A Study to Evaluate the Efficacy and Safety of Epinastine Hydrochloride Eye Drops in the Treatment of Chinese Seasonal Allergic Conjunctivitis Patients
China266 participantsStarted 2023-03-13
Plain-language summary
The goal of this multicenter, randomized, double-blind, active control, non-inferiority clinical trial is to evaluate the efficacy of epinastine hydrochloride eye drops for the treatment of seasonal allergic conjunctivitis using azelastine hydrochloride eye drops as a positive control in Chinese patients. The main question it aims to answer are:
• Is the efficacy for of epinastine hydrochloride eye drops for the treatment of seasonal allergic conjunctivitis non-inferior to azelastine hydrochloride eye drops?Participants will be randomly assigned to the test group or control group in a 1:1 ratio. The test group was treated with epinastine hydrochloride eye drops + azelastine hydrochloride simulating eye drops, and the control group was treated with azelastine hydrochloride eye drops + epinastine hydrochloride simulating eye drops, which were used twice a day for 14 consecutive days.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Changes from baseline (Day 0) in independent investigator-rated ocular itch scores
. Clinician-diagnosed seasonal allergic conjunctivitis in both eyes based on history, symptoms, and signs.
Exclusion criteria
. Presence of ocular diseases that may affect the study results at the time of screening in either eye, such as blepharitis, blepharitis, dacryoadenitis, dacryocystitis, infectious conjunctivitis, keratitis, moderate-to-severe dry eye (according to the diagnostic grading of the Chinese expert consensus on dry eye), and uveitis;
. Conjunctival inflammatory proliferative lesions (including giant papillary hyperplasia, paving stone-like hyperplasia, jelly-like hyperplasia, etc.) within 2 years prior to screening in either eye;
. Best corrected visual acuity (BCVA) of less than 4.4 (five-point visual acuity) in either eye at screening;
. Intraocular pressure\>21 mmHg or \<8 mmHg in either eye at screening;
. Current or previous glaucoma or other optic nerve disease, or suspected glaucoma and other optic nerve disease, in either eye;
. current or previous retinal detachment, diabetic retinopathy, or the presence of any progressive retinal disease in either eye;
. Either eye has had internal eye surgery within 6 months prior to screening or has had laser eye surgery and external eye surgery within 3 months prior to screening or plans to have eye surgery during the study period;
. Ocular trauma within 3 months prior to Screening in either eye (except where, in the judgment of the Investigator, there is no impact on the study validity and safety results);
