Synopsis 
Protocol Title: LUMINA: A Phase III, Multicenter, Sham-Controlled, Randomized, Double-
Masked Study Assessing the Efficacy and Safety of Intravitreal Injections of 440 μg DE-109 for 
the Treatment of Active, Non-Infectious Uveitis of the Posterior Segment of the Eye. 
Table 2: 
Study Objectives, Estimands, and Endpoints 
Study Objectives and Estimands 
Corresponding Study Endpoints 
Primary objective (efficacy vs. sham): The 
primary objective of this study is to evaluate the 
efficacy of intravitreal injection of 440 μg DE-
109 every 2 months as compared with sham for 
the treatment of active, non-infectious uveitis of 
the posterior segment of the eye. 
Primary estimand: Vitreous haze 0 (VH0) 
response rate in DE-109 440 µg group vs. Sham 
group at Month 5 in all study eyes that received 
at least one dose of the study treatment where all 
eyes that were rescued due to worsening of 
uveitis or discontinued from the study due to lack 
of efficacy or due to adverse event before Month 
5 will be treated as non-responders. For study 
eyes that were rescued for any other reasons or 
had missing data due to other reasons, imputation 
by the multiple imputation-based approach will 
be used.  
Treatment policy estimand: VH0 response rate 
in DE-109 440 µg group vs. Sham group at 
Month 5 in all study eyes that received at least 
one dose of the study treatment regardless of 
whether subjects have received rescue therapy or 
discontinued from the study due to lack of 
efficacy or due to adverse event. For study eyes 
that had missing data due to any reason, 
imputation by the multiple imputation-based 
approach will be used. 
Composite estimand: Mean composite score in 
DE-109 440 µg group vs. Sham group at Month 
3 and at Month 5 in all study eyes that received 
at least one dose of study treatment. Each study 
eye will be assigned one of the following scores: 
 
Score = 3 if a study eye achieved VH 
score of 0 at the specified visit without 
taking any rescue therapies that could 
affect VH score prior to the specified 
visit  
Primary efficacy endpoint:  
 
VH 0 responsea at Month 5 
Key secondary efficacy endpoints:  
 
Composite endpointb at Month 5 
 
VH 0 response at Month 3 
 
Composite endpoint at Month 3 
Note: Overall Type I error rate will be maintained 
at 0.05 (two-sided) across primary and key 
secondary efficacy endpoint treatment 
comparisons.  
Other secondary efficacy endpoints: 
 
VH 0 or 2-unit responsec at Month 5 
 
VH 0 or 2-unit response at Month 3 
 
VH 0 or 0.5+ responsed at Month 5 
 
VH 0 or 0.5+ response at Month 3 
 
Corticosteroid tapering successe with 
resolution at Month 5

Study Objectives and Estimands 
Corresponding Study Endpoints 
 
Score = 2 if a study eye had at least 
improved by 2 units in VH (compared to 
baseline) at the specified visit without 
taking any rescue therapies that could 
affect VH score prior to the specified 
visit   
 
Score = 1 if a study eye achieved VH 
score of 0.5+ at the specified visit 
without taking any rescue therapies that 
could affect VH score prior to the 
specified visit   
 
Score = -1 if a study eye got rescued due 
to worsening of uveitis or discontinued 
from the study due to lack of efficacy or 
due to adverse event prior to the 
specified visit  
Score = 0 if otherwise 
 
Secondary (long-term efficacy): A secondary 
objective of this study is to evaluate the long-
term efficacy (> 6 months and up to one year) of 
intravitreal injection of 440 μg DE-109 every 2 
months for the treatment of active, non-infectious 
uveitis of the posterior segment of the eye. 
Secondary efficacy endpoints assessing long-term 
efficacy will include the following:  
VH 0 response at each visit after Month 6 
VH 0 or 2-unit response at each visit after Month 6 
VH 0 or 0.5+ response at each visit after Month 6 
Additional secondary and exploratory endpoints 
assessing long-term efficacy will be specified in 
the Statistical Analysis Plan.  
Secondary (safety): A secondary objective of 
this study is to evaluate the safety of intravitreal 
injection of 440 μg DE-109 every 2 months for 
up to one year of dosing for the treatment of 
active, non-infectious uveitis of the posterior 
segment of the eye.  
Safety of DE-109 will be assessed by adverse 
events (AEs), slit-lamp biomicroscopy, indirect 
ophthalmoscopy, BCVA, optical coherence 
tomography (OCT), fundus photography (FP), 
fluorescein angiography (FA), intraocular pressure 
(IOP), laboratory tests (serum chemistry, 
hematology, and urinalysis), physical 
examinations, and vital signs.  
Note: Vitreous haze (VH) will be scored using the modified Standardized Uveitis Nomenclature (SUN) scale.  
a VH 0 response (resolution of inflammation) is defined as a VH score of 0 in the study eye at a specified follow up 
visit based on the modified SUN scale.  
b  Refer to composite score scales defined in the composite estimand in this table.  
c VH 0 or 2-unit response is defined as having a VH score of 0 or a decrease (improvement) of at least 2 units  
(i.e., 2+ to 0, 3+ to 1+, or 4+ to 2+) from baseline in the study eye in VH score at a specified follow up visit based 
on the modified SUN scale.   
d VH 0 or 0.5+ response (remission of inflammation) is defined as a VH score of 0 or 0.5+ in the study eye at a 
specified follow-up visit based on the modified SUN scale.  
e Corticosteroid tapering success with resolution is defined as achievement of a prednisone-equivalent oral dose of 
0 mg/day and a VH score of 0 in the study eye at a specified follow-up visit. This endpoint is assessed based on 
the Intent-to-Taper population (study eyes of subjects who received systemic [oral] corticosteroids at a stable 
prednisone-equivalent dose between ≥15 mg/day and ≤40 mg/day that has remained stable for at least 1 week

[7 days] prior to and including on Day 1). 
f BCVA 3-line response is defined as an increase (improvement) of at least 3 lines (15 ETDRS letters) from 
baseline in BCVA at a specified follow-up visit. This endpoint is assessed based on eyes with a baseline best-
corrected visual acuity (BCVA) ≤ 70 ETDRS letters (Snellen equivalent of 20/40 or worse). 
Overall Design: 
This is a Phase III study to assess the efficacy and safety of DE-109 440 µg every 2 months in 
subjects with active, non-infectious uveitis of the posterior segment of the eye (NIU-PS). The 
12-month study consists of a 6-month, randomized, double-masked, parallel design, sham-
controlled evaluation of DE-109 440 µg every 2 months followed by a 6-month, open-label 
period in which all subjects will receive DE-109 440 µg every 2 months.  
The study will begin with a 30 days screening period (Day -30 to Day -1) which will be followed 
by the 6-month double-masked treatment period. In the double-masked period, approximately 
200 eligible subjects will be randomized in a 2:2:1 ratio to three arms: 
1. Test arm: Intravitreal injection of DE-109 440 µg in the study eye(s) every 2 months 
(Day 1, Month 2, and Month 4) (approximately 80 subjects). 
2. Control arm: Sham procedure administered to the study eye(s) every 2 months (Day 1, 
Month 2, and Month 4) (approximately 80 subjects). The sham procedure mimics an 
intravitreal injection without penetrating the eye (the blunt end of an empty syringe is 
pressed against an anesthetized eye).  
3. Dummy arm: Intravitreal injection of DE-109 at an undisclosed, fixed dose (within the 
range of 44 µg to 880 µg) in the study eye(s) every 2 months (Day 1, Month 2, and 
Month 4) (approximately 40 subjects). This study arm (which has the same route of 
administration and frequency as the test arm) is included in the study to help ensure 
masking of treatment assignments. The dose used in this arm will be chosen from a range 
of DE-109 doses (44 µg to 880 µg) previously demonstrated to have an acceptable safety 
profile. The dose in this arm will not vary between participating sites or subjects 
randomized to this arm.  
The hypothesis of the double-masked period is that the test arm (DE-109 440 µg dose every 
2 months) will demonstrate superior efficacy versus the sham control arm. To preserve the 
masking of treatment assignments, there will be separate, unmasked and masked investigators 
(and designated staff) during the double-masked period. At visits at which investigational 
product (IP) is being administered, the unmasked investigator (and designated staff) will 
administer the IP (DE-109 intravitreal injection and sham procedure) and conduct the post-
administration assessments; the masked investigator (and designated staff) will conduct the 
assessments prior to IP administration.  
Open-label period: Subjects completing the Month 6 pre-dose evaluations (the final evaluations 
in the double-masked period) will begin the open-label period of the study, in which all subjects 
will receive intravitreal injection of DE-109 440 µg in the study eye(s) every 2 months for an 
additional 6 months of dosing (i.e., IP injections at Month 6, Month 8, and Month 10 with a final 
follow-up evaluation at Month 12). The same study eye(s) treated during the double-masked 
period will be treated during the open-label period. The open-label period of the study will allow 
evaluation of the long-term (> 6 months and up to one year) efficacy and safety of DE-109 
440 µg every 2 months in subjects with NIU-PS.

Study Population: 
For study eligibility, active uveitis is defined as having a vitreous haze (VH) score of at least 
1.5+ based on the modified SUN scale. If anterior segment inflammation is present, it must be 
less severe than the posterior component. Subjects receiving systemic (oral) corticosteroid 
therapy will be eligible to enroll in the study; these subjects will be required to have received a 
prednisone-equivalent dose between ≥15 mg/day and ≤40 mg/day that has remained stable for at 
least 1 week (7 days) prior to and including on the first day of dosing (Day 1). Similarly, subjects 
receiving topical corticosteroid eye drops (other than difluprednate ophthalmic emulsion), topical 
non-steroidal anti-inflammatory eye drops, or certain immunosuppressants will be eligible and 
will be required to have received a stable dose/frequency of the therapy for at least 1 week  
(7 days) prior to Day 1 (Inclusion criteria Section 5.1, #6 and #8; Exclusion criteria Section 5.2, 
#14). 
If both of an eligible subject’s eyes meet all eligibility criteria, both eyes can be randomized into 
the study (i.e., both eyes can be study eyes) and will be assigned to the same treatment arm. The 
investigator will determine whether to enroll both eyes into the study after eligibility has been 
confirmed. The study randomization will include stratification by number of eyes enrolled (one 
eye or two eyes) as well as baseline systemic (oral) corticosteroid use (yes/no) and region (US or 
non-US). There will be separate drug supplies, records, and assessments for each study eye. 
If a fellow eye (non-study eye of a subject in the study) has uveitis at baseline or develops active 
uveitis during the study, the investigator should treat the eye with standard of care local 
therapies; systemically administered therapies should not be used to treat the fellow eye unless 
deemed to be medically necessary. DE-109 may not be administered to a fellow eye.  
Study Assessments: 
Study assessments will include fundus photography (FP), slit-lamp biomicroscopy, indirect 
ophthalmoscopy, optical coherence tomography (OCT), intraocular pressure (IOP), best-
corrected visual acuity (BCVA), fluorescein angiography (FA), the National Eye Institute Visual 
Functioning Questionnaire - 25 (VFQ-25), assessment of adverse events, laboratory tests (serum 
chemistry, hematology, and urinalysis), physical examination, vital signs, and pregnancy testing 
(serum and urine pregnancy tests for women of childbearing potential).  
Tapering of Systemic (Oral) Corticosteroid Use: 
Starting on Day 1, subjects receiving systemic (oral) corticosteroids at a stable prednisone-
equivalent dose between ≥15 mg/day and ≤40 mg/day will taper over a  maximum of 8 weeks to 
a prednisolone-equivalent dose of 0 mg/day. Corticosteroid tapering success with resolution of 
VH will be assessed in these subjects. The study randomization will include stratification by 
baseline systemic (oral) corticosteroid use (yes/no) as well as the number of eyes enrolled (one 
eye or two eyes) and region (US or non-US).  
Protocol-Specified Rescue Therapy Criteria: 
Rescue therapy is defined as any treatment that would have a therapeutic effect on NIU-PS. 
Rescue therapy is prohibited during the study unless there is worsening of uveitis as 
demonstrated by one or more of the following three rescue criteria: 
 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 13 of 133 
1. Worsening of uveitis in the study eye as indicated by at least a 2-step increase in VH 
score (i.e., 0 to ≥ 2+, 0.5+ to ≥ 3+, 1+ to ≥ 3+, 1.5+ to ≥ 4+, or 2+ to ≥ 4+) as 
compared to the baseline (Day 1) VH score or the best achieved VH score post 
baseline. 
2. Severe deterioration of vision in the study eye due to worsening of uveitis that is 
indicated by at least doubling of the visual angle (BCVA loss of 3 or more lines 
[≥15 ETDRS letters]) as compared to baseline (Day 1) BCVA. 
3. New or worsening retinal or choroidal uveitic lesion(s) in the study eye determined 
by clinical examination, as compared to baseline. 
When deemed medically necessary, rescue therapy may be administered at the discretion of the 
investigator, even if none of the protocol-specified rescue criteria noted above are satisfied. The 
investigator should contact the medical monitor to discuss the rescue treatment plan prior to the 
administration of rescue therapy. If the investigator is unable to reach the medical monitor, 
rescue treatment should be administered per the investigator’s clinical judgment and the medical 
monitor should be notified as soon as possible to discuss future on-study treatment plans for the 
subject. 
Interim Analyses, Primary Analysis, and Analysis of Open-Label Period: 
An interim analysis is planned when the first 100 subjects complete their Month 5 Visit.  There 
are two goals for this interim analysis (1) to assess for futility; and (2) to re-assess the sample 
size. Sample size re-assessment will be performed with the “promising zone” approach as 
follows (Mehta et al., 2011). If the conditional power at the interim analysis is between 50% and 
80%, the suggested sample size increase may be up to 100 subjects (i.e., 50% of the original 
sample size). If, on the other hand, the conditional power is > 80% or < 50%, no change to the 
sample size will take place. If the conditional power is <30%, then the Data Monitoring 
Committee (DMC) would recommend stopping the trial due to futility.  The DMC could 
recommend stopping the trial due to safety concerns at any of the DMC meetings and the interim 
analysis. An independent statistical and programming team will be used to perform this interim 
analysis of unmasked data and the DMC will review the results and make recommendations 
based on the findings. The planned interim analysis will be specified in greater detail in the SAP 
and in the DMC charter. 
The primary analysis of this study is the analysis of the data from the 6-month, double-masked 
period. These data will be quality-checked, soft-locked, and the primary analysis will be 
conducted after all subjects have completed the Month 6 visit or prematurely discontinued from 
the study prior to Month 6. An interim clinical study report will be written documenting the 
primary analysis results.  
Analysis of the open-label period of the study will be performed after the end of the study and 
documented in the final clinical study report.  
Data Monitoring Committee: 
An independent Data Monitoring Committee (DMC) whose members will not be participating in 
the LUMINA study conduct will serve as an advisory board to the Santen senior management 
team. The DMC will periodically review and make recommendations based on interim data; 
unmasked data will only be reviewed in closed DMC sessions without participation of Santen

INTRODUCTION 
DE-109 is a formulation of sirolimus administered by intravitreal injection that is being 
developed for the treatment of non-infectious uveitis of the posterior segment of the eye 
(intermediate, posterior, and panuveitis). Sirolimus is an inhibitor of the mammalian target of 
rapamycin (mTOR) and acts as an immunoregulator.  
2.1. 
Study Rationale 
Phase III study 010906IN (LUMINA) will evaluate the efficacy and safety of intravitreal 
injection of DE-109 440 µg administered every 2 months for the treatment of active, 
non-infectious uveitis of the posterior segment of the eye (NIU-PS). In two Phase III studies 
conducted previously in this indication, three doses of DE-109 were evaluated (44 µg, 440 µg, 
and 880 µg, each administered every 2 months); the 440 µg dose demonstrated the optimal 
benefit-risk profile. The 6-month, double-masked period of Phase III study LUMINA is being 
conducted to confirm the efficacy and safety of DE-109 440 µg administered every 2 months 
when compared to a sham control. The 6-month, open-label period of the study will allow 
evaluation of the long-term (> 6 months and up to one year) efficacy and safety of DE-109 
440 µg every 2 months in subjects with NIU-PS. 
2.2. 
Background 
Non-infectious uveitis of the posterior segment of the eye (NIU-PS) is a heterogeneous group of 
intraocular inflammation disorders with both exogenous (infection, trauma) and endogenous 
(autoimmune, idiopathic) etiologies that affects up to 730 people per 100,000 (Durrani et al., 
2004; Jabs et al., 2005). In chronic uveitis, cumulative structural damage and loss of vision result 
from recurrent episodes of inflammation. Thus, active uveitis requires urgent treatment to control 
inflammation.  
Historically, the primary treatment for NIU-PS has been systemic corticosteroid therapy. More 
recently, ocular implants that deliver corticosteroid locally have become available. Systemic 
corticosteroid therapy is associated with known comorbidities (e.g., osteoporosis, hypertension, 
and diabetes, as well as cataracts and glaucoma) that may escalate with dose and frequency of 
use. The available corticosteroid ocular implants are associated with a high rate of increased 
intraocular pressure (IOP), the attendant risk of glaucoma, and with increased risk of cataract 
development. Other systemic immunosuppressive therapies (antimetabolites, T-cell inhibitors, 
alkylating agents, and biologics) may be appropriate as monotherapy in certain patients, or these 
agents may be used to lower the corticosteroid dose, however close monitoring is required due to 
potentially serious side effects such as hepatotoxicity, myelosuppression, or malignancy. Given 
the treatment-limiting side effects of current therapies, there remains an unmet medical need in 
NIU-PS for therapies that can be used on a long-term basis to address the chronicity of the 
disease.  
Sirolimus (also known as rapamycin) is a macrolide antibiotic that inhibits the mammalian target 
of rapamycin (mTOR), a multifunctional kinase. Inhibition of mTOR and its downstream 
signaling molecules by sirolimus results in immunosuppression, primarily by interrupting the 
inflammatory cascade that leads to T-cell activation and proliferation. Emerging evidence 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 19 of 133 
suggests that sirolimus also promotes immune tolerance by inducing regulatory T-cells (Tregs), 
which may contribute to the treatment of non-infectious uveitis because of the potential 
dysfunction of Tregs in autoimmune diseases. Sirolimus received initial US regulatory approval 
in 1999 (as Rapamune®) for the prophylaxis of organ rejection in renal transplant patients; 
sirolimus is also the active ingredient in a drug-eluting stent (the CYPHER® Sirolimus-eluting 
Coronary Stent) marketed for improving coronary luminal diameter in patients with symptomatic 
ischemic disease. Evidence of the efficacy of sirolimus in treating uveitis was first obtained in an 
investigator-sponsored study, the SAVE study (Ibrahim et al., 2015; Nguyen et al., 2013). In this 
study of 30 subjects with non-infectious uveitis, sirolimus administered by either intravitreal or 
subconjunctival injection was generally well tolerated and showed bioactivity in reducing 
vitreous haze and cells, in improving visual acuity, and in decreasing the need for systemic 
corticosteroids.  
DE-109 is a formulation of sirolimus that forms a depot which localizes in the inferior portion of 
the vitreous humor, providing sirolimus exposure to the retina/choroid for approximately two 
months. Santen has conducted a nonclinical and clinical development program of DE-109 
through Phase III to demonstrate the efficacy and safety of DE-109 in the treatment of NIU-PS. 
A detailed description of the chemistry, pharmacology, efficacy, and safety of DE-109 is 
provided in the DE-109 Investigational Brochure.  
2.3. 
Benefit/Risk Assessment 
Two Phase III studies have been completed (SAKURA Program: SAKURA Study 1 and 
SAKURA Study 2) which evaluated three doses of DE-109 (44 μg, 440 μg, and 880 μg, each 
administered every 2 months) in subjects with active NIU-PS. A total of 590 randomized, treated 
study eyes (590 subject IDs, 589 subjects) received at least one injection of DE-109 (i.e., 
integrated Safety population).  In the integrated Safety population of the two studies, 459 treated 
study eyes were exposed to the 440 or 880 μg dose of DE-109 for at least 6 months (defined as 
staying in study under either dose for at least 173 days after the first 440 or 880 μg dose) and 318 
treated study eyes were exposed to the 440 or 880 μg dose for at least 1 year (defined as staying 
in study for at least 346 days after the first 440 or 880 μg dose). The DE-109 440 μg dose 
exhibited the optimal benefit/risk profile in Study 1 and performed similarly in Study 2. The 
efficacy and safety data in these large Phase III studies support the 440 μg dose as the most 
appropriate dose of DE-109 for treating active NIU-PS. For the primary endpoint (VH score of 0 
at Month 5), the response rate in the 440 μg dose group was appreciable and consistent across the 
two studies (22.8% and 19.1% in Study 1 and Study 2, respectively).  
The safety data from the SAKURA program demonstrated a reasonable safety profile of the 
440 µg dose of DE-109, with few risks directly related to its use. Risks associated with the use of 
DE-109 are non-infectious endophthalmitis, which was observed mostly with the 880 µg dose 
and successfully treated with corticosteroids and surgical intervention, and the presence of drug 
depot in the visual axis, which, if it occurs, is a self-limiting event that may resolve as the drug 
depot dissolves and moves out of the visual axis. At all three doses (44 μg, 440 μg, and 880 μg, 
each administered every 2 months), DE-109 had minimal effect on IOP with repeat dosing and 
the systemic exposures after intravitreal dosing were well below the levels required for 
immunosuppression, thereby minimizing the possibility of systemic side effects.

The undisclosed, fixed dose of DE-109 in the Dummy arm will be within the range of doses 
evaluated in the previous Phase III studies (44 μg to 880 μg), all of which have demonstrated an 
acceptable safety profile.  
The control arm for the 6-month, double-masked period of this study is a sham procedure, which 
mimics an intravitreal injection without penetrating the eye. The protocol allows for the 
administration of rescue therapy for any subject in the study who experiences a worsening of 
uveitis.  
Refer to the DE-109 Investigational Brochure for detailed descriptions of completed studies of 
DE-109 and the safety and efficacy data relevant to the clinical use of DE-109 in NIU-PS.

of this study is to evaluate the safety of 
intravitreal injection of 440 μg DE-109 every 
2 months for up to one year of dosing for the 
treatment of active, non-infectious uveitis of 
the posterior segment of the eye.  
Safety of DE-109 will be assessed by adverse events 
(AEs), slit-lamp biomicroscopy, indirect 
ophthalmoscopy, BCVA, optical coherence 
tomography (OCT), fundus photography (FP), 
fluorescein angiography (FA), intraocular pressure 
(IOP), laboratory tests (serum chemistry, hematology, 
and urinalysis), physical examinations, and vital signs.  
Note: Vitreous haze (VH) will be scored using the modified Standardized Uveitis Nomenclature (SUN) scale.  
a VH 0 response (resolution of inflammation) is defined as a VH score of 0 in the study eye at a specified follow up 
visit based on the modified SUN scale. 
b  Refer to composite score scales defined in the composite estimand in this table.  
c VH 0 or 2-unit response is defined as having a VH score of 0 or a decrease (improvement) of at least 2 units  
(i.e., 2+ to 0, 3+ to 1+, or 4+ to 2+) from baseline in the study eye in VH score at a specified follow up visit based 
on the modified SUN scale.   
d VH 0 or 0.5+ response (remission of inflammation) is defined as a VH score of 0 or 0.5+ in the study eye at a 
specified follow-up visit based on the modified SUN scale.  
e Corticosteroid tapering success with resolution is defined as achievement of a prednisone-equivalent oral dose of 
0 mg/day and a VH score of 0 in the study eye at a specified follow-up visit. This endpoint is assessed based on 
the Intent-to-Taper population (study eyes of subjects who received systemic [oral] corticosteroids at a stable 
prednisone-equivalent dose between ≥15 mg/day and ≤40 mg/day that has remained stable for at least 1 week  
[7 days] prior to and including on Day 1). 
f BCVA 3-line response is defined as an increase (improvement) of at least 3 lines (15 ETDRS letters) from 
baseline in BCVA at a specified follow-up visit. This endpoint is assessed based on eyes with a baseline best-
corrected visual acuity (BCVA) ≤ 70 ETDRS letters (Snellen equivalent of 20/40 or worse).

STUDY DESIGN 
4.1. 
Overall Design 
This is a Phase III study to assess the efficacy and safety of DE-109 440 µg every 2 months in 
subjects with active, non-infectious uveitis of the posterior segment of the eye (NIU-PS). The 
12-month study consists of a 6-month, randomized, double-masked, parallel design, sham-
controlled evaluation of DE-109 440 µg every 2 months followed by a 6-month, open-label 
period in which all subjects will receive DE-109 440 µg every 2 months.  
The study will begin with a 30 days screening period (Day -30 to Day -1) which will be followed 
by the 6-month, double-masked treatment period. In the double-masked period, approximately 
200 eligible subjects will be randomized in a 2:2:1 ratio to three arms: 
1. Test arm: Intravitreal injection of DE-109 440 µg in the study eye(s) every 2 months 
(Day 1, Month 2, and Month 4) (approximately 80 subjects). 
2. Control arm: Sham procedure administered to the study eye(s) every 2 months (Day 1, 
Month 2, and Month 4) (approximately 80 subjects). The sham procedure mimics an 
intravitreal injection without penetrating the eye (the blunt end of an empty syringe is 
pressed against an anesthetized eye).  
3. Dummy arm: Intravitreal injection of DE-109 at an undisclosed, fixed dose (within the 
range of 44 µg to 880 µg) in the study eye(s) every 2 months (Day 1, Month 2, and 
Month 4) (approximately 40 subjects). This study arm (which has the same route of 
administration and frequency as the test arm) is included in the study to help ensure 
masking of treatment assignments. The dose used in this arm will be chosen from a range 
of DE-109 doses (44 µg to 880 µg) previously demonstrated to have an acceptable safety 
profile. The dose in this arm will not vary between participating sites or subjects 
randomized to this arm. 
The study objectives and endpoints are provided in Section 3.  The hypothesis of the double-
masked period is that the test arm (DE-109 440 µg dose every 2 months) will demonstrate 
superior efficacy versus the sham control arm. To preserve the masking of treatment 
assignments, there will be separate, unmasked and masked investigators (and designated staff) 
during the double-masked period. At visits at which IP is being administered, the unmasked 
investigator (and designated staff) will administer the IP (DE-109 intravitreal injection and sham 
procedure) and conduct the post-administration assessments; the masked investigator (and 
designated staff) will conduct the assessments prior to IP administration.  
Open-label period: Subjects completing the Month 6 pre-dose evaluations (the final evaluations 
of the double-masked period) will begin the open-label period of the study in which all subjects 
will receive intravitreal injection of DE-109 440 µg in the study eye(s) every 2 months for an 
additional 6 months of dosing (i.e., IP injections at Month 6, Month 8, and Month 10 with a final 
follow-up evaluation at Month 12). The same study eye(s) treated during the double-masked 
period will be treated during the open-label period. The open-label period of the study will allow 
evaluation of the long-term (> 6 months and up to one year) efficacy and safety of DE-109 
440 µg every 2 months in subjects with NIU-PS.

Study Population: 
For study eligibility, active uveitis is defined as having a vitreous haze (VH) score of at least 
1.5+ based on the modified SUN scale. If anterior segment inflammation is present, it must be 
less severe than the posterior component. Subjects receiving systemic (oral) corticosteroid 
therapy will be eligible to enroll in the study; these subjects will be required to have received a 
stable prednisone-equivalent dose between ≥15 mg/day and ≤40 mg/day that has remained stable 
for at least 1week (7 days) prior to and including on Day 1. Similarly, subjects receiving topical 
corticosteroid eye drops (other than difluprednate ophthalmic emulsion), topical non-steroidal 
anti-inflammatory eye drops, or certain immunosuppressants will be eligible and will be required 
to have received a stable dose/frequency of the therapy for a specified duration prior to Day 1 
(inclusion criteria Section 5.1, #6 and #8; exclusion criteria Section 5.2, #14). 
If both of an eligible subject’s eyes meet all eligibility criteria, both eyes can be randomized into 
the study (i.e., both eyes can be study eyes) and will be assigned to the same treatment arm. The 
investigator will determine whether both eyes are eligible for randomization into the study. 
Additional guidance regarding the enrollment of both or one of two eligible eyes is provided in 
Section 5. The study randomization will include stratification by number of eyes enrolled (one 
eye or two eyes) as well as baseline systemic (oral) corticorsteroid use (yes/no) and region (US 
or non-US). There will be separate drug supplies, records, and assessments for each study eye. 
If a fellow eye (non-study eye of a subject in the study) has uveitis at baseline or develops active 
uveitis during the study, the investigator should treat the eye with standard of care local 
therapies; systemically administered therapies should not be used to treat the fellow eye unless 
deemed to be medically necessary. DE-109 may not be administered to a fellow eye.  
Overview of Study Assessments: 
Study assessments will include fundus photography (FP), slit-lamp biomicroscopy, indirect 
ophthalmoscopy, optical coherence tomography (OCT), intraocular pressure (IOP), best-
corrected visual acuity (BCVA), fluorescein angiography (FA), the National Eye Institute Visual 
Functioning Questionnaire - 25 (VFQ-25), assessment of adverse events, laboratory tests (serum 
chemistry, hematology, and urinalysis), physical examination, vital signs, and pregnancy testing 
(serum and urine pregnancy tests for women of childbearing potential).  
Tapering of Systemic (Oral) Corticosteroid:  
Starting on Day 1, subjects receiving systemic (oral) corticosteroids at a stable prednisolone-
equivalent dose between ≥15 mg/day and ≤40 mg/day will taper over a maximum of 8 weeks to 
a prednisolone-equivalent dose of 0 mg/day according to the tapering regimen described in 
Section 6.5.3 (the dose of corticosteroid must remain stable for 1 week [7 days] prior to and 
including on Day 1). Corticosteroid tapering success with resolution of VH will be assessed in 
these subjects. The study randomization will include stratification by baseline systemic (oral) 
corticosteroid use (yes/no) as well as the number of eyes enrolled (one eye or two eyes) and 
region (US or non-US).

Protocol-Specified Rescue Therapy Criteria: 
Rescue therapy is defined as any treatment that would have a therapeutic effect on NIU-PS 
(detailed definition in Section 6.5.6). Rescue therapy is prohibited during the study unless there 
is worsening of uveitis as demonstrated by one or more of the following three rescue criteria:  
1. Worsening of uveitis in the study eye as indicated by at least a 2-step increase in VH 
score (i.e., 0 to ≥ 2+, 0.5+ to ≥ 3+, 1+ to ≥ 3+, 1.5+ to ≥ 4+, or 2+ to ≥ 4+)  as compared 
to the baseline (Day 1) VH score or best achieved VH score post baseline. 
2. Severe deterioration of vision in the study eye due to worsening of uveitis that is 
indicated by at least doubling of the visual angle (BCVA loss of 3 or more lines 
[≥15 ETDRS letters]) as compared to baseline (Day 1) BCVA. 
3. New or worsening retinal or choroidal uveitic lesion(s) in the study eye determined by 
clinical examination, as compared to baseline. 
When deemed medically necessary, rescue therapy may be administered at the discretion of the 
investigator, even if none of the protocol-specified rescue criteria noted above are satisfied. The 
investigator should contact the medical monitor to discuss the rescue treatment plan prior to the 
administration of rescue therapy. If the investigator is unable to reach the medical monitor, 
rescue treatment should be administered per the investigator’s clinical judgment and the medical 
monitor should be notified as soon as possible to discuss future on-study treatment plans for the 
subject. 
Interim Analyses, Primary Analysis, and Analysis of Open-Label Period: 
An interim analysis is planned when the first 100 subjects complete their Month 5 Visit.  There 
are two goals for this interim analysis (1) to assess for futility; and (2) to re-assess the sample 
size. Sample size re-assessment will be performed with the “promising zone” approach as 
follows (Mehta et al., 2011). If the conditional power at the interim analysis is between 50% and 
80%, the suggested sample size increase may be up to 100 subjects (i.e., 50% of the original 
sample size). If, on the other hand, the conditional power is > 80% or < 50%, no change to the 
sample size will take place. If the conditional power is <30%, then the Data Monitoring 
Committee (DMC) would recommend stopping the trial due to futility.  The DMC could 
recommend stopping the trial due to safety concerns at any of the DMC meetings and the interim 
analysis. An independent statistical and programming team will be used to perform this interim 
analysis of unmasked data and the DMC will review the results and make recommendations 
based on the findings. The planned interim analysis will be specified in greater detail in the SAP 
and in the DMC charter. 
The primary analysis of this study is the analysis of the data from the 6-month, double-masked 
period. These data will be quality-checked, soft-locked, and the primary analysis will be 
conducted after all subjects have completed the Month 6 visit or prematurely discontinued from 
the study prior to Month 6. An interim clinical study report will be written documenting the 
primary analysis results.  
Analysis of the open-label period of the study will be performed after the end of the study and 
documented in the final clinical study report.

Data Monitoring Committee: 
An independent data monitoring committee (DMC) whose members will not be participating in 
the LUMINA study conduct will serve as an advisory board to the Santen senior management 
team. The DMC will periodically review and make recommendations based on interim data; 
unmasked data will only be reviewed in closed DMC sessions without participation of Santen 
personnel. The organization, responsibilities, and procedures of the DMC will be specified in a 
governing charter.  
4.2. 
Scientific Rationale for Study Design 
The double-masked, randomized, parallel design of the 6-month, comparative period of this 
study is a recognized standard in the evaluation of experimental drug therapies. A subsequent 
single-arm, open-label period, as used in this study, is also a frequently chosen strategy to allow 
evaluation of longer-term efficacy and safety of an experimental drug regimen without requiring 
long-term treatment with a placebo/sham control.  
Given the potential risks associated with intravitreal injections, a sham administration procedure 
is used as a control during the study’s double-masked period rather than an intravitreal injection 
of placebo medication. Sham administration has been routinely used as a control arm in Phase III 
studies of other intravitreally administered therapies for ocular diseases, including uveitis. To 
preserve the masking of the investigator conducting the study assessments, a separate, unmasked 
investigator (and designated staff) will administer the IP (intravitreal injection of DE-109 or 
sham procedure) during the double-masked period. Inclusion of an additional arm (the dummy 
arm), in which subjects receive intravitreal injections of DE-109 at a single, undisclosed fixed 
dose every 2 months, will help to ensure masking in this sham-controlled study. The dose in this 
arm will not vary between participating sites or subjects randomized to this arm. 
Vitreous haze has been previously used as a primary efficacy endpoint in the clinical 
development of other medicinal products for uveitis. Vitreous haze (VH) is a descriptive term for 
the obscuration of fundus details by vitreous cells and protein exudation and was selected as the 
primary efficacy measure because it is strongly linked to inflammation. An assessment of the 
amount of haze is used as a surrogate marker for the degree of inflammation. A six-step scale of 
VH was created at the National Eye Institute in 1985 (Nussenblatt et al., 1985). This scale was 
approved by the Standardization of Uveitis Nomenclature (SUN) Working Group in 2005 as an 
acceptable method of grading VH in clinical research (Sun Working, 2005). 
The primary efficacy endpoint is defined as a VH score of 0 (resolution of inflammation) at 
Month 5; a VH score of 0 at Month 3, composite score at Month 3 and at Month 5 are key 
secondary efficacy endpoints. Month 5 (one month after the Month 4 injection) and Month 3 
(one month after the Month 2 injection) were selected as pre-specified endpoints for evaluating 
VH based on tissue distribution studies which demonstrated that peak levels of sirolimus are 
maintained at the target tissue for up to two months after intravitreal injection of DE-109.  
Secondary efficacy assessments include benefit as measured by the ability to taper from 
corticosteroids and achieve resolution of VH, which is evaluated in the subgroup of subjects 
receiving systemic (oral) corticosteroids at baseline. Accordingly, to help ensure balance across 
the treatment arms within this subgroup, the study randomization will be stratified by subject’s 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution

systemic (oral) corticosteroid use at baseline (yes/no) as well as the number of eyes enrolled (one 
eye or two eyes) and region (US or non-US).  
In this study which includes a sham control during the double-masked period, rescue therapy is 
allowed for subjects who experience worsening of disease or vision per protocol-specified 
criteria, or at the investigator’s judgement. In the analysis of VH endpoints including the primary 
endpoint, the use of rescue therapy prior to the evaluation of a VH endpoint will be accounted for 
by considering the subject to be a non-responder.  
An independent Data Monitoring Committee (DMC) will periodically review unmasked 
aggregated and individual-level data during the conduct of the trial to help ensure safety and data 
integrity. An independent statistical and programming team will be used to perform these interim 
analyses of unmasked data.  
Use of the 6-month, single-arm, open-label period after completion of the 6-month double-
masked, controlled period allows the evaluation of the efficacy and safety of intravitreal injection 
of DE-109 440 µg every 2 months for longer duration than appropriate for a placebo or sham 
control.  
4.3. 
Justification for Dose 
The first evidence of the favorable benefit-risk profile of intravitreal injection of sirolimus in 
treating non-infectious uveitis was provided by the SAVE study (Ibrahim et al., 2015; Nguyen et 
al., 2013). In SAVE, 30 subjects with active or quiescent non-infectious uveitis were randomized 
to receive intravitreal or subconjunctival injections of sirolimus every 60 days through day 120 
and at dosing intervals ≥ 2 months from month 6 up to month 12. The SAVE study indicated that 
local administration of sirolimus, including an intravitreal dose of 352 µg every 60 days, was 
generally well tolerated and showed bioactivity in reducing vitreous haze, in improving visual 
acuity, and in decreasing the need for systemic corticosteroids.  
In the two Phase III clinical trials conducted previously by Santen (SAKURA 1 and SAKURA 
2), the efficacy and safety of three doses of DE-109 (44 μg, 440 μg, and 880 μg) administered 
every 2 months were evaluated for the treatment of NIU-PS. The primary efficacy endpoint 
evaluation was at Month 5. A total of 590 randomized, treated study eyes (590 subject IDs, 
589 subjects) received at least one injection of DE-109. The 440 μg dose of DE-109 
(administered to a total of 208 study eyes) demonstrated the optimal benefit-risk profile. The  
6-month, double-masked period of Phase III study LUMINA is being conducted to confirm the 
efficacy and safety of DE-109 440 µg administered every 2 months when compared to a sham 
control.  
4.4. 
End of Study Definition 
A subject is considered to have completed the study if he/she has completed all periods of the 
study including the last visit or the last scheduled procedure shown in the Schedule of Activities 
(Section 1.3). The end of the study is defined as the date of the last visit of the last subject in the 
study.

STUDY POPULATION 
The study will be conducted at up to approximately 100 investigative sites globally.  
The study inclusion and exclusion criteria are specified below. Prospective approval of protocol 
deviations to recruitment and enrollment criteria, also known as protocol waivers or exemptions, 
will not be permitted.  
Guidance regarding enrollment of both eyes:  
If both of an eligible subject’s eyes meet all eligibility criteria, both eyes can be randomized into 
the study (i.e., both eyes can be study eyes). The investigator will determine whether to enroll 
both eyes into the study after eligibility has been confirmed.  
 Both eyes eligible, enrolling both of the subject’s eyes:   
 Both eyes should be enrolled on a single Day 1 (Baseline) visit.  
 The IWRS will assign both eyes to the same treatment arm.  
 There will be separate drug supplies, records, and assessments for each study eye.  
 Both eyes eligible, enrolling only one of the subject’s two eligible eyes:   
 The eye with the higher Day 1 (Baseline) VH score should be enrolled.  
 If the VH scores are the same, the right eye should be enrolled.

to Day 1, or planning to participate in other investigational drug or device clinical trials 
during a time which would overlap with the duration of the study. This includes both 
ocular and non-ocular clinical trials. Exposure to investigational biologics should be 
discussed with medical monitor. 
In addition, the investigator or Santen medical monitor may declare a subject ineligible for any 
sound reason.  
5.3. 
Lifestyle Considerations 
5.3.1. 
Contraception Requirements 
There are no controlled data with the IP in human pregnancy. It is required that females of 
childbearing potential and male subjects able to father children abstain from intercourse or agree 
to practice acceptable methods of contraception throughout the course of the study (i.e., 
intrauterine device, oral contraceptives, barrier method, or other contraception deemed adequate 
by the investigator).  
5.3.2. 
Fasting Prior to Blood Draws for Hematology and Chemistry Laboratory Tests 
Requirements for fasting 8 hours prior to the blood draw for hematology and chemistry 
laboratory tests taken at visits is specified in the SoA (Table 3). 
5.4. 
Screen Failures and Rescreening 
Screen failures are defined as subjects who consent to participate in the clinical study but are not 
subsequently randomly assigned to IP. The following screen failure information is required to 
ensure transparent reporting of screen failure subjects, to meet the Consolidated Standards of 
Reporting Trials (CONSORT) publishing requirements, and to respond to queries from 
regulatory authorities: demography, screen failure details, eligibility criteria, and any SAEs 
reported during screening. The final study report will include screen failure information in 
support of these requirements.  
In this study, a subject who fails screening may be considered for rescreening in consultation 
with the Sponsor or its designee and providing that the subject undergoes re-consent. In no case 
will a subject be allowed to be rescreened more than once. If a subject is to be rescreened after 
failing screening, a new screening period will begin, and all study eligibility criteria will need to 
be re-assessed and confirmed prior to randomization into the study. Rescreened subjects will be 
assigned a new subject number.

STUDY INTERVENTION 
Study intervention is a general term that refers to any investigational intervention(s), marketed 
product(s), placebo, sham, or medical device(s) intended to be administered to a study subject 
according to a study protocol. In this protocol, the term Investigational Product (IP) is generally 
used to refer to the study interventions, which are the following three DE-109/sham regimens, 
one of which is randomly assigned to each subject’s study eye(s) during the double-masked 
period: (1) DE-109 440 µg administered by intravitreal injection every 2 months, (2) sham 
procedure administered every 2 months, and (3) dummy (DE-109 at an undisclosed fixed dose of 
44 µg to 880 µg) administered by intravitreal injection every 2 months (at the Day 1, Month 2, 
and Month 4 visits). During the open-label period, the IP received will be the same for all 
subjects: DE-109 440 µg administered by intravitreal injection every 2 months (at the Month 6, 
Month 8, and Month 10 visits).

Investigational Product Storage, Preparation, Administration, 
Accountability, Handling, and Disposal 
Refer to the Investigational Product Manual for detailed instructions regarding receipt, handling, 
management, storage, administration, and return/disposal of IP, as well as information regarding 
other clinical supplies provided by Santen.  
6.2.1. 
Investigational Product Storage 
Investigational product will be received frozen and should remain frozen in a secure, locked, 
dark, temperature-controlled freezer at -20°C ± 5°C (with allowable temperature excursions up 
to -35°C). Investigational product must be stored with access limited to the authorized site staff 
until the time of use.  
6.2.2. 
Investigational Product Preparation 
On study visits during the double-masked period at which IP is administered (see SoA, Table 3), 
the unmasked investigator or designee will perform the IP preparation and administration. 
IP Preparation for Test Arm (DE-109 440 µg) and Dummy Arm (DE-109 at an undisclosed, 
fixed dose of 44 µg to 880 µg):  
The vial of IP (unique vial number is assigned to a subject’s specific study eye by IWRS) will be 
removed from the freezer and thawed by rotating the vial between the palms of the hands for a 
minimum of approximately 5 minutes, or by setting the vial at room temperature for a minimum 
of approximately 30 minutes. Care should be taken to protect the product from light. After the 
product is thawed, mix the product by gently inverting the vial a few times. Investigational 
product should be drawn into the provided single-use plastic syringe within 60 minutes after 
removing the vial from the freezer. Investigational product should be injected within 2 hours of 
being drawn up into the single-use syringe. 
DE-109 drug product is dispensed from a 2 mL vial. Each vial contains enough IP to inject one 
study eye. Each vial will be used one time only.  
A sterile, single-use 250 μL syringe custom marked at 20 µL as well as two needles (21G and 
30G) will be provided as a kit. Each dose of DE-109 should be administered within 2 hours of 
being drawn up into the single-use plastic syringe. Instructions for filling the syringe are as 
follows: 
1. Remove the sterile, single-use 250 μL syringe custom marked at 20 µL from the 
packaging. 
a. Attach a 21-gauge x 1 ½  inch needle to the syringe.

2. Using sterile technique, carefully draw up more than 20 µL of DE-109 into the plastic 
syringe.  It should be noted that due to the slight viscosity, drawing up DE-109 will be 
slow.   
3. Replace the needle with a 30-gauge x 0.5 inch needle in preparation for the DE-109 
intravitreal injection.   
a. Ensure that the 30-gauge by 0.5 inch needle is affixed tightly to the syringe.   
b. ALIGN THE TOP EDGE OF THE RED O RING OF THE PLUNGER WITH 
THE 20 µL BLACK MARK ON THE SYRINGE (See Figure 3). 
c. PLEASE ENSURE THAT THERE ARE NO AIR BUBBLES WITHIN THE 
SYRINGE OR THE NEEDLE HUB PRIOR TO INJECTION.   
Figure 3: 
 
IP Preparation for Control Arm (Sham):  
Removal and thawing procedures are the same for Sham as for DE-109. A syringe loading 
procedure similar to DE-109 should be performed; no drug product will be drawn up into the 
syringe.  
6.2.3. 
Investigational Product Administration 
During the double-masked period, the unmasked investigator will perform all IP administrations 
(DE-109 440 µg, Sham, and Dummy [an undisclosed, fixed dose of DE-109 in the range of  
44 µg to 880 µg]).  
The procedures for IP administration to a single study eye are shown in Table 6. Note that the 
subjects’ pupils will already have been dilated by the masked investigator/staff prior to the 
conduct of the pre IP administration assessments. Detailed guidance regarding IP administration, 
including administration to both eyes, is provided in the Investigational Product Manual.

discretion. 
4. Take 2 sterile cotton tipped applicators and 
thoroughly soak with 0.5% proparacaine 
topical anesthetic eye drops or an equivalent 
topical ophthalmic anesthetic.  Place the 
soaked applicators, side by side, gently but 
firmly on the conjunctival surface at the area 
of the entry site described below in Step 10 
and hold in place for approximately 1 
minute.  
Same as DE-109 
 
5. Insert sterile eyelid speculum. 
Same as DE-109 
 
6. Place sterile eye drape over study eye. 
Same as DE-109 
 
7. Prior to starting the injection procedure,  
DE-109 should have been prepared as 
described in Section 6.2.2, with the 
appropriate dose of IP drawn into a 250 µL 
single-use plastic syringe. ENSURE THAT 
THERE ARE NO AIR BUBBLES IN THE 
SYRINGE OR NEEDLE HUB. 
Removal and thawing procedures 
are the same for Sham as for  
DE-109 (Section 6.2.2). A syringe 
loading procedure similar to  
DE-109 should be performed; no 
drug product will be drawn up 
into the syringe. 
 
8. If the subject is phakic, the entry site is 
recommended to be 3.5 mm to 4.0 mm 
peripheral to the limbus. If the subject is 
aphakic or pseudophakic the entry site is 
recommended to be 3.0 mm to 3.5 mm 
peripheral to the limbus. An inferior 
injection site is recommended. A caliper may 
be used to identify the needle entry site.  The 
intravitreal injection site may be modified at 
the unmasked investigator’s discretion.

Immediately after each IP administration, the unmasked investigator or designee will conduct a safety 
check (finger count, hand motion, and light perception).  
Prednisolone acetate eye drops are to be started after each IP administration and continued for 8 days, 
according to the following schedule:  4 times per day for 4 days (including the day of IP 
administration) followed by 2 times per day for 4 days, then stop. 
6.2.4. 
Investigational Product Accountability 
The investigator or designee is responsible for ensuring that an inventory is conducted upon 
receipt of the clinical supplies. The form documenting receipt of clinical supplies should be 
completed, signed, and returned as directed. A copy must be maintained at the site for the 
investigator’s records.   
The investigator or designee is responsible for ensuring that a current record is kept of the 
inventory and dispensing of all IP.  This record will be made available to the study monitor (or 
designee) to account for all clinical supplies. Any significant discrepancy and/or deficiency must 
be recorded with an explanation. 
All supplies sent to the investigator site must be accounted for and in no case will IP be used in 
any unauthorized situation. It is the responsibility of the investigator to return any used and 
unused supplies to the Santen (or designee) at the end of the study. 
6.2.5. 
Investigational Product Handling and Disposal 
All used/un-used vials of IP supplied by Santen must be fully accounted for by the study 
monitor. Accountability will be documented by use of drug accountability forms. During the 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution

study as directed by Santen and/or when the trial is completed, used/un-used vials will be 
returned to Santen or designee, or destroyed at the site at the direction of Santen.  
6.3. 
Measures to Minimize Bias: Randomization and Masking 
For the double-masked period, eligible subjects (total sample size of approximately 200 subjects) 
will be randomized in a 2:2:1 ratio to the DE-109 440 µg arm (80 subjects), the Sham arm  
(80 subjects), and the Dummy arm (40 subjects). The randomization will be stratified by baseline 
systemic (oral) corticosteroid use (yes /no), number of subject’s enrolled eyes (1 eye/2 eyes), and 
region (US/non-US). A separate permuted-block randomization with a fixed block size will be 
generated for each stratum. A computer algorithm for random number generation will be used to 
generate the randomization and an IWRS will be used to administer the randomized assignment 
of subject eyes to treatment arms. Subjects with both eyes enrolled will be assigned to the same 
treatment arm in both eyes. 
The 6-month, comparative period of the study is double-masked and sham-controlled. The sham 
procedure mimics an intravitreal injection (the blunt end of an empty syringe is pressed against 
an anesthetized eye). To retain the masking of the investigator, a separate, unmasked investigator 
will be responsible for administering the IP (DE-109 intravitreal injections and sham). The 
masked investigator will conduct assessments prior to IP administration; the unmasked 
investigator will administer the IP and conduct the post-administration assessments. Thus, the 
treatment assignments will be masked to Santen (except Clinical Supply and Quality Assurance 
personnel, as required), study subjects, and masked investigators.  
The dummy arm is included in the double-masked period of the study to help ensure masking of 
treatment assignment given the use of a sham control. All subjects randomized to the dummy 
arm receive intravitreal injections of DE-109 every 2 months at an undisclosed fixed dose of 
44 µg to 880 µg (doses of DE-109 in this range have previously been shown to have an 
acceptable safety profile). The dose in this arm will not vary between participating sites or 
subjects randomized to this arm. Except for a limited number of Santen employees in Clinical 
Supply and Quality Assurance as required, the dose of DE-109 in the dummy arm will remain 
undisclosed to investigators, CROs, and Santen employees involved in the study conduct.  
Separate IP supplies will be assigned to each study eye. At each visit at which IP is to be 
administered, if one eye is enrolled, the IWRS will assign one specific IP vial for administration 
to the subject’s study eye; if both eyes are enrolled, the IWRS will assign one specific IP vial for 
administration to the subject’s left study eye and one specific IP vial for administration to the 
subject’s right study eye. 
A central Reading Center will be used for the fluorescein angiography, fundus photography, and 
OCT assessments. All central readers will be masked to each subject’s IP assignment.  
In case of an emergency, the investigator has the sole responsibility for determining if 
unmasking of a subject’s treatment assignment is warranted. If the investigator decides that 
unmasking is warranted, the investigator should make every effort to contact the medical monitor 
(Table 1) prior to unmasking a subject’s treatment assignment unless this could delay emergency 
treatment of the subject. Santen must be notified as soon as possible if the IP masking of a 
subject is broken. The date, time, and reason for the unmasking must be recorded in the source 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 41 of 133 
documents. For unmasking, the randomized treatment assignment of a subject can be obtained 
from the IWRS by designated individuals following a specific IWRS unmasking procedure.  
An independent statistical and programming team will be used to perform the planned interim 
analysis of unmasked data and the Data Monitoring Committee (DMC) will review the results 
and make recommendations based on the findings. To unmask the data for the analysis, a 
designee from the independent statistical and programming team will obtain the randomization 
codes directly from the external randomizer, without involvement of Santen. Review of 
unmasked data by the DMC will only occur in closed DMC sessions without participation of 
Santen personnel. The planned interim analysis will be specified in greater detail in the SAP and 
in the DMC charter.  
6.4. 
Investigational Product Compliance 
Compliance with the dosing schedule specified in this protocol is critical to obtain reliable 
efficacy and safety data. The administration of each dose of IP to each subject’s study eye(s) will 
be documented by the investigator/staff and recorded in the electronic Case Report Forms 
(eCRFs). The study monitors will verify eCRFs and other pertinent data to confirm each subject 
is attending visits, undergoing procedures, and receiving treatment with IP per protocol. 
6.5. 
Concomitant Therapy 
6.5.1. 
Collection of Prior and Concomitant Medication Information 
At Screening, information on prior and concomitant medications taken within the previous 
90 days will be collected. At each study visit, subjects should be questioned concerning any new 
medications or changes in their current medications since their previous study visit and the 
information should be recorded in the eCRF. Medications given specifically for antiseptic 
preparation of the study eye should be recorded as concomitant medications.  
For all medications, the generic name, indication, route of administration, frequency, dose, start 
date, and stop date (if applicable) will be collected; for combination products, the brand name 
will also be documented.  
6.5.2. 
Subjects with Glaucoma: Continuation of Ocular Hypotensive Medication 
Subjects with glaucoma are permitted to continue their prescribed ocular hypotensive medication 
during the study. Any required changes to prescribed ocular hypotensive medications and/or 
discontinuation of ocular hypotensive medications are allowed during the study, per the 
investigator’s judgement. 
6.5.3. 
Tapering of Systemic Corticosteroid Therapy 
For study eligibility, subjects receiving systemic (oral) corticosteroid therapy will be required to 
titrate the dose as needed such that they remain on a stable oral prednisone-equivalent dose 
between ≥15 mg/day and ≤40 mg/day that has remained stable for at least 1 week (7 days) prior 
to and including Day 1. The Intent-to-Taper population is defined as those subjects who are 
receiving oral corticosteroid therapy on Day 1. Starting on Day 1, the corticosteroid dose of these 
subjects should be reduced weekly over a maximum of 8 weeks to discontinuation (0 mg/day) 
according to the following tapering schedule: 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 42 of 133 
 Reduce by 10 mg weekly until a dose of 20 mg is reached 
 Then reduce by 5 mg weekly until a dose of 10 mg is reached 
 Then reduce by 2.5 mg weekly until reaching 0 mg 
If the above-suggested tapering scheme needs to be amended significantly, the investigator must 
consult with the study medical monitor. 
6.5.4. 
Continuation of Stable Doses of Topical Ocular Corticosteroid Medication, 
Topical Ocular Non-Steroidal Anti-Inflammatory Medication, or Selected 
Immunosuppressants 
Use of difluprednate ophthalmic emulsion eye drops in the study eye(s) within 7 days prior to 
Day 1 is prohibited. Difluprednate ophthalmic emulsion eye drops are prohibited throughout the 
duration of the study. Subjects being treated with other topical corticosteroid eye drops or with 
topical non-steroidal anti-inflammatory eye drops must have received stable dosing (same 
medication type and frequency of use) for at least 7 days prior to Day 1 in order to be eligible for 
enrollment in the study. These subjects will be allowed to continue the therapy at stable dosing 
during the study (same medication type and frequency of use). Decreases and termination of 
dose are allowed during the study. Similarly, subjects being treated with one of the following: 
methotrexate, azathioprine, or mycophenolate mofetil must have received a stable dose for at 
least 30 days prior to Day 1 with the expectation that the dose will remain stable until the end of 
the trial. These subjects should continue the therapy at a stable dose during the study.  
6.5.5. 
Protocol-Specified Medications Pre and Post Investigational Product 
Administration 
Below are medications to be administered pre and post IP administration.  
Pre IP administration: 
 Pupil dilation: 1% Mydriacyl and 2.5% phenylephrine or equivalent 
 Ocular antisepsis: 5% povidone iodine (also see Table 6, IP administration 
procedure) 
 Topical anesthetic: recommended 0.5% proparacaine hydrochloride or equivalent 
(also see Table 6, IP administration procedure).  
Adjunctive administration of subconjunctival anesthesia is permitted at the discretion of the 
unmasked Investigator. 
Post IP administration: 
 Topical corticosteroid: Prednisolone acetate eye drops are to be started after each IP 
administration and continued for 8 days, according to the following schedule: 4 times 
per day for 4 days (including the day of IP administration) followed by 2 times per 
day for 4 days, then stop. Subjects that are already receiving a stable dose of 
prednisolone acetate eye drops as concomitant therapy should contact the medical 
monitor prior to IP administration to discuss adjusting of the dosing frequency.

Rescue Therapy 
Rescue therapy is defined as any treatment that would have a therapeutic effect on NIU-PS, other 
than intravitreal DE-109. Other protocol-allowed or specified medications that are not considered 
rescue therapy are listed in Section 6.5.7. 
The following are examples of rescue therapies: 
 Systemic corticosteroid therapy (except as described in Section 6.5.7) 
 New systemic treatment with an immunosuppressant agent 
 Increase in dose of ongoing therapy with methotrexate, azathioprine, or 
mycophenolate mofetil (see inclusion criteria Section 5.1, #6) 
 Anti-vascular endothelial growth factor therapy (anti-VEGF) 
 New or increased dose/frequency of topical ocular corticosteroid to the study eye (see 
inclusion criteria Section 5.1, #8) 
 New or increased dose/frequency of topical ocular nonsteroidal anti-inflammatory 
agent to the study eye (see inclusion criteria Section 5.1, #8) 
 Ocular or periocular corticosteroid injection to the study eye 
 Use of difluprednate ophthalmic emulsion eye drops in the study eye 
 Vitrectomy in the study eye 
Because rescue therapies such as those noted above may or will have a therapeutic effect on the 
uveitis in the posterior segment, they are prohibited unless worsening of uveitis in the study eye 
is observed satisfying one or more of the following three rescue criteria:  
1. Worsening of uveitis in the study eye as indicated by at least a 2-step increase in VH 
score (i.e., 0 to ≥ 2+, 0.5+ to ≥ 3+, 1+ to ≥ 3+, 1.5+ to ≥ 4+, or 2+ to ≥ 4+)  as compared 
to the baseline (Day 1) VH score or the best achieved VH score post baseline. 
2. Severe deterioration of vision in the study eye due to worsening of uveitis that is 
indicated by at least doubling of the visual angle (BCVA loss of 3 or more lines 
[≥15 ETDRS letters]) as compared to baseline (Day 1) BCVA. 
3. New or worsening retinal or choroidal uveitic lesion(s) in the study eye determined by 
clinical examination, as compared to baseline. 
When deemed medically necessary, rescue therapy may be administered at the discretion of the 
investigator, even if none of the protocol-specified rescue criteria noted above are satisfied. The 
investigator should contact the study medical monitor to discuss the rescue treatment plan prior 
to the administration of rescue therapy. If the investigator is unable to reach the medical monitor, 
rescue treatment should be administered per the investigator’s clinical judgment and the medical 
monitor should be notified as soon as possible to discuss future on-study treatment plans for the 
subject.  
If both eyes are enrolled and rescue therapy for one of the two enrolled study eyes is required, 
local rather than systemic therapy is encouraged, if appropriate, because systemic therapies will 
affect the response in the other study eye.

Confidential 
Page 44 of 133 
If rescue therapy is administered, the generic name, indication, route of administration, 
frequency, dose, start date, and stop date (if applicable) will be recorded in the eCRF.  
Satisfaction of any of the protocol-specified rescue criteria noted above also satisfies the 
definition of an ESI of clinically significant new or worsening of uveitis, requiring reporting 
within 24 hours of knowledge of the event as described in Section 8.2.13. 
6.5.7. 
Protocol-Allowed or Specified Medications not Considered Rescue Therapy 
Protocol-allowed or specified medications NOT considered rescue therapy are as follows:  
 Investigational product (DE-109, Sham, Dummy). 
 Oral corticosteroids administered in accordance with the protocol-specified tapering 
schedule (Section 6.5.3).  
 Ongoing stable dose/frequency of corticosteroid eye drops is permitted, non-steroidal 
anti-inflammatory eye drops, methotrexate, azathioprine, or mycophenolate mofetil, 
as allowed by the protocol.  
 The protocol-specified administration of prednisolone acetate eye drops following 
each IP administration.  
6.5.8. 
Prohibited Concomitant Medications or Treatments 
Any treatment that would have a therapeutic effect on the uveitis in the posterior segment is 
prohibited, as described in Section 6.5.6.  
Refer to the inclusion and exclusion criteria (Section 5.1 and Section 5.2) for other specific 
prohibited concomitant medications or treatments.  
6.6. 
Dose Modification 
In this study, the IP dose/regimen is assigned by randomization. Dose titration or modification is 
not allowed. Rescue therapy is allowed for worsening of uveitis as described in Section 6.5.6.  
6.7. 
Intervention after the End of the Study 
No subsequent intervention is currently planned for subjects completing this 12-month study.

DISCONTINUATION OF INVESTIGATIONAL PRODUCT AND 
SUBJECT DISCONTINUATION/WITHDRAWAL FROM STUDY 
7.1. 
Discontinuation of Investigational Product 
Subjects may be discontinued from IP administration for adverse events, non-compliance with 
study drug, protocol deviation, lack of efficacy, withdrawal by subject, lost to follow-up, study 
termination, or other reasons. The investigator or Santen medical monitor may discontinue a 
subject from further IP administration for reasons related to the best interest of the subject. If a 
subject is discontinued from IP administration at any point during the study, he or she will be 
encouraged to remain in the study and attend all scheduled visits for safety follow up, including 
ocular procedures other than IP administration, through Month 12. If a subject decides not to 
enter into the open-label period, the investigator should discuss the option of early termination 
with the medical monitor. Subjects that have received at least one open-label treatment are 
encouraged to remain in the study and attend all scheduled visits for safety follow up through 
Month 12. 
7.2. 
Subject Early Discontinuation/Withdrawal from the Study 
A subject may withdraw from the study at any time at his/her own request, or may be withdrawn 
at any time at the discretion of the investigator for safety, behavioral, compliance, or 
administrative reasons. This is expected to be uncommon. At the time of discontinuing from the 
study, if possible, an early termination visit will be conducted to collect the data as shown in the 
SoA (Table 3); the subject will be permanently discontinued both from the IP and from the study 
at that time. 
If the subject withdraws consent for disclosure of future information, Santen may retain and 
continue to use any data collected before such a withdrawal of consent. If a subject withdraws 
from the study, he/she may request destruction of any samples taken and not tested, and the 
investigator must document this in the site study records. 
7.3. 
Lost to Follow-up 
A subject will be considered lost to follow-up if he or she repeatedly fails to return for scheduled 
visits and is unable to be contacted by the study site. The following actions must be taken if a 
subject fails to return to the clinic for a required study visit: 
 The site must attempt to contact the subject and reschedule the missed visit as soon as 
possible and counsel the subject on the importance of maintaining the assigned visit 
schedule and ascertain whether or not the subject wishes to and/or should continue in 
the study. 
 Before a subject is deemed lost to follow up, the investigator or designee must make 
every effort to regain contact with the subject (where possible, 3 telephone calls and, 
if necessary, a certified letter to the subject’s last known mailing address or local 
equivalent methods). These contact attempts should be documented in the subject’s 
medical record.

Unscheduled Visits 
If a subject requires evaluation between scheduled visits, applicable study procedures may be 
performed as specified in the protocol (e.g., if performed, assessment in both eyes for visual 
acuity must follow protocol-specified BCVA evaluation using ETDRS chart). At a minimum, 
unscheduled visits should include (1) assessment for adverse events and (2) recording of 
concomitant medications. DE-109 will not be administered at an unscheduled visit.

1+  
Mild blurring of the retinal vessels and optic nerve  
1.5+  
Optic nerve head and posterior retina view obstruction greater than 1+ but less than 
2+  
2+  
Moderate blurring of the optic nerve head  
3+

4+  
Optic Nerve head not visible  
A VH score of 1.5+ will be used to categorize subjects with a VH score of greater than 1+ but less 
than 2+ 
 
VH scores will be recorded during slit-lamp biomicroscopy evaluations. Study eligibility with 
respect to VH will be confirmed by central reading of fundus photographs; the reading center 
procedures are detailed in a procedure manual.  
8.1.20. 
Best-Corrected Visual Acuity 
The best-corrected visual acuity (BCVA) will be recorded (for both eyes) using ETDRS charts 
and the total number of letters at 4 meters and 1 meter will be recorded.  If a subject’s visual 
acuity is so poor that he/she cannot read any chart letters when tested at 1 meter, then the 
subject’s ability to count fingers, detect hand motion, or have light perception should be 
evaluated. Refer to Section 12.2 for details of the visual acuity assessments.

The National Eye Institute Visual Functioning Questionnaire - 25 (VFQ-25), version 2000, 
including the appendix questions, will be administered (National_Eye_Institute, 2000). The 
VFQ-25 is a patient reported outcome that was designed to measure the dimensions of self-
reported vision-targeted health status that are most important for persons who have chronic eye 
diseases. The VFQ-25 is provided in Section 12.1.  
8.2. 
Safety Assessments 
This section describes the following safety assessments: slit-lamp biomicroscopy, indirect 
ophthalmoscopy, IOP, fundus photography, fluorescein angiography, laboratory tests (serum 
chemistry, hematology, and urinalysis), pregnancy testing, physical examination, and vital signs. 
Assessment of AEs and SAEs is described in Section 8.3. Assessment of BCVA and OCT are 
described in Section 8.1.20 and Section 8.1.21, respectively. Planned time points for all 
assessments are provided in the SoA (Table 3) and details by visit are provided in Section 8.1.1. 
8.2.1. 
Slit-Lamp Biomicroscopy 
Slit-lamp biomicroscopy will be used to examine eye structures for both eyes during screening 
and at each follow-up study visit. At visits when IP is administered, slit-lamp biomicroscopy will 
be performed prior to IP administration and then again within 30 minutes after IP administration. 
Areas to be assessed include vitreous, lids, conjunctiva, cornea, anterior chamber cells and flare, 
iris, pupil, lashes, ocular motility, lens, and cataract status.  
8.2.2. 
Vitreous Cells 
Slit-lamp biomicroscopy will be used to assess vitreous cells. The following SUN scale for 
vitreous cell count will be used to measure vitreous cells:

8.2.5. 
Terminology for Biomicroscopy Findings 
Consistency in the recording of biomicroscopy findings will be facilitated by providing a 
selection of possible terms on the eCRF for each area to be assessed; additional terms may be 
recorded as needed. Whenever possible, consistency should be maintained in the use of terms 
between examinations.  

Protocol 010906IN, LUMINA

8.2.6. 
Indirect Ophthalmoscopy 
Indirect ophthalmoscopy will be used to examine the retina of each eye during screening and at 
each follow-up study visit, and will be performed with pupil dilation. At visits when IP is 
administered, indirect ophthalmoscopy will be performed prior to IP administration and then 
again within 30 minutes after IP administration. Areas to be assessed include retina vessels, 
macula, fovea, periphery, optic nerve, and vitreous. Consistency in the recording of findings will 
be facilitated by providing a selection of possible terms on the eCRF for each area to be 
assessed; additional terms may be recorded as needed. 
8.2.7. 
Intraocular Pressure 
Intraocular Pressure (IOP) will be measured during screening and at each follow-up study visit. 
The examiner will measure IOP in each eye and record results in mmHg (e.g., 24). A single 
measurement is made to obtain a determination of IOP. The same contact tonometer employing 
the investigator’s standard technique will be used throughout the study.  
At visits when IP is administered, IOP will be measured prior to IP administration and at 
approximately 40 (±10) minutes after IP administration. See the visit details of dosing visits 
(e.g., Day 1 visit details, Section 8.1.3). 
Tonometer calibration: The tonometer must be calibrated for accuracy before the first subject 
undergoes screening, and periodically according to manufacturer’s instructions thereafter, until 
the last subject has exited the study. For checking calibration, follow the manufacturer’s 
instructions. If when checked, the variation is within ±2 mmHg, the tonometer is considered 
adequately calibrated. However, if the variation exceeds this amount, the tonometer should be 
sent for repair and a different, adequately calibrated instrument should be used for IOP 
measurement. The date of each calibration, along with the name and signature (or initials) of the 
person who performed the calibration, must be documented. The tonometer calibration record 
will be retained as a part of the study record.  
8.2.8. 
Fundus Photography 
At each visit, digital color fundus photography will be taken of both eyes using reading center 
certified photographers, equipment, and standardized protocols. Fundus photographs will be 
submitted to a central reading center. The procedures are detailed in the reading center procedure 
manual.  
8.2.9. 
Fluorescein Angiography 
Wide field fundus fluorescein angiography (FA) will be taken of both eyes using reading center 
certified photographers (Day 1), equipment and a standardized protocol at the visits as specified 
in the SoA (Table 3). Refer to the reading center procedure manual for the complete protocol.  
8.2.10. 
Clinical Safety Laboratory Assessments 
 Fasting or non-fasting blood samples and urine samples will be obtained for 
laboratory assessments according to the SoA (Table 3). Samples will be sent for 
analysis to the designated central laboratory. Note: Blood and urine samples should 
be collected before injection of fluorescein. 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 59 of 133 
 See Section 10.2 for the clinical laboratory tests to be performed.  
 The investigator must review the laboratory report, document this review, and record 
any clinically relevant changes occurring during the study in the AE section of the 
CRF. The laboratory reports must be filed with the source documents. Clinically 
significant abnormal laboratory findings are those which are not associated with the 
underlying disease (uveitis), unless judged by the investigator to be more severe than 
expected for the subject's condition. Lab shifts within the range of normal should 
generally not be considered AEs.  
 All laboratory tests with values considered clinically significantly abnormal during 
participation in the study or within 60 days after the last IP administration should be 
repeated until the values return to normal or baseline or are no longer considered 
clinically significant by the investigator or Santen medical monitor. 
 If such values do not return to normal/baseline within a period of time judged 
reasonable by the investigator, the etiology should be identified, and Santen 
notified. 
 All protocol-required laboratory assessments, as defined in Section 10.2, must be 
conducted in accordance with the laboratory manual and the SoA (Table 3). 
 If laboratory values from non-protocol specified laboratory assessments 
performed at the institution’s local laboratory require a change in subject 
management or are considered clinically significant by the investigator (e.g., SAE 
or AE or dose modification), then the results must be recorded in the eCRF. 
A retest of screening laboratory tests is permitted only if there is reason to believe the initial 
value was either due to a sample processing error or an extenuating circumstance. 
8.2.11. 
Physical Examination 
A full body systematic physical examination will be conducted by the investigator/designee.  
8.2.12. 
Vital Signs 
Systolic and diastolic blood pressure should be measured only after the subject has been in a 
sitting position for at least 5 minutes, and will be recorded in millimeters of mercury (mmHg). 
Measurement with an automated sphygmomanometer is acceptable.  
Heart rate should be measured only after the subject has been in a sitting position for at least 2 
minutes, and will be recorded in beats per minute (bpm). 
Temperature should be measured.  
8.2.13. 
Events of Special Interest 
Events of Special Interest (ESIs) are medical events both anticipated and unanticipated that may 
have particular impact on the benefit/risk profile of DE-109 and therefore may require more 
detailed characterization. The DE-109 Investigational Brochure is the source for defining the 
DE-109 ESIs and should be consulted for further information.  
 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 60 of 133 
The DE-109 ESIs are specific to the study eye only and are as follows:  
 Clinically significant new or worsening of uveitis, defined as satisfaction of any of 
the following:  
 Worsening of uveitis in the study eye as indicated by at least a 2-step increase in 
VH score (i.e., 0 to ≥ 2+, 0.5+ to ≥ 3+, 1+ to ≥ 3+, 1.5+ to ≥ 4+, or 2+ to ≥ 4+) as 
compared to the baseline (Day 1) VH score or the best achieved VH score post-
baseline. 
 Severe deterioration of vision in the study eye due to worsening of uveitis that is 
indicated by at least doubling of the visual angle (loss of 3 or more lines [≥15 
ETDRS letters]) as compared to baseline (Day 1) BCVA. 
 New or worsening retinal or choroidal uveitic lesion(s) in the study eye as 
compared to baseline (Day 1). 
 New or worsening uveitis otherwise deemed clinically significant by the 
investigator in the study eye as compared to the baseline (Day 1). 
Note: When documenting clinically significant new or worsening uveitis, the anatomic 
location (e.g., anterior uveitis, intermediate uveitis, posterior uveitis, or panuveitis ) 
should be specified.  
 Endophthalmitis / Sterile Endophthalmitis in the study eye – A guided questionnaire 
is provided as part of the eCRFs to facilitate the documentation of endophthalmitis 
and sterile endophthalmitis. Endophthalmitis is also to be reported as an SAE 
(Section 10.4). 
 Traumatic cataract in the study eye 
 Vitreoretinal hemorrhage in the study eye 
 Drug depot in visual axis in the study eye 
 Retinal detachment (also to be reported as an SAE, Section 10.4) in the study eye 
 Increased IOP (> 10 mmHg as compared to baseline). Note that certain instances of 
increased IOP are to be reported as an SAE (IOP >35 mmHg that persists for at least 
7 days despite pharmacologic therapy, Section 10.4) in the study eye.  
 Cataract (new or worsening from baseline) in the study eye 
 Investigational product administration error considered to be significant by the 
investigator (examples include administration of IP from an incorrect kit and IP 
administration error attributed to some aspect of the instructions provided) 
 Pregnancy (see Section 8.2.14) 
Additionaly below are the two (pregnancy and medication error) ESIs that need to be reported 
regardless of the study eye involvement:  
Most ESIs are AEs, some ESIs may also be SAEs, and some ESIs may not be AEs (e.g., an IP 
administration error may not be an AE; pregnancies are not AEs). However, all ESIs should be 
reported within 24 hours of knowledge of the event using applicable eCRFs and recording as 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021

much information as available. ESIs should be followed by the investigator to the same extent as 
SAEs, that is, until the event is determined to be resolved, irreversible, chronic, stable, the 
subject withdraws consent, or no further information can be reasonably obtained. Monitoring for 
pregnancy and follow-up of pregnancy is described in Section 8.2.14. 
8.2.14. 
Pregnancy Testing, Monitoring, and Reporting 
8.2.15. 
Pregnancy Testing 
If the subject is a woman of child-bearing potential, a blood sample will be obtained during 
screening for a serum pregnancy test. Samples will be sent for analysis to the central laboratory. 
Urine samples will be collected for pregnancy tests prior to IP administrations as specified in the 
SoA (Table 3). Urine samples will be analyzed at the site with results available prior to 
administration of IP. 
8.2.16. 
Pregnancy Monitoring and Reporting Procedures 
Pregnancy in female subjects and female partners of male subjects will be monitored starting 
from screening through the Month 12/Exit/Early Termination visit.  
Although not considered an AE or SAE, pregnancy is an ESI and requires careful monitoring and 
follow up. If a pregnancy is reported by a study subject (or in the partner of a study subject), the 
investigator must:  
 Inform Santen within 24 hours of learning of the pregnancy. 
 If the pregnancy has occurred in a study subject, discontinue further IP administration 
and/or withdraw the subject from the study. 
 Report pregnancy information on the eCRF following instructions. 
 Follow the pregnancy until outcome is known.  Santen will request specific follow-up 
on a case-by-case basis.  
Additional details regarding collection, reporting, and follow-up of pregnancy is provided below: 
Female subjects who become pregnant: The investigator will collect pregnancy information on 
any female subject who becomes pregnant while participating in this study. Information will be 
recorded on the appropriate form and submitted to Santen within 24 hours of learning of a 
subject's pregnancy. The subject will be followed to determine the outcome of the pregnancy. 
The investigator will collect follow-up information on the subject and the neonate and the 
information will be forwarded to Santen. Generally, follow-up will not be required for longer 
than 6 to 8 weeks beyond the estimated delivery date. Any termination of pregnancy will be 
reported, regardless of fetal status (presence or absence of anomalies) or indication for the 
procedure. While pregnancy itself is not considered to be an AE or SAE, any pregnancy 
complication or elective termination of a pregnancy will be reported as an Event of Special 
Interest (ESI). Abnormal pregnancy outcomes (e.g., spontaneous abortion, fetal death, stillbirth, 
congenital anomalies, ectopic pregnancy) are considered SAEs and will be reported as such. Any 
post-study pregnancy-related SAE considered reasonably related to the IP by the investigator 
will be reported to Santen. While the investigator is not obligated to actively seek this 
information in former study subjects, he or she may learn of an SAE through spontaneous 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution

reporting. Any female subject who becomes pregnant while participating in the study will 
discontinue IP and be withdrawn from the study.  
Male subjects with partners who become pregnant: The investigator will attempt to collect 
pregnancy information on any male subject’s female partner who becomes pregnant while the 
male subject is in this study. After obtaining the necessary signed informed consent from the 
pregnant female partner directly, the investigator will record pregnancy information on the 
appropriate form and submit it to Santen within 24 hours of learning of the partner’s pregnancy. 
The female partner will also be followed to determine the outcome of the pregnancy. Information 
on the status of the mother and child will be forwarded to Santen. Generally, the follow-up will 
be no longer than 6 to 8 weeks following the estimated delivery date. Any termination of the 
pregnancy will be reported regardless of fetal status (presence or absence of anomalies) or 
indication for the procedure. 
8.3. 
Adverse Events and Serious Adverse Events 
The definitions of AE and SAE are provided in Section 10.4. 
Adverse events will be reported by the subject (or, when appropriate, by a caregiver, surrogate, 
or the subject's legally authorized representative) to the masked or unmasked investigator. 
The masked and unmasked investigator and any qualified designees are responsible for 
detecting, documenting, and recording events that meet the definition of an AE or SAE and 
following up on-going AEs and SAEs as specified below.  
8.3.1. 
Time Period and Frequency for Collecting AE and SAE Information 
Adverse events and SAEs will be monitored for and collected at the time points specified in the 
SoA (Table 3), from the signing of the Informed Consent Form (ICF) until the subject 
withdrawal or the scheduled exit visit. (Note: Although AEs will be monitored for and collected 
prior to IP administration, the statistical data analysis will determine and summarize treatment-
emergent AEs, i.e., those AEs that began or worsened in severity after the first IP 
administration.) 
All SAEs will be recorded and reported to Santen or designee immediately and under no 
circumstance should this exceed 24 hours, as indicated in Section 10.4. The investigator will 
submit any updated SAE data to Santen within 24 hours of it being available.  
Investigators are not obligated to monitor for new AEs or SAEs after conclusion of the study 
participation. However, if the investigator learns of any SAE, including a death, at any time after 
a subject has been discharged from the study, and he/she considers the event to be reasonably 
related to the IP or study participation, the investigator must promptly notify Santen. 
8.3.2. 
Method of Detecting AEs and SAEs 
The method of recording, evaluating, and assessing causality of AEs and SAEs and the 
procedures for completing and transmitting SAE reports are provided in Section 10.4. During the 
double-masked period, regardless of the source of the reported occurrence of an AE in a subject, 
the masked investigator will assess the causality of the AE. 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 63 of 133 
Care will be taken not to introduce bias when detecting AEs and/or SAEs. Open-ended and 
non-leading verbal questioning of the subject is the preferred method to inquire about 
AE occurrences. 
8.3.3. 
Follow-up of AEs and SAEs 
All reported AEs should be followed by the investigator until resolution or until the subject’s 
participation in the study ends.  
More extensive follow-up is required for (1) SAEs and (2) IP related AEs that lead to or cause 
early withdrawal of a subject from the study. Both of these types of events should be followed by 
the investigator until the event is determined to be resolved, irreversible, chronic, stable, the 
subject withdraws consent, or no further information can be reasonably obtained. As described in 
Section 8.2.13, ESIs are followed up to this same extent.  
In addition to the above, Santen (or designee) may request, on a case-by-case basis, follow up of 
events/subjects beyond the scheduled exit visit.  
Prior to database lock, follow-up information on an individual SAE or AE (or ESI) will be 
entered into the eCRF. When database lock has already been completed, or if information 
requested by Santen is not part of the eCRF, the site’s response to follow-up requests should be 
emailed or documented on paper and faxed to Santen Global Pharmacovigilance (see Table 1).  
8.3.4. 
Regulatory Reporting Requirements for SAEs 
Prompt notification by the investigator to Santen of an SAE is essential so that legal obligations 
and ethical responsibilities towards the safety of subjects and the safety of a study intervention 
under clinical investigation are met. 
Santen has a legal responsibility to notify both the local regulatory authority and other regulatory 
agencies about the safety of a study intervention under clinical investigation. Santen will comply 
with country-specific regulatory requirements relating to safety reporting to the regulatory 
authority, Institutional Review Boards (IRB)/Independent Ethics Committees (IEC), and 
investigators. 
Santen will prepare investigator safety reports for suspected unexpected serious adverse 
reactions (SUSAR) according to local regulatory requirements and Santen policy and forward 
them to investigators as necessary. An investigator who receives an investigator safety report 
describing an SAE or other specific safety information (e.g., summary or listing of SAEs) from 
Santen will review and then file it along with the Investigational Brochure and will notify the 
IRB/IEC, if appropriate according to local requirements. 
8.4. 
Pharmacogenomics 
All subjects participating in the study will have the option to participate in blood sampling for 
pharmacogenomics and this will be consented to collect this optional test. Subjects who do not 
wish to participate in the pharmacogenomic sampling may still participate in the study. 
on Day 14 visit, but may be collected 
at any time during the study or at a separate post study visit, if necessary, as shown in the SoA

STATISTICAL CONSIDERATIONS 
Unless specified otherwise, efficacy measures will be summarized by planned (i.e., randomized) 
treatment and based on the FAS population, and safety measures will be summarized by actual 
treatment received and based on the Safety population. All efficacy endpoint analyses will be 
performed on eyes enrolled in the study (referred to as study eyes). Safety assessments that 
pertain to the eye will be analyzed by the study eye and fellow eye separately. Safety 
assessments that pertain to the subject will be analyzed at the subject level. 
Continuous variables will be summarized using descriptive statistics such as number of 
observations (n), mean, standard deviation, medium, minimum, and maximum.  Categorical 
variables will be tabulated using frequency (n) and percent (%). 
Statistical testing is planned for the analysis of efficacy endpoints of the double-masked period 
only (not safety endpoints) and will assess for superiority of efficacy observed in the test arm 
(440 µg DE-109 every 2 months) compared to the sham control. Statistical testing will not 
involve the dummy arm, which is included in the study to help ensure masking of treatment 
assignments. Unless specified otherwise, the statistical testing will be conducted at a significance 
level of 0.05 (two-sided). Additional details of the statistical methods will be described in the 
Statistical Analysis Plan (SAP). 
All data manipulations, descriptive summaries, and statistical hypothesis testing will be 
performed using SAS Version 9.4 or later. FDA guidance regarding case report tabulations 
(annotated eCRFs, SAS datasets, metadata, and SAS programs) in electronic submissions will be 
followed. Data definition tables will be created for SDTM and ADaM datasets separately.  
9.1. 
Estimands 
 The primary estimand is: Vitreous haze 0 (VH0) response rate in DE-109 440 µg group 
vs. Sham group at Month 5 in all study eyes that received at least one dose of the study 
treatment where all eyes that were rescued due to worsening of uveitis or discontinued 
from the study due to lack of efficacy or due to adverse event before Month 5 will be 
treated as non-responders. For study eyes that were rescued for any other reasons or had 
missing data due to other reasons, imputation by the multiple imputation-based approach 
will be used. 
 The treatment policy estimand is: VH0 response rate in DE-109 440 µg group vs. Sham 
group at Month 5 in all study eyes that received at least one dose of the study treatment 
regardless of whether subjects have received rescue therapy or discontinued from the 
study due to lack of efficacy or due to adverse event. For study eyes that had missing data 
due to any reason, imputation by the multiple imputation-based approach will be used. 
 The composite estimand is: Mean composite score in DE-109 440 µg group vs. Sham 
group at Month 3 and at Month 5 in all study eyes that received at least one dose of study 
treatment. Each study eye will be assigned one of the following scores: 
o Score = 3 if a study eye achieved VH score of 0 at the specified visit without taking 
any rescue therapies that could affect VH score prior to the specified visit  
o Score = 2 if a study eye had at least improved by 2 units in VH (compared to 
baseline) at the specified visit without taking any rescue therapies that could affect 
VH score prior to the specified visit   

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 66 of 133 
o Score = 1 if a study eye achieved VH score of 0.5+ at the specified visit without 
taking any rescue therapies that could affect VH score prior to the specified visit   
o Score = -1 if a study eye got rescued due to worsening of uveitis or discontinued from 
the study due to lack of efficacy or due to adverse event prior to the specified visit 
o Score = 0 if otherwise 
9.2. 
Statistical Hypotheses  
The primary efficacy endpoint (VH 0 response at Month 5) will be analyzed using the Cochran-
Mantel-Haenszel (CMH) test with Row Mean Scores statistic, stratified by the number of 
enrolled eyes from a subject (one eye or two eyes), baseline systemic (oral) corticosteroid use 
(yes or no), and region (US or non-US). The null (H0) and alternative (H1) hypotheses are as 
follows:  
H0: πsham = π440 
H1: πsham ≠ π440 
where πsham and π440 denote the response rate for sham and 440 μg DE-109, respectively.   
9.3. 
Sample Size Determination 
Assuming a 30% VH 0 response rate for DE-109 440 µg group and a 12% response rate for the 
sham treatment group, 160 subjects (80 subjects per arm) is required to achieve 80% power to 
detect such a difference in response rate between the DE-109 440 µg group and the sham 
treatment group using the Pearson’s Chi-square test (two-sided, α = 0.05). Including 
approximately 40 subjects in the dummy arm, a total of approximately 200 subjects with active 
NIU-PS will be randomized in a 2:2:1 ratio to DE-109 440 µg, sham, and dummy arms.  
9.4. 
Populations for Analyses 
The following analysis populations for study analyses are defined: Full Analysis Set (FAS), 
Safety, Per-Protocol (PP), Intent-to-Taper, Macular Edema, Vision 20/40 or Worse: 
 The FAS population will consist of all study eyes that are randomized and received 
at least one administration of study treatment. The FAS population will be the 
analysis population for the primary analysis and will use treatment as randomized.  
 For analyses of ocular AEs and safety parameters assessed per eye, the Safety 
population will consist of all study eyes which received at least one administration of 
IP. For analyses of non-ocular AEs and safety parameters assessed per subject, the 
Safety population will consist of all subjects who received at least one 
administration of IP. 
 The PP population will be a subset of the FAS population. The PP population will be 
the analysis population for sensitivity analyses and will use treatment as randomized. 
Any study eye affected by a significant protocol deviation (such that the outcome to 
treatment could be altered) will be excluded from the PP population. In addition, any 
study eye without the Month 5 VH score will be excluded from the PP population. 
Eyes to be excluded from the PP population will be identified before the unmasking 
of treatment assignments. 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 67 of 133 
 The Intent-to-Taper population will be a subset of the FAS population, consisting 
of study eyes from subjects who were taking systemic (oral) corticosteroids at a stable 
prednisone-equivalent dose between ≥15 mg/day and ≤40 mg/day for at least 1 week 
(7 days) prior to and including on Day 1. The Intent-to-Taper population will be used 
for the analysis of tapering success performed using eyes as randomized.  
 The Macular Edema population will be a subset of the FAS population and will 
consist of study eyes with CST ≥ 300 microns at baseline. 
 The Vision 20/40 or Worse population will be a subset of the FAS population and 
will consist of study eyes with BCVA ≤ 70 ETDRS letters (Snellen equivalent of 
20/40 or worse) at baseline. 
9.5. 
Statistical Analyses 
Details of statistical analyses will be described in the SAP, which will be developed and finalized 
before database lock. This section is a summary of the planned statistical analyses of the primary 
and secondary endpoints (see Table 4). 
9.5.1. 
Handling of Missing Values 
In the analysis of VH 0, VH 0 or 2-unit decrease (improvement), and VH 0 or 0.5+ responses: 
 Subjects who (a) receive rescue therapy for conditions other than worsening of uveitis 
or (b) are rescued due to the worsening of uveitis but do not meet the protocol-
defined rescue criteria, missing VH scores subsequent to receiving rescue therapy will 
be imputed using a multiple imputation-based approach before receiving rescue 
therapy.  
 Missing VH scores of subjects not rescued before Month 5/Month 3 visit will be 
imputed using a multiple imputation-based approach.   
The multiple imputation model will include vitreous haze measures at preceding visits and 
baseline characteristics. The response status will then be determined based on the observed or 
imputed VH scores. 
No imputation is needed for composite score analysis as eyes with missing VH scores will be 
assigned a score of zero, unless they are rescued due to the worsening of uveitis or discontinued 
from the study due to lack of efficacy or adverse event (which will be assigned with a score of    
-1).  
For medical events including AEs, completely or partially missing onset and resolution dates will 
be imputed in a conservative fashion to be detailed in the SAP.  The same rules will be followed 
to impute completely or partially missing start and end dates of non-study medications. 
Unless specified otherwise, descriptive summaries will be based on observed cases.  No 
imputation of missing scores will be implemented.

Efficacy Analyses 
Rescue therapy is defined in Section 6.5.6 and is essentially any treatment that would have a 
therapeutic effect on NIU-PS other than intravitreal DE-109. Rescue therapy is permitted in the 
case of worsening of uveitis that satisfies protocol-defined rescue criteria. The use of rescue 
therapy is considered in assessing the VH response endpoints (VH 0 response, VH 0 or 2-unit 
improvement, and VH 0 or 0.5+ response). In the analysis of these endpoints at a specific follow-
up visit (e.g., Month 5 or Month 3), subjects who met one of the protocol-defined rescue criteria 
will be assessed as non-responders regardless of whether the subjects were rescued or not.

Statistical Analysis Methods 
Primary endpoint: 
VH 0 responsea at Month 5 
For the primary analysis of VH 0 response at Month 5, 
the Cochran-Mantel-Haenszel (CMH) test with Row 
Mean Scores statistic stratified by number of enrolled 
eyes from a subject (one eye or two eyes), baseline 
systemic (oral) corticosteroid use (yes or no), and region 
(US or non-US) will be conducted.  
Logistic generalized estimating equation (GEE) model, 
treatment policy strategy, last-observation-carried-
forward (LOCF) imputation, and multiple imputation 
with tipping point analysis will be used as a sensitivity 
analysis. 
Secondary endpoints: 
Key secondary efficacy endpoints:  
 
Composite endpointb at Month 5 
 
VH 0 response at Month 3 
 
Composite endpoint at Month 3 
A hierarchical approach will be used to control the 
overall Type I error rate associated with the multiple 
comparisons across the primary and the key secondary 
efficacy endpoints.  
If the hypothesis testing for the primary endpoint 
successfully rejects the null hypothesis, the first key 
secondary efficacy endpoint will be tested, and so on.  
All the other secondary efficacy endpoints are 
supportive in nature. Therefore, no formal hypothesis 
testing will be performed on secondary efficacy 
endpoints. Two-sided 95% confidence intervals and 
nominal p-values may be reported for them, and such 
results will be interpreted descriptively in terms of the 
support they provide to the treatment comparisons for 
the primary and the key secondary efficacy endpoints in 
the sense of logical consistency.

Exploratory 
Will be described in the statistical analysis plan 
finalized before database lock. 
Note: Vitreous haze (VH) will be scored using the modified Standardized Uveitis Nomenclature (SUN) scale.  
a VH 0 response (resolution of inflammation) is defined as a VH score of 0 in the study eye at a specified follow up 
visit based on the modified SUN scale. 
b  Refer to composite score scales defined in the composite estimand in this table.   
cVH 0 or 2-unit response is defined as having a VH score of 0 or a decrease (improvement) of at least 2 units (i.e., 
2+ to 0, 3+ to 1+, or 4+ to 2+) from baseline in the study eye in VH score at a specified follow up visit based on 
the modified SUN scale. 
d VH 0 or 0.5+ response (remission of inflammation) is defined as a VH score of 0 or 0.5+ in the study eye at a 
specified follow-up visit based on the modified SUN scale.  
e Corticosteroid tapering success with resolution is defined as achievement of a prednisone-equivalent oral dose of 
0 mg/day and a VH score of 0 in the study eye at a specified follow-up visit. This endpoint is assessed based on 
the Intent-to-Taper population (study eyes of subjects who received systemic [oral] corticosteroids at a stable 
prednisone-equivalent dose of between ≥15 mg/day and ≤40 mg/day that has remained stable for at least 1 week 
[7days] prior to and including on Day 1). 
f BCVA 3-line response is defined as an increase (improvement) of at least 3 lines (15 ETDRS letters) from baseline 
in BCVA at a specified follow-up visit. This endpoint is assessed based on eyes with a baseline best-corrected 
visual acuity (BCVA) ≤70 ETDRS letters (Snellen equivalent of 20/40 or worse).  
9.5.3. 
Subpopulation Analyses  
All the analyses listed in Section 9.5.2 will be repeated on the PP, Intent-to-Taper, Macular 
Edema, and Vision 20/40 or Worse sub-populations. 
9.5.4. 
Safety Analyses 
All safety analyses will be performed on the Safety Population. 
Safety of DE-109 will be assessed by AEs and evaluation with slit-lamp biomicroscopy, indirect 
ophthalmoscopy, BCVA, intraocular pressure (IOP), fundus photography, fluorescein 
angiography, laboratory tests (serum chemistry, hematology, and urinalysis), physical 
examinations and vital signs. 
Besides the overall summary of AEs, subjects with any AE(s) will be tabulated by system organ 
class (SOC) and preferred term specified in MedDRA dictionary. They will also be tabulated by 
SOC, preferred term, and maximum severity. For AE tables, a subject who experienced multiple 
AEs within a SOC or preferred term will be counted only once at the maximum severity for that 
SOC or preferred term. SAEs will be tabulated similarly.  Separate summaries for ocular AEs 
and non-ocular AEs will also be performed. Ocular AEs will be summarized for study eyes and 
fellow eyes separately.  Any ocular AE that occurred simultaneously to both eyes will be counted 
once for both the study eye and the fellow eye.  Injection-procedure related AEs will be tabulated 
by SOC and preferred term. 
AEs leading to death, SAEs, and AEs leading to discontinuation, if any, will be listed separately. 
Events of special interest will be listed by type of event. For other safety variables, descriptive 
summaries of observed score or status, change or shift from baseline, and/or change after 
injection, whichever applicable, will be performed.

Interim Analyses, Primary Analysis, and Analysis of Open-Label 
Period of Study 
An interim analysis is planned when the first 100 subjects complete their Month 5 Visit. There 
are two goals for this interim analysis (1) to assess for futility; and (2) to re-assess the sample 
size. Sample size re-assessment will be performed with the “promising zone” approach as 
follows (Mehta et al., 2011). If the conditional power at the interim analysis is between 50% and 
80%, the suggested sample size increase may be up to 100 subjects (i.e., 50% of the original 
sample size). If, on the other hand, the conditional power is > 80% or < 50%, no change to the 
sample size will take place. If the conditional power is <30%, then the Data Monitoring 
Committee (DMC) would recommend stopping the trial due to futility.  The DMC could 
recommend stopping the trial due to safety concerns at any of the DMC meetings and the interim 
analysis. An independent statistical and programming team will be used to perform this interim 
analysis of unmasked data and the DMC will review the results and make recommendations 
based on the findings. The planned interim analysis will be specified in greater detail in the SAP 
and in the DMC charter.  
The primary analysis of this study is the analysis of the data from the 6-month, double-masked 
period. These data will be quality-checked, soft-locked, and the primary analysis will be 
conducted after all subjects have completed the Month 6 visit or prematurely discontinued from 
the study prior to Month 6. An interim clinical study report will be written documenting the 
primary analysis results.  
Analysis of the open-label period of the study will be performed after the end of the study and 
documented in the final clinical study report.  
9.6.1. 
Data Monitoring Committee (DMC) 
An independent data monitoring committee (DMC) whose members will not be participating in 
the LUMINA study conduct will serve as an advisory board to the Santen senior management 
team. The DMC will periodically review and make recommendations based on interim data; 
unmasked data will only be reviewed in closed DMC sessions without participation of Santen 
personnel. The organization, responsibilities, and procedures of the DMC will be specified in a 
governing charter.

10.1.8. 
Sponsor’s Direct Access to Source Data/Documents and IRB/IEC Materials for 
Monitoring and Audit 
10.1.8.1. Study Monitoring 
Santen or Santen’s designee will be allowed to conduct site visits to the investigation facilities 
for the purpose of monitoring any aspect of the study.  The investigator agrees to allow the 
monitor to inspect the drug storage area, investigational product stocks, drug accountability 
records, subject charts and study source documents, and other records relative to study conduct. 
Before an investigational site can enter a subject into the study, a representative of the Sponsor 
will visit the investigational study site to: 
 Determine the adequacy of the facilities 
 Discuss with the investigator(s) and other personnel their responsibilities with regard 
to protocol adherence, and the responsibilities of Santen or its representatives.  This 
will be documented in a Clinical Study Agreement between Santen or its designee 
and the investigator. 
During the study, a monitor from Santen or representative will have regular contacts with the 
investigational site, for the following: 
 Provide information and support to the investigator(s) 
 Confirm that facilities remain acceptable 
 Confirm that the investigational team is adhering to the protocol, that data are being 
accurately recorded in the case report forms, and that investigational product 
accountability checks are being performed 
 Perform source data verification.  This includes a comparison of the data in the case 
report forms with the subject’s medical records at the hospital or practice, and other 
records relevant to the study.  This will require direct access to all original records for 
each subject (e.g., clinic charts). 
 Record and report any protocol deviations not previously sent to Santen. 
 Confirm non-serious AEs and SAEs have been properly documented on CRFs and 
confirm any safety information requiring expedited reporting to Santen Inc PVU 
(including SAEs, ESIs and Pregnancies) have been forwarded to Santen and those 
SAEs that met criteria for reporting have been forwarded to the IRB/IEC. 
The monitor will be available between visits if the investigator(s) or other staff need information 
or advice.

10.1.8.2. Audits and Inspections 
Authorized representatives of Santen, a regulatory authority (national or foreign), an Independent 
Ethics Committee or an Institutional Review Board may visit the site to perform audits or 
inspections, including source data verification.  The purpose of an audit or inspection is to 
systematically and independently examine all study-related activities and documents to 
determine whether these activities were conducted, and data were recorded, analyzed, and 
accurately reported according to the protocol, Good Clinical Practice guidelines of the 
International Council for Harmonisation, and any applicable regulatory requirements.  The 
investigator should contact Santen immediately if contacted by a regulatory agency about an 
inspection. 
10.1.9. 
Study and Site Closure 
Santen’s designee reserves the right to close the study site or terminate the study at any time for 
any reason at the sole discretion of Santen. Study sites will be closed upon study completion. A 
study site is considered closed when all required documents and study supplies have been 
collected and a study-site closure visit has been performed. 
The investigator may initiate study-site closure at any time, provided there is reasonable cause 
and sufficient notice is given in advance of the intended termination. 
Reasons for the early closure of a study site by Santen or investigator may include but are not 
limited to: 
 Failure of the investigator to comply with the protocol, the requirements of the 
IRB/IEC or local health authorities, Santen's procedures, or GCP guidelines 
 Inadequate recruitment of subjects by the investigator 
 Discontinuation of further development of the investigational product

Adverse Events: Definitions and Procedures for Recording, 
Evaluating, Follow-up, and Reporting 
Table 10: 
Definition of AE 
AE Definition 
 
An AE is any untoward medical occurrence in a patient or clinical study participant, temporally 
associated with the use of study intervention, whether or not considered related to the study 
intervention. 
 
NOTE: An AE can therefore be any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use 
of study intervention. 
Events Meeting the AE Definition 
 
Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or other safety 
assessments (e.g., ECG, radiological scans, vital signs measurements), including those that worsen 
from baseline, considered clinically significant in the medical and scientific judgment of the 
investigator (and not related to progression of underlying disease [uveitis], unless judged by the 
investigator to be more severe than expected for the subject's condition). 
 
Exacerbation of a chronic or intermittent pre-existing condition including either an increase in 
frequency and/or intensity of the condition. 
 
New conditions detected or diagnosed after study intervention administration even though it may 
have been present before the start of the study. 
 
Signs, symptoms, or the clinical sequelae of a suspected drug-drug interaction. 
 
Signs, symptoms, or the clinical sequelae of a suspected overdose of either study intervention or a 
concomitant medication. Overdose per se will not be reported as an AE/SAE unless it is an 
intentional overdose taken with possible suicidal/self-harming intent. Such overdoses should be 
reported regardless of sequelae. 
 
“Lack of efficacy” or “failure of expected pharmacological action” per se will not be reported as an 
AE or SAE. Such instances will be captured in the efficacy assessments. However, the signs, 
symptoms, and/or clinical sequelae resulting from lack of efficacy will be reported as AE or SAE if 
they fulfil the definition of an AE or SAE.  
Events NOT Meeting the AE Definition  
 
Any clinically significant abnormal laboratory findings or other abnormal safety assessments which 
are associated with the underlying disease, unless judged by the investigator to be more severe than 
expected for the participant’s condition. 
 
The disease/disorder being studied or expected progression, signs, or symptoms of the 
disease/disorder being studied, unless more severe than expected for the participant’s condition. 
 
Medical or surgical procedure (e.g., endoscopy, appendectomy): the condition that leads to the 
procedure is the AE. 
 
Situations in which an untoward medical occurrence did not occur (social and/or convenience 
admission to a hospital). 
 
Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present or detected at 
the start of the study that do not worsen.

Table 11: 
Definition of SAE 
A SAE is defined as any untoward medical occurrence that, at any dose: 
1. Results in death 
2. Is life-threatening 
The term 'life-threatening' in the definition of 'serious' refers to an event in which the participant was at risk of 
death at the time of the event. It does not refer to an event, which hypothetically might have caused death, if it 
were more severe. 
3. Requires inpatient hospitalization or prolongation of existing hospitalization 
In general, hospitalization signifies that the participant has been detained (usually involving at least an overnight 
stay) at the hospital or emergency ward for observation and/or treatment that would not have been appropriate in 
the physician’s office or outpatient setting. Complications that occur during hospitalization are AEs. If a 
complication prolongs hospitalization or fulfills any other serious criteria, the event is serious. When in doubt as 
to whether “hospitalization” occurred or was necessary, the AE should be considered serious. 
Hospitalization for elective treatment of a pre-existing condition that did not worsen from baseline is not 
considered an AE. 
4. Results in persistent disability/incapacity 
 
The term disability means a substantial disruption of a person’s ability to conduct normal life functions. 
 
This definition is not intended to include experiences of relatively minor medical significance such as 
uncomplicated headache, nausea, vomiting, diarrhea, influenza, and accidental trauma (e.g., sprained ankle) 
which may interfere with or prevent everyday life functions but do not constitute a substantial disruption. 
5. Is a congenital anomaly/birth defect 
6. Other situations: 
 
Sight threatening event: A sight-threatening event is any event that places the subject at immediate risk of 
permanently losing vision in either eye as a direct result of the event.  
 
Ocular AEs required to be reported as SAEs: For the purposes of this study, the following ocular AEs will 
be reported as SAEs: 
 
Loss of 6 or more lines of vision (≥30 letters) from baseline 
 
Endophthalmitis (also to be reported as an ESI, Section 8.2.13) 
 
Purulent, infectious conjunctivitis 
 
Retinal detachment (also to be reported as an ESI, Section 8.2.13) 
 
IOP >35 mmHg that persists for at least 7 days despite pharmacologic therapy (also to be 
reported as an ESI, Section 8.2.13) 
 
Other significant ocular events per Investigator’s discretion 
 
Medical or scientific judgment should be exercised in deciding whether SAE reporting is appropriate in 
other situations such as important medical events that may not be immediately life-threatening or result in 
death or hospitalization but may jeopardize the participant or may require medical or surgical intervention to 
prevent one of the other outcomes listed in the above definition. These events should usually be considered 
serious. 
 
Examples of such events include invasive or malignant cancers, intensive treatment in an emergency room 
or at home for allergic bronchospasm, blood dyscrasias or convulsions that do not result in hospitalization, 
or development of drug dependency or drug abuse.

Table 12: 
Recording and Follow-Up of AE and/or SAE 
AE and SAE Recording 
 
When an AE/SAE occurs, it is the responsibility of the investigator to review all documentation 
(e.g., hospital progress notes, laboratory reports, and diagnostics reports) related to the event. 
 
The investigator will then record all relevant AE/SAE information in the CRF. 
 
It is not acceptable for the investigator to send photocopies of the participant’s medical records to 
Santen in lieu of completion of the Santen/AE/SAE CRF page. 
 
There may be instances when copies of medical records for certain cases are requested by Santen. 
In this case, all participant identifiers, with the exception of the participant number, will be 
redacted on the copies of the medical records before submission to Santen. 
 
The investigator will attempt to establish a diagnosis of the event based on signs, symptoms, 
and/or other clinical information. Whenever possible, the diagnosis (not the individual 
signs/symptoms) will be documented as the AE/SAE. 
Assessment of Intensity 
The investigator will assess intensity for each AE and SAE reported during the study and assign it to 1 
of the following categories:  
 
Mild: An event that is easily tolerated by the participant, causing minimal discomfort and not 
interfering with everyday activities. 
 
Moderate: An event that causes sufficient discomfort and interferes with normal everyday 
activities. 
 
Severe: An event that prevents normal everyday activities. An AE that is assessed as severe should 
not be confused with an SAE. Severe is a category utilized for rating the intensity of an event; and 
both AEs and SAEs can be assessed as severe. 
 
An event is defined as ‘serious’ when it meets at least 1 of the predefined outcomes as described in 
the definition of an SAE, NOT when it is rated as severe.

Table 12: 
Recording and Follow-Up of AE and/or SAE (Continued) 
AE and SAE Recording 
Assessment of Causality  Note: During the double-masked period, regardless of the source of the 
reported occurrence of an AE in a subject, the masked investigator will assess the causality of the AE. 
 
The investigator is obligated to assess the relationship between study intervention and each 
occurrence of each AE/SAE. 
 
A “reasonable possibility” of a relationship conveys that there are facts, evidence, and/or 
arguments to suggest a causal relationship, rather than a relationship cannot be ruled out. 
 
The following criterial can be used to make a causality judgment: 
 
Related (possibly or probably) 
o There is a clinically plausible time sequence between onset of the AE and 
investigational product administration/protocol procedure; and/or  
o There is a biologically plausible mechanism for investigational product causing or 
contributing to the AE; and 
o The AE may or may not be attributed to concurrent/underlying illness, other drugs, or 
protocol procedures. 
 
Not Related 
o A clinically plausible temporal sequence is inconsistent with the onset of the AE and 
Investigational product administration/protocol procedure; and/or 
o A causal relationship is considered biologically implausible. The investigator will use 
clinical judgment to determine the relationship. 
 
Alternative causes, such as underlying disease(s), concomitant therapy, and other risk factors, as 
well as the temporal relationship of the event to study intervention administration will be 
considered and investigated. 
 
The investigator will also consult the Investigational Brochure (IB) and/or Product Information, 
for marketed products, in his/her assessment. 
 
For each AE/SAE, the investigator must document in the medical records that he/she has reviewed 
the AE/SAE and has provided an assessment of causality. 
 
There may be situations in which an SAE has occurred, and the investigator has minimal 
information to include in the initial report to Santen. However, it is very important that the 
investigator always assess causality for every event before the initial transmission of the SAE 
data to Santen. 
 
The investigator may change his/her opinion of causality in light of follow-up information and 
send an SAE follow-up report with the updated causality assessment. 
 
The causality assessment is one of the criteria used when determining regulatory reporting 
requirements.

Table 12: 
Recording and Follow-Up of AE and/or SAE (Continued) 
AE and SAE Recording 
Procedures for Follow-up of AEs and SAEs 
 
The investigator is obligated to perform or arrange for the conduct of supplemental measurements 
and/or evaluations as medically indicated or as requested by Santen to elucidate the nature and/or 
causality of the AE or SAE as fully as possible. This may include additional laboratory tests or 
investigations, histopathological examinations, or consultation with other health care 
professionals. 
 
If a participant dies during participation in the study or during a recognized follow-up period, the 
investigator will provide Santen with a copy of any post--mortem findings including 
histopathology.  
 
New or updated information will be recorded in the originally completed CRF. 
 
The investigator will submit any updated SAE data to Santen within 24 hours of receipt of the 
information. 
Table 13: 
Reporting of SAEs 
SAE Reporting to Santen via an Electronic Data Collection Tool 
 
The primary mechanism for reporting an SAE to Santen will be the electronic data collection 
tool. 
 
If the electronic system is unavailable, then the site will use the paper SAE data collection tool 
(see next section) in order to report the event within 24 hours. 
 
The site will enter the SAE data into the electronic system as soon as it becomes available. 
 
After the study is completed at a given site, the electronic data collection tool will be taken off-
line to prevent the entry of new data or changes to existing data. 
 
If a site receives a report of a new SAE from a study participant or receives updated data on a 
previously reported SAE after the electronic data collection tool has been taken off-line, then the 
site can report this information on a paper SAE form (see next section) or to Santen Global 
Pharmacovigilance (Table 1). 
 
Contacts for SAE reporting can be found in Table 1. 
 
For SAE supporting information (i.e. X-ray reports, hospital summaries, etc.) that are not 
included in the EDC format, follow a procedure analogous to the manual SAE reporting process 
(see next section).  
SAE Reporting to Santen via Paper CRF (If Electronic Data Collection Tool is Unavailable) 
 
Complete both the paper AE and SAE Forms (located in your site regulatory binder) 
 
Attach a Fax Cover Sheet with your contact information and fax to Santen Global 
Pharmacovigilance (Table 1).  
 
In the rare circumstance of the absence of facsimile equipment, notification by telephone is 
acceptable with a copy of the paper AE and SAE forms sent by overnight mail or courier service. 
 
Initial notification via telephone does not replace the need for the investigator to complete and 
sign the SAE CRF pages within the designated reporting time frames. 
 
Contacts for SAE reporting can be found in Table 1.

Appendix 2: ETDRS Visual Acuity Chart Procedure 
Tumbling “E” chart is available for subjects who cannot read alphabet. 
12.2.1. 
Procedures for Refraction and Vision Testing 
Refraction and visual acuity measurements will be performed for all subjects by trained vision 
examiners only. The name and certification number of the vision examiner should be 
documented in the subject’s source document at each visit. When possible, visual acuity 
examiners should not have access to the subject’s chart or previous visual acuity testing results. 
Only the previous refraction should be made available. Refraction should be conducted prior to 
visual acuity testing to obtain best-corrected vision as described below. Best-corrected visual 
acuity is measured at all trial visits using standard charts, lighting, and procedures. Best 
correction is determined by careful refraction at that visit according to the standard protocol for 
refraction described below.   
12.2.1.1. Equipment 
Refraction equipment required includes:  
1. Retro illuminated light box and ETDRS 4-meter distance acuity chart set 
2. Trial lens frames 
3. Trial lens set with plus or minus cylinder lenses 
4. Jackson cross-cylinder of 0.25, 0.50, and 1.00 diopters 
5. Pinhole occluder 
6. Tissues or eye pads and tape 
7. A 1-meter rigid measuring stick 
12.2.1.2. Visual Acuity charts 
Chart 1 is used for testing the visual acuity of the RIGHT eye; Chart 2 for testing the LEFT eye; 
and Chart R (or 3) for refraction only. Subjects should not be allowed to see any of the charts 
before the examination. 
12.2.1.3. Visual Acuity Lane and Visual Acuity Box 
A distance of 4 meters is required between the subject’s eyes and the visual acuity charts. With 
the box light off, not more than 15 foot-candles of light (161.4 Lux) should fall on the center of 
the chart. To measure the amount of light, the room is set up for visual acuity testing, but with 
the box light off. The light meter is placed at the fourth line from the top of the chart, with its 
back against the chart and the reading is taken. If more than one lane is available for testing 
visual acuity, the visual acuity of individual subjects should be measured in the same lane at each 
visit, if possible. If different lanes are used to test visual acuity, they must each meet the same 
standards. 
Retro illuminated ETDRS charts are used in this trial. The illuminator box will be either wall-
mounted or mounted on the stand. The light box should be mounted at a height such that top of 
third row letter is 49±2 inches from floor.

The visual acuity light box is equipped with two General Electric 20-watt fluorescent tubes and 
ballast. Each tube is partly covered a 14-inch fenestrated sleeve, which is centered on the tube 
and open in the back. This serves as a “baffle” to produce even illumination over the testing 
chart. Because of the illumination of the fluorescent tube diminishes by 5 percent during the first 
100 hours and by another 5 percent during the next 2000 hours, new tubes should be kept on for 
4 days (96 hours) continuously, and should be replaced once a year. 
A sticker should be placed on the back of the light box, indicating the date on which the present 
tubes were installed. A spare set of burned in bulbs should be available on sight. 
12.2.1.4. Beginning Approximate Refraction 
At the baseline visit, the subject’s beginning refraction is determined by one of the following 
ways: 
a. If the subject’s visual acuity is 20/100 or better and the subject does not require 
glasses for distance vision, then the beginning approximate refraction should be no 
lens correction or plano. 
b. If the subject’s visual acuity is 20/100 or better and the subject requires glasses for 
distance viewing, the glasses should be measured using a lensometer, and these 
measurements are used for the beginning refraction. 
c. If the subject’s visual acuity is less than 20/100 with or without correction, then 
retinoscopy or auto-refraction should be performed to determine the beginning 
approximate refraction.  
d. If the subject wears contact lenses for refraction, a notation should be made that the 
refraction was over contact lenses. It is suggested that the subject wear the contact 
lenses for future examinations. If the subject is not a regular contact lens wearer and 
wore the lens by mistake, they should be removed, and you should wait at least 30 
minutes before beginning the refraction. The subject should be reminded not to wear 
contact lenses at subsequent visits. 
Refractions are performed with either plus or minus cylinder power. Whichever cylinder type is 
used at baseline (minus or plus) must be used for all subsequent visits. Best correction results 
should be recorded on Santen-provided worksheet which will be included in the source 
documents. At each follow-up visit, the results of the protocol refraction from the previous 
visits are used as the beginning approximate refraction. If the previous refraction is not 
available for some reason, the procedure described immediately above should be used. 
The charts used for measuring distance visual acuity must NOT be used for refraction.  
Refraction for each eye should be performed at 4 meters unless the subject’s visual acuity at 4 
meters on the refraction charts (Chart R or Chart 3) is worse than 20/160. If visual acuity is 
worse than 20/160 the eye is refracted at 1.0 meter. If during the refraction process at 1 meter, 
the subject is reading letters on the eighth line or lower line of the chart, the refraction should be 
continued at 4 meters. Whenever a subject cannot read any letters on the top line of Chart R or 
Chart 3 at 1.0 meter the vision should be checked with a pinhole to see whether reduced vision is 
due, at least in part, to a larger refractive error. If there is no improvement with the pinhole, then 
the eye is exempt from refraction.

12.2.1.5. Subjective Refraction 
Subjective refraction allows one to determine the best correction for a subject to perform the 
visual acuity tests.  The “push plus” approach is used. Add minus diopter spherical corrections 
only when the subject is able to read at least one more letter on a line or a letter on a smaller 
line.   
12.2.1.5.1. Procedure 
1. Measure and record the distance vision of the eye being tested using Chart R while 
occluding the fellow eye. The fellow eye should be lightly patched with an eye pad or 
tissue and tape. Subjects should be reminded to blink and encouraged to use eccentric 
fixation, or their side vision, when necessary. 
2. All refraction and vision testing must be done at 4 meters or 1 meter. Distance for 4 
meters is 13 feet and 1.5 inches or 157.5 inches. The one-meter distance is 39 and 3/8 
inches. 
3. All subjects should be seated for testing. A rigid measuring device should be used to 
measure the distance from the subject to the chart if testing is done at 1 meter. The 
distance is measured from the outer canthus to the center of the second letter (left eye) or 
fourth letter (right eye) of the third line of the chart. For 4-meter testing, clear and 
permanent floor markings should be used to mark the distance for consistency.   
4. Place and adjust the trial frame on the subject’s face so that the lens cells are parallel to 
the anterior plane of the orbits and centered in front of the pupils. Adjust the lens cells for 
the proper distance from the cornea. Be sure the trial frame is comfortable on the 
subject’s face.   
5. Occlude the left eye by lightly patching with the eye pad or tissue and tape.   
a. Place the spherical lens correction in the compartment closest to the eye. 
b. The cylindrical lens correction, if present, is placed in the compartment in front of 
the spherical correction.  Adjust the axis. 
6. Spherical Correction: To determine the highest plus or least minus sphere, refract the 
right eye. The following refraction steps are recommended for visual acuities of 
20/10 to 20/80 with the beginning approximate refraction. For visual acuities less 
than 20/80, refer to the refraction table for the appropriate sphere and cylinder 
powers and testing distance and follow a similar procedure.  Note: Whenever visual 
acuity is improved to a higher range, refraction should be performed with the smaller 
sphere and cylinder powers given for the better visual acuity level.   
a. Hold a +0.50 sphere in front of the subject’s right eye. The subject should be looking 
at the smallest legible line on the visual acuity chart. In these exact words, ask the 
subject, “Is this better, worse, or no change?” 
b. If the subject responds that the vision is worse or blurred, remove the +0.50 sphere 
from in front of the trial frame and go to Step 6d. 
c. If the subject responds better or no change, remove the +0.50 sphere from in front of 
the trial frame and replace the spherical lens in the trial frame with a spherical lens 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution

Page 110 of 133 
that is one-half diopter more positive. Continue this procedure by returning to Step 6a 
and repeating this process until a +0.50 makes the vision worse or blurred and then 
go to Step 6d.   
d. Hold a -0.50 sphere in front of the subject’s right eye. In these exact words, ask the 
subject, “Is this better, worse, or no change?” If the subject replies “worse” or “no 
change,” go to Step 6f. If they reply “better” go to step 6e. 
e. Hold the -0.50 sphere in front of the eye. If the subject responds that the vision is 
better, ask the subject to read the visual acuity chart. Only when the visual acuity is 
improved, by at least one letter, may you increase the minus by 0.50 (or decrease 
the plus) and repeat Step 6d. Whenever visual acuity is not improved, go to Step 6f.   
f. Remove the -0.50 sphere from in front of the eye and hold a +0.50 sphere in front of 
the right eye. In these exact words, ask the subject, “Is this better, worse, or no 
change?” If the subject responds that the vision is better or unchanged, then return to 
Step 6c. Otherwise, go to Step 7. Spherical testing should always end with a plus 
lens.   
7. Cylinder Axis: To determine and refine the cylinder axis for PLUS cylinder, proceed as 
follows; (if minus cylinders are used, the appropriate technique using minus cylinders 
must be employed and minus cylinder must be used throughout the trial.) 
a. Have the subject look at a line which is either one or two lines larger than the 
smallest line the subject is able to read.  Ask the subject to focus on a rounded 
letter such as, “C”, “D”, or “O”.  The subject should focus on the same letter 
throughout this procedure.   
b. If a cylinder is present in the beginning approximate refraction, then go to Step 
7c.  Otherwise, follow the option listed below to determine if cylinder may be 
needed.   
Testing for cylinder when there is none in the beginning approximate 
refraction: 
Place a +0.50 diopter cylinder with a positive axis first at 90°, then compare this 
to no cylinder; repeat this procedure for 180°, then 45°, and 135° always 
comparing to no cylinder after each axis position.  If the subject says that the 
vision is improved at any one of the four axis positions, place a +0.50 cylindrical 
lens in the trial frame at the preferred axis and go to Step 7c.  If the subject prefers 
no cylinder at all four axis positions, then go to Step 9. 
c. Place the +0.25 diopter hand held cross-cylinder (for VA 20/10 – 20/80) first with 
the positive axis 45° to the right of the preferred cylinder axis (as determined 
above), and second with the positive axis 45° to the left of the preferred cylinder 
axis.  Ask the subject, “Which do you like better, position one or position two?”  
Also, tell the subject that both positions may blur their vision.  The subject must 
choose the least blurred position, either one or two.  “Neither” is allowed only if 
both positions are equally blurred or equally good.

d. If “neither” position is better, and this was the first test of axis position, move the 
axis of the cylinder in the trial frame 15° to the right or left and return to Step 7c.  
Otherwise, proceed to Step 7e.   
e. When one position is preferred over another, move the cylinder to the preferred 
positive axis position in the step sizes noted below and return to Step 7c.  If no 
single position is better than another, then go to Step 8.

8. Cylinder Power: Cylinder power is refined by following the step: 
a. Ask the subject to look at the smallest line that can be read on the visual acuity chart.   
b. Test the cylinder power by placing 0.25 diopter cross-cylinder (for vision of 20/10 – 
20/80) first with the positive axis and second with the negative axis coincident with 
the cylinder axis. Ask the subject, “Which is better, position one or position two?” Do 
not give the subject the choice of neither. 
c. If the subject prefers the minus axis coincident with the cylinder axis, the total power 
of the correcting plus cylinder is reduced by 0.25 diopter. Repeat the process until the 
subject cannot choose one of the cross-cylinder positions over the other. If the subject 
indicates a change that would introduce negative cylinder power, remove all cylinder 
power and continue testing for positive cylinder power at an axis 90° away from the 
previous axis. Otherwise, go to Step 8d.   
d. If the subject prefers the plus axis coincident with the cylinder axis, increase the 
power of the cylinder by 0.25 diopter and return to Step 8b. Otherwise, proceed to 
Step 8e. 
e. When the subject feels that both positions are equally bad or good, and the cylinder 
power in the trial frame has changed by more than 0.50 diopter, return to Step 7c and 
re-check the axis if necessary. Otherwise, proceed to Step 9. 
Note: If the cylinder is changed by more than 0.50 diopter, the spherical equivalent 
should be maintained. (For each 0.50 plus CX increase, add -0.25 to the sphere, for 
each 0.50 minus CX increase, add +0.25 to the sphere). 
9. Spherical Correction Refinement: Recheck, or “refine” the power of the sphere by 
adding +0.25 and -0.25 spheres and changing the spherical power by 0.25 diopter 
increments of the appropriate sign until the subject cannot detect any improvement in 
vision. As a reminder, minus sphere should only be added if the subject can read 
additional letters and spherical testing should always begin and end with a plus lens.

10. Record the lens corrections obtained by subjective refraction for the right eye on the 
examination form in the section for visual acuity measurements as the correction obtained 
by protocol refraction for the right eye. 
11. Repeat the entire process (Steps 1-10) for the left eye and record the refraction results on 
the VAE worksheet. 
12.2.1.6. Best-Corrected Visual Acuity Measures 
1. As a reminder, Charts 1, 2, and R (or 3) are used for testing the right eye, left eye, and 
refraction, respectively. Subjects should not see the charts until the test begins. 
2. The lens correction from the subjective refraction should be in the trial frame worn by the 
subject.   
3. All eyes must be tested at 4 meters first, even if the refraction was performed at 1 
meter. 
4. The subject should be seated comfortably directly in front of the chart so that the eyes 
remain at the 4 meter distance. Testing always begins with the right eye. The fellow eye 
should be occluded with a folded tissue or eye pad lightly taped over the eye behind the 
trial frame serves as an effective occlude that allows eccentric fixation without 
inadvertent use of the covered eye. After testing the right eye, occlusion of the right eye 
should be done BEFORE Chart 2 is put up for testing the left eye.   
5. The subject is asked to read the letters slowly, approximately one letter per second. The 
subject should be told that only one chance is given to read each letter, but may change 
their mind before moving to the next letter. If the subject is unsure about the identity of 
the letter, then the subject should be encouraged to guess.   
6. The subject should begin by reading the top line of the chart and continue reading 
every letter on each smaller line, from left to right on each line. The subject should 
be encouraged to continue reading even if making mistakes. Each letter read is 
counted. The examiner circles every correct letter read and totals each line and the whole 
column (0 if no letters are correct) on the data collection form. An X is put through letters 
read incorrectly. Letters, for which no guess was attempted, are not marked. When a 
subject reaches a level where he/she cannot guess, the examiner may stop the test 
provided that the subject has made errors on previous guesses, which is a clear indication 
that the best visual acuity has been obtained. 
7. When a subject cannot read at least 20 letters on the chart at 4.0 meters, the subject 
is tested at 1.0 meter. The distance from the subject to the chart should be measured 
again using the rigid one meter stick. The distance is measured from the outer canthus 
to the center of the fourth letter (right eye) or the second letter (left eye) of the third 
line of the chart. The spherical correction in the trial frame should be changed by 
adding +0.75 to correct for the closer test distance. The subject may fixate eccentrically 
or turn or shake his/her head to improve visual acuity. Particular care should be taken to 
make sure the subject does not move forward when testing at 1 meter. The subject should 
be reminded to blink.

Page 113 of 133 
8. The examiner should not tell the subject if a letter was identified correctly. The subject 
may be encouraged by neutral comments, such as “good”, “next”, and “OK.” 
9. The examiner should not stand close to the chart during testing. Attention should be 
focused on the subject and data collection form. If the subject has difficulty locating the 
next line to read, the examiner may go up to the chart and point briefly to the next line to 
be read, but then must move away from the chart. 
10. When 20 or more letters are read at 4 meters the visual acuity score for that eye is 
recorded as the number of letters correct at 4 meters plus 30. The subject gets credit 
for the thirty 1 meter letters even though they did not have to read them. Otherwise, the 
visual acuity score is the number of letters read correctly at 1.0 meter plus the number, if 
any, read at 4 meters. If no letters are read correctly at either 4 meters or 1 meter, then the 
visual acuity score is recorded as 0.   
12.2.1.7. Testing for Count Finger Vision, Hand Motion Vision and Light Perception/No 
Light Perception Vision 
If the subject’s visual acuity is so poor that he/she cannot read any chart letters when tested at 
one meter then the subject’s ability to count fingers, detect hand motion, or have light perception 
should be evaluated. 
12.2.1.7.1. Testing for Count Fingers Vision 
In testing for count fingers vision, the examiner’s hand holding 1, 2, or 5 fingers is held steady at 
a distance of two feet directly in front of the eye being examined. The fellow eye is completely 
occluded with a patch on the face. A light should be shone directly on the hand from behind the 
subject. The examiner’s fingers should be presented in random order and repeated five times.  
Eccentric fixation, if present, should be encouraged. If the subject correctly identifies three of the 
five presentations, then count fingers vision is noted. If not, then the subject must be tested for 
hand motion vision.   
12.2.1.7.2. Testing for Hand Motion Vision 
The examiner’s hand with all fingers spread out should be extended two feet directly in front of 
the eye being examined. The fellow eye should be occluded with a patch on the subject’s face.  A 
light should be shown directly on the examiner’s hand from behind the subject. The examiner’s 
hand should be moved in an up-and-down direction (vertically) or in a side-to-side direction 
(horizontally) at a constant speed of approximately one back and forth presentation per second. 
The subject is instructed that the examiner’s hand will be presented, and they will have to 
respond to the question: “What am I doing with my hand?” This should be repeated five times. 
Three out of five correct responses indicate that hand motion vision is present. If the subject does 
not correctly identify three of five presentations, then you must test for light perception. 
12.2.1.7.3. Testing for Light Perception/No Light Perception Vision 
Light perception should be tested with an indirect ophthalmoscope in a darkened room. The 
fellow eye should be completely patched and covered by the subject’s hand. The indirect 
ophthalmoscope light should be in focus at 1 meter with the rheostat set at maximum voltage. 
From that distance the beam should be directed in and out of the subject’s eye at least four times, 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 114 of 133 
and the subject should be asked to respond when he/she sees the light. If the examiner is 
convinced that the subject perceives the light, vision should be recorded as “light perception,” if 
not, vision should be recorded as “no light perception.”

Appendix 3: Adverse Event Case Report Form Items and Terms 
Concise Description of Event: 
A concise description of the signs, symptoms, complaints, or 
diagnosis of the subject’s problem (e.g., nasal congestion). Complete 
one AE form for related symptoms that can be grouped as one 
condition (e.g., If a subject complains of sneezing, nasal congestion, 
watery eyes, the AE is described as cold symptoms). If two 
independent events occur at the same time, separate AE forms must 
be completed for each event. 
Affected Eye(s): 
Indicate if ocular event is OD, OS, or OU. Non-ocular events should 
be recorded as N/A. 
Adverse Event Serious?: 
If AE is serious or an Event of Special Interest, Santen must be 
notified immediately (within 24 hours). Complete both the AE and 
the SAE eCRFs in the EDC system. In the event the EDC system is 
unavailable, and your site needs to report an SAE, please follow the 
manual process described in the body of the protocol under 
“Reporting of SAEs.”   
Date of Event Onset: 
The date the event started. 
Maximum Severity of Event: 
Record the severity of the AE according to the following definitions: 
Mild: Aware or unaware of event, but easily tolerated 
Moderate: Discomfort enough to cause interference with usual 
activity 
Severe: Incapacitating; unable to work or perform usual activity 
For intermittent events, record the maximum severity of the 
individual events. For example, if a subject complains of intermittent 
headaches for one week and the severity of each headache ranges 
from mild to moderate, then the severity would be moderate. Record 
that the severity of the headaches ranged from mild to moderate in 
the comment section of the form.  
If an event occurs with each injection (e.g., eyes burn mild to 
moderate for 5 minutes after every injection), record the maximum 
severity of the individual incident. In the example above, the severity 
is moderate. Record that the severity of the event ranged from mild 
to moderate in the comment section of the form.  
Action Taken as Related to 
this AE:  
Indicate the action taken as a result of the AE. If the frequency of 
Investigational product administration was changed or discontinued 
temporarily or if surgery was required, provide more detailed 
explanation in the comment section of the form. If “Other” is 
indicated, specify the action taken. 

Protocol 010906IN, LUMINA 
DE-109 Injection Solution 
14JUL2021 
Confidential 
Page 116 of 133 
Outcome of Event: 
Indicate the outcome of the AE and provide resolution date or date 
of death.   
For intermittent events (e.g., intermittent headache) and events that 
occur with each injection (e.g., eyes burn for 5 minutes after every 
injection), the date should reflect when the last occurrence resolved 
or stopped. For example, if a subject has an intermittent headache 
from 12/14/2010 until 12/21/2010 and each individual headache lasts 
3 hours a day, then the date of resolution is 12/21/2010 (NOT 
12/14/2010). 
If treatment was initiated, then include the treatment and duration in 
the comments section (e.g., subject took acetaminophen for 
headache on 12/14/2010, 12/17/2010 and 12/20/2010). 
Relationship to Study 
Drug/Investigational 
Product: 
Indicate if there is a reasonable possibility that the AE may have 
been caused by the study drug/investigational product with a Yes or 
No response. A “reasonable possibility” means there is evidence to 
suggest a causal relationship between the study drug/investigational 
product and the AE.  
If response is No, select the possible alternative explanation of the 
event from the list provided. 
Relationship to Injection 
Procedure: 
The event cannot be attributed to the subject’s underlying medical 
condition or other concomitant therapy and there is a compelling 
temporal relationship between the onset of the event and the 
injection procedure that leads the investigator to believe there is 
evidence of a reasonable causal relationship. 
 
For SAE supporting information (i.e., X-ray reports, hospital summaries, etc.) that are not 
included in the EDC format, follow the same reporting process as for manual SAE reporting.

aVH 0 response (resolution of inflammation) is defined as a VH score of 0 in the study eye 
at a specified follow up visit based on the modified SUN scale.  
b  VH 0 or 2-unit response is defined as having a VH score of 0 or a decrease 
(improvement) of at least 2 units (i.e., 2+ to 0, 3+ to 1+, or 4+ to 2+) from baseline in the 
study eye in VH score at a specified follow up visit based on the modified SUN scale.   
c VH 0 or 0.5+ response (remission of inflammation) is defined as a VH score of 0 or 
0.5+ in the study eye at a specified follow-up visit based on the modified SUN scale.  
d Corticosteroid tapering success with resolution is defined as achievement of a 
prednisone-equivalent oral dose of 0 mg/day and a VH score of 0 in the study eye at a 
specified follow-up visit. This endpoint is assessed based on the Intent-to-Taper 
population (study eyes of subjects who received systemic [oral] corticosteroids at a

Table 2: Study Objectives, Estimands, and Endpoints 
Study Objectives and Estimands 
Primary objective (efficacy vs. sham): The primary objective of this study 
is to evaluate the efficacy of intravitreal injection of 440 μg DE-109 every 
2 months as compared with sham for the treatment of active, 
non-infectious uveitis of the posterior segment of the eye. 
Primary estimand: Vitreous haze 0 (VH0) response rate in DE-109 440 
µg group vs. Sham group at Month 5 in all study eyes that received at 
least one dose of the study treatment where all eyes that were rescued due 
to worsening of uveitis or discontinued from the study due to lack of 
efficacy or due to adverse event before Month 5 will be treated as non-
responders. For study eyes that were rescued for any other reasons or 
had missing data due to other reasons, imputation by the multiple 
imputation-based approach will be used.  
Treatment policy estimand: VH0 response rate in DE-109 440 µg group 
vs. Sham group at Month 5 in all study eyes that received at least one

dose of the study treatment regardless of whether subjects have received 
rescue therapy or discontinued from the study due to lack of efficacy or 
due to adverse event. For study eyes that had missing data due to any 
reason, imputation by the multiple imputation-based approach will be 
used. 
Composite estimand: Mean composite score in DE-109 440 µg group vs. 
Sham group at Month 3 and at Month 5 in all study eyes that received at 
least one dose of study treatment. Each study eye will be assigned one of 
the following scores: 
 Score = 3 if a study eye achieved VH score of 0 at the specified 
visit without taking any rescue therapies that could affect VH 
score prior to the specified visit  
 Score = 2 if a study eye had at least improved by 2 units in VH 
(compared to baseline) at the specified visit without taking any 
rescue therapies that could affect VH score prior to the specified 
visit   
 Score = 1 if a study eye achieved VH score of 0.5+ at the specified 
visit without taking any rescue therapies that could affect VH 
score prior to the specified visit   
 Score = -1 if a study eye got rescued due to worsening of uveitis or 
discontinued from the study due to lack of efficacy or due to 
adverse event prior to the specified visit  
 Score = 0 if otherwise

in the study eye at a specified follow up visit based on the modified SUN 
scale. 
b  Refer to composite score scales defined in the composite estimand in 
this table.  
cb VH 0 or 2-unit response is defined as having a VH score of 0 or a

(i.e., 2+ to 0, 3+ to 1+, or 4+ to 2+) from baseline in the study eye in VH 
score at a specified follow up visit based on the modified SUN scale.   
dc VH 0 or 0.5+ response (remission of inflammation) is defined as a VH 
score of 0 or 0.5+ in the study eye at a specified follow-up visit based on 
the modified SUN scale.  
ed Corticosteroid tapering success with resolution is defined as 
achievement of a prednisone-equivalent oral dose of 0 mg/day and a VH 
score of 0 in the study eye at a specified follow-up visit. This endpoint is 
assessed based on the Intent-to-Taper population (study eyes of subjects 
who received systemic [oral] corticosteroids at a stable prednisone-
equivalent dose between ≥15 mg/day and ≤40 mg/day that has remained 
stable for at least 1 week  
[7 days] prior to and including on Day 1). 
fe BCVA 3-line response is defined as an increase (improvement) of at least

up visit. This endpoint is assessed based on eyes with a baseline best-
corrected visual acuity (BCVA) ≤ 70 ETDRS letters (Snellen equivalent 
of 20/40 or worse). 
Rationale: 
This change is in accordance with the ICH E9 (R1) addendum, to define 
the primary estimand and other estimands of the study. Key secondary

Interim Analyses, Primary Analysis, and Analysis of Open-Label 
Period: 
An interim analysis is planned when the first 100 subjects complete their 
Month 5 Visit.  There are two goals for this interim analysis (1) to assess 
for futility; and (2) to re-assess the sample size. Alpha spending for this 
interim analysis will be 0.00001. Sample size re-assessment will be 
performed with the “promising zone” approach as follows (Mehta et al., 
2011). If the conditional power at the interim analysis is between 50% and 
80%, the suggested sample size increase would be 100 subjects (i.e., 50% 
of the original sample size). If, on the other hand, the conditional power is 
> 80% or < 50%, no change to the sample size will take place. If the 
conditional power is <10%, then the Data Monitoring Committee (DMC) 
would recommend stopping the trial due to futility.  The DMC could 
recommend stopping the trial due to safety concerns at any of the DMC 
meetings and the interim analysis. An independent statistical and 
programming team will be used to perform this interim analysis of 
unmasked data and the DMC will review the results and make 
recommendations based on the findings. The planned interim analysis will

Vision 20/40 or Worse: 
 The ITT population will consist of all study eyes. The ITT 
population will be the analysis population for the primary 
analysis and will use treatment as randomized.  
 For analyses of ocular AEs and safety parameters assessed per 
eye, the Safety population will consist of all study eyes which 
received at least one administration of IP. For analyses of non-
ocular AEs and safety parameters assessed per subject, the 
Safety population will consist of all subjects who received at 
least one administration of IP.

randomized and received at least one administration of study 
treatment. The ITT FAS population will be the analysis 
population for the primary analysis and will use treatment as 
randomized.  
Rationale:

 Subjects who (a) receive rescue therapy for conditions other 
than worsening of uveitis or (b) are rescued due to the

forward (LOCF) approach.   
The response status will then be determined based on the observed or 
imputed VH scores. Sensitivity analyses using other imputation methods 
will be performed. 
For medical events including AEs, completely or partially missing onset 
and resolution dates will be imputed in a conservative fashion to be 
detailed in the SAP.  The same rules will be followed to impute completely 
or partially missing start and end dates of non-study medications. 
Unless specified otherwise, descriptive summaries will be based on

No imputation is needed for composite score analysis as eyes with 
missing VH scores will be assigned a score of zero, unless they are

Statistical Analysis Methods 
For the primary analysis of VH 0 response at Month 5, the Cochran-Mantel-
Haenszel (CMH) test with Row Mean Scores statistic stratified by number of 
enrolled eyes from a subject (one eye or two eyes) and region (US or non-US) 
will be conducted. Logistic generalized estimating equation (GEE) model will be 
used as a sensitivity analysis. 
A hierarchical approach will be used to control the overall Type I error rate 
associated with the multiple comparisons across the primary and the key 
secondary efficacy endpoints at the 0.04999 level (two-sided) .  
If the hypothesis testing for the primary endpoint successfully rejects the null 
hypothesis, the first key secondary efficacy endpoint will be tested, and so on.  
For the other secondary endpoints, no multiplicity adjustment will be made. 
For secondary efficacy endpoints during double-masked period: 
All binary secondary endpoints will be analyzed using the Cochran-Mantel-
Haenszel (CMH) test with Row Mean Scores statistic stratified by number of 
enrolled eyes from a subject (one eye or two eyes) and region (US vs. non-US). 
Change-from-baseline endpoints will be analyzed by a mixed-effects model for 
repeated measures (MMRM) using observed cases. The statistical model for the 
analysis of each continuous secondary endpoint may be adjusted if it fails to 
converge. More details regarding model specifications will be provided in the 
SAP.

population (study eyes of subjects who received systemic [oral] corticosteroids at a 
stable prednisone-equivalent dose of between ≥15 mg/day and ≤40 mg/day that has 
remained stable for at least 1 week [7 days] prior to and including on Day 1). 
e BCVA 3-line response is defined as an increase (improvement) of at least 3 lines (15 
ETDRS letters) from baseline in BCVA at a specified follow-up visit. This endpoint is 
assessed based on eyes with a baseline best-corrected visual acuity (BCVA) ≤ 70 ETDRS 
letters (Snellen equivalent of 20/40 or worse).

Statistical Analysis  
For the primary analysis of VH 0 response at Month 5, the Cochran-Mantel-
Haenszel (CMH) test with Row Mean Scores statistic stratified by number of 
enrolled eyes from a subject (one eye or two eyes), baseline systemic (oral) 
corticosteroid use (yes or no), and region (US or non-US) will be conducted.  
Logistic generalized estimating equation (GEE) model, treatment policy strategy, 
last-observation-carried-forward (LOCF) imputation, and multiple imputation 
with tipping point analysis will be used as a sensitivity analysis. 
A hierarchical approach will be used to control the overall Type I error rate 
associated with the multiple comparisons across the primary and the key 
secondary efficacy endpoints at the 0.04999 level (two-sided).  
If the hypothesis testing for the primary endpoint successfully rejects the null 
hypothesis, the first key secondary efficacy endpoint will be tested, and so on.  
All the other secondary efficacy endpoints are supportive in nature. Therefore, 
no formal hypothesis testing will be performed on secondary efficacy endpoints. 
Two-sided 95% confidence intervals and nominal p-values may be reported for 
them, and such results will be interpreted descriptively in terms of the support 
they provide to the treatment comparisons for the primary and the key 
secondary efficacy endpoints in the sense of logical consistency. For the other 
secondary endpoints, no multiplicity adjustment will be made. 
For secondary efficacy endpoints during double-masked period: 
All binary secondary endpoints will be analyzed using the Cochran-Mantel-
Haenszel (CMH) test with Row Mean Scores statistic stratified by number of 
enrolled eyes from a subject (one eye or two eyes), baseline systemic (oral) 
corticosteroid use (yes or no), and region (US vs. non-US). Change-from-

baseline endpoints will be analyzed by a mixed-effects model for repeated 
measures (MMRM) using observed cases. The statistical model for the analysis of 
each continuous secondary endpoint may be adjusted if it fails to converge. More 
details regarding model specifications will be provided in the SAP. 
 
Footnotes: 
Note: Vitreous haze (VH) will be scored using the modified Standardized Uveitis 
Nomenclature (SUN) scale.  
a VH 0 response (resolution of inflammation) is defined as a VH score of 0 in the 
study eye at a specified follow up visit based on the modified SUN scale. 
b  Refer to composite score scales defined in the composite estimand in this 
table.   
cb VH 0 or 2-unit response is defined as having a VH score of 0 or a decrease 
(improvement) of at least 2 units  
(i.e., 2+ to 0, 3+ to 1+, or 4+ to 2+) from baseline in the study eye in VH score 
at a specified follow up visit based on the modified SUN scale.   
dc VH 0 or 0.5+ response (remission of inflammation) is defined as a VH score of 
0 or 0.5+ in the study eye at a specified follow-up visit based on the modified 
SUN scale.  
ed Corticosteroid tapering success with resolution is defined as achievement of a 
prednisone-equivalent oral dose of 0 mg/day and a VH score of 0 in the study 
eye at a specified follow-up visit. This endpoint is assessed based on the Intent-
to-Taper population (study eyes of subjects who received systemic [oral] 
corticosteroids at a stable prednisone-equivalent of dose between ≥15 mg/day 
and ≤40 mg/day that has remained stable for at least 1 week  
[7 days] prior to and including on Day 1). 
fe BCVA 3-line response is defined as an increase (improvement) of at least 3 
lines (15 ETDRS letters) from baseline in BCVA at a specified follow-up visit. 
This endpoint is assessed based on eyes with a baseline best-corrected visual 
acuity (BCVA) ≤ 70 ETDRS letters (Snellen equivalent of 20/40 or worse). 
Rationale: 
Added the clarification in the analysis of the primary endpoint regarding 
the stratification factors. Sensitivity analysis strategy is changed to be 
aligned with the study estimands. Clarification on the multiplicity 
adjustment for other secondary endpoints is also added.
