Overall Study Design: 
This is an open-label, dose-escalation/dose-expansion study of the lysine-specific demethylase 1 (LSD1) 
inhibitor INCB059872 as a monotherapy and combination therapy in subjects with advanced 
malignancies.  Subjects will receive INCB059872 doses once every other day (QOD) on a 28-day 
continuous therapy schedule; if QOD is well-tolerated, the next dose may be administered at a different 
dosing regimen (ie, once daily [QD]) but will not exceed the 100% dose escalation for a total daily dose.  
The study will be conducted in 4 parts:  Parts 1 and 2 will evaluate INCB059872 as monotherapy, with 
Part 1 for dose escalation and Part 2 for dose expansion, and Parts 3 and 4 will evaluate INCB059872 in 
combination with select therapies, with Part 3 for combination dose escalation and Part 4 for combination 
dose expansion.  Part 1 (monotherapy dose escalation) will determine the starting dose(s) of INCB059872

for dose expansion, based on maximum tolerated dose (MTD).  The recommended dose(s) will be taken 
forward into Part 2 (monotherapy dose expansion).  It is important to note that there may be a different 
MTD in different treatment groups.  The initiation of Part 2 will be based on further review of the 
ongoing clinical study and preclinical data of INCB059872 and information from literature.  Part 3 (dose 
escalation of INCB059872 in combination therapy) will be initiated after the MTD in Part 1 is 
determined.  Part 4 (dose expansion of INCB059872 in combination therapy) will explore the dose(s) 
confirmed in Part 3 and the dose(s) may be different based on combination therapy and/or tumor type. 
Monotherapy Dose Escalation (Part 1) 
Approximately 24 subjects will be enrolled into each dose-escalation treatment group. 
Treatment Group A will enroll subjects with AML or MDS.  The enrollment in TG B is prioritized for 
SCLC.  Enrollment of subjects with other solid malignancies (eg, endocrine tumors) is allowed with the 
sponsor medical monitor approval. 
Dose escalation for TG A and TG B in Part 1 will proceed independently, with each treatment group 
following a 3 + 3 design.  The starting dose of INCB059872 for TG A and TG B will be 2 mg QOD.  A 
minimum of 3 subjects will initially be enrolled in each treatment group in Part 1, and each subject will be 
observed for a dose-limiting toxicity (DLT) observation period of 1 cycle (28 days) before the next dose 
cohort begins enrollment.  Subjects must have taken at least 75% of the cohort-specific dose (at least 
11 doses for QOD schedule or at least 21 doses for QD schedule) in the first 28 days of study treatment or 
have had a DLT to be considered evaluable.  Subjects who are not evaluable will be replaced.  The dose 
will be escalated by up to 100% if none (0) of the first 3 evaluable subjects enrolled has a DLT.  Dose 
escalation should proceed in smaller increments (ie, by no more than 50%) if a DLT is observed, or if 2 or 
more subjects at a given dose level experience Grade 2 or higher AEs (unless they are clearly and 
incontrovertibly due to an alternative cause).   
If 1 of the first 3 evaluable subjects enrolled has a DLT, the cohort will be expanded to include 
3 additional evaluable subjects, and if no DLT occurs in the additional 3 subjects, then the dose will be 
escalated by up to 100%.  Otherwise, if 2 subjects in a cohort of 3 or 6 subjects experience DLTs, the 
MTD will be deemed to be exceeded.  An interim lower dose level may be explored if the dose increment 
has been 100%.  The MTD will be defined as one dose level below the dose level at which one-third or 
more subjects experience DLTs.  Upon the aggregate review of overall safety, PK, 
and efficacy, a 
recommended dose (per tumor type) will be determined to maximize the clinical benefit/risk margin. 
Monotherapy Dose Expansion (Part 2) 
Upon identification of the recommended dose(s), up to 4 expansion cohorts per tumor type of 
approximately 15 subjects each may begin enrollment to further determine safety, tolerability, efficacy, 
PK, 
 of the selected dose(s).  Treatment Group A1 will enroll subjects with AML or MDS and 
subjects in this cohort will have an opportunity to switch their treatment to a combination dose that is 
tested and found safe.  Only subjects who have stable disease or better response for ≥ 3 months on 
monotherapy will be allowed to do so.  Treatment Group A2 will enroll subjects with primary 
myelofibrosis (PMF) or secondary MF (post–polycythemia vera myelofibrosis [PPV-MF] or post–
essential thrombocythemia myelofibrosis [PET-MF]).  Treatment Group B1 will enroll subjects with 
SCLC.  Treatment Group B2 will enroll subjects with Ewing's sarcoma and poorly differentiated 
neuroendocrine tumors.  The selected doses for each treatment group are as follows: 
• 
TG A1 dose will be 4 mg QD based on the safety and tolerability assessment in TG A. 
• 
TG A2, TG B1, and TG B2 doses will be 3 mg QOD based on the safety and tolerability assessment 
in TG B (Part 1). 
A study of the effect of food on the PK of INCB059872 will be conducted in Part 2, TG B1 only. 
Note:  Based on emerging data, the sponsor may decide to enroll specific subtypes of AML in TG A1.   
 
If ≥ 5 subjects in the first 15 subjects of any cohort cumulatively (or more than 33% of subjects in cohorts

larger than 15 subjects) experience DLTs during Cycle 1, then further enrollment to the cohort will be 
stopped, and a lower dose level may be explored. 
Individual dose titration will be permitted according to Protocol-defined safety parameters.  Subjects will 
continue to receive INCB059872 in 28-day cycles until a withdrawal criterion is met.   
Combination Dose-Finding (Part 3) 
Part 3 enrollment will be initiated after the MTD has been determined in Part 1 and will include 
dose-finding to evaluate safety and tolerability of the combinations.  Enrollment of Part 3 will occur in 
parallel with Part 2.  Dose-finding will use a 3 + 3 design to evaluate different doses of INCB059872 in 
combination with other therapies in the following treatment groups:  
• 
Combination TG C:  INCB059872 in combination with all-trans retinoic acid (ATRA) in subjects 
with relapsed/refractory AML.  The starting dose for INCB059872 in this cohort will be 2 mg QD 
(2 dose levels below the recommended dose for monotherapy expansion in TG A1). 
• 
Combination TG D:  INCB059872 in combination with azacitidine in subjects with newly diagnosed, 
treatment-naive AML or MDS with at least 5% bone marrow blasts and IPSS-R intermediate or 
higher risk disease who are unfit to tolerate standard intensive chemotherapy at study entry and who 
are eligible to receive azacitidine as first-line therapy for the disease under study.  The starting dose 
for INCB059872 in this cohort will be 2 mg QD (2 dose levels below the recommended dose for 
monotherapy expansion in TG A1). 
• 
Combination TG E:  INCB059872 in combination with nivolumab in subjects with advanced SCLC 
previously progressed on platinum-based treatment.  The starting dose for INCB059872 in this cohort 
will be 3 mg QOD (the recommended dose for monotherapy expansion in TG B1). 
The starting dose of INCB059872 in the combination treatment groups will be based upon the tolerability 
of INCB059872 monotherapy identified in Part 1 of this study.  Doses of the combination agents will be 
selected from conventional dose regimens and will remain the same for all dose-finding and 
dose-expansion cohorts.  INCB059872 doses will not exceed the monotherapy MTD identified in Part 1.  
A minimum of 3 subjects will initially be enrolled in each treatment group in Part 3, and each subject will 
be observed for a DLT observation period of 1 cycle (28 days) before the next dose cohort or expansion 
to Part 4 begins enrollment.  Subjects must have taken at least 75% of the cohort-specific dose (at least 
11 doses for QOD schedule or at least 21 doses for QD schedule) in the first 28 days of study treatment or 
have had a DLT to be considered evaluable.  Subjects who are not evaluable will be replaced. 
If tolerated, the combination treatment groups will escalate independently and in parallel until the MTD 
or optimal doses of the combinations are identified and will be followed by independent expansion 
cohorts at the selected dose(s).  If the starting dose is not tolerated in any of the combination treatment 
groups, a lower dose of INCB059872 may be explored; otherwise, higher doses found to be safe and 
tolerable in Part 1 may be explored.  The sponsor, in consultation with participating investigators, may 
elect to expand a dose cohort(s) deemed tolerable, to up to 12 subjects, in order to obtain supplemental 
PK, 
, and safety data. 
Combination Dose Expansion (Part 4) 
Upon identification of the recommended dose(s) for each treatment combination in Part 3, expansion 
cohorts of approximately 30 subjects in each treatment group may begin enrollment to further determine 
safety, tolerability, efficacy, PK, 
 of the selected dose(s). 
• 
Combination TG C1:  INCB059872 in combination with ATRA using the regimen identified in Part 3 
in subjects with relapsed/refractory AML. 
• 
Combination TG D1:  INCB059872 in combination with azacitidine using the regimen identified in 
Part 3 in subjects with newly diagnosed, treatment-naive AML or MDS with at least 5% bone marrow 
blasts and IPSS-R intermediate or higher risk who are unfit to tolerate standard intensive 
chemotherapy at study entry and who are eligible to receive azacitidine as first-line therapy for the 
disease under study.

Part 3 in subjects with advanced SCLC who previously progressed on platinum based treatment. 
In Part 4, a stopping rule for futility is planned for each combination dose expansion treatment group.  
The futility analyses for combination TGs will be conducted when 15 subjects for each disease type have 
been treated and evaluated for response or have permanently discontinued study treatment because of 
disease progression, withdrawal of consent, or death.  The futility analyses for TG D1 will be conducted 
when the first 15 subjects with AML or when the first 15 subjects with MDS have been treated.

INCB059872/Study Drug, Dosage, and Mode of Administration: 
INCB059872 will be self-administered orally QOD or QD on a 28-day cycle.  In each cycle of the QOD 
dosing schedule, subjects should receive 14 doses of INCB059872.  In each cycle of the QD dosing 
schedule, subjects should receive 28 doses of INCB059872.  Tablets will be available in 1 mg strength.  
The initial starting dose for Part 1 will be 2 mg QOD.  The initial starting dose for other parts of the study 
will be based on the aggregate data review of Part 1. 
For QOD administration, if a dose is missed by more than 24 hours, the subject should skip the dose and 
take the next scheduled dose at the usual time.  For QD administration, if a dose is missed by more than 
4 hours, the subject should skip the dose and take the next scheduled dose at the usual time.  INCB059872 
tablet should be taken on an empty stomach if possible (refrain from food consumption during the period 
2 hours before and 1 hour after taking INCB059872).  For subjects participating in the food-effect portion 
of the study in Part 2, TG B1, a high-fat, high-calorie meal will be consumed within 30 minutes before 
taking INCB059872 on Cycle 2 Day 1. 
Alternative dosing regimens (ie, once daily) may be explored based on emerging PK/
 and safety 
data. 
Reference Therapy, Dosage, and Mode of Administration:   
Conventional regimens of the standard of care combination agents or nivolumab will be used throughout 
Parts 3 and 4 of the study.  Tretinoin capsules (ATRA) will be administered as an open-label commercial 
product at a starting dose of 45 mg/m2 per day as 2 evenly divided doses.  
Azacitidine will be administered as an open-label commercial product at a starting dose of 75 mg/m2 
subcutaneously or intravenously for 7 days during the first 9-day or less period (ie, a 2-day break allowed 
on weekend, if needed) of each 28-day treatment cycle.  
Nivolumab will be administered at a dose of 3 mg/kg as an intravenous infusion over 60 minutes every 
2 weeks.  
Premedications should be administered per standard-of-care guidelines. 
Study Schedule/Procedures: 
Subjects will have regularly scheduled study visits at the clinical site as part of a 28-day cycle.  Study 
visits are as follows: 
• 
Screening:  Day -28 through Day -1 
• 
Cycle 1:  Day 1, 4, 8, 11, 15, 22 
• 
Subsequent cycles:  Day 1 (± 2 days; note that Day 1 must be a day with INCB059872 treatment) and 
Day 15 (± 2 days) 
• 
End of treatment:  Subjects must be seen and have blood drawn 2 times per week for 2 weeks after 
last dose.  
• 
Safety follow-up:  30 days (+ 5 days) after the EOT visit or last dose of study drug if EOT visit not 
performed (or until toxicities resolve, return to baseline, are deemed irreversible, or the subject 
receives another anticancer therapy, whichever is shorter).

Combination TG E1 will be terminated for futility if ≤ 1 of the 15 subjects responded (ie, CR or PR) 
based on assessments provided by investigator. 
Data Monitoring Committee:   
No independent Data Monitoring Committee is planned for this study.  Decisions to continue the 
enrollment in subsequent dose level cohort, dose level to be tested, as well as number of subjects to be 
evaluated, will be made after the appropriate data are collected and reviewed by sponsor representatives 
(eg, medical monitor) and investigators or designees.  The group of sponsor representatives and 
investigators or designees will convene regularly (eg, once weekly) or ad hoc for specific discussions.  
Meeting minutes will be documented. 
An internal Data Safety Monitoring Board (iDSMB) will review safety data at regular intervals 
throughout the study.  The frequency of meetings will be contingent upon enrollment and availability of 
safety data for analysis and review.  Details regarding membership, roles, and responsibilities of the 
committee are specified in the iDSMB charter.

INTRODUCTION 
1.1. 
Background 
INCB059872 is a covalent flavin adenine dinucleotide (FAD)-directed inhibitor of 
lysine-specific demethylase 1 (LSD1) that is proposed for the treatment of advance 
malignancies.  LSD1 regulates gene expression epigenetically by removing methylation marks 
from lysine 4 or 9 of histone H3.  Target genes of LSD1 are involved in may biological 
processes, including cell growth, survival, differentiation, and stem cell homeostasis.  Studies 
have shown that deregulated LSD1 activity is associated with human diseases, including cancer, 
where overexpression of LSD1 is frequently associated with poor clinical outcomes.  Refer to the 
Investigator's Brochure (IB) for additional background information on INCB059872. 
1.1.1. 
Lysine Demethylase 1 Inhibitor in Oncology 
Epigenetic modifications significantly contribute to the development of various cancers 
(Dawson and Kouzarides 2012).  Analyses of cancer genomes have revealed that multiple 
epigenetic regulatory genes are often overexpressed or mutated in a variety of cancers 
(Shen and Laird 2013).  One particular epigenetic enzyme that is associated with human cancer 
is LSD1, the first discovered histone demethylase and a key epigenetic regulator of chromatin 
architecture (Shi et al 2004).  Methylated histone marks on H3K4 and H3K9 are coupled with 
transcriptional activation and repression, respectively.  As part of the corepressor complex (eg, as 
corepressor of RE1 silencing transcription factor) (Stavropoulos et al 2006), LSD1 has been 
reported to demethylate H3K4 and represses transcription, whereas LSD1 in the nuclear 
hormone receptor complex (eg, androgen receptor) may demethylate H3K9 to activate gene 
expression (Metzger et al 2005).  This suggests that the substrate specificity of LSD1 can be 
determined by associated factors, thereby regulating alternative gene expression in a 
context-dependent manner.  In addition to histone proteins, LSD1 demethylates several 
nonhistone proteins critical in the regulation of cell growth, differentiation, and survival 
pathways.  These include p53 (Huang et al 2007), E2F (Kontaki and Talianidis 2010), STAT3 
(Yang et al 2010), Tat (Sakane et al 2011), and myosin phosphatase target subunit 1 
(Cho et al 2011).  These findings suggest the potential for additional oncogenic roles of LSD1 
beyond its epigenetic role in regulating chromatin remodeling.  LSD1 also associates with other 
epigenetic regulators, such as DNA methyltransferase 1 (DNMT1) (Wang et al 2009) and histone 
deacetylase (HDAC) (You et al 2001).  These associations augment the activities of DNMT or 
HDACs.  LSD1 inhibitors may therefore potentiate the effects of HDAC or DNMT inhibitors 
(Han et al 2013, Singh et al 2011). 
LSD1 contributes to a variety of biological processes, including the regulation of cell 
proliferation, the epithelial-mesenchymal transition, cellular transformation of somatic cells, and 
self-renewal and differentiation, the latter impacting stem cell biology both in embryonic stem 
cells and in cancer stem cells (Chen et al 2012, Adamo et al 2011).  These cancer stem cells may 
render cancer cells resistant to conventional therapies, such as chemotherapy or radiotherapy, 
and promote tumor recurrence after treatment (Beck and Blanpain 2013).  In this regard, LSD1 
functions in maintaining an undifferentiated tumor initiating or cancer stem cell phenotype in a 
spectrum of cancers (Wang et al 2011, Zhang et al 2013).  Notably, acute myeloid

CONFIDENTIAL 
leukemia (AML) cells retain a less differentiated stem cell−like phenotype or leukemia stem 
cell (LSC) potential.  Genome-wide gene expression analyses have revealed that LSD1 regulates 
a subset of genes involved in multiple oncogenic programs to maintain the LSC phenotype in 
AML, and inhibition of LSD1 has demonstrated therapeutic benefit in preclinical models of 
murine and human AML (Harris et al 2012, Schenk et al 2012).  A variety of additional 
hematologic cancers also overexpress LSD1, including significant subsets of high-grade B-cell 
and T-cell non-Hodgkin's lymphomas and Hodgkin's lymphomas (Niebel et al 2014), although 
the therapeutic benefit of LSD1 inhibition in these cancers has not yet been evaluated.  
In addition to hematologic malignancies, overexpression of LSD1 is frequently observed in 
many types of solid tumors, and its expression is associated with a more clinically aggressive 
phenotype and poor prognostic outcome.  Cancers in which overexpression of LSD1 has been 
documented include  bladder cancer (Hayami et al 2011), small cell lung cancer (SCLC) 
(Mohammad et al 2015), non-SCLC (Lv et al 2012), breast cancer (Lim et al 2010), ovarian 
cancer (Konovalov and Garcia-Bassets 2013), glioma (Sareddy et al 2013), colorectal cancer 
(Hayami et al 2011, Ding et al 2013), a variety of sarcomas (Bennani-Baiti et al 2012),  
neuroblastoma (Schulte et al 2009), prostate cancer (Suikki et al 2010), esophageal squamous 
cell cancer (Yu et al 2013), papillary thyroid cancer (Kong et al 2013), and Ewing sarcoma 
(Sankar et al 2014).  In these studies, either genetic knockdown of LSD1 expression or treatment 
with small-molecule inhibitors of LSD1 resulted in decreased cancer cell proliferation and/or 
induction of apoptosis both in vitro and in vivo.  These findings suggest a potential therapeutic 
benefit of LSD1 inhibitors in a broad range of cancers beyond AML.

modify the cofactor FAD to inhibit the enzymatic activity of LSD1 (Ueda et al 2009, 
Suzuki and Miyata 2011).  INCB059872 potently inhibited the enzymatic activity of LSD1, with 
an average half maximal inhibition (IC50) value of 18 ± 3 nM.  INCB059872 was highly specific 
for LSD1, as it did not inhibit LSD2 at 5 μM, nor monoamine oxidase-A (MAO-A) and MOA-B 
at concentrations as high as 20 μM. 
1.2.1. 
Pharmacology of INCB059872 
In enzyme-based assays, INCB059872 potently inhibited LSD1, with IC50 values of 18 ± 3 
(average ± SD), while INCB059872 did not inhibit LSD2 and MAO-A/B.  Both biochemical and 
in vitro pharmacodynamic (PD) assays consistently demonstrated that INCB059872 was a 
FAD-directed inhibitor of LSD1.  In cellular assays, INCB059872 inhibition resulted in the 
upregulated expression of the differentiation markers, CD86 and CD11b, in multiple AML cell 
lines and human primary AML cells across the different French-American-British (FAB) 
subtypes.  Using the human acute monocytic leukemia cell line, THP-1, spiked into human 
whole blood to estimate potency in the presence of human serum proteins, INCB059872 induced 
CD86 protein, with a half maximal effective concentration (EC50) value of 23 ± 8 nM.  Human 
AML cell lines showed various degrees of sensitivity to INCB059872 in cell proliferation assays, 
with EC50 values ranging from 17 to 314 nM, and treated cells underwent G1 cell cycle arrest.  
The antitumor activity of INCB059872 was further evaluated in human primary AML cells 
ex vivo.

The proliferation of a number of SCLC cell lines was also inhibited by INCB059872, with IC50 
values ranging from 47 to 377 nM.  Nontumorigenic cells, by contrast, were significantly less 
sensitive to INCB059872, with IC50 values > 10 μM in interleukin-2–stimulated T cells from 
normal donors.  INCB059872 also demonstrated no significant effects on cellular proliferation or 
survival in HEK293 human embryonic kidney cells at concentrations up to 20 μM.  These data 
demonstrate that INCB059872 inhibits LSD1 activity in vitro, and that inhibition of LSD1 results 
in the growth arrest and differentiation of cancer cells compared to normal cells.  In vitro PD 
assays for LSD1 inhibition in AML cells showed that induction of the CD86 myeloid 
differentiation marker by INCB059872 was sustained for 5 days after removal of INCB059872 
in culture.  These results confirm that INCB059872 is a covalent FAD-directed inhibitor in cells. 
In vivo, oral administration of INCB059872 demonstrated PD activity and efficacy in several 
models of human and murine AML and in human SCLC xenograft models in mice.  Tumor PD 
analyses conducted in both the Molm-13 human AML systemic xenograft model and the THP-1 
human AML subcutaneous (SC) xenograft model demonstrated induction of CD86 and CD11b 
expression, consistent with in vitro data.  In these models, the PD activity of INCB059872 was 
marginal at a dose of 0.1 mg/kg and maximal at doses ≥ 0.5 mg/kg, demonstrating an in vivo 
median effective dose (ED50) for CD86 induction of approximately 0.3 mg/kg.  In addition, 
tumor PD responses were sustained for over 48 to 72 hours after dosing, suggesting a possible 
irreversible inhibition of LSD1 by covalent modification of FAD.  Consistent with in vivo PD 
studies, once daily (QD) doses of INCB059872 greater than the in vivo ED50 showed significant 
and comparable antitumor effects in human AML cell line xenograft models, while doses less 
than the in vivo ED50 exhibited either no efficacy or marginal tumor growth inhibition in these 
tumor xenograft models.  Similar effects of QD dosing regimens on tumor growth inhibition 
were observed in human SCLC tumor xenograft models (NCI-H562 and NCI-H1417), with a 
marked reduction in plasma pro−gastrin-releasing peptide (Pro-GRP) levels in 
INCB059872-treated NCI-H1417 tumor-bearing mice relative to vehicle controls.  Alternative 
oral dosing regimens of INCB059872, including every other day (QOD), generally were 
comparably efficacious as a QD dosing regimen in these AML and SCLC xenograft models, 
consistent with the prolonged PD effects associated with INCB059872. 
In the MLL-AF9 murine leukemia engraftment model in C57BL/6mice, the median survival of 
leukemic animals was significantly prolonged in mice receiving doses greater than or equal to a 
pharmacodynamically active oral dose of INCB059872 over a 14-day dosing period.  These 
survival effects of INCB059872 in the MLL-AF9 murine AML model were associated with an 
expansion of the percentage of normal bone marrow cells, a reduction in LSCs, a decrease in the 
number of AML blast cells, the induction of myeloid differentiation, and a normalization of 
hematologic parameters to those of nonleukemic mice. 
INCB059872 was evaluated against a panel of targets to assess the potential for unintended 
pharmacological activity.  There was no significant cross-reactivity against any of the 55 in vitro 
binding assays in which INCB059872 was tested.  INCB059872 was evaluated in kinase 
profiling assays at concentrations up to 20 μM, and no inhibitory activity for any of the 
56 kinases tested was noted.  INCB059872 was evaluated against a panel of selected ion cardiac 
channels (L-type calcium, human ether-à-go-go-related gene [hERG] potassium, hKir2.1 
potassium, hKvLQT1/hminK potassium, hKv4.3 potassium, hNav1.5 sodium) in an automatic 
parallel patch clamp system; none of these channels was inhibited by more than 25% at 30 μM.

INCB059872 was also evaluated in the Good Laboratory Practice (GLP) in vitro hERG channel 
assay.  The IC50 for hERG inhibition was 149.3 μM, which is > 4000-fold higher than the 
anticipated steady-state free Cmax in humans.  Collectively, these in vitro and functional results 
support the conclusion that the risk of unintended pharmacological activity is expected to be low. 
1.2.2. 
Nonclinical Drug Metabolism and Pharmacokinetics of INCB059872 
The absorption, distribution, metabolism, and excretion of INCB059872, a covalent 
FAD-directed inhibitor for LSD1, have been characterized in rats, dogs, and monkeys.  
Following intravenous (IV) administration, the systemic clearance was low in monkeys and dogs 
(23% and 29% of hepatic blood flow, respectively) and moderate in rats (37% of hepatic blood 
flow).  The clearance mechanisms of INCB059872 include both cytochrome P450 
(CYP)-dependent metabolism and non−enzyme-dependent catabolism.  The administered dose 
excreted in urine as intact INCB059872 varied from approximately 9.9% in rats to 7.8% in dogs 
and 3.5% in monkeys, indicating renal clearance as minor elimination pathways.  INCB059872 
exhibited a moderate steady-state volume of distribution in all 3 species (0.9-1.5 L/kg), 
suggesting moderate distribution.  After oral administration, oral bioavailability was moderate in 
monkeys (37%) but high in rats (70%) and dogs (100%).  The terminal elimination half-life was 
1.0 hour in rats, 1.2 hours in dogs, and 3.3 hours in monkeys.  Despite a short half-life, sustained 
pharmacological activity was observed in vitro and in vivo, presumably a result of irreversible or 
covalent inhibition of LSD1, ie, a pharmacokinetic (PK)-PD divergence is expected for this 
mode of inhibition by INCB059872.  Based on allometric scaling, the terminal elimination 
half-life in human is projected to be approximately 3 hours, and the oral bioavailability is 
projected to be 70%.  Significant antitumor effects were observed in mice when peak plasma 
concentration exceeded the EC50 in the whole blood assay with either QD or QOD dosing.  
Based on preclinical PK-PD relationship assessment, the projected clinical dose for efficacy in 
patients is 2 mg QOD, which is expected to provide plasma concentrations exceeding the EC50 of 
0.023 μM (based on THP-1 spiked whole blood assay with CD86 induction) for 2 hours, the total 
steady-state plasma AUC0-48 and Cmax is estimated to be approximately 0.2 μM∙h and 0.05 μM, 
respectively. 
INCB059872 exhibits moderate in vitro permeability across Caco-2 monolayers 
(3.8 × 10-6 cm/sec) and high aqueous solubility (20 mg/mL).  In vitro transport studies indicate 
that INCB059872 is a weak substrate of efflux transporter P-glycoprotein, but not of breast 
cancer resistance protein.  INCB059872 has limited penetration across the rat blood-brain 
barrier, with a steady-state brain-to-plasma ratio of 0.1.  In vitro human protein binding of 
INCB059872 was low (unbound fraction of 73.5%), similar to that in preclinical species. 
INCB059872 did not inhibit hepatic uptake transporters (OATP1B1 and OATP1B3).  While 
INCB059872 was a weak inhibitor of renal uptake transporters (OCT2, OAT1, and OAT3), no 
drug-drug interactions are expected based on the projected steady-state human plasma Cmax 
value.  Moreover, INCB059872 did not inhibit P-glycoprotein or breast cancer resistance protein 
efflux transporters.  Reaction phenotyping using recombinant human CYPs indicated that 
INCB059872 was metabolized by CYP2D6 and CYP3A4, and therefore it is possible that the PK 
of INCB059872 will be affected by coadministration of potent CYP2D6 inhibitors or CYP3A4 
inhibitors/inducers.  INCB059872 is not an inhibitor of the 6 CYPs evaluated, and therefore no 
drug-drug interaction is expected based on INCB059872 CYP inhibitory activities at 
pharmacologically relevant exposures of INCB059872.  The metabolism profile of INCB059872

in rat, dog, monkey, and human in vitro liver preparations was qualitatively similar, with M1 
(INCB061984) generated at levels > 10% of INCB059872 across all species.  However, M1 was 
also generated in buffer or buffer fortified with rat bile, bilirubin, and FAD, indicating that 
nonenzymatic mechanisms are also involved in the formation of M1.  There was no evidence of 
any human-specific metabolites.  In vivo, parent INCB059872 was the most abundant component 
in rat and dog plasma, and M1 (INCB061984) was identified in rat plasma (approximately 4% of 
INCB059872) and dog plasma (approximately 40% of INCB059872). 
1.3. 
Overview of Conventional Care Agents 
1.3.1. 
All-Trans Retinoic Acid 
All-trans retinoic acid (ATRA) is the acid form of vitamin A.  It induces cell differentiation and 
decreases proliferation of acute promyelocytic leukemia (APL) cells by interrupting oncogenic 
transcriptional activities of retinoic acid receptor-alpha.  It is currently indicated for use in 
patients with acute APL (Vesanoid PI 2010).  Monotherapy of ATRA is associated with high 
complete remission rate, ranging from 70% to 85% (Huang et al 1988, Tallman et al 1997, 
Tallman et al 2002). 
The intended use of ATRA in the proposed study is to assess safety and preliminary clinical 
benefit of the combination therapy with INCB059872.  ATRA-based therapies have shown 
utility in clinical studies (Hoffman et al 2012).  However, ATRA-based therapies have not been 
effective in non-APL AML, but the combination of ATRA and tranylcypromine (a nonspecific 
LSD1 inhibitor) unlocked the ATRA-driven therapeutic response and diminished the 
engraftment of primary human non-APL AML (Schenk et al 2012).  Synergistic inhibition of 
leukemia cell viability was observed when ATRA was combined with INCB059872 in 
preclinical study.  ATRA in combination with other agents, particularly those targeting 
epigenetics, has been shown to be potentially beneficial in myelodysplastic syndrome (MDS; 
Kuendgen et al 2005).  ATRA metabolism is not affected by P450 enzyme, and its metabolic 
drug-drug interaction with INCB059872 is not anticipated. 
1.3.2. 
Azacitidine 
Azacitidine is a nucleoside metabolic inhibitor that is approved by the FDA and EMA for the 
treatment of patients with several different subtypes of MDS (Vidaza PI 2014).  Azacitidine is 
thought to have 2 main mechanisms of antineoplastic action:  cytotoxicity, resulting from 
incorporation into RNA and DNA, and DNA hypomethylation, restoring normal growth control 
and differentiation in hematopoietic cells (Kaminskas et al 2005).  Several clinical studies have 
demonstrated the efficacy of azacitidine in MDS.  In a Phase 2 clinical study evaluating 
azacitidine versus supportive care in high-risk MDS, Silverman et al (2002) reported a 60% 
overall response rate (including hematologic improvement) for azacitidine as compared with 5% 
receiving supportive care.  Additionally, a Phase 3 study (Al-Ali et al 2012, Fenaux et al 2009) 
evaluating azacitidine versus conventional care in higher risk MDS revealed superior rates of 
hematologic response (29% vs 12%) and hematologic improvement (49% vs 29%) in the 
azacitidine group.

Azacitidine is recommended as a low-intensity induction therapy in AML, primarily in patients 
who are unfit for high- or intermediate-intensity regimens, especially in patients ≥ 60 years 
(NCCN 2017).  In the AZA-AML-001 study (Dombret et al 2015), azacitidine (n = 241) was 
compared with conventional therapies (best supportive care, low-dose cytarabine [L-DAC], and 
standard induction therapy; n = 247) in patients age ≥ 65 years with newly diagnosed AML with 
> 30% bone marrow blasts.  Median OS was improved (10.4 months vs 6.5 months, hazard ratio 
[HR] = 0.85, p = 0.10009) but did not reach statistical significance; mOS did reach statistical 
significance (12.1 months vs 6.9 months, HR = 0.76, p = 0.019) when the patients were censored 
at the start of subsequent AML therapy by prespecified sensitivity analysis.  Also, patients with 
poor-risk cytogenetics (HR = 0.68) and with myelodysplasia-related changes (HR = 0.69) 
benefited significantly from azacitidine.  Even though the study was not powered to compare 
azacitidine with individual conventional therapy, the OS of patients treated with azacitidine or 
L-DAC (n = 154 vs 158) did not differ significantly, and comparable survival rates were also 
observed comparing azacitidine with standard induction therapy (n = 43 vs 44), and azacitidine is 
superior to best supportive care by post hoc analysis.  Azacitidine achieved a complete response 
(CR) of 19.5% versus 21.9% with conventional therapies, CR/complete remission with 
incomplete hematologic recovery (CRi) 27.8% versus 25.1%.  The most common 
treatment-emergent adverse events (TEAEs) ≥ G3 occurring in ≥ 20% of patients in the 
azacitidine arm were febrile neutropenia, neutropenia, thrombocytopenia, pneumonia, and 
anemia.  Although there has been limited investigation into the use of azacitidine in 
relapsed/refractory AML, Al-Ali et al (2012) reported a 10% overall response rate (including 
hematologic improvement) in subjects who were resistant to primary chemotherapy.  Azacitidine 
undergoes spontaneous hydrolysis and deamination mediated by cytidine deaminase.  
Cytochrome P450 enzyme induction or inhibition by azacitidine at clinically achievable plasma 
concentrations is unlikely, and metabolic drug-drug interaction between INCB059872 and 
azacitidine is not anticipated. 
1.3.3. 
Overview of Nivolumab 
Nivolumab is a fully human immunoglobulin G4 monoclonal antibody that selectively inhibits 
programmed cell death-1 (PD-1) activity by binding to the PD-1 receptor to block the ligands 
programmed death ligand 1 (PD-L1) and PD-L2 from binding.  The negative PD-1 receptor 
signaling that regulates T-cell activation and proliferation is therefore disrupted 
(Robert et al 2015).  This releases PD-1 pathway-mediated inhibition of the immune response, 
including the antitumor immune response.  Nivolumab has demonstrated activity in early phase 
clinical studies, and Phase 3 studies (including CheckMate 331) are ongoing to evaluate the role 
of nivolumab in the management of relapsed SCLC.  In the Phase 1/2 study CheckMate 032 
(NCT01928394), multiple regimens of nivolumab were evaluated with (n = 61) or without 
(n = 98) ipilimumab in solid tumors, including SCLC.  Durable responses were observed in both 
the nivolumab and the nivolumab + ipilimumab treatment arms in subjects with previously 
treated SCLC regardless of PD-L1 expression (Hellman et al 2017). 
Nivolumab has been approved as monotherapy in the United States for the treatment of patients 
with unresectable or metastatic melanoma, metastatic non–small cell lung cancer (NSCLC), 
advanced renal cell carcinoma (RCC), recurrent or metastatic squamous cell carcinoma of the 
head and neck, and classical Hodgkin lymphoma.  Nivolumab is also approved in combination 
with ipilimumab in patients with unresectable or metastatic melanoma (Opdivo PI 2017).

Nivolumab is approved in the European Union as monotherapy or in combination with 
ipilimumab for advanced (unresectable or metastatic) melanoma, as monotherapy for locally 
advanced or metastatic NSCLC after prior chemotherapy, for advanced RCC after prior therapy, 
and for Hodgkin lymphoma following autologous stem cell transplant and treatment with 
brentuximab vedotin (Opdivo SPC 2015). 
1.4. 
Study Rationale 
Cancer has several common characteristic that can be observed across numerous tumor types.  
One common characteristic is the uncontrolled growth and survival of cells and their ability to 
become invasive throughout the body.  LSD1 contributes to tumor development by altering 
epigenetic marks on histones and nonhistone proteins.  Accumulating data have validated that 
either genetic depletion or pharmacological inhibition of LSD1 normalizes oncogenic and cancer 
stem cell−like patterns of gene expression, thereby inducing differentiation programs, decreasing 
cell proliferation, and promoting apoptosis in cancer cells (Harris et al 2012, Schenk et al 2012).  
Therefore, LSD1 inhibitors have the potential to be effective treatments for human cancers with 
aberrant LSD1 activation. 
1.5. 
Justification of Route, Dose Regimen, and Treatment Period 
The starting dose of 2 mg INCB059872 administered QOD orally is proposed for this clinical 
study based on the assessment in GLP toxicology studies. 
INCB059872 will be administered orally QOD or QD over a 28-day cycle.  Part 1 will be a 
dose-escalating design in order to determine the recommended dose(s) of INCB059872 for 
dose-expansion (Part 2). 
The proposed starting dose and schedule of INCB059872 for combination therapy is based on 
preclinical data and emerging clinical data from Part 1 of this study.  To ensure safety of 
INCB059872 in combination with ATRA or azacitidine, the starting dose will be defined as 
2 dose levels below the RP2D from Part 1 (monotherapy dose escalation).  In Part 3, Treatment 
Group (TG) C, INCB059872 will be combined with ATRA (tretinoin) based on recent evidence 
to support synergism between ATRA and LSD1 inhibitors in AML (Schenk et al 2012).  
INCB059872 will be administered at a starting dose of 2 mg QD (2 dose levels below the RP2D) 
in combination with ATRA administered to subjects according to the commercial label 
(Vesanoid 2010), a starting dose of 45 mg/m2 per day administered as 2 evenly divided doses.  
Treatment Group D will combine INCB059872 at a starting dose of 2 mg QD with azacitidine.  
The azacitidine regimen selected for use in this study (dose of 75 mg/m2 SC or IV for 7 days 
during the first 9-day or less period [ie, a 2-day break allowed on weekend, if needed] of each 
28-day treatment cycle) is appropriate to the patient population.  The tolerability and activity of 
this regimen have been established (Lyons et al 2009, García-Delgado et al 2014) as an 
acceptable alternative to the recommended dosing schedule of Days 1 to 7 of each 28-day 
treatment cycle.  If tolerated, TG C and TG D will escalate independently and in parallel until the 
maximum tolerated dose (MTD) or optimal dose(s) of the combination is identified.  If the 
starting dose is not tolerated in any of the combination treatment groups, a lower dose of 
INCB059872 may be explored; otherwise, higher doses found to be safe and tolerable in Part 1 
may be explored.

Treatment Group E will combine INCB059872 at the RP2D for solid tumors, 3 mg QOD, in 
combination with nivolumab administered at a dose of 3 mg/kg administered as an IV infusion 
over 60 minutes every 2 weeks.  If the starting dose is not tolerated in any of the combination 
treatment groups, a lower dose of INCB059872 may be explored.  
1.6. 
Potential Risks and Benefits of the Treatment Regimen 
1.6.1. 
Potential Risks of INCB059872 Based on Preclinical Safety 
The nonclinical safety program to support this IND was designed in accordance with ICH S9 for 
advanced cancer.  In pivotal 1-month studies, INCB059872 was administered on a QOD 
regimen.  The doses and dosing regimen for the pivotal GLP studies were selected based on the 
results of previous range-finding studies, where findings in the bone marrow (most prominent: 
abnormal megakaryocytes, decreased megakaryocytes) leading to marked thrombocytopenia 
resulted in subsequent internal and external hemorrhages in rats given ≥ 3 mg/kg (human 
equivalent dose 28.8 mg) QD and in dogs given ≥ 1 mg/kg (human equivalent dose 32.4 mg) 
QD.  These observations suggested that QOD dosing may provide the best option for 
maximizing efficacy (which was similar after QD and QOD dosing regimens in nonclinical 
pharmacology studies) while minimizing toxicity (thrombocytopenia). 
The primary INCB059872 toxicity findings included abnormal megakaryocyte morphology in 
bone marrow, thrombocytopenia, lower red blood parameters and higher reticulocytes, decreased 
mature granulocytes in the bone marrow and neutropenia, and increased monocyte count, and 
were attributed to the pharmacological activity of INCB059872.  These findings were all 
partially or fully reversible after a 4-week recovery period.  The toxicities produced by 
INCB059872 are similar to those described for a conditional LSD1 knockdown model in mice as 
described in literature (Sprüssel et al 2012), where LSD1 deficiency suppressed terminal 
granulopoiesis, erythropoiesis, and platelet production, with the exception of monopoiesis, which 
was promoted.  Sprüssel et al (2012) also showed that peripheral blood granulocytopenia, 
monocytosis, anemia, and thrombocytopenia were reversible after restoration of LSD1 activity. 
During the recovery period, a dose-dependent increase of platelet counts was observed.  The 
maximum increase was about 3-fold compared to baseline values, and the peak time was 
approximately 14 days.  The platelet counts returned to baseline values approximately 28 days 
after INCB059872 treatment cessation. 
One dog administered 1 mg/kg QOD (the highest dose tested) in the 1-month study was 
euthanized; the cause of debilitation was an acute stomach ulcer.  Although similar 
gastrointestinal findings were not observed in other animals, the relationship of this finding to 
INCB059872 could not be excluded. 
There were no off-target toxicities identified in rats.  INCB059872 was negative in the Ames 
mutagenicity assay. 
The starting dose for this study was determined based on pharmacology-driven changes in bone 
marrow and peripheral blood (thrombocytopenia) in rats and dogs.  In the 1-month GLP rat 
study, the severely toxic dose in 10% (STD10) of rodents was above the highest tested dose of 
2.1 mg/kg QOD (12.6 mg/m2 per day).  In the 1-month dog study, because a relationship of the 
acute stomach ulcer to INCB059872 in the animal euthanized in extremis at 1 mg/kg could not

CONFIDENTIAL 
be excluded, the highest non−severely toxic dose (HNSTD) was considered to be 0.4 mg/kg 
(8 mg/m2 per day).  The human equivalent dose associated with these doses are 20.2 mg (rat) and 
13 mg (dog); applying a 10-fold safety factor for the rat and 6-fold safety factor in the dog results 
in doses of 2.02 mg and 2.17 mg, respectively.  Thus, a starting dose of 2 mg INCB059872 QOD 
was selected for this study; it is projected to provide exposures above the whole blood EC50 for 
LSD1 inhibition for approximately 2 hours, and thus expected to be pharmacologically active.  
The total AUC0-48 at this dose is projected to be 0.2 µM∙h, which is approximately 2.5-fold lower 
(female dogs) and approximately 18-fold lower (male rats) than the unbound AUC0-24 values for 
the HNSTD in dogs and STD10 in rats, as determined in the 1-month GLP studies. 
Taking into consideration that INCB059872 is a covalent inhibitor of LSD1, Cmax-based safety 
margins should also be considered: at 2 mg QOD, the human steady-state plasma Cmax is 
projected to be approximately 0.05 µM (approximately 0.037 µM, unbound), which is 
approximately 5.8-fold lower (female dog) and approximately 30-fold lower (male rats) than the 
unbound Cmax values for the HNSTD (dogs) and STD10 (rats), as determined in the 1-month GLP 
studies. 
In summary, the starting dose of 2 mg INCB059872 administered QOD is considered to be safe 
for subjects based on the following: 
• This dose was selected based on the overall toxicology assessment, including 
hematologic effects observed at the dog HNSTD and rat STD10, and applying 
appropriate safety factors.  These findings were not associated with evidence of 
extensive hemorrhage. 
• There are adequate exposure-based safety margins projected for both the AUC and 
the Cmax for the starting dose (2 mg). 
• The main toxicities (eg, thrombocytopenia, neutropenia, and anemia) are manageable 
in the clinic. 
• There is evidence for reversibility of all toxicities (eg, hematology and bone marrow 
effects). 
• There is a plan for comprehensive evaluation of safety before each dose escalation. 
1.6.2. 
Clinical Experience With INCB059872 
Part 1 (dose escalation), which determines the starting dose(s) of INCB059872 for dose 
expansion and combination therapy based on the MTD has been open and enrolling since 
MAY 2016.  Both QOD and QD schedules have been explored to collect safety, PK, and PD data 
to establish the optimal dose and schedule for patients with solid tumor and hematological 
malignancies.  The safety was closely monitored by assessments as described in throughout this 
Protocol as well as the frequency, duration, and severity of adverse events (AEs).  Patient status 
was discussed with the treating physicians during regular safety meetings.   
In Part 1, the initial 2 mg QOD dose was well-tolerated by subjects in both treatment groups, 
TG A (AML/MDS) and TGB (solid tumors).  As AML/MDS is a rapidly proliferating disease, it 
was decided in discussion with the participating investigators to use a daily dose (QD) schedule 
for TG A.  A total of 17 subjects have been treated in 4 different cohorts (3 at 2 mg QOD, 6 at

well-tolerated without any dose-limiting toxicities (DLTs).  The monotherapy recommended 
Phase 2 dose for AML/MDS subjects was determined to be 4 mg QD.  
In TG B, a total of 22 subjects have been treated in 6 different cohorts.  The QOD schedules included 
16 of those patients (3 at 2 mg QOD, 6 at 3 mg QOD, and 7 at 4 mg QOD) in 3 different cohorts.  
The QOD schedule was generally well-tolerated.  There was 1 DLT of Grade 4 thrombocytopenia at 
4 mg QOD.  Further dose escalation was stopped, and the next lower dose cohort of 3 mg QOD was 
expanded to treat a total of 6 patients.  No DLTs or Grade 3/4 thrombocytopenia were reported at 
3 mg QOD, and this dose is the recommended Phase 2 dose for solid tumors.  Dose escalation of the 
QD schedule in TG B has been halted due to 2 DLTs in the 3 mg QD cohort and 1 DLT in the 
2 mg QD cohort; however, a lower dose of 1 mg QD is currently ongoing.  Table 1 summarizes 
the number of subjects who enrolled in Study INCB 59872-101 by treatment cohort, as of the 
data cutoff date.

Preliminary unaudited data, as of 10 JUL 2017, are presented here for 39 subjects who have been 
treated with INCB059872 doses of 1 mg QD, 2 mg (QOD or QD), 3 mg (QOD or QD), and 4 mg 
(QOD or QD).  Eight subjects were receiving treatment as of the data cutoff date.  Of the 
39 subjects, 12 subjects have received INCB059872 for > 20 days, 14 subjects have received 
INCB059872 for > 30 days, and 6 subjects have received INCB059872 for > 90 days. 
Table 2 and Table 3 summarize TEAEs in descending order that occur in at least 3 subjects total 
for each treatment group.  The most frequent TEAEs among all dose cohorts in TG A were 
fatigue and nausea (6 subjects each).  The most frequent TEAEs among all dose cohorts in TG B 
were thrombocytopenia and dysgeusia (9 subjects each). 
Based on preclinical data generated to date, there is reason to believe that subjects may develop 
some level of thrombocytopenia.  As of the data cutoff date, 6 DLTs of ≥ Grade 3 
thrombocytopenia or platelet count decrease have been reported in the 2 mg QD, 3 mg QD, and

4 mg QOD cohorts in TG B (1, 2, and 3 respectively).  Treatment interruption occurred in the 
subjects with DLTs and resumed following recovery; 4 of these subjects resumed study 
treatment at a reduced dose (3 mg QOD). 
Four treatment-emergent serious adverse events (SAEs) resulted in discontinuation of study 
treatment:  thrombocytopenia, bile duct obstruction, epistaxis, and hypotension.  With the 
exception of thrombocytopenia, none of these TEAEs leading to INCB59872 discontinuation 
were considered related to study treatment.  Five treatment-emergent SAEs have resulted in 
death, none of which were considered related to study treatment by the investigators:  
leukocytosis, sepsis, pulmonary alveolar hemorrhage, respiratory failure, and gastrointestinal 
hemorrhage.

Potential Risks of All-Trans Retinoic Acid 
Boxed warnings for ATRA include retinoic acid−APL syndrome characterized by fever, 
dyspnea, acute respiratory distress, weight gain, radiographic pulmonary infiltrates, pleural and 
pericardial effusions, edema, and hepatic, renal, and multiorgan failure; rapidly evolving 
leukocytosis; and teratogenicity.  Evaluation and management should be performed as described 
in the package insert (Vesanoid 2010). 
Additional risks and precautions according to the package insert include headache, fever, dry 
skin, dry mucous membranes, bone pain, nausea and vomiting, rash, mouth sores, itching, 
sweating, eyesight changes, flu-like symptoms, coagulation disorder, infections, swelling of feet 
or ankles, bone/joint pain, and abdominal pain.  A complete discussion of risks associated with 
ATRA can be found at http://dailymed.nlm.nih.gov/.

1.6.4. 
Potential Risks of Azacitidine 
The primary DLT observed with azacitidine therapy is myelosuppression, typically manifesting 
as leukopenia, anemia, thrombocytopenia, and/or neutropenia.  Hematologic toxicities are 
reversible and are managed through dose interruptions and/or reductions.  Subjects will have 
blood counts monitored weekly during the first cycle of treatment and before starting each course 
of therapy thereafter, at a minimum.  Azacitidine has also been associated with severe adverse 
reactions, including hepatic coma and renal failure.  Subjects with significant baseline hepatic or 
renal impairment are excluded from this clinical study.  Additional adverse reactions associated 
with the use of azacitidine (≥ 20%) include nausea, vomiting, constipation, diarrhea, fever, 
dyspnea, petechiae, and ecchymosis.  A complete discussion of risks associated with azacitidine 
can be found at http://dailymed.nlm.nih.gov/. 
1.6.5. 
Potential Risks Associated With Nivolumab 
Due to the mechanism of action of nivolumab, immune-mediated adverse reactions have been 
seen when used as monotherapy and in combination with ipilimumab.  Guidance is provided in 
the package insert for the management of immune-mediated pneumonitis, immune-mediated 
colitis, immune-mediated hepatitis, immune-mediated endocrinopathies, immune-mediated 
nephritis and renal dysfunction, immune-mediated skin adverse reactions, and immune-mediated 
encephalitis.  Infusion reactions are also possible following administration of nivolumab.  The 
most common adverse reactions seen in ≥ 20% of patients receiving nivolumab monotherapy 
were fatigue, rash, musculoskeletal pain, pruritus, diarrhea, nausea, asthenic conditions, cough, 
dyspnea, constipation, decreased appetite, back pain, arthralgia, upper respiratory tract infection, 
and pyrexia.  The most common adverse reactions seen in ≥ 20% of subjects receiving 
nivolumab in combination with ipilimumab were fatigue, rash, diarrhea, nausea, pyrexia, 
vomiting, and dyspnea (Opdivo PI 2017).  Refer to the nivolumab prescribing information and 
EU summary of product characteristics for updated information regarding safety and risks.

INVESTIGATIONAL PLAN 
4.1. 
Overall Study Design 
This is an open-label, dose-escalation/dose-expansion study of the LSD1 inhibitor INCB059872 
as a monotherapy and combination therapy in subjects with advanced malignancies.  Subjects 
will receive INCB059872 doses QOD on a 28-day continuous therapy schedule; if QOD is 
well-tolerated, the next dose may be administered at a different dosing regimen (ie, QD) but will 
not exceed the 100% dose escalation for a total daily dose.  As illustrated in Figure 1, the study 
will be conducted in 4 parts:  Parts 1 and 2 will evaluate INCB059872 as monotherapy, with 
Part 1 for dose escalation and Part 2 for dose expansion, and Parts 3 and 4 will evaluate 
INCB059872 in combination with select therapies, with Part 3 for combination dose escalation 
and Part 4 for combination dose expansion.  Part 1 (monotherapy dose escalation) will determine 
the starting dose(s) of INCB059872 for dose expansion, based on MTD.  The recommended 
dose(s) will be taken forward into Part 2 (monotherapy dose expansion).  The initiation of Part 2 
will be based on further review of the ongoing clinical study and preclinical data of INCB059872 
and information from literature.  Part 3 (dose escalation of INCB059872 in combination therapy) 
will be initiated after the MTD in Part 1 is determined.  Part 4 (dose expansion of INCB059872 
in combination therapy) will explore the dose(s) confirmed in Part 3 and may be different based 
on combination therapy and/or tumor type. 
4.1.1. 
Monotherapy Dose Escalation (Part 1) 
Approximately 24 subjects will be enrolled into each dose-escalation treatment group. 
Treatment Group A will enroll subjects with AML or MDS.  The enrollment in TG B is 
prioritized for SCLC.  Enrollment of subjects with other solid malignancies (eg, endocrine 
tumors) is allowed with the sponsor medical monitor approval. 
Dose escalation for TG A and TG B in Part 1 will proceed independently, with each treatment 
group following a 3 + 3 design.  The starting dose of INCB059872 for TG A and TG B will be 
2 mg QOD.  A minimum of 3 subjects will initially be enrolled in each treatment group in Part 1, 
and each subject will be observed for a DLT observation period of 1 cycle (28 days) before the 
next dose cohort begins enrollment.  Subjects must have taken at least 75% of the cohort-specific 
dose (at least 11 doses for QOD schedule or at least 21 doses for QD schedule) in the first 
28 days of study treatment or have had a DLT to be considered evaluable.  Subjects who are not 
evaluable will be replaced.  The dose will be escalated by up to 100% if none (0) of the first 
3 evaluable subjects enrolled has a DLT.  Dose escalation should proceed in smaller increments 
(ie, by no more than 50%) if a DLT is observed, or if 2 or more subjects at a given dose level 
experience Grade 2 or higher AEs (unless they are clearly and incontrovertibly due to an 
alternative cause). 
If 1 of the first 3 evaluable subjects enrolled has a DLT, the cohort will be expanded to include 
3 additional evaluable subjects, and if no DLT occurs in the additional 3 subjects, then the dose 
will be escalated by up to 100%.  Otherwise, if 2 subjects in a cohort of 3 or 6 subjects 
experience DLTs, the MTD will be deemed to be exceeded.  An interim lower dose level may be 
explored if the dose increment has been 100%.  The MTD will be defined as 1 dose level below

CONFIDENTIAL 
the dose level at which one-third or more subjects experience DLTs.  Upon the aggregate review 
of overall safety, PK, 
and efficacy, a recommended dose (per tumor type) will be determined 
to maximize the clinical benefit/risk margin. 
4.1.2. 
Monotherapy Dose Expansion (Part 2)  
Upon identification of the recommended dose(s), up to 4 expansion cohorts per tumor type of 
approximately 15 subjects each may begin enrollment to further determine safety, tolerability, 
efficacy, PK, 
 of the selected dose(s).  Treatment Group A1 will enroll subjects with 
AML or MDS (based on emerging data, the sponsor may decide to enroll specific subtypes of 
AML).  Subjects in this A1 will have an opportunity to switch their treatment to a combination 
dose that is tested and found safe.  Only subjects who have stable disease or better response for 
≥ 3 months on monotherapy will be allowed to do so.  Treatment Group A2 will enroll subjects 
with MF (PMF, PPV-MF, and PET-MF).  Treatment Group B1 will enroll subjects with SCLC.  
Treatment Group B2 will enroll subjects with Ewing's sarcoma and poorly differentiated 
neuroendocrine tumors. 
The selected doses for each treatment group are as follows:  
• TG A1 dose will be 4 mg QD based on the safety and tolerability assessment in TG A 
(Part 1). 
• TG A2, TG B1, and TG B2 doses will be 3 mg QOD based on the safety and 
tolerability assessment in TG B (Part 1). 
A study of the effect of food on the PK of INCB059872 will be conducted in Part 2, TG B1 only. 
If ≥ 5 subjects in the first 15 subjects of any cohort cumulatively (or more than 33% of subjects 
in cohorts larger than 15 subjects) experience DLTs during Cycle 1, then further enrollment to 
the cohort will be stopped, and a lower dose level may be explored. 
Individual dose titration will be permitted according to Protocol-defined safety parameters.  
Subjects will continue to receive INCB059872 in 28-day cycles until a withdrawal criterion is 
met. 
4.1.3. 
Combination Dose-Finding (Part 3) 
Part 3 enrollment will be initiated after the MTD has been determined in Part 1 and will include 
dose-finding to evaluate safety and tolerability of the combinations.  Enrollment of Part 3 will 
occur in parallel with Part 2.  Dose-finding will use a 3 + 3 design to evaluate different doses of 
INCB059872 in combination with other therapies in the following treatment groups:  
• Combination TG C:  INCB059872 in combination with ATRA in subjects with 
relapsed/refractory AML.  The starting dose for INCB059872 in this cohort will be 
2 mg QD (2 dose levels below the recommended dose for monotherapy expansion in 
TG A1). 
• Combination TG D:  INCB059872 in combination with azacitidine in subjects with 
newly diagnosed, treatment-naive AML or MDS with at least 5% bone marrow blasts 
and IPSS-R intermediate or higher risk disease who are unfit to tolerate standard 
intensive chemotherapy at study entry and who are eligible to receive azacitidine as 
first-line therapy for the disease under study.  The starting dose for INCB059872 in 

Incyte Corporation 
Page 45 of 124 
Protocol INCB 59872-101 Am 8 
Version 8 
15 JUN 2020 
CONFIDENTIAL 
this cohort will be 2 mg QD (2 dose levels below the recommended dose for 
monotherapy expansion in TG A1). 
• Combination TG E:  INCB059872 in combination with nivolumab in subjects with 
advanced SCLC who previously progressed on platinum-based treatment.  The 
starting dose for INCB059872 in this cohort will be 3 mg QOD (the recommended 
dose for monotherapy expansion in TG B1). 
The starting dose of INCB059872 in the combination treatment groups was based upon the 
tolerability of INCB059872 monotherapy identified in Part 1 of this study.  Doses of the 
combination agents will be selected from conventional dose regimens and will remain the same 
for all dose-finding and dose-expansion cohorts.  INCB059872 doses will not exceed the 
monotherapy MTD identified in Part 1.  A minimum of 3 subjects will initially be enrolled in 
each treatment group in Part 3, and each subject will be observed for a DLT observation period 
of 1 cycle (28 days) before the next dose cohort or expansion to Part 4 begins enrollment.  
Subjects must have taken at least 75% of the cohort-specific dose (at least 11 doses for QOD 
schedule or at least 21 doses for QD schedule) in the first 28 days of study treatment or have had 
a DLT to be considered evaluable.  Subjects who are not evaluable will be replaced.  
If tolerated, the combination treatment groups will escalate independently and in parallel until 
the MTD or optimal doses of the combinations are identified and will be followed by 
independent expansion cohorts at the selected dose(s).  If the starting dose is not tolerated in any 
of the combination treatment groups, a lower dose of INCB059872 may be explored; otherwise, 
higher doses found to be safe and tolerable in Part 1 may be explored.  The sponsor, in 
consultation with participating investigators, may elect to expand a dose cohort(s) deemed 
tolerable, to up to 12 subjects, in order to obtain supplemental PK, 
, and safety data. 
4.1.4. 
Combination Dose Expansion (Part 4) 
Upon identification of the recommended dose(s) for each treatment combination in Part 3, 
expansion cohorts of approximately 30 subjects in each treatment group may begin enrollment to 
further determine safety, tolerability, efficacy, PK, 
 of the selected dose(s). 
• Combination TG C1:  INCB059872 in combination with ATRA using the regimen 
identified in Part 3 in subjects with relapsed/refractory AML. 
• Combination TG D1:  INCB059872 in combination with azacitidine using the 
regimen identified in Part 3 in subjects with newly diagnosed, treatment-naive AML 
or MDS with at least 5% bone marrow blasts and IPSS-R intermediate or higher risk 
disease who are unfit to tolerate standard intensive chemotherapy at study entry and 
who are eligible to receive azacitidine as first-line therapy for the disease under study. 
• Combination TG E1:  INCB059872 in combination with nivolumab using the 
regimen identified in Part 3 in subjects with advanced SCLC who previously 
progressed on platinum based treatment. 
In Part 4, a stopping rule for futility is planned for each combination dose expansion treatment 
group.  The futility analyses for combination TGs will be conducted when 15 subjects for each 
disease type have been treated and evaluated for response or have permanently discontinued 
study treatment because of disease progression, withdrawal of consent, or death.  The futility

Number of Subjects 
4.3.1. 
Planned Number of Subjects 
Approximately 215 subjects will be enrolled in this study as follows:  
• Part 1 will enroll approximately 24 subjects into each dose-escalation treatment 
group.  This may vary due to the number of cohorts required to determine the target 
dose(s).  
• Part 2, approximately 15 subjects will be enrolled in each of the 4 treatment groups.  
• Part 3 will enroll approximately 15 subjects total for all three treatment groups.  This 
number may vary due to the number of cohorts required to determine the optimal 
combination dose.  The sponsor, in consultation with participating investigators, may 
elect to expand a dose cohort(s) deemed tolerable, to up to 12 subjects, in order to 
obtain supplemental PK, 
, and safety data.  
• Part 4 will enroll approximately 30 subjects in TG C1, TG D1, and TG E1.  
4.3.2. 
Replacement of Subjects 
In Parts 1 and 3, if a subject is not evaluable (ie, did not receive at least 75% of cohort-specific 
dose within the first 28 days of study treatment), another subject will be enrolled at this dose 
level.  Subjects who report DLTs will be considered evaluable for the purpose of determining the 
safety and tolerability of the dose.  
4.4. 
Duration of Treatment and Subject Participation 
After signing the ICF, screening assessments may be completed over a period of up to 28 days.  
Each subject enrolled in the study may continue to receive study treatment in continuous 28-day 
cycles.  If the subject discontinues INCB059872, the treatment period will end and the subject 
will enter the follow-up period (see Section 6.4).  Study participation is expected to average 
approximately 6 months per individual subject. 
4.5. 
Overall Study Duration 
The study begins when the first subject signs the informed consent form.  The end of the study 
will occur when all subjects have discontinued study drug and have completed applicable 
follow-up assessments. 
If there have been ≤ 2 subjects on study for more than 6 months, a database lock of the study 
may occur to allow the analysis of the study data.  Any remaining subjects may continue to 
receive study treatment and be seen by the investigator per usual standard of care for this 
population.  The investigator will be expected to monitor for and report any SAEs, AEs of 
special interest, and pregnancies, as detailed in Section 8.  The remaining subjects are considered 
to be on study until a discontinuation criterion is met and written notification is provided to the 
sponsor.

Study Termination 
The investigator retains the right to terminate study participation at any time, according to the 
terms specified in the study contract.  The investigator is to notify the institutional review board 
(IRB)/independent ethics committee (IEC) in writing of the study's completion or early 
termination, send a copy of the notification to the sponsor or sponsor's designee, and retain 
1 copy for the site study regulatory file.

TREATMENT 
INCB059872 will be self-administered orally QOD or QD on a 28-day cycle.  In each cycle of 
the QOD dosing schedule, subjects should receive 14 doses of INCB059872.  In each cycle of 
the QD dosing schedule, subjects should receive 28 doses of INCB059872.  Tablets will be 
available in 1 mg strength.  The initial starting dose for Part 1 will be 2 mg QOD.  The initial 
starting dose for other parts of the study will be based on the aggregate data review of Part 1. 
For QOD administration, if a dose is missed by more than 24 hours, the subject should skip the 
dose and take the next scheduled dose at the usual time.  For QD administration, if a dose is 
missed by more than 4 hours, the subject should skip the dose and take the next scheduled dose 
at the usual time.  INCB059872 tablets should be taken on an empty stomach if possible (refrain 
from food consumption during the period 2 hours before and 1 hour after taking INCB059872).  
For subjects participating in the food-effect portion of the study in Part 2, TG B1, a high-fat, 
high-calorie meal will be consumed within 30 minutes before taking INCB059872 on Cycle 2 
Day 1. 
Alternative dosing regimens (ie, QD) may be explored based on emerging PK/
 and safety 
data. 
5.1. 
Treatment Assignment 
5.1.1. 
Subject Numbering and Treatment Assignment 
Study sites will enter subject demographic and baseline data into the Interactive Response 
Technology (IRT) in order to receive a subject number at the time of the subject enrollment.  
Sites will have to update the IRT system at each visit in order to receive the treatment allocation.  
All subject numbers will be 6 digits; the first 3 digits will be the site number, and the last 3 digits 
will be the subject's number.  This subject number will be maintained throughout the study and 
will not be reassigned.  Subjects who withdraw consent or discontinue from the study after being 
assigned a subject number will retain their initial number. 
This is a nonrandomized study; subjects will be assigned the same dose and treatment regimen in 
a particular treatment group.  The investigator or designee will pull the correct number of bottles 
of study drug from their stock and dispense the study drug to the subject.  All subsequent 
dispensing of study drug should follow this process.  Refer to the IRT manual for detailed 
information.

5.2.2. 
Conventional Care Drugs 
Every effort should be made by the sites to procure the commercially available and packaged 
product.  However, Incyte will provide certain reference therapy or therapies, such as tretinoin 
capsules or azacitidine or nivolumab where required by applicable law or regulation or under 
other limited circumstances when a subject may not otherwise have access to the therapy or 
therapies. 
5.2.2.1. 
Tretinoin Capsules 
In Parts 3 and 4 TG C and TG C1, Tretinoin (ATRA) capsules will be administered as an 
open-label commercial product in accordance with local prescribing information at a dose of 
45 mg/m2 per day.  The daily dose should be administered as 2 evenly divided doses.  Drug is 
available in 10 mg capsules and should be stored in accordance with the package insert.  Toxicity 
associated with tretinoin capsules will be managed per instruction in the package insert. 
5.2.2.2. 
Azacitidine 
In the Parts 3 and 4 TG D and TG D1, azacitidine will be administered in accordance with local 
prescribing information as an open-label commercial product at a starting dose of 75 mg/m2 SC 
or IV for 7 days during the first 9-day or less period (ie a 2-day break allowed on weekend, if 
needed) of each 28-day treatment cycle.  Toxicity associated with azacitidine dosing will be 
managed per instructions in the package insert (Vidaza PI 2014). 
Investigative sites must provide subjects with administration and storage instructions, as per 
package insert or institution standard, for azacitidine SC syringes dispensed to subjects for 
administration away from investigative site. 
5.2.2.3. 
Nivolumab 
Nivolumab will be administered at a dose of 3 mg/kg as an IV infusion over 60 minutes every 
2 weeks (Q2W).  Toxicity associated with immune reactions or infusion reactions will be 
managed following guidance in Sections 5.4.8 and 5.4.9. 
Nivolumab must be used in accordance with the storage conditions and shelf life in the 
manufacturer's approved label. 
5.3.

counts).  Subjects will be instructed to bring all study drugs with them to the study visits in order 
for site personnel to conduct tablet counts to assess study drug accountability.  The drug 
accountability documentation will be used by the sponsor to calculate treatment compliance. 
5.3.2. 
Treatment Compliance With ATRA, Azacitidine, and Nivolumab 
Compliance with ATRA will be calculated by the sponsor based on the drug accountability 
documented by the site staff and monitored by the sponsor/designee (tablet counts).  Subjects 
will be instructed to bring all study drugs with them to the study visits in order for site personnel 
to conduct tablet counts to assess study drug accountability.  The drug accountability 
documentation will be used by the sponsor to calculate treatment compliance. 
Azacitidine and nivolumab may be administered as an IV infusion by site personnel.  Receipt of 
infusions will be documented by the site staff and monitored by the sponsor/designee.  
Azacitidine may also be administered SC away from the investigative site and should be 
documented to ensure drug accountability. 
5.4. 
Treatment Interruptions and Adjustments 
5.4.1. 
Dose Modifications of INCB059872 
Selections and modifications to the study drug regimen are planned for dose-escalation cohorts.  
Dose interruptions and modifications also may occur for individual study subjects.  The 
identification of DLTs will define the doses used in planned cohorts.  Further, the occurrence of 
DLTs and other toxicities (related or unrelated to study drug) will guide decisions for treatment 
interruptions and discontinuation for individual subjects. 
Subjects enrolled in the dose-escalation portion of the study will have the option of escalating to 
a dose found to be tolerated in a subsequent cohort either within the same or alternative regimen. 
Subjects enrolled in TG C and TG D who have a bone marrow blast response (at least MFLS for 
AML, and CR or Marrow CR for MDS) may be able to explore different and less intensive 
dosing regimens to allow for hematologic recovery, especially platelet recovery, as approved by 
the medical monitor, such as switching from QD dosing to QOD dosing.  If the subject shows 
signs of losing the response and if deemed safe by the investigator, then the subject is allowed to 
revert to the prior dose and dosing schedule, but a more intensive dosing regimen than the 
starting dose is not allowed. 
Dosing modifications due to response only is not allowed during the DLT evaluation period.  In 
addition to dose interruption and reduction, dosing schedule modification (eg, switching from 
QD to QOD dosing) is also allowed for toxicity management per medical monitor approval. 
5.4.2. 
Dose Modifications of Conventional Care Agents 
Decisions regarding dose reduction of conventional care agents (ATRA, azacitidine, nivolumab) 
should be made following the guidelines in Table 5 and in consultation with the sponsor's 
medical monitor, taking into account relatedness of the AE to the study drug and the subject's 
underlying condition as well as in accordance with local prescribing information.

Management of Dose-Limiting Toxicities or Other Urgent Situations 
In all cases, investigators may employ any measures or concomitant medications, after 
discussion with the sponsor (whenever possible), necessary to optimally treat the subject. 
5.4.5. 
Follow-Up of Dose-Limiting Toxicities 
Any DLT should be followed until it resolves to baseline or appears to have stabilized for a 
minimum of 2 weeks.  During follow-up, subjects should be seen as often as medically indicated 
to assure safety. 
5.4.6. 
Procedures for Cohort Review and Dose Escalation 
Telephone conferences will be scheduled by the sponsor with study investigators in order to 
review cohort-specific data and overall safety data, to agree on dose escalation, adjudicate 
individual high-grade AEs as potentially dose-limiting, and guide other major study decisions. 
5.4.7. 
Criteria and Procedures for Dose Interruptions and Adjustments of 
INCB059872 
Study treatment may be delayed up to 2 weeks (14 days) to allow for resolution of toxicity with 
the exception of irAEs in subjects enrolled in TG E/E1 (see Table 6 for the management of 
irAEs).  Subjects may resume treatment if no medical condition or other circumstance exists that, 
in the opinion of the investigator, would make the subject unsuitable for further participation in 
the study.  The treating investigator should contact the sponsor to discuss the case of any subject 
whose treatment has been delayed for more than 14 days before restarting study treatment. 
Because subjects may enter the study with extensive pretreatment and/or severe bone marrow 
infiltration by the primary disease, these dose reduction rules are provided as guidelines (see 
Table 5).  Individual decisions regarding dose reduction should be made using clinical judgment 
and in consultation with the sponsor's medical monitor, taking into account relatedness of the AE 
to the study drug and the subject's underlying condition.  Adverse events that have a clear 
alternative explanation or transient (≤ 72 hours) abnormal laboratory values without associated 
clinically significant signs or symptoms may be exempt from dose-reduction rules.

Subjects should receive appropriate supportive care measures as deemed necessary by the 
treating investigator.  Suggested supportive care measures for the management of drug-related 
AEs with potential immunologic etiology are outlined in Table 6.  Detailed supportive care 
guidelines for specific irAEs can be in found in Appendix H.  Nivolumab may have specific 
irAE management guidelines within the package insert; the treating investigator may use labeled 
guidance or institutional guidelines for the management of irAEs if preferred.  For each AE, 
attempts should be made to rule out other causes, including but not limited to metastatic disease 
or bacterial or viral infection, which might require specific supportive care.

Management of Infusion Reactions 
Subjects in TG E/E1 may experience an infusion reaction associated with administration of study 
treatment.  Signs and symptoms usually develop during or shortly after drug infusion and 
generally resolve completely within 24 hours of completion of infusion.  Nivolumab infusion 
reactions should be managed according to guidance within the package insert; the treating 
investigator may use labeled guidance or institutional guidelines for the management of infusion 
reactions if preferred. 
5.4.10. 
Criteria for Permanent Discontinuation of INCB059872 
The occurrence of unacceptable toxicity not caused by the underlying malignancy will be 
presumed to be related to study drug treatment and will require that the study drug be 
permanently discontinued.  Unacceptable toxicity is defined as follows: 
• Occurrence of an AE that is related to treatment with the study drug that, in the 
judgment of the investigator or the sponsor's medical monitor, compromises the 
subject's ability to continue study-specific procedures or is considered to not be in the 
subject's best interest. 
• An AE requiring more than 2 dose reductions. 
• Persistent AE requiring a delay of therapy for more than 2 weeks (14 days) unless a 
greater delay has been approved by the sponsor. 
5.4.11. 
Criteria and Procedures for Dose Increases of INCB059872 
Intrasubject dose escalation will be permitted with sponsor preapproval in the following 
circumstances: 
• The Protocol eligibility criteria are met at the time of escalation. 
• The subject has received ≥ 4 cycles of study drug without drug-related toxicity 
≥ Grade 2. 
• The next higher dose level has been determined to be safe based on the MTD criteria. 
• The subject is willing to submit to the PK sampling and safety monitoring schedules 
as in Cycle 1 Day 15. 
• In the opinion of the investigator, the subject does not have any concurrent condition 
or circumstance that would complicate the dose escalation or PK sampling, or pose 
increased risk to the subject.

5.5. 
Withdrawal of Subjects From Study Treatment 
5.5.1. 
Withdrawal Criteria 
Subjects must be withdrawn from study drug for the following reasons: 
• The subject becomes pregnant. 
• Consent is withdrawn.  Note:  Consent withdrawn means that the subject can no 
longer be followed.  Subjects may choose to discontinue study treatment and remain 
in the study to be followed for disease progression. 
• Further participation would be injurious to the subject's health or well-being, in the 
investigator's medical judgment. 
• The study is terminated by the sponsor. 
• The study is terminated by the local health authority, IRB, or IEC. 
• Unacceptable toxicity has occurred. 
• Disease progression has occurred, except in the circumstance where, in the setting of 
otherwise stable disease, a medical procedure or radiation therapy is required to a 
single lesion, with medical monitor approval. 
A subject may be discontinued from study treatment as follows: 
• If, during the course of the study, a subject is found not to have met eligibility 
criteria, the medical monitor, in collaboration with the investigator, will determine 
whether the subject should be withdrawn from the study. 
• If a subject is noncompliant with study procedures or study drug administration in the 
investigator's opinion, the sponsor should be consulted for instruction on handling the 
subject. 
5.5.2. 
Withdrawal Procedures 
In the event that the decision is made to permanently discontinue the study drug, the last date of 
the last dose of study drug and the reason for subject withdrawal will be recorded in the eCRF.  
In addition, the following steps should be followed (Note:  These visits are described in 
Section 6): 
• The study monitor or sponsor must be notified. 
• The reason(s) for withdrawal must be documented in the subject's medical record and 
in the eCRF. 
• The EOT visit should be performed. 
• The date of the EOT visit should be recorded in the IRT. 
• Subjects must be followed for safety until the time of the follow-up visit or until 
study drug–related toxicities resolve, return to baseline, are deemed irreversible, or 
initiation of a new anticancer treatment, whichever occurs first.

CONFIDENTIAL 
If the subject discontinues study treatment and actively withdraws consent for collection of 
follow-up data (safety follow-up or disease assessment), then no additional data collection 
should occur; however, subjects will have the option of withdrawing consent for study treatment 
but continuing in the follow-up period of the study for safety/efficacy assessments. 
5.6. 
Concomitant Medications 
All concomitant medications and treatments must be recorded in the eCRF.  Any prior 
medication received up to 28 days before the first dose of study treatment and 30 days after the 
last dose of study treatment, or until the subject begins a new anticancer therapy, whichever 
occurs first, will be recorded in the eCRF. 
5.6.1. 
Restricted Medications 
• If concomitant administration of an anticoagulant/antiplatelet medication is indicated, 
caution and enhanced monitoring are required. 
− History of thrombocytopenia and any concurrent INCB059872-related 
thrombocytopenia should be a factor in the choice of anticoagulant and dose. 
• Hydroxyurea is restricted during the treatment periods of the study; however, it may 
be used to treat hyperleukocytosis per medical monitor approval. 
5.6.2. 
Prohibited Medications 
Subjects are prohibited from receiving the following therapies during the screening and treatment 
periods of this study: 
• Use of any anticancer drugs during study. 
• Hydroxyurea is prohibited within 48 hours before initiation of study treatment during 
the screening period and within 24 hours before collection of 
 
. 
• Aspirin in doses exceeding 81 mg/day. 
• Use of potent inhibitors of CYP2D6 or potent inhibitors or inducers of CYP3A4 
(Appendix B).

6.1. 
Screening 
Screening is the interval between signing the ICF and the day the subject is enrolled in the study 
(Cycle 1 Day 1).  Screening may not exceed 28 days.  Assessments that are required to 
demonstrate eligibility may be performed over the course of 1 or more days during the screening 
process. 
Procedures conducted as part of the subject's routine clinical management (eg, blood count, 
imaging study) and obtained before signing of informed consent may be used for screening or 
baseline purposes provided the procedure meets the Protocol-defined criteria and has been 
performed in the timeframe of the study (ie, within 28 days of Cycle 1 Day 1).  All information 
associated with eligibility requirements must be entered into the appropriate eCRF pages. 
Results from the screening visit evaluations will be reviewed to confirm subject eligibility before 
enrollment or the administration of study drug.  Tests with results that fail eligibility 
requirements may be repeated once during screening if the investigator believes the results to be 
in error.  For screening assessments that are repeated, the most recent available result before 
treatment assignment will be used to determine subject eligibility.  Treatment should start as 
soon as possible, but within 3 days after the date of enrollment.  Additionally, a subject who fails 
screening may repeat the screening process 1 time if the investigator believes there has been a 
change in eligibility status (eg, after recovery from an infection).  (Note:  For subjects who fail 
screening but are rescreened, a new subject number will be assigned.) 
6.2. 
Treatment 
The treatment period begins on the day the subject receives the first dose of study drug (Cycle 1 
Day 1) through the point at which the investigator determines the subject will be permanently 
discontinued from study drug.  Cycle 1 Day 1 must be no more than 28 days after the subject has 
signed the ICF and no more than 3 days after the date of registration.  Dates for subsequent study 
visits will be determined based on this day and should occur within the specified visit windows 
noted in Table 7 and Table 8 of the scheduled date unless delayed for safety reasons.  At Cycle 1 
Day 1, results from screening visit evaluations should be reviewed to determine whether the 
subject continues to meet the eligibility requirements, as specified in Section 3. 
Note:  Day 15 visits beyond Cycle 4 may be optional (except for subjects in TG E/E1) per 
subject overall status and approval by the sponsor medical monitor. 
6.3. 
End of Treatment 
When the subject permanently discontinues study drug, the EOT visit should be conducted.  If 
the EOT visit coincides with a regular study visit, the EOT evaluations will supersede those of 
that scheduled visit, and the data should be entered in the EOT visit in the eCRF.  The subject 
should be encouraged to return for the follow-up visit.

6.4. 
Follow-Up 
6.4.1. 
Safety Follow-Up 
The safety follow-up period is the interval between the EOT visit and the scheduled follow-up 
visit, which should occur 30 to 35 days after the EOT visit (or after the last dose of study drug if 
the EOT visit was not performed).  Note that subjects will be required to submit to twice weekly 
blood draws in the 2 weeks after the last dose of study drug. 
Adverse events and SAEs must be reported up until at least 30 days after the last dose of study 
drug, the date of the follow-up visit, or until toxicities resolve, return to baseline, are deemed 
irreversible, or the subject initiates a new anticancer treatment, whichever occurs first.  
Reasonable efforts should be made to have the subject return for the follow-up visit and report 
any AEs that may occur during this period.   
If a subject is scheduled to begin a new anticancer therapy before the end of the 30-day safety 
follow-up period, the safety follow-up visit should be performed before new anticancer therapy 
is started. 
6.4.2. 
Disease Status Follow-Up 
Subjects who discontinue study treatment for a reason other than disease progression will move 
into the disease status follow-up period and should be assessed every 8 to 9 weeks by radiologic 
imaging (SCLC/solid tumors) or blood/bone marrow assessment (AML/MDS/MF) to monitor 
disease status.  Every effort should be made to collect information regarding disease status until 
(whichever occurs first): 
• The start of new antineoplastic therapy. 
• Disease progression. 
• Death. 
• The end of the study. 
6.5. 
End of Study 
The end of the study may be designated as the timepoint when all subjects have discontinued the 
study or the sponsor terminates the study.

CONDUCT OF STUDY ASSESSMENTS AND PROCEDURES 
7.1. 
Administration of Informed Consent Form 
Valid informed consent must be obtained from the study subject before conducting any 
study-specific procedures using an ICF approved by the local IRB/IEC that contains all elements 
required by ICH E6, and describes the nature, scope, and possible consequences of the study in a 
form understandable to the study subject.  Local and institutional guidelines for ICF content and 
administration must be followed; the original signed ICF must be retained by the investigator, 
and a copy of the signed ICF must be provided to the study subject.  The informed consent 
process for each subject must be documented in writing within the subject source documentation. 
7.2. 
Interactive Response Technology Procedure 
The IRT will be contacted to obtain a subject ID number when a subject enters screening.  Upon 
determining that the subject is eligible for study entry, the IRT will be contacted to enroll the 
subject.  Additionally, the IRT will be contacted at each regular study visit to update the study 
drug supply and cohort management. 
7.3. 
Demography and Medical History 
7.3.1. 
Demographics and General Medical History 
Demographic data and general medical history will be collected at screening. 
7.3.2. 
Disease Characteristics and Treatment History 
A disease-targeted medical and medication history will be collected at screening. 
7.4. 
Prior and Concomitant Medications and Procedures 
Prior and concomitant medications and procedures will be reviewed to determine subject 
eligibility.  All concomitant medications and measures must be recorded in the eCRF, and any 
medication received or procedure performed within 30 days before enrollment and up to the end 
of study will be recorded in the eCRF.  The medication record will be maintained after signing 
the ICF to document concomitant medications, including any changes to the dose or regimen.  
Concomitant medications include any prescription, over-the-counter, or natural/herbal 
preparations taken or administered during the study period.  Concomitant treatments and/or 
procedures that are required to manage a subject's medical condition during the study will also be 
recorded in the eCRF. 
7.5. 
Safety Assessments 
7.5.1. 
Adverse Events 
Adverse events will be monitored from the time the subject signs the ICF.  Subjects will be 
instructed to report all AEs during the study and will be assessed for the occurrence of AEs 
throughout the study.  In order to avoid bias in eliciting AEs, subjects will be asked general,

recorded on the source documents and eCRFs regardless of the assumption of a causal 
relationship with the study drug.  The definition, reporting, and recording requirements for AEs 
are described in Section 8. 
7.5.2. 
Physical Examinations 
Clinically notable abnormalities that are considered clinically significant in the judgment of the 
investigator are to be reported as AEs. 
Physical examinations must be performed by a medically qualified individual such as a licensed 
physician, physician's assistant, or a nurse practitioner, as local law permits. 
Clinically notable abnormalities that are considered clinically significant in the judgment of the 
investigator are to be reported as AEs. 
7.5.2.1. 
Comprehensive Physical Examination 
The comprehensive physical examination performed at screening will include height and body 
weight, and assessment(s) of the following organ or body systems:  skin; head, eyes, ears, nose, 
and throat; thyroid; lungs; cardiovascular system; abdomen (liver, spleen); extremities; and 
lymph nodes; as well as a brief neurological examination. 
7.5.2.2. 
Targeted Physical Examination 
The targeted physical examination performed at all other visits will be a symptom-directed 
evaluation.  The targeted physical examination will include body weight and assessment(s) of the 
body systems or organs, as indicated by subject symptoms, AEs, or other findings. 
7.5.3. 
Vital Signs 
Vital sign measurements include blood pressure, pulse, respiratory rate, and body temperature.  
Blood pressure and pulse will be taken with the subject in the recumbent, semirecumbent, or 
sitting position after 5 minutes of rest.  Clinically notable abnormalities that are considered 
clinically significant in the judgment of the investigator are to be reported as AEs. 
7.5.4. 
Electrocardiograms 
All 12-lead ECGs will be performed with the subject in a recumbent or semirecumbent position 
after 5 minutes of rest.  A single ECG is performed at the screening, EOT, and safety follow-up 
visits.  Triplicate ECGs are performed on Cycle 1 Day 1 and Cycle 1 Day 15 at predose and 1, 2, 
and 6 hours postdose.  A triplicate ECG is performed on Cycle 1 Day 8 approximately 24 hours 
after the last dose on Day 7; if a subject is being seen on Day 7 or Day 9 (study drug 
administration days), triplicate ECG should be performed before study drug administration.  
Note that triplicate ECGs should be performed with a 2- to 5-minute break between evaluations.  
Note that the timed schedule may change per emerging PK data. 
The 12-lead ECGs will be interpreted by the investigator at the site to be used for immediate 
subject management; all ECGs will be collected and reviewed by a central ECG vendor.  The 
decision to include or exclude a subject or withdraw a subject from the study based on an ECG 
flagged as "Abnormal, Clinically Significant" is the responsibility of the investigator, in

consultation with the sponsor's medical monitor, as appropriate.  Clinically notable abnormalities 
that are considered clinically significant in the judgment of the investigator are to be reported as 
AEs. 
7.5.5. 
Laboratory Assessments 
Sites will use their local laboratories for eligibility and ongoing safety assessments.  Chemistry, 
hematology, coagulation panel, serology, lipid panel, and urinalysis will all be analyzed. 
For MF subjects only:  after 24 weeks, D15 visits of each cycle can be omitted, with medical 
monitor approval.  
7.5.5.1. 
Pregnancy Testing 
A pregnancy test will be required for all women of childbearing potential during screening, on 
Day 1 (before the first dose of study drug) and at the end of treatment visit.  Serum or urine 
pregnancy tests will be conducted as outlined in Table 8, as medically indicated, or per 
country-specific requirement.  Urine pregnancy tests will be done locally.  If a urine pregnancy 
test is positive, the results should be confirmed with a serum pregnancy test. 
If the serum pregnancy test is negative after a urine test was positive, the investigator will assess 
the potential benefit/risk to the subject and determine whether it is in the subject's best interest to 
resume study drug and continue participation in the study. 
7.6. 
Efficacy Assessments 
Objective assessment of tumor status is required using appropriate disease-specific techniques, 
and the investigator's assessment will be used to determine responses and will be logged into the 
eCRF.  For SCLC/solid tumors subjects, Response Evaluation Criteria in Solid Tumors 
(RECIST) v1.1 (Eisenhauer et al 2009) will be used, and the recommended method for 
measuring and following tumor burden will be CT scan or MRI, to include the thorax, abdomen, 
and pelvis; the neck can be included if needed.  Alternative modalities may be substituted for a 
CT scan at the discretion of the investigator, provided that the same modality is used throughout 
the study and the methodology is consist with RECIST v1.1. 
For AML subjects, the International Working Group Response Criteria for Acute Myeloid 
Leukemia (Cheson et al 2003, Appendix D) will be used as the recommended method for 
measuring and following disease status.  For MDS subjects, International Working Group 
Response Criteria for MDS (Cheson et al 2006, Appendix F) will be used as the recommended 
method for measuring and following disease status.  For MF subjects, the proposed Response 
Criteria for MF (Tefferi et al 2013, Appendix G) will be used as the recommended method for 
measuring and following disease status. 
The schedule for disease assessments will be at screening (this will be considered the baseline 
assessment) for all subjects and then once every 8 weeks throughout the study for solid tumor 
and once every 4 weeks for AML/MDS.  The schedule for MF disease assessments will be at 
screening (this will be considered the baseline assessment), once every 4 weeks until Week 24, 
and once every 12 weeks after Week 24.  For subjects who discontinue treatment for reasons 
other than disease progression, every effort should be made to continue monitoring their disease

status until the start of new anticancer therapy, documented disease progression, death, or end of 
study, whichever occurs first. 
Bone marrow examination (aspirate and biopsy) is required at screening for subjects with 
diseases that are typically monitored through bone marrow examination, including AML, MDS, 
and MF.  Note:  subjects with a history of allogenic hematopoietic stem cell transplantation 
should have bone marrow collected and analyzed locally for the purposes of determining disease 
status (where applicable); however their sample does not need to be processed for sequencing 
due to chimeric potential. 
Data from the pathology report result from the bone marrow examination will be captured in the 
eCRF.  All bone marrow examinations should include a unilateral aspiration and biopsy with 
FISH and cytogenetic testing, when feasible and indicated.  Subjects may be enrolled based on a 
biopsy only when a "packed marrow" precludes aspiration at the decision of the medical monitor. 
Results of assessments performed under standard of care before the signing of informed consent 
may be used as the baseline disease assessment in lieu of a study-specific procedure if performed 
within 60 days of the first dose of study drug (Cycle 1 Day 1) and if adequate archive material is 
available and there has been no anticancer therapy in the interim. 
For disease assessment timepoints in AML, MDS, and MF that do not correspond to a bone 
marrow examination, peripheral blood myeloid blast percentage will be evaluated by 
microscopic evaluation or other appropriate methodology and will be used as appropriate in 
conjunction with other parameters (eg, cytopenias) in determining disease status. 
For AML and MDS subjects, a bone marrow disease assessment is strongly encouraged during 
Cycle 2, preferably at Cycle 2 Day 1 for subjects who have a significant circulating blast count 
reduction (as determined by the investigator), including subjects who are not completely cleared 
of circulating blasts; a bone marrow biopsy and/or aspirates for response is to be performed at 
Cycle 4 Day 1 or earlier as clinically indicated, followed by every other month as clinically 
indicated, or upon circulating blood cell recovery to assess antileukemic activity (cytogenetic 
testing is not required if CR is not presented).  Bone marrow examination schedule can be 
modified with approval from the medical monitor. 
For MF subjects, bone marrow biopsy must be completed at screening or baseline visit, unless 
biopsy and data from previous 2 months are available.  Additional biopsies will be performed at 
Week 24, Week 48, and every 24 weeks.  If a biopsy is not possible or contraindicated, or the 
tissue requirement cannot be satisfied, this requirement may be waived with approval from the 
medical monitor.  
For MF subject disease assessment with spleen palpation:  spleen length will be assessed by 
manual palpation at every study visit (laboratory-only visits not included) and will be used for 
routine subject management.  Investigators should use a soft centimeter ruler so that palpable 
spleen length is measured in centimeters and not in finger breadths.  The edge of the spleen shall 
be determined by palpation and measured in centimeters, using a soft ruler, from the costal 
margin to the point of greatest splenic protrusion.  Spleen length must be recorded on the CRF.

Pharmacokinetic Assessments 
7.8.1. 
Blood Sample Collection 
Pharmacokinetic samples will be obtained at the visits indicated in the Schedule of Laboratory 
Assessments (Table 8) to evaluate plasma PK parameters as described in Appendix C.  For PK 
sample collection, the following will be recorded:  
• The exact date and time of the blood sample.  
• The date and time of the last dose of study drug before blood collection (if 
applicable).  
• The time of the most recent meal.  
Subjects will receive reminder cards in advance of the study visit providing instructions to 
prepare for the visit (see Section 7.10.1).  Instructions for plasma preparation and sample 
shipping will be provided in the Laboratory Manual. 
7.8.1.1. 
Timed Pharmacokinetic Testing 
Timed PK testing will be performed using the timepoints shown in Table 10.  The timing of PK 
sample collection may be coordinated with other timed tests (
 ECG).  On these 
study dates, the subject should arrive at the research unit in the morning.  If study drug has been 
previously dispensed, the reminder card (see Section 7.10.1) will remind the subject to refrain 
from taking the study drug at home that day.  Subjects will also be reminded about fasting 
requirements, as applicable (see Table 10).  A trough (predose) PK sample will be collected early 
in the study visit, followed by administration of the study drug and subsequent timed blood 
samples.  The study drug will be administered with approximately 240 mL of water.  Subjects 
should remain fasting from food or water for at least 1 hour postdose, after which a meal or 
snack may be consumed.

their morning dose of study drug on Days 1, 8, 15, or 22 of Cycle 1 and then Days 1 and 15 for 
all other cycles, as they will take it after blood draws for safety evaluation have been completed.  
The reminder cards will have an area on which the date and time of the last dose taken (from the 
previous evening) and the time of their last meal before the visit should be recorded. 
8. 
SAFETY MONITORING AND REPORTING 
8.1. 
Adverse Events 
8.1.1. 
Definitions 
For the purposes of this Protocol, an AE is defined as any untoward medical occurrence 
associated with the use of a drug in humans, whether or not considered drug related, that occurs 
after a subject provides informed consent.  Abnormal laboratory values or test results occurring 
after informed consent constitute AEs only if they induce clinical signs or symptoms, are 
considered clinically meaningful, require therapy (eg, hematologic abnormality that requires 
transfusion), or require changes in the study drug(s). 
8.1.2. 
Reporting 
Adverse events that begin or worsen after informed consent should be recorded on the Adverse 
Events form of the eCRF.  Conditions that were already present at the time of informed consent 
should be recorded on the Medical History form in the eCRF.  Monitoring for the occurrence of 
new AEs should be continued for at least 30 days after the last dose of study drug.  Adverse 
events (including laboratory abnormalities that constitute AEs) should be described using a 
diagnosis whenever possible rather than by individual underlying signs and symptoms.  When a 
clear diagnosis cannot be identified, each sign or symptom should be reported as a separate AE. 
The term "disease progression" should be recorded as an AE/SAE only if there are no other 
identifiable AEs/SAEs associated with the disease progression at the time of reporting.  For 
events associated with disease progression, the relevant signs and symptoms should be reported 
using a diagnosis whenever possible rather than individual underlying signs and symptoms.  
When a clear diagnosis cannot be identified, each sign or symptom should be reported as a 
separate AE.  If the events resulting from disease progression meet the criteria for an SAE 
(eg, resulted in hospitalization, a life-threatening event, or death), the specific events(s) should 
be reported as an SAE(s) as described in Section 8.3.2.  In both cases (ie, AEs or SAEs related to 
disease progression), it should be indicated that each event (reported as a diagnosis or as signs 
and symptoms) is related to disease progression on the Adverse Events form of the eCRF. 
The severity of AEs will be assessed using CTCAE v4.03 Grades 1 through 4.  The CTCAE 
v4.03 severity of Grade 5 will not be used; AEs resulting in death will be graded accordingly 
using Grades 1 through 4 and have the outcome noted as fatal.  If an event is not classified by 
CTCAE the severity of the AE will be graded according to the scale below to estimate the grade 
of severity: 

Incyte Corporation 
Page 76 of 124 
Protocol INCB 59872-101 Am 8 
Version 8 
15 JUN 2020 
CONFIDENTIAL 
Grade 1 
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; 
intervention not indicated. 
Grade 2 
Moderate; minimal, local, or noninvasive intervention indicated; limiting 
age-appropriate activities of daily living. 
Grade 3 
Severe or medically significant but not immediately life-threatening; hospitalization 
or prolongation of hospitalization indicated; disabling; limiting self-care activities of 
daily living. 
Grade 4 
Life-threatening consequences; urgent intervention indicated. 
The occurrence of AEs should be sought by nondirective questioning of the subject during the 
screening process after signing the ICF and at each visit during the study.  Adverse events may 
also be detected when they are volunteered by the subject during the screening process or 
between visits, or through physical examination, laboratory test, or other assessments.  To the 
extent possible, each AE should be evaluated to determine: 
• The severity grade (CTCAE Grade 1 to 4). 
• Whether there is at least a reasonable possibility that the AE is related to the study 
treatment:  suspected (yes) or not suspected (no). 
• The start and end dates, unless unresolved at final follow-up. 
• The action taken with regard to study drug. 
• The event outcome (eg, not recovered/not resolved, recovered/resolved, 
recovering/resolving, recovered/resolved with sequelae, fatal, unknown). 
• The seriousness, as per serious AE (SAE) definition provided in Section 8.3.1. 
Unlike routine safety assessments, SAEs are monitored continuously and have special reporting 
requirements (see Section 8.3.2). 
All AEs should be treated appropriately.  If an AE is treated with a concomitant medication or 
nondrug therapy, this action should be recorded on Adverse Event form and the treatment should 
be specified on the Prior/Concomitant Medications or Procedures and Non-Drug Therapy form 
in the eCRF. 
Once an AE is detected, it should be followed until it has resolved or until it is judged to be 
permanent; assessment should be made at each visit (or more frequently if necessary) of any 
changes in severity, the suspected relationship to the study drug, the interventions required to 
treat the event, and the outcome. 
When the severity of an AE changes over time for a reporting period (eg, between visits), each 
change in severity will be reported as a separate AE until the event resolves.  For example, 
2 separate AEs will be reported if a subject has Grade 1 diarrhea, meeting the definition of an 
AE, that lasts for 3 days before worsening to a Grade 3 severity.  The Grade 1 event will be 
reported as an AE with a start date equal to the day the event met the Grade 1 AE definition and 
a stop date equal to the day that the event increased in severity from Grade 1 to Grade 3.  The 
Grade 3 event will also be reported as an AE, with the start date equal to the day the event 
changed in intensity from Grade 1 to Grade 3 and a stop date equal to the day that the event 
either changed severity again or resolved.

8.2. 
Laboratory Test Abnormalities 
Laboratory abnormalities that constitute an AE in their own right (considered clinically 
meaningful, induce clinical signs or symptoms, require concomitant therapy, or require changes 
in study drug) should be recorded on the Adverse Event form in the eCRF.  Whenever possible, a 
diagnosis rather than a symptom should be provided (eg, "anemia" instead of "low hemoglobin").  
Laboratory abnormalities that meet the criteria for AEs should be followed until they have 
returned to normal or an adequate explanation of the abnormality is found.  When an abnormal 
laboratory test result corresponds to a sign or symptom of a previously reported AE, it is not 
necessary to separately record the laboratory test result as an additional event. 
Laboratory abnormalities that do not meet the definition of an AE should not be reported as AEs.  
A Grade 3 or 4 (severe) AE does not automatically indicate an SAE unless it meets the definition 
of serious, as defined in Section 8.3.1.  A dose modification for the laboratory abnormality may 
be required (see Section 5.4) and should not contribute to the designation of a laboratory test 
abnormality as an SAE. 
8.3. 
Serious Adverse Events 
8.3.1. 
Definitions 
An SAE is defined as an event that meets at least 1 of the following criteria: 
• Is fatal or life-threatening. 
• Requires inpatient hospitalization or prolongation of existing hospitalization, unless 
hospitalization is a result of: 
− A routine treatment or monitoring of the studied  tumor type not associated with 
any deterioration in condition (ie, bone marrow biopsy for AML subjects) 
− An elective surgery or preplanned treatment for a pre-existing condition that is 
unrelated to the tumor type under study and has not worsened since signing the 
ICF. 
− A treatment on an emergency outpatient basis for an event not fulfilling any of the 
definitions of a SAE and not resulting in hospital admission. 
− Any social reasons and respite care, in the absence of any deterioration in the 
subject's general condition. 
• Results in persistent or significant disability, incapacity, or a substantial disruption of 
a person's ability to conduct normal life functions. 
• Constitutes a congenital anomaly or birth defect. 
• Is considered to be an important medical event or a medically significant event that 
may not result in death, be immediately life-threatening, or require hospitalization but 
may be considered serious when, based on appropriate medical judgment, the event 
may jeopardize the subject or may require medical or surgical intervention to prevent 
one of the outcomes listed above.

8.3.2. 
Reporting 
Every SAE, regardless of suspected causality (eg, relationship to study drug(s) or study 
procedure or disease progression), occurring after the subject has signed the ICF through the last 
study visit (or 30 days after the last dose of study drug, whichever is later) must be reported to 
the sponsor (or designee) within 24 hours of learning of its occurrence, unless otherwise 
specified by the Protocol.  Any SAEs occurring more than 30 days after the last dose of study 
drug should be reported to the sponsor it its designee only if the investigator suspects a causal 
relationship to the study drug.   
Information about all SAEs is collected and recorded on the Adverse Event form of the eCRF.  
The investigator must assess and record the causal relationship of each SAE to the study 
treatment. 
The investigator must also complete the Incyte Serious Adverse Event Report Form, in English, 
and send the completed and signed form to the sponsor or designee within 24 hours of becoming 
aware of the SAE.  The investigator must provide a causality assessment, that is, assess whether 
there is at least a reasonable possibility that the SAE is related to the study treatment:  suspected 
(yes) or not suspected (no).  Refer to the Incyte Reference Guide for Completing the Serious 
Adverse Event Report Form. 
The contact information of the sponsor's study-specific representatives is listed in the 
investigator manual provided to each site.  The original copy of the SAE Report Form and the 
confirmation sheet must be kept at the study site. 
Investigational site personnel must report any new information regarding the SAE within 
24 hours of becoming aware of the information in the same manner that the initial SAE Report 
Form was sent.  Follow-up information is recorded on an amended or new SAE Report Form, 
with an indication that it is follow-up to the previously reported SAE and the date of the original 
report.  The follow-up report should include information that was not provided on the previous 
SAE Report Form, such as the outcome of the event (eg, resolved or ongoing), treatment 
provided, action taken with study drug because of the SAE (eg, dose reduced, interrupted, or 
discontinued), or subject disposition (eg, continued or withdrew from study participation).  Each 
recurrence, complication, or progression of the original event should be reported as follow-up to 
that event, regardless of when it occurs. 
If the SAE is not documented in the IB for the study drug (new occurrence) and is thought to be 
related to the sponsor's study drug, the sponsor or its designee may urgently require further 
information from the investigator for reporting to health authorities.  The sponsor or its designee 
may need to issue an Investigator Notification (IN) to inform all investigators involved in any 
study with the same drug that this SAE has been reported.  Suspected Unexpected Serious 
Adverse Reactions (SUSARs) will be collected and reported to the competent authorities and 
relevant ethics committees in accordance with Directive 2001/20/EC, or as per national 
regulatory requirements in participating countries.

8.5. 
Pregnancy 
Pregnancy, in and of itself, is not regarded as an AE unless there is suspicion that study drug may 
have interfered with the effectiveness of a contraceptive medication or method.  When a 
pregnancy has been confirmed in a subject during maternal or paternal exposure to study drug, 
the following procedures should be followed in order to ensure subject safety: 
• The study drug must be discontinued immediately (female subjects only; see 
Section 5.4.7 for the maximum permitted duration of study drug interruption). 
• The investigator must complete and submit the Incyte Clinical Trial Pregnancy form 
to the sponsor or its designee within 24 hours of learning of the pregnancy. 
Data on fetal outcome and breastfeeding are collected for regulatory reporting and drug safety 
evaluation.  Follow-up should be conducted for each pregnancy to determine outcome, including 
spontaneous or voluntary termination, details of the birth, and the presence or absence of any 
birth defects, congenital abnormalities, or maternal and/or newborn complications, by following 
until the first well-baby visit.  Pregnancy should be recorded on a Clinical Trial Pregnancy form 
and reported by the investigator to the sponsor or its designee.  Pregnancy follow-up information 
should be recorded on the same form and should include an assessment of the possible causal 
relationship to the sponsor's study drug to any pregnancy outcome, as well as follow-up to the 
first well-baby visit or the duration specified in local regulations, whichever is later.  Refer to the 
Incyte Reference Guide for Completing the Clinical Trial Pregnancy Form. 
Any SAE occurring during pregnancy must be recorded on the SAE report form and 
submitted to the sponsor or designee. 
8.6. 
Warnings and Precautions 
Special warnings or precautions for the study drug, derived from safety information collected by 
the sponsor or its designee, are presented in the Investigator's Brochure (IB).  Additional safety 
information collected between IB updates will be communicated in the form of Investigator 
Notifications (INs).  Any important new safety information should be discussed with the subject 
during the study, as necessary.  If new significant risks are identified, they will be added to the 
ICF. 
8.7. 
Data Monitoring Committee 
No independent Data Monitoring Committee is planned for this study.  Decisions to continue the 
enrollment in subsequent dose level cohort, dose level to be tested, as well as number of subjects 
to be evaluated, will be made after the appropriate data are collected and reviewed by sponsor 
representatives (eg, medical monitor) and investigators or designees.  The group of sponsor 
representatives and investigators or designees will convene regularly (eg, once weekly) or ad hoc 
for specific discussions.  Meeting minutes will be documented. 
An internal Data Safety Monitoring Board (iDSMB) will review safety data at regular intervals 
throughout the study.  The frequency of meetings will be contingent upon enrollment and 
availability of safety data for analysis and review.  Details regarding membership, roles, and 
responsibilities of the committee are specified in the iDSMB charter.

Product Complaints 
The sponsor collects product complaints on study drugs and drug delivery systems used in 
clinical studies in order to ensure the safety of study participants, monitor quality, and facilitate 
process and product improvements. 
All product complaints associated with material packaged, labeled, and released by the sponsor 
or its designee will be reported to the sponsor.  All product complaints associated with other 
study material will be reported directly to the respective manufacturer. 
The investigator or his/her designee is responsible for reporting a complete description of the 
product complaint via email or other written communication to the sponsor contact or respective 
manufacturer as noted in the packaging information.  Any AE associated with a product 
complaint should be reported as described in Section 8.1.2 of this Protocol. 
If the investigator is asked to return the product for investigation, he/she will return a copy of the 
product complaint communication with the product.

STATISTICS 
9.1. 
Study Populations 
The populations to be analyzed include the following: 
• The full analysis set/safety population consists of subjects enrolled in the study who 
received at least 1 dose of study drug. 
• The PK/
 population consists of all enrolled subjects who had PK/
 data. 
9.2. 
Selection of Sample Size 
Part 1 and Part 3 of the study will use a standard 3 + 3 dose-escalation design, and the sample 
size will depend on the frequency of DLTs and the number of dose-escalation cohorts before 
reaching the MTD.  Approximately 3 to 6 subjects will be enrolled in each dose level.  Using this 
design, the probability of dose escalation for various DLT rates is given in Table 11.

Clinical Laboratory Tests 
Laboratory test values outside the normal range will be assessed for severity based on the normal 
ranges for the clinical reference laboratory.  The incidence of abnormal laboratory values and 
shift tables relative to baseline will be tabulated. 
Laboratory data will be classified into Grades 1 through 4 using CTCAE v4.03.  The following 
summaries will be produced for the laboratory data: 
• Number and percentage of subjects with worst postbaseline CTCAE grade (regardless 
of baseline value).  Each subject will be counted only for the worst grade observed 
postbaseline. 
• Shift tables from baseline to the worst postbaseline value will be produced using 
CTCAE grade. 
• For laboratory parameters where CTCAE grades are not defined, shift tables to the 
worst postbaseline value using the low/normal/high classifications based on 
laboratory reference ranges. 
9.4.3.3. 
Vital Signs 
Descriptive statistics and mean change from baseline will be determined for vital signs (blood 
pressure, pulse, respiratory rate, and body temperature) at each assessment time.  Vital sign 
results will be reviewed for clinically notable abnormalities (see Table 12), and subjects 
exhibiting clinically notable vital sign abnormalities will be listed.  A value will be considered an 
"alert" value if it is outside the established range and shows a > 25% change from baseline.

9.4.3.5. 
Adverse Events of Special Interest 
Based on preclinical data generated to date, there is reason to believe that subjects will develop 
some level of thrombocytopenia.  No human data have been generated yet to support this.  
Additionally, there is a chance for a "rebound" effect on platelets (potentially thrombocytosis) 
once the drug is discontinued, but human data have not been generated to support this effect.  
Subjects will be monitored closely and based on CTCAE grading of thrombosis will be reported 
as AEs as appropriate. 
9.4.4. 
Pharmacokinetic Analysis 
The PK parameters of Cmax, Tmax, Cmin, AUC0-t, t½, and Cl/F (INCB059872) will be calculated 
from the blood plasma concentrations of INCB059872 using standard noncompartmental 
(model-independent) PK methods.  Pharmacokinetic calculations will be performed, if 
appropriate, using commercial software such as WinNonlin®.  Nominal times will be used in all 
cases, except when the difference between the actual time and nominal time is greater than 
15 minutes for samples collected up to 4 hours after administration and greater than 30 minutes 
for samples collected more than 4 hours after administration; in these cases, actual time will be 
used for PK analysis.  Refer to Appendix C for a detailed list and description of the PK 
parameters. 
If there is a sufficient amount of plasma concentration data from this study, the data will be 
analyzed by standard population PK methods using appropriate software (eg, NONMEM).

Analyses for the Data Monitoring Committee 
Preplanned analyses of safety will be provided to the iDSMB at regular intervals throughout the 
study as specified in the iDSMB charter. 
9.6. 
Interim Analysis 
In Part 4, a stopping rule for futility is planned for each combination dose expansion treatment 
group.  The futility analyses for combination TGs will be conducted when 15 subjects for each 
disease type have been treated and evaluated for response or have permanently discontinued 
study treatment because of disease progression, withdrawal of consent, or death.  The futility

analyses for TG D1 will be conducted when the first 15 subjects with AML or when the first 
15 subjects with MDS have been treated.  Combination TG C1 will be terminated for futility if 
≤ 1 of the 15 subjects responded (ie, CR, CRi, MLFS) based on assessments provided by 
investigator.  Combination TG D1 will terminate enrollment for subjects with AML if ≤ 2 of the 
first 15 AML subjects responded (ie, CR, CRi, MLFS) or will terminate enrollment for subjects 
with MDS if ≤ 2 of the first 15 MDS subjects responded (ie, CR or marrow CR), based on 
assessments provided by investigator.  Combination TG E1 will be terminated for futility if 
≤ 1 of the 15 subjects responded (ie, CR or PR) based on assessments provided by investigator. 
10. 
ETHICAL CONSIDERATIONS AND ADMINISTRATIVE 
PROCEDURES 
10.1. 
Investigator Responsibilities 
This study will be performed in accordance with ethical principles that originate in the 
Declaration of Helsinki and conducted in adherence to the study Protocol; GCPs as defined in 
Title 21 of the US CFR Parts 11, 50, 54, 56, and 312; ICH E6 GCP consolidated guidelines; and 
local regulatory requirements as applicable to the study locations. 
The investigator will be responsible for: 
• Permitting study-related monitoring, sponsor audits, IRB/IEC review, and regulatory 
inspections by providing direct access to source data and other relevant clinical study 
documents. 
− Monitoring:  Qualified representatives of the sponsor or its designee, study 
monitors, will monitor the study according to a predetermined plan.  The 
investigator must allow the study monitors to review any study materials and 
subject records at each monitoring visit. 
− Auditing:  Qualified representatives of the sponsor or its designee may audit the 
clinical study site and study data to evaluate compliance with the Protocol, 
applicable local clinical study regulations, and overall study conduct.  The 
investigator must allow the auditors to review original source records and study 
documentation for all subjects. 
− Regulatory inspection:  Regulatory authorities may conduct an inspection of the 
study and the site at any time during the development of an investigational 
product.  The investigator and staff are expected to cooperate with the inspectors 
and allow access to all source documents supporting the eCRFs and other 
study-related documents.  The investigator must immediately notify the sponsor 
when contacted by any regulatory authority for the purposes of conducting an 
inspection. 
• Obtaining informed consent and ensuring that the study subjects' questions have been 
answered and the subjects fully understand study procedures: 
− Informed consent must be obtained before any study-related procedures are 
conducted, unless otherwise specified by the Protocol. 

Incyte Corporation 
Page 85 of 124 
Protocol INCB 59872-101 Am 8 
Version 8 
15 JUN 2020 
CONFIDENTIAL 
− Informed consent must be obtained using the IRB/IEC-approved version in a 
language that is native and understandable to the subject.  A template will be 
provided by the sponsor or its designee.  The sponsor or its designee must review 
and acknowledge the site-specific changes to the ICF template.  The ICF must 
include a statement that the sponsor or its designee and regulatory authorities have 
direct access to subject records. 
• Obtaining approval from the IRB/IEC before the start of the study and for any 
changes to the clinical study Protocol, important Protocol deviations, routine updates, 
and safety information in accordance with institutional requirements and local law. 
− The investigator is responsible for ensuring that the safety reports provided by the 
sponsor are reviewed and processed in accordance with regulatory requirements 
and with the policies and procedures established by the IRB/IEC. 
• Adhering to the Protocol as described in this document and agreeing that changes to 
the Protocol procedures, with the exception of medical emergencies, must be 
discussed and approved, first, by the sponsor or its designee and, second, by the 
IRB/IEC.  Each investigator is responsible for enrolling subjects who have met the 
specified eligibility criteria. 
• Retaining records in accordance with all local, national, and regulatory laws, but for a 
minimum period of at least 2 years after the last marketing application approval in an 
ICH region and until there are no pending or contemplated marketing applications in 
an ICH region, or if not approved, 2 years after the termination of the test article for 
investigation to ensure the availability of study documentation should it become 
necessary for the sponsor or a regulatory authority to review. 
− The investigator must not destroy any records associated with the study without 
receiving approval from the sponsor.  The investigator must notify the sponsor or 
its designee in the event of accidental loss or destruction of any study records.  If 
the investigator leaves the institution where the study was conducted, the sponsor 
or its designee must be contacted to arrange alternative record storage options. 
− All eCRF data entered by the site (including audit trail), as well as computer 
hardware and software (for accessing the data), will be maintained or made 
available at the site in compliance with applicable record retention regulations.  
The sponsor will retain the original eCRF data and audit trail. 
10.2. 
Accountability, Handling, and Disposal of Study Drug 
The investigator is responsible for drug accountability at the study site; however, some of the 
drug accountability duties may be assigned to an appropriate pharmacist or other designee.  
Inventory and accountability records must be maintained and readily available for inspection by 
the study monitor and are open to inspection at any time by any applicable regulatory authorities.  
The investigator or designee must maintain records that document: 
• Delivery of study drug to the study site. 
• Inventory of study drug at the site. 

Incyte Corporation 
Page 86 of 124 
Protocol INCB 59872-101 Am 8 
Version 8 
15 JUN 2020 
CONFIDENTIAL 
• Subject use of the study drug including pill or unit counts from each supply 
dispensed. 
• Return of study drug to the investigator or designee by subjects. 
The investigational product must be used only in accordance with the Protocol.  The investigator 
will also maintain records adequately documenting that the subjects were provided the specified 
study drug.  These records should include dates, quantities, and any available batch or serial 
numbers or unique code numbers assigned to the investigational product and study subjects. 
Completed accountability records will be archived by the site.  The investigator or designee will 
be expected to collect and retain all used, unused, and partially used containers of study drug 
until verified by the study monitor (unless otherwise agreed to by the sponsor).  At the 
conclusion of the study, the investigator or designee will oversee shipment of any remaining 
study drug back to the sponsor or its designee for destruction according to institutional standard 
operating procedures.  If local procedures mandate on-site destruction of investigational supply, 
the site should (where local procedures allow) maintain the investigational supply until the study 
monitor inspects the accountability records in order to evaluate compliance and accuracy of 
accountability by the investigative site.  At sites where the study drug is destroyed before 
monitor inspection, the monitors rely on documentation of destruction per the site SOP. 
10.3. 
Data Management 
Data management will be performed in a validated database via an Electronic Data Capture 
(EDC) system.  All data entry, verification, and validation will be performed in accordance with 
the current standard operating procedures of the Data Management Department at the sponsor or 
its designee.  The database will be authorized for lock once all defined procedures are completed. 
The investigator will be provided with access to an EDC system so that an eCRF can be 
completed for each subject.  Entries made in the eCRF must be verifiable against source 
documents; if updates to the database are not possible, any discrepancies should be explained 
and documented.  The investigator will be responsible for reviewing all data and eCRF entries, 
and will sign and date the designated forms in each subject's eCRF, verifying that the 
information is true and correct.  The investigator is responsible for the review and approval of all 
query responses. 
Protocol deviations will be identified and recorded in the Protocol Deviation form of the eCRF.  
The study monitor will reference the Monitoring Plan in order to ensure that each issue identified 
is appropriately documented, reported, and resolved in a timely manner in accordance with the 
plan's requirements. 
10.4. 
Data Privacy and Confidentiality of Study Records 
The investigator and the sponsor or its designee must adhere to applicable data privacy laws and 
regulations.  The investigator and the sponsor or its designee are responsible for ensuring that 
sensitive information is handled in accordance with local requirements (eg, HIPAA).  
Appropriate consent and authorizations for use and disclosure and/or transfer (if applicable) of 
protected information must be obtained.

CONFIDENTIAL 
Subject names will not be supplied to the sponsor or its designee, if applicable.  Only the subject 
number and subject's initials (subject's initials will only be recorded if allowable by local 
regulations) will be recorded in the eCRF, where permitted; if the subject's name appears on any 
other document (eg, laboratory report), it must be obliterated on the copy of the document to be 
supplied to the sponsor or its designee.  Study findings stored on a computer will be stored in 
accordance with local data protection laws.  The subjects will be informed that representatives of 
the sponsor or its designee, IRB or IEC, or regulatory authorities may inspect their medical 
records to verify the information collected, and that all personal information made available for 
inspection will be handled in strictest confidence and in accordance with local data protection 
laws. 
10.5. 
Financial Disclosure 
Before study initiation, all clinical investigators participating in clinical studies subject to FDA 
Regulation Title 21 CFR Part 54 – Financial Disclosure by Clinical Investigators (ie, "covered 
studies") are required to submit a completed Clinical Investigator Financial Disclosure form that 
sufficiently details any financial interests and arrangements that apply.  For the purpose of this 
regulation, "clinical investigator" is defined as any investigator or subinvestigator who is directly 
involved in the treatment or evaluation of research subjects, including the spouse and each 
dependent child of the clinical investigator or subinvestigator.  These requirements apply to both 
US and foreign clinical investigators conducting covered clinical studies. 
Any new clinical investigators added to the covered clinical study during its conduct must also 
submit a completed Investigator Financial Disclosure Form.  During a covered clinical study, 
any changes to the financial information previously reported by a clinical investigator must be 
reported to the sponsor or its designee.  At the conclusion of the covered clinical study, the 
clinical investigators will be reminded of their obligations.  In the event that the clinical 
investigator is not reminded, they nevertheless will remain obligated to report to the sponsor or 
its designee any changes to the financial information previously reported, as well as any changes 
in their financial information for a period of 1 year after completion of the covered clinical study. 
10.6. 
Publication Policy 
By signing the study Protocol, the investigator and his or her institution agree that the results of 
the study may be used by the sponsor, Incyte Corporation (Incyte), for the purposes of national 
and international registration, publication, and information for medical and pharmaceutical 
professionals.  Study results will be published in accordance with applicable local and national 
regulations.  If necessary, the authorities will be notified of the investigator's name, address, 
qualifications, and extent of involvement.  The terms regarding the publication of study results 
are contained in the agreement signed with the sponsor or its designee.  A signed agreement will 
be retained by the sponsor or its designee.

APPENDIX A. INFORMATION REGARDING EFFECTIVENESS OF 
CONTRACEPTIVE METHODS 
For Subjects Participating in the Study: 
The following methods that can achieve a failure rate of less than 1% per year when used 
consistently and correctly are considered as highly effective birth control methods.  
Such methods include: 
• Combined (estrogen and progestogen containing) hormonal contraception associated 
with inhibition of ovulation1 
− oral 
− intravaginal 
− transdermal 
• Progestogen-only hormonal contraception associated with inhibition of ovulation1 
− oral 
− injectable 
− implantable2 
• Intrauterine device (IUD)2 
• Intrauterine hormone-releasing system (IUS)2 
• Bilateral tubal occlusion2 
• Vasectomised partner2,3 
• Sexual abstinence4 
 
1  Hormonal contraception may be susceptible to interaction with the IMP, which may reduce the efficacy of the 
contraception method. 
2  Contraception methods that in the context of this guidance are considered to have low user dependency. 
3  Vasectomised partner is a highly effective method provided of avoiding pregnancy that partner is the sole sexual 
partner of the WOCBP trial participant and that the vasectomised partner has received medical assessment of the 
surgical success.  
4  In the context of this guidance, sexual abstinence is considered a highly effective method only if defined as 
refraining from heterosexual intercourse during the entire period of risk associated with the study treatments.  The 
reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the 
preferred and usual lifestyle of the subject.

APPENDIX D. INTERNATIONAL WORKING GROUP RESPONSE 
CRITERIA FOR ACUTE MYELOID LEUKEMIA 
Response Category 
Response Definition 
Complete remission (CR)1 
Bone marrow blasts < 5 percent; absence of blasts with Auer rods; 
absence of extramedullary disease; absolute neutrophil count 
> 1.0 × 109/L (1000/μL); platelet count > 100 × 109/L (100,000/μL); 
independence of red cell transfusions 
CR with incomplete recovery 
(CRi) 
All CR criteria except for residual neutropenia (< 1.0 × 109/L [1000/μL]) 
or thrombocytopenia (< 100 × 109/L [100,000/µL]) 
Morphologic leukemia-free 
state 
Bone marrow blasts < 5 percent; absence of blasts with Auer rods; 
absence of extramedullary disease; no hematologic recovery required 
Partial remission (PR) 
All hematologic criteria of CR; decrease of bone marrow blast 
percentage to 5 to 25 percent; and decrease of pretreatment bone marrow 
blast percentage by at least 50 percent 
Cytogenetic CR (CRC) 
Reversion to a normal karyotype at the time of morphologic CR (or CRi) 
in cases with an abnormal karyotype at the time of diagnosis; based on 
the evaluation of 20 metaphase cells from bone marrow 
Molecular CR (CRm) 
No standard definition; depends on molecular target 
Treatment failure 
Resistant disease (RD) 
Failure to achieve CR or Cri or PR (Phase 1 trials); only includes patients 
surviving ≥ 7 days following completion of initial treatment, with 
evidence of persistent leukemia by blood and/or bone marrow 
examination 
Death in aplasia 
Deaths occurring ≥ 7 days following completion of initial treatment 
while cytopenic; with an aplastic or hypoplastic bone marrow obtained 
within 7 days of death, without evidence of persistent leukemia 
Death from indeterminate 
cause 
Deaths occurring before completion of therapy, or < 7 days following its 
completion; or deaths occurring ≥ 7 days following completion of initial 
therapy with no blasts in the blood, but no bone marrow examination 
available 
Relapse2 
Bone marrow blasts ≥ 5 percent; or reappearance of blasts in the blood; 
or development of extramedullary disease 
1 All criteria need to be fulfilled; marrow evaluation should be based on a count of 200 nucleated cells in an aspirate 
with spicules; if ambiguous, consider repeat exam after 5 to 7 days; flow cytometric evaluation may help to 
distinguish between persistent leukemia and regenerating normal marrow; a marrow biopsy should be performed 
in cases of dry tap, or if no spicules are obtained; no minimum duration of response required. 
2 In cases with low blast percentages (5 to 10 percent), a repeat marrow should be performed to confirm relapse.  
Appearance of new dysplastic changes should be closely monitored for emerging relapse.  In a patient who has 
been recently treated, dysplasia or a transient increase in blasts may reflect a chemotherapy effect and recovery of 
hematopoiesis. Cytogenetics should be tested to distinguish true relapse from therapy-related MDS/AML.

≥ 1 × 109/L and < UNL; platelet count ≥ 50, but < 100 × 109/L and < UNL; < 2% immature 
myeloid cells‡ 
• Resolution of disease symptoms; spleen and liver not palpable; no evidence of EMH 
Clinical 
improvement 
• The achievement of anemia, spleen or symptoms response without progressive disease or 
increase in severity of anemia, thrombocytopenia, or neutropenia§ 
Anemia response  
• Transfusion-independent patients:  a ≥ 20 g/L increase in hemoglobin level|| 
• Transfusion-dependent patients:  becoming transfusion-independent¶ 
Spleen response 
• Baseline splenomegaly that is palpable at 5-10 cm, below the LCM, becomes not 
palpable** or 
• Baseline splenomegaly that is palpable at > 10 cm, below the LCM, decreases by ≥ 50%** 
- 
Baseline splenomegaly that is palpable at < 5 cm, below the LCM, is not eligible for 
spleen response 
- 
Spleen response requires confirmation by MRI or computed tomography showing 
≥ 35% spleen volume reduction. 
Progressive 
disease‡‡ 
• Appearance of a new splenomegaly that is palpable at least 5 cm below the LCM or 
• ≥ 100% increase in palpable distance, below LCM, for baseline splenomegaly of 5-10 cm 
or 
• 50% increase in palpable distance, below LCM, for baseline splenomegaly of > 10 cm or 
• Leukemic transformation confirmed by a bone marrow blast count of ≥ 20% or 
• Peripheral blood blast content of ≥ 20% associated with an absolute blast count of 
≥ 1 × 109/L that lasts for at least 2 weeks 
Stable disease 
• Belonging to none of the above listed response categories. 
Relapse 
• No longer meeting criteria for at least CI after achieving CR, PR, or CI, or 
• Loss of anemia response persisting for at least 1 month, or 
• Loss of spleen response persisting for at least 1 month. 
See above for definitions of anemia response, spleen response, and progressive disease.  Increase in severity of anemia 
constitutes the occurrence of new transfusion dependency or a ≥ 20 g/L decrease in hemoglobin level from pretreatment 
baseline that lasts for at least 12 weeks.  Increase in severity of thrombocytopenia or neutropenia is defined as a 2-grade 
decline, from pretreatment baseline, in platelet count or absolute neutrophil count, according to the Common Terminology 
Criteria for Adverse Events (CTCAE) version 4.0.  In addition, assignment to CI requires a minimum platelet count of 
≥ 25,000 × 109/L and absolute neutrophil count of ≥ 0.5 × 109/L.

|| Applicable only to patients with baseline hemoglobin of < 100 g/L.  In patients not meeting the strict criteria for transfusion 
dependency at the time of study enrollment (see as follows), but who have received transfusions within the previous month, the 
pretransfusion hemoglobin level should be used as the baseline. 
¶ Transfusion dependency before study enrollment is defined as transfusions of at least 6 units of packed red blood cells (PRBC), 
in the 12 weeks before study enrollment, for a hemoglobin level of < 85 g/L, in the absence of bleeding or treatment-induced 
anemia.  In addition, the most recent transfusion episode must have occurred in the 28 days before study enrollment.  Response 
in transfusion-dependent patients requires absence of any PRBC transfusions during any consecutive "rolling" 12-week interval 
during the treatment phase, capped by a hemoglobin level of ≥ 85 g/L. 
# In splenectomized patients, palpable hepatomegaly is substituted with the same measurement strategy. 
** Spleen or liver responses must be confirmed by imaging studies where a ≥ 35% reduction in spleen volume, as assessed by 
MRI or CT, is required.  Furthermore, a ≥ 35% volume reduction in the spleen or liver, by MRI or CT, constitutes a response 
regardless of what is reported with physical examination. 
‡‡ Progressive disease assignment for splenomegaly requires confirmation by MRI or computed tomography showing a ≥ 25% 
increase in spleen volume from baseline.  Baseline values for both physical examination and imaging studies refer to 
pretreatment baseline and not to posttreatment measurements.

Supportive Care 
Endocrinopathies 
Note:  Subjects should be monitored for clinical signs and symptoms of 
hypophysitis, adrenal insufficiency (including adrenal crisis), and hyper- or 
hypothyroidism.  Subjects may present with fatigue, headache, mental status 
changes, abdominal pain, unusual bowel habits, and hypotension, or nonspecific 
symptoms which may resemble other causes such as brain metastasis or underlying 
disease.  Unless an alternate etiology has been identified, signs or symptoms of 
endocrinopathies should be considered immune-mediated. 
For Grade 2 (mild to moderate new symptoms):  
• 
In hypophysitis, treat with systemic corticosteroids, per institutional standard 
of care.  When symptoms improve to Grade 1 or less, steroid taper should be 
started and continued over no less than 4 weeks.  Replacement of appropriate 
hormones may be required as the steroid dose is tapered. 
Note: These suggested supportive care measures also apply to Grade 3 
hypophysitis  
• 
In hyperthyroidism, nonselective beta-blockers (eg, propranolol) are suggested 
as initial therapy. 
• 
In hypothyroidism, thyroid hormone replacement therapy, with levothyroxine 
or liothyronine, is indicated per standard of care. 
Note: Isolated hypothyroidism may be treated with replacement therapy 
without treatment interruption and without corticosteroids. 
• 
Evaluate endocrine function and, as clinically indicated, consider pituitary 
scan. 
• 
For subjects with abnormal endocrine work-up, except for those with isolated 
hypothyroidism, consider short-term, high-dose corticosteroids (eg, 
methylprednisolone or IV equivalent) and initiate appropriate hormone 
replacement therapy. 
• 
For subjects with normal endocrine work-up (labs or MRI), repeat labs/MRI as 
clinically indicated. 
For Grade 3 or 4 (severe or new symptoms, new/worsening endocrinopathies, 
life-threatening): 
• 
Hypothyroidism may be treated with replacement therapy without treatment 
interruption and without corticosteroids. 
• 
In hyperthyroidism, treat with an initial dose of IV corticosteroid followed by 
oral corticosteroids.  Consider initiation of systemic corticosteroids at a dose of 
1-2 mg/kg per day of prednisone or equivalent, and initiate appropriate 
hormone replacement therapy.  Once improving, gradually taper 
immunosuppressive steroids over ≥ 4 weeks. 
• 
In hypophysitis, treat with an initial dose of IV corticosteroids followed by oral 
corticosteroids.  When symptoms improve to Grade 1 or less, steroid taper 
should be started and continued over no less than 4 weeks.  Replacement of 
appropriate hormones may be required as the steroid dose is tapered. 
• 
For adrenal crisis, severe dehydration, hypotension, or shock:  immediately 
initiate intravenous corticosteroids with mineralocorticoid activity. 
• 
Consult endocrinologist. 
• 
Consult medical monitor.

Note:  Monitor subjects for symptoms of motor or sensory neuropathy such as 
unilateral or bilateral weakness, sensory alterations, or paresthesia. 
For Grade 2 (mild to moderate new symptoms):  
• 
Consider systemic corticosteroids per institutional standard of care in addition 
to appropriate symptomatic treatment. 
• 
If no improvement within 3-5 days, consider additional work-up and consider 
treating with additional immunosuppressive therapy (eg, IV IgG), after 
discussing with the medical monitor. 
For Grade 3 or 4 (severe or new symptoms, new/worsening neuropathies, 
life-threatening): 
• 
Consider initiation of systemic corticosteroids (IV administration should be 
strongly considered) for severe neuropathies. 
• 
Institute medical intervention as appropriate for management of severe 
neuropathy. 
• 
If no improvement within 3-5 days despite IV corticosteroids, consider 
additional workup and consider treating with additional immunosuppressants 
(eg, IV IgG) after discussing with the medical monitor. 
• 
Once stable, gradually taper steroids over ≥ 4 weeks.
