Overview

This is a first-in-human, single-center, randomized, double-blind, placebo-controlled clinical trial designed to:·Evaluate the efficacy of JN002 Ophthalmic Solution in treating dry eye disease (DED)·Assess the safety of JN002 Ophthalmic SolutionResearchers will compare three groups-placebo (vehicle), low-dose JN002 (0.05 mg/mL), and high-dose JN002 (0.1 mg/mL)-to evaluate whether JN002 Ophthalmic Solution improves DED outcomes and to assess its safety profile relative to placebo.Participants will:·Complete a baseline assessment (V0) including ocular exams, OSDI questionnaire, and systemic evaluation;·Administer the assigned study medication three times daily (1 drop per eye per administration);·Attend three follow-up visits (V1: 7±2 days, V2: 14±2 days, V3: 28±2 days post-treatment initiation) for ocular assessments, symptom queries, and adherence checks;·Undergo a full repeat of baseline assessments at V3 to evaluate treatment effects and safety profile
