What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Intraocular Pressure (IOP)

    Measured through Goldman tonometer in milligrams of mercury (mmHg). After instillation of topical anesthetic (tetracaine 0.5%) and fluorescein stain, IOP is evaluated at 9:00 and at 11:00 hrs. (± 30 minutes). Both measurements and their average will be registered. Normal values are considered between 10 and 21 mmHg. Assessed at the eligibility visit, basal visit, first follow-up visit, second follow-up visit, and final visit, reported only for first follow-up visit, second follow-up visit and final visit.

    Measured: Days: -30 (± 2) (eligibility visit), 0 (basal visit), 14 (± 2) (first follow-up visit), 30 (± 2) (second follow-up visit) and 60 (± 2) (final visit)

Secondary outcomes (10)
  1. Best Corrected Visual Acuity (BCVA)

    Visual acuity (VA) is a test of visual function. It will be evaluated with the Snellen chart. The Snellen chart is the standard tool used to evaluate visual acuity. It was located in a place with adequate lighting, natural or artificial and at a distance of 3 meters from the subject to be evaluated. The contralateral eye to which it will be evaluated is covered, then the examiner detects until the line can clearly see the letters given he or she a score, the normal score for a VA is 20/20.This score can be expressed in fraction (i.e. 20/20) decimal (i.e. 1.0), or LogMAR (i.e. 0) formats. In this study, VA is expressed in decimal format. In decimal format, a lower number is a worse outcome.

    BCVA was compared between groups and between visits. Assessed at the eligibility visit, basal visit, first follow-up visit, second follow-up visit, and final visit, reported only for first follow-up visit, second follow-up visit and final visit.

    Measured: Days: -30 (± 2) (eligibility visit), 0 (basal visit [BV]), 14 (± 2) (first follow-up visit [V1]), 30 (± 2) (second follow-up visit [V2]) and 60 (± 2) (final visit [FV])

  2. Optic Nerve Cup/Disc Ratio (Baseline Vist vs Final Visit)

    Both clinical and imaging evaluation will be performed. For clinical evaluation, after the application of a topical ophthalmic mydriatic (tropicamide 0.8% / phenylephrine 5%), indirect ophthalmoscopy will be performed through the aid of a fundus lens in a slit lamp. For imaging, optic coherence tomography (OCT) will be used. Assessed and reported only for the basal visit and final visit.

    Measured: Days: 0 (basal visit) and 60 (± 2) (final visit)

  3. Mean Value in Nerve Fibers and Ganglion Cell Thickness

    Spectral domain OCT is a non invasive tool that will be used to evaluate quantitatively the thickness of retinal nerve fibers and ganglion cell layers. The mean observed in the nerve fibers and ganglion cell thickness was calculated. This was assessed and reported only for the basal and final visit.

    Measured: Days: 0 (basal visit) and 60 (± 2) (final visit)

  4. Optic Nerve Image

    Through a fundus camera a photograph will be taken to obtain a faithful record of any possible changes to the optic nerve head characteristics. Its classification as "small", "medium" or "large" relied on the expertise of the PI, the percentage of cases in each classification ("small", "medium" or "large") was reported. Assessed and reported only for the basal visit and final visit.

    Measured: Days: -30 (± 2) (eligibility visit), 0 (basal visit) and 60 (± 2) (final visit)

  5. Central Corneal Thickness (CCT)

    Measured through ultrasonic pachymetry, three assessments will be performed, these and its average will be recorded. Assessed and reported for the basal visit and final visit.

    Measured: Days: 0 (basal visit) and 60 (± 2) (final visit)

  6. Change in Visual Fields

    Visual fields will be assessed using standard automated SITA (Swedish Interactive Thresholding Algorithm) white-on-white perimetry performed with a Humphrey perimeter. To be considered reliable, fixation losses, false positives, and false negatives must be less than 20%.

    The mean deviation (MD) was recorded, which is a measure of overall field loss. The standard deviation of the pattern was also recorded, which is a measure of focal loss or variability within the field. A higher score is a worse result.

    The theoretical value or reported range for the average deviation is from +2.00 to -35 dB.

    Measured: Days: 0 (basal visit) and 60 (± 2) (final visit)

  7. Change in Ocular Surface Integrity (Chemosis)

    By means of a slit lamp chemosis will be evaluated. Chemosis will be evaluated as present (if conjunctiva separates from the sclera in ≥ 1/3 of the palpebral opening area or if it exceeds the eyelid's gray line) or absent. The number and percentage of participants in each category was reported.

    Measured: Days: 0 (basal visit, BV), 14 (± 2) (first follow-up visit, V1), 30 (± 2) (second follow-up visit, V2) and 60 (± 2) (final visit, FV)

  8. Number of Adverse Events

    Presence/absence adverse events, defined as the appearance of any unfavorable reaction in a patient participating in a clinical investigation in which any pharmaceutical product is being administered, regardless of the causal attribution.

    Measured: Day: 75 (± 3) (safety call)

  9. Changes in Ocular Comfort Index

    Ocular Comfort Index (OCI) Questionnaire will be used for evaluation of tolerability through incidence and severity of dry eye symptoms in a scale from 0 to 100. Greater scores mean a worse outcome.

    Measured: Days: -30 (± 2) (eligibility visit), 0 (basal visit), 14 (± 2) (first follow-up visit), 30 (± 2) (second follow-up visit) and 60 (± 2) (final visit)

  10. Change in Ocular Surface Integrity (Conjunctival Hyperemia)

    By means of a slit lamp conjunctival hyperemia will be evaluated. Conjunctival hyperemia will be graded according to Efron's scale (5 grades: Normal (0), Very Mild (I), Mild (II), Moderate (3), and Severe (4)).

    Measured: Days: 0 (basal visit, BV), 14 (± 2) (first follow-up visit, V1), 30 (± 2) (second follow-up visit, V2) and 60 (± 2) (final visit, FV)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dorzolamide-timolol-brimonidine and latanoprost and Dorzolamide-timolol and latanoprost in people with Glaucoma, Open-Angle and Ocular Hypertension, run by Laboratorios Sophia S.A de C.V. at 1 site in Mexico.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 7 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Mexico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 May 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Intraocular Pressure (IOP) (time frame: Days: -30 (± 2) (eligibility visit), 0 (basal visit), 14 (± 2) (first follow-up visit), 30 (± 2) (second follow-up visit) and 60 (± 2) (final visit)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04702789, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 May 2026.
