Dry Eye Syndrome | Drug: Low Dose - SkQ1 Drug: High dose - SkQ1 Drug: SkQ1 (Vehicle) | Phase 3 |
Multi-center, double-masked, randomized, placebo-controlled study comprising 5 visits over the course of approximately 9 weeks. Qualified subjects are randomized 1:1:1 to receive either High Dose SkQ1 ophthalmic solution, Low Dose SkQ1 ophthalmic solution, or Placebo (vehicle of SkQ1 ophthalmic solution).
The Primary Endpoints are:
Change from Baseline (Visit 2) to Visit 5 in Corneal Fluorescein Staining;
Change from Baseline (Visit 2) to Visit 5 in Grittiness Symptom
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 452 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Parallel-group study of two strengths of ophthalmic solution versus placebo solution |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
