Bacterial Conjunctivitis, Ophthalmological Agent Toxicity
Conditions
Brief summary
This is a phase I clinical study evaluating the safety and tolerability of PRO-231 ophthalmic solution through the incidence of unexpected adverse events, incidence of conjunctival hyperemia and chemosis, changes in Best Corrected Visual Acuity (BCVA), changes in ocular surface integrity, compared to VIGAMOXI®.
Detailed description
This is a Phase I, controlled, comparative, parallel-group, single-blind, single-center, controlled clinical trial. The variables to be evaluated include: Primary (safety): * Incidence of unexpected adverse events related to the interventions * Incidence of conjunctival hyperemia and chemosis * Changes in Best Corrected Visual Acuity (BCVA) assessed with Snellen chart * Changes in ocular surface integrity using fluorescein staining, using the standard Oxford scale. Primary (tolerability): \- Changes in the ocular comfort index (OCI) score Secondary (safety): \- Incidence of unexpected adverse events related to the interventions(excluding conjunctival hyperemia and/or chemosis). Secondary (tolerability): \- Presence of other ocular symptoms (burning, foreign body sensation, pruritus and lacrimation).

|---|---|---|
| Incidence of Conjunctival Hyperemia | Days 0 (Basal Visit), 3 (Visit 1), and 8 (Final Visit) | Any signs of conjunctival hyperemia in between interventions. |
| Number of Patients With Any Changes in Grade Measurement of the Integrity of the Ocular Surface (Fluorescein Staining) | Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit) | Number of patients with any changes in the integrity of the ocular surface using fluorescein staining and evaluated through the Oxford scale compared to baseline. The standard Oxford scale for fluorescein staining has the following criteria: Grade 0- Equal to or less than panel A; Grade I- Equal to or less than panel B, greater than panel A; Grade II- Equal to or less than panel C, greater than panel B; Grade III- Equal or less than panel D, greater than panel C; Grade IV- Equal or less than panel E, greater than panel D; Grade V- Greater than panel E. |
| Changes in the Ocular Comfort Index (OCI) Score Between Interventions. | Days 0 (Basal Visit), and 8 (Final Visit) | The Ocular Comfort Index is a questionnaire designed to measure ocular surface irritation. It assesses symptoms related to comfort in cases of ocular surface disorders. The Ocular Comfort Index is composed of 12 items that assess the frequency and intensity symptoms. Each item is scored on a scale from 0 to 6 (never to always, or absent to severe). The total score becomes a linear continuous interval scale, which ranges from 0 (least symptomatic) to 100 (most symptomatic). The questionnaire was administered to each research subject, allowing them to respond calmly without any pressure and/or coercion. The results were collected using the Ocular Comfort Index calculator \[1\], obtaining a logit score and a 0-100 scale score for each subject. \[1\].- M. E.
