March 3, 2026 updated by: Huons Co., Ltd.

A Multicenter, Randomized, Double-blinded, Non-inferiority Phase 3 Study to Evaluate the Efficacy and Safety of HUC3-053 Compared With Hyalein Mini Eye Drops in Patients With Dry Eye Syndrome

This is a multi-center, randomized, double-blinded, non-inferiority study to evaluate the efficacy and safety of HUC3-053 in patients with dry eye syndrome.

After a 2-week run-in period, patients will be randomized equally to the HUC3-053 or Hyalein Mini Eye Drops administered bilaterally five to six times a day for 12 weeks.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multi-center, randomized, double-blinded, non-inferiority study to evaluate the efficacy and safety of HUC3-053 in patients with dry eye syndrome.

During a 2-week study run-in period prior to randomization, all subjects will receive rescue drug bilaterally up to 4 times a day. Randomization will then occur as 1:1 where patients will be assigned to receive HUC3-053 or Hyalein Mini Eye Drops given bilaterally five to six times a day. The treatment period is 12 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No
