Assessment of the Safety and Efficacy of RGN-259 Ophthalmic Solutions for Dry Eye Syndrome: ARISE-1

Registered clinical trial record on ClinicalTrials.gov (NCT02597803). This describes a planned, ongoing, or completed study — it is NOT peer-reviewed results. Status: completed. Study type: interventional. Phase: Phase 2/Phase 3. Sponsor: ReGenTree, LLC. Conditions: Dry Eye Syndrome. Interventions: RGN-259, Placebo. Summary: The objective of this study is to compare the safety and efficacy of RGN-259 Ophthalmic Solutions to placebo for the treatment of the signs and symptoms of dry eye. Dry eye can be caused by many variable factors. Some examples include hormonal changes due to aging, or living in an environment of low humidity for long periods of time. Dry eye is a complex disease that may result in symptoms like discomfort, visual disturbance, and dryness. Patients with dry eye often have damage on the surface of the eye. In previous studies, RGN-259 has been shown to promote healing of the surface of the eye and decrease inflammation. It suggests that RGN-259 has a significant potential to be an important new safe and effective therapeutic in the treatment of dry eye syndrome. Primary outcome measures: Total corneal fluorescein staining score at day29; Total ocular discomfort score at day29.
