Background information 
NGF is a polypeptide discovered in the early 1950s by R. Levi Montalcini. NGF acts through 
specific high affinity (i.e., TrkA) and low affinity (i.e., p75NTR) NGF receptors which are 
expressed not only on nerve fibres but also on anterior segment of the eye (iris, ciliary body, 
lens, cornea and conjunctiva) and by the lacrimal gland providing the rationale for use of NGF 
in the treatment of diseases of the anterior segment of the eye. Murine NGF (mNGF) extracted 
and purified from the male mouse submaxillary gland was administered to over a hundred 
patients (45 published) with stage 2 and stage 3 neurotrophic keratitis (NK) in form of eye drops 
at a concentration of 200 µg/mL in balanced salt solution in two uncontrolled, unmasked, open-
label studies. Compelling results were observed with all affected eye(s) healed from persistent 
epithelial defects. Tolerability was good with only mild, local and transient side effects. As for 
dry eye disease, administration of NGF to dogs where dry eye had been surgically induced 
resulted in enhanced production and functional characteristics of tear film, with an associated 
improvement of ocular surface signs.  
Based on these data, the Company has developed a recombinant human NGF (rhNGF) 
expressed in E. coli for treatment of NK.

A phase I, masked placebo controlled clinical study in 74 healthy volunteers after single and 
multiple dose of different concentrations of rhNGF eye drops showed a safety profile rhNGF 
eye drops (Study NGF0112). A Phase I/II multicentre, double-masked, vehicle controlled study 
to evaluate the safety and efficacy of rhNGF at 10 and 20 μg/mL six times a day in 174 patients 
with stage 2 and 3 NK (study NGF0212) has been completed in 2015 demonstrating that rhNGF 
was very well tolerated also in patients with NK. 
In addition to NK, rhNGF, in the same formulation (containing L-methionine) proposed for the 
present study, has been evaluated in a Phase I/II study in retinitis pigmentosa (RP) patients at 
the doses of 60 and 180 μg/mL, and in a phase II study in neurotrophic keratitis patients at the 
same concentration of the present study, 20 μg/mL (6 times a day). 
An open uncontrolled study showed that 4 weeks treatment with rhNGF eye drops at 20 μg/mL 
and 4 μg/mL) concentrations was safe and effective in improving symptoms, corneal staining 
and tear function in patients with dry eye as compared to baseline (NGF0213). 
Study Design and Methodology  
The proposed phase II study is a single-centre, randomized, double masked, parallel arm, 
vehicle-controlled trial, designed to evaluate the preliminary efficacy and safety of rhNGF eye 
drops at 20 µg/ml concentration administered six times daily for 8 weeks in patients who 
underwent cataract and corneal refractive surgery, both known to damage the corneal sensory 
nerve plexus. 
After confirmation of inclusion and exclusion criteria all eligible patients will be randomized 
at 2:1 ratio to rhNGF or vehicle control treatment with 8 weeks of study treatments 
administration with 4 weeks Follow-up. 
 
 
 
  
 
 
Treatment: either rhNGF eye drops 20 µg/ml or vehicle six times daily for 8 weeks.  
Follow-up: 4 weeks with no further treatment except artificial tears (use recorded in drops/day). 
After baseline (day 0), enrolled patients will be evaluated for safety and efficacy at week 4 (day 
282), week 8 (day 562) or early exit and at 4 weeks (day 842) after the end of study 
treatment.

Treatment Groups  
Eligible patients will be randomized to either rhNGF eye drops 20 µg/ml or vehicle:  
Group 1: rhNGF 20 µg/mL: One drop (40 µL) corresponding to 0.80 µg of rhNGF will be 
instilled into each eligible eye six times a day (every 2h), for a total daily dose of 9.6 µg (both 
eyes, if applicable), for 56 consecutive days.  
Group 2: Vehicle: One drop (40 µL) will be instilled into each eligible eye six times a day 
(every 2h). 
In all patients, both eyes will be treated, if meet the eligibility criteria. If only one eye is eligible, 
then only that eye will be treated. 
In the 4 week follow up no further treatment is planned except artificial tears, per Investigator 
decision. Administration of such medications will be recorded in eCRF (number of drops per 
day). 
Primary Objective 
The primary objective of this study is to assess efficacy and safety of rhNGF when administered 
as eye drops to patients after cataract and refractive surgery. 
Study end-points 
Clinical efficacy and safety parameters will be evaluated at each time point (days 0, 28±2, 56±2 
and 28±2 days after discontinuation of treatment) with the following endpoints: 
Primary efficacy end-point: 
 Change from baseline in SANDE scores for severity and frequency assessed at 8 weeks of 
treatment  
Co-primary Efficacy Endpoint 
 Changes in Cornea vital staining with fluorescein (National Eye Institute [NEI] scales) 
assessed at 8 weeks of treatment 
Secondary efficacy end-points: 
 Changes Conjunctiva vital staining with fluorescein (National Eye Institute [NEI] scales) 
 Changes in Tear Film Break-Up Time (TFBUT) 
 Changes in Cochet-Bonnet corneal aesthesiometry 
 Changes in Nerve count and morphology at scanning laser in vivo corneal confocal 
microscopy (only patients who had LASIK surgery) 
 Changes in SANDE scores (face values) for severity and frequency

Safety end-point: 
 Incidence and frequency of Treatment-Emergent Adverse Events (TEAEs), assessed 
throughout the study 
Details of efficacy and safety analyses will be presented in the Statistical Analysis Plan finalised 
before Database Lock. 
Number of Subjects 
In total 180 post cataract or refractive surgery patients will be enrolled in the study with 120 
patients to be treated with rhNGF and 60 patients treated with vehicle. 
Sample size calculation 
Sample size  was calculated by assuming at single eye level a mean difference from baseline 
mean SANDE scores of -30±20 in the rhNGF groups versus -20±20 in vehicle group (80% 
power, alpha =0.05; 2-sided test), considering that the active comparator has already proven 
safe and effective in dry eye patients. The sample size has been calculated based on a 2:1 
randomization by the following  formula:  
n1 = (0.5) × n × (1 + k) 
n2 = (0.5) × n × (1 + (1/k)) 
with n1= active treatment and n2= vehicle and n= 63 and k= n1 /n2 = 2/1=2. Therefore n1= 
94,5 and n2=47.25.  Assuming a 5% drop out rate, a total of 100 patients will be enrolled in 
active arm and 50 in the vehicle arm. This calculation is based on one study eye per patient. 
Whereas also two study eyes per patient may occur, that will increase power to above 80%). 
 
However, in order to provide the mean of detecting a significant difference also on a clinical 
sign of the effect of the rhNGF therapy (namely Co-primary Efficacy Endpoint cornea and 
conjunctiva vital staining with fluorescein (National Eye Institute [NEI] scales)), sample size 
calculation was also performed by assuming, at single eye level, a mean difference from 
baseline in Cornea NEI scale scores of -3.9±2.2 in the rhNGF groups versus -2.9±2.2 in vehicle 
group (80% power, alpha =0.05; 2-sided test), considering that the active comparator has 
already proven safe and effective in dry eye patients. The sample size has been calculated based 
on a 2:1 randomization by the following formula:  
n1 = (0.5) × n × (1 + k) 
n2 = (0.5) × n × (1 + (1/k)) 
with n1= active treatment and n2= vehicle and n= 76 and k= n1 /n2 = 2/1=2. Therefore n1= 114 
and n2=57.  Assuming a 5% drop out rate, a total of 120 patients will be enrolled in active arm 
and 60 in the vehicle arm. This calculation is based on one study eye per patient. Whereas also 
two study eyes per patient may occur, that will increase power to above 80%). 
 
Considering the two calculations performed to determine the sample size, in this study will be 
enrolled 180 patients (120 patients enrolled in active arm and 60 in the vehicle arm) in order to 
detect both changes at the same time in the variables. 
 
No adjustment for multiplicity has been made considering that rhNGF efficacy is to be 
evaluated on the contemporaneous change of both variables (see ICH-E9)

 INTRODUCTION 
1.1 
Background Information 
 
Nerve growth factor - overview 
Nerve growth factor (NGF) is a polypeptide essential for the survival and growth of sympathetic 
and sensory neurons and for differentiation of neurons in the central nervous system. It binds 
with at least two classes of receptors: TrkA, a transmembrane tyrosine kinase and p75 LNGFR 
(for "low-affinity nerve growth factor receptor") often abbreviated as p75NTR. 
NGF and TrkA are expressed in the anterior segment of the eye (iris, ciliary body, lens, cornea 
and conjunctiva), and NGF is released in the aqueous humour. Several pieces of experimental 
evidence suggest that NGF affects all tissues of the anterior ocular segments, playing a crucial 
role in the physiopathology of several anterior ocular segment diseases. 
 
Chemical and formulation data 
As recombinant human NGF (rhNGF) production in mammalian cells does not achieve 
adequate yields, a manufacturing process based on the use of recombinant Escherichia coli has 
been developed. However, because the biological activity of NGF relies on the formation of 
three disulphide bonds and because disulphide bonds cannot occur in the reducing cytosol, the 
purification and renaturation of NGF produced in E.coli is problematic. Based on the 
knowledge that the prosequence increases the yield and rate of refolding of NGF, we have 
developed a manufacturing process starting from pro-NGF. After expression of pro-NGF in E. 
coli, the insoluble protein is isolated in the form of insoluble inactive aggregates (inclusion 
bodies), solubilised in a strong denaturing agent and subsequently converted into the natural 
conformation, which is determined by the disulphide bridges present in the natural NGF. 
Biologically active rhNGF is finally obtained by splitting off the prosequence by enzymatic 
cleavage. The DNA sequence of human proNGF has been optimized for E coli expression 
(codon adjustment) and two changes in the furin cleavage site, R101V and K103A, have been 
introduced. These two changes are important to ensure a homogeneous rh-NGF preparation 
during the process with the mature protein starting with Serine 105. 
The Investigational Medicinal Product (IMP) consists of a sterile isotonic solution for ocular 
administration (containing L-methionine as excipient), containing rhNGF at 20 µg/mL i.e. 
0.020 mg/mL) as drug substance.  
 
Previous experience in humans with rhNGF 
NGF acts through specific high affinity (i.e., TrkA) and low affinity (i.e., p75NTR) NGF 
receptors which are expressed not only on nerve fibres but also on anterior segment of the eye 
(iris, ciliary body, lens, cornea and conjunctiva) and by the lacrimal gland providing the 
rationale for use of NGF in the treatment of diseases of the anterior segment of the eye. Murine 
NGF (mNGF) extracted and purified from the male mouse submaxillary gland was 
administered to over a hundred patients (45 published) with stage 2 and stage 3 neurotrophic

keratitis (NK) in form of eye drops at a concentration of 200 µg/mL in balanced salt solution in 
two uncontrolled, unmasked, open-label studies. Compelling results were observed with all 
affected eyes healed from persistent epithelial defects. Tolerability was good with only mild, 
local and transient side effects. As for dry eye disease, administration of NGF to dogs where 
dry eye had been surgically induced resulted in enhanced production and functional 
characteristics of tear film, with an associated improvement of ocular surface signs. 
Based on these data, Dompé has developed a recombinant human NGF (rhNGF) expressed in 
E. coli for treatment of NK. 
A phase I, masked placebo controlled clinical study in 74 healthy volunteers after single and 
multiple dose of different concentrations of rhNGF eye drops showed a safety profile rhNGF 
eye drops (Study NGF0112). A Phase I/II multicentre, double-masked, vehicle controlled study 
to evaluate the safety and efficacy of rhNGF at 10 and 20 μg/mL six times a day in 174 patients 
with stage 2 and 3 NK (study NGF0212) has been completed in 2015 demonstrating that rhNGF 
was very well tolerated also in patients with NK. 
In addition to NK, rhNGF, in the same formulation (containing L-methionine) proposed for the 
present study, has been evaluated in a Phase I/II study in retinitis pigmentosa (RP) patients at 
the doses of 60 and 180 μg/mL and in a phase II study in neurotrophic keratitis patients at the 
same concentration of the present study, 20 μg/mL (6 times a day). 
An open uncontrolled study showed that 4 weeks treatment with rhNGF eye drops at 20 μg/mL 
and 4 μg/mL) concentrations was safe and effective in improving symptoms, corneal staining 
and tear function in patients with dry eye as compared to baseline (NGF0213). 
1.2 
Study Rationale 
The data reported above, together with the evidence of rhNGF eye drop effectiveness in the 
treatment of patients affected by corneal ulcers and dry eye disease make rhNGF a strong 
candidate for the treatment of patients who underwent cataract and corneal refractive surgery, 
both known to damage the corneal sensory nerve plexus. 
As part of the development plan to evaluate the potential efficacy of the rhNGF solution, the 
present exploratory study was designed in order to further evaluate the potential efficacy and 
safety of rhNGF eye drops in this population of patients. 
For additional information regarding the development of rhNGF, please consult the current 
Investigator Brochure. 
 
Dose and Schedule Rationale 
The dose proposed for this trial is 20 µg/mL (1 drop/eye, six times daily for 8 weeks). 
In previous studies with Dompé rhNGF in human volunteers, the compound has been 
administered in a wide range of doses after single and multiple administrations up to 180 µg/mL 
(three times daily for five days, one eye).  
In the Phase I/II of the NK studies (NGF0212 and NGF0214), rhNGF administered at 20 µg/mL 
(six times daily for 8 weeks, one eye) demonstrated to be safe and well tolerated at this dose 
regime.

Risks and benefits 
In the present study, potential risks of multiple rhNGF applications to post cataract and 
refractive surgery patients are expected not to surpass in frequency the adverse reactions and 
the untoward effects reported in the Phase I study (NGF0112). 
The post cataract and refractive surgery patients participating in this study may potentially 
benefit from the application of rhNGF for 56 days and restoration of the damages to the corneal 
sensory nerve plexus associated with the surgery.

 STUDY OBJECTIVES 
The primary objective of this study is to assess the preliminary efficacy and safety of rhNGF 
when administered as eye drops to patients who underwent cataract and corneal refractive 
surgery. 
2.1 
Primary efficacy end-point 
Following refractive surgery, due to the iatrogenic surgical damage to corneal sensory nerves, 
a variable percentage of patients complain of dry eye symptoms that often do not correlate with 
specific ocular surface signs. 
Therefore, a validated symptoms' questionnaire has been chosen to assess the preliminary 
efficacy of rhNGF eye drops in this clinical trial. 
The two-item SANDE (Symptom Assessment in Dry Eye) is a validated questionnaire that has 
been widely reported to be quick, easy to perform for patients, and equally efficacious in scoring 
dry eye symptoms compared with the Ocular Surface Disease Index (OSDI), another validated 
questionnaire based on 12 questions that is commonly used in clinical trials on dry eye patients. 
However, while OSDI is designed for ocular surface disease in general, the SANDE 
questionnaire is designed specifically for dry eye symptoms, which are those commonly 
reported after corneal and refractive surgery procedures, including cataract surgery. 
 
Preliminary evaluation of the clinical efficacy throughout the study on the basis of the following 
symptoms assessment: 
 Change from baseline in SANDE scores for severity and frequency assessed at 8 weeks of 
treatment  
 Assessments of SANDE score will be performed on days 0, 28±2, 56±2 and 28±2 days 
after discontinuation of treatment. 
 
Co-primary efficacy end-point 
Preliminary evaluation of the clinical efficacy throughout the study on the basis of the following 
sign assessment: 
 Changes in Cornea vital staining with fluorescein (National Eye Institute [NEI] scales) 
assessed at 8 weeks of treatment 
2.2 
Secondary efficacy end-points 
Additional evaluation of the clinical efficacy throughout the study will be performed on the 
basis of the following assessments: 
 Changes in Cornea and conjunctiva vital staining with fluorescein (National Eye Institute 
[NEI] scales) 
 Changes in Tear Film Break-Up Time (TFBUT)

Storage and handling 
The Pharmacist and/or Investigator will be responsible for receipt, proper storage and usage of 
study drug.  
The investigational product must be stored at -20 ± 5 °C at the Investigational sites, in an 
appropriate locked room accessible only to the pharmacist, the Investigator or a duly designated 
person.  
A temperature probe and data logger will accompany the drug on shipment. It is essential that 
the Investigational sites will verify the temperature excursion during shipment vs. the 
acceptable storage conditions, in order to identify potential stability concerns during shipment. 
These must be immediately communicated to the Sponsor that will decide upon appropriate 
actions to be taken. The IMP will be stored in a locked place, sheltered from light. The vials 
will be not shaken since agitation of vials may cause foaming and/or particle formation.  
On Day 0 and at Week 4 visits the patients will receive from the study personnel 4 weekly 
boxes containing the study medications in a refrigerated bag. The refrigerated bag will be used 
to ensure that the medications will maintain refrigeration temperatures during transport to the 
patient’s home.  
Patient should bring the study medication, one monthly box containing 4 weekly kits, at home 
as soon as possible and immediately store it in a freezer at -20 ± 5 °C. 
The weekly kit in use must be kept at 2-8°C for 7 days, the daily vial can be kept at room 
temperature before the patient will use the single vial for each instillation (both eye) as far as 
12 hours are not exceeded.  
Together with the IMP weekly box, the patients will be provided with a sufficient number of 
syringes and adaptors to be used for the administration of the IMP for the following 4 weeks. 
Syringes and adaptors will be provided separately in single sterile PE packages and may be kept 
at room temperature. 
The syringe is used with an adaptor consisting of a connecting device with dual connections: 
one end for the syringe and one end for the vial. Patients will need to:

1) put the adaptor on the top of the vial (after removing the plastic seal) by piercing the 
septum 
2) put the syringe on adaptor inlet 
3) draw the solution contained in the vial with the syringe until this reaches its 
predetermined capacity 
4) remove the syringe and use it as a dropper to administer one drop of IMP into each eye 
5) the syringe must be discharged after each administration to both eyes, if applicable 
3.3 
Drug accountability 
After receipt of the IMP supply, the pharmacist and/or Investigator will confirm in writing by 
signing and dating standard drug accountability forms. 
Every four weeks from the start of the treatment the patients will return the used or unused 
study boxes to the Investigator.  
The Pharmacist and/or Investigator, who will keep a cumulative inventory and dispensing 
records, will maintain all supplies under adequate security.  
The Investigator will maintain an accurate record about the shipment and dispensing of the test 
drug, using a drug accountability ledger. An accurate drug disposition record will be kept 
specifying the date and amount dispensed to each patients.  
Adequate record of receipt, use, return or loss of drug will be retained. This inventory record 
must be available for inspection by the Sponsor and regulatory inspection at any time. Copies 
of this record will be provided to the Sponsor by the CRO at the conclusion of the study. 
At each scheduled visit the diary should be reviewed with the patient for completeness. Missing 
information should not be provided during the diary check but reported as missing 
Partially used or unused study drug boxes will be returned to the Sponsor, at the end of the 
study.  
At the conclusion of the study, and if appropriate during the course of the study, the Investigator 
will complete the drug accountability forms. Within one month after completion of the trial the 
unused study medication will be shipped to the Sponsor or will be destroyed after authorisation 
by the Sponsor by an authorised company according to GCP regulations.

 DESCRIPTION OF SPECIFIC PROCEDURES 
7.1 
Ophthalmological Evaluations 
Ocular evaluations will be performed on both eyes even if just one eye is eligible (determined 
as study eye). The assessments must always be performed according the sequence detailed in 
Par 6.1. The assessment will be performed at Day 0 Baseline Visit, Week 4 Visit, Week 8 Visit 
and at Week 12 Visit.  The ophthalmological assessment will include: 
 
External Ocular Examination 
External Ocular Examination assesses the motility of the extraocular muscles and the 
appearance and function of the eyelids before the instillation of any dilating or anaesthetic eye 
drops. 
 
Symptom Assessment in Dry Eye (SANDE): 
The Symptom Assessment in Dry Eye (SANDE) questionnaire is a short questionnaire to 
evaluate both dry eye intensity and frequency by using a 100 mm VAS. The patient symptoms 
of ocular dryness and/or irritation will be quantified on the scale based on two questions that 
assess both severity and frequency of symptoms. A VAS is a measurement instrument that tries 
to measure a characteristic or attitude that is believed to range across a continuum of values and 
cannot easily be directly measured. For example, the amount of irritation that a patient feels 
ranges across a continuum from none to an extreme amount of irritation. From the patient's 
perspective this spectrum appears continuous (i.e. their irritation does not take discrete jumps, 
as a categorization of none, mild, moderate and severe would suggest). It was to capture this 
idea of an underlying continuum that the VAS was devised.  
For the assessment, the patients mark on the 100 mm VAS line the point that they feel represents 
their perception of their current state. The VAS score is determined by measuring in millimetres 
from the left hand end of the line to the point that the patient marks. The SANDE scores will 
be then evaluated for the 2 questions severity (0-100) and frequency (0-100). Note: the 
AVERAGE value of severity and frequency scores will be used for verifying inclusion 
criterion #2 at Day 0 visit. 
 
Best corrected distance visual acuity (BCDVA):  
Refraction and visual acuity measurements will be performed for all patients by trained vision 
examiners only. Refraction should be conducted prior to visual acuity testing to obtain best-
corrected vision as described below. Best-corrected visual acuity is measured at Day 0 Baseline 
Visit, Week 8 Visit and at Week 12 Visit using standard charts, lighting, and procedures. Best 
correction is determined by careful refraction at that visit according to the standard protocol for 
refraction as described below.

Equipment 
Refraction equipment required includes:  
 Retroilluminated Light box and ETDRS 4 metre distance acuity chart set  
 Trial lens frames 
 Trial lens set with plus or minus cylinder lenses  
 Jackson cross-cylinders of 0.25, 0.50, and 1.00 diopters  
 Pinhole occluder 
 Tissues or eye pads and tape  
 A 1 metre rigid measuring stick 
 
Visual acuity charts: Chart 1 is used for testing the visual acuity of the RIGHT eye; Chart 2 for 
testing the LEFT eye; and Chart R (or 3) for refraction only. Patients should not be allowed to 
see any of the charts before the examination.  
A distance of 4 metres is required between the patient’s eyes and the visual acuity chart. With 
the box light off, not more than 15 foot-candles of light (161.4 Lux) should fall on the centre of 
the chart. To measure the amount of light, the room is set up for visual acuity testing, but with 
the box light off. The light metre is placed at the fourth line from the top of the chart, with its 
back against the chart and the reading is taken. If more than one line available for testing visual 
acuity, the visual acuity of an individual patient should be measured in the same line at each 
visit, if possible. If different lines are used to test visual acuity, they must each meet the same 
standards.  
Retroilluminated ETDRS charts are used in this trial. The illuminator box will be either wall-
mounted or mounted on a stand. The light box should be mounted at a height such that the top 
of the third row letter is 49 + 2 inches from the floor.  
The visual acuity light box is equipped with two General Electric 20-watt fluorescent tubes and 
ballast. Each tube is partly covered by a 14-inch fenestrated sleeve, which is centred on the tube 
and open in the back. This serves as a “baffle” to produce even illumination over the testing 
chart. Because the illumination of fluorescent tubes diminishes by 5 percent during the first 100 
hours and by another 5 percent during the next 2000 hours, new tubes should be kept on for 4 
days (96 hours) continuously, and should be replaced once a year. 
A sticker should be placed on the back of the light box, indicating the date when the present 
tubes were installed. A spare set of burned in bulbs should be available on site.  
Detailed instructions for VA assessment 
As a reminder, Charts 1, 2 and R (or 3) are used for testing the right eye, left eye, and refraction, 
respectively. Patients should not see the charts until the test begins. The lens correction from 
the patient’s refraction should be in the trial frame worn by the patient.  
All eyes must be tested at 4 metres first, even if the refraction was performed at 1 metre.  
The patient should be seated comfortably directly in front of the chart so that the eyes remain 
at the 4 metre distance. Testing always begins with the right eye. The fellow eye should be 
occluded with a folded tissue or eye pad lightly taped over the eye behind the trial frame serves 
as an effective occluder that allows eccentric fixation without inadvertent use of the covered

eye. After testing the right eye, occlusion of the right eye should be done BEFORE Chart 2 is 
put up for testing the left eye.  
The patient is asked to read the letters slowly, approximately one letter per second. The patient 
should be told that only one chance is given to read each letter, but may change their mind 
before moving to the next letter. If the patient is unsure about the identity of the letter, then the 
patient should be encouraged to guess.  
The patient should begin by reading the top line of the chart and continue reading every letter 
on each smaller line, from left to right on each line. The patient should be encouraged to 
continue reading even if making mistakes. Each letter read is counted. The examiner circles 
every correct letter read and totals each line and the whole column (0 if no letters are correct) 
on the provided VA worksheet. An X is put through letters read incorrectly. Letters, for which 
no guess was attempted, are not marked. When a patient reaches a level where he/she cannot 
guess, the examiner may stop the test, provided that the patient has made errors on previous 
guesses, which is a clear indication that the best visual acuity has been obtained.  
When a patient cannot read at least 20 letters on the chart at 4 metres, the patient is tested at 1 
metre. The distance from the patient to the chart should be measured again using the rigid one 
metre stick. The distance is measured from the outer canthus to the centre of the fourth letter 
(right eye) or the second letter (left eye) of the third line of the chart. The spherical correction 
in the trial frame should be changed by adding +0.75 to correct for the closer test distance. The 
patient may fixate eccentrically or turn or shake his/her head to improve visual acuity. Particular 
care should be taken to make sure the patient does not move forward when testing at 1 metre. 
The patient should be reminded to blink. 
The examiner should not tell the patient if a letter was identified correctly. The patient may be 
encouraged by neutral comments, such as “good,” “next,” and “OK.”  
The examiner should not stand close to the chart during testing. Attention should be focused on 
the patient and the VA worksheet. If the patient has difficulty locating the next line to read, the 
examiner may go up to the chart and point briefly to the next line to be read, but then must 
move away from the chart.  
When 20 or more letters are read at 4 metres the visual acuity score for that eye is recorded as 
the number of letters correct at 4 metres plus 30 (refer to the VA worksheet). The patient gets 
credit for the 30 letters at 1 metre even though they did not have to read them. Otherwise, the 
visual acuity score is the number of letters read correctly at 1 metre plus the number, if any, 
read at 4 metres. If no letters are read correctly at either 4.0 metres or 1 metre, then the visual 
acuity score is recorded as “0.” 
 
Slit-lamp examination (SLE) 
The slit lamp examination must be performed before the instillation of any dilating or anesthetic 
eye drops or the fluorescein agent. 
The patient will be seated at the slit lamp while being examined. Eyelids, lashes, conjunctiva, 
cornea, lens, iris and anterior chamber will be evaluated.

Tear Film Break Up Time (TFBUT)  
TFBUT will be measured by determining the time to tear break-up. The TFBUT will be 
performed after instillation of 5 l of 2% sodium fluorescein solution into the inferior 
conjunctival cul-de-sac of each eye. The patient will be instructed to blink several times to 
thoroughly mix the fluorescein with the tear film. In order to achieve maximum fluorescence, 
the examiner should wait approximately 30 seconds after instillation before evaluating TFBUT. 
With the aid of a slit lamp at 10X magnification using cobalt blue illumination, the examiner 
will monitor the integrity of the tear film, noting the time it takes to form lacunae (clear spaces 
in the tear film) from the time that the eye is opened after the last blink. This measurement will 
be performed within 10 seconds maximum. The TFBUT will be measured twice during the first 
minute after the instillation of the fluorescein. If the 2 readings differ by more than 2 seconds a 
third reading is taken.  
The TFBUT value will be the average of the 2 or 3 measurements. 
Relevant TFBUT findings will be entered in the eCRF. 
 
Corneal sensitivity  
For the assessment of corneal sensation the Luneau Cochet-Bonnet aesthesiometer (Western 
Ophthalmics Corporation©) should be used. 
The Cochet-Bonnet aesthesiometer contains a thin, retractable, nylon monofilament that 
extends up to 6 cm in length. Variable pressure can be applied to the cornea by adjusting the 
monofilament length. The monofilament length ranges from 6 to 0.5 cm. As the monofilament 
length is decreased the pressure increases from 11 mm/g to 200 mm/g.  
Corneal sensation will be measured in both eyes in each of the four quadrants of the cornea 
using the Cochet Bonnet aesthesiometer before the instillation of any dilating or anesthetic eye 
drops.  
Steps for using the Cochet Bonnet aesthesiometer: extend the filament of the aesthesiometer to 
full length of 6 cm. Slowly advance the monofilament towards the eye until the tip 
perpendicularly touches the corneal surface. Continue to exert a slight pressure until obtaining 
an inflection deviation of the filament of about 4% (i.e. the first visible inflection). If a positive 
reaction to the touch of cornea is elicited proceed to step 3. If a positive reaction is not achieved 
proceed to step 2. (NOTE: A positive response is any action indicating corneal sensation 
whether communicated verbally or physically).  
Retract the filament incrementally in 0.5 cm and repeat this step until the patient gives a positive 
reaction indicating that the contact of the monofilament on the cornea has been sensed. (NOTE: 
The shorter filament lengths indicate decreased corneal sensation). 
Record the length of the filament in cm at which the patient sensed the contact with the cornea. 
Repeat steps 1-3 in each of the 4 corneal quadrants (superior nasal, inferior nasal, superior, 
temporal and inferior temporal) in the study eye(s) and in each of the 4 corneal quadrants of the 
other eye (not the study eye, if applicable).  
To clean the instrument, please refer to your national standards for devices that contact the eye 
and tears or follow the suggested manufacturer’s recommendations.

The length of the filament in cm at which the patient corneal sensation was observed for the 
tested area of the cornea will be entered into the eCRF.  
Corneal sensitivity findings will be entered in the eCRF. 
 
Ocular surface staining (NEI score) 
As grading scale of the corneal and conjunctiva damage, the NEI/Industry Workshop guidelines 
will be used. The cornea is divided into five sectors (central, superior, inferior, nasal and 
temporal), each of which is scored on a scale of 0–3, with a maximal score of 15. Both nasally 
and temporally, the conjunctiva is divided into a superior paralimbal area, an inferior paralimbal 
area and a peripheral area with a grading scale of 0–3 and with a maximal score of 9 for the 
nasal and temporal conjunctiva.  
Ideally the grading should be performed between one and four minutes after staining. For a 
better reading it is also essential not to use an intense illumination beam, which may reduce the 
contrast and lead to an underestimation of grading 
 
Corneal confocal microscopy (only for patients who underwent LASIK 
surgery) 
In vivo scanning confocal microscopy will be performed bilaterally in the central cornea to 
more closely examine the corneal epithelium, sub-basal nerve plexus, stroma and endothelium 
with particular attention given to the presence and density of corneal nerves. Prior to the 
procedure patients will be treated with anesthetic drops and a viscoelastic liquid gel will be 
applied to the cornea as an immersion substance for the microscope lens.

ASSIGNMENT OF STUDY TREATMENT 
8.1 
Randomization 
After obtaining informed consent a consecutive screening number will be assigned to each 
patient according to the sequence of study entry, from S001 onwards (S002, S003 etc.). After 
confirming eligibility for the study, patient will be randomized (2:1 to rhNGF eye drops solution 
at 20 µg/ml (120 patients) or vehicle eye drops solution (60 patients) to be administered 6 times 
per day per study eye (or both eyes if applicable) for 8 weeks) and allocated with a consecutive 
randomization number of the randomization list starting with 001 onwards (002, 003 etc.). 
8.2 
Treatment allocation 
After successful completion of screening each eligible patient will be assigned a patient number 
(randomization number) according to the sequence of study entry (randomization), from 001 to 
180. Drop outs will not be replaced after randomization. 
8.3 
Masking 
For the whole duration of the trial treatments will be unknown to the patient, the Investigator 
and the site staff. The identity of the treatments will remain unknown to the patient, Investigator, 
site staff and Sponsor’s clinical research personnel until the study is unmasked for the final 
statistical analysis (data base lock) except in case of specific events that will require unmasking 
of the patient. 
The vials of rhNGF (20 µg/ml) and the vials containing the vehicle of rhNGF will be identical 
in appearance and the contents of the vials will be indistinguishable. All staff who is directly 
involved in the analysis of study results will remain masked to treatment assignments while the 
study is in progress. 
A list of sequential kit numbers will be generated by a member of the CRO SAS programming 
group not involved in the conduct of the study. Each kit number will be randomly associated 
with a treatment group. Patients will be assigned to treatment in numerical order. A tear-off 
label from the kit box, with the kit number, will be attached to the investigational product 
dispensing log. 
If the Investigator becomes unmasked for any reason, this information will be recorded on 
source data and in the eCRF of the study, specifying the date and the reason.  
In the event of a medical emergency where the knowledge of patient treatment is required to 
provide the patient with appropriate care, Investigators will have the possibility to unmask the 
treatment assignment for a specific patient.  If there is sufficient time, the Investigators are 
encouraged to contact the CRO staff to discuss individual case before unmasking concerned 
patient.

STATISTICAL METHODS 
The data documented in this study will be summarized using descriptive summary statistics, 
i.e. arithmetic mean, SD, CV (%), minimum, median and maximum values for quantitative 
variables, and frequencies for qualitative variables. In case a patient has two study eyes, its 
quantitative efficacy data will be regarded as within subject duplicates, allowing more precise 
patient values as well as the splitting of the SD into a within-subject and between-subject 
component. 
The statistical analysis will be performed using SAS® version 9.1.3 Service Pack 4 for 
Windows® or higher.  
A statistical analysis plan (SAP) will be issued before database lock and de-masking. Final 
statistical analysis on the study primary, co-primary and secondary variables will be presented 
in detail in the SAP.  
10.1 
Analysis Sets 
 
Definitions 
A patient will be defined as screened after the signature of the informed consent, regardless of 
the completion of all the screening procedures. 
A patient will be defined as eligible if he/she meets all the inclusion criteria and dose not fulfil 
any of the exclusion criteria for at least one eye (defined as study eye). Otherwise he/she will 
be defined as a screen failure.  
A patient will be defined as enrolled in the study if he/she is randomized.  
 Enrolled set: all enrolled patients.  
 Safety Set (SAF): all enrolled patients who receive at least one dose of the investigational 
medicinal product(s) at the study eye(s). This analysis set will be used for demographic, 
baseline and background characteristics and the safety analysis 
 Full Analysis Set (FAS): all patients in the SAF, who have at least one post-baseline 
efficacy measurement. This analysis set will be used for the primary and co-primary 
efficacy analysis. 
 Per Protocol set (PP): all patients in the FAS who fulfil the study protocol requirements in 
terms of investigational medicinal product intake and collection of primary and co-primary 
efficacy data and with no major deviations that may affect study results. This analysis set 
will be used for supportive efficacy analysis 
Each patient will be coded by the CRO Biometry Unit as valid or not valid for the Enrolled Set, 
SAF, FAS and PP. Patients will be evaluated according to the treatment they will actually 
receive. 
 
Reasons for exclusion from the Full Analysis Set 
Reasons for the exclusion from the Full Analysis Set are the following:

 
failure to take at least one dose of the IMP at any study eye 
 
lack of any efficacy data post enrolment 
 
failure to satisfy major inclusion/exclusion criteria (eligibility violations). Patients who fail 
to satisfy an inclusion/exclusion criterion may be excluded from the analysis without the 
possibility of introducing bias only under the following circumstances: 
 
the inclusion/exclusion criterion was measured prior to enrolment 
 
the detection of the relevant eligibility violations can be made completely 
objectively 
 
all detected violations of the particular inclusion/exclusion criterion are excluded 
 
Reasons for exclusion from the Per Protocol set 
Reasons for the exclusion from the Per Protocol set will be determined in the Blind Data Review 
Meeting and can be the following: 
 
lack of compliance with IMP administration (see § 10.3) 
 
exposure to an IMP dose different from the one assigned to the patient 
 
missing primary or co-primary efficacy data 
 
failure to satisfy any inclusion/exclusion criteria (eligibility violations) 
 
intake of prohibited medications 
10.2 
Sample size and power considerations 
Sample size was calculated by assuming at single eye level a mean difference from baseline 
mean SANDE scores of -30±20 in the rhNGF groups versus -20±20 in vehicle group (80% 
power, alpha =0.05; 2-sided test), considering that the active comparator has already proven 
safe and effective in dry eye patients. The sample size has been calculated based on a 2:1 
randomization by the following formula:  
n1 = (0.5) × n × (1 + k) 
n2 = (0.5) × n × (1 + (1/k)) 
with n1= active treatment and n2= vehicle and n= 63 and k= n1 /n2 = 2/1=2. Therefore n1= 
94,5 and n2=47.25.  Assuming a 5% drop out rate, a total of 100 patients in the active arm and 
50 in the vehicle arm are required. This calculation is based on one study eye per patient. 
Whereas also two study eyes per patient may occur, that will increase power to above 80%). 
 
However, in order to provide the mean of detecting a significant difference also on a clinical 
sign of the effect of the rhNGF therapy (namely Co-primary Efficacy Endpoint cornea vital 
staining with fluorescein (National Eye Institute [NEI] scales)), sample size calculation was 
also performed by assuming, at single eye level, a mean difference from baseline in Cornea NEI 
scale scores of -3.9±2.2 in the rhNGF groups versus -2.9±2.2 in vehicle group (80% power, 
alpha =0.05; 2-sided test), considering that the active comparator has already proven safe and 
effective in dry eye patients. The sample size has been calculated based on a 2:1 randomization 
by the following formula:  
n1 = (0.5) × n × (1 + k)

n2 = (0.5) × n × (1 + (1/k)) 
with n1= active treatment and n2= vehicle and n= 76 and k= n1 /n2 = 2/1=2. Therefore n1= 114 
and n2=57.  Assuming a 5% drop out rate, a total of 120 patients in active arm and 60 in the 
vehicle arm are required. This calculation is based on one study eye per patient. Whereas also 
two study eyes per patient may occur, that will increase power to above 80%). 
 
Considering the two calculations performed to determine the sample size, in this study will be 
enrolled 180 patients (120 patients enrolled in active arm and 60 in the vehicle arm) in order to 
detect both changes at the same time in the variables. 
 
 
10.3 
Compliance with IMP administration 
The assessment of patients’ compliance to the IMP will be made by determining the number of 
study medication vials dispensed to the patient at Day 0 baseline Visit, Week 4 Visit and the 
number of unused study medication vials returned at Week 4 Visit and Week 8 Visit, 
respectively. Compliance will be evaluated according to the following formula: 
 
 treatment
on
 
days
scheduled
of
Number
returned
 
 vials
unused
 
of
Number 
-

Number 
Compliance 
 
 
Gross non compliance will be defined as compliance lower than 80% or greater than 120% and 
in case of non compliance the patient will be excluded from the Per Protocol Set (see § 10.1.3). 
Since this definition does not warrant that the study eye(s) treatment is compliant, if indicated 
the SAP will contain further definitions based upon the diary card information. 
10.4 
Demographic, baseline and background characteristics 
Demographic and baseline characteristics will be examined per treatment group according to 
qualitative or quantitative data. Qualitative data will be listed and summarized in contingency 
tables. Quantitative data will be listed and summarized using descriptive statistics. 
10.5 
Analysis of ophthalmological evaluations  
All efficacy variables will be summarized for all study eye(s) together using descriptive 
statistics for quantitative variables, and frequencies for qualitative variables by treatment and 
evaluation time point. Changes from baseline (Day 0 Baseline Visit assessment) will be 
presented as well, if applicable. 
No adjustment for multiplicity has been made considering that rhNGF efficacy is to be 
evaluated on the contemporaneous change of both variables (see ICH-E9). 
Additional details on the analyses will be provided in the statistical analysis plan.

Safety and tolerability evaluation 
AEs 
Adverse events (AEs) will be coded by System Organ Class (SOC) and Preferred Term (PT), 
using the Medical Dictionary for Regulatory Activities (MedDRA). 
TEAEs are all events occurring or worsening after the first dose of the IMP. 
Individual AEs/TEAEs will be listed in patient data listings. TEAEs will be summarized by 
treatment. The number and percentage of patients with any AE and the number of TEAEs will 
be tabulated by SOC and PT, seriousness, relationship to treatment and severity.

EVALUATION OF ADVERSE EVENTS AND SAFETY 
INFORMATION 
11.1 
Definition and handling of AEs and SAEs  
 
Adverse Events 
An Adverse Event (AE) is defined as any untoward medical occurrence in a patient or clinical 
trial patient administered a medicinal product, which does not necessarily have a causal 
relationship with the study treatment (Directive 2001/20/EC). An AE can therefore be any 
unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or 
disease temporally associated with the use of a medicinal (investigational) product, whether or 
not related to the medicinal (investigational) product. 
 
Adverse Drug Reaction 
An Adverse Drug Reaction (ADR) is any noxious and unintended response to an Investigational 
Medicinal Product (IMP) which is a reasonably likely to have been caused by the drug, at any 
dose administered.   
For the purposes of reporting to the concerned Authorities, “reasonable possibility” means there 
are facts (evidence) or arguments to suggest a causal relationship between the drug and the 
adverse event (reference: par. 11.4 and 11.5). 
 
Serious Adverse Event (SAE)  
A serious adverse event (SAE) is defined in line with Directive 2001/20/EC as any adverse 
experience that meets any of the following criteria: 
 
 results in death 
 is life-threatening  
(NOTE: Life-threatening means that the patient was at immediate risk of death from the 
reaction as it occurred, i.e., it does not include a reaction which hypothetically might 
have caused death had it occurred in a more severe) 
 
 requires inpatient hospitalization or prolongation of existing hospitalization 
(NOTE: In general, hospitalization means that the individual remained at the hospital 
or emergency ward for observation and/or treatment (usually involving an overnight 
stay) that would not have been appropriate in the physician's office or an out-patient 
setting. Complications that occur during hospitalization are AEs. If a complication 
prolongs hospitalization or fulfils any other serious criteria, the event is serious. When 
in doubt as to whether “hospitalization” occurred, the event should be considered 
serious 
 

 
CONFIDENTIAL 
rhNGF in Post Cataract and Refractive Surgery 
Sponsor code NGF0116 
Final Version 3.0 12 Apr 2017 
Page 42 of 59 
 results in persistent or significant disability/incapacity 
(NOTE: The term disability means a substantial disruption of a person’s ability to 
conduct normal life functions. This definition is not intended to include experiences of 
relatively minor medical significance such as uncomplicated headache, nausea, 
vomiting, diarrhoea, influenza, or accidental trauma (e.g., sprained ankle) which may 
interfere or prevent everyday life functions but do not constitute a substantial 
disruption) 
 
 results in a congenital anomaly/birth defect 
  is an important medical event 
(NOTE: An important medical event is an event that may not result in death, be life-
threatening, or require hospitalization but may be considered a SAE when, based upon 
appropriate medical judgment, it may jeopardize the patient’s well-being and may 
require medical or surgical intervention to prevent one of the outcomes listed in the 
definitions for SAEs. Examples of such medical events include allergic bronchospasm 
requiring intensive treatment in an emergency room or at home, blood dyscrasias or 
convulsions that do not result in patient hospitalization or the development of drug 
dependency or drug abuse) 
 
Pre-planned hospitalization or hospitalization for routine treatment or monitoring of the studied 
indication, not associated with any deterioration in condition are not considered to be SAEs 
(see Par. 11.5.2). These events must be recorded in the AE page of the eCRF where a variable 
will be ticked to indicate that they are not SAEs. 
If a SAE results in death, the event shall be reported as SAE and cause of death shall always be 
investigated and specified as soon as known, as applicable. 
A Non-Serious Adverse Event/Non-Serious Adverse Drug Reaction is an adverse event or 
adverse drug reaction that does not meet the criteria listed above for a serious adverse 
event/serious adverse drug reaction. 
 
Suspected serious unexpected adverse reaction 
A Suspected Serious Unexpected adverse reaction (SUSAR) is defined as an adverse reaction 
that is both unexpected (not consistent with the applicable product information) and also meets 
the definition of a Serious Adverse Reaction. 
The determination of expectedness should be made on the basis of the IB. 
11.2 
Adverse Events of Special Interest (Sight-threatening Events) 
The following adverse events are considered to be of special interest and by default shall be 
reported as SAEs (medically important criteria): 
 Adverse Events that caused a decrease in visual acuity of >30 ETDRS letters or > +0.6 
LogMAR (compared with the last assessment of visual acuity at the last visit) lasting >1 
hour 

 
CONFIDENTIAL 
rhNGF in Post Cataract and Refractive Surgery

Final Version 3.0 12 Apr 2017 
Page 43 of 59 
 Adverse Events that caused a decrease in visual acuity to the level of Light Perception or 
worse lasting >1 hour 
 Adverse Events that required surgical intervention (e.g., conventional surgery, vitreous tap 
or biopsy with intravitreal injection of anti-infectives, or laser or retinal cryopexy with gas) 
to prevent permanent loss of sight 
 Adverse Events associated with severe intraocular inflammation (i.e., 4+ anterior chamber 
cell/flare or 4+ vitritis) 
 Adverse Events that, in the opinion of the Investigator, may require medical intervention to 
prevent permanent loss of sight. 
 
11.3 
Adverse Events (AE) Monitoring 
At each post-baseline visit, after the patient has had the opportunity to spontaneously mention 
any problems, the Investigator or appropriate designee should inquire about AEs by asking the 
standard questions:  
 
 “Have you had any health problems since your last study visit?” 
 “Have there been any changes in the medicines you take since your last study visit?”  
 
AEs should be reported for any clinically relevant change in concomitant medication(s) that is 
the result of an untoward (unfavourable and unintended) change in patient's medical conditions. 
Changes in any protocol-specific ocular or systemic parameter evaluated during the study are 
to be reviewed by the Investigator. In addition, the patient’s responses to any questionnaire 
utilized during the study are to be reviewed by the Investigator. Any untoward (unfavourable 
and unintended) change in a protocol-specific parameter or questionnaire response that is 
clinically relevant is to be reported as an AE. These clinically relevant changes will be reported 
regardless of causality. 
11.4 
Recording 
Adverse Events:  
All AEs (non-serious and serious) which occur during the course of the study will be recorded 
in the eCRF. Any pre-existing medical conditions or signs/symptoms present in a patient prior 
to the start of the study (i.e., before informed consent is signed) until completion of the follow 
up period, should be specified in the eCRF. Subsequent to signing an informed consent form, 
all untoward medical occurrences that occur during the course of the study must be documented 
on the eCRF. When possible, signs and symptoms indicating a common underlying pathology 
should be documented as one comprehensive event. For each recorded event, the AE 
documentation must include the onset date, outcome, resolution date (if event is resolved), 
intensity (i.e., severity), any action with study treatment taken as a result of the event, and an 
assessment of the adverse event relationship to the study treatment.  
Relationship of AEs to the Investigational Product 
The Investigator will assess the relationship between the AE and the investigational medication, 
according to the criteria in Table below:

rhNGF in Post Cataract and Refractive Surgery 
Sponsor code NGF0116 
Final Version 3.0 12 Apr 2017 
Page 44 of 59 
Table 11.4.1 
Relationship of the Adverse Event to the Investigational Product 
None (Intercurrent 
Event) 
An event that is not and cannot be related to the investigational product, e.g. patient 
is a passenger in a road traffic accident 
Unlikely (remote) 
Relationship is not likely e.g. a clinical event including laboratory test abnormality 
with temporal relationship to drug administration which makes a causal relationship 
improbable and in which other drugs, chemicals or underlying disease provide 
plausible explanations 
Possible 
Relationship may exist, but could have been produced by the patient’s condition or 
treatment or other cause 
Probable 
Relationship is likely, the AE abates upon discontinuation of investigational product 
and cannot be due to the patient’s condition 
Highly Probable 
Strong relationship, the event abates upon discontinuation of investigational 
product and, if applicable, re-appears upon repeat exposure 
 
Severity of AEs 
The Investigator will grade the severity of any AE using the definitions in the Table below. For 
each episode, the highest severity grade attained should be reported. 
Table 11.4.2 
Intensity (Severity) of the Adverse Event 
Mild 
Grade 1 - Does not interfere with patient’s usual function (awareness of symptoms 
or signs, but easily tolerated [acceptable]). 
Moderate 
Grade 2 - Interferes to some extent with patient’s usual function (enough discomfort 
to interfere with usual activity [disturbing]). 
Severe 
Grade 3 - Interferes significantly with patient’s usual function (incapacity to work 
or to do usual activities [unacceptable]) 
 
11.5 
Serious Adverse Event Reporting 
 
Reporting Procedure for Investigators to Sponsor or CRO  
The Investigator must record all SAEs, including sight-threatening events, occurring at any time 
during the study regardless of presumed causal relationship, both in the dedicated section of 
eCRF and on a specific Non-Carbon Repeat Serious Adverse Event form (included in the 
Investigator’s Site File) within 24 hours of learning of the event. Within 24 hours from first 
knowledge of the SAE, the Investigator shall send the filled in and signed SAE form to the 
CRO and to the Sponsor at the following addresses:

If assistance is needed with the reporting of a SAE, contact details for the CRO/Sponsor are 
provided in the section “Contact Information”.  
Serious adverse events will be managed directly by the Dompé Drug Safety department, with 
CRO support for Follow Up requests. 
The Investigator should also report information on SAEs that continue after patient has 
completed his/her participation in the study (whether study completion or withdrawal), unless 
patient has withdrawn his/her consent. 
Whenever more than one SAE is observed, the Investigator should identify which is the primary 
adverse event, i.e. the most relevant one. If other events are listed in the same report, the 
Investigator, along with their relatedness to the Investigational Product, should identify which 
adverse events are serious and which are non-serious. In any case, the Investigator is requested 
to record his/her opinion about the relatedness of the observed event(s) with the investigational 
medication. 
In line with CT3 Detailed Guidance and ICH E2A provisions, although the Investigator does 
not usually need to actively monitor patients for AEs once the trial has ended, if the Investigator 
becomes aware of a SAE occurring to a patient after that patient has ended his/her participation 
in the study (whether study completion or withdrawal), the SAE should be reported by the 
Investigator to Dompé Drug Safety. Such “post-study cases” should be regarded for expedited 
reporting purposes as though they were study reports. Therefore, a causality assessment and 
determination of expectedness are needed for a decision on whether or not expedited reporting 
is required. 
Copies of all correspondence relating to reporting of any SAEs should be maintained in the 
Investigator’s Files.

Conditions that should not be reported as serious adverse events 
The conditions listed below, that may require hospitalization of a patient, are not considered to 
be SAE and shall not be reported as such, but only need to be recorded in the eCRF: 
 Hospitalizations planned before entry into the clinical study which is part of the normal 
treatment or monitoring of the studied indication and not associated with any deterioration 
in condition. 
 Hospitalization for treatments, which was elective or pre-planned, for a pre-existing 
condition that is unrelated to the indication under study and did not worsen. 
 Hospitalization for general care not associated with any deterioration in condition. 
 Treatment on an emergency, outpatient basis for an event not fulfilling any of the 
definitions of SAEs given above and not resulting in hospital admission. 
In addition, abnormal lab values or test results that do not induce clinical signs and/or symptoms 
and require intervention/therapy, i.e. are clinically significant shall not be considered SAE: 
 
Reporting Procedure to IEC and to Regulatory Authorities 
During the course of the clinical trial, Dompé shall report any serious unexpected suspected 
adverse reaction (SUSAR) to Eudravigilance Clinical Trial Module and to the concerned IEC 
which approved the protocol as soon as possible and in no event later than: 
 
(a)  seven calendar days after becoming aware of the information if the event is fatal or 
life threatening; and 
(b)  fifteen calendar days after becoming aware of the information if the event is neither 
fatal nor life threatening. 
 
Dompé shall, within eight days after having informed the IEC/Competent Authority under 
paragraph (a) and within fifteen days under paragraph (b), submit a complete report in respect 
of that information that includes an assessment of the importance and implication of any 
findings, made on the basis of follow up information provided by the Investigator. 
Dompé shall be responsible for cross trial reporting, as necessary. 
Dompé shall assess SAE report received for relationship with IMP and expectedness. 
Expectedness will be assessed with respect to the current Investigator’s Brochure: due to the 
early phase of development, all SAEs will be considered unexpected. 
For serious adverse event reported by the Investigator as not related that is subsequently revised 
to be related by the Sponsor, the Investigator will receive a notification. 
Events considered “Possible”, “Probable” and “Highly Probable” related to the IMP treatment 
will be reported to appropriate regulatory authorities. 
Treatment will be unblinded by Sponsor Pharmacovigilance prior to submission of a SUSAR 
to Regulatory Authorities and European IECs and only cases referred to active treatment will 
be expeditable for regulatory reporting, in line with law requirements.

Final Version 3.0 12 Apr 2017 
Page 47 of 59 
The Sponsor shall be responsible to prepare and submit periodical update reports as appropriate 
to Investigator and to Competent Authority and Ethics Committee. 
11.6 
Follow-up of Patients with Adverse events 
The Investigator is responsible for adequate and safe medical care of patients during the trial 
and for ensuring that appropriate medical care and relevant follow-up procedures are 
maintained after the trial. All AEs should be followed-up to determine outcome of the reaction 
or until 10 days after the final visit. The Investigator should follow-up the event until resolution 
or stabilization of the condition. It is the Investigator's responsibility to assure that the patients 
experiencing AEs receive definite treatment for any AE, if required. 
Follow-up reports (as many as required) should be completed and faxed/e-mailed following 
the same procedure above, marking the SAE form as “follow up Number XX”. 
11.7 
Pregnancy in the Clinical Trial 
Women of childbearing potential are not excluded from the study as long as adequate birth 
control methods are being utilized. Women of childbearing potential are defined as all women 
physiologically capable of becoming pregnant. Adequate birth control methods are summarized 
in the protocol’s exclusion criteria. 
Prior to enrolment in the clinical trial, female patients of childbearing potential and their 
partners must be advised of the importance of avoiding pregnancy during the entire course of 
the study treatment and for the 30 days after the study treatment period ends and of the potential 
risks associated with an unintentional pregnancy. During the trial, female patients are to be 
instructed to contact the Investigator immediately if they suspect they might be pregnant; in the 
same way, male patients who become aware that the partner might be pregnant, are to be 
instructed to contact the Investigator immediately.  
The Investigator must report every pregnancy on a pregnancy report form (included in the 
Investigator’s Site File) as soon as possible (within 24 hours of learning of the pregnancy to the 
CRO/Dompé Drug Safety contacts reported at Paragraph 11.5.1, even if no AE has occurred, 
and follow it to term. If, however, the pregnancy is associated with an SAE (eg, if the mother 
is hospitalized for dehydration), in addition to the pregnancy report form, a separate SAE report 
form must be filed as described in Section 11.5.1 with the appropriate serious criterion (eg, 
hospitalization) indicated on the SAE report form. Miscarriage, stillbirth and any 
malformation/disease must be reported as a SAE. Any pregnancy occurring to a female patient 
leads to the immediate cessation of study treatment. 
11.8 
Adverse Events Causing Treatment Discontinuation 
If a patient is withdrawn from the study as a consequence of an AE, this must be recorded and 
reasoned in the eCRF, and the patient must be followed up until the resolution of the AE or as 
instructed by the medical monitor.

11.9 
Overdose  
Cases of overdose (accidental or intentional) which result in serious adverse events are to be 
handled following emergency procedures, and reported within 24 hours from the Investigator’s 
knowledge of its occurrence. This includes reports related to drug intake through different 
routes (e.g. ingestion), or drug intake with suicidal intentions and consequent drug overdose. 
Since in the preclinical toxicology studies in animals and in the multiple ascending dose study 
performed in healthy volunteers none of the dose has caused an overdose as documented by 
adverse reaction, for the purpose of this study we define that the administration of more than 3 
times the total daily dose on any given treatment day will be reported as an overdose, even if 
not associated with adverse reactions, and shall be reported to Dompé’s clinical research 
personnel and CRO by e-mail or fax within 24 hours using the SAE form, in order to have 
information about symptoms, corrective treatment and outcome of overdose.

 DATA MANAGEMENT PROCEDURES 
12.1 
Data collection – eCRFs 
The Investigator must ensure that the clinical data required by the study protocol are carefully 
reported in the eCRFs. He must also check that the data reported in the eCRFs correspond to 
those in the patients’ source documents.  
An electronic case report form (eCRF) will be provided for each subject.  
All protocol-required information collected during the study must be entered by the 
Investigator, or designated representative, in the eCRF. Details of eCRF completion and 
correction will be explained to the Investigator. If the Investigator authorizes other persons to 
make entries in the eCRF, the names, positions, signatures, and initials of these persons must 
be supplied to the Sponsor.  
The Investigator, or designated representative, should complete the eCRF pages as soon as 
possible after information is collected, preferably on the same day that a study subject is seen 
for an examination, treatment, or any other study procedure. Any outstanding entries must be 
completed immediately after the final examination. An explanation should be given for all 
missing data. 
12.2 
Unique subject identifier 
All the patients who sign the informed consent form for the present study will be coded with 
“unique subject identifiers” when data are extracted from the study database into the domains 
of the CDISC SDTM model. The unique subject identifier for study site consists of the Sponsor 
study code (i.e. NGF0116), the 4-digit screening number (e.g. S001, S002, etc.) and, if 
applicable, the 3-digit subject study number (e.g. 001, 002, etc.).  
Study code, screening number and subject study number are separated by slashes (e.g. 
“NGF0116/S001/001”). The last 5 digits of the unique subject identifier (randomized subjects), 
corresponding to the subject screening and subject study numbers separated by a slash, or the 
last 3 digits of the unique subject identifier (not randomized subjects), corresponding to the 
subject screening number, will appear as subject identifier in the individual listings and figures 
of the clinical study report and will be used to identify the subjects in in-text tables or wording 
(if applicable). 
12.3 
Database management 
Data management of all data captured within the eCRF will be performed by the CRO with the 
OmniComm TrialMaster™ . CRO will update and verify the database and create the final SAS 
data sets. The tabulation datasets and analysis datasets created according to the standard CDISC 
(STDM and ADaM) will be provided to the Sponsor with all the other study documentation.

STUDY MONITORING, QUALITY CONTROL AND 
QUALITY ASSURANCE 
13.1 
Monitoring 
The monitoring visits will be conducted by a local monitor.  
Monitoring will comply with ICH-GCP chapter 5.18 requirements for what concerns 
monitoring purpose, selection and qualifications of monitors, extent and nature of monitoring, 
monitoring procedures, monitoring reports. 
Adequate time and availability for monitoring activities should be ensured by the Investigator 
and key study personnel. 
Data verification is required and will be done by direct comparison with source documents, 
always giving due consideration to data protection and medical confidentiality. In this respect 
the Investigator will assure support to the monitor at all times. 
The Investigator agrees, by written consent to this protocol, to fully co-operate with compliance 
checks by allowing authorised individuals to have access to all the study documentation. In 
addition to the monitoring activities performed by the study monitor, the Sponsor could perform 
some quality control activities to verify the compliance with the study procedures and the ICH-
GCP guidelines.  
13.2 
Quality Control and Quality Assurance  
The CRO has implemented and maintains a Quality System that includes quality controls and 
audits at different study steps with written SOPs to ensure that the study is conducted in 
compliance with the protocol and all effective amendments, ICH-GCP, and the applicable 
regulatory requirement(s) and that data have been reliably and correctly generated, recorded, 
processed and reported, in agreement with the ALCOA principles (Attributable-Legible-
Contemporaneous-Original-Accurate). 
13.3 
Applicable SOPs 
The Sponsor, the clinical centre and the CRO will follow their respective SOPs in the conduct 
of the respective activities, unless otherwise stated in written agreements. SOPs will be made 
available for review, if required. 
13.4 
Data access 
The Investigator and the CRO will ensure that all raw data records, medical records, eCRFs and 
all other documentation that is relevant to this study will be made accessible to monitoring 
activities, audits, IEC review, and regulatory inspection.

 ETHICAL CONSIDERATIONS 
14.1 
Ethics and Good Clinical Practice (GCP) 
The study will be performed in accordance with the relevant guidelines of the Declaration of 
Helsinki. 
The approval of the study protocol by the relevant Local Research Ethics Committees 
Authorities will be obtained before the start of the study. 
Study notification to the Competent Authorities will be performed according to the Italian 
current regulations. 
The present clinical study will be carried out according to the general principles of “ICH Topic 
E6, CPMP/ICH/135/95”, July 1996 including post Step 4 errata, status September 1997 and 
post Step errata (linguistic corrections), July 2002. 
14.2 
Informed consent 
Before being enrolled into the clinical study, the patients must have expressed their consent to 
participate, after the Investigator has explained to them, clearly and in details, the scope, the 
procedures and the possible consequences of the clinical study. Information will be given in 
both oral and written form. The information sheet and informed consent form will be prepared 
in the local language by the CRO and must be approved by the EC and regulatory authorities. 
It will include all the elements required by law according to the ICH-GCP recommendations.  
In addition to the standard requirements that physicians are currently obliged to observe when 
providing information, the following points must also be covered: 
 a description of the aims of the study and how it will be organised 
 the type of treatment 
 any potential negative effects attributable to the study treatment 
 the freedom to ask for further information at any time 
 the patients’ right to withdraw from the clinical study at any time without giving reasons 
and without jeopardising their further course of medical treatment  
 the existence of patient insurance cover and obligations following from this cover 
Adequate time and opportunity to satisfy questions will be given to the patients and the time 
will be recorded. 
The Investigator will be supplied with an adequate number of blank informed consent forms to 
be used. The forms will be signed and dated by both the Investigator and the patients.  
A copy of the signed form will be given to the patient. 
To ensure medical confidentiality and data protection, the signed informed consent forms will

remained within a clinically acceptable range (i.e. not clinically significant changes 
compared to baseline) 
 arrange for alternative medical care of the withdrawn patient, if necessary 
 report in the eCRF date and time of the last dose administration, and date and primary reason 
of study discontinuation 
 record in the eCRF any follow-up, if the patient is withdrawn for an AE 
 
Replacement 
Discontinued patients will not be replaced. 
14.5 
Study termination 
The study will be considered terminated at the date of the last visit of the last patient or upon 
completion of any follow-up procedure described in the protocol. The Investigator and the 
Sponsor have the right to discontinue the study at any time for reasonable medical and/or 
administrative reasons. As far as possible, this should occur after mutual consultation. Reasons 
for discontinuation have to be documented appropriately. In this event, no further patients will 
receive doses of the study drugs, and patients already having received a dose of study drug will 
not receive any further doses of the study IMP but will undergo all safety assessments scheduled 
after the last dose of study drug, up to an including the end of study examination.

 ADMINISTRATIVE PROCEDURES 
15.1 
Protocol amendments 
In order to obtain interpretable results, neither the Investigator nor the Sponsor will alter the 
study conditions agreed upon and set out in this protocol. Amendments should be made by 
mutual agreement between the Investigator and the Sponsor. Any amendment must be set out 
in writing, giving the reasons, and being signed by all concerned parties. The amendment 
becomes then part of the protocol. 
All amendments will be sent to the EC and concerned Competent Authorities. 
15.2 
Study documentation and record keeping 
The Investigator should ensure the accuracy, completeness, legibility, and timeliness of the data 
reported in the eCRFs and in all required reports. 
The Investigator must keep source documents for each patient in the study. All information on 
the eCRFs must be traceable to these source documents, which are generally stored in the 
patient's medical file. The source documents should contain all demographic and medical 
information, including ophthalmic assessments, etc., and the original signed informed consent 
forms. 
Data reported on the eCRF, that are derived from source documents, should be consistent with 
the source documents or the discrepancies should be explained. 
The Investigator and the Sponsor should maintain the study documents as specified in the 
“Essential Documents for the Conduct of a Clinical Trial” chapter 8 of ICH-GCP and as 
required by the applicable regulatory requirement(s).  
These are documents which individually and collectively permit evaluation of a study and the 
quality of the data produced and include groups of documents, generated before the study 
commences, during the clinical study, and after termination of the study and include but are not 
limited to, study protocol, amendments, submission and approval of EC, raw data of patients 
including ophthalmic assessments, insurance contracts, certificate of analysis of the IMP(s), 
drug accountability records, signed informed consent forms, confidential subjects identification 
code, eCRFs, curricula vitae of the Investigator and other participants in the study, study staff 
lists and responsibilities, monitoring reports and final study report. 
The Investigator and the Sponsor should take measures to prevent accidental or premature 
destruction of these documents. 
Study documents must be retained by the Investigator and the Sponsor as long as needed to 
comply with ICH-GCP, national and international regulations. By signing the protocol, the 
Investigator and the Sponsor agree to adhere to these requirements. 
15.3 
Confidentiality and data protection 
By signing this protocol, the Investigator and the CRO agree to keep all the information 
provided by the Sponsor in strict confidentiality and to request similar confidentiality from 

 
CONFIDENTIAL 
rhNGF in Post Cataract and Refractive Surgery

Final Version 3.0 12 Apr 2017 
Page 57 of 59 
his/her staff. Study documents provided by the Sponsor (protocols, IB, eCRFs and other 
materials) will be stored appropriately to ensure confidentiality. The information provided by 
the Sponsor to the Investigator and to the CRO cannot be disclosed to others without direct 
written authorisation from the Sponsor, except for the extent necessary to obtain the informed 
consent from the patients wishing to participate in the study. 
Data on patients collected on the eCRFs during the study will be documented in an anonymous 
way (see § 12.2). If, as an exception, it becomes necessary to identify a patient for safety or 
regulatory reasons, the monitor, the Sponsor and the Investigator will be bound to keep this 
information confidential. 
15.4 
Publication policy 
The Sponsor agrees that the study results (including negative and inconclusive as well as 
positive results) can be made publicly available by the Investigator publishing in peer reviewed 
journals; presenting results at scientific congresses; and posting information and results on 
internet-based public registers and databases. 
In any case, study results will be communicated in full to the competent Health Authorities by 
the submission of a complete Clinical Study Report. 
As the Sponsor agrees that the study results can be published by the Investigator(s), the 
Investigator agrees to submit any manuscript (abstract, publication, paper etc.) to the Sponsor 
before any public disclosure. 
This will be done in order to ensure that clinical trial results are reported in an objective, 
accurate and balanced manner. The Sponsor reviews proposed manuscripts prior to submission 
within a reasonable period of time (30-90 business days in relation with the complexity of the 
work). 
The Investigator(s) will also be provided by the Sponsor with the clinical study report and the 
results of any additional analysis, tables, figures etc. undertaken for the purposes of the article, 
in order to take responsibility for the content of the publication(s). 
On an exceptional basis, the Sponsor may temporarily delay registration of certain data 
elements (e.g. compound, name, outcome, measures etc.) to seek necessary intellectual property 
protection. This is because early disclosure of such a data could, in some circumstances, prevent 
or negatively impact patentability 
15.5 
Liability Statement  
On behalf of the Sponsor, the investigational sites will take out reasonable third-party liability 
insurance cover in accordance with all local legal requirements. The civil liability of the 
Investigators, the persons instructed by them and the hospital, practice or institute in which they 
are employed and the liability of the Sponsor in respect of financial loss due to personal injury 
and other damage which may arise as a result of the carrying out of this study are governed by 
the applicable local laws. 
As a precautionary measure, the Investigators, the persons instructed by them and the hospital, 
practice or institute are included in such cover in respect of work done by them in carrying out

this study to the extent that the claims are not covered by their own professional indemnity 
insurance. 
15.6 
Financing of the Study 
The financial aspects of this study are described in detail in the contract between Sponsor and 
CRO and between CRO and clinical site involved in this study.  
15.7 
Responsibilities of the Investigator 
The Investigator is aware of his/her responsibility towards the Sponsor for all the actions 
delegated by him/her to other members of his/her staff assigned to the conduct of the study. 
Except where specifically required, the wording "Investigator" used in this protocol and in the 
eCRF, refers to the Investigator or the qualified person designated by him/her, who may carry 
out activities relevant to the clinical trial and sign the study documents on his/her behalf. 
The Investigator is obliged to conduct the study in compliance with the study protocol and in 
adherence to GCP (ICH E6) and with the principles of the Declaration of Helsinki (1964) and 
subsequent revisions as well as in respect of applicable legislation. 
15.8 
Final study report 
The final Clinical Study Report will be written by the CRO and then approved by Dompé 
farmaceutici S.p.A. and the Principal Investigator. It will be written in compliance with the ICH 
E3 guideline for both content and format.
