PROTOCOL SUMMARY 
 
 
Title: 
A Single Arm Open-Label Study to Evaluate the Therapeutic Effects and Safety 
of a 6-Week Treatment Regimen of ALK4290 in Patients with Refractory Wet 
Age-Related Macular Degeneration (wAMD) 
 
Précis:  
This study is designed to evaluate the therapeutic effects and safety of oral 
ALK4290 administered at 800 mg daily over a 6-week dosing period in subjects 
with refractory wAMD following treatment with intravitreal (IVT) anti-vascular 
endothelial growth factor (anti-VEGF).  The study agent will be self-
administered orally.  Training on study agent administration will be conducted 
prior to initial study agent administration (at Visit 2) under the supervision of 
study personnel.  All study agent administrations at the study site will be done 
under the direct supervision of the study personnel for documentation of precise 
administration times.    
 
All subjects will undergo a screening visit, baseline/treatment visit(s), an end of 
study/early termination visit, and follow-up visits, as applicable. Visits will 
include safety and tolerability assessments, best corrected visual acuity (BCVA) 
as measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) 
testing method, and morphological evaluations utilizing spectral domain optical 
coherence tomography (SD-OCT) and fundus photography/fluorescein 
angiography (FA).  For a complete listing of study events, please see Section 
15.1, Schedule of Events Table.  
 
Objectives: 
The primary objective of the study is to investigate the potential therapeutic 
effects of a 6-week, twice daily oral dosing regimen of ALK4290 on BCVA, as 
measured by ETDRS, in subjects with refractory wAMD following treatment 
with IVT anti-VEGF.  As a secondary objective, the study will assess the safety 
of the proposed dosing regimen.  The exploratory objectives are to investigate 
the potential pharmacokinetic and ocular morphological effects related to twice 
daily treatment of ALK4290 in refractory subjects with wAMD by measuring 
changes in concentrations of ALK4290 in plasma at various time points as well 
as central subfield thickness (CST), intraretinal fluid (IRF), subretinal fluid 
(SRF), and pigment epithelial detachment (PED) identified by SD-OCT and 
fundus photography/FA. Additionally, pharmacogenomic and biomarker 
evaluations will be conducted on blood and plasma samples. 
 
Endpoints: 
Primary Endpoint:  
• 
Mean change in BCVA letter score as measured by the ETDRS testing 
method 
 
Secondary Endpoint:  
• 
Safety as assessed by incidence, seriousness, and severity of adverse 
events

INTRODUCTION 
2.1 
BACKGROUND INFORMATION 
Age-related macular degeneration (AMD) is the most common degenerative disease of the macula and the leading 
cause of irreversible blindness in the industrialized world in adults over 50, with a global prevalence of 170 million 
(Pennington 2016, Wong 2014).  It is estimated that 196 million people worldwide will have AMD in 2020, increasing 
to 288 million in 2040 (Wong 2014).  Approximately 10% of individuals aged 65 to 74 years and 30% of individuals 
aged 75 to 85 years show signs of AMD (Friedman 2004).   
Early stage AMD, also termed age-related maculopathy (ARM), is associated with the accumulation of drusen and 
disturbances of the retinal pigment epithelium (RPE) (van Leeuwen 2003).  Drusen are biochemical by-products of 
photoreceptor cells that accumulate in the Bruch’s membrane and are categorized based on their visual appearance 
(Bird 2010). Morphology, number, and location of drusen relative to the macula are indicative of disease progression 
(Jager 2008, van Leeuwen 2003).  Epidemiological studies suggest that oxidative stress is associated with both the 
incidence and the progression of AMD.  Growing evidence indicates that AMD is downstream of a chronic 
inflammatory condition wherein activation of the immune system plays an important role (Buschini 2015).  Metabolic 
products accumulate in the extracellular space between Bruch’s membrane and the RPE, activating the complement 
system with a significant increase in oxidative stress, similar to what happens in atherosclerosis or Alzheimer’s disease 
(Buschini 2015). 
Clinically, advanced AMD is categorized into the non-exudative dry or atrophic form and the exudative wet or 
neovascular form.  Advanced dry AMD is characterized by drusen and geographic atrophy extending to the center of 
the macula (Jager 2008).  Exudative or wet AMD (wAMD), arises from the growth of abnormal blood vessels from the 
choroid into the normally avascular sub-RPE and subretinal regions (choroidal neovascularization (CNV). Fluid 
accumulation in the sub-RPE spaces, derived from the abnormal choriocapillaris changes and growth under the RPE or 
retina causing serum and blood accumulation into subretinal spaces, leads to retinal thickening, mostly at the macular 
area.  Involvement of the fovea by choroidal neovascular membrane (CNVM) growth, edema, and hemorrhage may 
profoundly impair visual acuity (VA) and loss of vision can be precipitous (Pennington 2016, Jager 2008).  In the

presence of active CNV, patients may also experience pigment epithelial detachment (PED), a pathological process in 
which the retinal pigment epithelium separates from the underlying Bruch’s membrane due to the presence of blood, 
SRF and/or IRF (Pepple 2011).  PEDs are important markers of disease severity, risk for progression, and vision loss, 
and are seen in up to 62% of eyes with advanced wAMD (Coscas 2007).  Although wAMD represents only 10 to 15% 
of the overall prevalence of age-related macular AMD, it is responsible for more than 80% of cases of severe visual 
loss or legal blindness resulting from AMD (Ferris 1984). 
Currently, blockade of vascular endothelial growth factor, a potent proangiogenic messenger, is the basis of available 
therapies for wAMD (Riaz 2017, Ambati 2012).  Intravitreally administered anti-VEGF therapies include Lucentis® 
(ranibizumab)(Brown 2006, Rosenfeld 2006), Avastin® (bevacizumab)(Martin 2011)(typically used as an off-label 
drug to treat wAMD), and Eylea® (aflibercept) (Heier 2012).  These agents have become the standard of care, and have 
led to significant improvements in lesion morphology, reduction of the vascular leakage, and, as a consequence, 
improvement in central vision.   
Although anti-VEGF agents are a key foundation in wAMD treatment, some patients have a poor response or a 
nonresponse to IVT anti-VEGF therapy.  In these patients, persistent fluid remains or recurs following treatment.  In 
the randomized Comparison of Age-Related Macular Degeneration Treatments Trials (CATT), investigators assessed 
the efficacy of IVT Lucentis® or Avastin® in both monthly and in as-needed regimens (Martin 2012).  Despite monthly 
treatments with these anti-VEGF agents for 2 years, 51.5% of patients receiving Lucentis®, and 67.4% of patients 
treated with Avastin®, had evidence of persistent fluid on OCT.  A similar study of IVT administration of Eylea® 
reported that 19.7–36.6% of patients had active exudation on either FA or OCT after 1 year of regular therapy (given 
monthly or every 2 months) (Heier 2012).   
Researchers have used various terms to describe these patients including “incomplete responders,” “poor responders,” 
“nonresponders,” “unresponsive,” “treatment resistant,” “refractory,” etc.  We have chosen the term, “refractory” to 
describe and classify the group of patients with persistent SRF, IRF, and absence of improvement in visual acuity after 
at least 3 consecutive (approximately 4-6 weeks apart) IVT anti-VEGF injections.  A clear unmet medical need exists 
to provide an appropriate therapeutic option for this subset of patients.  Therefore, to address this clinical need, the oral 
therapeutic ALK4290 was developed. 
2.2 
RATIONALE 
 
Alkahest study ALK4290-202 will evaluate 400 mg of ALK4290 administered orally twice a day for a total daily dose 
of 800 mg.  ALK4290 is a highly specific and potent small molecule antagonist of the human C-C chemokine receptor 
type 3 (CCR3). The CCR3/eotaxin axis is a key chemotactic factor for eosinophils, mast cells, and, in the context of 
wAMD, endothelial cells. Inhibiting CCR3 interrupts endothelial cell migration, thereby reducing the morphological 
changes (e.g., central retinal thickness (CRT), edema, and blood leakage) attributed to pathologic CNV (Nagai 2015). 
The anticipated clinical results from an orally administered CCR3 antagonist therapy would be to maintain or, 
potentially, improve visual acuity, enhance quality of life, and provide a clinical option for patients who are refractory 
to IVT anti-VEGF therapy. 
 
Although a significant amount of preclinical data exists for CCR3 blockade in wAMD, there is no published clinical 
data supporting the therapeutic use of CCR3 in wAMD (Nagai 2015, Wang 2016, Wang 2011)(for further details and 
information, see the 
 for ALK4290).  This study is designed to evaluate potential therapeutic 
effects of ALK4290 on BCVA in wAMD subjects.  Without treatment, patients with wAMD lose an average of 10 
ETDRS letters within 1 year and eventually most patients become legally blind. The current standard of care for 
wAMD is IVT anti-VEGF therapy which usually maintains and improves BCVA. However, for the subset of patients

who do not respond to this treatment (see Section 2.1 above), the therapeutic choices are severely limited.   
Hence, an effective oral treatment, or an oral treatment that provides incremental improvement in BCVA, would be 
considered a substantial medical advance for refractory patients. The aim of this 6-week trial is to investigate whether 
orally administered ALK4290 has the potential to maintain or increase BCVA as measured by ETDRS in subjects who 
have proven to be refractory to IVT anti-VEGF therapy.  If a favorable effect on BCVA is observed, this study would 
potentially provide the basis for longer-term evaluation of the effects of ALK4290 to further assess functional and 
morphological benefits. 
2.3 
POTENTIAL RISKS AND BENEFITS 
 
2.3.1 
KNOWN POTENTIAL RISKS 
 
 
 
 
 
 
 
 
 
 
 
 
 ALK4290 was considered safe and well tolerated by the subjects with wAMD in the trial.  
Potential risks associated with the study design include those related to the study procedures and methodology, 
most notably the potential risks associated with FA including allergic reactions and renal/ thyroid complications.  
 
2.3.2 
KNOWN POTENTIAL BENEFITS 
 
The primary aim of this study is to determine if inhibition of CCR3 with ALK4290 has beneficial functional 
effects related to BCVA as measured by ETDRS.  An effective oral maintenance treatment, or an oral treatment 
that provides incremental improvement in BCVA, would be considered a substantial medical advance and 
provide a therapeutic option for those patients who are refractory (poor- or non-responders) to IVT anti-VEGF 
therapy. A specific aim of the current study is to investigate whether orally administered ALK4290 has the 
potential to improve BCVA.  If a favorable effect is observed, this study could potentially provide the basis for 
longer term studies to evaluate BCVA as well as associated beneficial morphological endpoints.

Hence, the current risk benefit supports administration in modest subject numbers up to an exposure of 6 weeks 
in duration to further investigate therapeutic effects, safety, pharmacokinetics, and morphological outcomes 
related to treatment with ALK4290 in subjects with wAMD.

OBJECTIVES AND PURPOSE 
The primary objective of this study is to investigate the potential therapeutic effects of a 6-week, twice daily oral 
dosing regimen of ALK4290 on BCVA in subjects with refractory wAMD (i.e., following 3 consecutive 
(approximately 4 to 6 weeks apart) IVT anti-VEGF injections in the study eye).  Secondarily, this study aims to assess 
the safety of the study agent.  Exploratory objectives include measuring changes in concentrations of ALK4290 in 
plasma at various time points as well as CST, IRF, SRT, and PED identified by SD-OCT and fundus photography/FA. 
Additionally, pharmacogenomic and biomarker evaluations will be conducted on blood and plasma samples.

SUBJECT WITHDRAWAL OR TERMINATION 
 
5.3.1 
REASONS FOR WITHDRAWAL OR TERMINATION 
 
 
 
A subject will be withdrawn from the study for the following medical or administrative reasons: 
• 
Occurrence of an AE that represents an unacceptable risk to the subject and when continued 
participation in the investigational study is not warranted, in the judgment of the investigator, 
sponsor or medical monitor.  The investigator must follow the subject until the AE resolves or is 
stable 
• 
Treatment with a prohibited concomitant medication other than the use of appropriate 
medications for the treatment of AEs under direction of the investigator 
• 
Subject noncompliance, defined as refusal or inability to adhere to the trial schedule or 
procedures 
• 
At the request of the subject or the subject’s legally authorized representative (e.g., subject 
withdraws consent), investigator, sponsor or regulatory authority 
• 
Pregnancy 
 
5.3.2 
HANDLING OF PARTICPANT WITHDRAWALS OR TERMINATION 
 
 
 
Approximately 30 subjects will be enrolled in the study.  Subjects will be encouraged to complete the study and all 
assessments. However, subjects may voluntarily withdraw at any time, and the investigator may discontinue 
individual subjects from the study at any time.  For subjects who withdraw consent from the study, no study 
procedures will be done thereafter.  For those that withdraw from receiving the study agent, follow-up visits and 
the safety phone follow-up, are to occur per the protocol. Excluding cases of medical emergency but prior to the 
discontinuation of a subject from the clinical study for disease worsening, the study investigator should discuss 
each case of discontinuation with the sponsor and/or the medical monitor. 
 
The subject withdrawal criterion below should be used to assess worsening or disease progression.  In such cases, a 
documented assessment by the principal investigator is required, and subjects with clinically significant disease 
progression should be considered for withdrawal from the study and subsequent initiation of standard of care: 
• 
A BCVA loss of ≥ 5 letters from baseline 
• 
New macular subretinal hemorrhage 
• 
Investigator discretion based on acute worsening of underlying disease or substantial risk to further 
participation in the study 
 
5.4 
PREMATURE TERMINATION OR SUSPENSION OF STUDY 
 
Both the sponsor and the investigator reserve the right to terminate the study at any time.  Should this be necessary, 
both parties will arrange discontinuation procedures and notify the appropriate regulatory authority(ies), IRBs, and 
IECs.  In terminating the study, the sponsor and the investigator will continue to protect the subjects’ privacy and 
identity as required by relevant statues and regulations. 
 
Alkahest, Inc. has the right to terminate a study site from participating in the study at any time. Reasons for study or 
site termination may include, but are not limited to: 
• 
Unsatisfactory subject enrollment (i.e., < 2 subjects enrolled within a 6-month period) 
• 
Unacceptable protocol deviations/violations as assessed by the medical monitor 
• 
Inaccurate or incomplete data entry and recording

ASSESSMENT OF ADVERSE EVENTS 
 
7.2.1.1  
Terminology to Use for Adverse Event Descriptions 
 
When reporting an adverse event, the event description should use the best matching terminology describing the 
event as found in the Common Terminology Criteria for Adverse Events (CTCAE v4.03).  If an available CTCAE 
term fits the event well, no additional descriptors may be needed.  However, necessary descriptions should be 
added in order to clarify the event or to place it in an appropriate context.  The adverse event name should ideally 
be 1-3 words in length with additional description provided elsewhere on the adverse event report.  A copy of the 
CTCAE is provided in the ISF.  Standardized terms from the CTCAE will be used by the sponsor and the Contract 
Research Organization (CRO) to categorize events for reporting to regulatory authorities using the Medical 
Dictionary for Regulatory Activities (MedDRA, v. 20.1).  In most cases, the CTCAE terms match MedDRA 
coding terminology.  If an appropriate term matching the adverse event cannot be found in the CTCAE and the 
preferred MedDRA term is unknown, the AE description should include a diagnosis, sign, or symptom with 
additional information to facilitate subsequent categorization into MedDRA coding terms.

7.2.1.2  
Definition of Adverse Events 
 
7.2.1.2.1 Adverse Event  
 
An AE is defined in the ICH E2D as “any unfavorable or unintended sign, symptom, or disease temporarily 
associated with the use of a medicinal product whether or not considered related to the product.”  Progression or 
worsening of the medical condition under study, by itself, does not necessarily constitute an adverse event unless 
the change can be reasonably attributed to an action of the study agent and not only to its lack of efficacy. Simply 
defining an adverse event does not imply a causal relationship; relatedness to the study agent is defined in Section 
7.2.1.2.4. 
 
7.2.1.2.2 Serious Adverse Event  
 
An SAE is defined for this protocol as any AE that meets one or more of the following criteria: 
 
A. A death (CTCAE Grade 5 event) occurring during the study, whether or not considered treatment-related; 
B. A life-threatening event (CTCAE Grade 4); 
C. An event requiring inpatient hospitalization or prolonged hospitalization due to the adverse event; 
D. An adverse event resulting in a significant, persistent, or permanent change, impairment, damage or 
disruption in the participant’s body function or structure, physical activities or quality of life; 
E. An event that otherwise required a medical or surgical intervention to preclude permanent impairment or 
damage (excluding unrelated elective or cosmetic procedures). 
 
7.2.1.2.3 Grading Severity of Adverse Events 
 
 
The investigator must grade the severity of all reported adverse events into one of the following five (5) categories:  
• 
Grade 1 (Mild) 
• 
Grade 2 (Moderate) 
• 
Grade 3 (Severe) 
• 
Grade 4 (Life-Threatening) 
• 
Grade 5 (Death) 
 
The standardized CTCAE severity grading scales for the specific type of adverse event reported must be used 
when a matching CTCAE term is available.  The highest severity grade experienced for the event should be 
reported.  The initial severity grading may be updated in follow-up reports if the maximum grade changes to a 
higher level.  The CTCAE grading scale should be used according the following guidelines. 
 
 
Grade 1 (Mild) 
 
Transient (< 48 hours) or mild discomforts, no or minimal medical therapy or intervention required, 
hospitalization not necessary, no or little limitation in normal activities, nonprescription or single-use 
prescription therapy may be employed to relieve symptoms (e.g., aspirin for simple headache, acetaminophen 
with codeine for post-surgical pain).  Mild adverse events may be listed as expected consequences of the 
therapy for any given protocol, and standard supportive measures for such an expected event do not necessarily 
elevate the event to a higher grade.

________________________________________________________________________________________________ 
CONFIDENTIAL/PROPRIETARY  
 
Page 24 of 55 
 
Grade 2 (Moderate) 
 
Mild to moderate limitation in activity, some assistance may be needed; possibly none but usually minimal 
intervention/therapy required, hospitalization possible. 
 
Grade 3 (Severe) 
 
Marked limitation in activity, some assistance usually required; medical intervention/therapy required; 
hospitalization possible or likely. 
 
Grade 4 (Life-Threatening) 
 
Extreme limitation in activity, significant and immediate assistance required; significant medical/therapy 
intervention required to prevent loss of life; hospitalization, emergency treatment or hospice care probable. This 
grade is used when the subject was, in the view of the investigator, at substantial risk of dying at the time of the 
adverse event or it was suspected that use or continued use of the study agent would have resulted in the 
subject’s death. 
 
Grade 5 (Death) 
 
Death related to AE. 
 
7.2.1.2.4 Relatedness of Study Agent to Adverse Event 
 
 
The investigator (or an authorized study physician) or sponsor must submit an attribution for the relatedness of the 
reported AE to the study agent. The attribution should take into account both the temporal association and any 
known physical, physiological, or toxicological information regarding the study agent that could reasonably infer 
causality.  The three attribution categories are: 
  
• 
Definite - Clearly related to the study agent.  An adverse event that follows a temporal sequence from 
administration of the study agent; follows a known response pattern to study agent; and, when appropriate 
to the protocol, is confirmed by improvement after stopping the study agent (positive rechallenge; and by 
reappearance of the reaction after repeat exposure (positive rechallenge)); and cannot be reasonably 
explained by known characteristics of the subject’s clinical state or by other therapies. 
• 
Possibly - May be related to the study agent.  An adverse event that follows a reasonable temporal 
sequence from administration of study agent and follows a known response pattern to the study agent, but 
could have been produced by the subject' clinical state or by other therapies. 
• 
Unrelated - Clearly NOT related to the study agent.  An adverse event that does not follow a reasonable 
temporal sequence after administration of the study agent and most likely is explained by the subject’s 
clinical disease state or by other therapies.  In addition, a negative rechallenge to the study agent would 
support an unrelated relationship. 
 
7.2.1.2.5 Worsening of Underlying Disease and/or Other Pre-Existing Conditions  
 
Worsening of the underlying disease and/or of other pre-existing conditions will be recorded as an AE/SAE in the 
eCRF.

7.2.1.2.6 Changes in Safety Evaluations  
 
Changes in vital signs, ECG, physical examination, laboratory test results, and ophthalmic evaluations will be 
recorded as an AE/SAE in the eCRF if they are judged clinically relevant by the investigator. 
 
7.2.1.2.7 Adverse Events of Special Interest 
 
 
The following are considered adverse events of special interest (AESI): 
 
• 
Hepatic injury defined by the following alterations of liver parameters:  
For subjects with normal liver function at baseline an elevation of AST and/or ALT ≥ 3-fold ULN 
combined with an elevation of total bilirubin ≥ 2-fold upper limit of normal (ULN) measured in the 
same blood draw sample. Subjects showing these lab abnormalities need to be followed up according 
to Section 17.1.2. 
• 
Abrupt decrease (> 15 letters lost from baseline) of BCVA  
• 
QTc prolongation (> +50 ms from baseline and > 450 ms) 
 
Protocol-specific AESIs are to be reported in an expedited manner similar to SAEs even if they do not meet any of 
the criteria for an SAE (see Section 7.2.1.2.2). 
 
7.2.1.3  
Adverse Event and Serious Adverse Event Reporting 
 
All AEs, serious and non-serious, occurring during the course of the clinical trial (i.e., from signing the 
informed consent through the follow-up period) will be collected, documented, and reported to the sponsor by 
the investigator on the appropriate eCRF and SAE reporting forms.  
 
For each AE, the investigator will provide the onset date, end date, seriousness, grade, relatedness, treatment 
required, outcome, and action taken with the study agent. The investigator will determine the grade as defined 
in Section 7.2.1.2.3 and the causal relationship to the study agent (relatedness) as defined in Section 7.2.1.2.4. 
 
The investigator must report the following events immediately (within 24 hours or the next business day 
whichever is shorter) to the sponsor or designee (refer to the Lab Manual/ISF for specific instructions): SAEs 
and non-serious AEs relevant to the reported SAE and protocol-specified AESI. 
 
The investigator does not need to actively monitor subjects for adverse events once the clinical trial has ended. 
However, if the investigator becomes aware of an SAE(s) that occurred after the subject has completed the 
clinical trial, it should be reported by the investigator to the sponsor if considered relevant by the investigator. 
 
Any AE occurring during the study must be documented in the subject’s medical records and as an AE in the 
eCRF.  Any SAE occurring during the study must be documented in the subject’s medical records and as an 
SAE in the eCRF. 
 
A separate SAE report should be used for each SAE.  However, if at the time of initial reporting, multiple 
SAEs are present that are temporally and/or clinically related, they may be reported on the same SAE report. 
 
The investigator should attempt to establish a diagnosis of the event (that meets the definition of an AE or 
SAE) based on signs, symptoms, and/or other clinical information.  In such cases, the diagnosis should be

Page 26 of 55 
 
documented as the AE and/or SAE and not the individual signs or symptoms.  The diagnosis will become the 
basis for the verbatim term as reported by the investigator.  If no diagnosis is known and clinical signs and 
symptoms are not present, the abnormal finding should be recorded. 
 
The investigator will take all appropriate and necessary therapeutic measures required for resolution of the 
AE.  Any medication necessary for the treatment of an AE must be recorded on the concomitant medication 
case report form.   
 
The SAE report(s) should be completed as thoroughly as possible and signed by the investigator or his/her 
designee before transmittal to the sponsor or designee (e.g., study CRO).  It is very important that the 
investigator provide his/her assessment of relatedness to the study agent as well as an applicable diagnosis at 
the time of the initial SAE report. 
 
7.2.2 
SAFETY LABORATORY EVALUATIONS 
 
Blood samples and urine must be collected at every visit.  Safety laboratory examinations will include 
hematology, biochemistry, coagulation and qualitative urine analysis. 
• 
Hematology: hemoglobin, red blood cell count (RBC), white blood cell count (WBC) with 
differential, platelets 
• 
Biochemistry: glucose, sodium, potassium, calcium, inorganic phosphate, creatinine, aspartate 
aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (AP), lactate 
dehydrogenase (LDH), total bilirubin (if elevated provide direct bilirubin), urea, total protein, 
albumin, uric acid 
• 
Coagulation: activated partial thromboplastic time (aPTT), prothrombin time (PT)/international 
normalized ration (INR) 
• 
Urine: potential of hydrogen (pH), glucose, erythrocytes, leukocytes, protein, nitrite 
 
Glomerular filtration rate (GFR) will be estimated by the Cockroft Gault Formula utilizing serum creatinine 
(see Section 17.5).  All safety laboratory measurements will be performed by a central laboratory.  
Investigators will get guidance and instructions on laboratory sampling and processing through a separate Lab 
Manual provided by the central laboratory. 
 
The investigator is responsible for determining and documenting if out of range laboratory values are 
clinically significant or not.  All clinically significant values will be recorded as AEs in the eCRF and 
followed until resolution.  Once resolved, the appropriate eCRF page(s) will be updated.  
 
7.2.3 
ELECTROCARDIOGRAM 
 
Twelve-lead ECGs (I, II, III, aVR, aVL, aVF, V1 - V6) will be recorded using a computerized 
electrocardiograph. The ECGs will be recorded for a 10-second duration after the subjects have rested for at 
least 5 minutes in a supine position (see Section 15.1, Schedule of Events Table, for time points). ECGs will 
be stored in the subject’s medical records. ECGs may be repeated for quality reasons and the repeat ECG will 
be used for analysis. Additional ECGs may be collected by the investigator for safety reasons. Abnormal 
findings will be reported as AEs (during the trial) or baseline conditions (at screening) in the eCRF.

STUDY AGENT CONCENTRATION AND PHARMACOKINETICS 
  
Plasma concentration measurements of ALK4290 will be collected to assess systemic exposure to the study agent.  
For sampling time points and further details, please refer to Section 17.3.  
 
7.2.6.1  
Pharmacokinetic Endpoints 
 
 
As far as feasible, the following pharmacokinetic parameters will be derived by noncompartmental methods:  
• 
Cmax   
Maximum concentration of ALK4290 in plasma after single dose 
• 
tmax   
Time of Cmax relative to last dosing 
• 
tmax,ss   
Time of Cmax,ss relative to last dosing 
• 
Cpre,ss,N  
Pre-dose concentration of ALK4290 in plasma immediately before administration  
                       of the Nth dose 
In addition, the average pre-dose concentration in plasma at steady state will be calculated as the geometric 
mean of Cpre,ss,N values. 
 
7.2.6.2  
Methods of Sample Collections 
 
 
For quantification of ALK4290 plasma concentrations and for biomarker investigations (see Section 7.2.8), 
one blood sample of approximately 6 mL per sampling time point (see Section 17.2.1, Table of 
Pharmacokinetic, Biomarker, and Pharmacogenomic Sampling) will be taken from an antecubital or forearm 
vein into a potassium ethylenediaminetetraacetic acid (EDTA)-anticoagulant blood drawing tube. 
The EDTA-anticoagulated blood samples will be centrifuged to collect plasma. For pharmacokinetic samples 
only, the obtained plasma will be split into 2 aliquots and stored in polypropylene tubes. At the selected time 
points with additional biomarker determinations, 5 instead of 2 aliquots of at least 0.5 mL plasma each will be 
prepared from the blood sample. The time from blood collection until the transfer of plasma aliquots into the 
freezer should not exceed 60 minutes, with interim sample storage on wet ice whenever possible. Samples will 
be positioned upright and will be frozen at approximately -20°C or below until shipment.  These aliquots will 
be processed by the central laboratory. Details of plasma collection, sample handling, and shipment 
instructions will be provided in the Lab Manual/ISF. 
 
7.2.6.3  
Analytical Determinations 
 
 
Concentrations of ALK4290 and metabolites (if feasible) in plasma samples will be determined by a validated 
high performance liquid chromatography, tandem mass spectrometry (HPLC-MS/MS) assay.  Leftover 
samples will be used for exploratory biomarker assessment (see Section 7.2.8). 
 
 
7.2.7 
PHARMACOGENOMIC EVALUATIONS 
  
Pharmacogenetic analysis of prespecified genes is mandatory and a prerequisite for participation in this study.

CLINICAL MONITORING 
 
Clinical site monitoring is conducted to ensure that the rights and well-being of human subjects are protected, that 
the reported trial data are accurate, complete, and verifiable, and that the conduct of the trial is in compliance with 
the currently approved protocol/amendment(s), with GCP, and with applicable regulatory requirement(s). 
 
• 
Monitoring for this study will be performed by the study CRO in accordance with the Clinical Monitoring Plan 
(CMP). 
• 
A mix of on-site and centralized risk-based monitoring will be performed to ensure the safety of clinical 
subjects and the accuracy and completeness of study data.  
• 
The sponsor will be provided with copies of monitoring reports per the timelines specified within the CMP. 
• 
Details of clinical site monitoring tasks and scope are documented in the study’s CMP. The CMP describes 
in detail who will conduct monitoring, at what frequency monitoring will be done, at what level of detail 
monitoring will be performed, and the distribution of monitoring reports. 
• 
Independent audits may be conducted by the sponsor in accordance with the Clinical Quality Oversight Plan 
to ensure monitoring practices are performed consistently across all participating sites and that monitors are 
following the CMP.

STATISTICAL CONSIDERATIONS 
10.1 
STATISTICAL DESIGN MODEL AND ANALYTICAL PLANS 
The therapeutic effect of the treatment will be investigated in one single group of subjects, with no control group. 
The observed mean effect will be compared with 0 as reference value.  Overall baseline and demographic data will 
be summarized using descriptive statistics.  
Subject disposition (e.g., the number of subjects enrolled, completed, and discontinued) will be summarized and 
medical history data will be listed. Prior and concomitant medications taken from screening and during the study 
will be categorized by World Health Organization (WHO) classification for therapeutic class and drug name, listed 
and summarized by number and percentage of subjects.   
Final analyses are not limited to the summaries described herein.  Analytical details and assumptions will be fully 
presented in the SAP. 
 
10.2 
STATISTICAL HYPOTHESES 
The null and alternative hypothesis for change from baseline in BCVA letter score as measured by ETDRS testing 
method are:  
 
H0: Change from baseline in BCVA letter score = 0 
 
H1: Change from baseline in BCVA letter score ≠ 0 with α1= 0.20 
 
10.3 
ANALYSIS DATASETS 
 
Four analysis datasets are possible; however, analyses may not necessarily be conducted with all four:

• Intention-to-Treat (ITT) Dataset: all enrolled subjects 
• Safety Dataset: all subjects who received at least 1 dose of the study agent  
• Evaluable Dataset:  all subjects who complete at least 3 weeks of treatment during the 6-week 
treatment period 
• Per Protocol Dataset:  a subset of the Evaluable Dataset comprised of subjects who have no major 
protocol violations 
 
The presentation of baseline characteristics will be based on the ITT dataset.  All safety analyses will be performed for 
the Safety Dataset.  Analyses of the primary and exploratory endpoints will focus on the Evaluable and/or Per Protocol 
Datasets. 
 
10.4 
PLANNED ANALYSES  
 
10.4.1 
ANALYSIS OF THE PRIMARY ENDPOINT 
 
The therapeutic effect of the treatment will be investigated in one single group of subjects, with no control group. 
The changes from baseline in BCVA will be compared with 0 as reference value.  The study is not designed to 
detect significant changes in BCVA over time.  However, using available data, including changes in BCVA from 
baseline, descriptive summarization will be developed.  Of particular interest will be the within-subject changes 
in BCVA from baseline and their distribution around a null value of zero.   
 
10.4.2 
ANALYSIS OF THE SECONDARY ENPOINT 
 
Safety will be assessed for the following endpoints: 
• Incidence, seriousness, and severity of adverse events 
• Changes from baseline in clinical laboratory values 
• Changes from baseline in physical examination 
• Changes from baseline in vital signs 
All treated subjects (i.e., all subjects who received at least 1 dose of the study agent) will be included in the safety 
evaluation.  Safety analyses will be descriptive in nature and will be based on accepted standards. 
 
Tabulations of frequencies/proportions will be used for the evaluation of categorical (qualitative) data, and 
tabulations of descriptive statistics will be used to evaluate continuous (quantitative) data. 
 
 
10.4.3 
EXPLORATORY ANALYSES 
 
Observed values as well as changes from baseline in CST, IRF, SRF, and PED as measured by SD-OCT and 
fundus photography/FA will be summarized using descriptive statistics.  Pharmacokinetic, biomarker, and 
pharmacogenomic analyses will be carried out using an exploratory approach to investigate the potential influence 
on the therapeutic response of ALK4290.

10.4.4 
PLANNED INTERIM ANALYSES 
Continuous data monitoring will be performed. One interim analysis will be performed when 2/3 of all entered 
subjects have reached Day 15 (Visit 4). It will include only the primary and a subset of the secondary 
endpoints, (i.e., mean change in BCVA as measured by ETDRS and the accumulated AE information). 
Recruitment into the trial will be stopped if the interim analysis shows relevant safety problems with 
ALK4290.  No formal futility analysis will be conducted. 
 
10.5 
SAMPLE SIZE 
 
A total of 30 subjects will be enrolled in the study with the intent of obtaining ~25 evaluable subjects who have 
completed at least 3 weeks of treatment and evaluations through Visit 4.  Subjects who discontinue prior to Visit 4 
may be replaced.  Subjects who withdraw or are withdrawn during screening will be replaced.  The study is not 
powered for detecting statistically significant differences in therapeutic parameters in subjects with wAMD receiving 
ALK4290.  However, the proposed sample size may be sufficient to identify trends in the effects of ALK4290 and in 
the relationship between dose and response. 
 
11 
SOURCE DOCUMENTS AND ACCESS TO SOURCE DATA/DOCUMENTS 
 
Each participating site will maintain appropriate medical and research records for this trial, in compliance with  
ICH E6 R2 and regulatory and institutional requirements for the protection of confidentiality of participants. Each site 
will permit authorized representatives of regulatory agencies, the IRB/IEC, the sponsor, or the sponsor’s 
representatives to examine (and when permitted by applicable law, to copy) clinical records for the purposes of quality 
assurance reviews, audits, and evaluation of the study safety, progress, and data validity.  
 
Source data are all information, original records of clinical findings, observations, or other activities in a clinical trial 
necessary for the reconstruction and evaluation of the trial. Examples of these original documents and data records 
include, but are not limited to, hospital records, clinical and office charts, laboratory notes, memoranda, participant’s 
memory aids or evaluation checklists, pharmacy dispensing records, recorded audio tapes of counseling sessions, 
recorded data from automated instruments, copies or transcriptions certified after verification as being accurate and 
complete, microfiches, photographic negatives, microfilm or magnetic media, x-rays, and participant files and 
records kept at the pharmacy, at the laboratories, and medico-technical departments involved in the clinical trial.  
 
It is not acceptable for the eCRF to be the only record of a subject’s participation in the study. This is to ensure 
that anyone who would access the medical record has adequate knowledge that the subject is participating in a 
clinical trial.  Source document templates will be developed for this study. 
 
12 
ETHICS/PROTECTION OF HUMAN SUBJECTS 
12.1 
ETHICAL STANDARD 
 
The study will be conducted in compliance with the protocol, the principles laid down in the Declaration of Helsinki, 
and in accordance with the ICH Harmonized Tripartite Guideline for GCP.

information sheets, or descriptions of the study used to obtain informed consent) will be submitted by the investigator 
to an IRB or IEC.  Approval from the IRB/IEC must be obtained before starting the study and should be documented in 
a letter to the investigator specifying the protocol number, protocol version, documents reviewed, and date on which 
the committee met and granted the approval.  
 
All changes to the consent form will be IRB approved; a determination will be made regarding whether previously 
consented participants need to be re-consented. 
 
Any modifications or amendment to the protocol must also be submitted to the IRB/IEC for approval prior to 
implementation. 
 
12.3 
INFORMED CONSENT PROCESS 
 
12.3.1 
CONSENT FORMS 
 
Consent forms describing in detail the study agent, study procedures, and risks are given to the participant and 
written documentation of informed consent is required prior to any invasive study procedures.  
 
12.3.2 
CONSENT PROCEDURES AND DOCUMENTATION 
 
It is the responsibility of the investigator or designee to obtain written informed consent from each subject 
participating in this study and/or their legally authorized representative after adequate explanation of the aims, 
methods, objectives, and potential hazards of the study and prior to undertaking any study-related procedures. 
 
Subjects should have the opportunity to discuss the study with their family members or other advisors and the time 
to consider participation in the trial carefully. The participants may withdraw consent at any time throughout the 
course of the trial. The rights and welfare of the participants will be protected by emphasizing to them that the 
quality of their medical care will not be adversely affected if they decline to participate in this study. 
 
The investigator or designee must utilize an IRB/IEC-approved consent form that contains the elements required 
by ICH GCP and applicable regulatory requirements for documenting written informed consent.  Each informed 
consent will be appropriately signed and dated by the subject and/or their legally authorized representative and the 
person obtaining consent.  A copy of the signed consent form will be provided to the subject and/or their legally 
authorized representative.  By signing the informed consent form, all parties agree they will complete the 
evaluations required by the study, unless they withdraw voluntarily or are terminated from the study for any 
reason. 
 
Investigators will be expected to maintain a screening log of all potential study candidates that includes limited 
information about the potential candidate (e.g., date of screening).  
 
All subjects who provide consent will be assigned a unique study number.  This number will be used to identify the 
subject throughout the clinical study and must be used on all study documentation related to the study subject.  
Once a number is assigned to a subject, that number will remain with that study subject and will not be reused. 
 
If an individual’s medical chart or results of diagnostic tests performed as part of an individual’s regular 
medical care are going to be used for screening, written informed consent must be obtained prior to review of

that information. 
 
12.4 
DATA CONFIDENTIALITY  
Subject confidentiality is held in strict trust by the participating investigators, their staff, the sponsor and their agents. 
This confidentiality is extended to cover testing of biological samples and genetic tests in addition to the clinical 
information relating to participants. Therefore, the study protocol, documentation, data, and all other information 
generated will be held in strict confidence. No information concerning the study or the data will be released to any 
unauthorized third party without prior written approval of the sponsor. 
 
The study monitor, other authorized representatives of the sponsor, representatives of the IRB/IEC or government 
regulatory agencies may inspect documents and records required to be maintained by the investigator, including but not 
limited to, medical records (office, clinic, or hospital) and pharmacy records for the participants in this study. The 
clinical study site will permit the study monitor to access to such records. 
 
The investigator must assure that subjects’ anonymity will be strictly maintained and that their identities are protected 
from unauthorized parties. Only subject initials and an identification code (i.e., not names) should be recorded on non-
local lab samples, requisitions and any documents submitted to the CRO, sponsor and/or IRB/IEC.  The investigator 
must keep a subject log showing codes, names, and addresses for all subjects screened and for all subjects enrolled in 
the trial. The study participant’s contact information will be securely stored at each clinical site for internal use during 
the study. At the end of the study, all records will continue to be kept in a secure location for as long a period as 
dictated by local IRB/IEC and Institutional regulations. 
 
12.5 
FUTURE USE OF STORED SPECIMENS 
 
With the subject’s (or the subject’s legally authorized representative’s) approval and as approved by local IRB/IECs, 
de-identified biological samples may be stored at Alkahest, or designee, for future use. These samples could be used 
for research and to improve treatment. Alkahest will also be provided with a code-link that will allow linking the 
biological specimens with the specific data from each subject, maintaining the masking of the identity of the study 
subject. 
 
During the conduct of the study, an individual subject can choose to withdraw consent to have biological specimens 
stored for future research. However, withdrawal of consent for biospecimen storage will not be possible after the study 
is completed. 
 
When the study is completed, access to study data and/or samples will be managed by Alkahest.  
 
12.6 
EXPEDITED REPORTING OF ADVERSE EVENTS 
 
Expedited reporting of serious adverse events to health authorities and IECs/IRBs, will be done according to local 
regulatory requirements. Further details regarding this reporting procedure are provided in the ISF. 
 
13 
DATA HANDLING AND RECORD KEEPING 
13.1 
DATA COLLECTION AND MANAGEMENT RESPONSIBILITIES 
 
Data collection is the responsibility of the clinical trial staff at the site under the supervision of the site

investigator. The investigator is responsible for ensuring the accuracy, completeness, and timeliness of the data 
reported. 
 
Source documents provide evidence for the existence of the subject and substantiate the integrity of the data 
collected. Source documents are filed at the investigator’s site.  Data entered in the eCRFs that are transcribed 
from source documents must be consistent with the source documents or the discrepancies must be explained. All 
source documents should be completed in a neat, legible manner to ensure accurate interpretation of data. Black or 
blue ink is required to ensure clarity of reproduced copies. When making changes or corrections, cross out the 
original entry with a single line, and initial and date the change. DO NOT ERASE, OVERWRITE, OR USE 
CORRECTION FLUID OR TAPE ON THE ORIGINAL. The investigator may need to request previous medical 
records or transfer records, depending on the trial; also, current medical records must be available. 
 
For each subject who receives the study agent, the eCRF must be completed in a timely manner.  The investigator 
will review and approve the eCRF for each study subject after all data have been entered, the eCRFs have been 
source document verified, and all queries have been resolved. This also applies to records for those subjects who 
fail to complete the study.  If a subject withdraws from the study, the reason must be noted on the eCRF.  If a 
subject is withdrawn from the study because of an AE, thorough efforts should be made to clearly document the 
outcome. 
 
All data collection and recordkeeping procedures must be compliant with applicable ICH GCP. 
 
13.1.1 
INVESTIGATOR RESPONSIBILITIES 
 
The investigator will comply with the protocol (which has been approved/given favorable opinion by an IRB/IEC), 
ICH GCP, and applicable regulatory requirements. The investigator is ultimately responsible for the conduct of all 
aspects of the study at the study site and verifies by signature the integrity of all data transmitted to the sponsor. 
The term “investigator” as used in this protocol as well as in other study documents, refers to the investigator or 
authorized study personnel that the investigator has designated to perform certain duties. Sub-investigators or other 
authorized study personnel are eligible to sign for the investigator, except where the investigator’s signature is 
specifically required. 
 
13.1.2 
STUDY FILES 
 
The investigator must maintain adequate and accurate records to enable the conduct of the study to be fully 
documented and the study data to be subsequently verified.  These documents should be classified into two 
separate categories (although not limited to) the following: (1) investigator’s study file, and (2) subject clinical 
source documents. 
 
The investigator’s study file will contain the protocol/amendments, eCRF, IRB/IEC approval with correspondence, 
informed consents, drug records, staff curriculum vitae and authorization forms, and other appropriate documents 
and study-specific manuals (e.g., Lab Manual). 
 
Subject clinical source documents would include (although are not limited to) the following: subject hospital/clinic 
records, physician’s and nurse’s notes, appointment book, original laboratory reports, ECG, radiologic imaging, X-
ray, pathology and special assessment reports, consultant letters, screening and enrollment log, etc.

Page 41 of 55 
 
13.2 
STUDY RECORDS RETENTION 
 
All clinical study documents must be retained by the investigator until two years after the study is discontinued and 
regulatory authorities have been notified.  Before the investigator destroys any material related to the clinical study, 
he/she must obtain approval in writing from the sponsor. 
 
The investigator should keep a file where the full name and address of the subject and all signed informed consents are 
included for at least 15 years after completion of the trial. Any original study-related information that permits 
verification of inclusion and exclusion criteria, including clinical history, a copy of all data collection logs, and 
documents on the use of the study agent, must be stored for as long a time period as permitted by the center.  
Should the investigator wish to move study records to another location, arrangements must be made to store these in 
sealed containers so that they can be returned sealed to the investigator in case of a regulatory audit. Where source 
documents are required for the continued care of the Subject, appropriate copies should be made for storage outside of 
the site. 
 
13.3 
PROTOCOL NONCOMPLIANCE: DEVIATIONS AND VIOLATIONS 
 
A protocol deviation is any noncompliance with the clinical trial protocol or with GCP. The noncompliance may be 
either on the part of the subject, the investigator, or the study site staff. When deviations occur, corrective actions 
are to be developed by the site and implemented promptly. 
 
These practices are consistent with ICH E6: 
• 
4.5 Compliance with Protocol, sections 4.5.1, 4.5.2, and 4.5.3 
• 
5.1 Quality Assurance and Quality Control, section 5.1.1 
• 
5.20 Noncompliance, sections 5.20.1, and 5.20.2. 
 
Protocol Deviations are instances of protocol noncompliance that DO NOT have the potential to affect the safety of 
subjects.  Protocol Deviations do not require review by the medical monitor. 
• 
5.20 Noncompliance, sections 5.20.1, and 5.20.2. Violations are instances of protocol noncompliance 
that DO have the potential to affect the safety of subjects.  Violations are a subset of Protocol 
Deviations. 
 
All instances of protocol noncompliance will be logged and tracked by the site and CRO.  Periodic review of Protocol 
Deviations will inform assessment of site performance. 
 
It is the responsibility of the site to use continuous vigilance to identify and report deviations promptly to the study 
CRO and/or sponsor. All deviations must be addressed in study source documents. Protocol deviations must be sent to 
the local IRB/IEC per their guidelines. The site investigator/study staff is responsible for knowing and adhering to their 
IRB/IEC requirements. 
 
13.4 
PUBLICATION AND DATA SHARING POLICY 
 
Any formal presentation or publication of data collected as a direct or indirect result of this trial will be considered as a 
joint publication by the investigator(s) and the sponsor. In the case of multicenter studies, it is mandatory that the first 
publication be made based on the totality of data obtained from all centers, analyzed as stipulated in the protocol, and 
presented and interpreted as documented in the final Clinical Study Report (CSR). The resulting publication will name

Page 42 of 55 
 
investigators according to the policy of the chosen journal. Where it is not permitted for all investigators to be included 
as authors, the publication will name all investigators within the publication. 
 
Individual investigators may publish data arising from their own subjects. The investigator will provide the sponsor 
with copies of written publications (including abstracts and posters) at least 60 days in advance of submission. This 
review is to permit the sponsor to review the communication for accuracy (thus avoiding potential discrepancies with 
submissions to regulatory authorities), to verify that confidential information is not inadvertently divulged (including 
patent protection), to allow adequate input or supplementary information that may not have been available to the 
investigator, and to allow establishment of co-authorship.  
 
Investigators participating in multicenter studies must agree not to engage in presentations based on data gathered 
individually or by a subgroup of centers before publication of the first main publication, unless this has been agreed 
otherwise by all other investigators and the sponsor. However, in the event that no publication of the overall results has 
been submitted after approval of the CSR, investigators may publish results of one or more center’s subjects to the 
same review as outlined above. The sponsor will circulate proposed multicenter publications to all investigators for 
review. 
 
Data will be reviewed by all participating investigators prior to publication. The study sponsor will have 60 days to 
review all definitive publications, such as manuscripts and book chapters, and a minimum of 30 days to review all 
abstracts. 
 
Sponsor reserves final approval and editing rights for all publications or abstracts that consider aggregated data from 
more than one individual site. 
 
13.5 
COMPLETION OF TRIAL 
 
The EMA/competent authority in each participating EU member state needs to be notified about the end of the trial 
(last subject out) or early termination of the trial. 
 
14 
FINANCIAL DISCLOSURE AND CONFLICT OF INTEREST POLICY 
 
A separate financial disclosure agreement will be made between each principal investigator and Alkahest, Inc. or its 
authorized representative before the study agent is shipped.  Each investigator will notify Alkahest, Inc. or its 
authorized representative of any relevant changes during the conduct of the study and for 1 year after the study has 
been completed.  Alkahest and the study CRO will evaluate any disclosed conflicts of interest and will establish a 
mechanism for their management.

1. All subjects must sign an informed consent consistent with ICH-GCP guidelines prior to any trial related procedures, which includes medication washouts 
and restrictions.  
2. Informed consents must be obtained for pharmacogenomic sampling 
. Pharmacogenomics sampling will be performed at 
enrollment/baseline (Visit 2). 
 
. 
3. A preliminary check of inclusion/exclusion criteria will be performed at screening (Visit 1) after obtaining informed consents. 
4. Study agent will be self-administered in the clinic under supervision of study personnel during every visit of the treatment period (Visits 2-8) following all 
safety and ophthalmic assessments.  Training on study agent administration will be conducted prior to the initial study agent administration at Visit 2.   
5. A pre-dose pharmacokinetic (PK) blood sample will be taken to be centrifuged for collection of plasma samples. Biomarker plasma aliquots will be 
obtained from the pharmacokinetic (PK) samples.  At Visit 2 only, four post-dose pharmacokinetic blood samples will be taken. 
6. A pre-dose PK blood sample will be taken to be centrifuged for collection of plasma samples. 
7. End of Treatment (EOT) visit (Visit 8): all study related procedures will be conducted at the conclusion of 6 weeks of treatment on Day 43 ±1. Withdrawal 
of consent is allowed at any time. For subjects who withdraw consent from the study, no study procedures will be done thereafter. For those that withdraw 
from the study agent, follow-up visits are to occur as per the protocol. Excluding cases of medical emergency, but prior to the discontinuation of a subject 
from the clinical study for disease worsening, the study investigator should discuss each case of discontinuation with the sponsor. 
8. Adverse events and concomitant medications will be assessed at every study visit as well as recorded at any unscheduled subject contact (e.g., unscheduled  
phone calls, etc.).  Following completion of study agent treatment (Visits 2-8), all current medications will be assessed in the follow-up period. 
9. Pregnancy test required in Poland only per Inclusion Criteria.

PHARMACOKINETIC MEASURES AND EVALUATION 
 
17.3.1 
TIMING OF PHARMACOKINETIC BLOOD SAMPLING 
For the time schedules of pharmacokinetic blood samples, please refer to Section 17.2.1.  PK samples will be taken 
from all subjects at Visits 2-9.   
 
17.3.2 
PHARMACOKINETIC SAMPLE HANDLING AND SHIPMENT 
Methods of pharmacokinetic sample collection are described in Section 7.2.6.2.  Further instructions for sampling 
procedures, and for handling, storage and shipment of the samples will be provided in the Lab Manual in the ISF.   
 
17.3.3 
PHARMACOKINETIC DATA EVALUATION 
For pharmacokinetic analysis and displays, concentrations will be presented in the same format as reported in the 
bioanalytical report.  Only concentrations within the validated concentration range and actual sampling times will 
be used for the calculation of pharmacokinetic parameters. 
Noncompartmental pharmacokinetic analyses of the plasma concentration-time data will be performed using a 
validated software program and for this purpose the actual sampling time for pre-dose samples will be set to zero. 
Plasma concentrations will be plotted graphically versus time for all subjects as listed in the plasma concentration-
time tables. For the presentation of mean profiles, the arithmetic and geometric mean and the planned blood 
sampling times will be used. 
Individual tmax(,ss) values will be directly determined from the plasma concentration time profiles of each subject.  
The following descriptive statistics will be calculated for concentration data and PK parameters: N, arithmetic 
mean, standard deviation, minimum, median, maximum, 10th, 25th, 75th, and 90th percentiles, arithmetic coefficient 
of variation, geometric mean, and geometric coefficient of variation.  Individual concentration values/PK 
parameters may be excluded from calculation of descriptive statistics and graphical displays, e.g. due to relevant 
deviation of actual versus planned sampling time.  Such data however will be listed associated with an appropriate 
flag.

17.3.4 
HANDLING OF MISSING DATA 
In the noncompartmental analysis, concentration data identified with NOS, NOR, and NOA will not be considered. 
Values that are below the limit of quantification (BLQ) and with no peak detectable (NOP) in the lag phase will be 
set to zero.  The lag phase is defined as the period between time zero and the first timepoint with a concentration 
above the quantification limit. All other BLQ and/or NOP values of the profile will be ignored.  Every effort will 
be made to include all concentration data in an analysis. If not possible, a case by case decision is required whether 
the value should be excluded. 
Descriptive statistics of concentrations will be calculated only when at least 2/3 of the individuals have 
concentrations within the validated concentration range. The overall sample size to decide whether the '2/3' rule is 
fulfilled will be based on the total number of samples intended to be drawn for that time point (i.e., BLQ, NOR, 
NOS, NOA, NOP are included).  Descriptive statistics of parameters are calculated only when at least 2/3 of the 
individual parameter estimates of a certain parameter are available.

to a circular area of diameter of 1 mm from the center 
point of the retina that can be measured by investigators 
without the need for a central reader.

• Poland: Female subjects must not be pregnant or 
breastfeeding. Women of childbearing potential must 
have a negative serum pregnancy test at screening/visit 1, 
the first treatment visit, and the last treatment visit. 
Women of childbearing potential and men must agree to 
use highly effective contraception (Clinical Trial 
Facilitation Group 2014) prior to study entry. A woman is 
considered of childbearing potential following menarche 
and until becoming postmenopausal (no menses for at 
least 2 years without an alternative cause). Should a 
woman become pregnant or suspect she is pregnant while 
she or her partner is participating in the study, she should 
inform her treating physician immediately

1. Introduction 
The purpose of this statistical analysis plan (SAP) is to describe the planned analyses and reporting for 
protocol ALK4290-202, Version 3.0 dated 15MAY2018 and Clarification Memorandum #2 dated 
12JUL2018. 
This SAP is being written with due consideration of the recommendations outlined in the most recent 
International Conference on Harmonization (ICH) E9 Guideline entitled Guidance for Industry: Statistical 
Principles for Clinical Trials and the most recent ICH E3 Guideline, entitled Guidance for Industry: 
Structure and Content of Clinical Study Reports (CSR). 
This SAP describes the data that will be analyzed and the subject characteristics, efficacy, and safety 
assessments that will be evaluated. This SAP provides details of the specific statistical methods that 
will be used. The statistical analysis methods presented in this document will supersede the statistical 
analysis methods described in the clinical protocol. If additional analyses are required to supplement 
the planned analyses described in this SAP they may be completed and will be identified in the CSR. 
2. Study Objectives 
The primary objective of this study is to investigate the potential therapeutic effects of a 6-week, twice 
daily oral dosing regimen of ALK4290 on best corrected visual acuity (BCVA) in patients with refractory 
Wet Age-Related Macular Degeneration (wAMD) (i.e., following 3 consecutive [approximately 4 to 6 
weeks apart] intravitreal [IVT] anti-vascular endothelial growth factor [VEGF] injections in the study 
eye).The secondary objectives are to assess the safety of the proposed dosing regimen. 
3. Study Variables 
 
3.1 
Primary Variable 
• 
Mean change from baseline in BCVA letter score as measured by the Early Treatment Diabetic 
Retinopathy Study (ETDRS) testing method at 6-weeks 
 
3.2 
Secondary Variable 
• 
Safety as assessed by incidence, seriousness, and severity of adverse events (AE) 
 
3.3 
Exploratory Variables 
• 
Changes in concentrations of ALK4290 in plasma at various time points 
• 
Changes in central subfield thickness (CST), intraretinal fluid (IRF), subretinal fluid (SRF), and 
pigment epithelial detachment (PED) as measured by spectral domain optical coherence 
tomography (SD-OCT) and fundus photography/fundus angiography (FP/FA) 
• 
Evaluation of pharmacogenomic characteristics and biomarkers in blood and plasma samples

3.4 
Statistical Hypotheses 
The null and alternative hypotheses for change from baseline in BCVA letter score as measured 
by ETDRS testing method are as follows: 
H0: Mean change from baseline in BCVA letter score at 6 weeks = 0 
H1: Mean change from baseline in BCVA letter score at 6 weeks ≠ 0 
The hypothesis testing will be at a two-sided Type I error rate (α) of 0.20. Specifics of the statistical tests 
are provided in Section 14. 
4. Study Design and Procedures 
 
4.1 
General Study Design 
This is a single arm, open-label study to evaluate the therapeutic effects and safety of a 6-week 
treatment regimen of ALK4290 in patients with refractory wAMD. This study enrolls patients with 
refractory active Choroidal Neovascularization (CNV) secondary to AMD who have received at least 
three consecutive (approximately 4-6 weeks) IVT anti-VEGF injections prior to screening. All subjects 
will receive the investigational treatment ALK4290 at a daily dosage of 800 mg administered orally twice 
a day as 400 mg tablets for 6 weeks. At every visit, safety and tolerability assessments will occur. At 
specified visits, BCVA will be measured by the ETDRS testing method and morphological evaluations 
will be conducted utilizing SD-OCT and FP/FA. 
The study eye is defined as the eye that meets all the inclusion criteria and none of the exclusion criteria. 
If both eyes meet the inclusion and none of the exclusion criteria, the study is selected by the 
investigator, per their discretion. 
The overall duration of the study is approximately 10 months from study initiation (i.e., first subject 
enrolled) to study completion (i.e., last subject last visit) with a targeted recruitment of 30 subjects over 
the accrual period. The subject participation period is 10 weeks (6-week treatment plus 4-week follow- 
up), unless prematurely discontinued.

1.
All subjects must sign an informed consent consistent with ICH-GCP guidelines prior to any trial related procedures,
which includes medication washouts and restrictions.
2.
3.
A preliminary check of inclusion/exclusion criteria will be performed at screening (Visit 1) after obtaining informed
consents.
4.
Study agent will be self-administered in the clinic under supervision of study personnel during every visit of the treatment
period (Visits 2-8) following all safety and ophthalmic assessments. Training on study agent administration will be
conducted prior to the initial study agent administration at Visit 2.
5.
A pre-dose PK blood sample will be taken to be centrifuged for collection of plasma samples. Biomarker plasma aliquots
will be obtained from the PK samples. At Visit 2 only, four post-dose PK blood samples will be taken.
6.
A pre-dose PK blood sample will be taken to be centrifuged for collection of plasma samples.
7.
End of Treatment (EOT) visit (Visit 8): all study related procedures will be conducted at the conclusion of 6 weeks of
treatment on Day 43 ±1. Withdrawal of consent is allowed at any time. For subjects who withdraw consent from the
study, no study procedures will be done thereafter. For those that withdraw from the study agent, follow-up visits are to
occur as per the protocol. Excluding cases of medical emergency, but prior to the discontinuation of a subject from the
clinical study for disease worsening, the study investigator should discuss each case of discontinuation with the sponsor.
8.
Adverse events and concomitant medications will be assessed at every study visit as well as recorded at any
unscheduled subject contact (e.g., unscheduled
phone calls, etc.). Following completion of study agent treatment (Visits 2-8), all current medications will be assessed in
the follow-up period.
9.
Pregnancy test required in Poland only per Inclusion Criteria.

5. Study Treatments 
This is a single arm, open-label study. All subjects will receive the investigational treatment ALK4290 at 
a daily dosage of 800 mg administered orally twice a day as 400 mg tablets for 6 weeks. 
6. Sample Size and Power Considerations 
A total of 30 subjects will be enrolled in the study with the intent of obtaining approximately 25 evaluable 
subjects who would complete at least 3 weeks of treatment and evaluations through Visit 5 (Day 22). 
Subjects who discontinue prior to Day 22 may be replaced. Subjects who withdraw or are withdrawn 
during screening (prior to completing V2) will be replaced. The study is not powered for detecting 
statistically significant differences in therapeutic parameters in subjects with wAMD receiving ALK4290. 
7. Data Preparation 
Data management procedures, including database design and selection of the data dictionary will be 
performed by the Data Manager and reviewed and approved by the Sponsor. Auto-coding of all AEs, 
medical histories and concomitant medications will be performed by the IBM Clinical Development EDC 
system with additional manual coding performed by the Sponsor designated medical coder. Medical 
coding will be reviewed by the GCT Medical Monitor and confirmed and approved by the Sponsor. All 
reported study data will be recorded on the electronic Case Report Forms (eCRF) using IBM Clinical 
Development and transferred to SDC by ProTrials. Clinical personnel at the study site and the CRO are 
responsible for ensuring that the protocol is followed and that the eCRFs are properly completed. 
Additional safety lab data external to the eCRF data will be provided by Synevo to ProTrials to be 
reconciled with the EDC data and transferred separately to SDC for analysis. External PK data will be 
transferred from KCAS and will be analyzed by SDC as outlined in the PK plan (separate from the SAP). 
 
 
All Subject IDs will be assigned automatically within the EDC. The Subject ID consists of 9 numbers: 
the first set of 3 numbers are specific for the protocol number (i.e., 202); the second set of 3 numbers 
are specific for the site number (i.e., 001 through 012), and the third set of 3 numbers are the subject 
specific screening number (e.g., 001, 002, etc.). 
After data are entered into EDC, data are reviewed and verified by the clinical monitoring/operations 
CRO and ProTrials Data Management. Additionally, SAE reconciliation of the Clinical Database is 
performed against the Alkahest Global Safety Database and any issues are resolved. When the 
database has been confirmed to be complete, consistent and accurate, the database will be locked 
according to ProTrials Standard Operating Procedures and study specific Data Management Plan. Any

Unless specified otherwise, all ocular assessments and efficacy outcome measures are with respect to 
the study eye, here hence. Data collected for the fellow eye (non-study eye) will be included in subject 
listings and may be analyzed. 
Study day will be calculated as (Date of Visit) – (Date of Initiation of Investigational Medicinal Product 
[IMP]) + 1 for visits after initiation of IMP and as (Date of Visit) – (Date of Treatment Initiation) for visits 
prior to initiation of IMP. 
 
9.1 
Missing or Inconclusive Data Handling 
In general there will be no imputation of missing data other than for partial or missing dates. Partial start 
and end dates for medical history, concomitant medications, and AEs will be imputed as outlined in 
Appendix 1. Completely missing dates will only be imputed for AEs. 
The original dates will be displayed in data listings along with the relative study day for complete dates. 
imputed dates will be used in derivations only (e.g., to determine treatment-emergence status, etc.). 
 
9.2 
Definition of Baseline 
Baseline measures are defined as the last measure prior to the initiation of study treatment, usually at 
Visit 2 (Day 1). For assessments that are not performed at Visit 2 (i.e. FP and FA), the screening Visit 
1 measures will be considered as baseline. 
 
9.3 
Visit Windows and Visit Mapping 
The following table lists the scheduled visits and planned study day along with the corresponding visit 
window that will be used to map visits occurring outside of the scheduled times.

Quantitative variables will be summarized using descriptive statistics including the number of 
observations (n), mean, standard deviation (SD), median, minimum, and maximum values. Means, 
medians, and confidence intervals (CI) will be reported to two decimal places and SDs to three. 
Summaries for discrete variables will include frequency counts and percentages. All percentages will 
be rounded to one decimal place (i.e., XX.X%). Change from baseline will be calculated as the value 
at follow-up visit minus baseline. 
The primary efficacy analysis will be evaluated at a two-sided significance level of 0.20. All p-values will 
be rounded to four decimal places; p-values less than 0.0001 will be presented as “<0.0001”; p-values 
greater than 0.9999 will be presented as “>0.9999”. 
 
9.5

11. Demographic and Baseline 
 
11.1 
Demographic and Vital Signs 
Demographic variables collected in this study include age in years (at time of screening), sex, race, 
ethnicity, body mass index (BMI), weight, height, iris color, and study eye (OD or OS). Subjects who 
record more than one race will be grouped into a single category denoted as ‘Multiple Race’. 
Age (years) will be summarized using continuous descriptive statistics. Age will also be categorized as 
follows: <65 years and ≥65 years. 
 
The number and percentage of subjects will be presented for age category, sex, race, ethnicity, iris color 
and study eye (OD or OS). Percentages will be based on the total number of subjects in the ITT set. A 
subject listing that includes all demographic variables will be provided. 
 
11.2 
Baseline Characteristics 
Baseline BCVA letter score as measured by the ETDRS testing method; CST, presence and height of 
IRF, SRF, and PED as measured by SD-OCT; and presence and size of CNV and leakage from CNV 
as measured by FP/FA will be included in the relevant summaries (including the demography 
summary) and listings. 
 
Prior anti-VEGF IVT treatments will be collected at Screening (Visit 1) for which a subject listing will be 
provided. 
 
12. Medical History and Concomitant Medications 
 
12.1 
Medical History 
Medical history will be summarized using discrete summary statistics and presented at the subject level 
by system organ class (SOC) and preferred term (PT). If a subject reports the same PT multiple times 
within the same SOC, that PT will only be counted once within that SOC. As with the PT, if a subject 
reports multiple conditions within the same SOC, the SOC will only be counted once. Separate tables 
will be created for ocular and non-ocular medical history. Medical history will be coded using MedDRA, 
Version 21.0. The summaries will be based on the ITT set. 
Listings of relevant medical history, including prior medical history within three months prior to Visit 1 
(Screening) will be captured in the appropriate eCRF. A subject listing of reported medical history with 
start and stop dates (or ongoing) will be provided.

12.2 
Prior and Concomitant Medications/Treatments 
At the screening Visit 1 (Day -7 to Day -2), subjects will be asked what medications they are taking, as 
well as those the subject may have taken prior to screening. At each subsequent study visit, subjects 
will be asked what concomitant medications they are currently taking or if there have been any changes 
to their medication since the previous visit. 
All prior and concomitant ocular and non-ocular medications will be listed using the ITT set including 
generic name, route of administration, start date, stop date, dosage, and indication. Prior and 
concomitant medications will be categorized by WHO Drug Dictionary (B3 Global March 2018 or higher) 
classification for therapeutic class and drug name. 
Counts and percentages of ocular and non-ocular concomitant medications will be summarized 
separately, and summaries will be displayed for the ITT set. Subjects with multiple medications in the 
same WHO drug dictionary class or preferred name will be counted only once for that respective WHO 
drug dictionary class or preferred name. 
13. Dosing Compliance and Treatment Exposure 
 
13.1 
Dosing Compliance 
A dose is considered a single 400 mg tablet. Subjects are instructed per protocol to administer a dose 
twice daily (i.e., once in the morning and once in the evening). Dosing compliance (% compliance) will 
be assessed by calculating the number of actual doses received and comparing that to the number of 
expected doses as follows: 
 
Number of Actual Doses Received 
Compliance (%) = 
x 100 
Number of Expected Doses 
 
The number of actual doses received will be calculated from the number of dispensed and returned 
tablets as recorded in the eCRF. The number of expected doses that will be used for calculating 
compliance will be calculated as {2x [date of last dose – date of first dose]} +1 for all subjects, regardless 
of study completion status. Overall compliance will also be categorized as compliant (≥75%) and non- 
compliant (<75%). 
Treatment compliance (%) will be summarized for the Safety set using continuous descriptive statistics. 
The compliance categories defined above will be summarized with counts and percentages. 
A subject listing of compliance will also be produced. 
 
13.2 
Treatment Exposure 
Extent of exposure will be calculated in days using the following: 


Protocol ALK4290-202 SAP, Version 1.0 
04 SEP 2018 
Confidential & Proprietary 
Page 16 of 29 
 
 
 
Extent of Exposure (days) = [Date of last dose – Date of first dose] + 1 
 
Extent of treatment exposure (days) and the total number of doses received for each subject exposed 
to IMP will be summarized with continuous descriptive statistics using the Safety set. A subject listing of 
treatment exposure will also be produced. 
14. Analysis of the Primary Endpoint 
The primary endpoint is the mean change from baseline (Visit 2 / Day 1) to end of treatment (Visit 8 / 
Day 43) in BCVA letter score of the study eye as measured by the ETDRS testing method using the 
Evaluable set. BCVA will be measured at the beginning of every study visit and change from baseline 
for each subject will be calculated as follow-up visit minus baseline visit. Quantitative summary statistics 
will be used to summarize the BCVA letter score and change from baseline at each visit. A two-tailed, 
one-sample t-test will be used to assess the mean change from baseline in BCVA letter score at each 
visit, in which the change from baseline BCVA letter score will be compared to a reference value of zero. 
The following SAS code will be used to run the one-sample t-test: 
PROC TTEST H0=0 ALPHA=0.20 DATA=INDATA; 
VAR BCVA_CHG; 
RUN; 
where 
 
- INDATA is the name of the input dataset; 
- BCVA_CHG is the change in BCVA from baseline to the follow-up visit. 
 
A mixed model accounting for repeated measures will also be used to analyze BCVA. This model will 
include the change from baseline in BCVA letter score as the response variable and baseline BCVA 
letter score, smoking status and visit as explanatory variables for adjustment. LS means for each visit 
will be calculated along with corresponding 95% CIs and p-values. SAS code to implement this repeated 
measures mixed model is as follows: 
PROC MIXED DATA=INDATA; 
CLASS SUBJID SMOKE VISIT; 
MODEL CHG = BASELINE SMOKE VISIT / DDFM = KR SOLUTION; 
REPEATED VISIT / SUBJECT=SUBJID TYPE=UN; 
LSMEANS VISIT / CL; 
RUN; 
where 
- INDATA is the name of the input dataset sorted by SUBJID and VISIT; 
- SUBJID is the subject ID number; 
- SMOKE is the subject’s smoking history (Never smoked, Ex-smoker, Currently smokes);

- VISIT is the visit at which the BCVA letter score was collected;
- CHG is the change from baseline in the BCVA letter score;
- BASELINE is the baseline BCVA letter score;
The Kenward-Roger method will be used to determine denominator degrees of freedom. An 
unstructured variance-covariance matrix will be used for the above repeated measures model. If the 
model does not converge using the unstructured matrix, the first order autoregressive structure and the 
compound symmetry structure will be employed, in that order. 
The above analyses will be repeated on the PP set as a sensitivity analysis. 
Additionally, the number of subjects with change from baseline in BCVA letter score for the following 
categories will be summarized with counts and percentages: 
•
>=15 letters;
•
>=14 and >=10 letters;
•
>=9 and >= 5 letters;
•
>=4 and >= -4 letters;
•
>= -5 and >= -9 letters;
•
>= -10 and >= -14 letters;
•
<= -15 letters.
BCVA results will also be presented in a data listing. BCVA results in the fellow eye are not included in 
the analyses but will be included in the listings. BCVA will also be summarized by visit using box plots. 
15. Analysis of the Secondary Endpoints
The analyses for secondary endpoints (incidence, seriousness and severity of AEs) will be discussed in
the next section as part of the safety analyses. There is no secondary efficacy endpoint for the study.
16. Safety Analyses
Safety will be assessed for the following endpoints using the Safety set:
•
Incidence, seriousness, and severity of AEs;
•
Observed slit-lamp biomicroscopy values;
•
Observed intraocular pressure (IOP) values;
•
Changes from baseline in clinical laboratory values;
•
Changes from baseline in physical examination;
•

Other safety endpoints including slit-lamp biomicroscopy, IOP, clinical laboratory values, physical 
examination, and vital signs will be summarized using descriptive statistics. Changes or shifts from 
baseline will also be summarized where appropriate. Assessments performed by eye (study eye and 
fellow eye) will be summarized separately. No statistical inferential testing will be performed for safety 
variables. 
16.1 
Adverse Events 
AEs are defined as any untoward medical occurrence associated with the use of an IMP in humans, 
whether or not considered IMP-related. All AEs, serious and non-serious, occurring during the 
course of the clinical trial (i.e., from signing the informed consent through the follow-up period) will 
be collected, documented, and reported. All AEs that occur or worsen on or after the first use of 
IMP will be considered as treatment-emergent AEs (TEAE). Reported AEs that begin prior to the 
first dose of IMP are classified as non-TEAEs; these will only be included in subject listings and not 
included in summary tables. 
When reporting an AE, the event description should use the best matching terminology describing the 
event as found in the Common Terminology Criteria for Adverse Events (CTCAE v4.03). Standardized 
terms from the CTCAE will be used to categorize events for reporting to regulatory authorities using the 
Medical Dictionary for Regulatory Activities (MedDRA, v. 21.0). 
The severity of all reported AEs are graded by the investigator into one of the following five (5) CTCAE 
categories: 
•
Grade 1 (Mild)
•
Grade 2 (Moderate)
•
Grade 3 (Severe)
•
Grade 4 (Life-Threatening)
•
Grade 5 (Death)
The relatedness of IMP to AE will be classified as definite, possibly, or unrelated. Documentation of AEs 
will include start date, end date, seriousness, severity, relatedness, whether or not medication was 
required, outcome, and action taken with the study agent. 
A serious adverse event (SAE) is defined for this protocol as any AE that meets one or more of the 
following criteria: 
•
A death (CTCAE Grade 5 event) occurring during the study, whether or not considered
treatment-related;
•
A life-threatening event (CTCAE Grade 4);

•
An event requiring inpatient hospitalization or prolonged hospitalization due to the
adverse event;
•
An adverse event resulting in a significant, persistent, or permanent change, impairment,
damage or disruption in the participant’s body function or structure, physical activities or
quality of life;
•
An event that otherwise required a medical or surgical intervention to preclude
permanent impairment or damage (excluding unrelated elective or cosmetic procedures).
An AE of special interest (AESI) is defined for this protocol as any the following outcomes: 
•
Hepatic injury defined by the following alterations of liver parameters:
o
For subjects with normal liver function at baseline an elevation of aspartate
aminotransferase (AST) and/or alanine aminotransferase (ALT) ≥ 3-fold the upper
limit of normal (ULN) combined with an elevation of total bilirubin ≥ 2-fold the ULN
measured in the same blood draw sample;
•
Abrupt decrease of BCVA (> 15 letters lost from baseline);
•
QTc interval prolongation (> +50 ms from baseline and > 450 ms).
An overall tabular summary of TEAEs will be presented that includes the number and percentage of 
subjects who experienced at least one TEAE. These summaries will also include breakdowns of TEAEs 
further categorized as ocular or non-ocular, and within these categories as drug-related TEAEs, TEAEs 
with CTCAE Grade 3/4/5, drug-related TEAEs with CTCAE Grade 3/4/5, TEAEs with an outcome of 
death, serious TEAEs, drug-related serious TEAEs, TEAEs leading to discontinuation of IMP and drug- 
related TEAEs leading to discontinuation of IMP. 
Furthermore, the number and percentage of subjects with TEAEs by SOC and PT; by SOC, PT and 
maximal severity; by SOC and PT for TEAEs; by SOC and PT for SAEs; and by SOC and PT for TEAEs 
leading to subject withdrawal will be presented. Separate summaries will be provided for ocular and 
non-ocular TEAEs (including systemic). Adverse events of special interest will also be summarized by 
SOC and PT. These summaries by SOC and PT will be at the subject level. If a subject reports the 
same PT multiple times within the same SOC, that PT will only be counted once within that SOC. As 
with the PT, if a subject reports multiple conditions within the same SOC, that SOC will only be counted 
once. 
All AEs (including non-TEAEs) will also be presented in subject listings. 
16.2 
Slit-Lamp Biomicroscopy Examination 
Slit-lamp biomicroscopy examinations will be conducted on both eyes at all scheduled visits. The slit- 
lamp findings will include examinations of the cornea, conjunctiva, anterior chamber, iris/pupil, lens and

normal or abnormal. Abnormal findings will be further classified as not clinically significant (NCS) or 
clinically significant (CS). All clinically significant values will be recorded as AEs in the eCRF and 
followed until resolution. Once resolved, the AE eCRF page(s) will be updated 
Slit-lamp findings will be summarized by visit, for the study eye and fellow eye separately, using 
qualitative summary statistics (frequency counts and percentages). Percentages will be based on the 
number of subjects with non-missing values at a given visit. 
A shift table will show changes from baseline Visit 2 (Day 1) to all observations at later study visits. The 
data for slit-lamp biomicroscopy examinations will be presented in a listing. 
16.3

All safety laboratory measurements will be performed at all scheduled visits by a central laboratory 
(except serology which is evaluated at screening only) . Investigators will get guidance and instructions 
on laboratory sampling and processing through a separate Lab Manual provided by the central 
laboratory. 
The investigator is responsible for determining and documenting if out of range laboratory values are 
clinically significant or not. All clinically significant values will be recorded as AEs in the eCRF and 
followed until resolution. Once resolved, the AE eCRF page(s) will be updated. 
Continuous biochemistry, hematology, and coagulation assessments will be summarized by visit and 
changes from baseline using quantitative summary statistics. The data for biochemistry and hematology 
will also be presented in listings. 
Serology and urinalysis will be listed with collection information, and clinically significant findings, but no 
tabular summaries will be produced. 
All laboratory values will be presented using conventional units. 
16.5 
Electrocardiogram (ECG) 
ECGs will be measured at screening Visit 1, Visit 3, Visit 6, and Visit 8/EOT, and graded as normal or 
abnormal. Abnormal findings or changes from baseline will be further classified as not clinically 
significant (NCS) or clinically significant (CS).In the event abnormal ECG results requires additional 
follow up, ECGs may be performed at unscheduled visits or at a study visit that an ECG is not required 
per protocol. ECG data performed outside of the protocol specified time points will be captured in the 
EDC on an “Unscheduled Visit” eCRF and mapped to the nearest scheduled visit as defined in Section 
9.3. ECG grades and shift from baseline will be summarized with counts and percentages for each visit 
for the Safety set. All clinically significant findings will be recorded as AEs in the eCRF and followed
