Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Individuals aged 18 years or older
  • Female subjects of and their male partners must both use a highly effective method during the study.
  • Documented history of ocular allergies and a positive skin test reaction to a seasonal (grass, ragweed, tree pollen) or perennial (cat dander, dog dander, dust mites, cockroach) allergen as confirmed by an allergic skin test conducted at Visit 1 or within the past 60 months.
  • Calculated best-corrected visual activity of 0.7 LogMAR or better
  • Positive bilateral CAC reaction

Exclusion criteria

Exclusion Criteria:

  • Any systemic or ocular disease currently producing ocular redness and/or ocular discomfort, or that may interfere with the conduct of the study.
  • Any ocular surgical intervention within the last 3 months OR refractive surgery within the last 6 months
  • Any ongoing ocular infection (bacterial, viral or fungal)
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Ocular itching

    Ocular itching score will be reported by the subject at 3 timepoints after CAC at Visits 4, 5 and 6. Assessments were reported using a 0-4 numerical scale (0 = none and 4 = incapacitating itch with an irresistible urge to rub).

    Time frame: 3, 5 and 7 minutes after CAC

  2. Conjunctival redness

    Conjunctival redness will be assessed by the investigator at 3 timepoints after CAC at Visits 4, 5 and 6. Assessments were completed using a 0-4 numerical scale (0 = none and 4 = extremely severe).

    Time frame: 7, 15 and 20 minutes after CAC

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 1, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
