1.0      PROTOCOL SUMMARY AND SCHEMA 
 
This is a phase 2 intention-to-treat study of salvage chemotherapy followed by allogeneic 
hematopoietic stem cell transplant (HSCT) for the treatment of primary-refractory or relapsed 
Hodgkin Lymphoma (HL). The primary aim is to obtain a preliminary estimate of the progression- 
free survival at 1 year post-transplant. 
 
Patients aged 13-65 years with primary-refractory or relapsed HL who are suitable allograft 
candidates will be enrolled on the intention-to-treat study prior to salvage chemotherapy. This 
will include patients who fail primary therapy and have all 3 risk factors (B-symptoms; extranodal 
sites of disease; disease remission < one year after first-line therapy), or those who have 2 risk 
factors and remain PET+ after salvage chemotherapy, or those with primary progressive disease, 
or those who have failed platinum-based chemotherapy. In addition, patients who relapse no 
earlier than 100 days after an autologous stem cell transplant will also be included. 
 
Eligible patients will receive 2-3 cycles of second-line combination chemotherapy, using standard 
regimens. Alternatively, patients may also be treated on ongoing MSKCC phase I or II studies 
specific for Hodgkin Lymphoma. 
 
Patients who 1) do not progress on salvage chemotherapy, and 2) have both suitable HSC donors 
and 3) a satisfactory pre-allograft work-up will proceed to allograft. Patients who fail any of these 
3 criteria will be off-study and considered treatment failures for the purposes of the intention–to- 
treat study. 
 
Patients referred with responsive or stable disease after receiving salvage chemotherapy or who 
require more than one second-line combination chemotherapy regimen, will not be included in the 
intention-to-treat analysis of the study but can proceed to allograft on protocol if they are suitable 
candidates. While they will contribute to the allograft outcome data, they will not be part of the 
primary efficacy analysis described below. It is anticipated that approximately 6 patients will be 
treated through this course. 
 
Pre-allograft conditioning and post-graft immune suppression will be determined by remission 
status post salvage chemotherapy assessed at the time of pre-allograft work-up. 
- 
Patients who have stable disease or are in PR will receive a reduced intensity preparative 
regimen of Melphalan and Fludarabine (Mel/Flu). 
- 
Patients in CR will receive a non-myeloablative preparative regimen of Cyclophosphamide, 
Fludarabine and low dose total body irradiation (Cy/Flu/TBI). 
 
Hodgkin’s relapse or disease progression will be defined using CT and PET criteria. Complete 
remission is defined as resolution of all disease related symptoms and normalization of PET scan 
and of bone marrow involvement on morphologic exam. Partial remission (PR) is ≥ 50% decrease 
in the sum of product of diameters (SPD) of the 6 largest dominant lymph nodes and of sites of 
organ involvement, no increase in size or number of involved lymph nodes or organs, decrease in 
PET avidity. Stable disease (SD) is less than PR but is not progressive disease. Progressive/ 
relapsed disease (PD) is appearance of a new lesion ≥50% increase in SPD of more than one node 
or in greatest diameter of any previously identified node >1 cm in its short axis.

Cytoreduction will be followed by transplantation using the best available donor according to the 
BMT Service donor algorithm (sibling or unrelated donor (URD) peripheral blood stem cells 
(PBSC), or bone marrow (BM), or umbilical cord blood (UCB)). Immune suppression will be with 
Tacrolimus, Sirolimus and Methotrexate for related or unrelated donors, and cyclosporine-A 
(CSA) and mycophenolate mofetil (MMF) for UCB. In the absence of GVHD, withdrawal of 
immune suppression in patients who proceed to allograft with less than a PR will be done more 
rapidly than in patients in PR or CR (off by 120 days instead of 6 months). Patients with 
progression of disease (POD) prior to allograft will not undergo allo-HSCT. 
 
Patients will be carefully monitored for toxicity from the salvage chemotherapy, and post-allograft 
for donor engraftment and count recovery, donor chimerism, the incidence and severity of acute 
and chronic graft-versus-host disease (GVHD), transplant-related mortality (TRM), characteristics 
of immune recovery, as well as overall and progression-free survival. 
 
Biostatistics will be based on a sample size of 30 patients (24 on ITT study, and 6 transplanted 
without salvage therapy administered on protocol) and it is anticipated that approximately 24 of 
these patients will proceed to allograft. The accrual period will be approximately 4-5 years with a 
follow-up period of 2 years post-transplant. 
 
For this study, a patient will be classified as a success, if he or she responds due to salvage 
chemotherapy, undergoes an allogeneic HSCT, and remains progression free for one year after 
HSCT. Currently, 5 of 15 patients are recorded a success on this study. These 15 patients are 
incorporated into a Simon two-stage minimax design that differentiates between success rates of 
0.20 and 0.45. In the first stage, since more than 3 successes out of 15 patients were observed, an 
additional 9 patients will be accrued for a total of 24 patients. The salvage chemotherapy followed 
by HSCT would be considered worthy of further study in this patient population if 8 or more 
successes from the 24 patients were observed. This two-stage design has power 0.90 if the 
population success proportion is 0.45 and has a type 1 error equal to 0.10 at the success probability 
0.20.

2.1 
OBJECTIVES AND SCIENTIFIC AIMS 
2.2 Primary Objectives 
 
Patients with Hodgkin Lymphoma (HL) relapsed post-autograft are not able to be cured with 
standard chemotherapy regimens. In addition, a subset of relapsed and primary-refractory 
patients with HL fare poorly with conventional autologous transplant. Such patients may benefit 
from allogeneic transplantation secondary to a graft-versus-malignancy (GVM) effect1-7. This 
protocol investigates an intention-to-treat approach to such patients with salvage chemotherapy 
followed by allogeneic hematopoietic stem cell transplant (HSCT) for the treatment of high- 
risk or relapsed HL. 
 
The primary aim of this study is to obtain a preliminary estimate of the progression-free survival 
at 1 year after allo-HSCT.

3.1 
BACKGROUND AND RATIONALE 
 
3.2 Introduction 
 
The majority of patients with HL are cured with standard chemoradiotherapy approaches. 
However, patients who relapse after attaining a complete remission with chemotherapy and those 
with primary refractory disease have a poor outcome with conventional-dose salvage regimens. 
Over the past 15 years, several clinical trials using high dose chemotherapy or chemoradiotherapy 
with autologous stem cell transplantation (ASCT) in this setting have been reported, and 
approximately 40% of patients appear to be cured using this approach.8 Two randomized studies 
comparing standard-dose second-line chemotherapy with high dose therapy (HDT) and ASCT 
have been reported.9,10 Each study demonstrated a statistically significant improvement in both 
event-free and progression free survival for the patients treated on the HDT arms, but neither was 
powered to show an overall survival advantage. Despite the success with HDT/ASCT, more than 
50% of patients fail this approach; median survival of these patients is 15 months. 
3.3 Chemosensitive disease is required to achieve benefit from HDT/ASCT 
 
The importance of pre-transplant cytoreduction with salvage therapy (ST) has been demonstrated 
in numerous series. In 1991, we reported our results using high dose combined modality therapy 
in patients with biopsy-confirmed relapsed and primary refractory HL in our first generation 
programs (MSKCC protocols 85-97 and 86-86). The program utilized accelerated fractionation 
radiotherapy either as total lymphoid irradiation (TLI) or as an involved field (IFRT) followed by 
high dose chemotherapy and bone marrow infusion. One hundred and fifty-six patients were 
treated; chemosensitive disease was not a requirement for transplantation however patients were 
given non-uniform second-line standard dose chemotherapy with the hope of debulking disease 
pre-ASCT. At a median follow-up of 11 years the EFS is 45% with no relapses occurring later 
than 36 months post-ASCT. After the introduction of G-CSF, 100 day mortality decreased form 
18% to 6%.11,12 These results demonstrated the feasibility of incorporating dose intensive 
radiotherapy into HDT for HL and most importantly the study determined that patients with 
chemosensitive disease to ST pre-HDT/ASCT have a marked improvement in EFS compared to 
patients with refractory disease at the time of HDT. As with aggressive non-Hodgkin’s lymphoma, 
chemosensitive disease to ST is now required for transplant eligibility in the United States. 
 
3.4 ICE chemotherapy is a highly effective standard-dose second-line regimen in HL

In 2001 we reported the results of a comprehensive program for 82 patients with relapsed and 
refractory HL (MSKCC 94-68/97-51).13 All patients received uniform cytoreduction with 
ifosfamide, carboplatin and etoposide (ICE) and only responders were subsequently offered HDT 
and ASCT. All patients in this trial had biopsy-proven relapsed or refractory disease, and our data 
were analyzed by intent-to-treat. The Kaplan-Meier estimate of the proportion of patients who are 
alive, event-free and analyzed by an intent-to-treat at a median follow-up for surviving patients of 
six years is 55%. In the subset of patients who received HDT/ASCT (75 of 82 patients), the EFS 
is 61%. The response rate to ICE was 85% and only 12% of patients had an inadequate peripheral 
blood progenitor cell (PBPC) harvest. In addition, integrating higher dose chemotherapy into the 
transplant conditioning regimen was safe; with a 100 day mortality of 2.6%. These results compare 
very favorably with reports in the literature. Our program documents the feasibility and efficacy 
of: (1) ICE chemotherapy as a highly effective dose dense/intense cytoreductive regimen in HL 
and (2) integrating higher dose radiotherapy into an ASCT treatment program. 
 
3.5 A three-factor model predicts outcome in relapsed and primary refractory HL 
 
Response to second-line chemotherapy has been used as the major selection criteria to proceed to 
ASCT, but other prognostic factors may also predict for long-term EFS in patients with relapsed 
and refractory HL. In MSKCC protocol 94-68, Cox regression analysis determined that the factors 
associated with a poor outcome pre-ICE chemotherapy were: extranodal sites of disease (ENS), p 
<0.001, initial response duration < 1 year (p = 0.001), and B symptoms (p <0.001). Using this 3 
factor model we identified 3 groups of patients with widely disparate outcome with this treatment 
approach. The largest group, 65% of the total number of patients had 0-1 of these risk factors. 
This favorable group had an EFS of 80% measured from initiation of ICE therapy. Patients with 
2 and 3 risk factors fared less well with an EFS of 34% and 12% respectively. 
 
3.6 Risk-Adapted therapy 
 
Risk-adapted therapy can improve EFS in patients with relapsed and refractory HL. This 3 factor 
model was the basis of our recent risk-adapted comprehensive study (MSKCC protocol 98-71). 
The expectation from risk-adapted therapy is a reduction in the influence of risk factor (RF) on 
outcome by improving the results of patients in the less favorable groups. Our strategy was to 
intensify therapy without increasing toxicity for unfavorable patients with multiple risk factors, 
while at the same time, maintaining the previous regimen used successfully for the favorable 
cohort. The primary endpoint of this study was to improve outcome by diminishing the 
significance of the three factor prognostic model with tailored therapy. In this study of 105 
patients, the median follow-up of the patients is now 4.5 years and patients with multiple RF have 
an improved EFS as compared to our previous results. Patients with 0 or 1 risk factor (ENS, initial 
response duration < 1 year or B symptoms at time of study enrollment), group A, were treated 
exactly as those on the 1994 -1998 program. The outcomes of the favorable patients between the 
two studies is similar, hence we prospectively confirmed the results in good risk patients. Patients 
with 2 RF have a 3-year EFS of 46% (95% CI: 31%-62%); the 3-year EFS from the previous study 
was 27%. The 3-year EFS for patients with 3 factors is 46% (95% CI: 20%-71%); the 3-year EFS 
was 10% in our previous study. This improved EFS in patients with 3 RF was obtained after 
tandem ASCT, an approach that is considered investigational at the present time.

IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022

Despite an 85% response rate to ST, 35% of patients with 0-2 RF will die of their disease. The 
incorporation of non-cross resistant chemotherapy regimens that include gemcitabine and IMRT 
to further cytoreduce disease burden prior to HDT, in an attempt to improve EFS, is reasonable 
and is the basis of our current study MSKCC protocol 04-047, which excludes patients with all 3 
risk factors. 
 
3.7 Abnormal Functional imaging pre-ASCT predicts a poorer outcome in patients with 
chemosensitive disease 
 
Our prognostic model is based upon pretreatment factors; however, since almost all patients have 
cytoreduction to “ICE” chemotherapy, other factors, evaluated at the time of HDT, may be 
important. Reports by other groups have shown that tumor bulk of < 5 cm or being in a complete 
response pre-ASCT portended an improved survival. We evaluated both of these factors in our 2 
studies (94-68 and 98-71) and they did not predict outcome. Patients with HL commonly have 
large residual masses secondary to underlying sclerosis of the tumor and only a minority of patients 
achieves a true CR pre-ASCT. However all of our patients have functional imaging, PET or 
gallium scanning, pre and post ICE and we evaluated the effect of normalization of functional 
imaging pre-ASCT on outcome. There was a marked survival advantage for patients who 
normalize their functional imaging (FI) pre-ASCT. For all transplanted patients the EFS is 64.3% 
however the patients with normal FI have an EFS of 76% vs 40% for patients with abnormal 
imaging (p <0.0001). This was most important for patients with favorable risk factors, ARM A, 
where the EFS is 85% for patients with normal FI vs 25 % for patients with abnormal FI, p < 
0.0001. Despite the more dose intense regimens used in patients with 2 or 3 risk factors in protocol 
98-71, patients with abnormal functional imaging pre-ASCT had a very poor outcome. 
 
3.8 Gemcitabine-based therapy in HL 
 
Treatment for HL patients who fail ASCT is palliative with no standard. We retrospectively 
evaluated our experience with two active agents, gemcitabine (G) and vinorelbine (N, Navelbine), 
given in combination for patients who fail ASCT. Thirteen patients received GN, median age 33 
(range 23-46). Patients had progressed following ASCT (median 7.4 months; range 2.9-51) and 
had received 3-7+ prior cytotoxic regimens. The median number of treatments for responding 
patients was 11 (range 5-47); median follow-up for surviving patients is 17.5 months. 9/13 patients 
(69%) responded or had stable disease. The median freedom-from-progression (FFP) and OS for 
all patients was 7.4 months (95% CI 0.7, 14.1) and 30.4 months (95% CI 5.5, 55). Gemcitabine 
(G), vinorelbine (N, Navelbine), and liposomal doxorubicin (D) have been studied by the CALGB 
Between 7/15/00 and 12/9/02. Seventy-six patients with recurrent or refractory HL were accrued 
to this CALGB Phase I/II trial of GND. The objectives were to determine the maximal tolerated 
dose (MTD), response rates, and toxicity of this combination. All patients had measurable disease, 
no prior treatment with these agents, ANC > 1500 and platelets >100,000. Any number of prior 
therapies was allowed. 28 patients had prior ASCT. Results: The Phase I portion of the study 
identified G 1000 mg/m2 d1, 8, N 20 mg/m2 D1, 8, and D 15 mg/m2 D1, 8 Q21 days as the MTD. 
Febrile neutropenia and mucositis were the dose-limiting toxicities. A planned interim analysis of 
the Phase II portion of the study showed overall response rates of 58% (95% exact CI [0.34, 0.80]) 
for the first 19 patients without prior transplant (8 PR, 3 CR) and 68% (95% exact CI [0.44, 0.87]) 
for the 19 patients with prior transplant (12 PR, 1 CR). Complete toxicity data is available for 23

of the 38 interim analysis patients. The regimen was well tolerated. Grade 3-4 toxicities included 
neutropenia (69%), thrombocytopenia (17%), febrile neutropenia (9%), mucositis (9%), and 
pulmonary (17%). There were no treatment related deaths. They concluded that GND is an active, 
well-tolerated, non-alkylator based regimen that should be considered both in the pre-transplant 
salvage setting as well as for patients relapsing after transplant. 
 
Gemcitabine has also been combined with ifosfamide and vinorelbine (IGV) in patients with 
relapsed/refractory HL.14,15 This regimen has been well-tolerated and has been used pre-ASCT. 
In a recent report, 32 patients were treated with salvage chemotherapy (IGEV, ifosfamide, 
gemcitabine, and vinorelbine), followed by a tandem ASCT (melphalan 200 mg/m2, BEAM). In 
an intention-to-treat analysis, the overall response rate increased after each stage of protocol, 
ranging from 47% to 65% and 75% after IGEV, MEL200, and BEAM, respectively.14 
 
3.9 Clinical Results of Allotransplant in HL 
 
An alternative treatment strategy for poor risk patients (pts with all 3 risk factors) would require 
investigators not to offer HDT and ASCT to this subgroup but instead, a non-myeloablative 
allogeneic transplantation after some cytoreduction with ST. Recent evidence from several groups 
suggests that here is evidence of a graft vs. HL effect after non-myeloablative allogeneic 
transplantation1. 
 
3.9.1 Clinical Results with Sibling and Unrelated Donor HSCT 
 
Initial studies of allo-HSCT demonstrated high TRM and low OS, likely due to the use of 
myeloablative regimens in heavily pre-treated patients.16-20 More recent studies in which patients 
underwent reduced-intensity or non-ablative cytoreduction have shown improved outcomes and 
decreased TRM.21-24 Peggs et al.21 recently reported the results of reduced-intensity 
transplantation in 49 patients with multiply relapsed Hodgkin's lymphoma, 90% of whom had 
progression of disease after previous ASCT. Non-relapse-related mortality was 16.3% at 730 days 
(7.2% for patients who had related donors vs 34.1% for those with unrelated donors, p=0.0206). 
Projected 4 year overall and progression-free survival were 55.7% and 39.0%, respectively (62.0% 
and 41.5% for related donors). Eight of 49 (16%) had grade II-IV acute GVHD and seven (14%) 
had chronic GVHD before donor-lymphocyte infusion. Sixteen patients received donor- 
lymphocyte infusion from 3 months after transplantation for residual disease or progression and 9 
showed disease responses after infusion (CR=8, PR=1). The patients enrolled on this clinical trial 
did not receive a true non-ablative regimen, but instead, a reduced intensity conditioning regimen 
that included 140 mg/m2 of melphalan. There is little doubt that this dose of melphalan is active 
in the treatment of HL. Investigators from MD Anderson have reported similar results with this 
approach.23 
 
3.9.2 Clinical Results of Non-myeloablative UCBT: Overall and in HL 
 
Results of unrelated donor UCBT have demonstrated that banked UCB is rapidly available25 and 
can successfully engraft the majority of small children with a relatively low incidence of acute and 
chronic GVHD despite HLA disparity.26 However, adult UCBT is limited by the low infused cell 
dose.26-28   Therefore, for larger adolescents and adult patients undergoing UCBT, efforts must be

focused on improving engraftment and decreasing TRM. To address this problem the University 
of Minnesota has investigated the novel approach of the combined transplantation of two UCB 
units in a double unit graft after myeloablative conditioning as a strategy to augment graft cell 
dose.29 These studies have shown that double unit UCBT can be performed safely in adults with 
improved engraftment and reduced TRM as compared to historical single unit controls. This 
strategy therefore extends access to allogeneic transplantation and introduces adult UCBT as a 
viable alternative to both matched and mismatched marrow transplantation. Further, given the 
relatively small cell dose of the engrafting unit, these results raise intriguing questions concerning 
the transplant biology of this approach. Therefore, further investigation of double unit UCBT is 
warranted. 
 
The University of Minnesota has also investigated non-myeloablative UCBT, utilizing double unit 
grafts in those without satisfactory single units, to augment graft cell dose, in 59 high-risk adults 
(median age 49 years) with high-risk or advanced hematologic malignancies.30. Patients received 
cyclophosphamide 50 mg/kg, fludarabine 200 mg/m2, and 200 cGy TBI (+ anti-thymocyte 
globulin), with cyclosporine-A and mycophenolate mofetil, and either single (n = 14) or double (n 
= 45) 4-6/6 HLA-matched UCB units with a median total infused dose of 3.4 x 107 NC/kg. 
Neutrophil recovery occurred at a median of 8 days (range 5-32). The cumulative incidence of 
sustained donor engraftment was 89% (95%CI: 81-97) overall, and 98% (95%CI: 94-100) in 
patients with a prior autograft or combination chemotherapy within the prior 3 months. The 
cumulative incidence of grade II-IV acute GVHD was 63% (95%CI: 49-77) at day 100, and 
chronic GVHD was 28% (95%CI: 16-40) at 1 year, with a TRM of 19% (95%CI: 9-29) at day 180. 
Notably, TRM was 14% in patients > 45 years, 24% in patients with extensive prior therapy, and 
44% in patients with significant co-morbidities. Cox regression analysis revealed that the relative 
risk of TRM by day 180 was 0.8 (0.2-3.2; p = 0.78), 1.5 (0.4-5.6; p = 0.56) and 8.0 (2.0-32.0; p < 
0.01) in these 3 patient groups, respectively. With a median follow-up of 16 months (range 4-30), 
the probability of overall and progression-free survival was 44% (95%CI: 30-58) and 35% 
(95%CI: 21-49) at 2 years. Therefore, non-myeloablative UCBT is associated with prompt 
neutrophil recovery, a high incidence of sustained engraftment and relatively low TRM in older or 
extensively pre-treated adults provided they have satisfactory fitness and reasonable progression- 
free survival in this high-risk patient population. 
 
The same group also recently reported on their experience in 9 patients with HL.31 All patients 
sustained donor engraftment by day 60. Cumulative incidence of acute and chronic GVHD were 
33% and 11%, respectively. TRM at 100 days was 11% and the 2 year PFS was 25% (95%CI: 0- 
55%). This approach will be investigated specifically in the treatment of HL in this protocol. 
 
3.10 Summary 
 
Although initial studies of allogeneic transplantation with myeloablative conditioning regimens 
were associated with poor outcomes due to high TRM in patients with HL, more recent studies 
with reduced intensity regimens have shown promising results. A number of lessons can be 
learned from our prior experience in the treatment of patients with relapsed and primary refractory 
HL: 
1) 50% of these patients can be cured with HDT/ASCT; 
2) Chemosensitive disease is required to achieve benefit from HDT/ASCT;

3) A 3 factor model that includes extranodal sites of disease (ENS), initial response duration 
< 1 year, and B symptoms predicts outcome in relapsed and primary refractory HL treated 
with HDT/ASCT; 
4) Risk-adapted therapy can improve EFS in patients with relapsed and refractory HL; 
5) PET scanning should be used to determine response and eligibility for transplant; 
6) Recent evidence from several groups suggests that there is evidence of a graft vs. HL effect 
after non-myeloablative allogeneic transplantation. 
Several important questions remain to be answered, including patient selection for ASCT vs. Allo- 
HSCT based on risk factors, timing of allo-HSCT, as well as the intensity of the conditioning 
regimen. Finally, most allo-HSCT studies report data of the transplant alone, but do not report the 
percentage of patients are actually able to undergo allo-HSCT for advanced lymphoma or 
leukemia.  The goal of this protocol is to address these important questions. 
 
4.1 
OVERVIEW OF STUDY DESIGN/INTERVENTION 
 
4.2 
Design 
 
This is a phase 2 intention-to-treat study of salvage chemotherapy followed by allogeneic HSC 
transplant for the treatment of primary refractory or relapsed HL. The primary aim is to obtain a 
preliminary estimate of the progression-free survival at 1 year post-transplant. 
 
Patients aged 13-65 years with primary-refractory or relapsed HL who are suitable allograft 
candidates will be enrolled on the intention-to-treat study prior to salvage chemotherapy. This will 
include patients who fail primary therapy and have all 3 risk factors (B-symptoms; extranodal sites 
of disease; disease remission < one year after first-line therapy), or have 2 risk factors and remain 
PET+ after salvage chemotherapy, or those with primary progressive disease, or those who have 
failed platinum-based chemotherapy. In addition, patients who relapse no earlier than 100 days 
after an autologous stem cell transplant will also be included. 
 
Patients referred with responsive or stable disease after receiving salvage chemotherapy or who 
require more than one second-line chemotherapy regimen, will not be included in the intention-to- 
treat analysis of the study but can proceed to allograft on protocol if they are suitable candidates. 
While they will contribute to the allograft outcome data, they will not be part of the primary 
efficacy analysis described below. 
 
4.3 Intervention 
 
Eligible patients will receive 2-3 cycles of second-line combination chemotherapy, using standard 
regimens. Alternatively, patients may also be treated on ongoing MSKCC phase I or II studies 
specific for Hodgkin Lymphoma. 
 
Pre-allograft conditioning and post-graft immune suppression will be determined by remission 
status post salvage chemotherapy assessed at the time of pre-allograft work-up. 
 
Patients who have stable disease or are in PR will receive a reduced intensity preparative regimen 
of Melphalan and Fludarabine (Mel/Flu). 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 11 - 
 
 
 
 
Patients in CR will receive a non-myeloablative preparative regimen of Cyclophosphamide, 
Fludarabine and low dose total body irradiation (Cy/Flu/TBI). 
 
Cytoreduction will be followed by transplantation using the best available donor (sibling or 
unrelated donor (URD) peripheral blood stem cells (PBSC), or bone marrow (BM), or umbilical 
cord blood (UCB)). Immune suppression will be with Tacrolimus, Sirolimus and Methotrexate for 
related or unrelated donors, and cyclosporine-A (CSA) and mycophenolate mofetil (MMF) for 
UCB. In the absence of GVHD, withdrawal of immune suppression in patients who proceed to 
allograft with less than a PR will be done more rapidly than in patients in PR or CR. Patients with 
progression of disease (POD) prior to allograft will not undergo allo-HSCT.

7.0      RECRUITMENT PLAN 
 
Patients who fulfill the eligibility criteria as listed in Section 6.0 will be recruited for this study by 
an Attending Physician of the Lymphoma or BMT Service. Informed consent will be obtained by 
one of the participating investigators authorized to obtain consent. A copy of the signed informed 
consent will be placed in the medical record, as well as in the research file. Confirmation of patient 
eligibility will be done via the Clinical Trials Office. 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 16 - 
 
 
 
 
 
 
Eligibility for the protocol should be determined by consultation with the physicians of the 
Lymphoma Service and the physicians of the Bone Marrow Transplant Service. For inclusion in 
the intention-to-treat component of the study, patients will be evaluated prior to salvage 
chemotherapy. The Lymphoma Service Physicians will decide upon the appropriate salvage 
chemotherapy, ensure the patient is an appropriate candidate for subsequent potential allograft, 
and contact the BMT service to initiate the donor search. Patients will then sign consent part I: 
Intention-to-Treat and proceed with salvage chemotherapy. 
 
A suitable HSC graft will be secured during salvage chemotherapy. Once the graft is secured and 
salvage is complete, pre-allograft work-up and disease re-staging will be performed by the BMT 
Service as an outpatient. Eligible patients will be consented for allograft by the BMT service 
(consent part II) and then admitted to the Bone Marrow Transplant Unit for HSCT. 
 
For the purposes of study enrollment complete remission (CR) will be defined as outlined in 
Section 12.5 whereas partial remission (PR) will be defined as > 50% reduction of disease based 
on CT or PET criteria. Stable disease (SD) will be defined as absence of progression or < 50% 
reduction of disease based on CT or PET criteria. If there is a conflict between CT and PET 
responses, the PET scan will be used to define responses. 
 
This protocol will take due notice of NIH/ADAMHA policies concerning inclusion of women and 
minorities in clinical research populations. We expect that the study population will be fully 
representative of the range of patients referred for transplant without exclusion as to age, gender, 
or ethnic background within the limits of being able to identify a suitable HSCT graft. Pregnant 
women are excluded from participation in this study.

Adults: Sirolimus will be given in a loading dose of 12 mg orally on Day –3 followed by a daily 
oral dose of 4 mg per day. Doses may be repeated if the subject vomits within 15 minutes of an 
oral dose. 
 
Children: Children weighing < 40.0 kg will be given an oral loading dose of sirolimus of 3 mg/m2 
followed by a daily oral dose of 1 mg/m2, rounded to the nearest full milligram. 
 
Adults and Children: Tacrolimus will be given at a dose of 0.02 mg/kg every 24 hours as a 
continuous intravenous infusion beginning on Day –3. Convert the tacrolimus to oral dosing at 2- 
3 times the total 24-hour intravenous dose, split into 2 doses given every 12 hours as soon as 
clinically feasible. 
 
 
Methotrexate will be given at a dose of 5 mg/m2 intravenously on days +1, +3 and +6 to recipients 
of related or unrelated donors. The day +1 dose should not be administered until 24 hours after the 
BM or PBSC infusion. All doses of methotrexate should be administered unless life-threatening 
complications prevent administration. The BMT attending will determine if any MTX dose 
adjustments are necessary. IV folinic acid is NOT given after mini-methotrexate. 
 
Methotrexate dose adjustment will be as follows: 
 
HOLD: for Creatinine that doubles from admission AND is >2.0 mg/dl OR Creatinine >3.0 mg/dl 
(regardless of baseline Creatinine). 
 
HOLD: for total Bilirubin > 3.0 mg/dl

MTX DOSE ADJUSTMENTS FOR WEIGHT: Use actual body weight for patients with BSA < 
2.5 m2, and adjusted body weigth for BSA > 2.5 m2. 
 
IMMUNESUPPRESSION WHEN MTX IS HELD: If a dose MTX is not given, another immune 
suppressant such as MMF 1gm IV q8 hours must be instituted. 
 
 
Target serum levels and dose modifications 
 
The target serum level for sirolimus is 3-12 ng/mL. 
 
Dose adjustments are based on clinical judgment of the treating physician after considering clinical 
toxicity, serum levels, GVHD, concomitant drug use and the rate of rise or decline of the serum 
level. For levels < 3 ng/mL, unless clinically contra-indicated, the dose of sirolimus is to be 
increased by approximately 25% increments no more frequently than every 2 days, rounded to the 
nearest full milligram until the target range is achieved. Conversely, for levels > 12 ng/mL, it is 
suggested, but not required, that the dose be decreased by approximately 25% no more frequently 
than every 2 days until the target level is achieved. Alternatively, sirolimus can be held entirely 
as long as serum levels are monitored and the drug is restarted when the level returns to the 
therapeutic range and the treating physician feels it is appropriate to restart the agent. In patients 
where therapeutic levels cannot be achieved or maintained, alternative immunosuppressive drugs 
should be substituted. 
 
The target serum level for tacrolimus is 5-10 ng/mL. 
 
Dose adjustments are based on clinical judgment of the treating physician after considering clinical 
toxicity, serum levels, GVHD, concomitant drug use and the rate of rise or decline of the serum 
level. For levels < 5 ng/mL, the dose of tacrolimus will be increased by approximately 25% 
increments every 1-2 days, rounded to the nearest 0.5 mg (when dosing is oral) until the target 
range is achieved. Conversely, for levels > 10 ng/mL, the dose of tacrolimus will be decreased by 
approximately 25% every 1-2 days until the target level is achieved. Alternatively, tacrolimus can 
be held entirely as long as serum levels are monitored and the drug is restarted when the level 
returns to the therapeutic range and the treating physician feels it is appropriate to restart the agent. 
 
Tapering 
 
Tapering of sirolimus and tacrolimus will begin at Day 60 in the absence of GVHD and disease 
relapse. The goal of tapering is the complete discontinuation of immunosuppressant medications 
by 6 months or earlier if patients are in CR at transplant work-up (see below). Sirolimus and 
tacrolimus should be tapered in an alternating fashion every other week when clinically feasible. 
Similar reductions in dosages should be employed for each drug at each tapering event, with 
modifications at the end of the tapering schedule to allow near simultaneous discontinuation of 
sirolimus and tacrolimus.

Transplant 
 
Patients will receive GVHD prophylaxis with 2 drugs as follows: 
 
• Cyclosporine A (CSA) beginning on day -3 maintaining a level of 200-400 mg/L. The 
initial dose will be 2.5 mg/kg IV every 12 hours, over 2-4 hours as per MSKCC guidelines. 
• Dose adjustments should be made on the basis of toxicity and low CSA levels with a trough 
level of < 200 mg/L. 
• Once the patient can tolerate oral medications and has a normal gastro-intestinal transit 
time, CSA can be converted to an oral form. 
• Patients will receive CSA for approximately 6 months. If no history or suspicion of 
GVHD, the dose should then be tapered with monitoring for development of GVHD and 
aiming to be off immunosuppression by 9-12 months after transplant if possible. 
• Patients intolerant of CSA due to renal impairment or other toxicity aim for a lower level 
if possible. This can be done at the discretion of the treating physician. If unable to tolerate 
they may require tapering of CSA before MMF. 
• Patients unable to tolerate CSA due to renal impairment or other toxicity should be 
considered for an alternative immunosuppressant in addition to mycophenolate mofetil as 
per MSKCC guidelines. 
• In case of major CSA toxicity (eg CNS neurotoxicity documented by MRI), CSA should 
be discontinued. Patients may be re-challenged at a later date if clinically appropriate. 
• For patients with GVHD, CSA may be continued for longer time periods according to 
standard of care guidelines. 
• If disease progression or persistence occurs, or the patient is considered to be at very high 
risk of relapse, early taper or cessation of CSA can be considered with close observation 
for GVHD. 
 
• Mycophenolate mofetil (MMF) should begin on day –3 at a dose of 1 gram IV q8 hours 
for patients who are > 50 kg.  For patients < 50 kg, give 15 mg/kg IV q8 hours. 
• MMF from day -3 to hospital discharge (must be at least day +14) should be IV. In 
preparation for discharge, switch to oral route (CellCept or generic mycophenolate mofetil, 
same dosing as IV) and round to tablet size. 
• No dose adjustments for renal or liver disease are needed routinely unless severe organ 
dysfunction. 
• Measurements of serum blood levels of MMF should be done routinely as per current 
MSKCC guidelines to guide assessment of potential MMF toxicity in the event of 
unexpected myelosuppression. 
• If patient > +28 days and without neutrophil engraftment, consideration can be made to 
reduce dosing to q12 after discussion with PI or co-PI. See MSKCC guidelines for further 
information about MMF levels.

• If no suspicion of GVHD, MMF can be tapered at approximately 75-100 days post- 
transplant. Keep the q8 dosing and taper at 10-25% decrements. The aim to be off the drug 
by approximately 4-6 months. 
• Patients who are intolerant of MMF due to myelosuppression may require earlier but slow 
taper at the treating physician’s discretion. Do not abruptly stop the drug unless life- 
threatening toxicity is suspected. 
• If the patient is intolerant of CSA, MMF taper may be delayed. 
• If the patient has acute GVHD requiring systemic therapy, MMF should only be tapered if 
control of GVHD has been obtained (eg resolution of skin rash, vomiting, and diarrhea), 
unless significant toxicity is attributed to MMF. 
• If disease progression or persistence occurs, or the patient is considered to be at very high 
risk of relapse, early taper or cessation of MMF can be considered with close observation 
for GVHD. 
 
For all patients (RD, URD, UCB) 
 
For patients with GVHD, immunosuppression may be continued for longer time periods according 
to clinical care guidelines. 
 
In patients not in CR prior to transplant, or if disease progression occurs, early taper or cessation 
of immunosuppression can be considered with close observation for GVHD. 
 
 
 
9.7 Infusion of Sibling and Unrelated Volunteer Grafts 
 
Beginning 5-6 days before the day of transplant, the normal donor will receive 10 mcg/kg of G- 
CSF, administered subcutaneously daily for at least 5 days. On the fifth and sixth days, the donor 
will undergo daily leukapheresis designed to provide 109 mononuclear cells per kilogram of 
recipient body weight. Mononuclear cell fractions will be pooled as collected, and will be assayed 
for CD34+ cell enumeration per standard procedures. The targeted dose of CD34+ donor PBPC to 
be infused is at least 5x106 cells/kg. 
 
If donor and recipient are ABO incompatible, appropriate red blood cell and/or plasma depletion 
will be performed. Thereafter, collected donor PBPC will be transfused by slow IV infusion, after 
suitable premedication as appropriate. Vital signs are to be obtained and documented before and 
after the infusions, and monitored during infusions as appropriate. 
 
9.8 UCB Thaw and Administration 
 
• UCB grafts will be received at the MSKCC Cytotherapy Laboratory prior to the start of 
the preparative regimen. 
• Units will be thawed by and released from the Cytotherapy Laboratory according to current 
standards of practice (SOPs) and release criteria. As per standard practice, ABO blood 
group, total nucleated cells (TNC), CD34+ and CD3+ cell number and viability, sterility 
and colony-forming units (CFU) will be measured post-thaw. 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 24 - 
 
 
 
 
• Units should be administered immediately upon arrival to the patient care unit by IV 
infusion by the nursing staff under supervision of a BMT attending physician. UCB 
infusion nursing guidelines should be followed. 
• Units should be given consecutively as per nursing guidelines. 
• Pre-medication should include acetaminophen and diphenhydramine or hydroxyzine dosed 
as appropriate for patient age. Do not give Hydrocortisone. Anti-emetics may be necessary 
and can be given prn. 
• IV hydration equal to twice standard maintenance should be given for 6 hours prior to and 
at least 12 hours post UCB graft infusion with close monitoring of fluid balance, per 
MSKCC guidelines. 
• IV Hydralazine should be used to treat hypertension associated with UCB infusion, if 
necessary. 
 
Following infusion the bag and tubing from each UCB unit must be submitted to the Microbiology 
Laboratory. Specimen for Diagnostic Molecular Pathology will be forwarded by the personnel in 
the Cytotherapy Laboratory. 
 
 
 
 
 
 
9.9 Growth Factor (G-CSF) after HSCT 
 
G-CSF 5 mcg/kg/day IV/SQ (rounded to vial size to maximum of 480 mcg) will be given to all 
patients as from day +7 if absolute neutrophil count (ANC) is < 500. Continue until ANC is >2000 
for 3 consecutive days. GCSF may be given earlier post transplant if clinically indicated at the 
discretion of the Attending Physician. 
 
10.1 EVALUATION DURING TREATMENT/INTERVENTION 
 
10.2 Second line chemotherapy 
 
Eligible patients will receive 2-3 cycles of combination chemotherapy as described in section 9.1. 
Following completion of chemotherapy and prior to allogeneic HSCT, patients may receive IFRT

The remainder of this section applies to patients undergoing allogeneic HSCT. 
 
10.3 Prophylaxis against Infection 
 
Patients will be treated according to the allogeneic BMT standard of care guidelines and will be 
given prophylaxis against 1) bacteria during neutropenia, 2) Pneumocystis carinii, 3) Herpes 
simplex and Herpes Zoster, and CMV if recipient seropositive and 4) fungal infections. Patients 
who are Cytomegalovirus (CMV) seronegative pre-transplant should receive CMV seronegative 
blood products, except in an emergency. Patients will be closely monitored for activation of CMV 
and CMV viremia will be treated according to the allo BMT guidelines with ganciclovir or 
foscarnet. 
 
10.3 Transfusions 
 
All blood products for transfusion, with the exception of the stem cell graft, will be irradiated to 
3,000 cGy to inactivate lymphocytes capable of initiating transfusion associated GVHD. Blood 
products are irradiated in the blood bank, using a cesium gamma emitter. Patients who are CMV- 
seronegative pre-transplant should not receive any CMV-seropositive blood products, except in an 
emergency. Platelets will be administered for clinical evidence of active hemorrhage and 
prophylactically in order to maintain a platelet count greater than 20,000. Packed irradiated red 
blood cells will be administered as clinically indicated. 
 
10.4 Prophylaxis Against Menstrual Bleeding 
 
Post-pubertal females will receive hormonal therapy to suppress menses unless a specific contra- 
indication to estrogen exists. This therapy may include Ovral™ (Ethinyl estradiol + norgestrel) 
daily at a dose of one daily tablet orally, estrogen patch +/- oral progesterone, or another regimen 
which has been successful for the patient. Hormonal suppression will continue until the platelet 
count is at least 50,000. 
 
10.5 Nutritional Support 
 
The physician will monitor nutritional status, and high-calorie parenteral alimentation will be 
given as needed. Vitamin supplements will be administered as clinically indicated. 
 
10.6 Correlative Studies on UCB Units 
 
Laboratory research studies will be performed using a maximum of 5% of each unit on the day of 
thaw investigating the determinants of (or factors associated with) unit predominance in patient 
engraftment. The correlative studies will include: 
 
• Comprehensive characterization of the composition of each unit by flow cytometry (Clinical 
Laboratory, Supervisor Katherine Smith). This will include a basic analysis for CD34+, T, B, 
Disease evaluation (CT 
Scan, PET Scan) 
Following 2nd or 3rd cycle

NK cells (which is a standard of care and billable). In addition, studies of T regulatory cells, 
NK-T and dendritic cells will be performed (research non-billables). This can be performed on 
8 million cells. 
 
• Mixed lymphocyte cultures between the patient and each unit, and each unit against the other 
(Dr. James Young’s Laboratory). This can be performed on 5 million mononuclear cells. 
 
• Analysis of the Killer Ig-like receptor (KIR) genotype to assess if NK alloreactive cells are 
involved in unit predominance (Dr Katherine Hsu’s Laboratory). This will be performed on 
the post Ficoll cell pellet and 34- cells not required by Dr Moore’s laboratory. 
 
• Assessment of stem cell potential of each UCB (Dr. Malcolm Moore’s Laboratory). This will 
be performed on approximately 10-20 million mononuclear cells. 
 
As a maximum of 5% of each unit will be used for research, these studies may be limited by the 
number of cells available. If the post thaw infused TNC is less than 1 x 107/kg per unit no cells 
will be taken from either unit for research purposes. Above if > 1, a maximum of 5% of each unit 
will be taken. Experiments will be prioritized by the Principle Investigator according to the cell 
number available. Flow cytometry will take priority followed by a sample of mononuclear cells 
for Dr Young with the post Ficoll pellet going to Dr Hsu. Remaining cells will go to Dr Moore’s 
laboratory. The results of the laboratory studies will be correlated with the engraftment of each 
unit in the patients (see Section 14.0). 
 
10.7 Post Transplant Evaluation 
Post-HSCT evaluations are summarized in the following table. Scheduled evaluations for day 21 
may be performed +/-2 days, for day 28 may be performed +/-2 days, for day 60 and 100 may be 
done on +/-7 days, and for 6 and 9 months may be done +/-14 days, and 1 year, 2 years may be 
performed +/-30 days of the targeted date. Evaluations may be withheld if the treating physician 
feels that there is a strong contra-indication to perform the study (e.g. patient has relapsed and is 
terminally ill). Also, additional tests will be performed as clinically indicated.

will be assessed and graded according to current MSKCC guidelines. To determine acute GVHD 
grading, clinical data will be collected at least every 2 weeks for the first 3 months. 
 
Bone marrow aspiration with analysis for chimerism (DMP lab) must be performed on day 21 
(UCB) or day 28 (non-UCB) to ensure donor hematopoietic engraftment. BM aspiration should be 
repeated subsequently if clinically indicated to monitor disease relapse and donor engraftment. 
 
Additional blood (10-15 cc) will be obtained for follow-up research evaluations of immune 
recovery on approximately day +60. 
 
10.8 Evaluation > 100 days post HSCT 
 
These should include: history and physical examinations, blood counts and chemistries including 
liver function tests at a minimum of approximately every 6 weeks until 6 months, then at a 
minimum of approximately every three months for one year, and at approximately 3-6 month 
intervals until 2 years post transplant and then at least annually. The patient’s referring physician, 
in consultation with the MSKCC transplant physician, may assist with follow-up. 
 
Chronic GVHD will be diagnosed and graded according to current MSKCC guidelines. 
Assessments will be obtained at approximately day 100, 6 and 12 months, and annually after 
transplant and at additional time points as clinically indicated. Patients who develop chronic 
GVHD will be treated according to the current standard of care.

Bone marrow aspirate with analysis for chimerism and disease status should be performed at 6 
months, one and two years post transplant, as clinically indicated. 
 
Lymphoid immunophenotyping and function will be evaluated from 120 days as per MSKCC 
BMT standard of care guidelines. Patients will be vaccinated from 12 months after transplant as 
clinically appropriate and the response to vaccination should be documented. 
 
 
11.1 
TOXICITIES/SIDE EFFECTS 
 
11.2 
Toxicity Grading 
Toxicities will be graded on a scale of 0 to 4 as described by the NCI- Common Terminology for 
Adverse Events (CTCAE), version 3.0. 
 
 
 
11.1 
Total Body Irradiation (TBI) 
Likely 
• The dose of TBI in this regimen is very low and therefore the side-effects that are associated 
with high doses of radiation should be minimal. At the dose of radiation in this study mild 
nausea and vomiting, diarrhea, mucositis, fever, transient erythema may occur but should 
be mild and can be treated symptomatically. 
• Radiation contributes to the immune suppression induced by the chemotherapy and 
immune suppressing drugs. This is a major toxicity of the preparative regimen and is 
treated by donor stem cell infusion and aggressive supportive care. 
 
Less likely 
• High doses of radiation in combination with high dose chemotherapy may contribute to 
damage to vital organs such as the lung or the liver. This is sometimes associated with 
myeloablative conditioning and is not attributable to one specific agent. Such toxicity is 
highly unlikely with the doses in this protocol. 
• Late effects include cataracts, second malignancies and hypothyroidism and are possible 
but unlikely due to the low radiation dose. Hypothyroidism will be routinely monitored 
post transplant and treated with hormonal replacement as indicated. Radiation could 
contribute to the risk for sterility that is primarily from chemotherapy. The risk increases 
with the number of years since puberty. 
 
Dose Modifications 
• There are no dose modifications. 
 
11.2 
Cyclophosphamide 
Likely 
• Nausea and vomiting: virtually all patients will experience nausea and vomiting after 
intravenous cyclophosphamide. This can be significantly diminished with anti-emetics. 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 29 - 
 
 
 
 
• Diarrhea: most patients develop some diarrhea in the first week post cyclophosphamide. 
This is treated symptomatically. 
• Myelosuppression and immune suppression is a major toxicity and is treated by donor stem 
cell infusion and supportive care. 
• Alopecia is always seen but is usually reversible. 
• Late effects include sterility. 
 
Less Likely 
• Hemorrhagic cystitis is a potential complication and can be variable in severity. Severe 
cystitis is unlikely. The risk of cystitis will be reduced by the administration of a high 
volume fluid flush during and 24 hours after drug administration. Fluid weight gain and 
edema is associated with this fluid flush but is transient and can be treated with diuretics if 
necessary. 
• Syndrome of inappropriate anti-diuretic hormone (SIADH) can be seen but is transient and 
will spontaneously resolve after drug administration. 
Rare but serious 
• Cardiomyopathy has been described with cyclophosphamide but is very rare. 
 
Dose Modifications 
• There are no dose modifications. 
 
11.3 
Fludarabine 
Likely 
• Fludarabine may contribute to nausea, vomiting, mouth sores, and diarrhea which are 
primarily due to the cyclophosphamide. 
• Jaundice and elevations of liver enzymes have also been described. 
• Immune suppression is a major toxicity and is treated by donor stem cell infusion and 
supportive care. 
 
Less likely 
• Temporary erythema and desquamation 
 
Rare but serious 
• Effects on the nervous system are rare, but if they occur could include confusion, coma, 
weakness or numbness, loss of balance, difficulty walking, or loss of vision and could be 
very serious or lethal. 
 
Dose Modification 
• The dose will be modified based on Creatinine clearance as noted in section 9. 
 
11.4 
Melphalan 
Likely 
• Bone marrow suppression, complete ablation (bone marrow ablation is expected). 
• Gastrointestinal: Nausea, vomiting, anorexia, diarrhea, stomatitis, esophagitis, colitis 
• Alopecia 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 30 - 
 
 
 
 
• Fever 
• Transient liver dysfunction 
• Renal or bladder dysfunction (increased BUN, creatinine, necrosis) may be seen. 
 
Less likely 
• Pulmonary fibrosis, respiratory distress, has been rarely reported. 
 
Rare But Serious 
• Serious hypersensitivity reactions: Edema, rash, anaphylaxis. 
 
Dose Modifications 
• There are no dose modifications. 
 
11.5 
Tacrolimus 
• The major toxicity of Tacrolimus is immune suppression which leads to increased risk for 
infection. This is managed with aggressive supportive care with both prophylaxis and 
treatment of infectious complications. 
• Renal dysfunction is common and is treated by good hydration and reduction of the dose 
if necessary. Electrolyte abnormalities involving potassium and magnesium are also 
common and electrolytes must be closely monitored. 
• Increased blood pressure is common and is treated with anti-hypertensive medication(s). 
• Neurological side effects: Tremor (common), seizures (rare), ataxia, cortical blindness 
(rare), and peripheral neuropathies. 
• Gastrointestinal complaints including anorexia, nausea, and ileus. 
• Other potential side-effects include liver toxicity, hyperglycemia, hirsutism, capillary leak 
syndrome (rare), hemolytic anemia (rare), and thrombotic thrombocytopenic purpura 
(rare).  In addition there is an infusional toxicity from the cremaphor diluent.  . 
 
11.6 
Sirolimus 
• The major toxicity of Sirolimus is immune suppression which leads to increased risk for 
infection. This is managed with aggressive supportive care with both prophylaxis and 
treatment of infectious complications. 
• The primary toxicities of sirolimus are hypertriglyceridemia, hypercholesterolemia, mild 
thrombocytopenia, anemia, leukopenia, hypokalemia, elevated LDH, arthralgia, epistaxis, 
edema, and infections. 
• Clinically significant elevations in hepatic transaminases without sequelae were noted in 
the prior studies with this drug. However, the incidence of veno-occlusive disease of the 
liver was not noted to be higher than expected in trials of unrelated transplantation. 
• A syndrome of thrombotic microangiopathy, comprised of microangiopathic hemolytic 
anemia, thrombocytopenia and renal dysfunction has been described in association with 
sirolimus and tacrolimus use.

• Renal dysfunction: Decrease in creatinine clearance, renal wasting of magnesium and 
calcium, hypertension. Hypertension may be exacerbated by the concomitant use of 
corticosteroids. 
• Hepatic dysfunction: Elevation in serum bilirubin and occasionally in serum 
transaminases. 
• Mucositis: Mucositis secondary to the cytoreduction may be potentiated following the use 
of methotrexate post transplant. 
 
11.8 
Mycophenolate mofetil (MMF) 
• The major toxicity of MMF is immune suppression which leads to increased risk for 
infection. This is managed with aggressive supportive care with both prophylaxis and 
treatment of infectious complications. 
• Other potential side-effects include myelosuppression, headache, insomnia, aches and 
pains, rash, nausea, anorexia and diarrhea. 
• There are no dose modifications. 
• There is also a very rare side effect known as Progressive Multifocal Leukoencephalopathy 
(PML), which is a progressive disease of the nervous system that can cause severe 
disability or death. A very small number of cases of PML have been reported in patients 
treated with MMF. PML can cause hemiparesis, apathy, confusion, cognitive deficiencies 
and ataxia. 
 
11.9 
Cyclosporine-A (CSA) 
• The major toxicity of CSA is immune suppression which leads to increased risk for 
infection. This is managed with aggressive supportive care with both prophylaxis and 
treatment of infectious complications. 
• Renal dysfunction is common and is treated by good hydration and reduction of the dose 
if necessary. Electrolyte abnormalities involving potassium and magnesium are also 
common and electrolytes must be closely monitored. 
• Increased blood pressure is common and is treated with anti-hypertensive medication(s). 
• Neurological side effects include tremor (common), seizures (rare), confusion, ataxia, 
cortical blindness (rare), and peripheral neuropathies and are usually reversible with 
cessation of the medication. 
• While mild to moderate microangiopathic hemolysis is relatively common, serious 
thrombotic thrombocytopenic purpura (TTP) is rarely seen. 
• Gastrointestinal side-effects include anorexia and nausea, swollen gums, and 
hyperbilirubinemia. 
• Skin changes include hirsutism and gingival hyperplasia. 
• Dose may be modified for evidence of CSA toxicity. 
 
11.10 G-CSF (Neupogen) 
• Side-effects of G-CSF are generally mild, include bone pain, headaches, body aches, 
fatigue, edema and nausea and are managed with supportive care. Pleuro- or pericarditis 
are seen rarely and are managed by cessation of the medication and corticosteroids if 
necessary. 
 
11.11 Mesna (Mesnex®) 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 32 - 
 
 
 
 
• Mesna has no systemic side effects. Mesna is a uroprotectant and is being used 
concomitantly with the high dose cyclophosphamide. There are no dose modifications. 
 
11.12 Blood product and HSC infusions 
• Infusions of blood or HSC products may produce volume overload which can be managed 
with diuretics. They may also induce allergic reactions of variable severity, many of which 
can be prevented or mitigated by premedication with antipyretics, antihistamines, and 
narcotics. These products may also transmit serious infections (e.g., CMV, hepatitis, HIV). 
To circumvent this, donors are screened according to AABB and FACT guidelines. CMV 
antibody negative blood products will be used in CMV seronegative individuals whenever 
possible. All blood products (other than the HSC graft) are irradiated to circumvent the risk 
of GVHD caused by contaminating lymphocytes. 
• Toxicities potentially associated with the infusion of the thawed UCB graft include DMSO 
toxicity and side effects from red cells and may include changes in heart rate or rhythm, 
changes in blood pressure, fever, chills, sweats, nausea/vomiting, diarrhea, abdominal 
cramping, headache, dyspnea, presence of DMSO taste and odor, hemoglobinuria, and 
acute renal failure. However due to hydration and pre-medication, severe toxicities are 
unlikely. 
 
The definitions and reporting of serious adverse events (SAEs) is defined in Section 17.2. 
 
12.1 
CRITERIA FOR THERAPEUTIC RESPONSE/OUTCOME ASSESSMENT 
 
12.2 Primary Endpoint 
 
The primary end-point of this study is the progression-free survival (survival without progression 
of malignant disease from what is present at pre-HSCT disease staging) at 1 year. Subsequent 
survival will be monitored as a secondary endpoint. Other important outcomes include: 
 
12.3 Failure of Neutrophil Recovery and/or Donor Engraftment 
 
As this is a reduced intensity or NMA allograft protocol neutrophil recovery after transplants and 
donor engraftment are not synonymous and must be considered separately. The following 
definitions will be used: 
 
• The day of neutrophil recovery is the 1st day of 3 consecutive days of absolute neutrophil 
count (ANC) at or above 500 after the 1st post-UCBT nadir. 
• Donor chimerism will be defined as either partial (10-89% donor) or complete (> 90% 
donor) and should be recorded as to whether it is sampled from the patient's marrow or 
peripheral blood. In the case of UCBT, record which UCB unit engrafts (by unit number). 
If both UCB donors engraft, the total donor chimerism (contribution of each donor added 
together) as well as the contribution of each donor individually should be documented. 
• Primary graft failure = no neutrophil recovery by day 42 (regardless of donor chimerism) 
or autologous recovery (ANC recovery but < 10% donor in blood and BM) by day 42. 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 33 - 
 
 
 
 
• Secondary graft failure = loss of ANC to < 500/µL for 14 consecutive days after initial 
recovery or loss of donor chimerism to < 10% donor after primary donor engraftment has 
been achieved not due to progressive malignancy within the marrow. 
• Successful primary donor engraftment = neutrophil recovery within the first 42 days after 
transplant and partial/complete donor chimerism (> 10%). 
• Successful sustained donor engraftment = successful primary donor engraftment without 
subsequent graft failure beyond 42 days. This will be reported along with the median 
(range) of total donor chimerism at serial time points post-UCBT. 
Patients with suspected graft failure will be evaluated with bone marrow biopsy to assess BM 
cellularity and assess for residual or recurrent disease, culture for viral pathogens potentially 
causing graft failure including CMV and HHV6, and molecular analyses of marrow. Patients who 
suffer failure of donor engraftment will be managed with supportive care if they have autologous 
recovery and adequate hematopoiesis, or re-infused with autologous cryopreserved stem cells (if 
available) or a second HSC graft if they are aplastic. 
 
12.4 Graft-Versus-Host Disease (GVHD) 
 
Acute GVHD is manifested by skin rash, nausea, vomiting, diarrhea and ulceration of the 
intestines, hyperbilirubinemia and hepatitis, and suppressed or delayed recovery of the 
hematopoietic and immune system. Standard clinical criteria, and histological grading of skin, 
liver or gastrointestinal pathology where possible, will be used to establish and grade acute GVHD. 
 
In the first 100 days after transplant patients will be assessed by a transplant physician for the 
development of acute GVHD approximately weekly. Data will be collected approximately every 
2 weeks to characterize the severity of symptoms and signs caused by GVHD and to evaluate 
possible confounding factors. 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 or absence of urinary mixing and estimates of true diarrhea volume, 
presence of abdominal cramps or frank blood in the stool or melena, concomitant causes of GI 
symptoms other than GVHD, biopsy results, identification of any agents used for treatment and 
autopsy results if applicable. 
 
Patients with moderate to severe acute GVHD (grade II-IV) will be treated in standard fashion 
with high-dose IV methylprednisolone as per standard of care. Patients failing to respond to 
steroids will be considered for treatment with standard or experimental immunosuppressive agents. 
 
Chronic GVHD is characterized to varying degrees by sclerosis of lacrimal and salivary ducts, 
scleroderma-like changes of the skin, chronic inflammation and scarring of the gastrointestinal 
tract with consequent malabsorption and diarrhea, inflammation of the liver, suppression of the 
immune system and occasionally other auto-immune phenomena (eg auto-immune hemolysis) or 
involvement of other organs (eg pulmonary involvement). Chronic GVHD will be diagnosed and 
graded according to the criteria of Sullivan and treated with standard or experimental 
immunosuppressive therapy. Patients will be assessed for chronic GVHD at day 100, 6 months 
and annually after transplant, and more frequently if clinically indicated.

12.5 Transplant related mortality (TRM) 
 
TRM is defined as death at any time from the commencement of pre-transplant conditioning due 
to any cause other than disease relapse with the exception of automobile or other accidents. The 
incidence of TRM at day 180 after allo transplant is a secondary end-point of the study. Also, 
stopping rules are in place to consider cessation of the study if TRM at day 100 after HSCT is in 
excess of 35%. 
 
12.6 Disease Relapse or Progression 
 
Relapse of malignancy, or progression of disease from the base-line documented pre-allo 
transplant, is a secondary endpoint of this study and will be defined by an increasing number of 
malignant cells of recipient origin in the marrow over 5%, by the presence of circulating malignant 
cells, pathologic lymphadenopathy or by the presence of malignant cells at any other site. 
Radiologic studies, flow cytometric analysis or molecular studies of the marrow and/or peripheral 
blood, and/or biopsy of lymph nodes or other sites may also be obtained for the diagnosis of relapse 
or disease progression. 
 
Hodgkin’s relapse or disease progression will be defined using CT and PET criteria: 
 
Complete remission is defined as resolution of all disease related symptoms and normalization of 
PET scan and of bone marrow involvement on morphologic exam. 
 
Partial remission (PR) is ≥ 50% decrease in the sum of product of diameters (SPD) of the 6 
largest dominant lymph nodes and of sites of organ involvement, no increase in size or number of 
involved lymph nodes or organs, decrease in PET avidity. 
 
Stable disease (SD) is less than PR but is not progressive disease. 
 
Progressive/ relapsed disease (PD) is appearance of a new lesion ≥50% increase in SPD of more 
than one node or in greatest diameter of any previously identified node >1 cm in its short axis. 
 
12.7 
Immunologic Recovery 
 
Immunophenotyping of T-cells, B-cells, and NK cells, and T-cell proliferations in response to non- 
specific mitogens and specific antigens, will be performed at serial time points after transplant to 
measure immune recovery. At approximately 60 days (2 months post-transplant) these will be 
performed only in UCB recipients and considered research studies as they will not guide clinical 
decision-making. From 4 months these studies will guide clinical decisions in terms of 
continuation of prophylactic antibiotics and are therefore both clinically indicated and billable. 
Patients will receive supplemental IV immunoglobulin (Ig) to prevent infection for at least 3 
months post HSCT in recipients of UCB or URD donor and possibly longer if IgG levels are < 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 35 - 
 
 
 
 
500. Subsequently, Ig levels will be tested at approximately 6, 12, 18 and 24 months post transplant 
to guide further IgG supplementation. Patients may be re-immunized as from 12 months post- 
transplant and the response to vaccination will be documented. 
 
13.0    CRITERIA FOR REMOVAL FROM STUDY 
 
If at any time the patient is found to be ineligible for the protocol as designated in the section on 
Criteria for patient/subject eligibility (eg a change in diagnosis), the patient will be removed from 
the study. Participants may be removed from the study if at any time it is determined to be in the 
participant’s best interest to do so. Also patients may be removed from the study if requested by 
the patient. Management will depend on where they are in their treatment course. Such patients 
will receive appropriate supportive care. 
 
14.1 
BIOSTATISTICS 
 
14.2 Clinical Endpoints 
 
This is a phase 2 study of salvage chemotherapy followed by HSCT in patients with high-risk or 
relapsed Hodgkin Lymphoma. After treatment with salvage chemotherapy, patients that have a 
suitable donor and do not progress after the chemotherapy will receive an allogeneic HSCT. For 
this study, a patient will be classified as a success, if he or she obtains a response as a result of 
salvage chemotherapy, undergoes an allogeneic HSCT, and remains progression free for one year 
after HSCT. Pre-allograft conditioning will be determined by remission status post salvage 
chemotherapy assessed at the time of pre-allograft work-up. Patients who have stable disease or 
are in PR will receive a reduced intensity preparative regimen of Melphalan and Fludarabine 
(Mel/Flu). Patients in CR will receive a non-myeloablative preparative regimen of 
Cyclophosphamide, Fludarabine and low dose total body irradiation (Cy/Flu/TBI). 
 
This is a revision of a phase 2 trial designed to investigate the efficacy and safety of salvage 
chemotherapy followed by HSCT in patients with high-risk or relapsed Hodgkin Lymphoma. In 
response to the slow accrual, the original treatment strata A (upfront patient not eligible for 
autologous transplant) and B (relapse after autologous transplant) were merged. For this study, a 
patient will be classified as a success, if he or she responds due to salvage chemotherapy, 
undergoes an allogeneic HSCT, and remains progression free for one year after HSCT. Currently, 
5 of 15 patients are recorded a success on this study. These 15 patients are incorporated into a 
Simon two-stage minimax design that differentiates between success rates of 0.20 and 0.45. In the 
first stage, since more than 3 successes out of 15 patients were observed, an additional 9 patients 
will be accrued for a total of 24 patients. The salvage chemotherapy followed by HSCT would be 
considered worthy of further study in this patient population if 8 or more successes from the 24 
patients were observed. This two-stage design has power 0.90 if the population success proportion 
is 0.45 and has a type 1 error equal to 0.10 at the success probability 0.20. 
 
 
Patients with HL that are suitable for allograft but are referred for transplant after salvage 
chemotherapy is underway or complete may be transplanted on this protocol. While they will 
contribute to the allograft outcome data, they will not be part of the primary efficacy analysis 
described above. It is anticipated that approximately 6 patients will be treated through this course. 

Memorial Sloan Kettering Cancer Center 
IRB Number: 07-147 A(12) 
Approval date: 04-Oct-2022 
- 36 - 
 
 
 
 
 
 
The maximum sample size for this study is anticipated to be 30 patients (24 on ITT study, and 6 
transplanted without salvage chemotherapy administered on the protocol). The accrual period will 
be approximately 4-5 years with a follow-up period of 2 years post-transplant. 
At the conclusion of the study, the Kaplan-Meier estimate of the progression free survival 
probability and the survival probability over time will be computed. Progression-free survival is 
defined as the time from the start of chemotherapy to the time of death, disease progression, or last 
follow-up. Kaplan-Meier estimates of progression free and overall survival will be computed for 
subsets of transplant patients (patients treated with salvage chemotherapy at MSKCC and all 
transplant patients), starting from the time of transplant. For the transplant subsets, the time to 
neutrophil and platelet engraftment, and the time to acute and chronic GVHD will be assessed 
using the cumulative incidence function. Also, the acute GVHD outcome by grade and the patient 
response to vaccination after allograft will be recorded for each patient and summary measures of 
these outcomes will be produced. The reasons for not receiving an allograft (lack of disease 
response to chemotherapy, no donor, or not fit for allograft due to treatment complications) will 
also be reported. 
 
In order to reduce patient risk, the design includes a study evaluation boundary in the event of 
excessive day 100 TRM after HSCT during the accrual period. The boundary is derived using a 
repeated significance test and is summarized in the table below. If the boundary is crossed, it will 
be determined whether the treatment related deaths were composed of a well-defined subgroup of 
patients (e.g. the conditioning regimen). If this is found to be the case, the eligibility criteria for a 
future study may be refined to exclude these patients. 
 
Table – Stopping boundary for day 100 TRM. Boundary based on an acceptable TRM rate 
of 0.15 and an unacceptable TRM rate of 0.40. The repeated significance test using this 
boundary has size 0.10 and power 0.90.

At the conclusion of the trial, the time to neutrophil and platelet recovery, the time to acute and

using the cumulative incidence function. 
 
 
 
 
14.3 Laboratory Studies 
 
Laboratory research studies will be performed investigating: 
• The determinants of unit predominance to facilitate the understanding of the biology of double 
unit UCBT (see Section 10.5). The results of these studies will be correlated with the 
engraftment of each unit in the patients testing if the laboratory results predict or correlate with 
unit predominance in the patient. The Wilcoxon rank sum test will be used to test the

continuous correlates and the Fisher's exact test will be used for the binary correlates. The data 
collected on this protocol will be analyzed in aggregate with other clinical protocols of double 
unit UCBT. 
• Immune recovery as measured by immunophenotyping of T-cells, B-cells, and NK cells, and 
T-cell proliferations in response to non-specific mitogens and specific antigens at serial time 
points after transplant. The results of these studies will be correlated with serious infectious 
complications. The Wilcoxon rank sum test will be used to test the continuous correlates and 
the Fisher's exact test will be used for the binary correlates.

16.1 
DATA  MANAGEMENT ISSUES 
A Research Study Assistant (RSA) will be assigned to the study. The responsibilities of 
the RSA 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 Database 
(CRDB). Source documentation will be available to support the computerized patient 
record. 
 
16.2 
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 

Memorial Sloan Kettering Cancer Center

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. 
 
16.3 
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. The MSKCC Data and Safety 
Monitoring 
Plans 
can 
be 
found 
on 
the 
MSKCC 
Intranet 
at:  
http://mskweb2.mskcc.org/irb/index.htm 
 
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 it’s 
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 and 
the monitoring procedures will be established at the time of protocol activation 
 
17.1 
PROTECTION OF HUMAN SUBJECTS 
 
Risks: From the studies that have been done so far it appears that allo-HSCT can safely be 
performed in patients with advanced HL and that these patients may benefit from the treatment. 
However, given this is a new treatment approach, it is possible that there are side effects that have 
not yet been seen. 
 
Benefits: The information from this study will help future cancer patients. 
 
Possible toxicities/side effects: Toxicities and side effects of the agents used are listed in section 
11 and reporting of serious adverse events is found in section 17.2. 
 
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: Alternative treatment options will be presented to the patient prior to taking part in 
this study. Alternative treatment options may include getting treatment 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, 
including the allograft, all hospitalizations and any transplant complications. Pre-authorization for 
allogeneic transplant will be cleared with the health plan/ insurance company prior to allograft 
admission. Patients will not be paid for taking part in this study. Once the cord blood units have 
been shipped, the patient’s health plan/ insurance company will need to pay for the costs of the 
units even if they are not administered.  Research tests will be done at no cost to the patient. 
 
Confidentiality: Every effort will be made to maintain patient confidentiality. Research and 
hospital records are confidential. 
 
17.2 
Privacy 
 
 
MSKCC’s Privacy Office may allow the use and disclosure of protected health information 
pursuant to a completed and signed Research Authorization form. The use and disclosure 
of protected health information will be limited to the individuals described in the Research 
Authorization form. A Research Authorization form must be completed by the Principal 
Investigator and approved by the IRB and Privacy Board. 
 
17.2 
Serious Adverse Event (SAE) Reporting 
 
An adverse event is considered serious if it results in ANY of the following outcomes: 
• 
Death 
• 
A life-threatening adverse event 
• 
An adverse event that results in inpatient hospitalization or prolongation of existing 
hospitalization 
• 
A persistent or significant incapacity or substantial disruption of the ability to conduct normal 
life functions 
• 
A congenital anomaly/birth defect 
• 
Important Medical Events (IME) that may not result in death, be life threatening, or require 
hospitalization may be considered serious when, based upon medical judgment, they may 
jeopardize the patient or subject and may require medical or surgical intervention to prevent 
one of the outcomes listed in this definition 
Note: Hospital admission for a planned procedure/disease treatment is not considered an SAE. 
 
SAE reporting is required as soon as the participant signs consent.  SAE reporting is required for 
30-days after the participant’s last investigational treatment or intervention. Any events that occur 
after the 30-day period and that are at least possibly related to protocol treatment must be 
reported. 
 
If an SAE requires submission to the IRB office per IRB SOP RR-408 ‘Reporting of Serious 
Adverse Events’, the SAE report must be sent to the IRB within 5 calendar days of the event. The 
IRB requires a Clinical Research Database (CRDB) SAE report be submitted electronically to the 
SAE Office as follows:

For all other trials: Reports that include a Grade 5 SAE should be sent to  
saegrade5@mskcc.org.  All other reports should be sent to sae@mskcc.org. 
The report should contain the following information: 
Fields populated from CRDB: 
• 
Subject’s initials 
• 
Medical record number 
• 
Disease/histology (if applicable) 
• 
Protocol number and title 
 
Data needing to be entered: 
•

• 
The grade of the event 
• 
Relationship of the adverse event to the treatment (drug, device, or intervention) 
• 
If the AE was expected 
• 
The severity of the AE 
• 
The intervention 
• 
Detailed text that includes the following 
o A explanation of how the AE was handled 
o A description of the subject’s condition 
o Indication if the subject remains on the study 
• 
If an amendment will need to be made to the protocol and/or consent form 
• 
If the SAE is an Unanticipated Problem 
 
The PI’s signature and the date it was signed are required on the completed report. 
 
The current study includes two treatment phases, salvage chemotherapy and HSCT. All patients 
will be followed for safety and toxicity related to the study. Toxicities will be graded using CTC 
guidelines (v3.0). This will occur during both treatment phases of the study. An adverse event is 
any adverse change from the patient’s baseline (pretreatment) condition, including any clinical 
status change or clinically significant laboratory test value abnormality that occurs during the 
course of the clinical study whether it is considered related to the treatment or not. 
 
For the 1st treatment phase of the study (salvage chemotherapy), elective hospitalizations to 
administer the cytoreduction regimen are not adverse events. Grade 3 or 4 neutropenia and/or 
thrombocytopenia will not be considered an adverse event unless its duration exceeds 28 days. 
 
Potentially serious toxicities are an expected part of transplant therapy. However, for the purposes 
of this study, serious adverse events (SAEs) which will be reportable for the second part of the 
study (HSCT) will be defined according to the current MSKCC BMT program guidelines (Adult 
and Pediatric BMT Adverse Event Reporting Standard Operating Procedures, version 1.0 dated 1 
December 2011).

INFORMED CONSENT PROCEDURES 
 
Before protocol-specified procedures are carried out, consenting professionals will explain full 
details of the protocol and study procedures as well as the risks involved to participants prior to 
their inclusion in the study. Participants will also be informed that they are free to withdraw from 
the study at any time. All participants must sign an IRB/PB-approved consent form indicating 
their consent to participate. This consent form meets the requirements of the Code of Federal 
Regulations and the Institutional Review Board/Privacy Board of this Center. The consent form 
will include the following: 
 
1. The nature and objectives, potential risks and benefits of the intended study. 
2. The length of study and the likely follow-up required. 
3. Alternatives to the proposed study. (This will include available standard and 
investigational therapies. In addition, patients will be offered an option of supportive care 
for therapeutic studies.) 
4. The name of the investigator(s) responsible for the protocol. 
5. The right of the participant to accept or refuse study interventions/interactions and to 
withdraw from participation at any time. 
 
Before any protocol-specific procedures can be carried out, the consenting professional will fully 
explain the aspects of patient privacy concerning research specific information.  In addition to 
signing the IRB Informed Consent, all patients must agree to the Research Authorization 
component of the informed consent form. 
 
Each participant and consenting professional will sign the consent form. The participant must 
receive a copy of the signed informed consent form. 
 
Patients recruited to this study are individuals with high-risk or relapsed HL who are suitable 
allograft candidates. Prior to consideration for transplant, all patients undergo salvage 
chemotherapy, either at MSKCC or at an outside institution. Those patients receiving salvage 
chemotherapy at MSKCC are first required to sign part I of the informed consent in order to take 
part in the intention to treat portion of this study. Patients who received salvage chemotherapy at 
an outside institution do not take part in this aspect of the study and are not required to sign consent 
part I. All patients who do not have POD after salvage chemotherapy, and who have both suitable 
HSC donors and a satisfactory pre-allograft work-up sign part II of the informed consent and 
proceed to the allograft portion of the study. Patients who fail any of these 3 criteria will be off 
study and considered treatment failures. Pre-allograft conditioning will be determined by 
remission status post salvage chemotherapy assessed at pre-allograft work-up. Those patients with 
stable disease or in PR will be placed into study Arm A, the reduced intensity preparative regimen 
of Mel/Flu and those in CR will be placed into study Arm B, the NMA preparative regimen of 
Cy/Flu/TBI. Cytoreduction will be followed by transplantation using the best available donor 
(sibling PBSC, URD HSC or BM, or UCB). 
 
Prior to consideration for this study, all patients undergo a series of consultations discussing the 
risks and potential benefits of salvage chemotherapy followed by allogeneic stem cell transplant

and the different procedures which are a normal part of the transplant course. The risks and 
potential benefits of the transplant procedure, as well as the participation in a research protocol are 
also discussed. 
 
Only the principal investigator or the attending physicians named as consenting professionals and 
designated in section 15 will be qualified to conduct the informed consent process. They will 
explain the nature of the investigation and the risks involved to each patient prior to enrollment 
and will obtain written, informed consent. The patient will also be informed that he/she is free to 
voluntarily withdraw from study at any time. 
 
All patients must sign three IRB-approved consent forms indicating their consent to participate. 
Sibling donors will also sign a consent form in triplicate, which reviews the risks and alternatives 
to G-CSF-elicited PBSC mobilization, and collection of PBSC via leukapheresis. Unrelated donors 
will provide written consent for marrow donation or HSC mobilization and collection according 
to the consent procedures of the National Marrow Donor Program. 
 
The informed consent will meet FDA regulations, the requirements of 21 CFR 50.20 and contain 
the information required by each of the eight basic elements of 21 CFR 50.25 (a), and each of the 
six elements of 21 CFR 50.25(b) that is appropriate to the study. One original signed consent form 
will become part of the patient’s medical record. Each patient will receive a copy of the signed 
consent form. The third consent form will be on file in the research file.
