Introduction
3.1
Background
Diabetic retinopathy is a major cause of visual impairment.  Diabetic macular edema (DME) 
is a manifestation of DR and is the most frequent cause of blindness in young and mid-aged 
adults (Moss et al. 1998).  It is estimated that 4.8% of the global population has diabetic 
retinopathy, while 3% to 4.1% of Europeans are affected (Prokofyeva & Zrenner 2012).
Vascular endothelial growth factor (VEGF), a protein growth factor that both stimulates 
angiogenesis and increases vascular permeability, plays a key role in the pathophysiology of 
DME (Bhagat et al. 2009).  Hypoxia and other metabolic factors trigger VEGF release.  
VEGF induces vascular leakage and neovascularization.  While neovascularization is the most 
severe manifestation of DR, vascular leakage leading to macular edema is an important cause 
of reduced visual acuity (VA). 
VEGF Trap-Eye is a recombinantly produced fusion protein consisting of the Fc domain of 
human IgG1 fused to portions of the human VEGF receptor extracellular domains.  It has a 
high binding affinity for VEGF and can neutralize VEGF mediated biological activity.  
Therefore, VEGF Trap-Eye may effectively block a key pathway in DME pathophysiology.
Further details can be found in the latest available version of the investigator's brochure, 
which contains comprehensive information on the study drug.
The detrimental impact on quality of life (QoL) from vision loss compounds any loss in QoL 
due to diabetes or its complications and comorbidities.  This combined with the threat of 
further declines in visual function, or uncertain prospect of an uncomfortable treatment, may 
affect patients’ psychological state or lead to social isolation (Droege et al. 2014; Lloyd et al. 
2013)
Among the several condition-specific measures or instruments which are designed to capture 
the specific impact of vision loss on health-related quality of life (HRQoL) is the National 
Eye Institute Visual Function Questionnaire (NEI VFQ-25).  This is probably the most widely 
used and researched instrument of this type, measuring vision-related quality of life (VRQoL)
(Lloyd 2013, Mangione 2001).  It was used in the pivotal trials for DME (VIVID DME and 
VISTA DME).  The generic HRQoL measure, EQ-5D, also included in VIVID and VISTA, is 
now known to be unable to distinguish between different severity levels in patients with DR
(Tosh et al. 2012).
3.2
Rationale of the study
Little is known about (i) QoL outcomes in DME patients treated with aflibercept per the 
European SmPC, or (ii) the relative influence of the visual acuity of better- and worse-seeing 
eyes on QoL in such patients.
Clinicians and others can use the results of studies in which QoL has been assessed to 
understand better how diabetes and its treatment affects outcomes that are important to 

Integrated Clinical Study Protocol

patients, and understand motivations for continuing treatment (Speight et al. 2009).  
Therefore, it is important to measure patients’ ability to function and complete their usual 
activities (vision-related quality of life, VRQoL), as this may represent an important element 
of QoL in patients with DME that may be influenced by treatment (Hirneiss 2014).
Vision in the better-seeing eye has been thought to have a stronger influence on VRQoL than 
that in the worse-seeing eye, although the relative strength of influence has recently come into 
question (Hirneiss 2014).  For example, in the RESTORE trial, 12-month gains in the near 
and distance subscales of NEI VFQ 25, and the composite score, were generally higher in 
anti-VEGF-treated patients who received their treatment in their better-seeing eye rather than 
in their worse-seeing eye (Mitchell et al. 2013).  
As per study protocol, most of the VRQoL data in the Phase-3 program (VIVID DME and 
VISTA DME) was obtained from patients whose (treated) study eye was their worse-seeing 
eye.  For subjects who met study eligibility criteria in both eyes, the study protocols specified 
that the eye with the worse visual acuity was to be selected as the study eye.  Because of this, 
VRQoL results may have become confounded and dominated by the vision of the better-
seeing fellow eye, which was permitted to be treated with anti-VEGFs as part of any standard 
care administered.
The minimally difference which can be assessed as being clinically relevant is a 4 to 6 points 
according to Hirneiss (2014). The clinical relevance of VRQoL changes on this instrument in 
DME is not well known, and may differ from 4-6 points above, largely evidenced from 
nAMD studies. This study provides an opportunity to establish what points change in this 
well-used instrument may be clinically relevant for DME (e.g. like Suner et al. [2009] did for 
nAMD).
This study aims to systematically and prospectively collect data on VRQoL outcomes in 
patients with DME treated with aflibercept per the European SmPC.  It also permits 
exploratory analyses of the relative influence of the visual acuity of better- and worse-seeing 
eyes on VRQoL in such patients.
A further rationale for this study is an explicit request by EMA to conduct a long-term post-
approval efficacy study (PAES) with aflibercept in DME; for that study, a sufficiently large 
population of patients IVT pre-treated according to the aflibercept EU label is required.  
Subjects completing the present protocol may subsequently be enrolled into the sponsor’s 
DME PAES.
3.3
Benefit-risk assessment
Throughout the entire study, all subjects enrolled will receive active treatment approved for 
DME with close medical supervision according to established local standard of care in clinical 
practice.
Taken together, participation in this study is not expected to bear an incremental risk for the 
enrolled subjects.

Open-label setting: This is a single arm study without masking requirements.  Treatment in 
this study is according to EU label for DME. 
The length of the observation period (1 year) is based on the primary-endpoint results of the 
pivotal DME studies (VISTA DME, VIVID DME), where most of the benefits after start of 
treatment with aflibercept occurred during the initial year of treatment.
End of study
The end of the study as a whole will be reached as soon as the last visit of the last subject has 
been reached in all centers in all participating countries (EU and non-EU).

Withdrawal of subjects from study
6.3.1
Withdrawal - amended
Withdrawal criteria
Subjects must be withdrawn from the study if any of the following occurs:
At their own request or at the request of their legally acceptable representative.  At any 
time during the study and without giving reasons, a subject may decline to participate 
further.  The subject will not suffer any disadvantage as a result.
Lost-to-follow-up.  A subject will be considered lost-to-follow-up if he/she misses two 
consecutive pre-planned study visits without a major reason agreed upon by the 
sponsor.  All attempts to contact the subject must be documented in the subject’s source 
documents.  
Relevant laboratory abnormality or SAEs, if sponsor or investigator sees this as medical 
reason to warrant withdrawal.
A female subject becomes pregnant.
At the discretion of the treating physician.  The development of conditions which would 
have prevented a subject’s entry into the study according to the selection criteria is no 
reason per se for withdrawal.  However, the withdrawal in such cases remains at the 
discretion of the treating physician.
Determination by the investigator that the current aflibercept therapy needs to be 
replaced by another treatment for DME.
AE (ocular or non-ocular) that, from the subject’s or the investigator’s view, is serious 
enough to require withdrawal from the study.  The investigator must notify the sponsor 
immediately if a subject is withdrawn because of an AE.

Integrated Clinical Study Protocol
No.  BAY 86-5321 /17850   
07 September 2015  
Version 2.0  
Page:  18 of 94
Decision by the investigator or sponsor that termination is in the subject’s best medical 
interest or administrative decision for a reason other than an AE.
Decision by the sponsor to halt the entire study. 
Subjects may be withdrawn from the study if any of the following occurs:
If, in the investigator's opinion, continuation of the study would be harmful to the 
subject's well-being
At the specific request of the sponsor and in liaison with the investigator (e.g. obvious 
non-compliance, safety concerns).
Depending on the time point of withdrawal, a withdrawn subject is referred to as either 
“screening failure” or “dropout” as specified below:
Screening failure
A subject who, for any reason (e.g. failure to satisfy the selection criteria), terminates the 
study before the time point used for the definition of “dropout” (see below) is regarded a 
“screening failure”. 
Re-screening of screening failures may be acceptable under the following conditions:
The subject had successfully passed the screening procedures, but could not start 
subsequent treatment on schedule.
The inclusion / exclusion criteria preventing the subject’s initial attempt to participate 
have been changed (via protocol amendment).
The reason for the screening failure was subsequently resolved (e.g. decrease of 
elevated IOP, controlled arterial hypertension) within 30 days.4
Under any of the above exceptions, a subject may be re-screened once only.  To be eligible, 
re-screened subjects must meet all selection criteria at the re-screening visit.
The investigator must ensure that the repeated screening procedures do not expose the subject 
to an unjustifiable health risk.  Also, for re-screening, the subject must re-sign the informed 
consent form, even if it was not changed after the subject’s previous screening.
Dropout
A subject who discontinues study participation prematurely for any reason is defined as a 
“dropout” if the subject has already received at least one dose of study medication.

General procedures
In all cases, the reason for withdrawal must be recorded in the CRF and in the subject's 
medical records. 
The subject may object to the generation and processing of post-withdrawal data as specified 
in Section 13.4.
Any subject removed from the trial will remain under medical supervision as medically 
needed.
Details for the premature termination of the study as a whole (or components thereof) are 
provided in Section 12.

7.4
Dosage and administration - amended
The study drug will be supplied in kits that include the following:

Sterile study drug in sealed glass vials (2 mL) with a withdrawable volume of 0.1 mL
(see Table 7–1 for details on the composition of the study drug)

Filter needle (18 gauge)
Other ancillary components required for the administration of aflibercept (e.g. 30-gauge 
injection needle; 1-mL syringe) will be supplied by the study site.  
Preparation of the solution
Based on present stability information, the preparation of the solution should be scheduled to 
ensure that the subsequent injection is completed within 2 hours of the start of the preparation.
When aflibercept vials are removed from the refrigerator, the solution should be visually 
inspected and it should have no evidence of turbidity.  If particulates, cloudiness, or 
discoloration are visible, the vial must not be used.  
After opening the vial, all preparation steps have to take place under aseptic conditions.
The study drug will be withdrawn using aseptic technique through the filter needle attached to 
the syringe.  The filter needle will be discarded after withdrawal of the vial contents and must 
not be used for IVT injection.  The filter needle should be replaced by the sterile 30-gauge 
needle for the IVT injection.  
Dosage
For the 2-mg dose of aflibercept, the volume of injection is 50 L (0.05 mL).  Thus, the 
syringe contents should be expelled until the plunger is aligned with the line that marks 
0.05 mL on the syringe.
Administration
Aflibercept is administered via IVT injection.  The injection must be completed within 
2 hours of the start of dose preparation.
Posology
All subjects enrolled in this single-arm study will be receive aflibercept according to EU label 
for the first year in an open-label fashion, i.e. 5 monthly intravitreal injections followed by 
intravitreal injections every 8 weeks.

Consideration of special warnings from EU label 6
The investigator should consider the special warnings as described in the EU label for 
aflibercept. However, ultimately the investigator should include in his/her treatment decision 
all subject related information and data available and based on this decide what would be best 
for the subject.
The approved EU label for aflibercept includes the following special warnings:
Treatment should be withheld in patients with rhegmatogenous retinal detachment or 
stage 3 or 4 macular holes.  In the event of a retinal break, the dose should be withheld 
and treatment should not be resumed until the break is adequately repaired. 
The dose should be withheld and treatment should not be resumed earlier than the next 
scheduled treatment in the event of:

a decrease in best-corrected visual acuity (BCVA) of ≥30 letters compared 
with the last assessment of visual acuity; 

a subretinal haemorrhage involving the centre of the fovea, or, if the size of the 
haemorrhage is ≥50%, of the total lesion area 
The dose should be withheld within the previous or next 28 days in the event of a 
performed or planned intraocular surgery 
7.5
Masking
Not applicable - this is an open-label study.  
7.6
Drug logistics and accountability
Packaging
Aflibercept will be supplied by the sponsor in treatment kits described in Section 7.4. 
Supply
The treatment kits will be shipped to the investigator at regular intervals or as needed during 
the study.  Study drug will be shipped to the site using appropriate methods to maintain 
transport conditions within those recommended by its stability profile.  The investigator, or an 
approved representative (e.g. pharmacist), will ensure that all received study drugs are stored 
in a secured area on site, under recommended storage conditions and in accordance with 
applicable regulatory requirements.

Storage
All study drugs will be stored at the investigational site in accordance with GCP and GMP 
requirements and the instructions given by the clinical supplies department of the sponsor (or 
its affiliate/CRO), and will be inaccessible to unauthorized personnel.  Special storage 
conditions and a complete record of batch numbers and expiry dates can be found in the 
sponsor’s study file; the site-relevant elements of this information will be available in the 
investigator site file.  
Accountability
On the day of receipt, the responsible site personnel will confirm receipt of study drug via 
IxRS.  The personnel will use the study drug only within the framework of this clinical study 
and in accordance with this protocol.  Receipt, distribution, return and destruction (if any) of 
the study drug must be properly documented according to the sponsor’s agreed and specified 
procedures.
Written instructions on medication destruction will be made available to affected parties as 
applicable.
If performing drug accountability implies a potential risk of contamination, a safety process/ 
guidance for handling returned drug will be provided.
7.7
Treatment compliance
As all study drugs will be administered in a medical facility by authorized site personnel, 
compliance with the dosing protocol will be monitored by review of clinic records.

Non-study therapy
8.1
Prior and concomitant therapy
Any relevant previous and concomitant treatments, including surgeries and laser treatments, 
will be recorded in the source documentation and then entered into the “Previous and 
Concomitant Medications” eCRF screen using the brand name.   
All recorded previous and concomitant medications will be coded using an internationally 
recognized and accepted coding dictionary.  
8.1.1
Prior therapy
In particular, any potential previous treatments for DME will be recorded, including treatment 
with anti VEGF medication, steroids or laser.
Prior treatments that exclude subjects from participation in this study are given in Section 6.2.
8.1.2
Concomitant therapy
Any medications considered necessary for the subject’s welfare, and that are not expected to 
interfere with the evaluation of the study drug, may be given at the discretion of the 
investigator, with the exceptions noted below.
8.1.2.1
Study-eye treatment
Subjects may not receive any standard or investigational pharmacological agents for treatment 
of their DME in the study eye other than aflibercept as specified in this protocol until they 
have completed the assessments scheduled for the Completion / Early Termination visit.  This 
includes medications administered locally (e.g. IVT, by juxtascleral or periorbital routes), as 
well as those administered systemically with the intent of treating either eye.  Ocular laser 
photocoagulation or surgery may be performed if necessary by the investigator.
8.1.2.2
Fellow-eye treatment
If the fellow eye shall be treated pharmacologically, the most applicable treatment option that 
is approved by the governing health authorities may be selected at the investigator’s discretion 
in the subject’s best interest.  
If the fellow (non-study) eye has DME, the fellow eye may receive any locally approved non-
systemic treatment (note that fellow-eye aflibercept treatment may be used under this 
protocol).

Page:  25 of 94
Even if treated with aflibercept, the fellow eye will not be considered an additional study eye.  
If no drug therapy has been approved for the indication or if the approved therapy is not 
appropriate due to medical reasons, a non-approved pharmacological approach may be 
selected, if it can be considered as standard of care. 
8.2
Post-study therapy
After the end of this study, subjects will not be restricted with regard to pursuing available 
treatments for DME.
After completion of this study, subjects may subsequently be enrolled into the sponsor’s post-
approval efficacy study further investigating the efficacy of aflibercept in DME patients.

Adverse events
9.6.1.1
Definitions
Definition of adverse event (AE)
In a clinical study, an AE is any untoward medical occurrence (i.e. any unfavorable and 
unintended sign [including abnormal laboratory findings], symptom or disease) in a 
patient or clinical investigation subject after providing written informed consent for 
participation in the study.  Therefore, an AE may or may not be temporally or causally 
associated with the use of a medicinal (investigational) product.
A surgical procedure that was planned prior to the start of the study by any physician treating 
the subject should not be recorded as an AE (however, the condition for which the surgery is 
required may be an AE).
Medical history versus adverse event 
In the following differentiation between medical history and AEs, the term “condition” may 
include abnormal physical examination findings, symptoms, diseases, laboratory findings, 
ECG findings, or other abnormal findings.
Conditions that started before signing of informed consent and for which no 
symptoms or treatment are present until signing of informed consent are recorded as 
medical history (e.g. seasonal allergy without acute complaints).
Conditions that started before signing of informed consent and for which symptoms 
or treatment are present after signing of informed consent, at unchanged intensity, 
are recorded as medical history (e.g. allergic pollinosis).
Conditions that started or deteriorated after signing of informed consent will be 
documented as adverse events.  This includes intercurrent illnesses.

Definition of serious adverse event (SAE)
An SAE is classified as any untoward medical occurrence that, at any dose, meets any of the 
following criteria (a – f):
a.
Results in death
b. Is life-threatening
The term ‘life-threatening’ in the definition refers to an event in which the subject 
was at risk of death at the time of the event, it does not refer to an event which 
hypothetically might have caused death if it were more severe.
c.
Requires inpatient hospitalization or prolongation of existing hospitalization
A hospitalization or prolongation of hospitalization will not be regarded as an SAE if 
at least one of the following exceptions is met:
The admission results in a hospital stay of less than 12 hours
The admission is pre-planned 
(e.g. elective or scheduled surgery arranged prior to the start of the study;
admission is part of the study procedures as described in Section 9.2)
The admission is not associated with an AE 
(e.g. social hospitalization for purposes of respite care).
However, it should be noted that invasive treatment during any hospitalization may 
fulfill the criterion of ‘medically important’ and as such may be reportable as an SAE 
dependent on clinical judgment.  In addition, where local regulatory authorities 
specifically require a more stringent definition, the local regulation takes precedence.
d. Results in persistent or significant disability / incapacity
Disability means a substantial disruption of a person’s ability to conduct normal life’s 
functions.
e.
Is a congenital anomaly / birth defect
f.
Is another serious or important medical event as judged by the investigator

9.6.1.2
Classifications for adverse event assessment
All AEs will be assessed and documented by the investigator according to the categories 
detailed below.  
9.6.1.2.1
Seriousness
For each AE, the seriousness must be determined according to the criteria given in 
Section 9.6.1.1.
9.6.1.2.2
Intensity
The intensity of an AE is classified according to the following categories:
Mild
Moderate
Severe
9.6.1.2.3
Causal relationship 
In this study, adverse events will be assessed as causally related/not related to (i) the study 
drug, (ii) IVT injection, and (iii) other protocol-specified procedures.  The assessment is a 
decision to be made by the investigator, who is a qualified physician, based on all information 
available at the time of the completion of the CRF.
The causal relationship will be recorded using the following terms:
Causal relationship to study drug
The assessment is based on the question whether there was a “reasonable causal relationship” 
to the study treatment in question.
Possible answers are “yes” or “no”
An assessment of “no” would include:
1.
The existence of a highly likely alternative explanation, e.g. mechanical bleeding at 
surgical site.
or
2.
Non-plausibility, e.g. the subject is struck by an automobile when there is no 
indication that the drug caused disorientation that may have caused the event; cancer 
developing a few days after the first drug administration.
An assessment of “yes” indicates that that the AE is reasonably associated with the use of the 
study treatment.

07 September 2015  
Version 2.0  
Page:  38 of 94
Important factors to be considered in assessing the relationship of the AE to study treatment 
include:
The temporal sequence from drug administration:  The event should occur after the drug 
is given.  The length of time from drug exposure to event should be evaluated in the 
clinical context of the event.
Recovery on drug discontinuation (de-challenge), recurrence on drug re-introduction 
(re-challenge):  Subject’s response after de-challenge or re-challenge should be 
considered in view of the usual clinical course of the event in question.
Underlying, concomitant, intercurrent diseases: 
Each event should be evaluated in the context of the natural history and course of the 
disease being treated and any other disease the subject may have.
Concomitant medication or treatment: 
The other drugs the subject is taking or the treatment the subject receives should be
examined to determine whether any of them might have caused the event in question.
Known response pattern for this class of drug: Clinical/preclinical
Exposure to physical and/or mental stresses: The exposure to stress might induce adverse 
changes in the recipient and provide a logical and better explanation for the event
The pharmacology and pharmacokinetics of the study treatment: 
The pharmacokinetic properties (absorption, distribution, metabolism and excretion) of 
the study treatment, coupled with the individual subject’s pharmacodynamics should be 
considered.
The assessment is not possible
Causal relationship to the injection procedure
The assessment of a possible causal relationship between the AE and the injection procedure 
is based on the question whether there was a “reasonable causal relationship” to the injection 
procedure.
Possible answers are “yes” or “no”
-
Not related:  AEs that were clearly and incontrovertibly due to causes other than the 
IVT injection procedure (e.g. disease, environment), or were felt with a reasonable 
degree of certainty to be unrelated to the IVT injection procedure.
-
Related: AEs for which a connection with the IVT injection procedure could not be 
ruled out with certainty, or which were felt with a reasonable degree of certainty to be 
related to the IVT injection procedure, or which were incontrovertibly related to the IVT 
injection procedure.
A possible example of an injection-related AE would be eye pain at the site of the injection.

Page:  39 of 94
Causal relationship to other protocol-required procedure(s)
The assessment of a possible causal relationship between the AE and protocol-required 
procedure(s) is based on the question whether there was a “reasonable causal relationship” to 
protocol-required procedure(s).
Possible answers are “yes” or “no”
-
Not related:  AEs that were clearly and incontrovertibly due to causes other than a 
protocol-specified procedure (e.g. disease, environment), or were felt with a reasonable 
degree of certainty to be unrelated to a protocol-specified procedure other than the IVT 
injection.
-
Related:  AEs for which a connection to a protocol-specified procedure other than the 
IVT injection could not be ruled out with certainty, or which were felt with a reasonable 
degree of certainty to be related to a protocol-specified procedure other than the IVT 
injection, or which were incontrovertibly related to a protocol-specified procedure other 
than the IVT injection.
A possible example of a procedure-related AE would be bruising at the site of a blood draw.
9.6.1.2.4
Action taken with study treatment 
Any action on study treatment to resolve the AE is to be documented using the categories 
listed below.
Drug withdrawn
Drug interrupted

9.6.1.3
Assessments and documentation of adverse events
Attention is to be paid to the occurrence of adverse events at all stages of the examination.  
Thus, the subject should be closely observed by the investigator.  In case of ongoing drug- or 
injection-related adverse events and medically relevant adverse events at the end of the study, 
the investigator should monitor the subject and document the outcome on the subject’s source 
documents.
The investigator has to record on the respective CRF pages all adverse events (irrespective of 
any causal relationship or seriousness) occurring in the period between the signing of the 
informed consent and the end of the 4-weeks period after the last aflibercept injection.
After the end of this period, there is no requirement to actively collect AEs including deaths.  
For any drug-related AE occurring after the end of this period, the standard procedures that 
are in place for spontaneous reporting will be followed.
The type of information that should be assessed and recorded by the investigator for each AE 
is listed in Section 9.6.1.2. 
“Death” should not be recorded as an AE on the AE page.  Instead, death is the outcome 
“fatal” of underlying AE(s).
For all serious adverse events (SAEs) the sponsor has to carry out a separate assessment for 
expectedness, seriousness and causal relationship to study drug.
The means of obtaining information on an AE (e.g. observed, volunteered, or elicited) is to be 
documented in detail on the eCRF.  The following information is required to be recorded:

The specification of the adverse event

The date of onset 

The maximum intensity 

Any study drug action and other action taken by the investigator to resolve the adverse 
events 

Integrated Clinical Study Protocol


Any specific drug or non-drug treatment of the adverse event

The drug relationship of the adverse event to aflibercept, the IVT injection, or other 
protocol-specified procedures 

The outcome of the adverse event (for definitions, see above).

If recovered/resolved or fatal – the date ended.
ATE analysis
Potential arterial thrombotic events (ATEs) will be evaluated by an adjudication committee 
according to criteria formerly applied and published by the Anti-Platelet Trialists’ 
Collaboration (APTC) (Antithrombotic Trialists' Collaboration 2002).  The definition of 
ATEs as well as further details are described in the adjudication committee charter.
9.6.1.4
Reporting of serious adverse events
The definition of serious adverse events (SAEs) is given in Section 9.6.1.1. Each SAE must 
be followed up until resolution or stabilization by submission of updated reports to the 
designated recipient.
Investigator’s notification of the sponsor
All investigators will be thoroughly instructed and trained on all relevant aspects of the 
investigator’s reporting obligations for SAEs.  This information, including all relevant contact 
details, is summarized in the investigator site file.  This information will be updated as 
needed.
The investigator must report immediately (within 24 hours of the investigator’s awareness) all 
SAEs occurring during the observation period defined in Section 9.6.1.3 to the recipient 
detailed in the instructions for SAE reporting included in the Investigator File.  For this, an 
AE page in the CRF as well as the complementary pages provided in the Investigator File 
must be completed for each SAE.  Information not available at the time of the initial report 
must be documented on a follow-up SAE form.  The sponsor or designee may request 
substantiating data such as relevant hospital or medical records, diagnostic test reports, and 
death or autopsy reports.
SAEs occurring after the protocol-defined observation period will be processed by the 
sponsor according to all applicable regulations.
Notification of the IECs / IRBs
Notification of the IECs / IRBs about all relevant events (e.g. SAEs, suspected, unexpected, 
serious adverse reactions [SUSARs]) will be performed by the sponsor and/or by the 
investigator according to all applicable regulations.

Notification of the authorities
The processing and reporting of all relevant events (e.g. SAEs, SUSARs) to the authorities 
will be done by the sponsor according to all applicable regulations.
Sponsor’s notification of the investigational site
The sponsor will inform all investigational sites about reported relevant events (e.g. SUSARs) 
according to all applicable regulations.
9.6.1.5
Expected adverse events - amended
Information on AEs with an onset after the first application of the test drug is provided in the 
local label. 19
The expectedness of AEs will be determined by the sponsor according to the applicable 
reference document and according to all local regulations.
9.6.2
Pregnancies - amended
The investigator must report to the sponsor any pregnancy occurring in a female study subject 
during her participation in this study.  The outcome of the pregnancy should be followed up 
carefully, and any outcome of the mother and the child at delivery should be reported.
The child’s health should be followed up until three months after birth.
For a pregnancy in the partner of a male study subject, all efforts will be made to obtain 
similar information on course and outcome, subject to the partner’s consent.
For all reports, the forms provided are to be used.  The investigator should submit them within 
the same timelines as an SAE. 
Results from animal studies with high systemic exposure indicate that aflibercept can impair 
male and female fertility. Such effects are not expected after ocular administration with very 
low systemic exposure. 20

Statistical and analytical plans 
10.3.2.1
Demography and baseline characteristics - amended
Demographic variables and baseline characteristics will be summarized for both 23 analysis 
sets, depending on the type of data as described in Section 10.1.  Medical history will be 
coded by MedDRA codes and prior and concomitant medications by ATC codes (WHO DD). 
The number of injections will be tabulated.  
10.3.2.2
Efficacy analyses
All efficacy variables will be analyzed on the FAS.
Primary efficacy variable
The analyses of the primary efficacy variable will be descriptively.  95% confidence intervals 
will be provided based on the t-distribution assuming that the changes from baseline are 
normally distributed. 
To be comparable with publications of other studies in this indication, missing values will be 
imputed with the last observed post-baseline value collected before the missing value 
(LOCF). 
Frequencies of subjects worsening or improving (separately for not achieving, achieving or 
exceeding the clinically meaningful difference specified in Section 10.4) will be computed for 
each time point.
With regard to the classification of clinical meaningfulness of QoL at Week 52, mean change 
in BCVA will be calculated for each of the two categories.  The difference in mean change in 
BCVA between the two categories of clinically meaningfulness of QoL will be evaluated, 
together with t-distribution-based 95% confidence intervals.
As sensitivity analysis a multiple imputation (MI) analysis will be provided.  The imputations 
will be based on the baseline value as well as all observed changes from baseline.
Furthermore, a repeated-measurements-model analysis will be conducted including the visit 
as fixed factor and the baseline value and the baseline*visit interaction as covariate.
In addition, the effect of the choice of the study eye on the quality of life (better seeing eye vs. 
worse seeing eye) will be investigated.
Further exploratory analyses will be conducted to investigate the intra-individual variability in 
the score over time and the correlation between the BCVA value in both eyes and the score.

Secondary efficacy variables
The secondary efficacy variables will be analyzed descriptively in analogy to the primary 
efficacy variables.
Exploratory efficacy variables
All exploratory variables will be analyzed descriptively.
10.3.2.3
Safety analyses - amended
All safety variables will be summarized descriptively on the SAF.
Adverse events
Treatment-emergent AEs will be presented by MedDRA preferred term within primary 
system organ class (SOC). 24  Intensity and causal relationship to the investigational product 
will be analyzed descriptively.  Non-ocular, ocular AEs in the study eye, and non-ocular AEs 
in the fellow eye will be displayed separately.
Potential arterial thrombotic events (ATEs) as described in Section 9.6.1.3 will be presented 
separately.
Other safety variables
Other safety variables (e.g. IOP measurements, vital signs and laboratory tests) will be 
analyzed descriptively including changes from baseline.  The descriptive analysis of 
laboratory data will include a listing of laboratory data that fall outside of normal range, and 
the calculation of incidence rates for treatment emergent laboratory abnormalities by 
treatment group.
10.4
Determination of sample size
A total of approximately 450 to 520 subjects is planned to be enrolled.  This takes the
sponsor’s planned subsequent post-approval efficacy study into consideration.
In a previously conducted study with aflibercept in DME, the standard deviation observed for
the change from baseline to Week 52 in the NEI VFQ-25 total score was 11.
Assuming a similar variability (SD = 11), with a sample size of 450 subjects (520 subjects), 
the difference between the mean and the limits of the 95% confidence intervals will not 
exceed 1.1 (1.0) with a probability of 90%.

As the minimal clinically important difference (MCID) has been reported to be in the range of 
4 to 6 (Hirneiss 2014), for the context of this study, it was decided to use the value of 5 as 
MCID.  The change in QoL will be classified according to the two categories 

Change ≥MCID

Change < MCID (this includes no change or deteriorations).  
In both categories, the mean change from baseline in BCVA will be evaluated, and a 95% 
confidence interval for the difference between both categories will be calculated.  Taken the 
sample size range specified above and assumptions25 for the distribution of subjects on the 
two MCID categories, the length of this respective confidence interval will not exceed 1.8 to 
1.9 letters with a probability of 90% (with SD = 10 for change in BCVA based on previously 
conducted studies with aflibercept in DME). 
This precision is considered to be sufficient to assess the relevance of change in QoL over 
time, and in relation to BCVA measurements.
Sample size calculated with PASS (Power Analysis & Sample Size) v. 11 (Confidence 
Intervals for One Mean with Tolerance Probability and Confidence Intervals for the 
Difference Between Two Means with Tolerance Probability).

Data handling and quality assurance
11.1
Data recording
The data collection tool for this study will be a validated electronic data capture system called 
RAVE.  Subject data necessary for analysis and reporting will be entered/transmitted into a 
validated database or data system (TOSCA; SAS). 
Data required according to this protocol will be recorded by investigational site personnel via 
data entry into the internet based EDC software system RAVE, which Bayer/CRO has 
licensed from Medidata Solutions Worldwide.  RAVE has been validated by Medidata 
Solutions Worldwide and Bayer/CRO for use in its clinical studies.  RAVE allows for the 
application of software logic to set-up data entry screens and data checks to ensure the 
completeness and accuracy of the data entered by the site personnel.  Bayer/CRO extensively 
                                                
25 Based on former aflibercept in DME studies, and considering the slightly different population in this study, a proportion 
between 50:50 and 70:30 is assumed.

applies the logic to ensure data are complete and reflect the clinical data requirements of the 
study.  Data queries resulting from the application of the software logic are resolved by the 
site personnel.  The data are stored at a secure host facility maintained by Medidata Solutions 
Worldwide and transferred on a periodic basis to the sponsor's internal computer system via a 
secure Virtual Private Network.
All access to the RAVE system is through a password-protected security system that is part of 
the RAVE software.  All internal Bayer and external investigator site personnel seeking 
access must go through a thorough RAVE training process before they are granted access to 
RAVE for use in Bayer's clinical studies.  Training records are maintained.
All personnel with access to the RAVE system are supported by a Service Desk staffed with 
trained personnel to answer questions and ensure access is maintained such that data entry can 
proceed in a timely manner.
The RAVE System contains a system-generated audit trail that captures any changes made to 
a data field, including who made the change, why the change was made and the date and time 
it was made.  This information is available both at the investigator’s site and at Bayer.  Data 
entries made in the RAVE EDC screens are supported by source documents maintained for all 
subjects enrolled in this study.
Source documentation
It is the expectation of the sponsor that key data entered into the CRF has source 
documentation available at the site. 
The site must implement processes to ensure availability of all required source 
documentation.  A source document checklist (not part of this protocol) will be used at the 
site to identify the source data for key data points collected and the monitor will work with the 
site to complete this.
Data recorded from screening failures
Data of 'only screened subjects' will be recorded at least as source data.  At minimum, the 
following data should be recorded in the CRF:
Demographic information (subject number; year of birth / age; sex; if applicable 
race / ethnicity)
Date of informed consent
Reason for screen failure
Date of last visit.  
These data will be transferred to the respective database.

addition to the data specified above:
All information related to the SAE such as: 

Concomitant medication

Medical history

Other information needed for SAE complementary page
11.2
Monitoring
In accordance with applicable regulations, GCP, and sponsor’s/CRO’s procedures, monitors 
will contact the site prior to the start of the study to review with the site staff the protocol, 
study requirements, and their responsibilities to satisfy regulatory, ethical, and sponsor’s 
requirements.  When reviewing data collection procedures, the discussion will also include 
identification and documentation of source data items.
The sponsor/designee will monitor the site activity to verify that the:
Data are authentic, accurate and complete. 
Supporting data may be requested (example: blood glucose readings to support a 
diagnosis of diabetes). 
Safety and rights of subjects are being protected
Study is conducted in accordance with the currently approved protocol 
(including study treatment being used in accordance with the protocol)
Any other study agreements, GCP, and all applicable regulatory requirements are met.
The investigator and the head of the medical institution (where applicable) agrees to allow the 
monitor direct access to all relevant documents.
11.3
Data processing
Data will be collected as described in Section 11.1.  Clinical data management will be 
performed in accordance with applicable sponsor’s/CRO’s standards and data cleaning 
procedures.  This is applicable for data recorded on CRF as well as for data from other 
sources (e.g. IxRS, adjudication committees).
For data coding (e.g. AEs, medication, medical history, surgeries), internationally recognized 
and accepted dictionaries will be used.

Missing data 
All efforts will be made to minimize the amount of missing data.  Measures for this include 
investigators’ training and timely monitoring of CRF entries for completeness (see 
Section 11.2).
11.5
Audit and inspection
To ensure compliance with GCP and regulatory requirements, a member of the sponsor’s (or a 
designated CRO’s) quality assurance unit may arrange to conduct an audit to assess the 
performance of the study at the study site and of the study documents originating there.  The 
investigator/institution will be informed of the audit outcome.
In addition, inspections by regulatory health authority representatives and IEC(s)/IRB(s) are 
possible.  The investigator should notify the sponsor immediately of any such inspection.
The investigator/institution agrees to allow the auditor or inspector direct access to all relevant 
documents and allocate his/her time and the time of his/her staff to the auditor/inspector to 
discuss findings and any issues.  Audits and inspections may occur at any time during or after 
completion of the study.
11.6
Archiving
Essential documents shall be archived safely and securely in such a way that ensures that they 
are readily available upon authorities’ request.
Patient (hospital) files will be archived according to local regulations and in accordance with 
the maximum period of time permitted by the hospital, institution or private practice.  Where 
the archiving procedures do not meet the minimum timelines required by the sponsor, 
alternative arrangements must be made to ensure the availability of the source documents for 
the required period.
The investigator/institution notifies the sponsor if the archival arrangements change (e.g. 
relocation or transfer of ownership).
The investigator site file is not to be destroyed without the sponsor’s approval.
The contract with the investigator/institution will contain all regulations relevant for the study 
center.

Each subject will be informed about the following aspects of premature withdrawal:
Each subject has the right to withdraw from the study at any time without any 
disadvantage and without having to provide reasons for this decision. 
The subject’s consent covers early-termination examinations as specified in the visit 
description described in Section 9.2.4 to be conducted after withdrawal of consent. 
The subject’s data that have been collected until the time of withdrawal will be retained 
and statistically analyzed in accordance with the statistical analysis plan. 
Subject-specific data on the basis of material obtained before withdrawal may be 
generated after withdrawal (e.g. image reading, analysis of biological specimen such as 
blood, urine or tissues); these data would also be retained and statistically analyzed in 
accordance with the statistical analysis plan.  The subject has the right to object to the 
generation and processing of this post-withdrawal data.  Each subject / legal representative
or proxy consenter will have ample time and opportunity to ask questions. 26
Only if the subject / legal representative or proxy consenter voluntarily agrees to sign the 
informed consent form and has done so, may he/she enter the study.  Additionally, the 
investigator will personally sign and date the form.  The subject / legal representative or proxy 
consenter will receive a copy of the signed and dated form.
The signed informed consent statement is to remain in the investigator site file or, if locally 
required, in the patient’s note/file of the medical institution.
In the event that informed consent is obtained on the date that baseline study procedures are 
performed, the study record or subject´s clinical record must clearly show that informed 
consent was obtained prior to these procedures.
If the subject is unable to read the informed consent form due to vision impairment, a family 
member, other legal representative of the subject, study nurse, or study physician may read 
the document to the subject and may assist the subject in signing the form.  In this case, the 
name of that person should be documented. 27
If the subject is not capable of providing a signature, a verbal statement of consent can also be 
given in the presence of an impartial witness (independent of the sponsor and the 
investigator).  This is to be documented by a signature from the informing physician as well 
as by a signature from the witness.
The informed consent form and any other written information provided to subjects / legal 
representatives or proxy consenters will be revised whenever important new information becomes 
available that may be relevant to the subject’s consent, or there is an amendment to the protocol 
that necessitates a change to the content of the subject information and / or the written informed 
consent form.  The investigator will inform the subject / legal representative or proxy consenter of 
changes in a timely manner and will ask the subject to confirm his/her participation in the study 
by signing the revised informed consent form.  Any revised written informed consent form and 
written information must receive the IEC/IRB`s approval / favorable opinion in advance of use.

Women and men of reproductive potential must agree to use adequate contraception 
when sexually active.  This applies for the time period between signing of the informed 
consent form and 3 months after the last administration of study drug. 
The definition of adequate contraception will be based on the judgment of the 
investigator and on local requirements.
Acceptable methods of contraception include, but are not limited to: (i) condoms (male or 
female) with or without a spermicidal agent; (ii) diaphragm or cervical cap with 
spermicide; (iii) intra-uterine device; (iv) hormone-based contraception.
Subjects must agree to utilize two reliable and acceptable methods of contraception 
simultaneously. 
Postmenopausal women must be amenorrheic for at least 12 months in order not to be 
considered of child bearing potential.

Criteria for re-screening clarified as per Modification 4 (Section 15.1.1.4)
Old text:
Screening failure
A subject who, for any reason (e.g. failure to satisfy the selection criteria), terminates the 
study before the time point used for the definition of “dropout” (see below) is regarded a 
“screening failure”. 
Re-screening of screening failures may be acceptable under the following conditions:
The subject had successfully passed the screening procedures, but could not start 
subsequent treatment on schedule.
The inclusion / exclusion criteria preventing the subject’s initial attempt to participate 
have been changed (via protocol amendment).
The reason for the screening failure was subsequently resolved (e.g. decrease of elevated IOP, 
controlled arterial hypertension).

Section 7.4 Dosage and administration
Following paragraph added below ‘Posology’ per Modification 6 (Section 15.1.1.6).
Consideration of special warnings from EU label
The investigator should consider the special warnings as described in the EU label for 
aflibercept. However, ultimately the investigator should  include in his/her treatment decision 
all subject related information and data available and based on this decide what would be best 
for the subject.
The approved EU label for aflibercept includes the following special warnings:
Treatment should be withheld in patients with rhegmatogenous retinal detachment or 
stage 3 or 4 macular holes.  In the event of a retinal break, the dose should be withheld 
and treatment should not be resumed until the break is adequately repaired. 
The dose should be withheld and treatment should not be resumed earlier than the next 
scheduled treatment in the event of:

a decrease in best-corrected visual acuity (BCVA) of ≥30 letters compared 
with the last assessment of visual acuity; 

a subretinal haemorrhage involving the centre of the fovea, or, if the size of the 
haemorrhage is ≥50%, of the total lesion area 
The dose should be withheld within the previous or next 28 days in the event of a 
performed or planned intraocular surgery

Each subject will be informed about the following aspects of premature withdrawal:
Each subject has the right to withdraw from the study at any time without any 
disadvantage and without having to provide reasons for this decision. 
The subject’s consent covers early-termination examinations as specified in the visit 
description described in Section 9.2.4 to be conducted after withdrawal of consent. 
The subject’s data that have been collected until the time of withdrawal will be retained 
and statistically analyzed in accordance with the statistical analysis plan. 
Subject-specific data on the basis of material obtained before withdrawal may be 
generated after withdrawal (e.g. image reading, analysis of biological specimen such as 
blood, urine or tissues); these data would also be retained and statistically analyzed in 
accordance with the statistical analysis plan.  The subject has the right to object to the 
generation and processing of this post-withdrawal data.  For this, he/she needs to sign a 
corresponding declaration of objection; alternatively, the subject’s oral objection may 
be documented in the subject’s source data.  Each subject / legal representative or 
proxy consenter will have ample time and opportunity to ask questions.
Only if the subject / legal representative or proxy consenter voluntarily agrees to sign the 
informed consent form and has done so, may he/she enter the study.  Additionally, the 
investigator will personally sign and date the form.  The subject / legal representative or proxy 
consenter will receive a copy of the signed and dated form.
The signed informed consent statement is to remain in the investigator site file or, if locally 
required, in the patient’s note/file of the medical institution.
In the event that informed consent is obtained on the date that baseline study procedures are 
performed, the study record or subject´s clinical record must clearly show that informed 
consent was obtained prior to these procedures.
