Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objectives: To evaluate the non-inferiority in the intraocular pressure decrease of the preservative-free ophthalmic solution PRO-122, manufactured by Laboratorios Sophia S.A. de C.V., versus concomitant therapy in subjects with uncontrolled primary open-angle glaucoma and/or IOP.

Hypothesis: The mean (average) value of the IOP final absolute reduction in the experimental group (PRO-122) is not lower, considering a lower limit of 1 mmHg, compared to the IOP mean absolute reduction of the standard group (concomitant therapy).

Methodology: A non-inferiority, phase III, double-blind, randomized, controlled, parallel, clinical trial

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Number of patients: 51 subjects divided into 3 groups (17 subjects per group)

Diagnosis and main inclusion criterion:

Diagnosis: Primary open-angle glaucoma or ocular hypertension

Main criteria:

* Patients of either sex
* Average intraocular pressure (IOP) ≤ 36 mm/Hg
* Previous management with ocular hypotensive medications ≥ 2 months, without achieving control (target IOP)
* Age ≥ 18 years
* Informed consent

Test product, dosage and route of administration:

* PRO-122. Preservative-free ophthalmic solution of timolol 0.5% / brimonidine 0.2% / dorzolamide 2% Manufactured by Laboratorios Sophia, S.A. de C.V., Zapopan, Jalisco, Mexico. + Placebo + Placebo
* Dosage: 1 drop every 12 hours
* Route of administration: ophthalmic

Treatment duration: 90 days

Evaluation criteria:

Efficiency (non-inferiority):

* IOP decrease

Safety:

* Best corrected visual acuity
* Cup-to-disc ratio
* Visual fields determined by computerized perimetry
* Central corneal thickness determined by pachymetry
* Ocular surface integrity, including:

* Conjunctival hyperemia
* Chemosis
* Fluorescein staining
* Density of goblet cells
* Adverse events

Tolerability:

* Ocular comfort index

Statistical methodology:

The data will be expressed with measures of central tendency: mean and standard deviation for quantitative variables. The qualitative variables will be presented in frequencies and percentages. Statistical analysis will be done by means of a Kruskal-Wallis test for quantitative variables. The difference between qualitative variables will be analyzed using an square chi An alpha ≤ 0.05 would be considered as significant.

Blinding Strategy

DOUBLE

Participants Investigators
Blinding will be performed by the personnel assigned by the Laboratorios Sophia S.A. de C.V. Clinical Operations Management. The blinding will consist in the elimination of the primary label (commercial) for Krytantek Ofteno® and the triple concomitant therapy and the placement of a label identical to those of the other interventions. Since the bottles in which Krytantek Ofteno® and the concomitant therapies are different in color and cap shape to the ones used for the placebo and the PRO-122, a masking will be performed in the primary packaging, which shall be identical for all three interventions.

Study Groups
