Enrollment: 51 participants; Allocation: NA; Intervention model: SINGLE_GROUP

Brief summary:
This is a phase 2 open-label trial designed to evaluate the efficacy of tildrakizumab in improving graft-versus-host disease (GVHD)-free relapse-free survival after myeloablative allogeneic hematopoietic cell transplantation (alloHCT) for hematologic malignancy.

Detailed description:
Study Rationale: GVHD remains a major cause of morbidity and mortality following myeloablative conditioning (MAC) alloHCT. Proinflammatory cytokines play a central role in initiation and development of acute GVHD and as such, inhibition of these cytokines has been examined for both prevention and treatment of GVHD. Interleukin (IL)-23 is a proinflammatory cytokine which the investigators' lab has shown to have a unique and selective role in induction of colonic inflammation during acute GVHD and that this cytokine serves as a critical mediator linking conditioning regimen-induced mucosal injury and endotoxin lipopolysaccharide (LPS) translocation to subsequent proinflammatory cytokine production and GVHD-associated pathological damage. Moreover, additional studies have demonstrated that blocking the IL-23 signaling pathway has not abrogated the graft-versus-tumor effect. Tildrakizumab is a commercially available anti-IL-23 antibody FDA approved for the treatment of moderate to severe psoriasis with good tolerance. The investigators hypothesize that blocking IL-23, with tildrakizumab, will reduce GVHD rates for patients undergoing MAC alloHCT without having an impact on relapse rates, thus improving GVHD-free relapse-free survival (GRFS).

Arms: arm 1: Tildrakizumab (IluymaTM) is a humanized monoclonal antibody that specifically binds to the IL-23p19 subunit of IL-23 to neutralize its function.
Interventions: intervention 1: Tildrakizumab
Intervention descriptions: intervention 1: 100 mg will be injected subcutaneously on Day -1, Day 28 ± 3, Day 112 ± 7, Day 196 ± 14, and Day 280 ± 14.

Study Rationale 
GVHD remains a major cause of morbidity and mortality following MAC 
alloHCT. Proinflammatory cytokines play a central role in initiation and 
development of acute GVHD and as such, inhibition of these cytokines has 
been examined for both prevention and treatment of GVHD. IL-23 is a 
proinflammatory cytokine, which our lab has shown to have a unique and 
selective role in induction of colonic inflammation during acute GVHD and 
that this cytokine serves as a critical mediator linking conditioning regimen-

induced mucosal injury and endotoxin lipopolysaccaraide (LPS) 
translocation to subsequent proinflammatory cytokine production and 
GVHD-associated pathological damage. Moreover, additional studies have 
demonstrated that blocking the IL-23 signaling pathway has not abrogated 
the graft-versus-tumor effect. Tildrakizumab is a commercially available anti-
IL23 antibody FDA approved for the treatment of moderate to severe 
psoriasis with good tolerance. We hypothesize that blocking IL23, with 
tildrakizumab, will reduce GVHD rates for patients undergoing MAC alloHCT 
without having an impact on relapse rates, thus improving GVHD-free 
relapse-free survival (GRFS).  
Primary 
Objectives 
Probability of GVHD-free relapse-free survival (GRFS). An event for this 
outcome is defined as either: 
x 
grade III–IV acute GVHD 
x 
systemic therapy requiring chronic GVHD 
x 
relapse 
x 
or death at 12 months  
after matched related/unrelated donor peripheral blood HSCT using 
myeloablative conditioning regimen.  
Primary 
Endpoint 
GVHD-free relapse-free survival (GRFS).  
Secondary 
Objectives 
1. Cumulative incidence of mild, moderate, and severe chronic GVHD,  
according to the NIH criteria, and limited or extensive GVHD by 
conventional criteria.  
2. Cumulative incidence of grade III–IV acute GVHD at days 100 and 
180. 
3. Probability of lower GI tract GVHD. 
4. Incidence of primary and secondary graft failure. 
5. Probability of non-relapse mortality (NRM) post HSCT.  
6. Cumulative incidence of relapse/progression of the primary 
malignancy.  
7. Probability of overall survival (OS) post HSCT.  
8. Assess the pharmacokinetic (PK) profile of multi-dose tildrakizumab. 
9. Incidence of infections. 
10. Donor cell chimerism. 
11. Effect of GVHD prophylaxis on gut microbiome diversity:  difference 
in the level of microbiome diversity during transplant and association 
of baseline gut microbiome diversity with development of aGVHD, 
cGVHD and overall survival. 
 
Secondary 
Endpoint(s) 
1. Chronic GVHD. 
2. Acute GVHD. 
o Grade II–IV. 
o Grade III–IV. 
3. Acute GI GVHD. 
4. Graft failure and hematopoietic recovery. 
5. Non-relapsed mortality (NRM). 
6. Disease relapse or progression.

Study Design 
This is a phase II open-label trial designed to evaluate the efficacy of 
tildrakizumab in improving GRFS after myeloablative allogeneic 
hematopoietic cell transplantation for hematologic malignancy.  
Study Agent/ 
Intervention 
Description 
Patients enrolled on this clinical trial will receive tacrolimus initiating at day -
3 at doses to maintain therapeutic levels per institutional preference and 
continued until at least day +90 post-transplant. Methotrexate will be 
administered intravenously and dosed at 15 mg/m2 days +1, and 10 mg/mg2 
on days +3, +6, and +11. Tildrakizumab will be administered 
subcutaneously at a dose of 100 mg on day -1, day 28 ± 3, day 112 ± 7, day 
196 ± 14, and day 280 ± 14. 
Number of 
Subjects 
55 patients 
Subject 
Participation 
Duration 
Patients will be followed for at least 12 months following alloHCT. 
Duration of 
Follow-up 
Patients will be followed for at least 12 months following alloHCT. 
Estimated Time 
for Study 
Completion: 
The study will reach study completion 30 months from the time the study 
opens to accrual. 
Statistical 
Methodology: 
The study will test the primary hypothesis that GRFS at 12 months exceeds

1  BACKGROUND 
Allogeneic hematopoietic stem cell transplantation (HSCT) is an intensive treatment modality that 
often represents the only curative therapy for patients with aggressive hematologic malignancies 
or other marrow failure syndromes. More than 8,000 allogeneic HSCTs were performed in the 
United States in 2016.1 Despite this, the procedure continues to carry a high morbidity and 
mortality rate. One of the principal contributors to transplant-related mortality is graft-versus-host 
disease (GVHD).2 GVHD develops in approximately 40– RI SDWLHQWV XQGHUJRLQJ DQ +/$
matched related HSCT and 50–RIUHFLSLHQWVUHFHLYLQJDPDWFKHGXQUHODWHGGRQRU+6&7. 3,4 
This is despite standard GVHD prophylactic medications administered to all transplant recipients. 
Once established, GVHD proves resistant to frontline therapies with corticosteroids in more than 
RISDWLHQWV,5 and survival is significantly diminished for these patients. 6,7 
 
1.1  Graft-versus-Host Disease 
 
GVHD is an immunological phenomenon whereby donor lymphocytes respond to host peptides 
expressed on polymorphic human leukocyte antigens (HLA) molecules. This results in a clinical 
syndrome which can be described as an inflammatory response directed predominantly against 
the skin, intestine, and liver. The interaction between donor lymphocytes and polymorphic HLAs 
on host tissues is amplified by the significant tissue damage that occurs in transplant recipients 
as a result of the conditioning regimen. This leads to a significant cytokine and chemokine 
signaling, which furthers this destructive cascade.  
 
GVHD has been divided into two phases, termed acute and chronic, which are distinguishable 
based on both temporal characteristics as well as unique clinical and pathological manifestation.8-
10 Acute GVHD (aGVHD) typically occurs in the first 100 days of transplant and targets a restricted 
set of organs including the skin, gastrointestinal (GI) tract, and liver, leading to cell apoptosis.11 
Chronic GVHD, alternatively, tends to occur after the first 100 days of transplant and can impact 
almost any organ system, with protean manifestations that have similarities to what occurs during 
autoimmune diseases.  
 
The pathophysiology underlying acute GVHD is often considered a “cytokine storm” with a three-
phase process:  (1) the conditioning regimen results in systemic inflammation due to release of 
pro inflammatory cytokines such as IL-1, IL-6, TNF-D, and INF-J; (2) donor T-cell priming and 
differentiation as a response to presentation by host antigens to APC;  (3) effector phase of tissue 
apoptosis mediated by inflammatory cytokines and T/NK cells effectors.2 
 
Compelling data in experimental models have shown that the GI tract plays a primary role in the 
amplification of acute GVHD.12,13 Damage to the gastrointestinal mucosa from the conditioning 
regimen results in the release of damage- and pathogen-associated molecular patterns (DAMPs 
and PAMPs),13,14 which activate cells of the innate immune system through the ligation of pattern 
recognition receptors (PRRs).15 This ultimately leads to the generation of clonally expanded 
alloreactive T cells, which mediate further damage, creating an inflammatory positive feedback 
loop. From a clinical perspective, involvement of the GI tract is a major cause of morbidity and 
can result in significant complications, including protracted diarrhea, requirement for parenteral 
nutrition, and infectious complications due to translocation of bacteria across a damaged mucosal 
barrier.16 Given the pivotal role that the GI tract plays in GVHD biology, strategies designed to 
reduce inflammation in this target organ have the potential to significantly decrease morbidity and 
mortality associated with this disease. 
 
Owing to the central role of proinflammatory cytokines in the initiation and development of acute 


 
 
 MCW Protocol No: PRO00035737 
20 
  Version No. 7 
 
 
Version Date: 10/31/2022 
graft-versus-host disease, inhibiting these cytokines has been looked at for both prevention and 
treatment of GVHD.  
 
1.2  Interleukin-23  
 
IL-23 is a member of the IL-12 family, signals through STAT3, and is secreted by dendritic cells 
(DCs), as well as other antigen presenting cells (APCs) such as macrophages and monocytes.i 
17 This cytokine shares a p40 subunit with IL-12, but also contains an IL-23-specific p19 
component. The p19/p40 complex binds to the IL-12RE1 subunit that is also a component of the 
IL-12 receptor along with a unique IL-23 receptor subunit that together is present on 
memory/activated T cells, DCs and macrophages.18 Early studies demonstrated that IL-23 plays 
a critical role in disorders such as experimental allergic encephalomyelitis (EAE),19 collagen-
induced arthritis,20 and inflammatory bowel disease21 implicating this cytokine as a pivotal 
mediator in the pathogenesis of inflammatory disorders and autoimmunity.  
 
1.3  IL-23 and GVHD 
 
Studies in our laboratory using preclinical murine bone marrow transplantation models have 
demonstrated that IL-23 has a unique and selective role in the induction of colonic inflammation 
during acute GVHD and serves as a critical mediator linking conditioning regimen-induced 
mucosal injury and lipopolysaccharide (LPS) translocation to subsequent proinflammatory 
cytokine production and GVHD-associated pathological damage.11,22 Specifically, transplantation 
of IL-23–deficient marrow grafts or administration of a p19-specific antibody significantly reduced 
the severity of acute GVHD, which was attributable to the preferential reduction in colonic GVHD, 
and a decrease in the production of proinflammatory cytokines within this tissue site. Secretion of 
IL-23 by donor, and not host, APCs was shown to be a critical event in the induction of GVHD of 
the colon. In subsequent studies, we identified that the proinflammatory effects of IL-23 were 
mediated through CD4+ T cells that expressed the IL-23 receptor.23 Specifically, these studies 
identified a unique colitogenic CD4+ IL-23R+ T-FHOOSRSXODWLRQWKDWFRQVWLWXWLYHO\H[SUHVVHVWKHȕ
integrin, CD11c, has a biased central memory phenotype and memory T-cell transcriptional 
profile, possesses innate-like properties by gene expression analysis, and has increased 
expression of the gut-KRPLQJ PROHFXOHV Įȕ DQG &&5. Adoptive transfer of these cells 
resulted in increased overall mortality, proinflammatory cytokine production and pathology 
specifically in the colon. Collectively, these findings defined a novel organ-specific role for IL-23 
in the pathophysiology of GVHD and demonstrated that IL-23 could direct tissue-specific 
pathology within the context of a systemic inflammatory disorder. Moreover, additional studies 
demonstrated that blockade of the IL-23 signaling pathway did not abrogate the graft-versus-
leukemia effect when tested in both acute and chronic models of leukemia.23 Thus, targeting the 
IL-23 pathway for GVHD prevention in murine models resulted in separation of GVH and GVL 
reactivity. Thus, with a series of publications in well-characterized mouse models, we believe that 
we have established that IL-23 has a pivotal role in the pathophysiology of GVHD in the GI tract. 
In addition, there have been a number of studies that have suggested that donors with IL23R 
polymorphisms which result in attenuated IL-23 secretion have a protective effect on the 
occurrence of moderate-to-severe acute GVHD in transplant recipients.24   
 
1.4  Tildrakizumab 
 
Tildrakizumab (IluymaTM) is a humanized monoclonal antibody that specifically binds to the IL-
23p19 subunit of IL-23 to neutralize its function.25 The drug has been evaluated in clinical trials 
for patients with moderate to severe psoriasis with good effect.25,26 The drug was well tolerated, 
with maximum-tolerated dose (MTD) of 10 mg/kg-1 once monthly. The responses were achieved 


 
 
 MCW Protocol No: PRO00035737 
21 
  Version No. 7 
 
 
Version Date: 10/31/2022 
at all dose level (0.05–10 mg/kg-1), maximum responses were achieved at dose level 3 and 10 
mg/kg-1.  
 
The most common adverse events reported were headache, nasopharyngitis, upper respiratory 
infection, and cough. There was no dose increase related adverse events. Among the serious 
adverse events reported was convulsion, which was attributed secondary to tildrakizumab, 
occurred 17 days after the 10 mg/kg-1 doses, but there were several reported confounding factors; 
alcohol consumption, lack of sleep and use of benzodiazepines. In terms of pharmacokinetic, the 
drug had slow systemic clearance with long half-life of around three weeks. Another significant 
finding of the study was that the IL-23p19 expression almost completely disappeared from the 
affected tissue after tildrakizumab treatment, suggesting that the drug possesses direct effect on 
IL-23 producing cells. Based on this data, tildrakizumab was FDA approved for treatment of 
moderate to severe plaque psoriasis in March 2018. 
 
1.5  Tildrakizumab and Treatment of GVHD 
 
To date, tildrakizumab has not been tested for prevention or treatment of GVHD but based on 
aforementioned data suggesting a pivotal role for IL-23 in the pathophysiology of GVHD, coupled 
with the very favorable safety profile of tildrakizumab; we propose to conduct a phase II study 
evaluating the efficacy of tildrakizumab plus standard immunosuppressive therapy in preventing 
GVHD in patients undergoing a myeloablative HSCT. The FDA approval for use of this agent in 
patients with plaque psoriasis, with a well-reported safety profile, justifies not embarking on a 
phase I study in this population. However, as we were well aware that patients undergoing MAC 
alloHCT patients represent a uniquely vulnerable patient population with potential for unexpected 
and potentially life-threatening adverse effects, we initially proposed a safety run-in phase of six 
patients to ensure these patients appropriately engrafted and did not experience any unexpected 
adverse events before proceeding to the full phase II study. 
 
 
1.6  Correlative Studies 
 
Given the known cytokine dysregulation that is seen in the setting of allogeneic HSCT, especially 
in acute GVHD,27 we intend to perform correlative studies to understand the impact of anti-IL-23 
antibody treatment on the proinflammatory cytokine milieu that is typically seen post-allogeneic 
HSCT. This testing may help us better understand the changes that are happening within the 
immune system to inhibit graft-versus-host disease (GVHD).  
 
1.7 Studies of the Microbiome in Transplant Patients 
 
The microbiome, consisting of a varied community of microbes (bacteria, viruses, fungi, 
microeukaryotes, and sometimes multicellular parasites), exists in niches across the human 
body. The skin, lung, nares, vagina, and gastrointestinal tract are among the most heavily 
colonized, with the largest number of microorganisms inhabiting the colonic lumen. While the 
majority of the over trillion organisms that live within a healthy human colon are nonpathogenic 
members of the phyla Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria, alterations 
in the balance of these microorganisms have been associated with adverse outcomes ranging 
from GVHD and infection to relapse post-HCT. 28 This clinical association between intestinal 
microorganisms and HCT outcomes has been investigated for decades and has informed the 
still controversial practices of infection prophylaxis, gut decontamination, the “neutropenic diet,” 
and isolation of patients in laminar air flow rooms. Single-institution studies have demonstrated 
that low microbial diversity in the stool after allogeneic HCT is associated with poor survival. 29,30 


 
 
 MCW Protocol No: PRO00035737 
22 
  Version No. 7 
 
 
Version Date: 10/31/2022 
Additionally, specific alterations have been associated with increased risk of acute GVHD, 
infectious outcomes and most recently, relapse. 31-33 While these findings are compelling, the 
generalizability of these proposed microbial biomarkers is unclear. This is particularly important 
as there is known geographic variation of the intestinal microbiome and practice variability in 
antibiotic use for prophylaxis and treatment from institution to institution, in part due to different 
antibiograms. 
 
Novel methods in microbiome research are likely to facilitate translational breakthroughs — 
these methods allow (1) detailed taxonomic classification of microorganisms at the strain level, 
(2) metabolic characterization of the small molecules and proteins that a microbial community 
makes, (3) measurement of microbial genomic evolution in clinical time courses, and (4) 
culturing of previously fastidious organisms from the microbiome for in vitro investigation and 
cultivation as potential therapeutic live bacterial clinical interventions. Given recent reports 
suggesting that alterations in the microbiome can impact the efficacy of immunologic therapies, 
it is imperative that the link between the microbiome and transplant outcomes is 
investigated.34,35  
 
 
1.7.1  Microbiome and Outcomes after Allogeneic Transplantation using Tildrakizumab as 
GVHD Prophylaxis 
The study will test the secondary hypothesis that the use of IL-23 blockage (tildrakizumab), 
which has been shown to lower gastrointestinal GVHD rates, preserves the gut microbiome 
diversity (determined by 16s rRNA sequencing analysis of the sequential stool sample collected 
pre- and post-transplant until neutrophil engraftment). Additional analyses on patient samples 
will be conducted to answer the key question concerning the impact of the gut microbiome on 
transplant outcome. Aliquots preserved additionally will establish a cohort of stool samples 
collected prospectively for future sequencing by shotgun metagenomic sequencing and 
metabolomic analysis. Previous GVHD prophylaxis studies performed at this institution have 
also evaluated microbiome diversity in this setting. Continuing these important exploratory 
evaluations will help to add to our knowledge base in this arena and will contribute importantly 
to future research. 
 
2  HYPOTHESIS, OBJECTIVES, AND ENDPOINTS 
In this study, we hypothesize that IL-23 inhibition through repeated treatment with tildrakizumab, 
when added to standard GVHD prophylaxis, will result in an improvement in GVHD-free 
relapse-free survival (GRFS) for adult patients undergoing a myeloablative allogeneic HSCT for 
hematologic malignancies.  
 
2.1  Primary Objectives 
The primary endpoint of this trial is to determine the probability of GVHD-free relapse-free survival 
(GRFS). An event for this outcome is defined as either grade III–IV acute GVHD, systemic 
therapy-requiring chronic GVHD, relapse, or death at 12 months after matched related/unrelated 
donor peripheral blood HSCT using myeloablative conditioning regimen. Patients who are alive 
without GVHD will be censored at the last follow-up.

12. Effect of GVHD prophylaxis on gut microbiome diversity:  difference in level of 
microbiome diversity during transplant and association of baseline gut microbiome 
diversity with development of aGVHD, cGVHD and overall survival. 
 
 
2.3  Rationale for the Outcome Measures Selection 
Ample evidence suggests that IL-23 has a pivotal role in the pathophysiology of GVHD and 
preclinical studies suggest that blocking the IL-23 pro-inflammatory pathway can prevent GVHD. 
In this study, we will treat patients with tildrakizumab, which is a humanized monoclonal antibody 
that specifically binds to the IL-23p19 subunit of IL-23. We hypothesize that targeting IL-23 will 
reduce the incidence of GVHD and improve morbidity and mortality after transplantation.  
2.4  Primary Endpoint 
The primary endpoint of this trial is GRFS. An event for this outcome is defined as grade III–IV 
acute GVHD, chronic GVHD requiring systemic therapy, relapse or death. Patients who are alive 
without GVHD will be censored at the last follow-up. 
2.5  Secondary Endpoint(s) 
1. Chronic GVHD 
The cumulative incidence of chronic GVHD by NIH Consensus criteria (Appendix 2) will 
be determined. Development of chronic GVHD will be considered an event for this 
endpoint. The highest grade of chronic GVHD will be recorded. In addition, the time of 
onset of chronic GVHD and the time to highest chronic GVHD grade will be recorded. 
Death but not disease relapse will be considered a competing event. 
 
 
2. Acute GVHD 
Cumulative incidences of grades II–IV and III–IV acute GVHD will be determined at day 
+100 and day +180 post-HCT. Acute GVHD will be graded according to Appendix 2. The 
time of onset of grade II–IV acute GVHD and time to development of the highest grade 
until day +180 will be recorded. Development of acute GVHD will be considered an event 
for this endpoint. Death but not disease relapse will be considered a competing event.

3. Graft failure 
Graft failure will be assessed as a secondary endpoint, including primary and secondary 
JUDIWIDLOXUH3ULPDU\JUDIWIDLOXUHLVGHILQHGDVQRQHXWURSKLOUHFRYHU\WR!FHOOVȝ/E\
day 28 post-HCT. Secondary graft failure will be assessed according to neutrophil count 
after initial hematologic recovery. Secondary graft failure is defined as initial neutrophil 
engraftment followed by subsequent decline in absolute neutrophil counts <500 FHOOVȝ/
unresponsive to growth factor therapy, but cannot be explained by disease relapse or 
drugs. 
 
4. Hematopoietic recovery 
Hematopoietic recovery will be assessed according to neutrophil and platelet counts 
recovery after HSCT. Neutrophil recovery or engraftment is defined as achieving an 
DEVROXWHQHXWURSKLOFRXQW$1&PP3 for three consecutive measurements on three 
different days. The first of the three days will be designated the day of neutrophil 
engraftment. The competing event is death without engraftment. Platelet recovery is 
defined by either the first day of a sustained platelet count >20,000/mm3 for three days 
with no platelet transfusion in the preceding seven days. The first day of sustained platelet 
count above these thresholds will be designated the day of platelet engraftment. 
 
5. Non-relapsed Mortality (NRM) 
NRM is defined as death after alloHCT without relapse. The cumulative incidence of NRM 
will be estimated at day +100 and one year after alloHCT. An event for this endpoint is 
death without evidence of disease progression or relapse. Disease progression or relapse 
will be considered a competing event. 
 
6. Disease Relapse or Progression 
Relapse is defined by either morphological, cytogenetic or radiologic evidence of the 
pretransplant hematologic malignancy. Institution of any therapy to treat persistent, 
progressive or relapsed disease, including the withdrawal of immunosuppressive therapy 
or donor lymphocyte infusion, will be considered evidence of relapse/progression. NRM 
will be considered a competing event. 
 
7. Progression-Free Survival 
The event for this endpoint is relapse/progression or death. The time to this event is 
measured from transplant to death or relapse/progression, whichever comes first. Patients 
who are alive and disease-free will be censored at last follow-up. 
 
8. Overall Survival 
The event for this endpoint is death from any cause. The time to this event is measured 
from the time of transplant to death from any cause or for surviving patients, to last follow-
up. Survivors will be censored at last follow-up. 
 
 
9. Pharmacokinetics and ADA/NAB testing 
Pharmacokinetic sampling will be performed by Sun Pharmaceutical Industries Ltd., 
which will outsource these samples to Labcorp Drug Development. Given the long half-
life of tildrakizumab, samples will be collected on week 0 (prior to administration of 
tildrakizumab), and then on days 30, 60, and 90. Each PK analysis draw requires five 
tubes of blood, each with 2–3 mL per tube, for a total of 10–15 mL of blood per PK 
analysis. PK samples should be stored at -70 degrees. Samples can be batched and 
shipped to Labcorp Drug Development. 


 
 
 MCW Protocol No: PRO00035737

  Version No. 7 
 
 
Version Date: 10/31/2022 
ADA testing is testing for anti-drug antibodies, while Nab testing is testing for neutralizing 
antibodies to give a more complete picture along with the PK testing. ADA testing 
typically includes 3 tiers- screen, confirm and titer where screen/confirm are qualitative 
(positive or negative) and titer is semi-quantitative. The Nab method for tildrakizumab is 
screen tier only and qualitative (positive or negative), in which only samples that test 
positive are confirmed in the ADA assay. The purpose of having ADA/Nab testing 
alongside the PK testing is to better understand the PK profile differences seen. For 
instance, if PK serum concentrations are lower for an individual then a high ADA 
response would provide more clarity regarding the serum levels. Nab testing then would 
give additional insight into the mode of action of the immunogenicity.  
 
10. Incidence of infections 
The incidence of grade  &7&$( Y5) viral, fungal, and bacterial infections will be 
determined. The cumulative incidence of CMV viremia post-alloHCT will be described. 
 
11. Donor cell chimerism 
Chimerism will be evaluated using sorted whole blood in CD3+ and CD33+ fractions. 
Mixed chimerism is defined as the presence of donor cells, as a proportion of total cells to 
EH!DQG)XOOGRQRUFKLPHULVPLVGHILQHGDVRIGRQRUFHOOV'RQRUFHlls

patients at day +28 (baseline) for both CD3+ and CD33+ fractions. The proportion of 
patients with each level of chimerism listed above will be described. CD3+ donor cell 
chimerism will be used to define the donor/recipient chimerism status. 
 
12. Microbiome 
To address this question, we will obtain stool samples from each patient prior to 
transplantation as a baseline and then at weekly intervals through the period of 
engraftment (defined as an absolute neutrophil count >500/mm3 for three consecutive 
days). In addition, stool samples will be obtained at the time of GVHD onset in any affected 
patients. Fresh fecal samples will be collected and immediately preserved in RNAlater 
solution to facilitate optimal sample preservation, consistency of sample quality and ease 
of sample transport. Genomic DNA will be isolated from 200 mg of fecal sample using the 
Qiagen Powerlyzer Powersoil® kit as described.40 Bacterial composition and abundance 
will be validated by quantitative PCR analysis. Composition of the microbiota will be 
determined through sequencing of the 16S rRNA gene V4 region (Diversigen, Baylor 
College of Medicine, Waco, TX). PCR products will be generated using a dual-indexing 
amplification strategy, then sequenced on the MiSeq platform (Illumina, San Diego, CA). 
  
RNA gene sequence data will be utilized for bioinformatic analysis. 16S primers will be 
removed from the Illumina reads with the Trimmomatic program. Paired-end sequences 
will then be assembled using the FLASH algorithm,42 and chimeric sequences will be 
removed using UCHIME.43 The remaining clean 16S sequences will be clustered into 
operational taxonomic units (OTUs) using the UPARSE pipeline.44 A sequence identity of

counts generated as described above. OTU counts will be converted to measures of 
relative abundance to account for variation in sequencing coverage between samples.

(overlap in taxa shared between populations) will be analyzed using the Bray-Curtis 
dissimilarity metric48 in conjunction with multivariate statistical analysis methods that will 
include Principal Components Analysis (PCA) and Permutational Multivariate Analysis of 
Variance (PERMANOVA).49 Changes in abundance of individual taxa will also be analyzed 
using traditional univariate statistical methods. 
 
2.6  Correlative Studies 
We intend to perform correlative studies to understand the impact of anti-IL-23 antibody treatment 
post allogeneic hematopoietic progenitor cell transplantation. This testing should help us better 
understand the changes that are happening within the immune system to inhibit graft-versus-host 
disease (GVHD). We propose obtaining labs at a minimum of nine time points as follows: 
 
I) 
Baseline blood and plasma samples (at screening). 
II) 
Blood and plasma samples at the following time points:  days 7±3, 14±3, 21±3, 28±7, 
60±14, 90±14, 196±30, 365±30 post-transplant. 
III) 
Samples at the time of development of GVHD (if it occurs). 
3  STUDY DESIGN 
3.1  General Description 
This is a phase II, open-label, single-arm trial designed to evaluate the efficacy of tildrakizumab 
in improving GVHD relapse-free survival. 
 
Prior to embarking on the phase II portion of the study, we proposed a run-in of six patients to 
assess the safety and tolerability of tildrakizumab in patients undergoing MAC alloHCT. These 
six patients received the same dosing schema as the other patients in our proposed phase II 
study. The first three patients were followed through day 28 to ensure no evidence of primary 
graft failure. We saw no evidence of primary graft failure, thus, an additional three patients (similar 
to a 3+3 trial design) were treated on study and again, monitored through day 28 for evidence of 
primary graft failure. No evidence of graft failure was seen in these six patients. Thus, additional 
patients will be enrolled in the trial until the trial has reached full accrual or activated a stopping 
rule. 
 
 
3.2  Treatment Schema 
 
Patients enrolled on this clinical trial will receive tacrolimus initiating at day -3 at doses to maintain 
therapeutic levels per institutional preference and continued until at least day +90 post-transplant. 
Methotrexate will be administered intravenously and dosed at 15 mg/m2 days +1, and 10 mg/mg2 
on days +3, +6 and +11. Tildrakizumab will be administered subcutaneously at a dose of 100 mg 
on day -1, day 28±3, day 112±7, day 196±14, and day 280±14. 
 
Number of patients who will be enrolled in the study:  55. 
 
3.3  Rationale for Treatment Schema 
 
We propose early administration of tildrakizumab for acute GVHD prevention based on the fact 


 
 
 MCW Protocol No: PRO00035737 
27 
  Version No. 7 
 
 
Version Date: 10/31/2022 
that immediately following MAC, tissue injury ensues resulting in release of inflammatory 
mediators that provoke acute GVHD. We hypothesize that it is critical to have tildrakizumab 
present in order to block this inflammatory milieu, as outlined in Section 1.3. We propose 
continued administration of tildrakizumab to mediate a beneficial effect not only on the risk of 
aGVHD but also on cGVHD. The FDA-approved dosing of tildrakizumab for moderate to severe 
plaque psoriasis, based on a half-life of 21 to 24 days, is week 0, week 4 and every 12 weeks 
thereafter. We have maintained this dosing schedule [day -1 = week 0, day 28=week 4, day 112, 
day 196, day 280 are on the every-12-week schedule] and continued the tildrakizumab dosing 
through the period at highest risk for development of acute GVHD, conventionally thought to occur 
prior to day 100, and into the period of time during which chronic GVHD can occur, traditionally 
after day 100. 
 
3.4  Study Completion 
The study will reach study completion 24 months from the time the study opens to accrual. 
4  SUBJECT PARTICIPATION, DISCONTINUATION, AND  
    WITHDRAWAL 
MCW must follow all MCW IRB requirements and policies regarding subject participation, found 
here: 
 
https://www.mcw.edu/HRPP/Policies-Procedures.htm 
 
4.1  Subject Status 
 
Subject statuses throughout the trial are defined as follows:   
 
x 
Prescreening: preconsent (subject considering trial or study staff considering patient for 
the trial per institutional recruitment methods). 
x 
Screening: period after consent, but prior to eligibility confirmation. 
x 
Consented: consented, prior to eligibility confirmation. 
x 
Eligible: the local investigator confirms all eligibly criteria apply. 
x 
On study/enrolled: date eligibility is confirmed. 
x 
On arm: date of enrollment. 
x 
On treatment: first day treatment was given to the last day treatment was given. 
x 
Off treatment: the last day treatment was given. 
x 
On follow-up: from last day of treatment to the end of follow-up period. 
x 
Off study: follow-up period completed, with no additional data gathered. 
x 
Withdrawn: subject fully withdraws consent (i.e., refuses ALL follow-up, even survival) or 
is taken off study by the local PI. 
 
4.2  Prescreening and Screening Log 
 
The MCW study principal investigator regularly reviews screen failure reasons to understand 
barriers to accrual and consider amending eligibility criteria. Screen failures are defined as 
participants who were considered for the trial to participate in the clinical trial with or without 
consent but are not subsequently assigned to the study intervention or enrolled in the study. 


 
 
 MCW Protocol No: PRO00035737 
28 
  Version No. 7 
 
 
Version Date: 10/31/2022 
MCWCC CTO will follow its SOPs regarding prescreening and screening tracking. 
 
4.3  Consent  
 
Investigators or their appropriate designees will identify potentially eligible subjects from their 
clinics, subject self-referrals, referrals from other clinicians and/or other IRB-approved recruitment 
methods. No study conduct, including subject prescreening, can occur until after IRB approval. 
 
A written, signed informed consent form (ICF) must be obtained before any study-specific 
assessments are initiated. A signed ICF copy will be given to the subject and a copy will be filed 
in the medical record (per local IRB policies and SOPs). The original will be kept on file with the 
study records.  
 
4.4  Screening Procedures 
 
Refer to study calendar of events. 
 
Visit procedures that were performed as standard of care prior to consent (without the specific 
intent to make the subject eligible for the trial), may count towards screening tests and eligibility 
if they are within the screening window.

4.5  Eligibility Confirmation 
 
Study staff must adhere to MCWCC CTO SOPs regarding eligibility review/confirmation.  
 
Patients must have baseline evaluations performed prior to the first study drug dose and must 
meet all inclusion and exclusion criteria. In addition, the patient must be thoroughly informed about 
all study aspects, including the study visit schedule and required evaluations and all regulatory 
requirements for informed consent. The written informed consent must be obtained from the 
patient prior to enrollment. The following criteria apply to all patients enrolled onto the study, 
unless otherwise specified. 
 
In the unlikely event that a patient meets criteria during the pretransplant period but is no longer 
eligible at time of first administration of tildrakizumab, they will be removed and replaced on 
study.   
 
No waivers of protocol eligibility will be granted, but when clinical factors relating to an eligibility 
item are unclear or questionable, the study principal investigator (Lyndsey Runaas, MD 
lrunaas@mcw.edu) can only provide guidance or clarification on eligibility.

4.6  Discontinuation of Study Treatment, Withdrawal, and Compliance 
Discontinuation from the study treatment does not mean discontinuation from the study. Subject 
will be considered in follow-up, study procedures should still be completed as indicated by the 
study protocol and AEs/SAEs will continue to be reported according to this protocol. 
 
In the absence of treatment delays due to adverse events, study treatment/intervention may 
continue until:  
 
x 
Disease (relapse or progression of the primary malignancy) for which treatment is 
indicated. 
x 
Donor leukocyte infusion (DLI) prior to planned redose of tildrakizumab for any 
indication: infection, disease control or to address mixed chimerism. 
x 
Grade III–IV acute GVHD. Patients with grade I–II acute GVHD and on topical or 
V\VWHPLFFRUWLFRVWHURLGVWKHUDS\HTXLYDOHQWWRSUHGQLVRQHPJGFDQUHFHLYH
further doses of tildrakizumab. 
x 
Active chronic GVHD requiring systemic therapy. 
x 
General or specific changes in the subject’s condition renders the subject 
unacceptable for further treatment in the investigator’s judgment.  
x 
Inter-current illness that prevents further treatment administration.  
x 
Subject decides to withdraw from the study.  
x 
The subject has significant noncompliance with the protocol (see below).   
x 
Unacceptable adverse event(s) beyond requirements as detailed in this protocol.  
 
 
Subjects who sign the informed consent form, and are enrolled and receive the study intervention, 
but subsequently withdraw, or are withdrawn or discontinued from the study will not be replaced. 
 
Consent Withdrawal 
 
A subject may decide to withdraw from the study at any time. MCWCC CTO will follow its IRB of 
record’s SOPs regarding consent withdrawal.  
 
If a subject intends on withdrawing consent, staff should confirm which of the following options 
the subject chooses and document the discussion: 
 
x 
Full consent withdrawal, with no study follow-up. 
x 
Selective consent withdrawal from interventional portion of the study, but agrees to 
continued follow-up of associated clinical outcome information. 
Investigator-initiated Withdrawal 
The investigator will withdraw a subject whenever continued participation is no longer in the 
subject’s best interests. Reasons for withdrawing a subject include, but are not limited to, disease 
progression, the occurrence of an adverse event or a concurrent illness, a subject’s request to 
end participation, a subject’s noncompliance or simply significant uncertainty on the part of the 
investigator that continued participation is prudent. The reason for study withdrawal and the date 
the subject was removed from the study must be documented.

4.7  Lost to Follow-up 
The following actions must be taken if a participant fails to return to the clinic for a required 
study visit and/or is unable to be reached for follow-up: 
 
x 
The investigator or designee must make every effort to regain contact and/or reschedule a 
missed visit with the participant. 
x 
A participant is deemed lost to follow-up if his/her status cannot be obtained after all of the 
following occurs at two consecutive scheduled protocol calendar timepoints: 
o Three telephone calls (at least one day apart) from the study team are unanswered.  
AND  
o A letter to the participant’s last known mailing address goes unanswered.  
AND 
o These contact attempts must be documented in the participant’s medical record or 
study file.  
x 
Update OnCore® (follow-up tab and eCRF) when a participant is officially considered lost to 
follow-up. 
x 
If a subject is considered lost to follow-up, but subsequently contacts the study team, the 
subject should be considered in follow-up again. 
 
4.8  Accrual Suspension and Closure 
 
The MCW PI facilitates the suspension and closing of accrual in the following manner: 
 
x 
OnCore® tracks accrual throughout the study. 
x 
If the study must be suspended, OnCore® is updated to a ‘suspended’ status. 
x

Version Date: 10/31/2022 
All patients who are consented will be registered in OnCore®, the MCW Cancer Center Clinical 
Trial Management System. The system is password protected and meets HIPAA requirements. 
5.2  Registration Process 
Patients will be approached for this study after the decision to proceed with transplant is made 
and a suitable HLA-matched donor is identified. Transplant physicians will evaluate the patient 
eligibility into this study. All source documents that support eligibility include a signed informed 
consent/HIPAA and signed eligibility checklist. These must be available for review and 
verification.  
At the point of registration, the study staff will register the patient in the electronic database (where 
applicable), including demographic, consent and on-study information. The patient will be 
assigned a unique sequence number for the study. 
Patients will be enrolled on this trial within 30 days preceding the conditioning regimen for 
alloHCT. 
5.3  Pretreatment Period 
Pretransplant Evaluations 
The following observations must be completed within 30 days before the initiation of the 
conditioning regimen. 
x 
History, physical examination, height, and weight. 
x 
CBC with differential will be performed as appropriate during hospitalization for 
alloHCT on clinic visits and at minimum performed on days indicated on the 
schedule of events. 
x 
Comprehensive metabolic panel will be performed as appropriate during 
hospitalization for alloHCT, on clinic visits and at minimum performed on days 
indicated on the schedule of events. 
 
x 
HLA typing (donor and recipient). 
x 
Adverse events assessments. 
x 
Karnofsky Performance Status Scale and HCT-Specific Comorbidity Index score. 
x 
Infectious disease markers: CMV antibody, hepatitis panel (HepA Ab, HepB SAb, 
HepB SAg, HepB Core Ab, HepC Ab), HIV and HTLV I/II antibody. 
x 
EKG and LVEF (may be performed <30 days prior to patient enrollment).  
x 
Pulmonary function tests, including DLCO and FEV1 (may be performed <30 days 
prior to patient enrollment). 
x 
Disease evaluation of the malignant disease: For acute leukemia, CML and MDS, 
this includes a bone marrow aspirate and biopsy for pathology and cytogenetics.

x 
Pregnancy test per institutional practices for females of childbearing potential. 
NOTE: pregnancy test must be performed <30 days before initiation of the 
conditioning regimen. 
x 
Pretransplant blood samples for future research. 
Research (stool) sample will be collected pretransplant after admission to the 
hospital during the (pretransplant) conditioning period. Samples will be collected 
from each patient as a baseline and then at weekly intervals through the period 
of engraftment. In addition, stool samples will be obtained at the time of GVHD 
onset in any affected patients. Fresh fecal samples will be collected and 
immediately preserved in RNAlater solution, to facilitate optimal sample 
preservation, consistency of sample quality and ease of sample transport. 
Genomic DNA will be isolated from 200 mg of fecal sample using the Qiagen 
Powerlyzer Powersoil kit as described.40 Bacterial composition and abundance 
will be validated by quantitative PCR analysis. Composition of the microbiota will 
be determined through sequencing of the 16S rRNA gene V4 region (Diversigen, 
Baylor College of Medicine, Waco, TX). PCR products will be generated using a 
dual-indexing amplification strategy, then sequenced on the MiSeq platform 
(Illumina, San Diego, CA).  
 
5.4  Study Procedures during Treatment 
Patients must meet eligibility criteria eligible on day -1 to be treated.  
5.5  GVHD Assessment 
Patients will be monitored for development of acute and chronic GVHD, per standard operating 
procedures at the MCW BMT Program, but at minimum on days +28 (+/-7), +56 (+/-7), +100 (+/-
14), +180 (+14), +365 (+/-28) post-HCT. Diagnosis of acute GVHD may not necessitate biopsy 
confirmation in at least one involved organ but would be preferred. When more than one organ is 
involved, biopsy confirmation of all involved organs is recommended but not necessary. With liver-
only GVHD, biopsy confirmation is strongly recommended. Acute GVHD will be assessed by 
consensus criteria (Appendix 2),  and chronic GVHD diagnosis and grading will be according to 
NIH Criteria (please see Appendix 2).  
Independent GVHD adjudication is mandated in the study. Acute and chronic GVHD will be 
adjudicated by an independent Faculty Research Committee (FRC)-appointed review panel. 
Protocol PIs will be blinded to the adjudication panel and will not be permitted to grade or modify 
GVHD assessments. GVHD case report forms (CRFs) will be completed by treating 
MDs/NPs/APPs in real time, as indicated in study calendar. FRC adjudication panel will grade 
GVHD, using a calendar-driven approach (days +100 and +180 for aGVHD and days +180 and 
+365 for chronic GvHD).

6.2  Standard GVHD Prophylaxis Administration 
6.2.1  Tacrolimus 
Tacrolimus will be given per standard operating procedures from the MCW BMT program, 
intravenously at a dose of 0.03 mg/kg/day starting day –3. Subsequent dosing will be based on 
blood levels. The dose should be adjusted accordingly to maintain a suggested level of 5–10 
ng/mL. The dose of tacrolimus may be switched to oral at a 1:3 dose equivalence and rounded to 
the nearest 0.5 mg at the discretion of the treating physician. If patients are on medications which 
alter the metabolism of tacrolimus (e.g., azoles), the initial starting dose and subsequent doses 
should be altered, as per institutional practices. Tacrolimus taper can be initiated at a minimum 
of 90 days post-HSCT, if there is no evidence of active GVHD. The rate of tapering will be done 
according institutional practices, but patients should be off tacrolimus by day 180 post-HSCT.

7  ADVERSE EVENTS: DEFINITIONS AND REPORTING  
    REQUIREMENTS 
 
7.1  DEFINITIONS 
 
7.1.1  Adverse Event  
 
Any untoward medical occurrence in a patient or clinical investigation subject administered a 
pharmaceutical product and which does not necessarily have to have a causal relationship with 
this treatment. (International Conference on Harmonisation [ICH], E2A, E6). This study will utilize 
the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 5.0, located on the 
CTEP web site: 
https://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm  
AEs may be spontaneously reported by the patient and/or in response to an open question from 
study personnel or revealed by observation, physical examination or other diagnostic 
procedures. 


 
 
 MCW Protocol No: PRO00035737 
38 
  Version No. 7 
 
 
Version Date: 10/31/2022 
 
7.1.2  Serious Adverse Event (SAE)  
 
Serious Adverse Event (SAE) means any untoward medical occurrence that results in any of the 
following outcomes: 
x 
Death. Results in death. 
x 
Life-threatening. Is life-threatening (refers to an AE in which the patient was at risk of 
death at the time of the event. It does not refer to an event which hypothetically might have 
caused death if it were more severe). 
x 
Hospitalization. Requires inpatient hospitalization or prolongation of an existing 
hospitalization. 
x 
Disability/incapacity. Results in persistent or significant disability or incapacity. 
(Disability is defined as a substantial disruption of a person’s ability to conduct normal life 
functions). 
x 
Pregnancy. 
x 
Medically important event. This refers to an AE that may not result in death, be 
immediately life threatening, or require hospitalization, but may be considered serious 
when, based on appropriate medical judgment, may jeopardize the patient, require 
medical or surgical intervention to prevent one of the outcomes listed above, or involves 
suspected transmission via a medicinal product of an infectious agent. Examples of such 
medical events include allergic bronchospasm requiring intensive treatment in an 
emergency room or at home, blood dyscrasias or convulsions that do not result in inpatient 
hospitalization, or the development of drug dependency or drug abuse; any organism, 
virus, or infectious particle (e.g., prion protein transmitting transmissible spongiform 
encephalopathy), pathogenic or nonpathogenic, is considered an infectious agent. 
7.1.3 Attribution of an Adverse Event 
An assessment of the relationship between the adverse event and the medical intervention, using 
the following categories:  
Definitely Related: The AE is clearly related to the intervention. There is clear evidence to 
suggest a causal relationship, and other possible contributing factors can be ruled out.  
Probably Related: The AE is likely related to the intervention. There is evidence to suggest a 
causal relationship, and the influence of other factors is unlikely.  
Possibly Related: The AE may be related to the intervention. There is some evidence to suggest 
a causal relationship (e.g., the event occurred within a reasonable time after administration of the 
trial medication). However, the influence of other factors may have contributed to the event (e.g., 
the subject’s clinical condition, other concomitant events).  
Unlikely: The AE is doubtfully related to the intervention. A clinical event, including an abnormal 
laboratory test result, whose temporal relationship to drug administration makes a causal 
relationship improbable (e.g., the event did not occur within a reasonable time after administration 


 
 
 MCW Protocol No: PRO00035737 
39 
  Version No. 7 
 
 
Version Date: 10/31/2022 
of the trial medication) and in which other drugs or chemicals or underlying disease provides 
plausible explanations (e.g., the subject’s clinical condition, other concomitant treatments).  
Unrelated: The AE is clearly NOT related to the intervention. The AE is completely independent 
of study drug administration, and/or evidence exists that the event is definitely related to another 
etiology.  
7.1.4  Expectedness of an Adverse Event 
 
Study investigator or treating physician will be responsible for determining whether an AE is 
expected or unexpected, as indicated in the protocol, informed consent form and/or drug 
information brochure. An AE will be considered unexpected if the nature, severity, or frequency 
of the event is NOT consistent with the risk information previously described for the study 
intervention. 
7.2  Collection and Reporting Requirements for Adverse Events and Serious Adverse 
Events 
 
Only grade 3,4 and 5 adverse events (including SAEs) must be recorded in OnCore® and/or an 
adverse event log. All AEs required to be collected must be graded according to the CTCAE v5. 
When possible, signs and symptoms indicating a common underlying pathology should be noted 
as one comprehensive event. Investigator’s or treating physician’s assessment of AE attributions 
must also be documented.  
AEs will be collected from the time the subject signs the consent form through 30 days post last 
dose of study drug(s). AEs will be tracked and followed until resolution, subject withdraws 
consent, or is lost to follow-up (including subjects who discontinue early). All adverse events 
collected per the protocol will be followed with appropriate medical management until they are 
resolved, if they are related to the study treatment, or until the investigator deems the event to be 
chronic. Please see section 7.2.2 and Table 1 to identify the adverse events that need to be 
reported.  
7.2.1  Reporting of Adverse Events and Serious Adverse Events 
Please refer to Table 1 below to identify adverse events that meet reporting requirements.  
All serious adverse events (SAEs) that occur after the subject has signed the consent form 
through 30 days post last dose of study drug(s) will be reported. All SAEs will be followed until 
satisfactory resolution, or until the investigator deems the event to be chronic. All serious adverse 
events (SAEs) must also be documented in OnCore®.

9  CORRELATIVE STUDIES/SPECIAL STUDIES 
9.1  DESCRIPTION 
We intend to perform correlative studies to understand the impact of anti-IL-23 antibody treatment 
post allogeneic hematopoietic progenitor cell transplantation. This testing should help us better 
understand the changes that are happening within the immune system to inhibit graft-versus-host 
disease (GVHD). 
 
We plan to perform the analysis of immune cells subsets from fresh or frozen peripheral blood 
mononuclear cells by flow cytometry, with the hypothesis that treatment with anti-IL-23 antibody 
will prevent alterations in circulating immune cell subsets and cytokines/biomarkers that are 
associated with development of GVHD.  


 
 
 MCW Protocol No: PRO00035737

  Version No. 7 
 
 
Version Date: 10/31/2022 
Analysis of immune cell subsets from fresh or frozen peripheral blood mononuclear cells (PBMCs) 
by flow cytometry 
 
As a measure of systemic immunity (using PBMCs), the relative percentage of circulating immune 
cells will be assessed by multiparametric flow cytometry. Multiparametric flow cytometry will allow 
for identification of immune cell subsets by recording the simultaneous expression of biomarkers 
unique to that cell subset. Flow cytometry will be performed on a MACS Quant flow cytometer in 
the Cell Therapy Laboratory at the Medical College of Wisconsin. We will use flow cytometry of 
antibody stained PBMCs to evaluate the relative percentage of cell types including T, B, NK and 
myeloid cells. Correlating changes in immune cell subsets upon anti-IL-23 therapy will facilitate 
the identification of a peripheral immune signature that correlates with absence or presence of 
GVHD. We will test for the expression of the following immune cell markers: T cell marker panel 
(includes regulatory T cell markers): CD3, CD4, CD8, CD25, CD44, CD62L, CD56, CD127, Foxp3 
(intracellular), phospho-STAT3 (intracellular); NK cell marker panel: CD56, CD16, CD3; Myeloid 
cell marker panel: CD11b, CD33, CD14; B cell marker panel: CD19, CD20. 
 
We also intend to perform the analysis of cytokines and biomarkers in blood plasma. Plasma, or 
serum, cytokine and biomarker signatures can provide important information regarding peripheral 
immune responses. Changes in serum cytokines and other biomarkers have been reported during 
GVHD and in cancer patients. However, currently, there are no defined cytokine signatures that 
are predictive of outcome following allogeneic hematopoietic progenitor cell transplantation.  
Analysis of cytokines and biomarkers in blood plasma (Luminex® platform) 
 
For this study, plasma cytokines and other biomarkers will be analyzed longitudinally before and 
after immune therapy with anti-IL-23 antibody. Serum cytokines will be quantified using 
customized Luminex® bioplex assays. For the cytokine array, we will analyze the following: IL-1, 
IL-2, IL-4, IL-6, IL-10, IL-17, IL-23, TNFD, GM-CSF, IFNJ. The biomarker array will analyze the 
following: ST2, REG3A, BAFF, CCL15, MMP3, CXCL9, CXCL10, osteopontin, soluble CD163. 
 
9.2  Instructions Regarding Sample Collection for Correlatives: 
For each time point, one 10 ml red top tube and one 10 ml purple top tube will be collected. 
Once the samples are collected, study coordinator will contact the BMT and Cell Therapy 
Laboratory (414-805-6143). 
The samples will be transferred to Dr. Bryon Johnson’s lab once collected (no spinning or other 
special handling). They can be at room temperature. If they were to be collected on weekends 
or holidays, the samples should be stored at 4°C until they are transferred to the lab.

The biomarker analysis set will include all patients in the efficacy analysis set who have at 
least one evaluable biomarker sample. 
10.3.1  Primary Analysis (or Analysis of Primary Endpoints) 
The primary endpoint will be evaluated in the efficacy analysis set. The GRFS will be estimated 
using the Kaplan-Meier estimator and plotted with a 90 FRQILGHQFH EDQG. An event for this 
outcome is defined as grade III–IV acute GVHD, chronic GVHD requiring systemic therapy, 
relapse or death. Patients who are alive without GVHD or relapse will be censored at the last

that will include Principal Components Analysis (PCA) and Permutational Multivariate Analysis of 
Variance (PERMANOVA).49 Changes in abundance of individual taxa will also be analyzed using 
traditional univariate statistical methods. 
 
10.3.3  Other Analyses/Assessments 
Demographic and other baseline data, such as disease characteristics, as well as outcome 
measures, will be presented for the full analysis set overall and separately for unrelated and 
matched related donor patients. Categorical data, such as gender, race, etc. will be presented by 
frequencies and percentages. Descriptive summary statistics (e.g., frequency, mean, median, 
range and standard deviation) will be used to present numeric data.  
10.4  Evaluation of Safety 
 
Analyses will be performed for all patients having received at least one dose of study drug. The 
study will use the NCI CTCAE v5. The frequency and proportion of patients experiencing an

H[FHHGV. A Beta prior distribution with effective sample size of 1 and mean equal to the 
historical value was used with a maximum of 37 patients, and a continuous evaluation starting 
at two patients. The following tables show the number of 100-day mortality and grade 3–4 
aGVHD events that would trigger a safety review depending on the number of evaluable 
patients. For the purposes of the safety monitoring patients in the safety set who are alive with 
at least 100 days of follow-up or have experienced the monitored event within 100 days are 
considered evaluable.

If a stopping rule is triggered based on excessive 100-day mortality or 100-day grade III–IV 
aGVHD, the trial will be paused. The DSMC will meet and review all relevant data. They will 
determine the relevant next steps in terms of permanent discontinuation of the trial versus 
additional safety modifications needed to allow the trial to continue.  
11  DATA AND SAFETY MONITORING PLAN (DSMP) 
Data and Safety Management Overview 
The Medical College of Wisconsin (MCW) Data and Safety Monitoring Committee (DSMC) and 
the MCW Institutional Review Board (IRB) will approve protocol-specific DSM plans. A local, 
investigator-initiated trial will be required to be continuously monitored by the principal investigator 
of the study with safety and progress reports submitted to the DSMC.  
The DSMP for this study will involve the following entities: 
11.1  Study Team 
The study team minimally consists of the principal investigator, the clinical research coordinator, 
regulatory specialist and the study biostatistician. While subjects are on study, the principal 
investigator will meet regularly with the research coordinator and the study biostatistician to review 
study status. This review will include but not be limited to reportable SAEs and UPIRSOs and an 
update of the ongoing study summary that describes study progress in terms of the study schema. 
The appropriateness of further subject enrollment and the specific intervention for a next subject 
enrollment is addressed. All meetings, including attendance, are documented.

11.2  Quality Assurance 
This protocol was classified as high risk and will be reviewed internally by the MCW Cancer 
Center Clinical Trials Office Quality Assurance Staff according to the MCWCC Data and Safety 
Monitoring Plan and current version SOP, 6.5.2 Internal Quality Assurance Reviews. 
 
11.3  Clinical Trials Office 
The MCWCC Clinical Trials Office [CTO] provides administrative assistance and support to the 
DSMC.  
11.4  DSMC 
The Medical College of Wisconsin Cancer Center places the highest priority on ensuring the 
safety of patients participating in clinical trials. Every cancer interventional trial conducted at 
MCW includes a plan for safety and data monitoring. 
More information can be found related to the MCWCC Data and Safety Monitoring Plan at the 
MCWCC website (Data and Safety Monitoring Plan).  
This study will be reviewed by the Medical College of Wisconsin Cancer Center Data and Safety 
Monitoring Committee (MCWCC DSMC). A summary of the MCWCC DSMC activities are as 
follows:  
 
Review the clinical trial for data integrity and safety.  
 
Review all DSM reports.  
 
Submit a summary of any recommendations related to study conduct.  
 
Terminate the study if deemed unsafe for patients.  
A copy of the MCWCC Data and Safety Monitoring Plan and membership roster will be maintained 
in the study research file and updated as membership changes. The committee will review reports 
from the study PI twice annually (or more frequently if needed) and provide recommendations on 
trial continuation, suspension or termination, as necessary.  
Any available DSMC letters will be submitted to the IRB of record as required. 
12 REGULATORY COMPLIANCE, ETHICS AND STUDY MANAGEMENT 
12.1  Ethical Standard 
This study will be conducted in accordance with the ethical principles that have their origin in the 
Declaration of Helsinki, as stated in 21 CFR §312.120(c)(4); consistent with GCP and all 
applicable regulatory requirements. 
12.2  Regulatory Compliance 
This study will be conducted in compliance with: 
 
The protocol. 


 
 
 MCW Protocol No: PRO00035737 
50 
  Version No. 7 
 
 
Version Date: 10/31/2022 
 
Federal regulations, as applicable, including: 21 CFR 50 (Protection of Human 
Subjects/Informed Consent); 21 CFR 56 (Institutional Review Boards) and §312 
(Investigational New Drug Application; and 45 CFR 46 Subparts A (Common Rule), B 
(Pregnant Women, Human Fetuses and Neonates), C (Prisoners), and D (Children), 
GCP/ICH guidelines, and all applicable regulatory requirements. The IRB must comply 
with the regulations in 21 CFR §56 and applicable regulatory requirements. 
12.3  Prestudy Documentation 
Prior to implementing this protocol at MCWCC, the protocol, informed consent form and any other 
information pertaining to participants must be approved by the MCW IRB.  
12.4  Institutional Review Board 
The protocol, the proposed informed consent form and all forms of participant information related 
to the study (e.g., advertisements used to recruit participants) will be reviewed and approved by 
the MCW Institutional Review Board. Prior to obtaining MCW approval, the protocol must be 
approved by the Medical College of Wisconsin Cancer Center Scientific Review Committee. The 
initial protocol and all protocol amendments must be approved by the IRB prior to implementation.  
Informed Consent Process 
Informed consent is a process that is initiated prior to the individual’s agreeing to participate in 
the study and continues throughout the individual’s study participation. Extensive discussion of 
risks and possible benefits of this therapy will be provided to the subjects and their families. 
Consent forms describing in detail the study interventions/products, study procedures and risks 
are given to the subject and written documentation of informed consent is required prior to starting 
intervention/administering study product. 
Potential subjects will be told, and a statement will be included that this study is designed to 
determine both safety and effectiveness. The consent forms will include the approved MCW IRB 
template language. 
Consent forms will be IRB-approved and the subject (and legally authorized representative, if 
necessary) will be asked to read and review the document. The treating physician or the 
investigator will explain the research study to the subject and answer any questions that may 
arise. The study coordinator may complete the consenting process. In accordance with 46 CR 
46.111, the subject will sign and date the informed consent document prior to any procedures 
being done specifically for the study.  
A witness should only sign when required, per FH/MCW IRB policy. If a witness signs the 
document when not required, the study staff should document in the legal medical record (or note 
to file) the relationship to the patient and why a witness signed. (For example, “Although not 
required, the subject’s spouse was present during the consenting process and signed as the 
witness.” Or “Although not required, hospital staff was present for consenting process and signed 
as a witness.”) 
The subjects will have the opportunity to discuss the study with their surrogates or think about it 
prior to agreeing to participate. The subjects may withdraw consent at any time throughout the 
course of the trial.  


 
 
 MCW Protocol No: PRO00035737 
51 
  Version No. 7 
 
 
Version Date: 10/31/2022 
A copy of the informed consent document will be given to the subjects for their records. The rights 
and welfare of the subjects will be protected by emphasizing to them that the quality of their 
medical care will not be adversely affected if they decline to participate in this study. If there are 
changes to the consent form, all revisions will be reviewed with study subject at the next 
appropriate opportunity. Patients that require reconsenting will be defined in the IRB approved 
amendment submission. The process for obtaining informed consent will again be performed. 
Study subjects will not be reconsented for continuing reviews. The MCWCC CTO will follow the 
MCW/FH IRB’s policy for subjects who demonstrate limited English proficiency or limited literacy.  
After the subject’s visit in which the consent is signed, it is documented in the clinic chart that the 
consent has been signed and that all questions have been answered to the subject’s satisfaction 
after adequate time for review of the consent. It is also documented that a copy of the consent is 
given to the subject. The original consent is kept with the subject’s study file, and a copy of the 
consent is sent to the OCRICC office, which will then submit to HIM a copy of the signed consent 
to be scanned into EPIC, the legal medical record. 
12.5 Subject Confidentiality and Access to Source Documents/Data 
Subject confidentiality is strictly held in trust by the sponsor-investigator, participating 
investigators, and any staff, and the sponsor. This confidentiality includes the clinical information 
relating to participating subjects, as well as any genetic or biological testing. 
The study protocol, documentation, data, and all other information generated will be held in strict 
confidence. No information concerning the study, or the data will be released to any unauthorized 
third party without prior written approval of the principal investigator. 
The conditions for maintaining confidentiality of the subjects’ records are required for the life of 
the data. These rules apply equally to any and all MCWCC projects.  
One risk of taking part in a research study is that more people will handle the personal health 
information collected for this study. The study team will make every effort to protect the information 
and keep it confidential, but it is possible that an unauthorized person might see it. Depending on 
the kind of information being collected, it might be used in a way that could embarrass the subject 
or affect his/her ability to get insurance. 
While data are being collected and after all data have been collected but are still in the process 
of being analyzed, the subject’s data/PHI are stored in the locked Clinical Research Office in the 
Clinical Trials Office. Databases in which the study subject information is stored and accessed 
are password protected, allowing for limited access by authorized personnel only. Data/PHI kept 
in the Case Report Forms contain the study identifiers, subject initials, date of birth and date of 
service.  
Personal identifiers, such as name and medical record number, will be removed from 
accompanying lab reports and test results. Any data/PHI that are not stored for the purposes of 
the study are shredded in the Clinical Trials Office. 
After all study queries and analyses are completed, the data/PHI will not be destroyed but will be 
archived in a secure long-term storage site in order to keep an accurate record of screened and 
enrolled subjects for the sponsor and potential audit purposes only specific for this study.  
12.6  Protection of Human Subjects 


 
 
 MCW Protocol No: PRO00035737 
52 
  Version No. 7 
 
 
Version Date: 10/31/2022 
12.6.1  Protection from Unnecessary Harm 
Each clinical site is responsible for protecting all subjects involved in human experimentation. This 
is accomplished through the IRB mechanism and the informed consent process. The IRB reviews 
all proposed studies involving human experimentation and ensures that the subject’s rights and 
welfare are protected and that the potential benefits and/or the importance of the knowledge to 
be gained outweigh the risks to the individual. The IRB also reviews the informed consent 
document associated with each study in order to ensure that the consent document accurately 
and clearly communicates the nature of the research to be done and its associated risks and 
benefits. 
12.6.2  Protection of Privacy 
As noted, patients will be informed of the extent to which their confidential health information 
generated from this study may be used for research purposes. Following this discussion, they 
will be asked to sign informed consent documents. The original signed document will become 
part of the patient’s medical records, and each patient will receive a copy of the signed 
document.  
12.6.3  Changes in the Protocol 
 
Once the protocol has been approved by the MCW IRB, any changes to the protocol must be 
documented in the form of an amendment. The amendment must be signed by the investigator 
and approved by IRB prior to implementation.  
If it becomes necessary to alter the protocol to eliminate an immediate hazard to patients, an 
amendment may be implemented prior to IRB approval. In this circumstance, however, the 
investigator must then notify the IRB in writing within five working days after implementation.  
The IRB may provide, if applicable regulatory authority(ies) permit, expedited review and 
approval/favorable opinion for minor change(s) in ongoing studies that have the approval 
/favorable opinion of the IRB. The investigator will submit all protocol modifications to the sponsor 
and the regulatory authority(ies) in accordance with the governing regulations. 
Changes to the protocol may require approval from the sponsor. 
Any departures from the protocol must be fully documented in the source documents. 
12.7  Investigator Compliance  
The investigator will conduct the study in compliance with the protocol given approval/favorable 
opinion by the IRB and the appropriate regulatory authority(ies).  
13  DATA HANDLING AND RECORD KEEPING 
13.1  Overview 
Every effort is made to uphold the integrity of the project, the research, the institution, and the 
researchers involved. Data collection guidelines and methodologies are carefully developed 
before the research begins. Investigators focus on the following to ensure data integrity:  well-
trained data collectors/recorders to ensure consistency and quality, well-designed data collection 


 
 
 MCW Protocol No: PRO00035737

Version Date: 10/31/2022 
protocols and ongoing monitoring. In this way, study rigor and validity are maintained. Data is 
protected from physical damage as well as from tampering, loss or theft. This project’s data 
management is a multidisciplinary activity that includes investigators, research coordinators and 
nurses, data mangers, support personnel, biostatisticians and database programmers. Quality 
control will be applied to each stage of data handling to ensure that all data are reliable and have 
been processed correctly.  
13.2  Data Management Responsibilities 
13.2.1  Principal Investigator 
The principal investigator oversees the management of patient records/case report forms and 
ensures that a) complete and accurate data will be obtained and provided to the sponsor; b) 
patient records are maintained to include history, prescribed medication and investigational 
product(s), measurements, exams, evaluations and adverse events; c) corrections are applied to 
clinical research data according to principles of good research practice (i.e., single-line delete, 
date and initial). He or she will ensure that there is correlation between the case report forms and 
the source documents.  
13.2.2  Research Coordinator 
 
A research coordinator creates, collects and organizes clinical trial documentation. He or she 
ensures that source documentation and data abstraction and entry are being done at protocol 
specified time points. 
 
13.2.3  Research Nurse/Medical Staff 
 
The research nurse and medical staff documents protocol-required care or assessment of the 
subject’s outcomes, adverse events and compliance to study procedures. 
13.2.4  Biostatistician 
 
The biostatistician may assist in CRF development (content and design), dataset specifications 
(annotation of CRFs and record layout) and validation. 
13.3  Handling and Documentation of Clinical Supplies 
The MCWCC Principal Investigator will maintain complete records showing the receipt, 
dispensation, return, or other disposition of all investigational drugs. The date, quantity and batch 
or code number of the drug, and the identification of patients to whom study drug has been 
dispensed by patient number and initials will be included. The sponsor-investigator will maintain 
written records of any disposition of the study drug. 
The principal investigator shall not make the investigational drug available to any individuals other 
than to qualified study patients. Furthermore, the principal investigator will not allow the 
investigational drug to be used in any manner other than that specified in this protocol. 
 
13.4  Source Documents 
Source documents for clinical information (patient history, diagnosis, clinical and diagnostic test 
reports, etc.) are maintained in the patient’s clinical file.

The principal investigator is required to prepare and maintain adequate and accurate case 
histories that record all observations and other data pertinent to the investigation on each 
individual administered the investigational drug or employed as a control in the investigation. Case 
histories include the case report forms and supporting data including, for example, signed and 
dated consent forms and medical records including, for example, progress notes of the physician, 
the individual's hospital chart(s), and the nurses' notes. The case history for each individual shall 
document that informed consent was obtained prior to participation in the study. 
Study documentation includes all CRFs, data correction forms or queries, source documents, 
sponsor-investigator correspondence, monitoring logs/letters, and regulatory documents (e.g., 
protocol and amendments, IRB correspondence and approval, signed patient consent forms). 
Source documents include all recordings of observations or notations of clinical activities and all 
reports and records necessary for the evaluation and reconstruction of the clinical research study. 
In accordance with FDA regulations, the investigator shall retain records for a period of two years 
following the date a marketing application is approved for the drug for the indication for which it is 
being investigated; or, if no application is to be filed or if the application is not approved for such 
indication, until two years after the investigation is discontinued and FDA is notified.

CONSENT TO PARTICIPATE IN RESEARCH 
A1. INTRODUCTION – WHY ARE WE ASKING YOU TO PARTICIPATE? 
You are being invited to participate in this research because you have a type of cancer that will 
be treated with an allogenic HCT.  Developing acute GVHD is a risk of this type of transplant.  
Because of your condition, you may be eligible for a research project using an investigational 
drug, Tildrakizumab, and standard GVHD prophylaxis to treat your disease.  
 
A total of about 55 people are expected to participate in this research at the Medical College of 
Wisconsin/Froedtert Hospital. 
 
The Director of the project is Lyndsey Runaas, MD in the Division of Hematology & Oncology. A 
research team works with Dr. Runaas. You can ask who these people are.  
 
Sun Pharmaceuticals is providing support for this study. 
 
A2. DO I HAVE TO PARTICIPATE? 
You can decide whether to take part in this research or not. You are free to say yes or no. If you 
say no, your regular medical care will not change. Even if you join this project, you do not have 
to stay in it. You may stop at any time.  
 
A research project is different from routine medical care in three ways: 1) there are extra risks 
that we will tell you about in this form; 2) you may have some extra medical tests and visits; 3) 
the research procedures, tests and visits follow a set plan that must be kept. 
 
A3. WHY IS THIS PROJECT BEING DONE? 
In this study we want to find out if giving Tildrakizumab (100 mg) as a subcutaneous injection on 
Day -1 in combination with the standard GVHD prophylaxis; Tacrolimus and Methotrexate will 
help prevent acute and chronic GVHD. Tildrakizumab (100 mg) subcutaneous injection will also 
be given on Day +28, Day +112, Day +196 and Day +280 after your bone marrow transplant. 
We also want to find out whether the investigational drug combination is safe to use and 
whether it reduces the symptoms of acute and chronic GVHD. 
 
Everyone in this study will receive the combination of Tildrakizumab and standard GVHD 
prophylaxis. This research and your samples will help us in creating controls and active drug 
levels for future research studies. The combination of Tildrakizumab and standard GVHD 
prophylaxis is still experimental and is not approved by the U.S. Food and Drug Administration.

B1. WHAT WILL HAPPEN IF I PARTICIPATE? 
Treatment Schedule 
 
Before the research starts (screening):   
After signing this consent form, you will be asked to undergo some screening tests or 
procedures to find out if you can be in the research study.  Many of these tests and procedures 
are likely to be part of regular cancer care and may be done even if it turns out that you do not 
take part in the research study.  If you have had some of these tests or procedures recently, 
they may or may not have to be repeated.   
 
Screening procedures:  
If the screening information shows that you meet the requirements, then you will complete the 
following:   
x 
Medical History, which includes questions about your health, current medications. 
x 
Physical Exam, which includes your height, weight 
x 
Your performance status, which evaluates how you are able to carry on with your usual 
activities.  
x 
Routine Blood tests (about 4 tablespoons)  
x 
Pregnancy test if you are able to have children 
x 
Infections disease markers 
x 
HLA typing  
x 
PFT: to test the function of your lungs 
x 
Bone marrow biopsy and/or aspirate, to evaluate the extent of your disease. For this 
test, a sample of bone marrow cells is taken by a needle inserted into a bone in your 
body. If a bone marrow biopsy is needed, a small piece of bone and the attached bone 
marrow is removed. These tests may be done under local anesthesia.  
x 
Research blood samples (approximately 4 teaspoons) to help understand the changes 
that are happening with your immune system to prevent GVHD  
 
If the screening information shows that you cannot be in the research, the research doctor will 
discuss other options with you and/or refer you back to your regular doctor.

You will be in this research project for about 12 months following your bone marrow transplant. 
 
B3. CAN I STOP BEING IN THE PROJECT?   
You are free to withdraw from the project at any time. If you leave, your regular medical care will 
not change. If you are thinking about leaving, please tell the research doctor.  
 The research doctor can tell you about the effects of stopping, and you and the research 
doctor can talk about what follow-up care would help you the most. 
 You might be asked to come back for one more visit to check your health. 
 
The research doctor may take you out of this project at any time. This would happen if: 
x 
They think it is in your best interest. 
x 
You do not follow the project rules. 
x 
The whole project is stopped. 
If this happens, the research doctor will tell you. 
 
B4. ARE THERE ANY SPECIAL INSTRUCTIONS WHILE I AM IN THE PROJECT?  
x 
While you are participating in this study (during treatment), you can participate in other 
research studies as long as they are NOT GVHD prevention or treatment.  
 
x 
You should also report to your doctor any changes in your health or side effects that you 
may be experiencing.  
 
x 
You will be asked to receive all study-required treatments and complete all study-required 
procedures.  
 
C1. WHAT HEALTH RISKS OR PROBLEMS CAN I EXPECT FROM THE PROJECT? 
There are risks to taking part in any research project. There is a risk that you may get a drug 
combination that does not help your condition or may make it worse.  There also may be 
problems (side effects) we do not know about yet, from the combination of Tildrakizumab and 
standard GVHD prophylaxis themselves, or how they combine with other drugs you are taking. 
If we learn about new important side effects, we will tell you.  
 
We watch everyone in the project for problems (side effects). You need to tell the research 
doctor or a member of the research team immediately if you experience any problems, 
side effects, or changes in your health. If you have signs of fever or other new abnormal 
symptoms, call Dr. Runaas immediately at 414-805-6700. In an emergency, call 911.

Blood Draws (for research blood and plasma, and pharmacokinetic labs) 
Having your blood drawn can be uncomfortable and can sometimes cause a bruise. In rare 
cases, a blood draw can cause fainting. If you have fainted before when your blood was drawn 
please let the person drawing your blood know. Only trained people will draw your blood. 
 
Bone marrow biopsy and bone marrow aspirate 
Bone marrow aspirate and/or biopsy are each performed using a hollow needle to remove a small 
sample of bone marrow.  Before the biopsy, a local anesthetic is used to numb the area where the 
needle(s) will be inserted.  The sterile procedure may cause discomfort, pain, bleeding, scarring 
or infection at the site of the aspirate and/or biopsy. 
 
 
 
C4. REPRODUCTIVE RISKS 
Risks to women who could become pregnant 
The drugs in this project might affect a baby, before or after the baby is born. We do not know if 
the drugs cause(s) harm to a baby, so we do not want anyone who might be pregnant to enter 
the project. You should not become pregnant or nurse a baby while in this project. You must tell 
the research doctor right away if you think you are pregnant. You will be asked to have a 
pregnancy test to be sure you are not pregnant at the start of the project.  
 
If you become pregnant during the project, you will be dropped from participation for safety 
reasons. If you become pregnant while you are taking this experimental drug we ask that you 
inform the research doctor immediately. The research doctor will ask you for written permission 
to obtain information from you or your obstetrician on your pregnancy and the health of the 
baby. 
 
Risks of fathering a child 
You should not father a baby while taking part in this project because it is unknown if the drugs 
could affect a baby. If your partner is able to become pregnant, one or both of you must use 
some form of effective birth control.  You must tell the research doctor right away if you think 
your partner is pregnant. 
 
If you think that you have fathered a baby while you are taking this experimental drug, we ask 
that you inform the research doctor immediately. At that time, the research doctor will ask 
permission of your partner for the use and disclosure of her health information regarding the 
pregnancy. She will be asked to sign a separate consent form. She can choose to do this or not. 
She will be asked to sign this form to allow your research doctor to contact her obstetrician to 
collect information on the progress of the pregnancy and its outcome. The research doctor will 
make this information available to the sponsor for safety monitoring. 
 
Birth control methods for all subjects 
Check with the research doctor about the birth control methods needed for this project and how 
long to use them. Some methods might not be good enough for this project. If you are having 
sex that could lead to pregnancy, you should use birth control while you are in this project.

We will not use your personal health information for a different project without your permission 
or the permission of a hospital research review board (IRB). Once all personal identification is 
removed from your health information, the information may be used for future research or 
distributed to another investigator for future research without additional informed consent from 
you or your legally authorized representative. The information might also be used or released 
for other purposes without asking you. Results of the project may be presented in public talks or 
written articles, but no information will be presented that identifies you. 
  
E3. What are the risks of sharing this health information? 
One risk of taking part in a research project is that more people will handle your personal health 
information collected for this project. The research team will make every effort to protect the 
information and keep it confidential, but it is possible that an unauthorized person might see it. 
Depending on the kind of information being collected, it might be used in a way that could 
embarrass you or affect your ability to get insurance. If you have questions, you can talk to the 
research doctor about whether this could apply to you.  
 
E4. How long will you keep the health information for this project? 
If you sign this form, we plan to keep your information without any end-date in case we need to 
check it again for this project. 
 
E5. Can I cancel my permission to share this health information? 
If you change your mind later and do not want us to collect or share your health information, you 
need to send a letter to: 
Lyndsey Runaas, MD  
Froedtert & the Medical College of Wisconsin 
Division of Hematology and Oncology 
9200 W. Wisconsin Avenue 
Milwaukee WI 53226 
 
The letter must say that you have changed your mind and do not want the researcher to collect 
and share your health information. At that time, we may decide that you cannot continue to be 
part of the project. We may still use the information we have already collected.
