamide
despite aggressive fluid replacement, frequent voiding and Mesna.
Cyclophosphamide can cause fatal cardiac necrosis with clinical
irreversible heart failure. EKG changes are not infrequent and reduction
in EKG voltage may be observed. Patients previously treated with
anthracyclines or with mediastinal irradiation may be at higher risk.
Cyclophosphamide (with or without irradiation) may also induce
pericarditis.
Nausea, vomiting and diarrhea are frequent following high doses of
cyclophosphamide or busulfan. Aggressive anti-emetic therapy, including
Ondansetron, may be helpful in minimizing this problem.
Alopecia is common. It is usually reversible, but changes in hair color or
texture after regrowth may occur.


MT2001-02
May 30, 2012
Page 18 of 25
Skin rash may occur, but is infrequent. Busulfan may produce skin
hyperpigmentation.
Sterility: Permanent sterility is likely at this dose of cyclophosphamide,
particularly when given with other drugs and/or irradiation.
Busulfan may produce lung inflammation (pneumonitis), liver injury
leading to veno-occlusive disease and rarely seizures.
7.2.2
Total body irradiation
1320 cGy is administered in 8 fractions over 4 days. Nausea, vomiting
and diarrhea are common.
Generalized mild cutaneous erythema is frequently seen.
Parotitis may occur.
Lung: Inflammatory pneumonitis or even respiratory failure may develop
in the first three months following TBI. Late respiratory failure has been
seen in a small fraction of patients.
Liver: veno-occlusive disease may cause fluid retention, ascites, or renal
failure.
Sterility: Sterility is common after this dose of total body irradiation.
Brain damage can develop in a small fraction of treated patients.
7.2.3
Myelosuppression
Both the chemotherapy + TBI, or the chemotherapy only conditioning
induce significant myelosuppression requiring reinfusion of viable
hematopoietic stem cells for prompt marrow recovery. During the period
of myelosuppression and pancytopenia, the patient is highly vulnerable to
infection and/or bleeding. Irradiated red cell transfusions will be given to
maintain adequate oxygen delivery and platelet transfusions will be given
in an attempt to prevent bleeding. Various isolation and prophylactic
measures to reduce risks of infection and to vigorously treat any infections
will also be required.
7.2.4
Graft Failure


MT2001-02
May 30, 2012
Page 19 of 25
Infusion of allogeneic peripheral blood or bone marrow may be associated
with failure to engraft, partial engraftment of one, two, or three cell
lineages or late graft failure. Risk of graft failure will be minimized by
providing a targeted CD34+ cell dose of 5 x 106/kg recipient weight.
Graft failure may be treated with growth factors, infusion of additional
PBPC or of marrow or PBPC obtained from the original donor after
recognition of graft failure.
7.2.5
Graft vs. Host Disease (GVHD)
Infusion of allogeneic PBPC may be associated with development of acute
and/or chronic GVHD. An attempt to reduce incidence and severity of
GVHD will be made by limiting infusion of peripheral cells to a target
dose of 5 x 106 34+/kg recipient weight or 2.0 x 108 nc/kg of marrow cells
and by using GVHD prophylaxis consisting of methotrexate (MTX) and
cyclosporine (CSA) or alternative GVHD prophylaxis study approaches.
If Greater than 45kg: Cyclosporine 2.5mg/kg over 2 hours every
12 hours, begin on Day -3.
If Less than 45Kg: Cyclosporine 2.5mg/kg over 2 hours every 8
hours, begin on Day -3.
Cyclosporine Levels every Monday, Wednesday, and Friday beginning
Day -1 to Day +7, then Cyclosporine Levels every Monday.
7.2.6
Second Malignancy
The potential carcinogenic effects of the pre-transplant chemotherapy
and/or radiation may compound any inherent risks of second malignancy
already induced by treatment the patient may have already received. Both
late second epithelial malignancies and early treatment-associated
neoplasms (particularly post-transplant lympho-proliferative disorders)
may develop after transplantation.

STATISTICAL CONSIDERATIONS
8.1
Patient Accrual


MT2001-02
May 30, 2012
Page 20 of 25
Based on the BMT patient referral pattern of the University of Minnesota, we
expect to accrue up to 50 cases to this study each year. The overall case accrual
will be 350.
8.2
Statistical Analysis
The major end points of this study are engraftment failure, time to engraftment,
incidence and severity of acute and chronic GVHD, persistence or relapse of
malignancy and survival of the recipient. Data will be collected by nurse
coordinators and the personnel of the Biostatistical Support Group of the
University of Minnesota Blood and Marrow Transplant Program using
prospective data plans already in place for all patients enrolled in institutional
BMT protocols. These standard clinical end points will be evaluated using
conventional survival analysis methods, including the Kaplan-Meier or
cumulative incidence method and Cox proportional hazard models. Results will
be compared to historical data of allogeneic bone marrow transplantation.
Complication rates of recipients (and donors, if any) will be monitored and
descriptive statistics will be employed to assess their incidence. These will
include pneumonitis, veno-occlusive disease of the liver, hemorrhagic cystitis and
serious infection.
Note: Patients enrolled on additional investigational studies including, but not
limited to Treg infusions, may have their outcomes analyzed separately
8.3
Study Data & Safety Monitoring
This institutional continuing case series will be monitored by the PI and the Study
Committee assisted by the personnel and facilities of the Biostatistical Support
Group of the University of Minnesota Blood and Marrow Transplant Program.
Major and unexpected serious adverse events will be examined and reviewed
periodically. All on study deaths will be reviewed by the PI and as indicated by
the study committee and are reported to the IRB. Examination of accrual and
survival outcomes will be performed as indicated by study events or as required
by regulatory committees including the Cancer Center Protocol Review
Committee and the IRB.

APPENDIX TWO: TBI GUIDELINES
Fractionated Total Body Irradiation (In Lateral Position)
1320 cGy administered in an 8 fractions of 165 cGy each with 2 fractions being given each day.
Total body irradiation is given at a dose rate of 10-19 cGy/minute prescribed to the midplane of the
patient at the level of the umbilicus.
The total body irradiation will be delivered with right and left lateral fields, with the patient supine on
a specially designed couch.
Based on measurements of transverse thickness, aluminum compensators will be used to ensure that
the dose homogeneity across the field is within 10% of the prescribed dose. Usually head/neck, leg
and lung compensators are used (although based on calculated mid-mediastinal doses, lung
compensators are often not needed).
Total body irradiation will be delivered with a linear accelerator using 6, 18, 24 MV X-rays. The
energy used will be based on the calculated dose to the midline at points up and down the patient’s
torso. The lowest energy that gives 90-100% of the prescription point dose will be used.
A beam “spoiler” will be used to ensure a full skin dose.
Half value layer lung and kidney blocks will not be utilized.
Testicular boosts should be used for all males with ALL (and according to institutional practice for
other diseases). The testicular boost is given in a single 400 cGy fraction with either electrons
prescribed to Dmax or photons prescribed to the midplane of the scrotum. If electrons are used, the
energy for the testicular boost depends on the thickness of the testicles and is chosen so that the D90
corresponds to the posterior surface of the scrotum.
