DEVICE 
Crosslinked Thiolated Carboxymethyl Hyaluronic Acid 0.75% (CMHA-S) 
STUDY OBJECTIVE 
The objective of this study is to evaluate the safety and effectiveness of topical 
Ocular Bandage Gel (OBG) in patients with persistent corneal epithelial defects 
(PED).  Ocular Bandage Gel (OBG) will be administered six (6) times per day while 
awake for 4 weeks. 
The primary exploratory effectiveness outcome for this study is the percentage of 
patients achieving corneal healing (<0.5 mm lesion size) as determined by corneal 
fluorescein staining and photos.  The effectiveness endpoint will be evaluated by a 
reader using digital photography of fluorescein stained slit lamp photos.    
STUDY DESIGN 
 
This is a prospective, exploratory study in which up to 10 patients (up to 20 eyes 
[minimum of 10 eyes]) diagnosed with Stage 1 and Stage 2 PED (as defined by 
fluorescein staining of the cornea and refractory to one or more conventional non-
surgical treatments of at least 2 weeks) will receive OBG with a dosing regimen of 
six (6) times per day over 4 weeks (Sacchetti 2014). 
Both eyes are to be included if both eyes meet inclusion criteria and both eyes will 
be treated with OBG.  When only one eye meets all eligibility criteria only that eye 
can be enrolled into the study.  The fellow eye can be treated per the investigator’s 
discretion, but the site will provide the subject with careful instruction so that study 
treatment is applied appropriately and only to the study eye.  Study assessments do 
not need to be done on the fellow eye at future study visits after non-eligibility is 
determined. 
 
Patients will self-administer all treatments.  All subjects will be followed through 
the 4-week study with follow-up visits at Week 1 (± 1 day), Week 2 (± 2 days), 
Week 3 (± 2 days), and Week 4 (± 2 days).  
CLINICAL SITE

NUMBER OF SUBJECTS 
Up to 20 eyes (minimum 10 eyes) of 10 patients diagnosed with PED as defined by 
fluorescein staining of the cornea and refractory to one or more conventional non-
surgical treatments of at least 2 weeks. Only one eye is required to qualify in order 
to be randomized into the study. In the event that a patient is enrolled with both eyes 
affected, both eyes will be entered as study eyes and followed for safety and 
effectiveness.

contact lens warpage, and/or herpes keratitis. 
• Stage 3 PED or evidence of corneal ulceration, corneal melting or perforation in 
the affected eye(s). Stage 3 PED is defined as those characterized by corneal 
ulcer with stromal involvement that may be complicated by stromal melting and 
progression to corneal perforation (Sacchetti 2014). 
• Use of medications that may affect and/or decrease the rate of corneal healing 
[e.g., systemic and or topical medications (corticosteroids more than 2 drops per 
day and antimetabolites such as mitomycin) and/or antiviral medications] and or 
recent use (within the past 6 months) of isotretinoin, amiodarone, or any 
medications that can affect corneal integrity. 
• Presence or history of any ocular or systemic disorder or condition that might 
hinder the effectiveness of the study treatment or its evaluation, could possibly 
interfere with the interpretation of study results, or be judged by the investigator 
to be incompatible with the study visit schedule or conduct (e.g., progressive or 
degenerative corneal or retinal conditions, uveitis, optic neuritis, poorly 
controlled diabetes, autoimmune disease, systemic infection, neoplastic 
diseases). Diabetes is not an exclusion for study entry as long as the patient is 
under stable control and no medication changes are required during the duration 
of the study.  
• Have moderate and/or severe blepharitis and/or meibomitis requiring a change 
in treatment in either eye in the past 30 days prior to screening (mild or moderate 
blepharitis and/or meibomitis is permitted if on stable therapy, such as lid 
hygiene and/or oral Omega 3 fatty acids [FAs], for at least 30 days prior to 
screening and is not expected to change for the duration of the trial). 
• Ocular surgery not allowed during the study treatment period.  
• Known hypersensitivity to one of the components of the study or procedural 
medications (e.g., fluorescein).

1. INTRODUCTION AND BACKGROUND  
DESCRIPTION OF PERSISTENT CORNEAL EPITHELIAL DEFECTS (PED) 
 
Persistent corneal epithelial defects (PED) can be defined as a loss of the integrity of the corneal surface and 
or a defect in the epithelium, caused by injury or disease, which does not heal by itself within the usual time 
frame (usually defined as within 14 days) but persists for weeks or even months (Jeng 2011a).  Several 
underlying disease states may result in PED.  Nonhealing corneal epithelial defects may also occur after 
ocular surgery or other physical injuries and/or trauma to the cornea.  These defects can be especially 
troublesome and difficult to heal in diabetics.  These nonhealing defects can lead to corneal ulcers, corneal 
scarring, and opacification and result in visual loss (Lu 2001).  
 
Corneal epithelial wound healing or re-epithelization is a highly regulated process that involves the 
reorganization, migration, and proliferation of epithelial cells from the limbal stem cells (Dua 2000, Rama 
2010).  Rapid re-epithelialization of the injured area is extremely important in reducing the risk of microbial 
superinfection and corneal opacification.  Delays in this process may result in corneal scarring, ulceration, 
and opacification.  Compounds that can accelerate wound closure and activate this highly regulated process 
are of interest because of their major potential benefit for patients with persistent epithelial damage from dry 
eye, surgical and non-surgical trauma, refractive interventions, corneal abrasion, nonhealing corneal ulcers 
and neurotrophic corneas secondary to diabetes, cranial nerve palsies, and herpetic keratitis (Lu 2001).  
 
There is an unmet medical need for a therapy that could help heal the cornea.  The current standard of care 
to help re-epithelialize a cornea are “bandage” methods and include aggressive lubricants, debridement and 
patching, applying a bandage contact lens, human amniotic membrane, use of autologous serum as a 
supernatant to provide necessary growth factors, suturing the lids via a tarsorrhaphy, or in severe cases 
applying a conjunctival graft over the cornea (Blackmore 2010, Meller 2011, Young 2004, Jeng 2011b, 
Pakarinen 1987, Thoft 1977).  These are attempts to cover the corneal epithelial defect and allow the cells to 
migrate in and heal.  With autologous serum, the attempt is to capture and apply naturally occurring growth 
factor and “healing proteins” from one’s own bodily fluids.  However, none are effective universally.  Often 
these PED cases recur and end up being costly to the patients and the healthcare provider. 
 
Agents that can accelerate wound closure by increasing the migration and proliferation of corneal epithelial 
cells are of interest because of their potential benefit for patients with persistent epithelial damage.  Patients 
with PED could benefit significantly from such a topical preparation that could allow the healthy limbal cells 
to migrate and heal. 
 
1.2 UNDERLYING DISEASES WITH PERSISTENT CORNEAL EPITHELIAL DEFECTS*  
 
Persistent corneal epithelial defects (PED) is a condition that has a duration of less than one year.  Underlying 
disease states that may result in such defects include exposure keratopathy, limbal stem cell deficiency, 
previous herpes simplex or herpes zoster infection, diabetic keratopathy, neurotrophic keratopathy following 
corneal transplant surgery, diabetic vitrectomy, and severe dry eye states (McCulley 1993, Jeng 2011a). 
 
Exposure Keratopathy 
Exposure keratopathy is the result of incomplete lid closure (lagophthalmos) that causes drying of the cornea 
despite normal tear production.  Among the causes of exposure keratopathy are cranial nerve palsy, 
aneurysm, herpes infection, and lid malposition.  No prevalence data on exposure keratopathy in the U.S. 
were identified.

Limbal Stem Cell Deficiency 
Limbal stem cell deficiency is a disease in which the stem cell functions of the limbus and the barrier function 
of the limbus fail.  Because of failure of corneal epithelial healing from limbal stem cells, as a result of either 
loss or dysfunction, corneal epithelial defects appear and fail to heal normally (Ahmad 2012).   
 
Herpes Simplex 
The incidence of ocular herpes simplex in the U.S. is 20.7 per 100,000 person-years and the prevalence is 
149 per 100,000 persons (Liesegang 2001, Young 2004).  Corneal complications in patient with herpes 
simplex are of two main types: epithelial keratitis is inflammation of the cells that form the surface layer of 
the cornea, and stromal keratitis is inflammation of the middle layer (stroma) of the cornea.  The effects of 
herpes simplex stromal keratitis include scarring, tissue destruction, neovascularization, glaucoma, and 
persistent epithelial defects.  Of the ocular herpes simplex cases in the U.S., 72% of cases had corneal-
epithelial involvement (Liesegang 1989). 
 
Herpes Zoster 
Herpes zoster ophthalmicus, or ocular shingles, is a rash that involves the nerve that innervates the skin 
around the upper eyelid, forehead, and scalp (Hall 2003).  Neurotrophic keratitis can be the end result of 
decreased corneal sensation from herpes zoster virus-mediated destruction, including susceptibility to 
mechanical trauma, decreased lacrimation, and delayed epithelial healing.  The incidence of herpes zoster 
ophthalmicus in the U.S. is 40,000 to 60,000 cases per year.  Twenty-five (25%) to 50% of these cases have 
ocular involvement, 16% of which develop neurotrophic keratopathy (Shaikh 2002).   
 
Diabetic Keratopathy 
Diabetic keratopathy has been estimated to occur in 47-64% of diabetic patients during the course of their 
disease, and diabetics have an increased risk of developing epithelial fragility corneal epithelial defects, 
recurrent epithelial erosions, decreased sensitivity, abnormal wound healing, increased susceptibility to 
injury, and non-healing or infected corneal ulceration (Schultz 1981, Abdelkader 2011).  Recurrent corneal 
erosions in patients with diabetes are usually post traumatic and the result of apparently mild epithelial 
breakdown following cataract or vitreoretinal surgery (Jeganathan 2008).  Neuropathic keratopathy is an 
uncommon complication of diabetes but it can cause corneal ulceration (Lockwood 2006).   
 
Neurotrophic Keratopathy 
Neurotrophic keratopathy is a degenerative disease of the corneal epithelium resulting from impaired corneal 
innervation.  A reduction in corneal sensitivity or complete corneal anesthesia is the hallmark of this disease 
and is responsible for producing epithelial keratopathy, ulceration, and perforation (Bonini 2003).  It is most 
commonly due to herpes infection, chemical injury, or trauma.  No data were identified concerning the 
prevalence of PED in patients with neurotrophic keratopathy.  The potential prevalence of PED in patients 
with neurotrophic keratopathy is included in the prevalence numbers estimated for patients with herpes 
infection and corneal burns. 
 
Corneal Transplantation 
The number of corneal transplants (also referred to as keratoplasty, penetrating keratoplasty, or corneal graft) 
in 2011 was equal to 46,081 (Eye Bank Association of America®).  The incidence of corneal PED following 
corneal transplants is 16.4% (Rumelt 2008).   
 
Diabetic Vitrectomy 
In the U.S. 250,000 vitrectomy surgeries are performed annually with an estimated 25% to 53% performed 
for diabetics (Virata 1999).  The frequency of epithelial debridement during diabetic vitrectomy is 17.4%

(Friberg 2003).  Corneal epithelial defects were found in 22.8% of eyes at 2 weeks after corneal epithelial 
debridement during diabetic vitrectomy (Chen 2009).   
 
Severe Dry Eye States 
Persistent corneal epithelial defects (PED) can occur in mucin-deficient dry eye states in patients with 
Stevens-Johnson syndrome or ocular cicatricial pemphigoid or in patients with lacrimal gland dysfunction 
such as Sjögren’s disease.  The prevalence of dry eye disease in the U.S. among men older than 50 is 3.9-
7.6% and among women is 5.7% in women less than 50 years of age to 9.8% among women 75 years of age 
or older (Schaumberg 2009, Schaumberg 2003).   
 
Corneal Burns 
The incidence of ocular trauma is 3.1 cases per 1,000 person-years (Wong 2000).  Chemical or thermal burns 
are involved in 7.7% to 18% of all ocular traumas (Kuckelkorn 2002).  Approximately 20% of all ocular 
burns result in PEDs.

THE OCULAR BANDAGE GEL 
The Ocular Bandage Gel is a stand-alone device that acts as a barrier that minimizes mechanical lid friction 
and mechanically protects the ocular surface thereby reducing repeat injury and providing an environment 
that enables the body to repair the ocular surface whether the corneal epithelial defects are large or small.  
Unlike a semi-rigid film, the Ocular Bandage Gel has an optimized viscosity as a sterile liquid gel which 
allows it to be administered to the eye from a dropper bottle and is intended for up to six (6) daily applications. 
The Ocular Bandage Gel is designed to be optically clear with application on the eye and the product is 
provided sterile in a preservative free multi-dose dropper bottle for commercialization.   
 
2.1 COMPOSITION AND PROPERTIES OF THE OCULAR BANDAGE GEL 
 
OBG is being evaluated in an ongoing pivotal study for the acceleration of re-epithelization of corneal 
epithelial defects following photorefractive keratectomy (PRK). It is also the subject of a pilot study for dry 
eye patients with punctate epitheliopathies (PE). The OBG consists of a cross-linked thiolated carboxymethyl 
hyaluronic acid (CMHA-S) that is designed to resist degradation, thus prolonging the dwell time on the ocular 
surface of upwards of 2 hours (EyeGate data). The viscosity of the OBG has been shown to aid in ocular 
wound repair by acting as a mechanical moisture barrier and offering physical protection (Chen 1999, 
Wirostko 2014, Yang 2010).  
 
The OBG is presently available commercially as a veterinary device, manufactured by SentrX Animal Care 
(Salt Lake City, UT) and sold in the U.S. by Bayer Animal Health as Remend® Corneal Repair (0.75% 
concentration), indicated for use in the management of superficial corneal ulcers and Remend® Eye 
Lubricating Drops (0.40% concentration) for the treatment of dry eye in dogs and cats (Williams 2013, 
Williams 2014, Williams 2017). The product has been used for more than seven years in dogs, cats and 
horses, with an excellent safety profile and has been shown to manage non-healing corneal wounds and 
improve dry eye (Williams 2017). The composition of the corneal repair veterinary product is identical to 
that of the OBG.

3. COMPLETED Clinical Performance studies 
The well-controlled studies conducted by EyeGate (EYEGATE-031, EYEGATE-033, EYEGATE-034 for 
PRK, and OBG PE-041 and OBG PE-042 in PE) demonstrate Ocular Bandage Gel safety and effectiveness 
to protect the ocular surface and facilitate healing of corneal epithelial defects associated with ocular surface 
disorders following surgery and related to non-traumatic indications like PEs. In these clinical trials EyeGate 
evaluated two patient populations, both with recognized ocular surface pathology that could be objectively 
assessed for meaningful improvements, i.e., closure of large epithelial defects post-PRK surgery and 
improvement in corneal staining in dry eye subjects with PE.  
 
In five (5) clinical studies, conducted in the U.S., EyeGate has collected data on 368 eyes from 194 subjects 
that have been exposed to OBG as a stand-alone device.  See Table 1 below.  These 368 eyes (194 subjects) 
include 234 eyes (117 subjects) in the EYEGATE-034 pivotal study, 60 eyes (30 subjects) in the EYEGATE-
033 study, 24 eyes (12 subjects) in the EYEGATE-031 study, 30 eyes (15 subjects) in the OBG PE-041 
study, and 20 eyes (20 subjects) in the OBG PE-042 study. The OBG arms have demonstrated no safety 
concerns with excellent tolerability where OBG has been administered a minimum of 4 times/day with 
applications up to 28 days. 
 
3.1 SUMMARY  
 
The clinical data generated to date serve to help support the safety and effectiveness of the Ocular Bandage 
Gel for use in managing and improving the signs and symptoms of various epithelial defects.  Initial safety 
and effectiveness findings following use of the Ocular Bandage Gel in subjects who had undergone PRK 
were very encouraging, with no significant safety concerns and evidence of earlier corneal re-epithelialization 
than artificial tears and a bandage contact lens.

4. OBG PED-001 
4.1 
STUDY OBJECTIVE  
The objective of this study is to evaluate the safety and effectiveness of topical Ocular Bandage Gel (OBG) 
in patients with persistent corneal epithelial defects (PED).  Ocular Bandage Gel (OBG) will be administered 
six (6) times per day while awake for 4 weeks. 
 
The primary exploratory effectiveness outcome for this study is the percentage of patients achieving corneal 
healing (<0.5 mm lesion size) as determined by corneal fluorescein staining and photos. The effectiveness 
endpoint will be evaluated by a reader (using digital photography of fluorescein stained slit lamp photos.    
 
4.2 STUDY DESIGN  
 
Both eyes are to be included if both eyes meet inclusion criteria and both eyes will be treated with OBG.  
When only one eye meets all eligibility criteria only that eye can be enrolled into the study.  The fellow eye 
can be treated per the investigator’s discretion, but the site will provide the subject with careful instruction 
so that study treatment is applied appropriately and only to the study eye.  Study assessments do not need to 
be done on the fellow eye at future study visits after non-eligibility is determined. 
 
Patients will self-administer all treatments.  Study subjects will be instructed to administer the investigational 
Ocular Bandage Gel 6 times per day for the 4 week treatment period.  All subjects will be followed through 
the 4-week study with follow-up visits at Week 1 (± 1 day), Week 2 (± 2 days), Week 3 (± 2 days), and Week 
4 (± 2 days).  All subjects will be instructed to return the investigational study product to the site at the Week 
4 visit (Day 28 ±2 days). 
If a subject being treated with OBG deteriorates such that there is an increase in the PED lesion size ≥ 1 mm 
and/or progression in lesion depth to corneal melting or perforation and/or onset of infection, the investigator 
is to discontinue the study treatment as appropriate and rescued at the discretion of the investigator.  Rescued 
subjects will be followed to Week 4 and not discontinued from study assessments. 
4.3 STUDY OUTCOMES 
The exploratory effectiveness endpoints in this study are as follows: 
• 
Percentage of patients achieving corneal healing (<0.5 mm lesion size) of the PED determined by 
corneal fluorescein staining at Week 4.  The effectiveness endpoint will also be evaluated by a reader 
using digital photography of fluorescein stained slit lamp.    
• 
Time to complete corneal healing (<0.5 lesion size)  
• 
Investigator global evaluation of effectiveness at Week 4 
The following safety assessments will be collected in both eyes of each subject and the outcomes 
summarized: 
• 
Slit Lamp biomicroscopy 
• 
UCVA 
• 
AEs 
This is a prospective, exploratory study in which up to 10 patients (up to 20 eyes [minimum of 10 eyes]) 
diagnosed with Stage 1 and Stage 2 PED (as defined by fluorescein staining of the cornea and refractory to 
one or more conventional non-surgical treatments of at least 2 weeks) will receive OBG with a dosing 
regimen of six (6) times per day over 4 weeks (Sacchetti 2014).

5.  STUDY PROCEDURES 
5.1 INFORMED CONSENT 
The study will be discussed and the informed consent document (ICD) will be reviewed with each prospective 
subject by the investigator or a trained clinical professional.  Once the subject has been informed of all aspects 
of the study, the subject will be given a choice to voluntarily confirm participation in the study as documented 
by completion of the Informed Consent.  After signing the ICD and any other applicable local documentation, 
the site can then proceed with the screening evaluation.   
The subject’s signed and dated informed consent must be obtained before conducting any procedure 
specifically for the study.  Subjects are deemed Screen Failures if upon signing the ICD they subsequently 
fail to meet the eligibility criteria.

The investigator must retain the original, signed written ICD.  A copy of the written ICD must be given to 
the subject. 
 
5.2 SCREENING EVALUATION  
After signing the ICD, all potential subjects will undergo an initial screening on Day 0 (Baseline) to determine 
study eligibility.  Ten (10) subjects who meet all of the inclusion criteria and none of the exclusion criteria 
will be enrolled into the study.  
 
This is a prospective, exploratory study in which up to 10 patients (up to 20 eyes [minimum of 10 eyes]) 
diagnosed with Stage 1 and Stage 2 PED (as defined by fluorescein staining of the cornea and refractory to 
one or more conventional non-surgical treatments of at least 2 weeks) will receive OBG with a dosing 
regimen of six (6) times per day over 4 weeks (Sacchetti 2014).. 
 
Both eyes are to be included if both eyes meet inclusion criteria and both eyes will be treated with OBG.  
When only one eye meets all eligibility criteria only that eye can be enrolled into the study.  The fellow eye 
can be treated per the investigator’s discretion, but the site will provide the subject with careful instruction 
so that study treatment is applied appropriately and only to the study eye.  Study assessments do not need to 
be done on the fellow eye at future study visits after non-eligibility is determined. 
 
5.3 SUBJECT ID NUMBER 
A 3-digit subject identification (SubjID) number will be assigned at the clinical site during Screening and be 
used to identify the subject throughout their participation. The first digit of the SubjID number will be the 
site number which will be “1” for this study.  The last 2 digits of the SubjID number will be a sequential 
number, using a leading “0”, according to an individual site’s enrollment.  For example, the seventh subject 
screened will have a SubjID number of “1-07”. 
 
The SubjID number and patient initials are to be recorded on all study documents and will link the study 
documents to the patient’s name and medical record. To maintain confidentiality, the patient’s name should 
not be recorded on any study document other than the ICD.  This is an open-label study and there is no 
randomization or other identifying number.   
 
5.4 SCREEN FAILURE 
The study site will document all screen failures on the Subject Screening/Enrollment Log with the coded 
reason (by Inclusion or Exclusion number) for not enrolling the subject. Collected screen failure baseline 
visit data for demographics and non-eligibility will be entered onto study CRFs and screen failure ICDs and 
source documents will be made accessible by the site during site monitoring visits.  
 
5.5 INVESTIGATIONAL TREATMENT ADMINISTRATION  
Subjects will be screened at Baseline (Day 0) to determine eligibility.  Eligible study subjects will be 
instructed to administer the investigational Ocular Bandage Gel 6 times per day for the 4 week treatment 
period.   
 
• 
Treatment:  Ocular Bandage Gel 6 times per day for 28 days (4 weeks).  Treatment will be in both 
eyes only if both eyes meet all study eligibility criteria

At Baseline (Day 0) the investigator will dispense Ocular Bandage Gel to the subject.  If only one eye is 
eligible for the study the investigator or study coordinator will review which eye to administer the study 
treatment.  The subject will be given one (1) sterile, preservative free multi-dose dropper bottle of Ocular 
Bandage Gel.  Subjects will be given a Patient Instructions document to refer to for Ocular Bandage Gel self-
administration.  The site will observe the patient apply Ocular Bandage Gel in their eye(s) at the Baseline 
visit.  After the Baseline visit subjects will administer the study treatment at home and document all 
applications and application times using a study Patient Diary provided by the site.  At each visit the study 
coordinator will review the study Patient Diary.  Subjects will need to bring all the study eye drops with them 
at all visits.  If for any reason a patient loses or damages their bottle of OBG during the study, they should 
contact the site to obtain a replacement as soon as possible so that no or minimal doses are missed.  Missed 
or late applications will be documented in the Patient Diary.  Subjects will return used and unused bottles of 
Ocular Bandage Gel to the study coordinator at the Day 28 visit.   
 
On study visit days there should be at least two (2) hours between the last OBG instillation and the visit.   
 
5.6 RESCUE 
If a subject being treated with OBG deteriorates such that there is an increase in the PED lesion size ≥ 1 mm 
and/or progression in lesion depth to corneal melting or perforation and/or onset of infection, the investigator 
is to discontinue the study treatment as appropriate and rescue the patient as appropriate per the discretion of 
the investigator.  Rescued subjects will be followed to Week 4 for safety purposes and not discontinued from 
study assessments. 
 
5.7 SCHEDULE OF VISITS 
There are a total of five (5) study visits starting with the Baseline (Day 0) visit.  Participating subjects will 
return to the clinic for examination on Week 1 (Day 7 ± 1 day), Week 2 (Day 14, ± 2 days), Week 3(Day 21, 
± 2 days), and Week 4 (Day 28, ± 2 days).  Study exit is done at the Week 4 visit.  Clinic visits should occur 
around the same time of day (i.e. all visits in the morning or all visits in the afternoon).  On study visit days 
there should be at least two (2) hours between the last OBG instillation and the visit.

5.10 SUBJECT WITHDRAWAL 
All subjects have the right to withdraw at any point during the treatment without prejudice.  The investigator can 
discontinue any subject at any time if continued participation in the study would result in harm to the subject.  All 
efforts should be made by the investigator to retain the patient in the study.  If a subject withdraws prematurely from 
the study, a genuine effort must be made to determine the reason(s) the subject discontinued themselves from the 
study.  The reason must be recorded in the subject’s file and on the End of Study Form and emailed to Kiora 
Pharmaceuticals, Inc. 
 
5.11 LOST TO FOLLOW-UP SUBJECTS 
Subjects who do not return for follow-up must be contacted to ask that they return for the visit.  For those subjects 
who cannot be reached, at least three (3) telephone or email attempts should be made and documented.  If there is 
still no response, the subject will be considered lost-to-follow-up unless there is a further communication by the 
subject. 
 
5.12 PROTOCOL MODIFICATIONS AND DEVIATIONS 
Protocol modifications may be introduced during the study. Prior to implementation of any protocol modifications, a 
protocol amendment will be submitted and cleared by the local Ethics Committee. 
 
Any deviations from this protocol intended to protect the life or physical well-being of a subject in an emergency are 
to be reported to Kiora Pharmaceuticals, Inc. as well as the local Ethics Committee as soon as possible, and no later 
than 5 working days after the emergency occurred. 
 
All protocol deviations will be documented on a Protocol Deviation CRF. 
 
6. DATA HANDLING AND RECORDKEEPING 
6.1 SUBJECT ACCOUNTABILITY 
All subjects randomized in this clinical investigation shall be monitored for the duration of the investigation. The 
clinical investigation shall be considered completed when all subjects who have been enrolled in the investigation, 
including subjects whose study treatment was discontinued early, have reached the final study visit.   
 
6.2 CONFIDENTIALITY 
All medical records associated with the clinical investigation will be made available for review by Kiora 
Pharmaceuticals personnel, its qualified designee and governmental/regulatory agencies involved.  The results of the 
study may be published in the future for scientific and marketing purposes, but the identity (name) of each subject 
will not be revealed.  All records will be stored in a secure area by the investigator, the designee, and at Kiora 
Pharmaceuticals, Inc. 
 
6.3 SOURCE DATA AND CASE REPORT FORMS 
Source documents and paper CRFs (3 part carbonless paper) will be utilized to collect data during this clinical 
investigation.  Source document forms and CRFs are to be maintained and stored by the investigator.  All CRF entries 
must be made in black or blue ink and changes must be made by strike-through only with date and initials or signature.  
No “white-out” is to be used on the source documents or CRFs.  At the end of the trial the original CRFs will remain 
onsite and the monitor or sponsor will retrieve the bottom 2 pages. 
 
6.4 INVESTIGATIONAL PRODUCT ACCOUNTABILITY 
Each shipment of investigational product will include a packing list that will give the amount shipped and the lot 
numbers. This packing list must be reconciled by the investigational site with the contents of the shipment and then 
complete the accountability logs for the Kiora Ocular Bandage Gel. All investigational products at the site must be

                      Kiroa Pharmaceuticals, Inc. (formerly Eyegate) 
 
stored in a secured/locked area at room temperature.  Product reconciliation activities will also be conducted 
periodically in conjunction with site monitoring visits. 
 
The investigator must maintain accurate records of the receipt of all study products shipped to the site, including the 
date and lot numbers received with the use of the appropriate accountability log. The receipt, dispensation, and return 
of the treatment product and control products will be recorded on the logs.  Investigational product can only be 
dispensed to eligible study subjects.   
 
Subjects should return all unused and used Ocular Bandage Gel to the clinic site on Week 4. 
 
6.5 RECORD RETENTION 
Clinical sites are to retain any and all clinical trial material (documentation, photographs, etc.) for a period of two 
years from the date the marketing application is approved or two years after the investigation has been discontinued 
and the local Ethics Committee notified, or as directed by their institutional document retention requirements, 
whichever is the longest.  After that time, the items may be returned to Kiora Pharmaceuticals for archiving.  Unused 
medical products are to be destroyed on site at the conclusion of the enrollment period.  Destruction will be 
documented. 
 
7. EVALUATION OF SAFETY 
Safety will be assessed by determining the incidence and severity of AEs, as well as BCVA findings, and slit lamp 
findings.  
  
Safety outcomes include: 
 
• 
UCVA findings 
• 
Slit lamp findings 
• 
AEs 
• 
VAS  
 
Ocular assessments are bilateral at the Baseline visit (Day 0) when both eyes have a PED and are done in eyes that 
meet study eligibility (unilateral or bilateral at subsequent visits depending on study eligibility determination at 
Baseline). 
 
Throughout the course of the proposed study, all efforts will be made to document possible AEs or untoward findings.  
If an AE occurs, the first concern will be the safety of the subject.  Appropriate medical intervention will be made.  
Any AEs observed by the investigator or reported by the subjects, regardless of severity and whether or not it is 
ascribed to the investigational device, will be recorded.   
 
7.1 ADVERSE EVENT DEFINITIONS 
An AE is any untoward and unintended sign, symptom or disease temporally associated with the use of an 
investigational device or other protocol-imposed intervention, regardless of the suspected cause. Conditions or 
diseases that are chronic but stable should not be recorded on AE pages of the CRF.  Changes in a chronic condition 
of disease that are consistent with natural disease progression are NOT AEs and also should not be recorded on the 
AE pages of the CRF.  Collection of AEs begins at the time of consent.  
 
7.1.1 
Serious Adverse Events (SAE) 
An AE should be classified as an SAE and reported as such, if it meets one or more of the following criteria: 
 
• 
It results in death (i.e., the AE actually causes or leads to death) 
• 
It is life threatening (i.e., the AE places the subject at immediate risk of death) 

PROTOCOL:  OBG PED-001 VERSION 02

• 
It requires or prolongs inpatient hospitalization 
• 
It results in persistent or significant disability/incapacity (i.e., the AE results in substantial disruption of the 
subject’s ability to conduct normal life functions) 
• 
It results in a congenital anomaly/birth defect in a neonate/infant born to a mother exposed to the 
investigational product 
• 
It is considered a significant medical event by the investigator based on medical judgment (e.g., may 
jeopardize the subject or may require medical/surgical intervention to prevent one of the outcomes listed 
above) 
• 
It is considered sight-threatening by the investigator. 
 
If a subject is hospitalized to undergo a medical or surgical procedure as a result of an AE, the event responsible for 
the procedure, not the procedure itself, should be recorded as the event. For example, if a subject is hospitalized to 
undergo coronary bypass surgery, record the heart condition that necessitated the bypass. 
 
Hospitalizations for the following reasons will not be recorded as SAEs: 
• 
Hospitalization or prolonged hospitalization for diagnostic or elective surgical procedures for preexisting 
conditions 
• 
Hospitalization or prolonged hospitalization required to allow outcome measurement for the study 
• 
Hospitalization or prolonged hospitalization for scheduled therapy of the target disease of the study. 
 
7.1.2 
Unanticipated Adverse Device Effects (UADEs) 
An unanticipated adverse device effect (UADE) are defined as any serious adverse effect on health or safety or any 
life-threatening problem or death caused by or associated with a device, if that effect, problem, or death was not 
previously identified in nature, severity or degree of incidence. Anticipated AEs are identified in Section 7.4.  
Unanticipated adverse device effect (UADEs) also include any unanticipated sight-threatening events and any other 
unanticipated serious problem associated with a device that relates to the rights, safety, or welfare of subjects.  
 
Any sight-threatening event, whether listed in the protocol or not, is considered to be reportable as a UADE. Any 
subject presenting with an active AE at the last study visit should be followed until resolution of the AE or until the 
condition is stable with no expected change 
 
7.2 ADVERSE EVENT ASSESSMENT 
All AEs, regardless of severity and whether or not they are ascribed to the study treatment, will be recorded using 
standard medical terminology. The onset date, end date, severity, action(s) taken, relationship to test article and/or 
device, and outcome of all AEs will be documented in the CRFs. The investigator must assess and record in the 
source documents and CRFs whether the event is related to the test article, device and/or procedure. Subjects with an 
AE should be followed to determine outcome. 
 
Documentation regarding the AE should be made as to the nature, onset date, end date, severity, relationship to test 
article, device, action(s) taken, and outcome of any sign or symptom observed by the physician or reported by the 
subject upon indirect questioning.   
 
Whenever possible, recognized medical terms should be used when recording AEs. Colloquialisms and/or abbreviations 
should not be used. Only one medical concept, preferably a diagnosis instead of individual symptoms, should be 
recorded as the event. 
 
If more than one distinct AE occurs, each event should be recorded separately. 
 

PROTOCOL:  OBG PED-001 VERSION 02 
AUGUST 02, 2022

                      Kiroa Pharmaceuticals, Inc. (formerly Eyegate) 
 
However, if known at the time of reporting, a diagnosis (i.e., disease or syndrome) should be recorded on the CRFs 
rather than individual signs and symptoms (e.g., record congestive heart failure rather than dyspnea, rales, and 
cyanosis). However, if a constellation of signs and/or symptoms cannot be medically characterized as a single 
diagnosis or syndrome at the time of reporting, each individual event should be recorded as a separate AE. A diagnosis 
that is subsequently established should be reported as follow-up information. However, signs and symptoms that are 
considered unrelated to an encountered syndrome or disease should be recorded as individual AEs (e.g., if congestive 
heart failure and severe headache are observed at the same time, each event should be recorded as an individual AE). 
 
Adverse events occurring secondary to other events (e.g., sequelae) should be identified by the primary cause; a 
"primary" event, if clearly identifiable, should represent the most accurate clinical term to record as the AE event 
term.  For example: 
Orthostatic hypotension  ⇒fainting and fall to floor ⇒head trauma ⇒neck pain 
The primary event is orthostatic hypotension and the sequelae are head trauma and neck pain. 
 
7.3 CLASSIFICATION OF ADVERSE EVENTS 
7.3.1 
Intensity/Severity 
AE severity is defined as a qualitative assessment of the degree of intensity of an AE as determined by the investigator 
or reported to him/her by the subject. The assessment of severity is made irrespective of test article relationship or 
seriousness of the event and should be evaluated according of the following scale: 
 
Mild:  
Transient discomfort; no medical intervention/therapy required and does not interfere with 
daily activities. 
Moderate:  
Low level of discomfort or concern with mild to moderate limitation in daily activities; some 
assistance may be needed; minimal or no medical intervention/therapy required. 
Marked:  
Considerable discomfort with limitation in daily activities, some assistance usually required; 
medical intervention/therapy usually required. 
Severe:  
Extreme discomfort and limitation in daily activities, significant assistance required; 
significant medical intervention/therapy required. 
 
There is a distinction between the severity and the seriousness of an AE. Severity is a measurement of intensity; thus, 
a severe reaction is not necessarily a SAE.  
 
7.3.2 Relatedness  
The study investigator, in conjunction with the sponsor, will evaluate if the AE is related to the investigational device. 
Relationship is defined in the following manner: 
  
Not related: Evidence indicates no plausible direct relationship to the study device, such that: 
• A clinically plausible temporal sequence is inconsistent with the onset of the AE and device administration; 
and/or 
• A causal relationship is considered biologically implausible 
• The AE can be attributed to concurrent/underlying illness, other drugs, or procedures. 
  
Related: Evidence indicates a reasonable temporal sequence of the event with the study device 
administration exists, or that the association of the event with study device administration is unknown and 
the event is not reasonably supported by other conditions, such that: 
• 
There is a clinically plausible time sequence between onset of the AE and study treatment administration; 
and/or 
• 
There is a biologically plausible mechanism for study treatment causing or contributing to the AE; and 
• 
The AE cannot be reasonably attributed to concurrent/underlying illness, other drugs, or procedures.

                      Kiroa Pharmaceuticals, Inc. (formerly Eyegate) 
 
7.3.3 
Expectedness 
All AEs will be evaluated as to whether they are expected or unexpected. 
  
Expected (anticipated): 
An adverse event is expected when the nature, severity, or degree of 
incidence was previously described.   
Unexpected (unanticipated): An adverse event is unexpected when the nature, severity, or degree of 
incidence was not previously described.  
 
7.3.4 
Outcome 
The clinical outcome of an AE will be characterized as follows: 
• Resolved  
• Unresolved 
• Resolved with sequelae  
• Death 
 
7.3.5 
Treatment or Action Taken 
• 
None 
• 
Treatment Taken 
• 
Hospitalization 
•

7.4 ANTICIPATED ADVERSE EVENTS 
Anticipated AEs include those that might reasonably be expected to occur in this study because they are associated 
with the indication, PE, with the Ocular Bandage Gel, the Refresh PF eye drops or the eye exam procedures. Data 
collection will include a forced recording of anticipated AEs.  A list of anticipated AEs is provided below, as follows: 
 
Ocular Bandage Gel 
• 
Redness of the eye 
• 
Discomfort in the eye 
• 
Allergic reaction 
• 
Temporary blurred vision 
• 
Temporary burning/sting/irritation 
• 
Tearing and/or epiphora 
 
Eye Exams and fluorescein eye drops  
• 
Discomfort in the eye 
• 
Temporary blurred vision due to the drops, lights and photos 
• 
Temporary change in vision 
• 
Eye irritation and or burning and or redness  
• 
Temporary burning and/or stinging from the eye drops used to assess the corneal changes and to be used 
with the photographs and to measure the intraocular pressure 
 
 
7.5 REPORTING SAES AND UNANTICIPATED ADVERSE DEVICE EFFECTS 
 
All SAEs and UADEs will be reported to the sponsor and the medical monitor by e-mail to the addresses below:

edaniels@kiorapharma.com and vlperezmdpa@gmail.com  
 
The report should be made as soon as possible but no later than 24 hours after the investigator first learns of the SAE 
and no later than five (5) working days after the investigator first learns of the UADE.  If required per local Ethics 
Committee guidelines, a report should be sent by the site to the ethics committee in the time required per the 
committee.  An UADE should be documented as an AE using the Adverse Event CRF and then also documented on 
the ADE/UADE form.   All AEs should be documented by completing the AE CRF. 
 
8. MONITORING PLAN 
 
Kiora Pharmaceuticals personnel or qualified designee will monitor the study in a manner consistent with applicable 
health authority regulations and the clinical research standards adopted by Kiora Pharmaceuticals.  Study monitoring 
will involve the following elements: 
 
•

12. APPENDIX 1: EXAMINATION PROCEDURES 
12.1 VISUAL ANALOG SCALE (VAS) 
A VAS will be provided to subjects at visits indicated in Table 2.  The VAS is used in this study to determine the 
pain intensity experienced by individuals. The scale goes from left side or zero “0”, signifying no pain, to the right 
side or “10”, signifying the worst possible pain.  During visit subjects will mark a spot on the line where they feel 
indicates their current level of pain.  A sample VAS is shown in Figure 1.  Sites will measure from 0 to the mark and 
record the value in millimeters as the measurement.

                                            * Not to Scale 
 
 
12.2 SCHIRMER’S TEST 
Bilateral Schirmer’s test will be done bilaterally at visits as indicated in Table 2.  No numbing agents will be used.  
The investigator pulls the bottom eyelid down and a paper test strip is placed inside at 1/3 distance from the temporal 
edge of lid margin. The patient is instructed to close the eye(s) and the paper strip is held in place for 5 minutes.  The 
strip is removed, and test results are evaluated. 
 
Evaluation of the Schirmer's test:  
1. Normal which is ≥15 mm wetting of the paper after 5 minutes. 
2. Mild which is 14-9 mm wetting of the paper after 5 minutes. 
3. Moderate which is 8-4 mm wetting of the paper after 5 minutes. 
4. Severe which is <4 mm wetting of the paper after 5 minutes 
 
12.3 NON-INVASIVE TEAR BREAK UP TIME (NI-BUT) 
A non-invasive way to measure vision fluctuation, analyzing the tear film in its natural state, without disturbing it is 
NI-BUT.  OCULUS Keratograph® is an advanced corneal topographer with a built-in real keratometer and a color

camera that will be used in this study to collect NI-BUT data per the schedule in Table 2. The assessment will be 
performed bilaterally and per the equipment’s manual and will be measured and recorded in seconds on the CRFs. 
12.4 UNCORRECTED VISUAL ACUITY (UCVA) TEST METHODS 
Uncorrected visual acuity (UCVA) at Screening and appropriate scheduled follow-up visits in both eyes per Table 2 
Subjects will remove their glasses or contact lenses.  At a distance of 20 feet (6 meters), from the eye chart, the patient 
will keep both eyes open but cover one eye with the palm of their hand, a piece of paper, or a small paddle.  The 
subject will read aloud the smallest line of letters that they can see on the chart.  The Snellen equivalent will be 
captured on the CRF.   
 
In order to provide standardized and well-controlled assessment of visual acuity, all visual acuity assessments for a 
subject should be performed consistently (e.g., the same lighting conditions, eye chart, viewing distance, etc.) at each 
visit. 
 
12.5 SLIT LAMP EXAMINATION 
Slit lamp biomicroscopy will be performed bilaterally at all study visits, with assessment of the eyelids, puncta, 
conjunctiva, cornea, anterior chamber, lens and anterior vitreous.  Refer to Table 2 for the visit schedule. 
 
12.6 CORNEAL FLUORESCEIN STAINING AND GRADING 
Refer to Table 2 for the visit schedule.   
 
Grading of the corneal fluorescein staining in both eyes will be assessed between 2 to 4 minutes following the 
instillation of 5 μl of 2% sodium fluorescein into the lower conjunctival cul-de-sac of the eye (Figure 2). The 5 μl 
drop of the 2% fluorescein (fluorescein 2 % eye drops, preservative-free solution) will be collected from the container 
using a micropipette.  The National Eye Institute (NEI) scale (Figure 3) will be used to assess corneal staining at the 
slit lamp set at 10X magnification using a broad and diffuse slit lamp beam and a yellow barrier filter to illuminate 
the entire cornea.

FIGURE 2:  CORNEAL FLUORESCEIN STAINING 
 
 
 
 
 
Corneal staining in both eyes will be graded using the NEI staining grid (Figure 3) in which a score of 0 – 3 (0 = 
normal and 3 = severe) will be assigned to each of the five corneal regions (nasal, central, temporal, inferior, and 
superior) with a maximum score of 15.

12.7 SLIT LAMP PHOTOGRAPHY  
Within approximately 30 seconds to 1 minute after the instillation of the fluorescein, the first digital slit lamp corneal 
photo of the study eye will be taken to document the observed corneal findings. Approximately 3 minutes after 
instillation of the fluorescein, the second and third photographs will be taken. The digital corneal slit lamp photos of 
the complete cornea with fluorescein will be taken at 10X magnification using a blue light filter for the main 
illumination and with extra flashlight, if available. All photos taken must show the entire cornea.  
 
All slit lamp photos must be taken per the schedule in Table 2. 
 
The procedures for capturing and exporting slit lamp images of the corneal defect will be detailed in the Imaging 
Procedures Manual that will be provided to each site.  
 
A Cobalt blue light is used to determine the corneal epithelial defects. Three images per eye are captured and exported 
from the slit lamp system.  
 
 
 12.8 PATIENT DIARY 
At the Baseline visit the site will provide the patient with a Patient Diary to document all investigational product 
applications (See Table 2).  A sample of the patient diary is found in Table 3.  At the Week 1, 2, and 3 visits the site 
will review the subject’s entries in the diary and discuss any missed or inappropriately dispensed applications.  
Retraining guidance will be provided.  At the Week 4 visit (Day 28 ±2 days) the Patient Diary will be collected by 
the site.

15. APPENDIX 4: DECLARATION OF HELSINKI 
DECLARATION OF HELSINKI 
 
Adopted by the 18th World Medical Association (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 
52nd WMA General Assembly, Edinburgh, Scotland, October 2000 
53rd WMA General Assembly, Washington DC, United States of America, October 2002    (Note of 
Clarification added) 
55th WMA General Assembly, Tokyo, Japan, October 2004 (Note of Clarification added) 
59th WMA General Assembly, Seoul, Republic of Korea, October 2008  
64th WMA General Assembly, Fortaleza, Brazil, October 2013  
 
A. PREAMBLE 
 
1.  The WMA has developed the Declaration of Helsinki as a statement of ethical principles for 
medical research involving human subjects, including research on identifiable human material and 
data. 
 
2. The Declaration is intended to be read as a whole and each of its constituent paragraphs should be 
applied with consideration of all other relevant paragraphs.   
 
3. Consistent with the mandate of the WMA, the Declaration is addressed primarily to physicians. The 
WMA encourages others who are involved in medical research involving human subjects to adopt 
these principles. 
 
B. GENERAL PRINCIPLES  
 
4. The Declaration of Geneva of the WMA binds the physician with the words, "The health of my 
patient will be my first consideration," and the International Code of Medical Ethics declares that, 
"A physician shall act only in the patient's interest when providing medical care." 
5. It is the duty of the physician to promote and safeguard the health, well-being and rights of patients, 
including those who are involved in medical research. The physician's knowledge and conscience 
are dedicated to the fulfilment of this duty. 
6. Medical progress is based on research that ultimately must include studies involving human 
subjects. 
7. The primary purpose of medical research involving human subjects is to understand the causes, 
development and effects of diseases and improve preventive, diagnostic and therapeutic 
interventions (methods, procedures and treatments). Even the best proven interventions must be 
evaluated continually through research for their safety, effectiveness, efficiency, accessibility and 
quality. 

PROTOCOL:  OBG PED-001 VERSION 02

8. Medical research is subject to ethical standards that promote and ensure respect for all human 
subjects and protect their health and rights. 
9. While the primary purpose of medical research is to generate new knowledge, this goal can never 
take precedence over the rights and interests of individual research subjects. 
10. It is the duty of physicians who are involved in medical research to protect the life, health, dignity, 
integrity, right to self-determination, privacy, and confidentiality of personal information of research 
subjects. The responsibility for the protection of research subjects must always rest with the 
physician or other health care professionals and never with the research subjects, even though they 
have given consent. 
11. Physicians must consider the ethical, legal and regulatory norms and standards for research 
involving human subjects in their own countries as well as applicable international norms and 
standards. No national or international ethical, legal or regulatory requirement should reduce or 
eliminate any of the protections for research subjects set forth in this Declaration. 
12. Medical research should be conducted in a manner that minimizes possible harm to the environment. 
13. Medical research involving human subjects must be conducted only by individuals with the 
appropriate ethics and scientific education, training and qualifications. Research on patients or 
healthy volunteers requires the supervision of a competent and appropriately qualified physician or 
other health care professional. 
14. Groups that are underrepresented in medical research should be provided appropriate access to 
participation in research. 
15. Physicians who combine medical research with medical care should involve their patients in 
research only to the extent that this is justified by its potential preventive, diagnostic or therapeutic 
value and if the physician has good reason to believe that participation in the research study will not 
adversely affect the health of the patients who serve as research subjects. 
16. Appropriate compensation and treatment for subjects who are harmed as a result of participating in 
research must be ensure 
C. RISKS, BURDENS AND RESULTS 
 
17. In medical practice and in medical research, most interventions involve risks and burdens.   
 
Medical research involving human subjects may only be conducted if the importance of the 
objective outweighs the risks and burdens to the research subjects. 
18. All medical research involving human subjects must be preceded by careful assessment of 
predictable risks and burdens to the individuals and groups involved in the research in comparison 
with foreseeable benefits to them and to other individuals or groups affected by the condition under 
investigation.   
Measures to minimize the risks must be implemented. The risks must be continuously monitored, 
assessed and documented by the researcher.  
19. Physicians may not be involved in a research study involving human subjects unless they are 
confident that the risks have been adequately assessed and can be satisfactorily managed.   

PROTOCOL:  OBG PED-001 VERSION 02

PAGE 45 OF 48

Kiora Pharmaceuticals, Inc. 
 
When the risks are found to outweigh the potential benefits or when there is conclusive proof of 
definitive outcomes, physicians must assess whether to continue, modify or immediately stop the 
study.    
D. VULNERABLE GROUPS AND INDIVIDUALS 
20. Some groups and individuals are particularly vulnerable and may have an increased likelihood of 
being wronged or of incurring additional harm.   
All vulnerable groups and individuals should receive specifically considered protection. 
21. Medical research with a vulnerable group is only justified if the research is responsive to the health 
needs or priorities of this group and the research cannot be carried out in a non-vulnerable group. In 
addition, this group should stand to benefit from the knowledge, practices or interventions that result 
from the research. 
E. SCIENTIFIC REQUIREMENTS AND RESEARCH PROTOCOLS 
22. 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 adequate laboratory and, as appropriate, animal experimentation. The welfare of 
animals used for research must be respected. 
23. The design and performance of each research study involving human subjects must be clearly 
described and justified in a research protocol.  The protocol should contain a statement of the ethical 
considerations involved and should indicate how the principles in this Declaration have been 
addressed.  
The protocol should include information regarding funding, sponsors, institutional affiliations, 
potential conflicts of interest, incentives for subjects and information regarding provisions for 
treating and/or compensating subjects who are harmed as a consequence of participation in the 
research study.  In clinical trials, the protocol must also describe appropriate arrangements for post-
trial provisions. 
F. RESEARCH ETHICS COMMITTEES 
24. The research protocol must be submitted for consideration, comment, guidance and approval to the 
concerned research ethics committee before the study begins. This committee must be transparent 
in its functioning, must be independent of the researcher, the sponsor and any other undue influence 
and must be duly qualified. It must take into consideration the laws and regulations of the country 
or countries in which the research is to be performed as well as applicable international norms and 
standards but these must not be allowed to reduce or eliminate any of the protections for research 
subjects set forth in this Declaration.  
The committee must have the right to monitor ongoing studies. The researcher must provide 
monitoring information to the committee, especially information about any serious AEs. No 
amendment to the protocol may be made without consideration and approval by the committee. 
After the end of the study, the researchers must submit a final report to the committee containing a 
summary of the study’s findings and conclusions. 
G. PRIVACY AND CONFIDENTIALITY

25. Every precaution must be taken to protect the privacy of research subjects and the confidentiality of 
their personal information.   
H. INFORMED CONSENT 
26. Participation by individuals capable of giving informed consent as subjects in medical research must 
be voluntary. Although it may be appropriate to consult family members or community leaders, no 
individual capable of giving informed consent may be enrolled in a research study unless he or she 
freely agrees. 
27. In medical research involving human subjects capable of giving informed consent, 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, post-study provisions and any other relevant aspects of 
the study. The potential subject must be informed of the right to refuse to participate in the study or 
to withdraw consent to participate at any time without reprisal. Special attention should be given to 
the specific information needs of individual potential subjects as well as to the methods used to 
deliver the information. 
After ensuring that the potential subject has understood the information, the physician or another 
appropriately qualified individual must then seek the potential subject’s freely-given informed 
consent, preferably in writing. If the consent cannot be expressed in writing, the non-written consent 
must be formally documented and witnessed.       
All medical research subjects should be given the option of being informed about the general 
outcome and results of the study. 
28. When seeking informed consent for participation in a research study the physician must be 
particularly cautious if the potential subject is in a dependent relationship with the physician or may 
consent under duress. In such situations the informed consent must be sought by an appropriately 
qualified individual who is completely independent of this relationship. 
29. For a potential research subject who is incapable of giving informed consent, the physician must 
seek informed consent from the legally authorised representative. These individuals must not be 
included in a research study that has no likelihood of benefit for them unless it is intended to promote 
the health of the group represented by the potential subject, the research cannot instead be performed 
with persons capable of providing informed consent, and the research entails only minimal risk and 
minimal burden. 
30. When a potential research subject who is deemed incapable of giving informed consent is able to 
give assent to decisions about participation in research, the physician must seek that assent in 
addition to the consent of the legally authorised representative. The potential subject’s dissent 
should be respected. 
31. Research involving subjects who are physically or mentally incapable of giving consent, for 
example, unconscious patients, may be done only if the physical or mental condition that prevents 
giving informed consent is a necessary characteristic of the research group. In such circumstances 
the physician must seek informed consent from the legally authorised representative. If no such 
representative is available and if the research cannot be delayed, the study may proceed without 
informed consent provided that the specific reasons for involving subjects with a condition that 
renders them unable to give informed consent have been stated in the research protocol and the study

has been approved by a research ethics committee. Consent to remain in the research must be 
obtained as soon as possible from the subject or a legally authorised representative. 
32. The physician must fully inform the patient which aspects of their care are related to the research. 
The refusal of a patient to participate in a study or the patient’s decision to withdraw from the study 
must never adversely affect the patient-physician relationship. 
33. For medical research using identifiable human material or data, such as research on material or data 
contained in biobanks or similar repositories, physicians must seek informed consent for its 
collection, storage and/or reuse. There may be exceptional situations where consent would be 
impossible or impracticable to obtain for such research. In such situations the research may be done 
only after consideration and approval of a research ethics committee. 
I. USE OF PLACEBO 
34. The benefits, risks, burdens and effectiveness of a new intervention must be tested against those of 
the best proven intervention(s), except in the following circumstances: 
Where no proven intervention exists, the use of placebo, or no intervention, is acceptable; or 
Where for compelling and scientifically sound methodological reasons the use of any intervention 
less effective than the best proven one, the use of placebo, or no intervention is necessary to 
determine the efficacy or safety of an intervention and the patients who receive any intervention less 
effective than the best proven one, placebo, or no intervention will not be subject to additional risks 
of serious or irreversible harm as a result of not receiving the best proven intervention.  
           Extreme care must be taken to avoid abuse of this option. 
J. POST-TRIAL PROVISIONS 
35. In advance of a clinical trial, sponsors, researchers and host country governments should make 
provisions for post-trial access for all participants who still need an intervention identified as 
beneficial in the trial. This information must also be disclosed to participants during the informed 
consent process. 
K. RESEARCH REGISTRATION AND PUBLICATION AND DISSEMINATION OF 
RESULTS 
36. Every research study involving human subjects must be registered in a publicly accessible database 
before recruitment of the first subject. 
37. Researchers, authors, sponsors, editors and publishers all have ethical obligations with regard to the 
publication and dissemination of the results of research. Researchers have a duty to make publicly 
available the results of their research on human subjects and are accountable for the completeness 
and accuracy of their reports. All parties should adhere to accepted guidelines for ethical reporting. 
Negative and inconclusive as well as positive results must be published or otherwise made publicly 
available. Sources of funding, institutional affiliations and conflicts of interest must be declared in 
the publication. Reports of research not in accordance with the principles of this Declaration should 
not be accepted for publication.

L. UNPROVEN INTERVENTIONS IN CLINICAL PRACTICE 
38. In the treatment of an individual patient, where proven interventions do not exist or other known 
interventions have been ineffective, the physician, after seeking expert advice, with informed 
consent from the patient or a legally authorised representative, may use an unproven intervention if 
in the physician's judgement it offers hope of saving life, re-establishing health or alleviating 
suffering. This intervention should subsequently be made the object of research, designed to 
evaluate its safety and efficacy. In all cases, new information must be recorded and, where 
appropriate, made publicly available.
