Study Summary 
Title:   
A Phase 1 Open-Label, Dose Escalation Study to Assess the Safety and 
Tolerability of Intravitreal ONL1204 in Patients with Macula-off, 
Rhegmatogenous Retinal Detachment. 
Rationale:   
The purpose of this study is to evaluate the safety and tolerability of 
ONL1204 in Patients with Macula-off, Rhegmatogenous Retinal 
Detachment (RRD).  RRD is an acute and serious vision threatening 
condition in which a tear in the retina, typically resulting from a 
vitreous detachment, allows liquefied vitreous to enter the subretinal 
space, detaching the photoreceptor (PR) layer of the neurosensory 
retina from the retinal pigment epithelium (RPE).  As the RPE is the 
principal source of nutritional support for the PR layer, the 
photoreceptors begin a cascade of inflammation and cell death.  
Photoreceptor cell death is the primary mechanism of vision loss after 
retinal detachment.   
ONL1204 is a first-in-class inhibitor of Fragment Apoptosis Stimulator 
receptor (Fas)-mediated cell death.  ONL1204 has demonstrated 
protection of multiple retinal cell types in numerous preclinical models 
of acute ocular injury. 
This will be a first-in-human (FIH) study to evaluate safety and 
tolerability of a single-dose of ONL1204 in patients with macula-off 
RRD.   
The standard of care for surgical repair of macula-off RRD is 
reattachment surgery (typically by vitrectomy with or without scleral 
buckling) within 7 days of the macula detaching.  Patients will receive 
a single intravitreal injection upon enrollment in the study on the day of 
diagnosis.  The vitrectomy procedure will remove the bulk of drug 
remaining in the vitreous.  
Target 
Population: 
Patients who present between 1 week (7 days) to 4 weeks (28 days) of 
a macula-off RRD (based on patient-reported history of loss of central 
vision) for whom standard retinal reattachment surgery by means of a 
pars plana vitrectomy and gas tamponade is indicated.

Number of 
Patients: 
Approximately 16 patients will be enrolled in this study. 
• 4 ascending dose groups; 4 active. The first patient in each dose 
group will be observed for at least 14 days post-surgery (through 
visit 6) prior to enrolling the remainder of the patients in that dose 
group. 
• Patients may be replaced who do not receive an injection of study 
medication, or for discontinuing from the study for reasons 
unrelated to treatment before completing Visit 4.  All patients 
receiving injection of study drug will be followed for safety and 
tolerability. 
Study Visits 
There is a minimum of 8 scheduled study visits: 
• Visit 1:  Day 1 (baseline/drug injection) 
• Visit 2:  Day 2 (1 day post-injection*)  
• Visit 3:  Day of Vitrectomy (3 + days post-injection in accordance 
with standard of care vitrectomy)  
• Visit 4:  Postoperative visit (1 day post-surgery)  
• Visit 5: Post-operative visit (2 weeks post-surgery and clearance of 
sentinel patient/cohort (14 days +4 days post-surgery)) 
• Visit 6:  Week 6 (±7 days) 
• Visit 7:  Week 9 (±7 days) 
• Visit 8:  Week 24/Exit (±14 days) 
*additional visits between visit 2 and 3 per investigator’s discretion 
Objectives: 
To evaluate safety and tolerability of a single intravitreal injection of 
ONL1204 in patients with macula-off, RRD. 
Study Design: 
This is a single-injection, open-label dose escalation study. 
Primary 
Objective: 
 
The primary objective will be to determine the Maximum Tolerated 
Dose (MTD) of ONL1204 and select doses for Phase 2.  Determination 
of this will be through review of the parameters measured in the 
Schedule of Assessments, as well as adverse event (AE) reports.

Objective: 
During the study, ocular fluid samples will be collected at the time of 
study drug injection and at the time of vitrectomy.  These samples will 
be used for pharmacokinetic and pharmacodynamic analyses, the 
results of which will help inform the dose selection for the Phase 2 
trial(s).

STUDY SCHEMATIC 
Figure 1 
Study Schematic 
16 patients will be enrolled and treated, starting with the lowest dose, Cohort 1.  The first 
patient in each cohort will be observed for at least 14 days post surgery (through Visit 5) 
before the rest of the cohort can be enrolled. The safety review committee will review the 
data prior to clearing the sentinel patient and enrolling the remainder of the cohort. After 
all 4 patients in a cohort have completed Visit 5, the safety review committee will review 
available safety data to determine if dose limiting toxicity exists that prohibits enrolling 
the next higher dose cohort. The respective IRB’s will be informed of the outcome of the 
SRC meetings. 
If there are no safety concerns, the next cohort will start treatment.  
 
*Patients may be replaced who do not receive an injection of study medication, or for discontinuing from 
the study for reasons unrelated to treatment before completing Visit 4.

1 INTRODUCTION AND RATIONALE 
1.1 
Background 
Retinal detachment is an ocular condition that involves the retina being separated from 
the underlying layer of cells, including the retinal pigment epithelium (RPE).  This 
separation often results in the death of key retinal cells, including photoreceptors, which 
can lead to vision impairment and/or loss. 
The most prevalent form of retinal detachment is rhegmatogenous retinal detachment 
(RRD), which involves a tear in the retina.  While standard of care (SOC) surgical 
reattachment results in high rates of anatomic surgical success, in many cases, especially 
those involving the macula (central vision), patients have significant loss of vision even 
with successful surgery.  In part, this is due to the fact that photoreceptors begin to die 
once the detachment takes place and cell death continues up to the time of surgery 
(sometimes as long as a week after the detachment). 
ONL Therapeutics (ONL) is developing ONL1204, a first-in-class inhibitor of Fragment 
Apoptosis Stimulator (Fas)-mediated cell death that has demonstrated protection of 
multiple retinal cell types in numerous preclinical models of acute ocular injury.  The 
development of ONL1204 addresses an unmet medical need:  the prevention of vision 
loss in patients suffering from deterioration of visual function after acute retinal injury 
such as from macula-off RRD.   
Refer to the Investigator’s Brochure (IB) for more information. 
1.2 
ONL1204 
The investigational study agent is ONL1204 Ophthalmic Solution.  The drug product 
consists of the drug substance ONL1204 dissolved in a vehicle consisting of purified 
water containing mannitol, poloxamer 407, and glacial acetic acid.  The pH is adjusted to 
pH 4.5 by sodium hydroxide solution.  ONL1204 Ophthalmic Solution is provided as a 
sterile liquid in single-use vials stored at 2 to 8°C (36 to 46°F) and is administered by 
intravitreal (IVT) injection.  
1.2.1 
Preclinical Experience 
The sponsor has observed a pharmacological effect of ONL1204 in preventing Fas-
mediated cell death in 3 models of acute retinal injury – namely the rat retinal detachment 
model, the rabbit sodium iodate model, and the mouse microbead model of glaucoma.   
ONL1204 disrupts the binding of human Fas ligand to the human Fas receptor in vitro, 
while ONL1204 analog Met12 has been shown to bind to Fas receptor and prevent Fas

ligand activated cell death in human Jurkat cells in vitro. The available nonclinical data 
from completed studies indicates that ONL1204 has efficacy towards the Fas ocular 
receptor based on the in vitro inhibition of caspase activity with a potency of 0.4 to 
0.45 µM.   
In vivo, administration of ONL1204 by IVT injection at doses of up to 10 µg/eye resulted 
in a reduction of terminal deoxynucleotidyl transferase (dUTP) nick end labeling 
(TUNEL) positive staining cells in a rat model of retinal detachment.  There was an 
approximate 75% reduction in the percent positive staining cells across the dose range 
examined.  The minimal, maximally effective dose for ONL1204 was 0.1 to 0.3 µg.  
Pharmacological activity towards the Fas receptor did not differ with different 
formulations of ONL1204, though poloxamer formulations appeared to have preferable 
pharmaceutical properties. 
To study the potential role of ONL1204 in geographic atrophy, ONL conducted a sodium 
iodate study in rabbits.  Sodium iodate is highly toxic to the retinal pigment epithelium 
and is a commonly used model for geographic atrophy.  IVT injection of ONL1204 at 0.1 
or 0.025 mg 4 days prior to sodium iodate injection preserved the RPE, suggesting that 
ONL1204 may also be useful in treating geographic atrophy. 
In a microbead model of glaucoma, data suggest that ONL1204 can also inhibit the 
production of macrophage and Receptor Interacting Protein Kinase 3 (RIPK3)-dependent 
inflammasome activation, which exacerbates retinal detachment-induced photoreceptor 
cell death through the release of interleukin (IL)-1β. 
In pharmacokinetic (PK) studies, ONL1204 is distributed to the retina, iris-ciliary body 
(ICB), and vitreous with IVT injection.  Following injection, the drug is slowly 
eliminated from these ocular structures.  The prolonged elimination of the drug is 
considered clinically meaningful for use in RRD where patients may not undergo surgical 
repair for several days following injection.  However, the clinical plan for retinal 
detachment includes a vitrectomy within 7 days after injection, which will remove the 
bulk of the drug remaining in the vitreous.   
Based on the pharmacodynamic (PD) and preliminary toxicity data, ONL has chosen the 
4.5% mannitol, 0.4% poloxamer 407, and 10 mM acetic acid (pH 4.5) formulation to be 
used in further development of ONL1204.  There was acceptable (minimal to mild) 
ocular toxicity in the rabbit with this formulation and the current drug formulation of 
ONL1204.  Moreover, ONL1204 was undetectable in the rabbit plasma (lower limit of 
quantification [LLOQ]:  1 ng/mL) following a total dose equal to the planned top dose in 
humans resulting in no systemic toxicity after full histopathologic examination of all 
major organs.   
Good Laboratory Practice (GLP) compliant toxicity studies using this formulation of 
ONL1204 are completed.

Preclinical data thus far indicate the intended clinical formulation at the top dose (200 µg) 
to be used in clinical trials should have an acceptable safety profile over a 14-day period 
following IVT injection.  
Refer to the IB for detailed information on the nonclinical studies conducted using 
ONL1204.  
1.2.2 
Clinical Experience 
ONL1204 has not been previously studied in humans; this will be the first-in-human 
(FIH) study of ONL1204.  Since there are no clinical data for ONL1204, the observed 
findings in nonclinical studies with ONL1204 will guide the monitoring in this study. 
1.3 
Study Rationale 
The purpose of this Phase 1 study is to collect safety information of ONL1204 in patients, 
establish a safe dose range, and collect PK and ocular PD information.   
The study population will be patients with newly diagnosed macula-off RRD.  Patients 
with RRD have an acute and serious vision threatening condition where a tear in the 
retina, typically resulting from a vitreous detachment, allows liquefied vitreous to enter 
the subretinal space, thereby detaching the photoreceptor (PR) layer of the neurosensory 
retina from the RPE.  As the RPE is the principal source of nutritional support for the PR 
layer, the photoreceptors begin a cascade of inflammation and cell death.  Nonclinical 
data on ONL1204 suggest that ONL1204 may inhibit the cell death pathway in RRD, 
preventing vision loss in patients suffering from acute retinal injury such as from macula-
off RRD. 
In clinical use, ONL1204 will be delivered to patients by intravitreal injection at the time 
of diagnosis to protect photoreceptors from death until surgery can be completed, with 
the hope of improving positive patient outcomes from already anatomically successful 
surgeries.  
1.3.1 
Rationale for the Proposed Doses 
As described in 1.2.1 the minimal, maximally effective dose in the rat model of retinal 
detachment delivered by an IVT injection was 0.1 to 0.3 ug per eye. Based on scaling of 
this MMED from the rat eye to the human eye, the calculation is as follows:  the vitreous 
volume of a rat eye is 13-20 microliters, while that of the human is approximately 4,400 
microliters (a factor of 220-338x).  With the MMED being estimated at 0.1 micrograms 
in the rat, this scales to a dose of 22-34 micrograms in the human eye. This dose 
escalation study starts at a 25 microgram dose and increases to 50 micrograms in the next

cohort, followed by a 100 microgram cohort and 200 micrograms in last dose escalation 
cohort. 
As stated, the maximum dose planned for this trial is 200 µg.  In animal studies, using 
Dutch Belted rabbits, this dose was intravitreally injected into one eye while the 
contralateral eye served as an untreated control.  The findings from this study suggested 
the current formulation at the top dose (200 µg) to be used in GLP-compliant nonclinical 
studies and in clinical trials should have an acceptable safety profile over a 14-day period 
following IVT injection, especially given that the allometrically scaled dose in the rabbit 
is approximately 2-fold greater than the planned high dose intended for this initial 
clinical trial.  
The following doses will be evaluated:  25 µg, 50 µg, 100 µg and 200 µg ONL1204.  
ONL1204 will be administered as a sterile liquid by intravitreal injection. Patients 
randomized to receive the treatment will be given one injection of the drug.  
1.3.2 
Rationale for Pharmacokinetic testing 
Systemic PK will be evaluated following IVT administration of ONL1204.  ONL1204 is 
not expected to be detected in the plasma and this will be confirmed in this study, which 
will preclude additional systemic PK evaluation in future studies. 
ONL1204 will also be measured in the vitreous samples taken at the time of the 
vitrectomy to evaluate clearance of the drug from the vitreous.   
1.3.3 
Rationale for Vitreous Tap and Pharmacodynamic 
Analysis 
A vitreous tap will be performed at the time of diagnosis/IVT injection of drug, and an 
undiluted vitreous sample as well as aqueous sample will be taken at time of surgery.  
This will allow for assessment of the cytokine profile before and several days after 
administration of ONL1204.  This will allow for the potential identification of a 
biomarker for proof of principle of target engagement, via analysis of cytokines and other 
potential molecular biomarkers that impact visual acuity after surgical repair of retinal 
detachment.  The described procedures are routine for retinal surgeons, with the risk of 
endophthalmitis thought to be similar to that of IVT injections (1 in 2000-3000 patients).

1.4 
Potential Risks and Benefits 
1.4.1 
Potential Risks of Study Product 
There could be a risk of an adverse reaction to the ONL1204 drug product or vehicle.   
Although unlikely, potential risks include: 
• Intraocular inflammation 
• Elevated intraocular pressure 
• Visual loss 
• Retinal cell death 
• Less favorable surgical outcome following repair 
• Systemic adverse reaction 
Patients will be carefully monitored after vitreous tap and intravitreal injection of 
ONL1204, with multiple post procedure visits with the investigator.  At these visits, 
visual acuity will be assessed, intraocular pressure measured, the eyes examined 
according to assessments listed in 6.4.2, and any adverse events (AEs) reviewed.  Based 
on these assessments, additional visits may be scheduled at investigator discretion.  This 
close monitoring for inflammation, infection, and changes in vision will help reduce 
associated risks.   
There is a remote risk of systemic adverse reaction in response to intravitreal injection of 
ONL1204.  This risk is greatly mitigated by the study molecule’s long half-life in 
vitreous (most drug stays in the eye until surgery) and extremely short half-life in plasma.  
Patients will undergo clinical blood testing, with assessment of complete blood count, 
renal function tests and hepatic function tests to monitor for any such systemic adverse 
reactions. 
1.4.2 
Potential Risk to Fetal Development 
Potential risk to fetal development is unknown.  Therefore, all female patients of 
childbearing potential must have a negative pregnancy test before being enrolled in this 
study, and all participants must use adequate contraceptive precautions during the study, 
Section 6.4.9.

1.4.3 Potential Risks of Intravitreal Injection, Vitreous Tap, Pupil 
Dilation and Blood Draw 
Intravitreal injection and vitreous tap are common procedures, but both do carry the risk 
of possible adverse reaction including: 
• Infection  
• Inflammation 
• Irritation 
• Pain 
• Bleeding 
• Increased intraocular pressure 
• Retinal holes/retinal tears 
• Retinal detachments 
• Cataract 
• Worsened vision/vision loss/loss of eye 
• Corneal abrasion 
 
Pupil dilation is also a common procedure during an eye exam but carries a risk of 
possible adverse reaction including: 
• Redness 
• Stinging/discomfort 
• Allergic reactions 
• Sensitivity to light 
• Blurred vision 
 
The procedure of blood draw, even though a common procedure carries the risk of 
possible adverse reactions such as: 
• Pain/discomfort 
• Bruising 
• Infection 
• Fainting

Care will be taken to reduce the risk of infection at the time of the tap and intravitreal 
injection through antisepsis, sterile technique and expert care as these procedures will be 
performed by experienced retinal surgeons. 
1.4.4 
Potential Risks of Vitrectomy 
Any surgical intervention has risk, and the risks associated with retinal detachment repair 
are not insignificant.  Patients in this trial, however, will receive the same retinal surgery 
whether they participate in this trial or not so retinal surgery is not a study specific risk. 
Potential participants in this study have been diagnosed with macula-off, rhegmatogenous 
retinal detachment and will be undergoing standard retinal reattachment surgery by 
means of a pars plana vitrectomy (with or without scleral buckle) and gas tamponade. 
The surgeon will fully discuss the possible risks of this surgery with the patient prior to 
the surgery.  
1.4.5 
Potential Benefit of Study Product 
There is a possibility that ONL1204 could prevent photoreceptor cell death, ultimately 
resulting in better visual acuity in patients treated with ONL1204; however, this is not 
known. 
2 
STUDY OBJECTIVE 
2.1 
Primary Objective 
The primary objective will be to determine the Maximum Tolerated Dose (MTD) of 
ONL1204 and select doses for Phase 2.  Determination of this will be through review of 
the parameters measured in the Schedule of Assessments, as well as adverse event (AE) 
reports.  
2.2 
Exploratory Objective 
During the study, ocular fluid samples will be collected at the time of study drug injection 
and at the time of vitrectomy.  These samples will be used for pharmacokinetic and 
pharmacodynamic analyses, the results of which will help inform the dose selection for 
the Phase 2 trial(s).

Exploratory Endpoints 
The exploratory endpoints will be the pharmacokinetic and pharmacodynamic analyses 
performed in this study, including: 
• Measurement of ONL1204 drug levels in plasma and vitreous fluid for PK analysis 
• Cytokine and other potential molecular biomarker measurement in aqueous and 
vitreous samples, taken by vitreous tap, and at vitrectomy 
4 STUDY DESIGN 
This proposed study is a single-injection, open-label, dose escalation study to assess the 
use of intravitreal ONL1204 in patients with macula-off RRD.  Approximately 
16 patients with RDD will be enrolled.  The expected duration of patient participation in 
the study is approximately 24 weeks (treatment, then 24 weeks of follow-up).  
4.1 
Overview of Study Design 
Sixteen patients will be enrolled in 4 ascending dose groups.   
After signing informed consent and meeting all eligibility criteria, patients will undergo a 
vitreous tap for cytokine and other potential molecular biomarker analysis followed by a 
single intravitreal injection of ONL1204.  This will occur on the day of diagnosis (Day 
1).  Safety visits will be conducted 1 day post-injection and per Investigator’s discretion 
until Visit 3.  At Visit 3 (3+ days post-injection, in accordance with standard of care) 
patients will undergo surgical repair of their retinal detachment with vitrectomy (with or 
without scleral buckling) and gas or oil tamponade. At the time of surgery, an undiluted 
vitreous sample will be collected for pharmacokinetic and pharmacodynamics analyses, 
and an aqueous sample will be collected for pharmacodynamic analysis. Additional 
safety visits will be conducted 1 day post-surgery, 14 (+4 days) days post-surgery, 
Weeks 6, 9 (±7 days each), and Week 24 (±14 days; study exit).   
As this is a first-in-human safety study of ONL1204, the first patient in the first cohort 
will receive the lowest dose of ONL1204. After this patient completes Visit 5 (14 
+4 days post-surgery) and a safety review committee reviews the data, the remainder of 
the patients in that cohort will be enrolled.  After all patients in the cohort have 
completed Visit 5, the SRC will review the available safety data to determine if dose

limiting toxicity exists that prohibits enrolling the next higher dose cohort.  This process 
will be repeated until escalating to the top dose.   
The following doses will be evaluated:  25 µg, 50 µg, 100 µg, and 200 µg ONL1204.  
ONL1204 is available in vials with concentrations of 0.5 mg/mL and 2 mg/mL. 
Therefore, a volume of 0.05 or 0.1 mL will be injected into the study eye. 
Patient participation will be approximately 24 weeks (6 months):  a single injection 
treatment and 24 weeks of follow-up.

This is an open-label study and all patients will be receiving study drug.   
4.2 
Dose Limiting Criteria and Maximum Tolerated Dose  
4.2.1 
Dose Limiting Criteria 
Dose limiting toxicity, if observed, will be declared by the SRC, based on their review of 
the relevant clinical information.  
Determination of dose limiting toxicity will include consideration of the following 
events: 
1. Ocular inflammation increases by 2 units from pre-injection on the Standardization of 
Uveitis Nomenclature (SUN) grading scale for aqueous cell or vitreous haze, 
secondary to inflammation and not the drug formulation itself, identified post-
injection of ONL1204 and prior to retinal reattachment surgery; 
2. Sustained elevation of IOP characterized as > 30 mmHg for 3 consecutive days, post-
injection of ONL1204 and prior to retinal reattachment surgery, despite 
pharmacologic therapy; 
3. Reduction in visual acuity from baseline after injection of ONL1204 and prior to 
retinal reattachment surgery, that in the opinion of the investigator is likely due to the 
investigational product and results in a: 
a) Decrease in visual acuity from 20/200 or 20/400 to light perception without 
progression of the underlying retinal detachment; or 
b) Decrease in visual acuity from baseline to no light perception.  
4. Any serious adverse event (SAE) that occurs within the first 14 days following 
ONL1204 injection that, in the opinion of the investigator, is related to ONL1204.

4.2.2 
Dose Escalation Decisions 
Dose escalation decisions include the following: 
1. To begin enrolling the next cohort at the planned dose or an adjusted dose. 
2. To delay opening the next cohort in order to collect additional safety on the current 
cohort, or to enrol additional patients in the current cohort if safety concerns are 
identified. 
3. To stop the cohort escalation if unacceptable toxicities are noted. 
If, in the opinion of SRC, dose limiting toxicity is reached, the previous, lower dose will 
be considered the Maximum Tolerated Dose (MTD).

6.4.9 
Contraception and Pregnancy Avoidance Measures 
Due to the unknown effects of ONL1204 on sperm and the developing fetus, female 
patients of childbearing potential (i.e., non-sterilized, premenopausal female patients) and 
male patients must agree to use double barrier contraception methods throughout the 
study and for at least 30 days after the dose of study drug. Double barrier contraception is 
defined as a condom and one other form of the following: a) Birth control pills (The Pill), 
b) Depot or injectable birth control, c) IUD (Intrauterine Device), d) Birth control patch 
(e.g. Ortho Evra), e) NuvaRingR, f) Documented evidence of surgical sterilization at least 
6 months prior to the study drug injection, i.e., tubal ligation or hysterectomy for women 
or vasectomy for men. Rhythm methods during the study and for at least 30 days after the 
dose of study drug will not be acceptable. 
 
Male patients must not donate sperm for at least 24 weeks post-dose of the last study 
treatment. Male partners of female patients and female partners of male patients must 
also use contraception, if they are of childbearing potential.  
6.4.10 
Clinical Laboratory Tests 
The following clinical laboratory tests will be performed, according to the Schedule of 
Assessments (Table 4-1): 
• Complete blood count, including:  white blood cell (WBC) count with differential,

dispensed to the patients, will be provided and kept at the study sites.  The sponsor CRA 
will reconcile the study drug for that cohort. 
Proper drug accountability includes, but is not limited to: 
• Monitoring expiration dates if expiry date or retest date is provided to the 
Investigator.  
• Verifying that actual inventory matches documented inventory.  
• Verifying that the master drug log is completed for all study medication received at 
the site and that all required fields are complete, accurate, and legible.  
• Review of temperature log, and assure that the study medication is stored under 
locked, access-controlled conditions.  
• Verifying the patient individual drug accountability log is completed for each patient 
and that all required fields (units dispensed, returned, used, etc.) are complete, 
accurate, and legible.

If any dispensing errors or discrepancies are discovered, the sponsor must be notified 
immediately.  At the end of the study, the Investigator will retain all the original 
documentation regarding clinical study material accountability, return, and/or destruction, 
and copies will be sent to the sponsor. 
7.10 Compliance 
Study drug will be administered only to eligible patients under the supervision of the 
principal investigator or identified sub-investigator(s).  The appropriate study personnel 
will maintain records of study drug receipt and dispensing. 
7.11 Documenting Adverse Events 
All AEs spontaneously reported by the patient and/or in response to an open question 
from study personnel or revealed by observation or other diagnostic procedures will be 
recorded on the appropriate page of the eCRF.  Any clinically relevant deterioration in 
laboratory assessments or other clinical finding is considered an AE.  This includes 
changes in ocular assessments, such as a decrease in visual acuity or a persistent increase 
in IOP.  When possible, signs and symptoms indicating a common underlying pathology 
should be noted as one comprehensive event. 
8 
ADVERSE EVENTS 
8.1 
Pretreatment Event Definition 
A pretreatment event is any untoward medical occurrence before administration of any 
study medication or study procedure in a patient or subject who has signed informed 
consent to participate in a study; it does not necessarily have to have a causal relationship 
with study participation. 
8.2 
Adverse Event Definition 
AE means any untoward medical occurrence in a patient or subject administered a 
pharmaceutical product or undergoing a study procedure; the untoward medical 
occurrence does not necessarily have a causal relationship with this treatment.  An AE 
can therefore be any unfavorable and unintended sign (including an abnormal laboratory 
finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product or study procedure whether or not it is related to the medicinal 
product or study procedure.  This includes any newly occurring event, or a previous 
condition that has increased in severity or frequency since the administration of study 
drug or study procedure.

ONL1204 
Page 38 of 52 
 
 
 
8.3 
Assessment of Intensity 
For both serious and non-serious AEs, the investigator must determine both the intensity 
of the event and the relationship of the event to study drug administration.  For serious 
pretreatment events, the investigator must determine both the intensity of the event and 
the relationship of the event to study procedures. 
8.4 
Assessment of Causality 
Relationship to study drug administration will be determined by the investigator with the 
following options to choose from:  Definitely related – Probably related – Possibly 
related – Unlikely/Remotely related – Not related – Unknown.  
8.5 
Clinical Laboratory Changes 
Blood samples for clinical laboratory evaluation, and urine for pregnancy test will be 
obtained as specified in the Schedule of Assessments (Table 4-1).  Any clinically 
significant or concerning laboratory results will be documented as an adverse event.   
8.6 
Adverse Event Follow-up 
All AEs, both non-serious and serious, will be monitored throughout the study until the 
exit visit, or 30 days after use of the study drug, whichever is longer.  Serious AEs will be 
followed to resolution or stabilization or until 30 days after subject completes the study. 
8.7 
Serious Adverse Events 
8.8 
Serious Adverse Event Definition  
A SAE is any event that meets any of the following criteria: 
• Death 
• Life-threatening 
• Inpatient hospitalization or prolongation of existing hospitalization 
• Persistent or significant disability/incapacity 
• Congenital anomaly/birth defect in the offspring of a patient who received ONL1204 
• Other:  Important medical events that may not result in death, be life-threatening, or 
require hospitalization, may be considered an SAE when, based upon appropriate 
medical judgment, they may jeopardize the patient and may require medical or

surgical intervention to prevent one of the outcomes listed in this definition. 
Examples of such events are: 
o Intensive treatment in an emergency room or at home for allergic bronchospasm 
o Blood dyscrasias or convulsions that do not result in inpatient hospitalization 
o Development of drug dependency or drug abuse 
o Study specific:  No study specific serious adverse events are expected 
Definition of Terms 
Life-threatening:  An AE is life-threatening if the patient was at immediate risk of death 
from the event as it occurred; i.e., it does not include a reaction that if it had occurred in a 
more serious form might have caused death.  For example, drug induced hepatitis that 
resolved without evidence of hepatic failure would not be considered life-threatening 
even though drug induced hepatitis can be fatal. 
Hospitalization:  AEs requiring overnight hospitalization should be considered SAEs.  
Hospitalization for elective surgery or routine clinical procedures that are not the result of 
AE (e.g., elective surgery for a pre-existing condition that has not worsened) need not be 
considered AEs or SAEs.  If anything untoward is reported during the procedure, that 
occurrence must be reported as an AE, either 'serious' or 'non-serious' according to the 
usual criteria. 
In general, hospitalization signifies that the patient 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.  When in doubt as to whether 'hospitalization' occurred or was necessary, the AE 
should be considered serious. 
Disability/incapacitating:  An AE is incapacitating or disabling if the experience results in 
a substantial and/or permanent disruption of the patient's ability to carry out normal life 
functions. 
8.9 
Reporting Serious Adverse Events 
Regardless of causality, upon signing the ICF, SAEs and serious pretreatment events 
must be reported by the investigator to the medical monitor and contract research 
organization (CRO) (contact information provided below), and if required, the 
investigator’s own Human Research Ethics Committee (HREC).  This should be done by 
faxing the SAE Form within 24 hours after becoming aware of the event.  The SAE Form 
will be provided to each clinical study site.  SAE report information must be consistent 
with the data provided on the eCRF.

9.1.3.2 
Ocular PK Population 
The ocular PK Population will comprise all patients in the Safety Population who provide 
adequate ocular PK samples to calculate the PK parameters.  Patients with protocol 
violations will be assessed on a patient-by-patient basis for inclusion in the ocular PK 
Population.  The PK analysis will be conducted using the ocular PK Population. 
For the pharmacokinetic data, per cohort and per protocol analyses will be performed.  
Each cohort population is defined as all patients within a dose cohort who received their 
assigned treatment and includes all those with no major protocol deviations. The per 
protocol population is defined as all patients who received their assigned treatment and 
includes all those with no major protocol deviations.  These populations will be 
determined well before database lock.  If patients withdraw from the study, their plasma 
concentration data may be included in the pharmacokinetic analysis provided there are no 
significant protocol noncompliance issues. 
9.2 
Study Endpoints 
9.2.1 
Primary Endpoints 
The primary endpoints will be the safety profile demonstrated in this study, including: 
• Adverse event reporting.  AEs will be split into study eye, non-study (fellow) eye, 
and systemic events 
• Clinical evaluations including BCVA 
• Clinical laboratory evaluations 
9.2.2 
Exploratory Endpoints 
• Measurement of ONL1204 drug levels in plasma and vitreous for PK analysis 
• Cytokine and other potential molecular biomarker measurement in aqueous and 
vitreous samples, taken by vitreous tap, and at vitrectomy. 
9.3 
Statistical Methods 
A statistical analysis plan will be developed and finalized before database lock and will 
describe the patient populations to be included in the analyses and procedures for 
accounting for missing, unused, and spurious data.  This section is a summary of the 
planned statistical analyses of the primary, secondary, and exploratory endpoints. 
In general, continuous variables will be summarized by descriptive statistics including 
sample size, mean, standard deviation, median, minimum, and maximum.  Geometric

mean and CV% will be presented for PK parameters.  Categorical variables will be 
summarized by frequency and percentage.  Data for ONL1204 treated patients will be 
summarized at each time point by cohort.   
9.3.1 
Safety Analyses 
All safety analyses will be based on the Safety Population.  Safety will be assessed 
through adverse event reporting, clinical evaluations including BCVA, ophthalmic 
imaging, and clinical laboratory evaluation. 
9.3.1.1 
Adverse Events 
Adverse events will be coded to a Medical Dictionary for Regulatory Activities 
(MedDRA) preferred term and system organ classification.  The occurrence of treatment-
emergent AEs will be summarized using MedDRA preferred terms, system organ 
classifications, and severity.  TEAEs are defined as adverse events that occurred or 
worsened following the first administration of study medication.  Separate summaries of 
treatment-emergent SAEs and TEAEs considered related to study treatment and AEs 
leading to study treatment discontinuation will be generated.  All AEs will be listed for 
individual patients showing both verbatim and preferred terms. 
Ocular and systemic AEs will be reported separately.  Ocular AEs will be split into study 
eye and fellow eye events.  Events reported in ‘both’ eyes will be counted in the study 
and fellow analysis.  Separate causality analyses will be performed for the study eye 
events (related to drug and related to procedure); for fellow eye and systemic events, 
causality will be assessed based on study drug alone.   
9.3.1.2 
Clinical Laboratory Results 
The clinical laboratory results (continuous parameters) will be presented by summary 
statistics for each laboratory parameter within the specific test panel.  In addition, 
summaries will include the change from baseline values at each scheduled post-baseline 
visit.  Laboratory values will be compared to normal range of the laboratory and values 
that fall outside of the normal ranges will be flagged as: H (High) and L (Low) in the data 
listings. 
9.3.1.3 
Vital Signs 
All vital signs parameters will be summarized using descriptive statistics for each 
treatment group for all timepoints assessed, including change from baseline for all post-
treatment assessments.

BCVA 
BCVA will be summarized using descriptive statistics for each treatment group for all 
time points assessed, including change from baseline for all post-treatment assessments.  
BCVA assessment will be split between the study eye and fellow eye. 
9.3.1.5 
Ophthalmic Imaging 
Ophthalmic imaging will be conducted at the last study visit (exit/early termination), and 
these results will be measures of interest.  Parameters will be summarized using 
descriptive statistics by treatment group.  Ophthalmic Imaging assessments will be split 
between the study eye and fellow eye. 
9.3.1.6 
Intraocular Pressure 
IOP will be summarized using descriptive statistics for each treatment group for all time 
points assessed, including change from baseline for all post-treatment assessments.  
BCVA assessment will be split between the study eye and fellow eye. 
9.3.1.7 
Systemic PK  
The amount of study drug present in the patient plasma will be summarized at each time 
point.  ONL1204 concentrations that are below the quantitation limit (BQL) will be set to 
0 if before the first quantifiable concentration and to 0 thereafter for all descriptive 
analyses of ONL1204.  For the calculation of geometric mean and geometric CV%, all 
BQL values will be set to missing.  The number of BQL values at each time point will be 
summarized through frequency counts and percentages. 
9.3.1.8 
Other Parameters 
Other safety data will be listed by treatment group and may be further evaluated through 
descriptive summaries.  Concomitant medications will be coded using the World Health 
Organization drug dictionary and summarized by treatment group. 
9.3.2 
Ocular PK Analyses 
Ocular PK will be analyzed per treatment group as well as per protocol across all 
treatment groups.  Concentration data from the bioanalysis of the ocular fluid samples 
will be reported in summary tables.  Pharmacokinetic parameters (e.g., Tmax, Cmax, 
terminal t1/2, AUC0-last, and AUC0-infinity) may be calculated based on the 
concentration data from the bioanalysis of the collected samples, if appropriate.

The decision to dose-escalate to the next cohort will include evaluation of potential dose 
limiting toxicities as detailed in Section 4.2.1 as well as adverse events, clinical 
laboratory evaluations and ophthalmologic imaging data.  Applicable sections of the 
Common Terminology Criteria for Adverse Events (CTCAE) version 5, 17Nov2017 will 
be used to grade adverse events. 
10.3 Human Research Ethics Committee 
The study will be conducted in accordance with applicable regulatory requirement(s) and 
will adhere to GCP standards.  The HREC will review all appropriate study 
documentation to safeguard the rights, safety, and well-being of the patients.  The study 
will be conducted only at sites where HREC approval has been obtained.  The protocol, 
IB, informed consent form, advertisements (if applicable), written information given to 
the patients, safety updates, annual progress reports, and any revisions to these 
documents will be provided to the HREC by the investigator or the sponsor, as allowed 
by local regulations. 
10.4 Informed Consent 
After the study has been fully explained, written informed consent will be obtained from 
the patient before study participation.  The method of obtaining and documenting the 
informed consent and the contents of the consent must comply with the ICH GCP and all 
applicable regulatory requirements. 
10.5 Records Management 
The investigator is required to prepare and maintain adequate and accurate case histories 
designed to record all observations and other data pertinent to the study for each study 
patient.  Study data will be entered into an eCRF by site personnel using a secure, 
validated, web-based electronic data capture (EDC) application.  ONL Therapeutics will 
have access to all data upon entry in the EDC application. 
Study monitors will discuss instances of missing or uninterpretable data with the 
investigator for resolution.  Any changes to study data will be made to the eCRF and 
documented via an electronic audit trail associated with the affected eCRF. 
10.6 Source Documentation 
The study sites will be provided with secure access to and training on the EDC 
application, sufficient to permit site personnel to enter or correct information in the 
eCRFs for the patients for whom they are responsible.

Ethical Principles for Medical Research Involving Human Subjects,  
Adopted by the 18th WMA General Assembly Helsinki, Finland, June 1964 and amended 
by the: 
29th WMA General Assembly, Tokyo, Japan, October 1975 
35th WMA General Assembly, Venice, Italy, October 1983 
41st WMA General Assembly, Hong Kong, September 1989 
48th WMA General Assembly, Somerset West, Republic of South Africa, October 1996, 
and the 
52nd WMA General Assembly, Edinburgh, Scotland, October 2000 
A. 
INTRODUCTION 
The World Medical Association has developed the Declaration of Helsinki as a statement 
of ethical principles to provide guidance to physicians and other participants in medical 
research involving human subjects.  Medical research involving human subjects includes 
research on identifiable human material or identifiable data. 
It is the duty of the physician to promote and safeguard the health of the people.  The 
physician’s knowledge and conscience are dedicated to the fulfillment of this duty.

The Declaration of Geneva of the World Medical Association binds the physician with 
the words, "The health of my subject will be my first consideration," and the International 
Code of Medical Ethics declares that, "A physician shall act only in the subject's interest 
when providing medical care which might have the effect of weakening the physical and 
mental condition of the subject." 
Medical progress is based on research, which ultimately must rest in part on 
experimentation involving human subjects. 
In medical research on human subjects, considerations related to the well-being of the 
human subject should take precedence over the interests of science and society. 
The primary purpose of medical research involving human subjects is to improve 
prophylactic, diagnostic and therapeutic procedures and the understanding of the etiology 
and pathogenesis of disease.  Even the best-proven prophylactic, diagnostic, and 
therapeutic methods must continuously be challenged through research for their 
effectiveness, efficiency, accessibility and quality. 
In current medical practice and in medical research, most prophylactic, diagnostic and 
therapeutic procedures involve risks and burdens. 
Medical research is subject to ethical standards that promote respect for all human beings 
and protect their health and rights.  Some research populations are vulnerable and need 
special protection.  The particular needs of the economically and medically 
disadvantaged must be recognized.  Special attention is also required for those who 
cannot give or refuse consent for themselves, for those who may be subject to giving 
consent under duress, for those who will not benefit personally from the research, and for 
those for whom the research is combined with care. 
Research investigators should be aware of the ethical, legal, and regulatory requirements 
for research on human subjects in their own countries as well as applicable international 
requirements.  No national ethical, legal, or regulatory requirement should be allowed to 
reduce or eliminate any of the protections for human subjects set forth in this Declaration. 
B. 
BASIC PRINCIPLES FOR ALL MEDICAL RESEARCH 
It is the duty of the physician in medical research to protect the life, health, privacy, and 
dignity of the human subject. 
Medical research involving human subjects must conform to generally accepted scientific 
principles, be based on a thorough knowledge of the scientific literature, other relevant 
sources of information, and on adequate laboratory and, where appropriate, animal 
experimentation.

ONL1204

Appropriate caution must be exercised in the conduct of research, which may affect the 
environment, and the welfare of animals used for research must be respected. 
The design and performance of each experimental procedure involving human subjects 
should be clearly formulated in an experimental protocol.  This protocol should be 
submitted for consideration, comment, guidance, and where appropriate, approval to a 
specially appointed ethical review committee, which must be independent of the 
investigator, the sponsor or any other kind of undue influence.  This independent 
committee should be in conformity with the laws and regulations of the country in which 
the research experiment is performed.  The committee has the right to monitor ongoing 
trials.  The researcher has the obligation to provide monitoring information to the 
committee, especially any SAEs.  The researcher should also submit to the committee, for 
review, information regarding funding, sponsors, institutional affiliations, other potential 
conflicts of interest and incentives for subjects. 
The research protocol should always contain a statement of the ethical considerations 
involved and should indicate that there is compliance with the principles enunciated in 
this Declaration.  
Medical research involving human subjects should be conducted only by scientifically 
qualified persons and under the supervision of a clinically competent medical person.  
The responsibility for the human subject must always rest with a subject of the research, 
even though the subject has given consent. 
Every medical research project involving human subjects should be preceded by careful 
assessment of predictable risks and burdens in comparison with foreseeable benefits to 
the subject or to others.  This does not preclude the participation of healthy volunteers in 
medical research.  The design of all studies should be publicly available. 
Physicians should abstain from engaging in research projects involving human subjects 
unless they are confident that the risks involved have been adequately assessed and can 
be satisfactorily managed.  Physicians should cease any investigation if the risks are 
found to outweigh the potential benefits or if there is conclusive proof of positive and 
beneficial results. 
Medical research involving human subjects should only be conducted if the importance 
of the objective outweighs the inherent risks and burdens to the subject.  This is 
especially important when the human subjects are healthy volunteers. 
Medical research is only justified if there is a reasonable likelihood that the populations 
in which the research is carried out stand to benefit from the results of the research. 
The subjects must be volunteers and informed participants in the research project.

The right of research subjects to safeguard their integrity must always be respected.  
Every precaution should be taken to respect the privacy of the subject, the confidentiality 
of the subject’s information and to minimize the impact of the study on the subject's 
physical and mental integrity and on the personality of the subject. 
In any research on human beings, each potential subject must be adequately informed of 
the aims, methods, sources of funding, any possible conflicts of interest, institutional 
affiliations of the researcher, the anticipated benefits and potential risks of the study, and 
the discomfort it may entail.  The subject should be informed of the right to abstain from 
participation in the study or to withdraw consent to participate at any time without 
reprisal.  After ensuring that the subject has understood the information, the physician 
should then obtain the subject's freely-given informed consent, preferably in writing.  If 
the consent cannot be obtained in writing, the non-written consent must be formally 
documented and witnessed. 
When obtaining informed consent for the research project, the physician should be 
particularly cautious if the subject is in a dependent relationship with the physician or 
may consent under duress.  In that case the informed consent should be obtained by a 
well-informed physician who is not engaged in the investigation and who is completely 
independent of this relationship. 
For a research subject who is legally incompetent, physically or mentally incapable of 
giving consent or is a legally incompetent minor, the investigator must obtain informed 
consent from the legally authorized representative in accordance with applicable law.  
These groups should not be included in research unless the research is necessary to 
promote the health of the population represented and this research cannot instead be 
performed on legally competent persons. 
When a subject deemed legally incompetent, such as a minor child, is able to give assent 
to decisions about participation in research, the investigator must obtain that assent in 
addition to the consent of the legally authorized representative. 
Research on individuals from whom it is not possible to obtain consent, including proxy 
or advance consent, should be done only if the physical/mental condition that prevents 
obtaining informed consent is a necessary characteristic of the research population.  The 
specific reasons for involving research subjects with a condition that renders them unable 
to give informed consent should be stated in the experimental protocol for consideration 
and approval of the review committee.  The protocol should state that consent to remain 
in the research should be obtained as soon as possible from the individual or a legally 
authorized surrogate. 
Both authors and publishers have ethical obligations.  In publication of the results of 
research, the investigators are obliged to preserve the accuracy of the results.  Negative as 
well as positive results should be published or otherwise publicly available.  Sources of

C. 
ADDITIONAL PRINCIPLES FOR MEDICAL RESEARCH COMBINED 
WITH MEDICAL CARE 
The physician may combine medical research with medical care, only to the extent that 
the research is justified by its potential prophylactic, diagnostic, or therapeutic value.  
When medical research is combined with medical care, additional standards apply to 
protect the subjects who are research subjects. 
The benefits, risks, burdens, and effectiveness of a new method should be tested against 
those of the best current prophylactic, diagnostic, and therapeutic methods.  This does not 
exclude the use of placebo, or no treatment, in studies where no proven prophylactic, 
diagnostic or therapeutic method exists. 
At the conclusion of the study, every subject entered into the study should be assured of 
access to the best-proven prophylactic, diagnostic, and therapeutic methods identified by 
the study. 
The physician should fully inform the subject which aspects of the care are related to the 
research.  The refusal of a subject to participate in a study must never interfere with the 
subject-physician relationship. 
In the treatment of a subject, where proven prophylactic, diagnostic, and therapeutic 
methods do not exist or have been ineffective, the physician, with informed consent from 
the subject, must be free to use unproven or new prophylactic, diagnostic, and therapeutic 
measures, if in the physician’s judgment it offers hope of saving life, re-establishing 
health, or alleviating suffering.  Where possible, these measures should be made the 
object of research, designed to evaluate their safety and efficacy.  In all cases, new 
information should be recorded and, where appropriate, published.  The other relevant 
guidelines of this Declaration should be followed.
