Amendment 5 (23-May-2017)
Amendment rationale
As of 04-May-2017, enrollment is ongoing with 35 patients randomized, and 4 patients currently 
receiving study treatment. The purpose of this protocol amendment is to:
-
To add duration of response among the secondary study objectives to better characterize 
the clinical benefit in patients responding to treatment. This information may contribute to 
define the benefit/risk profile in this patient population. 
-
To provide clarification in the description of the secondary objective on the assessment of 
genotype/phenotype relationships of VEGF or other members of the VEGF signaling 
pathway.
-
To add the option of closing recruitment of further patients in a given study cohort if no 
objective responses are observed in patients treated in two out of the three cohorts of 
primary interest during stage 1 of the study. 
-
To update the allowed timeframe for prior use of monoclonal antibodies under eligibility 
criteria. 
-
To update the contraception/pregnancy language to align with the most recent Investigator 
Brochure version 15 (IBv.15) referring to specific requirements in male and female patients 
while receiving study treatment as well as during follow up period. 
-
To remove the exclusion criterion on concomitant treatment with anti-inflammatory and 
anti-platelet agents. Based on clinical data in adult patients a drug-to-drug interaction when 
pazopanib is co-administered with anti-inflammatory agents is not expected.
-
To modify the criteria for starting subsequent treatment cycles. This modification will 
clarify the criteria for starting subsequent cycles when no radiological tumor assessments 
are performed and align the conditions to resume/interrupt study treatment with toxicity 
management guidelines.
-
The sentence on “medications that increase gastric pH” is now updated to Proton Pump 
Inhibitors (PPI). This change is reflected in the protocol section on “Prohibited 
medications.”
-
To add anti-inflammatory and anti-platelet agents in the protocol section “Permitted 
medication to be used with caution”. The use of these agents as a concomitant treatment 
should be monitored since pazopanib may result in an increase of blood pressure and 
bleeding episodes.
-
To clarify that re-initiation of study treatment following hepatotoxicity requires approval 
from the Study Chair.
-
To clarify that PK sampling is not required beyond Cycle 11 since it is unlikely that data 
beyond cycle 11 will provide any modification in the clinical pharmacology assessment of 
the study drug.
-
To define the Per Protocol population and specify which analysis will be conducted in the 
different protocol defined datasets (Per Protocol Population and mITT population).

ABSTRACT
Anti-angiogenic therapy via vascular endothelial growth factor (VEGF) blockade has been shown in several 
studies to be an effective cancer therapy. VEGF is a potent mediator of endothelial proliferation, survival,
and vascular permeability1 and is present in most malignancies; higher VEGF expression has been
correlated with advanced stage or poor prognosis disease.2-8 Platelet derived growth factor (PDGF) 
signaling via PDGFR also plays a key role in angiogenesis by recruiting vascular mural cells, which 
stabilize vessels when VEGF levels decline.9 There are a number of preclinical studies identifying VEGFR,
PDGFR10-20and stem cell factor receptor (KIT) in a wide range of pediatric tumors.17,21
Pazopanib (GW786034) is a small-molecule tyrosine kinase inhibitor that has been shown to prevent ligand
induced receptor autophosphorylation of VEGFR-1,-2,-3, PDGFR-α, -β and c-Kit. In addition, a number
of in vivo murine xenograft studies demonstrate growth inhibition of tumors by pazopanib. This study will
examine the efficacy of pazopanib in children with a variety of relapsed solid tumors. The study will
also seek to further define the toxicities of pazopanib in children, as well as examine biologic markers that 
may help to further define the response characteristics of pazopanib.

EXPERIMENTAL DESIGN SCHEMA
Treatment Schedule
Time
Agent
Days 1 – 28
Oral Pazopanib once daily
This is an open label phase II trial designed to primarily assess the efficacy of pazopanib in children, 
adolescents and young adults with recurrent or refractory solid tumors. Patients will receive pazopanib 
monotherapy and the term “protocol therapy” will be used throughout this document to designate pazopanib 
monotherapy.
Pazopanib will be dosed daily as an oral tablet (450 mg/m2/dose, maximum 800 mg) or as an oral powder 
for suspension (225 mg/m2/dose, maximum 400 mg). Each cycle will be defined as 28 days, with no rest 
periods between cycles.
The first patients enrolled who receive powder suspension will be expected to complete extended 
pharmacokinetic (PK) sampling (Section 7.3.2) in order to obtain PK and safety data in 6 evaluable patients. 
If the 225 mg/m2/dose is not tolerated (≥2 patients with dose limiting toxicities (DLTs) in the first 6
evaluable patients), subsequent new patients will be enrolled at the160 mg/m2/dose level until 6 evaluable 
patients are available for the safety review and the PK analysis.
Patients with benefit (stable disease or an objective response) may continue therapy unless there is evidence
of progressive disease, unacceptable treatment-related toxicity, until death or until study closure [defined 
as 1 year after Last Patient First Visit (LPFV)], whichever occurs first.

BACKGROUND
2.1
Rationale for Development
Vascular endothelial growth factor (VEGF) is a potent mediator of endothelial proliferation,
survival, and vascular permeability exerting its effects principally by induction of VEGFR-2 
auto-phosphorylation.1 VEGF is present in most malignancies; higher VEGF expression has been 
correlated with advanced stage or poor prognosis disease.2-8 Platelet derived growth factor (PDGF)
signaling via PDGFR also plays a key role in angiogenesis by recruiting vascular mural cells, which
stabilize vessels when VEGF levels decline.9 A number of preclinical studies have identified 
VEGFR and PDGFR as potential therapeutic targets in a wide range of pediatric solid tumors; these 
include osteosarcoma, synovial sarcoma, Ewing sarcoma, rhabdomyosarcoma, hepatoblastoma,
Wilms’ tumor, and neuroblastoma.10-22 The presence of the stem cell factor receptor (KIT) has also
been demonstrated by immunohistochemistry in osteosarcoma, synovial sarcoma, Ewing sarcoma, 
rhabdomyosarcoma, Wilms’ tumor, and neuroblastoma.17,23
Pazopanib (GW786034B) is a novel 2H-indazoylpyrimidine orally bioavailable, ATP competitive 
small-molecule tyrosine kinase inhibitor24 that has been shown to prevent ligand induced receptor 
autophosphorylation of VEGFR-1, -2, -3, PDGFR-α, -β and c-Kit with an IC50 < 0.085 μmol/L in 
in vitro studies. It also has modest activity against FGFR1, –R3 and c-fms but is otherwise highly 
selective. Pazopanib is highly protein bound (> 99.9%) thus in in vivo studies, steady state 
concentrations exceeding 18 μg/mL were required to prevent VEGFR2 signaling.24Pharmacokinetic 
studies in adults have shown that these concentrations are readily achievable.
2.2
Preclinical Studies
2.2.1
Antitumor Activity
Pazopanib treatment has been shown to inhibit the growth of a variety of
established (100-250 µL) human tumor xenografts in mouse models including renal
cell carcinoma (Caki-2), colon carcinoma (HT29), non-small-cell lung carcinoma
(NCI-H322), melanoma (A375), prostate carcinoma (PC3), and breast carcinoma
(BT474). Pazopanib demonstrated a wide therapeutic index as it had no effect on
mouse body weight and all animals appeared active and healthy throughout
preclinical studies. Histological analysis following pazopanib administration
demonstrated apoptosis or necrosis of tumor cells; TUNEL assays confirmed
increased apoptosis. This effect correlated with reduced angiogenesis as measured
by decreased concurrent endothelial (CD31) staining. The anti- angiogenic activity 
of pazopanib has also been demonstrated in mouse corneal micropocket and 
Matrigel plug analyses.24
There has been limited pediatric pre-clinical testing of pazopanib; however, growth
delay was observed in one subcutaneous model of neuroblastoma and was
significantly enhanced by concomitant administration of metronomic topotecan.25
The pediatric preclinical testing program (PPTP) also tested the activity of
pazopanib against a limited panel of pediatric sarcoma xenografts and observed
delayed time to progression, but no tumor regression.26 Other multi- targeted
tyrosine kinase inhibitors have been screened by the PPTP using a more complete
solid tumor xenograft panel. The pan-VEGFR inhibitor cediranib demonstrated
broad in vivo antitumor activity (78%; primarily tumor growth delay) including:
3/3
rhabdoid,
2/3
Wilms',
3/3
Ewing,
5/5
rhabdomyosarcoma, 1/3
medulloblastoma, 2/4 glioblastoma, 5/6 neuroblastoma, 4/5 osteosarcoma, with one 
complete response each in a rhabdoid and osteosarcoma xenograft. Similarly the
multi-tyrosine kinase inhibitor sunitinib (VEGFR-1,-2,-3, PDGFR- α, -β, c-Kit,

and FLT3 receptors) showed intermediate (13/34) and high (1/34) levels of
activity against 14 of 34 evaluable solid tumor xenografts, including 4 of 6 
rhabdomyosarcoma, 4 of 5 Ewing tumor, and 2 of 3 rhabdoid tumor. The 
overlapping spectrum of receptors targeted by these agents suggests the broad 
potential of pazopanib for pediatric anti-tumor activity.
2.2.2
Animal Toxicology
In monkeys, no specific toxic effects were seen after 1 month with oral doses of 
up to 500 mg/kg/day, a dose resulting in a Cmax and AUC0-t of 36 μg /mL and 
316 μg•h/mL respectively. However, a dose of 500 mg/kg/day could not be
tolerated for more than 34 weeks due to severe toxicity, consisting of diarrhea, 
anorexia, moribundity and accumulation of crystalline material in a number of 
organs. Monkeys were given 5 or 50 mg/kg/day pazopanib for 1 year, without 
observed toxicity. The no observed adverse effect level (NOAEL) after 1 year 
was 50 mg/kg/day. Mean plasma Cmax and AUC0-t values at 50 mg/kg/day were 
31.8 μg/mL and 235 μg•h/mL, respectively, in male monkeys and 44.0 μg/mL
and 289 μg•h/mL, respectively, in female monkeys after 1 year (Pazopanib 
GW786034 Investigator's Brochure).
There are no published data describing the toxicity of pazopanib in juvenile 
primates. However, doses ≥ 30 mg/kg/day were not tolerated in juvenile rats with 
marked reductions in body weight as well as mortality seen. These effects occurred
at exposures that were similar to or below those expected in pediatric cancer
patients. The specific nature of the effects in these animals is not currently known
but is presumed to be related to vasculogenesis in critical organs such as the heart, 
liver, or kidney. In the two surviving groups, 0.3 and 3 mg/kg/day there did not 
appear to be an effect on body weight although one animal at 3 mg/kg/day had
bilateral broken incisors. Hypertrophy of epiphyseal growth plates, and tooth
abnormalities (including excessively long, brittle, broken and missing teeth, and
dentine and enamel degeneration and thinning) were also observed during
repeated dose administration in mature rat and murine models but notably not in
adult monkeys (Pazopanib GW786034 Investigator's Brochure).
These findings are consistent with previous observations of physeal dysplasia and 
ovarian and uterine changes in juvenile animals, including cynomolgus monkeys, 
during the preclinical testing of other potent VEGF blocking agents raising concern 
of
potential pediatric-specific adverse effects on
long-term
growth and 
development.27,28 Nonetheless, at least in murine models, the changes in bone 
growth appeared reversible after cessation of therapy.27 Consistent with the known
roles of VEGF in follicle maturation and corpus luteum formation there were
significant reductions in female rat fertility at pazopanib doses > 30 mg/kg/day.
In males, reductions in testicular and epididymal weights were observed at ≥30 
mg/kg/day and sperm production, motility and concentration were reduced at
100 mg/kg/day, but this did not result in a functional effect on mating or male
fertility. Consistent with the critical role of VEGF in embryogenesis, cardiac 
malformations were observed in rat fetuses at maternal doses of 3 and 10 mg/kg/day.
Delayed ossification (≥3 mg/kg/day), embryo lethality and reduced fetal body
weight were observed at 10 mg/kg/day. The NOAEL for developmental toxicity 
in the rat was 1 mg/kg/day (Pazopanib GW786034 Investigator's Brochure).
2.2.3
Preclinical Pharmacology
14C-pazopanib demonstrates wide tissue distribution. The majority of pazopanib 
measured in plasma is unmodified, minor metabolites including mono-oxygenated

and de-methylated forms. In rats and monkeys, pazopanib is predominately 
excreted in the feces with a small amount eliminated in the urine. Following
absorption in the monkey, pazopanib is principally metabolized in the liver by
oxidation and di-demethylation with glucuronidation. In vitro studies indicate that
the oxidative metabolism of pazopanib in human liver microsomes is primarily
mediated by CYP3A4, with minor contributions from CYP1A2 and CYP2C8.
There appears to be minimal potential for inductive effects on CYP enzyme
activities in rats or monkeys after oral doses (300 and 500 mg/kg, respectively) of
pazopanib for 1 month. (Pazopanib GW786034 Investigator's Brochure)
In order to optimize in vivo dosing for pazopanib and determine whether Csteady
state or Cmax best correlated with activity, once and twice daily p.o. dosing was
compared with a continuous infusion of a pazopanib analogue (GW771806). Both
HT29 tumor growth inhibition and anti-angiogenic activity in the Matrigel plug
assay correlated with steady state concentrations of pazopanib and not with Cmax
or exposure (AUC). Complete tumor growth inhibition was achieved with a steady-
state plasma concentration of 2.67 μMol/L pazopanib. This value corresponded
with a pazopanib steady-state concentration of 18 μg/mL. At this level, pazopanib
also demonstrated inhibition of VEGF-induced VEGFR2 phosphorylation in vivo,
but if the concentration dropped below this level, inhibition was minimal, again 
indicating the need to sustain effective levels.24
2.3
Adult Studies
As of 09 September 2012, approximately 5000 patients have received pazopanib as monotherapy 
or in combination out of approximately 7000 patients enrolled in pazopanib oncology clinical 
studies. Data collected to date show that pazopanib administration at 800 mg daily is associated 
with a reasonable safety profile and encouraging efficacy in various oncology settings. Pazopanib 
is approved for the treatment of adult patients with advanced renal cell carcinoma (RCC) and for
the treatment of adult patients with soft tissue sarcoma who have received prior chemotherapy. 
Results of pharmacokinetic and pharmacodynamic analyses demonstrate that (a) pazopanib is 
absorbed after oral administration; (b) a plateau is reached in steady-state systemic exposure at a 
dose of 800 mg daily; (c) a maximum tolerated dose has not been reached at pazopanib doses up 
to 2000 mg daily; and (d) doses of pazopanib that maintain plasma pazopanib concentrations 
above 15 μg/mL (i.e., 800 mg daily and 300 mg twice daily [BID]) are associated with 
pharmacodynamic and clinical effects. Pazopanib administered as oral doses up to 800 mg daily 
is being developed by Novartis for the treatment of a variety of cancers.
2.3.1
Pharmacokinetic and Pharmacodynamic Data in Adults with Cancer
The oral bioavailability of pazopanib reflects absorption that is limited by solubility
above doses of 800 mg once daily; therefore, increases in doses above 800 mg, up
to the highest dose evaluated (2000 mg), in the fasted state will not result in
increased systemic exposure. Geometric mean pazopanib t½ values ranged from
18.1 to 52.3 hours. The geometric mean t½ was 30.9 hours in the 800 mg once
daily dose group, the monotherapy dose selected for administration in Phase II and
Phase III clinical trials. The tmax was 3 to 4 hours. The oral bioavailability of
pazopanib may also be affected by its substrate affinity for gut efflux transporters.
Oral absorption is significantly enhanced when pazopanib is dosed with food; 
therefore, it is recommended to administer pazopanib on an empty stomach, at least 
1 hour before or 2 hours after a meal.
The absolute bioavailability of pazopanib (median 21%) suggests that the majority 

Novartis
Confidential
Page 23

Protocol No. VEG116731
(67%) of the oral dose recovered unchanged in feces represents unabsorbed drug.
Pazopanib is not extensively metabolized and first-pass metabolism is minor,
consistent with its low plasma clearance and small volume of distribution.
Age, race, and gender had no effect on pazopanib PK. Mild/moderate renal 
impairment is not expected to influence pazopanib exposure, and dose adjustment 
is not necessary. Based on baseline hepatic function, 400 mg pazopanib is
recommended for patients with mild impairment (defined as either normal bilirubin
and any degree of alanine aminotransferase [ALT] elevation or as an elevation of
bilirubin up to 1.5x upper limit of normal [ULN] regardless of the ALT value),
and 200 mg for patients with moderate impairment (defined as an elevation of
bilirubin >1.5 to 3xULN regardless of the ALT values). The maximum dose of
pazopanib (200 mg) administered to patients with severe hepatic impairment did 
not achieve therapeutic plasma concentrations. Therefore, pazopanib is not 
recommended in patients with severe hepatic impairment (defined as total bilirubin 
>3xULN regardless of any level of ALT).
In clinical studies with pazopanib, events of QT prolongation or torsade de pointes 
have occurred. Pazopanib should be used with caution in patients with a history of
QT interval prolongation, patients taking antiarrythmics or other medications that
may potentially prolong QT interval, or those with relevant pre- existing cardiac 
disease. When using pazopanib, baseline and periodic monitoring of ECGs and
maintenance of electrolytes (calcium, magnesium, potassium) within normal range 
is recommended.
Pharmacodynamic data indicate that pazopanib, at a monotherapy dose of 800 
mg once daily, results in effects consistent with inhibition of the VEGF receptors 
it was designed to target (i.e., increases in VEGF and decreases in soluble 
VEGFR2). Concentration-effect relationships were observed between trough 
plasma pazopanib concentrations and an increase in blood pressure in the First 
Time in Human study, as well as in the percent change from baseline in soluble 
VEGFR2 nadir in the Phase II study in renal cell carcinoma. The trough plasma 
pazopanib concentrations associated with one-half the maximal effect (EC50) in 
both concentration effect relationships were similar (12 to 15.3 μg/mL for 
hypertension and 21.3 μg/mL for soluble VEGFR2), which demonstrates that there
is a consistent inhibition of VEGF receptor(s) in patients with cancer when plasma 
pazopanib concentrations are maintained above 15-20 μg/mL.
2.3.2
Safety Data in Adults with Cancer (adverse events and serious adverse events)
In a randomized, double-blind, placebo-controlled Phase III study of pazopanib 
monotherapy in patients with advanced RCC, the median time on treatment was 
approximately twice that on placebo (7.4 months versus 3.8 months).29 The overall
frequency of adverse events (AEs) reported during the study was higher in the
pazopanib arm (92%) compared with placebo (74%). Most common AEs reported
in >20% patients in the pazopanib arm (as of 23 May 2008) were diarrhea
(52%), hypertension (40%), hair color change (depigmentation; 38%), nausea 
(26%), anorexia (22%), and vomiting (21%). These AEs were all reported at a 
higher incidence in the pazopanib arm than in the placebo arm. Most of these events
were Grade 1 or 2 using the National Cancer Institute Common Toxicity Criteria 
for Adverse Events (NCI CTCAE) Version 3.0. More Grade 3 AEs were reported
in the pazopanib arm (33%) compared with the placebo arm (14%). The frequency

Protocol No. VEG116731
of Grade 4 AE and Grade 5 events was similar between the pazopanib and placebo
arms: Grade 4 in 7% and 6%, respectively; Grade 5 in 4% and 3%, respectively.29
At the time of the final overall survival (OS) analysis, a subsequent review of
safety data did not reveal any changes to the previously observed safety profile; no 
new safety signals were detected.
Based on the analysis of the safety data integrated across 3 RCC studies, including 
a Phase II study of pazopanib monotherapy in patients with advanced RCC and a
single arm Phase III extension study of pazopanib monotherapy in patients with
advanced RCC as of January 9, 2009 (N=593), the most common AEs and serious 
adverse events (SAEs) were similar to those observed in the pazopanib arm of the 
monotherapy Phase III study.
In a randomized placebo-controlled Phase III study of pazopanib monotherapy in 
patients with soft tissue sarcoma [STS]), the median time on pazopanib was 19.4 
weeks, as compared with 8.1 weeks in the placebo arm. The most common AEs 
(≥20%) reported in the pazopanib arm (as of May 23, 2011) were fatigue (65%), 
diarrhea (59%), nausea (56%), weight decreased (51%), hypertension (42%), 
decreased appetite (40%), hair color changes (39%), vomiting (33%), tumor pain 
(30%), dysguesia (28%), headache (23%), musculoskeletal pain (23%), myalgia 
(23%), gastrointestinal pain (23%), and dyspnea (20%). Twenty-eight percent of 
patients on placebo and 63% of patients on pazopanib experienced an AE of 
maximum Grade 3 or higher. The proportion of patients who experienced 
maximum Grade 4 and Grade 5 AEs was similar in both treatment arms. 30
An analysis of integrated safety data from a Phase III study in patients with STS 
and a single arm Phase II study of pazopanib monotherapy in patients with STS 
showed a safety profile similar to that observed in the pazopanib arm of the 
Phase III study alone. Increased rates of myocardial dysfunction, venous thrombo-
embolic events, and pneumothorax were newly observed in the STS studies as
compared to RCC. Rare but severe AEs previously described for VEGFR inhibitors, 
such as cardiac/cerebral ischemia, hemorrhage, and bowel perforation, were 
observed with pazopanib treatment.
A review of SAEs across oncology studies revealed that the most frequently 
reported SAEs (≥70 events), regardless of causality and treatment regimen, as of 
September 9, 2011 in decreasing order of frequency were increased ALT, dyspnea, 
vomiting, abdominal pain, pyrexia, diarrhea, anemia, pneumonia, dehydration, and 
aspartate aminotransferase (AST) increased.
2.3.3
Efficacy Data in Adults with Cancer
Pazopanib 800 mg once daily has shown efficacy and/or encouraging efficacy 
signals in the following settings:

RCC: The primary analysis of the primary endpoint, progression-free survival 
(PFS), revealed a large and highly statistically significant improvement in PFS
in the pazopanib-treated patients compared to placebo- treated patients (hazard 
ratio [HR] 0.46, 95% confidence interval [CI] 0.34 to 0.62, p<0.0000001). The 
median PFS in the pazopanib arm was more than double that in the placebo
arm: 9.2 months (95% CI, 7.4, 12.9) versus 4.2 months (95% CI, 2.8, 4.2),
respectively. The response rate (RR), defined as the percentage of patients who 
achieved either a confirmed complete response (CR) or partial response (PR)

Amended Protocol Version 05 Clean
Protocol No. VEG116731
according to Response Evaluation Criteria in Solid Tumors (RECIST) was 
significantly higher for the pazopanib arm compared with the placebo arm by 
Independent Review Committee (IRC) assessment (30% vs. 3%, p<0.001). In
the pazopanib arm, the median duration of response was 58.7 weeks (95%
CI, 52.1 to 68.1 weeks) and the median time to response was 11.9 weeks (95% 
CI, 9.4 to 12.3 weeks) by IRC assessment.29 The median OS at final analysis
was 22.9 months in the pazopanib arm and 20.5 months in the placebo arm. The
final OS was not statistically different between the pazopanib arm and the
placebo arm in (HR = 0.91, stratified log-rank p-value, 0.224). Of note, 54% of 
patients in the placebo arm received pazopanib, many starting early in the study, 
and an additional 12% received other systemic therapies.

Soft Tissue Sarcoma: In a Phase III study a statistically significant 
improvement in PFS but not OS was observed in the pazopanib arm compared
with the placebo arm. Median progression-free survival was 4.6 months for
pazopanib compared with 1.6 months for placebo (hazard ratio [HR] 0.31, 95%
CI 0.24-0.40; p<0.0001). Overall survival was 12.5 months with pazopanib 
versus 10.7 months with placebo (HR 0.86, 0.67-1.11; p=0.25).30 In a Phase II 
Study, the PFS rate at 12 weeks, based on investigator assessment, was 18 of
41 patients (43.9%) for leiomyosarcoma;18 of 37 patients (48.6%) for synovial 
sarcoma; 5 of 19 (26.3%) for adipocytic sarcoma; and 16 of 41 patients (39.0%)
for other types of sarcoma.31

Ovarian cancer: 11 of 36 patients (31%) experienced a cancer antigen-125 
(CA-125) response to pazopanib, with a median time to CA-125 response of
29 days and median duration of response of 113 days. Excluding one patient 
whose CA-125 decreased before she received the first dose, the biochemical
response was 28% (10 patients). Overall response rate based on modified
Gynecologic Cancer Intergroup (GCIG) criteria (incorporating CA-125, 
RECIST, and clinical assessment) was 18% in patients with measurable disease 
at baseline, and was 21% in patients without measurable disease at baseline. 
Median PFS was 84 days.32

Early-stage Non-Small Cell Lung Cancer (NSCLC): 30 of 35 patients 
(86%) experienced a reduction in tumor volume after short-term use of 
pazopanib (median duration of 16 days) as assessed by high-resolution 
computed tomography (HRCT) after preoperative pazopanib treatment.33

ErbB2-positive advanced or metastatic breast cancer: A higher response 
rate (36.2% versus 22.2%) by independent review at Week 12 was observed in
patients on combination lapatinib 1000 mg once daily + pazopanib 400 mg once
daily compared with lapatinib 1500 mg once daily as a monotherapy, 
respectively.34

Cervical cancer: There was a 34% reduction in risk for progression for 
patients receiving pazopanib relative to lapatinib (hazard ratio: 0.66; 90% CI: 
0.48, 0.91). The median time to investigator-assessed PFS was 17.1 weeks in 
the lapatinib group and 18.1 weeks in the pazopanib (one-sided p=0.013).35
Pazopanib has not shown signals of efficacy in Phase II studies conducted in 
multiple myeloma (VEG20006) 36 or glioma (VEG102857).
Most important to the rationale for this current trial are the results from the study 
of pazopanib in adult patients with advanced or metastatic soft tissue sarcoma. 
These combined findings form the basis for including several cohorts for soft tissue 
and bone sarcoma as well as the embryonal tumors specific to pediatrics, which are 
of mesenchymal origin.

To date, results of correlative biologic assays specific to pazopanib are limited. 
Most studies sample platelet-poor plasma and serum for cytokine/angiogenic factor 
profiling which include VEGF, sVEGFR1, and sVEGFR2 and whole blood for
circulating endothelial cell subsets (CECs). In two separate Phase II studies of
renal cell and NSCLC presented at the 2008 annual meeting of the American
Society for Clinical Oncology (ASCO) a decrease in sVEGFR2 compared with
baseline was significantly correlated with tumor response (p <0.05).37,38 In adult
patients with metastatic imatinib-refractory gastrointestinal stromal tumors treated 
with sunitinib, another VEGF and c-kit targeting multityrosine kinase inhibitor, 
biomarker analysis of CECs, monocytes, VEGF, and sVEGFR-2 were consistently 
modulated by treatment. In this study, changes in CECs and monocytes rather than 
plasma markers differed between the patients with clinical benefit and those with
progressive disease.39 In pediatric patients with refractory solid tumors treated
with pazopanib, baseline levels of plasma soluble VEGFR-2 and endoglin levels
were significantly decreased when measured after 2 weeks of treatment, while
placental growth factor levels were significantly increased over the same time 
points. There was no significant change in VEGF or plasma soluble VEGFR-1
levels with pazopanib therapy.40
This study will continue to examine the effects of pazopanib therapy on cytokines 
and angiogenic factors.
In part, genetic predisposition may account for the variability in biomarker or 
clinical response to anti-VEGF treatment. Three lines of ongoing investigation 
justify voluntary collection of DNA in this trial to evaluate relationships between 
discovered associations in the adult population and pazopanib effects in the 
pediatric population, and to assess age as a covariate in these relationships.
1)
Recently, Dr.
and
 colleagues identified a single nucleotide 
polymorphism in KDR (the gene that encodes VEGFR2) that is reproducibly 
associated with the baseline levels of circulating soluble VEGFR2 in three 
separate cohorts: healthy volunteers of the Old Order Amish community; 128 
unrelated cancer patients at the 
; and adult RCC patients
enrolled on the phase II trials of pazopanib. Subsequently, they demonstrated
that in the RCC patients treated with pazopanib for 4 weeks, this
polymorphism is associated with a greater magnitude decline in plasma 
sVEGFR2 (Late Breaking Abstract, 2011 Am Soc Clin Pharm & Therapeutics
Meeting). This genotype/phenotype relationship is currently being studied by 
another cooperative group (the CALGB Pharmacology and Experimental 
Therapeutics Committee) in adult patients who are taking agents in this class.
Determination of the effect of this KDR polymorphism and sVEGFR2 degree
of change on disease response to therapy is ongoing.
2)
Several genotypes at the VEGFA locus have been associated with increased 
or decreased VEGF production and prognostic and predictive marking of 
treatment outcomes. In most VEGF signaling pathway inhibitor trials 
analyzed so far, 4 SNPs in the promoter region have been evaluated for 
associations with clinical outcomes: -2578, -1498, -1154, and -634. These 
studies have yielded inconsistent findings. In amyotrophic lateral sclerosis, 
similar inconsistencies led to confusion on the predictive role of VEGF alleles
until a meta-analysis by Lambrechts, et al.41 revealed only -2578 to have a
clinically relevant and consistent effect. Such studies in oncology are ongoing.

We propose to evaluate all common variation across the VEGFA locus with
tagging SNPs representing all common variation in the haplotype analyzed
for association with changes in VEGF-A post pazopanib exposure, response 
rate, and progression-free survival.
3)
GlaxoSmithKline has recently published results
of a candidate gene 
association study in adult RCC patients treated with pazopanib.25 Several 
polymorphisms in candidate genes demonstrated associations with response 
rate and progression-free survival. Validation and elaboration of these 
findings will become available prior to completion of this trial. Based on the 
adult findings, additional
markers may
be explored
in
the
pediatric 
population.
2.4
Pediatric Studies
2.4.1
Pediatric Phase I Studies
The Children’s Oncology Group (COG) conducted a phase I study of pazopanib 
in children with STS or other refractory solid tumors (ADVL0815). This study was
performed to determine the maximum tolerated dose (MTD) of two formulations
of oral pazopanib; to define and describe the toxicities, pharmacodyamics and
pharmacokinetics (PK) of pazopanib administered as a tablet (Part 1) or powder 
suspension (Part 2a); and to explore pazopanib induced changes in tumor blood
volume and vascular permeability (Ki) using dynamic contrast enhanced MRI
(DCE-MRI) in a subset of patients with STS (Part 2b). During part 1, pazopanib 
(tablet formulation) was administered once daily in 28 day cycles at 4 dose levels 
(275 to 600 mg/m2) using the rolling-six design. Dose determination for a powder 
suspension (Part 2a) was initiated at 50% of the MTD for the intact tablet. Ten
patients with STS underwent DCE-MRI scanning at baseline and 15 ± 2 days after 
initiation of pazopanib at the tablet MTD (Part 2b). A total of 53 patients were
enrolled; 51 were eligible [26 male, median age 12.9 yrs (range 3.8-23.9)].
Hematologic and non-hematologic toxicities were generally mild. Diarrhea, nausea,
vomiting, fatigue, proteinuria and hypertension were the most commonly reported
side effects. Only cycle 1 DLTs were considered for determination of the MTD 
and included Grade 3 lipase, amylase and ALT elevation, proteinuria and
hypertension. One patient with occult brain metastasis in the imaging expansion
cohort also had Grade 4 intracranial hemorrhage. The MTD was 450 mg/m2/dose
for tablets, and 160 mg/ m2/dose for powder suspension; two isolated and reversible 
Grade 3 ALT elevations were seen at the powder suspension dose of 225 mg/
m2/dose. Toxicities requiring dose modification and/or discontinuation in later 
cycles included tumor pain (n=2), ALT elevation (n=2), diarrhea, myalgia 
associated with microangiopathic hemolytic anemia, hand foot syndrome, weight 
loss, fistula formation at a site of prior RT, growth plate abnormality and recurrent
neutropenia (each n=1). Three of 27 patients treated at the MTD had asymptomatic
decreases in left ventricular systolic function; all were reversible and the drug was
successfully reintroduced in two. Asymptomatic sinus bradycardia was noted in 4
patients, all ≥12 years. No QTc prolongation was observed.
Steady state trough concentration (Ctrough) was reached by day 15 and exceeded
15µg/ml at all dose levels. There was marked inter-patient variability in PK 
parameters resulting in substantial overlap between dose levels and trough 
concentrations did not appear dose-dependent. Patients received 1-22+ cycles

(median = 2). One patient each with hepatoblastoma or desmoplastic small round 
and all 5 who received therapy for a year or more had Ctrough ≥30 μg/ml. All 
patients with evaluable DCE-MRI (n=8) experienced decreases in tumor blood 
volume and permeability (Ki; p<0.01). PlGF increased, whereas endoglin and 
soluble VEGFR2 decreased (p<0.01; n=31).40

Pharmacology/Pharmacokinetics/Correlative Biological Studies 
Hypertension was seen in several patients in the pediatric Phase I dose escalation 
study, which is a class effect seen with
other VEGF blocking agents. Such
hypertension has been treatable with anti-hypertensives and may ultimately be a 
biomarker of treatment effect. Pediatric specific guidelines for the management 
of VEGF blocking agent-induced hypertension have been developed for other COG
Developmental Therapeutics studies (e.g. ADVL0413, ADVL0612, ADVL0714,
and ADVL0815) and will be used for this trial. In the adult Phase I pazopanib trial,
a relationship between steady-state trough concentrations and the occurrence of
hypertension could be described by a logistic regression model. Twenty (77%) of
the 26 patients with Ctrough values > 15 μg/mL on Day 22 developed
hypertension, versus 11 (39%) of the 28 patients who had lower Ctrough values.42
In the pediatric phase I trial, the mean Ctrough in patients with drug related
hypertension (n=13) was 42±13 g/ml versus 29±13 g/ml in normotensive 
patients (n=27; p=0.008), suggesting a relationship between blood pressure
elevation and drug exposure. In addition pediatric patients with a best response of 
stable disease had a 30% incidence of blood pressure elevation within the first two 
cycles, and 47% incidence over all cycles. This trial will seek to expand our
understanding of the relationship of pazopanib Ctrough to hypertension, and the 
utility of hypertension as a pharmacodynamic or predictive marker.
2.5
Overview of Proposed Pediatric Phase II Trial
This is a two-stage open label phase II trial of pazopanib in children, adolescents and young 
adults
with recurrent or refractory solid tumors. Tumors of primary interest are 
rhabdomyosarcoma, non-rhabdomyosarcomatous soft tissue sarcoma (including synovial sarcoma,
alveolar soft part sarcoma and desmoplastic small round cell tumor) and Ewing sarcoma/peripheral
PNET. Tumors of secondary interest include hepatoblastoma, neuroblastoma (measurable and 
evaluable), and osteosarcoma.
Each tumor type defines a cohort resulting in 7 total cohorts. The first stage of the study involves 
enrolling an initial 10 patients into each cohort. The response rate will be determined for each cohort
after the target enrollment of 10 patients is reached for that cohort. If one or more confirmed
responses are observed in the first 10 evaluable patients in a cohort, an additional 10 patients will 
be enrolled into that cohort in the second stage of study. Thus, for cohort(s) with one or more
confirmed responses in the first stage of study, a total of 20 patients will be enrolled and evaluated 
to determine efficacy.
Eligible patients will receive pazopanib monotherapy. Pazopanib will be dosed daily as an oral 
tablet (450 mg/m2/dose, maximum 800 mg) or as a powder for oral suspension (225 mg/m2/dose, 
maximum 400 mg) in 28 day cycles.
The MTD for pazopanib tablets was 450 mg/m2/dose as determined by ADVL0815/PZP114411, 
the COG Phase I study in children with relapsed or refractory solid tumors. For the powder 
suspension formulation, the selected starting dose is higher than the protocol-defined MTD of 160 
mg/m2/dose established in ADVL0815. This decision is driven by the considerations that the 160

isolated and reversible laboratory-defined DLTs were observed at the 225 mg/m2/dose.
The first patients who are enrolled to receive pazopanib as powder suspension at 225 mg/m2/dose 
daily will be closely monitored for safety and for the occurrence of dose-limiting toxicity during 
the first cycle (28 days) of therapy. Patients who either receive 225 mg/m2/dose daily for at least 24
days (85% of the dose for a 28-day cycle with powder suspension at 225 mg/m2/dose) or are 
withdrawn from dosing due to one or more protocol-defined dose-limiting toxicities (Section 5.1) 
during the first cycle will be considered evaluable for the purpose of this safety review. Six
evaluable patients are required.
The first patients enrolled to receive powder suspension at 225 mg/m2/dose will also be expected 
to complete extended PK sampling (Section 7.3.2) with blood samples collected prior to dosing, 
and 30 min, 1, 2, 4, 6, and 8 hours after the pazopanib dose on Day 1 and Day 15 ± 1 day of 
Cycle 1 (with no pazopanib dose modification or adjustment in the 10 days before Cycle 1 Day
15 sample collection). Patients who can provide adequate blood samples for the 2 scheduled 
extended PK collections will be considered to be evaluable patients for the purpose of this PK
analysis, and PK data are required from 6 evaluable patients. If one or more of the first 6 patients 
fails to provide blood samples as specified in the protocol or if it is known that for some reason a 
patient’s collected blood sample(s) cannot be analyzed, that patient will be determined to be non-
evaluable for this analysis, and one or more additional patients will be enrolled for treatment with 
pazopanib as powder suspension for the purpose of obtaining the extended PK samples.
Because patients receiving the powder suspension enrolled in the safety review group may be 
different from those in the PK analysis group, enrollment onto powder suspension may follow 
several different paths:

If ≥2 out of 6 evaluable patients have dose- limiting toxicities (DLT and as defined in 
Section 5.1) within the first cycle, then enrollment onto 225 mg/m2/dose pazopanib will
be halted. Subsequent new patients will be enrolled at the 160 mg/m2/dose level until 6
evaluable patients from this dose group are available for the safety review and 6 patients 
are available for PK analysis at 160 mg/m2/dose.

If 6 PK evaluable patients are enrolled prior to enrollment of 6 patients who are 
evaluable for the safety review, the extended PK sample collection may be suspended.

If < 2 DLTs are observed during the first cycle in 6 patients evaluable for safety at 225
mg/m2/dose and these 6 patients are not all evaluable for the PK analysis, then 
enrollment will continue until 6 PK evaluable patients are available.
All patients will be closely monitored with clinical and laboratory observations for adverse 
events.
Tumor response will be evaluated using appropriate imaging assessments at baseline, prior to
Cycle 3, Cycle 5, Cycle 8, Cycle 11 and then every 3rd cycle thereafter.
 
In addition, we will assess KDR polymorphism and 
pazopanib-induced change in soluble VEGFR2; VEGF-A genotype and changes in VEGF-A 
concentration; KDR and VEGF-A genotypes and response rate, and progression-free survival; 
and candidate SNPs and clinical endpoints as identified in the adult population.
The primary analysis will be performed 20 weeks after the last patient’s first visit in the three 
cohorts of primary interest (rhabdomyosarcoma, non-rhabdomyosarcomatous soft tissue sarcoma 
and Ewing sarcoma/peripheral PNET).
The study will be completed one year from the date of the last patient’s first visit and the end of 
study analysis will be performed at the time of study completion.

ENROLLMENT PROCEDURES AND ELIGIBILITY CRITERIA
3.1
Study Enrollment
3.1.1
Patient Registration
No study-specific procedure will start before the signature of the informed 
consent form (and assent, according to institutional guidelines), defining the 
study entry.
Prior to enrollment on study, patients must be assigned a COG patient ID 
number. This number is obtained once authorization for the release of
protected health information (PHI) has been obtained. The COG patient ID
number is used to identify the patient in all future interactions with COG. If
you have problems with registration, please refer to the online help.
Upon completion of all required baseline assessments, the investigator or 
authorized site staff will assign each eligible patient a Sponsor study-specific 
patient identification number. Each site will be assigned a range of patient 
numbers, and this information is provided in the Study Procedure Manual
(SPM). The patient ID number consists of 6 digits including leading zeros.
Using
this 
patient
ID 
number
and 
patient’s 
histology
cohort 
(rhabdomyosarcoma, non- rhabdomyosarcomatous soft tissue sarcoma, Ewing 
sarcoma/peripheral
PNET, osteosarcoma,
neuroblastoma
(measureable),
neuroblastoma (evaluable) or hepatoblastoma), each patient will then be
registered into the interactive webresponse system (IWRS). The IWRS will
then provide a randomization number consistent with the patient’s tumor type.
All sessions to IWRS are confirmed with an onscreen confirmation which
will be also sent via e-mail to the site upon completion of each call. Study-
specific instructions will be provided for the use of IWRS in the Study 
Procedures Manual and in the user manual.
3.1.2
Patient Rescreening
Patients may be rescreened if the reasons for the initial screen failure were non-
medical or if the medical issues leading to screen failure have resolved. 
Approval by the Study Chair is required prior to rescreening. A new informed 
consent form must be signed. Please refer to detailed instructions in the
Study Procedure Manual for rescreening.
3.1.3
Institutional Review Board (IRB) Approval
Local IRB/REB approval of this study must be obtained by a site prior to 
enrolling patients.
Sites must submit the following documents to Novartis prior to approval to
enroll subjects and receive study drug:

Study Enrollment Status
The study will remain open for enrollment into any of the 7 cohorts until the 
following:
1.
The cohorts with the tumors of primary interest have completed 
enrollment 
and
2.
All patients with tumors in the primary interest cohorts have either 
discontinued from study treatment or have completed a minimum of 5 
cycles of treatment
While the study remains open for enrollment, enrollment into each cohort will 
proceed independently from the other cohorts (see Section 9.2 for details). The 
enrollment in the cohorts of secondary interest may remain open if after
review of the data, an efficacy signal is seen.
The Sponsor in agreement with 
COG may consider the option of 
closing recruitment of further patients in a given study cohort in the case that no 
objective responses are observed in the first 10 evaluable patients in two out of 
the 3 cohorts of primary interest during stage 1 of the study. 
3.1.5
Study Enrollment
Patients may be enrolled on the study once all eligibility requirements for the 
study have been met. Specific procedures related to the requirements for patient 
enrollment are described in protocol Section 3 and in the Study Procedures 
Manual. Sites will be required to complete a session into the (IWRS) to record 
patient information as described in Section 3.1.1.
3.1.6
Timing
Patients must be enrolled before treatment begins. The date protocol therapy is 
projected to start must be no later than 5 calendar days after the date of
study enrollment. See Section 3.2 for timing requirements for eligibility studies.
See Section 3.1.7 for timing requirements for baseline studies to be obtained
prior to start of therapy. Note: Repeat laboratory and imaging studies may
be required if enrollment and start of therapy do not occur on the same 
day.
3.1.7

LaboratoryStudies: If more than 7 calendar days elapse between
the date laboratory studies to determine eligibility were obtained

Novartis
Confidential
Page 33
Amended Protocol Version 05 Clean
Protocol No. VEG116731
(Section 3.2.8) and the start date of treatment, then the following
studies must be repeated prior to initiating protocol therapy: CBC
with differential, bilirubin, ALT (SGPT) and serum creatinine. If any
of these repeat laboratory assessments are outside the parameters 
required for eligibility (labs may again be repeated within 48-72 
hours), then the patient is not eligible for protocol therapy.
Note: For hepatoblastoma patients, blood for serum alpha fetoprotein 
(AFP) must be drawn within 48 hours prior to initiating protocol 
therapy. It is not required that the results be known prior to 
enrollment.
3.1.7.2
Imaging Studies: Imaging studies must be performed within 14
calendar days prior to initiating protocol therapy. If more than 14 
calendar days have elapsed between the date imaging studies to 
determine eligibility were obtained (Section 3.2) and the enrollment 
date, then repeat imaging assessments must be obtained prior to 
initiating protocol therapy.
3.1.7.3
Cardiac studies: Cardiac ECHO and electrocardiogram (ECG) must
be performed within 14 calendar days prior to initiating protocol
therapy. If more than 14 days have elapsed between the date cardiac
studies to determine eligibility were obtained (Section 3.2.8.4) and the 
enrollment date, then repeat cardiac studies must be obtained prior to 
initiating protocol therapy.
3.1.7.4
Bone Marrow (BM) Evaluations (Solid Tumors with known Marrow
Involvement): Bone Marrow aspirate and/or biopsy must be
performed within 14 calendar days prior to initiating protocol therapy.
If the Bone Marrow evaluation was performed more than 14 days
prior to enrollment date and if it was negative, then BM aspirate 
and/or biopsy must be repeated prior to initiating protocol therapy. If 
the Bone Marrow evaluation was obtained more than 14 calendar days
prior to enrollment and it was positive, and there was no intervening
treatment provided to the patients, then there is no need to repeat the
Bone Marrow evaluation.

TREATMENT PROGRAM
4.1
Overview of Treatment Plan
Pazopanib will be dosed daily as an oral tablet at 450 mg/m2/dose or as a powder for oral suspension 
at 225 mg/m2/dose.
For the tablet formulation, the maximum tolerated dose (MTD) was 450 mg/m2/dose as determined
by ADVL0815/PZP114411, the COG Phase I study. The maximum dose to be administered daily 
for tablets is 800 mg.
For the powder suspension formulation, the selected starting dose is 225 mg/m2/dose, higher than
the protocol-specified MTD of 160 mg/m2/dose established in study ADVL0815. This decision is
driven by the considerations that the 160 mg/m2/dose may result in exposure that is suboptimal to
demonstrate efficacy and that only two isolated and reversible laboratory- defined dose-limiting 
toxicities (DLTs) were observed at the 225 mg/m2/dose. The maximum dose to be administered
daily for oral suspension is 400 mg.
Note: The first patients enrolled who receive powder suspension will be reviewed for safety and
will be expected to complete extended PK sampling (Section 7.3.2). A minimum of 6 evaluable
patients for safety and 6 evaluable patients for PK are required as described in section 2.5.
Safety and PK data from these patients will be reviewed prior to further enrollment of patients
requiring powder suspension to determine if the 225 mg/m2/dose is tolerated and if the PK
exposure is similar to exposure in adults associated with clinical efficacy. If 225 mg/m2/dose is not
tolerated (≥2 patients with DLTs in the first 6 evaluable patients during their first cycle), all
subsequently enrolled patients will receive 160 mg/m2/dose, and an additional 6 subjects will be 
assessed for safety and PK.
Patients will take pazopanib continuously, once daily. A cycle will be defined as 28 days with no
rest periods between cycles. Patients with benefit (stable disease or an objective response) may 
continue therapy unless there is evidence of progressive disease or unacceptable treatment-related
toxicity, death or until study closure defined as 1 year after Last Patient First Visit.
Patients must remain on the same formulation of pazopanib throughout the duration of
their protocol therapy.
Drug dosing for the tablet formulation should be determined using the dosing nomogram in 
Appendix II. For patients receiving powder for suspension (50 mg/mL), the dose will be rounded 
to the nearest 5 mg. Drug doses should be adjusted based on the BSA as determined by the height
and weight obtained within 1 week prior to the beginning of each cycle.
Pazopanib should be taken on an empty stomach (at least 1 hour before a meal or 2 hours after
a meal) at approximately the same time each day. Pazopanib tablets should be taken with clear
liquids (approximately 4 ounces for children < 12 years of age and 4-8 ounces for children ≥12
years of age). Pazopanib suspension should be taken according to instructions in Appendix VII.
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 72 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 (except where explicitly prohibited within the protocol). This does NOT apply to eligibility
requirements; but to therapy and evaluations post consent and post the start of protocol directed care. Novartis
will not grant protocol waivers.

The pazopanib suspension should be swirled for at least 30 seconds prior to removal of the dose 
from the bottle, which should be given immediately. If a patient vomits after a dose of pazopanib, 
the dose should not be repeated.
A patient diary (see Appendices IA and IB) should be completed by the patient or their guardian
and collected at the end of each cycle.
See Section 5 for Dose Modifications in Response to Toxicities
4.1.1
Dose Reduction
For patients who receive pazopanib tablets: Dose reduction(s) in response to toxicity
may be implemented according to guidance in Sections 5.2, 5.3, and 5.4 of the protocol.
Outside the specific management guidance described in these sections, patients who 
recover from an adverse event to starting criteria as outlined in Section 4.2 within 14
days following planned administration will also be permitted to receive protocol 
therapy at a reduced dose. Dose reduction(s) will be based on the starting dose and
should follow the Dosing Nomogram in Appendix II.
Note: For patients receiving pazopanib tablets at a starting dose of 400 mg, there will 
only be one allowed dose reduction due to tablet size.
For patients who receive pazopanib as oral powder for suspension:
Dose reduction(s) in response to toxicity may be implemented according to guidance 
in Sections 5.2, 5.3 and 5.4 of the protocol. Outside the specific management guidance
described in these sections, patients who recover from an adverse event to starting 
criteria as outlined in Section 4.2 within 14 days following planned administration will 
also be permitted to receive protocol therapy at a reduced dose. Dose reduction(s)
will be based on the starting dose and should follow the guidance in Table 1 and 
Table 1a.

4.1.2
Dose Escalation
Dose escalations will not be allowed.
4.1.3
Treatment Interruptions
If the protocol therapy has been interrupted for more than 14 days due to toxicity or 

Novartis
Confidential
Page 42
Amended Protocol Version 05 Clean
Protocol No. VEG116731
for reasons other than toxicity (unplanned travel or vacation, or lack of transportation 
to the site), the Study Chair must be notified to review the patient’s condition in order 
to resume treatment. In cases of toxicity, re-challenge at a reduced dose is possible if 
the patient’s condition has been stable and has not deteriorated and the patient must 
have recovered from the toxicity (Section 4.2).
If the protocol therapy has been interrupted for more than 28 days, the patient 
should be permanently discontinued from protocol therapy and will continue to be 
followed for survival.
4.1.4
Missed Doses
Missed doses should be documented in the electronic case report form (eCRF).
If a dose is missed, the patient should take the dose as soon as possible, but only if
there are 12 or more hours left before the next dose is due. If the next dose is due in
less than 12 hours, the patient should skip the missed dose and take the next dose
as scheduled.
4.1.5
Study Specific Supportive Care
4.1.5.1
Management of Hypertension: The algorithm in Section 5.4.1 will be used
to grade and manage pazopanib-related hypertension. Should initiation of
anti-hypertensive therapy be required, single agent therapy (commonly 
including the calcium channel blockers amlodipine or nifedipine, which are
permissible without notifying the Study chair) should be started and the blood
pressure should be monitored at least twice weekly until BP is within the
95th percentile for age, height, and gender per Section 5.4.1.
If patient is already on an anti-hypertensive medication at study enrollment, 
then their anti-hypertensive therapy should be adjusted (by either adjusting
the dose of their current anti-hypertensive medication or by adding another
anti-hypertensive agent) according to the algorithm in Section 5.4.1.
4.1.5.2
Management of Hypothyroidism: Patients with Grade 2 hypothyroidism 
should be evaluated by an endocrinologist for further management. Patients
with Grade 2 hypothyroidism adequately managed with thyroid hormone
replacement may continue on protocol therapy. Patients with Grade 3 or 
greater hypothyroidism attributable to pazopanib will be considered to have
had a dose-limiting toxicity. These patients should be managed according to
Section 5.3 and should also be evaluated by an endocrinologist for further
management. If Grade 3 or greater hypothyroidism
is 
adequately 
managed with thyroid hormone replacement and improves to grade 2 or less, 
pazopanib may be restarted.
4.1.5.3
Treatment of palmer-plantar erythrodysesthesia (Hand-foot syndrome): Oral
administration of vitamin B 6 (pyridoxine) may be considered for patients
who develop palmar-plantar erythrodysesthesia (hand-foot) syndrome:

BSA <0.5 m2: 50 mg per day

BSA 0.5-1.0 m2: 100 mg per day

BSA >1.0-1.5 m2: 200 mg per day

BSA >1.5 m2: 300 mg per day
Other supportive care measures for the treatment of hand-foot syndrome 
should be instituted as needed. If steroids are used, they must fall within the 

Novartis
Confidential
Page 43
Amended Protocol Version 05 Clean
Protocol No. VEG116731
dosing parameters in Section 4.8.
4.1.5.4
Blood-product Support: Patients should be supported with transfusion of 
blood and blood products (including platelet transfusion) per institutional 
standards.
4.1.5.5
SupportiveCare: General supportive care should be provided according to 
institutional standards. The COG Study Chair or Novartis Medical Lead can
be contacted for specific questions regarding supportive care.
4.2
Criteria for Starting Subsequent Cycles
A cycle may be repeated every 28 days if the patient has at least stable disease or progressive 
disease is ruled out based on clinical or laboratory evidence and
met the clinical and 
laboratory parameters as defined by the guidelines for dose modification and toxicity 
management (Section 5) and does not have a dose limiting toxicity requiring permanent
removal from protocol therapy (Section 5.1). A patient may resume protocol therapy at the
same or a reduced dose if they have a toxicity that is adequately managed (eg:
myelosuppression, hypertension, hepatotoxicity, electrolyte abnormality, bleeding, wound
healing, etc) as outlined in Sections 5.2, 5.3, and 5.4.
4.3
Concomitant Therapy
If new data become available showing an interaction between a concomitant medication and 
pazopanib that is considered significant enough to impact the risk/benefit balance of 
pazopanib, the list of permitted/prohibited medications in the Investigator Brochure will be 
updated either during the annual update or within an IB supplement. Any such changes will 
be communicated to the site via a letter which should be stored in the site’s study file.
4.4
Permitted Medications
All patients will be asked to provide a complete list of prescription and over-the-counter 
medications that have been taken within the previous 4 weeks prior to Screening. The 
investigator must be informed as soon as possible about any new medication(s) taken from 
the time of Screening until the completion of the post-treatment follow-up visit.
All concomitant medications taken during the study will be recorded in the eCRF with 
indication, dose information, and dates of administration.
Patients should receive full supportive care during the study, including transfusion of blood 
and blood products, treatment with antibiotics, analgesics, erythropoietin, or bisphosphonates, 
when appropriate.
Anti-emetics (such
as
prochlorperazine,
lorazepam, ondansetron
or
other 5-HT3 
antagonists) may be administered prophylactically in the event of nausea. However, it is 
important to note that 5-HT3 blockers that are given daily for a prolonged period of time 
may prolong QTc and should be used with caution. (Appendix IIIB). Anti-diarrheals, such 
as loperamide, may be administered as needed in the event of diarrhea. Although 
acetaminophen at doses of 2 g/day is permitted, it should be used with caution in patients 
with impaired liver function.
4.5
Permitted Medications – Use with Caution
4.5.1
Specific recommendations regarding anticoagulants:
Results from drug-drug interaction studies conducted in patients with cancer suggest

Novartis
Confidential
Page 44
Amended Protocol Version 05 Clean
Protocol No. VEG116731
that pazopanib has no effect on the metabolism of S-warfarin. Hemorrhagic events,
however, have been reported in clinical studies with pazopanib. Therefore, if the
investigator decides to continue pazopanib and anticoagulants use concomitantly, it
should be used with caution in patients with increased risk of severe bleeding or
who are benefitting from treatment and require the initiation of concomitant 
anticoagulant therapy (e.g., warfarin or its derivatives, low molecular weight heparin, 
unfractionated heparin) while on study. Note: Patients are excluded from enrolling
on the study if they are taking therapeutic doses of S-warfarin at the time of screening.
Patients taking concomitant anticoagulant therapy should be monitored regularly for
changes in relevant coagulation parameters as clinically indicated, as well as for any 
clinical bleeding episodes.
4.5.2
Specific recommendations regarding hypoglycemic therapy including insulin: 
Results from drug-drug interaction studies conducted in patients with cancer
suggest that there will be no clinically relevant pharmacokinetic interaction between 
pazopanib and hypoglycemic agents. Transient decreases in serum glucose (mainly
Grade 1 and 2, rarely Grade 3) have been observed in clinical studies with pazopanib. 
In addition, decreases in blood sugar have been reported in patients treated with 
another small molecule tyrosine kinase inhibitor, sunitinib (British Journal of Cancer
2008: 99, 1380). Such changes may require an adjustment in the dose of
hypoglycemic and/or insulin therapy. Patients should be advised to report symptoms
of hypoglycemia (e.g., confusion, visual disturbances, palpitations, and sweating). 
Serum glucose should be tested during treatment with pazopanib as outlined in the 
protocol and as clinically indicated.
4.5.3
Concomitant use of pazopanib and simvastatin increases the risk of ALT elevations 
and should be undertaken with caution and close monitoring. If a patient receiving 
concomitant simvastatin develops ALT elevations, follow dosing guidelines for 
pazopanib or consider discontinuing simvastatin.
4.5.4
Concomitant administration of pazopanib with esomeprazole decreases the 
bioavailability of pazopanib by 40% (AUC and Cmax). Co-administration of 
pazopanib
with
Proton Pump Inhibitors (PPIs)
should
be avoided.
Co-
administration of pazopanib with PPIs is PROHIBITED from 24 hours before
the first dose of pazopanib until after the final PK blood sample is collected on
Day 15 ± 1 day of Cycle 1. After this, if the concomitant use of a proton-pump
inhibitor (PPI) is medically necessary, it is recommended that the dose of pazopanib
be taken without food once daily in the evening concomitantly with the PPI (Section
4.8). If the concomitant administration of an H2-receptor antagonist is medically
necessary, pazopanib should be taken without food at least 2 hours before or at
least 10 hours after a dose of an H2-receptor antagonist. Pazopanib should be
administered at least 1 hour before or 2 hours after administration of short-acting 
antacids.
4.5.5
Concurrent Anti-Hypertensive Therapy: The algorithm in Section 5.4.1 will be 
used to grade and manage pazopanib related hypertension. Should initiation of 
anti-hypertensive therapy be required, single agent therapy (commonly including the
calcium channel blockers amlodipine or nifedipine) may be started without notifying 
the study chair.

Amended Protocol Version 05 Clean
Protocol No. VEG116731
4.5.6
Anti-inflammatory and anti-platelet agents (e.g. aspirin, and/or ibuprofen, or other 
NSAIDs) could result in elevated blood pressure or increased bleeding episodes 
when co-administered with pazopanib and therefore should be used with caution.
4.5.7
Patients’ medications should be reviewed at eligibility, before treatment initiation, 
and during treatment. Any concomitant medications that are “generally accepted” to
cause a risk of Torsade de pointes are prohibited (see Appendix IIIB). Those
“associated” with a risk of QTc prolongation and/or Torsades de pointes should be
discontinued or replaced with drugs that do not carry these risks, if possible.
Patients who must take these medications should be watched carefully for symptoms 
of QTc prolongation, such as syncope. Performing additional EKGs on patients who
must take one or more of these medications is recommended but not required, at the 
investigator’s discretion.
4.6
The Effects of Pazopanib on Other Drugs
In vitro data indicate that pazopanib is a potential inhibitor for CYP3A4, CYP2C8, CYP2D6,
CYP1A2, CYP2C9, CYP2C19, CYP2A6, CYP2B6, and CYP2E1. Pregnane X receptor 
transient transfection assay suggested some potential for human CYP3A4 induction at high 
concentrations. Results from drug-drug interaction studies conducted in patients with cancer
suggest that pazopanib is a weak inhibitor of CYP3A4, CYP2C8, and CYP2D6 in vivo, but 
had no clinically relevant effect on CYP1A2, CYP2C9 or CYP2C19 metabolism. Therefore, 
concomitant use of pazopanib with certain medications (substrates of CYP3A4, CYP2C8,
and CYP2D6) with a narrow therapeutic window should be undertaken with CAUTION due
to the potential for alterations in the pharmacologic effects of these medications or an
increased risk for serious or life- threatening adverse events associated with such medications
(see below) secondary to the inhibition of specific CYP enzymes by pazopanib. In addition,
the potential for drug interaction with such medications, although diminished, may persist
after the last dose of pazopanib due to its long half-life (i.e., mean 30.9 hours); therefore, 
continue to exercise CAUTION for at least 7 days and up to 15 days after the last dose of
pazopanib when administering these medications. These medications include (but are not 
limited to):

Ergot derivatives:
dihydroergotamine, ergonovine, ergotamine, methylergonovine 
(potential increased risk for developing ergot toxicity that includes severe vasospasm 
leading to peripheral as well as cerebral ischemia)

Neuroleptics: pimozide (potential increased risk for QT interval prolongation, 
ventricular arrhythmia, and sudden death)

Antiarrhythmics: bepridil, flecainide, lidocaine, mexiletine, amiodarone, quinidine, 
propafenone (potential increased risk for QT interval prolongation and Torsade de 
Pointes)

Immune modulators: cyclosporine, tacrolimus, sirolimus (potential increased risk for 
nephrotoxicity and neurotoxicity)

Miscellaneous: quetiapine, risperidone, clozapine, atomoxetine.
4.7
The Effects of Other Drugs on Pazopanib
Results from in vitro studies suggest that the oxidative metabolism of pazopanib in human 
liver microsomes is mediated primarily by CYP3A4, with minor contributions from CYP1A2
and CYP2C8. Furthermore, in vitro data suggest that pazopanib is a substrate for P-
glycoprotein and for breast cancer resistance protein. Substances that induce or inhibit 
CYP3A4 may alter the pharmacologic effects of pazopanib and should be used with 
CAUTION.

Novartis
Confidential
Page 46
Amended Protocol Version 05 Clean
Protocol No. VEG116731
Medications that inhibit CYP3A4 may result in increased plasma pazopanib concentrations. 
Co-administration of strong CYP3A4 inhibitors is prohibited (see Section 4.8); therefore 
selection of an alternate concomitant medication with no or minimal potential to inhibit 
CYP3A4 is recommended.
Medications that induce CYP3A4 may result in decreased plasma pazopanib concentrations 
and a loss of efficacy and therefore are prohibited (See Section 4.8). Anticonvulsant drugs 
that do not induce CYP enzymes are allowed. Refer to Appendix IIIA for a list of 
anticonvulsant drugs with little or no enzyme induction. The use of azithromycin or 
fluconazole is discouraged but allowed.
4.8
Prohibited Medications
Patients should not receive other anti-cancer therapy [cytotoxic, biologic, radiation, or 
hormonal (other than leuprolide or other GnRH agonists)] while on treatment in this study. 
Medications that inhibit CYP3A4 may result in increased plasma pazopanib concentrations; 
therefore, co-administration of strong CYP3A4 inhibitors is PROHIBITED beginning 14 
days prior to the first dose of protocol therapy until discontinuation of the protocol therapy. 
Strong CYP3A4 inhibitors include (but are not limited to):

Antibiotics: clarithromycin, telithromycin, troleandomycin, roxithromycin

HIV protease inhibitors: ritonavir, indinavir, saquinavir, nelfinavir, amprenavir, 
lopinavir

Antifungals: itraconzaole, ketoconazole, voriconazole

Antidepressants: nefazodone
CYP3A4 inducers may decrease plasma pazopanib concentrations. Selection of an alternate
concomitant medication with no or minimal enzyme induction potential is recommended.
Drugs that induce CYP3A4 and may decrease pazopanib plasma concentrations are
PROHIBITED and include (but are not limited to):

Glucocorticoids for greater than 2 weeks duration:
cortisone (>50 mg/day), 
hydrocortisone (>40 mg/day), prednisone (>10 mg/day), methylprednisolone (>8 
mg/day), dexamethasone (>1.5 mg/day)

Anticonvulsants: 
phenytoin, 
carbamezepine, 
phenobarbital, 
oxcarbazepine, 
primidone, fosphenytoin

HIV antivirals: efavirenz, nevirapine, tipranavir

Antibiotics: rifampin (rifampicin), rifabutin, rifapentene

Miscellaneous: St. John’s Wort, modafinil, pioglitazone
Grapefruit or grapefruit juice is prohibited as it inhibits CYP3A4 activity and may also 
increase plasma concentrations of pazopanib.
As noted above, co-administration of pazopanib with PPIs should be avoided and is
prohibited from 24 hours before the first dose of pazopanib until after the final PK blood 
sample is collected on Day 15 ± 1 day of Cycle 1.

DEFINITIONS AND DOSE MODIFICATION FOR TOXICITY
All dose modifications should be based on the worst preceding toxicity. The severity of adverse 
events will be graded utilizing the National Cancer Institute (NCI) CTCAE, version 4.
The cycle duration remains 28 consecutive days in patients who have dose interruption.
5.1
Definition of Dose Limiting Toxicity (DLT)
DLT will be defined as any of the following events that are at least possibly, probably, or
definitely attributable to pazopanib. See Section 5.4 for the Potential Pazopanib Specific 
Side Effects. Dose-limiting hematological and non-hematological toxicities are defined 
differently.
5.1.1
Hematological Dose-Limiting Toxicity
a) For patients who are evaluable for hematologic toxicity assessment (patients
without bone marrow involvement)

Grade 4 Thrombocytopenia (platelet count < 25,000/mm3) or Grade 4 
neutropenia

Any hematologic toxicity requiring dose reduction or treatment interruption 
for >14 days
b) For all patients:

≥Grade 2 arterial thromboembolic events (visceral arterial ischemia, 
peripheral ischemia, or ischemia cerebrovascular)

Grade 3 or 4 venous thromboembolic event

Any thrombotic event (other than central venous line [CVL] associated 
thrombosis) requiring systemic anticoagulation
5.1.2
Non-Hematological Dose-Limiting Toxicity
5.1.2.1
Any Grade 4 non-hematologic toxicity
5.1.2.2
Any Grade 3 non-hematological toxicity, with the specific exclusion of the 
following:

Grade 3 nausea and vomiting of less < 3 days duration

Grade 3 fever or infection,

Grade 
3 
hypophosphatemia,
hypokalemia,
hypocalcemia
or 
hypomagnesemia responsive to oral supplementation within 7 days
of start of supplement (see Section 5.4.4 for dose modifications)
5.1.2.3
Grade 2 allergic reactions that necessitate discontinuation of protocol 
therapy will not be considered a dose-limiting toxicity.
5.1.2.4
Any Grade 2 non-hematological toxicity that persists for ≥7 days and is 
considered sufficiently medically significant or sufficiently intolerable by
patients that it requires treatment interruption may also be considered a DLT
following discussion with the Study chair and a Novartis Medical Lead.
5.1.2.5
Hypertension will be graded according to the NCI CTCAE; however, 
dose limiting hypertension will be considered as the following:

Amended Protocol Version 05 Clean
Protocol No. VEG116731

Grade 4 hypertension

A blood pressure >25 mmHg above the 95th percentile for age, 
height, and gender (see Appendix V) confirmed by repeated
measurement on the same day (See Sections 5.4.1 and 4.1.5.1 for 
management)

In patients already on anti-hypertensive therapy due to previous 
hypertension (see Section 3.2.8.5), any blood pressure 1-25 mmHg
above the 95th percentile for age, height, and gender (Appendix V) 
for > 14 days (See Sections 5.4.1 and 4.1.5.1 for management)
5.2
Dose Modifications for Hematologic Toxicity
All dose modifications should be based on the worst preceding toxicity.
Pazopanib tablets: For step-wise dose reductions, see Appendix II for the dosing nomogram. 
Pazopanib powder in suspension: For step-wise dose reductions see Tables 1 and 1a (Section 
4.1.1).
5.2.1
For all patients:
If Grade 4 neutropenia occurs,                                                          
a)
Pazopanib should be held.
b)
CBCs should be checked at least twice a week (every 3 to 4 days)
until ANC ≥ 750/µL.
c)
Subsequent doses of pazopanib should be given at a reduced dose, when
ANC ≥750/µL.
If Grade 4 thrombocytopenia occurs,                                        
a)
Pazopanib should be held.
b)
CBCs should be checked at least twice a week (every 3 to 4 days) until
platelet count ≥75,000/L without need for platelet transfusion in the 
preceding 7 days.
Subsequent doses of pazopanib should be given at a reduced dose, when 
platelet count ≥ 75,000/L without need for platelet transfusion in the 
preceding 7 days.
5.2.1.1
If dose-limiting myelosuppression occurs as noted in Section 5.1.1,
a)
The dose of pazopanib should be resumed at a reduced dose, once
ANC ≥750/L and platelet count ≥75,000/L without need for 
platelet transfusion in the preceding 7 days.
5.2.2
For patients who have a dose limiting hematological toxicity that does not resolve to
the parameters defined in Section 5.2.1 within 14 days of holding pazopanib: if re-
challenge is to be considered the Study Chair must be contacted and provide approval 
prior to re-challenge.
5.3
Dose Modifications for Non-Hematological Toxicity
Specific instructions for the management of potential pazopanib side effects are included in
Section 5.4.

Novartis

Protocol No. VEG116731
5.3.1
For any non-hematologic dose limiting toxicity as detailed in Section 5.1.2:
a)
Pazopanib should be held
b)
If the non-hematologic DLT is a pazopanib specific toxicity, the dosing 
guidelines in Section 5.4 should be followed
c)
If the non-hematologic DLT returns to baseline within 14 days of holding 
pazopanib, subsequent doses of pazopanib should be given at a reduced dose.

If toxicity does not resolve to meet continued treatment parameters 
within 14 days of drug discontinuation, and if re-challenge is to be
considered, the Study Chair must be contacted as outlined in Section 4.2 
to discuss.

If DLT recurs in a patient who has resumed treatment after the maximum
allowed dose reductions, the patient must be removed from protocol
therapy, unless the patient has been approved for a further dose 
reduction following discussion with the Study Chair.
5.4
Potential Pazopanib Specific Side Effects
5.4.1
Hypertension

Baseline blood pressure (BP) is defined as the blood pressure obtained at the
examination used for study enrollment. This baseline BP should be obtained as 
follows:
1)
Obtain 3 serial blood pressures from the same extremity with the patient in
the same position that are separated by at least 5 minutes. Avoid using the 
lower extremity if possible.
2)
Average the systolic blood pressure from the 2nd and 3rd measurements.
3)
Average the diastolic blood pressure from the 2nd and 3rd measurements.
4)
The baseline BP is the average of the systolic over the average of the 
diastolic measurements.

Elevation in either the systolic or diastolic blood pressure should be considered 
when following the algorithm below.

The upper limit of normal (ULN) is defined as a BP equal to the 95th
percentile for age, height, and gender. If ≥ 18 yrs of age, ULN will be defined 
as a BP of 140/90. See Appendix V.

The NCI CTCAE version 4.0 will be utilized to determine the grade of 
hypertension for reporting purposes.

Elevated BP measurements should be repeated on the same day to confirm the
elevation. Patients with an elevated BP should have BP measurements performed 
at least twice weekly until BP is ≤ ULN.

The algorithm below will be used to manage pazopanib related hypertension.

Hypertension should be managed with appropriate anti-hypertensive agent(s) as 
clinically indicated. It is strongly recommended that nephrology or cardiology be 
consulted in the evaluation and management of hypertension.

For patients who were on one anti-hypertensive medication at study enrollment 
and hypertension worsens while on study, further anti-hypertensive therapy may
include dose adjustment of the current medication or the addition of a second 
anti-hypertensive medication.

Arm 1 of algorithm:

If blood pressure (BP) ≤ 95%ile for age, height, and gender: continue 
pazopanib at the same dose.
Arm 2 of algorithm:

If BP ≤10 mm Hg above the ULN: continue pazopanib at the same dose and 
recheck the BP within 72 hours.
o
If the BP is ≤ ULN on recheck, continue pazopanib at the same dose.
o
If the BP remains above the ULN on recheck, then start/adjust
antihypertensive therapy (Section 4.1.5.1) and follow Arm 3 of the
algorithm from the point that anti-hypertensive therapy is started/adjusted.
Arm 3 of algorithm:

If BP is 11 to 25 mm Hg above the ULN on ≥2 of 3 measurements or
> 35 mmHg above baseline on ≥2 of 3 measurements, start/adjust anti-
hypertensive therapy (see Section 4.1.5.1) and continue pazopanib at the 
same dose. Monitor BP at least twice weekly.
o
If the BP returns to ≤ULN within 14 days, continue pazopanib at the 
same dose and continue anti-hypertensive therapy.
o
If the BP remains elevated ≥25 mm Hg above the ULN or > 35 mm
Hg above baseline for more than 14 days after the institution/adjustment
of anti-hypertensive therapy, hold pazopanib, monitor BP at least
every 3 days, and follow Arm 4 of the algorithm from the point that
pazopanib is held. The anti-hypertensive therapy should be continued 
until the BP is less than the ULN.

If the BP returns to ≤ULN within 14 days, restart pazopanib at a reduced


If the BP remains > ULN for more than 14 days, patient must be removed 
from protocol therapy.
o
If the BP increases to > 25 mm Hg above the ULN despite anti-
hypertensive therapy, hold pazopanib, but continue the anti-hypertensive 
agent(s). Monitor the BP as clinically indicated and follow Arm 4 of the 
algorithm from the point that pazopanib is held.

If the BP is ≤ULN within 14 days, pazopanib may be restarted at a reduced 
dose.

If the BP is > ULN for > 14 days, the patient must be removed from protocol 
therapy (Section 8.1).
Arm 4 of algorithm:

If BP is > 25 mm Hg above the ULN hold pazopanib, monitor BP, and 
administer/adjust anti-hypertensive therapy as clinically indicated.
o
If the BP returns to ≤ ULN within 14 days, pazopanib may be restarted 
at a reduced dose.
o
If the BP is > ULN for >14 days, the patient must be removed from 
protocol therapy (Section 8.1).
Arm 5 of algorithm:
If the participant develops Grade 4 hypertension, discontinue pazopanib, monitor
BP and administer anti-hypertensive therapy as clinically indicated. A nephrology
and/or cardiology consult is recommended. The patient must be removed from
Protocol Therapy (Section 8.1).
5.4.2
Abdominal pain:
Abdominal pain is a common symptom with vascular endothelial growth factor 
(VEGF) receptor antagonists such as pazopanib. Bowel perforations have
been reported in clinical trials of pazopanib and with other agents in this class.
Bowel perforations have been associated in some patients with tumor in the
bowel wall, or diverticulitis, while in others there has been no clear explanation.
Although bowel perforation is a rare event, investigators and study staff at
the site are advised to be vigilant of this potential complication in patients 
receiving pazopanib. Abdominal complaints should be assessed during AE
review at every visit. In addition, every physical exam should include a
complete abdominal exam. For patients with abdominal complaints and/or
abnormal findings on clinical exam, follow the dose modifications and 
evaluations described below.

or monospot testing)

Liver imaging (Ultrasound)
3.
Monitor patient closely for clinical signs and 
symptoms
4.
Perform LFTs1 weekly (or more frequently if 
clinically indicated) until ALT reduced to <
Grade 1
5.
Pazopanib may be held for up to 14 days, if ALT 
returns to <  Grade 1 and patient is benefitting 
from treatment, pazopanib may be resumed at a 
reduced dose following Novartis / Study Chair
approval (contact the Sponsor Medical Lead
and the Study Chair via email or phone to 
start the approval process). If approval for re-
treatment is granted, the patient must be re-
consented (with a separate informed consent) 
specific to hepatotoxicity.

For patients on tablets dose reductions are as 
follows:
o
If on 800 mg, then reduce to 400 mg 
daily
o
If on 600 mg, then reduce to 400 mg 
daily
o
If on 400 mg, reduce to 200 mg daily

For patients on powder suspension:

weekly or more frequently if clinically 
indicated until LFTs are reduced to 
Grade 1.
For isolated total bilirubin2 elevation without
concurrent ALT increase (defined as Grade 1 ALT
≤3 x ULN).
1.
Isolated hyperbilirubinemia (in the absence of 
elevated ALT or other signs/symptoms of liver 
injury) does not require dose modification.
Study treatment inhibits UGT1A1 and
OATP1B1, which can cause elevation of
indirect (unconjugated) bilirubin in the absence 
of liver injury
2.
If total bilirubin is >1.5 ULN in the absence of 
ALT elevation, fractionation of bilirubin should 
be performed. 

If the bilirubin is predominantly indirect 
(≥65%) indirect (unconjugated), continue 
study treatment at the same dose.

If bilirubin is >35% direct (conjugated), 
study treatment may also be continued 
however, further evaluation should be 
undertaken for underlying cause of 
cholestasis.
1LFTs include: AST, ALT, alkaline phosphatase, GGT and total bilirubin.
2Serum bilirubin fractionation should be performed if testing is available. If testing is unavailable and a
patient meets the criterion of total bilirubin > 1.5 x ULN, then the event should be promptly reported as defined.
3When a liver chemistry event meets the Liver Event Interruption Criteria, or Liver Event Stopping Criteria,
blood samples should be obtained for clinical laboratory testing by the central laboratory (Liver Event
Kits will be provided for this purpose).
4These extra tests will be performed centrally
5.4.4 Electrolyte Abnormalities:
Serum K+, Ca++, Mg++, phosphate levels should be monitored given the risk of 
prolonged QTc. If serum Ca++ is abnormal, ionized calcium should be obtained and 
interventions based on ionized calcium only.
Pazopanib should be held and an EKG obtained for


Hypokalemia or hyperkalemia ≥ Grade 2

Hypocalcemia or hypercalcemia ≥ Grade 3

Hypophosphatemia or hyperphosphatemia ≥ Grade 3

Hypomagnesemia or hypermagnesemia ≥Grade 3
These laboratory values should be corrected as soon as possible in a manner 
consistent with good medical judgment. Pazopanib may be resumed at a reduced dose 
when:

Hypokalemia or hyperkalemia is Grade 1 or within institutional limits

Hypocalcemia or hypercalcemia is ≤ Grade 2

Hypophosphatemia or hyperphosphatemia is ≤ Grade 2

Hypomagnesemia or hypermagnesemia is ≤ Grade 2.
Even though pazopanib administration is allowed at these lower laboratory toxicity
grades, every effort should be made to correct the abnormal lab values to normal if 
possible.
5.4.5 Proteinuria:

If urinalysis shows ≥trace protein then obtain a urine protein: creatinine 
ratio (UPC).

If the UPC is ≥ 1, then obtain a 24-hour urine collection for protein 
estimation.

If the urine protein is ≥3.5 g/24-hours then hold pazopanib and re-
assess urine protein weekly.

If the urine protein decreases to < 3.5 g/24 hours in < 21 days then
resume pazopanib at a reduced dose.

Monitor the 24 hour urine protein or UPC weekly for 2 consecutive
weeks once pazopanib is resumed.

If pazopanib is held for ≥28 days then the patient must be removed
from protocol therapy.

QT Prolongation:
Guidelines for the management of prolonged QT interval are as follows: 
Measure the QT interval (from the start of the Q wave to the end of the
T wave) and the preceding RR interval. The corrected QT interval using 
the Bazett’s formula (QTcB interval) will be calculated as the QT
interval (msec) divided by the square root of the RR interval (msec).
Only the Bazett’s formula should be used to calculate the corrected QT
interval.

QTcB interval < 500 msec: No specific therapy needed.
Continue pazopanib at the same dose. Serum K+, Ca++, Mg++, and Phos 
should be monitored and repleted if low (see Section 5.4.4).

QTcB interval ≥500 msec: Hold pazopanib, review concomitant 
medications, and replete serum K+, Ca++, Mg++, and Phos as needed.
The EKG should be repeated within 7 days and if the QTcB interval 
is < 500 msec then resume pazopanib at a reduced dose. If the QTcB 
interval remains ≥500 msec, the patient must be removed from
protocol therapy.
5.4.7 Delays in Wound Healing:
Patients treated with VEGF blocking agents appear to have an increased risk of 
wound healing complications. Therefore, if patients require elective major surgery
on study, pazopanib should be held for 14 days prior to surgery and for 14 days
after surgery (see Section 3.3.7). Pazopanib should not be restarted if there is
evidence of wound healing complications such as a wound infection. Patients who 
require surgery less than 14 days from treatment with pazopanib should be 
monitored closely for wound complications. Patients who require major surgery 
during Cycle 1 of therapy must be removed from protocol therapy.

DRUG INFORMATION
6.1
PAZOPANIB
(VotrientTM, GW786034, Pazopanib HCl, GW786034B (monohydrochloride salt)) 
NSC# 737754, IND# 065747
Source and Pharmacology:
The 
chemical 
name 
for 
pazopanib 
is 
5-[[4-[(2,3-Dimethyl-2H-indazol-6-
yl)methylamino]-2-pyrimidinyl]amino]-2-methylbenzenesulfonamide 
monohydrochloride. The molecular formula is C21H23N7O2S-HCl. The molecular
weight is 474.0 (monohydrochloride salt) and 437.5 (free base). The monohydrochloride
salt is very slightly soluble in 0.1 M HCl (0.65 mg/mL), practically insoluble in pH 7.0
phosphate buffer (0.00005 mg/mL), and practically insoluble in pH 11 piperidine buffer
(0.0002 mg/mL).
Pazopanib is a multi-targeted inhibitor of vascular endothelial growth factor (VEGF) 
receptor tyrosine kinases (VEGFR1, VEGFR2, and VEGFR3), platelet-derived growth 
factor receptor kinases (PDGFR-α and –β), fibroblast growth factor receptor-1 and -3, 
cytokine receptor (Kit), interleukin-2 receptor inducible T-cell kinase (Itk), leukocyte-
specific protein tyrosine kinase (Lck), and transmembrane glycoprotein receptor 
tyrosine 
kinase
(c-Fms). 
In
vitro,
pazopanib
inhibited
ligand-induced
autophosphorylation of VEGFR-2, Kit and PDGFR-β receptors. In vivo, pazopanib 
inhibited VEGF-induced VEGFR-2 phosphorylation in mouse lungs, angiogenesis in a
mouse model, and the growth of some human tumor xenografts in mice.
In adults, pazopanib is orally absorbed with median time to peak concentration of 2
to 4 hours after the dose. Also in adults, the administration of a single, crushed
pazopanib 400 mg tablet increased AUC(0-72) by 46%, increased Cmax by
approximately 2 fold, and decreased Tmax by approximately 2 hours compared to
administration of the whole tablet. Due to this potential for increased exposure
(increased bioavailability, increased rate of absorption), tablets of pazopanib should
not be crushed. Systemic exposure is increased when pazopanib is administered with
food. Administration with a high-fat or low-fat meal results in an approximately 2-fold
increase in AUC and Cmax. Therefore, pazopanib should be administered at least 1 
hour before or 2 hours after a meal. Pazopanib is more than 99% bound to human
plasma protein in vivo. In vitro studies suggest that pazopanib is a substrate for P-
glycoprotein (Pgp) and breast cancer resistant protein (BCRP).
In vitro studies demonstrated that pazopanib is metabolized by CYP3A4 with a minor 
contribution from CYP1A2 and CYP2C8. In vitro data also indicate that pazopanib is
an inhibitor for CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1,

Protocol No. VEG116731
and CYP3A4 with its most potent inhibition for the isoenzyme CYP2C9. In vivo,
however, pazopanib is a weak inhibitor of CYP3A4, CYP2C8, and CYP2D6 with no
effect on probes for CYP2C19, CYP2C9, and CYP1A2. Therefore, medications that
are potent inducers or inhibitors of CYP3A4 are prohibited (refer to Section 4.8).
Washout periods are specified in Sections 4.6, 4.7 and 4.8. If not specifically mentioned, 
it is at the discretion of the clinician based on the pharmacokinetic properties of each
individual agent. Concomitant use of pazopanib with agents with narrow therapeutic 
windows that are metabolized by CYP3A4,
CYP2C8,
or
CYP2D6

recommended. Coadministration may result in inhibition of the metabolism of these 
products and create the potential for serious adverse events.
In adults, pazopanib has a mean half-life of 30.9 hours after administration of the 
recommended dose of 800 mg. Elimination is primarily via feces with renal
elimination accounting for <4% of the administered dose. Based on baseline hepatic
function, 800 mg pazopanib is recommended for adult patients with mild impairment 
(defined as either normal bilirubin and any degree of alanine aminotransferase [ALT]
elevation or as an elevation of bilirubin up to 1.5x upper limit of normal [ULN]
regardless of the ALT value), and 200 mg for adult patients with moderate impairment
(defined as an elevation of bilirubin >1.5 to 3xULN regardless of the ALT values). The
maximum dose of pazopanib (200 mg) administered to adult patients with severe 
hepatic impairment did not achieve therapeutic plasma concentrations. Therefore,
pazopanib is not recommended in adult patients with severe hepatic impairment 
(defined as total bilirubin >3xULN regardless of any level of ALT).
Pazopanib may cause prolongation of the QT interval and torsades de pointes. Refer
to Appendix IIIB for agents to avoid during administration of pazopanib.
Pregnancy and lactation: 
Pregnancy Category D
Pazopanib can cause fetal harm when administered to a pregnant woman. Based on its 
mechanism of action, pazopanib is expected to result in adverse reproductive effects.
In pre-clinical studies in rats and rabbits, pazopanib was teratogenic, embryotoxic, 
fetotoxic, and abortifacient. In pre-clinical studies in rats and rabbits, pazopanib was
teratogenic, embryotoxic, fetotoxic, and abortifacient. Administration of pazopanib
to pregnant rats during
organogenesis
at
a
dose
level
of
≥3 mg/kg/day
(approximately 0.1 times the human clinical exposure based on AUC) resulted in
teratogenic
effects
including cardiovascular malformations (retroesophageal 
subclavian artery, missing innominate artery, changes in the aortic arch) and 
incomplete or absent ossification. In addition, there was reduced fetal body weight, and
pre- and post-implantation embryolethality in rats administered pazopanib at doses ≥
3 mg/kg/day. In rabbits, maternal toxicity (reduced food consumption, increased
post-implantation loss, and abortion) was observed at doses ≥30 mg/kg/day
(approximately 0.007 times the human clinical exposure). In addition, severe 
maternal body weight loss and 100% litter loss were observed at doses ≥100 mg/kg/day 
(0.02 times the human clinical exposure), while fetal weight was reduced at doses ≥3 
mg/kg/day (AUC not calculated).
There are no adequate and well-controlled studies of pazopanib in pregnant women. 
Protocol therapy should be immediately discontinued if pregnancy occurs while the 
patient is on therapy. Women of childbearing potential should be advised to avoid 
becoming pregnant while taking pazopanib and for up to 30 days after stopping 
pazopanib.

Formulation and Stability:
Tablets
Pazopanib is supplied as a series of aqueous film-coated tablets containing, 200 mg, and
400 mg of the free base:

200 mg, oval-shaped, white, packaged in bottles containing 34 tablets each

400 mg, oval-shaped, white, packaged in bottles containing 68 tablets each
Tablet excipients in all tablet sizes include microcrystalline cellulose, povidone, sodium 
starch glycolate, and magnesium stearate. The film coating consists of titanium dioxide, 
hypromellose, polyethylene glycol, and polysorbate 80. Store the intact bottles at
controlled room temperature (20ºC-25ºC). Excursions are permitted between 5ºC and
25ºC. Do not store pazopanib tablets above 25ºC.
Pazopanib Suspension (to be prepared in pharmacies)
Pazopanib Powder for Oral Suspension is a white to slightly colored powder supplied to
the clinical sites in amber glass (USP Type III) bottles with child-resistant closures. Each
bottle contains 5 grams of pazopanib.
Pazopanib Powder for Oral Suspension should be reconstituted with 90 mL of sterilized
or purified water to provide a white oral suspension containing 50 mg/mL of GW786034
as free base as detailed below.
1. Tap the sides to the bottle to loosen the powder.
2. Add 90 mL of room temperature sterilized or purified water for injection to the 
bottle.
3. Replace the cap tightly and shake vigorously by inversion for at least 2 minutes to 
ensure complete powder reconstitution.
4. Allow the bottle to sit for at least 3 minutes to allow any foam to dissipate.
Suspension is then ready for use as a white, lemon-flavored, 50 mg/mL suspension.
Pazopanib oral suspension should be stored refrigerated (2o-8o C). Do not freeze. The 
powder suspension is designed for multiple use and may be used for up to 35 days when 
refrigerated (2o-8o C).
Guidelines for Administration: See Treatment and Dose Modification sections of the 
protocol. Also, see Appendix VII for Patient Instructions for Pazopanib suspension.
Pazopanib should be taken on an empty stomach at least 1 hour before or 2 hours after a 
meal. The tablets should be swallowed whole and cannot be crushed or broken.
Avoid concomitant strong CYP3A4 inhibitors as these may increase pazopanib 
concentrations. Avoid concomitant strong CYP3A4 inducers as these may decrease

pazopanib concentrations. Refer to Sections 4.5, 4.6, 4.7 and 4.8 for agents that should 
be avoided or used with caution. The consumption of grapefruit and its juice are not 
allowed for the duration of treatment with pazopanib. Concomitant use of pazopanib 
with agents with narrow therapeutic windows that are metabolized by CYP3A4,
CYP2D6, or CYP2C8 is not recommended.
If a dose is missed, refer to section 4.1.4 Missed doses. If a patient vomits the 
dose, do not repeat the dose.
Dosing Instructions for Pazopanib (50mg/mL) multiple use oral powder suspension:

Insert a Baxa 28 mm Press-In-Bottle Adapter (PIBA®) (these supplies will be
provided to the site by Novartis) into the neck of the bottle. Check to ensure that
the lip of the Adapter fits snugly with the top of the bottle.

Swirl gently for at least 30 seconds to ensure homogeneity of the suspension 
immediately prior to the removal of the required dose for administration.

Remove the required dose using a suitable graduated syringe (recommend
Exacta- Med® Baxa) as follows:
1.
Ensure that the syringe plunger is fully pushed into the barrel.
2.
Insert the syringe tip into the Adapter, then invert the bottle and dispense
at least 5 mL of suspension into the syringe and then pump the entire
suspension back into the bottle to purge the syringe of any air bubbles.
Repeat this step until the syringe is free from air bubbles.
3.
Withdraw the required dose. Then re-invert the bottle and remove the
syringe from the Adapter and administer the dose as soon as possible.

investigational product dispensed and/or 
administered to study patients, the amount returned by study patients (if applicable),
and the amount received from Sponsor and, when applicable, the amount returned to
Novartis. Product accountability records must be maintained throughout the course of 
the study.
After completion of the study, a final inventory of accountability records and
unused study medications will be performed by the study monitor and site personnel.
A record of the number of tablets dispensed to and returned by each patient at each
visit must be maintained and reconciled with the study medication and compliance

records in the eCRF. At each site visit, the cause of any missed doses should be
discussed and documented.
A record of the number of milligrams (determined by weight) of pazopanib in
oral powder suspension dispensed to and returned by each patient at each visit must be 
maintained and reconciled with the study medication and compliance records in
the eCRF. At each site visit, the cause of any missed doses should be discussed and 
documented.
After completion of the study, a final review of accountability records and inventory
of unused study medications will be performed by the study monitor and site
personnel. If the site has received documented approval from Sponsor, unused study
medication may be destroyed, prior to inventory by the study monitor. In this case,
the study monitor would review only study medication accountability records at the
end of study visit. Additional information on the drug accountability process is
provided in the Study Procedure Manual.
Any AE(s) associated with missed doses must be recorded in the eCRF. Patients
should be instructed for the importance of compliance to study treatments.
Agent Destruction:
If allowed per site policy and procedures, unused study medications will be destroyed 
according to site-specific guidelines and proof of destruction will be forwarded to
Novartis.

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 72 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 (except where explicitly prohibited within the protocol). This policy does NOT apply to eligibility
requirements; but to therapy and evaluations post consent and post the start of protocol-directed care. Novartis

1.
Window for assessment is Day 25-28 of the preceding cycle for any assessment with the exception of disease 
evaluations. See footnote 12 for assessment window on disease evaluation.
2.
Should be performed, if possible, at the time the patient comes off protocol therapy regardless of the reason, unless the 
test or procedure has been performed within the past 2 weeks.
3.
Blood pressures will be measured with an appropriate sized cuff at rest. Blood pressure measurement will be repeated 
within the same day if the blood pressure (BP) is elevated (> the 95th percentile for age, height, and gender). If both BP 
measurements are > 95th percentile for age, height, and gender, follow the guidelines in Section 5.4.1. Patients with 
elevated BP (that is, BP greater than the 95th percentile for age, height, and gender) at any time should have BP 
measurements performed at least twice weekly until BP is within the 95th percentile for age, height, and gender (see
Appendix V). Guidelines for the grading and management of hypertension are in Section 5.1.2.5, 5.4.1, and Appendix V.
4.
Evaluations obtained for screening will ONLY be repeated at Cycle 1 Day 1 if they are older than 7 days.
5.
If patients have Grade 4 neutropenia, then CBCs should be checked every 3 to 4 days until recovery to Grade ≤3.
6.
If patients have Grade 3 or 4 thrombocytopenia, then CBCs should be checked twice a week until recovery to Grade ≤2.
7.
If patient has LFT elevation, monitor LFTs as described in Section 5.4.3.

8.
Patients found to have an abnormal TSH level at baseline and/or at subsequent visits should have a free T4 level 
measured (See Section 7.2.2). Management of hypothyroidism is described in Section 4.1.5.2.
9.
See Appendix IV for UPC rationale and calculation and Section 5.4.5 for dose modifications if UPC ≥1. UPC
assessment is adequate to follow-up prior proteinuria. If a 24-hour urine for protein is obtained, UPC is not required.
10. A confirmatory disease evaluation should be obtained, if possible, on the next consecutive cycle after initial 
documentation of either a PR or CR. This confirmatory evaluation is in addition to the schedule as noted (eg: if 
confirmatoryscans are done prior to Cycle 4, the next disease evaluation should be done as scheduled prior to Cycle 5)
11. Bone marrow evaluation to be done only in patients with known marrow involvement.
12. Disease evaluation should be performed during Days 24 – 28 of the cycle for the first 2 assessments (prior to Cycles 3 
and 5) and during Days 21 – 28 of subsequent indicated cycles. Patients who achieve a PR or CR should undergo the
appropriate disease evaluation on the next consecutive cycle after initial documentation of either a PR or CR. If the
institutional investigator determines that the patient has progressed based on clinical or laboratory evidence, the 
investigator can remove the patient from protocol therapy, he/she may opt not to confirm this finding radiographically. ; 
however an end of study disease assessment should be completed.
13. For hepatoblastoma patients only – perform no more than 48 hours prior to starting treatment on Day 1 of Cycle 1 (results do
not need to be known) and then with each disease evaluation if the initial value is elevated.
14. For neuroblastoma patients only - VMA = vanillylmandelic acid; HVA = homovanillic test.
15. Females of childbearing potential require a negative serum pregnancy test prior to starting treatment. Patients of 
childbearing potential must use an acceptable method of birth control. Abstinence is an acceptable method of birth 
control.
16. See Section 5.4.6 for dose modifications regarding Left ventricular systolic dysfunction or decrease in shortening fraction.
17. More frequent EKG monitoring is recommended for patients receiving drugs “associated” with Torsades de pointes (See 
Appendix IIIB) and required for Grade 2 potassium and Grade 3 calcium (confirmed by ionized calcium), magnesium 
and phosphorous abnormalities. See Sections 5.4.4 and 5.4.6.2.
18. Plain radiographs of at least one tibial growth plate should be obtained in all patients prior to the first dose of protocol 
therapy. In patients with open growth plates, follow-up plain radiographs of the same growth plate(s) should be obtained 
according to Section 7.2.1.
19. See Section 7.3 for timing of required PK sampling, and Appendix VI for the PK worksheet. No PK samples are required 
beyond Cycle 11

Monitoring for Specific Toxicities
7.2.1
Growth Plate Toxicity
Patients will have a plain AP radiograph of a single proximal tibial growth
plate obtained prior to the first dose of protocol therapy.
a. If patients are found to have a closed tibial growth plate, no further 
radiographs will be required.
b. If patients are found to have an open tibial growth plate, then repeat plain 
AP radiographs of the same tibial growth plate will be obtained prior to
starting Cycle 2, Cycle 5 and then every 6 months (prior to cycle 11, 17, 
etc).

Patients with evidence of growth plate thickening or other changes 
should have a knee MRI performed to further assess the degree of
physeal pathology and undergo more frequent x-ray follow up. MRI
should be performed without contrast. If no MRI changes are seen,
x- rays may be performed approximately every 2 months.

Patients with knee MRI changes should be managed in an individualized
manner. Decisions regarding continuation of pazopanib should take into 
account the presence of any symptoms referable to the knee as well
as the patient’s response to pazopanib. Consultation with an orthopedic
surgeon may also be indicated. Plans for follow-up imaging will also be 
made on an individualized basis, taking into account the presence of 
symptoms at the knee or other joints as well as the decision to continue 
pazopanib or not. Consultation with orthopedics and with the Study 
Chair is advised.
7.2.2
Thyroid Toxicity
Patients will have a TSH level measured prior to initial treatment, prior to 
starting Cycle 3, 5, and then every 3rd cycle thereafter (eg: prior to Cycle
8, Cycle 11, etc). Patients found to have an abnormal TSH level should have
a free T4 level measured. Thyroid toxicity will be handled like any other non-
hematological toxicity. Guidance on the management of patients who develop 
hypothyroidism is included in Section 4.1.5.2.
7.2.3
Cardiac Toxicity
Patients will have a baseline echocardiogram and EKG obtained pre-treatment, 
prior to Cycles 2 and 5, and then every 6 months (prior to Cycle 11, 17, etc)
and as clinically indicated. See Section 5.4.6 for management of changes
in left ventricular function and prolonged QTcB while on protocol therapy.
7.2.4
Pregnancy Testing and Reporting
The need for a screening pregnancy test depends on whether a female patient
is of childbearing potential or non-childbearing potential. If a female patient is
of childbearing potential, she must have a serum -Human Chorionic
Gonadotropin (-HCG) pregnancy test performed within 7 days prior to the
first dose of study treatment(s). Patients with a positive pregnancy test result 
must be excluded from the study. Patients with a negative pregnancy test result
must agree to use an adequate contraception method as described below during
the study until 2 weeks following the last dose of study treatment(s). Any
pregnancy that occurs during study participation must be reported using a
clinical trial pregnancy form. To ensure patient safety, each pregnancy must 

Novartis
Confidential
Page 70
Amended Protocol Version 05 Clean
Protocol No. VEG116731
be reported to Novartis within 24 hours of learning of its occurrence. Study 
treatment should be immediately discontinued if pregnancy occurs during
study participation. The pregnancy must be followed up to determine outcome 
(including premature termination) and status of mother and child. Pregnancy
complications
and
elective
terminations
for
medical
reasons must be 
reported as an AE or SAE (Section 11.8). Spontaneous abortions must be 
reported as an SAE.
Any SAE occurring in association with a pregnancy brought to the
investigator’s attention after the patient has completed the study and
considered by the investigator as possibly related to the study treatment(s) must 
be promptly reported to Novartis.
Any SAE occurring as a result of a post-study pregnancy which is considered 
reasonably related to the study treatment by the investigator, will be reported 
to the Sponsor. While the investigator is not obligated to actively seek this 
information in former study participants, he or she may learn of an SAE
through spontaneous reporting.
In addition, the investigator must attempt to collect pregnancy information
on any female partners of male study subjects who become pregnant while
the subject is enrolled in the study. Pregnancy information must be reported to
Novartis as described above.
7.3
Pharmacokinetic studies
7.3.1
Description of Studies and Assay
Plasma samples will be collected and analyzed for pazopanib levels using a 
validated LC/MS/MS (Liquid Chromatography/Tandem Mass Spectrometry) 
method under the control of Novartis.
7.3.2
Sampling schedule:
All patients (whether receiving pazopanib as tablet or as oral powder 
suspension) will have a blood sample for analysis of the plasma pazopanib
concentration collected prior to the first dose on Day 1 of Cycle 1. In addition, 
all patients will have 2 blood samples collected on Day 15 ± 1 day of Cycle
1: one sample prior to the dose and one sample 3-4 hours after dosing.
Blood samples for analysis of steady-state trough plasma pazopanib 
concentrations will also be obtained prior to the start of every subsequent odd-
numbered cycle (that is, pre-dose prior to Cycle 3, pre-dose prior to Cycle 5, 
etc). These steady-state trough plasma concentration samples can be collected 
between Day 22 of the previous cycle to Day 1 of the odd-numbered cycle,
and the actual date and time of sample collection recorded on the PK sample 
collection form. No PK samples are required beyond Cycle 11.
The pre-dose sample on Day 15 ± 1 day of Cycle 1 and the trough plasma 
concentration samples taken prior to dosing for every odd-numbered cycle 
should be obtained between 22-26 hours after the previous dose of 
pazopanib. Patients should be instructed to hold their dose of pazopanib on
the day that a pre-dose PK sample is to be collected. Collection of these PK
samples should correspond to the timing of routine laboratory evaluations.

Novartis
Confidential
Page 71
Amended Protocol Version 05 Clean
Protocol No. VEG116731
Extended PK sampling will be done during Cycle 1 in the first patients who 
receive the powder suspension formulation, until 6 patients are considered 
evaluable for the PK analysis. These patients will have a blood sample for 
analysis of the plasma pazopanib concentration collected at the following
time points on Day 1 of Cycle 1: pre-dose and at 30 min, 1 hour, 2 hours, 4
hours, 6 hours, and 8 hours after the dose. Samples will also be obtained on
Day 15 ± 1 day of Cycle 1: pre-dose and at 30 min, 1 hour, 2 hours, 4 hours,
6 hours, and 8 hours after the dose. If one or more of these 6 patients fail to
provide blood samples as specified in the protocol or if it is known that for 
some reason a patient’s collected blood sample(s) cannot be analyzed, that 
patient(s) will be determined to be non-evaluable for this analysis and one or
more additional patients will be enrolled for treatment with pazopanib as
powder for oral suspension and provision of the extended PK samples. These
patients will also provide blood samples for analysis of steady-state trough
plasma pazopanib concentrations prior to the start of every subsequent odd-
numbered cycle as described in the preceding paragraph.
Pazopanib dosing of either tablet or powder suspension must have continued 
uninterrupted and at the same dose level for at least 10 days prior to
acquisition of the Cycle 1 Day 15 PK samples. If pazopanib dosing has been
interrupted or modified <10 days prior to Cycle 1 Day 15, then the PK samples
should be taken between Cycle 1 Day 15 and Cycle 1 Day 22 on a study day
that meets the condition of at least 10 consecutive days of dosing at the same
dose level. The Cycle 1 Day 15 PK kit should be used and the actual date and 
time of sample collections should be recorded in the eCRF.
If ≥2 out of 6 evaluable patients have dose-limiting toxicities as defined in 
Section 5.1) during the first cycle, then enrollment at the 225 mg/m2/dose dose 
level of pazopanib oral suspension will be halted. Subsequent new patients
will be enrolled at the 160mg/m2/dose level until 6 evaluable patients from this
dose group are available for the safety review and 6 patients are available for
PK analysis.
7.3.3
Sample Collection and Handling Instructions:
Blood samples (2 mL for each sample) will be collected for PK into tubes 
containing potassium EDTA as an anticoagulant. See the corresponding
Pharmacokinetic Study Form (Appendix VI) for specific details of Sample 
Collection, Processing, Handling, and Shipping.
7.3.4

Survival follow-up:
The following information will be collected and reported every 3 months:

Survival status

Antineoplastic therapies taken since discontinuation of protocol therapy
The primary reason protocol therapy was permanently discontinued must be documented
in the patient’s medical records and eCRF. If the patient discontinues from protocol
therapy due to toxicity, AE will be recorded as the primary reason for permanently 
discontinuation on the eCRF. Once a patient has permanently discontinued protocol
therapy, the patient will not be allowed to be retreated.
8.3
Criteria for Withdrawal from Study
Patients will be withdrawn from the study if any of the following
occur:

Death

Lost to follow-up

Withdrawal of consent

The study is closed/ terminated

Investigator discretion

STATISTICAL CONSIDERATIONS
9.1
Sample Size and Study Duration
9.1.1
Review of patient accrual onto recent Phase II solid tumor studies indicates the 
following entry rates for the various tumors under study can be expected:
DiseaseGroup/Cohorts
Patients/Year
Osteosarcoma
24
Ewing sarcoma
18
Rhabdomyosarcoma
18
Neuroblastoma (measurable disease)
12
Neuroblastoma (evaluable disease)
12
Non-rhabdomyosarcomatous soft tissue sarcomas
10 
(including synovial sarcoma, alveolar soft part 
sarcoma)
Hepatoblastoma
7
With these entry rates, the probability of accruing 10 patients to complete
the initial stage of evaluation in the seven named categories within 24
months is 88%. The corresponding probability for enrolling 20 patients in the
seven named disease categories in 48 months is 95%. The study will likely
require 2 to 3.5 years for sufficient patient enrollments to evaluate pazopanib in 
the stated disease groups. A minimum of 77 patients and a maximum of 154 
patients are anticipated, after accounting for historical rates of patient 
inevaluability for the primary endpoint in phase II studies.
9.2
Study Design
The primary endpoint will be objective response by protocol-specified, disease-specific

in each of the seven disease cohorts. The following two stage design will be used in
each cohort.

We will consider the agent not of sufficient interest for further evaluation in a disease 
category if the true response rate is 5% and of sufficient activity if the true response
rate is 25%. If the agent has a true response rate of 5%, the rule described above will
identify it of sufficient activity for further study with probability 0.07 (1-sided type I
error), and the trial will have an expected sample size of 14 with 60% probability of 
early termination. If the agent has a true response rate of 25%, the rule described above
will identify it of sufficient activity for further study with probability 0.88 (power
against the alternative hypothesis P = 0.25).
9.3
Analysis Populations
The modified Intent-to-Treat (mITT) population is the primary analysis population. The 
mITT will consist of all patients who have received at least one dose of protocol therapy.
The Safety population will comprise all patients in the mITT population. The safety 
population will be used for the analysis of safety data.
The Per Protocol (PP) population is a subset of the mITT population who meet all eligibility 
criteria.
The Pharmacokinetic (PK) population will comprise all patients in the mITT population
for whom a pharmacokinetic sample is obtained and analyzed. The Pharmacokinetic 
Extended Sampling (PKES) population will comprise all subjects in the Pharmacokinetic 
population who received powder suspension and have at least one non-predose sample 
collected and analyzed using the extended sampling schedule in Section 7.3.2. PK analysis 
summaries, figures and listings will be based on PK and PKES populations.
9.4
Analysis Data Sets
The primary data set for assessing efficacy will comprise the mITT population. The PP and 
mITT populations will be used for objective response analysis. All other efficacy analyses 
will be based on mITT only.
The primary data set for assessing safety will comprise the safety population defined in
Section 9.3 (Analysis Populations).

Treatment Comparisons
There will be no treatment comparisons as there is only one treatment arm. No comparisons 
across cohorts will be conducted.
9.6
Primary Analysis and End of Study Analysis
No formal interim analysis is planned outside of the study design. The study team will review 
safety data periodically over the course of the study.
Expansion of tumor specific cohorts will be done when there is at least one investigator
determined confirmed response in that cohort within the first 10 enrolled patients. A 
given tumor specific cohort will not be expanded if all the patients in the cohort have:

Progressed

Discontinued therapy

Withdrawn consent

Been determined to be lost-to-follow-up

Or have been treated for at least 20 weeks without a response, making
it unlikely that a response will occur.
The primary analysis will be performed 20 weeks after the last patient’s first visit in the 
three cohorts of primary interest (rhabdomyosarcoma, non-rhabdomyosarcomatous soft 
tissue sarcoma and Ewing sarcoma/peripheral PNET).
The study will be completed one year from the date of the last patient’s first visit and 
the end of study analysis will be performed at the time of study completion.
Any additional data collected after the primary analysis will be included in a 
supplementary analysis and reported in a final Clinical Study Report.
9.7
Key Elements of Analysis Plan
9.7.1
Study Withdrawal
All patients who withdraw from the study will be included in analyses up to the 
time of withdrawal, regardless of the duration of treatment.
9.7.2
Missing Data
As the period of treatment for any patient will be dependent on treatment efficacy 
and toxicity, the duration of follow-up will vary between patients. Consequently,
there will be no imputation for missing data. Where appropriate, available data 
will be summarized over specified intervals (e.g. from study entry until withdrawal
from the study) using suitable summary statistics. Details will be given in the 
Reporting and Analysis Plan (RAP).
For the secondary PFS endpoint, the date associated with the last adequate disease
assessment will be used for those patients who are alive and have not progressed
at the time of analysis; such patients will be considered censored in the analysis.
9.7.3
Other Issues
Data from all participating centers will be pooled prior to analysis. It is anticipated 
that patient accrual will be spread thinly across centers and summaries of data by
center would be unlikely to be informative and will not, therefore, be provided.
Demographic and baseline characteristics will be summarized.

Two-sided 90% confidence limits will be used in the estimation of response rates 
and viewed as descriptive.
Any deviations from, or additions to, the original analysis plan described in this 
protocol will be documented in the RAP and final study report.
9.8
Methods of Analysis
9.8.1
Primary Endpoint: Objective Response Rate (ORR)
This is defined as the percentage of patients achieving either a complete or partial 
tumor response as per response criteria. The response rate will be calculated from 
the investigator review. Confirmation will be based on the disease assessment 
performed 1 cycle after the initial response. The objective response rate will be 
computed for the 3 tumor types of primary interest.
Patients in the mITT population with unknown or missing response will be treated
as non-responders (i.e., they will be included in the denominator when calculating 
the percentage).
In other words, ORR = (number of patients with a confirmed best overall response 
of CR + number of patients with a confirmed best overall response of PR) divided 
by the total number of patients in the cohort.
The assessment of activity of treatment within each histology cohort will be 
based on the decision rule outlined in Section 9.2.
90% confidence intervals will be provided to characterize the variability around 
the response rate. The data will be presented for each cohort.
9.8.2
Secondary Endpoints:
9.8.2.1
The objective response rate will be computed for the 4 tumor types of 
secondary interest. The analysis method will be the same as that described 
in Section 9.8.1.
9.8.2.2
If recruitment is stopped in the non-primary histology group(s) and it has 
less than 10 patients, the response data will display summary statistics 
and the rule in the table under Section 9.2 will not apply.
9.8.2.3
Progression-free survival (PFS) and overall survival (OS)
The analysis will evaluate the mITT population on PFS using data from 
the investigator review. PFS is defined as the interval between the date 
of first dose of protocol therapy and the earliest date of disease
progression or death due to any cause. Patients are considered to have
progressive disease if they have documented progression based on
radiologic assessment as determined by investigator review (defined in
Section 10). For patients who do not progress or die, progression-free 
survival will be censored at the date of last adequate assessment or date
of last adequate assessment prior to initiation of new anti-cancer
therapy if applicable. PFS will be summarized using a Kaplan-Meier

survival curve. The Kaplan-Meier estimate for the median progression-
free survival time and the first and third quartiles will be presented, along 
with a naive approximate 90% confidence interval if there are a sufficient
number of progressions or deaths.
Overall survival is defined as the time from the first dose of the study 
medication until death due to any cause. The OS analysis will be 
performed on the mITT population and summarized using a Kaplan-
Meier survival curve. The Kaplan-Meier estimate for the median OS 
time and the first and third quartiles will be presented, along with a naive 
approximate 90% confidence interval if there are a sufficient number of 
deaths.
Details on how event and censoring times are assigned to a patient will 
be provided in the RAP.
9.8.2.4
Duration of response (DoR)
For the subset of patients with a confirmed CR/PR, DoR is defined as the 
time from first documented evidence of complete or partial response to 
the earliest date of disease progression or death due to any cause. For 
confirmed responders who have not experienced progression or death 
prior to the date of data cut-off for analysis or starting other anticancer 
therapy, duration of response will be right-censored on the date of their 
last adequate post-baseline tumor assessment prior to the cut-off or start 
of other anticancer therapy.
Duration of response will be summarized descriptively for each cohort 
using medians and quartiles if there are 5 or more responders (confirmed 
CR/PR) in one cohort, otherwise, only a listing with subject level details 
will be provided. 
9.8.2.5
Clinical Benefit
This is defined as the percentage of patients achieving either a complete 
or partial tumor response or stable disease for at least two protocol 
scheduled disease assessments as per RECIST criteria. 90% confidence 
intervals will be produced to characterize the variability around the point 
estimate.
Time to Progression (TTP)
The analysis will evaluate the mITT population on TTP using data from 
the investigator review. TTP is defined as the interval between the date 
of first dose of protocol therapy and the earliest date of disease
progression or death due to disease under study. Patients are considered 
to have progressive disease if they have documented progression based
on radiologic assessment as determined by investigator review (defined 
in Section 10). TTP will be summarized using a Kaplan-Meier survival 
curve. The Kaplan-Meier estimate for the median time to progression 
and the first and third quartiles will be presented, along with a naive 
approximate 90% confidence interval if there are a sufficient number of 
events.
Details on how event and censoring times are assigned to a patient will

be provided in the RAP.
9.8.2.6
Safety Measures:
Safety data will be presented for all patients in the safety population 
(mITT) regardless of cohort. If there are multiple dose levels for the 
powder suspension formulation group, then data for each dose level will 
be presented in separate columns.
Clinical Laboratory Evaluations
Hematology, coagulation parameters, clinical chemistry, lipase and 
amylase, thyroid function tests, and UPC data will be summarized at 
each scheduled assessment. Hematology, coagulation parameters and 
clinical chemistry will be summarized by NCI-CTCAE version 4.0 and 
by data outside the reference range for each scheduled assessment.
Other Safety Measures
Vital signs (blood pressure, heart rate, temperature), height and weight 
will be listed for each patient and change from baseline will be included 
for blood pressure and heart rate. A descriptive summary including 
change from baseline pre-dose will also be presented. Individual profiles 
of blood pressure will be plotted by time.
The corrected QTcB interval (QTcB) will be listed for each patient and 
summarized at each scheduled assessment time. Change from baseline 
will be summarized and an analysis of central tendency (means, medians)
will be presented. A categorical analysis for each QTcB parameter will
be performed to determine the number of patients at each time point for 
the following categories:
QTcB. <450, 450 to <480, 480 to 500, and >500 msec.
QTcB change from baseline, 30 to <60 msec, and ≥60 msec.
9.9
Evaluability for Response
Response will be determined on the modified intent to treat (mITT) population consisting 
of all patients who are eligible and received at least one dose of protocol therapy.
For hepatoblastoma patients, RECIST criteria as described below will be used to provide 
an evaluation of RECIST-based response. For patients without serum alpha fetoprotein 
(AFP) elevated beyond the institutional upper limit of normal for age at the time of the start
of protocol therapy, the RECIST-based response will determine the response for the 
application of the statistical rule described in Section 9. Patients whose serum AFP level 
is elevated beyond the institutional upper level of normal for age at the start of protocol 
therapy will also be assessed for AFP-based response. Any such patient considered 
evaluable for response as described in Section 9.8 will be considered: (1) an AFP complete
responder (AFP-CR) if any serum AFP obtained on or after the start of Cycle 3 but before
the start of Cycle 7 is considered at or below the institutional upper limit of normal for 
age; or (2) an AFP partial responder (AFP-PR) if any serum AFP obtained on or after the 
start of Cycle 3 but before the start of Cycle 7 is 50% or less than that individual’s initial 
AFP but is still considered above the institutional upper level of normal age; and (3) AFP-
non-responder in any other case. The initial AFP obtained on Day 1 of protocol therapy or

the AFP obtained during enrollment (see Note in Section 3.1.7.1), if the Day 1 AFP is not 
available.
For patients evaluable for both RECIST-based and AFP-based response, the overall 
response for application of the statistical rule will be calculated as: (1) RECIST-CR or 
RECIST-PR, AFP-any response category – response; (2) RECIST-SD, AFP-CR or AFP-
PR – response; (3) Any other combination of RECIST and AFP response – non- responder.

9.11
Analysis of the Pharmacokinetic Parameters
Plasma pazopanib concentrations observed in the first 6 patients who receive pazopanib as
powder for oral suspension and are evaluable for pharmacokinetics will be analyzed with
standard non compartmental methods using WinNonlin version 5.2 or higher. Parameter
values for maximum plasma pazopanib concentration (Cmax), the time to Cmax (tmax),
and the area under the curve (AUC) from zero to the time of the last quantifiable 
concentration (AUC(0-t)) will be calculated. The AUC from zero to 24 hours after
administration (AUC (0-24)) on Day 15 will be calculated by using the predose plasma
pazopanib concentration as the concentration 24 hours after dosing. The analysis to assess
pazopanib pharmacokinetics after administration of the suspension prior to continuing 
enrollment on suspension may be performed using scheduled time. Calculations of
noncompartmental parameter values for the final analysis will be based on actual sampling
times.
Plasma pazopanib concentration values at each sampling occasion will be summarized by 
cohort as well as after combining the data from all cohorts, separately for each formulation
and each dose level, if needed. In addition, plasma pazopanib concentration values at each
sampling occasion will be summarized by age subgroups (28 days to <2 years, 2 to <12 years
of age, and 12 to 18 years of age) for each formulation and dose level, if needed. This analysis

will combine data across all disease cohorts unless pharmacokinetic differences between the 
cohorts are observed.
The pharmacokinetic parameter values in the patients with extended sampling will be 
summarized for Cycle 1 Day 1 and Cycle 1 Day 15, combining data from all patients, 
separately by dose level, if needed.
9.12
Analysis of Biological and Correlative Endpoints
The secondary analyses for examining the biologic relationship between tumor response and
angiogenic cytokines as well as the effects on toxicity (including hypertension) of 
pharmacokinetic parameters (secondary objectives 1.2.7 and 1.2.9) will be conducted 
 For the response outcome measure,
patients will be classified as responders or non-responders according to paragraphs 2 and 3
of the Primary Endpoint (Section 9.8.1) above. If response occurs in 10% or more of 
patients, the following logistic model will be fitted:

The initial analysis will be carried out with the Day 15 trough plasma concentration.
 
Toxicities, which occur in a frequency of 10% or more of toxicity evaluable courses, will 
be analyzed for association between the risk of toxicity and the particular biological 
parameter. The data will be presented as a cross tabulation of the presence of frequency 
of the toxicity of interest in toxicity-evaluable cycles
 
accounting for possible patient frailty will be fitted to the data. This analysis will not be 
segregated by disease type.
The precision attendant with these analyses will depend on the overall frequency of 
response and toxicity amongst patients enrolled on the study. The precision observed will 
be quantified by 95% confidence intervals. Adjustment for multiple testing will not be used 
for these secondary objectives.

EVALUATION CRITERIA
10.1
Common Terminology Criteria for Adverse Events (CTCAE)
This study will utilize the CTCAE of the National Cancer Institute (NCI) for toxicity
and performance reporting. The descriptions and grading scales found in the revised 
CTCAE version 4.0 will be utilized for reporting. All appropriate treatment areas should
have access to a copy of the CTCAE version 4.0, which can be downloaded from the
CTEP web site (http://ctep.cancer.gov). Additionally, toxicities are to be reported on
the appropriate case report forms.
10.2
Response Criteria
As outlined, patients will be assigned to one of the following categories for assessment of 
response: a) solid tumor and measurable disease (Section 10.3); b) neuroblastoma with 
MIBG positive lesions (Section 10.4) c) hepatoblastoma (Section 10.6)
Note: Neuroblastoma patients who do not have MIBG positive lesions should be assessed 
for response as solid tumor patients with measurable disease.
10.3
Response Criteria for Patients with Solid Tumors and Measurable Disease
Response and progression will be evaluated in this study using the revised Response 
Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1) [Eur J Ca 45:228-
247, 2009].45 Key points are that 5 target lesions are identified and that changes in the
largest diameter (unidimensional measurement) of the tumor lesions are used in
the RECIST v 1.1 criteria.
10.3.1
Measurable Disease
The presence of at least one lesion that can be accurately measured in at least 
one dimension with the longest diameter at least 10 mm (CT scan slice
thickness no greater than 5 mm). The investigator will identify up to 5
measurable lesions to be followed for response. Previously irradiated lesions
must demonstrate clear evidence of progression to be considered measurable.
Serial measurements of lesions are to be done with appropriate imaging 
modalities (e.g., CT or MRI). Bone scans cannot be used to measure lesions. The 
same method of assessment is to be used to characterize each identified and 
reported lesion at baseline and during follow-up.
10.3.2
Quantification of Disease Burden
The sum of the longest diameter (LD) for all target lesions will be calculated 
and reported as the disease measurement.
10.3.3
End-of-Cycle Response
Note: Please also see Table 1 in Section 10.7.
a.
Complete Response (CR)
Disappearance of all target and non-target lesions. Normalization of
urinary catecholamines (for patients with neuroblastoma), immunocytologic 
findings, or other tumor markers if abnormal or elevated at study enrollment.

Novartis
Confidential
Page 82
Amended Protocol Version 05 Clean
Protocol No. VEG116731
b.
Partial Response (PR)
At least a 30% decrease in the disease measurement, taking as reference
the disease measurement done to confirm measurable disease at study
enrollment. No new lesions or progression of any non-target measurable 
lesion.
c.
Stable Disease
Neither sufficient shrinkage to qualify for PR nor sufficient increase to 
qualify for PD taking as reference the smallest disease measurement since
the treatment started.
d.
Progressive Disease (PD)
At least a 20% increase in the sum of the disease measurements for 
measurable
lesions,
taking
as
reference
the
smallest
disease
measurement recorded since the start of treatment, or the appearance of
one or more new lesions.
10.3.4 Overall Best Assessment Response
Each patient will be classified according to their “best response” for the purposes 
of analysis of treatment effect. Best response is determined from the sequence
of the objective statuses described in Table 1 and 2 in Section 10.7.
10.4
Response Criteria for Neuroblastoma Patients with 123I-MIBG Positive Lesions
10.4.1
MIBG Positive Lesions
Patients who have a positive MIBG scan at the start of therapy will be evaluable 
for MIBG response. The use of 123I for MIBG imaging is recommended for all 
scans. If the patient has only one MIBG positive lesion and that lesion was 
irradiated, a biopsy must be done at least 4 weeks after radiation was completed 
and must show viable neuroblastoma.
10.4.2 The following criteria will be used to report MIBG response by the treating 
institution:

Complete Response: Complete resolution of all MIBG positive 
lesions

Partial Response: Resolution of at least one MIBG positive
lesion, with persistence of other MIBG positive lesions.

Stable Disease: No change in MIBG scan in number of
positive lesions (includes patients who have same number of
positive lesions but decreased density).

Progressive Disease: Development of new MIBG positive lesions.
10.4.3 The response of MIBG lesions will be assessed using the Curie scale as outlined 
below.
The body is divided into 9 anatomic sectors for osteomedullary lesions, with
a 10th general sector allocated for any extra-osseous lesion visible on MIBG
scan. In each region, the lesions are scored as follows. The absolute extension 
score is graded as:
0 = no site per segment,
1 = 1 site per segment,
2 = more than one site per segment,

Novartis
Confidential
Page 83
Amended Protocol Version 05 Clean
Protocol No. VEG116731
3 = massive involvement (>50% of the segment).
The absolute score is obtained by adding the score of all the segments.
See diagram of sectors below:
The relative score is calculated by dividing the absolute score at each time point 
by the corresponding pre-treatment absolute score. The relative score of each 
patient is calculated at each response assessment compared to baseline and 
classified as below:
1. Complete response: all areas of uptake on MIBG scan completely resolved.
If morphological evidence of tumor cells in bone marrow biopsy or aspiration is
present at enrollment, the patient will be determined to have a
complete response when no tumor cells can be detected by routine morphology
on two subsequent bilateral bone marrow aspirates and biopsies which are done at
least 3 weeks apart.
2. Partial response: Relative score ≤0.2 (lesions almost disappeared) to ≤0.5
(lesions strongly reduced).
3. Stable disease: Relative score > 0.5 (lesions weakly but significantly reduced) 
to 1.0 (lesions not reduced).
4. Progressive disease: New lesions on MIBG scan
10.4.4
Overall Best Response Assessment
Each patient will be classified according to their “best response” for the 
purposes of analysis of treatment effect. Best response is determined from the
sequence of the objective statutes described in Table 3 in Section 10.7.
10.5
Response Criteria for the Bone Marrow in Neuroblastoma Patients
10.5.1
Bone Marrow Response
Bone Marrow response is determined by H&E staining of bilateral bone marrow 
biopsies and aspirates.

Complete Response: No tumor cells detectable by routine morphology
on 2 consecutive bilateral bone marrow aspirates and biopsies performed at 
least 3 weeks apart.

ProgressiveDisease:

Novartis
Confidential
Page 84
Amended Protocol Version 05 Clean
Protocol No. VEG116731
o
Patients who enroll with neuroblastoma in the bone marrow by 
morphology have progressive disease if there is a doubling in the 
amount of tumor in the marrow AND have a minimum of 25% tumor 
in the bone marrow by morphology. (For example, a patient entering
with 5% tumor in the bone marrow by morphology must increase to
≥25% tumor to have progressive disease; a patient entering with 30% 
tumor must increase to > 60%).
o
Patients who enroll without evidence of neuroblastoma in the bone 
marrow will be defined as progressive disease if tumor is detected
in 2 consecutive bone marrow biopsies or aspirations done at least 3 
weeks apart.

StableDisease: Persistence of tumor in bone marrow that does not meet
the criteria for either complete response or progressive disease.
10.5.2
The above Bone marrow response criteria will be utilized for Neuroblastoma
patients when determining the Overall Best Response in Section 10.7.
10.6
Response Criteria for Hepatoblastoma
10.6.1
For hepatoblastoma patients, RECIST criteria as described above will be used
to provide an evaluation of RECIST-based response. For patients without serum 
alpha fetoprotein (AFP) elevated beyond the institutional upper limit of
normal for age at the time of the start of protocol therapy, the RECIST-based
response will determine the response for the application of the statistical rule
described in Section 9. Patients whose serum AFP elevated beyond the
institutional upper level of normal at the start of protocol therapy will also be 
assessed for AFP- based response. Any such patient considered evaluable for
response as described in Section 9.4 above will be considered: (1) an AFP
complete responder (AFP- CR) if any serum AFP obtained on or after the
start of Cycle 3 but before the start of Cycle 7 is considered at or below the
institutional upper limit of normal for age; or (2) an AFP partial responder
(AFP-PR) if any serum AFP obtained on or after the start of Cycle 3 but before 
the start of Cycle 7 is 50% or less than that individual’s initial AFP but is still
considered above the institutional upper level of normal for age; and (3) AFP-
non-responder in any other case. The initial AFP is the AFP obtained on Day
1 of protocol therapy or the AFP obtained during enrollment, if the Day 1 
AFP is not available.
For patients evaluable for both RECIST-based and AFP-based response, the 
overall response for application of the statistical rule will be calculated as: (1)
RECIST-CR or RECIST-PR, AFP-any response category – response; (2) 
RECIST-SD, AFP-CR or AFP-PR – Response; (3) Any other combination of 
RECIST and AFP response – non-responder.
10.6.2
Measurement of serum AFP markers
The serum AFP should be collected immediately prior to starting therapy on
the first day of treatment, and again at each scheduled disease evaluation if the 
initial value is elevated. The value must be reported as a precise number, and
not as an estimate (e.g., > 50,000 ng/mL). This may require serial dilutions of
samples in order to obtain an accurate value. In addition, values that are
unexpectedly low should also be confirmed by serial dilutions.

10.6.3
Overall Response Assessment
The overall response assessment for hepatoblastoma patients takes into account 
response in the measurable and non-measurable disease, and the appearance
of new lesions, where applicable, and decline of AFP according to the criteria 
described in Table 4 below.
10.7
Best Response (Solid Tumors)
Two objective status determinations of disease status, by CT or MRI, obtained on two 
consecutive determinations, separated by at least a 3 week time period, are required
to determine the patient’s overall best response. Two objective status determinations of
CR before progression are required for best response of CR. Two determinations of PR
or better before progression, but not qualifying for a CR, are required for a best response 
of PR. Two determinations of stable/no response or better before progression, but not 
qualifying as CR or PR, are required for a best response of stable/no response; if the first 
objective status is unknown, only one such determination is required. Patients with
an objective status of progression on or before the second evaluations (the first
evaluation is the first radiographic evaluation after treatment has been administered) 
will have a best response of progressive disease. Best response is unknown if the patient
does not qualify for a best response of progressive disease and if all objective statuses
after the first determination and before progression are unknown.

Survival Follow-Up
Patients who have discontinued protocol therapy will be followed for Survival status. The 
investigator site will collect and report Survival follow-up in the eCRF every 3 months,
which would include the patient’s survival status and any antineoplastic therapies taken
since discontinuation of protocol therapy, until death, lost to follow-up, or withdrawal of
consent from survival follow-up occurs or final cut-off for survival analysis.
The date and cause of death should be recorded in the eCRF.

ADVERSE EVENT (AE) AND SERIOUS ADVERSE EVENTS (SAE)
The investigator or site staff is responsible for detecting, documenting and reporting events
that meet the definition of an AE or SAE.

AEs will be collected from the start of protocol therapy and until 28 days following last 
dose of protocol therapy.
SAEs will be collected over the same time period as stated above for AEs. From the time 
a patient consents to participate in and completes the study, all SAEs assessed as related 
to study participation (e.g., study treatment, protocol-mandated procedures, invasive tests, or 
change in existing therapy)  will be reported promptly to Novartis as indicated in Section 
11.8.
Medical occurrences that begin prior to the start of protocol therapy but after obtaining 
informed consent should be recorded on the Medical History/Current Medical Conditions 
section of the eCRF.
Any new primary cancer must be recorded as an SAE and will be recorded from the time a
patient consents to participate in the study up to and including any follow-up contact.
All SAEs will be recorded and reported to Novartis and COG within 24 hours, as indicated 
in Section 11.8.
Investigators are not obligated to actively seek AEs or SAEs in former study participants.
However, if the investigator learns of any SAE, including a death, at any time after a patient
has been discharged from the study, and he/she considers the event reasonably related to the
study treatment or study participation, the investigator should promptly notify Novartis and
COG.
11.1
Definition of Adverse Events (AEs)
An AE is any untoward medical occurrence in a patient or clinical investigation patient, 
temporally associated with the use of a medicinal product, whether or not considered related
to the medicinal product. CTCAE criteria version 4.0 will be used to grade severity 
of adverse events.
Note: An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated with 
the use of a medicinal product
Events meeting the definition of an AE include:

Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis)
or
other
safety
assessments
(e.g.,
ECGs,
radiological scans, vital signs 
measurements), including those that worsen from baseline, and felt to be clinically 
significant in the medical and scientific judgment of the investigator

Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition.

New conditions detected or diagnosed after study treatment administration even 
though it may have been present prior to the start of the study.

Signs, symptoms, or the clinical sequelae of a suspected interaction.

Signs, symptoms, or the clinical sequelae of a suspected overdose of either study 
treatment or a concomitant medication. (Overdose per se will not be reported as an
AE/SAE unless it is an intentional overdose taken with possible suicidal/self-
harming intent. This should be reported regardless of sequelae.)

"Lack of efficacy" or "failure of expected pharmacological action" per se will not be
reported as an AE or SAE. However, the signs and symptoms and/or clinical sequelae 
resulting from lack of efficacy will be reported if they fulfil the definition of an AE 
or SAE.

Novartis
Confidential
Page 89
Amended Protocol Version 05 Clean
Protocol No. VEG116731
Events that do not meet the definition of an AE include:

Any clinically significant abnormal laboratory findings or other abnormal safety 
assessments that are associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the patient’s condition.

The disease/disorder being studied, or expected progression, signs, or symptoms of
the disease/disorder being studied, unless more severe than expected for the patient’s 
condition.

Medical or surgical procedure (e.g., endoscopy, appendectomy); the condition 
that leads to the procedure is an AE.

Situations where an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital).

Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen.
11.2
Definition of Serious Adverse Events (SAEs)
Refer to Section 11.8 for reporting requirements including the within 24 hour time limit 
for all SAEs as defined below.
If an event is not an AE per Section 11.1 then it cannot be an SAE even if serious conditions
are met (e.g., hospitalization for signs/symptoms of the disease under study, death due to 
progression of disease, etc).
An SAE is any untoward medical occurrence that, at any dose:

Results in death

Is life-threatening
NOTE: The term 'life-threatening' in the definition of 'serious' refers to an event in 
which the patient was at risk of death at the time of the event. It does not refer to an
event, which hypothetically might have caused death, if it were more severe.

Requires hospitalization or prolongation of existing hospitalization
NOTE: In general, hospitalization signifies that the patient has been detained 
(usually involving at least an overnight stay) at the hospital or emergency department 
for observation and/or treatment that would not have been appropriate in the
physician’s office or out-patient
setting. Complications that occur
during
hospitalization are AEs. If a complication prolongs hospitalization or fulfills any
other serious criteria, the event is serious. When in doubt as to whether 
“hospitalization” occurred or was necessary, the AE should be considered serious.
Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE.

Results in disability/incapacity
NOTE: The term disability means a substantial disruption of a person’s ability to 
conduct normal life functions. This definition is not intended to include experiences 
of relatively minor medical significance such as uncomplicated headache, nausea, 
vomiting, diarrhea, influenza, or accidental trauma (e.g.sprained ankle) which may 
interfere or prevent everyday life functions but do not constitute a substantial 
disruption.

Is a congenital anomaly/birth defect

Medical or scientific judgment should be exercised in deciding whether 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

Novartis
Confidential
Page 90
Amended Protocol Version 05 Clean
Protocol No. VEG116731
the patient or may require medical or surgical intervention to prevent one of the other
outcomes listed in the above definition. These should also be considered serious.
Examples of such events are invasive or malignant cancers, intensive treatment in an
emergency room or at home for allergic bronchospasm, blood dyscrasias or
convulsions that do not result in hospitalization, or development of drug dependency 
or drug abuse.

All events of possible drug-induced liver injury with hyperbilirubinaemia defined as 
ALT > 3xULN and bilirubin > 1.5x ULN (>35% of total bilirubin is direct) or ALT
> 3xULN and INR>1.5, if INR measured termed ‘Hy’s Law’ events (INR 
measurement is not required and the threshold value stated will not apply to patients 
receiving anticoagulants).
NOTE: Bilirubin fractionation is performed if testing is available. If testing is 
unavailable, record presence of detectable urinary bilirubin on dipstick indicating 
direct bilirubin elevations and suggesting liver injury. If testing is unavailable 
and a patient meets the criterion of total bilirubin 2xULN, then the event is still 
reported as an SAE. If INR is obtained, include values on the SAE form. INR 
elevations >1.5 suggest severe liver injury.
11.3
Method of Detecting AEs and SAEs
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended 
and non-leading verbal questioning of the patient is the preferred method to inquire about 
AE occurrence. Appropriate questions include:

“How are you feeling?” or “How does your child seem to feel?”

“Have you had any (other) medical problems since your last visit/contact?” or

“Has your child had any (other) medical problems or seem to act differently in 
any way since his/her last visit/contact?”

“Have you taken any new medicines, other than those provided in this study, 
since your last visit/contact?” or “Has your child needed to take any medicines,
other than those provided in this study, since his/her last visit/contact?”
11.4
Disease-Related Events and/or Disease-Related Outcomes Not Qualifying as SAEs
An event which is part of the natural course of the disease under study (i.e., disease 
progression or hospitalization due to disease progression) does not need to be reported as an
SAE. Death due to disease under study is to be recorded on the Death eCRF form. However,
if the underlying disease (i.e., progression) is greater than that which would normally be
expected for the patient, or if the investigator considers that there was a causal 
relationship between treatment with study medication(s) or protocol design/procedures and 
the disease progression, then this must be reported as an SAE.
11.5
Recording of AEs and SAEs
When an AE/SAE occurs, it is the responsibility of the investigator to review all 
documentation (e.g., hospital progress notes, laboratory, and diagnostics reports) relative to
the event. The investigator will then record all relevant information regarding an AE/SAE in 
the appropriate data collection tool.
It is not acceptable for the investigator to send photocopies of the patient’s medical 
records to Novartis or COG in lieu of completion of the Novartis AE/SAE data collection
tool. However, there may be instances when copies of medical records for certain cases are 

Novartis
Confidential
Page 91
Amended Protocol Version 05 Clean
Protocol No. VEG116731
requested by Novartis and COG. In this instance, all patient identifiers, with the exception
of the patient number (both COG and Novartis study numbers), will be blinded on the copies 
of the medical records prior to submission to Novartis.
The investigator will attempt to establish a diagnosis of the event based on signs, symptoms,
and/or other clinical information. In such cases, the diagnosis will be documented as the 
AE/SAE and not the individual signs/symptoms.
11.6
Evaluating AEs and SAEs
11.6.1
Assessment of Intensity
The investigator will make an assessment of intensity for each AE and SAE
reported during the study and will assign it to one of the following categories:
Mild: An event that is easily tolerated by the patient, causing minimal discomfort 
and not interfering with everyday activities.
Moderate: An event that is sufficiently discomforting to interfere with normal 
everyday activities.
Severe: An event that prevents normal everyday activities
An AE that is assessed as severe will not be confused with an SAE. Severity is a 
category utilized for rating the intensity of an event, and both AEs and SAEs can 
be assessed as severe. An event is defined as ‘serious’ when it meets at least one 
of the pre-defined outcomes as described in the definition of an SAE.
11.6.2
Assessment of Causality
The investigator is obligated to assess the relationship between study treatment and
the occurrence of each AE/SAE. A "reasonable possibility" is meant to convey that 
there are facts/evidence or arguments to suggest a causal relationship, rather than a
relationship cannot be ruled out. The investigator will use clinical judgment to
determine the relationship. Alternative causes, such as natural history of the 
underlying diseases, concomitant therapy, other risk factors, and the temporal
relationship of the event to the study treatment will be considered and investigated.
The investigator will also consult the Investigator Brochure (IB) and/or Product
Information, for marketed products, in the determination of his/her assessment.
For each AE/SAE the investigator must document in the medical notes that 
he/she has reviewed the AE/SAE and has provided an assessment of causality.
11.7
Follow-up of AEs and SAEs
After the initial AE/SAE report, the investigator is required to proactively follow each 
patient at subsequent visits/contacts. All AEs and SAEs will be followed until resolution, 
until the condition stabilizes, until the event is otherwise explained, or until the patient is lost 
to follow-up.
The investigator is obligated to perform or arrange for the conduct of supplemental 
measurements and/or evaluations as may be indicated or as requested by Novartis to elucidate
as fully as possible the nature and/or causality of the AE or SAE. The investigator is obligated 
to assist. This may include additional laboratory tests or investigations, histopathological 
examinations or consultation with other health care professionals. If a patient dies during
participation in the study or during a recognized follow-up period, the investigator will 

Novartis
Confidential
Page 92
Amended Protocol Version 05 Clean
Protocol No. VEG116731
provide Novartis with a copy of any post-mortem findings, including histopathology.
New or updated information will be recorded in the originally completed data collection tool.
The investigator will submit any updated SAE data to Novartis within the designated 
reporting time frames
11.8
Prompt Reporting of SAEs to Novartis and COG
Once the investigator determines that an event meets the protocol definition of an SAE, 
the SAE will be reported to Novartis and COG within 24 hours. Any follow-up information 
on a previously reported SAE will also be reported to Novartis and COG within 24 hours. If 
the investigator does not have all information regarding an SAE, he/she will not wait to 
receive additional information before notifying Novartis and COG of the event and 
completing the appropriate data collection tool. The investigator will always provide an 
assessment of causality at the time of the initial report as described in Section 11.6.2, 
Assessment of Causality.
The primary mechanism for reporting SAEs to Novartis and COG will be the electronic data 
collection tool. If the electronic system is unavailable for greater than 24 hours, the site will 
use the paper SAE data collection tool and fax it to the number included in the Study 
Procedures Manual. Then the site will enter the SAE data into the electronic system as soon 
as it becomes available.
After the study is completed at a given site, the electronic data collection tool (e.g., 
DataLabs™system) will be taken off-line to prevent the entry of new data or changes to 
existing data. If a site receives a report of a new SAE from a study participant or receives 
updated data on a previously reported SAE after the electronic data collection tool has been
taken off-line, the site can report this information on a paper SAE form or to their Novartis
protocol contact by telephone.
Novartis contacts for SAE receipt can be found at the beginning of this protocol on the
Sponsor Information page.
11.9
Regulatory Reporting Requirements for SAEs
Prompt notification of SAEs by the investigator to Novartis is essential so that legal 
obligations and ethical responsibilities towards the safety of patients are met. Novartis has a 
legal responsibility to notify both the local regulatory authority and other regulatory 
agencies about the safety of a product under clinical investigation. Novartis will comply with 
country specific regulatory requirements relating to safety reporting to regulatory authorities, 
IRBs/Independent Ethics Committees (IECs) and investigators.
Investigator safety reports are prepared for suspected unexpected serious adverse 
reactions according to local regulatory requirements and Novartis policy and are 
forwarded to investigators as necessary. An investigator who receives an investigator
safety report describing an SAE(s) or other specific safety information (e.g., summary
or listing of SAEs) from Novartis will file it with the IB and will notify the IRB/IEC, 
if appropriate according to local requirements.

STUDY REPORTING AND MONITORING
For this study, patient data will be entered into electronic case report forms (eCRFs), transmitted 
electronically to Novartis or designee and be combined with data provided from other sources
in a validated data system.
Clinical data management will be performed in accordance with applicable standards and data 
cleaning procedures with the objective of resolving errors and inconsistencies in the data which 
would otherwise impact on the analysis and reporting objectives, or the credibility of the Clinical 
Study Report. All AEs and concomitant medications terms will be coded using the Medical 
Dictionary for Regulatory Activities (MedDRA) and a custom dictionary. eCRFs (including
queries and audit trails) will be retained by Novartis, and copies will be sent to the investigator 
to maintain as the investigator copy.
12.1
Data and Safety Monitoring
A formal data safety monitoring board will not be utilized for this open-label study. The 
following procedures will be followed to provide appropriate data and safety monitoring for
this study:

The study team, which includes the Medical Lead, representatives from the Clinical 
Pharmacology Group, and the COG protocol chair will review and discuss safety data
at periodic intervals throughout the duration of the study.

APPENDIX IV: URINE PROTEIN TO CREATININE (UPC) RATIO
Clinical Meaning of UPC
There is a good correlation between the ratio of urine protein to urine creatinine concentrations (UPC) in 
a random urine sample and the amount of protein excreted in a 24-hour urine collection period. 48 Thus, 
the UPC ratio from a single random urine sample permits estimation of the 24-hour urine protein excretion.
The creatinine excretion is fairly constant throughout the day regardless of changes in urine flow rate:

Men excrete 20 mg to 25 mg of creatinine/kg of body weight/day

Women excrete 15 mg to 20 mg of creatinine/kg of body weight/day

Normal protein excretion is <100 mg to 150 mg per 24 hours.

The UPC ratio is roughly equal to the 24-hour urine protein excretion in g/day
Calculating UPC Ratio
UPC ratio = (Urine protein [mg/dL]) / (urine creatinine [mg/dL]) = numerically equivalent to grams (g)
protein excreted in urine over 24 hours.
Example: If a patient has a urine protein concentration of 90 mg/dL and urine creatinine concentration of
30 mg/dL,
then UPC ratio =
90(mg/dL) = 3
30 (mg/dL)
UPC ratio of 3 correlates to roughly 3g of protein excretion in a 24-hour period.
Units for UPC ratio
UPC is a calculated ratio. The guidelines in the protocol are based on having urine protein and urine
creatinine measured in the same units (e.g., mg/dL). The International System of Units (SI) units for urine 
protein and urine creatinine are not the same, so these must be converted to mg/dL before calculating the 
ratio. For reference, the conversion factors for commonly used units for protein and creatinine are provided 
below.
Starting units
Conversion to mg/dL

Sample Collection, Handling, and Processing
1.
Blood samples will be collected into tubes containing potassium EDTA as an anticoagulant and 
may be drawn from a central venous catheter.
2.
The samples should be centrifuged at approximately 2500 x g at 5oC for 10 minutes. The resulting 
volume of plasma will be transferred in equal aliquots to two (2) corresponding pre-labeled 
polypropylene storage tubes. The tubes will be frozen in an upright position at -20oC until shipped 
to the laboratory for analysis.
3.
Each tube must be labeled with the Sponsor study specific patient number, the study I.D. 
(ADVL1322/VEG116731), and the date and time the sample was drawn. Please also see the 
instructions in the 
 Central Laboratory Services Manual (binder) that is provided with the 
initial start up PK kits from

This document provides instructions for patients/caregivers on the administration and storage of pazopanib 
suspension. It also details how to clean up in the event of a spill. Any leftover medication should be 
returned to your doctor. You should read the information on these pages before you give your child the 
suspension. Please read these instructions carefully and ask your doctor about any questions you 
may have.
A. Administration:
1.
The pharmacist should insert the provided adapter (Baxa 28 mm Press-In-Bottle Adapter - PIBA®)
into the neck of the bottle. Once the adapter has been placed into the bottle neck, DO NOT 
REMOVE.
2.
Immediately before planned dose administration, mix the contents of the bottle by swirling for 30 
seconds to one minute in order to ensure homogeneity of suspension.
3.
Note#1: Women who are pregnant or nursing should put on a suitable size of gloves to avoid 
contact between the liquid and skin (Latex gloves can be used; however, for people who are 
sensitive to latex, it is recommended to use Nitrile gloves). Take care not to spread material to 
unprotected skin (such as your face) or other body surfaces by touching them with a wet glove. 
Note#2: In case of spillage, see section C for Clean-up instructions.
3.
Insert the tip of an appropriate syringe (recommended: Exacta-Med® Baxa) into the Adapter after 
ensuring that the syringe plunger is pushed fully into the barrel.
4.
Tip the bottle upside down and dispense at least 3-5 mL of suspension into the syringe. Then push 
the suspension back into the bottle in order to purge the syringe of any air bubbles. Repeat this 
step until syringe is free of air bubbles.
5.
Withdraw the prescribed dose. Investigator/study staff will fill in the dose below for each patient.
The dose is 
mg, corresponding to 
mL each day.
Please note that the number of milligrams of pazopanib and, therefore, the number of milliliters of 
pazopanib oral suspension may change as the body surface area of the patient changes during study 
participation.
6.
After you have given your child the dose, pull the plungers out of all the syringes and rinse the 
syringes and plungers with warm water for 30 seconds. When dry, place the plungers back into 
their syringes and store them for the next time.
7.
Pazopanib is to be given orally (by mouth) only.
8.
The dose should be given on an empty stomach (1 hour before or 2 hours after a meal) once daily.
9.
If your child’s study doctor prescribed medicine to prevent nausea or vomiting with pazopanib, 
you should give your child this medicine 30-60 minutes before you give pazopanib.
10. If your child spits out or vomits a dose of pazopanib, it should not be repeated.
11. If a dose is missed, it may be given within 12 hours of the time it was due. Beyond 12 hours that 
dose should be skipped. The next dose should be given at its regularly scheduled time. For
example, if the dose was due at 8am, then the dose may be given up to 8pm that same day.
B. Storage and returning partially used and unused bottles:
1.
The pazopanib suspension should be refrigerated in its bottle (2° to 8°C, or 36° to 46°F).
2.
Pazopanib must be kept out of reach of children.
3.
Any used and unused bottles of pazopanib should be returned to the investigator/clinic at each 
study visit.

C. Clean-up Instructions in case of spillage:
Note: Women who are pregnant or nursing should avoid doing the clean-up because there is a risk 
of possible harm in developing human offspring or nursing infants.
4. Put on a suitable size of gloves. Latex gloves can be used; however, for people who are sensitive to 
latex, it is recommended to use Nitrile gloves.
Note: Use gloves for the clean-up process to avoid contact between the liquid spill and skin.
Take care not to spread spilled material to unprotected skin (such as your face) or other body 
surfaces by touching them with a wet glove.
5. Add enough absorbent material (eg: kitty litter, coffee grounds, or paper towels) onto the spilled
material to soak it up.
6. Place the soaked absorbent material into a sealable plastic bag, and then seal the bag.
7. Wipe the spilled area with an alcohol moistened towel (paper or cloth) and allow area to dry.
12.Place the sealed bag, towels, gloves into a second sealable bag then put into the household trash.

INFORMATION SHEET REGARDING RESEARCH STUDY ADVL1322 
(for children from 7 through 12 years of age)
A study of pazopanib in children with cancer that has come back after 
treatment or is difficult to treat
1. We have been talking with you about your cancer. You have had treatment for the cancer already but 
the cancer did not go away or it came back after treatment.
2. We are asking you to take part in a research study because other treatments did not get rid of the 
cancer. A research study is when doctors work together to try out new ways to help people who 
are sick. In this study, we are trying to learn more about how to treat the kind of cancer that you have. 
We will do this by trying a new medicine to treat your cancer.
3. Children who are part of this study will be treated with a cancer-fighting medicine called pazopanib. 
You will also have regular tests and exams done more often while you are in this study. The doctors
want to see if pazopanib will make more children with your type of cancer get better. We don’t
know if pazopanib will work well to get rid of your cancer. That is why we are doing this study.
4. Sometimes good things can happen to people when they are in a research study. These good things are
called “benefits.” We hope that a benefit to you of being part of this study is that pazopanib may
cause your cancer to stop growing or to shrink for a period of time. However, we don’t know for 
sure if there is any benefit of being part of this study.
5. Sometimes bad things can happen to people when they are in a research study. These bad things are
called “risks.” The risks to you from this study are that you may have more problems, or side effects,
from pazopanib than other treatments. Other things may happen to you that we don’t yet know about.
6. Your family can choose to be part of this study or not. Your family can also decide to stop being in 
this study at any time once you start. There may be other treatments for your illness that your 
doctor can tell you about. Make sure to ask your doctors any questions that you have.
7. We are asking your permission to collect additional blood. We want to learn more about how 
pazopanib works. Sample would be taken before you start treatment and 2 weeks after you start 
treatment. The extra blood would be taken only at times when blood is collected for regular treatment
tests, so there would be no extra needle sticks. You can still take part in this study even if you don't 
allow us to collect the extra blood samples for research.

INFORMATION SHEET REGARDING RESEARCH STUDY ADVL1322 
(for teens from 13 through 17 years of age)
A study of pazopanib in children with cancer that has come back after 
treatment or is difficult to treat
1. We have been talking with you about your cancer. You have had treatment for the cancer already but 
the cancer did not go away or it came back after treatment.
2. We are asking you to take part in a research study because other treatments did not get rid of the 
cancer. A research study is when doctors work together to try out new ways to help people who 
are sick. In this study, we are trying to learn more about how to treat the kind of cancer that you have.
3. Children and teens who are part of this study will be given a cancer-fighting medicine called pazopanib.
Pazopanib is a drug that in laboratory studies can block proteins which are thought to be important
for tumors to grow. You will get pazopanib once a day (by mouth) for 28 days. This 28 day regimen
may be repeated until you benefit from treatment or until study closure. You will get the pazopanib
as long as you do not have bad effects from it and your cancer does not get any worse. You will also 
have exams and tests done that are part of normal cancer care. But, the exams and tests will be done
more often while you are being treated with pazopanib. The doctors want to see if pazopanib will
make more children with your type of cancer get better. We don’t know if pazopanib is better than 
other medicines. That is why we are doing this study.
4. Sometimes good things can happen to people when they are in a research study. These good things are
called “benefits.” We hope that a benefit to you of being part of this study is that pazopanib may 
cause your cancer to stop growing or to shrink for a period of time. However we don’t know for sure 
if there is any benefit of being part of this study.
5. Sometimes bad things can happen to people when they are in a research study. These bad things are 
called “risks.” The risks to you from this study may be a less effective treatment and more side effects
than other treatments for your cancer. Other things may happen to you that we don’t yet know about.
6. Your family can choose to be part of this study or not. Your family can also decide to stop being in 
this study at any time once you start. There may be other treatments for your illness that your 
doctor can tell you about. Make sure to ask your doctors any questions that you have.
7. We are asking your permission to collect additional blood. It will be helpful for us to see how your 
body handles the pazopanib and how pazopanib works. Sample would be taken before you start 
treatment and 2 weeks after you start treatment. The extra blood would be taken only at times 
when blood is collected for regular treatment tests, so there would be no extra needle sticks. You can
still take part in this study even if you don't allow us to collect the extra blood samples for research.

Summary of Amendment Changes with Rationale
List of Specific Changes
Change
Rationale
The requirement to dose patients with tablets was changed
from a BSA of 0.48 to 0.84 based on the available tablet 
strengths.
The starting dose for suspension was changed from 160 
mg/m2 to 225 mg/m2
The pazopanib Phase I trial (ADVL0815) established 
different Maximum Tolerated Doses for the PfOS 
(160mg/m2) and tablet formulation (450mg/m2).
The available tablet strengths will allow for dosing of 
children/adolescents to have a BSA of 0.84 mg/m2.
The mg/m2 starting dose will be 225 mg/m2 which is 
greater than the MTD (160 mg/m2) established in the 
Phase I study (ADVL0815) where 2 isolated reversible 
laboratory DLTs where observed. The initial 6 patients 
who require suspension will have extended PK sampling 
and safety monitoring for DLTs. If the 225 mg/m2 dose 
is not tolerated subsequent patients who require 
suspension will receive 160 mg/m2/dose.
Clarification around continuation of therapy following
toxicity incorporated.
To provide investigators clarification and guidance 
around dose interruptions and modifications required 
when toxicity observed.
Monitoring of Pregnancy incorporated
Monitoring and documentation of pregnancy required for 
those females and partners of male subjects that become 
pregnant while participating in this study.
Protocol specific SAEs that were associated with another
asset were removed.
Protocol specific SAEs were incorrectly included in the 
protocol and are not appropriate to be included in this 
study.
General administrative changes including updating TOC,
formatting and Appendix references changed throughout 
the protocol.

Experimental Design Schema Previous Text:
Pazopanib will be administered orally once daily as a tablet at a dose of 450 mg/m2/dose or as a powder in 
suspension at a dose of 160 mg/m2/dose (the MTDs determined by Part 1 and Part 2A respectively of 
ADVL0815, the COG Phase I study). The maximum dose to be administered daily is 800 mg. Each cycle will
be defined as 28 days. Note: The first 10 patients enrolled will receive the suspension formulation during Cycle 
1 in order to obtain pharmacokinetic data. Those patients may switch to the tablet formulation for Cycle 2 and
subsequent cycles if the patient is able to swallow tablets and meets the minimum BSA requirements for
tablets. Please note, the prescribed dose for the tablet and suspension formulation is different (see Section 
4.1).
Patients with benefit (stable disease or an objective response) may continue therapy for up to 2 years (in the
absence of unacceptable treatment related toxicity) unless there is evidence of progressive disease or 
unacceptable treatment-related toxicity.
Experimental Design Schema Revised Text:
Pazopanib will be administered orally once daily as a tablet at 450 mg/m2/dose or as a powder in suspension
at 225 mg/m2/dose. The maximum tolerated dose (MTD) for tablets was 450 mg/m2/dose as determined by
ADVL0815, the COG Phase I study, while the dose for oral suspension of 225 mg/m2/dose exceeds the
protocol-specified MTD of 160 mg/m2/dose established in that study. The 225 mg/m2/dose is where two 
isolated laboratory-defined dose-limiting toxicities (DLTs) were observed. The maximum dose to be 
administered daily for tablets is 800 mg. The maximum dose to be administered daily for suspension is 400 
mg. Each cycle will be defined as 28 days.
The first 6 patients enrolled who receive suspension will be expected to complete extended pharmacokinetic
(PK) sampling (Section 7.3.2) in order to obtain PK and safety data. These data will be reviewed prior to
further enrollment of patients requiring suspension to determine if 225 mg/m2/dose is tolerated and PK
exposure is similar to exposure in adults associated with clinical efficacy. If the 225 mg/m2/dose is not
tolerated (≥2 dose limiting toxicities (DLTs) in 6 evaluable patients), the dose for patients who require 
suspension may be reduced to 160 mg/m2/dose.

existing cardiac disease. When using pazopanib, baseline and periodic monitoring of ECGs and maintenance 
of electrolytes (calcium, magnesium, potassium) within normal range is recommended.
Section 2.3.3 Efficacy Data in Adults with Cancer, Previous Text (Paragraphs 4 and 5):
In two separate Phase II studies
of renal cell and NSCLC presented at the 2008 annual meeting of the American Society for Clinical
Oncology (ASCO) a decrease in sVEGFR2 compared with baseline was significantly correlated with tumor
response (p < 0.05).37,38 In adult patients with metastatic imatinib-refractory gastrointestinal stromal tumors
treated with sunitinib, another VEGF and c-kit targeting multityrosine kinase inhibitor, biomarker analysis of 
CECs, monocytes, VEGF, and sVEGFR-2 were consistently modulated by treatment. In this study, changes in 
CECs and monocytes rather than plasma markers differed between the patients with clinical benefit and those
with progressive disease.39 In pediatric patients with refractory solid tumors treated with the VEGF
neutralizing antibody bevacizumab, patients with prolonged disease stabilization (> 3 months) had a greater 
contribution of apoptotic CEC to the total CEC number (aCEC/tCEC) after 4 weeks of therapy (p=0.04), a
finding also reported in breast cancer patients who responded to metronomic therapy.40,41 This study will
continue to examine the effects of pazopanib therapy on cytokines and angiogenic factors.
3)The GlaxoSmithKline genetics team led by Dr.
has recently published results of a candidate gene 
association study in adult RCC patients treated with pazopanib.25 Several polymorphisms in candidate 
genes demonstrated associations with response rate and progression-free survival. Validation and 
elaboration of these findings will become available prior to completion of this trial. Based on the adult 
findings, an amendment to the protocol will be planned to study the strongest candidate SNP associations 
in this pediatric population.

Section 2.5 Overview of Proposed Pediatric Phase II Trial, Previous Text:
This is a two-stage open label phase II trial of pazopanib in children, adolescents and young adults with 
recurrent
or
refractory
solid
tumors. Tumors
of
primary
interest
are
rhabdomyosarcoma,
non-
rhabdomyosarcomatous soft tissue sarcoma (including synovial sarcoma, alveolar soft part sarcoma and 
desmoplastic small round cell tumor) and Ewing sarcoma. Tumors of secondary interest include 
hepatoblastoma, neuroblastoma (measurable and evaluable), and osteosarcoma.
Eligible patients will receive pazopanib daily as an oral tablet (450 mg/m2/dose) or as a powder for suspension
(160 mg/m2/dose) in 28 day cycles. The maximum dose to be administered daily is 800 mg. Patients will
be closely monitored with clinical and laboratory observations for adverse effects. Response will be evaluated
using appropriate imaging studies after the 2nd cycle of pazopanib, after the 4th cycle, and then every 3rd cycle
thereafter (baseline, prior to Cycle 3, prior to Cycle 5, prior to Cycle 8, prior to Cycle
11, etc). In the absence of severe toxicity or progressive disease, patients may continue receiving pazopanib 
for up to 2 years.
The study will be considered complete (analysis conducted and enrollment closed) when all subjects enrolled 
in the tumors of the primary interest strata have completed a minimum of 6 cycles of treatment, have disease 
progression, or have withdrawn from the study.
The first ten subjects enrolled on this trial will receive the suspension formulation during Cycle 1 with the 
option to change to the tablet formulation during Cycle 2 and subsequent cycles if they are able to swallow 
tablets and their BSA is > 0.48 m2. These subjects will have extended pharmacokinetic sampling with 
blood samples collected prior to dosing, 30 min, 1, 2, 4, 6, and 8 hours after the pazopanib dose on Days 1 
and 15 of Cycle 1. Additional blood samples for analysis of steady state trough plasma pazopanib 
concentrations will be collected prior to every subsequent odd cycle (in conjunction with safety labs). All 
subsequent subjects (regardless of formulation) will have blood samples for analysis of plasma pazopanib 
concentration collected prior to dosing and 3 to 4 hours after dosing on Day 15 of Cycle 1. Additional 
blood samples for analysis of steady state trough plasma pazopanib concentrations will be collected prior to 
every subsequent odd cycle (in conjunction with safety labs).
 
In addition, we will assess KDR polymorphism and pazopanib-
induced change in VEGFR2; VEGFA haplotypes and changes in VEGF-A, response rate, and overall survival;

Eligible patients will receive pazopanib daily as an oral tablet (450 mg/m2/dose) or as a powder for suspension
(160 225 mg/m2/dose) in 28 day cycles. The maximum dose to be administered daily for tablets is 800
mg and for suspension 400 mg. Patients will be closely monitored with clinical and laboratory observations 
for adverse effects. Response will be evaluated using appropriate imaging studies after the 2nd cycle of
pazopanib, after the 4th cycle, and then every 3rd cycle thereafter (baseline, prior to Cycle 3, prior to Cycle
5, prior to Cycle 8, prior to Cycle 11, etc). In the absence of severe toxicity or progressive disease, patients 
may continue receiving pazopanib forupto2years.
This study will dose patients requiring suspension with a starting dose of 225 mg/m2/dose.. The 
previously-defined suspension MTD of 160 mg/m2/dose may result in suboptimal exposure to 
demonstrate efficacy. Two of 4 patients in the prior Phase I study demonstrated DLTs in the form of
isolated and reversible Grade 3 elevations in ALT at 225 mg/m2/dose. Given that this toxicity was isolated
and reversible, the first 6 patients receiving suspension will be dosed at 225 mg/m2/dose and assessed for 
first-cycle DLTs before continuing to enroll additional patients requiring suspension. If two or more of
6 patients demonstrate DLT, then the dose may be de-escalated to the previously- defined MTD of 160
mg/m2/dose.

pazopanib tablets at a dose of 450 mg/m2/dose or as a powder in suspension at a dose of 160 mg/m2/dose (the
MTDs determined by Part 1 and Part 2A respectively of ADVL0815, the COG Phase I study). Note: The first
10 patients enrolled will receive the suspension formulation in Cycle 1 in order to obtain extended
pharmacokinetic sampling. These patients may then switch to tablet formulation in Cycle 2 and subsequent
cycles provided that they are able to swallow tablets and meet the required minimum BSA criteria for tablets
(see Section 3.2.3). Please note the difference in dosing for the tablet and suspension formulations (see 
above).
A cycle will be defined as 28 days with no rest periods between cycles. Patients may receive a maximum of
24 cycles. Patients with benefit (stable disease or an objective response) may continue therapy for up to 2 
years unless there is evidence of progressive disease or unacceptable treatment-related toxicity
Drug dosing for the tablet formulation should be determined using the dosing nomogram in Appendix II and
rounded to the nearest 50 mg. For patients receiving powder for suspension (50 mg/mL), the dose will be
rounded to the nearest 5 mg. Drug doses should be adjusted based on the BSA as determined by the height 
and weight obtained within 1 week prior to the beginning of each cycle.
Pazopanib should be taken on an empty stomach (at least 1 hour before a meal or 2 hours after a meal) at 
approximately the same time each day. Pazopanib tablets should be taken with clear liquids (approximately 
2-4 ounces for children < 12 years of age and 4-8 ounces for children ≥12 years of age). Pazopanib
suspension should be taken according to instructions in Appendix VII. The pazopanib suspension should be 
swirled for at least 30 seconds prior to removal of the dose from the bottle, which should be given 
immediately. If a patient vomits after a dose of pazopanib, the dose should not be repeated.
Section 4.1 Overview of Treatment Plan, Revised Text:
Pazopanib will be administered orally once daily on a continuous schedule. Patients will be treated with
pazopanibtablets as a tablet at a dose of 450 mg/m2/dose or as a powder in suspension at a dose of 160 225
mg/m2/dose.
450 mg/m2/dose was the MTD for tablet as determined by Part 1 and Part 2A, respectively
ADVL0815, the COG Phase I study, while the dose for oral suspension of 225 mg/m2/dose exceeds the
protocol-specified MTD of 160 mg/m2/dose established in that study. Two isolated and reversible
laboratory-defined DLTs were observed at 225 mg/m2/dose. The maximum dose to be administered
daily for tablets is 800 mg and for suspension 400 mg. Each cycle will be defined as 28 days.
Note: The first 10 6 patients enrolled will who receive the suspension formulationinCycle1 will be expected 
to complete extended PK sampling (Section 7.3.2) in order to obtain extended pharmacokineticsampling PK 
and safety data. These data will be reviewed prior to further enrollment of patients maythenswitchtotablet
formulationinCycle2andsubsequentcyclesprovidedthattheyare abletoswallowtabletsandmeettherequired
minimumBSAcriteriafortablets(seeSection3.2.3). Please note requiring suspension to determine if 225 
mg/m2/dose is tolerated and PK exposure is similar to exposure in adults associated with clinical efficacy.
If 225 mg/m2/dose is not tolerated (≥2 DLTs in 6 evaluable patients), the differenceindosing dose for the
tabletand patients who require suspension formulation(seeabove) may be reduced to 160 mg/m2/dose.
A cycle will be defined as 28 days with no rest periods between cycles. Patients mayreceiveamaximum of24
cycles. Patients with benefit (stable disease or an objective response) may continue therapy forupto 2years
unless there is evidence of progressive disease or unacceptable treatment-related toxicity.
Patients must remain on the same formulation of pazopanib throughout the duration of their protocol
therapy.
Drug dosing for the tablet formulation should be determined using the dosing nomogram in Appendix II 
androundedtothenearest50mg. For patients receiving powder for suspension (50 mg/mL), the dose will be
rounded to the nearest 5 mg. Drug doses should be adjusted based on the BSA as determined by the height

and weight obtained within 1 week prior to the beginning of each cycle.
Pazopanib should be taken on an empty stomach (at least 1 hour before a meal or 2 hours after a meal) at 
approximately the same time each day. Pazopanib tablets should be taken with clear liquids (approximately 
4 ounces for children < 12 years of age and 4-8 ounces for children ≥12 years of age). Pazopanib suspension 
should be taken according to instructions in Appendix VII. The pazopanib suspension should be swirled for 
at least 30 seconds prior to removal of the dose from the bottle, which should be given immediately. If a 
patient vomits after a dose of pazopanib, the dose should not be repeated.
A patient diary (see Appendices IA and IB) should be completed by the patient or their guardian and 
collected at the end of each cycle.
See Section 5.0 for Dose Modifications based on Toxicities
Section 4.1.1 Dose Reduction, Previous Text:
For patients who receive pazopanib tablets: A step-wise dose reduction will be allowed for toxicities as 
outlined in Section 5.0 for patients who recover to starting criteria as outlined in Section 4.2 within 7 days 
following planned administration (see dosing nomogram for tablets in Appendix II). The first dose reduction 
will be to 350 mg/m2/dose and then to 250 mg/m2/dose if necessary. If toxicity has not resolved at 250 
mg/m2/dose, a further dose reduction to 200 mg/m2/dose may be considered after discussion with the Study 
Chair.
For patients who receive pazopanib powder in suspension: A stepwise dose reduction will be allowed for 
toxicities as outlined in Section 5.0 for patients who recover to starting criteria as outlined in Section 4.2 
within 7 days following planned administration. The first dose reduction will be to 135 mg/m2/dose and 
then to 100 mg/m2/dose if necessary. If toxicity has not resolved at 100 mg/m2/dose, a further dose reduction 
to 75 mg/m2/dose may be considered after discussion with the Study Chair.

Section 4.1.2 Dose Escalation, Previous Text:
There will be no inter-patient dose escalation. However, following a dose modification for drug related 
toxicity and subsequent resolution of the toxicity the dose can then be increased step-wise back to initial 
starting dose using the same doses used to titrate down. The subject should be monitored for 1 0-14 days at 
each step to ensure that toxicity does not recur or worsen.

Section 4.1.3 Treatment Interruptions, Previous Text:
If a patient’s treatment has been interrupted for more than 14 days due to toxicity or for reasons other than 
toxicity (unplanned travel or vacation, or lack of transportation to the site), the Study chair must be 
notified to review the patient’s condition in order to resume treatment. In cases of toxicity, the re-challenge is
possible if the patient’s condition has been stable and has not deteriorated and the patient must have recovered 
from toxicity at the reduced dose level.
Section 4.1.3 Treatment Interruptions, Revised Text:
If a patient’s treatment has been interrupted for more than 14 days due to toxicity or for reasons other than 
toxicity (unplanned travel or vacation, or lack of transportation to the site), the Study Chair must be 
notified to review the patient’s condition in order to resume treatment. In cases of toxicity, the re-challenge at
a reduced dose is possible if the patient’s condition has been stable and has not deteriorated and the patient 
must have recovered from the toxicity atthereduceddoselevel.(Section 4.2)
Section 4.1.4.1 Management of Hypertension, Added Text (paragraph 2):
If patient is already on an anti-hypertensive medication at study enrollment, then their anti-hypertensive 
therapy should be adjusted (by either adjusting the dose of their current anti-hypertensive medication or 
by adding another anti-hypertensive agent) according to the algorithm in Section 5.4.1.
Section 4.1.4.3 Treatment of Palmer-Plantar Erythrodysesthesia (Hand-foot
Syndrome), Added Text:
Other supportive care measures for the treatment of hand-foot syndrome should be instituted as needed.

Section 4.2 Criteria for Starting Subsequent Cycles, Previous Text:

Novartis
Confidential
Page 124
Amended Protocol Version 05 Clean
Protocol No. VEG116731
A cycle may be repeated every 28 days if the patient has at least stable disease and has again met 
laboratory parameters as defined in the eligibility section, Section 3.2.7, does not have a dose limiting 
toxicity requiring permanent removal from protocol therapy (Section 5.1) or a toxicity requiring resolution 
prior to resuming study drug (eg: hypertension, hepatotoxicity, electrolyte abnormality, bleeding, wound 
healing, etc) as outlined in Section 5.0.
Section 4.2 Criteria for Starting Subsequent Cycles, Revised Text:
A cycle may be repeated every 28 days if the patient has at least stable disease and has again met 
laboratory parameters as defined in the eligibility section, Section 3.2.6 and, does not have a dose limiting 
toxicity requiring permanent removal from protocol therapy (Section 5.1)) or a toxicity requiring resolution
prior to resuming study drug (eg: A patient may resume study drug at the same or a reduced dose if 
they have a toxicity that is adequately managed (eg: myelosuppression, hypertension, hepatotoxicity, 
electrolyte abnormality, bleeding, wound healing, etc) as outlined in Section 5.0.
Section 4.4 Permitted Medications, Added Text (paragraph 4):
Anti-emetics (such as prochlorperazine, lorazepam, ondansetron or other 5-HT3 antagonists) may be 
administered prophylactically in the event of nausea. However, it is important to note that 5-HT3 blockers
that are given daily for a prolonged period of time may prolong QTc and should be used with caution. 
(Appendix IIIB). Anti-diarrheals, such as loperamide, may be administered as needed in the event of diarrhea. 
Although acetaminophen at doses of 2 g/day is permitted, it should be used with caution in subjects with 
impaired liver function.
Section 4.4 Permitted Medications – Use with Caution, Added Text:
Results from drug-drug interaction studies conducted in subjects with cancer suggest that pazopanib has no 
effect on the metabolism of S-warfarin. Hemorrhagic events, however, have been reported in clinical 
studies with pazopanib; therefore, pazopanib should be used with caution in subjects with increased risk of 
severe bleeding or who are benefitting from treatment and require the initiation of concomitant 
anticoagulant therapy (e.g., warfarin or its derivatives, low molecular weight heparin, unfractionated heparin)
while on study. Note: Subjects are excluded from enrolling on the study if they are taking therapeutic
doses of S-warfarin at the time of screening. Subjects taking concomitant anticoagulant therapy should be
monitored regularly for changes in relevant coagulation parameters as clinically indicated, as well as for any 
clinical bleeding episodes.
Section 4.5.4 Added Text:
Concomitant administration of pazopanib with esomeprazole decreases the bioavailability of pazopanib by 
40% (AUC and Cmax), and co-administration of pazopanib with medicines that increase gastric pH should be 
avoided. Co-administration of pazopanib with medicines that increase gastric pH is PROHIBITED from 
24 hours before the first dose of pazopanib until after the final PK blood sample is collected on Day 15 
± 1 day of Cycle 1. After this, if the concomitant use of a proton-pump inhibitor (PPI) is medically necessary, 
it is recommended that the dose of pazopanib be taken without food once daily in the evening concomitantly 
with the PPI (Section 4.8). If the concomitant administration of an H2-receptor antagonist is medically 
necessary, pazopanib should be taken without food at least 2 hours before or at least 10 hours after a dose of 
an H2-receptor antagonist. Pazopanib should be administered at least 1 hour before or 2 hours after 
administration of short-acting antacids.

pazopanib related hypertension. Should initiation of anti-hypertensive therapy be required, single agent therapy 
(commonly including the calcium channel blockers amlodipine or nifedipine, which are permissible without
notifying the study chair) should be started and the blood pressure should be monitored at least twice weekly

Section 4.5.6 Added Text:
Patients’ medications should be reviewed at eligibility, before treatment initiation, and during treatment.
Any concomitant medications that are “generally accepted” to cause a risk of Torsade de pointes are
prohibited (see Appendix IIIB). Those “associated” with a risk of QTc prolongation and/or Torsades de
pointes should be discontinued or replaced with drugs that do not carry these risks, if possible. Patients 
who must take these medications should be watched carefully for symptoms of QTc prolongation, such 
as syncope. Performing additional EKGs on patients who must take one or more of these medications is
recommended but not required, at the investigator’s discretion.
Section 4.8 Prohibited Medications, Added Text:

Glucocorticoidsforgreaterthan2weeksduration: cortisone (>50 mg), 
hydrocortisone (>40 mg), prednisone (>10 mg), methylprednisolone (>8 mg), 
dexamethasone (>1.5 mg)
Grapefruit or grapefruit juice is prohibited as it inhibits CYP3A4 activity and may also increase 
plasma concentrations of pazopanib.
As noted above, co-administration of pazopanib with medicines that increase gastric pH is 
prohibited from 24 hours before the first dose of pazopanib until after the final PK blood sample is 
collected on Day 15 ± 1 day of Cycle 1.

LFTs are reduced to Grade 1.
For isolated total bilirubin2 elevation without
concurrent ALT increase (defined as ALT < 3 x
ULN).
1. Isolated hyperbilirubinemia (in the absence of
elevated ALT or other signs/symptoms of liver 
injury) does not require dose modification.
Study treatment inhibits UGT1A1 and
OATP1B1, which can cause elevation of 
indirect (unconjugated) bilirubin in the absence
of liver injury.
2. If bilirubin is > 1.5 x ULN in the absence of
ALT elevation, fractionation of bilirubin should 
be performed. If the bilirubin is predominantly 
indirect (65%) indirect (unconjugated), 
continue study treatment at the same dose. If 
bilirubin is >35% direct (conjugated), study 
treatment may also be continued however,
further evaluation should be undertaken for 
underlying cause of cholestasis

14 days prior to surgery and for 14 days after surgery. Pazopanib should not be restarted if there is 
evidence of wound healing complications such as a wound infection. Patients who require surgery less
than 14 days from treatment with pazopanib should be monitored closely for wound complications. 
Patients who require major surgery during Cycle 1 of therapy must be removed from protocol therapy.

14. Females of childbearing potential require a negative serum pregnancy test prior to starting treatment.
Section 7.2.4 Pregnancy Testing and Reporting, Section Added:
The need for a screening pregnancy test depends on whether a female subject is of childbearing potential 
or non-childbearing potential. If a female subject is of childbearing potential, she must have a serum -
Human Chorionic Gonadotropin (-HCG) pregnancy test performed within 7 days prior to the first dose of 
study treatment(s). Subjects with a positive pregnancy test result must be excluded from the study. 
Subjects with a negative pregnancy test result must agree to use an effective contraception method as 
described below during the study until 30 days following the last dose of study treatment(s). Any pregnancy
that occurs during study participation must be reported using a clinical trial pregnancy form. To ensure
subject safety, each pregnancy must be reported to GSK within 2 weeks of learning of its occurrence. Study
treatment should be immediately discontinued if pregnancy occurs during study participation. The pregnancy
must be followed up to determine outcome (including premature termination) and status of mother and child. 
Pregnancy complications and elective terminations for medical reasons must be reported as an AE or SAE.
Spontaneous abortions must be reported as an SAE.
Any SAE occurring in association with a pregnancy brought to the investigator’s attention after the subject 
has completed the study and considered by the investigator as possibly related to the study treatment(s), must 
be promptly reported to GSK.
In addition, the investigator must attempt to collect pregnancy information on any female partners of male 
study subjects who become pregnant while the subject is enrolled in the study. Pregnancy information 
must be reported to GSK as described above.
Section 7.3.2 Sampling Schedule, Previous Text (paragraph 2):
Extended pharmacokinetic sampling will be done in the first 10 patients enrolled (who will all receive the

pazopanib concentration collected at the following time points on Day 1 of Cycle 1: pre-dose, 30 min, 1 hour,
2 hours, 4 hours, 6 hours, and 8 hours after the dose. Samples will also be obtained on Day 15 ± 1 day of 
Cycle 1: pre-dose, 30 min, 1 hour, 2 hours, 4 hours, 6 hours, and 8 hours after the dose. Additional blood
samples for analysis of steady-state trough plasma pazopanib concentrations will be obtained prior to the 
start of every odd cycle. The pre-dose sample on Day 15, Cycle 1 and trough plasma concentrations
should be obtained between 22-26 hours after the previous dose of pazopanib. Subjects should be 
instructed to hold their dose of pazopanib on the day that a pre-dose concentration is to be collected. These 
specimens should correspond to the timing of routine laboratory evaluations.

List of Abbreviations, Added Table
Experimental Design Schema Previous Text:
Pazopanib will be administered orally once daily as a tablet at 450 mg/m2/dose or as a powder in suspension at
225 mg/m2/dose. The maximum tolerated dose (MTD) for tablets was 450 mg/m2/dose as determined by 
ADVL0815, the COG Phase I study, while the dose for oral suspension of 225 mg/m2/dose exceeds the protocol-
specified MTD of 160 mg/m2/dose established in that study. The 225 mg/m2/dose is where two isolated
laboratory-defined dose-limiting toxicities (DLTs) were observed. The maximum dose to be administered daily
for tablets is 800 mg. The maximum dose to be administered daily for suspension is
400 mg. Each cycle will be defined as 28 days.
The first 6 patients enrolled who receive suspension will be expected to complete extended pharmacokinetic (PK)
sampling (Section 7.3.2) in order to obtain PK and safety data. These data will be reviewed prior to further
enrollment of patients requiring suspension to determine if 225 mg/m2/dose is tolerated and PK exposure is
similar to exposure in adults associated with clinical efficacy. If the 225 mg/m2/dose is not tolerated (≥2
dose limiting toxicities (DLTs) in 6 evaluable patients), the dose for patients who require suspension may be 
reduced to 160 mg/m2/dose.
Patients with benefit (stable disease or an objective response) may continue therapy (in the absence of unacceptable
treatment related toxicity) unless there is evidence of progressive disease or unacceptable treatment-related toxicity.
Experimental Design Schema Revised Text:
This is an open label phase II trial designed to primarily assess the efficacy of pazopanib in children, adolescents 
and young adults with recurrent or refractory solid tumors. Patients will receive pazopanib monotherapy and the
term “protocol therapy” will be used throughout this document to designate pazopanib
monotherapy.
Pazopanib will be dosed daily as an oral tablet (450 mg/m2/dose, maximum 800 mg) or as an oral powder for 
suspension (225 mg/m2/dose, maximum 400 mg). Each cycle will be defined as 28 days, with no rest periods 
between cycles.
The first patients enrolled who receive powder suspension will be expected to complete extended pharmacokinetic 
(PK) sampling (Section 7.3.2) in order to obtain PK and safety data in 6 evaluable patients. If the 225 mg/m2/dose 
is not tolerated (≥2 patients with dose limiting toxicities (DLTs) in the first 6 evaluable patients), subsequent new 
patients will be enrolled at the160 mg/m2/dose level until 6 evaluable patients are available for the safety review 
and the PK analysis.
Patients with benefit (stable disease or an objective response) may continue therapy unless there is evidence of 
progressive disease, unacceptable treatment-related toxicity, until death or until study closure [defined as 1 
year after Last Patient First Visit (LPFV)], whichever occurs first.

Section 1.1 Primary Aims, Revised Text:
1.1.1
To determine the investigator- assessed objective response rate of pazopanib in children, adolescents 
and young adults (patients) with relapsed or refractory solid tumors of the following types (each defining a cohort):
1. rhabdomyosarcoma,
2. non-rhabdomyosarcomatous soft tissue sarcoma, or
3. Ewing sarcoma/peripheral Primitive Neuro Ectodermal Tumor (PNET).
Section 1.2 Secondary Aims, Previous Text:
1.2.8

with pazopanib.
Section 1.2 Secondary Aims, Revised Text:
1.2.8 To further assess VEGF-A and KDR genotype, their plasma concentration relationships in patients
with cancer treated with pazopanib.
1.2.10 To assess overall survival (OS) in patients with relapsed or refractory solid tumors per cohort
(described under Section 1.1.1 and 1.2.1).
Section 2.5 Overview of Proposed Pediatric Phase II Trial, Previous Text:
This is a two-stage open label phase II trial of pazopanib in children, adolescents and young adults with recurrent 
or refractory solid tumors. Tumors of primary interest are rhabdomyosarcoma, non-
rhabdomyosarcomatous soft tissue sarcoma (including synovial sarcoma, alveolar soft part sarcoma and 
desmoplastic small round cell tumor) and Ewing sarcoma. Tumors of secondary interest include hepatoblastoma, 
neuroblastoma (measurable and evaluable), and osteosarcoma.
Eligible patients will receive pazopanib daily as an oral tablet (450 mg/m2/dose) or as a powder for suspension
(225 mg/m2/dose) in 28 day cycles. The maximum dose to be administered daily for tablets is
800 mg and for suspension 400 mg. Patients will be closely monitored with clinical and laboratory
observations for adverse effects. Response will be evaluated using appropriate imaging studies after the
2nd cycle of pazopanib, after the 4th cycle, and then every 3rd cycle thereafter (baseline, prior to Cycle 3, prior
to Cycle 5, prior to Cycle 8, prior to Cycle 11, etc). In the absence of severe toxicity or progressive disease, 
patients may continue receiving pazopanib.
This study will dose patients requiring suspension with a starting dose of 225 mg/m2/dose.. The previously-defined
suspension MTD of 160 mg/m2/dose may result in suboptimal exposure to demonstrate efficacy. Two of 4
patients in the prior Phase I study demonstrated DLTs in the form of isolated and reversible Grade 3 elevations 
in ALT at 225 mg/m2/dose. Given that this toxicity was isolated and reversible, the first 6 patients receiving
suspension will be dosed at 225 mg/m2/dose and assessed for first- cycle DLTs before continuing to enroll
additional patients requiring suspension. If two or more of 6 patients demonstrate DLT, then the dose may be de-
escalated to the previously-defined MTD of 160 mg/m2/dose.
The first 6 subjects who require the suspension formulation will have extended PK sampling with blood samples
collected prior to dosing, 30 min, 1, 2, 4, 6, and 8 hours after the pazopanib dose on Days 1 and 15 of Cycle
1. All subjects (regardless of formulation) will have blood samples for analysis of plasma pazopanib 
concentration collected prior to dosing and 3 to 4 hours after dosing on Day 15 of Cycle 1. Additional blood 
samples for analysis of steady state trough plasma pazopanib concentrations will be collected prior to every 
subsequent odd cycle (in conjunction with safety labs).
(PlGF), VEGFR2, and endoglin. In addition, we will assess KDR polymorphism and pazopanib-induced 
change in VEGFR2; VEGFA genotype/haplotypes and changes in VEGF-A, response rate, and overall survival;
and candidate SNPs and clinical endpoints as identified in ongoing large scale studies of pazopanib in the adult 
population.

The study will be considered complete (analysis conducted and enrollment closed) when all subjects enrolled in 
the tumors of the primary interest strata have completed a minimum of 6 cycles of treatment, have disease
progression, or have withdrawn from the study.
Section 2.5 Overview of Proposed Pediatric Phase II Trial, Revised Text:
This is a two-stage open label phase II trial of pazopanib in children, adolescents and young adults with recurrent 
or refractory solid tumors. Tumors of primary interest are rhabdomyosarcoma, non-
rhabdomyosarcomatous soft tissue sarcoma (including synovial sarcoma, alveolar soft part sarcoma and 
desmoplastic small round cell tumor) and Ewing sarcoma/peripheral PNET. Tumors of secondary interest
include hepatoblastoma, neuroblastoma (measurable and evaluable), and osteosarcoma.
Each tumor type defines a cohort resulting in 7 total cohorts. The first stage of the study involves enrolling an 
initial 10 patients into each cohort. The response rate will be determined for each cohort after the target enrollment
of 10 patients is reached for that cohort. If one or more confirmed responses are observed in the first 10
evaluable patients in a cohort, an additional 10 patients will be enrolled into that cohort in the second stage of
study. Thus, for cohort(s) with one or more confirmed responses in the first stage of study, a total of 20 patients 
will be enrolled and evaluated to determine efficacy.
Eligible patients will receive pazopanib monotherapy. Pazopanib will be dosed daily as an oral tablet (450 
mg/m2/dose, maximum 800 mg) or as a powder for oral suspension (225 mg/m2/dose, maximum 400 mg) in 28 
day cycles.
The MTD for pazopanib tablets was 450 mg/m2/dose as determined by ADVL0815/PZP114411, the COG 
Phase I study in children with relapsed or refractory solid tumors. For the powder suspension formulation, the 
selected starting dose is higher than the protocol-defined MTD of 160 mg/m2/dose established in ADVL0815. This 
decision is driven by the considerations that the 160 mg/m2/dose may result in exposure that is suboptimal to
demonstrate efficacy and that only two isolated and reversible laboratory-defined DLTs were observed at the 
225 mg/m2/dose.
The first patients who are enrolled to receive pazopanib as powder suspension at 225 mg/m2/dose daily will be 
closely monitored for safety and for the occurrence of dose-limiting toxicity during the first cycle (28 days) of 
therapy. Patients who either receive 225 mg/m2/dose daily for at least 24 days (85% of the dose for a 28- day 
cycle with powder suspension at 225 mg/m2/dose) or are withdrawn from dosing due to one or more protocol-
defined dose-limiting toxicities (Section 5.1) during the first cycle will be considered evaluable for the purpose of 
this safety review. Six evaluable patients are required.
The first patients enrolled to receive powder suspension at 225 mg/m2/dose will also be expected to complete 
extended PK sampling (Section 7.3.2) with blood samples collected prior to dosing, and 30 min, 1, 2, 4, 6, and 8
hours after the pazopanib dose on Day 1 and Day 15 ± 1 day of Cycle 1 (with no pazopanib dose
modification or adjustment in the 10 days before Cycle 1 Day 15 sample collection). Patients who can provide 
adequate blood samples for the 2 scheduled extended PK collections will be considered to be evaluable 
patients for the purpose of this PK analysis, and PK data are required from 6 evaluable patients. If one or more of
the first 6 patients fails to provide blood samples as specified in the protocol or if it is known that for some reason
a patient’s collected blood sample(s) cannot be analyzed, that patient will be determined to be non- evaluable 
for this analysis, and one or more additional patients will be enrolled for treatment with pazopanib as powder 
suspension for the purpose of obtaining the extended PK samples.
Because patients receiving the powder suspension enrolled in the safety review group may be different from those 
in the PK analysis group, enrollment onto powder suspension may follow several different paths:

If ≥2 out of 6 evaluable patients have dose- limiting toxicities (DLT and as defined in 
Section 5.1) within the first cycle, then enrollment onto 225 mg/m2/dose pazopanib will be 
halted. Subsequent new patients will be enrolled at the 160 mg/m2/dose level until 6 evaluable
patients from this dose group are available for the safety review and 6 patients are available 

Novartis
Confidential
Page 140
Amended Protocol Version 05 Clean
Protocol No. VEG116731
for PK analysis at 160 mg/m2/dose.

If 6 PK evaluable patients are enrolled prior to enrollment of 6 patients who are evaluable for 
the safety review, the extended PK sample collection may be suspended.

If < 2 DLTs are observed during the first cycle in 6 patients evaluable for safety at 225 
mg/m2/dose and these 6 patients are not all evaluable for the PK analysis, then enrollment 
will continue until 6 PK evaluable patients are available.
All patients will be closely monitored with clinical and laboratory observations for adverse effects.
Tumor response will be evaluated using appropriate imaging assessments at baseline, prior to Cycle 3, Cycle 5, 
Cycle 8, Cycle 11 and then every 3rd cycle thereafter.
 
In addition, we will assess KDR polymorphism and pazopanib-induced change
in soluble VEGFR2; VEGF-A genotype and changes in VEGF-A concentration; KDR and VEGF-A genotypes
and response rate, and progression-free survival; and candidate SNPs and clinical endpoints as identified in the 
adult population.
The primary analysis will be performed 20 weeks after the last patient’s first visit in the three cohorts of primary
interest (rhabdomyosarcoma, non-rhabdomyosarcomatous soft tissue sarcoma and Ewing sarcoma/peripheral 
PNET).
The study will be completed one year from the date of the last patient’s first visit and the end of study analysis 
will be performed at the time of study completion.
For patients who are still on treatment and continue to derive benefit from it at the time of study completion, 
and for whom no other treatment options are available, Novartis will discuss individual patient cases with

(rhabdomyosarcoma, non-rhabdomyosarcomatous soft tissue sarcoma, Ewing sarcoma/peripheral PNET,
osteosarcoma, neuroblastoma (measureable), neuroblastoma (evaluable) or hepatoblastoma), each patient will then 
be registered into the interactive voice response system RAMOS (Registration and Medication Ordering System). 
RAMOS will then provide an identification number consistent with the patient’s tumor type.
All calls to RAMOS are confirmed (with a fax or e-mail), which will be sent to the site upon completion of 
each call. Study-specific instructional worksheets will be provided for the use of RAMOS in the Study Procedures 
Manual.
Section 3.1.2 Patient Rescreening, Added Text:
Patients may be rescreened if the reasons for the initial screen failure were non-medical or if the medical issues 
leading to screen failure have resolved. Approval by the Study Chair is required prior to rescreening. A new 
informed consent form must be signed. Please refer to detailed instructions in the Study Procedure Manual for 
rescreening.
Section 3.1.4 Study Enrollment Status, Added Text:
While the study remains open for enrollment, enrollment into each cohort will proceed independently from the 
other cohorts (see Section 9.2 for details). The enrollment in the cohorts of secondary interest may remain 
open if after review of the data, an efficacy signal is seen.

Section 4.1 Overview of Treatment Plan, Previous Text
Pazopanib will be administered orally once daily as a tablet at a dose of 450 mg/m2/dose or as a powder in
suspension at a dose of 225 mg/m2/dose. 450 mg/m2/dose was the MTD for tablet as determined by 
ADVL0815, the COG Phase I study, while the dose for oral suspension of 225 mg/m2/dose exceeds the 
protocol-specified MTD of 160 mg/m2/dose established in that study. Two isolated and reversible laboratory-
defined DLTs were observed at 225 mg/m2/dose. The maximum dose to be administered daily for tablets is
800 mg and for suspension 400 mg. Each cycle will be defined as 28 days.
Note: The first 6 patients enrolled who receive suspension will be expected to complete extended PK sampling
(Section 7.3.2) in order to obtain PK and safety data. These data will be reviewed prior to further enrollment
of patients requiring suspension to determine if 225 mg/m2/dose is tolerated and PK exposure is similar to
exposure in adults associated with clinical efficacy. If 225 mg/m2/dose is not tolerated (≥2 DLTs in 6
evaluable patients), the dose for patients who require suspension may be reduced to 160 mg/m2/dose.
A cycle will be defined as 28 days with no rest periods between cycles. Patients with benefit (stable 
disease or an objective response) may continue therapy unless there is evidence of progressive disease or 
unacceptable treatment-related toxicity.
Patients must remain on the same formulation of pazopanib throughout the duration of their protocol
therapy.
Drug dosing for the tablet formulation should be determined using the dosing nomogram in Appendix II. 
For patients receiving powder for suspension (50 mg/mL), the dose will be rounded to the nearest 5 mg. 
Drug doses should be adjusted based on the BSA as determined by the height and weight obtained within 1
week prior to the beginning of each cycle.
Pazopanib should be taken on an empty stomach (at least 1 hour before a meal or 2 hours after a meal) at 
approximately the same time each day. Pazopanib tablets should be taken with clear liquids (approximately 4 
ounces for children < 12 years of age and 4-8 ounces for children ≥12 years of age). Pazopanib suspension
should be taken according to instructions in Appendix VII. The pazopanib suspension should be swirled for
at least 30 seconds prior to removal of the dose from the bottle, which should be given immediately. If a 
patient vomits after a dose of pazopanib, the dose should not be repeated.
A patient diary (see Appendices IA and IB) should be completed by the patient or their guardian and 
collected at the end of each cycle.
Section 4.1 Overview of Treatment Plan, Revised Text
Pazopanib will be dosed daily as an oral tablet at 450 mg/m2/dose or as a powder for oral suspension at 225 
mg/m2/dose.
For the tablet formulation, the maximum
tolerated
dose (MTD) was 450 mg/m2/dose as determined by
ADVL0815/PZP114411, the COG Phase I study. The maximum dose to be administered daily for tablets is
800 mg.
For the powder suspension formulation, the selected starting dose is 225 mg/m2/dose, higher than the protocol-
specified MTD of 160 mg/m2/dose established in study ADVL0815. This decision is driven by the considerations
that the 160 mg/m2/dose may result in exposure that is suboptimal to demonstrate efficacy and that only two
isolated and reversible laboratory-defined dose-limiting toxicities (DLTs) were observed at the 225 mg/m2/dose.
The maximum dose to be administered daily for oral suspension is 400 mg.

Note: The first patients enrolled who receive powder suspension will be reviewed for safety and will be expected 
to complete extended PK sampling (Section 7.3.2). A minimum of 6 evaluable patients for safety and 6 evaluable
patients for PK are required as described in section 2.5. Safety and PK data from these patients will be reviewed 
prior to further enrollment of patients requiring powder suspension to determine if the 225 mg/m2/dose is tolerated
and if the PK exposure is similar to exposure in adults associated with clinical efficacy. If 225 mg/m2/dose
is not tolerated (≥2 patients with DLTs in the first 6 evaluable patients during their first cycle), all subsequently
enrolled patients will receive 160 mg/m2/dose, and an additional 6 subjects will be assessed for safety and PK.
Patients will take pazopanib continuously, once daily. A cycle will be defined as 28 days with no rest periods 
between cycles. Patients with benefit (stable disease or an objective response) may continue therapy unless there
is evidence of progressive disease or unacceptable treatment-related toxicity, death or until study closure defined 
as 1 year after Last Patient First Visit.
Patients must remain on the same formulation of pazopanib throughout the duration of their protocol 
therapy.
Drug dosing for the tablet formulation should be determined using the dosing nomogram in Appendix II. For 
patients receiving powder for suspension (50 mg/mL), the dose will be rounded to the nearest 5 mg. Drug 
doses should be adjusted based on the BSA as determined by the height and weight obtained within 1 week 
prior to the beginning of each cycle.
Pazopanib should be taken on an empty stomach (at least 1 hour before a meal or 2 hours after a meal) at 
approximately the same time each day. Pazopanib tablets should be taken with clear liquids (approximately 4

Abdominal pain is not an uncommon symptom with vascular endothelial growth factor (VEGF) receptor 
antagonists, of which pazopanib is one. Bowel perforations have been reported in clinical trials of pazopanib
and with other agents in this class. Bowel perforations have been associated in some patients with tumor 
in the bowel wall, or diverticulitis, while in others there has been no clear explanation. Although bowel
perforation is a rare event, investigators and study staff at the site are advised to be vigilant of this potential
complication in patients receiving pazopanib. Please contact the Study chair if you need further guidance or 
would like to discuss an event involving abdominal pain or bowel perforations.

Section 7.3.2 Sampling schedule, Revised Text
All patients (whether receiving pazopanib as tablet or as oral powder suspension) will have a blood sample for 
analysis of the plasma pazopanib concentration collected prior to the first dose on Day 1 of Cycle 1. In addition,
all patients will have 2 blood samples collected on Day 15 ± 1 day of Cycle 1: one sample prior to the dose and 
one sample 3-4 hours after dosing.
Blood samples for analysis of steady-state trough plasma pazopanib concentrations will also be obtained prior
to the start of every subsequent odd-numbered cycle (that is, pre-dose prior to Cycle 3, pre-dose prior to Cycle
5, etc). These steady-state trough plasma concentration samples can be collected between Day 22 of the
previous cycle to Day 1 of the odd-numbered cycle, and the actual date and time of sample collection 
recorded on the PK sample collection form.
The pre-dose sample on Day 15 ± 1 day of Cycle 1 and the trough plasma concentration samples takenprior
to dosing for every odd-numbered cycle should be obtained between 22-26 hours after thepreviousdoseof
pazopanib. Patients should be instructed to hold their dose of pazopanib on the day that a pre-dose PK sample
is to be collected. Collection of these PK samples should correspond to the timing of routine laboratory 
evaluations.
Extended PK sampling will be done during Cycle 1 in the first patients who receive the powder suspension 
formulation, until 6 patients are considered evaluable for the PK analysis. These patients will have a blood 
sample for analysis of the plasma pazopanib concentration collected at the following time points on Day 1 of
Cycle 1: pre-dose and at 30 min, 1 hour, 2 hours, 4 hours, 6 hours, and 8 hours after the dose. Samples will also
be obtained on Day 15 ± 1 day of Cycle 1: pre-dose and at 30 min, 1 hour, 2 hours, 4 hours, 6 hours, and 8 hours
after the dose. If one or more of these 6 patients fail to provide blood samples as specified in the protocol or if 
it is known that for some reason a patient’s collected blood sample(s) cannot be analyzed, that patient(s) will
be determined to be non-evaluable for this analysis and one or more additional patients will be enrolled for 
treatment with pazopanib as powder for oral suspension and provision of the extended PK samples. These
patients will also provide blood samples for analysis of steady-state trough plasma pazopanib concentrations 
prior to the start of every subsequent odd-numbered cycle as described in the preceding paragraph.
Pazopanib dosing of either tablet or powder suspension must have continued uninterrupted and at the same dose 
level for at least 10 days prior to acquisition of the Cycle 1 Day 15 PK samples. If pazopanib dosing has been
interrupted or modified <10 days prior to Cycle 1 Day 15, then the PK samples should be taken between Cycle
1 Day 15 and Cycle 1 Day 22 on a study day that meets the condition of at least 10 consecutive days of dosing
at the same dose level. The Cycle 1 Day 15 PK kit should be used and the actual date and time of sample 
collections should be recorded in the eCRF.
If ≥2 out of 6 evaluable patients have dose-limiting toxicities as defined in Section 5.1) during the first cycle, 
then enrollment at the 225 mg/m2/dose dose level of pazopanib oral suspension will be halted. Subsequent new 
patients will be enrolled at the 160mg/m2/dose level until 6 evaluable patients from this dose group are available 
for the safety review and 6 patients are available for PK analysis.

Section 9.6 Interim Analysis, Previous Text
No formal interim analysis is planned outside of the study design. The study team will review safety data 
periodically over the course of the study.
Expansion of tumor specific cohorts will be done when there is at least one investigator determined confirmed
response in that cohort/strata within the first 10 enrolled patients. The time point for the decision to
expand will be the earliest of the following: an investigator determined confirmed response within the first
10 pts, the time when the first 10 patients are no longer eligible for obtaining a response (i.e., 18 weeks
have elapsed and a response is unlikely, has progressed, has discontinued therapy, has withdrawn consent).
Therefore, the clinical cut off for analysis purposes per cohort/strata, will be the earliest of 18 weeks from 
last subject first visit, all subjects have documented radiological progression or withdrawn consent from the 
study.
Section 9.6 Primary Analysis and End of Study Analysis, Revised Text
No formal interim analysis is planned outside of the study design. The study team will review safety data 
periodically over the course of the study.
Expansion of tumor specific cohorts will be done when there is at least one investigator determined confirmed
response in that cohort within the first 10 enrolled patients. A given tumor specific cohort will not be expanded 
if all the patients in the cohort have:

Progressed

Discontinued therapy

Withdrawn consent

Been determined to be lost-to-follow-up

Or have been treated for at least 20 weeks, making it unlikely that a response

Section 9.10 Evaluability for Toxicity, Deleted Text
All patients who receive at least one dose of pazopanib will be considered in the evaluation of 
toxicity.
Monitoring for Excessive Toxicity
A patient will be considered for toxicity monitoring if one of the following occurs: (1)
complete one cycle of pazopanib; (2) die on protocol therapy for a reason considered possibly,
probably or likely related to pazopanib; or (3) are removed from protocol therapy because of an adverse 
experience possibly, probably or likely related to pazopanib. A toxicity-evaluable patient will be considered
in the analysis during the interval from study enrollment until protocol therapy is terminated or a dose-
limiting toxicity is observed. A toxicity-evaluable patient will be considered to have experienced an
excessive toxicity event if: (1) the patient dies on protocol therapy for a reason considered possibly,
probably or likely related to pazopanib; or (2) experiences a dose- limiting toxicity.
The analytic unit for monitoring for excessive toxicity will be the patient-cycle: Each cycle where the 
patient receives at least 24 doses of pazopanib (approximately 85% of planned therapy) or where an 
excessive toxicity event is observed will be considered in the analysis. Onar-Thomas and Xiong 
demonstrate that, over typical dose-toxicity relationships the Rolling-6 methodology identifies, with 
probability approximately 95%, an MTD with a first-cycle-DLT probability less than or equal to 
30%.44 If there is overwhelming evidence that the dose selected for this trial has a per-cycle- DLT
probability of more than 30%, we will identify the regimen to the COG Phase I and II DSMC, DVL
leadership and CTEP as associated with a toxicity profile that may require modification of the regimen.
We will use a Bayesian rule to monitor for excessive toxicity.45,46 We will assume a beta prior 
distribution with α=0.6 and β=1.4. At least once per month, we will calculate:
Where n is the number of excessive-toxicity-evaluable cycles and x is the number of such cycles on which
an excessive toxicity event is observed. If this posterior probability exceeds 80%, we will identify the
regimen to the COG Phase I and II DSMC, DVL leadership and CTEP as associated with a toxicity profile
that may require modification of the regimen. Examples of situations in which this rule will indicate 
excessive toxicity have been noted and are presented below:

Section 9.12 Analysis of the Pharmacokinetic Parameters, Previous Text
Plasma pazopanib concentrations observed after administration of the suspension in the first 6 subjects
enrolled in the study will be analyzed with standard noncomparetmental methods using
WinNonlin version 5.2 or higher. The parameters maximum plasma pazopanib concentration (Cmax), the
time to Cmax (tmax), and the area under the curve (AUC) from zero to the time of the last quantifiable
concentration (AUC(0-t)) will be calculated, The AUC from zero to 24 hours after
administration (AUC(0-24)) on Day 15 will be calculated by using the predose plasma pazopanib 
concentration for the concentration 24 hours after dosing.
A mixed-effects model generated with data from adult subjects with solid tumors will be fit to the plasma
pazopanib concentration-time data to generate post-hoc estimates of pharmacokinetic parameters using 
NONMEM VII. The post-hoc estimates of pharmacokinetic parameters will be compared to the parameters
generated from data in adult subjects with cancer.
The change in plasma trough pazopanib concentrations will be characterized at the first cycle and each odd cycle
after the first. The effect of cycle on change in plasma trough concentrations will be assessed by fitting the 
parametric model:
Section 9.11 Analysis of the Pharmacokinetic Parameters, Revised Text
Plasma pazopanib concentrations observed in the first 6 patients who receive pazopanib as powder for oral 
suspension and are evaluable for pharmacokinetics will be analyzed with standard noncompartmental methods
using WinNonlin version 5.2 or higher. Parameter values for maximum plasma pazopanib concentration (Cmax),
the time to Cmax (tmax), and the area under the curve (AUC) from zero to the time of the last quantifiable
concentration (AUC(0-t)) will be calculated. The AUC from zero to 24 hours after administration (AUC (0-24))
on Day 15 will be calculated by using the predose plasma pazopanib concentration as the concentration 24 hours 
after dosing. The analysis to assess pazopanib pharmacokinetics after administration of the suspension prior to
continuing
enrollment
on
suspension
may be
performed
using
scheduled time. Calculations
of
noncompartmental parameter values for the final analysis will be based on actual sampling times.
Plasma pazopanib concentration values at each sampling occasion will be summarized by cohort as well as 
after combining the data from all cohorts, separately for each formulation and each dose level, if needed. 
In addition, plasma pazopanib concentration values at each sampling occasion will be summarized by age 
subgroups (2 to <12 years old, 12 to 18 years old) for each formulation and dose level, if needed. This 
analysis will combine data across all disease cohorts unless pharmacokinetic differences between the cohorts 
are observed.
The pharmacokinetic parameter values in the patients with extended sampling will be summarized for 
Cycle 1 Day 1 and Cycle 1 Day 15, combining data from all patients, separately by dose level, if needed.
Section 9.12 Analysis of Biological and Correlative Endpoints, Deleted Text
Objective 1.2.3 will be assessed by examining the change in biological parameter between the samples 
taken on Days 1 and 15. Initially, such analyses will not be segregated by tumor type. The null hypothesis 
H0: No change in median value of the biological parameter between Day 1 and 15 will be assessed by the 
Wilcoxon signed rank test. The power associated with this test as a function of the variability of the biological

Section 10.8 Survival Follow-up, Added Text
Patients who have discontinued protocol therapy will be followed for Survival status. The investigator site 
will collect and report Survival follow-up in the eCRF every 3 months, which would include the patient’s 
survival status and any antineoplastic therapies taken since discontinuation of protocol therapy, until death, 
lost to follow-up, or withdrawal of consent from survival follow-up occurs or final cut-off for survival 
analysis.
The date and cause of death should be recorded in the eCRF.

AEs will be collected from the start of Study Treatment and until completion of the final 30 day study 
visit.
Section 11 Adverse Event (AE) and Serious Adverse Event (SAE), Revised Text
AEs will be collected from the start of protocol therapy and until 28 days following last dose of protocol
therapy.
Medical occurrences that begin prior to the start of protocol therapy but after obtaining informed consent 
should be recorded on the Medical History/Current Medical Conditions section of the eCRF.
Any new primary cancer must be recorded as an SAE and will be recorded from the time a patient
consents to participate in the study up to and including any follow-up contact.

termed ‘Hy’s Law’ events (INR measurement is not required and the threshold value stated will not apply 
to patients receiving anticoagulants).
Section 11.4 Disease-Related Events and/or Disease-Related Outcomes Not Qualifying as SAEs, 
Added Text
An event which is part of the natural course of the disease under study (i.e., disease progression or
hospitalization due to disease progression) does not need to be reported as an SAE. Death due to disease 
under study is to be recorded on the Death eCRF form. However, 
if 
the 
underlying 
disease 
(i.e., 
progression) is greater than that which would normally be expected for the patient, or if the investigator 
considers that there was a causal relationship between treatment with study medication(s) or protocol 
design/procedures and the disease progression, then this must be reported as an SAE.
Section 11.5 Recording of AEs and SAEs, Deleted Text
Subject-completed health outcomes questionnaires and the collection of AE data are independent 
components of the study. Responses to each question in the health outcomes questionnaire will be 
treated in accordance with standard scoring and statistical procedures detailed by the scale’s developer.

Original Text:
No study-specific procedure will start before  the signature of the informed consent  form (and assent,  
according  to institutional  guidelines),  defining  the study entry.
Prior to enrollment on study, patients must be  assigned a COG patient ID number. This number is
obtained once authorization for the release of protected health information (PHI) has been obtained. The COG
patient ID number is used to identify the patient in all future interactions with COG. If you have problems 
with registration, please refer to the online help.
Upon completion of all required baseline assessments, the investigator or authorized site staff will assign each
eligible patient a Sponsor study-specific patient identification number. Each site will be assigned a range of
patient numbers, and this information is provided in the Study Procedure Manual (SPM). The patient ID
number consists of 6 digits including leading zeros. Using this patient ID number and patient’s histology cohort 
(rhabdomyosarcoma, non- rhabdomyosarcomatous soft tissue sarcoma, Ewing sarcoma/peripheral PNET, 
osteosarcoma, neuroblastoma (measureable), neuroblastoma (evaluable) or hepatoblastoma), each patient will 
then be registered into the interactive voice response system RAMOS (Registration and Medication Ordering 
System). RAMOS will then provide an identification number consistent with the patient’s tumor type.
All calls to RAMOS are confirmed (with a fax or e-mail), which will be sent to the site upon completion of
each call. Study-specific instructional worksheets will be provided for the use of RAMOS in the Study 
Procedures Manual.

Section: 7.2.4, Pregnancy Testing and Reporting
Original Text:
The need for a screening pregnancy test depends on whether a female patient is of childbearing potential or
non-childbearing potential. If a female patient is of childbearing potential, she must have a serum -Human
Chorionic Gonadotropin (%-HCG) pregnancy test performed within 7 days prior to the first dose of study 
treatment(s). Patients with a positive pregnancy test result must be excluded from the study. Patients with a 
negative pregnancy test result must agree to use an adequate contraception method as described below during
the study until 30 days following the last dose of study treatment(s). Any pregnancy that occurs during study
participation must be reported using a clinical trial pregnancy form. To ensure patient safety, each 
pregnancy must be reported to GSK within 2 weeks of learning of its occurrence. Study treatment should be 
immediately discontinued if pregnancy occurs during study participation. The pregnancy must be followed up 
to determine outcome (including premature termination) and status of mother and child.
Pregnancy
complications and elective terminations for medical reasons must be reported as an AE or SAE (Section 
11.8). Spontaneous abortions must be reported as an SAE.

Any SAE occurring in association with a pregnancy brought to the investigator’s attention after the patient
has completed the study and considered by the investigator as possibly related  to the study treatment(s) 
must be promptly reported to GSK.
Any SAE occurring as a result of a post-study pregnancy which is considered reasonably related to the study
treatment by the investigator, will be reported to the Sponsor. While the investigator is not obligated to actively 
seek this information in former study participants, he or she may learn of an SAE through spontaneous 
reporting.
In addition, the investigator must attempt to collect pregnancy information on any female partners of
male study subjects who become pregnant while the subject is enrolled in the study. Pregnancy information
must be reported to GSK as described above.

must be followed up to determine outcome (including premature termination) and status of mother and child.
Pregnancy complications and elective terminations for medical reasons must be reported as an AE or SAE 
(Section 11.8). Spontaneous abortions must be reported as an SAE.
Any SAE occurring in association with a pregnancy brought to the investigator’s attention after the patient
has completed the study and considered by the investigator as possibly related  to the study treatment(s) 
must be promptly reported to NovartisGSK.
Any SAE occurring as a result of a post-study pregnancy which is considered reasonably related to the study
treatment by the investigator, will be reported to the Sponsor. While the investigator is not obligated to actively 
seek this information in former study participants, he or she may learn of an SAE through spontaneous 
reporting.
In addition, the investigator must attempt to collect pregnancy information on any female partners of
male study subjects who become pregnant while the subject is enrolled in the study. Pregnancy information
must be reported to NovartisGSK as described above.

change in existing therapy) or related to a GSK product will be recorded from the time a patient consents  
to participate  in the study  up to and including any follow-up contact.

Medical occurrences that begin prior to the start of protocol therapy but after obtaining informed consent
should be recorded on the Medical History/Current Medical Conditions section of the eCRF.

Any new primary cancer must be recorded as an SAE and will be recorded from the time a patient consents 
to participate in the study up to and including any follow-up contact.

All SAEs will be recorded and reported to GSK and COG within 24 hours, as indicated in Section 11.8.

Investigators are not obligated to actively seek AEs or SAEs in former study participants.

However, if the investigator learns of any SAE, including a death, at any time after a patient has been
discharged from the study, and he/she considers the event reasonably related to the study treatment or study
participation, the investigator should promptly notify GSK and COG.

Section: 12, Study Reporting and Monitoring
Original Text:
For this study, patient data will be entered into electronic case report forms (eCRFs), transmitted 
electronically to GSK or designee and combined with data provided from other sources in a validated data 
system.
Management of clinical data will be performed in accordance with applicable GSK standards and data 
cleaning procedures to ensure the integrity of the data, e.g., removing errors and inconsistencies in the data. 
Adverse events and concomitant medications terms will be coded using MedDRA (Medical Dictionary for 
Regulatory Activities) and an internal validated medication dictionary, GSKDrug. eCRFs (including queries 
and audit trails) will be retained by GSK, and copies will be sent to the investigator to m aintain as the 
investigator copy. Patient initials will not be collected or transmitted to GSK according to GSK policy.
