Conditions: Dry Eye Syndrome
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 261
Healthy volunteers: no

Brief summary:
The objective of this study is to assess the efficacy and safety of rhNGF eye drops at 20 μg/ml concentration administered two or three times daily for 4 weeks in patients with moderate to severe dry eye.

Detailed description:
This is a 4 weeks, Phase II, multicenter, randomized, double-masked, vehicle-controlled, parallel group study with 12 weeks of follow-up, designed to perform dose-ranging and to evaluate safety and efficacy of recombinant human Nerve Growth Factor (rhNGF) eye drops solution versus vehicle, in patients with moderate to severe dry eye (DE).

Test product is rhNGF 20 μg/ml; reference product is vehicle. Test and reference will be instilled in both eyes according to the following scheme:

Group 1: one drop of rhNGF 20 μg/ml is instilled in both eyes three times daily (every 6-8 hours, e.g. 7:00 am, 02:00 pm; 09:00 pm).

Group 2: one drop of rhNGF 20 μg/ml is instilled in both eyes two times daily (in the morning and in the evening) plus one drop (40 μL) of vehicle (placebo) is instilled in both eyes once daily in the afternoon.

Group 3: one drop (40 μL) of vehicle (placebo) is instilled in both eyes three times daily (every 6-8 hours, e.g. 7:00 am, 02:00 pm; 09:00 pm).

Approximate randomization 1:1:1 of 261 patients to rhNGF eye drops solution 20 μg/ml TID (87 patients) or rhNGF eye drops solution 20 μg/ml BID + vehicle eye drop SID (86 patients) or vehicle eye drops solution (88 patients) TID for 4 weeks was applied.

Arms:
arm 1: One drop of rhNGF 20 μg/ml will be instilled in both eyes three times daily (every 6-8 hours) arm 2: One drop of rhNGF 20 μg/ml will be instilled in both eyes two times daily (BID) plus one drop (40 μL) of vehicle will be instilled in both eyes once daily (OD) (every 6-8 hours) arm 3: Vehicle eye one drop will be instilled in both eyes three times daily (every 6-8 hours)

Interventions: intervention 1: rhNGF 20 μg/ml intervention 2: rhNGF 20 μg/ml + vehicle intervention 3: Vehicle
Intervention descriptions: intervention 1: one drop of rhNGF 20 μg/ml will be instilled in both eyes three times daily (every 6-8 hours) intervention 2: one drop of rhNGF 20 μg/ml will be instilled in both eyes two times daily plus one drop (40 μL) of vehicle will be instilled in both eyes once daily (every 6-8 hours).

rhNGF will be instilled in the morning and in the evening while the vehicle will be instilled in the afternoon. intervention 3: one drop of vehicle will be instilled in both eyes three times daily (every 6-8 hours)

The second paragraph has been modified as follows:“1) Statistical 
Methods - Efficacy analysis  
Primary endpoints will be analyzed using analysis of variance including 
only the treatment as main factor followed by pre-planned comparisons 
from Vehicle and rhNGF dosages according to Williams procedure. In 
addition, the  primary endpoint will be summarized using descriptive 
statistics for continuous variables by treatment and visit. The change 
from baseline value will also be summarized for all post-baseline 
visits.  
An explorative sensitivity analyses of primary endpoint will be 
conducted including in the analysis of variance the absence/presence 
of diagnosis of Primary Sjögren's Syndrome and its interaction with 
treatments as covariates. If the interaction term is statistically 
significant (at the 0.10 level given its explorative nature), the 
treatment effects within patients with and without Primary Sjögren's 
Syndrome will be provided.” 
The following paragraph has been added as third paragraph  
“Secondary endpoints will be presented with the appropriate 
descriptive statistics and inferential statistics appropriate for the 
nature of variable analyzed will be done in order to test treatment 
effect.”

treatment and will be evaluated at the end of the safety follow-up period. 
During the safety follow-up period patients will not use further treatment 
except preservative free artificial tears provided by the Sponsor three 
times daily (morning, afternoon, evening ).” 
Section: 3.3 figure 1 has been modified to specify a time window for the 
wash-out period. 
 
Section: 4:  The following paragraphs will be added:  
“The safety and efficacy of rhNGF eye drops will be investigated also 
in a specific subgroup of patients with hyposecretive dry eye, i.e., 
patients with dry eye due to primary Sjögren's syndrome (2, 14). To 
gain information on the safety and efficacy of rhNGF in this subgroup 
of patients at least sixty (60) patients with a documented diagnosis of 
Primary Sjögren's Syndrome are out of 300 total patients are needed. 
It should be noted that patients with this type of dry eye could have 
already been enrolled based on the inclusion/exclusion criteria of the 
previous version of the study protocol. This amendment is applied 
only to set a minimum prespecified number of patients with Primary 
Sjögren's Syndrome.  The nature of the resulting statistical analysis 
in this subgroup of patients will be explorative. 
Including at least y 60 subjects with documented diagnosis of Primary 
Sjögren's Syndrome within the total sample size (20%) will have no 
impact on the initial assumptioms concerning sample size for the 
following reasons: 
x 
The previous study (NGF0216), on which sample size 
assumptions have been based (see section 9.1), reports a 
similar prevalence of patients with Primary Sjögren's 
Syndrome in their medical history (⁓25% in the FAS 
population). 
x 
As dry eye due to Sjogren’s syndrome is a hyposecretive form 
of the disease, the primary endpoint is appropriate for both 
the whole study population and the subgroup with Sjögren's 
syndrome”

The following section has been added as section “4.3: ELIGIBLE EYE  
Process for determining the eligible eye: assuming that all the 
inclusion/exclusion criteria are met in both eyes, the worse eye 
(eligible eye) will be determined at the baseline visit using a 
stepladder approach, as follows: 
1. Schirmer’s Test (since this is the primary endpoint)-Worse eye 
determined as eye with lower Schirmer I score. If 
Schirmer I score is the same in both eyes, worse eye will 
be determined by NEI score (cornea+conjunctival 
staining). 
2. NEI score (cornea+conjunctival staining).  
If all of the above are identical, determination of the worse eye will 
be based on the Investigator’s judgement, then simply use the right 
eye as the eligible eye.”

“The inclusion of approximately 60 subjects with documented 
diagnosis of Primary Sjögren's Syndrome within the planned 300 
patients will have no impact on the initial study assumptions 
(Standard Deviation of 10.78 and DELTA of 5.3 mm) because the 
patients could have been enrolled based on the previous criteria on 
which sample size was based. Moreover, a similar prevalence of 
patients with Primary Sjögren's Syndrome has already been reported 
in the NGF0216 medical history (⁓25% of patient the FAS 
population).” 
Section 9.2. The first paragraph has been modified as follows:  
“The Screened Population will consist of all patients with the 
signature of the informed consent, the assignment of a PID number 
and regardless the completion of all the screening procedures.”  
The second  paragraph has been modified as follows: “The Eligible 
Population will consist of all patients with all inclusion/exclusion 
criteria met. Otherwise the patientspatient will be defined as 
screening failure.”

analysis set will be used for demographic, baseline and background 
characteristics.” 
The second paragraph has been modified as follows:Safety Population -
The Safety Population (SAF) will consist of all randomized patients 
who took at least one dose of IP. This analysis set will be used for the 
safety analysis. Patients will be analyzed according to the treatment 
received.” 
The third paragraphhas been modified has follows:  
“Full Analysis Set - Full Analysis Set (FAS) will consist of all 
randomized patients who took at least one dose of IP and who have at 
least one post-baseline efficacy measurement for the primary

“Per Protocol Set - “Per Protocol Set (PP) will consist of all patients 
in the FAS who fulfil the study protocol requirements in terms of 
investigational medicinal product intake and collection of primary 
efficacy data and with no major deviations that may affect study 
results. This analysis set will be used for supportive efficacy analysis. 
Patients will be analyzed according to the treatment received. 
Each patient will be coded by the Syneos Health statistician as valid 
or not valid for the Enrolled Set, SAF, FAS and PP.” 
Section 9.4.3.:The third bullet point has been modified as follows: 
“major 
deviation

violations).” 
Section 9.4.4.: The paragraph has been modified as follows:  
 “Demographic and baseline characteristics will be descriptively 
summarized per treatment group according to their nature.”  
Section 9.5.: The  paragraph has been modified as follows::  
“Primary endpoint will be analyzed using analysis of variance 
including only the treatment as main factor followed by pre-planned 
comparisons from Vehicle and rhNGF dosages according to Williams 
procedure.In addition, primary endpoint will be summarized using 
descriptive statistics for continuous variables by treatment and visit. 
The change from baseline value will also be summarized for all post-
baseline visits. 
An explorative sensitivity analysis of primary endpoint will be 
conducted including in the analysis of variance the absence/presence 
of diagnosis of Primary Sjögren's Syndrome and its interaction with 
treatments as covariates. If the interaction term is statistically 
significant (at the 0.10 level given its explorative nature), the 
treatment effects within patients with and without Primary Sjögren's 
Syndrome will be provided. 
Secondary endpoints will be presented by means of appropriate 
descriptive statistics.  
Changes from baseline in global SANDE score, Schirmer test II, NEI 
scales, TFBUT,  IDEEL, PGIC and EQ-5D-3L scores 4 will be 
analyzed in a similar manner as the Change from baseline in 
Schirmer test I (primary endpoint) in order to test treatment effect. 
Difference between treatment groupsgroup (Each active dose vs 
Placebo), in the percentage of patients who experienced a worsening 
in SANDE scores and/or NEI score will be tested using a chi-square 
test.  
Explorative endpoints will be summarized by means of appropriate 
descriptive statistics. Any statistical testing will be descriptive in 
nature.

CLINICAL STUDY SYNOPSIS:  
Study Number  
NGF0118 
Title of Study  
A 4 weeks, Phase II, multicenter, randomized, double-
masked, vehicle-controlled, parallel group study with 12 
weeks of follow-up to evaluate safety and efficacy of 
recombinant human Nerve Growth Factor (rhNGF) eye drops 
solution versus vehicle, in patients with moderate to severe 
dry eye (DE). 
IND N° 
115892 
Study Centers (Country)  
8-12 study sites in US 
Development Phase  
Phase II 
Objective  
The primary objective of this study is to assess the efficacy 
and safety of rhNGF eye drops at 20 µg/ml concentration 
administered two or three times daily for 4 weeks in patients 
with moderate to severe dry eye. The trial is designed to 
perform dose ranging. 
Study Design and 
Methodology  
This is a phase II,  multicenter, randomized, double masked, 
parallel arm, vehicle-controlled trial.

Safety Endpoint 
1. Incidence and frequency of Treatment-emergent 
adverse events (TEAEs), assessed throughout the 
study. 
Statistical Methods 
The data collected in this study will be summarized using 
number of observations, mean, standard deviation (SD), 
median, minimum, and maximum values for quantitative 
variables, and frequencies for qualitative variables. 
 
1) Efficacy analysis 
Primary endpoints will be analyzed using analysis of 
variance including only the treatment as main factor followed 
by pre-planned comparisons from Vehicle and rhNGF 
dosages according to Williams procedure. In addition, 
primary endpoint will be summarized using descriptive 
statistics for continuous variables by treatment and visit. The 
change from baseline value will also be summarized for all 
post-baseline visits. 
An explorative sensitivity analysis of primary endpoint will 
be conducted including in the analysis of variance the 
absence/presence of diagnosis of Primary Sjögren's 
Syndrome and its interaction with treatments as covariates. If 
the interaction term is statistically significant (at the 0.10 
level given its explorative nature), the treatment effects 
within patients with and without Primary Sjögren's Syndrome 
will be provided. 
It will be summarized using descriptive statistics for 
continuous variables by treatment and visit. The change from 
baseline value will also be summarized for all post-baseline 
visits. 
Secondary endpoints will be presented with the appropriate 
descriptive statistics and inferential statistics appropriate for 
the nature of variable analyzed will be done in order to test 
treatment effect.   
 
Explorative endpoints will be summarized by means of 
appropriate descriptive statistics. Any statistical testing will 
be descriptive in nature.

2.1. 
BACKGROUND INFORMATION 
2.1.1. 
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: high-affinity tropomyosin receptor kinase A (TrkA), a 
transmembrane tyrosine kinase, and low-affinity NGF receptor (LNGFR), also known as p75 
neurotrophin receptor (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 humor. 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.  
 
2.1.2. 
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 (E. coli) has been 
developed. However, because the biological activity of NGF relies on the formation of three 
disulfide bonds, and because disulfide 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 proNGF. After expression of proNGF in E. coli, the insoluble protein is 
isolated in the form of insoluble inactive aggregates (inclusion bodies), solubilized in a strong 
denaturing agent and subsequently converted into the natural conformation, which is determined by 
the disulfide bridges present in the natural NGF. Biologically active rhNGF is finally obtained by 
splitting off the prosequence by enzymatic cleavage. The deoxyribonucleic acid (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 rhNGF preparation during the process with the mature protein starting 
with serine 105.  
2.1.3. 
Rationale for rhNGF therapy in patients with dry eye 
 
Dry eye is a chronic inflammatory condition of the ocular surface with severe symptoms and visual 
impairment, leading to worse efficiency to perform duties for an average of 184 work days and 
resulting in an average loss of productivity estimated in 5,000USD per year per patient (1).  
Dry eye results from systemic diseases (Sjögren's syndrome, rheumatoid arthritis, systemic lupus 
erythematosus, Stevens-Johnson syndrome, thyroid disease, Bell's palsy), ocular conditions 
(Meibomian gland dysfunction, blepharitis, ocular rosacea, corneal dystrophies), elective surgeries 
(refractive surgery, blepharoplasty), eyelid conditions (lagophthalmos, entropion/ectropion), cranial 
surgeries, side effects of drugs (antihistamines, diuretics, beta-blockers), ocular injuries and burns, 
chemotherapy and radiation, aging, menopause, etc. (2).  
Dry eye pathogenesis is multifactorial; however, a number of common mechanisms can be identified: 
(i) chronic inflammation of the conjunctiva; (ii) decrease of ocular surface sensitivity; (iii) impairment 
of quantity of tears and/or quality of the tear film, including tear film hyperosmolarity; (iv) changes 
of conjunctival epithelium with squamous metaplasia and decrease of goblet cells density; (v) corneal 
epithelium damage.  
Until now, treatment has been limited to the use of artificial tears to temporarily improve lubrication 
of the ocular surface, or the use of steroids to decrease the inflammatory reaction. However, chronic 
use of steroids is associated with severe complications such as cataract and glaucoma (2). 
Cyclosporine eye drop therapy for dry eye patients has been approved in the United States but not in 
Europe. This drug seems to affect only inflammation and tear film production, without any effect on 
ocular surface sensitivity or the corneal epithelium. On the other hand, experimental and clinical 
evidence suggests that NGF may affect all the pathogenic mechanisms of dry eye, potentially 
restoring ocular surface homeostasis (3). 
Indeed, several studies have shown that NGF is involved in the regulation of tear film production. In 
fact, NGF, TrkA and p75, as well as other neurotrophins (NTs) and related receptors, are expressed 
by the rat lacrimal gland tissue; moreover, NGF has been quantified in human tears, indicating that 
NGF is basally released by the lacrimal gland (4,5,6). These data suggest that NGF may play a role 
in the maintenance of the tear film and in its alterations in drying ocular surface diseases. Specifically, 
considering that NGF potentially affects all the components of the ocular surface (cornea, 
conjunctiva, lacrimal gland, and sensory innervation), it might play an important role during dry eye 
disease. In line with this hypothesis: 1) NGF eye drop administration in a dog experimental model of 
dry eye increases tear production, conjunctival goblet cell density and corneal transparency (7, 2), an 
increased tear concentration of NGF has been reported in patients affected by keratoconjuctivita sicca

proliferation (10). 
 
2.2. 
A SUMMARY OF CLINICAL DATA  
rhNGF has been already studied in healthy volunteers and in different subject populations.  
In the completed Phase I study in healthy volunteers (study NGF0112), a total of 58 subjects (out of 
74 enrolled) were treated with single and multiple dose of different concentrations of rhNGF eye 
drops showing a good safety profile.  
Furthermore, a Phase I/II multicenter, 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 of 
Neurotrophic Keratitis NK (study NGF0212) was completed in 2015 demonstrating that rhNGF was 
very well tolerated and effective in patients with NK. A successful confirmatory study (NGF0214) 
was completed in 2016 and marketing authorization for rhNGF 20 μg/mL eye drops has been granted 
by EMA in July 2017 for treatment of moderate to severe NK. 
In addition to NK, rhNGF eye drops have been evaluated in a Phase I/II study in retinitis pigmentosa 
(RP) patients at the doses of 60 and 180 μg/mL (NGF0113), and in a phase I/II study in glaucoma at 
the dose of 60μg/mL (NGF0314). An open arm, 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 severe dry eye disease as compared to 
baseline (NGF0213). These results prompted to the conduction of two additional phase II RCTs in 
patients with dry eye disease (NGF0216) and in patients with ocular discomfort symptoms following 
refractive surgery (NGF0116) which confirmed the favourable tolerability profile of rhNGF eye drops 
at a concentration of 20 μg/mL up to 6 times daily for 8 weeks.  
In the double-masked vehicle-controlled Phase II study NGF0216 no major differences were 
observed in term of efficacy when comparing the two regimens (6 vs. 2 times/day) and treatment 
durations (8 vs. 4 weeks) in a subset of patients with similar characteristics (hyposecretive dry eye 
with Schirmer test <10mm/5min).  
The results of these two studies in dry eye disease patients, as well as the results on reflex tear 
secretion obtained in the neurotrophic keratitis trials NGF0212 and NGF0214, suggest that the rhNGF 
may be a safe and effective treatment for patients with hyposecretive dry eye disease. 
In all studies rhNGF was well tolerated and the reported ocular AEs were generally transient and 
mostly mild and moderate in intensity during the controlled treatment period and the follow-up 
period. 
Only moderate and transient ocular AEs possibly related to rhNGF administration were reported. 
In the  Phase I study in healthy volunteers of Japanese ethnicity (study NGF0117) a total of 30 subjects 
were enrolled. 20 subjects were treated with  single dose of rhNGF (formulation containing L-
methionine as excipient) at concentration 20 μg/mL and a total of 10 subjects were treated with 
placebo. During the studyno adverse events  occurred.   Single and multiple doses of rhNGF delivered

topically as eye drops were safe and well tolerated by healthy subjects of Japanese ethnicity. No 
clinically important changes in ECG were observed after dosing with rhNGF. There was no apparent 
relationship between treatment and plasma rhNGF levels, and this study did not give any indication 
for an immunogenic potential of rhNGF in humans after ophthalmic treatment. 
2.3. 
STUDY RATIONALE 
The data reported above, together with the evidence of rhNGF eye drop effectiveness in the treatment 
of patients affected by corneal epithelial defects and ulcers, make rhNGF a strong candidate for the 
treatment of dry eye disease (11, 12, 13). 
As part of the development plan, the present study was designed in order to evaluate the efficacy and 
safety of rhNGF eye drops 20 µg/mL in patients with moderate to severe dry eye. 
For additional information regarding the development of rhNGF, please consult the current IB. 
2.3.1. 
Risk assessment/benefit evaluation 
The study is considered a low risk interventional trial. It is conducted with a dose of medicinal product 
already tested and already authorized in some European countries and recently by FDA for NK 
treatment.  
The study is conducted in severe to moderate dry eye, a disease not approved, however 2 preliminary 
clinical studies were already conducted in patients with dry eye demonstrating that rhNGF is very 
well tolerated in this condition. 
The risk of this study is  comparable to the risk of the standard of care, in fact the dose proposed in 
this protocol is rhNGF 20 µg/mL three drops per day (both eyes), which is well below the dose 
approved for the treatment of NK (rhNGF 20 µg/mL six drops/eye per day). 
Considering what is discussed above no particular safety risks are foreseen with respect to the safety 
profile of the marketed product (OXERVATE® 20 µg/mL). 
 
The patients with dry eye participating in this study may potentially benefit from the application of 
rhNGF for 28 days.  
 
The following potential study risks were evaluated: 
 
1) Participant well-being e.g.- risk-benefit balance - burden of study visits  
2) Lifestyle requirements- Study specific procedures which carry risk -additional to 
standard care (es: week of run in) 
3) Complexity of study procedures  
4) Education, training, experience and resources of all investigator site staff in GCP and 
study procedures

3. OVERALL STUDY DESIGN AND INVESTIGATIONAL PLAN  
3.1. 
STUDY OBJECTIVES  
The study objective is to assess the efficacy and safety of rhNGF when administered as eye drops to 
patients with moderate to severe dry eye and to exploratively evaluate the preliminary efficacy data 
also in a group of  dry eye patients with diagnosis of Primary Sjögren's Syndrome(14). 
3.2. 
STUDY ADMINISTRATIVE STRUCTURE 
This study will be performed at 8-12 study centers located in the USA. At each study center, the 
Principal Investigator (PI) will be responsible for ensuring that the investigation is conducted 
according to the signed Investigator agreement, the protocol, GCP guidelines, and local regulations.  
The PI at each study center will be responsible for the management of the study, which will consist 
of maintaining the study file and the patient records, corresponding with the IRB, and completing 
the case report forms (eCRFs) and reporting SAEs within 24 hours of initial awareness.  
The PI is responsible for supervising any individual or party to whom the investigator delegates trial 
related duties and functions conducted at the trial site. 
If the investigator/institution retains the services of any individual or party to perform trial-related 
duties and functions, the investigator/institution should ensure this individual or party is qualified to 
perform those trial-related duties and functions and should implement procedures to ensure the 
integrity of the trial-related duties and functions performed and any data generated. 
3.3. 
OVERALL STUDY DESIGN  
 
This is a phase II, multicenter, randomized, double masked, vehicle controlled, parallel group study 
designed to perform dose ranging and evaluate efficacy of rhNGF eye drops at 20 µg/mL concentration 
administered two or three times daily for 4 weeks in patients with moderate to severe dry eye. 
Patients will be evaluated at screening visit (day -8), baseline (day 1+2), week 2 (day 14±2), week 4 
(day 28±2) or early withdrawal and week 8 (day 56±2), week 12 (day 84±4), week 16 (day 112±7) of 
follow up. 
During the screening (day -8) all procedures for inclusion will be performed. From the day of 
screening the patients will stop any kind of further treatment, except commercially available 
preservative free artificial tears for a period of 7 days and 9 days as maximum (day -8 to day -1+2) 
until the baseline visit (day 1). At the end of the wash out period (day -8 to day -1+2) , patients 
meeting the entry criteria for this study will be randomized 1:1:1 and treated for 4 weeks with either 
rhNGF eye drops 20 µg/mL TID, rhNGF eye drops 20 µg/mL BID and vehicle SID or vehicle TID.

During the 4 weeks of masked treatment only the administration of IMP it is allowed. Nevertheless, 
if strictly needed, the patient can take  preservative free artificial tears (provided by the Sponsor). The 
use (n° drops/day) of preservative free artificial tears will be clearly documented in a patient’s diary 
and in the eCRF.  
 
Following the completion of the double-blind treatment patients will be followed up for safety 
assessments for an additional 12 weeks post treatment and will be evaluated at the end of the safety 
follow-up period. During the safety follow-up period patients will not use further treatment except 
preservative free artificial tears provided by the Sponsor three times daily (morning, afternoon, 
evening ).  
The use of preservative free artificial tears will be clearly documented in a patient’s diary and in the 
eCRF. 
The total duration of the study is 17 weeks.

3.3.1. 
Rationale for Selection of dose, control group and treatment schedule in the study 
 
The dose proposed in this study (rhNGF 20 µg /mL) has already been tested both in heathy volunteers 
for five consecutive days (NGF0112 and NGF0117) and in patients affected by several ocular surface 
diseases, including dry eye. 
rhNGF 20 µg /mL (one drop in each eye six times daily for 8 weeks), was also tested in the Phase I/II 
of the NK studies (NGF0212 and NGF0214), dry eye (NGF0216) and in patients after cataract and 
refractive surgery (NGF0116). 
rhNGF 20 µg/mL administered two times daily, demonstrated to be safe and well tolerated 
(NGF0213)  will also ensure the lubrification of the ocular surface in the present study where the use 
of artificial tears will be not allowed during the treatment period.  
Higher doses of rhNGF (up to 180 µg /mL) were administrated to patients with diseases of the back 
of the eye, such as retinitis pigmentosa (Study NGF0213) for up to 168 days. 
 
The 20 μg/ml concentration of rhNGF is well sustained by the current manufacturing process and is 
the lowest used in a commercial formulation.  
A dose regimen of 2 or 3 drops per day of rhNGF eye drops and a treatment duration of 4 weeks have 
been selected based on the results of the previous clinical trials described above. 
The administration of a total of 3 drops per day for all the study arms has been chosen to guarantee 
to patients randomized to the vehicle arm to have the minimum amount of lubrication that is 
compatible with symptoms’ relief. A double-blind study design was adopted to minimize systematic 
bias. Randomization is expected to minimize patient selection bias and increase baseline 
comparability between treatment groups. The use of placebo control is critical to the study design for, 
providing an accurate estimate of the additive benefit of pharmacotherapy.   
The use of the drug’s vehicle as placebo helps in making the latter as indistinguishable from the 
rhNGF solution. 
Patients with insufficient therapeutic response, tolerability issues, or worsening of symptoms may be discontinued at 
any time during the study.

4. SELECTION OF STUDY POPULATION 
 
Male and female ≥ 18 years with moderate to severe dry eye will be included. A total of 300 patients 
will be enrolled.  
The safety and efficacy of rhNGF eye drops will be investigated also in a specific subgroup of patients 
with hyposecretive dry eye, i.e., patients with dry eye due to primary Sjögren's syndrome (2, 14). To 
gain information on the safety and efficacy of rhNGF in this subgroup of patients at least sixty (60) 
patients with a documented diagnosis of Primary Sjögren's Syndrome are out of 300 total patients are 
needed. It should be noted that patients with this type of dry eye could have already been enrolled 
based on the inclusion/exclusion criteria of the previous version of the study protocol. This 
amendment is applied only to set a minimum prespecified number of patients with Primary Sjögren's 
Syndrome.  The nature of the resulting statistical analysis in this subgroup of patients will be 
explorative. 
Including at least y 60 subjects with documented diagnosis of Primary Sjögren's Syndrome within the 
total sample size (20%) will have no impact on the initial assumptioms concerning sample size for 
the following reasons: 
x The previous study (NGF0216), on which sample size assumptions have been based (see 
section 9.1), reports a similar prevalence of patients with Primary Sjögren's Syndrome in their 
medical history (⁓25% in the FAS population). 
x As dry eye due to Sjogren’s syndrome is a hyposecretive form of the disease, the primary 
endpoint is appropriate for both the whole study population and the subgroup with Sjögren's 
syndrome.  
x As anticipated, the same patients could have already been enrolled based on the previously 
applied and approved inclusion/exclusion criteria.

ELIGIBLE EYE 
Assuming that all the inclusion/exclusion criteria are met in both eyes, the worse eye (eligible eye) 
will be determined at the baseline visit using a stepladder approach, as follows: 
1. 
Schirmer’s Test (since this is the primary endpoint)-Worse eye determined as eye with 
lower Schirmer I score. If Schirmer I score is the same in both eyes, worse eye will be 
determined by NEI score (cornea+conjunctival staining). 
2. 
NEI score (cornea+conjunctival staining).  
If all of the above are identical, determination of the worse eye will be based on the Investigator’s 
judgement, then simply use the right eye as the eligible eye. 
4.4. 
ASSIGNMENT OF PATIENT NUMBER 
Each patient who provides written consent to participate in this study will be assigned a unique 5-
digit PID number (e.g. 01-001) consisting of a 2-digit study center number followed by the 3-digit 
screening number assigned sequentially by each study center, from 001 to 300.  
4.5. 
RANDOMISATION 
Eligible patients will be randomized in a 1:1:1 ratio to either rhNGF eye drops solution 20 µg/ml TID 
(⁓100 patients) or rhNGF  eye drops solution 20 µg/ml BID plus vehicle eye drop solution SID (⁓100 
patients) or vehicle eye drop solution TID (⁓100patients). 
Randomization will be stratified according to absence/presence of a documented diagnosis of Primary 
Sjögren's Syndrome to ensure balanced assignment across treatment groups. 
Each randomized patient will be allocated with randomization number, according to the stratified 
randomization list. Drop outs after randomization will not be replaced. 
Randomization list as well as associated kit numbers will be be generated by a member of Syneos 
Health Biostatistics department, not involved in the conduct of the study.  
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.  
The enrollment of patients will be scheduled in order to assure an inclusion of approximately 240 
patients without Primary Sjögren's Syndrome diagnosis and at least 60 patients  with Primary 
Sjögren's Syndrome.

MASKING 
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 (after 
data base lock) except in case of specific events that will require unmasking of the patient. 
The vials containing rhNGF (20 µg/ml) or vehicle will be identical in appearance, and the contents 
of the vials will be indistinguishable. All staff 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 Syneos Health 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. 
The investigator will be provided with an access, password protected, to the RAVE Randomization 
and Trial Supply Management system (RAVE RSTM) so only in case of a medical emergency the 
Investigator can open the treatment allocation for a specific patient.  
Besides also Dompé Pharmacovigilance contact person will be provided with an access, password 
protected, to the RAVE Randomization and Trial Supply Management system (RAVE RSTM) so if 
required by the Pharmacovigilance activities the Pharmacovigilance contact person can open the 
treatment allocation for a specific Patient. 
 
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. The Investigators are encouraged to contact Syneos Health staff 
before becoming unmasked if there is sufficient time. 
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.  
 
Unmasking events will be recorded and reported in the final study report.

FORMULATION AND PACKAGING  
The Investigator will be provided with a subject monthly box, containing 4 weekly boxes, containing 
7 daily boxes. Each daily box contains three marked vials (e.g. 1- Morning, 2- Afternoon and 3- 
Evening) of frozen IMP solutions (-20 ± 5°C) containing:  
  
• 
rhNGF, at concentrations of 20 µg /mL, and/or  
• 
vehicle (placebo). 
Together with the IMP monthly box, the patients will be provided with a sufficient number of pipette 
and adaptors to be used for the administration of the IMP. 
Pipette and adaptors will be provided separately in single sterile polyethylene packages and may be 
kept at room temperature. 
The pipette is used with an adaptor consisting of a connecting device with dual connections: one 
end for the pipette and one end for the vial.  
The patient 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 pipette on adaptor inlet 
3. Draw the solution contained in the vial with the pipette until this reaches its predetermined 
capacity 
4. Remove the pipette and use it as a dropper to administer one drop of IMP into each eye.

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 1 (baseline visit), the study personnel will give to the patient the monthly boxes containing 
the study medications 
Patient should bring the study medication, one monthly box, at home as soon as possible and 
immediately store it in a freezer at -20 ± 5 °C. 
The weekly box must be kept at 2-8°C for 7 days protected from light; the daily box can be kept at 
room temperature,  before the patient will use the single vial for each instillation (both eyes) as long 
as 12 hours are not exceeded. Agitation of vials may cause foaming and/or particle formation. Drug 
preparation and administration instructions will be provided separately to the site and to the 
patients.  
 
Together with the IMP monthly box, the patient will also receive a separate kit of vial adapters (one 
per vial), pipettes (1 per vial) and disinfectant wipes (1 per vial). 
IMP eye drops solution instruction will be provided to patients.  
Patients will use one vial to instill one drop in both eyes (group 1: rhNGF TID; group 2: rhNGF BID 
and vehicle SID; group 3: vehicle TID) between 7 AM and 9 PM (every 6-8 hours) for 4 weeks . 
The IMP contains L-methionine as an excipient. The contents of each vial are for the daily 
administration to both eyes only. After the last administration the used vial should be returned to the 
original medication box and is not to be reused. 
Any deviations from the recommended storage conditions should be immediately reported by the 
pharmacist to the Sponsor and Investigator, and the use of the drug should be suspended until they 
have given authorization for its continued use. The IMP supplies are to be used only in accordance 
with this protocol. The Investigator will not use any drug samples for other purposes (e.g., treating 
patients or deviating from the protocol with regard to dose regimen, duration of treatment, etc.). Under 
no circumstances will the Investigator give any drug samples to a third party.

5.4. 
DOSE, ROUTE AND SCHEDULE OF IMP ADMINISTRATION 
5.4.1. Administration route 
The Administration route is ophthalmic, the first administration is to be applied by investigator at 
site. 
5.4.2. Dose regimen 
In all patients both eyes will be treated for a period of 4 weeks. 
 
The dosing scheme of the different study groups is summarized below: 
 
Group 1: one drop of rhNGF 20 µg/ml will be instilled in both eyes three times daily (every 6-8 
hours, e.g. 7:00 am, 02:00 pm; 09:00 pm).  
Group 2: one drop of rhNGF 20 µg/ml will be instilled in both eyes two times daily plus one drop 
(40 µL) of vehicle will be instilled in both eyes once daily (every 6-8 hours, e.g. 7:00 am, 
02:00 pm; 09:00 pm). 
NB: rhNGF will be instilled in the morning and in the evening while the vehicle will be 
instilled in the afternoon.  
Group 3: vehicle eye one drop will be instilled in both eyes  three times daily (every 6-8 hours, e.g. 
7:00 am, 02:00 pm; 09:00 pm). 
 
During the 4 weeks of masked treatment only the administration of IMP  is allowed. Nevertheless, if 
strictly needed, the patient can take a preservative free artificial tears (provided by the Sponsor). The 
use (n° drops/day) of preservative free artificial tears will be clearly documented in a patient’s diary 
and in the eCRF.  
Both the patients and the investigator will be masked to the study treatment. 
Information about the  study drug administration, and comments, will be recorded on the 
appropriate page of the eCRF. 
 
5.5. 
ACCOUNTABILITY OF THE IMP 
The Pharmacist and/or Investigator will confirm the receipt of the IMP supply in writing by signing 
and dating standard drug accountability forms. 
At the week 4 (end of treatment visit) the patient will return the used or unused study boxes/vials to 
the Investigator.

The Pharmacist and/or Investigator will keep a cumulative inventory and dispensing records, and will 
maintain all supplies under adequate security.  
An accurate drug disposition record will be kept, specifying the date and amount dispensed to each 
patient.  
Adequate record of receipt and use 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 Syneos Health throughout the duration of the study. 
At the scheduled visit, the patient diary should be reviewed by the Investigator with the patient for 
completeness. Missing information should not be provided during the diary check but reported as 
missing. 
At the conclusion of the study, and during the course of the study, the Investigator will complete the 
drug accountability forms. Partially used or unused study drug boxes will be verified by the 
Investigator and  within one month after completion of the trial the partially used and unused study 
medication will be shipped to the Sponsor or will be destroyed after authorization by the Sponsor by 
an authorized company according to GCP regulations. 
5.6. 
CONCOMITANT MEDICATION 
 
As a general rule, no ophthalmic medication other than study drug will be given to the patient from 
the screening day until all of the final study evaluations have been completed, except for 
preservative free artificial tears.  
The preservative free artificial tears will be provided by the Sponsor and can be used according to 
the following scheme: 
1) During the 4 weeks of masked treatment, only if strictly needed, the patient will instill one 
drop in both eyes. 
2) During the 12 weeks of Follow up period one drop will be instilled in both eyes TID 
(morning, afternoon and evening).  
The use (n° drops/day) of preservative free artificial tears will be clearly documented in the 
patient’s diary and eCRF.  
 
All medications (including over-the-counter drugs, herbal products, vitamins, and antacids) taken 
within 4 weeks prior to the start of and throughout the study will be clearly documented on the 
Concomitant Medications eCRF page. 
Medication entries should be specific to product name (if a combination drug product) and spelled 
correctly. The dose, unit, frequency, route of administration, start date, discontinuation date, and 
indication should also be recorded. For medications administered only one time, the frequency 
column may reflect "once."

6.3. 
EARLY WITHDRAWAL FROM THERAPY OR ASSESSMENT 
6.3.1. 
Primary Reason For Discontinuation From The Study 
A premature discontinuation will occur when a patient who signed the ICF ceases participation in the 
study, regardless of circumstances, before the completion of the study protocol procedures. Patients 
can be prematurely discontinued from the study for one of the following reasons:  
 
¾ Adverse event (AE): Any significant AE that, in the opinion of the Investigator or concerned 
patient,  is not compatible with study continuation. 
¾ Disease progression or worsening, that according to the opinion of the Investigator is not 
compatible with study continuation.. 
¾ Death. 
¾ Lost to follow-up (Every effort must be made to contact the patient; a registered letter must be 
sent). 
¾ Non-compliance with study drug: an indication that a patient has not agreed with or followed 
the instructions related to the study medication. 
¾ Physician decision: a position, opinion or judgment reached after consideration by a physician 
with reference to the patient. 
¾ Severe Protocol violation: an event or decision that stands in contrast to the guidelines set out 
by the protocol. 
¾ Study terminated by the Sponsor: an indication that a clinical study was stopped by Sponsor. 
¾ Withdrawal of consent: study discontinuation requested by a patient for whatever reason. 
¾ Other reasons, such as administrative reasons or pregnancy.  
 
Before removal, each case should first be discussed with Dompé farmaceutici s.p.a. 
The reasons for premature discontinuation from the study will be reflected on the Study Termination 
Record of the eCRF. Unless the patient has withdrawn consent, the follow up visit assessments should 
be performed as detailed in § 6. 
 
The investigator should advise patients that prematurely discontinue on any therapies or treatments 
for their condition and refer them for further treatment as appropriate

6.3.2. 
Discontinuation procedures 
For any patient discontinuing the study following randomization, the Investigator will:  
 
¾ ask the patient to undergo, as far as possible, a final medical visit (ETV) to examine the patient's 
health conditions. This examination will verify that all values tested at screening have remained 
within a clinically acceptable range (i.e., not clinically significant changes compared to 
screening). 
¾ arrange for alternative medical care of the withdrawn patient, if necessary. 
¾ report in the eCRF date and time of the last dose administration, and date and primary reason of 
study discontinuation. 
¾ record in the eCRF any follow-up if the patient is withdrawn for an AE. AE’s should be followed 
until resolution. 
 
 
6.3.3. Replacement procedure 
Patients in this study who prematurely discontinue treatment will not be replaced. 
 
It will be documented whether or not each patient completed the clinical study. If, for a patient, 
study treatment or observations are discontinued, the primary reason for discontinuation will be 
recorded. 
 
6.4. 
END OF STUDY 
Patients completing the double-blind treatment (Visits 1 Baseline to Visit 6 Follow up) will be 
considered completers.  
For the purpose of this trial, the End of Study is defined as 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.

8. EVALUATION OF ADVERSE EVENTS AND SAFETY INFORMATION 
8.1. 
DEFINITIONS  
Adverse Event 
An Adverse Event (AE) is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a medicinal product and which does not necessarily have a causal 
relationship with this treatment. 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 product, whether or not related to the medicinal product.  
Adverse Drug Reaction  
An Adverse Drug Reaction (ADR) is defined as any noxious and unintended response to a medicinal 
product related to any dose. Any responses to a medicinal product means that a causal relationship 
between a medicinal product and an adverse event is at least a reasonable possibility, i.e., the 
relationship cannot be ruled out. 
The definition covers also medication errors and uses outside what is foreseen in the protocol, 
including misuse and abuse of the product. For the purposes of IND safety reporting, “reasonable 
possibility” means there are facts (evidence) or arguments to suggest a causal relationship between 
the drug and the adverse event..  Adverse events are to be considered unrelated if the relationship to 
the study drug, as described in the table in § 8.2.1,  is none or unlikely; whereas any AE reported in 
the study having a possible, probable or highly probable relationship to study drug will be considered 
as an ADR. The determination of expectedness should be made by the Sponsor on the basis of the IB. 
Serious Adverse Event 
A Serious Adverse Event (SAE) is defined in line with (CFR - Code of Federal Regulations Title 
21 Sec. 312.32) as any adverse experience that, in the view of either the Investigator or sponsor, meets 
any of the following criteria:: 
x results in death, 
x is life-threatening (i.e. the patient was at immediate risk of death at the time of the event. It does 
not refer to an event which hypothetically might have caused death if it were more severe), 
x 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 outpatient setting. Complications that occur during 
hospitalization are AEs. If a complication prolongs hospitalization or fulfills any other serious 
criteria, the event is serious. When in doubt as to whether “hospitalization” occurred, the event 
should be considered serious.

x 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, diarrhea, influenza, or accidental 
trauma (e.g., sprained ankle) which may interfere or prevent everyday life functions but do not 
constitute a substantial disruption 
x is a congenital anomaly/birth defect, 
x 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 wellbeing 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. 
8.3.2).   
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.  
Death shall always be reported as SAE and cause of death shall always be specified when known. 
Unexpected Adverse Event/Reaction 
An AE or ADR is considered unexpected if it is not listed in the Investigator Brochure or is not listed 
at the specificity or severity that has been observed and listed in the Investigator Brochure. Events 
that are mentioned in the Investigator Brochure (section Reference Safety Information)  as occurring 
with a class of drugs or as anticipated from the pharmacological properties of the drug, but are not 
specifically mentioned as occurring with the particular drug under investigation are considered 
unexpected (21 CFR312.32(a)). 
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. 
As mentioned, the determination of expectedness should be made on the basis of the IB (section 
Reference Safety Information)  .

Adverse Events (AEs) 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): 
¾ AEs 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 
¾ AEs that caused a decrease in visual acuity to the level of Light Perception or worse lasting >1 
hour 
¾ AEs 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 
¾ AEs associated with severe intraocular inflammation (i.e., 4+ anterior chamber cell/flare or 4+ 
vitritis) 
¾ AEs that, in the opinion of the Investigator, may require medical intervention to prevent 
permanent loss of sight. 
8.2. 
ADVERSE EVENT (AE) MONITORING 
At visit 3 (end of treatment), visit 4 (FU), vist 5 (FU) and visit 6 (FU), 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:  
x “Have you had any health problems since your last study visit?” 
x “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 condition(s) that is the result 
of an untoward (unfavorable 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 (unfavorable 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. 
All AEs should be followed-up to determine outcome of the reaction.  
In order to collect as complete as possible information in the clinical study database, all ADRs and SAEs 
ongoing at the time the subject’s study participation ends should be evaluated within 10 days after the 
final visit. After this period, all unresolved ADRs and SAEs will be reported as “ongoing” in the eCRF.

8.3. 
RECORDING 
AE data should be obtained through observation of the patient, from any information volunteered by 
the patient, or through patient questioning. 
 
Adverse Events: 
All AEs (non-serious and serious) that 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) should be specified in the dedicated eCRF 
sections. Subsequent to signing an informed consent form, all untoward medical occurrences that 
occur during the course of the study must be documented on eCRF. AEs will be collected till last 
Follow Up visit (week 16). 
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 adverseevent 
relationship to the study treatment. 
 
 
Serious Adverse Events: 
The Investigator must record all SAEs, including sight-threatening events, occurring at any time 
during the study regardless of presumed causal relationship, on the Serious Adverse Event form in

8.3.1. 
Relationship of AEs to the Investigational Product 
The Investigator will assess the possible relationship between the AE and the investigational 
medication, according to the criteria in Table below: 
Relationship of the Adverse Event to the IMP 
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 or surgical intervention performed 
during the study, but planned before patient enrolment into the study 
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 more 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 
 
An ADR is defined as an adverse experience which is reasonably likely to have been caused by the 
drug. Events considered “Possible”, “Probable” and “Highly Probable” related to the IMP treatment 
and implying a reasonable possibility, if considered unexpected, will be reported to appropriate 
regulatory authorities. 
8.3.2. 
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. 
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])

8.4. SERIOUS ADVERSE EVENT REPORTING 
8.4.1. 
Reporting Procedure for Investigators to Dompé and CRO 
The Investigator must report all SAEs filling in and signing a SAE Report form, including sight 
threatening events, regardless of presumed causal relationship, to Dompé Drug Safety and Syneos 
Health Pharmacovigilance, by e-mail (preferred) or fax within 24 hours of learning of the event.

Page 70 of 90 
 
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”.   
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. 
An assessment of expectedness and causality of each serious adverse event will be performed case 
by case by Dompé/Syneos Health. For SAE reported by the Investigator as not related that is 
subsequently assessed to be related by Dompé, the Investigator will receive a notification. Depending 
on the nature and seriousness of the AE, further information, including copies of appropriate medical 
records of the patient, as well as results of laboratory tests performed will need to be included in the 
patients chart. If the patient was hospitalized, a copy of the discharge summary should be available, 
if possible. 
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 the the 
Dompé/Syneos Health Pharmacovigilance. 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.  
8.4.2. 
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: 
x 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.  
x Hospitalization for routine treatment or monitoring of the studied indication, not associated 
with any deterioration in condition. 
x 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. 
x Hospitalization for general care not associated with any deterioration in condition.  
x 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, the following situation shall not be considered SAE: 
 
x Trial end points 
x Abnormal test results that do not induce clinical signs and/or symptoms and require 
intervention/therapy, i.e. are not clinically significant. 
8.4.3. 
Reporting Procedure to IRB and to Regulatory Authorities 
In addition to reporting the SAE to Dompé, the Investigator must also comply with the requirements 
related to the reporting of SAEs to the IRB which approved the study. The requirements of IRBs vary 
from one IRB to another; however, as a minimum requirement, the Investigators must promptly report 
all suspected unexpected serious adverse reaction (SUSAR) to their IRB. 
In line with provisions set forth in 21CFR312, Dompé shall notify all participating Investigators in 
an IND safety report of any suspected adverse reaction that is both serious and unexpected  and of 
potential serious risks, from clinical trials or any other source, as soon as possible, but in no case later 
than:  
x seven calendar days after becoming aware of the information if the event is fatal or life 
threatening; to be followed by any relevant information within eight days. 
x fifteen calendar days after becoming aware of the information if the event is serious but neither 
fatal nor life threatening. 
The Investigators in turn shall notify their IRB.  
If the results of an investigation show that an ADR not initially determined to be reportable is 
reclassified as reportable, the Sponsor shall report such reaction in a written safety report as soon as 
possible, but in no event later than 7/15 calendar days after the determination is made. 
Treatment will be unblinded by Dompé Drug Safety Pharmacovigilance prior to submission of a 
SUSAR to Regulatory Authorities and only cases referred to active treatment will be considered 
expeditable for regulatory reporting, in line with law requirements. 
Copies of all correspondence relating to reporting of any SAEs to the IRB should be maintained in 
the Investigator’s Files. 
Dompé shall also notify FDA in an IND safety report of potential serious risks, from clinical trials or 
any other source, as soon as possible after Dompé determines that the information qualifies for 
reporting, in particular shall notify of: 
x any suspected adverse reaction that is both serious and unexpected. Dompé must report an 
adverse event as a suspected adverse reaction only if there is evidence to suggest a causal 
relationship between the drug and the adverse event.

x findings from other studies that suggest a significant risk in humans exposed to the drug. Such a 
finding would result in a safety-related change in the overall conduct of the clinical investigation.  
x findings from animal or in vitro testing that suggest a significant risk in humans exposed to the 
drug 
x increased rate of occurrence of serious suspected adverse reactions. 
8.4.4. 
Periodical Reporting to Regulatory Authorities 
Dompé shall be responsible to prepare and submit annual safety reports (Development Safety Update 
Report – DSUR) to relevant Regulatory Authorities.  
8.5. 
UNMASKING OF THE STUDY TREATMENT 
Masked information on the identity of the assigned investigational product will be provided for each 
patient. If the treatment code needs to be broken in the interest of patient safety, Dompé must be 
informed in all cases in which the code was broken and of the circumstances involved. 
Additionally, Dompé Drug Safety may be need to unmask the patient’s treatment if the a reported 
SAE meets criteria of a Suspected Unexpected Serious Adverse Reaction (SUSAR) in order to fulfil 
expedited regulatory reporting requirements. Unmasked information shall not be disclosed to 
Investigators. 
The identity of the treatments will remain unknown to the patient, Investigator, site staff and Dompé’s 
clinical research personnel and Syneos Health staff (apart from pharmacovigilance). 
8.6. 
FOLLOW-UP OF PATIENTS WITH ADVERSE EVENTS (AES) 
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. 
If patient was hospitalized due to a SAE, a copy of the discharge summary is to be forwarded to 
Syneos Health/Dompé as soon as it becomes available. In addition, a letter from the Investigator that 
summarizes the events related to the case as well as results of any relevant laboratory tests also may 
be requested. Further, depending upon the nature of the SAE, Dompé may request copies of applicable 
segments of the patient’s medical records.

For pharmacovigilance purposes, all SAEs should be followed-up in order to elucidate as completely and 
practically as possible their nature and/or causality until resolution of all queries, clinical recovery is 
complete, laboratory results have returned to normal, stable condition is reached or the subject is lost to 
follow-up. Follow-up may therefore continue until after the subject has left the study up to  10 days after 
his/her discontinuation from the study for unrelated SAEs, and without timelines for related SAEs, unless 
the patient denies consent. 
8.7. 
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 enrollment 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 (during the study treatment period and during the 
follow up), 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 as soon as possible 
(within 24 hours of learning of the pregnancy) to  Syneos Health/Dompé Drug Safety contacts 
reported at Paragraph 8.4.1, even if no AE has occurred, and follow it to term.  
The pregnancy form will be utilized to capture all pregnancy-related information until the birth of 
the child for both the patient and the partner.  
If the pregnancy is associated with a 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 § 8.4 
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 leads 
to the immediate cessation of the study treatment.  
8.8. 
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.

8.9. 
OVERDOSE  
Cases of overdose (accidental or intentional) which may or may not result in serious adverse reactions 
are to be reported to Sponsor Drug Safety/Syneos Health by email or fax, following the same 
procedure for SAE, within 24 hours from the Investigator’s knowledge of its occurrence. This 
includes reports related to 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. 
The Investigator shall provide in the SAE form information about symptoms, corrective treatment 
and outcome of overdose.

STATISTICS 
 
The data documented in this study will be summarized using number of observations, mean, standard 
deviation (SD), median, minimum, and maximum values for quantitative variables, and frequencies 
for qualitative variables. 
A statistical analysis plan (SAP) will be developed and finalized before database lock and de-
masking. Final statistical analysis on the study variables will be presented in detail in the SAP.  
9.1. 
SAMPLE SIZE 
In order to evaluate the minimal effective daily dose of rhNGF eye drops, a Williams design has been 
chosen [15; 16]. For this study three treatment groups has been considered: rhNGF eye drops solution 
20 µg/ml TID; rhNGF  eye drops solution 20 µg/ml BID plus vehicle eye drop solution SID; vehicle 
eye drop solution TID. 
To this purpose, the sample size has been determined applying the formula eported in the publication 
Chow et al., 2008 at page 301 [17].  
 
The sample size calculation for the primary variable is based on the following assumptions: 
 
 The probability level (α) for one-sided test is set at 0.025 (see table 12.1.2 at page 298 in Chow 
et al., 2008) and the power level at approximately 90%. 
 
 DELTA, in change from baseline between treatments, of 5.3 and Standard Deviation for DELTA 
of 10.78. Both DELTA parameters are derived from results of co-variance analysis obtained from 
study NGF0216 in the subset of hyposecretive patients (i.e. excluding “evaporative-only” 
patients). 
 
According to this calculation, 87 patients per treatment group (for a total of 261 patients) are 
adequate to observe the planned difference assumed for the minimum effective daily dose. 
Assuming a drop-out of ⁓15%, a total of 300 is the target number of patients proposed to be 
enrolled.  
 
The inclusion of at least 60 subjects with documented diagnosis of Primary Sjögren's Syndrome 
within the planned 300 patients will have no impact on the initial study assumptions (Standard 
Deviation of 10.78 and DELTA of 5.3 mm) because the patients could have been enrolled based on the 
previous criteria on which sample size was based. Moreover, a similar prevalence of patients with 
Primary Sjögren's Syndrome has already been reported in the NGF0216 medical history (⁓25% of 
patient the FAS population).

POPULATION 
Screened Population  
The Screened Population will consist of all patients with the signature of the informed consent, the 
assignment of a PID number and regardless the completion of all the screening procedures.  
Eligible Population 
The Eligible Population will consist of all patients with all inclusion/exclusion criteria met. Otherwise 
the patient will be defined as screening failure.  
 Randomized Population  
The Randomized Population will consist of all patients in the Screened Population who were assigned 
a randomization number.  
9.3. 
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 1 Visit 1 baseline and the number of unused study 
medication vials returned at Week 4 Visit 3 End of treatment. The percentage Compliance will be 
evaluated according to the following formula: 
𝐎𝐯𝐞𝐫𝐚𝐥𝐥 𝐜𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐜𝐞= 𝟏𝟎𝟎∗(Number of vials dispensed –  Number of unused vials returned)
𝟑∗(𝑵𝒖𝒎𝒃𝒆𝒓𝒔 𝒐𝒇 𝒅𝒂𝒚𝒔 𝒐𝒏 𝒕𝒓𝒆𝒂𝒕𝒎𝒆𝒏𝒕)
 
 
𝐂𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐜𝐞 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐞𝐥𝐢𝐠𝐢𝐛𝐥𝐞 𝐞𝐲𝐞= 𝟏𝟎𝟎∗(Number of  drops administered to the eligible eye)
𝟑∗(𝑵𝒖𝒎𝒃𝒆𝒓𝒔 𝒐𝒇 𝒅𝒂𝒚𝒔 𝒐𝒏 𝒕𝒓𝒆𝒂𝒕𝒎𝒆𝒏𝒕)
 
 
Gross non compliance will be defined as compliance lower than 80% or greater than 120% and in 
case of gross non compliance the patient will be excluded from the Per Protocol. Since this definition 
does not warrant that the study eye treatment is compliant, if indicated the SAP will contain further 
definitions based upon the diary card information.

STATISTICAL METHODOLOGY 
9.4.1. 
Definitions 
Enrolled Set  
The Enrolled Set will consist of all patients who signed the ICF. This analysis set will be used for 
demographic, baseline and background characteristics. 
Safety Population 
The Safety Population (SAF) will consist of all randomized patients who took at least one dose of IP. 
This analysis set will be used for the safety analysis. Patients will be analyzed according to the 
treatment received. 
Full Analysis Set 
Full Analysis Set (FAS) will consist of all randomized patients who took at least one dose of IP and 
who have at least one post-baseline efficacy measurement for the primary endpoint. This analysis set 
will be used for the primary efficacy analysis. Patients will be analyzed according to the randomized 
treatment. 
Per Protocol Set 
Per Protocol Set (PP) will consist of all patients in the FAS who fulfil the study protocol requirements 
in terms of investigational medicinal product intake and collection of primary efficacy data and with 
no major deviations that may affect study results. This analysis set will be used for supportive efficacy 
analysis.Patients will be analyzed according to the treatment received. 
Each patient will be coded by the Syneos Health statistician as valid or not valid for the Enrolled Set, 
SAF, FAS and PP. 
9.4.2. 
Reasons for exclusion from the Full Analysis Set 
Reasons for the exclusion from the Full Analysis Set are the following: 
¾ 
failure to take at least one dose of the IMP at the study eye 
¾ 
lack of any efficacy data post enrollment. 
9.4.3. 
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:

9.4.4. 
Demographic and baseline characteristics 
Demographic and baseline characteristics will be descriptively summarized per treatment group 
according to their nature.  
9.5. 
Analysis of ophthalmological evaluations  
Primary endpoint will be analyzed using analysis of variance including only the treatment as main 
factor followed by pre-planned comparisons from Vehicle and rhNGF dosages according to Williams 
procedure. In addition, primary endpoint will be summarized using descriptive statistics for 
continuous variables by treatment and visit. The change from baseline value will also be summarized 
for all post-baseline visits. 
An explorative sensitivity analysis of the primary endpoint will be conducted including in the analysis 
of variance the absence/presence of diagnosis of Primary Sjögren's Syndrome and its interaction with 
treatments as covariates. If the interaction term is statistically significant (at the 0.10 level given its 
explorative nature), the treatment effects within patients with and without Primary Sjögren's 
Syndrome will be provided. 
 
Secondary endpoints will be presented by means of appropriate descriptive statistics.  
Changes from baseline in global SANDE score, Schirmer test II, NEI scales, TFBUT,  IDEEL, PGIC 
and EQ-5D-3L scores 4 will be analyzed in a similar manner as the Change from baseline in Schirmer 
test I (primary endpoint) in order to test treatment effect. Difference between treatment groups (Each 
active dose vs Placebo), in the percentage of patients who experienced a worsening in SANDE scores 
and/or NEI score will be tested using a chi-square test. 
 
Explorative endpoints will be summarized by means of appropriate descriptive statistics. Any 
statistical testing will be descriptive in nature. 
 
Additional details on the analyses will be provided in the statistical analysis plan.

Analysis of safety variables 
x AEs 
Adverse events (AEs) will be coded by System Organ Class (SOC) and Preferred Term (PT), using 
the Medical Dictionary for Regulatory Activities (MedDRA). 
Treatment-emergent AEs are all events occurring or worsening after the first dose of the IMP. 
Treatment-emergent AEs will be summarized by treatment group. 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. Individual AEs will be listed in patient data listings.   
9.5.2. 
 Analysis of Quality of Life variables  
Data record in the questionnaires of quality of life will be presented with appropriate descriptive 
statistics and processed with appropriate inferential test. 
 
9.5.3. 
Subgroup analysis 
Sub-group analyses of primary, secondary, explorative endpoints and safety endpoints will be 
performed on patients with the Sjögren's syndrome  for explorative purpose. Statistical details will be 
reported in the SAP. 
 
9.5.4. 
Changes to the statistical plan 
Any deviations from the original statistical plan will be escribed in the Clinical Study Report.

ETHICAL CONSIDERATIONS 
10.1. 
INSTITUTIONAL REVIEW BOARD  
Approval by the Institutional Review Board (IRB) before the start of the study will be the 
responsibility of the Principal Investigator (PI). A copy of the approval letter will be supplied to the

DATA HANDLING AND RECORD KEEPING  
11.1. 
CASE REPORT FORMS 
All data relating to the study will be recorded on eCRFs to be provided by  Syneos Health, through 
the EDC system. The PI is responsible for verifying that all data entries in the eCRFs are accurate 
and correct. The PI must sign the completed eCRF before its submission to the sponsor.  
11.2. 
DATA MANAGEMENT  
Data collection will involve the use of an EDC system , to which only authorized personnel will have 
access. In addition to periodic monitoring occurring within the system by Syneos Health Monitors, 
programmatic edit checks will be used to review the data for completeness, logic, and adherence to 
study protocol. As a result of this monitoring and these checks, queries may be electronically issued 
to the study centers and electronically closed by those study centers. The identifying information 
(assigned username, date, and time) for both the originator of the query (if created during the 
monitoring process) and the originator of the data change (if applicable), as well as the PI’s approval 
of all changes performed on his or her patients’ data, will be collected.  
All data collected in the context of this study will be stored and evaluated per regulatory requirements 
and applicable guidances for electronic records. Also, data will be stored and evaluated in such a way 
as to guarantee patient confidentiality in accordance with the legal stipulations applying to 
confidentiality of data. Study records (e.g., copies of eCRFs, regulatory documents) will be retained 
at the study center, along with adequate source documentation, according to FDA and ICH 
requirements. All study records must be available for audit  by Dompé farmaceutici s.p.a.; its 
authorized representatives; and Regulatory Inspection by Regulatory Authority.  
The investigator/institution should maintain adequate and accurate source documents and trial records 
that include all pertinent observations on each of the site’s trial subjects. Source data should be 
attributable, legible, contemporaneous, original, accurate, and complete. Changes to source data 
should be traceable, should not obscure the original entry, and should be explained if necessary via 
an audit trail. 
11.3. 
DOCUMENTATION REQUIRED PRIOR TO INITIATION OF AND DURING THE 
STUDY 
The following documents will be required from the Investigator prior to the initiation visit: 
- 
Current, signed and dated Curriculum Vitae of Principal Investigator and any 
Sub-Investigators/co-workers. Updates should be provided at least every two years.

11.4. 
ESSENTIAL DOCUMENT RETENTION 
The Investigator will retain copies of all the essential documents (as defined by ICH-GCP E6 R2) 
until at least 2 years after the last approval of a marketing application in an ICH region, and until 
there are no pending or contemplated marketing applications in an ICH region, or at least 2 years 
have elapsed since the formal discontinuation of clinical development of the Investigational Product. 
These documents should be retained for a longer period however if required by the applicable 
regulatory requirements. The Investigator should take measures to prevent accidental or premature 
destruction of these documents. 
The essential documents include at least: the signed protocol, copies of the completed eCRFs, signed 
Patient Informed Consent Forms from all patients who consented, hospital records and other source 
documents, and all other documentation included in the Investigator Site File and 
Pharmacy/Dispensing File. 
The Investigator will inform Dompé farmaceutici s.p.a. of the storage location of these essential 
documents and must contact Dompé farmaceutici s.p.a. before disposing of any. If the Investigator 
wishes to assign the files to someone else or to remove them to another location, he/she should consult 
with Dompé farmaceutici s.p.a. about this change. 
Dompé farmaceutici s.p.a. will inform the Investigator in writing when these documents no longer

STUDY MANAGEMENT 
 
The study will be performed in accordance with the protocol, the Declaration of Helsinki (64th WMA 
General Assembly, Fortaleza, Brazil, October 2013) and ICH Harmonised Tripartite Guideline for 
Good Clinical Practice (ICH-GCP E6-R2) and any local regulations. 
12.1. 
MONITORING 
Before any patient enters the study, a representative of Syneos Health, will meet with the PI and his 
or her staff to review the procedures to be followed during the study and to train them on recording 
the data in the eCRFs using the electronic data capture (EDC) system. After the first patient is 
enrolled, the Syneos Health representative, a monitor, will periodically monitor the progress of the 
study by conducting on-site visits. This CRA will also be able to review query statuses remotely, 
possibly warranting more frequent communication with the PI and his or her staff. The PI will make 
available to the CRA the eCRFs, source documents, signed consent forms, and all other study-related 
documents. The PI and his or her staff will be responsible for reviewing eCRFs, resolving data queries 
generated by the CRA via the system, providing missing or corrected data, approving all changes 
performed on his or her data, and endorsing the patient data within the EDC system. This approval 
method will include applying an electronic signature, a uniquely assigned username and password 
that together will represent a traditional handwritten signature.  
12.2. 
ACCESS TO RECORDS 
The Investigator will allow designated Dompé farmaceutici s.p.a. representatives, including staff 
from Syneos Health, and regulatory/ethics bodies to have direct access to the source documents to 
verify the data reported in the eCRFs. Source documents are the originals of any documents used by 
the Investigator or hospital/institution that allow verification of the existence of the patient and 
substantiate the integrity of the data collected during the trial. 
12.3. 
AUDIT AND INSPECTION 
The study site may be audited by Syneos Health on behalf of the Dompé farmaceutici s.p.a. or 
inspected by a regulatory agency on one or more occasions. The Investigator may be informed in 
advance of such a visit.  
12.4. 
PROTOCOL AMENDMENTS 
Any amendment to this protocol will be provided to the PI in writing by Dompé farmaceutici s.p.a. 
No protocol amendment may be implemented (with the exceptions noted below) before it has been

approved by the IRB and the signature page, signed by the PI, has been received by Dompé 
farmaceutici s.p.a. If the protocol is amended to eliminate or reduce the risk to patients, the 
amendment may be implemented before IRB review and approval. However, the IRB must be 
informed in writing of such an amendment, and approval must be obtained within reasonable time 
limits. Deviating from the protocol is permitted only if absolutely necessary for the safety or clinical 
management of the patients and must immediately be reported to Dompé farmaceutici s.p.a. 
12.5. 
DISCONTINUATION OF THE STUDY 
Dompé farmaceutici s.p.a. reserves the right to terminate the study in its entirety or at a specific 
study center at any timeon the basis of new information regarding safety or efficacy, or if study 
progress is unsatisfactory, or for other valid administrative reasons. 
12.6. 
PUBLICATIONS 
All data generated in this study will be the property of Dompé farmaceutici s.p.a. Publication of the 
results by the PI will be subject to mutual agreement between the PI and Dompé farmaceutici s.p.a. 
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 FDA 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.

Purpose 
The purpose of this statistical analysis plan (SAP) is to ensure that the data listings, summary tables 
and figures which will be produced, and the statistical methodologies that will be used, are complete, in 
line with study protocol version 2.0 of 08 August 2019, and appropriate to allow valid conclusions 
regarding the study objectives. 
Due to restrictions in the hospital clinical routines related to COVID-19 pandemic started in March 2020, 
Dompé has decided to stop prematurely enrollement in the study in order to comply with quarantine 
measures of each country and avoid risks of infection of COVID-19 illness itself for all involved subjects. 
The study stopped to 261 patients instead of 300 originally planned; last subject enrolled was on March 
25th, 2020. On March 9th, 2020 256 patients were randomized. Among them 185 had completed the 
study and 44 were early terminated subjects. So only 27 subjects are ongoing and 5 not randomized at 
the time of national emergency due to COVID-19. 
Patients affected by COVID-19 will be identified using through Adverse form and Meddra coding 
(Peferred Term = ‘Coronavirus infection’). 
 
Data collection and management of visits during COVID-19 pandemic 
When possible, subject visits should occur in person, but in order to avoid any issues (e.g. unexpected 
site closure) that may affect subjects treatment, safety and data collection, Dompé allowed sites to 
perform remote subjects visits when an in-person visit(s) is not able to occur.  
Remote subject visits is organized in advance as a preventive action plan should the sites close 
unexpectedly or a subject is unable/unwilling to come to the site for a visit(s). 
If an in-person subject visit cannot occur as scheduled or be scheduled out of window because of site 
closure or of a subjects inability/unwillingness to come to the site, than a telephone (remote) visit should 
occur in place of the onsite visit(s). 
When a site deems that a remote subject visit is required, SANDE questionnaire, IDEEL, EQ-5D-3L 
PGIC and diaries will be completed by the subject at home. Once the completed questionnaires and 
diaries are received by the site, the site should set up a telephone visit with the subject  to review the 
completed questionnaire and diaries and evaluate the safety. 
 
Responsibilities 
Syneos Health will perform the statistical analyses and are responsible for the production and quality 
control of all tables, figures, and listings.  
 
Timings of Analyses 
The primary analysis of safety and efficacy data is planned after all patients complete the final study 
visit or terminate early from the study.

Study Objectives 
 
Study Objective 
The study objective is to assess the efficacy and safety of recombinant human nerve growth factor 
(rhNGF) when administered as eye drops to patients with moderate to severe dry eye and to 
exploratively evaluate the preliminary efficacy data also in a group of dry eye patients with diagnosis 
of Primary Sjögren's Syndrome. 
 
Brief Description 
This is a phase II, multicenter, randomized, double-masked, vehicle-controlled, parallel group study 
designed to perform dose ranging and evaluate efficacy of rhNGF eye drops at 20 µg/mL concentration 
administered two or three times daily for 4 weeks in patients with moderate to severe dry eye. 
Patients will be evaluated at screening visit (day -8), baseline (Day 1), Week 2 (14 ± 2), Week 4 (Day 
28 ± 2) or early withdrawal and Week 8 (Day 56 ± 2), Week 12 (Day 84 ± 4), Week 16 (Day 112 ± 7) of 
follow-up.

Determination of Sample Size 
In order to evaluate the minimal effective daily dose of rhNGF eye drops, a Williams design has been 
chosen [1] [2]. For this study three treatment groups have been considered: rhNGF eye drops solution 
20 μg/mL TID; rhNGF eye drops solution 20 μg/mL BID plus vehicle eye drop solution SID; vehicle 
eye drop solution TID.  
 
To this purpose, the sample size has been determined applying the formula reported in the 
publication Chow et al., 2008 at page 301 [3] 
 
The sample size calculation for the primary variable is based on the following assumptions:  
 
- 
The probability level (α) for one-sided test is set at 0.025 (see table 12.1.2 at page 298 in 
Chow et al., 2008[3]) and the power level at approximately 90%.  
  
- 
DELTA, in change from baseline between treatments, of 5.3 and Standard Deviation for 
DELTA of 10.78. Both DELTA parameters are derived from results of co-variance analysis 
obtained from study NGF0216 in the subset of hyposecretive patients (i.e., excluding 
“evaporative-only” patients).  
 
According to this calculation, 87 patients per treatment group (for a total of 261 patients) are adequate 
to observe the planned difference assumed for the minimum effective daily dose. Assuming a drop-
out of about 15%, a total of 300 is the target number of patients proposed to be enrolled. 
The inclusion of at least 60 subjects with documented diagnosis of Primary Sjögren's Syndrome within 
the planned 300 patients will have no impact on the initial study assumptions (Standard Deviation of 
10.78 and DELTA of 5.3 mm) because the patients could have been enrolled based on the previous 
criteria on which sample size was based. Moreover, a similar prevalence of patients with Primary 
Sjögren's Syndrome has already been reported in the NGF0216 medical history (~25% of patient the 
FAS population). 
Impact on the power of the study due to stopping enrollment in the study to 261 randomized subjects:

Page 13 of 64 
With 261 patients randomized, assuming a drop out rate of 15%, only 228 patients in total  (76 
patients by group) are considered adequate to observe the planned difference assumed for the 
minimum effective daily dose.  
With 76 patients by group, with a DELTA, in change from baseline between treatments of 5.3 and 
Standard Deviation for DELTA of 10.78, the power to detect a difference will be at least 85%. 
 
 
Treatment Assignment & Masking 
Eligible patients will be randomized in a 1:1:1 ratio to either rhNGF eye drops solution 20 μg/mL TID 
(100 patients) or rhNGF eye drops solution 20 μg/mL BID plus vehicle eye drop solution SID (100 
patients) or vehicle eye drop solution TID (100 patients).  
 
Following amendment n° 1 to the protocol, randomization will be stratified according to 
absence/presence of a documented diagnosis of Primary Sjögren's Syndrome.  
The study was ongoing at the time of amendment and at the beginning of September 135 patients 
had already been randomized. The randomization list generated on March 22, 2019 will be stopped 
when the last randomization number used will be at the end of a block. Moving forward, the 
replacement list will be used. According to the amendment n° 1, the replacement randomization 
schedule will be stratified according to absence/presence of a documented diagnosis of Primary 
Sjögren's Syndrome. 
Each randomized patient after amendment will be allocated with randomization number, according to 
the stratified randomization list using an Interactive Web Response System (IWRS). 
Drop outs after randomization will not be replaced.  
 
Randomization lists as well as associated kit numbers will be generated by a member of Syneos 
Health Biostatistics department, not involved in the conduct of the study.  
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. 
 
The enrollment of patients will be scheduled in order to assure an inclusion of approximately 240 
patients without Primary Sjögren's Syndrome diagnosis and at least 60 patients with Primary 
Sjögren's Syndrome. 
 
For patients already enrolled in the study, the assignment to a strata will be based on Medical history 
form (see section 8.1). 
 
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 (after data base 
lock) except in case of specific events that will require unmasking of the patient.  
 
The vials containing rhNGF (20 μg/mL) or vehicle will be identical in appearance, and the contents of 
the vials will be indistinguishable. All staff directly involved in the analysis of study results will remain 
masked to treatment assignments while the study is in progress.  
 
If the Investigator becomes unmasked for any reason, this information will be recorded on source data 
and in the electronic case report form (eCRF) of the study, specifying the date and the reason.  
Unmasking events will be recorded and reported in the final study report. 
 
 
Administration of Study Medication 
On Day 1 (baseline visit), the study personnel will give to the patient the monthly box, containing 4 
weekly boxes, each containing 7 daily boxes. Each daily box contains three marked vials (e.g., 1 - 
Morning, 2 - Afternoon and 3 - Evening) of frozen investigational medicinal product (IMP) solutions (-
20 ± 5°C) containing:

Page 14 of 64 
 
• rhNGF at concentrations of 20 μg/mL, and/or 
• vehicle (placebo). 
 
Patient should bring the study medication, one monthly box, at home as soon as possible and 
immediately store it in a freezer at -20 ± 5 °C. The weekly box must be kept at 2-8°C for 7 days 
protected from light; the daily box can be kept at room temperature, before the patient will use the 
single vial for each instillation (both eyes) as long as 12 hours are not exceeded. 
 
The administration route is ophthalmic; the first administration is to be applied by investigator at site. 
In all patients, both eyes will be treated for a period of 4 weeks.  
 
The dosing scheme of the different study groups is summarized below:  
 
• 
Group 1: one drop of rhNGF 20 μg/mL will be instilled in both eyes three times daily (every 6-
8 hours, e.g., 7:00 am, 02:00 pm; 09:00 pm).  
 
• 
Group 2: one drop of rhNGF 20 μg/mL will be instilled in both eyes two times daily plus one 
drop (40 μL) of vehicle will be instilled in both eyes once daily (every 6-8 hours, e.g., 7:00 am, 
02:00 pm; 09:00 pm).  
NB: rhNGF will be instilled in the morning and in the evening while the vehicle will be instilled in the 
afternoon.  
 
• 
Group 3: vehicle eye one drop will be instilled in both eyes three times daily (every 6-8 hours, 
e.g., 7:00 am, 02:00 pm; 09:00 pm).

Analysis Sets 
 
Enrolled Set 
The Enrolled Set will consist of all patients who signed the ICF.  
This analysis set will be used for patients disposition and some listings. 
 
Randomized Set 
The Randomized Set will consist of all patients who signed the ICF and were subsequently 
randomized into the study, regardless of study treatment administration.   
 
Safety Analysis Set   
The Safety Analysis Set (SAF) will consist of all patients in the Randomized Set who took at least one 
dose of investigational product (IP) . This analysis set will be used for the safety analysis. Patients will 
be analyzed according to the treatment received. 
 
Full Analysis Set  
Full Analysis Set (FAS) will consist of all patients randomized who took at least one dose of IP and 
who have at least one post-baseline efficacy measurement for the primary endpoint. This analysis set 
will be used for the primary efficacy analysis. Patients will be analyzes according to the randomized 
treatment. 
 
Per Protocol Set  
Per Protocol Set (PP) will consist of all patients in the FAS who fulfil the study protocol requirements 
in terms of IMP intake and collection of primary efficacy data and with no major deviations that may 
affect study results. This analysis set will be used for supportive efficacy analysis.  
Patients will be evaluated according to the treatment dose they will actually receive.  
 
Protocol Deviations 
Important protocol deviations will be collected in the eCRF and CTMS. Each instance of a protocol 
deviation will be determined to be either significant or not. Protocol deviations linked to COVID-19 will 
be identified with “COVID-19 XXXXXX”.  
  
The major protocol deviations include, but are not limited to, the following (to be finalized before 
database lock):  
 
• 
Non compliance with IP administration (less than 80% or more than 120%); 
• 
missing primary efficacy data; 
• 
Major deviation from  inclusion/exclusion criteria (eligibility violations) (will be defined in blind 
conditions in the last blind data review meeting before database lock); 
• 
intake of prohibited medications. 
Protocol deviations will be reviewed during the course of the study and prior to database lock. 
Patients with any major protocol deviations listed above will not be included in the PP set. 
Number (%) of patients with at least one major protocol deviation  leading to exclusion of subject from 
the Per-protocol will be included in a summary table, using the FAS Set. 
All protocol deviations will be listed for all patients in the Randomized Set, including their assignment 
of minor, major, and the date the deviation occurred. 
Protocol deviations linked to COVID-19 will be listed on a separate listing in the Randomized Set.

General Aspects for Statistical Analysis 
 
General Methods 
• SAS Version 9.4 or higher will be used for programming and production. 
• Unless otherwise specified, summaries will be presented for each treatment and overall. 
• Continuous variables will be summarized using the number of observations (n), n missing 
(when applicable), mean, standard deviation (SD), median, minimum, and maximum. 
Categorical variables will be summarized using number of observations (n), n missing (when 
applicable), frequency and percentages of patients. 95% and 99% confidence limits for the 
mean will be calculated based on the t-distribution, where indicated.The denominator will be 
based on the total number of patients in the treatment group or overall, or on the total number 
of subjects with non-missing data, as appropriate. 
• All relevant patient data will be included in listings including assessments of unscheduled visits. 
All patients entered into the database will be included in patient data listings. 
• See Sections 15 and 17 for the definition of planned summary tables and listings. Templates for 
each unique table and patient listing are provided in a separate document. 
 
 
Key Definitions 
 
Baseline Value 
Unless otherwise specified, the baseline value for any variable will be the last value taken prior to the 
start of medication. This includes screening assessment. Unscheduled measurements prior to first 
administration date will be considered in the calculation of baseline values. 
 
Change from Baseline and Percent Change from Baseline at a Post-Treatment Time 
Point  
Change from baseline is defined as the difference between the post-treatment value and the baseline 
value. 
Percent change from baseline is defined as 100* (change from baseline)/ score at baseline.  
 
Time Since Diagnosis of Dry Eye 
Time since diagnosis of dry eye (in months) will be calculated as 12*(date of baseline - date of dry 
eye)/365.25.  
If the date of dry eye is partially missing (month and/or day), then the following rules will be used to 
impute the start date: 
• 
Missing day: replace the missing day by 01.  
• 
Missing month : replace missing month by January  
 
Number of Days on Treatment 
Number of days on treatment is calculated as [(date of last instillation of treatment - date of first 
instillation of treatment) +1]. 
 
Compliance 
Percentage Compliance (%) will be evaluated according to the following formula:

Number of Drops/Day 
 
Drops/day during treatment period is defined as [sum of drops during treatment period / (date of Week 
4 or date of last visit during treatment period – date of baseline +1)]. 
 
Drops/day during follow up period is defined as [sum of drops during follow up period / (date of Week 
16 or date of last visit during follow up period – date of Week 4 + 1)]. 
 
 
 
Missing Data  
 
Missing Data for Efficacy 
For Schirmer test I, Schirmer test II, SANDE, fluorescein staining and TFBUT, the LOCF method will 
be used for imputing missing data in the FAS set at Week 4.  
For missing data at Week 4, the data from the previous visit (Week 2 or early discontinuation visit if 
during treatment period) will be used to estimate the missing value. If a patient has missing data for all 
post baseline visits, baseline will be carried forward (this cannot happen for the primary end-point 
because of the FAS definition). 
Several sensitivity analyses will be performed concerning the primary analysis in case of many missing 
values (decision to be made at the final blind Data Review Meeting, before data base lock).  
The following strategies will be applied: (a) an analysis restricted to the complete cases (only subjects 
having a full data set for the primary outcome will be considered); (b) an analysis of repeated measures 
performed on all subjects having at least one post-baseline efficacy measurement and assuming that 
missing data are distributed as missing at random (see Appendix 1 for the SAS code); (c) an analysis 
considering the worst case method (the worst possible value of the scale is assigned to missing values). 
For IDEEL and EQ-5D-3L questionnaires, missing data will be imputed according to the questionnaire 
manuals. 
 
 
Missing Dates for Adverse Events 
If the adverse event start date is partially or completely missing, then the following rules will be used to 
impute the start date for the purpose of determining treatment emergence status only: 
• 
If the whole start date is missing, then the start date of first drug instillation will be used. 
• 
Missing month: if the AE has occurred the same year as start date of drug instillation, replace 
the missing month of onset by the month of start date of drug instillation.   
If the AE has occurred the subsequent year after the year of start date of drug instillation, 
replace the missing month of onset by January.  
If the AE has occurred the previous year of the year of start date of drug instillation, replace the 
missing month of onset by December.  
• 
Missing day: if the AE has occurred the same month and year as start date of drug instillation 
replace the missing day of onset by the day of start date of drug instillation.

if according to month and year the AE has occurred  after the start date of drug instillation 
replace the missing day of onset by 01.   
• 
if according to month and year the AE has occurred  before the start date of drug instillation 
replace the missing day by the last day of the month.   
 
 
 
Visit Windows 
CRF visits will be used without establishing acceptable visit windows, because the study is short. 
 
Pooling of Centres 
Not applicable. 
 
Subgroups 
The primary, secondary, explorative and safety endpoints will be also summarized within each 
stratification subgroup (absence/presence of Primary Sjögren's Syndrome). 
In order to assess the impact of COVID-19 on primary efficacy endpoint and on safety, subgroup 
analyses will be performed (affected patients versus non affected patients) if 10% or more treated 
subjects are affected by COVID-19 during the study.

Efficacy 
For the purpose of efficacy analysis in this trial, the statistical analysis (both descriptive and 
inferential) will be done on the eligible eye when applicable. 
 
Results from both eyes will be presented in the listings. 
 
Primary and secondary efficacy endpoints will be summarized using the FAS and Per Protocol set. 
Efficacy endpoints will be also summarized for patients with the Primary Sjögren's syndrome and for 
patients without the Primary Sjögren's syndrome . 
 
Efficacy are presented in tables 14.2.1.1.1 to 14.2.2.15.2.3 (see section15) 
 
 
Primary Efficacy Endpoint and Analysis 
The primary efficacy endpoint is the change from baseline in Schirmer test I (without anesthesia) 
versus Week 4. The primary analysis is based on the FAS population. Missing data will be replaced 
by means of the Last Observation Carried Forward (LOCF) method. 
 
The Schirmer test I will be summarized using descriptive statistics for continuous variables by 
treatment and visit. The change from baseline value will also be summarized for all post-baseline 
visits. The same summary analysis will be provided after pooling the treated patients (20 μg/mL BID 
arm and 20 μg/mL TID) together. Comparison (descriptive in nature) of the change from baseline of 
each treatment versus placebo will be performed by means of a t-test at each timepoint.  
 
The primary analysis will be performed by means of an analysis of variance including only treatment 
as main factor followed by pre-planned comparisons from Vehicle and rhNGF dosages according to 
Williams’ procedure.  
The first comparison will compare the rhNGF TID dose to the Placebo using Williams test. 
In case of significant result then the rhNGF BID dose will be compared to the Placebo; if the result is 
not significant then the test will be stopped. 
Description of the Williams’ Test: 
µ0 = Effect of Placebo  
µ1 = Effect of rhNGF BID 
µ2 = Effect of rhNGF TID 
 
Hypotheses: 
H0: µ0 = µ1 = µ2 
H1: µ0< = µ1 ≤ µ2 
 
 
The test develops into two phases: 
* First step 
Starting from the observed means Xi, determine the maximum likelihood estimates Mi (corrected 
mean of group i after amalgamation) under the alternative hypothesis. 
 
If Xi satisfies the inequalities written in H1 then Mi = Xi 
Otherwise pool any adjacent violators into the same value: 
Mi = (ni* Xi + ni+1*Xi+1) / (ni + ni+1) where ni = sample size of group i. 
 
The process is repeated until the means are completely ordered.

Page 24 of 64 
 
* Second step  
Calculate the test statistic given by 
Tk = (Mk – X0)/ s*sqrt(1/ n0 + 1/ nk) 
 
where s = root mean square error and X0 is the observed mean in the placebo group. 
 
The fact that the kth dose level is the minimum effective dose is concluded if Tj > tj,α for all j≥k where 
the tj,α values are the critical values reported by Williams [2]). 
 
The Schirmer test I values will be also listed. 
 
An explorative sensitivity analysis of the primary endpoint will be conducted including in the analysis 
of variance the absence/presence of diagnosis of Primary Sjögren's Syndrome and its interaction with 
treatments as covariates. If the interaction term is statistically significant (at the 0.10 level given its 
explorative nature), the treatment effects within patients with and without Primary Sjögren's Syndrome 
will be provided. 
 
For patients already enrolled in the study, the assignment to a strata will be based on Medical history 
form.  
If “Primary Sjogren” is recorded in the Medical condition of the Medical history form then the patient 
will be assigned to “Presence of Primary Sjogren”; if only “Sjogren” is recorded then the patient will be 
assigned to “Absence of Primary Sjogren”.In all other cases, the patient will be assigned to “Absence 
of Primary Sjogren”. 
 
In order to assess the robustness of results of primary analysis, the Schirmer test I will be also 
evaluated by means of non parametric Fisher’s exact test after appling the following categorization at 
week 4: 
- 
A patient is defined as “Responder” if the Schirmer test I value at week 4 is greater than 10 
mm/5 minutes; 
- 
A patient is defined as “Non responder” if the Schirmer test I value at week 4 is lower or equal 
than 10 mm/5 minutes. 
 
 
Secondary Efficacy Endpoints and Analyses 
The same exploratory sensitivity analysis will be also conducted for SANDE, Schirmer Test II, Corneal 
and Conjunctiva Vital Staining and TFBUT. 
 
Change from baseline in Symptoms questionnaire (SANDE) scores for severity and 
frequency  
The SANDE questionnaire is comprised of 2 questions at each visit:  
 
(1) How often do your eyes feel dry and/or irritated?  
(2) How severe do you feel your symptoms of dryness and/or irritation are?   
 
One measure frequency of symptoms ranges from “0 mm = rarely” to “100 mm = all of the time,” and 
the other measure severity of symptoms ranges from “0 mm = very mild” to “100 mm = very severe”. 
 
The global SANDE score will be calculated by multiplying the frequency score by the severity score 
and obtaining the square root [4]. 
 
Change from baseline at Week 4 will be analyzed using analysis of variance including treatment as 
factor followed by pre-planned comparisons from Vehicle and rhNGF dosages according to Williams’ 
procedure.  
 
Descriptive statistics (actual and change from baseline) of SANDE scores will be presented by 
treatment and visit. Comparison (descriptive in nature) of the change from baseline of each treatment 
versus placebo will be performed by means of a t-test at each timepoint.

Symptoms questionnaire (SANDE) scores will be also listed. 
 
 
Change from Baseline in Schirmer Test II (with Anesthesia) 
The Schirmer test II (with anesthesia) will be summarized using descriptive statistics for continuous 
variables by treatment and visit. The change from baseline value will also be summarized for all post-
baseline visits. Comparison (descriptive in nature) of the change from baseline of each treatment 
versus placebo will be performed by means of a t-test at each timepoint.  
 
The Change from baseline in Schirmer test II at Week 4 will be analyzed in a similar manner as the 
Change from baseline to Week 4 in Schirmer test I. 
 
The Schirmer test II values will be also listed. 
 
 
Change from Baseline in Corneal and Conjunctiva Vital Staining with Fluorescein (NEI 
Scales) 
Corneal staining total score is defined as the sum of scores from 5 corneal areas: Central, Superior, 
Temporal, Nasal, and Inferior. The score for each area ranges from 0 to 3. Thus, the corneal staining 
total score can range from 0 to 15.  
 
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. 
Thus, the conjunctival staining total score can range from 0 to 18.  
 
Corneal and conjunctiva vital staining total score is the sum of corneal staining total score and 
conjunctiva total score. 
 
Descriptive statistics (actual and change from baseline) for Corneal and conjunctiva vital staining total 
score, corneal score and conjunctiva score will be presented by treatment and visit. Comparison 
(descriptive in nature) of the change from baseline of each treatment versus placebo will be 
performed by means of a t-test at each timepoint.  
 
The Change from baseline in Corneal and conjunctiva vital staining total score (NEI scales) at Week 4 
will be analyzed in a similar manner as the Change from baseline to Week 4 in Schirmer test I. 
The Corneal and conjunctiva vital staining score with fluorescein will be listed. 
 
 
Change from Baseline in Tear film break-up time (TFBUT) 
Descriptive statistics (actual and change from baseline) for TFBUT will be presented by treatment and 
visit. Comparison (descriptive in nature) of the change from baseline of each treatment versus 
placebo will be performed by means of a t-test at each timepoint.  
 
Change from baseline in TFBUT at Week 4 will be analyzed in a similar manner as the Change from 
baseline to Week 4 in Schirmer test I. 
TFBUT  values will be listed. 
 
 
Number of Patients who Experienced a Worsening in Symptom Scores (SANDE) and/or 
NEI Score ≥ 50% Assessed at Week 4 
Number and percentage of patients who experienced a worsening in symptom scores (SANDE) 
and/or NEI score ≥ 50% assessed at Week 4 will be summarized by treatment group. 
Difference, between treatment group (Each active dose – Placebo), in the percentage of patients who 
experienced a worsening will be tested using a chi-square test.

The response option “I did not do this activity for reasons other than my dry eyes” has a response 
coded 6 but a scored item value of 5. 
The original response code is the value to be used for data-entry. The item score is used during the 
computation of the Daily Activity Limitations Scale Score. Higher item scores are intended to reflect 
better quality of life (i.e. less limitations on daily activities). 
Only 6 questions (9 (IDLACT1-IDLACT6) are included in the Daily activity Limitations scale score. 
Questions 7, 8 and 9 are excluded.  
If 50% (3) or fewer of the 6 questions used in calculating Daily Activity Limitations score have missing 
item score, then the scale score is calculated by multiplying the mean of the non missing item score 
by 20. If 4 or more of the 6 item scores are missing then the scale score is not calculated and should 
be set at missing. 
Multiplying by 20 transforms the scale score to a 0 to 100 scale, with 0 reflecting the greatest degree 
of limitations on daily activities measurable by the scale and 100 reflecting the greatest freedom from 
limitations on daily activities.

11 questions (IDLEMO1- IDLEMO11) are included in the Emotional Well-Being score. Question 21 
(IDLEMO12) is excluded from calculation. 
If 50% (5) or fewer of the 11 questions used in the calculation of Emotional Well-Being score have 
missing item score, then the scale score is calculated by multiplying the mean of the non missing item 
scores by 25. If 6 or more of the 11 item scores are missing then the scale score is not calculated and 
should be set at missing. 
Multiplying by 25 transforms the scale score to a 0 to 100 scale, with 0 reflecting the worst level of 
emotional well-being measurable by the scale and 100 reflecting the best.

All questions (IDLSYM1 – IDLSYM20)  are included in the Symptom Bother scale score (IDLSYM).  
If 50% (10) or fewer of the 20 questions used in the calculation of Symptom Bother scale score have 
missing item scores, then the scale score is calculated by multiplying the mean of the non missing 
item score by 25. If 11 or more of the 20 item scores are missing then the scale score is not 
calculated and should be set at missing. 
Multiplying by 25 transforms the scale score to a 0 to 100 scale, with 0 reflecting the greatest degree 
of treatment related bother measurable by the scale and 100 reflecting the lowest degree of 
treatment-related bother. 
 
 
 
Changes from baseline in each scale score will be analyzed using an mixed model for repeated 
measures (MMRM). The analyses will include the fixed, categorical effects of treatment (3 levels: 
rhNGF 20 μg/mlTID, rhNGF 20 μg/ml BID and vehicle TID), visit (4 levels: Weeks 4, 8, 12, 16) and 
treatment by visit interaction. Subject will be considered as a random effect.The covariance matrix 
used will be "unstructured". Comparisons versus vehicle TID will be provided using least square 
means at each visit and overall. 
 
IDEEL data will be also listed. 
 
 
 
Patient Global Impression of Change (PGIC) 
Patient Global Impression of Change (PGIC) will be collected at Week 4, Week 8, Week 12 and Week 
16.  
A 7-point scale is used, representing the degree to which the general state of health have changed 
relative to start of the study. On the PGIC, 1 = very much improved and 7 = very much worse. 
A frequency table will summarize the responses for each treatment by visit. To take into account the 
ordinal nature of the response, p-values based on the Wilcoxon rank sum test comparing each rhNGF 
to Placebo will be computed.  
 
PGIC data will be also listed.

EQ-5D-3L 
EQ-5D-3L will be collected at screening, baseline, Week 4, Week 8, Week 12 and Week 16. 
 
The Questionnaire EQ-5D-3L is a 5-dimension instrument assessing quality of life.  
The 5 dimensions are Mobility, Self-Care, Usual Activity, Pain/Discomfort, and Anxiety/Depression. 
Each dimension is scored as 1 = no problem, 2 = some problem, and 3 = extreme Problem. 
No imputation will be done on missing values. 
 
Descriptive summary statistics for the single dimension scores  (“Mobility”, “Self-Care”, “Usual 
Activities”, “Pain/Discomfort” and “Anxiety/Depression”) will be presented by visit and treatment group.  
 
Shift tables comparing results from Baseline to each visit will be presented with percentages based on 
subjects with a non-missing value at Baseline and post-baseline visit. 
 
The patients provide an assessment of their best health state by means of a score between 0 and 100 
(EQ visual analogue scale – VAS).  
The change in VAS score from the baseline visit to the post-baseline visit will be analyzed using an 
mixed 
model for repeated measures (MMRM).  The analyses will include the fixed, categorical effects of 
treatment (3 levels: rhNGF 20 μg/mlTID, rhNGF 20 μg/ml BID and vehicle TID), visit (4 levels: Weeks 
4, 8, 12, 16) and treatment by visit interaction. Subject will be considered as a random effect.The 
covariance matrix used will be "unstructured". Comparisons versus vehicle TID will be provided using 
least square means at each visit and overall. 
 
EQ-5D-3L data will be listed. 
 
 
 
Exploratory Endpoint 
All exploratory endpoints will be summarized using Full Analysis Set. Statistical testing has only a 
descriptive value. 
 
Proportion and frequency of preservative-free artificial tears use (n° drops/day) during 
the treatment period 
The proportions and n° drops/day (see definition in 6.2.6) will be summarized during the treatment 
period, by treatment group. 
 
Proportion and Frequency of Preservative-Free Artificial Tears Use (n° drops/day) During 
the Follow-Up Period 
The proportions and n° drops/day (see definition in 6.2.6) will be summarized during the follow up 
period, by treatment group.  
 
Change from Baseline in Schirmer Test I (Without Anesthesia) Versus Week 2 
Change from baseline in Schirmer test I (without anesthesia) at Week 2 will be analyzed using the 
same analysis used for the primary efficacy end-point.

Change from Baseline in Goblet Cells Density at week 4 
Goblet cells density is measured at baseline, Week 4 and Week 16. 
Change from baseline in goblet cells density at Week 4 will be analyzed using the same analysis used 
for the primary efficacy end-point. 
The goblet cells density will be summarized using descriptive statistics for continuous variables by 
treatment and visit. The change from baseline value will also be summarized for all post-baseline 
visits. 
Goblet cells density will be also listed

Safety 
The population used for safety analyses will be the Safety Set (SS). Safety will be assessed on the 
basis of adverse events (AEs).  
Safety tables are presented in tables 14.1.5.1 and 14.1.5.2 and 14.3.1.1 to 14.3.2.4 ((see section15) 
 
 
Extent of Exposure 
The study drug administration (Day 1 to Week 4) will be captured in the patient diary including the 
administration of preservative-free artificial tears (Day 1 to Week 12). 
The extent of exposure, otherwise referred to as the time from first instillation of study medication to 
last instillation of study medication is defined as:  
Number of days on treatment = date of last instillation of treatment – date of first instillation of 
treatment +1 
 
The data will be summarized by treatment group and presence/absence of primary Sjogren. A listing 
will be also provided.

The assessment of patients’ compliance to the IMP will be made by determining the number of drops 
administered to the eligible eye (see section 6.2.5). 
Gross noncompliance will be defined as compliance for the eligible eye lower than 80% or greater 
than 120% and in case of gross noncompliance the patient will be excluded from the Per Protocol set.  
 
Adverse Events / Adverse Drug Reactions 
Adverse events (AEs) will be coded by SOC and PT, using the Medical Dictionary for Regulatory 
Activities (MedDRA 21.1).  
Treatment-emergent adverse events (TEAEs) are all events occurring or worsening after the first 
dose of the IMP.  
 
TEAEs will be summarized by SOC ,PT, treatment arm and phase (Treatment phase or Follow up). 
Both the number and percentage of patients who experience the event and the number of events will 
be summarised per treatment arm. Percentages will be based on the number of patients in the Safety 
Set.  
 
All tables for TEAEs will be also summarized separately for each strata. 
 
An overall summary of the number and percentage of patients and number of the events with any 
TEAEs, potentially Related TEAEs, Serious TEAEs, Serious Potentially Related TEAEs, TEAEs 
leading to study discontinuation, TEAEs leading to death and TEAE of special interest (AESI)will be 
generated, and presented by treatment arm and phase (Treatment phase or Follow up) 
 
TEAEs will be sorted alphabetically by SOC, and then sorted alphabetically by PTs within SOC.  
 
Separate tables will be presented by severity, and for SAEs, ocular TEAEs, related ocular TEAEs, 
related TEAEs, and TEAEs leading to study discontinuation.

 Changes from Analysis Planned in Protocol 
IDEEL and EQ-5D will be analysed using a mixed model for repeated measures (MMRM) instead of 
analysis of variance as the method seems more appropriate due to the repeated measures. 
Exploratory sensitivity analysis will be also conducted for SANDE, Schirmer Test II, Corneal and 
Conjunctiva Vital Staining and TFBUT instead of only primary efficacy endpoint. 
Overall compliance will not be calculated, as we don’t have in the database the number of unused vials. 
We only have the number of vials not returned to the site whatever the reasons  
Additional analyses have been planned to investigate the impact of COVID-19 pandemic on primary 
endpoint and on patient safety profiles (in case of 10% randomized patients affected). 
Summary statistics on primary endpoint reporting the two treatment doses (20 μg/mL BID arm and 20 
μg/mL TID) pooled versus placebo has been added to see the overall effect of the rhNGF treatment.  
A sensitivity analysis on primary endpoint based on classification of patients in “Responders” and “Non 
Responders” based on the Schirmer Test I at the end of treatment has been added. This analysis will 
assess the robustness of results by considering an exact statistical method (not depending on 
assumption of normality of the data) and based on the status of the patients at the end of treatment.

 Programming Considerations 
All tables, figures, listings (TFLs), and statistical analyses will be generated using SAS for Windows, 
Release 9.4. (SAS Institute Inc., Cary, NC, USA). Computer-generated table, listing and figure output 
will adhere to the following specifications. 
 
General Considerations 
• 
One SAS program can create several outputs, or a separate SAS program will be created for 
each output. 
• 
One output file can contain several outputs. 
• 
Output files will be delivered in Rich Text Format (RTF) that can be manipulated in MSWord. 
• 
Numbering of TFLs will follow ICH E3 guidance. 
 
Table, Listing, and Figure Format 
 
General 
• All TFLs will be produced in landscape format on A4 paper size, unless otherwise specified.  
• All TFLs will be produced using the Courier New font, size 8 which is the smallest acceptable 
point size for the Regulatory Authorities. 
• The data displays for all TFLs will have a minimum blank 1-inch margin on all 4 sides. 
• Headers and footers for figures will be in Courier New font, size 8 which is the smallest 
acceptable point size for the Regulatory Authorities. 
• Legends will be used for all figures with more than 1 variable, group, or item displayed. 
• TFLs will be in black and white (no color), unless otherwise specified. 
• Specialized text styles, such as bolding, italics, borders, shading, and superscripted and 
subscripted text, will not be used in the TFLs, unless otherwise specified. On some occasions, 
superscripts 1, 2, or 3 may be used (see below). 
• Only standard keyboard characters will be used in the TFLs. Special characters, such as non-
printable control characters, printer-specific, or font-specific characters, will not be used. 
Hexadecimal-derived characters will be used, where possible, if they are appropriate to help 
display math symbols (e.g., μ). Certain subscripts and superscripts (e.g., cm2, Cmax) will be 
employed on a case-by-case basis. 
• Mixed case will be used for all titles, footnotes, column headers, and programmer-supplied 
formats, as appropriate. 
 
Headers 
• All output should have the following header at the top left of each page: 
• Dompé farmaceutici S.p.A  
 Protocol NGF0118  
Draft/Final Run <date>

Filing requirements: TMF 
Page 42 of 64 
• All outputs should have Page n of N at bottom right corner of each page. TFLs are internally 
paginated in relation to the total length (i.e., the page number should appear sequentially as 
page n of N, where N is the total number of pages in the table). 
• The date in which output was generated should appear along with the program name as a 
footer on each page. 
 
Display Titles 
• Each TFL is identified by the designation and a numeral. (i.e., Table 14.1.1). ICH E3 numbering 
will be used. A decimal system (x.y and x.y.z) is used to identify TFLs with related contents: for 
example, the set of tables 14.2.1.1.x (i.e. tables 14.2.1.1.1, 14.2.1.1.2, 14.2.1.1.3, …) will be for 
the primary end-point.  The title is centered. The analysis sets are identified on the line 
immediately following the title. The title and table designation are single spaced. A solid line 
spanning the margins will separate the display titles from the column header. 
•  There will be 1 blank line between the last title and the solid line in the column headers. 
Table x.y.z 
First Line of Title 
Second Line of Title if Needed 
ITT Analysis Set 
 
 
Column Headers 
• Column headings are displayed immediately below the solid line described above in initial 
upper-case characters.  
• In the case of efficacy tables, the variable (or characteristic) column will be on the far left 
followed by the treatment group columns and total column (if applicable). P-values may be 
presented under the total column or in separate p-value column (if applicable). Within-treatment 
comparisons may have p-values presented in a row beneath the summary 14.2.statistics for 
that treatment. 
• For numeric variables, “unit” will be included in column or row heading, when appropriate. 
• Analysis set sizes will be presented for each treatment group in the column heading as (N = xx) 
(or in the row headings, if applicable). This is distinct from the ‘n’ used for the descriptive 
statistics representing the number of patients in the analysis set. 
• The order of treatments in the tables will be active treatment first and vehicle, followed by a 
total column (if applicable). 
 
Body of the Data Display 
13.2.5.1. 
General Conventions 
Data in columns of a table or listing are formatted as follows: 
• Alphanumeric values are left-justified. 
• Whole numbers (e.g., counts) are right-justified. 
• Numbers containing fractional portions are decimal aligned.

Page 43 of 64 
 
13.2.5.2. 
Table Conventions 
• Units will be included where available. 
• If the categories of a parameter are ordered, then all categories between the maximum and 
minimum category are presented in the table, even if n = 0 for all treatment groups in a given 
category that is between the minimum and maximum level for that parameter. For example, the 
frequency distribution for symptom severity would appear as: 
Severity 
Rating 
N 
severe 
0 
moderate 
8 
Mild 
3 
 
Where percentages are presented in these tables, zero percentages will not be presented and so 
counts of 0 will be presented as 0 and not as 0 (0%). 
• If the categories are not ordered (e.g., Medical History), then only those categories for which 
there is at least 1 patient represented in 1 or more groups are included, except for reasons for 
discontinuations where all categories will be shown. 
• Unknown or Missing categories are added to each parameter for which information is not 
available for 1 or more patients.  
• Unless otherwise specified, the estimated mean and median for a set of values are printed out 
to 1 more significant digit than the original values, and standard deviations are printed out to 2 
more significant digits than the original values. The minimum and maximum should report the 
same significant digits as the original values. For example, for systolic blood pressure: 
N 
  XX 
Mean 
XXX.X 
Std Dev 
 X.XX 
Median 
XXX.X 
Minimum 
XXX 
Maximum 
XXX 
 
• P-values are reported in the format: “0.xxx”, where xxx is the value rounded to 3 decimal 
places.  
• Percentage values are printed to one decimal place, in parentheses with no spaces, one space 
after the count (e.g., 7 (12.8%), 13 (5.4%)). Unless otherwise noted, for all percentages, the 
number of patients in the analysis set for the treatment group who have an observation will be 
the denominator. Percentages after zero counts should not be displayed and percentages 
equating to 100% are presented as 100%, without decimal places.  
• As general rule, the percentage of patients is calculated as a proportion of the number of 
patients assessed in the relevant treatment group (or overall) for the analysis set presented.  
• Where a category with a subheading (such as system organ class) has to be split over more 
than one page, the subheading will be followed by “(cont)” at the top of each subsequent page.

Page 44 of 64 
The overall summary statistics for the subheading should only be output on the first relevant 
page. 
13.2.5.3. 
Listing Conventions 
• Listings will be sorted for presentation in order of: patient number, treatment groups, 
visit/collection day and visit/collection time. 
• Dates are printed in SAS DATE9.format (“ddMMMyyyy”: 01JUL2000). Missing portions of dates 
are represented on patient listings as dashes (--JUL2000). 
• All observed time values are to be presented using a 24-hour clock HH:MM or HH:MM:SS 
format (e.g., 11:26:45, or 11:26). Time will only be reported if it was measured as part of the 
study. 
• Units will be included where available.

 Quality Control 
SAS programs are developed to produce output such as analysis data sets, summary tables, data 
listings, figures or statistical analyses.  
Programs for the production of SDTM domains, ADaM/analysis datasets and TFLs will be double-
programmed. For datasets, tables and listings, the production programming results and validation 
programming results will be compared electronically. 
A more complete overview of the development of programs is detailed in Syneos Health SOP 
Developing Statistical Programs (3907). 
Syneos Health SOPs Developing Statistical Programming Specifications (3906), Developing 
Statistical Programs (3907) and Conducting the Transfer of Biostatistical Deliverables (3908) describe 
the quality control procedures that are performed for all SAS programs and outputs. Quality control is 
defined here as the operational techniques and activities undertaken to verify that the SAS programs 
produce the output by checking for their logic, efficiency and commenting and by reviewingf the 
produced output.

2) Sample Code for Efficacy Analysis : Schirmer test I in case of presence of many missing data 
 
For RMM, if SAS mixed model is used, the sample SAS codes will be like the following: 
 
PROC MIXED DATA=SCHIRMERI;  
CLASS usubjid TRT01P visit;  
MODEL chg = TRT01P TRT01P * visit /ddfm=kr;  
repeated visit / sub = usubjid type = un;  
lsmeans TRT01P / cl diff at time = Week4;  
  
3) Sample Code for Exploratory sensitivity Efficacy Analysis : Schirmer test I  
 
 
PROC MIXED DATA=SCHIRMERI;  
CLASS STRATA TRT01P ;  
MODEL chg = TRT01P STRATA STRATA*TRT01P /solution; 
lsmeans STRATA*TRT01P / pdiff cl  at time=Week4; 
 
 
4) Sample Code for Efficacy Analysis : IDEEL and EQ-5D-3L 
 
PROC MIXED DATA=IDEEL;  
CLASS usubjid TRT01P visit;  
MODEL chg = TRT01P  visit TRT01P * visit /ddfm=kr;  
repeated visit / sub = usubjid type = un;  
lsmeans TRT01P*visit / cl pdiff; 
lsmeans TRT01P / cl pdiff;
