2/Protocol GX28228, Version 8 
PROTOCOL AMENDMENT, VERSION 8: 
RATIONALE 
Protocol GX28228, Version 8 has been amended primarily to reflect the extension of 
study duration for patients in the intravitreal ranibizumab control arm.  Changes to the 
protocol, along with a rationale for each change, are summarized below. 
• 
Study duration for patients in the intravitreal ranibizumab control arm has been 
extended by approximately 4 months to align with the other treatment arms and to 
allow for continued monthly evaluation and study treatment until the Sponsor 
decides, based on the primary analysis results, to either terminate the study and 
discontinue study treatment, or offer patients entry into the Ranibizumab Port 
Delivery System (RPDS) Extension Study.  Primary analysis data is expected to be 
available approximately 4 months after the Month 9 visit of the last patient randomly 
assigned in the study.  The study duration extension for this control arm aligns the 
duration of patient participation for all study treatment arms at approximately 
13−38 months ,dependent on the date of the patient's randomization to the study 
(Sections 3.1 and 4.6.10.5, Figure 2, and Table 3). 
• 
"RPDS Extended Use Life Study" has been replaced with "RPDS Extension Study" 
(Sections 3.1, 3.2, 4.4.2, and 4.6.10.5, and Appendix 1). 
• 
The Secondary Medical Monitor information has been updated (Section 5.4.1). 
 
Additional minor changes have been made to improve clarity and consistency.  
Substantive new information appears in italics.  This amendment represents cumulative 
changes to the original protocol.

Objectives
Efficacy Objectives
The primary efficacy objective for this study is as follows:

To evaluate the relative efficacy of 10-mg/mL, 40-mg/mL, and 100-mg/mL formulations of 
ranibizumab, delivered via the Implant, as measured by the time a patient first requires
Implant refill according to protocol-defined refill criteria
The secondary efficacy objectives for this study are as follows:

To evaluate and compare the relative efficacy of 10-mg/mL, 40-mg/mL, and 100-mg/mL 
formulations of ranibizumab, delivered via the Implant, to that of 10-mg/mL (0.5-mg dose) 
monthly ITV ranibizumab injections, as measured by the change in BCVA from baseline at 
Month 9

To evaluate the efficacy of 10-mg/mL, 40-mg/mL, and 100-mg/mL formulations of 
ranibizumab, delivered via the Implant, with that of 10-mg/mL (0.5-mg dose) monthly ITV 
ranibizumab injections over time, as measured by the change in BCVA from baseline over 
time

To evaluate the efficacy of 10-mg/mL, 40-mg/mL, and 100-mg/mL formulations of 
ranibizumab, delivered via the Implant, with that of 10-mg/mL (0.5-mg dose) monthly ITV 
ranibizumab injections over time, as measured by the change in central foveal thickness 
(CFT, defined as the retinal thickness in the center of the fovea) from baseline over time

To evaluate the functionality of the Implant by assessing that there is no evidence of 
Implant clogging in more than 10% of patients in the Implant arms at Month 9

Ranibizumab Port Delivery System—Genentech, Inc.

Study Design
Description of Study
Study GX28228 is a Phase II, multicenter, dose-ranging, randomized, active treatment (monthly 
ITV injection)-controlled study to evaluate the efficacy, safety, and pharmacokinetics of 
ranibizumab delivered through the Implant using three ranibizumab formulation arms (10 mg/mL, 
40 mg/mL, and 100 mg/mL) compared with the control arm (0.5-mg monthly ITV injections of 
10-mg/mL formulation) in patients with subfoveal neovascular age-related macular degeneration

Comparator
Ranibizumab 0.5-mg monthly intravitreal (ITV) injections of 10-mg/mL formulation
Statistical Methods
Detailed specifications of the statistical methods will be described in the statistical analysis plan 
(SAP).
Primary Analysis
The primary endpoint for this analysis will be time to first meeting refill criteria.  The primary 
analyses will be based on data as of 9 months after last patient’s entry into the study.  For 
patients without any refills prior to or on the cut-off date of 9 months after LPI, the time of refill 
will be censored. The censoring date will be defined as the date of a patient’s last visit before 
the cut-off date of 9 months after LPI, or the date when the patient discontinues from the study, 
whichever occurs first.
The primary analysis population for efficacy is the modified intent-to-treat population defined as 
all randomized patients who were randomly assigned to study treatment receive study 
treatment.  Patients will be summarized by treatment arm and analyzed according to the 
treatment actually received and not according to the treatment they were randomized to receive, 
in the event of a discrepancy.  
To support the dose level selection among the Implant groups, the primary analysis for TTFR 
will include the following pair-wise group comparisons, each with a stratified log-rank test at a 
one-sided significance level of 15%.  The stratification factors to be included are baseline BCVA 
score (65 letters vs. 66 letters) and number of anti-VEGF ITV injections (3 vs. 4).

Implant with 100 mg/mL versus Implant with 10 mg/mL

Implant with 100 mg/mL versus Implant with 40 mg/mL

Implant with 40 mg/mL versus Implant with 10 mg/mL
In addition, the HR for each pair-wise comparison of the treatment arms will be estimated using 
a Cox proportional hazards regression model stratified by baseline BCVA score (65 letters vs.
66 letters) and number of prior anti-VEGF ITV injections (3 vs. 4) with main effects for 
treatment.  Estimated HRs for each pair-wise comparison will be presented with the 
corresponding 80% CIs.  

Ranibizumab Port Delivery System—Genentech, Inc.
20/Protocol GX28228, Version 8
KaplanMeier plots will be provided showing TTFR by implant group.  Median time to first 
meeting refill criteria will be calculated for each treatment arm with the Kaplan Meier method, 
and the corresponding 80% confidence intervals will also be reported.

Moreover, for each treatment group, percentage of patients not meeting the protocol-
defined first refill criteria by Months 4, 5, 6, 7, 8, and 9, derived from Kaplan-Meier 
estimates will be provided.
Determination of Sample Size
This study is exploratory in nature and designed to estimate the time to first refill (TTFR) for 
each of the RPDS treatment arms (10 mg/mL, 40 mg/mL, and 100 mg/mL) enrolling 60 patients 
in each of the RPDS treatment arms.  The sample size of approximately 220 randomized 
patients will be adequate to evaluate the primary objective of the study.  PK/PD modeling and 
simulation was performed to inform key assumptions used in sample size calculation.  Given the 
simulation results, the HR for comparing the 100-mg/mL arm with the 10-mg/mL arm was 
estimated to be 0.66 for TTFR.  Assuming this HR, a total of at least 125 events from all three 
Implant groups is expected at the primary analysis time (approximately 85 events in the 
10-mg/mL group and a higher dose group).  With 85 events, this study will have approximately 
80% power to detect an HR0.66 between the two Implant arms using a log-rank test at a 
one-sided significance level of 15%.  No multiplicity adjustment is planned for this Phase II 
study.
Forty patients in the ITV arm are considered sufficient to compare each device arm versus the 
ITV arm in change in BCVA from baseline through Month 9 (assuming an estimated 
SD 10 letters, a two-sided 80% CI will extend approximately 2.62 letters from the observed 
mean).

BACKGROUND
1.1
BACKGROUND ON AGE-RELATED MACULAR DEGENERATION
Age-related macular degeneration (AMD) is one of the major causes of legal blindness 
in elderly persons in the developed world (Bressler et al. 2011).  Late stage AMD 
includes two morphological subtypes: neovascular AMD and geographic atrophy.  The 
prevalence of neovascular AMD increases exponentially with age, with prevalence 
estimates in the United States in 2011 ranging from 0.5% among those 65 to 69 years of 
age to 14.6% among those 90 years of age or greater (Rudnicka et al. 2012). In the 
next 40 years, the global population aged 60 years and older is projected to increase 
dramatically translating into an increase in the prevalence of neovascular AMD from
23 million in 2010 to 80 million by 2050 (Smith 2010).  The precise causes of AMD 
remain unknown, although numerous risk factors have been identified, including genetic 
(e.g., complement factor H polymorphisms), demographic (e.g., ethnicity), nutritional 
(e.g., lack of antioxidant vitamins, dietary fats, or fish), lifestyle (e.g., smoking), medical 
(e.g., cardiovascular risk factors), environmental (e.g., sun exposure), and ocular factors 
(Chakravarthy et al. 2010).
1.1.1
Pathophysiology of Age-Related Macular Degeneration
AMD is categorized into two subtypes, dry and neovascular, based on clinical 
examination, ocular imaging, and pathologic findings.  In dry AMD, which represents 
approximately 80%90% of AMD cases, damage occurs at the level of the retinal 
pigment epithelium (RPE) and Bruch’s membrane, the basement membrane between 
the RPE and the underlying choriocapillaris.  The most notable early change in dry AMD 
is the accumulation of drusen within the macula and posterior pole of the retina.  Drusen 
are focal deposits of extracellular debris located between the basal lamina of the RPE 
and the inner collagenous layer of Bruch’s membrane. Drusen compositional studies 
have revealed carbohydrates, zinc, nearly 150 proteins, and numerous components of 
the complement system. The largest single component of drusen is lipid, thought to be 
derived from a large lipoprotein of intra-ocular origin (Spaide and Curcio 2010). Early 
dry AMD may not produce symptoms for many years.  However, as drusen continue to 
accumulate, the patient’s central vision can become impaired, sometimes significantly.  
At its most extreme, dry AMD results in widespread loss of the RPE, a condition called 
geographic atrophy that can cause severe central vision loss and legal blindness.
In approximately 10% of dry AMD cases, a conversion to neovascular AMD (nAMD)
occurs over time.  Although nAMD is comparatively rare, prior to the development of 
anti-VEGF therapy, it accounted for the majority of severe vision loss from AMD.  nAMD
is typically characterized by the development of choroidal neovascularization (CNV) 
beneath the macula.  Abnormal capillary vessels and fibrovascular membranes 
proliferate in regions of Bruch’s membrane damage.  The new vessels are abnormally 
permeable, and result in accumulation of exudative fluid and hemorrhage beneath the 
RPE and/or neurosensory retina.  This fluid and hemorrhage can cause acute and, 

Ranibizumab Port Delivery System—Genentech, Inc.
24/Protocol GX28228, Version 8
historically, permanent loss of central vision.  At the end stage, fibrous metaplasia can 
occur, resulting in a chronic subretinal scar (disciform scar; Jager et al. 2008).
The stimuli that result in the development of CNV remain unclear.  However, there is 
significant experimental and clinical evidence implicating vascular endothelial growth 
factor (VEGF)-A in the pathogenesis of nAMD, as discussed in the Ranibizumab Port 
Delivery System (RPDS) Investigator’s Brochure (IB).
1.1.2
Treatment for Age-Related Macular Degeneration
No specific treatment yet exists for dry macular degeneration, although numerous 
therapies have and are being investigated.  The Age-Related Eye Disease Study 
(AREDS), conducted by the National Eye Institute, demonstrated that the rate of 
progression of dry AMD could be decreased by a specific vitamin and mineral 
supplement (AREDS Research Group 2001). 
The treatment of nAMD was significantly impacted by the introduction of anti-VEGF 
therapy. Prior to the availability of anti-VEGF therapy, vision loss could be slowed but 
not reversed. Ranibizumab, a recombinant, humanized monoclonal antibody fragment 
(Fab), which binds to all known isoforms of VEGF-A, was approved by the U.S. Food
and Drug Administration (FDA) for use in neovascular AMD, in June 2006. In November 
2011, a second anti-VEGF therapy, aflibercept, was approved for nAMD in the United 
States, with a similar safety and efficacy profile to ranibizumab.  Both ranibizumab and 
aflibercept therapies require frequent intravitreal (ITV) injections and physician 
monitoring.

BACKGROUND ON RANIBIZUMAB
Ranibizumab is a recombinant humanized immunoglobulin (Ig) G1 kappa isotype 
monoclonal Fab developed by Genentech, Inc. as a therapeutic agent for treating ocular 
vascular diseases by ITV injection.  It binds to and inhibits the biologic activity of human 
VEGF-A.  Ranibizumab is produced by standard recombinant technology methods in an
Escherichia coli expression vector and bacterial fermentation.  Ranibizumab is not 
glycosylated and has a molecular mass of approximately 48,000 Daltons.
Monthly ITV injection of 0.5 mg of ranibizumab was approved for treatment of nAMD by 
the FDA on 30 June 2006. Current U.S. prescribing information also provides 
information on results that may be expected following less frequent than monthly dosing 
(after 3 to 4 monthly injections).  
See the RPDS Investigator Brochure (IB) for details on relevant nonclinical and clinical
ranibizumab information.

1.3
BACKGROUND ON THE RANIBIZUMAB PORT 
DELIVERY SYSTEM
The RPDS is a drug delivery technology that allows physicians to use ranibizumab with 
a sustained drug delivery profile without altering its chemistry and consists of the port 
delivery implant (referred to as the Implant), ancillary devices (Insertion Tool, Initial Fill 
Needle, Refill Needle, and Explant Tool), and ranibizumab (see Figure 1).
The Implant is an intra-ocular refillable device that is surgically placed through the pars 
plana (similar to other surgically implanted ophthalmic devices such as Retisert [Bausch 
and Lomb, FDA approved in 2005]) to allow for a sustained delivery of ranibizumab into 
the vitreous. After insertion of the Implant, the proximal end of the Implant is
subconjunctival but external to the sclera, with the body of the Implant extending into the
vitreous.  The Implant is designed to be used in conjunction with ranibizumab to 
precisely control the rate and duration of drug delivery and is refillable through the 
Implant septum in situ.  
The following are the intended uses of the RPDS components:

Implant: The Implant is intended to be inserted through the pars plana of the eye to 
deliver ranibizumab in a controlled manner into the vitreous humor. The physician 
will initially fill the reservoir with the drug and will refill it in accordance with the 
instructions for use.  Contraindication:  the RPDS is contraindicated for use with 
medications other than ranibizumab.

Insertion Tool:  The Insertion Tool is a component designed to a) hold the Implant 
during sterilization and insertion, b) assist with filling of the Implant before insertion, 
and c) enable insertion of the Implant through a pars plana sclerotomy.

Initial Fill Needle: The Initial Fill Needle is a custom 33G Luer-Lock needle 
designed to perform the initial fill of the Implant while the Implant is held in the 
Insertion Tool.

Refill needles: The Refill Needle is a custom Luer-Lock needle designed to 
simultaneously exchange (in situ) any remaining old drug product in the Implant
reservoir with new drug product.

Explant Tool: The Explant Tool is a component designed to enable the removal of 
the Implant from the posterior segment of the eye after resection of the conjunctiva 
and removal of any scar tissue.
For additional RPDS details (e.g., fill, insertion, refill, and explantation of the Implant), 
consult the RPDS instructions for use (IFU) document and the RPDS IB.

The Implant has been investigated in a prospective, Phase I, open-label study in patients 
with nAMD, conducted by the device developer, ForSight VISION 4, Inc. (FSV4), at a 
single site in Latvia.  The study investigated the safety, tolerability, and duration of 
ranibizumab exposure delivered with the Implant.  This Phase I Implant was composed 
of biocompatible materials (polymethyl methacrylate, silicone, 316L stainless steel, 
see Table 1).  For further Phase I study details, see Section 1.4 and the RPDS IB.

While the size and shape of the Implant is unchanged between the Phase I and II 
studies, material changes were made to improve functionality and reliability of the 
Phase II Implant.  These changes include the use of polysulfone for the Implant body 
and encapsulation of the subconjunctival Implant retention features with silicone.  
Changes to the release control element (RCE) porosity and tortuosity were made 
between the Phase I and Phase II Implant designs to enable the use of higher 
concentrations of ranibizumab during Phase II.  A change in material of the RCE from 
stainless steel to titanium was also implemented to take advantage of the superior 
physical and chemical properties of titanium.
Phase I RPDS Study
The safety, tolerability, and duration of ranibizumab exposure delivered through the 
Implant were investigated in a Phase I prospective, open-label study in a nAMD patient 
population by FSV4 at a single site in Latvia.  Patient enrollment was initiated in 
August 2010, and the study assessed the safety of the RPDS in 20 eyes through the 
collection and analysis of adverse events and complications, including procedure-related 

Ranibizumab Port Delivery System—Genentech, Inc.
28/Protocol GX28228, Version 8
adverse events, device-related adverse events, ranibizumab-related adverse events, 
and all general health and patient-reported adverse events. 
All 20 patients completed the planned 12-month treatment phase of the Phase I study. 
At Month 12, 6 patients underwent per-protocol planned Implant removal and exited the 
study after completion of the 13-month visit.  The 14 remaining patients were eligible for 
an additional safety-monitoring phase of the protocol.  One patient was lost to follow-up 
after 12 months.  The remaining 13 patients continued in the safety-monitoring phase; 
one patient was subsequently lost to follow up after 21 months.  Follow up data up to 
36 months is available for the remaining 12 patients.
No patients were treated via the Implant after the first 12 months of the study, with the 
remaining 14 implanted patients returning for quarterly safety visits.
A total of 95 adverse events have been reported in this study as of 26 February 2015:  
87 during the 12-month treatment phase and 8 during the additional 2-year safety 
monitoring phase.  Of the 87 adverse events during the 12-month treatment phase, 
76 were considered related (possibly, probably, or definitely) to the Implant insertion
procedure, the refill procedure, the Implant removal procedure, or drug treatment.  
These 87 reported adverse events occurred in 20 out of 20 (100%) enrolled patients.
Among the 76 study related adverse events, the most frequent adverse events were 
conjunctival hyperemia (59%), vitreous hemorrhage (7%), hyphema (7%), VA decrease 
(5%), eye dryness (4%), and conjunctival edema (3%).  Conjunctival hyperemia 
occurred in 19 of 20 patients (95%), for a total of 45 events. The majority of these events 
(44/45, 98%) were considered mild and one was considered moderate. The average 
duration of these events was 8 days, with all resolving over a range of 3 to 48 days from 
onset.  This adverse event was observed typically following Implant insertion and 
Implant refill procedures.
Of the 76 study-related adverse events, 30 were considered by the Investigator to be 
possibly or definitely related to the Implant insertion procedure.  These adverse events 
occurred in 15 patients.  The most frequent adverse events related to the Implant 
insertion procedure were conjunctival hyperemia (55% of the patients), vitreous 
hemorrhage (25%), hyphema (15%), and VA decrease (15%).  Single adverse events 
were reported as related to the Implant insertion procedure:  endophthalmitis (5% of the 
patients) and traumatic cataract (5%). A single adverse event of retinal pigment epithelial 
tear (5%) was reported as possibly related to the Implant placement. The number of 
adverse events related to the Implant insertion procedure in the first 10 patients (Patient 
Group 1) was greater (63% versus 19%) than that observed in the second 10 patients 
(Patient Group 2), suggesting that refinements in surgical instrumentation, training, and
surgical experience that occurred during the trial may have in part mitigated the risk of 
the device placement procedure in Patient Group 2.

Ranibizumab Port Delivery System—Genentech, Inc.
29/Protocol GX28228, Version 8
A total of 96 Implant refill procedures were performed in the study. The most frequently 
reported adverse events considered to be related to Implant refill on a per-procedure 
basis by the investigator were conjunctival hyperemia (33%), eye dryness (2%), vitreous 
haze (2%), increased lacrimation (1%), and ocular discomfort (1%).The adverse event 
rate per Implant refill procedure was 38%.  These adverse events were mild in severity 
and the average duration to resolution was seven days.
Six patients underwent planned removal of the Implant at the 12-month visit as 
scheduled in the protocol.  All of these patients were in Group 1. Of these 6 patients, 
4 patients experienced 5 adverse events related to the Implant removal procedure:  two
incidents of conjunctival hyperemia (33%) and single incidences of hyphema (17%), VA 
decrease (17%), and conjunctival hemorrhage (17%).  All adverse events related to the 
implant removal procedure resolved within 7 days.
There were six reported serious adverse events during the treatment phase of the study.  
Four study-related serious adverse events were reported: two incidents of decreased 
VA consequent to adverse events of vitreous hemorrhage, one incident of 
endophthalmitis, and one incident of decreased VA consequent to the incident of 
endophthalmitis.  Two non-study-related serious adverse events were reported: gastric 
adenocarcinoma and rotavirus infection.  The two incidents of vitreous hemorrhage were 
likely caused by post-operative bleeding and were determined to be related to the 
Implant insertion procedure.  The single incident of endophthalmitis was observed at the 
2-week post-Implant insertion visit and was considered possibly related to the Implant 
insertion procedure.  The duration of this event was 14 days.
Of the 76 study-related adverse events, 7 were ongoing at the time of study exit.  These 
ongoing events were vitreous haze (3), and single incidents of vitreous hemorrhage, VA 
decrease, foreign body sensation in the eye, and retinal pigment epithelium tear.  
Thirteen patients entered the 24-month safety-monitoring phase (one patient was lost to 
follow-up after the 12-month follow-up); out of 13 patients, 12 completed the 
safety-monitoring phase and 1 was lost to follow-up after 21 months.  There were a total 
of eight reported adverse events during the safety-monitoring phase of the study.  Four 
adverse events were considered related (possibly, probably, or definitely) to the Implant 
insertion procedure, the refill procedure, or drug treatment.  These related adverse 
events were cataract progression (3) and a single incident of mild ocular discomfort.  
Two additional incidents of cataract progression, one incident of blurred vision, and one 
incident of leg edema were not considered study-related by the investigator.  No serious 
adverse events were reported during the safety-monitoring phase.

30/Protocol GX28228, Version 8
There were no patient deaths during the 12-month treatment phase (the status of the 
2 patients lost to follow-up during the 24-month extended follow-up phase was not able 
to be confirmed), no adverse events led to patient withdrawal or dose reduction, and no 
adverse events represented a previously unsuspected important adverse effect of the 
device (implantation procedure or Implant).

1.4
STUDY RATIONALE AND BENEFIT-RISK ASSESSMENT
As a result of the chronic, progressive nature of nAMD, frequent ranibizumab ITV 
injections continue for extended periods for many patients.  Pivotal studies of 
ranibizumab in nAMD (Studies FVF2598g and FVF2587g) demonstrated significant and 
well-maintained visual acuity (VA) outcomes with monthly 0.5 mg ITV injections for 
2 years.  Trials that investigated less frequent than monthly dosing (Study FVF3192g 
and Lalwani et al. 2009) showed that visual outcomes were not as well maintained with 
more intermittent dosing schedules.  A recent trial that compared monthly to PRN 
ranibizumab ITV administration (Study FVF4579g) showed comparable efficacy and 
maintenance of visual and anatomic improvements for 2 years between the two 
regimens.  However, all patients were evaluated monthly to determine the need for 
re-treatment and still required frequent ITV injections.  The mean number of ranibizumab 
ITV injections through month 24, with the 0.5-mg dose, was 21.4 for the monthly
treatment arm and 13.3 for the PRN treatment arm. In clinical practice, frequent office 
monitoring visits are required and regular injections are necessary to maintain optimal
vision gains.  Frequent office visits place a significant burden on patients and their 
caregivers, as well as treating physicians and the healthcare system. Sustained release 
of ranibizumab from the Implant is an alternate dosing method that may result in less 
frequent need of re-treatment than monthly dosing with ITV injections.  This decrease in 
treatment burden could possibly reduce the risk of ITV injectionrelated adverse events, 
increase compliance, and reduce the burden to patients, their caregivers, and the 
healthcare system, while maintaining optimum visual outcomes.
The safety, tolerability, and duration of ranibizumab exposure delivered through the 
Implant were investigated in a Phase I prospective, open-label study in a nAMD patient 
population by FSV4 at a single site in Latvia.  Patient enrollment was initiated in August 
2010 and the study was completed in July 2013. The study assessed the safety of the 
RPDS in 20 eyes through the collection and analysis of adverse events and 
complications, including procedure-related adverse events, device-related adverse 
events, ranibizumab-related adverse events and all general health and patient-reported 
adverse events. Secondary endpoints of VA and optical coherence tomography (OCT)
change were also collected.
All 20 patients completed the 12-month treatment phase of the Phase I study. At 
month 12, 6 patients underwent per-protocol planned Implant removal and exited the 
study after completion of the 13-month visit.  Complete 13-month data are available for 

Ranibizumab Port Delivery System—Genentech, Inc.
31/Protocol GX28228, Version 8
these 6 explanted patients.  The 14 remaining patients completed an additional 2-year 
safety-monitoring phase, and follow-up data ranging from 27 to 36 months are available 
for 12 of these patients. The remaining 2 patients being monitored for ongoing safety 
were lost to follow-up at 12 and 21 months.
The overall safety profile of the combination product from the available study data is
generally consistent with the known safety profile of ranibizumab as administered by ITV 
injection (ranibizumab USPI) and similar surgical procedures involving intraocular 
implants (Vitrasert USPI, 2013; Retisert USPI, 2013; Dunn et al. 2004; Gedde et al. 2012; 
Buys 2013). Procedure-related adverse events for the 20 Implant placements were not 
unexpected.  In 96 Implant refill procedures, the refill procedure-related adverse events
were comparable to adverse events related to ITV injections (see Section 5.1 for further 
details).
The improvement in best corrected visual acuity (BCVA) appeared comparable to 
monthly injections with sustained reduction in macular thickness and area of CNV 
leakage. The Phase I study provided evidence of the safety and tolerability of the 
combination product and supports the evaluation of RPDS in a Phase II study. It is 
expected that in the Phase II study the drug efficacy of the Implant treatment arms will 
be similar to the control ITV monthly injection treatment arm.

STUDY DESIGN
3.1
DESCRIPTION OF STUDY
Study GX28228 is a Phase II, multicenter, dose-ranging, randomized, active treatment 
(monthly ITV injection)controlled study to evaluate the efficacy, safety, and 
pharmacokinetics of ranibizumab delivered through the Implant using three ranibizumab 
formulation arms (10 mg/mL, 40 mg/mL, and 100 mg/mL) compared with the control arm 
(0.5-mg monthly ITV injections of 10-mg/mL formulation) in patients with nAMD.  The 
study will also evaluate the safety of the RPDS combination product.  Approximately 
220 patients at up to 60 sites in the United States will be randomized in a 3:3:3:2 ratio to 
four treatment arms within an approximate 24-month period of time (see Figure 2).

Patients randomized to the Implant treatment arms will have the Implant (pre-filled with 
ranibizumab) surgically inserted in the study eye at their Day 1 visit, after which they will 
be evaluated monthly for the need for an Implant refill, based upon protocol-specified 
refill criteria (see Section 3.1.1), for the remainder of the study treatment duration
(see Section 3.2).  Patients randomized to the ITV injection treatment arm (control) will 
be treated monthly with ITV injections of ranibizumab, starting at their Day 1 visit and 
continuing for the remainder of the study treatment duration (see Section 3.2).  The 
monthly ITV treatment arm patients will also be evaluated monthly according to the 
protocol-specified refill criteria (see Section 3.1.1), but will be treated monthly regardless 
of whether they meet the refill criteria.  Study visits will be conducted every 307 days 
relative to the Day 1 visit.
Following implementation of Protocol GX28228, Version 5, if warranted, enrollment and 
implant insertion surgeries may be paused to enable real-time review of post-implant 
insertion safety data by the Internal Monitoring Committee (IMC). In the case of such a 
pause, dosing will continue as per the protocol for patients who have already received 
study drug (e.g., patients who have performed Day 1 visit), while patients who have not 
yet received study drug will stay in Pre-Screening, Run-In, Screening, or Randomization
period (as applicable) and receive monthly open-label ITV ranibizumab treatment until 
enrollment and implant insertion surgeries are restarted.  In addition, in the case of a
pause, patients who have been randomized but have not yet received the study drug 
must repeat the Randomization assessments after enrollment and implant insertion 
surgeries have recommenced and before receiving the study drug.  Patients who exceed 
nine total anti-VEGF doses before receiving the study drug will no longer be eligible for
the study.  
The study will include screening and randomization visits followed by a treatment period.  
Baseline measurements will be taken at the randomization visit.  On the day of patient

Ranibizumab Port Delivery System—Genentech, Inc.
35/Protocol GX28228, Version 8
randomization, BCVA will be measured based upon the Early Treatment Diabetic 
Retinopathy Study (ETDRS) chart assessment at a starting test distance of 4 meters.
The patients will then be randomized to a treatment arm using a stratified randomization:  
BCVA score (65 letters vs. 66 letters) and number of prior anti-VEGF ITV injections 
(3 vs. 4). Patients must satisfy all eligibility criteria at both the screening and the 
randomization visits, including receipt of all screening visit images by a central reading 
center.  Historical OCT images taken at the time of diagnosis of nAMD will also be 
evaluated by the reading center to determine patient’s eligibility.  If fluorescein 
angiograms were taken at the time of diagnosis of nAMD, they must be submitted to the 
reading center as well. If available, historical fluorescein angiograms will be evaluated 
by the reading center, but are not required to determine patient’s eligibility at the 
screening visit.  As part of the screening process, the central reading center will evaluate 
the patient’s FA, FP, and SD-OCT images taken both at the time of diagnosis of nAMD 
and at the screening visit to provide an objective, masked assessment of patient 
eligibility regarding lesion CNV, lesion classification, total lesion size, area of CNV lesion, 
and CNV leakage (see the Reading Center manual for details).  Macular atrophy will 
also be evaluated at screening, using fundus autofluorescence (FAF) and SD-OCT 
measurements (see the reading center manual for further details). After all eligibility 
requirements are confirmed, patients will be randomized through an interactive 
voice/Web response system (IxRS) in a 3:3:3:2 ratio so that approximately 60 patients 
will receive the Implant filled with 10-mg/mL ranibizumab formulation, 60 patients will 
receive the Implant filled with 40-mg/mL ranibizumab formulation, 60 patients will receive 
the Implant filled with 100-mg/mL ranibizumab formulation, and 40 patients will receive 
monthly ITV injections of 10-mg/mL ranibizumab formulation (50 L for the 0.5-mg dose; 
see Figure 2). 
There are 4 patient eligibility scenarios based on prior anti-VEGF treatment history:
1.
Newly diagnosed nAMD patients who are treatment naïve. These patients will 
undergo pre-screening if they satisfy eligibility criteria and sign informed consent
(Table 2).  During the pre-screening, patients will receive two ranibizumab ITV 
treatments to determine if they demonstrate response to ranibizumab treatment as 
outlined per the eligibility criteria (see Section 4.1.1). 
2.
Patients diagnosed with nAMD in the study eye within 9 months prior to 
screening who have been treated with a single anti-VEGF ITV injection. These 
patients may receive one “run-in” ITV ranibizumab treatment prior to screening if 
they satisfy eligibility criteria and sign the informed consent form (see Table 2). 
3.
Patients diagnosed with nAMD in the study eye within 9 months prior to 
screening who have been treated with no more than eight anti-VEGF ITV 
injections and with the most recent dose being aflibercept or bevacizumab.  
These patients may receive one “run-in” ITV ranibizumab treatment prior to 
screening if they satisfy eligibility criteria and sign the informed consent form 
(see Table 2).

study on the day of their randomization visit and receive their Day 1 study treatment after 
conclusion of the Randomization visit.  If necessary, the Day 1 study treatment may be 
scheduled at a later date.  
Randomization visit cannot occur earlier than 28 days and no later than 37 days after the 
patient’s last ITV ranibizumab treatment.  
Day 1 study treatment visit cannot occur earlier than 28 days after and no later than 
37 days after the patient’s last ITV ranibizumab treatment, unless a patient randomized 
to the Implant arm needs more time to interrupt aspirin or NSAID usage 7 days before 
Day 1 (see Section 4.3.2.3).  For these patients, Day 1 study treatment visit must occur 
no later than 45 days after the patient’s last ITV ranibizumab treatment.
Patients who are randomized to the Implant treatment arms will have scheduled safety 
visit assessments on Day 2 (0), Day 7 (2 days), and Day 14 (2 days) after their 
Day 1 visit.  Starting at the Month 1 visit, the patients in the Implant treatment arms will 
be assessed monthly for the need for Implant refill with ranibizumab according to the

Ranibizumab Port Delivery System—Genentech, Inc.
37/Protocol GX28228, Version 8
protocol-specified refill criteria (see Section 3.1.1).  Their Implant will be refilled only if 
they meet re-treatment criteria.  The safety visits will be scheduled 7 (2) days after 
each refill (see Appendix 1).  After the Day 1 visit treatment, patients randomized to the
monthly ITV injection treatment arm will also be assessed monthly using the same 
re-treatment criteria as those for the Implant treatment arms (see Section 3.1.1) but will 
receive monthly ranibizumab injection treatment regardless of whether they meet the 
criteria (see Appendix 2 and Table 3).

a The Day 1 treatment in all treatment arms (Implant and ITV injection) will occur on such date 
so that no fewer than 28 days and no more than 37 days have elapsed from patient’s last 
study eye ranibizumab ITV treatment.
b Month X visits: After completion of the Month 9 visit, the study patients in the Implant arms 
will continue monthly evaluation for refill according to the Month X schedule of assessments 
(see Appendix 1) until the Sponsor decides, based on the primary analysis results, to either 
terminate the study and discontinue study treatment or offer patients entry into the RPDS 
Extension Study. The ITV arm patients will continue to be treated monthly according to the 
Month X schedule of assessments (see Appendix 2) until the Sponsor decides, based on the 
primary analysis results, to either terminate the study and discontinue study treatment, or 
offer patients entry into the RPDS Extension Study.
c Starting at the Month 1 visit, Implant treatment arms will receive a refill with ranibizumab only 
if protocol refill criteria are met (see Section 3.1.1).
d There will be safety assessment visits on Days 2, 7, and 14 after the Implant insertion and 
then 7 days after each Implant refill.  These safety assessment visits are not applicable to the 
ITV injections treatment arm.
e ITV injection arm patients will be treated monthly regardless of meeting the re-treatment 
criteria.
Starting at the Day 1 visit (ITV treatment arm) or starting at the Month 1 visit (Implant
arms), all patients will be contacted by site personnel 3 (1) days after each ITV 
injection or Implant refill to elicit reports of decrease in vision, eye pain, unusual redness, 
or any other new ocular symptoms in the study eye. Patients in the Implant treatment 
arms will also be asked to verify whether they have taken the prescribed, 
self-administered, post-injection antimicrobial treatments.  The ITV arm patients’ 
self-administered antimicrobial treatments will be prescribed at the investigator’s 
discretion.

Ranibizumab Port Delivery System—Genentech, Inc.
38/Protocol GX28228, Version 8
Only one eye will be selected as the study eye during the screening period. If both eyes 
are eligible, the investigator will determine, during the screening, which eye will be 
selected for study treatment (study eye).  

Should a non-study (fellow) eye require treatment for nAMD after randomization, 
treatment with ranibizumab is not recommended within 7 days of the study eye 
scheduled visit.  For patients in the Implant arms, if the fellow eye will be treated 
7 days after study eye treatment, ranibizumab should be administered after serum 
PK sample collection.  

The drug for the fellow eye during the study will be open-label ranibizumab and will 
be supplied by Genentech (see Section 4.3.1.4 for the drug formulation for the 
non-study eye). If a change in therapy is clinically indicated for the fellow eye per 
investigator judgment, the change must be discussed and agreed by the Medical 
Monitor prior to being made.  
All study patients will have scheduled monthly visits during the study.  After the Day 1
visit, patients randomized to the Implant treatment arms will be evaluated for their 
Implant refill at each monthly visit. Patients randomized to the ITV injection arm will be 
treated at each monthly visit. Study visits will be scheduled to occur according to the
schedule of assessments in Appendix 1 and Appendix 2 and have to be relative to the 
Day 1 (first study treatment) visit date until the patient completes the study.
Each potential study patient can be randomized into the study only once.
Please see Section 5.1.1.1 for the criteria to be used for dose interruption and 
treatment/study discontinuation.  Missed ranibizumab doses will not be replaced.
The ITV treatment arm patients who are discontinued from study treatment prematurely 
will be asked to undergo the scheduled monthly assessments until Last Patient In (LPI)
Month 9 visit, after which they will be scheduled 30 (7) days later for their final study 
visit.  The patients who are discontinuing study treatment from the Implant treatment 
arms will be scheduled, within 7 days after the treatment discontinuation decision is 
made, for Implant explantation followed by safety visits 1 and 7 (2) days 
post-explantation. Afterwards, they will be followed in the study, attending their monthly 
scheduled visits, until LPI Month 9 visit, after which they will be scheduled for the early 
termination visit (see Appendix 1).  As per investigator judgement, these patients may 
start an approved anti-VEGF for their AMD once the need for Implant explantation is 
confirmed and, preferably, after explantation is completed. All explanted Implants with 
their remaining content will be returned to the designee of the Sponsor for storage and 
potential future exploratory analysis (see Section 4.4). A vitreous or aqueous humor
sample will be collected at the start of explantation for patients undergoing an 
explantation procedure (see Appendix 19).

Ranibizumab Port Delivery System—Genentech, Inc.
39/Protocol GX28228, Version 8
Patients who withdraw from the study prior to scheduled study completion will be asked 
to return for an early termination evaluation 30 (7) days following their last study 
treatment for monitoring of adverse events and early termination visit assessments if 
they are in the ITV treatment arm. The patients who are discontinuing the study from the 
Implant treatment arms will be scheduled for Implant explantation within 7 days of the 
treatment discontinuation decision, followed by Safety Visits 1, 7 (2), 30 (7), and 60 
(7) days post-explantation after which they will be scheduled for the early termination 
visit 30 (7) days later. As per investigator judgment, these patients may start an 
approved anti-VEGF treatment for their AMD once the need for Implant explantation is 
confirmed and, preferably, after explantation is completed. All explanted Implants with 
remaining content will be returned to the designee of the Sponsor for storage and 
potential future exploratory analysis (see Section 4.4). A vitreous or aqueous humor
sample will be collected at the start of explantation for patients undergoing an 
explantation procedure (see Appendix 19).
Patients in the ITV injection arm will be evaluated monthly and will receive monthly 
study treatments (Day 1, Month 1 through Month X visit, see Appendix 2) until the 
Sponsor decides, based on the primary analysis results, to either terminate the study 
and discontinue study treatment, or offer patients entry into the RPDS Extension 
Study.  Their participation (excluding screening period) in the study will last
approximately 1338 months dependent on the date of their randomization to the study.  
The patients in the Implant arms will be evaluated monthly for the Implant refill 
(see Appendix 1) until the Sponsor decides, based on the primary analysis results, to 
either terminate the study and discontinue study treatment, or offer patients entry into 
the RPDS Extension Study. If a patient requires refills outside of the protocol-defined
visits window, the Medical Monitor must be contacted by the investigator.  Study 
participation for patients in the Implant arms (excluding screening period) is expected to 
last approximately 1338 months dependent on the date of their randomization to the 
study.
Study investigators will be qualified ophthalmologists, trained in the management of 
retinal diseases and ocular surgery and will be certified by a Sponsor-selected vendor to 
perform initial Implant fill, insertion, refill, and explantation.  The surgical procedures 
involved in the use of the investigational devices are also detailed in the IFU document.  
It is strongly preferred that a site has one investigator who evaluates and treats all 
patients with a backup investigator selected.  The site may opt to have two separate 
investigators but to maintain consistency in the evaluation and treatment of patients, it is 
strongly suggested that the same physician conduct the evaluation and treatment of a 
patient throughout the trial.
Study patients and all study site personnel will be masked to the Implant treatment arms’ 
ranibizumab formulation assignment (10 mg/mL vs. 40 mg/mL vs. 100 mg/mL) until the 
study’s conclusion (see Section 5.1.1.3 for more details on formulation assignment for 

Ranibizumab Port Delivery System—Genentech, Inc.
40/Protocol GX28228, Version 8
patients who meet lack of clinical efficacy criteria).  The Sponsor’s personnel directly 
involved in the study conduct (except prespecified IMC members) will be masked to the 
Implant treatment arms’ ranibizumab formulation assignment (10 mg/mL vs. 40 mg/mL 
vs. 100 mg/mL) until the time of primary analyses (see Section 5.1.1.3 for more details
on formulation assignment for patients who meet lack of clinical efficacy criteria).  The
IMC will closely monitor patient safety throughout the study (see Section 3.1.4).
Clinical pharmacology and PK scientists may be unmasked early for the purposes of 
interpreting emerging safety and efficacy data; those staff will not be part of the study 
team or have any interactions with sites or investigators.
In addition, the VA examiner will only conduct refraction and VA assessments and will be 
masked to patient study eye assignment and patient treatment assignment.  The VA 
examiner will have no access to patient VA scores from previous visits, and will be only 
aware of the patient’s refraction data from previous visits.  The VA examiner may 
perform no other direct patient-care tasks.  Patients will be asked not to discuss their 
study eye assignment (right vs. left) with the VA examiner.  
3.1.1
Refill/Re-Treatment Criteria
Starting at the Month 1 visit, all randomized patients will be assessed monthly for the 
refill/re-treatment.  The patients randomized to the ITV injection arm will be treated 
monthly, regardless of whether they meet re-treatment criteria.  The patients randomized 
to the Implant treatment arms will have their Implant refilled only if any of the following 
criteria is met, as automatically determined by contacting IxRS:  

Increase in CFT of 75 µm on SD-OCT at the current visit compared with the 
average CFT over the last 2 available measurements, due to nAMD disease activity 
OR

Increase in CFT of 100 m from the lowest CFT measurement on study, due to 
nAMD disease activity 
OR

Decrease of 5 letters in BCVA at the current visit compared with the average 
BCVA over the last two available measurements, due to nAMD disease activity 
OR

Decrease of 10 letters from best recorded BCVA on study, due to nAMD disease 
activity 
OR

Presence of new macular hemorrhage, due to nAMD disease activity

Ranibizumab Port Delivery System—Genentech, Inc.
41/Protocol GX28228, Version 8
Note: To assess the need for refill at 1 month after initial fill, please utilize the following 
criteria:

Decrease of 10 letters in BCVA at the current visit compared with the baseline 
BCVA, due to nAMD disease activity
OR

Increase in CFT of 100 m at the current visit compared with the baseline CFT, 
due to nAMD disease activity
OR

Presence of new macular hemorrhage, due to nAMD disease activity
Patients assigned to the Implant treatment arms will be scheduled for a safety evaluation 
visit 7 (2) days after each refill.
The schedules of study assessments are provided in Appendix 1 and Appendix 2. 
3.1.2
Pharmacokinetic Evaluation
The objective of the PK analysis is to characterize the Implant sustained-delivery 
performance by characterizing the serum and optional aqueous humor concentrations 
(see Appendix 1 for details) of 10-mg/mL, 40-mg/mL, and 100-mg/mL formulations of 
ranibizumab delivered via the Implant.  PK parameters of interest will be estimated after 
implant and at subsequent refills using noncompartmental analysis (NCA) and/or a 
population PK model as appropriate; parameters will include area under the 
concentrationtime curve (AUC), maximum serum concentration (Cmax) observed, time to 
maximum concentration (tmax), steady-state serum concentration at the end of a dosing 
interval (Ctrough [predose]), and terminal half-life (t1/2).  
The population PK model couples the in-vitro release parameters of the Implant with the 
population pharmacokinetics of ranibizumab in AMD patients to describe the 
pharmacokinetics of ranibizumab in AMD patients receiving these Implants. Inter-patient 
variability will be assessed. Coefficient of variation (%CV) of serum concentration at 
each PK sampling time point will be reported.  The observed serum pharmacokinetics
will be compared to the expected PK profiles as predicted by a population PK model.
3.1.3
Planned Total Sample Size
The study will randomize approximately 220 patients, 60 per each of three Implant
treatment arms and 40 to the ITV injection arm (up to 60 sites). For further details 
see Section 6.1.

Ranibizumab Port Delivery System—Genentech, Inc.
42/Protocol GX28228, Version 8
3.1.4
Internal Monitoring Committee
Ongoing review of study data (including adverse events of special interest [AESIs], 
serious adverse events, adverse device effects [ADEs], and laboratory abnormalities) 
will be performed by the IMC. The IMC roles and responsibilities will be outlined in the 
IMC Agreement.
3.2
LENGTH OF STUDY
The completion of study treatment for all patients is defined as the date when the 
Sponsor makes the decision, based on the primary analysis results, to either terminate 
the study and discontinue study treatment, or offer patients entry into the RPDS 
Extension Study.  The primary analyses data is expected to be available approximately 
4 months after the Month 9 visit of the last patient randomized.
The length of the study is approximately 38 months.
3.3
END OF STUDY
The end of the study is defined as the date when the last patient, last study visit occurs.
3.4
RATIONALE FOR STUDY DESIGN
3.4.1
Rationale for Ranibizumab Dose Selection
Delivery of ranibizumab via the Implant was chosen to investigate an alternate dosing 
method.  Sustained release of ranibizumab from the Implant is an alternate dosing 
method that may result in less-frequent need of re-treatment than monthly dosing with 
ITV injections. It has the potential to reduce the number of patient visits, as well as the 
burden on patients, caregivers, and healthcare providers.  In addition, increased 
treatment compliance and optimum visual outcomes may result from the sustained 
delivery of ranibizumab through the Implant.
The three ranibizumab formulations administered via the Implant will be evaluated 
monthly to determine the efficacy and safety of each formulation.  Based on the fill 
volume of 20 L of the Implant, the maximum amount of ranibizumab with which the 
Implant can be initially filled and subsequently refilled is approximately 0.2 mg for the 
10-mg/mL formulation, 0.8 mg for the 40-mg/mL formulation, and 2 mg of ranibizumab 
for 100-mg/mL formulation.  The selection of the proposed Phase II doses was 
determined by several factors.  The selected doses are anticipated to maintain 
ranibizumab vitreous trough concentrations either below (10-mg/mL), at (40-mg/mL), or 
above (100-mg/mL) the vitreous drug levels estimated to be correlated with efficacy 
(12 g/mL), as assessed from pivotal studies that administered monthly 0.5-mg ITV 
injections.  Thus, the three dose levels may provide a range of exposures to assess the 
dose- and exposure-response relationships.  If the doses do not differentiate 
substantially on efficacy, as a result of potentially frequent refills for lower doses 
according to the “as needed” protocol defined refill criteria, then the treatment arms are 
expected to differentiate on the basis of time to first meeting refill criteria and number of 

Ranibizumab Port Delivery System—Genentech, Inc.
43/Protocol GX28228, Version 8
refills over the course of the study.  In addition, all doses were selected taking into 
account prior clinical experience to ensure patient safety.
3.4.2
Rationale for Pharmacokinetic Evaluation Schedule
The serum pharmacokinetics of ranibizumab following ITV administration have been well 
characterized, however the PK profile for sustained delivery is expected to be markedly 
different.  In order to characterize the PK profile and the in vivo sustained delivery of 
ranibizumab via the Implant, serum PK samples will be collected from patients in the 
Implant treatment arms at multiple timepoints (see Appendix 1) before and after refills.  
The sampling timepoints are expected to be sufficient to estimate key PK parameters of 
interest (see Section 3.1.2) following initial insertion of the ranibizumab-filled Implant and 
subsequent refills, and to demonstrate sustained exposure to ranibizumab.  An optional 
aqueous humor sample (collected prior to or immediately following Implant refills), and a 
vitreous or aqueous humor sample (collected at the start of explantation for patients 
undergoing an explantation procedure), will also be collected to further characterize 
Implant kinetics and relate serum to vitreous ranibizumab concentrations.  For additional 
details on ITV ranibizumab pharmacokinetics, refer to the RPDS IB.  
3.4.3
Rationale for Patient Population
Ranibizumab has been shown to be effective in preventing or reducing vision loss in 
patients with nAMD; therefore, this patient population was selected to be the first in 
which the RPDS would be evaluated. The goal is to demonstrate a treatment approach 
that maintains the efficacy seen with monthly ITV injections while reducing the number of 
ITV injections and monitoring visits. Other indications (diabetic macular edema, retinal 
vein occlusion) may also benefit but would be considered for investigation following the
Phase II study results in nAMD.
3.4.4
Rationale for Control Group
Ranibizumab is an approved treatment for nAMD in the European Union, United States,
and many other countries worldwide.  The monthly dosing of 0.5 mg (10-mg/mL) of ITV 
ranibizumab is the approved posology in the United States and was selected as the 
appropriate control group based on discussions with both the FDA and European 
Medicines Agency.  Therefore, patients in the control arm in the randomized phase of 
the study will be treated with monthly ITV injections of 0.5-mg dose of ranibizumab.
3.5
OUTCOME MEASURES

MATERIALS AND METHODS
4.1
PATIENTS
Patients with subfoveal neovascularization secondary to AMD diagnosed within 
9 months and treated with ITV anti-VEGF agents will be enrolled in the study.  Written 
informed consent will be obtained before initiation of any study-related procedures.  A 
patient’s screening visit should occur no sooner than 7 days following administration of 
the last ITV ranibizumab treatment to the study eye.  The screening visit will be followed 
by the randomization visit.  
The first study treatment (Day 1) may occur at the conclusion of the randomization visit 
for the ITV treatment arm; the Implant arm patients may have these two visits separated 
due to the systemic medication wash out period (see note below) and the surgery room 
availability.  Randomization visit and Day 1 study treatment visit must occur on a date 
such that no less than 28 days and no more than 37 days have elapsed from the
patient’s last study eye ITV ranibizumab treatment.

46/Protocol GX28228, Version 8
There are 4 patient eligibility scenarios based on prior anti-VEGF treatment history.
1.
Newly diagnosed nAMD patients who are treatment naïve. These patients will 
undergo pre-screening if they satisfy eligibility criteria and sign informed consent
(Table 2). During the pre-screening, patients will receive two ranibizumab ITV 
treatments to determine if they demonstrate response to ranibizumab treatment as 
outlined per the eligibility criteria (see Section 4.1.1).  
2.
Patients diagnosed with nAMD in the study eye within 9 months prior to 
screening who have been treated with a single anti-VEGF ITV injection. These 
patients may receive one run-in ITV ranibizumab treatment prior to screening if they 
satisfy eligibility criteria and sign the informed consent form (see Table 2).
3.
Patients diagnosed with nAMD in the study eye within 9 months prior to 
screening who have been treated with no more than eight anti-VEGF ITV 
injections and with the most recent dose being aflibercept or bevacizumab.  
These patients may receive one run-in ITV ranibizumab treatment prior to screening 
if they satisfy eligibility criteria and sign the informed consent form (see Table 2).
4.
Patients diagnosed with nAMD in the study eye within 96 months prior to 
screening who have been treated with no more than nine anti-VEGF ITV 
injections and with the most recent dose being ranibizumab.  These patients
can proceed directly to screening (see Table 2).

4.2
METHOD OF TREATMENT ASSIGNMENT AND MASKING
4.2.1
Randomization and Masking
Patients will be randomized through an IxRS in a 3:3:3:2 ratio so that approximately 
60 patients will receive the Implant with 10-mg/mL ranibizumab formulation, 60 patients 
will receive the Implant with 40-mg/mL ranibizumab formulation, 60 patients will receive 
the Implant with 100-mg/mL ranibizumab formulation, and 40 patients will receive 
monthly ITV injections of 10-mg/mL ranibizumab formulation. On the day of patient 
randomization visit, BCVA will be measured based upon the ETDRS chart assessment 
at a starting test distance of 4 meters, and randomization will be stratified by the BCVA 
score (65 letters vs. 66 letters) and number of prior anti-VEGF injections (3 vs 4).
Study patients and all study site personnel will be masked to the Implant treatment arms’ 
ranibizumab formulation assignment (10 mg/mL vs. 40 mg/mL vs. 100 mg/mL) until the 
study’s conclusion (see Section 5.1.1.3 for more details on formulation assignment for 
patients who meet lack of clinical efficacy criteria).  The Sponsor’s personnel directly 

Ranibizumab Port Delivery System—Genentech, Inc.
53/Protocol GX28228, Version 8
involved in the study conduct (except prespecified IMC members) will also be masked to 
the Implant treatment arms’ ranibizumab formulation assignment (10 mg/mL vs. 
40 mg/mL vs. 100 mg/mL) until unblinding of treatment code after database lock
(see Section 5.1.1.3 for more details on formulation assignment for patients who meet 
lack of clinical efficacy criteria).  In addition, the VA examiner will conduct only refraction, 
BCVA assessment, BCVA assessment under low luminance conditions, and will be 
masked to patient study eye assignment and patient treatment assignment.  The VA 
examiner will have no access to the BCVA scores of a patient’s previous visits, and will 
be only aware of the patient’s refraction data from previous visits.  The VA examiner may 
provide no other direct patient care.  Patients will be asked not to discuss their study eye 
assignment with the VA examiner.
Patients and study site personnel will not be masked with regard to patient assignment 
to the ITV arm or an Implant arm because of the difficulties of maintaining masking 
following the surgical procedure, the additional safety visits applicable only to the Implant 
arms, and Implant visualization upon ophthalmic examination.
4.2.2
Unmasking Procedure
Treatment assignment should be unmasked for a patient in an Implant treatment arm in 
the event of a life-threatening medical emergency (if the investigator considers this 
necessary for treatment of the patient) that requires immediate unmasking or in the 
event of an unexpected serious adverse events judged by the investigator as related to 
study drug or RPDS, for FDA safety reporting.  In such cases, unmasking will be 
implemented following standard procedures.

Implant
Please see the RPDS IFU document for a detailed description of the Implant initial fill, 
insertion, refill, and explantation procedures.
4.3.2.2
Dosage
Patients in the Implant Treatment Arms
Patients will have the Implant (prefilled with approximately 20 L of either the 10-mg/mL 
(approximately 0.2 mg dose), 40-mg/mL (approximately 0.8 mg dose), or 100-mg/mL 
formulation (approximately 2-mg dose) of ranibizumab) surgically inserted in the study 
eye at the Day 1 visit following their randomization visit.  Starting at the Month 1 visit, 
patients will be evaluated monthly for the need for Implant refill with the10-mg/mL, 
40-mg/mL, or 100-mg/mL formulations of ranibizumab according to their randomization
as per protocol-specified refill criteria (see Section 3.1.1).  If the criteria are not met, no
Implant refill will be given. At each refill, a volume of approximately 100 L of 
ranibizumab will be injected in situ into the Implant through the septum to exchange the
remaining contents of the Implant with newly introduced ranibizumab.  During the refill 
procedure, the contents of the Implant will be collected in the fluid collection reservoir of 

Ranibizumab Port Delivery System—Genentech, Inc.
55/Protocol GX28228, Version 8
the Refill Needle, if applicable (see the RPDS IFU for further details). The volume of 
newly introduced ranibizumab remaining in the Implant after the refill procedure will be 
approximately 20 L.  After the initial fill of the Implant with ranibizumab, patients will be 
evaluated for their Implant refill according to protocol-specified refill criteria 
(see Section 3.1.1) at each of their scheduled visits until the study treatment completion 
(see Section 3.2 for the definition).  Missed treatments will not be made up.
If a study patient meets criteria for lack of clinical efficacy, he or she will receive a rescue 
injection with open-label ranibizumab.  After that, he or she will receive the 100-mg/mL 
formulation for all future refills (see Section 5.1.1.3 for more details).
Study visits for the Implant treatment arms will be scheduled to occur according to the 
schedule in Appendix 1 and have to be relative to the Day 1 (the first study treatment) 
visit date until patients complete the study.
Patients in the ITV Injection Treatment (Control) Arm
Patients will receive their first ITV injection of 50 L of the 10-mg/mL ranibizumab 
(0.5 mg dose) formulation at the Day 1 visit, which may occur (if feasible) at the 
conclusion of the randomization visit.  Afterwards, patients will receive monthly ITV 
injections of 50 L of 10-mg/mL formulation.  Patients will be receiving the study 
treatment at each scheduled monthly visit until the study treatment completion (see
Section 3.2 for the definition).  Missed treatments will not be made up.
Study visits for the ITV treatment arm will be scheduled to occur according to the 
schedule in Appendix 2 and have to be relative to the Day 1 (the first study treatment) 
visit date until patients complete the study.
Ranibizumab dosing should not occur earlier than 22 days after the previous dosing.  
Guidelines for treatment interruption or discontinuation are provided in Section 5.1.1.1
and Table 6.
Pre-Screening
Pre-screening is available for newly diagnosed nAMD patients who are treatment naïve 
in the study eye.  Patients eligible for the pre-screening will receive their first ITV 
injection of 50 L of the 10-mg/mL ranibizumab (0.5 mg dose) formulation at the 
Pre-Screening visit 1, and their second injection 307 days later (Pre-Screening visit 2).  
A third pre-screening treatment may be allowed after consultation with the Medical 
Monitor.  Afterwards, patients will undergo the screening visit, which will occur at least 
7 days following administration of the last pre-screening ITV ranibizumab treatment to 
the study eye (see Appendix 3).

prior to screening who have been treated with a single anti-VEGF ITV injection, or with 
no more than eight anti-VEGF ITV injections and with the most recent dose being 
aflibercept or bevacizumab.  Patients eligible for the run-in treatment will receive their 
single ITV injection of 50 L of the 10 mg/mL ranibizumab (0.5 mg dose) formulation in 
the study eye at the time of consent.  In exceptional cases, a second run-in treatment 
may be allowed after consultation with the Medical Monitor.  Afterwards, patients will 
undergo the screening visit, which will occur at least 7 days following administration of 
the run-in ITV ranibizumab treatment to the study eye (see Appendix 4).
4.3.2.3
Administration
Implant Treatment Arms
Prior to Implant insertion or explantation, patients will be required to verify that they have 
self-administered antimicrobial eye drops to the study eye 4 times within the previous 
24 hours.  As per investigator’s discretion, patients may also be required to have 
self-administered antimicrobial eye drops to the study eye 4 times within the 24 hours
prior to potential Implant refills.
All patients must be instructed to self-administer antimicrobial eye drops to the study eye 
4 times daily for 3 days following any refills.  Antimicrobial eye drops to the study eye will 
also be required 4 times daily for 7 days following Implant insertion and explantation.
All patients randomized to the Implant arm and receiving ongoing aspirin or NSAID 
treatment must interrupt aspirin or NSAID treatment 7 days prior to Implant insertion or 
explantation and until at least the Day 2 safety visit following the procedure.
Prior to and during the Implant insertion procedure, blood pressure must be controlled. 
Before surgery, blood pressure must be checked after the patient has been in a resting 
state (i.e., supine or sitting) for at least 15 minutes. If blood pressure exceeds the 
recommended levels (i.e., between 100/60 mmHg and 155/95 mmHg), the Implant 
insertion surgery must be rescheduled.
Patients in the Implant treatment arms will have the Implant, prefilled with ranibizumab,
surgically inserted into the study eye at the Day 1 visit and subsequently refilled at 
monthly visits only if the protocol-specified refill criteria are fulfilled (see Section 3.1.1).  
The insertion and explantation procedures must be performed in the surgery room while 
the refill procedure is permitted in the physician office setting.  For detailed instructions 
on the Implant initial fill, insertion, refill, and explantation procedures, refer to the 
RPDS IFU.

potential future analysis.  A method to retrieve the contents from explanted Implants is in 
place and protocols to characterize drug product are under development.  In addition, 
the explanted Implants may undergo physical inspection and/or functional testing.
4.4.1.2
Ancillary Devices
The Initial Fill Needle, Insertion Tool, Refill Needle, and Explant Tool must be returned to 
the Sponsor or Sponsor’s designee for possible physical inspection and/or functional 
testing.
4.4.2
Continued Access to RPDS
Currently, the Sponsor does not plan to provide ranibizumab via Implant or via ITV 
injections or to provide other study interventions to patients after the conclusion of the 
study or following early patient withdrawal.  The Sponsor will evaluate the 
appropriateness of continuing to provide ranibizumab treatment to Implant treatment 
arms patients after evaluating RPDS efficacy, safety, and PK data gathered in the study.
Depending on the results of the study, the Sponsor may offer study patients in the 
Implant arms entry into a separate RPDS Extension Study to continue to provide 
ranibizumab via the Implant in an open-label manner.  If the results from this trial do not 
warrant further investigation of the RPDS, all patients in the Implant arms will have their 
Implants explanted.
4.5
CONCOMITANT THERAPY
4.5.1
Permitted Therapy 
Concomitant medications are any prescription drugs or over-the-counter preparations 
other than protocol-specified procedural medications (e.g., dilating drops, fluorescein 
dyes, cefazolin or vancomycin, or medications associated with Implant insertion, refill,
and extraction procedures) and pre- and poststudy treatment medications (e.g., 
proparacaine, antimicrobials, steroids) used by a patient within 7 days preceding the 
randomization visit until conclusion of the patient’s study participation or early 
termination visit.
Patients who use other maintenance therapy should continue its use unless prohibited 
as indicated in Section 4.5.2.  All concomitant medications should be reported to the 
investigator and recorded on the appropriate eCRF:

Following randomization, if a patient’s fellow eye requires treatment for nAMD, 
treatment with ITV ranibizumab injection may be administered at the discretion of 
the evaluating investigator. If a change in therapy is clinically indicated for the fellow 
eye per investigator judgment, the change must be discussed and agreed with the 
Medical Monitor prior to being made.  

All patients randomized to the Implant arm and receiving ongoing aspirin or NSAID 
treatment must interrupt aspirin or NSAID treatment 7 days prior to implant insertion 
or explantation. These medications can be restarted, if appropriate, after the Day 2
safety visit.

4.6.7
Patient-Reported Outcome
The MacTSQ must be administered to patients by an interviewer (for patients who speak 
English or Spanish by site personnel other than the VA examiner), before the patient 
completes any other study visit procedures (see Appendix 19).
The MacTSQ is a 14-item questionnaire designed to assess treatment satisfaction in 
patients with AMD. Scoring of the MacTSQ results in two subscale scores (information 
provision and convenience; impact of treatment) and a total score.  Subscale scores 
range from 0 to 36 and total scores range from 0 to 72.  A higher score indicates greater 
satisfaction.
Two versions of the questionnaire will be used, differing only in recall period.  At 
randomization the questionnaire will refer to “since diagnosis”.  For interim assessments 
at Months 1, 6, and 9, and at the final/early termination visits, the questionnaire will refer 
to “since you enrolled in this study”.
4.6.8
Video Capturing of Implant Insertion, Refill, and Explantation 
Procedures
The Implant insertion and explantation procedures will be captured on video for 
Investigators training purposes unless the study center has policies in place that prohibit 
these procedures being video captured. The Implant refill procedure video capture is 
optional.
4.6.9
Exploratory Substudies
The Sponsor may propose exploratory substudies associated with the Study GX28228 
protocol.  Each substudy will be documented in a separate substudy protocol and 
associated ICF(s).
4.6.10
Timing of Study Assessments
4.6.10.1
Screening and Pretreatment Assessments
The study will randomize approximately 220 patients and will be performed at up to 
60 sites in the United States.  Written informed consent for participation in the study 
must be obtained before performing any study-specific screening tests or evaluations.  
Informed Consent Forms (ICFs) for all screened patients, including those who are not 
subsequently randomized, will be maintained at the study site.
Screening Visit
Screening visit assessments cannot be performed sooner than 7 days following 
administration of the last ITV ranibizumab treatment to the study eye. After a patient has 
signed the ICF, the site will contact IxRS for the patient’s screening number assignment.  
All screening visit evaluations must be completed and reviewed to confirm that patients 

Ranibizumab Port Delivery System—Genentech, Inc.
67/Protocol GX28228, Version 8
meet all eligibility criteria before they are scheduled for their randomization visit.
Screening visit assessments may be performed on multiple days. 
Note:  If a patient fails screening assessments, he or she may be re-screened once if 
deemed appropriate by the investigator.  A new screening number will be assigned to 
the patient through the IxRS. The investigator will maintain a screening log to record 
details of all patients screened and to confirm eligibility or record reasons for screening 
failure, as applicable.
For the schedule of screening assessments, refer to the schedule of assessments in
Appendix 1 and Appendix 2. 
Randomization Visit and Day 1 Treatment
The randomization visit and the Day 1 treatment can occur on the same day for ITV 
treatment arm patients; the Implant arm patients may have these two visits separated 
due to the medication washout period (see Section 4.1) and the surgery room availability.
However, for all study patients, the Randomization visit and Day 1 study treatment must 
occur between 28 days and 37 days after the patient’s last study eye ITV ranibizumab 
treatment.  Unless noted otherwise, all procedures and assessments should be 
performed prior to contacting IxRS for the patient’s randomization number assignment 
and prior to the first study treatment administration to confirm that the patient is still 
eligible to be randomized to the study.  All randomization study visit assessments must 
be performed on the same day.  A patient can only be randomized to the study once.
When a patient has satisfied all eligibility criteria at both the screening and the 
randomization visit, including the receipt and evaluation of historical and screening visit 
images by the central reading center, the patient will be assigned a randomization
number (a number different from the patient’s screening number) by the IxRS and will be 
randomized to one of the treatment arms.  It is recommended that the patients 
randomized to the ITV-injection arm receive their Day 1 study treatment on the day of 
randomization, while patients randomized to the Implant treatment arms may be 
scheduled for their Day 1, Implant surgical insertion visit later.  If the Day 1 study 
treatment for Implant arms cannot be completed within the visit window after 
randomization, an additional ITV ranibizumab treatment may be required.
Please see the schedule of assessments provided in Appendix 1 and Appendix 2 for the 
schedule of randomization and Day 1 visit assessments. 
Study visits will be scheduled to occur according to the schedule in Appendix 1 and 
Appendix 2 and have to be relative to the Day 1 (first study treatment) visit date until 
patients complete the study or the study is terminated early.

Ranibizumab Port Delivery System—Genentech, Inc.
68/Protocol GX28228, Version 8
Pre-Screening (if applicable)
Pre-screening is available for newly diagnosed nAMD patients who are treatment naïve 
in the study eye.  After a patient has signed the informed consent form, the site will 
contact IxRS for the patient’s pre-screening number assignment.  A patient may only 
participate once in the pre-screening.  For the schedule of assessments in the pre-
screening, refer to Appendix 3.
Run-In (if applicable)
“Run-in” is available for patients diagnosed with nAMD in the study eye within 9 months 
prior to screening who have been treated with a single anti-VEGF ITV injection, or with 
no more than eight anti-VEGF ITV injections and with the most recent dose being 
aflibercept or bevacizumab.  After a patient has signed the informed consent form, the 
site will contact IxRS for the patient’s number assignment.  A PK sample will be collected 
prior to receipt of the “run-in” ranibizumab ITV treatment.  For the schedule of 
assessments in the “run-in”, refer to Appendix 4.
4.6.10.2
Assessments during Treatment
All assessments must be performed on the day of the specified visit, unless a time 
window is specified in the schedule of assessments (see Appendix 1 and Appendix 2).  
Assessments scheduled on the day of study treatment administration should be 
performed prior to administration of study treatment, unless otherwise noted in the 
schedule of assessments.  The MacTSQ assessment should be administered prior to 
the completion of other study assessments.
Please see Appendix 1 and Appendix 2 for the schedule of assessments performed
during the treatment period.
Study visits will be scheduled according to the schedule in Appendix 1 and Appendix 2
and have to be relative to the Day 1 (first study treatment) visit date until patients 
complete or are early terminated from the study.  Ranibizumab dosing should occur no 
earlier than 22 days following the previous dosing.
4.6.10.3
Assessments at Early Study Treatment Discontinuation
The ITV treatment arm patients who are discontinued from study treatment prematurely 
will be asked to undergo the scheduled monthly visits until the LPI Month 9 visit, after 
which they will be scheduled for their final study visit 30 (7) days later.  The patients 
who are discontinuing study treatment from the Implant treatment arms will be scheduled, 
within 7 days after the treatment discontinuation decision is made, for Implant 
explantation followed by safety visits 1 and 7 (2) days post-explantation.  Afterwards 
they will be followed in the study, attending their monthly scheduled visits, until LPI
Month 9 visit, after which they will be scheduled for the early termination visit (see 
Appendix 1).  As per investigator judgement, these patients may start an approved 
anti-VEGF for their AMD once the need for Implant explantation is confirmed and, 
preferably, after explantation is completed.  All explanted Implants, with remaining 

Ranibizumab Port Delivery System—Genentech, Inc.
69/Protocol GX28228, Version 8
content, will be returned to the designee of the Sponsor for storage and potential future 
exploratory analysis (see Section 4.4).  A vitreous or aqueous humor sample will be 
collected at the start of explantation for patients undergoing an explantation procedure
(see Appendix 20).
4.6.10.4
Assessments at Early Study Discontinuation
Patients withdrawing from the study early should return for an early termination 
evaluation 30 (7) days following the last study drug treatment for monitoring of all 
adverse events (serious and non-serious), as well as for early termination assessments
if they are in the ITV treatment arm. The patients who are discontinuing the study from 
the Implant treatment arms will be scheduled for Implant explantation within 7 days of 
the study discontinuation decision.  This will be followed by Safety Visits 1, 7 (2), 
30 (7), and 60 (7) days post-explantation, after which they will be scheduled for the
early termination visit 30 (7) days later.  As per investigator judgment, these patients 
may start an approved anti-VEGF treatment for their AMD once the need for Implant 
explantation is confirmed and, preferably, after explantation is completed.  All explanted
Implants, with remaining content, will be returned to the designee of the Sponsor for 
storage and potential future exploratory analysis (see Section 4.4).  A vitreous or 
aqueous humor sample will be collected at the start of explantation for patients 
undergoing an explantation procedure (see Appendix 20).
4.6.10.5
Assessment at Study Completion
Study completion is defined as a patient completing the final study visit assessments.  
Please see Appendix 1 and Appendix 2 for the schedule of assessments performed at 
the final/early termination visit.
Patients in the ITV treatment arm will return for the final study visit evaluation 30 (7) 
days following the last study drug treatment for monitoring of all adverse events (serious 
and non-serious), as well as for final study visit assessments, unless they enter into the 
RPDS Extension Study (Section 4.4.2).
Patients in the Implant arms who complete the study will be scheduled for the Implant
explantation 30 (7) days following the last refill (if applicable), unless they enter into the 
RPDS Extension Study (Section 4.4.2). Explantation will be followed by Safety Visits 1, 
7 (2), 30 (7), and 60 (7) days post-explantation, after which patients will be 
scheduled for the final study visit 30 (7) days later. As per investigator judgment, these 
patients may start an approved anti-VEGF treatment for their AMD once the need for 
Implant explantation is confirmed and, preferably, after explantation is completed. All 
explanted Implants, with remaining content, will be returned to the designee of the 
Sponsor for storage and potential future exploratory analysis (see Section 4.4).  A 
vitreous or aqueous humor sample will be collected at the start of explantation for 
patients undergoing an explantation procedure (see Appendix 20).

Ranibizumab Port Delivery System—Genentech, Inc.
70/Protocol GX28228, Version 8
4.6.10.6

outlined in Sections 5.5 and 5.6.
4.6.10.7
Assessments at Unscheduled Visits 
Refer to Appendix 5 for unscheduled safety assessments that can be utilized for all 
study patients.  All listed assessments are to be performed if determined to be 
necessary by the investigator.
4.6.11
Refill Needle Sample Collection
The following samples will be collected from patients in the Implant treatment arms and 
may be analyzed by the Sponsor or selected designee:

Residual content of the Implant present in the Refill Needle may be collected during 
refill procedure (if applicable) to evaluate the possible association of vitreous or 
aqueous humor biomarkers with disease characteristics and response to 
ranibizumab.  
4.6.12
Samples for Roche Clinical Repository
4.6.12.1
Overview of the Roche Clinical Repository
The Roche Clinical Repository (RCR) is a centrally administered group of facilities used 
for the long-term storage of human biologic specimens, including body fluids, solid 
tissues, and derivatives thereof (e.g., DNA, RNA, proteins, peptides).  The collection and 
analysis of RCR specimens will facilitate the rational design of new pharmaceutical 
agents and the development of diagnostic tests, which may allow for individualized drug 
therapy for patients in the future.
Specimens for the RCR will be collected from patients who give specific consent to 
participate in this optional research.  RCR specimens will be used to achieve the 
following objectives:

To study the association of biomarkers with efficacy, adverse events, or disease 
progression

To increase knowledge and understanding of disease biology

To study drug response, including drug effects and the processes of drug absorption 
and disposition

To develop, validate, and characterize biomarker, diagnostic, pharmacokinetic, or 
anti-therapeutic antibody assays and establish the performance characteristics of 
these assays
4.6.12.2
Approval by the Institutional Review Board or Ethics 
Committee
Collection and submission of biological samples to the RCR is contingent upon the 
review and approval of the exploratory research and the RCR portion of the Informed 
Consent Form by each site's Institutional Review Board or Ethics Committee (IRB/EC) 

Ranibizumab Port Delivery System—Genentech, Inc.
71/Protocol GX28228, Version 8
and, if applicable, an appropriate regulatory body.  If a site has not been granted 
approval for RCR sampling, this section of the protocol (Section 4.6.12) will not be 
applicable at that site.
4.6.12.3
Sample Collection
The following RCR samples will be collected for research purposes, including but not 
limited to research on dynamic (non-inherited) biomarkers related to Ranibizumab mode 
of action, VEGF biology, AMD biology, and/or related diseases biology:

Serum samples at the Randomization Visit and Visits at Month 4 and Month 9, for 
the evaluation of circulating biomarkers.

Plasma samples at the Randomization Visit and Visits at Month 4 and Month 9, for 
the evaluation of circulating biomarkers.
The following RCR samples will be collected for research purposes, including but not 
limited to research on genetic (inherited) biomarkers related to Ranibizumab mode of 
action, VEGF biology, AMD biology and/or related diseases biology:

Whole blood for DNA extraction at the Randomization Visit
For all samples, dates of consent and specimen collection should be recorded on the 
associated RCR page of the eCRF.  For sampling procedures, storage conditions, and 
shipment instructions, see the laboratory manual.  
RCR specimens will be destroyed no later than 15 years after the date of final closure of 
the associated clinical database.  The RCR storage period will be in accordance with the 
IRB/EC approved Informed Consent Form and applicable laws (e.g., health authority 
requirements).
The dynamic biomarker specimens will be subject to the confidentiality standards 
described in Section 8.4.  The genetic biomarker specimens will undergo additional 
processes to ensure confidentiality, as described below.  
4.6.12.4
Confidentiality
Given the sensitive nature of genetic data, Roche has implemented additional processes 
to ensure patient confidentiality for RCR specimens and associated data.  Upon receipt 
by the RCR, each specimen is "double-coded" by replacing the patient identification 
number with a new independent number.  Data generated from the use of these 
specimens and all clinical data transferred from the clinical database and considered 
relevant are also labeled with this same independent number.  A "linking key" between 
the patient identification number and this new independent number is stored in a secure 
database system.  Access to the linking key is restricted to authorized individuals and is 
monitored by audit trail.  Legitimate operational reasons for accessing the linking key are 
documented in a standard operating procedure.  Access to the linking key for any other 
reason requires written approval from the Pharma Repository Governance Committee 
and Roche's Legal Department, as applicable.

Ranibizumab Port Delivery System—Genentech, Inc.
72/Protocol GX28228, Version 8
Data generated from RCR specimens must be available for inspection upon request by 
representatives of national and local health authorities, and Roche monitors, 
representatives, and collaborators, as appropriate.
Patient medical information associated with RCR specimens is confidential and may be 
disclosed to third parties only as permitted by the Informed Consent Form (or separate 
authorization for use and disclosure of personal health information) signed by the patient, 
unless permitted or required by law.
Data derived from RCR specimen analysis on individual patients will generally not be 
provided to study investigators unless a request for research use is granted.  The 
aggregate results of any research conducted using RCR specimens will be available in 
accordance with the effective Roche policy on study data publication.
Any inventions and resulting patents, improvements, and/or know-how originating from 
the use of the RCR data will become and remain the exclusive and unburdened property 
of Roche, except where agreed otherwise.
4.6.12.5
Consent to Participate in the Roche Clinical Repository
The Informed Consent Form will contain a separate section that addresses participation 
in the RCR.  The investigator or authorized designee will explain to each patient the 
objectives, methods, and potential hazards of participation in the RCR.  Patients will be 
told that they are free to refuse to participate and may withdraw their specimens at any 
time and for any reason during the storage period.  A separate, specific signature will be 
required to document a patient's agreement to provide optional RCR specimens.  
Patients who decline to participate will not provide a separate signature.
The investigator should document whether or not the patient has given consent to 
participate by completing the RCR Research Sample Informed Consent eCRF.
In the event of an RCR participant's death or loss of competence, the participant's 
specimens and data will continue to be used as part of the RCR research.
4.6.12.6
Withdrawal from the Roche Clinical Repository
Patients who give consent to provide RCR specimens have the right to withdraw their 
specimens from the RCR at any time for any reason.  If a patient wishes to withdraw 
consent to the testing of his or her specimens, the investigator must inform the Medical 
Monitor in writing of the patient's wishes through use of the RCR Subject Withdrawal 
Form and, if the trial is ongoing, must enter the date of withdrawal on the RCR Research 
Sample Withdrawal of Informed Consent eCRF.  The patient will be provided with 
instructions on how to withdraw consent after the trial is closed.  A patient's withdrawal 
from Study GX28228 does not, by itself, constitute withdrawal of specimens from the 
RCR.  Likewise, a patient's withdrawal from the RCR does not constitute withdrawal from 
Study GX28228.

4.6.12.7
Monitoring and Oversight
RCR specimens will be tracked in a manner consistent with Good Clinical Practice by a 
quality-controlled, auditable, and appropriately validated laboratory information 
management system, to ensure compliance with data confidentiality as well as 
adherence to authorized use of specimens as specified in this protocol and in the 
Informed Consent Form.  Roche monitors and auditors will have direct access to 
appropriate parts of records relating to patient participation in the RCR for the purposes 
of verifying the data provided to Roche.  The site will permit monitoring, audits, IRB/EC 
review, and health authority inspections by providing direct access to source data and 
documents related to the RCR samples.
4.7
PATIENT, TREATMENT, STUDY, AND SITE DISCONTINUATION
4.7.1
Patient Discontinuation
Patients have the right to voluntarily withdraw from the study at any time for any reason.  
In addition, the investigator has the right to withdraw a patient from the study at any time.  
Reasons for withdrawal from the study may include, but are not limited to, the following:

Patient withdrawal of consent at any time

Any medical condition that the investigator or Sponsor determines may jeopardize 
the patient’s safety if he or she continues in the study

Investigator or Sponsor determines it is in the best interest of the patient

Patient non-compliance:  If a patient misses more than two consecutive monthly 
visits within any 6-month treatment period, the investigator and the Sponsor may 
consider withdrawing the patient from the study.
Every effort should be made to obtain information on patients who withdraw from the 
study.  The primary reason for withdrawal from the study should be documented on the 
appropriate eCRF.  However, patients will not be followed for any reason after consent 
has been withdrawn.  Patients who withdraw from the study will not be replaced.
See Appendix 1 and Appendix 2 for the assessments that are to be performed for 
patients who discontinue early from the study.  The reason for treatment discontinuation 
and early withdrawal from the study should be recorded on the appropriate eCRF.
Discontinued patients will not be allowed to re-enter the study.
4.7.2
Early Study Treatment Discontinuation
Patients must discontinue study treatment if they become pregnant.
The ITV treatment arm patients who are discontinued from study treatment prematurely 
will be asked to undergo the scheduled monthly visits until the LPI Month 9 visit, after 
which they will be scheduled for their final study visit 30 (7) days later.  The patients 
who are discontinuing study treatment from the Implant treatment arms will be scheduled, 
within 7 days after the treatment discontinuation decision is made, for Implant 

Ranibizumab Port Delivery System—Genentech, Inc.
74/Protocol GX28228, Version 8
explantation followed by safety visits 1 and 7 (2) days post-explantation.  Afterwards 
they will be followed in the study, attending their monthly scheduled visits, until LPI 
Month 9 visit, after which they will be scheduled for the early termination visit 
(see Appendix 1).  As per investigator discretion, explanted patients may start an 
approved anti-VEGF agent for their nAMD once the need for Implant explantation is 
confirmed and, preferably, after explantation is completed.  The sponsor will provide 
explanted patients with ranibizumab ITV treatment until the LPI Month 9 visit (if 
applicable).  All explanted Implants with remaining content will be returned to the
designee of the Sponsor for storage and potential future exploratory analysis (see 
Section 4.4).  A vitreous or aqueous humor sample will be collected at the start of 
explantation for patients undergoing an explantation procedure (see Appendix 19).
The primary reason for study treatment discontinuation should be documented on the 
appropriate eCRF.  Patients who discontinue study treatment prematurely will not be 
replaced.
4.7.3
Early Withdrawal from Study 
Every effort should be made to obtain information on patients who are withdrawing from 
the study.  The primary reason for withdrawal from the study should be documented on 
the appropriate eCRF.
Patients withdrawing from the study early should return for an early termination 
evaluation 30 (7) days following the last study drug treatment for monitoring of all 
adverse events (serious and non-serious), as well as for early termination assessments
if they are in the ITV treatment arm. The patients who are discontinuing study from the 
Implant treatment arms will be scheduled for Implant explantation within 7 days of the 
treatment discontinuation decision, followed by Safety Visits 1, 7 (2), 30 (7), and 
60 (7) days post-explantation, after which they will be scheduled for the  early 
termination visit 30 (7) days later. As per investigator judgment, these patients may 
start an approved anti-VEGF treatment for their AMD once the need for Implant 
explantation is confirmed and, preferably, after explantation is completed. All explanted
Implants, with remaining content, will be returned to the designee of the Sponsor for 
storage and potential future exploratory analysis (see Section 4.4).  A vitreous or 
aqueous humor sample will be collected at the start of explantation for patients 
undergoing an explantation procedure (see Appendix 19).
The primary reason for premature study discontinuation (which may differ from study 
treatment discontinuation) should be documented on the appropriate eCRF.  Patients 
who discontinue from the study prematurely will not be replaced and cannot re-enter the 
study.

ASSESSMENT OF SAFETY
5.1
SAFETY PLAN
The safety and tolerability of ranibizumab ITV injections have been investigated in 
previous Phase I, I/II, III, and IIIb studies in patients with AMD.  Potential safety issues 
associated with the route of administration or the pharmacology of ranibizumab in the 
study population include VA reduction, intraocular inflammation, transient and/or 
sustained elevation of IOP, cataract development or progression, retinal hemorrhage, 
vitreous hemorrhage, macular edema, endophthalmitis, retinal tear or detachment, 
hypersensitivity reactions, and arterial thromboembolic events (ATEs).  Adverse events
that should be considered ATEs include, but are not limited to, myocardial infarction and 
cerebrovascular accident (ischemic and/or hemorrhagic). Please see RPDS IB for 
further details.

Ranibizumab Port Delivery System—Genentech, Inc.
76/Protocol GX28228, Version 8
In this study, GX28228, the patients in the Implant treatment arms will return after 
Implant insertion for safety evaluation visits on Day 2 (0), Day 7 (2), and Day 14 (2); 
subsequently, the safety visit will be scheduled 7 (2) days postimplant refill with 
ranibizumab; and safety visits on 1 (0) and 7 (2) days post explantation of the Implant
for the patients who will continue to be followed up in the study; and for the patients who 
are exiting the study, safety visits on 1 (0), 7 (2), 30 (7), and 60 (7) days 
post-explantation of their Implant prior to being scheduled for the final/early termination 
visit 30 (7) days later.
All ranibizumab-treated patients will be contacted by study site personnel 3 (1) days 
after each treatment to elicit reports of any decrease in vision, eye pain, unusual redness, 
or any other new ocular symptoms in the study eye. Patients will also be asked whether 
they have taken the prescribed, self-administered, post-injection antimicrobials (if 
applicable) for their study eye as directed by the investigator.
If warranted, patients will be asked to return to the clinic as soon as possible for an 
unscheduled safety assessment visit and will be instructed to contact the investigator at 
any time should they have any health-related concerns.
Upon completion of implant insertion or explantation procedure, patients will have 
indirect ophthalmoscopy performed to monitor the Implant placement and to evaluate 
any potential Implant problems.  The treating physician will check IOP for the study eye 
only digital palpation.  These assessments must be performed prior to placing a patch on 
the eye. The patients will remain at the surgical center for approximately 40 minutes.  If 
there are no safety concerns following treatment, patients will be allowed to leave the 
surgical center after 40 (10) minutes.  If any safety concerns or immediate toxicity is 
noted, the patient will remain at the surgical center and will be treated according to the 
designated physician’s clinical judgment.  If applicable, the adverse event and treatment 
of adverse event (if applicable) will be reported on the appropriate eCRFs.
Following each treatment with ranibizumab, administered either intravitreally or as an 
Implant refill, patients will undergo a finger counting test, followed by hand motion and 
light perception tests (when necessary) performed within 15 minutes post-treatment for 
the study eye only by the designated physician; the patients in the Implant treatment 
arms will have indirect ophthalmoscopy performed after each implant refill to monitor the 
Implant and its RCE end for visible clogging and other Implant problems.  The patients
will remain at the clinic for approximately 40 minutes. If there are no safety concerns
following treatment, patients will be allowed to leave the clinic after 40 (10) minutes.  If 
any safety concerns or immediate toxicity is noted, the patient will remain at the clinic 
and will be treated according to the designated physician’s clinical judgment. If 
applicable, the adverse event and treatment of adverse event (if applicable) will be 
reported on the appropriate eCRFs. 

Ranibizumab Port Delivery System—Genentech, Inc.
77/Protocol GX28228, Version 8
Detailed ocular examinations, including indirect ophthalmoscopy and slit lamp 
examination, will be performed throughout the study.  For patients in the Implant
treatment arm, the monthly dilated binocular indirect high-magnification ophthalmoscopic
examination will include visual monitoring of the Implant placement, evaluation of visible 
clogging of the RCE tip, and evaluation of any other Implant-related problems, as well as 
data collection on the associated eCRF and/or Medical Device Complaint Form.  Routine 
hematologic, serum chemistry, coagulation, and urinalysis profiles will be obtained from 
all study patients at the screening visit.  Blood samples for assessing serum ranibizumab 
concentrations and antibodies to ranibizumab will be obtained from all study patients 
throughout the study.  In addition, optional aqueous humor samples will be obtained 
from patients in the Implant treatment arms only throughout the study.  The sample 
content retrieved during Implant refill (if applicable) and explant procedures will be 
collected and forwarded to the Sponsor designee and may be analyzed in the future.
Ranibizumab administration by ITV injection or Implant refill (if applicable) will be 
interrupted or discontinued as per the dose-interruption criteria listed in Table 6 and at 
the investigator’s discretion if he or she suspects any safety or other treatment-related 
issues.  If the investigator decides to interrupt a dose, the reason will be recorded on the 
corresponding eCRF, and if appropriate, on the Adverse Event eCRF.  In the event a 
patient experiences an adverse event in the study eye that is considered by the 
investigator to be severe in intensity or serious in nature, consideration should be given 
to interrupting the treatment or discontinuing the patient from study drug treatment or the
study.  This decision will be at the investigator’s discretion and should be recorded on 
the eCRF.
The ITV treatment arm patients who are discontinued from the study treatment 
prematurely will be encouraged to undergo the scheduled monthly visits until the LPI
Month 9 visit, after which they will be scheduled for their final study visit 30 (7) days 
later.  The patients who are discontinuing study treatment from the Implant treatment 
arms will be scheduled, within 7 days after the treatment discontinuation decision is 
made, for Implant explantation followed by safety visits 1 and 7 (2) days 
post-explantation.  Afterwards they will be followed in the study, attending their monthly 
scheduled visits, until LPI Month 9 visit, after which they will be scheduled for the early 
termination visit (see Appendix 1).  As per investigator judgement, these patients may 
start an approved anti-VEGF for their AMD once the need for Implant explantation is 
confirmed and, preferably, after explantation is completed.  All explanted Implants, with 
remaining content, will be returned to the designee of the Sponsor for storage and 
potential future exploratory analysis (see Section 4.4).  A vitreous or aqueous humor
sample will be collected at the start of explantation for patients undergoing an 
explantation procedure (see Appendix 19).
Patients discontinuing the study early should return for an early termination evaluation 
30 (7) days following the last study drug treatment for monitoring of all adverse events
(serious and non-serious), as well as for early termination assessments if they are in the 

Ranibizumab Port Delivery System—Genentech, Inc.
78/Protocol GX28228, Version 8
ITV treatment arm.  The patients who are discontinuing the study from the Implant
treatment arms will be scheduled for Implant explantation within 7 days of the 
discontinuation decision.  This will be followed by safety visits 1, 7 (2), 30 (7), and 60 
(7) days post-explantation, after which they will be scheduled for the early termination 
visit 30 (7) days later. As per investigator judgment, these patients may start an 
approved anti-VEGF treatment for their AMD once the need for Implant explantation is 
confirmed and, preferably, after explantation is completed. All explanted Implants, with
remaining content, will be returned to the designee of the Sponsor for storage and 
potential future exploratory analysis (see Section 4.4).  A vitreous or aqueous humor
sample will be collected at the start of explantation for patients undergoing an 
explantation procedure (see Appendix 19).
The incidence of all adverse events (serious and non-serious) will be recorded on 
eCRFs for the duration of this study. Serious adverse events will be collected and 
reported to the Sponsor in compliance with Good Clinical Practice guidelines.
Ongoing review of safety data will be performed by Genentech IMC consisting of the 
Medical Monitor, Clinical Scientists, Drug Safety Scientist, and Biostatistician.  External 
experts may be consulted. Following implementation of Protocol GX28228, version 5, if 
warranted, enrollment and Implant insertion surgeries may be paused to enable 
real-time review of post-implant insertion safety data by the IMC.

Rescue Treatment with Open-Label Ranibizumab For Implant 
Patients
Rescue treatment with open-label ranibizumab (0.5-mg ITV injections of 10-mg/mL 
formulation) for patients in the Implant arm is allowed only under the following 
circumstances:

Approximately 1 month and/or 2 months after occurrence of vitreous hemorrhage, if 
vitreous hemorrhage causes loss in BCVA, and neither assessment of the macula 
nor SD-OCT can be performed successfully (see Section 5.1.1.4)

At the time a patient meets criteria for lack of clinical efficacy (see Section 5.1.1.3)

In the case of progressive worsening of BCVA and/or CFT due to wet AMD activity 
across two consecutive scheduled visits, only if the patient does not meet refill 
criteria.  If a treatment is clinically necessary due to the progressive clinical 
worsening per the investigator’s judgment, rescue treatment must be discussed and 
agreed upon by the Medical Monitor prior to being introduced.  
5.1.1.3
Management of Patients Who Meet Lack of Clinical Efficacy
Criteria
Criteria for meeting lack clinical efficacy are shown in Table 7, and Table 8 describes 
how to manage patients who meet such criteria.  Patients who meet criteria for lack of 
clinical efficacy will receive rescue treatment with ITV injection of open-label ranibizumab 
as described in Section 5.1.1.2.  One month after meeting criteria for lack of clinical 
efficacy and receiving a rescue ITV ranibizumab injection, the patient will receive a 
mandatory refill with the 100-mg/mL ranibizumab formulation. At the next monthly visit 
and until the end of the study, the patient will receive a refill with the 100-mg/mL 
ranibizumab formulation if the patient meets protocol-defined refill criteria.
For information regarding patient discontinuation or early study treatment discontinuation 
refer to Section 4.7.

5.1.1.5
Implant Clogging Assessment
If an Implant is explanted, it will be analyzed for possible clogging using the following
assessments:

Serum pharmacokinetics of ranibizumab will be used to help judge whether Implant
clogging may have occurred. Aqueous humor or vitreous PK samples will be 
collected at explantation and may be used to further assess possible Implant 
clogging.  For each individual patient, possible Implant clogging will be documented 
if at least one of the following conditions are met:
At Implant insertion and prior to the first refill: serum ranibizumab 
concentrations are below the lower limit of quantification (BLQ) or below the 
baseline serum ranibizumab concentration value at all time-points prior to refills, 
that is, Day 1 (within 60 min of insertion), Day 2, Day 7, Day 14, and all monthly 
time points after Implant insertion and prior to the first refill or to the end of the 
study visit for this patient if no refill occurs.
After the first refill: serum ranibizumab concentrations are BLQ or below the 
last pre-refill serum ranibizumab concentration value at all time-points post 
refills, that is, Day 7, and all monthly time points prior to the next refill for 
2 consecutive refills or to the end of the study visit for this patient if no further 
refill occurs.

Implants identified that meet PK criteria for possible clogging will then undergo 
further diagnostics if explanted.  The Implant “complete clogging” failure statistics 
will be summarized across all Implant patients based on the first 9 months of 
Implant insertion.
5.2
SAFETY PARAMETERS AND DEFINITIONS
Safety assessments will consist of monitoring and recording adverse events, including
serious adverse events and AESIs; measurement of protocol-specified safety laboratory 
assessments; measurement of protocol-specified vital signs; and other protocol-
specified tests that are deemed critical to the safety evaluation of the study.
Certain types of events require immediate reporting to the Sponsor, as outlined in 
Section 5.4.
5.2.1
Adverse Events
According to the ICH guideline for Good Clinical Practice, an adverse event is any 
untoward medical occurrence in a clinical investigation subject administered a 
pharmaceutical product and/or medical device regardless of causal attribution.  An 
adverse event can therefore be any of the following:

Any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal product or 
device, whether or not considered related to the medicinal product or the device

Ranibizumab Port Delivery System—Genentech, Inc.
84/Protocol GX28228, Version 8

Any new disease or exacerbation of an existing disease (a worsening in the 
character, frequency, or severity of a known condition), except as described in 
Section 5.3.5.9.

Recurrence of an intermittent medical condition (e.g., headache) not present at 
baseline

Any deterioration in a laboratory value or other clinical test (e.g., fluorescein 
angiography) that is associated with symptoms or leads to a change in study 
treatment or concomitant treatment or discontinuation from study drug

Adverse events that are related to a protocol-mandated intervention, including those 
that occur prior to assignment of study treatment (e.g., screening invasive 
procedures such as biopsies)
Certain types of events require immediate reporting to the Sponsor, as outlined in 
Section 5.4.
5.2.2
Serious Adverse Events (Immediately Reportable to the 
Sponsor)
A serious adverse event is any adverse event that meets any of the following criteria:

Is fatal (i.e., the adverse event actually causes or leads to death)

Is life threatening (i.e., the adverse event, in the view of the investigator, places the 
patient at immediate risk of death)
This does not include any adverse event that had it occurred in a more severe 
form or was allowed to continue might have caused death.

Requires or prolongs inpatient hospitalization (see Section 5.3.5.10)

Results in persistent or significant disability/incapacity (i.e., the adverse event
results in substantial disruption of the patient’s ability to conduct normal life 
functions)

Is a congenital anomaly/birth defect in a neonate/infant born to a mother exposed to 
study drug

Is a significant medical event in the investigator's judgment (e.g., may jeopardize the 
patient or may require medical/surgical intervention to prevent one of the outcomes 
listed above)
The terms "severe" and "serious" are not synonymous.  Severity refers to the intensity of 
an adverse event (e.g., rated as mild, moderate, or severe; see Section 5.3.3); the event 
itself may be of relatively minor medical significance (such as severe headache without 
any further findings).
Severity and seriousness need to be independently assessed for each adverse event
recorded on the eCRF.

Ranibizumab Port Delivery System—Genentech, Inc.
85/Protocol GX28228, Version 8
Serious adverse events are required to be reported by the investigator to the Sponsor 
immediately (i.e., no more than 24 hours after learning of the event; see Section 5.4.2 for 
reporting instructions).
5.2.3
Adverse Events of Special Interest (Immediately Reportable to 
the Sponsor)
AESIs can be serious or non-serious and are required to be reported by the investigator 
to the Sponsor within 24 hours after learning of the event (see Section 5.4.2 for reporting 
instructions).  AESIs for this study include the following:
a) Adverse events resulting from medication errors
Examples of medication errors include, but are not limited to, overdose (see 
further details in the Section 5.3.5.11), incorrect dose, incorrect route, incorrect 
drug, incorrect administration, or incorrect kit.
If the medication error did result in an adverse event, the primary event term 
should reflect the adverse event that occurred as a result of the medication 
error.  The “Other” suspected causes of adverse event data field on the adverse 
event record should be reported as a medication error.
b) Sight-threatening adverse events
An adverse event is considered to be sight threatening and should be reported 
expeditiously if it meets one or more of the following criteria:

It causes a decrease of 30 letters in VA (compared with the last 
assessment of VA prior to the most recent assessment) lasting more than 
1 hour

It requires surgical intervention (i.e., conventional surgery, vitreous tap, or 
biopsy with ITV injection of anti-infective agents, or laser or retinal cryopexy 
with gas or explantation of Implant) to prevent permanent loss of sight

It is associated with severe intraocular inflammation (i.e., 4anterior 
chamber cell/flare or 4vitritis; see the definitions for intraocular 
inflammation, iritis, iridocyclitis, and vitritis in Section 5.3.5 and inflammation 
grading scales in Appendix 12).

In the opinion of the investigator, it may require medical intervention to 
prevent permanent loss of sight.
c) Suspected transmission of an infectious agent by the study drug, as defined below
Any organism, virus, or infectious particle (e.g., prion protein transmitting 
transmissible spongiform encephalopathy), pathogenic or non-pathogenic, is 
considered an infectious agent.  A transmission of an infectious agent may be 
suspected from clinical symptoms or laboratory findings that indicate an 
infection in a patient exposed to a medicinal product.  This term applies only 
when a contamination of the study drug is suspected

Ranibizumab Port Delivery System—Genentech, Inc.
86/Protocol GX28228, Version 8
d) ADEs; that is, adverse events that are considered to be related to the RPDS and to 
the use of the RPDS.  They include, but are not limited to:

Adverse events resulting from insufficient or inadequate device RPDS IFU

Adverse events related to the Implant insertion procedure 

Adverse events related to the Implant refill procedure

Adverse events related to the Implant explantation procedure

Adverse events related to the presence of the Implant within the eye

Adverse events caused by any malfunction of the RPDS including any 
adverse events resulting from an excessive release of ranibizumab into the 
eye

Adverse events resulting from use error or from intentional misuse of the 
RPDS

A lack of efficacy of ranibizumab due to inadequate release of ranibizumab 
from the Implant
In addition, any adverse event considered causally related to the RPDS must also 
always be reported as a Medical Device Complaint (Section 5.4.4).
5.3
METHODS AND TIMING FOR CAPTURING AND ASSESSING 
SAFETY PARAMETERS
The investigator is responsible for ensuring that all adverse events (whether associated 
with the drug, with the Implant or one of the ancillary devices, with any of the study 
procedures, and all adverse events not associated with any of these elements), are 
recorded on the adverse event eCRF and reported to the Sponsor in accordance with 
instructions provided in this section and in Section 5.4 to Section 5.6.  
In addition, the investigator is also responsible for reporting medical device complaints 
(see Section 5.4.4) associated with any of the components (see Table 1) of the RPDS.
For a device defect with an associated adverse event this means that the investigator 
must report both an adverse event and a Medical Device Complaint (see Section 5.4.4).
For each adverse event recorded on the adverse event eCRF, the investigator will make 
an assessment of seriousness (see Section 5.2.2 for seriousness criteria), severity (see 
Section 5.3.3), and causality (see Section 5.3.4).
5.3.1
Adverse Event Reporting Period
Investigators will seek information on adverse events at each patient contact.  All 
adverse events, whether reported by the patient or noted by study personnel, will be 
recorded in the patient’s medical record and on the adverse event eCRF.

Ranibizumab Port Delivery System—Genentech, Inc.
87/Protocol GX28228, Version 8
After informed consent has been obtained but prior to initiation of study drug
(Day 1), only serious adverse events related to a protocol-mandated intervention 
(e.g., invasive procedures such as biopsies, discontinuation of medications, or ITV 
ranibizumab given as part of pre-screening) should be reported (see Section 5.4.2 for 
instructions for reporting serious adverse events).
After initiation of study drug, all adverse events, regardless of relationship to study 
drug, Implant, or ancillary devices, or study procedures, will be reported until the 
patient’s study completion or early termination from the study. After completion or early 
termination from the study, the investigator should report any serious adverse events
that are believed to be related to prior study treatment (study drug and/or RPDS, 
see Section 5.6).
5.3.2
Eliciting Adverse Event Information
A consistent methodology of non-directive questioning should be adopted for eliciting 
adverse event information at all patient evaluation timepoints.  Examples of non-directive 
questions include the following:
"How have you felt since your last clinic visit?"
"Have you had any new or changed health problems since you were last here?"
5.3.3
Assessment of Severity of Adverse Events
Table 10 provides guidance for assessing adverse event severity.
Table 10 Adverse Event Severity Grading Scale
Severity
Description
Mild
Discomfort noticed, but no disruption of normal daily activity
Moderate
Discomfort sufficient to reduce or affect normal daily activity
Severe
Incapacitating with inability to work or to perform normal daily activity
Note:  Regardless of severity, some events may also meet seriousness criteria.  Refer to 
definition of a serious adverse event (see Section 5.2.2).
5.3.4
Assessment of Causality of Adverse Events
Investigators should use their knowledge of the patient, the circumstances surrounding 
the event, and an evaluation of any potential alternative causes.

Patients in the Implant arms:  The investigator will assess whether there is a 
potential association with each of the following “components” of the study 
intervention:  
–
Each component of the RPDS (i.e., a separate assessment for the Implant, the 
Initial Fill Needle, the Insertion Tool, the Refill Needle, and the Explant Tool)
–
The study procedures (including the procedures to insert, refill, or explant the 
Implant)
–
Ranibizumab (study drug)

Ranibizumab Port Delivery System—Genentech, Inc.
88/Protocol GX28228, Version 8
Investigators will assess any relationship between the adverse event and each 
component separately, indicating “yes” or “no” as applicable on Adverse Event eCRF.

Patients in the ITV arm:  The investigator will assess whether there is a potential 
association with each of the following “components” of the study intervention: 
–
The ITV procedure 
–
Ranibizumab (study drug)
The following guidance should be taken into consideration when assessing causality:

Temporal relationship of event onset to the initiation of study drug, implant and its 
insertion, refill, or explantation procedures or due to other RPDS components (see 
Table 1) or due to ITV injection procedure.  

Course of the event, considering especially the effects of dose reduction, 
discontinuation of study drug, or reintroduction of study drug (as applicable)

Known association of the event with study drug, Implant or other RPDS 
components/procedures, or with similar treatments

Known association of the event with the disease under study

Presence of risk factors in the patient or use of concomitant medications known to 
increase the occurrence of the event

Presence of nontreatment-related factors that are known to be associated with the 
occurrence of the event
5.3.5
Procedures for Recording Adverse Events
Investigators should use correct medical terminology/concepts when recording adverse 
events on the adverse event eCRF.  Avoid colloquialisms and abbreviations.
Only one adverse event term should be recorded in the event field on the adverse event
eCRF.
For the purposes of reporting events of infection and inflammation, the following terms 
and definitions should be used:

Iritis:  the presence of inflammatory cells in the anterior chamber
The presence of aqueous humor flare alone will not constitute iritis but should 
be documented as an anterior chamber flare for adverse event reporting 
purposes.

Iridocyclitis:  the presence of inflammatory cells in both the aqueous humor 
and vitreous

Vitritis:  the presence of active inflammation in the vitreous, demonstrated by the 
presence of inflammatory cells (trace or greater)
Active inflammation in the vitreous should be clinically differentiated 
from cellular debris from prior episodes of inflammation, hemorrhage, or other 
causes.

Ranibizumab Port Delivery System—Genentech, Inc.
89/Protocol GX28228, Version 8

Endophthalmitis:  diffuse intraocular inflammation predominantly involving the 
vitreous cavity but possibly also involving the anterior chamber, implying a 
suspected underlying infectious cause. A culture is required prior to initiating 
antibiotic treatment for presumed endophthalmitis.
Note:  Trace benign, aqueous humor pigmented cells visible on slitlamp examination that 
are caused by dilation and are not RBCs or WBCs or the result of any ocular disorder 
should not be recorded as an adverse event.
5.3.5.1
Diagnosis versus Signs and Symptoms
A diagnosis (if known) should be recorded on the adverse event eCRF rather than 
individual signs and symptoms (e.g., record only liver failure or hepatitis rather than 
jaundice, asterixis, and elevated transaminases).  However, if a constellation of signs 
and/or symptoms cannot be medically characterized as a single diagnosis or syndrome 
at the time of reporting, each individual event should be recorded on the adverse event
eCRF.  If a diagnosis is subsequently established, all previously reported adverse events 
based on signs and symptoms should be nullified and replaced by one adverse event
report based on the single diagnosis, with a starting date that corresponds to the starting 
date of the first symptom of the eventual diagnosis.
5.3.5.2
Adverse Events That Are Secondary to Other Events
In general, adverse events that are secondary to other events (e.g., cascade events or 
clinical sequelae) should be identified by their primary cause, with the exception of 
severe or serious secondary events.  A medically significant secondary adverse event
that is separated in time from the initiating event should be recorded as an independent 
event on the adverse event eCRF.  For example:

If vomiting results in mild dehydration with no additional treatment in a healthy adult, 
only vomiting should be reported on the eCRF.

If vomiting results in severe dehydration, both events should be reported separately 
on the eCRF.

If a severe gastrointestinal hemorrhage leads to renal failure, both events should be 
reported separately on the eCRF.

If dizziness leads to a fall and consequent fracture, all three events should be 
reported separately on the eCRF.

If neutropenia is accompanied by an infection, both events should be reported 
separately on the eCRF.
All adverse events should be recorded separately on the adverse event eCRF if it is 
unclear as to whether the events are associated.
5.3.5.3
Persistent or Recurrent Adverse Events
A persistent adverse event is one that extends continuously, without resolution, between 
patient evaluation timepoints.  Such events should only be recorded once on the 
adverse event eCRF.  The initial severity (intensity) of the event will be recorded at the 

Ranibizumab Port Delivery System—Genentech, Inc.
90/Protocol GX28228, Version 8
time the event is first reported.  If a persistent adverse event becomes more severe, the 
most extreme severity should also be recorded on the adverse event eCRF.  If the event 
becomes serious, it should be reported to the Sponsor immediately (i.e., no more than 
24 hours after learning that the event became serious; see Section 5.4.2 for reporting 
instructions).  The adverse event eCRF should be updated by changing the event from 
"non-serious" to "serious," providing the date that the event became serious, and 
completing all data fields related to serious adverse events.
A recurrent adverse event is one that resolves between patient evaluation timepoints 
and subsequently recurs.  Each recurrence of an adverse event should be recorded as a 
separate event on the adverse event eCRF.
5.3.5.4
Abnormal Laboratory Values
Not every laboratory abnormality qualifies as an adverse event.  A laboratory test result 
must be reported as an adverse event if it meets any of the following criteria:

Is accompanied by clinical symptoms

Results in a change in study treatment (e.g., dosage modification, treatment 
interruption, or treatment discontinuation)

Results in a medical intervention (e.g., potassium supplementation for hypokalemia) 
or a change in concomitant therapy

Is clinically significant in the investigator’s judgment
It is the investigator’s responsibility to review all laboratory findings.  Medical and 
scientific judgment should be exercised in deciding whether an isolated laboratory 
abnormality should be classified as an adverse event.
If a clinically significant laboratory abnormality is a sign of a disease or syndrome 
(e.g., alkaline phosphatase and bilirubin 5the upper limit of normal [ULN] associated 
with cholestasis), only the diagnosis (i.e., cholestasis) should be recorded on the 
adverse event eCRF.
If a clinically significant laboratory abnormality is not a sign of a disease or syndrome, 
the abnormality itself should be recorded on the adverse event eCRF, along with a 
descriptor indicating if the test result is above or below the normal range (e.g., "elevated 
potassium," as opposed to "abnormal potassium").  If the laboratory abnormality can be 
characterized by a precise clinical term per standard definitions, the clinical term should 
be recorded as the Ae.  For example, an elevated serum potassium level of 7.0 mEq/L 
should be recorded as "hyperkalemia."
Observations of the same clinically significant laboratory abnormality from visit to visit 
should only be recorded once on the adverse event eCRF (see Section 5.3.5.3 for 
details on recording persistent adverse event).

Ranibizumab Port Delivery System—Genentech, Inc.
91/Protocol GX28228, Version 8
5.3.5.5
Abnormal Vital Sign Values
Not every vital sign abnormality qualifies as an adverse event.  A vital sign result must
be reported as an adverse event if it meets any of the following criteria:

Is accompanied by clinical symptoms

Results in a change in study treatment (e.g., dosage modification, treatment 
interruption, or treatment discontinuation)

Results in a medical intervention or a change in concomitant therapy

Is clinically significant in the investigator’s judgment
It is the investigator’s responsibility to review all vital sign findings.  Medical and scientific 
judgment should be exercised in deciding whether an isolated vital sign abnormality 
should be classified as an adverse event.
If a clinically significant vital sign abnormality is a sign of a disease or syndrome 
(e.g., high blood pressure), only the diagnosis (i.e., hypertension) should be recorded on 
the adverse event eCRF.
Observations of the same clinically significant vital sign abnormality from visit to visit 
should only be recorded once on the adverse event eCRF (see Section 5.3.5.3 for 
details on recording persistent adverse events).
5.3.5.6
Abnormal Liver Function Tests
The finding of an elevated ALT or AST (3the ULN) in combination with either an 
elevated total bilirubin (2the ULN) or clinical jaundice in the absence of cholestasis or 
other causes of hyperbilirubinemia is considered to be an indicator of severe liver injury
(as defined by Hy’s law).  Therefore, investigators must report as a serious adverse 
event the occurrence of either of the following:

Treatment-emergent ALT or AST 3the ULN in combination with total bilirubin 
2the ULN

Treatment-emergent ALT or AST 3the ULN in combination with clinical jaundice
The most appropriate diagnosis or, if a diagnosis cannot be established, the abnormal 
laboratory values should be recorded on the adverse event eCRF (see Section 5.3.5.1) 
and reported to the Sponsor immediately (i.e., no more than 24 hours after learning of 
the event).
5.3.5.7
Deaths
All deaths that occur during the protocol-specified adverse event reporting period (see 
Section 5.3.1), regardless of relationship to study drug, must be recorded on the adverse 
event eCRF and immediately reported to the Sponsor (see Section 5.4.2).
Death should be considered an outcome and not a distinct event.  The event or condition 
that caused or contributed to the fatal outcome should be recorded as the single medical 

Ranibizumab Port Delivery System—Genentech, Inc.
92/Protocol GX28228, Version 8
concept on the adverse event eCRF.  Generally, only one such event should be reported.  
If the cause of death is unknown and cannot be ascertained at the time of reporting, 
"unexplained death" should be recorded on the adverse event eCRF.  If the cause of 
death later becomes available (e.g., after autopsy), "unexplained death" should be 
replaced by the established cause of death.  The term "sudden death" should not be 
used unless combined with the presumed cause of death (e.g., "sudden cardiac death").
5.3.5.8
Preexisting Medical Conditions
A preexisting medical condition is one that is present at the screening visit for this study.  
Such conditions should be recorded on the Medical History and Baseline Conditions 
eCRFs.
A preexisting medical condition should be recorded as an adverse event only if the 
frequency, severity, or character of the condition worsens during the study.  When 
recording such events on the adverse event eCRF, it is important to convey the concept 
that the preexisting condition has changed by including applicable descriptors 
(e.g., "more frequent headaches").
5.3.5.9
Worsening of Neovascular Age-Related Macular Degeneration
in Study Eye
Study eye medical occurrences or symptoms of deterioration that are anticipated as part 
of the nAMD disease state should only be recorded as an adverse event if judged by the 
investigator to have unexpectedly worsened in severity or frequency or changed in 
nature at any time during the study.  When recording an unanticipated worsening of
study eye nAMD on the adverse event eCRF, it is important to convey the concept that 
the condition has changed by including applicable descriptors (e.g., "accelerated 
nAMD").
5.3.5.10
Hospitalization or Prolonged Hospitalization
Any adverse event that results in hospitalization (i.e., in-patient admission to a hospital)
or prolonged hospitalization should be documented and reported as a serious adverse 
event (per the definition of serious adverse event in Section 5.2.2), except as outlined 
below.  
There are some hospitalization scenarios that do not require reporting as a serious 
adverse event when there is no occurrence of an adverse event.  These scenarios 
include a planned hospitalization or prolonged hospitalization to undergo a diagnostic or 
elective surgical procedure for a preexisting medical condition other than ocular that has 
not changed.
5.3.5.11
Adverse Events Associated with an Overdose or Error in 
Drug Administration
An overdose is the accidental or intentional use of a drug in an amount higher than the 
dose being studied.  An overdose or incorrect administration of study treatment is not 
itself an adverse event, but it may result in an adverse event.  All adverse events

Ranibizumab Port Delivery System—Genentech, Inc.
93/Protocol GX28228, Version 8
associated with an overdose or incorrect administration of study drug should be 
recorded on the adverse event eCRF and should be reported to the Sponsor 
immediately (i.e., no more than 24 hours after learning of the event; see Section 5.4.2).
Defects in the device that are not associated with adverse events are captured 
according to Section 5.4.4.
5.3.5.12
Patient-Reported Outcome Data
Adverse event reports will not be derived from patient-reported outcome (PRO) data by 
the Sponsor, and safety analyses will not be performed using PRO data.  However, if 
any PRO responses suggestive of a possible adverse event are identified during site 
review of the PRO data, the investigator will determine whether the criteria for an 
adverse event have been met and, if so, will report the event on the adverse event eCRF.
5.4
IMMEDIATE REPORTING REQUIREMENTS FROM 
INVESTIGATOR TO SPONSOR
Certain events require immediate reporting to allow the Sponsor to take appropriate 
measures to address potential new risks in a clinical trial.  The investigator must report 
such events to the Sponsor immediately; under no circumstances should reporting take 
place more than 24 hours after the investigator learns of the event.  The following is a list 
of events that the investigator must report to the Sponsor within 24 hours after learning 
of the event, regardless of relationship to study drug:

Serious adverse events (see Section 5.4.2 for further details)

AESI (see Section 5.4.2 for further details)

Pregnancies (see Section 5.4.3 for further details)
The investigator must report new significant follow-up information for these events to the 
Sponsor immediately (i.e., no more than 24 hours after becoming aware of the 
information).  New significant information includes the following:

New signs or symptoms or a change in the diagnosis

Significant new diagnostic test results

Change in causality based on new information

Change in the event’s outcome, including recovery

Additional narrative information on the clinical course of the event
Investigators must also comply with local requirements for reporting serious adverse 
events to the local health authority (HA) and Institutional Review Board (IRB)/Ethics 
Committee (EC).

well as Medical Monitor contact information, will be distributed to all investigators. 
5.4.2
Reporting Requirements for Serious Adverse Events and 
Non-Serious and Serious Adverse Events of Special Interest
5.4.2.1
Events That Occur Prior to Initiation of Study Drug (Day 1)
After informed consent has been obtained but prior to initiation of study drug, only 
serious adverse events related to a protocol-mandated intervention (e.g., invasive 
procedures such as biopsies, discontinuation of medications, or ITV ranibizumab given 
as part of pre-screening) should be reported.  The Serious Adverse Event/Adverse 
Event of Special Interest Reporting Form provided to investigators should be completed 
and submitted to the Sponsor or its designee immediately (i.e., no more than 24 hours 
after learning of the event), either by faxing or by scanning and emailing the form using 
the fax number or email address provided to investigators.
5.4.2.2
Events That Occur After Study Drug Initiation
After initiation of study drug, serious adverse events, and any AESI will be reported until 
30 (7) days after the last study drug administration for the ITV injection treatment arm 
and until 90 (7) days after the Implant explantation for the Implant treatment arms. 
However, if any patient continues to be followed in the study after an early 
discontinuation of the treatment, the adverse events will be reported until their study 
completion.  Investigators should record all case details that can be gathered 
immediately (i.e., within 24 hours after learning of the event) on the adverse event eCRF 
and submit the report via the electronic data capture (EDC) system.  A report will be 
generated and sent to Roche Safety Risk Management by the EDC system.

Ranibizumab Port Delivery System—Genentech, Inc.
95/Protocol GX28228, Version 8
In the event that the EDC system is unavailable, the Serious Adverse Event/Adverse 
Event of Special Interest Reporting Form provided to investigators should be completed 
and submitted to the Sponsor or its designee immediately (i.e., no more than 24 hours 
after learning of the event), either by faxing or by scanning and emailing the form using 
the fax number or email address provided to investigators.  Once the EDC system is 
available, all information will need to be entered and submitted via the EDC system.  
Instructions for reporting post-study adverse events are provided in Section 5.6.
5.4.3
Reporting Requirements for Pregnancies
5.4.3.1
Pregnancies in Female Patients
Female patients of childbearing potential will be instructed to immediately inform the 
investigator if they become pregnant during the study or within 30 days after the last 
dose of study drug.  A Pregnancy Report eCRF should be completed by the investigator 
immediately (i.e., no more than 24 hours after learning of the pregnancy) and submitted 
via the EDC system.  A pregnancy report will automatically be generated and sent to 
Roche Safety Risk Management.  Pregnancy should not be recorded on the adverse 
event eCRF.  The investigator should discontinue study drug and counsel the patient,
discussing the risks of the pregnancy and the possible effects on the fetus.  Monitoring 
of the patient should continue until conclusion of the pregnancy.  Any serious adverse 
events associated with the pregnancy (e.g., an event in the fetus, an event in the mother 
during or after the pregnancy, or a congenital anomaly/birth defect in the child) should be 
reported on the adverse event eCRF.
In the event that the EDC system is unavailable, the Clinical Trial Pregnancy Reporting 
Form provided to investigators should be completed and submitted to the Sponsor or its 
designee immediately (i.e., no more than 24 hours after learning of the pregnancy), 
either by faxing or by scanning and emailing the form using the fax number or email 
address provided to investigators.  Once the EDC system is available, all information will 
need to be entered and submitted via the EDC system.
5.4.3.2
Pregnancies in Female Partners of Male Patients
Male patients will be instructed through the ICF to immediately inform the investigator if 
their partner becomes pregnant during the study or within 30 days after the last dose of 
study drug.  A Pregnancy Report eCRF should be completed by the investigator 
immediately (i.e., no more than 24 hours after learning of the pregnancy) and submitted 
via the EDC system.  Attempts should be made to collect and report details of the course 
and outcome of any pregnancy in the partner of a male patient exposed to study drug.  
The pregnant partner will need to sign an Authorization for Use and Disclosure of 
Pregnancy Health Information to allow for follow-up on her pregnancy.  Once the 
authorization has been signed, the investigator will update the Pregnancy Report eCRF 
with additional information on the course and outcome of the pregnancy.  An investigator 
who is contacted by the male patient or his pregnant partner may provide information on 

Ranibizumab Port Delivery System—Genentech, Inc.
96/Protocol GX28228, Version 8
the risks of the pregnancy and the possible effects on the fetus, to support an informed 
decision in cooperation with the treating physician and/or obstetrician.
In the event that the EDC system is unavailable, follow reporting instructions provided in 
Section 5.4.3.1.
5.4.3.3
Abortions
Any abortion should be classified as a serious adverse events (as the Sponsor considers 
abortions to be medically significant), recorded on the adverse event eCRF, and 
reported to the Sponsor immediately (i.e., no more than 24 hours after learning of the 
event; see Section 5.4.2).  
5.4.3.4
Congenital Anomalies/Birth Defects
Any congenital anomaly/birth defect in a child born to a female patient exposed to study 
drug or the female partner of a male patient exposed to study drug should be classified 
as a serious adverse event, recorded on the adverse event eCRF, and reported to the 
Sponsor immediately (i.e., no more than 24 hours after learning of the event; see 
Section 5.4.2).
5.4.4
Reporting Requirements for Medical Device Complaints
In this study, the Implant and the ancillary devices are considered medical devices.  The 
investigator must report all RPDS medical device complaints related to the Implant and 
ancillary devices (see Table 1) to the Sponsor.  
The investigator should provide as much information as possible to the personnel 
completing the IMP Deviation Form, including the product batch number.  The form will 
be forwarded to the Sponsor or its designee immediately (i.e., no more than 24 hours 
after learning of the event) (refer to the Study manual for further details).  
If the device complaint is also associated with an adverse event in a study participant, 
then the adverse event must additionally be reported on the adverse event eCRF
submitted through the EDC system.  If the event is serious or an AESI, the adverse 
event eCRF must be completed immediately (i.e., no more than 24 hours after learning 
of the event), as outlined in Section 5.4.2. 
If the medical device causes an adverse event to an individual other than the study 
patient (e.g., study site personnel), the event should be reported on the Medical Device 
Complaint form and the adverse event to Roche Safety Risk Management via telephone 
(see Study Manual for more details).
5.4.4.1
Device Defects or Deficiencies that Could Have Led to Medical 
Occurrence
Device deficiencies (inadequacy with respect to identity, quality, durability, reliability, 
safety or performance and including malfunctions, and inadequate labeling) that did not 
lead to an adverse event but could have led to a medical occurrence if suitable action 

Ranibizumab Port Delivery System—Genentech, Inc.
97/Protocol GX28228, Version 8
had not been taken, if intervention had not been made, or if circumstances had been 
less fortunate must be reported via the medical device complaints process immediately 
(i.e., no more than 24 hours after learning of the event) (refer to the Study manual for 
further details). 
5.5
FOLLOW-UP OF PATIENTS AFTER ADVERSE EVENTS
5.5.1
Investigator Follow-Up
The investigator should follow each adverse event until the event has resolved to 
baseline grade or better, the event is assessed as stable by the investigator, the patient 
is lost to follow-up, or the patient withdraws consent.  Every effort should be made to 
follow all serious adverse events considered to be related to study drug or trial-related 
procedures until a final outcome can be reported.
During the study period, resolution of adverse events (with dates) should be documented 
on the Adverse Event eCRF and in the patient’s medical record to facilitate source data 
verification.
All pregnancies reported during the study should be followed until pregnancy outcome.  
If the EDC system is not available at the time of pregnancy outcome, follow reporting 
instructions provided in Section 5.4.3.
5.5.2
Sponsor Follow-Up
For serious adverse events, non-serious AESI, and pregnancies, the Sponsor or a 
designee may follow-up by telephone, fax, electronic mail, and/or a monitoring visit to 
obtain additional case details and outcome information (e.g., from hospital discharge 
summaries, consultant reports, autopsy reports) in order to perform an independent 
medical assessment of the reported case.
5.6
POST-STUDY ADVERSE EVENTS
The Sponsor should be notified if the investigator becomes aware of any serious 
adverse event that occurs after the end of the adverse event reporting period (defined as 
30 (7) days after the last dose of study drug for ITV treatment arm and 90 (7) days 
after the Implant explantation for patients in the Implant treatment arms), if the event is 
believed to be related to prior study drug treatment or due to the Implant.
These events should be reported through use of the Adverse Event eCRF.  However, if 
the EDC system is not available, the investigator should report these events directly to 
the Sponsor or its designee, either by faxing or by scanning and emailing the Serious 
Adverse Event/Adverse Event of Special Interest Reporting Form using the fax number
or email address provided to investigators.

EXPEDITED REPORTING TO HEALTH AUTHORITIES, 
INVESTIGATORS, INSTITUTIONAL REVIEW BOARDS, AND 
ETHICS COMMITTEES
The Sponsor will promptly evaluate all serious adverse events and non-serious AESI 
against cumulative product experience to identify and expeditiously communicate 
possible new safety findings to investigators, IRBs, ECs, and applicable health 
authorities based on applicable legislation.
To determine reporting requirements for single adverse event cases, the Sponsor will 
assess the expectedness of these events using the following reference document:

RPDS IB
The Sponsor will compare the severity of each event and the cumulative event 
frequency reported for the study with the severity and frequency reported in the 
applicable reference document.
Reporting requirements will also be based on the investigator's assessment of causality 
and seriousness, with allowance for upgrading by the Sponsor as needed.
6.
STATISTICAL CONSIDERATIONS AND ANALYSIS PLAN
The primary analyses will take place after LPI has completed the Month 9 visit. Detailed 
specifications of the statistical methods will be described in the SAP.
6.1
DETERMINATION OF SAMPLE SIZE
This study is exploratory in nature and designed to estimate the time to first refill (TTFR) 
for each of the RPDS treatment arms (10 mg/mL, 40 mg/mL, and 100 mg/mL) enrolling 
60 patients in each of the RPDS treatment arms.  The sample size of approximately 
220 randomized patients will be adequate to evaluate the primary objective of the study. 
PK/PD modeling and simulation was performed to inform key assumptions used in 
sample size calculation. Given the simulation results, the HR for comparing the 
100-mg/mL arm with the 10-mg/mL arm was estimated to be 0.66 for TTFR. Assuming 
this HR, a total of at least 125 events from all three Implant groups is expected at the 
primary analysis time (approximately 85 events in the 10-mg/mL group and a higher 
dose group).  With 85 events, this study will have approximately 80% power to detect an
HR0.66 between the two Implant arms using a log-rank test at a one-sided significance 
level of 15%. No multiplicity adjustment is planned for this Phase II study.
Forty patients in the ITV arm are considered sufficient to compare each device arm 
versus the ITV arm in change in BCVA from baseline through Month 9 (assuming an 
estimated SD10 letters, a two-sided 80% CI will extend approximately 2.62 letters from 
the observed mean).

99/Protocol GX28228, Version 8
6.2
SUMMARIES OF CONDUCT OF STUDY
The demographic and baseline characteristics, such as age, sex, race/ethnicity, baseline 
VA, angiographic and clinical evaluation of CNV, time since diagnosis of nAMD, 
and stratification factors including baseline BCVA score and number of prior
anti-VEGF injections will be summarized by treatment group using descriptive statistics.
6.3
SUMMARIES OF TREATMENT GROUP COMPARABILITY
The demographic and baseline characteristics, such as age, sex, race/ethnicity, baseline 
VA, angiographic and clinical evaluation of CNV, time since diagnosis of nAMD, baseline 
safety (patients outside the expected normal range for vital signs and laboratory test 
results), and baseline disease characteristics (i.e., BCVA and OCT parameters) will be 
summarized by treatment arm. 
6.4
EFFICACY ANALYSES
6.4.1
Primary Efficacy Analysis
The primary endpoint for this analysis will be time to first meeting refill criteria.  The 
primary analyses will be based on data as of 9 months after last patient’s entry into the 
study. For patients without any refills prior to or on the cut-off date of 9 months after LPI, 
the time of refill will be censored. The censoring date will be defined as the date of a 
patient’s last visit before the cut-off date of 9 months after LPI, or the date when the 
patient discontinues from the study, whichever occurs first.
The primary analysis population for efficacy is the modified intent-to-treat population 
defined as all randomized patients who were randomly assigned to study treatment 
receive study treatment.  Patients will be summarized by treatment arm and analyzed 
according to the treatment actually received and not according to the treatment they 
were randomized to receive, in the event of a discrepancy.  
To support the dose level selection among the Implant groups, the primary analysis for 
TTFR will include the following pair-wise group comparisons, each with a stratified log-
rank test at a one-sided significance level of 15%. The stratification factors to be 
included are baseline BCVA score (65 letters vs. 66 letters) and number of anti-VEGF 
ITV injections (3 vs.4).

Implant with 100 mg/mL versus Implant with 10 mg/mL

Implant with 100 mg/mL versus Implant with 40 mg/mL

Implant with 40 mg/mL versus Implant with 10 mg/mL
In addition, the HR for each pair-wise comparison of the treatment arms will be 
estimated using a Cox proportional hazards regression model stratified by baseline 
BCVA score (65 letters vs. 66 letters) and number of prior anti-VEGF ITV injections 
(3 vs. 4) with main effects for treatment.  Estimated HRs for each pair-wise 
comparison will be presented with the corresponding 80% CIs.  

Ranibizumab Port Delivery System—Genentech, Inc.
100/Protocol GX28228, Version 8
KaplanMeier plots will be provided showing TTFR by implant group. Median time to 
first meeting refill criteria will be calculated for each treatment arm with the Kaplan Meier 
method, and the corresponding 80% confidence intervals will also be reported.

Moreover, for each treatment group, percentage of patients not meeting the 
protocol-defined first refill criteria by Months 4, 5, 6, 7, 8, and 9, derived from 
Kaplan-Meier estimates will be provided.
6.4.2
Secondary Efficacy Analysis
A secondary efficacy outcome measure is the change in BCVA from baseline through 
Month 9 (by month). Missing BCVA data, prior to or at Month 9 for each patient, will be 
imputed using the last observation carry forward (LOCF).  Comparison of implant arms 
(10 mg/mL, 40 mg/mL, and 100 mg/mL) versus the monthly ITV arm will be assessed 
using an analysis of covariance (ANCOVA) model with an effect for treatment and with 
covariate adjustments for baseline stratification factors:  baseline BCVA score 
(65 letters vs. 66 letters) and number of anti-VEGF ITV injections (3 vs. 4).  
Separate models will be fit for each pairwise comparison and each study month.  The 
dependent variables will be change from baseline in BCVA at each of Months 19.  
Model-based (least squares) estimates of the pairwise treatment differences will be 
provided and 80% CIs.  Figures showing mean and median change in BCVA over time, 
by treatment group, will be provided.
The ANCOVA model above will be repeated using change from baseline in CFT from 
baseline through Month 9 (by month) as the outcome.  The stratification factors and 
baseline CFT will be included in the model as covariates.  Mean change from baseline in 
CFT from baseline through Month 9 (by month) will be compared between the implant 
arms and the monthly ITV arm.
In order to evaluate whether the Implant clogging rate exceeds 10% within the first 
9 months, the proportion of clogged Implants will be estimated and the 80% CI will be 
calculated based on the binomial distribution.  All clogging data from patients in the 
implant arms will be pooled for this analysis.
Additional statistical summaries will be reported for the secondary efficacy outcome 
measures as listed in Section 3.5.2. Detailed specifications of the statistical methods will 
be described in the SAP.

6.5
SAFETY ANALYSES
All patients receiving at least one study treatment will be included in the safety analysis.  
Counts and incidence rates by treatment group for the following safety endpoints will be
provided:

Ocular and non-ocular adverse events and serious adverse events

"Prespecified RPDS-associated adverse events" (see Section 6.5.1)

Positive serum antibodies to ranibizumab
For "prespecified RPDS-associated adverse events”, the incidence in all implant arms 
patients will also be summarized.  
6.5.1
Adverse Events
Verbatim descriptions of treatment-emergent adverse events will be mapped to 
thesaurus terms.  Treatment-emergent adverse events will be defined as events 
beginning during or after surgical insertion/explantation of the Implant or the first 
ranibizumab ITV injection through the completion of the study or until a patient 
discontinues prematurely.  Adverse events will be tabulated by body system, high-level 
term, and preferred term.  Separate summaries will be prepared for non-ocular and 
ocular adverse events, with events in the study eye and fellow eye summarized 
separately.  Serious adverse events will be summarized similarly.  Adverse events
leading to discontinuation from the study or treatment will be listed and tabulated.
ADEs are adverse events that are considered to be related to the RPDS and to the use 
of the RPDS. Of particular interest are the following “Prespecified RPDSassociated 
adverse events”:  

Vitreous hemorrhage associated with a 30-letter decrease of BCVA on ETDRS 
chart compared with the last assessment of BCVA prior to the onset of vitreous 
hemorrhage lasting 1 month

Reduced VA (30 letters loss from previous scheduled visit)

Traumatic cataract

Endophthalmitis

Damage to sclera

Retinal detachment

Interference of the Implant with visual field
In addition to the “Prespecified RPDSassociated adverse events”, any other ocular 
adverse events and serious adverse events attributed by the investigator to the:  
1) Implant insertion procedure, 2) Implant refill procedure, 3) Implant explantation 
procedure, and 4) study drug, will be reported.

vital signs over the course of the study will be provided.
6.5.5
Ocular Assessments
Results of the following ocular assessments will be summarized by timepoint and by eye 
(study vs. non-study) as applicable, using descriptive summaries:  IOP, fluorescein 
angiography, and fundus photography.  Changes from baseline for selected ocular 
assessments will be tabulated.  The presence of intraocular inflammation and vitreous 
hemorrhage, as determined from the slitlamp examination, will be tabulated by grade 
(according to grading scales for flare/cells and vitreal hemorrhage density in
Appendix 12).  The presence of retinal break or detachment as determined from 
ophthalmoscopy will be tabulated.
6.6
PHARMACOKINETIC ANALYSES
Individual and mean serum ranibizumab concentration over time will be tabulated and 
plotted by dose level and by refill number.  The serum pharmacokinetics of ranibizumab 
will be characterized by estimating AUC, Cmax, tmax, t1/2, and Ctrough between dose intervals.  
Estimates for these parameters will be tabulated and summarized by descriptive 
statistics.  Additional PK analyses may be conducted as appropriate.  More details are 
described in Section 3.5.4.
6.7
PATIENT-REPORTED OUTCOME ANALYSES
For each scheduled assessment, descriptive statistics will be computed for the total 
MacTSQ score and for the two subscales: 1) information provision and convenience 
and 2) impact of treatment.  The scoring algorithm and rules for handling missing data 
will be provided in the SAP.

6.8
EXPLORATORY ANALYSES
Detailed specifications of the statistical methods for the exploratory analyses will be 
described in the SAP.
6.8.1
Time to Event Analysis with Data after Month 9
In case the required number of events (first refills) is not reached by Month 9, the 
primary analysis will be repeated as a follow-up analysis using all of the data collected 
up to the time when the required number of events is met. 
In addition, the primary efficacy analysis described in Section 6.4.1 will be repeated 
based on the full data collected during the entire study as an exploratory analysis. This 
analysis is considered supportive to the primary efficacy analysis.
6.8.2
Analysis of Time to Subsequent Refills
Time from last refill to subsequent refills will be analyzed for patients in the Implant arms 
as appropriate.  Details of the analysis will be described in the statistical analysis plan.
6.9
FLEXIBLE INTERIM ANALYSIS
Given the exploratory nature of this study, the Sponsor may choose to conduct up to two 
interim analyses.  The decision to conduct an optional interim analysis and the timing of 
the analysis will be documented in the Sponsor’s trial master file prior to the conduct of 
the interim analysis.  The interim analysis will be performed by members of the 
Sponsor’s unmasked study team and will be interpreted by the unmasked IMC and 
appropriate senior management personnel.  Access to treatment assignment information 
will follow the Sponsor’s standard procedures.  The details of the timing and scope of the 
interim analysis, if any, will be specified in the IMC Agreement.

DATA COLLECTION AND MANAGEMENT
7.1
DATA QUALITY ASSURANCE
The Sponsor will be responsible for the data management of this study, including quality 
checking of the data.  Data entered manually will be collected via EDC using eCRFs.  
Sites will be responsible for data entry into the EDC system.  In the event of discrepant 
data, the Sponsor will request data clarification from the sites, which the sites will resolve 
electronically in the EDC system.  
The Sponsor will produce an EDC Study Specification document that describes the 
quality checking to be performed on the data.  Central laboratory and reading center 
data will be sent directly to the Sponsor, using the Sponsor’s standard procedures to 
handle and process the electronic transfer of these data.
eCRFs and correction documentation will be maintained in the EDC system’s audit trail.  
System backups for data stored by the Sponsor and records retention for the study data 
will be consistent with the Sponsor’s standard procedures. Data from PRO 

Ranibizumab Port Delivery System—Genentech, Inc.
104/Protocol GX28228, Version 8
questionnaires will be forwarded to the Sponsor electronically.  The Sponsor will supply 
eCRF specifications for this study.  For additional details of the data quality assurance
please see the Data Quality Review Plan.
7.2
ELECTRONIC CASE REPORT FORMS 
eCRFs are to be completed using a Sponsor-designated EDC system.  Sites will receive 
training and have access to Help Text within EDC for appropriate eCRF completion.  
eCRFs will be submitted electronically to the Sponsor and should be handled in 
accordance with instructions from the Sponsor.
All eCRFs should be completed by designated, trained site staff.  eCRFs should be 
reviewed and electronically signed and dated by the investigator or a designee.
At the end of the study, the investigator will receive patient data for his or her site in a 
readable format on a compact disc that must be kept with the study records.  
Acknowledgement of receipt of the compact disc is required.
7.3
PATIENT-REPORTED OUTCOME DATA
Data from paper PRO questionnaires will be entered into the EDC system by site staff.
7.4
SOURCE DATA DOCUMENTATION
Study monitors will perform ongoing source data verification to confirm that critical 
protocol data (i.e., source data) entered into the eCRFs by authorized site personnel are 
accurate, complete, and verifiable from source documents. 
Source documents (paper or electronic) are those in which patient data are recorded 
and documented for the first time.  They include, but are not limited to, hospital records, 
clinical and office charts, laboratory notes, memoranda, PROs, evaluation checklists, 
pharmacy dispensing records, recorded data from automated instruments, copies of 
transcriptions that are certified after verification as being accurate and complete, 
microfiche, photographic negatives, microfilm or magnetic media, X-rays, patient files, 
and records kept at pharmacies, laboratories, and medico-technical departments 
involved in a clinical trial.
Before study initiation, the types of source documents that are to be generated will be 
clearly defined in the Trial Monitoring Plan (TMP).  This includes any protocol data to be 
entered directly into the eCRFs (i.e., no prior written or electronic record of the data) and 
considered source data.
Source documents that are required to verify the validity and completeness of data 
entered into the eCRFs must not be obliterated or destroyed and must be retained per 
the policy for retention of records described in Section 7.6.

Ranibizumab Port Delivery System—Genentech, Inc.
105/Protocol GX28228, Version 8
To facilitate source data verification, the investigators and institutions must provide the 
Sponsor direct access to applicable source documents and reports for trial-related 
monitoring, Sponsor audits, and IRB/EC review.  The study site must also allow 
inspection by applicable health authorities. Please see TMP for additional details.
7.5
USE OF COMPUTERIZED SYSTEMS
When clinical observations are entered directly into a study site’s computerized medical 
record system (i.e., in lieu of original hardcopy records), the electronic record can serve 
as the source document if the system has been validated in accordance with HA
requirements pertaining to computerized systems used in clinical research.  An 
acceptable computerized data collection system allows preservation of the original entry 
of data.  If original data are modified, the system should maintain a viewable audit trail 
that shows the original data as well as the reason for the change, name of the person 
making the change, and date of the change.
7.6
RETENTION OF RECORDS
Records and documents pertaining to the conduct of this study and the distribution of 
IMP, including eCRFs, ePRO data (if applicable), ICFs, laboratory test results, and 
medication inventory records, must be retained by the Principal Investigator for at least 
15 years after completion or discontinuation of the study, or for the length of time 
required by relevant national or local health authorities, whichever is longer.  After that 
period of time, the documents may be destroyed, subject to local regulations.
No records may be disposed of without the written approval of the Sponsor.  Written 
notification should be provided to the Sponsor prior to transferring any records to 
another party or moving them to another location.

submission.  The final IRB/EC-approved Consent Forms must be provided to the 
Sponsor for HA submission purposes according to local requirements.
The benefit and risks associated with participation in this study is outlined and will be 
explained to the patient by the investigator. 
The ICF will contain a separate section that addresses the collection and use of the 
optional aqueous humor samples for optional exploratory research.  The investigator or 
authorized designee will explain to each patient the objectives of the exploratory 
research.  Patients will be told that they are free to refuse to participate and may 
withdraw their specimens at any time and for any reason during the 15-year storage 
period.  A separate, specific signature will be required to document a patient's 
agreement to allow the optional aqueous humor sample to be collected and used for 
exploratory research.  Patients who decline to participate will check a “no” box in the 
appropriate section and will not provide a separate signature.
Patients’ compensation for costs resulting from participation in the study 
(e.g., transportation) may be provided if allowed by national regulations. Subject to 
national regulations, arrangement for additional healthcare for patients who suffer from 
an adverse event as a result of participation will be explained and documented in the
ICF.
The Consent Forms must be signed and dated by the patient before his or her 
participation in the study.  The case history or clinical records for each patient shall 
document the informed consent process and that written informed consent was obtained 
prior to participation in the study.
The Consent Forms should be revised whenever there are changes to study procedures 
or when new information becomes available that may affect the willingness of the patient 
to participate.  The final revised IRB/EC and HA (if applicable)-approved Consent Forms

a Screening cannot occur earlier than 7 days after the last standard-of-care of ITV ranibizumab treatment in the study eye. 
b Patients randomized to Implant treatment arms will be scheduled at the conclusion of their randomization visit for their Implant insertion surgery 
(Day 1) on such a date that no less than 28 days and no more than 37 days have lapsed between the surgery and their the last standard-of-care
ITV ranibizumab treatment in the study eye, unless a patient needs more time to interrupt aspirin or NSAID usage 7 days before Day 1 (see 
Section 4.3.2.3).  For these patients, Day 1 study treatment visit must occur no later than 45 days after the patient’s last ITV ranibizumab 
treatment.  In the case of a pause of enrollment and implant insertion surgeries, patients who have been randomized but have not yet received 
the study drug must repeat all randomization assessments (except for the randomization transaction in IxRS) after enrollment and implant 
insertion surgeries recommence, before receiving the study drug.

Month 9, Month X, Safety Visits, and Final/Early Termination Visits (cont.)
Ranibizumab Port Delivery System—Genentech, Inc.
121/Protocol GX28228, Version 8
c Implant treatment arms safety assessment visits will be scheduled on Days 2, 7 (2 days), and 14 (2 days) after Implant insertion; 7 (2) days 
after each Implant refill; 1 and 7 (2) days post-explantation if a patient is continuously followed in the study (prior to study Last Patient In 
Month 9 visit); and 1, 7(2), 30 (7), and 60 (7) days post-explantation if a patient is exiting the study, after which a patient will be scheduled 
for the early termination visit 30 (7) days later.
d After completion of the Month 9 visit, the Implant arms study patients will continue monthly study visits according to Month X (i.e., Month 10, 
Month 11, Month 12, etc.) schedule of assessments until the Sponsor decides, based on the primary analysis results, to either terminate the 
study and discontinue study treatment, or offer patients entry into the RPDS Extension Study.
e For patients who are completing the study or withdrawing early, perform 90 (7) days after the Implant explantation.
f
MacTSQ should be interviewer-administered by site personnel (other than VA examiner) prior to any other study procedures.
g Refer to the IxRS Manual for further details.
h Vital signs consist of blood pressure and pulse measurement.  Height and weight will also be performed at the screening visit.  On the visits 
when a patient receives treatment, including Day 1 visit, perform vital signs measurements pre-treatment.  On the day of implant insertion and 
explantation of procedure, blood pressure must also be recorded during surgery and upon completion of the surgery. 
i
Obtain from all study patients pre-treatment and prior to fluorescein angiography, if applicable.  For a description of the laboratory assessments 
to be performed, see Section 4.6.6 or the separate laboratory manual.
j
Perform urine pregnancy test prior to fluorescein angiography (if applicable) for women of childbearing potential, including those who have had 
tubal ligation. If the urine pregnancy test is positive, collect serum pregnancy sample and do not perform fluorescein angiography or study 
treatment until the final results are available. If the serum pregnancy test is positive, do not administer the study treatment.
k Collect and perform locally the urine pregnancy test prior to fluorescein angiography and/or study treatment (if applicable) for women of 
childbearing potential, including those who have had tubal ligation. If urine pregnancy test is positive, collect serum pregnancy sample and do not 
perform study treatment until the final results are available. If the serum pregnancy test is positive, do not administer the study treatment.
l
May be collected up to 1 day prior to day 1.
m Collect serum PK sample from Implant arms patients at each post explantation safety visit (see protocol Section 4.7.2 and Section 4.7.3).
n Collect serum PK sample for ranibizumab concentration from Implant treatment arms patients at the Randomization visit and then at each 
monthly visit PRIOR to the treatment, even if treatment is not subsequently given.

o Collect serum PK sample for ranibizumab concentration from Implant treatment arms patients ≥ 60 minutes post treatment on Day 1 visit (if 
possible) and then on Days 2, 7(2 days), and 14 (2 days) after Day 1 visit; afterwards collect serum PK sample 1 and 7 (2) days after each 
refill.  Collect a serum PK sample at the early termination visit if applicable.  Note:  for patients who are unable to visit the clinic for the PK 
sample collection 1 day after each Implant refill, provision will be made for this timepoint sample collection to be collected at their home.  
Alternatively, the sample may be collected 2 days after the refill.  Training will be provided to site staff on how to perform this task.  The sample 
will be sent to a central laboratory.
p Perform only if possible.
q Obtain serum anti-ranibizumab antibody sample from the Implant treatment arms patients prior to the study treatment and prior to fluorescein 
angiography (if applicable) on the Randomization visit, Visits Day 14, Month 1, 3, 6, and 9 and at the early termination visit if applicable.
r
If a patient has consented to this optional sample collection, obtain the aqueous humor sample prior to or immediately following one or more 
refills and at the Day 7 safety visit post refill.
s Perform low luminance BCVA testing after standard BCVA testing.
t
Perform only if you have the Humphrey Visual Field machine at your site.  In addition to the listed timepoints, this testing will be performed any 
time the patient reports a new defect of the peripheral vision. 
u If it cannot be performed during Randomization, this testing must be performed on a subsequent day but before Day 1.
v Perform only if you have ultrasound or optical biometry capability at your site.
w Perform pre-treatment.
x Should be performed in the surgical center using Tono-Pen tomometry prior to the Implant insertion surgery.
y Dilated ophthalmoscopy examinations will be performed for patients in the Implant treatment arms after Implant insertion in the study eye at the 
Day 1 visit, and then on Days 2, 7 (2 days), and 14 (2 days) after the Day 1 visit; afterward, perform dilated ophthalmoscopy examinations at 
each monthly visit to monitor the Implant and its release control element for visible clogging and other Implant problems.
z Historical OCT taken at the time of diagnosis of nAMD will also be required to determine patient’s eligibility at the screening visit.  If fluorescein 
angiograms were taken at the time of diagnosis of nAMD, they must be submitted to the reading center as well. If available, historical fluorescein 
angiograms will be evaluated by the reading center, but are not required to determine patient’s eligibility.  Refer to the Reading Center Manuals 
for details.
aa The central reading center will evaluate fundus photography, fluorescein angiograms, and SD-OCT taken at the screening visit for determination 
of a patient’s eligibility, together with the historical OCT taken at the time of diagnosis of nAMD. Refer to the Reading Center Manual for details.
ab Only at selected sites. Perform pre-treatment.
ac In addition to the timepoints listed, the photo will also be taken at any visit if there are concerns with Implant function.

ad The pre-Implant insertion or explantation use of self-administered antimicrobials is required.  The pre-Implant refill use of self-administered 
antimicrobials is per the investigator’s discretion. The post-Implant insertion, explantation, or refill use of self-administered antimicrobials is 
required.
ae The video of the implant/explant procedure (if applicable) should be recorded. The video of the refill is optional.
af Initially fill the Implant with IxRS assigned kit of ranibizumab prior to its insertion into the study eye.  Afterwards, starting at Month 1 visit, if refill 
criteria are met (see Section 3.1.1), refill the Implant with IxRS assigned ranibizumab kit.
ag Following each Implant refill, patients will have a finger counting test, followed by hand motion and light perception tests (when necessary) 
performed by the physician within 15 minutes post-treatment for the study eye only; the patients will remain at the clinic for approximately 
40 minutes.  If there are no safety concerns 40 (10) minutes following treatment, the patient will be allowed to leave the clinic.  If any safety 
concerns or immediate toxicity is noted, the patient will remain at the clinic and will be treated according to the designated physician’s clinical 
judgment.  If applicable, the adverse event will be reported on the appropriate eCRF page.  
ah Upon completion of the Implant insertion or explantation procedure, patients will have indirect ophthalmoscopy performed to monitor the Implant 
placement and to evaluate any potential Implant problems.  Intraocular pressure will be checked for the study eye only by the treating physician 
by digital palpation.  These assessments must be performed prior to placing a patch on the eye.  If any safety concerns or immediate toxicity is 
noted, the patient will remain at the surgical center and will be treated according to the designated physician’s clinical judgment.  If applicable, 
the adverse event will be reported on the appropriate eCRF page.
ai Follow Refill Needle return instructions from the laboratory manual if Implant refill has been performed (if applicable).
aj Upon completion of the Implant insertion procedure, complete the Implant insertion evaluation to indicate surgical details of the insertion 
procedure. Information captured in the evaluation will be reported on the appropriate eCRF page.
ak Record any concomitant medications (i.e., any prescription medications or over-the-counter preparations other than protocol-specified 
procedural medications, and pre-treatment and post-treatment medications, such as proparacaine, antimicrobials) used by the patient within 
7 days preceding the randomization visit date and through the conclusion of the patient’s study participation or early termination visit.
al After informed consent has been obtained but prior to initiation of study treatment, only serious adverse events related to a protocol-mandated 
intervention (e.g., procedures such as fluorescein angiography, medication wash-out, etc.) should be reported.  Adverse events will be recorded 
starting on Day 1 through the last study visit.  Adverse events assessed by the qualified ophthalmologist as related to Implant 
insertion/refill/explantation should be followed until the event resolves or the event is assessed as irreversible, chronic, or stable, even if the 
patient’s participation in the study is over.
am Record all concurrent ocular procedures or additional assessments performed on the study or fellow eye. Results of the additional ocular 
assessments must be forwarded to the Sponsor for evaluation and/or storage.

Appendix 8
Preparation and Administration of Ranibizumab ITV Injection
The physician will prepare the ranibizumab injection as outlined below.
Vials of ranibizumab in aqueous humor solution should remain refrigerated at 2C to 8C 
(36F to 46F) until just prior to use.  DO NOT FREEZE vials.  Protect from direct light.  
Do not use beyond the expiration date.  In order to minimize the risk of microbial growth, 
dose solutions should be prepared immediately before dosing.  Dose solutions are for 
single use only.
After preparing the study eye as outlined in Appendix 7, withdraw 0.2-mL ranibizumab 
dose solution through a 5-m filter needle.  Remove the filter needle, replace it with a 
30-gauge, 1/2-inch Precision Glideneedle, and expel excess ranibizumab so that the 
syringe contains 0.05 mL of solution.  Insert the syringe through an area 3.5 to 
4.0 mm posterior to the limbus, avoiding the horizontal meridian, and aiming toward the 
center of the globe.  The injection volume should be delivered slowly.  The needle 
should then be removed slowly to ensure that all drug solution is in the eye.  The scleral 
site for subsequent intravitreal injections should be rotated.  Refer to Appendix 9, 
for detailed post-injection procedures.
All injection materials (i.e., syringes, needles) will be discarded in a sharps container 
immediately following each ranibizumab injection.  
A patient’s study eye will be monitored with a finger count test within 15 minutes of the 
ranibizumab injection by the physician.  A measurement of IOP in the study eye will be 
obtained 40 (10) minutes post-injection. If there are no safety concerns, the patient will 
be allowed to leave the clinic.  If any safety concerns or immediate toxicity is noted, the 
patient will remain at the clinic and will be treated according to the designated 
physician’s clinical judgment.  The following table provides specific instructions for the 
preparation and administration of ranibizumab in aqueous humor solution.

Best Corrected Visual Acuity Testing
SCOPE
Best corrected visual acuity (BCVA) will be measured by trained and certified personnel 
at the study sites.  The visual acuity (VA) examiner will be masked to the patient study 
eye assignment and patient treatment assignment.  The VA examiner will have no 
access to a patient’s previous visits’ VA scores; the VA examiner will only be aware of
the patient’s refraction data from previous visits.  The VA examiner is not permitted to 
perform any other tasks involving direct patient care except for VA refraction and VA 
examination.  VA will be measured at the intervals specified in the protocol (see 
Section 4.6 of the protocol and Appendix 1 and Appendix 2).  
EQUIPMENT
The following is needed at minimum to conduct the examination:

Examination lane of adequate dimensions to allow testing at required distances

Standard chair with a firm back

Set of three Precision Visionor Lighthouse distance acuity charts (modified Early 
Treatment Diabetic Retinopathy Study Charts 1, 2, and R)

Retro-illuminated box

Trial frame

Trial lens set
TRAINING AND CERTIFICATION
A VA specifications document, procedure manual, and training materials will be provided 
to the investigational sites, and VA examiner certification will be obtained.  The VA 
examination room also must be certified before any VA examinations are performed. If 
new VA personnel or VA rooms are added to the study, certification must be obtained 
prior to performing study assessments.

Low Luminance Best Corrected Visual Acuity Testing
There are the same requirements as the best corrected visual acuity described in 
Appendix 10; however, the low luminance visual acuity will be measured by placing a 
2.0-log-unit neutral density filter over the best correction for that eye and having the 
participant read the normally illuminated Early Treatment Diabetic Retinopathy Study 
chart.

Grading Scales
GRADING SCALE FOR ANTERIOR CHAMBER FLARE OR CELLS
Flare
0
No protein is visible in the anterior chamber when viewed by an experienced observer 
using slit-lamp biomicroscopy; a small, bright, focal slit-beam of white light; and high 
magnification.
Trace
Trace amount of protein is detectable in the anterior chamber:  This protein is visible 
only with careful scrutiny by an experienced observer using slit-lamp biomicroscopy; a 
small, bright, focal slit-beam of white light; and high magnification.
1
Slight amount of protein is detectable in the anterior chamber:  the presence of protein 
in the anterior chamber is immediately apparent to an experienced observer using 
slit-lamp biomicroscopy and high magnification, but such protein is detected only with 
careful observation with the naked eye and a small, bright, focal slit-beam of white 
light.
23
Moderate amount of protein is detectable in the anterior chamber.  These grades are 
similar to 1but the opacity would be readily visible to the naked eye of an observer 
using any source of a focused beam of white light.  This is a continuum of moderate 
opacification, with 2being less apparent than 3.
4
A large amount of protein is detectable in the anterior chamber.  This grade is similar 
to 3, but the density of the protein approaches that of the lens.  Additionally, frank 
fibrin deposition is frequently seen in acute circumstances.  It should be noted that 
because fibrin may persist for a period of time after partial or complete restoration of 
the bloodaqueous humor barrier, it is possible to have resorbing fibrin present with 
lower numeric assignations for flare (e.g., 1flare with fibrin).
Cells
0
No cells are seen in any optical section when a large slit-lamp beam is swept across 
the anterior chamber.
Trace
Few (13) cells are observed when the slit-lamp beam is swept across the anterior 
chamber.  When the instrument is held stationary, not every optical section contains 
circulating cells.
1
310 cells/optical section are seen when the slit-lamp beam is swept across the 
anterior chamber.  When the instrument is held stationary, every optical section 
contains circulating cells.
2
1025 cells are seen when the slit-lamp beam is swept across the anterior chamber.  
When the instrument is held stationary, every optical section contains circulating cells.
3
2550 cells are seen when the slit-lamp beam is swept across the anterior chamber.  
When the instrument is held stationary, every optical section contains circulating cells.  
Keratic precipitates or cellular deposits on the anterior lens capsule may be present.
4
More than 50 cells are seen when the slit-lamp beam is swept across the anterior 
chamber.  When the instrument is held stationary, every optical section contains cells, 
or hypopyon is noted.  As for fibrin deposition, hypopyon may persist for some period 
of time after the active exudation of cells into the anterior chamber has diminished or 
ceased entirely, making it possible to have 1circulating cells in the anterior chamber 
with a resolving hypopyon.

Central Laboratory Sample Collection and Shipping 
BIOLOGICAL SAMPLES
Serum for assessment of laboratory safety (hematology, serum chemistry, coagulation, 
pregnancy test) and urinalysis will be collected at screening visit.  Urine pregnancy test 
will be collected and performed at Day 1 prior to each treatment for women of 
childbearing potential, including those who have had tubal ligation. If positive, serum
pregnancy test will be performed.  If the serum pregnancy test is positive, the study 
treatment will be discontinued.  Serum for assessment of ranibizumab concentrations 
(pharmacokinetics) and anti-ranibizumab antibodies, residual content of the Implant from 
the Refill Needle (if applicable), and aqueous humor or vitreous samples (at the start of 
explantation for patients undergoing an explantation procedure) will be collected at the 
timepoints specified in Section 4.6.6 of the protocol and the schedule of assessments
(see Appendix 1 and Appendix 2).  The optional aqueous humor samples prior to one or 
more refills and at the Day 7 safety visit post refill will be collected as well.
All samples should be collected and shipped initially to the central laboratory.  The 
laboratory safety (hematology, serum chemistry, coagulation, and urinalysis) samples 
will be analyzed by the central laboratory.  The rest of the collected samples will be 
analyzed by Sponsor or selected designee. All necessary transfer tubes, labels, forms, 
and shipping supplies will be provided by the central laboratory.   
OPTIONAL ANTERIOR CHAMBER (AQUEOUS HUMOR) SAMPLE 
COLLECTION FROM IMPLANT TREATMENT ARMS
The optional aqueous humor paracentesis samples will be collected from patients who 
consent to the procedure and sample acquisition.  An aqueous humor sample will be 
collected prior to or immediately following the patient’s study eye treatment visits as 
indicated in Appendix 1.  The aqueous humor sample collection consists of an anterior 
chamber paracentesis (removing 0.05 to 0.1 mL of fluid from the anterior chamber of the 
eye).
The anterior chamber paracentesis will be performed by a qualified physician by placing 
a drop of topical anesthetic on the cornea, passing a 30-gauge needle through the 
limbus into the anterior chamber and removing 0.05 to 0.1 mL of aqueous humor fluid.  
Samples will be collected with the kit provided by central laboratory and shipped on dry 
ice to the central laboratory as soon as possible after the draw.
For administration of study treatment to ITV arm patients following the collection of the 
aqueous humor sample, the subconjunctival lidocaine anesthetic must be injected into 
the eye prior to study treatment.

Appendix 20
Central Laboratory Sample Collection and Shipping (cont.)
Ranibizumab Port Delivery System—Genentech, Inc.
183/Protocol GX28228, Version 8
EYE FLUID SAMPLE COLLECTION FROM IMPLANT TREATMENT ARMS
Vitreous or aqueous humor sample collection must be performed at the start of 
explantation for all patients undergoing an explantation procedure.  The choice between 
vitreous collection or aqueous humor collection is per investigator’s discretion.  

The aqueous humor sample collection consists of an anterior chamber paracentesis 
(removing 0.050.1 mL of fluid from the anterior chamber of the eye).

The vitreous humor sample collection consists of a vitreous tap (removing 
0.050.1 mL of undiluted vitreous from the central vitreal cavity).
The vitreous humor sample collection will be performed by a qualified physician using
standard 23-gauge or 25-gauge vitrectomy procedures.  The infusion cannula will be 
inserted through a sclerotomy in the pars plana of the infero-temporal quadrant of the 
eye, without opening the infusion.  The vitreous humor tap will be performed by placing 
the vitrectome in the central vitreous through a second sclerotomy in the pars plana of 
the supero-nasal quadrant of the eye, and by aspirating 0.05 to 0.1 mL of undiluted 
vitreal sample with a 5-mL syringe while cutting vitreous actively.  After collecting 
enough vitreous humor sample, the aspiration will be stopped and the vitrectome will be 
carefully removed from the eye.  
After collecting the undiluted vitreous humor sample, the Implant will be removed from 
the eye and the scleral wound will be sutured as described in the RPDS IFU.  In case of 
hypotony, the infusion through the cannula will be opened to restore the normal 
intraocular pressure.  The physician will then perform a careful exploration of the retina, 
and a standard vitrectomy will be performed in the case of visible retinal detachment or 
other complications that require immediate surgical intervention.
Vitreous or aqueous humor samples will be collected with the kit provided by the central 
laboratory and shipped on dry ice to the central laboratory as soon as possible after the 
draw.  Please see the RPDS IFU for further details.
EXPLANTED IMPLANTS WITH CONTENTS
Explanted Implants containing ranibizumab drug product will be preserved for potential 
analysis upon explant procedure.  A method to retrieve the contents from explanted 
Implants is in place and protocols to characterize drug product are under development.  
In addition, the explanted Implants may undergo physical inspection and/or functional 
testing.
Refer to the Study Manual for detailed sample collection, storage, and shipping 
instructions.  All necessary transfer tubes, Vacutainers, labels, shipping boxes, 
and forms will be provided by the central laboratory.

1. 
GENERAL 
The Ranibizumab Port Delivery System (RPDS) Device Clinical Investigational Plan (CIP) 
describes the data that will be extracted from the Phase II study (GX28228) that is being 
conducted with the RPDS in order to assess its safety and performance. This CIP also 
focuses on the endpoints and analyses that will demonstrate that the RPDS works as 
intended. The purpose of the CIP is to comply with the International Organization for 
Standardization (ISO) 14155 standard "Clinical investigation of medical devices for 
human subjects", to assess the Implant safety and performance. The CIP will also be 
used  to support obtaining a Conformité Européenne (CE; European Conformity) 
certificate, which is necessary for regulatory approval in the European Economic Area. 
This CIP is intended to complement the Phase II pivotal study, which will collect the 
clinical information needed to fulfill the Essential Requirements of the European Medical 
Device Directive. Data are collected as part of the Phase II protocol. This CIP is 
specifically designed to investigate the functionality of the Implant while the ancillary 
devices’ functionality will mainly be demonstrated as part of engineering/ design 
verification testing and human factor engineering studies. 
Age-related macular degeneration (AMD) is a chronic disorder of the macula and is the 
most common cause of irreversible vision loss in older Americans and Europeans. AMD 
is categorized into two subtypes, dry and wet, based on clinical examination, ocular 
imaging, and pathologic findings. Dry AMD represents approximately 80% to 90% of 
AMD cases. In approximately 10% of dry AMD cases, a conversion to wet, or 
neovascular, AMD occurs over time. Although wet AMD is comparatively rare, prior to 
the development of anti-vascular endothelial growth factor (anti-VEGF) therapy, it 
accounted for the majority of severe vision loss from AMD. Central vision loss is painless 
and emerges gradually or suddenly (Bressler 1995; Klein et al. 1997). 
Ranibizumab, a recombinant, humanized monoclonal antibody fragment (Fab), which 
binds to all known isoforms of VEGF-A, was first registered for use in neovascular wet 
AMD in the United States on 30 June 2006 and in the European Union on 22 January 
2007 and has a well-established efficacy and safety profile. 
Ranibizumab is approved for the treatment of wet AMD, macular edema secondary to 
retinal vein occlusion, diabetic macular edema (DME), and diabetic retinopathy in DME. 
In the European Union, ranibizumab is also approved for the treatment of choroidal 
neovascularization due to pathological myopia. The primary treatment modality is 
injection of ranibizumab into the vitreous humor of the patient’s eye. 

Ranibizumab Port Delivery System—Genentech, Inc. 
196/Protocol GX28228, Version 8 
Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
 
Ranibizumab is injected directly into the vitreous humor of the eye. Intravitreal (ITV) 
injections of ranibizumab have shown efficacy in treating these ocular diseases, however, 
a drug delivery system that could reduce the burden of regular, often monthly, injections 
while maintaining satisfactory clinical outcomes is desired. Ranibizumab has been 
studied extensively to date and treatment with ITV injection has been demonstrated to be 
effective in preventing vision loss associated with VEGF-related retinal disorders. For 
many patients with VEGF-driven ocular diseases, long-term managment involving 
frequent, repeated ranibizumab ITV injections and monitoring visits is required. 
Frequent clinic visits can place a significant burden on the patients and their caregivers 
as well as treating physicians and the healthcare system. 
Administration of ranibizumab through an intra-ocular implant with a drug reservoir and a 
controlled release element may enable sustained delivery over extended periods of time, 
to substantially reduce the number of ITV injections while achieving similar efficacy to 
monthly injections. This decrease in treatment burden could reduce the risk from ITV 
injection-related adverse events (AE), increase treatment compliance, and reduce the 
burden to patients, their caregivers, and the healthcare system while maintaining 
optimum visual outcomes. 
2. 
IDENTIFICATION AND DESCRIPTION OF THE 
INVESTIGATIONAL DEVICE 
The RPDS is a novel, investigational intraocular drug delivery system designed to be 
used specifically with ranibizumab. The system consists of an intraocular Implant along 
with four ancillary devices. 
The Implant is a refillable drug reservoir. It is filled with ranibizumab before it is inserted 
into the eye through the pars plana. The Implant is secured within the sclera, with an 
injection port that remains visible through the conjunctiva following insertion. Once filled 
with ranibizumab, the Implant is designed to provide sustained release of ranibizumab for 
the treatment of patients with neovascular wet AMD. The Implant can be refilled with 
ranibizumab in situ via an injection through the conjunctiva and Implant septum. 
The RPDS consists of five components: 
• 
Implant 
• 
Insertion Tool 
• 
Initial Fill Needle 
• 
Refill Needle 
• 
Explant Tool

2.1 
SUMMARY DESCRIPTION OF THE INVESTIGATIONAL DEVICE 
AND ITS INTENDED PURPOSE 
2.1.1 
Implant 
The Implant is designed to deliver ITV ranibizumab via sustained release over the course 
of at least 4 months and is intended to be refilled multiple times through a septum in the 
Implant. The primary mode of action of the combination product is provided by the drug, 
ranibizumab. 
The Implant is intended for surgical placement through the pars plana of the eye (see 
Figure 1). The distal end of the Implant extends into the vitreous humor with the proximal 
end accessible through the conjunctiva. When in place, an injection port is visible 
through the conjunctiva, and ranibizumab is refilled into the Implant through a septum that 
is in contact with the conjunctiva, thus not requiring repeat penetration of the sclera or 
choroid. The Implant is designed to contain approximately 20 µL of ranibizumab solution 
when filled. 
The rate of ranibizumab release from the Implant into the vitreous is controlled by 
passive, concentration gradient-driven molecular diffusion through the porous distal end 
of the Implant. This porous barrier, known as the Release Control Element (RCE), allows 

Ranibizumab Port Delivery System—Genentech, Inc. 
198/Protocol GX28228, Version 8 
Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
 
molecules to diffuse at a rate dependent on the diffusivity of the molecule and the 
concentration gradient across the RCE. 
The Implant is filled with ranibizumab solution with a custom Initial Fill Needle prior to 
insertion.  After placement of the Implant, subsequent injections are performed with a 
custom Refill Needle that allows for the exchange of the contents of the Implant (residual 
ranibizumab, vitreal components) with the new ranibizumab solution. 
The Implant is presented below in Figure 2. No material or design changes are expected 
after the clinical batch release of the Phase II Implant. 
Figure 2 Implant 
 
 
The Implant is a refillable reservoir designed for intravitreal insertion through the pars 
plana. The Implant consists of four primary components (Figure 2): 
• 
Extrascleral flange 
• 
Septum 
• 
Body 
• 
RCE 
 

Ranibizumab Port Delivery System—Genentech, Inc. 
199/Protocol GX28228, Version 8 
Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
 
Once inserted in the eye, the body and the release control element of the Implant extend 
into the vitreous cavity, while the flange anchors the Implant within the sclera. 
The extrascleral flange provides secure anchoring of the Implant within the sclera and is 
encased in silicone. 
The septum is a self-sealing interface through which ranibizumab is injected into the 
Implant both prior to insertion and during subsequent refills in situ. 
The body of the Implant contains the drug reservoir, which holds approximately 20 µL of 
drug. The Implant arrives with an empty reservoir. The reservoir is filled with ranibizumab 
by the surgeon immediately prior to insertion of the Implant into the eye. 
The RCE controls the rate of ranibizumab diffusion from the drug reservoir into the 
vitreous. 
The Implant is packaged in a sterile blister. 
2.1.2 
Initial Fill Needle 
The Initial Fill Needle is a needle designed to fill the Implant with ranibizumab prior to 
Implant insertion. The Initial Fill Needle consists of five primary components (Figure 3): 
• 
Needle (33-gauge) 
• 
Soft stop 
• 
External hub 
• 
Luer hub 
• 
Blue cap 
 
The needle contains a specialized external hub. This hub will be used to guide the 
syringe along the needle guide channel of the Insertion Tool so that the needle tip will be 
properly aligned with the Implant septum for Implant filling. 
The soft stop surrounds the needle at the junction of the needle and the external hub. 
The soft stop provides a seal with the septum during Implant filling. 
The Initial Fill Needle is packaged in a sterile pouch.

Insertion Tool 
The Insertion Tool is a handheld ophthalmic instrument designed to facilitate handling of 
the Implant during the initial filling and insertion procedures. The Insertion Tool consists 
of four primary components (Figure 4): 
• 
Insertion Tool tips 
• 
Finger grips 
• 
Stainless steel shafts 
•

2.1.4 
Refill Needle 
The Refill Needle is designed to simultaneously exchange the contents of the Implant 
reservoir with new ranibizumab in situ. The Refill Needle consists of five primary 
components (Figure 5): 
• 
Vented needle (34-gauge) 
• 
Soft stop 
• 
Fluid collection reservoir 
• 
Luer hub 
• 
Clear cap 
 
The vented needle and fluid collection reservoir enable exchange of ranibizumab 
between the Implant and the refill syringe. As fresh drug solution is injected into the 
Implant through the needle, fluid remaining in the Implant flows through openings in the 
vented needle and is collected into the fluid collection reservoir. 
The soft stop provides a non-traumatic contact surface between the conjunctiva and the 
Refill Needle during Implant refilling. 
The Refill Needle is packaged in a sterile blister.

Explant Tool 
The Explant Tool consists of a set of forceps with contoured tips. The contoured tips are 
designed to grasp underneath the Implant flange and securely pull the Implant for 
explantation (Figure 6). 
The Explant Tool is packaged in a sterile blister.

sterilization and insertion, b) assist with filling of the Implant before insertion, and c) 
enable insertion of the Implant through a pars plana sclerectomy. 
• 
Initial Fill Needle: The Initial Fill Needle is a 33-gauge Luer-Lock needle designed to 
perform the initial fill of the Implant while the Implant is held in the Insertion Tool. 
• 
Refill Needles: The Refill Needle is a Luer-Lock needle designed to simultaneously 
exchange (in situ) any remaining old drug product in the Implant reservoir with new 
drug product. 
• 
Explant Tool: The Explant Tool is designed to enable the removal of the Implant 
from the posterior segment of the eye after resection of the conjunctiva and removal 
of any scar tissue.

SUMMARY OF THE NECESSARY TRAINING AND EXPERIENCE 
NEEDED TO USE THE INVESTIGATIONAL DEVICE SYSTEM 
The RPDS is intended for use by vitreoretinal surgeons, scrub nurses, other 
hospital/clinic staff, and patients. Study investigators will be qualified ophthalmologists 
trained in the management of retinal diseases and ocular surgery, and will be certified by 
a Sponsor-selected vendor to perform initial Implant fill, insertion, refill, and explantation. 
The surgical procedures involved in the use of the RPDS are detailed in the RPDS IFU. 
Scrub nurses will assist the surgeon in selected preparation tasks. Other hospital and 
clinic staff will perform routine tasks outside of the sterile field, such as receipt or storage 
of the product. Patients will retain the Implant for an extended period of time. 
2.9 
DESCRIPTION OF THE SPECIFIC MEDICAL OR SURGICAL 
PROCEDURES INVOLVED IN THE USE OF THE 
INVESTIGATIONAL DEVICE 
Patients in the Implant treatment arms will have the Implant, prefilled with ranibizumab, 
surgically inserted into the study eye at the Day 1 visit and subsequently refilled at 
monthly visits only if the protocol-specified refill criteria are fulfilled. The insertion and 
explantation procedures must be performed in the surgery room while the refill procedure 
is permitted in the physician office setting. 
The Implant is surgically placed through the pars plana to allow for a sustained delivery 
of ranibizumab into the vitreous. As the Implant insertion is a surgical procedure that is 
performed in an operating room, sterile controls must be in place to minimize the risk of 
ocular infection. The Implant is filled with approximately 20 µL of ranibizumab 
immediately prior to insertion of the Implant into the patient’s study eye. 
In addition to standard pre-operative instructions used in practice, patients will be 
instructed to apply topical antimicrobial ophthalmic drops to the ocular surface 4 times 
within 24 hours prior to the procedure. 

Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
Ranibizumab Port Delivery System—Genentech, Inc. 
209/Protocol GX28228, Version 8 
 
At each refill, a volume of approximately 100 µL of ranibizumab will be injected in situ into 
the Implant through the septum to exchange the remaining contents of the Implant with 
newly introduced ranibizumab.  During the refill procedure, the contents of the Implant 
will be collected in the fluid collection reservoir of the Refill Needle. The volume of newly 
introduced ranibizumab remaining in the Implant after the refill procedure will be 
approximately 20 µL 
The Implant has undergone design verification confirming Implant performance through 
the expected use life, including 93 punctures of the Implant septum for Implant refills. 
For detailed instructions on the Implant initial fill, insertion, refill, and explantation 
procedures, refer to the RPDS IFU. 
3. 
JUSTIFICATION FOR THE DESIGN OF THE CLINICAL 
INVESTIGATION 
The Phase II study is being conducted to determine the dose of ranibizumab that is both 
efficacious for patients and allows for a dosing schedule that is less frequent than 
monthly ITV injections. While the design and sample size of this clinical study is aiming 
at the determination of an appropriate dosing regimen for the drug ranibizumab delivered 
through the Implant, this study will also appropriately inform the safety and performance 
of the Implant in human subjects. 
This RPDS CIP will document whether the Implant and ancillary devices “work as 
intended.” 
The data extraction and analysis will allow documenting the following aspects: 
• 
Establish that there is no evidence of Implant clogging in more than 10% of patients 
in the Implant arms at Month 9 
• 
Demonstrate that the AE profile observed when using the Implant is clinically 
acceptable as compared with ranibizumab dosed using conventional ITV injection. In 
other words, any complications associated with Implant insertion, refill, or 
explantation, or associated with the long term presence of the Implant within the 
posterior chamber of the eye, are manageable and acceptable in an overall benefit-
risk assessment versus ITV dosing. 
 
This will include a characterization of the “Prespecified RPDS-associated AEs”, i.e., 
those adverse device effects (ADEs) that have been pre-specified as being most relevant 
for the risk assessment of the Implant and the procedures of Implant insertion, refill, and 
explantation. 

Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
Ranibizumab Port Delivery System—Genentech, Inc. 
210/Protocol GX28228, Version 8 
 
For each AE (including “Prespecified RPDS-associated AEs”) observed during the clinical 
study, the case report form (CRF) will collect a separate assessment of investigator 
causality for each “study intervention” element (i.e., investigator causality for “drug”, 
investigator causality for “procedures”, and investigator causality for Implant or ancillary 
devices). Investigators will be trained on the requirement to assess each AE for potential 
causal association to “drug”, “procedure”, Implant or ancillary devices – so that they may 
determine whether there is a causal association with one, more than one, or none of the 
“Study intervention” elements. 
• 
Particular focus will be paid to evaluate the safety of the RPDS, as measured by 
“Prespecified RPDS-associated AE” (see protocol Section 6.5.1) 
 
The RPDS CIP will evaluate whether the Implant is failing to operate as intended. As a 
passive diffusion device, the Implant can only operate in four different states as shown in 
Table 6. 
Table 6 
Operation States for the Implant 
Implant Operational States 
Ability to Detect State in Human Study 
Failure to Operate State 1: 
RCE is clogged and no drug 
diffuses from reservoir 
High detectability 
Will be apparent as deterioration in visual function and the 
development of further disease activity in a patient who had 
responded to ITV ranibizumab prior to the Implant insertion. 
The Implant will be assessed for possible clogging if the 
Implant is explanted. For a full description of the assessments 
refer to CIP section 5.3 
Failure to Operate State 2: 
RCE rapidly elutes drug from 
the reservoir 
Low detectability in humans 
The proportion of “failure to operate state 2” will be based upon 
bench testing with the Implant, as this is anticipated to be a 
very rare event with clinically implanted devices. 
It would be difficult to reliably observe a typical PK profile for 
this failure mode in a clinical study due to the potential high 
variability of the PK measurement. 
Clinically, the patient would be expected to require frequent 
refill. From previous high dose ITV studies, no safety signals 
have been identified that would be indicative of high ITV drug 
levels. 
Therefore, this failure mode is best evaluated as part of bench 
testing after explantation. 

Appendix 21

Implant Operational States 
Ability to Detect State in Human Study 
Failure to Operate State 3: 
RCE elutes too slowly 
Low detectability in humans 
This will be based upon bench testing with the Implant. A 
target release rate of 4 µg/day and a vitreous concentration no 
lower than 12 µg/mL is currently established in the 
specifications. 
Implant Operational States 
Ability to Detect State in Human Study 
Successful Operation: 
Drug diffuses across RCE in a 
manner consistent with Fick’s 
Law of Diffusion as 
demonstrated in bench and 
animal studies. 
No direct detectability in humans of Implant functionality 
can be shown 
Implant functionality is demonstrated best in bench studies. It 
cannot be demonstrated in humans because there is no ethical 
method for directly measuring the flow of drug into the vitreous 
and serum pharmacokinetics is seen as too variable a 
measurement. 
CIP = Clinical Investigational Plan; ITV = intravitreal; PK = pharmacokinetic; RCE = release 
control element 
 
This RPDS CIP is not designed to determine a therapeutic dosing regimen for 
ranibizumab. It will determine whether the Implant meets an acceptable rate of failure to 
Operate State 1. 
The Implant is a passive diffusion device, so it cannot act outside of its native physics. It 
must diffuse the drug in accordance with Fick’s Law. Bench studies, in models of the 
ocular environment, are the most effective ways to document the rate of drug diffusion 
from the Implant. As a result, it is deemed unnecessary to directly measure the flow of 
ranibizumab from the Implant in humans. In addition, there is no appropriate method to 
directly measure the flow of ranibizumab from the Implant in humans. No direct 
monitoring of drug levels in the reservoir or vitreous would be ethical in humans as there 
is no benefit to an individual patient that would balance the risk of these repeated 
invasive collections of vitreous. There is no method for monitoring the drug levels in the 
Implant reservoir. 
Additionally, measurement of serum ranibizumab cannot provide quantitative data for the 
Implant diffusion. Serum ranibizumab concentration-time data are remote from the site of 
drug release (Implant vitreous  serum) and therefore are not a direct quantitative 
measurement of the drug release rate from the Implant. In addition, serum 
pharmacokinetics have high intersubject variability when administered by the ITV route; 
similar variability is expected by the Implant route. This may also confound the use of 
serum pharmacokinetics as a quantitative reflection of drug release from the Implant. 

Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
Ranibizumab Port Delivery System—Genentech, Inc. 
212/Protocol GX28228, Version 8 
 
This high variability was observed in the serum pharmacokinetic (PK) levels following 
refills in the Phase I human trial. Therefore, PK data will be collected in all patients in the 
Phase II study, but no clear conclusion on the Implant diffusion rate can be prespecified 
before results become available. 
It can be concluded that human studies will not provide better quantitative information 
about the diffusion rate of ranibizumab from the Implant than bench studies will. 
Adequate data have been generated in bench studies to demonstrate that the Implant will 
reliably diffuse ranibizumab in a controlled manner into the vitreous humor. 
3.1 
EVALUATION OF THE RESULTS OF THE RELEVANT 
PRECLINICAL TESTING/ASSESSMENT CARRIED OUT TO 
JUSTIFY THE USE OF THE INVESTIGATIONAL DEVICE IN 
HUMAN SUBJECTS 
The RPDS is a drug delivery system intended to release therapeutic levels of 
ranibizumab into the vitreous humor over an extended period of time. The RPDS 
includes three primary components: the drug (ranibizumab), the port delivery system 
permanent implant, and the ancillary devices. 
A comprehensive non clinical testing strategy was developed to support the clinical 
development (Phase II and Phase III) and registration of the Implant. The strategy 
included the assessment of the in vitro and in vivo functionality and biocompatibility of a 
prototype implant, Phase II Implant, and the ancillary devices. 
In vitro and in vivo biocompatibility studies were chosen based on direct and indirect 
interaction of the Implant and ancillary devices with ocular tissues and long-term ocular 
implantation, and are consistent with ISO 10993 (Biological evaluation of medical 
devices), ISO 11979-5 (Ophthalmic implants-intraocular lenses part 5: biocompatibility); 
and ANSI Z80.7 (Testing for intraocular lens devices). Biocompatibility testing is 
conducted with the finished Implant, and extracts from the Implant and ancillary devices. 
The nonclinical testing results are summarized in the RPDS IB Section 4.

3.2 
EVALUATION OF CLINICAL DATA THAT ARE RELEVANT TO 
THE PROPOSED CLINICAL INVESTIGATION 
The Implant has been investigated in a prospective, Phase I, open-label study in patients 
with wet AMD, conducted by FSV4 at a single site in Latvia. The study investigated the 
safety, tolerability, and duration of ranibizumab exposure delivered with the Implant. 
This Phase I Implant was composed of biocompatible materials (polymethyl 
methacrylate, silicone, 316L stainless steel). 
For details of the design of the Phase I study as well as the results, refer to protocol 
Section 1.3 and to the RPDS IB Section 5. 
4. 
RISKS AND BENEFITS OF THE INVESTIGATIONAL DEVICE 
AND CLINICAL INVESTIGATION 
The general approach to identifying, planning, and execution of the risk management 
activities of the Phase II RPDS is in accordance with ISO 14971:2007/2012: Medical 
devices – application of risk management to medical devices. 
Risk management plans have been created to cover the following: 
• 
Implant, Insertion Tool, Initial Fill Needle, Refill Needle, and Explant Tool 
• 
Labeling 
• 
Packaging manufacturing of the combination product (assembly operations) 
• 
Shipping and storage (e.g., product shipping, handling and storage) 
• 
Clinical trial surveillance (e.g., product monitoring and complaints) 
• 
Components not off-the-shelf (e.g., molding assembly components) 
 
The results of risk/benefit assessment from the overall risk analysis are described in the 
RPDS IB Section 6. 
4.1 
ANTICIPATED CLINICAL BENEFITS 
As a result of the chronic, progressive nature of wet AMD, frequent ranibizumab ITV 
injections continue for extended periods for many patients. Pivotal studies of 
ranibizumab in wet AMD (FV2598g and FVF2587g) demonstrated significant and well-
maintained visual acuity (VA) outcomes with monthly ITV injections for 2 years. In these 
studies it was observed that the treatment effect reaches, on average, a plateau after 
three consecutive monthly injections. Subsequently, there have been several studies 
evaluating a PRN treatment regimen, with different re-treatment criteria also showing 
early response after start of treatment (Busbee et al 2013; CATT Research Group 2011). 

Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
Ranibizumab Port Delivery System—Genentech, Inc. 
214/Protocol GX28228, Version 8 
 
In clinical practice, frequent office monitoring visits are required and regular injections are 
necessary to maintain optimal vision gains. Sustained release of ranibizumab from the 
Implant is an alternate dosing method that may result in a less frequent need of 
retreatment than dosing with ITV injections. This decrease in treatment burden could 
possibly reduce the risk of ITV injection-related AEs, increase compliance, and reduce 
the burden to patients, their caregivers, and the healthcare system, while maintaining 
optimum visual outcomes. 
4.2 
ANTICIPATED ADVERSE DEVICE EFFECTS 
The safety of the RPDS, as assessed using the following “Prespecified RPDS-associated 
AEs” include, but is not limited to an evaluation of: 
• 
Vitreous hemorrhage associated with a >30-letter decrease in best corrected visual 
acuity (BCVA) on the Early Treatment Diabetic Retinopathy Study (ETDRS) chart 
compared with the last assessment of BCVA prior to the onset of vitreous 
hemorrhage lasting >1 month 
• 
Reduced VA (>30-letter loss from previous scheduled visit) 
• 
Traumatic cataract 
• 
Endophthalmitis 
• 
Damage to sclera 
• 
Retinal detachment 
• 
Interference of the Implant with visual field 
 
Refer to protocol Section 6.5.1 and to the RPDS IB Section 6 for additional details. 
4.3 
RESIDUAL RISKS ASSOCIATED WITH THE INVESTIGATIONAL 
DEVICE, AS IDENTIFIED IN THE RISK ANALYSIS REPORT 
The details of the residual risks identified in the different risk analysis (e.g., failure mode 
and effects analysis) are described in the RPDS IB Section 6. 
4.4 
RISKS ASSOCIATED WITH PARTICIPATION IN THE CLINICAL 
INVESTIGATION 
The benefit and risks associated with participation in this study are outlined in the 
Informed Consent Form (ICF) and will be explained to the patient by the investigator. 
Ranibizumab has a well characterized safety profile, with clearly identified and potential 
risks associated with its use, which is described in the RPDS IB. The safety and 
tolerability of ranibizumab exposure delivered through the Implant were investigated in a 
Phase I prospective, open-label study in a wet AMD patient population by FSV4 at a 
single site in Latvia. The surgical procedure associated with Implant insertion could 

Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
Ranibizumab Port Delivery System—Genentech, Inc. 
215/Protocol GX28228, Version 8 
 
potentially lead to ocular AEs. These include, but are not limited to: ocular tissues 
inflammation or infection, conjunctival erosion, damage to the sclera, endophthalmitis, 
hypotony, suprachoroidal hemorrhage, and retinal detachment. The RPDS IFU 
describes all of the procedures necessary for successful insertion, refilling, and 
explantation of the Implant. It is imperative that specific surgical procedures are adhered 
to in order to minimize the risk of ocular AEs related to the procedure. 
4.5 
POSSIBLE INTERACTIONS WITH CONCOMITANT MEDICAL 
TREATMENTS 
At the discretion of their physician, patients may continue to receive all medications and 
standard treatments administered for other conditions with certain exceptions as detailed 
in the protocol Section 4.5.2. 
4.6 
STEPS THAT WILL BE TAKEN TO CONTROL OR MITIGATE 
THE RISKS 
Patients not considered suited for receiving the RPDS in this clinical investigation are 
excluded as outlined under exclusion criteria (see the protocol Section 4.1.2). 
Study investigators will be qualified ophthalmologists, trained in the management of 
retinal diseases and ocular surgery, and will be certified by a Sponsor-selected vendor to 
perform initial Implant fill, insertion, refill, and explantation. The surgical procedures 
involved in the use of the RPDS are also detailed in the RPDS IFU document. 
Patients must adhere to the instructions for prohibited therapy (see Section 4.5) and dose 
interruptions/study treatment or study discontinuation criteria (protocol Table 6). 
Prior to Implant insertion or explantation, patients will be required to verify that they have 
self-administered their antimicrobial eye drops to the study eye 4 times within the 
previous 24 hours. As per investigator’s discretion, patients may also be required to 
have self-administered antimicrobial eye drops to the study eye 4 times within the 24 
hours prior to Implant refills. It is required that all patients self-administer their 
antimicrobial drops again 4 times daily for 7 days following Implant insertion or 
explantation, and 4 times daily for 3 days following refills. Please see the protocol 
section 5.1 for additional details. 
The insertion procedure and, if applicable, the explantation procedure must be performed 
in the surgery room while the refill procedure is permitted in the physician office setting. 
The results of risk/benefit assessment from the overall risk analysis are described in the 
RPDS IB Section 6.

4.7 
RISK-TO-BENEFIT RATIONALE 
The Phase I study provided preliminary evidence of a positive benefit−risk profile for the 
use of RPDS in patients with wet AMD and supports the evaluation of RPDS in a Phase II 
study. It is expected that in the Phase II study the drug efficacy of at least one Implant 
treatment arm will be similar to the control ITV monthly injection treatment arm. 
Further details are included in the protocol Section 1.4. 
5. 
OBJECTIVES AND HYPOTHESES OF THE CLINICAL 
INVESTIGATION 
The objectives of the Phase II study are described in the protocol section 2. This RPDS 
CIP provides an overview of the device objectives and focuses on the parameters used 
for the assessment of RPDS functionality and safety. 
5.1 
DEVICE OBJECTIVES 
• 
To evaluate the functionality of the Implant by assessing that there is no evidence of 
Implant clogging in more than 10% of patients in the Implant arms at Month 9 
• 
To explore the serum ranibizumab concentration data with a PK model in an attempt 
to infer the concentration−time pattern in the vitreous humor and, if possible, derive 
information on the rate of ranibizumab release from the Implant 
• 
To evaluate the safety of the RPDS, as measured by “Prespecified 
RPDS-associated AEs” (see protocol Section 6.5.1) 
 
5.2 
HYPOTHESES, IMPLANT FUNCTIONALITY TO BE ACCEPTED 
OR REJECTED BY STATISTICAL DATA FROM THE CLINICAL 
INVESTIGATION 
The hypothesis to be established is that the initial Implant clogging rate does not exceed 
10% of Implant arm patients at Month 9. In order to evaluate whether the Implant 
clogging rate exceeds 10% within the first 9 months, the proportion of clogged Implants 
will be estimated and the 90% confidence interval will be calculated. All clogging data 
from patients in the Implant arms will be pooled for this analysis. 
In the study, the Implant will be judged as “failed” if it is determined that the RCE is 
clogged and can no longer deliver the ranibizumab into the ocular space (see Table 6 
“Failure to Operate State 1” and description below). 

Appendix 21

217/Protocol GX28228, Version 8 
 
5.3 
CLAIMS AND INTENDED PERFORMANCE OF THE IMPLANT 
THAT ARE TO BE VERIFIED 
Intended performance of the Implant is demonstrated by successful operation of drug 
diffusing across the RCE in a manner consistent with Fick’s Law of Diffusion as 
demonstrated in bench and animal studies. Implant functionality is demonstrated best in 
bench studies since there is no direct detectability in humans of Implant functionality that 
can be shown. No ethical method exists for directly measuring the flow of drug into the 
vitreous. Additionally serum pharmacokinetics is seen as too variable a measurement. 
The clinical performance of the Implant will be demonstrated by measuring the rate of 
events related to the occurrence of Implant clogging. 
The Implant will be assessed for possible clogging if the Implant is explanted. The 
following assessments will be performed: 
• 
Serum pharmacokinetics of ranibizumab will be used to judge whether Implant 
clogging may have occurred.  Aqueous and vitreous humor PK samples will also be 
collected at explantation and may be used to further assess possible Implant 
clogging. For each individual patient, possible Implant clogging will be documented 
if at least one of the following conditions is met: 
– 
For 40-mg/mL or 100-mg/mL dose groups: At Implant insertion and prior to the 
first refill: serum ranibizumab concentrations are below the lower limit of 
quantification (BLQ) or below the baseline serum ranibizumab concentration 
value at all time-points prior to refills, that is, on Day 1 (within 60 min of 
insertion – only if possible to collect), Day 2, Day 7, Day 14, and all monthly 
time points after insertion and prior to the first refill or to the last study visit for 
the patient, if no refill occurs 
– 
For the 10-mg/mL dose group: At Implant insertion and prior to the first refill: 
serum ranibizumab concentrations are below the lower limit of quantification 
(BLQ) value at all time-points prior to refills, that is, on Day 1 (within 60 min of 
insertion – only if possible to collect), Day 2, Day 7, Day 14, and all monthly 
timepoints after insertion and prior to the first refill or to the last study visit for 
the patient, if no refill occurs 
OR 
– 
After the first refill: serum ranibizumab concentrations are BLQ or below the 
last pre-refill serum ranibizumab concentration value at all time-points post 
refills, that is, on Day 7, and all monthly time points prior to the next refill for 
two consecutive refills, or to the last study visit for the patient, if no further refill 
occurs

The Implants meeting PK criteria for possible clogging will then undergo further 
diagnostics if explanted to confirm whether treatment failure was due to clogging. The 
“implant complete clogging” failure statistics will be summarized across all patients based

RISKS AND ANTICIPATED ADVERSE DEVICE EFFECTS THAT 
ARE TO BE ASSESSED 
At the end of the study, the incidence of “Prespecified RPDS-associated AEs” will be 
compared between subjects receiving ranibizumab from the Implant and the control 
subjects receiving ranibizumab as ITV injections: 
• 
Vitreous hemorrhage associated with a > 30-letter decrease in BCVA on the ETDRS 
chart compared with the last assessment of BCVA prior to the onset of vitreous 
hemorrhage lasting >1 month 
• 
Reduced VA (>30-letter loss from previous scheduled visit) 
• 
Traumatic cataract 
• 
Endophthalmitis 
• 
Damage to sclera 
• 
Retinal detachment

DESIGN OF THE CLINICAL INVESTIGATION 
6.1 
GENERAL 
6.1.1 
Type of Clinical Investigation and Rationale 
Study GX28228 is a Phase II, multicenter, randomized, active treatment (monthly ITV 
injection)−controlled study to evaluate ranibizumab delivered through the Implant using 
three ranibizumab formulation arms (10 mg/mL, 40 mg/mL, and 100 mg/mL) compared 
with the control arm (0.5-mg monthly ITV injections of 10-mg/mL formulation) in patients 
with subfoveal neovascular (wet) AMD. 
For details of the rationale for the design, refer to the Phase II protocol Section 3.4. 

Appendix 21

Investigation Plan (cont.) 
Ranibizumab Port Delivery System—Genentech, Inc. 
219/Protocol GX28228, Version 8 
 
6.1.2 
Measures to Minimize or Avoid Bias 
Patients will be randomized through an interactive voice/Web response system to one of 
four treatment arms. 
Study patients and all study site personnel will be masked to the Implant treatment arms’ 
ranibizumab formulation assignment (10 mg/mL vs. 40 mg/mL vs. 100 mg/mL) until the 
study conclusion. 
The Sponsor’s personnel directly involved in the study conduct (except the Internal 
Monitoring Committee [IMC] members) will be masked to the Implant treatment arms’ 
ranibizumab formulation assignment (10 mg/mL vs. 40 mg/mL vs. 100 mg/mL) until the 
time of primary analyses. The IMC will closely monitor patient safety throughout the 
study (see protocol Section 3.1.4). The IMC roles and responsibilities will be outlined in 
the IMC charter. 
Clinical pharmacology and PK scientists may be unmasked early for the purposes of 
interpreting emerging safety and efficacy data; those unmasked staff will not be part of 
the study team or have any interactions with sites or investigators. 
In addition, the VA examiner will only conduct refraction and VA assessments and will be 
masked to patient study eye assignment and patient treatment assignment. The VA 
examiner will have no access to patient VA scores from previous visits but will be only 
aware of the patient’s refraction data from previous visits. The VA examiner may perform 
no other direct patient-care tasks. Patients will be asked not to discuss their study       
eye assignment (right versus left) with the VA examiner. 
Patients and study site personnel will not be masked with regard to patient assignment to 
the ITV arm or an Implant arm because of the difficulties of maintaining masking following 
the surgical procedure, the additional safety visits applicable only to the Implant arms, 
and Implant visualization upon ophthalmic examination. 
6.1.3 
Device Endpoints, with Rationale for Their Selection and 
Measurement 
The Implant endpoint is the Implant status at the end of trial, which will be reported as 
either clogged or not clogged. The rationale for selecting Implant clogging as an 
endpoint is described in Section 3 of this RPDS CIP.

7. 
STATISTICAL CONSIDERATIONS 
7.1 
STATISTICAL DESIGN, METHOD AND ANALYTICAL 
PROCEDURES 
One objective in the clinical study is to demonstrate that there is no evidence that the 
Implant clogging rate exceeds 10% of patients in the Implant arms at Month 9. 
Implant clogging data from all patients that receive the Implant will be pooled together for 
this analysis. If there are 22 or fewer clogged Implants, among 165 evaluable Implants, 
within 9 months since insertion, we can declare that there is no evidence for the initial 
Implant clogging rate exceeding 10%. This acceptance criterion will be adjusted based 
on the actual number of evaluable Implants at end of study. The proportion of Implants 

Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
Ranibizumab Port Delivery System—Genentech, Inc. 
224/Protocol GX28228, Version 8 
 
that clog within 9 months and its 90% confidence interval will be estimated based on the 
binomial distribution. 
In addition, the safety data from three Implant arms will be pooled and compared with 
monthly ITV injection arm. The summary statistics (frequency and percentage) will be 
provided by Implant arm and monthly ITV arm. The safety assessment will review the 
following: 
• 
AEs 
• 
SAEs 
• 
“Prespecified RPDS-associated AEs” (see protocol Section 6.5.1) 
 
7.2 
SAMPLE SIZE 
This study is exploratory in nature and designed to estimate the time to first refill (TTFR) 
for each of the RPDS treatment arms (10 mg/mL, 40 mg/mL, and 100 mg/mL) enrolling 
60 patients in each of the RPDS treatment arms.  The sample size of approximately 
220 randomized patients will be adequate to evaluate the primary objectiveof the study. 
Pharmacokinetic-Pharmacodynamic modeling and simulation was performed to inform 
key assumptions used in sample size calculation. Given the simulation results, the 
hazard ratio for comparing the 100-mg/mL arm to the 10-mg/mL arm was estimated to 
be 0.66 for TTFR.  Assuming this hazard ratio, a total of at least 125 events from all 
three Implant groups is expected at the primary analysis time (approximately 85 events 
in the 10-mg/mL group and a higher dose group).  With 85 events, this study will have 
approximately 80% power to detect a hazard ratio=0.66 between the two Implant arms 
using a log-rank test at a one-sided significance level of 15%.  No multiplicity adjustment 
is planned for this Phase II study. 
Forty patients in the ITV arm will be sufficient to compare each device arm versus the 
ITV arm in change in BCVA from baseline through Month 9 (assuming an estimated 
SD=10 letters, a two-sided 80% CI will extend approximately 2.62 letters from the 
observed mean). 
7.3 
THE LEVEL OF SIGNIFICANCE AND THE POWER OF THE 
DEVICE CLINICAL INVESTIGATION 
The significance level used for Implant clogging data analysis is 0.05 and a one-sided 
test will be performed. 80% statistical power was used in above sample size section. 

Appendix 21  
Ranibizumab Port Delivery System:  Device Clinical 
Investigation Plan (cont.) 
Ranibizumab Port Delivery System—Genentech, Inc. 
225/Protocol GX28228, Version 8 
 
7.4 
EXPECTED DROP-OUT RATES 
Less than 8% dropout rate is expected based on the previous clinical trials for 
ranibizumab. Thus, an 8% dropout rate is assumed in the above sample size section for 
Implant clogging data analysis. 
7.5 
PASS/FAIL CRITERIA TO BE APPLIED TO THE RESULTS OF 
THE DEVICE CLINICAL INVESTIGATION 
The RPDS clinical investigation will be considered to successfully demonstrate Implant 
functionality if the following objective is met: 
• 
Establish that there is no evidence that the initial Implant clogging rate within 9 
months exceed 10% 
 
The RPDS clinical investigation will be considered to successfully demonstrate RPDS 
safety if the following objective is met: 
• 
Demonstrate that the AE profile observed when ranibizumab is administered using 
the Implant is clinically acceptable as compared with ranibizumab dosed using 
conventional ITV injection. In other words, any complications associated with 
Implant insertion, refill, or explantation, or associated with the long term presence of 
the Implant within the posterior chamber of the eye, are manageable and are 
acceptable in an overall benefit-risk assessment versus ITV dosing. 
 
This will include a characterization of the “Prespecified RPDS-associated AEs”, that is, 
those ADEs that have been pre-specified as being most relevant for the risk assessment 
of the Implant and the procedures of insertion, refill, and explantation. 
For each AE (including “Prespecified RPDS-associated AEs”) observed during the clinical 
study, the CRF will collect a separate assessment of investigator causality for each 
“study intervention” element, that is, investigator causality for “study drug” (i.e., 
ranibizumab [for both Implant arms and ITV dosing arm]), investigator causality for 
“procedures” (for both Implant arms and ITV dosing arm), and investigator causality for 
each of the RPDS components (for Implant arms only – the Implant, the Initial Fill 
Needle, the Insertion Tool, the Refill Needle, and the Explant Tool). Investigators will be 
trained on the requirement to assess each AE for potential causal association to “drug”, 
“procedure” and each of the “RPDS” device components −so that they may 
determine whether there is a causal association with one, more than one, or none of the 
“Study intervention” elements. 
If these objectives are not met, further design changes will be mandated.

MEDICAL CARE PROVIDED FOR SUBJECTS AFTER THE 
CLINICAL INVESTIGATION HAS BEEN COMPLETED 
Currently, the Sponsor doesn’t plan to provide ranibizumab via RPDS or via ITV 
injections or to provide other study interventions to patients after the conclusion of the 
study or following early patient withdrawal. The Sponsor will evaluate the 
appropriateness of continuing to provide ranibizumab treatment to RPDS treatment arms 
patients after evaluating RPDS efficacy, safety, and PK data gathered in the study. The 
Sponsor may offer study patients entry to a separate RPDS Extension Study to continue 
to provide ranibizumab to RPDS treatment arms patients via Implant in an open-label 
manner. 
For additional information, please refer to the ICF.
