Clinical Trial Summary

Phase I clinical study, to evaluate the safety and tolerability of the ophthalmic solution PRO-179 compared with Travatan®, on the ocular surface of clinically healthy subjects.

Goals: To evaluate the safety and tolerability of the formulation PRO-179 manufactured by Sophia Laboratories S.A. of C.V. on the ocular surface of clinically healthy subjects.

Hypothesis:The ophthalmic solution PRO-179 presents a profile of safety and tolerability similar to Travatan® in healthy subjects.

Methodology: Clinical trial Phase I, controlled, of parallel groups, double blind, with randomization.

Description:

Number of patients: n= 24, 12 subjects per group (both eyes). Main inclusion criteria:

Clinically healthy subjects.

duration: 10 days.

Duration of subject in the study: 15 to 22 days.

Adverse events will be reported and cataloged based on the MedDRA dictionary and will be reported to the corresponding regulatory entity.

The sponsor will carry out monitoring or quality visits to the research sites where it corroborates the information of the source documents and will contrast them with the information presented in the electronic CRF. Electronic case report forms will be evaluated by the clinical research associate and the clinical team of the sponsor (medical ophthalmologist researcher and pharmacologist of clinical safety).

Statistical methodology:

The data will be expressed with measures of central tendency: mean and standard deviation for the quantitative variables. The qualitative variables will be presented in frequencies and percentages. The statistical analysis will be carried out by means of the Mann-Whitney U test for the quantitative variables for the difference between the groups. The difference between the qualitative variables will be analyzed by means of X2 (Chi2) or Fisher's exact. An alpha ≤ 0.05 will be considered significant.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Changes in Intraocular Pressure	the intraocular pressure will be evaluated by means of the Goldman applanation tonometry whose unit of measurement is millimeters of mercury (mmHg), it is a continuous variable and its normality range is between 11 - 21 mmHg	will be evaluated at the end of the treatment, at the final visit (day 11)
Primary	Number of Participants With Adverse Events	primary security variable the adverse events will be evaluated with a scale of Present / Absent, it is a nominal variable, the normal value is absent. it will be evaluated by the number of reported cases per group.	during the 14 days of evaluation, including the safety call (day 14).
Primary	Eye Comfort Index	It is a questionnaire designed to measure the irritation of the ocular surface with Rasch analysis to produce estimates on a linear scale of intervals (ratings: 0-100).The Eye comfort index contains items that focus on the discomfort associated with alterations of the ocular surface.(0: None discomfort, 100: high discomfort).	will be evaluated at the end of the treatment, at the final visit (day 11)
Secondary	Number of Eyes With Epithelial Defects by Grade	The epithelial defects will be evaluated by means of two stains, lissamine green and fluorescein, it is a discrete variable that will be realized by direct observation, it will be staged according to the degrees of the oxford scale that go from 0 to 5 (0-V) according to its severity, where 0 is the normal lower limit and 5 the upper limit of defects.	will be evaluated at the end of the treatment, at the final visit (day 11)
Secondary	Visual Ability	The visual capacity variable will be reported using as a unit of measure a fraction, this is taken from a visual test with the Snellen primer, it is a Nominal type variable. where the optimal vision is 20/20 and the worst vision is 20/200, higher values represent a worst vision. The result of the Snellen chart has equivalents in an international logarithmic system called Logmar (logarithm of the minimum angle of resolution) for better understanding.; Snellen Scale: 20/200, 20/100, 20/50, 20/40, 20/30, 20/25, 20/20, 20/15, 20/12, 20/10.; Snellen / LogMAR equivalences: 20/200= 1.0, 20/100=0.7, 20/50=0.4, 20/40=0.3, 20/30=0.2, 20/25=0.1, 20/20=0.0, 20/15=0.13, 20/12=0.2, 20/10=-0.3, etc.	will be evaluated at the end of the treatment, at the final visit (day 11)
Secondary	Percentage of Eyes With Conjunctival Hyperemia (CH) by Grade	Conjunctival hyperemia will be evaluated as an ordinal variable, by direct observation and staged using the Efron scale as Normal / Very Light / Mild / Moderate / Severe. Based on this scale, the normal and mild stages are considered without pathologies or normal. Mild, moderate and severe are considered pathological.	will be evaluated at the end of the treatment, at the final visit (day 11)
Secondary	Number of Eyes of Chemosis	The chemosis will be evaluated, as a nominal variable, by direct observation and it will be staged as present and absent, where the normality is that said variable is absent.	will be evaluated at the end of the treatment, at the final visit (day 11)
