A Non-inferiority in the Intraocular Pressure Decrease of the Preservative-free Ophthalmic Solution PRO-122 Versus Concomitant Therapy in Subjects With Uncontrolled Primary Open-angle Glaucoma

SOPH122-0316/III

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
