Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a single-center, randomized, double-masked, parallel study. In this clinical study, the efficacy comparison between Pataday® Once Daily Relief Extra Strength and Claritin® Tablets 24-Hour will be made using the Ora-CAC model, a validated clinical model accepted by regulatory agents for assessing the efficacy of products on the signs and symptoms of allergic conjunctivitis.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing olopatadine hydrochloride ophthalmic solution 0.7%, loratadine 10 mg and Tears Naturale in people with Allergic Conjunctivitis, run by Andover Research Eye Institute 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 11 inclusion and 12 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 3 May 2022. 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 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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 3(±1) minutes post-CAC at Visit 3 (time frame: 3(±1) minutes post-CAC on Day 1 (Visit 3)). The study lists 6 primary outcomes in all. 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 3 May 2022.
