A Study to Evaluate the Efficacy and Safety of Epinastine Hydrochloride Eye Drops in the Treatment of Chinese Seasonal Allergic Conjunctivitis Patients
A Phase 3, Multicenter, Randomized, Double-masked, Active Controlled Study to Evaluate the Efficacy and Safety of Epinastine Hydrochloride Eye Drops 0.05% in the Treatment of Chinese Seasonal Allergic Conjunctivitis Patients
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.

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;

- 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);
- Presence of a systemic disease at the time of screening that may affect the results of the study, e.g., dry syndrome, rheumatoid arthritis, graft-versus-host disease, systemic lupus erythematosus, scleroderma, and tuberculosis;
- Presence of severe, unstable, or uncontrolled cardiovascular, cerebral, pulmonary, hepatic, renal, autoimmune, and other relevant systemic diseases at the time of screening, e.g., severe chronic obstructive pulmonary disease (COPD), severe asthma, severe cardiac arrhythmia, significant heart failure (New York Heart Association classification ≥ Class III), uncontrolled hypertension (systolic blood pressure ≥ 160 mmHg or diastolic blood pressure ≥ 90 mmHg ), uncontrolled diabetes, etc;
- History of medical conditions that, in the judgment of the investigator, may interfere with the safe administration of topical antihistamines/mast cell stabilizers, such as hepatic or renal impairment (ALanine aminoTransferase(ALT) or ASpartate aminoTransferase(AST) ≥ 2.5 times the upper limit of normal; total bilirubin ≥ 1.5 times the upper limit of normal; and serum creatinine or urea/urea nitrogen ≥ 1.2 times the upper limit of normal), in the 6 months prior to screening;
The following topical (ophthalmic) prohibited drugs have been used or are planned to be used during the study period within the time period specified prior to randomization (the number of days is the pre-randomization period of prohibition and does not include experimental drugs):
- Ocular immunosuppressive drugs (e.g. cyclosporine, tacrolimus, etc.): 60 days;
- Ocular corticosteroid drugs (dexamethasone, flumethasone, prednisone acetate, rimexolone, difluprednate, loteprednol, etc.): 45 days;
- Ocular mast cell stabilizing drugs: 14 days;
- Ocular antihistamine and decongestant drugs: 3 days;
- Ocular artificial tears: 1 day;
- Other ophthalmic drugs: 3 days.
The following topical (dermal or nasal spray) prohibited medications have been used for the time specified prior to randomization or are planned to be used for the duration of the study (the number of days is the duration of prohibition prior to randomization):
- Antihistamines and corticosteroids for periocular skin: 7 days;
- Nasal spray immunosuppressive drugs: 60 days;
- Nasal spray corticosteroid drugs: 45 days;
- Nasal spray mast cell stabilizing drug: 14 days;
- Nasal spray antihistamine and decongestant drugs: 3 days.
The following systemically prohibited drugs have been used or are planned to be used during the study period within the time period specified prior to randomization (the number of days is the time of prohibition prior to randomization):
