November 28, 2025 updated by: Eye & ENT Hospital of Fudan University

Randomized, Double-Blind, Placebo-Controlled, Single Center Clinical Trial to Evaluate the Safety and Preliminary Efficacy of JN002 Ophthalmic Solution in Adult Patients With Dry Eye Disease

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

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Corneal Fluorescein Staining score
Time Frame: Baseline, 7±2 days, 14±2 days and 28 ± 2 days
Change from baseline in Corneal Fluorescein Staining (CFS) score at the 7±2 days, 14±2 days and 28±2 days follow-up. CFS is evaluated following the guidelines from the National Eye Institute: the corneal surface is divided into five regions (central, superior, inferior, nasal, temporal), with each region assigned a score ranging from 0 to 3, resulting in a total possible score of 0 to 15-higher scores indicate more severe corneal epithelial damage and a worse clinical outcome.
Baseline, 7±2 days, 14±2 days and 28 ± 2 days
Ocular Surface Disease Index score
Time Frame: Baseline, 7±2 days, 14±2 days and 28±2 days
Change from baseline in Ocular Surface Disease Index (OSDI) score at the 7±2 days, 14±2 days and 28±2 days follow-up. OSDI is assessed via a 12-item self-reported questionnaire, where raw scores are converted to a standardized 0-100 scale through a specific calculation, with higher scores indicating more severe ocular surface disease symptoms.
Baseline, 7±2 days, 14±2 days and 28±2 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Schirmer I test
Time Frame: Baseline and 28 ± 2 days
Change from baseline in Schirmer I test result (measuring aqueous tear secretion) at the 28±2 days follow-up.
Baseline and 28 ± 2 days
Tear meniscus height
Time Frame: Baseline and 28 ± 2 days
Change from baseline in tear meniscus height at the 28±2 days follow-up.
Baseline and 28 ± 2 days
Non-invasive tear film break-up time
Time Frame: Baseline and 28 ± 2 days
Change from baseline in non-invasive tear film break-up time (measured via Keratograph 5M) at the 28±2 days follow-up.
Baseline and 28 ± 2 days
Tear inflammatory cytokines
Time Frame: Baseline and 28 ± 2 days
Change from baseline in tear inflammatory cytokines (IL-1β, IL-6, IL-17A, TNF-α, INF-γ) levels at the 28±2 days follow-up.
Baseline and 28 ± 2 days

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Corneal dendritic cell density
Time Frame: Baseline and 28 ± 2 days
Change from baseline in corneal dendritic cell density at the 28±2 days follow-up, assessed and quantified via in vivo corneal confocal microscopy (IVCM)-a specialized imaging tool for ocular surface evaluation.
Baseline and 28 ± 2 days
Best-corrected visual acuity
Time Frame: Baseline, 7 ± 2 days, 14 ± 2 days, and 28 ± 2 days
Best-corrected visual acuity assessed at baseline, 7±2 days, 14±2 days, and 28±2 days.
Baseline, 7 ± 2 days, 14 ± 2 days, and 28 ± 2 days
Intraocular pressure
Time Frame: Baseline, 7±2 days, 14±2 days, and 28±2 days.
