Brief summary:
To see if it is possible to use short-duration tacrolimus after a peripheral blood stem cell transplant in certain malignancies that are considered difficult to engraft.

Detailed description:
The main goal is to learn whether a drug called tacrolimus, which is an immune-lowering drug (an immunosuppressant) given after transplant to help prevent certain complications, can be given safely for a shorter period of time than it has been in the past. The experiences with immunosuppression duration with other allogeneic HSCT platforms cannot be directly extrapolated to the high-dose posttransplantation cyclophosphamide platform (another type of immunosuppressant given after transplant to help prevent GVHD). There are presently no published data on the minimum required duration of tacrolimus after nonmyeloablative HSCT that includes high-dose Cy as part of postgrafting immunosuppression. The effectiveness of high-dose posttransplantation Cy in GVHD prevention, however, permits the investigation of this question. At the present time there are few or no cures for diseases studied on this trial outside of a bone marrow or peripheral blood transplant. The peripheral blood for this transplant comes from a relative who is a half-match or "haplo" match to the participant. Possible donors include parents, siblings, and children. In order to help the bone marrow grow, or "take", inside the body, participants will receive chemotherapy and radiation before the transplant. After the transplant participants will receive high doses of cyclophosphamide (Cytoxan®) along with other medications to lower the immune system, such as tacrolimus. These medications may lower the risk of graft versus host disease (GVHD) and of rejection of the peripheral blood graft.

Arms:
arm 1: Non-myeloablative peripheral blood stem cell transplant (PBSCT) with a fludarabine (Flu), cyclophosphamide (Cy), total body irradiation (TBI) preparative regimen and post-transplant Cy, mycophenolate mofetil (MMF), and tacrolimus as GVHD prophylaxis. Tacrolimus will be stopped at either Day 90 or Day 180 depending on GVHD status. arm 2: Non-myeloablative peripheral blood stem cell transplant (PBSCT) with a fludarabine (Flu), cyclophosphamide (Cy), total body irradiation (TBI) preparative regimen and post-transplant Cy, mycophenolate mofetil (MMF), and tacrolimus as GVHD prophylaxis. Tacrolimus will be stopped at either Day 60 or Day 180 depending on GVHD status.

INTRODUCTION 
Recent advances in allogeneic blood or marrow transplant (HSCT) platforms for hematologic malignancies 
have substantially lowered transplant-related morbidity both in the HLA-matched and partially HLA-
mismatched settings.  One of these major advances is the incorporation of high-dose posttransplantation 
cyclophosphamide (Cy) for prophylaxis of graft-versus-host-disease (GVHD) and graft rejection, as developed 
at Johns Hopkins.1  Historically, we have used this approach for HSCTs which have used marrow as the graft 
source. We and the field note challenges to engraftment in diseases such as myelodysplastic syndrome 
(MDS), chronic lymphocytic leukemia (CLL), myeloproliferative diseases (MPD) and multiple myeloma (MM).  
More recently we have chosen to move towards peripheral blood stem cells (PBSC) as the graft source in 
these malignancies as there is data that there is lower graft failure with PBSC as well as overall survival (OS) 
and progressive free survival (PFS) improvements.2    For nonmyeloablative, related donor, HLA haploidentical 
or matched HSCT, and nonmyeloablative, unrelated donor HSCT, our postgrafting immunosuppression has 
standardly consisted of two doses of high-dose Cy, mycophenolate mofetil (MMF) for one month, and 
tacrolimus without taper until Day 180.  It is known that transplants using PBSCs have higher rates of GVHD 
than those from marrow sources but the GVHD may translate into better outcomes in terms of OS and PFS.3,4 
It stands to reason that some GVHD in these patients is a good thing and we believe there are several 
potential advantages to shorter-duration pharmacologic immunosuppression to be used in conjunction with 
PBSC grafts to improve outcomes in these patients. The current study builds on our transplantation platform 
that incorporates high-dose posttransplantation Cy, by investigating the feasibility and safety of shorter 
planned durations of pharmacologic immunosuppression with tacrolimus in patients receiving PBSC 
transplants for these malignancies which are challenging to engraft. 
 
1.1  
Stem cell source 
There has been a great deal of discussion on the importance of stem cell source on the risk of chronic graft-
versus-host disease5-9. Several studies have addressed this issue in the related setting. Of the eight 
randomized trials published10-18 only one reported astatistically significant increase in grades II-IV acute graft-
versus-host disease with the use of peripheral blood stem cells when compared to bone marrow (52 vs. 
39%)16. Regarding chronic graft-versus-host disease,  the results are as follows: 3 studies have shown an 
increase of chronicgraft-versus-host disease with peripheral blood stem cells as opposed to bone 
marrow12,16,19. One study showed a trend towards increase in chronic graft-versus-host disease with the use 
of peripheral blood stem cells19. A meta-analysis by Cutler et al. confirmed that both, acute and chronic graft-
versus-host disease are more common after peripheral blood stem cells than bone marrow7. Registry data 
showed in pediatric patients that chronic graft-versus-host disease was more frequent (as well as higher 
mortality) after peripheral blood stem cells than after bone marrow8. In adults, chronic graft-versus-host 
disease is also more prevalent20. Umbilical-cord stem cells have also been a source of grafts in children and 
young adults. As children tolerate mismatches better than adults, interpretation of risk in this group is difficult 
but it seems that the rate of chronic graft-versus-host disease is low for this stem cell sources, especially 
considering that almost all grafts are 1-3 antigen mismatches21,22. In the unrelated setting, a clinical trial by 
the BMT CTN comparing bone marrow versus peripheral blood did not detect significant survival. Peripheral-
blood stem cells may reduce the risk of graft failure (the overall incidence of graft failure in the peripheral-
blood group was 3% [95% CI, 1 to 5], versus 9% [95% CI, 6 to 13] in the bone marrow group [P=0.002]), 
whereas bone marrow may reduce the risk of chronic GVHD at 2 years (peripheral-blood group was 53% [95% 
CI, 45 to 61], as compared with 41% [95% CI, 34 to 48] in the bone marrow group [P=0.01].17  The proportion 
of patients with extensive chronic GVHD was higher in the peripheral-blood group than in the bone marrow 
group (48% [95% CI, 42 to 54] vs. 32% [95% CI, 26 to 38], P<0.001). Among patients who were alive at 2 years, 
57% of the patients in the peripheral-blood group were receiving immunosuppressive therapy, as compared 
with 37% of those in the bone marrow group (P=0.03). There were no significant between-group differences 
in the incidence of acute GVHD or relapse17.

1.2 
Rationale for shorter-duration immunosuppression 
With the advent of posttransplantation high-dose Cy, our nonmyeloablative allogeneic HSCT platforms have 
been associated with acceptable rates of acute GVHD, graft failure, and nonrelapse mortality (NRM) that are 
similar to those seen with HLA-matched transplants.23,24  However, relapse remains a major problem, and 
approaches that augment the anti-tumor efficacy of the transplant procedure are needed.  Transplantation 
platforms that minimize the amount of pharmacologic immunosuppression, but that carry acceptable rates 
of severe GVHD and graft failure, are desirable for a number of reasons.  Less pharmacologic 
immunosuppression has the potential to a) lower the risk of relapse by facilitating a graft-versus-tumor effect, 
and b) facilitate the development of immunotherapies in the transplant setting, including tumor vaccines.  In 
addition, it has the potential to lower the risk of opportunistic infections, and to lower the likelihood or 
severity of drug toxicities.  This may be very relevant in older MDS or CLL patients who suffer from 
nephrotoxicity and electrolyte disturbances from the calcineurin inhibitors. 
 
Extensive published data demonstrate that allogeneic HSCT can be associated with a clinically significant 
graft-versus-tumor (GVT) effect mediated by donor T cells specific for host histocompatibility antigens.  Yet, 
the T cells that mediate a GVT effect may also cause clinically significant GVHD.  Tacrolimus, a calcineurin 
inhibitor (CNI), blocks T cell activation and the production of interleukin-2, a critical growth factor for T cells 
including regulatory T cells that control autoimmunity.  CNI’s are used to prevent acute GVHD, but they are 
associated with an increased incidence of renal dysfunction, hypertension, opportunistic infection, and other 
complications. Sirolimus is similarly used and applied.   Importantly, CNI’s block T cell development in the 
thymus16,17 resulting in delayed immunologic reconstitution, and by suppressing T cell activation may block 
the GVT effect and increase the risk of disease relapse after allogeneic HSCT.18-20   
 
1.3 
High-dose posttransplantation cyclophosphamide 
The immunologic rationale for administering high-dose Cy after transplantation is that recently activated, 
alloreactive T cells (the cells most responsible for GVHD) are selectively sensitive to the toxic effects of this 
drug.25  High-dose Cy, when administered in a narrow window after transplantation, depletes alloreactive T 
cells from the donor and host and can inhibit both GVHD and graft rejection.25-30  As a form of drug-induced 
immunologic tolerance,31 the strategy of giving high-dose Cy after transplantation takes advantage of the 
heightened cytotoxic sensitivity of proliferating, alloreactive T cells over non-alloreactive, resting T cells to 
being killed by a DNA-damaging agent.32 Pre-clinical studies demonstrated that engraftment of major 
histocompatibility complex (MHC)-mismatched bone marrow could be achieved by conditioning mice with 
pretransplantation fludarabine and low dose (200 cGy) total body irradiation (TBI), with posttransplantation 
Cy.27  Additional studies demonstrated that posttransplantation Cy reduced the incidence and severity of 
GVHD in the setting of MHC-mismatched allogeneic HSCT after myeloablative conditioning.26  
After allogeneic HSCT, standard regimens of GVHD prophylaxis consist of a CNI (cyclosporine or tacrolimus) 
in combination with either methotrexate, MMF, or sirolimus.  However, a nonmyeloablative, partially HLA-
mismatched (haploidentical), related donor HSCT platform with high-dose posttransplantation Cy, MMF, and 
tacrolimus for GVHD and graft rejection prophylaxis has produced encouraging results24.  This approach has 
been associated with rapid and stable engraftment in most patients.24  Most importantly, this approach has 
carried acceptable rates of GVHD and NRM that parallel those seen with nonmyeloablative HLA-matched 
transplants (Figure 1).23,24,33,34  Cy, when administered at high doses after myeloablative, HLA-matched, 
related or unrelated donor HSCT, notably has been found to be effective single-agent prophylaxis against 
GVHD, obviating the need for CNI’s in this setting (Figure 1).35

1.4 
Nonmyeloablative HSCT with fludarabine, TBI, and posttransplantation cyclophosphamide 
Independent clinical trials have evaluated or are evaluating a nonmyeloablative, partially HLA-mismatched 
(haploidentical), related donor marrow transplant platform with high-dose posttransplantation Cy, 
tacrolimus, and MMF for GVHD and graft rejection prophylaxis.  Conditioning in these studies has historically 
consisted of fludarabine, low-dose Cy, and 200 cGy TBI.  The postgrafting immunosuppression regimen that 
underlies recent and ongoing research efforts at Johns Hopkins has been published.24,34  A combined analysis 
of two independent clinical trials for poor-risk hematologic malignancies was originally reported in 2008 (40 
patients at Johns Hopkins, 28 at Fred Hutchinson Cancer Research Center), evaluating the safety and efficacy 
of a high-dose posttransplantation Cy platform after outpatient nonmyeloablative conditioning and T-cell-
replete HSCT from partially HLA-mismatched, related donors (Figure 2).24  Following transplantation, high-
dose (50 mg/kg) Cy was administered on Day 3 (Seattle group), or on Days 3 and 4 (Hopkins).  Pharmacologic 
prophylaxis of GVHD was initiated on the day following completion of posttransplantation Cy with MMF until 
Day 35, and tacrolimus which was tapered to off by Day 180 (Seattle) or continued at full dose until Day 180 
(Hopkins).  Filgrastim 5 g/kg/day was administered until recovery of neutrophils to >1000/L: 
 
 
Figure 2. Treatment Schema in Previous Studies 
 
Median times to recovery of neutrophils and platelets were 15 and 24 days, respectively.  Graft failure 
occurred in 9 of 66 evaluable patients (12%); all but one patient with graft failure had recovery of autologous 
hematopoiesis with median times to neutrophil and platelet recovery of 15 days (range, 11-42) and 28 days 
(range, 0 – 395 days) respectively.  Engrafting patients achieved full donor chimerism rapidly; with few 
exceptions, donor chimerism in patients with sustained engraftment was virtually complete (>95%) by 2 
months after transplantation.  The cumulative incidences of acute grade II-IV GVHD and acute grade III-IV 
GVHD by Day 200 were <35% and <10%, respectively, on competing-risk analysis.  The groups did not differ 
significantly in the incidence of acute grade II-IV or III-IV GVHD, although the risk of chronic GVHD appeared 
to be lower with two doses of Cy. The cumulative incidence of extensive chronic GVHD by 1 year was only 5%

in the group with two doses of Cy. The cumulative incidences of relapse and NRM at 1 year were 51% and 
15% respectively on competing-risk analysis; however the event-free survival (EFS) probability at 1 year was 
only 34%.  Similar outcomes were seen in a recent analysis of 185 patients treated on these trials including 
follow-up phase II trial (J0457) of this approach.34  Interestingly, although increasing degrees of HLA mismatch 
between donor and recipient have historically been associated with greater GVHD and inferior survival after 
allogeneic HSCT, that analysis retrospectively found no such adverse effect of HLA mismatching using this 
approach in the haploidentical setting.34   
 
On an updated analysis of 212 patients with advanced hematologic malignancies, uniformly treated at Johns 
Hopkins with related donor, partially HLA-mismatched HSCT with fludarabine/Cy/TBI conditioning and 
postgrafting immunosuppression with 2 doses of Cy, MMF on Days 5-35, and full-dose tacrolimus on Days 5-
180, the 1-year EFS was 44%, and cumulative incidence of NRM by competing risk analysis was 8% by Day 
100 and 14% at 1 year.  The cumulative incidence of acute grade II-IV GVHD was 28% by Day 200, cumulative 
incidence of severe GVHD was only 4%, and the cumulative incidence of chronic GVHD was 14% by competing 
risk analysis (unpublished data).    
 
The same approach to nonmyeloablative HSCT using partially HLA-mismatched, related donors has been 
adopted at Johns Hopkins for HLA-identical donor HSCT.  In a phase I trial (J0169) of nonmyeloablative, 
matched sibling donor HSCT, Cy alone on Day 3, Cy alone on Days 3 and 4, or Cy on Days 3 and 4 with MMF 
was investigated with the latter being favored.  Although the optimal postgrafting immunosuppression after 
high-dose Cy is not defined, MMF plus a CNI is the industry-standard GVHD prophylaxis for nonmyeloablative 
conditioning (i.e. omission of a CNI is nonstandard).  At Johns Hopkins we have used the approach developed 
in over 200 nonmyeloablative haploidentical transplants described above in our nonmyeloablative matched 
unrelated donor (MUD) transplants, and have recently adopted this for our nonmyeloablative matched 
sibling transplants as well.  This is similar to most centers that use the same nonmyeloablative conditioning 
and GVHD prophylaxis for matched sibs and MUDs.  
 
In summary, HLA-haploidentical HSCT after non-myeloablative conditioning and using 2 doses of 
posttransplantation Cy followed by MMF for one month and tacrolimus for up to 6 months is a generally well-
tolerated procedure that can be administered largely in an intensified outpatient setting.  The toxicity of the 
procedure compares favorably to the toxicity of non-myeloablative transplantation using unrelated or even 
HLA-identical sibling donors.23 The major cause of treatment failure in this high-risk population is relapse, 
occurring in approximately 50% of patients by 1 year.  Therefore, investigations of strategies that may lower 
the risk of relapse are needed.  Towards this end, a strategy of reduced-duration pharmacologic 
immunosuppression is herein investigated. 
 
1.5 
Shortened-course immunosuppression 
MMF plus a CNI (i.e. tacrolimus or cyclosporine or sirolimus) is an industry-standard GVHD prophylaxis for 
nonmyeloablative conditioning.  However, optimal postgrafting immunosuppression after high-dose Cy is not 
defined, nor is the optimal type or duration of postgrafting immunosuppression fully defined in allogeneic 
HSCT in general.   
 
For example, in nonmyeloablative, HLA-matched HSCT with postgrafting immunosuppression consisting 
solely of MMF + cyclosporine, investigators at the Fred Hutchinson retrospectively evaluated three durations 
of cyclosporine: taper from Days 35 to 56, Days 56 to 77, or Days 56 to 180.36  Grafts were derived from 
peripheral blood stem cells.  There was no significant association between cyclosporine duration and the 
rates of acute grade II-IV GVHD (57%, 43%, and 49% respectively), extensive chronic GVHD, or NRM; however, 
longer duration of cyclosporine was associated with a lower risk of acute severe (grade III-IV) GVHD and lower

prevention and successful treatment of GVHD).   
 
In an older randomized trial of myeloablative, HLA-identical or one-antigen mismatched HSCT, where 
postgrafting immunosuppression consisted of methotrexate and cyclosporine with or without 
methylprednisolone, results suggested that cyclosporine could be stopped earlier (by Day 60) in patients 
without prior acute GVHD, whereas those with prior acute GVHD appeared to benefit from a longer course 
37.  In another randomized trial of myeloablative, HLA-matched related or unrelated donor HSCT, the risk of 
clinically extensive chronic GVHD and transplant-related mortality did not significantly differ in patients 
assigned to 6 months versus 24 months of cyclosporine.38  Other nonrandomized studies of myeloablative, 
HLA-matched sibling transplant have suggested a benefit to longer duration cyclosporine in chronic GVHD 
prevention.39  However, some studies have found an increased risk of relapse associated with higher doses 
of cyclosporine.40,41  
 
The experiences with immunosuppression duration with other allogeneic HSCT platforms cannot be directly 
extrapolated to the high-dose posttransplantation Cy platform.  Immunosuppression must be sufficient to 
prevent graft failure and to prevent excessive rates of GVHD including severe GVHD; yet extended-course 
immunosuppression may increase the risk of infection, drug toxicity, and relapse.  There are presently no 
published data on the minimum required duration of tacrolimus or other immunosuppression after 
nonmyeloablative HSCT that includes high-dose Cy as part of postgrafting immunosuppression.  The 
effectiveness of high-dose posttransplantation Cy in GVHD prevention, however, permits the investigation of 
this question. 
 
Addendum: Cohort 1 with patients stopping IST on Day 90 was completed with favorable rates of GVHD and 
thus cohort 2 has been added to investigation cessation at Day 60.  Sirolimus has been an institutional 
standard favored over tacrolimus for once daily dosing as well as less nephrotoxicity.  This has now become 
first line in the majority of patients to start Day +5.

OBJECTIVES 
 
2.1 
Primary objective  
In nonmyeloablative, related or unrelated donor, partially HLA-mismatched or HLA-matched PBSC 
transplant with post-grafting immunosuppression that includes high-dose cyclophosphamide and 
MMF, evaluate the safety and feasibility of reduced-duration  immunosuppression (from Day 5 
through Day 90 in cohort 1 and from Day 5 through Day 60 in cohort 2) compared to standard 
duration tacrolimus (From Day 5 through Day 180). 
 
2.2 
Secondary objectives 
1. In patients eligible for reduced-duration immunosuppression, estimate the incidences of severe 
acute grade III or higher GVHD, chronic GVHD (overall and by extent) requiring additional 
immunosuppressive therapy (IST), graft failure, relapse, and NRM between Days 90-180 for 
cohort 1 or Days 60-180 for cohort 2, and beyond Day 180. 
2. Estimate the cumulative incidence of severe acute grade III or higher GVHD, chronic GVHD 
(overall and by extent) requiring additional immunosuppressive therapy (IST), graft failure, 
relapse, and NRM for the group overall. 
3. Estimate the cumulative incidence of systemic steroid initiation, the cumulative incidence of non-
steroid immunosuppression use, and the cumulative incidence of discontinuation of systemic 
immunosuppression for GVHD treatment by 1 year and 2 years after HSCT for the group overall

and for patients with shortened-duration immunosuppression; and describe the number and 
types of systemic immunosuppression used for GVHD treatment. 
4. Estimate the progression-free survival, disease-free survival, overall survival, GVHD-free relapse-
free survival, and chronic GVHD-free relapse-free survival after transplantation. 
5. Evaluate MDS cohort in relation to transplantation outcomes.

matched donor.  
a. The donor and recipient must be identical at least one allele of each of the following 
genetic loci: HLA-A, HLA-B, HLA-Cw, HLA-DRB1, and HLA-DQB1.  A minimum match of 
5/10 is therefore required for related donors, and will be considered sufficient evidence 
that the donor and recipient share one HLA haplotype.  Unrelated donors will be 10/10. 
2. Eligible diagnoses:  
a. Myelodysplastic syndrome (MDS) including chronic myelomonocytic leukemia [CMML] 
with at least one of the following poor-risk features: 
i. Poor-risk cytogenetics 
ii. IPSS score of INT-2 of greater 
iii. Treatment-related or secondary MDS 
iv. MDS diagnosed before age 21 
v. Progression on or lack of response to standard DNA-methyltransferase inhibitor 
therapy 
vi. Life-threatening cytopenias, including those requiring frequent transfusions

iii. No massive splenomegaly, defined as > 6 cm below the left costal margin 
c. T-cell PLL in PR or better prior to transplantation. Must also have < 20% of bone marrow 
cellularity involved by PLL (to lower risk of graft rejection). 
d. Interferon- or tyrosine kinase-refractory CML in first chronic phase, TKI-intolerant CML in 
first chronic phase, or CML in second or subsequent chronic phase

6. Adequate end-organ function as measured by: 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
11
a. Left ventricular ejection fraction  35% or shortening fraction > 25% 
b. Bilirubin ≤ 3.0 mg/dL (unless due to Gilbert’s syndrome or hemolysis), and ALT and AST 
< 5 x ULN 
c. FEV1 and FVC > 40% of predicted; or if unable to perform pulmonary function tests due 
to young age, oxygen saturation >92% on room air  
7. ECOG performance status < 2 or Karnofsky or Lansky score > 60. 
8. Not pregnant or breast-feeding. 
9. No uncontrolled infection.  
Note:  Infection is permitted if there is evidence of response to medication. Eligibility 
of HIV infected patients will be determined on a case-by-case basis.   
 
3.2 
Donor eligibility 
1. Donors must be either: 
a. HLA-haploidentical or HLA-identical relatives of the patient based on allele or allele group 
level typing as defined in Section 3.1.   
b. Unrelated donor who is a 10/10 match to the recipient as defined in section 3.1. 
2. Medically fit to and willing to donate 
3. Lack of recipient anti-donor HLA antibody 
Note: In some instances, low level, non-cytotoxic HLA specific antibodies may be 
permissible if they are found to be at a level well below that detectable by flow cytometry.  
This will be decided on a case-by-case basis by the PI and one of the immunogenetics 
directors. Pheresis to reduce anti-HLA antibodies is permissible; however eligibility to 
proceed with the transplant regimen would be contingent upon the success of the 
desensitization.  
4. Has not donated blood products to patient 
 
3.3 
Donor prioritization  
Donors will be prioritized in the following order:   
1. Fit to donate 
2. HLA-matched prioritized over HLA-mismatched prioritized over unrelated 
3. Lack of major ABO incompatibility  
In order of priority: 
 
 
a.   Compatible 
 
 
b.   Minor incompatibility 
 
 
c.   Major incompatibility  
4. CMV serostatus: CMV negative donor preferred, if the patient is CMV negative; CMV positive 
donor preferred, if the patient is CMV is positive. 
5. Avoidance of female donor for male recipient 
 
Other factors such as donor age and health history will be integrated into the donor selection process 
per standard practice and may be prioritized over HLA, ABO and CMV status.

REGISTRATION PROCEDURES 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
12
 
4.1 
Registration requirements  
Patients will be registered in the CRMS.  The following are additionally required: 
1. Signed and dated informed consent  
2. Patient eligibility checklist(s) 
 
A registration may be cancelled, provided that protocol treatment has not been begun.   
 
4.2 
Accrual goal 
The goal is to transplant 60 patients with 90 day duration of immunosuppression in cohort 1 (per 
Section 9.0). Sixty patients will be transplanted in order to identify at least 20 who are evaluable for 
the safety of day 90 immunosuppression cessation. Up to 5 additional patients may be transplanted 
to replace unevaluable patients (per Sections 4.1 and 5.286).   
 
The goal is to transplant 60 patients with 60 day duration of immunosuppression in cohort 2 (per 
Section 9.0). Sixty patients will be transplanted in order to identify at least 20 who are evaluable for 
the safety of day 60 immunosuppression cessation. Up to 5 additional patients may be transplanted 
to replace unevaluable patients (per Sections 4.1 and 5.286). 
 
Every effort will be made to recruit women and minorities to this study. 
 
5.0 
TREATMENT PLAN 
 
5.1   
Evaluations and procedures 
Required evaluations are designated in Section 7.0.   
 
5.2 
Transplantation regimen 
The preparative regimen in each case consists of fludarabine, Cy, and TBI, with posttransplantation 
high-dose Cy, MMF, and tacrolimus. Tacrolimus may be replaced by sirolimus for clinical reasons (e.g. 
nephrotoxicity or PRES). 
5.21 
Fludarabine 
Fludarabine 30 mg/m2/day (adjusted for renal function) is administered over a 30-60 minute IV 
infusion on Days –6 through –2 (maximum cumulative dose, 150 mg/m2). 
 
The body surface area (BSA) for fludarabine dosing is based on actual body weight.   
 
For decreased creatinine clearance (CrCl), fludarabine dosage is reduced as follows or by institutional 
standard: 
 
 
CrCl  40-69 mL/min, fludarabine = 24 mg/m2 
 
 
CrCl 20-39 mL/min, fludarabine = 20 mg/m2 
 
For patients > 18 years old, CrCl will be estimated by the Cockcroft Formula, based on ideal body 
weight (IBW):  
 
 
CrCl = (140 – age) x IBW (kg)   x   0.85 for females 
 
 
                       PCr x 72 
For patients <18 years old, CrCl will be estimated by the Schwartz equation: 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
13
Schwartz equation: CrCl (mL/min/1.73m2)= [length (cm) x k] / serum creatinine 
k = 0.45 for infants 1 to 52 weeks old 
k = 0.55 for children 1 to 13 years old 
k = 0.55 for adolescent females 13-18 years old 
k = 0.7 for adolescent males 13-18 years old 
A measured CrCl or a glomerular filtration rate may be substituted to determine CrCl. 
Fludarabine dosing is based on the last CrCl prior to the start of conditioning. The estimated CrCl on 
the day preceding start of conditioning may be used.  The fludarabine dose should be the same on 
Days -6 to -2, even if the creatinine changes.  However, adjustment in fludarabine dose due to 
creatinine changes during conditioning is permitted. 
             
 
5.22 
Pretransplantation cyclophosphamide  
Cy 14.5 mg/kg/day is administered as a 1-2 hour IV infusion on Days –6 and –5 after hydration.  Mesna 
11.6 mg/kg IV daily on Days –6 and –5 is not required, but may be given.   
 
Cy and mesna are dosed according to IBW, unless the patient weighs less than IBW, in which case 
dose drug according to actual weight.   
 
 
5.23  
Total body irradiation  
200 cGy TBI is administered in a single fraction on Day –1.  Radiation sources, dose rates, and 
shielding follow institutional practice.   
 
 
5.24 
Day of rest 
A day of rest, i.e. after preparative regimen completion and prior to peripheral blood stem cell 
infusion, is not routinely scheduled.  Up to two days of rest may be added in this window based on 
logistical considerations or clinically as indicated.  For one day of rest, fludarabine would be 
administered on Days –7 through –3, pretransplantation Cy on Day –7 and Day –6, and TBI on Day –
2.  For two days of rest, fludarabine would be administered on Days –8 through –4, 
pretransplantation Cy on Day –8 and Day –7, and TBI on Day –3. 
 
 
5.25  
Peripheral blood stem cell transplantation 
On Day 0, peripheral blood stem cells are infused. The target stem cell dose is between 2 x 10^6/kg 
and 10 x 10^6/kg (actual body weight) CD34+ cells.  Sample of the product to be infused will be sent 
for flow cytometry to determine the content of CD34+ and CD3+ cells.  Graft dose including total 
nucleated cells infused/kg, CD34+ cells infused/kg, and CD3+ cells infused/kg will be recorded. The 
maximum CD34+ cell dose is 10 x 10^6/kg. If more than 10 x 10^6/kg CD34+ stem cells are collected, 
the excess will be discarded and not administered to the patient. Up to two leukapheresis procedures 
may be performed to obtain the minimum CD34+ cell target. If, after two leukapheresis procedures, 
fewer than 2 x 10^6/kg CD34+ cells have been collected, a bone marrow harvest will be 
recommended and the patient will be taken off trial. 
 
The graft will not be manipulated to deplete T cells.  Processing for ABO incompatibility follows 
institutional practices.  Guidelines for peripheral blood stem cell infusion are established and outlined 
in the ABO compatible/minor mismatched allogeneic HSCT or the ABO incompatible allogeneic HSCT 
standing orders.

5.26 
Posttransplantation cyclophosphamide  
Hydration prior to and following Cy, management of volume status, and monitoring for hemorrhagic 
cystitis will follow institutional standards.  Mesna will be used with posttransplantation Cy as per 
institutional standards.   
 
Cy and mesna are dosed according to IBW, unless the actual body weight is less, in which case dose 
drugs according to actual body weight.   
 
Cy 50 mg/kg IV, over approximately 1-2 hours (depending on volume), is given on Day 3 
posttransplantation (ideally between 60 and 72 hours after marrow infusion) and on Day 4 
(approximately 24 hours after Day 3 Cy).   
 
It is crucial that no systemic immunosuppressive agents are given from Day 0 until at least 24 hours 
after the completion of the posttransplantation Cy.  This includes corticosteroids as anti-emetics.  
 
5.27 
Mycophenolate mofetil  
MMF begins on Day 5, at least 24 hours after completion of posttransplantation Cy.  The MMF dose 
is 15 mg/kg PO TID (actual body weight) with total daily dose not to exceed 3 grams (i.e. maximum 1 
g PO TID).  Doses are rounded to the nearest strength tablets.  Equivalent IV dosing (1:1 conversion) 
may instead be given.  Guidelines for dose modification are provided in Section 8.15. MMF 
prophylaxis is discontinued after the last dose on Day 35, or may be continued if there is GVHD.  
 
5.28 Sirolimus or Tacrolimus 
 
5.281 Immunosuppression initiation and dosing 
Sirolimus OR tacrolimus begins on Day 5, at least 24 hours after completion of 
posttransplantation Cy. 
Duration of immunosuppression is designated in Section 5.282. 
 
For patients > 18 years old, the sirolimus starting dose is 6mg loading dose followed by 2mg 
daily or as per institutional standards. The tacrolimus starting dose is 2 mg PO BID or as per 
institutional standard. Patients who cannot tolerate PO may be started IV and changed to 
PO as per institutional standard. Dose is adjusted to maintain a serum trough level of 10 – 
15 ng/mL, with a minimum acceptable trough level of 5 ng/mL. 
 
For patients < 18 years old, the starting dose of tacrolimus is 0.015 mg/kg IV Q12 hours or 
as per institutional standard and is based on IBW unless the actual body weight is less. 
Tacrolimus can be changed to a PO BID dosing schedule once a stable therapeutic level is 
achieved and the patient can tolerate PO medications. Dose is adjusted to maintain a 
serum trough level of 10 – 15 ng/mL, with a minimum acceptable trough level of 5 ng/mL. 
 
In the case of prohibitive toxicities to calcineurin inhibitors (e.g., PRES), other 
immunosuppression may be given after case-by-case discussion with the PI or co-PI.   
 
5.282 Duration of immunosuppression 
The duration of immunosuppression is assigned prospectively in cohorts of patients before 
initiation of the preparative regimen. Immunosuppressionto Day 90 or Day 60 will be 
compared to Day 180.  Immunosuppression is stopped without taper. The same applies to 
sirolimus/ tacrolimus if the patient was switched. Patients who are switched will be 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
15
evaluated the same regardless of timing of switch as long as full criteria are met to stop 
immunosuppression on Day 90 in cohort 1 or Day 60 in cohort 2.  
 
 
Eligibility for protocol-driven, early immunosuppression discontinuation is provided in 
Section 5.283.  All of these eligibility criteria must be met in order to stop 
immunosuppression at the prespecified time point.   
 
In patients ineligible for protocol-specified early immunosuppression cessation, 
immunosuppression is discontinued after the last dose on Day 180 without taper; however 
in these patients, immunosuppression may be continued beyond Day 180 if GVHD has 
occurred or may be discontinued earlier in the context of relapse, progression, graft failure, 
or prohibitive toxicity.  Patients with suspected graft failure should remain on 
immunosuppression until at least the ~Day 56 chimerism assessment, although earlier 
discontinuation is permissible after discussion with the PI or co-PI.  
 
5.283 Eligibility for protocol-driven, early cessation of tacrolimus or sirolimus 
In order to be eligible for protocol-specified shortened-course immunosuppression, patients 
must meet all of the following criteria by the scheduled date of immunosuppression 
cessation by cohort 1 or 2:  
a. No documented graft failure 
b. Presence of at least 5% donor T cell chimerism in peripheral blood and/or bone  
marrow at ~Day 56 evaluations and beyond 
c. No acute, clinical grade II-IV GVHD, whether active or resolved 
Note: Eligible patients with acute grade I GVHD by the time of scheduled 
immunosuppression discontinuation will stop agent early as planned. 
d. No chronic GVHD, whether active or resolved, with the exception of 
asymptomatic or minimally symptomatic chronic GVHD limited to the oral 
mucosa.  
e. No documented disease progression or relapse 
f. No receipt of prohibited preemptive posttransplantation therapy (per Section 
5.4) or of unplanned therapy for persistent disease 
 
Evaluations that are required before the protocol-driven, early cessation of 
immunosuppression are provided in Section 7.0.  Early cessation of immunosuppression 
when required evaluations for eligibility are pending is discussed in Section 5.284.   
 
5.284 Early immunosuppression cessation in the context of pending evaluations  
If results of scheduled evaluations are pending at the time immunosuppression is due to stop 
early, immunosuppression should be stopped according to schedule and the duration of 
immunosuppression reevaluated when results become available.  
 
For logistical reasons, stopping immunosuppression up to 5 days after the scheduled stop 
date is permissible in patients for whom early, protocol-specified immunosuppression 
cessation is planned. 
 
Stopping immunosuppression more than 5 days later than the scheduled stop date 
constitutes a protocol deviation and is further discussed in Section 5.286. 
 
5.285 Changes in planned immunosuppression duration 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
16
If a patient begins study treatment but, prior to the planned immunosuppression 
discontinuation date, the target number of patients have been evaluated for safety or 
stopping criteria are met, the assigned immunosuppression duration for that patient may 
be changed as appropriate.   
 
5.286 Evaluability for the primary endpoint 
For protocol-driven, early cessation of immunosuppression, stopping immunosuppression up 
to 5 days after the scheduled stop date is permissible for logistical reasons.  Such patients 
will be considered evaluable for both the safety and feasibility of early immunosuppression 
cessation. 
 
Patients who should stop immunosuppression within this time frame (per protocol-driven 
criteria), but do not for logistical reasons, are unevaluable for safety; whether they remain 
evaluable for feasibility depends on the cause.  If immunosuppression is not stopped in the 
allowable window because of pending evaluations, feasibility will be based on the results of 
those evaluations, provided they were done no later than 5 days past the pre-specified date 
of immunosuppression cessation. Cases in which eligible patients do not stop 
immunosuppression early because of physician discretion will count against feasibility.    
 
Patients who are not evaluable for the primary endpoint may, if needed, be replaced but will 
continue on study unless consent is withdrawn. 
 
5.29 
Growth factors 
GCSF (filgrastim) begins on Day 5 at a dose of 5 mcg/kg/day (actual body weight) IV or subcutaneously 
(rounding to the nearest vial dose is allowed), until the absolute neutrophil count (ANC) is ≥ 
1,000/mm3 over the course of three days.  Additional GCSF may be administered as warranted.  
Pegfilgrastim (Neulasta®) and GM-CSF are not permitted. 
 
5.3 
Supportive care  
Patients will receive transfusions, nutritional support, infection prophylaxis and treatment, and other 
supportive care according to standard of care and institutional guidelines.  
 
5.31 
Anti-ovulatory treatment 
Menstruating females should begin an anti-ovulatory agent before starting the preparative regimen. 
 
5.32 
Intravenous access 
 
A central venous catheter is required for administration of IV medications and blood products. 
 
5.33 
Infection prophylaxis  
Patients will receive infection prophylaxis and treatment according to institutional guidelines.  
Infection prophylaxis should include agents or strategies to prevent herpes simplex, CMV, 
Pneumocystis jirovecii, fungal infections, and infections from oral flora secondary to mucositis.   
 
Posttransplantation immunizations will be given per institutional standard. 
 
5.34  Antiemetics 
Note that steroids should not be used as an antiemetic agent after the graft is infused, until at least 
24 hours after the completion of all posttransplantation Cy. The use of steroids as antiemetics after 
this time frame is discouraged in the absence of relapsed/progressive disease. 


Version 9.0 date: 11/14/2017 
IRB00080399

5.4 
Posttransplantation therapies 
 
5.41 
Donor lymphocyte infusion (DLI) 
Prophylactic posttransplantation DLI (e.g., for persistent detectable malignancy, prophylaxis in the 
absence of detectable malignancy, or mixed donor chimerism) is not permitted before Day 200, as 
this carries a high risk of GVHD.  The use of DLI will be recorded and such patients will be censored 
for analysis of disease and graft failure outcomes, GVHD, and related transplant-related toxicity 
outcomes.  Analysis of outcomes without such censoring is also planned. 
 
5.42 
Posttransplantation systemic therapy 
Preemptive systemic chemotherapy or biologic therapy (e.g., hypomethylating agent for MDS, 
tyrosine kinase inhibitor for Philadelphia chromosome-positive malignancy) is permitted after 
transplantation. Intrathecal chemotherapy is permitted.   
 
5.43 
Posttransplantation radiation 
Consolidative radiation therapy is permitted after transplantation. 
 
The use of preemptive therapy will be recorded. Patients who receive such therapies will not be 
censored for analysis of disease outcomes at that time, except as stated in Section 5.41.  
 
5.5 
Posttransplantation follow-up 
Required evaluations are designated in Section 7.0. 
 
More frequent monitoring of disease status, vital status, and toxicities may be performed for study 
purposes including through collection of outside records and patient and physician contact.  Patients 
who relapse or progress will continue to be followed on study unless consent is withdrawn.   
 
Patients will be followed primarily at Johns Hopkins at least until the ~ Day 56 evaluations, then 
periodically thereafter as designated in Section 7.0.  In the event that it is not possible or practical 
for a patient to come back to Johns Hopkins for required evaluations, clinical and laboratory 
evaluations performed though a local oncologist may fulfill study requirements. This will be decided 
on a case-by-case basis by the PI or co-PI; however chimerism assessments must be performed at 
Johns Hopkins.

Hematologic parameters 
 
 
 
6.11 
Neutrophil recovery: Post-nadir ANC > 500/mm3 for three consecutive measurements on 
different days.  The first of the three days will be designated as the day of neutrophil 
recovery.   
 
6.12 
Platelet recovery:  Sustained platelet count > 20,000/mm3 or > 50,000/mm3 with no platelet 
transfusions in the preceding seven days.  The first of three consecutive measurements on 
different days will be designated as the day of initial platelet recovery.  
 
 
6.13 
Donor chimerism: Mixed donor chimerism is defined as > 5%, but < 95%, donor.  Full donor 
chimerism is defined as > 95% donor.  


Version 9.0 date: 11/14/2017 
IRB00080399

Prior to transplantation, a sample of peripheral blood from the patient, and either harvested 
peripheral blood stem cells or blood from the donor, are collected for genetic studies to 
establish a baseline for subsequent chimerism assays.   
 
Chimerism determinations from T cells (CD3+ sorted) and whole blood (total nucleated cells) 
will be made from peripheral blood per Section 7.0, and more frequently as indicated.  
Methods may include (i) PCR analysis of variable number of tandem repeats (VNTR) in PBMC 
if informative, (ii) restriction fragment length polymorphism (RFLP) if the donor and recipient 
RFLPs are informative, (iii) fluorescence in-situ hybridization (FISH) for Y-chromosome 
markers on PBMC if the donor is male and patient is female, (iv) cytogenetic analysis, (v) flow 
cytometric analysis of HLA-A, B or DR on lymphocytes in the peripheral blood if haploidentical 
and suitable reagents exist.  Chimerism may also be determined from the bone marrow. 
 
 
 
6.14 
Graft failure: < 5% donor chimerism in blood and/or bone marrow on ~Day 28 or after and 
on all subsequent measurements.   
 
Primary graft failure: < 5% donor chimerism in blood and/or bone marrow by ~ 
Day 56  
 
Secondary graft failure: achievement of > 5% donor chimerism, followed by 
sustained <5% donor chimerism in blood and/or bone marrow. 
 
< 5% donor T cell chimerism, but with > 5 % donor chimerism in total leukocytes, is not 
considered graft failure. 
 
6.2 
Graft-versus-host disease 
 
6.21 
Acute GVHD:  Acute GVHD is graded by standard criteria (Appendix).42 All suspected cases of 
acute GVHD must be confirmed histologically by biopsy of an affected organ (e.g., skin, liver, 
or gastrointestinal tract).  Date of symptom onset, date of biopsy confirmation of GVHD, 
maximum clinical grade, sites affected, and dates and types of treatment will be recorded.  
Dates of symptom onset of initial diagnosis of GVHD (even if non-severe) and grade III-IV 
GVHD will be recorded.   
 
The cumulative incidences of acute grade III-IV and grade III-IV GVHD will be determined 
through competing risk analysis.  Treatment of disease relapse/progression/persistence 
(with the exception of planned maintenance or consolidative therapy), graft failure, and 
death are considered competing risks for GVHD for study purposes.  In addition, GVHD will 
be reported with only graft failure and death regarded as competing risks. 
 
 
6.22 
Chronic GVHD:  Chronic GVHD is graded by both NIH consensus criteria43 and Seattle 
criteria.44  Date of onset, date of biopsy confirmation (if any), dates and types of treatment, 
and extent will be recorded. The cumulative incidence of chronic GVHD (overall and 
according to extent) will be determined through competing risk analysis.   
 
6.3 
Disease and survival endpoints 
 
6.31 
Progression-free survival (PFS): Interval from Day 0 to date of first objective disease 
progression or relapse, unplanned treatment for disease persistence, or death from any 
cause.  Patients without these failures will be censored at the last date they were assessed 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
19
and deemed failure-free.  Disease persistence in the absence of progression is not considered 
a PFS failure unless it leads to treatment.  
 
6.32 
Disease-free survival (DFS): Interval from Day 0 to date of first objective detection of disease 
persistence, progression or relapse, or death from any cause.  Patients without such failures 
will be censored at the last date they were assessed and deemed failure-free.  Disease 
persistence posttransplantation, followed by disappearance of detectable disease in the 
absence of treatment, is not considered a DFS failure.  
  
6.33 
Overall survival (OS): Interval from Day 0 to date of death from any cause or last patient 
contact.   
 
6.34 
Nonrelapse mortality (NRM): Death without evidence of disease progression or relapse. 
Relapse/progression is a competing risk for NRM.   
 
6.35 
Relapse or progression: Defined per the following response criteria:  
a. CLL: 2008 International Workshop criteria 45 
b. MDS: 2006 IWG criteria 46 
 
Designation of disease status in other histologies will also follow standard criteria.  NRM is a 
competing risk for relapse/progression. 
 
6.36 
Minimal residual disease (MRD): MRD is defined by the sole evidence of malignant cells by 
flow cytometry, FISH, PCR or other techniques, in absence of morphological or cytogenetic 
evidence of disease in blood or marrow. Since the frequency and sensitivity of testing for 
MRD are variable, evidence of MRD will not be sufficient to meet the definition of relapse or 
progression in this study, but will be captured in the case report forms along with data on 
changing management in response to MRD detection.  In Ph+ disease, PCR-only detectable 
disease posttransplantation is not considered a DFS or PFS failure for study purposes.  
 
 
6.37 
GVHD-related survival endpoints 
 
 
 
6.371 GVHD-free relapse-free survival (GFRFS): Interval from Day 0 to acute grade III-IV 
GVHD, systemic treatment of chronic GVHD, or PFS failure (per Section 6.31), 
whichever occurs first.  Patients without these failures will be censored at the last date 
they were assessed and deemed failure-free. 
 
6.372 Chronic GVHD-free relapse-free survival (cGFRFS): Interval from Day 0 to a chronic 
GVHD event (variably defined as either moderate or severe chronic GVHD, or systemic 
treatment of any chronic GVHD) or PFS failure, whichever occurs first. Patients without 
these failures will be censored at the last date they were assessed and deemed failure-
free.

a Baseline evaluations should occur < 1 month before initiation of conditioning therapy, with the exception 
of the following: cardiac and pulmonary evaluations may occur < 8 weeks prior, and the HLA typing and 
baseline studies for chimerism determinations may occur at any point prior. Results of evaluations performed 
before study entry as standard of care may be used for research purposes and to fulfill study requirements. 
b Demographics and baseline characteristics will be captured.  Characteristics to be recorded include: age, 
gender, race/ethnicity, performance status, disease type, remission status, prior treatments including prior 
transplantation and type, donor age, donor relationship to patient, donor gender, type of transplant (HLA-
matched or mismatched), CMV serostatus of patient and donor, ABO compatibility.   
c Patients should continue to follow-up at Johns Hopkins at least yearly on study, per institutional standard of care.  
Follow-up data may be captured more frequently for study purposes.  Data that will continue to be recorded beyond 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
21
1 year include disease status until first relapse/progression, vital status, major transplant-related toxicities, and 
GVHD.   
d At minimum, CBC/differential should also be performed twice a week from start of preparative regimen, 
until ANC is >1000/uL over course of 3 days, then weekly until 12 weeks posttransplantation, and periodically 
thereafter; those need not be captured in the CRF. 
e CMP includes: BUN, creatinine, sodium, potassium, chloride, AST, ALT, total bilirubin, alkaline phosphatase. At 
minimum, these should be performed weekly until 12 weeks posttransplantation, then periodically until off 
immunosuppression; those need not be captured in the CRF. 
f Infectious disease evaluations follow institutional standard of care.  Minimum evaluations are CMV IgG, HSV IgG, 
VZV IgG, hepatitis panel (Hep B surface antigen, Hep B core antibody, Hep C antibody), HIV antibody (unless known 
to be HIV positive).   
g Follow-up studies should include relevant cytogenetics and molecular markers to detect residual disease, i.e. repeat 
of studies found to be positive at baseline. 
h May be omitted if there is documented disease persistence, progression or relapse before scheduled assessment. 
i Include comparison of pre- and post-treatment scans with bidimensional measurements where relevant.  
j GVHD and other morbidity assessments are also standardly performed weekly at Johns Hopkins until at least ~Day 
60.  Results of these and subsequent assessments may be collected for research purposes.  Patients may be asked to 
complete GVHD questionnaires. 
k Day 84 and later CMP, chimerism, and GVHD evaluations may be omitted in patients with documented graft failure. 
CBC/differential, H & P, and morbidity assessment at these time points will be obtained. 
l May be omitted in patients who receive treatment for disease persistence, progression, relapse. The dates of 
treatment initiation and DLI will be recorded.

LABORATORY CORRELATES 
 
8.1 
Plasma-derived cell free DNA (cfDNA):  cfDNA released from malignant cells can be reliably 
detected in patients’ plasma and has been widely used in diagnosis, early detection and 
disease burden monitoring in several solid malignancies. Most ctDNA is primarily derived 
from hematopoietic tissue and plasma-derived ctDNA appears to be the most reliable marker 
of the disease burden. Thus, we will assess the patient-specific mutations burden (minimal 
residual disease – MRD) at baseline and longitudinally post-HSCT. We will then correlate the 
ctDNA-based MRD Adetection with clinical outcomes. Somatic mutations will be assessed 
using the SureSelect Target Enrichment System (Agilent). The captured samples will be then 
sequenced on a HiSeq25000 (Illumina) using a 2x150 bp protocol. Data will be analyzed using 
our custom variant calling pipeline.

RISKS AND REPORTING REQUIREMENTS 
 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
22
9.1 
Drug information 
 
9.11  
Cyclophosphamide (Cytoxan®) 
Cyclophosphamide is an alkylating agent whose metabolites form cross-links with DNA resulting in 
cell cycle-nonspecific inhibition of DNA synthesis and function.  Cyclophosphamide side effects 
include: nausea, vomiting, diarrhea, headache, dizziness, hemorrhagic cystitis, fluid weight 
gain/edema, SIADH, transaminitis, cardiomyopathy, pericarditis, rash, mucositis, alopecia, 
cytopenias, sterility, and rarely, secondary myelodysplastic syndrome and anaphylaxis. 
 
Dose adjustments for cyclophosphamide will not be made. 
 
9.12  
Mesna (sodium-2-mercapto ethane sulphonate) 
Mesna is a prophylactic agent used to prevent hemorrhagic cystitis induced by the 
oxasophosphorines (cyclophosphamide and ifosphamide).  It has no intrinsic cytotoxicity and no 
antagonistic effects on chemotherapy.  Mesna binds with acrolein, the urotoxic metabolite produced 
by the oxasophosphorines, to produce a non-toxic thioether and slows the rate of acrolein formation 
by combining with 4-hydroxy metabolites of oxasophosphorines. 
 
The total daily dose of mesna is equal to 80% of the total daily dose of cyclophosphamide. 
At the doses used for uroprotection, mesna is virtually non-toxic.  However, potential adverse effects 
include nausea and vomiting, diarrhea, abdominal pain, altered taste, rash, urticaria, headache, joint 
or limb pain, hypotension, and fatigue. 
 
9.13 Fludarabine (Fludara) 
Fludarabine is a purine analog antimetabolite.  Side effects of fludarabine include: 
a. Neurotoxicity: Agitation or confusion, blurred vision, loss of hearing, peripheral neuropathy or 
weakness have been reported.  Severe neurologic effects, including blindness, coma, and death 
may occur; severe CNS toxicity is rarely seen with doses in the recommended range for 
nontransplant therapy. The dose used in this study is approximately 1.5 times the usual one-
course dose given in non-transplant settings.  Doses and schedules similar to those used in this 
study have been used in adult and pediatric patients without observed increase in neurotoxicity. 
 
b. Anemia: Life-threatening and sometimes fatal autoimmune hemolytic anemia has been reported 
after one or more cycles of therapy in patients with or without a previous history of autoimmune 
hemolytic anemia or a positive Coombs’ test and who may or may not be in remission.  
Corticosteroids may or may not be effective in controlling these episodes.  The majority of 
patients re-challenged developed a recurrence of the hemolytic process.  
 
c. Cardiovascular: Deep venous thrombosis, phlebitis, transient ischemic attack, and aneurysm (1%) 
are reported.    
 
d. Fever: 60% develop fever. 
 
e. Rash: 15% develop a rash, which may be pruritic.  
 
f. Digestive: Gastrointestinal side effects include: nausea/vomiting (36%), diarrhea (15%), 
stomatitis (9%), anorexia (7%), GI bleeding and esophagitis (3%), mucositis (2%), liver failure, 
abnormal liver function test, constipation, dysphagia (1%) and mouth sores.  
 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
23
g. Some other effects include: Chills (11%), peripheral edema (8%), myalgias (4%), osteoporosis 
(2%), pancytopenia, arthralgias (1%), dysuria (4%), urinary tract infection and hematuria (2%); 
renal failure, abnormal renal function test, and proteinuria (1%); and, very rarely, hemorrhagic 
cystitis and pulmonary toxicity.  
 
Dose adjustments of fludarabine are required for renal insufficiency (see Section 5.21). 
 
9.14 
Total Body Irradiation (TBI) 
TBI can cause: nausea and vomiting, diarrhea, parotitis (rapid onset within 24-48 hours, usually self-
limited), generalized mild erythema (usually within 24 hours, resolving in 48-72 hours) , 
hyperpigmentation, fever, mucositis, alopecia, and pancytopenia. Late effects include: cataracts (10-
20%), 
hypothyroidism, 
nephropathy, 
interstitial 
pneumonitis, 
veno-occlusive 
disease, 
carcinogenesis, and sterility.  
 
9.15 
Mycophenolate Mofetil (MMF, Cellcept®) 
MMF is an ester prodrug of the active immunosuppressant mycophenolic acid (MPA).  
Side effects include: pancytopenia, infection (including sepsis, CMV, HSV, VZV, and Candida), nausea, 
vomiting, diarrhea, allergic reactions, hypertension, headache, dizziness, insomnia, hyperglycemia, 
electrolyte imbalances, rash, and leg cramps/bone pain.  
 
Drug interactions: MMF activity is decreased with oral antacids and cholestyramine. There are no 
pharmacokinetic interactions with cotrimoxazole, oral contraceptives, or cyclosporine.  Acyclovir or 
ganciclovir blood levels may increase due to competition for tubular secretion. High doses of 
salicylates or other highly protein-bound drugs may increase the free fraction of MPA and exaggerate 
the potential for myelosuppression. 
 
Dose adjustments: No dose adjustments are required for liver dysfunction.  For renal insufficiency, 
MMF dosing should not be modified unless dialysis is needed, in which case MMF can be reduced to 
25-50% of the starting dose. 
 
9.16 
Tacrolimus (FK-506, Prograf®) 
Tacrolimus is a macrolide immunosuppressant that inhibits lymphocytes through calcineurin 
inhibition.   
 
Toxicities: There is a spectrum of well-described toxicities of tacrolimus. Toxicities include renal 
insufficiency, hypertension, hyperglycemia, hypomagnesemia, hypokalemia, nausea, diarrhea, 
headache, neurologic toxicity including tremor and leukoencephalopathy, infection, and rarely 
thrombotic thrombocytopenic purpura (TTP). 
 
Drug interactions: Tacrolimus is well absorbed orally.  Tacrolimus is extensively metabolized by the 
cytochrome P-450 (CYP3A4) system and metabolized products are excreted in the urine.  Drugs that 
may increase tacrolimus levels include tri-azole drugs (especially voriconazole and posaconazole), 
nephrotoxic drugs, calcium channel blockers, cimetidine and omeprazole, metoclopramide, 
macrolide antibiotics, quinupristin/dalfopristin, danazol, ethinyl estradiol, methylprednisolone, and 
HIV protease inhibitors.  Drugs that may decrease tacrolimus levels include some anticonvulsants 
(phenobarbital, phenytoin, carbamazepine), caspofungin, rifamycins, and St. John’s wort.   
 
Dose adjustments: The tacrolimus dose is adjusted to maintain a serum trough level of 5-15 ng/mL, 
with a target of 10-15 ng/mL.  Patients with hepatic or renal insufficiency should receive doses at the 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
24
lower end of therapeutic concentrations.  No dose adjustments are required in patients undergoing 
hemodialysis. 
 
Due to extreme interactions with voriconazole and posaconazole, the tacrolimus dose 
should be empirically lowered when these azoles are initiated at steady state levels of tacrolimus.  
Guidelines are provided in the table below section 8.17.  Dose adjustments for therapy with other 
azoles may be indicated.  However, the initial tacrolimus dose (on Day 5) remains fixed.  
 
9.17  Sirolimus 
Sirolimus is an immunosuppressant that inhibits cytokine-stimulated T-cell activation and 
proliferation, and also inhibits antibody formation.   
 
Drug formulations: The mean bioavailability of sirolimus after administration of the tablet is ~27% 
higher than the oral solution. Sirolimus oral tablets are not bioequivalent to the oral solution. 
Clinical equivalence has been demonstrated at the 2-mg dose level; however, it is not known if 
higher doses are clinically equivalent on a mg to mg basis. 
a) Sirolimus oral solution: Sirolimus oral solution (1 mg/mL) should be stored protected from 
light and refrigerated at 2°C to 8°C (36°F to 46°F). For dilution, the appropriate dose should 
be measured using an amber oral syringe, then added to a glass or plastic container that 
holds at least 60 mL.  Before taking the dose, it should be diluted with water or orange juice 
then taken immediately; it should not be diluted with grapefruit juice.  The syringe should be 
discarded after one use.  Sirolimus oral solution provided in bottles may develop a slight haze 
when refrigerated, which does not affect product quality; allow the product to stand at room 
temperature and shake gently until the haze disappears.  
b) Sirolimus tablets: Sirolimus tablets are available in 1 mg and 2 mg tablets that cannot be 
crushed or broken. Sirolimus tablets should be stored at 20° to 25° C (68°–77°F), protected 
from light. 
 
Toxicities: The most common adverse reactions of sirolimus are: peripheral edema, 
hypertriglyceridemia, hypercholesterolemia, hypertension, increased creatinine, constipation, 
abdominal pain, nausea, diarrhea, headache, fever, urinary tract infection, anemia, 
thrombocytopenia, arthralgia, pain. Adverse reactions that have resulted in rates of sirolimus 
discontinuation >5% were increased creatinine, hypertriglyceridemia, and thrombotic 
thrombocytopenic purpura (TTP) / thrombotic microangiopathy (TMA).  Sirolimus toxicities are 
summarized in the table below:

combination was noted.68  
c Lipid-lowering agent may be required; consider if fasting serum triglycerides are > 2.5 x ULN, and 
recommend starting if > 800 mg/dL. 
 
Drug interactions: Sirolimus is known to be a substrate for both cytochrome CYP3A4 and P-
glycoprotein.  Agents that may increase sirolimus levels include tri-azole drugs (especially 
voriconazole and posaconazole*), amiodarone, calcium channel blockers, macrolide antibiotics (but 
not azithromycin), micafungin, gastrointestinal prokinetic agents (cisapride, metoclopramide), 
cimetidine, cyclosporine, grapefruit juice, and HIV protease inhibitors. Agents that may decrease 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
26
sirolimus levels include anticonvulsants (carbamezepine, phenobarbital, phenytoin), rifamycins, St. 
John’s Wort.  
 
Dose adjustments: The sirolimus dose is adjusted to maintain a serum trough level of 5-12 ng/mL.  
Changes in levels due to altered bioavailability should be apparent within 24-48 hours.  For 
sirolimus without CNI as in this study, a 20-25% reduction of sirolimus dose is recommended for 
trough levels >12 – 18 ng/mL, and a 20-25% increase is recommended for trough levels < 5 ng/mL. 
Renal failure does not affect the excretion of sirolimus. Excretion is reduced in liver failure; 
impaired hepatic function should prompt consideration of reduction in sirolimus maintenance 
doses but no dose adjustment of the loading dose is necessary. 
Due to extreme interactions with voriconazole and posaconazole, these drugs are 
relatively contraindicated during sirolimus therapy. Sirolimus dose is to be reduced by 90% when 
voriconazole is initiated and should also be significantly reduced with posaconazole. Dosing 
guidelines are provided in the table below. 
 
Dosing considerations with concurrent azole therapy: Triazole antifungal medications are expected 
to increase serum CNI levels; therefore dosages of CNI’s should be adjusted accordingly. Guidelines 
are provided in the table below.  Of note, reversal of azole-mediated inhibition of CYP3A4 (and 
others) and P-glycoprotein is gradual when azoles are stopped.  Therefore, immediate significant 
dose increases in tacrolimus and sirolimus are not advised when azoles are stopped. Rather, dose 
increases should be cautious and based on more frequent monitoring of levels as appropriate.

9.2 Toxicity grading 
Toxicities are graded using the NCI’s Common Terminology Criteria for Adverse Events (CTCAE) 
Version 4.0. (http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm) 
 
9.3 Toxicity reporting 
The agents being used in the study are used extensively in the HSCT setting and have well-defined 
toxicity profiles.  In addition, there are many expected toxicities of allogeneic HSCT.  The following 
are examples of toxicities that are serious but not unexpected: Grade 4 cytopenias; neutropenic fever 
and sepsis; bacterial, fungal, or viral (including CMV, BK virus) infection; severe mucositis; severe 
GVHD; hepatic veno-occlusive disease; pulmonary toxicities; hemorrhagic cystitis; bleeding without 
hemodynamic compromise. 
 
For study purposes, the following will be recorded and reported in accordance with IRB 
requirements: 
a. Any hospitalization and its reason in the first year of transplant, with the exception of 
hospitalizations related to relapsed disease or second HSCTs. 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
27
b. Neutropenic fever is an expected, common complication; as such, hospitalizations for grade 
4 neutropenic fever will be reported in real-time to the IRB with hospitalizations for lesser 
grade neutropenic fever routinely reported on a yearly basis. 
c. Any death before Day 200, and any later death which is potentially transplant-related. 
d. Any unexpected, serious events deemed significant by the PI. 
 
 
In addition, the following toxicities will be tracked for study purposes and reported on a yearly basis 
to the IRB, or earlier if warranted:  
a. Clinically significant infections during the first year of transplant, with the exception of 
uncomplicated, culture-negative neutropenic fever. This includes CMV disease, other 
clinically significant documented viral infections, bacterial infections, and proven or probable 
invasive fungal infections. 
b. CMV reactivation (including asymptomatic reactivation) 
c. Hepatic veno-occlusive disease 
d. Grade 3 or greater pulmonary toxicity during the first year of transplant that is potentially 
transplant-related 
 
Additional complications and toxicities may be tracked. This is in addition to evaluating hematologic 
parameters, GVHD, and disease and survival endpoints outlined in Section 6.0.  
 
9.4 
Monitoring plan  
This is a Level I study under the SKCCC at Johns Hopkins Data and Safety Monitoring Plan.  The 
protocol will be monitored internally by the PI.  Data and safety monitoring oversight will be 
conducted by the SKCCC at Johns Hopkins Safety Monitoring Committee. An audit will be performed 
early in the study, and then audits will be performed periodically thereafter.   
 
9.5 
Risks and benefits   
Allogeneic HSCT carries risk for major morbidity and mortality.  Major toxicities and risks of the 
transplant procedure include acute and chronic GVHD, severe infection, immunosuppression which 
may be prolonged, graft failure, end-organ damage, and death.  High-dose posttransplantation Cy 
appears to significantly lower the risk of GVHD.  Shorter-duration immunosuppression may be 
associated with increased risk of GVHD, increased severity of GVHD, and graft failure. 
The potential benefits of this trial are palliation of disease-related symptoms and 
prolongation of overall or event-free survival, including the possibility of long-term disease-free 
survival and cure.  Potential benefits also include fewer infectious and other complications and lower 
risk of relapse because of the shorter duration of immunosuppression.

Primary endpoint and design 
 
Amendment 2/19/2017 
The interim analysis of the 90 day immunosuppression arm indicated that the shortened duration of 
tacrolimus/sirolimus was feasible and safe.  This amendment will further shorten the duration of 
immunosuppression to 60 days to determine if this is likewise feasible and safe.  The criteria for 
feasibility (threshold 33%) and safety (thresholds: 5% graft failure, 5% NRM, 50% relapse, and 10% 
combined grade III-IV acute GVHD and severe chronic GVHD) will be the same as those for the 90 day 
arm.  We evaluated the operating characteristics under similar scenarios that were used for the day 
90 arm of the study.  Historically, the cumulative risks of events between day 60 and 180 were: 2.7% 
for graft failure, 5.2% for NRM, 26.9% for relapse, and 5.0% for combined grade III-IV acute GVHD 
and severe chronic GVHD.  The prior for the day 60 arm will be based on the posterior for the 90 day 
arm, discounted by one half.   
 
Results of interim analysis: 
At the time of the interim analysis, the posterior probabilities of feasibility and the four event types 
being greater than their respective stopping criterion are given in the table below. The stopping rule 
declares the shortened duration of immunosuppression not feasible if there is 80% or more certainty 
that fewer than 33% of patients could have stopped tacrolimus/sirolimus early.  The stopping rule 
declares the duration of tacrolimus/sirolimus unsafe if the posterior probability is 67% or higher that 
the risk of that adverse event between the day tacrolimus/sirolimus stops and ~ Day 180 overly 
exceeds the following cause-specific probabilities: ≥ 5% graft failure, ≥ 5% NRM, ≥ 50% relapse, and 
≥ 10% combined grade III-IV acute GVHD and severe chronic GVHD.

Sample size:  Up to 60 patients will be transplanted in order to identify at least 20 who are evaluable 
for the safety of day 60 immunosuppression cessation.  Up to 5 additional patients may be 
transplanted to replace unevaluable patients.   
 
The primary goal of cohort 1 of this study is to determine whether one can shorten the duration of 
immunosuppression with tacrolimus or sirolimus to 90 days following nonmyeloablative, related or 
unrelated donor peripheral blood HSCT that incorporates high-dose posttransplantation Cy in 
patients with diagnoses that are difficult to engraft.   
 
This has been amended as above to include cohort 2 with the same goals for cessation of 
immunosuppression at Day 60.

To be relevant, an immunosuppression regimen must not only be safe, but be applicable to a 
sufficient number of patients.  Therefore, both safety and feasibility are incorporated in the primary 
analysis. Feasibility is herein defined as the proportion of patients, measured from Day 0, who meet 
criteria for protocol-driven, early immunosuppression cessation (as defined in Section 5.283) and 
have immunosuppression stopped at 90 days.  Monitoring rules for feasibility (based on the 
proportion of patients who are able to stop immunosuppression at day 90 and safety (i.e. 
complications do not exceed cause-specific thresholds defined below) will be implemented.  
 
It is possible that longer durations of immunosuppression are more safe (e.g., lower risk of GVHD), 
but less feasible (e.g., greater possibility of NRM or another event that would prevent protocol-driven 
early cessation of immunosuppression, as defined in Section 5.283).  Conversely, shorter durations 
of immunosuppression may be more feasible but unsafe (e.g., excessive GVHD).  Based on historical 
information, we expect that it will be feasible to reduce the duration of immunosuppression from 
the current standard (until Day 180) to until Day 90 or Day 60.  We hypothesize that stopping 
immunosuppression on Day 90 will not carry excess risk of GVHD or graft failure (potential 
manifestations of inadequate immunosuppression).  
 
10.11  Criteria for feasibility and safety 
This study considers it “feasible” to stop immunosuppression early (e.g., Day 90) if at least one-third 
(33%) of all evaluable transplanted patients have not had any of the events (defined in Section 5.283) 
that would render them ineligible to stop at day 90 or day 60 and who have immunosuppression 
stopped accordingly.  A Bayesian stopping rule will be implemented to declare a particular shortened 
duration of immunosuppression not feasible, if there is 80% or more certainty that fewer than 33% 
of patients could have immunosuppression stopped early.  The Bayesian rule begins with a Beta (3, 
3) prior probability distribution that immunosuppression until Day 90 is feasible. This prior 
distribution is based on historical information below and has mean 50% and 90% probability that the 
fraction of patients who will be available to have immunosuppression stopped is between 32% and 
68%.  Up to 65 patients will be transplanted in order to identify at least 20 who are evaluable for the 
safety of day 90 immunosuppression cessation.  Up to 5 additional patients may be transplanted to 
replace inevaluable patients (per Sections 4.1 and 5.286).  Patients who switch to sirolimus will be 
evaluated in the same fashion. 
 
Historical estimates were derived from 55 uniformly treated patients with diagnoses of hematologic 
malignancies that are hard to engraft (PLL, CLL, MDS, MPN, CML and CMML) treated with 
fludarabine/Cy/TBI conditioning, partially HLA-mismatched HSCT, posttransplantation high-dose Cy, 
MMF on Days 5-35, and tacrolimus on Days 5-180. Event-specific risks for graft failure, non-relapse 
mortality (NRM), relapse, and severe acute graft versus host disease (aGVHD) are shown in Table 1 
within 4 intervals: Days 1-60, 61-90, 91-120, and 121-180.  (Note that these probabilities are specific 
to the time interval indicated for each row and conditional on reaching the interval.)  The cumulative 
incidences of these events between day 90 and day 180 are <1%, 3.3%, 23.0%, and 5.9% 
respectively.

Separate stopping rules will be implemented for each of 4 events occurring between the date of 
immunosuppression discontinuation and the Day 180 evaluation (Day 180 evaluations are +/- 7 days 
for logistical reasons): a GVHD event specified below; graft failure; NRM; and disease relapse or 
progression.  For the stopping rules, the prior precision of these event-specific risks within each 
interval corresponds to a prior sample size of 15 patients, approximately one-fourth of the historical 
sample size of 55.  We discounted the historical data to avoid having the prior information dominate 
the inference from the current study’s data. 
 
The estimated historical cause-specific (cumulative) risks between Day 90 and 180 are 5.9% (GVHD), 
<1% (graft failure), 3.3% (NRM), and 23% (relapse).  For monitoring, we will compute the posterior 
probability of each of the four events, given the data and historical prior distribution, and evaluate 
whether to hold accrual after fixed cohorts of patients (per below).   
 
The stopping rule will declare a particular duration of immunosuppression unsafe if the posterior 
probability is 67% or higher that the risk of that adverse event between the day immunosuppression 
stops and ~ Day 180 exceeds the following cause-specific probabilities: stopping for > 10% combined 
incidence of acute, clinical grade III-IV (severe) GVHD and severe chronic GVHD, > 5% NRM, or > 5% 
graft failure in this window, or stopping for a > 50% incidence of disease relapse or progression in 
this window.   
 
Although chronic GVHD usually manifests later than Day 180, the window chosen for the primary 
monitoring rule is justifiable for several reasons:  a) In our haploidentical HSCT experience, the 
majority of patients who develop chronic GVHD will have had acute GVHD;24 b) A more extended 
observation window for stopping rule purposes would make timely completion of the trial difficult; 
and c) In the setting of myeloablative, matched, related or unrelated donor HSCT that utilizes high-
dose posttransplantation Cy as the sole agent for GVHD prophylaxis (i.e., no mycophenolate mofetil 
or CNI’s), the rate of chronic GVHD has been very low.35 
 
Patients who develop both acute and chronic GVHD will be regarded as having one adverse GVHD 
event for stopping rule purposes.  Patients who develop GVHD after treatment for relapse, 
progression/disease persistence (with the exception of maintenance or consolidative therapy) will 
be regarded as having a competing risk for GVHD.  The number of cases of acute grade III-IV occurring 
after treatment initiation for residual or relapsed/progressive disease will be reported.  
 
Monitoring will occur in groups of 5 assessable patients, beginning after the first 20 assessable 
patients have been transplanted and their immunosuppression stopped early at the prespecified 
time.  
 
In deciding upon the safety of a 90 day duration of immunosuppression, the nature of the stopping 
rule(s) met will be considered.  Excess GVHD or graft failure is a potential manifestation of inadequate 
immunosuppression, thus would lead one to favor a longer course of immunosuppression.  NRM may 
or may not be due to less immunosuppression; thus if only the NRM rate exceeds the predefined 
threshold, the recommended duration of immunosuppression will be contingent on the causes of 
NRM (whether they are unrelated or possibly related to reduced immunosuppression).  On the other 
hand, 
excess 
relapse/progression 
is 
not 
an 
expected 
manifestation 
of 
inadequate 
immunosuppression, since shorter-course or lower-dose CNI’s may lower the relapse risk.40,41 If only 
this stopping criterion is met, the length of time that the relapsed patients are evaluable for safety 
endpoints will be assessed and a decision rendered whether to increase the accrual goal.

It is possible that with the combined analysis of HLA-matched and HLA-mismatched transplants, an 
increased risk of graft failure, GVHD, or NRM with shortened-course immunosuppression, as 
compared to the historical outcomes with HLA-mismatched HSCT, may be less readily identified.  
However, most of the transplants will be HLA-mismatched, and the potential benefits to shortened-
duration immunosuppression are not specific to the type of transplant.  Inclusion of HLA matched 
transplants is justified because a) there will be continual monitoring for safety as described above; 
b) with postgrafting immunosuppression that includes high-dose Cy, our rates of graft failure and 
GVHD appear to be similar in the HLA-matched and -mismatched settings (Burroughs LM et al, BHSCT 
2008;14(11):1279-87),23 and c) with such postgrafting immunosuppression, increasing degrees of 
HLA mismatch have not been found to be associated with inferior outcomes in haploidentical HSCT 
(Kasamon YL et al, BHSCT16(4):482-9).34   
 
Amendment 2/19/2017 calculation of the prior for the 60 day immunosuppression arm:   
Using the stopping criteria for the 90 day arm of the study, events observed during the study were 
combined with the historical prior to calculate the posterior probability of adverse events in the 
chosen time intervals when stopping tacrolimus/sirolimus on day 90. This posterior, discounted by 
one-half, will be used as the prior for monitoring the current Day 60 data.  Event-specific risks for 
graft failure, NRM, relapse, and severe acute or chronic GVHD based on this prior are shown in the 
amended table within 4 intervals: Days 1-60, 61-90, 91-120, and 121-180.  (These probabilities are 
specific to the time interval indicated for each row and conditional on reaching the interval.)  The 
cumulative incidences of these events between day 60 and day 180 are <1%, 3 .8%, 16.5%, and 4.0% 
respectively.

10.12 Operating characteristics of design 
Simulation results reveal that these stopping rules perform well and provide reasonable protection 
of patients against unexpectedly elevated risks.  We carried out simulations of possible risks of each 
of four events among simulated groups of patients enrolling in the study.  The four events of interest 
are a) graft failure, b) relapse/progression, c) NRM, and d) GVHD.  We used historical information to 
derive a prior distribution for the risks of each of these four events within each of the following time 
intervals (days) following the transplant: 1-60, 61-90, 91-120, and 120-180.  Monitoring in groups of 
5 patients started after 20 patients entered the study.  Table 1. summarizes simulations of this design 
for historical risks, Table 1a, increased risks of each monitored event type, Table 1b, and increased 
risks and lower feasibility, Table 1c.  The risks in columns 2 through 5 are for the events being 
monitored in the day 90 to 180 interval during which immunosuppression is discontinued.  Columns 
7 and 8 give the percentage of time, out of 1,000 simulations, that the monitoring plan called for 
early stopping, either for safety, column 7, or feasibility, column 8.  Details of these simulations are 
provided in the Appendix.

10.2 Secondary endpoints 
 
a. In patients eligible for reduced-duration immunosuppression, estimate the incidences of acute 
grade II-IV GVHD, acute grade III or higher GVHD, chronic GVHD, graft failure, relapse, and NRM 
between the date of early immunosuppression cessation and Day 180, and beyond Day 180. 
Cumulative incidences of GVHD, relapse and NRM will be computed in these time frames 
using Fine and Gray’s method for competing risks.47,48  Treatment of disease 
relapse/progression/persistence, graft failure, and death are considered competing risks for 
GVHD; relapse/progression is a competing risk for NRM; and death before 
relapse/progression is a competing risk for relapse/progression. In addition, we plan to 
report GVHD incidences with only graft failure and death regarded as competing risks.  
 
The graft failure frequency in evaluable patients will be reported with 90% confidence 
intervals. 
 
Although historically, most cases of acute GVHD develop before Day 90 and graft failure after 
Day 60 is rare, the time course for these events in patients treated with less than 6 months 
of immunosuppression is not well defined.  The observation time for the primary safety 
monitoring rules varies according to immunosuppression duration, and it is possible though 
not expected that excess GVHD (acute or chronic), graft failure, or NRM will develop after 
Day 180.  Although these later-occurring events are not incorporated in the primary 
monitoring rule, their incidences will be continually monitored, and the trial will pause 
pending IRB review should these incidences appear prohibitive.  
 
These outcomes and the outcomes in points b through f below will be described with HLA-
mismatched and HLA-matched transplants combined, and individually where appropriate. 
 
b. Estimate the cumulative incidences of acute grade II-IV GVHD, acute grade III-IV GVHD, chronic 
GVHD, relapse and NRM for the group overall. 


Version 9.0 date: 11/14/2017 
IRB00080399 
 
34
The cumulative incidence of each of these events will be calculated from Day 0 using Fine 
and Gray’s method for competing risks.  
 
c. Estimate the cumulative incidence of systemic steroid initiation, the cumulative incidence of non-
steroid immunosuppression use, and the cumulative incidence of discontinuation of systemic 
immunosuppression for GVHD treatment by 1 year and 2 years after HSCT for the group overall 
and for patients with shortened-duration immunosuppression (i.e., for whom reduced duration 
immunosuppression was stopped at the assigned duration); and describe the number and types 
of systemic immunosuppression used for GVHD treatment. 
These cumulative incidences will be similarly estimated using competing-risk analyses, 
wherein graft failure and death, or graft failure, death and treatment of relapse/progression, 
are considered competing risks.  The number and types of systemic immunosuppression used 
for GVHD treatment will be reported descriptively. 
 
d. Estimate progression-free survival, disease-free survival, overall survival, and GVHD-related 
survival endpoints (GFRFS, cGFRFS) after transplantation. 
Using the Kaplan-Meier method, the probabilities of these survival endpoints at 1-year and 
longer-term will be estimated and reported with 90% confidence intervals. 
   
e. Describe the graft failure frequency, kinetics of neutrophil and platelet recovery, and kinetics of 
donor chimerism in unsorted and CD3+ sorted peripheral blood. 
The graft failure frequency in evaluable patients (those having chimerism results at least at 
~Day 28) will be described, with 90% confidence intervals.  Times to neutrophil and platelet 
recovery will be described with medians and ranges, and with cumulative incidence functions 
with death before count recovery as a competing risk.  The degree of donor chimerism in 
unsorted and CD3+ sorted peripheral blood at predefined time points (per Section 7.0) will 
be summarized with medians and ranges, and the proportion reaching full donor chimerism 
(total leukocyte, T cell)  by ~ Day 28 and ~ Day 56 will be estimated with 90% confidence 
intervals.  The proportion achieving >50% T cell donor chimerism at ~ Day 28 and ~ Day 56 
will similarly be estimated.   
 
The association between the amount of donor T cell chimerism at ~ Day 28 and patient/graft 
characteristics (e.g., prior therapies, graft cell dose) and transplantation outcomes (sustained 
engraftment, relapse or progression, GVHD) will be investigated.  Because of the limited 
sample size these investigations will be exploratory.   
 
 
f. Describe major toxicities and complications associated with the transplantation procedure.  
Selected toxicities will be reported descriptively. 
 
g. Evaluate selected MDS patients and transplant characteristics in relation to transplantation 
outcomes. 
 
The association between selected baseline patient and transplant characteristics and progression-
free survival, overall survival, relapse, and GVHD will be investigated using Cox proportional hazard 
models or proportional hazard models for competing risks

Statistical Supplement 
 
The following are details of the operating characteristics of the statistical design, with varying 
simulated risks, and planned cessation of immunosuppression on Day 90. In each scenario, 
the stopping criteria between Days 90 and 180 are as follows: Graft Failure = 0.05, 
nonrelapse mortality (NRM) = 0.05, relapse/progression = 0.50, GVHD (acute grade III-IV 
or severe chronic GVHD) = 0.10. Each scenario is shown with operating characteristics 
based on 1000 simulations.
