2.0 BACKGROUND
Approximately 30–40% of patients with acute myeloid leukemia (AML) experience induction
failures. In these patients who do not achieve remission with two cycles of standard induction therapies,
the probability of achieving remission with subsequent inductions is very limited. Hematopoietic stem
cell transplantation (HSCT) is the only curative option for these patients, but high relapse rate and
transplant-related mortality often preclude them to proceed to transplant. Thus, AML not in remission
at time of HSCT remains a huge unmet need in current HSCT practice, particularly if the patient does
not have a Human Leukocyte Antigen (HLA)-matched donor identified by the time of two induction
failures.
Salvage chemotherapy with Clofarabine appears to be another promising option in relapsed and
refractory AML. Clofarabine is a second-generation purine nucleoside analog with substantial
single-agent activity in adult patients with AML. In addition, Clofarabine is an effective
immunosuppressive agent and several trials have shown the feasibility of conditioning with
Clofarabine-based regimen1, 2. In the past, a conditioning regimen of Clofarabine and Busulfan × 4
(Clo/Bu4) has been successfully used prior to allogeneic stem cell transplantation for non-remission
AML with day +30 complete remission rates were 90–100%1, 2.  However, these patients were
transplanted with HLA matched donors.
It has been shown that Clo/Bu4 were utilized for refractory pediatric hematologic malignancies
prior to haploidentical stem cell transplantation, with reported leukemia-free survival of 167, 49, and
31 weeks, respectively, in three cases3. However, there are also data that Clofarabine may not be as
immunosuppressive as Fludarabine4, 5.
In treatment of very aggressive leukemia, a new approach to start transplant conditioning at nadir
during the previous chemotherapy defined as “preconditioning”, has been used in Europe since more
than 10 years ago6, 7. In these studies, there were only 3 days of rest between induction chemotherapy
and the beginning of transplant conditioning regimen. More recently, another European group5 used
Clofarabine (30 mg/m2/day IV × 5 days) as a preconditioning, and (Flu/Cy/Mel+ total body irradiation
(TBI)) for haploidentical transplant in high-risk AML patients. In this regimen, again, there were 3
days in between preconditioning (cytoreduction) and conditioning.  The median duration of severe
neutropenia following the initiation of Clofarabine was 31 days (range, 24–68 days). No patient died

during the very early phase of transplantation including cytoreduction, conditioning, and
transplantation procedure. There was no case of Sinusoidal Obstructive Syndrome (SOS). Most
commonly seen grade IIII–V toxicities were transient, as elevation of transaminases (44.4%), mucositis
(38.9%), skin reactions including hand-foot syndrome (16.7%), creatinine elevation (16.7%), and
nausea/vomiting (16.7%)8.
Locke et al9, 10 has reported prospective phase II study results of 29 patients given Clofarabine
30 mg/m2/day IV × 5 days followed immediately by HCT conditioning while at the cytopenic nadir.
Toxicities were acceptable, with transient hyperbilirubinemia (48%) and grade 3–4 infections (10%).
Post HCT, 180 day non-relapse mortality (NRM) was 7% (95% confidence interval (CI): 1–21), relapse
was 29% (95% CI: 13–46) and OS was 71% (95% CI: 51–85), comparing favorably to published data
for high-risk patients. There were no cases of veno-occlusive disease. Therefore, Clofarabine used as
a bridge to HCT reduces disease burden, is well tolerated, and permits high-risk patients to undergo
HCT with acceptable NRM.
Moreover, Dr. Deborah Richardson and colleagues conducted 11 cases of Clofarabine
preconditioning in patients with high-risk, refractory acute leukemia or advanced Myelodysplastic
Syndrome (MDS).  Six patients received even CyTBI conditioning, and five patients received various
reduced intensity conditioning. The patients tolerated conditioning well and overall TRM (transplant
related mortality) was 8% by one year. One-year overall survival was about 48% in this highly
aggressive AML population.11  
In addition, our group at Penn State Cancer Institute has recently used Clofarabine as
preconditioning (cytoreduction), after 3 days followed by Flu/Bu3/total body irradiation (TBI)
conditioning for haploidentical stem cell transplant with Post-Transplant Cyclophosphamide (PTCy)
in two refractory AML patients. These patients had 45% and 60% bone marrow blasts at the time of
transplant, respectively, which usually precludes patients as transplant candidates. Both patients
achieved complete remission (CR) after transplant and now both are alive in CR for almost 2 years.  
Clofarabine was administered 30 mg/m2/day IV × 5 days. Busulfan was 3-day infusion. Our proposed
protocol will utilize a similar regimen except a reduced Busulfan dose.
These regimens are summarized in Appendix B.  It has been shown that myeloablative transplant
conditioning regimens can be tolerated during nadir after Clofarabine 30-40 mg/m2 x 5 day treatment.
Our proposed regimen in the current study is moderate in terms of intensity compared to published
studies.
The lack of available donors, treatment toxicities, and poor responses to salvage chemotherapy
results in very few non-remission AML patients proceeding to hematopoietic stem cell transplantation.
As stated above, third or subsequent inductions are very unlikely to be successful. Thus, after two
induction failures, moving towards transplantation may be desirable. To test this hypothesis, we would
like to adopt scheme of stem cell transplantation after two induction failures for patients with
haploidentical donors (related) as well as matched and mismatched unrelated donors using clofarabine
preconditioning and post-transplant cyclophpsophamide (Fig. 1) to achieve a long-term remission as
the goal of AML treatment. Even in the previous Clo/Bu4 studies, we observed a relapse rate of about
45% after achieving the first complete remission1. We would like to propose a protocol for non-
remission AML and expand the patient population to older than 55 years of age as well as those who
relapsed after initial allogeneic transplant to improve enrolling patients in the near future.12-14 We have
many patients achieving remission but for those without remission, clofarabine preconditioning may
be a reliable protocol to bring these patients into the early complete remission.

Clofarabine Administration
Prior to administration of clofarabine, the following must occur:
• Drugs with known renal toxicity should be avoided during the 5 days of clofarabine treatment.
• Concomitant use of medications known to induce hepatic toxicity should be avoided.  
• Hepatic and renal function should be assessed prior to and during treatment.
• Patients should receive hydration each day of clofarabine treatment.
• To the extent possible, use of nephrotoxic (e.g., vancomycin, amphotericin B, etc.) and hepatotoxic
(e.g., voriconazole, cyclosporine, etc.) agents is to be avoided during clofarabine administration.
Pre Medication
Prophylactic steroid administration for this study is Dexamethasone 10 mg IV daily during the 5 days
of Clofarabine. The Dexamethasone should be given at least 30 minutes prior to clofarabine initiation.
Assessments for Capillary Leak Syndrome:
The following should be assessed daily during clofarabine administration:
•
≥grade 2 tachypnea or other evidence of respiratory distress;
•
unexplained hypotension;
•
unexplained tachycardia
If one or more of the above occur during study drug infusion, clofarabine administration is to be
interrupted until the resolution of the symptoms. Thus, if the patient’s condition stabilizes or improves,
clofarabine administration may resume.  Standard infusion time for this dose of clofarabine is planned
for 1 hour, however a slower infusion rate over at least 2 hours may be considered with the development
of Capillary Leak Syndrome.  If prophylactic dexamethasone is given and grade 2 or greater signs or
symptoms of Capillary Leak Syndrome develop, it is suggested to increase the dexamethasone dose to
20 mg prior to each subsequent dose upon recovery to grade 1 or lower toxicity.  If Capillary Leak
Syndrome (grade 2 or greater) recurs despite reducing infusion rate by over 2 hours and increasing
Dexamethasone, a 25% dose reduction of the clofarabine should be employed after recovery to grade
1 or lower toxicity.  
Anti-Emetics
Clofarabine is moderately emetogenic; therefore, standard anti-emetic therapy such as ondansetron and
dexamethasone should be administered prior to use of clofarabine.

Clofarabine Dose Modifications
The trial will start the clofarabine dose of 30 mg/m2 and use the following stopping rule: if any grade
4 or 5 non-hematological toxicities which are unexpected and related occur in 2 of the first 3 subjects,
or 3 of 6, 4 of 9, 5 of 12, 6 of 16 or 7 of 19, then clofarabine will be reduced to 20 mg/m2 with the next
subject enrolled.
Once the dose modification has occurred, re-escalation of clofarabine to 30mg/m2 is not permitted.
If the dose de-escalates to 20 mg/m2, the following same stopping rule will be used to ensure subject
safety. If any grade 4 or 5 non-hematological toxicities which are unexpected and related occur in the
2 of  the first 3, or 3 of 6, 4 of 9, 5 of 12, 6 of 16 or 7 of 19, subjects at the 20 mg/m2 dose level, the
trial will be stopped.  
6.2. Anti-Seizure Prophylaxis: Anti-seizure prophylaxis will be administered as per standard
practice.
      6.3. Infection Prophylaxis and Testing: Antibacterial, antiviral, and antifungal prophylaxis
and related blood testing during neutropenia until engraftment will be according to standard
practice.
6.4. GVHD Prophylaxis: GVHD prophylaxis consists of post-HSCT Cyclophosphamide,

8.0. ALLOGENEIC STEM CELL INFUSION:  The day of the stem cell/marrow infusion will
be defined as day 0. If more than one day of infusion is required, then these days are defined
as day 0a and day 0b accordingly.  The first day after the last stem cell infusion will be
defined as day +1.
Patients will not receive any immunosuppression (unless definitely indicated per the treating
physician) between day 0 and day 5 due to concern for mitigating the immuno-suppressive
effect of post-transplant Cyclophosphamide (given on days +3 and +4).
8.1. Stem Cell Source: The source of Haploidentical donor stem cells will be peripheral
blood stem cells (PBSC) or bone marrow (BM). PBSC will be preferred.  Cord
blood will not be allowed.  
8.2. PBSC Mobilization and Collection:  PBSC mobilization and collection procedures
and BM collection procedures will follow standard practice.
8.3. Stem Cell Dosing for PBSC Infusions: The recommended stem cell dose is 4-5 x106
CD34 cells/kg recipient weight. The minimum accepted stem cell dose is 2 x106 CD34
cells/kg recipient weight.

is 24 months at room temperature.  Ongoing stability studies will continue to confirm the
appropriate quality of drug product used for clinical trials beyond 24 months.
Clofarabine for injection should be diluted with 0.9% sodium chloride injection USP or
European Pharmacopeia (EP) normal saline (NS) or 5% dextrose injection (D5W) USP or EP
prior to IV infusion.  The resulting admixture may be stored at room temperature, but must be
used within 24 hours of preparation.
9.1.5. Toxicity: Adult Patients: Drug-related adverse effects observed in at least 10% of
adult patients treated with Clofarabine in previous clinical trials include myelosuppression,
nausea, vomiting, infections, fatigue, headache, diarrhea, rigors, dermatitis, anorexia, febrile
neutropenia, myalgia, asthenia, petechiae, transient elevated liver enzymes, stomatitis, mucositis,
pyrexia, flushing, constipation, edema, dehydration, nervousness, stomach pain, insomnia,
depression, dry skin, back pain, and decreased weight.8  
Adverse effects reported in <10% of adult patients include tumor lysis syndrome, capillary
leak syndrome, palmar plantar erythrodysesthesia, pancreatitis, seizures, irregular heartbeat,
edema, pericardial effusion, multi-organ failure, Stevens Johnson syndrome, and death. B
9.1.6. Guidelines for Clofarabine Administration: Clofarabine should be diluted with
NS or D5W prior to administering by IV infusion.  The dosage is based on the patient’s body
surface area (BSA), calculated using the actual height and weight before the start of each cycle.  
The timing for the infusion will be as per standard practices for this medication.  To prevent drug
incompatibilities, no other medications should be administered through the same IV line.   Drug
dosages can be rounded to the nearest integer per standard practice.  
Clofarabine Administration
Prior to administration of clofarabine, the following must occur:
• Drugs with known renal toxicity should be avoided during the 5 days of clofarabine treatment.
• Concomitant use of medications known to induce hepatic toxicity should be avoided.  
• Hepatic and renal function should be assessed prior to and during treatment.
• Patients should receive hydration each day of clofarabine treatment.
• To the extent possible, use of nephrotoxic (e.g., vancomycin, amphotericin B, etc.) and hepatotoxic
(e.g., voriconazole, cyclosporine, etc.) agents is to be avoided during clofarabine administration.
Pre Medication
Prophylactic steroid administration for this study is Dexamethasone 10 mg IV during the 5 days of
Clofarabine. The Dexamethasone should be given at least 30 minutes prior to clofarabine initiation.
Assessments for Capillary Leak Syndrome:
The following should be assessed daily during clofarabine administration:
•
≥grade 2 tachypnea or other evidence of respiratory distress;
•
unexplained hypotension;
•
unexplained tachycardia
If one or more of the above occur during study drug infusion, clofarabine administration is to be
interrupted until the resolution of the symptoms. Thus, if the patient’s condition stabilizes or improves,
clofarabine administration may resume.  Standard infusion time for this dose of clofarabine is planned
for 1 hour, however a slower infusion rate over at least 2 hours may be considered with the development
of Capillary Leak Syndrome.  If prophylactic dexamethasone is given and grade 2 or greater signs or
symptoms of Capillary Leak Syndrome develop, it is suggested to increase the dexamethasone dose to
20 mg prior to each subsequent dose upon recovery to grade 1 or lower toxicity.  If Capillary Leak
STUDY00010785
Approval: 11/22/2022

Protocol 18-011
14
Syndrome (grade 2 or greater) recurs despite reducing infusion rate by over 2 hours and increasing
Dexamethasone, a 25% dose reduction of the clofarabine should be employed after recovery to grade
1 or lower toxicity.  
Anti-Emetics
Clofarabine is moderately emetogenic; therefore, standard anti-emetic therapy such as ondansetron and
dexamethasone should be administered prior to use of clofarabine.
Clofarabine Dose Modifications
The trial will start the clofarabine dose of 30 mg/m2 and use the following stopping rule: if any grade
4 or 5 non-hematological toxicities which are unexpected and related occur in 2 of the first 3 subjects,
or 3 of 6, 4 of 9, 5 of 12, 6 of 16 or 7 of 19, then clofarabine will be reduced to 20 mg/m2 with the next
subject enrolled.
Once the dose modification has occurred, re-escalation of clofarabine to 30mg/m2 is not permitted.
If the dose de-escalates to 20 mg/m2, the following same stopping rule will be used to ensure subject
safety. If any grade 4 or 5 non-hematological toxicities which are unexpected and related occur in the
2 of  the first 3, or 3 of 6, 4 of 9, 5 of 12, 6 of 16 or 7 of 19, subjects at the 20 mg/m2 dose level, the
trial will be stopped.

Protocol 18-011
15
the white solid cake. Reconstituted in 2mL of sterile water, the solid cake produces a solution with
approximate concentration of 25mg/mL Fludarabine phosphate. Standard practice for preparation
and administration procedures of Fludarabine will be followed. Reconstituted drug contains no
antimicrobial preservative hence should be utilized within 8 hours of reconstitution. DO NOT
infuse concomitantly with another intravenous solution of unknown compatibility.
9.3 Cyclophosphamide (Cytoxan®)
General:  
Cyclophosphamide
monohydrate
(cyclophosphamide)
is
a
synthetic
antineoplastic drug chemically recognized as 2-[bis(2-cholorethyl)amino]tetrahydro-2H-1,3,2-
oxazaphosphorine 2-oxide monohydrate. The molecular formula of cyclophosphamide is
C7H15Cl2N2O2P·H2O with a molecular weight of 279.1 g/mol.  Unopened vials should be stored
at or below 25°C (77°F).
Mechanisms
of
Action:  
A
multistep
process
activates
it
by
conversion
to
4
hydroxycyclophosphamide by the liver microsomal oxidase system and to aldophosphamide by
tautomerization in the peripheral tissues. Aldophosphamide spontaneously degrades into acrolein
and phosphoramide mustard, which cause cellular glutathione depletion and DNA alkylation. This
results in inhibition of DNA replication and transcription. Cells expressing high levels of aldehyde
dehydrogenase (e.g. stem cells, L1210 leukemia cells) resist cyclophosphamide-mediated
cytotoxicity as aldophosphamide is inactivated by this enzyme. The drug also does not affect
quiescent cells and therefore stem cells are generally protected, an important factor if autologous
hematopoietic recovery is relied on in the event of graft failure.
Metabolism: Cyclophosphamide is broken down as described above and the breakdown
products are excreted by the kidneys. It is a substrate of CYP2A6 (minor), CYP2B6 (major),
CYP2C19 (minor), CYP2C9 (minor), CYP3A4 (minor); Note: Assignment of Major/Minor
substrate status based on clinically relevant drug interaction potential; Inhibits CYP3A4 (weak);
Induces CYP2B6 (weak/moderate), CYP2C9 (weak/moderate).
Incompatibilities:
Phenobarbital
or
rifampin
may
increase
the
toxicity
of
cyclophosphamide. Concurrent allopurinol or thiazide diuretics may exaggerate bone marrow
depression, may prolong neuromuscular blockade from succinylcholine cardiotoxicity, may be
additive with other cardio toxic agents (cytarabine, daunorubicin, doxorubicin) and may decrease
serum digoxin levels. Additive bone marrow depression with other antineoplastics, or radiation
therapy, may potentiate the effects of warfarin. Other incompatibilities include possible decreased
antibody response to live-virus vaccines and increased risk of adverse reactions, as well as,
prolongation of the effects of cocaine.
Toxicity:
Common side effects of cyclophosphamide include: nausea, vomiting, alopecia,
leucopenia, interstitial pneumonitis, interstitial pulmonary fibrosis, anaphylactic reactions,
amenorrhea, hemorrhagic cystitis, oligospermia or azoospermia and suppression of immune
responses. Less common side effects include: secondary malignancies in patients diagnosed with
a primary malignancy, fetal harm when administered to pregnant women, acute cardiac toxicity,
congestive heart failure, hemorrhagic myocarditis, hemopericardium, and possible cross
sensitivity with other alkylating agents. Additional less common side effects include: water
retention due to inappropriate secretion of anti-diuretic hormone (SIADH), cardiomyopathy with
myocardial necrosis, congestive heart failure, hemorrhagic cystitis, alopecia, skin rash, pulmonary
fibrosis, and sterility.
Available Forms: IV Cyclophosphamide is available as a sterile white crystalline powder.
STUDY00010785
Approval: 11/22/2022

Protocol 18-011
16
Cyclophosphamide is stored in a single dose vial with 500mg of the powder.
Reconstitution and Administration: Cyclophosphamide for parenteral use must be prepared
by either adding 0.9% sodium chloride solution, if injected directly, or sterile water, if infused.
Constituted in water, Cyclophosphamide is hypotonic, hence should not be injected directly.
Solutions of Cyclophosphamide with sodium chloride solution may be injected, intravenously,
intramuscularly, intraperitoneally, or intrapleurally. Constituted Cyclophosphamide is physically
and chemically stable for 24 hours at room temperature or six days refrigerated. Prepared solutions
do not contain any microbial preservative; hence sterility of the solutions should be monitored.  
9.4 Busulfan (Busulfex®):
General: Busulfan is a bifunctional alkylating agent known chemically as 1,4-butanediol,
dimethanesulfonate with a molecular formula of CH3SO2O(CH2)4OSO2CH3 and a molecular
weight of 246 g/mol.
Toxicity:
Toxicities reported as more than 10% incidence include: Tachycardia, hypertension,
edema, thrombosis, chest pain, vasodilation, hypotension,  insomnia, fever, anxiety, headache,
chills, pain, dizziness, depression, confusion, rash, pruritus, alopecia, hypomagnesemia,
hyperglycemia, hypokalemia, hypocalcemia, hypophosphatemia, nausea, mucositis/stomatitis,

allergic reaction.  
Toxicities with expected incidences are 1% to 10% include: Arrhythmia, cardiomegaly,
atrial fibrillation, ECG abnormality, heart block, heart failure, pericardial effusion, tamponade,
ventricular
extrasystoles,
hypervolemia,
lethargy,
hallucinations,
agitation,
delirium,  
encephalopathy, seizure, somnolence, cerebral hemorrhage, vesicular rash, vesiculobullous rash,
skin discoloration, maculopapular rash, acne, exfoliative dermatitis, erythema nodosum,

hepatomegaly, hematuria, dysuria, hemorrhagic cystitis, BUN increase, asthma, alveolar
hemorrhage, hyperventilation, hemoptysis, pleural effusion, sinusitis, atelectasis, hypoxia.
Available Forms: IV Busulfan (Busulfex) is supplied as a clear, colorless, sterile solution
in 10-mL single-use glass vials each containing 60 mg of Busulfan at a concentration of 6 mg/mL
for intravenous use.  IV Busulfan is packaged in a tray pack of 8 vials. Unopened vials of Busulfex
must be stored under refrigerated conditions between 2°-8°C (36°-46°F).
Reconstitution and Administration: IV Busulfan must be diluted prior to use with either
NS or D5W. The diluent quantity should be 10 times the volume of Busulfex, so that the final
concentration of busulfan is approximately 0.5 mg/mL. Infusion pumps should be used to
administer the diluted Busulfan solution. DO NOT infuse concomitantly with another intravenous
solution of unknown compatibility. Warning: Rapid infusion of IV Busulfan has not been tested
and is not recommended.
9.5 Tacrolimus (Prograf®):
General:  Tacrolimus is a macrolide immunosuppressant produced by Streptomyces
Tsukubaensis. Tacrolimus has an empirical formulation of C44H69NO12-H2O and a formula
Approval: 11/22/2022

Protocol 18-011
17
weight of 822.05 g/mol. Tacrolimus appears as white crystals or crystalline powder. It is
practically insoluble in water, freely soluble in ethanol, and very soluble in methanol and
chloroform.
Mechanisms of Action:  Tacrolimus inhibits T-lymphocyte activation, although the exact
mechanism of action is not known. Experimental evidence suggests that tacrolimus binds to an
intracellular protein, FKBP-12. A complex of tacrolimus-FKBP-12, calcium, calmodulin, and
calcineurin is then formed and the phosphatase activity of calcineurin is inhibited.  This effect
may prevent the dephosphorylation and translocation of nuclear factor of activated T-cells (NF-
AT), a nuclear component thought to initiate gene transcription for the formation of lymphokines
(such as interleukin-2, gamma interferon). The net result is the inhibition of T-lymphocyte
activation (i.e., immunosuppression).
Toxicity:
Possible side effects of Tacrolimus include: Depressed kidney function, high blood sugar,
high blood potassium, skin rash, headache, nausea, vomiting.
Less common side effects include: Loss of appetite, sleep disturbances, vivid dreams,
hallucinations, high blood pressure, seizure, decreased level of consciousness, anemia, agitation,
tremors, irritability, slurred speech, tingling in the hands and feet, pain in the palms and soles of
the feet, weakness, and abnormal blood cell levels. All of these side effects are reversible by
reducing the dose or discontinuing the drug. Rare fatal cases of severe allergic reactions have been
reported in patients receiving Cyclosporine and it is possible that similar reactions could also
occur in patients receiving tacrolimus.
Available Forms: Tacrolimus is available for oral administration as capsules (Tacrolimus
capsules) containing the equivalent of 0.5 mg, 1 mg and 5 mg of anhydrous Tacrolimus. Inactive
ingredients include lactose, hydroxypropyl methylcellulose, croscarmellose sodium, and
magnesium stearate. The 0.5 mg and 1 mg capsule shell contains gelatin and titanium dioxide,
and the 5 mg capsule contains gelatine, titanium dioxide, and ferric oxide. Tacrolimus is also
available as a sterile solution (tacrolimus injection) containing the equivalent of 5 mg anhydrous
Tacrolimus in 1 mL for administration by IV infusion only. Each mL contains polyoxyl 60
hydrogenated castor oil (HCO-60), 200 mg, and dehydrated alcohol, USP, 80.0% v/v.
Tacrolimus capsules should be stored at room temperature between 15° and 30°C (59° and
86°F). Tacrolimus injection should be stored between 5° and 25°C (41° and 77°F).
Reconstitution and Administration: Tacrolimus (Prograf injection) must be diluted with
NS or D5W before use. Tacrolimus is administered as a continuous infusion. Oral preparation
will be administered on empty stomach every 12 hours.
9.6
Mycophenolate Mofetil (MMF, CellCept):
General: CellCept (Mycophenolate Mofetil) is the 2-morpholinoethyl ester of
mycophenolic acid (MPA); an immunosuppressive agent; inosine monophosphate dehydrogenase
(IMPDH) inhibitor. The chemical name for mycophenolate mofetil (MMF) is 2-morpholinoethyl
(E)-6-(l,3-dihydro-4-hydroxy-6-methoxy-7-methyl-3-oxo-5-isobenzofuranyl)-4-methyl-4-
hexenoate. It has an empirical formula of C23H31NO7 a molecular weight of 433.50 g/mol.
Mycophenolate Mofetil is a white to off-white crystalline powder. It is slightly soluble in water
(43 μg/mL at pH 7.4); the solubility increases in acidic medium (4.27 mg/mL at pH 3.6). It is
freely soluble in acetone, soluble in methanol, and sparingly soluble in ethanol. The apparent
partition coefficient in 1-octanol/water (pH 7.4) buffer solution is 238. The pKa values for
mycophenolate mofetil are 5.6 for the morpholino group and 8.5 for the phenolic group.
STUDY00010785
Approval: 11/22/2022

Protocol 18-011
18
Mycophenolate mofetil hydrochloride has a solubility of 65.8 mg/mL in D5W. The pH of the
reconstituted solution is 2.4 to 4.1.
Mechanisms of Action:  Inhibits the enzyme inosine monophosphate dehydrogenase,
which is involved in purine synthesis. This inhibition results in suppression of T- and B-
lymphocyte proliferation.
Metabolism: Following oral and IV administration, mycophenolate is rapidly hydrolyzed
to mycophenolic acid (MPA), its active metabolite. Distribution is unknown. MPA is extensively
metabolized; <1% excreted unchanged in urine. Some enterohepatic recirculation of MPA occurs.
Half Life: MPA¾17.9 hr.
Incompatibilities: Combined use with Azathioprine is not recommended as, the effects are
unknown. Acyclovir and Ganciclovir compete with MPA for renal excretion and, in patients with
renal failure, may increase each other's toxicity.  Magnesium and aluminum hydroxide antacids
decrease the absorption of MPA; therefore, subjects should avoid simultaneous administration.
Cholestyramine and colestipol decrease the absorption of MPA; therefore, subjects should avoid
concurrent use. Toxicity may be increased by salicylates. Use of MMF may interfere with the
action of oral contraceptives. As a result of this interference, additional contraceptive method
should be used. Use of MMF may also decrease the antibody response to and increase risk of
adverse reactions from live-virus vaccines, although influenza vaccine may be useful. When
administered with food, peak blood levels of MPA are significantly decreased.
Toxicity:
Toxicities reported as more than 20% incidence include: Hypertension, hypotension,
peripheral edema, chest pain, tachycardia, pain, headache,  insomnia, fever, dizziness, anxiety,
rash, hyperglycemia, hypercholesterolemia, hypomagnesemia, hypokalemia, hypocalcemia,

Available Forms: Neupogen is marketed as a sterile, clear, colorless preservative-free
liquid. It is packaged in vials and prefilled syringes. The vials are single-dose, preservative-free
and contain 300 mcg/mL of Filgrastim. The prefilled syringes are single-dose, preservative free
and hold 600 mcg/mL of Filgrastim. Neupogen must be stored refrigerated at 2° to 8°C (36° TO

46°F). Avoid shaking. Preceding injection, Neupogen must reach room temperature for at most
24 hours. Discard any vials or prefilled syringes left at room temperature for more than 24 hours.
Avoid use if particulate matter or discoloration is observed prior to administration
Reconstitution and Administration:  Neupogen may be administered as an IV or a
subcutaneous infusion. It is recommended that Neupogen be administered at least 24 hours after
bone marrow infusion, with dosage modifications determined by neutrophil response. If
necessary, Neupogen maybe diluted in 5% dextrose with addition of albumin (human) to prevent
absorption to plastic materials. Dilution to final concentration less than 5 mcg/mL is not
recommended at any time. Do not dilute with saline as product may precipitate. When using either
vials or prefilled syringes, do not save unused drugs for later administration. Dispose of all unused
portions.
Filgrastim (G-CSF) will be administered per therapeutic standard of care beginning Day
+5 at approximately 5 mcg/kg with rounding to the nearest vial size permitted. Treatment will
continue until engraftment.  Additional doses may be given at the discretion of the treating
physician.  
9.8
Total Body Irradiation (TBI):
General: TBI shall be administered in accordance with the American College of Radiology-
American Society for Radiation Oncology (ACR-ASTRO) Practice Guideline for the Performance
of Total Body Irradiation. The subject will be evaluated by a qualified radiation oncologist prior
to initiation of TBI, and the plan of care communicated with the referring physician and other
physicians involved in the subject’s care. The recipient’s diagnosis, relevant medical history
including pre-existing comorbid conditions, and proposed preparative regimen will be made
available to the radiation oncologist in writing. The radiation oncologist’s clinical evaluation will
be documented in the electronic medical record and will address any prior radiation treatment the
recipient may have received, any other factors that may increase the toxicity of radiation, and will
describe a plan for delivery of radiation treatment.
After obtaining informed consent for TBI, a planning simulation in the anticipated treatment
position will be performed for the subject. The treatment position will be determined by the
radiation oncologist in collaboration with the medical physicist and radiation therapist. Physical
measurements of the subject at multiple locations for both anterior-posterior and lateral separations
will be taken by the medical physicist and radiation therapist. The radiation prescription will be
200 cGy in 1 fraction prescribed to the midline at the level of the umbilicus. For low-dose TBI
used on this protocol, organ shielding such as lung blocks will not be routinely utilized. Individual
subject specific considerations such as prior radiotherapy or clinically significant pulmonary
comorbidities may warrant organ shielding at the discretion of the radiation oncologist.
Calculations will be performed by a qualified medical dosimetrist or medical physicist to
determine the beam-on time necessary to achieve the prescribed dose. Consideration will be given
to differences in the subject’s separation in different body regions with the resulting dose
heterogeneities. The dose rate will be kept to <0.2 Gy per minute to reduce risk of interstitial
pneumonitis.
TBI will be delivered on Day –1 per protocol. Verification simulation will be performed in
the treatment position prior to treatment. A treatment margin of at least 5 cm around the subject
will be verified. A beam spoiler will be used to prevent skin sparing. The subject setup will be
reviewed by the radiation oncologist including any organ block placement verification imaging if
applicable.  The subject will be treated according to the approved simulation and treatment plan

21
instructions by at least two licensed radiation therapists under the direct supervision of the
radiation oncologist. The radiation treatment team will follow neutropenic precautions including
proper hand hygiene and the use of facial masks throughout the pre-treatment setup and TBI
treatment delivery.
All treatment planning and delivery documents will be maintained the radiation oncology
electronic medical record.
Toxicity: TBI will be administered per standard practice as implemented by radiation
oncologists. TBI alone for post-pubescent subjects with dose/fractionation not exceeding 2 Gy x
6 is well within the tolerance of most normal organs for <5% risk of severe late toxicity (organ
failure or major dysfunction) by 5 years. Notable exceptions are risk of cataract development, bone
marrow suppression, ovarian and testicular dysfunction. Also, there is a small risk of second
malignancy.  The most common acute effects include nausea, vomiting, diarrhea, and painful
swelling of the parotid glands.
When TBI is given in conjunction with other therapies in the transplant setting, there is
additional risk of side effects including loss of appetite, dry mouth, difficult or painful swallowing,
headache, stomatitis (sore throat/mouth), altered skin integrity, hair loss, swelling, increased risk
for infection and/or bleeding, possible lung failure, dry cough, fatigue, anxiety, fever, possible
liver failure, lung scarring, loss of vision, shortness of breath,  sterility, heartburn, cystitis, sleep
disturbances altered gastrointestinal, genitourinary, and endocrine function, neuropathy, fistulas,
pericarditis and increased risk of a second cancer.
Overall, the incidence of most major toxicities when radiation is given in conjunction with
other therapy as outlined above is still low, but rare, serious side effects are possible.
10.0 LABORATORY EVALUATIONS, CORRELATIVE AND SPECIAL STUDIES
10.1.   Laboratory Correlative Studies
10.1.1. Chimerism Study After Stem Cell Transplant  
After HSCT, donor cells and recipient cells co-exist for a while in a condition
called mixed chimera.  As time goes by, the donor cells become dominant if
engraftment is successful.  Once recipient cells are no longer detected (>95%
donor), it is called complete donor-type chimera.  At PSCI’s Bone Marrow
Transplant (BMT) program, whole blood and T-cell chimerism are tested as a part
of standard practice.  T-cell chimerism may be more predictive of the fate of graft
(complete chimerism, rejection, and possibly relapse of underlying diseases).  
Results of routine chimerism studies will be entered into the study database.   
Laboratory testing for chimerism evaluation will be obtained by the inpatient or
outpatient clinical team and submitted to the Penn State HLA Laboratory for standard
processing. Guidelines for chimerism processing is noted below.  
•
DNA extraction is performed by automated DNA extractor, EZ1 Advanced
XL (Qiagen), using EZ1 DNA Blood kit for whole blood DNA and EZ1 DNA
tissue kit for T-cell DNA.
•
Donor/recipient pre-and post-HSCT chimerism are evaluated for 22 short-
tandem repeat (STR) markers of by PowerPlex Fusion System (200)

Subjects who relapse or start maintenance any time after Day +30 will be taken off
study. Progression and survival should only be performed once the subject off study, either
from progression or the subjects have completed the trial.  For those that have progressed,
it should be every six months for the first year then annually for five years.  For those that
have completed the trial, it should be every six months from end of study for the first year
then annually for five years.
11.9 Assessment of GVHD
Acute GVHD typically occurs after engraftment of the stem cells. Clinical assessment for
acute GVHD will start after infusion of the stem cells on Day 0. There are 2 grading systems used
for acute GVHD: the modified Keystone (Glucksberg) and consensus criteria (grades I-IV). Both
systems were shown to equally predict survival15. The National Cancer Institute (NCI) Common
Toxicity Criteria for Adverse Events (CTCAE) will not be used for capturing or grading GVHD.  
The Glucksberg criteria will be followed in assessment of acute GVHD and the highest
grade will be recorded (Appendix D).  Chronic GVHD is graded based on clinical manifestations
of organ systems based on the National Institutes of Health (NIH) consensus criteria (8) and
Center for International Blood and Marrow Transplant Research (CIBMTR) grading guidelines
(Appendix E). GVHD will be assessed weekly until Day +100 while inpatient and at specific time
point per section 11.4 and 11.5.
12.0 ADVERSE EVENTS
An adverse event is any untoward medical occurrence associated with the use of a drug
in humans, whether or not considered drug related. An AE can therefore be any unfavorable and
unintended sign (including an abnormal laboratory finding), symptom, or disease (new or
exacerbated) temporally associated with the use of study intervention.
AE collection will begin on Day -14 through Day +30 post-transplant.
12.1 Criteria for Defining AE
The CTCAE, version 5.0, will be used to determine AE terms, definitions and grades for
AE reporting.  All appropriate treatment areas should have access to a copy of the CTCAE,
version 5.0.  A copy of the CTCAE version 5.0 can be downloaded from the CTEP web
site http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm.  
12.1.1 ‘Expectedness’: AEs must be documented as ‘Unexpected’ or ‘Expected’
for expedited reporting purposes.
STUDY00010785
Approval: 11/22/2022

Protocol 18-011
26
12.1.2 An Unanticipated AE is defined as one that is serious, unexpected, related
(definitely, probably) to the study drug, and suggests that the research
places subjects or others at a greater risk of harm (including physical,
psychological, economic, or social harm) than was previously known or
recognized.  
     12.1.3  Attribution of the AE:
•
Definitely Related – There is clear evidence to suggest a causal relationship, and other
possible contributing factors can be ruled out. The clinical event, including an abnormal
laboratory test result, occurs in a plausible time relationship to study intervention
administration and cannot be explained by concurrent disease or other drugs or chemicals.
The response to withdrawal of the study intervention (dechallenge) should be clinically
plausible. The event must be pharmacologically or phenomenologically definitive, with use
of a satisfactory rechallenge procedure if necessary.
•
Probably Related – There is evidence to suggest a causal relationship, and the influence of
other factors is unlikely. The clinical event, including an abnormal laboratory test result,
occurs within a reasonable time after administration of the study intervention, is unlikely to
be attributed to concurrent disease or other drugs or chemicals, and follows a clinically
reasonable response on withdrawal (dechallenge). Rechallenge information is not required to
fulfill this definition.
•
Possibly Related – There is some evidence to suggest a causal relationship (e.g., the event
occurred within a reasonable time after administration of the trial medication). However,
other factors may have contributed to the event (e.g., the participant’s clinical condition,
other concomitant events). Although an AE may rate only as “possibly related” soon after
discovery, it can be flagged as requiring more information and later be upgraded to “probably
related” or “definitely related”, as appropriate.
•
Unlikely to be related – A clinical event, including an abnormal laboratory test result, whose
temporal relationship to study intervention administration makes a causal relationship
improbable (e.g., the event did not occur within a reasonable time after administration of the
study intervention) and in which other drugs or chemicals or underlying disease provides
plausible explanations (e.g., the participant’s clinical condition, other concomitant
treatments).
•
Not Related – The AE is completely independent of study intervention administration,
and/or evidence exists that the event is definitely related to another etiology. There must be
an alternative, definitive etiology documented by the clinician.
12.2 Required AEs Collection and Entry to Study Database
All AEs from day-14 to day +30 post-transplant will be collected and documented in the
source document regardless of grade, attribution or expectancy.
Therapy for hematologic malignancies, with or without stem cell transplantation, is
associated with significant hematologic and non-hematologic toxicities.  These toxicities are
generally viewed as anticipated events of therapy. Grades 1 and 2 AEs that are expected will not
be entered into the study database.
Grade 3, 4 and 5 adverse events regardless of relationship, expectancy or attribution, will
be collected and entered into the study database.
STUDY00010785
Approval: 11/22/2022

Protocol 18-011
27
12.3Definition of Primary Engraftment Failure
Failure to achieve a neutrophil count >500/μL within 35 days of the stem cell infusion will
be defined as primary engraftment failure.    If primary engraftment failure occurs, an action to
obtain neutrophil recovery (such as the use of growth factors or stem cell boost) will be allowed.
Neutrophil count recovery will continue to be monitored in these subjects until they reach
statistical endpoint. Hospitalization (prolonged) due to engraftment failure would be SAE.
12.4 Serious Adverse Event and Unanticipated Adverse Events
An SAE is an AE that occurs and results in ANY of the following:
1.
Death.
2.
A life-threatening adverse drug experience.  The term "life-threatening" in the
definition of "serious" refers to an event in which the patient was at risk of death at the time of
the event; it does not refer to an event which hypothetically might have caused death if it were
more severe.
3.
Inpatient hospitalization or prolongation of existing hospitalization.   Emergency
room visits that do not result in admission to the hospital are not SAEs unless they meet one of
the other criteria noted.  Hospitalization for elective surgery or routine clinical procedures that are
not the result of an AE (e.g., initiation of conditioning, surgical insertion or revision of central
line) should not be recorded as an AE or SAE.  Hospitalization (prolonged) due to engraftment
failure would be SAE.
4.
A persistent or significant incapacity or substantial disruption of the ability to conduct
normal life functions.
5.
Important Medical Events (IMEs) that may not result in death, be life threatening, or
require hospitalization may be considered a serious adverse drug experience when, based upon
medical judgment, they may jeopardize the patient or subject and may require medical or surgical
intervention to prevent one of the outcomes listed in this definition (FDA, 21 CFR 312.32; ICH
E2A and ICH E6).
12.5Required Reporting of AEs and SAEs
12.5.1 Reporting Adverse Reactions and Unanticipated Problems to the IRB
In accordance with applicable policies of The Pennsylvania State University
Institutional Review Board (IRB), the PI will report to the IRB any harm experienced
by a subject or other individual, which in the opinion of the investigator are unexpected
and probably related to the research procedure. AEs of this nature as well as SAEs will
be reported to the IRB within 5 business days in accordance with the IRB policies and
procedures.
12.5.2 Reporting Adverse Reactions and Unanticipated Problems to the FDA
The sponsor investigator will be responsible for notifying the FDA of certain
unanticipated events.   Unexpected and related (possibly, probably or definitely) fatal
or life-threatening events require reporting to the FDA as soon as possible but no later
than 7 calendar days after study team’s notification of the event. A written follow up
must be provided when necessary by 15 calendar days after becoming aware of the
event.  Those SAEs that are not life threatening or fatal must be reported within 15
calendar days of becoming aware of the event.   
STUDY00010785
Approval: 11/22/2022

Protocol 18-011
28
Safety reports to the FDA must be submitted on a Medwatch Form FDA 3500A and
be accompanied by Form FDA 1571, Investigational New Drug Application (IND).
The type of report (initial or follow-up) should be checked in the respective boxes on
both forms. The submission must be identified as:
• “IND safety report” for 15-day reports, or
• “7-day IND safety report” for unexpected fatal or life-threatening suspected adverse
reaction reports, or
• “Follow-up IND safety report” for follow-up information.
The report must be submitted to an appropriate FDA Review Division that has the
responsibility to review the IND application under which the safety report is submitted.
FDA recommends that all sponsors submit safety reports electronically. Other means
of rapid communication to the respective review division’s Regulatory Project
Manager (e.g., telephone, facsimile transmission, email) may also be used.
SAEs and reportable events will be reported to the sponsor via MedWatch form
3500A within 24 hours of knowledge. Updates to the SAE should be made as
events change. SAEs will be collected until Day +30 for all subjects.
13.0 DATA REQUIREMENTS, COMPLIANCE AND QUALITY ASSURANCE
13.1
Confidentiality of Records:
Research related documents will be stored in the limited access, locked PSCI CTO.  
Institutional policy and guidance on requirements for managing clinical research data will be
followed, including the appropriate levels of safeguard to ensure the confidentiality, integrity and
availability of clinical research data.
13.2
Participant Consent Form:  
Prior to commencement of any research related activities, written, signed and dated
participant consent for the study protocol must be obtained.  A copy of the signed and dated
informed consent form must be provided to the research participant.  The original signed consent
form and additional consents will be maintained in the PSCI CTO. Copies will also be uploaded
in the participant’s Electronic Medical Record (EMR). The original signed consent form for
institutional Hematopoietic Stem Cell Transplant as part of standard of care will sent to PSH EMR
while the copy will be obtained and kept in the subject’s research binder in PSCI CTO.    
13.3 Data Collection and Maintenance:
Electronic data capture will occur via electronic case report forms in On-line Clinical Oncology
Research Environment (OnCore®). OnCore® is the primary data management system for clinical trials
activity at PSHCI.  OnCore® was developed by Forte, Inc., and is a highly secure, web-based,
customizable system that provides fully integrated clinical data management and protocol management
capabilities.  OnCore® houses regulatory tracking information, study management activity and clinical
data.  
13.4 Study Monitoring:
To ensure compliance with current federal regulations and the ICH guidelines, data generated
by this study must be available for inspection upon request by representatives of the FDA, national and
local health authorities, the Sponsor-Investigator and duly authorized representative of any entity
providing support for this trial. The study will be monitored by Penn State Cancer Institute Compliance

Program. The monitors will provide an independent review of the regulatory and subject records and
the data collected to assure compliance with the protocol, GCP, and applicable federal regulations. The
comprehensive monitoring will occur within 2 weeks after the first subject’s receives protocol therapy;
After the 1st monitoring visit, Interim Monitoring Visits will occur every 8 weeks for the first 3 subjects
enrolled then every 4 months thereafter; follow-up visit will be annually until study closure; If there
has been no treatment activity, monitoring visits must occur at a minimum of every 3 months. and ad-
hoc for any study based on findings. A Close-out Visit (COV) will be conducted no later than 3 months
after the final subject has completed the study, all data has been collected and all queries have been
resolved; or at the request of the Sponsor or designees.
13.5 Audit and Inspection
Applicable federal, state and local entities may request an audit or inspection at any time. The
PI will ensure all requested documentation is provided to auditors and inspectors, including appropriate
access to the study database, source documentation and Case Report Forms (CRFs).
13.6.   Protocol Non-Compliance and Departures
A protocol departure is any non-compliance with the clinical trial protocol, ICH GCP, or Federal
and local regulations.   The non-compliance may be either on the part of the subject, the PI or Sub-Is,
or the study site staff.  As a result of departures, corrective actions must be developed by the site and
implemented.   Reporting of protocol non-compliance to the IRB will be completed as directed in the
Penn State IRB Investigator Manual. Study subjects will be notified of any significant departures.  
Documentation of the departure and the notification discussion with the subject must be included in
the research record.
For the purpose of this protocol, any deviation in the administration of the study drug will be
deemed non-compliance.  Any modification to the conditioning regimen, post-transplant medication,
general assessments (laboratory assessments, physical exams, biopsy timelines, etc), and timelines will
be done for the purpose of standard medical management and will not be reported as protocol non-
compliance.   
13.7 Data Safety Monitoring Plan
The PSHCI Data and Safety Monitoring Committee (DSMC) will serve as the internal DSMB
for data and safety review for this protocol. The PI will continuously monitor study progress for safety
and will hold routine meetings with the study team and disease center personnel to review overall
conduct and progress of this study. The frequency of such discussions will be dependent upon accrual
to the trial and issues that arise. Study team and disease team meetings will cover accrual, AEs and
safety issues, response and overall progress of the trial.
Every three months, the PI will provide the PSHCI DSMC with reports showing the number of
subjects enrolled, SAE assessments, information on any protocol deviations or breaches of
confidentiality, response, if appropriate, and overall status of the trial. The PSHCI DSMC meets
regularly (currently every three months), as well as, on an ad hoc basis. Also, at the completion of
each dosing cohort, the cohort results must be presented to the committee before proceeding to the next
planned cohort. The PI will be asked for a report for the DSMC sufficiently in advance of annual IRB
renewal in order to include DSMC findings with annual IRB submission. AE reporting to the IRB will
occur in compliance with IRB guidelines. Unanticipated AEs, as well as, any significant literature
reporting developments that may affect the safety of subjects in this study will be reported to the IRB
as they arise. Unanticipated AEs will be reported to PSHCI DMSC simultaneously with the IRB
reporting.

13.8 Institutional Review Board Review and Approval:
This protocol, the informed consent document, relevant supporting information and all
types of patient recruitment and advertisement information must be submitted to the local IRB for
review and must be approved before the study is initiated. An amendment to remove a life-
threatening situation can by implemented by the PI prior to obtaining IRB approval by the site. In
such situations, the IRB must be notified immediately and the amendment forwarded to the IRB
for their consideration.
The PI is responsible for keeping their local IRB informed on the progress with study
renewal at least once a year. The PI must also keep the local IRB informed of any significant AEs,
per local institutional guidelines.
13.9 Record Retention
FDA regulations (21 CFR 312.62) require clinical investigators to retain all study-related
documentation, including source document and CRFs, long enough to allow the sponsor to use
the data to support marketing applications.  If this study is conducted under an IND, all records
must be maintained for:
• Two years after the FDA approved the marketing application, or

• Two years after the FDA disapproves the application for the indicating being studied, or
• Two years after the FDA is notified by the sponsor of the discontinuation of trials and that
an application will not be submitted.
The Sponsor Investigator will take measures to prevent accidental or premature destruction
of study documents.   For such studies, records will be retained for a minimum of seven (7) years
past official study termination.
14.0 STATISTICAL CONSIDERATIONS
14.1. Summary of Design: This is a single-arm phase II trial to study the effectiveness of the
proposed treatment (Clofarabine followed by HSCT with Post-Transplant Cyclophosphamide for non-
remission AML). The primary endpoints will be CR rate at day +30 post HSCT, as well as, feasibility,
safety and toxicity of the regimen. The secondary endpoints will be OS and DFS at year +1 after HSCT,
NRM by day +100 after HSCT, incidence and severity of acute and chronic GVHD and rate of
engraftment.
14.2.
Sample Size Justification and continuous monitoring for serious adverse effects:
Based on published papers on CloBu4 regimen in non-remission AML, it is estimated that the
remission rate for this new treatment is >90%. The remission rate for the standard treatment is <56%16.
This study intends to show the superiority of the proposed treatment and to reject the null hypothesis
that the remission rate for the proposed treatment is 56% or lower. The proposed sample size of 20
subjects achieves this with 80% power at 5% type one error.
Enrollment will begin at 30 mg/m2 to analyze any unexpected and related grade 4-5 organ toxicities as
defined in Section 12.2. If the trial is stopped due to excessive toxicities, then dose de-escalation to 20
mg/m2 will occur for the next cohort of participants. For each subject, the observation period is from
day -14 through post-transplant day 30. For this trial, the adverse effects will be continuously
monitored as patients are enrolled. We shall use a Bayes procedure developed by Chen, C., and
Chaloner, K.17 We will stop the trial when the toxicity rate exceeds 20% with a posterior probability
of 80% and a margin of no more than 5%. The trial will start the clofarabine dose of 30 mg/m2 and
use the following stopping rule: if any grade 4 or 5 non-hematological toxicities which are unexpected
and related occur in 2 of the first 3 subjects, or 3 of 6, 4 of 9, 5 of 12, 6 of 16 or 7 of 19, then clofarabine
will be reduced to 20 mg/m2 with the next subject enrolled. Once the dose modification has occurred,
re-escalation of clofarabine to 30mg/m2 is not permitted. If the dose de-escalates to 20 mg/m2, the
following same stopping rule will be used to ensure subject safety. If any grade 4 or 5 non-
hematological toxicities which are unexpected and related occur in the 2 of  the first 3, or 3 of 6, 4 of
9, 5 of 12, 6 of 16 or 7 of 19, subjects at the 20 mg/m2 dose level, the trial will be stopped.  
The non relapse mortality (NRM) will be observed from start of treatment through post-transplant
day 100. We will stop the trial when the day-100 NRM rate exceeds 25% with a posterior probability
of 80%. This leads to the stopping rule that the trial will be stopped when NRM occurs in greater than
or equal to 3 of 6, 4 of 9, 5 of 12, 6 of 16 or 7 of 19 patients.
14.3.   Statistical Analysis Plan: The remission of each patient on the trial will be carefully
documented and the 30-day remission rate calculated, which will be compared to the 56% remission
rate of standard treatment using exact binomial test. For the secondary endpoints of progression free
survival and overall survival, Kaplan-Meier Methods will be used to estimate the survival curves. The
one-year relapse rate, one-year overall survival probability and one-year disease free survival will be
provided with 95% confidence interval. Key regimen related toxicities will be described as reported.
Time to engraftment will be captured by retrieving the cell counts data after transplant and will be
recorded as a standard method. Relapse rate at 2 years will be calculated as the cumulative incidence

of relapse, as death a competing event.
14.4
Sample Size and Accrual Rate:  Anticipated enrollment rate is 1-2 participants
per month.  Total sample size is 20. Given this accrual rate, expected duration of enrollment for
this study is 24 months.
14.5    Reporting and Exclusions
Evaluation of toxicity: All patients will be evaluable for toxicity as defined in Section 11.0 from
day -14 pre-transplant to day +30 post HSCT.
Evaluation of response: CR rate at day +30 post HSCT will be calculated and toxicity and
engraftment will be assessed in order to evaluate response.
