Clinical Trial Summary

Title of the study:

Phase I clinical trial, to evaluate the safety and tolerability of the ophthalmic gel PRO-167 versus Corneregel®, on the ocular surface of ophthalmological and clinically healthy subjects.

Methodology:

Phase I clinical trial, controlled, of parallel groups, double blind, randomized, exploratory.

Goals:

To evaluate the safety and tolerability of the ophthalmic gel PRO-167 manufactured by Laboratorios Sophia S.A. of C.V. on the ocular surface of clinically healthy subjects.

Hypothesis:

Ophthalmic gel PRO-167 has a safety and tolerability profile similar to that of its comparator in healthy subjects.


Description:

Therapeutic indication:

Corneal surface reepithelizing

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 through the Mann-Whitney U test for quantitative variables. The difference between the qualitative variables will be analyzed by means of square chi (Chi2). An alpha ≤ 0.05 will be considered significant.

Study period:

3 to 4 months

Development phase: I

Outcome

Type Measure Description Time frame Safety issue
Primary Goblet Cell Density (GCD) the cells will be measured per square millimeter, it is a continuous variable taken by means of cytology per impression, the normal value is higher than 500 cells per square millimeter will be evaluated at the end of the treatment at the final visit (day 11)
Secondary Presence of Adverse Events (EAS) the adverse events will be evaluated with a scale of Present / Absent, it is a nominal variable, the normal value is absent. during the 11 days of evaluation, including the safety call (day 13).
Secondary Intraocular Pressure (IOP) 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)
Secondary Breakup Time (BUT) breakup time lacrimal film is a continuous variable that will be measured in seconds, evaluating the time it takes to break it, is done by direct counting and the normality range greater than 10 seconds. will be evaluated at the end of the treatment at the final visit (day 11)
Secondary 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)
Secondary Ocular Burning (OB) ocular burning is a nominal variable that will be evaluated by direct questioning to the research subject, then it will be staged according to the following scale: Severity: Absent, very mild, mild, moderate and severe, where the normality of severity is absent.Frequency: At all times, almost at all times, 50% of the time, almost in no time, at any time. where the normality of the frequency is in no time. will be evaluated at the end of the treatment at the final visit (day 11)
Secondary Epithelial Defects (ED) The epithelial defects will be evaluated by means of two stains, green lissamine, 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 Conjunctival Hyperemia (CH) 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 Foreign Body Sensation (FBS) Foreign body sensation is a nominal variable that will be evaluated by direct questioning to the research subject, then it will be staged according to the following scale:
Severity: Absent, very mild, mild, moderate and severe, where the normality of severity is absent.
Frequency: At all times, almost at all times, 50% of the time, almost in no time, at any time. where the normality of the frequency is in no time.
will be evaluated at the end of the treatment at the final visit (day 11)
Secondary Ocular Pruritus (P) Ocular pruritus is a nominal variable that will be evaluated by direct questioning to the research subject, then it will be staged according to the following scale:
Severity: Absent, very mild, mild, moderate and severe, where the normality of severity is absent.
Frequency: At all times, almost at all times, 50% of the time, almost in no time, at any time. where the normality of the frequency is in no time.
