Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Changes from baseline (Day 0) in independent investigator-rated ocular itch scores

    Changes from baseline (Day 0) in independent investigator-rated ocular itch scores were assessed at visit 5 (Day 14±2) (study eye). The ocular itch score was graded from 0 to 3(0=none, 1=mild, 2=moderate, 3=severe)

    Day 0~Day 14

Secondary Outcomes (1)

  • Changes from baseline (Day 0) in independent investigator-rated total score of ocular itch, conjunctival hyperemia, and tearing total score

    Day 0~Day 14

Study Arms (2)

EXPERIMENTAL

Administered Epinastine hydrochloride eye drops+Simulating Azelastine hydrochloride eye drops bilaterally, twice daily

Drug: Epinastine Hcl Oph Soln+Simulating Azelastine Hcl Oph Soln

ACTIVE COMPARATOR

Administered Azelastine hydrochloride eye drops+Simulating Epinastine hydrochloride eye drops bilaterally, twice daily

Drug: Azelastine Hcl Oph Sol+Simulating Epinastine Hcl Oph Soln

Interventions

Epinastine Hydrochloride Eye Drops + Simulating Azelastine Hydrochloride Eye Drops are used: both eyes are administered twice daily, once in the morning and once in the evening, with an interval of 8-12 hours between administrations; each time, 1 drop of each of the two eye drops is placed in each eye into the conjunctiva, and the two eye drops are applied at intervals of more than 5 minutes.

You may qualify if:

  • Able to understand and voluntarily sign the informed consent form, and able to comply with the treatment plan, visits, and laboratory tests stipulated in the study. subjects under 18 years of age and without full capacity for civil behavior are required to sign the informed consent form in writing, and a legal guardian is also required to sign the informed consent form;
  • The age on the date of signing the informed consent is equal to or greater than 12 years old, gender is not limited;
  • Have any one of the following three laboratory report records prior to randomization:
  • Positive eosinophil cytology results;
  • Positive specific immunoglobulin E (IgE) test;
  • Positive skin prick test;
  • Clinician-diagnosed seasonal allergic conjunctivitis in both eyes based on history, symptoms, and signs.

You may not qualify if:

  • 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 retinal detachment, diabetic retinopathy, or the presence of any progressive retinal disease in either eye;
