An open label, multicenter, phase II trial testing single agent decitabine in TP53 mutated 
relapsed/refractory acute myeloid leukemia 
 
SCHEMA 
 
 
A bone marrow biopsy may be performed at any time after Cycle 2 if there is clinical concern for progression. 
 
Patients with progressive disease after 2 cycles of decitabine (10 days each) may be removed from study. 
 
After Cycle 2, decitabine dose will be reduced FOR ALL PATIENTS from 20 mg/m2/day x 10 days to 20 mg/m2/day 
x 5 days. After Cycle 1, patients with blast counts <5% may reduce decitabine dose from 20 mg/m2/day x 10 days to 
20 mg/m2/day x 5 days. Each cycle is 28 days. 
 
Notes for transplant eligible patients 
Anytime after 3 cycles, transplant eligible patients in CR, CRc, CRi, or mLFS* should proceed to stem cell 
transplant according to institutional protocols. 
After 3 cycles, transplant eligible patients in PR* may be removed from study and proceed to salvage according to 
institutional protocols. 
 
Notes for transplant ineligible patients  
Transplant ineligible patients will continue on study with decitabine (x 5 days) until relapse or progression, with 
the exception of patients with SD* after 4 cycles who may continue on therapy or be removed from study per treating 
physician preference. 
 
Antimicrobial prophylaxis during therapy is strongly recommended due to anticipated neutropenia. Common agents 
include acyclovir, ciprofloxacin, and fluconazole. Alternative agents may be used at the discretion of the treating 
physician. 
 
Correlative samples:  
BM and PB should be collected on Cycle 1 Day 0 (C1D0), Cycle 1 Day 10 (C1D10)**, Cycle 1 Day 28 (C1D28), 
Cycle 2 Day 28 (C2D28)*** and Cycle 3 Day 28 (C3D28). A skin biopsy should be done on C1D0 (buccal swab may 
be substituted for skin if patient declines skin biopsy). A buccal swab should be done on C2D28. BM and PB should 
be collected at the time of progression (if possible).

BACKGROUND AND RATIONALE 
 
1.1 
Introduction  
 
Acute myeloid leukemia (AML) is an aggressive, relapsing blood cancer characterized by 
ineffective hematopoiesis and malignant expansion of clonal myeloid cells and a broad 
variety of genetically distinct sub-types1. 
 
Through next generation sequencing techniques, we have identified patterns of somatic 
mutations commonly associated with AML and found that these mutations organize into 
founding clones and subclones2.  
 
Treatment options for AML remain limited, and personalized strategies are needed1. The 
5-year overall survival among patients with AML age 25-64 is 40%3. Both clinical and 
genomic prognostic markers have been identified, including age, performance status, type 
of AML (de novo, AML with antecedent hematopoietic malignancy, or therapy-related 
AML), response to induction treatment and, most importantly, genetics4-7. 
 
Cytogenetic abnormalities have been one of the most important prognostic markers for risk 
stratification2. Specifically, patients with complex karyotype or monosomy karyotype are 
associated with adverse risk, and often carry mutations in TP538. In this population, 
standard cytotoxic chemotherapy and allogeneic stem cell transplantation result in 5-year 
survival of less than 10% and a median survival of only few months, and many patients 
even fail to achieve complete remission after induction chemotherapy5-7. 
 
We recently observed that AML and myelodysplastic syndrome (MDS) patients with TP53 
mutations have high response rates to decitabine8. In this study we will determine whether 
decitabine leads to an increase in overall survival in patients with TP53 mutated AML, who 
have detectable disease after initial induction chemotherapy. These patients represent the 
group with the poorest prognosis, and alternative therapy is desperately needed.   
 
1.2 
Study Rationale 
 
 
Among patients with complex or monosomy karyotypes, nearly 60% carry TP53 
mutations; whereas nearly all patients with TP53 mutations have complex or monosomy 
karyotypes, and these karyotypes almost always involve deletion of chromosome 5q, 
chromosome 7, chromosome 12, or chromosome 17p2,4,7,9. Patients with TP53 mutations 
tend to be older (median age 61 vs 54 years), have worse response to conventional 
chemotherapy (complete remission rate: 28% vs 50%), shorter event free survival (3-year 
EFS: 1% vs 13%), and overall survival (3-year OS: 3% vs 28%)7,9.  
 
We correlated response to decitabine with mutation status in 99 patients with AML or 
MDS. We observed response (complete remission (CR), complete remission with 
incomplete blood count recovery (CRi), or marrow complete remission (mCR) in 21/21 
patients with TP53 mutations. (p < 0.0001). No other gene mutation was associated with 


Version 10/01/2020, Amendment 8 
 
 11 of 63 
response in the 99 patients sequenced8 (Figure 1A).  
 
Consistent with this, we observed mutation clearance in all 16 cases with TP53 mutations 
evaluated at serial time points, and that TP53 mutations were cleared more quickly and 
consistently than other variants8 (Figure 2). 
 
 
 
Decitabine alone does not lead to a cure in the majority of responding patients. Mutation 
clearance is nearly always incomplete, and we could detect low levels of mutations (0.2 - 
5%) in 20 of 20 patients analyzed during remission with enhanced exome sequencing. 
Furthermore, in all 9 patients analyzed at relapse, the relapse occurred via subclonal 
evolution (expansion of a subclone that carries the founding clone mutations and additional 
mutations, suggesting that the founding clone mutations persisted during morphologic 
remission)8.  
 
Several clinical variables correlated with survival in this cohort: age, performance status 
(2 vs 0-1), and whether the patient underwent stem cell transplantation (Figure 3A). Thus, 
additional consolidation (e.g. hematopoietic cell transplantation) appears necessary to

decitabine.

achieve prolonged remissions. Importantly, in this cohort of patients who undergo 
decitabine induction, the presence of TP53 mutations no longer adversely affected survival 
following transplantation8.  
 
These data suggest that decitabine may have unique efficacy in patients with TP53 
mutations. In this study, we seek to determine whether decitabine therapy can improve 
outcomes, specifically overall survival, of this selected subset of AML patients with the 
poorest prognosis based on refractoriness to induction treatment and high-risk genetic 
mutations.

reads vs. the total number of reads at that nucleotide, and is proportional to the tumor burden. B and C. Mutation

1.3 
Investigational Agent 
 
Decitabine (5-aza-2’-deoxycitidine) is a DNA hypomethylating agent. Decitabine is an 
antimetabolite that can replace cytosine in DNA but, unlike cytosine, it cannot be 
methylated. The exact mechanism of decitabine activity has not been determined and may 
involve multiple pathways10-11. Decitabine is thought primarily to act by altering DNA 
methylation, a major mechanism for gene expression. Methylation of cytosine in the CpG 
dinucleotide by DNA methyltransferase leads to transcriptional silencing of genes during 
normal development and has emerged as a significant mechanism for the loss of tumor 
suppressor gene expression in human cancer, including AML12. Decitabine regulates DNA 
methylation (specifically targets the methyltransferase, DNMT1)13, effectively 
demethylating and reactivating different tumor suppressor genes. Other possible 
mechanisms for decitabine activity include cytotoxicity due to incorporation into DNA 
during S phase and formation of covalent adducts with DNA methyltransferase11-12. The 
irreversible inhibition and degradation of DNA methyltransferase 1 results in methylation-
independent induction of gene expression and it is associated with differentiation10. In 
addition to its differentiation inducing activity at low doses, decitabine has a direct 
cytotoxic effect at higher doses (1-2 µM)11-12.  
 
Decitabine has been investigated in hematologic malignancies using a range of doses and 
schedules.  Two dosing regimens are approved in the US compendium. A dose of 15 mg/m2 
every 8 hours for 3 days, based on a Phase III study in adults with MDS that demonstrated 
improved outcomes in the treatment arm compared to the supportive care arm14. And the 
dose of 20 mg/m2 daily for 5 days in 28-day cycles is also approved. 
 
In general, decitabine is well tolerated. Unlike conventional cytotoxic chemotherapy, 
decitabine can be administered in the outpatient setting. Cytopenias commonly result from 
AML/MDS inhibition of normal hematopoiesis, and often do not resolve until a complete 
response is achieved. Thus, neutropenic sepsis and thrombocytopenic bleeding remain 
significant problems regardless of therapy, especially during the first 4-8 weeks. In our 
experience treating elderly AML patients, neutropenia occurred in 24%, sepsis in 9%, and 
bacteremia in 7%.  Similar results have been observed in MDS patients14-16. As a result, 
death is not uncommon in the first 8 weeks of therapy, occurring in 15-17% of patients, 
and most commonly resulting from infection and cytopenias related to disease and therapy. 
While unsettling, these numbers are better than many historical patients treated with 
cytotoxic chemotherapy, and suggest a need for continued improvements in therapy. 
 
A. 
Pharmacokinetics and Metabolism of Decitabine 
 
In human subjects, after IV administration, decitabine displayed a distribution phase 
with a half-life of 7 minutes and a terminal phase elimination half-life of 10-35 
minutes as measured by bioassay17-20. The short plasma half-life is due to rapid 
inactivation of decitabine by deamination by liver cytidine deaminase17.  Total body 
clearance (Clp) in humans was high with a mean value of 126 mL/min/kg19. 
 
 
 


Version 10/01/2020, Amendment 8 
 
 14 of 63 
Among five adult patients with advanced solid tumors administered seven courses 
of 100 mg/m2 of decitabine by 1-hour infusions21, maximum plasma concentration 
ranged from 1 to 4 µM. Disappearance from plasma was biphasic with a rapid initial 
decline to less than 0.1 µM during the first hour post infusion and a slower decline 
over the next two hours to 6 nM, the level of detectability. Plasma half-life 
(mean±SE) was estimated to be approximately 7±1 minutes in the initial phase (t½α) 
and 35±5 minutes in the second phase (t½β). The area under the plasma 
concentration-time curve was 408±88 ng.hour/mL for these patients, with a peak 
plasma concentration of 2.01±0.44 µM (0.44±0.1 µg/mL), while mean volume of 
distribution (Vdss) and CLp was 4.59±1.42 L/kg and 126±21 mL/min/kg, 
respectively. The time course of DAC concentrations was similar in 1 of 2 patients 
administered 75 mg/m2, while DAC was usually undetectable in the plasma of 
patients administered 25 to 60 mg/m2. 
 
Using a longer infusion time (up to 40 hours), Rivard et al.18 reported a plasma 
concentration of 0.1 to 0.4 µg/mL. With infusion times of 40-60 hours, at an infusion 
rate of 1 mg/kg/h, plasma concentrations of 0.43-0.76 µg/mL were achieved. The 
steady-state plasma concentration at an infusion rate of 1 mg/kg/h was estimated to 
be 0.2-0.5 µg/mL. The half-life after discontinuing the infusion was 12-20 min17. 
 
Urinary excretion of unchanged decitabine was low, ranging from less than 0.01% to 
0.9% of the total dose, and there was no relationship between excretion and dose or 
plasma drug levels. High clearance values and a total urinary excretion of <1% of the 
administered dose suggest that decitabine is eliminated rapidly and largely by 
metabolic processes, including extrahepatic metabolism22. 
 
The steady state plasma concentrations (Css) ranged from 0.31 to 0.39 µg/mL (1.27 
to 1.60 µM) during the infusion of 100 mg/m² decitabine over a 6-hour period. The 
range of concentrations during a 600 mg/m2 infusion over an 8-hour period was 0.41-
16 µg/mL(1.68 to 4.76 µM)22. These plasma concentrations are in the same range 
as the in vitro concentrations that activated the expression of tumor suppressor gene 
p16 in three human non-small-cell lung cancer (NSCLC) cell lines21.  
 
Steady state decitabine levels of 0.1 to 0.2 µM were achieved in solid tumor patients 
dosed with 30 mg/m²/day and 40 mg/m²/day by continuous intravenous infusion 
over 72 hours22. 
 
Summary of published steady state serum levels are below and are in proportion to 
infusion rate (R2 = 0.98, p < 0.0001)23.

In our experience treating primary patient blasts in vitro, concentrations of 100 – 
500 nM are required to maximize methylcytosine reduction without causing 
cellular toxicity. Because decitabine incorporation into DNA is S-phase dependent, 
exposure of cells during cell division is necessary for efficacy. 
  
 
 
 
B. 
Experience with extended dosing schedules 
 
Decitabine does not act quickly and the median time to response is 3 months. 
Several doses have been tested and reported in the literature with doses ranging 
from 5 mg/m2/day for 5-10 days to doses of 135 mg/m2/day for 3 days23.  
 
From our experience8 and from another report24 there is data to support that lower 
doses over longer periods of time results in significant improvement in response 
rate and have lower toxicity. 
 
The mechanism underlying this observation is unclear, however there are some 
reports that suggest that at lower doses (e.g. 20 mg/m2), decitabine might promote 
cell differentiation through effective methylcytosine reduction and gene expression 
derepression, as opposed to induction of apoptosis via DNA damage that is seen at 


Version 10/01/2020, Amendment 8

higher doses (e.g. 100 mg/m2) and it is more typical of conventional 
chemotherapeutic agents25.  
 
Lower dose schedule (20 mg/m2/day) on days 1-5 became the standard strategy 
based on a series of studies.14,15,16 However, subsequent studies using longer dose 
schedules (days 1-10) found that this led to improved response rates.8,24 
 
Therefore, we will use a dose of 20 mg/m2/day as a 1-hour intravenous infusion on 
consecutive Days 1-10 in 28-day cycles, dose reductions for subsequent cycles will 
be allowed as described in Sections 5.1 and 6.3.

adequate for enrollment. (Refer to Appendix B for definition of TP53 mutant AML.) 
Alternatively, patients who have not had TP53 mutation analysis performed, but who 
have > 20% TP53 positive cells by immunohistochemistry detected on a bone marrow 
aspirate may also be enrolled,29 provided that mutation analysis is requested at the time 
of enrollment.

INVESTIGATION PLAN 
 
5.1 
Summary 
 
See Section 10 for synoptic table.  
 
Patients will receive decitabine 20 mg/m2/day as a 1-hour infusion on consecutive days 1-
10 of each 28-day cycle.  Decitabine dose will be calculated on baseline weight (obtained 
within a week of the start of cycle 1). Decitabine dose should be recalculated for weight 
changes above or below 10% from baseline weight 
 
Patients with clinical evidence of progressive disease or relapse (see Section 12 for 
definitions) should undergo a bone marrow biopsy to evaluate for progression.  
 
After 2 cycles, patients with progressive disease or relapse (a clear progression with at least 
>20% bone marrow blasts and an increase of at least 50% from prior biopsy) should be 
removed from protocol and proceed to salvage treatment according to center preference.  
 
Transplant eligible patients with PR after 3 cycles, may be removed from protocol and 
proceed to salvage treatment or transplant according to center preference. 
 


Version 10/01/2020, Amendment 8 
 
 21 of 63 
Transplant eligible patients with a suitable donor who achieve mLFS, CR, CRc, or CRi, 
may proceed to transplant after at 3 cycles (Section 5.5).  
 
Transplant ineligible patients with CR, CRc or CRi, PR will continue on maintenance doses 
(see below and Section 6.3) until progression or death, whichever occur first.  
 
Transplant ineligible patient with SD after cycle 4 may be removed from protocol and 
proceed to alternative treatment or continue on protocol according to treating physician’s 
preference.  
 
After Cycle 1, patients with blast counts < 5% may reduce decitabine dose from 20 
mg/m2/day x 10 days to 20 mg/m2/day x 5 days. 
 
For all other patients, after Cycle 2, decitabine administration dose will be decreased to 20 
mg/m2/day for 5 consecutive days (Days 1-5) every 28 days (unless otherwise specified) 
to limit myelosuppressive toxicity.  
 
Peripheral blood sampling and bone marrow biopsies with aspirate will be performed pre-
study, on Cycle 1 Day 10 ± 2, Cycle 1 Day 28 ± 4, on Cycle 2 Day 28 ± 4, on Cycle 3 Day 
28 ± 4, and at progression or relapse. Patients will provide a skin biopsy sample pre-study; 
a buccal swab can be performed for patients who decline skin biopsy. A buccal swab will 
be collected on Cycle 2 Day 28 ± 4.  
 
Following Cycle 3, bone marrow biopsies should be performed at the discretion of the 
treating physician to assess for response and for relapse or progression.  
 
If at any bone marrow collection the aspirate is a “dry tap”, two additional tubes of blood 
(10 mL each) will be collected and banked. 
 
A. 
Pre-study Procedures 
 
Pre-study procedures must take place no more than 28 days prior to the first dose 
of decitabine except where noted below. 
 
• Bone marrow aspirate and biopsy. Standard bone marrow procurement 
procedures will be followed for collection of the tissue. Assessments 
performed on bone marrow will include correlative studies, morphologic 
assessment, flow cytometry, cytogenetics, and FISH.  
• Bone marrow or peripheral blood for flow cytometry. 
• Collection and banking of bone marrow aspirate and peripheral blood. 
• Skin biopsy sample: Patients who decline to undergo a skin biopsy can 
provide a buccal swab as alternative. There is no required time frame for this 
sample; it may have been collected months or even years prior to the first 
dose of decitabine. If WBC at enrollment is > 30,000/µl, the skin biopsy 
should be collected at C1D28.

order to facilitate outcome follow-up. 
 
5.7 
Concomitant Therapy and Supportive Care Guidelines 
 
A. 
Chemotherapy 
 
Patients may be receiving hydroxyurea at enrollment and may continue on 
hydroxyurea through Cycle 2 of decitabine. An indication for hydroxyurea 
following 2 cycles of decitabine is evidence that the patient is not responding and 
decitabine should be discontinued. Other than decitabine, patients cannot receive 
chemotherapy during this trial.  
 
B. 
Growth Factors 
 
Erythroid growth factors should not be routinely administered to patients during the 
study. 
 
Thrombopoietin receptor agonists should not be routinely administered to patients 
during the study. 
 
Filgrastim (G-CSF) or sargramostim (GM-CSF) may be administered to patients 
with septic shock or febrile neutropenia at the discretion of the treating physician. 
 
C. 
Transfusions 
 
RBC transfusions and platelet transfusions will be administered at the discretion of 
the treating physician.  
 
D. 
Prophylactic Antimicrobial Agents  
 
Antimicrobial agents will be administered at the discretion of the treating physician. 
Common antimicrobial prophylaxis includes acyclovir, ciprofloxacin, and 
fluconazole. Alternative antibacterial and antifungal agents (e.g. voriconazole or 
posaconazole) may be used at the discretion of the treating physician. 
 
Administration of live or attenuated vaccination is not permitted. 
 
 
 


Version 10/01/2020, Amendment 8 
 
 27 of 63 
E. 
Radiotherapy 
 
Patients cannot receive radiotherapy within 14 days prior to study enrollment or 
while on study. 
 
 
F. 
Plasmapheresis or other anti-cancer therapy 
 
The use of plasmapheresis, other anti-cancer therapies, or other investigational 
agents is not permitted. 
 
5.8 
Duration of Therapy 
 
If at any time the constraints of this protocol are considered to be detrimental to the 
patient’s health and/or the patient no longer wishes to continue protocol therapy, the 
protocol therapy should be discontinued and the reason(s) for discontinuation documented 
in the case report forms. 
 
In the absence of treatment delays due to adverse events, treatment may continue until the 
start of conditioning therapy for transplant or, in transplant ineligible patients, treatment 
may continue indefinitely or until one of the following criteria applies: 
 
• Documented and confirmed disease progression 
• Death 
• Adverse event(s) that, in the judgment of the investigator, may cause severe or 
permanent harm or which rule out continuation of study drug 
• General or specific changes in the patient’s condition render the patient unable to 
receive further treatment in the judgment of the investigator 
• Suspected pregnancy 
• Serious non-compliance with the study protocol 
• Lost to follow-up 
• Patient withdraws consent 
• Investigator removes the patient from study 
• The Siteman Cancer Center decides to close the study 
 
Patients who prematurely discontinue treatment for any reason will be followed as 
indicated in the study calendar. 
 
5.9

Patients will be followed with regular office visits for at least 2 years since enrollment or 
until death, whichever occurs first.   
 
 
 
 


Version 10/01/2020, Amendment 8 
 
 28 of 63 
6.0 
DOSE DELAYS/DOSE MODIFICATIONS 
 
A criterion for discontinuation of the study is a delay of > 12 weeks between any two cycles.  
Dose delays and modifications are allowed as specified below. 
 
6.1 
Delay for Cytopenia or Infection 
 
As cytopenias are a defining feature of AML, their presence alone does not warrant dose 
modifications or delays. Patients will receive two cycles of therapy without adjustment for 
any cytopenia. Following Cycle 2, dose delays for cytopenias will be made at the discretion 
of the investigator in patients who have had significant infection complications.  
 
In patients with febrile neutropenia (temperature ≥ 38.5° with ANC < 1,000/µl) or systemic 
infections, treatment will be held at discretion of treating physician.  
 
In patients who experience significant infection complications during Cycle 1, Cycle 2 may 
be reintroduced with a 50% dose reduction (10 mg/m2/day for 10 consecutive days), or at 
full dose at the discretion of the investigator. 
 
6.2 
Delay for Organ Dysfunction 
 
If renal dysfunction (creatinine ≥ 3 X IULN) or hepatic dysfunction (bilirubin ≥ 2.5 mg/dl 
or ALT/AST ≥ 3 X IULN) occurs, therapy may not resume until the abnormalities have 
resolved to below the limits stated above. If renal or hepatic dysfunction occurs during a 
treatment course, the next dose of decitabine should be held, and serum chemistries should 
be checked twice per week.  Decitabine can be resumed at full dose when creatinine, 
bilirubin, ALT and AST are below the limits listed above.  
 
For grade 3-4 non-hematologic toxicities related to decitabine, decitabine treatment should 
be delayed until recovery to baseline or to grade ≤ 1. Decitabine may be reintroduced with 
a 50% dose reduction (10 mg/m2/day), or at full dose at the discretion of the investigator. 
 
6.3 
Modification in Dose or Schedule  
 
To limit myelosuppressive toxicity, Cycles 3 and beyond will consist of 20 mg/m2/day for 
5 consecutive days (Days 1-5). 
 
 
7.0 
REGULATORY AND REPORTING REQUIREMENTS 
 
The entities providing oversight of safety and compliance with the protocol require reporting as 
outlined below. 
 
Please refer to Appendix A for definitions and Appendix C for a grid of reporting timelines.  
Adverse events will be tracked from the time of consent until 30 days after the last dose of 
chemotherapy. Adverse events will be tracked from the time of consent until 30 days after the last

7.3 
Secondary Sites Reporting Requirements 
 
The research team at each secondary site is required to promptly notify the Washington 
University Sponsor-Investigator and designee of all serious adverse events (refer to 
Appendix A, Section D)  within 1 working day of the occurrence of the event or 
notification of the secondary site’s PI of the event.  This notification may take place via 
email if there is not yet enough information for a formal written report using an FDA Form 
3500a (MedWatch form) and Washington University’s Cover Sheet (Appendix C).  A 
formal written report must be sent to the Washington University Sponsor-Investigator and 
designee within 4 calendar days (for fatal or life threatening suspected adverse 
reactions) or 11 calendar days (for serious unexpected, suspected adverse reaction) of 
the occurrence of the event or notification of the secondary site’s PI of the event.  The death 
of a research participant that qualifies as a reportable event should be reported within 1 
working day of the occurrence of the event or notification of the secondary site’s PI of the 
event. 
 
The research team at a secondary site is responsible for following its site’s guidelines for 
reporting applicable events to its site’s IRB according to its own institutional guidelines. 
The research team at Washington University is responsible for reporting all applicable 
events to the FDA, and Janssen. 
 
7.4 
Reporting to Secondary Sites 
 
The Washington University Sponsor-Investigator (or designee) will notify the research 
team at each secondary site of all unanticipated problems involving risks to participants or 
others that have occurred at other sites within 10 working days of the occurrence of the 
event or notification of the Sponsor-Investigator (or designee) of the event.  This includes 
events that take place both at Washington University and at other secondary sites, if 
applicable.  Refer to Section 16.0 (Multicenter Management) for more information.

Reporting to Janssen  
 
A. 
Overview 
 
As the sponsor of the Study, the principal investigator shall be solely responsible 
for complying, within the required timelines, any safety reporting obligation to 
competent Health Authorities, IRB/ECs and any participating (co or sub) 
investigators, as defined in applicable laws and regulations.  For the purposes of 
this section, safety data includes adverse events, product quality complaints 
(PQCs), and special situations including pregnancies. 
 
The principal investigator will provide safety information to Janssen Scientific 
Affairs, LLC on adverse events, special situations including pregnancies and 
product quality complaints as defined within this section. 
 


Version 10/01/2020, Amendment 8 
 
 31 of 63 
B. 
Management of Safety Data 
 
This Study has been designated as an interventional study.  As such, all adverse 
events, special situations including pregnancies and product quality complaints will 
be reported  as described in this Exhibit from the time a subject has signed and 
dated an Informed Consent Form (ICF) until  30 days after the last documented use 
of a product under study within the study.  All subsequent AEs and SAEs will be 
collected after this period if the Principal Investigator considers the AE/SAE to be 
causally-related to the use of the study drug. 
 
For the purposes of this study, the J&J medicinal product is DACOGEN™ (decitabine).  
 
C. 
Hospitalization 
 
For reports of hospitalization, it is the sign, symptom or diagnosis which led to the 
hospitalization that is the serious event for which details must be provided. 
 
Any event requiring hospitalization or prolongation of hospitalization that occurs 
during the study must be reported as a serious adverse event, except hospitalizations 
for the following: 
 Hospitalizations not intended to treat an acute illness or adverse event (e.g., 
social reasons such as pending placement in long-term care facility) 
 Surgery or procedure planned before entry into the study. [Note: 
Hospitalizations that were planned before the start of data collection and 
where the underlying condition for which the hospitalization was planned 
has not worsened will not be considered serious adverse events. Any 
adverse event that results in a prolongation of the originally planned 
hospitalization is to be reported as a new serious adverse event.] 
 For convenience, the investigator may choose to hospitalize the subject for 
the duration of the treatment period. 
 
D. 
Maintenance of Safety Information and Procedure for 
Reporting  
 
All safety data should be maintained in a clinical database in a retrievable format. 
The principal investigator shall provide all adverse events, both serious and non-
serious, in report format. However, in certain circumstances more frequent 
provision of safety data may be necessary, e.g. to fulfill a regulatory request, and 
as such the data shall be made available within a reasonable timeframe at Janssen 
Scientific Affairs, LLC request. 
 
E. 
Procedures for Reporting Safety Data and Product Quality 
Complaints (PQCs) for Janssen Medicinal Products to Janssen Scientific 
Affairs, LLC 
 


Version 10/01/2020, Amendment 8 
 
 32 of 63 
All adverse events and special situations, whether serious or non-serious, related or 
not related, following exposure to a J&J medicinal product are to be documented 
by the investigator and recorded in the CRF and in the subject’s source records. 
Investigators must record in the CRF their opinion concerning the relationship of 
the adverse event to a J&J medicinal product.  
All (serious and non-serious) adverse events reported for a J&J medicinal product 
should be followed-up in accordance with clinical practice. 
 
F. 
SAEs, Adverse Events of Special Interest and Special Reporting 
Situations 
 
All serious adverse events that have not resolved by the end of the study, or that 
have not resolved upon discontinuation of the subject's participation in the study, 
must be followed until any of the following occurs: 
o The event resolves 
o The event stabilizes 
o The event returns to baseline, if a baseline value/status is available 
o The event can be attributed to agents other than the study drug or to factors 
unrelated to study conduct 
o It becomes unlikely that any additional information can be obtained (subject 
or health care practitioner refusal to provide additional information, lost to 
follow-up after demonstration of due diligence with follow-up efforts) 
 
The principal investigator will transmit all SAEs, Adverse Events of Special 
Interest, and special situations following exposure to a J&J product under study in 
a form provided by Janssen Scientific Affairs, LLC in accordance with Section 
7.5.L Transmission Methods, in English within 24-hours of becoming aware of 
the event(s). 
 
In the event the study is blinded, the principal investigator will submit an unblinded 
SAE or pregnancy exposure report to Janssen Scientific Affairs, LLC. 
 
All follow-up information for serious adverse events that are not resolved at the end 
of the study or by the time of patient withdrawal must be reported directly by the 
principal investigator, within 24 hours becoming aware, to Janssen Scientific 
Affairs, LLC using the Janssen Scientific Affairs, LLC Serious Adverse Event 
Report  
 
All available clinical information relevant to the evaluation of a related SAE, 
Adverse Events of Special Interest, serious ADR or special situation is required. 
 
• The principal investigator is responsible for ensuring that these cases are 
complete and if not are promptly followed-up. A safety report is not 
considered complete until all clinical details needed to interpret the case are 
received. Reporting of follow-up information should follow the same 
timeline as initial reports. 


Version 10/01/2020, Amendment 8 
 
 33 of 63 
 
• Copies of any and all relevant correspondences with regulatory authorities 
and ethics committees regarding any and all serious adverse events, 
irrespective of association with the J&J Product under study, are to be 
provided to Janssen Scientific Affairs, LLC using a transmission method in 
Section 7.5.L within 24 hours of such report or correspondence being 
sent to applicable health authorities. 
 
Special Reporting Situations 
Safety events of interest for a J&J medicinal product that require expediting 
reporting and/or safety evaluation include, but are not limited to: 
o Drug exposure during pregnancy (maternal and paternal) 
o Overdose of a J&J medicinal product  
o Exposure to a J&J medicinal product from breastfeeding  
o Suspected abuse/misuse of a J&J medicinal product 
o Inadvertent or accidental exposure to a J&J medicinal product  
o Any failure of expected pharmacological action (i.e., lack of effect) of 
a J&J medicinal product 
o Medication error involving a J&J medicinal product (with or without 
patient exposure to the J&J medicinal product, e.g., name confusion) 
o Suspected transmission of any infectious agent via administration of a 
medicinal product 
o Unexpected therapeutic or clinical benefit from use of a Janssen 
medicinal product 
 
These safety events may not meet the definition of an adverse event; however, from 
a Janssen Scientific Affairs, LLC perspective, they are treated in the same manner 
as adverse events. Special situations should be recorded on the Adverse Event page 
of the CRF. 
 
Any special situation that meets the criteria of a serious adverse event should be 
recorded on a Serious Adverse Event Report Form and be reported to Janssen 
Scientific Affairs, LLC within 24 hours of becoming aware of the event. 
 
G. 
Non-Serious AEs 
 
All non-serious adverse events should be reported to Janssen Scientific Affairs, 
LLC according to the timeframe outlined in the Research Funding Agreement 
section entitled Reporting of Data. 
 
 
 


Version 10/01/2020, Amendment 8 
 
 34 of 63 
H. 
Pregnancy  
 
Initial reports of pregnancy must be reported to Janssen Scientific Affairs, LLC by 
the principal investigator within 24 hours of becoming aware of the event using 
the Serious Adverse Event Form. Abnormal pregnancy outcomes (e.g. spontaneous 
abortion, fetal death, stillbirth, congenital anomaly, ectopic pregnancy) are 
considered serious adverse events and must be reported using the Serious Adverse 
Event Form.  
 
Any subject who becomes pregnant during the study must be promptly withdrawn 
from the study and discontinue further study treatment. 
 
Because the effect of the J&J medicinal product on sperm is unknown, pregnancies 
in partners of male subjects exposed to a J&J medicinal product will be reported by 
the principal investigator within 24 hours of their knowledge of the event using the 
Serious Adverse Event Form.  Depending on local legislation, this may require 
prior consent of the partner. 
 
Follow-up information regarding the outcome of the pregnancy and any postnatal 
sequelae in the infant will be required. 
 
I. 
PQC Reporting 
 
A PQC may have an impact on the safety and efficacy of the product. Timely, 
accurate, and complete reporting and analysis of PQC information from studies are 
crucial for the protection of patients, investigators, and Janssen Scientific Affairs, 
LLC, and are mandated by regulatory agencies worldwide. Janssen Scientific 
Affairs, LLC has established procedures in conformity with regulatory 
requirements worldwide to ensure appropriate reporting of PQC information. Lot 
and/or Batch #s shall be collected for any reports of failure of expected 
pharmacological action (i.e., lack of effect). The product should be quarantined 
immediately and if possible, take a picture. 
 
All initial PQCs involving a J&J medicinal product under study must be reported 
to Janssen Scientific Affairs, LLC by the principal investigator within 24 hours 
after being made aware of the event. The J&J contact will provide additional 
information/form to be completed. 
 
If the defect for a J&J medicinal product under study is combined with either a 
serious adverse event or non-serious adverse event, the principal investigator must 
report the PQC to Janssen Scientific Affairs, LLC according to the serious adverse 
event reporting timelines.  A sample of the suspected product should be maintained 
for further investigation if requested by Janssen Scientific Affairs, LLC.

Reporting to the FDA 
 
The conduct of the study will comply with all FDA safety reporting requirements.  
PLEASE NOTE THAT REPORTING REQUIREMENTS FOR THE FDA DIFFER 
FROM REPORTING REQUIREMENTS FOR HRPO/QASMC.  It is the 
responsibility of the Washington University principal investigator to report to the FDA as 
follows: 
 
• Report any unexpected fatal or life-threatening suspected adverse reaction (refer to 
Appendix A for definitions) no later than 7 calendar days after initial receipt of the 
information.   
• Report a suspected adverse reaction that is both serious and unexpected (SUSAR, refer 
to Appendix A) no later than 15 calendar days after it is determined that the information 
qualifies for reporting.  Report an adverse event (refer to Appendix A) as a suspected 
adverse reaction only if there is evidence to suggest a causal relationship between the drug 
and the adverse event, such as: 
o 
A single occurrence of an event that is uncommon and known to be 
strongly associated with drug exposure 
o 
One or more occurrences of an event that is not commonly associated with 
drug exposure but is otherwise uncommon in the population exposed to the drug 
o 
An aggregate analysis of specific events observed in a clinical trial that 
indicates those events occur more frequently in the drug treatment group than in a 
concurrent or historical control group 
• Report any findings from epidemiological studies, pooled analysis of multiple studies, 
or clinical studies that suggest a significant risk in humans exposed to the drug no later 
than 15 calendar days after it is determined that the information qualifies for reporting. 
• Report any findings from animal or in vitro testing that suggest significant risk in 
humans exposed to the drug no later than 15 calendar days after it is determined that the 
information qualifies for reporting.  
• Report any clinically important increase in the rate of a serious suspected adverse 
reaction of that listed in the protocol or IB within 15 calendar days after it is determined 
that the information qualifies for reporting. 
 
Submit each report as an IND safety report in a narrative format or on FDA Form 
3500A or in an electronic format that FDA can process, review, and archive.  Study 
teams must notify the Siteman Cancer Center Protocol Development team of each 
potentially reportable event within 1 business day after initial receipt of the 
information, and must bring the signed 1571 and FDA Form 3500A to the Siteman 


Version 10/01/2020, Amendment 8 
 
 37 of 63 
Cancer Center Protocol Development team no later than 1 business day prior to the 
due date for reporting to the FDA. 
 
Each notification to FDA must bear prominent identification of its contents (“IND 
Safety Report”) and must be transmitted to the review division in the Center for 
Drug Evaluation and Research (CDER) or in the Center for Biologics Evaluation 
and Research (CBER) that has responsibility for review of the IND.  Relevant 
follow-up information to an IND safety report must be submitted as soon as the 
information is available and must be identified as such (“Follow-up IND Safety 
Report”). 
 
7.7 
Exceptions to Expedited Reporting 
 
Events that do not require expedited reporting as described in include: 
• 
planned hospitalizations 
• 
respite care 
• 
events related to disease progression 
 
Events that do not require expedited reporting must still be captured in the EDC.

PHARMACEUTICAL INFORMATION 
 
8.1 
Study Drug Preparation  
 
OSHA Guidelines for handling cytotoxic drugs outlined in the American Journal of 
Hospital Pharmacy must be followed. 
 
Decitabine (5-aza-2’-deoxycytidine) is supplied as a lyophilized powder for injection, 50 
mg in 20-ml vials. When reconstituted with 10 ml of sterile water for injection, each ml 
will contain 5 mg of decitabine and 6.8 mg of KH2PO4. The reconstituted solution should 
be diluted to 0.1-1.0 mg/mL with pre-chilled 0.9% sodium chloride intravenous infusion, 
which has been cooled to 2-8oC. Reconstitution of the powder results in a rapidly 
decomposing solution. Unless used within 15 minutes of reconstitution, the diluted solution 
must be prepared using cold (2—8 degrees C) infusion fluids and stored at 2—8 degrees C 
(36—46 degrees F) for a maximum of 7 hours. 
 
Decitabine will be administered per dosing schedule every 28 ± 4 days.  
 
The site according to institutional drug disposal procedures should discard any partially 
used vials.  
 
Decitabine may be administered either as an inpatient or as an outpatient.  
 
Recommended safety measures for handling and preparation includes masks, protective 
clothing, gloves (double glove with nitrile gloves) and vertical laminar airflow safety

CORRELATIVE STUDIES 
 
9.1 
Correlative Studies Background 
 
A. 
Methylation Changes 
 
Decitabine causes hypomethylation of DNA by inhibiting DNA methyltransferase 
(Section 1.3). DNA methylation is an important epigenetic event in modulating 
development, cellular differentiation, and proliferation30-32. DNA methylation, 
primarily occurring at C5 of the cytosine ring within cytosine–guanine (CpG) 
dinucleotides, is frequently found clustered at gene regulatory sites such as 
promoter regions and results in transcriptional silencing of the affiliated gene. 
Depending on the promoter regions affected, DNA hypermethylation could lead to 
tumor suppressor gene silencing and ultimately tumorigenesis. 
 
B. 
Genome-wide decitabine induced DNA methylation signatures 
 
To determine whether decitabine treatment results in hypomethylation at consistent 
CpGs in AML blasts, we will perform whole genome bisulfite sequencing and 
assess for DNA methylation patterns in pre-treatment (Day 0), at Day 10 (C1D10), 
at Day 28 (C1D28), and in samples collected at relapse. 
  
C. 
Decitabine induced gene expression signatures 
 
To determine if changes in methylation induced by decitabine treatment correlate 
with gene expression changes, we will perform RNA sequencing on RNA extracted 
from bone marrow cells pre treatment  (Day 0), on Day 10 (C1D10), and on Day 
28 (C1D28) post decitabine. 
 
D. 
DNA Changes 
 
Conventional chemotherapies in AML cause early termination of DNA synthesis 
(cytarabine) or topoisomerase inhibition (daunorubicin) that ultimately converge 
onto TP53 that, together with CDKN2A sense irreparable DNA damage and 
ultimately trigger cell cycle arrest and cell death33. Therefore, it is not surprising 
that AML with defective TP53 are resistant to conventional chemotherapeutic 
agents. The effectiveness of decitabine that we observed in the cohort of patient 
with TP53 mutation suggests that decitabine acts through a different, TP53 
independent, mechanism. Interestingly, Tp53 null mice develop normally34, thus 


Version 10/01/2020, Amendment 8 
 
 39 of 63 
suggesting that cell cycle exit via differentiation is intact in these mice. As 
mentioned in Section 1, treatment with decitabine does not lead to clone 
eradication. Morphologic blast clearance precedes mutation clearance, with the 
malignant clone often remaining detectable at low levels over time (Figure 4).  
 
This is consistent with a model in which the proliferating cells of the malignant 
clone enter terminal differentiation after exposure to the drug, with the remaining 
quiescent stem cells carrying the mutation remaining dormant and eventually 
contributing to relapse when challenged to cycle.  
 
 
 
Figure 4: Kinetics of blast clearance versus clonal burden: bone marrow blast reduction detected by 
morphology at C1D28 does not correlate with founding clone reduction at the same time-point.  
 
Furthermore, difference in DNA methylation may not result in changes in gene 
expression34. For example, AMLs with mutations in DNMT3A that result in 
significant hypomethylation in specific DNA regions, do not display differences in 
whole transcriptome compared to AML bearing wild type DNMT3A36. This could 
be partially explained by the fact that DNA modifications (i.e. methylation status 
of gene promoters) are not the only determinant of gene transcription. Histones 
modifications, such as histones methylation, can alter chromatin structure through 
changes in the chemical moieties on the nucleosome surface and subsequently 
affect recruitment of the transcription factor machinery to specific DNA regions, 
silencing or activating gene transcription independently from promoter 
methylation. 
 
E. 
Decitabine induced myeloid differentiation 
 
To determine whether decitabine induces multilineage differentiation, or myeloid 
biased differentiation, we will identify cases where discordant morphologic blast 
clearance occurs without mutation clearance (Figure 4). We will flow sort 
differentiated peripheral blood monocytes, neutrophils, T cells, B cells, and NK 
cells and evaluate each population for the presence of AML-associated mutations. 
We compare results of samples sorted from Day 0, C1D28, C2D28, and C3D28, as 
appropriate. 


Version 10/01/2020, Amendment 8 
 
 40 of 63 
 
F. 
Correlation of the rate and depth of mutation clearance with 
survival 
 
We will assess tumor burden by allele frequency of patient-specific mutations in 
bone marrow or peripheral blood samples collected pre study, C1D28, C2D28 and 
C3D28 as well as at regular intervals after transplant. The velocity and depth of 
tumor response will be correlated to: 
 
• Achievement of clinical CR, 
• Time to best response, 
• Mutational status, 
• Time to disease progression 
 
9.2 
Correlative studies sample 
 
Samples should be identified with the patient UPN, the source (e.g. BM: bone marrow, PB: 
peripheral blood, S: skin; U: buccal), the cycle (e.g. D0: day 0; C1D10: cycle 1 day 10; 
C1D28; cycle 1 day 28, etc), the month/day/year of collection. Individual tubes or vials 
may be labeled with a specimen number. Specimen records should be included with each 
collection. 
 
Peripheral blood and bone marrow samples collected by collaborating institutions should 
be frozen as viable cells at 5-106 cells per ml.  For convenience, samples can be stored 
locally in liquid nitrogen and may be shipped in batches to Washington University for 
further processing, at the address below: 
Washington University 
Division of Oncology 
SWT621

12.1 
Response assessment  
 
Bone marrow biopsy will be obtained on Cycle 1 Day 28 ± 4, Cycle 2 Day 28 ± 4, and 
Cycle 3 Day 28 ± 4.  The cycle 2 Day 28 collection may be performed at the discretion of 
the treating physcian. 
 
All patients will be assessed for response according to the 2017 ELN AML 
Recommendations37: 
 
Complete remission (CR) – Defined as bone marrow blasts <5%; absence of circulating 
blasts and blasts with Auer rods; absence of extramedullary disease; absolute neutrophil 
count ≥1.0 x 109/L (1,000/μL); platelet count ≥100 x 109/L (100,000/μL). 
Complete remission with incomplete hematologic recovery (CRi): All CR criteria except 
for residual neutropenia - <1.0 x 109/L (1,000/μL) or thrombocytopenia -<100 x 109/L 
(100,000/μL) 
Cytogenetic complete remission (CRc) – Defined as morphologic complete remission plus 
a reversion to a normal karyotype. For this study, reversion of a normal karyotype is 
defined as no clonal abnormalities detected in a minimum of 20 mitotic cells. 
 
Morphologic leukemia free state (mLFS): Defined as bone marrow blasts <5%; absence of 
blasts with Auer rods; absence of extramedullary disease; no hematologic recovery 
required. Marrow should not merely be “aplastic”; at least 200 cells should be enumerated 
or cellularity should be at least 10% 
 
Partial remission (PR) – Defined as all hematologic criteria of CR; decrease of bone 
marrow blast percentage to 5% to 25%; and decrease of pretreatment bone marrow blast 
percentage by at least 50%.  
 
Stable Disease (SD) – Defined as not meeting the definitions of CR, CRi, PR, PD, or 
recurrence/morphologic relapse.   
 
 


Version 10/01/2020, Amendment 8 
 
 45 of 63 
Progressive disease (PD) – Defined as a clear increase in bone marrow blast count, 
typically a greater than 50% increase compared with baseline, or new extramedullary 
disease. Patients with a > 50% increase in peripheral blast count with an increase of the 
total peripheral white blood cell count to > 10,000/µl should undergo evaluation by bone 
marrow biopsy to access for progressive disease. Patients enrolled with a bone marrow 
blast count < 20% will have > 20% blasts and a > 50% increase compared with baseline. 
 
Recurrence/morphologic relapse - Defined as relapse following complete remission is 
defined as reappearance of blasts in the blood or the finding of ≥ 5% blasts in the bone 
marrow, not attributable to any other cause. New dysplastic changes is considered relapse. 
If there are no blasts in the peripheral blood and 5-20% blasts in the bone marrow, bone 
marrow biopsy should be repeated in > 1 week to confirm relapse. 
  
A. 
Duration of Response and Stable Disease, Treatment Failure, 
Overall Survival and Event-free Survival 
 
Duration of overall response:  The duration of overall response is measured from 
the time measurement criteria are met for CR or PR (whichever is first recorded) 
until the first date that recurrent or progressive disease is objectively documented 
 
The duration of overall CR is measured from the time measurement criteria are first 
met for CR until the first date that progressive disease is objectively documented.  
 
Duration of stable disease:  Stable disease is measured from the start of the 
treatment until the criteria for progression are met, taking as reference the smallest 
measurements recorded since the treatment started, including the baseline 
measurements.  
 
Treatment failure is defined as death or failure to achieve a complete or partial 
remission following 4 cycles of therapy. 
 
Overall survival is defined as the date of first dose of study drug to the date of death 
from any cause.  Patients still alive at the time of the final analysis will be right-
censored. 
 
Event-free survival is defined as the interval from the date of first dose of study 
drug to date of treatment failure, recurrence, death due to any cause, or loss to 
follow up. 
 
B. 
Duration of Remission and Relapse-free Survival for Patients 
Having Complete Remission 
 
Duration of complete remission is defined as the interval from the date that 
complete remission is documented to the date of recurrence, death due to any cause, 
or loss to follow-up.  
 


Version 10/01/2020, Amendment 8 
 
 46 of 63 
Relapse-free survival is defined only for those patients achieving a CR or CRi. It is 
defined as the interval from the date of first documentation of a leukemia-free state 
to the date of recurrence, death due to any cause, or loss to follow up.   
 
 
13.0 
DATA AND SAFETY MONITORING 
 
In compliance with the Washington University Institutional Data and Safety Monitoring Plan, an 
independent Data and Safety Monitoring Board (DSMB) will be specifically convened for this 
trial to review toxicity data.  .  A DSMB will consist of no fewer than 3 members including 2 
clinical investigators and a biostatistician.  DSMB members must be employed by Washington 
University, Barnes-Jewish  Hospital, or St. Louis Children’s Hospital.  Like investigators, DSMB 
members are subject to the Washington University School of Medicine policies regarding 
standards of conduct. Individuals invited to serve on the DSMB will disclose any potential 
conflicts of interest to the trial principal investigator and/or appropriate university officials, in 
accordance with institution policies. Potential conflicts that develop during a trial or a member’s 
tenure on a DSMC must also be disclosed.  
 
Until such a time as the first secondary site enrolls its first patient, a semi-annual DSM report to 
be prepared by the study team will be submitted to the Quality Assurance and Safety Monitoring 
Committee (QASMC) semi-annually beginning six months after study activation at Washington 
University (if at least one patient has been enrolled) or one year after study activation (if no patients 
have been enrolled at the six-month mark). 
 
The DSM report for the DSMB will be prepared by the study team with assistance from the 
statistician, will be reviewed by the DSMB, and will be submitted to the Quality Assurance and 
Safety Monitoring Committee (QASMC).  The DSMB must meet at least every six months 
beginning six months after study activation at Washington University or beginning six months 
after enrollment of the first patient at a secondary site, no more than one month prior to the due 
date of the DSM report to QASMC.  This report will include: 
 
• HRPO protocol number, protocol title, Principal Investigator name, data coordinator 
name, regulatory coordinator name, and statistician 
• Date of initial HRPO approval, date of most recent consent HRPO approval/revision, 
date of HRPO expiration, date of most recent QA audit, study status, and phase of study 
• History of study including summary of substantive amendments; summary of accrual 
suspensions including start/stop dates and reason; and summary of protocol exceptions, 
error, or breach of confidentiality including start/stop dates and reason 
• Study-wide target accrual and study-wide actual accrual including numbers from 
participating sites 
• Protocol activation date at each participating site 
• Average rate of accrual observed in year 1, year 2, and subsequent years at each

Until such a time as the first secondary site activates this protocol, a semi-annual DSM report to 
be prepared by the study team will be submitted to the QASM Committee beginning 6 months 
after study activation at Washington University. 
 
The study principal investigator and coordinator will monitor for serious toxicities on an ongoing 
basis. Once the principal investigator or coordinator becomes aware of an adverse event, the AE 
will be reported to the HRPO and QASMC according to institutional guidelines (please refer to 
Section 7.0).

AUDITING 
 
As coordinating center of this trial, Washington University (via the Quality Assurance and Safety 
Monitoring Committee (QASMC) will monitor each participating site to ensure that all protocol 
requirements are being met; that applicable federal regulations are being followed; and that best 
practices for patient safety and data collection are being followed per protocol.  Participating sites 
will be asked to send copies of all audit materials, including source documentation.  The audit 
notification will be sent to the Washington University Research Patient Coordinator, who will 
obtain the audit materials from the participating institution. 
 
Notification of an upcoming audit will be sent to the research team one month ahead of the audit. 
Once accrual numbers are confirmed, and approximately 30 days prior to the audit, a list of the 
cases selected for review (up to 10 for each site) will be sent to the research team. However, if 
during the audit the need arises to review cases not initially selected, the research team will be 
asked to provide the additional charts within two working days.

STATISTICAL CONSIDERATIONS 
 
15.1 
Study design and Sample size 
 
This will be an open-label single-arm phase II trial. The primary endpoint of this study is 
the 1-year overall survival (OS) which will be compared to historical data. TP53 mutations 
occur in 10-15% of patients with AML, and tend to occur in older adults3-6. Our power 
analysis suggests that we need at least 60 total patients enrolled. We anticipate that 500-
700 total AML patients will need to be available at enrolling institutions in order to reach 
the patient goal of 60. Time to complete accrual will be 24 months.  
 
15.2 
Analysis Populations 
 
Intent-to-Treat - Defined as all patients who receive at least one dose of decitabine.  
 
Efficacy-Evaluable - Defined as all patients who receive at least one cycle of treatment.   
 
Safety - Defined as all patients with at least one dose of decitabine. 
 
15.3 
Multicenter studies 
 
There are multiple centers in this study, however it is not anticipated that any center will 
accrue enough patients to warrant an analysis by center 
 
15.4 
Statistical Analysis 
 
A. 
Descriptive Analyses 
 
Patient Disposition: The number of patients discontinued, the reasons for 
discontinuation, and the number of cycles administered will be summarized. 
 
Demographics and Baseline Characteristics: Descriptive summary statistics will be 
provided for demographic and important baseline characteristics.  For continuous 
variables, the number of patients, mean, standard deviation, median, minimum and 
maximum will be provided.  For categorical variables, the number and percent of 
patients in each demographic/characteristic category will be summarized. 
 


Version 10/01/2020, Amendment 8 
 
 49 of 63 
B. 
Primary Endpoint Analysis 
 
The primary end-point of this phase II study is the 1-year survival in primary 
relapsed/refractory AML patients treated with decitabine. 
Overall survival (OS) is defined as the time from enrollment to death due to any 
cause.  For a patient who is not known to be alive at the end of study follow up, 
observation of OS is censored on the date the patient was last known to be alive 
(i.e. date of last contact). 
 
C. 
Overall survival analysis  
 
Kaplan-Meier curves depicting OS in the study population compared to historical 
control will be generated. Additionally, the median OS and the probability of OS 
from 1 month to the end of the follow-up period will be reported at pre-specified 
intervals. The associated 2-sided 90% CIs will be calculated using the 
complementary log-log transformation method (Collett 1994).  
 
D. 
Interim Analysis  
 
The estimated duration of the study is approximately 3 years from enrollment of 
the first patient to the final analysis. An interim analysis for OS will be performed 
at 1.5-year (where approximately one-fourth of patients will have at least 1-year 
follow-up if assuming uniform accrual) and the conditional power will be 
calculated for futility analysis based on the accumulated data. Conditional power is 
defined as the projected power to reject the null hypothesis (that treatment of TP53-
mutated AML patients with relapsed/refractory disease is associated with 1-year 
survival  of 25%) at the end of the study given the data accrued up to the interim 
analysis. Therefore, a small value of conditional power indicates a highly likely, if 
not inevitable, conclusion of negative finding given the current data. If conditional 
power of 0.3 or less is obtained at the interim analysis, an early termination due to 
futility will be recommended. 
 
E. 
Secondary Clinical Endpoints Analyses 
 
The principal measurement of toxicity will be a measure of the total number 
hospitalized days during the first 60 days of therapy. 
 
CRc rate will be analyzed based on the ITT population. The remission rate and its 
2-sided 90% confidence interval (CI) will be summarized.  
 
Event-free survival: EFS will be analyzed using Kaplan-Meier methodology and 
Kaplan-Meier plots will be provided using the ITT analysis set. The median EFS 
and its 2-sided 90% CI using the complementary log-log transformation method 
(Collett 1994) will be calculated.  
 
Leukemia-free survival: LFS will be analyzed using Kaplan-Meier methodology 


Version 10/01/2020, Amendment 8 
 
 50 of 63 
and Kaplan-Meier plots will be provided using the ITT analysis set. The median 
LFS and its 2-sided 90% CI using the complementary log-log transformation 
method (Collett 1994) will be calculated.  
 
Time to leukemia relapse: TTCR will be summarized using descriptive statistics. 
 
The time to stem cell transplant, the proportion of patients who are able to undergo 
transplantation, and the average number of hospital days during cycles 1 and 2, will 
also be documented. The association between response and clinical characteristics 
(morphologically evident disease -i.e., >5% blasts by cytomorphology- versus 
molecularly detected disease at the time of enrollment -i.e., disease detected with 
flow cytometry, cytogenetic, or mutational analysis with ≤ 5% blasts by 
cytomorphology-, de novo AML versus secondary AML versus treatment-related 
AML, presence versus absence of cytogenetic abnormalities in addition to TP53 
mutations, etc.) will be described using contingency tables and compared by Chi-
square test or Fisher’s exact test as appropriate. The association between survival 
(OS, EFS, LFS) and clinical characteristics will be described using Kaplan-Meier 
methods and compared by log-rank test. 
 
F. 
Secondary Molecular Endpoints Analyses 
 
Rate of patient specific mutation clearance after 28, and 56 days of therapy will 
be determined using an Illumina based platform. We will compare the rate of 
mutation clearance between the patients who achieve a CR/CRi after 4 cycles and 
those who do not. We anticipate that we will identify between 6 and 25 exonic 
SNVs per case (the range obtained with >200 AML samples sequenced to date with 
whole genome or exome sequencing), and that the expected 95% confidence 
interval of the mean variant allele frequency will be ±2.56% and ±1.25%, 
respectively, if we assume an anticipated standard deviation of 3.2% within the 
same clone. The change of tumor burden over time and its association with clinical 
response will be assessed using 2-way ANOVA for repeated measurement data, 
followed by the ad-hoc multiple comparisons for between-group differences (e.g., 
responders vs. non-responders) at given time points as well as the between-time 
differences within each group. The resultant critical P values will also be corrected 
using permutation analysis for multiple testing. 
 
The percent decrease in bone marrow methylcytosine will be calculated on day 
10±1. We will compare this reduction with previously published data and between 
the patients who achieve CR/CRi and those who do not. The correlation of peak 
plasma levels of decitabine with response will be assessed using 2-sample t-test or 
Mann-Whitney non-parametric rank-sum test as appropriate. The change of total 
bone marrow DNA methylcytosine from baseline and its association with both 
steady-state plasma drug levels and response will be assessed using 2-way ANOVA 
for repeated measurement data, followed by the ad-hoc multiple comparisons for 
between-group differences (e.g., responders vs. non-responders) and between-time 


Version 10/01/2020, Amendment 8 
 
 51 of 63 
differences. Similar analyses will be performed for the correlation of expression 
profiles and SNP analysis with pharmacokinetic data.   
 
The proportion of patients who achieve mutation clearance to <0.1%, after 3 cycles 
of decitabine, will be calculated and its 2-sided 90% confidence interval (CI) will 
also be provided. Using a sensitive sequencing technology such as Haloplex, the 
sensitivity of PB or BM for detecting residual mutation burden, as well as the TP53 
clonal burden reduction after consolidation with stem cell transplantation will be 
summarized using contingency tables. 
 
G. 
Statistical Power Justification 
 
Primary endpoint. The primary endpoint of this study is the 1-year overall survival 
(OS) which will be compared to historical data (1-year OS=25%). Assuming 
survival times following an exponential distribution and an additional 1-year 
follow-up period after the accrual period, a total of 60 patients will be enrolled and 
this allows us 85% power at 1-sided alpha=0.05 to detect 15% difference (40% vs. 
25%) in 1-year OS.  
 
Secondary endpoints.  A power analysis was performed using two-sample t-test 
for between-group difference and paired t-test for the change over time. For tumor 
clearance, this will provide > 99% power to detect a 10% difference in the means 
at two separate time points for clones with 6 or more variants, and > 98% power to 
detect a 15% difference if there are 3 or more variants per clone with α = 0.05 
(power will decrease to 91% and 82%, respectively, in cases where the standard 
deviation is 4.7%, the maximum we have observed thus far). For pharmacologic 
correlations, we anticipate 85% power to determine a 25 ng/ml difference between 
the average Cmax of 45 evaluable responders and 55 evaluable non-responders with 
an anticipated average Cmax of 70 ng/ml and a standard deviation of 40 ng/ml 
within the entire cohort, and with α = 0.05. We believe a less significant difference 
would not be sufficient to warrant application in clinical decision making (i.e. 
whether to continue therapy for more than 1 cycle). We anticipate 99% power to 
determine a difference of 20% in the reduction of bone marrow methylcytosine 
between 45 evaluable responders and 55 evaluable non-responders with an 
expected standard deviation of 15% and α = 0.05. The difference in methylcytosine 
reduction previously observed was 30% between patients achieving CR/PR and 
those with only hematologic improvement.

MULTICENTER REGULATORY REQUIREMENTS 
 
Washington University requires that each participating site sends its informed consent document 
to be reviewed and approved by the Washington University Regulatory Coordinator (or designee) 
prior to IRB/IEC submission.    
 


Version 10/01/2020, Amendment 8 
 
 52 of 63 
Site activation is defined as when the secondary site has received official written documentation 
from the coordinating center that the site has been approved to begin enrollment.  At a minimum, 
each participating institution must have the following documents on file at Washington University 
prior to study activation: 
• Documentation of IRB approval of the study in the form of a letter or other official 
document from the participating institution’s IRB.  This documentation must show which 
version of the protocol was approved by the IRB. 
• Documentation of IRB approval of an informed consent form. The consent must include 
a statement that data will be shared with Washington University, including the Quality 
Assurance and Safety Monitoring Committee (QASMC), the DSMC (if applicable), and 
the Washington University study team. 
• Documentation of FWA, signed FDA Form 1572 (if applicable), and the CVs of all 
participating investigators. 
• Protocol signature page signed and dated by the investigator at each participating site.

Version 10/01/2020, Amendment 8 
 
 55 of 63 
APPENDIX A: Definitions for Adverse Event Reporting  
 
Definition: An adverse event is any untoward medical occurrence in a clinical study subject 
administered a medicinal (investigational or non-investigational) product. An adverse event does 
not necessarily have a causal relationship with the treatment. An adverse event can therefore be 
any unfavorable and unintended sign (including an abnormal finding), symptom, or disease 
temporally associated with the use of a medicinal (investigational or non- investigational) 
product, whether or not related to that medicinal (investigational or non-investigational) product. 
(Definition per International Conference on Harmonisation [ICH]). 
 
This includes any occurrence that is new in onset or aggravated in severity or frequency from the 
baseline condition, or abnormal results of diagnostic procedures, including laboratory test 
abnormalities. 
 
Grading: the descriptions and grading scales found in the revised NCI Common Terminology 
Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all toxicity reporting.  A copy 
of the CTCAE version 4.0 can be downloaded from the CTEP website. 
 
Attribution (relatedness), Expectedness, and Seriousness: the definitions for the terms listed 
that should be used are those provided by the Department of Health and Human Services’ Office 
for Human Research Protections (OHRP).  A copy of this guidance can be found on OHRP’s 
website: 
http://www.hhs.gov/ohrp/policy/advevntguid.html 
 
All serious adverse events (SAE) that occur within 30 days of the last dose of therapy will be coded 
using NCI CTCAE v. 4.0.  Grade 3-5 laboratory abnormalities will only be considered if they do 
not resolve within 7 days. The incidence of treatment-emergent adverse events (number and 
percent of patients reporting the adverse event at least once during the study) will be summarized.  
In addition, adverse events will be summarized by investigator attribution of relationship to study 
medication and by grade. 
 
A. 
Serious Adverse Event (SAE)  
 
Definition of SAE:  any adverse drug experience that results in any of the following 
outcomes and is unrelated to infection, bleeding, or a transfusion reaction: 
• Death 
• A life-threatening  
• Inpatient hospitalization or prolongation of existing hospitalization  
• A persistent or significant disability/incapacity (i.e., a substantial disruption of a 
person’s ability to conduct normal life functions) 
• A congenital anomaly/birth defect 
• A suspected transmission of any infectious agent via a medicinal product 
• Any other experience which, based upon appropriate medical judgment, may 
jeopardize the subject and may require medical or surgical intervention to prevent 
one of the outcomes listed above 
• It is medically important * 


Version 10/01/2020, Amendment 8 
 
 56 of 63 
 
*Medical and scientific judgment should be exercised in deciding whether expedited 
reporting is also appropriate in other situations, such as important medical events that 
may not be immediately life threatening or result in death or hospitalization but may 
jeopardize the subject or may require intervention to prevent one of the other outcomes 
listed in the definition above. These should usually be considered serious. 
 
NOTE: DEATH FOR ANY REASON SHOULD BE REPORTED AS A SERIOUS 
ADVERSE EVENT. 
 
B. 
Adverse Events of Special Interest (AESI) 
 
Definition of Adverse Events of Special Interest  
Adverse events of special interest are events that Janssen Scientific Affairs, LLC is 
actively monitoring as a result of a previously identified signal (even if non-serious).  
No adverse events of special interest will be collected for this study.  
 
C. 
Unexpected Adverse Experience/Reference Safety Information 
 
Definition: an adverse event  is considered unlisted if the nature or severity is not 
consistent with the applicable reference safety information.  current investigator brochure 
(or risk information, if an IB is not required or available). For a medicinal product(s) with 
a marketing authorization, the expectedness of an adverse event will be determined by 
whether or not it is listed in the applicable Package Insert..  
 
https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=deb4a13c-855b-4372-9778-
6e81da598df6 
D. 
Life-Threatening Adverse Experience  
 
Definition: any adverse drug experience that places the subject (in the view of the 
investigator) at immediate risk of death from the reaction as it occurred, i.e., it does not 
include a reaction that, had it occurred in a more severe form, might have caused death. 
Disease progression should not be recorded as an adverse event or serious adverse event 
term.  
 
E. 
Unanticipated Problems 
 
Definition: 
 
• unexpected (in terms of nature, severity, or frequency) given (a) the research 
procedures that are described in the protocol-related documents, such as the IRB-
approved research protocol and informed consent document; and (b) the 
characteristics of the subject population being studied; 
• related or possibly related to participation in the research (“possibly related” means 
there is a reasonable possibility that the incident, experience, or outcome may have 
been caused by the procedures involved in the research); and 


Version 10/01/2020, Amendment 8 
 
 57 of 63 
• suggests that the research places subjects or others at a greater risk of harm 
(including physical, psychological, economic, or social harm) than was previously 
known or recognized 
 
F. 
Product Quality Complaint (PQC) 
 
A product quality compliant is defined as any suspicion of a product defect related to a 
potential quality issue during manufacturing, packaging, release testing, stability 
monitoring, dose preparation, storage or distribution of the product, or delivery system.  
Not all PQCs involve a subject.  Lot and batch numbers are of high significance and need 
to be collected whenever available. 
 
Examples of PQC include but not limited to: 
• Functional Problem: e.g., altered delivery rate in a controlled release product 
• Physical Defect:  e.g. abnormal odor, broken or crushed tablets/capsules 
• Potential Dosing Device Malfunction: e.g., autoinjector button not working, needle 
detaching from syringe 
• Suspected Contamination 
• Suspected Counterfeit 
 
G. 
Noncompliance 
 
Definition: failure to follow any applicable regulation or institutional policies that govern 
human 
subjects 
research 
or 
failure 
to 
follow 
the 
determinations 
of 
the 
IRB.  Noncompliance may occur due to lack of knowledge or due to deliberate choice to 
ignore regulations, institutional policies, or determinations of the IRB. 
 
H. 
Serious Noncompliance 
 
Definition: noncompliance that materially increases risks, that results in substantial harm 
to subjects or others, or that materially compromises the rights or welfare of participants. 
 
I. 
Protocol Exceptions 
 
Definition: A planned deviation from the approved protocol that are under the research 
team’s control. Exceptions apply only to a single participant or a singular situation. 
 
Local IRB pre-approval of all protocol exceptions must be obtained prior to the event.  For 
secondary sites, the Washington University PI will issue approval of the exception, but it 
must also be submitted to the local IRB with documentation of approval forwarded to 
Washington University.  Washington University IRB approval is not required for protocol 
exceptions occurring at secondary sites. 
 
  
 
 


Version 10/01/2020, Amendment 8 
 
 58 of 63 
APPENDIX B: Definition of TP53 Mutant AML 
 
A patient with TP53 mutant AML is defined as having a minimum variant allele frequency of 10% 
identified with at least 50 total reads and 5 variant reads. If a germline sample was sequenced, the 
variant reads must have a Fisher exact test p value < 0.01 when compared with the leukemia 
sample. If a germline sample was not available for sequence comparison, the TP53 variant must 
be described in Cosmic and not identified in dbGaP as a germline variant in > 0.1% of the 
population.

This consent form describes the research study and helps you decide if you want to participate.  It 
provides important information about what you will be asked to do during the study, about the risks and 
benefits of the study, and about your rights and responsibilities as a research participant. By signing this 
form, you are agreeing to participate in this study. 
• You should read and understand the information in this document including the procedures, 
risks and potential benefits.  
• If you have questions about anything in this form, you should ask the research team for more 
information before you agree to participate.   
• You may also wish to talk to your family or friends about your participation in this study. 
• Do not agree to participate in this study unless the research team has answered your 
questions and you decide that you want to be part of this study.  
 
KEY INFORMATION 
This is a research study conducted by Dr. John Welch having to do with using the drug decitabine to 
treat patients who have acute myeloid leukemia (AML) and a mutation in a gene called TP53. TP53 is a 
gene that, if mutated (changed), can fail to function normally in AML.  It is a gene which helps to 
prevent cancer, and the current standard treatments for AML do not work well in leukemias that have 
TP53 mutation.  You are invited to be in this study because you have AML with a mutation in your 
TP53 gene, and you have recurrent or resistant disease after receiving the standard treatment. You 
should carefully consider the information in this consent document and discuss it with the research team. 
You should understand why you might want to participate, or why you might not want to participate. It 
is your choice whether to participate or not. 
 
If you agree and sign this consent, you will be volunteering to participate in the research study. The 
research team must give you a copy of this signed consent document. 
 
1. What is the research study about?  
The purpose of this research study is to determine if we can overcome TP53 malfunction with use of 
a drug called decitabine. Decitabine is approved by the U.S. Food and Drug Administration (FDA) 
for the treatment of myelodysplastic syndrome (another disease involving dysfunctional blood cells) 
and some forms of leukemia. We will perform detailed genetic testing to help us better understand 
how and why decitabine works when TP53 mutation is present. 
 
2. Why should I consider participating? 
The current standard treatments for AML do not work well in leukemias that have TP53 mutation, 
and acute leukemias with mutations in this gene behave aggressively and tend to have a worse

outcome compared to leukemias that do not have this mutation. The purpose of this research study is 
to determine if we can overcome TP53 malfunction with use of a drug called decitabine.  
 
3. What will I be asked to do? 
You will receive treatment with decitabine as an IV infusion on a 28-day cycle. During Cycles 1 and 
2, it will be given on Days 1 through 10 of each cycle. People who continue on to Cycle 3 will 
receive decitabine on Days 1 through 5 of that cycle and any subsequent cycles. The number of 
cycles of decitabine you receive will depend on your response to treatment, which is assessed by 
bone marrow aspirate and biopsy at the end of each cycle. We will collect additional bone marrow 
aspirate and blood for research purposes at each of these time points. A skin biopsy or buccal swab 
(a procedure during which you scrape the inside of your cheek with a small wooden stick) will be 
performed at the end of Cycle 2.  
 
This study includes some procedures you might have for your care if you weren’t in this study, such 
as regular physical exams, and blood draws to monitor your counts and organ function.  When you 
come to the clinic for your study visits, you may be here for a short amount of time (less than an 
hour if you’re just having blood drawn) or a longer amount of time (up to several hours if you’re 
receiving decitabine or having a bone marrow aspiration). The length of your involvement in this 
study will depend on your response to decitabine treatment and whether you undergo a stem cell 
transplant.  You will receive at least 2 months of treatment with decitabine and will have data 
collected on your health and disease status for 2 years after you come off treatment. 
 
You may choose to stop participating and withdraw from the study at any time. If you withdraw 
from the study, the research team may continue to use the information already collected about you.   
 
4. What are the risks? 
There are some risks to you if you agree to volunteer for this study. The most common risks are low 
white blood cells (which could increase your risk of infection), low platelets (which could increase 
your risk of bleeding), low red blood cells, fatigue, and pneumonia. The risks to you are described in 
more detail later in this consent document.  
 
5. What are the benefits to me? To others? 
There may be no direct benefit to you. However, we hope that in the future, other people might 
benefit from this study because it will help researchers learn more about how to treat AML with 
TP53 mutation. 
 
6. Is there any financial cost to me? 
As part of this study you will receive tests and procedures that are similar to what you would receive 
during routine clinical care of your AML. Your health plan/insurance company will be billed for 
some or all of these costs, and you will be responsible for any co-pays and deductibles that are 
normally required by your health plan/insurance. 
 
7. Will my information be confidential? 
Yes, your identity will be kept confidential. Your information will be available only to those who are 
working on this study.

8. Who is the sponsor? 
The study is sponsored by Washington University School of Medicine. The National Institutes of 
Health (NIH) and Janssen Pharmaceuticals are funding this research study.   
 
WHAT IS THE PURPOSE OF THIS STUDY? 
This is a research study.  We invite you to participate in this research study because you have acute 
myeloid leukemia (AML) with a mutation in a gene called TP53 and have recurrent or resistant disease 
after receiving the standard treatment.  AML is a type of cancer that makes your white blood cells grow 
fast and abnormally. Genes are a unique combination of molecules (called DNA) that we inherit from 
our parents. There are millions of tiny differences in our genes that determine things like our height or 
the color of our eyes. Some of these differences may make some people more or less likely to develop 
certain diseases or conditions or to have certain characteristics.  TP53 is a gene that, if mutated 
(changed), can fail to function normally in AML.  It is a gene which helps to prevent cancer, so it is not 
surprising that acute leukemias with mutations in this gene behave aggressively and tend to have a worse 
outcome compared to leukemias that do not have this mutation.  The current standard treatments for 
AML do not work well in leukemias that have TP53 mutation.   
 
The purpose of this research study is to determine if we can overcome TP53 malfunction with use of a 
drug called decitabine.  We will perform detailed genetic testing to help us better understand how and 
why decitabine works when TP53 mutation is present. 
 
Decitabine is approved by the U.S. Food and Drug Administration (FDA) for the treatment of 
myelodysplastic syndrome (another disease involving dysfunctional blood cells) and some forms of 
leukemia.  Although the National Comprehensive Cancer Network (NCCN) recognizes decitabine as a 
standard treatment for patients over the age of 60 with AML, it is not approved by the FDA for the 
treatment of AML, so it is considered investigational as used in this study. 
 
WHAT WILL HAPPEN DURING THIS STUDY? 
All treatment will be given in either the outpatient or inpatient setting at Siteman Cancer Center.  We 
feel it is important to remind you that any procedures regardless of whether they are tests you would 
have if you did not take part in the research or are research-related will require you to remain at the 
Siteman Cancer Center up to several hours to complete the necessary testing.  There may also be a wide 
variability in the length of clinic visits due to the unique characteristics of your medical history and 
health condition as well as due to clinic factors such as physician availability, staffing shortages, and 
weather delays.  This will also vary depending upon your needs at the visit as determined by your 
physician.  It is important that you are able to be available to complete the procedures at each visit to 
ensure that your safety and treatment needs are met. 
 
Before you begin study treatment: 
You will need to have the following screening exams, tests, or procedures to find out if you can continue 
to be in the study.  Most of these procedures are part of regular cancer care and may be done even if you 
do not join the study.  If you have had some of them recently, they may not need to be repeated.  This 
will be up to your study doctor. 
• Physical exam, including taking of vital signs, reviewing your medical history, and talking about 
any symptoms or health problems you’re having

• Blood tests to check your blood counts and organ function (approximately 2 teaspoons of blood 
will be drawn) 
• Blood tests to make sure you don’t test positive for hepatitis or HIV 
• Urine pregnancy test if you are a woman of childbearing potential 
• Collection of blood for research purposes (approximately 2 teaspoons of blood will be drawn) 
 
It is possible that after your medical history, tests, and procedures are reviewed, you will not be able to 
continue in this study.  If this occurs, your study doctor will go over the reasons with you. 
 
Procedures throughout the study: 
If you are eligible to continue participating, you will begin receiving treatment with decitabine.  
Decitabine is given as an IV infusion on a 28-day cycle.  During Cycles 1 and 2, it will be given on Days 
1 through 10 of each cycle.  People who continue on to Cycle 3 will receive decitabine on Days 1 
through 5 of that cycle and any subsequent cycles.  The number of cycles of decitabine you receive will 
depend on your response to treatment, which is assessed by bone marrow aspirate and biopsy at the end 
of each cycle. 
• At the end of Cycle 2, people whose disease has progressed or relapsed will be removed from 
this study and will go on to receive another treatment. 
• At the end of Cycle 3: 
o People who are eligible to have a stem cell transplant and whose disease has had a complete 
response to treatment will go on to conditioning and transplant. 
o People who are eligible to have a stem cell transplant but whose disease has not had a 
complete response to treatment will be removed from this study and will go on to receive 
another treatment. 
o People who are not eligible to have a stem cell transplant will continue to receive decitabine 
on a maintenance schedule. 
• At the end of Cycle 4, people whose disease is stable may be removed from this study in order to 
receive another treatment or may stay on this study depending on their doctor’s preference. 
 
You will have the following tests and procedures during your participation in this study: 
• Physical exam, including taking of vital signs, reviewing your medical history, and talking about 
any symptoms or health problems you’re having (Day 1 of each cycle) 
• Blood tests to check your blood counts (weekly and at the end of each cycle) (approximately 1 
teaspoon of blood will be drawn) 
• Blood tests to check your organ function (Day 1 of each cycle – more frequently if your doctor 
decides it’s necessary) (approximately 1 teaspoon of blood will be drawn) 
• Bone marrow aspirate and biopsy to check the status of your disease; at each time point, 
additional bone marrow will be taken for research purposes (including genetic research) (at the 
end of Cycles 1, 2, and 3, and if your disease progresses or relapses). If we are unable to obtain a 
sample from the bone marrow aspirate, two additional tubes of blood (10 mL each) will be 
collected. 
• Patients at Washington University in St. Louis will undergo a bone marrow aspirate and biopsy 
on Day 10 of Cycle 1. 
• Collection of blood for research purposes (at the same time as each bone marrow aspirate and

biopsy) 
• Buccal swab for research purposes (Cycle 2 Day 28) 
 
One goal of the present study is to identify/study genetic factors relating to how your disease responds to 
study treatment. We would like to study changes in your DNA to understand how decitabine turns on 
and off genes and how this impacts leukemia response to therapy.  We will also compare the genetic 
material from your cancer tissue to the genetic material from your normal tissue (which we obtain from 
your skin biopsy or buccal swab) to find the differences that exist. 
 
At the end of your participation, you will have the following tests and procedures: 
• Physical exam, including taking of vital signs, reviewing your medical history, and talking about 
any symptoms or health problems you’re having 
• Blood tests to check your blood counts and organ function 
• Bone marrow aspirate and biopsy to check the status of your disease 
 
Follow-up procedures: 
You will be followed for 30 days after the last dose of decitabine to check for side effects and response.  
After that, data will be collected from your medical record for up to 2 years after your last dose of 
decitabine on any additional treatments you receive, your response to treatment and the status of your 
disease, and your health status in general. 
 
To help us better understand how and why decitabine works when TP53 mutation is present, we will 
perform whole genome sequencing on the research samples collected from you. No results from the 
research related genetic testing will be made available to you because the testing/sequencing is taking 
place in a research lab, not a clinical lab with rigorous certified procedures for verifying and reporting 
results. We would be unable to provide you with any certainty that the results were accurate. As it would 
not be recommended that you rely on the results to take any action with regards to your healthcare we 
will not be returning this information to you. 
 
Will you save my samples or research data to use in future research studies?  
As part of this study, we are obtaining blood, bone marrow, and data from you. We would like to use 
this blood, bone marrow, and data for studies going on right now as well as studies that are conducted in 
the future.  Your blood, bone marrow, and data may also be used for broad sharing throughout the 
research community. This means your blood, bone marrow, and data may be used for any sort of 
research and not just research related to your current condition, including research to develop 
investigational tests, treatments, drugs or devices that are not yet approved by the U.S. Food and Drug 
Administration.  These researchers may be at Washington University, at other research centers and 
institutions, or commercial sponsors of research. It is unlikely that what we learn from these studies will 
have a direct benefit to you.  There are no plans to provide financial compensation to you should this 
occur.  By allowing us to use your blood, bone marrow, and data you give up any property rights you 
may have in the blood, bone marrow, and data. 
 
One way in which we may share your data with others is by putting it into a large database of 
information, called a data repository.  If your data is placed in one of these repositories it will be placed 
in the “controlled-access” portion of the repository. This means that only qualified researchers, who

have received permission from individuals that monitor the access to and use of the data, will be able to 
look at and use your information.  Before we put it in this repository, we will remove any information, 
such as your name and birthdate, that might easily identify you.  Even though these data will not have 
your name or other identifying information associated with it, it is still possible that someone may be 
able to trace these data back to you because genetic information is unique.  Although your individual 
data will only be in the controlled access database certain summary information may be available to the 
general public. 
 
Future research with your donated blood and bone marrow may include the study of genetic factors 
relating to AML.  This future research may focus on one or more genes to study the differences in 
specific genes or small groups of genes in people who have AML when compared to people who do not 
have AML.  Future research with your blood and bone marrow may also attempt to sequence large parts 
of your genome or even your entire genome.  These types of sequencing provide detailed descriptions of 
your DNA and result in the creation of information that is as unique to you as your fingerprint. 
 
If you change your mind and do not want us to store and use your blood, bone marrow, and data for 
future research, you should contact the research team member identified at the top of this document.  
The blood, bone marrow, and data will no longer be used for research purposes. However, if some 
research with your blood, bone marrow, and data has already been completed, the information from that 
research may still be used. Also, if the blood, bone marrow, and data has been shared with other 
researchers it might not be possible to withdraw the blood, bone marrow, and data to the extent it has 
been shared.

Testing for Reportable Diseases 
If you decide to participate in this study, we will test you for HIV and hepatitis B and C.  The results of 
this test could indicate that you have HIV or hepatitis B or C.  If that happens, we will refer you to a 
doctor who specializes in treating HIV or hepatitis B or C.  We will make every effort to keep your 
personal information confidential.  However, we are required by law to report positive tests to the state 
of Missouri and/or local agencies.  Becoming aware of a diagnosis of HIV or hepatitis B or C could have 
serious personal and/or social consequences, including difficult obtaining health insurance or 
employment.  For more information about the risks of HIV and hepatitis B and C testing, please talk to

It is likely that you will experience discomfort or pain, redness, swelling, and bruising at the site of the 
needle insertion. It is less likely that you will experience bleeding from the site of the needle insertion. 
There is a rare chance (approximately less than 1/100) of developing a significant infection or bleeding 
from this procedure. An allergic reaction to the anesthetic may occur. A scar may form at the site of 
needle entry. 
 
Risks of Skin Biopsy 
You will experience discomfort at the site of the biopsy. You may rarely experience bleeding and 
infection. 
 
Risks of Local Anesthesia 
You may likely experience pain at the injection site.  There is a rare risk that you will experience nausea, 
rash, or inflammation at the injection site. 
 
Risks of Buccal Swab 
To obtain some normal cells, you may be asked to use a small stick to gently swab the inner surface of 
your cheek. You may feel some pressure as you swab your cheek, but it should not produce any other 
discomfort or side effects. 
 
Risks for Women Capable of Becoming Pregnant 
If you are a woman capable of becoming pregnant, we will ask you to have a pregnancy test before 
beginning this study.  You must use effective birth control methods and try not to become pregnant 
while participating in this study.  If you become pregnant, there may be unknown risks to your unborn 
child, or risks to your unborn child that we did not anticipate.  There may be long-term effects of the 
treatment being studied that could increase the risk of harm to an unborn child.  You must tell the doctor 
if your birth control method fails while you are on the study. If you believe or know you have become 
pregnant while participating in this research study, please contact the research team member identified at 
the top of this document as soon as possible.  Please discuss with the research team how long you need 
to wait before becoming pregnant after completing the treatment or procedures on this study. 
 
Risks for Sexually Active Males 
If you are a sexually active male, it is important that your partner not become pregnant during your 
participation in this study.  There may be unknown risks to the unborn child or risks we did not 
anticipate.  You and your partner must agree to use birth control if you want to take part in this study.  If 
you believe or know that your partner has become pregnant during your participation in this study, 
please contact the research team member identified at the top of this document as soon as possible. 
 
Risks of Genetic Research 
There is a federal law called the Genetic Information Nondiscrimination Act (GINA). In general, this 
law makes it illegal for health insurance companies, group health plans and employers with greater than 
15 employees to discriminate against you based on your genetic information. However, it does not 
protect you against discrimination by companies that sell life insurance, disability insurance or long 
term-care insurance.

for verifying and reporting results. We would be unable to provide you with any certainty that the results 
were accurate. As it would not be recommended that you rely on the results to take any action with 
regards to your healthcare we will not be returning this information to you. 
 
Risk of Breach of Confidentiality 
One risk of participating in this study is that confidential information about you may be accidentally 
disclosed.  We will use our best efforts to keep the information about you secure.  Please see the section 
in this consent form titled “How will you keep my information confidential?” for more information. 
 
WHAT ARE THE BENEFITS OF THIS STUDY? 
You may or may not benefit from being in this study.   
 
However, we hope that, in the future, other people might benefit from this study because it will help 
researchers learn more about how to treat AML with TP53 mutation. 
 
WHAT OTHER TREATMENT OPTIONS ARE THERE? 
Before you decide whether or not to be in this study, your doctor will discuss the other options that are 
available to you.  Instead of being in this study, you could: 
• Get treatment or care for your cancer without being in a study; 
• Take part in another research study; 
• Get no treatment; 
• Get comfort care, also called palliative care, which helps reduce pain, tiredness, appetite 
problems, and other problems caused by the cancer without treating the cancer directly. 
 
WILL IT COST ME ANYTHING TO BE IN THIS STUDY? 
As part of this study you will receive tests and procedures that are similar to what you would receive 
during routine clinical care of your condition.  Your health plan/insurance company will be billed for 
some or all of these costs, and you will be responsible for any co-pays and deductibles that are normally 
required by your health plan/insurance.  Not all insurance plans cover the costs associated with being in 
a study. Even if they do, you may be responsible for more out-of-pocket expenses, such as co-pays and 
deductibles, when there are more tests and procedures or more expensive tests and procedures involved 
in the study than if you were to receive routine clinical care outside the study.   
 
If you wish to know whether there are more tests and procedures or more expensive tests and procedures 
in the study, you should ask your study doctor.   
 
If you wish to know whether your insurance will pay, you should contact them directly, or speak with 
the study team about obtaining a financial pre-certification prior to enrolling in the study. 
 
WILL I BE PAID FOR PARTICIPATING? 
You will not be paid for being in this research study.   
 
WHO IS FUNDING THIS STUDY?

You have the right to share your information or involvement in this study with anyone at any time. You

Are there additional protections for my health information? 
Protected Health Information (PHI) is health information that identifies you. PHI is protected by federal 
law under HIPAA (the Health Insurance Portability and Accountability Act). To take part in this 
research, you must give the research team permission to use and disclose (share) your PHI for the study 
as explained in this consent form.  The research team will follow state and federal laws and may share 
your health information with the agencies and people listed under the previous section titled, “How will 
you keep my information confidential?” 
 
Once your health information is shared with someone outside of the research team, it may no longer be 
protected by HIPAA.   
 
The research team will only use and share your information as talked about in this form or as permitted 
or required by law.  When possible, the research team will make sure information cannot be linked to 
you (de-identified).  Once information is de-identified, it may be used and shared for other purposes not 
discussed in this consent form. If you have questions or concerns about your privacy and the use of your 
PHI, please contact the University’s Privacy Officer at 866-747-4975.  
 
Although you will not be allowed to see the study information, you may be given access to your health 
care records by contacting your health care provider.  
 
If you decide not to sign this form, it will not affect 
• your treatment or the care given by your health provider.

• any benefits to which you are entitled. 
However, it will not be possible for you to take part in the study.
