Clinical Trial Summary

Study design: Phase I clinical trial, single-center, controlled, parallel group, open, randomized.

Number of subjects: n = 34 evaluable subjects, 17 evaluable subjects per group (both eyes).

Estimated duration of the study: 5 months

Therapeutic indication: Eye lubricant Use: Dry Eye

Objective:To evaluate the safety and tolerability of Lagricel® Ofteno multidose manufactured by Laboratorios Sophia on the ocular surface of clinically healthy subjects.

Hypothesis:

H0 = Lagricel® Ofteno multidose ophthalmic solution has a safety and tolerability profile similar to Lagricel® Ofteno single dose in healthy subjects.

H1 = Lagricel® Ofteno multidose ophthalmic solution has a different safety and tolerability profile than Lagricel® Ofteno single dose in healthy subjects.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Presence of Adverse Events (AEs)	the adverse events will be evaluated with a scale of Present / Absent, it is a nominal variable, the normal value is absent	during the 10 days of evaluation, including the safety call (day 11).
Primary	Eye Comfort Index (ECI)	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 (day 8, final visit)
Secondary	Visual Acuity (VA)	Visual acuity (VA) is a test of visual function. It will be evaluated at baseline, without refractive correction with the Snellen chart.Which will be located in a place with adequate lighting, natural or artificial and at a distance of 3meters from the subject to be evaluated. The snellen chart consists of a booklet with 11 lines composed of letters, each line has a different size and a different weighting. the subject is placed at a safe distance and the contralateral eye to which it will be evaluated is covered, then the examiner detects until the line can clearly see the letters given he or she a score, the normal score for a VA is 20/20.	will be evaluated at the end of the treatment (day 8, final visit)
Secondary	Epithelial Defects (ED) Fluorescein Stain	The epithelial defects will be evaluated by means of two stains, green lysine 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 (day 8, final visit)
Secondary	Epithelial Defects (ED) Green Lissamine	The epithelial defects will be evaluated by means of two stains, green lysine 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 (day 8, final visit)
Secondary	Conjunctival Hyperemia (CH)	Conjunctival hyperemia will be evaluated as an ordinal variable, by direct observation and staged using the Efron scale as 0.-Normal / 1.-Very Light/ 2.- Light/ 3.-Mild / 4.-Moderate / 5.- 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 (day 8, final visit)
Secondary	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 if the conjunctiva separates from the sclera by = 1/3 of the total eyelid opening	will be evaluated at the end of the treatment (day 8, final visit)
