Non-inferiority of PRO-122 Ophthalmic Solution vs KRYTANTEK Ofteno® in Glaucoma or Ocular Hypertension (CONFORTK) — CONFORTK  

Ocular Hypertension Clinical Trial

Official title: Clinical Study to Evaluate the Non-inferiority of PRO-122 an Ophthlamic Solution Manufactured by Laboratorios Sophia, Previous Treatment With Krytantek Ofteno ®, in Subjects With Primary Open-Angle Glaucoma or Ocular Hypertension.

Status Completed

Clinical Trial Summary

Aim: To demonstrate the non-inferiority of the PRO-122 ophthalmic solution manufactured by Laboratorios Sophia S.A. de C.V. versus Krytantek Ofteno® ophthalmic solution like hypotensive therapy in subjects with primary open angle glaucoma or ocular hypertension.

Study design: a multicentric, prospective, crossover (2x2), double blind clinical study. Sample size: one hundred patients with primary open angle glaucoma or ocular hypertension. Patients in the period 1: In the first sequence 30 patients will be assigned to receive the ophthalmic solution: Krytantek Ofteno ® (timolol 0.5%%/brimonidine 0.2%/dorzolamide 2%) 1 drop B.I.D. during 30 days and the second sequence 30 patients will be assigned to receive the ophthalmic solution: PRO-122 1 drop B.I.D. during 30 days in the same period. Washout period: 20 hours. Patients in the period 2: the pharmacological intervention change to the opposite therapy for 30 days

Clinical Trial Description

The American Academy of Ophthalmology Glaucoma Panel: The primary open angle glaucoma (POAG) is a progressive, chronic optic neuropathy in adults in which intraocular pressure (IOP) and other currently unknown factors contribute to damage and in which, in the absence of other identifiable causes, there is a characteristic acquired atrophy of the optic nerve and loss of retinal ganglion cells and their axons. This condition is associated with an anterior chamber angle that is open by gonioscopic appearance.

This is a multicentric, crossover, double blind and prospective clinical study. The investigators will include patients with confirmed diagnosis of primary open-angle glaucoma or ocular hypertension, with target intraocular pressure (TIOP) within a range at which a patient is likely to remain stable or at which worsening of glaucoma will be slow enough that the risk of additional intervention is not justified.

Patients will be randomly divided into 2 groups, one of them treated with a known formulation of timolol 0.5%/brimonidine 0.2%/dorzolamide 2% (Krytantek Ofteno®, Laboratorios Sophia, Mexico) and the other one treated with PRO-122 ophthalmic solution. Patients will receive 1 drop B.I.D. into the lower conjunctival sac of either formulations and were examined at days: 1, 15, 30, 45 and 61 after initiation of treatment. A phone call security at day 75 will be performed.

Primary efficacy outcome: To evaluate the efficacy of PRO-122 versus Krytantek Ofteno® instilled onto the ocular surface in subjects with primary open angle glaucoma (POAG) or ocular hypertension (HTO), to control and maintenance of the target intraocular pressure (TIOP). ;
