Study Description

Brief Summary:

The purpose of this study is to evaluate whether SkQ1 Ophthalmic Solution is safe and effective compared to Vehicle for the treatment of the signs and symptoms of dry eye syndrome.

Condition or disease	Intervention/treatment	Phase
Dry Eye Syndrome	Drug: SkQ1 Vehicle Solution; Drug: SkQ1 Ophthalmic Solution	Phase 3

Detailed Description:

Multi-center, double-masked, randomized, placebo-controlled study comprising 5 visits over the course of approximately 9 weeks. Qualified subjects are randomized 1:1 to receive either SkQ1 Ophthalmic Solution, or Placebo (vehicle of SkQ1 Ophthalmic Solution).

The Primary Endpoints are:

Change from Baseline (Visit 2) to Visit 5 of Ocular Discomfort;

Change from Baseline (Visit 2) to Visit 5 of conjunctival fluorescein staining (sum of temporal and nasal regions)

Study Design

• Study Type: Interventional (Clinical Trial)
• Actual Enrollment: 610 participants
• Allocation: Randomized
• Intervention Model: Parallel Assignment
• Intervention Model Description: Parallel Assignment Parallel-group study SkQ1 Ophthalmic Solution versus placebo (vehicle) solution
• Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
• Primary Purpose: Treatment
• Official Title: A Phase 3, Multi-Center, Randomized, Double-Masked, Placebo-Controlled Study of Safety and Efficacy of SkQ1 Ophthalmic Solution in the Environment and the Controlled Adverse Environmental (CAE®) Model for the Treatment of Dry Eye Syndrome
• Actual Study Start Date: December 20, 2019
• Actual Primary Completion Date: October 6, 2020
• Actual Study Completion Date: October 6, 2020

Arms and Interventions

Arm	Intervention/treatment
Placebo Comparator: Placebo Comparator: SkQ1 Vehicle; Vehicle for SkQ1 Ophthalmic Solution	Drug: SkQ1 Vehicle Solution; SkQ1 Ophthalmic Solution Vehicle; Other Name: Vehicle for SkQ1
Active Comparator: SkQ1; SkQ1 Ophthalmic Solution	Drug: SkQ1 Ophthalmic Solution; SkQ1 Ophthalmic Solution; Other Name: Visomitin

Outcome Measures

Primary Outcome Measures :

1. Ocular Discomfort Scale [ Time Frame: From baseline to Day 57 ]
   Change of Ocular Discomfort Scale, scale ranged from 0 to 4 with 0 = No Discomfort and 4 = Constant Discomfort.
2. Conjunctival Fluorescein Staining [ Time Frame: From baseline to Day 57 ]
   Change of Conjunctival Fluorescein Staining (sum of temporal and nasal regions), scale in each region ranged from 0 to 4 with 0 = No Staining and 4 = Confluent Staining
