Brief summary:
To compare brolucizumab to aflibercept in Chinese patients with untreated active choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD)

Detailed description:
This was a randomized, double-masked, multicenter, parallel-group, active-controlled study. The study included 14 scheduled visits over 48 weeks. After confirmation of eligibility at baseline, participants were randomized in a 1:1 ratio to one of the 2 treatment arms:

* Brolucizumab 6 mg: 3 monthly intravitreal injections of brolucizumab 6 mg in the loading treatment period (q4w regimen) up to Week 8 followed by injections every 12 weeks (q12w regimen) or 8 weeks (q8w) up to Week 40 or Week 44, depending on disease activity status.
* Aflibercept 2 mg: 3 monthly intravitreal injections of aflibercept 2 mg in the loading treatment period (q4w regimen) up to Week 8 followed by injections every 8 weeks (q8w) up to Week 40. Disease activity assessments (DAAs) were conducted by the masked investigator for both treatment arms at Weeks 16, 20, 32 and 44 to determine the regimen of brolucizumab arm (i.e., q12w or q8w).

Arms:
arm 1: 3 monthly intravitreal injections of brolucizumab 6 mg in the loading treatment period (q4w regimen) up to Week 8 followed by injections every 12 weeks (q12w regimen) or 8 weeks (q8w) up to Week 40 or Week 44, depending on disease activity status. arm 2: 3 monthly intravitreal injections of aflibercept 2 mg in the loading treatment period (q4w regimen) up to Week 8 followed by injections every 8 weeks (q8w) up to Week 40.

Interventions: intervention 1: Brolucizumab 6mg intervention 2: Aflibercept 2 mg
Intervention descriptions: intervention 1: Intravitreal injection intervention 2: Intravitreal injection

center number, a unique identifier is created for each subject in the study.
Variable
A measured value or assessed response that is determined in specific assessments and 
used in data analysis to evaluate the drug being tested in the study
Withdrawal of 
study consent 
(WoC)
Withdrawal of consent from the study occurs when the participant explicitly requests to 
stop use of their data and biological samples (opposition to use data and biological 
samples) AND no longer wishes to receive study treatment, AND does not agree to 
further protocol required assessments. This request should be in writing (depending on 
local regulations) and recorded in the source documentation.

Amendment 4 (14-Jun-2022) 
Amendment rationale 
In the spirit of the bridging concept under ICH E5, and also based on the cumulative evidence 
on brolucizumab as of today (i.e., from the two successful global pivotal Phase III studies 
RTH258-C001 (HAWK) and RTH258-C002 (HARRIER)), the main purpose of this 
amendment is to adjust the alpha level from 0.05 to 0.1 to result in a sample size reduction 
from approximately 494 to 390 subjects.
In particular, data from the two global pivotal studies, RTH258-C001 (HAWK) and RTH258-
C002 (HARRIER), have demonstrated an overall favorable benefit-risk profile of 
brolucizumab in the treatment of subjects with nAMD. A total of 687 subjects were treated 
with brolucizumab 6 mg and completed Week 48 for the two pivotal studies. Both studies 
confirmed the hypotheses of non-inferiority of brolucizumab 6 mg to aflibercept 2 mg for the 
primary endpoint, BCVA change from Baseline to Week 48, with a non-inferiority margin of 
4 letters (1-sided significance level of 0.025). The least squares mean difference between the 
brolucizumab and aflibercept arms for RTH258-C001 (HAWK) and RTH258-C002 
(HARRIER) studies was respectively −0.2 letters and –0.7 letters, with a lower limit of the 
95% CI being −2.1 letters (p < 0.0001), and −2.4 letters (p= 0.0001). Intraocular inflammation 
(IOI), an AE of special interest, was observed from 5.3% and 2.7% of the subjects in the 
brolucizumab 6 mg arm in their study eyes up to Week 48, respectively in the RTH258-C001 
(HAWK) and RTH258-C002 (HARRIER) studies.
To demonstrate consistency in efficacy among Chinese subjects with what was observed in 
the two global pivotal studies, a statistical design with an alpha level of 0.1 is considered 
sufficient, which resulted in a sample size of approximately 390 subjects. Moreover, the 
proposed sample size will also provide sufficient evidence for the safety evaluation.  
Assuming similar IOI rates as observed from RTH258-C001 (HAWK) and RTH258-C002 
(HARRIER) studies, with approximately 195 subjects in the brolucizumab arm, there is a 
99.6% and 85.4% probability respectively to observe at least 3 subjects that would experience 
IOI.

Amendment 2 (14-Oct-2021) 
Amendment rationale 
The main purpose of this amendment is to implement the Urgent Safety Measures (USM) 
described in the 10-Aug-2021 Dear Investigator Letter (DIL) into the study protocol.  The 
USM were implemented for ongoing studies not achieving Last Patient Last Visit (LPLV) by 
11-Aug-2021 and in response to the identification of a causal immune-mediated mechanism 
of the previously identified risk of retinal vasculitis (RV), and/or retinal vascular occlusion 
(RO), typically in the presence of intraocular inflammation (IOI) indicating a requirement to 
discontinue treatment with brolucizumab (RTH258) in patients who develop events of RV 
and/or RO.
This amendment also includes information on gender imbalance on IOI following 
brolucizumab treatment and recommendations on the time window for a study subject to 
receive the COVID-19 vaccine. Some other administrative changes have also been 
incorporated.
Changes to the protocol
Changes to specific sections of the protocol are shown in the track changes version of the

Data analysis
Primary analysis data set: The primary data set for all efficacy analyses is the full 
analysis set (FAS) with missing values imputed by last observation carried forward 
(LOCF). The FAS comprises all subjects to whom study treatment has been assigned 
by randomization and who receive at least one IVT injection of the study treatment. 
Primary and key secondary endpoints:
The primary efficacy endpoint is the change from Baseline in BCVA at Week 48.
The first key secondary endpoint is average change in BCVA from Baseline over the 
period Week 36 through Week 48.
Statistical Hypotheses and testing strategy:
The statistical hypothesis for the primary endpoint and first key secondary endpoint is 
non-inferiority of brolucizumab 6 mg to aflibercept 2 mg within a margin of 4 letters. The 
following 2 hypotheses will be tested in the pre-specified hierarchical sequence according 
to their numbering (HAn, n = 1, 2). Consequently, confirmatory testing of the second 
hypothesis requires rejection of the first null hypothesis. In this setting, each hypothesis 
will be assessed at a one-sided significance level of 0.05, while keeping the global type I 
error rate at 0.05. 
The following noninferiority hypotheses are related to a noninferiority margin of 4 letters.

48 = Week 48, 36-48 = Week 36 through 48, R= brolucizumab 6 mg, A= aflibercept 2 mg
H01: μ48R - μ48A ≤ -4 letters vs HA1: μ48R - μ48A > -4 letters
μ48R and μ48A being the corresponding unknown true mean BCVA changes from Baseline 
to Week 48.
H02: μ36-48R - μ36-48A ≤ -4 letters vs HA2: μ36-48R - μ36-48A > -4 letters
μ36-48R and μ36-48A being the corresponding unknown true mean values for the average 
change in BCVA from Baseline over the period Week 36 through 48.
Primary statistical method: For the test of non-inferiority, a two-sided 90% CI for the 
treatment difference will be derived from an analysis of variance (ANOVA) model with 
treatment, Baseline BCVA categories (≤ 55, 56-70, ≥ 71 letters) and age categories (< 
75, ≥ 75 years) as factors. In order to demonstrate non-inferiority, the lower limit of the 
two-sided 90% CI for the treatment difference (brolucizumab 6 mg – aflibercept 2 mg) 
must be greater than -4 letters. 
Sample size justification: In the spirit of bridging concept under ICH E5, A sample size 
of 175 subjects per treatment arm is sufficient to demonstrate noninferiority (margin = 4 
letters) of brolucizumab 6 mg versus aflibercept 2 mg with respect to the BCVA change 
from Baseline to Week 48 at a one-sided alpha level of 0.05 with a power of approximately 
80% assuming equal efficacy and a common standard deviation of 15 letters. A power of 
at least 80% can be expected for the first key secondary endpoint assuming that 
averaging BCVA change from Baseline over the 4 time points will not lead to an increase 
in the standard deviation. To account for a drop-out rate of 10%, a total of 195 subjects 
will be randomized per treatment arm.

Introduction
1.1
Background
Age-related macular degeneration (AMD) is the leading cause of severe vision loss affecting 
10%-13% of people over the age of 65 in North America, Europe, and Australia 
(Smith et al 2001, Rein et al 2009, Kawasaki et al 2010).
There are few data on the epidemiology of AMD in the Asian population. In a Shihpai Eye 
Study (Hsu et al 2004), a population-based cross-sectional study of an elderly Chinese 
population 65 years or older in Taiwan, AMD was the cause of visual impairment in 10.4% of 
the subjects. In the epidemiological study in Shanghai China, it was reported that the prevalence 
of AMD (dry and wet combination) was 15.5% of the overall population that were more than 
50 years old (Li X 2013). The prospective Hisayama study in a Japanese population aged 50 
years or older reported for AMD prevalence of 19.5% in men and of 14.9% in women 
(Miyazaki et al 2003). Considering an aging population and socioeconomic development, it is 
expected that the incidence of visual impairment due to AMD will increase over time in China 
(Wong et al 2008).
AMD is classified into 2 clinical subtypes: the non-neovascular (atrophic) or dry form and the 
neovascular (exudative) or wet form (Ferris 1983, Lim et al 2012, Miller 2013). Neovascular 
AMD is characterized by the growth of abnormal new blood vessels (neovascularization) under 
the retinal pigment epithelium (RPE) or subretinal space from the subjacent choroid, termed 
choroidal neovascularization (CNV) (Ferris et al 1984). These newly formed vessels have an 
increased likelihood to leak blood and serum, damaging the retina by stimulating inflammation 
and scar tissue formation. This damage to the retina results in progressive, severe, and 
irreversible vision loss (Shah and Del Priore 2007, Shah and Del Priore 2009). Without 
treatment, most affected eyes will have poor central vision (20/200) within 12 months 
(Blinder et al 2003). Although the neovascular form of the disease is only present in about 10% 
of all AMD cases, it accounted for approximately 90% of the severe vision loss from AMD 
prior to the introduction of anti-vascular endothelial growth factor (anti-VEGF) treatments 
(Ferris 1983, Sommer et al 1991, Wong et al 2008).
Anti-VEGFs and unmet medical need in treatment of nAMD VEGF has been shown to be 
elevated in patients with neovascular AMD (nAMD), and is thought to play a key role in the 
neovascularization 
process 
(Spilsbury et al 2000). 
The 
use 
of 
intravitreal 
(IVT) 
pharmacotherapy targeting VEGF has significantly improved visual outcomes in patients with 
neovascular AMD (Bloch et al 2012, Campbell et al 2012). Anti-VEGF treatments, such as 
ranibizumab (Lucentis ®) and aflibercept (Eylea ®), inhibit VEGF signaling pathways and have 
been shown to halt the growth of neovascular lesions and resolve retinal edema. However, the 
patient monitoring and treatment burden remain high with approved anti-VEGF therapies.
Currently, three anti-VEGFs are approved for treatment of nAMD in China: ranibizumab 
(Lucentis®), conbercept (Lumitin®) and aflibercept (Eylea®). The Chinese prescribing 
information recommends a loading phase for all anti-VEGFs in nAMD, followed by less 
frequent injections in a comparable range as in other countries. Lucentis® is dosed monthly for 
the first three months, followed by 4 – 5 injections per year or by injections every 3 months, 
but with reduced efficacy compared to monthly dosing. Eylea® is dosed monthly for the first 
three months followed by injections every 2 months (8 weeks), and Lumitin®  is dosed monthly

for the first three months followed by injections every 3 months, while both efficacies compared 
to Lucentis® have not been established.
Physicians have responded to the treatment burden in nAMD by exploring different regimens 
with fewer injections (Gupta et al 2011). In the real-world setting, patients with nAMD may not 
achieve the best possible long-term outcomes (Tufail et al 2014, Holz et al 2014, Chong 2016), 
as vision continues to decline despite anti-VEGF treatment often due to the underutilization of 
treatment and monitoring (Holz et al 2015). Some patients undergo treatment fatigue with anti-
VEGF therapies and choose to discontinue treatment. (Boulanger-Scemama et al 2015). This 
can result in recurrent disease and permanent vision loss (Essex et al 2016). Therefore, unmet 
medical needs for effective and more durable anti-VEGF therapies still exist for patients with 
nAMD (Freund et al 2013).
Brolucizumab development program in nAMD Brolucizumab (RTH258, formerly 
ESBA1008) is a humanized single-chain Fv (scFv) antibody fragment inhibitor of vascular 
endothelial growth factor A with a molecular weight of ~26 kDa. Brolucizumab is an inhibitor 
of VEGF-A and works by binding to the receptor binding site of the VEGF-A molecule, thereby 
preventing the interaction of VEGF-A with its receptors VEGFR1 and VEGFR2 on the surface 
of endothelial cells.
The smaller molecular size of the scFv delivers a higher molar dose, which prolongs the 
therapeutic effect and enables better tissue penetration at the retina, compared to whole 
antibodies and larger antibody fragments. A low molecular weight and high concentration 
gradient between the vitreous and the retina should increase drug distribution into the target site 
of action, ensuring rapid and effective control of anatomical disease activity.Safety, efficacy, 
and pharmacokinetics of brolucizumab in subjects with nAMD were evaluated in the following 
completed clinical studies:

Single ascending dose study of brolucizumab (0.5, 3.0, 4.5 and 6 mg) versus ranibizumab 
0.5 mg (Alcon protocol C-10-083, SEE),

56-week multiple dose study of brolucizumab 6 mg versus aflibercept 2 mg (Alcon 
protocol C-12-006, OSPREY),

Proof-of concept study of two concentrations of brolucizumab (120 mg/mL and 60 
mg/mL) applied as a microvolume injection (10 μL) or infusion (8.3 μL) (Alcon protocol 
C-13-001, OWL),

3 dose study of brolucizumab at 6mg or 3mg in patients of Japanese and non-Japanese 
ancestry (Alcon protocol RTH258-E003 also referred to as CRTH258A2201, SHRIKE).
Two pivotal, two-year, randomized, double-masked, multicenter phase III studies of 
brolucizumab were completed in patients with nAMD: RTH258-C001 (HAWK) and RTH258-
C002 (HARRIER). The primary objective of both studies was to demonstrate noninferiority of 
brolucizumab to aflibercept. Analysis of data up to Week 48 demonstrated noninferiority of 
brolucizumab 3 mg and 6 mg versus aflibercept in mean change in BCVA from Baseline to 
Week 48. A majority of subjects, 56% (HAWK) and 51% (HARRIER), were maintained 
exclusively on a q12w interval following the loading phase through Week 48. Brolucizumab 
was generally well tolerated with overall adverse event rates comparable to aflibercept.
In general, brolucizumab was demonstrated to be safe and well tolerated with an ocular and 
systemic safety profile similar to ranibizumab and aflibercept and non-inferior efficacy as 
compared to ranibizumab and aflibercept.

Since the initial marketing authorization approval in October 2019 for the treatment of nAMD, 
adverse events of retinal vasculitis and/or retinal vascular occlusion, that may result in severe 
vision loss and typically in the presence of intraocular inflammation, have been reported from 
post-marketing experience with brolucizumab (Beovu®). Results of the mechanistic study 
BASICHR0049 on blood samples from nAMD patients exposed to brolucizumab and having 
subsequently developed retinal vasculitis and/or retinal vascular occlusion, taken together with 
accumulated data from HAWK, HARRIER and CRTH258AUS04 (MERLIN), regarding the 
association of treatment-emergent immunogenicity and IOI, indicate a causal link between the 
treatment-emergent immune reaction against brolucizumab and the brolucizumab-related 
retinal vasculitis and/or retinal vascular occlusion, typically in the presence of IOI. Considering 
the incidence of these events is uncommon, the overall risk/benefit assessment remains positive. 
Please refer to the Brolucizumab Investigator’s Brochure (IB) for further details.

Week 48 visits (no scheduled treatment for any arm),

disease activity assessment (DAA) will be performed for both arms at protocol specified 
visit,

to fulfill the double-masking requirement, the investigational site will have masked and 
unmasked staff.
Non-inferiority testing related to the primary efficacy parameter Best-corrected visual acuity 
(BCVA) will be based on a margin of 4 letters. This non-inferiority margin provides assurance 
that any proof of non-inferiority only occurs if the observed treatment differences are of no 
clinical relevance.
The patient population will be described in more detail in Section 5.
4.2
Rationale for dose/regimen and duration of treatment
The dose and regimen for brolucizumab are based on:

The performed analysis of data up to Week 48 from the two phase III brolucizumab 
studies (HAWK and HARRIER) in nAMD, brolucizumab 6 mg and 3 mg doses showed 
comparable efficacy and safety profiles to aflibercept 2 mg.

The numerical differences between the 3 mg and 6 mg dose seen in the functional and 
anatomical endpoints, in the proportion of subjects on a q12w dosing regimen and in the 
control of disease activity consistently favor the 6 mg dose. Overall, the safety of
brolucizumab 6 mg was comparable to the 3mg dose. Hence, brolucizumab 6 mg dose will 
be used in this study.
Aflibercept will be administered as per the approved label in China.
Route of administration is intravitreal injection as for all anti-VEGF treatments currently 
approved for treatment of nAMD.
Study duration of 48 weeks is deemed sufficient to assess efficacy and safety of brolucizumab 
6 mg administered at the target q12w dosing regimen. The 2 year data of the aflibercept studies 
(View 1 and View 2) showed that the mean BCVA change from Baseline reaches a plateau 
during the first year of treatment, which to a large degree is sustained during the second year 
(Schmidt-Erfurth et al 2014). Similar results were observed in the ranibizumab study 
(Li et al 2016) with Chinese population that BCVA improvement in the first year was 
maintained during the second year. Also the brolucizumab Phase III studies (HAWK and 
HARRIER) used the time point of 48 weeks for the primary endpoint and also showed that 
BCVA reached a plateau during the first year of treatment.
4.3
Rationale for choice of control drugs (comparator/placebo) or 
combination drugs
Aflibercept 2 mg is an established standard of care anti-VEGF treatment for nAMD in US and 
EU, which has been recently approved in China in May 2018.
Aflibercept has been chosen as a comparator in two recently completed global brolucizumab 
Phase III studies RTH258-C001 (HAWK) and RTH258-C002 (HARRIER) due to the 
consistency of the approved dose and posology of aflibercept in most countries worldwide.

Using the same comparator as in the global pivotal studies will support the comparison of the 
results between China and global study populations.
Due to the well-established efficacy of anti-VEGF treatments in the indication of nAMD, an 
internal validation of this study via a placebo arm is ethically not acceptable.

4.5
Risks and benefits
The risk to subjects in this trial may be minimized by compliance with the eligibility criteria 
and study procedures, as well as close clinical monitoring, and periodic review of safety data 
by an independent program level data monitoring committee (DMC).
Women of childbearing potential and sexually active males must be informed that taking the 
study treatment may involve unknown risks to the fetus if pregnancy were to occur during the 
study, and agree that in order to participate in the study they must adhere to the contraception 
requirements outlined in the exclusion criteria. If there is any question that the patient will not 
reliably comply, they should not be entered or continue in the study.
Brolucizumab is an inhibitor of VEGF with a mechanism of action similar to ranibizumab or 
aflibercept with a smaller molecular size (26 kDa and 48 kDa or 115 kDa, respectively). 
Ranibizumab and aflibercept (both approved inhibitors of VEGF-A) have consistently 
demonstrated efficacy in VEGF-driven retinal pathologies, including nAMD, with benefits 
outweighing the risks. Assuming a corresponding class-effect, it is justified to expect that 
brolucizumab (having the same MoA as ranibizumab and aflibercept) will likewise be 
efficacious and have a similar safety profile in the nAMD indication. In both Phase III studies 
(HAWK, HARRIER) in nAMD, brolucizumab demonstrated non-inferiority to aflibercept in 
mean change in BCVA from Baseline to Week 48. These results were achieved while a 
majority of patients on brolucizumab 6 mg – 56% in HAWK and 51% in HARRIER – were 
maintained on a q12w dosing interval following the loading phase through Week 48, i.e. with 
a reduced treatment frequency compared to aflibercept. Brolucizumab safety was comparable 
to aflibercept, with the overall incidence of adverse events balanced across all treatment 
groups in both studies. Retinal vasculitis and/or retinal vascular occlusion, typically in the 
presence of IOI has been reported following brolucizumab injection. These immune mediated 
adverse events may occur following the first intravitreal injection. Discontinuation of study 
treatment is required in subjects who develop these events. In addition, subjects who 
experience IOI may be at risk of developing retinal vasculitis and/or retinal vascular occlusion 
and should be closely monitored.
Based on clinical studies, IOI related adverse events, including retinal vasculitis and retinal 
vascular occlusion, were reported more frequently in female patients treated with 
brolucizumab than male patients (e.g. 5.3% females vs. 3.2% males in HAWK and 
HARRIER, Novartis data on file).
Overall, brolucizumab was well tolerated in clinical studies with nAMD subjects when 
treatment interval is not less than every 8 weeks after the first 3 monthly initial doses (loading 
phase). The risk/benefit assessment for brolucizumab remains positive.

population will be representative of all eligible subjects.
In cases where both eyes are eligible, the eye with the worse BCVA at Baseline will be selected 
as the study eye. If both eyes have the same BCVA, it is recommended to select the right eye 
as the study eye.

Concomitant therapy
The investigator must instruct the patient to notify the study site about any new medications 
he/she takes after signing the study informed consent. All medications, procedures and 
significant non-drug therapies (including physical therapy and blood transfusions) administered 
after the patient was enrolled into the study must be recorded in the appropriate electronic case 
report form (eCRF) page.
Each concomitant drug must be individually assessed against all exclusion criteria/prohibited 
medication. If in doubt the investigator should contact the Novartis medical monitor before 
randomizing a patient or allowing a new medication to be started. If the subject is already 
enrolled, contact Novartis/sponsor to determine if the subject should continue participation in 
the study.
6.2.1.1
Permitted concomitant therapy requiring caution and/or action
Non-investigational treatment for fellow eye is permitted at the discretion of the investigator 
and in accordance with the administration procedures established at the study center. Such 
treatment must be recorded on the appropriate Case Report/Record Form (CRF).
Administration of topical ocular corticosteroids are permissible in the study eye during the 
course of the study. If the subject is planning to receive a COVID-19 vaccine that is authorized 
by local regulation, it is recommended to receive the vaccine at least 7 days before or after the

6.3
Subject numbering, treatment assignment, randomization
6.3.1
Subject numbering
Each subject is identified in the study by a Subject Number (Subject No.), that is assigned when 
the patient is first enrolled for screening and is retained as the primary identifier for the subject 
throughout his/her entire participation in the trial. The Subject No. consists of the Center 
Number (4 digit number for Center No. as assigned by Novartis to the investigative site) with a 
sequential subject number (3 digit number) suffixed to it, so that each subject is numbered 
uniquely across the entire database.
Upon signing the informed consent form, the patient is assigned to the next sequential Subject 
No. available in electronic data capture (EDC) system. The investigator or her/his staff will 
contact the Interactive Response Technology (IRT) and provide the requested identifying 
information for the patient to register them into the IRT. Once assigned to a patient, the patient 
number will not be reused for another patient. If the patient fails to be randomized for any reason, 
the IRT must be notified within 2 days that the patient was not randomized. The reason for not 
being randomized will be entered on the Screening Log, and the Demography eCRF should be 
completed. Patients who have been screen failures but are re-screened (see Section 8.1) will be 
assigned a new Subject No.
6.3.2
Treatment assignment, randomization
At Baseline visit, all eligible patients will be randomized via Interactive Response Technology 
(IRT) to one of the treatment arms, in a ratio of 1:1. There are no stratification factors in this 
study.
The investigator or her/his delegate will contact the IRT, after it was confirmed that the patient 
fulfills all the inclusion and none of the exclusion criteria. The IRT will assign a randomization 
number to the patient, which will link the patient to a treatment arm.
The randomization numbers will be generated using the following procedure to ensure that 
treatment assignment is unbiased and concealed from patients and investigator staff. A patient 
randomization list will be produced by the IRT provider using a validated system that automates 
the random assignment of patient numbers to randomization numbers. These randomization 
numbers are linked to the different treatment arms. A separate medication list will be produced 
by or under the responsibility of Novartis Global Clinical Supply using a validated system that 
automates the random assignment of medication numbers to packs containing the study 
treatment.
The randomization scheme for patients will be reviewed and approved by a member of the 
Randomization Group.
6.4
Treatment masking
The intent of masking is to limit the occurrence of conscious and unconscious bias in the 
conduct and interpretation of the clinical study. Bias could arise from the influence that the 


Novartis
Confidential
Page 35
Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
knowledge of a specific treatment assignment may have on the recruitment and allocation of 
subjects, their subsequent care, the assessment of end points, the handling of withdrawals, and 
so on. The essential aim of masking, therefore, is to prevent identification of the treatments by 
the investigator, subject, and others associated with the conduct of the study until all such 
opportunities for bias have passed.
This study will be double-masked, with patients randomized to be treated with brolucizumab 6 
mg or aflibercept 2 mg. All members of the Sponsor team will be masked to treatment 
assignments while the study is in progress. In addition, the biostatistician who is directly 
involved in the conduct of the study (i.e. involved in subject level discussions or direct 
interaction with sites) will remain masked to treatment assignments while the study is in 
progress. Sponsor personnel who have access to treatment codes will not divulge the codes to 
subjects, investigators, site staff or Sponsor.
Unmasking of investigators and personnel directly involved in the conduct of the study will 
only occur in the case of subject emergencies (Section 6.6.2), and then at the time of the final 
analysis (Section 11), at the conclusion of the study.
In the event of a medical emergency or an adverse event (AE) during the study where the 
knowledge of subject treatment is required (e.g. in case of Suspected Unexpected Serious 
Adverse Reactions (SUSAR)), an individual investigator will have the ability to unmask the 
treatment assignment for a specific subject. The investigator should notify the Sponsor prior to 
unmasking a subject, if there is sufficient time. Further, the Sponsor must be informed whenever 
the randomization code is broken and be informed about the reasons for unmasking.
Each site must have both masked and unmasked investigators available. The investigator who 
performs the injection will be unmasked to the treatments as will any other site personnel who 
have been delegated responsibility for working with the IP. The unmasked site personnel and 
unmasked injecting investigator must not perform BCVA, complete ophthalmic examination, 
disease activity assessments or administer the VFQ-25. Also, the unmasked site personnel and 
unmasked injecting physician must not perform assessment of any ocular or non-ocular safety 
parameters, or assess causality AEs for subjects during the course of the study except an event 
reported immediately following IVT injection.
The unmasked investigator/site personnel should, however, assess subject safety immediately 
following injection. Once the designated roles are determined, the unmasked investigator/site 
personnel not be switched at any time after randomization to masked role. Every effort must be 
made to limit the number of unmasked study personnel to ensure the integrity of this masked 
study.
Treatment masking of individual subjects will remain intact until the final database lock has 
occurred by ensuring: Randomization data are kept strictly confidential until the time of 
unmasking and will not be accessible by anyone else involved in the study except the 
unmasked/treating investigator. During and after database lock at Week 48, the masked 
personnel and subjects will remain masked to the treatment assignment until the conclusion of 
the study.
Unmasked monitors will be available to perform study medication accountability and to deal 
with study issues involving the unmasked investigator or unmasked site staff.

Additional treatment guidance
6.6.1
Treatment compliance
Every time the study treatment is to be administered, IRT needs to be accessed for the 
medication (kit) number. The date and time of all study treatment injections administered during 
the study and any deviations from the protocol treatment schedule will be captured by the 
unmasked investigator staff or by unmasked field monitor on the appropriate study treatment 
dispensing form.

Exposure to the study treatment will be based on the number of injections administered. 
Compliance with the study treatment will be assessed by the unmasked field monitor at each 
visit using vial counts and information provided by the pharmacist or by the investigator.
The type, reason for use, start and stop dates (or “ongoing”) of all concomitant medications 
administered during the study will be collected on the Concomitant medications CRF.
6.6.2
Emergency breaking of assigned treatment code
Emergency code breaks must only be undertaken when it is required to in order to treat the 
subject safely. Most often, study treatment discontinuation and knowledge of the possible 
treatment assignments are sufficient to treat a study subject who presents with an emergency 
condition. Emergency treatment code breaks are performed using the IRT. When the 
investigator contacts the system to break a treatment code for a subject, he/she must provide 
the requested subject identifying information and confirm the necessity to break the treatment 
code for the subject. The investigator will then receive details of the investigational drug 
treatment for the specified subject and a fax or email confirming this information. The system 
will automatically inform the Novartis monitor for the site and the study team that the code 
has been broken.
If the treatment code needs to be broken in the interest of subject safety, the investigator is 
encouraged to contact an appropriate Sponsor representative prior to unmasking if there is 
sufficient time.
It is the investigator’s responsibility to ensure that there is a dependable procedure in place to 
allow access to the IRT/code break cards at any time in case of emergency. The investigator 
will provide:

protocol number

study drug name (if available)

subject number
In addition, oral and written information to the subject must be provided on how to contact 
his/her backup in cases of emergency, or when he/she is unavailable, to ensure that unmasking 
can be performed at any time.
The appropriate personnel from the site and Sponsor will assess whether study treatment should 
be discontinued for any subject whose treatment code has been broken for any reason.
6.7
Preparation and dispensation
Each study site will be supplied with study drug.
The study drug packaging has a 2-part label. A unique medication number is printed on each 
part of this label. Unmasked study staff will identify the study drug package(s) to dispense to 
the patient by contacting the IRT and obtaining the medication number(s). Immediately before 
dispensing the medication kit to the patient, investigator staff will detach the outer part of the 
label from the packaging and affix it to the source document (Drug Label Form) for that 
patient’s unique patient number.

Handling of study treatment and additional treatment
6.7.1.1
Handling of study treatment
Study treatment must be received by a designated person at the study site, handled and stored 
safely and properly and kept in a secured location to which only the unmasked investigator and 
designated site personnel have access. Upon receipt, all study treatment must be stored 
according to the instructions specified on the labels and in the IB. Clinical supplies are to be 
dispensed only in accordance with the protocol. Technical complaints are to be reported to the 
respective Novartis Country Organization (CO) Quality Assurance.
Medication labels will be in the local language and comply with the legal requirements of each 
country. They will include storage conditions for the study treatment but no information about 
the subject except for the medication number.
The unmasked investigator designated site personnel must maintain an accurate record of the 
shipment and dispensing of study treatment in a drug accountability log. Monitoring of drug 
accountability will be performed by unmasked monitors during site visits or remotely and at the 
completion of the trial. Study site will be asked to return all unused study drug and packaging.
At the conclusion of the study, and as appropriate during the course of the study (eg. at the time 
of discontinuation of study treatment), the investigator will return all unused study treatment, 
packaging, drug labels, and a copy of the completed drug accountability log to the Novartis 
unmasked monitor or to the Novartis address provided in the investigator folder at each site.
6.7.1.2
Handling of additional treatment
6.7.2
Instruction for prescribing and taking study treatment
All kits of study treatment assigned by the IRT will be recorded/databased in the IRT.
There will be two treatment phases for IVT injections with different timing for brolucizumab 
and aflibercept treatment arms (loading phase and maintenance phase).
Brolucizumab 6 mg will be administered by IVT injection in accordance with supplied 
instructions for use. Subjects in the brolucizumab 6 mg arm will receive loading doses at 
Baseline, Week 4 and Week 8. After the loading doses, subjects will receive q12w treatment 
unless there is disease activity as assessed by the investigator during one of the scheduled DAA 
visits. If disease activity is identified, the subject will be assigned to receive injections q8w 
thereafter, up to Week 44.
Aflibercept 2 mg will be administered by IVT injection in accordance with instructions for use 
specified in the label. Subjects in the aflibercept 2 mg arm will receive loading doses at Baseline, 
Week 4 and Week 8. After the loading doses, subjects will receive q8w treatment starting at 
Week 16 and up to Week 40. DAAs will be conducted by the evaluating/masked investigator 
for masking purposes and will not influence the treatment interval.
The IVT injection procedure for brolucizumab and aflibercept, including aseptic and 
antimicrobial requirements, will be performed according to local clinical practice. 
The sham injection should mimic an IVT injection including the aseptic and antimicrobial

requirements. The tip of the sham injection syringe (the hub without a needle) will be placed 
on the eye for the approximate amount of time it would take to perform an IVT injection. 
In both treatment arms, there will be no treatment injection administration on Week 12 and 48.
Figure 6-1
Dosing schedule
Disease activity assessment (DAA)
The concept of the brolucizumab q12w/q8w regimen is to allocate subjects according to their 
individual treatment needs to either a q12w or a q8w treatment schedule. The initial schedule is 
q12w and a subject will remain on q12w as long as the masked investigator does not identify 
disease activity which in his opinion requires more frequent anti-VEGF treatment.
Disease activity will be assessed by the masked Investigator for all subjects in order to maintain 
masking. The assessment will only be performed at the prespecified DAA visits at:

Week 16 and Week 20, during the first q12w treatment interval (i.e. for brolucizumab 
subjects 8 and 12 weeks after the last loading injection) to make sure that subjects with a 
high treatment need are identified early on,

Week 32, following second q12w treatment interval

Week 44, to document the adequacy of the q12w treatment schedule at the end of 
treatment (EOT) period (without having impact on the subject's treatment schedule).
The assessment of the disease activity is at the discretion of the masked investigator. He/she 
should apply their own expert judgement when assessing q8w treatment need. Disease activity 
criteria outlined below might be considered as guidance.
Disease activity criteria at Week 16:

Decrease in BCVA of ≥ 5 letters compared with Baseline

Decrease in BCVA of ≥ 3 letters and CSFT increase ≥ 75μm compared with Week 12

Decrease in BCVA of ≥ 5 letters due to nAMD disease activity compared with Week 12


Novartis

Page 40
Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307

New or worse intraretinal cysts (IRC) / intraretinal fluid (IRF) compared with Week 12
Disease Activity Criterion at Weeks 20, 32 and 44:

Decrease in BCVA of ≥ 5 letters due to nAMD disease activity compared with Week 12
If DAA reveals a need for q8w treatment the subject will be assigned to receive injections q8w 
thereafter, up to the end of the study. Only DAA at the scheduled DAA visits have an impact 
on the subject’s treatment schedule (except Week 44).
The outcome of the DAA will be captured in the IRT system. The IRT system will make the 
necessary changes to the dosing schedule as per the masked investigator’s assessment of disease 
activity.
A subject randomized to brolucizumab 6 mg who misses Week 16 will undergo disease activity 
assessment at Week 20 as he/she would have done if the visit had not been missed. If, however, 
subject misses Week 20 or Week 32 visit, then the subject will be assumed to have had a q8w 
treatment need at this missed visit and will be assigned to a q8w schedule at the next visit (i.e. 
at the next visit the subject will receive an active injection) up to study exit. The IRT system 
will make the necessary changes once the missed visit is registered.
Intravitreal injection
The IVT injection will be carried out under controlled, aseptic conditions per local clinical 
practice and in accordance with supplied instructions for use (brolucizumab 6 mg) or 
instructions for use specified in the label (aflibercept 2 mg).
The study eye will be assessed before and after intravitreal injection to ensure that the procedure 
and/or the study treatment had not endangered the health of the eye.
An IVT injection is contraindicated in patients with active ocular or periocular infections and 
in patients with active intraocular inflammation (IOI); therefore, the investigator must verify 
that these conditions are not present in study eye prior to every injection.
If any signs of intraocular inflammation is present, then an IVT injection must not be performed. 
Additional ophthalmic examination and imaging should be performed to evaluate IOI (see 
Section 8.4.3).
If IOI is confirmed, subjects should be treated for IOI according to clinical practice and closely 
monitored since they may be at risk of developing retinal vasculitis and/or retinal vascular 
occlusion. If subject develops retinal vasculitis and/or retinal vascular occlusion based on the 
investigator’s evaluation, the study treatment must be discontinued.
All kits of study treatment assigned by the IRT will be recorded in the IRT system.
Date and time of every injection administered to the subject will be recorded in the CRF.
Sham injection
At all applicable visits from Week 16 to Week 44, inclusive, a sham treatment will be performed
to maintain subject masking. For the sham treatment the tip of an injection syringe (the hub 
without a needle) will be used.

Informed consent procedures
Eligible patients may only be included in the study after providing (witnessed, where required 
by law or regulation), IEC approved informed consent.
If applicable, in cases where the patient's representative(s) gives consent (if allowed according 
to local requirements), the patient must be informed about the study to the extent possible given 
his/her understanding. If the patient is capable of doing so, he/she must indicate agreement by 
personally signing and dating the written informed consent document.
Informed consent must be obtained before conducting any study-specific procedures (e.g. all of 
the procedures described in the protocol). The process of obtaining informed consent must be 
documented in the patient source documents.
Novartis will provide to investigators in a separate document a proposed informed consent form 
that complies with the ICH GCP guidelines and regulatory requirements and is considered 
appropriate for this study. Any changes to the proposed consent form suggested by the 
investigator must be agreed by Novartis before submission to the IRB/IEC.
Information about common side effects already known about the investigational drug can be 
found in the IB. This information will be included in the patient informed consent and should 
be discussed with the subject during the study as needed. Any new information regarding the 
safety profile of the investigational drug that is identified between IB updates will be 
communicated as appropriate, for example, via an investigator notification (IN) or an aggregate 
safety finding. As new information becomes available, informed consent to be updated and then 
must be discussed with the subject.
Women of child bearing potential must be informed that taking the study treatment may involve 
unknown risks to the fetus if pregnancy were to occur during the study and agree that in order 
to participate in the study they must adhere to the contraception requirements.
Male patients must be informed that if a female partner becomes pregnant while he is enrolled 
in the study, contact with the female partner will be attempted to request her consent to collect 
pregnancy outcome information.
A copy of the approved version of all consent forms must be provided to Novartis/sponsor after 
IRB/IEC approval. 
During the COVID-19 pandemic that may challenge the ability to obtain a standard written 
informed consent due to limits that prevent an on-site visit, the Investigator may conduct the 
informed consent discussion remotely (e.g. telephone, videoconference). Guidance issued by 
local regulatory bodies on this aspect prevail and must be implemented and documented (e.g. 
the presence of an impartial witness, sign/dating separate informed consent forms (ICFs) by 
trial participant and person obtaining informed consent, etc.). Remote informed consent should 
be appropriately documented and confirmed by way of standard informed consent procedures 
at the earliest opportunity when the subject will be back at the trial sites.

Visit schedule and assessments
Assessment schedule lists all of the assessments and indicates with an “X”, the visits when they 
are performed. All data obtained from these assessments must be supported in the subject’s 
source documentation.
Subjects should be seen for all visits/assessments as outlined in the assessment schedule or as 
close to the designated day/time as possible. Missed or rescheduled visits should not lead to 
automatic discontinuation. Subjects who prematurely discontinue the study for any reason 
should be scheduled for a visit as soon as possible, at which time all of the assessments listed 
for the final visit will be performed. At this final visit, all dispensed investigational product 
should be reconciled, and the adverse event and concomitant medications recorded on the CRF.
If the COVID-19 pandemic limits or prevents on-site study visits, study treatment could not be 
administered and other study assessments may not be performed. Alternative methods of safety 
monitoring may be implemented. Depending on local regulations, site capabilities and patient’s 
visit status in the study, phone calls or virtual contacts (e.g. teleconsult) can be performed for 
safety follow-up for the duration of the pandemic, until it is safe for the participant to visit the 
site again.

2 All exit procedures should be followed, regardless of when the subject exits the study. Visit should be at least 4 weeks from last dose of study treatment. Patient report 
outcome (PRO) will not be administered on EOS if different from Week 48 visit.
3 Must be signed/dated prior to performing any study procedures, including screening procedures.
4 All clinically significant findings will be recorded as medical history or adverse events, as appropriate. Includes height and weight.
5 If PK Consent was provided (in subset of PK subjects).
6 In case there is an elevated blood pressure measurement as specified in the exclusion criteria the blood pressure measurement should be repeated after 20 minutes. If 
the repeat measurement is elevated, then the patient is not eligible to be enrolled into the study.
7 Required for all female subjects of childbearing potential. Urine pregnancy test will be performed unless local regulations require a serum pregnancy test.
8 All blood draws and collection of urine should be performed prior to receiving the IVT or sham injection and prior to injection of fluorescein dye.
9 Both eyes
10 Includes fundus and slit lamp examination. Pupil dilation for the fundus examination is at the discretion of the Investigator.
13 Patients will be randomized to brolucizumab 6 mg/50 µL or aflibercept 2 mg/50 µL.
14 Beginning at Week 16, when subjects do not receive an active injection, they will receive a sham injection. The injection may be performed at a later time, as long as it 
is within 7 days of the scheduled visit and within the visit window.
15 No need to additionally collect PK blood at visit 6 for PK consent participants. The blood drawn for anti-drug antibody in blood could also be used for PK analysis at the 
same visit.

Screening
Screening
A screening period of up to 2 weeks will be used to assess eligibility. The screening period 
starts with the signing of the ICF.
One time rescreening of patients will be allowed, except for the purpose of capturing new 
BCVA or imaging assessments that previously failed to qualify the patient. As long as testing 
can be repeated within 14 days of the first screening, the other screening assessments do not 
need to be repeated. If rescreening is to occur beyond 14 days from the original screening visit 
date, then all screening procedures must be repeated.
Medical judgement should be exercised to ensure that treatment is not withheld in order for a 
patient to participate in the study.
8.1.1
Information to be collected on screening failures
All patients who have signed informed consent but not entered into the next period will have 
the study completion eCRF pages for the screening period, demographics, inclusion/exclusion, 
and serious adverse event (eSAE) data collected. Adverse events that are not SAEs will be 
followed by the investigator and collected only in the source data.
Patients who are randomized and fail to start treatment, e.g. patients randomized in error, will 
be considered an early terminator. The reason for early termination will be recorded on the 
appropriate CRF.
8.2

Investigators will have the discretion to record abnormal test findings on the medical history 
CRF whenever in their judgment, the test abnormality occurred prior to the informed consent 
signature.
8.3
Efficacy
The following assessments will be performed to evaluate the effect of brolucizumab and 
aflibercept on visual function, retinal structure and vascular leakage:

Best-corrected visual acuity with ETDRS-like chart at initial testing distance of 4 meters,

Optical Coherence Tomography,

Color Fundus Photography and Fluorescein Angiography.
8.3.1
Visual acuity
Visual acuity will be assessed at every study visit using best correction determined from 
protocol refraction (BCVA). BCVA measurements will be taken in a sitting position using Early 
Treatment Diabetic Retinopathy Study (ETDRS) visual acuity testing charts. The details of the 
procedure and training materials are provided in the applicable manual. Certification of the 
assessment procedures and assessors will occur prior to any evaluation of study patients.
8.3.2
Optical coherence tomography
Spectral Domain Optical Coherence Tomography (SD-OCT) will be assessed in the study eye 
at every study visit and in both eyes at screening and EOS.
These assessments will be performed by certified technician or investigator at the sites and 
should be performed prior to any study drug administration. Certification of the equipment and 
examiners at each investigative site will occur prior to evaluation of study patients. Masked 
evaluating investigators will evaluate the SD-OCT to assess the status of disease activity. The 
SD-OCT machine used for an individual patient should not change for the duration of the study.
The images will be reviewed by a Central Reading Center (CRC) to ensure a standardized 
evaluation. At screening, SD-OCT images will be submitted to the CRC for determination of 
eligibility. For further procedural details, the investigator should refer to applicable manual 
provided by the CRC.
8.3.3
Color fundus photography and fluorescein angiography
Color fundus photography and fluorescein angiography (FA) will be performed in both eyes at 
screening and EOS and in the study eye only at Week 12.
These assessments will be performed by certified technician or investigator at the sites and 
should be performed prior to any study drug administration. Certification of the equipment and 
examiners at each investigative site will occur prior to evaluation of study patients.
The images will be reviewed by a CRC to ensure a standardized evaluation. At screening, retinal 
images will be submitted to the CRC for determination of eligibility. FA images from previous 
routine evaluations may be used for the screening FA as long as they were performed within 14 
days of the screening visit using CRC-certified equipment and examiners. For further 
procedural details, the investigator should refer to applicable manual provided by the CRC.

Additional images will be taken in case of any signs of intraocular inflammation. Optical 
coherence tomography, color fundus photography and fluorescein angiography (preferably 
wide-field or with peripheral sweeps) should be performed for safety evaluation as described in 
Section 8.4.3.
 
 
 
 
 
 
8.3.5
Appropriateness of efficacy assessments
The selected efficacy assessments are the ones used in the clinical practice to assess the 
functional and anatomical changes of the affected macular area due to nAMD. BCVA as a 
measure of retinal function and SD-OCT images to analyze anatomical changes are standard 
assessments to monitor nAMD and potential treatment effects in routine practice and clinical 
trials. Likewise established FA is used to assess the type of CNV lesion and determine the 
vascular leakage; and Color Fundus that helps classifying potential presence of retinal 
pathology such as fibrosis or geographic atrophy.
8.4
Safety
Safety assessments are specified below with the assessment schedule detailing when each 
assessment is to be performed. If the COVID-19 pandemic limits or prevents on-site study visits, 
phone calls or virtual contacts should be conducted for safety monitoring and discussion of the 
subject´s health status, until the subject can again visit the site.
For details on AE collection and reporting, refer to AE section.
Assessment
Specification
Physical examination
A complete physical examination will include the examination of general 
appearance, skin, neck (including thyroid), eyes, ears, nose, throat, lungs, heart, 
abdomen, back, lymph nodes, extremities, vascular and neurological. The 
examination will be performed at screening and at EOT/EOS visit.
Information for all physical examinations must be included in the source 
documentation at the study site. Clinically relevant findings that are present prior to
signing informed consent must be included in the eCRF capturing Medical History. 
Significant findings made after signing informed consent which meet the definition of 
an Adverse Event must be recorded on the appropriate AE eCRF page.
Vital signs
Sitting blood pressure and pulse rate will be collected at all visits before treatment. 
Vital signs include assessment of sitting blood pressure (systolic and diastolic 
pressure in mm Hg) and pulse (beats per minute). In case there is an elevated blood 
pressure measurement as specified in the exclusion criteria, at the screening or 
Baseline visits, the blood pressure measurement should be repeated after 20 
minutes. If the repeat measurement is elevated, then the patient is not eligible to be 
enrolled into the study.

Assessment
Specification
On days when study drug is administered, vital signs will be measured before 
administration of study medication. The results will be recorded in the eCRF.
Height and weight
Height and weight will be measured at the screening visit only as part of the physical 
examination.
Height in centimeters (cm) and body weight (to the nearest 0.1 kg, in indoor clothing 
but without shoes) will be measured at screening only. The results will be recorded 
in the eCRF.
8.4.1
Laboratory evaluations
A central laboratory will be used for analysis of all specimens collected at applicable visits. 
Details on the collections, shipment of the samples and reporting of the results by the central 
laboratory are provided to investigators in the laboratory manual.
Clinically significant abnormalities must be recorded on the relevant section of the medical 
history/current medical conditions/AE eCRF page as appropriate.
The following laboratory evaluations will be performed:


(WBC) count with differential (absolute and percentage of neutrophils, lymphocytes, 
monocytes, eosinophils, and basophils), and quantitative platelet count.

Clinical chemistry: Blood urea nitrogen (BUN), serum creatine, BUN/Creatinine ratio, 
uric acid, cholesterol, triglycerides, albumin, total globulin, albumin/globulin (A/G) ratio, 
total serum iron, total protein, serum electrolytes (sodium, potassium, bicarbonate, 
chloride, calcium, magnesium), phosphate, glucose and the following liver function tests 
(LFTs): serum aspartate transaminase [AST (SGOT)], serum alanine transaminase [ALT 
(SPGT)], alkaline phosphatase, gamma glutamyl transminase (GGT), total bilirubin, direct 
bilirubin, indirect bilirubin, and lactate dehydrogenase (LDH).

Urinalysis: specific gravity, pH, color, glucose, blood, ketones, bilirubin, and microscopic 
examination (WBC, RBC, epithelial cells, bacteria, mucus, casts, and crystals).
If the COVID-19 pandemic limits or prevents on-site study visits, the method of collection of 
samples may be modified by Novartis if applicable and if modified, will be communicated to 
the Investigator.
8.4.2
Pregnancy and assessments of fertility
High effective contraception is required for women of childbearing potential during the study 
and for 3 months after stopping the investigational medication.
Medical documentation of oophorectomy, hysterectomy, or tubal ligation must be retained as 
source documents. Subsequent hormone level assessment to confirm the woman is not of child 
bearing potential must also be available as source documentation in the following cases:
1. Surgical bilateral oophorectomy without a hysterectomy,
2. Reported 12 months of natural (spontaneous) amenorrhea with an appropriate clinical 
profile.
In the absence of the above medical documentation, FSH testing is required of any female 
patient, regardless of reported reproductive/menopausal status at screening/Baseline.

Protocol No. CRTH258A2307
All pre-menopausal women who are not surgically sterile will have pregnancy testing. 
Additional pregnancy testing might be performed if requested by local requirements.
A urine pregnancy test will be conducted for all women of childbearing potential to assess 
pregnancy before inclusion into the study at screening visit and then at EOT/EOS visit. During 
study, monthly urine pregnancy testing will be performed and results captured in the source 
documents.
8.4.3
Ophthalmic examination
The ophthalmic exam will be performed in the study eye at every study visit and in both eyes 
at screening and EOT/EOS. If study visit assessments and a corresponding treatment occur on 
separate days, ophthalmic examinations should be performed as safety check-up before 
treatment of the study eye.
The ophthalmic exam will consist of the following:
Anterior biomicroscopy (slit lamp examination ) will be completed at every visit (scheduled 
and unscheduled) to examine the anterior segment structures (e.g., eyelids/lashes, conjunctiva, 
cornea, anterior chamber, iris, lens and anterior part of the vitreous) of the study eye (Additional 
examination of the fellow eye will be done at the discretion of the investigator). The outcome 
of the examination will be recorded in the source documents.
Slit lamp examination must be carefully performed before study treatment for signs of IOI. If 
there is any signs of IOI, severity of anterior chamber cells and flare should be assessed 
according to the standardization uveitis nomenclature (SUN) working group grading 
system.(Jabs et al., 2005). The test results will be recorded in the source documents (e.g., 
ophthalmic examination tool) and captured in the appropriate eCRF as applicable. 
Measurement of Intraocular pressure measurement (IOP) will be conducted according to 
the routine clinical practice (using an applanation tonometer, non-contact tonometer, or 
Tonopen). The same method should be used throughout the study for each patient. If dilation is 
required, IOP must be measured prior to the use of dilating drops. The IOP will be assessed in 
the study eye, pre-dose and post-dose at every scheduled visit. The values recorded in mmHg 
will be entered into the eCRF.  
Treatment and close monitoring of IOP should be performed by the investigator for any non-
transient elevation in intraocular pressure (≥25 mmHg). Intravitreal procedure is not 
recommended unless normalization of the IOP has been achieved. Post dose IOP should be 
assessed after every IVT injection, within 60 minutes after injection and if ≥25 mmHg, 
assessment should be repeated until back to normal.
Monitoring of optic nerve head perfusion may be appropriate within 30 minutes after injection, 
at the discretion of the investigator and/or according to the local requirements/practices. Results 
of these procedures will be recorded in the source documents, only if the findings constitute an 
AE they have to be recorded in the eCRF.
Posterior segment (indirect fundus) examination will be conducted by the investigator at the 
screening visit for both eyes. An examination of the peripheral retina must also be conducted 
to ensure that the intravitreal injection can be safely performed. Posterior segment examination 
must be performed carefully before each study treatment. The results of the examination

Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
including any abnormalities (e.g. vitreous cells/haze, retinal tear/detachment, hemorrhage and 
vascular occlusion, vasculitis, etc.) should be recorded in the source documents. If there are any 
signs of IOI, vitreous cells and haze should be assessed using National Institutes of Health (NIH) 
grading system (Nussenblatt et al., 1985). The outcome of the examination will be documented 
in the source document (e.g. ophthalmic examination tool) and appropriate eCRF page as 
applicable. 
Instruct the patient to contact the site for any changes in vision or any symptoms of 
inflammation between scheduled visits. Every effort should be made to bring the subject 
for immediate examination. When IOI, retinal vasculitis, and/or retinal artery occlusion (RAO) 
is present or suspected during a visit, investigators must perform thorough ophthalmic 
examination, and conduct optical coherence tomography, fluorescein angiography and color 
fundus photography (preferably wide-field or with peripheral sweeps). These additional 
assessments will be documented in the source and appropriate eCRF pages as applicable. The 
images are requested to be uploaded onto the CRC portal. If subject develops retinal vasculitis 
and/or retinal vascular occlusion based on the investigator’s evaluation, the study treatment 
must be discontinued. In addition, as some of the subjects who experience IOI may be at risk 
of developing retinal vasculitis and/or retinal vascular occlusion, the subject should be closely 
monitored and managed according to clinical practice.
8.4.4
Other safety evaluations
8.4.5
Appropriateness of safety measurements
The safety assessments selected are standard for this indication/patient population. If there are 
any signs of IOI, additional assessment will be performed as described in Section 8.4.3.
8.5
Additional assessments
8.5.1
Clinical Outcome Assessments (COAs)
8.5.1.1
Patient Reported Outcomes (PRO)
The impact of brolucizumab on subject visual function will also be assessed by a visual function 
questionnaire using the National Eye Institute VFQ-25 which is a validated instrument that has 
been used in many studies of patients with nAMD. The VFQ-25 was developed to address the 
need to measure a patient’s subjective assessment of vision-related QoL (Mangione et al 2001). 
This is part of the 51-item NEI-VFQ which was developed based on feedback from patients to 
measure vision-targeted functioning and the impact of vision problems on HealthRelated 
Quality of Life (HRQL) across a number of common eye conditions. This allowed the 
developers to identify the content areas and aspects of visual disability that were most important 
and relevant to AMD patients.
At Baseline and Weeks 24 and EOS the VFQ-25 will be completed and captured by masked 
site staff on behalf of the subjects, at sites where local language versions are available, validated, 
and approved by the IEC/IRB. All these questionnaires should be completed before subjects see 
the study physician where applicable.

Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
A detailed training manual relating to the administrative procedures of the questionnaires will 
be provided to the sites.
Completed questionnaires will be reviewed and examined by the masked/evaluating 
investigator, before the clinical examination, for responses that may indicate potential AE or 
SAE. If AEs or SAEs are confirmed, then the physician must record the events as per 
instructions given in Section 10.1.1 and Section 10.1.2.
8.5.2
Pharmacokinetics
Systemic brolucizumab exposure will be assessed in approximately 24 consented subjects 
(approximately 12 subjects per treatment arm to maintain masking). Serum samples will be 
taken (according to manual provided by lab) at Day 1 prior to the first injection and at the 
following time points after the first injection: 6h post-injection on Day 1, Day 2, Day 8, Day 
15, Day 22, and Day 29 prior to the second injection.
Further details on sample collection, numbering, processing and shipment can be found in the 
central lab manual.
8.5.3
Other Assessments
Anti-drug antibodies (immunogenicity) 
Collection of blood for ADA assessment will be done at screening, Weeks 4, 12, 24, 36, 48 and 
exit/premature discontinuation in brolucizumab treatment arm (collection of ADA sample will 
be done in both treatment arms to maintain masking). Systemic exposure of brolucizumab will 
be measured concomitantly with ADA levels for interpretation purposes, no pharmacokinetic 
parameters will be determined from brolucizumab exposure measured at the above-mentioned 
timepoints (except, at visit 6 the blood drawn for anti-drug antibody in blood would also be 
used for PK analysis at the same visit, for the PK consent participants.). Additional 
pharmacodynamic assessment may be conducted on the samples wherever permitted by local 
regulation. Blood draws should take place prior to the injection/sham. A standardized 
procedure for the collection, processing, storage and shipment of these blood samples is 
provided by the central laboratory. Further details on sample collection, numbering, processing 
and shipment can be found in the central lab manual.

Study discontinuation and completion
9.1
Discontinuation
9.1.1
Discontinuation of study treatment
Discontinuation of study treatment for a subject occurs when study treatment is stopped earlier 
than the protocol planned duration, and can be initiated by either the subject or the investigator.
The investigator should discontinue study treatment for a given subject if, he/she believes that 
continuation would negatively impact the subject's well-being.
Study treatment must be discontinued under the following circumstances:

Subject/guardian decision


Novartis
Confidential
Page 53
Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307

Pregnancy 

Use of prohibited treatment as per recommendations in Table 6-2

Any situation in which study participation might result in a safety risk to the subject

Subject develops a retinal vasculitis and/or a retinal vascular occlusion event

Unsatisfactory therapeutic effect

Patient's condition no longer requiring study treatment
If discontinuation of study treatment occurs, the investigator should make a reasonable effort 
to understand the primary reason for the subject’s premature discontinuation of study treatment 
and record this information.
Subjects who discontinue study treatment should NOT be considered withdrawn from the study 
UNLESS they withdraw their consent (see withdraw of informed consent section,). The 
investigator must determine the primary reason for the patient’s premature discontinuation of 
study treatment and record this information on the appropriate eCRF page. Where possible, 
they should return for the assessments indicated in the assessment schedule. If they fail to 
return for these assessments for unknown reasons, every effort (e.g. telephone, e-mail, letter) 
should be made to contact the subject/pre-designated contact as specified in the lost to follow-
up section. This contact should preferably be done according to the study visit schedule.
If the subject cannot or is unwilling to attend any visit(s), the site staff should maintain regular 
telephone contact with the subject, or with a person pre-designated by the subject. This 
telephone contact should preferably be done according to the study visit schedule.
After study treatment discontinuation, at a minimum, in abbreviated visits, the following data 
should be collected at clinic visits or via telephone/email contact:

new / concomitant treatments

adverse events/Serious Adverse Events
The investigator must also contact the IRT to register the subject’s discontinuation from study 
treatment.
If discontinuation occurs because treatment code has been broken, please refer to Section 6.6.2.
9.1.2
Withdrawal of informed consent /Opposition to use data/biological 
samples
Subjects may voluntarily withdraw consent to participate in the study for any reason at any time. 
Withdrawal of consent/opposition to use data/biological samples occurs only when a subject:

Explicitly requests to stop use of their biological samples and/or data (opposition to use 
subject’s data and biological samples)
and
No longer wishes to receive study treatment and

Does not want any further visits or assessments (including further study-related contacts)
This request should be in writing (depending on local regulations) and recorded in the source 
documentation.


Novartis
Confidential
Page 54
Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
In this situation, the investigator should make a reasonable effort (e.g. telephone, e-mail, letter) 
to understand the primary reason for the subject’s decision to withdraw his/her consent and 
record this information.
Where consent to the use of Personal and Coded Data is not required in a certain country's legal 
framework, the participant therefore cannot withdraw consent. However, they still retain the 
right to object to the further collection or use of their Personal Data.
Study treatment must be discontinued and no further assessments conducted, and the data that 
would have been collected at subsequent visits will be considered missing.
Further attempts to contact the subject are not allowed unless safety findings require 
communicating or follow-up.
All efforts should be made to complete the assessments prior to study withdrawal. A final 
evaluation at the time of the subject’s study withdrawal should be made as detailed in the 
assessment table.
Discontinued subjects will not be replaced.
Novartis will continue to keep and use all research results (data) that have already been collected 
for the study evaluation, including processing of biological samples that has already started at 
time of consent withdrawal/opposition. No new Personal Data (including biological samples) 
will be collected following withdrawal of consent/opposition.
9.1.3
Lost to follow-up
For subjects whose status is unclear because they fail to appear for study visits without stating 
an intention to discontinue or withdraw, the investigator must show "due diligence" by 
documenting in the source documents steps taken to contact the subject, e.g. dates of telephone 
calls, registered letters, etc. A subject should not be considered as lost to follow-up until due 
diligence has been completed or until the end of the study.
9.1.4
Early study termination by the sponsor
The study can be terminated by Novartis at any time for any reason.
Reasons for early termination:

Unexpected, significant, or unacceptable safety risk to subjects enrolled in the study

Decision based on recommendations from applicable board(s) after review of safety and 
efficacy data

Discontinuation of study drug development
In taking the decision to terminate, Novartis will always consider the subject welfare and safety. 
Should early termination be necessary, subjects must be seen as soon as possible (provide 
instruction for contacting the subject, when the subject should stop taking drug, when the 
subject should come for a final visit) and treated as a prematurely withdrawn subject. The 
investigator may be informed of additional procedures to be followed in order to ensure that 
adequate consideration is given to the protection of the subject’s interests. The investigator or 
sponsor depending on the local regulation will be responsible for informing IRBs/IECs of the 
early termination of the trial.

9.2
Study completion and post-study treatment
Study completion is defined as when the last subject finishes their Study Completion visit (e.g. 
LPLV), and any repeat assessments associated with this visit have been documented and 
followed-up appropriately by the Investigator, or in the event of an early study termination 
decision, the date of that decision (e.g. Each subject will be required to complete the study in 
its entirety and thereafter no further study treatment will be made available to them).
10
Safety monitoring and reporting
10.1
Definition of adverse events and reporting requirements
10.1.1
Adverse events
An adverse event (AE) is any untoward medical occurrence (e.g., any unfavorable and 
unintended sign [including abnormal laboratory findings], symptom or disease) in a patient or 
clinical investigation patient 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.
The investigator has the responsibility for managing the safety of individual subject and 
identifying adverse events.
Novartis qualified medical personnel will be readily available to advise on trial related medical 
questions or problems.
The occurrence of adverse events must be sought by non-directive questioning of the subject at 
each visit during the study. Adverse events also may be detected when they are volunteered by 
the subject during or between visits or through physical examination findings, laboratory test 
findings, or other assessments.
Adverse events must be recorded in the Adverse Events CRF under the signs, symptoms or 
diagnosis associated with them, accompanied by the following information (as far as possible) 
(if the event is serious refer to Section 10.1.2):
1. The severity grade 

mild: usually transient in nature and generally not interfering with normal activities

moderate: sufficiently discomforting to interfere with normal activities

severe: prevents normal activities
2. its relationship to the study treatment. If the event is due to lack of efficacy or progression 
of underlying illness (i.e. progression of the study indication) the assessment of causality 
will usually be ‘Not suspected’. The rationale for this guidance is that the symptoms of a 
lack of efficacy or progression of underlying illness are not caused by the trial drug, they 
happen in spite of its administration and/or both lack of efficacy and progression of 
underlying disease can only be evaluated meaningfully by an analysis of cohorts, not on a 
single subject
3. its relationship to the study procedure
4. its duration (start and end dates) or if the event is ongoing, an outcome of not 
recovered/not resolved must be reported.


Novartis
Confidential
Page 56
Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
5. whether it constitutes a SAE (see Section 10.1.2 for definition of SAE) and which 
seriousness criteria have been met
6. action taken regarding study treatment.
All adverse events must be treated appropriately. Treatment may include one or more of the 
following:

Dose not changed

Drug interrupted/withdrawn
7. its outcome 
a. not recovered/not resolved;
b. recovered/resolved;
c. recovering/resolving,
d. recovered/resolved with sequelae;
e. fatal; or unknown.
Conditions that were already present at the time of informed consent should be recorded in 
medical history of the subject.
Adverse events (including lab abnormalities that constitute AEs) should be described using a 
diagnosis whenever possible, rather than individual underlying signs and symptoms.
Adverse event monitoring should be continued for at least 30 days following the last dose of 
study treatment.
Once an adverse event is detected, it must be followed until its resolution or until it is judged to 
be permanent (e.g. continuing at the end of the study), and assessment must be made at each 
visit (or more frequently, if necessary) of any changes in severity, the suspected relationship to 
the interventions required to treat it, and the outcome.
Information about adverse drug reactions for the investigational drug can be found in the 
Investigator Brochure (IB)
Abnormal laboratory values or test results constitute adverse events only if they fulfill at least 
one of the following criteria:

they induce clinical signs or symptoms

they are considered clinically significant

they require therapy
Clinically significant abnormal laboratory values or test results must be identified through a 
review of values outside of normal ranges/clinically notable ranges, significant changes from 
Baseline or the previous visit, or values which are considered to be non-typical in subjects with 
the underlying disease.
10.1.2
Serious adverse events
An SAE is defined as any adverse event [appearance of (or worsening of any pre-existing)] 
undesirable sign(s), symptom(s) or medical conditions(s)) which meets any one of the following 
criteria:

fatal

life-threatening


Novartis
Confidential
Page 57
Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
Life-threatening in the context of a SAE refers to a reaction in which the subject was at risk of 
death at the time of the reaction; it does not refer to a reaction that hypothetically might have 
caused death if it were more severe (please refer to the ICH-E2D Guidelines).

results in persistent or significant disability/incapacity

constitutes a congenital anomaly/birth defect

requires inpatient hospitalization or prolongation of existing hospitalization, unless 
hospitalization is for: 

routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition

elective or pre-planned treatment for a pre-existing condition that is unrelated to the 
indication under study and has not worsened since signing the informed consent

social reasons and respite care in the absence of any deterioration in the subject’s 
general condition

treatment on an emergency outpatient basis for an event not fulfilling any of the 
definitions of a SAE given above and not resulting in hospital admission

is medically significant, e.g. defined as an event that jeopardizes the subject or may 
require medical or surgical intervention to prevent one of the outcomes listed above
Medical and scientific judgment should be exercised in deciding whether other situations should 
be considered serious reactions, such as important medical events that might not be immediately 
life-threatening or result in death or hospitalization but might jeopardize the subject or might 
require intervention to prevent one of the other outcomes listed above. Such events should be 
considered as “medically significant”. Examples of such events are intensive treatment in an 
emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions that do 
not result in hospitalization. 
All malignant neoplasms will be assessed as serious under “medically significant” if other 
seriousness criteria are not met.
Any suspected transmission via a medicinal product of an infectious agent is also considered a 
serious adverse reaction.
10.1.3
SAE reporting
To ensure subject safety, every SAE, regardless of causality, occurring after the subject has 
provided informed consent and until 30 days after last study visit must be reported to 
Novartis/safety within 24-hours of learning of its occurrence.
1. SAEs occurring after the patient has provided informed consent until the time the patient 
is deemed a Screen Failure must be reported to Novartis/
All follow-up information for the SAE including information on complications, progression of 
the initial SAE and recurrent episodes must be reported as follow-up to the original episode 
within 24 hours of the investigator receiving the follow-up information. An SAE occurring at a 
different time interval or otherwise considered completely unrelated to a previously reported 
one must be reported separately as a new event.
If the SAE is not previously documented in the Investigator’s Brochure or Package Insert (new 
occurrence) and is thought to be related to the study treatment, a CMO&PS Department 
associate may urgently require further information from the investigator for health authority 


Novartis
Confidential
Page 58
Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
reporting. Novartis may need to issue an Investigator Notification (IN) to inform all 
investigators involved in any study with the same study treatment that this SAE has been 
reported.
Suspected Unexpected Serious Adverse Reactions (SUSARs) will be collected and reported to 
the competent authorities and relevant ethics committees (EC) in accordance with EU Guidance 
2011/C172/01 or as per national regulatory requirements in participating countries.
Any SAEs experienced after the 30 day period after the last study visit should only be reported 
to Novartis Safety if the investigator suspects a causal relationship to study treatment.
10.1.4
Pregnancy reporting
Pregnancies
If a female trial participant becomes pregnant, the study treatment should be stopped, and the 
trial participant must be asked to read and sign pregnancy consent form to allow the Study 
Doctor ask about her pregnancy.
To ensure subject safety, each pregnancy occurring after signing the informed consent must be 
reported to Novartis within 24 hours of learning of its occurrence. The pregnancy should be 
followed up to determine outcome, including spontaneous or voluntary termination, details of 
the birth, and the presence or absence of any birth defects, congenital abnormalities, or maternal 
and/or newborn complications.
Pregnancy must be recorded on the Pharmacovigilance Pregnancy Form and reported by the 
investigator to the local Novartis Drug Safety and Epidemiology Department. Pregnancy 
follow-up should be recorded on the same form and should include an assessment of the 
possible relationship to the study treatment.
Any SAE experienced during pregnancy must be reported.
Pregnancy outcomes should be collected for the female partners of any males who took study 
treatment in this study. Consent to report information regarding these pregnancy outcomes 
should be obtained from the mother.
10.1.5
Reporting of study treatment errors including misuse/abuse
Medication errors are unintentional errors in the prescribing, dispensing, administration or 
monitoring of a medicine while under the control of a healthcare professional, subject or 
consumer (EMA definition).
Misuse/ abuse is not applicable to this study as IVT injection is performed by the investigator.
Study treatment errors and uses outside of what is foreseen in the protocol will be recorded in 
the dose administration record (DAR) eCRF irrespective of whether or not associated with an 
AE/SAE and reported to Safety only if associated with an SAE.

Additional Safety Monitoring
10.2.1
Data Monitoring Committee
The RTH258 program level Data Monitoring Committee (DMC) will function independently 
of all other individuals associated with the conduct of this clinical trial, including the site 
investigators participating in the study. The DMC will assess at defined intervals the progress 
of a clinical trial, safety data, and critical efficacy variables and recommend to the sponsor 
whether to continue, modify or terminate a trial.
Specific details regarding composition, responsibilities, data monitoring and meeting frequency, 
and documentation of DMC reports, minutes, and recommendations will be described in a 
separate charter that is established between the sponsor and the DMC.
The DMC charter will include the DMC membership and responsibilities, the timing of DMC 
meetings, the content of the analysis report for the DMC meetings, and the communications 
with the Sponsor. The DMC will only make recommendations for changes in study conduct.
11
Data Collection and Database management
11.1
Data collection
Designated investigator staff will enter the data required by the protocol into the Electronic 
Case Report Forms (eCRF). The eCRFs have been built using fully validated secure web-
enabled software that conforms to 21 CFR Part 11 requirements, Investigator site staff will not 
be given access to the EDC system until they have been trained. Automatic validation programs 
check for data discrepancies in the eCRFs, allow modification and/or verification of the entered 
data by the investigator staff.
The investigator/designee is responsible for assuring that the data (entered into eCRF) is 
complete, accurate, and that entry and updates are performed in a timely manner. The 
Investigator must certify that the data entered are complete and accurate
After final database lock, the investigator will receive copies of the subject data for archiving 
at the investigational site.
All data should be recorded, handled and stored in a way that allows its accurate reporting, 
interpretation and verification.


Novartis
Confidential

Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
11.2
Database management and quality control
Novartis personnel (or designated CRO) will review the data entered by investigational staff 
for completeness and accuracy. Electronic data queries stating the nature of the problem and 
requesting clarification will be created for discrepancies and missing values and sent to the 
investigational site via the EDC system. Designated investigator site staff are required to 
respond promptly to queries and to make any necessary changes to the data.
Concomitant treatments and prior medications entered into the database will be coded using the 
WHO Drug Reference List, which employs the Anatomical Therapeutic Chemical classification 
system. Medical history/current medical conditions and adverse events will be coded using the 
Medical Dictionary for Regulatory Activities (MedDRA) terminology.
Randomization codes and data about all study treatment (s) dispensed to the subject and all 
dosage changes will be tracked using an Interactive Response Technology (IRT). The system 
will be supplied by a vendor, who will also manage the database. The data will be sent 
electronically to Novartis (or a designated CRO) at specific timelines.
Each occurrence of a code break via IRT will be reported to the clinical team and monitor. The 
code break functionality will remain available until study shut down or upon request of Novartis.
The occurrence of relevant protocol deviations will be determined. Once all the necessary 
actions have been completed and the database has been declared to be complete and accurate, 
it will be locked and the treatment codes will be unmasked and made available for data 
analysis/moved to restricted area to be accessed by independent programmer and statistician. 
Any changes to the database after that time can only be made after written agreement by 
Novartis development management.
11.3
Site monitoring
Before study initiation, at a site initiation visit or at an investigator’s meeting, a Novartis (or 
delegated CRO) representative will review the protocol and data capture requirements 
(i.e. eCRFs) with the investigators and their staff. During the study, Novartis employs several 
methods of ensuring protocol and GCP compliance and the quality/integrity of the sites’ data. 
The field monitor will visit the site to check the completeness of subject records, the accuracy 
of data capture / data entry, the adherence to the protocol and to Good Clinical Practice, the 
progress of enrollment, and to ensure that study treatment is being stored, dispensed, and 
accounted for according to specifications. Key study personnel must be available to assist the 
field monitor during these visits. Continuous remote monitoring of each site’s data may be 
performed by a centralized Novartis (or delegated CRO) CRA organization. Additionally, a
central analytics organization may analyze data & identify risks & trends for site operational 
parameters, and provide reports to Novartis clinical teams to assist with trial oversight.
The investigator must maintain source documents for each subject in the study, consisting of 
case and visit notes (hospital or clinic medical records) containing demographic and medical 
information, laboratory data, retinal imaging, and the results of any other tests or assessments. 
All information on CRFs must be traceable to these source documents in the subject’s file. The 
investigator must also keep the original informed consent form signed by the subject (a signed 
copy is given to the subject).


Novartis
Confidential
Page 61
Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
The investigator must give the monitor access to all relevant source documents to confirm their 
consistency with the data capture and/or data entry. Novartis monitoring standards require full 
verification for the presence of informed consent, adherence to the inclusion/exclusion criteria, 
documentation of SAEs, and of data that will be used for all primary variables. Additional 
checks of the consistency of the source data with the CRFs are performed according to the 
study-specific monitoring plan. No information in source documents about the identity of the 
subjects will be disclosed.
12
Data analysis and statistical methods
The primary efficacy and safety analysis will be based on data up to and including Week 48. 
This will be performed once all subjects complete the EOS visit or discontinue from the study. 
Summary statistics will be presented by treatment group unless otherwise specified. For 
continuous variables, summary statistics will generally include: n, mean, standard deviation, 
median, quartiles, minimum, and maximum. For categorical variables, these will generally 
include: n, frequency and percentage in each category. 
 
 
Further technical details and discussions of the statistical considerations will be provided in the 
SAP.
Any data analysis carried out independently by the investigator should be submitted to Novartis 
before publication or presentation.
12.1
Analysis sets
The Randomized Analysis Set (RAS) consists of all randomized patients. Patients are 
considered randomized when they had been deemed eligible for randomization by the 
investigator and given a randomization number. Subjects will be analyzed according to the 
treatment assigned to at randomization.
The Full Analysis Set (FAS) comprises all subjects to whom study treatment has been assigned 
by randomization and who receive at least one IVT injection of the study treatment. The full 
analysis set will serve as the primary analysis set for all efficacy analyses. According to the 
intent to treat principle, subjects will be analyzed according to the treatment they have been 
assigned to during the randomization procedure.
The Safety Set includes all subjects who received at least one dose of study treatment. Subjects 
will be analyzed according to the study treatment arm from which they received majority of 
treatments up to and including Week 44.
Supportive analyses of the primary and key secondary efficacy endpoints will include analysis 
using the Per-Protocol Set (PPS). PPS is a subset of the Full Analysis Set and will exclude 
subjects with protocol deviations (PDs) and analysis restrictions (ARs) that are expected to 
majorly affect the validity of the assessment of efficacy at Week 48 including for e.g. lack of 
compliance (including missed treatments and treatment misallocation), missing data, prohibited 
concomitant medication and deviation from inclusion/exclusion criteria. Confounded data or

discontinuation from treatment due to lack of efficacy and/or safety do not constitute a reason 
for exclusion from the PPS.
Before the database lock, the relevant protocol deviations will be identified at the subject level 
in the database. After the database lock, analysis restrictions will be derived in the analysis 
database. Censoring applied in relation to the specific PDs / ARs will be specified as well.
The FAS will be the analysis set for the primary estimand as defined in Table 12-1. However, 
when assessing the robustness of the overall efficacy conclusions, considerations will be given 
to the analysis based on the primary estimand using FAS and the supplementary estimand (see 
Table 12-1) using PPS, i.e., similar conclusions on non-inferiority based on both estimands are 
expected. Inconsistencies in key efficacy study results between the FAS and PPS will be 
examined and discussed in the clinical study report (CSR).
The Pharmacokinetic analysis set includes all subjects who provide an evaluable PK profile for 
brolucizumab. A profile is considered evaluable if all of the following conditions are satisfied:

Subject receives the planned first dose of brolucizumab

Subject provides at least one primary PK parameter of brolucizumab (Cmax and AUC)
12.2
Subject demographics and other baseline characteristics
Demographic and Baseline characteristics will be summarized for all analysis sets. All 
summaries will be presented by the treatment group and overall.
The demographic parameters are age category (50 to 64, 65 to 74, 75 to 84, and ≥ 85), gender 
and race. Age will also be summarized as a continuous variable.
Baseline characteristics will include: primary diagnosis of neovascular AMD, time since 
diagnosis of neovascular AMD (days), whether neovascular AMD is unilateral or bilateral, 
BCVA (both as a continuous variable and as a categorical variable (≤ 55, ≥56-≤70, ≥ 71 letters)), 
lesion type (predominantly classic, minimally classic, pure occult), foveal involvement 
(subfoveal, extrafoveal, undeterminable), CNV lesion size, presence of subretinal fluid, 
presence of intraretinal fluid/cyst, presence of sub RPE fluid, neurosensory retinal thickness, 
CSFT (both as a continuous variable and as a categorical variable (< 400 ≥ 400 μm)).
12.3
Treatments
The Safety set will be used for the analyses below.
The extent of treatment exposure will be presented based on the overall number of injections, 
the number of subjects injected per visit, and frequency of the different treatment patterns.
Relevant medical history (ocular and non-ocular) will be tabulated by system organ class and 
preferred term of the MedDRA dictionary. Ocular events will be presented by study and non-
study eye.
The number and percentage of subjects taking concomitant therapies will be summarized by 
preferred term according to the WHO Drug Reference List dictionary. Ocular therapies will be 
presented by study and non-study eye.

Analysis of the primary endpoint(s)
12.4.1
Definition of primary endpoint(s)
The primary endpoint is the change from Baseline in BCVA at Week 48. The first key 
secondary endpoint is average change in BCVA from Baseline over the period Week 36 through 
Week 48. For each subject, this endpoint is defined as the average of the changes from Baseline 
to Week 36, 40, 44 and 48. The primary analysis of the primary and first key secondary 
endpoints will be based on the FAS.
12.4.2
Statistical model, hypothesis, and method of analysis
The statistical hypothesis for the primary endpoint and first key secondary endpoint is non-
inferiority of brolucizumab 6 mg to aflibercept 2 mg within a margin of 4 letters.
The following 2 hypotheses will be tested in the pre-specified hierarchical sequence according 
to their numbering (HAn, n=1,2). Consequently, confirmatory testing of the second hypothesis 
requires rejection of the first null hypothesis. In this setting, each hypothesis will be assessed at 
a one-sided significance level of 0.05, while keeping the global type I error rate at 0.05.
Hypotheses: The following noninferiority hypotheses are related to a noninferiority margin of 
4 letters.
48 = Week 48, 36-48 = Week 36 through 48, R= brolucizumab 6 mg, A= aflibercept 2 mg
H01: μ48R - μ48A ≤ -4 letters vs HA1: μ48R - μ48A > -4 letters
μ48R and μ48A being the corresponding unknown true mean BCVA changes from Baseline to 
Week 48.
H02: μ36-48R - μ36-48A ≤ -4 letters vs HA2: μ36-48R - μ36-48A > -4 letters
μ36-48R and μ36-48A being the corresponding unknown true mean values for the average change 
in BCVA from Baseline over the period Week 36 through 48.
For the test of non-inferiority, a two-sided 90% CI for the treatment difference will be derived 
from an analysis of variance (ANOVA) model with treatment, Baseline BCVA categories (≤55, 
≥56-≤70, ≥ 71 letters) and age categories (< 75, ≥ 75 years) as factors. In order to demonstrate 
non-inferiority, the lower limit of the two-sided 90% CI for the treatment difference 
(brolucizumab 6 mg – aflibercept 2 mg) must be greater than -4 letters representing the 
noninferiority margin. 
The primary estimand and supplementary estimand of interest are described in Table 12-1
below, together with their key attributes, and will be discussed in further detail in the SAP.

Handling of missing values/censoring/discontinuations
Missing BCVA values will be imputed by LOCF (Last Observation Carried Forward) as a 
primary approach. For subjects with no post-Baseline BCVA value, the Baseline value will be 
carried forward. Data collected after start of alternative nAMD treatment in the study eye (e.g. 
other anti-VEGF treatment, as further detailed in the SAP) will be censored for the primary 
analysis. All non-missing post-Baseline values including assessments done at unscheduled 
visits will be used when implementing the LOCF imputation. From an estimand perspective, 
the main focus is to adequately reflect in the analysis unfavorable study outcome related to the 
treatment (e.g. lack of efficacy, safety problems).
The LOCF approach is expected to be sensitive to an early study termination due to lack of 
efficacy assuming that such lack of efficacy is reflected in the last observed BCVA 
measurement. In case of the use of alternative treatment for the underlying disease, data 
collected after the start of such a treatment would be censored. LOCF will then be based on the 
last value prior to the start of this treatment, again expecting that this value would reflect the 
negative BCVA outcome under study treatment. In case of missing data due to lack of 
safety/tolerability with impairment of the function of the study eye the LOCF method would 
also provide a sensitive approach to capture such an unfavorable outcome.
In case of missing data occurring independently of the response to study treatment, the LOCF 
approach assumes stability which seems to be adequate based on historical data both for the 
maintenance treatment phase (i.e. stabilization of BCVA) and also in case of the absence of any 
treatment effect. In case of an early study termination during the loading phase, the LOCF 
method will result in a conservative estimate potentially underestimating the true outcome. 
LOCF is an established method within the assessment of efficacy of anti-VEGF treatments in 
terms of BCVA outcome. It is important to note that non-inferiority studies should follow the 
main design features (primary variables, the dose of the active comparator, eligibility criteria, 


Novartis

etc.) as the previously conducted superiority trials in which the active comparator demonstrated 
clinically relevant efficacy. 
Other methods of handling missing or confounded data within sensitivity analyses will be 
performed, as detailed in the SAP.
12.4.4
Sensitivity and Supportive analyses
Sensitivity and supportive analysis to explore the robustness of the primary efficacy results with 
respect to protocol deviations will use the PPS with LOCF imputation of missing values using 
the same model and factors as in the primary efficacy analysis model.
Sensitivity analyses to explore the robustness of the primary and first key secondary efficacy 
analysis results related to missing values will be performed on the observed data in the FAS 
applying the specified ANOVA model and a mixed model repeated measures (MMRM) 
assuming missing at random.
The following subgroups will be analyzed for the primary and first key secondary efficacy 
endpoints using the primary analysis approach:

Age category (< 75 years and ≥75 years)

Gender (male and female) 

Baseline BCVA categories (≤ 55, ≥56-≤70, ≥ 71 letters)

Baseline CSFT category (< 400, ≥ 400)

Baseline lesion type (predominantly classic, minimally classic, pure occult)
12.5
Analysis of secondary endpoints
12.5.1
Efficacy and/or Pharmacodynamic endpoint(s)
Secondary endpoints will be analyzed based on FAS.
Key secondary efficacy endpoints related to dosing regimen:

q12w treatment status at Week 48 for subjects randomized to brolucizumab 6 mg

q12w treatment status at Week 48 within the subjects randomized to brolucizumab 6 mg 
and with no q8w need during the first q12w cycle (Week 16 and Week 20)
The key secondary endpoints will be analyzed based on the FAS with a negative q12 treatment 
status at Week 48 in case of incomplete active treatment up to Week 48.
The q12w treatment status at Week 48 in brolucizumab 6 mg treatment arm will be presented 
descriptively together with exact 90% confidence intervals for the proportion of subjects with 
a positive status: For the (overall) proportion of subjects with a positive q12w treatment status 
at Week 48, the denominator is all FAS subjects in the brolucizumab 6 mg group, and the 
numerator is the corresponding number of subjects with no identified q8w-need at Week 16, 20, 
32 and 44 (while missing the Week 16 assessment is considered as no q8w treatment needed). 
For the predictability of the adequacy of q12w treatment based on the absence of disease activity 
during the first q12w cycle, the denominator is all FAS subjects in the brolucizumab 6 mg group 
with no identified q8w-need at Week 16 and Week 20 (while missing the Week 16 assessment 
is considered a no-q8w treatment needed), and the numerator is the corresponding number of 


Novartis

Amended Protocol Version 04 (Clean)
Protocol No. CRTH258A2307
subjects with a positive q12w treatment status at Week 48 (i.e. with no identified q8w-need at 
Week 16, 20, 32 and 44).
Secondary efficacy endpoints based on BCVA:

Change in BCVA from Baseline to each post-Baseline visit

Average change in BCVA from Baseline over the period Week 4 to Week 48

Average change in BCVA from Baseline over the period Week 12 to Week 48

Gain in BCVA of 15/10/5 letters or more from Baseline to each post-Baseline visit
Note: Subjects with BCVA value of 84 letters or more at a post-Baseline visit will be considered 
as responders for the corresponding endpoint. This is to account for a ceiling effect, e.g. for the’ 
≥15-letter gain’ endpoint, for those subjects with BCVA values at Baseline ≥ 70 letters.

Absolute BCVA of 73 letters or more at each visit

Loss in BCVA of 15/10/5 letters or more from Baseline to each post-Baseline visit 
Secondary efficacy endpoints related to anatomy or disease activity:

Change in CSFTtot from Baseline to each post-Baseline visit

Average change in CSFTtot from Baseline over the period Week 36 through Week 48

Average change in CSFTtot from Baseline over the period Week 4 to Week 48

Change in CSFTns from Baseline to each post-Baseline visit

Change in area of CNV within the lesion from Baseline to Weeks 12 and 48

Presence of subretinal and/or intraretinal fluid (central subfield) at each post-Baseline visit 
(and specifically Week 16 and Week 48)

Number of visits with simultaneous absence of subretinal and intraretinal fluid (central 
subfield) during Week 36 to Week 48

Presence of subretinal fluid (central subfield) at each post-Baseline visit

Presence of intraretinal fluid (central subfield) at each post-Baseline visit

Presence of sub RPE fluid (central subfield) at each post-Baseline visit
Secondary efficacy endpoints related to efficacy at the end of the matched treatment phase:

Change in CSFTtot from Baseline at Week 16

Presence of subretinal and/or intraretinal fluid (central subfield) at Week 16

q8w treatment need identified at Week 16

assessed for the injection procedure and the drug). Serious adverse events and adverse events 
leading to discontinuation of study treatment will also be summarized separately.
Subject listings of all adverse events will be provided. Deaths and other serious or clinically 
significant non-fatal adverse events will be listed separately.
An adverse event of special interest (ESI) is one of scientific and medical interest to the Sponsor 
and include, but is not limited to, the following:


Uveitis: all cases of anterior, posterior, or panuveitis

≥30 letter decrease in BCVA compared with Baseline visual acuity

New retinal tear or detachment

New diagnosis of geographic atrophy
The number (and proportion) of subjects with adverse events related to identified and potential 
risks, including AEs of special interest will be summarized by treatment
Ophthalmic examinations
Pre-injection IOP measurements will be presented descriptively (absolute values and change 
from Baseline). Post-injection IOP measurements will be listed. Presence of fibrosis from color 
fundus photography by assessment visit will be summarized.
Laboratory tests, vital signs, and special tests
Laboratory data and vital signs will be summarized by presenting shift tables using extended 
normal ranges (as provided by the central laboratory) with thresholds representing clinical 
relevant abnormality and by presenting descriptive statistics of raw data and change from 
Baseline. Values outside the extended normal range will be listed by subject and treatment arm 
and flagged in data listings.
12.5.3
Pharmacokinetics
Pharmacokinetic parameters will be determined using Phoenix WinNonlin (Version 6.4 or later-
Certara L.P) using non-compartmental method(s) for the subjects who had full PK sampling (7 
blood sampling points after first dose). PK parameters will be listed by treatment and subject. 
Descriptive summary statistics will include mean (arithmetic and geometric), SD, and CV 
(arithmetic and geometric), median, minimum and maximum. An exception to this is Tmax 
where median, minimum and maximum will be presented. For calculation of PK parameter, 
Concentrations below LLOQ will be treated as missing.
Serum concentrations will be summarized by treatment and time point for the subjects who had 
full PK sampling following first dose. Summary statistics will include n (number of values to 
be reported), arithmetic and geometric mean, median, SD, CV, and geometric CV, minimum 
and maximum. For the purpose of calculating descriptive statistics for serum concentrations, 
post-injection concentrations below the LLOQ will be treated half of LLOQ in summary 
statistics. If the mean was less than the LLOQ, it was reported as being BLQ within the summary 
tables.

Sample size calculation
12.8.1
Primary endpoint(s)
In the spirit of bridging concept under ICH E5, a sample size of 175 subjects per treatment arm 
is sufficient to demonstrate noninferiority (margin = 4 letters) of brolucizumab 6 mg versus 
aflibercept 2 mg with respect to the BCVA change from Baseline to Week 48 at a one-sided 
alpha level of 0.05 with a power of approximately 80% assuming equal efficacy and a common 
standard deviation of 15 letters. A power of at least 80% can be expected for the first key 
secondary endpoint assuming that averaging BCVA change from Baseline over the 4 time 
points will not lead to an increase in the standard deviation. To account for a drop-out rate of 
10%, a total of 195 subjects will be randomized per treatment arm.

Introduction 
The purpose of this Statistical Analysis Plan (SAP) is to describe the implementation of 
statistical analysis planned in the study protocol, and to provide detailed statistical methods that 
will be used for the Clinical Study Report (CSR) of study CRTH258A2307. 
Data will be analyzed according to the data analysis Section 12 of the study protocol (Clinical 
Trial Protocol CRTH258A2307 v04 dated 14-Jun-2022) which will be available in Appendix 
16.1.1 of the CSR. Important information is given in the following sections and details will be 
provided, as applicable, in Appendix 16.1.9 of the CSR. 
The SAP will be finalized before treatment unmasking. Any changes to the SAP after approval 
will be documented in CREDI. 
1.1 
Study design 
This is a randomized, double-masked, multicenter, parallel-group, active-controlled study. The 
study includes 14 scheduled visits over 48 weeks. A screening period of 2 weeks will be used 
to assess eligibility. 
After confirmation of eligibility at baseline, approximately 390 subjects will be randomized in 
a 1:1 ratio to one of the two treatment arms (approximately 195 subjects per arm): 
• Brolucizumab 6 mg: three monthly intravitreal injections of brolucizumab 6 mg during the 
loading treatment period (q4w regimen) up to Week 8 followed by injections every 12 
weeks (q12w regimen) or 8 weeks (q8w regimen) up to Week 40 or Week 44, depending 
on the status of disease activity. 
• Aflibercept 2 mg: three monthly intravitreal injections of aflibercept 2 mg during the 
loading treatment period (q4w regimen) up to Week 8 followed by injections every 8 weeks 
(q8w regimen) up to Week 40. 
Only one eye fulfilling all eligibility criteria will be selected/ treated and will be defined as the 
study eye. 
Novartis Interactive Response Technology will be used for randomization.  
There are no stratification factors in this study. 
There are no interim analyses in this study.

Objective(s) 
Endpoint(s) 
┼ Change in BCVA from Baseline to Week 48 in the study eye is the primary endpoint, corresponding to the 
primary objective, which is consistent with pivotal studies (HAWK & HARRIER). 
# Average change in BCVA from Baseline over the period Week 36 to Week 48 in the study eye is the first key 
secondary endpoint, considered also of clinical importance and therefore corresponds to the primary objective 
of the study.

Statistical methods 
2.1 
Data analysis general information 
The primary analysis will be performed after all subjects completed or discontinued the study 
by Novartis using SAS 9.4 or above.  
Continuous variables will be summarized using the number of observations, mean, standard 
deviation, standard errors (SE), median, quartiles, minimum and maximum values. Categorical 
variables will be summarized with number of observations, the number of observations for each 
category and the corresponding percent. Where appropriate, 2-sided 90% confidence intervals 
(CIs) for point estimates of the mean or proportion will be provided. For the treatment difference 
brolucizumab – aflibercept, point estimates with 90% CIs will be provided as appropriate unless 
otherwise specified. 
 
 
2.1.1 
General definitions  
Study drug and study treatment 
Study drug refers to both Brolucizumab 6 mg and Aflibercept 2 mg via intravitreal (IVT) 
injections. 
Study treatment refers to study drug or sham injections. 
Study day 
Day 1 is defined as the date of the first study treatment.  Study day is defined as the number of 
days since the date of first dose of study treatment (Day 1). 
Therefore, for a particular date, study day will be calculated as follows: 
• for dates on or after the date of first administration of study treatment: 
Study day = Assessment date – Date of first study treatment + 1; 


Novartis 
For business use only 
Page 13 of 45 
SAP 
 
CRTH258A2307 
 
• for dates prior to the date of first administration of study treatment: 
Study day = Assessment date – Date of first study treatment. 
 
Baseline 
The baseline value is defined as the last assessment performed prior to administration of the 
first dose of study treatment.  
All data collected after the first study treatment are defined as post-baseline. 
End of study day mapping 
The end of the study day is the date when a subject completes or discontinues the study. 
For reporting data by visit in outputs, the end of study visit will be allocated to the actual 
(reported) visit number. If the end of study date is not on a scheduled visit, then the end of study 
visit will be allocated, based on study day, to the closest future scheduled study visit. 
Unscheduled visits 
Data collected at unscheduled visits will not be used in ‘by-visit’ tabulations or graphs but will 
be included in analyses based on all postbaseline values such as last observation carried forward 
(LOCF) imputation, and summary of maximum letter loss in BCVA from baseline. Only values 
at scheduled visits (observed or imputed by LOCF) will be considered to average BCVA change 
from baseline over a given period. These data will not be used in analyses with mixed model 
for repeated measures (MMRM). 
Moreover, given unscheduled visits will not be active treatment visits, IOP measurements at 
unscheduled visits will not be considered as pre-injection IOP measurements, hence will not be 
used to identify subjects with pre-injection IOP >30 mmHg. 
Missing and implausible dates 
The general approach to handling missing dates is shown in Section 5.1. 
2.2 
Analysis sets 
The All Enrolled Set includes all subjects who signed informed consent and are assigned with 
subject numbers. This analysis set will be used to summarize subject disposition. 
The Randomized Set (RAN) will consist of all randomized subjects. Subjects are considered 
randomized when they have been deemed eligible for randomization by the investigator and 
given a randomization number. Subjects will be analyzed according to the treatment assigned 
to at randomization. 
The Full Analysis Set (FAS) includes all randomized subjects who receive at least one IVT 
injection of the study treatment. The full analysis set will serve as the primary analysis set for 
all efficacy analyses. Following the intent-to-treat principle, subjects will be analyzed according 
to the treatment assigned to at randomization. 
Supportive analyses of the primary and key secondary endpoints will include analysis using the 
Per Protocol Set (PPS). PPS is a subset of the FAS and will exclude subjects with important 
protocol deviations (PDs) and analysis restrictions (ARs, i.e. non-protocol deviations) that are

expected to majorly affect the validity of the assessment of efficacy and/or safety at the end of 
study. Confounded data or discontinuation from treatment due to lack of efficacy and/or safety 
do not constitute a reason for exclusion from the PPS.  
PDs that may lead to exclusion from PPS are specified in Table 5-3. ARs that may lead to 
exclusion from PPS are specified in Table 5-4. Before the database locks, the relevant protocol 
deviations will be identified at the subject level in the database. After the database locks, 
analysis restrictions will be derived in the analysis database. Subject evaluability based on pre-
specified PDs and/or ARs and their impact on analysis sets will be determined prior to the 
database lock. Censoring applied in relation to the specific PDs/ARs will be specified as well. 
Details are specified in Section 5.5 and Section 5.6. 
The FAS will be the analysis set for the primary estimand as defined in  Table 2-1. However, 
when assessing the robustness of the overall efficacy conclusions, considerations will be given 
to the analysis based on the primary estimand using FAS and the supplementary estimand (see 
Table 2-1) using PPS. Inconsistencies in key efficacy study results between the FAS and PPS 
will be examined and discussed in the clinical study report (CSR). 
The Safety Analysis Set (SAF) will include all subjects who receive at least one study drug 
IVT injection. Subjects in the safety analysis set will be analyzed according to the treatment 
arm from which they received the majority of treatments. 
2.2.1 
Subgroup of interest 
The subgroups of interest are specified below: 
• Age category (< 75 years and ≥ 75 years)

Subgroup analysis will be performed on FAS for the primary and first key secondary efficacy 
endpoints, (as defined in Section 2.5.1), using the primary analysis approach. More details can 
be found in Section 2.5.4.

alternative nAMD treatment in the study eye will be censored (from the day the subject started 
alternative nAMD treatment onwards). 
A listing of subjects who received alternative nAMD treatment in the study eye will be provided. 
2.5 
Analysis of the primary objective 
2.5.1 
Primary endpoint and first key secondary endpoint 
• The primary efficacy endpoint is change in BCVA from baseline to Week 48 in the study 
eye. 
• The first key secondary endpoint is average change in BCVA from baseline over the period 
Week 36 through Week 48 in the study eye. For each subject, this endpoint is defined as the 
average of the changes from baseline to Weeks 36, 40, 44 and 48.

CRTH258A2307 
 
The primary efficacy analyses of these two endpoints will be based on the FAS with LOCF 
imputation or replacement of missing or censored BCVA values. 
The primary estimand for the primary endpoint includes the following components: 
• Population: Chinese subjects with neovascular age-related macular degeneration as per the 
inclusion/exclusion criteria. 
• Endpoint: The primary endpoint is the change from baseline in BCVA at Week 48. BCVA 
will be assessed by the masked assessor using ETDRS-like charts at an initial distance of 4 
meters. 
• Treatment of interest: brolucizumab or aflibercept 
• The handling of the intercurrent events as follows: 
o 
Treatment discontinuation due to any reason: use the observed data, or impute using 
LOCF if missing 
o 
Data after the start of alternative nAMD treatment will be censored and replaced 
using LOCF 
• Summary measure: Difference in the change from baseline in BCVA at Week 48 between 
brolucizumab and aflibercept treatment arms. 
2.5.2 
Statistical hypothesis, model, and method of analysis  
The objective related to the primary and first key secondary endpoints is to demonstrate non-
inferiority of brolucizumab to aflibercept with respect to change from baseline in BCVA, 
considering a margin of 4 letters. 
Let:  
B = Brolucizumab 6 mg 
- 3 x q4w loading then q12w/q8w maintenance 
A = Aflibercept 2 mg    
- 3 x q4w loading then q8w maintenance 
The following non-inferiority hypotheses are related to a non-inferiority margin of 4 letters:  
 
H01: μB – μA 
≤ -4 letters 
vs. 
HA1: μB – μA 
> -4 letters 
 
H02: B – A 
≤ -4 letters 
vs. 
HA2: B – A 
> -4 letters 
where μB and μA are the corresponding unknown true mean changes from baseline in BCVA at 
Week 48; B and A are the corresponding unknown true mean changes from baseline in BCVA 
averaged over the period Week 36 to Week 48. 
Based on the FAS, the above hypotheses will be tested via an analysis of variance (ANOVA) 
model. The model will include treatment, baseline BCVA (≤ 55, ≥56-≤70, ≥ 71 letters) and age 
category (<75, ≥75 years) as factors. Two-sided 90% confidence interval (CI) for the least 
square means (LSM) difference (brolucizumab - aflibercept) will be presented. Non-inferiority 
will be considered established if the lower limit of the corresponding 90% CI is greater than -4 
letters. P-value for non-inferiority (4-letter margin) (1-sided) will be presented. 
The two hypotheses will be tested sequentially (HAn, n=1, 2), i.e. confirmatory testing of the 
second hypothesis requires rejection of the first null hypothesis.

In this setting, each hypothesis will be assessed at a one-sided significance level of 0.05, while 
keeping the global type I error rate at 0.05. 
The primary estimand and other supplementary estimands of interest are described in Table 2-
1 below, together with their key attributes. The same approach for non-inferiority assessment 
in change from baseline in BCVA at Week 48 and average change from baseline in BCVA over 
the period Week 36 through Week 48 will be applied to supplementary estimands.

2.5.3 
Handling of missing values/censoring/discontinuations 
Missing BCVA values will be imputed using LOCF as a primary approach. Observed values 
from both scheduled and unscheduled visits will be used for the LOCF imputation. For subjects 
with no postbaseline BCVA value, the baseline value will be carried forward.  
LOCF is an established method within the assessment of efficacy of anti-VEGF treatments in 
terms of BCVA outcome. In case of missing data occurring independently of the response to 
study treatment, the LOCF approach assumes stability which seems to be adequate based on the 
nature of the disease progression and historical data. In case of missing data due to lack of 
efficacy or safety/tolerability with impairment of the function of the study eye, the LOCF 
method would be able to capture such an unfavorable outcomes as reflected in the last observed 
measurement. 
For subjects who discontinue treatment but continue in the study, data collected after switching 
to the alternative nAMD treatment in the study eye (see Table 2-2) will be censored for the 
primary analysis. Censored or missing data will be replaced or imputed using LOCF by the last 
observation collected prior to the start of alternative nAMD treatment in the study eye. Detailed 
alternative nAMD treatments will be listed in the Programming Data Specifications (PDS) 
documentation. If there are newly approved nAMD treaments, they will be reflected in the PDS.

• 
Faricimab 
•

Intraocularly/periocularly administered steroids: 
o 
Dexamethasone 
o 
Fluocinolone acetonide 
o 
Triamcinolone acetonide 
o 
Other intraocular/periocular steroids 
From the estimand perspective, the main purpose is to adequately reflect the unfavorable study 
outcome related to the treatment (e.g. lack of efficacy, safety problems) in the analysis.  
2.5.4 
Sensitivity and supportive analyses 
2.5.4.1 
Sensitivity analyses on the primary estimand 
Sensitivity to the statistical model and imputation assumptions from the primary estimand will 
be considered, using FAS only. 
An alternative method of handling missing values such as below will be considered to assess 
the robustness of the hypothesis testing in comparison to the results from the primary analysis: 
• Mixed model for repeated measures (MMRM) assuming missing at random (MAR) using 
observed data only. The MMRM will include treatment, visit, baseline BCVA category, age 
category and treatment by visit interaction as fixed effect terms and visit as a repeated 
measure. An unstructured covariance matrix will be used to model the within-patient error. 
For the MMRM analysis: 
• The treatment difference brolucizumab - aflibercept at Week 48 will be estimated using 
the LSM and 90% CI. 
• If an MMRM model with an unstructured covariance matrix does not converge, a more 
restricted covariance matrix can be considered in the following order until convergence 
is reached: Toeplitz (TOEP), first-order autoregressive (AR), compound symmetry 
(CS), and variance components (VC). 
In this analysis, data collected after the switch to alternative nAMD treatment in the study eye 
will be censored. 
For the endpoint of average change from baseline over the period Week 36 through Week 48, 
a SAS code using the ESTIMATE statement in PROC MIXED will be provided in the 
programming specification document to obtain the LSM estimate and 90% CI for the 
corresponding treatment difference. P-value for non-inferiority (1-sided) will be presented.

Other sensitivity analyses on the primary estimand might be considered. 
2.5.4.2 
Supportive analyses using different supplementary estimands 
Supplementary estimand 1 on the PPS: 
The target population, the primary endpoint, the treatment of interest and the summary measure 
of the supplementary estimand 1 are the same as for the primary estimand. Different from the 
primary estimand, the handling of the intercurrent events for the supplementary estimand 1 can 
be found in Table 5-6 for the PPS population. The supportive analysis on the supplementary 
estimand 1 will apply the same LOCF/ANOVA method as for the primary estimand.

2.5.4.3 
Summary statistics and subgroup analysis 
Summary statistics: 
• Descriptive statistics of primary and first key secondary endpoints will use observed 
data and primary analysis set (FAS), with censoring data after use of alternative nAMD 
treatment in the study eye. 
Subgroup analyses will be conducted to assess the consistency of treatment effect across 
various subgroups described in Section 2.2.1. They will be conducted using the framework for 
the primary estimand only (FAS with censoring of data collected after use of alternative nAMD 
treatment in the study eye, and missing/censored values imputed/replaced using LOCF). 
• Subgroup analyses will be conducted using the same model and analysis strategies 
described for the primary and  first key secondary endpoint but fitted by category of 
each of the subgroups. Subgroup variables that are used as fixed effects in the model 
will be removed from the model statement for the subgroup analysis. 
• In case of analyses on subgroups with extremely imbalanced sample sizes, the subgroup 
levels can either be combined, if appropriate, or the extremely small subgroup will be 
excluded while fitting the analysis model. 
• The point estimate and 90% CI for the between treatment difference for each subgroup 
will be presented using forest plots. 
2.6 
Analysis of additional key secondary objectives 
2.6.1 
Additional key secondary endpoints 
Additional key secondary efficacy endpoints related to dosing regimen: 
• q12w treatment status at Week 48 for subjects randomized to brolucizumab 6 mg 
• q12w treatment status at Week 48 within the subjects randomized to brolucizumab 6 mg 
and with no q8w need during the first q12w cycle (Week 16 and Week 20) 
2.6.2 
Statistical hypothesis, model, and method of analysis 
No hypothesis will be tested for additional key secondary efficacy endpoints. The additional 
key secondary efficacy endpoints will be analyzed based on FAS in brolucizumab 6 mg group. 
The analysis approach described below (efficacy/safety approach) will be conducted. 
The estimate for the proportion of subjects with a positive q12w treatment status will be derived 
from Kaplan-Meier (KM) time-to-event analyses for the event ‘first q8w-need’, applying a 
‘q8w-need’ allocation in case of missing or confounded data attributable to lack of efficacy 
and/or lack of safety for the purpose of analysis. 
The proportion of subjects with a positive q12w treatment status will be derived as follows 
according to the ‘sufficient efficacy and safety’ approach: 


Novartis 
For business use only 
Page 24 of 45 
SAP 
 
CRTH258A2307 
 
• The q8w-need assessment is imputed as “Yes” at the DAA visit following early 
treatment/study discontinuation due to lack of efficacy and/or lack of safety of the study 
treatment (applies to both missing and non-missing DAAs). 
Intercurrent events associated with missing or confounded data regarding the q12w treatment 
status that are attributable to reasons other than lack of efficacy and/or safety are described 
below, together with the corresponding data handling strategies: 
• Early treatment/study discontinuation: censoring at the last valid DAA visit while on 
treatment/study 
• Single missed visit with a relevant DAA: censoring at the last valid DAA prior to the missed 
visit 
• Prohibited concomitant medications/procedures: censoring at the last valid DAA prior to 
the corresponding application 
• Discrepancy between DAA by investigator and the actual treatment received: censoring at 
the corresponding visit 
• Other treatment allocations/applications deviating from the concept of ‘treatment allocation 
according to disease activity’: censoring at the last valid DAA at or prior to the deviating 
visit. 
Censoring rules related to the q12w treatment status analysis are described in Section 5.6. 
The proportion of subjects with a positive q12w treatment status at Week 48 will be presented 
together with two-sided 90% confidence intervals. 
The outcome of the Kaplan-Meier analysis will be presented graphically by the estimated q12w-
probability over time, i.e. at each DAA visit. 
The analysis of ‘q12w treatment status at Week 48 within the subjects randomized to 
brolucizumab 6 mg and with no q8w need during the first q12w cycle’ is based on the subset of 
FAS subjects randomized to brolucizumabe 6 mg with no identified q8w-need at Week 16 and 
Week 20. For this subset a valid Week 20 DAA is required while missing the Week 16 DAA is 
considered as no q8w-need. 
2.6.3 
Handling of missing values/censoring/discontinuations 
The details regarding handling of missing values and discontinuations, including the timing of 
censoring within the time-to-event analyses for the event ‘first q8w-need’, are specified in the 
previous Section 2.6.2.  
Subjects without any valid DAA are considered censored at baseline for the overall q12w 
proportion and for the analysis of the predictive value of the first q12w cycle. 
From the estimand perspective, the impact of failing study completion according to the protocol 
due to lack of efficacy/safety is considered adequately reflected by a negative q12w-status.  
2.6.4 
Supportive analyses 
Supportive analyses will be performed on the FAS using alternative methods of handling 
missing or confounded data: 


Novartis 
For business use only 
Page 25 of 45 
SAP 
 
CRTH258A2307 
 
• ‘Efficacy only’ approach: approach with ‘q8w-need’ allocation only in case the reason 
for a missing or confounded q12w status is attributable to lack of efficacy of the study 
treatment. In case of a corresponding safety reason the subject is censored at the last 
valid DAA.  
Additionally, analyses described in Section 2.6.2 conducted using the FAS will be repeated 
using the PPS to assess the consistency of the assessment of the q12w proportions when looking 
only at those subjects who adhere to the protocol. 
2.7 
Analysis of secondary efficacy objectives 
2.7.1 
Secondary endpoints 
Secondary efficacy endpoints are listed below. 
Secondary efficacy endpoints based on BCVA: 
• Change in BCVA from Baseline to each postbaseline visit 
• Average change in BCVA from Baseline over the period Week 4 to Week 48 
• Average change in BCVA from Baseline over the period Week 12 to Week 48 
• Number and percentage of subjects with a gain in BCVA of 15/10/5 letters or more from 
Baseline to each postbaseline visit 
Note: Subjects with BCVA value of 84 letters or more at a postbaseline visit will be 
considered as responders for the corresponding endpoint. This is to account for a ceiling 
effect, e.g. for the’ ≥15-letter gain’ endpoint, for those subjects with BCVA values at 
Baseline ≥ 70 letters. 
• Number and percentage of subjects with an absolute BCVA of 73 letters or more at each 
visit 
• Number and percentage of subjects with a loss in BCVA of 15/10/5 letters or more from 
Baseline to each postbaseline visit

• Change in CSFTtot from Baseline to each postbaseline visit 
• Average change in CSFTtot from Baseline over the period Week 36 through Week 48 
• Average change in CSFTtot from Baseline over the period Week 4 to Week 48 
• Change in CSFTns from Baseline to each postbaseline visit 
• Change in area of CNV within the lesion from Baseline to Weeks 12 and 48 from FP/UWF-
C 
• Number and percentage of subjects with presence of subretinal and/or intraretinal fluid 
(central subfield) at each postbaseline visit (and specifically Week 16 and Week 48) 
• Number of visits with simultaneous absence of subretinal and intraretinal fluid (central 
subfield) during Week 36 to Week 48 
• Number and percentage of subjects with presence of subretinal fluid (central subfield) at 
each postbaseline visit 
• Number and percentage of subjects with presence of intraretinal fluid (central subfield) at 
each postbaseline visit 
• Number and percentage of subjects with presence of sub RPE fluid (central subfield) at each 
postbaseline visit

Secondary efficacy endpoints related to efficacy at the end of the matched treatment phase: 
• Change in CSFTtot from Baseline at Week 16 
• Number and percentage of subjects with presence of subretinal and/or intraretinal fluid 
(central subfield) at Week 16 
• Number and percentage of subjects with q8w treatment need identified at Week 16 
2.7.2 
Statistical hypothesis, model, and method of analysis 
No hypothesis will be tested for the secondary efficacy endpoints listed in the above Section 
2.7.1. 
These endpoints will be summarized and presented descriptively, based on the FAS with LOCF 
imputation for missing or censored data if not otherwise specified. Details on data handling 
such as missing values are described in Section 2.7.3. 
Continuous endpoints: 
The continuous secondary endpoints will be analyzed using ANOVA models. The LSM 
estimates for each treatment and for the treatment difference (brolucizumab – aflibercept), 
including 90% CIs will be presented. 
For the ANOVA analysis of BCVA-related endpoints, baseline BCVA category (≤55, ≥56-≤70, 
≥71 letters) and age category (<75, ≥75 years) will be considered as a class variable. For the 
ANOVA analysis of CSFT-related endpoints, baseline CSFT category (<400, ≥400 µm ) will be 
used instead of baseline BCVA as a class variable. For the ANOVA analysis of CSFTns-related 
endpoints, baseline CSFTns category (< overall median value, ≥ overall median value) will be 
used instead of baseline BCVA as a class variable. For the ANOVA analysis of CNV-related 
endpoints, baseline type of CNV (predominantly classic, minimally classic, pure occult) will be 
used instead of baseline BCVA as a class variable. 
The line plot of change from baseline in CNV lesion size, CSFTtot and CSFTns on LSM (±SE) 
by visit will also be provided for each treatment arm. 
Binary endpoints: 
For binary endpoints, frequency tables (count and percentage) will be provided by visit. In 
addition, proportions and treatment differences in proportions along with 90% CIs will be 
presented for each time point using a logistic regression with treatment, the corresponding 
baseline status and age category (<75, ≥75 years) as fixed effects.  Bar chart of the endpoints 
related to fluid will be plotted by visit and treatment arm.  
2.7.3 
Handling of missing values/censoring/discontinuations 
Missing data for all the secondary efficacy endpoints will be imputed using the LOCF method 
unless specified otherwise.  
For the LOCF method, missing data will be imputed by the value of the last available non-
missing post-baseline observation. For subjects with no postbaseline values (scheduled or 
unscheduled), the baseline value will be carried forward, as a conservative approach. For 
subjects who discontinue treatment but continue in the study, data collected after start of 
alternative nAMD treatment in the study eye will be censored for the analysis. Censored data

CRTH258A2307 
 
will be replaced by the last available observation prior to the start of alternative nAMDtreatment. 
Missing baseline values will not be imputed.  
For endpoints related to presence of fluids, if baseline visit is reported as “Cannot Grade” or 
“Not Applicable”, then it will be considered as “Absent”; if postbaseline visit is reported as 
“Cannot Grade” or “Not Applicable”, then it will be considered as missing and LOCF method 
for imputation will be applied.

Safety analyses 
Safety endpoints include: 
• Extent of exposure (see Section 2.4.1) 
• Adverse events 
• Deaths 
• Laboratory evaluations 
• Ophthalmic examinations 
• Presence of fibrosis from color fundus photography / ultra-wide field color fundus 
photography 
• Loss in BCVA 
• Vital signs 
There are no formal safety hypotheses in this study. All safety analyses will be performed using 
the Safety Analysis Set. 
Except for imputation of partial dates for AEs, no imputations will be performed for missing 
values in the safety analyses. 
In all summary tables, unless otherwise specified, data collected after the subject discontinued 
study treatment and started alternative nAMD treatment in the study eye will be censored (data 
on the day the subject started alternative nAMD treatment will be included). 
2.8.1 
Adverse events (AEs) 
A treatment-emergent adverse event (TEAE) is defined as any adverse event that develops after 
initiation of the study treatment or any event already present that worsens following exposure 
to the study treatment. Only TEAE will be presented in the summary tables. 
Adverse events will be coded using the MedDRA dictionary and presented by system organ 
class (SOC) and preferred term (PT). TEAEs will be analyzed based on the number and 
percentage of subjects with at least one AE in the category of interest. 
The number and proportion of subjects with TEAEs will be summarized in the following ways 
by treatment arm:

In all summary tables listed above, unless otherwise specified, data collected after the subject 
discontinued study treatment and started alternative nAMD treatment in the study eye will be 
censored.  
Subject listings of all adverse events will be provided. Deaths and other serious or clinically 
significant non-fatal adverse events will be listed separately. 
The MedDRA version used for reporting the AEs will be described in a footnote. 
2.8.1.1 
Adverse events of special interest / grouping of AEs 
An adverse events of special interest (AESI) is one of scientific and medical interest to the 
sponsor and include the following:  
• Endophthalmitis 
• Intraocular Inflammation 
• Retinal Vascular Occlusion 
  


Novartis 
For business use only 
Page 29 of 45

CRTH258A2307 
 
 
Incidence of adverse events of special interest will be tabulated by treatment arm. AESIs in 
study eye and other safety topics of interest will be identified via the RTH258 electronic case 
retrieval strategy (eCRS). The eCRS that is current at the time of database lock will be used and 
AESIs and other safety topics of interest will be identified where the flag Core safety topic risk 
(SP) = ‘Y’. 
2.8.1.2 
Adverse event reporting for clinical trial safety disclosure  
For the legal requirements of ClinicalTrials.gov, two required tables on TEAEs which are not 
serious adverse events with an incidence greater than X% and on treatment emergent AEs and 
SAEs suspected to be related to study treatment will be provided by SOC and PT on the safety 
analysis set. Ocular TEAEs for study eye and fellow eye will be considered separately. 
If for the same subject, several consecutive AEs (irrespective of study treatment causality, 
seriousness and severity) occurred with the same SOC and PT: 
• a single occurrence will be counted if there is ≤ 1 day gap between the end date of 
the preceding AE and the start date of the consecutive AE 
• more than one occurrence will be counted if there is > 1 day gap between the end 
date of the preceding AE and the start date of the consecutive AE 
For occurrence, the presence of at least one SAE (respectively non-SAE) has to be checked in 
a block e.g. among AEs in a ≤ 1 day gap block, if at least one SAE is occurring, then one 
occurrence is calculated for that SAE. 
The number of deaths resulting from SAEs suspected to be related to study treatment, and SAEs 
irrespective of study treatment relationship will be provided by SOC and PT. 
2.8.2 
Deaths 
A summary of treatment emergent deaths will be presented by primary SOC and PT.  
All deaths recorded in the clinical database will be listed. 
2.8.3 
Laboratory evaluations 
Laboratory data will be presented graphically using boxplots of absolute change from baseline 
values by treatment arm and visit. No summary by visit tables will be provided. 
A summary table with counts and percentage of subjects satisfying the criteria representing 
clinically notable values given in Section 5.3 at any visit will be presented. A listing of subjects 
satisfying at least one criterion in Table 5-1 at any visit will also be presented. 
2.8.4 
Other safety data 
2.8.4.1 
Ophthalmic examinations 
Intraocular pressure (IOP) values summarized and listed in safety analyses refer to assessments 
for study eye.

CRTH258A2307 
 
Descriptive summaries of pre-injection change from baseline in intraocular pressure (IOP) 
values for the study eye will be presented  at each study visit by treatment arm, considering line 
plots of the mean change in IOP values with error bars representing ± SE. The x-axis will be 
study visit and the y-axis will be the change from Baseline value. No summary by visit tables 
will be provided. 
The number and percentage of subjects with pre-injection IOP >30 mmHg at any visit will be 
summarized.  
Post-injection IOP is to be assessed within 60 minutes after injection and if ≥25 mmHg, the 
assessment should be repeated until back to normal. Summary tables with counts and percentage 
of subjects with an IOP increase of ≥10, ≥20 mmHg from pre-injection to post-injection at any 
visit for the study eye will be presented. A listing for subjects with any post-injection IOP 
increase of ≥10 mmHg from pre-injection IOP at any visit for the study eye will be presented. 
A summary table with counts and percentage of subjects with observed pre-injection IOP ≥ 21 
mmHg at 3 consecutive scheduled visits will be presented. A visit with missing pre-injection 
IOP is considered to meet the ≥ 21mmHg criterion if the proceeding and the following visits 
meet the criterion that pre-injection IOP ≥ 21mmHg. For example, if schedule visit X has 
missing pre-injection IOP and pre-injection IOP ≥ 21mmHg is observed for both visit X-1 and 
X+1, the subject is considered to meet the criteria at visit X as well. 
A listing of subjects with any IOP > 30 mmHg will be presented. 
The abnormal findings via slit-lamp and indirect fundus examinations deemed as clinically 
significant by the investigator and reported as AE/SAE will be included in the safety analysis 
on AE/SAE.   
2.8.4.2 
Presence of fibrosis 
A summary table with counts and percentage of subjects with presence of fibrosis (central 
subfield) in study eye from color fundus photography/ ultra-wide field color fundus photograph 
will be presented by visit. Fibrosis data will be presented in a subject listing. 
2.8.4.3 
Loss in BCVA 
The numbers and percentages of subjects with a loss in BCVA ≥15, ≥30 letters (study eye) from 
baseline to the last visit, and maximum loss at any postbaseline visit will be presented.  
2.8.4.4 
Vital signs 
Vital signs include assessment of sitting blood pressure (systolic and diastolic pressure in mm 
Hg) and pulse (beats per minute). 
A summary table with numbers and percentages of subjects satisfying the criteria given in Table 
5-2 of Section 5.3 at any visit will be presented. A listing of subjects satisfying at least one 
criterion in Table 5-2 will also be presented. 
A line plot of mean change from baseline in each vital sign parameter by study visit and 
treatment with error bars representing ±SE will be presented. The x-axis will be study visit and 
the y-axis will be the mean change from baseline value.

Pre-defined imaging parameters in the study eye associated with intraocular inflammation 
and/or retinal vascular occlusion as assessed by the CRC will be listed. 
2.9 
Pharmacokinetic endpoints   
PK parameters of brolucizumab in serum will be assessed in subgroup with  approximately 12 
PK consented subjects in brolucizumab arm. 
A PK profile is considered evaluable if all the following conditions are satisfied: 
• Subject receives the planned first dose of brolucizumab 
• Subject provides at least one primary PK parameter of brolucizumab (e.g. Cmax or AUC) 
Pharmacokinetic parameters including but not limited to those presented in Table 2-5 will be 
determined using Phoenix WinNonlin (Version 8.3 or higher) using non-compartmental 
method(s). Descriptive summary statistics for PK parameters will include n (number), mean 
(arithmetic and geometric), SD, SE (arithmetic and geometric), and CV (arithmetic and 
geometric), median, minimum and maximum. An exception to this is Tmax where median, 
minimum and maximum will be presented. In addition, half-life (T1/2) will be summarized 
using Harmonic mean along with the Jack-Knife estimate for standard deviation. 
For PK consented group in brolucizumab arm, line plots showing the mean serum concentration 
± standard error versus nominal sample collection time will be presented, and the individual 
line plots will also be presented. 
Descriptive statistics will be presented for serum concentration levels for all the subjects with 
PK sample collection at each sampling time. Serum concentration values will also be listed by 
treatment subject and time point. Summary statistics will include n (number of values to be 
reported), arithmetic and geometric mean, median, SD, SE, CV, and geometric SE, geometric 
CV, minimum and maximumSamples collected outside of the protocol defined visit window 
will be excluded from that visit/timepoint for the purpose of presenting descriptive summaries 
by time point.At each time point, one-half the lower limit of quantitation (LLOQ) will be used 
for analysis when a subject has a determined concentration value below the LLOQ. For the 
purpose of calculating descriptive statistics for serum concentrations, post-injection 
concentrations below the LLOQ will be treated as half of LLOQ in summary statistics. If the 
mean was less than the LLOQ, it was reported as being Below the Limit of Quantitation (BLQ) 
within the summary tables.

Anti-drug antibodies (ADA) 
Collection of blood for ADA assessment will be done at screening, Weeks 4, 12, 24, 36, 48 and 
exit/premature discontinuation. Analyses will be performed only in brolucizumab treatment arm. 
ADA status is defined using the following criteria. The pre-dose is referring to screening 
assessment and the post-dose is referring to postbaseline assessment in the following definition: 
• ADA negative: 
- ADA negative at all time points (pre-dose and post-dose) 
- ADA negative at pre-dose and no titer values above 40 at all other time points 
- ADA titer of 40 at pre-dose but negative at all other time points 
• ADA positive without boost: 
- ADA positive at pre-dose, post-dose titer values do not increase from pre-dose by 
more than 3-fold (1 dilution) at any time point 
• Induced: 
- ADA negative at pre-dose, post-dose titer value of 120 or more increase 
• Boosted: 
- ADA positive at pre-dose, post-dose titer values increase from pre-dose by more 
than 3-fold (1 dilution) at any time point 
The number and percentage of subjects according to their integrated ADA status (ADA negative, 
ADA positive without boost, induced, boosted) will be presented. In addition, tabulations will 
be presented for ADA titer pattern.  
The number and percentage of subjects with positive neutralizing antibody (NAb) will be 
summarized by ADA assessment visit for subjects with ADA titer values (ADA positive). 
The line plots showing the BCVA change from baseline up to Week 48 for the study eye by 
ADA status (pre-existing and integrated status up to Week 48) and NAb status (pre-existing and 
integrated status up to Week 48) among all the subjects and the subjects without AESI in study 
eyewill be generated. 
The summary tables of the incidence of AESIs in study eye by ADA status (pre-existing, pre-
existing nAb, integrated ADA and integrated nAb status up to Week 48) will be presented. 
Subject listings of all ADA titer values and NAb status will be presented for all subjects in the 
brolucizumab arm. Samples collected at unscheduled visits will not be part of the analysis. 
Systemic exposure of brolucizumab will be measured concomitantly with ADA levels for 
interpretation purposes.   
2.11 
Patient-reported outcomes 
The Visual Function Questionnaires (VFQ-25) will be scored (total and subscale scores) at 
Baseline, Week 24 and EOS visits. Absolute scores and the absolute changes from baseline 
will be calculated and summarized descriptively using the FAS. PRO data at EOS which is 
different from Week 48 will be excluded. 
Further details on the scoring algorithm and analysis are provided below.

Each subscale score has a range of 0 to 100 inclusive and will be calculated from the re-scaled 
raw data as described in Table 2-6. A missing response will not be re-scaled (except for the 
response to question 15c, see below, which will be re-set to 0 if the response to question 15b is 
1).

Descriptive summary statistics for change from baseline to post baseline VFQ assessments will 
be presented using the FAS for the composite and subscale scores. Mean changes from baseline 
to each post baseline VFQ assessments visits will be compared between the brolucizumab arm 
and the aflibercept arm. Appropriate statistical methods (e.g. ANCOVA model with treatment 
as a fixed effect factor and corresponding baseline value of the endpoint in the model) will be 
used for treatment group comparison. Additionally, descriptive statistics will also be presented 
for the general health score.   
The VFQ-25 composite score and subscale scores will not be listed.

Sample size calculation 
A sample size of 175 subjects per treatment arm is sufficient to demonstrate noninferiority 
(margin = 4 letters) of brolucizumab 6 mg versus aflibercept 2 mg with respect to the BCVA 
change from Baseline to Week 48 at a one-sided alpha level of 0.05 with a power of 
approximately 80% assuming equal efficacy and a common standard deviation of 15 letters. A 
power of at least 80% can be expected for the first key secondary endpoint assuming that 
averaging BCVA change from Baseline over the 4 time points will not lead to an increase in 
the standard deviation. To account for a drop-out rate of 10%, a total of 195 subjects will be 
randomized per treatment arm.

Before imputing AE start date, find the AE start reference date. 
1. If the (imputed) AE end date is complete and the (imputed) AE end date < treatment start 
date then AE start reference date = min (informed consent date, earliest visit date). 
2. Else AE start reference date = treatment start date. 
Impute AE start date - 
1. If the AE start date year value is missing, the date uncertainty is too high to impute a rational 
date. Therefore, if the AE year value is missing, the imputed AE start date is set to NULL. 
2. If the AE start date year value is less than the treatment start date year value, the AE started 
before treatment. Therefore: 
a. If AE month is missing, the imputed AE start date is set to the mid-year point 
(01JulYYYY). 
b. Else if AE month is not missing, the imputed AE start date is set to the mid-month point 
(15MONYYYY). 
3. If the AE start date year value is greater than the treatment start date year value, the AE 
started after treatment. Therefore: 
a. If the AE month is missing, the imputed AE start date is set to the year start point 
(01JanYYYY). 
b. Else if the AE month is not missing, the imputed AE start date is set to the later of (month 
start point (01MONYYYY), AE start reference date + 1 day). 
4. If the AE start date year value is equal to the treatment start date year value: 
a. And the AE month is missing the imputed AE start date is set to the AE reference start 
date + 1 day. 
b. Else if the AE month is less than the treatment start month, the imputed AE start date is 
set to the mid-month point (15MONYYYY).

c. Else if the AE month is equal to the treatment start date month or greater than the 
treatment start date month, the imputed AE start date is set to the later of (month start point 
(01MONYYYY), AE start reference date + 1 day). 
If complete (imputed) AE end date is available and the imputed AE start date is greater than the 
(imputed) AE end date, then imputed AE start date should be set to the (imputed) AE end date. 
5.1.2.2 
AE end date imputation 
1. If the AE end date month is missing, the imputed end date should be set to the earliest of 
the (31DECYYYY, date of death). 
2. If the AE end date day is missing, the imputed end date should be set to the earliest of the 
(last day of the month, date of death). 
3. If AE year is missing or AE is ongoing, the end date will not be imputed. 
4. If the imputed AE end date is less than the existing AE start date then use AE start date as 
AE end date.

Concomitant medication/procedure date imputation 
5.1.3.1 
Concomitant medication/procedure start date imputation 
In order to classify a medication/procedure as prior and prior/concomitant, it may be necessary 
to impute the start date. 
Completely missing start dates will be set to one day prior to treatment start date. As a 
conservative approach, such treatments will be classified as prior and concomitant (and 
summarized for each output). 
Concomitant treatments with partial start dates will have the date or dates imputed.

2. If the CM/PR start date year value is less than the treatment start date year value, the CM/PR 
started before treatment. Therefore: 
a. If the CM/PR month is missing, the imputed CM/PR start date is set to the mid-year point 
(01JulYYYY). 
b. Else if the CM/PR month is not missing, the imputed CM/PR start date is set to the mid-
month point (15MONYYYY). 
3. If the CM/PR start date year value is greater than the treatment start date year value, the 
CM/PR started after treatment. Therefore: 
a. If the CM/PR month is missing, the imputed CM/PR start date is set to the year start 
point (01JanYYYY). 
b. Else if the CM/PR month is not missing, the imputed CM/PR start date is set to the month 
start point (01MONYYYY). 
4. If the CM/PR start date year value is equal to the treatment start date year value: 
a. And the CM/PR month is missing or the CM/PR month is equal to the treatment start 
date month, then the imputed CM/PR start date is set to one day prior to treatment start 
date. 
b. Else if the CM/PR month is less than the treatment start date month, the imputed CM/PR 
start date is set to the mid-month point (15MONYYYY). 
c. Else if the CM/PR month is greater than the treatment start date month, the imputed 
CM/PR start date is set to the month start point (01MONYYYY). 
If complete (imputed) CM/PR end date is available and the imputed CM/PR start date is greater 
than the (imputed) CM/PR end date, then imputed CM/PR start date should be set to the 
(imputed) CM/PR end date. 
5.1.3.2 
Concomitant medication/procedure end date imputation 
1. If the CM/PR end date year value is missing, the date uncertainty is too high to impute a 
rational date. Therefore, if the CM/PR end year value is missing or ongoing, the imputed 
CM/PR end date is set to NULL. 
2. Else, if the CM/PR end date month is missing, the imputed end date should be set to the 
earliest of the (treatment end date, 31DECYYYY, date of death). 
3. If the CM/PR end date day is missing, the imputed end date should be set to the earliest of 
the (treatment end date, last day of the month, date of death). 
4. If the imputed CM/PR end date is less than the existing CM/PR start date, use the CM/PR 
start date as the imputed CM/PR end date. 
5.1.4 
Medical history date of diagnosis imputation 
Completely missing dates and partially missing end dates will not be imputed. Partial dates of 
diagnosis will be compared to the treatment start date. 
1. If DIAG year < treatment start date year  
a. and DIAG month is missing, the imputed DIAG date is set to the mid-year point 
(01JULYYYY)

2. If DIAG year = treatment start date year 
a. and (DIAG month is missing OR DIAG month is equal to treatment start month), 
the imputed DIAG date is set to one day before treatment start date 
b. else if DIAG month < treatment start month, the imputed DIAG date is set to the

AEs coding/grading 
AEs are coded using the MedDRA terminology.  
AEs severity is assessed by investigators according to the following:  
• mild: usually transient in nature and generally not interfering with normal activities 
• moderate: sufficiently discomforting to interfere with normal activities 
• severe: prevents normal activities

Statistical models 
5.4.1 
Primary and first key secondary analysis 
The primary endpoint (change from baseline in BCVA at Week 48) and first key secondary 
endpoint (average change from baseline in BCVA over the period Week 36 through Week 48) 
will be analyzed using ANOVA models. 
 
Analysis of Variance (ANOVA) 
The following ANOVA model will be used for the primary and first key secondary efficacy 
endpoints: 
<change from Baseline in BCVA at Week 48> <average change from Baseline in BCVA 
from Week 36 to Week 48> = intercept + treatment + Baseline BCVA category + age 
category + error. 
For the above analysis, the data structure is one record per subject.  
The SAS Proc MIXED will be used to perform the ANOVA analyses. 
 
Mixed Model Repeated Measures (MMRM) 
The following MMRM model will be used for the supportive analysis of the primary and first 
key secondary efficacy variables: 
<change from Baseline in BCVA> = intercept + treatment + Baseline BCVA category 
+ age category + visit + treatment*visit + error. 
 
The SAS Proc MIXED will be used to perform the MMRM analyses. 
Note: For the above MMRM analysis, the data structure is one record per subject per scheduled 
visit. The data will include all subjects and have records for all scheduled visits, regardless of 
whether the assessment was missed or not at a given visit. Missing values will NOT be imputed 
using LOCF. Instead, the value will be passed to the model as missing. 
5.4.2 
Other secondary efficacy analysis 
5.4.2.1 
ANCOVA model for continuous variables 
The continuous efficacy variable (such as VQF-25 score change from baseline) will be analyzed 
using an ANCOVA model adjusted for treatment, age category, and the corresponding baseline 
VFQ-25 score. 
The SAS Proc MIXED will be used to perform the ANCOVA analyses.

CRTH258A2307 
 
5.4.2.2 
Logistic regression for proportion variables 
The binary efficacy variables will be analyzed using the logistic regression model adjusted for 
treatment, age category, corresponding baseline variables, and other covariates if necessary.  
The SAS Proc LOGISTIC will be used.  
Note: 
• For the above analyses, the data structure is one record per subject and visit. The least 
square mean estimates obtained from the above model are for the log-odds ratios. 
• The estimated difference in proportions and the corresponding 90% confidence intervals 
will be obtained by applying the bootstrap method. The pseudo SAS code to derive the 
treatment difference and 90% CI from the least square mean output of the fitted model 
will be provided in the programming specification document. 
5.4.2.3 
KM estimate for time to event variables 
Within the brolucizumab treatment arm, the proportion of subjects maintained at q12w up to 
Week 48 will be estimated from Kaplan Meier time-to-event analyses for the event ‘first q8w-
need’ applying event allocations (in case of lack of efficacy and/or lack of safety) and censoring 
as described in Section 2.6.2 and Section 2.6.3.  
A corresponding 90% CI will be derived from the LOGLOG transformation, using SAS Proc 
Lifetest, with CONFTYPE = LOGLOG.

Table 5-4 lists the non-protocol deviations (analysis restrictions) that may lead to exclusion 
from per-protocol analysis. Analysis restrictions (ARs) address limitations in the evaluability 
which result from missing or confounded data with underlying background not qualifying as a 
PD (e.g. early study terminations, early treatment discontinuations, missing DAA or BCVA 
assessments). 
Rules of determination of ARs by programming will be specified in the Programming Data 
Specifications (PDS) documentation.

Subject evaluability is based on two components: 
• Exclusion from an analysis set  
• Censoring of specific data points from an analysis (see Section 5.6). 
The consequence of an AR on the evaluability depends on the underlying reason, while three 
different categories of reason are considered: 
• Lack of efficacy of the study treatment (=1) 
• Lack of safety / tolerability of the study treatment (=2) 
• Other (=0) 
Remark: Based on the concept of PD’s, their underlying reason will always be ‘0’. 
As a general rule, ARs with a reason of 1 or 2 do not lead to an exclusion from any analysis set, 
as a potential link between exclusion reason and treatment would constitute a source for 
systematic bias. 
Table 5-5 describes subject classification with regards to analysis sets:

Censoring rules for analysis 
PDs and ARs that are considered to be critical for the subject evaluability regarding the primary 
and key secondary endpoints are described in Section 5.5. 
The focus of the ARs is the identification of censoring related to the analysis of BCVA and 
q12w proportion as derived from DAA and described in Section 2.6.3. Censoring is only applied 
in case the underlying reason for a confounded DAA is assessed as ‘0’. Censoring of BCVA 
and DAA applies both to FAS and PPS. 
Table 5-6 summarizes the concepts of censoring for the key parameters BCVA and q12w-status/ 
DAA applied to the two efficacy analysis sets, FAS and PPS, as well as the details for the timing 
of censoring for BCVA and DAA. 
In case a subject has multiple PDs/ARs with impact on subject’s evaluability the following rules 
are applied: 
• A subject is excluded from an analysis set if at least one PD or AR with this consequence 
was identified (see Table 5-5). This rule is built on the concept of the medical assessment 
of the ‘reason’ which considers the reason of an earlier event to potentially also be the 
reason for following PDs or ARs. 
• In case of multiple censoring time points censoring will be performed at the earliest.

considered to be confounded by reasons other than 
lack of efficacy and/or safety. 
 
 
 
 
Censoring: subjects are considered no longer to be 
under risk for a q8w-need identification at later visits. 
Censoring at baseline if above PD/AR occurred prior to

48 without above PD/AR.
