What is being measured

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

  1. Ocular Itching

    Ocular itching scores were self-assessed by the participant using a 5-point scale with 0.5 unit increments, wherein 0 = None (normal, no itching), 1.0 = Intermittent tickle sensation involving more than just the corner of the eye, 2.0 = Mild continuous itch without desire to rub, 3.0 = Severe itch with desire to rub, and 4.0 = Incapacitating itch with irresistible urge to rub.

    Measured: 3, 5 and 7 minutes post-Conjunctival Allergen Challenge (CAC) on Day 1

Secondary outcomes (1)
  1. Conjunctival Redness

    The investigator assessed conjunctival redness scores using a 5-point scale with 0.5 unit increments, wherein 0 = None (normal, no dilated blood vessels), 1 = Mild (slightly dilated blood vessels: pink color; can be quadrantal), 2 = Moderate (more apparent dilation, with redder color, involving majority of the vessel bed), 3 = Severe (numerous and obvious dilated blood vessels, with deep red color and no color, or less red with chemosis), and 4 = Extremely Severe (large, numerous, dilated blood vessels characterized by unusually severe deep red color regardless of chemosis and involving the entire vessel bed).

    Measured: 7, 15 and 20 minutes post-Conjunctival Allergen Challenge (CAC) on Day 1

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing EM-100 and Zaditor® in people with Allergic Conjunctivitis, run by Bausch & Lomb Incorporated at 1 site in United States.

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 3 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 Jun 2023. 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 United States. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 17 May 2021). 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?

Ocular Itching (time frame: 3, 5 and 7 minutes post-Conjunctival Allergen Challenge (CAC) on Day 1). 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 Jun 2023.
