NCT01382654 ↗ Two Formulations and Concentrations of Epinastine Nasal Spray Versus Azelastine Nasal Solution for Allergic Rhinitis Completed Merck Sharp & Dohme Corp. Phase 2 2006-09-01 The objectives of this study were to: - Examine the tolerability of two formulations and two dose concentrations of epinastine. - Select formulation(s) of epinastine for future studies by evaluating the individual sensory attribute scores of the Nasal Spray Evaluation Questionnaire (NSEQ) collected after each study drug administration and the subject preference ranking assessed at the completion of the study. - Compare the preference of two formulations and two dose concentrations of epinastine compared to azelastine following a single dose of each in a randomized, double-blind, two-cohort, three-period crossover design.
NCT01569191 ↗ Non-Pharmaceutical Treatment of Seasonal Allergic Conjunctivitis Completed University of Worcester Phase 4 2012-03-01 Seasonal allergic conjunctivitis (SAC) is an irritating eye condition that affects many people, caused by hypersensitivity to normally harmless substances such as pollen, and often accompanies seasonal hay fever. Treatments that can be used before initiating medical therapy include artificial tear supplements (ATS) and cold compresses (CC). However, there is no evidence in the scientific literature that demonstrates their efficacy compared to no treatment or their combined effect with anti-allergic medication. Therefore the investigators aim to examine the efficacy of ATS and CC alone, in comparison to anti-allergic medication, and CC in combination with anti-allergic medication. In addition, the investigators also aim to determine the time course of ocular allergic reactions. At the end of the study the investigators will be able to see whether or not ATS and CC are effective in treating SAC.

Epinastine Hydrochloride: Clinical Trials, Market Analysis, and Projections

Introduction to Epinastine Hydrochloride

Epinastine hydrochloride is a selective histamine H1 receptor antagonist that also inhibits IgE receptor-mediated histamine release from mast cells. It is primarily used in the treatment of allergic conjunctivitis, providing relief from symptoms such as itching, redness, and swelling associated with ocular allergies.

Clinical Trials Update

Recent Phase III Clinical Trials

Several recent clinical trials have been conducted to evaluate the efficacy and safety of epinastine hydrochloride for the treatment of seasonal allergic conjunctivitis.

  • Zhaoke Ophthalmology Limited's Trial: This multicenter, randomized, double-blind, positive-controlled Phase III clinical study involved approximately 14 centers and enrolled 266 patients. The trial aimed to evaluate the efficacy and safety of 0.05% epinastine hydrochloride eye drops. Patient enrollment was completed ahead of schedule, and the last patient visit was concluded on September 28, 2023[3].
  • Non-Inferiority Trial: Another multicenter, randomized, double-blind, active control, non-inferiority clinical trial compared the efficacy of epinastine hydrochloride eye drops to azelastine hydrochloride eye drops in Chinese patients. Participants were treated with either epinastine hydrochloride or azelastine hydrochloride eye drops twice a day for 14 consecutive days. The study aimed to determine if epinastine hydrochloride is non-inferior to azelastine hydrochloride in treating seasonal allergic conjunctivitis[4].

Efficacy and Safety Findings

Previous studies have shown that epinastine hydrochloride is effective and safe for the treatment of allergic conjunctivitis. A study published in the American College of Allergy, Asthma & Immunology journal demonstrated that epinastine significantly inhibited ocular itching and conjunctival hyperemia induced by cedar pollen antigen. It also showed noninferiority to olopatadine and had a good safety profile with no adverse drug reactions or serious adverse events reported[1].
