ABSTRACT 
Low grade gliomas are the most common pediatric central nervous system malignancies and can occur 
in different parts of the brain. Patients who undergo gross total resection, usually those with 
hemispheric tumors, have an excellent prognosis with surgical resection alone. Patients for whom gross 
total resection is not achievable have a significant risk of disease progression. Therefore, these patients 
benefit from adjuvant therapy.  Multiple chemotherapy regimens have shown some efficacy in residual 
tumor, but more than 50% of patients experience recurrences. Radiation has been shown to be an 
effective therapy in the treatment of these tumors. Because of concerns regarding radiation toxicity 
especially in young children, and progression despite chemotherapy, novel approaches are needed. This 
protocol represents an attempt to measure the efficacy and safety of use of pegylated interferon for 
patients with recurrent, refractory Juvenile Pilocytic Astrocytomas (JPA) or optic pathway gliomas. It 
provides a different approach to the commonly used treatment modalities. Patients with progressive, 
refractory or symptomatic JPA who have received radiation and who have received at least one prior 
course of chemotherapy will be eligible for this study. All patients on the study will receive a course of 
pegylated interferon 1 mcg/kg/dose weekly lasting for up to 2 years.  Response will be evaluated with 
MRI every 12 weeks. The objectives of this study are to determine the response of children with 
chemotherapy-refractory progressive JPA or optic pathway gliomas (OPG) to weekly pegylated 
interferon alpha-2b.  The secondary objectives include to better identify the toxicities of weekly 
pegylated interferon alpha-2b in pediatric patients with unresectable, refractory, recurrent JPAs or optic 
pathway gliomas, to evaluate various magnetic resonance imaging techniques for noninvasive 
monitoring of metabolic and biologic changes in the tumors and to evaluate the quality of life for 
patients with recurrent, refractory JPAs who receive therapy with pegylated interferon alpha-2b The 
primary end point is to determine the response rate.  The secondary end point is to determine the Event 
Free survival. A two-stage design has been selected to evaluate the response rate. If the treatment 
demonstrates at least a 25% response rate, we would consider it a promising regimen for further study. 
A response rate less than 5% is considered evidence of unpromising regimen. Seventeen evaluable 
pediatric patients with JPA or OPG will be accrued. If at least 3 responders are seen among the 17 
patients, this will be considered evidence of a promising response rate for further evaluation.

2.0 BACKGROUND 
2.1 Introduction/Rationale for Development 
Low-grade gliomas (LGGs) represent the most common pediatric central nervous system (CNS) 
malignancy, accounting for more than half of all such tumors. The most common locations are the 
cerebellum, followed by the cerebral hemispheres and by the deep midline structures such as the 
hypothalamus, thalamus, lateral and 3rd ventricles, and the corpus callosum. These tumors are also 
found along the visual pathways and in the brainstem and in the spinal cord. 
Pediatric LGGs include pilocytic, fibrillary, protoplasmic, gemistocytic, giant-cell astrocytomas, or 
pleomorphic xanthoastrocytoma, oligodendrogliomas and oligoastrocytomas. They belong to the WHO 
classification as grade I and II.  Juvenile Pilocytic Astrocytomas (JPAs) occur predominantly in young 
children and make up the majority of LGGs found along the optic pathway, as dorsally exophytic brain 
stem tumors, and in the cerebellum. Grossly, they appear well circumscribed, and in the cerebellum are 
often cystic, with a mural nodule. They typically, but not always, enhance on MR imaging. JPAs have 
been particularly associated with neurofibromatosis type 1 (NF-1), in this population lesions are mostly 
incidental findings and some of them can have indolent courses and close monitoring with imaging 
studies is  recommended.

Patients with JPA patients who have gross total resection, especially those with tumors located in the 
cerebellar and cerebral hemispheres, have excellent survival at 8 years 99% +/- 0.8% as well as excellent   
event free survival (EFS). From CCG9891 and POG9130, the results of 518 pediatric patients with low 
grade gliomas that only underwent surgical resection and no other treatment modality,   which had 
evidence of residual disease, the EFS at 5 years was 56%.  Patients younger than 5 years of age had 
worse EFS than the older counterpart; however this difference does not   translate into worse overall 
survival. [1]  JPAs that cannot be completely resected, mostly due to location in or near important 
structures, are likely to progress and will require additional therapy.  Effective treatment modalities 
include radiation and chemotherapy. 
Radiation therapy, while effective, has long term effects that can be minimized if the modality can be 
delayed or avoided. 
Merchant conducted a phase II study that included 78 pediatric patients with unresectable low grade 
gliomas who received radiation therapy. The 5 year EFS was 87% +/- 4.4 and 10 year EFS was 74.3% +/- 
15.4%.  The mean and standard error cumulative incidence of vasculopathy was 4.79% +/- 2.73 at 6 
years and it was higher for patients younger than 5 years of age at the time of radiation. The main 
reason to the delay in radiation in young patients with LGG is to reduce their risk of vasculopathy [2]. 
Additionally, patients with LGG after radiation treatment experienced some adverse endocrine events 
that were limited.  The 3 more common hormone replacements were:  growth hormone, thyroid and 
glucocorticoid.  The 5- and 10-year confident intervals for growth hormone replacement were 46.0% +/-
7.2% and 48.9% +/- 7.4%. The thyroid hormone replacement, 61.4% +/-7.5% and 64.0% +/-7.5%.  The 
glucocorticoid replacement was 19.2% +/-5.8% and 19.2% +/-5.8%. Additionally, in the CBCL activities 
scores, for patients with neurofibromatosis -1 who underwent treatment with radiation have a decrease 
in the score from 44.2 to 36.8 after 5 years of treatment, while the average score of a patient without 
NF-1 remained unchanged at 44.2806 despite radiation therapy. [2] 
 
 2.2 Chemotherapy for pediatric low grade gliomas:  
COG 9952 was the first randomized upfront clinical trial for low grade gliomas. It investigated two 
chemotherapy regimens for children less than 10 years with unresected LGGs. Regimen A included 
carboplatin and vincristine (CV). Regimen B included thioguanine, procarbazine, lomustine and 
vincristine (TPCV).  Only regimen A included patients with neurofibromatosis-1. Of 274 randomly 
assigned between both regimens, 137 received regimen A and 137 received regimen B. The 5-year EFS 
and overall survival (OS) rates were 45% ± 3.2% and 86% ± 2.2%, respectively. The 5-year EFS rates were 
39% ± 4% for CV and 52% ± 5% for TPCV ( P = 0.10). Independent factors by multivariate analysis that 
were predictive of worse EFS and OS are younger age and tumor size greater than 3 cm. Additionally, 
the location of the tumor  in the thalamic region was also associated with poor survival. [3]  
Boufet et al conducted a phase II trial with vinblastine for recurrent or refractory pediatric low grade 
glioma dose of 6mg/m2/dose. 36% of patients had complete, partial or minor response. 23/51 patients 
have not had progression. 5 year OS was 93.2% +/- 3/8% and 5 year PFS was 42.3% +/- 7.2%. Vinblastine 
as a weekly regimen was comparable to first line COG 9952. [4]   
The experience of bevacizumab for low grade gliomas is limited to case series. Ten children heavily 
treated for multiply recurrent LGG received the combination of bevacizumab and irinotecan for a 
median of 5.2 years of age, range 1.5-11.1 years. 70% patients had an objective radiographic response (1 
CR, 3 PR and 3 minor Responses). Other clinical improvements were: improved visual acuity, improved 

Protocol Vers   12-14-2018                           11 
 
motor function, weight gain in patients with a diencephalic syndrome, and reversal of psychomotor 
retardation.  Dose-limiting toxicities included transient leukoencephalopathy and grade 3 proteinuria. 
The majority of patients had durable responses.  Six patients remained on treatment for almost 2 years. 
Multiply recurrent low-grade gliomas in children demonstrated responses to the combination of 
bevacizumab and irinotecan.[5, 6]   
A second series reported 7 children who received bevacizumab with irinotecan. Tumor reduction could 
be observed in 6/7 (85%) patients with recurrent low-grade gliomas. Bevacizumab-related acute toxicity 
appears to be low in children, even in combination with irinotecan. [7] 
Finally, 14 pediatric patients with multiply recurrent low-grade gliomas were treated with bevacizumab 
and irinotecan for at least twelve months of follow-up after completion of initial therapy. Median 
treatment duration was 12 months (range, 1 - 24 months). 12/14 patients had an objective response; 
two had stable disease, and no progressions. 13/14 patients progressed after stopping bevacizumab at a 
median of four months. Four patients were retreated with bevacizumab alone and all responded or 
stabilized on treatment. Bevacizumab-based therapy is successful at inducing LGG regression and 
stabilization after initial therapy or with repeated treatment, although nearly all patients' tumors will 
progress off-therapy. Toxicities are not insignificant but usually reversible (6). A subsequent report, gave 
additional details of responses after progression of LGG when retreated with bevacizumab in   4/4 
patients, however alternative dose strategies such as bevacizumab as a single agent and interval does 
every 3 weeks were evaluated. [8] 
Therashima et al evaluated pediatric patients with centrally located LGG who received either chemo or 
radiation to better understanding the risk factors along with the effects of interventions on long-term 
outcome through a retrospective chart review. Forty-seven patients with a median follow-up of 79 
months were included in the analysis. The 5-year EFS and OS were 53% and 96%. The 5-year PFS for 
those that received radiation upfront was 76% vs. those who received chemotherapy as a first line 37%.  
p=0.02. The 5-year PFS after salvage RT was 55% for those who progressed after chemotherapy. [9]  
Pilocytic astrocytomas often have a solid and cystic component at presentation or recurrence. The 
management of the cystic component of the tumor can be difficult when gross total resection is not 
possible. Multiple treatment options are available, including additional resection, fenestration of the 
cyst, and placement of an Ommaya reservoir for intermittent aspiration, systemic chemotherapy, and 
radiation therapy. In a retrospective analysis, the cases of children with pathology confirmed WHO 
grade 1 astrocytomas and identified patients with complications arising from the cystic portion of the 
tumor were reported. 54 patients with tumors with a cystic component. In 31.4% there was progression 
of the cystic portion of the tumor.  The optic pathway/hypothalamus was the most common location for 
progressive tumor cysts.  Surgical resection was attempted in all cases at least once; a total of 39 
surgical procedures were performed. Cyst fenestration was attempted in 35.2%. Ommaya reservoir was 
placed in 47%. 9 patients got external beam radiation and 5/9 (56%) had stabilization of cyst growth 
with no additional therapies.  Intra-cystic administration of P32 was given to only one patient.  
Chemotherapy was used in 65% of cases.  7 of the 11 children who received chemotherapy required 
more than one regimen. This retrospective study shows that management of tumor-associated cysts in 
low grade gliomas remains challenging.  (Wolf D, Cohen KJ, Neuro-oncology  vol 14, 2012,  issue suppl

2.3 Interferon Alpha  
Mechanism of Action:  The interferons (IFN) are a family of glycoproteins with antiproliferative, antiviral, 
and immune-modulating capabilities. Studies have shown that they are involved in control of cell 
function and replication, but their mechanisms of action are not fully known. They bind to cell surface 
receptors, resulting in a signal transduction that induces or suppresses gene expression.  
The interferons induce protein synthesis, inhibit mitotic activity, modify cell membranes and regulate 
immune effector cells. They block cell transition from G0/G1 into the S phase of the cell cycle. They are 
known to suppress the expression of the c-myc and c-fos proto-oncogenes, and receptors for certain 
growth factors. Other  effects of peg interferon alpha-2b include inhibition of viral replication in virus-
infected cells, the suppression of cell cycle progression/cell proliferation, induction of apoptosis, anti-
angiogenic activities, and numerous immunomodulating activities, such as enhancement of the 
phagocytic activity of macrophages, activation of NK cells, stimulation of cytotoxic T-lymphocytes, and 
the upregulation of the Th1 T-helper cell subset.  
Peginterferon raises concentrations of effector proteins such as serum neopterin and 2’5’ 
oligoadenylate synthetase, raises body temperature, and causes reversible decrease in leukocyte and 
platelet counts. 
The type I interferons (IFN-alpha and IFN-beta) are also negative regulators of cell growth and can 
modify cell differentiation. Interferon-alpha can be induced by foreign cells, tumor cells, and virus-
infected cells that stimulate B- lymphocytes, null lymphocytes and macrophages.  
Numerous clinical trials have been performed investigating the utility of interferons for viral diseases 
and cancer. The interferons have been approved by the FDA for several clinical indications, including 
hairy cell leukemia, chronic myelogenous leukemia and melanoma. 
 Interferon therapy has been associated with a variety of side effects including an acute flu-like 
syndrome with malaise, fever and chills, irritability, fatigue and musculoskeletal pain. Longer-term 
effects include depression, anorexia, headache and cognitive impairment. At least some of these effects 
are felt to be dose-related.  
Clinical studies using alpha, beta and gamma interferons have been performed on patients with 
malignant brain tumors using different methods of administration, including intravenous, subcutaneous, 
intramuscular, intrathecal and intracavitary. The results have been mixed. 
 
2.4 Peg-interferon: 
There are 2  brand names of peginterferon alpha 2b on the market, both from the same manufacture.  
-PEG-Intron™(SCHERING-PLOUGH/MERCK) PEG-Intron™is a covalent conjugate of recombinant 
interferon alfa-2b with monomethoxy polyethylene glycol (PEG),  that was FDA-approved in January, 
2001 for use in patients with Hepatitis C.-Sylatron  (SCHERING-PLOUGH/MERCK) is a covalent conjugate 
of recombinant alfa-2b interferon with monomethoxy polyethylene glycol (PEG). The average molecular 
weight of the PEG portion of the molecule is 12,000 daltons. The average molecular weight of the 
SYLATRON molecule is approximately 31,000 daltons. The specific activity of pegylated interferon alfa-2b 
is approximately 0.7 x 108 international units/mg protein.  Initial approval   for the adjuvant treatment of 
melanoma.

Interferon alfa-2b is a water-soluble protein produced by recombinant DNA techniques from the 
bacterial fermentation of an E. Coli strain with a genetically engineered plasmid containing an interferon 
gene from human leukocytes. (package insert)  
Pegylation increases the biologic half-life of the compound, enabling it to be administered once weekly, 
and also reduces the peaks and troughs in blood levels.  Pegylated interferon uses a 12 kilodalton PEG 
that is attached to interferon in a linear fashion.  Maximal serum concentrations occur between 15-44 
hours after dosing, and are sustained for up to 72 hours. The mean elimination half-life is 22-60 hours in 
patients with Hepatitis C virus infection. Renal elimination accounts for 30% of the clearance. Although 
there is extensive data on the use of Pegylated interferon  in adults with hepatitis C and melanoma, 
there is limited data on its use in children or in patients with  other cancers. 
 
2.5 Clinical Data of Interferon in Cancer 
2.5.1 Interferon and Gliomas: In gliomas, Nagai et al  reported a partial response in 2 / 9 patients with 
glioblastoma treated with rIFN-alpha A, and 40% response rate (1 complete response, 7 partial 
responses) in 20 patients with glioblastoma treated with human fibroblast interferon-beta. [10] 
Two phase II trials of temozolomide with interferon alpha-2b (pegylated and non-pegylated) in patients 
with recurrent glioblastoma multiforme demonstrated PFS at 6months was 31% for 29 evaluable 
patients in the IFN study and 38% for 26 evaluable patients in the PEG group. In recurrent GBM patients, 
in combination with both studies of standard dose TMZ with either IFN or PEG showed improved 
efficacy when compared to reports using TMZ alone. The grade 3 or 4 toxicities more common were 
leucopenia and thrombocytopenia. Grade 3 or 4 fatigue occurred in 18% of patients on both studies. 
Lymphopenia was not seen frequently. [11]  
In a pediatric study involving children with recurrent malignant tumors treated with recombinant 
interferon-ß, 2 of 9 children with brainstem gliomas had a partial response (>50% reduction in tumor 
size) and 2 children had prolonged disease stabilization (1 child for 3.5 years).[12] 
 In a follow-up study of pediatric patients with brainstem gliomas treated with IV recombinant ß-
interferon during hyperfractionated radiation therapy, 13 of 32 patients required dose modifications 
due to hepatic or hematologic toxicity. [13] 
The optimal dosing for interferon alpha has not yet been established, although it has been used to treat 
a variety of neoplasms. It has traditionally been administered in high doses = 3,000,000 U/m2, 2-
3x/week. Significant side effects have limited its use.  
In one study in which interferon alpha-2a was administered to pediatric patients with recurrent or 
progressive craniopharyngiomas at a dose of 8,000,000 U/m2 daily for 16 weeks, followed by the same 
dose 3 times a week for an additional 32 weeks, the need for radiation therapy was significantly delayed 
in 6 of 15 patients, but more than 50% of the patients experienced significant toxicity requiring 
intervention or dose reduction within the first 8 weeks of therapy. [14]

2.6 Pegylated interferon in  Clinical Studies and Case Series  
-Pegylated interferon in Children with Diffuse Intrinsic Pontine Gliomas:  Warren et al conducted phase II 
trial of Pegylated interferon for children with diffuse intrinsic pontine glioma (DIPG). Pegylated 
interferon was administered as a low-dose of 0.3 μg/kg continuous exposure beginning 2 to 10 weeks 
after the completion of radiation therapy until they developed disease progression. Thirty-two patients 
(median age, 5.3 years; range, 1.8-14.8 years) received a median of 7 cycles of therapy. PEGylated 
interferon was well tolerated. The 2-year survival rate was not significantly improved compared with the 
historic cohort. The median time to progression was 7.8 months. DIPG compared with an historic control 
population, it did delay the time to progression. The scientific reason for the low dose of interferon was 
the anti-angiogenic affect seen in animal models. [15]  
-Pegylated interferon in Children with Cystic Craniopharyngiomas: 
In a different type of brain tumor, however it carries similarities to LGG since both can have cystic 
components, the use of Pegylated interferon has been described. Recently, a case series of 5 children 
with recurrent craniopharyngiomas treated with Pegylated interferon-alpha-2b was published. Their age 
ranged from 9 to 15 years treated for up to 2 years with subcutaneous injections of Pegylated interferon 
at a dose of 1-3 μg/kg/week. Tumor response was assessed using MRIs. All 5 patients had stable disease 
or responses to the Pegylater interferon. One patient experienced increase in the predominantly cystic 
tumor after 3 months of treatment, followed by a complete response with no recurrence for greater 
than 10 years.  Another patient had complete disappearance of the predominantly cystic component 
after 4 months of treatment, and a small residual calcified mass remains 5 years later. The third patient 
experienced a complete response after 7 months of treatment and remains without disease 19 months 
after starting treatment. The fourth patient experienced a 30% decrease in tumor size after 4 months of 
treatment, which was maintained for 12 months at which point the cyst began to increase in size. The 
final patient had stable disease 6 months after starting treatment. These case series are the basis for a 
clinical trial for recurrent craniopharyngiomas to evaluate the response to Pegylated interferon. Based 
on the responses, it could be possible to potentially delay or avoid the need for radiation therapy in the 
future. [16]  
 
-Pegylated interferon in Children with Progressive Neurofibromas:  The safety and tolerability of 
pegylated interferon was evaluated in a phase I trial in patients unresectable progressive or 
symptomatic plexiform neurofibromas (PN).Thirty patients (median age 9.3 years) were treated. All 5 
patients at the 4.5 μg/kg DL came off study or required dose reductions for behavioral toxicity or 
fatigue.  During the first 4 weeks, no dose-limiting toxicity (DLT) was seen in patients treated at the 3 
μg/kg dose level (DL), however similar DLT on the 3 μg/kg DL became apparent over time. At the 1.0 
μg/kg DL, there was 1 DLT (myoclonus) in 12 patients enrolled.  11/16 patients had pain improvement 
and 13/14 patients had a decrease in size of a palpable mass. Volumetric analysis had a 15%-22% 
decrease in volume in 5/ 17 patients (29%).  The dose recommended for phase II of pegylated interferon 
for pediatric patients is 1 μg/kg/wk.  This trial is currently ongoing.[17] (www.clinicaltrials.gov)

2.7 Dose and Schedule  
The type I interferons down-regulate the expression of pro-angiogenic molecules, including bFGF, IL-8, 
MMP-2 and MMP-9. Systemic chronic administration of IFN-a or IFN-ß has been shown to produce 
regression of vascular tumors by down-regulation of mRNA expression and protein production of the 
angiogenic factor, bFGF23.  
This effect requires long term exposure to IFNs, as has been demonstrated clinically and in vitro. 
Through in vitro and animal model, Slaton et.al have demonstrated that daily administration of 
interferon alpha-2a, at doses far below maximally tolerated doses, produced the most significant 
inhibition of tumor growth, tumor vascularization, and maximal inhibition of angiogenesis-regulating 
genes.   His experiments demonstrated that when human bladder cancer cell lines were implanted into 
the bladder of mice and the mice were injected subcutaneously daily, 1x/ week or 2x/ week for 4 weeks 
with interferon alfa-2a. Examination and evaluation after 4 weeks demonstrated that interferon alfa-2a 
administered daily produced superior anti-proliferative and anti-angiogenic activities compared to an 
equivalent weekly dose administered 1, 2 or 3 X/week.  
In a comparison of escalating daily doses of interferon alfa-2-a (2500-50,000 units/dose), maximal 
inhibition occurred at a dose of 5000 or 10,000 units/day. Administration of higher doses failed to 
produce significant anti-angiogenic effects. [18] 
 
2.7.1 Doses for Pegylated interferon  
-For patients with chronic hepatitis as a monotherapy the dose is 1 mcg/kg/Week SC x1 year. 
-For patients with melanoma with microscopic or gross nodal involvement within 84 days of definitive 
surgical resection including complete lymphadenectomy, the doses used are 6mcg/kg/week 
subcutaneous for 8 doses, then 3 mcg/kg/week SC for up to 5 yr.  Rotating the injection sites. 
-Phase I study in patients with neurofibromatosis related plexiform neurofibromas had a recommended 
dose for phase II of   1mcg/kg/week. [17] 
-The doses used for the patients treated in the series with recurrent craniopharyngioma ranged from 1 
to 3 mcg/kg/dose.  
-For this trial, the dose is 1 mcg/kg/dose. There are specific criteria for reduction of the dose based on 
toxicity. Two dose modifications have been permitted.

2.8 Imaging   
Imaging of the tumor will be assessed with MRI of brain and /or spine with and without contrast 
performed on a 1.5 or 3T scanner. Progressive disease will be defined on the basis of a comparison of 
the baseline scan to the scan demonstrating best response. All axial images should be obtained in a 
plane parallel to a line intersecting the bottom of the genu and of the splenium of the corpus callosum 
to assure consistency of imaging plane. Coronal images should be obtained in a plane perpendicular to 
the axial images. 
1) Axial diffusion tensor imaging whole brain 
2) Sagittal, volumetric T1-weighted, gradient echo whole head 
3) Axial T2-weighted fast spin echo (FSE) whole head 
4) 3D Coronal FLAIR. 
5) Coronal T2-weighted fast spin echo (FSE), fat saturated through the orbits and chiasm. 
6) Axial T2-weighted fast spin echo (FSE), fat saturated through the orbits and chiasm. 
7) Axial volumetric T1-weighted gradient echo post contrast whole brain. 
8) Axial Oblique T1-weighted Fat Suppressed gradient echo post contrast, optic nerves and chiasm. 
9) Coronal T1-weighted Fat suppressed gradient echo post contrast, optic nerves and chiasm. If imaging 
of the spine is needed, axial and sagittal T2 and post contrast T1 weighted images will be acquired. 
Diffusion images of the spine will be obtained if clinically indicated. Volumetric studies for MRI of the 
brain will be obtain to better evaluate the cystic component of the 
Low grade gliomas and be able to evaluate responses to the therapy.   
These sequences are the minimum required to evaluate the response to the treatment.  Additional 
sequences such as MR spectroscopy can be obtained if clinically indicated per institutional protocols.

4.0 TREATMENT PROGRAM 
Timing of protocol therapy administration, response assessment studies, and surgical interventions are 
based on schedules derived from the experimental design or on established standards of care. Minor 
unavoidable departures (+/- up to 5 days) from protocol directed therapy (and up to 1 week for surgery) 
and/or disease evaluations for valid clinical, patient and family logistical, or facility, procedure and/or 
anesthesia scheduling issues are acceptable. If an unavoidable departure occurs, patients should 
continue to follow the roadmap and diary and get assessments within the 5 day  period, with the 
exception of course 1. 
 
4.1 Overview of the treatment plan 
Treatment with pegylated interferon alpha-2b must begin within 14 days of patient enrollment. Patients 
may be pre-medicated as needed with acetaminophen 10-15 mg/kg (maximum 650 mg per dose) or 
ibuprofen 10 mg/kg within 1 hour of receiving Pegylated interferon. The patients can continue on either 
acetaminophen or ibuprofen for up to 48 hours after Pegylated interferon injection. The maximum dose 
of ibuprofen in a 24-hour period will be 40 mg/kg.  Ibuprofen for Adolescents and Adults the maximum 
daily dose: 2.4 grams in 24 hours.  Premedication is optional. 
Each cycle of therapy will consist of pegylated interferon alfa-2b administered subcutaneously once 
weekly (+/- 5days) for 4 weeks for up to 2 years. Each dose should be administered on the same day 

Protocol Vers   12-14-2018                           23 
 
each week. There will be no breaks between cycles. Total number of cycles 26. Each dose is 1µg/kg 
subcutaneously. Nursing staff will instruct the patients or their caregivers regarding sites of injection and 
injection technique.  Teaching needs to be documented.  Rotating the sites of injection is strongly 
recommended.  
Patients and/or their caregivers will be asked to maintain a diary (Appendix 5) documenting the dose of 
pegylated interferon alpha-2b given, site of administration and any side effects. This diary will be 
reviewed at each clinic visit.  Patients will return to the Aflac clinic prior to start next cycles.  
Doses could be rounded up to the nearest upper 5mcg for easier administration. For patients whose 
weight is greater than 150kg the maximum dose of Pegylated interferon to be administered is 
150mcg/dose/ week. 
MRI brain and /or spine will be performed as a baseline within 30 days of enrollment and subsequently 
every 3 cycles.  
 
See section 7.1 for required observations prior to start therapy.  
 
4.2 Concomitant therapy restrictions 
 
4.2.1 
Concurrent cancer therapy, including chemotherapy, radiation therapy, immunotherapy, or biologic 
therapy   can NOT be administered to patients while on this study. The use of alternative or 
complementary therapies is discouraged. 
 
4.2.2 
Radiotherapy is not permitted. 
 
4.2.3 
Filgrastim (G-CSF) may be used at the treating physician’s discretion in patients with severe neutropenia 
(i.e. ANC <500/μL) to enhance neutrophil recovery when clinically indicated (for culture proven 
bacteremia or invasive fungal infections). Prophylactic or routine use of filgrastim in clinically well 
patients awaiting count recovery is not recommended. 
 
4.2.4 
Corticosteroid therapy is permissible only for the treatment of increased intracranial pressure or 
physiologic replacement. The lowest dose consistent with good medical management should be used. 
Corticosteroids should NOT be used as an antiemetic due to their effect on the blood brain barrier. 
Patients on steroids who require an increase in steroid dose for worsening neurologic symptoms should 
have an MRI performed within 5 days to rule out tumor progression. 
 
4.2.5 
Appropriate antibiotics, blood products, anti-emetics, fluids, electrolytes and general supportive care 
are to be used as necessary.  PCP prophylaxis is recommended following the institutional guidelines 
when absolute lymphocyte count is below 1200.

Anticonvulsants may be administered as clinically indicated. However, it is recommended to avoid 
enzyme inducing anticonvulsants.  
 
For Supportive Care Guidelines  use Children's Oncology group  guidelines, see: 
https://members.childrensoncologygroup.org/prot/reference_materials.asp under Standard Sections 
for Protocols. 
 
4.3 Pegylated interferon Administration 
 
Pegylated interferon will be administered weekly (+/- 5 days) at a dose of 1mcg/kg/dose via 
subcutaneous injection, approximately at the same time every week.   
It is important to rotate the injection sites.  Teaching will be done to the parents/guardian/patient   in 
the first and/or second injection so the family will learn the technique and can continue to do it at 
home. Family/guardian will be provided with diaries to document compliance and   side effects.  
Patients may be pre-medicated with acetaminophen or ibuprofen. Specifically, patients can receive 
acetaminophen 10-15 mg/kg (maximum 650 mg per dose, maximum dose 4 grams/24 hours) or 
ibuprofen 10 mg/kg within 1 hour prior to receiving PEPegylated interferon. The patients can continue 
on either acetaminophen or ibuprofen for up to 48 hours after the pegylated interferon injection as 
needed. The maximum dose of ibuprofen in a 24-hour period will be 40 mg/kg or patients with weight 
for more than 45 kg is 2.4 grams/24 hours. Premedication is optional. 
Pegylated interferon will begin a Cycle on Day 1 if ANC ≥ 1,000/μL, platelet count ≥ 100,000/μL 
(transfusion independent). 
Dose calculations should be based on actual weight and adjusted as necessary prior to each cycle.  
The maximum dose is 150 mcg. 
Note: The calculated dose should be rounded to the nearest highest 5mcg of the prescribed dose for 
convenience of administration. Each cycle is 28 days.  The total duration of the trial is 2 years a total of 
26 cycles.  
See Section 5.0 for   Dose Modifications Based on Toxicities. 
 
The therapy delivery maps (TDMs) for this cycle are on the next pages 
 
Following completion of the first cycle, the Pegylated interferon cycle is repeated weekly for up to a 
total of 26 cycles, as tolerated and in the absence of disease progression (see Section 10.4 for Response 
Evaluation).  If disease progression occurs, the patient will be taken off protocol therapy. 
Subsequent Pegylated interferon cycles should begin on Day 29 or when ANC ≥ 1,000/μL, platelet count 
≥ 100,000/μL (transfusion independent), whichever occurs later.

4.4 Criteria for Starting Subsequent Courses of Treatment 
A course may be repeated every 28 days, up to a total of 2 years if the patient has at least stable disease 
and has again met laboratory parameters. 
Patients who complete a treatment cycle may receive another cycle if:  
• 
Disease Status: the patient has no evidence of progressive disease or in the opinion of the 
investigator, the patient is benefiting from the therapy with pegylated interferon alfa-2b ) as 
evidenced by a decrease in tumor-related symptoms.  
• 
Toxicity: the patient has not experienced any toxicity that meets off-study  criteria as described in 
Section 5.0 
• 
Patients will not be allowed to have a dose escalation after dose reduction due to toxicity. 
 
5.0 DOSE MODIFICATIONS FOR TOXICITY  
 
For patients who are unable to tolerate the protocol-specified dosing schedule, dose adjustments are 
permitted in order to keep the patient on study drug. If administration of Pegylated interferon must be 
interrupted because of unacceptable toxicity, drug dosing will be interrupted or modified according to 
rules described below. Toxicity will be assessed using the NIH-NCI Common Terminology Criteria for 
Adverse Events, version 5.0 
 
https://ctep.cancer.gov/protocoldevelopment/electronic_applications/docs/CTCAE_v5_Quick_Referenc
e_5x7.pdf 
 
Pegylated interferon dose level modification guidelines 
 
Patients who experience significant toxicity as listed in section 5.0 will have the dose reduced by  25% of 
the dose on subsequent cycles.  Two dose reductions are allowed, as long as there is no evidence of 
progressive disease (see section 10.4) Patients who again experience dose modifying toxicity after 2 
dose reductions will be taken off protocol therapy.  
 
Dose Modification for Toxicity 
Dose and schedule 
 
Standard dose 
1mcg/kg/dose 
Dose Modifications 
First Dose Modification: reduction by 25% of dose 
 
Second Dose Modification: reduction by 50% of 
dose 
 
Permanently discontinue if unable to tolerate  
second dose modification 
*For patients whose weight is greater than 150kg, the maximum dose of Pegylated interferon to be 
administered is 150mcg/dose/week.   (See table above)  
5.1  Non-hematological  Toxicities 
The dose of Pegylated interferon will be reduced for any of the following toxicities at least possibly 
attributed to Pegylated interferon 
• Any Grade 4 non-hematological toxicity 
• Any Grade 3 non-hematological toxicity with the specific exclusion of: 

Protocol Vers   12-14-2018                           30 
 
- Grade 3 nausea and vomiting controlled by antiemetics 
- Grade 3 fever or infection 
- Grade 3 fever, myalgias, arthralgias, and rigors. 
- Grade 3 hypophosphatemia, hypokalemia, hypocalcemia or hypomagnesemia responsive to 
oral supplementation. 
 
• Any Grade 2 non-hematologic toxicity that persists for > 3 days and is considered sufficiently medically 
significant or sufficiently intolerable by patients that it requires treatment interruption 
 
• Any other adverse event attributed to Pegylated interferon that requires treatment interruption for > 
3 days or which recurs upon drug re-challenge and requires treatment interruption. 
 
• Non-hematological toxicity that causes a delay of more than 14 days between treatment cycles. 
 
Patients who experience non-hematologic toxicity should have appropriate laboratory testing at least 
weekly until the toxicity has resolved. 
 
If the toxicity does not return to less or equal than Grade 1 within 14 days, the patient will no longer be 
eligible to receive treatment on this study.  
If the toxicity returns to less or equal to Grade 1 within 14 days, the patient may restart the study drug 
at initial dose modification once weekly and remain at that dose.  
If the same Grade 3 or 4 non-hematologic toxicity recurs, hold drug and wait until toxicity returns to less 
or equal to Grade 1. If toxicity returns to less or equal to grade 1 within 14 days, the patient may restart 
the study drug at second dose modification and remain at that dose. If the toxicity does not return to 
less than Grade 1 within 14 days, the patient will no longer be eligible to receive treatment on this 
study.  
If the same Grade 3 or 4 non-hematological toxicity recurs and it is felt to be due to the study drug, the 
patient will no longer be eligible to receive pegylated interferon alfa-2b. 
5.2 Hematologic Toxicity 
The dose of Pegylated interferon will be reduced for any of the following toxicities: 
• Grade 4 decreased neutrophil count (neutropenia) > 5 days duration 
• Grade 4 decreased platelet count (thrombocytopenia) > 5 days duration 
• ≥ 2 platelet transfusions per cycle for platelet counts < 30,000/μL 
• ≥ 14 day delay in starting subsequent cycles due to low ANC (< 1,000/μL or low platelet count (less 
than 100,000/μL.) 
Patients who experience hematologic toxicity should have appropriate laboratory testing at least weekly 
until the toxicity has resolved.

Drug Interactions (Package Insert).  
Drugs Metabolized by Cytochrome P-450:  When administering Pegylated interferon with medications 
metabolized by CYP2C8/9 (e.g., warfarin and phenytoin) or CYP2D6 (e.g., ondansetron, flecainide), the 
therapeutic effect of these substrates may be decreased. 
Methadone:  Pegylated interferon may increase methadone concentrations.  The clinical significance of 
this finding is unknown; however, patients should be monitored for signs and symptoms of increased 
narcotic effect. 
7.0 EVALUATIONS/MATERIAL AND DATA TO BE ACCESSIONED 
Timing of protocol therapy administration, response assessment studies, and surgical interventions are 
based on schedules derived from the experimental design or on established standards of care. Minor 
unavoidable departures (up to 96 hours) from protocol directed therapy and/or disease evaluations (and 
up to 1 week for surgery) for valid clinical, patient and family logistical, or facility, procedure and/or 
anesthesia scheduling issues are acceptable.

2-Required for all females of childbearing potential as a baseline study, then continue to follow 
institutional guidelines regarding pregnancy testing.   
3- With and without contrast; within 30 days prior to enrollment. 
4-For patients with a known history of spinal disease, within 30 days  prior to enrollment on the study or 
when it is clinically indicated by the treating physician. 
5-If no > Grade I toxicity during the previous cycle, then every month in subsequent cycles through cycle 
27.

6-For patients with history of spinal disease; obtained at the same time points as MRI brain until no 
evidence of disease on 2 consecutive spine MRIs. Also when patient is removed from protocol therapy.  
7-Opthalmology evaluation only needed for patients with optic pathway gliomas. (Sooner than interval 
designated if indicated by neuro-opthalmologist/opthalmologist) 
8- Children   younger than 7 years and older will complete the parent survey only. For any child older 
than 7 years will complete also the patient questionnaire for Quality of life. QOL questionnaires are only 
available for English speaking patients. They have not been validated in other languages.  
9- LP only if there is evidence of tumor dissemination on spine MRI.  
10-Repeat only if cytology showed tumor cells at study entry, until you have 2 consecutive negative 
cytologies.  
** To be completed when patient comes off therapy unless it has been completed within the last 14 
days and no toxicity greater than grade 1 was found.   
This table only includes evaluations necessary to answer the primary and secondary aims. Obtain 
other studies as indicated for good clinical care. 
 
History and Physical Examination: This should include signs and symptoms caused by the tumor/cancer, 
and determination of performance status or Lanski score.  Patients must have a baseline neurological 
exam and neurological exam at the start of each new cycle. Weight, height and VS must be recorded.  
Laboratory Evaluation: 
-Hematology: Complete blood count, differential and platelet count every 2 weeks during the first cycle. 
If the patient does not experience any >Grade 1 hematologic toxicity during the first cycle, a CBC can be 
performed every 4 weeks on subsequent  cycles, and as clinically indicated. If a patient experiences 
>Grade 1 hematologic toxicity (except for lymphopenia), they will continue to have weekly lab work until 
they have a cycle with no >Grade 1 toxicity. Following that cycle the lab work will be performed every 4 
weeks (+/- 5 days) and as clinically indicated until completion of therapy. If the patient remains on-study 
beyond this and is hematologically stable, the patient will require lab work prior to every cycle as long as 
there is no >Grade 1 hematologic toxicity.  
-Chemistries: CMP, magnesium, phosphorous, calcium and uric acid every other week during the first 
cycle. If the patient does not experience any >Grade 1 laboratory toxicity on the first cycle which is 
possibly, probably, or definitely related to Pegylated interferon, these can be performed every month on 
subsequent cycles, and as clinically indicated. If a patient experiences >Grade 1 laboratory toxicity they 
will continue to have weekly lab work until they have a cycle with no >Grade 1 toxicity. Following that 
cycle the lab work will be performed every 4 weeks and as clinically indicated until end of therapy.  
If the patient remains on-study beyond this, the patient will require lab work prior to every cycle as long 
as there are no >Grade 1 laboratory toxicities.  
-Calcium, phosphorous, magnesium and uric acid will be performed prior to each cycle and as clinically 
indicated.  
-PT and PTT will be obtained at a baseline. Obtain later on only if clinically indicated.  

Protocol Vers   12-14-2018                           36 
 
-Endocrine Function Tests: First morning cortisol, free T4, TSH every six months or sooner if clinically 
indicated.   Growth hormone testing to be done if clinically indicated. 
-Urinalysis or urine dipstick is acceptable.  Urinalysis will be obtained if urine dipstick is abnormal. If

9.0 STATISTICAL CONSIDERATIONS 
 
9.1  Sample Size and Study Duration 
This study will enroll patient without NF-1 and patients with NF-1. Based on the established accrual 
goals and incidence of pediatric low grade gliomas 17 patients can be accrued within 36 months of 
protocol activation, given an average of 1 patient per 2.1 months.  Assuming 15% of patients are not 
evaluable or eligible, 20 patients total will be required to be enrolled on this study.  
 
9.2 Study Design 
The study is designed using Simon’s two stage optimal design with a power of 80% and an alpha error of 
5%. We assume an uninterested response rate of 5% and the promising response rate is 25%.In the first 
stage of the study, 9 eligible patients will be enrolled. If none responder among the 9 patients, the study 
terminates and treatment will be determined to have no improvement in the response rate. Otherwise, 
the study will continue with the second stage in which 8 additional eligible patients will be enrolled for a 
total of 17 eligible patients. At the end of total patient accrual, at least 3 of 17 eligible patients must 

Protocol Vers   12-14-2018                           38 
 
achieve response in order to consider the treatment interesting for further evaluation. Response is 
considered as either CR or PR or SD.

9.3 Methods of Analysis: 
 
9.3.1 End Points 
9.3.1.1          Primary End points: 
• 
Objective response: best response determined from the sequence of objective status 
described in the section 10 as response criteria.  
 
9.3.1.2          Secondary End Points 
• 
Time to treatment failure (Event free Survival EFS) the time from study enrollment to 
tumor progression, tumor recurrence, death from any cause or occurrence of a second 
malignant neoplasm. 
• 
Time to death (Overall survival OS) the time from study enrollment to death from any  
cause.  
 
9.4   Analysis  of  Efficacy 
 
Each patient will be classified according to their ‘best response’ for the purposes of analysis of 
treatment effect. A responder is defined as a patient who achieves a best overall response of CR or PR at 
any time on the study. If a patient achieves a PR or CR and later has progressive disease or relapse, then 
the patient will be counted as a responder. The response rate will be calculated as the ratio of the 
number of patients who demonstrate response (CR or PR) divided by the number of patients evaluable 
for response. All patients eligible for study who receive any study drug will be considered evaluable for 
response. Any patient who goes off protocol therapy for any reason (patient/parent/physician choice, 
adverse event profile, etc.) prior to the first response evaluation will be considered a non-responder.  
Disease progression will be based on the results of institutional review. Standard survival methods will 
be used for analysis of EFS and OS. Analyses include log rank tests and the product-limit (Kaplan-Meier) 
estimate for estimation of EFS and OS probability. 
 
 
9.5  Monitoring for Efficacy 
Patients will be treated with Pegylated interferon on a single arm.  We will closely monitor the first 9 
patients enrolled. The early stopping criterion and the decision regarding ultimate further interest in this 

Protocol Vers   12-14-2018                           39 
 
agent will be based on the number of objective responses and disease progressions.  If the early 
stopping rule is met for no responses in the first 9 patients, the trial will be closed.   
A true response rate of 5% is considered inadequate, whereas a true response rate of 25% would be 
sufficient for further interest in this agent. 
The study will be a 2-stage design, with 9 evaluable patients in the first stage and 8 additional  evaluable 
patients in the second stage (17 patients total) with decisions made as follows: 
 
Number of Evaluable Patients  
Results 
Decision  
 
Stage One:  
9 evaluable patients  
zero responders  
Terminate enrollment with the  
conclusion the regimen does not  
demonstrate sufficient disease 
control 
 
Stage Two 
8 evaluable patients  
3 responders 
Complete  the trial  with the   
conclusion the regimen does  
demonstrate sufficient disease 
control to proceed with further 
development. 
 
9.6   Monitoring for Toxicity 
“Toxic events” will be defined as one in which a patient has two dose reductions and then experiences 
another significant toxicity as defined in Section 5.0, irrespective of attribution. A two-stage stopping 
rule will be used to monitor for an excessive number of these toxic events. All patients described below 
must be evaluable for toxicity. All patients who receive at least one dose of Pegylated interferon will be 
evaluable for toxicity. A review of treatment feasibility and patient safety will be undertaken if we 
observe at least 2/9 or 4/17 toxic events. The rule will be met about 4% of the time if the true incidence 
of toxic event is 10%, and 90% of the time if the true incidence is 30%. 
 
9.7   Interim Monitoring of Toxic Death 
Toxic death is death predominantly attributable to treatment-related causes. The occurrence of toxic 
death at any time will be a primary endpoint for safety monitoring. Any toxic death on study will be 
reviewed with DSMB prior to continuing enrollment on study. The study will be stopped if there is one 
toxic deaths on study. 
 
9.8  Analysis of Toxicity 
Estimates will be obtained using life-table methods, with an event defined as the first occurrence of a 
primary toxicity. Time scale used in the time to first occurrence of a key acute and subacute toxicity is 
time in days since the start of therapy. Patients who have progression or recurrence of disease will be 
censored in these analyses. The rates of individual toxicities in each course of treatment, the number of 
patients who require a dose reduction and number of patients who come off protocol therapy due to 
toxicity will be summarized using standard descriptive statistical methods. To evaluate hematologic 
toxicity of long term Pegylated interferon administration adverse event data will be collected using 
CTCAE version 5.0 toxicity coding. Grade 3 or greater hematologic toxicities will be recorded per 
reporting period. 
 
9.9 Subject Accrual  

Protocol Vers   12-14-2018                           40 
 
Subjects of both genders, from all racial and ethnic groups are eligible for this study if they meet the 
criteria outlined in Section 3.2. To date, there is no information that suggests differences in drug 
metabolism or disease response would be expected in one group compared to another. Efforts will be 
made to extend this accrual to a representative population, but in this study, a balance must be struck 
between patient safety considerations and limitations on the number of individuals exposed to 
potentially ineffective treatments on the one hand and the need to explore gender and ethnic aspects of 
clinical research on the other hand. If differences in outcome that correlates to gender or to ethnic 
identity are noted, accrual may be expanded or additional studies may be performed to investigate 
those differences more fully.  
 
9.10 Radiographic Evaluation 
MRI of brain with and without contrast must be performed within 30 days prior to enrollment on the 
study. Patients will undergo baseline and follow-up imaging in the same scanner if possible. All patients 
will receive a standard MRI, unless contraindicated, performed on either the 1.5T or 3T scanner. (If MRI 
is contraindicated, patient cannot be enrolled). Patients undergoing MRI may also undergo additional 
MR sequences such as dynamic contrast-enhanced (DCE) or MRI, dynamic susceptibility contrast (DSC) 
MRI as time permits. These sequences are part of standard brain tumor protocols. Percent agreement 
between the sequences will be estimated as the number of follow-up scans in which the corresponding 
sequence agreed divided by the total number of follow-up scans. Standard error will be estimated by 
use of the bootstrap method 26 to account for the correlated dependent response data, and these 
values will be used to estimate the 95% confidence intervals. The event-free survival distributions will be 
compared across the MR sequences, with a proportional hazards model developed for dependent 
survival data by Wei et al (1989). 
 
9.11 Ethical Issues  
Rationale for Subject Selection: Subject accrual for the study is available to both genders, racial and 
ethnic groups.  No groups are being excluded from participation in the trial. Some of the subjects could 
become cognitively impaired as a consequence of, for example, their brain tumor. Patients who are 18 
years old or older will be offered the opportunity to assign DPA prior to study entry. Adults who are 
cognitively impaired prior to study entry and who have not previously assigned DPA to a family member 
or friend will not be eligible for the trial, because they cannot give informed consent.  
9.12  Participation of Children   
Patients <21 years of age will be entered on this protocol. The primary objective of this trial is to 
determine if there is evidence of responses for patients receiving Pegylated interferon. The interferons 
have been extensively studied in both adults and children, and the side effects are well-described. 
Although pegylated interferon alpha-2b has not been extensively studied in children, we will use doses 
of interferon alpha-2b previously utilized in clinical trials, therefore we expect to see similar toxicity and 
similar side effects.  The trial will be conducted by pediatric oncologists who have extensive experience 
in performing investigational drug trials in children. Patients will be cared for in the Aflac Cancer and 
Blood Disorder Center. 
9.13  Risks and Benefits  

Protocol Vers   12-14-2018                           41 
 
Patients eligible for this trial are less than 21 years old. The primary risk to patients participating in this 
research study is from toxicity of pegylated interferon alfa-2b The protocol provides for detailed and 
careful monitoring of all patients to assess for toxicity. Patients will be treated with therapeutic intent 
and response to the therapy will be closely monitored. Patients will also be at risk from the MRI contrast 
agent, Gd-DTPA ( gadolinium). The risks of Gd-DTPA are well-defined and consist primarily of nausea. 
Allergic reactions are rare. The potential benefits from pegylated interferon alpha-2b are disease 
stabilization or shrinkage, a reduction in symptoms caused by the tumor/cancer, and prolonged survival 
and the potential to avoid and or delay radiation. Therefore, this protocol involves greater than minimal 
risk to children, but presents the potential for direct benefit to individual subjects.  
 
 
10.0 EVALUATION CRITERIA 
 
10.1 Common Terminology Criteria for Adverse Events (CTCAE) 
This study will utilize version 5.0 of the CTCAE of the National Cancer Institute (NCI) for toxicity and 
performance reporting. A copy of the CTCAE version 5.0 can be downloaded from the CTEP website 
 
https://ctep.cancer.gov/protocoldevelopment/electronic_applications/docs/CTCAE_v5_Quick_Referenc
e_5x7.pdf 
 
Please note: ‘CTCAE v5.0’ is understood to represent the most current version of CTCAE v5.0 as 
referenced on the CTEP website  
 
10.2 Methodology to Determine Tumor Measurement 
All axial images should be obtained in a plane parallel to a line intersecting the bottom of the genu and 
of the splenium of the corpus callosum (modified AC-PC line) - to assure consistency of imaging plane. 
Coronal images should be obtained perpendicular to the axial images. 
 
1) DAx TI, whole brain, 12 directions.2) Sagittal T1 weighted MP_RAGE (TR/TI 2300/900) 
3 Ax T2 weighted  (TR ~4500, TE ~75) 
4) 3D Coronal FLAIR (TR/TI 4800/1650) 
5 Coronal 2D, fat saturated TSE through the orbits and chiasm (TR ~3,500, Te ~80) 
6 Axial 2d, fat saturated TSE through the orbits and chiasm (TR ~3,500, Te ~80) 
Post-Contrast 
7) Axial, whole brain SPGR (TR/TE ~) 
8) Coronal 2d, fat saturated TSE through the orbits and chiasm (TR ~3,500, Te ~80) 
9) Axial 2d, fat saturated TSE through the orbits and chiasm (TR ~3,500, Te ~80) 
 
Series 5 and 8 should have the same slice locations. 
Series 6 and 9 should have the same slice locations. 
 
  
10.3   Tumor measurement 
Given the complexity of JPA/ OPG, the tumor size/response will be assessed in different segments: 
1. Optic nerve (right, left) 

Protocol Vers   12-14-2018                           42 
 
2. Chiasm /hypothalamus 
3. Brain parenchyma / retrochiasmatic visual pathways (optic tracts, optic radiations, internal capsule, 
posterior fossa) (right/left). 
 
Therefore, up to 5 measurements may be necessary. 
1. Longest diameter of target lesion(s) measured from the axial plane or the plane in which the aspect of 
the tumor is best seen or measured, provided the same plane is used in follow ups. 
 
2. The longest measurement of the tumor (or width, W) should be determined. 
 
3. The perpendicular measurements (transverse (T) measurement-perpendicular to the width in the 
selected plane. The length (L) – tumor extent in the plane perpendicular to the selected plane will not be 
used for measurement purpose. 
 
4. The lower limit of the target lesion(s) should be at least twice the thickness of the slices showing the 
tumor to decrease the partial volume effect (e.g. 8 mm lesion for a 4 mm slice). 
 
5. An automated tool (OncoTreat) will be employed to evaluate how the values obtained with this tool 
compare with the manually derived values. The manually derived values will be the measurements used 
for the study.  
 
 
10.4   Determination of tumor progression/response. 
 
Progressive disease 
 
Any patient with clinical or radiographic evidence of progressive disease following any treatment 
cycle will no longer receive pegylated interferon alfa-2b (see Section 5.1).  Radiographic progression 
is defined as appearance of new tumors or an increase in any previously measurable lesion by ≥25% 
in the product of the two longest perpendicular diameters or by 40% in the product of the three 
diameters. The preferred method for tumor measurement is to use the 3 diameters when available.   
If possible, tumor progression should be documented by the appropriate radiological study. For patients 
who develop worsening neurological symptoms, attempts should be made to distinguish progressive 
disease from other causes prior to removing the patient from the study 
Determination of tumor response or progression will be based on the pre-study baseline scan 
performed closest to time of study entry. Progressive disease will be defined based on the comparison 
of the baseline scan to the scan demonstrating best response. 
 
 
1. The amount of tumor enhancement is quite variable in LGGs from one scan to the next. 
Therefore, tumor response/progression will not solely be determined by change in the amount of 
enhancing disease on post contrast T1 images. Measurable change in size/extent must be present on 
FLAIR/T2 images, or on pre-contrast T1 images. 
 

Protocol Vers   12-14-2018                           43 
 
2. Development of new disease or progression in any established lesions is considered progressive 
disease, regardless of response in other lesions – e.g. when multiple lesions show opposite responses, 
the progressive disease takes precedence. 
 
Note: 
• 
CT scans should not be used to determine response. For MRI imaging, the longest diameter can be 
measured from the axial plane or the plane in which the tumor is best seen or measured, provided 
the same plane and MR sequence is used in follow ups. 
 
• 
The cystic components of a tumor are considered in separate tumor measurements.  See options 
below. 
 
Options: 
• 
If the cyst/necrosis is eccentric, the W, T and L of the solid portion should be measured, the 
cyst/necrosis excluded from measurement. 
• 
If the cyst/necrosis is central but represents a small portion of the tumor (<25%), disregard and 
measure the whole lesion. 
• 
If the cyst/necrosis is central but represents a large portion of the tumor, identify a solid aspect of 
the mass that can be reproducibly measured. 
• 
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, change in 
extent/thickness assessed on follow up studies. 
• 
For patients with large cystic components (>25%): One cystic component should be identified in the 
baseline scan. It should be measured separately from the solid component.  It should be measured 
in 3 dimensions in the best sequence likely the T2 sequences.  (L x T x W).  
 
 
10.5   Overall Response Assessment 
The overall response assessment takes into account response in both target and non-target lesion, and 
the appearance of new lesions, where applicable, according to the criteria described in the table below. 
The overall response assessment is shown in the last column, and depends on the assessments of target, 
non-target, and new lesions in the preceding columns.

response; SD; stable disease. 
The section that follows will discuss the selection and evaluation of each of these types of lesions.  
 
 
10.6 Selection of Target and Non-Target Lesions 
 
1. For most CNS tumors, only one lesion/mass is present and therefore is considered a“target” for 
measurement/follow up to assess for tumor progression/response. 
 
2. If multiple measurable lesions are present, up to 5 should be selected as “target” lesions. Target 
lesions should be selected on the basis of size and suitability for accurate repeated measurements. All 
other lesions will be followed as non-target lesions (including CSF positive for tumor cells). 
 
3. The lower size limit of the target lesion(s) should be at least twice the thickness of the slices showing 
the tumor to decrease the partial volume effect (e.g. 8 mm lesion for a 4 mm slice). 
 
4. Any change in size of non-target lesions should be noted, though does not need to be measured. 
 
10.7 Response Criteria for Target Lesions: 
 
Response criteria are assessed in 3 dimensions – the product of L x W x T. An elliptical model volume 
(=0.5L x W x T) is used. 
To assess response/progression, the ratio is calculated:  
 
L x W x T (current scan) / L x W x T (reference scan) 
 
Development of new disease or progression in any established lesions is considered progressive disease, 
regardless of response in other lesions – e.g. when multiple lesions show opposite responses, the 
progressive disease takes precedence. Response Criteria for 3-dimensional target lesions: 
 
Complete Response (CR): Disappearance of all target lesions. 
 
Partial response (PR): ≥ 65% decrease in the sum of the products of the three perpendicular diameters 
of all target lesions (up to 5), taking as reference the initial baseline measurements. 
 
Stable Disease (SD): Neither sufficient decrease in the sum of the products of the three perpendicular 
diameters of all target lesions to qualify for PR (taking as reference the initial baseline measurements), 
nor sufficient increase in a single target lesion to qualify for PD, (taking as reference the smallest disease 
measurement since the treatment started). 
 

Protocol Vers   12-14-2018                           45 
 
Progressive Disease (PD): 40% or more increase in the product of perpendicular diameters of ANY target 
lesion, taking as reference the smallest product observed since the start of treatment, or the 
appearance of one or more new lesions. 
In the rare circumstance that the length of a lesion cannot be determined, then comparison of 2 
dimensional measurements, T x W (product of the longest diameter and its longest perpendicular 
diameter) can be used. 
 
Response Criteria for 2-dimensional target lesions: 
 
Complete Response (CR): Disappearance of all target lesions. 
 
Partial response (PR): ≥50% decrease in the sum of the products of the two 
perpendicular diameters of all target lesions (up to 5), taking as reference the initial baseline 
measurements. 
 
Stable Disease (SD): Neither sufficient decrease in the sum of the products of the two perpendicular 
diameters of all target lesions to qualify for PR (taking as reference the initial baseline measurements), 
nor sufficient increase in a single target lesion to qualify for PD, (taking as reference the smallest disease 
measurement since the treatment started). 
 
Progressive Disease (PD): 25% or more increase in the product of perpendicular 
diameters of ANY target lesion, taking as reference the smallest product observed since the start of 
treatment, or the appearance of one or more new lesions. 
 
Local progression is defined as progression of known residual tumor or the appearance of tumor at 
known prior sites of disease that were at some point without evidence of disease. Distant progression is 
defined as the appearance of tumor at sites other than known prior sites of disease. Distant progression 
most often occurs in the subarachnoid space and may occur at any point within the neuraxis. Although 
rare, extra- CNS metastasis represents distant failure. Combined local and distant progression is defined 
when evaluation of the entire neuraxis reveals local and distant progression. 
 
10.8 Response Criteria for Non-target Lesions 
 
Complete Response (CR): Disappearance of all non-target lesions. 
 
Incomplete Response/Stable Disease (IR/SD): The persistence of one or more non-target lesions. 
 
Progressive Disease (PD): The appearance of one or more new lesions and/or unequivocal progression 
of existing non-target lesions. 
 
Also as part of the response evaluation, for patients who have an omaya reservoir for the cystic part and 
who clinically required omaya taps, we will record the frequency of the taps and the amount of the fluid 
removed from the omaya reservoir. 
10.9 Retrospective Response Review 
MRI imaging for all patients on study will undergo retrospective central review following the completion 
of treatment.

11.0 ADVERSE EVENT REPORTING REQUIREMENTS 
11.1 Purpose 
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. 
 
11.2 Reporting Adverse Events 
This study will be conducted in compliance with the Aflac Cancer & Blood Disorders Service Data Safety 
Monitoring Plan for Phase 1 and 2 studies. In brief, the role of the Data and Safety Monitoring Board is 
to protect the interests of patients and the scientific integrity for all Phase 1 and 2 studies. The DSMB 
consists of 6 members including a chair, a pharmacist, and at least one external member. The DSMB 
meets on a regular basis to review current study results, as well as data available to the DSMB from 
other related studies. The DSMB will provide recommendations for each study reviewed to change the 
study or to continue the study unchanged. Data and Safety Board reports for institutional review boards 
will be prepared. The Principal Investigator assumes responsibility for assuring that the study is carried 
out in accordance with the DSMB. 
 
 
Adverse Event Reporting 
 
Serious adverse event (SAE) or reaction is any untoward medical occurrence (including an abnormal 
laboratory finding) that at any dose: results in death, is life-threatening, requires inpatient 
hospitalization or prolongation of existing hospitalization, results in persistent or significant 
disability/incapacity, is a congenital anomaly/birth defect, or requires medical or surgical intervention in 
order to prevent one of the previous listed outcomes. Medical and scientific judgment should be 
exercised in deciding whether expedited reporting is appropriate in other situations, such as important 
medical events that may not be immediately life-threatening or result in death or hospitalization but 
may jeopardize the patient or may require intervention to prevent one of the other outcomes listed in 
the definition above. These should also usually be considered serious. Examples of such events are 
intensive treatment in an emergency room or at home for allergic bronchospasm; or development of 
drug dependency or drug abuse. 
 
Unexpected adverse drug experience means any adverse drug experience, the specificity or severity of 
which is not consistent with the current investigator brochure; or, if an investigator brochure is not 
required or available, the specificity or severity of which is not consistent with the risk information 
described in the general investigational plan or elsewhere in the current application, as amended. 
“Unexpected” as used in this definition, refers to an adverse drug experience that has not been 
previously observed (e.g., included in the investigator brochure) rather than from the perspective of 
such experience not being anticipated from the pharmacological properties of the pharmaceutical 
product. 
 
Attribution: The investigator will be asked to document his/her opinion of the relationship of the event 
to study medication as follows: 
 
The categories are: 
Definite: The adverse event is clearly related to the study drug. 
Probable: The adverse event is most likely related to the study drug. 

Protocol Vers   12-14-2018                           47 
 
Possible: The adverse event may be related to the study drug. 
Unlikely: The adverse event is doubtfully related to the study drugs. 
Unrelated: The adverse event is clearly not related to the study drug. 
 
For an SAE,  the clinical trials coordinator in the Clinical research office should be notified via phone or 
email within 24 hours of the study personnel becoming aware of the event, and she will notify the 
DSMB. A copy of the completed Serious Adverse Event form must also be sent to Shelley Mays within 3 
working days after the incident.  
 
Copies of all serious adverse event reports will be kept on file in the Clinical Research Office of the 
Cancer Center. 
 
12.0 RECORDS AND REPORTING 
Refer to separate packet for reporting and submission guidelines. 
 
12.1   Protocol amendments, or changes in study conduct 
 
Any change or addition (excluding administrative) to this protocol requires a written protocol 
amendment that must be reviewed by IRB.   
Amendments significantly affecting the safety of subjects, the scope of the investigation or the scientific 
quality of the study require additional approval by the IRB. 
 
Examples of amendments requiring such approval are: 
1. Increases in drug dose or duration of exposure of subjects 
2. Significant changes in the study design (e.g. addition or deletion of a control group) 
3. Increases in the number of invasive procedures. 
4. Addition or deletions of a test procedure required for monitoring of safety. 
 
These requirements for approval should in no way prevent any immediate action from being taken by 
the investigator in the interests of preserving the safety of all patients included in the trial.  
If an immediate change to the protocol is felt to be necessary by the investigator, the IRB must be  
informed immediately.  
Amendments affecting only administrative aspects of the study do not require formal protocol 
amendments or IRB approval but the IRB must be kept informed of such administrative changes.  
 
Examples of administrative changes not requiring formal protocol amendments and IRB approval 
include: 
1. Changes in the staff used to monitor trials. 
2. Minor changes in the packaging or labeling of study drug. 
12.2 Protocol Deviation (NIH Definition): A protocol deviation is any change, divergence, or departure 
from the study design or procedures of a research protocol that is under the investigator’s control and 
that has not been approved by the IRB.  
12.3 Protocol Violation (NIH Definition): Any change, divergence, or departure from the study 
procedures in an IRB-approved research protocol that has a major impact on the subject’s rights, safety, 
or well-being and/or the completeness, accuracy or reliability of the study data.
