STUDY SUMMARY 
HAPCORD:  
Principal Investigator: Mari Hashitate Dallas, MD 
IND/IDE: 16036 
Brief Overview: In this study, participants with high-risk hematologic malignancies undergoing 
hematopoietic cell transplantation (HCT), who do not have a suitable human leukocyte antigen 
(HLA)-matched related/sibling donor (MSD), matched unrelated donor (MURD) or killer-
immunoglobulin receptors (KIR) ligand mismatched haploidentical donor identified, will receive 
an combined haploidentical and umbilical cord blood transplantation (UCBT) using a reduced 
intensity conditioning (RIC) preparative regimen.  Patients who have a suitable KIR ligand 
mismatched haploidentical donor will be preferentially enrolled in available haploidentical 
protocol (i.e. HAPNK1).  Those with a suitable HLA matched sibling or unrelated donor 
identified may be eligible for participation if the donor is not available in the necessary time.  
Participants must be ≤ 21 years old and with sufficient multi-organ function as specified in 
protocol.  
The assessments and follow-up evaluations noted in the protocol follow the St. Jude standard 
operating procedures (SOP) for all recipients of allogeneic HCT.  
Intervention: Combined haploidentical graft with an unrelated umbilical cord blood graft using 
a reduced intensity preparative regimen. 
Brief Outline of Treatment Plan:  The preparative regimen includes total lymphoid irradiation 
(TLI) (8 Gy), fludarabine (150 mg/m2), cyclophosphamide (60mg/kg), melphalan (140 mg/m2) 
and thiotepa (10mg/kg).   TLI will be administered in 4 fraction at 200 cGY/fraction over 3 days 
on day -9 to day -7, fludarabine will be given once a day at 30 mg/m2 for five days on day -8 to 
day -4, cyclophosphamide will be given once a day at 60mg/kg for one day on day -6, thiotepa 
will be given twice a day at 5 mg/kg for one day on day -3, and melphalan will be given once a 
day for 2 days on day -2 and day-1.  Post-transplantation immunosuppression with tacrolimus 
will begin on day -2 and MMF on day 0. Haploidentical donor product will be infused on day 0 
and day +1.  Cord Blood infusion will occur on day +2.  G-CSF may start on day +3, but may be 
held at the discretion of the attending physician.  
Objectives:  
Primary objective  
 Estimate the incidence of engraftment by day +42 post-transplant for participants with 
high-risk hematologic malignancies undergoing a reduced intensity conditioning (RIC) 
hematopoietic cell transplantation (HCT) using a haploidentical donor combined with a 
unrelated umbilical cord blood (UCB) donor. 
Secondary objectives: 
 Estimate the incidence of malignant relapse, event-free survival, and overall survival at 
one-year post-transplantation. 
 
Estimate the incidence and severity of acute and chronic graft versus host disease 
(GVHD). 
 
Estimate the incidence of transplant related mortality (TRM) and transplant related

morbidity in the first 100 days after transplantation. 
Exploratory Objectives 
 
Assess the relationship between pre-transplant minimal residual disease (MRD) with 
transplant outcomes. 
 
Record 
immune 
reconstitution 
parameters, 
including 
chimerism 
analysis, 
quantitative lymphocyte subsets, T cell receptor excision circle (TREC) and 
spectratyping.  Immunophenotyping and functional assays of T, B and NK cells and 
lymphocytes will also be evaluated.  
 
Characterize the recovery of Gamma Delta T cells after HCT, including T cell 
receptor analysis, phenotyping and functional analysis.  
 
Characterize influenza infection during HCT by monitoring viral isolates and key 
host factors associated with influenza susceptibility. 
Hypotheses/Estimates:  
Of the patients with hematologic malignancies requiring allogeneic HCT, approximately 30% will 
have a suitable matched related/sibling donor (MSD) and another 30% will have a matched 
unrelated donor (MURD) identified.1-4 The lack of an adequate MURD for 25-60% of eligible 
pediatric recipients, and the lengthy duration of the donor search process in those with high risk 
of relapse have prompted investigators to use an alternative source of HSC, namely UCB.3 
Although UCB has been shown to be a suitable source of HSC, initial studies suggested UCBT is 
associated with increase incidences of TRM when compared to recipients of MSD or MURD.5, 6 A 
pilot study in adults that combined haploidentical and an unrelated UCBT using a RIC resulted in a 
rapid engraftment with minimal GVHD and durable remission.7 Here, we propose to investigate 
the outcomes of pediatric patient with high-risk malignancies undergoing a combined 
haploidentical and UCBT using a RIC regimen at St. Jude Children’s Research Hospital.  The 
primary objective of the study is to estimate the rate of engraftment by day +42 post-transplant 
in patients undergoing a combined haploidentical and UCBT using a reduced intensity 
preparative regimen.  Secondary aims will assess overall survival, event-free survival, risk of 
relapse, graft versus host disease (GVHD), transplant related mortality (TRM), transplant 
related morbidity, and immune reconstitution. 
 
Criteria for Evaluation:    
Safety Evaluation  
 The primary measures of safety will be the rate of therapy related death and the rate of 
severe graft versus host disease. 
 Ongoing assessment of toxicity will be done using the NCI CTC version 3. Acute GVHD 
will be evaluated using the standard grading criteria (Appendix B). 
Efficacy  
 Neutrophil and platelet engraftment will be determined using the parameters put forth by 
the Center for International Blood and Marrow Registry.  Assessments will be made upon 
review of daily complete blood count and serial chimerism studies. 
 BM studies for disease status evaluation will be performed at approximately 28 days, 100 
days, and yearly post-transplant.  
 Acute GVHD will be assessed using the standard grading criteria put forth by Prezpiorkia 
et al 1995. Chronic GVHD will be assessed using the NIH Consensus Criteria for 
Chronic GVHD 2005 (Appendix B).

Human Subjects: The risks to subject are primarily related to the infusion and the 
conditioning regimen.  The allogeneic stem cells may induce serious and possibly fatal 
disorders such as GVHD, veno-occlusive disorder and post-transplant lymphoproliferative 
disease.  Because of the required conditioning, recipients are at high-risk for serious and 
possibly life-threatening infection, bleeding, and anemia.  Adverse events will be treated, 
monitored, and reported appropriately. 
Possible benefits of participation include obtaining and/or sustaining disease remission.  In 
addition, there is the possibility of psychological benefit from knowing participation has helped 
researchers gain more understanding about the efficacy of UCBT. 
Alternatives to participation are identified as chemotherapy, research treatment if available, 
and/or supportive therapy. 
The possible benefits, alternatives to participation, and side effects, including that there may be 
unknown side effects of treatment, are detailed in lay language within the respective informed 
consent documents.

2.0 BACKGROUND AND RATIONALE 
2.1 Overview 
Allogeneic HCT has become a widely accepted curative therapy for many hematologic 
malignancies that cannot be cured with chemotherapy alone.8, 9 Studies have 
demonstrated that HCT is a potentially curative therapy for patients with CML, AML, 
ALL and MDS.10-13 Furthermore, patients with non-Hodgkin or Hodgkin’s lymphoma 
who recur after an autologous HCT may be successfully treated with an allogeneic 
HCT.14, 15 
Of the patients with hematologic malignancies requiring allogeneic HCT, approximately 
30% will have a suitable matched related/sibling donor (MSD) and another 30% will have 
a matched unrelated donor (MURD) identified.1-4 The lack of an adequate MURD for 25-
60% of eligible pediatric recipients, and the lengthy duration of the donor search process 
in those with high risk of relapse have prompted investigators to use an alternative source 
of HSC, namely UCB.3 Recent comparative studies report no significant difference in OS 
in patients undergoing UCBT compared to MURD HCT.16-20  Thus, the number of 
patients undergoing UCBT has rapidly increased over the past 10 years. In the pediatric

population, UCB is now the most common source of HSC in unrelated donor transplant. 
However, the limited number of progenitor cell in the UCB unit result in delayed and 
unpredictable count recovery.  The delayed neutrophil recovery predisposes patients to 
infection and recipients of UCB is associated with increase incidences of TRM when 
compared to recipients of MSD or MURD.5, 6 A pilot study in adults that combined 
haploidentical and an unrelated UCBT using a RIC resulted in a rapid engraftment with 
minimal GVHD and durable remission.7 St. Jude has gained considerable expertise with 
haploidentical HCT in children 21-28 and we propose to investigate the outcomes of 
pediatric patient with high-risk malignancies undergoing a combined haploidentical and 
UCBT using a RIC regimen at St. Jude Children’s Research Hospital. 
2.2 Umbilical Cord Blood Transplantation (UCBT) 
2.2.1 Historical Background: 
The use of UCB as a clinical source of HSC was first considered in the late 
1960’s when UCB from eight donors were pooled and infused into a 16 year old 
male with acute lymphocytic leukemia (ALL).29  Although full reconstitution was 
not observed, there was evidence suggesting transient mixed chimerism. 
Thereafter, additional studies were performed that suggested that if adequate 
numbers of HSC could be collected; UCB has the potential for long-term 
reconstitution.  In 1989 the first successful matched sibling UCBT was performed 
for a child with Fanconi anemia. In 1995, the International Cord Blood Transplant 
Registry (ICBTR) reported the results of the first 44 matched sibling UCBT 
demonstrating UCB contained sufficient number of hematopoietic progenitors to 
reliably engraft transplant recipients after a myeloablative conditioning regimen.30  
The first successful unrelated UCBT in a pediatric patient occurred at Duke 
University in 1993.31, 32 In 1996, Kurtzberg et al and Wagner et al simultaneously 
published the unrelated UCBT experiences at Duke and Minnesota, 
respectively.32, 33 These initial studies showed the median time to neutrophil 
recovery was 22 and 24 days, respectively.  Combining the 43 patients, 88% 
engrafted, 54% had Grade II-IV GVHD and 9% had Grade III-IV GVHD.  The 
OS at 100 days was 53%.  Together, these studies suggested that UCB is a 
suitable alternative source of allogeneic HSC for pediatric patients.  
In nearly every large single center or registry analysis of outcomes after UCBT, 
cell dose is identified as an important factor influencing the incidence and rate of 
hematopoietic recovery, risk of TRM, and probability of survival.  Furthermore, 
data suggest that infusion of two partially HLA-matched UCB units, which 
always augments the graft cell dose, is safe and may improve neutrophil recovery 
and survival.  To determine whether the infusion of two UCB units enhances 
survival, the Blood and Marrow Transplant Clinical Trials Network (BMTCTN) 
proposed a multi-center randomized trial in 2006.  Preliminary data suggest that 
patients receiving double unit UCBT have a higher risk for acute GVHD albeit a 
lower risk for relapse.  However, until data clearly demonstrate a survival 
advantage, double UCBT is currently only recommended for those patients who 
do not have an adequate single unit.34

Lastly, in the past decade, large comparative studies evaluating the outcomes of 
transplantation using UCB versus other HSC sources have been performed. 
Reports demonstrate that the incidence of GVHD was lower in patients 
undergoing UCBT compared to HLA-matched bone marrow (BM) recipients.  
Furthermore, recent studies that include long-term analysis demonstrate that 
outcomes are similar for patients undergoing transplantation using MURD or 
UCB sources.14-18, 25 Thus, UCBT should be considered as a viable options for 
patients with high-risk malignancies.16-20, 35 7-11, 25 
2.2.2  Cell Dose Threshold and Interaction with HLA match 
Cell dose remains one of the single most important determinants of a successful 
UCBT.36-38 Numerous clinical studies have shown that the total nucleated cell 
(TNC) dose and the CD34+ cell dose in the UCB graft are highly correlated with 
neutrophil and platelet engraftment as well as the incidence of graft failure and 
early TRM.3, 37, 39, 40 The first Eurocord Registry report by Gluckman et al, 1997, 
demonstrated that among 527 patients undergoing UCBT, the most important 
predictor in outcome was the infusion of ≥ 3 x 107 TNC per kilogram body 
weight.36, 41 Moreover, adult recipients had increased TRM by day 180 compared 
to children (56% versus 32%), and deaths were related to the number of cells 
infused, with patients who received ≤ 1 x 107 TNC/kg having a 75% probability 
of death compared to 30% for those who received ≥ 3 x 107 TNC/kg.  Rubinstein 
et al, 1998, published the New York Blood Center experience with 562 patients 
undergoing UCBT and similarly demonstrated a strong correlation between the 
number of leukocytes infused and engraftment.38 Thus, the collective data point to 
improved outcome of UCBT for patients receiving a larger number of CD34+ 
cells.  Delayed engraftment has also been correlated with HLA mismatch at 
greater than 2 loci, but recent studies have suggested that the impact of HLA 
disparity on survival can be partially overcome by increasing cell dose.42 
Combined, these studies identified a minimum threshold for cell dose and HLA 
matching which lead to a significant reduction in TRM after UCBT.  Although the 
exact threshold criteria for each degree of HLA mismatch is not know, the 
principle for the dose algorithm is clear.34, 43, 44 
2.2.3  Role of Double UCBT 
For most adults and large children, a single UCB unit that meets the cell dose 
requirement is not available.  To overcome this obstacle, investigators at the 
University of Minnesota began infusing two partially HLA-matched units to 
augment cell dose. They found that engraftment was achieved more rapidly and in 
a higher proportion of patients than the previous cohort who received only a 
single UCB unit.45 Preliminary evidence suggests that double unit UCBT may be 
associated with a decreased risk of relapse in patients with good disease control at 
the time of transplant, but is also associated with a increased incidence of mild to 
moderate acute GVHD compared to single UCBT.46,47, 48 Currently, it is unclear 
whether double UCBT offers any benefit other than extending the application of 
UCBT by achieving the cell dose threshold.49 Until data clearly demonstrate a 
survival advantage, double UCBT is currently only recommended for those 
patients who do not have an adequate single unit.50 An adequate single unit is

defined as: ≥ 3.0 x 107 nucleated cells/kg for 6/6 HLA-matched units, ≥ 4.0 x 107 
nucleated cells/kg for 5/6 HLA-matched units and ≥ 6.0 x 107 nucleated cells/kg 
for 4/6 HLA-matched units.48, 50, 51Despite adequate cell dose, patients undergoing 
double UCBT continue to have delayed engraftment compared to MSD and 
MURD HCT.  
2.2.4  UCBT Results 
Engraftment: Most studies report the time to hematopoietic recovery after UCBT 
is delayed with the median time to neutrophil recovery ranging between 20 - 30 
days and the incidence of engraftment after single UCBT ranges from 65-92%.31, 
33, 37, 38, 40, 41, 52-60 Studies have consistently demonstrated the rate and incidence of 
engraftment after UCBT is slower than bone marrow transplantation (BM), 
dependent on cell dose and the threshold for cell dose depends on HLA match 
grade.  
GVHD: The first report from the New York Blood Center experience by Rubinstein 
et al indicated that GVHD after UCBT occurred at a lower rate compared to those 
with MURD transplantation.38 Thereafter, Rocha et al published the first 
comparative analysis between UCBT and MURD transplantation in pediatric 
patients that substantiated the claim that acute and chronic GVHD were less 
common in recipients of UCB.18 In larger studies, the incidence of acute GVHD is 
reported to range from 33-44% and 11-22% for grades II-IV and III-IV acute GVHD 
respectively. The incidence of chronic GVHD ranges from 0-25%.37, 38, 57, 59, 60  
Survival: Nearly all studies demonstrate a significant relationship between UCB cell 
dose and survival and the reported probability of survival after single UCBT ranges 
from 18-78%.16, 20, 40, 45, 47, 51, 61-65 One of the largest reports from the Center for 
International Blood and Marrow Transplant Research (CIBMTR) by Eapen et al in 
2007 compared the outcomes of 785 pediatric patients with acute leukemia who 
received a UCBT (n=503) or an unrelated BMT (n =282).  The most notable finding 
was that UCBT compared favorably to an 8/8 allele-matched unrelated BMT.  In 
comparison with allele-matched BMT, the 5 year disease free survival (DFS) was 
similar to that after either one or two antigen mismatched UCBT and possibly higher 
after 6/6 allele-matched UCBT.16 These and other studies support that UCB should 
be considered an acceptable source of HSC grafts in the absence of an HLA-
matched donor. 16, 17, 20, 37, 38, 40, 45, 47, 51, 57, 59-66 
2.3 Haploidentical HCT 
2.3.1 
Haploidentical HCT Background 
Haploidentical donors are another viable alternative donor source when a MSD or 
MURD are not available.  Also, family members are highly motivated, easily 
accessible, and readily available for most patients.  Along with other institutions, 
St. Jude has shown haploidentical HCT to be an effective therapy for patients with 
hematologic malignancies.67-71 Due to the high potential for GVHD with the 
degree of HLA mismatch seen in haploidentical HCT, most haploidentical grafts 
are extensively T-cell depleted (TCD) prior to infusion.72  Significant progress 
was achieved when high cells dose of CD34+ cells were infused after high-

intensity conditioning.70 It has been well established that prompt engraftment with 
rapid immune reconstitution can be achieved with CD34+ enriched haploidentical 
cells, purified by positive (CD34+) and negative (CD3- lectin agglutination) 
selection.73,74 
Building on the initial studies above, St. Jude has gained considerable expertise with 
haploidentical HCT in children.21-26, 28, 75 Over the past decade (2001-2010), more 
than 220 mismatched related donor HCT have been performed at St. Jude.  Initially, 
most haploidentical HCT performed in this institution were for patients with 
relapsed and refractory hematologic malignancies, however as it became a more 
successful therapeutic maneuver, it has become a primary transplant option for 
patients who lack a well matched donor.27   
Recent studies suggest that alloreactive NK cells play a role in graft versus 
leukemia (GVL) and influence outcomes of patients with hematologic 
malignancies after haploidentical HCT.76-83 The NK cell alloreactivity depends on 
the balance of signals mediated through activating and inhibitory KIRs on the NK 
cell.  In patients who received haploidentical HCT for high risk leukemia at 
SJCRH the presence of KIR mismatch dramatically reduced the risk of relapse.24 
Thus, patients with high risk hematologic malignancies who lack an HLA-
matched donor but have a KIR mismatched haploidentical donor available, would 
be expected to benefit from haploidentical HCT. 
2.3.2  Rationale for immunomagnetic TCD of hematopoietic progenitor cell graft  
Donor T cells in the haploidentical graft play a major role in mediating GVHD, 
with as few as 3 x 104 T cells/kg can cause GVHD.84  TCD allows for a HSC graft 
with very low T cell content, such that the risk of GVHD is decreased. T cells can 
be removed from the HSC graft by direct removal of T cells (negative selection) 
or positive selection of CD34+ progenitors. St. Jude has had success using either 
method of TCD in haploidentical donor transplantation.  
In this study, CD34+ selection by CliniMACS will be the used for TCD of the 
haploidentical graft.  Although positive selection allows for extensive TCD, the 
graft is devoid of other important cell populations such as NK cells and myeloid 
cells such as dendritic cells and monocytes.85, 86  In addition, this extensive degree 
of TCD has significant negative effects on the time to donor immune competency.  
Donor T cells are critical for reconstituting the allogeneic host immune system, 
and lymphocyte recovery is an important determinate of outcome post-
transplant.87, 88 Transplants that employ TCD result in elimination of most 
memory T cells, leading to protracted immune dysfunction- an effect that 
becomes more severe with higher intensity conditioning regimens.21, 89 This 
results in an increased rate of opportunistic infections. Indeed, viral infections are 
the most common cause of death of children receiving haploidentical 
transplants.90 The majority of these infections occur within the first 6 months 
following transplantation, when T cell immunity is the lowest.91 Reconstitution of 
immunity can be partially restored by therapeutic infusions of donor cytotoxic 
lymphocytes.87, 92-94 However, in addition to requiring significant resources and 

HAPCORD 6

expertise, the cells must be engineered or selected for specific infections - making 
this approach impractical for broad application.95   
A more ideal approach would be to infuse a cell product with diverse lymphocyte 
repertoire capable of effectively recognizing a variety of pathogens, as well as 
malignant cells without additional GVHD risk. One strategy would be to target 
naïve T cells for lymphocyte depletion.  Naïve T cells are fully matured but do not 
proliferate until they encounter their receptor specific ligand.96  After ligand 
recognition, there is activation of proliferative signals that initiates a marked, 
antigen-specific cell expansion and inflammatory response. While many of these 
naïve T cells will undergo apoptosis after the initial response, others are rescued 
from immune retraction and will persist as memory T cells.  Once generated, 
memory cells persist in the circulation as a diverse cell pool that is critical for 
long-term infection control.97  Furthermore, memory T cells are capable of more 
rapidly responding to future infectious challenges.98 
The isoform of the leukocyte common antigen, CD45RA, selectively identifies 
naïve T cells.  Human studies have shown that sorted donor CD45RA+ naïve T 
cells are far more alloreactive than all memory subsets tested.99 In animal models, 
naïve T cells, are potent inducers of GVHD.95 Moreover, in similar models, 
lymphocyte infusions specifically depleted of CD45RA+ naïve T cells do not 
cause GVHD.100  Conversely, CD45RA- memory T cells do not cause physical or 
histologic evidence of GVHD. Among CD4+ T cells, the CD45RA- subset has 
equivalent “helper” functions as CD45RA+ cells in the generation of alloreactive 
cytotoxic T cells.101  Further, it is the CD45RA- memory cells that are responsible 
for aiding B-cell differentiation and antibody production.   
After demonstrating promising pre-clinical results, selective CD45RA depletion 
in patients undergoing HCT are underway, including two at SJCRH (RADIANT 
and HAPNK1). Depletion of CD45RA+ cells by magnetic beads has been shown 
to be a feasible and effective method for depletion of naïve T cells, with up 
greater than 3-log depletion in number of CD45RA+ cells  (Data provided by 
Miltenyi).  Furthermore, experiments were performed in the HAL to confirm and 
qualify the CD45RA+ depletion procedures.  HSC products were obtained from 
G-CSF mobilized normal donors by apheresis. The HPC, Apheresis products were 
depleted of CD45RA+ cells following a procedure provided by Miltenyi Biotech. 
Briefly, the cells were incubated with the CD45RA microbead reagent followed 
by washing to remove unbound beads. The labeled cells were then applied to the 
CliniMACS device (Depletion Tubing Set) and the CD45RA+ cells removed 
using the Depletion 3.1 program. Flow cytometric analysis before and after 
depletion was performed following procedures provided by Miltenyi Biotech. The 
results of the experiments are presented in the table below. An example flow 
cytometric analysis of CD3+ cells is also included.  We hypothesize combining a 
CD34+ enriched product (HPC, Apheresis 1) along with a CD45RA+ depleted 
product (HPC, Apheresis 2) will provide a HSC graft with good stem cell content 
(3-5 x 106 CD34+ cells/kg) and a useful memory T cell fraction without additional 
GVHD risk to the recipients on this trial.

2.4 Rationale for RIC Preparative Regimen 
RIC regimens have the potential to improve the outcomes of allogeneic HCT by 
decreasing the acute TRM.102-104  TLI was initially developed with curative intent in 
patients with Hodgkin Lymphoma, and it was its use in these patients that led to the 
discovery of TLI’s alteration of T-cell specific immune responses.  Years of pre-clinical 
research on TLI have shown that the use of TLI promotes engraftment and reduces 
GVHD.105 This work was then followed up with therapeutic trials in humans with 
hematologic malignancy, which showed that conditioning with TLI and ATG alone allowed 
a high rate of durable donor engraftment, a low rate of GVHD, and preservation of evidence 
of graft versus malignancy effect, in patients who received HLA-matched related or 
unrelated donor grafts.106, 107  We have significant institutional experience using TLI-based 
regimens for allogeneic transplantation (n=29 as of June 2012).  Importantly, TLI-based 
conditioning has allowed successful salvage HCT in patients who failed previous allo-HCT.  
Nine patients have received TLI-based conditioning with haploidentical donor HCT after 
experiencing previous allograft failure (3 had primary graft failure, 4 had initial engraftment 
with acute rejection, and 2 had late graft failure).  The same haploidentical donor was 
utilized in 5 of the 9 salvage HCT, with 4 patients receiving a new (haploidentical) donor.  
Eight of 9 patients (89%) experienced durable engraftment at a median of 12 days (range 10 
– 27 days).  The remaining patient had primary graft failure due to progressive disease.  This 
experience indicates that TLI is effective for facilitation of engraftment, even in patients 
receiving a mismatched haploidentical donor graft and with a history that indicates a very 
high risk of graft failure.  There is additional published experience from Germany in which 
TLI – given as a single 7Gy fraction – was utilized in 14 adult and pediatric patients for 
reconditioning after graft failure/rejection.108 Despite most of the patient having 
haploidentical donors, engraftment was obtained in all evaluable patients.  In addition, TLI 
was well tolerated in this pediatric population that had recently received another (typically 
myeloablative) preparative regimen.  Finally, 10 patients in Chile received TLI-containing 
preparative regimen, similar to our proposed regimen, as a part of their haploidentical donor 
preparative regimen.109 TLI was given as a single dose at 7Gy.  Nine out of 10 patients 
experienced rapid donor engraftment, with relapse as the cause of the one primary graft 
failure.  Six of 10 patients were alive and disease free at one year, 3 died of progressive 
disease, and one of infection. 
2.5 Rationale for Study 
In the past 20 years, over 20,000 UCBT have been performed worldwide and over 
400,000 UCB units have been stored in more than 100 UCB banks.32, 39, 110 The main 
practical advantages of using UCB as an alternative source of HSC are (1) rapid 
availability, (2) absence of donor risk, (3) relative ease of procurement, (4) absence of 

HAPCORD 8 
 
Initial version, dated: 08/22/14

Protocol document date: 08/22/14 
 
donor attrition, (5) very low risk of transmissible infectious diseases and (5) low risk of 
acute GVHD despite HLA mismatch.  Furthermore, UCB is particularly beneficial for 
patients of ethnic and racial minority descent for whom adult marrow and blood donors 
often cannot be identified.32, 38, 39, 110 According to data from the National Marrow Donor 
Program (NMDP) donor registry, the probability of finding an 8 out of 8 HLA-matched 
donor is 51% for Caucasians, 30% for Hispanics, 20% for Asians and 17% for African 
Americans.  Since patients who do not have a MURD can undergo a mismatched 
unrelated UCB transplantation and achieve similar results, the number of patients 
undergoing UCBT has rapidly increased over the past 10 years. The CIBMTR reports 
that from 2004 to 2008, UCB is now the most common graft source and BM is no longer 
the most common unrelated donor graft source for patients 20 years or less.  Furthermore, 
in 2007 and 2008, 46% of all unrelated donor transplantations used UCB grafts for 
patients 20 years or less. 
Patients who do not have an appropriate MSD or MURD donor available in a timely manner 
often undergo transplantation using an alternative HSC source from UCB or haploidentical 
donors.  Often, the type of donor is chosen based on various factors related to urgency of 
transplantation, patient, disease, and transplant-related factors as well as the center’s 
experience. Although a prospective randomized clinical trial is the accepted standard to 
compare different treatment regimens, the feasibility and acceptability of such a clinical 
trial is problematic and has not been performed.  However, retrospective studies 
comparing the two donor sources have demonstrated no difference in survival.  
The Eurocord group performed a retrospective study comparing the outcome of pediatric 
patients with high-risk ALL undergoing either UCBT or haploidentical HCT.  Patients 
had received either haploidentical (n=118) or UCB (n=341) transplantation in Eurocord 
centers between 1998 and 2004. The median follow-up was 56 and 24 months for 
haploidentical and UCBT patients, respectively. Failure of engraftment was significantly 
higher following UCBT than after haploidentical HCT (23% vs. 11%, p=0.007). In a 
multivariate analysis, relapse incidence was higher in haploidentical HCT recipients 
compared to UCBT (relative risk 1.7, p=0.01), but TRM and DFS were not significantly 
different. In conclusion, in pediatric patients with ALL, UCBT is associated with inferior 
rate of engraftment, higher incidence of grades II–IV acute GVHD and lower incidence 
of relapse compared to haploidentical HCT; however, there was no difference in terms of 
TRM and DFS. Therefore, in the absence of an HLA-identical donor, both strategies were 
reported to be suitable options to treat a child with high-risk ALL.  
At our institution, patients who do not have an appropriate MSD or MURD donor available 
often undergo a haploidentical HCT.  Studies at St. Jude have shown the presence of 
natural killer (NK) KIR mismatch in a haploidentical donor dramatically reduced the risk 
of relapse in patients who received HCT for high-risk leukemia.24, 25 KIR mismatch is 
predictive of NK alloreactive effects in haploidentical HCT.24, 25, 78, 80 Thus, patients who 
have a KIR mismatch haploidentical donor will be enrolled into a haploidentical HCT 
with NK infusion (HAPNK1).  However, approximately one-third of all patients posses 
all relevant KIR ligands and will not have a KIR mismatched haploidentical donor. These 
patients will require an alternate donor for best clinical outcome.  Patients who require an 
alternative donor HSCT and do not have a KIR mismatched haploidentical donors are 
likely to benefit most from UCBT for best clinical outcome. Contradictory results have 

HAPCORD 9

been reported on the effect of KIR matching in UCBT.  The European group reported 
KIR-ligand incompatible UCBT improved DFS (hazards ratio = 2.05, p = .0016) and OS 
(hazards ratio = 2.0, p = .004) and decreased relapse incidence (hazards ratio = 0.53, p = 
.05).111 However, the Minnesota group found no advantage using KIR matching in 
UCBT.112 Currently, the effect of KIR matching in UCBT is controversial and UCB 
selection based on KIR matching is not recommended. 
To date, UCBT01, the first UCBT protocol at SJCRH has accrued 9 patients, with 5 
patients receiving a single UCB unit and 4 patients receiving two UCB units.  One patient 
on the observational arm died due to TRM before day 100.  All 8 remaining patients 
engrafted however, 2 patients would be categorized as significant graft delay/failure with 
engraftment after day +42.  One patient engrafted at day 49 and another at day 51.  The 
mean time to neutrophil engraftment is 28±13 days, (range; 12-51).  Thus, despite 
optimizing HLA match and cell dose, engraftment continues to be significantly delayed 
in patients undergoing UCBT.   
In order to abrogate the increased TRM and complication from graft failure and delayed 
engraftment, we propose to provide a combined haploidentical donor with a single 
UCBT. A pilot study reported the results of 45 adults with a mean age of 50 yrs (range; 
20-69) who underwent a RIC regimen using fludarabine, melphlan and ATG for high risk 
malignancies.  The graft consisted of a single UCB with minimum cell dose of 1.0 x 107 
TNC/kg along with a TCD haploidentical donor graft.  GVHD prophylaxis was with 
MMF and tacrolimus.  All patients engrafted and the mean time to neutrophil engraftment 
was 11 days and platelet engraftment was 19 days.  Chimerism analysis demonstrated 
that the predominant haploidentical graft early after HCT is replaced by the UCB graft by 
day 100.  The risk for GVHD was not increased with the reported cumulative incidence 
of acute GVHD of 25% and chronic GVHD of 5%.  
2.6 Minimal residual disease (MRD) 
Despite the fact that the vast majority of patients with high-risk leukemia are in clinical 
remission prior to HCT, approximately 30-40% ultimately relapse after HCT.  Detection 
of MRD and early intervention may improve the clinical outcome.  Detection of leukemic 
cells that are below the limits of detection by standard morphologic examination allow 
early interventions when the patients are MRD positive but still in remission.  By using 
flow cytometry and polymerase chain reaction (PCR) amplification of antigen receptor 
genes in tandem, investigators at our institution have been able to conduct MRD studies 
in 80 consecutive ALL cases.113 Results of St. Jude institutional studies have shown that 
detection of MRD by immunologic techniques at any point in the treatment course is a 
powerful predictor of relapse in children with ALL.113-115 However, other studies suggest 
that eradication of all acute leukemia cells may not be a prerequisite for cure.116, 117 
Similar to conventional-dose therapy, controversy also exists on the implication of MRD 
in the setting of HCT.  Unlike CML, there is a paucity of data on the natural history of 
AML and ALL patients who have MRD after HCT, and how pre-transplant MRD levels 
influence post-transplant outcomes.118, 119  It is unclear whether they are also at greater 
risk of relapse; and whether further pharmacological or immunologic therapy indeed 
prolongs survival and increases cure rates.  Thus, for the participants who are enrolled in 
this protocol who are unable to proceed to post-transplant immunomodulatory protocols, 
we will gather the MRD information together with hematopoietic chimerism in a 

HAPCORD 10

descriptive manner to study the relationship between MRD and chimerism in this large 
cohort of patients. The knowledge gained from this study should allow their future 
application to guide therapeutic interventions. 
2.7 Rationale for the evaluation of immune reconstitution after UCBT 
Delayed immune reconstitution is a major complication after HCT and impacts the 
overall survival in patients. Recent studies demonstrate that the rate and quality of 
immune recovery after UCBT is an important predictor of overall outcomes.  
Unfortunately, the rate of immune reconstitution directly correlates with the number of 
infused HSC and UCB patients have delayed immune reconstitution secondary to the 
limited numbers of HSC.70, 120-122  Though transplantation with multiple unrelated UCB 
units has been used as a strategy to increase the total number of cells infused, the effect 
on immune reconstitution is not clear.  In this study, we propose to monitor the rate of 
immune reconstitution after single and double UCBT. De novo generation of thymic 
derived T cells is critical in reconstituting a functional immune system, thus newly 
derived thymic T cell will be monitored by measuring the concentration of TREC DNA 
by quantitative PCR in the peripheral blood of transplant recipients.   Furthermore, the 
time to recovery (defined as the median time to reach the normal value of age-matched 
healthy individual) of CD3+, CD4+, CD8+, CD19+ and CD56+ cells in patients undergoing 
UCBT will be investigated. Various subsets of T cells will be investigated including 
naïve, memory, central memory, effector memory, regulatory T cells as well as naïve and 
memory B cells.  Functional measures of immune recovery will be examined by T cell 
proliferative response to nonspecific and specific antigen and NK lytic function.  Antigen 
specific T cell response to various infections will be monitored in patients over time.  
Using a direct ex vivo, single-cell-based assay for clonotypic analysis of human epitope-
specific receptor, we will characterize T cell response to specific infections.  
Studies demonstrate that the rate of engraftment of a single unit was significantly 
enhanced after addition of a second unrelated UCB unit.  It is clear that infusion of a 
second UCB unit facilitates the engraftment of the dominant unit, however, the 
mechanism has yet to be investigated.  Preliminary data from the Dallas laboratory 
suggest that dendritic cells and regulatory T cells play a critical role in facilitating 
engraftment in the BM and thymus.123, 124 Data obtained from this study addresses a key 
question regarding the immunological mechanism for enhanced engraftment by 
facilitating cells. Furthermore, published studies consistently report that after a double 
UCBT, cells from only one of the UCB unit engraft.  However, recent results from a 
multi-institutional clinical trial have demonstrated that small number of patients who 
undergo a double UCBT have evidence of mixed chimerism in the BM from the two 
UCB units one-year after HCT.   Furthermore, studies performed at the Fred Hutchinson 
Cancer Research Center, demonstrated that single-unit dominance after double-unit 
UCBT coincides with NK cell dose and a specific CD8+ T-cell response against the non-
engrafted unit.125

Choose the unit with highest HLA match (6/6, 5/6 then 4/6)  
- Matching at HLA typing at HLA-A, B antigen level and DRB1 allele 
level. 
- The patient and the UCB unit(s) must be matched at least 4 of 6 loci. 
- The unit must meet cell dose threshold of 1.0 x 107 TNC/kg 
 
If > one unit is available for a HLA match grade, chose unit based on: 
- DRB1: Matching at DR takes preference, followed by  
 SELECT OPTIMAL UNIT WITHIN SAME HLA MATCH   
DR typing takes preference 
Prefer homozygous over bidirectional mismatch 
Choose the largest TNC unit.  
If TNC is similar (± 0.5 x 107 TNC/kg) 
Utilize HLA C matching if available 
Utilize higher resolution molecular typing if available. 
Utilize CD34+ cell count if available. 
CHOOSE UNIT WITH HIGHEST HLA MATCH  
 Minimum of 4 of 6 matching to the patient at

- Locus of mismatch: A unit that is homozygous at the locus of mismatch 
should be chosen over a unit that is bidirectional at the locus of mismatch, 
even if the latter unit is larger, followed by 
- Cell Dose: Choose the unit containing the greatest TNC. 
 
mismatch and cell dose  (± 0.5 x 107 TNC/kg), choose the unit with: 
- HLA match by higher resolution molecular typing, if data available 
- HLA-C antigen/allele level typing, if data available 
- Larger CD34+ cell dose, if data available 
- UCB banks located in the United States are preferred.  
4.3.2  UCB Unit Exclusions  
4.3.2.1 Unit fails to meet cell dose threshold criteria  
Cell dose is < 1.0 x 107 TNC per kilogram recipient weight.  
4.3.2.2 Fails screening 
 
Any UCB units without full maternal testing and negative results for hepatitis 
A, B, C, Human Immunodeficiency Virus (HIV), and Human T-lymphotropic 
virus-1 (HTLV-1) viruses. Any additional available virology results on the unit 
itself will be reviewed but are not mandated, complete or always available. The 
majority of UCB units will come from banks that operate under the guidelines 
outlined in 21 CFR 1271 and the Guidance for Industry: Minimally Manipulated, 
Unrelated 
Allogeneic 
Placental/Umbilical 
Cord 
Blood 
Intended 
for 
Hematopoietic Reconstitution for Specified Indications.  All NMDP banks must 
fulfill this requirement.  Foreign banks may have differing screening procedures 
even if they are American Association of Blood Banks (AABB) or Foundation 
for the Accreditation of Cellular Therapy (FACT) accredited.  It is important to 
clarify the screening process employed, and additional plasma may be requested 
if additional testing is needed to fulfill Eligibility Determination requirements.  
Currently UCB units are available for use under federal IND.  The NMDP holds 
an IND for use, and a few of the older banks hold their own IND. There is no 
need to adjust for nucleated RBCs when considering TNC.  The UCB unit(s) 
must be present at St. Jude prior to the start of conditioning. 
4.3.3  UCB Graft Preparation 
Preparation for administration will take place in the Human Applications Lab 
(HAL) in the Department of Bone Marrow Transplantation and Cellular Therapy 
(BMTCT) of St. Jude using established Standard Operating Procedure (SOP).  
UCB units must be prepared for infusion in a manner that assures high cell 
recovery, maintains cellular viability, and avoids contamination.  When unit 
volume and Dimethyl sulfoxide (DMSO) concentration are not considered 
clinically prohibitive, and the wash procedure is deemed by the PI to have a 
potential adverse impact on the UCB unit, a reconstitutive thawing procedure may 
be utilized.  In this case, the unit is thawed, and then reconstituted at least 1:1 with 
an infusion grade solution (Dextran/albumin).  In general, a wash is desired, 
particularly when there are concerns about volume, DMSO dose, red cell replete 

HAPCORD 19 
 
Initial version, dated: 08/22/14

product, etc.  For UCB products to be washed, a modified version of the New 
York Blood Center’s Placental Blood Thaw Procedure will be used.  Briefly, the 
unit will be thawed and diluted; the plasma will then be expressed away after 
gentle centrifugation.  In each case, 1-2 mL of the final product will be removed 
for testing prior to infusion. 
4.4 Haploidentical Donor Graft 
4.4.1  Haploidentical Donor Selection 
If more than one family member donor is acceptable, then donor selection will be 
based on the preference of the primary transplant attending.  Factors in selection 
will include donor-recipient matching of CMV serology, donor-recipient red 
blood cell compatibility, degree of HLA matching, size of the potential donor, 
previous use as a donor, presence of donor-specific antibody, and overall health of 
the potential donor. 
Donor eligibility for cell collection will be determined through the guidelines 
outlined in 21 CFR 1271 and the Guidance for Industry: Eligibility Determination 
for Donors of Human Cells, Tissues, and Cellular and Tissue-Based Products 
(HCT/Ps).  Potential donors will undergo an initial screening process that will 
include at least a complete physical exam, history and testing for relevant 
communicable diseases.  Physical exams to evaluate donor candidacy will be 
conducted by a non-Department of BMTCT physician (St. Jude or non-St. Jude).  
For subsequent therapeutic cell collection procedures, if a complete screening 
procedure has been performed within the previous 6 months, an abbreviated donor 
screening procedure may be used for these repeat donations.  The abbreviated 
screening procedure must determine and document any changes in the donor’s 
medical history since the previous donation that would make the donor ineligible, 
including changes in relevant social behavior. 
If a donor is determined to be ineligible, the donor is not automatically excluded. 
Part 21 CFR 1271.65 (b)(1)(i) allows use of ineligible donors who are first or 
second degree blood relatives. In this situation, the physician will document the 
necessity of using the ineligible donor by providing a statement of "Urgent 
Medical Need" as explained in the 21 CFR 1271.3 (u).  The cell therapy products 
will be labeled as required in 21 CFR 1271.65 (b)(2). Recipients or their legal 
guardians will be informed of the use of an ineligible donor. 
Please see Departmental SOP 30.05 “Determination of Eligibility and Suitability 
for Stem Cell and Therapeutic Cell Allogeneic and Autologous Donors” for 
additional information. 
4.4.2  Haploidentical Donor Mobilization and Donor HSC Graft Collections  
A G-CSF mobilized peripheral blood stem cell (PBSC) product (identified as 
HPC, Apheresis) is the preferred progenitor cell graft source.  Our desired target 
goal will be 3-5 x 106 CD34+ cells/kg.  This number of cells will be necessary to 
provide an adequate graft, following the various ex vivo manipulations, for 
prompt reconstitution. Two days of collection are typically needed to achieve this 
goal.  However, on rare occasions, additional days may be necessary.  Donors will 

HAPCORD 20 
 
Initial version, dated: 08/22/14 
 
IRB approval date: 10/17/14 
Protocol document date: 08/22/14 
 
undergo a standard HSC mobilization regimen consisting of 6 days of G-CSF 
given subcutaneously at 10 mcg/kg. The graft will be collected by leukapheresis 
on days 5 and 6.  The HPC, Apheresis product will typically be collected and 
infused fresh, however there may be patients or logistical situations that require 
the HPC, Apheresis product to be collected early, processed, and stored frozen. 
The decision to use a fresh versus frozen HPC, Apheresis will be made by the PI 
and/or primary transplant attending based on patient and donor factors, as well as 
potential scheduling conflicts.

**Do not start apheresis if platelet count < 50,000/mm3 or hemoglobin of < 12.5 g/dL pre-phresis 
 
The dose of G-CSF may require modification based on the complete blood counts 
(CBC).  If the donor’s white blood count (WBC) is >75.0 x 106/ml the dose of 
cytokine administered will be reduced.  The guidelines for dose modification can 
be found in the St. Jude Children's Research Hospital Department of BMT and 
CT SOP 30.06.00 “The practice for the evaluation, preparation and care of 
allogeneic and autologous donors mobilized with growth factor.” Ongoing 
updates of this document can be located at the following St. Jude intranet website: 
http://home.web.stjude.org/bone_marrow/ 
The daily leukapheresed volumes for HPC, Apheresis collection is generally 3–4 
total blood volumes based on CD34+ cell counts.  Two additional days of 
leukapheresis may be performed at the physician’s discretion (no more than 4 
total) to reach the cell dose target, however, this is expected to be rare.   
Leukapheresis may be terminated early upon request of donor, or when deemed 
medically necessary per the judgment of the treating sub-investigator physician or 
PI.  All HPC, Apheresis products will be collected as per FACT guidelines. 
Donors will be monitored during the period of the mobilization and leukapheresis 
procedure with appropriate laboratory evaluation (Appendix D). 
If we are unable to collect the minimum dose of 2 x 106 CD34+ cells/kg of 
recipient weight from the first donor, and the recipient has not yet initiated the 
preparative regimen, then an alternative family member may be used if he/she 
fulfills all donor criteria described in section. If the donor is unwilling or unable 
to complete the mobilization process or leukapheresis procedure, a BM product 
may be used.  The BM product will be processed using the same cell selection 
methodology on the CliniMACS device.

4.5 Graft Preparation 
Graft evaluation and preparation will take place in the Human Applications Laboratory 
(HAL) in the Department of Bone Marrow Transplantation and Cellular Therapy 
(BMTCT) using established SOP.  
The initial HPC, Apheresis product(s) will be TCD using the investigational CliniMACS 
device and CD34 Microbead reagent as directed by the manufacturer (Miltenyi Biotech).  
See section 5.2 for additional CliniMACS device information.  Briefly, HPC, Apheresis 
products from the mobilized donor will be initially assessed in the HAL and stored 
overnight at 4oC.  The next morning, the product will be washed to remove platelets and 
adjusted to an appropriate cell concentration for incubation with the CliniMACS CD34 
Microbead reagent in the manufacturer provided media.  The cells will be washed to 
remove unbound microbeads.  These cells will be applied to the CliniMACS device and 
the enrichment will be performed using the program “CD34 Enrichment 2.1” as 
described by the manufacturer. 
After enrichment is complete, the cells will be washed and resuspended in an infusion 
grade solution. The graft product will be enumerated and assessed for viable CD34+ cell 
and CD3+ T cell content by flow cytometry. The processed HPC, Aphersis CD34 
Enriched product will be infused fresh or frozen for future use after completion of release 
testing and evaluation. Cryopreservation will be performed per SOPs of the HAL.  Target 
cell doses are listed in the following table:

Once the target dose is obtained for the CD34+ enriched product, one additional day of 
apheresis will be performed.  This HPC, Apheresis product will be processed for 
CD45RA+ depletion using the investigational CliniMACS device as directed by the 
manufacturer (Miltenyi Biotech). See section 5.1 for additional CliniMACS device 
information.  Briefly, HPC, Apheresis products from the mobilized donor will be initially 
assessed in the HAL and stored overnight at 4oC.  The next morning, the product will be 
washed to remove platelets and adjusted to an appropriate cell concentration for 
incubation with the CliniMACS CD45RA Microbead reagent in the manufacturer 
provided media.  The cells will be washed to remove unbound microbeads. These cells 
will be applied to the CliniMACS device and the depletion will be performed using the 
"Depletion 3.1" software as described by the manufacturer.  When combined with the 
CD34+ enriched product, the target CD34+ dose will be 3-5 x 106/kg.  There is no CD3+ 
cell target dosing on the CD45RA+ depleted product, however release criteria of the 
product will include at least a ≥ 2.00 log10 depletion of CD45RA+ cells.

4.6 Additional Progenitor Cell Graft Administration 
Infusion of an additional HSC graft from the original or an alternative haploidentical donor 
may be performed for participants when clinically indicated for graft failure, poor immune 
reconstitution, or poor hematopoietic recovery. The use of and content of a conditioning 
regimen is left to the discretion of the PI and/or primary transplant attending such that the 
most appropriate therapy is chosen for the clinical situation. 
The HSC graft will typically be obtained by apheresis (HPC, Apheresis) and be infused 
fresh.  The target dose for this additional CD 34+ infusion is ≥5 x 106 cells/kg.  If the 
participant has quiescent or active BOOP, acute Grade III-IV GVHD, or any other reason 
that a severely T-cell depleted graft may be indicated, then a graft from the donor processed 
on the CliniMACSTM device using either CD34+ selection (using established SOPs) or CD3+ 
depletion methodology may be utilized. The boost target dose for these patients is ≥10 x 
106 CD34+cells/kg with a CD3+ cell/kg dose of ≤ 0.5 x 105 CD3+ cells/kg.   
4.7 Donor Lymphocyte Infusions 
Donor lymphocyte infusions (DLI) may be administered from the haploidentical donor 
for decreasing donor chimerism, serious viral reactivation or infection, or any evidence of 
disease (from any level of MRD to frank relapse).  The DLI collected may be collected as 
a whole blood unit donation or by leukapheresis. If the DLI is collected by standard 
phlebotomy, the volume to be collected would be approximately 300 ml whole blood.  If 
the DLI is collected by leukapheresis, the amount to be processed would be 
approximately 2 total blood volumes. 
Prior to administration of DLI, the immunosuppression should be withdrawn and the 
recipient should have no active GVHD.  The initial dose will typically be 2.5 x 104 
CD3+/kg.  Subsequent doses will be administered at approximately 2 to 4-week intervals 
with escalating doses of T cells if no moderate or severe GVHD occurs with the prior 
DLIs.  The typical initial dose escalation for patients on this protocol is presented in the 
following table: 
DLI DOSE AND SCHEDULE 
DLI 
Dose 
Comments 
Initial Dose 
2.5 x 104 CD3+/kg 
Approximately 2-4 week interval 
If no moderate or severe GVHD 
Dose #2 
5.0 x 104 CD3+/kg 
Dose #3 
10.0 x 104 CD3+/kg 
Although this algorithm will be appropriate for a majority, the treating transplant 
attending physician may alter the dose and/or interval of DLI based on response to 
previous DLI, the severity of the clinical situation, and the condition of the patient.  There 
is a low threshold for providing an initial dose of 2.5 x 104 CD3+/kg.  DLI at this dose 
level have not been associated with GVHD.  Therefore, DLI may be initiated for any 
chimerism less than 100% in a patient who is off immune suppression.  The risk of 
GvHD increases with increasing doses.  In the last 5 years, no patient has developed 
moderate or severe GVHD after haploidentical DLI dosed at 5 x 104 CD3+/kg, though 
mild GVHD has occasionally occurred.  Doses of 10 x 104 CD3+/kg should be considered 
to carry a risk of severe GVHD.  Therefore dose escalation to this level must incorporate 
the appropriate risk/benefit analysis by the treating transplant physician.

4.8 Quality Assurance of Cellular Products 
Quality assurance for cell products is overseen by independent Quality Assurance 
personnel who authorizes release of all products. Only trained stem cell processors will 
process the cell products. A labeling and product tracking system is in place to ensure 
that the correct cells are infused into the research participant. 
Assays of cell numbers and immunophenotyping will be performed both before cell 
processing and at critical stages of the process.  These values will be recorded according 
to SOP of the HAL.  All TCD products will be tested for viability, sterility (culture and 
Gram stain), and the presence of endotoxin. Culture and endotoxin results are not 
available before infusion of cell products. If the gram stain is positive, the research 
participant/parent and/or guardian will be informed of this event and of the risks of 
proceeding prior to infusion.  Positive results will be investigated as per the variance 
procedures of the HAL.  The IRB and FDA will be notified, if at any time after infusion, 
cell product was determined to be contaminated or endotoxin results exceed release 
limits.  
4.9  Immunosuppressive Therapies  
4.9.1  EBV post-transplant lymphoproliferative disease (PTLPD) prophylaxis  
Rituximab at 375 mg/m2 may be given intravenously as clinically indicated.  For all 
patients, monitoring peripheral blood EBV DNA and prophylaxis and treatment 
will be according to BMTCT standard guides and/or at the discretion of the 
treating physician as clinically indicated based on ongoing EBV copy levels and 
clinical assessment. If a positive selection methodology would be used for a 
haploidentical HCT infusion, rituximab would not be administered, unless 
otherwise clinically indicated. 
4.9.2  Tacrolimus  
Tacrolimus to start on day -2. Preferably, start tacrolimus as a continuous infusion 
until patient engrafts and able to reliably obtain therapeutic levels.   Maintain 
therapeutic levels according to institutional guidelines and practice.  May modify 
dose for decreased chimerism or positive MRD.  May convert to oral dosing when 
patient is tolerating oral and has a normal gastro-intestinal transit time.  If no 
evidence of GVHD, begin to wean by approximately 10% every week on day 100, 
and discontinue around day 180 and no sooner than 6 months post transplant.   
4.9.3  MMF 
MMF to start on day 0 at 15mg/kg intravenously TID or every 8 hours. May convert 
to oral dosing when patient is tolerating oral and has a normal gastro-intestinal 
transit time.  Adjust dose as clinically indicated. If no evidence of GVHD, MMF can 
be discontinued on day +45 or on/about 7 days after engraftment, whichever is later.  
May hold for decreased chimerism or positive MRD. Continue MMF if patient has 
no evidence of donor engraftment on bone marrow evaluation and contact PI of 
results.  
4.9.4  Methylprednisolone* 
Methylprednisolone may be used for treatment of acute GVHD*.  (2mg/kg divided 
every 12 hours intravenously is suggested as initial therapy for patient with active

acute GVHD requiring systemic therapy)  If no response after 7 days, treat with a 
second line agent according to SOP.  Methylprednisolone at 1-5 mg/kg/day can be 
used for management of pre-engraftment immune reaction as described below in 
4.10* 
*Use of methylprednisolone and dosing are recommendations and variance in 
medication, dosing and frequency can occur due to the participant’s current 
clinical condition and will not be noted as protocol deviations. 
4.10 Management of Pre-engraftment Immune Reaction 
A well recognized clinical entity consisting of skin rash, fever, loose stools and 
respiratory distress has been noted to occur prior to engraftment among UCB patients, 
generally between day 7 and 21. This clinical syndrome likely involves cytokine 
activation, and though clinically similar to acute or hyperacute GVHD, it appears to be a 
distinct entity, “pre-engraftment syndrome.” This syndrome is often controlled with brief 
steroid bursts, thus avoiding a commitment to extended steroid exposure.  Patients should 
be monitored carefully for this syndrome. If patients have moderate to severe symptoms 
as described above and alternative etiologies (i.e., infection) have been excluded or are 
being appropriately evaluated, patients may be treated with steroids. Recommendation of 
methylprednisolone is provided.  
The usage of methylprednisolone described here is a recommendation, and variations in 
medication, dosing and/or frequency can occur due to the participant’s current clinical 
condition and will not be noted as protocol deviations. 
4.10.1  For 
patients 
not 
on 
steroid 
therapy 
when 
the 
syndrome 
occurs: 
methylprednisolone should be given at 1 mg/kg intravenously once a day for three 
days. If symptoms have abated, steroids should be stopped. If symptoms persist, 1 
mg/kg can be continued through six days then stopped if symptoms have abated. 
If symptoms persist for more than six days, the patient should be considered to 
have acute/hyperacute GVHD and should be treated with prolonged steroids as 
deemed appropriate. Please alert PI if patient is requiring methylprednisolone for 
> 6 days for engraftment syndrome.  
4.10.2 For patients already on steroids for other reasons when the syndrome occurs: 
methylprednisolone should be given at a dose of 3-5 mg/kg intravenously (max 
dose 500 mg) every 12 hours for maximum of 48 hours, followed by a rapid taper 
to 1 mg/kg intravenously every 12 hours. Patients should be weaned after 
response as tolerated. Please alert PI if patient is requiring methylprednisolone for 
> 6 days for engraftment syndrome.  
4.11 Growth Factors 
4.11.1  Granulocyte colony-stimulating factor (G-CSF) 
G-CSF may start on day +3 at 5 mcg/kg/day intravenously or subcutaneously until

5.0 MEDICATION INFORMATION 
5.1 Cyclophosphamide (Cytoxan) 
Source 
& 
Pharmacology  
Cyclophosphamide is a nitrogen mustard derivative.  It acts as an alkylating 
agent that causes cross-linking of DNA strands by binding with nucleic acids 
and other intracellular structures, thus interfering with the normal function of 
DNA. It is cell cycle, phase non-specific. Cyclophosphamide is well 
absorbed from the GI tract with a bioavailability of >75%.  It is a prodrug 
that requires activation. It is metabolized by mixed function oxidases in the 
liver to 4-hydroxycyclo-phosphamide, which is in equilibrium with 
aldophosfamide. Aldofosfamide spontaneously splits into nitrogen mustard, 
which is considered to be the major active metabolite, and acrolein. In 
addition, 4-hydroxycy-clophosphamide may be enzymatically metabolized to 
4-ketocyclophosphamide and aldophosfamide may be enzymatically 
metabolized to carboxyphosphamide that is generally considered inactive.  
Cyclophosphamide and its metabolites are excreted mainly in the urine. Dose 
adjustments should be made in patients with a creatinine clearance of <50 
ml/min. 
Formulation 
and Stability  
Cyclophosphamide is available in vials containing 100, 200, 500, 1000 and 
2000mg of lyophilized drug and 75 mg mannitol per 100 mg of 
cyclophosphamide.  Both forms of the drug can be stored at room 
temperature. The vials are reconstituted with 5, 10, 25, 50 or 100 ml of 
sterile water for injection, respectively, to yield a final concentration of 20 
mg/ml.  Reconstituted solutions may be further diluted in either 5% dextrose 
or 0.9% NaCl containing solutions.  Diluted solutions are physically stable 
for 24 hours at room temperature and 6 days if refrigerated, but contain no 
preservative, so it is recommended that they be used within 24 hours of 
preparation.

Toxicities 
Dose limiting toxicities of cyclophosphamide includes BM suppression and 
cardiac toxicity.  Cardiac toxicity is typically manifested as congestive heart 
failure, cardiac necrosis or hemorrhagic myocarditis and can be fatal.  
Hemorrhagic cystitis may occur and necessitates withholding therapy. The 
incidence of hemorrhagic cystitis is related to cyclophosphamide dose and 
duration of therapy. Forced fluid intake and/or the administration of mesna 
decreases the incidence and severity of hemorrhagic cystitis.  Other toxicities 
reported commonly include nausea and vomiting (may be mild to severe 
depending on dosage), diarrhea, anorexia, alopecia, immunosuppression and 
sterility.  Pulmonary fibrosis, SIADH, anaphylaxis and secondary neoplasms 
have been reported rarely.

5.2. Thiotepa (Thioplex by Immunex) (TESPA, TSPA) 
Source 
& 
Pharmacology  
Thiotepa is a cell-cycle nonspecific polyfunctional alkylating agent.  It 
reacts with DNA phosphate groups to produce cross-linking of DNA strands 
leading to inhibition of DNA, RNA and protein synthesis.  Thiotepa is 
extensively metabolized in the liver to metabolites that retain activity, 
primarily triethylene-phosphoramide (TEPA).  The main route of 
elimination is via the urine, mainly as metabolites; the elimination half-life 
of the thiotepa is 2.5 hours, and that of TEPA is 17.6 hours. 
Formulation 
and Stability 
Thiotepa is supplied in single-use vials containing 15 mg of lyophilized 
thiotepa, 80 mg NaCl and 50 mg NaHCO3.  The intact vials should be 
stored under refrigeration and protected from light.  Each vial should be 
reconstituted with 1.5 ml of sterile water for injection to yield a 
concentration of 10 mg/ml.  Further dilution with sterile water for injection 
to a concentration of 1 mg/ml yields an isotonic solution; if larger volumes 
are desired for intracavitary, intravenous infusion, or perfusion therapy, this 
solution may then be diluted with 5% dextrose or 0.9% NaCl containing 
solutions.  The 10 mg/ml reconstituted solution is chemically stable when 
stored in the refrigerator for up to 5 days, however, it is recommended that 
solutions be prepared just prior to administration since they do not contain a 
preservative.  Reconstituted solutions should be clear to slightly opaque: the 
solutions may be filtered through a 0.22 micron filter to eliminate haze. 
Supplier 
Commercially available; manufactured by Immunex. 
Toxicities 
Dose limiting toxicity is myelosuppression.  The leukocyte nadir may occur 
at any time from 10 to >30 days.  Other toxicities include pain at the 
injection site, nausea and vomiting, anorexia, mucositis, dizziness, headache, 
amenorrhea, interference with spermatogenesis, and depigmentation with 
topical use.  Allergic reactions, including skin rash and hives, have been 
reported rarely.  Rare cases of apnea, hemorrhagic cystitis, and renal failure 
have occurred.  Thiotepa is mutagenic, carcinogenic, and teratogenic in 
animals.  Pregnancy category D.

5.3 Fludarabine (Fludara) 
Source 
& 
Pharmacology  
Fludarabine phosphate is a synthetic purine nucleoside analog and acts by 
inhibiting DNA polymerase, ribonucleotide reductase and DNA primase by 
competing with the physiologic substrate, deoxyadenosine triphosphate, 
resulting in inhibition of DNA synthesis. It can also be incorporated into 
growing DNA chains as a false base and interfere with chain elongation and 
halt DNA synthesis. Fludarabine is rapidly dephosphorylated in the blood 
and transported intracellularly by a carrier-mediated process. It is then 
phosphorylated intracellularly by deoxycytidine kinase to the active 
triphosphate form.  ~23% of the dose is excreted as the active metabolite in 
the urine (with dosages of 18-25 mg/m2/day for 5 days).  Renal clearance 
appears to become more important at higher doses, with approximately 41-
60% of the dose being excreted as the active metabolite in the urine with 
dosages of 80-260 mg/m2. 
Formulation 
and Stability 
Fludarabine is supplied in single-dose vials containing 50 mg fludarabine as 
a white lyophilized powder and 50 mg of mannitol.  The intact vials should 
be stored under refrigeration.  Each vial can be reconstituted by adding 2 ml 
of sterile water for injection resulting in a final concentration of 25 mg/ml. 
Because the reconstituted solution contains no antimicrobial preservative, the 
manufacturer recommends that it should be used within 8 hours of 
preparation.  The solution should be further diluted in 5% dextrose or 0.9% 
NaCl prior to administration. 
Supplier 
Commercially available. 
Toxicities 
The major dose-limiting toxicity of fludarabine is myelosuppression.  Nausea 
and vomiting are usually mild.  Side effects reported commonly include 
anorexia, fever and chills, alopecia and rash.  Neurotoxicity can be 
manifested by somnolence, fatigue, peripheral neuropathy, mental status 
changes, cortical blindness and coma and is more common at high doses.  
Neurotoxicity is usually delayed, occurring 21-60 days after the completion 
of a course of therapy and may be irreversible.  Side effects reported less 
commonly include diarrhea, stomatitis, increased liver function tests, liver 
failure, chest pain, arrhythmias and seizures.  Pulmonary toxicity includes 
allergic pneumonitis characterized by cough, dyspnea, hypoxia and 
pulmonary infiltrates.  Drug induced pneumonitis is a delayed effect, 
occurring 3-28 days after the administration of the third or later course of 
therapy.  Administration of corticosteroids usually results in resolution of 
these symptoms.

Pharmacology  
Melphalan, a derivative of nitrogen mustard, is a bifunctional alkylating 
agent.  Its chemical name is 4-[bis(2-chloroethyl)amino]-L-phenylalanine, 
and it has a molecular weight of 305.20.  Melphalan is active against tumor 
cells that are actively dividing or at rest.  Its cytotoxicity is thought to be due 
to inter-strand cross-linking with DNA, probably by binding at the N7

position of guanine.  Melphalan is highly protein bound and does not 
penetrate well into the cerebral spinal fluid. Elimination half-life after 
intravenous administration in adults is approximately 75 minutes. 
Elimination appears to be primarily by chemical hydrolysis, but caution 
should be used in patients with renal impairment.  Plasma concentrations of 
melphalan after oral administration are highly variable, possibly due to 
incomplete absorption, variable “first pass” hepatic metabolism or rapid 
hydrolysis. Area under the plasma concentration-time curves for orally 
administered melphalan is approximately 60% of intravenously administered 
melphalan in adult studies.  
Formulation 
and Stability  
Available as 2 mg tablets for oral administration. This medication is stable at 
room temperature until expiration date on the packaging.  Intravenous 
formulation is supplied as 50 mg freeze dried glass vial. Each 50 mg vial is 
supplied in a carton containing a 10 ml vial of sterile diluent. Lyophilized 
melphalan should be stored at controlled room temperature and protected 
from light. Each vial is marked with its expiration date. The melphalan for 
injection must be reconstituted immediately prior to infusion by rapidly 
adding the contents of the diluent vial (10 ml) to the freeze dried powder 
with a 20 gauge or larger sterile needle and immediately shaking vigorously 
until a clear solution is obtained.  This results in a 5 mg/ml solution.  The 
dose should then be diluted in 0.9% sodium chloride for injection to a final 
concentration of not greater than 0.45 mg/ml. The resulting admixture should 
be infused over a minimum of 15 minutes.  The infusion should be 
completed within 60 minutes of reconstitution.  Do Not Refrigerate the 
Reconstituted Melphalan.  
Supplier 
Commercially available 
Toxicities 
Melphalan is cytotoxic and caution should be used in handling and preparing 
the solution or administering the tablets. Use of gloves is recommended, and 
if contact with skin or mucosa occurs, immediately wash thoroughly. Second 
cancers such as acute non-lymphocytic leukemia, myeloproliferative 
syndrome, and carcinoma have been reported in patients taking melphalan 
alone or in combination with other chemotherapy or radiation. Melphalan 
causes suppression of ovarian function in premenopausal women, with a 
significant number of patients having amenorrhea. Testicular suppression 
(reversible and irreversible) has been reported.  The most common adverse 
reaction is myelosuppression. Irreversible bone marrow failure has been 
reported. Gastrointestinal side effects reported include nausea/vomiting, 
diarrhea and oral mucosa ulceration.  Hepatic toxicity has occurred, 
including veno-occlusive disease.  Acute hypersensitivity reactions occur in 
about 2.4% of patients, and can include anaphylaxis. Hypersensitivity 
reactions were characterized by urticaria, pruritus, and edema.  Some 
patients exhibited tachycardia, bronchospasm, dyspnea and hypotension that 
responded to antihistamines and corticosteroids. Other side effects that have 
been reported include skin ulceration or necrosis at injection site, vasculitis, 
alopecia, hemolytic anemia, pulmonary fibrosis, and interstitial pneumonitis.

Pharmacology  
Mesna is a synthetic sulfhydryl (thiol) compound. Mesna contains free 
sulfhydryl groups that interact chemically with urotoxic metabolites of 
oxaza-phosphorine derivatives such as cyclophosphamide and ifosfamide. 
Oral bioavailability is 50%. Upon injection into the blood, mesna is oxidized 
to mesna disulfide, a totally inert compound.  Following glomerular 
filtration, mesna disulfide is rapidly reduced in the renal tubules back to 
mesna, the active form of the drug.  Mesna and mesna disulfide are excreted 
primarily via the urine. 
Formulation 
and Stability 
Mesna is available in 2 ml, 4 ml and 100 ml amps containing 100 mg/ml of 
mesna solution.  The intact vials can be stored at room temperature.  Mesna 
may be further diluted in 5% dextrose or 0.9% NaCl containing solutions.  
Diluted solutions are physically and chemically stable for at least 24 hours 
under refrigeration.   
Supplier 
Commercially available 
Toxicities 
Mesna is generally well tolerated.  Nausea and vomiting, headache, diarrhea, 
rash, transient hypotension and allergic reactions have been reported.  
Patients may complain of a bitter taste in their mouth during administration. 
Mesna may cause false positive urine dipstick readings for ketones.   
Dosage 
and 
Administration 
Mesna is generally dosed at approximately 25% of the cyclophosphamide 
dose.  It is generally given intravenously prior to and again at 3, 6 and 9 
hours following each dose of cyclophosphamide.

Pharmacology 
G-CSF is a biosynthetic hematopoietic agent that is made using recombinant 
DNA technology in cultures of Escherichia coli. G-CSF stimulates 
production, maturation and activation of neutrophils. In addition, 
endogenous G-CSF enhances certain functions of mature neutrophils, 
including phagocytosis, chemotaxis and antibody--dependent cellular 
cytotoxicity. 
Formulation 
and Stability 
G-CSF is supplied in vials containing 300 and 480 mcg of G-CSF at a 
concentration of 300mcg/ml. The intact vials should be stored under 
refrigeration.  The vials can be left out of refrigeration for 24 hours, but 
should be discarded if left at room temperature for longer periods of time.  
G-CSF can be drawn up into tuberculin syringes for administration and 
stored under refrigeration for up to 7 days prior to usage.  G-CSF can be 
further diluted for intravenous infusion in 5% dextrose.  Do not dilute in 
saline---precipitate may form. If the final concentration of this product is <15 
mcg/ml, it is recommended that albumin be added to a final concentration of 
2mg/ml (0.2%) to minimize adsorption of the drug to infusion containers and 
equipment.

5.7  Mycophenolate mofetil (MMF, CellCept) 
Source 
& 
Pharmacology  
MMF is hydrolyzed to mycophenolic acid (MPA), an immunosuppressive 
agent. MPA inhibits B and T-cell proliferation, T-cell synthesis, and 
antibody secretion by potent, noncompetitive reversible inhibition of inosine 
monophosphate dehydrogenase (IMPDH) in the purine biosynthesis 
pathway. Inhibition of IMPDH results in a depletion of guanosine 
triphosphate and deoxyguanosine triphosphate, important intermediates in 
the synthesis of lymphocyte DNA, RNA, proteins and glycoproteins. Oral 
formulations of MMF are rapidly and extensively absorbed when given on an 
empty stomach.  Aluminum and magnesium-containing antacids and food 
decrease absorption of MMF.  MMF is rapidly hydrolyzed to the active 
metabolite (MPA) after oral or intravenous administration.  Free MPA is 
conjugated in the liver by glucuronyl transferase to inactive mycophenolic 
acid glucuronide (MPAG) that is excreted in the urine and feces.  Time to 
peak plasma concentration is 0.8–1.3 hours, and the mean elimination half-
life is 17.9 hours. Enterohepatic recirculation of MPA contributes to plasma 
concentrations. Administration of cholestyramine interrupts the enterohepatic 
recirculation and can decrease bioavailability by as much as 40%.  Patients 
with renal insufficiency have increased plasma concentrations of MPA and 
MPAG. Acyclovir and ganciclovir may compete with MPAG for renal 
tubular secretion, resulting in increased plasma concentrations of both drugs.

5.8  Tacrolimus (FK506, Prograf®, Protopic®) 
Source 
& 
Pharmacology  
Tacrolimus is a macrolide immunosuppressant produced by Streptomyce 
tsukubaensis. It inhibits T-lymphocyte activation, although the exact 
mechanism of action is not known. Tacrolimus activity is primarily due to 
the parent drug.  The plasma protein binding of tacrolimus is approximately 
99% and is independent of concentration over a range of 5-50 ng/mL.  The 
t½ in adult patients ranges from 11-19 hours.  Whole blood trough 
concentrations from 31 patients less than 12 years old showed that pediatric 
patients needed higher doses than adults to achieve similar tacrolimus trough 
concentrations.  It is extensively metabolized by the mixed-function oxidase 
system, primarily the cytochrome P-450 system (CYP3A) in the liver and to 
a lesser extent in the intestinal mucosa.  The main route of elimination is via 
the biliary tract and excretion in feces.  A retrospective comparison of Black 
and Caucasian kidney transplant patients indicated that Black patients 
required higher tacrolimus doses to attain similar trough concentrations; 
there were no gender-based differences.  The absorption of tacrolimus from 
the gastrointestinal tract is incomplete and variable exhibiting large intra- and 
inter-patient variability. Administration with food significantly decreases the 
rate and extent of absorption. Drugs that stimulate or inhibit hepatic p-450 
enzymes will alter clearance of tacrolimus and close attention to potential 
drug interactions is crucial. 
Formulation 
and Stability 
Intravenous formulation: Tacrolimus is available as a sterile solution 
(tacrolimus injection) containing the equivalent of 5 mg anhydrous 
tacrolimus in 1 mL Each mL contains polyoxyl 60 hydrogenated castor oil

5°C and 25°C (41°F and 77°F). Oral formulations: It is available for oral 
administration as capsules containing the equivalent of 0.5 mg, 1 mg or 5 mg 
of anhydrous tacrolimus. Inactive ingredients include lactose, hydroxypropyl 
methylcellulose, croscarmellose sodium, and magnesium stearate. The 0.5 
mg capsule shell contains gelatin, titanium dioxide and ferric oxide, the 1 mg 
capsule shell contains gelatin and titanium dioxide, and the 5 mg capsule 
shell contains gelatin, titanium dioxide and ferric oxide. Store at 25°C

Toxicities  
Immunosuppression results in increased susceptibility to infection and 
possible development of lymphoma and other malignancies, particularly of 
the skin.  After intravenous administration, monitor closely for an acute 
allergic reaction for the first 30 minutes and at frequent intervals thereafter.  
Fetal toxicity has been noted in animals.  Common adverse effects are 
headache, hypertension, GI toxicities, fever, immunosuppression, tremor, 
renal dysfunction, hematological abnormalities, CNS abnormalities,

electrolyte abnormalities, clotting abnormalities, alopecia.  Late effects can 
include skin disorders, delayed wound healing, and hirsutism.   Insulin-
dependent post-transplant diabetes mellitus (PTDM) was reported in 11-22% 
of tacrolimus treated transplant patients without pretransplant history of 
diabetes mellitus, several human studies. Mild to severe hyperkalemia is 
reported in 8-45% of transplant patients receiving tacrolimus, so serum 
potassium levels should be monitored and potassium-sparing diuretics should 
not be used. To avoid excess nephrotoxicity, tacrolimus should not be used 
simultaneously with cyclosporine or other drugs that may be associated with 
renal dysfunction.  Tacrolimus or cyclosporine should be discontinued at 
least 24 hours prior to initiating the other. In the presence of elevated 
tacrolimus or cyclosporine concentrations, dosing with the other drug usually 
should be further delayed.  It is not recommended that sirolimus and 
tacrolimus be given concomitantly, as serious increases in wound healing 
complications, renal function impairment and insulin-dependent post-
transplant diabetes mellitus have been observed.  Drugs that stimulate or 
inhibit p-450 enzymes will alter clearance of tacrolimus and close attention 
to potential drug interactions is crucial.

5.10 CliniMACSTM System   
The mechanism of action of the CliniMACS Cell Selection System is based on magnetic-
activated cell sorting (MACS).  The CliniMACS device is a powerful tool for the 
isolation of many cell types from heterogeneous cell mixtures, (e.g. apheresis 
products).  These can then be separated in a magnetic field using an immunomagnetic 
label specific for the cell type of interest, such as CD3+ human T cells. 
The cells to be isolated are specifically labeled with super-paramagnetic particles by an 
anti-body directed toward a cell surface antigen.  After magnetic labeling, the cells are 
separated using a high-gradient magnetic separation column as described below.  The 
magnetically labeled cells are retained in the magnetized column while the unlabeled 

HAPCORD 33 
 
Initial version, dated: 08/22/14 
 
IRB approval date: 10/17/14 
Protocol document date: 08/22/14 
 
cells flow through the column for collection.  The retained cells are eluted by removing 
the magnetic field from the column, washing the cells out and collecting them in a 
separate container from the unlabeled cells. 
The super-paramagnetic particles are small in size (about 50 nm in diameter) and are 
composed 
of 
iron 
oxide/hydroxide 
and 
dextran 
conjugated 
to 
monoclonal 
antibodies.  These magnetic particles form a stable colloidal solution and do not 
precipitate or aggregate in magnetic fields.  The antibody conjugated beads used in this 
system are highly specific (e.g. CD3+ cells via OKT3 conjugated beads). High-gradient 
MACS technology has been shown to achieve rapid and highly specific depletion or 
enrichments of large numbers of target cells from BM, cord blood, and normal peripheral 
blood mononuclear cells.  
The CliniMACS device incorporates a strong permanent magnet and a separation column 
with a ferromagnetic matrix to separate the cells labeled with the magnetic particles. The 
high-gradient system allows the application of strong magnetic forces and a rapid de-
magnetization. Small ferromagnetic structures, such as the column matrix, placed in a 
magnetic field concentrate this homogenous field and thereby produce high magnetic 
gradients. In their immediate proximity, the ferromagnetic structures generate magnetic 
forces 10,000-fold greater than in the absence of those structures enabling the retention of 
magnetically labeled cells. After removing the column from the magnet, the rapid de-
magnetization of the column matrix allows the release of retained cells.  
The CliniMACS device is comprised of a computer controlled instrument incorporating a 
strong permanent magnet, a closed-system sterile tubing set containing columns with a 
coated ferromagnetic matrix and a paramagnetic, cell specific, labeling reagent. The 
instrument will separate the cells in a fully automated process yielding a cell population 
highly depleted of CD3+ cells. The CliniMACS device is not licensed by the FDA and 
therefore is investigational. 
The CliniMACS device has separate programs that allow cell selection procedures 
optimized for either depletion (e.g. CD3+ or CD45RA+) or selection of a target cell 
population (e.g. CD34+ or CD56+ cells). The basic mechanism is the same for either 
application; target cells are "tagged" with super-paramagnetic particles and eventually 
separated from the unlabeled cells using the CliniMACS device as described above. The 
desired target cells can either be infused or discarded appropriately.

REQUIRED OBSERVATIONS AND EVALUATIONS 
6.1 Standard Pre/Peri/Post-Transplant Evaluations 
All pre/peri/posttransplant and long-term follow-up evaluations for these participants will 
be carried out as guided by the SOPs of the SJCRH, Department of BMTCT, for 
recipients of allogeneic HCT.  Copies of these SOPs and ongoing updates can be found at 
the following site: http://home.web.stjude.org/bone_marrow/clinicalHome.shtml.  A 
schedule of these for these assessments is outlined in Appendix D. 
6.2 Long-term Follow-up Evaluations 
In general, recipients of allogeneic HCT at St. Jude are seen at least annually until 10 
years post-transplant in the Department of BMTCT outpatient clinic. For the purpose of 
this study, research participants will be followed to year 1 post-transplantation. At that 

HAPCORD 34 
 
Initial version, dated: 08/22/14 
 
IRB approval date: 10/17/14 
Protocol document date: 08/22/14 
 
time, transplant recipients will be eligible for enrollment in the institutional long-term 
follow-up protocol for children and young adults who have received stem cell 
transplantation at St. Jude Children’s Research Hospital (BMTFU protocol). 
6.3 Research Testing.   
Timing for the required research tests are summarized in Appendix D.  Furthermore, to 
accommodate the studies, flexibility in the date is allowed without a deviation from 
protocol.  The degree of flexibility in the timing is also provided in Appendix D.  
6.3.1  Immune Reconstitution 
Standard measures of post-HCT immune reconstitution will be performed as 
delineated in Appendix D.  Research testing of Immune Reconstitution will 
include:  
6.3.1.1  VBETA/TREC Research: Thymic output and T cell repertoire. 
6.3.1.2  Lymphocyte Phenotypes Research: T cell and NK cell number and function. 
6.3.1.3  IR-PHENOTYPE 
Donor: Donor UCB cells necessary for research studies will be harvested 
from the discarded bag post infusion, ensuring that UCB cells will not be 
diverted from patient care. Immunophenotypic evaluation of the UCB unit 
prior to infusion will be performed to enumerate the content of naïve, 
memory T cells, regulatory T cells, NK cells, and naïve B cells and memory 
B cells.   
Host: Immunophenotypic evaluation of immune reconstitution in the patient 
will be performed for the enumeration of naïve, memory T cells, regulatory 
T cells and naïve B cells and memory B cells.  
6.3.1.4  T-FUNCTION 
Immune function studies include antigen-specific T-lymphocyte response to 
viral infections, such as herpes viruses (CMV, HSV and VZV), intracellular 
cytokine and cytokine secretion assays.  Studies may include an optional 
skin punch biopsy, at the discretion of the PI, to be performed either at the 
time of the pre-transplant BM biopsy, during sedation for radiation 
treatment or at the time of the day 28 BM biopsy.  During viral infections, or 
reactivations detected by DNA regardless of copy number, samples to be 
collected weekly x 4 or until cleared (whichever is less).  If infection(s) are 
detected in non-blood samples (nasal wash, BAL etc), leftover samples may 
be used for research purposes.  Studies to be performed in the laboratory of 
Dr. Paul Thomas in collaboration with Dr. Dallas.  
6.3.1.5  HOST-DONOR INTERACTION 
Donor: Donor UCB cells necessary for research studies will be harvested 
from the discarded bag post infusion, ensuring that UCB cells will not be 
diverted from patient care.  Epstein-Barr virus transformed lymphoblastoid 
cell lines (EBV-LCL) will be generated from the donor cells obtained from 
the discarded infusion bag.  UCB KIR typing and HLA-typing will be

performed for high resolution HLA-A, HLA-B, HLA-DR, HLA-C and 
HLA-DQ if not available.   
Host: Host and donor immunologic interaction studies may also include an 
optional skin punch biopsy to be performed with the pre-transplant BM 
biopsy to generate fibroblasts.  Prior to the start of conditioning, peripheral 
blood samples will be collected to generate EBV-LCL from the patient for 
research studies evaluating donor/host immunologic reactions. 
 
6.4 Research Testing on Haploidentical Donor (optional) 
Donors will be offered the option for participation in research studies of immune 
reconstitution of T cells, B cells, and NK cells.  These tests will be obtained after consent 
and preferably prior to growth factor administration.  Lymphocyte subset analysis of the 
donor appears to allow for the prediction of the reconstitution of the lymphocyte subsets 
in the research participant after transplantation.  Data in larger donor/research participant 
pairs will help to verify these observations. A list of these optional research studies are 
noted in Appendix D and detailed below: 
6.4.1  Lymphocyte Subset Study: Flow cytometry enumeration 
6.4.2  VBETA/TREC Research: Thymic output and T cell repertoire 
6.4.3  Lymphocyte Phenotypes Research: T cell and NK cell number and function 
7.0 EVALUATION CRITERIA 
7.1  Adverse event (AE) monitoring for on-study research participants will be assessed using the 
NCI Common Toxicity Criteria Version 3.0.  The specific criteria for adverse event 
monitoring are noted in APPENDIX C. 
7.2 GVHD scoring (acute and chronic) will be evaluated and graded using the criteria found 
in APPENDIX B of this protocol. 
7.3 Performance status will be assessed by Karnofsky/Lansky Performance Scores (age-
dependent) (see APPENDIX A). 
7.4 Hematologic recovery post-transplant will be determined using the engraftment criteria as 
follows:  
(1) Neutrophil engraftment is defined as absolute neutrophil count (ANC) recovery of ≥ 
0.5 x 109/L (500/mm3) for three consecutive laboratory values obtained on different 
days. Date of engraftment is the date of the first of the three consecutive laboratory 
values. 
(2) Platelet engraftment will be defined as platelet count ≥ 20,000/mm3 for three consecutive 
laboratory values obtained on different days with no platelet transfusions in the 
preceding 7 days.  Date of engraftment is the date of the first of the three consecutive 
laboratory values. 
7.5 Primary graft failure will be defined as an ANC never meeting or exceeding 500/mm3 for 
3 consecutive measurements after day +42 post-transplant.

9.0 SAFETY AND ADVERSE EVENT REPORTING REQUIREMENTS 
9.1 Reporting adverse experiences and deaths 
The following definitions apply: 
Serious event – any event, in which the outcome is fatal or life-threatening, results in 
permanent disability, causes inpatient hospitalization or prolongs existing hospitalization, 
or is a congenital anomaly, cancer, or overdose. 
Unanticipated adverse event – any event, not identified in their nature, severity, or 
frequency in the current risk documents (e.g., investigator’s brochure), or consistent with 
the investigational plan. 
9.2 Reporting to St. Jude Institutional Review Board (IRB) 
Principal investigators are responsible for promptly reporting to the IRB any adverse 
events that are unanticipated, serious, and that may represent potential harm or increased 
risk to research participants.  When an unanticipated death occurs, the PI should report it 
to the Director of Human Subject’s Protection immediately, by phone: (901) 595-4359, 
cell: (901) 336-2894, fax: (901) 595-4361, or e-mail: hsp-1@stjude.org.  A reportable 
event entry into TRACKS should follow within 48 hours of notification of the event. 
Serious, unanticipated, and related or possibly related events must be reported within 10 
working days of notification of the event.  At the same time, the investigator will notify 
the study sponsor and/or the FDA, as appropriate.  All other SAEs and captured AEs will 
be reported to the IRB in the continuing review, with the following exceptions: 
 Any grade III-IV infusion reactions will be reported as soon as possible but every 
effort should be made to assure reporting is no more than within 7 business days 
of the event. 
 Any episodes of overall grade III or IV acute GVHD in participants will be 
reported to the IRB as soon as possible but no more than within approximately 10 
days of the PI’s confirmation of the diagnosis/grade of the event. 
 Clinical diagnosis of PTLPD will be reported to the IRB as soon as possible but 
no more than within 10 days of the PI’s determination of the disorder. 
The principal investigator is responsible for reviewing the aggregate toxicity reports and 
reporting to the IRB if the frequency or severity of serious toxicities exceed those 
expected as defined in the protocol or based on clinical experience or the published 
literature.  Any proposed changes in the consent form or research procedures resulting 
from the report are to be prepared by the study team and submitted with the report to the 
IRB for approval. 
Recipient participants will be followed for NCI Grade III-V, and clinically significant I-
II, adverse events from the start of conditioning and throughout the first year post HCT, 
regardless of their relationship to the treatment given.  However, all GVHD events will 
be captured on an ongoing basis regardless of stage or grade.

Haploidentical donor participants will be followed for any serious AE (SAE) and any 
clinically significant AEs (per judgment of PI) that are deemed related to the mobilization 
and/or apheresis procedure from the time of initiation of mobilization growth factors to 7-
days post last day of the apheresis procedure.  If the transplant recipient requires a second 
HSC infusion, meaning that the donor is required to undergo the mobilization and 
apheresis procedure again, collection of this donor safety data will restart upon the 
initiation of the subsequent mobilization procedure and continue until 7-days post the last 
day of this apheresis procedure. Timelines for reporting of these donor events to the 
institutional and federal governing agencies will be according to the same timelines noted 
in the following sections. A listing of the captured donor safety data will be provided in a 
separate table from the transplant recipients within each respective continuing review 
report.  Continuing review reports to all regulatory authorities will be structured in a 
manner so that any infusion toxicities or stem cell product related variances will be 
reported in separate listings from all other required elements. 
9.3 Reporting to St. Jude Institutional Biosafety Committee (IBC) 
Continuing review reports will be sent to the IBC on at least an annual basis using the 
most current version of the continuing review form found on the IBC website. The safety 
reports, sent to the IRB for both the donors and stem cell recipients, will be 
simultaneously forwarded to the IBC. Therefore, reporting for safety events to this 
committee will be according to the same timelines as reporting to the IRB.  This includes 
notification of achievement of MTD (if/when applicable).  As per the direction of the 
IBC, only those protocol revisions and amendments directly related to the CliniMACS 
processing and related reagent(s) will require review and consideration by the IBC.  
Other revisions/amendments will be noted in the IBC continuing review report. 
9.4 Reporting to FDA  
The FDA will be notified in writing (IDE safety report) of any serious and unexpected 
AE associated with an investigational treatment or device; or any results from laboratory 
animal tests that suggest a significant risk for human subjects including reports of 
mutagenicity, teratogenicity, or carcinogenicity. 
Each notification to the FDA should be made as soon as possible and no later than 15 
calendar days after the sponsor’s initial receipt of the information. The FDA may 
require additional data to be submitted.  In each written IND safety report, the sponsor 
shall identify all safety reports previously filed with the IND concerning a similar adverse 
experience, and shall analyze the significance of the adverse experience in light of the 
previous, similar reports where applicable. 
The sponsor shall also notify the FDA by telephone or by facsimile transmission of any 
unexpected fatal or life-threatening experience associated with the use of the 
investigational medication as soon as possible but no later than 7 calendar days after the 
sponsor’s initial receipt of the information.  Any grade III-IV infusion reactions will be 
reported as soon as possible but every effort should be made to assure reporting is no 
more than within 7 business days of the event.  Follow-up information to a safety 
report must be submitted as soon as the relevant information is available.

If the results of further investigation show an AE that was not initially determined to be 
reportable should later be deemed reportable, the sponsor shall inform the FDA of the 
event in a written safety report as soon as possible, but no later than 15 calendar days 
after the determination is made.  Results of the investigation of other safety information 
shall be submitted, as appropriate, in an information amendment or annual report.  
Continuing review reports, which will include the up-to-date clinical and safety data, will 
be submitted to the FDA at least annually. 
9.5 Reporting to St. Jude Office of Regulatory Affairs 
Copies of all correspondence to the St. Jude IRB, including SAE reports are provided to 
the St. Jude Regulatory Affairs Office. All FDA related correspondence and reporting 
will be conducted through the Regulatory Affairs Office. Adverse event reporting and 
annual reporting will be in accord with the FDA Title 21 CFR312.32 and Title 21 
CFR312.33, respectively. The Regulatory Affairs Office can be reached at 901-595-2347 
(secondary contact: St. Jude Vice President of Clinical Trials Administration 901-595-

9.6 Continuing review reports 
Continuing review reports of protocol progress and summaries of adverse events will be 
filed with the St. Jude IRB, and IBC at least annually. 
9.7 Reporting to the St. Jude Data Safety Monitoring Board 
This study has been referred to the St. Jude Data and Safety Monitoring Board (DSMB) 
for regular monitoring.  The DSMB is charged with advising the Director and other 
senior leaders of St. Jude on the safety of clinical protocols being conducted by St. Jude 
investigators and on their continuing scientific validity.  DSMB monitoring and review 
for this study will be conducted in accordance with the NCI guidance for DSMBs on an 
approximate semiannual basis.  The St. Jude DSMB is responsible for ongoing review of 
the protocol and related information such as enrollment, issues related to participant 
safety (specifically toxicities and the risk:benefit ratio of the trial), interim analyses, and 
the overall study conduct necessary to accomplish the primary protocol objectives.  This 
includes evaluation of the accrual rate, adherence to the study design, outcome measures, 
and review of protocol related primary outcome data. The PI will meet with DSMB 
during the semiannual visits to review the information submitted and discuss the status of 
the protocol.  The DSMB may recommend that the trial be modified, suspended to 
accrual, and/or stopped based on their review.

of autologous and all allogeneic (related and unrelated donor) transplants performed in 
the United States. 
The Office of General Counsel, U.S. Department of Health and Human Services, had 
deemed the CIBMTR not a covered entity under the Privacy Rule (45 CFR 164.512), 45 
CFR Parts 160 and 164, and the Health Insurance Portability and Accountability Act 
(HIPPA) of 1996.  For this reason, the submission and disclosure of certain protected 
health information (PHI), including that required for CIBMTR, is allowable without the 
individual’s authorization (i.e. consent is waived) when such disclosure is made to public 
health authorities authorized by law for the purpose of preventing or controlling disease, 
injury, or disability. 
Data resulting from this transplant procedure will be sent for general registry purposes to 
comply with the federal government requirements.  This information for both donor and 
recipient is submitted using a unique participant identification number.  The information 
submitted for haploidentical recipients is less extensive than recipients of other donor 
products.  For this reason, variables submitted may include but are not limited to the 
transplant recipient’s date of birth, country/state of current residence, diagnosis, basic 
lympho-hematopoietic reconstitution (e.g. date of ANC and platelet engraftment), post-
HCT disease status, and basic AEs (e.g. GVHD- yes or no), survival status, date/cause of 
death. 
10.0 DATA COLLECTION, STUDY MONITORING, AND CONFIDENTIALITY 
10.1  Data collection 
The St. Jude Cancer Center Clinical Research Associates assigned to the Department of 
BMTCT will assure protocol compliance, and conduct all clinical and safety data 
collection. Data will be entered into an institutional database. The PI will be responsible 
for review of data for accuracy and completeness once entered into the secure 
departmental database. 
10.2  Study monitoring 
This protocol will be monitored for safety and data as per the St. Jude Data and Safety 
Monitoring Plan for Clinical Trials approved by the NCI in 2010, and is considered to be 
in the High Risk III category. The Central Protocol and Data Monitoring Office 
(CPDMO) will verify 100% of the informed consent documentation on all participants 
and verify 100% of St. Jude participants’ eligibility status.  The study team will meet at 
appropriate intervals to review case histories and data quality summaries on all 

HAPCORD 41 
 
Initial version, dated: 08/22/14 
 
IRB approval date: 10/17/14 
Protocol document date: 08/22/14 
 
participants.  The St. Jude Clinical Research Monitor will assess protocol and regulatory 
compliance as well as the accuracy and completeness of all data points for the first two 
participants enrolled, then 15% of study enrollees every six months.  The protocol will be 
tracked continuously for the accrual of donors and recipients.  All AE and SAE reports 
will be reviewed by the study Principal Investigator for type, grade, attribution, duration, 
timeliness and appropriateness on all study participants.  All SAE reports will be 
reviewed by the monitor every 6 months.    
Protocol compliance monitoring will include participant status, eligibility, the informed 
consent process, demographics, staging, study objectives, subgroup assignment, 
treatments, evaluations, responses, participant protocol status, off-study, and off-therapy 
criteria.  The Monitor will generate a formal report which is shared with the Principal 
Investigator (PI), study team and the Internal Monitoring Committee (IMC).  Monitoring 
may be conducted more frequently if deemed necessary by the CPDMO or the 
IMC.  Continuing reviews by the IRB and CT-SRC will occur at least annually.  In 
addition, SAE reports in TRACKS (Total Research and Knowledge System) are reviewed 
in a timely manner by the IRB.  The Regulatory Affairs Office will assist the PI in 
reporting to the FDA and other external oversight agencies, as necessary. 
10.3 Confidentiality 
Unique participant numbers will be used in place of an identifier such as a medical record 
number when reporting any data to outside agencies.  No research participant names will 
be recorded on the data collection forms.  The list containing the unique participant 
numbers and the medical record number will be maintained in a locked file accessible 
only to the study team. 
The medical records of study participants may be reviewed by the St. Jude IRB, FDA, 
clinical research monitors, etc. 
11.0 STATISTICAL CONSIDERATIONS 
11.1 Statistical design and analysis for the primary objectives and stopping rules 
This study is designed as a phase II study. The primary objective of this study is to 
evaluate the rate of engraftment by day +42.  Engraftment for the purposes of this 
objective will be as defined in section 7. 
As detailed in section 2, the use of alternative donors such as haploidentical donors and 
unrelated UCB are frequently needed and largely successful.  However, the use of these 
alternative donors is typically complicated with additional problems, particularly poor 
hematopoietic recovery and graft failure.126    
The majority of published experience with alternative (HLA-mismatched) donor 
transplantation in children is with UCB grafts.  The COBALT study included 191 
children with hematologic malignancies who received UCB transplantation with TBI 
based (1350Gy) myeloablative conditioning.59 The cumulative incidence of neutrophil 
engraftment by day 42 was 80%.  The New York Blood Center published outcomes on 
1061 patients (78% pediatric) with hematologic malignancies who received 
myeloablative UCBT with units from their bank.62 The cumulative incidence of 
neutrophil engraftment was 74% by day 77.  The CIBMTR published a comparison of 
UCB transplantation with HLA-matched unrelated donor transplantation, in which 503 

HAPCORD 42 
 
Initial version, dated: 08/22/14

Protocol document date: 08/22/14 
 
children with acute leukemia received UCBT.16 They confirmed that although the 
leukemia-free survival was similar, the rate of neutrophil engraftment (and TRM) were 
significantly worse with HLA-mismatched UCB grafts than with HLA-matched BM 
grafts.  For UCB recipients, the best engraftment was obtained in the rare 6/6 matched 
UCB recipients with 85% of the 35 patients achieving neutrophil recovery at day +42.  In 
addition, recipients who received a single antigen mismatch UCB unit with an 
appropriately high cell dose (n=154) had a neutrophil engraftment rate of 80% at day 
+42.  Recipients of lower cell dose or two antigen mismatch units fared worse. 
Given the data, we consider a rate of successful engraftment of less than 80% by day +42 
to be unacceptable for alternative donor transplantation.  The goal of our study is to 
develop a novel preparative regimen to facilitate successful engraftment of donor graft(s) 
at a rate of ≥91%.  We do not anticipate censoring during the 42 day time period and we 
can approximate the rate of engraftment by day +42 using a Binomial distribution. In 
order to keep the validity of Binomial distribution approximation, patients lost for follow 
up will be counted as a failure to engraft. Therefore, in this study, we propose to test the 
null hypothesis H0: P≤0.80 versus H1: P>0.80, where P is the proportion of research 
participants who engrafted by day +42 after HCT. With type I error of 10% and type II 
error of 20%, Simon’s two stage optimum design powered at alternative successful 
engraftment rate P1=0.91 requires 21 evaluable patients at the first stage and 49 evaluable 
patients in total76. The stopping rules are provided in Table 1, with the understanding that 
stopping the trial early would be suggestive of the proposed transplant strategy not being 
an effective treatment option for this group of patients. The interpretation is that if we 
observe 17 or fewer participants engrafted by day +42 in the first 21 participants, then we 
would stop the trial for lack of efficacy. However, if we observe 18 or more patients 
engrafted in the first 21 participants by day +42 in stage one, then 28 more patients will 
be enrolled in stage two. If we observe 43 or more participants engrafted by day +42 
upon completion of the trial, then we conclude that the true rate of  engraftment is at least 
80% and our novel regimen will be proposed for further development and phase III 
clinical trial.

Note: r1 and r denote the number of patients successfully engrafted by day +42; EN(P0) 
denotes the expected sample size under P0; PET(P0) denotes the probability of early 
termination at stage I under P0.  
All participants who receive the prescribed transplant will be evaluable for the primary 
outcome. In addition, any patient who starts the conditioning regimen but stops prior to 
receiving the graft will count as a failure, if the reason for stopping therapy is toxicity 
from the conditioning regimen.  Patients who enroll but do not initiate treatment due to 
withdraw of patient, withdraw of donor or health status change to make the treatment not 
in the patient’s best medical interest, etc., will be replaced.  Any patient who dies from

toxicity after engraftment but before day +42 will count as having engrafted.  Any patient 
who dies prior to engraftment will count as a graft failure.   
After the study is finished, for the first primary objective, the rate of engraftment by day 
+42 and its 95% Blyth-Still-Casella confidence interval will be estimated based on the 
binomial approximation.  
Table 2 shows the number of haploidentical HCT and the estimated number of KIR 
mismatch cases performed at our institution in last 5 years. With the initiation of UCB 
protocols at SJCRH, the number of referrals for patients requiring alternative donor HCT 
has increased.  Furthermore, HAPCORD will be a high priority protocol. Based on this 
table and PI’s estimation, it is expected that approximately 10 patients per year will be 
enrolled in this study.  Therefore, the expected accrual period for this study is maximally 
5 years.

Stopping Rules for Toxicities  
In addition to the stopping rules based on successful engraftment, we will closely monitor 
the trial for early excessive toxicities in terms of severe acute GVHD and therapy related 
death. Therapy related death is any death in remission and related to protocol therapy.  
The incidence of acute GVHD and transplant related deaths will be monitored for 100 
days from the date of transplantation for application of the stopping rules. Toxicities 
secondary to non-protocol therapy for post-transplant persistent or recurrent disease will 
not count towards the toxicity stopping rules. The safety endpoints will be monitored 
independently and a consideration to stopping the trial would be given if there is evidence 
suggesting that the rate of grades 3-4 acute GVHD is greater than 20%, or the rate of 
transplant related death is greater than 10%. Then, the planned interim evaluation time 
points and stopping rules, using group sequential design based on Pocock stopping 
boundaries after considering five interim analyses (p-value threshold = 0.0158) to ensure 
an overall type one error of 0.05127-129, for each of the two endpoints are provided in

Based on the above Table 3, if six grades 3-4 acute GVHD occur within the first 100 days 
post transplantation in the first eleven evaluable research participants treated, then a 
consideration will be given to temporarily stopping the trial and amending the study to 
include additional pharmacologic GVHD prophylaxis. Similarly, from Table 4 if we 
observe five deaths related to therapy within the first 100 days after transplantation in the 
first eleven evaluable research participants treated, then a consideration will be given to 
temporarily stopping the trial and amending the study appropriately.    
11.2 Statistical analysis for secondary objectives  
11.2.1  Estimate the incidence of malignant relapse, EFS and OS at one-year post-
transplantation 
The estimate of cumulative incidence of relapse will be estimated using 
Kalbfleisch-Prentice method. Death is the competing risk event. The analysis will 
be implemented using SAS macro (bmacro252-Excel2007\cin) available in the St. 
Jude Department of Biostatistics. The Kaplan-Meier estimate of OS and EFS with 
relapse, death due to any cause and graft failure as events along with their 
standard errors will be calculated using the SAS macro (bmacro251-
Excel2007\kme) available in the Department of Biostatistics at St. Jude, where 
OS = min (date of last follow-up, date of death) – date of HCT and all participants 
surviving after 1 year post-transplant will be considered as censored, and EFS = 
min (date of last follow-up, date of relapse, date of graft failure, date of death due 
to any cause) – date of transplant, and all participants surviving at the time of 
analysis without events will be censored. The analysis for this objective will be 
performed when the last evaluable participant has been followed for one-year post 
transplant.    
11.2.2  Estimate the incidence and severity of acute and chronic GVHD 
The cumulative incidence of acute and chronic GVHD will be estimated using 
Kalbfleisch-Prentice method. Death is the competing risk event. The SAS macro 
(bmacro252-Excel2007\cin) available in the Department of Biostatistics at St. 
Jude will be used for such analysis. The severity of acute GVHD and chronic 
GVHD will be described. The analysis for this objective will be performed when 
the last evaluable participant has been followed for 100 days post transplant.   
11.2.3 Estimate the rate of TRM in the first 100 days after HCT. 
The cumulative incidence of TRM will be estimated using the same method as 
used in evaluating Objective 10.2.2. Deaths before day 100 because of other 
reasons are the competing risk events. The analysis for this objective will be 

HAPCORD 45 
 
Initial version, dated: 08/22/14 
 
IRB approval date: 10/17/14 
Protocol document date: 08/22/14 
 
performed when the last evaluable participant has been followed for 100 days post 
transplant. 
11.3 Analysis for exploratory objectives  
The final results of these exploratory objectives are expected to be available when 
the last evaluable participant has been followed for one-year post transplant. 
11.3.1  Assess the relationship between pre-transplant MRD with transplant outcomes. 
The relationship of pre-transplant MRD and transplant outcomes will be 
examined through Cox proportional hazard model or generalized linear model. 
The model can also be used to adjust for other confounding factors such as 
patient’s age at transplant. 
11.3.2 Record immune reconstitution parameters, including chimerism analysis, 
quantitative lymphocyte subsets, T cell receptor excision circle (TREC) analysis, 
V-beta spectratyping, and phenotype and functional analysis of reconstituted 
lymphocyte subsets.  All immune reconstitution measures will be descriptively 
analyzed. 
11.3.3 Characterize the recovery of Gamma Delta T cells after HCT, including T cell 
receptor analysis, phenotyping and functional analysis.  All Gamma Delta T cell 
measures will be descriptively analyzed. 
11.3.4 Characterize influenza infection during HCT by monitoring viral isolates and key 
host factors associated with influenza susceptibility.  All Influenza infection 
monitoring will be descriptively analyzed. 
12.0 OBTAINING INFORMED CONSENT 
The ongoing informed consent process will be carried out per the policies and procedures put 
forth in the St. Jude Investigator’s Handbook for Clinical Research (http://home.web.stjude. 
org/clinical_research/administration/doc/handbook.pdf).  The PI or physician sub-
investigator will conduct the signature authorization portion of the consent process.   
12.1 Informed consent prior to research interventions 
For protocol required research interventions (research samples for baseline immune 
reconstitution evaluation); informed consent must be obtained prior to performing these 
research interventions. 
12.2 Consent at age of majority 
The age of majority in the state of Tennessee is 18 years old.  Research participants must 
be consented at the next St. Jude clinic visit after their 18th birthday, and prior to 
performing any research interventions during that visit.   
12.3 Consent when English is not the primary language 
When English is not the patient, parent, or legally authorized representative’s primary 
language, the Social Work department will determine the need for an interpreter.  This 
information will be documented in the participant’s medical record.  Either a certified 
interpreter or the telephone interpreter’s service will be used to translate the consent 
information.  The process for obtaining an interpreter and for the use of an interpreter is 
outlined on the Interpreter Services, OHSP, and CPDMO websites.

 Organ scoring of chronic GVHD. 
AP may be elevated in growing children, and not reflective of liver dysfunction.    
† Pulmonary scoring should be performed using both the symptom and PFT scale whenever possible. When discrepancy exists 
between pulmonary symptoms or PFT scores, the higher value should be used for final scoring. Scoring using the  LFS  is 
preferred, but if DLCO is not available, grading using FEV1 should be used.  The LFS is a global assessment of lung function 
after the diagnosis of bronchiolitis obliterans has already been established.   
The percent predicted FEV1 and DLCO (adjusted for HCT but not alveolar volume) should be converted to a numeric score as 
follows: >80% = 1; 70-79% = 2; 60-69% = 3; 50-59% = 4; 40-49% = 5; <40% = 6.   
The LFS = FEV1 score + DLCO score, with a possible range of 2-12.

 
The information derived from or noted on the physical examinations, standard tests, and other assessments that comprise standard of care for recipients are not required to 
be transcribed onto case report forms and/or entered into the database.  In reference to section 6.1 Evaluations, the above-indicated follow-up regimen for these evaluations 
is guided by the SOPs of the Department of BMTCT, for recipients of allogeneic stem cell transplantation.  As these evaluations are considered standard clinical care (non-
research), variations in frequency (more or less frequent) of these evaluations can occur due to the participant’s current clinical condition and will not be noted as protocol 
deviations. 
 
Disease status evaluations/BM testing results obtained prior to enrollment may be used for the baseline/pre-infusion assessments. 
 
 MRD PB required for T-Cell ALL only 
 
Lymphocyte subset studies may be omitted without variance when the absolute lymphocyte count (ALC) is zero. 
 
In the event of graft failure/rejection, the post failure/rejection time period BM, chimerism and several of the applicable immune studies will be held, as these 
blood/marrow tests would not be clinically indicated.
