What is being measured

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

  1. Ocular Itching Evaluated by the Subject 3 Minutes Post Challenge on Day 0

    Ocular itching is evaluated by the subject at 3 minutes post challenge on Day 0 (Visit 3B). Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less itching.

    Measured: Day 0 at 3 Minutes Post Challenge

Secondary outcomes (10)
  1. Ocular Itching Evaluated by the Subject at 5 and 7 Minutes Post Challenge on Day 0

    Ocular itching is evaluated by the subject at 5 and 7 minutes post challenge on Day 0 (Visit 3B). Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less itching.

    Measured: Day 0

  2. Percentage of Subjects With Minimal Itching Score at 3, 5, and 7 Minutes Post Challenge on Day 0

    Ocular itching is evaluated by the subject at 3, 5, and 7 minutes post challenge on Day 0 (Visit 3B). Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). Minimal itching is considered a score <1.

    Measured: Day 0

  3. Percentage of Subjects With a Zero Itch Score at 3, 5, and 7 Minutes Post Challenge on Day 0

    Ocular itching is evaluated by the subject at 3, 5, and 7 minutes post challenge on Day 0 (Visit 3B). Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). Zero itch is considered a score = 0.

    Measured: Day 0

  4. Percentage of Subject Eyes in Each Category of the Itching Score Distribution Post Challenge on Day 0

    Ocular itching is evaluated by the subject at Hour 16 post challenge on Day 0. Subjects score their ocular itching on a 9-point numeric analog scale ranging from 0=None to 4=Incapacitating Itch with an Irresistible Urge to Rub (0.5 increments are allowed).

    Measured: Day 0

  5. Conjunctival Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 0

    The conjunctiva is a thin membrane that covers the inner surface of the eyelid and the white part of the eye. Conjunctival redness is evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Investigators score conjunctival redness on a 9-point numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less conjunctival redness.

    Measured: Day 0

  6. Ciliary Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 0

    Ciliary redness is redness spreading out around the cornea of the eye. Ciliary redness is evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Investigators score ciliary redness on a 9-point numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less ciliary redness.

    Measured: Day 0

  7. Episcleral Redness Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 0

    The episclera is the tissue that lies over the white part of the eye. Episcleral redness is evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Investigators score episcleral redness on a 9-point numeric analog scale ranging from 0=None to 4=Extremely Severe (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less episcleral redness.

    Measured: Day 0

  8. Chemosis Evaluated by the Investigator at 7, 15, and 20 Minutes Post Challenge on Day 0

    Chemosis is swelling of the tissue that lines the eyelids and surface of the eye. Chemosis is evaluated by the investigator at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Investigators score chemosis on a 9-point numeric analog scale ranging from 0=None to 4=Severe (0.5 increments are allowed). For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less chemosis.

    Measured: Day 0

  9. Eyelid Swelling Evaluated by the Subject at 7, 15, and 20 Minutes Post Challenge on Day 0

    Eyelid swelling is evaluated by the subject at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Subjects score eyelid swelling on a 4-point numeric analog scale ranging from 0=None to 3=Severe. For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less lid swelling.

    Measured: Day 0

  10. Tearing Evaluated by the Subject at 7, 15, and 20 Minutes Post Challenge on Day 0

    Tearing is evaluated by the subject at 7, 15, and 20 minutes post challenge on Day 0 (Visit 3B). Subjects score tearing on a 5-point numeric analog scale ranging from 0=None/Normal to 4=Very Severe. For each subject, the score for both eyes is averaged (i.e., one score per subject). A lower score is indicative of less tearing.

    Measured: Day 0

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Alcaftadine 0.25%, Olopatadine 0.2% and dextran 70 0.1%/hydroxypropyl methylcellulose 0.3% in people with Conjunctivitis, Allergic, run by Allergan 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 2 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 14 Jan 2014. 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. Some participants in this study may receive a placebo. 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 14 Jan 2014). 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 Evaluated by the Subject 3 Minutes Post Challenge on Day 0 (time frame: Day 0 at 3 Minutes Post Challenge). 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 NCT01732757, 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 14 Jan 2014.
