Brief summary:
Determine wether 24 months treatment with everolimus prolongs progression free survival rate (based on a central assessment) after embolisation ou chemoembolisation for liver metastases.

* H0 a 24 months progression free survival rate less than 35% is unacceptable
* H1 a 24 months progression free survival rate greater than 35% would show that everolimus treatment is beneficial, the expected 24 months progression free survival rate being 50%

Detailed description:

Arms: arm 1: After 2 sessions of embolization with microsphere of 100 to 500 µm or chemoembolization with 100 mg of doxorubicine and 10 ml of lipiodol, administered every day, 10 mg of everolimus during 24 months or until progression (hepatic and other site).
Interventions: intervention 1: Everolimus intervention 2: embolization intervention 3: Doxorubicin
Intervention descriptions: intervention 1: 10 mg per day of everolimus during 24 months or until progression disease intervention 2: 2 sessions embolization with spheric particles intervention 3: 2 sessions chemoembolization with 10 mg of lipiodol with 100 mg of doxorubicine

Objectives 
Principal:  
The primary objective of the study is to determine whether treatment with 
everolimus for 24 months prolongs progression-free survival according to

24 months in patients receiving hepatic embolization or chemoembolization 
followed by everolimus therapy. 
Secondary:  
- 
Progression-free survival at 24 months (hepatic and non-hepatic) 
- 
Overall survival at 24 months 
- 
Tolerance of the treatment during the 24 months of treatment   
Inclusion criteria  
-

chemoembolization for antitumor purposes due to the progressive nature 
of liver metastases (morphological progression over the last 12 months 
according to RECIST V1.1 criteria) 
- 
Age ≥ 18 years 
- 
General condition WHO ≤ 2  
-

o 24-hour proteinuria (for patients who will receive streptozotocin 
for chemoembolization) < 1.5 N  
o Fasting serum cholesterol ≤ 300 mg/dL or 7.75 mmol/L and 
triglycerides ≤ 2.5 x LNS (in the event that one or both of these 
thresholds are exceeded, the patient can be included in the study 
only after initiation of appropriate lipid-lowering therapy) 
- 
Complete resolution or persistence with a maximum grade of 1 (except 
for transaminases or INR if anticoagulant) of toxicities from any 
previous treatments (NCI CTC version 4.0)

Study design and 
treatment plan  
 
Hepatic arterial embolization or chemoembolization followed by 24 months of 
everolimus treatment. 
Possibility of performing hepatic arterial embolization alone or in combination 
with doxorubicin or streptozotocin chemotherapy. The modalities and the 
treatment plan (number of sessions planned to obtain a complete hepatic 
treatment, maximum 2 sessions authorized) must be defined before the patient's 
inclusion in the trial and specified in the report of the PCR. 
Everolimus (10 mg/d) will be started 7 days after embolization or 
chemoembolization or after improvement of liver toxicity to a grade ≤1. 
Treatment should not be initiated beyond 30 days after embolization or 
chemoembolization. 
Duration of everolimus treatment: 24 months after the first embolization or 
chemoembolization in the absence of unacceptable toxicity. 
In the situation where several embolization or chemoembolization sessions are 
planned, everolimus will be stopped for the time of the embolization or 
chemoembolization 
(stopped 
the 
day 
before 
the 
embolization 
or 
chemoembolization and restarted as described above) 
Morphological evaluation every 3 months by triphasic thoraco-abdomino-pelvic 
CT scan 
Statistical 
methods 
 
According to the literature, the median progression-free survival after 
embolization or chemoembolization ranges from 15 to 19 months with a 
progression-free survival rate of approximately 35%. As there is no information 


FFCD 1104-EVACEL 
 
 
 
 
9/36 
V1.2 -18.08.2015 amendment 5 
on progression-free survival in the literature, the hypotheses were built on the 
progression-free survival data. 
 The assumptions used to calculate the number of subjects are as follows: 
H0: a 24-month progression-free survival rate of less than 35% is not acceptable  
H1: A 24-month progression-free survival rate of more than 35% would 
demonstrate the utility of adjuvant everolimus therapy with an expected 24-
month progression-free survival rate of 50%. 
To obtain a power of 80% with a first-species risk of 5% (one-sided), it is 
required to include 68 patients according to the assumptions established above 
(using the exact binomial distribution). 
Taking into account a rate of lost to follow-up or patients not evaluable for any 
reason except death, 72 patients will be included. 
The data will be described according to the usual methods detailed in the 
statistical analysis plan. The analysis will be performed on an intention-to-treat 
basis.

Possibility of performing hepatic arterial embolization alone or associated with chemotherapy 
with doxorubicin or streptozotocin. 
The two embolization or chemoembolization sessions should be spaced 4 to 8 weeks apart.  
The modalities and the treatment plan (number of sessions planned to obtain a complete hepatic 
treatment, maximum 2 sessions authorized) must have been defined before the inclusion of the 
patient in the trial and specified on the report of the PCR. 
When 2 embolization or chemoembolization sessions are planned, a CT scan may be performed 
before the 2ème session if necessary for technical reasons. This CT scan should not be used to 
evaluate the tumor response. 
 
DESCRIPTION OF THE TECHNIQUE 
 
Pre-therapeutic angiography should always be performed to confirm portal system patency and 
tumor hypervascularity and to rule out a significant arteriovenous shunt.  
Identification and protection of the cystic and gastric arteries is recommended. 
 
We will always try to favor chemoembolization versus simple embolization. If the choice is 
simple embolization, it should be performed with particles of 500 microns maximum and until 
complete stagnation in the targeted arteries. 
 
Desirable doses for chemoembolization injections 
- 
100 mg doxorubicin (reconstituted in 5 mL or the smallest possible volume of fluid). 
Doxorubicin may be reconstituted in X-ray contrast medium to increase density and promote 
emulsion stability or 1500 mg of streptozotocin  
- 
10 ml of lipiodol ideally  
- 
Spherical embolization particles: from 100 to 700 microns depending on the 
operator's preference and should always be performed until complete stasis. 
 
PREPARATION AND INJECTION TECHNIQUE 
 
Chemoembolization 
The use of loaded microspheres is not allowed chemoembolization must involve the use of 
an emulsion of doxorubicin or streptozotocin and Lipiodol 
- 
Preparation of the emulsion with two 20CC uher lock syringes connected by a three-
way valve. The mixing process should be initiated by pushing the doxorubicin or 
streptozotocin towards the Lipiodol (the aim is to promote a water-in-oil emulsion) and 
by making about 20 back and forth syringes. The mixture obtained must be injected 
before embolization under scopic control and with a flow rate avoiding arterial reflux.   
- 
The use of a microcatheter is recommended in case of localized disease in order to obtain 
an ultra-selective positioning. 
- 
It is imperative to try to perform the embolization in addition to the chemopiodol and 
therefore to stop the injection of the drug/Lipiodol emulsion before complete stagnation, 
or failing that to wait at least 10 minutes after injection of the chemopiodol to obtain a 
flow capable of allowing the embolization.  
- 
Subsequent particle embolization should result in complete stasis in the targeted arteries 
at least to the second-order arteries in case of lobar involvement. 
 
Embolization 
The use of spherical embolization particles of 100 to 500 microns according to the 


FFCD 1104-EVACEL 
 
 
 
 
15/36 
V1.2 -18.08.2015 amendment 5 
operators' choice. The injection is done in a slow way with spheres suspended in the 
saline/contracts mixture in order to avoid aggregation of particles responsible for 
proximal occlusions. Embolization is complete to the second and third order branches. 
Stasis should be observed for 10 minutes before deciding to terminate the procedure. 
There is no limitation in the volume of embolization that can be used. 
- 
For patients with bilobar involvement, each lobe must be treated separately. A 
catheter is placed in a lobar hepatic artery for total embolization. The second 
session should be performed on the other lobe. 
- 
The use of a microcatheter is recommended in case of localized disease in order to 
obtain an ultra-selective positioning      
 
Patients with localized lesion(s) should be treated with an even distribution of the dose of 
doxorubicin or streptozotocin within the lesion(s). If possible, chemoembolization should be 
repeated in the same manner. The two sessions should be separated by 4 to 8 weeks. 
For patients with bilobar involvement, each lobe should be treated separately. A catheter is 
placed in a lobar hepatic artery and the full dose of doxorubicin/lipiodol or 
streptozotocin/lipiodol is administered. The second session should be performed in the other 
lobe.  
 
Embolization or chemoembolization must always be associated with appropriate analgesic 
treatment, prophylactic antibiotic therapy and/or premedication with corticosteroids, the 
modalities of which are left to the discretion of the investigator. 
 
Repeat chemoembolization sessions:  
Three sessions are planned with intervals of 6 to 8 weeks. 
The second and third session will be performed depending on the initial tumor response. An 
additional session is not recommended in case of complete lipiodolated fixation of all tumor 
targets. 
In case of bleeding and/or severe liver failure secondary to an embolization or 
chemoembolization session, the following session(s) will be cancelled.  For any other toxicity 
secondary to a TACE session, the performance of one (or two) additional sessions will be left 
to the discretion of the investigator. 
 
Lipiodol and doxorubicin or streptozotocin are reported to health authorities as non-
investigational drugs. 
However, the tolerance of 2 embolization or chemembolization sessions will be collected in the 
observation booklet. 
 
2- Everolimus treatment 
 
Everolimus, an investigational treatment, is being provided as part of the study. It will be 
supplied in boxes of 30 tablets. The tablets will be either 10 mg or 5 mg. The boxes will be 
labeled "clinical trial" as recommended. 
 
The dosage is 10 mg/day, i.e. 1 tablet of 10 mg or 2 tablets of 5 mg. In case of toxicity, refer 
to paragraph VII for dose adjustments. 
 
Everolimus treatment will be continued for a maximum of 24 months after the first embolization 
or chemoembolization. 
 


FFCD 1104-EVACEL 
 
 
 
 
16/36 
V1.2 -18.08.2015 amendment 5 
Everolimus will be started 7 days after embolization or chemoembolization or when liver 
toxicities have returned to a grade ≤1 according to the NCI CTIC version 4.0 toxicity scale. 
Treatment should not be initiated beyond 30 days after embolization or chemoembolization. 
 
If embolization or chemoembolization cannot be performed after patient inclusion, everolimus 
MUST NOT be started.   
If embolization or chemoembolization is postponed, wait for embolization or 
chemoembolization to start everolimus as described above. If embolization or 
chemoembolization is definitely cancelled, DO NOT ADMINISTER everolimus and follow the 
patient according to the recommendations (see paragraph VIII-2: monitoring after cessation of 
treatment).  
 
For the second session, everolimus will be stopped the day before the session and restarted in 
the same manner as initially, i.e., 7 days after embolization or chemoembolization or when liver 
toxicities have returned to a grade ≤1 according to the NCI CTIC toxicity scale version 4.0 and 
within a maximum of 30 days after embolization or chemoembolization. 
 
Method of administration 
Everolimus should be taken orally once a day at the same time each day, with or without food. 
The tablets should be swallowed whole with a glass of water. The tablets should not be chewed 
or crushed. 
If a dose is missed, the patient should not take an additional dose, but should take the next 
prescribed dose.  
 
 
3- Concomitant treatments to be avoided  
 
Everolimus is a substrate of CYP3A4 and a moderate inhibitor of P-glycoprotein (PgP). 
Therefore, the absorption and subsequent elimination of everolimus may be influenced by drugs 
that act on CYP3A4 and/or PgP.  In vitro, everolimus is a competitive inhibitor of CYP3A4 
and a mixed inhibitor of CYP2D6. 
Known and theoretical interactions with selective inhibitors and inducers of CYP3A4 and PgP 
are described in the Table below. 
 
CYP3A4 and PgP inhibitors that may increase everolimus concentrations: CYP3A4 or PgP 
inhibitors may increase blood levels of everolimus by decreasing the metabolism or efflux of 
everolimus from intestinal cells. 
CYP3A4 and PgP inducers that may decrease everolimus concentrations: Substances that are 
CYP3A4 and PgP inducers may decrease blood levels by increasing everolimus metabolism or 
efflux of everolimus from intestinal cells.

Use with caution when concomitant 
administration with moderate CYP3A4 or 
PgP inhibitors cannot be avoided. If co-
administration with a moderate CYP3A4 or 
PgP inhibitor is required, a dose reduction 
to 5 mg daily and 5 mg every other day may 
be 
considered. 
However, 
there 
is 
insufficient

CYP3A4 inducers. If co-administration 
with a strong CYP3A4 inhibitor is required, 
an everolimus dose increase of 10 mg daily 
up to 20 mg daily, using a 5 mg step 
increase, is applied on day 4ième and day 
8ième after initiation of inducer therapy. This 
dose of everolimus is established to adjust 
the AUC to the range of values observed 
without inducer. However, there are no 
clinical data available with this dose 
adjustment. When treatment with the potent 
inducer is stopped, the dose of everolimus 
should be returned to the dose used prior to 
initiation of concomitant administration.

treatment 
 
The use of live vaccines should be avoided during everolimus treatment (examples of live 
vaccines: intranasal influenza vaccine, measles vaccine, mumps vaccine, rubella vaccine, oral 
polio vaccine, BCG (Bacillus Calmette-Guérin), varicella vaccine, and Typhoid Ty21a vaccine) 
 
 
4- Treatment with somatostatin analogues  
 
In patients who were receiving somatostatin analogue therapy for symptomatic purposes prior 
to embolization or chemoembolization, this therapy should be continued after embolization or 
chemoembolization unless determined by the investigator. In the absence of carcinoid 


FFCD 1104-EVACEL

V1.2 -18.08.2015 amendment 5 
syndrome, somatostatin analogue therapy is not permitted after embolization or 
chemoembolization. 
 
VII. 
EXPECTED TOXICITIES AND DOSE ADJUSTMENT 
 
1. 
Dose adjustment after the first embolization or chemoembolization 
 
No dose adjustment of doxorubicin or streptozotocin is planned for chemoembolization 
sessions. There are no plans to adjust the dose of lipiodol for embolization sessions. 
 
Embolization or chemoembolization will only be performed if hematological, renal and hepatic 
functions are satisfactory i.e. if: 
- 
PNN > 1.5 109 /L, 
- 
Platelets > 75 x 109 /L 
- 
Hemoglobin > 10 g/dL 
- 
INR < 1.3N or < 3 on anticoagulants or PT > 50  
- 
Creatinine level < 1.5N 
- 
Total bilirubin < 1.5N  
- 
ASAT, ALAT < 5N 
- 
PAL < 5N  
In case of grade 3 or 4 non-hematological toxicity attributable to the first embolization or 
chemoembolization session, no further embolization or chemoembolization is performed. Only 
everolimus will be continued for a maximum of 24 months.  
 
2. 
Everolimus dose adjustment 
 
All toxicity will be assessed according to the NCI-CT v4.0 scale (Appendix 4). 
The rules for everolimus dose adjustment in case of observed hematological and non-
hematological toxicities are defined in Tables 1.1, 1.2.   
All interruptions or changes to the study drug must be recorded 
 
Monitoring of suspected everolimus toxicity 
Patients whose treatment is temporarily or permanently discontinued due to an adverse event 
or laboratory abnormality suspected to be related to everolimus should be monitored at least 
weekly until the adverse event resolves or returns to grade 1. If the patient's treatment is to be 
delayed for more than 21 days from the day of the next scheduled dose, the patient should be 
excluded from the study.

Known adverse reactions to everolimus  
 
-The most common grade -34 adverse events -(frequency ≥ 2% in at least one pivotal study) 
were anemia, fatigue, diarrhea, infections, stomatitis, hyperglycemia, thrombocytopenia, 
lymphopenia, neutropenia, hypophosphatemia, hypercholesterolemia, diabetes mellitus, and 
pneumonitis. Grades follow the CTCAE version 4.0 classification. 
Everolimus has immunosuppressive properties and may predispose patients to bacterial, fungal, 
viral or protozoal infections, including infections with opportunistic pathogens. Localized and 
systemic infections, including pneumonia, other bacterial infections, invasive fungal infections 
such as aspergillosis or candidiasis, and viral infections, including cases of hepatitis B 
reactivation, have been described in patients treated with everolimus. Some of these infections 
have been severe (e.g., leading to respiratory or hepatic failure), sometimes with fatal outcome. 
Physicians and patients should be aware of the increased risk of infection with everolimus. Pre-
existing infections should be treated before starting everolimus therapy.  During treatment with 
everolimus, vigilance for signs and symptoms of infection should be exercised; if an infection 
is diagnosed, appropriate treatment should be initiated as soon as possible and temporary or 
permanent discontinuation of everolimus should be considered. If a diagnosis of invasive 
systemic fungal infection is made, everolimus must be discontinued and appropriate antifungal 
therapy initiated. 
Hypersensitivity reactions with symptoms including anaphylaxis, dyspnea, flushing, chest pain, 
or angioedema (e.g., swelling (edema) of the airways or tongue, with or without respiratory 
failure) have been observed with everolimus. 
Hyperglycemia has been reported in clinical trials.  It is recommended that fasting blood 
glucose be monitored prior to initiation of everolimus therapy and periodically thereafter. 
Optimal glycemic control should be achieved prior to initiating everolimus therapy in a patient. 
Mouth ulcers, stomatitis and oral mucositis have been observed in patients treated with 
everolimus. In these cases, topical treatments are recommended, but alcohol or hydrogen 
peroxide mouthwashes should be avoided. 
Elevations in serum creatinine, usually mild, have been reported in clinical trials. It is 
recommended that renal function be monitored before starting everolimus therapy and 
periodically thereafter. 
Decreases in hemoglobin, lymphocytes, platelets and neutrophils have been reported in clinical

V1.2 -18.08.2015 amendment 5 
trials. It is recommended that complete blood counts be monitored prior to the initiation of 
everolimus therapy and periodically thereafter. 
The use of live vaccines and close contact with individuals who have received live vaccines 
should be avoided during treatment with everolimus. 
Hypophosphatemia, hypomagnesemia, hyponatremia and hypocalcemia have been reported.  
c. 
Management of stomatitis/oral mucositis/aphthae  
Oral stomatitis/mucositis/ mouth ulcers due to everolimus should be treated with local 
symptomatic therapy. It should be noted that investigators in previous trials have described oral 
toxicities associated with everolimus in terms of mouth ulcers rather than mucositis or 
stomatitis. If your examination reveals canker sores rather than more general inflammation of 
the mouth, please classify the adverse event as such. Please follow the template below for 
treatment of oral stomatitis/mucitis/aphthas: 
1. For mild toxicity (Grade 1), use conservative measures such as alcohol-free mouthwash 
or salt water mouthwash (0.9%) several times a day until resolved. 
2. For more severe toxicity (grade 2, in which case patients are able, despite pain, to maintain 
adequate oral nutrition, or grade 3 in which case patients cannot maintain adequate oral 
nutrition), the proposed treatments are analgesic topical oral treatments (i.e., local 
anesthetics such as benzocaine, butylaminobenzoate, tetracaine hydrochloride, 
menthol, or phenol) with or without topical corticosteroids, such as triamcinolone 
acetonide 0.1% gingival paste (Orabase Kenalog® ). 
3. Agents containing hydrogen peroxide, iodine and thyme derivatives may tend to exacerbate 
mouth ulcers. It is best to avoid these agents. 
4. Antifungal agents should be avoided unless a fungal infection has been diagnosed. In 
particular, systemic imidazole antifungal agents (ketoconazole, fluconazole, itraconazole, 
etc.) should be avoided in all patients as they are potent inhibitors of everolimus 
metabolism, resulting in higher everolimus exposures. Therefore, topical antifungal agents 
are preferable if an infection is diagnosed. Similarly, antiviral agents such as acyclovir 
should be avoided unless a viral infection is diagnosed. 
d. 
Management of hyperlipidemia and hyperglycemia  
Hyperlipidemia and hypertriglyceridemia should be treated according to local best clinical 
practice.  
e. 
Management of non-infectious lung disease 
Non-infectious pneumonitis is a class effect of rapamycin derivatives.  Non-infectious lung 
disease (including interstitial lung disease) has also been described in patients treated with 
everolimus. A diagnosis of non-infectious lung disease should be considered in patients 
presenting with non-specific respiratory signs and symptoms such as cough or dyspnoea, 
hypoxia, pleural effusion, and when infectious, neoplastic or other non-drug causes have been 
excluded by appropriate investigations. Patients should be asked to report promptly any new or 
worsening respiratory symptoms.  
Patients with radiological changes suggestive of non-infectious lung disease with few or no 
symptoms may continue everolimus therapy without a change in dosage. In the presence of 
moderate symptoms (Grade 2), discontinuation of treatment should be considered until 
symptoms improve. Administration of corticosteroids may be indicated. Everolimus may be 
reintroduced at a reduced dose until recovery to Grade 1 or higher.  
When symptoms of non-infectious lung disease are severe (Grade 3), everolimus treatment 
should be discontinued and corticosteroids may be indicated until clinical symptoms resolve. 
Everolimus treatment may be reintroduced at a reduced dose depending on individual clinical 
circumstances.

Management of reactivation /flare-up of hepatitis  
In cancer patients with hepatitis B virus, either carrier or chronic, the administration of antivirals 
during cancer therapy has been shown to reduce the risk of hepatitis B virus (HBV) reactivation 
and associated morbidity and mortality (Loomba et al. 2008). 
• Monitoring and prophylaxis for hepatitis B reactivation

should restart the study drug at the same dose after resolution. 
Antiviral therapy should be continued for at least 4 weeks after 
the last dose of study drug is administered.  
In case of resolution within > 28 days patients should 
discontinue study drug, but continue antiviral therapy for at least 
4 weeks after the last dose of study drug. 
* All hepatitis B reactivations should be recorded as a Grade 3 adverse event (CTCAE v 4.0 
Other Adverse Events Associated with Metabolic or Biological Abnormalities: Viral 
Reactivation), unless the investigator considers them life-threatening in which case they should 
be recorded as a Grade 4 adverse event (CTCAE v 4.0 Other Adverse Events Associated with 
Metabolic or Biological Abnormalities: Viral Reactivation). The date of viral reactivation is the 
date on which both the DNA and ALAT criteria are met (e.g., for a patient with HBV DNA 
positive on 01-01-10 and an ALAT level ≥ 5 x ULN on 01-04-10, the date of viral reactivation 
is 01-04-10). 
• Hepatitis C Outbreak Surveillance 
The following two categories of patients should be monitored every 6 weeks for HCV 
reactivation: 
- 
Patients with detectable HCV RNA by PCR analysis in basal state. 
- 
Patients with a known history of hepatitis C virus (HCV) infection, despite a negative 
baseline viral load test (including those who have been treated and considered "cured")

VIII. 
PATIENT MONITORING DURING TREATMENT AND 
AFTER WITHDRAWAL OF TREATMENT 
 
1. 
Monitoring during treatment 
 
Within 7 days prior to each embolization or chemoembolization session   
 
o Clinical assessment: weight, general condition (WHO) 
o Evaluation of the tolerance of the previous embolization or chemoembolization 
o Biological check-up:  
o CBC-platelets 
o INR, aPTT, creatinine, bilirubin (total, conjugated), AST, ALT, PAL 
 
NB: An abdominal CT scan may be performed if necessary for technical reasons before the 2nd 
embolization or chemoembolization session. Caution: this imaging should not be used to 
evaluate the response to treatment of metastases. 
 
Every 3 months (+/- 1 week) from the date of the first embolization or 
chemoembolization (except DNA and ARC monitoring for positive serology)  
 
o Clinical assessment: WHO, weight, evaluation of side effects 
o Bioassay:  
• 
CBC/platelets, urea and creatinine + calculated creatinine clearance 
(Cockcroft formula), blood ionogram 
• 
INR, aPTT, albumin, alkaline phosphatase, AST, ALT, bilirubin (total 
and conjugated), gamma-GT 
• 
Serum cholesterol and triglycerides 
• 
Fasting blood glucose and HbA1c 
• 
Chromogranin A, urinary 5HIAA 
o If HBV positive, monitor DNA approximately every 3 weeks or 6 weeks depending on 
the result (see Table 2-2)   


FFCD 1104-EVACEL 
 
 
 
 
28/36 
V1.2 -18.08.2015 amendment 5 
o If HCV positive, monitor RNA every 6 weeks (see Table 2.3)  
o Morphological assessment: triphasic thoracic-abdominal-pelvic CT scan with target 
measurement according to RECIST V1.1 criteria (Appendix 3). Evaluation CT scans 
should be performed in the same center as the initial examination 
 
NOTE: Patients whose treatment is temporarily or permanently discontinued due to an 
adverse event or laboratory abnormality suspected to be related to everolimus should be 
monitored at least weekly until the adverse event resolves or returns to Grade 1 
2. 
Post-treatment monitoring protocol 
 
- 
After discontinuation of treatment for hepatic progression  
o After hepatic progression, the clinical, biological and morphological 
monitoring of the patient will be left to the investigator's discretion 
 
- 
After discontinuation of treatment for a reason other than hepatic progression 
(e.g. toxicity, extra-hepatic progression, patient's wish, : 
o Morphological surveillance: CT every 3 months until liver progression occurs, 
according to the same modalities as the initial morphological evaluation 
(triphasic thoraco-abdomino-pelvic CT with target measurement according to 
RECIST V1.1 annex 3) 
 
IX. 
STOP PROCESSING THE STUDY  
 
The processing of the study will be stopped in case of: 
- Investigator's decision 
- Major toxicity requiring discontinuation of treatment (despite protocol adaptations) 
- Serious or unexpected event requiring discontinuation of protocol treatment 
- Disease progression (hepatic, extra-hepatic, clinical) 
- Patient refusal 
- Death of the patient 
 
X. 
CENTRALIZED PROOFREADING OF TDM  
 
To address the primary endpoint of efficacy of everolimus treatment after embolization or 
chemoembolization, a centralized review of morphological examinations of the inclusion 
workup and follow-ups will be performed by an independent review committee. 
 
To do this, make a copy of the imaging to be kept in the patient's file. The FFCD CRA in charge 
of your center will make an anonymized copy of the CD ROM and send the imaging to the 
FFCD imaging platform.  
 
XI. 
  MANAGEMENT OF SERIOUS ADVERSE EVENTS (SIA)  
 
Security assessment parameters 
Safety will be assessed by evaluating the general and clinical condition of the patients and by 
collecting events occurring between visits during consultations, by regular blood tests. 
Toxicities will be assessed using the NCI-CTC-AE version 4.0 toxicity scale (see Appendix 4).

Definitions 
 
a. Adverse Event (AE) 
An adverse event is a harmful occurrence in a person who is a subject of biomedical research, 
whether or not the occurrence is related to the research or the product being investigated. 
 
All adverse events will be recorded in the observation book on the pages provided. 
 
b. Serious Adverse Event (SAE) 
A serious adverse event is any event that   
• Resulting in death, 
• Life-threatening, 
• Leading to hospitalization or prolonged hospitalization, 
• Causing permanent disability or severe temporary incapacity, 
• Causing a birth defect, fetal malformation or abortion, 
• Medically significant   
The terms disability and incapacity correspond to any temporary or permanent physical or 
psychological handicap, clinically significant and affecting the physical activity and/or quality 
of life of the patient. 
 
Any clinical event or laboratory result considered serious by the investigator and not 
corresponding to the severity criteria defined above is considered medically significant. They 
may put the patient at risk and require medical intervention to prevent an outcome 
corresponding to one of the above mentioned severity criteria (e.g. overdose, second cancers, 
pregnancies and new events may be considered as medically significant). 
 
Pregnancy is an exclusion criterion in this trial. However, if a pregnancy is discovered after 
inclusion, the patient must be excluded from the trial. The sponsor should be informed without 
delay via the serious adverse event reporting form (no severity criteria should be checked). The 
patient should be followed until the outcome of the pregnancy and this outcome, whatever it 
may be, should be reported to the sponsor. 
 
Hospitalizations included in the protocol will not be considered an SAE. 
 
c. Undesirable Effect  
Any noxious and undesired response to an investigational drug at any dose or to any 
investigational component. The adverse reaction is serious if it meets the severity criteria (see 
above). 
 
d. Unexpected Serious Adverse Effect 
An unexpected serious adverse reaction is an event that is not mentioned, or that differs in 
nature, intensity, or evolution from the product's reference document (Investigator's Brochure 
or RCPs). 
 
In this essay the reference documents will be: 
• For everolimus, the Summary of Product Characteristics for Afinitor® (Appendix 6) 
 
The versions of the Investigator's Brochure and PCR (used for the definition of expected or 
unexpected everolimus) will be the latest available on the anniversary date of the start of the 
trial. 
 
What to do  
 


FFCD 1104-EVACEL 
 
 
 
 
30/36 
V1.2 -18.08.2015 amendment 5 
The investigator informs the sponsor of all Serious Adverse Events (Expected and Unexpected), 
whether or not attributable to the research, that occur during treatment and within 30 days of 
the last treatment administration.  
 
All Delayed Serious Adverse Events (occurring after this 30-day period) considered reasonably 
related to the protocol treatment(s) or research should be reported without time limitation. 
 
The report is made by faxing the "notification of a serious adverse event" form (Appendix 7), 
documented as precisely as possible, dated and signed, within 24 working hours of their 
discovery to the FFCD's Randomization Management Analysis Center (CRGA): by fax to 
03 80 38 18 41 
 
Modalities and duration of follow-up of individuals following the occurrence of adverse 
events 
The investigator is responsible for appropriate medical follow-up of patients until resolution or 
stabilization of the effect or until the patient's death. This may sometimes mean that this follow-
up extends beyond the patient's discharge from the trial. 
 
He/she transmits the additional information to the sponsor using an SAE reporting form 
(checking the Follow-up No. X box to specify that it is a follow-up report and not an initial 
report) within 24 hours of obtaining it. It also forwards the last follow-up to the resolution or 
stabilization of the SAE.  
He keeps the documents concerning the suspected adverse reaction in order to allow, if 
necessary, to complete the information previously transmitted. 
 
 
XII. 
STATISTICAL ANALYSIS 
 
 
1. 
Provisional timetable for the study 
 
The end of the trial will be 4 years after the inclusion of the last patient included. For the 
purposes of the study, the follow-up time for patients will be 24 months after inclusion. 
 
The rate of inclusion is estimated at 3 patients per month, so the duration of inclusion is 24 
months. 
 
The study duration to meet the primary and secondary endpoint is 24 months. 
 Six months will be required to clean the base and perform the analysis + final report (March 
2015).  
 
Expected start date of inclusions: November 2012 
Expected completion date of inclusion: April 2016  
Primary endpoint analysis: April 2018 
Theoretical end of study: January 2019 
 
2. 
Analysis  
Main criterion  
The primary endpoint will be to assess liver progression (death will be considered as 
progression) during the 24 months of everolimus treatment according to RECIST V1.1 criteria 
(Appendix 3). 


FFCD 1104-EVACEL 
 
 
 
 
31/36 
V1.2 -18.08.2015 amendment 5 
 
The time to progression-free survival (based on review or on the opinion of the investigator if 
review is not possible) will be defined as the time interval between the date of inclusion and the 
date of liver progression or death (regardless of cause). For living patients without hepatic 
progression, the time interval between the date of inclusion and the date of last morphological 
evaluation will be taken. 
 
Secondary criteria  
The secondary endpoints will be:  
- 
Progression-free survival (hepatic or non-hepatic) at 24 months 
- 
Overall survival at 24 months 
- 
Tolerance of the treatment during the 24 months of treatment  
 
Progression-free survival will be defined as the time interval between the date of inclusion and 
the date of progression (hepatic or non-hepatic) as assessed by RECIST V1.1 criteria or death 
(regardless of cause) or the date of the last morphological assessment for patients alive without 
progression. 
 
Overall survival will be defined as the time interval between the date of inclusion and the date 
of death regardless of the cause of death or the date of last news for living patients. 
 
Tolerance to treatment will be assessed by: 
- duration of treatment, doses received, dose reductions and deferrals 
- Toxicities collected at each monthly visit, and described according to NCI-CTC version 
4.0 criteria; Grade 3, Grade 4 and Grade 5 toxicities will be reviewed. 
- the number and description of SAEs 
- the evolution of the WHO performance index. 
 
Calculation of the number of subjects needed 
According to the literature, the median progression-free survival after embolization or 
chemoembolization ranges from 15 to 19 months with a progression-free survival rate of 
approximately 35%. As there is no information on progression-free survival in the literature, 
the hypotheses were built on the progression-free survival data. 
The assumptions used to calculate the number of subjects are as follows: 
H0: a 24-month progression-free survival rate of less than 35% is not acceptable  
H1: A 24-month liver progression-free survival rate greater than 35% would demonstrate the 
utility of everolimus therapy with an expected 24-month liver progression-free survival rate of 
50%, 
To obtain a power of 80% with a first-species risk of 5% (one-sided), it is required to include 
68 patients according to the assumptions established above (using the exact binomial 
distribution). 
Taking into account a rate of lost to follow-up or patients not evaluable for any reason except 
death, 72 patients will be included. 
3.

Populations of analysis 
 


FFCD 1104-EVACEL 
 
 
 
 
32/36 
V1.2 -18.08.2015 amendment 5 
Patients included in the study will be described (ITT) as well as patients not evaluable for the 
primary endpoint.   
 
A patient is considered evaluable if he or she has received at least one dose of everolimus and 
one evaluation. 
 
All efficacy analyses will be performed on a modified intention-to-treat basis (evaluable 
patients) included in the study regardless of eligibility criteria and treatment received. 
 
Tolerability population: the ITT population that received at least one dose of the treatments. 
 
In all cases of discontinuation, the patient remains in the intention-to-treat analysis. There is no 
exclusion period for a subsequent therapeutic trial. 
 
Main analyses 
 
A statistical analysis plan will be written prior to freezing the database. 
The description of clinical and medical variables will be done using percentages (95% 
confidence interval) and mean (standard deviation) and median (Min-Max) as well as the inter-
quartile range (Q1-Q3). 
 
Survivals and times will be estimated by the Kaplan Meier (KM) method. They will be 
described by medians and rates at different time points with their 95% confidence intervals. 
Median follow-up time will be calculated using the reverse Kaplan Meir method. 
 
The results for the primary endpoint will also be described by a Water Fall plot representing for 
each patient the percentage change at 24 months in liver metastasis size since the measurement 
at inclusion according to the response according to the RECIST V1.1 criteria. 
 
The time to onset of grade 3/4/5 toxicity will be estimated using the Kaplan Meier method.

Independent committees 
 
An independent committee will be formed and will include at least: two physicians (onco-
gastroenterologists), a statistician, a pharmacovigilance expert. The independent committee 
may meet at any time during the protocol when deemed necessary by the Sponsor. 
XIII. 
JUSTIFICATION OF THE TEST  
 
Neuroendocrine tumors (NETs) are a heterogeneous group of rare tumors. The prevalence of 
these tumors is estimated to be between 0.4 and 1 per 100,000 inhabitants per year. In the 
gastrointestinal tract, the most frequent locations are the appendix (19%), the small intestine 
(15%) and the rectum (11%). Neuroendocrine tumors of the small intestine mainly affect young 
adults between 30 and 35 years of age, while those of the colon tend to occur around 60 years 
of age [[1]. 
 
Treatment of digestive endocrine tumors 


FFCD 1104-EVACEL 
 
 
 
 
33/36 
V1.2 -18.08.2015 amendment 5 
 
There are many therapeutic options, and the choice of treatment depends primarily on the 
location of the primary tumor, the stage of extension, and the tumor's progression [[2]. Given 
the great variability of cases, it is difficult to establish a precise decision tree for the treatment 
of digestive NETs. In all cases, the decision should be made after multidisciplinary discussion. 
Symptomatic management of hormonal hypersecretion is imperative and should be initiated 
without waiting for the extension workup. Surgery, the only curative treatment, should always 
be discussed initially, and secondarily, after obtaining a therapeutic response. Surgical removal 
of the primary tumor is usually recommended, even in cases of advanced NET. In the metastatic 
situation, the therapeutic indications must be discussed taking into account the location of the 
primary tumor and the metastases, the cellular differentiation, the evolution with evaluation of 
the speed of growth of the metastases. In the case of well-differentiated NETs with little 
progression, an initial surveillance can be proposed with a first evaluation at a few weeks to 
assess the tumor evolution. 
If the tumor is slowly progressive (tumor stability without new localization), monitoring, 
possibly associated with treatment with somatostatin analogues, may be proposed. If the tumor 
is progressive (morphological progression or new metastatic sites), antitumor treatment should 
be considered. In the case of NET of the digestive tract, which is not very chemosensitive, 
(chemo)-embolization in case of isolated or predominant liver metastases is often the preferred 
option. 
 
Place of (chemo)embolization 
 
The principle of intra-arterial chemoembolization is to combine chemotherapy administered via 
the hepatic intra-arterial route with embolization [[3]. As metastases are, contrary to normal 
liver, mainly vascularized by the arterial route, this approach allows to induce a targeted anoxia, 
potentiated by the administration of a cytotoxic agent. 
Chemoembolization is effective in controlling clinical manifestations related to hormonal 
hypersecretion, especially during carcinoid syndrome, in 70 to 100% of patients depending on 
the series. 
The ENETS-01 trial, the only prospective randomized trial that compared embolization and 
chemoembolization, included only 26 patients. There was no difference in progression-free 
survival at 24 months (the primary endpoint) between the chemoembolization (38%) and 
embolization (44%, p=0.9) groups[4]. In the larger retrospective non-randomized series, 
progression-free survival rates are not always specified [5, 6, 7]. In the MD Anderson study (81 
patients), the 24-month progression-free survival rate was 35% with a median progression-free 
survival of 17 months. [6]. In a French study, the median progression-free survival was 14.5 
months with a 24-month progression-free survival rate of about 35% in 67 patients [7]. 
A post-embolization syndrome (fever, abdominal pain, nausea, vomiting, hepatic cytolysis) is 
frequent and requires appropriate symptomatic treatment. The possibility of an acute carcinoid 
crisis justifies the prescription of a treatment with somatostatin analogues. These techniques are 
contraindicated in case of biliary-digestive anastomosis or biliary prosthesis because of a major 
risk of infectious complication with hepatic abscess. Portal vein thrombosis and hepatocellular 
insufficiency are also contraindications. 
 
 
Rationale for antiangiogenic therapy after (chemo)embolization 
 
Digestive NETs are characterized by their hypervasculariation. Endocrine tumor cells secrete 
excess VEGF which is likely to play an important role in the angiogenic process associated 
with endocrine tumorigenesis [8, 9]]. However, the mechanisms that regulate the angiogenic 
process associated with endocrine tumorigenesis in digestive NETs remain poorly understood.

Embolization stimulates angiogenesis with an increase in circulating VEGF levels [10] levels, 
and the main mechanism associated with a progressive recovery after (chemo)embolization is 
tumor revascularization from collateral vessels. In this context, a treatment with antiangiogenic 
action administered after (chemo)embolization could improve tumor control. A recent phase II 
study evaluated sunitinib therapy in this setting with encouraging results [10].  
 
Everolimus 
 
Inhibitors of the mTOR pathway have antiangiogenic activity, which partly explains their 
antitumor effect in vitro and in vivo [11]. Regarding everolimus, promising initial results have 
led to a development program in digestive NETs. In a phase II study, Yao et al. reported the 
use of everolimus combined with delayed octreotide in 60 patients with well differentiated NET 
[12]. The objective response was 30% in the 30 patients treated with the 10-mg dose versus 
13% for patients treated with 5 mg. Among patients with "carcinoid" tumors, the objective 
response rate was 17%, with stabilization achieved in 80% of patients, at the cost of moderate 
side effects. This study led to the selection of the 10 mg everolimus dose for further 
development of the product in the RADIANT I, II and III studies [12, 13, 14]. Only the 
RADIANT II study involved NET of the gastrointestinal tract [13]. This international 
multicenter phase III study randomized everolimus (10 mg/d) to placebo, combined in both 
arms with octreotide LP30 mg/28 d. Four hundred and thirty patients with documented 
progression within 12 months prior to inclusion were included. One-third of the patients had 
been previously treated with chemotherapy and nearly 80% with a delayed somatostatin 
analogue. Progression-free survival was 16.4 months in the everolimus plus delayed octreotide 
arm versus 11.3 months in the placebo plus delayed octreotide arm (HR = 0.77; 95% CI = 0.59-
1.00; p = 0.026) in centralized readout (primary objective of the trial), not statistically 
significant according to the study analysis design since the expected predefined p was 0.0246. 
The center-read analysis (12.0 months versus 8.6 months, HR = 0.78; 95% CI = 0.62-0.98; p = 
0.018) and after predefined statistical adjustments (HR = 0.60; 95% CI = 0.44-0.84; p = 0.0014), 
which were secondary objectives of the trial, supported the superiority of everolimus. The 
interim analysis of overall survival showed no difference between the two groups (HR = 1.22; 
95% CI = 0.91-1.62; p = 0.908). The safety profile of this molecule is quite acceptable, with 
mainly grade 1-2 toxicities and less than 7% grade 3-4 toxicities.

3 Introduction 
 
3.1 Rationale for the study 
 
Neuroendocrine tumors (NETs) are a heterogeneous group of rare tumors (estimated prevalence between 
0.4 and 1 per 100,000 population per year).  
Treatment of digestive endocrine tumors 
There are numerous therapeutic options and the choice of treatment depends essentially on the location of 
the primary tumor, the stage of extension and the tumor's evolution. In all cases, the decision must be taken 
after multidisciplinary discussion. Symptomatic management of hormonal hypersecretion is imperative. 
Surgical removal of the primary tumor is usually recommended. In the case of well-differentiated NETs with 
little progression, initial surveillance may be proposed with an evaluation of the tumor's evolution. If the 
tumor is slowly progressive (tumor stability without new localization), surveillance, possibly associated 
with treatment with somatostatin analogues, may be proposed. If the tumor is progressive (morphological 
progression or new metastatic sites), antitumor treatment should be considered. In the case of NET of the 
digestive tract, which is not very chemosensitive, (chemo)embolization in case of isolated or predominant 
liver metastases is often the preferred option. 
Place of (chemo)embolization 
The principle of intra-arterial chemoembolization is to combine intra-arterial hepatic chemotherapy with 
embolization. As metastases are mainly vascularized by the arterial route, this approach allows to induce a 
targeted anoxia. Chemoembolization is effective in controlling clinical manifestations related to hormonal 
hypersecretion. The ENETS-01 trial, the only prospective randomized trial comparing embolization and 
chemoembolization (26 patients included), showed no difference in progression-free survival at 24 months 
between the chemoembolization (38%) and embolization (44%) groups. In the MD Anderson study (81 
patients), the 24-month progression-free survival rate was 35%. In a French study (67 patients), the 24-
month progression-free survival rate was about 35%.  
Rationale for antiangiogenic therapy after (chemo)embolization 
Digestive NETs are characterized by their hypervasculature. Tumor endocrine cells secrete excess VEGF 
which is likely to play an important role in the angiogenic process associated with endocrine tumorogenesis. 
Embolization stimulates angiogenesis with an increase in circulating VEGF levels and the main mechanism 
associated with a progressive recovery after (chemo)embolization is tumor revascularization from 
collateral vessels. Therefore, treatment with antiangiogenic action after (chemo)embolization could 
improve tumor control.  
Everolimus 
Inhibitors of the mTOR pathway have antiangiogenic activity, which explains in part their antitumor effect. 
In the phase II study by Yao et al., the everolimus dose of 10 mg was retained for further development. Only 
the phase III RADIANT II study concerned NET of the digestive tract. This study randomized 430 patients 
between everolimus (10 mg/d) and placebo, combined in both arms with octreotide LP30mg/28d. 
Progression-free survival was 16.4 months in the everolimus arm versus 11.3 months in the placebo arm 
(HR = 0.77; 95% CI = 0.59-1.00; p NS) on centralized review. The center-read analysis (12.0 months versus 


 
Statistical Analysis Plan - Final Analysis - FFCD 1104 -EVACEL - Version 1.4 : 19/06/18 
Page 7 on 20 
8.6 months, HR = 0.78; 95% CI = 0.62-0.98; p S) supported the superiority of everolimus with a very 
acceptable safety profile.  
 
 
3.2 Objectives of the trial 
 
3.2.1 
Objective main 
The primary objective of the study is to determine whether treatment with everolimus for 24 months 
prolongs progression-free survival according to RECIST 1.1 criteria. The primary endpoint will be 
progression-free survival at 24 months in patients receiving hepatic embolization or chemoembolization 
followed by everolimus therapy. 
 
3.2.2 
Secondary objectives 
The secondary objectives of the study are to evaluate: 
• 
Progression-free survival at 24 months (hepatic and non-hepatic) 
• 
Overall survival at 24 months 
• 
Tolerance of the treatment during the 24 months of treatment   
 
3.2.3 
Exploratory analyses 
An exploratory analysis is planned to: 
• Search for factors predictive of progression-free survival and/or overall survival 
• To compare liver progression-free survival between embolization alone and chemoembolization.

5 Experimental design 
 
5.1 Scheme of the study 
This is a single-arm, multi-center Phase II trial.  
 
5.2 Treatment arm 
There is a single study treatment arm consisting of: 
- 
1 to 2 embolization or chemoembolization sessions (sessions spaced 4 to 8 weeks apart).  
- 
10 mg/day everolimus (started 7 days after embolization or chemoembolization) 
The maximum treatment period is 24 months. 
 
5.3 Randomization and blinding  
The trial is an open-label trial. There is no randomization in this trial. 


 
Statistical Analysis Plan - Final Analysis - FFCD 1104 -EVACEL - Version 1.4 : 19/06/18 
Page 10 on 20 
5.4 Chronological sequence 
Each patient will follow the chronological sequence described below: 
 
 
5.5 Justification of the number of subjects needed 
According to the literature, the median progression-free survival after embolization or chemoembolization 
ranges from 15 to 19 months with a progression-free survival rate of approximately 35% at 24 months. As 
there is no information on hepatic progression-free survival in the literature, the hypotheses were built on 
the progression-free survival data. 
The assumptions used to calculate the number of subjects are as follows: 
• H0: a 24-month progression-free survival rate of less than 35% is not acceptable  
• H1: A 24-month liver progression-free survival rate of more than 35% would demonstrate the utility 
of adjuvant everolimus therapy with an expected 24-month liver progression-free survival rate of 
50%,

Page 11 on 20 
To obtain a power of 80% with a first-species risk of 5% (one-sided), it is required to include 68 patients 
according to the assumptions established above (using the exact binomial distribution). 
Taking into account a 5% rate of lost to follow-up or patients who cannot be evaluated for any reason except 
death, 72 patients will be included. 
 
5.6 Steps of the test 
 
5.6.1 
Analysis Final 
The final analysis will be performed 24 months after the inclusion of the 72ème patient. The point date for 
the analysis is therefore: 01/09/2017 
Out of 68 evaluable patients, if 31 or more patients are alive without liver progression at 24 months, the 
treatment will be declared worthwhile. 
 
5.6.1 
Late analysis 
Not applicable. 
 
5.7 Judging criteria 
 
5.7.1 
Main criterion 
The primary endpoint is the rate of living patients without liver progression 24 months after inclusion. 
Hepatic progression is defined according to RECIST V1.1 criteria and is based on centralized review (or on 
the investigator's opinion in case of impossible review). 
 
5.7.2 
Secondary endpoints of effectiveness 
5.7.2.1 
Rate of living patients without liver progression in mRECIST at 24 months 
The rate of living patients without liver progression 24 months after inclusion will also be described 
according to mRECIST criteria and based on centralized review. 
5.7.2.2 
Survival without liver progression 
It is defined as the time from the date of inclusion to the date of first hepatic progression (based on 
centralized review or on the investigator's opinion in case of impossible review) or the date of death 
(regardless of cause). Living patients without hepatic progression will be censored at the point date or the 
date of last morphological evaluation. 
Live patients for whom no morphological evaluation is available will be censored at inclusion date + 1 day. 
 
5.7.2.3 
Progression-free survival 
It is defined as the time between the date of inclusion and the date of first hepatic or extrahepatic 
progression (based on centralized review or on the investigator's opinion in case of unavailable review) or 


 
Statistical Analysis Plan - Final Analysis - FFCD 1104 -EVACEL - Version 1.4 : 19/06/18 
Page 12 on 20 
the date of death (regardless of cause). Patients alive without progression will be censored at the point date 
or the date of last morphological evaluation. 
Live patients for whom no morphological evaluation is available will be censored at inclusion date + 1 day. 
5.7.2.4 
Overall survival 
It is defined as the time between the date of inclusion and the date of death (regardless of cause). Patients 
lost to follow-up or alive at the time of analysis will be censored at the date of last news. 
 
5.7.3

▪ 
Best response under treatment (based on centralized review) 
▪ 
The administration of G-CSF 
 
5.7.2 
Exploratory analyses 
▪ 
An analysis of the predictive factors for overall survival and progression-free survival will be 
performed; 
▪ 
In an exploratory manner, the progression-free survival between embolization alone and 
chemoembolization will be compared (if the number of patients in each group is sufficient). 
 
6 Study population for analysis 
 
6.1 Definition of Analysis Populations 
 


 
Statistical Analysis Plan - Final Analysis - FFCD 1104 -EVACEL - Version 1.4 : 19/06/18 
Page 13 on 20 
6.1.1 
Intent-to-treat (ITT) population 
The intention-to-treat population is defined as all patients included in the study, regardless of eligibility 
criteria and treatment received. All analyses will be performed on an intention-to-treat basis, unless 
specifically mentioned for certain criteria. 
 
6.1.2 
Population of analysis for primary endpoint (PC) 
The analysis population for the primary endpoint is defined as the ITT population of evaluable patients. A 
patient is considered evaluable if he or she has received at least one dose of everolimus and at least one 
treatment-related imaging. 
A patient who dies (from any cause after treatment) or progresses in liver function before 24 months is 
evaluable and considered a failure for the primary endpoint. 
Patients without a 24-month evaluation will be reviewed according to the following rules:  
- 
If the patient has a later assessment (27 months or more) and is not progressing at that time, then 
they will be considered progression-free at 24 months  
- 
The other patients will be reviewed at a medical review to decide, in view of the patient's entire 
file, whether they can be considered as failed or as truly non-evaluable (a rate of 5% of additional 
patients has been planned for these situations).  
 
A listing of patients excluded from the CP population will be provided with the reasons for their exclusion. 
  
6.1.1 
Population per protocol (PP) 
The per-protocol population is defined as all patients included in the study without major protocol deviation 
(i.e. meeting the criterion "Endocrine tumor of the gastrointestinal tract"), having at least one 
(chemo)embolization and at least 1 month of everolimus treatment (started within 30 days post-HEC). 
A listing of patients excluded from the PP population will be provided with the reasons for exclusion. 
 
6.1.2 
Population for tolerance analysis (SP) 
It is defined as the ITT population that received at least one dose of everolimus. The safety criteria will be 
evaluated in this population. 
A listing of patients excluded from the PP population will be provided with the reasons for exclusion. 
 
6.2 Definition of analysis subgroups 
Not applicable 
 
7 Statistical methods 
 
Statistical analyses will be performed by the CRGA. 
 
7.1 General information on statistical analysis methods 
 


 
Statistical Analysis Plan - Final Analysis - FFCD 1104 -EVACEL - Version 1.4 : 19/06/18 
Page 14 on 20 
7.1.1 
Software 
Statistical analyses will be performed with SAS software version 9.4 or later. Some graphs can be made with 
R software version 2.11 or later. 
7.1.2 
Adjustments to SSP 
Adjustments may be made to this analysis plan in case of amendments to the protocol, or if phenomena not 
initially foreseen require statistical adaptations. In all cases, these modifications must be made before the 
database is frozen. 
 
7.1.3 
Agreements concerning dates and durations 
Time since inclusion will be defined as the time since the day of inclusion, with the day of inclusion 
considered as day 1. 
The time since the start of treatment will be defined as the time since the day of the first treatment, the day 
of the first treatment being considered as day 1.  
Therefore, the durations will be calculated according to the following rule, for example for the duration 
between death and inclusion: day of death - day of inclusion + 1. 
The day before the day of inclusion (resp. the day before the day of treatment) will be considered as day -1 
(day 0 does not exist). 
The last date of news will be by default the date of the last examination/monitoring performed. 
The following conversion rules will be used to convert the number of days into months or years: 1 month = 
30.4375 days; 1 year = 365.25 days. 
 
7.1.4 
Outlier Conventions 
Outliers will be subject to a confirmation request to the investigating center. In case of confirmation, their 
value will not be modified and will be taken into account as it is during the analysis. 
 
7.1.5 
Missing Data Conventions 
Except in the cases specified, missing data will not be replaced. 
In case of partially missing data concerning dates, the following rule will be applied: when the day is missing, 
the day will be considered as the 15th of the month. 
 
7.1.6 
Definition of the baseline 
Baseline measurements will be the last measurements taken at inclusion. In case of missing data, the last 
measurement performed before the first administration of the treatment will be used. 
 
7.1.7 
Statistics 
Quantitative variables will be described using the number, median, mean, standard deviation of the mean, 
minimum, maximum, and interquartile range (Q1-Q3). Quantitative variables may be categorized using 
their median or a cut-off known from the medical literature. 
 


 
Statistical Analysis Plan - Final Analysis - FFCD 1104 -EVACEL - Version 1.4 : 19/06/18 
Page 15 on 20 
Categorical variables will be described using percentages, and if necessary their two-sided 95% 
confidence intervals (calculated using the exact method). 
Missing values will not be included in the calculation of frequencies and percentages. 
 
The confidence intervals provided will be two-sided 95% confidence intervals, except for the primary 
criterion where a one-sided 95% confidence interval will be given. 
 
Survival data will be estimated and plotted using the Kaplan-Meier method (Kaplan and Meier, 1958).  
This will be described by the median and rates calculated at different times. Two-sided 95% confidence 
intervals will be provided. Confidence intervals for the rates will be constructed from the Greenwood 
variance calculated using the log-log transformation. 
The median follow-up time will be calculated using the reverse Kaplan-Meier method (Shemper, 1996). 
 
For uni and multivariate analyses, hazard ratios will be estimated using a Cox model (Cox, 1984). The 
proportionality of the rates will be tested using the graphical representation and the test based on 
Schöenfeld residuals (Grambsch, 1994); the linearity of the effect of the continuous variables on the risk 
will be assessed from the graphical representation of the martingale residuals. Confidence intervals for the 
coefficient estimates of the Cox models will be calculated using the Wald method.
