About this study

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

This is a phase IV clinical study to demonstrate the non-inferiority of Manzanilla Sophia® compared to Meticel Ofteno® 0.5% in providing restful sensation to the eyes. This will be evaluated by measuring the incidence of unexpected adverse events related to the interventions, the incidence of conjunctival hyperemia and the incidence of sensation of comfort with the application, when applied by the Principal Investigator (PI).

What is being measured

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

  1. Analog visual eyestrain test score

    The PI will evaluate the analog visual eyestrain test score by applying a direct questionnaire to the subject and allowing the subject to answer it calmly without any pressure.

    The analog visual test score is a questionnaire designed to establish the degree of eyestrain (fatigue) according to its symptomatology. This questionnaire will be as follows for frequency: never (1), sometimes (2), 50% of the time (3), almost all the time (4) and all the time (5).

    Measured: Days: 0 (Basal Visit) and 8 (Final Visit).

Secondary outcomes (6)
  1. Incidence of unexpected adverse events related to the interventions

    Any unfavorable medical condition affecting the subject after the administration of the investigation product, related to such intervention.

    Measured: Days 0 (Basal Visit), 3 (Visit 1), 8 (Final Visit) and 10 (Safety Call)

  2. Incidence of conjunctival hyperemia

    Any signs of conjunctival hyperemia in between interventions.

    Conjunctival hyperemia is defined as the red appearance secondary to vasodilatation of the conjunctival blood vessels of variable intensity.

    Measured: Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit)

  3. Incidence of sensation of ocular dryness.

    The subject will be questioned directly.

    Ocular dryness is defined as the subjective sensation of dry eye.

    Measured: Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit)

  4. Incidence of ocular irritation

    The subject will be questioned directly.

    Ocular irritation is defined as the subjective sensation of eye irritation.

    Measured: Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit)

  5. Incidence of sensation of (sleep-crust)

    The subject will be questioned directly.

    Sleep crust is defined as the subjective sensation of the presence of eye discharge.

    Measured: Days 0 (Basal Visit), Days 3 (Visit 1) and 8 (Final Visit)

  6. Incidence of sensation of comfort with the application, when applied by the Principal Investigator (PI)

    The subject will be questioned directly by de PI during the final visit.

    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® in people with Eye Strain and Eye Strain of Both Eyes, run by Laboratorios Sophia S.A de C.V..

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 11 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: withdrawn, as of the sponsor's last update on 14 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.

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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Analog visual eyestrain test score (time frame: Days: 0 (Basal Visit) and 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 14 Feb 2025.
