About this study

Official title: Study of Non-inferiority Between Manzanilla Sophia® and Meticel Ofteno® 0.5% for Providing a Relief Sensation to the Eyes

Demonstrate the non-inferiority of Manzanilla Sophia® compared to Meticel Ofteno® 0.5% in providing a sensation of eye relief, through the score of an analogous visual test for eye fatigue.

Read the detailed description

Primary Objective:

Demonstrate the non-inferiority of Manzanilla Sophia® compared to Meticel Ofteno® 0.5% in providing a sensation of eye relief, through the score of an analogous visual test for eye fatigue.

Secondary Objectives:

Signs and Symptoms Evaluated:

  • Compare Manzanilla Sophia® to Meticel Ofteno® 0.5% in the incidence of red eye.
  • Compare Manzanilla Sophia® to Meticel Ofteno® 0.5% in the incidence of dry eye sensation.
  • Compare Manzanilla Sophia® to Meticel Ofteno® 0.5% in the incidence of eye irritation.
  • Compare Manzanilla Sophia® to Meticel Ofteno® 0.5% in the incidence of sensation of eye discharge (sleep).

Safety Assessment:

  • Compare the incidence of adverse events (AEs) related to the interventions.

What is being measured

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

  1. The Proportion of Participants Who Decreased ≥ 6 Points or the Equivalent of 20% or More in the Visual Analog Test Score Compared to Their Baseline

    To demonstrate the non-inferiority of Manzanilla Sophia® compared to Meticel Ofteno® 0.5% in providing a sensation of eye relief, through the score of an analogous visual test for eye fatigue. Based on other tools previously used for the assessment of eye fatigue, the visual analog test for eye fatigue used in this protocol is adapted and created. This test includes the following questions: "Have you had a headache?", "Have you had eye strain?", "Do you have gritty sensation in your eyes?", "Have your eyes been itchy?", "How would you describe your clarity of sight?", "Do you feel any discomfort when you fix your eyes?". Each of these questions will be answered according to a Likert scale of 1-5. The sum of the answers, the total score, will be measured in a scale from 6 to 30. A higher score is a a worse outcome for this variable.

    Measured: Day 8 (Final visit)

Secondary outcomes (5)
  1. Comparison of Manzanilla Sophia® and Meticel Ofteno® 0.5% in the Incidence of Red Eye

    The presence of red eye (presence/absence) will be assessed based on direct observation by the investigator.

    Measured: Day 0 (Basal visit), Day 8 (Final visit)

  2. Comparison of Manzanilla Sophia® and Meticel Ofteno® 0.5% in the Incidence of Dry Eye Sensation.

    This symptom was obtained by direct questioning of the subject by the principal investigator, and the response was recorded as present/absent.

    Measured: Day 0 (Basal visit), Day 8 (Final visit)

  3. Comparison of Manzanilla Sophia® and Meticel Ofteno® 0.5% in the Incidence of Eye Irritation

    This symptom was obtained by direct questioning of the subject by the principal investigator, and the response was recorded as present/absent.

    Measured: Day 0 (Basal visit), Day 8 (Final visit)

  4. Comparison of Manzanilla Sophia® and Meticel Ofteno® 0.5% in the Incidence of Sensation of Eye Discharge.

    This symptom was obtained by direct questioning of the subject by the principal investigator, and the response was recorded as present/absent.

    Measured: Day 0 (Basal visit), Day 8 (Final visit)

  5. Comparison of Manzanilla Sophia® and Meticel Ofteno® 0.5% in the Incidence of Comfort With the Application of the Investigational Product (IP).

    This result was obtained by the principal investigator directly questioning the subject, and the response was recorded as present/absent.

    Measured: Day 8 (Final visit)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Manzanilla Sophia® and Meticel Ofteno® 0.5% in people with Ophthalmological Agent Toxicity, 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 5 inclusion and 7 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: finished, as of the sponsor's last update on 8 Apr 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 8 Apr 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?

The Proportion of Participants Who Decreased ≥ 6 Points or the Equivalent of 20% or More in the Visual Analog Test Score Compared to Their Baseline (time frame: Day 8 (Final visit)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 8 Apr 2026.
