o To assess the safety of PRO-231 ophthalmic solution applied to the ocular surface, 
in healthy volunteers, versus VIGAMOXI,® by: 
▪ 
To compare the incidence of adverse events (AEs), unexpected, related to 
interventions. 
▪ 
Incidence of conjunctival hyperemia and/or chemosis between 
interventions. 
▪ 
Changes in best-corrected visual acuity (MCVA) assessed with the Snellen 
chart between interventions. 
▪ 
Changes in ocular surface integrity using fluorescein staining, using the 
Oxford scale between interventions.  
o To evaluate the tolerability of PRO-231 ophthalmic solution applied to the ocular 
surface, in healthy volunteers, versus VIGAMOXI,® by:  
▪ 
Changes in Eye Comfort Index (JI) score between interventions. 
 
• 
Side: 
o To assess the safety of PRO-231 ophthalmic solution applied to the ocular surface, 
in healthy volunteers, versus VIGAMOXI,® by: 
▪ 
Incidence of expected and intervention-related AEs (excluding 
conjunctival hyperemia and/or chemosis). 
o To evaluate the tolerability of PRO-231 ophthalmic solution applied to the ocular 
surface, in healthy volunteers, versus VIGAMOXI,® by:  
▪ 
Presence of ocular symptoms (burning, foreign body sensation, pruritus 
and tearing) between interventions. 
 
Hypothesis: 
H0= PRO-231 ophthalmic solution has a safety and tolerability profile similar to that of VIGAMOXI® 
in clinically healthy subjects. 
𝐻0: 𝑆𝑇𝐴= 𝑆𝑇𝐵 𝑜 𝑆𝑇𝐴−𝑆𝑇𝐵= 0 
 
H1= PRO-231 ophthalmic solution does not have a similar safety and tolerability profile as

Statistical methodology 
The analysis of the data collected in the study will be carried out by means of specialized statistical 
software (SPSS available version or R software). The data will be expressed with measures of 
central tendency: mean, standard deviation and/or ranges for quantitative variables, and 
frequencies and/or percentages for qualitative variables. The Shapiro-Wilk test (S-W) will be used 
to determine if the distribution is normal in the data obtained in each study group (p>0.05). If the 
normality in the distribution of the data is verified, to rule out differences between groups, the 
Student's t-statistic will be used for independent groups, while intragroup differences will be 
analyzed with the Student's t-test for repeated measures. In case of p<0.05 in S-W, the statistical 
analysis to rule out differences between groups will be performed by means of the Mann-Whitney 
U test for quantitative variables, while intragroup differences will be performed by Wilcoxon's rank 
test. The difference between the qualitative variables will be analyzed by means of the X2 statistic 
(Chi-squared) or Fisher's exact (for expected values less than 5). Dichotomous variables will be 
analyzed by the McNemar test when applicable. An alpha (α) ≤0.05 will be considered as statistical 
significance, in addition to this, the 95% CI will be calculated for these differences. For primary 
outcome variables, H0 will be rejected, when p≤ 0.05 and the 95% CI does not include zero.

2. Introduction and background 
2.1 Theoretical framework 
Humans are exposed to a variety of microorganisms, including bacteria, viruses, and fungi. In most 
cases, these microorganisms do not cause infection thanks to the external barriers (skin and mucous 
membranes) that protect us from their invasion, and the immune system. However, some 
microorganisms can directly invade these external barriers or be introduced into the body through 
surgical or traumatic wounds; Additionally, the patient's immune system may be compromised, 
allowing microorganisms, which do not normally cause any problems, to generate an infection. [1] 
Various compounds have been used to help the immune system fight pathogenic microorganisms. 
An important property of anti-infective drugs is their selective toxicity, eliminating microorganisms 
while causing minimal or no adverse reactions to the host. [1] 
These drugs are not usually active against all species of microorganisms in the same category; The 
species against which the drug shows intrinsic activity is called Spectrum of activity of the drug. 
Narrow-spectrum drugs are only effective against a few species of microorganisms, while broad-
spectrum drugs have activity against a wide variety of species. At the same time, microorganisms can 
develop resistance mechanisms against drugs to which they were originally susceptible, limiting the 
effectiveness of anti-infective drugs. [1] 
Bacteria are the largest contributor to eye infections in the world and can affect different eye 
structures causing conjunctivitis, keratitis, endophthalmitis, blepharitis, orbital cellulitis and 
dacryocystitis.  [2, 3] 
Bacterial conjunctivitis is one of the most common eye infections and is estimated to account for up 
to 1% of consultations at the first level of care. It is characterized by eye discomfort, conjunctival 
injection, and mucopurulent discharge, and has a significant economic and social impact, as a result 
of disruption of the patient's normal activities, as well as absenteeism from work and/or school. It is 
usually self-limiting (duration of 1 to 2 weeks); however, empirical treatment with broad-spectrum 
anti-infective drugs is recommended to shorten the course of the disease, improve patient comfort, 
decrease transmissibility, promote early return to work or school, and reduce the risk of serious 
complications that may compromise vision [1, 2, 3, 4, 5, 6, 7] 
The pathogens most commonly implicated in bacterial conjunctivitis include strains of Staphylococcus 
aureus, Streptococcus pneumonie, Streptococcus viridians, Haemophilus influenzae, Serratia 
marcescens and Pseudomona aeruginosa. [8, 9]
Although broad-spectrum topical antibiotics are usually used empirically, several factors need to be 
considered when selecting a treatment, such as how quickly it kills the pathogen causing the 
infection, how well it penetrates eye tissues, and the potential impact on the development of 
bacterial resistance. [9]

Moxifloxacin is a broad-spectrum antimicrobial that belongs to the fourth generation 
fluoroquinolones and thanks to its 8-methoxy group, it has improved activity against strains of 
Streptococcus and Staphylococcus, as well as moderate to excellent activity against gram-negative 
organisms that cause ocular pathologies. [6] 
Moxifloxacin is a dose-dependent bactericide. Like the other fluoroquinolones, it interferes with the 
bacterial life cycle by binding to DNA gyrase (topoisomerase II) and topoisomerase IV. Both are 
essential enzymes for the replication, translation, repair, and recombination of bacterial 
deoxyribonucleic acid (DNA).  Human cells lack these enzymes, so they are not affected by 
fluoroquinolones.[6, 8, 9, 10] [1, 8] 
The antimicrobial activity or spectrum of fluoroquinolones will depend on their class, due to the 
variation in affinity and binding strength to topoisomerases, as well as to the bacterial species. [10] 
They are generally well-tolerated drugs with a low incidence of adverse reactions after systemic 
administration. When they occur, these reactions are usually mild and reversible, the most common 
being: gastrointestinal (nausea, vomiting and diarrhea), dermatological (rash, urticaria, pruritus) and 
central nervous system (headache). However, they have also been associated with serious adverse 
events, including Clostridium difficile, prolongation of the QT interval, tendinitis, dysglycemia, liver 
toxicity, phototoxicity, acute renal failure and seizures. [1, 8, 11, 12] 
The frequency of adverse events with topical fluoroquinolone administration is low; The most 
frequent ocular adverse reactions reported after the application of the 0.5% moxifloxacin ophthalmic 
solution are: decreased visual acuity, dry eye, keratitis, eye discomfort, ocular hyperemia, eye pain, 
pruritus, subconjunctival hemorrhage, tearing and burning. The most frequent non-ocular adverse 
events reported are: dysgeusia, fever, cough, otitis media, pharyngitis, rash and rhinitis. . [1][13, 14] 
The following adverse reactions have been reported during clinical studies with Moxifloxacin 5 mg/mL 
ophthalmic solution and are classified according to the following criteria: very common, occurring in 
1 or more in 10 patients (≥1/10); common, occurring in 1 or more in 100 patients (≥1/100 to <1/10); 
rare, occur in 1 or more in 1,000 patients (≥1/1,000 to <1/100); rare, occurring in 1 or more in 10,000 
patients (≥1/10,000 to <1/1,000); very rare, there is less than one case in every 10,000 patients 
(<1/10,000); or unknown frequency (a number cannot be estimated from the available data). Adverse 
reactions are ordered by organ or system affected, from the most severe to the mildest: [15, 16, 17]

Available ophthalmic fluoroquinolones are indicated for the treatment of bacterial conjunctivitis and 
keratitis, with a treatment regimen of one drop three times daily for 7 days (the total duration of 
therapy will depend on the severity of the clinical picture and the course of the infection).  In addition, 
they have been used off-label as prophylaxis in surgical procedures and ocular trauma to prevent 
endophthalmitis. However, because new molecules such as gatifloxacin and moxifloxacin have a 
higher spectrum and lower resistance, they should be reserved for the treatment of more severe eye 
infections.[8, 9, 15, 16] [17, 18] [17, 19] 
There is no antimicrobial that provides ideal coverage for all pathogens at any site of infection. 
However, moxifloxacin 0.5% ophthalmic solution is a unique, preservative-free antibiotic (thanks to

its concentration it does not require the addition of preservatives to the formula), which offers broad-
spectrum activity, and a moderate to high clinical success rate against common ocular pathogens. In 
addition to this, thanks to its concentration and its high penetrance to the ocular tissues, it allows a 
dosing regimen at infrequent intervals, simplifying its administration and making it more convenient 
for patients. [6, 7, 9, 10]
 
2.2 Background on the investigation 
2.2.1 From the research question 
Is the application of PRO-231 ophthalmic solution safe and tolerable in clinically healthy subjects? 
The importance of the question that precedes this paragraph is that Laboratorios Sophia S.A. de C.V. 
does not have clinical studies with products identical to the PRO-231 solution, although there are 
with similar products (different fluoroquinolones and excipients).  
 
2.3 Problem statement 
Bacterial conjunctivitis is one of the most common eye infections and it is estimated that it represents 
up to 1% of consultations at the first level of care, generating a significant economic and social impact, 
as a result of the interruption of the patient's normal activities, as well as absenteeism from work 
and/or school.  Although it is usually a self-limiting condition, with an average duration of 1 to 2 
weeks, empirical treatment with broad-spectrum anti-infective drugs is recommended to shorten the 
course of the disease, improve patient comfort, decrease transmissibility, promote early return to 
work or school, and reduce the risk of serious complications that may compromise vision [9][1, 2, 3, 
4, 5, 6, 7] 
Fluoroquinolones are antibiotics whose usefulness in the area of ophthalmology has already been 
proven, as they have been used for decades as a treatment and/or prophylaxis for eye infections. Its 
effectiveness and safety have given this family of drugs a significant place within the therapeutic 
options of today's ophthalmologist; however, despite being generally well-tolerated drugs with low 
toxicity, it was decided to compare PRO-231 with VIGAMOXI,® the topical formulation of moxifloxacin 
0.5% currently marketed in our country, to verify that its safety and toxicity profile is equal to the 
latter. 
 
2.4 Rationale for the study 
Although eye infections can be considered minor infections, in some cases, they can become 
complicated and leave irreversible sequelae that can compromise the patient's vision. For this reason 
it is important to prescribe topical antibiotics for the treatment of eye infections, or as prophylaxis in 
surgical procedures and eye trauma. An important property of anti-infective drugs is their selective

toxicity, eliminating microorganisms while causing minimal or no adverse reactions to the host. [17, 
18] [1] 
Moxifloxacin hydrochloride, the active ingredient in PRO-231 ophthalmic solution, is a fourth-
generation fluoroquinolone, which has already been approved for use in the treatment of bacterial 
conjunctivitis and keratitis caused by susceptible strains; and it is already marketed by international 
ophthalmic product laboratories. It has the advantage of being preservative-free, and in addition, 
offers broad-spectrum activity, and a moderate to high clinical success rate against common ocular 
pathogens. In addition to this, thanks to its concentration and its high penetrance to the ocular 
tissues, it allows a dosing regimen at infrequent intervals, simplifying its administration and making 
it more convenient for patients. [6, 7, 9, 10] 
In our country, this antibiotic formulation is marketed and approved under the name VIGAMOXI® 
(Alcon Laboratories, Inc. Fort Worth, Texas, USA) for the treatment of bacterial conjunctivitis. Clinical 
studies are required to evaluate that the safety and tolerability of PRO-231, prepared by Laboratorios 
Sophia S.A. de C.V., is comparable to that of VIGAMOXI,® and which are the basis of future clinical 
studies that prove its efficacy. The current commitment of Laboratorios Sophia, S.A. de C.V. is to 
generate its own information for its products that serves for the pertinent regulatory procedures, 
and as a scientific basis for their commercialization.

3.2 Study hypothesis 
 
H0: PRO-231 ophthalmic solution has a similar safety and tolerability profile as VIGAMOXI® in clinically 
healthy subjects. 
 
𝐻0: 𝑆𝑇𝐴= 𝑆𝑇𝐵 𝑜 𝑆𝑇𝐴−𝑆𝑇𝐵= 0 
 
 
H1: PRO-231 ophthalmic solution does not have a similar safety and tolerability profile  as VIGAMOXI® 
in clinically healthy subjects.  
 
𝐻1:𝑆𝑇𝐴≠𝑆𝑇𝐵 𝑜 𝑆𝑇𝐴−𝑆𝑇𝐵≠0 
 
Operational definition of similarity: To reject H0, the p-value in the primary variables must be ≤ 
0.05 and the 95% CI of this difference must not include zero. Both conditions for hypothesis testing 
(p-value and 95% CI) must be met, otherwise the result will be interpreted as "absence of evidence", 
not as "evidence of absence".

4. Study design 
4.1 Study Overview 
Phase I clinical study, controlled, comparative, parallel-group, single-blind, single-center. 
 
4.2 Rationale for the study design  
The design of the study (clinical trial) is considered the highest standard of data quality when seeking 
to explore the effect of an intervention. The drug development phase (phase I) corresponds to the 
objective of the study, which is to evaluate safety and tolerability, so the intervention time is short 
and the sample size required is smaller than that of an efficacy clinical trial.  
Although this is a comparative study with two intervention groups, only the principal investigator and 
the person responsible for the statistical analysis will be blinded, because the primary packaging of 
the comparator cannot be modified to resemble the product under investigation. Despite this, the 
secondary packaging for the products will be the same and the researcher will not know the 
allocation. 
 
4.3 Expected duration of the study  
The total duration of the study, from the first subject's first visit to the preparation of the final report, 
is estimated to be 5 to 6 months. 
 
4.4 Duration of the subject in the study/treatment  
The approximate duration of each subject in the study is up to 13 days.

up, until the necessary sample size is completed. 
 
5.3 Counting failures 
A screening failure is defined as those participants who agree to participate in the study, giving their 
consent, but who are not assigned to the treatment group, i.e., do not enter the study. It is necessary 
to report at least the following information on counting failures:   
- 
Demographics. 
- 
Details of the failure to count (specify whether it is due to eligibility criteria, which one, or 
some other reason for the failure).  
- 
Presence of serious adverse events during the count.  
This is necessary to comply with the CONSORT (Consolidated Standards of Reporting Trials) guidelines 
for the publication of results or to respond to possible questions from regulatory authorities.

5.4 Recruitment and retention strategies  
The duration of the subject's participation in the study is approximately 13 days, during which time 
the subject will be required to attend three visits in total and will be given a safety call, which 
corresponds to the baseline visits, visit 1, final visit and safety call. Strategies to improve subject 
retention include, but are not limited to:  
• 
Clearly inform the objectives of the study. 
• 
Make calls or send text messages to remind you of appointments or activities to do. 
• 
Provide a printed calendar and an identification card in order to remember 
appointments and activities that will be carried out, in addition to the estimated time of 
their duration.  
• 
Systematic organization of the study procedures, so that the subject does not last longer 
than necessary in his visit.  
• 
Minimize subject wait times.  
All materials to be delivered to the subject or recruitment strategies implemented by the center will 
be submitted for approval by the corresponding committees.  
 
5.5 Procedure in case of loss of follow-up  
For this protocol, loss of follow-up is defined as those subjects who were assigned the PI, who at 
some point were active subjects of the study, but their final evaluation could not be completed.  
In the event that the subject does not terminate their participation due to withdrawal of consent or 
major deviation, the last visit, in which their withdrawal was determined, will be considered their 
final visit. Subjects who are removed due to the presence of AEs will continue with the follow-up that 
is defined until the closure of their AE.  
In cases where the participating subject does not attend their appointment, the research center must 
make a call to find out the reason and will try to make a new appointment within the established 
window period or an unscheduled appointment. In the event that it is not possible to make an 
appointment, the subject will be considered as loss of follow-up and will be asked about the presence 
of adverse events and the reason for leaving the study, as minimum data.  
A loss of follow-up <20% is considered not to be a problem for the validity of the results obtained.

5.6 Identification of the subject  
Study subjects will be identified by a number and the initials of their name.  
The initials of the study subject will be obtained starting with the first letter of the name, followed 
by the first letter of the first surname and the first letter of the second surname, obtaining a 
maximum of three letters, in case the person has two names or compound surname, the first letter 
will always be used.  
Example:  
 
To. Arieh Daniel Mercado Carrizalez   
 
B. Juan De la Torre Orozco  
 
to. Initials: AMC     
 
 
 
b. Initials: JDO  
In the counting stage, the participant number will be assigned consecutively, using 3 consecutive 
digits.   
Once the subject has been selected, they will be assigned a number with which they will be identified 
throughout the study. This code will be made up of eight numbers in the following order from left to 
right:   
• 
three digits of the molecule under study according to the name by the sponsor.    
• 
Two digits corresponding to the research centre number.   
• 
three digits of the number following their inclusion assigned in the research centre.

The delivery will be made by means of a courier service contracted by the sponsor, expressly selected 
for this purpose, to the address of the research center according to the study plan. 
The reception will be carried out by the assigned personnel of the research team. You will need to 
check that the primary packaging (box) is in good condition. In the event that you show alterations 
or defects in its integrity that in your judgment could have damaged the content, you must report it 
to the sponsor. If the package does not show significant defects, it will proceed to open it.

   Page  35 de 90 
Inside the shipment you must locate the acknowledgment document and the temperature meter 
(data logger). You must check that the temperature recorded complies with what is specified for 
transport and safekeeping. It will verify the content (PI) with what is reported in the document. In 
case the document corresponds to the content, you will sign the receipt and send it to the sponsor. 
Otherwise, it will notify the sponsor. 
Storage and safeguarding is the responsibility of the research center. The medication must be stored 
in a secure area with restricted access. 
The storage temperature should be 2° to 25°C. 
From its receipt at the center and until there is no stock of PI stored, the research center has the 
obligation to review the storage conditions of the PI on a daily basis and manually record, in the 
designated format, the temperature set by the data logger (current, minimum and maximum 
temperature). Such data will be reviewed by the clinical monitor during their monitoring visits 
according to the records stored in the data logger's memory. 
In the event of loss of material, it must be documented in the logbook of inputs and outputs along 
with a clear description of the mechanism by which the loss occurred. 
Upon completion of the protocol, all study material will be retrieved by the sponsor as part of the 
closing visit. The final delivery of material will be made by the principal investigator or the person 
designated by him to deliver material at the end of the study. 
The sponsor reserves the right to initiate civil and criminal action against the principal investigator in 
the event of a lack of undocumented material at the conclusion of the study. 
6.3 Concomitant treatments and medications (permitted and prohibited)  
Any medication that is used, in addition to appearing in the clinical note, must be registered in the 
concomitant medication section of the eCRF ( electronic Case Report Form). 
6.3.1 Permitted Medications 
- 
Ophthalmic:  
All permitted medications applied via ophthalmic medication during the study must wait a minimum 
period of 10 minutes from the last application of the treatments under study or reference. The above 
in order to avoid the interaction of treatments in the tear film, based on the flow index and 
physiological tear volume.  [22]

In case participants of childbearing potential decide to use a hormonal contraceptive method, 
the following will be allowed:  
o Oral contraceptives. 
o Subdermal implant. 
o Parenteral injection. 
o HORMONAL DIU. 
 
6.3.2 Prohibited medicines:  
- 
Any ophthalmic or systemic medications that are not on the list of allowed medications. 
 
6.4 Procedure for monitoring and measuring adherence  
For more than four decades, numerous investigations have been conducted on the appropriate way 
to measure and quantify medication adherence, however, none has reached a consensus to stand as 
the gold standard, both in cross-sectional and longitudinal studies. [23, 24, 25, 26, 27, 28, 29, 30] 
There are different procedures to measure adherence to pharmacological interventions. The most 
common procedure includes self-reports, which include: interviews with the subject, questionnaires 
and self-monitoring diaries. Its strengths are speed, flexibility, low cost and ease of implementation; 
They have a high degree of specificity for non-adherence, however, the sensitivity and reliability for 
adherence is low. [30, 31] 
The biochemical measurement of the drug, or its metabolite, is one of the methods that best confirms 
the use of the drug. However, in addition to raising costs and being impractical, it is of little use in the 
context of ophthalmic applications, since concentrations at the peripheral level could be 
undetectable; and samples of other tissues involve more invasive methods that would not be 
advisable. [30] 
There is no standardized parameter to define adequate adherence, it must be defined and delineated 
by the objectives of the particular research.  [30] 
For this study, a minimum adherence of 80% (per subject's diary) will be considered to be necessary 
to meet the objectives of the research; In turn, the information in the diary will be corroborated with 
the final weight of the research product with respect to its initial weight. Therefore, subjects with 
adherence of less than 80% will not be considered for the study.

6.5 Strategies to improve adherence  
1. The PI will sensitize the subject to the importance, in order to achieve the objectives of the 
study, of the correct application of the concomitant treatment.  
2. Direct questioning by the PI about the application of the concomitant treatment. 
3. Delivery of a printed calendar specifying the date of the visit and its activities. 
If deemed necessary, text messages may be sent as reminders. The content of these messages must 
be previously approved by the Research Ethics Committee (ERC).

7. Study methods and procedures  
7.1 Research centre  
This study will be carried out in a research center previously evaluated by the sponsor. The center 
will be an institution or establishment where health research is carried out that complies with current 
regulations.  
The research center will be responsible for forming a multidisciplinary research team to execute the 
clinical study according to the protocol. It is their prerogative to design the organization and select 
the personnel who will perform the functions. However, it is necessary for the sponsor that the PI 
and sub-investigator be ophthalmology specialists.  
Any person who is designated, under the responsibility of the PI, a part of the study monitoring (sub-
investigator, nurse, etc.) or a specific function of participation in the study (pharmacist, 
administrative assistant, study coordinator, etc.) must appear in the "Delegation of Responsibilities". 
The competence and training of any person who has direct participation in the activities of the study 
must be verified prior to the performance of any activity related to the protocol. The above must be 
recorded and the documents that constitute evidence of this competence and/or training must be 
kept in the master file of the study. The competence and training of the personnel who have 
functions in the study, both at the central level and in the study center, is the responsibility of the 
principal investigator.  [32] 
The sponsor must ensure that all study site personnel participating in the study are adequately 
trained on the study (research protocol, investigator's manual, amendments, standard operating 
procedures, etc.) and on the Good Clinical Practices of the ICH (International Council on 
Harmonization) International Council for Harmonisation), before the start of their participation in it. 
Training must be recorded in writing and those records must be filed in the master record of the 
study. [32] 
 
7.2 Clinical Study Registration  
This clinical study will be registered by the sponsor in public clinical trial registries before its start 
(inclusion of the first subject): National Registry of Clinical Trials (RNEC) of the Federal Commission 
for the Protection against Sanitary Risks (COFEPRIS) and in a primary registry platform of the World 
Health Organization (WHO). WHO primary registries meet specific criteria for content, quality and 
validity, accessibility, unique identification, technical capacity, and administration. WHO Primary 
Registries meet the requirements of the International Committee of Medical Journal Editors (ICMJE).

7.3 Assignment of treatment 
The assignment/randomization of the treatment will be carried out centrally using a validated 
electronic system from an external provider, previously evaluated and authorized by Laboratorios 
Sophia S.A. de C.V. There are two treatment groups. Participants will be randomized in a 1:1 ratio to 
treatment with PRO-231 or VIGAMOXI.® Having the same probability of being assigned to one or the 
other treatment. After signing the FCI, the subject will receive a participant number with which all 
their information will be encrypted pseudonymity during collection and completely anonymized 
during analysis. The generation will be carried out by a third party, authorized by Laboratorios Sophia, 
S.A. de C.V., through its electronic system, through a list of random numbers generated by software 
(SAS Institute Inc, Cary, NC, USA). The information pertaining to this third party will be on file. Only 
the principal investigator and the person responsible for the statistical analysis will be blinded, 
because the primary packaging of the comparator cannot be modified to resemble the product under 
investigation. Despite this, the secondary packaging for the products will be the same and the 
researcher will not know the allocation. IP will be identified by means of labels in accordance with 
current and applicable regulations, which must contain at least: 
- 
Sponsor's name, address, and phone number. 
- 
Dosage form and route of administration. 
- 
Number of doses. 
- 
Batch number. 
- 
Legend "Exclusively for clinical studies".

7.4.4 Description of the variables, methods and scales for their measurement 
For clinical purposes, ophthalmological evaluations will be carried out in both eyes, and their record 
will be recorded in the clinical file. However, in order to obtain results and comply with the 
assumption of independence within the variables, only the examinations and qualifications of the 
right eye will be recorded in the eCRF when appropriate. Next, the description of the variables is 
made, which are not in order of execution.

7.4.4.1 Conjunctival hyperemia  
It is defined as the simplest reaction of the conjunctiva to a stimulus, with a red appearance 
secondary to vasodilation of the conjunctival vessels of variable intensity. It will be graduated using 
the Efron scale. See annex  [38]16.2. Efron Scale for Conjunctival Hyperemia 
The PI will record in the file and the eCRF the grade, in grades (Grade 0 = normal, grade 1 = traces, 
grade 2 = mild, grade 3 = moderate, grade 4 = severe), granted for conjunctival hyperemia OD and 
OS respectively. 
Management as AE: An adverse event will be considered when the grade is greater than or equal to 
grade 3 (moderate).  
7.4.4.2 Chemosis 
It is defined as conjunctival edema, the result of an inflammatory reaction. It is qualified as present 
or absent. The evaluator will use a narrow beam of light at 60° and will measure whether the 
conjunctiva separates from the sclera by ≥ 1/3 of the total eyelid opening or if it exceeds the gray 
line.  [39] 
The PI will record in the file and the eCRF if the chemosis is absent or present. 
Management as AE: An adverse event will be considered when present. 
7.4.4.3 Ocular symptomatology 
The subject will be questioned directly about the presence in general (since the last visit) of the 
following symptoms: burning, foreign body sensation, pruritus, tearing. 
7.4.4.3.1 Ardor 
Feeling of irritation or stinging in the eyes. [37] 
7.4.4.3.2 Foreign Body Sensation 
Feeling of sand inside the eye. [36] 
7.4.4.3.3 Pruritus 
It is an itching or tickling sensation that causes the need to rub or scratch the eye. [34] 
7.4.4.3.4 Lagrimeo  
Excessive tear production or flow. [35, 36] 
The subject will respond only if the symptom is absent or present  
These symptoms will be analyzed as one of the variables of the study and will not be considered an 
adverse event.

7.4.4.4 Best-corrected visual acuity 
Visual acuity (VA) is a test of visual function. Visual spatial acuity is the ability to distinguish separate 
elements of an object and identify them as a whole. It is quantified as the minimum angle of 
separation (located at the nodal point of the eye) between two objects that allows them to be 
perceived as separate objects.  
Snellen's notation is described as the distance at which the test is performed, divided by the distance 
at which the letter is vertically equivalent to 5 arc minutes. Thus, at 6 meters a letter 6/6 (20/20) is 
equivalent to 5 minutes of arc, a letter 6/12 (20/40) is equivalent to 10 minutes, and a letter 6/60 
(20/200) is equivalent to 50 minutes. The Snellen fraction can also be expressed as a decimal place 
(i.e., 20/20 = 1 and 20/40 = 0.5). [40] 
VA will be evaluated at baseline, without refractive correction with the Snellen chart (see annex 16.1 
Cartilla de Snellen). It will be located in a place with adequate lighting (natural or artificial) and at a 
distance of 3m from the subject to be evaluated. Visual acuity of the right eye (OD) will be taken 
initially, asking the subject to hold both eyes open and using an occluder to cover the contralateral 
eye; the subject will read aloud the lines that the evaluator points out, the line of smaller letters that 
he can see will be noted by the evaluator in fraction as the AV of OD in the clinical record and the 
eCRF, then the same evaluation will be performed in the left eye and its record only in the clinical 
file. 
Next, the subject's best refractive correction (obtained by autokeratorrefractometer and subjective 
tests) will be evaluated and the examination will be repeated using the refraction obtained. This 
result will be reported as best-corrected visual acuity. 
Both data (AV and AVMC) will be reported for statistical purposes in logarithmic figures (LogMAR) in 
the eCRF.  
A fraction conversion table is attached to LogMAR. (see annex 16.5 Fraction to LogMAR conversion 
table. ) 
Management as AE: A decrease in 2 or more lines of sight in BCVA compared to that obtained at 
baseline will be considered an adverse event. 
7.4.4.5 Ocular surface staining  
Fluorescein (TF) staining: A drop of topical anesthetic will be instilled in the bottom of the conjunctival 
sac, then a second drop will be applied to the tip of the fluorescein strip, allowing it to sit on the strip 
for 5 seconds to elute the dye, shaking off the excess at the end. A small contact of the strip is made 
with the conjunctiva at the fundus of the temporal sac, while the subject looks upwards, without 
damaging the conjunctiva. Between 4 and 8 minutes after the instillation of the staining, the 
assessment of the fluorescein stain in the cornea is carried out, with the slit lamp with a cobalt blue 
filter. It will be graded according to the Oxford Scale.  See attachment [41, 42]16.3 Oxford scale

The PI will record in the file and the eCRF the grade, in grades (Grade 0 = Absent, grade I = Minimal, 
grade II = Mild, grade III = Moderate, grade IV = Marked, grade V = Severe), granted for the corneal 
staining of OD and OS respectively. 
Management as AE: An adverse event will be considered when the rating is greater than or equal to 
grade III (moderate). 
7.4.4.6 Adverse events 
As described in the 8. Evaluation and management of adverse events An adverse event is defined as 
any unfavorable medical occurrence in a subject to whom an investigational product is administered, 
regardless of causal attribution.  
Adverse event management shall be carried out as described in section 8. Evaluation and 
management of adverse events and incidents.  
The Principal Investigator will record in the corresponding section of the eCRF the adverse events 
that the study subjects may present in addition to referring them in the clinical record.  
For an adequate evaluation of adverse events, in addition to directed questioning, it is necessary to 
perform a comprehensive ophthalmological evaluation at each visit, which consists of: 
ophthalmological examination of the eyelids and adnexa; anterior and posterior segment that is 
performed in a routine ophthalmological check-up, whose procedures are not specifically included 
in the study variables. Posterior pole evaluation can be with direct or indirect ophthalmoscopy, with 
or without pharmacological mydriasis, at the discretion of the PI. An assessment of the fundus will 
be carried out in search of abnormalities that alter the result of the study. IOP will be measured in 
this evaluation, with the Goldmann tonometer, it should be measured after the evaluation of stains. 
The result of the assessment will be recorded in the clinical file. In the eCRF, only findings that are 
considered so by the Principal Investigator will be reported as an adverse event.  
The ocular adverse events that can occur with PRO-231, according to what is reported in the 
literature, are: ocular burning, dysgeusia after instillation, foreign body sensation, ocular pruritus, 
conjunctival hyperemia, chemosis, photophobia and whitish corneal precipitates.  The frequency of 
systemic adverse events with ophthalmic fluoroquinolone administration is low.[1, 13] [1] 
7.4.4.7 Eye Comfort Index 
It is a questionnaire designed to measure ocular surface irritation with Rasch analysis to produce 
estimates on a linear interval scale (ratings: 0-100). Similar to the index for ocular surface diseases, 
the ocular comfort index (ICO) assesses symptoms. The ICO contains 8 items (one positive and eight 
negative) that focus on discomfort associated with ocular surface alterations. Each of these questions 
has two parts, which separately inquire about the frequency and severity of symptoms.  [43]See 
attachment 16.4 Eye Comfort Index (JI) 
At the baseline visit and final visit, the evaluator will deliver the questionnaire to the subject and allow 
the subject to answer it calmly without any pressure and/or coercion, only assisting him if he has 
difficulty understanding any of the questions.

As it is a subjective measurement scale according to the subject's symptomatology, variations in the 
ICO cannot be managed as AEs.  
 
7.5 Description of procedures or assessments during the study 
The different procedures that will be done during the study are described below. The list may not be 
in order, and it may be arranged in the most optimal way according to the needs of the research

It is the assessment that the subject meets all the inclusion criteria and none of the exclusion or 
elimination criteria. 
7.5.4 Assigning Subject Code 
It is the granting of a code that represents the subject in the study. This code is assigned when the 
research subject is included in the study. 
7.5.5 Adverse events 
Described in the 8. Evaluation and management of adverse events 
7.5.6 Vital Signs Measurement 
It is the measurement of respiratory rate, heart rate and blood pressure. These measurements can 
be made with a stethoscope and mercury or digital sphygmomanometer. 
7.5.7 Urine Pregnancy Test 
The pregnancy test will be performed at the baseline visit and at the final visit. The Researcher must 
provide the research subject with a female, of reproductive age (there is no natural or induced 
menopause, defined as 12 consecutive months of amenorrhea). Women of childbearing potential 
with contraceptive methods including bilateral tubal obstruction should take a pregnancy test. To 
perform the test, the subject will be allowed to go to the bathroom, have privacy for the performance 
of the test, and after the test is performed, the Investigator must corroborate the result by observing 
the medical device.  [45] 
7.5.8 Ophthalmological evaluation 
Evaluation of your eyeball, eyelids, eyelashes, and other structures of your eyes by inspection, slit 
lamp (biomicroscopy), as well as palpation (touch). As part of this evaluation, visual acuity is taken 
with better corrected visual acuity, the integrity of the ocular surface is assessed, the anterior 
segment, intraocular pressure is taken, gonioscopy is assessed, and posterior segment (fundoscopy) 
is assessed. 
7.5.8.1 Best-corrected visual acuity 
Described in the 7.4.4.4 Best-corrected visual acuity 
7.5.8.2 Ocular Surface Integrity 
This will be done by means of biomicroscopy using the slit lamp of the research center. An inspection 
of the cornea, conjunctiva, tear film, and fluorescein eye staining will be done (in section 7.4.4.5

7.5.8.3 Previous segment 
It is the evaluation of the structures of the anterior segment (cornea, conjunctiva, anterior chamber, 
iris, pupil, lens, aqueous humor). The evaluation will be made by means of the slit lamp. 
7.5.8.4 Intraocular pressure 
Tonometry is the objective measurement of IOP, based primarily on the force required to flatten the 
cornea or the degree of corneal indentation produced by a fixed force. Goldmann tonometry is based 
on the Imbert-Fick principle. [46] 
The tonometry will be performed with a Goldmann tonometer, after instillation of the topical 
anesthetic, with fluorescein and the use of the cobalt blue filter (after the evaluation of the surface 
staining). 2 samples will be taken and the average will be calculated, which will be recorded in the 
clinical file. 
7.5.8.5 Gonioscopy 
It is the assessment of the iridocorneal angle by attaching a gonioscopy lens to the subject's cornea. 
In some cases the lens will be filled with a high viscosity solution (2% hypromellose) to improve the 
coupling of it with the subject's cornea.  
This evaluation will be carried out only at the baseline visit as part of the comprehensive 
ophthalmological check-up and will be useful to corroborate the subject's ophthalmological health 
status. 
For the classification of the angle, the Shaffer system will be used.

7.5.8.6 Posterior Segment (Fundoscopy) 
Also called ophthalmoscopy. This is the test done with a light and a magnifying glass to look at the 
fundus (optic nerve and retina) through the pupil. Sometimes the pupil will need to be dilated so that 
the fundus of the eye can be fully evaluated.  
This evaluation will be carried out only at the baseline visit as part of the comprehensive 
ophthalmological check-up under pharmacological mydriasis and will be useful to corroborate the 
subject's ophthalmological health status. 
 
7.5.9 Application of Medications During Visits 
During the visits to the subjects, different medications or medical devices may be applied to the 
ocular surface for ophthalmological examination.  
Examples:  
• 
Tetracaine 0.5% ophthalmic solution, used to anesthetize the subject's ocular surface and 
facilitate the measurement of intraocular pressure, application of dyes for stains and 
placement of the lens for gonioscopy. 
• 
Ophthalmic solution of tropicamide 0.8% and phenylephrine 5%, used to dilate the pupil and 
better assess the posterior segment.  
• 
Hypromellose ophthalmic solution 2%, may be used by the Investigator for the assessment 
of gonioscopy.  
7.5.10 Delivery of material for the subject 
It refers to the delivery of the subject's identification card and the subject's diary. The ID card will 
serve as an ID with the treatment assignment number, this card may serve as an appointment card. 
The Subject's Diary serves to keep track of the times the treatment is applied. 
7.5.11 Delivery of Study Medication 
Once the subject is in the study, the investigational product will be given, and the dosage of the 
product will be explained (one drop three times a day in the right eye). 
7.5.12 Evaluation of concomitant medicinal products 
It is the question about the use of medications that they are taking regularly or that they have used 
in the last month. If you have required injected eye drug therapy, you should ask about the injected 
drugs in the last 6 months.

7.7.5 Unscheduled follow-up visits 
At the request of the subject or personnel related to the study, unscheduled follow-up visits may be 
carried out for the reporting of adverse events or any situation that warrants it. During these visits, 
all pertinent data on the adverse events reported should be collected and, where appropriate, an 
appropriate management plan should be established. 
 
7.8 Data collection 
7.8.1 Source documents 
Source documents are all written or printed records derived from automated processes (e.g., 
printouts of laboratory results issued by automated analysis equipment) where the information is 
recorded for the first time and which is part of the permanent records of the subject's history. 
Examples of source documents are the medical history, clinical evolution notes, laboratory reports, 
cabinet study reports, nursing notes, follow-up notes, surgery records, etc.

   Page  54 de 90 
The PI is obliged to accept the monitoring of the information related to the study, audits, review by 
ethics and research committees, and inspections by the health authority, this obligation implies 
direct access to the source documents.  
7.8.2 Electronic forms of data collection 
All data related to the protocol will be captured through an electronic Case Report Form (eCRF) by 
the investigation team staff. The data related to the protocol should NOT be captured directly in the 
eCRF, but should be transcribed from the corresponding source document. This procedure allows 
monitoring to verify the information captured in the eCRFs. It is the responsibility of the researcher 
to ensure that the information is transcribed into the eCRFs in a correct, complete, and timely 
manner. It is understood that all data captured and sent by the eCRF to data analysis is approved by 
the Researcher.  
7.8.3 Archiving 
The data collected in this database is anonymous (it only stores the subject number together with 
other information of interest). The program used for data capture and storage covers the traceability 
requirements necessary for the execution of clinical studies. The data collected will be stored by the 
sponsor or the clinical research organization designated for this purpose and its storage will have a 
duration of 10 years. The master file will remain in the participating institutions in charge of the PI or 
its work team and must be safeguarded for at least 5 years.

8. Evaluation and management of adverse events 
8.1 Regulation and regulations on adverse events 
The registration and reporting of adverse events will be carried out in accordance with the guidelines 
established in NOM-220-SSA1-2016 and the international guidelines ICH E6.   [33][47][48][49] 
 
8.2 Definition of Adverse Event 
According to the International Council on Harmonization (ICH), an adverse event (AE) is any 
unfavorable medical appearance in a clinical investigational subject who is administered a 
pharmaceutical product, regardless of causal attribution. [47] [48] [49] 
Therefore, an AE can be any of the following: any unfavorable and unintentional disease, symptom, 
or sign (including an abnormal laboratory finding) that is temporally related to the use of a medical 
product, whether or not it is considered related to such a product; any new illness or exacerbation 
of an existing disease (worsening of the nature, frequency, or severity of a known condition); relapse 
of an intermittent medical condition (e.g., headache) not present at baseline; any deterioration in a 
laboratory value or other clinical test (e.g., electrocardiogram [ECG], x-ray) that is related to 
symptoms or that results in a change in study treatment or concomitant treatment or discontinuation 
of study medication. [47] [48] [49] 
As defined in the previous paragraph, an adverse event is defined as any event that occurs during 
treatment with a drug or device. However, the definition can also be applied as any unwanted event 
that occurs during a clinical trial, including behavioral disorders. [49] 
 
8.3 Use of adverse events as a study safety variable 
Measuring the safety of the use of PRO-231 is paramount to the study, therefore, it is considered 
important to report any unwanted manifestations or diseases that occur during the course of the 
study, regardless of whether or not the manifestation is considered to be related to the treatment 
under investigation. [49] 
 
8.4 Definitions relevant to the classification of adverse events  
Severity (serious/non-serious), also called seriousness (serious/non-serious). Serious or serious is 
defined as any event that: results in death, threatens life, requires hospitalization or prolongs 
hospitalization, is a cause of permanent or significant disability or disability, is the cause of alterations 
or malformations in the newborn, other medically important conditions (Medically important event

or reaction: That clinical manifestation or adverse event that in the opinion of the doctor may not be 
immediately life-threatening,  result in death or hospitalization, but which could endanger the subject 
or require medical intervention to prevent the occurrence of any of the criteria listed in the definition 
of serious adverse reaction).  [50] 
Severity (mild, moderate, or severe). Mild are those that present with minimal symptoms, do not 
require treatment or suspension of the medication; moderate, when they interfere with usual 
activities, without threatening the subject's life, require treatment and may or may not require 
discontinuation of the medication; severe, those that interfere with usual activities and require 
pharmacological treatment and discontinuation of the medication.   [33][47][48] 
Causality. It is the relationship that is assigned between the pharmaceutical product and the adverse 
event: certainly caused by the pharmaceutical product, there is clear evidence of causality, i.e. the 
adverse event reappears with the administration of the pharmaceutical product; probably caused by 
the pharmaceutical product, there is a high suspicion of causality but no direct evidence is available 
or it is considered unnecessary or dangerous, i.e. the reaction disappears when the pharmaceutical 
product is discontinued; possibly caused by the pharmaceutical, there is additional information to 
suggest that the cause may be due to another pharmaceuticals or disease; unlikely to be caused by 
the pharmaceutical product, there is a clear explanation of the origin due to the underlying disease 
or the use of another pharmaceutical product; conditional, there is a lack of data to issue a clear 
causality; non-classifiable, those for which once all possible information has been obtained about the 
adverse event, it remains unclassifiable.     [33] [47] [48] [49] 
 
8.5 Responsibilities of the researcher  
It is the responsibility of the Investigator to verify AEs through questioning, pertinent physical 
examination, assessment of evolution, as well as appropriate medical and pharmacological 
management; as well as to follow up until the resolution or outcome and definitive discharge of the 
AE, following the definitions determined in national and international regulations. [33] [47] [48] 
In the event of an AE or any event that puts the health and well-being of the subjects at risk, pertinent 
medical care will be provided, either at the research center or will be referred to the Hospital Center 
with the highest resolution power with which the research center has a medical care agreement. The 
PI will notify the sponsor's clinical monitor, according to the times established in national and 
international regulations. In the case of serious adverse events, it will notify the sponsor and record 
the corresponding information in the eCRF and in turn, inform the IRB and IC.   
The attention of the AEs will be carried out according to the event care diagram (see Figure 3. Adverse 
Event Care).  
The sponsor's final report will include the report of adverse events in compliance with current 
national and international regulations. [33] [47]

If the research subject debuts during their participation in the study with any chronic adverse event, 
such as diabetes or systemic arterial hypertension, they will be referred to the competent health 
professional for chronic treatment. The follow-up and termination of their participation will be in 
accordance with the stipulations of NOM-012-SSA3-2012. [33] 
8.5.1 Recording of adverse events in the electronic case report form  
The adverse event registry considers:  
▪ 
Subject identification information such as: subject number, age, gender, and if applicable 
specify the eye.   
▪ 
Information about the causality of the adverse event, its relationship to investigational 
products, or to another drug related to the study, as appropriate.  
▪ 
Important date information:  
o 
Date on which the adverse event occurs.  
o 
Date on which the Principal Investigator becomes aware of it.  
o 
Date of resolution or outcome, as applicable.   
▪ 
Information on diagnosis and clinical management.   
▪ 
Record the outcome or resolution of the event:   
o 
Recovered/resolved  
o 
Recovered/resolved with sequelae  
o 
Recovering/Resolving 
o 
Not Recovered/Unresolved  
o 
Subject who presented death due to the adverse event  
o 
Subject who presented death and it is judged that the research product may have 
contributed  
o 
Subject who presented death and this is not related to the product under 
investigation 
o 
Unknown  
▪ 
Information about the investigational product or product associated with the Adverse Event, 
Incident, Adverse Incident, AMR or SRAM must be recorded. The information essential for 
registration is the generic name, distinctive name or code of the investigational product or of 
the product associated with the undesirable clinical manifestation; it will also be necessary to 
enter the data concerning the batch number, manufacturing laboratory, expiration date, dose, 
route of administration, start and end dates of administration and/or consumption, reason for

prescription; according to whether it is an investigational product or drug (protocol in which 
the subject currently participates) or whether it is a drug that the research subject consumes 
for the treatment of underlying concomitant diseases or uses for the management of some 
transitory sign or symptom that does not correspond to the Natural History of the pathology 
that motivated its entry into the research protocol.  
▪ 
Indicate whether the removal of the suspected product (of causing the event) eliminates the 
adverse event. Also indicate if a dose adjustment is made, if the event changes in terms of 
intensity or seriousness, persistence of the reaction. It is important to indicate whether in 
those subjects who are exposed again to the product, which had previously been suspended, 
the AD reappears.   
▪ 
Information regarding concomitant pharmacotherapy. Indicate the generic name, the dose, 
the route of administration, start and end dates of its use, as well as the reason for the 
prescription, regardless of whether it is in accordance with the prescribing information or 
technical data sheet or is used outside the regulations or what has been authorized by the 
local, national or international regulatory authority.  
▪ 
Relevant medical history information. The analysis of the AE considers the information 
previously narrated, despite the clinical context in which this harmful phenomenon occurs in 
the participants of the clinical research protocol, is of special interest, so the information about 
previous conditions, hypersensitivity or allergy phenomena, previous surgical procedures, 
laboratory analyses or cabinet examinations that have been performed on the participant,  
etc., that the researcher deems it appropriate to mention may do so.  
8.5.2 Adverse Event Tracking  
The Principal Investigator will provide care and follow-up of the adverse event presented by the 
participant until its outcome, according to what is referred to in the following section.  
8.5.2.1 Diagnosis against signs or symptoms 
Whenever possible, an AE should be assessed/reported as a diagnosis and not as a sign or 
symptom (e.g., liver failure or hepatitis rather than jaundice, asterixis, and elevated 
transaminases). If a diagnosis cannot be made from the signs or symptoms, then each sign or 
symptom should be recorded as an AE. If a diagnosis is made later, all AEs reported as signs 
or symptoms should be nullified and replaced by a single adverse event based on the 
diagnosis, with an onset date that corresponds to the onset date of the first symptom or sign 
of the eventual diagnosis. 
8.5.2.2 Adverse events secondary to other adverse events 
In general, AEs secondary to other AEs (cascading events or sequelae) should be identified 
according to the primary cause, with the exception of serious events. A medically important 
AE secondary to an AE that is separated in time from the initial event should be reported as 
a separate event in the EA section of the eCRF. For example:

   Page  59 de 90 
If vomiting results in mild dehydration without additional treatment in a normal adult, 
vomiting should only be reported on the eCRF. 
If vomiting results in severe dehydration, both events should be reported separately on the 
eCRF. 
If severe gastrointestinal bleeding leads to renal failure, both events should be reported 
separately on the eCRF. 
If a dizziness event leads to a fall and subsequent fracture, then all three events should be 
reported separately in the eCRF. 
If neutropenia is accompanied by infection, both events should be captured independently in 
the eCRF. 
All EAs must register separately if there are concerns regarding the association of events. 
8.5.2.3 Persistent or recurrent adverse events 
A persistent adverse event is one that spreads continuously without resolution between 
different points of assessment of the subject. Such events only need to be registered once in 
the eCRF. The initial severity (intensity or degree) of the event will be recorded at the time of 
the first AD record. If a persistent AE becomes acute, the maximum severity should be 
recorded in the appropriate section of the eCRF. If the event becomes a serious event, it must 
be reported no later than 24 hours after the knowledge of the change in the status of the 
event. The eCRF section should be updated to reflect the serious status, and will record the 
date on which the event became serious, thus completing all relevant serious EA reporting 
data. 
A recurrent AE is one that resolves between assessment points and subsequently reappears. 
Each recurrence of the EA must be recorded separately in the eCRF. 
8.5.2.4 Abnormal vital signs 
Not all abnormal vital signs qualify as AS. For an abnormal vital sign to be reported as an AD, 
it must meet any of the following criteria:  
- 
Be accompanied by clinical symptoms. It results in a change in treatment (dose 
modification, treatment interruption, etc.). 
- 
The report of abnormal values should focus on obtaining a diagnosis and not just a 
description of the abnormality. 
8.5.2.5 Death 
Death should be considered an outcome and not an event. The event or condition that caused 
or contributed to the fatal outcome should be recorded as the EA in the eCRF section.

   Page  60 de 90 
8.5.2.6 Pre-existing medical conditions 
A pre-existing medical condition should be recorded as AE only if the frequency, severity, or 
characteristics of the condition worsen during the study. 
8.5.2.7 Hospitalization or prolonged hospitalization 
Any AE that results in hospitalization or prolongation of hospitalization must be documented 
or reported as a serious AE with the following exceptions: 
Hospitalization for pre-existing conditions as long as the following are met: 
Hospitalization was planned before the study. 
8.5.2.8 Pregnancies, miscarriages, and birth defects 
Fertile women should contact their doctor to report any suspected pregnancy during the 
study. A pregnancy report must be issued and the sponsor must be informed immediately. 
Monitoring of the subject should continue until the outcome of pregnancy. Pregnancy is not 
by itself an AE. 
Any abortion should be classified as a serious AE. 
Any birth defect or birth defect in a product from a woman who received the study drug should 
be classified as a serious AE. 
8.5.3 Procedures for a serious adverse event  
The process of attention to the adverse event considers the following stages:

Figure 3. Adverse Event Care 
During the development and conduct of this study, undesirable harmful events or adverse 
reactions/incidents, of medical implication, may occur in the research subject, which do not 
necessarily have a causal relationship with the investigational products. These harmful phenomena 
can occur during the use of investigational pharmaceutical products at doses authorized for use in 
humans by a local, national or international regulatory authority. However, it may be suspected that 
the investigational product causes some unwanted clinical manifestation. AEs, Incidents, Adverse 
Incidents, ADRs or SRAMs to one or more pharmaceutical products can occur during the systematic 
evaluation of the participants (on the days when the clinical review is scheduled, according to the 
schedule of activities) or suddenly, in such a way that:  
1. The investigator must be the first person to whom the subject notifies that he or she 
has developed or presented any harmful phenomenon of a clinical nature during his or 
her participation in this study.

or Summary of the Comparator Drug, the principal investigator determines the pertinent 
care of the harmful event/reaction.  
3. Such care can be in the research center or in the hospital with the greatest resolution 
power. In such a way that, in the event that the subject is sent by the PI to a hospital, he 
or she attends through a referral system. The reference can be with a card that identifies 
the subject as a study participant and links him or her to the pre-established agreement 
with the institution, or through a medical reference note issued by the Principal 
Investigator. Laboratorios Sophia, S.A. de C.V., will pay the expenses for the medical care 
of the participating subject, when the adverse event is associated with or related to the 
product under investigation.  
4. Taking the clinical information collected, either during the care provided at the 
research center or that provided by the treating physician(s) in the hospital, the PI will 
record the AE in its clinical note, stating the seriousness, intensity (mild, moderate or 
severe) and relationship with the investigational product.   
5. The PI must migrate the relevant data to the eCRF and its respective adverse event 
section. By virtue of the fact that, in cases of serious adverse events, the clinical monitor 
of the study must be notified within 24 hours after learning of it, so that in turn it informs 
the Clinical Team and the Pharmacovigilance and Technovigilance Unit of Sophia 
Laboratories (UFTLS), and that the CEI/CI is subsequently notified. Non-serious adverse 
events will be recorded and treated appropriately and the safety profile of the 
investigational drug or drug will be reported to the appropriate regulatory authority in 
the final report of the clinical trial.  
The recording of the outcome of the AE depends substantially on the follow-up that the Principal 
Investigator performs on the subject, since it is expected that most of the harmful phenomena (see 
subsection 2.5 Risk-benefit assessment and consult the Investigator's Manual) are ophthalmic in 
nature, however, there may be systemic alterations. Therefore, in the opinion of the researcher, the 
withdrawal of the participant or their permanence will be considered.  
8.5.4 Causation assessment  
Causality assessment is the methodology used to estimate the probability of attributing the observed 
adverse event to a pharmaceutical product. It considers probabilistic categories according to the 
available evidence and the quality of the information, based on the national pharmacovigilance and 
technovigilance regulations, the World Health Organization and the Uppsala Monitoring Center.  
[33][51] 
An adverse event may or may not be related to the clinical trial. A causal relationship means that the 
intervention caused (or is reasonably likely to have caused) the adverse event. This usually implies a 
relationship between the time of the intervention and the adverse event (e.g., the adverse event 
occurred shortly after the subject under investigation received the intervention). [49] 

Laboratorios Sophia, S.A. de C.V.

C O N F I D E N C I A L 
   Page  63 de 90 
For all adverse events, the Principal Investigator is responsible for examining and evaluating the 
subject to determine the association of the event with the clinical study and the intervention, 
whether related to the experimental treatment, concomitant, surgical procedure, or diagnostic 
procedures performed during the study. [49] 
Accepting that the adverse event is related to the clinical study requires a plausible mechanism of 
action, that is, that there is a logical sequence between the event that occurred and the intervention 
that caused it. In some cases, it is helpful to know the opinion of other doctors directly or indirectly 
involved in the research; as well as whether the subject considers that a relationship exists or not. 
[49] 
UFTLS may employ the causation categories described by the Uppsala Monitoring Centre, to 
categorize the likelihood of adverse event to the investigational product or concomitant treatments 
or treatments used during visits: [33] [51] 
• 
Definitive (certain): a clinical event, including alterations in laboratory tests, that manifests 
itself with a plausible temporal sequence in relation to the administration of the drug, and 
that cannot be explained by concurrent disease, or by other drugs or substances. The 
response to drug withdrawal (withdrawal) must be clinically plausible. The event must be 
definitive from a pharmacological or phenomenological point of view, using, if necessary, a 
conclusive re-exposure (challenge) procedure. [33] [51] 
• 
Probable: A clinical event, including alterations in laboratory tests, that manifests itself with 
a reasonable time sequence in relation to the administration of the drug, that is unlikely to 
be attributed to concurrent disease, or to other drugs or substances, and that a clinically 
reasonable response is presented upon withdrawal. It is not necessary to have re-exposure 
(challenge) information to assign this definition [33] [51] 
• 
Possible: A clinical event, including alterations in laboratory tests, that manifests itself with a 
reasonable time sequence in relation to the administration of the medicinal product, but 
which can also be explained by concurrent disease, or by other drugs or substances. 
Information regarding the withdrawal of the drug may be missing or unclear. [33] [51] 
• 
Unlikely: A clinical event, including alterations in laboratory tests, that manifests itself with 
an unlikely temporal sequence in relation to the administration of the drug, and that can be 
more plausibly explained by concurrent disease, or by other drugs or substances. [33] [51] 
• 
Conditional/Unclassified: A clinical event, including alterations in laboratory tests, reported 
as an adverse reaction, for which further data are essential for appropriate evaluation, or 
additional data are under review. [33] [51] 
• 
Non-assessable/Unclassifiable: A notification that suggests an adverse reaction, but cannot 
be judged because the information is insufficient or contradictory, and that cannot be 
verified or completed in its data. [33] [51]

Thus, the degree of certainty to establish the investigational product as the causal agent of the 
harmful phenomenon that occurs to the subject of the clinical study, can be indicated directly by the 
Principal Investigator based on his clinical experience or by applying the categories of causality 
described by the Uppsala Monitoring Centre. It is important that the researcher and the UFTLS take 
into account the following arguments in favor of the causal relationship:   
a) 
Strength of association, which refers to the number of cases in relation to those 
exposed.   
b) 
The consistency of the data, i.e. the presence of a common characteristic or pattern.   
c) 
The exposure-effect pattern, which determines the relationship with the site of 
appearance, time, dose and reversibility after deletion. 
d) 
Biological plausibility, which refers to the possible pharmacological or 
pathophysiological mechanisms involved in the development or presentation of the adverse 
event.   
e) 
Experimental findings, e.g., the appearance of abnormal metabolites or high levels 
of the drug or its biotransformation product.   
f) 
Analogy, which refers to the experience gained with other related drugs, adverse 
reactions frequently produced by the same family of pharmacological agents.   
g) 
Nature and characteristics of the data, i.e. objectivity, accuracy and validity of the 
relevant documentation. [52]

9. Study Monitoring  
The study sponsor is responsible for monitoring the study. Monitoring activities include, but are not 
limited to: general safety monitoring, general study quality monitoring, monitoring by study site, 
detection monitoring, reporting and tracking of adverse events, monitoring for resolution of 
discrepancies in data capture, etc.  
Responsibility for monitoring activities and ultimate responsibility for monitoring rests with the 
sponsor.  
The details of the monitoring activities are specified in a separate document from this protocol in a 
Monitoring Plan.  
 
9.1 Monitoring the Study Site  
The research center participating in the study will be monitored. For each centre, at least one start 
visit and one closing visit must be carried out, which does not exclude the carrying out of one or more 
follow-up visits between these two mandatory visits.  
The initial visit must be carried out before the inclusion of the first participant in that center; In it, 
the monitor will verify that the material to be used during the study has been received and that the 
personnel who will participate in the study activities have been trained on the study, as well as verify 
that the regulatory requirements and applicable standard operating procedures are met.  
At the follow-up visit(s), the monitor will conduct a review of the study documents to confirm that 
the applicable research protocol and standard operating procedures are being followed, data 
completion is complete and timely, and that adverse event reports are being conducted 
appropriately. At each visit, the monitor will discuss the findings with the researcher and define the 
actions to be taken.  
The closure visit will take place at the end of the study, once the last site participant has been 
discharged from follow-up. On this visit the monitor will verify that the site has all the necessary 
documents for archiving, that all biological samples have been analyzed, that all IP (used and unused) 
has been returned to the sponsor, and that all unused material has been recovered.  
Details on monitoring are set out in the corresponding plan. 
 
9.2 Audit and quality assurance  
To ensure compliance with Good Clinical Practice (GCP) and all applicable regulatory requirements, 
Laboratorios Sophia, S.A. de C.V. may conduct quality assurance audits. Regulatory agencies could 
also conduct a regulatory inspection of this study.

Details about the audit process are set out separately in the Audit Plan.  
They may take place at any time before, during, or after the conclusion of the study. If any audit or 
inspection is conducted, the investigator and the institution shall agree to allow the auditor/inspector 
direct access to all relevant documents, and shall allocate their time and that of their staff to the 
auditor/inspector to discuss the findings and any pertinent problems. In the event that the audit has 
not been scheduled by the sponsor, the facility must notify Laboratorios Sophia, S.A. de C.V. 
immediately.

10. Sample size calculation and statistical analysis 
10.1 Sample Size Calculation 
Bacterial conjunctivitis is commonly self-limiting, resolving after about 10 days, and can rarely last 
more than 3 weeks. Its most common treatment is the use of antibiotics with a broad spectrum of 
action on the variety of ocular pathogens. Proper management of bacterial conjunctivitis reduces the 
time to resolution of the disease, minimizes the risk of sequelae, helps prevent the spread of 
infection, and decreases the time the patient can spend away from work or school. Moxifloxacin 
hydrochloride is a fourth-generation fluoroquinolone, its use in topical ophthalmic presentation for 
the treatment of bacterial conjunctivitis has been approved since 2003 in the United States. 
Moxifloxacin is one of the most potent fluoroquinolones evaluated for ophthalmic use for bacterial 
eradication. There is sufficient evidence on the safety and tolerability of moxifloxacin. Commonly 
reported AEs are eye pain, eye burning/irritation, hyperemia, and tearing; most of them of mild 
intensity and transient.[53] [54, 55] [54] [53, 55, 56, 57, 58] 
Considering this information and the primary objective of the study; To evaluate the safety and 
tolerability of PRO-231 ophthalmic solution (moxifloxacin 0.5%) on the ocular surface of clinically 
healthy subjects, the following proposal was made for the sample size. 
10.1.1 Calculation methodology 
Although sample estimation in phase 1 studies is common in treatments whose toxicity/risk is high, 
as it is in clinical studies for the management/survival of cancer; It was considered pertinent to 
estimate the sample size according to the safety profile reported in the literature after the use of 
moxifloxacin hydrochloride. Considering the primary safety variables of the protocol: [59] 
• 
Incidence of AD 
• 
Changes in ophthalmologic signs  
• 
Changes in the AVMC 
• 
Changes in fluorescein staining of the ocular surface 
 
The equation was used to compare two proportions: two samples, two sides of equality. This 
calculation is useful when you want to test whether the proportions of two groups are different 
(Incidence of AD in VIGAMOXI® is different from the incidence of AD in PRO-231). The following 
formulas are used for the calculation to compute the sample size and power respectively:  [60]

The proportion of subjects who had at least one AE (ocular and non-ocular) was considered in the 
study by Garg et al. (2015), where they evaluated the clinical and antibacterial efficacy, as well as the 
safety of besifloxacin ophthalmic suspension compared to moxifloxacin 0.5% (besifloxacin; n=61, 
moxifloxacin; n=62). A total of 6 ocular AEs were present in subjects treated with moxifloxacin and at 
least one AE occurred in 3 patients. The most common AE was conjunctivitis (3.2%). For the expected 
proportion of subjects of PRO-231, 50% was used, which is a conservative value and gives larger 
samples. The calculation was made using the free software R (R Core Team, 2021), using a code 
available online for this purpose. [56] [61] [62] 
10.1.2 Size Calculation 
PRO-231 ophthalmic solution is expected to be safe in its ophthalmic application as it presents an 
incidence of AE similar to that presented by VIGAMOXI.® 
On this basis, a sample of 17 ophthalmologically and clinically healthy subjects was estimated. This 
value increased by 10% considering possible losses. Based on this consideration, 19 subjects per arm 
(38 subjects in total) are required to provide one eye (OD) to respond to the primary objective of the 
study. 
 
10.2 Clinical Data Management 
The clinical data management (or clinical data management, CDM), allows the generation of high-
quality, reliable data with statistical value. CDM is the process of collecting, cleaning, and managing 
the information of the subjects of a study in accordance with regulatory standards (guidelines 21 CRF

The statistical analysis will be carried out by personnel of Laboratorios Sophia, S.A. de C.V. Specialized 
statistical software (SPSS version available [IBM Corporation, Armonk, NY, USA] or R [The R 
Foundation for Statistical Computing; http://www.R-project.org]), for Windows. The coding will be 
done using consecutive numbers. The data will be collected and sorted in an Excel spreadsheet 
(Microsoft® Office). The data will then be exported to the platform of the selected statistical package. 
The variables will be categorized according to their nature (see Board 2). The statistical tests used will 
be following the corresponding assumptions for parametric statistics as long as the assumption of 
normality is met (Shapiro-Wilk, p>0.05). 
10.3.1 Population Analysis 
The statistical analysis will be presented to give a general summary of the subjects entered into the 
study and a view of the safety and tolerability of its results. The data provided by the research site 
will be summarized for this purpose, according to its nature. The Shapiro-Wilk test will be performed 
to find out if the quantitative data are distributed in a normal way (p>0.05).  
The results of the quantitative variables will be presented in measures of central tendency: mean, 
standard deviation and/or ranges. Changes in the AVMC and ICO will be expressed as continuous 
variables. Whereas, the incidence (number) of AEs will be expressed as a discrete variable. 
The result of the nominal and ordinal qualitative variables will be presented in frequencies, 
proportions and/or percentages. For these, tables of frequencies p x q will be constructed. All 
percentages will be presented with a decimal. 
The level of difference to consider significance will be an alpha (α) of 0.05 or less, the 95% CI will be 
calculated for these differences. The triangulation between the type of variable and the 
measurements is shown in Table 5. [63] 
The operational definition of the study for hypothesis testing will be as follows:  
 
Hypothesis 
testing 
value 
Result 
Interpretation 
P value 
≤ 0.05 
H0 
rejected 
Both treatments are different in terms of safety and 
tolerability 
95% CI 
Does not 
include zero 
P value 
≥ 0.05 
H0 
accepted 
Both treatments are similar in terms of safety and 
tolerability (they are not different) 
95% CI 
Includes zero 
 
Both conditions for hypothesis testing (p-value and 95% CI) must be met, otherwise the result 
will be interpreted as "absence of evidence", not as "evidence of absence".

10.3.2 Safety and tolerability analysis 
10.3.2.1 Analysis for Primary Variables 
The analysis of the primary outcome variables of safety and tolerability will be carried out in the per-
protocol population (PP), defined as any subject with an adherence ≥ 80% determined by the 
subject's diary and corroborated by the final weight of the research product to which it was assigned 
(PRO-231 or VIGAMOXI)® with respect to its initial weight.  and that they conclude their participation 
without deviations from the study protocol. 
The Shapiro-Wilk test (S-W) will be used to determine if the distribution is normal in the data obtained 
in each study group (p>0.05). If the normality in the distribution of the data is verified, to rule out 
differences between groups, the Student's t-statistic will be used for independent groups, while 
intragroup differences will be analyzed with the Student's t-test for repeated measures.

In case of p<0.05 in S-W, the statistical analysis to rule out differences between groups will be 
performed by means of the Mann-Whitney U test for quantitative variables, while intragroup 
differences will be performed by Wilcoxon's rank test. 
For qualitative variables, Pearson's X2 (Chi-square) or Fisher's exact test will be used in expected 
values less than 5. Dichotomous variables will be analyzed by the McNemar test when applicable. 
10.3.2.2 Analysis for secondary variables 
The analysis of the secondary outcome variables of safety and tolerability will be carried out in the 
safety population, defined as any subject who has received at least one dose of the investigational 
product (PRO-231 or VIGAMOXI)® regardless of their adherence to it or adherence to the protocol 
(intention-to-treat population, ITT). 
For the analysis of these variables, the same primary analysis will be carried out as long as they have 
the necessary measurements to do so. 
 
10.4 Other analyses 
The final report of the results will be shown in tables or graphs, as appropriate. 
10.4.1 Procedure for handling missing data 
There is no imputation procedure for missing data.

have been corrected; as long as this justification is sufficient for the sponsor, CI, CEI and regulatory 
authorities. 
 
11.4 Informed Consent  
The FCI contains complete and understandable information about the study and the investigational 
product, in accordance with the applicable regulations in force and Good Clinical Practice.   
The FCI will be considered as a source document and will be filed as such. The site's principal 
investigator is responsible for ensuring that all new versions of the informed consent are submitted 
to the appropriate approvals (the same as those to which the original informed consent form was 
submitted) and that the most current approved version is the one presented to the study subjects. 
11.4.1 Obtaining  
Informed consent must be obtained before the subject undergoes any procedure indicated in the 
protocol. For this purpose, the informed consent form must be signed.  
Written consent documents will incorporate the elements of informed consent described in the 
Declaration of Helsinki and the ICH Guide to Good Clinical Practice and will be in compliance with all 
applicable laws and regulations.  
The PI, or the study staff delegated by him/her, will provide the prospective participant with all the 
information regarding the characteristics of the study, its potential benefits, risks, objectives, and 
procedures.  
This information will be in a language understandable to the subject, it will be explained to the subject 
that he or she has the right to interrupt his or her participation in the study at any stage, without this 
affecting the relationship with the researcher and/or his or her future assistance. Informed consent 
will be put to the consideration of the potential participant; He must have enough time to analyze 
each and every one of the aspects mentioned above and in case he has any doubts, it will be clarified 
by the person in charge of obtaining the informed consent.   
Once the participant agrees to participate in the study, he/she must sign and date the informed 
consent form in the presence of two witnesses who are or are not related to the study subject, who 
will participate during the informed consent process and will sign guaranteeing that the process was 
carried out prior to any study procedure.  that the information of the study was clearly explained and 
doubts were clarified if any.  
In the event that a subject is illiterate, acceptance will be with his or her fingerprint, and in the event 
that the subject is unable to give adequate written informed consent, a representative of the "legally
