Added text:  Management of 
Osteonecrosis of the Jaw 
Perform an oral examination prior 
to treatment with lenvatinib and 
periodically during lenvatinib 
treatment. Advise study subjects 
regarding good oral hygiene 
practices. Avoid invasive dental 
procedures, if possible, while on 
lenvatinib treatment, particularly in 
study subjects at higher risk. For 
study subjects requiring invasive 
dental procedures, discontinuation 
of bisphosphonate treatment may 
reduce the risk of osteonecrosis of 
the jaw. Withhold lenvatinib if 
osteonecrosis of the jaw develops 
and restart based on clinical 
judgement of adequate resolution 
(see Section 9.4.7).

Study Design 
This is a multicenter, open-label, Phase 1/2 study of lenvatinib in combination with everolimus in 
pediatric subjects with relapsed or refractory solid tumors.   
Phase 1 Dose Escalation and Determination of the MTD 
The Phase 1 component is a dose escalation study with treatment in sequential cohorts of escalating 
doses of lenvatinib in combination with everolimus, each administered once daily in 28-day 
treatment cycles.  Pediatric subjects with a relapsed/refractory solid malignancy, including primary 
brain tumors are eligible to participate.  The initial dose level (Dose Level 1) for lenvatinib will be 
11 mg/m2, which is approximately 80% of lenvatinib single dose MTD in pediatric subjects 
determined in the ongoing Study E7080-G000-207.  The initial dose of everolimus will be 
3 mg/m2, which is 66% of the Food and Drug Administration (FDA) approved dose and a dose 
previously found to be effective in subependymal giant cell astrocytoma (SEGA).   
Dose Level 2 will escalate lenvatinib by approximately 25% to 14 mg/m2 and maintain everolimus 
at the same dose of 3 mg/m2.  At Dose Level -1 and 1, the maximum daily dose of lenvatinib will 
not exceed 18 mg daily.  At Dose Level 2, the maximum daily dose of lenvatinib allowed will not 
exceed 24 mg.  Should Dose Level 2 be well tolerated, Dose Level 3 may be considered to test 
lenvatinib at 14 mg/m2 (capped at 24 mg) and escalate everolimus to 4.5 mg/m2.  For everolimus 
dose levels of 3 mg/m2 and 4.5 mg/m2, the maximum daily dose of everolimus will not exceed 
5 mg and 7 mg, respectively.  If the MTD for combination of lenvatinib and everolimus has been 
exceeded at Dose Level 1, then the subsequent cohort of subjects will be treated at Dose Level -1 
with dose of lenvatinib 8 mg/m2 and dose of everolimus 3 mg/m2 (Table 1).  Intra-subject titration 
of everolimus will not be allowed on this study.  
At study entry, subjects must have a minimum body surface area (BSA) of 0.6 m2.

The study will utilize a rolling 6 design (Skolnik, et al., 2008).  Two to 6 subjects can be 
concurrently enrolled into a dose level cohort.  Dose level assignment will be based on the 
following:  
1. the number of subjects currently enrolled in the dose level cohort,  
2. the number of dose-limiting toxicities (DLTs) observed, and  
3. the number of subjects at risk for developing a DLT (ie, subjects enrolled but who are not yet 
assessable for toxicity).   
For example, when 3 subjects are enrolled onto a dose cohort, if toxicity data is available for all 3 
when the fourth subject entered and there are no DLTs, the dose is escalated and the fourth subject 
is enrolled to the subsequent dose level.  If data is not yet available for one or more of the first 
3 subjects and no DLT has been observed, or if one DLT has been observed, the new subject is 
entered at the same dose level.  Lastly, if 2 or more DLTs have been observed, the dose level is 
de-escalated.  This process is repeated for Subjects 5 and 6.  In place of suspending accrual after 
every 3 subjects, accrual is only suspended when a cohort of 6 is filled (ie, subjects enrolled but are 
not yet assessable for toxicity) or when the study endpoints have been met.  When subjects are not 
evaluable for toxicity, they will be replaced with the next available subject if escalation or 
de-escalation rules have not been fulfilled at the time the next available subject is enrolled onto the 
study. 
The following table (Table 2) provides the decision rules for enrolling a subject at (i) the current 
dose level, (ii) at an escalated dose level, (iii) at a de-escalated dose level, or whether the study is 
suspended to accrual:

myelosuppression), expansion of the cohort to 12 subjects will be considered (if one of the DLTs 
does not appear to be dose-related, the Adverse Effects are readily reversible, AND Protocol 
Steering Committee (PSC) AND sponsor all agree that expansion of the cohort is acceptable).  
Subjects who on PSC review are not deemed to be evaluable for DLT assessment may be replaced. 
All subjects in the Phase 1 Dose Escalation phase will have samples taken for PK analysis with the 
intent at the end of Phase 1 of having evaluable PK data from minimally 6 subjects aged 2 to 
<6 years old, 6 subjects ≥6 to <12 years old, and 6 subjects ≥12 years old.  Once the MTD or RP2D 
has been defined, 0 to 6 additional subjects will be enrolled to attain the goal of having evaluable 
PK data from minimally 6 subjects aged 2 to <6 years old, 6 subjects aged ≥6 to <12 years old, and 
6 subjects ≥12 years old.  
Protocol Steering Committee 
The sponsor will closely evaluate the risks and benefits of the study throughout its conduct, along 
with the PSC as needed.  The PSC may review available relevant data: DLT and safety data 
including laboratory assessments, 12-lead electrocardiograms (ECGs), dose administration, etc. 
Toxicity Monitoring 
The DLT observation period for the purposes of dose-escalation will be the first cycle of therapy.  
Routine Phase 1 monitoring for clinical and laboratory toxicities will be used.  Blood pressure (BP) 
monitoring will occur at least weekly during the first 2 cycles.   
Dose-limiting toxicity will be assessed according to Common Terminology Criteria for Adverse 
Events (CTCAE) v4.03 and is defined as any of the following events that are possibly, probably, or 
definitely attributable to lenvatinib or everolimus.  Dose-limiting hematological and 
non-hematological toxicities are defined differently. 
A. Non-hematological DLT: 
 Any Grade 3 or greater non-hematological toxicity attributable to the investigational drug 
with the specific exclusion of: 
o Grade 3 nausea and vomiting <3 days duration 
o Grade 3 diarrhea <3 days duration 
o Grade 3 weight loss 
o Grade 3 liver enzyme elevation, including alanine aminotransferase/aspartate 
aminotransferase(ALT/AST)/ gamma glutamyl transferase (GGT)/ bilirubin/alkaline 
phosphatase that returns to Grade 1 or baseline within 7 days 
o Grade 3 asymptomatic elevation in amylase or lipase that returns to Grade 1 or 
baseline within 7 days 
o Grade 3 elevation in triglycerides that returns to Grade 1 or baseline within 7 days 
o Grade 3 or 4 fever <5 days duration 
o Grade 3 infection <5 days duration 
o Grade 3 hypophosphatemia, hypokalemia, hypocalcemia or hypomagnesemia 
responsive to oral supplementation 
o Grade 3 proteinuria (urine protein:creatinine [UPC]) ratio >1.9 unless confirmed with a 
second measurement within 72 hours 
o Grade 3 headache <3 days duration responsive to optimal management 
 Any Grade 2 non-hematological toxicity that persists for ≥7 days and is considered 
sufficiently medically significant or sufficiently intolerable by subjects despite optimal 
supportive care that it requires treatment interruption. 
 Any dose interruption or reduction due to toxicity which results in administration of less 
than 75% of the planned dosage of lenvatinib and/or everolimus. 
 Note:  Allergic reactions that necessitate discontinuation of study drug will not be 
considered a DLT.

 Dose-limiting hypertension: 
o Any Grade 4 hypertension  
o Confirmed systolic or diastolic BP more than 25 mmHg above 95th percentile for sex, 
age, height/length, or an elevated diastolic BP (ie, >95th percentile for age) not 
controlled by a single antihypertensive medication within 14 days of use.  An 
antihypertensive tablet or capsule that contains up to 2 antihypertensive ingredient 
medications will be considered a single antihypertensive medication. 
B. Hematological DLT:    
 In subjects evaluable for hematological toxicity, DLT is defined as: 
o Grade 4 thrombocytopenia (platelet count <25,000/mm3) or Grade 4 neutropenia, not 
due to malignant infiltration. 
 Any ≥Grade 2 arterial thromboembolic events (including cerebrovascular ischemia, 
peripheral or visceral arterial ischemia). 
 Note:  Grade 3 or 4 febrile neutropenia will not be considered a DLT. 
All DLTs must be reported to the sponsor within 24 hours of their occurrence.  Determination of a 
DLT will be made by the investigator and the Eisai Medical Monitor in consultation with the PSC, 
as needed.  Subjects who discontinue the study treatment for any reason other than DLT (eg, early 
disease progression) during Cycle 1 (Day 1 to Day 28) and have not received at least 75% of the 
prescribed dose prior to discontinuation will be replaced. 
The sponsor and PSC will review all subjects’ safety and clinical data to jointly determine the 
MTD/RP2D of the combination of lenvatinib with everolimus. 
The Treatment Phase for each subject in Phase 1 ends after completing Cycle 1 of treatment unless 
subject discontinues early.  Those subjects who discontinue study treatment in Cycle 1 transition to 
the Off-treatment Visit.  Those who complete Cycle 1 will transition to the Extension Phase.  Study 
treatment and tumor assessments will continue during the Extension Phase. 
Phase 2 Cohorts 
Once the MTD/RP2D of the combination of lenvatinib and everolimus in pediatric population has 
been determined in Phase 1, the Phase 2 portion of this pediatric study will commence with 
Cohort 1 (recurrent or refractory Ewing sarcoma/pPNET), Cohort 2 (recurrent or refractory 
rhabdomyosarcoma), and Cohort 3 (recurrent or refractory HGG), opening to accrual. 
Cohorts 1 – 3  
Phase 2 Cohorts 1-3 will use a 10+10 Simon’s optimal 2-stage design for each cohort; 10 evaluable 
subjects will be enrolled to each stage.  The Sponsor will closely monitor enrollment to ensure that 
at least 50% of subjects enrolled in each cohort are <18 years of age at the time of informed 
consent.  The primary outcome measure for Ewing sarcoma/pPNET, rhabdomyosarcoma, and 
HGG will be ORR (complete or partial response) at 16 weeks.  If there are no responses among the 
10 subjects in Stage 1, then the enrollment to that disease cohort will stop and it will be concluded 
that the lenvatinib/everolimus combination therapy did not elicit a response in that disease cohort.  
If there is at least 1 response in the first stage, then the second stage will enroll 10 additional 
evaluable subjects.  If there are 2 or fewer responses among the 20 evaluable subjects, then 
lenvatinib/everolimus combination therapy will be declared a failure for that disease cohort. 
Subjects will meet the criteria for being evaluable for an objective response, if they have 
measurable disease present at baseline and at least 1 post-baseline efficacy assessment, unless they 
have discontinued prior to the first efficacy assessment due to progressive disease. Subjects who 
are not evaluable for objective response will be replaced.

The Treatment Phase for each subject in Phase 2 ends after completing 4 cycles of treatment unless 
the subject discontinues early.  Those who discontinue study treatment before completing 4 cycles 
transition to the Off-treatment Visit.  Those who complete 4 cycles transition to the Extension 
Phase.  Study treatment and tumor assessments will continue during the Extension Phase. 
Dosing Nomogram  
The dose nomogram in Table 3 provides dose of lenvatinib to be administered for BSA increments 
starting from 0.6 m2.  BSA must be calculated on Day 1 of each cycle based on the subject’s 
current height and body weight.  The actual dose to be administered is rounded to the nearest whole 
number. The total lenvatinib dose is capped at 18 mg daily (Dose Levels -1 and 1), and at 24 mg 
daily (Dose Levels 2 and 3).

are expanded to 12 subjects and 6 additional subjects need to be enrolled in the PK Cohort, a 
maximum of 54 subjects (allowing for 20% to be non-evaluable and including the additional 
6 subjects for PK analysis) will be enrolled. 
• 
Phase 2 Cohorts 1 - 3:  10 to 20 evaluable subjects per cohort (maximum 22 subjects enrolled 
per cohort allowing for 10% to be non-evaluable).  A maximum of 66 subjects will be enrolled 
in Phase 2.  In each cohort, at least 50% of the subjects enrolled will be <18 years old at the 
time of informed consent.

Lenvatinib and everolimus will be administered orally on a once daily schedule in continuous 
28-day cycles.  The sequence of administration is not important.  Dosing nomograms based on 
BSA and dose level will be used to prescribe lenvatinib and everolimus for subjects to minimize 
inter-subject dosing variability.  The maximum daily dose of lenvatinib administered during the 
study should not exceed 18 mg in Dose Levels -1, and 1, and 24 mg in Dose Levels 2 and 3.  The 
maximum daily dose of everolimus should not exceed 5 mg in Dose Levels -1, 1, and 2, and 7 mg 
in Dose Level 3.  Intra-subject titration of everolimus will not be allowed on this study.  Intra-
subject dose escalation will not be allowed. 
Comparator Drug (if applicable):  Not Applicable 
Study Drug Dose Interruption and Reduction Instructions: 
Dose reductions and interruptions for subjects who experience lenvatinib-everolimus combination 
therapy-related toxicity will be managed as described in Table 5.  Investigators will decide the 
probability of the event being related to protocol therapy as to whether dose modification of drug 
therapy is required. 
Asymptomatic laboratory abnormalities, including Grade ≥3 abnormalities (eg, elevations of 
amylase and lipase) that are not considered clinically relevant by the investigator, should be 
managed per institutional guidelines; continuation of treatment should be discussed with the 
sponsor. 
Doses in the Dose Adjustment column are based on a presumed starting dose of 11 mg/m2 
lenvatinib and 3 mg/m2 everolimus.  Dose reductions will occur in succession based on the 
previous dose level.  Each dose level reduction due to toxicity at a given BSA is approximately 
25% reduction from the previous dose.  Once the study drug dose has been reduced, it may not 
be increased at a later date, unless the dose was mistakenly decreased; in this situation, the 
sponsor’s approval is required to increase the dose.

Note: For grading see Common Terminology Criteria for Adverse Events (CTCAE) v4.03.  Collect all CTC 
grades of adverse events, decreasing and increasing grade.  
a: An interruption of study treatment for more than 28 days will require sponsor`s approval before treatment can 
be resumed.  
b: Initiate optimal medical management for nausea, vomiting, hypothyroidism and/or diarrhea prior to any study 
treatment interruption or dose reduction.  
c: Applicable only to Grade 2 toxicities judged by the subject and/or physician to be intolerable. 
d: Obese subjects with weight loss do not need to return to the baseline weight or within10% of baseline weight 
(ie, Grade 1weight loss).  These subjects will restart the study drug(s) at a lower dose once their weight remains 
stable for at least 1 week and they reached the normal body mass index (BMI; if the weight loss occurred, but it 
is still above normal BMI, they can restart the study treatment at a lower dose once the weight has been stable 
for at least 1 week).  Normal BMI should be used as the new baseline for further dose reductions.  
e: For Grade 2 toxicity, resume everolimus at the same dose as prior to dose interruption.  For Grade 3 toxicity, 
investigator will decide the probability of the event being related to one or both drugs as to whether dose 
modification of one or both drugs is required. 
f: For asymptomatic laboratory abnormalities, such as Grade ≥3 elevations of amylase and lipase that are not 
considered clinically relevant by the investigator, continuation of treatment should be discussed with the 
sponsor. 
g: Excluding laboratory abnormalities judged to be non-life-threatening, in which case manage as Grade 3. 
 
 
Duration of Treatment 
Study duration for each subject is estimated to be: 
 
Pretreatment Phase:  4 weeks 
 
Treatment Phase:  1 cycle (4 weeks) in Phase 1, 4 cycles (16 weeks) in Phase 2. 
 
Extension Phase: Estimated maximum time of treatment is 2 years (24 cycles)  
Subjects may remain on study treatment as long as they do not meet any of the following criteria: 
1) experience objective progression of disease (according to RECIST 1.1 or RANO criteria, as 
appropriate); 2) exhibit no clinical benefit (in the opinion of the investigator); 3) experience 
unacceptable toxicity leading to withdrawal from the study; 4) withdraw or are withdrawn from the 
study for any reason, or; 5) termination of the study program.  
As long as the subject has not experienced intolerable toxicity, he or she can continue to receive 
study treatment.  A 28-day follow-up visit from last date of receiving investigational drug will be 
performed for subjects who discontinue study treatment.

Treatment (including blood products, blood transfusions, fluid transfusions, antibiotics, and 
antidiarrheal drugs, etc.) of complications of AEs or therapy to ameliorate symptoms may be 
administered at the discretion of the investigator, unless it is expected to interfere with the 
evaluation of (or to interact with) the study medication.  
An anti-diarrheal agent should be recommended to the subject at the start of study treatment and 
subjects should be instructed and educated to initiate anti-diarrheal treatment at the first onset of 
soft bowel movements.  The choice of anti-diarrheal agent should be individualized to the subject’s 
clinical circumstances and follow standard medical practice.  If signs/symptoms of diarrhea persist 
despite optimal medical management, instructions contained in the Dose Modification Guidelines 
should be followed. 
Administration of corticosteroids for progressive disease is not permitted.  Administration of 
corticosteroids will be limited to premedication or the short-term treatment of acute medical 
conditions in accordance with approved indications, institutional, or national guidelines. 
Further information on the prohibited concomitant therapies for lenvatinib and everolimus is 
included in the respective package inserts. 
Assessments 
Tumor Assessments:  
For all tumor types except HGG:  Tumor assessments will be performed using RECIST 1.1.  
Investigator-determined response assessments will be performed at each assessment time point and 
entered onto case report form.  Tumor assessments (CT chest and CT/MRI of abdomen, pelvis and 
other areas of known disease at screening plus any areas of suspected disease) should be performed 
at Screening and, for Phase 1 of the study, at Week 4 ±1 week, Week 12 ±1 week, Week 24 
±1 week and every12 weeks ±1 week thereafter, or as clinically indicated.  For subjects with 
primary CNS tumors and no other known areas of disease only CNS target and non-target lesions 
plus any areas of newly suspected disease must be scanned.  For Phase 2 of the study, tumor 
assessments should be performed at Screening, Week 8 ±1 week, Week 16 ±1 week, Week 24 ±1 
week, and then every 12 weeks ±1 week thereafter, or as clinically indicated.  All responses are to 
be confirmed at a follow-up examination after ≥28 days following the initial indication of response. 
A brain scan (CT with contrast or MRI pre-and post-contrast) will be performed at Screening, and 
during the study if clinically indicated.  
For HGG:  Tumor assessments will be performed using RANO Criteria.  A standard MRI imaging 
protocol will be performed for use in the assessments.  Investigator-determined response 
assessments at each assessment time point will be entered onto the appropriate CRFs.  Tumor 
assessments will be carried out during Screening and for Phase 1 of the study, at Week 4 ±1 week, 
Week 12 ±1 week, Week 24 ±1 week, and then every 12 weeks ±1 week thereafter, or as clinically 
indicated.  For Phase 2 of the study, tumor assessments should be performed at Screening, Week 8 
±1 week, Week 16 ±1 week, Week 24 ±1 week, and every 12 weeks ±1 week thereafter, or as 
clinically indicated.  
For Phase 2, copies of scans for tumor assessments will be sent to an imaging core laboratory 
designated by the sponsor for quality assessment and archival and potential future independent 
review. 
The imaging methodology for tumor assessments for all tumor types, including solid tumors and 
HGG, will be provided in an appendix to the study protocol. 
Pharmacokinetic Assessments:  Blood samples for plasma concentrations of lenvatinib and whole 
blood concentrations of everolimus will be collected from all subjects as described in the Schedule 
of Assessments. 
Pharmacodynamic (PD) Assessments:  Blood samples for plasma and serum studies will be 
collected from consenting subjects (optional) at Baseline and on Cycle 1 Day 15, Cycle 2 Day 1,

and then matched with tumor assessments and at the Off-treatment Visit, as specified in the 
Schedule of Assessments.  Only subjects with BSA >0.68 m2 are eligible to consent (optional) to 
blood samples for plasma and serum studies.  Biomarker discovery and/or validation will be 
performed to identify blood or tumor biomarkers that may be useful to predict subject response to 
study drug as well as for potential use in diagnostic development.  Blood samples may undergo 
global proteomic and/or single analyte enzyme-linked immunosorbent assays (ELISA) or multiplex 
immunoassays based on the amount of sample available.  Potential blood biomarkers to be 
explored include, FGF ligands (eg, FGF2/bFGF, FGF19, FGF21, FGF23), and angiogenesis related 
markers (eg, VEGF, Ang 1/2, sTie-2, HGF, PlGF).  In addition, biomarkers identified in other 
lenvatinib clinical studies may also be assessed in samples collected from subjects enrolled in this 
study.  The decision to perform exploratory biomarker analysis may be based on the clinical 
outcome of this study and/or the signals observed in other clinical studies or other information 
available at that time. 
Pharmocokinetic/Pharmacodynamic Assessments:  Relationships between lenvatinib exposure 
and safety will be explored graphically.  Pending the outcome of graphical assessments, modeling 
of potential relationships will be explored.  Details of exposure-safety analyses will be provided in 
a separate analysis plan. 
Pharmacogenomic/Pharmacogenetic Assessments:  Archived, fixed tumor tissue will be 
collected (if available) for potential assessment of mutations and other genetic alterations in genes 
and/or proteins that may be important in the development and progression of tumor biology 
relevant to the tumor types being explored, to evaluate response to study drug treatment as well as 
for potential use in diagnostic development.  Genetic alterations in target genes include lenvatinib 
targets (eg, FGF ligands and FGF receptors 1 to 4), angiogenesis-relevant targets (such as 
expression levels of VEGF, Ang 1/2, Tie-2, HGF and cMET) and markers associated with cell 
differentiation and tumorigenesis (eg, WNT/β-catenin pathway, hedgehog/PTCH pathway, and 
BMP/TGF signaling pathway).  Appropriate analytical technology/methodologies, such as next 
generation sequencing (NGS)-based whole exome sequencing (WES), whole transcriptome 
analysis or targeted re-sequencing using targeted gene panels (eg, ThermoFisher Oncomine 
Comprehensive Assay (OCA)) for gene alterations, targeted gene expression panels (eg, 
Nanostring PanCancer Pathway, PanCancer Immune) for gene expression analysis, single analyte 
or multiplex IHC, etc may be used based on the amount of tumor tissue available. 
Blood plasma samples will be collected (optional) for analysis of cell free nucleic acid (cf-nucleic 
acid).  Cell free nucleic acid isolated from plasma samples may be used to explore tumor genetic 
alterations such as mutations and other genetic alterations observed in archival tumor samples 
(using NGS-based targeted gene panels), as well as those which develop during drug treatment to 
monitor response to study drug.   
A blood sample will be collected for pharmacogenomic (PG) analysis (optional).  Variation in 
study drug exposure or the occurrence of AEs observed in the study population may be evaluated 
by correlating single–nucleotide polymorphisms with PK, safety, or PD data.  Genomic DNA 
extracted from blood samples may be used to confirm whether the DNA sequence variants 
observed in DNA extracted from tumor material are limited to the tumor. 
Data obtained will be used for research to assist in developing safer and more effective treatments 
and will not be used to change the diagnosis of the subject or alter the therapy of the subject.  The 
PD and PG samples will not be used to determine or predict risks for diseases that an individual 
subject does not currently have.  Any sample or derivatives (DNA, RNA, and protein) may be 
stored for up to 15 years after study completion to assist in research scientific questions related to 
cancer biology or for potential diagnostic development.

Instructions for the processing, storage, and shipping of samples will be provided in the Laboratory 
Instruction Manual. 
Safety Assessments:  Routine Phase 1 monitoring for clinical and laboratory toxicities will be 
used.  CTCAE v 4.03 will be used for grading toxicities and recording of all AEs and serious 
adverse events (SAEs).  Regular performance of physical examinations, laboratory evaluation for 
hematology, blood chemistry, and urine dipstick values, periodic measurement of vital signs, 
12-lead ECGs, echocardiography/MUGA scan, Lansky play score and Karnofsky performance 
score, baseline and periodic assessments of pancreatic enzymes, thyroid-stimulating hormone 
(TSH) levels and physeal dysplasia will be performed.  BP monitoring will occur at least weekly 
during the first 2 cycles.  BP will be assessed in terms of percentile for sex, age and height/length.  
Antihypertensive agents should be started as soon as elevated BP (systolic BP ≥95th percentile [BP 
≥140 mmHg for adult subjects] or diastolic BP ≥95th percentile [BP ≥90 mmHg for adult 
subjects]) is confirmed on 2 assessments obtained 1 hour apart.  For subjects with hypertension and 
proteinuria, treatment with an angiotensin-converting enzyme (ACE) inhibitor or angiotensin-II 
receptor antagonist is preferred.  Cardiac systolic function and corrected QT interval (QTc) will be 
assessed at screening, prior to Cycles 2 and 5, and every sixth cycle thereafter by 
echocardiography/MUGA scan and ECG.  
Other Assessments 
Pregnancy Test:  A serum β-hCG test will be performed for females of childbearing potential (see 
definition included in the Inclusion/Exclusion criteria).  A serum or urine pregnancy test will be 
performed at Screening and Baseline (or within 72 hours prior to the first dose of study 
medication), prior to Day 1 of each subsequent cycle and at the Off-treatment Visit in females of 
childbearing potential.  The results must be reviewed prior to administration of study drug on Cycle 
1 Day 1 and within 48 hours prior to dispensing study drug for all subsequent cycles. Blood and 
urine samples will be taken at designated time points as specified in the Schedule of Assessments. 
 
Bioanalytical Methods 
Lenvatinib in plasma and everolimus in whole blood will be quantified using validated liquid 
chromatography tandem mass spectrometry (LC-MS/MS) methods.

Definitions of Analysis Sets 
 
Evaluable Analysis Set, defined as all subjects, who have measurable disease present at 
baseline and at least 1 post-baseline efficacy assessment, unless they have discontinued prior to 
the first efficacy assessment due to progressive disease.  This will be the analysis set for 
efficacy. 
 
Safety Analysis Set, defined as all subjects who received at least 1 dose of the study drug 
(lenvatinib or everolimus).  
 
Pharmacokinetic (PK) Analysis Set, defined as subjects in Safety Analysis Set who had at 
least 1 measurable postdose plasma concentration with an adequately documented dosing 
history. 
 
Pharmacodynamic (PD) Analysis Set, defined as all subjects in Safety Analysis Set who had 
evaluable PD data. 
Statistical Analysis 
Descriptive statistics will be used to summarize study endpoints.  Categorical variables will be 
summarized by number and percentage.  Continuous variables will be summarized using n (number 
of subjects with available data), mean, standard deviation, median, Q1, Q3, and range (minimum 
and maximum), unless otherwise specified.  
Efficacy data will be analyzed using the Evaluable Analysis Set, safety data will be analyzed using 
the Safety Analysis Set, PK data will be analyzed using the PK Analysis Set, and PD data will be 
analyzed using the PD Analysis Set.  All analyses will be performed by dose level in Phase 1 (if 
appropriate) and for each study cohort in Phase 2, unless otherwise specified.  
Efficacy Analyses 
Data cut-off for the primary study analysis in Phase 2 will occur when all subjects have completed 
at least 4 treatment cycles and, if applicable, a confirmatory scan has been performed (in case of a 
PR or CR at Week 16), or have discontinued study drug early. 
The following are evaluability criteria for objective response and non-target disease response 
analysis: 
 
Evaluable for objective response: Only those subjects who have measurable disease present 
at baseline and have their disease re-evaluated at post-baseline visits will be considered 
evaluable for objective response.  These subjects will have their response classified according 
to RECISIT 1.1 (for Ewing sarcoma/pPNET and rhabdomyosarcoma) or RANO (for HGG).   
 
Evaluable for non-target disease response:  Subjects who have lesions present at baseline 
that are evaluable but do not meet the definitions of measurable disease and have had their 
disease re-evaluated at post-baseline visits will be considered evaluable for non-target disease.  
Subjects with only non-target disease will be summarized by their best overall response.  The 
response will be classified according to RECIST 1.1 defined categories for subjects with non-
target disease only.

Primary Efficacy Analysis 
Phase 1: 
The study will utilize the rolling 6 design.  The primary objective of Phase 1 is to determine the 
MTD and to establish the RP2D.   
Phase 2:  
The primary efficacy endpoint in Phase 2 is ORR at 16 weeks.  Objective responses will count only 
confirmed CR and PR.  Estimated ORR and its exact 95% confidence interval (CI) using the 
method of Clopper and Pearson will be presented.   
Secondary Efficacy Analyses for Phase 1 and Phase 2 
The secondary efficacy endpoints will be ORR at the time of data cutoff, DCR, CBR and DOR.  
These endpoints in Phase 1 will be summarized if appropriate and listed by dose level, and ORR 
will be based only on subjects with measureable disease at screening/baseline.  For Phase 2, the 
ORR, DCR and CBR will be provided with exact 95% CIs using the method of Clopper and 
Pearson, and the DOR will be analyzed for responders using Kaplan-Meier approach. 
Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker Analyses 
Pharmacokinetic Analysis 
Lenvatinib and everolimus concentration versus time data will be tabulated and summarized and 
graphically presented.   
Plasma concentrations of lenvatinib from the intense sampling in Phase 1 will be used to determine 
the following PK parameters: area under the plasma concentration time course profile (AUC), 
maximum observed concentration (Cmax), and time from dosing to the maximum observed 
concentration (Tmax).  Other PK parameters may be determined as data permit. 
For both lenvatinib and everolimus, data from both Phase 1 and 2 of the study will be pooled with 
available data from other studies and subjected to population PK analysis.  For each drug, the PK 
model will be parameterized in terms of clearance and volume of distribution.  Details of the 
population PK analysis will be provided in a separate analysis plan. 
Pharmacodynamic, Pharmacokinetic/Pharmacodynamic, Pharmacogenomic, and Other 
Biomarker Analyses 
Correlation between clinical response to treatment associated with a combination of lenvatinib and 
everolimus and blood or tumor biomarkers will be examined using descriptive statistics and 
graphic displays as appropriate.  Details will be provided in a separate analysis plan. 
Pharmacokinetic/PD exposure-safety relationships will be explored.  Safety endpoints will be most 
frequent AEs of special interest and dose reductions. Exploratory/graphical analyses will be 
conducted for PK/PD evaluations, and may be followed by model-based analyses.  A detailed 
analysis plan will be provided separately. 
Safety Analyses 
A descriptive summary of all toxicities will be provided. 
The following are evaluability criteria for toxicity analysis: 
 
Evaluable for toxicity:  All subjects who received at least 1 dose of study treatment are 
evaluable for toxicity.  For Phase 1, toxicities during Cycle 1 will be used for the purpose of 
dose escalations according to the rolling 6 design.  Subjects who developed a DLT or received 
at least 75% of the prescribed dose during Cycle 1 are considered fully evaluable for toxicity 
for the purpose of dose escalation. 
The incidence of treatment-emergent adverse events (TEAEs) and SAEs will be summarized by 
system organ class and preferred term.  Laboratory test data, vital signs, 12-lead ECGs, cardiac 
function by echocardiography/MUGA scan, urine dipstick, and Lansky play scores or Karnofsky

performance scores, and their changes or shifts from baseline will be summarized using descriptive 
statistics, as appropriate.  Summary of study drug exposure will be provided.  Prior and 
concomitant medications, medical/surgical history and subject demographics will be summarized.  
Interim Analyses 
For each disease cohort (Ewing sarcoma/pPNET, rhabdomyosarcoma, and HGG) in Phase 2, there 
will be 1 futility analysis:  this is planned for after the first 10 evaluable subjects have completed 
the Week 16 tumor assessment (or discontinued before Week 16).  At the futility analysis, if there 
are no responders (CR/PR), then the enrollment for that cohort will be discontinued for lack of 
efficacy.  If 1 or more responses are observed, the accrual will continue. 
Independent data monitoring committee (IDMC) 
Safety monitoring will be conducted by an independent data monitoring committee (IDMC). The 
frequency of safety reviews will be defined in the IDMC charter. Minutes from the open meetings 
of the IDMC will be provided if requested by regulatory agencies. The function and membership of 
the IDMC will be described in the IDMC charter. 
Sample Size Rationale 
Phase 1 – Determination of the Maximum Tolerated Dose:  The total number of subjects 
required for the Phase 1 portion of this study will depend upon the toxicities observed as the study 
progresses.  The minimum number of evaluable subjects required is 4.  The projected maximum 
number of evaluable subjects required is 48.  Once the MTD or RP2D has been defined, up to 6 
additional subjects with recurrent or refractory solid tumors may be enrolled to acquire PK data in 
a representative number of young subjects.  Therefore, a maximum of 54 subjects are expected to 
be enrolled in the 4 dose escalation levels, and PK expansion.  The Phase 1 part of the study is 
expected to be completed within 18 months.  In the event that each of Dose Levels -1, 1, 2, and 3 
are expanded to 12 subjects, an absolute maximum of 54 subjects would be required allowing for 
20% to be non-evaluable and including up to 6 additional subjects for PK analysis. 
Phase 2:  Phase 2 will require a minimum of 10 evaluable subjects per disease cohort and a 
maximum of 20 (10 evaluable subjects in each stage of Simon’s optimal 2-stage design).  
Therefore, a maximum of 22 subjects per cohort will be enrolled to allow for a 10% non-evaluable 
rate.  This design has 88% power to detect a 20% increase in the response rate at the significance 
level of one-sided alpha = 0.07 assuming a null response rate of 5% and alternative response rate 
≥25%.

ETHICS 
5.1 
Institutional Review Boards/Independent Ethics Committees 
The protocol, informed consent form (ICF)/assent, and appropriate related documents must 
be reviewed and approved by an Institutional Review Board (IRB) or Independent Ethics 
Committee (IEC) constituted and functioning in accordance with International Council for 
Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) E6 
Good Clinical Practice (GCP), Section 3, and any local regulations (eg, Code of Federal 
Regulations, Title 21 CFR Part 56 or European Union [EU] Clinical Trials Directive 
2001/20/EC).  Any protocol amendment or revision to the ICF will be resubmitted to the 
IRB/IEC for review and approval, except for changes involving only logistical or 
administrative aspects of the study (eg, change in clinical research associate(s) [CRA(s)], 
change of telephone number[s]).  Documentation of IRB/IEC compliance with the ICH E6 
and any local regulations regarding constitution and review conduct will be provided to the 
sponsor. 
A signed letter of study approval from the IRB/IEC chairman must be sent to the principal 
investigator with a copy to the sponsor before study start and the release of any study drug to 
the site by the sponsor or its designee (ICH E6, Section 4.4).  If the IRB/IEC decides to 
suspend or terminate the study, the investigator will immediately send the notice of study 
suspension or termination by the IRB/IEC to the sponsor. 
Study progress is to be reported to IRB/IECs annually (or as required) by the investigator or 
sponsor, depending on local regulatory obligations.  If the investigator is required to report to 
the IRB/IEC, he/she will forward a copy to the sponsor at the time of each periodic report.  
The investigator(s) or the sponsor will submit, depending on local regulations, periodic 
reports and inform the IRB/IEC of any reportable adverse events (AEs) per ICH guidelines 
and local IRB/IEC standards of practice.  Upon completion of the study, the investigator will 
provide the IRB/IEC with a brief report of the outcome of the study, if required. 
At the end of the study, the sponsor should notify the IRB/IEC and Competent Authority 
within 90 days.  The definition for end of the study is the date of data cutoff for the final 
analysis or last subject/last visit including discontinuation from the study for any reason, 
whichever occurs later.  Subjects who remain on treatment at the cutoff for the final analysis 
will continue receiving the same treatment in consecutive cycles as long as they do not meet 
any of the study discontinuation criteria as detailed in the protocol. 
In the case of early termination/temporary halt of the study, the investigator should notify the 
IRB/IEC and Competent Authority within 15 calendar days, and a detailed written 
explanation of the reasons for the termination/halt should be given.

INTRODUCTION 
Solid tumors make up about 30% of all cancers in children.  Current strategies for treatment 
of solid tumors in children have greatly improved in the last few decades.  The success of 
curing nearly 80% of children diagnosed with cancer is tempered by the inability to cure the 
remaining 20% with conventional approaches.  There remains a significant unmet medical

need for more effective treatment options with a manageable safety profile and for 
identifying biomarkers to more accurately diagnose these tumors and determine the level of 
risk in pediatric patients with solid tumors. 
Some of the most common types of solid tumors found in children are brain tumors, 
rhabdomyosarcoma, and Ewing sarcoma/peripheral primitive neuroectodermal tumor 
(pPNET).  
High grade gliomas (HGGs) represent approximately 8–12% of all pediatric central nervous 
system (CNS) tumors.  The overall total incidence of HGG (including anaplastic 
astrocytoma, anaplastic oligodendrioglioma, glioblastoma, mixed glioma, and malignant 
glioma) among children 0-19 years old is approximately 0.85 per 100,000 (CBTRUS 2012).  
The distribution of HGGs between males and females is relatively equal (Finlay, et al., 
2005).  Pediatric HGGs are very aggressive and malignant lesions.  Initial treatment 
strategies typically consist of a gross total resection when feasible followed by focal 
radiotherapy combined with chemotherapy.  Despite improvements in neurosurgery, 
radiotherapy, and chemotherapy, the outcome for children with HGG remains poor.  No 
effective chemotherapy regimens have been identified for any pediatric HGG 
(MacDonald, et al., 2011).  Two-year survival rates range from 10% to 30%.  
Rhabdomyosarcoma is the most common soft tissue sarcoma in children, with approximately 
350 new cases diagnosed each year in the US among the population age group between 0 and 
19 years (Linet, et al., 1999).  There is slight male predominance, and approximately 
two-thirds of the cases are diagnosed in children younger than 6 years of age 
(Dasgupta, et al., 2012).  Rhabdomyosarcoma usually manifests as an expanding mass in 
different body locations.  The most common primary tumor sites include the head and neck 
region (35%), followed by the genitourinary and extremity primaries (Pappo, et al., 1995).  In 
patients with localized disease, overall 5-year survival rates are over 80% with the combined 
use of surgery, radiation therapy, and 3-drug chemotherapy of vincristine, actinomycin D, 
and cyclophosphamide (VAC).  However, in patients with metastatic disease, little progress 
has been made in survival rates, with a 5-year, failure-free survival rate of less than 30% 
(Egas-Bejar, et al., 2014). 
Ewing’s sarcoma/pPNET also called Ewing’s sarcoma family of tumors (ESFT) constitutes 
5% to 10% of primary bone tumors (Gurney, et al., 1999).  It occurs predominantly in 
children and young adults and shows a slight predominance for males.  Ewing’s 
sarcoma/pPNET is very rare with an incidence of just less than 3 per 1 million people under 
20 years of age (Esiashvili, et al., 2008).  It occurs most frequently in the pelvis, long bones 
of the legs or arms, chest wall, spine and the skull.  The first line treatment consists of 
neoadjuvant chemotherapy followed by local control surgery (which frequently involves 
limb-sparing surgery with prosthetic reconstruction) with or without radiation, followed by 
adjuvant chemotherapy.  Chemotherapy involves a 5-drug regimen of vincristine, 
doxorubicin, cyclophosphamide alternating with ifosfamide and etoposide in 2-3 weeks 
intervals (VDC-IE).  Presence of metastases is the most prominent adverse prognostic factor 
in Ewing’s sarcoma/pPNET.  Metastases at diagnosis are detected in 15% to 33% of patients,

with survival rates from 9% to 41%, as compared with the survival expectancy of patients 
with localized disease of approximately 70% (Ladenstein, et al., 2010). 
7.1 
Scientific Rationale for the Combination of Lenvatinib with 
Everolimus 
Angiogenesis is vital for the growth and metastatic behavior of malignant solid tumors.  
Vascular endothelial growth factor (VEGF) is critical to both physiologic and pathologic 
angiogenesis, and ligand-binding to VEGF receptor (VEGFR1-3) has been shown to drive 
tumor growth and facilitate metastasis (Ferrara, et al., 2002).  VEGFR-predominating 
receptor tyrosine kinase inhibitors (RTKIs) have emerged as successful anticancer agents, 
with numerous Food and Drug Administration (FDA) approved drugs in class, and several 
indications for renal and hepatic carcinomas, thyroid cancer and soft tissue sarcoma (Brose, 
et al., 2014; van der Graaf, et al., 2012; Llovet, et al., 2008; Escudier, et al, 2007; Motzer, et 
al., 2007).  RTKIs have consistently demonstrated anti-tumor activity in preclinical models 
of pediatric solid tumors, notably rhabdomyosarcoma, Ewing sarcoma, and neuroblastoma 
models (Maris, (a) et al., 2008; Maris, (b) et al., 2008).  Factors limiting the clinical efficacy 
of RTKIs in pediatric tumors to date may include the early acquisition of drug resistance, 
tumor heterogeneity, and utilization of alternative survival pathways in tumors.  Classic 
resistance to RTKIs include secondary mutations that disrupt target binding, increased RTK 
expression, increased ligand expression, increased drug efflux, and altered drug metabolism 
pathways (Engelman, et al., 2008), and altered energy (glucose) metabolism (Hudson, et al., 
2014).   
Lenvatinib is a potent multiple RTKI that selectively inhibits VEGFRs (VEGFR1 [FLT1], 
VEGFR2 [KDR], VEGFR3 [FLT4]) in addition to other pro-angiogenic and oncogenic 
pathway-related RTKs, including fibroblast growth factor (FGF) receptors FGFR1-4, 
platelet-derived growth factor (PDGF) receptor α, KIT, and RET.  Lenvatinib has potent 
anti-angiogenic properties not only towards VEGF-driven angiogenesis and 
lymphangiogenesis but also towards FGF-driven angiogenesis.  Through established VEGF- 
and FGF-dependent angiogenesis mouse models, lenvatinib significantly inhibited both 
VEGF- and FGF-induced in vivo angiogenesis in a dorsal air sac assay at doses of 10 and 
30 mg/kg (Ichikawa, et al., 2015; Yamamoto, et al., 2014).  A subset of glioblastomas harbor 
oncogenic chromosomal translocations involving the in-frame fusion of the tyrosine kinase 
domains of FGFR1 or FGFR3 with TACC genes which result in constitutive kinase activity 
(Parker, et al., 2013; Singh, et al., 2012).  Treatment of in vivo models harboring the 
FGFR-TACC fusions with an FGFR inhibitor prolongs survival suggesting a role for 
FGFR-targeted therapies in high grade CNS tumors.  The studies also demonstrated 
activating recurrent hotspot mutations and intragenic duplications of the tyrosine kinase 
domain of FGFR1 in pediatric pilocytic astrocytomas and diffuse pediatric gliomas 
respectively providing further rationale for exploring agents targeting FGFR (Zhang, 
et al., 2013; Jones, et al., 2013).  
In addition to the anti-proliferative activity of lenvatinib, target engagement of the FGFR 
signaling pathway has been evaluated in both in vitro and in vivo models (Tohyama, 
et al., 2014).  Lenvatinib treatment at doses as low as 3 mg/kg and 10 mg/kg demonstrated a

decrease in phosphorylation of FRS2 levels in the RO82-W-1 xenograft model 
(Tohyama, et al., 2014).  These results demonstrate that lenvatinib effectively engages and 
inhibits the FGFR signaling pathway in vitro and in vivo which contributes to the observed 
anti-tumor activity of lenvatinib.  Further in vitro and in vivo studies confirm the inhibition 
of FGFR1 and downstream targets including MEK and Erk (Nakazawa, et al., 2015). 
FGF ligand levels, such as FGF23, may be useful biomarkers for FGFR inhibition by 
lenvatinib (Ichikawa, et al., 2015).  FGF23, a protein hormone regulating mineral 
metabolism, is a potential pharmacodynamics (PD) marker for FGFR inhibition in vivo, since 
plasma levels are elevated as a compensatory response to FGFR inhibition 
(Wohrle, et al., 2011; Kim, et al., 2011).  Plasma FGF23, was significantly increased 
(2.6-fold, compared to vehicle control) in mice 24 hours after a single oral administration of 
lenvatinib mesylate (10 mg/kg) (Ichikawa, et al., 2015).  Inhibition of multiple receptors is 
also postulated as a mechanism to decrease the rate of drug resistance to anti-angiogenic 
therapy (Sonpavde, et al., 2012).  
Lenvatinib showed a favorable profile for combination in preclinical studies on 5 human 
osteosarcoma tumor xenograft models demonstrating that lenvatinib enhances the anti-tumor 
activity of conventional cytotoxic chemotherapy with ifosfamide and etoposide (IE) 
(Matsuki, et al., 2016).  Lenvatinib also appears to be effective in sensitizing chemo-resistant 
osteosarcoma models.  Gene expression profiling studies (RNAseq analysis) conducted on 
5 human pediatric osteosarcoma xenograft models identified genes and signaling pathways 
associated with tumor response to the combination treatment (Lenvatinib + Ifosfamide + 
Etoposide) (Dezso, et al., 2016).  Genes included in these pathways were related to cell 
differentiation, RTKs, and angiogenic and pro-oncogenic pathways.  These genes and 
signaling pathways may be relevant targets of lenvatinib and everolimus, and have all been 
demonstrated to play key roles in the pathogenesis of pediatric sarcomas and HGGs (Pressey, 
et al., 2011; Oue, et al., 2010; Matushansky, et al., 2008).  For example, activation of Wnt/β-
catenin, SHH/PTCH/GLI1, BMP/TGF, and the HGF/MET axes have all been implicated in 
the development and progression of several soft tissue sarcomas and gliomas (Lin and Chen, 
2014; Graveel, et al., 2013; Yoshikawa, et al., 2004;).  The hyperactivation and 
overexpression of these pathways may also play critical roles in the development of 
chemoresistance (WNT5A) and can serve as prognostic biomarkers (FGF23, BMP2/4) 
(Hung, et al., 2014; Yoshikawa, et al., 2004;).   
An alternative angiogenic pathway is mediated by mammalian target of rapamycin (mTOR).  
mTOR is a serine/threonine kinase involved in integrating growth factor-activated and 
nutrient-sensing signals which regulate diverse cellular processes including growth, survival, 
differentiation, autophagy and metabolism (Shimobayashi, et al., 2014).  Deregulation of 
mTOR signaling has been described for numerous cancer types and familial cancer 
syndromes.  mTOR activation can result from the overexpression or presence of activating 
mutations in RTKs such as insulin like growth factor 1 receptor (IGF-1R), FGFR, or 
epidermal growth factor receptor (EGFR) and has been described in different solid tumors 
including various sarcoma subtypes and gliomas (Wan, et al., 2005).  Similarly, downstream 
mutations or overexpression of PI3K and Akt, or loss of tumor suppressor protein function,

have been associated with various tumors and cancer predisposition syndromes due to the 
aberrant activation of the TSC-Rheb-mTOR axis (Engelman, et al., 2006).  
Everolimus is an oral rapamycin analogue that forms a complex with FK506 Binding 
Protein-12 (FKBP12) and acts as a highly selective allosteric inhibitor of the mTOR 
complex 1 (mTORC1) causing the dissociation of regulatory-associated protein of mTOR 
(Raptor) and loss of mTORC1 substrate interactions (Chiarini, et al., 2015).  Everolimus has 
been FDA-approved for the treatment of various cancers including advanced renal 
carcinoma, unresectable neuroendocrine pancreatic adenocarcinoma, and advanced estrogen 
receptor-positive/HER2- breast carcinoma.  Most notably, everolimus has a pediatric specific 
approval for the treatment of subependymal giant cell astrocytoma (SEGA) associated with 
tuberous sclerosis (Franz, et al., 2012; Krueger, et al., 2010;).  The anti-tumor effects of 
everolimus have also been demonstrated in a number of in vitro and in vivo models of 
sarcomas including synovial sarcoma, osteosarcoma, chondrosarcoma, and leiomyosarcoma 
(Yasui, et al., 2014; Pignochino, et al., 2013; Perez, et al., 2012; Hernando, et al., 2007).  
These results provide a strong biologic rationale for further evaluating the role of everolimus 
in pediatric solid tumors. 
Proangiogenic signaling pathways (VEGF, FGF) cooperate with mTOR-mediated regulation 
of cell growth and maintenance to drive the development of pediatric solid tumors.  The 
agents that target both the proangiogenic pathways and mTOR signaling are attractive 
candidate agents for study.  Combinations of molecularly targeted agents guided by the 
genetics and biology of sarcoma may aid in overcoming the resistance that is inevitable with 
single-agent therapy by blocking several pathways critical to cancer progression.  This can be 
achieved by simultaneous inhibition of several mediators (eg, simultaneous inhibition of 
VEGF, FGF, platelet derived growth factor) or targeted inhibition at several levels within the 
same pathway (eg, inhibition of VEGF/mTOR/HIF).  Thus, a multi-target therapeutic 
approach may help overcome drug resistance leading to enhanced and prolonged efficacy.  
Indeed, combined VEGF and mTOR pathway inhibition has shown promise in preclinical 
solid tumor models (Molhoek, et al., 2008; Ikezoe, et al., 2006). 
Combination of the multi-RTKI sorafenib and the mTOR inhibitor, everolimus, has shown 
enhancement of the anti-angiogenic, anti-proliferative, and pro-apoptotic effects of RTK 
inhibition in various in vitro and in vivo solid tumor models including pancreatic cancer, 
hepatocellular carcinoma, mesothelioma, and osteosarcoma (Pignochino, et al., 2015; 
Pignochino, et al., 2013; Pawaskar, et al., 2013; Piguet, et al., 2011;).  
The combination of lenvatinib with everolimus has also been shown to exert a significantly 
higher anti-tumor effect compared to either agent alone in mouse models of renal cell 
carcinoma (Adachi, et al., 2016).  In xenograft models of Ewing sarcoma and osteosarcoma, 
the lenvatinib-everolimus combination was more potent in abrogating tumor growth than 
either agent alone (Eisai Co. Ltd. Data on File). 
Overcoming RTKI-induced resistance has been shown to be effectively accomplished by 
inhibiting alternative survival pathways.  In preclinical studies, sensitivity of 
lenvatinib-resistant tumor xenograft models was restored after sequential treatment with the

dual-RTKI, golvatinib which targets not only VEGFR, but also c-MET (Nakagawa, et al., 
2014).  mTOR inhibition is anticipated to abrogate several alternative survival pathways 
providing biologic rationale for combined treatment with lenvatinib and everolimus 
(Yasui, et al., 2014; Etnyre, et al., 2014; Imura, et al., 2014). 
A preclinical study of lenvatinib plus everolimus demonstrates enhanced inhibition of VEGF 
and FGF-induced angiogenesis than for either agent alone in human endothelial cell models 
(Mitsuhashi, et al., 2016).  The combination also showed synergistic enhancement against 
bFGF-driven angiogenesis, distinguishing this from other VEGFR2 tyrosine kinase inhibitors 
(TKIs).  Effects of lenvatinib, everolimus, and its combination on VEGF or bFGF activated 
intracellular signaling were analyzed in human umbilical vein endothelial cells (HUVEC) by 
western blotting.  Lenvatinib inhibited the VEGF or bFGF-driven phosphorylation of Erk1/2 
(Thr202/Tyr204), S6K (Thr389), and S6K (Thr421/Ser424), and S6 (Ser235/Ser236), 
indicating the inhibition of both the MAPK pathway and the mTOR-S6K-S6 pathway.  
Everolimus inhibited the phosphorylation of S6K (Thr389), S6K (Thr421/Ser424), and S6 
(Ser235/Ser236), but not Erk1/2.  The combination showed greater inhibition for the 
phosphorylation of S6K (Thr421/Ser424) and S6 (Ser235/Ser236) than each single agent.  
Combination effects of lenvatinib and everolimus on VEGF and bFGF-induced proliferation 
or tube formation of human umbilical vein endothelial cells (HUVEC) were examined using 
combination indexes.  Inhibitory activity of the combination at several molar ratios was 
mostly additive for VEGF-driven proliferation (combination index: 0.799-1.167) and mostly 
synergistic for bFGF-driven tube formation (combination index: 0.469-0.741).  Antitumor 
activities were tested in the KP-1/VEGF or KP-1/FGF models, where VEGF or FGF-induced 
tumor angiogenesis and tumor growth were enhanced in nude mice due to overexpressed 
VEGF or FGF in human pancreatic cancer KP-1cells (Mitsuhashi, et al., 2016).  In the KP-
1/VEGF or KP-1/FGF xenograft models, lenvatinib, everolimus, and the combination (orally, 
once daily x 14) significantly inhibited tumor growth compared to vehicle.  In addition the 
combination of lenvatinib (7.5 mg/kg) and everolimus (15 mg/kg) showed significantly 
greater antitumor activity than higher dose of either lenvatinib (10 mg/kg) or everolimus 
(30 mg/kg) monotherapy.  The vertical inhibition of angiogenic signaling pathways with 
lenvatinib (RTK) and everolimus (mTOR) may contribute to enhanced antiangiogenic 
activity by dual targeting of the mTOR-S6K-S6 pathway. 
In addition to the results obtained in the extensive in vitro and in vivo pre-clinical studies, the 
strong rationale for pediatric evaluation of the combination of lenvatinib and everolimus is 
the positive randomized trial in renal cell carcinoma resulting in FDA approval of lenvatinib 
combination with everolimus for patients with advanced renal cell carcinoma following 
1 prior antiangiogenic therapy.   
7.2 
Clinical Results Obtained with Combination Lenvatinib plus 
Everolimus Treatment  
The safety and efficacy of lenvatinib and everolimus combination treatment was investigated 
in the randomized, multi-center, open-label trial E7080-G000-205 (Study 205) in subjects 
with unresectable, advanced or metastatic RCC.  In the Phase 1b portion the recommended

Phase 2 dose (RP2D) for the lenvatinib/everolimus combination was determined as 
lenvatinib 18 mg plus everolimus 5 mg administered daily.  
The Phase 2 portion enrolled subjects with advanced or metastatic, clear-cell, renal cell 
carcinoma who had a history of receiving one prior VEGF agent.  A total of 153 subjects 
were randomized in a 1:1:1 ratio to receive treatment with lenvatinib (18 mg) plus 
everolimus (5 mg), lenvatinib (24 mg), or everolimus (10 mg) administered once daily. 
The primary analysis demonstrated median PFS for lenvatinib of 7.4 months (5.6-10.2, 95% 
confidence interval [CI]) vs everolimus 5.5 months (3.5-7.1) vs combination 14.6 months 
(5.9-20.1) with a hazard ratio (HR) of combination vs everolimus of 0.40 (0.24-0.68; 
p = 0.0005) and HR of lenvatinib vs everolimus of 0.61 (0.38-0.98; p = 0.0479).  The 
objective response rate (ORR) for lenvatinib was 27% (16-41), everolimus 6% (1-17%), and 
combination 43% (29-58%) with a median duration of objective response of lenvatinib 
7.5 months (3.8-not estimable), everolimus 8.5 months (7.5-9.4), and combination 
13.1 months (3.8-not estimable).  The ORR ratio between combination vs everolimus was 7.2 
(2.3-22.5; p <0.0001) and lenvatinib vs everolimus was 4.5 (1.4-14.7; p = 0.0067).  Updated 
overall survival analysis suggests a survival benefit for the combination over everolimus with 
an overall survival for lenvatinib of 19.1 months (13.6-26.2), everolimus 15.4 months 
(11.8-19.6), and the combination of 25.5 months (16.4-not estimable).  The HR for 
combination vs everolimus is 0.51 (0.30-0.88; p = 0.024) and 0.68 for lenvatinib vs 
everolimus (0.41-1.14; p = 0.118) in support of a potential survival benefit with combination 
therapy (Motzer, et al., 2015). 
The average duration of therapy for lenvatinib was 7.4 months (range 0.1-23.0), everolimus 
4.1 months (0.3-20.1), and combination 7.6 months (0.7-22.6).  The reported Grade 3/4 AEs 
included diarrhea, fatigue/asthenia, vomiting, nausea, hypertension, decreased weight and 
dyspnea.  Discontinuations due to AEs were as follows: lenvatinib 25%, everolimus 12%, 
and combination 24%.  The rates of AEs were generally higher for the combination arm, but 
they were predictable and generally managed with concomitant medication and dose 
modifications.

Pediatric Studies with Lenvatinib 
The safety, tolerability, and activity of lenvatinib in pediatric population is being evaluated in 
an ongoing Phase 1/2 study E7080-G000-207 (Study 207) of lenvatinib in children and 
adolescents with refractory or relapsed solid malignancies.  During Phase 1 portion of the 
study, the maximum tolerated dose (MTD) and a recommended dose of lenvatinib as a single 
agent in this subject population was identified.  The Time-to-Event Continuous Reassessment 
Method (TiTE-CRM) was used to identify the recommended dose of lenvatinib 
(Cheung, et al., 2000).  Twenty three subjects were enrolled across 3 dose groups.  Three of 
those subjects were treated at 11 mg/m2, 9 subjects were treated at 14 mg/m2, and 11 subjects 
were treated at 17 mg/m2.  Twenty of 23 enrolled subjects were evaluable for dose-limiting 
toxicity (DLT) assessment.  Three DLTs were reported at dose level 14 mg/m2, including 
alanine aminotransferase (ALT) increase (Grade 3), hypertension (Grade 3), and 
hypertension (Grade 4).  The Protocol Steering Committee (PSC) confirmed that the 14

mg/m2 was the recommended dose for single agent lenvatinib in children and adolescents 
with refractory or relapsed solid tumors (Eisai Co Ltd Data on File).  Phase 2 portion of 
Study 207 evaluating lenvatinib as a single agent or lenvatinib in combination with 
ifosfamide and etoposide in children and adolescents with osteosarcoma and 131I-refractory 
differentiated thyroid cancer is ongoing. 
7.4 
Study Rationale 
There remains a significant unmet medical need for more effective treatment options for 
pediatric subjects with solid tumors.  Overall solid tumors make up to 30% of all cancers in 
children.  Approximately 80% of these tumors are cured with conventional approaches.  This 
study will be performed on pediatric subjects with solid tumors, which were resistant to 
conventional therapy, and for whom there are no alternative therapies that might lead to cure. 
The proposed multicenter, Phase 1/2 study (E7080-G000-216) will determine (in Phase 1 
portion) a MTD and RP2D of lenvatinib administered in combination with everolimus.  
Phase 2 portion will estimate the antitumor activity, safety and tolerability of the lenvatinib 
and everolimus combination in pediatric subjects with recurrent/refractory solid tumors 
including HGG, rhabdomyosarcoma, and Ewing’s sarcoma/pPNET. 
The initial dose level (Dose Level 1) for lenvatinib will be 11 mg/m2, which is approximately 
80% of lenvatinib single dose MTD in pediatric subjects determined in the ongoing 
Study 207.  The initial dose of everolimus will be 3 mg/m2, which is 66% of the FDA 
approved dose and a dose previously found to be effective in subependymal giant cell 
astrocytoma (SEGA), as per everolimus package insert (Afinitor package insert). 
Due to a lower starting dose determined for adult subjects with hepatocellular cancer (HCC): 
12 mg (baseline body weight [BW] ≥60 kg) or 8 mg (baseline BW <60 kg) given once daily 
for the Phase 3 study in subjects with HCC, as opposed to the approved dose of lenvatinib 
monotherapy in adult subjects with differentiated thyroid cancer, which is 24 mg once daily, 
subjects with hepatoblastoma will be excluded from participation in this study.

Phase 1 Dose Escalation and Determination of the MTD 
The Phase 1 component is a dose escalation study with treatment in sequential cohorts of 
escalating doses of lenvatinib in combination with everolimus, each administered once daily 
in 28-day treatment cycles.  Pediatric subjects with a relapsed/refractory solid malignancy, 
including primary brain tumors are eligible to enroll.  The initial dose level (Dose Level 1) 
for lenvatinib will be 11 mg/m2.  The initial dose of everolimus will be 3 mg/m2.  Dose 
Level 2 will escalate lenvatinib by approximately 25% to 14 mg/m2 and maintain everolimus 
at the same dose of 3 mg/m2.  At Dose Levels -1 and 1, maximum daily dose of lenvatinib 
will not exceed 18 mg daily.  At Dose Level 2, maximum daily dose of lenvatinib allowed 
will not exceed 24 mg.  Should Dose Level 2 be well tolerated, Dose Level 3 may be 
considered to test lenvatinib at 14 mg/m2 (capped at 24 mg) and escalate everolimus to 
4.5 mg/m2.  For everolimus dose levels of 3 mg/m2 and 4.5 mg/m2, the maximum daily dose 
of everolimus will not exceed 5 mg and 7 mg, respectively.  If the MTD for combination of 
lenvatinib and everolimus has been exceeded at Dose Level 1, then the subsequent cohort of 
subjects will be treated at Dose Level ˗1 with dose of lenvatinib 8 mg/m2 and dose of 
everolimus 3 mg/m2 (Table 1).  Intra-subject titration of everolimus will not be allowed on 
this study. 
At study entry, subjects must have a minimum BSA of 0.6 m2.

The Phase 1 portion of the study will utilize a rolling 6 design (Skolnik, et al., 2008).  Two to 
6 subjects can be concurrently enrolled into a dose level cohort.   
Dose level assignment will be based on:  
1. the number of subjects currently enrolled in the dose level cohort,  
2. the number of DLTs observed, and  
3. the number of subjects at risk for developing a DLT (ie, subjects enrolled but who are not 
yet assessable for toxicity).   
For example, when 3 subjects are enrolled onto a dose cohort, if toxicity data is available for 
all 3 when the fourth subject entered and there are no DLTs, the dose will be escalated and 
the fourth subject will be treated at the subsequent dose level.  If data is not yet available for 
1 or more of the first 3 subjects and no DLT has been observed, or if one DLT has been 
observed, the new subject will be treated at the same dose level.  Lastly, if 2 or more DLTs 
have been observed, the dose level will be de-escalated.  This process will be repeated for 
Subjects 5 and 6.  In place of suspending accrual after every 3 subjects, accrual will be 
suspended when a cohort of 6 potentially evaluable subjects has enrolled (ie, subjects 
enrolled but are not yet assessable for toxicity) or when the study endpoints have been met.  
When subjects are not evaluable for toxicity, they will be replaced with the next available 
subject if escalation or de-escalation rules have not been fulfilled at the time the next 
available subject is enrolled in the study. 
The following table (Table 2) provides the decision rules for enrolling a subject at (i) the 
current dose level (ii) at an escalated dose level, (iii) at a de-escalated dose level, or whether 
the study is suspended to accrual:

considered (if one of the DLTs does not appear to be dose-related, the Adverse Effects are

All subjects in the Phase 1 Dose Escalation phase will have samples taken for PK analysis 
with the intent at the end of Phase 1 of having evaluable PK data from minimally 6 subjects 
aged 2 to <6 years old, 6 subjects ≥6 to <12 years old, and 6 subjects ≥12 years old.  Once 
the MTD or RP2D has been defined, 0 to 6 additional subjects will be enrolled to attain the 
goal of having evaluable PK data from minimally 6 subjects aged 2 to <6 years old, 
6 subjects ≥6 to <12 years old, and 6 subjects ≥12 years old.  
Protocol Steering Committee 
The sponsor will closely evaluate the risks and benefits of the study throughout its conduct, 
along with the PSC as needed.  The PSC may review available relevant data:  DLT and safety 
data including laboratory assessments, 12-lead electrocardiograms (ECGs), dose 
administration, etc. 
Toxicity Monitoring 
The DLT observation period for the purposes of dose-escalation will be the first cycle of 
therapy.  Routine Phase 1 monitoring for clinical and laboratory toxicities will be used.  
Blood pressure (BP) monitoring will occur at least weekly during the first 2 cycles.   
Dose-Limiting Toxicity 
Dose-limiting toxicity will be assessed according to Common Terminology Criteria for 
Adverse Events (CTCAE) v4.03 and is defined as any of the following events that are 
possibly, probably, or definitely attributable to lenvatinib or everolimus.  Dose-limiting 
hematological and non-hematological toxicities are defined differently. 
A. Non-hematological DLT: 
 Any Grade 3 or greater non-hematological toxicity attributable to the investigational 
drug with the specific exclusion of: 
o Grade 3 nausea and vomiting <3 days duration 
o Grade 3 diarrhea <3 days duration 
o Grade 3 weight loss 
o Grade 3 liver enzyme elevation, including ALT/aspartate aminotransferase (AST)/ 
gamma glutamyl transferase (GGT)/ bilirubin/alkaline phosphatase that returns to 
Grade 1 or baseline within 7 days 
o Grade 3 asymptomatic elevation in amylase or lipase that returns to Grade 1 or 
baseline within 7 days 
o Grade 3 elevation in triglycerides that returns to Grade 1 or baseline within 7 days 
o Grade 3 or 4 fever <5 days duration 
o Grade 3 infection <5 days duration 
o Grade 3 hypophosphatemia, hypokalemia, hypocalcemia or hypomagnesemia 
responsive to oral supplementation 
o Grade 3 proteinuria (UPC) ratio >1.9 unless confirmed with a second measurement 
within 72 hours 
o Grade 3 headache <3 days duration responsive to optimal management.

 Any Grade 2 non-hematological toxicity that persists for ≥7 days and is considered 
sufficiently medically significant or sufficiently intolerable by subjects despite 
optimal supportive care that it requires treatment interruption. 
 Any dose interruption or reduction due to toxicity which results in administration of 
less than 75% of the planned dosage of lenvatinib and/or everolimus. 
 Note:  Allergic reactions that necessitate discontinuation of study drug will not be 
considered a DLT. 
 Dose-limiting hypertension: 
o Any Grade 4 hypertension  
Confirmed systolic or diastolic BP more than 25 mmHg above 95th percentile for sex, age, 
height/length, or an elevated diastolic BP (ie, >95th percentile for age) not controlled by a 
single antihypertensive medication within 14 days of use.  An antihypertensive tablet or 
capsule that contains up to 2 antihypertensive ingredient medications will be considered a 
single antihypertensive medication. 
B. Hematological DLT:    
 In subjects evaluable for hematological toxicity, DLT is defined as: 
o Grade 4 thrombocytopenia (platelet count <25,000/mm3) or Grade 4 neutropenia, 
not due to malignant infiltration. 
 Any ≥Grade 2 arterial thromboembolic events (including cerebrovascular ischemia, 
peripheral or visceral arterial ischemia). 
 Note:  Grade 3 or 4 febrile neutropenia will not be considered a DLT. 
All DLTs must be reported to the sponsor within 24 hours of their occurrence.  
Determination of a DLT will be made by the investigator and the Eisai Medical Monitor in 
consultation with the PSC, as needed.  Subjects who discontinue the study treatment for any 
reason other than DLT (eg, early disease progression) during Cycle 1 (Day 1 to Day 28), and 
have not received at least 75% of the prescribed dose prior to discontinuation, will be 
replaced. 
The sponsor and PSC will review all subjects’ safety and clinical data to jointly determine 
the MTD/RP2D of the combination of lenvatinib with everolimus.  The Treatment Phase for 
each subject in Phase 1 ends after completing Cycle 1 of treatment unless subject 
discontinues early.  Those subjects who discontinue study treatment in Cycle 1 transition to 
the Off-treatment Visit.  Those who complete Cycle 1 will transition to the Extension Phase.  
Study treatment and tumor assessments will continue during the Extension Phase. 
Phase 2 Cohorts 
Once the MTD/RP2D of the combination of lenvatinib and everolimus in pediatric 
population has been determined in Phase 1, the Phase 2 portion of this pediatric study will 
commence with Cohort 1 (recurrent or refractory Ewing sarcoma/pPNET), Cohort 2 
(recurrent or refractory rhabdomyosarcoma), and Cohort 3 (recurrent or refractory HGG), 
opening to accrual.

10 evaluable subjects will be enrolled to each stage.  The Sponsor will closely monitor 
enrollment to ensure that at least 50% of subjects enrolled in each cohort are <18 years of age 
at the time of informed consent.  The primary outcome measure for Ewing sarcoma/pPNET, 
rhabdomyosarcoma, and HGG will be ORR (complete or partial response) at 16 weeks.  If 
there are no responses among the 10 subjects in Stage 1, then the enrollment to that disease 
cohort will stop and conclude that the lenvatinib/everolimus combination therapy does not 
elicit a response in that disease cohort.  If there is at least 1 response in the first stage, then 
the second stage will enroll 10 additional evaluable subjects.  If there are 2 or fewer 
responses among the 20 evaluable subjects, then lenvatinib/everolimus combination therapy 
will be declared a failure for that disease cohort. Subjects will meet the criteria for being 
evaluable for an objective response if they have measurable disease present at baseline and at 
least 1 post-baseline efficacy assessment, unless they have discontinued prior to the first 
efficacy assessment due to progressive disease. Subjects who are not evaluable for objective 
response will be replaced. 
The Treatment Phase for each subject in Phase 2 ends after completing 4 cycles of treatment 
unless subject discontinues early.  Those subjects who discontinue study treatment before 
completing 4 cycles transition to the Off-treatment Visit.  Those who complete 4 cycles will 
transition to the Extension Phase.  Study treatment and tumor assessments will continue 
during the Extension Phase. 
Dosing Nomogram  
The dose nomogram in Table 3 provides the dose of lenvatinib to be administered for BSA 
increments starting from 0.6 m2.  BSA must be calculated on Day 1 of each cycle based on 
the subject’s current height and body weight.  The actual dose to be administered is rounded 
to the nearest whole number.  The total lenvatinib dose is capped at 18 mg daily (Dose 
Levels -1 and 1), and at 24 mg (Dose Levels 2 and 3).

Study Duration 
Approximately a total of 4.5 years from the first subject providing signed informed consent 
in Phase 1 to the primary endpoint completion date for Phase 2 of the study.  It is estimated 
that the Phase 2 portion will take 3 years in order to complete the final collection of data for 
the primary outcome analysis. 
Study duration for each subject is estimated to be: 
 
Pretreatment Phase:  4 weeks 
 
Treatment Phase:  1 cycle (4 weeks) in Phase 1; 4 cycles (16 weeks) in Phase 2. 
 
Extension Phase:  Estimated maximum time of treatment is 2 years (24 cycles).  
Subjects may remain on study treatment as long as they do not meet any of the following 
criteria:  1) experience objective progression of disease (according to RECIST 1.1 or 
RANO, as appropriate), 2) exhibit no clinical benefit (in the opinion of the investigator), 
3) experience unacceptable toxicity leading to withdrawal from the study, 4) withdraw or 
are withdrawn from the study for any reason, or, 5) termination of the study program.  As 
long as the subject has not experienced intolerable toxicity, he or she can continue to 
receive study treatment.  A 28-day follow up visit from last date of receiving 
investigational drug will be performed for subjects who discontinue study treatment. 
9.1.1 
Pretreatment Phase 
The Pretreatment Phase will last up to 28 days and will include a Screening Period and a 
Baseline Period. 
9.1.1.1 
Screening Period 
Screening will occur between Day –28 and Day –2.  The purpose of the Screening Period is 
to obtain informed consent and to establish protocol eligibility.  Informed consent will be 
obtained after the study has been fully explained to each subject and before the conduct of

any screening procedures or assessments.  Procedures to be followed when obtaining 
informed consent are detailed in Section 5.3. 
The Screening Disposition case report form (CRF) must be completed to indicate whether the 
subject is eligible to enroll in the study and to provide reasons for screen failure, if 
applicable. 
The results of all screening assessments and evaluations must be completed and reviewed by 
the investigator prior to the Baseline Visit.  
9.1.1.2 
Baseline Period 
The purpose of the Baseline Period is to confirm protocol eligibility as specified in the 
inclusion/exclusion criteria (as detailed in Section 9.3.1 and Section 9.3.2).  Results of 
baseline assessments must be obtained prior to the first dose of study treatment (Cycle 1 
Day 1).  Baseline assessments can be performed on Day –1 or on Cycle 1 Day 1 prior to start 
of study treatment.   
Subjects who complete the baseline assessments and continue to meet the criteria for 
inclusion/exclusion (Sections 9.3.1 and 9.3.2) will begin the Treatment Phase. 
9.1.2 
Treatment Phase 
The Treatment Phase will begin with the first dose of study drug administration in Cycle 1.  
The duration of the Treatment Phase is 1 cycle (4 weeks of treatment) in Phase 1 of the 
study, and 4 cycles (16 weeks of treatment) in Phase 2 of the study.  Subjects will receive 
study treatment in 28-day cycles.  Tumor assessments will be performed during the 
Treatment Phase at Week 4 ±1 week (Phase 1) and at Week 8 ±1 week and Week 16 ±1 week 
(Phase 2). 
Subjects who discontinue study treatment during Cycle 1 (Phase 1), or before completing 
4 cycles of treatment (Phase 2), will transition to the Off-treatment Visit.  
9.1.3 
Extension Phase 
All subjects who are still on study treatment following completion of Cycle 1 in Phase 1, or 
after completing 4 cycles in Phase 2 of the study, will transition to the Extension Phase.  
During the Extension Phase, subjects will continue to receive the same study treatment in 
28-day cycles.  Tumor assessments will be performed during the Extension Phase at Week 12 
±1 week and Week 24 ±1 week, and every 12 weeks ±1 week thereafter (Phase 1) and at 
Week 24 ±1 week, and every 12 weeks ±1 week thereafter (Phase 2). 
9.1.4 
Treatment Discontinuation Criteria  
Subjects may remain on study treatment as long as they do not meet any of the following 
criteria:  1) experience objective progression of disease (according to Response Evaluation 
Criteria in Solid Tumors [RECIST] 1.1 or Response Assessment in Neuro-Oncology

[RANO] criteria, as appropriate), 2) exhibit no clinical benefit (in the opinion of the 
investigator), 3) experience unacceptable toxicity leading to withdrawal from the study, 
4) withdraw or are withdrawn from the study for any reason, or, 5) termination of the study 
program.  
As long as the subject has not experienced intolerable toxicity, he or she can continue to 
receive study treatment.   
9.1.5 
Off-Treatment Visit 
After subject discontinues treatment, an Off-Treatment Visit and the procedures noted in the 
Schedule of Assessments (Table 7 and Table 8) should be completed within 28 days after the 
last dose of study treatment.   
9.1.6 
Post-Treatment Phase 
9.1.6.1 
Follow-Up Period 
The post-treatment follow up will begin when the subject discontinues study treatment and 
all off-treatment assessments have been completed.  Subjects who discontinue study 
treatment for reasons other than disease progression will be followed for documented disease 
progression for 1 year or until another anticancer therapy is initiated whichever occurs first.  
Subjects will be followed for survival every 3 months until death or for 1 year, whichever 
occurs first, unless the study is terminated or if the subject discontinues due to withdrawal of 
consent or is lost to follow up. 
After data cutoff, tumor assessments may be performed as clinically indicated using the 
institutional guidelines, following the prevailing local standard of care. 
As required by some regulatory agencies, the following estimates are provided:  
 
The study is planned to begin in April 2017 and to end in March 2022.   
 
The maximum estimated period for each subject on study is anticipated to be 
approximately 2 years (24 treatment cycles).  However, subjects will continue to receive 
study treatment as long as they demonstrate clinical benefit. 
9.2 
Discussion of Study Design 
This multicenter, open-label, Phase 1/2 study will investigate safety, tolerability and 
antitumor activity of lenvatinib in combination with everolimus in pediatric subjects with 
relapsed or refractory solid tumors.   
The Phase 1 portion of the study utilizes dose-finding rolling 6 design (Skolnik, et al., 2008), 
which allows enrollment of more than 3 subjects at the particular dose level, unlike the 
traditional 3+3 Phase 1 study design.  If there is no DLTs in the first 3 subjects enrolled 
under rolling 6 design, then the fourth subject can be allocated to the next higher dose level.  
If toxicity data are not available on the first 3 subjects, or if one DLT is observed, in which

case the new subject will be kept at the same dose level.  The main advantage of the rolling 6 
design is the reduction of the overall study duration as it aims to decrease the number of 
times the study is suspended to accrual.  
The Simon-optimal 2-stage design utilized for Phase 2 portion of the study allows for interim 
evaluation for futility.  The traditional single-stage study designs evaluate drug response rate 
on the predetermined number of subjects, possibly unnecessarily exposing children to the 
risk of ineffective new agents.  For ethical reasons, Simon’s 2-stage design utilizes a small 
number of subjects to determine drug activity and allows early termination of the study if 
activity criteria are not met.  This prevents exposure of too many pediatric subjects to an 
inactive study drug. 
Toxicity will be assessed according to National Cancer Institute’s CTCAE v4.03.  In this 
study, the subjects will remain on treatment as long as they do not experience progression of 
disease or unacceptable toxicity.  This will allow evaluation of short-term toxicity, as well as, 
side effects after prolonged use of combination of lenvatinib and everolimus, which is 
particularly important for pediatric population where physical growth and tissue maturation 
continues. 
9.3 
Selection of Study Population 
A maximum accrual of 120 subjects in Phase 1 and Phase 2 portions of the study is expected 
at approximately 60 sites (20 sites for the Phase 1 portion and an additional 40 sites for the 
Phase 2 portion).   
Phase 1:  4 to 48 evaluable subjects.  In the event that each of the Dose Levels -1, 1, 2 , and 
3 is expanded to 12 subjects, a maximum of 54 subjects (allowing for 20% to be 
non-evaluable and including the additional 6 subjects for PK analysis) will be enrolled. 
Phase 2 Cohorts 1 to 3:  10 to 20 evaluable subjects per cohort (maximum 22 subjects per 
cohort allowing for 10% to be non-evaluable).  A maximum of 66 subjects will be enrolled in 
Phase 2.  In each cohort, at least 50% of the subjects enrolled will be <18 years old at the 
time of informed consent. 
Subjects who do not meet all of the inclusion criteria or who meet any of the exclusion 
criteria will not be eligible to receive study treatment. 
9.3.1 
Inclusion Criteria

donation is allowed during the study period and for 7 days after lenvatinib 
discontinuation or 4 weeks after discontinuation of everolimus. 
9.3.3 
Removal of Subjects From Therapy or Assessment 
The investigator may discontinue treating a subject with study treatment or withdraw the 
subject from the study at any time for safety or administrative reasons.  The subject may 
decide to discontinue study treatment or withdraw from the study at any time for any reason.

The reason for discontinuation will be documented.  If a subject discontinues study 
treatment, the subject will enter the Follow-Up Period and complete survival follow-up 
unless the subject withdraws consent.  The investigator should confirm whether a subject will 
withdraw from study treatment but agree to continue protocol-specified, off-treatment study 
visits, procedures, and survival follow-up, or whether the subject will withdraw consent.  If a 
subject withdraws consent, the date will be documented in the source documents.  The 
Subject Disposition CRF will be completed indicating the primary reason for discontinuation 
and all other reason(s) contributing to the subject’s discontinuation from treatment.  In 
addition, the date of last dose of study drug(s) will be recorded on the Study Medication

Treatment 
9.4.1 
Treatment Administered 
Lenvatinib will be provided as hard capsules containing 1 mg, 4 mg, or 10 mg lenvatinib.  An 
extemporaneous suspension of lenvatinib capsules should be used for children unable to 
swallow capsules (Appendix 12). 
Everolimus will be provided as 2 mg, 3 mg, and 5 mg dispersible tablet formulations 
(everolimus tablets for oral suspension).   
Lenvatinib and everolimus will be administered orally on a once daily schedule in continuous 
28-day cycles.  The sequence of administration is not important.  Dosing nomograms based 
on BSA and dose level will be used to prescribe lenvatinib and everolimus for subjects to 
minimize inter-subject dosing variability.  The maximum daily dose of lenvatinib 
administered during the study should not exceed 18 mg in Dose Levels -1, and 1, and 24 mg 
in Dose Levels 2 and 3.  The maximum daily dose of everolimus should not exceed 5 mg in 
Dose Levels -1, 1, and 2, and 7 mg in Dose Level 3.  Intra-subject titration of everolimus will 
not be allowed on this study.  Intra-subject dose escalation of both lenvatinib and everolimus 
will not be allowed. 
Subjects benefiting from study treatment in the opinion of the investigator will continue 
treatment until disease progression, development of unacceptable toxicity, withdrawal of 
consent or are withdrawn from the study for any reason, or termination of the study by the 
sponsor. 
9.4.1.1 
Study Treatment Dose Reduction and Interruption Instructions 
Dose reduction and interruptions for subjects who experience lenvatinib-everolimus 
combination therapy-related toxicity will be managed as described in Table 5.  Investigators 
will decide the probability of the event being related to protocol therapy as to whether dose 
modification of drug therapy is required. 
Doses in the Dose Adjustment column are based on a presumed starting dose of 11 mg/m2 
lenvatinib and 3 mg/m2 everolimus.  Dose reductions will occur in succession based on the 
previous dose level.  Each dose level reduction due to toxicity at a given BSA is

approximately 25% reduction from the previous dose.  Once the study drug dose has been 
reduced, it may not be increased at a later date, unless the dose was mistakenly decreased; in 
this situation, the sponsor’s approval is required to increase the dose. 
Asymptomatic laboratory abnormalities, including Grade ≥3 abnormalities (eg, elevations of 
amylase and lipase) that are not considered clinically relevant by the investigator, should be 
managed per institutional guidelines; continuation of treatment should be discussed with the 
sponsor.

Grade 1weight loss).  These subjects will restart the study drug(s) at a lower dose once their weight remains 
stable for at least 1 week and they reached the normal body mass index (BMI; if the weight loss occurred but it 
is still above normal BMI, they can restart the study treatment at a lower dose once the weight has been stable 
for at least 1 week).  Normal BMI should be used as the new baseline for further dose reductions.  See BMI 
charts for boys (Appendix 9) and girls (Appendix 10). 
e: For Grade 2 toxicity, resume everolimus at the same dose as prior to dose interruption.  For Grade 3 toxicity, 
investigator will decide the probability of the event being related to one or both drugs as to whether dose 
modification of one or both drugs is required.

9.4.1.2 
Blood Pressure 
For children, BP varies by the sex and age of the child and it is closely related to height and 
weight.  BP will be assessed in terms of percentile for sex, age and height/length.  Guidelines 
to sex, age, and height-specific percentiles of BP are provided in Appendix 7 and  
Appendix 8.  BP that is consistently above the 95th percentile [for subjects age 18-21 years 
BP ≥140/90 mmHg] for age and height/length requires further evaluation.  A referral to a 
cardiologist is recommended for subjects who develop hypertension during the study.  
Ideally, cardiovascular assessments and the management of hypertension should be 
supervised by a cardiologist.  Exercise, excitement, coughing, crying and struggling may 
raise the systolic pressure of children as much as 40 to 50 mmHg greater than their usual 
level.  Variability in BP in children of approximately the same age and body build should be 
expected and serial measurements should always be obtained when evaluating a subject with 
hypertension.  BP values for management of hypertension for subjects 18 to 21 years of 
age are included in parenthesis. 
9.4.1.3 
Management of Hypertension 
Hypertension is a recognized side-effect of treatment with drugs inhibiting VEGF signaling.  
Investigators should therefore ensure that subjects enrolled to receive treatment with 
lenvatinib have BP <95th percentile [BP ≤150/90 mmHg] for sex, age, and height/length at 
the time of study entry and, if known to be hypertensive, have been on a stable dose of 
antihypertensive therapy for at least 1 week before Cycle 1 Day 1.  Early detection and

effective management of hypertension are important to minimize the need for dose 
interruptions and reductions.  Antihypertensive agents should be started as soon as elevated 
BP (systolic BP ≥95th percentile [BP ≥140 mmHg] or diastolic BP ≥95th percentile [BP 
≥90 mmHg]) is confirmed on 2 assessments obtained 1 hour apart.  One BP assessment is 
defined as the mean value of 3 measurements obtained at least 5 minutes apart.  The choice 
of antihypertensive treatment should be individualized to the subject’s clinical circumstances 
and follow standard medical practice.  For previously normotensive subjects, monotherapy 
with one of the classes of antihypertensives should be started when systolic BP 
≥95th percentile [BP ≥140 mmHg] or diastolic BP ≥95th percentile [BP ≥90 mmHg] is first 
observed on 2 assessments obtained 1 hour apart.  For those subjects already on 
antihypertensive medication, the dose of the current agent may be increased, if appropriate, 
or 1 or more agents of a different class of antihypertensive should be added.  For subjects 
with hypertension and proteinuria, treatment with an angiotensin-converting enzyme (ACE) 
inhibitor or angiotensin-II receptor antagonist is preferred.  
Study treatment should be withheld in any instances where a subject is at imminent risk to 
develop a hypertensive crisis or has significant risk factors for severe complications of 
uncontrolled hypertension (eg, BP ≥99th percentile [BP ≥160/100 mmHg], significant risk 
factors for cardiac disease, intracerebral hemorrhage, or other significant comorbidities).  
Once the subject has been on the same antihypertensive medications for at least 48 hours and 
the BP is controlled, study treatment should be resumed as described below.  
During the Treatment Period, subjects with systolic BP ≥99th percentile [BP ≥160 mmHg] or 
diastolic BP ≥99th percentile [BP ≥100 mmHg] must have their BP monitored every 2 weeks 
(on Day 15 or more frequently as clinically indicated) until systolic BP has been 
<95th percentile [≤150 mmHg] and diastolic BP has been <95th percentile [≤95 mmHg] for 
3 consecutive months.  If a new event of systolic BP ≥99th percentile [BP ≥160 mmHg] or 
diastolic BP ≥99th percentile [BP ≥100 mmHg] occurs, the subject must resume the Day 15 
evaluation until systolic BP has been <95th percentile [≤150 mmHg] and diastolic BP has 
been <95th percentile [≤95 mmHg] for 3 consecutive months.  
The following guidelines should be followed for the management of systolic BP ≥99th 
percentile [BP ≥160 mmHg] or diastolic BP ≥99th percentile [BP ≥100 mmHg] confirmed on 
repeat measurements after an hour:  
 
Continue study treatment and institute antihypertensive therapy for subjects not 
already receiving antihypertensive medication.  
 
For those subjects already on antihypertensive medication, the dose of the current 
agent may be increased, if appropriate, or 1 or more agents of a different class of 
antihypertensive should be added.  
 
If systolic BP ≥99th percentile (BP ≥160 mmHg) or diastolic BP ≥99th percentile 
(BP ≥100 mmHg) persists despite maximal antihypertensive therapy, then study 
treatment administration should be interrupted and restarted at a lower dose once 
daily (one dose level reduction as specified in Table 5) only when systolic BP 
<95th percentile (BP ≤150 mmHg) and diastolic BP <95th percentile (BP

≤95 mmHg) and the subject has been on a stable dose of antihypertensive medication 
for at least 48 hours.  
o If systolic BP ≥99th percentile (BP ≥160 mmHg) or diastolic BP 
≥99th percentile (BP ≥100 mmHg) recurs despite optimal management of 
hypertension with antihypertensive medications (either by dose increase or the 
addition of a different class of antihypertensive), then study treatment 
administration should be interrupted and restarted at a lower dose once daily 
(one dose level reduction as specified in the Table 5) only when systolic 
BP <95th percentile (BP ≤150 mmHg) and diastolic BP <95th percentile ([BP 
≤95 mmHg] and the subject has been on a stable dose of antihypertensive 
medication for at least 48 hours.  
o If systolic BP ≥99th percentile ([BP ≥160 mmHg) or diastolic BP 
≥99th percentile ([BP ≥100 mmHg] recurs despite optimal management of 
hypertension with antihypertensive medications (either by dose increase or the 
addition of a different class of antihypertensive), then study treatment 
administration should be interrupted and a restart of treatment should be 
discussed with the sponsor.  
The following guidelines should be followed for the management of Grade 4 hypertension 
(life-threatening consequences):  
 
Institute appropriate medical management 
 
Discontinue study treatment

Posterior Reversible Leukoencephalopathy Syndrome/ Reversible Posterior 
Leukoencephalopathy Syndrome (PRES/RPLS) is a neurological disorder that can present 
with headache, seizure, lethargy, confusion, altered mental function, blindness, and other 
visual or neurological disturbances.  Mild to severe hypertension may be present.  MRI is 
necessary to confirm the diagnosis of PRES/RPLS.  Appropriate measures should be taken to 
control BP.  In subjects with signs or symptoms of PRES/RPLS, the Dose Modification 
Guidelines (Table 5) should be followed.  
9.4.1.5 
Management of Proteinuria 
Regular assessment for proteinuria should be conducted as detailed in the Schedule of 
Assessments (Table 7 and Table 8).  Guidelines for assessment and management of 
proteinuria are summarized as follows:  
1. Grading according to CTCAE v4.03 will be based on the protein-creatinine ratio, and 
whenever possible, also on the 24-hour urinary protein result per investigator’s

discretion.  Management of study treatment administration will be based on the grade of 
proteinuria according to the Dose Modification Guidelines. 
2. A spot protein-creatinine ratio test, and if possible a 24-hour urinary protein test as per 
investigator’s discretion, to verify the grade of proteinuria is required in the following 
situations: 
 The first (initial) occurrence of ≥2+ proteinuria on urine dipstick while on study 
treatment 
 A subsequent increase in severity of urine dipstick proteinuria occurring on the same 
lenvatinib/everolimus dose level 
 When there has been a lenvatinib/everolimus dose reduction and at the new dose level 
the urine protein dipstick result is 2+, 3+, or 4+ 
3. Urine dipstick testing for subjects with proteinuria ≥2+ should be performed every 
2 weeks (or on Day 1 and Day 15 or more frequently as clinically indicated) until the 
results have been 1+ or negative for 3 consecutive months.   
4. In the event of nephrotic syndrome, lenvatinib must be discontinued. 
9.4.1.6 
Management of Diarrhea 
An anti-diarrheal agent should be recommended to the subject at the start of study treatment 
and subjects should be instructed and educated to initiate anti-diarrheal treatment at the first 
onset of soft bowel movements.  The choice of anti-diarrheal agent should be individualized 
to the subject’s clinical circumstances and follow standard medical practice.  If 
signs/symptoms of diarrhea persist despite optimal medical management, instructions 
contained in the Dose Modification Guidelines should be followed. 
9.4.1.7 
Management of Non-Infectious Pneumonitis 
Non-infectious pneumonitis is a recognized class effect of rapamycin derivatives, including 
everolimus.  Non-infectious pneumonitis was described in 19% of subjects taking everolimus 
(Afinitor package insert).  Some cases were severe and on rare occasions, a fatal outcome 
was observed.  Investigators should therefore consider a diagnosis of non-infectious 
pneumonitis in subjects presenting with non-specific respiratory signs and symptoms and in 
whom infectious, neoplastic and other non-medicinal causes have been excluded by means of 
appropriate investigations. 
Subjects who develop radiological changes suggestive of non-infectious pneumonitis and 
have few or no symptoms (Common Terminology Criteria for Adverse Events [CTCAE] 
Grade 1) may continue study dosing without dose adjustments. 
1. If symptoms are moderate (CTCAE Grade 2): 
 Study treatment (lenvatinib-everolimus combination) should be interrupted and the 
use of corticosteroids may be indicated until symptoms abate (resolved to CTCAE 
Grade 0-1) and may then be restarted at the same doses prior to study treatment 
interruption.

 If Grade 2 non-infectious pneumonitis recurs despite optimal management, then study 
treatment administration should be interrupted and the use of corticosteroids may be 
indicated until symptoms abate (resolved to CTCAE Grade 0-1).   
2. If symptoms are severe (CTCAE Grade 3): 
 Study treatment should be interrupted and the use of corticosteroids may be indicated 
until clinical symptoms resolve (to CTCAE Grade 0-1).   
3. If symptoms are life-threatening (CTCAE Grade 4): 
 Study medications should be discontinued. 
9.4.1.8 
Management of Infections 
Everolimus has immunosuppressive properties and may predispose subjects to infections.  It 
is important therefore to monitor for signs and symptoms of infection, and treat promptly.  
Dose alterations of everolimus may be required in accordance with everolimus prescribing 
information, ie, Afinitor Disperz package insert or Votubia Summary of Product 
Characteristics (SmPC). 
9.4.1.9 
Management of Blood Glucose and Lipids 
Hyperglycemia, hyperlipidemia and hypertriglyceridemia are recognized class effects of 
rapamycin derivatives, including everolimus.  Glycemic and lipid control should be 
optimized before starting a subject on this study.  Blood glucose will be monitored as 
specified in the Schedule of Procedures/Assessments.  For subjects with blood glucose 
>ULN, a fasting (>6 hour, water only) blood glucose sample will be obtained.  Grading will 
be based on the fasting blood glucose result.  The choice of hypoglycemic agent should be 
individualized to the subject’s clinical circumstances and follow standard medical practice.  
Dose alterations of everolimus may be required in accordance with everolimus prescribing 
information, ie, Afinitor Disperz package insert or Votubia SmPC. 
9.4.1.10 
Management of Hepatotoxicity 
Regular monitoring of liver function tests (ALT, AST, bilirubin levels) should be conducted 
as detailed in the Schedule of Assessments (Table 7 and Table 8) and as clinically indicated.  
If signs/symptoms indicating liver injury occur, instructions contained in the table for dose 
reduction and interruptions of the protocol should be followed (see Table 5), for Study 
Treatment Dose Reduction and Interruption Instructions).  Appropriate supportive care 
should be provided together with close monitoring.  If hepatic failure occurs the study 
treatment must be discontinued. 
9.4.1.11 
Management of Thromboembolic Events 
Subjects should be advised to pay attention to symptoms suggestive of venous 
thromboembolic events which include acute onset of shortness of breath, dyspnea, chest pain, 
cough, hemoptysis, tachypnea, tachycardia, cyanosis, deep vein thrombosis signs including 
lower-extremity swelling, redness and warmth to touch or tenderness.  In case any of these 
symptoms appear, subjects should be instructed to report such symptoms promptly to the 

Clinical Study Protocol 
incorporating Amendment 03

treating physician.  If a thromboembolic event is confirmed, instructions contained in the 
table for dose reduction and interruptions of the protocol should be followed, (see Table 5), 
for Study Treatment Dose Reduction and Interruption Instructions).  Appropriate supportive 
care should be provided together with close monitoring.  If a subject experiences 
life-threatening (Grade 4) thromboembolic reactions, including pulmonary embolism, the 
study treatment must be discontinued.  If a subject experiences an arterial thromboembolism 
event of any grade, lenvatinib must be discontinued. 
9.4.1.12 
Management of Hypocalcemia 
Serum calcium should be monitored per the Schedule of Assessments.  Corrected serum 
calcium should be used to assess the grade of hypocalcemia per CTCAE v 4.03, using the 
following formula:  
Corrected calcium = ([4 – serum albumin in g/dL] x 0.8 + serum calcium)  
The formula is not applicable when serum albumin concentration is normal (˃4 g/dL); in 
such situations, the total (uncorrected) serum calcium should be used instead.  
Hypocalcemia should be treated per institutional guidelines (eg, using appropriate calcium, 
magnesium, and Vitamin D supplementation) until resolution. 
9.4.1.13 
Management of Hemorrhage 
For subjects with hemorrhage, either resume at a reduced dose or discontinue study treatment 
depending on the severity and persistence of hemorrhage. 
9.4.1.14 
Management of Gastrointestinal Symptoms and Acute Abdominal Pain 
Initial management of acute abdominal pain in these study subjects should be focused on 
treating the underlying cause where possible, ensuring appropriate hydration/rehydration, and 
symptomatic pain improvement consistent with subject’s age and in accordance to local and 
institutional standards of care.  Appropriate supportive care should be provided together with 
close monitoring. 
For AEs of abdominal pain believed related to lenvatinib or more specific AEs believed 
related to lenvatinib that result in the symptom of abdominal pain, instructions contained in 
Table 5 regarding study treatment dose reduction and interruption instructions.  For Grade 4 
AEs that result in abdominal pain, study treatment must be discontinued. 
Gastrointestinal symptoms including diarrhea should be managed by providing symptomatic 
treatment.  If the symptoms persist (eg, diarrhea for more than 10 days), Study Treatment 
Interruption and Reduction guideline should be followed.  Gastrointestinal symptoms should 
be monitored closely and evaluated using CT, Contrast-Enhanced MRI, ultrasound, or other 
diagnostic imaging if clinically indicated, at the investigator’s discretion.  It is recommended 
that all gastrointestinal symptoms should be recorded in the diary provided.

Management of Fistula Formation and Gastrointestinal Perforation 
Lenvatinib should be discontinued in any subject who develops Grade 4 fistula 
(gastrointestinal or non-gastrointestinal), or gastrointestinal perforation of any grade. 
9.4.1.16 
Management of Osteonecrosis of the Jaw 
Perform an oral examination prior to treatment with lenvatinib and periodically during 
lenvatinib treatment. Advise study subjects regarding good oral hygiene practices. Avoid 
invasive dental procedures, if possible, while on lenvatinib treatment, particularly in study 
subjects at higher risk. For study subjects requiring invasive dental procedures, 
discontinuation of bisphosphonate treatment may reduce the risk of osteonecrosis of the jaw. 
Withhold lenvatinib if osteonecrosis of the jaw develops and restart based on clinical 
judgement of adequate resolution (see Section 9.4.7). 
9.4.1.17 
Management of QT Prolongation 
Lenvatinib should be withheld in the event of development of QT interval prolongation 
greater than 500 msec. Lenvatinib should be resumed at a reduced dose when QTc 
prolongation is resolved to <480 msec or baseline. Monitor potassium, calcium and 
magnesium, and replenish as appropriate. 
9.4.2

calibrated chart recorder, or by manual means, such that minimum and maximum 
thermometric values over a specific time period can be recorded and retrieved as required. 
9.4.3 
Method of Assigning Subjects to Treatment Groups 
This is an open-label, single-arm study.  All subjects who provide signed informed consent to 
participate in this study and satisfy all eligibility requirements (see Section 9.3) will be 
assigned to receive lenvatinib in combination with everolimus in 28-day treatment cycles.  
There is no randomization in this study. 
9.4.4 
Selection of Doses in the Study 
The purpose of the Phase 1 portion of the study is to determine the MTD and the RP2D of 
lenvatinib administered in combination with everolimus in this pediatric population.  The 
dose levels of lenvatinib and everolimus to be evaluated in the study are pre-specified.  The 
starting dose level of lenvatinib is 11 mg/m2, which is approximately 80% of lenvatinib 
single dose MTD in pediatric subjects determined in the ongoing Study E7080-G000-207.  
The initial dose of everolimus is 3 mg/m2, which is 66% of the FDA approved dose and dose 
previously found effective in subependymal giant cell astrocytoma. 
9.4.5 
Selection and Timing of Dose for Each Subject 
Lenvatinib and everolimus are to be administered orally once a day at approximately the 
same time without regard to food intake for 28 days from Cycle 1 onward.  If a subject 
misses a dose of lenvatinib, it may be taken within the 12 hours following the usual time of 
the dose.  If more than 12 hours have elapsed from the time of the usual daily dose, 
lenvatinib should be taken the next day at the usual time.  In the event a subject vomits after 
study drug administration, the subject should not take another dose until the next scheduled 
dose.   
Refer to everolimus prescribing information for recommended everolimus dosing 
information. 
Study drugs should be administered at the clinic on PK sampling days.  All scheduled visits 
must be conducted as per protocol, irrespective of treatment interruption.  If holidays or 
personal schedules make administration impossible on the scheduled days, then 
administration should be resumed as soon as possible.

the course of the study (starting at the date of informed consent) until 28 days after the final 
dose of study drug will be recorded.  Additionally, all diagnostic, therapeutic, or surgical 
procedures relating to malignancy should be recorded.  Any medication that is considered 
necessary for the subject’s health and that is not expected to interfere with the evaluation of 
or interact with the study medication may be continued during the study. 
Aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), and low-molecular-weight heparin 
(LMWH) are permissible but should be used with caution.  Erythropoietic stimulating agents 
(ESAs) may be used according to the American Society of Clinical Oncology (ASCO), 
institutional, or national guidelines and according to the SmPC or local labeling instructions, 
but the subject should be carefully monitored for increases in red blood cell counts.   
Treatment (including blood products, blood transfusions, fluid transfusions, antibiotics, and 
antidiarrheal drugs, etc) of complications of AEs or therapy to ameliorate symptoms may be 
administered at the discretion of the investigator, unless it is expected to interfere with the 
evaluation of (or to interact with) the study medication.  
An anti-diarrheal agent should be recommended to the subject at the start of study treatment 
and subjects should be instructed and educated to initiate anti-diarrheal treatment at the first 
onset of soft bowel movements.  The choice of anti-diarrheal agent should be individualized 
to the subject’s clinical circumstances and follow standard medical practice.  If 
signs/symptoms of diarrhea persist despite optimal medical management, instructions 
contained in the Dose Modification Guidelines should be followed. 
Administration of corticosteroids for progressive disease is not permitted.  Administration of 
corticosteroids will be limited to premedication or the short-term treatment of acute medical 
conditions in accordance with approved indications, institutional, or national guidelines. 
Palliative radiotherapy of up to 2 painful pre-existing, non-target bone metastases will be 
permitted without being considered progressive disease.  In the Phase 1 part, palliative 
radiotherapy will be allowed after the completion of Cycle 1. 
If a subject receiving treatment with lenvatinib requires surgery during the study, the stop 
time and restart time of lenvatinib should be as follows: 
 For minor procedures:  stop lenvatinib at least 2 days before the procedure and restart it 
at least 2 days after, once there is evidence of adequate healing and no risk of bleeding.  
 For major procedures:  stop lenvatinib at least 1 week (5 half-lives) prior to surgery and 
then restart it at least 1 week after, once there is evidence of adequate healing and no 
risk of bleeding. 
 For scheduled dental surgery or invasive dental procedures: stop lenvatinib for at least 
1 week before the procedure, then restart lenvatinib when deemed clinically 
appropriate. 
If concomitant medication/therapy is administered for an AE, investigators will record that 
AE on the Adverse Events CRF.

9.4.7.1 
Drug-Drug Interactions 
Lenvatinib’s weak in vitro inhibitory and induction potential on CYP enzymes 
(Study No. XT063020) suggests a low risk of lenvatinib interference with the PK of other 
drugs metabolized by CYP enzymes which are co-administered in usual clinical practice.  
Nonclinical studies identify CYP3A4 as the important CYP isozyme responsible for human 
hepatic metabolism of lenvatinib.  However, clinical studies conducted showed that 
coadministration of lenvatinib with CYP3A4/P-gp inhibitors or inducers is not of clinical 
concern.  The main metabolic pathways for lenvatinib in humans were identified as 
enzymatic (CYP3A and aldehyde oxidase) and non-enzymatic processes (Lenvima® package 
insert).   
For subjects receiving everolimus, drugs or substances (including herbal supplements or 
grapefruit juice) known to be potent inhibitors of CYP3A4/P-gp should not be used.  Potent 
inducers of CYP3A4/P-gp should not be used unless there is no alternative treatment 
available.  Dose increase of everolimus may be considered when co-administering strong 
CYP3A4 or P-gp inducers.  Moderate/ weak inhibitors or inducers or substrates of CYP3A4 
and/or P-gp should be used with caution.  Dose reduction of everolimus may be considered 
when co-administering moderate CYP3A4 or P-gp inhibitors.  For further information, please 
refer to everolimus prescribing information. 
9.4.7.2 
Prohibited Concomitant Therapies and Drugs 
Subjects are prohibited from receiving the following therapies during the Screening and 
Treatment Phase of this study: 
 
Concurrent anticancer therapies such as chemotherapy, TKIs, radiotherapy (with the 
exception of palliative radiotherapy as specified in Section 9.4.7), antitumor interventions 
(surgical resection, surgical debulking of tumor, etc), or cancer immunotherapy 
 
Concurrent other investigational drugs 
 
Live vaccines are prohibited while participating in the study.  Examples of live vaccines 
include, but are not limited to, the following: measles, mumps, rubella, chicken pox, 
yellow fever, rabies, BCG, and typhoid (oral) vaccine.  Seasonal influenza vaccines for 
injection are generally killed virus vaccines and are allowed.  However intranasal 
influenza vaccines (eg, Flu-Mist®) are live attenuated vaccines, and are not allowed. 
For subjects who, in the assessment by the investigator, require the use of any of the 
aforementioned treatments for clinical management, continuation of the study medication 
and further participation in the study must be discussed and agreed upon with the sponsor. 
If subjects receive additional anticancer therapies, this will be judged to represent evidence of 
disease progression, and study medication will be discontinued.  These subjects should 
complete all off-treatment assessments and continue to be followed for survival in the 
Follow-Up Period.

Efficacy Assessments 
9.5.1.3.1 TUMOR ASSESSMENTS 
For all tumor types except HGG:  Tumor assessments will be performed using RECIST 1.1 
(Appendix 1).  Investigator-determined response assessments will be performed at each 
assessment time point and entered onto the CRF.  Tumor assessments (CT chest and CT/MRI 
of abdomen, pelvis and other areas of known disease at screening plus any areas of suspected 
disease) should be performed at Screening and, for Phase 1 of the study, at Week 4 ±1 week, 
Week 12 ±1 week, Week 24 ±1 week, and every 12 weeks ±1 week thereafter, or as 
clinically indicated.  For subjects with primary CNS tumors and no other known areas of 
disease only target and non-target lesions plus any areas of newly suspected disease must be 
scanned.  For Phase 2 of the study, tumor assessments should be performed at Screening, 
Week 8 ±1 week, Week 16 ±1 week, Week 24 ±1 week, and then every 12 weeks ±1 week 
thereafter, or as clinically indicated.  All responses are to be confirmed at a follow-up 
examination after ≥28 days following the initial indication of response.  Historical scans 
(within 28 days prior) that do not follow the guidelines completely may be used.  
A brain scan (CT with contrast or MRI pre- and post-contrast) will be performed at 
Screening and during the study if clinically indicated. 
For Phase 1 of the study, subsequent tumor assessments will occur at Week 4 ±1 week, 
Week 12 ±1 week, Week 24 ±1 week and every 12 weeks ±1 week thereafter, or as clinically 
indicated.  For Phase 2 of the study, tumor assessments should be performed at Week 8 ±1

week, Week 16 ±1 week, Week 24 ±1 week, and then every 12 weeks ±1 week thereafter, or 
as clinically indicated.  Tumor assessments will be performed based on RECIST 1.1 
beginning from the date of first dose, continuing during treatment cycles until documentation 
of disease progression.  This schedule for tumor assessments will be maintained irrespective 
of treatment delays.  All responses are to be confirmed at a follow-up examination after ≥28 
days following the initial indication of response.  The same methodology (CT or MRI) and 
scan acquisition techniques (including use or nonuse of intravenous contrast) as was used for 
the Screening assessments should be utilized across all time points to allow consistent 
comparison of lesions.  After treatment discontinuation for a reason other than disease 
progression, tumor assessments should continue to be performed every 12 weeks until 
documentation of progression or start of a new anticancer agent.  Please see Appendix 13 for 
imaging methodology for tumor assessment. 
If protocol eligible brain metastases are present at Screening, a CT/MRI of the brain must be 
performed at all tumor assessment time points.  
For HGG:  Tumor assessments will be performed using RANO Criteria (Appendix 14).  A 
standard MRI-imaging protocol will be performed for use in the assessments.  
Investigator-determined response assessments at each assessment time point will be entered 
onto the appropriate CRFs.  Tumor assessments will be carried out during Screening and for 
Phase 1 of the study, at Week 4 ±1 week, Week 12 ±1 week, Week 24 ±1 week, and then 
every 12 weeks ±1 week thereafter, or as clinically indicated.  For Phase 2 of the study, 
tumor assessments should be performed at Screening, Week 8 ±1 week, Week 16 ±1 week, 
Week 24 ±1 week, and every 12 weeks ±1 week thereafter, or as clinically indicated. 
For Phase 2, copies of scans for tumor assessments will be sent to an imaging core laboratory 
designated by the sponsor for quality assessment and archival and potential future 
independent review.  
After data cutoff, tumor assessments may be performed as clinically indicated as per the 
institutional guidelines, following the prevailing local standard of care and scans will not be 
sent to the imaging core laboratory. 
The imaging methodology for tumor assessments for all tumor types, including solid tumors 
and HGG, is provided in Appendix 13.

9.5.1.4.2 PHARMACODYNAMIC, PHARMACOKINETIC/PHARMACODYNAMIC, PHARMACOGENOMIC, 
AND OTHER BIOMARKER, ASSESSMENTS 
Pharmacodynamic Assessments:  Blood samples for plasma and serum studies will be 
collected from consenting subjects (optional) at Baseline and on Cycle 1 Day 15, Cycle 2 
Day 1, and then matched with tumor assessments and at the Off-treatment Visit, as specified 
in the Schedule of Assessments (Table 7 and Table 8).  Only subjects with BSA >0.68 m2 are 
eligible to consent (optional) to blood samples for plasma and serum studies.  Biomarker 
discovery and/or validation will be performed to identify blood or tumor biomarkers that may 
be useful to predict subject response to study drug as well as for potential use in diagnostic 
development (see Appendix 11).  Blood samples may undergo global proteomic and/or single 
analyte enzyme-linked immunosorbent assays (ELISA) or multiplex immunoassays based on 
the amount of sample available.  Potential blood biomarkers to be explored include FGF 
ligands (eg, FGF2/bFGF, FGF19, FGF21, FGF23), and angiogenesis related markers (eg, 
VEGF, Ang 1/2, sTie-2, HGF, PlGF).  In addition, biomarkers identified in other lenvatinib 
clinical studies may also be assessed in samples collected from subjects enrolled in this 
study.  The decision to perform exploratory biomarker analysis may be based on the clinical 
outcome of this study and/or the signals observed in other clinical studies or other 
information available at that time. 
Pharmocokinetic/Pharmacodynamic Assessments: Relationships between lenvatinib 
exposure and safety will be explored graphically.  Pending the outcome of graphical 
assessments, modeling of potential relationships will be explored.  Details of exposure-safety 
analyses will be provided in a separate analysis plan. 
Pharmacogenomic/Pharmacogenetic Assessments:  Archived, fixed tumor tissue will be 
collected (if available), as specified in the Schedule of Assessments (Table 7 and Table 8), 
for potential assessment of mutations and other genetic alterations in genes and/or proteins 
that may be important in the development and progression of tumor biology relevant to the 
tumor types being explored, to evaluate response to study drug treatment, as well as for 
potential use in diagnostic development.  Genetic alterations in target genes include 
lenvatinib targets (eg, FGF ligands and FGF receptors 1-4), angiogenesis-relevant targets 
(such as expression levels of VEGF, Ang 1/2, Tie-2, HGF and cMET) and markers 
associated with cell differentiation and tumorigenesis (eg, WNT/β-catenin pathway, 
hedgehog/PTCH pathway, and BMP/TGF signaling pathway).  Appropriate analytical 
technology/methodologies, such as next generation sequencing (NGS)-based whole exome 
sequencing (WES), whole transcriptome analysis or targeted re-sequencing using targeted 
gene panels (eg, ThermoFisher Oncomine Comprehensive Assay (OCA)) for gene 
alterations, targeted gene expression panels (eg, Nanostring PanCancer Pathway, PanCancer 
Immune) for gene expression analysis, single analyte or multiplex IHC, etc may be used 
based on the amount of tumor tissue available.

Blood plasma samples will be collected (optional) for analysis of cell-free nucleic acid 
(cf-nucleic acid).  Cell-free nucleic acid isolated from plasma samples may be used to 
explore tumor genetic alterations such as mutations and other genetic alterations observed in 
archival tumor samples (using NGS-based targeted gene panels), as well as those which 
develop during drug treatment to monitor response to study drug.   
A blood sample will be collected for PG analysis (optional).  Variation in study drug 
exposure or the occurrence of AEs observed in the study population may be evaluated by 
correlating single–nucleotide polymorphisms with PK, safety, or PD data.  Genomic DNA 
extracted from blood samples may be used to confirm whether the DNA sequence variants 
observed in DNA extracted from tumor material are limited to the tumor. 
Data obtained will be used for research to assist in developing safer and more effective 
treatments and will not be used to change the diagnosis of the subject or alter the therapy of 
the subject.  The PD and PG samples will not be used to determine or predict risks for 
diseases that an individual subject does not currently have.  Any sample or derivatives (DNA, 
RNA, and protein) may be stored for up to 15 years after study completion to assist in 
research scientific questions related to cancer biology or for potential diagnostic 
development. 
Instructions for the processing, storage, and shipping of samples will be provided in the 
Laboratory Instruction Manual. 
9.5.1.5 
Safety Assessments 
Safety assessments will consist of monitoring and recording all AEs and serious adverse 
events (SAEs) using CTCAE v4.03; regular laboratory evaluation for hematology, blood 
chemistry, and urine dipstick values; regular performance of physical examinations; periodic 
measurement of vital signs, 12-lead ECGs, echocardiography/MUGA scan, Lansky play 
score and Karnofsky performance score as detailed in the Schedule of Assessments (Table 7 
and Table 8).   
BP monitoring will occur at least weekly during the first 2 cycles.  BP will be assessed in 
terms of percentile for sex, age and height/length.  Antihypertensive agents should be started 
as soon as elevated BP (systolic BP ≥95th percentile [BP ≥140 mmHg for adult subjects] or 
diastolic BP ≥95th percentile [BP ≥90 mmHg for adult subjects]) is confirmed on 
2 assessments obtained 1 hour apart.  For subjects with hypertension and proteinuria, 
treatment with an angiotensin-converting enzyme (ACE) inhibitor or angiotensin-II receptor 
antagonist is preferred.  Cardiac systolic function and QTc will be assessed at screening, 
prior to Cycles 2 and 5, and every sixth cycle thereafter by echocardiography/MUGA scan 
and electrocardiogram.  
9.5.1.5.1 ADVERSE EVENTS  
An AE is any untoward medical occurrence in a patient or clinical investigation subject 
administered an investigational product.  An AE does not necessarily have a causal

relationship with the medicinal product.  For this study, the study drugs are lenvatinib and 
everolimus.  
The criteria for identifying AEs in this study are: 
 
Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of an investigational product, 
whether or not considered related to the investigational product (Note:  Every sign or 
symptom should not be listed as a separate AE if the applicable disease [diagnosis] is 
being reported as an AE) 
 
Any new disease or exacerbation of an existing disease.  However, worsening of the 
primary disease should be captured under efficacy assessments as disease progression 
rather than as an AE. 
 
Any deterioration in nonprotocol-required measurements of a laboratory value or other 
clinical test (eg, ECG or x-ray) that results in symptoms, a change in treatment, or 
discontinuation of study drug 
 
Recurrence of an intermittent medical condition (eg, headache) not present pretreatment 
(Baseline) 
 
An abnormal laboratory test result should be considered an AE if the identified laboratory 
abnormality leads to any type of intervention, withdrawal of study drug, or withholding 
of study drug, whether prescribed in the protocol or not. 
All AEs observed during the study will be reported on the CRF.  All AEs, regardless of 
relationship to study drug or procedure, should be collected beginning from the time the 
subject signs the study ICF through the last visit and for 28 days after the last dose of study 
treatment.  Serious AEs (SAEs) will be collected for 28 days after the last dose of study 
treatment. 
Abnormal laboratory values should not be listed as separate AEs if they are considered to be 
part of the clinical syndrome that is being reported as an AE.  It is the responsibility of the 
investigator to review all laboratory findings in all subjects and determine if they constitute 
an AE.  Medical and scientific judgment should be exercised in deciding whether an isolated 
laboratory abnormality should be classified as an AE.  Any laboratory abnormality 
considered to constitute an AE should be reported on the Adverse Event CRF.  
Abnormal ECG (corrected QT interval [QTc]) results, if not otherwise considered part of a 
clinical symptom that is being reported as an AE, should be considered an AE if the QTc 
interval is more than 450 msec and there is an increase of more than 60 msec from baseline.  
Any ECG abnormality that the investigator considers as an AE should be reported as such. 
All AEs must be followed for 28 days after the subject’s last dose, or until resolution, 
whichever comes first.  All SAEs must be followed to resolution or, if resolution is unlikely, 
to stabilization.   
Every effort must be made by the investigator to categorize each AE according to its 
severity and its relationship to the study treatment.

Assessing Severity of Adverse Events 
The criteria for assessing severity are different than those used for seriousness (see 
Section 9.5.1.5.2 for the definition of an SAE). 
Adverse events will be graded on a 5-point scale according to CTCAE v4.03 (Appendix 2).  
Investigators will report CTCAE grades for all AEs.  
Assessing Relationship to Study Treatment 
Items to be considered when assessing the relationship of an AE to the study treatment are: 
 
Temporal relationship of the onset of the event to the initiation of the study treatment 
 
The course of the event, especially the effect of discontinuation of study treatment or 
reintroduction of study treatment, as applicable 
 
Whether the event is known to be associated with the study treatment or with other 
similar treatments 
 
The presence of risk factors in the study subject known to increase the occurrence of the 
event 
 
The presence of nonstudy, treatment-related factors that are known to be associated with 
the occurrence of the event 
Classification of Causality 
The relationship of each AE to the study drug will be recorded on the CRF in response to the 
following question: 
Is there a reasonable possibility that the study drug caused the AE? 
Yes (related) 
A causal relationship between the study drug and the AE is a reasonable 
possibility. 
No (not related) A causal relationship between the study drug and the AE is not a 
reasonable possibility. 
9.5.1.5.2 SERIOUS ADVERSE EVENTS AND EVENTS ASSOCIATED WITH SPECIAL SITUATIONS 
SAE is any untoward medical occurrence that at any dose: 
 
Results in death 
 
Is life-threatening (ie, the subject was at immediate risk of death from the AE as it 
occurred; this does not include an event that, had it occurred in a more severe form or 
was allowed to continue, might have caused death) 
 
Requires inpatient hospitalization or prolongation of existing hospitalization 
 
Results in persistent or significant disability/incapacity 
 
Is a congenital anomaly/birth defect (in the child of a subject who was exposed to the 
study drug)

Other important medical events that may not be immediately life-threatening or result in 
death or hospitalization but, when based on appropriate medical judgment, may jeopardize 
the subject or may require intervention to prevent one of the outcomes in the definition of 
SAE listed above should also be considered SAEs.  Medical and scientific judgment should 
be exercised in deciding whether expedited reporting is appropriate in such situations.  In 
addition to the above, events associated with special situations include pregnancy or 
exposure to study drug through breastfeeding, AEs associated with study drug overdose, 
misuse, abuse, or medication error.  These events associated with special situations are to be 
captured using the SAE procedures but are to be considered as SAEs only if they meet one of 
the above criteria.  All AEs associated with special situations are to be reported on the CRF 
whether or not they meet the criteria for SAEs.   
All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization. 
The following hospitalizations are not considered to be SAEs because there is no “adverse 
event” (ie, there is no untoward medical occurrence) associated with the hospitalization: 
 
Hospitalizations for respite care  
 
Planned hospitalizations required by the protocol 
 
Hospitalization planned before informed consent (where the condition requiring the 
hospitalization has not changed after study drug administration) 
 
Hospitalization for administration of study drug or insertion of access for administration 
of study drug 
 
Hospitalization for routine maintenance of a device (eg, battery replacement) that was in 
place before study entry 
9.5.1.5.3 LABORATORY MEASUREMENTS 
Clinical laboratory tests to be performed, including hematology, chemistry, and urinalysis, 
are summarized in Table 6.  Subjects should be in a seated or supine position during blood

b:  Direct bilirubin should be assessed if total bilirubin is elevated. 
c:  Thyroid function will be assessed every cycle  
d:  For subjects with blood glucose>ULN, a fasting (>6h, water only) blood glucose sample will be obtained. 
e:  If urine dipstick testing suggests a urinary tract infection, or if clinically indicated, a urine microscopy, culture, and 
sensitivity should be performed at the institution’s laboratory.  If urine protein is ≥2+, then a spot test for protein-creatinine 
ratio and if possible, a 24-hour urine collection should be done to quantify the 24 hour urine protein excretion.  
 
All clinical laboratory tests during the study will be performed by local laboratories.  All 
hematology, blood chemistry (including pregnancy test, as applicable), and urinalysis 
samples are to be obtained prior to study drug administration and sent to the local laboratory 
on the day of collection, unless otherwise instructed.  
All hematology, blood chemistry (including pregnancy test, as applicable), and urinalysis 
samples are to be obtained prior to study drug administration and results reviewed prior to 
administration of study drug on Cycle 1 Day 1 and within 48 hours prior to dispensing study 
drug for all subsequent cycles.  If ≥Grade 3 hematologic or clinical chemistry toxicity, repeat 
laboratory test and AEs assessment at least every 3 days (until improvement to <Grade 3).  
Refer to Table 5 for the management of clinically significant laboratory abnormalities. 
A laboratory abnormality may meet the criteria to qualify as an AE as described in this 
protocol (see Section 9.5.1.5.1 and the CRF Completion Guidelines).  In these instances, the 
AE corresponding to the laboratory abnormality will be recorded on the Adverse Event CRF.

For laboratory abnormalities meeting the criteria of SAEs (Section 9.5.1.5.2), the site must 
send the SAE report including the laboratory report (as regionally required) to the SAE fax 
number or email provided in the Investigator File. 
9.5.1.5.4 VITAL SIGNS AND WEIGHT MEASUREMENTS 
Vital sign measurements (ie, systolic and diastolic BP [mmHg], pulse rate [beats per minute], 
respiratory rate [per minute], body temperature [in centigrade]), and weight (kg) and height 
(cm) will be obtained at the visits designated in the Schedule of Assessments (Table 7 and 
Table 8) by a validated method.  BP and pulse rate will be measured after the subject has 
been resting for 5 minutes.  All BP measurements should be performed on the same arm, 
preferably by the same person.  For subjects with an elevated BP (≥95th percentile for sex, 
age, and height/length) it should be confirmed by 2 assessments obtained 1 hour apart.  One 
BP assessment is defined as the mean value of 3 measurements obtained at least 5 minutes 
apart.  Subjects with elevated BP (≥99th percentile for sex, age and height/length) must have 
their BP monitored every 2 weeks (on Day 15 or more frequently as clinically indicated) 
until BP has been <95th percentile for 3 consecutive months.  If a new event of elevated BP 
occurs, the subject must resume the Day 15 evaluation until BP has been <95th percentile for 
3 consecutive months.  BP that is consistently above the 95th percentile for sex, age, and 
height/length requires further evaluation. 
9.5.1.5.5 PHYSICAL EXAMINATIONS 
Physical examinations will be performed as designated in the Schedule of Assessments 
(Table 7 and Table 8).  Documentation of the physical examination will be included in the 
source documentation at the site.  Only changes from screening physical examination 
findings that meet the definition of an AE will be recorded on the Adverse Events CRF. 
9.5.1.5.6 ELECTROCARDIOGRAMS 
Electrocardiograms will be obtained as designated in the Schedule of Assessments (Table 7 
and Table 8).  Complete, standardized, single 12-lead ECG recordings that permit all 
12 leads to be displayed on a single page with an accompanying Lead II rhythm strip below 
the customary 3 × 4 lead format are to be used.  In addition to a rhythm strip, a minimum of 3 
full complexes should be recorded from each lead simultaneously.  If possible, subjects 
should be in the recumbent position for a period of 5 minutes prior to the ECG. 
An ECG abnormality may meet the criteria of an AE as described in this protocol (see 
Section 9.5.1.5.1) and the CRF Completion Guidelines.  In these instances, the AE 
corresponding to the ECG abnormality will be recorded on the Adverse Events CRF. 
Cardiac systolic function and QTc will be assessed using echocardiography and ECG.  See 
Table 7 and Table 8 for test schedules.

9.5.1.5.7 OTHER SAFETY ASSESSMENTS 
A Lansky play score or Karnofsky performance status score will be obtained at the 
Screening, Baseline, and Cycle 2 Day 1 visits, and every subsequent cycle visit thereafter and 
at the Off-treatment Visit. 
Proximal tibial growth plates x-rays will be taken at baseline and at the Off-treatment Visit 
(for subjects with open plates at the Baseline Visit). 
Information from studies in animals suggest that there is a risk of delayed tooth formation 
and/or physical growth and development.  Therefore, dental examinations are being 
performed to evaluate subjects for potential anomalies in tooth formation and eruption 
schedule. 
A dental examination by a qualified healthcare professional should be conducted per local 
institutional guidelines at baseline (C1D1±4 weeks), and thereafter per local standard of care 
(but no less than annually), and as part of the Off-treatment assessment.  If the most recent 
dental exam is within 6 months prior to the Off-treatment Visit, the dental examination is not 
required.  Postbaseline dental examinations are not required for subjects for whom permanent 
teeth (excluding third molars) are evaluated to be fully erupted at Baseline. 
An echocardiogram to assess left ventricular shortening fraction or echocardiogram/MUGA 
scan to assess left ventricular ejection fraction (LVEF) will be performed during screening, 
Cycle 2 Day 1 (predose), Cycle 5 Day 1 (predose) and every 6th Cycle thereafter (Cycle 11 
Day 1, Cycle 17 Day 1, etc predose each) and at the Off-treatment Visit or sooner if 
clinically indicated. 
9.5.1.6 
Other Assessments 
Pregnancy Test 
A serum β-hCG test will be performed for females of childbearing potential (see definition 
included in the Inclusion/Exclusion criteria).  A serum or urine pregnancy test will be 
performed at Screening and Baseline (or within 72 hours prior to the first dose of study 
treatment), prior to Day 1 of each subsequent cycle and at the Off-treatment Visit in females 
of childbearing potential.  The results must be reviewed prior to administration of study drug 
on Cycle 1 Day 1 and within 48 hours prior to dispensing study drug for all subsequent 
cycles.  Blood and urine samples will be taken at designated time points as specified in the 
Schedule of Assessments (Table 7 and Table 8).

1 hour postdose.  With the exception of the predose samples on Cycle 1 Day 1, all other predose samples are to be drawn at 24 hour post dose administered on the previous 
day.  If dose interruption is necessary at these time points, please contact the sponsor. 
o. For all tumor types except HGG, Screening:  Tumor assessments using CT chest and CT/MRI of the abdomen, pelvis, and other areas of known disease or newly suspected 
disease should be performed within 28 days prior to C1D1.  Scans of the abdomen, pelvis, and other areas of the body may be done with MRI instead of CT, but evaluation of 
the chest should be done with CT.  During the Treatment Phase tumor assessments using CT chest and CT/MRI of the abdomen, pelvis, and other areas of known disease or 
newly suspected disease should be performed at Week 4 ±1 week, and in the Extension Phase at Week 12 ±1 week, Week 24 ±1 week and every 12 weeks ±1 week thereafter 
or as clinically indicated.  For subjects with primary CNS tumors and no other known areas of disease only target and non-target lesions plus any areas of newly suspected 
disease must be scanned.  All responses are to be confirmed at a follow-up examination after ≥28 days following the initial indication of response.  Scans should be performed 
using the same methodology (CT or MRI) and scan acquisition techniques (including use or nonuse of IV contrast) as was used for the screening assessments.  Tumor response 
will be assessed according to RECIST 1.1.  All responses should be confirmed at a follow-up examination after ≥28 days. 
p. Brain CT with contrast or MRI pre- and post- gadolinium contrast will be performed at Screening, and if clinically indicated. 
q. For HGG, RANO criteria will be followed, Screening:  Tumor assessments using MRI of the brain that will be followed as target lesions and non-target lesions should be 
performed within 28 days prior to the C1D1.  During the Treatment Phase tumor assessments of the same brain lesions as at Screening, should be performed at Week 4 
±1 week, and in the Extension Phase at Week 12 ±1 week, Week 24 ±1 week and every 12 weeks ±1 week thereafter, or as clinically indicated.  All responses should be 
confirmed at a follow-up examination after ≥28 days following the initial indication of response.  The same methodology (MRI) and scan acquisition techniques (including use 
or nonuse of IV contrast) should be used as was used for the screening assessments. 
r. Proximal tibial growth plates x-rays should be conducted at Baseline and at the Off-treatment visit (for subjects with open plates at the baseline visit).  A dental examination 
by a qualified healthcare professional should be conducted per local institutional guidelines at baseline (C1D1±4 weeks), and thereafter per local standard of care (but no less 
than annually) and as part of the Off-treatment assessment.  If the most recent dental examination is within 6 months prior to the Off-treatment Visit, the dental exam is not 
required. Post-baseline dental exams are not required for subjects for whom permanent teeth (excluding third molars) are evaluated to be fully erupted at baseline. 
s. Blood samples will be collected from consenting subjects (optional) for plasma and serum at Baseline, and predose on Cycle 1 Day15, Cycle 2 Day 1, and then matched with 
tumor assessments, and at the Off-treatment Visit.  Only subjects with BSA >0.68 m2 are eligible to consent (optional) to blood samples for plasma and serum studies.  Serum 
sample will be used for evaluating biomarkers of response and plasma sample for cf-nucleic acid to explore proteins and genetic alterations in genes implicated in angiogenesis.

to 4 weeks prior to C1D1. 
c. Baseline assessments can be performed on Day -1 or on C1D1 prior to treatment. 
d. Duration of Treatment Phase: 4 Cycles (Visit 3-15); Duration of Extension Phase Cycle 5 – Last (Visit 16 – Last).  Subjects benefiting from study treatment in the opinion of 
the investigator will continue treatment until disease progression, development of unacceptable toxicity, or protocol off study criteria are met, whichever occurs first.   
e. Subjects will be followed every 3 months for 1 year or until death whichever occurs first, as per the protocol. 
f. A serum or urine pregnancy test will be performed at the Screening and Baseline Visits (or within 72 hours prior to the first dose of study medication), prior to Day 1 of each 
subsequent cycle and at the off-treatment visit in females of childbearing potential. The results must be reviewed prior to administration of study drug on Cycle 1 Day 1 and 
within 48 hours prior to dispensing study drug for all subsequent cycles. 
g. A Lansky play score or Karnofsky performance status score will be obtained at the Screening, Baseline, and Cycle 2 Day 1 visits, and every subsequent cycle visit in the 
Treatment Phase and Extension Phase thereafter and at the Off-treatment Visit. 
h. A comprehensive physical examination (including a neurological examination) will be performed at the Screening and Baseline Visits (only if screening physical examination 
was performed >7 days prior to C1D1), C1D15, Day 1 visit of each subsequent cycle in the Treatment Phase and Extension Phase, and at the Off-treatment Visit.  A 
symptom-directed physical examination will be performed on C1D1 and at any time during the study, as clinically indicated. 
i. Assessments will include vital signs (resting BP, HR, RR, and body temperature, and weight).  Height measurement will be obtained at Baseline Visit, at C4D1 and thereafter at 
D1 of every third cycle.  Blood pressure that is consistently above the 95th percentile for sex, age, and height/length requires further evaluation.  For blood pressure 
management, please refer to in the protocol.  Blood pressure (BP) monitoring will occur at least weekly during the first 2 cycles. 
j. Single 12-lead ECG.  If possible, the subject should be in the recumbent position for a period of 5 minutes prior to the ECG.  It should be performed at screening, Cycle 2 Day 
1 (predose) in the Treatment Phase, and at Cycle 5 Day 1 (predose) and every 6th Cycle thereafter (C11D1, C17D1, etc predose each) in the Extension Phase, and at the Off-
treatment visit.  
k. An echocardiogram/MUGA scan will be performed during screening, Cycle 2 Day 1 (predose) in the Treatment Phase, and at Cycle 5 Day 1 (predose) and every 6th Cycle 
thereafter (C11D1, C17D1, etc predose each) in the Extension Phase, and at the Off-treatment Visit or sooner if clinically indicated.  The assessments may be performed within 
1 week prior to Day 1 of each scheduled cycle. 
l. Clinical chemistry and hematology results must be reviewed prior to administration of study drug on C1D1 and within 48 hours prior to dispensing study drug for all 
subsequent cycles in the Treatment Phase and Extension Phase.  Scheduled assessments may be performed within 72 hours prior to the visit.  If ≥Grade 3 hematologic or 
clinical chemistry toxicity, repeat laboratory test and AEs assessment at least every 3 days (until improvement to <Grade 3).   
m. Urine dipstick testing should be performed at screening and on Day 1, 8, 15 and 22 for Cycles 1-2 in the Treatment Phase, bi-weekly thereafter or more frequently in the 
Treatment Phase and Extension Phase as clinically indicated and at the Off-treatment Visit.  For subjects with history of proteinuria ≥2+, and management of proteinuria please 
refer to the protocol.  Subjects who have ≥2+ proteinuria on dipstick urinalysis should perform a spot P/C test and if possible undergo a 24-hour urine collection.  Urine glucose 
should be performed as part of urine dipstick.  
n. Sparse sampling (two 2 mL samples [total 4 mL blood] per time point) for PK analysis of lenvatinib and everolimus will be performed in the Treatment Phase during Cycle 1 
Day 1 at 0.5-4 hours and 6-10 hours postdose and on Cycle 1 Day15 at predose and 0.5-4 hours and 6-10 hours postdose and on Cycles 2 and 3 predose.  With the exception of 
the predose samples on Cycle 1 Day 1, all other predose samples are to be drawn at 24 hour post dose administered on the previous day.  If dose interruption is necessary at 
these time points, please contact the sponsor. 
o. For all tumor types except HGG, Screening:  Tumor assessments using CT chest and CT/MRI of the abdomen, pelvis, and other areas of known disease or newly suspected 
disease should be performed within 28 days prior to C1D1.  Scans of the abdomen, pelvis, and other areas of the body may be done with MRI instead of CT, but evaluation of 
the chest should be done with CT.  In the Treatment Phase tumor assessments using CT chest and CT/MRI of the abdomen, pelvis, and other areas of known disease or newly 
suspected disease should be performed at Week 8 ±1 week and Week 16 ±1 week, and in the Extension Phase at Week 24 ±1 week, and then every 12 weeks ± 1 week 
thereafter or as clinically indicated.  All responses are to be confirmed at a follow-up examination after ≥28 days following the initial indication of response.  Scans should be 
performed using the same methodology (CT or MRI) and scan acquisition techniques (including use or nonuse of IV contrast) as was used for the screening assessments.  
Tumor response will be assessed according to RECIST 1.1.  All responses should be confirmed at a follow-up examination after ≥28 days. 
p. Brain CT with contrast or MRI pre- and post-gadolinium contrast will be performed at Screening, and if clinically indicated.

q. For HGG, RANO criteria will be followed, Screening: Tumor assessments using MRI of the brain that will be followed as target lesions and non-target lesions should be 
performed within 28 days prior to the C1D1.  In the Treatment Phase tumor assessments of the same brain lesions as at Screening, should be performed at Week 8 ±1 week 
and Week 16 ±1 week, and in the Extension Phase at Week 24 ±1 week and every 12 weeks ±1 week thereafter, or as clinically indicated.  All responses should be confirmed 
at a follow-up examination after ≥28 days following the initial indication of response.  The same methodology (MRI) and scan acquisition techniques (including use or nonuse 
of IV contrast) should be used as was used for the screening assessments. 
r. Proximal tibial growth plates x-rays should be conducted at Baseline and at the Off-treatment visit (for subjects with open plates at the Baseline Visit).  A dental examination 
by a qualified healthcare professional should be conducted per local institutional guidelines at baseline (C1D1±4 weeks), and thereafter per local standard of care (but no less 
than annually), and as part of the Off-treatment assessment.  If the most recent dental examination is within 6 months prior to the Off-treatment Visit, the dental exam is not 
required. Post-baseline dental exams are not required for subjects for whom permanent teeth (excluding third molars) are evaluated to be fully erupted at baseline.  
s. Blood samples will be collected from consenting subjects (optional) for plasma and serum at Baseline, and predose on Cycle 1 Day15, Cycle 2 Day 1, and then matched with 
tumor assessments, and at the Off-treatment Visit.  Only subjects with BSA >0.68 m2 are eligible to consent (optional) to blood samples for plasma and serum studies.  Serum 
sample will be used for evaluating biomarkers of response and plasma sample for cf-nucleic acid to explore proteins and genetic alterations in genes implicated in angiogenesis.  
t. An archival tumor sample from the most recent surgery or biopsy for identification of predictive biomarkers will be collected (if available) from all enrolled subjects at any 
time during the study. 
u. Collection of whole blood to obtain genomic DNA will be performed at the Baseline Visit.  If sampling is not performed predose, sampling may occur at any subsequent visit 
in which other blood sampling is scheduled to occur.  Pharmacogenomic markers of drug metabolism and drug transport may be assessed. 
v. Concomitant medications will be recorded throughout the study and for 28 days after last dose.  All anticancer therapy will be recorded until time of death or termination of 
survival follow-up. 
w. AEs will be recorded from the date of signed informed consent, throughout the study, and for 28 days after last dose.  SAEs irrespective of relationship to study treatment must 
be reported as soon as possible but not later than 24 hours. 
x. The off-treatment assessments should occur within 28 days of the final dose of study treatment.

Description of Procedures/Assessments Schedule 
Please refer to the Schedule of Procedures/Assessments (Table 7 and Table 8). 
9.5.3 
Appropriateness of Measurements 
All clinical assessments are standard measurements commonly used in studies of solid 
tumors. 
The safety assessments to be performed in this study, including hematology analyses, blood 
chemistry tests, urinalysis, ECGs/echocardiograms, and assessment of AEs, are standard 
evaluations to ensure subject safety.  The use of RECIST 1.1 for tumor assessments of solid 
tumors is widely accepted (see Appendix 1) (Eisenhauer, et al., 2009). 
9.5.4 
Reporting of Serious Adverse Events, Pregnancy, and Events Associated 
with Special Situations 
9.5.4.1 
Reporting of Serious Adverse Events 
All SERIOUS ADVERSE EVENTS, regardless of their relationship to study treatment, 
must be reported on a completed SAE form by email or fax as soon as possible but no 
later than 1 business day (or 24 hours for EU sites) from the date the investigator 
becomes aware of the event. 
Serious adverse events, regardless of causality assessment, must be collected through the last 
visit.  All SAEs must be followed to resolution or, if resolution is unlikely, to stabilization.  
Any SAE judged by the investigator to be related to the study treatment or any 
protocol-required procedure should be reported to the sponsor regardless of the length of 
time that has passed since study completion. 
The detailed contact information for reporting of SAEs is provided in the Investigator 
Study File. 
For urgent safety issues, please ensure all appropriate medical care is administered to the 
subject and contact the appropriate study team member listed in the Investigator Study 
File. 
It is very important that the SAE report form be filled out as completely as possible at the 
time of the initial report.  This includes the investigator’s assessment of causality. 
Any follow-up information received on SAEs should be forwarded within 1 business day of 
its receipt.  If the follow-up information changes the investigator’s assessment of causality, 
this should also be noted on the follow-up SAE form. 
Preliminary SAE reports should be followed as soon as possible by detailed descriptions 
including copies of hospital case reports, autopsy reports, and other documents requested by 
the sponsor.

The investigator must notify his/her IRB/IEC of the occurrence of the SAE in writing, if 
required by their institution.  A copy of this communication must be forwarded to the sponsor 
to be filed in the sponsor’s Trial Master File. 
9.5.4.2 
Reporting of Pregnancy and Exposure to Study Drug Through Breastfeeding 
Any pregnancy in which the estimated date of conception is either before the last visit or 
within 28 days of last study treatment, or any exposure to study drug through breastfeeding 
during study treatment or within 28 days of last study treatment, must be reported.  
If an adverse outcome of a pregnancy is suspected to be related to study drug exposure, this 
should be reported regardless of the length of time that has passed since the exposure to study 
treatment. 
A congenital anomaly, death during perinatal period, an induced abortion, or a spontaneous 
abortion are considered to be an SAE and should be reported in the same time frame and in 
the same format as all other SAEs (see Reporting of Serious Adverse Events 
[Section 9.5.4.1]). 
Pregnancies or exposure to study drug through breastfeeding must be reported by fax or 
email as soon as possible but no later than 1 business day from the date the investigator 
becomes aware of the pregnancy.  The contact information for the reporting of pregnancies 
and exposure to study drug through breastfeeding is provided in the Investigator Study File.  
The Pregnancy Report Form must be used for reporting.  All pregnancies must be followed to 
outcome.  The outcome of the pregnancy must be reported as soon as possible but no later 
than 1 business day from the date the investigator becomes aware of the outcome. 
A subject who becomes pregnant must be withdrawn from the study.  
9.5.4.3 
Reporting of Events Associated with Special Situations 
9.5.4.3.1 REPORTING OF ADVERSE EVENTS ASSOCIATED WITH STUDY DRUG OVERDOSE, 
MISUSE, ABUSE, OR MEDICATION ERROR 
Adverse events associated with study drug overdose, misuse, abuse, and medication error 
refer to AEs associated with uses of the study drug outside of that specified by the protocol.  
Overdose, misuse, abuse, and medication error are defined as follows:  
Overdose 
Accidental or intentional use of the study drug in an amount higher 
than the protocol-defined dose  
Misuse 
Intentional and inappropriate use of study drug not in accordance with 
the protocol  
Abuse 
Sporadic or persistent intentional excessive use of study drug 
accompanied by harmful physical or psychological effects

Medication error 
Any unintentional event that causes or leads to inappropriate study 
drug use or subject harm while the study drug is in the control of site 
personnel or the subject.   
All AEs associated with overdose, misuse, abuse, or medication error should be captured on 
the Adverse Event CRF and also reported using the procedures detailed in Reporting of 
Serious Adverse Events (Section 9.5.4.1) even if the AEs do not meet serious criteria.  Abuse 
is always to be captured as an AE.  If the AE associated with an overdose, misuse, abuse, or 
medication error does not meet serious criteria, it must still be reported using the SAE form 
and in an expedited manner but should be noted as nonserious on the SAE form and the 
Adverse Event CRF.  
9.5.4.4 
Expedited Reporting 
The sponsor must inform investigators and regulatory authorities of reportable events, in 
compliance with applicable regulatory requirements, on an expedited basis (ie, within 
specific time frames).  For this reason, it is imperative that sites provide complete SAE 
information in the manner described above. 
9.5.4.5 
Breaking the Blind 
Not applicable 
9.5.4.6 
Regulatory Reporting of Adverse Events 
Adverse events will be reported by the sponsor or a third party acting on behalf of the 
sponsor to regulatory authorities in compliance with local and regional law and established 
guidance.  The format of these reports will be dictated by the local and regional 
requirements. 
All studies that are conducted within any European country will comply with European Good 
Clinical Practice Directive 2005/28/EC and Clinical Trial Directive 2001/20/EC.  All 
suspected unexpected serious adverse reactions (SUSARs) will be reported, as required, to 
the competent authorities of all involved European member states. 
9.5.5 
Completion/Discontinuation of Subjects 
A subject (or subject’s parent or guardian) may elect to discontinue the study at any time for 
any reason.  All subjects who discontinue the study are to complete the study’s early 
discontinuation procedures indicated in the Schedule of Procedures/Assessments (Table 7 
and Table 8). 
The investigator will promptly explain to the subject involved that the study will be 
discontinued for that subject and provide appropriate medical treatment and other necessary 
measures for the subject.  A subject who has ceased to return for visits will be followed up by 
mail, phone, or other means to gather information such as the reason for failure to return, the

9.5.7 
Confirmation of Medical Care by Another Physician 
The investigator will instruct subjects (or guardian/legally authorized representative) to 
inform site personnel when they are planning to receive medical care by another physician.  
At each visit, the investigator will ask the subject (or guardian/legally authorized 
representative) whether the subject has received medical care by another physician since the 
last visit or is planning to do so in the future.  When the subject is going to receive medical 
care by another physician, the investigator, with the consent of the subject (or 
guardian/legally authorized representative), will inform the other physician that the subject is 
participating in the clinical study. 
9.6 
Data Quality Assurance 
This study will be organized, performed, and reported in compliance with the protocol, 
SOPs, working practice documents, and applicable regulations and guidelines.  Site audits 
will be made periodically by the sponsor’s or the CRO’s qualified compliance auditing team, 
which is an independent function from the study team responsible for conduct of the study.   
9.6.1 
Data Collection 
Data required by the protocol will be collected on the CRFs and entered into a validated data 
management system that is compliant with all regulatory requirements.  As defined by ICH 
guidelines, the CRF is a printed, optical, or electronic document designed to record all of the 
protocol-required information to be reported to the sponsor on each study subject. 
Data collection on the CRF must follow the instructions described in the CRF Completion 
Guidelines.  The investigator has ultimate responsibility for the collection and reporting of all 
clinical data entered on the CRF.  The investigator or designee as identified on Form 
FDA 1572 must sign the completed CRF to attest to its accuracy, authenticity, and 
completeness.

9.7.1.6 
Efficacy Analyses 
Data cutoff for the primary study analysis in Phase 2 will occur when all evaluable subjects 
have completed at least 4 treatment cycles and, if applicable, a confirmatory scan has been 
performed (in case of a PR or CR at Week 16), or have discontinued study treatment early. 
The following are evaluability criteria for objective response and non-target disease response 
analysis: 
 
Evaluable for objective response:  Only those subjects who have measurable disease 
present at baseline and have their disease re-evaluated at post-baseline visits will be 
considered evaluable for objective response.  These subjects will have their response 
classified according to RECIST 1.1 (for Ewing sarcoma/pPNET and rhabdomyosarcoma) 
or RANO (for HGG). 
 
Evaluable for non-target disease response:  Subjects who have lesions present at 
baseline that are evaluable but do not meet the definitions of measurable disease and have 
had their disease re-evaluated at post-baseline visits will be considered evaluable for non-
target disease.  Subjects with only non-target disease will be summarized by their best 
overall response.  The response will be classified according to RECIST 1.1 defined 
categories for subjects with non-target disease only. 
9.7.1.6.1 PRIMARY EFFICACY ANALYSIS 
Phase 1 
The study will utilize the rolling 6 design.  The primary objective of Phase 1 is to determine 
the MTD and to establish the RP2D.   
Phase 2 
The primary efficacy endpoint in Phase 2 is ORR at 16 weeks.  Objective responses will 
count only confirmed CR and PR.  Estimated ORR and its exact 95% CI using the 
Clopper-Pearson method will be presented. 
9.7.1.6.2 SECONDARY EFFICACY ANALYSES FOR PHASE 1 AND PHASE 2 
The secondary efficacy endpoints will be ORR at the time of data cutoff, DCR, CBR and 
DOR.  These endpoints in Phase 1 will be summarized if appropriate and listed by dose level, 
and ORR will be based on only subjects with measureable disease at screening/baseline.  For 
Phase 2, the ORR, DCR and CBR will be provided with exact 95% CIs using the 
Clopper-Pearson method.  The DOR will be analyzed using Kaplan-Meier approach among 
the responders (CR or PR).  If a subject had no record of disease progression or did not die 
before the data cutoff date, or before early discontinuation (including discontinuations due to 
toxicity, undocumented clinical progression, change of cancer treatment, or decreasing 
performance status), then the subject will be censored at the last available tumor assessment.

Pharmacokinetic, Pharmacodynamic, Pharmacogenomic, and Other Biomarker 
Analyses 
9.7.1.7.1 PHARMACOKINETIC ANALYSIS 
Lenvatinib and everolimus concentration versus time data will be tabulated and summarized 
and graphically presented.   
Plasma concentrations of lenvatinib from the intense sampling in Phase 1 will be used to 
determine the following PK parameters: area under the plasma concentration time course 
profile (AUC), maximum observed concentration (Cmax), and time from dosing to the 
maximum observed concentration (Tmax).  Other PK parameters may be determined as data 
permit. 
For both lenvatinib and everolimus, data from Phase 1 and 2 of the study will be pooled with 
available data from other studies and subjected to population PK analysis.  For each drug, the 
PK model will be parameterized in terms of clearance and volume of distribution. 
Details of the population PK analysis will be provided in a separate analysis plan. 
9.7.1.7.2 PHARMACODYNAMIC, PHARMACOKINETIC/PHARMACODYNAMIC, PHARMACOGENOMIC, 
 
AND OTHER BIOMARKER ANALYSES 
Correlation between clinical response to treatment associated with a combination of 
lenvatinib and everolimus and blood or tumor biomarkers will be examined using descriptive 
statistics and graphic displays as appropriate.  Details will be provided in a separate analysis 
plan. 
Pharmacokinetic/PD exposure-safety relationships will be explored.  Safety endpoints will be 
most frequent AEs of special interest and dose reductions.  Exploratory/graphical analyses 
will be conducted for PK/PD evaluations, and may be followed by model-based analyses.  A 
detailed analysis plan will be provided separately. 
9.7.1.8 
Safety Analyses 
Safety variables include study drug exposure, treatment-emergent adverse events (TEAEs), 
laboratory tests, vital signs, 12-lead ECGs, cardiac function by echocardiography/MUGA 
scan, urine dipstick, and Lansky play scores or Karnofsky performance scores.  
All toxicities will be summarized.  The following are evaluability criteria for toxicity 
analysis: 
 
Evaluable for toxicity:  All subjects who received at least one dose of study treatment 
are evaluable for toxicity.  For Phase 1, toxicities during Cycle 1 will be used for the 
purpose of dose escalations according to the rolling 6 design.  Subjects who developed a 
DLT or received at least 75% of the prescribed dose during cycle 1 are considered fully 
evaluable for toxicity for the purpose of dose escalation.

The incidence of treatment-emergent adverse events (TEAEs) and SAEs will be summarized 
by system organ class and preferred term.  Laboratory test data, vital signs, 12-lead ECGs, 
cardiac function by echocardiography/MUGA scan, urine dipstick, Lansky play scores or 
Karnofsky performance scores, and their changes or shifts from baseline will be summarized 
using descriptive statistics, as appropriate.  Summary of study drug exposure will be 
provided.  Prior and concomitant medications, medical/surgical history and subject 
demographics will be summarized. 
9.7.1.8.1 EXTENT OF EXPOSURE 
The number of cycles/days on treatment, quantity of study drug administered, and the 
number of subjects requiring dose reductions, treatment interruption, and treatment 
discontinuation due to AEs will be summarized. 
9.7.1.8.2 ADVERSE EVENTS 
The AE verbatim descriptions (investigator terms from the CRF) will be classified into 
standardized medical terminology using the Medical Dictionary for Regulatory Activities 
(MedDRA).  Adverse events will be coded to the MedDRA lower level term (LLT) closest to 
the verbatim term.  The linked MedDRA preferred term (PT) and primary system organ class 
(SOC) are also captured in the database. 
A TEAE is defined as an AE that emerges during treatment, having been absent at 
pretreatment (baseline) or  
 
Reemerges during treatment, having been present at pretreatment (baseline) but stopped 
before treatment, or  
 
Worsens in severity during treatment relative to the pretreatment state, when the AE is 
continuous. 
Only those AEs that are treatment emergent will be included in summary tables.  All AEs, 
treatment emergent or otherwise, will be presented in subject data listings. 
The incidence of TEAEs will be reported as the number (percentage) of subjects with TEAEs 
by SOC and PT.  A subject will be counted only once within an SOC and PT, even if the 
subject experienced more than 1 TEAE within a specific SOC and PT.  The number 
(percentage) of subjects with TEAEs will also be summarized by CTCAE grade if 
appropriate. 
The number (percentage) of subjects with treatment-related TEAEs will be summarized by 
SOC and PT.  Treatment-related TEAEs include those events considered by the investigator 
to be related to study treatment.   
The number (percentage) of subjects with treatment-emergent SAEs will be summarized by 
MedDRA SOC and PT.  A subject data listing of all SAEs will be provided. 
The number (percentage) of subjects with TEAEs leading to discontinuation from study drug 
or leading to study drug dose changes will be summarized by MedDRA SOC and PT.  A

9.7.1.8.3 LABORATORY VALUES 
Laboratory results will be summarized using Système International (SI) units, as appropriate.  
For all quantitative parameters listed in Section 9.5.1.5.3, the actual value and the change 
from baseline to each post-baseline visit will be summarized by visit using descriptive 
statistics.  Qualitative parameters listed in Section 9.5.1.5.3 will be summarized using 
frequencies (number and percentage of subjects), and shifts from baseline to worst 
postbaseline will be reported using shift tables.  Percentages will be based on the number of 
subjects with both nonmissing baseline and at least 1 post-baseline results. 
Laboratory parameters will be categorized according to CTCAE grades, and shift tables from 
baseline CTCAE grades to the worst post-baseline grades will be provided.   
9.7.1.8.4 VITAL SIGNS 
Descriptive statistics for vital signs parameters (ie, systolic and diastolic BP, pulse, 
respiratory rate, temperature, weight) and changes from baseline will be presented by visit.  
A shift table of hypertension from baseline to worst post-baseline grades will be provided.  
9.7.1.8.5 ELECTROCARDIOGRAMS 
Descriptive statistics for ECG parameters and changes from baseline will be presented by 
visit.  Shift tables will present shifts from baseline in ECG interpretation (categorized as 
normal, abnormal, not clinically significant, and abnormal clinically significant) to the worst 
post-baseline assessment. 
9.7.1.8.6 OTHER SAFETY ANALYSES 
Shift tables of Lansky play scores and Karnofsky performance scores from baseline will be 
provided.  
Descriptive statistics and changes from baseline for left ventricular shortening fraction 
assessed on echocardiogram and LVEF assessed on echocardiogram or MUGA scans will be 
presented.  Percent reduction from baseline will also be summarized. 
9.7.2 
Determination of Sample Size 
Phase 1 – Determination of the Maximum Tolerated Dose:  The total number of subjects 
required for the Phase 1 portion of this study will depend upon the toxicities observed as the 
study progresses.  The minimum number of evaluable subjects required for this study is 4.  
The projected maximum number of evaluable subjects required is 48.  Once the MTD or 
RP2D has been defined, up to 6 additional subjects with recurrent or refractory solid tumors 
may be enrolled to acquire PK data in a representative number of young subjects.  Therefore, 
a maximum of 54 subjects are expected to be enrolled in the 4 dose escalation levels, and PK 
expansion.  The Phase 1 part of the study is expected to be completed within 18 months.  In

the event that each of Dose Levels -1, 1, 2, and 3 are expanded to 12 subjects, an absolute 
maximum of 54 subjects would be required allowing for 20% to be non-evaluable and 
including up to 6 additional subjects for PK analysis. 
Phase 2:  Phase 2 will require a minimum of 10 evaluable subjects per disease cohort and a 
maximum of 20 (10 evaluable subjects in each stage of Simon’s optimal 2-stage design).  
Therefore, a maximum of 22 subjects per cohort will be enrolled to allow for a 10% 
non-evaluable rate.  This design has 88% power to detect a 20% increase in the response rate 
at the significance level of one-sided alpha = 0.07 assuming a null response rate of 5% and 
alternative response rate ≥25%.  
9.7.3 
Interim Analysis 
For each disease cohort (Ewing sarcoma/pPNET, rhabdomyosarcoma and HGG) in Phase 2, 
there will be 1 futility analysis: this is planned for after the first 10 evaluable subjects have 
completed at least 4 treatment cycles and, if applicable, a confirmatory scan has been 
performed (in case of a PR or CR at week 16), or have discontinued study drug early (before 
Week 16).  At the futility analysis, if there are no responders (CR/PR), then the enrollment 
for that cohort will be discontinued for lack of efficacy.  If 1 or more responses are observed, 
the accrual will continue. 
Independent data monitoring committee (IDMC) 
Safety monitoring will be conducted by an independent data monitoring committee (IDMC).  
The frequency of safety reviews will be defined in the IDMC charter.  Minutes from the open 
meetings of the IDMC will be provided if requested by regulatory agencies.  The function 
and membership of the IDMC will be described in the IDMC charter.

Other Statistical/Analytical Issues 
Not applicable.

Procedure for Revising the Statistical Analysis Plan 
If the SAP needs to be revised after the study starts, the sponsor will determine how the 
revision impacts the study and how the revision should be implemented.  The details of the 
revision will be documented and described in the clinical study report.

11 PROCEDURES AND INSTRUCTIONS (ADMINISTRATIVE 
PROCEDURES) 
11.1 Changes to the Protocol 
Any change to the protocol requires a written protocol amendment or administrative change 
that must be approved by the sponsor before implementation.  Amendments specifically 
affecting the safety of subjects, the scope of the investigation, or the scientific quality of the 
study require submission to health or regulatory authorities as well as additional approval by 
the applicable IRBs/IECs.  These requirements should in no way prevent any immediate 
action from being taken by the investigator, or by the sponsor, in the interest of preserving 
the safety of all subjects included in the study.  If the investigator determines that an 
immediate change to or deviation from the protocol is necessary for safety reasons to 
eliminate an immediate hazard to the subjects, the sponsor’s medical monitor (or appropriate 
study team member) and the IRB/IEC for the site must be notified immediately.  The sponsor 
must notify the health or regulatory authority as required per local regulations. 
Protocol amendments that affect only administrative aspects of the study may not require 
submission to health or regulatory authority or the IRB/IEC, but the health or regulatory 
authority and IRB/IEC (or if regionally required, the head of the medical institution) should 
be kept informed of such changes as required by local regulations.  In these cases, the 
sponsor may be required to send a letter to the IRB/IEC and the Competent Authorities (or, if 
regionally required, the head of the medical institution) detailing such changes. 
11.2 Adherence to the Protocol 
The investigator will conduct the study in strict accordance with the protocol (refer to 
ICH E6, Section 4.5). 
11.3 Monitoring Procedures 
The sponsor’s/CRO’s CRA will maintain contact with the investigator and designated staff 
by telephone, letter, or email between study visits.  Monitoring visits to each site will be 
conducted by the assigned CRA as described in the monitoring plan.  The investigator (or if 
regionally required, the head of the medical institution) will allow the CRA to inspect the 
clinical, laboratory, and pharmacy facilities to assure compliance with GCP and local 
regulatory requirements.  The CRFs and subject’s corresponding original medical records 
(source documents) are to be fully available for review by the sponsor’s representatives at 
regular intervals.  These reviews verify adherence to study protocol and data accuracy in 
accordance with local regulations.  All records at the site are subject to inspection by the 
local auditing agency and to IRB/IEC review. 
In accordance with ICH E6, Section 1.52, source documents include, but are not limited to, 
the following: 
 
Clinic, office, or hospital charts

 
Copies or transcribed health care provider notes that have been certified for accuracy 
after production 
 
Recorded data from automated instruments such as IxRS, x-rays, and other imaging 
reports (eg, sonograms, CT scans, magnetic resonance images, radioactive images, ECGs, 
rhythm strips, electroencephalograms, polysomnographs, pulmonary function tests) 
regardless of how these images are stored, including microfiche and photographic 
negatives 
 
Pain, quality of life, or medical history questionnaires completed by subjects 
 
Records of telephone contacts 
 
Diaries or evaluation checklists 
 
Drug distribution and accountability logs maintained in pharmacies or by research 
personnel 
 
Laboratory results and other laboratory test outputs (eg, urine pregnancy test result 
documentation and urine dip-sticks) 
 
Correspondence regarding a study subject’s treatment between physicians or memoranda 
sent to the IRBs/IECs 
 
CRF components (eg, questionnaires) that are completed directly by subjects and serve as 
their own source 
11.4 Recording of Data 
A CRF is required and must be completed for each subject by qualified and authorized 
personnel.  All data on the CRF must reflect the corresponding source document, except 
when a section of the CRF itself is used as the source document.  Any correction to entries 
made on the CRF must be documented in a valid audit trail where the correction is dated, the 
individual making the correct is identified, the reason for the change is stated, and the 
original data are not obscured.  Only data required by the protocol for the purposes of the 
study should be collected. 
The investigator must sign each CRF.  The investigator will report the CRFs to the sponsor 
and retain a copy of the CRFs. 
11.5 Identification of Source Data 
All data to be recorded on the CRF must reflect the corresponding source documents.  For 
the following items, the data recorded directly on the CRF are to be considered source data: 
 
Study drug compliance (eg, the reason for any change of dosage) 
 
Indication for prior/concomitant medication (drug/therapy) 
 
Discontinuation information (eg, in the case of lost to follow-up due to the subject 
choice) 
 
Sampling date and time for the drug concentration 
 
Sampling date for the clinical laboratory tests

 
Comments and other information on AEs (eg, severity, relationship to study drug, 
outcome) 
11.6 Retention of Records 
The circumstances of completion or termination of the study notwithstanding, the 
investigator (or if regionally required, the head of the medical institution or the designated 
representative) is responsible for retaining all study documents, including but not limited to 
the protocol, copies of CRFs, the Investigator's Brochure, and regulatory agency registration 
documents (eg, Form FDA 1572, ICFs, and IRB/IEC correspondence).  The site should plan 
to retain study documents, as directed by the sponsor, for at least 15 years following the 
completion of the study. 
For sites in Canada, the Sponsor should retain all study documents to maintain complete and 
accurate records, including those specified above, for a period of 25 years. 
It is requested that at the completion of the required retention period, or should the 
investigator retire or relocate, the investigator contact the sponsor, allowing the sponsor the 
option of permanently retaining the study records. 
11.7 Auditing Procedures and Inspection 
In addition to routine monitoring procedures, the sponsor’s Clinical Quality Assurance 
department conducts audits of clinical research activities in accordance with the sponsor’s 
SOPs to evaluate compliance with the principles of ICH GCP and all applicable local 
regulations.  If a government regulatory authority requests an inspection during the study or 
after its completion, the investigator must inform the sponsor immediately. 
11.8 Handling of Study Drug 
All study drug will be supplied to the principal investigator (or a designated pharmacist) by 
the sponsor.  Drug supplies must be kept in an appropriate secure area (eg, locked cabinet) 
and stored according to the conditions specified on the drug labels.  The investigator (or a 
designated pharmacist) must maintain an accurate record of the shipment and dispensing of 
the study drug in a drug accountability ledger, a copy of which must be given to the sponsor 
at the end of the study.  An accurate record of the date and amount of study drug dispensed to 
each subject must be available for inspection at any time.  The CRA will visit the site and 
review these documents along with all other study conduct documents at appropriate 
intervals once study drug has been received by the site. 
All drug supplies are to be used only for this study and not for any other purpose.  The 
investigator (or site personnel) must not destroy any drug labels or any partly used or unused 
drug supply before approval to do so by the sponsor.  At the conclusion of the study and as 
appropriate during the study, the investigator (or a designated pharmacist) will return all used 
and unused drug containers, drug labels, and a copy of the completed drug disposition form 
to the sponsor’s CRA (or designated contractor) or, when approval is given by the sponsor, 
will destroy supplies and containers at the site.

11.9 Publication of Results 
All manuscripts, abstracts, or other modes of presentation arising from the results of the 
study must be reviewed and approved in writing by the sponsor in advance of submission 
pursuant to the terms and conditions set forth in the executed Clinical Trial Agreement 
between the sponsor/CRO and the institution/investigator.  The review is aimed at protecting 
the sponsor's proprietary information existing either at the date of the commencement of the 
study or generated during the study. 
The detailed obligations regarding the publication of any data, material results, or other 
information generated or created in relation to the study shall be set out in the agreement 
between each investigator and the sponsor or CRO, as appropriate. 
11.10 Disclosure and Confidentiality 
The contents of this protocol and any amendments and results obtained during the study 
should be kept confidential by the investigator, the investigator’s staff, and the IRB/IEC and 
will not be disclosed in whole or in part to others, or used for any purpose other than 
reviewing or performing the study, without the written consent of the sponsor.  No data 
collected as part of this study will be used in any written work, including publications, 
without the written consent of the sponsor.  These obligations of confidentiality and non-use 
shall in no way diminish such obligations as set forth in either the Confidentiality Agreement 
or Clinical Trial Agreement executed between the sponsor/CRO and the 
institution/investigator. 
All persons assisting in the performance of this study must be bound by the obligations of 
confidentiality and non-use set forth in either the Confidentiality Agreement or Clinical Trial 
Agreement executed between the institution/investigator and the sponsor/CRO. 
11.11 Discontinuation of Study 
The sponsor reserves the right to discontinue the study for medical reasons or any other 
reason at any time.  If a study is prematurely terminated or suspended, the sponsor will 
promptly inform the investigators/institutions and regulatory authorities of the termination or 
suspension and the reason(s) for the termination or suspension.  The IRB/IEC will also be 
informed promptly and provided the reason(s) for the termination or suspension by the 
sponsor or by the investigator/institution, as specified by the applicable regulatory 
requirement(s). 
The investigator reserves the right to discontinue the study should his/her judgment so 
dictate.  If the investigator terminates or suspends a study without prior agreement of the 
sponsor, the investigator should inform the institution where applicable, and the 
investigator/institution should promptly inform the sponsor and the IRB/IEC and provide the 
sponsor and the IRB/IEC with a detailed written explanation of the termination or

12 APPENDICES 
Appendix 1 
Response Evaluation Criteria in Solid Tumors 
(RECIST) 1.1 
Tumor response assessments in this clinical trial will use Response Evaluation Criteria in 
Solid Tumors (RECIST 1.1) based on the 2009 article by Eisenhauer et al entitled New 
response evaluation criteria in solid tumors: revised RECIST guideline (version 1.1) 
(Eisenhauer, et al., 2009). 
The sole modification to RECIST 1.1 to be implemented in this trial is that chest x-rays may 
not be used to follow disease; only CT scans may be used to follow chest disease.  As 
required by RECIST 1.1, the protocol states that the minimum duration of stable disease is 
7 weeks following the date of first dose of study drug.

Appendix 2 
Common Terminology Criteria for Adverse Events 
(v4.0) 
The National Cancer Institute’s Common Terminology Criteria for Adverse Events provides 
descriptive terminology to be used for adverse event reporting in clinical trials.  An updated 
version (4.03) is now in use as of 14 Jun 2010.  Version 4.03 includes clarifications for a 
select few grading scales and adverse event term definitions.  A brief definition is provided to 
clarify the meaning of each AE term.  To increase the accuracy of AE reporting, all adverse 
event terms in CTCAE version 4.03 have been correlated with single-concept, Medical 
Dictionary for Regulatory Activities (MedDRA®) terms. 
CTCAE v4.03 grading refers to the severity of the AE.  CTCAE grades 1 through 5, with 
unique clinical descriptions of severity for each AE, are based on this general guideline: 
Grade 
CTCAE Status 
1 
Mild: asymptomatic or mild symptoms; clinical or diagnostic observations 
only; intervention not indicated. 
2 
Moderate: minimal, local, or noninvasive intervention indicated; limiting age-
appropriate instrumental activities of daily living (ADL).a 
3 
Severe or medically significant but not immediately life-threatening: 
hospitalization or prolongation of hospitalization indicated; disabling, limiting 
self-care ADL.b 
4 
Life-threatening consequences: urgent intervention indicated. 
5 
Death related to adverse event. 
CTCAE = Common Terminology Criteria for Adverse Events. 
a:  Instrumental ADL refers to preparing meals, shopping for groceries or clothes, using the telephone, managing money, 
etc. 
b:  Self-care ADL refers to bathing, dressing and undressing, feeding self, using the toilet, taking medications, and not 
bedridden.

Appendix 11 
Pharmacodynamic, Pharmacogenomic, and Other 
Biomarker Research 
Subjects enrolled in this clinical study will have biologic samples collected for 
pharmacodynamic (PD), pharmacogenomic (PG), and other biomarker analysis.  These 
samples may be used for discovery or validation to identify biomarkers that may be used for 
exploratory evaluation of response and/or safety-related outcomes as well as for use in 
diagnostic development. 
The PG samples may be used to identify genetic factors that may influence a subject’s 
exposure to the study drug, as well as genetic factors that may have an effect on clinical 
response or potential adverse events related to study treatment, and to explore the role of 
genetic variability in response.  Samples may be analyzed to determine a subject’s genotypes 
or sequence for a number of genes or non-coding regulatory regions.  The research may 
include the investigation of polymorphisms in genes that are likely to influence the study 
drug pharmacokinetics or therapeutic response. 
Collection of the PD, PG, and other biomarker samples (optional) will be bound by the 
sample principles and processes outlined in the main/separate study protocol.   
Sample Collection and Handling 
The samples will be collected according to the study flow chart.  If, for operational or 
medical reasons, the genomic DNA blood sample cannot be obtained at the prespecified visit, 
the sample can be taken at any study center visit at the discretion of the investigator and site 
staff. 
Security of the Samples, Use of the Samples, Retention of the Samples 
Sample processing, for example DNA and/or RNA extraction, genotyping, sequencing, or 
other analysis will be performed by a laboratory under the direction of the sponsor.  
Processing, analysis, and storage will be performed at a secure laboratory facility to protect 
the validity of the data and maintain subject privacy. 
Samples will only be used for the purposes described in this protocol.  Laboratories 
contracted to perform the analysis on behalf of the sponsor will not retain rights to the 
samples beyond those necessary to perform the specified analysis and will not transfer or sell 
those samples.  The sponsor will not sell the samples to a third party. 
Samples will be stored for up to 15 years after the completion of the study (defined as 
submission of the clinical study report to the appropriate regulatory agencies).  At the end of 
the storage period, samples will be destroyed.  Samples may be stored longer if a health 
authority (or medicinal product approval agency) has active questions about the study.  In 
this special circumstance, the samples will be stored until the questions have been adequately 
addressed.

It is possible that future research and technological advances may identify genomic variants 
of interest, or allow alternative types of genomic analysis not foreseen at this time.  Because 
it is not possible to prospectively define every avenue of future testing, all samples collected 
will be single or double coded (according to the ICH E15 guidelines) in order to maintain 
subject privacy.  
Right to Withdraw 
If, during the time the samples are stored, a participant would like to withdraw his/her 
consent for participation in this research, Eisai will destroy the samples.  Information from 
any assays that have already been completed at the time of withdrawal of consent will 
continue to be used as necessary to protect the integrity of the research project. 
Subject Privacy and Return of Data 
No subject-identifying information (eg, initials, date of birth, government identifying 
number) will be associated with the sample.  All PD and other biomarker samples will be 
single coded.  Genomic DNA samples used to explore the effects on PK, treatment response, 
and safety will be single coded.  Genomic DNA samples that will be stored for long-term use 
(defined as 15 years after the completion of the study) will be double coded.  Double coding 
involves removing the initial code (subject ID) and replacing with another code such that the 
subject can be re-identified by use of 2 code keys.  The code keys are usually held by 
different parties.  The key linking the sample ID to the subject number will be maintained 
separately from the sample.  At this point, the samples will be double-coded, the first code 
being the subject number.  Laboratory personnel performing genetic analysis will not have 
access to the “key.”  Clinical data collected as part of the clinical trial will be cleaned of 
subject identifying information and linked by use of the sample ID “key.” 
The sponsor will take steps to ensure that data are protected accordingly and confidentiality 
is maintained as far as possible.  Data from subjects enrolled in this study may be analyzed 
worldwide, regardless of location of collection. 
The sponsor and its representatives and agents may share coded data with persons and 
organizations involved in the conduct or oversight of this research.  These include: 
 
Clinical research organizations retained by the sponsor  
 
Independent ethics committees or institutional review boards that have responsibility for 
this research study  
 
National regulatory authorities or equivalent government agencies 
At the end of the analysis, results may be presented in a final report which can include part or 
all of the coded data, in listing or summary format.  Other publication (eg, in peer-reviewed 
scientific journals) or public presentation of the study results will only include summaries of 
the population in the study, and no identified individual results will be disclosed.

Given the research nature of the PD, PG, and other biomarker analysis, it will not be possible 
to return individual data to subjects.  The results that may be generated are not currently 
anticipated to have clinical relevance to the patients or their family members.  Therefore, 
these results will not be disclosed to the patients or their physicians. 
If at any time, PD, PG, and/or other biomarker results are obtained that may have clinical 
relevance, IRB review and approval will be sought to determine the most appropriate manner 
of disclosure and to determine whether or not validation in a Clinical Laboratory 
Improvement Amendments (CLIA)-certified setting will be required.  Sharing of research 
data with individual patients should only occur when data have been validated by multiple 
studies and testing has been done in CLIA-approved laboratories.

Preparation of Lenvatinib suspension 
Wash hands thoroughly with soap and water before putting on and after removing gloves.  
Double gloves should be worn at all times during preparation and administration of 
lenvatinib. 
Young and other children in the home should not be near the area where lenvatinib 
suspension is being prepared or administered. 
Ensure proper disposal of all the materials for administration by disposing directly into the 
designated waste container to protect children or anyone who may handle the trash. 
Caregivers should not open the capsule in order to avoid repeated exposure to the 
contents of the capsule. 
If a dose is missed and cannot be taken within 12 hours, skip that dose and take the next dose 
at the usual time of administration. 
All unused products and packaging from used products should be returned to the site by the 
patient or caregiver at the next visit.  Do not throw away any medicines via wastewater or 
household waste. 
Preparation of suspension: Prepare the suspension as illustrated below by either the oral 
method (a) or by a nasogastric tube (b).  Prepare the suspension with water or apple juice.  
The suspension should be directly administered into the mouth of the subject and washed 
down with additional fluid added to the syringe after the medication is administered; likewise 
for nasogastric administration.  The suspension should be administered immediately after 
preparation.

Appendix 13 
Imaging Scans Methodology for Tumor Assessment 
For All Tumor Types Except High Grade Glioma (HGG) 
Screening computed tomography (CT) scans should be performed with oral and iodinated 
intravenous contrast and magnetic resonance imaging (MRI) scans should be performed with 
IV gadolinium chelate.  Post-screening scans may be performed without contrast if a medical 
contraindication develops while on study treatment.  If iodinated IV contrast is 
contraindicated, chest CT should be done without IV contrast.  MRI should be performed for 
all other body regions (with gadolinium unless contraindicated (eg, severe renal dysfunction). 
CT scans should be of diagnostic quality spiral/multidetector CT with oral and iodinated IV 
contrast, and the MRI scans should be performed with IV gadolinium chelate.  Scans of the 
abdomen, pelvis, and other areas of the body may be done with MRI instead of CT, but 
evaluation of the chest should be done with CT.  Spiral/multidetector CT should be 
performed with a t-mm contiguous slice reconstruction algorithm.  If body MRI scans are 
performed, contiguous slices of 5 mm should also be performed.  If a subject develops a 
contraindication to CT contrast during the study, the chest evaluation should be done with 
non-contrast CT, and the other body scans should be done with MRI with gadolinium chelate 
IV. 
The same imaging modality and image-acquisition protocol (including use or non-use of 
contrast) should be used consistently across all time points to allow consistent comparison of 
lesions.  Low-dose non-contrast CT transmission scans from a positron emission 
tomography-CT (PET-CT) combination scanner are not acceptable.  Ultrasound should not 
be used for radiographic tumor assessment.  A chest x-ray or skeletal x-ray which clearly 
demonstrates a new metastatic lesion may be used to document progression in lieu of the 
CT/MRI scans. 
If subcutaneous masses or nodes are palpable (eg, bulky) and are assess by both clinical and 
radiographic techniques, the radiographic (CT/MRI) technique should be used for the 
assessment of target and non-target lesions. 
18-Fluoro-2-deoxyglucose whole-body positron emission tomography (18FDG-PET) scans 
may be used to assess new lesions if used according to RECIST 1.1 (a new FDG-avid lesion 
if there is a negative 18FDG-PET scan at baseline; if there was no baseline 18FDG-PET scan, 
a potential new lesion must be demonstrated with CT or MRI). 
For HGG 
A standard MRI imaging protocol will be performed for use in the assessment.  The brain 
MRI sequences will include axial T1-weighted spin-echo imaging obtained using a TR of 
400 – 600 ms, a TE of 15 ms or less, a field of view of 22 – 24 cm, a matrix of 256 x 256, a 
slice thickness of 5 mm and intraslice gaps of 1.5 mm or less; axial T2-weighted fast spin 
echo images using a TR of 2500 – 4500 ms, TE of 100 – 130 ms, echo train length (ETL) of 
13 – 25, FOV or 22 – 24 cm, a matrix of 256 x 256, a slice thickness of 5 mm and intraslice 
gaps of 1.5 mm or less; axial FLAIR images using a TR of 6000 – 9000 ms, TE of 100 – 130

ms, TI of 2000 – 2500 ms,  ETL of 13 – 25, a matrix of 256 x 192-256, a slice thickness of 5 
mm and intraslice gaps of 1.5 mm or less.  After the intravenous injection of 0.1 mmol/kg of 
gadolinium containing contrast agent, a T1-weighted axial acquisition will be performed 
using the same parameter ranges as above, followed by a whole brain sagittal or coronal 3D 
volumetric T1-weighted spoiled gradient echo or fast low angle shot sequence using TR less 
than 10 ms, TE less than 5 ms, FOV of 25.6 cm or less, and a matrix size appropriate for 
obtained voxels that are 1.3 mm or less in any direction.

Appendix 14 
Response Assessment in Neuro-Oncology (RANO) 
Criteria 
The RANO guidelines are as follows: 
Specific lesions are to be evaluated serially with comparative analysis of changes in the area 
of contrast enhancement, as well as the non-enhancing component will be performed.  The 
product of the maximal cross sectional enhancing diameters will be used to determine the 
size of the contrast-enhancing lesions as follows: 
 
Measurable disease is defined as bidimensionally contrast-enhancing lesions with 
clearly defined margins by CT or MRI scan, with a minimal diameter of 1 cm, and visible 
on 2 axial slices which are preferably at most 5 mm apart with 0 mm skip.  
 
Non-measurable disease is defined as either unidimensionally measurable lesions, 
masses with margins not clearly defined, or lesions with maximal perpendicular 
diameters <1cm. If there are multiple contrast-enhancing lesions, a maximum of 5 of the 
largest lesions may be measured and the sum of the products of the perpendicular 
diameters of these lesions determined. 
 
For subjects with recurrent disease who have multiple lesions of which only 1 or 2 are 
increasing in size, the enlarging lesions should be considered the target lesions for 
evaluation of response. 
 
Given the difficulty of differentiating “pseudoprogression” from true progression in the 
first 3 months after irradiation, subjects in this window should only be classified as 
progressive disease if the progression is outside the radiation field (beyond the high dose 
region or 80% isodose line) or if there is pathologic confirmation of disease progression. 
 
Radiographic response should be determined in comparison to the tumor measurement 
obtained at pretreatment baseline for determination of response, and the smaller of 
baseline or the smallest tumor measurement following initiation of therapy (nadir) for 
determination of progression: 
- 
Complete Response (CR):  Complete disappearance of all enhancing measurable and 
non-measurable disease sustained for at least 4 weeks.  In the absence of a confirming 
scan at least 4 weeks later, this scan will be considered only stable disease.  No new 
lesions.  Stable or improved non-enhancing (T2/FLAIR) lesions.  Subjects must be on 
no corticosteroids and stable or improved clinically. 
- 
Partial Response (PR):  Greater than or equal to 50% decrease, compared to baseline, 
in the sum of products of perpendicular diameters of all measurable enhancing lesions 
sustained for at least 4 weeks.  In the absence of a confirming scan 4 weeks later, this 
scan will be considered only stable disease.  No progression of non-measurable 
disease.  No new lesions.  Stable or improved nonenhancing (T2/FLAIR) lesions on 
same or lower dose of corticosteroids compared to baseline scan.  Subjects should be 
on a corticosteroid dose that should not be greater than the dose at time of baseline 
scan, and should be stable or improved clinically. 
- 
Stable Disease (SD):  This occurs if the subjects did not qualify for CR, PR, or 
progressive disease (PD) (see below).  There should be stable or improved

nonenhancing (T2/FLAIR) lesions on same or lower dose of corticosteroids compared 
to baseline scan.  In the event that the corticosteroid dose has been increased, the last 
scan considered to show stable disease will be the scan obtained when the 
corticosteroid dose was equivalent to the baseline dose.  The subject should be stable 
or improved clinically. 
- 
Progressive Disease (PD):  Progression is defined as >25% increase in sum of the 
products of perpendicular diameters of enhancing lesions (over baseline if no 
decrease) on stable or increasing doses of corticosteroids and/or a significant increase 
in T2/FLAIR non-enhancing lesion on stable or increasing doses of corticosteroids 
compared to baseline scan or best response following initiation of therapy, not due to 
co-morbid events.  Any new lesion.  Clear clinical deterioration not attributable to 
other causes apart from the tumor.  Failure to return for evaluation due to death or 
deteriorating condition is considered progressive disease as well.
