A Randomized, Single-Blind Clinical Investigation to Compare the Efficacy and Safety of N-Acetyl-Aspartyl-Glutamate (NAAGA) Versus Azelastine Eye Drops in Patients With Allergic Conjunctivitis Associated With Tear Film Dysfunction
In Brief
A Phase 4 clinical trial evaluating NAAGA (N-acetyl-aspartyl-glutamate) 49 mg/mL and azelastine hydrochloride 0.05% for Allergic Conjunctivitis and Dry Eye Disease (DED). Completed, enrolled 134 participants across 1 site.
Detailed Summary
This randomized, single-blind study aims to compare the efficacy and safety of N-acetyl-aspartyl-glutamate (NAAGA) and azelastine hydrochloride eye drops in patients with allergic conjunctivitis associated with tear film dysfunction. A total of 134 atopic patients with mild-to-moderate tear film dysfunction were included. Participants were randomly assigned to receive either NAAGA (49 mg/mL, four times daily) or azelastine (0.05%, twice daily) for four weeks. The primary endpoint is the change in Ocular Surface Disease Index (OSDI) scores from baseline to week 4. Secondary endpoints include tear osmolarity, Schirmer test results, tear break-up time (TBUT), MMP-9 levels, and corneal staining scores. This study seeks to provide evidence for the tailored management of allergic conjunctivitis and tear film dysfunction.

Timeline
Interventions
80 patients were randomly assigned to NAAGA in single dose (49 mg/mL), instilled as 1 drop per eye four times daily for four weeks. Specific diagnostic tests and procedures for dry eye disease were performed at week 0 (baseline), week 2 and week 4.
54 patients were randomly assigned to azelastine hydrochloride 0.05% instilled as 1 drop per eye 2 times a day in the conjunctival sac for for four weeks. Specific diagnostic tests and procedures for dry eye disease were performed at week 0 (baseline), week 2 and week 4.
