Clinical Trial Summary

Title of the study Efficacy and safety of PRO-155 (Zebesten ofteno®) on inflammation of the conjunctival surface in subjects with grade I-III pterygium vs placebo.

Hypothesis H0. The Zebesten® ophthalmic solution (bromfenac 0.09%) is less effective and safe than placebo in reducing conjunctival hyperemia in subjects with grade I-III pterygium.

H1 The Zebesten® ophthalmic solution (bromfenac 0.09%) is more effective and safe than placebo in reducing conjunctival hyperemia in subjects with grade I-III pterygium.

Objective

To evaluate the efficacy and safety of PRO-155 (bromfenac 009%) ophthalmic solution in the treatment of conjunctival hyperemia and ocular surface inflammation in a clinical model of pterygium grade I to III.


Clinical Trial Description

Variables to be evaluated Visual ability Intraocular pressure. Ocular surface Exploration of the previous segment. Exploration of the posterior segment. Lacrimal rupture time. Corneal de-epithelialization Conjunctival de-epithelialization Adverse events.

PHARMACOLOGICAL INTERVENTION

The pharmacological intervention will consist of the instillation of the ophthalmological solution in the conjunctival cul-de-sac, during the waking period, to any of the following study groups:

- Group 1:

- Sodium hyaluronate 0.4% [Lagricel ofteno®] 1 drop 3 times a day in the period of vigil in the conjunctival sac fund (the following application scheme is suggested: start: 7:00 ± 1 hours, continuation: 15:00 ± 1 hour and term: at 19:00 ± 1 hours) for 20 days

- Pro-155 1 drop 2 times a day in the period of vigil in the conjunctival cul-de-sac (the following application scheme is recommended: start: 7:15 ± 1 hours and term: at 19:15 ± 1 hours) during 20 days

- Group 2:

- Sodium hyaluronate 0.4% [Lagricel ofteno®] 1 drop 3 times a day in the period of vigil in the conjunctival sac fund (the following application scheme is suggested: start: 7:00 ± 1 hours, continuation: 15:00 ± 1 hour and term: at 19:00 ± 1 hours) for 20 days

- Placebo 1 drop 2 times a day in the period of vigil in the conjunctival cul-de-sac (the following application scheme is recommended: start: 7:15 ± 1 hours and term: at 19:15 ± 1 hours) for 20 days ;
