Brief summary:
Approximately 30% of patients who are candidates for bone marrow transplants do not have an HLA-matched, or close to matched, donor available. For this reason, doctors have been testing ways to make transplants from HLA-partially matched donors as safe and effective as transplants from HLA-matched donors.

This study is being done to test the safety and the treatment results of a specific kind of transplant. In this transplant, blood from two donors will be used. Each donor will share one half of your HLA type. Blood from both donors will be transplanted at the same time.

PROTOCOL SUMMARY AND/OR SCHEMA 
 
1. Study Objectives: To evaluate biparental HLA-haploidentical T-cell depleted CD34+ 
peripheral blood stem cell (PBSC) transplants when applied to the treatment of patients with 
hematologic malignancies or lethal disorders of hematopoiesis who lack an HLA compatible 
related or unrelated donor.  Primary endpoints will include: 1) incidence, tempo and 
completeness of engraftment and hematopoietic reconstitution; 2) incidence of graft failure 3) 
incidence of acute and/or chronic GvHD; 4) incidence and severity of opportunistic infections; 
5)incidence of Transplant-related mortality, overall survival and disease-free survival. 
Secondary, endpoints will include: 1) levels of initial and sustained engraftment of 
hematopoietic cells and their lineage-specific progenitors from each parental donor; 2) the 
tolerance or allo responsiveness of T-cells generated in vivo from each parental donor 
against cells of the host or other parent and 3) the capacity of engrafted T-cells from each 
donor to respond to viral antigens presented by HLA alleles shared by the recipient and each 
donor or by HLA alleles unique to each donor. 
 
2. Design: Single center pilot study to provide initial data on the safety and efficacy of a 
biparental HLA haplotype disparate T-cell depleted transplant for patients lacking an HLA- 
compatible donor. 
 
3. Patient Inclusion Criteria: Patients diagnosed with histologically, proven high risk forms 
of acute or chronic leukemia, non-Hodgkins, myelodysplastic syndrome or other rare lethal 
disorders of hematopoiesis and lymphopoiesis for which a T-cell depleted transplant is 
indicated (e.g. hemophagocytic lymphohistiocytosis, refractory aplastic anemia or congenital 
cytopenias, non-SCID lethal immune deficiencies such as Wiskott-Aldrich Syndrome, CD40 
ligand deficiencies, ALPS). To be eligible, patients must lack an available HLA identical or 
9/10 HLA allele matched related or unrelated donor. The patient must have two consenting 
related donors of whom one shares with the patient the same paternal HLA A, B, C, DR, DQ 
haplotype and the other shares the same maternal HLA A, B, C, DR, DQ haplotype, who are 
willing and able to donate GCSF-mobilized PBSC. The patient must also meet the following 
clinical criteria: creatinine ≤ 1.2 mg/dl or if not, CrCl> 40ml/min/1.73m2, and total bilirubin < 
2xnl, ALT < 3xnl, adequate cardiac function i.e., LVEF > 50%, adequate pulmonary function- 
asymptomatic or if not, DLCO > % 50% (corrected for Hgb); Karnofsky performance status > 
70%; negative pregnancy test (where applicable); signed informed consent of patient and 
donor. 
 
4. Patient Exclusion Criteria: Pregnancy or lactation, unwillingness to comply with protocol 
treatment or follow-up uncontrolled infection, HIV or HTLV seropositivity, active leukemia in 
CNS. 
 
5. Pretreatment Testing: The following tests will be performed within approximately 30 days 
before beginning treatment: complete history and physical examination, dental evaluation 
(may be performed outside of approx 30 day window), HLA typing as per institutional 
guidelines, complete blood count (CBC), PT/PTT/INR, RBC type and screen and RFLP (may 
also be out of 30 day window) on the two donors and patient, comprehensive panel 
(including BUN, creatinine, electrolytes, glucose, total protein, albumin, liver function tests - 
AST, ALT, bilirubin, alkaline phosphatase), urinalysis, serum or urinary HCG in women of

months post transplant, and thereafter as clinically indicated. Chimerism will be assessed by 
Amended:  07/30/15 
Page 5 of 47 
 
 
month or sooner if there is indication that the disease is changing. In addition, chest X-ray 
and other types of scans (CT scan and PET scan, if needed), electrocardiogram, 
echocardiogram or a gated pool scan if needed, and pulmonary function test for patients 
older than 7 years, if indicated. Cytogenetic and molecular evaluations will be performed as 
clinically indicated. Microbial testing will be obtained as per the Blood Bank standards and 
BMT Service Guidelines. 
 
All patients with ALL or with M4 or M5 type AML must have a diagnostic LP performed within 
1 month prior to enrolling in this study. If there are signs or symptoms of CNS disease, or the 
hematologist/ oncologist feels it is indicated, an LP will be performed to exclude the presence 
of CNS disease prior to beginning therapy. Donors will undergo standard screening for PBSC 
donation. Whenever possible, samples of the patient’s hematologic disease will be obtained 
and prepared for cryopreservation for later in vitro studies. 
 
6. Summary of Treatment Plan: There are two myeloablative preparative regimens that can 
be used for transplants in this protocol. 
 
Regimen 1 consists of hyperfractionated TBI – 1375 cGy (or 1500 cGy for children with ALL 
> 1 CR) administered in 11 or 12 doses of 125 cGy each over a total of four days, with three 
doses on three days and two doses on the last day, fludarabine 25 mg/m2 IV x 5 days, and 
thiotepa 5mg/kg IV x 2 days (or 10mg/kg x 1 day). 
 
Regimen 2, to be given to patients non-malignant, life-threatening diseases and patients with 
hematologic malignancies, with extensive prior therapy and comorbidities who are unable to 
receive TBI, consists of Melphalan 70mg/m2 IV x 2 days, thiotepa 5mg/kg IV x 2 days (or 
10mg/kg x 1 day), and fludarabine 25 mg/m2 IV x 5 days. 
 
 
Recipients of these biparental HLA haplotype matched related stem cell transplants will 
receive ATG for three days prior to the transplant as per the BMT Service guidelines. G-CSF 
mobilized CD34 PBSCs obtained from each HLA- haplotype matched donor will be infused 
on day 0. Post transplantation G-CSF will be administered only if clinically indicated and 
should begin on or after d+7. Supportive care will be administered as per the BMT Service 
guidelines. 
 
Patients will be clinically evaluated daily as inpatients and at each clinic visit for incidence and 
severity of acute and chronic GVHD and transplant associated morbidity. Sequential 
evaluation of engraftment and functional reconstitution of hematopoiesis and immunity will be 
made as per the BMT Service guidelines. 
 
7. Approximate Evaluation during Treatment: CBCs may be obtained daily and 
chemistries will be obtained at least two times per week until d+30 or until discharge from the 
hospital, whenever possible. Thereafter, they are performed as clinically indicated. 
Assessment of disease will be made by bone marrow aspiration (when appropriate), and 
appropriate cytogenetic and molecular studies. Chimerism will be molecularly assessed to 
measure the proportion of cell populations derived from each donor and the host. These 
studies will be performed at approximately 30-100 days post transplant, 6, 12, and 24

RFLP analysis. Immune competence will be evaluated by peripheral blood lymphocyte (PBL) 
phenotyping at approximately 1, 3, 6, 9 months, and q3-6 months thereafter until normal. In 
vitro response of PBL to a standard panel of mitogens and antigens will be performed at 
approximately 3 and 6 months and then q3-6 months until normal. HLA- restricted T-cell 
responses to CMV and/or EBV as well as Mixed Leukocyte responses to irradiated PBMCs 
from the host, each donor and third party allogeneic cells will also be assessed at 3 and 6 
months and then q3-6 months until normal. 
 
8. Estimated number of study subjects: 21 patients 
 
9. Selection and evaluation of related donors for transplantation: Any pair of HLA A, B, 
C, DR, DQ haplotype- matched healthy family members in which one donor inherits the 
paternal HLA haplotype and the other inherits the maternal HLA haplotype shared by the 
patient will be considered for PBSC donation. Selection of the donors will be based on 
genotype matching of HLA-A, B, C, DR, DQ haplotype, to be carried out on the recipient, 
parents, siblings, or possibly other family members such as aunts, uncles, or first cousins. 
Each prospective donor must be matched for one or the other HLA haplotype (HLA-A, B, C, 
DR, DQ) of the patient. Each donor must also provide signed informed consent, to receive a 
5-6-day course of G-CSF and to undergo two leukaphereses. In addition, if the PBSC 
collection is inadequate the donor must consent to undergo a bone marrow harvest under 
general anesthesia. The donor will undergo a medical evaluation as per the BMT Service 
Guidelines for a related donor.

BACKGROUND AND RATIONALE 
 
Allogeneic hematopoietic stem cell transplants (HSCT) derived from HLA-matched related 
donors are now recognized as a potentially curative treatment of choice for patients afflicted 
with acute leukemia relapsing after initial remission, high risk forms of ALL and AML in 1° CR 
and MDS and advanced stages of NHL.[1-4] Furthermore, as a result of the improvements in 
the precision of HLA typing provided by DNA typing and the efficiency of donor identification 
and recruitment from the NMDP and its integrated network of donor registries in other 
countries, the results of transplants from matched unrelated donors for these diseases have 
also markedly improved [5-8], encouraging the application of such transplants in earlier, 
more responsive stages of disease. However, despite the fact that the NMDP and other 
cooperating donor registries have accrued over 13 million HLA typed donors willing to 
provide hematopoietic progenitor cell transplants (HSCT), normal HLA-matched or single 
HLA allele disparate donors can only be identified for 70% of the patients for whom a 
transplant is indicated.[9] 
 
To extend the application of HSCT to patients lacking an HLA compatible donor, two major 
strategies have been explored: 1) transplants of partially matched allogeneic umbilical cord 
blood cells, and; 2) transplants of HLA-haplotype matched T-cell depleted marrow or 
peripheral blood stem cells. 
 
Applications of single unrelated allogeneic cord blood transplants (UCBT) in the treatment of 
children with leukemia and genetic disorders of hematopoiesis have demonstrated the 
capacity of such transplants to achieve consistent durable engraftment and to reconstitute 
hematopoiesis and immunity.[10] Indeed, in children, the results of matched or 1 
antigen/disparate UCBT are comparable to those achieved with matched unrelated 
grafts.[11] Published reports also suggest that the incidence and severity of acute and 
chronic GVHD are less following UCBT than adult marrow or PBSC transplants. Indeed, the 
severity of GVHD observed following 2 HLA allele disparate UCBT is approximately that 
seen in recipients of 1 HLA allele disparate marrow grafts.[12] However, the incidence of 
graft rejection and the incidence of acute and chronic GVHD increases with greater HLA 
disparate and may be prohibitive when more than 2/6 HLA serologically typed antigens differ 
between donor and host.[13] Initial results of UCBT in adults with leukemia or aplastic 
anemia were markedly inferior to those achieved in children, in large part because single 
UCBT were associated with an unacceptably high incidence of graft rejection or failure.[14, 
15] Furthermore, despite the increase in the cumulative number of cord bloods now available

conditioning regimens that have reduced the incidence of graft failure following such T cell

for transplantation, there remains a sizable proportion of individuals for whom a sufficiently 
partially HLA matched UCB donor cannot be identified. 
 
However, as shown by Barker et al [16] consistent engraftment can be achieved in adults 
when two comparably matched UCBT units from different donors are administered. The 
strikingly consistent and more rapid engraftment and reconstitution suggests that the two 
allogeneic CBTs are mutually costimulatory. However, for as yet unclear reasons, when 
double cord grafts are administered, only one of the transplants durably engrafts and 
survives to reconstitute hematopoiesis.[17] As in the pediatric recipients of single UCBTs, the 
incidence and severity of acute and chronic GVHD are lower than in recipients of comparably 
matched unrelated marrow or PBSC transplants. However, HLA disparaties exceeding 2/6 
serologically defined HLA antigens are associated with a significantly higher incidence of 
severe acute and chronic GVHD and associated transplant-related mortality.[18] 
 
In order to extend the application of allogeneic HSCT to all patients for whom it is an 
indicated and potentially curative approach, we and several other transplant centers have 
explored the use of T-cell depleted HLA haplotype disparate marrow or PBSC transplant. In 
1980, our group initially demonstrated the potential of this approach as a treatment for 
children with severe combined immunodeficiency [19] or leukemia [20] who lacked an HLA 
compatible donor. In these initial cases, we showed that marrow transplants from HLA half- 
matched partial donors depleted of T-cells by lectin agglutination and E rosette depletion 
could engraft and reconstitute hematopoietic as well as T and B cell line function without 
either acute or chronic GVHD. Of 80 patients with SCID we have transplanted using this 
approach since that time, 70% survive, durably engrafted, with full T-cell, and in patients 
pretreated with myeloablative conditioning, B cell function.[21] The overall incidence of acute 
GVHD in this series is 7%; no patients developed chronic GVHD. Our experience with HLA 
haplotype matched parental grafts depleted of T-cells by this technique has been replicated 
in several centers throughout the United States, Europe and Asia, the largest experiences 
other than ours being at Duke University,[22] Ulm University [23] and UCSF.[24] 
Unfortunately, centers employing antibody based methods of T-cell depletion have been less 
successful in preventing lethal GVHD,[25] likely reflecting the fact that these methods only 
deplete T-cells by 1.5-2 log10 while the lectin agglutination E rosette depletion technique 
consistently depletes 3-3.5 log10 T-cells. Consistent with this hypothesis are the recent results 
of trials evaluating transplants of HLA haplotype disparate parental PBSC transplants 
depleted of T-cells by positive selection for CD34+ progenitor cells by immunoabsorption to 
anti:CD34 conjugated immunomagnetic beads and selection on the Clinimacs device,[26] 
this approach achieves a 4.0 x log10 depletion of T-cells. 
 
Initial experience with HLA haploidentical parental SBA-E- marrow grafts in the treatment of 
leukemia again demonstrated their capacity to abrogate GVHD.[20, 27] However, these 
transplants were associated with an unacceptably high incidence of graft failure. Our 
transplant program then demonstrated that these graft failures were mediated by residual 
host T-cells that exhibited cytotoxic activity specifically against donor unique HLA alleles.[28- 
30] Subsequently, by step-wise modification of preparatory cytoreduction protocols to include 
additional T-cell targeted immunosuppressive agents, specifically anti-thymocyte globulin 
and thiotepa, our group and the transplant program at the University of Perugia developed

presented by no more than 1 or 2 HLA alleles inherited by the donor.[41, 42] Since the 
Amended:  07/30/15 
Page 9 of 47 
 
 
depleted transplants to < 3% in HLA-matched or 1-2 allele disparate patients [31, 32] and < 
10% in HLA haplotype disparate patients.[33, 34] These incidences are equivalent to those 
recorded after unmodified marrow grafts of similar HLA disparity.[35] 
 
Using such effective conditioning regimens, our group has shown that both SBA-E-BMT and 
CD34+ E-PBSCT can achieve consistent engraftment and extended disease-free survival 
rates of 70% in adults transplanted for high risk AML in 1° or 2° CR or high risk ALL in 1° CR 
when HLA- matched related or unrelated donors are employed.[32, 34] The Perugia group 
has also recorded comparable outcomes for patients receiving CD34+ T cell depleted PBSC 
transplants from HLA-matched related donors after the same conditioning.[36] However, at 
the same time, the Perugia group has been extensively evaluating related HLA-haplotype 
disparate transplants, initially employing SBA-E- BMT and, more recently, CD34+ T cell 
depleted PBSC transplants fractionated with the Miltenyi Clinimacs device. Their studies 
have clearly demonstrated the potential of such transplants to achieve a high incidence of 
durable engraftment (>90%), and extremely low rates of both acute and chronic GVHD.[33] 
However, extended disease-free survival rates recorded for such patients with AML or ALL 
transplanted for high risk disease is 1° CR or in 2° CR have been inferior to those achieved 
with the same conditioning and T-cell depleted grafts from HLA-matched donors. Strikingly, 
the difference in results between the HLA matched and HLA haplotype disparate transplants 
do not reflect differences in rates of engraftment, acute or chronic GVHD or relapse. Rather, 
they are due to a marked increase in mortality due to infections in recipients of HLA 
haplotype- disparate grafts.[33, 37] 
 
Furthermore, this increase in infection-related mortality is principally due to infections caused 
by reactivated latent viruses, principally CMV, and to a lesser extent adenovirus. While the 
risk of reactivation of CMV in seropositive adult patients is approximately 50% in recipients of 
allogeneic HLA-matched transplants, be they related or unrelated, T-cell depleted or 
unmodified, clinical infections, which develop between 1-5 months post transplant, can be 
cleared with current antiviral drugs in all but 3-5% of patients treated.[38] In contrast, the risk 
of serious CMV infection in HLA haplotype disparate seropositive recipients is higher and the 
period of risk may extend to a year post transplant. Furthermore, these infections often fail to 
clear despite prolonged antiviral therapy. As a consequence, the mortality of such infections 
has ranged from 15-30%.[33] 
 
The basis for this striking disparity in sensitivity to life-threatening CMV infections is still 
unclear. However, since several studies have demonstrated clearance of CMV infection post 
HSCT occurs only in individuals who develop CMV-specific cytotoxic T-cells [39, 40] it is 
reasonable to hypothesize that the failure of certain of these patients to clear CMV infection 
may reflect a failure to generate effective CMV-specific T-cell immunity early after viral 
reactivation. 
 
Recent findings from our laboratory provide a plausible reason why such failures might occur 
more frequently in a recipient of an HLA haplotype disparate graft. We have been evaluating 
T-cell responses generated by seropositive donors against a pool of 15-mer peptides 
spanning the sequence of CMVpp65, the CMV protein that most commonly elicits cytotoxic 
T- cell responses. These studies have shown that normal seropositive donors maintain 
responses directed against only 1-2 immunodominant peptide epitopes of CMVpp65 that are

frequencies of clonogenic CMV-reactive CTL precursors in the circulation are 1-5/ 104 T- 
cells, only these immunodominant CMV pp65-specific T-cells would be expected to be 
transferred to a patient in a T cell depleted transplant that provides 1-10 x 104 T-cells/kg 
recipient weight. In an HLA-matched recipient, these immunodominant T-cells would be able 
to consistently interact with CMV-infected tissues of the host since all epitope-presenting 
HLA alleles are also shared by the host. In contrast, in an HLA haplotype- disparate 
recipient, the transferred CTLp will only be functional if the T-cells transferred recognize 
immunodominant epitopes presented by HLA alleles shared by the host. If, on the other 
hand, donor CMV-specific T-cells are restricted by HLA alleles on the haplotype not shared 
by the recipient, they will not recognize, respond to, or control CMV infected cells of the 
host.43 In such patients, effective T-cell immunity will only be provided when new T-cells, 
generated from hematopoietic progenitors in the graft, develop within the host thymus and 
there became restricted by HLA alleles of the host. In patients 40-65 years of age, this may 
not occur until 12 months post transplant.[43, 44] 
 
In fact, we have found that, in 46% of the HLA haplotype matched transplant donors we have 
tested, CMV T-cells generated from the blood in response to pools of overlapping 15-mers of 
CMVpp65 are exclusively restricted by HLA alleles not shared by the transplant recipient. 
Furthermore, we have found that CMV infections occurring in two children who received such 
transplants were both exceptionally severe and protracted, and resolved only after several 
months of antiviral drugs. In these patients, CMV-specific T-cells were ultimately generated 
from transplanted precursors that were educated in and restricted by HLA alleles expressed 
on the host thymus.43 
 
To circumvent these limitations to the effectiveness of HLA haplotype disparate grafts, several 
approaches have been proposed and explored as adjuncts to T-cell depleted HSCT including: 
co-administration of large numbers of donor T-cells selectively depleted of alloreactive T-cells 
capable of initiating GVHD,[45] co-administration of unselected donor T- cells transduced to 
express a “suicide gene”, such as HSV thymidine kinase, so that they can be eliminated if 
they induce GVHD,[46] and adoptive transfer of virus-specific or tumor- reactive T-cells 
sensitized with viral or tumor epitopes presented only by HLA alleles shared by donor and 
recipient.[47]43 The first approach has been effective in murine models but has had limited 
success in human trials because T-cells in outbred humans do not respond to different 
alloantigens all at once. As a result, in vitro treatments used to deplete alloreactive cells 
remove only a fraction of these cells and do not consistently prevent GVHD. The 
second approach has recently shown promise in one multicenter trial.[46] However, while 
GVHD could be abrogated in recipients of suicide vector modified T-cells by treatment with 
acyclovir; this treatment also eliminates virus-specific T-cells. As a result, long term results 
were not significantly different from these reported from HLA-haplotype disparate T-cell 
depleted grafts alone.[33] The third approach is a rational proposal but has thus far not been 
evaluated because identification of immunogenic viral epitopes that can be presented by 
HLA alleles other than HLA A0201 and other prevalent HLA alleles is still rudimentary. 
Furthermore, until recently [41] the logistics of production of T-cells specific for subdominant 
epitopes has been limiting. 
 
In this protocol, we propose to examine another approach which could facilitate

of the patient’s HLA haplotypes and further improve the consistency of durable 
engraftment and the quality of reconstitution: the concomitant use of two T-cell 
depleted transplants, one expressing the genotype HLA haplotype of the patient’s 
father; the other, the genotype HLA haplotype of the mother. 
 
The scientific data supporting the use of biparental T-cell depleted hematopoietic progenitor 
cell transplants was provided initially in the first papers describing the use of allogeneic T-cell 
depleted transplants as a method for preventing GvHD in histocompatible mice.  In 1975, von 
Boehmer, Nobholz and Sprent [48] demonstrated that co transplantation of CBA/J and DBA/2 
marrow and spleen cells depleted of T-cells by treatment with a T-cell specific antibody into 
CBAXDBA F1 hybrid mice resulted in durable split chimerism in lymphoid and hematopoietic 
lineages, with the fraction of cells derived from each donor maintained for over 6 months of 
observation post transplant. In this study, they also demonstrated that T-cells generated in 
the host from each parental donor were not reactive against cells of either the F1 hybrid host 
or the fully allogeneic second donor.  However, they were fully responsive against third party 
H-2 disparate hosts.  In a second study, they further demonstrated that engrafted T-cells 
from either donor would also cooperate with, and provide effective help to, B cells of the 
other donor’s H-2 type in the generation of antibody responses to sheep red cells.[49] 
 
In our early studies of HLA haplotype disparate parental T-cell depleted SBA-E-BMTs in the 
treatment of children with SCID, we had three patients who did not promptly engraft following 
a transplant from one parental donor who then received secondary transplants from the other 
parent. Each of these patients subsequently developed biparental mixed chimerism. Again, 
as n the murine model, the functional T-cells subsequently generated in vivo from precursors 
in the graft were mutually tolerant, as evidenced, in vitro, by their failure to respond to either 
parent’s cells or cells from the patient in mixed lymphocyte culture or T-cell mediated 
cytolysis assays, and, in vivo, by their continued coexistence and the absence of any graft 
vs. host disease.[50] More recently, we have also shown that transplants of human T-cell 
depleted CD34+ progenitors isolated from 2 HLA non-identical allogeneic cord blood grafts 
on the Clinimacs device in immunodeficient NSG mice also potentiate engraftment induce a 
durable state of dual chimerism suggesting mutual tolerance.[51] 
 
Thus, based on these early studies of T-cell depleted marrow grafts in murine models, our 
recent studies of the engraftment of CD34+ progenitors from double cord blood transplants 
and our own early studies of children with SCID who received, sequentially,  transplants of 
SBA-E- T-cell depleted marrow from both parents, we hypothesize that biparental transplants 
will: 
 
1)  Provide consistently higher doses of CD34+ progenitor cells and, like double cord blood 
grafts potentiate engraftment 
 
2)  Result in durable mixed chimerism with progenitors from both donors contributing to all 
hematopoietic and lymphoid lineages 
 
3)  Increase the probability that limited but sufficient numbers of immunodominant T-cells will be 
transferred that can recognize viral epitopes presented by HLA alleles on either haplotype 
shared by the host

absence of acute GvHD or other alloimmune or autoimmune disorders, and, in vitro, by 
absence of reactivity of engrafted cells from either donor against cells of the host or the other 
transplant donor in mixed leukocyte reactions or assays of cytokine and cytotoxic T-cell 
responses. As a result of this tolerance, these patients will also be rendered tolerant of 
adoptively transferred antigen-specific T-cells from either parent. 
 
5)  Cooperate in the generation of new, lymphoid progenitor-derived antigen-specific T-cells in 
the host thymus capable of interacting with antigen presented by HLA alleles shared by each 
donor and the host, thereby securing for the host the capacity to respond to pathogens with 
T-cells restricted by HLA alleles on either the maternal or paternal haplotype 
 
6)  Allow the engraftment of NK cells from both parental donors thereby enhancing NK-mediated 
resistance to the host’s leukemia [52] 
 
An additional advantage of biparental T-cell depleted transplants to the host in terms of 
enhanced T-cell mediated resistance to residual leukemia is suggested by the recent studies 
of Ceciri et al.[53] These investigators observed that among patients with AML who had 
relapsed following an HLA haplotype disparate transplant, fully 30% of the AMLs exhibited 
deletion mutations of segments of the host’s unique chromosome 6, including the complex of 
genes encoding the entire host unique HLA haplotype. As a result, the AML blasts were 
rendered unrecognizable to either alloreactive or tumor-antigen-specific HLA restricted T- 
cells of the donor. Biparental transplants, by permitting the generation of antigen-specific T- 
cells restricted by HLA alleles of either parental HLA haplotype should reduce this possibility.

OVERVIEW OF STUDY DESIGN/INTERVENTION 
 
4.1 
Design 
 
This is a pilot study to provide initial data on the feasibility, efficacy and safety of biparental 
HLA haplotype disparate T-cell depleted transplants in the treatment of patients with high risk 
forms of acute or chronic leukemia, NHL, MDS or other lethal disorders of hematopoiesis 
who lack an HLA-matched or 9/10 HLA allele compatible donor. The trial allows selection of 
either of two myeloablative regimens for preparatory cytoreduction that have secured 
engraftment of HLA non-identical and haplotype disparate T-cell depleted transplants. 
Thereafter, two GCSF-mobilized PBSC transplants depleted of T-cells by positive selection 
for CD34+ progenitors on the Clinimacs device will be administered. The paired CD34+ TCD 
PBSC transplants will be derived from the two parents of the patient, or from first degree 
relatives, each providing one of the two genotypically identical HLA haplotypes inherited by 
the patient. Patients will be clinically evaluated for engraftment, incidence and severity of 
acute and chronic GVHD, transplant related complications, relapse and both overall and 
disease-free survival. Stopping rules are incorporated to insure against an excess risk of 
graft failure, severe GVHD or transplant-related mortality. Patients will also be evaluated 
sequentially for state of chimerism, and for quality and extent of immune reconstitution, 
particularly as reflected by tolerance or alloreactivity against donor, host or third party 
alloantigens, and the HLA restrictions of antigen-specific T-cell responses.

syndrome (MDS) or other lethal disorders of hematopoiesis who fulfill eligibility requirements, 
consent to treatment and have two healthy consenting donors, each bearing one of the 
patient’s HLA haplotypes will receive myeloablative conditioning consisting of one of the 
following regimens: 
 
1)  1375-1500 cGy hyperfractionated total body irradiation (depending on age and stage of 
disease) with lung shielding, followed by thiotepa (5 mg/kg/day x 2 or 10mg/kg/day x 1) 
and Fludarabine 25mg/m2/ day x 5 days. 
 
2)  Fludarabine 25 mg/m2/day x 5, melphalan 70 mg/m2/day x 2 and thiotepa 5 mg/kg/day x 
2 (or 10mg/kg/day x 1) 
 
 
All patients will also receive antithymocyte globulin (ATG) (thymoglobulin 2.5 mg/Kg/day x 3 
or equine ATG 15 mg/kg/day x 3 if thymoglobulin is not tolerated) during pre-transplant 
conditioning to deplete radiation or chemotherapy resistant host T-cells that could hamper 
engraftment. 
 
Following preparative cytoreduction, all patients will receive the two GCSF mobilized PBSC 
transplants depleted of T-cells by positive selection of CD34+ progenitor cells with the 
CliniMACS system. The targeted dose progenitor cells for each transplant will be > 5 x 106 
CD34+ cells/kg with the dose of T-cells limited to < 2.0 x 104/CD3+ cells/kg. The cell doses of 
each transplant will be adjusted to provide the same dose of CD3+ T-cells/kg. +/- 
0.1X104CD3+ T-cells/kg. 
 
 
Following transplantation, the patients will receive transfusions and supportive care 
according to the guideline of the Transplant Service in Pediatrics and Medicine. These 
guidelines will also be invoked for prophylaxis and treatment of infectious complications. 
 
The patients will then be evaluated sequentially for toxicities, engraftment, acute and/or 
chronic GVHD, the kinetics and quality of hematopoietic and immune reconstitution, and both 
relapse-free survival and overall survival.

lung receives 800 cGy. The blocked areas of the chest will be boosted with high-energy 
electrons so that the cumulative chest wall dose is approximately 1500 cGy. This insures that 
marrow sites in the ribs are adequately treated. 
 
If general anesthesia is required for TBI administration (e.g. young children), a dose of 
200cGy q12h x 7 doses to a total dose of 1400 cGy may be given. 
 
In addition, male patients receiving transplants for ALL or AML will receive an additional dose 
of 400 cGy to the testes to reduce the risk of relapse from leukemia cells in this privileged 
site.

antiviral agent vidarabine, 9-ß-D-arabinofuranosyladenine (ara-A) that is relatively 
resistant to deamination by adenosine deaminase. The chemical name for fludarabine 
phosphate is 9H-Purin-6-amine, 2-fluoro-9-(5-O-phosphono-ß-D-arabinofuranosyl). 
Fludarabine phosphate is rapidly dephosphorylated to 2-fluoro-ara-A and then 
phosphorylated intracellularly by deoxycytidine kinase to the active triphosphate, 2-fluoro- 
ara-ATP. This metabolite appears to act by inhibiting DNA polymerase alpha, 
ribonucleotide reductase and DNA primase, thus inhibiting DNA synthesis. The 
mechanism of action of this antimetabolite is not completely characterized and may be 
multi-faceted.

5.3 The CliniMACS System for Positive Selection of CD34+ Progenitor Cells and 
Depletion of T-Cells. 
 
 
The CliniMACS System (Miltenyi Biotec, Auburn, CA) including the CliniMACSplus Instrument, 
a CliniMACS Tubing Set, the CliniMACS CD34 Reagent and the CliniMACS PBS/EDTA 
Buffer is intended for the selection and enrichment of human CD34 positive hematopoietic 
progenitor cells from a leukapheresis product. 
 
The CD34 antigen is a cell membrane glycoprotein expressed by early hematopoietic stem and 
progenitor cells. The CD34 positive cell separation process may be useful in several areas of 
clinical stem cell transplantation, including purging of tumor cells, T-cell depletion, ex vivo cell 
expansion and gene therapy. When re-infused after myeloablative chemotherapy, CD34 
positive peripheral blood progenitor cells have been shown to reconstitute all hematologic 
lineages and exhibit both short and long term repopulating capacities. 
 
The ClinMACS System uses selective CD34 monoclonal antibodies conjugated to super- 
paramagnetic particles. The CD34 positive target cells are selected in an automated 
continuous flow separation system. 
 
The CD34 positive cells are specifically labeled for selection by incubation with the CliniMACS 
CD34 Reagent. After unbound reagent is washed from the suspension, the cells are ready for 
the automated separation process. The CliniMACS System passes the antibody-labeled 
suspension, the cells are ready for the automated separation process. The CliniMACS System 
passes the antibody-labeled suspension through a column in which strong magnetic gradients 
are generated. The Selection Column retains the magnetically labeled CD34 positive cells, 
while unwanted cells flow through the Selection Column and are collected in the Negative 
Fraction Bag. The system performs several washing steps, disposing most of the liquid into the 
Buffer Waste Bag. The Separated CD34 positive cells are released from the column by 
removing the column from the magnetic field and cluting the cells into the Cell Collection Bag. 
 
 
 
The components of the CliniMACS System include: 
 
 
5.3.1 The CliniMACS Instrument 
 
 
The CliniMACS Instrument is a bench-top instrument consisting of a supporting structure to hold 
the column/tubing assembly and various bags, a series of valves through which the tubing set is 
fitted, a magnet between the poles of which the separation column is placed, a peristaltic pump

interface and a computer touchpad with a display window. The instrument is operated at 
ambient temperature and it is intended to be multi-use item. 
 
The software for the CliniMACS Instrument controls the function of the electromechanical 
components of the instrument and the user interface. Two separate computers, one a micro- 
controller located on a control board of the CliniMACS Instrument and the second a PC 
compatible computer which operates the user interface are incorporated with the instrument. 
Software Version 2.31, the current version of software is directly traceable to the version of 
software utilized in pre-clinical testing and European Safety trials, and has been inspected and 
approved by TÜV product services with the CE Mark. 
 
5.3.2. CliniMACS Tubing Set 
 
 
The CliniMACS Tubing Set consists of a tubing element combined with a pair of proprietary cell 
selection columns. These form a closed, sterile system for processing the cells. The separation 
column is a proprietary component of the CliniMACS System consisting of a plastic column 
housing with polypropylene frits in each end. The interior of the column housing is filled with a 
matrix of sub-millimeter iron beads coated with a heat-cured biocompatible resin. The columns 
are placed at appropriate locations in the CliniMACS Tubing Set to facilitate the cell selection 
process. The first column serves as a device to remove components that bind non-specifically 
to the column. The second column which is placed within a magnetic field performs the actual 
cell selection. The columns are incorporated sterile as part of the tubing set and are intended 
for single use only. 
 
The tubing element consists of a series of tubes, connectors, spikes, Luer locks, and collection 
bags. The tubing of the tubing element is comprised of materials that have been qualified for 
use in this application by testing to ISO 10993. The principal constituents are polyvinyl chloride 
(PVC) and silicone.  The connectors are made of various polymers (e.g., ABS and PVC) 
suitable for use in a blood contact environment. They are solvent bonded to the PVC tubing. 
The silicone pump tubing is softened with petroleum ether for manufacturing and mechanically 
fixed to connectors. The cell wash bags are composed of PVC. 
The CliniMACS Tubing Set is packaged in a thermoformed tray and heat sealed with a Tyvek® 
lid. The CliniMACS Tubing Set is sterilized by ethylene oxide gas in a validated sterilization

Whenever possible, in addition to these baseline tests, a 25ml aliquot of blood will be drawn 
within 1 month prior to transplant which will be used 1) to establish a patient derived EBV 
transfused B cell line as an antigen presenting cell 2) to analyze the patient’s HLA restricted T- 
cell responses to EBV and CMV and 3) to provide irradiated PBMC to test responses of 
engrafted T-cells against the patient’s alloantigens. 
 
8.2. 
Pretreatment evaluation of the two donors 
 
Whenever possible, in addition to these baseline tests, donors will be asked to consent to the

transplant which will be used to 1) establish a donor-derived EBV transfused B cell line as an 
antigen presenting cell of donor origin, 2) to analyze the donor’s HLA-restricted T-cell responses 
to EBV and CMV and 3) to serve as a donor-type target for mixed lymphocyte reactions testing 
whether the engrafted donor T-cells are tolerant or alloreactive in nixed leukocyte culture post 
transplant. 
 
 
 
9.0 
TREATMENT/INTERVENTION PLAN 
 
9.1 Admission for Transplantation 
 
Patients will be admitted to Memorial Hospital Allogeneic Transplant Services in Pediatrics or 
Medicine. All orders will be administered upon admission as per institutional standard of 
practice. 
 
9.2 Cytoreduction Regimen in Preparation for Transplantation: 
 
Patients will be assigned to one of two cytoreductive regimens depending on their disease 
and treatment history. 
 
Regimen 1 will be the regimen of choice for those patients with hematologic malignancies 
who are able to tolerate TBI and who are without significant treatment associated 
comorbidity. 
 
Regimen 2 will be the regimen of choice for patients with non-malignant, lethal disorders of 
hematopoiesis and immunity, and those patients with hematologic malignancies who cannot 
receive TBI due to extensive prior treatment and comorbidity. 
 
9.2.1a  Regimen 1 - Hyperfractioned Total Body Irradiation, Thiotepa and Fludarabine. 
 
Hyperfractionated TBI is administered at a dose rate of < 20 cGy/minute. Doses of 125 
cGy/fraction are administered at a minimum interval of 4 hours between fractions, three 
times/day for a total of 11 or 12 doses (1375 or 1500 cGy) over 4 days (Day -10, -9, -8, and - 
7). 
 
1500 cGy will be administered to children < 18 years of age with ALL > 1oCR, since the 
higher dose has greater anti-leukemic activity and is well tolerated. Sequential doses are 
administered in an anterior/posterior or lateral orientation. Lung blocks will be used to reduce 
the lung dose to 800 cGy. The blocked chest wall areas will be boosted with high-energy 
electrons so that the cumulative chest wall dose is approximately 1500 cGy, so as to insure 
that marrow sites in the ribs are adequately treated. 
 
If general anesthesia is required for TBI administration (e.g. young children), a dose of 
200cGy q12h x 7 doses to a total dose of 1400 cGy may be given. 
 
In addition, male patients receiving transplants for ALL will receive an additional dose of 400 
cGy to the testes to reduce the risk of relapse from leukemia cells in this privileged site. 
 
9.2.1b Thiotepa 


MEMORIAL SLOAN-KETTERING CANCER CENTER 
IRB PROTOCOL 
IRB#: 12-053A(7) 
Amended:  07/30/15 
Page  23 of 47 
 
 
Thiotepa: 5mg/kg/day IV over approximately 4 hr qd x 2 days (Day-6 and Day -5) or 10mg/kg 
for one day (Day -5). 
 
In select cases in which the G-CSF mobilized PBSC must be harvested a day later than 
requested due to a scheduling issue with the donor or Stem Cell Processing Laboratory, 
there may be a day of rest between the last day of radiation and the first day of thiotepa 
(Donor can only donate on Friday). Alternatively, if the marrow must be handled a day earlier 
than requested, Thiotepa may be given in a single dose of 10mg/Kg on day -6. Thiotepa 
dosing will be adjusted if patient is >125% of ideal body weight and will be calculated based 
on adjusted ideal body weight, as per MSKCC standard of care guidelines. 
 
9.2.1c Fludarabine 
 
Fludarabine will be administered at a dose of 25 mg/M2 IV over approx. 1/2hr qd x 5 days (d - 
6 through d -2). The first dose will begin approximately 8 hours prior to the thiotepa. On d-5 
fludarabine will be administered first followed by Thiotepa 8-10 hours later. On days -4, -3, - 
2, Fludarabine will also be administered approximately 2 hours prior to ATG. Fludarabine 
may be adjusted in the case of renal toxicity, as per MSKCC standard of care guidelines. 
 
9.2.1d Rabbit antithymocyte globulin (thymoglobulin®) 
 
Rabbit ATG will be given to all transplant recipients. Rabbit antithymocyte globulin 
(Genzyme) will be administered on days -4, -3, and -2 at a dose of 2.5 mg/kg (actual body 
weight/day). If the patient has a history of allergy or intolerance to rabbit ATG, equine 
antithymocyte globulin at a dose of 15 mg/kg x 3 doses may be used. If severe reaction is 
encountered after the 1st dose of ATG, the second and third doses can be delayed until day 
+5 and day +7. Methylprednisolone 1 mg/kg will be given as premedication. Additional 
medications to prevent or treat reactions will be administered as indicated according to 
institutional guidelines. ATG dosing will be adjusted if the patient is > 125% of ideal body 
weight and will be calculated based on adjusted ideal body weight, as per MSKCC standard 
of care guidelines. 
 
Please note: patients weighing < 10 kg will have medications calculated per kg instead of per 
m2, when indicated. 
 
Because Acetaminophen depletes glutathione and the alkylators require glutathione 
transferase for their metabolism, Acetaminophen administration is discouraged during the 
course of cytoreduction

No GvHD prophylaxis will be administered other than the CliniMACS fractionated T-cell 
depleted transplant. 
 
9.4. Stem Cell Transplantation 
 
9.4.1.    PBSCT 
 
Donor peripheral blood progenitor cells: stimulation, harvesting, isolation and T-cell 
depletion. 
 
For both related donors, GCSF will be administered according to MSKCC standard of care. 
 
Isolation of CD34+ hematopoietic progenitor cells with the CliniMACS TM System, 
Miltenyi Biotec. 
 
The apheresis product is collected from two blood-related, genotypically HLA haplotype 
matched donors. Aliquots of the apheresis product are collected and then tested and 
screened as per blood banking guidelines. The apheresis product is then prepped for the 
CliniMACS Cell Selection System. The mechanism of action of the CliniMACS Cell Selection 
System is based on magnetic-activated cell sorting, which can select or remove specific cell 
types depending on the cell-specific immunomagnetic label used. The apheresis product is 
first co-incubated with the CliniMacs CD34 reagent (antibody-coated paramagnetic particles). 
After magnetic labeling and washing, the cells are passed through a high-gradient magnetic 
separation column in the CliniMACS clinical cell selection device. Magnetically labeled

the effluent fraction and discarded. The CD34+positive cells retained in the column are eluted by 
removing the magnetic field from the column, then washing the cells through the column and 
collecting them. The final CD34+ cell enriched product is concentrated by centrifugation and 
tested before final release for administration. The SOPs from the MSKCC Cytotherapy Lab 
Manual are appended. 
 
Before infusion, the CD34+ cells will be washed in normal saline for intravenous infusion 
containing 1% human serum albumin, and suspended in a volume of 25-50 ml. for 
intravenous administration. 
 
Throughout the process, critical control points and associated assays are identified and 
performed on each cellular therapy product. Aliquots of the same product sample are taken 
for in-process and final product testing. After each step (apheresis, platelet washing, CD34 
labeling and washing, enrichment), QC testing includes; Sterility. Endotoxin, gram stain, 
Total nucleated cells (TNC), flow cytometry phenotype/analysis of CD45, CD34, and CD3, 
and viability assessed by 7-AAD is assessed. To ensure sterility, 14-day sterility tests are 
performed for in-process sterility testing and a gram stain is performed on the final product 
prior to release. 
 
9.4.2 Transplantation of the T-cell depleted stem cells. 
 
For the first patient, the CD34+T-cell depleted peripheral blood progenitor cell graft 
expressing the paternal HLA haplotype, suspended in a volume of approximately 20-30 ml 
will be infused intravenously over 10-15 minutes with monitoring of vital signs. The second 
CD34+ T-cell depleted graft expressing the maternal HLA haplotype will be infused 
approximately 30 minutes thereafter. For subsequent patients, the order of transplants will be 
alternated as to the HLA haplotype of the first donor (i.e. maternal or paternal HLA sharing 
graft first). Each patient will be premedicated as for blood product transfusions. 
 
9.5. 
Supportive Care 
 
a.    Prophylaxis against infections 
 
Standard of care guidelines will be followed for prophylaxis against post transplant infections 
by opportunistic organisms, including Pneumocystis jiroveci, fungal organisms, DNA 
herpesviruses and more specifically CMV. 
 
b.   Prophylaxis against menorrhagia 
 
All post-pubertal females will receive prophylaxis against menorrhagia according to our 
standard of care guidelines. 
 
c.    Transfusions 
 
Following initiation of the pre-transplant cytoreduction, all blood products for transfusion, with 
the exception of the peripheral blood stem cell, will be irradiated to 3,000 cGy to inactivate 
lymphocytes capable of initiating lethal GvHD. Blood products are irradiated in the blood 
bank, using a cesium gamma emitter.

11.0 TOXICITIES/SIDE EFFECTS 
 
Patients recruited to this transplantation trial are individuals who are either referred by 
physicians or self-referred for marrow transplantation as a potentially curative treatment for 
their malignancy. Prior to consideration for transplant, all patients undergo a series of 1-3 
hour consultations discussing the risks and potential benefits of an allogeneic stem cell 
transplantation and the different procedures which will be a normal part of the transplant 
course. The risks and potential benefits of the transplant procedure, as well as the 
participation in any given research, experimental, or therapeutic protocol are also discussed. 
 
On this study, we will be capturing and tracking Grade 3-5 toxicities which occur within 30 
days post-HSCT and are potentially attributable to treatment on study. Toxicities which are 
attributable to underlying malignancy and/or were present prior to initiation of therapy will not 
be tracked. Please see section 17.2 for Serious Adverse Event reporting.

The risks of short-term treatment with G-CSF are likely negligible. However, administration of 
GCSF is frequently associated with low grade fever and low back pain which usually resolves 
within one day following cessation of GCSF treatment. Furthermore, there has now been one 
recorded patient who developed acute splenomegaly and splenic rupture in response to high 
dose GCSF. The bone pain may require treatment with analgesics. The risks of a 
leukapheresis are negligible, involving an occasional vasovagal response to venipuncture 
and the minimal hemodynamic alterations associated with single unit phlebotomies. To 
protect against these risks, leukapheresis are conducted in the Blood Bank Donor Room with 
full medical and nursing supervision and support systems to address adverse events. 
 
11.1.1 Total Body Irradiation 
 
Likely 
 
 
Nausea and vomiting - virtually all patients will experience nausea and vomiting after 
irradiation. This can be diminished somewhat with mild anti-emetics. Strong sedatives or 
phenothiazine derivatives should be avoided just before radiation treatment, as they 
frequently cause excessive drowsiness and/or symptomatic orthostasis, which prevent 
delivery of TBI done in the standing position. 
 
 
Myelosuppression is the major dose-limiting toxicity. 
 
 
Hyperpigmentation - most patients will get some degree of hyperpigmentation within 2-3 
weeks of transplantation. 
 
 
Increased risk of infection

 
Mucositis - most patients will develop moderate to severe mucositis of the oral and GI tracts, 
which will be managed with aggressive nursing mouth care, analgesics and prophylactic 
antifungal and antiviral agents. 
 
 
Late effects - there is the possibility of cataract formation. Although mild cataracts may 
occur in up to 70% of cases with single dose TBI, we have seen cataracts in < 30% of 
patients treated with hyperfractionated TBI. 
 
 
Sterility is extremely common following total body irradiation and administration of alkylating 
chemotherapy; the risk increases with the number of years since puberty. 
 
Less Likely 
 
 
Parotitis - some patients will experience symptomatic parotitis within the first 24 hours post 
radiation. This resolves spontaneously over several days. 
 
 
Diarrhea - most patients develop some diarrhea in the first week post irradiation. This can 
be treated symptomatically. 
 
 
Fever – low grade fever [greater than 38°C] may occur for 24 hr post irradiation. This can be 
treated symptomatically. 
 
 
Erythema - this may occur in patients within 24 hours and resolves in 2-3 days. 
 
 
Hypothyroidism has been reported in small numbers of adult patients following TBI plus 
alkylating chemotherapy, and this will be routinely monitored post transplant with hormonal 
replacement as indicated. 
 
 
There is a possibility that secondary malignancies may develop, particularly due to the 
combined effects of radiation and an alkylating agent [cyclophosphamide]. The age-adjusted 
incidence of secondary cancer in transplant patients after radiation and chemotherapy has 
recently been estimated to be 6.7 times higher than that of first cancers in the general 
population; and most of these were non-Hodgkin's lymphomas. 
 
11.1.2 Thiotepa 
 
Likely 
 
 
Myelosuppression is the major dose-limiting toxicity, occurring regularly at doses 
>405mg/m2. Other non-fatal toxicities have been observed almost exclusively after 
administration of thiotepa at doses greater than 1000mg/m2. 
 
 
Increased risk of infection. 
 
 
Cutaneous erythema and bronzing is seen in most patients given 900mg/m2. Erythema 
develops 4-14d after the first dose and may last up to 3wks. Bronzing may persist for 
months. 
 
Less Likely 
 
 
Nausea, vomiting, diarrhea - occasional, rarely severe.

Rare but Serious 
 
 
CNS toxicity manifested by mild cognitive dysfunction, disorientation, confusion, irritability, 
bizarre behavior, is usually not observed at doses <1000mg/m2. 
 
 
Interstitial pneumonia 
 
 
Renal failure 
 
 
Transient hepatic transaminase elevations are occasionally seen, but rarely severe. 
 
11.1.3 Fludarabine 
 
Likely 
 
 
Nausea, vomiting, mouth sores, stomach cramps and diarrhea, jaundice, and elevations of liver 
enzymes. 
 
 
Scaling and redness of the skin, which is usually of short duration. 
 
 
Transient but significant myelosuppression at the doses called for in this protocol.  Fludarabine 
is also profoundly immunosuppressive.  These toxicities place the patient at increased risk for 
infections for periods of 1-2 months. 
 
 
Transfusions of platelets and red blood cells 
 
Rare but Serious 
 
 
Effects on the nervous system are not usually seen at the fludarabine dose used in this 
protocol, but, when they occur, can include cerebellar dysfunction with loss of balance and 
trouble walking, blurring of vision or, in extremely rare cases, blindness, and mental agitation or 
confusion. 
 
11.1.4 Melphalan 
 
Likely 
 
 
nausea and vomiting - Diarrhea 
 
 
mucositis 
 
 
myelosuppression and pancytopenia, with increased risk of infection 
 
 
elevated liver function tests 
 
 
sterility 
 
 
alopecia 
 
 
fever 
 


11.1.8  Rabbit Antithymocyte Globulin (Thymoglobulin) 
 
The ATG to be used in this trial is a purified preparation of rabbit gamma globulin containing 
high concentrations of antibodies against human lymphocytes.   The preparation may contain 
low levels of antibody that cross-react with human platelets, white cells or red cells.  The 
potential side effects of ATG are: 
 
Likely 
 
 
Fever, shaking, chills and lowered blood pressure:  These are regularly observed, particularly 
during initial infusions of the rabbit globulin.  They probably result from a breakdown of cells 
binding the antibody. 
 
 
Skin rash and itching:  A frequent complication which is probably due to minor allergic reactions 
to rabbit globulin.   These symptoms will usually be prevented by or controlled with anti- 
histamines as well as with concomitant administration of corticosteroids. 
 
 
Platelet and white cell count depression:   These are frequently observed and are probably 
caused by the binding of the rabbit antibody to human blood elements.  Platelet transfusions will 
be administered to reduce the chance of bleeding or life threatening hemorrhage. 
 
 
Less Likely 
 
 
Serum sickness:  Approximately 30% of patients treated with rabbit globulin will develop a late 
immune reaction to the globulin resulting in serum sickness 3-10 days after the administration. 
This may lead to severe skin rashes, mouth and vaginal sores, pain and swelling of the joints, 
or kidney damage.  Serum sickness is transient and its damage reversible but it may require 
prolonged treatment with corticosteroids. 
 
 
 
 
 
Rare, but potentially serious

Amended:  07/30/15 
Page 32 of 47 
 
 
 
Anaphylaxis:   A rare but severe allergic reaction which may cause a life threatening drop in 
blood pressure, wheezing and difficulty breathing and severe hives.  This complication can be 
treated with anti-histamines and steroids. 
 
 
 
11.2       Toxicities/Side effects of the transplant and the combined effects of the 
conditioning regimen and transplant 
 
11.2.1      Potential Sensitization to Murine Proteins 
 
Mouse protein antibodies are used in the CliniMACS processing procedures.  If the recipient 
has a pre-existing allergy, he or she may be at risk for allergic reactions during infusion of the 
processed cells, although the residual amount of murine protein in the final product is very low 
(estimated maximum dose for a 50 kg patient would be 30 µg).  To date, no allergic reactions 
are reported in patients receiving cells processed with the CliniMACS System.  Epinephrine and 
antihistamines will be available at the recipient's bedside during the PBSC infusion. 
 
 
 
11.2.2      PBSC Infusion 
 
Symptoms may include changes in heart rate and/or rhythm, changes in blood pressure, fever, 
chills, sweats, nausea, vomiting, diarrhea, abdominal cramping, hemoglobinuria, acute renal 
failure, allergic reactions, respiratory dysfunction, or headache. 
 
11.2.3      Infections 
 
Transplantation puts the patient at higher risk for bacterial, viral, or fungal infections, which are 
potentially  life  threatening.     These  risks  are  potentially  higher  with  TCD  transplants. 
Prophylaxis will be initiated and patients will be closely monitored for signs of infections and will 
receive early and appropriate treatment. 
 
11.2.4      Microbial Contamination of PBSC 
 
There is a potential that processing the leukapheresis product will inadvertently introduce 
microorganisms that could cause infection in the recipient after the cells are infused.  All 
precautions to maintain sterility will be taken.   Cultures of the leukapheresis product and the 
selected product will be obtained to monitor for contamination. 
 
 
 
11.2.5      Graft Failure / Poor Marrow Function 
 
T cell depletion of donor cells is associated with an increased incidence of graft failure in 
allogeneic transplant recipients.  After allogeneic transplantation, the recipient's marrow function 
may be poor and leukopenia, anemia, or thrombocytopenia may result from many causes 
including graft rejection induced by surviving host immune T-cells, or ongoing suppression of 
engrafted donor blood-forming cells by GVHD, certain types of infection (e.g. CMV. HHV6), 
immunosuppressant drugs and other medications.  Graft failure may result in death if not 
reversed.In patients with immune rejection second transplants can be administered with 
immunosuppressive therapy, including non-myeloablative conditioning regimens. For patients 
who are engrafted with donor cells but have severe cytopenia affecting one or more blood cell 
lineages, secondary transplants of CliniMACS fractionated CD34+ T-cell depleted PBSCs may 
be administered to booster and replenish donor hematopoietic cells without conditioning or after

involve any and all organs, including the brain.  Brain damage can result in severe loss of 
Amended:  07/30/15 
Page 33 of 47 
 
 
 
 
It is possible that administration of two T-cell depleted transplants each bearing one of the two 
parental HLA haplotypes might lead to alloreactions between grafts that could increase the risk 
of graft failure, although our own extensive experience with allogeneic cord blood transplants 
that are each partially HLA matched with the patient suggests that engraftment is improved. Our 
own and published experience in mouse models as well as our experience in children with 
SCID who received two T-cell depleted transplants also suggest that overall engraftment is not 
impaired. 
 
It is certainly possible that only one of the two parental grafts will durably engraft and induce 
hematopoietic and lymphoid chimerism and functional reconstitution. This is usually the case 
following double cord blood transplants. However, this dominance has been ascribed to either a 
higher cell dose and viability of one cord blood or the activity of T-cells in the dominant cord. In 
murine models, and limited clinical experience, both T-cell depleted grafts usually contribute to 
sustained chimerism. However, even if, in these patients, one T-cell depleted graft proves to be 
dominant, the biparental grafts, like the cord blood grafts, may induce more rapid engraftment 
and reconstitution and potentially a lower risk of disease relapse. The level of tolerance for 
alloantigens unique to the host and to the second parental donor, as well as the pattern of HLA 
restriction exhibited by virus-specific T-cells both early and late post transplant remain to be 
determined, but the potential for in vivo selection of functional donor T-cells restricted by shared 
HLA alleles could be enhanced by the biparental grafts even if only one ultimately becomes 
dominant. 
 
11.2.6 
Graft-versus-host Disease 
 
Acute or chronic GVHD may develop after allogeneic transplantation that can be disabling and 
can lead to death. GVHD is thought to be initiated by T cells contained in the PBSC graft. 
CD34+ selection and CD3+ depletion reduces the number of T cells in the PBSC but GVHD can 
occur after TCD transplants. Biparental TCD transplants could reduce or possibly increase this 
risk. Acute and/or chronic GVHD will be treated with immunosuppressive drugs as per the 
transplant service guidelines. 
 
11.2.7 
Veno-occlusive Disease (VOD) of the Liver 
 
VOD is a manifestation of damage to the liver by the conditioning regimen that usually develops 
within two weeks after allogeneic transplant and is characterized by at least two of the following: 
 
 
Hyperbilirubinemia (total bilirubin > 2 mg/dL) 
 
Hepatomegaly or right upper quadrant pain, or 
 
Rapid weight gain (> 5% above baseline) 
 
Recipients developing VOD will be monitored closely and will receive appropriate supportive 
care and careful fluid management. TCD is not expected to affect the risk of VOD. 
 
11.2.8 
End Organ Damage 
 
End organ damage of all or any of the major organs, including the brain, may occur as a result 
of cumulative toxicity from anti-neoplastic therapy, reactions to other drugs, and as a result of 
destructive processes (e.g., infection, GVHD, etc.) and may have a fatal outcome. Toxicities 
may occur in any individual patient due to multiple events and cumulative effects that may

Amended:  07/30/15

cognitive or neurologic function.  Data from previous studies do not suggest that the risk of end 
organ damage is appreciably affected by TCD or the preparative regimens to be used in this 
study. 
 
 
 
11.2.9 
Disease Relapse 
 
Allogeneic transplantation using T cell depleted peripheral blood stem cells has, in some cases, 
been associated with an increased incidence of leukemic relapse in patients with chronic 
myelogenous leukemia, compared to recipients who receive unmanipulated donor cells. The 
risk of relapse has not been increased in patients with acute leukemias. Nevertheless, despite 
cytoreduction and a transplant, relapse may occur. 
 
11.2.10 Lymphoproliferative Syndrome 
 
Recipients of TCD allogeneic grafts have an increased risk of developing lymphoproliferative 
syndromes caused by EBV infection.[54, 55] This syndrome should be included in the 
differential diagnosis of recipients with unexplained symptoms such as fever, diarrhea, 
hepatomegaly or lymphadenopathy.  Biopsy evaluation is required to make the diagnosis.  EBV 
PTLD may rapidly progress and can be fatal if not treated.  Management of suspected EBV 
PTLD should be discussed with one of the Protocol P.I.s.  EBV PTLD can be treated with 
rituximab and/or infusion of EBV-specific T-cells/kg from the donor.  Rituximab has been shown 
to induce durable regression in 50 - 70% of cases.[56] However, Rituximab does not enter the 
CNS and is not effective in treating CNS disease. EBV-immune T-cells are experimental, but 
can also induce regression of EBV PTLD without risk of graft vs host disease.[57-59] 
 
11.2.11 Death 
 
Following HLA matched or compatible transplants there is an approximately 5-10% risk of 
treatment related mortality within the first 100 days of transplant due to the risk of severe 
regimen related toxicity, hemorrhage, opportunistic infection, or other complications.  Based on 
reported experience, the risk of transplant-related mortality following single HLA-haplotype 
matched transplants is higher (up to 25%) because of the higher risk of graft failures, GVHD 
and particularly severe viral infections.[33] 
 
12.0 CRITERIA FOR THERAPEUTIC RESPONSE/OUTCOME ASSESSMENT 
 
Definition of events in the post-transplant course important for analysis and treatment 
 
12.1 
Engraftment and Chimerism 
 
Engraftment will be documented by analysis of blood cells, T cells and bone marrow cells for 
chimerism by standard cytogenetic studies at about 1 month, 100 days, 6 months, 9 months (if 
clinically indicated), and 12 months, 18 months (if clinically indicated), and 24 months 
posttransplant or as needed thereafter. 
 
12.2 
Graft failure or rejection 


MEMORIAL SLOAN-KETTERING CANCER CENTER 
IRB PROTOCOL 
IRB#: 12-053A(7) 
Amended:  07/30/15 
Page  35 of 47 
 
 
Primary non-engraftment is diagnosed when the patient fails to achieve an ANC 500/l at any 
time in the first 28 days post-transplant. If the patient's leukemia recurs during this interval, the 
patient is scored as having refractory leukemia. In such a situation, the absence of donor 
hematopoiesis is not evaluable for graft failure or rejection. If host T-cells capable of specifically 
inhibiting donor hematopoietic progenitor growth in vitro are concurrently detected during graft 
failure, a presumptive diagnosis of immune mediated rejection is made.[60, 61] If (1) after 
achievement of an ANC 500/mm3, the ANC declines to <500/mm3 for more than 3 consecutive 
days in the absence of relapse, or, (2) there is absence of donor cells in the marrow and/or 
blood as demonstrated by chimerism assay in the absence of relapse, a diagnosis of secondary 
graft failure is made. If, however, recurrence of host leukemia is detected concurrently, the 
patient is not evaluable for graft failure or rejection. 
 
Patients with evidence of graft failure without evidence of recurrence of host leukemia will have 
additional studies drawn to ascertain cause and define relevant histoincompatibilities.  These 
analyses may include (1) Evaluation of bone marrow aspirates and biopsies for residual or 
recurrent leukemia, when indicated, (2) Culture and/or molecular analyses of marrow and blood 
for viral pathogens potentially causing graft failure including CMV, HHV6 and parvovirus B 19, 
(3) Immunophenotypic and genetic analysis of circulating T-cells and NK cells to ascertain their 
origin and potential function, (4) Analysis of the functional activity of residual circulating 
lymphocytes to determine whether and to what degree they exhibit cytotoxic or cyto-inhibitory 
activity against one of the donors, the host or third party PHA-stimulated blasts or clonogenic 
hematopoietic progenitor cells. If donor-specific reactivity is identified, attempts will be made to 
identify targeted specificities (HLA or minor alloantigens) whenever possible. 
 
Patients who suffer graft failure will be considered for a secondary transplant from one of the 
initial donors. The need for additional immunosuppression or treatment for viral infection prior to 
the secondary transplant will be determined by the results obtained from chimerism and viral 
studies. 
 
12.3. 
Graft-versus-host disease 
 
Standard BMT-CTN and IBMTR systems clinical criteria as defined by Rowlings, et al [62] will be 
used to establish and grade acute GvHD. 
 
To determine the severity of acute GvHD, data will be collected approximately weekly to 
characterize the severity of symptoms and signs caused by GvHD and to evaluate possible 
confounding factors. Real time data collection will include descriptive characteristics of rash and 
estimated body surface area involved, extent of dermal/epidermal separation, identification of 
concomitant causes of increased bilirubin other than GvHD, presence or absence of nausea, 
vomiting or anorexia persistent after engraftment, peak diarrhea volume with annotations 
concerning the presence after engraftment, peak diarrhea volume with annotations concerning 
the presence or absence of urinary mixing and estimates of true diarrhea volume, presence or 
absence of abdominal cramps, presence or absence of frank stool blood or melena, concomitant 
causes of GI symptoms other than GvHD, biopsy results, identification of any agents used for 
treatment and autopsy results. 
 
Patients will be observed for acute and/or chronic GvHD as long as they have not received donor

derived leukocytes infusions (DLI). If at any time, a patient receives DLI, that time will represent 
the end-time for evaluation of GvHD. Graft-versus-host disease occurring after DLI infusions will 
be analyzed separately. 
 
Patients with moderate to severe acute GvHD (grade II-IV) will be treated in standard fashion 
with high-dose I.V. methylprednisolone (2-20mg/kg/day) or in combination with other 
immunosuppressants as per ongoing trials on GvHD. Patients failing to respond to steroids will 
be considered for treatment with experimental treatments available at the time of diagnosis of 
GvHD. 
 
Chronic GvHD will be diagnosed and graded according to Sullivan 64 and treated with standard or 
experimental immunosuppressive therapy. 
 
12.4. 
Regimen-related and transplant-related mortality 
 
Regimen related toxicity (RRT) refers to those toxicities that can be attributed directly to the 
preparative regimen (including radiation, chemotherapeutic agents and ATG). 
 
Transplant-related mortality (TRM) includes the RRT and other fatal complications resulting 
from the allogenic transplant such as graft failure, GvHD, hemorrhages, and infections. 
 
Toxicities such as alopecia, mucositis, dehydration, anxiety, infection, anorexia, nausea, 
vomiting, diarrhea, fever, rash, fatigue, sleep disturbance, anemia, leukopenia, 
thrombocytopenia, abnormal serum chemistries, impaired renal function and hepatic function 
occur in almost all patients who receive a myeloablative preparative regimen for transplant and 
are considered expected adverse events. These toxicities will be routinely monitored as part of a 
clinical assessment and reported as adverse events at the PIs discretion. 
 
The grading for monitoring transplant related toxicities will be based on the NCI/CTEP common 
toxicity criteria 4.0. Adverse events/toxicities that will be tracked and collected are Serious 
Adverse Events that are defined in section 17. 
 
12.5. 
Infections. 
 
The occurrence of life-threatening opportunistic infections will be evaluated according to the 
criteria established by BMT CTN and will correlate this with the level of immune recovery. The 
infection-related mortality will be also determined. Patients will be considered to have died from 
infection if death is attributed to a recent severe infection and/or infection was identified at 
autopsy. Patients with relapsed disease before death will be excluded from the above definition, 
even if an infection was the final cause of death. 
 
12.6. 
Disease relapse 
 
Relapse of MDS, AML and AML will be defined by an increasing number of blasts in the marrow 
over 5%, by the presence of circulating peripheral blasts, or by the presence of blasts in any 
extramedullary site. Cytogenetic analysis of the marrow and/or peripheral blood will also be 
obtained for the diagnosis of relapse. 


MEMORIAL SLOAN-KETTERING CANCER CENTER 
IRB PROTOCOL 
IRB#: 12-053A(7) 
Amended:  07/30/15 
Page  37 of 47 
 
 
Relapse of myeloma will be diagnosed by clinical and radiological findings coupled with biopsy of 
affected tissue. A sustained risk in the serum concentration of myeloma paraprotein will also be 
considered evidence of relapse. 
 
12.7. 
Disease-free Survival 
 
DFS is defined as the minimum time interval of times to relapse/recurrence, to death or to the 
last follow-up, from the time of transplant. 
 
 
 
12.8 
Overall Survival 
 
Overall survival is defined as time from transplant to death or last follow-up. 
 
 
 
 
12.9 
CD34+ and CD3+ Cell Doses 
 
Total CD34+ and CD3+ cell doses will be calculated based on results of flow cytometric analysis. 
 
 
 
13.0    CRITERIA FOR REMOVAL FROM STUDY 
 
If at any time the research participant is found to be ineligible for the protocol as designated in 
the section on Criteria for research participant eligibility (e.g. a change in diagnosis), the 
research participant will be removed from the study. Also research participants may be 
removed from the study if requested by the research participant. Management will depend on 
where they are in their treatment course. Such research participants will receive appropriate 
supportive care. 
 
 
 
14.0 
BIOSTATISTICS 
 
A pilot study is developed to provide initial data on the efficacy and safety of a biparental HLA 
haplotype disparate T-cell depleted transplant for patients lacking an HLA-compatible donor. The 
patient population for this study consists of patients transplanted for leukemia, NHL, and MDS, as 
well as lethal, non malignant diseases of hematopoiesis and immunity without an HLA identical or 
9/10 HLA allele matched related or unrelated donor. A maximum of 21 patients will be accrued to the 
study and the accrual period is expected to last 3 years with an additional two years of follow up 
after the accrual has been completed. 
 
At the conclusion of the study, Kaplan-Meier estimates of overall and disease-free survival will be 
computed. Estimated probabilities for the time to treatment related mortality, the time to infectious 
complication, and the time to graft versus host disease will be computed using the cumulative 
incidence function. 
 
Immunologic reconstitution will be summarized by averaging the recorded results across patients at 
each time point. Measures of tolerance and HLA restriction will be assessed using cytotoxicity 
assays. Graphic descriptions of the trajectories over time will be produced using kernel smoothing.

both pediatric and adult accruals. The responsibilities of the RSA and principal investigator 
include project compliance, data collection, abstraction and entry, data reporting, regulatory 
monitoring, problem resolution and prioritization, and coordinate the activities of the protocol 
study team. The data collected for this study will be entered into The Clinical Research Data 
Base (CRDB), a secure database.  Source documentation will be available to support the 
computerized patient record. 
 
16.1 
Quality Assurance 
 
Weekly registration reports will be generated to monitor patient accruals and completeness of 
registration data.  Routine data quality reports will be generated to assess missing data and 
inconsistencies. Accrual rates and extent and accuracy of evaluations and follow-up will be 
monitored periodically throughout the study period and potential problems will be brought to 
the attention of the study team for discussion and action. 
 
Random-sample data quality and protocol compliance audits will be conducted by the study 
team, at a minimum of two times per year, more frequently if indicated. 
 
16.2 
Data and Safety Monitoring 
 
The Data and Safety Monitoring (DSM) Plans at Memorial Sloan-Kettering Cancer Center 
were approved by the National Cancer Institute in September 2001. The plans address the 
new policies set forth by the NCI in the document entitled “Policy of the National Cancer 
Institute for Data and Safety Monitoring of Clinical Trials” which can be found at: 
http://cancertrials.nci.nih.gov/researchers/dsm/index.html. The DSM Plans at MSKCC were 
established and are monitored by the Office of Clinical Research. 
 
There are several different mechanisms by which clinical trials are monitored for data, safety 
and quality. There are institutional processes in place for quality assurance (e.g., protocol 
monitoring, compliance and data verification audits, therapeutic response, and staff 
education on clinical research QA) and departmental procedures for quality control, plus 
there are two institutional committees that are responsible for monitoring the activities of our 
clinical trials programs. The committees: Data and Safety Monitoring Committee (DSMC) for 
Phase I and II clinical trials, and the Data and Safety Monitoring Board (DSMB) for Phase III 
clinical trials, report to the Center’s Research Council and Institutional Review Board. 
 
During the protocol development and review process, each protocol will be assessed for its 
level of risk and degree of monitoring required. Every type of protocol (e.g., NIH sponsored, 
in-house sponsored, industrial sponsored, NCI cooperative group, etc.) Will be addressed

17.0 
PROTECTION OF HUMAN SUBJECTS 
 
The risks associated with a T-cell depleted transplant after cytoreduction by the conditioning 
regimens under study are those associated with the toxicities of the conditioning regimens, 
as detailed in Section 11.0, as well as the risks of an allogeneic transplant, particularly graft 
failure, or graft vs. host disease, as also detailed in Section 11.0. 
 
To protect against the toxicities of the cytoreductive regimens, the patient will be transplanted 
in a single room, HEPA filtered environment. Organ toxicities such as mucositis, enteritis and 
hepatic dysfunction as well as infectious complications will be treated by standard 
procedures developed for transplantation to support our patients.  Blood and platelet counts 
will be supported by transfusion. Graft failure might necessitate a second transplant, after 
additional conditioning. Approaches to the diagnosis and treatment of graft failure that 
secure consistent engraftment have been developed by the Transplantation Services. 
Similarly, advanced treatments will be instituted in the event the patient develops graft vs. 
host disease. 
 
Despite a transplant, the patient’s disease may recur. In this case, standard and/or 
experimental therapies, such as phase I/II drugs, antibodies or cell therapies, will be 
available to the patient for consideration as treatment options. 
 
Benefits: 
 
A transplant is administered with curative intent. The approaches being evaluated may 
achieve this goal and may also be effective in preventing acute and chronic graft vs. host 
disease. 
 
The results of this study will also define risks and benefits of biparental T-cell depleted grafts 
fractionated on the CliniMACS device, when administered after the cytoreduction regimen 
proposed for study. This may greatly accelerate further development of transplantation 
approaches for those who currently cannot be transplanted because of a lack of a suitably 
histocompatible donor. 
 
Consent Process: Participation in this study is voluntary. All patients will be required to sign a 
statement of informed consent which must conform to MSKCC IRB guidelines. 
 
Alternatives:  Enrollment in this study is voluntary. Alternative treatment options will be 
presented to the patient prior to taking part in this study. Alternative treatment options may 
include getting a transplant from a volunteer unrelated donor, if one is available; getting 
treatment for the cancer with either chemotherapy or a transplant without being on a study; 
taking part in another study; or getting no treatment. 
 
Costs: The patient’s health plan/insurance company will need to pay for all of the costs of 
treatment in this study. The patient will be responsible for the costs of standard medical care, 
all hospitalizations and any transplant complications. Pre-authorization for the transplant will 
be cleared with the health plan/insurance company prior to admission. Patients will not be 
paid for taking part in this study. Research tests will be done at no cost to the patient.

17.2.2 Definition of SAEs 
 
A serious adverse event (SAE) is defined as one of the following: 
 
• Is fatal or life-threatening 
• Results in persistent or significant disability/incapacity 
• Constitutes a congenital anomaly/birth defect 
• Is medically significant, i.e., defined as an event that jeopardizes the patient or may require 
medical or surgical intervention to prevent one of the outcomes listed above 
• Requires inpatient hospitalization or prolongation of existing hospitalization, 
• Note that hospitalizations for the following reasons should not be reported as serious 
adverse events: 
o Routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition 
o Elective or pre-planned treatment for a pre-existing condition that is unrelated to 
the indication under study and has not worsened since signing the informed 
consent 
o Social reasons and respite care in the absence of any deterioration in the 
patient’s general condition 
o hospitalizations or prolongation of hospitalizations, due to complications of the 
patient’s previous therapy and/or underlying malignancy 
 
Note that treatment on an emergency outpatient basis that does not result in hospital 
admission and involves an event not fulfilling any of the definitions of a SAE given above is 
not a serious adverse event 
 
Attribution: 
 
 
Unrelated: the AE is clearly NOT related to the intervention 
 
Unlikely: the AE is doubtfully related to the intervention 
 
Possible: the AE may be related to the intervention 
 
Probable: the AE is likely related to the intervention 
 
Definite: the AE is clearly related to the intervention 
 
Expected and Unexpected Event: 
 
 
Expected: Any experience previously reported (in nature, severity, or incidence) in the 
current Investigator’s Brochure or general investigational plan 
 
Unexpected: Any experience not previously reported (in nature, severity, or 
incidence) in the current Investigator’s Brochure or general investigational plan
