ABSTRACT & SCHEMA 
This is a multicenter phase 1 trial of INCB007839 for children with recurrent or progressive high-
grade gliomas, including but not limited to diffuse intrinsic pontine glioma (DIPG) and other 
diffuse midline gliomas (DMGs), after upfront therapy.  
 
INCB007839 is an inhibitor of the ADAM (A Disintegrin and Metalloprotease) 10 and 17 
proteases. Neuronal activity regulates glioma growth through neuroligin-3 (NLGN3). ADAM10 
is the protease responsible for NLGN3 release into the tumor microenvironment and represents a 
promising therapeutic target. Pre-clinical studies of INCB007839 in patient-derived pediatric high-
grade gliomas (glioblastoma and DIPG) revealed that INCB007839 inhibits pediatric high-grade 
glioma growth and improves overall survival. In vivo testing also demonstrated that INCB007839 
penetrates brain tissue sufficient to achieve its pharmacodynamic effect of ADAM10 inhibition. 
Further pre-clinical studies in other animals revealed minimal toxicity, including non-adverse to 
mild increases in serum hepatobiliary enzymes, protein, calcium, cholesterol values, along with 
minimal decreases in RBC mass parameters; all parameters recovered. 
 
INCB007839 has been evaluated in phase 1 and phase 2 clinical trials for previously treated solid 
tumors and breast cancer. Of the adverse events noted, the majority were mild-to-moderate in 
severity, the most frequent being fatigue, nausea, anorexia, diarrhea, emesis, abdominal pain, 
anemia, and constipation. The dose-limiting toxicity for monotherapy with INCB007839 in phase 
1 clinical trials was declared to be deep venous thrombosis (DVT). Out of 41 patients, there were 
9 thrombotic events including mild superficial thrombophlebitis (n=1), DVT (n=4), vena cava 
thrombosis with renal insufficiency in a patient with squamous cell cancer of the head and neck 
(n=1), atrial thrombosis in patient with breast cancer (n=1), and pulmonary embolism in patients 
with hormone-refractory prostate cancer (n=2). Overall, INCB007839 does exhibit a pro-coagulant 
effect in some adult patients, resulting in an increased incidence of DVT, whether used alone or in 
combination. The mechanism of this effect is unknown, and there is no clear relationship between 
the frequency of thrombosis and the dose administered.  
 
The primary objectives of this study are to: (1) evaluate the safety and tolerability of INCB007839 
administered daily to children with recurrent/progressive high-grade gliomas; (2) determine the 
maximum tolerated dose (MTD) and/or recommended phase 2 (RP2D) dose of INCB007839; and 
(3) characterize the pharmacokinetics of INCB007839.  
 
The adult RP2D is 200 mg orally (PO) twice a day (BID). Given this recommended dose, we 
propose to test the pediatric equivalent based on a typical adult size of 1.67 m2. Thus, this clinical 
trial will start at 120 mg/m2 and de-escalate to 80 mg/m2 if not tolerable. INCB007839 will be 
administered orally, twice a day each day for 28-day cycles. Treatment may continue up to 26 
courses (approximately 2 years) in the absence of disease progression or unacceptable toxicity.

BACKGROUND 
 
2.1 
Study Disease 
 
2.1.1 Pediatric Recurrent/Progressive High-Grade Glioma 
Childhood brain tumors are the most common solid malignancy and the leading cause of cancer-
related mortality in children.1 The most aggressive type of pediatric central nervous system (CNS) 
tumors is high-grade glioma, including diffuse intrinsic pontine glioma (DIPG). Surgical resection, 
where possible, and radiotherapy may prolong survival, but at the time of recurrence or progression 
there are no effective treatments. Despite decades of clinical trials, there has been no substantial 
improvement with respect to therapeutic outcomes and most children eventually succumb to the 
disease.2  
 
Therapies aimed at targetable pathways and mechanisms intrinsic to the glioma cell have translated 
to only limited success. Recent research shows that neuronal activity robustly promotes the growth 
of a range of molecularly and clinically distinct high-grade glioma (HGG) types, including adult 
glioblastoma (GBM), anaplastic oligodendroglioma, pediatric GBM, and DIPG.3 A key 
mechanism of neuronal activity-regulated glioma growth is activity-regulated cleavage and release 
of the postsynaptic adhesion molecule Neuroligin-3 (NLGN3). ADAM (A Disintegrin and 
Metalloprotease) 10 is the protease responsible for neuronal activity-regulated neuroligin-3 
cleavage and secretion into the glioma microenvironment. In this clinical trial, the use of an 
ADAM10 inhibitor is a therapeutic strategy to target elements of the tumor microenvironment that 
promote glioma progression.3 The poor prognosis of high-grade gliomas in children, combined 
with the lack of effective therapies, emphasizes the importance of targeting this key 
microenvironmental mechanism promoting glioma growth.  
 
2.1.2 Overview of neuronal activity and its role in glioma growth 
Active neurons exert a robust mitogenic effect on normal neural precursor cells (NPCs) and 
oligodendrocyte progenitor cells (OPCs) in the juvenile and adult mammalian brain.4 With this 
knowledge, it was hypothesized that neuronal activity may similarly promote the proliferation of 
HGG cells. Using optogenetic control of neuronal activity in patient-derived HGG models, it was 
demonstrated that neuronal activity does indeed promote circuit-specific HGG proliferation and 
growth.3 To determine molecular mechanisms mediating the observed activity-regulated glioma 
growth, conditioned medium was examined from acute brain slices that were optogenetically 
stimulated, tetrodotoxin-silenced, or exhibited spontaneous neuronal activity. It was found that 
activity-regulated glioma mitogens were secreted into the conditioned media. Biochemical and 
proteomic analyses of this conditioned medium followed by sufficiency and necessity testing of 
the candidate factors identified brain-derived neurotrophic factor (BDNF), and unexpectedly, a 
secreted form of the synaptic protein neuroligin-3 (NLGN3) as the key mechanisms mediating 
activity-dependent glioma growth (Figure 1A). It was then determined that NLGN3 is cleaved in 
activity regulated fashion by the ADAM10 sheddase at the transmembrane domain, releasing the 
large N-terminal ectodomain (Figure 2). After binding to glioma cells via an as-of-yet unidentified 
binding partner that is currently being worked on, NLGN3 stimulated focal adhesion kinase (FAK) 
and downstream PI3K-mTOR pathway (Figure 1A), as well as numerous additional signaling and 
gene expression consequences. Among the gene expression changes that were observed following 
NLGN3 exposure is a feed-forward expression of NLGN3 itself in the glioma cell, together with 

NCI Protocol #: PBTC-056

10 
numerous other genes associated with synapse component.3,5 Furthermore, it was observed that 
activity-regulated glioma proliferation and growth response to NLGN3 is a conserved mechanism 
across clinically and molecularly-distinct glioma types, including adult GBM, adult anaplastic 
oligodendroglioma, pediatric GBM and DIPG3. These findings indicated, for the first time, the 
important role of active neurons in the brain tumor microenvironment.  
 
To test just how necessary NLGN3 is to HGG progression, patient-derived HGG were xenografted 
into NLGN3 knockout mice (back-bred onto an immunodeficient NOD-SCID-IL2R-gamma 
chain-deficient (NSG) strain to enable xenografting). It was found that HGG growth is strikingly 
and unexpectedly dependent on neuroligin-3 in the brain microenvironment. Xenografts of patient-
derived pediatric GBM, DIPG, and adult GBM engraft, but fail to grow in brains lacking 
neuroligin-3 for up to six months (Figure 1B–C.)5 Around six months, a subset of xenografts begin 
to grow through mechanisms that are currently being worked on. The requirement for neuoligin-3 
in the microenvironment is conserved across glioma types, but does not extend to all cancers, as 
patient-derived breast cancer metastases grow well in the neuroligin-3 knockout brain.5

2.1.3 Overview of ADAM10 inhibition in pediatric high-grade gliomas 
The inhibition of glioma growth observed in the neuroligin-3 deficient tumor highlights the 
potential to target this dependency for therapy. Having determined that ADAM10 is the enzyme 
responsible for activity-regulated NLGN3 cleavage and release into the glioma microenvironment 
(Figure 2), ADAM10 inhibition was tested as a therapeutic potential with the specific ADAM10 
inhibitor GI254023X and found dramatic growth inhibition in a range of patient-derived HGG 
xenograft models (Figure 2f-i).5 Due to the fact that GI254023X is not available for clinical use, 
blood brain barrier (BBB) penetration was then tested using INCB007839 (brand name 
Aderbasib), an ADAM 10/17 inhibitor that has progressed through a phase 1/2 clinical trial 
(NCT01254136) for breast cancer. Through these experiments, it was found that INCB007839 
penetrates brain tissue to a reasonable degree, achieving > 100 ng/ml (~240 nM) concentration for 
~4 hours.5 Accordingly, proof-of-principal in vivo testing of INCB007839 in a patient-derived 
orthotopic xenograft model of pediatric GBM demonstrates robust growth inhibition (Figure 3a–
d).5

Investigational Agent: INCB007839 (Aderbasib™) 
 
2.2.1 Preclinical Studies 
 
2.2.1.1 Anti-tumor activity 
INCB007839 is a selective inhibitor of the enzyme activity of the ADAM family of zinc-dependent 
metalloproteases, specifically ADAM 10/ADAM 17. INCB007839 was originally studied in breast 
cancer as ADAM metalloproteinases (also referred as sheddases) affect ErbB signaling.6 The ErbB 
family of receptor tyrosine kinases (RTKs) is composed of EGFR (HER1 or ErbB1), HER2 (neu 
or ErbB2), HER3 (ErbB3), and HER4 (ErbB4).7-9 Several ligands, including epidermal growth 
factor (EGF), transforming growth factor α (TGF-α), and four heregulin (HRG)/neuregulin (NRG) 
family members to name a few, bind to the ErbB family of RTKs. This ligand binding has been 
shown to lead to receptor dimerization, receptor phosphorylation, and subsequent activation of 
multiple downstream signaling cascades, including Ras/MAPK, PI3K/Akt and STATs that are 
essential for promoting cell growth, survival, and resistance to apoptosis. Dysregulation of this 
ErbB signaling pathways has been observed in numerous solid tumors, including breast, gastric, 
colon, non-small cell lung cancer, and prostate. ADAM inhibition restores this regulation. 
Xenograft studies in breast cancer and other solid tumors suggest that INCB007839 treatment, as 
a monotherapy, results in tumor growth inhibition. Furthermore, tumor growth inhibition was 
shown to coincide with significant reductions in cell proliferation in breast cancer cell lines.  
 
The preclinical data described in the pediatric glioma section above is the only pediatric data 
described in the literature using INCB007839. Due to the finding that ADAM10 mediates activity-
regulated NLGN3 secretion into the tumor microenvironment, INCB007839 was used to alter 
NLGN3 release in pediatric brain high-grade gliomas. Figure 3 shows INCB007839 inhibiting 
growth in pediatric high-grade gliomas (patient-derived orthotopic xenograft models of DIPG and 
pGBM).

2.2.1.2 Animal Toxicity 
In toxicokinetic studies of INCB007839, INCB007839-related microscopic changes were noted in 
spleen, liver, bile duct, and thymus at the higher doses, all of which recovered following cessation 
of drug. Inhibition of long bone growth was observed with genetic ADAM10 deletion in mice. 10 
 
2.2.1.3 Preclinical Pharmacology 
The pharmacokinetics of INCB007839 following intravenous (IV) and oral doses have been 
determined in mice, rats, beagle dogs, cynomolgus monkeys, and chimpanzees. Across species, 
INCB007839 exhibited an elimination half-life ranging from 1.6 hours in mice to 6.7 hours in 
chimpanzees after oral doses. In all species, oral INCB007839 was rapidly absorbed with a time 
to reach maximum concentration observed between 0.1 and 2 hours. The average bioavailability 
was determined at 51%, 18%, and 30% in rats, dogs, and chimpanzees, respectively. The CNS 
distribution of INCB007839 was determined in rats after an IV bolus dose of 1 mg/kg followed by 
a 2 mg/kg/hour IV infusion for 4 hours. The total brain to plasma partition coefficient (Kp) was 
0.17 ± 0.23. INCB007839 was not highly protein bound with free fractions in mouse, rat, dog, and 
cynomolgus monkey determined at 10 µM to be 36%, 41%, 79%, and 55%, respectively. 
INCB007839 is not a potent inhibitor of CYP3A4. There was no significant metabolism of 
INCB007839 by any of the five major P450 (CYP) isozymes, and therefore the pharmacokinetic 
profile is not expected to be significantly affected by drugs that inhibit or induce CYP450 
isoenzymes.  
 
2.2.2 Adult Clinical Trials 
 
2.2.2.1 Healthy Volunteer Studies 
Four single and multiple-dose studies have been completed with INCB007839 in 112 healthy 
volunteers (INCB 7839-101, -102, -105, -120). In these studies, adverse events (AEs) were mild 
and self-limited, and included headache, diarrhea, abdominal cramps, maculopapular rash, 
somnolence, flushing, Grade 2 elevation of alanine aminotransferase, and upper respiratory tract 
infections. One subject experienced a serious adverse event (SAE) of DVT that was considered 
possibly related to study medication; this subject was subsequently found to have antithrombin III 
deficiency.

2.2.2.2 Phase 1 Study using INCB007839 as Monotherapy 
In study INCB 7839-201 (also identified as NCT00820560), an open-label dose escalation study 
that enrolled 41 patients with advanced, previously treated solid tumors (including colorectal 
cancer, hormone refractory prostate cancer, breast cancer, or cancer of the head-and-neck), doses 
between 100 mg (immediate release, IR) twice a day (BID), and up to 500 mg (sustained release, 
SR) BID were explored. Of the AEs judged at least possibly related to study drug, the majority 
were mild-to-moderate in severity, the most frequent being fatigue, nausea, anorexia, diarrhea, 
emesis, abdominal pain, anemia, and constipation. The dose-limiting toxicity was declared to be 
DVT, although a clear dose-related relationship was not evident. There was a total of 9 thrombotic 
events occurring during the study including mild superficial thrombophlebitis (n=1, at dose of 300 
mg SR BID plus warfarin prophylaxis), DVT (n=4, at dose of 300 mg SR BID), vena cava 
thrombosis with renal insufficiency in a patient with squamous cell cancer of the head and neck 
(n=1, at dose of 100 mg SR BID), atrial thrombosis in patient with breast cancer (n=1, at dose of 
300 mg SR BID), and pulmonary embolism in patients with hormone-refractory prostate cancer 
(n=2, one subject at dose 200 mg SR BID and other subject at 500 mg SR BID plus warfarin 
prophylaxis). Several patients had complicating factors, such as the presence of advanced disease. 
The study was amended to include low dose warfarin as the primary component for thrombosis 
prophylaxis. Among 16 subjects taking either warfarin, aspirin, or both, two thrombotic events 
occurred (one patient developed superficial thrombophlebitis and one experienced a pulmonary 
embolism). In this study, there is no clear relationship between thrombosis events and the dose 
administered. Formal efficacy analysis was not conducted in this trial.  
 
2.2.2.3 Phase 1/2 Studies using INCB007839 in Combination Therapy 
Study INCB007839-202 (also identified as NCT00864175) is a phase 1/2 study using 
INCB007839 + trastuzumab + docetaxel (added at cycle 3 or later) for patients with previously 
untreated metastatic HER2+ breast cancer. The most frequently reported events occurring in 
≥ 10% of patients were emesis, pyrexia, anorexia, pain, diarrhea, dyspnea, asthenia, headache, 
cough, arthralgia, vascular events, abdominal pain, and back pain; the majority of these events 
were not serious. Warfarin, as well as low dose aspirin in some patients, was used for thrombosis 
prophylaxis. The overall event rate of thrombosis in the study so far is 10% (7 of 65 patients 
reported); similar, if not less than the estimated rate of 10–17% in women with metastatic breast 
cancer receiving multi-drug therapy.11,12 Efficacy data has not been reported.  
 
Study INCB007839-204 (also identified as NCT01254136) is a phase 1/2 study using 
INCB007839 + trastuzumab + vinorelbine in patients with metastatic HER2+ breast cancer. 
Emerging data suggests the regimen is tolerable, however, further data is not available.  
 
Cumulatively, these data suggest that INCB007839 has an adverse event profile consistent with 
the adult metastatic cancer study population. INCB007839 appears to exhibit a pro-coagulant 
effect in some adult patients, as evidenced by a potential increase in DVT incidence, whether used 
alone or in combination with trastuzumab. The mechanism of this effect is unknown.  
 
2.2.2.4 Clinical Pharmacokinetics 
INCB007839 pharmacokinetics was evaluated in healthy volunteers receiving the drug orally as 
immediate release (IR) tablets or as sustained release (SR) tablets. Following fasting 
administration of the INCB007839 IR tablets, the drug was rapidly absorbed with a time to reach 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
16 
maximum concentration within 1 to 2 hours post-administration. The plasma INCB007839 
concentrations were decreasing in a biphasic manner with a terminal half -life of approximately 
10–14 hours. Following fasting administration of the INCB007839 SR tablets, the drug was 
absorbed more slowly with a time to reach maximum concentration shifting to 2 to 4 hours post-
administration. Between the single dose range of 50 to 600 mg and the multiple doses range of 50 
to 200 mg twice of day in adults, INCB007839 exhibited a linear pharmacokinetic profile, with 
maximum concentrations and AUC increasing in a proportional manner. In addition, the 
simulation of repeated INCB007839 single-dose pharmacokinetic profile was accurately 
predicting the steady-state pharmacokinetic profile. The effect of food was tested using the SR 
formulation of INCB7983. Following administration of the SR INCB007839 after high-fat, high 
calorie meal, the drug exhibited a much slower absorption profile with a time to reach maximum 
concentration between 6 to 8 hours. Moreover, the INCB007839 maximum concentration and 
AUC were increased by approximately 100% and 80%, respectively, compared to the values 
obtained after fasted administration of SR INCB007839. The primary routes of elimination of 
INCB007839 are urinary excretion of unchanged INCB007839, glucuronidation, and hydrolysis 
to the carboxylic acid metabolite.  
 
2.2.3 Pediatric Clinical Trials 
No pediatric studies of INCB007839 have been conducted to date.  
 
2.3 
Rationale for proposed pediatric study 
Pediatric patients with recurrent/progressive high-grade gliomas have a very poor prognosis. 
Therapeutic agents to date have had limited success when targeting mechanisms intrinsic to the 
glioma cell. The use of an ADAM10 inhibitor like INCB007839 is a promising therapeutic strategy 
to target elements of the tumor microenvironment that promote glioma progression, and therefore 
represents a novel therapeutic strategy. 
 
Overall, INCB007839 is a safe and tolerable drug in adult patients with advanced cancer. In 
addition, the preclinical data described above suggests that INCB007839 inhibits growth in 
pediatric high-grade gliomas and DIPG. This study will allow a more detailed description of the 
safety and tolerability of INCB007839 in pediatric patients with recurrent/progressive high-grade 
gliomas and also obtain preliminary data regarding the efficacy of this treatment approach.  
 
Given that the adult recommended phase 2 (RP2D) dose of INCB007839 SR was 200 mg BID, we 
propose to test the safety and tolerability of pediatric equivalent dose based on a typical adult size 
of 1.67 m2: 120 mg/m2. Thus, this clinical trial will start at 120 mg/m2 and de-escalate to 80 mg/m2 
if the former is not tolerable. INCB007839 SR will be administered orally, twice a day each day 
for 28-day cycles. Treatment may continue up to 26 courses (2 years) in the absence of disease 
progression or unacceptable toxicity.  
 
Limited preclinical data suggest that ADAM10 deletion may be associated with abnormal bone 
growth; the potential effect of INCB007839 on bone development will therefore be monitored in 
this study by knee X-rays (that capture the tibial growth plate), and knee MRI if clinically 
indicated.

2.4 
Correlative Studies Background 
 
2.4.1 Rationale for Pharmacokinetic Studies 
 
2.4.1.1 Hypothesis 
The pharmacokinetics and tolerability of INCB007839 in pediatric patients with 
recurrent/progressive high-grade glioma will be similar as compared to prior studies of 
INCB007839 in the adult population.  
 
2.4.1.2 Preclinical and Clinical Data 
Pharmacokinetic studies will be essential for evaluating and interpreting toxicity and outcomes as 
there are no previous pediatric studies with INCB007839. Though it is hypothesized that the 
pharmacokinetics and tolerability will be similar between pediatrics and adults, there may be 
differences based on patients’ previous treatment, age, weight, body habitus, and other co-factors. 
Additionally, evaluating plasma Cmax and AUC and comparing to preclinical animal models will 
aid in understanding lack of efficacy, if present. Pharmacokinetic studies will be assessed pre-
treatment and post-treatment during Course 1. Based on the previously observed t1/2 life of this 
agent, samples will be collected after a single dose of INCB007839 for up to 48 hours post-
administration, on Days 1 and 2 of Course 1. Thus, the second dose of INCB007839 scheduled on 
Day 1 and the two doses scheduled on Day 2 will be held. Because the drug administration along 
with food will likely increase the inter-patient variability in the absorption process, the drug should 
be taken as much as possible without food (1 hour before or 2 hours after meals). Because it was 
shown in adults that the single-dose pharmacokinetic profile was able to accurately predict the 
steady-state pharmacokinetic profile, no other required pharmacokinetic samples will be collected 
in this study beyond 48 hours after the first dose. Cerebrospinal fluid collection is optional. 
 
2.4.2 Rationale for Other Correlative Studies 
 
2.4.2.1 Hypothesis 
Neuroligin-3 cleavage and secretion will be blocked with the use of INCB007839; we hypothesize 
that it is feasible to measure this in cerebrospinal fluid (CSF) samples from patients. HER2 and 
HER2 extracellular domain are also blocked; we hypothesize it is feasible to follow these in serum 
to monitor ADAM10 inhibitor pharmacodynamics. We will explore changes in these parameters 
with toxicity and outcome to determine if these may correlate with anti-tumor effects. 
 
2.4.2.2 Preclinical and Clinical Data 
Sources of NLGN3 include both normal brain and the glioma itself. NLGN3 expression in glioma 
cells is regulated by NLGN3 exposure and shedding is also mediated by ADAM10. ADAM10 
inhibition should block neuroligin-3 cleavage and secretion from both normal brain and from 
glioma cells based on preclinical data as stated above and as published.5 Changes in NLGN3 
secretion may be measurable in CSF samples. Optional CSF samples would allow researchers to 
monitor this exploratory measure as a potential pharmacodynamic biomarker.  
 
HER2 cleavage is mediated by ADAM10, and serum levels of the HER2 extracellular domain 
have been found to reflect ADAM10 inhibition. We will therefore test HER2 extracellular domain 
serum levels at Day 1 pre-dose and at Day 14 ± 2 days of Course 1.

2.4.3 Rationale for Amendment v3.0 (Protocol Version Date March 30, 2021), 
Anticoagulation 
Given the increased risk of thromboses in adult patients with cancer and the risk of bleeding in 
patients with CNS tumors, we initially opted not to include prophylactic anticoagulation and to 
reconsider as necessary if thrombosis was observed in this trial. One patient (16 years old) with 
multiply recurrent high-grade glioma and a history of multiple intratumoral hemorrhages suffered 
a Grade 5 venous sinus thrombosis 9 days after initiating study drug (and approximately 7 days 
after placement of a ventriculoperitoneal shunt for symptomatic hydrocephalus). Because the study 
drug carries a known risk of thrombosis, attribution was assessed as possibly related to study drug. 
Given the severity of this event, we are amending the protocol to revise the eligibility criteria and 
to institute thrombosis prophylaxis, as the risk:benefit in this population appears to favor this. 
 
2.4.4 Rationale for Amendment v4.0 (Protocol Version Date August 2, 2022), 
Response to report of PRES 
One patient enrolled on this study experienced posterior reversible encephalopathy syndrome 
(PRES) in the setting of hypertension, gliomatosis cerebri, seizure activity, and disease 
progression. The study was placed on temporary hold to accrual while further investigation took 
place including the study team, the PBTC Steering Committee, the PBTC Toxicity Monitoring 
Committee, and the PBTC DSMB. Per information provided by the drug supplier, Incyte 
Pharmaceuticals, in other trials using this investigational agent, no other reports of PRES have 
been reported as at least possibly attributed to INCB007839. There have been 4 reports of 
hypertension at least possibly related to INCB007839. As a result of the event that occurred on 
study and following discussions with the above groups, CIRB, and FDA, the risks of PRES and 
hypertension have been added as Rare/Serious potential adverse effects of INCB007839.

requires that women and members of minority groups and their subpopulations be included in all 
NIH-supported biomedical and behavioral research projects involving NIH-defined clinical 
research unless a clear and compelling rationale and justification establishes to the satisfaction of 
the funding Institute & Center (IC) Director that inclusion is inappropriate with respect to the 
health of the subjects or the purpose of the research. Exclusion under other circumstances must be 
designated by the Director, NIH, upon the recommendation of an IC Director based on a 
compelling rationale and justification. Cost is not an acceptable reason for exclusion except when 
the study would duplicate data from other sources. Women of childbearing potential should not be 
routinely 
excluded 
from 
participation 
in 
clinical 
research.

3.4 
Treatment at the Primary Institution 
All experimental protocol therapy should be dispensed and all on-treatment imaging studies should 
be obtained at a PBTC or study-participating institution. Laboratory studies, excluding 
pharmacokinetic and biologic assays, may be performed at a CLIA certified laboratory of the 
investigator’s choice with the exception of the dose finding period. Imaging utilized to determine 
eligibility may be performed at an outside institution if all required imaging sequences are included 
and the study is deemed of adequate quality by the treating team. All required physical 
examinations, laboratory parameters need to be performed at the primary PBTC or study-
participating institution during the dose finding period of the protocol. 
 
3.5 
Criteria to Start Treatment 
• Subjects must start therapy within 7 days of enrollment. 
• Laboratory values must be no older than 7 days prior to the start of therapy. If a test that is 
repeated post-enrollment and prior to the start of therapy is outside the limits for eligibility, 
it must be rechecked within 48 hours prior to the start of therapy. If rechecks are still outside 
the limits for eligibility, the patient may not receive protocol therapy and will be considered 
off study. 
• If, in the opinion of the treating physician, a patient’s neurologic condition significantly 
worsens within 72 hours prior to treatment, the patient should not start treatment and should 
be taken off study.

4.2 
CTSU Registration Procedures 
This study is supported by the NCI Cancer Trials Support Unit (CTSU). 
 
4.2.1 IRB Approval 
For CTEP and Division of Cancer Prevention (DCP) studies open to the National Clinical Trials 
Network (NCTN) and NCI Community Oncology Research Program (NCORP) Research Bases 
after March 1, 2019, all U.S.-based sites must be members of the NCI Central Institutional Review 
Board (NCI CIRB). In addition, U.S.-based sites must accept the NCI CIRB review to activate new 
studies at the site after March 1, 2019. Local IRB review will continue to be accepted for studies 
that are not reviewed by the CIRB, or if the study was previously open at the site under the local 
IRB prior to March 1, 2019. International sites should continue to submit Research Ethics Board 
(REB) approval to the CTSU Regulatory Office following country-specific regulations.  
 
Sites participating with the NCI Central Institutional Review Board (NCI CIRB) must submit the 
Study Specific Worksheet for Local Context (SSW) to the CIRB using IRBManager to indicate 
their intent to open the study locally. The NCI CIRB’s approval of the SSW is automatically 
communicated to the CTSU Regulatory Office, but sites are required to contact the CTSU 
Regulatory Office at 
 to establish site preferences for applying NCI 
CIRB approvals across their Signatory Network. Site preferences can be set at the network or 
protocol level. Questions about establishing site preferences can be addressed to the CTSU 
Regulatory Office by email or calling
. 
 
In addition, the Site-Protocol Principal Investigator (PI) (i.e., the investigator on the IRB/REB 
approval) must meet the following criteria to complete processing of the IRB/REB approval record: 
• Holds an Active CTEP status; 
• Rostered at the site on the IRB/REB approval (applies to US and Canadian sites only) and 
on at least one participating roster; 
• If using NCI CIRB, rostered on the NCI CIRB Signatory record; 
• Includes the IRB number of the IRB providing approval in the Form FDA 1572 in the 
RCR profile; and 
• Holds the appropriate CTEP registration type for the protocol.  
 
4.2.2 Additional Requirements 
Additional requirements to obtain an approved site registration status include: 
• An active Federal Wide Assurance (FWA) number; 
• An active roster affiliation with the Lead Protocol Organization (LPO) or a Participating 
Organization (PO); and 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
26 
• Compliance with all protocol-specific requirements (PSRs). 
 
4.2.3 Downloading Site Registration Documents  
Download the site registration forms from the protocol-specific page located on the CTSU 
members’ website. Permission to view and download this protocol and its supporting documents 
is restricted based on person and site roster assignment. To participate, the institution and its 
associated investigators and staff must be associated with the LPO or a Protocol Organization (PO) 
on the protocol. One way to search for a protocol is listed below. 
 
• Log in to the CTSU members’ website (https://www.ctsu.org) using your CTEP-IAM 
username and password; 
• Click on Protocols in the upper left of the screen 
o Enter the protocol number in the search field at the top of the protocol tree; or 
o Click on the By Lead Organization folder to expand, then select Pediatric Brain 
Tumor Consortium (PBTC) and protocol number PBTC-056. 
• Click on Documents, select Site Registration, and download and complete the forms 
provided. (Note: For sites under the CIRB, IRB data will load automatically to the CTSU.)  
 
4.2.4 Submitting Regulatory Documents 
Submit required forms and documents to the CTSU Regulatory Office via the Regulatory 
Submission Portal on the CTSU website.  
 
To access the Regulatory Submission Portal, log on to the CTSU members’ website, go to the 
Regulatory section, and select Regulatory Submission. 
 
Institutions with patients waiting that are unable to use the Regulatory Submission Portal should 
alert the CTSU Regulatory Office immediately at 
 in order to receive further 
instruction and support. 
 
4.2.5 Delegation of Task Log (DTL)  
Each site must complete a protocol-specific Delegation of Tasks Log (DTL) using the DTL 
application in the Delegation Log section on the CTSU members’ website. The Clinical 
Investigator (CI) is required to review and electronically sign the DTL prior to the site receiving 
an Approved site registration status and enrolling patients to the study. To maintain an approved 
site registration status the CI must re-sign the DTL at least annually and when a new version of 
the DTL is released; and activate new task assignments requiring CI sign-off. Any individual at 
the enrolling site on a participating roster may initiate the site DTL. Once the DTL is submitted 
for CI approval, only the designated DTL Administrators or the CI may update the DTL. 
Instructions on completing the DTL are available in the Help Topics button in the DTL application 
and include a Master Task List, which describes DTL task assignments, CI signature, and CTEP 
registration requirements.  
 
4.2.6 Checking Site Registration Status

4.3 
Patient Enrollment  
 
4.3.1 OPEN/IWRS 
The Oncology Patient Enrollment Network (OPEN) is a web-based registration system available 
on a 24/7 basis. OPEN is integrated with the CTSU regulatory and roster data and with the Lead 
Protocol Organization (LPOs) registration/randomization systems or the Theradex Interactive 
Web Response System (IWRS) for retrieval of patient registration/randomization assignment. 
OPEN will populate the patient enrollment data in NCI’s clinical data management system, 
Medidata Rave. 
 
Requirements for OPEN access: 
• A valid CTEP-IAM account; 
• To perform enrollments or request slot reservations: Must be on an LPO roster, ETCTN 
corresponding roster, or participating organization roster with the role of Registrar. 
Registrars must hold a minimum of an Associate Plus (AP) registration type;  
• If a Delegation of Tasks (DTL) is required for the study, the registrars must hold the 
OPEN Registrar task on the DTL for the site; and  
• Have an approved site registration for the protocol prior to patient enrollment. 
 
To assign an Investigator (IVR) or Non-Physician Investigator (NPIVR) as the treating, crediting, 
consenting, drug shipment (IVR only), or receiving investigator for a patient transfer in OPEN, 
the IVR or NPIVR must list the IRB number used on the site’s IRB approval on their Form FDA 
1572 in RCR. If a DTL is required for the study, the IVR or NPIVR must be assigned the 
appropriate OPEN-related tasks on the DTL. 
 
Prior to accessing OPEN, site staff should verify the following: 
• Patient has met all eligibility criteria within the protocol stated timeframes; and  
• All patients have signed an appropriate consent form and HIPAA authorization form (if 
applicable). 
 
Note: The OPEN system will provide the site with a printable confirmation of registration and 
treatment information. You may print this confirmation for your records.  
 
Access OPEN at https://open.ctsu.org or from the OPEN link on the CTSU members’ website.

Pharmacokinetic Studies 
 
5.2.1 Plasma Pharmacokinetic Studies 
Mandatory serial plasma pharmacokinetic (PK) studies will be conducted in all patients enrolled 
in this protocol during Course 1 on Days 1 and 2 of INCB007839 therapy.  
 
5.2.1.1 Serial Sampling Strategy 
Beginning on Day 1 of Course 1, serial whole blood samples for INCB007839 pharmacokinetic 
studies will be collected at the following timepoints (patients should take the first dose 1 hour 
before or at least 2 hours after eating): 
• Pre-dose 
• 1 hour (± 15 min) after first dose 
• 4 hours (± 15 min) after first dose 
• 8 hours (± 1 hour) after the dose 
• 24 hours (± 2 hours) after the dose 
• 48 hours (± 4 hours) after the dose 
 
Patients will be asked to hold the second INCB007839 dose on Day 1 and the two INCB007839 
doses on Day 2 of Course 1 so that pharmacokinetic studies can be performed to gain a baseline 
of INCB007839 disposition.  
 
After the first INCB007839 dose on Day 1, the next dose must be administered on Day 3 AFTER 
the collection of the 48-hour sample.

5.2.1.2 Collection and Handling of Specimens 
• Before the start of the pharmacokinetic studies: 
Sites should contact the Stewart Laboratory at St. Jude Children’s Research Hospital at 
 to request a Pharmacokinetic Kit for each patient enrolled on the 
study. The Pharmacokinetic Kit will provide the material to enable collection of samples. 
 
• During the pharmacokinetic studies: 
At each time point, 2 mL of blood will be collected into appropriate BD Vacutainer tubes with 
K2EDTA. When applicable, the sterile discard volume should be returned to the patient after the 
blood has been obtained. Samples should be centrifuged within 30 minutes of collection at room 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
31 
temperature for 2 minutes at 10,000 rpm. For facilities equipped with lower-speed centrifuges, 
samples may be centrifuged at 1,000 to 1300 x g for 10 minutes. Immediately after centrifugation, 
transfer the plasma supernatant to an individually labeled screw-top tube. Samples should be 
labeled with the PBTC study number, PBTC Accession Number, sample type, collection date, 
corresponding study timepoint (e.g., C1D1), and collection time on the corresponding sample label 
and affixed to the screw-top tube. Within 1 hour of sample collection, store plasma samples 
at -80°C until shipment.  
 
The Pharmacokinetic Data Collection Form (DCF) located on the PBTC-056 Protocol Webpage 
should be completed with the exact date and time that the sample was drawn and the exact date 
and time that the drug was administered. All the information on the DCF should be filled out, and 
the DCF must be included in the shipment with the pharmacokinetic specimens collected. 
 
Important remarks: 
- 
For children less than 13 kg or for children with subcutaneous ports, contact Dr. Clinton 
Stewart or his designee 
 for a reduced sampling 
strategy. 
- 
As much as possible, patients are asked to take INCB007839 without food (1 hour before or 2 
hours after meals). If the drug is taken along with food, this must be reported in the 
Pharmacokinetic DCF. 
- 
Further information regarding the sample collection, processing and shipping will be found in 
the Pharmacokinetic Collection, Processing & Shipment Manual available on the PBTC-056 
Protocol Webpage. 
 
5.2.1.3 Shipping of Specimens 
Samples should be shipped for delivery Monday through Thursday with a generous amount of dry 
ice enclosed to safeguard against shipping delays. Weekend and holiday deliveries should be 
avoided. Samples should be shipped within 30 days of the last sample being taken. The site should 
use the PBTC-056 PK FedEx account details, located on the PBTC-056 Protocol Webpage. Ship 
all pharmacokinetic samples along with the completed Pharmacokinetic DCF to:

In consenting patients for whom CSF is accessible, single or serial CSF pharmacokinetic studies 
will be conducted.  
 
5.2.2.1 Serial CSF Studies 
Ventricular CSF (0.5 mL) should be obtained at the following timepoints:  
• Pre-dose 
• 4 hours (± 30 min) after drug administration 
• 8 hours (± 30 min) after drug administration. 
 
Simultaneous plasma samples should be obtained at the time of all the CSF sample collections. 
 
5.2.2.2 Single CSF Studies 
CSF samples may be collected at any time after study enrollment where CSF is collected as part 
of the best clinical practice (e.g., those requiring CSF diversion or VP shunt revision during 
therapy, or research participants requiring shunt externalization for infection, or at the time of 
lumbar puncture or shunt tap as clinically indicated post-treatment).  
 
A simultaneous plasma sample should be obtained at the time of the CSF sample collection. 
 
5.2.2.3 Collection and Handling of Specimens 
• Before the start of the pharmacokinetic studies: 
Sites should contact the Stewart Laboratory at St. Jude Children’s Research Hospital at
 to request a Pharmacokinetic Kit for each patient enrolled on the 
study. The Pharmacokinetic Kit will provide the material to enable collection of samples. 
 
• During the pharmacokinetic studies: 
At each time-point, collect 0.5 mL of CSF in a screw-top tube along with concomitant plasma 
sample. Record the exact time that the CSF and plasma samples were obtained along with the exact 
time of drug administration on the CSF Pharmacokinetic DCF located on the PBTC-056 Protocol 
Webpage. Samples should be labeled with the PBTC study number, PBTC Accession Number, 
sample type, collection date, corresponding study timepoint (e.g., C1D1), and collection time. 
Samples should be stored at -80°C until shipped. All the information on the DCF should be filled

Exploratory Correlative Studies  
 
5.3.1 PBTC Central Review and Biorepository (PBTC CRB) Pathology and 
Exploratory Correlative Studies 
The Pathology Central Review and Biorepository (PBTC CRB)’s function is to collect, distribute, 
and store specimens for pathology review and planned correlative studies which support the 
laboratory objectives of this protocol. If the patient does not consent to participation in the 
repository, other correlative study samples should be submitted following the guidelines in 
the appropriate correlative study section. 
 
The CRB will also serve as a central repository for specimens collected for future research and 
leftover specimens (tumor tissue or blood) returned to the repository following the planned 
analysis from patients who consent to future research studies. These samples will be stored in the 
repository for undefined future studies which support the mission of the PBTC. If the patient does 
not consent to future research, remaining correlative study samples will be destroyed once 
the PBTC-056 analysis is complete. 
 
5.3.1.1 PBTC CRB Submission Guidelines  
If the patient consents to provide slides for submission to the repository at the time of participation 
in a PBTC trial the following should be submitted:  
 
• Tumor material 
Slides from the original and/or recurrent surgery should be prepared for storage. The site should 
provide up to twenty (20) unstained sections cut at 4 µm in thickness on (+) slides from the most 
representative section. Fewer unstained sections may be submitted based on size and availability 
of tissue. Preference is for tissue that has not previously been frozen. The corresponding pathology 
report(s) including immunohistochemical, special stains, and molecular/genetic results are to be 
uploaded to the PBTC using the secure File Upload system. These reports will be made available 
to the pathologist via a link in ProtoLab. 
 
Suitability of sections would be established by preparing one (1) H&E to ensure that the sections 
meet the following criteria:  
o histologically representative of the reported lesion 
o contain at least 60% viable tumor 
o no more than 40% necrosis 
 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022

• Peripheral Blood Mononuclear Cells (PBMCs) 
PBMCs may be collected by processing a 2–5mL whole blood specimen with Ficoll or collecting 
the specimen in a BD Vacutainer™ CPT™ Cell Preparation Tube with Sodium Citrate or similar 
tube which is available locally. Once separated, all pellets must be snap frozen and stored at least 
at -20oC prior to dry ice shipment 
 
5.3.1.2 Specimen Collection  
➢ Processing by Ficoll tube 
1. Collect 2–5mL of fresh blood into an EDTA tube. 
2. Transfer blood into a sterile 50 mL tube and add double the amount of PBS. MIX 
GENTLY. 
3. Set up another tube containing half of its total volume of Ficoll. For example, if 
there is 15 mL of blood + PBS, then use 7.5 mL of Ficoll (2:1 ratio). 
4. At very slow pace (approx. 2 mL/minute), layer the blood + PBS mixture onto 
the Ficoll so that the solutions DO NOT MIX. Spin the blood/Ficoll at 750 g in 
slow mode for 30 minutes @ 25°C. After spin you will see four distinct layers: 
plasma (top layer), white fluffy ring (2nd layer), Ficoll (3rd layer), and blood 
(bottom layer). 
5. Remove plasma layer down to about 1 mL above the white fluffy ring and discard.  
6. Collect the entire white fluffy ring. If ring is hard to see, also take extra liquid 
above. Then discard everything else. 
7. Place this fraction of white blood cells into a fresh 50 mL sterile tube with 20 mL 
of PBS. Spin down for 10 minutes @ 25°C, 750 x g in fast mode. Remove the 
supernatant. Add back to pellet 1 mL of PBS and spin for 5 min. at 4°C at 10,000 
rpm. Remove supernatant.  
8. Freeze the pellet of WBCs in a 2 mL cryovial and store at -80°C until shipment. 
Cryovials larger than 2 mL cannot be accepted by the PBTC CRB. 
9. Please ensure that the labeling system used is designed to withstand temperatures 
down to -80°C. Samples should be stored at -80°C until shipment. For short term 
storage (2–3 weeks) -20°C is acceptable. NOTE 4°C IS NOT ACCEPTABLE 
STORAGE.  
 
If it is not possible to collect the PBMC by Ficoll gradient then separation of PBMC can be 
conducted using CPT tube separation as an alternative. However, the PBMC pellet MUST BE 
frozen immediately and stored at -80oC. 
 
➢ Collection and Processing by CPT tube 
1. Peripheral blood should be collected in a BD Vacutainer CPT™ Cell Preparation 
Tube with Sodium Citrate or similar tube which is available locally. 8 mL and 4 
mL CPT tubes can be obtained from Fisher Scientific (Cat# 02-685-125, 02-688-
81) or Becton-Dickinson (BD No.362761, 362760). The 8 mL tubes have a 6 mL 
minimum draw and the 4 mL tubes have a 3 mL minimum draw.  
2. Centrifuge the CPT™ tube at 1500 x g for 30 minutes at room temperature (20oC 
to 25oC). DO NOT APPLY THE BREAK ON THE CENTRIFUGE. Use 
acceleration 5, brake 0 (“slow mode”).  
3. It may be necessary to spin the tube longer to ensure that all of the red blood cell 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
35 
components have been separated from the plasma layer through the polyester gel 
barrier. 
4. The tube should be removed immediately from the centrifuge. The mononuclear 
layer and plasma lie above the polyester gel plug. 
5. Using a sterile pipette, remove as much of the plasma component (upper half of 
the CPT tube) without disturbing the mononuclear layer if possible and discard. 
6. Transfer mononuclear cell layer (and some residual plasma layer) to a labeled 
15 mL conical centrifuge tube and add 5 mL sterile room temperature magnesium 
or calcium-free phosphate buffered saline (PBS) to fill the conical tube and recap. 
7. Centrifuge at 450 x g for 10 minutes at room temperature (20°C to 25°C). Use 
acceleration 9, brake (“fast mode”).  
8. Remove supernatant, being careful not to aspirate the cellular pellet at the bottom 
of the tube.  
9. Add 1 mL of sterile PBS to the pellet and gently re-suspend by pipetting up and 
down. Transfer the entire suspended pellet to the labeled 2 mL cryovial. Cryovials 
larger than 2 mL cannot be accepted by the PBTC CRB. 
10. Centrifuge the cryovial at 450 x g for 5 minutes (or spin down the microcentrifuge 
tube at 1300 x g for 5 minutes) at room temperature. Discard the supernatant. 
Store the cell pellet cryovial frozen at -80°C. For short term storage (2–3 weeks) 
-20°C is acceptable.

5.3.2 Pathology Central Review  
Retrospective central pathology review will be completed from the slides submitted to the PBTC 
CRB if the patient consents to the CRB. Pathologist review of slides submitted to the PBTC CRB 
will include the following elements:  
 
• Examination of H&E stained slides: For each subject, one (1) H&E stained slide per one 
representative block from the brain tumor, removed either at initial diagnosis or relapse, 
should be submitted for review. 
• Review of the corresponding pathology report(s) of the immunohistochemical, special 
stains, and molecular/genetic results from current and/or original primary tumor 
• If necessary, review of immunohistochemical or special stained slides. Slides submitted to 
the PBTC CRB will be digitized to 40X. H&E stained sections will be retained and filed 
at the CRB. Original immunohistochemical or special stain slides will be returned to the 
submitting institution.

Neuroimaging Studies 
Patients will have MRI brain (for primary brain HGG) or MRI spine (for primary spinal cord HGG) 
with and without contrast performed at the following timepoints: 
• Prior to therapy 
• After Courses 2, 4, and 6 
• After Courses 9, 12, 15, 18, 21, and 24 (approximately every 12 weeks) 
• Post-therapy (after Course 26) 
 
MRI spine should be performed prior to therapy and at the same time points as standard MRI brain, 
if clinically indicated. For primary spinal HGG, brain imaging should only be performed as 
clinically indicated. See Section 11 for details.  
 
Standard MR imaging will include Sagittal T1 MPRAGE, axial DWI, axial T2 FLAIR, axial T2, 
and post gadolinium sagittal T1 MPRAGE (with reconstructions) images. The standard MR 
parameters 
are 
listed 
on 
the 
PBTC 
NIC 
web 
page 
located 
at 
http://www.childrenshospital.org/research/centers-departmental-programs/pediatric-brain-tumor-
consortium-neuroimaging-center under Neuroimaging Studies/ Specific MR Imaging Sequences- 
Open PBTC Protocols. There is also a link to the same PBTC-NIC webpage from the PBTC-056 
Protocol Webpage.  
 
Volumetric analyses will be done at the Neuroimaging Center (NIC, Children’s Hospital Boston) 
via the Vitrea (Vitrea™) workstation, from the axial T2 FLAIR and T1-weighted post-contrast 
brain images. 
 
5.4.1 Neuroimaging Review 
Local review of MR imaging studies will be performed at each site and central review of the MR 
imaging studies will be conducted through the PBTC Neuroimaging Center (NIC). NIC review 
will include assessment of response to therapy (as feasible). The director and one neuroradiologist 
of NIC will review the imaging studies at study completion. If the local and central review are not 
in agreement, the NIC neuroradiologist will confer with the participating site to determine why 
there is a discrepancy via conference call. 
 
For patients whose MRI scans suggest a response, a confirmation scan should be obtained 
approximately 8 weeks later. This scan, as well as the baseline and best response scans, will be 
electronically transferred to the PBTC Neuroimaging Center (NIC) for central review at the 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
39 
completion of the study. All patient specific data are stripped from the images and replaced with 
PBTC Accession numbers prior to transmitting the images to the NIC. All image data transfer is 
accomplished using PGP (pretty-good-privacy) 128-bit encryption which meets industry standard 
for secure communication. 
 
 
6.0 
TREATMENT PLAN 
Treatment can be administered on an outpatient basis. Reported adverse events and potential risks 
are described in Section 10. Appropriate dose modifications are described in Section 7. No 
investigational or commercial agents or therapies other than those described below may be 
administered with the intent to treat the patient's malignancy. Alternative therapies such as 
cannabinoids (cannabis oil, THC, etc.) will not be allowed. 
 
Timing of protocol therapy administration and response assessment studies are based on schedules 
derived from the experimental design or on established standards of care. Minor unavoidable 
departures from protocol directed therapy and/or disease evaluations for valid clinical, patient and 
family logistical, or facility, procedure and/or anesthesia scheduling issues are acceptable and 
should be documented. Contact a Study PI and the responsible Protocol Coordinator if there are 
any questions. 
 
6.1 
Agent Administration 
This is a phase 1 dose finding trial in pediatric patients with recurrent/progressive high-grade 
glioma, including DIPG and other diffuse high-grade gliomas. 
 
Given that the adult RP2D was 200 mg PO BID, we plan to evaluate the safety and tolerability of 
approximate pediatric equivalent dose based on a typical adult size of 1.67 m2. Thus, we propose 
to start at 120 mg/m2 and de-escalate to 80 mg/m2 if this dose is not tolerable.  
 
INCB007839 is administered orally (PO), twice a day each day for 28-day cycles. A medication 
diary will be required to ensure appropriate drug administration (Appendix C). The patient will be 
requested to maintain the medication diary documenting each dose of medication. The medication 
diary will be returned to clinic staff at the end of each course.  
 
Given the known risk of thrombosis associated with INCB007839, DVT prophylaxis is required 
with low molecular weight heparin (LMWH, e.g., enoxaparin at 1 mg/kg/day [can be divided BID] 
with a maximum dose of 40 mg/day), with a goal of anti Xa level of 0.3–0.5 units/mL. DVT 
prophylaxis should continue throughout the duration of treatment and for 2 weeks after cessation 
of study drug, except as noted below.  
 
• If a contraindication to DVT prophylaxis occurs (e.g., a new injury at risk of bleeding, 
planned invasive procedures, allergy to pork products, etc.), the study drug should be held 
at the time of LMWH cessation. LMWH should be held in these instances per institutional 
standards or the treating physician’s discretion if no guidelines exist. If the temporary risk 
of anti-coagulation resolves, patients may restart INCB007839 with concurrent LMWH at 
the discretion of the treating physician.

6.1.1 INCB007839 
INCB007839 is supplied as 100 mg sustained release tablets. Patients will receive INCB007839 
orally twice a day each day for 28-day cycles. Patients may continue to receive INCB007839 on 
study for up to 26 courses (approximately 2 years) in the absence of disease progression or 
unacceptable toxicity. Enrolled patients will be followed after completion of study therapy for 2 
years or death, whichever occurs first. Delays between courses for reasons other than toxicity may 
occasionally occur, however, dosing should follow the treatment plan as closely as possible. 
Discuss and document any protocol deviations with the Study Chair. Duration of therapy is defined 
in Section 6.4.  
 
Dosing should be adjusted based on body surface area (BSA) calculated at the beginning of each 
course of therapy. The dose prescribed should be rounded to the nearest deliverable dose based on 
the BSA adjustment and the available pill size. Dosing tables which reflect this approach are 
available in Appendix B. Patients will be provided with a medication diary for INCB007839, 
instructed in its use, and must bring the diary as well as the remaining pill bottles with them to 
each appointment. The medication diary is in Appendix C. 
 
As much as possible, INCB007839 should be taken without food (1 hour before meals or 2 hours 
after), with water rather than other fluids. Dosing is every 12 hours (± 2 hours), but if a dose is not 
given within 4 hours, consider it missed. If a dose is missed, it should be documented in the diary 
and the next scheduled dose should be taken as scheduled. Patients who vomit a dose of 
INCB007839 should NOT be re-dosed, and appropriate anti-emetic therapy should be 
implemented prior to the next scheduled dose.  
 
6.1.2 Criteria to start subsequent courses 
A course may be repeated every 28 days if the patient has at least stable disease and has again met 
laboratory parameters as defined in Section 3.1.9, and 3.1.14 if applicable.  
• If a patient does not meet these parameters at the end of the dose-finding period, then 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
41 
INCB007839 should be held until parameters meet the criteria. If parameters are not met 
within 7 days of the scheduled course to begin, this is a dose-limiting toxicity (see Section 
6.2) and dose reduction is indicated.  
• If a patient does not meet these parameters at the end of subsequent courses (i.e., Course 2 
and onward), then INCB007839 should be held until parameters meet the criteria. If 
parameters are not met within 7 days of the scheduled course to begin, this will require a 
dose modification (see Section 7.0). 
• If INCB007839 is held for any reason other than toxicity (e.g., planned procedure), it can 
be restarted (with concurrent anti-coagulation) at the same dose and with counting of 
course days continuing (e.g., if INCB007839 is held on Days 13–16 of a course due to a 
shunt revision, restart INCB007839 and LMWH on Day 17 and continue counting course 
days for a 28-day course). 
 
6.2 
Definition of Dose-Limiting Toxicity (DLT)  
DLT will be defined as any of the events listed in this section that are at least possibly related to 
the investigational agent and that occur during the dose-finding period regardless of expectedness.  
• Any INCB007839-related adverse event during the first course of therapy that leads to a 
dose reduction or results in the permanent cessation of therapy will be considered dose 
limiting. All dose modifications in all courses are to follow the guidelines provided. 
• Any INCB007839-related adverse event during the first course of therapy that results in a 
delay of treatment > 7 days. 
 
6.2.1 Non-hematologic dose limiting toxicity is defined as: 
• Any Grade 4 non-hematologic toxicity 
• Any Grade 3 non-hematologic toxicity with the exception of: 
o 
Grade 3 nausea and vomiting of < 5 days and responsive to anti-emetic treatment 
o 
Grade 3 elevation of transaminases that returns to levels meeting eligibility 
criteria within 7 days of study drug interruption and does not recur upon restarting 
drug.  
o 
Grade 3 fever or infection of fewer than 5 days in duration 
o 
Grade 3 hypophosphatemia, hypokalemia, hypocalcemia, or hypomagnesemia 
responsive to oral supplementation 
• Any Grade 2 non-hematologic toxicity that persists for > 7 days and is considered 
medically significant or sufficiently intolerable by the patient that the toxicity requires 
treatment interruption 
• Any deep venous thrombotic event (superficial phlebitis is excluded unless Grade 3 or 4 
as above) 
o If a patient on this study has a thrombotic/thromboembolic event that is not related 
to the central line, treatment with INCB007839 will be discontinued and not 
restarted. Determination of attribution will be reviewed by the study team and 
discussed with PBTC Toxicity Committee and CTEP; and such events will be 
reported to the CTEP-AERS, PBTC DSMB, and the FDA as events of special 
interest in an expedited fashion. See special reporting requirements in Section 10.3. 
In this event, enrollment will be halted until fully reviewed. In addition, any patient 
experiencing a non-central line-related thromboembolic event should have the 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
42 
studies listed below performed as soon as possible after the event.  
 
o Patients with a venous thrombosis should have the following assessed as soon as 
possible after thrombosis is suspected/confirmed: 
- 
CBC 
- 
Antithrombin 
- 
Protein C  
- 
Protein S  
- 
Factor V Leiden 
- 
Prothrombin G20210A gene analysis 
- 
Fasting serum homocysteine 
- 
Lupus anticoagulant assays 
- 
Anticardiolipin level 
 
o Patients with an arterial thrombosis should have: 
- 
CBC  
- 
Fasting serum homocysteine 
- 
Lupus anticoagulant 
- 
Anticardiolipin level 
- 
LDL, HDL, triglycerides 
 
6.2.2 Hematologic dose limiting toxicity is defined as: 
• Any Grade 4 hematologic toxicity with the exception of lymphopenia 
• Grade 3 neutropenia with fever 
• Requiring a platelet transfusion (threshold for transfusion is a platelet count of 
< 50,000/µL) on 2 separate days (following adequate initial platelet transfusion to 
> 100,000/µL) during a single course.  
 
Management and dose modifications associated with the above adverse events are outlined in 
Section 7. 
 
6.2.3 Dose-finding period 
The dose-finding period begins with the initial dose of INCB007839 and ends on the last day of 
Course 1. Should there be a delay starting the subsequent course, dose-finding will complete on 
the start date of Course 2.  
 
Management and dose modifications for toxicities which occur outside of the dose-finding period 
should also follow guidelines in Section 7, however, these will not be considered dose limiting for 
the purpose of dose finding. 
 
6.2.4 Dose De-escalation 
Dose de-escalation will proceed as follows: 
 
• Course 1 will be started with an initial cohort of six (6) patients at 120 mg/m2/dose BID 
(the dose levels to be tested are listed in Table 3). If more than 1 DLT is observed in 6 
patients treated at Dose Level 1, de-escalation to Dose Level 0 will occur as outlined in 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
43 
Section 9.1. Only DLTs observed during the dose finding period of therapy will be used to 
guide dose de-escalation. Patients treated at Dose Level 0 who have a DLT will discontinue 
study therapy. 
 
• If thrombosis occurs outside of the DLT period, this will be discussed with study team to 
determine attribution to study drug, potential dose-association, as well as consideration of 
the risk/benefit ratio of prophylaxis in subsequent patients. 
 
• Patients enrolled on Dose Level 1 who have a dose-modifying toxicity outside of the dose-
finding period (e.g., in Courses 2 and onward) should have the dose of INCB007839 
reduced on subsequent courses to Dose Level 0. Patients can begin the subsequent course 
at the lower dose when the toxicity has resolved to Grade 1 or baseline and laboratory 
parameters are met as defined in Section 3.1.9 and 3.1.14. Patients enrolled on Dose 
Level 0 who require a dose reduction will not receive further treatment on study and will 
be considered off treatment (see Section 6.4.2). 
 
6.3 
General Concomitant Medication and Supportive Care Guidelines 
 
6.3.1 Steroids 
Corticosteroids should be used at the lowest dose to control symptoms of edema and mass effect, 
and discontinued, if possible. Use of corticosteroids should be recorded in the RAVE database. 
Steroids should not be used to control other symptoms, e.g., nausea. 
 
6.3.2 Anticonvulsants  
Anticonvulsants should be used, if indicated. Use of anticonvulsants should be recorded in the 
RAVE database.  
 
6.3.3 Growth Factors 
Routine use of growth factors (e.g., G-CSF, GM-CSF, and erythropoietin) is not permitted. 
However, therapeutic use of G-CSF or GM-CSF in patients with serious neutropenic conditions, 
such as sepsis, may be considered at the investigator’s discretion. Use of growth factors should be 
recorded in the RAVE database. 
 
6.3.4 Anti-emetics 
The use of anti-emetics will be at the investigator’s discretion. Use of anti-emetics should be 
recorded in the RAVE database. 
 
6.3.5 Febrile neutropenia 
Febrile neutropenia should be managed according to the local institutional guidelines. Measures 
include laboratory testing, blood and urine cultures, and institution of broad-spectrum antibiotics. 
 
6.3.6 Antihypertensive Medications 
Hypertension should be managed, if indicated. Antihypertensives to maintain blood pressure 
below the 95th percentile for age, height, and gender (based on the normal blood pressure chart 
available in the Generic Forms section of the PBTC member’s website) are allowed per the 
discretion of the treating physician according to institutional guidelines. Use of antihypertensive 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
44 
medications should be recorded in the RAVE database. 
 
6.3.7 Pneumocystis jiroveci pneumonia (PJP) prophylaxis 
The use of medication (i.e., Bactrim) for PJP prophylaxis in patients on chronic steroids is 
recommended, but it is at the investigator’s discretion. 
 
6.3.8 Neurosurgical or other surgical procedures 
If a neurosurgical procedure or other surgical procedure is required for a reason other than tumor 
progression (e.g., the onset of hydrocephalus), these procedures should be documented but will 
not constitute criteria for declaring the patient “off therapy”. INCB007839 should be held after 
any surgical intervention (with the exception of minor dental or dermatological procedures) for at 
least 28 days after surgery. LMWH should be held as indicated for the surgical procedure but 
restarted as soon as deemed safe by the treating surgeon. 
 
6.4 
Duration of Therapy 
In the absence of treatment delays due to adverse event(s), treatment on study may continue up to 
26 courses (approximately 2 years) or until further disease progression, unacceptable toxicity, 
withdrawal of consent, or until one of the following Off Treatment criteria in Section 6.4.2 applies.  
 
6.4.1 On Study Data Submission Schedule 
Pre-treatment, on-study, and off-treatment data, as well as patient response data are to be recorded 
in the electronic data collection screens using the RAVE database. See the Required Data and 
Timetable for Submission form located on the PBTC-056 Protocol Webpage for the schedule. For 
assistance, contact the PBTC Protocol Coordinator listed on the cover page.  
 
6.4.2 Off Treatment Criteria 
At the discontinuation of treatment, the “Off Treatment Date” is to be recorded in the eCRF and 
is to be consistent with the reason given for going off treatment. The “Last Treatment Date” is 
defined as the last date that the patient received protocol based therapy. The reason for 
discontinuation of treatment must be documented by the attending investigator in the medical 
record and recorded in the eCRF.  
 
Patients will be considered Off Treatment for the following reasons: 
• Development of unacceptable toxicity as outlined in Section 6.2. See Section 10.3 and 10.4 
for specific reporting requirements. 
• Progressive disease (PD) as described in Section 12.2.  
• Development of a medical or psychiatric illness that in the investigator's judgment renders 
the patient incapable of further therapy on this protocol or the treating physician determines 
continuation on this study is not in the patient’s best interest.  
• The patient, parent, or legal guardian refuses further treatment on this protocol. In this case 
the investigator should clarify if the family also wishes to withdraw consent for continued 
participation for data collection purposes.  
• Completion of all protocol defined treatment 
• Pregnancy 
• Non-Compliance that in the opinion of the investigator does not allow for ongoing 
participation. 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
45 
• Termination of the study by the sponsor 
• Investigational agent manufacturer can no longer provide the study agent. 
• Development of a non-central line related thrombosis 
 
Patients who are off protocol therapy must be followed until an “Off Study Criterion” is met. 
 
6.4.2.1 Data Submission Schedule for Patients Off Treatment 
All patients must be followed for a minimum of 30 days from the last treatment date. Toxicities 
that are considered at least possibly related to study treatment and are ongoing at the end of day 30 
of last treatment date will be followed until resolution or return to baseline, unless consent is 
withdrawn for further data submission or follow-up.  
 
Patients who do not meet an off-study criterion will continue to be followed for 2 years from the 
last dose of protocol treatment for the monitoring of unexpected later developing toxicities or other 
morbidity and to document disease progression and survival. Data should be updated quarterly in 
the RAVE database. The requested follow-up data, including imaging uploads requested in Section 
5.4, are to be submitted quarterly in the RAVE database from the date the patient went off 
treatment. Data to be recorded during this interval are the following:  
 
• Any adverse events that are possibly, probably, or definitely related to the study drug (see 
Section 10 for specific reporting timelines)  
• Dates of disease assessment and results of the associated disease assessments. 
• Date of disease progression 
• Date of commencement of new anticancer therapy  
• Date of most recent contact  
• Date of death 
 
6.4.3 Criteria for Removal from Study 
Patients who are off protocol therapy will be followed until they meet criteria for removal from 
study. The date and reason for the patient coming off study must be documented in the eCRF and 
the Operations, Biostatistics and Data Management Core (OBDMC) must be notified according to 
standard reporting guidelines (see Sections 10.3, 10.4, and 13.2, Data submission for Off Study, 
and the Required Data and Timetable Submission from located on the PBTC-056 Protocol 
Webpage).  
 
Ongoing AEs, or AEs that emerge after the patient is removed from protocol therapy but within 
30 days of the last dose of study treatment, must be followed and reported via Rave and CTEP-
AERS (if applicable). Toxicities that are at least possibly related to the study treatment and are 
ongoing at the end of day 30 of last treatment date will be followed until resolution or return to 
baseline, whichever is longer.

• Patient determined to be ineligible. 
o 
If the patient was found to be ineligible after starting treatment, follow-up should 
continue for 30 days from the last administration of study drug or until any drug-
related toxicity resolves or returns to baseline, whichever is longer.  
• Patient did not initiate treatment on study. 
• Parent, patient, or guardian withdraws consent for further required observations of data 
submission. 
• Patient death while on study. The IRB, Study Chair, and OBDMC must be notified as per 
Section 10.3. 
• Patient has started another anti-cancer therapy. Follow-up must still be completed for 30 
days following the last treatment date. 
• Patient has completed study follow-up which is defined as 2 years following last dose of 
INCB007839.  
• Progressive disease  
o 
If PD occurs within less than 30 days of off-treatment date, then follow-up should 
continue until 30 days from off-treatment date.  
o 
If the off-treatment reason is toxicity and the patient is subsequently found to 
have PD, then follow-up should continue for 30 days from the off-treatment date 
or until the toxicity resolves or returns to baseline, whichever is longer.  
 
6.4.3.1 Data Submission for Patients Off study 
No data will be collected documenting treatment or reporting events or disease status that occur 
subsequent to the official “off study” date with the exception of adverse events with an attribution 
of possible, probable, or definite that occur after the “off study” date.  
 
 
7.0 DOSING DELAYS/DOSE MODIFICATIONS 
The Study Chair or Co-Chair must be notified of any dosage modifications, prior to the 
implementation of the dose modification. There is only one dose reduction planned for this study. 
Patients receiving INCB007839 80 mg/m2 BID daily and who meet criteria for a dose reduction 
must be removed from protocol therapy.

agent strength, formulation and ordering investigator on this protocol.  
 
 
9.0 
STATISTICAL CONSIDERATIONS 
 
9.1 
Study Design/Endpoints 
The primary aims of this study are to evaluate the safety and tolerability of INCB007839 and 
identify the maximum tolerated dose or the recommended phase 2 dose in children and young 
adults with recurrent/progressive CNS tumors. Based on this approach we propose to enroll 6 
patients at Dose Level 1. If we observe no more than 1 DLT, enrollment on this dose level will be 
expanded to at least 12 subjects in order to obtain additional PK and safety information. If Dose 
Level 1 is not tolerable then we will de-escalate to Dose Level 0 and repeat the same process. If 
more than 3 DLTs are observed in 12 subjects at Dose Level 1, then the initially identified MTD 
based on 6 subjects will be considered unsafe and a dose de-escalation to Dose Level 0 will be 
considered.  
 
We will use a design similar to the Rolling-6 design and open 6 slots initially on Dose Level 1. If 
we observe no-more than 1 DLT in these 6 subjects then we would expand this cohort to at least 
12 patients for PK and additional safety information. If more than 1 DLT is observed on Dose 
Level 1 in 2–6 subjects, then further enrollment to Dose Level 1 will stop, the dose will be de-
escalated to Dose Level 0 and the same approach will be repeated.  
 
Based on the above-outlined de-escalation rules, if Dose Level 0 is found to be too toxic, then the 
trial will be closed to accrual and the merits of amending or closing the trial permanently will be 
reconsidered.  
 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
49 
Accrual will be suspended for any Grade 5 AE which is at least possibly attributable to the study 
agent until a full assessment can be made. At that time, the toxicity data and all associated 
information will be reviewed by the study committee, the PBTC toxicity monitoring committee 
and DSMB, CTEP, and by the FDA prior to a deliberate decision to resume accrual.  
 
Similarly, if a patient on this study has a thrombotic/thromboembolic event that is not related to 
the central line (except superficial phlebitis), treatment with INCB007839 will be discontinued 
and not restarted for that subject. Determination of attribution will be reviewed by the study team 
and discussed with PBTC Toxicity Committee and CTEP. A list of such events that will be 
reported to the CTEP-AERS, PBTC DSMB, and the FDA as events of special interest in an 
expedited fashion are in Section 10.3.  
 
9.2 
Sample Size/Accrual Rate 
 
9.2.1 Projected Accrual Rages and Study Duration 
If Dose Level 1 is determined to be safe then the study could be completed for the 
safety/tolerability assessment with 15 patients (including a few who may be inevaluable). The 
maximum sample size is ~28, in the event that we de-escalate to Dose Level 0 after 12 patients are 
treated at Dose Level 1.  
 
The projected accrual rate is 1–2 patients per month, based on knowledge of the member 
institutions and their commitment to the Consortium. With 2 possible dose levels, the study 
duration is estimated to be 1.5–2 years from study activation, if both dose levels are investigated.

9.2.2 Statistical Analysis of Pharmacokinetics/Pharmacogenetics 
The plasma INCB007839 concentration-time data will be analyzed using non-compartmental 
and/or population-based compartmental methods. Individual pharmacokinetic parameters of 
interest such as the area under the curve after single dose from 0 to ∞ [AUC0-∞], maximum 
concentration [CMAX], time to reach CMAX [TMAX], and apparent oral clearance [CL/F] will be 
calculated based on the Course 1 Days 1 and 2 pharmacokinetic samples. 
 
9.3 
Data Analysis 
As part of routine analyses, toxicities will be summarized by dose level, by grade, and by 
attribution. These analyses will also take into account the actual dosage received by subjects to 
ensure that large deviations in dosage that will likely occur due to limitations in the formulation 
of the agent do not lead to safety concerns. Furthermore, at the end of the study, we will explore 
associations between PK parameters (such as Cmax and AUC) and higher grade toxicities that 
may help identify safety trends.  
 
Because this is a phase 1 study, observations of objective responses are expected to be rare. Thus, 
these will be reported in a descriptive fashion. Similarly, the exploratory marker studies for HER-
2 and neuroligin-3 will be summarized based on descriptive statistics and plots without formal 
inference. 
  
 
10.0 
ADVERSE EVENTS: LIST AND REPORTING REQUIREMENTS  
Adverse event (AE) monitoring and reporting is a routine part of every clinical trial. The following 
list of AEs (Section 10.1) and the characteristics of an observed AE (Sections 10.2 and 10.3) will 
determine whether the event requires expedited reporting via the CTEP Adverse Event Reporting 
System (CTEP-AERS) in addition to routine reporting. 
 
• Baseline Abnormalities 
Any baseline (pre-treatment) abnormalities observed during the initial physical examination 
should be recorded in the RAVE database. 
 
• Treatment or within 30 days of treatment 
Only record adverse events Grades 1 and 2 in the electronic case report forms (CRFs) if the 
attribution is at least possibly related to INCB007839. Record all adverse events Grades 3 through 
4 and deaths), regardless of attribution on the electronic case report forms.

10.3 
Expedited Adverse Event Reporting 
 
10.3.1 CTEP-AERS 
Expedited AE reporting for this study must use CTEP-AERS (CTEP Adverse Event Reporting 
System), accessed via the CTEP website (https://eapps-ctep.nci.nih.gov/ctepaers). The reporting 
procedures to be followed are presented in the “NCI Guidelines for Investigators: Adverse Event 
Reporting Requirements for DCTD (CTEP and CIP) and DCP INDs and IDEs” which can be 
downloaded from the CTEP website  
(http://ctep.cancer.gov/protocolDevelopment/electronic_applications/adverse_events.htm). These 
requirements are briefly outlined in the tables below (Section 10.3.4). 
 
In the rare occurrence when Internet connectivity is lost, a 24-hour notification is to be made to 
CTEP by telephone at 
. Once internet connectivity is restored, the 24-hour 
notification phoned in must be entered electronically into CTEP-AERS by the original submitter 
at the site. 
 
10.3.2 Distribution of Adverse Event Reports 
CTEP-AERS is programmed for automatic electronic distribution of reports to the following 
individuals: Principal Investigator and Adverse Event Coordinator(s) (if applicable) of the 
Corresponding Organization or Lead Organization, the local treating physician, and the Reporter 
and Submitter. CTEP-AERS provides a copy feature for other e-mail recipients.  
 
The following must be copied on expedited reports (24-hour notification and the complete report) 
submitted via CTEP-AERS:

The OBDMC will email and/or fax the SAE/CTEP-AERS report within 24 hours of their 
awareness of the event to Incyte Corporation via email to 
 or fax 
.  
 
The IND holder, St. Jude Children’s Research Hospital, shall notify the FDA of any event that is 
both a suspected unexpected serious adverse reaction (SUSAR) in accordance with FDA rules and 
regulations (21 CFR 312.32). Follow-up information to a safety report will be submitted, as 
requested. 
 
The IND Sponsor or designee will submit a report of the suspected unexpected serious adverse 
event to the FDA. The FDA prefers these reports to be made on a MedWatch 3500A form, but 
alternative formats are acceptable (e.g., a summary letter). The report should describe the event as 
fully as possible. Supporting documentation (lab reports, summary notes, and autopsy report) 
should accompany the report. A fatal or immediately life-threatening suspected adverse event will 
be reported to the FDA within 7 calendar days of the receipt of the initial report by the IND 
sponsor. A non-fatal, non-life threatening unexpected, suspected, serious adverse event will be 
reported to the FDA within 15 calendar days of receipt of the initial report by the IND Sponsor.  
 
The PBTC OBDMC will post all IND Safety Letters on the PBTC-056 webpage. Sites will be 
notified via email of the receipt of the IND Safety Letter(s) and instructed to submit these to their 
local IRB in accordance with the institution’s requirements.  
 
The IND Annual Report will be submitted by the IND holder as required by the FDA. This 
submission will be cross referenced according to local regulations to the Incyte/ INCB007839 at 
the time of submission.  
 
10.3.3 Expedited Reporting Guidelines 
Use the NCI protocol number and the protocol-specific patient ID assigned during trial registration 
on all reports. 
 
Note: A death on study requires both routine and expedited reporting, regardless of causality 
as long as the death occurred within 30 days after the last administration of the 
investigational agent. Attribution to treatment or other cause must be provided. 
 
Death due to progressive disease should be reported as Grade 5 “Disease progression” in the 
system organ class (SOC) “General disorders and administration site conditions.” Evidence that 
the death was a manifestation of underlying disease (e.g., radiological changes suggesting tumor 
growth or progression: clinical deterioration associated with a disease process) should be 
submitted.

Investigational Agent/Intervention 1, 2 
FDA REPORTING REQUIREMENTS FOR SERIOUS ADVERSE EVENTS (21 CFR Part 312) 
NOTE:  Investigators MUST immediately report to the sponsor (NCI) ANY Serious Adverse Events, whether or not 
they are considered related to the investigational agent(s)/intervention (21 CFR 312.64) 
An adverse event is considered serious if it results in ANY of the following outcomes:   
1) 
Death 
2) 
A life-threatening adverse event  
3) 
An adverse event that results in inpatient hospitalization or prolongation of existing hospitalization for ≥ 24 
hours  
4) 
A persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions  
5) 
A congenital anomaly/birth defect.  
6) 
Important Medical Events (IME) that may not result in death, be life threatening, or require hospitalization 
may be considered serious when, based upon medical judgment, they may jeopardize the patient or 
subject and may require medical or surgical intervention to prevent one of the outcomes listed in this 
definition. (FDA, 21 CFR 312.32; ICH E2A and ICH E6). 
 
ALL SERIOUS adverse events that meet the above criteria MUST be immediately reported to the NCI via electronic 
submission within the timeframes detailed in the table below.

10.3.4 Special Expedited Reporting Requirements for the Study 
The following thromboembolic events (Grades 1–5) should be reported expeditiously through 
CTEP-AERS regardless of attribution of study drug:  
• Arterial thromboembolism 
• Superior vena cava syndrome 
• Thromboembolic event 
• Vascular disorder (other) 
• Thrombotic thrombocytopenic purpura 
• Myocardial infarction 
• Visceral arterial ischemia 
• Budd-Chiari syndrome 
• Portal vein thrombosis 
• Sinusoidal obstruction syndrome 
• Ischemia cerebrovascular 
• Stroke 
• Transient ischemic attacks 
 
The following events should follow the serious adverse events reporting requirements described 
in the table above:  
• Superficial thrombophlebitis 
• Phlebitis 
• Vasculitis 
• Hemorrhoids 
• Phlebitis infective 
• Intraoperative venous injury 
• Vascular access complication 
• Avascular necrosis 
 
10.4 
Routine Adverse Event Reporting 
All Adverse Events must be reported in routine study data submissions. AEs reported 
expeditiously through CTEP-AERS must also be reported in routine study data submissions. 
 
Adverse event data collection and reporting, which are required as part of every clinical trial, are 
done to ensure the safety of patients enrolled in the studies as well as those who will enroll in 
future studies using similar agents. AEs are reported in a routine manner at scheduled times during 
the trial using Medidata Rave. For this trial the Adverse Event CRF is used for routine AE reporting 
in Rave. 
 
10.5 
Pregnancy 
Although not an adverse event in and of itself, pregnancy as well as its outcome must be 
documented via CTEP-AERS. In addition, the Pregnancy Information Form included within the 
NCI Guidelines for Adverse Event Reporting Requirements must be completed and submitted to 
CTEP. Any pregnancy occurring in a patient or patient’s partner from the time of consent to 90 
days after the last dose of study drug must be reported and then followed for outcome. Newborn 
infants should be followed until 30 days old. Please see the “NCI Guidelines for Investigators: 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
56 
Adverse Event Reporting Requirements for DCTD (CTEP and CIP) and DCP INDs and IDEs” (at 
http://ctep.cancer.gov/protocolDevelopment/adverse_effects.htm) for more details on how to 
report pregnancy and its outcome to CTEP.  
 
10.6 
Secondary Malignancy 
A secondary malignancy is a cancer caused by treatment for a previous malignancy (e.g., treatment 
with investigational agent/intervention, radiation or chemotherapy). A secondary malignancy is 
not considered a metastasis of the initial neoplasm. 
 
CTEP requires all secondary malignancies that occur following treatment with an agent under an 
NCI IND/IDE be reported expeditiously via CTEP-AERS. Three options are available to describe 
the event:  
• Leukemia secondary to oncology chemotherapy (e.g., acute myelocytic leukemia)  
• Myelodysplastic syndrome (MDS)  
• Treatment-related secondary malignancy  
 
Any malignancy possibly related to cancer treatment (including AML/MDS) should also be 
reported via the routine reporting mechanisms outlined in each protocol. The Adverse Event eCRF 
should be updated with the appropriate description within 1 week of learning of the secondary 
malignancy. 
 
10.7 
Second Malignancy 
A second malignancy is one unrelated to the treatment of a prior malignancy (and is NOT a 
metastasis from the initial malignancy). Second malignancies require ONLY routine AE reporting 
unless otherwise specified.

MEASUREMENT OF EFFECT 
Although the clinical benefit of INCB007839 has not yet been established, the intent of offering 
this treatment is to provide a possible therapeutic benefit, and thus the patient will be monitored 
for tumor response and symptom relief in addition to safety and tolerability. In addition to a 
baseline scan, confirmatory scans will also be obtained approximately 8 weeks following initial 
observation of an objective response. 
 
12.1 
Antitumor Effect Definitions 
• Evaluable for Toxicity 
Patients who receive at least 1 dose of INCB007839 and experience a DLT or are removed from 
treatment for study agent-related toxicity during the dose finding period (first 28 days of treatment) 
are evaluable for estimating the MTD. 
 
Patients who receive approximately 85% (at least 45/53 of required doses; at least 23/27 required 
doses for patients enrolled on Dose Level 0 who have BSA 0.55–1.0 m2) of prescribed therapy 
during the dose finding period will be considered evaluable for estimating the MTD, as long as no 
additional anti-cancer therapy or supportive care that would confound the interpretation of any 
observed toxicity or side effect is given. Patients must have completed all of the clinical and 
laboratory monitoring requirements specified by the protocol up to the time of disease progression 
for them to be considered evaluable for MTD. Patients receiving less than 85% of planned dosing 
during the dose-finding period for reasons other than toxicity will be considered inevaluable and 
will be replaced. 
 
Patients who do not have DLT and who have completed all therapy during the dose finding period 
but who failed to comply with all the specified clinical and laboratory monitoring requirements 
for the first course may be considered inevaluable for estimating the MTD and replaced. 
 
• Evaluable for Efficacy 
All patients who receive at least 1 dose of the agent will be considered evaluable for efficacy 
analyses and will be assessed based on the tumor response criteria described below.  
 
12.1.1 Disease Parameters 
In order to completely document the assessment of response, the measurements of the longest 
tumor dimension, and its perpendicular, of all target lesions upon which the assessments of tumor 
response are based should be explicitly noted in the radiology report for the baseline and all 
subsequent follow-up exams. Reports for the follow-up exams should reiterate the measurements 
obtained at baseline for each target lesion. Non-target lesions or newly occurring lesions should 
also be enumerated in these reports, and changes in non-target lesions should be described. The 
same method of assessment and the same technique should be used to characterize each identified 
and reported lesion at baseline and during follow-up. 
 
Tumor response criteria are determined by changes in size using the longest tumor dimension and 
its perpendicular. FLAIR, T2 or post contrast T1 weighted images may be used—whichever gives 
the best estimate of tumor size. 
 
Since many tumors contain non-enhancing components (or, in some cases, the tumor may not 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
59 
enhance at all), both the enhancing and the non-enhancing components must be evaluated—on 
post contrast T1 weighted images and on FLAIR/T2 weighted images, respectively. Increase in 
enhancement on T1 weighted images without accompanying increase in disease bulk on T2 or 
FLAIR images is not considered tumor progression. In turn, enlarging areas of non-enhancing 
tumor (defined as mass effect/tissue thickening) are evidence of tumor progression. Conversely, 
decrease in enhancing tumor component without decrease in overall FLAIR/T2 extent may 
represent change in tumor permeability (commonly observed with antiangiogenic therapies) rather 
than represent tumor response. 
 
12.1.2 Method 
The following section describes the methodology. (See Figure 5 for illustration. 
 
• For MRI imaging (preferred), the longest measurement of the tumor (or width, W) should 
be determined. It can be measured from the axial plane or the plane in which the tumor is 
best seen or measured, provided the same plane is used in follow ups. Longest diameter of 
target lesion(s) should be selected in the axial plane only for CT. 
 
• The measurement (transverse (T)) perpendicular to the width in the selected plane should 
be determined. NOTE: A measurable lesion should have a minimal transverse 
measurement that is at least twice the combined thickness of the image slice and the inter-
slice gap. For example, with a 4 mm slice and a 0.4 mm gap, minimal measurable lesion 
diameter is 8.8 mm. Smaller lesions would not be measurable for study purpose. 
 
• Leptomeningeal tumor spread is usually not a target lesion, and usually cannot be measured 
accurately. Presence and location of leptomeningeal tumor spread should be noted and 
changes in extent/thickness assessed on follow up studies.

12.2 
Tumor Response Criteria  
 
12.2.1 Complete Response (CR) 
Complete disappearance on MR of all evaluable tumor and mass effect, on a stable or decreasing 
dose of corticosteroids (or receiving only adrenal replacement doses), accompanied by a stable or 
improving neurologic examination, and maintained for at least 8 weeks. 
 
12.2.2 Partial Response (PR) 
Greater than or equal to 50% reduction in tumor size by bi-dimensional measurement, as compared 
with the baseline measurements, on a stable or decreasing dose of corticosteroids, accompanied 
by a stable or improving neurologic examination, and maintained for at least 8 weeks.  
 
12.2.3 Stable Disease (SD) 
Neurologic exam is at least stable and maintenance corticosteroid dose not increased, and MR 
imaging meets neither the criteria for PR nor the criteria for Progressive Disease. If this category 
is to be reported as of possible clinical benefit, Stable Disease status must be maintained for 8 
weeks.  
 
12.2.4  Progressive Disease (PD) 
Progressive Disease (PD): Progressive neurologic abnormalities or worsening neurologic status 
not explained by causes unrelated to tumor progression (e.g., anticonvulsant or corticosteroid 
toxicity wean, electrolyte disturbances, sepsis, hyperglycemia, etc.), OR a greater than 25% 
increase in the bi-dimensional measurement, taking as a reference the smallest disease 
measurement recorded since the start of protocol therapy, OR the appearance of a new tumor 
lesion.  
 
Increasing doses of corticosteroids required to maintain stable neurological status should be 
strongly considered as a sign of clinical progression unless in the context of recent wean or 
transient neurologic change.  
 
12.2.5 Progression-free Survival (PFS) 
Interval of time between date of initiation of protocol treatment and minimum date of 
documentation of PD, second malignancy, death due to any cause, or date of last follow-up. 
 
12.2.6 Duration of Response 
• Duration of overall response: The duration of overall response is measured from the time 
measurement criteria are met for CR or PR (whichever is first recorded) until the first 
date that recurrent or progressive disease is objectively documented (taking as reference 
for progressive disease the smallest measurements recorded since the treatment started). 
The duration of overall CR is measured from the time measurement criteria are first met 
for CR until the first date that progressive disease is objectively documented.  
 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
61 
• Duration of stable disease: Stable disease is measured from the start of the treatment until 
the criteria for progression are met, taking as reference the smallest measurements 
recorded since the treatment started, including the baseline measurements.

REQUIREMENTS 
Adverse event lists, guidelines, and instructions for AE reporting can be found in Section 10. 
 
13.1 
Study Oversight 
This protocol is monitored at several levels, as described in this section. The Protocol Principal 
Investigator is responsible for monitoring the conduct and progress of the clinical trial, including 
the ongoing review of accrual, patient-specific clinical and laboratory data, and routine and serious 
adverse events; reporting of expedited adverse events; and accumulation of reported adverse 
events from other trials testing the same drug(s). The Protocol Principal Investigator and 
statistician have access to the data at all times.  
 
All Study Investigators at participating sites who register/enroll patients on a given protocol are 
responsible for timely submission of data via Medidata Rave and timely reporting of adverse 
events for that particular study. This includes timely review of data collected on the electronic 
CRFs submitted via Medidata Rave.  
 
All studies are also reviewed in accordance with the Pediatric Brain Tumor Consortium's (PBTC) 
data safety monitoring plan. 
 
13.2 
Data Reporting 
Data collection for this study will be done exclusively through Medidata Rave. Access to the trial 
in Rave is granted through the iMedidata application to all persons with the appropriate roles 
assigned in the Regulatory Support System (RSS). To access Rave via iMedidata, the site user 
must have an active CTEP IAM account (check at https://ctepcore.nci.nih.gov/iam) and the 
appropriate Rave role (Rave CRA, Read-Only, CRA, Lab Admin, SLA, or Site Investigator) on 
either the LPO or participating organization roster at the enrolling site. To the hold Rave CRA role 
or CRA Lab Admin role, the user must hold a minimum of an AP registration type. To hold the 
Rave Site Investigator role, the individual must be registered as an NPIVR or IVR. Associates can 
hold read-only roles in Rave. If the study has a DTL, individuals requiring write access to Rave 
must also be assigned the appropriate Rave tasks on the DTL. 
 
Upon initial site registration approval for the study in RSS, all persons with Rave roles assigned 
on the appropriate roster will be sent a study invitation e-mail from iMedidata. To accept the 
invitation, site users must log into the Select Login (https://login.imedidata.com/selectlogin) using 
their CTEP-IAM username and password, and click on the “accept” link in the upper right-corner

available in the Members’ Area of the PBTC website (http://www.pbtc.org/). 
 
13.2.1 Method 
Required submission of patient demographic data for this study will be submitted automatically 
via OPEN.  
 
Note: Serious adverse events must be submitted via CTEP-AERS per protocol guidelines. 
 
13.3 
Participant and Data Confidentiality 
Participant confidentiality is strictly held in trust by the participating investigators, their staff and 
the sponsor(s) and their agents. This confidentiality is extended to cover testing of biological 
samples and genetic tests in addition to the clinical information relating to participants. Therefore, 
the study protocol, documentation, data and all other information generated will be held in strict 
confidence. No information concerning the study and the data will be released to an unauthorized 
third party without the prior written approval of the Pediatric Brain Tumor Consortium (PBTC).  
 
The PBTC Protocol Coordinators, other authorized representatives of the sponsor, regulatory 
representatives, PBTC auditors, representatives of the IRB or the pharmaceutical collaborator 
supplying study product may inspect all documents and records required to be maintained by the 
investigator, including but not limited to, medical records (office, clinic, or hospital) and pharmacy 
records for the participants in this study. The clinical study site will permit access to such records. 
 
Source documents which are the original records of clinical findings, observations or activities in 
a clinical trial are to be maintained at each participating site. Sites must upload all source 
documentation which supports the eligibility, DLT, or dose finding and evaluability of the 
participant to the PBTC via the RAVE database. In the event the patient experiences unexpected 
events, additional source documentation may be requested to complete the event review. These 
documents may include but are not limited to, hospital records, clinical and office charts, 
laboratory notes, memoranda and radiographic images.  
 
Study participant study related data, which is for purposes of statistical analysis and scientific 
reporting will be transmitted to the Pediatric Brain Tumor Consortium electronically via the RAVE 
database. This will not include the participant's contact or identifying information. Rather, research 
participants and their research data will be identified by a unique study identification number 
assigned at the time of screening or registration. The study participant's contact information will 

NCI Protocol #: PBTC-056 
Version Date: August 8, 2022 
63 
be securely stored at each clinical site for internal use during the study. At the end of the study, all 
records will continue to be kept in a secure location for as long a period as dictated by local IRB 
and institutional regulations. 
 
The study data entry and study management systems used by clinical sites and by the PBTC will 
be secured and password protected. At the end of the study, all study data is maintained on a secure 
server.  
 
After the study is completed, the data collected will be maintained on a server and may be used by 
other investigators, including those outside the study. With the participant's approval and as 
approved by local IRBs, biological samples labeled only with the participant's protocol specific 
identification number will be stored at the PBTC Central Review and Biorepository and could be 
made available to other investigators for future unspecified research. Investigators conducting 
future studies will not have access to the key for stored data collected while the participant is on 
study. Clinical data will be de-identified before it is shared with other investigators.  
 
If the participant agrees to submit a repository sample, those samples contain genetic information 
that may be used for research related to brain tumors and their treatment. They may also be used 
to develop tests/assays to improve diagnosis and treatment of these diseases in the future. Genetic 
research may consist of the analysis of one or more genes or the analysis of genetic markers 
throughout the genome.
