Bacterial Conjunctivitis Clinical Trial
Official title:
Phase I Clinical Study to Evaluate the Safety and Tolerability of PRO-231 Ophthalmic Solution Versus VIGAMOXI® on the Ocular Surface of Ophthalmologically and Clinically Healthy Subjects.
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®.

---|---|---|---|---|
Primary | Incidence of unexpected adverse events related to the interventions | Any unfavorable medical condition affecting the subject after the administration of the investigation product, related to such intervention. | Days 0 (Basal Visit), 3 (Visit 1), 8 (Final Visit) and 12 (Safety Call) | |
Primary | Incidence of conjunctival hyperemia and chemosis | Any signs of conjunctival hyperemia and chemosis in between interventions. | Days 3 (Visit 1), and 8 (Final Visit) | |
Primary | Changes in Best Corrected Visual Acuity (BCVA) | The BCVA will be evaluated through Snellen chart. | Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit) | |
Primary | Changes in the integrity of the ocular surface (fluorescein staining) | Changes in the integrity of the ocular surface using fluorescein staining and evaluated through the Oxford scale. 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. | Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit) | |
Primary | Changes in the Ocular Comfort Index (OCI) score between interventions. | The subjects will be questioned regarding this symptoms' incidence. | Days 3 (Visit 1), and 8 (Final Visit) | |
Secondary | Incidence of unexpected adverse events (excluding conjunctival hyperemia and chemosis) | Any unfavorable medical condition affecting the subject after the administration of the investigation product, related to such intervention, excluding conjunctival hyperemia and chemosis. | Days 3 (Visit 1), 8 (Final Visit) and 12 (Safety Call) | |
Secondary | To assess the tolerability of PRO-231 ophthalmic solution | To assess the tolerability of PRO-231 ophthalmic solution applied to the ocular surface, in healthy volunteers, versus VIGAMOXI®, by means of: Presence of ocular symptoms (burning, foreign body sensation, pruritus and lacrimation) between interventions. | Days 3 (Visit 1), 8 (Final Visit) |
