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

Phase 3

Completed

• Conditions: Primary Open Angle Glaucoma; Ocular Hypertension
• Interventions: Drug: PRO-122; Drug: Krytantek Ofteno®

• Registration Number: NCT03257813
• Lead Sponsor: Laboratorios Sophia S.A de C.V.

Brief 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

Detailed 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).

Arm && Interventions

Group	Intervention	Description
Group B	Krytantek Ofteno®	In group B, therapy with Krytantek Ofteno® will be suspended and changes for PRO-122 for 30 days, in which the subject will be retested and later switched to Krytantek Ofteno® solution which will be used for 30 days until the 60th day, The final visit.
Group A	Krytantek Ofteno®	In group A, therapy with Krytantek Ofteno® will be continued for 30 days, in which the subject will be retested and switched to a PRO-122 solution which will be used for 30 days until the 60th day, The final visit.
Group A	PRO-122	In group A, therapy with Krytantek Ofteno® will be continued for 30 days, in which the subject will be retested and switched to a PRO-122 solution which will be used for 30 days until the 60th day, The final visit.
Group B	PRO-122	In group B, therapy with Krytantek Ofteno® will be suspended and changes for PRO-122 for 30 days, in which the subject will be retested and later switched to Krytantek Ofteno® solution which will be used for 30 days until the 60th day, The final visit.

Primary Outcome Measures

Name	Time	Method
Intraocular Pressure (IOP)	Change from Baseline intraocular pressure at day 30 and 60.	Intraocular pressure, Unit: Millimeters of mercury (mmHg) type of variable: Continuous, Measurement method: Goldman applanation tonometry. Normal intraocular pressure 11-21 mmHg.; The change between the IOP of both groups was compared (sequence 1 versus sequence 2) of the data obtained at the end of each period (day 30 and day 60).

Secondary Outcome Measures

Name	Time	Method
Visual Acuity (VA)	Visual Acuity at Baseline (day 1) crossover visit (day 30) and final visit (day 60)	The VA will be evaluated basally, without refractive correction with the Snellen chart. A Snellen chart is placed at a standard distance: 20 ft. At this distance, the symbols on the line representing "normal" acuity subtend. This line, designated 20/20 is the smallest line that a person with normal acuity can read at a distance of 20fs. the scale consists of 11 lines of letters of different size, the size of the letter gives a fractional value according to the visual acuity of the patient, the value is inversely proportional to the visual acuity, if the denominator is greater the visual acuity will be less.; Line 1: 20/200 Line 2: 20/100, Line 3: 20/70, line 4: 20/50, line 5: 20/40, Line 6: 20/30, line 7: 20/25, Line 8: 20/20, line 9: 20/15, line 10: 20/13, line 11: 20/10. the differences between groups in the basal, cross over and final visit will be evaluated.
